People′s misunderstandings about the radiological check in health examination: Equalize the price of the medical check equipment with the accuracy of the check .The health examinees′misunderstanding about the harm which X-Ray can cause , thinking that low dose chest CT only can do very little harm to human body .The health examination unit makes the rate of finding out early lung tumor a main basis of assessing a medical personnel ′s achievement , which caused medical staff go against epidemiological laws when diagnosing tiny nodules .Misun-derstandings about some biological features such as the scale or the growing speed of the nidus , and laying exces-sive importance on the check accuracy , which caused some examinees received excessive X -Ray, overdiagnosis and overtreatment .So, people must treat radiological check in health examination rationally and dialectically , in order to further realize the legitimation and rationalization of radiological check .

A series of medical equipment question is introduced including currency use, combination, digital function and whole efficiency. By using system theory, the thought and viewpoint were put forward that how to solve equipment classification, "three turn" design (generalization, modularization, serialization), informationization alteration and affixation etc. Some thoughs on development strategy of medical equipment and creative information condition of field battle can be referred and provided.

Objective To explore diagnosis and operative treatment of primary cholecy stocarcinoma. Methods One hundred and thirty-six cases of biliary carcinoma were analysed for their clinical and pathological data and selection of the method of operation.Results The prognosis of late-staged cases was very bad.B-US and CT are still the most helpful means for clinical diagnosis.Conclusion The early diagnosis and treatment of primary cholecystocarcinoma are of utmost importance.

Objective To investigate the clinical significance of DHS and LCP in treating elderly patients with intertrochanteric fracture.Methods 58 elderly patients were randomly divided into 2 groups.30 of them( DHS group) were treated with DHS,while 28 cases of them were treated with LCP.Blood loss,operation time,bone healing time and Harris score were analyzed.After 1-year follow time,effective rate and complication rate were also recorded and evaluated in the 2 groups.Results The complication rate in LCP group was lower than that in DHS group(P ＜0.05),while the effective rate and Harris score in LCP were higher than that in DHS group( P ＜0.05 ).There were no significant differences in blood loss,operation time and bone healing time between the 2 groups ( P ＞ 0.05 ).Conclusion Compared with DHS,LCP is effective in treating elderly patients with intertrochanteric fracture.

Allogeneic hematopoietie stem cell transplantation(alloHSCT) is a potentially curative therapy for patients with hematological malignant disease, autoimmune disease or hereditary disease.However, graftversus-host disease (GVHD), which is one of the most serious complications, influences the prognosis of alloHSCT. Mechanisms of GVHD is so complicated that there is still no perfect way to treat the patients at present. Recently, mesenchymal stem cells(MSC) become new hotspots because of their immunomodulatory properties and potential to suppress alloreactive T cell responses.Animal experiments showed that MSC were effective during the prevention and treatment of GVHD. This paper is to summarize the acting mechanism of MSC' effect on the prevention and treatment of GVHD after alloHSCT.

Autism in children is a complex disease of developmental disorder in nervous system,characterized by social deficits,impaired language and communication,stereotyped and repetitive behaviors.Studies indicate oxidative stress is associated with autism.Because of genic and environmental factors,children with autism are susceptible to oxidative stress.Oxidative stress induce the development of autism through abnormal metabolism of the membrane lipid,inflammation and excitotoxicity,autoimmunity,energy metabolism disorder,et al.Anti-oxidation might be a safe and effective therapy for autism.

Objective To understand the distribution characteristics of HIV infection status among the outpatients in this hospi-tal to provide the beneficial supplement for local large-scale survey and the basis especially for the hospital infection control.Meth-ods The HIV screening situation on the outpatients of our hospital from 2007 to 2012 was retrospectively analyzed.Results Dur-ing these 6 years,108 999 specimens were detected,88 cases were positive in the preliminary screening and 81 cases were confirmed positive.The positive rate of anti-HIV antibody was 0.074%.In addition to voluntary counseling and testing,the specimens submit-ted by the outpatient anorectal department and the inpatient hematology department had the higher positive detection rate,which was 1.16% and 0.84% respectively.Conclusion The HIV infection rate in non-infectious disease specialized hospitals shows the increasing trend.The key departments must increase the intensity of the medical staff training,pay attention to early diagnosis of HIV/AIDS,prevent the hospital infection and reduce the risk occurred after the occupation exposure.

Objective To investigate the effect of curative and uterine cervical shaping of different loop electrosurgical excision procedure (LEEP) in treatment of chronic cervicitis.Methods Selected 369 patients with chronic cervicitis,and they were divided into shallow ring excision (SRE) group (123 patients),deep ring excision (DRE) group (123 patients) and LEEP conization (LEEPC) group(123 patients).In each group,they were divided into three subgroups according to the degree and type of erosion.The clinical efficacy of three groups were compared after treatment of 3 months.Results The recovery rate of mild uterine cervical erosion with symptom and midrange uterine cervical erosion,granular pattern uterine cervical erosion and simple uterine cervical erosion among three groups had no significant difference (P ＞ 0.05).In LEEPC group,the recovery rate of severe and mastoid uterine cervical erosion were significantly higher than those in SRE group and DRE group [80.49％ (33/41) vs.63.41％ (26/41) and 58.54％ (24/41),88.24％ (45/51) vs.71.43％ (40/56) and 74.55％ (41/55)] (P ＜ 0.05).The satisfactory rate of uterine cervical shaping among three groups had no significant difference (P ＞ 0.05).Conclusions The three kinds of LEEP have a higher satisfactory rate of uterine cervical shaping.However,different surgical procedure on different level and different type have different efficacy.Clinicians need to choose the right surgery according to the patient's condition.

Objective To study the high-frequency ultrasound features of papillary thyroid microcarcinoma and pathological features.Methods The ultrasonic diagnostic features of 89 cases of papillary thyroid microcarcinoma were analyzed retrospectively,and the ultrasound results and pathological results were compared.Results In this study,high frequency ultrasound examination showed that the thyroid ultrasound diagnosis coincidence rate of papillary microcarcinoma was 94.4％.Patients mainly concentrated in 40 ～ 59 years,8 cases of type Ⅰ blood flow,16 cases of type Ⅱ blood flow,65 cases of Ⅲ blood flow,83 cases of L/T (aspect ratio).Conclusion The different pathological features of papillary thyroid microcarcinoma accompanied with the different ultrasound images.Doppler high frequency ultrasound in the identification and diagnosis of papillary thyroid microcarcinoma is accurate,convenient operation,and low cost,which is worthy of clinical application.
