BACKGROUND:The micro-ecological environment has been broken when the ocular prosthesis was inset into the conjunctival sac. The recede of self cleaning function is more conducive to the microbial growth and colonization. The cleaning of plaque biofilm on ocular prosthesis surface affects the patient's wearing comfort and quality of life. It is necessary to seek an effective cleaning method. OBJECTIVE:To compare the clearance effect of five cleaning methods on the palque biofilm on ocular prosthesis surface. METHODS: The conjunctival secretions from 84 patients who were subjected to ocular prosthesis repair were taken for bacterial culture and identification. Fifty pieces of self-curing resin and thermosetting resin artificial eyes were produced. The artificial eyes in each group were randomly divided into five groups, and were cleaned respectively with clear water, volume fraction of 75% ethanol, Boston SIMPLUS, polident and toothpaste. After the completion of the cleaning, the test piece was conducted residual biofilm culture. The clearance effects of different processing modes were evaluated using colony counting method. RESULTS AND CONCLUSION: Eighty-four specimens were submitted for inspection, of which 49 were positive. The Staphylococcusaureus separation rate was 14.29%.Staphylococcus epidermidis separation rate accounted for 13.10%. Maxwel Corynebacterium separation rate accounted for 7.14%. When water, Boston SIMPLUS and toothpaste were used for cleaning, theStaphylococcus aureus colony number in the self-curing resin group was higher than that in the thermosetting resin group (P< 0.05); when ethanol and polident were used for cleaning, there was no difference in the Staphylococcus aureus colony number between these two groups. In self-curing resin, the colony count in the clear water treatment group was higher than that in the other treatment groups (P < 0.05). The colony count in the ethanol treatment group was lower than that in the Boston SIMPLUS group (P < 0.05). There was no significant difference in the colony count between other groups. In thermosetting resin, the colony count in the clear water treatment group was higher than that in the other treatment groups (P < 0.05). There was no significant difference in the colony count between other groups. These results demonstrate that ethanol, Boston SIMPLUS, polident and toothpaste have better cleaning effects onStaphylococcus aureusbiofilms on the surface of two kinds of ocular prostheses than the clear water rinse. Overal, it is encouraged to clean the artificial eyes using polident and Boston SIMPLUS, in order to avoid the occurrence of microbial infection in the conjunctival sac after wearing ocular prosthesis.

ObjectiveTo establish the reference intervals of serum triiodothyronine (TT3),the thyroxine ( TT4 ),free triiodothyronine ( FT3 ),free thyroxine ( FT4 ) and thyroid-stimulating hormone (TSH)in the apparently healthy individuals of Beijing and Shanghai.Methods According to the requirement for laboratory support for the diagnosis and monitoring of thyroid diseases in the National Academy ofClinicalBiochemistry(NACB)laboratorymedicinepracticeguidelines, therewere 390 apparently healthy individuals tested (221 male,169 female,18 -65 years old) from Beijing and Shanghai for serum TT3,TT4,FT3,FT4 and TSH on American Beckman UniCel DXI 800 Automatic Chemiluminescent Analyzer.All markers were analyzed between gender,region,age group using t test and ANOVA.The reference intervals of all markers were determined by P2.5 - P97.5.ResultsTT3,TT4,FT3,FT4,TSH levels in the male group were ( 1.90 ± 0.32) nmol/L,( 116.77 ± 18.02) nmol/L,( 5.28 ±0.67) pmol/L,( 11.54 ± 1.97) pmol/L,( 1.92 ± 1.12 ) mIU/L,respectively,while the above indicators in the female group were ( 1.82 ± 0.32) nmol/L,( 115.73 ± 14.39 ) nmol/L,(5.04 ± 0.59 ) pmol/L,( 10.94 ± 1.45) pmol/L,( 2.37 ± 1.86 ) mIU/L,respectively.When comparing the results in genders,statistical significance was shown in TF3,FT3,FT4 and TSH of two gender groups( t =2.377,3.642,3.471,2.520,all P ＜ 0.05 ).When comparing different regions,statistical significance was only shown in FT3 ( t =6.410,P ＜ 0.05 ),in which Beijing group was (5.01 ± 0.63) pmol/L,and Shanghai group was (5.41 ±0.61 ) pmol/L,and no significant difference were shown in other four markers.Correlation analysis showed that TT4 was positively correlated with age (r =0.22,P ＜ 0.001 ) while TSH was negatively correlated with age ( r =- 0.12,P ＜ 0.05 ).TT3,TT4,FT3,FT4,TSH reference intervals were ( 1.22 - 2.50 ) nmol/L,(83.37 - 149.37 ) nmol/L,( 3.88 - 6.48 ) pmol/L,( 7.70 - 14.86) pmol/L,( 0.38 - 5.58 ) mIU/L,respectively.ConclusionDifferences of serum thyroid hormones were observed in different areas of China,It is important to establish reference intervals of the serum thyroid hormones in Chinese population.

ObjectiveTo observe the effect of sport walking on heart and lungs functions in old women.MethodsForty-two old women aged from 60 to 69 had sport walking for 4 months; the speed and intensity were controlled according to their heart rate respectively. The indexes of respiration, circulation and rheoencephalography were measured before and after exercise.ResultsAfter exercise, blood-pumping function of heart improved obviously, stroke volume increased from (65.22±11.41)ml to (72.10± 10.78)ml, ejection fraction increased from (60.10±5.03)% to (68.78±6.25)%, while heart rate declined from (77.45±8.69) times/min to (7.89±8.21)times/min, capacity increased from (2.86±0.36)L to (3.34±0.53)L, and maximal voluntary ventilation for every minute increased from (96.14± 15.21)L to (114.02±16.01)L, significantly different compared with that before treatment ( P<0.01). The fluid time of rheoencephalography reduced from (0.171±0.058)s to (0.128±0.049)s ( P<0.01).ConclusionSport walking under proper intensity can improve the function of respiration and circulation system in old women, so it is a good way to keep health for the elders.

OBJECTIVETo clarify the various diagnostic connotations of pseudomyxoma peritonei (PMP) and to study their prognostic implications.

METHODSClinicopathologic features and follow-up data of 40 patients with PMP diagnosed in The General Hospital of PLA were retrospectively reviewed. The cases were histologically classified into 3 subcategories: disseminated peritoneal adenomucinosis (DPAM), peritoneal mucinous carcinomatosis (PMCA), and PMCA with intermediate or discordant features (PMCA-I/D). The survival rate was calculated using Kaplan-Meier method and the difference was statistically analyzed.

RESULTSTwelve of the 40 patients died on follow up. The duration of survival ranged from 2 to 348 months (medium = 37.5 months). In general, the 3-year, 5-year and 10-year survival rates were 79.0%, 69.4% and 53.0%, respectively. The mean age of the patients at the time of diagnosis was 50.3 years (age range = 22 to 76 years). The male-to-female ratio was 1:1. The age and sex of patients, frequency of operation and presence of ovarian involvement did not correlate with duration of survival. On the other hand, the presence of appendiceal tumor, parenchymal invasion of abdominal viscera, cellularity, architecture, nuclear atypia and mitotic activity of the peritoneal lesion significantly correlated with survival. There was also significant difference in survival between DPAM, PMCA-I/D and PMCA subcategories (P = 0.018). The difference in survival rate between PMCA-I/D and PMCA subgroups however was not statistically significant (P = 0.096). The outcome of DPAM was significantly better when compared with the combined group of PMCA-I/D and PMCA (P = 0.006).

CONCLUSIONSIn general, the 10-year survival rate of PMP was low, despite the relatively benign-looking or low-grade pathologic appearance. Peritoneal lesions with higher cellularity, conspicuous nuclear atypia and higher mitotic activity are associated with a lower survival rate. The prognosis was even worse in the presence of appendiceal carcinoma or parenchymal invasion of abdominal viscera. It is thus advisable to subclassify PMP into DPAM, PMCA and PMCA-I/D, due to the difference in prognostic implication.

Objective To study the distribution of antinuclear antibodies ( ANAs) in a healthy population and the significance of using ANAs screening test in medical examination .Methods The ANAs were measured by indirect immunofluorescence assay ( IIF) .The Western blot assay was used to detect fif-teen specific antibodies against auto-antigens .Results 3519 out of all 25 110 subjects showed ANAs titers>1∶100 , and among them male and female subjects were respectively accounted for 1143 and 2376 .1489 out of all subjects had ANAs titers >1∶320 , and among them male and female subjects were respectively accounted for 406 and 1083 .The positive rates of ANAs at different titers showed significant differences be -tween male and female subjects .Among subjects with ANAs titers >1∶320 , the number of male subjects showed a steady increase with the age , while the percentage of female subjects reached to two peaks during the periods of puberty and menopause .The fifteen specific antibodies were detected in 659 out of 1489 sub-jects with ANAs titers>1∶320 and anti-Ro-52 (14.2%) accounted for the majority , followed by anti-M2 (12.7%) and anti-SSA (9.6%).Conclusion ANAs can be detected among healthy population of all ages, but their distribution varied with gender and age .ANAs screening test is necessary for medical exami-nation of healthy population , especially for female during period of puberty or menopause .The population with positive ANAs should be followed-up closely and educated for the prevention of autoimmune diseases .

Objective To research the effect and safety of Reteplase for Injection combined with reduced glutathione in the treatment of acute ST segment elevation myocardial infarction.Methods Patients with acute ST segment elevation myocardial infarction (90 cases) in Jianli People's Hospital from February 2015 to February 2016 were selected and divided equally into A,B and C groups according to different treatment methods.Totally 30 patients in group A were given conventional therapy,30 patients in group B were given reduced glutathione for treatment on the basis of conventional treatment,and the other 30 in group C were given combined therapy of reteplase and reduced glutathione on the basis of conventional treatment.The vascular recanalization rate,improvement of effective indicators including creatine kinase isoenzyme (CKMB),troponin Ⅰ (cTnⅠ),left ventricular end diastolic diameter (LVEDd) and left ventricular ejection fraction (LVEF),oxidative stress kinase including superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px),and incidence of adverse events of patients were compared among the three groups.Results After thrombolysis,the vascular recanalization rate of group C at different time points (2 h,6 h and 12 h) showed significant difference compared with those of groups A and B (P ＜ 0.05).After the treatment,the effective indicators of the three groups were both significantly improved (P ＜ 0.05),and group C improved more significantly than groups A and B (P ＜ 0.05).After the treatment,the SOD and GSH-Px of groups B and C both significantly improved than group A (P ＜ 0.05),but there was no significant difference between groups B and C.After treatment,the incidence of adverse events of group C was significantly lower than those of groups A and B (P ＜ 0.05).Conclusion Reteplase for Injection combined with reduced glutathione has significant curative effect in the treatment of acute ST segment elevation myocardial infarction,which can effectively improve the cardiac function and inhibition of oxidative stress.It is of higher security but with lower incidence of adverse events.

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.
