ObjectiveTo evaluate the therapeutic effect of combined portoazygous devascularization and shunt on portal hypertension. MethodsThe data of 56 cases of portal hypertension treated with portoazygous devascularization and shunt from April 1987 to April 1999 was summarized. ResultsThere was no death in 54 patients receiving selective operation;of 2 cases receiving emergency operation, one died. Among 49 followed-up cases, there was one rebleeding,2 hepatic encephalopathy, and one died of liver failure 4 years after opeation. The mean portal pressure before and after operation was(3.42±0.46) kPa and (2.50±0.35) kPa, respectively. ConclusionCombined portoazygons devascularization and shunt not only decreases portal pressure but preserve hepatic blood flow to some extent.

Since the release rate of protein in hydrogels is directly dependent upon the size of the protein and the hydrogel, how to deliver low molecular weight protein for prolonged periods has always been a problem. In this article, we present a usage of self-assembling peptide (P3) with the RGD epitope on its N terminus. The concentration of the released insulin-like growth factor 1 (IGF-1) was determined by UV-vis spectroscopy and the release kinetics suggested a notable reduction of the IGF-1 release rate. Cell entrapment experiments revealed that IGF-1 delivery by biotinylated nanofibers could promote the proliferation of the mouse chondrogenic ATDC5 cells when compared with cells embedded within nanofibers with untethered IGF-1.

Objective:To investigate the endothelialization and intermediate and long-term patency rate of prostheses seeded by CD34+ stem cells.Methods:sixteen crossbred dogs were randomized into 2 groups.Prostheses covered with ePTFE or Dacron were implanted into the abdominal aorta artery(AAA) and inferior vena cava(IVC).Twelve dogs were implanted by prostheses seeded by CD34+ stem cells,4 dogs were implanted by autogenous blood only as control.The prostheses were explanted at thirty or sixty or one hundred days.Light and electron microscopy were applied to examine endothelialization of prostheses.CD34 factor stain was used to identify endothelial cells.Results:All venous prostheses implanted by autogenous blood were blocked.Others were patent.Confluent endothelial cells appeared on the neointima of seeded prostheses.There were no endothelial cells in the no-implanted prostheses.Conclusion:Endothelialization and higher patency rate might be achieved in the prostheses covered with ePTFE or Dacron that were implanted by CD34+ stem cells.

OBJECTIVE To explore the sterilizing effect of low-temperature vacuum formaldehyde.METHODS The test group used the own-produced 140 L low-temperature vacuum formaldehyde sterilizer for sterilization;and the control group used "Xinhua" hydrogen peroxide plasma sterilizer.Sterilization effect of the two groups was monitored by biological indicator.RESULTS After 50 sterilization procedures run in test group,the biological indicators the bacterial were all killed,the qualification rate of sterilization was 100%.But after 30 sterilization procedures run in control group,only 8 procedures were qualified,the qualification rate of sterilization was 26%.The sterilizing effect of the two groups was significantly different(P

Objective To investigate the effect and the mechanism of up-regulating histone acetylizad level with a selective inhibitor of HDACs-Valproate acid sodium (VPA) on breast cancer cell proliferation. Methods MCF-7 cells were cultured with 0.75-4.0 mmol/L valproic acid (VPA) for 24, 48, 72, 96 hours in vitro, the inhibiting rate was tested by MTT assay. Cell cycle was analyzed by flow eytome- try with PI assay, and the protein and mRNA expressions of Cyelin A, Cyclin DI, Cyclin E, P21Waf/cipl of MCF-7 cells after 1.5, 3.0 mmol/ L VPA treated were analyzed by indirect immunofluorescence technique and RT-PCR respectively. Results After cultured with 0.75 -4.0 mmol/L valproic acid (VPA) for 24, 48, 72, 96 hours, the inhibiting rate of experimental groups increased significantly(P<0.01) and a dose and acting time dependent manner was found. As to cell cycle, the percentages of GI, S, M phrase in control groups remained the same. Contrary to control groups, 0. 75 -4.0 mmo]/L VPA induced a significant arrest in G1 phrase ( P<0.01), and a total of 55.4% -82.8% G1 phrase ratio were found. P21Waf/cipl was up-regulated both at the mRNA and protein level while Cyclin D1 was down-regulated ( P<0.001). Conversely, neither mRNA nor protein expression of Cyclin A, Cyclin E showed difference ( P>0.05). Conclusions Up- regulating histone acetylizad level can inhibit breast cancer cell proliferation, induce cell cycle arrest in G1 phrase. VPA, as a I class of histone deaeetylase inhibitor, can be used as an option in the treatment of breast cancer. The mechanism may include up-regulating P21Waf/cipl mRNA and protein expression and down-regulating Cyclin D1 mRNA and protein expression.

Objective To investigate the relationship between metabolic syndrome (MS) and education level in Su-Xi-Chang area to provide evidence for healthcare policy making. Methods A clustered sampling of 6798 subjects from Su-Xi-Chang areas of Jiangsu Province was included. Questionnaires and physical examinations were completed to collect clinical data. Logistic regression was used to analyze weather education level could be an independent risk factor of MS. Results Significant differences were found in waist circumstance (WC) ,systolic blood pressure (SBP) and fasting blood glucose (FBG) among participants with different education level. Significant differences were also existed in triglyceride and diastolic blood pressure (DBP) between subjects with higher and lower education level ( P＜0. 05 ). In single-factor or multivariate analysis, education level was negatively correlated with the prevalence of MS (P＜0. 05 ). Conclusions Education level may be an independent risk factor of MS. People with low and moderate education level have higher risk of MS. Therefore,it is recommended that health-related information should become an integral part of the compulsory education system.

Objective To investigate the relationship between metabolic syndrome (MS) and diet style in the elderly. Methods The 781 old people were consecutively selected. Related data were collected by means of questionnaires and physical examinations. And logistic regression was performed to analyze if moderate and high fat diet were risk factors of MS. Results The total prevalence rate of MS in old people was 40. 7%, with 36.7% in old males and 55.4% in old females,and the prevalence rate of MS was higher in old women than in old men (P=0. 000). The significant differences in waist circumferences among three groups of low, moderate and high-fat diet [(86.0±9.3) cm vs. (88.8±8.5) cm vs. (90. 0±7.9) cm, respectively (all P＜0.05)]were found. Fasting blood glucose showed a significant difference between two groups of low and high-fat diet, with the results of (5.78 ± 0.98) mmol/L and (6.27 ± 1.80) mmol/L, respectively ( P＜0. 05 ). The logistic regression analysis showed that odds ratio for people with moderate and high-fat diets were 1. 541 ( 1. 092-2. 174) and 2. 293 ( 1. 317-3. 994), respectively (P＜0.05), which indicated that moderate and high-fat diet was independent risk factors for MS in old people. Conclusions Both moderate and high-fat diets are risk factors of MS in old population, low fat diet with food balance is recommended to old population in order to decrease the prevalence of MS.
