Aim To explore the effects of Lycium berry seed oil on Nrf2/ARE pathway and oxidative damage in testis of subacute aging rats. Methods Fifty out of 60 male SD rats, aged 8 weeks, were subcutaneously injected with 125 mg • kg"D-galactosidase in the neck for 8 weeks to establish a subacute senescent rat model. The presence of senescent cells was observed using P-galactosidase ((3-gal), while testicular morphology was examined using HE staining. Serum levels of testosterone (testosterone, T), follicle-stimulating hormone ( follicle stimulating hormone, FSH ) , luteinizing hormone ( luteinizing hormone, LH ) , superoxide dis-mutase ( superoxide dismutase, SOD ) , glutathione ( glutathione, GSH) and malondialdehyde ( malondial-dehyde, MDA) were measured through ELISA, and the expressions of factors related to aging, oxidative damage, and the Nrf2/ARE pathway were assessed via immunohistochemical analysis and Western blotting. Results After successfully identifying the model, the morphology of the testis was improved and the intervention of Lycium seed oil led to a down-regulation in the expression of [3-gal and -yH2AX. The serum levels of SOD, GSH, T, and FSH increased while MDA and LH decreased (P 0. 05) . Additionally, there was an up-regulated expression of Nrf2, GCLC, NQOl, and SOD2 proteins in testicular tissue ( P 0. 05 ) and nuclear expression of Nrf2 in sertoli cells. Conclusion Lycium barbarum seed oil may reduce oxidative damage in testes of subacute senescent rats by activating the Nrf2/ARE signaling pathway.

Subjective tinnitus refers to the subjective sound perception of patients in the absence of an external sound stimulus.Tinnitus patients are often accompanied by emotional disorders, such as depression and anxiety, which seriously affect the quality of life of patients.Therefore, understanding the mechanism underlying the occurrence of tinnitus emotional disorders can help relieve the pain of tinnitus.Tinnitus was considered a simple ear disease in the early stages, but with the progress of neuroimaging technology and the development of animal models, increasing attention has been given to the changes in the neural structure and function of tinnitus patients.As a powerful technique for in vivo investigation of neural activity in the brain, multimodal magnetic resonance has been widely used in the study of subjective tinnitus.By observing the changes of brain structure in subjective tinnitus patients, the neural mechanism of the occurrence and development of tinnitus has been explored.This article reviewed recent multimodal magnetic resonance imaging studies on the neuroimaging mechanisms of tinnitus with mood disorders, compared the differences in neural activity between subjective tinnitus patients and healthy people, and found that the limbic system, default mode network and other neural network abnormalities were closely related to the mood disorders of tinnitus.The application and development of multimodal magnetic resonance techniques in subjective tinnitus were also discussed to elucidate the neural mechanism of subjective tinnitus accompanied by mood disorders with the help of multimodal magnetic resonance techniques.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

Objective: To analyze the drug resistance and genomic characteristics of a strain of serogroup O139 Vibrio cholerae producing cholera toxin isolated from the bloodstream of a person with bacteremia. Methods: The broth dilution method and automatic drug sensitivity analyzer were used to determine the antibiotic sensitivity of the strain. The complete genome sequence of the strain was obtained by using second-generation gene sequencing and nanopore sequencing. BLAST software was used for comparison and analysis with CARD, Resfinder, ISfinder, VFDB, and other databases. The drug-resistant genes, insertion sequences and virulence genes carried by the strain were identified. MEGA 5.1 software was used to construct a genetic phylogenetic tree based on the core genomic single nucleotide polymorphisms. Results: V. cholerae SH400, as the toxigenic strain, carried multiple virulence-related genes and four virulence islands. The strain was resistant to streptomycin, tetracycline and cotrimoxazole, carrying corresponding drug-resistant genes. The strain also carried IncA/C plasmid with the size of 172914 bp and contained 10 drug-resistant genes. Combined with the genomic evolutionary relationship, this study found that the drug-resistant genes and drug-resistant plasmids carried among strains showed certain aggregation. The traditional ST type of strain SH400 was ST69, and the cgMLST type was a new type highly similar to cgST-252. Conclusion: This strain of serogroup O139 V. cholerae carries the ctxAB gene, multiple drug-resistant genes and IncA/C plasmid, and there are multiple drug-resistant islands.

Objective:To investigate the effects of different concentrations of Rauwolfia extract(RE)on the proliferation of prostate cells in the rat model of benign prostatic hyperplasia(BPH).Methods:We randomly divided 48 male SD rats into six groups of an equal number,BPH model control,finasteride,low-concentration RE,medium-concentration RE,high-concentration RE and normal control,and established a BPH model in the former five groups by subcutaneous injection of testosterone propionate follow-ing castration.We treated the rats of the finasteride and RE groups intragastrically with finasteride solution at 5 mg/kg and RE at 5,10 and 20 mg/kg respectively,and those of the model control and normal control groups with an equal dose of normal saline,all once a day for 28 consecutive days.Then,we killed all the animals,collected their prostate tissue,obtained the wet weight and volume of the prostate,the prostate index and the contents of serum T and dihydrotestosterone(DHT),observed the morphological changes of the prostate tissue by HE staining,counted the glands in the prostate tissue,measured the intraglandular area,and determined the expres-sions of PCNA and α-SMA by immunohistochemistry.Results:Compared with the rats of the normal control group,the BPH model controls showed significantly increased wet weight([0.923±0.15]vs[1.455±0.52]g,P＜0.05),volume([1.035± 0.29]vs[1.687±0.31]ml,P＜0.05)and index of the prostate([0.23±0.04]％vs[0.37±0.15]％,P＜0.05),dila-tion,hyperemia and edema of the prostatic stroma and vessels,and proliferation rate of the prostatic cells,but remarkably decreased number of glands([20.35±3.83]vs[12.56±2.58],P＜0.05),epithelial thickness([39.76±5.20]vs[19.52± 1.52]μm,P＜0.05)and intraglandular area([12.3±1.21]vs[5.96±0.34]× 103 μm2,P＜0.05).In comparison with the BPH model controls,the animals treated with RE,especially in the high-concentration RE group,exhibited marked decreases in the weight([1.455±0.52]vs[0.862±0.31]g,P＜0.05),volume([1.687±0.31]vs[0.952±0.28]ml,P＜0.05)and index of the prostate([0.37±0.15]％vs[0.22±0.07]％,P＜0.05),dramatic improvement in the number of glands([12.56±2.58]vs[18.36±1.25],P＜0.05),epithelial thickness([39.76±5.20]vs[19.04±3.89]μm,P＜0.05)and intraglandular area([5.96±0.34]vs[10.25±0.98]× 103μm2,P＜0.05],P＜0.05),remarkable down-regula-tion of the expressions of PCNA and α-SMA,and significant reduction of the contents of serum T([19.147±3.214]vs[6.016± 1.978]ng/ml,P＜0.05)and DHT([9.052±0.633]vs[2.532±0.386]ng/ml,P＜0.05).Conclusion:Rauwolfia ex-tract can inhibit the proliferation of prostate cells and relieve BPH symptoms in a concentration-dependent manner in rats with BPH.

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

OBJECTIVE: To investigate the clinical effect of Kinesio Taping combined with electroacupuncture in the treatment of Bigliani typeⅠsubacromial impingement syndrome. METHODS: From January 2019 to June 2021, 82 cases with Bigliani typeⅠsubacromial impingement syndrome were selected and divided into treatment group and control group. Treatment group included 41 cases, 23 males and 18 females, aged from 20 to 52 years old, with an average of (39.31±5.80)years old. There were 12 cases on left shoulder and 29 cases on right shoulder. The course of disease was from 3.2 to 35.4 months. The treatment group was treated with Kinesio Taping and electroacupuncture. In control group, there were 41 cases, including 22 males and 19 females, aged from 19 to 53 years old with an average of (40.67±6.13) years old, 30 cases on right shoulder, 11 cases on left shoulder. The courses of disease was from 3.0 to 36.0 months. The control group was treated with simple shoulder electroacupuncture. Patients in both groups were treated with electroacupuncture 3 times a week for 3 weeks. After each electroacupuncture treatment in the treatment group, the Kinesio Taping was applied immediately and kept for 2 days. Before treatment, immediately after treatment, and after 1, 3, 8 weeks, the shoulder joint Constant-Murley score, pain visual analogue scale (VAS), and shoulder joint range of motion were used to evaluate the treatment effect. RESULTS: After 1 week of treatment, there was 1 patient in treatment group refused treatment due to hypersensitivity to Kinesio Taping, 1 patient in control group was allergic to the metal needle and refused treatment. And the other 80 patients completed all treatment. Immediately after treatment, and 1, 3, and 8 weeks after treatment, VAS of treatment group were (2.06±1.03), (2.74±1.66), (3.28±1.04), and (3.90±0.12) points, respectively. The Constant-Murley scores of shoulder joint were(86.41±3.52), (82.44±3.14), (80.46±2.54), (76.97±2.01) points. VAS of control group were(3.35±0.41), (3.08±0.92), (3.77±0.67), (3.96±1.04) points, and the Constant-Murley scores of the shoulder joint were(75.82±2.73), (74.72±1.53), (73.66±1.53), (70.68±1.95) points respectively. Immediately after treatment, VAS, Constant-Murley score, and shoulder range of motion between two groups were better than those of before treatment (P<0.05), and the difference was statistically significant between two groups after treatment (P<0.05). One week after treatment, VAS, Constant-Murley score, and shoulder joint range of motion between two groups were better than those of before treatment (P<0.05), but there was no significant difference in VAS between two groups (P>0.05). There were significant differences in the Constant-Murley score and shoulder range of motion between two groups (P<0.05). At 3 and 8 weeks after treatment, VAS, Constant-Murley score, and the range of motion of shoulder joints between two groups were better than those of before treatment (P<0.05), but there was no significant difference between two groups(P>0.05). CONCLUSION The treatment for bigliani typeⅠsubacromial impingement syndrome with Kinesio Taping combined with electroacupuncture can reduce pain, effectively improve the function of shoulder joint. In addition, with Kinesio Taping protection when motion, the patients sports ability can be improved obviously, with good immediate effect, and no trauma. If the patients are willing to accept it, it would be an immediate and effective treatment.

To systematically review the efficacy of Xuebijing Injection combined with western medicine in the treatment of systemic inflammatory response syndrome(SIRS). In this study, CBM, CNKI, Wanfang, VIP, PubMed and EMbase databases were retrieved for clinical randomized controlled trials on the effect of Xuebijing Injection combined with western medicine in the treatment of SIRS from the establishment of the database to July 31, 2020. After screening, Meta-analysis was conducted by RevMan 5.3 software, trial sequential analysis was conducted by TSA 0.9.5.10 beta software, and the evidence quality level was evaluated by GRADEprofiler 3.6.1 software. Meta-analysis showed that Xuebijing Injection combined with western medicine could reduce white blood cell count(MD=-2.32, 95%CI[-2.44,-2.21], P<0.000 01), C-reactive protein count(MD=-22.70, 95%CI[-29.61,-15.79], P<0.000 01), APACHE Ⅱ score(MD=-2.15, 95%CI[-2.43,-1.87], P<0.000 01), tumor necrosis factor alpha count(SMD=-1.23, 95%CI[-1.48,-0.99], P<0.000 01) and interleukin-6 count(SMD=-0.92, 95%CI[-1.15,-0.69], P<0.000 01), improve treatment efficiency(RR=1.39, 95%CI[1.23, 1.56], P<0.000 01), reduce incidence of multiple organ dysfunction(RR=0.47, 95%CI[0.35, 0.64], P<0.000 01) and mortality(RR=0.22, 95%CI[0.13, 0.37], P<0.000 01), which were better than western medicine treatment alone. Trial sequential analysis showed that in terms of reducing the incidence of multiple organ dysfunction and C-reactive protein count, the cumulative Z value passed through the traditional threshold, TSA threshold and expected information value, and reached the required number of cases. GRADE evaluation showed that the level of evidence was low or very low. According to the findings, Xuebijing Injection combined with western medicine is effective in treating SIRS. However, as the low quality of the included studies may affect the reliability of the conclusion, more high-quality studies shall be included for further verification in the future, so as to provide better suggestions for clinical medication.
