Objective To report the clinic experience of tr eatment of severe pelvic fracture in order to improve the early diagnosis and operation of the injury.Methods We retrospectively studied the clin ic data of106patients admitted to our hospita l for severe pelvic fracture from Apr il 1994to May 2002.Results The main causes for pelvic fracture were traffic accident injury(69cases,65.1%)and falling accident injury(31cases,29.3%).87cases were in the survival group,and 19cases in the death group,with t he mortality of about 17.9%.In the death group,10di ed from hemorrhagic shock,4of severe cerebral injury,3from MOF,and 2from ARDS.32cases with pelvic f ractures were treated by opening red uction and internal fixation,91.7%of which achieved good results.Conclusion In the treatment of severe pelvic fra ctures,prehospital emergency care is very important.Complicated severe injuries should be treated pr omptly and pelvic fractures be fixed with internal fixation as soon as possibl e.

BACKGROUND: The free border of meniscus is avascular portion, for which, it is not susceptible for the meniscus to be cured naturally after injury. Therefore, it is necessary to induce fibrous tissue healing probably under certain situation.OBJECTIVE: To adopt tissue engineered cartilage and fibrin adhesive to treat meniscus injury in avascular portion and compare the results.DESIGN: Randomized group division and blank control experiment was designed.SETTING: Animal Laboratory of a Shenzhen Second People's Hospital.green-purplish-blue adult rabbits were selected, randomized into 3 groups,12 rabbits in each, named blank control, fibrin adhesive group(FA group)and tissue engineered cartilage group(TE-C group).METHODS: The experiment was performed in Animal Laboratory of Shenzhen Second People's Hospital from September 2003 to March 2004.Ten baby rabbits borne in 3 to 5 days were sacrificed to collect fibrochondrocytes for culture so as to prepare tissue engineered cartilage containing 12 × 108 L-1chondrocytes. Thirty-six adult rabbits were prepared into the injured model in avascular portion of meniscus (0. 7 × 0. 3) cm with full-thickness laceration. In blank control, no any filler was applied for management; in FA group, fibrin adhesive was infused in laceration; and in TE-C group, tissue engineered cartilage was infused in laceration. Four animals of each of 3 groups were sacrificed in the 2nd, 6th and 12th weeks after operation. Eight menisci were collected in each group each time for gross morphological observation and histological examination.MAIN OUTCOME MEASURES: Gross morphological observation and histological examination in injured meniscus model of rabbit.logical observation in injured meniscus model of rabbit: In blank control, the splits in meniscus were not been healed and tissue filler was not apparent. In FA and TE-C groups, the splits had been filled up with tissue fillers comblank control, 2 to 12 weeks after operation, there was chondrocyte proliferation presented on the border of splits. In FA group, 12 weeks after operation, on the defect border, there were many fibroblastic cells that closely adhered to adjacent tissue, resulting in scar tissue healing. In TE-C group,12 weeks after operation, cartilage cavities and capsule were apparent in the defect and chondrocftes were in cell condensation.CONCLUSION: Tissue engineered cartilage is survived in the acceptors, resulting in fibrocartilaginous healing and specific biological label of chondrocytes. But the remarkable difference presents in collagen arrangement among the repaired tissue, adjacent normal meniscus tissue and normal cartilage.

Objective To preliminary screen serum microRNA which was related to class Ⅳ and class Ⅳ+Ⅴ lupus nephritis (LN)by using microRNA array technology,and explore the role of serum microRNA in renal pathological classification of lupus nephritis.Methods Eight serum samples of lupus nephritis patients from biological specimen library in our hospital were enrolled. Experimental group was composed of 4 class Ⅳ cases and 4 class Ⅳ+Ⅴ cases,control group was composed of 4 healthy persons. MicroRNA array was used to screen the differentially expressing microRNA.Results There were part of same miRNA in class Ⅳand classⅣ+Ⅴ LN,among which expression of 22 miRNA were significantly different,29 miRNA of classⅣ was unique,3 miRNA of class Ⅳ+Ⅴ was unique.Conclusion Serum miRNA has a potential to serve as a biomarker to identify class Ⅳ and classⅣ+Ⅴlupus nephritis.

Recent years, the pathogenesis of hypertension in traditional Chinese medicine (TCM) has been changed. Kidney-deficiency has become the key of modern pathogenesis, and the new problem of treating hypertension. It has become the new strategy for treating hypertension with kidney-nourishing herbal medicine. This article reviewed the clinical and experimental researches of kidney-nourishing herbal medicine, including single herb, herbal formulae and traditional Chinese patent medicine, in order to strengthen the evidence of kidney-nourishing herbal medicine for treating hypertension.

In order to develop safe training intensity and training methods for the passive balance rehabilitation train- ing system, we propose in this paper a mathematical model for human standing balance adjustment based on T-S fuzzy identification method. This model takes the acceleration of a multidimensional motion platform as its inputs, and human joint angles as its outputs. We used the artificial bee colony optimization algorithm to improve fuzzy C--means clustering algorithm, which enhanced the efficiency of the identification for antecedent parameters. Through some experiments, the data of 9 testees were collected, which were used for model training and model results validation. With the mean square error and cross-correlation between the simulation data and measured data, we concluded that the model was accurate and reasonable.

This article is to overview the literature of syndrome differentiation of traditional Chinese medicine on hypertension. According to the theory of disease in combination with syndrome, we concluded syndrome types of hypertension in four aspects, including national standards, industry standards, teaching standards and personal experience. Meanwhile, in order to provide new methods and approaches for normalized research, we integrated modern testing methods and statistical methods to analyze syndrome differentiation for the treatment of hypertension.
