OBJECTIVE To appraise the bacteriostatic and blocking effect and cost construction of different kinds of materials.METHODS To divide all items into three parts at random:cotton fabric,paper-plastic package,and medical grade wrinkle paper and to study the bacteriostatic and blocking effect and cost construction of them.RESULTS Paper-plastic package and medical grade wrinkle paper had better bacteriostatic and blocking properties than cotton fabric.Comparing with cotton fabric,paper-plastic package and medical grade wrinkle paper could reduce the cost separately by 27% and 50%;the cost of wrinkle paper was lower than paper-plastic package by 32%.CONCLUSIONS Paper-plastic package and wrinkle paper have better effect on blocking bacteria and less cost than cotton fabric,which deserve more extensive application in clinic.

Objectives To isolate the cardiogenic fraction, which can enhance cardiogenic differentiation of bone marrow-derived mesenchymal stem cells(MSC)from Geum iaponicum.The therapeutic effeet of the isolated cardiogenic fraction was further tested in a rat myocardial infaretion (MI)model.Method Bioassay guided fractionation method was used for the isolation of the cardiogenic fraction,named as heart repair fraction(HRF).MI was induced by a permanent ligation of left anterior descending coronary artery.The rats exhibiting similarly decreased values of left ventricle ejection fraction(LVEF) and fraction shortening(LVFS)were used.The rats in test group(n=10)were subject to HRF treatment(20 mg·kg-1·d-1)through gastric gavage daily for 4 weeks.Water alone(2 ml/d) was given through gastric gavage to rats in the control group(n=10).The cardiac function was assessed by echocardiography at different time points.Masson trichrome staining was used for evaluation of the infarct size.Morphological and immunohistochemical studies were performed to investigate the HRF mediated myocardial regeneration.Results LVEF(66.2%±6.9%)and LVFS(46.8%±5.8%)were significantly increased two weeks post HRF treatment compared with the values(LVEF:55.7%±6.0%and LVES:36.4%±5.2%)in control rats(a11 P<0.01).The improved heart function was further restored 4 weeks post HRF treatment(P<0.01).Furthermore,the treatment of acute MI with this HRF significantly reduced the infarct size(19.0%±6.1%)compared with that(31.1%±8.6%)in control rats(P<0.01).Substantial regeneration of cardiomyoeytes in infarcted region of the HRF treated heart was also observed that replaced a considerable part of the infarcted heart tissues resulting in remarkable reduction of the infarct size.Conclusion The properties of this HRF isolated from Geum japonicum in stimulating substantial regeneration of myocardium in infarct region with consequently improved cardiac function appear to be new and represent a new approach for the treatment of MI.

Objective To evaluate the efficacy and safety of Chushizhiyang ointment for the treatment of mild atopic dermatitis in infants.Methods A multicenter,randomized,open,active-controlled clinical trial was conducted.A total of 204 infants with atopic dermatitis were enrolled and randomly divided into 2 groups to be topically treated with Chushizhiyang ointment (test group,n =103) and hydrocortisone butyrate cream (control group,n =101),respectively,for 2 weeks.The improvement of eczema area and severity index (EASI) scores and quality of life was evaluated at 7 days and 14 days after the treatment,so was the incidence of adverse events and adverse reactions.Results Ninety-eight infants in the test group and 101 in the control group were included in the full analysis set,which revealed that the disease severity significantly decreased after the treatment in both groups.The EASI scores at the baseline and on days 7 and 14 were 2.47 ± 4.04,0.92 ± 1.25 and 0.39 ± 1.04 respectively in the test group,as well as 2.13 ± 2.01,0.85 ± 1.58 and 0.45 ± 1.65 respectively in the control group.Furthermore,the test group and control group both showed that EASI scores on days 7 and 14 significantly decreased compared with those at the baseline (the test group:T =-1 666,-1 793,respectively,both P ＜ 0.001;the control group:T =-1 951,-1 941,respectively,both P ＜ 0.001).No significant differences in EASI scores at the baseline or on days 7 and 14 were observed between the test group and control group (all P ＞ 0.05).The response rates in the test group and control group were 47.96％ (47/98) and 55.44％ (56/101) respectively on day 7,as well as 79.59％ (78/98) and 84.16％ (85/101) respectively on day 14,and there were also no significant differences between the two groups (both P ＞ 0.05).The adverse reactions mainly manifested as erythema,itching and scaling in the test group,as well as hypopigmentation,telangiectasia,scaling and hyperpigmentation in the control group.No significant difference in the incidence of adverse events was found between the test group (2.9％,3/103) and control group (6.9％,7/101).Conclusion Chushizhiyang ointment shows definite efficacy for mild atopic dermatitis in infants with good safety and tolerability,and can be a teatment option for mild atopic dermatitis in infants.

Objective To investigate the risk factors in association with congenital syphilis, in order to provide a basis for further improvement of the ongoing Prevention of Mother to Child Syphilis Transmis- sion Project in Shenzhen. Methods A nested case-control study was designed in neonates with risk of con- genital syphilis. The case group included 51 neonates with congenital syphilis, and the control group included 320 neonates without the disease. Results The risk factors in association with congenital syphilis were mother's age, residence, education level, weeks of gestation at time of starting standardized treatment,moth- er's TRUST titer at time of diagnosis; and also father's education level, occupation and history of multiple sex partners, as showed with univariate logistic regression analysis. After adjusted with multivariate uncondi- tional logistic regression analysis, 4 independent risk factors were found, namely, mother's age, father's edu- cation level, weeks of gestation at time of starting standardized treatment, and mother's TRUST titer at time of diagnosis. Conclusions Risk factors in association with congenital syphilis are identified, which provide important clues for effective prevention of congenital syphilis.

Objective To investigate the feasibility and efficacy of laparoscopic orchiopexy for inguinal palpable undescended testes. Methods Ninety patients with 103 inguinal undescended pal-pable testes were treated by laparoscopic orchiopexy performed by the same surgeon. There were 24 (26.7 %) left and 53 (58. 9%) right palpable cryptorchidism cases, plus 13 cases (14.4 % ) with bilat-eral undescended testes. The mean age of the patients was 17 months (range 8 months-6 years). The surgical procedures were described as following. First, the peritoneum was opened at the anterior sur-face of the spermatic vessels and vas deferens before the testis was pulled into the abdominal cavity so that the spermatic vessels and vas deferens were released and easily manipulated. Second, the inter-space between internal spermatic fascia (transversalic fascia) and processus vaginalis was divided so, that the testis could be pulled into the abdominal cavity. Finally, the trocar which was inserted from scrotum was placed through the outer ring. Finally, the testis was placed at position and fixed. Re-suits The mean operative time was 32.7±5.2 min. The processus vaginalis unclose was found in 93 (90.3%) cases; and contralateral process us vaginalis unclose were found in 12 (15.6%) cases of 77 unilateral undescended testes. The complication rate was 3(3.3%)cases, all in bilateral cases. All 103 testes were descended by laparoscopy. On follow-up ranging 6-12 months, all testes maintained good size and a proper position. Conclusions The laparoscopic approach may be a safe way to descend the inguinal palpable testes. Orchiopexy of palpable undescended testes can be done with advantages in the laparoscopic approach.

Objective To observe changes in the working memory and brain functional imaging on functional magnetic resonance imaging(fMRI) after 36 hours sleep deprivation (SD) in healthy volunteers and to explore the possible mechanism of the changes.Methods FMRI scannings were performed in ten male healthy young volunteers before and after 36 hours SD and results were analyzed using SPM2 software.Subjects were also tested LTR and PLUS task to measure the persistence and operation of working memory before and after 36 hours SD.Results The reaction time of LTR task after 36 hours SD ( (866 ± 102) ms)was significantly longer than that before SD ( (754 ± 91 ) ms, t = 2.59, P < 0.01 ).The reaction time of PLUS task after SD ( (848 ± 94) ms) was significantly longer ( t = 2.37, P < 0.05 ) than that before SD ( (756 ± 79) ms).The error rate of LTR task after SD (95.3% ± 3.56% ) was significantly higher (t=3.52,P < 0.01 ) than that before SD (84.8% ± 8.71% ).The error rate of PLUS task after SD (95.7% ±4.72% ) was significantly higher (t =3.38 ,P <0.01 ) than that before SD (84.2% ±9.66% ).There were no significant differences between the two tasks.The frontal and parietal lobes, anterior cingulate gyrus and thalamus were activated during memory tasks testing before SD.Brain activation was broader and stronger in PLUS task than in LTR task.After SD, activation in parietal lobe was decreased and activation in prefrontal and thalamus was increased significantly.Conclusions The working memory performance decreased after SD.Both LTR and PLUS tasks of working memory activate frontal and parietal lobes, anterior cingulate gyrus and thalamus.The activation of parietal lobe decreased and the activation of prefrontal lobe and thalamus increased after 36 hours SD.This is the possible mechanism of SD to causes the cognition decline.

Objective To evaluate the efficacy of eszopiclone for patients with acute insomnia and the impact of premedication with eszopiclone on sleep structure of patients with acute insomnia.Methods In an open-label,self-control trial was conducted at Changzheng Hospital Sleep Centers,and patients (n =32) with acute insomnia (12 men,20 women; mean age,36.2 years) were administered eszopiclone 3 mg for three consecutive nights.Sleep was monitored via polysomnography.The insomnia severity index (ISI),and mini-mental state examination (MMSE) were used to assess the degree of insomnia and impact of drugs on cognitive function during the day.Results Eszopiclone can shorten sleep latency ( before treatment:(52.92 ± 11.71 ) min,after treatment:(28.2 ± 10.11 ) min; t =-4.376,P ＜0.01 ),prolong total sleep time(before treatment:(365.22 ±30.13) min,after treatment:(429.18 ±26.93 ) min; t =4.102,P ＜ 0.01 ),decrease wake up times( before treatment:( 5.00 ± 1.92 ) times,after treatment:( 2.73 ± 0.91 )times; t =- 4.592,P ＜ 0.01 ),improve sleep efficiency ( before treatment:72.69％ ± 6.32％,after treatment:82.67％ ± 4.16％ ; t =3.371,P ＜ 0.01 ),reduce awake time ( before treatment:( 88.51 ±17.48) min,after treatment:(65.93 ±21.l0)min; t =-4.592,P ＜0.01 ),decrease light sleep ( NREM1 period) the percentage of time ( before treatment:12.54％ ± 2.10％,after treatment:7.30％ ± 2.90％ ;t=-3.155,P ＜ 0.01 ),and increase the percentage of slow wave sleep (before treatment:8.03％ ±5.37％,after treatment:9.31％ ±5.29％; t =4.228,P ＜0.01).No effect was observed on the percentage of NERM2 period (t =0.731,P ＞0.05) and REM period (t =-0.813,P ＞0.05).Eszopiclone can improve the quality of subjective assessment of sleep ( ISI score decreased,t =- 2.551,P ＜ 0.05) and has no significant effect on cognitive function on first the morning after patients taking the medication.Conclusion Eszopiclone can positively regulate the sleep structure in patients with acute insomnia and improve subjective assessment of sleep quality.It is safe and has no significant effect on cognitive function.
