Objective:To analyze the immunization status of routine vaccines for children aged 0-7 years old with special health status in Tianhe District, Guangzhou City, from 2023 to 2024.Methods:From April 2023 to March 2024, 42 vaccination units in Tianhe District, Guangzhou, were organized to collect data on diseases and vaccination history of children with special health status. Vaccination rates were calculated, and multivariate logistic regression models were used to explore the impact of special health status on vaccination rates.Results:A total of 1 976 children aged 0-7 years old with special health status were included, with an average of (1.26±0.58) diseases per participant. The average number of vaccine doses administered for routine immunizations was (14.29±4.27), and the full vaccination coverage was 72.76%. The vaccination rate of 10 doses in the immunization program vaccine was less than 90.00%. The timely rate of the first dose of hepatitis B vaccine (HepB1) was 74.14%, and that of the first dose of measles vaccine (MCV1) was 63.93%. Compared with children with infectious diseases, those with neonatal diseases were more likely to miss the third dose of poliomyelitis vaccine (PV3), MCV1 and the second dose of Group A meningococcal polysaccharide vaccine (MPSV-A2). Those with neuromuscular system diseases were more likely to miss PV3, MPSV-A2 and the first dose of Japanese encephalitis vaccine, live (JE-L1). Those with congenital heart disease were more likely to miss PV3, the third dose of diphtheria tetanus-acellular pertussis vaccine (DTaP3), MCV1, MPSV-A2, and JE-L1. Those with hematological disorders were more likely to miss PV3, MCV1, MPSV-A2, and JE-L1. Those with genetic diseases were more likely to miss MPSV-A2. Those with comorbidities were more likely to miss MCV1 and MPSV-A2. Those with neonatal diseases, neuromuscular system diseases, congenital heart disease, hematopoietic system diseases, genetic diseases, or comorbidities had difficulties in completing the full vaccination process.Conclusion:Children with special health conditions have lower rates of routine immunization and timely vaccination. More measures are needed to improve vaccination rates.

Objective To investigate the inhibitory effect of MKK6(E)fusion protein on the growth of o-varian cancer graft tumors in nude mice and its possible mechanism.Methods A subcutaneous transplantation tumor model in nude mice was constructed using subcutaneous injection of human ovarian cancer HO8910PM cells,which were divided into model group,paclitaxel(positive control,3 mg/mL)group,MKK6(E)fusion protein(1.2 mmol/L)group and MKK6(E)fusion protein+SB202190(p38 agonist,10 μmol/L)group by numerical randomization table,each with 6 animals.The drug was administered continuously in the tail vein for 21 d,once every 3 d.At the end of the administration,the tumor was exfoliated and the tumor volume,mass and tumor inhibition rate were calculated.Serum carbohydrate antigen(CA)125 level was detected by enzyme linked immunosorbent assay(ELISA),histopathology of the tumor was detected by HE staining,and apoptosis of the tumor cells was detected by TUNEL staining.In addition,expression of Fibronectin,matrix metallo-peptidase(MMP)2,and MMP9 were detected by immunohistochemistry,apoptosis and the p38/ATF-2 pathway-related proteins were detected by Western blot.Results Compared with the model group,the tumor volume,mass and serum CA125 level of nude mice in the paclitaxel group and the MKK6(E)fusion protein group were reduced,the tumor suppression rate and the apoptosis rate of cancer cells were increased,the volume of cancer cells in the transplanted tumor tissue was reduced,the nucleus was lightly stained,the di-viding heterogeneity was reduced compared with that of the model group,and the large area of lamellar nec-rotic zone and apoptotic cells were seen,and the expression of Fibronectin,MMP2 and MMP9 was reduced.Bax and Cleaved caspase 3 expression was up-regulated,and Bcl-2 expression and phosphorylated p38(p-p38)/p38 and p-ATF-2/ATF-2 were down-regulated(P＜0.05).Compared with the MKK6(E)fusion pro-tein group,nude mice in the MKK6(E)fusion protein+SB202190 group showed increased tumor volume,mass and serum CA125 levels,decreased tumor suppression and cancer cell apoptosis,better cancer cell status,decreased necrotic areas,increased expression of Fibronectin,MMP2 and MMP9,and down-regulated Bax and Cleaved caspase 3 expression was down-regulated,and Bcl-2 expression and p-p38/p38 and p-ATF-2/ATF-2 were up-regulated(P＜0.05).While p-ERK/ERK and p-JNK/JNK were compared among the 4 groups,the difference was not statistically significant(P＞0.05).Conclusion MKK6(E)fusion protein inhibits the growth of ovarian cancer subcutaneous graft tumors,and its mechanism may be related to the inhibition of p38/ATF-2 signa-ling pathway activation.

Objective: To analyze the regulatory effect of Atractylodes macrocephala Koidz. extract on the immune function of mice, so as to provide a reference for the study of the mechanism of Atractylodes macrocephala Koidz. regulating immune function. Methods: Forty-eight SPF healthy male ICR mice were randomly divided into control group and low (0.5 g/kg), medium (2.0 g/kg), and high (4.0 g/kg) dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day. The delayed allergy test was performed for 28 consecutive days. Sixty SPF healthy male ICR mice were randomly divided into a control group, polyinosinic acid injection group (model group), and low, medium, and high dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day for 14 consecutive days. On days 13 and 14 of administration, the mice in the model group and each dose group were intraperitoneally injected with sterile polyinosinic acid solution to perform the immunosuppressive experiment induced by polyinosinic acid. The mouse ear pieces were weighed, and the thymus and spleen of the mice were weighed and stained with HE to calculate the pathological scores. Peripheral blood was collected for blood cell detection and T cell classification. Results: Mice in each group had normal feeding, activity, and growth status, and no abnormality was observed. In the delayed allergy test, compared with the control group, the degree and rate of ear swelling in the low, medium and high dose groups were higher, the white blood cell count in the medium dose group was higher, and the absolute values of lymphocytes in the low and medium dose groups were higher (all P<0.05). Compared with the control group, the pathological scores of the thymus and spleen in the model group were higher (both P<0.05). In the immunosuppressive experiments in mice induced by polyinosinic acid, compared with the model group, the pathological score of the thymus in the high dose group was lower (P<0.05), and the boundary between the thymus cortex and medulla was improved. Conclusions Atractylodes macrocephala Koidz. extract can increase the degree of ear swelling and peripheral blood white blood cell count in mice. High dose of Atractylodes macrocephala Koidz. extract can improve the thymus injury induced by polyinosinic acid, and has an immunomodulatory effect.

Objective:To translate the Papua New Guinea Vision-Specific Quality of Life Questionnaire (PNG-VS QoL) into Chinese and test its reliability and validity.Methods:The Chinese version of PNG-VS QoL was developed through translation, back translation, cross-cultural adaption, and pre-survey. From July to September 2023, convenience sampling was used to select visually impaired patients admitted to Henan Provincial People's Hospital as participants. The Chinese version of PNG-VS QoL was used to investigate and test the reliability and validity of the scale.Results:A total of 440 questionnaires were distributed, and after excluding invalid questionnaires that were illogical or had multiple choices, 435 valid questionnaires were collected, with an effective response rate of 98.86%. Exploratory factor analysis showed that the Chinese version of PNG-VS QoL extracted two common factors with a cumulative variance contribution rate of 73.651%. The Cronbach's α coefficient of the Chinese version of PNG-VS QoL was 0.934, and the Cronbach's α coefficients of the two dimensions were 0.934 and 0.925, respectively. The content validity index ( CVI) at the item level ranged from 0.800 to 1.000, and the CVI/ Ave at the scale level was 0.910. Confirmatory factor analysis showed that χ 2/ df was 1.533, TLI was 0.985, CFI was 0.992, and RMSEA was 0.043. Conclusions:The Chinese version of PNG-VS QoL has good psychometric properties and is suitable for evaluating the quality of life of visually impaired patients.

Background: Clinical chemistry tests are most widely used in clinical laboratories, and diverse measurement systems for these analyses are available in China. We evaluated the imprecision of clinical chemistry measurement systems based on internal QC (IQC) data. Methods: IQC data for 27 general chemistry analytes were collected in February each year from 2013 to 2022. Four performance specifications were used to calculate pass rates for CVs of IQC data in 2022. Boxplots were drawn to analyze trends of CVs, and differences in CVs among different groups were assessed using the Mann–Whitney U-test or Kruskal– Wallis test. Results: The number of participating laboratories increased significantly from 1,777 in 2013 to 5,425 in 2022. CVs significantly decreased for all 27 analytes, except creatine kinase and lipase. Triglycerides, total bilirubin, direct bilirubin, iron, and γ-glutamyl transferase achieved pass rates > 80% for all goals. Nine analytes with pass rates < 80% based on 1/3 allowable total error were further analyzed; the results indicated that closed systems exhibited lower CVs than open systems for all analytes, except total protein. For all nine analytes, differences were significant between tertiary hospitals and non-tertiary hospitals and between accredited and non-accredited laboratories. Conclusions The CVs of IQC data for clinical chemistry have seen a continuous overall improvement in China. However, there is ample room for imprecision improvement for several analytes, with stricter performance specifications.

Objective We aimed to investigate the hemostatic effect and mechanism of modified Sijunzi Decoction(MSJZT),consisting of tangshen,India bread,largehead atractylodes rhizome,liquorice root,milkvetch root,ass hide glue,and India madder root,on the zebrafish intestinal bleeding model through 5-hydroxytryptamine(5-HT)and its receptors(5-HT2aR,5-HT2bR).Methods Zebrafish at 4 days post fertilization were used as the research object.An intestinal bleeding model was established by induction with 6 μmol/L simvastatin for 24 hours.The zebrafish were divided into normal group,model group,MSJZT low-,mid-and high-concentration groups(55.6,167,500 mg/L),and after modeling,the corresponding concentration of MSJZT was administered.The samples were collected after 24 hours.Platelet count(PLT)and bleeding status were observed.The content of 5-HT and Caspase 3/7 activity were detected by colorimetry.The gene expressions of 5-HT2aR,5-HT2bR and serotonin transporter(SERT)were detected by real-time PCR.The protein expressions of protein kinase B(AKT),phosphorylated AKT(p-AKT),extracellular signal-regulated protein kinase(ERK),and phosphorylated ERK(p-ERK)were detected by Western blotting.Results The intestinal bleeding rate in the model group was 70.0%,and that in the MSJZT low-,mid-and high-concentration groups was 36.7%,40.0%,and 80.0%,respectively;the intestinal hemostatic effect was 54%,52%,and 7%,respectively.Compared with the model group,the PLT in the MSJZT low-and mid-concentration groups decreased;the content of 5-HT in all MSJZT groups increased,and the gene expressions of 5-HT2aR and 5-HT2bR were up-regulated.The gene expression of SERT was up-regulated in the low-and mid-concentration groups;the Caspase 3/7 activity in the mid-and high-concentration groups was reduced;the expressions of p-AKT and p-ERK proteins were up-regulated in the low-and mid-concentration groups(all P<0.05).Conclusion MSJZT can reduce the incidence and severity of intestinal bleeding in zebrafish intestinal bleeding models.The mechanism may be achieved by activating AKT and ERK signaling pathways through 5-HT and its receptors.

Objective:To evaluate the health benefits and intervention efficiency of different strategies of initiating antihypertensive therapy for the primary prevention of cardiovascular diseases in a community-based Chinese population from the Chinese electronic health records research in Yinzhou(CHERRY)study.Methods:A decision-analytic Markov model was used to simulate and compare different antihy-pertensive initiation strategies,including:Strategy 1,initiation of antihypertensive therapy for Chinese adults with systolic blood pressure(SBP)≥140 mmHg(2020 Chinese guideline on the primary preven-tion of cardiovascular diseases);Strategy 2,initiation of antihypertensive therapy for Chinese adults with SBP≥130 mmHg;Strategy 3,initiation of antihypertensive therapy for Chinese adults with SBP ≥140 mmHg,or with SBP between 130 and 140 mmHg and at high risk of cardiovascular diseases(2017 American College of Cardiology/American Heart Association guideline for the prevention,detection,evaluation,and management of high blood pressure in adults);Strategy 4,initiation of antihypertensive therapy for Chinese adults with SBP≥ 160 mmHg,or with SBP between 140 and 160 mmHg and at high risk of car-diovascular diseases(2019 United Kingdom National Institute for Health and Care Excellence guideline for the hypertension in adults:Diagnosis and management).The high 10-year cardiovascular risk was de-fined as the predicted risk over 10％based on the 2019 World Health Organization cardiovascular disease risk charts.Different strategies were simulated by the Markov model for ten years(cycles),with parame-ters mainly from the CHERRY study or published literature.After ten cycles of simulation,the numbers of quality-adjusted life years(QALY),cardiovascular events and all-cause deaths were calculated to evaluate the health benefits of each strategy,and the numbers needed to treat(NNT)for each cardiovas-cular event or all-cause death could be prevented were calculated to assess the intervention efficiency.One-way sensitivity analysis on the uncertainty of incidence rates of cardiovascular disease and probabilis-tic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted.Results:A to-tal of 213 987 Chinese adults aged 35-79 years without cardiovascular diseases were included.Com-pared with strategy 1,the number of cardiovascular events that could be prevented in strategy 2 increased by 666(95％UI:334-975),while the NNT per cardiovascular event prevented increased by 10(95％UI:7-20).In contrast to strategy 1,the number of cardiovascular events that could be prevented in strategy 3 increased by 388(95％UI:194-569),and the NNT per cardiovascular event prevented decreased by 6(95％UI:4-12),suggesting that strategy 3 had better health benefits and intervention efficiency.Compared to strategy 1,although the number of cardiovascular events that could be prevented decreased by 193(95％UI:98-281)in strategy 4,the NNT per cardiovascular event prevented decreased by 18(95％UI:13-37)with better efficiency.The results were consistent in the sensitivity analyses.Conclusion:When initiating antihypertensive therapy in an economically developed area of China,the strategy combined with cardiovascular risk assessment is more efficient than those purely based on the SBP threshold.The cardiovascular risk assessment strategy with different SBP thresholds is suggested to balance health benefits and intervention efficiency in diverse populations.
