G. rigescens Franch (Long Dan Cao in Chinese) is a well-known TCM herb. It is clinically used with other drugs for the treatment of brain diseases such as epilepsy, postherpetic neuralgia in China.', 'In our previous study, the 11 dihydroxybenzoates compounds with NGF mimicking activity from G. rigescens Franch were found. In the present study, the neurogenesis and neuroprotection of a mixture of benzoates (\xa0n-GS) were investigated in animal level.', 'The NGF mimicking activity of n-GS from G. rigescens Franch was examined in PC12 cells. The neurogenesis effects of n-GS were investigated in ICR mice with 5-bromo-2-deoxyuridine (BrdU) and neuronal neclei (NeuN) double immunostaining. Furthermore, the neuroprotection effects of n-GS on the memory in a scopolamine (SCO)-induced mouse model were evaluated with animal behavior tests.', "The NGF-mimicking function and neurogenesis of n-GS were observed in PC12 cells and in normal mice. Subsequently, we investigated the effects of n-GS on the memory in a SCO-induced mouse model. In Y-maze test, SCO significantly lowered the alternation. This finding was reversed by n-GS and donepezil (DONE). SCO significantly impaired the mice's performance in novel object recognition (NOR) and Morris water maze (MWM) tests. The time spent to explore the novel object was longer in the n-GS- and DONE-treated groups than in the SCO control group. In the MWM test, the escape latency of n-GS- and DONE-treated groups was shorter than that of the SCO control group. Mechanism study showed that SCO significantly reduced superoxide dismutase (SOD) but increased the activities of acetylcholinesterase (AChE) and the levels of malondialdehyde (MDA) in the hippocampus and cerebral cortex, which all can be improved by n-GS and DONE. Additionally, the phosphorylation of type 1 insulin-like growth factor (IGF-1) receptor, extracellular signal-regulated kinase (ERK), and cAMP responsive element-binding (CREB) protein in the hippocampus was significantly up-regulated in the treatment group compared with that in the SCO group.

To describe the prevalence of prolonged fatigue, chronic fatigue syndrome (CFS)-like illness, and associated symptom patterns in adolescents attending primary care.', 'The design was cross-sectional. A questionnaire designed by the authors assessing fatigue and associated symptoms was administered to 901 adolescents (aged 11-18 years) attending 12 primary care clinics in the Chicago area. Prevalence rates for prolonged fatigue and CFS-like illness were calculated. Univariate comparisons involving sociodemographic data and fatigue severity were made between adolescents with and without prolonged fatigue, and sociodemographic and symptom predictors of prolonged fatigue were identified using logistic regression analysis.', 'Prolonged fatigue (> or = 1 month) occurred at a rate of 8.0% and CFS-like illness occurred at a rate of 4.4%. Adolescents with prolonged fatigue were significantly older and also reported greater fatigue severity than those without fatigue. Findings from logistic regression indicated that, in addition to increasing age, headaches, muscle pains, fever, and fatigue made worse by exercise were significantly associated with prolonged fatigue.

There is well-known inter-individual variability in the cholesterol-lowering effect of statins. However, inter-individual variability in response to rosuvastatin treatment in subjects with hypercholesterolemia has not been clearly established. This study aimed to evaluate the associations of CYP2C9 genetic polymorphism with the efficacy and safety of rosuvastatin in Chinese patients with hyperlipidemia.', 'A total of 218 patients with hyperlipidemia were selected and treated with 10 mg rosuvastatin per day for 12 weeks. Blood samples were collected prior to the treatment and after 4, 8, and 12 weeks of treatment. Clinical biochemistry analyses for serum lipid profiles were performed. Genotyping for CYP2C9 polymorphisms was performed using allele-specific real-time PCR.', '197 out of 218 patients featured a wild-type CYP2C9*1/*1 genotype, and 21 patients featured a CYP2C9*1/*3 or CYP2C9*3/*3 mutation genotype. No patients with CYP2C9*2 alleles were identified. Sixteen patients discontinued the medication due to adverse effects. No serious adverse events (i.e., hepatotoxicity or myolysis) were observed. After the 12 weeks of treatment, we observed significant reductions in total cholesterol (TC), triglycerides and low-density lipoprotein (LDL) levels compared to baseline (p < 0.05). Patients with the mutant genotype showed a higher TC-lowering and LDL-lowing effect compared to those with wild-type genotypes (TC: 45.05% vs. 38.96%, p = 0.041; LDL: 44.97% vs. 39.28%, p = 0.029). The frequency of adverse drug reactions in the studied patients did not differ by CYP2C9 genotypes (p > 0.05).
