In traditional oral practice, the presystemic interactions with gut microbiota is an important mechanism underlying the holistic health benefits of Chinese herbal medicines (CHMs), making the study of CHMs distinct from the research of Western medicines of which the systemic exposure (level in blood) is the starting point and the core. Gut microbial metabolism complements host metabolism in maintaining metabolic homeostasis of many biologically important endogenous molecules and the disposition of numerous exogenous compounds. Among them, the widely distributed gut bacterial

Objective Heart transplantation is an effective treatment of end-stage heart diseases and extending the time of donor heart preservation helps to make up for the shortage of donor hearts. This study was to investigate whether high-pressured mixed gas ( HPMG) of carbon monoxide and oxygen could prolong the time of donor heart preservation and its mechanisms. Methods Forty-eight C57BL/6 male mice aged 4-6 weeks were randomly divided in-to four groups of equal number:control ( the donor heart isolated but not transplanted) , immediate transplantation ( the donor heart transplanted right after isolated) , HTK-preservation ( the donor heart preserved in histidine-tryptophan-ketoglutarate solution for 24 hours after isolated, and HPMG preservation ( the donor heart preserved in an HPMG chamber with the oxygen partial pressure of 3200 hPa and carbon monoxide partial pressure of 800 hPa for 24 hours after isolated) .Another 36 recipient mice aged 6-8 weeks were randomly assigned to receive the donor heart immediately after harvested (n=12), preserved in HTK solution (n=12), or preserved in HPMG (n=12).At 2 hours after transplantation, the status of heart re-beating and cardiac function were compared among different groups of recipient mice.At 24 hours, tissues were taken from the transplanted hearts for examination of pathologic changes by HE stai-ning, detection of the apoptosis of cardiac cells by TUNEL, and determination of the expressions of microtubule-associated protein 1 light chain 3 -Ⅱ(LC3-Ⅱ) and B cell lymphoma/leukemia-2 (Bcl-2) by Western blot. Resul ts The re-beating rates of the imme-diately transplanted and HPMG-preserved hearts were significantly higher than that of the HTK-preserved ones (P<0.05).At 2 hours after transplantation, the cardiac function scores were 2.5 (2.0-2.9), 0.8 (0.5-1.0), and 4.5 (4.0-4.5) in the immediate implantation, HPMG-preservation and HTK-preservation groups respectively, with statistically significant differences between any two groups (P<0.05).The expressions of LC3-Ⅱand Bcl-2 were 2.06 ±0.29 and 0.87 ±0.18 in the HPMG-preserved heart recipients and 1.24 ±0.20 and 2.07 ±0.32 in the immediately transplanted heart recipients, both higher than 0.13 ±0.03 and 0.19 ±0.02 in the controls and 0.16 ±0.06 and 0.26 ±0.08 in the HTK-preserved heart recipients (P<0.05), the Bcl-2 higher in the HTK-pre-served heart recipients than in the controls (P<0.05), and the LC3-Ⅱ expression higher in the HPMG-preserved heart recipients than in the immediately transplanted heart recipients (P<0.05).HE staining showed that cell edema and inflammatory cell infiltration were more obvious in the HPMG-preserved heart recipients than in the controls and immediately transplanted heart recipients but less obvious than in the HTK-preserved heart recipients.The rate of cell apoptosis was dramatically increased in the HPMG-and HTK-pre-served heart recipients ([5.04 ±1.77]%and [26.72 ±5.23]%) in comparison with the controls ([1.08 ±0.56]%) (P<0.01) and immediately transplanted heart recipients ([2.13 ±1.71]%) (P<0.01) but decreased in the HPMG as compared with the HTK-preserved heart recipients (P<0.01). Conclusion High-pressured mixed gas preservation can reduce cold ischemia-reperfu-sion injury of the donor heart, which may be associated with its promotion of autophagy, provision of energy to cells, and apoptosis of cardiocytes in the donor heart.

Objective:To survey the knowledge,attitude and practice (KAP) for diabetic retinopathy (DR) among diabetic patients in Shanghai suburb, and to analyze the related influencing factors.Methods:A cross-sectional survey on KAP for diabetic retinopathy was conducted from January to January 2022,a total of 260 diabetic patients were selected from Huacao Town of Shanghai Minhang District by stratified cluster random sampling method as the investigation subjects. The gender, age, height, weight, education level, occupation, frequency of exercise or outdoor sports, medical insurance status, comorbid chronic diseases, diabetic retinopathy in direct relatives were documented;the KAP of diabetes retinopathy prevention and treatment was investigated by a self-designed questionnaire. The influencing factors were analyzed by univariate and multivariate regression analysis.Results:A total of 260 valid questionnaires were received with a recovery rate of 100.0%. The survey showed that the knowledge awareness rate, attitude positive rate and behavior execution rate were 25.38% (66/260), 50.76% (132/260) and 14.61% (38/260), respectively; scores of knowledge,attitude,behavior and medication compliance of the subjects were 13.74±4.55, 10.40±3.23 and 14.92±4.51, respectively. Univariate analysis showed that the knowledge was significantly related to occupations,frequency of exercise or outdoor exercise,chronic disease, direct relatives with DR( F=5.03, 8.77, 5.08, 32.37,all P<0.05);the attitude was significantly related to age, education level, chronic disease, direct relatives with DR and awareness level of DR( F=2.12, 2.09, 2.75, 3.28,all P<0.05); the behavior was significantly related to age, frequency of exercise or outdoor exercise, direct relatives with DR( F=2.30, 2.70, 3.11,all P<0.05). Multiple stepwise linear regression analysis showed that the knowledge awareness score was significantly associated with age,education levels,direct relatives with DR( t=2.83, 2.46, 6.24,all P<0.05),and the age, chronic disease, awareness score were significantly associated with the attitude toward DR prevention and treatment ( t=3.70, 3.42, 6.03,all P<0.05).Patients with insufficient awareness had worse behavior of DR prevention and treatment( t=11.00, P<0.05). Conclusions:The KAP status of DR prevention and treatment in diabetes patients in Huacao Town is less satisfactory. In order to prevent the occurrence of diabetic retinopathy, it is necessary to strengthen health education, improve self-management ability, enhance lifestyle intervention, and increase the frequency of exercise or outdoor exercise in diabetic patients.

OBJECTIVE To make a comparison of sensitivity and specificity between serum miR-122 and traditional biomarkers of drug-induced liver injury. METHODS Acetaminophen (APAP, 1250 mg · kg-1, ig), α-naphthylisothiocyanate (ANIT, 150 mg · kg-1, ig), methionine-choline deficient diet (MCDD, free feeding) and carbon tetrachloride (CCl4, 50%, ip) were used to establish hepatocellular injury, cholestasis, steatosis and fibrosis models, respectively, which were used to evaluate the sensitivity of serum miR-122 as a biomarker of drug-induced liver injury, when compared with the traditional biomarkers. Isoprenaline hydrochloride (IH) and gentamicin (GM) were used to establish myocardial and renal injury models, respectively, which were used to evaluate the specificity of serum miR-122, when compared with the tradi-tional biomarkers. Serum and liver tissues were collected at different time points during the study. Tradi-tional biomarkers such as glutamic-pyruvic transaminase (GPT), glutamic-oxaloacetic transaminase (GOT) and total bilirubin (TBIL) were measured with an automatic biochemistry analyzer. MiR-122 was detected with real- time quantitative PCR. Histopathological examination with HE staining was performed for liver tissues. RESULTS Serum miR-122 increased significantly earlier [miR-122 was signifi-cantly increased (>2 fold) at 1.5 h, 3 h, 2 weeks and 4 weeks after treatment in the four models respec-tively, while no significant increase (<2 fold) was observed for GPT, GOT and TBIL at 6 h, 12 h, 3 weeks and 6 weeks after treatment in the four models respectively] and more signficantly (the maximum fold change for miR-122 was 235.8, 202.7, 73.8 and 600.3 for the four models, respectively. For the GPT, the maximum fold change was 9.5, 3.9, 2.5 and 6.6, respectively; 6.0, 2.4, 1.4 and 3.5 respectively for GOT; 2.6, 2.3, 1.2 and 1.8 respectively for TBIL) than that of traditional biomarkers in hepatocellular injury, cholestasis, steatosis and fibrosis models, when compared with the control group. In the myocar-dial injury model, a significant increase of GOT was observed after IH treatment (2.1 fold), while no change was observed for serum miR-122. In the renal injury model, no false positive results were observed for serum miR-122. CONCLUSION Serum miR-122 can be used as a biomarker of drug-induced liver injury and serum miR-122 is more sensitive and specific than traditional biomarkers (such as GPT, GOT and TBIL).

OBJECTIVE:
To establish a screening model for females of reproductive age carrying Duchenne muscular dystrophy (DMD) variants based on a current community health examination platform.
METHODS:
A total of 61 870 participants were recruited between October 2017 and October 2019. Serum creatine kinase (CK) was measured with a Roche Cobasc 701/702 using an enzymatic rate method. Genetic testing was offered to those with a CK level of ≥ 200 U/L. For carriers of DMD variants, genetic counseling and follow up were provided.
RESULTS:
For the 61 870 females participating in the program, 1078 were found with raised serum CK (≥ 200 U/L), of which 618 (57.33%) accepted CK re-measurement after at least a two-week interval. One hundred and twenty cases were found with sustained serum CK elevation, of which 6 were confirmed to be definite DMD carriers regardless of family history. Genetic testing was provided to 33 females with a family history for DMD, and 13 were determined as definite carriers. An affected fetus was detected by prenatal diagnosis. After genetic counseling, the parents had opted induced abortion.
CONCLUSION
Large-scale DMD carrier screening through a three-step approach based on the current community health examination platform is both feasible and cost effective.

BACKGROUND:
The open reduction and internal fixation (ORIF) was a standard treatment approach for fracture at distal humerus intercondylar, whereas the optimal way before ORIF remains inconclusive. We, therefore, performed a systematic review and meta-analysis to assess the efficacy and safety of olecranon osteotomy vs. triceps-sparing approach for patients with distal humerus intercondylar fracture.
METHODS:
The electronic searches were systematically performed in PubMed, EmBase, Cochrane library, and Chinese National Knowledge Infrastructure from initial inception till December 2019. The primary endpoint was the incidence of excellent/good elbow function, and the secondary endpoints included Mayo elbow performance score, duration of operation, blood loss, and complications.
RESULTS:
Nine studies involving a total of 637 patients were selected for meta-analysis. There were no significant differences between olecranon osteotomy and triceps-sparing approach for the incidence of excellent/good elbow function (odds ratio [OR]: 1.37; 95% confidence interval [CI]: 0.69-2.75; P = 0.371), Mayo elbow performance score (weight mean difference [WMD]: 0.17; 95% CI: -2.56 to 2.89; P = 0.904), duration of operation (WMD: 4.04; 95% CI: -28.60 to 36.69; P = 0.808), blood loss (WMD: 33.61; 95% CI: -18.35 to 85.58; P = 0.205), and complications (OR: 1.93; 95% CI: 0.49-7.60; P = 0.349). Sensitivity analyses found olecranon osteotomy might be associated with higher incidence of excellent/good elbow function, longer duration of operation, greater blood loss, and higher incidence of complications as compared with triceps-sparing approach.
CONCLUSIONS
This study found olecranon osteotomy did not yield additional benefit on the incidence of excellent/good elbow function, while the duration of operation, blood loss, and complications in patients treated with olecranon osteotomy might be inferior than triceps-sparing approach.

Objective:To analyze the characteristics of prescription about Lingnan Traditional Chinese Medicine (TCM) masters for Biqiu treatment based on data mining, so as to provide reference for the clinical practice and patent drug research and development of rhinorrhea in Lingnan district.Methods:By searching journal documents and medical records in CNKI, VIP, Wanfang, Chinese BioMedical Database (SinoMed) and Duxiu Data Retrieval Platform, we selected the articles and famous TCM medical records that met the criteria on the TCM medical rules of treating Biqiu. We screened database in strict accordance with inclusion and exclusion criteria and extracted prescription information from medical cases. The software Ancient and Modern Consilia Cloud Platform (V 1.5) was used for data mining analysis and medical case standardization, and SPSS Clementine 12.0 software were used to conduct frequency statistics, association analysis and cluster analysis of drugs in medical cases. Results:A total of 31 articles and 42 medical cases including 73 prescriptions were screened. The frequency results showed that there were 40 kinds of high frequency TCMs (frequency more than 5), mainly including drugs for benefiting the qi and strengthening the spleen, medicine to relieve cold and promote nasal passages, which was the same as the frequency statistics of the effects of herbal medicine. Seven drug groups were obtained by cluster analysis. The results of rule analysis showed that 16 association rules for drug pairs and 18 association rules for 3 TCMs pairs were obtained.Conclusions:While treating allergic rhinitis, Lingnan medical doctors focus on tonifying spleen qi, dispersing wind and cold, and promoting the nasal passages, which reflect the treatment theory of cultivating earth and generating gold, and attacking and tonifying. Lingnan medical doctors commonly used Guangdong medicinal herbs, which have distinct regional characteristics. The data mining methods can comprehensively summarize and explore the potential rules of Lingnan prominent practitioners' treatment of allergic rhinitis, and provide reference for guiding the treatment of congested nose and congested nose in TCM.
