Thirty cases of rheumatoid arthritis were treated by the needle-warming method on bilateral Shenshu (BL 23), Zusanli (ST 36) and Quchi (LI 11), in combination with oral administration of Chinese herbal drugs, and 30 cases were treated by routine western medications for comparison.After treatment for three months, the effective rate was respectively 86.7% and 60.0% in the two groups and the difference of the therapeutic effect was statistically significant (P＜0.05).

BACKGROUND:Critical limb ischemia is difficult to be treated among the peripheral arterial occlusive diseases, and the application of transplanting autologous stem cells can bring a hope for the treatment of this disease.
OBJECTIVE: To review the autologous stem cells transplantation in the treatment of critical limb ischemia at present, and to study the mechanism and the existing problems.
METHODS:A computer retrieval of PubMed database, Wanfang database, and CNKI database was conducted to search the related articles with the keywords of“stem cell, transplant, critical limb ischemia”in English and Chinese. Final y, 47 articles were included in final analysis according to the inclusion criteria.
RESULTS AND CONCLUSION:Autologous stem cells transplantation for treatment of lower extremity ischemic disease is a latest and significantly effective treatment, but the mechanism is unclear and stil needs further study.

Objective To investigated the neuroprotective effect of PTEN inhibitor BPV on cerebral ischemia-reperfusion injury in rats and its mechanism. Methods Male Sprague-Dawley rats were used to induce a reperfusion model of middle cerebral artery occlusion for 1 h. During the reperfusion, the BPV solution (0. 2 mg/kg daily) or the equal volume of saline was injected intraperitonealy immediately. The neurological deficit scores were conducted at day 1, 3,5, and 7 after ischemia-reperfusion. At day 4, triphenyl tetrazolium chloride staining was used to assess cerebral infarction volume. Enzyme-linked immunosorbent assay was used to detect the levels of interleukin 10 (IL-10) and tumor necrosis factor α(TNF-α) in cortical ischemic border zones. Real-time quantitative polymerase chain reaction was used to detect the expression level of PTEN mRNA. Western blotting was used to detect the expression levels of PI3K, Akt, and p-GSK-3β. At day 7, Bielschowsky silver staining was used to detect the axonal distribution in the ischemic border zone of the striatum. Immunohistochemical staining was used to detect the expression of myelin basic protein (MBP). Results At day 4 after ischemia-reperfusion, the infarct volume (32. 27% ± 1. 71% vs. 45. 49% ± 2. 12% ; P < 0. 001), TNF-α concentration in the cortical ischemic border zones (134. 17 ± 10. 38 pg/ml vs. 264. 17 ± 24. 84 pg/ml; P < ), and PTEN mRNA level (1. 19 ± 0. 08 vs. 2. 50 ± 0. 06; P < 0. 001) in the rats of the BPV group were al significantly lower than those of the normal saline group. The IL-10 concentration (186. 83 ± 10. 83 pg/ml vs. 147. 83 ± 11. 62 pg/ml; P < 0. 001), and the expression levels of PI3K (0. 43 ± 0. 08 vs. 0. 26 ± 0. 06; P = 0. 004), Akt (0. 52 ± 0. 05 vs. 0. 40 ± 0. 04;P = 0. 001), and p-GSK-3β (0. 75 ± 0. 08 vs. 0. 38 ± 0. 06; P < 0. 001) were al significantly higher than those of the normal saline group. At day 7 after ischemia-reperfusion, the neurological deficit score (4. 83 ± 0. 41 vs. 6. 33 ± 0. 52; P < 0. 001) in the rats of the BPV group was significantly lower than that of the normal saline group. The axon densities in the ischemic border zones (35. 51% ± 2. 45% vs. 25. 31% ± 2. 79% ; P < 0. 001) and the expression level of MBP (32. 56% ± 3. 46% vs. 27. 81% ± 4. 18% ; P = 0. 037) were significantly higher than those of the normal saline group. Conclusions BPV has neuroprotective effect for cerebral ischemia-reperfusion injury in rats. Its mechanism may be associated with the up-regulation of PTEN downstream proteins PI3K, Akt and p-GSK-3β expression to regulate inflammatory mediators and reduce the inflammatory response.

Reovirus,a kind of oncolytic viruses, is seldom pathogenic, but is selectively able to replicate in cancer cells through activation of Ras signaling. Pre-clinical studies have demonstrated that treatment with reovirus is associated with significant anticancer activity across a range of tumor types. Further clinical evaluation of reovirus therapy has shown that it is well tolerated when administered locally or systemically. Encouraging anticancer efficacy has been observed with single-agent treatment and in combination with chemotherapy and radiotherapy. High safety and promising efficacy of reovirus has raised hopes that it will become a new anticancqt agent.

Objective To discuss the indication, technique, effect, and safety of endoscopic treatment of SMT in gastrointestinal tract. Methods Endoscopic therapy was performed in 94 patients with gastrointestinal diagnosed by endoscopy. 22 cases underwent EMR; 61 cases were treated with ESD; MBM was exercised on 7 cases; and nylon endoloop ligature were carried out on 4 cases. Results Complete resection was achieved on 86 cases, and 1 case was excised partially. 1 patient with SMT was transferred to open surgery. Lumps of 4 SMT cases treated by nylon endoloop ligature were found disappeared at subsequent visit after a month. All patients were followed up for one year, and no recurrence was found. Conclusions Gastrointestinal SMT can be completely resected by EMR, ESD and MBM. Nylon endoloop ligature can be used for the treatment of SMT in position difficult to deal with. Endoscopic therapy is relatively safe, effective, and minimal invasion for SMT.

Objective To investigate the therapeutic effect of sodium aescinate (SA) on severe acute pancreatitis (SAP) in rats.Methods SAP model was induced by intraductal administration of 5％ taurocholic acid sodium salt.SD rats were then randomly divided into 3 groups (n =16),namely sham,model and SA group (5 mg/kg).Drugs or saline(10 ml/kg) were administered via caudal vein 30 min post-operation.The serum amylase was measured with spectrophotometer and pancreatic histological changes were observed under microscope 6 h and 12 h post-operation,respectiveiy.Results Pancreatic histological grades in the model group were (9.42 ± 1.06) and (18.30± 2.18) 6 h and 12 h post-operation,respectively,which showed significant differences (P＜0.01) compared with the sham group [(0.55 ±0.20) and 0,respectively].SA evidently reduced the severity of pancreatic pathology and improved the tissue inflammation in rats with SAP.Pancreatic histological grades were (7.85±1.33) and (12.75±1.69)in the SA group 6 h and 12 h post-operation,respectively,which had significant differences compared with the model group (P＜0.05).Serum amylase levels in model group were (2612 ± 59) U/L and(3004±687)U/L6 h and 12 h post-operation,respectively,which showed significant differences (P ＜ 0.01) compared with the sham group [(928 ± 271) and (890± 295) U/L,respectively].Serum amylase levels were reduced to (1790± 336) U/L and (2093 ± 298) U/L in the SA group 6 h and 12 h post-operation,respectively.SA markedly inhibited the level of serum amylase compared to the model group (P＜0.01).Conclusion SA could protect rats with SAP effectively.

Objective To investigate the effect of calcium channel antagonist verapamil upon coronary vessel disease of allograft heart transplant rat model.Methods 160 SD rats weighing 220 to 300 g were randomly allocated to control group (group 1, n=40) and experiment groups (group 2, n=40; group 3, n=40, group 4, n=40). The hearts of all donor rats were implanted into the recipient rats. From the day after operation, the rats in each group were fed routinely and injected intraperitoneally (ip) with Cyclosporin (5 mg?kg~ -1?d~ -1 for 10 days). In experiment groups, the rats were individually injected (ip) with verapamil by 0.1 mg/kg,0.5 mg/kg,1.0 mg/kg twice every day for 3 months, but the rats in control group were not subjected to injection. At 60th and 90th day after grafting, 10 of each group were selected randomly and transplanted hearts were cut. The specimens were stained with HE and histochemistry.Result The degree of intimal hyperplasia in the control group was more severe than in the experiment groups.Conclusion Calcium channel antagonist verapamil can effectively inhibit the intimal hyperplasia of coronary arteries in heart transplant model.

[Objective]To study the evaluation method for total ankle replacement.[Method]According to anterior-posterior and lateral Xray films of ankle joint pre-and postoperatively,the level of osteotomy and method of bone grafting were confirmed and the correct position of total ankle replacement and its complication were evaluated.Forty-six cases of total ankle replacement were followed up 2~8 years and 4 months with average 5 years and 5 months.With author's radiographic evaluation method and Ko-foed's system,results of ankle function were evaluated.[Result]The foot dorsiflexion was 6?~16? and plantoflexion 8?~28?,movement range of foot dorsiflexion and plantoflexion was 14?~38?(average 21.4?).The function results showed excellent(85~100) in 32 ankles,good(75~84) in 9,and poor(60~74) in 2,no failure case.The complication included necrosis of incision border skin of 3 ankles and intraoperative fractures of both melleola of one ankle;no foot inversion and eversion,no radiographic loosenning were seen.[Conclusion]Radiological evaluation is a critical and useful measure to enhance the quality and function of total ankle replacement,to prevent and to early find its complications.

Objective To evaluate a new surgical approach for the treatment of carcinoma of the gastric cardia. Methods The GI stapler was used to perform intramediastinal esophagogastrostomy for cardial carcinoma in 89 cases and esophago-jejunostomy in 16 cases undergoing total gastrectomy by the transabdominal approach with incising the crus dextrum of the diaphragm. Results The average length resected of the lower part of the esophagus was over 7 cm. Intramediastinal lymph node metastasis was found by pathology in 209% (22/105).There was no operative mortality and the morbidity rate was 476%, 5 year survival rate was 39%. Conclusions The technique enables lymphadenectomy within the lower mediastinum and a sufficiently long enough resection of the esophagus. Transabdominal incision of the crus dextrum of the diaphragm makes a clear operative field for the purpose of radical operation for carcinoma of the gastric cardia. The anastomosis by GI stapler effectively prevents anastomotic leakage.This procedure is indicated for cardial carcinoma cases in which the esophageal involvement is within 2 cm.
