Objective:To evaluate the efficacy and safety of traditional Chinese medicine(TCM)in the treatment of male im-mune infertility(MII)by meta-analysis.Methods:We retrieved randomized controlled trial(RCT)on the treatment of male im-mune infertility with traditional Chinese medicine from the databases of WanFang,Chinese Biomedical Literature,Cochrane Library,Weipu,PubMed and CNKI,and performed methodological quality assessment of the RCTs identified and statistical analysis and evalua-tion of the publication bias using the RevMan5.4 software.Results:Totally,25 RCTs(2 563 cases)were included in this study.Compared with Western medicine alone in the treatment of MII,TCM achieved a significantly higher total effectiveness rate(OR=6.35,95% CI:4.96-8.13,P<0.000 01),negative conversion rate of seminal plasma anti-sperm antibodies(OR=4.52,95% CI:2.72-7.51,P<0.000 01),negative rate of serum anti-sperm antibodies(OR=2.98,95% CI:2.23-3.96,P<0.000 01),sperm concentration(MD=15.56,95% CI:11.32-19.79,P<0.000 01),grade a sperm motility(MD=3.85,95% CI:1.91-5.79,P=0.000 01),grade a+b sperm motility(MD=13.77,95% CI:7.06-20.48,P<0.000 1),sperm viability(MD=10.32,95% CI:6.78-13.86,P<0.000 01)and pregnancy rate(OR=3.53,95% CI:2.68-4.63,P<0.000 01),but a lower rate of adverse reactions(OR=0.06,95% CI:0.01-0.23,P<0.000 01).There was no statistically significant difference in the percentage of morphologically abnormal sperm between TCM and Western medicine alone in the treatment of MII(MD=-7.53,95% CI:-15.50-0.44,P=0.06).Conclusion:TCM has a definite effectiveness and high safe in the treatment of male immune infertility.

Objective To explore the effect of collaborative mode of adopting infection prevention and control(IPC)and antimicrobial stewardship(AMS)by medical institutions on reducing bacterial resistance.Methods Healthcare-associated infection(HAI)management and antimicrobial-related indicators,as well as multidrug-resis-tant organism(MDRO)detection rates of all hospitalized patients in a hospital from January 1,2015 to December 31,2022 were collected.The effectiveness of collaborative mode of IPC and AMS was evaluated.Results Compared with 2015-2016,the incidence of MDRO HAI in 2021-2022 decreased from 0.22％to 0.16％(P＜0.05),anti-microbial use density in hospitalized patients decreased from 48.48 to 42.17,antimicrobial use rate decreased from 49.45％to 45.21％(P＜0.05).The use rate of prophylactic antimicrobial agents in class Ⅰ incision surgery de-creased from 48.62％to 33.13％(P＜0.05).Compared with 2017-2018,pathogen detection rate before antimi-crobial therapy increased from 60.73％to 72.18％in 2021-2022(P＜0.05).Compared with 2015-2016,except the detection rate of vancomycin-resistant Enterococcus faecalis slightly increased in 2021-2022,detection rates of other common MDRO decreased,especially methicillin-resistant Staphylococcus aureus,carbapenem-resistant Acine-tobacter baumannii,carbapenem-resistant Pseudomonas aeruginosa,broad-spectrum β-lactamase-producing Kleb-siella pneumoniae,broad-spectrum β-lactamase-producing Escherichia coli and fluoroquinolone-resistant Escherichia coli,differences were all statistically significant(all P＜0.05).Conclusion The collaborative mode of IPC and AMS can effectively promote the rational use of antimicrobial agents,decrease the occurrence and transmission of MDRO,and decrease bacterial resistance.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To observe the efficacy and safety of flumatinib conversion in chronic myelogenous leukemia-chronicphase(CML-CP)patients with suboptimal TKI response or intolerance.Methods Patients who did not have the best response or intolerance to first-line imatinib,dasatinib,and nilotinib and switched to flumatinib(600 mg/d)from February 2020 to August 2022 were collected from 5 hospitals from Chongqing and affiliated hospitals of North Sichuan Medical College.The efficacy and safety of flumatinib were observed.The optimal response rate,major molecular response(MMR),cumulative complete cytogenetic response(CCyR)rate,cumulative MMR rate,cumulative deep molecular response(DMR),progression-free survival(PFS),event-free survival(EFS)and adverse reactions in 3,6 and 12 months after treatment were observed and analyzed.Results A total of 100 patients with CML-CP were enrolled,with a median follow-up of 18(3～36)months.The optimal response rate was 92.6％(88/95),94.4％(85/90)and 92.9％(79/85)respectively,at 3,6 and 12 months after treatment.Till August 20,2023,the cumulative CCyR and MMR rate was 98.0％(98/100)and 81.9％(77/94),respectively,the median time to reach CCyR and MMR was 3 months,and cumulative DMR rate was 51.0％(51/100).PFS rate was 100.0％(100/100)and 1-year EFS rate was 85.6％(75/90).The most common non-hematologic adverse reactions of flumatinib were diarrhea and abdominal pain(7.0％),followed by renal dysfunction(6.0％)and musculoskeletal pain(2.0％).The main hematologic adverse reactions were thrombocytopenia(12.0％),anemia(6.0％)and leukopenia(2.0％).Conclusion Flumatinib has better MMR and DMR and is well tolerated in CML-CP patients with TKI resistance or intolerance.

Protein as the allergens could lead to allergy. In addition, a widespread class of allergens were known as glycans of N-glycoprotein. N-glycoprotein contained oligosaccharide linked by covalent bonds with protein. Recently,studies implicated that allergy was associated with glycans of heterologous N-glycoprotein found in food, inhalants, insect toxins, etc. The N-glycan structure of N-glycoprotein allergen has exerted an influence on the binding between allergens and IgE, while the recognition and presentation of allergens by antigen-presenting cells (APCs) were also affected. Some researches showed thatN-glycan structure of allergen was remodeled by N-glycosidase, such as cFase I, gpcXylase, as binding of allergen and IgE partly decreased. Thus, allergic problems caused by N-glycoproteins could potentially be solved by modifying or altering the structure ofN-glycoprotein allergens, addressing the root of the issue. Mechanism of N-glycans associated allergy could also be elaborated through glycosylation enzymes, alterations of host glycosylation. This article hopes to provide a separate insight for glycoimmunology perspective, and an alternative strategy for clinical prevention or therapy of allergic diseases.

Objective To investigate the protective effect of resveratrol on intestinal barrier in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)-induced Parkinson's disease(PD)mouse models and its mechanism for regulating TLR4/MyD88/NF-κB signaling to protect dopaminergic neurons.Methods Fifty-two C57BL/6J mice were randomized into control group(n= 12),MPTP group(n=14),MPTP+resveratrol(30 mg/kg)group(n=13),and MPTP+resveratrol(90 mg/kg)group(n=13),and mouse models were established by intraperitoneal MPTP(30 mg/kg)injection for 7 days in the latter 3 groups.Behavioral tests were conducted to evaluate the effect of resveratrol on motor symptoms of the mice.Western blotting was used to detect the expression of TH,α-syn,ZO-1,Claudin-1,TLR4,MyD88,and NF-κB in the brain tissues of the mice.Immunohistochemistry,immunofluorescence,ELISA and transmission electron microscopy were used to verify the effect of resveratrol for suppressing inflammation and protecting the intestinal barrier.Results Compared with those in the normal control group,the mice in MPTP group showed significant changes in motor function,number of dopaminergic neurons,neuroinflammation,levels of LPS and LBP,and expressions of tight junction proteins in the intestinal barrier.Resveratrol treatment significantly improved motor function of the PD mice(P<0.01),increased the number of neurons and TH protein expression(P<0.05),down-regulated the expressions of GFAP,Iba-1,and TLR4,lowered fecal and plasma levels of LPS and LBP(P<0.05),restored the expression levels of ZO-1 and Claudin-1(P<0.01),and down-regulated the expressions of TLR4,MyD88,and NF-κB in the colon tissue(P<0.05).The mice with resveratrol treatment at 30 mg/kg showed normal morphology of the tight junction complex with neatly and tightly arranged intestinal villi.Conclusion Resveratrol repairs the intestinal barrier by inhibiting TLR4/MyD88/NF-κB signaling pathway-mediated inflammatory response,thereby improving motor function and neuropathy in mouse models of MPTP-induced PD.

Objective: To investigate the surgical indications and perioperative clinical outcomes of pelvic exenteration (PE) for locally advanced, recurrent pelvic malignancies and complex pelvic fistulas. Methods: This was a descriptive study.The indications for performing PE were: (1) locally advanced, recurrent pelvic malignancy or complex pelvic fistula diagnosed preoperatively by imaging and pathological examination of a biopsy; (2)preoperative agreement by a multi-disciplinary team that non-surgical and conventional surgical treatment had failed and PE was required; and (3) findings on intraoperative exploration confirming this conclusion.Contraindications to this surgical procedure comprised cardiac and respiratory dysfunction, poor nutritional status,and mental state too poor to tolerate the procedure.Clinical data of 141 patients who met the above criteria, had undergone PE in the Sixth Affiliated Hospital of Sun Yat-sen University from January 2018 to September 2022, had complete perioperative clinical data, and had given written informed consent to the procedure were collected,and the operation,relevant perioperative variables, postoperative pathological findings (curative resection), and early postoperative complications were analyzed. Results: Of the 141 included patients, 43 (30.5%) had primary malignancies, 61 (43.3%) recurrent malignancies, 28 (19.9%) complex fistulas after radical resection of malignancies,and nine (6.4%)complex fistulas caused by benign disease. There were 79 cases (56.0%) of gastrointestinal tumors, 30 cases (21.3%) of reproductive tumors, 16 cases (11.3%) of urinary tumors, and 7 cases (5.0%) of other tumors such mesenchymal tissue tumors. Among the 104 patients with primary and recurrent malignancies, 15 patients with severe complications of pelvic perineum of advanced tumors were planned to undergo palliative PE surgery for symptom relief after preoperative assessment of multidisciplinary team; the other 89 patients were evaluated for radical PE surgery. All surgeries were successfully completed. Total PE was performed on 73 patients (51.8%),anterior PE on 22 (15.6%),and posterior PE in 46 (32.6%). The median operative time was 576 (453,679) minutes, median intraoperative blood loss 500 (200, 1 200) ml, and median hospital stay 17 (13.0,30.5)days.There were no intraoperative deaths. Of the 89 patients evaluated for radical PE surgery, the radical R0 resection was achieved in 64 (71.9%) of them, R1 resection in 23 (25.8%), and R2 resection in two (2.2%). One or more postoperative complications occurred in 85 cases (60.3%), 32 (22.7%)of which were Clavien-Dindo grade III and above.One patient (0.7%)died during the perioperative period. Conclusion: PE is a valid option for treating locally advanced or recurrent pelvic malignancies and complex pelvic fistulas.
