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.

Background Phenolic compounds, which are widely used as plasticizers, antibacterial agents, and preservatives in industrial production, have endocrine disrupting effects on humans. Previous epidemiological studies on the associations between phenolic compound exposure and blood lipids are mainly based on single measurement of spot urine samples, neglecting potential lag effects of phenolic compounds, and the conclusions are inconsistent. Objective To investigate the effects of short-term exposure to phenolic compounds at different lag days on blood lipid levels in adults. Methods We recruited 143 adults (43 males and 100 females) in Wuhan for three consecutive seasonal rounds of repeated visits: summer and autumn rounds of 2017 and winter of 2018. Morning urine samples were collected for four consecutive days during each round. A set of questionnaires were also distributed on the first day. Physical examinations and fasting venous blood sample collection were conducted on the fourth day. A total of 126 adults were included for analysis (340 person-time, 1251 urine samples). The concentrations of six urinary phenolic compounds [bisphenol A (BPA), bisphenol S (BPS), triclosan (TCS), methyl paraben (MeP), ethyl paraben (EtP), and propyl paraben (PrP)] were determined by ultra-high-performance liquid chromatography-tandem mass spectrometry. Linear mixed-effect models (LMEs), multiple informant models, and generalized linear models were utilized to estimate the associations of urinary phenolic compounds at different lag days with total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), and the ratio of TG to HDL-C (TG/HDL-C). Stratified analyses were conducted by selected characteristics. Results After covariate and multiple adjustments, the LMEs indicated that a change in urinary BPA at lag 0 day from the low concentration group (P _FDR<0.05), and this association was more pronounced in men (P _interaction=0.028) and smokers (P _interaction=0.040). In addition, a change in urinary TCS at lag 2 day from the low concentration group (P _FDR<0.05). The positive association of TCS with TG was more evident in subjects aged < 50 years (P _interaction=0.037). No significant associations were found between urinary phenolic compounds at other lag days and blood lipids. Conclusion Short-term exposures to BPA and TCS are positively correlated with unfavorable changes in blood lipids in adults, and the association seem to be more pronounced in men, smokers, or individuals aged < 50 years.

Objective To reveal the pharmacodynamic material basis of Kaixinsan by using high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)and the integrated analysis of"chemical component spectrum-plasma exposure component spectrum-mitochondrial function".Methods Through a review of literature,databases,and previous studies,the chemical components of ginseng,polygala,poria,and acorus were systematically cataloged.A qualitative analysis method for the chemical constituents in the aqueous extract of Kaixinsan was developed,allowing for the identification of its chemical components.A qualitative analysis for rat plasma based on HPLC-MS/MS was established,which was applied to analyze the plasma exposure component spectrum following oral administration of Kaixinsan aqueous extract in rats.Aerobic respiration was evaluated using a seahorse cell energy metabolism analyzer,and the effect of key components of Kaixinsan on mitochondrial aerobic respiration was assessed.Results Four main types of components were identified in the Kaixinsan aqueous extract,including saponins,oligosaccharide esters,xanthones,and triterpenes,comprising a total of 231 identified compounds.Analysis of rat plasma 30 minutes after gavage with Kaixinsan identified 55 compounds.The analysis revealed that ginsenoside Rg1,3,6'-disinapoylsucrose,polygalaxanthone Ⅲ and poricoic acid B could significantly enhance mitochondrial respiratory capacity using in vitro cellular assays to detect aerobic respiration of four main components entered blood.Conclusions Saponins,oligosaccharide esters,xanthones,and triterpenes may be the material basis for the pharmacological effect of Kaixinsan by improving mitochondrial function.The integrated analysis of"chemical component spectrum-plasma exposure component spectrum-mitochondrial function"provides a new approach for in-depth exploration of the material basis underlying the efficacy of traditional Chinese medicine.

Abstract: Objective To clarify the long-term evolution of hepatitis B virus (HBV) quasi-species in HBsAg asymptomatic carriers in Long'an county, Guangxi. Methods ELISA was used to detect serological markers of HBV. Viral loads were measured by real time PCR. HBV DNA was extracted from serum by kits. The whole HBV genome was amplified using nested PCR and amplicons were sequenced by next-generation sequencing (NGS). These sequences from NGS were analyzed by the software like Mega. Results Serum samples were collected from 9 HBsAg asymptomatic carriers in Longan County，Guangxi at 4 different time points in 2004, 2007, 2013, 2019 or 2020. A total of 23 serum samples and 309 full-length gene quasi-species sequences were obtained, with an average amount of (0.18±0.07) G sequencing data for each sample. Genotype of 55.54%(5/9) the studied subjects underwent genotype conversion during the long-term evolution process of HBV quasi-species, and the genotyping results of the phylogenetic tree in the PreS/S region are in perfect agreement with the results of the whole genome analysis; recombinant B/C, I/C were found; the Sn ranged from 0 to 0.37 and the genetic diversity ranged from 0 to 0.11, respectively. A total of 21 special single nucleotide/amino acid mutations (7 in the S region, 2 in the X region, 3 in the PreC region and 9 in the BCP region) and 6 deletion mutations were detected, multiple mutations were found and no drug resistant mutations were found; 77.8%(7/9) of the HBV strains carried by the subjects in 2004 had double mutations at nt1 762(A→T) and 1 764(G→A) and a stop mutation at nt1 896(G→A); HBV mutations can be restored from the mutant type to the wild type and (or) vice versa without antiviral drug pressure, and The evolution rate of HBV genome was 2.03×10-5~3.50×10-3.Conclusion HBV genotype, recombinants, genetic complexity and diversity of HBV quasi-species can change over time during in natural infection. The transformation between HBV mutation type and wild type reduces the value of predicting clinical outcomes by genetic types and related mutations to some extent. The HBV genome evolution rate of asymptomatic carriers of HBsAg in Long'an County is very high.

【Objective】 To investigate the feasibility of laparoscopic simple prostatectomy (LSP) in the treatment of large volume benign prostate hyperplasia (BPH). 【Methods】 Clinical and follow-up data of 30 patients with large volume BPH treated with LSP in our hospital during Feb.2019 and Dec.2021 were retrospectively analyzed. All patients underwent extraperitoneal LSP operation. The perioperative and 1-12 month postoperative follow-up data were analyzed. 【Results】 The average prostate volume was (92.4±38.9) mL, operation time (125±45) min, and weight of resected prostate (60.25±16.90) g. The hemoglobin decreased by (12.21±7.25) g/d after operation. No blood transfusion was needed. There was no need for bladder irrigation after operation in 21 cases (70%), and 9 cases (30%) had bladder irrigation time of (0.95±0.49) d. The postoperative catheter indwelling time was (6.92±2.51) d, and hospital stay (5.36±1.63) d. During the follow-up of (9.25±5.4) months, there was 1 case of postoperative intestinal obstruction (Clavien-Dindo grade II), 1 case of transient urinary incontinence (Clavien-Dindo grade I), and 1 case of delayed hematuria (Clavien-Dindo grade I). No urethral stricture occurred. The maximum urinary flow rate (Qmax), post-void residual urine volume (PVR), International Prostate Symptom Score (IPSS) and quality of life (QoL) 3 months after operation were significantly improved compared with those before operation (P<0.05). There was no significant difference in sexual function before and after operation (P>0.05). 【Conclusion】 LSP is safe and effective in the treatment of large volume BPH. It has advantages of complete resection of glands, minor bleeding and short postoperative bladder irrigation time. However, it still needs to be confirmed by a prospective control study of large samples.

Immunoglobulin (IgG) glycosylation affects the effector functions of IgG in a myriad of biological processes and has been closely associated with numerous autoimmune diseases, including systemic lupus erythematosus (SLE), thus underlining the pathogenic role of glycosylation aberration in autoimmunity. This study aims to explore the relationship between IgG sialylation patterns and lupus pregnancy. Relative to that in serum samples from the control cohort, IgG sialylation level was aberrantly downregulated in serum samples from the SLE cohort at four stages (from preconception to the third trimester of pregnancy) and was significantly associated with lupus activity and fetal loss during lupus pregnancy. The type I interferon signature of pregnant patients with SLE was negatively correlated with the level of IgG sialylation. The lack of sialylation dampened the ability of IgG to suppress the functions of plasmacytoid dendritic cells (pDCs). RNA-seq analysis further revealed that the expression of genes associated with the spleen tyrosine kinase (SYK) signaling pathway significantly differed between IgG- and deSia-IgG-treated pDCs. This finding was confirmed by the attenuation of the ability to phosphorylate SYK and BLNK in deSia-IgG. Finally, the coculture of pDCs isolated from pregnant patients with SLE with IgG/deSia-IgG demonstrated the sialylation-dependent anti-inflammatory function of IgG. Our findings suggested that IgG influences lupus activity through regulating pDCs function via the modulation of the SYK pathway in a sialic acid-dependent manner.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Objective:To summarize the complications and prevention after botulinum toxin type A(BTA) injection for masseter muscle hypertrophy(MMH).Methods:The clinical data of patients with masseter hypertrophy who received BTA injection in Shanxi Bethune Hospital from January 2019 to September 2021 were retrospectively analyzed. Injection method: 100 U BTA was prepared into a solution with a concentration of 50 U/ml with 2 ml 0.9% sodium chloride injection. The "safe injection zone" of the masseter muscle was marked. The anterior and posterior boundaries were the anterior and posterior edges of the masseter muscle, respectively. The upper boundary was the line from the corner of the mouth to the earlobe, and the lower boundary was the lower edge of the mandible. The injection points(3 or 4 points) were at least 1 cm away from the four borders, and 25-40 U was injected on each side. The patients were followed up after treatment, the types of complications were recorded, and the treatment measures were summarized.Results:A total of 160 patients were enrolled, including 8 males and 152 females, with a mean age of (30.6±6.2) years. All patients were followed up for 1 to 6 months. The masseter muscle of all patients was reduced to varying degrees, the lower facial lines were softer, and the facial contour was improved. The incidence of complications was 81.3%(130/160). There were four main types of complications: (1) Complications with a nonmuscular etiology include ecchymosis in 5 cases (3.1%) which resolved spontaneously in 5 to 7 days and headache occurred in 2 cases (1.3%) which disappeared in 2-3 days with proper rest. (2) The complication related to the toxin effect mainly was the decrease of masticatory power in 86 cases (53.8%), which gradually recovered with the drug metabolism for 3-12 weeks. (3) Dose-related complications include facial ptosis in 4 cases (2.5%) with 30-40 U dose per side. 2 cases without special treatment, gradually recovered in about 8-12 weeks. One patient underwent the BTA injection to raise the mandibular margin and gradually recovered about 2 weeks later. One patient recovered gradually with the treatment by Thermage in another hospital. There were 9 cases (5.6%) of paradoxical rigid masseter muscle bulge. 5 cases resolved within 1 week after supplementary injection of 4 U botulinum toxin, and the other 4 cases resolved spontaneously within 1 to 2 weeks without special treatment. (4) Complications related to the injection site include abnormal smiles in 3 cases (1.9%). Patients were instructed to practice the smile correctly and gradually recovered in 4-12 weeks. Twenty-one patients (13.1%) had sunken cheeks. One patient improved by injection of hyaluronic acid, and the other patients recovered gradually within 8-12 weeks without special treatment.Conclusion:The incidence of complications after BTA injection for MMH is high, and the manifestations are diverse. The injection should be performed in the recommended safe area of the masseter muscle. A reasonable dose and depth of injection can reduce the occurrence of complications.

Enzyme separation, purification, immobilization, and catalytic performance improvement have been the research hotspots and frontiers as well as the challenges in the field of biocatalysis. Thus, the development of novel methods for enzyme purification, immobilization, and improvement of their catalytic performance and storage are of great significance. Herein, ferritin was fused with the lichenase gene to achieve the purpose. The results showed that the fused gene was highly expressed in the cells of host strains, and that the resulted fusion proteins could self-aggregate into carrier-free active immobilized enzymes in vivo. Through low-speed centrifugation, the purity of the enzymes was up to > 90%, and the activity recovery was 61.1%. The activity of the enzymes after storage for 608 h was higher than the initial activity. After being used for 10 cycles, it still maintained 50.0% of the original activity. The insoluble active lichenase aggregates could spontaneously dissolve back into the buffer and formed the soluble polymeric lichenases with the diameter of about 12 nm. The specific activity of them was 12.09 times that of the free lichenase, while the catalytic efficiency was 7.11 times and the half-life at 50 ℃ was improved 11.09 folds. The results prove that the ferritin can be a versatile tag to trigger target enzyme self-aggregation and oligomerization in vivo, which can simplify the preparation of the target enzymes, improve their catalysis performance, and facilitate their storage.
