Objective To study the effect and safety of controlled-release dinoprostone on the induced labor of late pregnancy . Methods 60 cases of late pregnancy puerpera were treated in our hospital from February 2014 to September 2015, and divided into the control group and the experimental group with reference to the stochastic indicator method, 30 cases in each group. The control group were given induced labor by oxytocin, and the experimental group were given induced labor by controlled-release dinoprostone, Changes of Bishop score, effects of promoting cervical mature, induced labor situation, and adverse reaction were compared between two groups. Results After medication, the cervical Bishop score of the group (8.35±0.93) points were significantly higher than (6.64±0.72) of the control group (P<0.05). The total effective rate 96.67％(29/30) of promoting cervical mature in the experimental group was significantly higher than 80.00％ (24/30) of the control group (P<0.05). Medicine to clinical time (14.89±1.57)h and total labor time (6.94±1.52) h of the experimental group were significantly better than (21.48±2.35) h and (9.30±1.31) h of the control group (P<0.05). The rate of delivery by vagina of the experimental group 83.33％ (25/30) was significantly higher than 60.00％ (18/30) of the control group (P<0.05). There was no different on adverse reaction rate between two groups. Conclusion There was good effects of Controlled-release dinoprostone on the induced labor of later pregnancy, with high rate of delivery by vagina and better safety.

Diabetic retinopathy (DR) is one of the most common and serious diabetic complications, which is the main cause of vision loss in adults. The specific vascular and neuropathology mechanism of DR is not clear. It has been demonstrated that Inflammatory reaction might be take effects in the development and progression of DR. Monocyte chemoattractant protein-1 (MCP-1), as an important chemokine in the inflammatory response process, promotes chemotactic and activating factors, destroys the blood-retinal barrier, causes retinal vascular disease, and activates microglia, which is related to the severity of the disease. With further research on MCP-1, it is possible to use chemokines and their receptors as target cells to control or slow down the progression of DR by reducing or inhibiting the production of MCP-1 in diabetic patients in the early stages of the disease. This study can provide new ideas and new methods about preventing and treating DR.

[Objective] To investigate the effect of naringin at different doses on the neuropathie pain produced by lumbar 5 spinal nerve ligafion (L5 SNL). [Methods] Using the method of behavioral test, we tested the 50% paw withdrawal threshold before and after intragastrieal application of naringin in the rats with L5 SNL. [Results] Naringin at 30, 90, 100 mg/kg but not at 10 mg/kg increased the 50% paw withdrawal threshold of 1.5 SNL rats significantly. Single application of Naringin (at 30 or 90 mg/kg) inhibited mechanical allodynia for around 6 hours, and the inhibitory effect persisted for 4 days after the cessation of the drug when naringin (30 mg/kg, daily) was consecutively applied for 7 days. [Conclusion] Intragastrical of naringin could relieve the neuropathic pain produced by peripheral nerve injury.

OBJECTIVETo observe the effect of Shen warming Pi strengthening method on expressions of serum T cell subsets (C045+%, C03+%, and C04 +/COB+) in diarrhea-predominant irritable bowel syndrome (IBS-0) rats. Methods An IBS-0 rat model was established referring to AL-Chaer's modeling method combined with tail clamp and intragastric administration of sanna leaf. After modeling 30 SO rats were randomly divided into 6 groups according to random digit table, i.e., the model group, the high, middle, low dose Wenshen Jianpi Recipe (WJR) groups, and the Sishen Pill control group, 6 in each group. A normal control group consisting of 6 SO rats were also set up. Rats in high, middle, low dose WJ R groups were administered by gastrogavage with boil-free WJ R at the daily dose of 3. 100, 1. 550, 0. 775 g/kg, respectively. Rats in the Sis hen Pill control group were administered by gastrogavage with boil-free Sis hen Pill at the daily dose of 0. 736 g/kg. Equal volume of normal saline was given by gastrogavage to rats in the model group and the normal control group. All medication lasted for 2 successive weeks. Rats' general state, expressions of T cell subsets (CD45+%, CD3+%, and CD4+ /CDB+) changes were observed.

RESULTSCompared with the normal control group, expressions of CD45+% and CD3+% increased, but CD4+ /CDB+ decreased with statistical difference (P < 0. 05). Compared with the model group, expressions of CD45+% and CD3+% decreased, but CD4+ ICDB+ increased with statistical difference in high, middle, low dose WJR groups, and the Sis hen Pill control group (P <0. 05). Compared with the Sis hen Pill control group, there was statistical difference in all indices except CD45+ value in the low dose SWPSM group (P <0. 05). Compared with the low dose WJ R group, the expression of CD3+% decreased in high and middle dose WJR groups, and the Sis hen Pill control group; CD4+ /CD8+ increased in the Sishen Pill control group and the high dose SWPSM group (all P < 0. 05).

CONCLUSIONSWJR showed better treatment effect. The mechanism of Shen warming Pi strengthening method might be achieved by regulating expressions of CD45+% and CD3+%, and CD4+ /CD8+ ratios.

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.

Background and purpose:Researches had indicated that about over 85%of malignant tumors highly express telomerase activity. So telomerase has become one of the important methods in the research field of tumor diagnosis and treatment. Nowadays, several reports about malignant tumor which over expresses hTERT targeting imaging with radionuclide labeled hTERT ASON had been published. In these reports, high quality of pictures can hardly be acquired because of poor anatomical and spacial resolution in nuclear imaging itself. Accordingly, in this study, we developed a method of detecting human telomerase in vivo with magnetic resonance imaging (MRI) and evaluate its feasibility. Methods:Firstly, Uniformly phosphorothioate-modified human telomerase reverse transcriptase antisense oligonucleotide (hTERT ASON) was labeled with Gd3+ through the bifunctional chelator 1, 4, 7, 10-tetraazacyclododecane-N, N’, N’’, N’’’-tetraacetic acid (DOTA) and iv vitro experiments were performed to characterize the antisense probes (for biodistribution and cellular uptake, 99mTc-DOTA-ASON was used in stead of Gd-DOTA-ASON). Then Gd-DOTA-ASON was injected intraperitoneally in pulmonary adenocarcinoma A375 nude mice tumor-bearing BALB/c for in vivo imaging using 7.0 T Micro MRI periodically, tumors and their surrounding tissues were defined as region of interest (ROI) to calculate the signal to noise ratio (SNR) of tumor to muscle using Gd-DTPA as control. Finally, immunohistochemical analysis of telomerase activity of each xenograft was operated 2 days after imaging. Results:The binding efficiency of Gd-DOTA-ASON reached was as high as 65%(63.2±2.4, n=6). And it can maintain 61%in fresh human serum and normal saline at 37℃over 24 h;A375 cells showed an uptake of 8.5%when incubated with 99mTc-DOTA-ASON;In comparing with DOTA-ASON and Gd-DTPA, cells transected with Gd-DOTA-ASON had higher SI when performed MRI with T1WI. The hTERT-expressing xenografts were obviously enhanced by Gd-DOTA-ASON at 0.5-6 h after injection and the SNR can reach 2.37, whereas obvious enhancement only could be found within 2 h after injection of Gd-DTPA. Both labeled and non-labeled antisense probes can suppress the activity of telomerase of A375 cells either in vitro or in vitro. Conclusion:Our research offers proof that Gd-DOTA-ASON can be used as tumor specific targeting MR probe for diagnosing malignant tumors with high expression of telomerase.
