Objective To investigate the correlation between sperm-nucleporotein transition and sperm parameters and embryo development,also to evaluate the influence of pregnancy out comes of assisted reproductive technology (ART).Methods Sperm-nucleoprotein transition assay of a total of 676 patients underwent ART treatment were detected by aniline blue staining,and the correlation analysis between spermnucleoprotein transition and sperm parameters,DNA damage,acrosin activity,fertilization rate,cleavage rate,quality of early embryo development as well as blastocyst formation rate was performed.Results The sperm concentration,(a+b) ％ sperm,sperm count and acrosin activity was (66.5±4.6) × 109/L,(149.2±9.9)×109/L,(51.2±1.3)％ and (72.2±3.3) mU/106 sperm in abnormal group,and (91.9±2.7) ×109/L,(240.0±8.0) ×109/L,(57.3±0.8)％ and (85.7±1.9) mU/106 sperm in normal group,which reached significant difference (P＜0.01).DNA fragmentation index (DFI) was (17.3± 1.0)％ in abnormal group,which was significantly higher than (14.6±0.5)％ in normal group.The cleavage rate of 95.0％,D3/D5 high quality embryo rates of 34.2％ and 1.28％,D5 blastocyst formation rate and the total rate of blastocyst formation rate of 22.4％ and 38.6％ in abnormal group,which were significantly lower than that in normal group (96.9％,38.2％,2.70％,27.9％ and 46.4％) (P＜0.01).The rate of spontaneous abortion was 12.3％ in abnormal group,which was significantly higher than that in normal group (4.7％) (P＜0.01).However,there was no significant difference in biochemical pregnancy rate and ectopic pregnancy rate between the 2 groups (P＞0.05).Conclusions Sperm-nucleoprotein transition was positively related with sperm parameters,DNA damage,acrosin activity,and also has an adverse effect on embryo development and the outcomes of ART.It is suggested that the sperm-nucleoprotein transition should be detected before ART.

Objective To investigate effects of hyperbaric oxygen (HBO) therapy on C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) levels in patients with moderate or severe traumatic brain injury (TBI)and to analyze its therapeutic efficacy. Methods One hundred and eight patients with moderate or severe TBI were randomly divided into a control group (54 cases) and an HBO adjunctive therapy group (HBO group, 54 cases).Both groups received essential neurosurgical treatment and conventional drug treatment, and the HBO group was given one session of HBO therapy in addition. Serum CRP and TNF-α were detected, and the scores on the Glasgow coma scale (GCS) were measured before and after treatment. CRP was detected by turbidimetric immunoassay and TNF-α using ELISA. Glasgow outcome scale (GOS) scores were evaluated in a follow-up 6 months after injury. Results Average CRP, TNF-α and GCS measurements showed no statistically significant difference between the groups before treatment. After treatment, CRP and TNF-α were significantly lower and GCS scores significantly better in both groups, but patients in the HBO group were, on average, significantly better than the controls on all three measures.Six months later, GOS evaluation gave a significantly larger number of patients with a better prognosis in the HBO group compared with the controls. Conclusion HBO therapy can significantly decrease serum CRP and TNF-α after severe TBI, thus enhancing therapeutic efficacy.

Objective To evaluate the therapeutic effect of endoscopic management of plastic stents of post-liver transplantation anastomotic biliary stricture. Methods From January 2010 to October 2015, clinical data of patients with post-liver transplantation anastomotic biliary stricture and received endoscopic retrograde cholangiopancreatog﹣raphy and plastic stents management was collected. The technical success rate, ERCP-related complications, clinical remission rate and long-term complications were main outcome measurements to compare the efficacy and safety of different number of stents in managing post-liver transplantation anastomotic biliary stricture. Results Among the 18 patients (0.5 ~ 60.0 months) with post-liver transplantation ABSs, seven patients received less plastic stents treat﹣ment (< 3 stents), nine patients with persistent anastomotic or recurrent stricture received multiple plastic stents treatment (≥ 3 stents), two patients received multiple plastic stents treatment once suffered with post-liver trans﹣plantation ABSs. The endoscopic technical success rate was seventy-six over eighty (95.0 %). Among the seven pa﹣tients received less plastic stents treatment, one loss to follow-up, two were still under treatment, one died of acute hepatic failure, one died of septic stock, one combined with biliary fistula resulted in treatment failure, one achieved clinical remission, the clinical remission rate was one third (33.3 %). Among the eleven patients received multiple plastic stents treatment, two loss to follow-up, one was still under treatment, two received surgery because of failed treatment, six achieved clinical remission, the clinical remission rate was 75.0 % (6/8). The average diameters and stent durations of management of 1 stent, 2 stents, 3 stents, 4 stents, 5 stents, 7 stents were 8.5 F, 17.0 F, 24.0 F, 28.0 F, 36.0 F, 50.0 F. Among the six early postoperative complications, five cases occurred in less stent manage﹣ment and one occurred in MPSs management, the early postoperative complication rate was 7.5 %(6/80). No severe ERCP-related complications and procedure-related deaths. Conclusions Endoscopic management of plastic stents is safe and effective for post-liver transplantation ABSs. Providing larger biliary support, the multiple plastic stents treatment was superior to less plastic stents treatment in view of clinical remission rate, especially for refractory one. Multiple plastic stents did not increase the incidence of complications, it could be used as the first-line treatment of post-liver transplantation duct-to-duct biliary anastomosis for its safety and effectivity.

BACKGROUND: To discuss the feasibility of allogeneic freeze-drying radiation sterilization bone sheet applying in the prevention of post-laminectomy adhesion as an ideal biological material for filling and repairing bone defect. OBJECTIVE: To observe the preventive effect of allogeneic freeze-drying radiation sterilization bone sheet on the postlaminectomy adhesion and restenosis.DESIGN: Follow-up survey on cases.SETTINGS: Department of Orthopedics, Union Hospital, Tongji Medical School of Huazhong University of Science and Technology; Shanxi Medical Tissues of China Institute for Radiation Protection PARTICIPANTS: From March 2003 to June 2005, 58 patients with segmental lumbar spinal stenosis (LSS) were selected from Department of Orthopedics, Union Hospital, Tongji Medical School of Huazhong University of Science and Technology, including 34 males and 24 females, aged 30-78 years, including 25 cases of simple LSS and 33 combined LSS; and including 36 cases in L4-5 and 33 cases in L5, S1 segments. All the patients were similar in age, gender and healthy conditions.METHODS: The segmental whole laminectomies were performed in 58 patients with prolapse of lumbar intervertebral or LSS, and allogeneic freeze-drying radiation sterilization bone sheet in "H" shape was used to cover the vertebral laminae. According to the follow-up standard of lumbar spine operation recommended by the Orthopaedics Branch of Chinese Medical Association, all patients were followed up to evaluate their clinical symptoms, absorption of implanted bone as well as CT and MRI presentations.MAIN OUTCOME MEASURES: Improvements of clinical symptoms;Absorption of bone sheet in lumbar spinal canal.RESULTS: Totally 58 LSS patients were involved in the result analysis.In postoperative 0.5-year follow-up period, 17 of 21 patients showed excellent curative effects while other 4 patients showed fine effects. In postoperative 1-year follow-up period for 23 patients, CT and MRI results demonstrated that the spinal canal had been extended obviously. There was no tilt or displacement of the femoral sheet or compression of the spinal cord. As for 14 patients who were followed up for 1.5 years, CT results displayed that there was no rejective reaction observed in this study. The edgeof the allograft was inosculated with connective lamina of vertebra, and the shape of lumber spinal was good.CONCLUSION: Allogeneic freeze-drying radiation sterilization bone sheet is an ideal dressing material for epidural laminoplasty. The imaging results of patients in postoperative 1.5-year follow-up indicate that it can effectively reduce the post-laminectomy adhesion formation and prevent recurrence of post-laminectomy spinal restenosis, so as to apply on the segmental vertebral plate dressing.

Objective To investigate the effects of hyperbaric oxygen (HBO) therapy on interleukin-1 β( IL-1 β) and interleukin-6 ( IL-6 ) levels in patients with moderate or severe traumatic brain injury ( TBI ) and to analyze its therapeutic efficacy.MethodsOne hundred and fifty-six patients with moderate or severe TBI were randomly divided into a control group and an HBO adjunctive therapy group with 78 cases in each.The control group received essential neurosurgical treatment and conventional drug treatment,and the HBO group was given one HBO therapy session in addition.IL-1 β and IL-6 were quantitatively determined using sandwich ELISA,and the patients'scores on the Glasgow coma scale (GCS) were measured before and after treatment.The Glasgow outcome scale (GOS) was used to evaluate in a follow-up 6 months after injury.ResultsThe average IL-1 β and IL-6 levels of the two groups and their average GCS scores were not significantly different before treatment.After treatment,IL-1 βand IL-6 levels decreased significantly and GCS scores increased significantly in both groups,but there were significant inter-group differences in all three measures.Six months after injury the GOS evaluation indicated that significantly more patients had better outcomes in the HBO group than in the control group. Conclusion Conventional treatment combined with HBO therapy can promote neurofunction recovery in TBI patients.The mechanism may be related to down-regulation of serum IL-1 β and IL-6.

Objective To investigate the role of N-myc downstream regulated genes 2 (NDRG2) in attenuation of focal cerebral ischemic-reperfusin injury by sevoflurane preconditioning in rats.Methods Forty-eight healthy male SD rats weighing 280-320 g were randomly divided into 3 groups ( n =16 each):sham operation group (group S),ischemia-reperfusion injury group (group I/R) and sevoflurane preconditioning group (group Sev).Focal cerebral ischemia-reperfusion injury was induced by right middle cerebral artery occlusion (MCAO)for 120 min followed by 24 h reperfusion.In group Sev,2.0％ sevoflurane was inhaled 1 h once a day for 5 consecutive days at 24 h before MCAO.The neurologic function was evaluated at 24 h of reperfusion and than the rats were sacrificed,and the brain was removed for determination of infarct volume percentage,NDRG2 and activated Caspase-3 expression in ischemic penumbra by Western Blot and NDRG2 expression and location by immunohistochemistry.Results The infarct volume percentage,NDRG2 and activated Caspase-3 expression were higher,and neurologic function score was lower in groups I/R and Sev then in group S( P ＜ 0.05).The infarct volume percentage,NDRG2 and activated Caspase-3 expression were lower,and neurologic function score was higher in group Sev then in group I/R ( P ＜ 0.05).The intranuclear NDRG2 positive staining was decreased in group Sev than in group I/R.Conclusion Sevoflurane preconditioning can reduce focal cerebral ischemia-reperfusion injury by inhibiting the expression and activity of NDRG2 and apoptosis in rats.

Objective: Based on coronary artery calciifcation (CAC) distribution in the rural population of Yunnan province, we further explored the relationship between coronary artery calciifcation score (CACS) and the pulse pressure difference (PPD).
Methods: A randomly stratiifed cluster sampling method was used to study the rural population of Yunnan province and 16-MDCT scan was performed in 212 subjects for evaluating their CAC and calculating CACS. The subjects were divided into 2 sets of groups according to the age and CACS value. Age (51-60) years group,n=108 and Age (61-71) years group,n=104; CACS<1 group,n=162, 1≤CACS<100 group,n=33 and CACS≥100 group,n=17. The PPD level and the relationship between CACS and PPD were compared among different groups.
Results: The average PPD level in Age (61-71) years group was (44.67±13.87) mmHg and in Age (61-71) years group was (50.00±17.44) mmHg,P=0.015, PPD was positively related to age, rs=0.202,P=0.003. The average PPD level in CACS≥100 group, CACS<1 group and 1≤CACS<100 group were (55.22±18.79) mmHg, (46.87±15.46) mmHg and (45.20±15.89) mmHg respectively,P<0.05. The patients with increased PPD level in CACS≥100 group was 47.1%, in CACS<1 group was 17.3% and in 1≤CACS<100 group was 15.2%,P<0.05. Spearman rank correlation analysis indicated that PPD level was positively related to CACS, rs=0.282,P=0.047, with adjusted confounding factors such as age and blood cholesterol level, the PPD was still positively related to CACS.
Conclusion: PPD as a risk factor of coronary artery disease is related to CACS in rural population of Yunnan province, the CACS increased accordingly with the elevated PPD level.

OBJECTIVE: To explore the distribution of allergen tested by skin prick test (SPT) in about 5,843 allergic rhinitis patients in south Shanghai. METHOD: SPT test was conducted in 5,843 allergic rhinitis patients who came to our clinic from January 2007 to August 2012. The result was analyzed by age, sex and year. RESULT: The top three allergens by percentage are dermatophagoides pteronyssinus, dermatophagoides culinae and fungus among 15 common allergens. Incidence rate between male and female in each year had statistical significance, both of which showed no increasing trend with year. Incidence rates among different age groups aging from 6 to 17 years' old had no statistically significant difference, but statistically significant difference among different age groups existed in other age groups. Incidence rate showed increasing trend with year in age group of 40-65, which was not observed in other groups. The incidence rate showed decreasing trend with age in male and female, while the incidence rate in male was always higher than female. CONCLUSION In south Shanghai, primary allergens causing allergic rhinitis are dermatophagoides pteronyssinus, dermatophagoides culinae and fungus. Statistically significant difference about allergic rhinitis existed in age and sex. SPT has important significance in diagnosis of allergens.

Objective: To prospectively investigate the feasibility of shear wave elastography (SWE) as a new quantitative and objective method for evaluating the stiffness of the gastrocnemius medialis (GM) muscle during passive stretching in patients with Parkinson’s disease (PD). Materials and Methods: SWE of the GM muscle was performed in 28 patients with PD [13 female and 15 male; mean age ± standard deviation (SD): 63.0 ± 8.5 years] and 12 healthy controls (5 female and 7 male; mean age ± SD: 59.3 ± 6.4 years) during passive ankle rotation. A Young’s modulus-ankle angle curve was constructed. The GM slack angle and baseline Young’s modulus (E 0) were compared between the markedly symptomatic and mildly symptomatic sides of patients with PD, and healthy controls. Additionally, the correlation between the GM slack angle and the severity of rigidity, and the observer reproducibility of SWE in determining the GM slack angle were evaluated. Results: The GM slack angle was smaller on both the markedly and mildly symptomatic sides in patients with PD than in healthy controls (mean ± SD of -29.13° ± 3.79° and -25.65° ± 3.39°, respectively, vs. -21.22° ± 3.52°; p < 0.001 and p = 0.006, respectively). Additionally, in patients with PD, the GM slack angle on the markedly symptomatic side was smaller than that on the mildly symptomatic side (p = 0.003). The E 0 value was lower on both the markedly and mildly symptomatic sides in patients with PD than in healthy controls (mean ± SD of 10.11 ± 2.85 kPa and 10.08 ± 1.88 kPa, respectively, vs. 12.23 ± 1.02 kPa; p = 0.012 and p < 0.001, respectively). However, no significant difference was found between the markedly and mildly symptomatic sides in patients with PD (p = 0.634). A negative linear relationship was observed between the GM slack angle and lower limb rigidity score on the markedly symptomatic side in patients with PD (r = -0.719; p < 0.001). The intraclass correlation coefficients for observer reproducibility of SWE ranged from 0.880 to 0.951. Conclusion The slack angle determined by SWE may be a useful quantitative and reproducible method for evaluating muscle stiffness in patients with PD.

Objective To evaluate the effect of TanshinonneⅡA preconditioning on nuclear factor kappa B ( NF-κB ) signaling pathway in N9 cells subjected to oxygen-glucose deprivation and restoration ( OGD∕R) . Methods N9 cells cultured in vitro were divided into 4 groups ( n=16 each) by using a ran-dom number table method: control group ( C group) , OGD∕R group, vehicle group ( V group) and Tanshi-none ⅡA preconditioning group ( TP group) . N9 cells were subjected to O2-glucose deprivation for 4 h fol-lowed by restoration of O2-glucose supply for 24 h to establish the OGD∕R model. Group C receive no treat-ment. In group TP, N9 cells were cultured in medium containing Tanshinone ⅡA ( final concentration 5 mg∕L) for 24 h before the model was established. Dimethyl sulfoxide was added to the culture medium in group V. At the 24 h of reoxygenation, the level of lactate dehydrogenase ( LDH) and nitric oxide ( NO) in culture medium was detected by spectrophotometry, cell apoptosis was assessed by using TUNEL, and the expression of NF-κB in nucleus was detected by Western blot. The apoptosis rate was calculated. Results Compared with group C, the levels of LDH, IL-β, TNF-α and NO in culture medium and apoptosis rate were significantly increased, and the expression of NF-κB in nucleus was up-regulated in OGD∕R, V and TP groups ( P<0. 05) . Compared with group OGD∕R, the levels of LDH, IL-β, TNF-αand NO in culture me-dium and apoptosis rate were significantly decreased, and the expression of NF-κB in nucleus was down-reg-ulated in group TP ( P<0. 05) , and no significant change was found in the parameters mentioned above in group V ( P>0. 05 ) . Conclusion The mechanism by which Tanshinonne ⅡA preconditioning reduces OGD∕R injury to N9 cells is related to inhibiting NF-κB signaling pathway.
