Objective To investigate the association between the Chinese visceral adiposity index (CVAI) and diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension among elderly people in Hebei Province. Methods In 2020, a stratified multi-stage random sampling was used to conduct questionnaire survey, physical examination and laboratory detection among permanent residents of 10 monitoring sites in Hebei Province. Logistic regression was used to analyze the association between CVAI and diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension. The area under the ROC curve (AUC) was used to evaluate the predictive value of CVAI for diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension. Results The detection rates of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension were 19.8%, 74.6%, 78.2%, and 16.2%, respectively. Multivariate logistic regression analysis showed that compared with the lowest quartile of CVAI group Q1, the OR (95% CI) of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension in the highest quartile Q4 group were 3.55 (2.58~4.89), 2.52 (1.92~3.31), 3.09 (2.31~4.12), and 4.92 (3.40~7.12), respectively. The ROC curve results showed that CVAI had the best predictive value in the diagnosis of diabetes with hypertension, and the optimized critical values in males and females were 128.54 and 141.88, respectively. Conclusion The detection rates of diabetes mellitus and hypertension are high in the elderly population in Hebei Province. CVAI is positively associated with the risk of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension among the elderly in Hebei. CVAI has the strongest prediction ability for diabetes with hypertension.

Tumor immunotherapy occupies a pivotal position in the field of hematological malignancies.Chimeric antigen receptor(CAR)T-cell therapy has established a new therapeutic pattern for hematological immunotherapy and achieved satisfactory clinical results in the treatment of B-lineage hematological malignancies.However,CAR T-cell therapy has some limitations in the treatment of T-cell acute lymphoblastic leukemia because of the presence of CAR T-cell fratricide,tumor cell contamination,T-cell aplasia,and other clinically relevant problems.Therefore,the current major challenge is overcoming the existing bottlenecks to optimize CAR-T therapy and improve its efficacy against T-ALL while improving the prognosis of patients.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

Objective:To explore the clinical effects of intramuscular injection of oryzanol for 5 and 10 days in the treatment of menopausal syndrome.Methods:This study adopts a case-control study method.Twenty patients with menopausal syndrome admitted to Peking Union Medical College Hospital from July 2021 to March 2022 were selected and randomly divided into a control group and an observation group using a random number table method, with 10 patients in each group. The control group was given intramuscular injection of oryzanol once a day for 5 consecutive days on the basis of routine health education; On the basis of routine health education, the observation group was given intramuscular injection of oryzanol once a day for 10 consecutive days. Two groups of patients completed a total of 6 visits before treatment and on days 5, 10, 30, 60, and 90 of treatment. Baseline survey was conducted to record the basic information of patients, including demography data, menstruation, past history, surgical history, drug allergy and the main symptoms of climacteric syndrome, and the baseline hormone level of patients was detected. Compare the menopausal symptoms by modified K-score, Pittsburgh sleep quality index (PSQI) score, menopausal specific quality of life (MENQOL) score, post treatment injection site pain by visual analog score (VAS), and observe adverse reactions during treatment between the two groups of patients at each visit time point.The measurement data conforming to the normal distribution is expressed in xˉ± s. The comparison between the two groups is performed by t test, and the change trend of the two groups at each time point is compared by repeated measurement analysis of variance; The measurement data that do not conform to the normal distribution are represented by M( Q1, Q3), and the Kruskal Wallis test is used for comparison between groups; Counting data is represented by examples(%), Fisher's exact probability method is used for inter group comparison, and Wilcoxon rank sum test is used for rank data comparison. Results:The body mass of the control group was higher than that of the observation group [(62.50±11.88) kg vs (52.90±4.28) kg, t=2.40, P=0.027]. There was no statistical difference between the two groups in other demography data and previous history, sex hormone levels, menopausal symptoms, and menstrual conditions (all P>0.05). Compared with the baseline, the modified K-score, PSQI score, and MENQOL vascular dilation and contraction, psychological state, physiological state, and sexual life scores of the two groups of patients on the 5th, 10th, 30th, 60th, and 90th day of treatment were significantly reduced, and showed a gradually decreasing trend with the extension of observation time (the values in Group F were 36.37, 12.40, 18.69, 24.73, 40.77, and 18.39, respectively, P<0.001), but there was no statistically significant difference between the groups (all P>0.05). After treatment, the VAS score of the control group was 1 point in 2 cases, 2 points in 4 cases, and 3 points in 4 cases; The VAS score of the observation group was 1 in 4 cases, 2 in 3 cases, and 3, 5, and 6 in 1 case each. There was no statistically significant difference in VAS scores between the two groups ( Z=0.43, P=0.664), and no adverse events or serious adverse events were observed during the treatment period. Conclusions:Intramuscular injection of oryzanol injection for 5 and 10 days can improve menopausal symptoms, improve sleep quality and overall quality of life in patients with menopausal syndrome, and the overall effect is similar.

Objective: Subthreshold attention-deficit/hyperactivity disorder (ADHD) has been suggested to be a “morbid condition” which also needs medical attention. Methods: The present study recruited 89 children with subthreshold ADHD (sADHD), 115 children with diagnosed ADHD (cADHD), and 79 healthy controls (HC) to explore the clinical manifestation, executive functions (EFs) of sADHD, and the caregiver strain. The clinical manifestation was evaluated through clinical interviews and parent-reports. Executive functions were assessed both experimentally and ecologically. Caregiver strain was measured by a parent-reported questionnaire. Results: For the clinical manifestation, both sADHD and cADHD indicated impairments when compared with HC. The comorbidities and the scaled symptoms indicated that the externalizing behaviors were relatively less serious in sADHD than cADHD, whereas the internalizing behaviors between two groups were comparable. For ecological EFs, sADHD scored between cADHD and HC in inhibition and working memory. For experimental EFs, sADHD was comparable to cADHD in inhibition, shifting, and was worse than cADHD in verbal working memory. For the caregiver strain, all scores of sADHD were between that in cADHD and that in HC. Conclusion Our present findings supported the suggestion of subthreshold ADHD as “morbid condition,” which should be treated with caution in clinical practice, especially for the internalizing behaviors and some key components of EFs.

Objective: To explore the facilitators and barriers of the implementation of evidence based mental health practice, in order to provide practical experience for promoting the development of evidence based mental health services in primary schools in China. Methods: Semi structured interviews were conducted with 4 education bureau managers, 8 school administrators, 7 classroom teachers, and 7 treatment providers after providing evidence based practice in 10 primary schools in Henan Province, China. Data was analyzed using thematic analysis. Results: Evidence based practice in primary schools faced multiple factors at the macro level, school level, and individual level. A total of 8 facilitators and 9 barriers were extracted. Among these factors, some factors were particularly striking. These included the "exclusion" of teacher title evaluation system, time conflict between practice and school schedule, stigmatization of mental health and mismatch between perceived effectiveness of services and expectations. Conclusion Evidence based mental health practice is feasible in Chinese schools. The implementation process needs to take full account of macro, school and individual multi level factors to move evidence based mental health services from theory and data to practice in China.

Objective To investigate the relationship between the CD 8 +T cells results of clinical automatic analysis platform and the CD8lowT and CD8highT cell subsets.Methods A total of 1316 cases of lymphocyte and flow cytometry data were collected from the First Affiliated Hospital of China Medical University from December 2015 to September 2016 by cross-sectional study. There were 287 cases of malignant tumor , 389 cases of autoimmune disease , 320 healthy people and 320 cases of HIV infection , then to get automatic analysis platform returns result of CD 8+T cell.FlowJo software was used to analyze the CD8low T and CD8high T lymphocyte subsets in the patients , and the results were compared with the results of CD8 +T cells returned by the clinical automatic analysis platform .Results The results of clinical returns CD8 +T cells were consistent with the results of CD 8high T cells in patients with different diseases , and were not exactly the same as the results of CD8lowT cells, and the difference was as follows:the results of CD8low T cells in HIV-infected patients were significantly lower than those of healthy people (56.2 ±42.0, 68.8 ± 45.9, cells/μl P<0.001), which were different from the clinical results of CD 8 +T cells.The results of clinical report of CD8 +T cells were statistically correlated with CD8high T cells and CD8low T cells, and the correlation between CD8 +T cells and CD8highT were higher than that of CD8lowT cells.There was a positive correlation between CD8low T cell count and CD4 +T cell count ( r=0.204, P<0.001) .CD8low T was significantly higher in patients on antiviral treatment than that in untreated group (58.3 ±43.9, 42.9 ± 26.5, cells/μl, P<0.001).After treatment for more than 2 years, the CD8lowT cells in patients with CD4<500 cells/μl were significantly lower than those in patients with CD 4>500 cells/μl (50.1 ±47.0, 66.3 ±46.6, cells/μl, P<0.001).Conclusions The clinical report of CD8 +T cells was consistent with the results of CD8highT cells, and there was a great difference between the results of CD 8lowT cells and the results of CD8 +T cells.CD8low T cells were significantly reduced in HIV infected patients , and CD8low T cells could be effectively reconstructed by antiviral therapy .

Objective Folate receptors ( FRs) , overexpressed on the surface of a variety of tumor cells , are potential targets for tumor targeting therapy .This study aimed to prepare an FR-mediated drug nanocarrier with folate conjugated pullulan acetate ( FPA) to target chemotherapeutic agents to FR-overexpressed tumor cells and investigate its tumor-suppressing effect in vitro. Methods The cytotoxicity of epirubicin-loaded FPA nanoparticles ( FPA/EPI NP) against HepG2 and Hela cells was evaluated by MTS assay.The HepG2 and Hela cells were divided into five groups to be treated with NPs (NP control), chlorpromazine, chloro-quine, amiloride, and folate, respectively, followed by detection of the fluorescence intensity by flow cytometry . Results FPA/EPI NP was successfully formulated into NPs , with the mean particle size of (268.5 ±12.0) nm, by dialysis with an almost spherical shape . The drug-loading rate and entrapment rate of FPA/EPI NP were (6.45 ±1.04) and (72.45 ±11.50) %, respectively.The survival rates of the HepG2 and Hela cells were both >95%after 24 hours of incubation with FPA NP at 5, 40, 200, 400 and 1000μg/mL and 90.0%after 72 hours.The survival rates of the HepG2 cells treated with 5, 40, 200, 400 and 1000μg/mL FPA/EPI NP for 24 hours were (92.3 ±5.2), (70.4 ±4.6), (50.0 ±4.0), (41.1 ±4.1) and (27.0 ±3.6) %, respectively.Compared with the NP control group, the Hela cells of the chlorpromazine , amiloride and folate groups showed a significantly lower rate of NP uptake (P<0.05), and so did the HepG2 cells pretreated with chlorpromazine or amilo-ride (P<0.05).At 72 hours, the half maximal inhibitory concentrations (IC50) of FPA/EPI NP against HepG2 and Hela cells were 168 and 105μg/mL, respectively . Conclusion Clathrin-mediated endocytosis and macropinocytosis are involved in the internaliza-tion of FPA/EPI NP in HepG2 cells, while clathrin-and FR-mediated endocytosis in that of Hela cells .FPA NP may serve as a new drug carrier for tumor-targeted therapy .

3T3-L1 adipocytes transfected with TSH receptor (TSHR) shRNA were incubated with bovine TSH.The concentration of tumor necrosis factor (TNF)-α in culture medium was measured by enzyme linked immunosorbent asssy.Protein level of insulin receptor substrate 1 (IRS-1) was quantified by Western blotting.Tyrosine phosphorylation of IRS-1 was measured by immunoprecipitation.The results showed that 1 mIU/ml TSH significantly sitmulated TNF-α release in 3T3-L1 adipocytes [(341.85 ± 12.00 vs 522.67 ± 36.22) ng/L,P＜0.01],along with the decreases in IRS-1 protein expression and its tyrosine phosphorylation (P＜ 0.01).These effects disappeared when TSHR expression was down-regulated with RNA interference in 3T3-L1 adipocytes.In addition,WP9QY,a TNF-α antagonist,blocked TSH-decreased IRS-1 expresssion.These results suggest that TSH downregulates IRS-1 protein expression and its tyrosine phosphorylation through stimulating production of TNF-α,and thus contributes to the development of insulin resistance.
