In 2022, American Urological Association updated the guideline for the diagnosis and treatment of interstitial cystitis/bladder pain syndrome (IC/BPS). A significant change has been made in treatment recommendations. The updated guideline no longer divided treatments into first-line through sixth-line tiers. Instead, treatment is categorized into behavioral/non-pharmacologic, oral medicines, bladder instillations, procedures, and major surgery. This change emphasizes the heterogeneity of IC/BPS patients and the importance of individualized treatment, overturns traditional unreasonable ideas about hierarchical and progressive treatment, and encourages patients and physicians to make treatment decisions together. At the same time, the panel emphasized the importance of early implementation of cystoscopy in patients suspected of Hunner lesions and warned against the possibility of pentosan polysulfate causing a unique retinal pigmentary maculopathy. Urinary reconstruction surgery was considered to only be used as a last resort for the treatment of IC/BPS, and there is uncertainty about the overall balance between benefits and risks/burdens. The updated guideline provides a new understanding and decision-making basis for the diagnosis and treatment of IC/BPS. However, it should be noted that the clinical characteristics of Chinese patients should be considered in practice and the application of the guideline should be localized.

Objective:To evaluate the clinical efficacy of five different Chinese patent medicines combined with conventional western medicine therapy in the treatment of coronary heart disease with anxiety and depression.Methods:Randomized controlled trials (RCTs) of Chinese patent medicine combined with conventional western medicine therapy and conventional western medicine therapy in the treatment of coronary heart disease with anxiety and depression were retrieved from China Academic Journal Database (Wanfang Data), China Biomedical Literature Service System (SinoMed), China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Journal Database (Chongqing VIP), Cochrane Library, PubMed and Embase databases from January 1, 2010 to December 31, 2020. The Jadad score and Cochrane bias risk assessment tool were used to assess the bias risk of the included literature. The RevMan 5.3, Stata 16.0 and GeMTC 14.3 software were used for network meta-analysis.Results:A total of 32 articles involving 3 494 patients were included. In terms of clinical efficacy, the clinical efficacy of conventional western medicine combined with Zhenyuan Capsule [ OR (95% CI)=16.64 (6.38, 43.44)], Xinkeshu Tablets [ OR (95% CI)=4.67 (3.26, 6.68)], Wuling Capsule [ OR (95% CI)=4.65 (2.48, 8.72)], Guanxinjing Capsule [ OR (95% CI)=2.93 (1.37, 2.64)] weres better than that of conventional western medicine alone. The clinical efficacy of combined Zhenyuan Capsule was better than that of combined Xinkeshu Tablets [ OR (95% CI)=3.56 (1.28, 9.94)], Wuling Capsule [ OR (95% CI)=3.58 (1.13, 11.34)], Guanxinjing Capsule [ OR (95% CI)=5.69 (1.68, 19.32)] or Shugan Jieyu Capsule [ OR (95% CI)=9.29 (2.79, 30.96)]. Compared with Shugan Jieyu Capsule, Xinkeshu Tablets had better clinical efficacy [ OR (95% CI)=2.61 (1.16, 5.87)]. The SUCRA order of the effective rate of clinical efficacy was as follows conventional western medicine treatment combined with Zhenyuan Capsule (SUCRA=99.6)>with Xinkeshu Tablets (SUCRA=67.5) > with Wuling Capsule (SUCRA=65.0) > with Guanxinjing Capsule (SUCRA=41.6) > with Shugan Jieyu Capsule (SUCRA=25.8)>conventional western medicine treatment (SUCRA=0.5). Combined Xinkeshu Tablets [ MD (95% CI)=-8.85 (-14.16, -3.62)] was superior to conventional western medicine in reducing HAMD score. In terms of reducing HAMA score, compared with conventional western medicine therapy, the combination of Wuling Capsule [ MD (95% CI)=-7.61 (-14.82, -0.40)] and Xinkeshu Tablets [ MD=-6.18, 95% CI (-9.78, -2.58)] has better curative effect. The SUCRA of Chinese patent medicine in reducing HAMA of coronary heart disease complicated with anxiety and depression was combined with Wuling Capsule (SUCRA=82.8) > with Xinkeshu Tablets (SUCRA=78.2). In terms of adverse reactions, the safety of combined five Chinese patent medicines was better than that of conventional western medicine. Conclusions:The clinical efficacy and safety of conventional western medicine combined with five kinds of Chinese patent medicines in the treatment of coronary heart disease complicated with anxiety and depression were better than those of conventional western medicine alone. Among them, the combination of Zhenyuan Capsule was the most likely to be the best treatment. The combination of Xinkeshu Tablets was better in reducing HAMD scores, and the combination of Xinkeshu Tablets and Wuling Capsule is better in reducing HAMA scores. More high-quality RCT studies are needed to verify the conclusions.

Objective:To retrospectively analyze the blood leukocytes (WBC), lymphocytes (LYM), lymphocyte% (LYM%), and serum total immunoglobulin (IGA, IGG, IGM) and complement (C3, C4) index levels to explore its predictive value for the outcome of COVID-19 severe pneumonia.Methods:Eighty-five COVID-19 patients with severe pneumonia diagnosed in our hospital were randomly selected and were divided into good outcome group (50 cases) and poor outcome group (35 cases). WBC, LYM, LYM%, IGA, IGG, IGM, and C3, C4 level data, and analyze the differences between the two groups, the correlation of each indicator, and ROC curves of single and joint detection to explore relationship between indicators and outcomes, and the predictive efficacy of indicators on outcomes.Results:Differences in WBC, LYM, LYM%, IGG, and IGA levels were significant between the two groups ( P=0.000, 0.015, 0.000, 0.000, 0.001), among them with significant differences, LYM and LYM% were significantly positively correlated ( r=0.669, P=0.000), while WBC and LYM% levels were significantly negatively correlated ( r=-0.600, P=0.000), WBC and IGA levels were significantly positively correlated ( r=0.283, P=0.009) and IGG and IGA levels were also significantly positively correlated ( r=0.0.442, P=0.000); After logistic regression analysis, WBC, LYM, LYM%, IGG, and IGA are all important influencing factors ( P=0.001, 0.022, 0.000, 0.000, 0.003); but only the levels of WBC, IGG, and LYM% are Independent risk factors ( P=0.034, 0.004, 0.001), the ROC curve of the single detection and joint detection of their predicted outcome performance, respectively, and the max AUC (AUC=0.890, P=0.000) at the time of joint testing of WBC, LYM% and IGG, index YI=0.657, it has the greatest predictive power for adverse outcomes, with a sensitivity of 77.10% and a specificity of 88.00%. IGM, C3, C4, IGG/IGM, and C3/C4 levels were not significantly different( P=0.066, 0.204, 0.076, 0.310, 0.156). Conclusions:The levels of WBC, LYM, LYM%, IGG, and IGA in the early admission of COVID-19 infected patients with severe pneumonia have important predictive value for the outcome of them. WBC, LYM% and IGG levels are independent risks and joint detection of the three indexes have the best predictive performance.

Objective: To understand the possible transmission route of a family cluster of COVID-19 in Zhengzhou and the potential infectivity of COVID-19 in incubation period, and provide scientific evidence for the timely control of infectious source and curb the spread of the epidemic. Methods: Epidemiological investigation was conducted for a family cluster of COVID-19 (8 cases) with descriptive epidemiological method, and respiratory tract samples of the cases were collected for the nucleic acid detection of 2019-nCoV by RT-PCR. Results: Two primary cases, which occurred on 31 January and 1 February, 2020, respectively, had a common exposure history in Wuhan. The other six family members had onsets on 30 January, 31 January, 1 February (three cases) and 3 February, 2020. Conclusions In this family cluster of COVID-19, six family members were infected through common family exposure to the 2 primary cases. Five secondary cases had onsets earlier than or on the same day as the primary cases, indicating that COVID-19 is contagious in incubation period, and the home isolation in the early phase of the epidemic might lead to the risk of family cluster of COVID-19.

To determine the value of radiomics in identifying lymph node (LN) metastasis in patients with rectal nonmucinous adenocarcinoma.
 Methods: Imaging data of 91 patients were retrospectively analyzed (61 in the training set and 30 in the test set). A total of 1 301 radiomics features were extracted from high-resolution T2-weighted images of the whole primary tumor. The least absolute shrinkage and selection operator (LASSO) logistic regression was performed to choose the optimal features and construct a radiomics classifier in the training set. Its discrimination performance was compared with that of morphological criteria by receiver operating characteristic (ROC) curve analysis, which was validated in the test set.
 Results: The radiomics classifier combined with five key features was significantly associated with LN metastasis, which distinguished LN metastasis with an area under curve (AUC) at 0.874 (95% CI 0.787 to 0.960) in the training set, and the performance was similar in the test set (AUC 0.878, 95% CI 0.727 to 1.000). The AUCs according to the morphological criteria in the training set and test set were 0.619 (95% CI 0.487 to 0.752) and 0.556 (95% CI 0.355 to 0.756), respectively. Discrimination of the radiomics classifier was superior to that of morphological criteria in both the two datasets (both P <0.05).
 Conclusion: The radiomics classifier provides individualized risk estimation for LN metastasis in rectal nonmucinous adenocarcinoma patients and it has the advantage over the morphological criteria.

Objective: To investigate the clinical value of combined detection of serum angiopoietin 2 (Ang-2) and Clara cell protein 16 (CC16) in the early diagnosis of acute respiratory distress syndrome (ARDS). Methods: Two hundred critical patients, treated at the Department of Critical Care Medicine, Bao'an District People's Hospital, Shenzhen during March 2015 and September 2016,were included in the study. According to the Berlin standard, patients were divided into two groups (n=100 each group): the ARDS group and non-ARDS group.The serum levels of Ang-2 and CC16 were measured by enzyme-linked immunosorbent assay (ELISA) on the first and second day of admission for each patient, in addition to completing APACHEⅡ score, medical history, vital signs collection and other biochemical indicators detection. Finally, paired-samples t test was used to analyze the data. The multiple ROC curve was used to calculate the area under the curve of the reference index of the serum levels of Ang-2 and CC16 on the first and second day. Results: On the first and second day, the serum levels of Ang-2 and CC16 were significantly higher in ARDS patients than those in non-ARDS patients, and there was a correlation between the serum levels of Ang-2 and CC16 in ARDS patients. The ROC curve showed that the combined detection of Ang-2 and CC16 on the first day achieved a highest sensitivity of 75.9% and detection of CC16 on the first day achieved a highest specificity of 70.2%. Conclusion Single-detection of serum levels of Ang-2 and CC16 could be used for early diagnosis of ARDS, and the combined detection of both has a higher sensitivity than single detection.

AIM: To explore the effect of pyrrolidine dithiocarbamate (PDTC), an NF-κB inhibitor, on the proliferation and apoptosis of human multiple myeloma U266 cells and its mechanisms.METHODS: The U266 cells were treated with PDTC at different concentrations (0, 25, 50, 100 and 200 μmol/L) in vitro.The growth inhibitory rate of the U266 cells was detected by CCK-8 assay and cell counting.The cell cycle of the U266 cells was determined by flow cyto-metry, and the apoptosis was examined by flow cytometry with Annexin V-FITC/PI staining.The effect of PDTC on the expression of DNA methyltransferase 1 (DNMT1) at mRNA and protein levels was measured by RT-qPCR and Western blot, respectively.The effects of PDTC on the protein levels of NF-κB (P65), DNMT1, Bcl-2, cyclin D1, cleaved caspase-3 and cleaved caspase-8 were determined by Western blot.RESULTS: The protein level of NF-κB (P65) was decreased after treatment with PDTC for 48 h or 72 h.PDTC inhibited the proliferation of U266 cells in both dose-and time-dependent manners.After treatment with PDTC for 48 h, the percentage of U266 cells in G2 phase increased compared with control group (P<0.05).PDTC induced the apoptosis of U266 cells in a dose-dependent manner.The expression of DNMT1 at mRNA and protein levels decreased (P<0.05).The results of Western blot showed that the expression of Bcl-2 in PDTC groups decreased, while the protein levels of cyclin D1, cleaved caspase-3 and cleaved caspase-8 were higher than those in control group (P<0.05).CONCLUSION: The NF-κB inhibitor PDTC inhibits the proliferation of U266 cells by inducing cell apoptosis.It may be related to the down-regulated expression of DNMT1, cell cycle arrest and activation of the apoptotic pathways.

Aim To study proliferation capacity of cell and the target relationship between microRNA and Runx2 after effect of puerarin on osteoblasts MC3 T3-E1 . Methods The proliferation capacity of cell was detected by MTT after effect of puerarin on osteoblasts MC3 T3-E1 . The vitality of osteoblasts was detected by activity of alkaline phosphatase. The expression level of mRNA and protein of Runx2 were detected by real-time quantitative PCR and Western blot. The result of miRNA expression spectrum was compared with the predicted result to determine the Runx2-targeting miR-NAs. The expression levels of miRNAs possiby targeted to Runx2 were detected by real-time quantitative PCR. The RhoE 3′UTR vector and RhoE mut 3′UTR vector were constructed. miRNA-204 mimics and miRNA-204 NC were synthetised. The target genes were verified by dual luciferase report gene assay. Results After osteo-blasts treated with puerarin, proliferation capacity and activity of cells were enhanced , expression levels of mRNA and protein of Runx2 were both increased , the expression levels of miRNA-204 and miRNA-344 f-5 p were declined, the expression levels of miRNA-2861 was increased,the expression levels of miRNA-23a-5p, miRNA-770-5 p and miRNA-871-5 p showed no obvious change. According to the results of dual luciferase re-porter gene method after cell transfection of 48 h, only set of 3′UTR Runx2+mimics the miRNA-204 of fluo-rescein protein expression level decreased significantly, showing only the miRNA-204 inhibits Runx2 3′UTR report gene expression. Conclusion Puerarin pro-motes the proliferation of osteoblasts and regulates the miRNAs which possibly target to Runx2 .

Objective To explore the correlative factors of sudden death in patients suspected with pulmonary thromboembolism (PTE) in emergency room (ER).Methods A retrospective analysis was conducted.The clinical data of 12 patients with sudden death suspected with PTE (sudden death group) in ER of the Air Force General Hospital from January 2011 to June 2014 were analyzed.The non-sudden death group included 35 patients during the same time period who were diagnosed with PTE based on findings of CT pulmonary arteriography (CTPA) and showed no sudden death in ER.Factors,including sex,age,previous operation,tumor,syncope,dyspnea,bilateral or unilateral edema of lower extremity,heart rate (HR),white blood cell count (WBC),D-dimer,arterial partial pressure of oxygen (PaO2),arterial partial pressure of carbon dioxide (PaCO2) and typical clinical manifestation of electrocardiogram (SⅠTⅢQⅢ),were compared between the two groups.The potential predictors of sudden death of PTE were analyzed by logistic regression analysis.Results Young age (years old:51.3±15.5 vs.62.3±14.4),lower PaO2 [mmHg (1 mmHg =0.133 kPa):49.9± 12.3 vs.62.7± 10.2],higher HR (bpm:122.0± 19.5 vs.89.1 ± 18.5) and higher WBC (× 109/L:13.8 ± 6.9 vs.7.2 ± 2.5) were found in sudden death group as compared with those in non-sudden death group (P ＜ 0.05 or P ＜ 0.01).There was no significant differences in D-dimer level and PaCO2 between sudden death group and non-sudden death group [D-dimer (pg/L):986 (891,3 230) vs.2089 (598,3 397),PaCO2 (mmHg):33.0 (28.6,43.4)vs.36.5 (32.9,41.0),both P ＞ 0.05].The syncope,antineoplaston treatment or tumor metastasis within 6 months,operation in previous 4 months,bilateral asymmetrical edema in sudden death group were more than those of the non-sudden death group,and chest pain was less (P ＜ 0.05 or P ＜ 0.01).Difference in gender,dyspnea and typical SⅠTⅢQⅢ in electrocardiogram were not significant between the two groups (all P ＞ 0.05).It was shown by multiple logistic regression analysis that higher HR [odds ratio (OR) =1.124,95％ confidence interval (95％CI) =1.024-1.235,P =0.014] and higher WBC (OR =1.347,95％CI =1.043-1.738,P =0.022) were identified as independent risk factors of sudden death for PTE.Conclusions Gender,dyspnea,typical S Ⅰ TⅢQⅢ in electrocardiogram,PaCO2 and D-dimer seem unrelated to sudden death of patients with PTE.Young age,chest pain,syncope,bilateral asymmetrical edema,antineoplaston treatment or tumor metastasis within 6 months,operation in previous 4 months and low PaO2 were potential predictors of sudden death according to the univariate analysis.Higher WBC and higher HR are independent risk factors of sudden death for PTE patients.
