Balance function is one of injured functions needed rehabilitation after stroke. It is also the considerable signal of the restoration for motor function, which being thought highly in the field of rehabilitation. In some aspect, the restoration of balance function cannot be substituted by stance. The authors mainly discussed the mechanism and issues of balance training by which the balance function of stroke patients in chronic period improved, based on nerve compensative mechanism.

Objective To investigate the effects of mild pefioperative hypothermia on cellular immune function in patients undergoing surgery for rectal cancer.Methods Fifty ASA Ⅰ or Ⅱ patients aged 30-64 yr undergoing surgery for rectal cancer were randomly divided into 2 groups ( n =25 each):mild hypothermia group and normal body temperature group.Anesthesia was induced with midazolam,fentanyl,etomidate and vecuronium and maintained with propofol,remifentanil and vecuronium.The patients were mechanically ventilated after tracheal intubation.PET CO2 was maintained at 35-45 mm Hg.The venous blood samples were taken from peripheral vein at 1 h before anesthesia (T1 ),at the end of operation (T2),at 24 h after operation (T3),and on 7th day after operation (T4) to measure the serum Th1 and Th2 cytokines levels and Th1/Th2 cytokines balance was observed.Results Compared with the baseline value at T1,the serum Th2 cytokines level was significantly decreased and Th1/Th2 ratio was significantly increased at T4 in normal body temperature group,and the serum Th1 cytokines level and Th1/Th2 ratio were significantly decreased and the serum Th2 cytokines level was significantly increased at T2.3 in mild hypothermia group ( P ＜ 0.05).Compared with normal body temperature group,the serum Th1 cytokines level and Th1/Th2 ratio were significantly decreased and the serum Th2 cytokines level was significantly increased at T2-4 in mild hypothermia group ( P ＜ 0.05).Conclusion Mild perioperative hypothermia can depress cellular immune function in patients undergoing surgery for rectal cancer.

Objective To investigated the clinicopathological findings and prognosis of 60 patients with pleomorphic carcinoma.Methods 60 cases of pleomorphic pulmonary carcinoma were collected and studied clinicopathologically between 1999 and 2011.All patients underwent pulmonary resections.Results There was no in-hospital death.1 had haemothorax that required reoperation,1 patient had a late cicatricial bronchial stenosis after sleeve lobectomy of the upper right lobe,and treated successfully by the resection of the right two lobes.The 3,5-year survival rates of all patients were 47.2％ and 25.6％ respectively.For N0 and N1-N2 patients,3-,5-year survival rates were 57.3％,32.5 ％ and 25.4％,17.1％,respectively.Overall survivals were of significant difference between radical resection and uncomplete resection.Multivariate Cox regression analyses of overall survival of all 60 patients indicated that radical resection (P =0.041) and nodal status (P =0.029) were significant independent prognostic factors.Conclusion Pleomorphic carcinoma is a rare type of lung cancer.Pleomorphic carcinoma of the lung was often found as a large mass peripherally located and was associated with poor prognosis.Radical resection and nodal status were significant independent prognostic factors.

Aim To investigate the effects of masculine drug Duxil on striatum extracellular acetylcholine(ACh),glucose and lactic acid(LD) levels in energy metabolism impairment rats induced by intracerebral perfusion with sodium azide(NaN3).Methods Rats were divided into three groups:control,model and Duxil groups.Rats of Duxil group were treated with 10 mg?kg-1?d-1 Duxil for 14 d.Other two groups were treated with water for 14 d.After 2 wk microdialysis technique was adopted and the rats were perfused with NaN3 in striatum and continuously measured striatum extracellular ACh,glucose and LD levels in freely moving awake rats.Results During perfusion(90 min) and stoping perfusion(180,240,360 min)period with NaN3 striatum extracellular ACh levels in the model group were significantly lower than those in the control group(P

Objective To explore the effects of application of laparoscopic simulators in teaching of plastic surgery. Methods 10 plastic surgeons and 20 standardized training surgical residents with 2 to 4 years' experience were tested about their proficiency in moving beans, pinching, suturing and tying by timing and counting. After they were trained with laparoscopic simulators 3, 6, 9 times with each time for 90 min, tests were taken. SPSS 19.0 was used to make single factor variance analysis of the related data or conduct q test. Result There was significant difference before and after the residents' training of moving beans, pinching, suturing and tying (P<0.05). Less time to finish the operation was needed after training, but after training for 6 times or 9 times, there was no significant difference in operation time (P >0.05). Conclusion Application of laparoscopic simulator training can significantly improve the operation skills of the novices with some clinical experience in the short term, which is conducive to the endoscope assisted breast augmentation surgery, and is worthy of promotion.

Objective To explore the survival condition of hemodialysis patients in Ningxia Hui Autonomous Region. Methods Interviewed 15 patients with hemodialysis by applying Modified Grounded Theory Approach put forward by KinoSitaYasuHito,a Japanese scholar,the data of which were from qualitative inductive comparative analysis. Results As for the survival condition of hemodialysis patients in Ningxia,two relative themes were extracted, Helpless dialysis life Desire to return to society, the former contained 2 subtopics of hardship in life and susceptible mood, the latter contained 2 subtopics of cherish life and desire for care. Conclusion We should set up a social supporting system to improve the living condition of hemodialysis patients with the purpose of helping them return to the society.

Background and purpose:In recent years,sleeve resection of bronchus and pulmonary artery has been more extensively applied in treatments of lung cancer patients with poor pulmonary functions.This kind of surgery meets the basic surgical principles of lung cancer being maximum both in resecting the carcinoma of the lungs and preserving pulmonary functions,has a good prospect.Therefore,we summarize our recent experience in treating central type lung cancer by this method and discuss its principles and methods in the application of the surgical operation.Methods:From Dec.1993 to Dec.2003,63 patients with central type lung cancer underwent sleeve lobectomy of bronchus and pulmonary artery,including sleeve resection of bronchus and pulmonary artery in 43 cases,wedge resection of bronchus and pulmonary artery in 3 cases,sleeve resection of bronchus and wedge resection of pulmonary artery in 17 cases.The surgical procedures of sleeve resection included sleeve resection of right upper lobe and pulmonary artery in 20 cases,sleeve resection of left upper lobe and pulmonary artery in 23 cases,and the length of pulmonary artery that had been respected is from 1.5cm to(4.5cm),the average length is 2.5cm.The surgical procedures of wedge resection included wedge resection of right upper lobe and pulmonary artery in 2 cases, wedge resection of left upper lobe and pulmonary artery in 1 case.The group of sleeve resection of bronchus with wedge resection of pulmonary artery included sleeve resection of right upper lobe and wedge resection of pulmonary artery in 5 cases,sleeve resection of left upper lobe and wedge resection of pulmonary artery in 12 cases.Results:No case of death and anastomotic leak occurred.Conclusions:Because sleeve resection of bronchus and pulmonary artery can not only effectively resect the tumor but also maximally preserve the pulmonary function at the same time,it enlarges the surgical indications of lung cancer,and is an effective and safe method for the treatment of lung cancer.
