Objective: To explore the relationship between non-dipper pattern of blood pressure circadian rhythm and homocysteine (Hcy), carotid atherosclerosis (CAS) in patients with type 2 diabetes mellitus (T2DM). Methods: A total of 240 T2DM patients including 139 male and 101 female were enrolled. According tonocturnal blood pressure falling rates, the patients were divided into 2 groups: Dipper group,n=80 and Non-dipper group,n=160; based on CAS condition, the patients were divided into another set of 2 groups: CAS group,n=119 and Non-CAS group,n=121. Blood levels of Hcy, carotid intima media thickness (CIMT) and 24hSBP, dSBP, nSBP, 24hDBP, dDBP, nDBP were compared between 2 groups in each set; the risk factors of CAS were analyzed. Results: The following indexes were higher in Non-dipper group than Dipper group: Hcy by μmol/L (16.41.0±8.08 vs 12.55±4.07), CIMT by mm (1.00±0.59 vs 0.80±0.30), 24 hSBP by mmHg (138.7±19.2 vs 127.5±15.6), dSBP (139.4±19.2 vs 132.0±16.2), nSBP (136.4±20.0 vs 113.8±15.0), nDBP (74.0±12.0 vs 64.9±9.8), allP<0.01. Multi linear regression analysis indicated that Hcy (β=0.011,P<0.01), nSBP (β=0.021,P<0.01), nDBP (β=0.018,P<0.01) could affect blood pressure circadian rhythm. The following indexes were higher in CAS group than Non-CAS group: CIMT (1.18±0.65 vs 0.69±0.72), age by years (62.33±12.02 vs 59.17±10.80), 24 hSBP (138.2±18.2 vs 131.9±18.9), dSBP (139.5±18.4 vs 134.4±18.5), nSBP (133.9±20.7 vs 123.9±20.9) nDBP (73.3±12.8 vs 68.6±11.0),P<0.05 orP<0.01; while 2 indicators in CAS group were lower than Non-CAS group: SBPF (4.00±7.89 vs 7.66±7.36), DBPF (5.95±8.44 vs 10.19±8.67),P<0.01. Logistic regression analysis showed that age (OR=2.204,P<0.05), nDBP (OR=2.357,P<0.05), SBPF (OR=2.562,P<0.01) were the risk factors for carotid atherosclerosis. Spearman correlation analysis presented that CIMT was positively related to age (0.195,P<0.05) and negatively related to SBPF (r=-0.191,P<0.01). Conclusion: T2DM patients with non-dipper pattern of blood pressure circadian rhythm were usually combining high blood level of Hcy, non-dipper pattern was the independent risk factor for CAS. Restoring blood pressure circadian rhythm is important to prevent atherosclerosis.

Objective To explore the analgesic effect of dicaine combined with penetration en-hancer applied to venipuncture with venous indwelling needle. Methods 60 patients treated with selec-five operation under epidural anesthesia were divided into the control group and the experimental group with 30 patients in each group. The control group was treated with conventional method of venipuncture. The experimental group was externally applied with dicaine combined with penetration enhancer 50 min-utes before the venipuneture in basilic or cephalic vein. Local reactions were observed after venipuncture and the analgesic effects were evaluated with visual analogue scale(VAS 0～100 mm). Results The analgesic ef-fect in the experimental group was obviously better than that of the control group with a significantly lower VAS. The maintaince of analgesic time in the experimental group lasted above 90 minutes. Condusious The analgesic effect of dieaine combined with penetration enhancer can be approved with a very high analgesia rate, its onset time is much shorter than conventional method and maintenance time is much longer.

Objective To observe the relationship between psychological factor(anxiety and depression) and postpartum hemorrhage?mode and duration of labor. Methods Ninety two healthy nulliparas who had no gist of cesarean section were involved in our study. Their psychosis were evaluated with Self-rating Anxiety Scale(SAS) and Self-rating Depression Scale(SDS),according to which they were divided into two groups:high-score group and low-score group.All women were not interfered during the courses of delivery. Mode, duration of labor and postpartum hemorrhage were observed. Results Among the 92 nulliparas observed, the spontaneous delivery rate was 86.96% (80 cases) and the postpartum hemorrhage rate was 10% (8 cases). The scores of SAS and SDS of the low educational level group, the spontaneous group or the non-hemorrhage group were significantly lower than those of the high educational level group, the dystocia group or the hemorrhage group respectively. Moreover, the duration of first and the second stage of the high SAS score group or the high SDS score group was significantly longer than that of the low SAS score group or the low SDS score group,P

Objective To observe the effect of Huanglian Jiedu Decoction ( HJD) for the treatment of dyslipidemia, thus to provide evidence for the prevention and treatment of dyslipidemia with traditional Chinese medicine. Methods A total of 80 dyslipidemia patients were randomized into HJD group ( 50 cases) and simvastatin group ( 30 cases) . After treatment for 4 weeks, blood lipid levels, metabolic parameters and alanine aminotransferase (ALT) levels were detected. Results (1) After treatment, HJD group and simvastatin group both had lower total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol levels (P<0.01 compared with those before treatment), and HJD group had higher high density lipoprotein cholesterol than that before treatment ( P<0.05), but the differences of TC, TG, low and high density lipoprotein cholesterol were insignificant between the two groups ( P>0.05). ( 2) After treatment, uric acid was reduced in HJD group ( P<0.05) , but fasting blood glucose only showed a decreasing trend and the other metabolic parameters stayed unchanged ( P>0.05). The inter-group comparison showed that HJD had lower blood glucose level than simvastatin group, and the difference had statisticall significance ( P<0.05). ( 3) During the treatment, the patients showed good compliance, and had no obvious hepatic or renal damage. Conclusion HJD could reduce TC, TG and low density lipoprotein cholesterol, and increase high density lipoprotein cholesterol of dyslipidemia patients, the effect being similar to simvastatin. HJD could also significantly reduce uric acid of dyslipidemia patients, showing good safety.

Objective To discuss the occurrence of thrombosis in portal system of patients with cirrhotic portal hypertension after devascularization and the methods for treatment and prevention. Methods The clinical data of 113 patients with cirrhotic portal hypertension after the devascularization were collected and analyzed retrospectively and the occurrence time parts as well as the treatment and prevention methods were discussed. Results Among the 113 patients 33 of them were found with thrombosis in their portal system and the occurrence rate was 29.2%. The occurrence time of thrombosis was 2?15 days post?de?vascularization and the median time was 6 days post?operation. Among the 33 cases with thrombosis there were 19 cases of splenic vein thrombosis 10 cases of portal thrombosis and 4 cases of both of them. After the thrombolytic therapy the thrombo?sises in 30 cases disappeared. Conclusions Most of the thrombosises in portal system happen in splenic vein post?devascular?ization. Avoiding clamping the trunk of splenic vein in the operation and taking thrombolytic therapy at the early stage after the operation can effectively prevent the occurrence of thrombosis.
