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.

By retrieving the clinical research literature of treatment functional dyspepsia by traditional Chinese medicine (TCM) from January 2004 to December 2014 based on China National Knowledge Internet (CNKI), we would establish a TCM decoction database for treating functional dyspepsia in this study. One hundred and sixty-four literature were included, involving 159 prescriptions, 377 medicines, in a total of 1 990 herbs. These herbs can be divided into 18 categories according to the effectiveness; and qi-regulating herbs, blood circulation herbs, and antipyretic herbs ranked top three ones according to the frequency of usage of the herbs, whose medicine usage frequency accounted for 51.81%. Usage frequency of 16 herbs was over 30, and Atractylodes, Radix, Poriaranked top three according to the usage frequency. Medicinal properties were divided into 9 kinds according to the frequency statistics, and the top three were warm, flat, and cold. Taste frequency statistics were classifiedinto 9 kinds, and the top three were acrid, sweet, and bitter. In frequency statistics of the meridian tropism of herbs, it was classifiedinto 11 kinds, and the top three were spleen, stomach, lung. The analysis can provide a reference for treatment and study of TCM of functional dyspepsia.

Gindenosides are the active ingredients of Panax ginseng. 20 (S) -protopanaxadiolocotillol type epimers are the main metabolites of 20 (S) -protopanaxadiol. The previous studies showed that there are stereoselectivity difference in pharmacodynamics and pharmacokinetics between 24R-epimer and 24S-epimer. The purpose of this study was to explore the excretion of the epimers in bile, feces and urine of rat. Liquid chromatography tandem mass spectrometry method has been performed for determination of 24R-epimer and 24S-epimer in bile, feces and urine. 24R-epimer or 24S-epimer was intragastric administered to rats at a single dose of 10 mg x kg(-1). Results showed that after administration the recovery of 24R-epimer and 24S-epimer in feces was 17.69% and 17.09%, respectively, while both of the two epimers were hardly detected in urine. The 48 h cumulative biliary excretion rate of 24R-epimer was 8.01% after administration, while only 1.47% for 24S-epimer. It indicated that there are stereoselectivity in biliary excretion of the epimers with intragastric administration.

Background Retinal angiomatous proliferation (RAP) is a subtype of neovascular age-related macular degeneration (AMD).There are currently very few studies on RAP.Objective This study was to explore the pathogenic mechanism of RAP in apolipoprotein E-deficient (ApoE-/-) mice with dyslipidemia.Methods Twenty-four 2-month-old SPF ApoE-/-mice were randomly divided into the high fat diet group and the normal diet group,and twelve 2-month-old C57BL/6 mice received the normal diet as controls.A diet with a higher content of fat was given for 4 consecutive months in the high fat diet group,and normal diet was given in the same way in the mice of the normal diet group.The mice were sacrificed at 6 months of age.The expression of vascular endothelial growth factor (VEGF) in the retinal pigment epithelial (RPE) cells,the expression of vascular endothelial growth factor receptor-2 (VEGFR-2) in the outer plexiform layer (OPL),microvascular density (MVD) and microvascular area (MVA) in the OPL were examined by immunohistochemistry and semi-quantitatively by histopathology with the Mias 2000 Imaging Analyzer System.The expression of VEGF protein in the retina was examined by Western blot.Results The MVD in the retinal OPL were (20.67±3.20) and (19.50± 1.87),respectively,in the ApoE-/-mice of the high fat diet group and the normal diet group,which were significantly higher than that (12.50±1.87) of the C57BL/6 normal diet group (all at P＜0.01).MVA in the retinal OPL were (626.49± 120.99) μm2 and (514.06±88.83) μm2 in the ApoE-/-mice of the high fat diet group and the normal diet group,respectively,showing a significant increase in comparison with the (336.52±84.96) μm2 of the C57BL/6 normal diet group (P＜0.01).The staining area of VEGF in RPE cells was (21 048±1849) μm2 in the ApoE-/-mice of the high fat diet group,showing a significant increase in comparison with the (17 116±2023) μm2 of the C57BL/6 normal diet group.However,no significant difference was found in the staining area of VEGF between the ApoE-/-mice with normal diet group and the C57BL/6 normal diet group ([17 854±2967] μm2 vs.[17 116±2023] μm2) (P＞0.05).Significant elevation was also seen in the staining area of VEGFR-2 in the retinal OPL of the ApoE-/-mice of the high fat diet group (12 193±3806)μm2 and the ApoE-/-mice of the normal diet group (11 969± 3616)xm2 compared with C57BL/6 mice of the normal diet group (5387±2225)μm2(all at P＜0.01).The relative expression values (VEGF/β-actin) of VEGF in the retinas were (1.51 ±0.32) and (1.17±0.39) in the ApoE-/-mice of the high fat diet group and the normal diet group,respectively,showing a significant increase in comparison with (0.28±0.14) of the C57BL/6 normal diet group (P＜0.01).Conclusions The expression of VEGF and VEGFR-2 in the retinas increases in the ApoE-/-mouse,which leads to the enlargement of MVD and MVA in the retinal OPL and subsequent RAP occurrence.

Objective To investigate the correlation between de nove anti-endothelial cell antibodies (AECA) and adverse events after renal transplantation and the effect of transplanted renal function within six months after operation.Methods The expression of AECA in serum of 85 renal transplant recipients was detected by indirect immunofluorescence assay (ⅡF) before and 1 day,3 days,7 days,15 days and 1 month after renal transplantation.The patients were divided into double positive group (AECA positive before and after surgery),single positive group (postoperative de nove AECA positive) and negative group (preoperative and postoperative AECA negative) according to AECA test results.The occurrence of adverse events in each group such as DGF,rejection,infection and so on,as well as the serum creatinine levels were recorded at each time point within six months.Results Of the 85 recipients,29 were positive for AECA,including 19 in the double positive group,10 in the single positive group,and 56 in the negative group.The incidence of rejection in single positive group (30％) was higher than that in the rest two groups (5.3％ for double positive group,and 17.9％ for negative group),but there was no statistically significant difference (P =0.21).The incidence of DGF in the single positive group,double positive group and negative group was 70.0％,26.3 ％ and 32.1 ％ respectively.The positive rate of the single positive group was significantly higher than that of the rest two groups (P =0.04),and the duration of DGF was significantly longer in the single positive group than that of the rest two groups (P＜0.01).The incidence of infection in the single positive group,double positive group and negative group was 20.0％,21.1％ and 8.9％respectively,and there was no significant difference among the three groups (P =0.31).As compared with the double positive group and the negative group,the serum creatinine level was significantly increased in the single positive group at 1st week,1st month,3rd month and 6th month after operation (P =0.02,P =0.04,P =0.04 and P =0.02 respectively).Conclusion Postoperative AECA can increase the risk of DGF,prolong the duration of DGF,and affect the recovery of renal function within 6 months after renal transplantation.
