Objective To evaluate the efficacy of the nerve grafting and nerve transfer (neurotization) in the treatment of early obstetrical brachial plexus palsy(OBPP). Methods 48 cases with TassinⅡ-Ⅳ lesion who had no any recovery of elbow flexion, the brachial plexus were explored from 3 to 14 months after birth. The method of nerve repair depended on findings during operation. For the traumatic neuroma, it should be resected and the defect be repaired by nerve grafting with neurotization; the root avulsion was repaired by neurotization; neurolysis was only performed to those plexus that looked nearly normal and had a positive reaction of neurophysiology as tested intra-operatively. The reconstructive procedures included: C5→upper trunk, accessory →supraspinal nerve (2 cases); C5,6→the posterior and the anterior division of the upper trunk respectively, accessory →supraspinal nerve (25 cases); C5,6→the posterior and anterior divisions of the upper trunk respectively, C7→middle trunk, accessory →supraspinal nerve (4 cases); C5→posterior cord, C6→lateral cord, accessory →supraspinal nerve (5 cases); C5→anterior division of the upper trunk, C6→C8, accessory →supraspinal nerve (1 case); C5-7→the posterior, lateral and medial cords respectively, accessory →supraspinal nerve (4 cases); C5→upper trunk, C6→lower trunk (or medial cord), accessory →supraspinal nerve (2 cases); C5,6→the lateral and medial cords respectively, accessory →supraspinal nerve (3 cases); neurolysis (2 cases). Results All the patients were available at follow-up at least for 36 months, who were studied according to both of the Gilberts shoulder and elbow rating system and the Raimondis hand scale system. The score of shoulder, elbow, and hand in 13 cases with Tassin Ⅱ lesion improved from preoperative 0.54, 1.92 and 3.23 to postoperative 3.77, 4.92 and 4.31 respectively; 11 cases with Tassin Ⅲ rose from 0.46, 1.82 and 1.91 to 3.27, 4.18 and 3.64, and 24 cases with Tassin Ⅳ had an elevation from 0.25, 1.25 and 0.33 to 2.92, 3.46 and 2.83. The medial rotation contracture of the shoulder without subluxation and dislocation was found in 7 cases(14.6%) in the process of recovery. Conclusion The resection of the traumatic neuroma combined with nerve grafting and neurotization is really effective in the treatment of early OBPP.

Objective To investigates the possible methodes for adult human Schwann cell culture and proliferation with F-12 medium which could be used on human body. Methods Nineteen human peripheral nerves were used in this study, 12 of them were cultured under F-12 medium and the other 7 nerves under standerd medium. The medium were changed every 2 days, and the nerve tissues were transfered to another plate when there were too many cells, after 6-8 times of transferring, most of the cells were Schwann cells and the nerve tissues were digested using none cell toxic collagenas. The cells were counted and evaluated the survival rate with Live-Dead kit S-100 protein immunostaining was used to assesse the Schwann cell purity. Results The survival rate of the cells were 85.54% and 86.93% , and the Schwann cell purity were 82.64% and 86.37% respectively, there were no difference between the two different medium, but we got more cells from F-12 medium than Standard medium, which was 14.2?10~7 and 5.9?10 respectively. Conclusion The F-12 medium could be used for human Schwann cell culture, meanwhile it had possible function on Schwann cell proliferation.

Objective To evaluate the chnical value of intervention therapy combined with the foot plastic surgery in the treatment of diabetic foot.Methods 67 patients who accepted the intervention therapy combined with the plastic surgery for occlusive lesion of lower limbs arteries were selected.The clinical symptom,ankle brachial pressure index and hemodynamics were observed before and after treatment.All clinical indicators were compared between the therapeutic group and the control group.Results Among 67 patients,63 cases were successful in clinical treatment (the success rate:94.0％).One month,three months,six months after operation,the skin temperature,anklebrachial index,limp distance,clinical symptom,ankle brachial pressure index and hemodynamics were increased.Compared with preoperation,all above-mentioned indicators were improved obviously (P ＜ 0.05,P ＜ 0.01).Conclusion Intervention therapy for diabetic foot has the merits of less trauma,higher effectiveness of treating diabetic foot ulcers,defect repair,maximally reserved limbs and better shapes of limbs,which made both doctors and patients satisfied.It is a new direction for minimally invasive therapy.

Objective To observe the effect of different concentration netrin-1 on retinal vascular permeability in diabetes mellitus (DM) rats.Methods Eighty adult Sprague-Dawley rats were randomly divided into 8 groups,10 rats in each group,including normal control group (group A),normal+balanced salt solution (BSS) group (group B),normal+netrin-1 (500 μg/ml) group (group C) and DM group (50 rats in 5 subgroups).DM rats were induced by intraperitoneal injection of streptozocin.Three months after intraperitoneal injection,10 DM rats in the control group were injected with BSS (group D).Forty DM rats were injected with 5 μl of different concentrate netrin-1,and were divided into DM+netrin-1 10 μg/ml group (group E),DM+netrin-1 50 μg/ml group (group F),DM+netrin-1 100 μg/ml group (group G),DM+netrin-1 500 μg/ml group (group H)according to the different concentration.Non-DM rats in group C were injected with netrin-1 500 μg/ml.The expression of occludin was determined by immunohistochemistry for protein,and by real-time fluorescence quantitative reverse transcription polymerase chain reaction for mRNA level.Retinal vascular permeability was measured by Evans blue infusion.Results The expression of occludin protein and mRNA in group D were less than group A (t=27.71,8.59;P=0.00,0.00).However,the retinal vascular permeability increased in group D (t=-42.72,P=0.00).The expression of occluding protein,occludin mRNA and retinal vascular permeability showed significant differences between group D,E,F,G and H (F=146.31,16.54,67.77;P=0.00,0.00,0.00).Compared the group B with group C,there was no significant differences between the expression of occludin protein,occludin mRNA and the retinal vascular permeability (t=-1.13,0.93,1.04;P=0.27,0.36,0.31).The concentrate of netrin-1 showed a significant positive correlation to the expression level of occludin and occludin mRNA (r=0.73,0.81;P=0.00,0.00),but negative correlation to the vascular permeability (r=-0.61,P=0.00).Conclusion Netrin-1 can reduce the DM rats' retinal vascular permeability,which depended on the concentration of netrin-1.

Objective To investigate spiral CT,PET/CT and clinical manifestations in non-HIV infectious penicilliposis marneffei lung disease, to improve diagnostic level of this disease.Methods Imaging manifestations of 6 cases of non-HIV infectious penicilliposis marneffei confirmed by bronchofiberscope lung biopsy and/or pus culture were analyzed retrospectively All cases underwent chest CT,two had brain MRI,and two had PET/CT scan before treatment.Imaging appearances were observed and combined with clinical dates and literatures.Results Unilateral lung lesion was detected in 1 case,bilateral lungs lesions in 5 cases.Multiple patchy consolidation,stripe shadow in bilateral lungs or right lung were found in 3 cases, multiple nodes in 2 cases, mass with nodes in 1 case.Among 6 cases, 2 had septa interlobulare thickness,1 had tracheal fistula,2 had pericardium and pleura involvement,4 had bone destruction,1 had the brainand liver involvement.6 cases showed multiple lymphadenectasis,amalgamation and necrosis in bilateral hilar,mediastinaand the neck.2 had abdominal cavity and or retroperitoneal lymphadenectasis.On PET/CT,2 cases showed high uptake,and the range of SUV value were 1.4-13.9.Initial misdiagnosis by imaging was found in 5 cases.6 patients recovered after anti fungus treatment.Conclusion Imaging appearances of non-HIV infectious penicilliposis marneffei mainly reveals as multiple patchy consolidation,nodes and mass in bilateral lungs, all accompany with lymphadenectasis, many with bone destruction,lack of specificity, which needs lesion biopsy and pus culture to make confirmed diagnosis.

During the process of China’s healthcare reform, the concept of “costly access to health care” has been discussed for quite a long time. However, big data indicates that a small number of patients (5%) account for disproportionate costs ( approximately 50%) . “Costly access to health care” may not be a ubiquitous perceived prob-lem for all residents. In this paper, the concept“high-need patient” will be introduced and the characteristics of the population will be analyzed. According to the healthcare reform experience from the international perspective, this paper proposed healthcare strategy for Chinese high-need patients and policy recommendations for China’s healthcare reform.

Objective By comparing the therapeutic effects of different nutrition support,to elementarily evaluate the protocol of nutrition support with ω-3 polyunsaturated fatty acids in patients undergoing hepatectomy.Methods Retrospective and comparative analysis was applied.From January 2009 to January 2011,82 patients undergoing liver resection were selected from Nanjing Drum Tower Hospital and divided into three groups according to different nutrition supporting protocol:total parenteral nutrition group (23,TPN for short),combined enteral nutrition group (30,EN for short),ω-3 PUFAs group (29).TPN group was given total parenteral nutrition.EN group was given both parenteral and enteral nutrition.ω-3 PUFAs group was given parenteral nutrition,enteral nutrition and ω-3 PUFAs.By comparing the general situation,the incidence of post-operation complications and index of liver function,the effect of different nutrition supporting plans could be comprehensively evaluated.Results (1) None patients from any groups had severe complications such as bile leakage and hemobilia.Slight complications included ascites and pleural effusion.No difference is of significance in statistics science.(2) Compared with TPN group,patients from EN and ω-3 PUFAs group had shorter defecating time and post-surgery hospital stay,the difference is of significance in statistics science (P =0.001,t =4.624; P =0.001,t =5.019).There was no significant difference between EN and ω-3 PUFAs group (P ＞ 0.05).(3) For patients received operation with major hepatectomy (≥4 segments),ALT in ω-3 PUFAs group was lower than EN group in the 3rd and 5th day after operation (P=0.024,t =2.432; P=0.042,t =2.144).(4) For patients with cirrhosis,TB in ω-3 PUFAs group was lower than EN group in the 3rd and 5th day after operation (P =0.032,t =2.202; P =0.035,t =2.183).Conclusions It is beneficial to use nutritional support in patients received hepatectomy.For patients received major hepatectomy and patients with cirrhosis,nutrition support with ω-3 PUFAs had better protective effects.

Free latissimus dorsi muscle transfer is widely used for functional reconstruction of flexion of elbow and fingers after brachial plexus injury at later stage, as well as for soft tissue coverage because of its large size and long and reliable pedicle with adequate vessel diameter. Common complications recorded in literatures are hematoma and muscle atrophy due to a compartment syndrome. We treated a patient with soft tissue avulsion at forearm using free latissimus dorsi muscle transfer for soft tissue coverage in our hospital. Unfortunately during the transfer the patient's brachial plexus was injured. After timely treatment, he recovered completely.

OBJECTIVETo observe long-term functional recovery after contralateral C7 transfer.

METHODSFrom August 1986 to July 2000, 224 patients with brachial plexus avulsion injuries were treated with contralateral C7 transfer in our department. Thirty-two patients were followed up for over 2 years for evaluation of the following items: 1 influence on healthy limb function; 2 sensory and motor recovery of the recipient nerves in the affected limb; and 3 coordination between the healthy and affected limbs.

RESULTSThere was no impairment of healthy limb function. Functional recovery of the recipient area reached > or =M3 in 8 patients (8/10, 80%) after musculocutaneous nerve neurotization, > or =M3 in 4 patients (4/6, 66%) after radial nerve neurotization, > or = M3 in 7 patients (7/14, 50%) and > or = M3 in 12 patients (85.7%) after median nerve neurotization, and > or = M3 in 1 patients (1/2, 50%) after thoracodorsal nerve neurotization. Synchronic contraction of the affected limb with the healthy limb occurred within 2-3 years in 12 patients, within 5 years in 13 patients, and over 5 years in 7 patients.

CONCLUSIONContralateral C7 transfer is an ideal procedure for the treatment of brachial plexus root avulsion injury. Selection of the whole root or the posterior division as neurotizer and a staged operation are the major factors influencing treatment outcome.
