OBJECTIVETo compare differences of clinical therapeutic effect of heat-sensitive moxibustion with different doses for irritable bowel syndrome (IBS).

METHODSSixty cases of IBS were randomly divided into a saturated-dose group (30 cases) and a traditional-dose group (30 cases). Heat-sensitive moxibustion was applied in both groups. The acupoints that had the strongest heat-sensitive feeling were selected and treated by warm and suspended moxibustion with moxa stick. Disappearance of heat-sensitive feeling was taken as the sign of treatment time in the saturated-dose group, while the traditional-dose group was treated for 15 min each time. The treatment in both groups was given twice a day for first 5 days, and from the sixth day it was given once a day for continuous 25 times, totally 30 days. Clinical symptom scores and therapeutic effect before and after treatment in two groups were observed.

RESULTSAfter the treatment, the cured and markedly effective rate was 75.0% (21/28) in the saturated-dose group, which was inferior to 44.4% (12/27) in the traditional-dose group (P < 0.05). The clinical symptom scores, including diarrhea, abdominal distension and pain, were obviously reduced in two groups compared with those before the treatment (all P < 0.05). Compared with the traditional-dose group, the symptom scores of diarrhea and abdominal distension in the saturated-dose group were obviously decreased (0.87 +/- 0.13 vs 1.27 +/- 0.21, P < 0.01; 1.12 +/- 0.41 vs 1.32 +/- 0.26, P < 0.05).

CONCLUSIONThe moxibustion featured with disappearance of heat-sensitive feeling and saturated dose has better therapeutic effect than that with traditional-dose for treatment of IBS. As individual dynamic amount of moxibustion, disappearance of heat-sensitive and quantitation varies from person to person, which is one of the key factors to obtain the best curative effect.

Lymphangiomas are made up of multiple lymphatic channels lined by benign-appearing endothelial cells. The lesions can occur anywhere in the body but most commonly affect head, neck and axilla. It rarely involves the gastrointestinal tract and particularly lymphangioma of the colon is very rare. Histologically, it is classified three types as simple or capillary, cavernous, and cystic. We experienced three cases of cavernous lymphangioma of the ascending colon. Case 1, 56-year-old male, had lymphangioma accompanied by ulcerating cancer of the cecum. Case 2, 51-year-old female, had lymphangioma of cecum. Case 3, 41-year-old male had lymphangioma at ileocecal valve. All cases could be diagnosed by colonoscopic snare polypectomy.

To establish HPLC specific chromatogram and its correlation with the protection effect of Shuanghuanglian on MDCK (Madin-Darby canine kidney) cell injury induced by influenza A virus( H1N1). Nine recipes of Shuanghuanglian based on the official prescription were prepared according to orthogonal test for HPLC analysis and MDCK cells protection experiment separately (cytopathic effect (CPE) method was used for observing the virus infectivity and MTT staining results were used as the determining indexes for drug concentration selection and analyzing cell viability). The results suggested that all the other Shuang-Huang-Lian recipes except recipe1 demonstrate protecting effect on MDCK cell injury induced by influenza A virus (P < 0.01, P < 0.001). Stepwise regression analysis was used for analyzing the relationships between HPLC fingerprint and the protecting effect of Shuanghuanglian on influenza A virus induced MDCK cell injury. Peak 2, 3, 6, 8 and 12 were found to be strongly related with anti-influenza A virus efficacy. Stepwise regression analysis of recipes data and efficacy data showed that Lonicerae Japonicae Flos and Forsythiae Fructus were positively associated with the protecting effect of cells injury. From HPLC fingerprints, we found that peak 2, 3, 12 were from Lonicerae Japonicae Flos and peak 6, 8 were from Forsythiae Fructus. Four peaks were identified through comparing the retention time between the standard and Shuanghuanglian recipes, and they were chlorogenicacid, cryptochlorogenic acid, forsythoside B and 3,4-dicaffeoylquinic acid respectively. Caffeic acid derivatives in Lonicerae Japonicae Flos and Forsythiae Fructus were found to be greatly correlated with anti-influenza A virus efficacy and maybe the substance basis of Shuanghuanglian.

Objective To explore the effect of transplantation of neural stem cells(NSCs)pretreated with brain-derived neurotrophic fac-tor(BDNF)on acute ischemic stroke in mice.Methods NSCs from a newborn(one day)C57BL/6 mouse were isolated and cultured in vi-tro.A total of 150 healthy C57BL/6 mice,ten-week-old,were randomly divided into five groups,that group A accepted sham operation,and groups B,C,D and E were subjected to focal ischemia by photothrombosis.Group D was transplanted NSCs 24 hours after ischemia,while group E transplanted NSCs pretreated with BDNF and group C accepted same volume of medium.All the groups were tested with rotarod test and grip strength one day before transplantation and three,seven,14,21 and 28 days after transplantation.The differentiation of NSCs in groups D and E were observed immunofluorescence staining of microtubule-associated protein-2(MAP-2)and glial fibrillary acidic pro-tein(GFAP).Results The time on rotarod arranged from more to less was groups E,D and B(P<0.05)three,seven,14,21 and 28 days after transplantation,as well as grip strength 14,21 and 28 days after transplantation(P<0.05).The Edu/GFAP positive cells and Edu/MAP-2 pos-itive cells were found in both groups D and E.Conclusion Transplanting NSCs can promote the behavioral recovery after ischemic stroke, and it is more effective as pretreated with BDNF.

Objective To evaluate the outcome of health education program on drowning prevention among primary and secondary school children in rural areas. Methods A township was selected and all the students from grade 3 to 5, grade 7 to 8, and grade 10 to 11 were selected to take part in the program. Twelve intervention measures on natural water safety and drowning prevention were carried out for one year. Information was collected using the same questionnaire before and after the intervention program. Results One year after the intervention was carried out, children's knowledge on drowning prevention improved significantly (13.21, 95% CI: 12.51-13.90) , and a positive effect was also noticed among boys (12.77, 95%CI: 11.77-13.77), girls (13.80, 95%CI: 12.82-14.78),and among primary school children (15.51,95%CI: 14.30-16.72), senior high school children (10.78,95%CI: 9.50-12.05) and junior high school children (12.77,95%CI: 11.84-13.71). Overall rates on risk behaviors dropped from 41.4% to 32.2% (by 22.2%) including 15.6% for boys, 35.2% for girls and 13.8%, 29.3%, 26.3% for primary school children, senior high school children, junior high school children, respectively. The incidence rates for non-fatal drowning decreased by 58.9% (from 5.6% to 2.3%). The person-times for treatment on sight, in emergency settings, in outpatient clinic or in the hospitals had a reduction from 399, 78, 36 to 175, 32, 14, respectively. Conclusion Health education program could improve children's perception on water safety, and reduce their risk behaviors as well as on the incidence of non-fatal drowning in the rural areas.

OBJECTIVE: To explore the operative strategy and clinical outcome of the thoracolumbar fracture dislocation. METHODS: Forty-two patients with the thoracolumbar fracture dislocation were treated with anterior approach (10 patients), posterior approach (28 patients), and anterior combined with posterior approach (4 patients) in order to construct the stabilities of the spine. The ASIA grades were used to evaluate the recovery of the neurological function, and the improvement of the kyphosis deformities was evaluated by the cobb's angle post-operation. RESULTS: All the patients had no complications of injury in the vascular and neurological system. The ASIA grades after the operation were superior to those of pre-operation, and the cobb's angle was rectified distinctly. CONCLUSION When appropriate operative strategies are adopted, thoracolumbar fracture dislocation can be treated with satisfactory outcome.

OBJECTIVETo evaluate the clinical and radiographic results of total lumbar disc replacement with SB Charité III prosthesis.

METHODSFrom Dec 1999 to Dec 2006, total lumbar disc replacement with SB Charité III prosthesis was performed in 65 patients affected with degenerative lumbar disc disorders. Among these patients, 48 (52 prosthesis) were followed up for more than two years (from 2.0 to 7.5 years). There were 22 males and 26 females with an average age of 43 years old (from 36 to 58 years). The diagnosis was lumbar disc herniation with low back pain in 34 patients, discogenic low back pain in 9 patients and failed lumbar disc surgery in 5 patients. All patients underwent standard anterior procedure under general anesthesia. One level replacement was done in 44 patients (L3,4 in 3, L4,5 in 23 and L5-S1 in 18), and two level procedures in 4 patients (L3,4/L4,5 in 1 and L4,5/L5-S1 in 3). Clinical and radiographic results of these patients were evaluated at each follow-up time (1, 3, 6, 12, 24 months after operation and the latest).

RESULTSThe average visual analogue scales score for pain was 9.3 before operation, changed to 4.3 one month after operation, further declined to 2.6 two years after operation and finally to 1.8 at the latest follow-up evaluation. Meanwhile, the average Oswestry Disability Index was 45.8 before operation, 28.6 one month after operation, 12.5 two years after operation and 8.2 at the latest followup evaluation. All operated levels but one maintained mobile and there was no significant loss of range of motion observed. Complications such as implant dislocation or significant subsidence of the prosthesis occurred in none case of this group. All patients but one (98%) were satisfied with the surgery at the latest follow-up evaluation.

CONCLUSIONSTotal lumbar disc replacement is an effective method for the treatment of degenerative disc disorders. Its long-term outcome remains to be verified.
