Firstly, the test results of each laboratory were statistically analyzed, and the precision of each laboratory was evaluated by the variation coefficient of indoor quality control. Secondly, the consistency was evaluated by comparing laboratories with different experimental platforms. The results showed that the passing rate of PAPP-A(pregnancy-associated plasma protein-A) precision test in 2021 and 2022 was 87.5% (7/8) and 92.3% (12/13), respectively. The accuracy pass rate of the Free β-hCG (free beta-human chorionic gonadotrophin)(early pregnancy) test in 2021 and 2022 was 97.5% (39/40) and 95.5% (42/44), and the accuracy pass rate of the AFP(alpha-fetal protein) test in 2021 and 2022 was 100% (40/40) and 90.9% (40/44), respectively. The accuracy pass rate of Free β-hCG (middle pregnancy) test in 2021 and 2022 was 100% (40/40) and 95.5% (42/44), respectively. The consistency of each index was 100%. In conclusion, the relevant data reported by laboratories carrying out serological prenatal screening in Jiangsu Province has a high consistency, and for a small number of laboratories with poor stability, it is necessary to make periodic evaluation and rectification according to the data analysis results, so as to improve the quality control management of maternal serological prenatal screening.

Background::There is a need for effective and safe therapies for psoriasis that provide sustained benefits. The aim of this study was to assess the efficacy and safety of tildrakizumab, an anti-interleukin-23p19 monoclonal antibody, for treating moderate-to-severe plaque psoriasis in Chinese patients.Methods::In this multi-center, double-blind, phase III trial, patients with moderate-to-severe plaque psoriasis were enrolled and randomly assigned (1:1) to receive subcutaneous tildrakizumab 100 mg or placebo at weeks 0 and 4. Patients initially assigned to placebo were switched to receive tildrakizumab at weeks 12, 16, and every 12 weeks thereafter. Patients in the tildrakizumab group continued with tildrakizumab at week 16, and every 12 weeks until week 52. The primary endpoint was the Psoriasis Area and Severity Index (PASI 75) response rate at week 12.Results::At week 12, tildrakizumab demonstrated significantly higher PASI 75 response rates (66.4% [73/110] vs. 12.7% [14/110]; difference, 51.4% [95% confidence interval (CI), 40.72, 62.13]; P <0.001) and Physician’s Global Assessment (60.9% [67/110] vs. 10.0% [11/110]; difference, 49.1% [95% CI, 38.64, 59.62]; P <0.001) compared to placebo. PASI 75 response continued to improve over time in both tildrakizumab and placebo-switching to tildrakizumab groups, reaching maximal efficacy after 28 weeks (86.8% [92/106] vs. 82.4% [89/108]) and maintained up to 52 weeks (91.3% [95/104] vs. 87.4% [90/103]). Most treatment-emergent adverse events were mild and not related to tildrakizumab. Conclusion::Tildrakizumab demonstrated durable efficacy through week 52 and was well tolerated in Chinese patients with moderate-to-severe plaque psoriasis.Trial registration::ClinicalTrials.gov, NCT05108766.

Objective To explore the correlation of CPNE3 expression with long-term prognosis of patients with gastric cancer(GC)and the possible mechanism.Methods We retrospectively collected the data of 104 GC patients undergoing radical surgery in our hospital from February,2013 to October,2017.TCGA database and immunohistochemistry were used to analyze CPNE3 expression level in GC tissues and its effects on tumor progression and long-term prognosis of the patients.GO analysis was performed to predict the biological role of CPNE3 in GC.We also conducted cell experiments with MGC803 cells and observed the effects of CPNE3 knockdown,CPNE3 overexpression and LY294002(a PI3K/AKT inhibitor)treatment on cell apoptosis and cellular expressions of apoptotic proteins using flow cytometry and Western blotting.Results TCGA analysis and immunohistochemistry both showed high expressions of CPNE3 in GC(P<0.05).The patients with high CPNE3 expressions had a reduced 5-year survival(P<0.01),and a high CPNE3 expression,CEA level≥5 μg/L,CA19-9 level≥37 kU/L,T3-T4 stage,and N2-N3 stage were all independent risk factors for a lowered 5-year survival rate after surgery.The sensitivity and specificity of CPNE3 for predicting 5-year mortality was 79.59%and 74.55%,respectively(P<0.05).GO analysis predicted that CPNE3 negatively regulated GC cell apoptosis.In MGC803 cells,CPNE3 knockdown significantly increased cell apoptosis,enhanced Bax and Cleaved Caspase-3 expressions and decreased Bcl-2 expression,while CPNE3 overexpression produced the opposite results(P<0.05).The cellular expressions of p-PI3K and p-AKT were significantly decreased following CPNE3 knockdown and increased following CPNE3 overexpression(P<0.05).Treatment with LY294002 obviously attenuated the inhibitory effect of CPNE3 overexpression on apoptosis of MGC803 cells(P<0.05).Conclusion CPNE3 is highly expressed in GC tissues and affects the long-term prognosis of the patients possibly by inhibiting GC cell apoptosis through activation of PI3K/AKT signaling.

Objective To analyze the expression level of ATP5A1 in gastric carcinoma and its influence on the prognosis of the patients and glucose metabolism in the tumor cells.Methods We retrospectively analyzed the data of 115 patients undergoing radical resection of gastric carcinoma in our hospital from February,2013 to November,2016.ATP5A1 expression in the surgical specimens were detected using immunohistochemistry,and the long-term prognosis of the patients with high(n=58)and low ATP5A1 expression(n=57)were analyzed.In gastric carcinoma MGC803 cells,the effects of lentivirus-mediated ATP5A1 knockdown or overexpression on glucose metabolism were investigated.We also observed the growth and glucose metabolism of xenografts derived from MGC803 cells with ATP5A1 knockdown or overexpression in nude mice.Results ATP5A1 was significantly overexpressed in gastric carcinoma tissues in close correlation with blood CEA and CA19-9 levels,pathological grade,T stage and N stage(P<0.05).ATP5A1 overexpression was an independent risk factor for a significantly lowered 5-year survival rate of patients with gastric carcinoma(P<0.05).ROC curve analysis demonstrated the predictive value of high ATP5A1 expression for the patients'prognosis(P<0.001).In MGC803 cells,ATP5A1 overexpression significantly up-regulated cellular glucose uptake and lactate production and increased the protein levels of HK2,PFK1,and LDHA(P<0.05),while ATP5A1 knockdown produced the opposite changes(P<0.05).In the tumor-bearing mice,overexpression of ATP5A1 increased glucose metabolism of the tumor cells and promoted tumor growth(P<0.05).Overexpression of ATP5A1 promoted the expressions of p-JNK and p-JUN in MGC803 cells(P<0.05),and the JNK inhibitor SP600125 significantly inhibited the enhancement of cellular glucose metabolism induced by ATP5A1 overexpression(P<0.05).Conclusion High ATP5A1 expression in gastric cancer is associated a poor long-term prognosis of the patients,and its effect is mediated at least partly by promoting glucose metabolism of the cells through the JNK/JUN pathway.

Background Photovoltaic (PV) cells can convert solar energy into electricity and alleviate the dilemma of energy supply shortage. Shanghai's PV module industry is booming, but there are few reports on the health status of the workers and there is an urgent need for health risk assessment. Objective To evaluate the health status of PV module production workers and the association between work and health status, in order to provide a direction for the health management of the workers. Methods Among the PV module production workers who completed prescriptive occupational health examination by a designated medical institution in 2021, 2453 workers with more than one year of working age were selected as the exposure group and 538 newly hired workers as the control group. On the basis of the Technical specifications for occupational health surveillance (GBZ 188−2014), the health examination included physical examination and laboratory examination and information such as sociodemographics, living habits, and disease history. We compared the indicators of pure-tone hearing test, blood routine examination, electrocardiogram (ECG), liver function, and kidney function between the two groups. The blood routine results included erythrocyte-related indicators, leukocyte-related indicators, and platelet-related indicators, and the results of liver function included hepatocyte injury indicators, hepatic secretory function indicators, and hepatic synthesis function indicators. The workers were divided into four groups by quartiles of working age. Trend chi-square test was used to analyze differences in health status between the four working age groups. Multiple logistic regression models were used to evaluate the association between working age and health indicators. Results Among the exposure group workers, 2035 (83.0%) were male and 418 (17.0%) were female. The median (P₂₅, P₇₅) age was 34.0 (30.0, 39.0) years and the median (P₂₅, P₇₅) working age was 6.0 (3.0, 10.0) years. The abnormality rate of blood routine was 61.7%. Among them, the abnormality rates of platelet-related indicators and liver secretory function indicators were 39.8% and 48.1% respectively. The risks of abnormal hepatocyte injury-related indicators, fatty liver, and platelet-related indicator abnormalities among the exposure group were 1.471 (95%CI: 1.060, 2.054), 1.691 (95%CI: 1.208, 2.385), and 7.576 (95%CI: 4.967, 11.994) times higher than those in the control group respectively. The single-factor analysis demonstrated a positively linear trend between working age and hypertension prevalence, electrical audiometry abnormality rate, or liver secretory function indicator abnormality rate. Corrected for gender, age, smoking status, hypertension, etc., the results of logistic analysis showed that quartile working age was positively related to abnormal liver secretion function and abnormal platelet-related indicators respectively (OR=1.047, P=0.005; OR=1.037, P=0.014), and inversely associated with the abnormal rate of renal function (OR=0.953, P=0.044). Conclusion Negative associations between health status and working age are identified in PV module production workers. The target PV module production employees are in younger age, and with the increase of working age, the abnormalities of liver function and platelets may increase. Therefore, the enterprises should extend occupational health work from workplace to workers.

Background Under the guidance of achieving carbon peaking and carbon neutrality goals, the demand for lithium-ion batteries has increased significantly. However, during the production, use, and maintenance of lithium-ion batteries, workers are inevitably exposed to various occupational hazards, and some chemicals are nephrotoxic. Objective To evaluate the kidney function and potential determinants among male workers in a lithium-ion battery-related enterprise in Shanghai. Methods The data of occupational health examination carried out by an occupational disease prevention and control institution for workers in a lithium-ion battery-related enterprise in Shanghai were collected. The workers participating pre-employment occupational health examination were treated as a control group, and the other group was recruited from those participating periodic health examination. Serum creatinine, urea nitrogen, uric acid, and renal ultrasound were used to assess the kidney function of workers. Kidney function was classified according to the reference range of kidney function indicators in Diagnostics (9th Edition, national planning textbook for high education in medicine). Binary logistic regression and generalized linear regression were used to identify potential determinants of abnormal values in kidney function indicators in workers. Results There were 6184 workers in the control group (pre-employment) with a mean age of (27.40±4.50) years. There were 3526 workers on the job with a mean age of (29.40±4.99) years and the median time of service was 2.00 (1.00, 3.42) years. The prevalence rates of high serum creatinine, high urea nitrogen, and high uric acid, and abnormal kidney ultrasound among the control group were 0.66%, 2.47%, 30.32%, and 10.12%, respectively; the indicators in the on-the-job workers were 0.96%, 3.35%, 38.25%, and 12.68%, respectively, significantly higher than those in the control group (P<0.05). After adjusting for worker age, length of service, smoking status, drinking status, hypertension, and hyperglycemia, the binary logistic regression models showed that regular smokers had a higher risk of high urea nitrogen than nonsmokers (OR=1.411, 95%CI: 1.011, 1.969). The risk of high uric acid was lower in older workers (OR=0.966, 95%CI: 0.953, 0.979), and higher in workers with more years of service (≤1 year, OR=1.295, 95%CI: 1.093, 1.534; >1-3 years, OR=1.747, 95%CI: 1.494, 2.042; >3 years, OR=1.866, 95%CI: 1.511, 2.304), hypertension (OR=1.400, 95%CI: 1.055, 1.859), and hyperglycemia (OR=1.565, 95%CI: 1.221, 2.006). Workers who were older (OR=1.038, 95%CI: 1.022, 1.054) and had longer working years (>1-3 years, OR=1.518, 95%CI: 1.201, 1.920), occasional smoking habits (OR=1.239, 95%CI: 1.039, 1.478), regular drinking habits (OR=1.875, 95%CI: 1.139, 3.087), and hypertension (OR=1.465, 95%CI: 1.075, 1.998) were at a higher risk of renal ultrasound abnormalities. The generalized linear models showed that length of service (>1-3 years, β=1.120, 95%CI: 0.360, 1.880; >3 years, β=1.451, 95%CI: 0.543, 2.358), smoking status (occasional, β=0.818, 95%CI: 0.156, 1.479; regular, β=0.841, 95%CI: 0.066, 1.616), and hypertension (β=2.742, 95%CI: 1.390, 4.094) were the influencing factors of serum creatinine concentration in the workers. Age (β=0.014, 95%CI: 0.009, 0.019) and length of service (>1-3 years, β=0.079, 95%CI: 0.012, 0.146) were the influencing factors of urea nitrogen. Age (β=−1.759, 95%CI: −2.288, −1.231), length of service (≤1 year, β=10.676, 95%CI: 4.035, 17.316; >1-3 years, β=26.117, 95%CI: 19.962, 32.272; >3 years, β=34.558, 95%CI: 26.116, 43.001), hypertension (β=23.162, 95%CI: 11.617, 34.707), and hyperglycemia (β=15.017, 95%CI: 4.853, 25.180) were the influencing factors of uric acid. Conclusion The prevalence of abnormal kidney function of workers in selected lithium-ion battery-related enterprise is varied by age, length of service, smoking status, drinking status, hypertension, and hyperglycemia. There may be a trend that the longer the time working in a lithium-ion battery-related enterprise, the worse the workers' kidney function. Therefore, the enterprise should pay attention to the possible reasons for their changes and take targeted interventions.

Objective: To analyze the impact of persistent obesity on their lung function, so as to offer insights for implementing intervention measures to increase lung function in obese school age children. Methods: A total of 335 children from the Sheyang Mini Birth Cohort established in 2009 in Yancheng City, Jiangsu Province, who participated in the follow up at the ages of 7 years (2016) and 10 years (2019), were selected as the study participants. Physical measurements including height, weight, and lung function were recorded. According to the World Health Organization standard, that is, gender and age specific to correct the body mass index to calculate the body mass index Z score, was used to evaluate the obesity status of children at the age of 7 and 10. Children were divided into four groups, including sustained non obesity group, restored obesity group, newly classified obesity group, and persistent obesity group. Meanwhile, the lung function prediction equations recommended by the Global Lung Function Initiative were used to standardize the lung function indexes of children. Pulmonary function differences among these groups were examined, and the relationship between childhood obesity and pulmonary function was longitudinally analyzed using generalized estimating equations. Results: The prevalence of obesity were 9.0% and 16.1% at the age of 7 and 10 years, respectively. The proportion of both newly classified and persistent obesity group were 8.1%, respectively. The forced expiratory volume in one second (FEV 1) and forced vital capacity (FVC) were (1 269.90±202.70) and (1 415.70±230.00) mL, respectively, at the age of 7 years. FEV 1 and FVC at the age of 10 years were (1 440.80±403.20) and (1 555.60±517.60) mL, respectively. Cross sectional analysis at age 7 showed that forced expiratory flow at 75% vital capacity (FEF 75 ) ( β=-0.52, 95%CI =-0.96--0.07) and maximal mid expiratary flow (MMEF) ( β=-0.45, 95%CI =-0.89--0.00) were significantly lower in obese children compared to their non obese peers ( P < 0.05). Longitudinal analysis indicated that obese children had lower levels of lung pulmonary function, with a statistically significant difference in FEV 1 ( β=-0.44, 95%CI=-0.85--0.02, P <0.05). There was no significant difference among the various obesity groups ( P >0.05), while gender stratified results revealed significant reductions in FEV 1/FVC in newly classified obese girls at age 10 years ( β=-1.76, 95%CI =-3.13--0.38) and in MMEF in persistently obese girls at age 10 years ( β=-1.44, 95%CI = -2.79- -0.09) ( P <0.05). Conclusion Obesity may contribute to reduced lung function levels in school aged children, with newly classified and persistent obesity having more pronounced effects on lung function in girls.
