[Objective]To analyze the clinical and biological characteristics of suspected malignant thyroid nodules associated with Hashimoto thyroiditis .To summarize different characteristics of benign and malignant nodules,diagnosis and treatment of suspected malignant nodules associated with Hashimoto's thy-roiditis. [Methods]Surgical y and pathological y confirmed, 58 cases of suspected malignant thyroid nodules associated with Hashimoto's thyroiditis were retro-spectively analyzed with clinical and pathological data. The differences of gender, age, number of nodules, calcification, and thyroid hormone and thyroid an-tibodies levels between malignant and benign nodules were compared from January 2009 to December 2011 .[Results] The average age of malignant thyroid nodules coexisting with HT group was significantly lower than that of benign nodules coexisting with HT group( P<0.05). The proportion of nodular calcifi-cation in malignant thyroid nodules coexisting with HT group was significantly higher than that in benign nodules coexisting with HT group( P<0.05). Pre-operative TSH and anti-TG levels in malignant thyroid nodules coexisting with HT group were significantly higher than that in benign nodules coexisting with HT group. Preoperative FT3, FT4, anti-TPO levels, sex ratio and number of lesions between the two groups were not statistical y significant. [Conclu-sions] The key point of preoperative diagnosis:patients of malignant thyroid nodules coexisting with HT are associated with youth, calcified nodules, elevated serum TSH and anti-TG levels.

AIM:To analyze the effect 17?-estradiol on activated macrophages and possibility of being a target of screening drugs for endometriosis. METHODS: Using scanning electron microscope, the surface of macrophages was observed. Nitric oxide (NO) in supernatant was determined by Griess's reagent. TNF-? was measured by MTT via L929 cells. Using Fluo-3/AM, i was measured by laser scanning confocal microscopy (LSCM). RESULTS: (1) Increased size, extension of more microvilli, expression of retraction fibers and elaboration of membrane ruffles were detected in 17?-estradiol treated macrophages. (2) 17?-estradiol induced NO release from peritoneal macrophages. (3)The more TNF-? was made by macrophages under the induction of 17?-estradiol. (4)Intracellular Ca 2+ elevated 39.8% in peritoneal macrophages after 17?-estradiol (100 nmol/L) treatment. CONCLUSIONS: Macrophages were activated by 17?-estradiol at a certain concentration. Activated macrophages by 17?-estradiol may participate in endometriosis and may be a target of screening drugs for endometriosis.

Objective: To observe the effect of DSP on three models of memory dysfunction,so as to provide evidence for its potential therapeuticaction for senile dementia.Methods: Three kinds of memory dysfunction are induced by scopolamine,reserpine and ovariectomy respectively,and memory ability is measured through step through and water maze tests.Meanwhile AchE activity in front cortex, hippocampus,striatum and limlic lobe of rats injected scopalamine is determined.Results: DSP can significantly prolong the step through latency,and decrease AchE activity in different parts of rats injeted scopalamine.And DSP can remarkably prolong latency,and increase uterus index of mice after ovariectomy.On the other hand,DSP can shorten water maze latency,enhance the correction percentage of mice injected reserpine.Conclusions:DSP can improve the memory dysfunction possibly through below pathways:(1)enhance the cholinergic system;(2)antagonize the decrease of monoamino transmitter;(3)has the possible estrogen like action.

Objective To study the ability of human embryonic stem cells to integrate into mouse liver and to repair chronic liver injury of the recipient.Methods On day 1,day-7 and day-15 after human embryonic stem cells were induced to differentiate into hepatocyte-like cells and were transplanted into mice with chronic liver failure,liver histopathology,liver function,liver tissue regeneration and mature hepatocytes of mice were tested respectively.Results Hepatic tissue pathology of mice significantly improved after transplantation and necrotic foci diminished,hemorrhage and congestion of hepatic cells relieved,and liver function improved.It was observed that human embryonic stem cells survived,proliferated,integrated with host liver,and differentiated into mature hepatocytes.Conclusions Human embryonic stem cells xenotransplanted into mice can participated liver tissue regeneration to some extent,and differentiated into functional liver cells.

Objective To investigate the associated risk factors of postoperative complications after rad?ical resecting of colorectal cancer. Methods The clinical data of 237 patients with colorectal cancer performed radical resection in the Second Affiliated Hospital of Kunming Medical University from January 2011 to Decem?ber 2014 were analyzed retrospectively. The incidence of postoperative complications was analyzed,and the relat?ed factors were analyzed by single factor and multi factor correlation analysis. Results The postoperative com?plications occurred in 114 cases of 237 patients( 48. 1%) . Univariate analysis showed that the age more than 70 years old,preoperative comorbidity,intraoperative blood loss,surgeon’ s experience,combined evisceration or en?larged evisceration were related to postoperative complications ( P = 0. 033, 0. 014, 0. 045, 0. 028, 0. 040 ) . Compared with the patients without complications,the postoperative anal exhaust time,length of stay was longer of the patients with complications((3. 7±1. 6) d vs. (3. 2±1. 4) d,P=0. 035;(21. 3±6. 5) d vs. (12. 1 ±2. 4) d,P=0. 001). Logistic regression analysis showed that depth of tumor invasion(P=0. 001),preoperative comorbidity including NRS>3 points (χ2 =8. 903, P=0. 003 ) , anemia and hypoproteinemia (χ2 =3. 494, P=0. 048) ,hypertension complicated with type 2 diabetes mellitus(χ2=5. 418,P=0. 026) ,not complete intesti?nal obstruction(χ2=8. 376,P=0. 003),mild and severe ventilation dysfunction(χ2=6. 331,P=0. 011) and WBC<3. 9×109(χ2=4. 256,P=0. 041) were closely related to the occurrence of complications. The rate of post?operative complication of laparoscopic group and open group had no significant difference( 44. 4%( 64/144) vs. 47. 3%(44/93),P>0. 05) . Conclusion Age>70 years old,preoperative comorbidity,intraoperative blood loss,surgeon`s experience,combined evisceration or enlarged evisceration are main risk factors for patients per?formed colorectal cancer radical resection,but laparoscopy?assisted radical resection is not the risk factor.

Objective To study the effects of community comprehensive intervention model on osteoporosis, in order to provides a reference for osteoporosis health education work. Methods A multistage stratified random cluster sampling was applied to conduct a survey in Jiangsu province, in accordance with the economic level and geographic location. Nanjing, Nantong and Xuzhou cities were sampled, three urban streets were sampled in every district , respectively. A total of 1 500 40-69 years old community residents were screened, 619 high-risk participants for osteoporosis were arranged into the intervention group, and a total of 590 residents from the same communities were chosen as control group, who were gender- and age-matched with the intervention group. The intervention group residents received health management and comprehensive intervention, after half a year, a self-designed questionnaire was used to investigate the effects. Results Compared with control group, after six months, knowledge of intervention group related to osteoporosis awareness was improved significantly, such as the most serious harm to human body for osteoporosis (χ2=24.27), characteristic of osteoporosis (χ2=11.05), basic supplements to improve bone health (χ2=60.65) , the recommended daily calcium intake to postmenopausal women and the elderly (χ2=26.80), the difference was statistically significant (P<0.05); daily behavior related to diet and exercise of intervention group has improved significantly, such as drinking milk or itsproducts less than 3 days a week (χ2=25.83), eating beans and products for less than 3 days a week (χ2=19.20), drinking coffee for more than three days a week (χ2=7.77), not often taking outdoor activities (χ2=18.55) ,(P<0.05);Diseases and symptoms related to osteoporosis in intervention group was significantly reduced (P<0.001). Conclusions The osteoporosis is one of the most important public health problem for Jiangsu province, the work for osteoporosis prevention and control should be emphasized in community.

Objective To observe the anti-inflammatory and analgesic effects of CNZ,an optimized prescrition of Liushen Wan based on our previous studies,so as to provide some pharmacological evidence for its further clinical use. Methods Both acetic-acid-induced increased mouse vascular permeability and carrageenan-induced mouse footpad edema were used to study the anti-inflammatory activity of CNZ.Meanwhile,its analgesic activity was evaluated in mice model of pain induced by thermal stimulus and acetic acid.The above activities were compared with those of Liushen Wan.Results CNZ significantly reduced acetic-acid-induced dye leakage at the doses of 16,32 and 64mg/kg after single oral administration.Meanwhile,CNZ at the two higher doses also markedly inhibited carrageenan-induced foot- pad edema,which exerted the strongest effect at 3 hours after carrageenan injection,and lasted over 5 hours.On the other hand,CNZ remarkably suppressed acetic-acid-induced writhing response at low,moderate-and high-doses, and significantly prolonged pain threshold in hot plate assay at moderate-and high-doses 0.5 hour after oral adminis- tration,lasting over 3 hours.Overall,its potency was similar to that of Liushen Wan.Conclusion CNZ has significant anti-inflammatory and analgesic activities.

The present study was performed to investigate competitive interaction between arenobufagin and verapamil hydrochloride with serum albumin.

Objective To evaluate the results of hybrid procedure in treating infants and children with severe pulmonary stenosis (PS) and the clinic value of echocardiography in the whole procedure.Methods Hybrid therapy was performed in 43 patients [(7.1±6.8)months,ranging 5 days to 33 months] with severe PS.The echocardiography data in the whole procedure and follow up were reviewed.Results Aided by echocardiography,the hybrid therapy was successful in 43 cases without major complication.Immediately following valvuloplasty,the gradient across pulmonary valve decreased from (92.5±21.4)mm Hg to (23.6±13.0)mm Hg (P<0.05).The growth and development of 27 patients in follow-up study was well.No restenosis was found and tricuspid regurgitation decreased differently.Conclusions Hybrid procedure is effective and safe for the treatment of infants and children with severe PS.And echocardiography play an important role in the whole procedure.
