Metastasis is a key cause of death in tumor patients, and a number of tumor patients have comorbid psychosomatic abnormalities and are in a state of chronic stress. Chronic stress affects the release of many kinds of hormones and neurotransmitters, such as epinephrine, norepinephrine, dopamine, glucocorticoids, cortisol, sex hormones, etc., through the hypothalamus–pituitary–adrenal axis and sympathetic nervous system. These substances can act on the β-adrenergic receptor, glucocorticoid receptor, etc., on tumor cells, immune cells, and other cells in the tumor microenvironment and promote the tumor progression and metastasis by directly enhancing the invasive and metastatic ability of tumor cells, inducing the formation of the immunosuppressive microenvironment and promoting tumor angiogenesis and other pathways. Antipsychotic drugs, β-blockers, and glucocorticoid receptor antagonists have inhibitory effects on chronic stress-mediated tumor metastasis and have achieved certain clinical efficacy. Relevant studies have been carried out on traditional Chinese medicine decoctions and monomers, which can inhibit tumor metastasis by modulating the immune microenvironment and reversing chronic stress-mediated hormonal changes. The psychological problems of tumor patients have gradually received attention, and the development of new anti-metastatic drugs based on the mechanism of action of chronic stress in promoting tumor progression and metastasis provides new ideas for the improvement of the overall efficiency of tumor prevention and treatment.

AIM:To study the expression of glucose transporters(GLUTs)and silent information regulators(SIRTs/sirtuins)in the liver of diabetic rats and human hepatocytes(LO2 cells)treated with high glucose.METHODS:(1)Twenty male SD rats were randomly divided into normal control(NC)group and diabetes mellitus(DM)group.The rats in DM group were given single intraperitoneal injection of streptozotocin(STZ,60 mg/kg)to establish the DM model,while the rats in NC group were intraperitoneally injected with equal volume of solvent once.Fasting blood glucose(FBG)and body mass were measured every 2 weeks.After 12 weeks of rearing,the blood and liver tissues of the rats were ob-tained after anesthesia with 1%sodium pentobarbitone,the biochemical indicators of blood were detected,and the liver in-dex was calculated.Hematoxylin-eosin(HE)staining and periodic acid-Schiff(PAS)staining were used to observe liver histopathological changes.Lipid accumulation in liver tissues was detected by oil red O staining.The expression levels of GLUTs and SIRTs family member proteins were detected in rat liver tissues.(2)The LO2 cells were treated with different concentrations of glucose for 48 h.The viability of the cells in each group was measured by CCK-8 assay,and Western blot was used to detected the protein expression levels of GLUTs and SIRTs in the cells.RESULTS:(1)Compared with NC group,the rats in DM group were depressed,lost weight,and the FBG and liver index were significantly increased(P＜0.05).The results of HE staining showed that the hepatic sinuses were dilatated and congested near the central vein in DM rats,and mild edema and scattered infiltration of inflammatory cells were found in liver cells.The results of oil red O staining showed the red fat droplets were diffusely scattered within liver cells in DM group.The results of PAS staining showed that there were numerous diffuse light purple circular droplets in the cytoplasm of the liver cells in the central ve-nous area of the DM rats.Western blot showed that the protein levels of GLUTs were higher and the protein levels of SIRTs were lower than those in NC group(P＜0.01).(2)The results of CCK-8 assay showed that the viability of LO2 cells was increased in 50 mmol/L glucose group(P＜0.01),without significant difference in 75,100 and 125 mmol/L glucose groups(all P＞0.05),and decreased in 150,175 and 200 mmol/L glucose groups(all P＜0.01).Later,150 mmol/L glu-cose was used as the high-glucose intervention condition.Western blot showed that the protein levels of GLUTs and SIRTs in LO2 cells under high glucose intervention were consistented with the results in animal experiments.CONCLUSION:High concentration of glucose can cause liver damage in SD rats and reduce the viability of human hepatocytes(LO2 cells).It can also increase the expression of GLUTs and decrease the expression of SIRTs in rat liver tissues and LO2 cells.Therefore,GLUTs and SIRTs family members may be the target proteins of diabetes-induced liver injury.

BACKGROUND:Early identification of patients requiring ventilator support will be beneficial for the outcomes of botulism.The present study aimed to establish a new scoring system to predict mechanical ventilation(MV)for botulism patients. METHODS:A single-center retrospective study was conducted to identify risk factors associated with MV in botulism patients from 2007 to 2022.Univariate analysis and multivariate logistic regression analysis were used to screen out risk factors for constructing a prognostic scoring system.The area under the receiver operating characteristic(ROC)curve was calculated. RESULTS:A total of 153 patients with botulism(66 males and 87 females,with an average age of 43 years)were included.Of these,49 patients(32.0%)required MV,including 21(13.7%)with invasive ventilation and 28(18.3%)with non-invasive ventilation.Multivariate analysis revealed that botulinum toxin type,pneumonia,incubation period,degree of hypoxia,and severity of muscle involvement were independent risk factors for MV.These risk factors were incorporated into a multivariate logistic regression analysis to establish a prognostic scoring system.Each risk factor was scored by allocating a weight based on its regression coefficient and rounded to whole numbers for practical utilization([botulinum toxin type A:1],[pneumonia:2],[incubation period≤1 day:2],[hypoxia<90%:2],[severity of muscle involvement:grade II,3;grade III,7;grade IV,11]).The scoring system achieved an area under the ROC curve of 0.82(95%CI 0.75-0.89,P<0.001).At the optimal threshold of 9,the scoring system achieved a sensitivity of 83.7%and a specificity of 70.2%. CONCLUSION:Our study identified botulinum toxin type,pneumonia,incubation period,degree of hypoxia,and severity of muscle involvement as independent risk factors for MV in botulism patients.A score≥9 in our scoring system is associated with a higher likelihood of requiring MV in botulism patients.This scoring system needs to be validated externally before it can be applied in clinical settings.

Objective To investigate the effects of microsurgical varicocelectomy on testicular function and sexual function in patients with varicocele.Methods The clinical data of 90 patients with varicocele admitted to our hospital were retrospectively analyzed,and the patients were divided into the laparoscopic group(received laparoscopic varicocelectomy)and the microscopic group(received microsurgical varicocelectomy)according to different surgical methods,with 45 cases in each group.The testicular function and sexual function related indexes including sperm density,normal sperm ratio,rate of sperm motility(grades a+b),forward motility sperm rate,international index of erectile function-5(IIEF-5)score,and the levels of testosterone,follicle-stimulating hormone,luteinizing hormone,and androgen levels before and 6 months after surgery in the two groups were compared.The incidence of complications and recurrence 6 months after surgery in the two groups were counted.Results Compared with those before surgery,the sperm density,forward motility sperm rate,rate of sperm motility(grades a+b),normal sperm ratio,IIEF-5 score,testosterone level,and androgen level 6 months after surgery of patients in the two groups were significantly increased(P<0.05),and the levels of luteinizing hormone and follicle-stimulating hormone were decreased(P<0.05).Compared with the laparoscopic group,the levels of follicle-stimulating hormone and luteinizing hormone,and incidence of complications 6 months after surgery of patients in the microscopic group were decreased(P<0.05),and the levels of testosterone and androgens,and IIEF-5 score 6 months after surgery were increased(P<0.05).There was no significant difference in the recurrence rate between the two groups(P>0.05).Conclusion Microsurgical varicocelectomy can improve the testicular function and sexual function of patients with varicocele,with a low incidence of complications.

Acute kidney injury （AKI） is a clinical syndrome characterized by a rapid decline in renal function over a short period due to various etiologic factors. If left untreated， AKI can progress to chronic kidney disease （CKD） or even end-stage renal disease （ESRD）. Although continuous renal replacement therapy （CRRT） can manage severe AKI， effective pharmacological treatments for AKI remain largely unavailable. Chinese medicine， with its multi-target and multi-pathway approaches， has accumulated substantial theoretical and practical knowledge in treating AKI and related complications. Rehmanniae Radix is a commonly used Chinese medicinal， known for its functions in clearing heat， cooling blood， nourishing yin， and promoting fluid production. The primary active ingredients of Rehmanniae Radix include catalpol， acteoside， and aucubin. In this study， we summarized recent research on the effect of the active ingredients of Rehmanniae Radix in preventing and treating AKI. We found that the key mechanisms underlying its anti-AKI effects include amelioration of inflammation， alleviation of oxidative stress， and inhibition of apoptosis. Additionally， the antifibrotic properties of the active ingredients of Rehmanniae Radix suggest its potential in slowing CKD progression. We reviewed the mechanisms of Rehmanniae Radix in treating AKI and its antifibrotic effects to provide a scientific basis for developing new AKI drugs， promoting the utilization of Rehmanniae Radix resources， and reducing the transition from AKI to CKD.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

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 evaluate the safety and efficiency of China-made Toumai Robot-assisted laparoscopic radical prosta-tectomy(LRP).Methods:This study included 40 cases of PCa treated from January 2023 to May 2023 by robot-assisted LRP with preservation of the bladder neck and maximal functional urethral length,15 cases with the assistance of Toumai Robot(the TMR group)and the other 25 with the assistance of da Vinci Robot as controls(the DVR group).We recorded the docking time,laparo-scopic surgery time,vesico-urethral anastomosis time,intraoperative blood loss and postoperative urinary continence,and compared them between the two groups.Results:Operations were successfully completed in all the cases.No statistically significant differ-ences were observed between the TMR and DVR groups in the docking time(6 min vs 5 min,P＞0.05)or intraoperative blood loss(200 ml vs 150 ml,P＞0.05).The TMR group,compared with the DVR group,showed a significantly longer median laparoscopic surgery time(146 min vs 130 min,P＜0.05)and median vesico-urethral anastomosis time(19 min vs 16 min,P＜0.05).There were no statistically significant differences between the TMR and DVR groups in the rates of urinary continence recovery immediately af-ter surgery(60.0％[9/15]vs 64.0％[16/25],P＞0.05)or at 1 month(80.0％[12/15])vs(76.0％[19/25],P＞0.05),3 months(93.3％[14/15])vs(92.0％[23/25],P＞0.05)and 6 months postoperatively(100％[15/15])vs(96％[24/25],P＞0.05).Conclusion:China-made Toumai? Robot surgical system is safe and reliable for laparoscopic radical prosta-tectomy,with satisfactory postoperative recovery of urinary continence.

Objective:To explore the application of modified scrotoscopic surgery(MSS)in the treatment of testicular hydro-cele.Methods:We selected 45 cases of testicular hydrocele for this study,22 treated by traditional scrotoscopic surgery(TSS)and the other 23 by MSS,which was performed with a pin-shaped electrode bent inward at an angle of 60° instead of a circular electrode used in TSS.We recorded the general clinical data,operation time,incision length,intraoperative injury,incision infection,scrotal e-dema,postoperative hospital stay and postoperative Visual Analogue Scale(VAS)scores of the patients and compared them between the two groups.Results:There was no statistically significant difference in the general clinical data between the two groups(P＞0.05).Compared with the patients of the TSS group,those of the MSS group showed significantly shorter operative time([32.86±3.80]vs[26.13±2.81]min,P＜0.05),incision length([14.09±2.23]vs[8.73±1.48]mm,P＜0.05)and postopera-tive hospital stay([4.36±1.05]vs[2.00±0.90]d,P＜0.05),and achieved remarkably lower VAS scores on postoperative days 1(4.41±1.05 vs 3.09±0.79,P＜0.05),2(3.36±1.05 vs 2.78±1.13,P＜0.05),3(2.65±0.72 vs 1.74±0.86,P＜0.05)and 7(1.91±0.81 vs 1.04±0.82,P＜0.05).At 3 and 7 days after surgery,scrotal edema was markedly mil-der in the MSS than in the TSS group(P＜0.05).No testicular or epididymal damage,or wound infection occurred in either of the two groups.Conclusion:MSS is safe and effective in the treatment of testicular hydrocele,superior to TSS for its advantages of shorter operation time,smaller surgical incision,less postoperative pain and milder scrotal edema.
