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.

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 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 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 prepare chitosan/gelatin hydrogel composite hemostatic materials loaded with Panax notoginseng (PN/CMC/GMs) and evaluate their performance. Methods:PN/CMC/GMs hydrogel composite hemostatic material were prepared by the freeze-drying method, and their morphology was observed by scanning electron microscopy. Their rheological properties were observed by a rheometer. Their water absorption rate was tested by dissolution. Their biocompatibility was detected by a cytotoxicity assay. Their rapid hemostatic effect was tested using a SD rat liver hemorrhage model.Results:PN/CMC/GMs composite hemostatic materials were prepared in a lattice-like structure with certain porosity. With the increase in Panax notoginseng powder content, the modulus of PN/CMC/GMs increased accordingly, and the mechanical strength increased. PN/CMC/GMs have better water absorption and expansion functions, which can form compression hemostasis and concentrated blood to achieve rapid hemostasis, and have good biocompatibility. Hemostasis experiments showed that the hemostatic time and hemostatic effect of PN, CMC/GMs hemostatic materials on liver injury in rats were better than those of the blank control group. Conclusions:PN/CMC/GMs have good hemostatic effect and biocompatibility and have the potential for further research and clinical application.
