Objective: To analyze the association between poor sleep characteristics and the coexistence of negative emotions and overweight/obesity among college students, so as to provide a scientific basis for improving their physical and mental health. Methods: From November to December 2023, a convenience sampling method was used to survey 6 600 college students from nine universities in Jiangxi, Hunan, and Hubei provinces. The Depression Anxiety and Stress Scale-21 (DASS-21), Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and physical examinations were employed to assess negative emotions, poor sleep characteristics, and overweight/obesity. Chi square test and Logistic regression were used to analyze the impact of poor sleep characteristics on the coexistence of negative emotions and overweight/obesity. Results: The coexistence rates of different categories of negative emotions (depression, anxiety, stress) and overweight/obesity were 6.1% ( n= 405), 8.0% ( n =529), and 3.3% ( n =217), respectively. Gender, grade level, major, maternal education level, annual family income, physical activity level, only child status, and carbonated beverage consumption were statistically associated with the coexistence rates of different categories of negative emotions and overweight/obesity ( χ 2=4.01-35.18, all P <0.05). Logistic regression analysis showed that after adjusting for gender, grade level, major, only child status, maternal education level, annual family income, physical activity level, and carbonated beverage consumption, poor sleep characteristics were significantly associated with an increased risk of the coexistence of negative emotions and overweight/obesity ( OR =1.41-6.65); moderate and poor sleep quality levels were significantly associated with an increased risk of the coexistence of different categories of negative emotions and overweight/obesity among female students ( OR =1.99-4.71) (all P <0.05). Conclusions Poor sleep characteristics are associated with the coexistence of negative emotions and overweight/obesity among college students. Greater attention should be paid to sleep issues in this population, and sleep education should be actively promoted to reduce the risk of comorbid negative emotions and overweight/obesity.

OBJECTIVE To analyze the metabolites of Zhideke granules and speculate its metabolic pathway in rats in vivo. METHODS Male SD rats were randomly divided into blank group and administration group （Zhideke granules， 9.45 g/kg）； they were given ultrapure water or relevant medicine， twice a day， every 6-8 h， for 3 consecutive days. Serum， urine and feces samples of rats were collected， and their metabolites were identified by UPLC-Q-Exactive-MS technique after intragastric administration of Zhideke granules； their metabolic pathways were speculated. RESULTS After intragastric administration of Zhideke granules， 16 prototype components （i.g. irisflorentin， baicalin， chlorogenic acid） and 11 metabolites （i.g. hydration products of kaempferol or luteolin， methylation products of chlorogenic acid， and hydroxylation products of baicalin） were identified in serum， urine and feces of rats. Among them， 8 prototype components and 4 metabolites were identified in serum samples； 10 prototype components and 7 metabolites were identified in urine samples； 8 prototype components and 5 metabolites were identified in the fecal samples.

AIM:To investigate the mechanism of action of Wenweiyang decoction(WWYD)in treating func-tional dyspepsia in rats based on mast cell activation and stem cell factor(SCF)/receptor tyrosine kinase c-Kit signaling pathway.METHODS:Sixty SD rats were randomly divided into control group,model group,ranitidine hydrochloride capsule group,and low-,medium-and high-dose WWYD groups,with 10 rats in each group.The rat model of functional dyspepsia was established by tail clamping and irregular feeding compound senna method.After modeling,the rats in con-trol group and model group were given normal saline,while those in low-,medium-and high-dose(0.743 g/mL,1.485 g/mL and 2.970 g/mL)WWYD groups and ranitidine hydrochloride capsule(3 g/L)group were treated with corresponding drugs by intragastric administration.After treatment,the propulsion rate of the small intestine was measured by the carbon ink propulsion method.Rat duodenal mast cells were observed and counted by toluidine blue staining.ELISA was used for determination of mast cell tryptase(MCT)and histamine(HA)content in rat duodenum.The mRNA levels of SCF and c-Kit in duodenum were detected by RT-qPCR.Western blot and immunohistochemistry were employed to determine the ex-pression levels of SCF and c-Kit in the duodenum.RESULTS:Compared with model group,WWYD treatment signifi-cantly increased the propulsion rate of the small intestine in rats(P<0.05).ELISA results showed that WWYD reduced the number of mast cells and the content of MCT and HA in the duodenal mucosa tissue of rats(P<0.05).Western blot and immunohistochemistry results suggested that WWYD up-regulated the protein expression levels of c-Kit and SCF in the duodenal tissue of rats(P<0.05),and increased the numbers of SCF and c-Kit positive cells.RT-qPCR results indicated that WWYD up-regulated the mRNA expression of c-Kit and SCF in the duodenum of rats(P<0.05).Moreover,the small intestinal propulsion rate was negatively correlated with MCT and HA content,and positively correlated with the expres-sion of SCF and c-Kit.CONCLUSION:Wenweiyang decoction promotes rat duodenal motility,and its mechanism may be related to the inhibition of rat duodenal MCT and HA production and activation of SCF/c-Kit signaling pathway.

Objective To investigate the clinical effect and safety of endoscopic inlay butterfly cartilage tympanoplasty(BCT)by day surgery mode.Method 120 patients with tympanic membrane perforation from June 2021 to June 2022 were randomly divided into two groups,the observation group of 60 patients underwent endoscopic inlay BCT,the control group of 60 patients underwent endoscopic tympanic membrane repair with tragus cartilage membrane.Both groups of patients completed all preoperative examinations in the outpatient department and completed the steps of admission,surgery,and discharge within 24 h.The surgical conditions(operation time and intraoperative blood loss),pure tone average(PTA)after 6 months,air-bone gap(A-B gap)after 6 months,tympanic membrane healing rate,and complications were compared between the two groups.Results There was no statistical significance in the operation time and intraoperative blood loss between the observation group and the control group(P>0.05).After 6 months,the PTA and A-B gap of both groups were lower than those before the surgery(P<0.01),the observation group had a significantly lower PTA(23.40±4.40)dB HL and A-B gap(9.11±3.13)dB HL than the control group(29.12±3.33)dB HL and(14.86±3.20)dB HL,with statistically significant differences(P<0.05).There was no statistical significance in the tympanic membrane healing rate between the two groups after surgery(P>0.05),but the incidence of complications in the observation group was 5.0%(3/60),significantly lower than that in the control group(21.7%,13/60),with a statistically significant difference(P<0.05).Conclusion Endoscopic inlay BCT is safe and effective in the treatment of tympanic membrane perforation,with better hearing recovery than tragus cartilage membrane repair surgery,fewer complications,and more suitable for day surgery mode.It is worthy clinical application.

BACKGROUND: Osteoporosis (OP) has become a major public health issue, threatening the bone health of middle-aged and elderly people from all around the world. Changes in the gut microbiota (GM) are correlated with the maintenance of bone mass and bone quality. However, research results in this field remain highly controversial, and no systematic review or meta-analysis of the relationship between GM and OP has been conducted. This paper addresses this shortcoming, focusing on the difference in the GM abundance between OP patients and healthy controls based on previous 16S ribosomal RNA (rRNA) gene sequencing results, in order to provide new clinical reference information for future customized prevention and treatment options of OP. METHODS: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), we comprehensively searched the databases of PubMed, Web of Science, Embase, Cochrane Library, and China National Knowledge Infrastructure (CNKI). In addition, we applied the R programming language version 4.0.3 and Stata 15.1 software for data analysis. We also implemented the Newcastle-Ottawa Scale (NOS), funnel plot analysis, sensitivity analysis, Egger's test, and Begg's test to assess the risk of bias. RESULTS: This research ultimately considered 12 studies, which included the fecal GM data of 2033 people (604 with OP and 1429 healthy controls). In the included research papers, it was observed that the relative abundance of Lactobacillus and Ruminococcus increased in the OP group, while the relative abundance for Bacteroides of Bacteroidetes increased (except for Ireland). Meanwhile, Firmicutes, Blautia, Alistipes, Megamonas, and Anaerostipes showed reduced relative abundance in Chinese studies. In the linear discriminant analysis Effect Size (LEfSe) analysis, certain bacteria showed statistically significant results consistently across different studies. CONCLUSIONS: This observational meta-analysis revealed that changes in the GM were correlated with OP, and variations in some advantageous GM might involve regional differences.

Objective:To explore the changes of intracranial pressure in intensive care unit (ICU) patients during the occurrence and evolution of delirium by using bedside ultrasound to measure the optic nerve sheath diameter (ONSD) to evaluate intracranial pressure.Methods:A retrospective observational study was conducted. Adult patients who developed delirium during hospitalization in the general ICU of Beihai People's Hospital from October 2020 to November 2021 were enrolled, and patients who did not have ultrasonographic ONSD records within 24 hours after the diagnosis of delirium were excluded. The ONSD measured before delirium was recorded as ONSD 0, the ONSD measured within 24 hours of the onset of delirium recorded as ONSD 1, and the ONSD reexamined after ONSD 1 recorded as ONSD 2. Patients were divided into intracranial hypertension group (ONSD 1 > 5 mm) and normal intracranial pressure group (ONSD 1 ≤ 5 mm) according to the size of ONSD 1. According to the outcome of delirium, the patients were divided into cured, improved, and non-improved groups. The reduction ratio of ONSD 2 to ONSD 1 in the three groups were calculated and compared. Pearson correlation test was used to analyze the correlation between fluid balance and ONSD changes after delirium. Results:There were 43 patients, including 40 cases in the intracranial hypertension group (the incidence rate was 93.0%), 3 cases in the normal intracranial pressure group, 23 cases were cured, 13 cases were improved, and 7 cases were not improved. In the intracranial hypertension group, 11 cases had ONSD 0 and ONSD 1 records, and ONSD 1 was significantly higher than ONSD 0 [mm: 5.88±0.61 vs. 5.34±0.57, 95% confidence interval (95% CI) -0.85 to -0.23, P = 0.003]. The reduction ratio of ONSD 2 to ONSD 1 in the cured group was significantly higher than that in the improved group and the non-improved group [(12.04±6.20)% vs. (5.68±4.10)%, (0.17±3.96)%; 95% CI were 2.37 to 10.33, 6.41 to 17.31, P values were 0.003 and 0.000, respectively]. The correlation analysis showed that the reduction ratio of ONSD 2 to ONSD 1 was negatively correlated with fluid balance ( r = -0.42, 95% CI was -0.66 to -0.10, P = 0.012). Conclusions:The incidence of intracranial hypertension in ICU delirium patients is high. A more pronounced decrease in intracranial pressure predicts a better delirium outcome. Dynamic ONSD measurement can provide valuable information for the prevention and treatment of delirium.

Objective: To understand the longitudinal changes of refractive errors in adolescent myopia screening in the suburb of Shanghai, and to provide reference for targeted measures of myopia prevention and intervention. Methods: By using the cluster sampling method, 1 346 students were selected from two primary schools in a town in the suburb of Shanghai. Physical development indicators and refractive examination parameters of non ciliary muscle paralysis, and uncorrected visual acuity in 2017 and 2020 were collected from the Shanghai adolescent refractive development file. Longitudinal change of spherical equivalent (SE) refractive were assessed. A linear regression model was used to examine the relationship between the rate of SE change with characteristics of the students. Results: The average annual incidence of myopia was 16.36%, and the SE degrees of the left and right eyes of myopia students decreased by 225 degrees for three years. Girls (right eye Z=-4.33; left eye Z=-3.75, P<0.01), newly-onset myopia and persistent myopia (right eye Z=634.45; left eye Z=638.85, P<0.01) was a key for the rapid progress of refractive power. Conclusion The proportion of students with severe low vision is relatively high, and the apparent shifts toward more hyperopia in myopia students call for effective prevention and control programs based on changes in refractive to slow the progression of adolescent myopia.

The grey correlation analysis showed that the correlation between all common peaks and analgesic and anti- inflammatory effects were greater than 0.6 （except the correlation between peak 6 and analgesic effects ），showing correlation relationship ；the correlation of peaks 3，7 and 10 with analgesic and anti-inflammatory effects were all greater than 0.8，which was highly related. Bivariate correlation analysis showed that the correlation of peak 1，3，4，7，9，10，11 with analgesic and anti-inflammatory effects were all greater than 0.6，showing correlation relationship. PLS method showed that peaks 1，3，4，7，9，10，11 contributed greatly to playing an analgesic and anti-inflammatory role. CONCLUSIONS ：HPLC fingerprints of different polar parts of C. muricatum is established and five common peak components were identified. Neochlorogenic acid ，isochlorogenic acid A ，isochlorogenic acid C and chemical components represented by peaks 1，4，7，9 may be the pharmacodynamic substances of C. muricatum to exert analgesic and anti-inflammatory effects.

OBJECTIVE: To assess the value of combined chromosomal karyotyping and chromosomal microarray analysis (CMA) for prenatal diagnosis. METHODS: G-banding karyotyping and CMA were simultaneously performed on 546 women who were subjected to amniocentesis during middle pregnancy. RESULTS: In total 82 cases were detected with chromosomal abnormalities. The two methods were consistent in 43 cases, which included 14 trisomy 21, 6 trisomy 18, 1 trisomy 13, 14 sex chromosomal aneuploidies, 4 chromosomal deletions, 3 chromosomal duplications and 1 sex chromosomal mosaicism. Fifteen fetuses with chromosomal abnormalities detected by CMA were missed by karyotyping analysis, which included 9 microdeletions and 6 microduplications. Sixteen fetuses with chromosomal abnormalities detected by karyotyping analysis were missed by CMA, which included 15 chromosomal translocations and 1 sex chromosomal mosaicism. In 7 cases, the results of karyotyping analysis and CMA were inconsistent. One supernumerary marker chromosome detected by karyotyping analysis was verified by CMA as 9p13.1p21.1 duplication. CONCLUSION Combined chromosomal karyotyping and CMA can significantly improve the detection rate for chromosomal abnormalities, which has a great value for prenatal diagnosis.
