Objective To investigate the effect of HO-1 on acute rejection after orthotopic liver transplantation (OLT) in rats. Methods Taking dark agouti (DA) rats as donors and Lewis rats as recipients, OLT was performed. Before OLT, the DA rats and Lewis rats were matched in pairs, and divided into control group, ZnPP group and CoPP group, the paired rats of which intraperitoneally received normal saline, 20 mg/kg ZnPP and 5 mg/kg CoPP respectively 24 h before OLT. Ten pairs of rats were in each group. On day 3 or 7 after OLT, recipient rats were killed, then blood sample and liver specimen were collected. Plasm levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), albumin (ALB) were measured; HE staining and MPO staining were performed; The expression of HO-1 was detected by the fluorence real time RT-PCR. Results On day 3 and 7 after OLT, AST, ALT and TBIL showed significant statistical significance among the three groups; ALB was highest in CoPP group, then in control group, lowest in ZnPP group. On day 3 after OLT, control group had acute rejection of degree one to degree two, ZnPP group had acute rejection of degree two; CoPP group mainly had acute rejection of degree one; On day 7 after OLT, control group mainly had acute rejection of degree two; ZnPP group had acute rejection of degree two to degree three; CoPP group had acute rejection of degree one to two. The expression of HO-1 was highest in CoPP group, then control group, and lowest in ZnPP group. Conclusion The expression of HO-1 in OLT with acute rejection in rats can palliate the acute rejection.

0.05). Conclusions Gasless laparoscopy is feasible in hysterectomy,especially for the patients complicated with cardiac or pulmonary diseases.

Objective To detect the ocular fundus hemodynamic changes in patients with rhegmatogenous retinal detachment before and after the scleral buckling procedure by Heidelberg retina flowmeter,and analyse the related influential factors. Methods Heidelberg retina flowmeter was employed to measure the volume,flow and velocity in retinal vessels of the impaired eyes in 47 patients with unilateral rhegmatogenous retinal detachments 1 day before and 1 week,1 month and 3 months after scleral buckling procedure.The contralateral eyes were served as controls. ResultsThere were significant differences in the volume,flow and velocity of retinal vessels between the impared eyes and controls preoperation and postoperation(P

Abstract: Objective To explore the relationship between peripheral blood and pleural effusion tuberculosis (TB) infection effector T cells, and to further evaluate the value of combined pleural effusion adenosine deaminase (ADA) for rapid diagnosis of tuberculous pleurisy. Methods The test data of 80 cases of tuberculous pleurisy and 70 cases of nontuberculous pleurisy treated in the Sixth People's Hospital of Nantong City from January 2017 to December 2020 were analyzed. The TBinfected effector T cells were also detected simultaneously in the peripheral blood and the pleural effusion by the T-SPOT technique, and the pleural effusion ADA was detected by the rate method. The subject operating characteristic curve (ROC) was applied to take the optimal pleural effusion ADA threshold to compare the sensitivity and specificity of different critical values. Person phase analysis was applied to analyze the correlation between peripheral blood and pleural effusion T-SPOT.TB. Data of peripheral blood, pleural effusion T-SPOT.TB and ADA were integrated. Results When pleural effusion ADA>45 U/L, the sensitivity and specificity for the diagnosis of tuberculous pleurisy were 50.0% and 94.3%, respectively; when ADA > 25.15 U/ L, the sensitivity and specificity were 80.0% and 72.9%. When ADA > 45 U / L, pleural/ blood T-SPOT.TB spot ratio (spot forming cells, SFCs) > 2 times, the specificity for the diagnosis of tuberculous pleurisy was 100% (highest); when 25.15 U/L< pleural effusion ADA ≤ 45 U/L, pleural/blood T-SPOT.TB spot ratio > 2 times, the specificity for the diagnosis of tuberculous pleurisy was 92.3% (second). When pleural effusion ADA ≤ 25.15 U/L, and the pleural effusion/blood T-SPOT.TB spot number ratio > 2 times, with 83.3% specificity (the lowest of the three groups). Conclusions The level of pleural effusion ADA is one of the most used methods for diagnosing tuberculous pleurisy. Further combination of pleural effusion and blood T-SPOT.TB, if the ratio of pleural effusion / blood T-SPOT. TB spots is greater than 2 times, it can further improve the diagnosis rate of tuberculous pleurisy.

Objective:To prepare compound Xiaoshangtong spray films and establish an HPLC method for quality control. Meth-ods:Chitosan hydrochloride and PVP as the main film-forming materials, and HPMC as the film-forming assitant agent, the com-pound Xiaoshangtong spray films were prepared. Lidocaine and mupirocin were simultaneously determined by HPLC. A Hypersil ODS2 column(250 mm × 4. 6 mm, 5 μm)was used. The mobile phase was composed of 0. 5% ammonium dihydrogen phosphate-methanol (40∶60, adjusting pH to 6. 0 ± 0. 5 with sodium hydroxide). The flow rate of mobile phase was 1. 0 ml·min-1 and the temperature of the column was 30 ℃. The detection wavelength was 222nm and the injection volume was 20 μl. Results: The linear range of lido-caine was 25. 0-400. 0 μg·ml-1(r=0. 999 7) and the average recovery was 100. 14% (RSD=1. 21%,n=9). The linear range of mupirocin was 25.0-400.0 μg·ml-1(r=0.999 9)and the average recovery was 101.13%(RSD=0.57%,n=9). Conclusion:The preparation process is reasonable. The established determination method is accurate and reliable, and suitable for the quality con-trol of the compound Xiaoshangtong spray films.
