Totally 1136 individuals aged over 40 underwent health check up in March to May 2009. Fasting blood glucose, 2-h post-challenge blood glucose, glycated hemoglobin A1c ( HbA1c), total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and serum uric acid were measured. The diagnosis of metabolic syndrome was based on the International Diabetes Federation Criteria. The results shows that total body fat, region body fat indices, blood pressure, blood glucose and serum uric acid levels increased with the age ( P < 0.01) . The prevalence rate of metabolic syndrome in this group of individuals were 15. 1% (171/1136) , and increased with age (P<0.01). The most common combination of metabolic syndrome was central obesity-hypertension-dyslipidemia (40. 9% , 70/171). Unconditional logistic regression revealed that waist-hip-ratio, body mass index and uric acid were the risk factors for metabolic syndrome.

Methods Clinical data of all 155 newborn HD cases were analyzed. Protocols were compared before and after May 2000. Results Barium enemas, anorectic manometry and rectal biopsies confirmed the diagnosis of HD in 155 newborn cases. Two stage radical procedure was performed in 107 cases , and one stage in 48 cases. One hundred and forty-seven cases were cured. Postoperative pneumonia occurred in 25 cases, wound dishences in 8 cases with 8 deaths. There was substantial difference in the incidence of complications, hospital stay and mortality between the two periods. Conclusions (1) Gastrointestinal perforation in neonatal HD cases should be managed by rectal biopsies during the exploration. (2)Different surgical treatment should be adopted in HD cases less than one month of age.

ObjectiveTo investigate the relationships between traditional Chinese medicine(TCM) syndrome differentiation and serum cystatin C(Cys-C) and homocysteine(Hcy) in patients with chronic heart failure(CHF). Methods 115 cases with CHF admitted into the Department of Cardiology of the First Affiliated Hospital of Zhejiang Chinese Medical University were selected in the CHF group, and 30 cases who had taken health examination in the same period were chosen in the healthy control group. According to the TCM syndrome differentiation, the CHF cases were subdivided into four groups with different types of syndrome: 30 cases of deficiency of both Qi and Yin syndrome, 30 cases of Qi deficiency syndrome and blood stagnation syndrome, 30 cases of heart and kidney Yang deficiency syndrome and 25 casesof flooding due to Yang deficiency syndrome. The serum levels of Cys-C and Hcy in different groups were tested, and the relationships between TCM syndrome differentiation and serum Cys-C and Hcy were analyzed by using Spearman rank correlation analysis.Results The serum levels of Cys-C and Hcy in the patients with CHF were significantly higher than those in the healthy control group〔Cys-C(mg/L):1.24±0.34 vs. 0.77±0.22, Hcy(μmol/L):18.66±4.57 vs. 11.65±3.21,bothP<0.05〕. Compared with the healthy control group, the serum levels of Cys-C and Hcy in the above four groups of different syndromes had a tendency of gradual elevation in the sequence as follows: deficiency of both Qi and Yin, Qi deficiency and blood stagnation, heart and kidney Yang deficiency and flooding due to Yang deficiencygroups〔Cys-C(mg/L):1.02±0.27,1.09±0.31,1.32±0.22, 1.59±0.25; Hcy(μmol/L): 14.94±2.20, 17.66±3.04, 19.79±3.48, 22.96±5.31〕, and the elevation in levels of flooding due to Yang deficiency group was the most prominent compared with that in other groups(P<0.05). The correlation analyses showed that different types of TCM syndrome in patients with CHF were positively correlated with the levels of Cys-C and Hcy(r1=0.73,r2=0.79,bothP<0.05).ConclusionThe changes of serum Cys-C and Hcy levels are consistent with the evolution of regular pattern of TCM syndrome differentiation in patients with CHF, and these two markers can be regarded as the objective indicators of TCM syndrome differentiation of CHF.

AIM: To observe the inhibitory effect of recombinant human endostatin (rhES) on plaque angio-genesis, and to explore the regulatory mechanism of Dll4 /Notch pathway in the anti-angiogenic effect of rhES.METH-ODS: Male Wistar rats were randomized into 3 groups: normal control group (N group), atherosclerotic model group (AS group), and rhES treated group (AS +rhES group).The rats in N group were fed a normal diet, while the remaining 2 groups were established to atherosclerotic rat model via high-cholesterol diet, intraperitoneal injection of vitamin D3 and aor-tic balloon injury.The rats in AS +rhES group received intraperitoneal injection of rhES.The blood total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), C-reactive protein (CRP), interleukin-1 (IL-1) and troponin I (TnI) were measured.The atherosclerotic abdominal aortas were taken for pathological observation.Immu-nohistochemical staining was used to measure the density of neovessels in the plaques, which were marked by CD31.The protein levels of Dll4 and Notch1 in the aortas were analyzed by Western blot.RESULTS: The levels of blood TC, TG, LDL-C, CRP and IL-1 in AS group and AS +rhES group were much higher than those in N group (P <0.05), and no sta-tistical difference between AS group and AS +rhES group was observed.The expression of CD31 in AS group was the high-est among all groups.Compared with AS group, the density of neovessels in the plaques of AS +rhES group decreased sig-nificantly (P <0.05).The protein expression of Dll4 and Notch1 in AS group was lower than that in N group (P <0.05). Compared with AS group, the protein expression of Dll4 and Notch1 increased significantly (P <0.05).CONCLUSION:rhES has the ability to inhibit plaque angiogenesis in rats.The activation of Dll4 /Notch pathway may be the mechanism of rhES in inhibiting plaque angiogenesis.

Objective To observe the pathophysiological change of right heart remodeling model of beagle dogs caused by tricuspid regurgitation. Methods Six beagle dogs were separated to TR group and sham operation group randomly and equally. The anterior and posterior leaflets of tricuspid valve of beagle dogs from TR group were cut off under direct vision on the beating heart. The echocardiography data were measured pre-operation and post-operation 3, 6, 12 months respectively and autopsy results were acquired after the sacrifice of two animals who had been raised for 18 months. Results The operation was successful and survival 100%. The weight of TR group increased, and the echocardiography showed right atrium and ventricle enlargement and right heart dysfunction. The autopsy of TR group found myocardial fibrosis , liver cirrhosis and ascites. All of the results indicated the occurrence of right heart remodeling and right heart failure. There is no significant difference in sham operation group before or after operation. Conclusion The myocardial fibrosis is one of the pathological basis of right heart remodeling.

Objective To provide theoretical and experimental proof for selecting and implying Tourette's syndrome(TS) animal models, validities of four TS models induced by chemical factors were compared. Methods Four TS models,namely AMP model,APO model,DO1 model and IDPN model were built up by using different chemical modeling agents. Through detecting spontaneous movement, climbing time and monoamine transmitters levels in striatum, four TS animal models were compared and evaluated from three levels of validities-face, prediction,construct. Results Compared with control group, spontaneous movement times raised ( t = 4. 746, P =0. 000) and level of DOPAC ( (0.99 ± 0. 177 ) ng/mg) in striatum increased (P = 0.029 ), and level of NE in striatum decreased in AMP model group( (0.11 ± 0.033 )ng/mg, P = 0.012). Compared with control group, climbing time prolonged (P = 0. 004) and levels of DA ( ( 10. 19 ± 1.23 ) ng/mg), 5-HT ( ( 0. 54 ± 0.08 ) ng/mg) in striatum raised(P=0. 019, P=0. 002),at the same time ,levels of DOPAC( (0.63 ±0.11 )ng/mg),HVA ((0.45 ±0.04 ) ng/mg) in striatum reduced (P ＜ 0.01 ) in APO model group; Compared with control group, levels of DA ( ( 13.66 ± 1.55 ) ng/mg), DOPAC( (0.80 ±0. 11 ) ng/mg), HVA( ( 1.04 ± 0.14) ng/mg) grew downwards in striatum of DOI model mice(P=0.029,P=0.001, P= 0.004). Compared with control group, level of 5-HT in striatum increased in IDPN300 group ( (0.77 ± 0.09) ng/mg, P = 0.031 ). ConclusionFace validity of AMP model is temporal and that of IDPN model is steady and persistent. AMP model,APO model and DOI model possess predictive validity. AMP model,APO model,DOI model and IDPN model have potentiality of becoming construct validity model.
