Objective:To understand the awareness of students of medical colleges sperm behavior, attitudes and prac-tical factors. Methods:Used convenient sampling method to select 300 college students of 4 medical colleges in Shanghai conducted a questionnaire survey and used Epidata 3. 1 and SPSS 18. 0 to count and analyse. Results: 251 question-naires. 39. 8% of respondents were willing to sperm, the primary reason was considered to be an act of charity, helping others;willing sperm donors only distributed among schools statistically significant (P<0. 05) proportions, and for the various professional and grades , showed no significant difference ( P>0 . 05 ) . Conclusion:Students of Shanghai Medical Colleges sperm voluntary rate was not high, so the survey analyzed related factors affecting sperm donation and put forward practical proposals to provide reference data and methods for sperm bank sperm recruiting for volunteers in the universities.

Objective To investigate the effects of peritoneal injection of cobaltic protoporphyrin Ⅸ chloride(CoPP)to induce heme oxygenase-1(Ho-1)upregulation in rat islet cells.Mthods Forty rats were divided into 5 groups by management 24 h before islets isolation:group A received inlzaporitoneal injection with 2.5 ms/ks CoPP,group B with 5 ms/ks CoPP,group C with 7.5 ms/kg CoPP,and group D with 10 mg/kg CoPP.In control group NS was used instead.A modified Goth approach was used for islet isolation.the yield and purity of the islets were assessed.The expression of Ho-1 mRNA and protein were detected by real time-PCR and Western blotting respectively.Islet function was tested by glucose stimulation test.Result Severe damage was found in tlle rats in group C and D.There was no difference in islet yield and purity for group A、B、C and control(P＞0.05).Group B had the highest Ho-1 mRNA and protein expression among the 4 groups.Though there was no difference in insulin secretion by low glucose challenge for group A、B and control's islets(P＞0.05),when challenged by hish level of glucose,significant deviation was observed.The imulin secretion level was(172.37±16.4)、(187.68±19.93)and(91.25±Conclusion Peritoneal iajection of 5 mg/kg CoPP can significantly enhance the expression of Ho-1 mRNA and protein in tat islet safely and enhance the function of islet when challenged by hish concentration of glucose.

Objective To analyze the protection supplied by HSCs in vivo after islet cells homotransplantation. Method Diabetic mice were randomly divided into three groups as diabetic group,islet-transplant group and co-transplant group. 300 islets alone or mixed with HSCs were transplanted under the capsule of the kidney of the diabetic recipients respectively. Blood glucose and the length of normal blood glucose level were recorded and we collected the blood and tissue of islet graft 7 days after transplantation in each group. Blood concentration of TGF-β, TNF-α, IL-1β and IFN-γ were detected by ELISA. The infiltration of lymphocytes was observed by HE staining and immunohistochemieal examination.Result Co-transplant group had a prolonged islet allograft survival for (23.75 ± 8. 96) days, compared with the islet alone of (11.9 ± 6. 92) days. Blood concentration of TGF-β in co-transplant group was (2292.31 ± 5.87) pg/ml, significantly higher than those in simple transplant group (1246.55 ±38.91) pg/ml(P <0.05), there was no differentence in the two groups for TNF-α,IL-1β and IFN-γ.Conclusion HSCs may prolong the islet graft survival by expressing higher level of TGF-β and form a capsule around the graft.

Objective To investigate the application value of extracorporeal extended field radiotherapy in locally advanced cervical cancer. Methods A total of one hundred and twenty patients with stage IIB?IVA cervical cancer in the First Affiliated Hospital of Hebei North University from June 2012 to June 2014 were randomly divided into two groups:the control group and the observation group,each with 60 cases. The routine concurrent chemoradiotherapy was adopted in the control group. The observation group was treated with extracorporeal extended field radiotherapy combined with concurrent chemotherapy. The patients have been followed up for three years. The total efficacy rate,toxicity reaction,local progression free survival time ( PFS) and survival rate of the two groups were compared. Results The total efficacy rate in the observation group was significantly higher than that of the control group ( 88. 3%( 53/60 ) vs. 73. 3%( 44/60 ) , χ2 = 4. 357, P=0. 037),while the incidences of toxicity reaction in the two groups were 18. 3%(11/60) and 16. 7%(10/60), the difference was not statistically significant (χ2=0. 058,P=0. 810) ,the percentages of I and II degree in the two groups were 3. 4%( 2/60 ) and 3. 4%( 2/60 ) , the difference between the two groups was not statistically significant (Z=0. 000,P=1. 000). The PFS value in the observation group was significantly longer than that of the control group ( 25. 6 months vs. 13. 8 months,χ2 = 25. 624, P= 0. 000 ) , and the survival rate in the observation group improved significantly ( 53. 3%( 32/60 ) vs. 33. 3%( 20/60 ) , the difference was statistically significant (χ2 = 4. 887, P= 0. 027 ) . Conclusion Extracorporeal extended field radiotherapy is safe and effective in the treatment of locally advanced cervical cancer.

OBJECTIVETo perform a meta-analysis on clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults.

METHODSPubmed database (from 1968 to March 2014), Cochrane library and CNKI database (from 1998 to March 2014) were searched. Case-control study on minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults were chosen,and postoperative infection, operative time, blood loss, fracture nonunion rate, delayed union,fracture malunion rate were seen as evaluation index for meta analysis. The system review was performed using the method recommended by the Cochrane Collaboration.

RESULTSTotally 5 studies (366 patients) were enrolled. Meta-analysis showed that there were significant meaning in postoperative infection between MIPPO and ORIF [OR = 0.23,95% CI (0.06,0.92), P = 0.04]; fracture nonunion rate in MIPPO was lower than in ORIF group [OR = 0.16, 95% CI (0.03,0.76), P = 0.02]; operative time in MIPPO was shorter than in ORIF group, and had significant difference [MD = -14.42, 95% CI (-27.79, -1.05), P < 0.05]; blood loss in MIPPO was less than in ORIF group [MD= -87.17,95%CI (-99.20, -75.15), P < 0.05]; there was no obviously meaning in delayed union between two groups.

CONCLUSIONFor distal tibial fractures in adults, MIPPO has, advantages of short operative time, less blood loss, lower incidence of infection and fracture non-uniom, but with high fracture malunion rate. MIPPO for distal tibial fractures in adults is better than ORIF, and the best treatment should choose according to patient's condition.

AIMTo investigate the influence of CCE3 on bone mineral element metabolism and relative hormone in ovariectomized rats.

METHODS24 female SD rats were divided randomly into 4 groups (n = 6): (1) Normal control; (2) sham ovariectomy; (3) ovariectomy(OVX); (4) OVX + CCE3.

RESULTS(1) Ca, Mg, S, Co, Mn, Zn reduced obviously and P increased in the bone of the OVX rats. (2) E2, P, TSH, T4, CT, cortisol, GH reduced obviously and IL-6, FSH, LH increased obviously in serum of the OVX rats. (3) CCE3 corrected the changes of Ca, Mg, S, Co, Mn, Zn and P in bone as well as the changes of E2, P, TSH, T4, CT, cortisol, GH and IL-6, FSH, LH in serum of the OVX rats.

CONCLUSIONChanges of relative hormone and IL-6 induced by CCE3 are the important mechanism of the influence of CCE3 on bone mineral element metabolism in ovariectomized rats.

OBJECTIVETo observe dynamically the effect of drugs for clearing heat and removing dampness (CHRD) on biliary components in rabbits with pigment gallstones (PGS).

METHODSForty rabbits were established into PGS model and randomly divided into 3 groups, the bacterial infection group, the CHRD low-dose group and the CHRD high-dose group. Besides, a normal group was set up with healthy rabbits for control. Changes of total bilirubin (TB), unconjugated bilirubin (UCB), total bile acid (TBA), Ca2+, bacterial and endogenous beta-glucuronidase (beta-Gase) in bile were observed.

RESULTSCHRD drugs significantly decreased the contents of UCB, Ca2+, bacterial and endogenous beta-Gase (P < 0.05), and increased TBA in bile (P < 0.05).

CONCLUSIONCHRD drugs have good effect in reducing the lithogenesis of the pigment gallstones.
