Objective: To screen the frequency of CD36 antigen expression in platelet donor database in Shaanxi province and analyze the molecular genetic characteristics of samples with CD36 antigen deficiency and low expression. Methods: A total of 525 platelet donors samples were randomly collected during May 2023. CD36-FITC monoclonal antibody was used for immunofluorescence labeling, and flow cytometry was applied to detect the expression of CD36 antigen on platelets. For samples with CD36 antigen deficiency on platelets, the expression of CD36 on monocytes was further detected. Samples with CD36 antigen deficiency and low expression were sequenced and analyzed. Results: Among the 525 blood samples, 99.24% (521/525) showed positive expression of CD36 antigen. There were differences in the expression intensity of CD36 antigen, with low expression accounting for 3.43% (18/525) and CD36 antigen deficiency accounting for 0.76% (4/525), all of which were type Ⅱ deficiency. The exon mutation frequency of CD36 type Ⅱ deficiency and low expression samples was 31.82% (7/22), and the exon mutation types were 121-1_126delGCAAGTT, 329-330delAC, 1142T>G, 1204-1246dupl 43bp, 1221G>A, and 1228-1239delATTGTGCCTATT. All four cases of CD36 type Ⅱ deficiency had a 121-6 T>C mutation in intron 3. All CD36 low expression samples had a mutation of 282-10A>G, and 121-6T>C mutation rate was 61.1%(11/18). Conclusion: There were differences in the expression of CD36 antigen in the platelet donor database in Shaanxi province, which may be caused by multiple molecular genetic variations. The frequency of CD36 antigen deficiency in Shaanxi was lower than that of Han, Zhuang and Yao populations in southern China. This study provides references for solving the CD36 antibody mediated transfusion reaction and auxiliary treatment of diseases caused by CD36 antigen deficiency in the future. It also provides a basis for investigating the molecular mechanisms of CD36 deficiency and low expression.

Objective: To analyze the epidemiological characteristics of mumps in Shanxi Province from 2014 to 2023, so as to provide scientific evidence for targeted prevention strategies. Methods: Mumps case data in Shanxi Province were obtained from the China Information System for Disease Prevention and Control. Descriptive epidemiological analysis and age-period-cohort (APC) analysis were carried out on the reported incidence of mumps from 2014 to 2023. Results: A total of 44 360 mumps cases were reported in Shanxi Province from 2014 to 2023, with an average annual incidence rate of 11.78/100 000. The incidence rates were high during 2017-2019, which were 21.00/100 000, 16.76/100 000, and 19.51/100 000, respectively. Males had a higher incidence rate (13.50/100 000) than females (9.98/100 000). Children aged 5-9 years were the most affected group, accounting for 47.29% of total cases. In 2017 and 2019, incidence rates among the 5-15-year-old group were particularly high, reaching 155.08/100 000 and 131.78/100 000, respectively. The APC model age effect, period effect and cohort effect of the reported incidence rate in the high-incidence population aged 0-20 years all had statistical significance ( P <0.05). The age-relative risk ( RR ) decreased from 1.75 in the 0-year-old group to 0.33 in the 20-year-old group, and the birth cohort RR decreased from 2.58 in 1994 to 0.26 in 2023. The morbidity risk of the population aged 0-20 years showed a trend of first increasing and then decreasing over time, among which it was the highest in 2017 ( RR =1.23) and the lowest in 2023 ( RR =0.29). Conclusions Shanxi exhibits cyclical mumps epidemics, with school-aged children as the high-risk population. School health management work should be carried out, and the surveillance of mumps in high-risk areas and the routine vaccination of two doses of mumps-containing vaccines for eligible children should be strengthened.

Acute large-vessel occlusive ischemic stroke has high disability and mortality rates，causing a great burden to social economy and health care system. Mechanical thrombectomy has become the standard treatment method for this disease，but some patients still have poor prognosis after successful recanalization of blood vessels，and therefore，it is important to explore the factors that can be used to judge the poor prognosis of patients. Quantitative electroencephalography can quantify and objectively assess the changing process of brain function in patients，and RAPID perfusion parameters based on brain CTP can rapidly quantify the local blood perfusion of brain tissue. This combination of perfusion neuroimaging and electrophysiological activity can quantify the severity of ischemia associated with cerebral infarction and functional damage to neurons. This article reviews the application value of these two methods in the prognostic evaluation of stroke.

Objective To investigate the effect of tritiated water on the immune system of zebrafish and its potential molecular mechanism. Methods Zebrafish embryos (2.5 to 3 hours post-fertilization [hpf]) were exposed to 3.7 × 10⁴ Bq/mL tritiated water (tritiated water group), and those exposed to E3 culture medium were used as the control group. The mortality rate, hatching rate, deformity rate, heart rate, body length, yolk sac area, neutrophil count in the tail, immune-related gene expression, and immune-related protein expression of zebrafish in the two groups were determined. Then transcriptome technology was used to further analyze the possible mechanism of tritiated water affecting the immune system of zebrafish. Results Compared with the control group, zebrafish at 72 hpf in the tritiated water group had no significant changes in the mortality rate, hatching rate, deformity rate, body length, and yolk sac area((t = 0.9045, 0.5000, 1.0000, 0.7238, 0.0337, P = 0.4169, 0.6433, 0.3739, 0.4785, 0.9735), but had significantly increased heart rate(t = 4.575，P = 0.002). At 4 days post-fertilization (dpf), the neutrophil count in the tail of zebrafish in the tritiated water group was significantly increased(t = 2.563，P = 0.0196), the mRNA expression of TNF-α was significantly decreased(t = 2.891, P = 0.045), the protein expression of nuclear factor-kappa B (NF-κB) was significantly increased(t = 3.848, P = 0.018), and the protein expression of NLRP3 was significantly decreased(t = 14.98, P = 0.001). At 7 dpf, the neutrophil count in the tail and the protein expression levels of NF-κB, NLRP3, and interleukin-1β were significantly decreased(t = 3.772, 7.048, 15.620, 4.423, P = 0.014, 0.002, 0.0001, 0.012). Transcriptome sequencing revealed that differentially expressed genes were mainly enriched in the “neutrophil activation” and “platelet activation pathways” at 4 dpf and in the “neutrophil apoptosis”, “ferroptosis”, and “necroptosis” pathways at 7 dpf. Conclusion Tritiated water exposure induces a temporally dynamic immune response in zebrafish, potentially affecting immune homeostasis by regulating neutrophil activation and apoptosis, as well as the expression of NF-κB and NLRP3.

OBJECTIVE: To observe the clinical efficacy of acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux for gastroesophageal reflux cough (GERC). METHODS: A total of 120 GERC patients were randomly assigned to an observation group (60 cases, 1 case dropped out) and a control group (60 cases, 1 case was eliminated). The observation group received acupoint thread-embedding treatment at positive response points of governor vessel. If no such points were detected, the following acupoints were used: Dazhui (GV14), Fenghu (Extra), Shendao (GV11), Lingtai (GV10), and Zhiyang (GV9). Treatment was administered once every two weeks. The control group received oral rabeprazole enteric capsules at 20 mg twice daily. All the treatment was given for 6 weeks. Clinical outcomes were assessed using cough symptom score, reflux disease questionnaire (RDQ) score, and Leicester cough questionnaire (LCQ) score before and after treatment in the two groups. Clinical efficacy was also compared between the two groups. RESULTS: After treatment, both groups showed decreased cough symptom scores and the each item scores and total scores of RDQ (P<0.001), and increased LCQ scores (P<0.001) compare with those before treatment. The observation group exhibited lower cough symptom score and chest pain, reflux and total score of RDQ, and higher LCQ score compared to those in the control group (P<0.05). The total effective rate in the observation group was 94.9% (56/59), which was higher than 84.7% (50/59) in the control group (P<0.05). CONCLUSION Acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux could effectively alleviate cough and reflux symptoms in patients with GERC and improve their quality of life.

METHODS clinical application guidelines， expert consensus， drug instructions， drug registration data （including phase Ⅲ clinical trials）， meta- analysis/systematic review of databases such as PubMed and CNKI related to Vonoprazan fumarate tablets， Tegorasen tablets， and Keverprazan hydrochloride tablets already on the market in China were collected and organized. Based on the Quick Guidelines for Drug Evaluation and Selection in Chinese Medical Institutions （Second Edition）， a comprehensive evaluation of the three P-CAB drugs was conducted from five dimensions: pharmaceutical characteristics， efficacy， safety， economy， and the other property. RESULTS The five dimensions of the three P-CAB were ranked from high to low as follows： Vonoprazan fumarate tablets （81.8 points）， Tegorasen tablets （75.7 points）， and Keverprazan hydrochloride tablets （75.6 points）. Among them， Vonoprazan fumarate tablets scored the highest in 4 dimensions of pharmaceutical properties， efficacy， economy， and the other property； but the safety score was slightly low. CONCLUSIONS The three types of P-CAB are comprehensively strongly recommended and demonstrated good clinical efficacy. Vonoprazan fumarate tablets have more advantages in terms of pharmaceutical properties， efficacy， and economy.

Objective:To research the association between exposure to solid fuels for heating and its duration and the risk of respiratory diseases morbidity.Methods:Data from the China Kadoorie Biobank project sited in Pengzhou City, Sichuan Province. Cox proportional hazard regression model was used to analyze the association between exposure to solid fuels for heating and its duration and the risk of total respiratory diseases and the association between exposure to solid fuels for heating and the risk of chronic obstructive pulmonary disease (COPD) and pneumonia among respiratory diseases.Results:A total of 46 082 participants aged 30-79 years were enrolled, with 11 634 (25.25%) heating during the winter, of whom 8 885 (19.28%) used clean fuels and 2 749 (5.97%) used solid fuels, of whom 34 448 (74.75%) did not heat. After controlling for multiple confounding factors, Cox proportional hazard regression model was used, which revealed that compared with clean fuels, unheating could reduce the risk of total respiratory disease ( HR=0.81,95% CI:0.77-0.86), COPD ( HR=0.86,95% CI:0.78-0.95) and pneumonia ( HR=0.80,95% CI:0.74-0.86), respectively. Exposure to solid fuels increased the risk of total respiratory disease ( HR=1.10, 95% CI:1.01-1.20) and were not associated with COPD and pneumonia. Compared with no solid fuel exposure, the risk of total respiratory disease (1-19 years: HR=1.23, 95% CI:1.10-1.37; 20-39 years: HR=1.25, 95% CI:1.16-1.35; ≥40 years: HR=1.26, 95% CI:1.15-1.39) and COPD (1-19 years: HR=1.21, 95% CI:1.03-1.42; 20-39 years: HR=1.30, 95% CI:1.16-1.46; ≥40 years: HR=1.35, 95% CI:1.18-1.54) increased with the length of exposure of solid fuels (trend test P<0.001). Solid fuels exposure for 1-19 years and 20-39 years increased the risk of COPD by 23% ( HR=1.23,95% CI:1.02-1.49) and 16% ( HR=1.16, 95% CI:1.00-1.35). Conclusion:Heating solid fuels exposure increases the risk of total respiratory disease, COPD, and pneumonia.

Objective:To investigate the morbidity of cerebrovascular disease among residents ≥30 years in Pengzhou, Sichuan Province, and analyze the effect of physical activity level on the risk of morbidity of cerebrovascular disease.Methods:From 2004 to 2008, people from Pengzhou, Sichuan Province were randomly selected. All the local people aged 30-79 were asked to receive a questionnaire survey, physical examination, and long-term follow-up to determine the morbidity of cerebrovascular disease. The physical activity level and the morbidity of cerebrovascular disease were described, and Cox proportional hazard regression models were used to evaluate the association of domain-specific physical activity with the risk of morbidity of cerebrovascular disease.Results:In 55 126 participants, there were 5 290 new cases of cerebrovascular disease, with a cumulative incidence of 9.60%. After the adjustment for multiple confounding factors, multivariate Cox proportional hazard regression analysis showed that increased levels of occupational, transportation, and total physical activity reduced the risk of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). The highest group of occupational physical activity level had the lowest risk of cerebrovascular disease, with a hazard ratio ( HR) value of 0.81 (95% CI: 0.75-0.88), the highest group of transportation physical activity level had the lowest risk of cerebrovascular disease, with an HR value of 0.84 (95% CI: 0.78-0.91), the highest group of total physical activity level had the lowest risk of cerebrovascular disease, with an HR value of 0.87 (95% CI: 0.80-0.94), compared with the lowest group of corresponding physical activity. No association was found between the household/leisure-time physical activity level and the risk of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). Conclusions:In project areas of Pengzhou, Sichuan Province, increased physical activity has been associated with reduced morbidity of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). Increased levels of physical activity in adults are encouraged for health benefits.
