ObjectiveTo evaluate the influence of different surgical technique on the pup and　adult rats after the rupture of upper trunk and middle trunk so as to find the best way of surgical therapy.MethodsFrom January 2010 to June of 2010, forty-eight Sprague-Dawley male rats were divided into two　groups of 24 each, i.e., pup groups at the age of 7 days postnatal (P7)and one adult (3 months old)group.After C5-7 injured,each group was subdivided into three equally:group A (repair C5-7),B(repair C5,6),and C (no reinnervation performed).In the 3rd month postoperatively,the following tests were performed to estimate the recovery of each group:(1)Compared the rate of carpoptosis of each group.(2)Compared the regenerated nerve traversing rate of the radial nerve in each group.(3)HE stain to compared the cross-sectional area recovery rate.(4)The MyoD1 and Myogenin of the affected extensor of forearm were measured by Western blot.Results(1) The ethology test:there were no carpoptosis in group of adult A and pup A; the carpoptosis rate of pup B and pup C were higher than that of adult A(P ＜ 0.05) ;the carpoptosis rate of pup A was lower than that of B and C(P ＜ 0.05); there was no difference between carpoptosis rate of adult A and B,but they were both lower than C(P ＜ 0.05).(2) Histological test of radial nerves:The percentage of myelinated both higher than C (P ＜ 0.05).(3) Western blot:The protein level of MyoD1 and Myogenin in radial nerve fiber in experimental side of pup A,B and C descended progressively (P ＜ 0.05).There was no difference between adult A and B,but they were both higher than C (P ＜ 0.05).(4) Histological test of the extensor digitorium:There was no difference between cross-sectional area recovery rate of adult A and B,but they were pup A,B and C increased progressively (P ＜ 0.05).There was no difference between protein level of MyoD1 and Myogenin in adult A and B,but they were both lower than C (P ＜ 0.05),ConclusionIn adult rats, there is no difference between the recovery of wrist extensor of the two surgical procedure after the C5-7 injured. The restoration of C5-7 but not C5,6 can do more good to the recovery of wrist extensor in pup rats.It's important to repaire the C7 by nerve graft after injury of C5-7 in newborn.

Objective To investigate the clinical efficacy and safety of total thyroidectomy combined with 131Ⅰradioiodine therapy for patients with hurthle cell thyroid cancer(HCT). Methods From January 2001 to January 2013,20 HCT patients in our hospital,who under-went total thyroidectomy combined with 131Ⅰradioiodine therapy. The complications, the thyroid dysfunction and tumor recurrence were ob-served. Results The total efficiency of patients received total thyroidectomy combined with 131Ⅰradioiodine therapy was 100%, with no hoarseness,infection and other complications. And there was no tumor recurrence or death during follow-up. Total thyroidectomy combined with central lymphadenectomy had increased the chance of injury of parathyroid. There was no significant differences of PTH levels between simple thyroidectomy and total thyroidectomy combined with central lymphadenectomy in patients with different stages of treatment in 131Ⅰtreatment (P>0. 05). Conclusion Simple thyroidectomy combined with 131Ⅰradioiodine therapy causes less chance of injury of parathy-roid that restored within a month, which is high safety.

With the development of society and the improvement of people's living standards, the effect of Chinese medicine in treatment and health care is more and more prominent. The herbal decoction pieces are the important part of Chinese medicine,it can be applied directly to clinical treatment and it's also the raw material of Chinese patent medicine. Therefore, the quality of herbal decoction pieces is quite important. The parts of the production of herbal decoction pieces are numerous, and there are possibilities of adverse effects on the quality of the herbal decoction pieces in every part. In this paper, we based on the production chain of herbal decoction pieces, analyzed the main problem that affect the quality of herbal decoction pieces in the part of selection of Chinese herbal medicines, planting, purchasing, processing, packaging, storage and transport, such as the poor quality of seed and seedlings of plant-based Chinese medicines, some plants left their place of origin and have been introduced in the place that is not suitable for this kind of plant, the insufficient growth time and the excessive harmful substances. The purchasers and the accepters lack of professional knowledge and professional ethics. The mechanism of processing is not clear, the standards can not be uniformed, and lack of qualified person in processing, etc. So we suggest: intensify the basic research of key scientific issues. Improve the quality of persons who work in herbal decoction pieces; Establish an "integration" mode of operation in herbal decoction pieces enterprise; Breeding high quality plant resources, establish the large-scale planting basement; Make the packing of herbal decoction pieces standard; Establish the modernization traditional Chinese medicine logistics enterprise.

Diabetic nephropathy (DN) is one of the chronic diabetic complications,which often leads to chronic renal failure.The diagnosis of DN involves a comprehensive assessment of clinical,pathological and other manifestations.Early diagnosis is rather important for the prevention of DN.

Objective To investigate the formation mechanism of string beads sign in peripheral small cell lung cancer (SCLC) and evaluate the significance of it in differential diagnosis among SCLC,peripheral lung adenocarcinoma and peripheral lung squa-mous cell carcinoma.Methods 78 cases of SCLC,69 cases of peripheral lung adenocarcinoma and 33 cases of peripheral lung squa-mous cell carcinoma,confirmed pathologically were included in this study.The positive rates of string beads sign,mediastinal lymph node metastasis and mediastinal lymph nodes larger than primary lung lesions were calculated and analyzed in these three groups.Results 10 out of SCLC cases (12.8%)have string beads sign,in which all mediastinal lymph nodes were larger than lung lesions.Mediasti-nal lymph node metastases were observed in 63(80.8%)of 78 cases,and 42 (53.8%)cases had larger mediastinal lymph nodes than lung lesions.No string beads sign was observed in patients with peripheral solid lung adenocarcinomas,but 25 of 69 cases (36.2%) have mediastinal lymph node metastasis and 2 cases (2.9%)had larger mediastinal lymph nodes than lung lesions.13 cases(39.4%) of 33 patients with peripheral lung squamous cell carcinomas had mediastinal lymph node metastasis,and 6 cases (16.7%)had larger mediastinal lymph nodes than lung lesions.The statistical results showed the positive rate of string beads sign was not significantly different between peripheral SCLC group and peripheral lung squamous cell carcinoma group,but that of mediastinal lymph node and larger mediastinal lymph nodes than lung lesions were statistically different among these three groups.Conclusion To some extent, string beads sign on CT could reflect the biologic character of SCLC.It played an important role in differential diagnosis of peripheral SCLC,peripheral lung adenocarcinoma and periph-eral lung squamous cell carcinoma,but it should be combined with mediastinal lymph node size.
