Objective To evaluate the clinical effect of levocarnitine in the treatment of continuous blood purification and its effect on matrix metalloproteinase-2(MMP-2),interleukin-18(IL-18)and heart function.Methods 118 patients with continuous blood purification were randomly divided into the control group(n=59)and treatment group group(n=59).Two groups were treated with hemodialysis treatment.Control group was given folic acid,vitamin B and alpha keto acid,treatment group intravenous given levocarnitine injection 20mg/kg+0.9％NaCl 20mL on the basis of control group.A cycle of treatment was 28 days,and treated for 3 cycles.Serum levels of MMP-2 and IL-18,heart function,clinical effect and adverse drug reaction were compared between the two groups.Results After treatment,the total effective rate in control group was 84.74％,lower than 94.92％in treatment group(P<0.05).After treatment,serum MMP-2,IL-18,left atrial diameter(LAD),left ventricular end diastolic diameter(LVDd),left ventricular posterior wall thickness(LVPWT),ventricular septal thickness(IVST),left ventricular volume index(LVMI)in two groups were lower than pre-treatment(P<0.05),and the indexes in treatment group were more lower than control group(P<0.05).The E/A and left ventricular ejection fraction(LVEF)in two groups were all increased after treatment,and those in treatment group were higher than control group,the differences were significant(P<0.05).There was no significant in the incidence rate of adverse drug reactions between two groups.Conclusion Levocarnitine in the treatment of continuous blood purification was effective,and significantly reduce the serum MMP-2,IL-18 level and improve the heart function.

Objective To compare the clinical efficiency between laparoscopic enterodialysis and open enterodialysis. Methods Clinical data of 25 cases of adhesive intestinal obstruction treated by laparoscopic enterodialysis (Laparoscopic Group) from December 1999 to December 2002 were retrospectively reviewed and compared with clinical records of 23 cases receiving open enterodialysis (Open Group) in the same period. The operating time, intra-operative blood loss, incidence of complications, postoperative recovery time of bowel movement and length of hospital stay of the two groups were compared, respectively. Results In the Laparoscopic Group operation was successfully accomplished in 23 cases while a conversion to open surgery was required in 2 cases. Of the Laparoscopic Group and the Open Group, the operation time was (58.3?8.1) min and (84.0?7.5) min (t=11.383, P=0.000), respectively; the intra-operative blood loss was (31.4?5.1) ml and (192.6?26.4) ml (t=29.995, P=0.000), respectively; the postoperative hospital stay was (4.1?1.4) days and (9.7?2.0) days (t=11.413, P=0.000), respectively; the postoperative recovery time of bowel function was (19.6?2.2) hours and (49.0?8.8) hours (t=16.207, P=0.000), respectively and the postoperative complications were seen in 1 case and 9 cases (?2=6.960, P=0.008), respectively. Conclusions Compared with open enterodialysis, laparoscopic enterodialysis has advantages of short operation time, less blood loss, rapid recovery and fewer complications.

Desmoid tumor(DT),a rare benign tumor sometimes with local invasion,is more frequently seen in patients with familial adenomatous polyposis(FAP) than in the general public,which might be associated with surgical trauma,genetic predisposition and hormonal factors.Fifty percent of FAP-associated DTs are intra-abdominal,usually present as non-tender,slowly growing masses.The symptoms include abdominal pain,vomiting and diarrhea,etc.Mesenteric DT can cause obstruction and ischemia of intestine,hydronephrosis and fistula.Diagnosis can be made through biopsy or CT scanning.Surgery should be considered for the abdominal wall DTs and medicine is the first choice for mesenteric DTs.Surgery should be chosen with caution.

96 anterior teeth with different degree of caries in 80 patients were randomly divided into 2 groups(n =48 teeth,40 patients). In the experimental group the teeth were repair with nanometer resin filling,in the control group with ceramic crown.In 0.5 to 1 year follow-up,the satisfaction rate and the clinical success rate were similar in the 2 groups(P >0.05).Application of nano resin aesthetic restoration can lower tooth injury,postoperative complications and the cost.

BACKGROUND: It has been suggested that amniotic epithelial cells (AECs) express almost all of the markers of neural cell and secret a lot of neurotrophic factors and neurotransmitters. If AECs could substitute neural cells, its neurotrophic effect will bring promising prospect in treating neuron injuries and degenerative neural disease.OBJECTIVE: To detect specific proteins of neural cells in rat's cultured AECs.DESIGN: Repeated measurement design.SETTING: Second Clinical Medical College , Jilin University; Department of Histology & Embryology, School of Basic Medical Science, Jilin University.MATERIALS: This experiment was conducted at the Department of Histology & Embryology, School of Basic Medical Science, Jilin University from October 2004 to October 2005. The rat amniotic epithelial tissue was mechanically peeled from an embryonic 12 to 14days Wistar rats. Mouse anti Nestin was purchased from Chemicon Co.,and anti-ChAT rabbit anti-NSE and anti-NT-3 antibodies from Wuhan Boshide Company. Mouse anti-Musashi antibody was donated by Pro.Okano.METHODS: AECs were dissociated and purified from the amnion of pregnancy 12-14 day rats. AECs were treated with trypsin for 5 minutes,then cultured in DMEM/F12 medium at a humidified atmosphere of 0.05 volume fraction of CO2 in air at 37 ℃. Cells were inoculated at a concentration of 5×109 cells/L in culture flask. After 3 days, cells were inoculated onto poly-lysine-treated 35 mm culture Petri dish at a density of 1 × 108 cells/L for immunocytochemically staining. The cells were fixed with 40 g/L paraformaldehyde for 20 minutes. Immunocytochemical staining method was used to detect the expression of microtubule-associated protein-2 (MAP-2),neuron specific enolase(NSE), glial fibrillary acidic protein (GFAP) and choline acetyl transferase(ChAT).MAIN OUTCOME MEASURES: ① Morphological observation of rat'AECs at different culture time. ② Expression of specific protein of neural cells in rat' cultured AECs.RESULTS: ① After cultured for 24 hours, the AECs were flat and presented fibroblast-like morphology. 3 to 5 days later, cell bodies were well stacked; AECs had a big and round nucleus and were connected with each other by flourishing dendrites. ② Immunocytochemical staining results after culture for 4 days showed that AECs expressed Nestin, ChAT,NSE, Musashi, MAP-2, GFAP.CONCLUSION: AECs are homologous to neural cells in morphology, and it may be a new cell source to treat nervous system disease.

Peripheral blood mononuclear cells (PBMNC) isolated from patients with acute leukemia (AL) and from normal controls were cultured in medium containing 1000 units/ml of recombinant interleukin 2 (IL-2). Marked LAK activity was induced on the third culture day in the normal controls,, with the highest cytotoxicity appearing between day 3 and 5 whereas induction of LAK activity in the AL patients began on the 5th day of culture, with the peak level appearing at day 15, showing that the peak of LAK activity was significantly delayed in AL. LAK cells surface phenotyping tests showed that CD8+ and CD16+ positive cells began to increase significantly from day 5 and reached the highest level at week 3, whereas CD4+ subclass began to decrease on day 5 and dropped to the nadir at week 3. The proportion of CD8+ and CD16+ cells were positively cor related with LAK activity, but, that of the CD4+ cell was inversely related with the LAK activity.

Abstract: This study is to elucidate the metabolic pathway of 1,2-[bis (1,2-benzisoselenazolone-3 (2H)-ketone)]-ethane (BBSKE) in rats. Rats were administrated with a single dose of BBSKE 200 mg x kg(-1). The metabolites in rat urine, feces, bile and plasma were identified by LC-MSn analysis. The characterization of fragment ions from LC-MSn chromatography and mass spectrometry was applied to the investigation of structures of metabolites. Three phase I metabolites were detected in rat urine and feces. Two of them were also found in plasma and one existed in bile. These products were derived from oxidized, methylated and S-methylated BBSKE, separately. One phase II glucuronide of BBSKE was also found in bile. Therefore, it is possible that BBSKE was metabolized by oxidization, methylation and glucuronidation.

Objective To investigate the effect of percutaneous transluminal angioplasty(PTA) by minor-caliber and long balloon on diabetic patients with below-knee artery. Methods 16 consecutive DM patients(21 limbs)were treated with PTA by minor-caliber and long balloon and followed 7 months(1 ～22 months). The success rate,complication,clinical effects and the changes of ABI were investigated and analyzed. Results The technical success rate is 90.5% (19/21) ,no serious complication occurred. The clinical symptoms of all patients improved after successful PTA. The median ABI marginally increased from the baseline value of (0.31 ±0. 15) to (0.57 ±0.23) after intervention,the difference is significant (P ＜ 0.05). Post-operative pain in patients with rest pain disappeared 9 (60.0%), relieved 4 (26.7%), reduce 2 (13.3 %). Ulcer healing in patients with foot gangrene 4 (66.7 %), Ulcer area was significantly reduced 1 (16.7%), high amputation 1 (16.7%). Postoperative follow-up, two limbs reoperation because of increased symptoms. Conclusion The treatment of percutaneous transluminal angioplasty by minorcaliber and long balloon was effective on diabetic patients with below-knee arterial disease.

Hyperuricemia and metabolic syndrome were studied in 17 762 subjects of Tianjin Municipality from July 2007 to July 2009. The overall prevalence rate of hyperuricemia was 12. 16% (2160cases) , the rate in males was significantly higher than that in females (15. 71% vs. 6. 51% , P <0. 01).The overall prevalence rate of metabolic syndrome was 25. 56% (4540 cases) , the rate in males was also higher than that in females (28. 17% vs. 21. 40% , P <0. 01). Binary logistic regression analysis disclosed that females with high uric acid were twice likely to suffer from metabolic syndrome than males; and female ≤ 44 years with hyperuricemia had the highest odd ratio for metabolic syndrome.

Objective To discuss compatibility regularity of Banxia Xiexin Decoction adjusting gastric mobility. Methods Ninty healthy SD male rats were divided into normal group (10 rats) and model group (80 rats). Rat models of electrogastric dysrhythmias were established. After the evaluation of gastric electrophysiology, Banxia Xiexin Decoction were divided into Xinkai, Kujiang, Ganbu, Xinkaikujiang, Xinkaiganbu, and Kujiangganbu groups according to the compatibility regularity of Banxia Xiexin Decoction, 10 rats for each group. Rats in each medication administration group received gavage with same concentration but different volume for 4 weeks. Each group was analyzed for gastric electrical parameters after administration. The expressions of Cx43 and Cx43 mRNA in the gastric tissue of rats in each group were analyzed by immunohistochemistry and real-time fluorescent quantitative PCR. Results Compare with the normal group, the expressions of Cx43 and Cx43 mRNA in the gastric tissue of rats increased significantly in the model group. Compared with the model group, variable coefficient of electrogastric slow wave frequency in all medication administration groups decreased obviously. Banxia Xiexin Decoction and its components had decreased the expression of Cx43 and Cx43 mRNA to some extent, among which Xinkaiganbu group had best effects. Conclusion The mechanism of Banxia Xiexin Decoction adjusting gastric motility maybe related to its function of decreasing the expressions of Cx43 and Cx43 mRNA, as to adjust disordered electrogastric rhythm.
