Background and purpose:Urothelial carcinoma of the bladder (UCB) is the most common cancer in urinary system. Yes associated protein (YAP) gene is closely associated with urothelial carcinoma of the bladder. The study was aimed to explore the effect of siRNA targeting the YAP gene on cell proliferation and migration of T24 cells. Methods:Small interfering RNA (siRNA) was transfected together with LipofectamineTM2000 in T24 human bladder cancer cells to block the YAP signal pathway. The effect of siRNA on cell proliferation and invasiveness was assessed by cell counting kit-8 (CCK-8) assay, Transwell migration assay and wound healing assay. Quantitative real time-Polymerase chain reaction (qRT-PCR) and Western blot analysis were used to conifrm the successful suppression of YAP gene and protein by siRNA. Results:Expression of YAP gene and protein was successfully suppressed after transfected with siRNA which verified by qRT-PCR and Western blot(RNA:F=93.91, P<0.000 1; Protein: F=4.62, P<0.05). As CCK-8 test showed, the proliferation of T24 bladder cancer cells was successfully restrained by inhibition of YAP gene compared with blank control and negative control(12 h: F=6.00, P=0.037;24 h: F=41.72, P=0.000 3;36 h:F=462.8, P<0.000 1;48 h:F=236.6, P<0.000 1;72 h:F=140.5, P<0.000 1). Transwell and wound healing test were performed after YAP gene was interfered by siRNA. The result demonstrated that migration of T24 bladder cancer cells was signiifcantly inhibited (Transwell: F=43.55, P<0.05;Wound healing: F=43.55, P<0.05). Conclusion:This study suggested that YAP gene was an important enhancer for the proliferation and migration of bladder cancer cells.

Objective:To investigate the clinical efficacy of thunder-fire moxibustion combined with external application of Chinese herbal ointment at the trigger point on lumbodorsal myofascial pain syndrome of cold-damp stagnation type.Methods:A total of 90 patients with lumbodorsal myofascial pain syndrome of cold-damp stagnation type admitted to Zhejiang Provincial Hospital of Integrated Traditional Chinese and Western Medicine from September 2021 to April 2022 were included in this study. They were randomly divided into three groups ( n = 30/group) using the random number table method. Patients in the Chinese herbal ointment group were treated by external application of Chinese herbal ointment at the trigger point. Patients in the thunder-fire moxibustion group were treated with thunder-fire moxibustion. Patients in the combined therapy group were treated with thunder-fire moxibustion combined with external application of Chinese herbal ointment at the trigger point. All patients were treated for 28 consecutive days. Clinical efficacy was compared among the three groups. Before and after treatment, the Visual Analogue Scale score, local tenderness score, Oswestry Disability Index score and Pittsburgh Sleep Quality Index score were compared among the three groups. Results:Total response rate (96.67%) in the combined therapy group was significantly higher than 73.33% in the thunder-fire moxibustion group and 66.67% in the Chinese herbal ointment group ( χ2 = 9.01, 4.70, both P < 0.05). Visual Analogue Scale score and local tenderness score in the combined therapy group were (1.96 ± 0.93) points and (1.00 ± 0.69) points, respectively, which were significantly lower than (2.43 ± 0.87) points and (1.37 ± 0.56) points in the thunder-fire moxibustion group and (2.77 ± 0.86) points and (1.50 ± 0.57) points in the Chinese herbal ointment group ( F = 6.22, 5.38, both P < 0.05). The Oswestry Disability Index score in the combined therapy group was (19.80 ± 3.80) points, which was significantly lower than (22.30 ± 2.82) points in the thunder-fire moxibustion group and (23.60 ± 3.71) points in the Chinese herbal ointment group ( F = 9.07, both P < 0.05). After treatment, the Pittsburgh Sleep Quality Index score in the combined therapy group was (5.30 ± 1.12) points, which was significantly lower than (6.50 ± 1.33) points in the thunder-fire moxibustion group and (6.73 ± 1.41) points in the Chinese herbal ointment group ( F = 10.59, both P < 0.05). Conclusion:Thunder-fire moxibustion combined with external application of Chinese herbal ointment at the trigger point is highly effective on lumbodorsal myofascial pain syndrome of cold-damp stagnation type than monotherapy. The combined therapy can markedly reduce pain and greatly improve lumbodorsal function and sleep quality.

The present study analyzed and identified the chemical constituents from ethyl acetate(EA) extract of Taxilli Herba with UPLC-Q-Exactive-MS and screened active xanthine oxidase(XO) inhibitors with HPLC. The analysis was performed on an Hypersil GOLD C_(18) reversed-phase column(2.1 mm×50 mm, 1.9 μm), with the mobile phase of water containing 1% formic acid(A) and methanol(B) under gradient elution, the flow rate of 0.3 mL·min~(-1), and the injection volume of 5 μL. ESI source was used for MS and the compounds were collected in positive and negative ion modes. Xcalibur 4.1 was used to analyze the retention time, accurate relative molecular weight, and fragmentation of the compounds. The inhibitory activity of some known compounds on XO was screened by HPLC. Thirty chemical constituents were identified, including phenolic acids and flavonoids by experimental data combined with information of standards, data reported previously, and databases, such as MzCloud and ChemSpider. The activities of 10 chemical components were screened. Gallic acid and naringenin chalcone had strong inhibitory activities on XO with IC_(50) of 57 μg·mL~(-1) and 108 μg·mL~(-1). UPLC-Q-Exactive-MS allows the accurate, rapid, and comprehensive identification of main chemical constituents from Taxilli Herba. Gallic acid and naringenin chalcone may be the active components of XO inhibitors.

OBJECTIVETo explore the relationship between fasting C-peptide (F-CP) and serum uric acid (SUA) in patients with type 2 diabetes mellitus (T2DM).

METHODSA total of 347 hospitalized patients with T2DM were stratified according to F-CP level to analyze the impact of increased F-CP levels on SUA level and the incidence of hyperuricemia (HUA). The patients with an elevated SUA level (>420 µmol/L) and a normal SUA level (≤420 µmol/L) were compared for general data, fasting C-peptide and other clinical indexes. Pearson or Spearman correlation analysis was used to analyze the correlation of SUA level with F-CP levels and other parameters. The risk factors of elevated SUA were analyzed by binary logistic regression, multiple regression analysis and hierarchical interaction analysis. The ROC curve was used to analyze the independent risk factors of elevated SUA and determine the corresponding cut-off values.

RESULTSCompared with those with a normal SUA level, patients with elevated SUA had higher body mass index (BMI), waist-to-hip ratio, F-CP, postprandial 2hC peptide (2hP-CP), triglyceride (TG), homocysteine (HCY), serum creatinine (SCr) level (P<0.05), and a greater percentage of drinking (44.8% vs 32.6%, P=0.006), but had significantly lowered levels of HbA1c, high-density lipoprotein (HDL), and estimated glomerular filtration rate (eGFR) (P<0.05). SUA was found to be positively correlated with F-CP, 2hP-CP, BMI, waist-to-hip ratio, diastolic blood pressure, TG, HCY, SCr, smoking and drinking (P<0.05), and was negatively correlated with gender, age, age of disease onset, HbA1c, HDL and eGFR (P<0.05). SUA level and the incidence of hyperuricemia increasea significantly with F-CP level (P<0.05). F-CP was identified as an independent risk factor for elevated SUA, and gender did not affect the relationship between F-CP and SUA. ROC curve analysis showed that a F-CP level >1.260 ng/mL was associated with a significantly increased risk of hyperuricemia in T2DM patients.

CONCLUSIONF-CP is closely related with SUA and may be an independent risk factor of elevated SUA in patients with T2DM.

Objective To investigate the regulating effect and mechanism of microRNA-21 (miR-21) on extracellular matrix (ECM) of vascular smooth muscle cells (VSMCs) by vascular remodeling of hypertension. Methods By narrowing the abdominal aorta in rats, the hypertension models were established and divided into 2-week hypertension group and 4-week hypertension group, and sham-operated group was also established as control. VSMCs from the rat aorta were subjected to 0% (static), 5% (normal) and 15%（hypertensive）elongation strain at a constant frequency of 1.25 Hz and duration of 12 hours, respectively. The expressions of Smad 7 and ECM were detected by Western blotting, and the expression of miR-21 was examined by Real-time RT-PCR. Finally, miR-21 siRNA was used to study the role of miR-21 in the mechanical strain-induced expression of ECM, miR-21 and Smad 7. Results Compared with the sham-operated group, ECM and miR-21 in thoracic aorta of 2-week hypertension group were significantly elevated. Collagen I, collagen III and miR-21 in thoracic aorta of 4-week hypertension group were significantly elevated. Compared with the static and 5% strain groups, the protein expression of collagen I in VSMCs did not show significant change, but the protein expression of collagen III was significantly elevated and Smad 7 expression was significantly decreased in 15% strain group. The cyclic strain also enhanced miR-21 expression in VSMCs. miR-21 inhibitor effectively decreased the expression of miR-21 in VSMCs and protein level of collagen III, while enhanced Smad 7 expression under the static and 15% strain. Conclusions The vascular remodeling of hypertension causes the high expressions of ECM and miR-21. The cyclic strain induces the high expression of miR-21, which via Smad 7 results in enhancing the expression of ECM, collagen III especially, in VSMCs under vascular remodeling of hypertension.

To evaluate the efficacy and safety of Compound Glycyrrhizin Injection(CGI) in improving liver damage in chronic hepatitis B(CHB). PubMed, Web of Science, SinoMed, CNKI, Wanfang and VIP databases were retrieved from their inception to February 10, 2020. The randomized controlled trial(RCT) of CGI in the treatment of CHB was included. Data were independently extracted by two authors, and the methodological quality was evaluated using the Cochrane bias risk assessment tool by other two authors. Statistical analysis was performed using RevMan 5.3 software. A total of 18 two-armed RCTs were included, involving 1 915 participants. The methodological quality of all studies included was generally low. In the comparison between CGI and diammonium glycyrrhizinate, the results showed that CGI was superior to the control group in improving the overall clinical effectiveness, but there was no statistical difference between the two groups in increasing ALT normalization rate, reducing ALT and AST level. In the comparison between CGI and diammonium glycyrrhizinate+other general hepatoprotective drugs, the results showed that CGI was superior to the control group in reducing AST level, while there was no statistical difference between the two groups in reducing ALT level and increasing overall clinical effectiveness. In the comparison between CGI+other commonly used drugs(including energy mixture, glutathione, vitamins, potassium magnesium aspartate) and diammonium glycyrrhizinate+other commonly used drugs, the results showed that CGI combined with other commonly used drugs was better than the control group in reducing ALT and AST level and improving the clinical total effective rate, and there was no statistical difference between the two groups in increasing the rate of ALT normalization. In the comparison between CGI+other commonly used drugs and other commonly used drugs, the results showed that CGI combined with other commonly used drugs was superior to the control group in reducing ALT and AST level and improving the overall clinical effectiveness. In the comparison between CGI+vitamins and diammonium glycyrrhizinate+potassium magnesium aspartate+vitamins, the results showed no statistical difference between the two groups in reducing AST level. A small number of studies included reported that CGI caused mild adverse reactions when used alone or in combination with other drugs. Based on the results, CGI has a certain effect in improving CHB liver damage, but the evidence is not enough to prove that CGI would cause serious adverse events. In the future, more well-designed and strictly-enforced RCT with an adequate sample size are needed to further evaluate the effect CGI in alleviating CHB liver damage.
