Objective To observe and evaluate clinical feasibility and efficacy of endoscopic metal stenting and combined radiotherapy in treatment of medium and late stages of esophageal carcinoma. Methods 34 cases of medium and late stages of esophageal carcin oma were treated with endoscopic stent implantation and in combination with sten t and radiotherapy. Evaluation of CES stainless metal stent on rad iation effect, clinical symptom alleviation and complication rates and survival rates in both groups was made. Results 1) CES stainless stent had no effect on radiation dosage distribution; 2) Dysphagia was markedly alleviated in both groups and no differe nce in complication rates was observed between two groups; 3) The survival rates of 6,9,12 months in patients treated with combined therapies were significantly higher than those in simple stent implantation patients. Conclusions Endoscopic metal stenting in combination with radiothe rapy was a feasible and practical management in treating medium and late stages of esophageal carcinoma, which was superior to simple metal stent implantation.

BACKGROUND: It has been reported that type 1 diabetes mellitus can result in impairments of bone regeneration and repair, and local injection of fibroblastic growth factor-2 (FGF-2) can obviously promote fracture healing, but its effect on type 2 diabetes mellitus is still unclear.OBJECTIVE: To observe the effects of recombinant human fibroblastic growth factor-2 (rhFGF-2) combined with soluble tumor necrosis factor receptor-1 (sTNF-R1) on impaired bone regeneration and repair in type 2 diabetes mellitus.DESTGN: A randomized controlled trial.SETTING: Department of Orthopaedics, the Third Xiangya Hospital of Central South University.MATERIALS: Twenty male Zucker diabetic fatty rats (ZDF/Gemi-fa/fa), 10 weeks of age, were purchased from Charles River Laboratory. rhFGF-2 was obtained from Orquest Incorporation; sTNF-R1 protein (PEG-r-metHu-sTNF-R1) was provided by Amgen Incorporation.METHODS: This experiment was finished in the central lab of the Third Xiangya Hospital of Central South University from September to November in 2006. ①Grouping: The 20 rats were randomly assigned into treated group (n =10)and control group (n =10). ② Experimental methods: All rats were examined for body mass, blood glucose, glycosuria and glycosemia. One week later, all the rats underwent the standard DO protocol, including placement of the external fixators and osteotomies to the left tibia. Distraction was initiated in the following morning (one day latency) at 0.2 mm b.I.d. (0.4 mm per day) and continued for 14 days. During surgery, all the rats received an injection of either rhFGF-2(25 mg/kg) for the treated group, or physiological saline (25 mg/kg) for the control group, into the hematoma of the osteotomic gap. The sTNF-R1 (8 mg/kg) or the same. Amount of saline was subcutaneously injected into the treated and control rats respectively every other day for 14 days. Evaluation: The serum biochemical indexes, amount of bone formation and number of proliferative cells in the distraction gaps were determined.MAIN OUTCOME MEASURES: Biochemical indexes, amount of bone formation and number of proliferative cells in the distraction gaps.RESULTS: All the 20 rats were involved in the final analysis of results. ①The blood glucose, glucosuria, ketonuria,serum levels of insulin and osteocalcin were not obviously different between the treated group and control group (P ＞0.05). ② The area and density of mineralization of the distraction gaps, and the endosteal and peristeal new bone formation in the treated group were all obviously higher than those in the control group (P ＜ 0.05-0.01). The number and percentage of the positive cells of proliferating cell nuclear antigen (PCNA) in the distraction gaps were obviously higher in the treated group than in the control group (P ＜ 0.05-0.01).CONCLUSION: The local application of rhFGF-2 combined with sTNF-R1 can enhance bone formation by increasing the proliferation during distraction osteogenesis in ZDF rats. The combination of rhFGF-2 and sTNF-R1 may be an effective treatment for type 2 diabetic patients with fracture healing problem.

Objective: To explore influence of exercise on cardiac autonomic nerve function in patients undergoing coronary artery bypass grafting (CABG) and its clinical significance. Methods: A total of 53 patients with coronary heart disease undergoing CABG were randomly divided into routine treatment group (n=25) and rehabilitation group (n=28, received exercise training based on routine treatment). Changes of autonomic nerve function before, second and eighth week after CABG were analyzed in two groups using time domain indexes of heart rate variability (HRV) by ambulatory electrocardiography, including standard deviation of normal to normal RR intervals calculated over the 24 h period (SDNN), standard deviation of normal to normal RR intervals in all 5 min segments of the entire recording (SDANN), root-mean square of differences between successive normal to normal intervals (rMSSD) and adjacent normal RR interval difference > 50ms stroke accounted for a percentage of 24h total RR interval (PNN50). Results: Compared with before CABG, there were significant decrease in SDNN, SDANN, RMSSD and PNN50 in both groups two weeks after CABG (P<0.05~0.01); eight weeks after CABG, above indexes recovered to levels before CABG in routine treatment group[SDNN （113.6±29.4）vs.（116.7±24.7）, SDANN（112.2±32.1）vs.（113.6±28.6）, rMSSD（21.9±8.2） vs.（23.2±7.1）, and PNN50 （7.5±4.2）vs.（8.2±3.7）] , P>0.05 all; Compared with before CABG, there were significant improvements in SDNN [(114.7±25.2) ms vs. (132.6±30.6) ms], SDANN [(111.6±23.5) ms vs. (129.2±30.8) ms], rMSSD [(24.2±8.7) ms vs. (29.9±7.5) ms] and PNN50 [(7.8±2.2) ms vs. (9.5±2.3) ms], and there were significant improvement than those of routine treatment group [SDNN （132.6±30.6）vs.（113.6±29.4）, SDANN（129.2±30.8）vs.（112.2±32.1）, rMSSD（29.9±7.5）vs.（21.9±8.2）and PNN50 （9.5±2.3）vs.（7.5±4.2）] eight weeks after CABG in rehabilitation group, P<0.05 all. Conclusion: All HRV indexes significantly decrease on two weeks after CABG in both groups, suggesting that CABG can damage cardiac autonomic nerve system. These indexes of rehabilitation group were more improvement than those of routine treatment group, suggesting exercise training can more significantly improve cardiac autonomic nerve function after CABG.

OBJECTIVETo observe analgesic and sedative effect of acupuncture combined with medicine (ACM) on patients undergiong cardiac surgery.

METHODSA total of 50 patients with cardiac surgery from January 2012 to October 2014 were randomly assigned to the conventional analgesia group (group A) and the ACM analgesia group (group B), 25 in each group. Patients in group A were subjected to analgesia and sedation by injecting dexmedetomidine, while patients in group B were subjected to analgesia and sedation by electro-acupuncture [EA, Shenting (GV24); Yintang (EX-HN3)] combined with injection of dexmedetomidine. Morphine hydrochloride injection was performed when analgesia and sedation effect was ineffective in the two groups. The indicators of patients at different time points in the two groups were observed, such as static and dynamic VAS scores, SAS scores, mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SpO2). The injection dosage of dexmedetomidine and morphine hydrochloride, analgesia satisfaction rate, sedation satisfaction rate, the incidences of adverse reactions during treatment such as bradycardia and low blood pressure, mechanical ventilation time, ICU time, and hospitalization expense were observed and recorded in the two groups.

RESULTSThere was no statistical difference in static and dynamic VAS scores, SAS score, MAP, HR and SpO2 between the two groups at different time points (P > 0.05). The injection dosage of dexmedetomidine and morphine hydrochloride was significantly reduced in group B than in group A (P < 0.05). The analgesia satisfaction rate of patients in group B was much higher than that in group A (P < 0.05). The incidence of bradycardia also obviously decreased more in group B than in group A (P < 0.05). There was no statistical difference in patients' sedation satisfaction rate, incidences of low blood pressure, delirium, vomiting; mechanical ventilation time, ICU time, or hospitalization expense between the two groups (P > 0.05).

CONCLUSIONThe analgesia method of ACM could reduce the dosage of traditional analgesic drugs and the occurrence of partial adverse reactions.
