Objective: To evaluate the efficacies of lopinavir/ritonavir and abidol in the treatment of NCP. Methods: The clinical data of 134 patients with NCP receiving treatment at Shanghai Public Health Clinical Center during Jan 20 to Feb 6, 2020 were retrospectively collected. All the patients received interferon-α2b spray and symptomatic supportive treatment, and 52 cases received oral lopinavir/ritonavir treatment, 34 cases received oral abidol treatment, the remaining 48 cases did not take any antiviral drugs. The efficacies at median day 7 among the three groups were compared by using Kruskal-Wallis or chi-square tests. Results: The 134 patients included 69 males (51.5%) and 65 females, aged 35-62 years with the average of 48 years. The median time to temperature normalization in patients receiving abidol or lopinavir/ritonavir treatment was both 6 days after admission, and that was 4 days in the control group, with no significant difference (χ²=2.37, P=0.31). The median time to PCR negative in the respiratory specimens in the three groups was all 7 days after admission, and the PCR negative rates at day 7 after admission in lopinavir/ritonavir, abidol and control groups were 71.8% (28/39), 82.6% (19/23) and 77.1% (27/35), respectively, which were not significantly different (χ²=0.46, P=0.79). Radiological worsening at day 7 was observed in comparable proportions of patients in the three groups, which were 42.3% (n=22), 35.3% (n=12) and 52.1% (n=25), respectively (χ²=2.38, P=0.30) . Adverse reactions occurred in 17.3% (n=9), 8.8% (n=3) and 8.3% (n=4) patients, respectively in the three groups (χ²=2.33, P=0.33). Conclusions This study did not find any effects of lopinavir/ritonavir and abidol on relieving symptoms or accelerating virus clearance. The efficacies of these two drugs in NCP treatment need further investigation.

To establish the HPLC-ELSD specific chromatogram analysis method of Rehmanniae Radix and Rehmanniae Radix Prae-parata, and analyze and compare their chemical compositions, so as to reveal the change regularity of compositions during the proces-sing. By HPLC-ELSD method, the chromatographic column for Prevail Carbohydrate ES(4.6 mm ×250 mm, 5 μm) was adopted, with acetonitrile(A)-water(B) as mobile phase for gradient elution, and the evaporative light-scattering detector was used. A total of 23 batches of Rehmannia Radix samples, and 25 batches of Rehmanniae Radix Praeparata samples and processing dynamic samples were compared. The established method had a great repeatability, precision and stability. Eight common chromatographic peaks were extracted from 23 batches of Rehmanniae Radix samples, 8 common peaks were extracted from 25 Rehmanniae Radix Praeparata, and 7 chromatographic peaks were identified. The composition ratio of Rehmannia Radix was changed greatly during the processing. When the simila-rity≥0.95 and the fructose peak area was more than 2 times of stachyose tetrahydrate or more than 20 times of raffinose, the processing degree conformed to the requirements of empirical identification. The three main oligosaccharides of Rehmanniae Radix were sucrose that was heated to generate fructose and glucose, stachyose tetrahydrate that was heated to generate melibiose, sucrose and fructose, and stachyose tetrahydrate that was heated to generate manninotriose. The change in the index of proportion between monosaccharides and oligosaccharides can be used as the quantitative criterion for the processing quality of Rehmanniae Radix Praeparata.

Objective The aim of this study was to analyze the distribution characteristics of CD163+ macrophages in peripheral blood and synovium of patients with osteoarthritis (OA)，and investigate the correlation of CD163+ macrophages, intracellular tumour necrosis factor(TNF-α), interleukin-10 (IL-10) expression with the disease duration, inflammation level and body mass index (BMI). Methods The percentages of CD163+ macrophages in synovium and peripheral blood and their intracellular levels of TNF-α and IL-10 were detected by flow cytometry. Meanwhile, immunofluorescence was uesed to observe the distribution of CD163+ macrophages in synovial tissue of patients with OA or fracture. Results (1) There were significant differences in the percentage of CD163+ macrophages in synovial and peripheral blood between OA and fracture patients(all P<0.05). (2) The expression of TNF-α in CD163+ macrophages of synovium and blood of OA patients with disease duration below 10 years was significantly higher than that of patients with OA disease duration above 10 years (all P<0.05) . The expression of IL-10 was significantly lower than that of patients with OA disease duration above 10 years (all P<0.05). (3) C-reactive protein (CRP) was positively correlated with BMI in patients with OA disease duration below 10 years (r=0.680， P<0.001), while showed no correlation with BMI in patients with OA duration above 10 years(r=0.084， P=0.187). (4) Immunofluorescence confocal microscopy showed a large number of CD163+ macrophages invaded around the synovial vessel of patients with OA. Conclusion The distribution of CD163+ macrophages in synovium and peripheral blood of OA patients with different course of disease was different, and showed differentiated cell subtypes.

OBJECTIVE: To compare the perioperative and oncologic outcomes of female patients receiving laparoscopic radical cystectomy (LRC) and open radical cystectomy (ORC). METHODS: Retrospective review of 91 consecutive female patients with urothelial carcinoma of bladder undergoing radical cystectomy at a single academic institution from 2006 to 2017. Those female patients received open radical cystectomy were matched to the patients who underwent laparoscopic radical cystectomy by using propensity score matching in 1 ∶1 ratio. The matching factors included age, body mass index (BMI), American Society of Anesthesiologists (ASA) score, pathologic stage and pathologic nodal stage. The perioperation and oncology characteristics were compared, and Kaplan-Meier method was used to analyze the overall survival (OS), cancer specific survival (CSS) and progression-free survival (PFS) estimates. Finally, we did a sensitive analysis by using multivariable COX regression of all the patients, adjusting for the matching factors. RESULTS: There were 65 ORC and 26 LRC patients identified in this cohort with urothelial carcinoma of bladder, the median follow-up time was 38 months (interquartile range 18-69). The age (P<0.001) and ASA scores (P=0.018) were less for LRC before being matched. There were 22 LRC and 22 ORC patients matching successfully. Before being matched, the estimate blood loss (P=0.005), transfusion rate (P<0.001) and total complications rate (P=0.015) were less for LRC, and the lymph nodes yield was greater for LRC, but there were no differences in OS (P=0.698), CSS (P=0.942) and PFS (P=0.837) between the two groups. After being matched, the estimate blood loss (P=0.009), transfusion rate (P=0.001) and total complications rate (P=0.040) were less for LRC, but there was no difference in the lymph nodes yield. Besides, there were no statistic differences in OS (P=0.432), CSS (P=0.429) and PFS (P=0.284) between the two groups. In addition, in multivariable COX regression analysis, surgical approaches (LRC/ORC) were not found to be a predictor of OS (HR 1.134, 95%CI 0.335-3.835, P=0.839), CSS (HR 1.051, 95%CI 0.234-4.719, P=0.949) and PFS (HR 0.538, 95%CI 0.138-2.095, P=0.371) of the female patients with urothelial carcinoma of bladder. CONCLUSION It is advantageous for laparoscopic radical cystectomy in terms of estimating blood loss, transfusion rate and complication rate. But there was no evidence that laparoscopic radical cystectomy for female patients with bladder cancer had a better oncologic prognosis than open radical cystectomy from this study.

Fontan surgery is a widely used palliative procedure that significantly improves the survival period of patients with complex congenital heart disease (CHD). However, it does not decrease postoperative complication rate. Previous studies suggested that elevated mean pulmonary artery pressure (mPAP) and vascular resistance lead to decreased exercise tolerance and myocardial dysfunction. Therapy with endothelial receptor antagonists (Bosentan) has been demonstrated to improve the patients' prognosis. A double-blind, randomized controlled trial was performed to explore the efficacy of Bosentan in treating patients who underwent the Fontan procedure. Eligible participants were randomly divided into Bosentan group and control group. Liver function was tested at a local hospital and the results were reported to the phone inspector every month. If the results suggested abnormal liver function, treatment would be adjusted or terminated. All the participants finished the follow-up study, with no patients lost to follow-up. Unblinding after 2-year follow-up, no mortality was observed in either group. However, secondary end-points were found to be significantly different in the comparable groups. The cardiac function and 6-min walking distance in the Bosentan group were significantly superior to those in the control group (P=0.018 and P=0.027). Bosentan could improve New York Heart Association (NYHA) functional status and improve the results of the 6-min walking test (6MWT) in Fontan patients post-surgery, and no other benefits were observed. Furthermore, a primary meta-analysis study systematically reviewed all the similar clinical trails worldwide and concluded an overall NYHA class improvement in Fontan patients who received Bosentan treatments.

This study was aimed to investigate the expression level of Wilms' tumor 1( WT1) gene in hematologic neoplasm (leukemia, multiple myeloma and lymphoma) patients and its clinical significance. Real-time quantitative polymerase chain reaction (RQ-PCR) was used to detect the copy number of WT1 gene and reference gene (ALB) in bone marrow cells of 228 patients with hematologic neoplasm in our hospital. The gene expression level was determined by using the ratio of the copy number of WT1 gene and reference gene. The results showed that the WT1 expression level between male and female patients was not statistically significantly different (P > 0.05). All the patients were divided into 3 groups: the group aged under 19, the group aged between 19-50, and the group aged over 50; the WT1 expression level among the three groups were not statistically significantly different (P > 0.05) . The above-mentioned patients were redivided into the groups aged under 45 and over 45, the difference between them was not statistically significant (P > 0.05). The difference of WT1 expression level between newly diagnosed patients and treated patients with hematologic neoplasm was statistically significant (P < 0.01), but no statistically significant difference of WT1 expression was found (P > 0.05) at each stage within 3 years after treatment, however, among them the difference between newly diagnosed leukemia patients and treated leukemia patients was very statistically significant (P < 0.01), while the difference between newly diagnosed and treated non-leukemia patients was not statistically significant (P > 0.05). The expression difference of WT1 between leukemia and non-leukemia patients was very statistically significant (P < 0.01), the difference between the newly diagnosed leukemia and non-leukemia patients also was very statistically significant (P < 0.01). The difference of WT1 expression between treated leukemia and non-leukemia patients was not statistically significant (P > 0.05). It is concluded that the WT1 expression level in leukemia patients can be a reliable marker to evaluate the prognosis of newly diagnosed leukemia and the curative effect for minimal residual disease. No WT1 expression difference has been found before and after treatment among the patients with non-leukemia, such as multiple myeloma and lymphoma, therefore, which should be furtherly explored.
