Objective To compare the effects of hepatic vein occlusion with tourniquet and Satinsky clamp in reseeting liver tumor involving the second hepatic portal.Methods From Jan 2003 to Jun 2006,180 patients underwent major liver resection with the selective hepatic vascular exclusion (SHVE).According to methods of hepatic vein occlusion,they were divided into two groups:Occlusion with tourniquet(tourniquet group,n=95)and occlusion with Satinsky clamp(Satinsky clamp group,n= 85).In tourniquet group,the hepatic veins were encircled and occluded with tourniquet,and in Satinsky clamp group,the hepatic veins were not encircled and clamped directly with Satinsky clamp.Data regarding the intraoperative and postoperative courses of the patients were analyzed.Results There was no difference between the two groups regarding the operating time,ischemia time,intraoperative blood loss and postoperative complications rate.The dissecting time of hepatic veins was significantly shorter in Satinsky group(6.2?2.4 min vs 18.3?6.2 min).lu the tourniquet group,five hepatic veins(one fight hepatic vein and four common trunk of left-middle hepatic veins)could not be dissected and encircled because of the tumors involving the cava hepatic junction.Another patient's common trunk of left-middle hepatic vein was inadvertently lacerated during the dissection.Hepatic veins in these 6 patients were occluded with Satinsky clamp successfully.Conclusion Occlusion with Satinsky clamping is safer and easier procedure than tourniquets in the resection of liver tumor involving the second porta hepatis.

To investigate the influence of Anxin granules combined with tirofiban on acute myocardial infarction (AMI) Patients after elective percutaneous coronary intervention (PCI). One hundred and twenty AMI patients were randomly divided into treatment group and control group. The patients in the two groups were all given Tirofiban 30mins before PCI . The treatment group was added Anxin granules 30 mins before and after PCI. Tissue factor (TF) and von willebrand factor (vWF) were tested at 6 hours after operation. Syndromatology alteration of traditional Chinese medicine (TCM) and bleeding complications were observed at 4 weeks after operation. Both TF and vWF at 6 hours after operation of the treatment group was lower than the control group significantly (P < 0.01), while the condition of myocardial ischemia at 90 mins after operation of the treatment group was better than control group with significance. The syndromatology alteration of TCM especially spontaneous perspiration and hypodynamia of the treatment group were improved significantly compared to control group 4 weeks after operation. All patients in both groups had no bleeding complications and thrombopenia. The study suggests that Anxin granules combined with tirofiba can improve the clinical efficacy and the endothelial function of AMI patients after PCI with no increase in bleeding events.

OBJECTIVEUsing doubly labeled water method to validate the colmputer science application's activity monitor (CSA) in assessing physical activity of free-living adults in Beijing, in order to develop equations to predict total daily energy expenditure (TEE) and activity related energy expenditure (AEE) from activity counts (AC) and anthropometric variables.

METHODSA total of 72 healthy adults (33 males and 39 females, mean age 43.6 +/- 4.0 yr) were monitored for 7 consecutive days by CSA. TEE was simultaneously measured using doubly labeled water method. Average AC (counts/min(-1)) was compared with TEE, AEE and physical activity level (PAL).

RESULTSPhysical activity determined by AC was significantly related to data on energy expenditures: TEE (r = 0.31, P < 0.01), AEE (r = 0.30, P < 0.05), and PAL (r = 0.26, P < 0.05). Multiple stepwise regression analysis showed that TEE was significantly influenced by gender, fat-free mass (FFM) or BMI and AC (R(2) = 0.52 - 0.70) while AEE was significantly influenced by gender, FFM and AC (R(2) = 0.25 - 0.32).

CONCLUSIONAC from CSA activity monitor seemed a useful measure in studying the total amount of physical activity in free-living adults while AC significantly contributed to the explained variation in TEE and AEE.

Objective:To investigate the effect of bedside ultrasound in measuring the gastric residual volume in postoperative patients with rheumatic heart disease complicated with cachexia with enteral nutrition support.Method:From June 2015 to May 2017,60 patients with rheumatic heart disease complicated with cachexia who admitted in ICU were randomly divided into two groups,group A (routine enteral nutrition plan plus ultrasound monitoring GRV)and group B (routine enteral nutrition plan plus withdraw every 4h to monitor the GRV),to guide the implementation of enteral nutrition.Results:There was significant difference in Hb,TP and ALB levels between the two groups (P ＜0.05).The nutritional status of group A was better than that of group B.The incidence of gastric retention and pulmonary infection in group A was significant lower than group B (P ＜0.05).The length of target feeding time and ICU stay had a statistically difference in group A and group B [(3.02 ± 0.78) d vs (4.89 ± 0.69) d,t=2.278,P=0.019] and [(10.41 ± 1.98) d vs (11.39 ± 1.75) d,t=2.384,P=0.015].Conclusion:The application of bedside ultrasound to monitor the gastric residual volume can be an accurate method to guide enteral nutrition in postoperative patients with rheumatic heart disease complicated with cachexia,which can improve the nutrition status,shorten the length of target feeding time and ICU stay and reduce enteral nutrition-related complications.

Objective To explore the current status of the prenatal care quality and the influencing factors in Hangzhou City. Methods We used sociodemographic characteristics questionnaire and the Chinese version of QPCQ to investigate 383 pregnancy women who were at 36 weeks' gestation or greater by convenient sampling method from September to December in 2016. Results A total of 350 questionnaires were valid. The average age of 350 samples was (29.71±3.67) years old. There were 231 primiparas which accounted for 66.00％. Among them, 196 (56.00％) were satisfied with the prenatal care they received, and 153 (43.70％) think general, and only 1 (0.30％) felt unsatisfied. The score of the Chinese version of QPCQ was 3.61±0.50. The item "My prenatal care professional (s) always answered my questions honestly" had the highest scores of 4.10±0.62, while "My prenatal care professional (s) did things hastily" had the lowest scores of 2.44±0.96 . By multiple linear regression analysis, those people who had more visiting time (β' = 0.21, P<0.01), less waiting time (β' = -0.18, P<0.01) and the cognition of the essentiality of pregnancy school (β' = 0.12, P=0.02) were more likely to give higher regards for the quality of prenatal care. Conclusion Sufficient time scored relative lower in the whole questionnaire. So, hospitals could take efforts to shorten the waiting time by promoting the hospital process optimization, making good use of this period time and other strategies, so as to improve the quality of prenatal care.

OBJECTIVETo construct a gene knock-out mutant of response regulator named RevS in Streptococcus suis serotype 2 virulent strain 05ZYH33, and to investigate the effects of its deletion on the biological characters of this pathogen and the pathogenesis to mice and piglets.

METHODSRecombinant gene knock-out vector consisting of Spc(r) cassette was constructed and flanking was constructed consisting of Spc(r) cassette with flanking homology regions to the RevS genes while the isogenic RevS-deficient mutant was screened by allelic replacement. The effects of RevS deletion on the basic biological characters of 05ZYH33 including growth stability, colonial morphology, haemolysis, Gram staining, growth curve and protein expression were examined in vitro. The mice and piglets were infected with 10(8) CFU wild virulent and mutant isolates.

RESULTSPCR analysis confirmed that the coding genes of RevS were replaced completely by Spc(r) cassette and the basic biological characters of 05ZYH33 did not undergo any apparent change. Balb/c mice infection assay indicated that RevS play a role in the pathogenesis of Streptococcus suis infections, while no remarkable difference was observed in the piglets' pathogenesis infection rates between mutant isolates deltaA05ZYH33 and wild-type isolates 05ZYH33.

CONCLUSIONThe mutant of Streptococcus suis 05ZYH33 response regulator was successfully constructed, while the mutation did not obviously affect the bacterial biological characters, while the knock-out mutant of RevS was shown to be attenuated in pathogenesis to mice and piglets.

OBJECTIVETo determine the prevalence of Streptococcus suis and major pathogenic serotypes in middle part of Jiangsu province.

METHODSTonsillar specimens from 303 slaughtered pigs aged 6 to 8 months were investigated for the presence of Streptococcus suis and major pathogenic serotypes by polymerase chain reaction (PCR) method. Bacteriological examination compared with molecular genetics identification for three Streptococcus suis isolates were also done.

RESULTSThe overall carrier rate of Streptococcus suis was up to 88.0%, with the percentages of serotype 1(14), 2(1/2), 7 and 9 were 9.6%, 8.5%, 11.3% and 29.5% respectively in 2005. While in 2006, the prevalence of Streptococcus suis was 82.5%, with capsular types 1 (14), 2 (1/2), 7 and 9 were accounted for 17.6%, 2.4%, 25.8% and 20.0% of all the specimens. All the three isolates belonged to Streptococcus suis serotype 2,named 2a, 2f and 14e, which exhibiting the virulent phenotype cps2+/gdh+/mrp-/lepf-/sly-/fbps+/orf2+/89k-, cps2+/lgdh+/mrp-/epf-/sly-/fbps-/orf2-/89k- and cps2+/gdh+/mrp-/epf-/sly-/fbps/orf2-/ respectively. These isolates were all susceptible to amoxicillin, ampicillin, penicillin and resistant to amikacin and tetraycline. Clinical signs were not noted in BALB/c mice and rabbit.

CONCLUSIONPrevalence of the Streptococcus suis among the healthy herds in the areas was very high, with various capsule types of Streptococcus suis involved in the same herds, and the virulent phenotype of these 3 isolates were very different from those prevalent Streptococcus suis serotype 2 virulent isolates frequently discovered from the epidemic areas.

OBJECTIVETo compare the effects of selective hepatic vascular exclusion (SHVE) and Pringle maneuver in resecting the liver tumors involving the second porta hepatis.

METHODSFrom January 2000 to October 2005, 2100 liver tumors were resected, among which 235 tumors adhered to or were very close to one or more hepatic veins. Both SHVE and Pringle maneuver were used to control the blood loss during the hepatectomy. They were divided into two groups: SHVE group (125 cases) and Pringle group (110 cases). Data regarding the intra-operative and postoperative courses of the patients were analyzed. SHVE group included total SHVE (clamping of the porta hepatis and all major hepatic veins) in 25 cases and partial SHVE (clamping of the porta hepatic and one or two hepatic veins) in 100 cases. Three methods were used to occlude hepatic veins: be ligated with suture, be encircled and occluded with tourniquets and be clamped with Shatinsky clamps directly.

RESULTSThere was no difference between the 2 groups regarding the age, sex, tumor size, cirrhosis and HBsAg positive rate, ischemia time and operating time (P > 0.05). Intra-operative blood loss and transfusion requirements were decreased significantly in the SHVE group. Hepatic veins ruptured with massive blood loss in 14 and air embolism in 3 in Pringle group, but there was no massive blood loss and air embolism in SHVE group. Postoperative bleeding, reoperation, liver function failure and mortality rate were higher in Pringle group (P < 0.05), ICU stay and hospital stay were longer in Pringle group (P < 0.05).

CONCLUSIONSSHVE is much more effective than Pringle maneuver for controlling intraoperative bleeding. It can prevent massive blood loss and air embolism resulting from hepatic veins ruptured and can reduce the postoperative complications rate and mortality rate. Clamping the hepatic veins with Shatinsky clamp is safer and easier than encircled and occluded with tourniquets.

OBJECTIVETo study the expression and possible roles of proto-oncogene c-erbB2 during the initiation growth of primordial follicles.

METHODSOvaries were collected from 2-day-old SD rats and cultured in the Waymouth culture system. In-situ hybridization, RT-PCR and immunohistochemistry were performed to assess the expressions of c-erbB2 mRNA and protein during the initiation growth of primordial follicles and after the effect of EGF. Western blot was used to observe the PCNA, p-ERK1/2 contents and correlation analysis was used to study the correlation relationship between contents of p-ERK1/2 and expressions of c-erbB2 mRNA at the same time of the primordial follicles growth.

RESULTSPCNA protein levels appeared to be more intense during the initiation growth of primordial follicles, EGF could promote the proliferation and differentiation of the primordial follicles. c-erbB2 mRNA existed in the oocytes endochylema and ErbB2 existed in the oocytes membrane, the expressions of c-erbB2 mRNA and ErbB2 appeared to be more intense when primordial follicles were cultured for 8 d than cultured for 0 d in the Waymouth culture system and were further increased with 50 ng/ml EGF for 4 d and 8 d. The same results were observed by RT-PCR, too. p-ERK1/2 protein levels were consistent with the changes of c-erbB2 mRNA and protein. Furthermore, Spearman rank correlation analysis showed there was a significant positive correlation relationship between the changes of p-ERK1/2 and the changes of c-erbB2 mRNA during the primordial follicles growth and after the effect of EGF (rs = 0.900, P < 0.05).

CONCLUSIONIt was suggested that proto-oncogene c-erbB2 may be play an important role during the initiation growth of primordial follicles with EGF, and it is indirectly suggested that c-erbB2 promotes the development of the primordial follicles via ERK-MAPK signal transduction.

OBJECTIVESTo evaluate the effect of Happy 10 program on the promotion of physical activity, physical growth and development of primary-school students, and on obesity control and prevention.

METHODSTwo similar primary schools from one district of Beijing, China were selected, one as an intervention school and the other as a control school. Happy 10 program was implemented at least once every school day in the intervention school for two semesters, whereas no intervention was adopted in the control school. The information on energy expenditure and duration of physical activity was collected by a validated 7-day physical activity questionnaire. Height and weight were measured by trained investigators following the standardized procedure. Energy expenditure and intensity of each Happy 10 session was measured by a physical activity monitor.

RESULTSThe average energy expenditure and duration of total physical activity per day among students in the intervention school increased significantly from 15.0 to 18.2 kcal/kg, and 2.8 to 3.3 h respectively, whereas the figures significantly decreased in the control school. There was a significant difference in change of weight and BMI between girls in the intervention and control school (2.4 kg vs 4.6 kg, -0.47 kg/m2 vs 0.66 kg/m2). The prevalence of overweight and obesity in the intervention school decreased by 0.4%-5.6%, as compared to the increase by 0.6%-4.5% in the control school. The average energy expenditure and intensity per 10-minute session ranged from 25.0-35.1 kcal, 4.8-6.2 kcal/kg/h respectively in grades 1-5.

CONCLUSIONHappy 10 program provides a useful strategy to promote physical activity among school children and also plays a positive role in building up physical growth and development of girls.
