Objective To evaluate the curative effect of ultra-early microtrauma drainage in the treatment of hypertensive cerebral hemorrhage. Methods Sixty-one cases of hypertensive cerebral hemorrhage were divided into two groups: the ultra-early group (31 cases; received surgery within 6 hours after the onset) and the control group (30 cases; received surgery between 24 hours and 1 week after the onset).All these cases underwent microtrauma drainage for cleaning the hematoma. Results The effective rate and the marked effective rate in the ultra-early group were 83 9% (26/31) and 67 7% (21/31),respectively,both of which were higher than those in the control group (60% and 40%; ? 2=4 322,4 725;P =0 038, 0 030).The death rate in the ultra-early group (16 1%,5/31) was lower than that in the control group (40%,12/30; ? 2=4 322,P =0 038).Of the life quality of survivors,the values of ADL Ⅰ～Ⅲ accounted for 84 6% (22/26) in the ultra-early group and 55 6% (10/18) in the control group ( ? 2=3 182;P =0 074). Conclusions Ultra-early microtrauma drainage for hypertensive cerebral hemorrhage provides better curative effect and lower death rate than postponed operation.

Objective: To investigate the association of periodontal diseases in pregnant women with preterm birth and low birth weight. Methods: 213 pregnant women aged 22-40 years were enrolled while receiving periodontal examination by 26 weeks of gestation. Periodontal measurements included plaque index(PLI),bleeding on probing (BOP),probing pocket depth(PD) and clinical attachment loss(CAL) were used as the criteria to classify the groups: healthy group(HG; n = 63),gingivitis group(GG; n = 74) and periodontitis group(PG; n = 76). At delivery,birth date and birth weight were recorded. Results: Preterm birth ratio in PG group is higher than that in HG group and GG group(P ＜ 0. 05). Conclusion: Periodontal disease may lead to preterm birth in pregnant women.

Objective To systematically review the mortality burden study of influenza in mainland China. Method "influenza","flu","H1N1","pandemic","mortality","death","fatality","burden","China" and"Chinese" were used as keywords, and a systematic literature search was conducted to identify articles in three English databases (PubMed, Web of Science and Embase) and three Chinese database (CNKI, WanFang and VIP) during 1990-2018 (excluding Hong Kong, Macao and Taiwan). The language of literature was restricted to Chinese and English. The inclusion criteria were human?oriented researches with method based on population, and research indexes included mortality and excess mortality. The exclusion criteria were non?primary research materials, predictive research and research on the burden of avian influenza related deaths. A total of 17 literatures were included, and the basic information to descriptive characteristics, methodology of modeling and the corresponding results were extracted. Results All the 17 studies adopted indirect statistical models, with 14 of which adopted the regression model, and all the research index was excess mortality. All causes (16 studies), respiratory and circulatory diseases (14 studies) and pneumonia and influenza (10 studies) were the main causes of death associated with influenza. Influenza associated mortality burden in the elderly was higher, with the lowest excess mortality rates of all causes, respiratory and circulatory diseases, pneumonia and influenza being 49.57, 30.80 and 0.69 per 100 000 people, and the highest rates being 228.16, 170.20 and 30.35 per 100 000 people, respectively. In the non?elderly, the corresponding lowest rates were-0.27,-0.08 and 0.04 per 100 000 people respectively, and the highest rates were 3.63, 2.6 and 0.91 per 100 000 people, respectively. The influenza?related excess mortality was higher in the north, with a minimum of 7.8 per 100 000 and a maximum of 18.0 per 100 000, and slightly lower in the south, with a minimum of 6.11 per 100 000 and a maximum of 18.7 per 100 000. There were also differences in deaths caused by different influenza virus subtypes, with influenza A(H3N2) and influenza B virus possibly posing a heavier mortality burden. Conclusions Studies on influenza mortality burden is mainly based on indirect model and urban level in China. The mortality burden of influenza in the elderly,the northern and subtype A(H3N2) and B were more severe.

Background and objectivehTe prognosis for patients with lung cancer and brain metastases remains poor, with approximately 6 months of survival, despite active measures atfer treatment. In this study, we determined and ana-lyzed clinical parameters that affect the survival of patients with lung cancer and brain metastases to provide clinical guidance. MethodsLung cancer cases with brain metastases were retrospectively collected during 2002 and 2008 from Shanghai Chest Hospital, Shanghai Jiao Tong University.Kaplan-Meier method andCox regression were performed for univariate and multi-variate analyses, respectively, to explore independent predictors inlfuencing the survival of patients with lung cancer and brain metastases.Results Age, Eastern Cooperative Oncology Group performance status (ECOG PS), metastasis interval, number of metastasis, treatment method, treatment period, symptoms of brain metastases, extracranial metastasis, and brain metastasis order were factors that affect the survival of patients with brain metastases as conifrmed through theKaplan-Meiermethod. Treatment periods and extracranial metastasis were independent survival predictors in patients with lung cancer and brain me-tastasis as indicated byCox proportional hazard model.ConclusionTreatment periods and extracranial metastasis were inde-pendent predictors of survival of patients with lung cancer and brain metastasis. Treatment periods and extracranial metastasis were independent predictors of survival of patients with lung cancer and brain metastasis.

Background and objective 50%-70%of patients with advanced lung cancer will develop bone metas-tases. hTe aim of this study is to establish the nude mice bone metastasis model of lung adenocarcinoma using A549, H1299, SPC-A-1 and XL-2, all of which own different invasion and migration abilities in vitro and supervise the bone metastases by MicroCT. Methods iftfy BALB/C-nu/nu nude mice were grouped into ifve groups on average randomly. Cells of the four cell lines were injected into the letf cardiac ventricle of mice in the four experimental groups (0.2 mL/mouse) respectively;meanwhile, mice in the control group were injected with normal saline (0.2 mL/mouse) in the same manner. Periodical radio-logical examination was carried out to supervise the variation of the mice since the second week atfer injection. When mice in each group became thin obviously, end the experiment of this group. Before the end, pathological sections of bone tissues were made. We classiifed the bone metastatic sites into axial skeleton and limb bone, in order to compare the metastatic rates of these two different parts. hTe bone metastatic abilities of the four cell lines was statistically analyzed by comparing the average time cost in the appearance of bone metastases and the percentage of bone metastases among the experimental groups. Results Different metastatic sites which had been identiifed both by MicroCT and pathological sections appeared in each group of the four experimental groups. By contrast, no metastasis was observed in the control group. hTe percentage of cancer metastasiz-ing to axial skeleton was remarkably higher than the percentage of tumor metastasizing to the limb bone in each experimental group, which was consistent with the clinical regularity and characteristics of skeletal metastases with lung cancer. hTus, the model has been established triumphantly. However, there were no statistical differences in the average time consumed and skeletal metastatic rate among the four experimental groups. Conclusion hTe disruption in the bone can be clearly detected by MicroCT, which is beneift to supervise the osseous metastasis. We successfully developed the nude mice bone metastasis model of lung adenocarcinoma, which will pave the way for exploring novel prevention and therapy strategies clinically. hTe four cell lines varied in invasion and migration abilities in vitro, but there was no statistical difference in the metastatic ability in vivo, and the reason need to be explored further in future.

Objectives To understand the status of studies about influenza economic burden in mainland China and summarize their major results. Methods The words of influenza, flu, cost, economic, burden, effectiveness, benefit, utility, China, and Chinese, were used as search keywords. Journal papers published during 2000-2018 were searched from Chinese electronic databases (CNKI and Wanfang) and English electronic databases (PubMed, Web of science, EconLit and Cochrane Library). The language of literature was restricted to Chinese and English. A total of 23 effective documents were included, and the descriptive characteristics, research indexes and methods included in the literature were analyzed. The monetary unit used in this review is Chinese Yuan (CNY). Results The 23 study sites were mainly in the relatively developed and populous regions. The total cost per capita of laboratory?confirmed influenza,of all age?group was reported in 6 literatures, and only 4 literatures reported it in out?patients (range: 768.0-999.9 CNY), Only one study reported this indicator in inpatients (9 832.0 CNY). One literature reported the total cost per capita of influenza?like illness,, which was 205.1 CNY. And one literature reported that the direct medical cost of inpatients per capita in children under 5 years of age was 6 072.0 CNY while two literature reported this index for the elderly over 60 years of age, ranging from 14 250.0 to 19 349.1 CNY. Four articles reported the economic burden of influenza in urban and rural areas, one of which showed that the related expenses of urban influenza inpatients accounted for 31% of the average annual income, while which for the rural flow was 113%. Conclusion The average economic burden of lab?confirmed influenza case is higher than that of influenza?like illness, and there are differences in outpatient indirect expenses and inpatients direct medical expenses. The direct medical burden for the hospitalized 60?years?and?beyond influenza case group is heavier thar other age group. By region, the influenza associated individual economic burden in rural area is higher than that of urban area..
