The production conditions of glutathione with shaking flask fermentation by the mutant Saccharomyces J-X25, a methionine-defected strain were studied, and the optimum culture conditions are as follows: initial pH6. 0, temperature 30℃, 100ml in 500ml flask, the inoculum size 10% and agitation rate 220r/min. The emphasis was on the stimulating effect on the cells by dioxogen and the sodium lactate as surfactant. Both of which were added at the logarithmic phase of fermentation, and the GSH production was up to 0. 253g/L , 52% higher than the control without the additions. Compared with the production of GSH initial strain that by the mutant in optimum conditions was increased by 79%.

Objective:To share the experience of clinical cooperation of physicians and clinical pharmacists in the treatment of one case of rodenticide poisoning. Methods: One case of rodenticide poisoning was early diagnosed by physicians according to the con-sciousness disorder and coagulation dysfunction. Clinical pharmacists participated in the drug treatment actively through providing vita-min K1 at the dose of 30 mg·d-1 as the treatment dose and monitoring the effectiveness. Toxicology analysis was recommended, and 718 ng·ml-1 bromadiolone was found out in the blood samples. According to the long half-life of bromadiolone, the initial duration of treatment was set at 2-3 months, while follow-up plan and final duration of treatment were defined based on coagulation parameters and poison concentration monitoring results. Results:The patient recovered rapidly after hospitalization due to the cooperation of physicians and clinical pharmacists through quickly correcting diagnosis of physicians and actively participating in medication of clinical pharma-cists. After the 3-month treatment, the coagulation parameters of the patient were normal and the patient was discharged with follow-up. Conclusion:The collaboration of physicians and clinical pharmacists leads to the optimal regimen with early, full dose and long course of vitamin K1 therapy.

Objective To investigate the association factors affecting the course of IVF/ICSI-ET. Methods The clinical data of 348 cycles of IVF/ICSI-ET in patients with different causes of infertility were analyzed retrospectively. Results Ovarian reserve and response to stimulation declined with aging. The ability of bFSH predicting ovarian response was low. E 2 peak concentration, number of big follicle and retrieved oocytes decreased significantly when bFSH concentration evelated. The number of big follicle and retrieved oocytes obviously increased with the E 2 peak concentration increasing. The number of antral follicle and volume of ovary were positive relation with ovarian response. None of the factors above could predict the outcome of IVF indenpedently. Conclusion Age was strongly associated with ovarian reserve and response. The bFSH level was one of the indices reflecting ovarian reserve, and had the limited capability for predicting ovarian response and IVF outcome.E 2 peak concentration could not predict the IVF consequence. The number of total antral follicle and volume of ovary were the most direct index reflecting ovarian response. The conditions of patients should comprehensively be evaluated to raise the pregnant rate of IVF.

Objective To investigate the clinical significance of anti-nuclear envelope protein antibody (gp210),anti-soluble acid resistant nucleoprotein (sp100) and anti-mitochondrial antibody M2 subtype (AMA-M2) in sjogren syndrome (SS) and primary biliary cirrhosis (PBC).Methods A total of 241 hospitalized patients diagnosed with connective tissue disease (CTD) were recruited.Anti-gp210,anti-sp100 and AMA-M2 were detected by indirect immunofluorescence.Results (1) Positive rate of AMA-M2,anti-sp100 and antigp210 in 241 cases CTD patient were 10.4％ (25/241),3.3％ (8/241) and 2.9％ (7/241) respectively.(2) There were 16 cases with SS,5 cases with SS-PBC overlap syndrome and 17 cases with PBC in 241 patients with CTD.Distinction among groups of PBC,SS,SS overlapping PBC of positive incidence of AMA-M2 antibody (x2 =6.584,P =0.03) and anti-gp210 (x2 =8.735,P ＜ 0.01) were significantly different,while there was no apparent difference about positive rate of anti-sp100 among the three groups (x2 =3.343,P =0.18).(3) Positive expression of either antibody of anti-gp210 or anti-sp100 in the three groups of SS,SS overlapping PBC,PBC were 3 cases,4 cases,4 cases respectively.The positive rates of any of three autoantibodies in three groups of were 8 cases,5 cases,13 cases respectively.(4) There were significant difference in terms of serum ALB(t =3.858,P＜0.000 1),TSB(t =5.473,P＜0.000 1),ALT(t =2.235,P=0.026),AKP(t =3.141,P =0.002) and γ-GT (t =2.317,P =0.021) in liver damaged patients of all CTD between AMA-M2 positive and negative patients (P ＜ 0.05).However,serum TSB in anti-sp100 positive and negative patients were differed (t =7.892,P ＜ 0.000 1).Serum AKP was different between anti-gp210 positive and negative patients (t =2.451,P =0.015).Conclusion Positive rate of anti-gp210,anti-sp100 and AMA-M2 are the highest in patients with SS overlap of the PBC among CTD patients.Combined detection can improve the sensitivity of diagnosis.Antisp100 and anti-gp210 are valuable for the diagnosis of SS-PBC overlaps syndrome with negative AMA-M2.

Objective: To analyze the epidemic trend of viral hepatitis in Nanjing from 1989 to 2019 and predict the incidence in 2020, so as to provide reference for the prevention and control of viral hepatitis. Methods: The incidence data of viral hepatitis in Nanjing from 1989 to 2019 was retrieved from Nanjng Center for Disease Control and Prevention and National Infectious Disease Reporting System. The epidemic trend was analyzed by estimating the annual percent change ( APC ) and the average annual percent change ( AAPC ). The seasonal incidence of different types of viral hepatitis was analyzed by seasonal index. The autoregressive integrated moving average model ( ARIMA ) was built to predict monthly incidence rate of viral hepatitis in 2020. Results: The annual incidence rate of viral hepatitis was 62.00/100 000 in Nanjing from 1989 to 2019, showing a downward trend ( AAPC=8.4%, P<0.05 ). From 1998 to 2019, the annual incidence rates of hepatitis A, B, C and E were 1.98/100 000, 14.31/100 000, 2.30/100 000 and 2.60/100 000. The incidence of hepatitis A and B showed downward trends ( AAPC=-11.81%, -6.02%, both P<0.05 ); the incidence trend of hepatitis C was not obvious ( P>0.05 ); the incidence of hepatitis E showed an increasing trend ( AAPC=4.82%, P<0.05 ). From 2015 to 2019, the third and fourth quarters were the epidemic seasons of hepatitis A, B and C, while the first and second quarters were the epidemic seasons of hepatitis E. The ARIMA model predicted that the monthly incidence rates of viral hepatitis in 2020 would range from 1.26/100 000 to 3.69/100 000, among which hepatitis B ranged from 1.21/100 000 to 2.58/100 000, hepatitis C from 0.20/100 000 to 0.48/100 000, hepatitis E from 0.09/100 000 to 0.25/100 000. Conclusions The incidence of viral hepatitis in Nanjing shows a downward trend. Among different types of hepatitis, hepatitis B has a higher incidence. All types of hepatitis have epidemic seasons. It is predicted that the monthly incidence rates of viral hepatitis will be 1.26/100 000 to 3.69/100 000 in 2020.

Objective To determine whether the adjustment of the pusher of GTF was useful to decrease the degree of tilting of the femoral Ginther Tulip filter (GTF) in an in vitro caval model. Methods The caval model was constructed by placement of a 25 mm × 100 mm and two 10 mm ×200 mm Dacron graft inside a transparent bifurcate glass tube. The study consisted of two groups: left straight group (GLS) (n =100) and left curved group (GLC) (n = 100). In the GLC, a 10° to 20° angle was curved on the introducer.The distance (DCH) between the caval right wall and the hook was measured. The degree of tilting (DT) was classified into 5 grades and recorded. Before and after the GTF being released, the angle (ACM1, 2)between the axis of IVC and the metal mount, the distance (DCM1) between the caval right wall and the metal mount, the angle (ACF) between the axis of IVC and the axis of the filter and the diameter of IVC (DIVC) were measured. The data were analyzed with Chi-Square test, t test, rank sum test and Pearson correlation test. Results The degree of GTF tilting in each group revealed a divergent tendency. In group LC, the apex of the filter tended to be grade Ⅲ compared in group LS (x2 value 37. 491 ,P ＜0.01).The differences of most variables between GLS and GLC were considered as statistical significance(16. 60° vs.3.05°, 20.60° vs. 3.50°, -3.90°vs. -0.40°, 2.98 mm vs. 10.40 mm, - 10.95° vs. -0.485°,13. 17 mm vs. 10.06 mm, - 1.70° vs. 0.70°, t or Z values - 12. 187, - 12. 188, -8.545, -51.834,-11. 395,9. 562, -3. 596, P ＜ 0. 01). There exist significant positive correlation between ACM1 and ACF,ACM1 - ACM2 and DCH1 - DCH2 in each group, respectively(r values 0. 978,0. 344,0. 879,0. 627 ,P ＜0. 01),while significant negative associations are detected between DCH1 and ACF in each group , ACP and ACF in group LC(r values -0.974, -0.322, -0.702,P＜0.01). Conclusion The technique of adjusting the orientation of filter pusher had minimized the incidence and extent of GTF filter tilting in vitro.
