ObjectiveTo investigate the feasibility and effectiveness of low central venous pressure (LCVP) in the operation of major hepatic resection.MethodsFourty-eight patients underwent major hepatic resection were randomized into two groups: LCVP and control group.In the LCVP group,CVP was maintained ≤5 cm H2O during the hepatic resection and then returned to normal after resection.In the control group,CVP was maintained normal between 6 -12 cm H20.The duration of hepatectomy,volume of blood loss,volume of blood transfused and renal function were compared between the two groups.ResultsFor the LCVP and control group,the time for hepatectomy was (45 ± 8 ) and ( 35 ± 5 ) min,respectively; the volumes of blood loss were ( 850 ± 160) and (436 ±280)ml,respectively; the blood loss during operation was (490 ± 130) and (270 ± 105 ) ml respectively.The differences were statistically significant (t values were 15.53,7.69 and 17.89 separately,P ＜0.05 ).No significant difference in the renal function was observed before and after the operation ( P ＞ 0.05 ).Conclusion Using LCVP technique during liver resection significantly reduced the operation time,blood loss and blood infusion.And there wa.s no obvious adverse effect on renal function.

Hypertriglyceridemia, and the ectopic deposition of triglycerides, are the risk factors for insulin resistance. To clarify the mechanism of regulations in triglyceride metabolism is an approach to the elucidation of pathogenesis and effective treatment of insulin resistance-related diseases.

Objective To discuss the value of 256 spiral CT dynamic volume scanning in the diagnosis of moyamoya disease.Methods Twenty-three patients with moyamoya disease undergoing 256 spiral CT dynamic volume scanning (moyamoya group) were selected,and 18 patients having cerebrovascular disease symptoms,but the brain artery without stenosis (control group) were also selected.The volume reconstruction (VR),maximum intensity projection (MIP) and cerebral CT perfusion imaging was displayed.The cerebral CT perfusion imaging parameters of anterior,middle,posterior cerebral artery were measured and analyzed.Results VR,MIP could well reproduce lesion location,degree of stenosis and skull base abnormal vascular network change.Compared with control group,the cerebral blood volume (CBV) was increased [(8.46 ±0.91) ml/100 g vs.(2.92 ±0.72) ml/100 g],time to peak (TTP) was increased [(30.27 ±5.02) s vs.(24.83 ±4.07) s] in anterior cerebral artery,and there was significant difference (P ＜ 0.01),but there was no significant difference in the cerebral blood flow (CBF),the mean transit time (MTT)(P ＞ 0.05).Compared with control group,CBV was increased [(8.06 ± 1.05) ml/100 g vs.(6.08 ± 0.56) ml/100 g],MTT,TTP was increased [(6.34 ± 1.01) s vs.(3.83 ± 0.83) s,(32.06 ± 2.55) s vs.(25.83 ± 2.34) s] in middle cerebral artery,and there was significant difference (P＜ 0.01),but there was no significant difference in CBF (P ＞ 0.05).Compared with control group,there was no significant difference in the cerebral CT perfusion imaging parameters of posterior cerebral artery (P ＞0.05).Conclusion 256 spiral CT dynamic volume scanning can be combined with morphology and function imagings,and has important guiding significance for diagnosis of moyamoya disease.

Objective To explore the value of blood lipid and CA125 in identification diagnosis between lung cancer and pulmo‐nary tuberculosis .Methods The blood lipid and serum CA125 levels in 131 patients with lung cancer( Ⅰ - Ⅳ stage) ,53 patients with pulmonary tuberculosis and 60 normal controls were determined by biochemstry ,immunoturbidimetry and electrochemilumi‐nescence immunoassay and was done compared study .Results The serum TC and HDL‐C level in 131 patients with lung cancer were decreased with severity and were lower than in those of in 53 patients with pulmonary tuberculosis(TC :P< 0 .05 ,< 0 .05 ,<0 .01 and < 0 .001 respectively ;HDL‐C :P< 0 .05 ,< 0 .05 ,< 0 .01 and < 0 .01 respectively) .The serum LDL‐C level was no differ‐ences between lung cancer( Ⅰ - Ⅲ stage) and in 53 patients with pulmonary tuberculosis(P> 0 .05) only the lung cancer( Ⅳ stage) was a little increased(P< 0 .05) .The serum TG and ApoB/ApoA1 ratio levels in 131 patients with lung cancer( Ⅰ - Ⅳ stage) were increased with severity and were significantly higher than in those of 53 patients with pulmonary tuberculosis (TG :P < 0 .05 ,< 0 .05 ,< 0 .01 and < 0 .01 respectively ;ApoB/ApoA1 :P< 0 .05 ,< 0 .05 ,< 0 .01 and < 0 .01 respectively) .The level of CA125 in 131 patients with lung cancer was significantly higher than in those 53 patients with pulmonary tuberculosis(P< 0 .001) .Conclusion The serum TC and HDL‐C ,TG ,ApoB/ApoA1 ratio and CA125 levels may be the indexs of identification diagnosis between lung cancer and pulmonary tuberculosis .

OBJECTIVE To investigate the prevalence of extended-spectrum ?-lactamases(ESBLs) and the resistance in Escherichia coli isolates from biliary tract and abdominal cavity.METHODS ESBLs-producers were detected by CLSI Phenotypic Confirmatory Test and susceptibilities were tested by agar dilution method.RESULTS 50.1% Of isolates were ESBLs producers in those isolates.ESBLs producers were highly resistant to ampicillin,cefazolin,cefuroxime,fluoroquinolones,and cefotaxime.The resistant rate to ceftazidime,cefepime,cefoperazone-sulbactam,amikacin,and cefmetazole was less than 40%.None was resistant to meropenem in ESBLs producers.In non-ESBLs producers the resistant rate to ampicillin,cefazolin,cefuroxime,fluoroquinolones was more than 40% and most were susceptible to other antimicrobial agents.The resistant rate to ampicillin,cefazolin,cefuroxime,and ciprofloxacin was significantly higher in ESBLs producers than non-ESBLs producers.CONCLUSIONS With resistance to most of antimicrobial agents,ESBLs-producers were highly prevalent in E.coli isolates from biliary tract and abdominal cavity,so more attention should be paid to survey and detect those strains.

Objective To study the relationship between smoking and the incidence of pulmonary tuberculosis(TB) in Chinese people.Methods The Pubmed database and three Chinese databases such as Wanfang Data,Veipu data(VIP) and China national knowledge infrastructure database (CNKI) were retrieved.The literatures on the relationship between smoking and pulmonary TB incidence in Chinese people published before April 2016 were analyzed.Results Fifteen studies were included,after excluding 1 low quality study,the rest had no statistical heterogeneity.The merged odd ratio (OR) was 1.71,95 ％ confidence interval (CI) 1.51-1.90.Two studies observed the relationship between the amount of cigarettes and TB pathogenesis,but there was heterogeneity and could not be further merged the OR value for conducting analysis.No subgroup analysis of gender was performed in all studies.Conclusion The risk suffering from pulmonary TB in Chinese smokers is 1.71 fold of non-smokers,and smoking increases the risk of pulmonary TB onset.
