Objective:To explore the therapeutic efficacy and prognostic factors of induction therapy for secondary central nervous system lymphoma(SCNSL).Methods:Clinical data of patients diagnosed with SCNSL from 2010 to 2021 at Guangdong Provincial People's Hospital were retrospectively collected.A retrospective cohort study was performed on all and grouped patients to analyze the efficacy and survival.Multivariate logistic regression analysis was used to explore the adverse prognostic factors.Results:Thirty-seven diffuse large B-cell lymphoma patients with secondary central involvement were included in the research.Their 2-year overall survival(OS)rate was 46.01％and median survival time was 18.1 months.The 2-year OS rates of HD-MTX group and TMZ group were 34.3％and 61％,median survival time were 8.7 and 38.3 months,and median progression-free survival time were 8.1 and 47 months,respectively.Multivariate logistic regression analysis showed that age,sex,IPI,Ann Arbor stage were correlated with patient survival time.The median survival time of patients with CD79B,KMT2D,CXCR4.ERBB2,TBL1XR1,BTG2,MYC,MYD88,and PIM1 mutations was 8.2 months,which was lower than the overall level.Conclusion:HD-MTX combined with TMZ as the first-line strategy may improve patient prognosis,and early application of gene sequencing is beneficial for evaluating prognosis.

Objective:To evaluate the efficacy and safety of Xiao′er Huangjin Zhike Granules in the treatment of cough caused by acute bronchitis in children, which is defined in TCM terms as a syndrome of phlegm-heat obstructing the lung.Methods:This was a block-randomized, double-blind, placebo-controlled, multicenter clinical trial.From January 2022 to September 2023, 359 children aged 3 to 7 years old diagnosed as acute bronchitis (lung-obstructing phlegm-heat syndrome) were enrolled from 21 participating hospitals and randomly assigned to the experimental group and placebo group in a 3︰1 ratio, and respectively treated with Xiao′er Huangjin Zhike Granules and its matching placebo.Cough resolution/general resolution rate after 7 days of treatment was used as the primary efficacy outcome for both groups.Results:(1)On the seventh day of treatment, the rate of cough disappearance/basically disappearance in the experimental group and placebo group were 73.95% and 57.61% retrospectively, which had statistically significance ( P=0.001).(2)After 7 days of treatment, the median duration of cough disappearance/basic disappearance were 5 days and 6 days in the two groups , with a statistically significant difference ( P=0.006).The area under the curve of cough symptom severity time was 7.20 ± 3.79 in the experimental group and 8.20±4.42 in the placebo group.The difference between the two groups was statistically significant ( P=0.039).(3) After 7 days of treatment, the difference between TCM syndrome score and baseline was -16.0 (-20.0, -15.0) points in the experimental group and -15.0 (-18.0, -12.0) points in the placebo group, with significant difference between the two groups ( P=0.004).In the experimental group, the clinical control rate, the markedly effective rate, the effective rate and the ineffective rate were 49.04%, 28.35%, 16.48% and 6.13% severally; and in the placebo group, the clinical control rate, the markedly effective rate, the effective rate and the ineffective rate were 38.04%, 26.09%, 29.35%, and 6.52% separately, which had statistically significant ( P=0.014).(4) There was no significant difference in the incidence of adverse events or adverse reactions during the trial between both groups.Moreover, while adverse reactions in the form of vomiting and diarrhea were occasionally reported, no serious drug-related adverse event or adverse reaction was reported.(5)The tested drug provided good treatment compliance, showing no statistically significant difference from the placebo in terms of compliance rate. Conclusions:Based on the above findings, it can be concluded that Xiao′er Huangjin Zhike Granules provides good safety, efficacy, and treatment compliance in the treatment of cough caused by acute bronchitis, and lung-obstructing phlegm-heat syndrome, in children.

Objective To explore the effect and prognostic factors of intravenous thrombolysis combined with Trevo stent mechanical thrombectomy in the treatment of ischemic stroke.Methods A total of 120 patients with ischemic stroke diagnosed and treated in our hospital from January 2020 to December 2022 were selected as research objects and divided into two groups according to random number table method,with 60 cases in each group.Both groups were given basic treatment,the control group was given intravenous thrombolytic therapy,and the observation group was given intravenous thrombolytic therapy combined with mechanical thrombectomy with Trevo stent.The clinical efficacy of the two groups was observed,and the patients were divided into a good prognosis group(46 cases)and a poor prognosis group(74 cases)according to the prognosis.Clinical data such as gender,age,BMI,combined hypertension,combined diabetes,smoking,treatment methods,complete vascular recirculation rate,preoperative NIHSS score and postoperative NIHSS score of the two groups were collected.The independent prognostic factors were analyzed by univariate and multivariate binary Logistic regression.Results The total effective rate of the study group was significantly higher 88.33％(53/60)than that of the control group 73.33％(44/60),and the difference was statistically significant(P＜0.05).Univariate analysis showed that there were no statistically significant differences in gender,BMI,diabetes mellitus,and preoperative NIHSS score between the two groups(P＞0.05),while there were statistically significant differences in age,hypertension,smoking,treatment style,complete vascular revasculosity,and postoperative NIHSS score between the two groups(P＜0.05).Logistic regression analysis showed that age,treatment style and complete vascular revasculopathy rate were independent factors affecting the prognosis of ischemic stroke patients(P＜0.05).Conclusion Intravenous thrombolysis combined with mechanical thrombectomy with Trevo stent can improve the clinical efficacy and prognostic quality of ischemic stroke patients in the time window of intravenous thrombolysis.In addition,the prognosis of patients with ischemic stroke is also closely related to the age of patients and the rate of complete vascular recirculation after surgery.

Objective: To investigate the epidemiological characteristics of hand, foot, and-mouth disease (HFMD) among children under 6 years in Wuxing District, Huzhou City from 2013 to 2021, so as to provide insights into HFMC control among children. Methods : The surveillance on HFMD and enterovirus 71 (EV71) vaccination among children under 6 years in Wuxing District, Huzhou City from 2013 to 2021 were captured from China Disease Prevention and Control Information System, and the temporal, human and spatial distributions of HFMD cases and pathogenic detection results were descriptively analyzed. Results : A total of 14 272 HFMD cases under 6 years were reported in Wuxing District from 2013 to 2021, with an average annual incidence rate of 465.75/104. There were 8 313 male children with HFMD (522.39/104 incidence) and 5 959 female children with HFMD (404.55/104 incidence), and higher incidence of HFMD was seen among male children than among female children (χ2=239.228, P<0.001). Most HFMD cases were found among children at ages of 1 to 3 years (10 006 cases, 70.11%), and the incidence of HFMD peaked during the period between May and July and between October and December each year. High incidence of HFMD was seen in Zhili Township (741.50/104), Yangjiabu Street (546.99/104) and Balidian Township (438.68/104). There were 717 laboratory-confirmed HFMD cases (5.02%), including 106 EV71-positive cases (14.78%) and 177 CoxA16-positive cases (24.69%). A total of 56 288 doses of EV71 vaccines were administered in Wuxing District from 2017 to 2021, with an annual average full-dose vaccination rate of 14.87%. The detection of EV71 infection was significantly lower after EV71 vaccination than before vaccination (4.49% vs. 24.93%; χ2=62.932, P<0.001). Conclusions The incidence of HFMD peaks in summer and winter among children under 6 years in Wuxing District, which predominantly occurs among children at ages of 1 to 3 years. The incidence of HFMD is high in Zhili Township, Yangjiabu Street and Balidian Township, and the number of EV71-positive cases significantly reduces after EV71 vaccination than before vaccination.

Obesity is a disease with a major negative impact on human health. However, people with obesity may not perceive their weight to be a significant problem and less than half of patients with obesity are advised by their physicians to lose weight. The purpose of this review is to highlight the importance of managing overweight and obesity by discussing the adverse consequences and impact of obesity. In summary, obesity is strongly related to >50 medical conditions, with many of them having evidence from Mendelian randomisation studies to support causality. The clinical, social and economic burdens of obesity are considerable, with these burdens potentially impacting future generations as well. This review highlights the adverse health and economic consequences of obesity and the importance of an urgent and concerted effort towards the prevention and management of obesity to reduce the burden of obesity.

Objective: To analyze the epidemiological characteristics of typhus in China from 1950 to 2021, and discuss the challenges in typhus prevention and control in China and suggest future prevention and control strategies. Methods: Based on the reported data of typhus from 1950 to 2021 in China from the Infectious Disease History Database of China Public Health Science Data Center and the National Notifiable Infectious Disease Reporting Information System of Chinese Center for Disease Control and Prevention, we conducted a descriptive statistical analysis. Mann-Kendall test and circular distribution method were used to analyze the incidence, mortality and case fatality of typhus to reveal the temporal, spatial and population distributions and diagnosis of typhus in China. Results: From 1950 to 2021, a total of 452 965 typhus cases and 7 339 typhus deaths were reported in China, with the cases numbers exceeding 10 000 in 14 years of the 1950s, 1960s and 1980s, respectively. Since 1990s, the reported cases and incidence rate of typhus have decreased dramatically and the most cases were sporadic. However, the reported typhus cases in Anhui, Hubei, Hunan Provinces showed significant uptrends. Although typhus could occur all the year round, but the seasonality was observed with the incidence mainly in summer and autumn. For different provinces from the north to the south, the peaks of typhus' monthly incidence tended to shift to earlier dates. The male to female ratio of the cases was 1.01∶1 (18 529∶18 366). However, more cases occurred in women in recent years. The cases aged ≤9 years accounted for the highest proportion (18.9%), but the number of cases aged ≥50 years showed an upward trend. Most cases were farmers with the proportion increasing year by year. Moreover, the cases in students and scattered-living children also accounted for relatively higher proportions. The median of the interval between onset and diagnosis of typhus was 6 days. Most cases were clinically diagnosed, while the proportion of laboratory-confirmed cases was low and most laboratory cases were confirmed by Well-Felix reaction. Conclusions: Although the incidence and mortality of typhus in China has decreased significantly, the risk for local typhus outbreaks still exists. The prevention and control of typhus still face many challenges. It is indispensable to strengthen the pathogen detection and surveillance for typhus in China.

The study aimed to explore the effects of inoculation of Rhizophagus intraradices on the biomass, effective component content, and endogenous hormone content of Salvia miltiorrhiza through pot experiments. The number of leaves, plant height, dry weight of aboveground and underground parts, branch number, root number, root length, root diameter, and other biomass were mea-sured by weighing and counting methods. The content of salvianolic acid B, caffeic acid, rosmarinic acid, tanshinone Ⅰ, tanshinone Ⅱ_A, cryptotanshinone, and other effective components was determined by ultra-high performance liquid chromatography. The content of ABA and GA_3 was determined by triple quadrupole mass spectrometry. The correlations between biomass and effective components and between effective components and plant hormones ABA and GA_3 were analyzed. The results showed that R. intraradices significan-tly increased the aboveground dry weight, leaf number, and root number of S. miltiorrhiza by 0.24-0.65 times, respectively. The content of salvianolic acid B and rosmarinic acid in the aboveground part and the content of salvianolic acid B, caffeic acid, rosmarinic acid, tanshinone Ⅰ, and tanshinone Ⅱ_A in the underground part were significantly increased by 0.44-1.78 times, respectively. R. intraradices infection significantly increased the GA_3/ABA values of aboveground and underground parts by 3.82 and 76.47 times, respectively. The correlation analysis showed that caffeic acid, the effective component of the aboveground part, was significantly positively correlated with plant height, tanshinone Ⅱ_A, the effective component of the underground part, was significantly positively correlated with biomass root number, cryptotanshinone, and dry weight, while rosmarinic acid was significantly negatively correlated with dry weight. There were significant positive correlations between cryptotanshinone and ABA, tanshinone Ⅱ_A and ABA and GA_3, and caffeic acid and GA_3. In conclusion, R. intraradices can promote the accumulation of biomass and secondary metabolites of S. miltiorrhiza and regulate the balance between plant hormones ABA and GA_3, thereby promoting the growth of S. miltiorrhiza.
