Objective To evaluate the timing of postoperative parenteral nutrition support for gastrointestinal tumor patients with a definite nutritional risk.Methods Using a randomized control clinical research methods,80 gastrointestinal cancer patients were randomly divided into study group (40 cases) and control group (40 cases).In the study group parenteral nutrition support started on postoperative day 2,while in the control group it started on postoperative day 1.Flatus passing,the rate of infectious complications,the rate of systemic inflammatory response syndrome,postoperative nutrition support related expenses,and the duration of postoperative hospital stay were recorded.Results There was no significant differences between the two groups (P ＞ 0.05) in age,sex,body mass index,use of glutamine,disease and type of surgery.Compared with the control group,patients in the study group had earlier postoperative flatus passing [(3.33± 1.10) d vs.(4.03 ± 1.51) d,P =0.020],less systemic inflammation response syndrome (8/40 vs.17/40,P =0.030),shorter postoperative hospital stay [(3.33±1.10) d vs.(4.03±1.51) d,P=0.020] and lower nutrition support costs [(2144.49 ±1210.96) RMB vs.(2915.99 ± 1615.68) RMB,P =0.018].There was no significant difference in postoperative nutrition index,peristalsis recovery time and infectious complications between the two groups (all P ＞ 0.05).Conclusions In patients undergoing surgery for GI tumors,parenteral nutrition support started on post-op day 2 promotes the recovery of gastrointestinal function,while decreasing medical cost.

Objective:To observe the effects of AFP gene silencing by siRNA on the Survivin mRNA of hepatocellular carcino-ma cell line HepG2. Methods:AFP gene expression was downregulated in HepG2 cell by RNAi, and the AFP content in the superna-tant was detected by ELISA. Survivin mRNA level was tested by RT-PCR. MTT was applied to evaluate cell proliferation. Flow cytom-etry was employed to observe cell apoptosis. Results:At 48 h after transfection, AFP expression was almost completely inhibited, cell proliferation activity was decreased by 43.1%, cell apoptosis rate was increased by 24.3%, and the Survivin mRNA expression was re-duced to 22.0%in the experimental group. No evident changes were observed in negative control and blank groups. Conclusion:AFP gene silenced by RNAi induces growth inhibition and apoptosis promotion of hepatocellular carcinoma cell line HepG2. This gene may be associated with the suppression of Survivin mRNA.

Objective To further investigate clinical manifestations and management for thallium poisoning. Methods Clinical data of 6 patients who were hospitalized in Union Hospital of Tongji Medical College in May 2008 with diagnosis of acute or chronic thallium poisoning,were retrospectively analyzed.Results Six patients (4 male and 2 female) ,aged from 12 to 50,came from one family (two sisters with their husbands and sons). Five of them (3 acute and 2 chronic,for the second time in half a year,thallium poisoning) initiated with peripheral neuritis,represented with severe burning pain,numbness,paresthesia in the lower limbs,accompanied with or without gastrointestinal symptoms. A 12 year-old boy with obviously elevated urinary thallium concentration was asymptomatic. Blood and urinary thallium concentrations of the patients were determined by atomic absorption spectrophotometry and were all significantly elevated.Treatment was initiated using potassium supplementation,diuresis,oral laxatives,Prussian blue and intramuscular injection of dimercaptopropansulfonate sodium.Meanwhile two of them were treated with hemoperfusion. Finally,two of them recovered,another two were transferred to a specialized hospital for continuous treatment,and the rest two deteriorated rapidly with occurrence of unconsciousness and died of multiple organ failure. Conclusions The main clinical manifestations of thallium poisoning are multiple peripheral neuritis,gastrointestinal symptoms and dermatological changes. In order to avoid missed diagnosis and misdiagnosis,a high suspicion should be arose for thallium poisoning when a patient suffering from the above symptoms.Prussian blue was considered traditionally as an effective therapeutic strategy for the condition,and hemoperfusion may be a more effective treatment for acute thallium poisoning.

OBJECTIVE:To compare the efficacy,safety,vascular endothelial growth factor(VEGF)and matrix metallopro-teinase-2 (MMP-2) of docetaxel combined with carboplatin and paclitaxel combined with cisplatin (DDP) in the treatment of ad-vanced ovarian cancer. METHODS:120 patients with advanced ovarian cancer were randomly divided into docetaxel combined with carboplatin group(60 cases)and paclitaxel combined with DDP group(60 cases). Docetaxel combined with carboplatin group received 70 mg/m2 Docetaxel injection,intravenous infusion of 1 h,d1;50 mg/m2 carboplatin injection,intravenous infusion of 1 h,d2. Paclitaxel combined with DDP group received 135 mg/m2 Paclitaxel injection,intravenous infusion of 24 h,d1;30 mg/m2 DDP for injection,intravenous infusion,d3;60 mg/m2 Paclitaxel injection (a maximum of 2.0 m2) by intraperitoneal infusion,d8. 3-week was regarded as 1 treatment course,and it lasted 6 courses. Clinical efficacy,VEGF,MMP-2,progression-free survival, overall survival before and after treatment,mortality rate within 2 years of treatment and the incidence of adverse reactions in 2 groups were compared. RESULTS:There were no significant differences in the objective response rate,disease control rate,mortal-ity rate,incidence of adverse reactions between 2 groups(P>0.05). The progression-free survival in docetaxel combined with car-boplatin group was significantly longer than paclitaxel combined with DDP group,the difference was statistically significant (P<0.05). Before treatment,there were no significant differences in VEGF and MMP-2 level between 2 groups(P>0.05). After treat-ment,VEGF and MMP-2 level in 2 groups were significantly lower than before,and VEGF at different time points and MMP-2 level after 4 weeks,8 weeks and 12 weeks of treatment in docetaxel combined with carboplatin group were lower than paclitaxel combined with DDP group,the differences were statistically significant(P<0.05). CONCLUSIONS:Docetaxel combined with car-boplatin and paclitaxel combined with DDP shows similar efficacy and safety in the treatment of advanced ovarian cancer,but docetaxel carboplatin combined with is superior to paclitaxel combined with DDP in reducing VEGF and MMP-2 and improving pro-gression-free survival.

Objective:To observe the clinical efficacy of acupuncture at abdomen acupoints plus tuina for lumbar intervertebral disc herniation (LIDH).Methods:A total of 70 patients with LIDH were randomized into an observation group and a control group,with 35 cases in each group.The observation group was treated with acupuncture at abdomen acupoints plus tuina,while the control group was treated only with tuina treatment.The clinical efficacy was observed after one course of treatment.Results:The cure rate and the total effective rate of the observation group were 83.3％ and 96.7％,respectively.The cure rate and the total effective rate of the control group were 39.4％ and 78.8％,respectively.There were significant differences in the cured rate and the total effective rate between the two groups (both P＜0.05).There was no significant difference in Japanese Orthopedic Association (JOA) score between the two groups before treatment (P＞0.05).After treatment,the JOA scores of both groups increased significantly,and the intra-group differences were statistically significant (both P＜0.05);the JOA score of the observation group was significantly higher than that of the control group (P＜0.05).Conclusion:Acupuncture at abdomen acupoints plus tuina has a better therapeutic effect than tuina alone in the treatment of LIDH.

Objective To transplant the umbilical cord mesenchymal stem cells(UCMSCs) derived from human umbilical cord into cisterna magna of hypoxic-ischemic encephalopathy(HIE) rat model,and to observe their survival,proliferation and differentiation in the rat brain.Methods UCMSCs were isolated from human umbilical cord of babies delivered after full-term normal cesarean section,and labeled by bromodeoxyuridine(BrdU).Pregnant rats were randomly divided into experimental group(n=6) and control group(n=1).HIE models were built by ligating both sides of the uterine arteries of full-pregnant rats(21 days) in experimental group rats for 15 minutes.The neonatal rats in experimental group were divided into stem cells group(n=24) and PBS group(n=19) at random.The labeled UCMSCs were injected into cisterna magna of the rats in stem cells group,while PBS was injected into the rats of PBS group.In 1,2,3 and 4 weeks after transplantation,the brain tissue section slides were immunohistochemically stained with antibodies against BrdU,Nestin,neuron specific enolase(NSE) and glial fibrillary acidic protein(GFAP),and thionin.Control group with normal delivery was tested as concurrent control.Results At 1 week after transplantation,BrdU,Nestin,NSE and GFAP positive cells were found in the hippocampal dentate gyrus of the rats in stem cells group rats.The number of BrdU-positive and Nestin-positive cells increased(Pa0.05).The NSE-positive and GFAP-positive cells gradually increased from 1-4 weeks post transplantation and comparisons between groups had statistical significance(Pa

Objective: To observe the clinical efficacy of Tuina (Chinese therapeutic massage) plus needling the distal acupoints along the pathway of meridians for shoulder periarthritis (SP). Methods: A total of 70 patients with SP were divided into an observation group and a control group using the random number table method, with 35 cases in each group. The patients in the observation group were treated by Tuina combined with needling distal acupoints along the pathway of meridians, while those in the control group only received the same Tuina treatment as in the observation group. The visual analog scale (VAS) and shoulder joint function were scored before and after treatment, and the efficacy after treatment was evaluated. Results: After three courses of treatment, the total effective rate of the observation group was 94.3％, while the total effective rate of the control group was 80.0％, showing a statistical difference (P<0.05). After treatment, the VAS scores of the two groups were significantly lower than the baseline scores (P<0.01), and the VAS score of the observation group was lower than that of the control group (P<0.01). After treatment, the total scores of internal rotation, external rotation, back touching, ear touching and motion function in the two groups were significantly higher than those before treatment (P<0.01), and the above five scores in the observation group were significantly higher than those in the control group (P<0.01). Conclusion: Tuina combined with needling the distal acupoints along the pathway of meridians is more effective than Tuina alone in treating SP. The combined therapy can relieve the pain and improve joint function more effectively.
