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 explore the comorbidity and associated factors of dental caries and overweight/obesity among primary and secondary school students in Guangxi, so as to provide a scientific basis for the development of targeted prevention strategies. Methods: A stratified cluster random sampling method was used to survey 178 700 students from the fourth grade of primary school to the third year of high school in Guangxi Zhuang Autonomous Region from September to November 2023, including physical examination, oral screening, and questionnaire survey. Chisquare tests and binary Logistic regression analysis were employed to investigate the related factors of the cooccurrence of dental caries and overweight/obesity among students. Results: The comorbidity rate of dental caries and overweight/obesity was 9.55%, with urban areas (9.95%) higher than rural counties (9.24%), boys (10.54%) higher than girls (8.54%), primary school students (11.49%) higher than senior high school students (8.92%) and junior high school students (8.05%), and nonboarding students (11.44%) higher than boarding students (7.94%), and all differences were statistically significant (χ2=26.07, 207.91, 471.54, 629.14,P<0.01). Multivariate Logistic regression analysis showed that consuming cereal for breakfast (OR=0.91, 95%CI=0.88-0.94), drinking milk in the past week (OR=0.89, 95%CI=0.83-0.95), meeting sleep standards (OR=0.95, 95%CI=0.91-0.99), and brushing teeth at least once a day (OR=0.82, 95%CI=0.73-0.93) had a lower risk of the comorbidity of dental caries and overweight/obesity. In contrast, drinking beverages in the past week (OR=1.14, 95%CI=1.09-1.20), consuming fried foods in the past week (OR=1.11, 95%CI=1.06-1.17), eating fruit ≥1 time every day (OR=1.06, 95%CI=1.02-1.11), consuming fruit ≥1 type every day (OR=1.07, 95%CI=1.01-1.12), and having fish, poultry, meat, or eggbased breakfasts (OR=1.03, 95%CI=1.05-1.13) had a higher risk of the comorbidity of dental caries and overweight/obesity (P<0.05). Conclusions Dietary habits and lifestyle behaviors are associated with the comorbidity of dental caries and overweight/obesity among primary and secondary school students in Guangxi. Guiding students to form healthy living habits is helpful to preven dental caries and overweight/obesity.

Objective: To investigate the prevalence and associated factors of spinal curvature abnormalities among primary and secondary school students in the Guangxi Zhuang Autonomous Region, so as to provide a scientific basis for the prevention and control of such abnormalities. Methods: From September to November 2023, adopting a stratified cluster random sampling method, spinal curvature screenings and questionnaire surveys were conducted among 168 931 students from grade 4 of primary school to grade 12 of high school in 111 districts and counties across 14 cities in Guangxi. Chi square tests and binary Logistic regression analysis were used to analyze influencing factors of spinal curvature abnormalities. Results: In 2023, the detection rate of poor posture among students above grade 4 in Guangxi was 4.24% , and the detection rate of spinal curvature abnormalities was 2.13%. The detection rate was higher among urban students (2.84%) than rural students (1.66%), boarding students (2.61%) than non-boarding students (1.60%), and high school students (3.16%) than junior high (2.45%) and primary school students (1.15%), and the differences were statistically significant ( χ 2=269.85, 221.44, 565.10, P <0.01). A trend of increasing detection rates with higher grade levels was observed ( χ 2 trend =617.63, P <0.01). Binary Logistic regression analysis indicated that students without boarding at school ( OR =0.82, 95% CI =0.75-0.90), engaging in high-intensity physical activity for over 60 min per day ≥5 days per week ( OR =0.90, 95% CI =0.82-0.98), and adequate sleep ( OR =0.87, 95% CI =0.81-0.94) had lower risks of detecting spinal curvature abnormalities ( P <0.05). Conclusions The prevalence of spinal curvature abnormalities increases with grade level among primary and secondary school students in Guangxi. Regular moderate-to-vigorous physical activity demonstrates protective effects against spinal abnormalities.

Objective:To observe the recurrence condition of hepatitis B in different risk groups after liver transplantation in an attempt to provide useful information on whether to discontinue hepatitis B immunoglobulin (HBIG) in the future at an early stage.Methods:The patient population was divided into high, low-risk, and special groups [especially primary hepatocellular carcinoma (HCC)] according to the guidelines for the prevention and treatment of hepatitis B recurrence after liver transplantation. The recurrence condition and risk factors in this population were observed for hepatitis B. Measurement data were analyzed using a t-test and a rank-sum test. Count data were compared using a χ2 test between groups. Results:This study finally included 532 hepatitis B-related liver transplant cases. A total of 35 cases had HBV recurrence after liver transplantation, including 34 cases that were HBsAg positive, one case that was HBsAg negative, and 10 cases that were hepatitis B virus (HBV) DNA positive. The overall HBV recurrence rate was 6.6%. The recurrence rate of HBV was 9.2% and 4.8% in the high- and low-risk HBV DNA positive and negative groups before surgery ( P = 0.057). Among the 293 cases diagnosed with HCC before liver transplantation, 30 had hepatitis B recurrence after surgery, with a recurrence rate of 10.2%. The independent related factors for the recurrence of hepatitis B in patients with HCC after liver transplantation were HCC recurrence ( HR =181.92, 95% CI 15.99~2 069.96, P < 0.001), a high postoperative dose of mycophenolate mofetil dispersible tablets (MMF) ( HR =5.190, 95% CI 1.289~20.889, P = 0.020), and a high dosage of HBIG ( HR = 1.012, 95% CI 1.001~1.023, P = 0.035). Among the 239 cases who were non-HCC before liver transplantation, five cases (recurrence rate of 2.1%) arouse postoperative hepatitis B recurrence. Lamivudine was used in all cases, combined with on-demand HBIG prophylaxis after surgery. There was no hepatitis B recurrence in non-HCC patients who treated with entecavir combined with HBIG after surgery. Conclusion:High-barrier-to-resistance nucleotide analogues combined with long-term HBIG have a good effect on preventing the recurrence of hepatitis B after liver transplantation. The discontinuation of HBIG may be considered at an early stage after administration of a high-barrier-to-resistance nucleotide analogue in low-risk patients. Domestically, the HBV infection rate is high, so further research is still required to explore the timing of HBIG discontinuation for high-risk patients, especially those with HCC.

Objective:To explore the application effect of mindfulness meditation training in patients with heart failure treated by left bundle branch area pacing cardiac resynchronization therapy.Methods:Using the convenient sampling method, a total of 86 patients with heart failure who were admitted to the Heart Center of Henan Provincial People's Hospital from March 2019 and March 2020 were selected as the research objects. According to the random number table method, a total of 86 patients were divided into the observation group and the control group, with 43 cases in each group. Patients in the control group were given routine nursing and health education, while patients in the observation group were given mindfulness meditation intervention on this basis. Self-rating Anxiety Scale (SAS) , Self-rating Depression Scale (SDS) and Pittsburgh Sleep Quality Index (PSQI) were used to compare the intervention effects.Results:After intervention, scores of SAS, SDS and PSQI of patients in the two groups were all lower than those before intervention, and scores of SAS, SDS and PSQI of patients in the observation group were all lower than those in the control group, and the differences were statistically significant ( P< 0.05) . Conclusions:Mindfulness meditation intervention in patients with chronic heart failure treated by left bundle branch area pacing cardiac resynchronization therapy can effectively reduce their negative emotions and improve their sleep quality.

Objective To explore the influence of disability acceptance and resilience on stigma in laryngeal carcinoma patients with permanent tracheostomy and analyze the impact path. Methods From June 2016 to August 2018, this study selected 264 laryngeal carcinoma patients with permanent tracheostomy of Inpatient and Outpatient Department in Guangxi Medical University Affiliated Tumor Hospital as subjects by convenience sampling. All patients were investigated with the Social Impact Scale (SIS), Acceptance of Disability Scale (AODS) and the 10-item Connor-Davidson Resilience Scale (CD-RISC10). The correlations were analyzed and structure equation model was used to path analysis. A total of 264 questionnaire were sent out and 256 valid questionnaires were collected. Results Among those patients with permanent tracheostomy, the total scores of stigma, disability acceptance and resilience were (61.50±9.27), (76.88±9.34) and (26.49±4.05) respectively. Correlation analysis showed that the scores of disability acceptance and resilience had negative correlations with stigma with statistical differences (P< 0.01). Structure equation model analysis showed that disability acceptance and resilience of laryngeal carcinoma patients with permanenttracheostomy had direct effect on stigma (β=-0.43,-0.28), the indirect effect of disability acceptance on stigma by resilience was -0.06. Conclusions Laryngeal carcinoma patients with permanenttracheostomy have a high level of stigma, the disability acceptance and resilience has significant roles on stigma.

Objective To explore the expression and clinical pathological significance of long non-coding transcription factor 7 (lncTCF7) in gastric cancer tissues and to investigate the role of lncTCF7 in the invasion and metastasis of gastric cancer by in vitro experimental study.Methods From January to June 2011,one hundred patients with gastric cancer who underwent radical gastrectomy were selected from Renji Hospital Affiliated to Shanghai Jiao Tong University School of Medicine.The expression of lncTCF7 at mRNA level was detected by quantitative real-time polymerase chain reaction (qRT-PCR).The patients were divided into high expression group (50 cases) and low expression group (50 cases) according to the lncTCF7 mRNA expression level.The stable interferenced lncTCF7 cell line (stable interference group) and blank control lncTCF7 cell line (blank control group) were established.Then the relationship between lncTCF7 expression level and clinical pathological characteristics and prognosis was analyzed.The interferenced lncTCF7 cell line was constructed and utilized,and the role of lncTCF7 in the invasion and metastasis of gastric cancer was detected by wound healing,Transwell and Western blotting method.The Chi square test and t test were performed for statistical analysis.The Kaplan-Meier curve was used for survival analysis.Univariate and multivariate analyses were used for screening the independent factors affecting prognosis.Results The results of qRT-PCR showed that the expression levels of lncTCF7 mRNA in high expression group and low expression group were 0.019 ± 0.003 and 0.002 ± 0.001,respectively.The survival rate of high expression group was lower than that of low expression group (46％,23/50 vs.72％,36/50),and the difference was statistically significant (P =0.002 5).The expression level of lncTCF7 was correlated with intravascular tumor thrombus formation,nerve invasion,depth of invasion and lymph node metastasis (x2 =7.862,7.162,11.903 and 8.280,all P ＜ 0.05).The results of univariate and multivariate analyses showed that the expression level of lncTCF7 was significantly correlated with the depth of invasion (hazard ratio (HR) =4.205,P =0.002;HR =3.125,P =0.018).The results of wound healing assay indicated that lncTCF7 interference could significantly inhibit wound healing ((92.90 ± 1.51) ％ vs.(12.33 ± 0.67) ％,t =48.72,P ＜ 0.01).The results of Transwell assay demonstrated that after 24 hours of culture the number of cells passed through the membrane of the chamber of blank control group was higher than that of stable interference group (83.6 ± 12.5 vs.26.6 ± 4.3),and the difference was statistically significant (t =9.65,P ＜ 0.01).The results of Western blotting showed that the expression of E-cadherin,a marker of epithelial origin,of stable interference group was significantly increased compared with that of blank control group (0.32 ±0.01 vs.0.76 ± 0.01),however the expression levels of vimentin and N-cadherin,markers of mesenchymal origin,were significantly decreased (0.56 ±0.01 vs.0.39 ± 0.01 and 0.67 ± 0.01 vs.0.33 + 0.01),and the differences were all statistically significant (t =26.68,10.09 and 24.14,all P ＜ 0.05).Conclusions The prognosis of gastric cancer patients with high expression of lncTCF7 is poor.lncTCF7 may promote the invasion and metastasis of gastric cancer by influencing eoithelial-mesenchymal transition in gastric cancer cells.

Objective To study the correlation between characteristic parameters of photoplethysmography( PPG)and severity of coronary artery lesions.Methods Two hundred and twenty-six CHD patients who underwent CAG in our hospital from August 2018to November 2018were divided into single-vessel lesion group(n=55),double-vessel lesion group(n=74)and multi-vessel lesion group(n=97)according to their CAG.Their stiffness index(SI),crest time(CT),normalized crest time(NCT)and crest time ratio(CTR)were recorded by PPG and analyzed by correlation analysis.Results The SI was significantly different in single-vessel lesion group,double-vessel lesion group and multi-vessel lesion group(6.479±0.819m/s,6.692±1.051m/s and 6.943±1.096m/s,P=0.024).No significant difference was detected in CT,NCT and CTR among single-vessel lesion group,double-vessel lesion group and multi-vessel lesion group(P＞0.05).The SI was positively correlated with the severity of coronary artery lesions(r=0.162,P=0.015).Conclusion The SI is correlated with the severity of coronary artery lesions,which is of a certain value in predicting the severity of coronary artery lesions.

Western blotting of autophagic markers LC3Ⅱ and p62 are widely used for estimating autophagic activity. To compare the regulation of various autophagy modulators on LC3Ⅱ and p62,HEK293 cells were treated separately with mTOR-dependent autophagy activator rapamycin or -independent autophagy activators trehalose, and autophagy inhibitors including 3-methyladenine (3-MA),bafilomycin A1 or E64d and pepstatin A that inhi-bited the initiation of autophagy,the fusion of autophagosome and lysosome,and the activities of lysosomal enzymes accordingly,and then LC3Ⅱ and p62 levels were assessed. Western blot results demonstrated that rapam-ycin enhanced the conversion of LC3I to LC3Ⅱ,promoted the degradation of p62 simultaneously,while trehalose merely increased the expression of LC3Ⅱ with no influence on the p62 level. Moreover,inhibition of autophagy commonly led to accumulation of LC3Ⅱ as well as blockage of p62 degradation in a concentration- and time-dependent manner. These results indicate that obvious differences exist in the regulation of LC3Ⅱ and p62 by various modulators although both are autophagic markers.
