Objective To investigate the variations of serum levels of visfatin in pregnant women with different types of glucose intolerance and the associations with insulin resistance.metabolic parameters and newborn birth weight.Methods Totally,120 pregnant women in late trimester were divided into 3 groups according to the results of 50 g glucose challenge test(GCT)and 75 g oral glucose tolerance test:GDM group(n=45),GCT(+)group(n=20),and NGT group(n=55).Fasting levels of visfatin,insulin,total cholestrol and triglyceride were measured and the newborn birth weight was recorded.Results The serum visfatin level was significantly elevated in GDM group compared with the NGT group[(374.9±23.1)ng/ml vs(308.9±16.8)ng/ml,P＜0.05],but no significant difference was shown when compared with the GET(+)group[(346.5±23.1)ng/ml].Furthermore,serum visfatin levels had no relationship with insulin resistance,metabolic parameter and newbom birth weight.Conclusions Visfatin is elevated in GDM women and closely related with GDM,but not with insulin resistance,metabolic parameters and newborn birth weight.

Objective To explore the glucose and liplid metabolism changes of pregnant rats and the birth weight of their offsprings due to pregnancy malnutrition,including overnutrition and undernutrition.Methods Thirty pregnant Wistar rats were randomly divided into three groups on the day of conception,the high-fat-diet group,normal control group and 50％ food-restricted diet group.Increase of body weight and serum level of triglycerides,high-density lipoprotein,low-density lipoprotein,oral glucose tolerance test (OGTT) and insulin release test(IRT) levels during pregnancy were measured.The birth weight of offsprings was recorded within 12 h after birth.One-way ANOVA,LSD or Dunnett T3,and Chi-square test were applied for statistical analysis.Results The body weight at late pregnancy and the level of triglycerides and low-density lipoprotein were significantly increased in the high-fat-diet rats compared to normal control ones [(1.68±0.13) mmol/L vs (0.78±0.08) mmol/L,(0.57±0.04) mmol/L vs (0.35±0.07) mmol/L; both P＜0.01].While the level of high-density lipoprotein of high-fat-diet rats was lower than that of the normal control rats [(0.56±0.06) mmol/L vs (1.09±0.08) mmol/L,P＜0.05].The level of triglycerides,low density lipoprotein and high density lipoprotein in 50％ food restricted group [(0.47±0.06) mmol/L,(0.21±0.06) mmol/L and (0.42±0.05) mmol/L] were lower than the control group (all P＜0.05).Impaired glucose tolerance,abnormal OGTT and IRT results were found in both high-fat-diet and 50％ foodrestricted diet rats.The fasting plasma glucose level in high-fat-diet group was significantly increased in late pregnancy compared to the control [(6.63±0.53) mmol/L vs (4.90±0.26) mmol/L,P＜0.05],while there was no significant difference between rats in 50％ food-restricted diet [(4.18±0.26) mmol/L]and control group (P＞0.05).There was no statistical difference in fasting serum insulin level among the three groups.The average birth weight was significantly increased in high-fat-diet rats than in the control group [(6.14±0.31) g vs (5.73±0.26) g,P＜0.05],and the incidence of macrosomic newborn rats in the high-fat-diet group was also higher than that of the control group [19.2 ％ (19/99)vs 7.84％(8/102),P＜0.05].The birth weight of offspring in 50％ food-restricted diet group was decreased with their average birth weight of (4.54±0.23) g,which was lower than that of the control group (P＜0.05).The incidence of macrosomic [13.40％ (11/76)] and low birth weight newborn rats [15.90％ (13/76) vs 3.92％(4/102)] in food-restricted diet group were both higher than in the control group (P＜0.05); and smaller number of offsprings was obtained than the control group (76 vs 102,P＜0.05),the number of offsprings in high-fat-diet group was 99,which was less than the control group without statistical difference (P＞0.05).Conclusions Pregnancy malnutrition,including overnutrition and undernutrition,may affect the lipid metabolism and glucose tolerance of pregnant rats,leading to insulin resistance,and may also contribute to the abnormal birth weight of the offspring,including macrosomia and low birth weight.

Changes of glycosaminoglycans in cerebrum, brainstem and cerebellum were measured in rats with hepatic encephalopathy induced by thioacetamide. It was foundthat the contents of glycosaminoglycans in brainstem and cerebrum were lowered markedlythan that of the normal control, but no significant difference of glycosaminoglycans werefound in cerebellum. The results suggested that the metabolism of glycosaminoglycans incerebrum and brainstem was disturbed when hepatic encephalopathy occured, and thatthe pathogenic mechanism of hepatic encephalopathy was related to the alterations of gly-cosaminoglycans in brain as a result of hepatic insufficiency.

Changes of pulmonary vascular permeability and blood gas were measuredin rats of experimental fulminant hepatic failure induced by thioacetamide. The resultsshowed that the pulmonary vascular permeability to Evans Blue in rats of fulminant he-patic failure with hepatic enphalopathy was markedly increased than that of normalcontrols (P

OBJECTIVETo evaluate the clinical efficacy of warming-needle moxibustion on cervical headache.

METHODSSixty-one patients of cervical headache were randomly divided into a warming-needle moxibustion group (30 cases) and an acupuncture group (31 cases). Tianzhu (BL 10), Fengchi (GB 20), Wangu (GB 12), Tianyou (TE 16), Hegu (LI 4), Taichong (LR 3) and Zulinqi (GB 41) were selected in the two groups. Patients in the acupuncture group were treated with acupuncture; patients in the warming-needle moxibustion group were treated with warming-needle moxibustion at Tianzhu (BL 10), Fengchi (GB 20) and Wangu (GB 12) and acupuncture at the remaining acupoints. The treatment was given once every other day, 3 times a week, and totally 4-week treatment was given. The duration and frequency of headache, numerical rating scale (NRS) of headache and cervical range of motion (ROM) were compared before and after treatment in the two groups; also the efficacy of the two groups was evaluated.

RESULTSAfter treatment, the duration and frequency of headache, headache NRS.and cervical ROM score were improved in both groups (all P < 0.05), which were more significant in the warming-needle moxibustion group (all P < 0.05). The total effective rate was 84.3% (25/30) in the warming-needle moxibustion group, which was significantly superior to 61.3% (19/31) in the acupuncture group (P < 0.05).

CONCLUSIONThe warming-needle moxibustion presents significant efficacy on cervical headache, which can obviously improve headache symptoms and cervical ROM.

36 gestational weeks. Venous blood was taken to measure the level of glycosylated hemoglobin. Results The mean value of glycosylated hemoglobin in normal pregnant women was 4.1%(95%CI=2.5～5.7%). No difference was shown among different gestational weeks. Conclusions The normal value of glycosylaed hemoglobin in pregnancy is 2.5%~5.7%.

Objective To investigate whether insulin resistance is a cause of pregnancy induced hypertension (PIH). Methods All patients who had abnormal 50g glucose screening test accepted 75g oral glucose tolerance test (OGTT) and insulin sensitive index (ISI) was calculated. These patients were followed up and divided into two groups (PIH group and normal pregnancy group) at third trimester of pregnancy. The difference of ISI between the PIH group and normal pregnancy group was compared. Results Fast blood glucose, fast blood insulin and ISI were (4.2?0.7)mmol/L vs. (3.8?0.7)mmol/L, (107.8?48.8)pmol/L vs. (50.4?40.5)pmol/L, and -3.25?0.27 vs. -2.58?0.66 in PIH group and normal group, respectively ( P 0.05). Conclusions Insulin resistance during second trimester of pregnancy may be one of the causes of pregnancy induced hypertension.

Objective The aim of the paper is to investigate the alteration of the physical-chemical properties and disinfection effect of electrolyzed-oxidizing water during storage, and to provide theory support for its application. Methods A typical electrolyzed-oxidizing water was stored under a closed and light condition for 66 days and its physical-chemical parameters and disinfection effect were measured at fixed periods. Results The results showed that the chlorine loss of the electrolyzed-oxidizing water was quite fast and reached 50% and 100% after 10 days and 66 days of storage period respectively, the pH value was quite stable, from 2.5 to 2.47. The oxidation-reduction potential(ORP) of the water decreased slowly only from 1 146 mV to 1 100 mV within 45 day, but decreased rapidly after 45 days of storage. The results also showed that the inactivation of Bacillus subtilis var niger spores by the electrolyzed-oxidizing water also decreased rapidly after one week of storage,from 100%(the first week) to less than 90%(after 10 days). Conclusion The electrolyzed-oxidizing water can keep its strong disinfection effect after 7-10 days of storage. It was believed that the chlorine loss from the electrolyzed-oxidizing water was the main reason for the decrease of its disinfection effect during storage.

Objective To investigate the relationship between impaired glucose test and insulin resistance in pregnancy. Methods Ninety-three pregnant women who had one abnormal result among 4 of oral glucose tolerance test (OGTT) and 179 pregnant women who had normal results of OGTT from 11 hospitals of Shanghai during May 1999 to Aug 1999 were included. Insulin release test were performed at the same time. Insulin sensitive index (ISI), islet secretive function index (IFI) were calculated. Area under sugar curve (SAUC)?area under insulin curve (IAUC)?ISI? IFI?fast plasma sugar(PGO) and fast plasma insulin (INO) were compared between two groups. Results PGO, INO, SAUC, IAUC and ISI of the IGT group and control group were(5.1?1.0)mmol/L vs(4.3?0.4)mmol/L?(142?77) pmol/L vs (114?40)pmol/L?(1186?437) pmol/L vs (1058?407)pmol/L?(23?4) mmol/L vs (18?3)mmol/L and 30?20 vs 22?24 respectively, the differences were significant(P0.05). Conclusions Insulin resistance is one of the causes of impaired glucose test in pregnancy.

(0.05,) respectively). Conclusions OGTT ignoring the third-hour plasma specimen is easy to be administered, has a low rate of undiagnosis and can be used in the diagnosis of GDM.
