Objective To analyze the predictive factors of fever after percutaneous renal stone surgery,and to provide reference for clinical treatment.Methods A total of 147 patients underwent percutaneous nephrolithotomy in after operation was chosen in the Department of Urology in our hospital from January 2014 to January 2016.According to the existence of fever,patients were divided into fever (n =25,heating rate 17.0％) and control (n =122) groups.Preoperative information were collected,including age,gender,preoperative serum creatinine,stone size and shape,the involvement of calyceal number,water,urine culture results,operative time,blood loss,intraoperative perfusion volume,pyonephrosis,puncture channel length,hospitalization time and other information including intraoperative,postoperative information including fever,and postoperative renal fistula complications if there is information.SPSS 18.0 was used for statistical analysis.Results The fever group stone surface area,CT value affected calyx number,stone shape,stone properties,the involvement of calyceal number,degree of hydronephrosis,operative time,intraoperative blood loss,intraoperative perfusion,hospitalization time,and renal fistula complication rates were higher than the control group (P ＜ 0.05).There were no significant differences between two groups (P ＞0.05).The results of Logistic regression analysis found that the stone surface area (OR =5.19),stone,stone shape (OR =7.86) properties (OR =3.87),operation time (OR =5.68),intraoperative perfusion (OR =5.24),and renal fistula complications (OR =2.65) for the influence factors of fever.Conclusions The stone surface area is large,stone nature infection stones,stone shape for staghorn calculi,longer operation time,and intraoperative perfusion of large renal fistula complications were more prone to postoperative fever in postoperative.

AIM: To investigate the effects of in situ transplantation of mobilized autologous bone marrow stem cells on infarction size and cardiac function in patients with acute myocardial infarction. METHODS:25 patients with first acute myocardial infarction were randomly divided into stem cells in situ transplantation group and control group, 12 patients in stem cells in situ transplantation group were injected subcutaneously with 300 ?g granulocyte colony-stimulating factor(G-CSF) daily for four days in addition to standard therapy. 13 patients in control group were treated with standard therapy alone. The conventional 12 leads electrocardiogram were recorded on 1, 28 days after admission and the cardiac function was scored by the QRS scoring system proposed by Wagner. Furthermore, the infarction size was assessed by radionuclide myocardial perfusion imaging 7, 28 days after admission. RESULTS:4 weeks after admission, the QRS scores decreased, the infarction size reduced significantly in the stem cells in situ transplantation group (from 36.0%?8.3% to 18.0%?5.8%, P

AIM: The purpose of this study was to observe the morphological features of neuroendocrine cells(NECs),their proliferation and apoptosis in ovarian epithelial tumors,and to discuss their biological and clinical significance.METHODS: 79 specimens of ovarian epithelial tumor samples were collected,of them 20 benign,18 boderline,41 milignant tumors,and 22 normal ovaries were investigated immunohistochemically.Chromogranin A was used to detect NECs and their proliferation and apoptosis were examined by double-label staining of chromogranin A and Ki67 or TUNEL.RESULTS: The positive rate of CgA,distribution and staining intensity in ovarian epithelial tumors were higher than those in normal ovary.NECs showed various shapes with neuronoid protuberances stretching to the neighboring cells or basement membrane.Occasionally,they might touch together.No TUNEL positive coexpression in all NECs was observed by double-label staining,but some NECs were coexpressed with Ki67.CONCLUSION: NECs of ovarian epithelial tumors like cancer cells showed a proliferation,but no apoptosis.Their secretion might promote their neighboring non-NECs to proliferate and prevent them from apoptosis.

Objective To observe the effects of modified Jianpi Yishen Decoction on urinary osteopontin (OPN) in calcium oxalate nephrolithiasis patients after percutaneous nephrolithotomy (PCNL) or ureteroscope lithotomy (URL);To clarify the mechanism of modified Jianpi Yishen Decoction on the prevention of calcium oxalate kidney stones. Methods Totally 116 calcium oxalate nephrolithiasis patients were randomly divided into trial group (62 cases) and control group (54 cases). The trial group took modified Jianpi Yishen Decoction every other day, while the control group took potassium sodium hydrogen citrate granules three times a day. The concentrations of OPN, urinary calcium and urinary oxalic acid of the patients in the two groups were observed before treatment and 2 weeks and 4 weeks of treatment. Results The concentration of urinary OPN of 2 weeks and 4 weeks of the treatment in the trial group was significantly increased compared with before treatment (P<0.05), and the difference was statistically significant compared with the control group (P<0.05). The concentration of urinary OPN in the control group had no significant change after treatment (P>0.05). The differences in the concentrations of urinary calcium and urinary oxalic acid of the two groups between before and after treatment were not significant (P>0.05). Conclusion Modified Jianpi Yishen Decoction can effectively restrain the formation of the calcium oxalate stones by increasing the level of urinary OPN, which demonstrates effective prevention in the calcium oxalate nephrolithiasis patients after PCNL or URL.

AIM:To investigate effects of thrombopoietin(TPO) and TPOⅡ on human platelet activation in vitro. METHODS:Human platelets were incubated in the phosphate-buffered saline containing rhTPO or TPOⅡ at the concentration of 100 μg/L for five minutes. In order to determine the rate of platelet activation. The CD62P and CD41 expressions on platelets were analysed by flow cytometry using fluorescence labelled monoclonal antibody to CD62P and CD41. RESULTS:The results demonstrated that expression of CD62P on platelets which were incubated with rhTPO or TPOⅡ didn't increase compared with that of contrast group. CONCLUSION:Both rhTPO and TPOⅡdidn't cause the disorder of platelet activation.

AIM: To investigate the biological activity of thrombopoietin Ⅱ(TPOⅡ) in vivo , which consists of two new kinds of ligand binding with thrombopoietin receptor. METHODS: Purified ligandⅠof TPOⅡ, artificial compound ligandⅡ of TPOⅡand rhTPO were injected into purebred Babl/c mice respectively in 7 days by intraperitoneal injection once for a day. Then the biological activity of TPOⅡ was analyzed by measuring peripheral platelet counts by the end of the seventh day. RESULTS: On the seventh day, the platelet counts of mice treated by ligandⅠof TPOⅡ were higher than that in the negative control group( P 0.05). On the fourteenth day, the platelet counts increased in two all experimental groups of TPOⅡcompared with negative control group( P 0.05). Moreover the platelet counts of mice in two experimental groups of TPOⅡ and the positive group showed increase with experimental days. CONCLUSION: The purified ligandⅠof TPOⅡ had obvious activity in increasing platelet production, which is not different from the effect of rhTPO.

Objective To explore the expression of signal-transducing adaptor protein 2 (STAP2) and importin 5 (Ipo5), and the effect of them on skeletal muscle protein turnover. Methods Twelve male Sprague-Dawley rats were divided into control group (n=6) and model group (n=6). The model group established skeletal muscle hypertrophy induced by blood flow restriction. The soleus muscle cells in both groups were cultured in vitro, and those in the model group infected with shRNA lentivirus to make the expression of STAP2 and Ipo5 silencing, over-expression and gene function salvage finally. The expression of STAP2, Ipo5 and myostatin were determined with Western blotting in soleus muscle in both groups.Results The expression of STAP2 increased (t=-11.786, P<0.001), while the expression of Ipo5 and myostatin decreased (t>14.039, P<0.001) in the model groups compared with those in the control group. Under the control group and the model group, and target genes silencing group, overexpressing group and rescuing group, the expression of myostatin increased with STAP2 decrease and Ipo5 increase.Conclusion The expression of STAP2 increasing and Ipo5 decreasing would promote the protein synthesis.

Objective: To estimate the transmission capacity of influenza clustering in schools and nurseries, and to evaluate the effect of suspension measures, providing a basis for formulating disease management strategies and control measures. Methods: The SEIAR dynamics model was used to simulate the epidemic data, calculating the basic regeneration coefficient R 0 of the epidemic to evaluate the epidemic transmission capacity, and calculating the cumulative incidence rate of the epidemic to evaluate the prevention and control effect of the suspension measures. Results: The basic regeneration coefficient R 0 was 8.44(8.01,8.89) without intervention. There were statistically significant differences in R 0 of influenza epidemic among different types of school(F=9.52, P<0.01). The R 0 of influenza epidemic in primary and secondary schools were higher than that in nurseries(P<0.05). R 0 of influenza A was higher than that of influenza B(t=2.71, P<0.01). R 0 of influenza A(H3) was higher than of influenza B(Victoria)(P<0.05). The cumulative incidence of the outbreaks which were suspended for 4 days and 7 days was significantly lower than that in the non-suspensions(P<0.05). However, there was no significant difference in the cumulative incidence of the outbreaks between the 4-day suspension and the 7-day suspension(P>0.05). Conclusion Transmission capacity of school-based influenza epidemic is high, especially among primary and secondary schools. When the epidemic situation of infected class meets the suspension standard, it is recommended to suspend classes for 4 days.
