Objective To analyze the relation between glycosylated hemoglobin (HbA1c) and coronary heart disease (CHD) among diabetic and non-diabetic individuals.Methods A total of 1190 in patients from January 2009 to September 2009 were selected and divided into two groups:225 patients with diabete mellitus and 965 patients without.We collected the age,sex,triglyceride ( TG),total cholesterol ( CHO),high-density lipoprotein ( HDL-C),low-density lipoprotein ( LDL-C),fasting blood-glucose (FBG),glycosylated hemoglobin (HbA1c),high-sensitivity CRP (hs-CRP) and analyzed the relation between these indexes and CHD in diabetic and non-diabetic individuals respectively,then,analyzed the difference of HbA1c between patients with and without CHD after correcting the differentiating factor with a multivariable-adjusted model.Meanwhile,according the HbA1c level,we divided all participants into four groups:4.0％ -5.4％( Ⅰ),5.5％ -5.9％ ( Ⅱ),6.0％ -6.4％ ( Ⅲ),≥6.5％ ( Ⅳ),and observed the distribution of HbA1c and coronary heart disease in diabetic and non-diabetic individuals respectively.Results ( 1) In non-diabetic individuals,statistically significant difference of male( 80.5％ υs 62.7％),age [ ( 59 ±11) years υs (55 ± 11) years],FBG [(5.62 ± 1.48) mmol/L υs (5.30 ±0.84) mmol/L],HbA1c [(5.98±0.92)％ υs (5.65 ±0.53)％],CHO [(4.48 ±1.01) mmol/L υs (4.77 ±1.04) mmol/L],LDL-C [(2.59±0.87) mmol/L υs (2.79 ±0.86) mmol/L],HDL-C [(1.08 ±0.26) mmol/L υs(1.21 ±0.32) mmol/L] was observed between patients with and without CHD (P ＜0.01),however,in diabetic individuals,only LDL-C [ ( 2.56 ± 0.81) mmol/L υs ( 3.07 ± 0.90) mmol/L],CHO [ (4.44 ±0.95) mmol/L υs ( 5.08 ± 1.16) mmol/L] were observed ( P ＜ 0.0 1).(2) In all participants,the higher of HbA1c,the higher of CHD percent,compared to patients without CHD,the percent of high HbA1c in CHD patients was significantly higher.After adjusting for age,sex,HDL-C,HbA1c was an independent risk marker for CHD in non-diabetic individuals ( OR:1.935,95％ CI:1.356 - 2.762,P ＜ 0.05),however,links between FBG in the non-diabetic range and CHD appeared weaker after controlling indexes listed above( OR:1.507,95％CI:1.082 -2.098,P＜0.05).Conclusion HbA1c is an independent risk factor for CHD in nondiabetic individuals and prior to FBG.

Objective To compare the effect of Baikerui compound lysostaphin (FE complex phosphoesterasum) disinfectant and povidone iodine in treatment of burn wound infection resulted from gram-positive (G ±) coccus.Methods The study involved 60 patients with superficial second degree burns (1％-5％ TBSA； age range of 18-50 years).All the patients received bacterial culturing of wound secretions prior to treatment.Every 20 patients were indentified with infection of staphylococcus aureus (SA),staphylococcus epidermidis (SE),and enterococcus (EC) respectively and randomized into control group and experiment group,with 10 patients per group.Patients allocated to the experiment group were covered with four-layer sterile gauze soaked into the Baikerui compound lysostaphin disinfectant,while the patients in the control group were treated with four-layer sterile gauze soaked into the povidone iodine.Dressing was changed once a day.Wound culturing was performed again at each day of the 5-day treatment.Wound healing was compared among each group.Results SA wound infection turned negative for all the 10 patients in experimental group and three patients in control group (P ＜ 0.01).SE wound infection turned negative for all the 10 patients in experimental group and six patients in control group (P ＜ 0.05).EC wound infection turned negative for nine patients in experimental group and seven patients in control group (P ＞ 0.05).Mean wound healing time was (10.87 ± 1.93) days for experimental group and (13.31 ± 2.89) days for control group (P ＜ 0.05).Conclusion Baikerui compound lysostaphin disinfectant can effectively prevent burn wound infection with common G + coccus and accelerate wound healing.

Objective To study the effects of methylmercury chloride(MMC) on protein kinase C(PKC) activities in rat developing cerebellum.Methods The animals in experimental groups were fed standard rat chow with(0.75 mg) MMC(ExpⅠ),1.5 mg MMC(ExpⅡ) and 3.0 mg MMC(ExpⅢ)respectively for 90 d before gestation to(30 d) post parturition.Cerebella of pups from each group on postnatal days(PND) 3,7,17,21 and 30 were dissected. All the samples were separated into cytosol and membrane subcellular fractions and assayed for PKC activity by the improved method from Takai′s.Results Membrane and cytosolic PKC activities of pups′ cerebella from certain experimental groups were significantly higher than those of corresponding control group,PKC activities of rats from ExpⅡ,ExpⅢ and PND 3,7,14 in ExpⅠwere significantly higher than those in control group((P

Objective To analyze the correlation between the positive rate of autoantibody and hepatitis C virus load and the relationship between the positive incidence and the status of liver function in patients infected HCV.Methods 168 patients infected hepatitis C virus were included,to detect serum autoantibody,HCV loads and liver function file.And 129 healthy controls were collected to test the serum autoantibody.Using the Chi-square test to analyze the count data,and performing student test or Nonparametric test to study measurement data,compared the positive rate of autoantibody in patients with HCV and that in healthy controls.Analyzed the correlation among the positive incidence of autoantibody,HCV load and the status of liver function in patients infected HCV,and studied the relationship of the positive rate of autoantibody with age and also with gender of the patients.Results The positive rate of autoantibody in patients with HCV was 35.12%(59/168),in which ANA accounted for 33.93%,SMA took up 2.98%,AMA-M2 made up 1.80% and anti-LKM1 1.20%.No patient existed LC-1 or SLA/LP in his/her serum.The total positive rate of autoantibody and ANA both were higher in pa-tients than in healthy controls (χ2=23.179,P=0.000;χ2=21.360,P=0.000).There existed no significant difference in the levels of HCV load,total bilirubin (TBil),ALT and AST between the patients whose autoantibody examinations were positive and those who were negative in autoantibody test (χ2=0.113,P=0.945;Z=-1.087,P=0.277;Z=-1.356,P=0.175;Z=-0.153,P=0.878).The positive rate of autoantibody not correlated with the gender (χ2=2.897,P=0.089), but related to the age (t=3.274,P=0.001)of the patients.There existed significant difference in the levels of ALT,AST and the age between the patients HCV RNA negative and those HCV RNA positive (Z=-6.430,P=0.000;Z=-6.123, P=0.000;t=-3.152,P=0.002),and the patients whose HCV RNA were negative younger than those who with HCV RNA positive (44.17 vs 55.27 years).Conclusion It is easy for autoimmunity to occur on persons infected HCV.The posi-tive rate of autoantibody is related to patients’age,but not to the HCV amount in patients.Besides,it cannot predict the sta-tus of the patients’liver injury that weather the autoimmunity appears.But HCV load correlated with patients'age and liver inj ury,which older group patients bring higher virus load and had more serious liver damage.

Objective:To investigate the effect of Methylmercury chloride chronic exposure on PKCδexpression developing cer-ebellum.Methods:Establishment of cerebellum damage model of developmental rats by chronic MMC exposure .In Situ Hybridization and Western blot analysis were performed to detect the expression of PKC isozyme .Results: PKCδ was expressed at high levels at birth, but no significant change was observed with the increase in the time of birth corresponding to brain Hg 2+level, expression of PKCδ in cerebellum of experimental groups was markedly higher than that of control group .Conclusion: Neurotoxicity of Methylmercury chloride exposure might be mediated by PKCδexpression up-regulating in developmental cerebellum .

Objective To investigate the setup error for nasopharyngeal carcinoma (NPC) patients with poor compliance using kV cone-beam computed tomography,and to calculate the expansion margin from the clinical target volume (CTV) to planning target volume (PTV).Methods In 45 NPC patients from 2013 to 2015,the setup error,95％ confidence interval (CI)-1 for random error,and PTV-1 value were calculated.Moreover,in 16 NPC patients with poor compliance based on five verifications (random error not within 95％ CI-1),the setup error,95％ CI-2 for random error,and PTV-2 value were calculated.For the 16 special patients,PTV-1 and PTV-1 combined with PTV-2 were used to develop the plan-1 and plan-2,respectively.The dosimetric difference between plan-1 and plan-2 was evaluated.Results Both PTV-1 and PTV-2 had the largest expansion margin in the y direction.The CTV of plan-1 could not meet the requirement of the prescription dose after the setup error was introduced.Compared with plan-1,the V95％ and D95 values for the CTV of plan-2 were increased by 6.26％ and 4.43％,respectively.The D01 value was significantly larger in plan-2 than in plan-1 (P=0.005),which,however,met the clinical requirement.Conclusions In patients with poor compliance,the dose to target volume can be effectively elevated and the normal tissue can be spared from damage when PTV-1 combined with PTV-2 is selected as expansion margin.

Objective To assess the pituitary function in patients with pituitary adenoma after transsphenoidal ectomy of hypophysoma.Methods Data of 106 patients with pituitary adenoma who were admitted in endocrine department and underwent the operation in PLA General Hospital from January 1993 to January 2010 were collected.Assessments of pituitary function were made before and after surgery.Results Total 23.6％ and 16.0％ of 106 patients underwent pituitary function evaluation by 1 week and 3 months after surgery,respectively.23.5％ and 5.9％ of patients with hyopituitarism before surgery underwent pituitary function evaluation by 1 week and 3 months after surgery respectively,and the respective figures in those without hypopituitarism were 23.6％ and 20.8％.The incidences of new onset of hypopituitarism among 106 patients that underwent surgical procedure were 48.0％ within 1 week after surgery and 35.3％ by 3 months after surgery.Conclusion The rate of re-evaluation of pituitary function by 1 week and 3 months after pituitary surgery was low.Probably,many patients were missed the diagnosis of hypopituitarism after pituitary surgery.

Objective To assess the causes of sildenafil failure and the feasibility of successfully rechallenging non-responding patients. Methods A total of 126 consecutive erectile dysfunction (ED) patients from Jan 2009 to Dec 2009 who claimed poor response to sildenafil (sildenafil 100 mg on demand, at lease 4 epiodes) were enrolled into the study. All patients received sexual reeducation and were treated with sildenafil, taken on a daily dose of 50 mg for 4 weeks. The International Index of Erectile Function-5 (IIEF-5), Rigiscan, serum testosterone or penile Doppler were used to evaluate ED and the cause of on-demand sildenafil failure. End point efficacy of rechallenging was evaluated using the IIEF-5 and the sexual encounter profile (SEP) 'Were you able to insert your penis into your partner's vagina?' and 'Did your erection last long enough to achieve successful intercourse?'. Results The recruited patients comprised of 41 cases with psychological ED, 39 cases with hypogonadism ED, 28 cases with diabetes mellitus ED and 18 cases with vascular ED. Compared with pretreatment and on-demand sildenafil baseline, daily administration of sildenafil significantly enhanced all efficacy outcome variables. The IIEF-5 was significantly improved after daily sildenafil (12.3 ± 2.9 vs18. 8±4.4, P＜0.01), 78 patients responded to daily sildenafil. The overall salvage rate was 61.9%(78/126). Conclusions Sexual reeducation and daily administration of sildenafil may be able to salvage many patients with ED who were sildenafil non-responders.

Objective To estabalish a new conception, Erectile Dysfunction-no sexual life (ED-NS), so as create an evaluating questionnaire, Self-estimation Index of erectile function-No sexual life (SIEF-NS) so as to investigate its clinical reliability. Methods The conception of ED-NS was identified and the SIEF-NS questionnaire was established. Patients who complained of ED-NS and normal controls were enrolled into the research and assessed the erectile function was assessed with SIEF-NS.The SIEF-NS includes 12 questions, such as sexual libido, general erectile function, nocturnal penile erection, erectile function during foreplay, erectile function during audio-video sexual stimulation,confidence, depression, etc and each question has 5 point scales. Results Sixty-one ED-NS patients and 57 controls were enrolled into the study and assessed erectile function with SIEF-NS. The mean score of each question and integral score of SIEF-NS in ED-NS patients were significantly different from normal controls (P＜0. 05). When the integral score was 35 points according to the ROC curve of integral score, the sensitivity of SIEF-NS was 88.5% and specificity was 96. 5%. Conclusions ED-NS is a new conception to define patients who have erectile dysfunction without sexual life. SIEFNS is suggested to be a useful method for the evaluation of ED-NS patients.

ObjectiveTo assess the cause of tadalafil failure and the feasibility of successfully rechallenging nonresponding patients.Methods A total of 80 consecutive erectile dysfunction ( ED ) patients who claimed poor response to tadalafil were enrolled into the study.A self-administered tadalafil-use questionnaire composed of eight questions was applied to assess how they had used tadalafil.Subjects were given thorough instruction based on individual answers and four doses of tadalafil 20mg.After a 2-week follow-up,end point efficacy of rechallenge was evaluated using the sexual encounter profile (SEP),which was recommended by international advisory panel in 2004.ResultsA total of 45 subjects had one or more areas of major suboptimal use of tadalafil:21.2％ did not know that sexual stimulation was necessary for tadalafil to work,87.5％ attempted to use tadalafil less than four times,57.5％ took a maximal dose less than 20 mg,and 84％ felt nervous or anxious.Of the 65 patients undergoing tadalafil rechallenge,30 patients answered “yes” to SEP2 and SEP3.The response rate to rechallenge was 46.2％ ( 30/65 ).ConclusionsInappropriate use of tadalafil was major cause of tadalafil non-pesponse.The efficacy of tadalafil could be improved to a better extent by education of patients.
