Objective To study the clinical results of grafting of vascularized fibular and ilium to repair bone defects of limbs. Methods From January 1992 to January 2004, 49 cases of bone defects of limbs were treated with vascularized fibular grafting (33 cases) and vascularized iliac grafting (16 cases). Their limb functions were graded according to Ennekings system. The changes of the vascularized fibular and iliac grafts were evaluated radiographically according to the International Symposium on Limb Salvage. Results All the patients were followed up for 1 to 12 years. In the vascularized fibular group, the recovery rate for the operated limbs was 82.7%, the average healing time of the bone was 16.8 weeks and the healing rate of the bone was 87.9%. In the other group, the recovery rate of the operated limbs was 88%, the average healing time of the bone was 15.2 weeks and the healing rate of the bone was 93.8%. Conclusion The vascularized fibular graft can be adopted to repair long bone defects of lower limbs and distal radius, while the vascularized iliac graft can be adopted to repair the bone defects of upper limbs.

The Acetobacter xylinum and Schizosacchromyces sp. were isolated from tea fungus culture. Each strain 's function on the production of antibacterial protein was explored by single-strain culture and double-strain culture under various condition. The preliminary conclusion is that the protein is synthesized by the yeast cells and its antibacterial activity is significantly improved through modification by bacteria enzymes. The results of co-cultures of several yeasts with the Acetobacter xylinum show that Schizosacchromyces is superior to other yeasts.

BACKGROUND: Due to a new finding in the in vitro proliferation and differentiation of neural stem cells, neural stem cells are regarded as optimal materials for repairing and replacing the injured neural tissues. But how to enhance the proliferation of neural stem cells and how to induce neural stem cells to differentiate into certain phenotypes remain objects for discussing.OBJECTIVE: To investigate the frozen/nonfrozen storage techniques in isolation and cultivation of neural stem cells isolated from human brain and to discuss the conditions suitable for their differentiation.DESIGN: A single sample based on cells.SETTING: Urinology Institute of Jiangxi Medical University and Neurosurgery Department of Second Hospital Affiliated to Jiangxi Medical College.MATERIALS: From December 2003 to June 2004, this study was conducted at the Urinology Institute of Jiangxi Medical College. Brain tissues removed from sixteen-week-old embryos were studied.METHODS: After being digested with trypsin, cells were separated from the brains of embryos. They were cultured in the serum-free media, stimulated by basic fibroblast growth factor and epidermal growth factor and were induced to differentiate using serum. Immunofluorescent cytochemical staining technique was adopted to detect the expressions of the Nestin and the neuron-specific enolase(the marker for mature neural cells) in these cells. The influence of basic fibroblast growth factor, epidermal growth factor and serum on the proliferation and differentiation of the neural stem cells were investigated.MAIN OUTCOME MEASURES: The main outcome measurements in this tification of the Nestin and the neuron-specific enolase in these cells.bryo brain successfully. The embryo brain cells in primary culture were clear and round. After 3 days some cells aggregated to form neurospheres and some others suspended. Two weeks later, the neurospheres enlarged and a part of cells in it expanded into folds with strong reflection and proliferation. The continuous cultured cells inherited these characteristics and kept the morphological properties. The clones were cultured in the medium with serum. Twenty-four hours later, most of the cells were attached to the bottom of the plates. Cells were dissociated from the neurospheres and became irregular. Forty-eight hours later, most of the cells differentiated into many scattered patches of astrocytes with various shapes and neurites and many isolated neural stem cells were continuously cultured in vitro and they expressed Nestin, the marker of neural stem cells. After being cultured in medium with serum for 48 hours, the differentiated cells mainly expressed freeze-thaw cells were alive. Their living status had no significant difference compared to that of the fresh isolated cells.CONCLUSION: Serum-free culture medium, together with basic fibroblast growth factor and epidermal growth factor, enables the in vitro culture, proliferation and purification of the neural stem cells. The feasibility of the method is confirmed. Meanwhile, the comparison between the cultures of freeze-thaw cells and fresh isolated cells indicated that frozen storage can be used as a way to preserve the human embryo brain cells, which will be available for study after thaw.

Objectives: To investigate the affecting factors on expenditure in Medical insurant inpatients. Methods: 593 medical insurant inpatients, who were from Feb 1, 2001 to Feb 31, 2002 in Nanjing Jinling hospital, were enrolled in this study. The inpatient expenditure was analyzed from the aspect of operation or not, age, and payment mode, used the descriptive analysis and multi factor analysis on affecting factors of the total expense, self bearing expense, and self affording expense. Results: The hospitalized days, operation or not, severity of disease were important affecting factors. The self bearing expense of medical insurant inpatients was associated with hospitalized days, operation or not, and total expense. While the self affording expense of them was associated with expense of drug, hospital bunk, radiation and others. Conclusions: We can control these associated affected factors to lighten the economic weight of patients, and to reduce the ratio of individual payment.

Objective To explore the clinical value of transumbilica single-port laparoscopic surgery in the treatment of bilateral varicocele.Methods From Jan. 2010 to Sep. 2010,42 patients with bilateral varicocele underwent laparoscopic high ligation of bilateral spermatic vein.Of these patients,20 were treated with transumbilica single-port laparoscopic surgery,22 with traditional laparoscopic surgery.The two groups of patients were compared for the parameters such as intraoperative blood loss,testicular artery preservation,operating time,time of activities after surgery,time of intestinal function recovery and hospitalization duration.The semen quality 1 year after the surgery was compared with that before treatment.At the out-patient re-examination at 1,3,6months and 1 year after the surgery,the incision,scrotum,spermatic cord,testis were checked for possible complications.The relief of discomfortness in the scrotum was also followed up.Results Both operation procedures were successful,without severe complications.In the single-port laparoscopic surgery produced blood lose ( [ 5 ± 1 ] ml vs.[ 5 ± 1 ] ml,t =- 0.452,P ＞ 0.05 ),the operating time ( [ 41 ± 7 ] min vs.[ 39 ± 3 ] min,t =0.686,P ＞ 0.05 ),postoperative intestinal function recovery time ( [ 11 + 1 ] h vs.[ 11 + 2 ] h,t =- 1.631,P ＞0.05 ) and postoperative hospital stay ( [ 3.1 + 0.7 ] d vs.[ 3.4 + 0.7 ] d,t =- 1.447,P ＞ 0.05 ) which were all comparable to that from conventional laparoscopic surgery.There was significant difference in the population using analgesics,single-port laparoscopic surgery vs.conventional laparoscopic surgery ( 1 case [ 5.0％ ] vs 7case [ 31.8％ ].The difference was statistically significant (x2 =4.886,P ＜ 0.05 ).The single-port laparoscopic surgery produced neglectable scar at the incision.All of the patients were questionaired for their satisfaction with the incision 1 year after the surgery.The difference was statistically significant (x2 =7.636,P ＜ 0.01 )Conclusion Single-port laparoscopic high ligation of bilateral spermatic vein produces comparable outcomes to that of conventional laparoscopic surgery,but it is a more microinvasive procedure producing good aesthetic appearance,representing the trend of laparoscopic technique.
