Objective:To investigate the operation technique and the effect of the posterior microendoscopic discectomy (MED) system on lumbar intervertebral disc hermiation (LIDH). Methods: We retrospectively reviewed and analyzed 25 cases of LVDH treated with the MED system from March 2004 to August 2005. Results: All the patients were ambulant 20 hours to 7 days (mean 2.4 days) after the operation, with a mean hospital stay of 5.2 days. And all were healed within the first stage except 1 case of infection. The patients were followed for 2-15 months (mean 6 months). Excellent results were achieved in 18 cases, good results in 5 and fairly good results in 2, the first two groups making up 92%. Conclusion: The key to successful MED with no complications is familiarity with the equipment, proper choice of indication, exact surgical location and skilful operation.

[Objective] To evaluate the curative effect of Yangyin Huayu Decoction on Chronic Obstructive Disease of Lung(CODL), its influence on blood rheology. [Method] Administer Yangyin Huayu Decoction to treatment group besides basic treatment, only basic therapy for control group. [Result] The clinical sign relieving was better in treatment group than control in marked statistical meaning, the former could also markedly improve the blood rheological indexes of whole blood mucosity, blood sedimentation square K value and packed cell volume, which was different from that of control group, in obvious statistical meaning(P

Objective To explore the early diagnosis and treatment of acute superior mesenteric arterial embolism (ASMAE).Methods The clinical data of 25 patients with acute superior mesenteric arterial embolism were retrospectively analyed.Results All 25(100%) patients had severe abdominal pain with abdominal signs,21(84%) patients had history of valvular heart disease or atrial fibrillation,and 17(68%) patients had hematochezia.All the cases were misdiagnosed preoperatively,including 11 patients were misdiagnosed as abdominal pain of unknown causes,3 patients as acute pancreatitis,3 patients as acute gastroenteritis,2 patients as necrotizing enteritis.1 patient as acute appenditis,1 patient as acute myocardial infarction,and 1 patient as acute cholecystitis;but 3 patients were preoperatively suspected to have impairment of mesenteric blood flow.All of the 25 patients underwent necrotic bowel resection,6 patients died,and 7 patients abandoned treatment because of serious complications such as short bowel syndrome etc.Mortality rate was 51%(13/25).Conclusions Early diagnosis of patients with acute superior mesenteric arterial embolism is difficult;the main cause of misdiagnosis is lack of recognition of its clinical signs.Fully grasping the characteristics of patients with early stage disease and effective early intervention are the fundamental measures for reducing mortality.

Objective To explore the method and superiority of laparoscopic management of children's varicocele. Methods High position ligation of varicocele under laparoscope was performed and internal spermatic arteries were reserved intraoperatively. Results 32 cases had smooth recovery after operation, and no complication occurred. The hospital stay was (1～3)days postoperatively. 29 cases had been followed up for 6 months～1 year and no relapse and testis atrophy occurred. Conclusions The method has the advantages of simpleness, minimal invasion and quicker recovery. Reservation of internal spermatic artery can prevent testis atrophy.

Objective: To observe the effects of different internal fixations on the treatment of pertrochanteric hip fractures. Methods: 158 cases of pertrochanteric hip fractures treated with different internal fixations, including anatomic steel, Gamma nail and dynamic hip screw, from January 1999 to October 2004, combined with functional exercise, were summarized and the advantages and disadvantages of different fixations were evaluated. Results: All of 158 cases were followed up for 6 to 36 months with a mean of 14 months. The rate of excellent or good in all patients was 94.61% by Harris criterion and 17 cases have surgical complications (10.18%). The complication rates of the three types of treatment had no difference. Conclusion: Anatomic steel, Gamma nail and dynamic hip screw are all ideal and reliable internal fixation material for pertrochanteric hip fractures as long as they are selected properly before operation.

Objective To screen the genes differentially expressed in gene expression in human lymphoma cell line Jurkat cells treated with phosphonoformate (PFA). Methods cDNA microarray technique was employed to detect the mRNA expressed in Jurkat cells treated with PFA or 0.9 percent sodium chloride, respectively. Results Among 1 152 genes there were 94 genes with different expression, of which 38 genes were upregulated and 56 genes were downregulated in Jurkat cells treated with PFA compared with those treated with 0.9 percent sodium chloride. Conclusions cDNA microarray technique was successfully used to screen the genes with different expression in Jurkat cells treated with PFA, and the results brought some new clues for the study of the immune regulation mechanism of PFA.

Objective:To study the methods of prevention and occurrence of complications in abdominal operation patients with liver cirrhosis.Methods:Analys is the occurrence of postoperative complications and influencing factors in 41 cases in abdominal diseases patients with liver cirrhosis.Results:The incidence rate of postoperative complications was 63.4%(26/41),19 patients with 1 complication,7 patients with 2 or more than 2 complications.Five patients died,Mortality was 12.2%(5/41).Ascites,Child classification,portal hypertension,esophageal varices and intraopera-tive bleeding were influencing factors of occurrence of postoperative complications in abdominal disease patients with liver cirrhos is analyzed using Logistic regression analysis.Conclusion:Positive perioperative management,reducing the intraoperative and postoperative bleeding,Intra-abdominalinfection prevention and ascitic treatment are importent factors in reducing postoperative complications and mortality.

Objective To discuss the surgical treatment for huge hepatoblastoma in children,and the technique of hepatectomy without blockade of the blood supply to the remained liver lobes.Methods We reviewed 12 cases of huge hepatoblastorna who had been operated from July 2001 to January 2009 in our hospital.The mean age of the children was 3.2 years(range,11 months to 12 years).The diameter of the tumor was from 10 to 23 cm.3～7 cycles of chemotherapy was routinely administrated before operation.When the tumor reduced to a certain size that radical resection could be performed safely,regular hepatectomy was conducted.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes was performed in every patient.Results The operations were successfully accomplished in all the 12 children.5 cases received right trihepatectomy (segment Ⅳ,Ⅴ～Ⅷ),4 cases received right hemihepatectomy(segment Ⅴ～Ⅷ),and the other 3 cases received Ⅳ,Ⅶ,Ⅷ segmentectomy,right Ⅴ,Ⅵ segmentectomy,and left hemihepatectomy respectively.The intraoperative hemodynamic parameters were stable,and there was no perioperative mortality.Postoperative chemotherapy wag routinely administrated.The follow-up period varied from 2 to 92 months.11 children survived and were disease free,among those 6 children have survived for more than 5 years.One child had brain and lung metastasis 5 months post operation,and died 7 months post operation. Conclusion Preoperative chemotherapy administrated to children with huge hepatoblastoma can reduce the tumor size and render tumor reseetable.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes is a safe and feasible surgical technique.
