Gastric varices (GV) are present in around 20% of patients with cirrhosis. Bleeding from GV accounts for 10-20% of all variceal bleeding. GV are classified according to their location in the stomach and their relationship with esophageal varices (EV). Accordingly, GV are divided into gastroesophageal varices (GOV) and isolated gastric varices (IGV) . The management of type 1 GOV, which extend from the esophagus along the lesser curvature of the stomach, is similar to the management of EV. Historically, bleeding from type 2 GOV (i.e. GOV extending into the fundus), type 1 IGV (i.e. located in the fundus) and type 2 IGV (i.e. located anywhere in the stomach), is considered to be more severe and difficult to treat than EV bleeding. Few studies, mostly retrospective and uncontrolled, have focused on the management of non-GOV1 GV, and the optimal treatment remains controversial.

For the prevention of gastric variceal bleeding, treatment principles can be classified into two categories: decreasing portal pressure and obstructing GEV. Methods for decreasing portal pressure include medications (NSBB), radiological intervention (TIPS) and surgery. In contrast, methods for treating the obstruction of GEV include endoscopic approaches (EVL, EIS) or radiological intervention (such as BRTO). Recent portal hypertensive bleeding suggested TIPS or BRTO as firstline treatments in the prevention of rebleeding.

BRTO is a procedure for treatment of fundal varices associated with a large gastro-/splenorenal collateral. The technique involves retrograde cannulation of the left renal vein by the jugular or femoral vein, followed by balloon occlusion and slow infusion of sclerosant to obliterate the gastro-/splenorenal collateral and fundal varices. Several variations of the technique exist, such as balloon-occluded antegrade transvenous obliteration or occlusion of the collateral by the placement of a vascular plug or coils. BRTO has the theoretical advantage over TIPS that it does not divert portal blood inflow from the liver. On the other hand, BRTO and its variations might increase portal pressure and might worsen complications, such as ascites or bleeding from EV. In this regard, if NSBB is combined with BRTO and its variations (we called interventional devascularization) for those HVPG responders, the drawbacks of interventional devascularization might be overcome.

Therefore, the investigators conducted this RCT to compare the effectiveness and safety of TIPS with those of interventional devascularization in the prevention of rebleeding from gastric varices.
BACKGROUND: Renal function after left renal vein (LRV) ligation following en bloc resection of segmental inferior vena cava (IVC) and right kidney is understudied. We assessed the impact of LRV ligation on postoperative renal function following en bloc resection of segmental IVC and right kidney.
METHODS: We retrospectively reviewed 28 patients who underwent LRV ligation during en bloc resection of segmental IVC and right kidney. Patient demographics, tumor characteristics, intraoperative factors, complications, length of hospital and intensive care unit (ICU) stay, and patient survival were collected. Pre- and postoperative renal function was retrospectively analyzed.
RESULTS: Twenty patients underwent robot-assisted surgery and eight patients underwent open surgery. The median operative time was 162 min and estimated blood loss was 350 mL. Ten patients had normal renal function and 12 patients had an initial increase in creatinine but improved gradually. Six patients developed acute renal failure; five patients gradually recovered in 5-32 days after temporary hemodialysis. Renal replacement therapy significantly correlated with maximal anterior-posterior diameter of the LRV (p = 0.001). Complications were observed in 11 cases, four of which were Clavien-Dindo grades I-II. Thirteen patients were alive with no recurrence, nine patients were alive with metastasis, and six cases died during the follow-up period.
CONCLUSIONS: LRV ligation following en bloc resection of segmental IVC and right kidney is feasible, with no significant long-term impact on renal function. The maximum anterior-posterior diameter of the LRV is a reliable method for predicting renal replacement therapy in the absence of collateral circulation.
The invention relates to an anti-HIV gene engineering recombinant virus and a preparation method thereof, and an anti-HIV gene engineering medicament. The anti-HIV gene engineering recombinant virus comprises a constant region of a human antibody, and a cluster of differentiation 4 (CD4) and a chemokine receptor 5 (CCR5) which are connected with the constant region. The preparation method for the anti-HIV gene engineering recombinant virus comprises the steps as follows: obtaining a heavy chain constant region gene of the human antibody, a light chain constant region gene of the human antibody, a CD4 gene and a CCR5 gene; constructing a virus vector shuttle plasmid comprising the four genes; co-transforming the shuttle plasmid and a virus auxiliary plasmid to generate a recombinant virus plasmid; and transferring the recombinant virus plasmid to a cell strain for culturing and purifying the virus. The recombinant virus has both the CD4 and CCR5 capable of specifically binding with the CD4 site and CCR5 site of an HIV virus, an obviously enforced specific binding effect, and the function of doubly preventing the HIV virus from infecting a host cell. The preparation method is simple and practical. The anti-HIV gene engineering medicament with the recombinant virus can effectively act on the HIV virus, and can further effectively prevent and treat the infection of the HIV virus.

Osteoarthritis (OA) is a common degenerative joint disease which currently lacks of effective agents. It is therefore urgent and necessary to seek an effective approach that can inhibit inflammation and promote cartilage matrix homeostasis. Cartilage progenitor cells (CPCs) are identified as a cell population of superficial zone in articular cartilage which possess strong migration ability, proliferative capacity, and chondrogenic potential. Recently, the application of CPCs may represent a novel cell therapy strategy for OA treatment. There is growing evidence that extracellular vesicles (EVs) are primary mediators of the benefits of stem cell-based therapy. In this study, we explored the protective effects of CPCs-derived EVs (CPCs-EVs) on IL-1β-induced chondrocytes. We found CPCs-EVs exhibited chondro-protective effects in vitro. Furthermore, our study demonstrated that CPCs-EVs promoted matrix anabolism and inhibited inflammatory response at least partially via blocking STAT3 activation. In addition, liquid chromatography-tandem mass spectrometry analysis identified 991 proteins encapsulated in CPCs-EVs. By bioinformatics analysis, we showed that STAT3 regulatory proteins were enriched in CPCs-EVs and could be transported to chondrocytes. To promoting the protective function of CPCs-EVs in vivo, CPCs-EVs were modified with cationic peptide ε-polylysine-polyethylene-distearyl phosphatidylethanolamine (PPD) for surface charge reverse. In posttraumatic OA mice, our results showed PPD modified CPCs-EVs (PPD-EVs) effectively inhibited extracellular matrix catabolism and attenuated cartilage degeneration. Moreover, PPD-EVs down-regulated inflammatory factors expressions and reduced OA-related pain in OA mice. In ex-vivo cultured OA cartilage explants, PPD-EVs successfully promoted matrix anabolism and inhibited inflammation. Collectively, CPCs-EVs-based cell-free therapy is a promising strategy for OA treatment.
PROBLEM TO BE SOLVED: To obtain an antimycotic agent for external use having antimycotic activity and excellent safety by compounding a nucleic acid. SOLUTION: A nucleic acid composed of DNA and RNA is added to an agent in an amount of preferably 1.5-25%. The nucleic acid is extracted from a living matter such as animal, plant, bacteria and fungi by conventional method. The animal is e.g. pig, horse, cattle, sheep, chicken or fish, the plant is e.g. wood, vegetable or algae and the bacteria and fungi are e.g. lactic bacteria, Bacillus subtilis, Escherichia coli, beer yeast or aspergillus. Preferable nucleic acid is extracted from the soft roe of fish. The agent for external use compounded with a nucleic acid can be produced by compounding a chemically synthesized antimycotic agent (tolnaftate, ciclopirox olamine, salicylic acid, butenafin hydrochloride and croconazole hydrochloride).
Patients will begin by collecting data at home without using the mobilaser. They will then be given the mobilaser to use at home for 6 weeks while they collect data on whether their gait has improved. They will then have to return the Mobilaser to the clinic and collect data at home for 3 days to see if there is a difference.
Recognizing non-invasive growth patterns is necessary for correct diagnosis, invasive size determination and pT-stage in resected non-small cell lung carcinoma. Due to iatrogenic collapse after resection, the distinction between adenocarcinoma in-situ (AIS) and invasive adenocarcinoma may be difficult. The aim of this study is to investigate the complex morphology of non-mucinous non-invasive patterns of AIS in resection specimen with iatrogenic collapse, and to relate this to follow-up. The effects of iatrogenic collapse on the morphology of collapsed AIS were simulated in a mathematical model. Three dimensional related criteria applied in a modified classification, using also cytokeratin 7 and elastin as additional stains, in two independent retrospective cohorts of primary pulmonary adenocarcinomas ≤3 cm resection specimen with available follow-up information. The model demonstrated that infolding of alveolar walls occurs during iatrogenic collapse and lead to a significant increase in tumor cell heights in maximal collapse areas, compared to less collapsed areas. The morphology of infolded AIS overlaps with patterns described as papillary and acinar adenocarcinoma according to the WHO classification, necessitating an adaptation. The modified classification incorporates recognition of iatrogenic and biologic collapse, tangential cutting effect true invasion and surrogate markers of invasion i.e. grey zone, covering a multilayering falling short of micropapillary, cribriform and solid alveolar filling growth. The use of elastin and CK7 staining aids in the morphologic recognition of iatrogenic collapsed AIS and the distinction from invasive adenocarcinoma. Out of a total of 70 resection specimens 1 case was originally classified as AIS and 9 were reclassified as iatrogenic collapsed AIS. Patients with collapsed AIS showed a 100 % recurrence-free survival after a mean follow-up time of 69.5 months. With the current WHO classification, AIS is overdiagnosed as invasive adenocarcinoma due to infolding. The modified classification facilitates the diagnosis of AIS.
ETHNOPHARMACOLOGICAL RELEVANCE: In the progression of chronic liver diseases, liver fibrosis is a reversible pathophysiologic event for liver diseases prognosis and risk of cirrhosis. Liver injury factors of different etiologies mediate this process. There is still a lack of effective medications for treating liver fibrosis. Additionally, the ameliorative effects of traditional herbs on liver fibrosis have been commonly reported. Tianhuang formula (THF) is a drug combination consisting of 2 traditional Chinese herbs, which has been showing significant improvement in metabolic liver diseases. However, the hepatoprotective effect and mechanism of THF in ameliorating liver fibrosis are still unclear.
AIM OF THE STUDY: This study aimed to investigate the effects of THF on carbon tetrachloride (CCl4)-induced and methionine-choline-deficient (MCD) diet-induced liver fibrosis model and to reveal the potential mechanisms. It can provide experimental evidence for THF as a therapeutic candidate for liver fibrosis.
MATERIALS AND METHODS: In this study, CCl4-induced mice were treated with THF (80 mg/kg, 160 mg/kg) or Fuzheng Huayu (FZHY) capsules (4.8 g/kg) for 6 weeks. MCD-induced mice received the same doses of THF or FZHY for 4 weeks. FZHY is used as a comparative study in these two models. Following that, using kit reagents detected changes in relevant serum and liver biochemical indicators. Histological changes in mouse liver were measured by staining of H&E and Sirius Red. The markers expression of liver fibrosis and inflammation were detected using qRT-PCR, western blotting and immunohistochemical staining analysis. The potential regulatory mechanism of THF to ameliorate liver fibrosis was performed by RNA-sequencing analysis. Finally, the analysis results were verified by immunofluorescence co-staining, qRT-PCR and western blotting.
RESULTS: Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and hepatic triglyceride (TG) levels in CCl4 and MCD-induced liver fibrosis mice were significantly improved after THF treatment. Meanwhile, the expression of fibrosis and inflammation markers were significantly suppressed. Furthermore, THF downregulated the expression of the macrophage marker CD68. According to RNA-sequencing analysis, we found the CCL2-CCR2 axis and MAPK/NF-κB as the potential signaling pathway for THF against liver fibrosis.
CONCLUSION: This study revealed that THF ameliorated liver injury, inflammation and fibrotic process by inhibiting CCL2-CCR2 axis and its downstream MAPK/NF-κB signaling pathway.

OBJECTIVES: Severe pulmonary complications such as postoperative respiratory failure can occur after minimally invasive oesophagectomy. However, the risk factors have not been well identified. The goal of this study was to develop a predictive model for the occurrence of postoperative respiratory failure with a large sample.
METHODS: We collected data from patients with oesophageal cancer who had a minimally invasive oesophagectomy at Shanghai Chest Hospital from 2019 to 2022. Univariable and backward stepwise logistic regression analysis of 19 pre- and intra-operative factors was used before model fitting, and its performance was evaluated with the receiver operating characteristic curve. Internal validation was assessed with a calibration plot, decision curve analysis and area under the curve with 95% confidence intervals, obtained from 1000 resamples set by the bootstrap method.
RESULTS: This study enrolled 2,386 patients, 57 (2.4%) of whom developed postoperative respiratory failure. Backward stepwise logistic regression analysis revealed that age, body mass index, cardiovascular disease, diabetes, diffusion capacity of the lungs for carbon monoxide, tumour location and duration of chest surgery ≥101.5 min were predictive factors. A predictive model was constructed and showed acceptable performance (area under the curve: 0.755). The internal validation with the bootstrap method proves the good agreement for prediction and reality.
CONCLUSIONS: Obesity, severe diffusion dysfunction and upper segment oesophageal cancer were strong predictive factors. The established predictive model has acceptable predictive validity for postoperative respiratory failure after minimally invasive oesophagectomy, which may improve the identification of high-risk patients and enable health-care professionals to perform risk assessment for postoperative respiratory failure at the initial consultation.

The pathology of medication-related osteonecrosis of the jaw (MRONJ), often associated with antiresorptive therapy, is still not fully understood. Osteocyte networks are known to play a critical role in maintaining bone homeostasis and repair, but the exact condition of these networks in MRONJ is unknown. On the other hand, the local application of E-coli-derived Recombinant Human Bone Morphogenetic Protein 2/β-Tricalcium phosphate (E-rhBMP-2/β-TCP) has been shown to promote bone regeneration and mitigate osteonecrosis in MRONJ-like mouse models, indicating its potential therapeutic application for the treatment of MRONJ. However, the detailed effect of BMP-2 treatment on restoring bone integrity, including its osteocyte network, in an MRONJ condition remains unclear. Therefore, in the present study, by applying a scanning electron microscope (SEM) analysis and a 3D osteocyte network reconstruction workflow on the alveolar bone surrounding the tooth extraction socket of an MRONJ-like mouse model, we examined the effectiveness of BMP-2/β-TCP therapy on the alleviation of MRONJ-related bone necrosis with a particular focus on the osteocyte network and alveolar bone microstructure (microcrack accumulation). The 3D osteocyte dendritic analysis showed a significant decrease in osteocyte dendritic parameters along with a delay in bone remodeling in the MRONJ group compared to the healthy counterpart. The SEM analysis also revealed a notable increase in the number of microcracks in the alveolar bone surface in the MRONJ group compared to the healthy group. In contrast, all of those parameters were restored in the E-rhBMP-2/β-TCP-treated group to levels that were almost similar to those in the healthy group. In summary, our study reveals that MRONJ induces osteocyte network degradation and microcrack accumulation, while application of E-rhBMP-2/β-TCP can restore a compromised osteocyte network and abrogate microcrack accumulation in MRONJ.
BACKGROUND: Laparoscopic appendectomy has gained prominence in the management of acute appendicitis, necessitating secure closure of the appendiceal stump. Two common techniques for this purpose are Hem-o-lok clips (HC) and endoloops (EL), each offering distinct advantages.
AIMS: This retrospective study aimed to compare the outcomes of the HC and EL closure techniques. Specifically, the study focused on postoperative complications, hospital stays, and readmission rates.
MATERIALS AND METHODS: A retrospective database review was conducted from November 2022 to August 2023. The study compared outcomes, postoperative complications, and the length of hospital stay in 123 patients who underwent appendiceal stump closure with HC and EL at the General Surgery Department of the Turkish Hospital in Doha, Qatar.
RESULTS: Among the 123 patients who underwent laparoscopic appendectomy, appendiceal stump closure was performed with HC in 50 patients and EL in 73 patients. Six patients experienced infectious complications associated with the procedure. The hospital stays were similar in both groups (Group HC: 1.3 ± 2 days, Group EL: 1.4 ± 2 days), and there were two readmissions in each group.  Conclusion: The study supports the equivalence of HC and EL closure techniques. Both methods demonstrate comparable postoperative complications, hospital stays, and readmission rates. Surgeons can make informed decisions based on patient profiles and available resources.
