OBJECTIVE: To assess the efficacy of Qingda Granule (QDG) in ameliorating hypertension-induced cardiac damage and investigate the underlying mechanisms involved. METHODS: Twenty spontaneously hypertensive rats (SHRs) were used to develope a hypertension-induced cardiac damage model. Another 10 Wistar Kyoto (WKY) rats were used as normotension group. Rats were administrated intragastrically QDG [0.9 g/(kg•d)] or an equivalent volume of pure water for 8 weeks. Blood pressure, histopathological changes, cardiac function, levels of oxidative stress and inflammatory response markers were measured. Furthermore, to gain insights into the potential mechanisms underlying the protective effects of QDG against hypertension-induced cardiac injury, a network pharmacology study was conducted. Predicted results were validated by Western blot, radioimmunoassay immunohistochemistry and quantitative polymerase chain reaction, respectively. RESULTS: The administration of QDG resulted in a significant decrease in blood pressure levels in SHRs (P<0.01). Histological examinations, including hematoxylin-eosin staining and Masson trichrome staining revealed that QDG effectively attenuated hypertension-induced cardiac damage. Furthermore, echocardiography demonstrated that QDG improved hypertension-associated cardiac dysfunction. Enzyme-linked immunosorbent assay and colorimetric method indicated that QDG significantly reduced oxidative stress and inflammatory response levels in both myocardial tissue and serum (P<0.01). CONCLUSIONS Both network pharmacology and experimental investigations confirmed that QDG exerted its beneficial effects in decreasing hypertension-induced cardiac damage by regulating the angiotensin converting enzyme (ACE)/angiotensin II (Ang II)/Ang II receptor type 1 axis and ACE/Ang II/Ang II receptor type 2 axis.

Objective:To compare the efficacy of active warming versus conventional warming during the perioperative period of robotic-assisted total hip arthroplasty (THA) for femoral neck fracture in elderly patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 312 elderly patients with femoral neck fracture who underwent robot-assisted THA at Second Affiliated Hospital of Xi ′an Jiaotong University from January 2024 to January 2025, including 196 males and 116 females, aged 65-89 years [(77.0±7.3)years]. Among them, 156 patients received standardized thermal management (active warming group), involving the administration of pre-warmed intravenous fluids and use of an inflatable warming blanket preoperatively, combined application of a forced-air warming system and warmed fluids intraoperatively, and transfer to a temperature-controlled ward combined with a foot circulatory compression device postoperatively. The other 156 patients received conventional warming with cotton quilts (conventional warming group), involving no administration of pre-warmed intravenous fluids preoperatively, use of warmed fluids intraoperatively, and transfer to a standard ward without the use of a foot circulatory compression device postoperatively. Core body temperature was compared between the two groups at 30 minutes preoperatively, 30 minutes intraoperatively, immediately postoperatively, and at 1 hour, 1 day, 5 days, and 7 days postoperatively. Changes in the coagulation function, including prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT), and the inflammatory marker C-reactive protein (CRP) were assessed at 1 day preoperatively and at 1, 5, and 7 days postoperatively. Length of hospital stay and incidence of postoperative complications (incision infection, deep vein thrombosis, cardiac complications, and unplanned reoperations) were also recorded. Results:The core body temperature at 30 minutes intraoperatively, immediately postoperatively and at 1 hour postoperatively was (36.77±0.17)℃, (36.29±0.14)℃, and (36.35±0.14)℃ in the active warming group, significantly higher than (36.12±0.27)℃, (35.49±0.25)℃, and (35.67±0.29)℃ in the conventional warming group ( P<0.01). No significant differences in body temperature were observed between the two groups at 30 minutes preoperatively, at 1, 5, or 7 days postoperatively ( P>0.05). At 1 day postoperatively, the PT, TT and APTT were (8.5±1.3)seconds, (10.0±0.9)seconds and (24.8±2.3)seconds, significantly lower than (9.7±1.3)seconds, (12.1±1.5)seconds and (29.2±2.7)seconds in the conventional warming group ( P<0.01). There were no significant differences in PT, TT, APTT or CRP levels between the two groups at 1 day preoperatively or at 5 and 7 days postoperatively ( P>0.05). The CRP level at 1 day postoperatively was (8.0±3.0)mg/L in the active warming group, significantly lower than (13.5±3.2)mg/L in the conventional warming group ( P<0.05). There were no significant differences in CRP between the two groups at 1 day preoperatively or at 5 and 7 days postoperatively ( P>0.05). The average length of hospital stay was (12.2±1.4)days in the active warming group, significantly shorter than (14.9±1.4)days in the conventional warming group ( P<0.01). The perioperative complication rate was 6.4% (10/156) in the active warming group, significantly lower than 17.9% (28/156) in the conventional warming group ( P<0.01). Conclusion:For elderly patients with femoral neck fracture operated via robot-assisted THA, active warming during the perioperative period can more effectively maintain intraoperative normothermia, improve early postoperative coagulation function, reduce inflammatory response, shorten the length of hospital stay, and decrease complication rate when compared with conventional warming.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

Objective: To compare the sensitivity of 8-color panels and next generation flow cytometry (NGF) for detecting minimal residual disease of multiple myeloma patients. Methods: 8-color-membrane antigens (8C-Mem) panel was built including CD45, CD38, CD138, CD19, CD56, CD81, CD27 and CD117 to identify the plasma cells, while 8-color-cytoplasmic antigens (8C-Cyto) panel was built including CD45, CD38, CD138, CD19, CD56, CD81, cKappa (cK) and cLambda (cλ) , and 8-color-two-tubes (8C-2tubes) panel were built including 8C-Mem and 8C-Cyto panels, the data of three groups was analyzed by Diva software. NGF uses Infinicyt software to fuse 8C-2tubes data to further analyze the expression of plasma antigens. Bone marrow aspiration obtained from 20 controls and 76 multiple myeloma patients who achieved complete remission were measured and analyzed. Results: Positive MRD samples were discriminated in 88.2% of the specimen evaluated through either abnormal plasma cells (aPCs) or clonal plasma cells (cPCs) by NGF antigens panel, Among of them, consistency was 94.7%. The median percentage of cPCs was 0.3530%, The lowest sensitivity of NGF was 0.0003%. In 8-color panels, the positive MRD rates of 8C-Mem, 8C-Cyto and 8C-2tubes panels were 84.2%, 85.5% and 86.8%, respectively, which lower than that of NGF (P<0.001) . The positive MRD rate of 8C-Mem and 8C-Cyto panels were lower than that of 8C-2tubes panel (P<0.001) , and the positive MRD rate of 8C-Mem panel was lower than that of 8C-Cyto panel (P<0.001) . Sensitivity and specificity of NGF was higher than that of 8-color panels. 8C-2tubes panel has the best sensitivity, accuracy, negative predicted value, positive predicted value and specificity than other 8-color panels. However, huge data and low efficiency for analysis is the disadvantage. 8C-Cyto panel was the second choice, and 8C-Mem panel was the last. Conclusions: Membrane and cytoplasmic light chain is a better method for multiple myeloma-MRD detection and NGF panel is an ideal approach. 8C-Cyto panel is recommended in 8-MFC groups.

BACKGROUND: Investigation on epidemiologic features of knee osteoarthritis in many areas of China has been much reported. However, multicenter studies with large samples have been rarely reported. The published papers cannot give a good description about the epidemiologic features of knee osteoarthritis. OBJECTIVE: To evaluate the epidemiologic features of knee osteoarthritis in the patients aged over 40 years in China. METHODS: Meta-analysis was used to evaluate the data extracted from papers published 2001-2016 on the epidemiology of knee osteoarthritis in the middle-aged and elderly in China. The prevalence rate of knee osteoarthritis in the patients over 40 years of age was summarized, with every 10 years as group, and then analyzed on Stata 12.0 software. RESULTS AND CONCLUSION: Twenty-six articles were included, involving 42 199 people aged more than 40 years old. The total prevalence rate of knee osteoarthritis at the age above 40 years old in China was 17.0% (95% CI:16.7%-17.4%),the prevalence rate was 12.3% in male and 22.2% in female(P<0.05).Noticeably,the prevalence rate increased with age.The total prevalence rate in northern China was 16.1%(95% CI:15.6%-16.6%),12.2% in male and 21.4% in female;the total prevalence in southern China was 18.0%(95%CI:17.5%-18.5%), 12.3% in male and 23.1% in female. There was no significant difference in the prevalence rate between northern and southern China(P>0.05).The total prevalence rate in rural China was 23.6%(95%CI:16.7%-30.4%),with 15.4% in male and 28.1% in female;and the total prevalence in urban China was 20.0%(95% CI:16.2%-23.9%),with 13.7% in male and 24.3% in female. There was no significant difference in the prevalence rate between rural and urban China (P > 0.05). These results suggest that knee osteoarthritis in China is a common disease, characterized by increased prevalence with age, relatively significant difference between male and female, but no difference between northern and southern China as well as between rural and urban China. It is of great significance to timely propagate and perform interventional strategies for prevention and treatment of knee osteoarthritis in China.

Objective To predict the antiviral and anti-inflammatory mechanisms of major compounds from the flowers of Trollius chinensis, namely, vitexin, orientin, 2"-O-β-L-galactopyranosylvitexin, 2"-O-β-L-galactopyranosylorientin, veratric acid, and trolline, by using the molecular docking technique. Methods Discovery Studio 2.5 software and Chinese Medicine Chemistry Database were employed for docking between the ligands including 6 compounds and the proteins including Toll-like receptors (TLRs) and neuraminidase (NA). The docking results and interactions of their functional domains were obtained by simulation analysis. Results Vitexin, orientin, 2"-O-β-L-galactopyranosylvitexin, veratric acid, and trolline were applied to one or more TLR, whereas 2"-O-β-L-galactopyranosylorientin could interact with neither of the proteins investigated. Flavonoids, namely vitexin, orientin, 2"-O-β-L-galactopyranosylvitexin and 2"-O-β-L-galactopyranosylorientin were applied to NA, whereas veratric acid and trolline could not interact with NA. Conclusion Five out of the 6 compounds have influence on the signaling pathways mediated by TLRs, and TLR3, 4, and 7 are their potential targets for antivirus and anti-inflammation. Four flavonoids can affect the activity of influenza virus by interacting with NA. This study can provide a basis for the investigation of the antiviral and anti-inflammatory effective compounds of the flowers of Trollius chinensis and the further development.

Background: Automated peritoneal dialysis (APD) can cater to individual needs, provide treatment while asleep, take into account the adequacy of dialysis, and improve the quality of life. Currently, independent research and development of APD machines made in China are more conducive to patients. A randomized, multicenter, crossover study was conducted by comparing an APD machine made in China with an imported machine. The safety, effectiveness, and manipulability of the two machines were compared. Methods: Two hundred and sixty patients who underwent peritoneal dialysis (PD) on a regular basis in 18 centers between August 2015 and February 2016 were included. The inclusion criteria include age ≥18 years and PD ≥30 days. The exclusion criteria were as follows: hemodialysis; exit site or tunnel infection; and peritonitis ≤30 days. The patients were randomly divided into Group A, who were first treated with a FM machine made in China, then changed to an imported machine; and Group B, who were treated using the reverse sequence. APD treatment was performed with 10 L/10 h and 5 cycles of exchange. After 72 h, the daily peritoneal Kt/V, the accuracy of the injection rate, accuracy of the injection temperature, safety, and manipulability of the machine were assessed. Noninferiority test was conducted between the two groups. Results: The daily peritoneal Kt/V in the APD machine made in China and the imported APD machine were 0.17 (0.14, 0.25) and 0.16 (0.13, 0.23), respectively. There was no significant difference between the groups (Z = 0.15, P = 0.703). The lower limit of the daily Kt/V difference between the two groups was 0.0069, which was greater than the noninferiority value of -0.07 in this study. The accuracy of the injection rate and injection temperature was 89.7% and 91.5%, respectively, in the domestic APD machine, which were both slightly better than the accuracy rates of 84.0% and 86.8% in the imported APD machine (89.7% vs. 84.0%, P = 0.2466; 91.5% vs. 86.8%, P = 0.0954). Therefore, the APD machine made in China was not inferior to the imported APD machine. The fuselage of the imported APD machine was space-saving, while the APD machine made in China was superior with respect to body mobility, man-machine dialog operation, alarm control, and patient information recognition. Conclusions: The FM machine made in China was not inferior to the imported APD machine. In addition, the FM machine made in China had better operability.
