The rats were exposed to 20Gy of X-ray one time systemically to imitate the model of AIRS. By using immunocytochemistry, immunoelectromicroscopy and microspectrophotometry (MSP) technique , the changes of rat thyroid gland C cells in AIRS were investigated. The results show that, the changes of C cells could be divided into two phases. In the first phase (the first 24 h after irradiation) , no obvious morphological change could be observed, whereas the concentration of serum calcium (CSC) dropped remarkably. It seems that the synthesis and secretion of calcilonin (CT) within C cells might increase during this period. The second phase is from 24th h to 72th h after irradiation, the TA (total absorbance) measured by MSP reduced. and the ultrastructural pictures showed progressive destructive changes. All these findings suggest that: The C cells of rat thyroid gland, as a kind of APUD system cell, is no doubt involved in the AIRS pathological changes. The possible pathogenic mechanism was briefly discussed.

Objective To observe the therapeutic effect of hydrogel dressing for alprostadil-induced phlebitis. Methods Forty-three patients with alprostadil-induced phlebitis were randomly divided into two groups:the treatment group (n= 22),in which hydrogel dressing was applied to affected area,and control group(n = 21),in which mucopolysaccharide polysulfate cream was used to coat the surface of the skin. The curative effects were observed and compared between the two groups. Results The therapy effect on day 7 was superior to that on day 3 in both groups.The curative rate was 86.36% in the treatment group and 47.62% in the control group(P<0.05). Conclusion Hydrogel dressing can effectively treat alprostadil-induced by phlebitis.

The overactive bladder syndrome (OAB) is a prevalent condition among adults. Currently, the present treatment is mainly conservative therapy. Antimuscarinic drugs are currently the first-line treatment for OAB. However, many patients experienced insufficient therapeutic benefit and/or unpleasant side effects. Recent advances in the understand-ing of the physiopathology of OAB have driven a huge amount of basic and clinical research into novel pharmacological com-pounds.β3-adrenoceptor agonists are an emerging drug class for the treatment of the OAB. This study reviewed the pharma-cological profile ofβ3-adrenoceptor agonists and discussed the efficacy, safety and tolerability.

Objective To understand the status quo and demanding of resident pension service in Chongqing urban communities to provide the reference for constructing the community pension service system.Methods The questionnaire survey was conducted on 1 080 residents aged 50 years old or older in the nine districts of Chongqing City.Results 89.1％ of the respondents didn't have any pension service,but the currently facing maximal difficulty Was the low proportion of medicare reimbursement,the main service that the elderly wanted to get was life care,security safeguards services and ordinary medical help;73.4％ of the respondents were willing to try the integrated pension service model.Conclusion The government or related departments should optimize new pension resources,increase the funding sources,make reasonable overall planning and construct the pension service model.

Objective To investigate the role of contrast-enhanced ultrasound (CEUS) on the diagnostic efficacy of ultrasound-guided percutaneous biopsy of peripheral lung lesions. Methods Ninty-six patients with pleural-based lesions underwent percutaneous ultrasound-guided biopsy. Of the 96 patients,54patients underwent CEUS before biopsy and enhancement information was referred for the selecting of tissue sampling site. The rest of 42 patients didn' t undergo CEUS before biopsy. The difference in the diagnostic accuracy between the two groups was analyzed to evaluate the value of CEUS before biopsy.Results Of the 52 patients in the CEUS group,48 were malignant,and 6 were benign. Of the 42 patients in the un-CEUS group,36 were malignant, and 6 were benign. Necrosis (areas lacking of enhancement) was demonstrated in 41.7％ (20/48) of the patients with malignant lesions in CEUS group, and necrosis incidence was increased with the increase of the dimension of the malignant lesions. No necrosis area was demonstrated in 6 benign lesions. The rate of successful initial biopsy in CEUS group (98.1 ％ ,53/54) was statistically higher than that in un-CEUS group ( 85.7％, 36/42 ) ( P ＜ 0.05 ). Tissue necrosis and denaturalization attributed to most of the inconclusive pathologic diagnosis. Conclusions CEUS before transthoracic peripheral lung lesion biopsy improved the diagnostic accuracy of the procedure by providing information for differentiating viable or necrotic tissue and consequently provide more accurate information about the site of biopsy.

Objective To explore the influence of combination of Chinese traditional and western medicine continuing nursing care on treatment outcome and quality of life of patients with chronic urticaria.Methods 96 confirmed chronic urticaria patients were selected and divided into the control group and the observation group with 48 patients in each group according to random digit table.The control group was given with routine nursing mode.The observation group received combination of Chinese traditional and western medicine continuing nursing care.The treatment lasted for 12 months.Treatment effect and Dermatology Life Qudity Index (DLQI) evaluation were executed at the end of the 3rd,6th and 12th months.The relapse was inquired 2 months after the intervention by follow-up.Results The total effective rates in the control group and the observation group at the end of the 3rd,6th and 12th months were 75.6％ (34/45),80.0％ (36/45),82.2％ (37/45) and 87.0％ (40/46),91.3％ (42/46),93.5％ (43/46),the results showed significant difference,P ＜ 0.05.DLQI scores at the end of the 3rd,6th and 12th months in the control group and the observation group were (7.82±1.95),(7.04±1.58),(6.56±0.88) scores and (6.85±1.56),(5.71±1.03),(3.42±0.78) scores,the differences were significant,P＜0.05.The relapse interval time was (24.75±5.07) days and (38.20±7.22) days,the difference was statistically significant (P＜0.01).Conclusions Combination of Chinese traditional and western medicine continuing nursing care can significantly improve treatment outcome of chronic urticaria,reduce relapse rate,increase quality of life for patients with chronic urticaria,and it is better than routine nursing care and is worthy of being popularized.
