Objective To investigate clinical therapeutic effects after a series of improvements of multi-site combination in the simple obese patient with tumescent liposuction. Methods Before tumescence anesthetization, short-acting benzo-diazepine was used as sedative inducer. The pressure and fluid velocity of short-acting benzodiazepine were regulated and injected into deeper level of fat at first, and all of these actions decreased the pain of patients, and promote the effect of the pain tolerance. The positions of the incisions were selected to hide from view and specifically protected, which could improve looks and decrease the scar formation after operation. In later stage of operation the flaps were pressurized and slid from outside, in order to make the flaps even and smooth and to keep their thickness according to the position of the flaps and the age of the patients. Opened draining was changed to block draining after operation. Results 73 cases were taken the follow-up for 6~24 months. All cases obtained satisfactory results, except that one cases was complicated by scar hypertrophy. The changes of the circumferences were as follows: the decrease of the maximum circumference of thigh was from 2 cm to 17cm, abdomen from 3 cm to 24 cm, and buttocks from 1 cm to 3 cm. Conclusions A series of improvement of key measures enhance the clinical therapeutic effects of multi-site combination in the simple obese patient with tumescent liposuction.

Objective To evalutate the safty of hBMSCs transpalntation and to observe their migration and distribution in the brain of young macaca fascicularis. To establish a new technology platform and theoretical basis for the treatment of central nervous system diseases in children. Methods Labelled hBMSCs were transplanted into the striatum of young macaca fascicularis. Brain sections were examined to evalutate the inflammatory reaction and immunological rejection of local injection sites by HE observation and immunohistochemical staining. Migration and distribution of transplanted?hBMSCs was observed by real?time fluorescence quantitative PCR of male DNA and fluorescence microscope. Results The results showed that the direct intracerebral injection of hBMSCs did not cause systemic symptoms in animals. There is no inflammatory reaction and immunological rejection was detected, and degeneration and necrosis of neural cells and proliferation of glial cells were absent in the local injection sites. The transplanted hBMSCs survived, and migrated into the brain after 4 weeks transplantation. Its migration and distribution have certain regularity and were overlapping between transplant recipients. In addtion, hBMSCs tended to extend rostrally into the forebrain and showed preference of migrating toward the blood vessels and below the ependyma. Conculsions Intracerebral transplantation of hBMSCs is safe. And hBMSCs can survive and migrate into the brain.

Objective: To investigate the clinical efficacy of combined acupuncture and herbal medicine based on Prof. QIN Liang-fu's experience in treating chronic gastritis. Methods: Ninety chronic gastritis patients were randomly divided into acupuncture, herbal medicine and acupuncture plus herbal medicine groups. The clinical effects were evaluated after 6 months. Results: After 6months, the clinical effect was better in the acupuncture plus herbal medicine group than in the acupuncture group and in the herbal medicine group(P< 0.05). Conclusion:The curative effect on chronic gastritis was better in the acupuncture plus herbal medicine group than in the acupuncture group and in the herbal medicine group.

Purpose To investigate the expression of Periostin and VEGF protein in esophageal squamous cell carcinoma tissue and their significance. Methods Immunohistochemical staining (SP method) was used to detect Periostin and VEGF expression in 130 cases of esophageal squamous cell carcinoma and 130 cases of normal esophageal mucosa tissues. Results There was a significantly difference between esophageal squamous cell carcinoma and normal esophageal mucoma ( P<0. 05 ) . The expression of Periostin was related to the depth of invasion and the metastasis of lymph node (P<0. 05). A dramatic correlation has been found in the expression of VEGF to the degrees of differentiation, the depth of invasion and the metastasis of lymph node (P<0. 05). The expression of Peri-ostin was also positively correlated with the expression of VEGF (P<0. 05). Follow-up data was available in 66 cases with a range of 1 to 48 months. Kaplan-Meier survival curve showed survival rate of Periostin-positive group was significantly lower than that of Perios-tin-negative group (P<0. 05). The survival rate of VEGF-positive group was significantly lower than that of VEGF-negative group (P<0. 05). Conclusion The expression of Periostin has a close relationship with VEGF in the carcinogenesis, combined detection of both Periostin and VEGF can become an objective target to evaluate Potentials of invasion and lymph node metastasis of esophageal squamous cell carcinoma, which has a great significance to the judgment of prognosis in esophageal squamous cell carcinoma.

Objective To explore the relationship of serum parathyriod hormone ( PTH) level with renal ane-mia in patients with chronic kidney disease (CKD).Methods Serum levels of PTH,Hb,Hct,BUN,Cr were observed in 126 patients with CKD at stages 3-5,the changes of 42 patients in maintenance hemodialysis(MHD) with recombi-nant human erythropoietin (rhEPO) and calcitriol-1.25(OH)2D3 treatment for three months were determined. Results The serum PTH level was significantly increased in CKD patients at stage 3 and more in CKD patients at stage 4 and 5.There were positive relationship between blood PTH and BUN ,Cr(P<0.01),but a negative relation-ship between PTH and Ccr,Hb(P <0.01).42 patients of MHD treated with rhEPO,1.25(OH)2D3 after three months,according to the changes of HCT ,the effective rate was 73.8% and the ineffective rate was 26.2%.The PTH,Hb,HCT of the effective group had statistically significant differences compared with the ineffective group ( all P<0.01).Hb and Hct significantly increased and PTH significantly decreased in the effective group .Conclusion CKD patients had decreased renal function ,elevated blood PTH .High serum PTH might aggravate renal anemia and fail to respond to rhEPO.The high serum PTH corrected by using 1.25(OH)2D3 might improve renal anemia,with high plasma PTH correcting .
