Objective: To investigate the effect of tanshinone IIA (TSN) on left ventricular hypertrophy (LVH) and cardiomyocyte apoptosis in spontaneous hypertensive rats (SHRs). Methods: A total of 60 SHRs at 8 weeks of age were randomly divided into 3 group: Blank control group, the rats were sacriifced at 8 weeks, TSN group, the rats were treated with TSN at 1 ml/(kg?d) for 18 weeks and Solvent control group, the rats were treated with the solvent at 1 ml/(kg?d) for 18 weeks. n=20 in each group and 15 rats were used for the experiments. The systolic blood pressure (SBP) and left ventricular mass index (LVMI) were examined, cardiomyocyte’s diameter and surface area were measured by HE staining, the apoptosis rate was evaluated by TUNEL method and the apoptosis related protein expression s of Bcl-2, Bax and p53 were determined by Western blot analysis. Results: ①Compared with Solvent control group, TSN group had decreased LVMI (3.23 ± 0.24) mg/g vs (4.58 ± 0.68) mg/g,cardiomyocyte’s diameter (16.13 ± 1.77) μm vs (27.15 ± 3.52) μm and surface area (230.23 ± 69.37) μm2 vs (490.12 ± 118.96) μm2and decreased apoptosis rate (7.45 ± 1.78) % vs (10.61 ± 2.77) %, allP<0.01.②With NAPDH reference correction, compared with Solvent control group, TSN group presented increased protein expression of Bcl-2 (0.97 ± 0.31) vs (0.40 ± 0.11) and decreased Bax (0.37 ± 0.15) vs (1.81 ± 0.44), decreased p53 (0.83 ± 0.18) vs (2.72 ± 0.28), allP<0.05 or P<0.01. The above indexes were similar between TSN group and Blank control group,P>0.05. Conclusion: TSN could inhibit the development of LVH and decrease the cardiomyocyte apoptosis, which might be via up-regulating the protein expressions of Bcl-2 and down-regulating Bax and p53 in SHRs.

Objective To investigate knowledge of cervical cancer,human papillomavirus (HPV) and HPV vaccine and attitude to HPV vaccine among employed urban women in China,and to assess willingness to vaccinate their children.Methods This study was conducted in women from 16 factories or companies in Beijing,Hangzhou,Changsha,Chcngdu and Guangzhou.A questionnaire on cervical cancer,HPV knowledge and HPV vaccine acceptability was administered to participants before and after educational intervention.Results A total of 1 146 women were surveyed from August to November,2011.The awareness rates of cervical cancer,HPV and HPV vaccine were 95.06 ％,27.98 ％ and 12.82 ％,respectively.Only 20.68 ％ knew that HPV was related to cervical cancer.After educatioual instruction,89.26 ％ understood the relationship between HPV and cervical cancer (x2 =93.414,P ＜ 0.001).Only 19.25 ％ women were unwilling to allow their children to be vaccinated.The main reasons were as follows:worried about vaccine safety (23.52 ％),belief that their child was not at risk (21.92 ％),lack of scientific evidence for the vaccine (13.01％),and worricd about vaccine efficacy (12.79 ％).Conclusions In general,there is a high acceptability of HPV vaccine to prevent cervical cancer among employed urban Chinese women after educational intervention.However,some women remain reluctant to vaccinate their children due to concern about vaccine safety and efficacy.

Objective To investigate the clinicopathologic features and prognostic analysis of intrahepatic mucinous cholangiocarcinoma (IMCC) and intrahepatic cholangiocarcinoma (ICC).Methods The retrospective cohort study was adopted.The clinicopathological data of 20 patients with IMCC and 51 patients with ICC who were admitted to the Fujian Provincial Hospital from March 2003 to March 2014 were collected.The observation indicators included (1) clinicopathologic features:gender,age,clinical symptoms (fever,jaundice,abdominal pain and peritoneal effusion),preoperative laboratory examination [alanine transaminase (ALT),aspartate transaminase (AST),direct bilirubin (DBil),carcinoembryonic antigen (CEA),CA19-9 and alphafetoprotein (AFP)],operation methods (radical resection,palliative resection) and pathological features (tumor location,lymph node metastasis,vascular invasion and pathological stage).(2) The follow-up of outpatient examination and telephone interview was performed to detect the survival of patients up to March 2015.Measurement data with normal distribution were represented as x-± s and comparison between groups was analyzed using t test.Count data were analyzed using the chi-square test.The survival curve was drawn by Kaplan-Meier method,and the survival rate was analyzed using the Log-rank test.Result The numbers of patients with fever,jaundice,elevated level of AST and DBil,lymph node metastasis,vascular invasion and numbers of patients with stage 0,Ⅰ,Ⅱ,Ⅲ,Ⅳ were 13,11,10,11,3,1 and4,6,2,6,2 with IMCC,12,10,9,2,22,36 and 0,14,5,3,29 with ICC,respectively,showing statistically significant differences in the above indicators (x2=10.830,8.639,7.672,25.059,8.036,24.765,26.601,P ＜ 0.05).All the patients were followed up for a median time of 14 months (range,1-118 months).The survival time and 1-,3-,5-year survival rates were (55 ± 8)months,94.4％,44.0％,16.7％ in 20 patients with IMCC and (30 ±6) months,36.5％,12.5％,4.0％ in 51 patients with ICC,respectively,showing a statistically significant difference (x2 =8.126,P ＜ 0.05).Conclusion The patients with MICC are more easily complicated with fever,jaundice and liver dysfunction,while they have less lymph node metastasis and vascular invasion,earlier pathological stage and better prognosis compared with patients with ICC.

Objective To investigate the effects of brain-derived neurotrophic factor (BDNF) pretreatment on H9c2 myocardial hypoxia/reoxygenation (H/R) injury, and explore its mechanism. Methods The H9c2 myocardial cells were cul?tured in vitro and (95%O2+5%CO2) oxygen cultured 12 h after (95%N2+5%CO2) hypoxia cultured 4 h to establish the H/R model. The cells were divided into normal control group, H/R group, different concentrations (1, 10, 100μg/L) BDNF pre?treatment in H/R groups and TrkB-inhibitor group (with 100μg/L BDNF and 1∶1 000 TrkB inhibitor pre-treatment in H/R group). The cell survival rate was measured by MTT method in different groups. The lactate dehydrogenase (LDH), creatine kinase (CK), malondialdehyde (MDA) and superoxide dismutase (SOD) content and activity were detected after H/R injury. The apoptotic rate of H9c2 myocardial cells were detected by flow cytometry, and the expressions of TrkB, Bcl-2 and Bax protein were detected by Western blot assay. Results Compared with the normal control group, the survival rate of H9c2 myocardial cells was decreased significantly in H/R model group (P < 0.05), LDH, CK and MDA contents were increased and SOD activity was decreased (P<0.05). The cell apoptosis rate was increased significantly (P<0.05). The anti-apoptosis Bcl-2 protein expression was decreased, pro-apoptosis Bax protein expression was increased in H/R model group (P<0.05). Compared with the H/R model group, the cell survival rates of H9c2 myocardial cells were increased after pre-treatment with different concentrations of BDNF (P<0.05);LDH, CK and MDA contents were decreased and SOD activity were in?creased respectively (P < 0.05). The cell apoptotic rates were decreased (P < 0.05). The expressions of TrkB receptor and Bcl-2 protein gradually increased, while the expression of Bax protein was gradually decreased (P<0.05). The role of BDNF was inhibited by TrkB inhibitor. Conclusion BDNF pre-treatment can promote the cell survival rate of H9c2 myocardial cells after H/R injury, which plays a protective role by inhibiting the cell apoptotic rate and maintaining antioxidant capacity, and associates with BDNF-TrkB signaling pathways.

Objective To compare the surgical effects of transurethal enucleation of prostate (TUEP)with transurethal resection of prostate (TURP) by a retrospective analysis of clinical data.Methods The patients in this study were divided into the groups of TUEP (enrolled in 2010 and 2011,n =77) and TURP (enrolled in 2009,n =27) with prostate larger than 60 g and smaller than 60 g respectively.Comparisons were made between the two groups in operation time,blood loss volume and weight of resected prostate.Results In the group of patients with prostate larger than 60 g,there was no significant difference in prostate weight ((88.5 ± 9.2) g vs.(107.0 ± 15.30) g,P =0.255),operation time ((91.5 ± 8.8) min vs.(118.3 ± 20.2)min,P =0.083),and weight of resected prostate ((48.0 ± 4.6) g vs.(58.4 ± 5.4) g,P =0.32) between the TUEP (53 patients) and the TURP (12 patients) groups.There was significant difference in blood loss ((110.0 ± 16.4) ml vs.(193.3 ± 22.3) ml,P =0.011) between the two groups.In the group of patients with prostate smaller than 60 g,there was no significant difference in prostate weight ((43.1 ± 3.2) g vs.(36.8 ± 3.4) g,P =0.072),operation time ((62.7 ±6.8) min vs.(69.3 ±6.2) min,P =0.431),blood loss ((56 ± 5) ml vs.(110±20) ml,P=0.082),and weight of resected prostate ((26.3 ±2.4) g vs.(23.6 ±2.1) g,P =0.291) between the TUEP (24 patients) and the TURP (15 patients) groups.Conclusion Compared with TURP,TUEP has the advantages of less blood loss in the treatment of patients with prostate larger than 60 g.With the improvement of surgeon' s experience and development of operation techniques,TURP will be replaced by TUEP.In the treatment of patients with prostate smaller than 60 g,the operation modality can be chosen by the surgeon based on his experience and proficiency.

According to the World Report on Disability, compared with the normal children, the enrollment rate of the handicapped children is lower, as well as the rate of in-school children and their chances to get further study. A series of barriers limit the opportunities for these children to accept the mainstream education in such aspects as education policies, systems and services. To solve these problems, the education system and schools have to make some changes so that we could remove all kinds of hardware and software barriers and provide a reasonable adjustment and other support services. Only based on these improvements can we ensure the handicapped children have equal chances to accept education. And the report enlighten us that we should perfect the system construction as well as teacher cultivation and promote community inclusion to ensure the right of education of disabled children.

Objective To observe the efficacy and safety of recombinant tissue type plasminogen activa-tor (rt-PA)for the treatment of the patients with wake-up ischemic stroke (WUS)under the guidance of multimode CT. Methods Eighteen patients with WUS (a thrombolytic group)suitable for intravenous thrombolysis after multimode CT imaging screen at the Department of Neurology,Shiyan Hospital of Integrated Traditional and Western Medicine,Hubei Province from October 2012 to October 2014 were enrolled retrospectively. Twenty patients with WUS (a control group)who underwent multimode CT imaging screen were suitable for intravenous thrombolysis,but because of exceeding time window or rejecting thrombolysis and other reasons without having intravenous thrombolysis from February 2012 to February 2014 were enrolled retrospectively. The control group was treated with conventional therapy and the thrombolytic group was treated with rt-PA (0. 9 mg/kg)intravenous thrombolytic therapy. The indicators including fibrinogen (Fib),coagulation function (prothrombin time [PT ]),activated partial thromboplastin time (APTT ), platelet (PLT ),high-sensitivity C-reactive protein (hs-CRP ),National Institute of Health Stroke Scale (NIHSS )scores,and activities of daily living scores (Barthel index)at before treatment and 24 h,7 and 14 days after treatment were observed respectively. The adverse events and complications were documented and compared with the control group. Results There were no significant differences in Fib,PT,APTT, PLT,hs-CRP,NIHSS score and Barthel index before treatment between the thrombolytic group and the con-trol group (all P>0. 05);at day 7 and 14 after treatment in the thrombolytic group,compared with before treatment,Fib (14 d after treatment),PLT,and hs-CRP were decreased,PT and APTT were prolonged,the NIHSS scores were decreased,and Barthel indexes were increased. There were significant differences (all P<0. 05). At day 14 after treatment,there were significant differences in Fib,PT,APTT,hs-CRP,NIHSS scores,and Barthel indexes (Fib:3. 25 ± 0. 38 g/L vs. 3. 55 ± 0. 28 g/L;PT:15. 7 ± 3. 2 s vs. 12. 9 ± 2. 5 s;APTT:42. 7 ± 3. 5 s vs. 38. 7 ± 2. 6 s;PLT:[189 ± 26]× 109/L vs. [201 ± 23]× 109/L;hs-CRP:5. 7 ± 0. 6 mg/L vs. 11. 3 ± 2. 2 mg/L;NIHSS scores:5. 6 ± 2. 4 vs. 9. 2 ± 4. 5;and Barthel indexes:68 ± 15 vs. 47 ± 5)between the two groups (all P <0. 05). Except 1 patient occurred symptomatic intracerebral hemorrhage after thrombolysis,no other serious complications were observed in the thrombolytic group. One patient in the control group had stress gastric ulcer and bleeding,no symptomatic intracerebral hemorrhage occurred. Conclusion Multimode CT guidance can be used as a reliable imaging evidence for patients with WUS expanding intravenous thrombolytic time window. Under the multimode CT guidance, using rt-PA for intravenous thrombolytic therapy has a certain efficacy.

OBJECTIVETo explore the etiology and clinical characteristics of hypoxic hepatitis (HH) in children.

METHODClinical data of 7 patients with HH in Shenzhen Children's Hospital from January 2011 to March 2014 were retrospectively reviewed.

RESULTSeven cases diagnosed as HH, age from 4 months to 11 years, were admitted to pediatric intensive care unit (PICU), and accounted for 0.32% of patients in PICU during the same period. The primary causes of HH were respiratory failure and cardiac shock caused by severe hand-foot-and-mouth disease, fulminant myocarditis, infant muggy syndrome . Serologic tests for hepatitis B virus, hepatitis C virus, as well as serum antibody and DNA for Epstein-Barr virus and cytomegalovirus were all negative. There was an increase of alanine aminotransferase (ALT) (≥20 time supper limit of normal (ULN), the highest ALT was more than 130 times ULN in all the patients, which was decreased to 2 times ULN from peak within 10 days. There was a significant relationship between ALT and aspartate aminotransferase(AST)in 3 cases(r=1.000, 1.000, and 0.833, respectively, P<0.05), ALT and lactate dehydrogenase (LDH)in 2 cases(r=1.000 and 0.886, respectively, P<0.05), ALT and blood urea nitrogen(BUN)in 1 case(r=1.000, P<0.05), and ALT and creatine kinase(CK)in 1 case(r=0.964, P<0.05). The ALT, AST and LDH returned to normal soon after the primary diseases were controlled.

CONCLUSIONSevere heart failure, hypoxemia, shock, etc. are the leading primary diseases causing HH. The sharp increase in ALT, AST and LDH is the typical laboratory manifestion in HH after the onset, which may decline to normal shortly after the treatment, sometimes complicated with reversible change in BUN or CK.
