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.

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.

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.

Background: Chronic hepatitis C is one of the major causes of end-stage liver disease with a high incidence rate, amounting to a grave and serious problem of public health. Currently, interferon-based (with or without ribavirin) antiviral therapy has limited use due to its stringent indications, possible contraindications and side effects. Traditional Chinese medicine (TCM) may have advantages in the prevention and treatment of chronic hepatitis C and it is of significant value to discover the advantages. Through this research, a safe and effective treatment protocol of TCM or integrated TCM and Western medicine for chronic hepatitis C can be formed. To this end, during China's Eleventh Five-Year Plan, special research projects on acquired immune deficiency syndrome (AIDS), viral hepatitis and the other major infectious diseases were established. Our studies on chronic hepatitis C constitute one of the major special research topics. Methods and design: Clinical information of patients with chronic hepatitis C will be first collected in a large, multicenter epidemiological survey. Positive symptoms will be analyzed by rapid cluster analysis, principal constituent analysis and factor analysis, and syndrome types will be diagnosed based on expert advice. Concurrently, a large, multicenter, randomized, parallel-group prospective study will be launched based on evidence-based medical principles to evaluate the effects and safety of the treatment protocol for chronic hepatitis C. The evaluated indexes will include the normalization rate of liver function, virological improvement and quality of life improvement for the short-term efficacy and the incidence of liver cirrhosis and (or) primary liver cancer and mortality for the long-term efficacy. Discussion: This study will investigate the TCM syndrome differentiation norms and the syndrome distribution rules of chronic hepatitis C and evaluate the efficacy and safety of a treatment protocol for chronic hepatitis C based on TCM theory or combined treatment of TCM and Western medicine. The study results will be helpful to developing a TCM treatment program for chronic hepatitis C. Trial registration: The research program was registered in the Chinese Clinical Trial Registry in English and Chinese in January 2010. Registration number: ChiCTR-TRC-10000770.

ObjectiveTo evaluate the effect of lifestyle intervention on high-risk individuals for hypertension. MethodsOne hundred and four prehypertensive adults who received physical examination during October 2005 and October 2007 and showed at least 2 hypertension risk factors were randomly assigned to the experimental or control group.A muhicomponent behavioral intervention,including health education(e.g.awareness of disease),metary gmdance,physical.exercise,and psychologtcat improvement,Was conducted for 2 years.The awareness of disease,blood pressure,bedy weight,and the change of risk factors were compared.ResultsAt 2 years,the awareness of disease in the experimental group wag significantly improved,and the blood pressure,body weight,and risk factors were obviously reduced.Although the awareness of disease and the risk factors in the control group were improved,the blood pressure and body weight were increased.The difference in average systolic blood pressure,average diastolic blood pressure,body weight,and the awareness of disease between the two groups were 13 mm Hg(1 mm Hg=0.133 kPa),7.9 nlnl Hg,3.7 kg,and 37.6%,respectively(all P<0.05).ConclusionThe lifestyle intervention among high-risk individuals for hypertension could effectively reduce blood pressure and body weight. Improved lifestyle would result in less risk factors.

0. 05),cardiac index decreased from 12. 5% to 13. 3 % during hypotension (P 0. 05 ). It was concluded that PaCO2 can still be followed continuously and noninvasively by monitoring end-tidal CO2 tension during hypotension induced by PGE,

Objective To learn about the current situation of nosocomial infections and disinfection and sterilization in some basic medical institutions,then to investigate strategy in regulating the management of nosocomial infections,and to propose the improving measure.Methods With unified questionnaire,the following were investigated:(1)the management,organization and rules and regulations of nosocomial infections and disinfection and sterilization,(2)installation and usage of disinfection armamentaria,and(3)usage and disposal after using of disposable medical products in some basic medical institutions.The data were analyzed statistically by SPSS 13.0 statistics software.Results Some basic medical institutions were deficient in organization,rules and regulations about the management of nosocomial infections,lacked disinfection armamentaria,with disinfectants often used incorrectly.The qualified ratio of the effect of disinfection monitored was low(66.9%).Medical wastes and disposable medical products were disposed of inappropriately.Conclusions To normalize the management of nosocomial infections,training should be reinforced,investment increased and awareness and health supervision enhanced.Meanwhile,air disinfection must be fulfilled more intensively.

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.

0.05),there were more apoptosis-starting cells found in normal skin(1738.33?348.89/mm2)than in keloid(891.67?395.00/mm2)(t=-5.565,P=0.000).The number of positive stained fibroblast cells in dermis significantly increased in keloid group(911.67?323.61/mm2),compared with that in normal skin group(220.00?80.00/mm2)(t=7.188,P=0.000).This result that the protein expression level of Bid was higher in keloid(0.46?0.08)than that in normal skin tissue(0.02?0.01)(t=18.905,P=0.000)was proven by western blotting test.Conclusions The number of apoptosis-starting cells in epidermis of normal skin is more than that in keloid.Bid protein in dermis of keloid is over expressed.
