Objective Analyze the temporal trend of ischemic stroke(IS)mortality among the residents of Tengzhou City of Shandong Province during the period of hypertension control from 2013 to 2021.Methods On January 1,2013,Tengzhou City,Shandong Province,began its hypertension control program.The IS mortality rate was calculated using the mortality data from January 1,2013 to December 31,2021,and analyzed for its time trend among residents with different characteristics.The registered population was derived from the Public Security Bureau of Tengzhou City,Shandong Province,and the age and sex standardized mortality rate was calculated using the data of China's 7th population census in 2020.The Chi-square test was used to compare the differences in mortality rate,and Cochran-Armitage trend test was used to compare the time trend and age trend of mortality rate.Results The overall crude and standardized mortality rates of IS in Tengzhou showed a temporal trend from 2013 to 2021(Z values were 12.647,7.305,respectively;all P＜0.001),and decreased by 23.77％and 30.99％(Z values were-7.393,-9.975,respectively;all P＜0.001)respectively in 2021 compared with 2019.The crude mortality rate of IS in male increased by 13.27％in 2019 compared with 2017,while the crude and standardized mortality rate in female decreased by 16.39％and 19.49％in 2018 compared with 2017,respectively,with statistical significance(x2 values were 7.160,9.789,and 15.109,respectively;all P＜0.05).Except the crude mortality rates in 2013 and 2015,the crude mortality rates and standardized mortality rates for males in other years were all higher than those for females,with statistically significant differences(x2 values:25.816-124.040,all P＜0.001).The crude mortality rate for IS increased with age in all years(Z values:42.604-61.025,all P＜0.001).The proportion of IS deaths among those aged≥65 was 85.85％.The overall crude mortality rates of the age group of male 45-54 years old showed a temporal trend from 2013 to 2021(Z=3.035,P＜0.01),while females in the same age group did not show a temporal trend(P＞0.05).The IS mortality rate in urban areas decreased from 62.61 per 100 000 in 2013 to 54.00 per 100 000 in 2021(Z=-2.097,P＜0.05).The rural areas increased by 213.15％in 2019 compared with 2013 and decreased by 22.75％in 2021 compared with 2019(Z values were 19.074,-6.390,respectively;all P＜0.001).Conclusions The IS mortality rate in Tengzhou City showed a decreasing trend in urban areas from 2013 to 2021,and a decreasing trend in rural areas after 2019.Compared to females,there is a trend of younger mortality among males in the age range of 45-54.Males and rural IS patients should be given special attention.

Patients with lung cancer at the same stage may have markedly different overall outcome and a lack of specific biomarker to predict lung cancer outcome. Heat-shock protein 90 β (HSP90β) is overexpressed in various tumor cells. In this study, the ELISA results of HSP90β combined with CEA, CA125, and CYFRA21-1 were used to construct a recursive partitioning decision tree model to establish a four-protein diagnostic model and predict the survival of patients with lung cancer. Survival analysis showed that the recursive partitioning decision tree could distinguish the prognosis between high- and low-risk groups. Results suggested that the joint detection of HSP90β, CEA, CA125, and CYFRA21-1 in the peripheral blood of patients with lung cancer is plausible for early diagnosis and prognosis prediction of lung cancer.

Abstract In order to achieve the goal of reducing the smoking rate among Chinese adults at ages of 15 years and above to below 20% by 2030, smoking cessation services require to be reinforced. The current Chinese smoking cessation service system includes short-term smoking cessation interventions and smoking cessation hotlines at the population level, and smoking cessation clinics at the individual level; however, these smoking cessation services suffer from problems of low awareness, low accessibility and low utilization rate. Based on the publications pertaining to smoking cessation services and released policy documents in China until June 2022, this review analyzes the current status, problems and causes of smoking cessation services, and proposes suggestions for improving the smoking cessation service system construction in China.

Macrolide and corticosteroid resistance has been reported in patients with Mycoplasma pneumoniae (MP) pneumonia (MPP). MP clearance is difficult to achieve through antibiotic treatment in sensitive patients with severe MPP (SMPP). SMPP in children might progress to airway remodeling and even bronchiolitis/bronchitis obliterans. Therefore, identifying serum biomarkers that indicate MPP progression and exploring new targeted drugs for SMPP treatment require urgency. In this study, serum samples were collected from patients with general MPP (GMPP) and SMPP to conduct proteomics profiling. The Fc fragment of the IgG-binding protein (FCGBP) was identified as the most promising indicator of SMPP. Biological enrichment analysis indicated uncontrolled inflammation in SMPP. ELISA results proved that the FCGBP level in patients with SMPP was substantially higher than that in patients with GMPP. Furthermore, the FCGBP levels showed a decreasing trend in patients with GMPP but the opposite trend in patients with SMPP during disease progression. Connectivity map analyses identified 25 possible targeted drugs for SMPP treatment. Among them, a mechanistic target of rapamycin kinase (mTOR) inhibitor, which is a macrolide compound and a cell proliferation inhibitor, was the most promising candidate for targeting SMPP. To our knowledge, this study was the first proteomics-based characterization of patients with SMPP and GMPP.

Objective : To investigate the predictive value of serum homocysteine(HCY) level on the risk of miscarriage in polycystic ovary syndrome(PCOS) patients undergoing frozen-thawed embryo transfer(FET). Methods: 536 PCOS patients and 550 non-PCOS patients with fallopian tube factors(control group) retrospectively were analyzed.The basic characteristics and pregnancy outcomes were compared between the two groups.Also, the basic characteristics between the miscarriage group and the live birth group in PCOS patients were compared.The predictive value of Hcy on the miscarriage of PCOS patients after FET treatment was analyzed. Results: Compared with the control group, body mass index(BMI),testosterone(T),Hcy, fasting insulin(FINS),homeostasis model assessment of insulin resistance(HOMA-IR),total cholesterol(TC),number of retrieved oocytes and miscarriage rate increased in PCOS group, while high density lipoprotein-cholesterol(HDL-C),high-quality embryo rate and live birth rate decreased, and the differences were statistically significant(P<0.05).Among PCOS patients, Hcy, FINS and HOMA-IR increased in the miscarriage group compared with live birth group, and the differences were statistically significant(P<0.05).Hcy, FINS and HOMA-IR were independent risk factors for miscarriage in PCOS patients, and the predictive value of Hcy for miscarriage in PCOS patients was greater than FINS and HOMA-IR,and the area under ROC curve(AUC) was 0.829(95%CI=0.755-0.902,P<0.001),the cut-off value was 15.975 μmol/L with a 79.0% sensitivity and a 87.4% specificity, which indicated high predictive value for miscarriage in patients with PCOS. Conclusion Serum Hcy level significantly increased in PCOS patients, which has an important predictive value for miscarriage after FET treatment.

Biomarkers for hepatocellular carcinoma (HCC) following curative resection are not currently sufficient for prognostic indication of overall survival (OS) and disease-free survival (DFS). The aim of this study was to investigate the prognostic performance of osteopontin (OPN), matrix metalloproteinase 7 (MMP7), and pregnancy specific glycoprotein 9 (PSG9) in patients with HCC. A total of 179 prospective patients with HCC provided plasma before hepatectomy. Plasma OPN, MMP7, and PSG9 levels were determined by enzyme-linked immunosorbent assay. Correlations between plasma levels, clinical parameters, and outcomes (OS and DFS) were overall analyzed. High OPN ( ⩾ 149.97 ng/mL), MMP7 ( ⩾ 2.28 ng/mL), and PSG9 ( ⩾ 45.59 ng/mL) were prognostic indicators of reduced OS (P < 0.001, P < 0.001, and P = 0.007, respectively). Plasma PSG9 protein level was an independent factor in predicting OS (P = 0.008) and DFS (P = 0.038). Plasma OPN + MMP7 + PSG9 elevation in combination was a prognostic factor for OS (P < 0.001). OPN was demonstrated to be a risk factorassociated OS in stage I patients with HCC and patients with low α-fetoprotein levels ( < 20 ng/mL). These findings suggested that OPN, MMP7, PSG9 and their combined panels may be useful for aiding in tumor recurrence and mortality risk prediction of patients with HCC, particularly in the early stage of HCC carcinogenesis.

T cells and T cell receptors (TCRs) play pivotal roles in adaptive immune responses against tumors. The development of next-generation sequencing technologies has enabled the analysis of the TCRβ repertoire usage. Given the scarce investigations on the TCR repertoire in lung cancer tissues, in this study, we analyzed TCRβ repertoires in lung cancer tissues and the matched distant non-tumor lung tissues (normal lung tissues) from 15 lung cancer patients. Based on our results, the general distribution of T cell clones was similar between cancer tissues and normal lung tissues; however, the proportion of highly expanded clones was significantly higher in normal lung tissues than in cancer tissues (0.021% ± 0.002% vs. 0.016% ± 0.001%, P = 0.0054, Wilcoxon signed rank test). In addition, a significantly higher TCR diversity was observed in cancer tissues than in normal lung tissues (431.37 ± 305.96 vs. 166.20 ± 101.58, P = 0.0075, Mann-Whitney U test). Moreover, younger patients had a significantly higher TCR diversity than older patients (640.7 ± 295.3 vs. 291.8 ± 233.6, P = 0.036, Mann-Whitney U test), and the higher TCR diversity in tumors was significantly associated with worse cancer outcomes. Thus, we provided a comprehensive comparison of the TCR repertoires between cancer tissues and matched normal lung tissues and demonstrated the presence of distinct T cell immune microenvironments in lung cancer patients.

Objective:To explore the association between sibling violence experience and emotional and behavioral problems.Methods:A Multistage stratified cluster sampling was used in Hunan province, 1735 participants from multiple-child family were recruited to survey the prevalence of sibling violence and the occurrence of emotional and behavioral problems with the Strength and Difficulties Questionnaires (SDQ).Results:According to SDQ total score, the rate of abnormal emotion and behavior in children and adolescents involved in sibling violence was higher than that in students who were not experienced sibling violence [45.6％ (236/518) vs.26.8％ (326/1217) ], the rate in bully-victim was higher than that in pure-victim and pure-bully [52.8％ (132/250) vs.37.9％ (74/195) vs.41.1％ (30/73) ].The rates in children and adolescents who were bullied and perpetrated more than 4 sub-types of sibling violence were 63.4％ (53/93) and 76.9％ (60/78).Conclusion:There is an association between sibling violence experience and emotional and behavioral problems among children and adolescents in rural areas.

Objective: To explore the clinical features, the serotype distribution and drug resistance of the isolates in patient with invasive pneumococcal disease (IPD). Methods: By retrieving the laboratory information system in 18 children′s hospitals from 2012 to 2017, the children with IPD were enrolled. Streptococcus pneumoniae (Spn) must be isolated from the sterile sites (blood, cerebrospinal fluid, hydrothorax and joint effusion etc.). The clinical characteristics, serotype, drug resistance, treatment and prognosis were reviewed and analyzed. According to the telephone follow up results, the patients were divided into death group and recovered group. The index as an independent risk factor of mortality was demonstrated by multivariate logistic regression analysis. Results: There were 1 138 children with IPD, including 684 male and 454 female. The proportion of male to female was 1.5∶1. The age ranged from one day to 16 years. The median age was 1 year 3 month. The majority was under 5 years of age (89.3%, n= 1 016), especially under 2 years of age (61.9%, n=704). In all cases, 88.2% (n=1 004) were community acquired infection. The infections included meningitis (n=446, 39.2%), pneumonia with bacteremia (n=339, 29.8%), and bacteremia without focus (n=232, 20.4%). Underlying diseases were found in 242 cases (21.3%). Co-infections were determined in 62 cases (5.4%) with mycoplasma, 27 cases (2.4%) with adenovirus and 34 cases with influenza virus (3.0%). The penicillin insensitivity (PNSP) rates in meningitis and non-meningitis isolates were 69.5% (276/397) and 35.9% (221/615), respectively. There were 81 strains serotyped, in which 93.8% (76/81) were covered by 13-valent protein-polysaccharide conjugate vaccine (PCV13). In the 965 patients who were followed up by phone call, 156 cases (16.2%) were confirmed dead. The independent risk factors for the death were under 2 years of age (OR=2.143, 95%CI 1.284-3.577, P=0.004), meningitis (OR=3.066, 95%CI 1.852-5.074, P<0.01), underlying disease (OR=4.801, 95%CI 2.953-7.804, P<0.01), septic shock(OR=3.542, 95%CI 1.829-6.859, P<0.01), disseminated intravascular coagulation (DIC) (OR=4.150, 95%CI 1.468-11.733, P=0.007), multiple organ failure (OR=12.693, 95%CI 6.623-24.325, P<0.01) and complications of central nervous system (OR=1.975, 95%CI 1.144-3.410, P=0.015). Conclusions Most children with IPD were under 5 years of age, having underlying diseases and acquired the infection in community. The independent risk factors for death were under two years old, meningitis, underlying diseases and multiple organ failure. The problem of drug resistance was severe. The universal immunization of PCV13 would be effective to prevent IPD in Chinese children.

Aim To investigate the effect of isocorydine on arrhythmia in rats induced by myocardial ischemia/reperfusion injury. Methods SD rats were randomly divided into 6 groups: sham group, myocardial ische-mia/reperfusion group, verapamil group and isoc-orydine group of 2. 5 , 5 , 10 mg · kg-1 , each group having 16 rats. Left anterior descending ( LAD ) was tied up to establish the injury model of myocardial is-chemia. ECG was recorded for analysis. The ischemic and infarction area was measured and indexes of SOD, MDA, GSH-Px in the myocardial were determined. Re-sults Isocorydine could significantly reduce the inci-dence of arrhythmia induced by ischemic/reperfusion, including VT, VF;and reduce ischemic and infarction area. Further study demonstrated that isocorydine could increase myocardial SOD and GSH-Px, but de-crease myocardial MDA. Conclusion Isocorydine has a protective effect on the myocardial ischemia/reperfu-sion injury, which might be related to its anti-oxidative function.
