Objective Reliability and validity of the Chinese version of disability attitude scales(DAS-CN)toward disabled persons were created and tested to provide an assessment instrument for measuring the attitude of medical staff toward disabled persons in China.Methods Authorised by the author of DAS in August 2020,based on BRISLIN translation model,the English version of DAS was translated into Chinese followed by back translation,cultural debugging and then put it into pre-experiment in September 2020.The reliability and validity of the finalised DAS-CN were further tested in a survey with 400 randomly selected medical staff in rehabilitation from 8 general hospitals in Jinzhou,Panjin,Yingkou and Fushun in Liaoning Province,China by using the convenience sampling method in March 2021.Results A total of 357 surveyees completed the survey.The localised DSA-CN was composed of 4 dimensions with a total of 20 items,including 4 items in clinical knowledge and skills,4 in clinical responsibility,8 in clinical behaviour and 4 in emotional response.The Cronbach α coefficient of the scales was 0.943,with the split-half reliability and test-retest reliability at 0.824 and 0.899,respectively.The Cronbach α coefficient of each dimension was 0.843～0.944,and the split half reliability was 0.854～0.904.The test-retest reliability ranged from 0.701 to 0.913.The KMO value of exploratory factor analysis was 0.921.The Bartrett spherical test value was 5534.981(P<0.01).The total explanatory rate of variation was 73.050%.Conclusion The Chinese version of Disability Attitude Scales(DSA-CN)has good reliability and validity.Therefore,DSA-CN can be used as an instrument in investigation of the current status about the attitudes towards the disabled persons among the medical staff in China.

Renal fibrosis， the final pathological outcome of end-stage chronic kidney diseases， is associated with inflammation， oxidative stress， epithelial-mesenchymal transdifferentiation （EMT）， and extracellular matrix deposition. It belongs to the categories of edema， ischuria， anuria and vomiting， and consumptive disease in traditional Chinese medicine （TCM）， with the key pathogenesis of Qi deficiency and blood stasis and the primary treatment principle of replenishing Qi and activating blood. Astragali Radix-Salviae Miltiorrhizae Radix et Rhizoma mainly contains astragalosides， polysaccharides， calycosin， salvianolic acid， and tanshinone， with the effect of tonifying Qi and activating blood. Studies have shown that this herb pair and its active components can delay the progress of renal fibrosis by regulating multiple signaling pathways. With consideration to the pathogenesis of Qi deficiency and blood stasis， this article reviews the research progress in the mitigation of renal fibrosis by Astragali Radix-Salviae Miltiorrhizae Radix et Rhizoma from the aspects of protecting glomerular filtration barrier， inhibiting EMT and mesangial cell proliferation， improving renal hemodynamics， and protecting renal function. Furthermore， the mechanisms were summarized. Specifically， Astragali Radix-Salviae Miltiorrhizae Radix et Rhizoma and its effective components can improve mitochondrial function and fatty acid metabolism， alleviate endoplasmic reticulum stress and autophagy disorders， and inhibit immune inflammation and oxidative stress by regulating nuclear factor E₂-related factor 2 （Nrf2）/PTEN-induced kinase 1 （Pink1）， Nrf2/antioxidant response element （ARE）， tumor necrosis factor-α （TNF-α）/nuclear transcription factor-κB （NF-κB）， miR-21/Smad7/transforming growth factor beta （TGF-β）， Wnt/β-catenin， long non-coding RNA-taurine up-regulated gene 1 （lncRNA-TUG1）/tumor necrosis factor receptor-associated factor 5 （TRAF5）， Ras-related C3 botulinum toxin substrate 1 （Rac1）/cell division cycle protein 42 （CDC42）， Ras homolog （Rho）/Rho-associated coiled-coil containing protein kinase （ROCK）， phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， peroxisome proliferator-activated receptor α （PPARα）/peroxisome proliferator-activated receptor γ coactivator l alpha （PGC-1α）， and p38 mitogen-activated protein kinase （p38 MAPK）. This review aims to provide references for the relevant research， give play to the role of Astragali Radix-Salviae Miltiorrhizae Radix et Rhizoma， and provide guidance for the clinical treatment of renal fibrosis.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

This study is a randomized controlled trial of Reyanning Mixture in the treatment of acute tonsillitis. According to the ratio of 1∶1∶1, a total of 144 patients were randomly divided into Reyanning Mixture group(RYN), Reyanning Mixture+Amoxicillin Capsules group(RYN+Amoxil) and Amoxicillin Capsules group(Amoxil), with 48 cases in each group, in order to evaluate the efficacy and safety of RYN alone or combined with Amoxil in the treatment of acute tonsillitis, and provided high-quality evidences for treatment of infectious diseases with traditional Chinese medicine and reduced use of antibiotics. The dosage of RYN was 20 mL, 3 times a day, 100 mL/bottle, oral for 7 days, and Amoxil dosage was 0.5 g, 3 times a day, 0.5 g×12 tablets/plate, oral for 7 days. A total of 144 cases were included, 3 cases were excluded(1 case was mistakenly included, 2 cases did not take drugs after inclu-ded), and a total of 141 cases were included in the full analysis set(FAS). The results showed statistical differences in the recovery time of the disease, the disappearance rate of fever on the 3 rd day and the disappearance rate of tonsillar redness and swelling between RYN and Amoxil. There were statistical differences in the cure rate of disease, recovery time of disease, body temperature recovery time, fever disappearance rate on the 3 rd day, pharynx swelling and pain disappearance rate and tonsil swelling disappearance rate between the RYN+Amoxil and Amoxil, but with no significant difference in the above aspects compared with RYN. The DDD of antibiotic use in RYN+Amoxil was significantly lower than that in Amoxil(P<0.01). According to the findings, when RYN was used alone in the treatment of acute tonsillitis, it was superior to Amoxil in time of recovery, short-term improvement of fever and redness and swelling of tonsil. Compared with RYN+Amoxil, there was no difference in cure rate of disease, recovery time of disease, body temperature recovery time, short-term improvement of fever, swelling of pharynx and swelling of tonsil, with a better efficacy than Amoxil. The clinical effect of RYN was similar to that of combined Amoxil in the treatment of acute tonsillitis, and RYN was superior to Amoxil in the time of recovery, short-term improvement of fever and redness and swelling of tonsil, with no adverse event or adverse reaction. RYN+Amoxil can significantly reduce the DDD value of antibiotics in the treatment of acute tonsillitis, with significant clinical advantages over Amoxil.

OBJECTIVE: To observe the effects of electroacupuncture (EA) on reproductive outcomes in women with Shen (Kidndy) deficiency syndrome after in vitro fertilization-embryo transfer (IVF-ET), and explore the underlying molecular mechanism. METHODS: Sixty-six infertile patients with Shen deficiency syndrome undergoing IVF-ET were divided into EA or control groups according to a random table, 33 cases in each group. Before undergoing IVF, patients in the EA and control groups received EA therapy and placebo needle puncture, respectively, for 3 menstrual cycles. Shen deficiency syndrome scores were assessed. Other outcome measures included the number of retrieved oocytes and fertilization, high-quality embryo and clinical pregnancy rates. Follicular fluid was collected on the day of oocyte retrieval, and granulosa cell expression of phosphatidylinositide 3-kinases (PI3K), serine-threonine kinase (Akt) and forkhead box O3 (Foxo3a) mRNA were measured by reverse transcribed and quantitative real-time polymerase chain reaction. RESULTS: Syndrome scores for pre- versus post-treatments decreased significantly (16.53±1.75 to 8.67±1.61) in the EA group (P<0.05), but showed no significant change in the control group (17.18±1.58 to 14.74±1.58). A significant difference in score change was found between the EA and control groups (P<0.05). High-quality embryo and clinical pregnancy rates were both increased in the EA group compared with the control group [69.15% (195/282) vs. 60.27% (176/292) and 66.67% (22/33) vs. 42.42% (14/33), respectively, P<0.05]. The fertilization rate was equivalent in EA and control groups. No difference was found in the number of retrieved oocytes between the two groups. Granulosa cell expression levels of PI3K and Akt mRNA were significantly increased in the EA group compared with the control group, while the expression of Foxo3a was reduced (all P<0.05). CONCLUSIONS For infertile patients with Shen deficiency syndrome undergoing IVF, EA for tonifying Shen as an adjunct treatment may alleviate clinical symptoms and improve the high-quality embryo rate. The EA-induced mechanism may involve regulation of PI3K/Akt/Foxo3a expression in granulosa cells to improve the developmental microenvironment of oocytes and inhibit granulosa cell apoptosis, possibly contributing to the improved clinical pregnancy rate (Registration No. ChiCTR 1800016217).

Objectives: This study aimed to observe the change of arachidonic acid-induced platelet aggregation rate (AA-Ag) and short-term adverse reactions after taking 50 or 100 mg/d aspirin(enteric-coated sustained-release formulation) or 100 mg/d aspirin (enteric-coated aspirin tablet)in the elderly Chinese population (aged 60 years or older). Methods: A total of 1 194 participants aged 60 or older, who should be recommended to take aspirin therapy due to medical reasons, were recruited and randomly assigned into three groups to receive enteric-coated sustained-release aspirin tablet (50 mg, once daily, group A), or 100 mg, once daily (group B) or enteric-coated aspirin tablet 100 mg once daily (group C), respectively. AA-Ag was measured after (14±3)days of aspirin treatment. Adverse events and bleeding events were recorded during the (28±3)days of follow-up. Results: The AA-Ag in group A (n=347), B (n=338) and C (n=332) post 14-day aspirin therapy were 6.65 (4.03,10.84)%, 5.89(3.22,10.03) % and 6.00(3.68,10.09) %, respectively (P>0.05). During the 28 days follow-up, the adverse events rate of group A (n=388), B (n=387) and C (n=385) was 3.87%,3.36%, and 7.95%, and the mild bleeding events rate was 3.09%, 2.33%, and 6.23%, respectively. Adverse events rate and mild bleeding events rate were significantly higher in group C than in group A and B (P<0.05). Conclusions: Compared with 100 mg-dose aspirin, 50 mg-dose aspirin achieves similar anti-platelet aggregation effect in this elderly Chinese population. The short-term adverse events and mild bleeding risk of aspirin with enteric-coated sustained-release formulation were fewer than that of enteric-coated formulation.
