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 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.

Objective To understand the gray-scale, color and pulsed Doppler sonographic feature of the corpus luteum during the early trimester of pregnancy. Methods The ovaries of 174 patients with intrauterine gestations between 5 to 9 weeks' menstrual age were examined with transvaginal sonography. Size, sonographic appearance, color Doppler feature, resistance index, peak systolic velocity of the corpus letuem were recorded. Results The corpus luteum was identified in 169 of 174 patients(97.1%) . The mean diameter was ( 1.7 ? 0.8 ) cm. The gray-scale appearances were classified into four types:a thin wall cyst(47 patients, 27.8 %), a thick wall simple cyst(45 patients, 26.6 %), a round hypoechoic structure(43 patients, 25.4 %), a thin-walled cyst containing internal debris (34 patients, 20.1 %). Color blood flow was visualized with color Doppler imaging in 92.3 %(156/169). Color Doppler imaging typically revealed a circumferential rim surrounding part or all of the corpus luteum. Low-resistance blood flow was seen with pulsed Doppler, with a mean resistance index of 0.41?0.10 . Conclusions The corpus lutuem in early pregnancy is identified with transvaginal sonography and has different sonographic appearances. It is important to recognize the various appearances of the corpus lutuem to avoidits confusion with true ovarian abnormalities and ectopic pregnancy.

AIM:To determine the effect of reactive oxygen species on the baroreflex and to investigate the intracellular mechanism responsible for baroreflex dysfunction in the heart failure state.METHODS:In the rat model of cardiomyocytes infarct induced heart failure,baroreflex function was evaluated by measuring the relationship between renal sympathetic nerve activity(RSNA)responses and change of blood pressure by intravenous injection of nitroglycerin and phenylephrine.Alteration in baroreflex function was measured under the different reactive oxygen species(ROS)level induced by intracerebroventricular administration of several chemicals.RESULTS:(1)The range of RSNA response,average slope and maximum gain of baroreflex function curve were(92.2?9.9) mmHg,(0.07%?0.01%)/mmHg and(1.20%?0.10%)/mmHg,respectively,in CHF rats,which were significantly lower than those in sham rats(65.6?7.4) mmHg,(0.13%?0.02%)/mmHg and(3.00%? 0.20%)/mmHg(P

Objective To observe the influence of Dunhuang Nourishing Cream on the contents of SOD, GSH-PX and MDA in skin of aged rats. Methods Female SD rats of SPF level were divided into 6 groups:high, moderate and low dose groups of Dunhuang Nourishing Cream, model contrasting group, positive contrasting group and blank contrasting group. After removed the hair on the back, the drug groups were applied with Dunhuang Nourishing Cream, the model group was applied with the matrix of Dunhuang Nourishing Cream and the positive group was applied with vitamin E. After 30 days, the contents of SOD, GSH-PX and MDA in the skin were tested with the method of biochemistry analysis. Results Compared with the model group, the contents of SOD, GSH-PX and MDA in the high, moderate and low dose groups had significant difference (P

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.

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.

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.

Enzyme linked lectin assay (ELLA) and lectin cytochemical staining are employed to study of WGA receptor on human sperm membrane of 44 fertile and 40 unexplained infertile males in this experiment. Binding capacity of sperm from fertile and infertile males, on the average, showed 16.3?10~7 and 9.39?10~7 WGA-HRP molecules per sperm, respectively (P
