Objective: To investigate the epidemilogical characteristics of pulmonary tuberculosis in Huzhou City, Zhejiang Province from 2014 to 2023, so as to provide the basis for formulating prevention and control measures for the construction of "TB-free city". Methods: The data of pulmonary tuberculosis cases in Huzhou City from 2014 to 2023 was collected through the Infectious Disease Reporting Management System of Chinese Disease Prevention and Control Information System. The onset time, region, and population distribution characteristics of the cases were described. Results: A total of 11 598 cases of pulmonary tuberculosis were reported in Huzhou City from 2014 to 2023, with an average annual incidence of 37.42/105. The reported incidence decreased from 47.50/105 in 2014 to 28.36/105 in 2023 (P<0.05), with an annual decline rate of 5.57%. There were 6 304 etiological positive cases, accounting for 54.35%. The peak season for pulmonary tuberculosis cases was from March to September, with the highest seasonal ratio of 112.48% in May. The average annual reported incidence rates in Anji County and Changxing County were relatively high (46.14/105 and 41.15/105). The reported incidence rate of pulmonary tuberculosis in Huzhou City increased with age (P<0.05), peaking at 97.36/105 in the group aged 75 to <80 years. There were 7 991 male pulmonary tuberculosis cases and 3 607 female cases, with a male-to-female ratio of 2.22∶1. The average annual incidence rates of pulmonary tuberculosis was higher in males than in females (50.39/105 vs. 23.87/105). Farmers were the primary occupation affected, with 6 350 cases accounting for 54.75%. Conclusions The reported incidence rate of pulmonary tuberculosis in Huzhou City decreased from 2014 to 2023, with a high incidence in spring and summer. The incidence rates in Anji County and Changxing County were higher than Huzhou City's average. Male, elderly residents and farmers were the key populations for pulmonary tuberculosis prevention and control.

GI (GIGANTEA) is one of the output key genes for circadian clock in the plant. The JrGI gene was cloned and its expression in different tissues was analyzed to facilitate the functional research of JrGI. RT-PCR (reverse transcription-polymerase chain reaction) was used to clone JrGI gene in present study. This gene was then analyzed by bioinformatics, subcellular localization and gene expression. The coding sequence (CDS) full length of JrGI gene was 3 516 bp, encoding 1 171 amino acids with a molecular mass of 128.60 kDa and a theoretical isoelectric point of 6.13. It was a hydrophilic protein. Phylogenetic analysis showed that JrGI of 'Xinxin 2' was highly homologous to GI of Populus euphratica. The result of subcellular localization showed that JrGI protein was located in nucleus. The JrGI, JrCO and JrFT genes in female flower buds undifferentiated and early differentiated of 'Xinxin 2' were analyzed by RT-qPCR (real-time quantitative PCR). The results showed that the expression of JrGI, JrCO and JrFT genes were the highest on morphological differentiation, implying the temporal and special regulation of JrGI in the differential process of female flower buds of'Xinxin 2'. In addition, RT-qPCR analysis showed that JrGI gene was expressed in all tissues examined, whereas the expression level in leaves was the highest. It is suggested that JrGI gene plays a key role in the development of walnut leaves.

Background: and Purpose The optimal management of patients with acute basilar artery occlusion (BAO) is uncertain. We aimed to evaluate the safety and efficacy of endovascular thrombectomy (EVT) compared to medical management (MM) for acute BAO through a meta-analysis of randomized controlled trials (RCTs). Methods: We performed a systematic review and meta-analysis of RCTs of patients with acute BAO. We analyzed the pooled effect of EVT compared to MM on the primary outcome (modified Rankin Scale [mRS] of 0–3 at 3 months), secondary outcome (mRS 0–2 at 3 months), symptomatic intracranial hemorrhage (sICH), and 3-month mortality rates. For each study, effect sizes were computed as odds ratios (ORs) with random effects and Mantel-Haenszel weighting. Results: Four RCTs met inclusion criteria including 988 patients. There were higher odds of mRS of 0-3 at 90 days in the EVT versus MM group (45.1% vs. 29.1%, OR 1.99, 95% confidence interval [CI] 1.04–3.80; P=0.04). Patients receiving EVT had a higher sICH compared to MM (5.4% vs. 0.8%, OR 7.89, 95% CI 4.10–15.19; P<0.01). Mortality was lower in the EVT group (35.5% vs. 45.1%, OR 0.64, 95% CI 0.42–0.99; P=0.05). In an analysis of two trials with BAO patients and National Institutes of Health Stroke Scale (NIHSS) <10, there was no difference in 90-day outcomes between EVT versus MM. Conclusion In this systematic review and meta-analysis, EVT was associated with favorable outcome and decreased mortality in patients with BAO up to 24 hours from stroke symptoms compared to MM. The treatment effect in BAO patients with NIHSS <10 was less certain. Further studies are of interest to evaluate the efficacy of EVT in basilar occlusion patients with milder symptoms.

Objective:To evaluate the safety and feasibility of endovascular recanalization for non-acute internal carotid artery occlusion (NA-ICAO), and to propose a new angiographic classification.Methods:From April 2015 to October 2019, 95 consecutive patients with symptomatic NA-ICAO who received endovascular recanalization were retrospectively analyzed in Beijing Tiantan Hospital, Capital Medical University. All the patients were divided into four groups according to DSA: type Ⅰ, petrous segments were distally reconstituted by collateral vessels; type Ⅱ, cavernous segments were distally reconstituted by collateral vessels; type Ⅲ, ophthalmic segments were distally reconstituted by collateral vessels; type Ⅳ, communicating segments were distally reconstituted by collateral vessels. Study data including clinical characteristics, surgical details, lesion classification, recanalization rate and perioperative complications. For the counting data, the χ 2 test was used to compare between groups. For the quantitative data, the ANOVA was used for the normal distribution data, otherwise the Kruskal-Wallis H test was used. The primary safety outcome was any stroke or death within 30 days. Results:Among the 95 patients, 67 (70.53%) had successful recanalization. The recanalization rates of type Ⅰ－Ⅳ were 92.31% (36/39), 81.82% (18/22), 47.83% (11/23) and 18.18% (2/11) respectively (χ2=29.557, P<0.001). And the complication rates of the four types were 5.13% (2/39), 13.64% (3/22), 21.74% (5/23) and 9.10% (1/11) respectively. The incidence of perioperative ischemic stroke was 2.11% (2/95). No other serious stroke and death occurred. Conclusions:Endovascular recanalization may be feasible and safe for carefully selected patients with NA-ICAO and therefore represents an alternative treatment. The patients with type Ⅰ and Ⅱ lesions had higher recanalization rates, while the patients with type Ⅳ lesions had significantly lower recalculation rate. The new angiographic classification is conducive to the selection of suitable patients and difficulty in grading.

Objective:To compare the safety and therapeutic effect of bridging therapy versus direct endovascular treatment in patients with acute ischemic stroke(AIS)aged 80 years and over, who received the therapy within 4.5 h of onset.Methods:A total of 89 AIS patients aged 80 years and over receiving the endovascular therapy at our hospital from January 2016 to June 2019 were studied with versus without intravenous thrombolysis before endovascular therapy(the former as bridging therapy group, n=49; the latter as the direct endovascular treatment group, n=40). Baseline information including gender, the modified Rankin scale(mRS)score, medical history, smoking history, preoperative national institute of health stroke scale(NIHSS)score were collected.Clinical data related to the operation including the times from onset to hospital, door-to-puncture and door-to-recanalization, complications(symptomatic cerebral hemorrhage, mortality)and mRS at 90 d after treatment were compared between the two groups.Multiple logistic regression analysis was used to determine whether or not bridging therapy with intravenous thrombolysis was a prognostic factor.Results:There was no significant difference in baseline information between the two groups( P>0.05). The times from onset to hospital, door-to-puncture, door-to-recanalization had no significant difference between the two groups( P>0.05). There was no significant difference in the incidence of symptomatic cerebral hemorrhage and mortality within 90 d between the two groups(26.5% or 13 cases vs. 17.5% or 7 cases, 14.3% or 7 cases vs.7.5% or 3 cases, χ2=1.031 and 1.017, P=0.310 and 0.313). With different clinical outcomes as dependent variables, after adjusting factors such as gender, admission NIHSS and medical history, Logistic regression analysis showed that the bridging therapy with intravenous thrombolysis was not a prognostic factor( OR=0.795, 95% CI: 0.280~2.258, P=0.666). Conclusions:The bridging therapy is as safe and effective as the direct intravascular therapy for AIS patients aged 80 and over within 4.5 hours of onset.The intravenous thrombolysis should be given as soon as possible within time window.

Objective: To learn the epidemiological characteristics of coronavirus disease 2019（COVID-19）in Huzhou,so as to provide reference for prevention and control of COVID-19. Methods: All the confirmed cases of COVID-19 in Huzhou,diagnosed according to the COVID-19 Diagnosis and Treatment Plan（Sixth Version Trial）and reported from January 25 to February 7,2020,were recruited. The process of diagnosis and treatment,clinical manifestation,exposure history and close contacts were collected to analyze the epidemiological characteristics. Results: On January 25,the first confirmed cases of COVID-19 in Huzhou was reported. By February 7,totally 10 confirmed cases were reported and no asymptomatic infection was found. They were all imported,including three Wuhan residents,two with a trip to Wuhan,three with a trip to Suizhou,one with a trip to Hangzhou and one with a trip to Thailand（two Wuhan passengers on the same flight）. The ratio of male to female cases was 1∶1. The median age was 32 years old. Seven cases were found when they went to a doctor by themselves,and three cases were found during the quarantine. The main clinical manifestations were fever,dry cough and fatigue. The median time from onset to diagnosis was 3 days. By March 3,all the cases were discharged,with median course of 24 days. There were 312 close contacts,and all of them were released after 14 days of quarantine. Conclusions To prevent imported cases from outside and stop spread inside taken by Huzhou government was proved to be effective. All the COVID-19 cases in Huzhou were imported,mostly from Wuhan. No local cases were reported.

Objective : To analyze the influencing factors for the molecular network transmission clusters of HIV/AIDS, and to provide scientific evidence for the precise prevention and control of AIDS. Methods: A case-control study was conducted. The HIV/AIDS cases reported from January 2017 to June 2019 in Huzhou with strong clustering of HIV molecular transmission were recruited as the case group, and the residents with same gender, similar age ( ±three years ) and HIV negative in the same community and period were matched ( 1∶4 ) as the control group. Demographic characteristics, AIDS related knowledge and sexual behaviors were collected by a questionnaire survey. The Cox regression model was used to analyze the influencing factors for HIV/AIDS molecular network transmission cluster. Results : There was 100 people in the case group and 400 people in the control group, the differences between them in age, sex, marital status, place of residence and educational level were not statistically significant ( P>0.05 ) . The results of multivariate Cox regression analysis showed that awareness of AIDS related knowledge ( HR=0.145, 95%CI: 0.059-0.352 ) was a protective factor for molecular network transmission clusters of HIV/AIDS; men who have sex wth men ( MSM, HR=9.614, 95%CI: 4.645-19.901) , seeking homosexual partners through the internet (HR=16.321, 95%CI: 7.016-32.968) and having syphilis ( HR=3.314, 95%CI: 1.073-10.232 ) were risk factors for molecular network transmission clusters of HIV/AIDS. Conclusions The awareness of AIDS related knowledge, MSM, seeking homosexual partners through the internet and suffering from syphilis are the influencing factors for molecular network transmission clusters of HIV/AIDS.

Objective To analyze the risk factors of postoperative recurrence and metastasis of of BCLC stage A (BCLC-A) hepatocellular carcinoma (HCC).Methods Data of 210 cases of liver resection for HCC were retrospectively analyzed from Nov 2013 to June 2016.Multivariate logistic regression analysis was used to analyze the risk factors for postoperative recurrence.The cumulative survival rates were calculated using the Kaplan-Meier method and the diffrences of the related factors between various groups were analyzed by Log-rank test.Results Univariate analysis showed that alpha-fetoprotein (AFP),neutrophil-lymphocyte ratio (NLR),hepatitis B virus surface antigen (HBsAg) positive and intraoperative transfusion were associated with early recurrence and metastasis after hepatectomy (P ＜ 0.05).Multivariate analysis showed that AFP ＞ 400 ng/ml is an independent risk factor for early postoperative recurrence and metastasis (P =0.008).HBV DNA positive can affect the disease-free survival rate after HCC resection (P =0.030).Conclusion AFP is an independent risk factor for early postoperative recurrence and metastasis.Preoperative HBV DNA positive significantly decreases the disease-free survival rate in HCC patients.

Objective To evaluate the correlation between cerebral blood flow perfusion and memory impairment in patients with severe stenosis of vertebral basilar artery (VBA).Methods 62 cases of patients with VBA stenosis diagnosed by digital subtraction angiography(DSA) in Beijing Tiantan Hospital from September 2016 to March 2017 were enrolled.Mental State Examination (MMSE),Clinical Memory Scale (CMS) test and CT perfusion(CTP) was performed.All patients were divided into memory normal group(n=24,including 1 excellent case,6 above normal cases,and 14 normal cases) and memory impairment group(n =38,including 18 below normal cases,12 periphery cases,8 impaired cases) according to CMS.The ratios of side-to-side period were compared between bilateral mesial temporal lobe and anterior circulation area.The relative time to peak (rTTP),relative mean transit time(rMTY),relative cerebral blood flow(rCBF) and relative cerebral blood volume (rCBV) were calculate.Results The incidence of CTP decompensation in the medial temporal lobe was higher than that in the patients with memory impairment(P＜0.05).The difference of rTTP and rMTT value between the two groups in the bilateral medial temporal lobes was statistically significant (rTFP:(1.131 ±0.037),(1.437±0.139),t=10.520,P＜ 0.05);rMTT:(1.081 ±0.059),(1.281 ±0.174),t=5.423,P＜0.05).Conclusion The patients with VBA severe stenosis are more likely to get memory impairment due to cerebral hypoperfusion.

Objective To evaluate the safety and therapeutic effects of stent retriever-based thrombectomy (SRT) on acute ischemic stroke (AIS) in patients aged 80 years and older.Methods A cohort of 157 AIS patients hospitalized in Capital Medical University Affiliated Beijing Tiantan Hospital were selected for SRT from January 2016 to May 2017.Based on the age,all patients were divided into two groups:groups aged ＜ 80 years and ≥ 80 years.Baseline information including gender,the Modified Rankin Scale (mRS) score,past medical history,smoking history,preoperative National Institutes of Health Stroke Scale (NIHSS),the Alberta Stroke Program Early CT Scores (ASPECTS),intravenous thrombolysis and clinical outcomes were compared between two groups.The informations related to the operation,including time from onset to hospital,door-to-needle puncture time,door-to-recanalization time,SRT complications (symptomatic cerebral hemorrhage,mortality) and good outcome,were compared between two groups.Logistic regression analysis was used to determine whether the age of 80 years and over was a risk factor for adverse prognosis after SRT.Results There were 130 patients in the group ＜ 80 years of age,and 27 patients in the group ≥80 years.No significant differences were found in baseline information between the two groups (all P＞ 0.05).In addition,there were no significant differences in the proportions of the operative information,complications of SRT and the good outcome (all P＞0.05).Furthermore,advanced age (≥80 years) was not a risk factor for adverse outcome after SRT (OR =0.738,95％ CI:0.300-1.813).Conclusions Stent retriever-based thrombectomy is safe and beneficial for patients with acute ischemic stroke,even in patients aged 80 years and over.
