Polycystic ovary syndrome （PCOS） is one of the most prevalent gynecological diseases， and its incidence is increasing year by year， seriously affecting the physical and mental health of female patients. The pathogenesis of this disease is complex and has not been fully clarified. At present， PCOS is mainly treated by Western medicine， which， however， has poor efficacy and induces various adverse reactions. Therefore， developing safe and effective therapies has become a difficult problem that needs to be solved. Studies have confirmed that traditional Chinese medicine （TCM） can regulate phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt）， mitogen-activated protein kinase/extracellular signal-regulated kinase （MAPK/ERK）， Toll-like receptor 4/nuclear factor-κB （TLR4/NF-κB）， transforming growth factor-β （TGF-β）/Smads， secreted glycoprotein/β-catenin （Wnt/β-catenin）， adenosine monophosphate-activated protein kinase （AMPK）， and advanced glycation endproduct/receptor for advanced glycation endproducts （AGE/RAGE） signaling pathways to ameliorate insulin resistance， inhibit inflammation and oxidative stress， regulate endocrine hormone disorders， and intervene in apoptosis and autophagy， thus alleviating the symptoms， slowing down the disease progression， and improving the ovarian function. The treatment of PCOS with TCM has demonstrated definite effects and high safety. Therefore， exploring this disease from cellular and molecular perspectives can provide a theoretical basis for its clinical treatment and new drug development. However， there is a lack of systematic reviews on the modulation of relevant signaling pathways by TCM in the treatment of PCOS. This article reviews the research progress in the treatment of PCOS with the active ingredients and compound prescriptions of TCM by regulating relevant signaling pathways in recent years， with the aim of providing evidence to support the promotion of TCM for treating PCOS in the future.

Background Schizophrenia patients are often accompanied by negative symptoms and severe cognitive impairment,but effective interventions intended to alleviate such condition are currently limited.Existing researches on group play therapy for schizophrenia is still in its initial stages,and such therapy has the potential to contribute to symptoms improvement.Objective To explore the efficacy of group play therapy on improving cognitive function and negative symptoms in hospitalized female patients with schizophrenia,so as to provide references for clinical intervention in such group.Methods This study involved 40 female patients with schizophrenia who received inpatient treatment at the Third People's Hospital of Fuyang from April 2022 to May 2023 as well as met the diagnostic criteria of the International Classification of Diseases,tenth edition(ICD-10).They were divided into study group(n=20)and control group(n=20)according to the random number table method.Both groups received routine treatment,and the study group received 10 sessions of group play therapy for 5 weeks on the basis.At baseline,Scale for Assessment of Positive Symptoms(SAPS),Scale for Assessment of Negative Symptoms(SANS),Self-rating Depression Scale(SDS),Nurses' Observation Scale for Inpatient Evaluation(NOSIE),and Repeatable Battery for the Assessment of Neuropsychological Status(RBANS)were used for assessment.Post-therapy evaluation was conducted by using SAPS,SANS and RBANS.Patients' baseline SAPS scores,SANS scores,RBANS total scores,and various factor scores of RBANS were used as covariates,and covariance analysis was adopted to compare the scores of each scale between the two groups after treatment.Results A total of 39 patients went through the whole study.Results of covariance analysis showed that the SANS score of study group was lower than that of control group,while several scores of RBANS(including total score,immediate memory factor score,speech function factor score and attention factor score)were all higher than those in control group.Significant difference was observed between two groups in scores of both scales above(F=13.408,10.331,4.932,9.967,10.010,P<0.05 or 0.01).Conclusion Group play therapy may help improve negative symptoms and cognitive function in hospitalized female patients with schizophrenia.

Objective:To explore the effects of phased goal directed fluid therapy (GDFT) during anesthesia surgery on tissue perfusion and cognitive function in patients undergoing radical lung cancer surgery.Methods:A total of 108 lung cancer patients were prospectively selected and randomly divided into a control group and a study group using a random number table method. The control group received classical restrictive liquid therapy, while the study group received staged GDFT. We compared the surgical time, intraoperative blood loss, colloid fluid dosage, crystalloid fluid dosage, total output, and urine volume between two groups of patients; Two groups of patients were compared in terms of oxygenation index (OI), respiratory index (RI), central venous oxygen saturation (ScvO 2), lactate (Lac), central venous arterial carbon dioxide partial pressure difference (Pcv-aCO 2), oxygen supply index (DO 2I), and oxygen uptake rate (O 2ERe) before anesthesia induction (T 0), before single lung ventilation (T 1), 1 hour of single lung ventilation (T 2), immediate resumption of dual lung ventilation (T 3), 30 minutes of dual lung ventilation (T 4), and after surgery (T 5); The Mini Mental State Examination (MMSE) was used to evaluate the cognitive function scores of two groups of patients 1 day before surgery and 1 and 3 days after surgery, while recording the incidence of cognitive dysfunction (POCD) and pulmonary complications (including pulmonary infection, acute lung injury, pulmonary embolism, pulmonary edema, atelectasis, etc.) within 3 days after surgery. Results:The amount of crystal fluid and urine output in the research group was significantly lower than that in the control group, while the amount of colloidal fluid was significantly higher than that in the control group (all P<0.05). The OI of the study group T 1-T 5 was significantly higher than that of the control group, while the RI of T 2-T 5 was significantly lower than that of the control group (all P<0.05). The ScvO 2 of the study group T 1 to T 5 was significantly higher than that of the control group, and the Lac was significantly lower than that of the control group (all P<0.05); The MMSE scores of both groups of patients were significantly lower than those before surgery on day 1 and 3 after surgery, and the MMSE scores of the study group were significantly higher than those of the control group on day 1 and 3 after surgery (all P<0.05). The incidence of POCD within 3 days after surgery in the study group was 16.67%(9/54), lower than 37.04%(20/54) in the control group (χ 2=5.704, P=0.017); The incidence of pulmonary complications in the study group was lower than that in the control group (5.56% vs 22.22%, χ 2=4.955, P=0.026). Conclusions:The application of staged GDFT during anesthesia in patients undergoing radical lung cancer surgery can further improve tissue perfusion, improve microcirculation and oxygen supply-demand balance of systemic organs and tissues, including the brain, alleviate perioperative brain function damage, and reduce the occurrence of postoperative POCD compared to conventional liquid therapy.

Objective: To explore the association between lifestyle and fat mass index (FMI) in different positions of children and adolescents aged 7-18, so as to provide a scientific basis for health promotion in children and adolescents. Methods: A total of 1 531 students aged 7-18 was selected by intentional sampling from 4 schools in Tongzhou District, Beijing from September to December in 2020 and August in 2022. Questionnaire survey was used to collect lifestyle including dietary behavior, moderate to vigorous physical activity, smoke and drink behaviors, sleep time and sleep quality. Dual energy Xray absorptiometry was employed to assess fat mass, and calculated total, android, trunk, hip, gynoid and leg fat mass index (FMI). The ttest and Chisquare test were used to compare the differences of different lifestyle. Logistic regression was used to analysis association between lifestyle and body composition in different positions. Results: Compared with healthy lifestyle, unhealthy lifestyle had higher risk for hightrunk FMI (OR=1.40, P<0.05). After adjusted for sex and age, unhealthy lifestyle had higher risk for hightotal FMI, highandroid FMI, hightrunk FMI (OR=1.37, 1.37, 1.50, P<0.05), compared with healthy lifestyle. Stratified analysis found the associations between unhealthy lifestyle and hightotal FMI, highandroid FMI, hightrunk FMI, and highthigh FMI were only significant in girls with 7-12 years old (OR=2.13, 2.46, 2.13, 2.13, P<0.05). Conclusions Unhealthy lifestyle is associated with hightotal FMI, highandroid FMI and hightrunk FMI. A healthy lifestyle should be maintained during puberty, especially before puberty, to help children and adolescents reduce body fat and promote a balanced distribution of body composition.

Objective:To explore the clinical and genetic characteristics of two children with Neurodevelopmental disorders (NDDs) due to variants of TANC2 gene. Methods:Clinical data of two children who were admitted to the Third Affiliated Hospital of Zhengzhou University respectively in April 2020 and April 2021 were retrospectively analyzed. Peripheral blood samples of the children and their parents were collected and subjected to whole exome sequencing. Candidate variants were verified by Sanger sequencing. By using " TANC2 gene", "Neurodevelopmental disorders", "Nervous system development disorders", " TANC2" as the key words, similar cases were searched from the CNKI, Wanfang database platform and PubMed database, with the search time set as from the establishment of the database to December 2023. This study was approved by Medical Ethics Committee of the Third Affiliated Hospital of Zhengzhou University (Ethics No. 2020-57). Results:Case 1 was a 1-year-and-3-month-old girl who had developed convulsions at 1 year old and had three episodes of seizures. Her epilepsy had resolved with the treatment of oxcarbazepine, which was stopped at the age of 2-year-and-7-month. Her language, movement and intelligence development were all normal. Case 2 was a 1-year-and-10-month-old boy, who had developed convulsions at 1 year old. His seizure type was myoclonus, and the frequency was dozens of times a day. His epilepsy had resolved with the treatment of sodium valproate. His language, movement and intelligence development was delayed for about half a year. Genetic analysis showed that both children had harbored novel variants of the TANC2 gene (NM_025185.4), including c. 3398G>A (p.Gly1133Glu) and c.2829+ 1G>A, respectively. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the former was rated as likely pathogenic (PS2+ PM2_Supporting+ PP3) and the latter was rated as pathogenic (PVS1+ PS2+ PM2_Supporting). Two previous reports were retrieved, which had involved 17 cases and 16 variants. Common features had included autism spectrum disorder (70.6%, 12/17), intellectual disability (94.1%, 16/17), language and motor retardation (88.2%, 15/17; 58.8%, 10/17), facial dysmorphism, epilepsy, ataxia, and thoracic and spinal deformities. Conclusion:Variants of the TANC2 gene probably underlay the epilepsy and development delay in these children with NDDs.

Objective To analyze the risk factors of heart failure in patients with coronary heart disease(CHD),and to construct and verify a nomogram prediction model for the risk of heart failure in patients with CHD.Methods The clinical data of 453 patients with CHD who were hospitalized in the Second Affiliated Hospital of Shenyang Medical College from January to December 2022 were retrospectively analyzed,including 278 patients with CHD combined with heart failure and 175 patients without heart failure.The patients were divided into training group(318 cases)and validation group(135 cases)according to the ratio of 7:3.R software was applied to perform LASSO regression to screen the risk factors,and Logistic regression to establish a prediction model and construct a nomogram.The calibration curve and receiver operating characteristic(ROC)curve were used to evaluate the calibration and discrimination of the model.Results LASSO regression analysis ultimately screened five risk factors from 22 variables,and Logistic regression results showed that age,smoking,history of myocardial infarction,New York Heart Association(NYHA)cardiac function class Ⅳ,and left ventricular ejection fraction(LVEF)were all independent risk factors for heart failure in CHD patients(P＜0.05).The model formula was Z=-2.927+0.045 × age+0.886 × smoking+0.808 × history of myocardial infarction-2.829 × NYHA cardiac function class Ⅳ+0.037×LVFF.Internal validation of the model showed that area under the curve was 0.727(95％CI:0.588-0.752),the sensitivity was 40.4％,the specificity was 84.3％,and the Youden index was 0.247.According to the calibration curve,the predicted value of the calibration curve was highly consistent with the actual value,and the Brier score was 0.106.Conclusion The risk prediction model for heart failure in patients with CHD based on LASSO regression has good discrimination and prediction efficiency,which can be used as an evaluation tool for medical staff to predict the risk of patients.

Objective: To explore the association between digital devices usage and body weight overestimation in children and adolescents aged 7-18, in order to provide a scientific basis for body weight overestimation prevention in children and adolescents. Methods: Based on the data of the Research Special Project for Public Welfare Industry of Health using stratified cluster sampling method in 2012, a tatal of 40 073 children and adolescents from 7 provinces with complete information were chosen. Ordinal multivariable Logistic regression model estimated the association between digital devices usage and body weight overestimation. Results: A total of 4 276(11.8%) students with overestimation of body weight were detected, who spent >300 min/d time in digital devices(5.12%) than others (3.84%)( χ 2=19.14, P <0.01). Univariate analysis showed that students with time spent on digital devices >300 min/d had a higher risk in overestimation of body weight ( OR=1.36,95%CI=1.18-1.57,P <0.01) compared with students who spent on digital devices≤120 min/d. There was still a significant association after confounder adjustment ( OR=1.28, 95%CI= 1.10-1.48,P <0.05). Stratified analysis showed that the association between digital devices usage and overestimation of body weight were only observed in girls, 11-18 years old and non single child( P <0.05). Conclusion The time usage of digital devices is associated with overestimation of body weight in children and adolescents. It may helpful for children and adolescents to prevent overestimation of body weight by reducing time spent on digital devices.

Objective:To analyze the association between exposure to ambient PM 2.5 and its components [sulfate (SO 42-), nitrate (NO 3-), ammonium (NH 4+), organic matter (OM), and black carbon (BC)] and psychological distress among school children and adolescents aged 9 to 18 years in China. Methods:Based on data from the 2019 Chinese National Survey on Students' Constitution and Health, 130 808 children and adolescents aged 9 to 18 years were included. Scoring and determination of higher psychological distress were based on the Kessler Psychological Distress Scale (K10), and annual average exposure data for air pollution were matched by survey location and time. We used a restricted cubic spline approach based on logistic regression to fit the associations between PM 2.5, SO 42-, NO 3-, NH 4+, organic matter, black carbon concentrations, and psychological distress. Logistic regression models were used to analyse different age, gender, BMI and physical activity subgroups to estimate the association between exposure to high levels of pollution and high levels of psychological distress in different subgroups. Results:The proportion of children and adolescents with high levels of psychological distress in China was 30.4%, with girls being higher than boys at 31.6% and 29.1%, respectively ( P<0.05). A non-linear positive association existed between exposure to PM 2.5, SO 42-, NO 3- and organic matter concentrations and higher psychological distress. As PM 2.5, NO 3-, NH 4+, organic matter, and black carbon concentrations continued to rise, the increase in the risk of higher psychological distress slowed, while SO 42- showed little change in the OR of psychological distress at lower concentrations but continued to rise at higher concentrations. PM 2.5 and its components were statistically associated with psychological distress in the physically inactive group but not in the physically active group. The association between high levels of pollutants and high psychological distress was stronger among students aged 9 to 12 years compared with students aged 13 to 15 years and 16 to 18 years. Conclusions:The ambient pollutant PM 2.5 and its components are associated with psychological distress in children and adolescents aged 9 to 18 years in China. High pollutant exposure is a risk factor for high psychological distress among physically inactive children and adolescents, and there are age differences in the association between PM 2.5 and components and psychological distress.

Objective:To analyze the influencing factors of anesthesia recovery time after gastric cancer surgery in patients with type 2 diabetes mellitus (T2DM), and establish a nomogram model.Methods:The clinical data of 120 T2DM patients underwent open surgery for gastric cancer from February 2020 to January 2021 in Handan Central Hospital were retrospectively analyzed. Among them, 50 patients had an anesthesia recovery time>30 min (observation group), and 70 patients had an anesthesia recovery time≤30 min (control group). Multivariate Logistic regression was used to analyze the independent risk factors of anesthesia recovery time after gastric cancer surgery in patients with T2DM. Receiver operating characteristic (ROC) curve was drawn to analyze the optimal cut-off value of each influencing factor for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM. A nomogram model to predict anesthesia recovery time after gastric cancer surgery in patients with T2DM was established with R language software 4.0 "rms" package.Results:The proportion of men, age, decrease amplitude of postoperative temperature, operation time intraoperative blood transfusion rate in observation group were significantly higher than those in control group: 84.00% (42/50) vs. 20.00% (14/70), (60.31 ± 14.23) years vs. (47.58 ± 8.96) years, (0.33 ± 0.09) ℃ vs. (0.28 ± 0.08) ℃, (92.32 ± 8.58) min vs. (84.54 ± 6.24) min and 38.00% (19/50) vs. 10.00% (7/70), the body mass index (BMI), heart rate and operating room temperature were significantly lower than those in control group: (20.11 ± 3.96) kg/m 2 vs. (24.69 ± 4.58) kg/m 2, (103.73 ± 9.57) beats/min vs. (118.32 ± 18.15) beats/min and (28.66 ± 1.58) ℃ vs. (30.25 ± 1.98) ℃, and there were statistical differences ( P<0.01); there were no statistical differences in smoking, drinking, hypertension, hyperlipidemia, coronary heart disease, anesthetic drug types, anesthesiologist job title, muscle relaxant drug types and body temperature between 2 groups ( P>0.05). ROC curve analysis results showed that the optimal cut-off values of age, BMI, heart rate, decrease amplitude of postoperative temperature, operating room temperature and operation time for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM were 46 years old, 21.8 kg/m 2, 113 beats/min, 0.3 ℃, 30.6 ℃ and 91 min, respectively. Multivariate Logistic regression analysis results showed that gender (male), age (>46 years old), BMI (≤21.8 kg/m 2), decrease amplitude of postoperative temperature (>0.3 ℃), operating room temperature (≤30.6 ℃) and operation time (>91 min) were independent risk factors for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM ( OR = 1.909, 1.815, 1.606, 1.458, 1.521 and 1.539; 95% CI 1.215 to 3.000, 1.014 to 3.249, 1.252 to 1.941, 1.251 to 1.628, 1.068 to 2.167 and 1.119 to 1.828; P<0.01 or<0.05). When gender, age, BMI, decrease amplitude of postoperative temperature, operating room temperature and operation time were included as predictors for constructing the nomogram model, the internal validation results showed that the c-index of the nomogram model for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM was 0.701 (95% CI 0.672 to 0.724); calibration curve showed good agreement between observed value and predicted value; the threshold value of the nomogram model for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM was>0.20, and the nomogram model provided a net clinical benefit; the clinical net benefit of the nomogram model was greater than that of sex, age, BMI, decrease amplitude of postoperative temperature, operating room temperature and operation time. Conclusions:A nomogram model to predict anesthesia recovery time after gastric cancer surgery in patients with T2DM is constructed based on gender, age, BMI, decrease amplitude of postoperative temperature, operating room temperature and operation time, and this model is significant for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM.

Objective: To analyze the association between masculine and feminine traits, gender role in students and family factors, and to provide a scientific basis for promoting the healthy development of children and adolescents gender role. Methods: Cluster random sampling method was used to selected 823 students from 2 schools of Xiamen in May, 2018, participants were asked to report individual masculine and feminine traits through the Child s Sex Role Inventory, and then gender role was divided into four types (masculine, feminine, androgynous, undifferentiated). Non parametric tests, generalized linear model, and Logistic regression model were used to explore the association between masculine and feminine traits, gender role and family factors. Results: Compared with the boys from the nuclear family, the masculine traits were lower in boys of other families by 0.282( 95% CI = -0.452 --0.110), and the feminine traits were also lower by 0.192 (95% CI =-0.369--0.014). Compared with boys of middle socioeconomic status (SES), the masculine traits of boys from low SES decreased by 0.157 (95% CI =-0.286--0.029), and the feminine traits decreased by 0.140 (95% CI =-0.274--0.005). The proportion of androgynous in boys from other families was significantly lower than boys from the nuclear family ( OR =0.45, 95% CI =0.21-0.94), with the proportion of undifferentiated significantly higher than nuclear family 2.33 (95% CI =1.22-4.44). The proportion of androgynous in boys from low SES was significantly lower than boys from middle SES ( OR =0.59, 95% CI =0.35-0.99), with the proportion of undifferentiated significantly higher than middle SES 1.62 (95% CI =1.00-2.65). Among girls, the differences in masculine and feminine traits and gender role of different family factors were not statistically significant ( P >0.05). Conclusion The masculine and feminine traits and gender role in students are associated with family structures and socioeconomic status, especially in boys. Therefore, the family environment is an important factor affecting children s gender role, and the healthy development of children s gender role needs parents attention and correct guidance.
