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. CONCLUSIONS The metabolites of Zhideke granules in rats mainly include baicalin， irisflorentin，chlorogenic acid， and the main metabolic pathways included methylation， hydroxylation， glucuronidation.

Objective:To investigate the clinical outcomes of using autologous mandibular outer cortex "sandwich" grafting to augment mandible for correcting lower facial asymmetry with normal occlusal relationships.Methods:A retrospective analysis was conducted on the clinical data of patients with lower facial asymmetry treated at the Department of Plastic Surgery, the Affiliated Friendship Plastic Surgery Hospital of Nanjing Medical University, from January 2016 to December 2019. Preoperative cone-beam CT (CBCT) scans of the maxillofacial region were obtained to acquire three-dimensional data of the maxillofacial skeleton. Computer-aided design was used to determine the osteotomy range of the mandibular outer cortex and design osteotomy guide template. The outer cortex of the larger mandibular side (donor site) was harvested according to the osteotomy guide template and sectioned. The segmented mandibular outer cortex was then contoured to match the arc of the recipient side’s mandibular outer cortex and fixed to the inner side of the recipient mandibular outer cortex, thus increasing the width and thickness of the expanded mandible. Follow-up was conducted at 7th day and 6 months postoperatively, CBCT scan was performed to measure the changes in ramus height (Co-Go), mandibular body length (Go-Me), and mandibular outer cortex thickness, and volume, and the patient satisfaction with facial appearance (1 to 5 points, with higher scores indicating higher satisfaction), were assessed to evaluate surgical outcomes. Statistical analysis was performed using SPSS 12.0 software. Paired t-tests were used to compare patient satisfaction scores preoperatively and six months postoperatively. Repeated measurement ANOVA was used to compare Co-Go and Go-Me measurements preoperatively, 7th day, and 6 months postoperatively. If a statistically significant difference is found, further analysis using post-hoc testing(Tukey’s HSD test) will be conducted to examine the data. Results:Sixteen patients with lower facial asymmetry were included, comprising of 5 males and 11 females, aged 18 to 40 years, with an average age of 25.2 years. Surgical method included contralateral mandibular outer cortex "sandwich" grafting to the expanded mandible in 9 cases and simultaneous genioplasty in 7 cases. Follow-up ranged from 6 months to 5 years, with an average follow-up of 18.6 months. All patients experienced numbness of the lower lip postoperatively, which resolved within six months, and no severe complications occurred. The symmetry of lower facial contour improved significantly and remained stable. Patient satisfaction score for facial appearance increased from (1.63±0.62) points preoperatively to (4.19±0.75) points six months postoperatively( P<0.01). The differences in Co-Go on the donor side and Go-Me on the recipient side across the three time points(preoperatively, 7th day and 6 months postoperatively) were not statistically significant(all P>0.05). However, the differences in Go-Me on the donor side and Co-Go on the recipient side across the three time points were statistically significant(all P<0.05). On the donor side, the mandibular outer cortex thickness decreased by a maximum of 6 mm on 7th day postoperatively and increased by a maximum of 2 mm at 6 months postoperatively compared to 7th day. On the recipient side, mandibular outer cortex thickness increased by a maximum of 6 mm on 7th day postoperatively and decreased by a maximum of 2 mm at six months postoperatively compared to 7th day. The volume of the mandibular outer cortex on the recipient side increased by (4 415.94±1 017.21)mm 3 at 7th day postoperatively compared to preoperatively, and decreased by (202.63±300.85)mm 3 at 6 months postoperatively. Conclusion:For lower facial asymmetrical with normal occlusal relationships and no occlusal plane deviation, contralateral mandibular outer cortex "sandwich" bone grafting can effectively increase the width and volume of the mandible on the grafted side, achieving favorable clinical outcomes.

Objective To investigate whether resveratrol alleviates hyperglycemia-induced cardiomyocyte hypertrophy by enhancing the expression of silent information regulation 2 homolog 1(SIRT1)to maintain mitochondrial homeostasis.Methods Rat cardiomyocytes H9c2 cells with or without lentivirus-mediated mRNA interference of SIRT1 were cultured in high glucose(HG)and treated with resveratrol for 72 h.The changes in superoxide dismutase(SOD)activity,malondialdehyde(MDA)content,reactive oxygen species(ROS)level,and relative surface of the cells were examined,and the mRNA expressions of atrial natriuretic factor(ANF)and brain natriuretic peptide(BNP)and protein expressions of SIRT1,mitochondrial fusion related proteins optic atrophy protein 1(OPA1)and mitofusin 2,mitochondrial division related proteins dynamin-related protein 1(DRP1)and fission protein 1(FIS1),and mitophagy-related proteins BNIP3L and LC3 were detected using RT-qPCR and Western blotting.Results HG exposure significantly decreased SOD activity,increased MDA content,ROS production,relative cell surface,and the mRNA expressions of ANF and BNP in the cardiomyocytes;the protein expressions of SIRT1,OPA1,mitofusin 2 and BNIP3L and LC3-Ⅱ/LC3-Ⅰ ratio were all decreased and the protein expressions of DRP1 and FIS1 increased in HG-exposed cells(P<0.01).All these changes in HG-exposed cardiomyocytes were significantly alleviated by treatment with resveratrol(P<0.05).The protective effects of resveratrol against HG exposure in the cardiomyocytes were obviously attenuated by transfection of the cells with si-SIRT1(P<0.05).Conclusion Resveratrol inhibits hyperglycemia-induced cardiomyocyte hypertrophy by reducing oxidative stress,the mechanisms of which involve enhancement of SIRT1 protein expression,regulation of mitochondrial fusion and division balance,and promoting BNIP3L-mediated mitophagy to maintain mitochondrial homeostasis in the cells.

OBJECTIVE To explore the effect of changing lifestyle diet in the treatment of laryngeal reflux disease(LRPD).METHODS A total of 92 patients with LRPD who received outpatient treatment in the Second Affiliated Hospital of Fujian Medical University from January 2022 to June 2023 were selected as the study control,divided into control group(46 cases)and treatment group(46 cases).The control group was treated with conventional acid suppression and gastric motogenic therapy.The treatment group was treated on the basis of the control group with giving guidance on lifestyle and diet.The changes of reflux symptom index scale(RSI)and reflux sign score scale(RFS)and the clinical efficacy of the two groups were compared 8 weeks and 12 weeks after treatment.RESULTS RSI total score was improved 8 weeks after treatment compared with before treatment in both RSI control group and treatment group(P＜0.05).The total RSI score of 12 weeks after treatment was improved compared with that of 8 weeks after treatment in both control and treatment groups(P＜0.05).The total RFS score at 8 weeks after treatment was improved in both control group and treatment group compared with before treatment(P＜0.05).Compared with 8 weeks after treatment,the total RFS score in both control group and treatment group was improved(P＜0.05).After 8 weeks of treatment,the total effective rate of the control group(60.9%)was compared with that of the treatment group(71.7%),and there was no significant difference between the two groups(χ2=1.335,P=0.513).After 12 weeks of treatment,the total effective rate of the control group(73.9%)was compared with the total effective rate of the treatment group(91.3%),and the difference between the two groups was statistically significant(χ2=6.226,P=0.044).CONCLUSION The change of lifestyle and diet should become an important part of the treatment of LRPD.By adjusting the unhealthy lifestyle and diet,the symptoms of patients can be significantly reduced and better clinical efficacy can be obtained.

{L-End}Objective To understand the influence of job burnout and anxiety symptoms on work ability of biosafety laboratory (BSL) workers in Xinjiang Uygur Autonomous Region. {L-End}Methods A total of 5 808 BSL workers in Xinjiang Region were selected as the research subjects using cluster sampling method. The Job Burnout Questionnaire, Anxiety Self-rating Scale and Work Ability Index Questionnaire were used to evaluate their job burnout, anxiety symptoms and work ability. The mediation effect of anxiety symptoms on the relationship between job burnout and work ability was tested by stepwise regression analysis. {L-End}Results The detection rate of job burnout, anxiety symptoms and poor working ability was 83.1% (4 829/5 808), 37.2% (2 160/5 808) and 5.8% (339/5 808), respectively. There was a positive correlation between job burnout and anxiety symptoms score in BSL workers ［correlation coefficient (r) was 0.48, P<0.01］. The score of job burnout and anxiety symptoms was negatively correlated with the work ability score (r were -0.58, -0.51, both P<0.01). The results of mediation effect analysis show that the total effect of job burnout on work ability was -0.31, with the direct effect of -0.15. The mediation effect of anxiety symptoms on the relationship between job burnout and work ability was -0.16, accounting for 51.6% of the total effect. {L-End}Conclusion The detection rates of job burnout and anxiety symptoms among BSL workers in Xinjiang Region are relatively high. Anxiety symptoms show a mediate effect on the relationship between job burnout and work ability. The work ability of BSL workers can be improved by improving job burnout and anxiety symptoms.

Objective:To analyze the incidence and prognosis of epilepsy in frontotemporal lobe glioma.Methods:The clinical data of 208 patients with frontotemporal lobe gliomas in Sanbo Brain Hospital Capital Medical University from 2019 to 2021 were analyzed retrospectively. According to the 2016 World Health Organization (WHO) classification of tumors of the central nervous system, the incidence of epilepsy, Modified Rankin Scale (MRS) score, and Engel Outcome Scale of patients with different grades of tumors were calculated.Results:Among all the patients with frontotemporal lobe gliomas, there was more males than females, and it was more common in the 40 -59 age group. The incidence of epilepsy associated with WHO grade Ⅰand Ⅱ glioma was 100.0% (33/33) and 60.9% (14/23), respectively, while that of WHO grade Ⅳ glioma was 19.0%(19/100). The average follow-up time was (22 ± 9) months. During the follow-up period, the incidence of WHO grade Ⅰ, Ⅱ and Ⅲ glioma-related epilepsy decreased significantly. There was no significant difference in the incidence of glioma-related epilepsy between the total and subtotal resection groups ( P>0.05). There was no statistical correlation between the side of tumor occurrence and the occurrence of epilepsy ( P>0.05), also between the gene phenotype and the occurrence of epilepsy ( P>0.05). There was no significant difference in the Engel Outcome Scale among different grades of gliomas ( P>0.05). The prognosis of patients with Engel Outcome Scale Class 1 was significantly better than that of other grades. Conclusions:The incidence of glioma-related epilepsy is negatively correlated with tumor grade. Age and sex are risk factors for glioma-related epilepsy. The incidence of postoperative epilepsy in patients with low grade glioma is significantly lower than that in patients with high grade glioma, and the prognosis is better. However, there is no significant difference in the Engel Outcome Scale among different grades of gliomas.

Objective:To investigate the risk factors of gout and establish a columnar graph model to predict the risk of gout development.Methods:A total of 1 032 Han Chinese men attending the Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University, People′s Hospital of Xinjiang Uygur Autonomous Region, and the First Affiliated Hospital of Xinjiang Medical University from 2018 to 2020 were selected as study subjects and divided into training set(722 cases)and validation set(310 cases)by simple random sampling method in the ratio of 7∶3. General information and biochemical indices of the subjects were collected. The collected information was used to assess the risk of gout prevalence. LASSO regression analysis of R Studio software was used to screen the best predictors, and was introduced to construct a column line graph model for predicting gout risk using receiver operating characteristic(ROC)curves, and the Hosmer-Lemeshow test was used to assess the discrimination and calibration of the column line graph model. Finally, decision curve analysis(DCA)was performed using the rmda program package to assess the clinical utility of the model in validation data.Results:Age, uric acid, body mass index, total cholesterol, and waist-to-hip ratio were risk factors for gout( P<0.05). The column line graph prediction model based on the above five independent risk factors had good discrimination(AUC value: 0.923 for training set validation and 0.922 for validation set validation)and accuracy(Hosmer-Lemeshow test: P>0.05 for validation set validation); decision curve analysis showed that the prediction model curve had clinical practical value. Conclusion:The nomogram model established by combining age, uric acid, body mass index, total cholesterol, and waist-to-hip ratio indicators can predict the risk of gout more accurately.
