Objective To investigate the methods and effects of the pedicle modification in free flap which use medial-lower-leg-flap with a healthy limb cross-leg bridging thoracic umbilical flap.Methods From June 2006 to June 2010,twenty-eight cases with a large area of soft tissue defects caused by severe trauma were included in this study.We used The flap was used to repair the wound,the pedicle of the flap was improved which was designed by medial lower leg flap with a healthy limb cross-leg bridging thoracic umbilical flap:thoracic umbilical flap carrying the cross midline side flap.Medial lower leg flap in tongue cutting out and carrying on the medial malleolus perforator.In the processing of bridge-pedicled,we rolled the proximal porting of cross-leg flap,used medial malleolus perforator flap as a posterior wall and used thoracic umbilical flap carrying the cross midline lateral flap as anterior wall.Two portions formed a combined percutaneous tube.The two tile formmed a combined percutaneous tube.Fixing method for operation adopted external fixator which two legs were paralleling.Observation of postoperative flap survival situation,shape,color,elastic,scar contracture,and dysfunction.Results Twenty-eight cases of postoperative all flaps survived.Vascular crisis was appeared in 2 cases after 8 hours.Upon examination that was low blood pressure,low hematocrit.In treatment of transfusion and infusion,crisis mitigated.In 1 case after 12 hours with pain occurred arterial crisis,which was reliefed with analgesia.There were no vascular crisis in other 26 cases.Followed up for 2-20 months,flap had good blood supply,color and good elasticity.The appearance was not bloated and sensory recoverred partly.There was no apparent stiffness in double knee,ankle joint.Conclusion Medial lower leg flap with a healthy limb cross-leg bridging thoracic free flap transplantation for repairing serious soft tissue defects of the leg is clinically proven good means.Based on the improvement of pedicle,it can reduce the risk and complications.At the same time,it can improve the postoperative nursing care effects.It is worthy of popularization and application.

OBJECTIVE:To establish the quality standard of Fructus arctii concentrated granules. METHODS:TLC was con-ducted for the qualitative identification and HPLC was used for the content determination of arctiin in F. arctii concentrated gran-ules. The determination was performed on Dionex C18 column with mobile phase consisted of methanol-water(40∶60,V/V) at the flow rate of 1.0 ml/min. The detection wavelength was set at 280 nm,and the column temperature was 30 ℃. The samples size was 10 μl. RESULTS:TLC spectrum showed that the spots of F. arctii concentrated granules and arctiin reference medicinal material had the same color;the linear range of arctiin was 0.5-12.5 μg(r=0.999 8)with the average recovery of 98.41%(RSD=0.81%, n=9). The RSDs of precision,stability,repeatability tests were no more than 1.0%. CONCLUSIONS:The method is feasible and reproducible,and can effectively control the quality of F. arctii concentrated granules.

The evolution of the quality control concepts of medical products within the global context and the development of the quality control technology of Chinese medicine are briefly described. Aimed at the bottlenecks in the regulation and quality control of Chinese medicine, using Big Data technology to address the significant challenges in Chinese medicine industry is proposed. For quality standard refinements and internationalization of Chinese medicine, a technological innovation strategy encompassing its methodology, and the R&D direction of the subsequent core technology are also presented.

Objective To investigate the efficacy of progressive resistance exercise for improving the lower limb motor function of hemiplegic stroke patients. Methods Eighty-nine hemiplegic patients were randomly divided into a treatment group (n =46) and a control group ( n = 43 ) . Both groups received routine rehabilitation training, while the treatment group also undertook progressive resistance training. The control group received extra quadriceps femoris training. Before and after the treatment, motor function was evaluated with the Fugl-Meyer lower limb assessment, functional ambulation category (FAC) classification and the modified Barthel index (MBI). Results Before intervention, there were no significant differences between the two groups in any of the assessments. Four weeks later, all the assessment scores obtained with the Fugl-Meyer lower limb assessment, FCA classification and MBI in the treatment group were significantly better than those in the control group. Conclusion Progressive resistance training combined with routine rehabilitation treatment can improve motor function in the lower limbs, ambulation and ability in the activities of daily living of hemiplegic patients after stroke.

Objective To improve the clinical and imaging diagnosis of benign fibrous histiocytoma of bone.Methods Imaging findingsin 14 patients with pathologically confirmed benign fibrous histiocytoma of bone were analyzed.X-ray plain film was performed in allpatients,CT scan and MR scan were done in 9 cases and in 5 cases respectively.Results The clinical symptom was mainly pain in the local lesion,soft tissue mass could be felt around the lesion in 2 cases.The single-lesion was 12 cases and multi-lesion was 2 cases.There were 22 lesions in 14 cases.Most lesions localized in long bones,totally were 17 lesions.9 lesions localized in cancellous bone,8 lesions localizedin diaphysis compact substance.X-ray plain film showed centric or eccentric osteolytic destruction,unilocular or multiocular with clearborder or sclerotic border,expansion,pathologic fracture and speckled calcification in some destruction lesions.Soft tissue mass could be seen around the lesion in few cases.CT was better than X-ray plain film in displaying calcification,cyst change,pathologic fracture and soft tissue masses in the destruction portion.MR presented as homogeneous signal on T_1WI and hyper-signal on T_2WI,sometimes was inhomogeneous,speckle-like low-signal and non-signal could be seen in the lesion on T_1WI and T_2WI.Few lesion shows intermixed signal on T_1WI and T_2WI.Conclusion Based on the typical imaging and clinical features,the correct diagnosis of benign fibrous histiocytoma can be made in most cases.

Objective: To investigate the stress and coping strategy of rescue surgical staff early after earth-quake. Methods: The self reporting questionnaire (SRQ-20) and coping styles questionnaire (CSQ) were distribu-ted to 37 surgical staff and 44 psychiatric staff (the control group) in Chengdu City 2 weeks after Wenchuan earth-quake. The results were analyzed by t test, correlation analysis and logistic regression analysis. Results: The grades of rescue surgical staff in SRQ-20 and negative coping styles factor was higher than that of the psychiatric staff [(9.3±4.7)vs.(3.2±3.9), (29.8±6.2) vs.(26.1±7.1); Ps<0.05] . The SRQ-20 score in rescue surgical staffs was positively correlated with negative coping styles factor (r=0.50, P=0.002) and age (R~2=0.168, P=0.012) . Conclusion: Surgical staff, especially the elder, have more intensive acute stress reaction. It is essential to publicize psychologic knowledge and improve mental health of surgical staff.
