OBJECTIVES: To investigate the relationship between the polygenic risks for various psychiatric disorders and clinical and neuropsychological characteristics in children with attention-deficit/hyperactivity disorder (ADHD). METHODS: Using a cross-sectional design, 285 children with ADHD and 107 healthy controls were assessed using the Child Behavior Checklist, the Behavior Rating Inventory of Executive Function for parents, the Wechsler Intelligence Scale for Children, Fourth Edition, and the Cambridge Neuropsychological Test Automated Battery. Blood samples were collected for genetic data. Polygenic risk scores (PRSs) for various psychiatric disorders were calculated using the PRSice-2 software. RESULTS: Compared with the healthy controls, the children with ADHD displayed significantly higher PRSs for ADHD, major depressive disorder, anxiety disorder, and obsessive-compulsive disorder (P<0.05). In terms of daily-life executive function, ADHD-related PRS was significantly correlated with the working memory factor; panic disorder-related PRS was significantly correlated with the initiation factor; bipolar disorder-related PRS was significantly correlated with the shift factor; schizophrenia-related PRS was significantly correlated with the inhibition, emotional control, initiation, working memory, planning, organization, and monitoring factors (P<0.05). The PRS related to anxiety disorders was negatively correlated with total IQ and processing speed index (P<0.05). The PRS related to obsessive-compulsive disorder was negatively correlated with the processing speed index and positively correlated with the stop-signal reaction time index of the stop-signal task (P<0.05). CONCLUSIONS PRSs for various psychiatric disorders are closely correlated with the behavioral and cognitive characteristics in children with ADHD, which provides more insights into the heterogeneity of ADHD.

ObjectiveTo explore the mechanism by which Zuoguiwan improves the pancreas development in the gestational diabetes mellitus （GDM） model by observing the effects of Zuoguiwan on the expression of key regulatory factors in different stages of pancreas development. MethodsPregnant Wistar rats were randomly assigned into blank， model， insulin detemir （20 U·kg^-1） and Zuoguiwan （1.89 g·kg^-1） groups （n=18）. GDM was induced by peritoneal injection of streptozotocin on day 6.5 （E6.5d） in the embryonic stage， and the blank group was given an equal volume of sodium citrate buffer. The modeling performance was assessed by measuring the blood glucose of pregnant rats. Except the blank group and model group， pregnant rats in other groups were administrated with corresponding drugs from E9.5d to delivery. The random blood glucose of pregnant rats was monitored， and the embryos and offspring rats were measured for the length and weighed on E12.5d， E18.5d and day 21 after birth （B21d）. The Lee's index of rats on B21d was calculated. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the fasting insulin （FINS） levels of B22d rats and the Homeostasis Model Assessment for Insulin Resistance （HOMA-IR） was calculated. The serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， total bilirubin （TBIL）， total cholesterol （CHO）， triglyceride （TG）， high-density lipoprotein cholesterol （HDL）， and low-density lipoprotein cholesterol （LDL） in E18.5d pregnant rats and B22d offspring were determined. The pathological changes in the pancreas of E12.5d， E18.5d and B22d rats were observed by hematoxylin-eosin （HE） staining. Western blot was used to determine the protein levels of pancreatic duodenal homeobox 1 （Pdx1）， pancreas-specific transcription factor 1a （Ptf1a）， and sex-determining region Y-box protein 9 （Sox9） in the pancreas of E12.5d embryos， Pdx1， Nkx2 homeobox 2 （Nkx2.2）， and hairy and enhancer of split-1 （Hes1） in the pancreas of E18.5d embryos， and Pdx1， v-maf musculoaponeurotic fibrosarcoma oncogene homolog A （Mafa）， and NK transcription factor-related homeobox gene family 6 locus 1 （Nkx6.1） in the pancreas of B22d rats. ResultsCompared with the blank group， the model group showed elevated blood glucose levels in pregnant rats on B0d， E9.5d， E12.5d， E15.5d， and E18.5d （P<0.05， P<0.01）， decreased body weight and body length （P<0.01） and increased Lee's index in the offspring. In addition， the B22d offspring showed rising levels of FBG， FINS， HOMA-IR， AST， and TG （P<0.01）， a declined level of HDL （P<0.01）， and pancreatic acinous cells with edema and loose arrangement. The pregnant rats on E18.5d exhibited raised levels of ALT， AST， and TG （P<0.05， P<0.01） in the pancreas and a declined level of HDL （P<0.05）. The E12.5d embryos showed up-regulated protein levels of Pdx1， Sox9， and Ptf1a in the pancreas （P<0.01） and the E18.5d embryos exhibited down-regulated protein levels of Pdx1， Nkx2.2， and Hes1 in the pancreas （P<0.01）. The protein levels of Pdx1， Nkx6.1， and Mafa in the pancreas of B22d offspring were down-regulated （P<0.01）. Compared with the model group， the insulin group exhibited lowered blood glucose in pregnant rats on B0d， E15.5d， and E18.5d （P<0.05， P<0.01）. The offspring in all treatment groups showcased increased body weight and body length （P<0.01） and decreased Lee's index. The B22d offspring exhibited declined levels of FBG， FINS， and HOMA-IR in the insulin group （P<0.01） and lowered levels of FBG and HOMA-IR in the Zuoguiwan group （P<0.01）. The B22d offspring in all the treatment groups showed reduced levels of ALT， AST， TBIL， CHO， TG， and LDL， a raised level of HDL， and alleviated edema of pancreatic acinous cells. The pregnant rats on E18.5d demonstrated declined levels of TG and ALT （P<0.05， P<0.01） and an elevated level of HDL （P<0.05）. The pancreas of E12.5d embryos presented down-regulated protein levels of Pdx1 and Sox9 and an up-regulated protein level of Ptf1a in the insulin group （P<0.05）. The pancreas of E12.5d embryos in the Zuoguiwan group presented down-regulated protein levels of Pdx1， Sox9， and Ptf1a （P<0.01）. All the treatment groups showed up-regulated protein levels of Pdx1， Nkx2.2， and Hes1 in the pancreas of E18.5d embryos （P<0.01） and Pdx1， Nkx6.1， and Mafa in the pancreas of B22d embryos （P<0.05， P<0.01）. ConclusionZuoguiwan can promote the growth and development and ameliorate the pathological changes in the pancreas of the offspring of GDM model by regulating the expression of Pdx1 pathway-related regulatory factors in different stages of pancreas development.

Objective:To systematically evaluate the effect of the Dietary Approaches to Stop Hypertension (DASH) diet on common metabolic diseases.Methods:Following the PICOS framework to construct the search formula, we systematically searched the Web of science, PubMed, Cochrane Library, CNKI, Wanfang, and VIP databases for randomized controlled trials (RCTs) investigating the effect of the DASH diet on multiple metabolic indices including body weight, body mass index (BMI), fasting blood glucose, triglycerides, systolic blood pressure (SBP), and diastolic blood pressure (DBP) in patients with metabolic disorders (e.g., obesity, diabetes mellitus, and hypertension) published both in China and abroad from 1 January 2000 to 31 December 2023. The search terms were combinations of MeSH and free-text terms, and the raw data obtained from the search were screened according to the inclusion and exclusion criteria to determine the articles that were finally included in the analysis. The differences in these metabolic indices were compared between the intervention group group (using DASH diet) and the control group. The quality of the studies was assessed quantitatively using the modified Jadad scale and qualitatively using the Risk of Bias 2 (RoB 2) tool by two reviewers independently. Data analysis was conducted using Stata 18.0 software, with the I 2 test for heterogeneity evaluation and funnel plots for qualitative assessment of publication bias. Results:A total of 13 RCTs were included, involving 1 653 participants. Meta-analysis showed that the intervention group had more favorable effects on SBP ( SMD:-0.91, 95%CI: -1.55–-0.27; Z=-2.79, P<0.005) and DBP ( SMD: -0.98, 95%CI: -1.62–-0.33; Z=-2.96, P<0.05) than the control diet. Fasting blood glucose ( SMD: 0.21, 95% CI: 0.01–0.41; Z=2.06, P=0.04) was statistically significant. There were no significant differences in body weight, BMI, fasting blood glucose, and triglyceride outcomes betweeen these two groups. Conclusions:DASH diet is effective in controlling SBP and DBP in patients with metabolic disorders and may be useful in clinical adjunctive therapy. However, current evidence does not support an independent improvement in glycolipid metabolic markers.

Objective: To investigate the characteristics of the time-point distribution of the occurrence of laryngopharyngeal reflux (LPR) by 24-hour multichannel intraluminal impedance-pH monitoring (24 h MII-pH) and to provide guidance for the development of individualized anti-reflux strategies for LPR patients. Methods: We conducted a retrospective analysis of 24 h MII-pH data from 408 patients [339 males and 69 females, aged 23-84 (55.08±11.08) years] attending the Department of Otorhinolaryngology Head and Neck Surgery at the Sixth Medical Center of the PLA General Hospital from January 2013 to March 2020. The number of gas acid/weak-acid reflux, mixed gas-liquid acid/weak-acid reflux, liquid acid/weak-acid reflux and alkaline reflux events at different time points were recorded and statistically analyzed through SPSS 26.0 software. Results: A total of 408 patients were included. Based on the 24 h MII-pH, the total positive rate of LPR was 77.45% (316/408). The type of positive gaseous weak-acid reflux was significantly higher than the remaining types of LPR (χ²=297.12,P<0.001). Except the gaseous weak-acid reflux, the occurrence of the remaining types of LPR showed a tendency to increase after meals, especially after dinner. Liquid acid reflux events occurred mainly between after dinner and the following morning, and 47.11% (57/121) of them occurred within 3 h after dinner. There was a significant positive association between Reflux Symptom Index scores and gaseous weak-acid reflux(r=0.127,P<0.01), liquid acid reflux(r=0.205,P<0.01) and liquid weak-acid reflux(r=0.103,P<0.05)events. Conclusions: With the exception of gaseous weak-acid reflux events, the occurrence of the remaining types of LPR events has a tendency to increase after meals, especially after dinner. Gaseous weak-acid reflux events accounts for the largest proportion of all types of LPR events, but the pathogenic mechanisms of gaseous weak-acid reflux are needed to further investigate.

Corrosive sclerosing cholangitis is a rare postoperative complication of hepatic cystic echinococcosis. Although corrosive sclerosing cholangitis is rare, it progresses rapidly and lacks effective treatments, which usually results in a poor prognosis. This case report retrospectively analyzed the treatment and diagnosis of a case with corrosive sclerosing cholangitis following surgical treatment of hepatic cystic echinococcosis, so as to provide insights into the diagnosis and treatment of corrosive sclerosing cholangitis.

Objective: To investigate the effect of gastroesophageal reflux disease (GERD) on the clinical characteristics of patients with laryngopharyngeal reflux disease(LPRD). Methods: The data of 141 patients with symptoms of LPRD, who were admitted to the Department of Pharyngology, Laryngology& Phonosurgery at the Sixth Medical Center of the PLA General Hospital from November 2020 to October 2021, were retrospectively analyzed.There were 118 males and 23 females, aged 28-75 (56.72±10.04) years old. The included patients underwent simultaneous 24-hour hypopharyngeal and esophageal multichannel intraluminal impedance pH monitoring (24h-HEMII-pH), salivary pepsin test at multiple times, Reflux Symptom Index (RSI), and Reflux Finding Score (RFS). One laryngopharyngeal reflux event on 24 h-HEMII-pH monitoring results was used as a diagnostic criterion for LPRD. And the duration of lower esophageal pH<4.0>4.0% at 24 h or DeMeester score>14.7 were used as diagnostic criteria for GERD. Among them, patients with both positive LPRD and GERD were classified as L&G group, patients with positive LPRD and negative GERD were classified as IL group, patients with negative LPRD and positive GERD were classified as IG group, and patients with both negative LPRD and GERD were classified as N group. The differences in the clinical characteristics of reflux and salivary pepsin assay in each group were statistically analyzed. SPSS 23.0 software was applied for statistical analysis. Results: According to the 24 h-HEMII-pH results, 116 (82.3%) patients were diagnosed with LPRD and 45 (31.9%) with GERD, including 82 (58.2%) in the IL group, 34 (24.1%) in the L&G group, 11 (7.8%) in the IG group, and 14 (9.9%) in the N group. Based on the salivary pepsin test, a total of 106 patients had positive results, and the L&G group had a significantly higher rate of positive total salivary pepsin test (94.1%) and positive morning test (70.6%) than the IL group (75.6%, 26.8%), IG group (63.6%, 27.3%) and N group (35.7%, 28.6%), with chi-square values of 19.01 and 20.81, both with P<0.001. The patients in the L&G group had a significantly higher RSI score (14.0) than the IL group (7.0), IG group (1.0) and N group (0), H=52.26,P<0.001. The difference in RFS between the L&G and IL groups was not statistically significant (Z=-0.92,P>0.05). Conclusion: Combined with GERD, LPRD patients have more obvious clinical symptoms and higher positive rate of pepsin test in saliva.

Objective To investigate the population dynamics and Echinococcus infections in small rodents around human settlement in Yushu City, Qinghai Province. Methods Rodents were captured using the mouse trap method in pastures from Batang Township and Longbao Township of Yushu City, Qinghai Province on May, August and October, 2018. The body weight and snout-vent length of all captured rodents were measured, and the species was identified according to the rodent morphology. Genomic DNA was extracted from rodent liver specimens and lesion specimens, and the mitochondrial cox1 gene of Echinococcus was amplified using PCR assay for identification of parasite species. In addition, the tissue specimens positive for PCR assay were sampled for pathological examinations. The prevalence of Echinococcus infections was estimated in rodents, and a phylogenetic tree was created based on Echinococcus cox1 gene sequences. Results A total of 285 small rodents were captured, including 143 Ochotona curzoniae (50.2%), 141 Lasiopodomys fuscus (49.5%), and 1 Neodon irene (0.3%), and there was a remarkable variation in habitat selection among these three rodent species. The number of L. fuscus correlated positively with vegetation coverage (r = 0.350, P = 0.264), with the greatest number seen in August, and the number of O. curzoniae negatively with vegetation coverage (r = −0.371, P = 0.235), with the highest number seen in August and the lowest number in May. The female/male ratios of O. curzoniae and voles were 1:0.96 and 0.82:1, respectively. The body weight (r = 0.519, P < 0.01) and snout-vent length (r = 0.578, P < 0.01) of O. curzoniae showed a tendency towards a rise with month, while the body weight (r = −0.401, P < 0.01) and snout-vent length (r = −0.570, P < 0.01) of voles presented a tendency towards a reduction with month. No Echinococcus infection was detected in voles, while 2.1% prevalence of E. shiquicus infection was seen in O. curzoniae. Phylogenetic analysis revealed consistent sequences of cox1 gene from E. shiquicus in Yushu City of Qinghai Province and Shiqu County, Ganzi Tibetan Autonomous Prefecture of Sichuan Province. Conclusions The small rodents around the human settlement in Yushu City of Qinghai Province mainly include O. curzoniae and L. fuscus, with the greatest numbers seen in May and August, respectively. Following the concerted efforts for echinococcosis control, the prevalence of Echinococcus infections is low in small rodents around the human settlement in Yushu City; however, there is still a risk of echinococcosis transmission.

Pneumonia caused by SARS-CoV-2 has seriously threatened human life and health worldwide and caused a large number of deaths. Viral infection and acute inflammation are important causes of death, so it is particularly important to combine antiviral therapy with anti-inflammatory therapy. Glycyrrhizic acid, the main component of the glycyrrhizic root extract, has a wide range of pharmacological effects as well as high efficiency and low toxicity, its preparation has been widely used in the treatment of chronic hepatitis and other diseases. Glycyrrhizic acid can regulate the expression and release of a variety of cytokines and play a significant anti-inflammatory effect. At the same time, glycyrrhizic acid also showed significant inhibition towards a variety types of viruses. Therefore, the potential application of glycyrrhizic acid as COVID-19 treatment should be explored.

Bluetongue virus (BTV) causes Bluetongue (BT) of ruminants vectored by culicoides midges. It is also a classic model for studying the release mechanism of non-enveloped virus. This review begins with the infection and assembly of BTV, then summarizes the advances of different ways of releasing BTV. This includes BTV-induced autophagy and the release as extracellular vesicles via multivesicular bodies, BTV-induced apoptosis and the lytic release, as well as different pathways of release through budding via plasma membrane. The regulatory mechanisms of NS3 which is a key non-structural protein during the release of BTV are also discussed, providing a basis for further understanding the molecular mechanisms underpinning the infection, proliferation and release of BTV.
