Objective To study the clinical value of exposure of recurrent laryngeal nerve in thyroid operation for the prevention of recurrent laryngeal nerve injury. Methods A total of 90 patients received thyroid operation in our hospital from April 2012 to August 2014 were enrolled and randomly divided into observation group(n=45) and control group(n=45) according to whether the recurrent laryngeal nerve were exposed during operation. The patients in observation group received thyroid operation with recurrent laryngeal nerve exposure, and the patients in control group received conventional thyroid operation. Then recurrent laryngeal nerve injury situation and operation situa-tion were compared. Results Recurrent laryngeal nerve injury symptoms were less in the observation group (2. 22%) compared with that of the control group (15. 56%) with a statistically singnificant difference(P<0. 05). The operation time of observation group (54. 45 ± 6. 62) min was longer than that of the control group (41. 29 ± 5. 82) min with a statistically singnificant difference (P<0. 05). The recovery time of observation group (5. 85 ± 0. 85) d was shorter than that of the control group (8. 02 ± 1. 12) d, with a statistically singnificant differ-ence (P<0. 05). There was no significant difference in bleeding volume during operation,postoperative drainage volume and drainage dura-tion between two groups(P>0. 05). Conclusion Exposure of recurrent laryngeal nerve in thyroid operation is helpful to prevent recurrent laryngeal nerve injury,which reduce the damage recovery time,although it will extend the operation time,does not increase bleeding and drainage volume.

Through the literature combing the interest groups of hospital information disclosure in the United States, the demand and practice of the main interest groups are analyzed. This paper uses policy maker4. 0 software to further analyze the interests of various interest groups, power and the degree of influence by the policy of hospital information disclosure. The results showed that interest groups involved in hospital information disclosure in the Unit-ed States can be mainly divided into five categories:consumers, employers, health insurance companies, hospitals, and decision makers ( government) . In order to balance the cost-effectiveness of various insurance schemes, health insurance companies choose high-quality service providers to restrict poor-service providers and insurers, and hospi-tals need to use public information to manage and improve health care. In order to monitor and improve the quality of medical services, employers need to weigh various insurance plans, health insurance companies have to measure the service quality of themselves and competitors, and hospitals need to manage and improve the medical quality and in-crease market share. As the largest stake in the hospital information disclosure, the results show that the consumer's position on the hospital information disclosure is low support. From the consumer as a main, although the hospital in-formation disclosure practices but the right to speak and other small powers have a limited participation. Analyzing the of the interest groups of hospital information disclosure in the United States, they all push forward the hospital infor-mation disclosure work to provide evidence to support.

Objective To compare the therapeutic effect in two kinds of inhalation in infant asthmatic bronchitis.Methods Two hundred and twelve asthmatic bronchitis children were randomly divided into group A (103 cases) and group B (109 cases).The children in two groups were treated with conventional therapy,including antibiotics,fluids and other treatment.The children in group A were given budesonide 1 mg,terbutaline 5 mg plus 0.9％ sodium chlorine in 2 ml,with oxygen driven inhalation therapy,2-4 times/d.The children in group B were given albuterol sulfate inhalation aerosol 1-4 spray/times,4-6 times/d,inhaled fluticasone quantitative aerosol spray 1-2 spray/times,2 times/d,15 s/times.The course of two groups was 5-7 d.The therapeutic effect was compared.Results The total effective rate in group A and group B were 92.2 ％ (95/103) and 97.2 ％ (106/109),there was no significant difference (x2 =2.73,P ＞ 0.05).The relieve time of cough,gasping and wheezing,hospital stay in group B were shorter than those in group A [(12.00 ± 2.75) h vs.(29.00 ± 1.25) h,(10.00 ± 1.45) h vs.(31.00 ± 2.75) h,(13.00 ± 1.55) h vs.(33.00 ± 2.33) h,(7.20 ± 0.65) d vs.(8.70 ± 1.35) d],the cost of hospitalization in group B was lower than that in group A [(2.00 ± 0.30) thousand Yuan vs.(2.50 ± 0.55) thousand Yuan],there were significant differences(P ＜ 0.05).Conclusions The albuterol inhalation solution combined with fluticasone has the advantages of rapid efficacy,short course,low cost,easy to accept and adjust.It is worth to spread in primary hospital.

[Objective]To observe the effect of Chinese herbs for activating blood stasis on the shape and function of the endothelial cells in rat aorta.[Method]Rat models of PCOS have been established according to Poresky,randomized into animal model and Chinese medicine group(TCM group),normal rats were control group.Measure the serum level of FSH,LH,T,INS and plasma ET PAI-1,and observe the endothelial cell morph.[Results] In the model group,the endothelia cells of the aorta were contracted,with discontinuous basement membrane,inflated chondriosome,the middle layer smooth muscles tending to move inside and out of the normal shape of intraendothelial junction.In the TCM group,the endothelial cells appeared flat,arranging along the long axis of the blood vessels,normal endothelial cell integrity with scanty cytoplasm and the microscopic appearance shows highly developed golgiosome rough endoplasmic reticulum and smooth endoplasmic reticulum.The model group had a more increased serum level of PAI-I and ET than those of the control group,and showed the significant difference(P0.05).The TCM group had more decreased level of ET than those of the normal group(P

Toll-like-receptors(TLRs) have been found to play a critical role in immune response of hosts.They can trigger innate immune responses by detecting pathogen-associated molecular patterns(PAMPs).This paper reviews the roles of several toll-like receptors(TLR4,TLR5,and TLR9) in radioprotection and the related mechanisms,so as to provide theoretical evidences for further studying their roles in radioprotection.

Rectal cancer is a common malignant tumor in the gastrointestinal system.For the patients with resectable but high-risk rectal cancer,neoadjuvant and adjuvant chemoradiation plus surgery may improve local control.Compared to adjuvant chemoradiation,neoadjuvant chemoradiation showed the advantage of sphincter preservation.When the goal of preoperative chemoradiation was sphincter preservation,conventional radiotherapy was recommended.Through the analysis of the patients with 5-year survivals,the radiation had a similar impact on the survival as the chemotherapy alone for the patients with the intermediate risk factors.The impact on local control need to be further investigated before recommending chemotherapy alone for those subset patients.Advances in preoperative irradiation,postoperative irradiation and the comparison of preoperative irradiation with postoperative irradiation are also reviewed in this article.

Objective: To establish a rapid approach to the detection and identification of Mycobacteria from lesions of patients with suspected Mycobacterial infections. Methods: Specimens were obtained from five patients suspected to have Mycobacterial infections. DNA extracted from clinical samples was amplified by nested PCR. The PCR products were digested with Hha Ⅰ, MboⅠ, and BstUⅠ restriction enzymes and applied to PAGE. The species of Mycobacteria were determined by restriction fragment length polymorphism (RFLP) analysis. Identification of Mycobacteria culture was also performed in 3 patients. Results: M. marinum was found in two patients diagnosed as swimming pool granuloma. M. tuberculosis was found in one patient diagnosed as infectious skin granuloma. All these 3 Mycobacteria were confirmed by Mycobacteria culture. A strain of M. tuberculosis and a strain of M. fortuitum were detected in remain two patients. Conclusion: The results above indicate that PCR-RFLP analysis is rapid and reliable in detection and identification of different Mycobacteria species from skin tissues. Application of this method will be helpful for early diagnosis and treatment of Mycobacteria skin infections.

Congenital hypertrophic pyloric stenosis(CHPS)is a common gastrointestinal congenital mal-formation in neonate and small infants.Pyloromyotomy is an effective method for treatment of CHPS,including several methods.Traditional open pyloromyotomy for the patient's body injury is serious,such as accident of an-esthesia,postoperative infection,skin scar;laparoscopic pyloromyotomy can cause the pylorus muscle incision uncomplete,invasive operation damage,etc.Endoscopic pyloromyotomy for neonatal has some advantages:a lit-tle injury,no scars,simple operation,less complications,quicker recovery of feeding.Endoscopic mucosal pyloro-myotomy may be a new method of treatment,needing further exploration and research.
