Objective To observe the effects of hand function training with continuous passive motion (CPM) on hand spasm and function of the hemiplegic patients.Methods 60 hemiplegic patients after stroke or brain trauma and with hand spasm were randomly divided into the treatment group and control group with 30 cases in each group. The cases in the treatment group were treated mainly with the method of CPM together with the routine rehabilitation procedures, while the those in the control group were only treated with the routine rehabilitation procedures. The changes of hand spasm and function of two groups were observed.Results After four weeks' treatment, the efficacy of the treatment group was obviously better than that of the control group ( P<0.05).Conclusion The rehabilitation training is an effective method for treatment of hemiplegia, and CPM is an important auxiliary method in the treatment. These two Methods combined together can shorten the course of treatment, and strengthen cure efficacy.

Objective To discuss the influence of age factor on the outcome of the treatment of solitary bone cyst by Depo-Medrol infiltration. Methods 24 cases with Solitary Bone Cyst were analyzed. Age ranged from 4 to 23 years old,mean 10.8. Female 9 cases,male 15 cases. Humerus 18 cases,femur 2,tibia and fibula 2,radius and ulna 1, pelvis 1.16 cases(66.6%)Solitary Bone Cyst at proximal,7 cases(29.2%)at distal,1 (4.2%)at medio. 16 cases (66.6%)on the right,8 cases(33.4% )on the left. All cases were treated with Depo-Medrol infiltration. Mean follow up period was 4.5 years; review every case's result by the X-ray and clinical signs and symptoms. Results Group A 8 cases (33.4%) healed, Group B 9 cases (37.5%) healed. There was no significant difference in the healing rate be-tween Group A and B (P=0.653). Conclusions We conclude that the healing rate can not affected by age (P=0.653). In our opinion,the origin of Solitary Bone Cyst is disturbance of bone growth on physis,so we suggest the in-sertion point of inject needles close to the physis and sufficient to touch the physis.

It is therapeutically effective to apply hemopoietic growth factors to treat hemopoietic irradiation injuries, but for other tissues injuries, hemopoietic growth factors nearly do not work. At the same time, they are only suitable for the patients with severe and lower level acute radiation sickness (ARS). Besides, clinical therapeutic efficacy of marrow transplantation is not optimistic due to difficulties of marrow zygosity and severe complications such as graft versus host disease, radiation interstitial pneumonitis. Mesenchymal stem cells (MSCs) could secret hemopoietic growth factors, rebuild hemopoietic microenvironment and be easily transfected by exogenous gene, which also have low immunogenicity. At present, studies on MSCs application in the treatment of radiation injuries are at the early -stage, but the precise mechanism is not clear. However, the specific characteristics can make up the disadvantage of traditional treatment of acute radiation sickness, and the clinical application is wide.

Silent mating type information regulation 2 homolog-1 ( SIRT1 ) is a nicotinamide adenine dinucleotide ( NAD)-dependent deacetylase, which can deacetylate histone and non-histone proteins and is involved in many life proces-ses, such as energy metabolism, cell senescence and apoptosis.SIRT1 can enhance the cellular energy supply, inhibit cell apoptosis, alleviate inflammation, enhance the resistance of oxidative stress and improve the function of endothelial cells by deacetylating relevant factors in many vascular-related diseases.This article summarizes the current research progress in the function and signal pathway of SIRT1 in ischemic stroke, atherosclerosis and tumors.

?Objective: To design a new implant distraction apparatus.Methods:The implant distraction apparatus was designed on the bases of Ilizarov theory,made of pure titanium TA 2 and prepared as a set including distractor and accessories.Inferior edge of a dog's mandible was prepared for implantation. After horizontal osteotomy, two implant distraction devices were applied.Results:The transport bone segment was vertically augmented 3 5 mm successfully,and the ditraction apparatus was stable.Conclusion: The implant distraction device is functional in distraction osteogenesis.

Objective To investigate endoscopic clipping in treating acute gastroduodenal perforation. Methods Endoscopic clipping was carried out in 22 patients with acute gastroduodenal perforation as the complication of peptic ulcer or endoscopy. Results The clipping was successful in 19(86. 4% ) of 22 patients with acute gastro duodenal perforation, and surgical therapy was performed in 3(13. 6% ) of 22 cases. A single clipping was performed in 14(73. 7% ) of 19 patients resulted in satisfactory closure of perforation. An additional clipping was needed in 5(26. 3% ) patients 24 h after the first endoscopes procedure. The effectiveness of endoscopic clipping was related to location, cause and size of the perforation. Conclusion Endoscopic clipping is an effective method for acute gastroduodenal perforation as the complication of peptic ulcer or endoscopy.

OBJECTIVE To explore the function and mechanism of the apoptosis in cochlear of mimetic aging guinea pigs treated with NGF. METHODSThe twenty-four four-month-old guinea pigs which auricle reflex were sensitive were divided randomly into three groups: A group were injected to abdominal cavity with physiological saline (2 ml/kg) ; B group were injected to abdominal cavity with 5 % D-galactose (300 mg/kg) ; C group were given 5 % D-galactose (300 mg/kg-) and NGF (1000 U/kg) respectively to abdominal cavity. Three groups had been treated two times a day for four consecutive weeks. All the guinea pigs were tested with auditory brainstem response (ABR) before the experiment and twenty-four hours after the last injection. All the guinea pigs were killed by decapitation. The cochlears were removed and fixed in different fixatives. The specimens were treated by a series of special process and the Corti organs were tested with terminal deoxynucleotidy1 transmission-mediated dUTP nick-end-labelling (TUNEL) and transmission electron microscopy respectively. RESULTS The ABR threshold of C group was apparently lower than that of B group (P

Objective To study the efficiency of endoscope-guided Savary bougie dilatation ( ESBD ) for strictured duodenal ulcer. Methods Forty-five patients with strictured duodenal ulcer were treated with endoscope-guided Savary bougie dilatation. The items of investigation were; easiness of passing the endo-scope through the strictured portion of duodenum, resolving of their symptoms and the complications happened after dilatation. Results The symptoms remitted and endoscope was advanced to descending portion of the duodenum through the stricture in all of 45 patients. The follow up period ranged from 6 months to 36 months. The rates of symptomatic remission were 97. 8% (44/45 ) , 97. 8% (44/45 ) , 94. 4% (34/36) , 93.7%(30/32) , 91.7% (22/24) and 87.5% (14/16) , at 6,12,18,24,30 and 36 months respectively. Recurrence of symptoms in patients without therapy was significantly higher than those with therapy. Conclusion ESBD is a safe and efficient procedure in treating the strictured duodenal ulcer.
