Objective: To analyze the clinical features in patients with hypertrophic cardiomyopathy (HCM) combining left ventricular apical aneurysm (LVAA) . Methods: A total of 1194 HCM patients treated in our hospital from 2007-01 to 2013-01 were studied. There were 23 (1.93%) patients combining with LVAA including 19 male and 4 female; coronary artery disease (CAD) was excluded and the patients received echocardiography and coronary angiography (CAG) examinations. Results: There were 21/23 LVAA patients having left mid-ventricular obstruction and 7 of them combining simultaneous left ventricular outflow obstruction.The average pressure gradient in those 21 patients was (56.8 ± 12.9) mmHg and the rest 2 patients suffered from apical hypertrophic cardiomyopathy.The mean maximum thickness of left ventricular wall was (21.8 ± 6.3) mm and the dimension of left ventricle was (39.4 ± 5.2) mm. Electrocardiography showed that 3 patients had paroxysmal ventricular tachycardia;CAG indicated that 6 patients combined with coronary artery muscular bridge at left anterior descending (LAD) artery. The patients were followed-up for (2.7 ± 1.3) years and adverse cardiovascular events occurred in 5 patients during that period. Conclusion: HCM combining LVAA was most frequently happened in patients with left mid-ventricular hypertrophic cardiomyopathy, some of them combining simultaneous left ventricular outflow obstruction and had the higher occurrence rate of adverse cardiovascular events. Early and accurate diagnosis is very important for guiding clinical treatment.

· AIM: To examine the expression of MMP-9 and TIMP-3 mRNA during choroidal neovascularization (CNV) in a murine model and to investigate the role of them in the development of CNV. · METHODS: CNV was induced in C57BL/6J mice by intensive diode laser (810nm) photocoagulation (120mW, 75μm, 0. 1s) of the fundus whereafter eyes were enucleated at 1, 3days, 1, 2, and 4 weeks. The MMP-9 and TIMP-3 mRNA expression were analyzed using in situ hybridization and image analysis system. · RESULTS: Both expression of MMP-9 and TIMP-3 mRNA had dynamic changes. For MMP-9, the expression was 1, 2, 4 wk > 3d > 1d (P < 0.05), whereas TIMP-3 mRNA, 3d, 1, 2, 4 wk>1d (P<0.05). · CONCLUSION: The imbalance between the changes of MMP-9 and TIMP-3 may accelerate the degrading of extracelluar matrix, and then be involved in the pathogenesis of CNV.

OBJECTIVE: To investigate the clinicopathological features and outcomes between node-negative, early-stage cervical squamous cell carcinoma (SCC) and adenocarcinoma (AC) after hysterectomy. METHODS: Patients diagnosed with International Federation of Gynecology and Obstetrics (FIGO) stages I–IIA cervical SCC and AC between 1988 and 2013 were retrospectively reviewed using the Surveillance, Epidemiology, and End Results database. We used propensity score-matching to balance patient baseline characteristics. Univariate and multivariate Cox regression analyses were used for prognostic analyses of cause-specific survival (CSS) and overall survival (OS). RESULTS: A total of 9,858 patients were identified, comprising 6,117 patients (62.1%) and 3,741 (37.9%) patients with cervical SCC and AC, respectively. Compared with cervical SCC, cervical AC cases were more likely to be younger, diagnosed after 2000, white, and have well-differentiated and FIGO stage IB1 disease. For SCC and AC, the 10-year CSS rates were 93.4% and 94.7%, respectively (p=0.011), and the 10-year OS rates were 89.6% and 92.2%, respectively (p<0.001). Multivariate analysis revealed that age, ethnicity, tumor grade, and FIGO stage were independent prognostic factors of CSS and OS, but that histologic subtype was not associated with CSS and OS. In the propensity score-matched patient population, univariate and multivariate analyses also showed that histologic subtype was not associated with survival outcomes. CONCLUSION: Cervical AC has equivalent survival to cervical SCC in node-negative, early-stage disease after hysterectomy and lymphadenectomy.

Objective To investigte the direct medical expense for diagnosis and treatment of pulmonary tuberculosis (TB) patients and its financial burden on family in Minhang District,Shanghai,and to provide evidence for improving TB derating policy and reducing the economic burden.Methods A total of 347 pulmonary TB patients who had completed treatment were investigated by questionnaire.Their receipts on diagnosis and treatment of TB were collected.Ranksum test,linear regression and x2 test were used to analyze medical expenses,influencing factors and social economic burden.Results The median of TB patients' direct medical expenses was 5 657 yuan/person.Linear regression showed that direct medical expenses were related with census,main medical institutions and complications.The main medical institutions have a greater impact on direct medical expenses (β'=-0.217).In the patients,7.5 ％ had high medical expenditures after the deduction of medical reimbursement and derating.And they were mainly distributed among low-income people.Conclusions The diagnosis and treatment expenses of TB patients were relatively high,which resulted in a heavier financial burden to the patient's family.The elderly tuberculosis patients,patients with complications and poor groups should become the focus of medical reimbursement and derating policy.

Abstract: Objective　To evaluate the potential transmission risk of schistosomiasis in Yunnan Province, and to provide strategic basis for the prevention and control. Methods　Based on the prevalence of schistosomiasis, the social and environmental factors that may lead to the epidemic, 1-3 villages from 3 provincial-level and 15 county-level counties (cities and districts) were selected as the evaluated villages in 2021. The risk of schistosomiasis spread was analyzed comprehensively by consulting, reviewing and collecting routine surveillance data of schistosomiasis in the villages, combined with snail and wild feces survey. The risk level was evaluated for the positive snails, positive wild feces, resident infection, average density of live snails and snail frame occurrence rate. Results　Totally 7 snail counties schistosomiasis transmission was blocked of 18 epidemic counties and the rest were eliminated counties. A total of 152 447 snail frames were investigated and 3 043 frames with snails, 15 895 snails were captured and included 15 727 live snails in the 32 evaluated villages. The total area of snail was 58.87 hm2 and the area of reoccurrence was 34.19 hm2 with snail frame occurrence rate of 2.00% and average density of live snails 0.103 2/0.11 m2, and no positive snails were found by loop-mediated isothermal amplification (LAMP) assay. A total of 1 374 wild feces were collected in 27 evaluated villages of 14 epidemic counties, mainly from cattle, dogs, sheep, equine animals, pigs and so on, all of which were negative. According to the risk assessment of epidemic spread, Yongle Village and Yongsheng Village in Eryuan County, Zhiming Village in Chuxiong City were Ⅱ risk, and the rest were Ⅲ risk. Conclusions　Although the risk of transmission is low in Yunnan Province, the risk of transmission and spread still exists. It is necessary to strengthen the risk monitoring, control of snail and effective management of livestock to prevent the rebound of the epidemic.

OBJECTIVE: To explore the distribution and genetic pattern of heteroplasmy of mtDNA control region among Chinese Han population. METHODS: The human mtDNA control region was amplified into 6 amplicons overlapped partially each other. Then these amplicons were analyzed by DHPLC which we developed to detect low heteroplasmic signals. RESULTS: There were 51 heteroplasmic cases (34%) found from different tissues of 150 unrelated individuals of the Chinese Han population. mtDNA heteroplasmy shows non-uniform distribution in various tissues. The highest occurrence of heteroplasmy was in brain tissues (50/150) and myocardium (48/150), the lowest was in bone tissues (22/150). 36 sites of heteroplasmy were identified in our samples. Three sites of mtDNA heteroplasmy rarely co-existed in one individual. No sex differences were detected in the frequency of mtDNA heteroplasmy. No change in the mtDNA heteroplasmy profile was detected of blood samples from the same individuals within 2 years. Individuals older than 41 years showed a heteroplasmy frequency significantly higher than their younger counterparts. Members from the same maternal pedigree in a family can share the same sites of mtDNA heteroplasmy but may have different heteroplasmy contents at those sites. CONCLUSION DHPLC is a highly sensitive technique in detecting heteroplasmy. mtDNA heteroplasmy widely exists in the Chinese Han population. The results shown here could potentially have a guidable value in forensic individual identification and parentage testing.
