ABSTRACT
@#Objective To compare and analyze the efficacy and safety of 5-needle injection and standard 20-needle injection in the treatment of overactive bladder with botulinum toxin type A.Methods A retrospective analysis was performed on 48 patients with overactive bladder who received intravesical injection of botulinum toxin type A in the Department of Urology,Hangzhou Third People's Hospital from January 2015 to December 2022,and they were divided into two groups according to the number of injections,with 24 patients in each group.The observation group received 5-needle injection,and the control group received standard 20-needle injection.Average daily frequency of urination,international consultation on incontinence questionnaire-overactive bladder,international consultation on incontinence questionnaire-overactive bladder(ICIQ-OAB)score,overactive bladder(OAB-Q)score,visual analogue scale(VAS),patient generated index(PGI-I)score,complication rate and willingness to repeat injection were recorded before and after treatment in two groups,respectively.Results There were no significant differences in age,gender,course of disease,average daily frequency of urination before treatment and baseline data of each score between the two groups,which were comparable.All patients completed treatment,and compared with before treatment,the mean daily frequency of urination,ICIQ-OAB and OAB-Q were improved after treatment(P<0.05),there was no significant difference between the two groups(P>0.05).There were no significant differences in scores and incidence of complications between the two groups after treatment(P>0.05).However,patients in the observation group were more willing to receive another injection(P<0.05).Conclusion The efficacy and safety of 5-needle vesical injection of botulinum toxin type A in the treatment of overactive bladder is similar to that of standard 20-needle injection,which is more easily accepted by patients,and is a safe and effective alternative to standard technique.
ABSTRACT
Currently,human health due to corona virus disease 2019(COVID-19)pandemic has been seriously threatened.The coronavirus severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)spike(S)protein plays a crucial role in virus transmission and several S-based therapeutic approaches have been approved for the treatment of COVID-19.However,the efficacy is compromised by the SARS-CoV-2 evolvement and mutation.Here we report the SARS-CoV-2 S protein receptor-binding domain(RBD)inhibitor licorice-saponin A3(A3)could widely inhibit RBD of SARS-CoV-2 variants,including Beta,Delta,and Omicron BA.1,XBB and BQ1.1.Furthermore,A3 could potently inhibit SARS-CoV-2 Omicron virus in Vero E6 cells,with EC50 of 1.016 pM.The mechanism was related to binding with Y453 of RBD deter-mined by hydrogen-deuterium exchange mass spectrometry(HDX-MS)analysis combined with quan-tum mechanics/molecular mechanics(QM/MM)simulations.Interestingly,phosphoproteomics analysis and multi fluorescent immunohistochemistry(mIHC)respectively indicated that A3 also inhibits host inflammation by directly modulating the JNK and p38 mitogen-activated protein kinase(MAPK)path-ways and rebalancing the corresponding immune dysregulation.This work supports A3 as a promising broad-spectrum small molecule drug candidate for COVID-19.

ABSTRACT
Consecutively hospitalized patients with confirmed coronavirus disease 2019 (COVID-19) in Wuhan, China were retrospectively enrolled from January 2020 to March 2020 to investigate the association between the use of renin-angiotensin system inhibitor (RAS-I) and the outcome of this disease. Associations between the use of RAS-I (angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB)), ACEI, and ARB and in-hospital mortality were analyzed using multivariate Cox proportional hazards regression models in overall and subgroup of hypertension status. A total of 2771 patients with COVID-19 were included, with moderate and severe cases accounting for 45.0% and 36.5%, respectively. A total of 195 (7.0%) patients died. RAS-I (hazard ratio (HR)= 0.499, 95% confidence interval (CI) 0.325-0.767) and ARB (HR = 0.410, 95% CI 0.240-0.700) use was associated with a reduced risk of all-cause mortality among patients with COVID-19. For patients with hypertension, RAS-I and ARB applications were also associated with a reduced risk of mortality with HR of 0.352 (95% CI 0.162-0.764) and 0.279 (95% CI 0.115-0.677), respectively. RAS-I exhibited protective effects on the survival outcome of COVID-19. ARB use was associated with a reduced risk of all-cause mortality among patients with COVID-19.

ABSTRACT
Objective:To investigate the expression of programmed death ligand 1 (PD-L1) in rectal cancer tissues and the correlation of PD-L1 expression with clinicopathological characteristics and overall survival of patients.Methods:The clinical data of 200 newly treated rectal cancer patients in Shanxi Provincial Cancer Hospital from January 2014 to December 2015 were retrospectively analyzed. The expression of PD-L1 in rectal cancer tissues was detected by immunohistochemistry. The correlations of PD-L1 expression with gender, age, tumor T stage, lymph node metastasis, tumor differentiation, histological type, tumor TNM stage, neutrophil-to-lymphocyte ratio (NLR) and overall survival of patients were analyzed.Results:The positive expression rate of PD-L1 was 24% (48/200). The positive expression rate of PD-L1 was high in patients with lymph node metastasis and high NLR (≥ 3.5) (both P < 0.05). The 5-year overall survival rate in PD-L1-positive group was 42%, and the PD-L1-negative group was 59%, and the difference between the two groups was statistically significant ( P < 0.05). The results of multivariate analysis showed that lymph node metastasis ( HR = 3.456, 95% CI 2.148-5.556, P < 0.01), NLR ≥ 3.5 ( HR = 1.871, 95% CI 1.169-2.996, P = 0.009), and PD-L1-positive expression ( HR = 2.187, 95% CI 1.373-3.484, P = 0.001) were independent adverse influencing factors for the overall survival of rectal cancer patients. Conclusion:PD-L1 is highly expressed in rectal cancer tissues, and the positive expression of PD-L1 is associated with poor overall survival of patients.

ABSTRACT
In the past ten years, the research and application of microbiome has continued to increase. The microbiome has gradually become the research focus in the fields of life science, environmental science, and medicine. Meanwhile, many countries and organizations around the world are launching their own microbiome projects and conducting a multi-faceted layout, striving to gain a strategic position in this promising field. In addition, whether it is scientific research or industrial applications, there has been a climax of research and a wave of investment and financing, accordingly, products and services related to the microbiome are constantly emerging. However, due to the rapid development of microbiome sequencing and analysis related technologies and methods, the research and application from various countries have not yet unified on the standards of technology, programs, and data. Domestic industry participants also have insufficient understanding of the microbiome. New methods, technologies, and theories have not yet been fully accepted and used. In addition, some of the existing standards and guidelines are too general with poor practicality. This not only causes obstacles in the integration of scientific research data and waste of resources, but also gives related companies unfair competition opportunity. More importantly, China still lacks national standards related to the microbiome, and the national microbiome project is still in the process of preparation. In this context, the experts and practitioners of the microbiome worked together and developed the consensus of experts. It can not only guide domestic scientific research and industrial institutions to regulate the production, learning and research of the microbiome, the application can also provide reference technical basis for the relevant national functional departments, protect the scale and standardized corporate company's interests, strengthen industry self-discipline, avoid unregulated enterprises from disrupting the market, and ultimately promote the benign development of microbiome-related industries.

Objective:To investigate the effect of high mobility group box-1 protein (HMGB1)-nuclear factor-κB (NF-κB) signaling pathway on autophagy and chemosensitivity of human hepatocellular carcinoma cells and its possible mechanism.Methods:Human hepatocellular carcinoma BEL-7402 cells were cultured in vitro and divided into control group (BEL-7402 cells without any treatment), doxorubicin group, recombinant human HMGB1+doxorubicin group, anti-HMGB1 neutralizing antibody+doxorubicin group, pyrrolidine dithiocarbamate+doxorubicin group and 3-methyladenine + doxorubicin group. The methyl thiazolyl tetrazolium (MTT) method was used to detect cell proliferation inhibition rate. Western blot method was used to detect the expressions of HMGB1 and NF-κB subunit p-p65 protein, the autophagy-related proteins Beclin-1, LC3Ⅰ, LC3Ⅱ and apoptosis-related protein bcl-2. Enzyme labeling method was used to detect Caspase-9 and Caspase-3 activity.Results:The cell proliferation inhibition rates in the control group, doxorubicin group, recombinant human HMGB1+doxorubicin group, anti-HMGB1 neutralizing antibody+doxorubicin group, pyrrolidine dithiocarbamate+doxorubicin group and 3-methyladenine+doxorubicin group were (1.31±0.16)%, (47.80±6.30)%, (31.60±5.68)%, (67.20±6.83)%, (66.60±6.27)%, and (68.60±11.19)%, respectively, and the difference was statistically significant ( F = 75.91, P < 0.01), suggesting that doxorubicin had a proliferation inhibitory effect on BEL-7402 cells; the expression levels of HMGB1 were 1.17±0.11, 1.37±0.15, 1.43±0.15, 0.70±0.09, 1.27±0.12, 1.29±0.18, and the difference was statistically significant ( F = 18.70, P < 0.01), suggesting that doxorubicin could increase the expression of HMGB1 in BEL-7402 cells, and the anti-HMGB1 neutralizing antibody could block or attenuate this effect; after pretreatment with recombinant human HMGB1, the proliferation inhibitory effect of doxorubicin on BEL-7402 cells was weakened; after pretreatment with anti-HMGB1 neutralizing antibody, pyrrolidine dithiocarbamate and 3-methyladenine, the proliferation inhibitory effect of doxorubicin on BEL-7402 cells was enhanced. Compared with the control group, the expression of p-p65 protein in the doxorubicin group, recombinant human HMGB1+doxorubicin group and 3-methyladenine+doxorubicin group increased (all P < 0.05). The expression of p-p65 protein in the recombinant human HMGB1+doxorubicin group, anti-HMGB1 neutralizing antibody+doxorubicin group and pyrrolidine dithiocarbamate+doxorubicin group was lower than that in the doxorubicin group (all P < 0.05). Compared with the control group, the expression of bcl-2 protein in doxorubicin group, anti-HMGB1 neutralizing antibody+doxorubicin group, pyrrolidine dithiocarbamate+doxorubicin group and 3-methyladenine+ doxorubicin group decreased (all P < 0.05), and the activity of Caspase-9 and Caspase-3 was enhanced (all P < 0.05); after adding recombinant human HMGB1 pretreatment, the expression of bcl-2 protein in the cells increased compared with doxorubicin alone, and the activity of Caspase-9 and Caspase-3 was weakened (all P < 0.05). The expression levels of autophagy-related protein Beclin-1 in the control group, doxorubicin group, recombinant human HMGB1+doxorubicin group, anti-HMGB1 neutralizing antibody+doxorubicin group, pyrrolidine dithiocarbamate+doxorubicin group, and 3-methyl adenine+doxorubicin group were 0.77±0.12, 0.92±0.07, 1.29±0.10, 0.51±0.03, 0.49±0.06, and 0.42±0.05, and the difference was statistically significant ( F = 97.01, P < 0.01). The expression levels of LC3Ⅱ were 0.24±0.04, 0.39±0.04, 0.49±0.07, 0.23±0.05, 0.20±0.06, and 0.20±0.05, and the difference was statistically significant ( F = 26.98, P < 0.01). Conclusion:The activation of HMGB1-NF-κB signaling pathway can reduce the chemosensitivity of hepatocellular carcinoma cells to doxorubicin, and its mechanism may be related to the regulation of autophagy and down-regulation of doxorubicin inducing apoptosis of hepatocellular carcinoma cells.
ABSTRACT
Objective@#To study the mechanism of baicalin in inhibiting Mycobacterium tuberculosis(MTB)and to provide reference for drug-resistant tuberculosis treatment.@*Methods@#Forty male Kunming mice were injected isoniazid-resistant MTB into their tail veins to build models of infection. They were evenly divided into MTB group,isophosiazone group,NF-κB inhibition group and baicalicin group according to treatment. The lung tissue and peripheral blood of the mice were collected on the 8th day after modeling. The morphological changes of the lungs were observed by HE staining. The number of MTB in lung tissue was detected by acid-fast staining and quantitative PCR. The number of macrophagein lung tissue was detected by immunohistochemistry. The expression of NF-κB and TLR4 in monocytes/macrophages were detected by flow cytometry. @*Results@#The average weight of mice in the baicalicin group was significantly higher than that in the MTB group,the isophosiazone group and the NF-κBinhibition group(P<0.05). The average fluorescence intensity of NF-κB and TLR4 in monocytes/macrophages in the baicalicin group were 448.21±30.61 and 401.01±34.58,which were significantly higher than those in the MTB group and the isophosiazone group(P<0.05). Typical tuberculous chronic granulomatous lesions were observed in the MTB group,isophosiazone group and NF-κB inhibition group,except the baicalin group. The mean number of MTB and CD68+ macrophagesin lung tissue of mice in the baicalin group were significantly less than that in the MTB group,the isophosiazone group and the NF-κB inhibition group(P<0.05). @*Conclusion@#Baicalin achieves an anti-tuberculosis effect by regulating the expression of NF-κB and TLR4 in macrophages,which can be weakened by adding NF-κB inhibitor.

ABSTRACT
Background and purpose:Bladder cancer is the most common urological tumor, and its pathogen-esis is still not fully understood. The study was aimed to observe the expressions of key genes in many tumor-associated signaling pathways in normal bladder tissue and bladder carcinoma, and to provide further evidence for the subsequent study of bladder cancer recurrence and metastasis.Methods:Twenty-seven cases of bladder cancer specimens were col-lected, and normal bladder tissues and bladder cancer tissues were distinguished by frozen section. Then, the expressions of 84 genes of cancer-related signaling pathways in bladder cancer tissues and normal bladder tissues were screened by Cancer Pathway Finder PCR Array produced by QIAGEN company.Results:Compared with the normal bladder tissues, the bladder carcinoma tissues had 8 up-regulated genes and 19 down-regulated genes. In this study, the impact of epithe-lial-mesenchymal transition (EMT) signaling pathway was selected as a research direction in which theGSC,KRT14,DSP were up-regulated,SNAI2,SNAI3 were down-regulated. ThereforeGSC,KRT14,DSP,SNAI2 andSNAI3 were chosen as target genes, and verified by qRT-PCR in many examples. The result showed that the expressions ofGSC gene in bladder cancer tissues were up-regulated, but with no statistical significance;KRT14,DSP expressions in bladder cancer were higher than those in normal bladder tissues (P<0.05);SNAI2,SNAI3 expressions in bladder cancer were lower than those in normal bladder tissues (P<0.05), andSNAI3 showed the most obvious expression differences.Conclusion:KRT14,DSP andSNAI3 may play an important role in bladder cancer’s occurrence, development and metastasis.
