OBJECTIVE To explore the efficacy of Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction on adult chronic insomnia and its effect on hypnotic withdrawal.METHODS 187 patients with chronic insomnia were included for anal-ysis,including 102 in the traditional Chinese medicine(TCM)group and 85 in the western medicine group.The TCM group was trea-ted with Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction,while the western medicine group was treated with benzodiazepine under the consideration of doctor.The intervention period was 1 month,with assessments using the Pittsburgh Sleep Quality Index(PSQI)conducted before and after the intervention.Follow-up evaluations were performed at 3 months and 6 months re-spectively after the intervention.RESULTS There was no significant difference between the two groups at baseline.After the inter-vention,the PSQI scores of patients in both groups were significantly improved(P<0.01).Among them,the TCM group was better than the western medicine group in the improvement of sleep quality and sleeping pills,total PSQI score reduction(P<0.01).The re-sults of linear regression analysis showed that after controlling for confounding factors,the regression coefficients of the TCM group in two different models were1.821 and 1.922 respectively,and the former was statistically significant(P<0.05).By screening patients who took hypnotics at baseline in the TCM group and comparing them with those in the western medicine group,the influencing factors of hypnotic withdrawal were analyzed.During the 3-month follow-up,25 out of 39 patients in the TCM group and 17 out of 80 patients in the western medicine group had hypnotic withdrawal(χ2= 19.25,P<0.001);during the 6-month follow-up,23 of the 39 patients in the TCM group and 18 of the 79 patients in the western medicine group had hypnotic withdrawal(χ2= 13.53,P<0.001),the with-drawal rate of patients in the TCM group was significantly higher than that in the western medicine group.Further regression analysis showed that after adjusting for confounding factors,the results showed that the western medicine group had a significantly higher rate of not withdrawal than the TCM group at 3 months(OR=5.50,95%CI:2.30～13.72)and 6 months(OR=6.43,95%CI:2.54～17.77),and the results were statistically different(P<0.05).CONCLUSION Sour Jujube Seed Decoction combined with Huangli-an Wendan Decoction is effective in treating adult chronic insomnia and assisting in hypnotic withdrawal.

This study aims to investigate the mechanism of Linderae Radix water extract(LRWE) in the prevention and treatment of diarrhea-predominant irritable bowel syndrome(IBS-D) based on serum metabolomics. Eighteen 2-week-old male SD rats were randomized into control, IBS-D model, and LRWE groups. The rats in other groups except the control group received gavage of senna concentrate combined with restraint stress for the modeling of IBS-D. The rats in the LRWE group were administrated with LRWE(5.4 g·kg~(-1)) by gavage, and those in the control and IBS-D model groups with an equal volume of distilled water for a total of 14 days. The visceral sensitivity was evaluated by the abdominal withdrawal reflex(AWR) score, and the degree of diarrhea was assessed by the fecal water content(FWC). The morphological changes of the colon and the morphology and number of goblet cells were observed by hematoxylin-eosin(HE) and periodic acid-schiff(PAS) staining, respectively. Ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) was used for the screening of the potential biomarkers in the rat serum and their related metabolic pathways. The results showed that LRWE reduced the AWR score, decreased FWC, and alleviated visceral sensitivity and diarrhea symptoms in IBS-D rats. HE and PAS staining showed that LRWE mitigated low-grade intestinal inflammation and increased the number of mature secretory goblet cells in the colonic epithelium of IBS-D rats. A total of 25 potential biomarkers of LRWE in treating IBS-D were screened out in this study, which were mainly involved in riboflavin, tryptophan, glycine, serine and threonine metabolism, glyoxylate and dicarboxylate metabolism, and cysteine and methionine metabolism. The regulatory effects were the most significant on the riboflavin and tryptophan metabolism pathways. LRWE may alleviate the visceral hypersensitivity by promoting energy metabolism and amino acid metabolism, enhancing intestinal barrier function, and improving intestinal immune function in IBS-D rats.

RNA modifications affect many biological processes and physiological diseases. The 5-methylcytosine (m⁵C) modification regulates the progression of multiple tumors. However, its characteristics and functions in hepatocellular carcinoma (HCC) remain largely unknown. Here, we found that HCC tissues had a higher m⁵C methylation level than the adjacent normal tissues. Transcriptome analysis revealed that the hypermethylated genes mainly participated in the phosphokinase signaling pathways, such as the Ras and PI3K-Akt pathways. The m⁵C methyltransferase NSUN2 was highly expressed in HCC tissues. Interestingly, the expression of many genes was positively correlated with the expression of NSUN2, including GRB2, RNF115, AATF, ADAM15, RTN3, and HDGF. Real-time PCR assays further revealed that the expression of the mRNAs of GRB2, RNF115, and AATF decreased significantly with the down-regulation of NSUN2 expression in HCC cells. Furthermore, NSUN2 could regulate the cellular sensitivity of HCC cells to sorafenib via modulating the Ras signaling pathway. Moreover, knocking down NSUN2 caused cell cycle arrest. Taken together, our study demonstrates the vital role of NSUN2 in the progression of HCC.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

Increased neuronal apoptosis is an important pathological feature of Alzheimer's disease (AD). The Bcl-2-interacting mediator of cell death (Bim) mediates amyloid-beta (Aβ)-induced neuronal apoptosis. Naturally-occurring antibodies against Bim (NAbs-Bim) exist in human blood, with their levels and functions unknown in AD. In this study, we found that circulating NAbs-Bim were decreased in AD patients. Plasma levels of NAbs-Bim were negatively associated with brain amyloid burden and positively associated with cognitive functions. Furthermore, NAbs-Bim purified from intravenous immunoglobulin rescued the behavioral deficits and ameliorated Aβ deposition, tau hyperphosphorylation, microgliosis, and neuronal apoptosis in APP/PS1 mice. In vitro investigations demonstrated that NAbs-Bim were neuroprotective against AD through neutralizing Bim-directed neuronal apoptosis and the amyloidogenic processing of amyloid precursor protein. These findings indicate that the decrease of NAbs-Bim might contribute to the pathogenesis of AD and immunotherapies targeting Bim hold promise for the treatment of AD.

Objective:To systematically evaluate the efficacy and safety of neoadjuvant chemoradiotherapy (NCRT) plus surgery versus neoadjuvant chemotherapy (NCT) plus surgery in the treatment of advanced esophageal squamous cell carcinoma.Methods:Clinical controlled trials of comparing the treatment of NCRT plus surgery with NCT plus surgery for esophageal squamous cell carcinoma were electronically searched from the databases including PubMed, The Cochrane Library, EMbase, CBM, CNKI, WanFang and VIP from the inception of databases to January, 2019. Two reviewers independently screened the literatures, extracted data and assessed the risk of bias of the included studies. And then, a meta-analysis was performed by using RevMan 5.3 software.Results:A total of 8 clinical control studies were included, including 995 patients with esophageal squamous cell carcinoma. Meta-analysis results showed that compared with the NCT group, the R 0 resection rate was significantly higher ( OR=2.14, 95% CI: 1.03-4.45, P=0.040) and the pathological complete response (pCR) rate was significantly higher ( OR=4.19, 95% CI: 1.71-10.28, P=0.002) in the NCRT group. The incidence of postoperative complications ( OR=1.37, 95% CI: 0.76-2.48, P=0.300) and the risk of perioperative death ( OR=1.28, 95% CI: 0.58-2.83, P=0.54) were not significantly different between two groups. The long-term survival of patients with esophageal squamous cell carcinoma in the NCRT group was significantly better compared with that in the NCT group ( HR=0.77, 95% CI: 0.64-0.92, P=0.005). Conclusions:Compared with NCT plus surgery for advanced esophageal squamous cell carcinoma, NCRT plus surgery has higher R 0 resection rate and pCR rate, does not significantly increase the risk of perioperative complications or perioperative death, and significantly improves the long-term survival of esophageal squamous cell carcinoma patients.

Objective:From a new perspective，to explore therapeutic effect of Huidouba (HDB) on alleviating kidney oxidative damage in rats with diabetic nephropathy (DN) and provide a scientific basis for developing HDB as a potential Tibetan medicine for treatment of DN. Method:Rats were fed with high-fat diet (HFD) and injected with streptozocin (STZ, 65 mg·kg^-1) intraperitoneally to induce DN model, while rats in Blank group were injected with an equal volume of vehicle and fed with normal chow. The successfully modeling DN rats were randomly divided into three groups, 8 rats per group, DN model group (10 mL·kg^-1·d^-1), Metformin group (0.045 g·kg^-1·d^-1) and HDB group (0.18 g·kg^-1·d^-1). Monitor body weight (BW) and fasting blood glucose (FBG) weekly, and collect 24 hours urine before and after medication to examine microalbuminuria (mAlb). Calculate kidney index (KI) after sacrificing, analyze mAlb, serum creatinine (SCr) and blood urea nitrogen (BUN) with a fully automatic biochemical analyzer. Histopathology of kidney was observed by Masson staining. Lipid peroxidation malondialdehyde (MDA) assay kit was used to examine MDA content in kidney tissue. Nox4, as a subtype of triphosphopyridine nucleotide (NADPH) oxidase family was determined by Western blot and immunofluorescence assay of kidney tissue. Result:Compared with blank group, levels of FBG, 24 h mAlb, SCr, BUN and MDA in DN model group were increased (P<0.01), tissue damage was obvious and Nox4 expression in glumeruli was increased significantly (P<0.01). Compared with DN model group, levels of FBG, 24 h mAlb, SCr, BUN and MDA in drug administration groups were decreased (P<0.01), kidney injury was alleviated and Nox4 expression was down-regulated（P<0.01）. Conclusion:HDB as a Yiqiyangyin Tibetan medicine, could ease oxidative stress injury of kidney and reduce proteinuria in DN rats, thus prevent the development of DN. Its mechanism is closely related to down-regulating Nox4 expression of kidney tissue in DN rats.
