ObjectiveTo explore the possible mechanisms of Wenyang Huazhuo Formula （温阳化浊方， WHF） in improving reproductive aging from the perspective of the ovarian mechanical microenvironment. MethodsThe experiment included five groups， 3-month group （20 female mice at 3 months of age）， 6-month group （20 female mice at 6 months of age）， 6-month + WHF group （20 female mice at 5 months of age treated with WHF）， 9-month group （20 female mice at 9 months of age）， and 9-month + WHF group （20 female mice at 8 months of age treated with WHF）. The 6-month + WHF group and 9-month + WHF group were orally administered WHF 41.2 g/（kg·d） once daily for 4 consecutive weeks. The other three groups received no intervention. Reproductive hormone levels were measured by ELISA. HE staining was used to count the numbers of various stages of follicles. Ovarian hyaluronic acid （HA） content and collagen fiber content were measured to evaluate the ovarian mechanical microenvironment. Superovulation was performed to observe the number of eggs obtained， as well as the number of offspring and birth weight to assess fertility. The in vitro fertilization and blastocyst culture of oocytes from female offspring in each group were observed to evaluate the effect of WHF on offspring reproductive potential. ResultsCompared with the 3-month group， the 6-month group and 9-month group showed significantly decreased serum levels of gonadotropin-releasing hormone （GnRH）， follicle-stimulating hormone （FSH）， and luteinizing hormone （LH）， decreased ovarian collagen content， and reduced numbers of primordial and secondary follicles. In contrast， the numbers of primary follicles， antral follicles， and atretic follicles increased. The levels of anti-Müllerian hormone （AMH）， ovarian HA content， and the fertilization rate， cleavage rate， and blastocyst formation rate of oocytes from offspring were significantly lower （P＜0.05）. Compared with the 6-month group， the 6-month + WHF group showed significantly reduced serum levels of GnRH， FSH， and LH， with a significant decrease in primary follicles， antral follicles， and atretic follicles as well as increase of AMH levels， ovarian HA content， number of primordial and secondary follicle， egg count， and offspring birth weight （P＜0.05）. Compared with the 9-month group， the 9-month + WHF group exhibited reduced GnRH， FSH， and collagen fiber content， as well as reduced number of primary follicles， antral follicles， and atretic follicles. However， AMH levels， ovarian HA content， number of primordial and secondary follicle， egg count， offspring numbers， birth weight， fertilization rate， cleavage rate， and blastocyst formation rate of oocytes from offspring all significantly increased （P＜0.05）. ConclusionWHF can significantly improve the ovarian reserve， fertility， and reproductive potential in offspring during reproductive mid-life and late-life stages. Its effect may be related to the remodeling of the mechanical microenvironment of aging ovaries. Moreover， the effect on the mechanical microenvironment remodeling of late-stage ovaries and the improvement of the offspring reproductive potential is more significant.

ObjectiveTo explore the establishment of performance assessment indicators for the classification and grading of public health staff in district-level Centers for Disease Control and Prevention (CDCs), and to provide a basis for such evaluations. MethodsThrough literature review and group interviews, performance evaluation indicators were developed based on competency evaluation. Experts were invited to evaluate the weight of performance evaluation indicators for public health staff from different categories, with the average value used to represent the weight of each indicator. ResultsTwenty-nine experts from universities in Shanghai, municipal CDCs, and district CDCs participated, yielding an expert authority coefficient of 0.86. The performance evaluation indicators for department managers were categorized into three levels, with 4 indicators at the primary level, 16 indicators at the secondary level, and 42 indicators at the tertiary level, while those for general staff included 4 primary indicators, 15 secondary indicators, and 36 tertiary indicators. Significant differences were observed in the weight coefficients of the primary indicators (internal operations, professional work, and learning and growth) between department managers and general staff. The top three secondary indicators for department managers were department management, monitoring and prevention, and level of expertise. For mid-level and senior staff, the top three secondary indicators were monitoring and prevention, level of expertise, and research work. The top three secondary indicators for junior staff were monitoring and prevention, professional expertise, and professional attitude. No significant statistical differences were found among tertiary indicators. ConclusionThe developed performance evaluation indicators are reliable. Staff at different levels and classifications should be evaluated using different performance evaluation standards to accurately reflect individual performance and contributions.

AIM: To explore the efficacy of bilateral lateral rectus recession in the treatment of basic intermittent exotropia. METHODS: A prospective study was conducted on 104 patients with basic intermittent strabismus admitted to our hospital from October 2022 to October 2023, patients were randomly divided into a study group of 52 cases and a control group of 52 cases using a random number ranking method. The control group received unilateral recess-resect, while the study group received bilateral lateral rectus recession, the differences in surgical success rate, postoperative strabismus, and postoperative exotropia drift were compared between two groups.RESULTS: There was no statistically significant difference between the two groups at 1 d, 1, 3, and 6 mo after surgery(all P>0.05). The strabismus in the 6 m and 33 cm eye positions at 1, 3, and 6 mo after surgery were lower than those at 1 d after surgery(all P<0.05). However, there was no statistically significant difference in the strabismus in the 6 m and 33 cm eye positions between the two groups at 1 d, 1, 3, and 6 mo after surgery(all P>0.05), and there was statistical significant difference between the two groups in exotropia drift at different postoperative time points(all P<0.05). The exotropia drift of both groups increased at 3 and 6 mo after surgery compared to 1 mo after surgery, and the exotropia drift at 6 mo after surgery was greater than that at 3 mo after surgery(all P<0.05). However, the exotropia drift of the study group at 3 and 6 mo after surgery was lower than that of the control group(all P<0.001). CONCLUSION: Bilateral lateral rectus recession for the treatment of basic-type intermittent exotropia effectively reduces the amount of postoperative exotropia drift, and it has better long-term stability.

ObjectiveTo investigate the ability of the modified albumin-bilirubin （mALBI） grade in predicting the prognosis of patients with Child-Pugh A unresectable hepatocellular carcinoma （uHCC） after transcatheter arterial chemoembolization （TACE） combined with immunotherapy and anti-angiogenic drugs （hereafter referred to as targeted immunotherapy）. MethodsA retrospective analysis was performed for the data of 76 patients with Child-Pugh A uHCC who met the inclusion criteria and underwent TACE combined with targeted immunotherapy in The First Affiliated Hospital of Soochow University from January 2020 to January 2023， and according to the mALBI grade， they were divided into mALBI 1/2a group with 38 patients and mALBI 2b group with 38 patients. The primary endpoint was overall survival （OS）， and the secondary endpoints were progression-free survival （PFS）， objective response rate （ORR）， and disease control rate （DCR）. Evaluation criteria included complete remission， partial remission， stable disease， and progressive disease. The independent-samples t test was used for comparison of normally distributed continuous data between groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between groups； the chi-square test was used for comparison of categorical variables between two groups. The Kaplan-Meier method was used to plot survival curves， and the Log-rank test was used for comparison of median OS （mOS） and median PFS （mPFS） between groups. The univariate and multivariate Cox proportional hazards models were used to analyze the influencing factors for prognosis. ResultsThere were significant differences in albumin and tumor burden between the two groups （both P<0.05）. The 76 patients had an mOS of 25.2 months （95% confidence interval ［CI］： 18.4 — 32.0）， an mPFS of 9.4 months （95%CI： 7.1 — 11.7）， an ORR of 63.2%， and a DCR of 82.9%. The mOS was 30.1 months （95%CI： 19.8 — 40.4） in the mALBI 1/2a group and 19.5 months （95%CI： 7.1 — 31.9） in the mALBI 2b group， and there was a significant difference in mOS between the two groups （χ²=4.490， P=0.034）. The mALBI 1/2a group had an mPFS of 10.2 months （95%CI： 8.4 — 12.0）， an ORR of 71.1%， and a DCR of 86.8%， while the mALBI 2b group had an mPFS of 7.6 months （95%CI： 4.6 — 10.6）， an ORR of 55.3%， and a DCR of 78.9%； there were no significant differences in mPFS， ORR， and DCR between the two groups （all P>0.05）. ECOG status， tumor burden， mALBI grade， portal vein invasion， and extrahepatic metastasis were independent risk factors for mOS in patients undergoing TACE combined with targeted immunotherapy （all P<0.05）. There were no treatment-related deaths. ConclusionThe mALBI grade has a good value in predicting the survival of patients with Child-Pugh A uHCC undergoing TACE combined with targeted immunotherapy.

Tumor immune microenvironment is a local external tumor environment composed of tumor immune cells and the cytokines secreted by these cells， and it plays a regulatory role in the development and progression of tumors. In the treatment of hepatocellular carcinoma， amino acid metabolism and its reprogramming of proliferating cell metabolism have attracted more and more attention， showing potential in regulating the tumor immune microenvironment. Although amino acid metabolic reprogramming is regarded as a novel approach for tumor therapy， its specific mechanism remains unclear in the regulation of tumor immunity in hepatocellular carcinoma. This article discusses the mechanism of action of amino acid metabolism in the tumor immune microenvironment of hepatocellular carcinoma and its application prospect in clinical practice， in order to provide new ideas for immunotherapy for liver cancer.

Objective To analyze the current situation of healthcare-associated infection (HCAI) management of fever clinics among different levels of medical institutions in Wuhan, and to provide a scientific basis for improving hospital infection management. Methods In January 2023, a network questionnaire survey was conducted on medical institutions with fever clinics in Wuhan. Results A total of 72 medical institutions were investigated, of which 58.33% had CT, and 48.61% had fever clinics for children. The total qualified rate of HCAI management was 78.28%. The qualified rates of four primary indicators, including hospital management, diagnosis and treatment environment protection, training and education, and implementation of infection control measures, were 82.27%, 71.49%, 75.93%, and 81.31%, respectively. There were statistical differences among different levels of medical institutions (all P<0.01). Among the 13 secondary indicators, the qualified rates of 7 indicators were more than 80%, with the highest being medical item management (93.06%), medical waste disposal (89.72%), and personnel management (83.33%), and the lowest being facilities and equipment (66.32%), and patients and accompanying personnel education (66.67%). Among the 65 tertiary indicators, 30 had a pass rate great than 80%. Conclusion Wuhan actively promotes the construction of fever clinics in medical institutions, and the overall situation of HCAI management is good. However, there are still some problems to varying degrees, especially in the layout procedures, hand hygiene, and staff training of fever clinics in secondary and lower medical institutions, which should be further strengthened.

ObjectiveTo explore the distribution characteristics of traditional Chinese medicine （TCM） syndrome elements of macroangiopathy in patients with type 2 diabetes mellitus （T2DM） and the key elements of occurrence， development and progression of disease. MethodsA multicenter cross-sectional study was conducted to enroll 445 T2DM patients from five hospitals， and according to the presence or absence of macroangiopathy， the patients were divided into a T2DM group （120 cases） and a diabetic macroangiopathy （DM） group （325 cases）. Patients in DM group were divided into grade Ⅰ， Ⅱ， Ⅲ and Ⅳ according to the peripheral vascular color Doppler ultrasound results and the vascular anomalies classification standard. The general data including gender， age， duration of T2DM and body mass index （BMI） were collected， and the data of four examinations were obtained for syndrome differentiation. According to the diagnostic criteria of TCM syndrome elements， the patients can be divided into 9 patterns including qi deficiency， blood deficiency， yin deficiency， yang deficiency， qi stagnation， blood stasis， excess heat， and excess cold. The general data and distribution of TCM syndrome elements were compared between the two groups. The distribution of TCM syndrome elements in different vascular anomalies grades in the DM group was analyzed. Logistic regression analysis was used to explore the influence of various TCM syndrome elements on the occurrence of macroangiopathy in T2DM. ResultsThere was no significant difference in gender and BMI between groups （P＞0.05）. The age and duration of diabetes in the DM group were older and longer than those in the T2DM group （P＜0.01）. With the increase of age and prolonged course of disease， the severity of diabetic macroangiopathy increases gradually （P＜0.05 or P＜0.01）. There was no significant difference in BMI and course of disease among the different TCM syndrome elements （P＞0.05）. The average age of patients with blood stasis syndrome was the oldest （P＜0.05）. There was significant difference in gender distribution between the excess heat syndrome and yin deficiency syndrome （P＜0.05）. A total of 240 TCM syndrome elements were extracted from the T2DM group， while 731 TCM syndrome elements extracted from the DM group. The top two high-frequency syndrome elements in the two groups were qi deficiency and yin deficiency， with a frequency of larger than 50%. The distribution of phlegm-damp syndrome and blood-stasis syndrome were significantly higher in the DM group than in the T2DM group （P＜0.01）. There were significant differences in the distribution of qi deficiency syndrome， yin deficiency syndrome， phlegm-damp syndrome， blood stasis syndrome， and excess heat syndrome among different grades of vascular anomalies （P＜0.01）； qi deficiency and yin deficiency were both high-frequency TCM syndrome elements in patients at grades 0 to Ⅲ； phlegm-damp syndrome increased in frequency with the progression of the disease from grades 0 to Ⅳ， and the frequency of blood stasis syndrome showed an overall upward trend. The frequency of phlegm-dampness syndrome increased from grades 0 to Ⅳ with the progression of the disease， and the frequency of blood stasis syndrome showed an overall upward trend. Logistic regression analysis showed that phlegm-damp syndrome and blood stasis syndrome were important TCM syndrome elements related to the vascular anomalies degree of macrovascular disease in T2DM （P＜0.05 or P＜0.01）. ConclusionQi deficiency and yin deficiency are the basic TCM syndrome elements throughout the whole process of T2DM and diabetic macrovascular disease. Phlegm-damp and blood stasis are related to the degree of vascular anomalies in diabetic macrovascular disease and are the key TCM syndrome elements in the progression of macroangiopathy in T2DM.

OBJECTIVE To explore the pharmacodynamic related substances and mechanism of Weining San(WNS) against gastric ulcer(GU) according to fingerprint and network pharmacology. METHODS Twelve batches of WNS fingerprints were established by HPLC, and methodological investigation was carried out. Combined with reference substances, characteristic peaks were identified, pharmacodynamic related substances were screened, and network pharmacological analysis was carried out. Using TCMIP and Swiss Target Prediction database to retrieve component targets; Using OMIM, GeneCards and Drugbank databases to retrieve GU disease targets, taking the intersection targets of components and diseases, using String database to construct protein-protein interaction network diagram, and analyzing topological parameters; Using Cytoscape 3.8.2 software to construct "component-disease-target" network diagram; GO and KEGG enrichment analysis of intersection targets were carried out by Metascape website. Then the alcoholic GU mouse model was established by intragastric administration of absolute ethanol to verify the results of network pharmacology prediction. RESUITS　The precision, stability and repeatability of HPLC fingerprint method were good. By comparison and comprehensive analysis of control substances, notoginsenoside R1, ginsenoside Rg1, militarine, ginsenoside Rb1, schisandrin, schisandrol B, deoxyschizandrin and schisantherin A were identified as pharmacodynamic related substances in WNS, which may play their role by regulating core targets such as AKT1, IL-6, STAT3, TNF, IL1B and key signal pathways such as PI3K-Akt and JAK-STAT. The gastric ulcer index, ulcer inhibition rate and HE staining showed that WNS could improve gastric mucosal injury in GU mice. The results of ELISA, WST-1 and TBA showed that WNS could decrease the levels of TNF-α, IL-6, IL-1β and MDA, and increase the levels of SOD and PGE2, suggesting that the anti-GU effect of WNS was related to the inhibition of inflammatory reaction and oxidative stress mechanism, which further verified the prediction of network pharmacology. CONCLUSION This study combines fingerprint analysis, network pharmacology, and animal experimental validation to explore the pharmacodynamic related substances and mechanisms of WNS anti-GU efficacy, providing reference for quality control and clinical research of WNS.

Objective To analyze serum characteristics and determine the reference range for thyroid function among healthy 11～16 year-old teenagers in Xi'an in order to offer a theoretical basis for clinical diagnosis and therapy.Methods A sum of 1 378 healthy 11～16 year-old teenagers who met the inclusion criteria from the First Affiliated Hospital of the Air Force Medical University(Xijing Hospital)between January 2020 and December 2022 were selected as research subjects,including 628 males and 750 females.They were divided into three groups based on age:Group 1:11～＜13 year-olds(433 cases),Group 2:13～＜15 year-olds(425 cases),and Group 3:15～≤16 year-olds(520 cases).Differences in serum thyroid function indices among different genders and age groups were analyzed,the reference ranges for these indices were established,and 99 healthy 11-16 year-old teenagers who met the inclusion criteria were chosen for verification.Results There were no significant differences between different genders in thyroid stimulating hormone[TSH,2.56(1.80,3.63)μIU/ml vs 2.43(1.68,3.48)μIU/ml]and total thyroxine[TT4,97.84(85.34,111.00)nmol/L vs 98.20(87.16,111.23)nmol/L],the differences were statistically significant(Z=-1.881,-0.638,all P＞0.05).Meanwhile,the differences in free thyroxine[FT4,16.93(15.49,18.60)pmol/L vs 16.26(14.80,17.83)pmol/L],free triiodothyronine[FT3,6.21(5.66,6.80)pmol/L vs 5.59(4.98,6.19)pmol/L],and total triiodothyronine[TT3,2.24(1.96,2.55)nmol/L vs 2.04(1.78,2.34)nmol/L]between different genders were significant(Z=-5.368,-11.994,-6.417 all P＜0.01).The differences in thyroid function indices were significant among different age groups(Z=10.649～261.003,all P＜0.05).The reference ranges for thyroid function indices across different age groups and genders were established,in which thyroid function indicators were verified to be within the established reference range by 99 samples.Conclusion Teenage hormone secretion varies greatly,and the secretion of thyroid hormones is influenced by various factors.Thus,the diagnosis and treatment of teenage thyroid diseases cannot fully rely on the reference ranges provided by adults or manufacturers.This study established the reference range of the thyroid function indices of 11～16 year-old teenagers in Xi'an,offering clinical doctors'diagnosis and treatment data support.
