Objective　To evaluate the role of transvaginal sonography in diagnosing the normal cervix and its benign lesions.Methods　The one handred and thirty-eight women without malignant findings by colposcopy examination underwent transvaginal sonography within 2 weeks before hyterectomy. The sonography findings were compared with the pathology report.Results　Cervical cysts(39 cases) were the most common sonography findings. In 17 cases, endocervical polyps were found sonographically,in 14 cases, myomas were found,and in 27 cases cervicitis were found. The cervix showed no sonographic abnormal in 41. Pathologic results showed 42 cervical cysts, 14 cervical polyps, 16 myomas, 17 cervicitis and 49 normal cervices.Conclusions　The sensitivity and specificity of transviginal sonography are high in diagnosing normal cervices and benign cervical lessions. Transviginal sonography provides reliable diagnosing information about the cervix for clinic.

AIM: To investigate the effect of exercise training(EX) on the arterial baroreflex and possible mechanisms in rats with chronic heart failure(CHF).METHODS: Experiments were carried out in four groups: EX-CHF,CHF,EX-sham,and sham. CHF was induced by left coronary artery ligation,and EX consisted of 4 weeks of treadmill running. Baroreflex function,plasma angiotensin II(Ang II) and central AT1 receptor expression were determined.RESULTS: (1) The average slope and maximal gain of the baroreflex curve in CHF rats were lower than those in sham rats(P<0.01). EX significantly enhanced baroreflex parameters in CHF group but not in sham group.(2) EX decreased plasma Ang II in CHF rats ［(137±27)ng/L vs (263±55)ng/L,P<0.01］,but had no significant effect on plasma Ang II in sham rats ［(75±17)ng/L vs (92±21)ng/L］.(3) Expression of AT1R protein in the PVN of CHF rats was higher than that in sham rats(1.20±0.21 vs 0.70±0.14,P<0.01). EX reduced AT1R protein level in CHF rats(0.90±0.13),but had no impact in sham rats(0.60±0.16).CONCLUSION: EX restores the attenuated arterial baroreflex function in CHF rats,involving in decrease of plasma Ang II and downregulation of AT1R in the PVN.

To evaluate the effect of problem-based learning (PBL) in internal medicine teaching for residency training of general medicine.Fifty two residents of general medicine were divided randomly into PBL teaching and traditional teaching groups with 26 in each.The evaluation was conducted in combination of examination scores and questionnaire survey in both groups.In questionnaire survey the residents of PBL group responded positively about the use of PBL in teaching, and rated themselves as having much better competencies in problem solving and self-directed learning.The scores of case analysis examination in PBL group were higher than those in traditional teaching group ( 73.7 ± 4.1 vs.71.1 ± 4.8, P ＜ 0.05 ).The results suggest that the application of PBL has better effect than traditional teaching in residency training of general medicine.

Objective To study the clinical value of procalcitonon (PCT) for predicting development of acute kidney injury and outcomes in patients with acute pancreatitis (AP). Methods 205 inpatients with acute pancreatitis in our hospital were enrolled in our study during January 2012 to March 2013. According to acute kidney injury (AKI) occurred in three consecutive days or not, the patients were divided into AKI group (n = 32) and control group (n=173). Crea, Urea, CysC and PCT, serum amyloid A (SAA), interleukin-6 (IL-6) and C reactive protein (CRP) were analyzed. The predictive validity of these indicators was constructed by receiver operating characteristics (ROC) curve. Results PCT, IL-6, and CRP level of AKI group showed significant higher in AKI group than control group (P<0.05). However, there were no statistically significant difference of the level of Urea, Crea, Cys C and SAA between the two groups (P>0.05). The AUC value of PCT showed significant higher than the AUC value of CRP, IL-6 and SAA(P<0.05). Conclusion PCT is a early, sensitive, specific biomarker for predicting AKI of patients with AP.

Objective To analyze testing results and values of blood heterotypic lymphocyte in flu patients.Methods 100 cases of influenza patients and 100 healthy people were collected.The observation group for flu patients and control group of healthy people.Extraction of peripheral blood in patients with microscopic examination observing leukocyte,neutrophil,lymphocyte,intermediate cells,atypical lymphocytes under a microscope,and calculated the percentage in the patients in the two group cells to make analysis and comparison.Ratio in peripheral blood of patients and analysis of specific lymphocytes were also calculated between different ages.Results Peripheral blood lymphocytes in observation group was (11.1 ± 2.6) ％,which was significantly higher than than of the control group [(1.5 ± 0.5) ％].The difference was statistically significant (chi-square =16.9,P ＜ 0.05) ; White blood cells,the ratio of neutrophils,lymphocytes in observation group were obvious differenent compared with the control group(t/chi square are:13.2,11.3 and 12.6,P ＜ 0.05) ;Three ages of influenza patients peripheral blood lymphocytes of the opposite sex ratio has no difference(P ＞ 0.05).Conclusion Detection of peripheral blood lymphocyte heterosexual has great significance to the diagnosis of influenza with simple,convenient and feasible characters.It is worth to be used widely in clinical practice.

Objective: To evaluate the operational efficiency of the division-level hospitals of Xinjiang Production and Construction Corps. Methods: Use DEA’s CCR model and BCC model to calculate the overall efficiency, pure technical efficiency and scale efficiency of Xinjiang Production and Construction Corps, and use super-efficiency model to calculate efficiency ranking of the division-level hospitals. Results: In the total pattern, there were 28.6%of the agricultural division hospitals at the stage of constant returns scale;in the medical service model, there were only 14.3% hospitals at that stage. Conclusion: From the results of two models, the technical efficiency has more room for improvement, compared with efficiency scale. The hospital needs to improve the level of health care technique, avoid blind expansion, minimize unnecessary input, strengthen internal meticulous management, and improve the overall operating efficiency of the hospital.

Leptomeningeal metastasis (LM),with a high omission rate in diagnosis in approximately 5 ％～8 ％ of all patients, is increasingly recognized as a lethality complication. The diagnosis of LM remains challenges,but commonly can be established by CSF cytology or by definitive neuroimaging. Although a combination of focal radiotherapy,intrathecal chemotherapy,and systemic chemotherapy may be necessary to achieve optimal treatment of patients, but prognosis is unacceptable and therapy remains palliative in most patients.
