Metabolic syndrome (MS)is a syndrome of multiple metabolic abnormality aggregation,including over-weight,hypertension,glucose and lipid metabolic abnormality and insulin resistance etc.Some researches demon-strated that over 80% EH patients may be complicated with MS,those patients with EH+MS possess higher risk for cardio-and cerebrovascular diseases than pure EH patients.This article made an overview on research about rela-tionship between EH and MS in recent years.

We utilized the mass-acceleration concept according to Newton'a second law of motion to establish a mathematieal model of left ventricular active diastolic force by twodimensional and Doppler echocardiography. Twenty normal control subjects and 31 patients with coronary heart diseases were tested. The results showed that the left ventricular active diastolic force of the patients with coronary heart diseases was significantly lower than that of the control group(P<0.001).The authors believe that left veatricular active diastolic force is a reliable candidates for assessing the left ventricular diastolic function.

Objective To compare two methods of patient controlled epidural analgesia (PCEA) with 0 2% ropivacaine plus fentanyl 2?g?ml -1 with or without background infusion for labor Methods Ninety ASA Ⅰ Ⅱ full term primigravidae in active labor who had a single fetus with vertex presentation and were expected to have vaginal delivery were randomly divided into three groups of 30 each: group A received PCEA without background infusion; group B received PCEA with background infusion and group C received no analgesia of any kind and served as control PCEA included a bolus of 4 ml with a 15 minute lock out When the primigravida was in first stage of labor, an intravenous line was established and 5% glucose normal saline 500 1000 ml was being infused When the external cervical os was dilated to 3 cm, epidural catheter was placed at L 2 3 and a test dose of 4 ml was given 5 min later when no signs of subarachnoid injection was evident, block height was tested by pinprick and another 6 ml was given 30 min later in group B background infusion of 0 2% ropivacaine + fentanyl 2?g?ml -1 was started at a rate of 4 ml?h -1 until the second stage of labor began Maternal vital signs (BP, ECG, SpO 2, P ET CO 2), VAS scores, degree of motor block, drug consumption, side effects of PCEA, gas analysis of umbilical venous blood, progress of labor, and Apgar scores were noted Venous blood samples were taken before PCEA and at the end of first stage of labor for determination of serum epinephrine and norepinephrine levels Results There were no significant differences in Apgar scores, blood gas of umbilical venous blood and the durations of first and second stage of labor among the three groups There were no differences in VAS scores, degree of sensory and motor block, serum concentrations of epinephrine and norepinephrine and percentage of cesarean section between group A and B The percentage of cesarean section was significantly higher in control group than that in group A and B Plasma NE and E concentrations at the end of the first stage of labor were significantly higher in control group than those in group A and B The ropivacaine and fentanyl consumption was less and the incidence of itching and percentage of instrumental delivery were lower in group A than those in group B Conclusions PCEA with 0 2% ropivacaine and fentanyl 2?g?ml -1 was safe and effective It reduces the percentage of cesarean section PCEA without background infusion provides the same level of analgesia as PCEA with background infusion with less drugs and side effects

Objective To investigate the effects of propofol on apoptosis following focal cerebral ischemia-reperfusion in a rat model of reversible middle cerebral artery occlusion(MCAO) .Methods Twenty-four male SD rats weighing 300-500 g were randomly divided into 3 groups: group I sham operation; group Ⅱ MCAO + normal saline; group Ⅲ MCAO + propofol. MACO was produced by insertion of a 2-0 nylon filament with rounded end into internal carotid artery toward brain until resistance was encountered. The depth of insertion was about 2 mm. The filament was withdrawn after 2 h for reperfusion. In group I (sham operation) carotid artery was exposed but no filament was inserted. In group Ⅲ (propofol) intraperitoneal propofol 100 mg?kg-1 was administered 20 min before reperfusion; while in groupⅡ(normal saline) normal saline was given instead of propofol 20 min before reperfusion. At the end of 2 h reperfusion the animals were decapitated and the brain was removed. Apoptosis was identified by TUNEL technique. Cellular structure was examined under light microscope. Results Propofol significantly inhibited neuronal apoptosis following focal cerebral ischemia-reperfusion. Swelling and necrosis of the neurons were significantly attenuated in group III . Conclusion Propofol protects neurons against focal cerebral ischemia-reperfusion in rats.

Objective To evaluate the efficacy and safety of deoxyribonucleotide natrium in the treatment of secondary pulmonary tuberculosis.Methods A total of 94 cases with secondary pulmonary tuberculosis included in this study were dividing into control group and experiment group with each 47 cases.The patients in the both groups were give regular treatment.Patients in the control group were given standard chemotherapy regimen 3HRES/3HRE and patients in the experiment group revieved sodium deoxyribonucleotide injection 150mL+5％injection of liquid glucose 250mL by intravenous drip with once a day.1 time/d,two groups of patients with a cycle of 28d,a total of one cycles of treatment.The clinical efficacy,CA125,CA199,function of liver and kidney,occurrence of adverse reactions were compared between the two groups.Results The clinical efficacy in experiment group was 94.44％,which significant higher than that in control group 75.00％(P<0.05).The serum level of CA125 and CA199 decreased after treatment with experiment group much lower than the control group(P<0.05).Compared with the control group,the ALT,AST,Cr and serum BUN levels before and after treatment,the difference was not statistically significant.The adverse drug reactions was not statistically different between the two groups.Conclusion Deoxyribonucleotide natrium in the treatment of secondary pulmonary tuberculosis was effective with high safety.

Proinsulin(PI)_(AUC) increased,and insulin action index,HOMA-? and △I_(30)/△G_(30) decreased progressively from NGT(n=131) to IGT(n=120) to T2DM(n=107).Obese group had higher HOMA?,Ins_(AUC),C-P_(AUC) and PI_(AUC) than did the non-obese group.

Objective To understand the status quo of the prevention and treatment of hepatitis B in rural area ,to analyze the shortages in prevention and treatment strategy ,to explore the corresponding prevention countermeasures and to provide the scientif‐ic basis .Methods The inhabitants were randomly sampled from 6 natural villages in the rural area of Zhangjiakou as the research subjects .The venous blood HBsAg and HBsAb were detected .The respondents were divided into 2 groups according to the distance of residence place from cities and towns .The distribution differences of HBsAg and HBsAb were compared among different age groups for analyzing the influence of age and public health conditions on the HBV control effects .Results The HBsAg positive rate averaged 5 .92% and the HbsAb positive rate averaged 33 .73% ,with the age increase ,the HBsAg positive rate showed the increas‐ing trend and the anti‐HBsAb showed the decreasing trend ;the anti‐HBsAb positive rate in the inhabitants aged under 15 years near town was higher than those far from town .Conclusion It is needed to increase the input and support intensity to the rural areas in the aspects of finance and manpower ,improve the public health conditions of the rural area with the planned immunity as the main thing ,enlarge the hepatitis B vaccine inoculation range ,strengthen the publicity of HBV harm ,prevention and treatment knowledge , increase the neonatal hepatitis B vaccine inoculation rate and the 24 h timely inoculation rate of hepatitis B vaccine ,accomplish the immune blocking in pregnant women with HBsAg positive ,and preventing the HBV communication during feeding process in in‐fants .

Objective To observe the age-related changes of brain-derived neurotrophic factor(BDNF) and investigate the effects of ginsenosides(GS) on BDNF in nucleus basalis of Meynert(NBM) and cerebral cortex of aged rats. Methods Twenty-four female Wistar rats were randomly divided into 3 groups: young group(3-5 months),aged groups(27 months) and GS group(27 months).GS group was fed with GS from 18 to 27 months.Immunohistochemistry and Imaging analysis were used to show the expression and distribution of BDNF in NBM and cerebral cortex of each group. Results BDNF level of aged group was much lower than that of young group in these two brain areas(P
