Abstract
Background Totally laparoscopic total gastrectomy (TLTG) has not been generalized because of its technical difficulty during the procedure of digestive tract reconstruction and lack of short-term results. This meta-analysis aimed to evaluate the feasibility and safety of TLTG for gastric cancer.Methods A systematic literature search in various databases from January 1994 to November 2020 was performed. Eligible studies in comparing TLTG and laparoscopy-assisted total gastrectomy (LATG) for gastric cancer were included in this meta-analysis. The results were analyzed according to predefined criteria.Results In the present meta-analysis, the outcomes of 8 non-randomized controlled studies enrolling 1503 patients (819 in the TLTG group and 684 in the LATG group) were pooled. The operation time was significantly shorter in the TLTG group than those in the LATG group (P < 0.01). Estimated blood loss was significantly less in TLTG than that in LATG (P = 0.01). The TLTG group was associated with earlier time to first flatus (P < 0.01) and oral intake (P =0.02). The pooled analysis showed no significant difference in postoperative hospital stay, postoperative complications, number of retrieved lymph nodes, and the proximal margin between TLTG and LATG groups (all P ˃ 0.05).Conclusions TLTG can be a safe and feasible procedure concerning short-term surgical outcomes and complications.

Abstract
Background: Over the last few decades, extra-thyroid 99mTc-pertechnetate uptake has rarely been reported. The clinical characteristics of extra-thyroid 99mTc-pertechnetate uptake were retrospectively analysed to explore the effect of the phenomenon on RAI therapy for DTC and its clinical significance. Methods: In this study, we retrospectively analysed 4930 RAI-treated DTC patients who had undergone 99mTc-pertechnetate scanning. Thirty-eight cases with extra-thyroid 99mTc-pertechnetate uptake were selected. The clinical features, location, location count and extra-thyroid 99mTc-pertechnetate uptake distribution were analysed, combined with the uptake rate, stimulated thyroglobulin (sTg) level, post-therapy whole-body scan and curative effect. Results: The results showed that sixty-five extra-thyroid 99mTc-pertechnetate foci were detected in 38 patients. The proportions of patients with abnormal uptake in the lymph nodes, lungs and bones were 68.4%, 10.5% and 10.5%, respectively. The corresponding uptake rates were 0.2%, 0.2% and 0.8%. The uptake rate was significantly lower in the lymph nodes than in the bones (Z = -2.722, p = 0.019). The uptake rate and sTg were positively correlated (r = 0.36, p = 0.027). 131I uptake was found in 36 cases at the technetium uptake site, and the number of iodine uptake foci was significantly higher than that of 99mTc-pertechnetate uptake foci. The sTg value and pathological staging significantly differed between the excellent and nonexcellent response groups (Z = 2.947, p = 0.003 and Z = 2.348, p = 0.019, respectively). Conclude: Extra-thyroid 99mTc-pertechnetate uptake mostly indicated metastases with specific clinical features, which may have prognostic value for the judgment of iodine uptake function and the RAI therapy plan.

Abstract
Background: In sub-Saharan Africa the treatment gap for mental disorders is high. In 2009, 98·0% of people with mental illness in Sierra Leone were not receiving treatment, partly due to the absence of public psychiatric facilities outside the capital. In response, the Ministry of Health and Sanitation rolled out nurse-led mental health units (MHU) to every district. Methods: We evaluated the roll out of MHU using summary data from all units between 1st January 2015 and 1st January 2017, to establish the burden of diagnoses among service users, pathways to care, treatments provided, and treatment gaps. Negative binomial regressions examine bivariate relationships between diagnoses, treatments, and medication inaccessibility with demographics (age and sex), location (Freetown vs the rest and Ebola endemic regions vs the rest) and year. Results: We collected data from 15 MHU covering 13 districts in 24 months. There were 2401 referrals. The largest age category was 25-34 (23·4%). The prominent diagnoses were epilepsy (43·5%, associated with children) and psychosis (17·5%, associated with males). Reported depression (8·6%) and suicide attempts (33 patients) were low. Ebola endemic regions reported higher rates of grief, trauma, and medically unexplained symptoms. In 24·7% of cases where medication was required, it was not accessible.Conclusions: Nurse-led MHU can have a modest effect on the treatment gap in resource constrained environments such as Sierra Leone, particularly in epilepsy and psychosis.

Published: January 2021

Abstract
Background: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare clonal disease of hematopoietic stem cells. However, the mechanism of proliferative advantage of PNH clone is unclear. Long noncoding RNAs (LncRNAs) have a wide range of biological functions, including regulation of gene expression, cell differentiation, and proliferation, while its role in PNH remains unclear. Methods: In our study, CD59－and CD59+ granulocytes and monocytes from 5 PNH patients were sorted, and LncRNAs and mRNAs were detected by RNA sequencing. The proliferation-related NF-κB pathway was focused on. A total of 8 mRNAs and 5 LncRNAs were verified by qRT-PCR, and analyzed the correlation with clinical data. Meanwhile, the function of LncRNA was studied.Results: LncRNA FAM157C were verified to be upregulated in PNH clone cells, which were positively correlated with LDH level and CD59- granulated and monocytes cells ratio. After knockdown of FAM157C gene in PIGA-KO-THP-1 cell line, we found that the cells were blocked in G0/G1 phase and S phase, and the apoptosis rate increased, while the proliferation ability decreased. Conclusions: LncRNA FAM157C was proved to promote PNH clone proliferation, which is the first time to explore the role of LncRNAs in PNH.

Abstract
Background

Iron is a nutrient essential for hemoglobin synthesis, DNA synthesis, and energy metabolism in all mammals. Iron metabolic involved in numerous types of cancers including hepatocellular cancer. In this study, we aim to identify prognostic model that based on iron metabolic-related genes that could effectively predict the prognosis for HCC patients.
Methods

The RNA microarray and clinical data of HCC patients that obtained from The Cancer Genome Atlas (TCGA) database. We identify the clusters of HCC patients with different clinical outcome performed by consensus clustering analysis. Four iron metabolic-related genes (FLVCR1, FTL, HIF1A, HMOX1) were screen for prognostic model by performed the Cox regression analysis. The efficacy of prognostic model was validated by the International Cancer Genome Consortium (ICGC) database. Meantime, the expressions value of FLVCR1, FTL, HIF1A, HMOX1 was performed using Oncomine database, the Human Protein Atlas and Kaplan Meier-plotter.
Result

The patients with low-risk score have better prognosis than high risk score both in TCGA cohort and ICGC cohort. The prognostic model showed well performance for predicting the prognosis of HCC patients than other clinicopathological parameters by OS-related ROC curves.
Conclusion

Our survival models that based on Iron metabolic can be independent risk factors for hepatocellular carcinoma patients.

Published: January 2021

Abstract
Background: Current researches about hemifacial microsomia (HFM) patients after distraction osteogenesis (DO) most emphasize the morphologic changes. This case report shows the outcome of DO on the upper airway of a HFM patient with obstructive sleep apnea (OSA) based on the use of computational fluid dynamics (CFD).Case presentation: A boy of 11-year-old was diagnosed as HFM with OSA, and underwent unilateral DO. Polysomnography and CT scans were performed before and six months after treatment. After DO, lowest blood oxygen saturation increased from 81% to 95% and apnea and hypopnea index decreased from 6.4 events/hour to 1.2 events/hour. The oropharynx and nasopharynx were obviously expanded. We observed apparently increased average pressure, decreased average velocity and pressure drop in all cross-sections, and largely decreased airflow resistance and maximum velocity entirely in the airway.Conclusions: The results suggest that DO might be effective for the treament of OSA by expanding the upper airway and reducing the resistance of inspiration.

Published: January 2021

Abstract
Background: Since the discovery of the first case of Anaplastic lymphoma kinase (ALK) -positive histiocytosis in 2008, originally described as a systemic, self-limiting disease in infants, the range of ALK-positive histiocytosis has recently been expanded to include localized diseases in older children and young adults. Case presentation: We present the case of an 18-year-old female with periumbilical painless mass for 5 months, who underwent a resection of the mass. Pathological examination showed the tumor consists predominantly of fascicular to storiform growth of nonatypical spindle cells, admixed with lymphocytic infiltrates. The tumor spindle cells were diffusely positive for CD68, CD163 and ALK. Further, molecular tests revealed ALK gene fusion: Kinesin Family Member 5B (KIF5B) (E24)-ALK (E20), confirmed ALK-positive histiocytosis. The tumor has not recurred one and a half years after resection by follow-up examination.Conclusion: ALK-positive histiocytosis in local lesion can achieve remission by complete resection and clinical follow-up showed a favorable prognosis.

Published: January 2021

Abstract
BackgroundHirschsprung’s disease (HSCR) is a congenital colon disease characterized by the lack of ganglion cells which is closely related to impaired migration and proliferation of enteric neural crest cells (ENCCs). Long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been authenticated as an important class of regulators of biological functions. In this study, a microarray analysis was conducted and found that Rhabdomyosarcoma 2-associated transcript (RMST), a newly defined lncRNA, was down-regulated in the stenotic segment of HSCR patients. MiR-1251 is transcribed from the intron region of RMST and was also low expressed in the aganglionic tract. This study aimed to clarify the roles they played in the occurrence of HSCR. MethodsQRT-PCR was applied to validate the mRNA expression of RMST, miR-1251, SOX2 and AHNAK, while western blotting was employed to evaluate the protein level of SOX2 and AHNAK in clinical samples and cells. CCK-8 and transwell assays were used to detect cell proliferation and migration after transfection. Chromatin immunoprecipitation (CHIP) was applied to confirm SOX2 could bind to the promoter region of miR-1251. RNA binding protein immunoprecipitation (RIP) was used to demonstrate the interaction between RMST and SOX2. Dul-luciferase reporter assay was performed to confirm miR-1251 could interact with AHNAK. ResultsWhen the expression of RMST or miR-1251 was reduced, cell proliferation and migration was attenuated. However, RMST not to influence the expression of miR-1251 directly. Through bioinformatic analysis, transcription factor SOX2 was predicted to bind to the promoter region of miR-1251 which was confirmed by CHIP assay. We also demonstrated that RMST exerted as a co-regulator of SOX2 via RIP assay. AHNAK was predicted as the downstream gene of miR-1251 confirmed by the dual-luciferase reporter assay. Furtherly, rescue experiments showed RMST functioned as a transcription co-regulator of SOX2 to upregulate the expression of downstream gene AHNAK by strengthening the regulation of SOX2 on miR-1251 in HSCR.ConclusionsThese findings uncovered the role of RMST/SOX2/miR-1251/AHNAK pathway during the development of Hirschsprung's disease and presented potential therapeutic targets for HSCR.

Abstract
Background: Several studies have shown that CoQ10 can rescue ovarian aging and that ovarian surface epithelium (OSE)-derived ovarian stem cells (OSCs) are useful for treating infertility with ovarian aging. However, there are few studies the effect of CoQ10 on OSCs. This study was aimed to investigate whether CoQ10 activates OSCs while recovering ovarian function using 4-vinylcyclohexene diepoxide (VCD)-induced ovarian failure mouse model.Methods: C57BL/6 female mice aged 6 weeks were randomly divided into four groups (n=10/group): (Control) saline and orally, (CoQ10) 150 mg/kg/day orally in 1 mL of saline daily for 14 days, (VCD) 160 mg/kg/day, 2.5 ml/kg ip for 5 days, (VCD+CoQ10) 5 days after VCD injection, CoQ10 (150 mg/kg/day) orally for 14 days. After final treatment of CoQ10, follicle counts were evaluated by hematoxylin and eosin (H&E) staining, and ovarian mRNA expressions of Bmp-15, Gdf-9, and c-Kit were examined by quantitative real-time PCR. Serum FSH, AMH, and ROS levels were also measured. Oocyte-like structure count and expression of Oct-4 and MVH were evaluated from postcultured OSE for 3 weeks. In the second experiment, another 32 female mice were administered with CoQ10 in the same way as above and were superovulated by PMSG and hCG, followed by mated with males. Then, numbers of zygotes ovulated and embryo development rate were examined. Results: Postcultured OSE had significantly increased numbers of oocyte-like structure and expression of Oct-4 and MVH in VCD+CoQ10 group compared to VCD group (p <0.05). Numbers of surviving follicles including from primordial to antral follicles, numbers of zygotes retrieved and embryo development rate to blastocyst were significantly higher in VCD+CoQ10 group compared to VCD group (p <0.01). Serum AMH level and ovarian expression of Bmp-15, Gdf-9, and c-Kit were significantly increased in VCD+CoQ10 group compared to VCD group (p <0.05). In contrast, serum ROS level was significantly decreased in VCD+CoQ10 group compared to VCD group (p <0.05). Conclusion(s): This is the first study to show that CoQ10 stimulates the differentiation of OSE-derived OSCs. Also this study confirms that CoQ10 can reduce ROS levels, leading to improve ovarian function and oocyte quality in ovarian failure mice.
Cascading from SARS-CoV-2 to Parkinson's Disease through Protein-Protein Interactions
Authors: Estrada Ernesto 
Published: January 2021

Abstract

Background : Extensive extrapulmonary damages in a dozen of organs/systems, including the central nervous system (CNS), are reported in patients of the coronavirus disease 2019 (COVID-19). Three cases of Parkinson's disease (PD) have been reported as a direct consequence of COVID-19. In spite of the scarce data for establishing a definitive link between COVID-19 and PD some hypothesis have been proposed to explain the cases reported. They, however, do not fit well with the clinical findings reported for COVID-19 patients in general and for the PD cases reported in particular. Given the importance of this potential connection we present here a molecular-level mechanism that explain well these findings and will serve to explore the potential CNS damage in COVID-19 patients. Methods : A model explaining the cascade effects from COVID-19 to CNS is developed by using bioinformatic tools. It includes the post-translational modification of host proteins in the lungs by viral proteins, the transport of modified host proteins via exosomes out the lungs, and the disruption of protein-protein interaction in the CNS by these modified host proteins. Results : We found 44 proteins significantly expressed in the CNS which are associated with PD and whose interactions can be perturbed by 24 host proteins significantly expressed in the lungs. These 24 perturbators are found to interact with viral proteins and to form part of the cargoes of exosomes in human tissues. The joint set of perturbators and PD-vulnerable proteins form a tightly connected network with significantly more connections than expected by selecting a random cluster of proteins of similar size from the human proteome. Conclusions : The molecular-level mechanism presented here provides several routes for the cascading of effects from the lungs of COVID-19 patients to PD. In particular, the disruption of autophagy/ubiquitination processes appears as an important mechanism that triggers the generation of large amounts of exosomes containing perturbators in their cargo, which would insult several PD-vulnerable proteins, potentially triggering Parkinsonism in COVID-19 patients.

Published: January 2021

Abstract
Background

Recently, expression of Yes-associated protein 1 (YAP1), a nuclear effector of an inactivated HIPPO pathway, has been identified as one of four molecular subtypes of SCLC defined by the predominant transcriptional regulatory mechanism. However, the clinicopathological relevance and prognostic significance of YAP1 expression in SCLC stratified by histological subtypes has not been systematically reported to date.
Methods

Tumor sections and corresponding formalin-fixed paraffin-embedded (FFPE) samples of 297 SCLC patients were retrieved from the pathological specimen repository and were subsequently reviewed by pathologists. Forty-six C-SCLCs (15.5%) and 251 P-SCLCs (84.5%) were identified respectively. YAP1 expression was examined by immunohistochemistry (IHC) and assessed semi-quantitatively on tumor tissue array (TMA). Propensity score was used to match C-SCLCs and P-SCLCs in a ratio of 1 to 2 to balance age, gender, tumor stage and treatment methods. Finally, 46 C-SCLCs and 92 P-SCLCs were included for prognostic analysis.
Results

The positive rate of YAP1 expression was significantly higher in C-SCLCs than P-SCLCs before matching (52.2% vs 29.1%, P = 0.004). After matching by propensity score, the prescribed clinical parameters were well balanced between P-SCLCs and C-SCLCs. Expression of YAP1 was associated worse overall survival (OS) (5- year OS%, 39.0% vs. 74.9%, P = 0.013) and was an independent risk factor for OS (HR = 2.93, 95% CI: 1.01–8.51; P = 0.048) exclusively in C-SCLC. Univariate survival analysis in subgroups of different clinical variables also confirmed the prognostic impact of YAP1 was most significant in C-SCLC. But for P-SCLCs, expression of YAP1 showed no prognostic impact.
Conclusions

Expression of YAP1 in small cell components of C-SCLC was significantly higher than that in P-SCLC. Besides, it served as an unfavorable predictor for OS in C-SCLC but not in P-SCLC, which suggested different entities of small cell components with variant YAP1 expression and potential different targetable oncogenic pathway between C-SCLC and P-SCLC.

Published: January 2021

Abstract
Background

Lung cancer, as one of the most lethal malignant tumors, is closely related to epithelial mesenchymal transition (EMT).
Methods

Clinical specimens and TCGA database were used to analyze the expression of MCM and HDAC1 and their impact on the survival of lung cancer patients. Cell and animal experiments are used to verify the promotion of EMT of lung cancer cells by the expression of MCM5 and HDAC1.
Results

We found that MCM5 interacts with HDAC1 and promotes the EMT-mediated malignant progression of lung cancer. Lung adenocarcinoma patients with high expression of MCM5 and HDAC1 have poor survival time. Overexpression of MCM5 and HDAC1 in A549 and H1975 cells can promote metastasis and invasion in vitro and tumor growth and metastasis in vivo. Moreover, astragaloside IV can block the interaction of HDAC1 and MCM5, which can then inhibit the malignant progression of lung cancer in vivo and in vitro.
Conclusion

We described the interaction of MCM5 and HDAC1 to promote the EMT-dependent malignant progression in lung cancer. Astragaloside IV inhibited lung cancer progression by blocking the combination of MCM5 and HDAC1.
