Objective To explore the efficacy of a compound nutrition preparation on wound healing after acute trauma and investigate the underlying mechanism primarily.Methods After skin wound model was successfully constructed on totally 60 male SD rats surgically,they were randomly divided into control group(CON group),whey protein group(WP group)and low-and high-dose nutritional formula groups(LDF and HDF groups),with 15 animals in per group.From the next day after surgery,the rats in each group were given corresponding nutritional interventions for 2 weeks.During the intervention,the wound conditions were observed and recorded,and the wound area was measured.The samples were collected on the 3rd,7th and 14th days after surgery,respectively.Serum albumin(ALB),prealbumin(PA),total protein(TP),inflammatory factors(TNF-α,IL-1β,IL-6 and IL-10),immunoglobulins(IgA,IgG and IgM)and hydroxyproline(Hyp)were detected by the corresponding reagent kits.The histopathologic changes of wound were observed with HE staining.Masson staining was used to observe the collagen fiber deposition in wound tissue.The angiogenesis of wound tissue was evaluated by immunohistochemical staining.Results Compared with the CON group,the wound healing speed,collagen synthesis and angiogenesis speed were significantly accelerated in the WP group,LDF group and HDF group(P＜0.05),and the effects were the most obvious in the HDF group.On the 3rd day after surgery,in the WP,LDF and HDF groups,the serum ALB,PA and TP levels were significantly increased(P＜0.05),serum TNF-α and IL-1β levels were obviously decreased(P＜0.05),and serum IL-10 level was notably increased(except WP group)when compared with the CON group.The serum IgG and IgM levels were significantly increased in the LDF group and HDF group(P＜0.05)and significant increment of IgA was only observed in the HDF group(P＜0.05).On the 7th day after modeling,the levels of ALB,PA and TP were significantly increased(P＜0.05),the levels of TNF-α,IL-1β and IL-6 were obviously decreased(P＜0.05),and the levels of IL-10 were remarkably increased(P＜0.05)in the HDF group than the CON group;The LDF group and HDF group had significantly elevated serum IgG and IgM levels(P＜0.05),but only the former group had statistically increased serum IgA level(P＜0.05).On the 14th day after modeling,the HDF group had significantly increased levels of ALB and TP(P＜0.05),decreased levels of IL-1β(P＜0.05),and raised levels of IgG and IgM when compared with the CON group(P＜0.05).Conclusion Our compound nutrition preparation promotes wound healing in rat model of acute trauma,which might be related to its improving the nutritional status,promoting collagen synthesis,and thus alleviating inflammatory response and enhancing immune function.

Objective To investigate the impact of tubeless technique on male sexual function after transurethral ureteroscopic lithotripsy.Methods 82 male patients from January 2023 to June 2023 with transethral ureteroscopic lithotripsy were selected as the study objects.Prior to surgery,39 male patients without double J tube indwelling after lithotripsy were randomly selected as the tubeless group and 43 male patients with double J tube indwelling were selected as the indwelling group by drawing lots.General clinical data and postoperative complications(lumbago,hematuria,irritation sign of bladder and fever)of the two groups were compared.The International Index of Erectile Function-5(IIEF-5)score,sexual life quality questionnaire(SLQQ)score and premature ejaculation diagnostic tool(PEDT)score of the two groups were statistically analyzed before surgery,1 month after surgery(before excutation in indwelling group),3 months and 6 months after surgery.Results Compared with the indwelling group,patients in the tubeless group had significantly fewer cases of lumbago,hematuria,and irritation sign of bladder 1 month after surgery,and the difference was statistically significant(P<0.05),but there was no significant difference in postoperative fever between the two groups(P>0.05).There were no statistically significant differences in the IIEF-5 score,SLQQ score and PEDT score between the two groups before the operation,3 months after the operation and 6 months after the operation(P>0.05).One month after the operation,the IIEF-5 score and SLQQ score of the tubeless group were significantly higher than those of the indwelling group,while the PEDT score was lower than that of the indwelling group,the differences were statistically significant(P<0.01).There were no statistically significant difference in the IIEF-5 score,SLQQ score and PEDT score at different time points in the tubeless group(P>0.05).The IIEF-5 score and SLQQ score of the indwelling group one month after the operation were significantly lower than those before the operation,while the PEDT score was significantly higher than that before the operation,the IIEF-5 score and SLQQ score of the indwelling group 3 and 6 months after the operation were significantly higher than those at 1 month after the operation,and the PEDT score was significantly lower than that at 1 month after the operation,the differences were statistically significant(P<0.01).There were statistically significant differences in the IIEF-5 score,SLQQ score and PEDT score at different time points in the indwelling group(P<0.05).Conclusion The tubeless technique after ureteroscopy has a relatively small impact on male sexual function and can significantly improve the quality of life of patients,alleviate lumbago,hematuria and irritation sign of bladder.It is worthy of clinical promotion and application.

Objective:To examine the validity and reliability of the Chinese version of the Transgender Atti-tudes and Beliefs Scale(TABS)in the general adult population.Methods:A total of 1 656 residents aged≥18 years were recruited by convenient sampling method,and were equally divided into sample 1 and sample 2 accord-ing to age group.The total sample was used for item analysis and internal consistency reliability test.Sample 1 was used for exploratory factor analysis,Sample 2 was used for confirmatory factor analysis,and 60 residents were se-lected for retesting at a 2-week interval.Results:The TABS Chinese version included a total of 26 items,with the content validity index(I-CVI)of each item ranging from 0.83 to 1.00,and the content validity index(S-CVI)of the scale being 0.98.Exploratory factor analysis extracted 3 common factors,namely interpersonal comfort,gender beliefs,and human value,with a cumulative total variance of 57.13％.Confirmatory factor analysis showed that the scale fit was acceptable(x2/df=2.95,RMSEA=0.05,GFI=0.92,AGFI=0.90).The Cronbach α coefficients of the total score of the scale and the scores of the 3 factors were 0.95,0.95,0.88 and 0.86.The retest reliabilities were 0.88,0.78,0.65 and 0.91.Conclusion:The Chinese version of the Transgender Attitudes and Beliefs Scale(TABS)has good validity and reliability in assessing general adults'attitudes toward the transgender community.

It is proposed that the brain Xuanfu and the glymphatic system(GS)have commonality in physiological structure and similarity in functions such as transporting brain substances,transmitting brain information and clearing metabolites.It is believed that GS may be the substantial manifestation of the brain Xuanfu,and GS dysfunction is the key pathological link of depression.Xuanfu stagnation and Shenji dysfunction are the core pathogenesis of depression.Taking"Brain Xuanfu-GS"as the starting point,the patho-logical mechanism of depression is deeply explored,providing a theoretical basis for the clinical diagnosis and treatment of depression in traditional Chinese medicine.

Objective:To explore the relation of depressive and anxiety symptoms to defense mechanism in transgender population.Methods:Totally 451 transgender patients in the sexual and psychological outpatient depart-ment of a hospital were selected.They were assessed with the self-Rating Depression Scale(SDS),Self-Rating Anxiety Scale(SAS)and Defense Mechanism Scale(DSQ).The SDS standard score of ≥53 was classified as having depressive symptoms,and the SAS standard score of ≥50 was classified as having anxiety symptoms.Re-sults:The detection rates of depression and anxiety were 46.8％and 28.8％respectively.Multiple linear regression analysis showed that SDS scores were positively correlated with DSQ scores of projection,conceit,complaint,with-drawal,somatization,control,isolation and identity(β=0.08-0.22),while SDS scores were negatively correlated with DSQ scores of sublimation,depression,omnipotence with incompetence and denial(0=-0.09--0.19).The SAS scores were positively correlated with the DSQ scores of projection,latent manifestation,somatization,control,isolation,identity,and consumption tendency(0=0.09-0.26),while the SAS scores were negatively cor-related with the DSQ scores of sublimation,depression,omnipotence accompanied by incompetence,and denial(β=-0.09--0.15).Conclusion:The proportion of depression and anxiety symptoms detected in the transgender group is higher,which may be related to the use of some defenses.

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 explore the differences in clinical characteristics and treatment outcomes between patients with type A and type B alcohol dependence, and to find the independent risk factors of relapse.Methods:Alcohol-dependent male patients attending the Addiction Medicine Center of Beijing Huilongguan Hospital from January 2018 to December 2020 were selected for the study and divided into type A alcohol-dependent group ( n=77) and type B alcohol-dependent group ( n=87). All patients were given acute detoxification treatment and were followed up after treatment on relapse to drinking. Differences in demographic and clinical data were compared between the two groups, and differences in treatment outcomes between the two groups at different time points over 3 months were compared. Patients were divided into relapse group and non-relapse group according to whether they drank again after 3 months. Logistic regression model was established to screen the risk factors of relapse of alcohol-dependent patients by SPSS 25.0 software. Results:There was no significant difference between the two types of patients in years of education, marital status, smoking status and working status(all P>0.05), but the proportion of co-residents( χ2=5.69, P=0.017) and the proportion of positive family history of alcoholism were significant difference between the two type of patients( χ2=13.32, P<0.001). There were statistically significant differences between the two types of patients in the onset time( t=-7.28, P<0.001), the first drinking age( t=-2.36, P=0.020), the proportion of drinking in the morning( χ2=7.83, P=0.005), psychotic symptoms( χ2=4.31, P=0.038), convulsions after withdrawal( χ2=5.30, P=0.021), and alcohol use disorder identification test(AUDIT) score( t=4.30, P<0.001). At the 4th and 8th weekend of the follow-up, there were statistically significant differences in drinking frequency(0(0, 3), 0(0, 0), Z=-4.13, P<0.001; 3(0, 3), 0(0, 3), Z=-4.42, P<0.001) and relapse rate (40(45.98%), 9(11.69%), χ2=22.92, P<0.001; 61(70.11%), 24(31.17%), χ2=24.82, P<0.001) between the two types of alcohol dependence patients after drinking again. After 12-week follow-up, there were statistically significant differences between the two types of alcohol-dependent patients in the interval of first drinking(20(7, 30)d, 88(38, 90)d, Z=-7.83, P<0.001), the cumulative duration of abstinence(4(0, 8)weeks, 12(4, 12)weeks, Z=-5.13, P<0.001), the cumulative rate of abstinence(71(81.60%), 25(32.47%), χ2=40.62, P<0.001), the frequency of drinking after abstinence(3(3, 3), 0(0, 3), Z=-5.54, P<0.001), and the reduction of daily average alcohol consumption( t=3.36, P<0.001). Logistic regression model showed that type B alcohol dependence ( OR=3.121, P=0.03, 95% CI: 1.12-8.72) and AUDIT score ( OR=1.498, P<0.01, 95% CI: 1.29-1.74) were the risk factors for relapse of alcohol-dependent patients. Conclusions:Patients with type A and type B alcohol dependence have obvious differences in clinical characteristics and treatment outcomes, and type B alcohol dependence is independent risk factor for relapse to drinking in alcohol-dependent patients, which validate the rationality and necessity of alcohol dependence subtypes.
