Objective To study the distribution and antimicrobial susceptibilities of anaerobic bacteria from periodontal pockets of patients with chronic periodontitis, so as to guide the anti-infection therapy. Methods Eighty-four patients with chronic periodontitis were enrolled in this study. The anaerobes were isolated from periodontal pockets of patients with chronic periodontitis. Antimicrobial susceptibility of the anaerobes to seven kinds of antibiotics (like metronidazole, penicillin, cefmetazole, etc.) was tested with the agar dilution technique. Results A total of 305 cultivable anaerobes were isolated from periodontal pockets of 84 patients with chronic periodontitis. All patients were infected by anaerobes. 59.34%of cultivable anaerobes were gram-positive anaerobes, and 40.66%were gram-negative anaerobes. The P.melanin ogenica and P.gingivalis were the most common among the cultivable anaerobes, accounting for 51.19% and 55.95%, followed by P.intermedia (36.90%), P.micros (35.71%), F.mucleatum (33.33%), Capnocytophaga ssp (27.38%), Actinomyces ssp (10.71%), and so on. Most isolated anaerobes were sensitive to seven antibiotics. All isolated anaerobes were susceptible to Chloromycetin and Imipenem. 98.03%of isolated anaerobes were susceptible to Amoxicillin. Approximately 76%to 88%of isolated anaerobes were susceptible to Cefmetazole and Metronidazole. Susceptibility to Clindamycinum and Penicillin were 65.91%and 55.73%. Conclusions There is a close relationship between chronic periodontitis and anaerobes. P.melanin ogenica and P.gingivalis are the most frequently isolated anaerobes from periodontal pockets of patients with chronic periodontitis. Chloromycetin and Imipenem can be used for the treatment of anaerobes infected chronic periodontitis.

Objective:To examine the utilization and cost of outpatient care and their influencing fac-tors among middle and aged peasant-workers in China. Methods:The data of China Health and Retire-ment Longitudinal Study ( CHARLS) collected in 2011-2012 were used and the data on peasant-workers aged 45 years and older were analyzed with Two-part Model. Results: The four-week outpatient rate of middle and aged peasant-workers was 13. 7% (407/2 974). The determinants of the rate included gen-der, marital status, economic level, household size, the place of insurance enrollment, self-assessed health and having or having no chronic diseases. The average outpatient cost was (400. 3 ± 56. 7) yuan (RMB) and the median was 138. 0 yuan. Multivariate analyses showed that outpatient costs were higher for those males who lived in Eastern China and worked at the same place with insurance enrollment, with fair to bad self-assessed health and chronic diseases. Conclusion:Allowing higher flexibility for migrants to transfer the new rural cooperative medical system ( NCMS ) between rural and urban areas and thus making reimbursement for medical services provided by undesignated providers received immediately could increase the use of outpatient services.

The AC impedance of human hepatoma SMMC-7721 cells were measured in our laboratory by Agilent 4294A impedance analyzer in the frequency range of 0.01-100 MHz. And then the effect of hematocrit on electrical impedance characteristics of hepatoma cells was observed by electrical impedance spectroscopy, Bode diagram, Nyquist diagram and Nichols diagram. The results showed that firstly, there is a frequency dependence, i.e., the increment of real part and the imaginary part of complex electrical impedance (δZ', δZ"), the increment of the amplitude modulus of complex electrical impedance (δ[Z *]) and phase angle (δθ) were all changed with the increasing frequency. Secondly, it showed cell volume fraction (CVF) dependence, i. e. , the increment of low-frequency limit (δZ'0, δ[Z*] 0), peak (δZ"(p), δθ(p)), area and radius (Nyquist diagram, Nichols diagram) were all increased along with the electric field frequency. Thirdly, there was the presence of two characteristic frequencies: the first characteristic frequency (f(c1)) and the second characteristic frequency (f(c2)), which were originated respectively in the polarization effects of two interfaces that the cell membrane and extracellular fluid, cell membrane and cytoplasm. A conclusion can be drawn that the electrical impedance spectroscopy is able to be used to observe the electrical characteristics of human hepatoma cells, and therefore this method can be used to investigate the electrophysiological mechanisms of liver cancer cells, and provide research tools and observation parameters, and it also has important theoretical value and potential applications for screening anticancer drugs.

OBJECTIVE:To investigate therapeutic efficacy and safety of Acetic acid goserelin sustained-release implants (AGRI) in the treatment of ovary endometrium cyst (OEC) recurrence after laparoscopic enuleation of ovarian cyst. METHODS:Totally of 60 patients with OEC recurrence after laparoscopic enuleation of ovarian cyst in Zhangjiagang First People's Hospital dur-ing Jan. 2013-Jan. 2015 were divided into control group and observation group according to random number table,with 30 cases in each group. Both groups were given Mifepristone tablets orally 25 mg,qd. Control group was given Gestrinone capsules orally 2.5 mg,twice a week. Observation group was given AGRI subcutaneously 3.6 mg,once a month. Both groups were treated for consec-utive 6 months. Clinical efficacies of 2 groups were observed as well as the levels of serum follicle stimulating hormone(FSH),lu-teinizing hormone(LH)and estradiol(E2),VAS scores of dysmenorrheal and chronic pelvic pain before treatment,3,6 months af-ter treatment. The occurrence of ADR and the prognosis of 12-month follow-up were observed in 2 groups. RESULTS:Total re-sponse rate of observation group was 86.67%,which was significantly higher than 70.00%of control group,with statistical signifi-cance(P<0.05). After 3 months of treatment,the levels of FSH and LH in 2 groups were decreased significantly compared to be-fore treatment,with statistical significance (P<0.05);the level of E2 had no change;there was no statistical significance in the levels of FSH and LH between 2 groups(P>0.05);after 6 months of treatment,the levels of FSH,LH and E2 in 2 groups were decreased significantly,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). After 3 and 6 months of treatment,VAS score of dysmenorrheal and chronic pelvic pain in 2 groups were decreased signifi-cantly,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). The inci-dence of ADR in observation group was 40.00%,which was significantly higher than 16.70% of control group,with statistical sig-nificance(P<0.05). There was no statistical significance in recurrence rate between 2 groups(P>0.05). The recovery rate of men-struation in observation group was 86.67%,the rate of dominant follicle formation was 60.00% and pregnancy rate was 53.33%, which were significantly higher than 46.67%,46.67% and 33.33% of control group,with statistical significance(P<0.05). CON-CLUSIONS:AGRI shows significant therapeutic efficacy for OEC recurrence after laparoscopic enuleation of ovarian cyst,can ef-fectively relieve dysmenorrhea and chronic pelvic pain,increase the rate of pregnancy. There is still recurrent cases after drug with-drawal. The incidence of ADR is high,but the symptoms are mild.

Objective:To determine the valproate concentration in plasma of epilepsy patients by HPLC, and compare with the re-sults of chemiluminescence microparticle immunoassay ( CMIA) to evaluate the consistency of the two methods. Methods:HPLC and CMIA was respectively applied to determine the plasma concentration of valproate in 230 epileptic patients. The correlation of the two methods was studied by Passing-Bablok regression and Bland-Altman method. Results:The regression equation of the determination re-sults of HPLC (Y) and CMIA (X) was Y=1. 069 7X+2. 338 2 (R2 =0. 969, n=230), which showed promising correlation. Bland-Altman analysis showed that the consistency of the two methods was poor, and the values of HPLC were higher. Conclusion: HPLC and CMIA used for the determination of valproate plasma concentration show good correlation. However, the consistency is poor and there is system error. In the clinical treatment, adjustment and choice should be paid more attention.
