In today's society， depression is a kind of highly prevalent chronic mental illness. It leads to a high disability rate and a heavy economic burden. Depression is defined by fundamental symptoms of low mood and diminished pleasure. Its causes and mechanisms remain unclear， and it presents a broad spectrum of symptoms and a persistent nature that significantly impacts both physical and mental well-being. Treatment in Western medicine primarily focuses on alleviating symptoms， yet it entails numerous adverse effects and contraindications. Traditional Chinese medicine （TCM） treatment is based on resolving depression， which is often accompanied by soothing liver， and the key medicine is Bupleuri Radix. Bupleuri Radix associated prescriptions refer to a class of prescriptions using Bupleuri Radix as the sovereign medicinal or having a high dose of Bupleuri Radix， which are widely used in the field of anti-depression. Previous studies from animal experiments， clinical research， and modern pharmacological research have confirmed that Bupleuri Radix associated prescriptions have precise anti-depression efficacy in multiple ways and at multiple levels， but lack a comprehensive and systematic summarization. This paper summarized and analyzed the literature related to the clinical application and mechanism of action of Bupleuri Radix associated prescriptions in anti-depression treatment. The results showed that the anti-depression mechanism of the Bupleuri Radix associated prescriptions （such as Xiaochaihu Tang， Xiaoyao San， Sini San， Chaihu Shugan San， and Chaihu jia Longgu Muli San） was associated with the effects of regulating monoamine neurotransmitters， the brain-derived neurotrophic factor （BDNF）， intestinal flora， and the hypothalamic-pituitary-adrenal （HPA） axis， inhibiting inflammatory responses， and modulating related signaling pathways. Applying them in clinical practice can effectively alleviate patient symptoms， lower the TCM syndrome score and the severity of depression， and also reduce adverse reactions. This underscores advantages of TCM in depression treatment， which offers patients a secure， effective， and more individualized alternative treatment regimen. On this basis， the shortcomings of current studies and the future trend were analyzed. This study aimed to provide an evidence-based medicine basis for the research and development of novel antidepressant medications.

Objective To explore the effects of spermary on sexual behavior,gonadal development and sperm count production.Methods Fifty-six male zebrafishes of 10-month-old AB strain after fertilization were randomly divided into 7 tanks and set up as the normal group,model group,positive control group(clomiphene citrate group,Wuzi Yanzong Pills group),and Spermary low,medium and high concentration groups,8 fishes in each group.Except for the normal group,cyclophosphamide was given in water solution to establish the zebrafish oligospermia model,respectively.On 9 d of modeling,the positive control group was ad-ministered at a concentration of 0.1 μg/mL in the clomiphene citrate group and 6 μg/mL in the Wuzi Yanzong Pill group;the spermary low,medium and high concentration groups were administered at 200,300,900 μg/mL,respectively.On 16 d of modeling,the normal female zebrafishes were placed in the culture tank of each group in a 1∶1 ratio,and the frequency of tail-chasing was observed and recorded in male and female fishes.The body length,weight,testis weight and sperm count were measured and the statistical analysis was performed by comparing the differences among the groups before and after drug administration(one-way ANOVA).Results Com-pared with the normal group,the frequency of tail-chasing of zebrafishes,body length,body weight,testis weight and sperm count in the model group were significantly decreased(P＜0.05).Compared with the model group,the frequency of tail-chasing of zebrafishes,body length,body weight,testis weight and sperm count in the spermary low,medium and high concentration groups all were significantly increased(P＜0.05),in which the vitality change of sexual behavior in the spermary medium concentration group was most obvious,and the increase of sperms count was most obvious.Conclusion A certain dose of spermary could effectively promote the sexual behavior,gonadal development and sperm count production in male zebrafish with oligospermia.The efficacy of spermary in enhancing the male sexual function and treating oligozoospermia and infertility de-serves to be studied.

Objective To investigate the mechanism and protective effect of Humanin(HN)on rotenone(Rot)-induced toxic damage for dopamine neurons.Methods The Rot-poisened PC12 cell model was constructed,and the control group,the Rot poisening group,the HN pretreated Rot poisening group,and the HN treatment group were set up.ELISA was used to detect the content of HN inside and outside of Rot-infected cells,CCK-8 assay was used to detect cell viability,and ATP detection kit was used to detect the intracellular ATP content.Dichloro-dihydro-fluorescein diacetate(DCFH-DA)assay was used to detect the level of reactive oxygen species(ROS)in cells.Western blotting was performed to detect the expression level of mitochondrial autophagy regulatory proteins Pink1,Parkin,p62,LC3,mitochondrial biogenesis regulatory protein PGC1α,division/fusion regulatory proteins OPA1,MFN2,DRP1,p-DRP1 and antioxidant stress regulatory proteins Keap1 and Nrf2.HBAD-mcherry-EGFP-LC3 adenovirus transfected cells was used to observed the number of autophagosomes and autophagolysosomes.Results The results showed that the intracellular concentration of HN in PC12 in the Rot poisening group was significantly higher than that in the control group(P＜0.05);Compared with the control group,the Rot poisening group had significantly decreased activity of PC12 cells,decreased ATP content and increased production of ROS.After the poisen of Rot in PC12 cells,the expression of Pink1 and p-Parkin,the ratio of LC3Ⅱ/LC3Ⅰ and the expression of p-DRP1 in mitochondrial fusion protein was increased,while the expression of p62,the expression of mitochondrial biogenesis protein PGC1 α,mitochondrial fusion proteins MFN2 and OPA1,and antioxidant stress proteins Keap1 and Nrf2 were decreased(all P＜0.05).The number of autophagosomes and autophagolysosomes in PC12 cells in the Rot poisening group was higher than that in the control group(P＜0.05),and HN pretreatment(20 μmol/L)could significantly improve the changes mentioned above caused by Rot poisening(P＜0.05).Conclusion HN ameliorates Rot-induced toxic damage for dopamine neurons by inhibiting mitophagy and mitochondrial division and promoting mitochondrial biogenesis and fusion,and anti-oxidative stress.

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 analyze the changing prevalence and resistance profiles of multiple drug-resistant(MDR)bacteria in Minhang Hospital of Fudan University before and after the onset of COVID-19 pandemic.Methods The resistance profiles of 6 bacterial species were compared before(2017-2019)and after(2020-2022)the onset of COVID-19 pandemic.WHONET 5.6 software was used to statistically analyze the data of antimicrobial susceptibility testing.Results After the onset of COVID-19(2020-2022),the prevalence of carbapenem-resistant Klebsiella pneumoniae(CRKP)was significantly higher than that in the pre-pandemic period(2017-2019)(40.1％vs 27.9％,P＜0.01),while the prevalence of carbapenem-resistant Escherichia coli(CREC)decreased significantly(1.9％vs 3.1％,P＜0.05).The prevalences of carbapenem-resistant Acinetobacter baumannii(CRAB),carbapenem-resistant Pseudomonas aeruginosa(CRPA),methicillin-resistant Staphylococcus aureus(MRSA),and vancomycin-resistant Enterococcus(VRE)did not show significant difference before and after the onset of COVID-19 pandemic.MDR isolates were mainly isolated from respiratory tract samples either before or after COVID-19 pandemic(78.4％vs 78.5％).The prevalence of MDR in the intensive care unit(ICU)was significantly higher during the period from 2020 to 2022 compared to the pre-pandemic period(53.1％vs 35.5％,P＜0.01).The resistance rate of MRSA to methoprim-sulfamethoxazole decreased from 15.7％during 2017-2019 to 3.5％during 2020-2022(P＜0.01).Compared to the pre-pandemic period,the E.faecalis strains showed lower resistance rates to penicillin G,ampicillin,and levofloxacin during 2020-2022.The resistance rate of E.faecium to high-level gentamicin decreased significantly from 50.1％during 2017-2019 to 39.2％during 2020-2022(P＜0.01).The resistance rate of E.coli to imipenem decreased from 2.7％to 1.2％(P＜0.01),while A.baumannii and P.aeruginosa strains showed stable resistance rates to carbapenems(P＞0.05).Conclusions After the onset of COVID-19 pandemic,the prevalence of CREC decreased significantly.The prevalences of CRAB,CRPA,MRSA,and VRE also showed a decreasing trend.However,the prevalence and resistance rates of CRKP significantly increased.It is necessary to strengthen hospital infection control measures to curb the spread of MDR bacteria.

Objective:To analyze potential roles of mechanical stress in the formation of plantar melanoma.Methods:A retrospective analysis was conducted on 129 cases of plantar melanoma in Xiangya Hospital, Central South University between 2014 and 2021, and the distribution and clinical characteristics of plantar melanoma were analyzed. The goodness-of-fit test was used to compare the distribution of plantar melanoma between weight-bearing areas (the toes, forefoot, lateral midfoot, heel) and non-weight-bearing areas of the foot (the arch) , while t test, Fisher′s exact test and Wilcoxon rank sum test were used to analyze differences in clinicopathological characteristics of plantar melanoma between weight-bearing areas and non-weight-bearing areas of the foot. Results:Among the 129 patients with plantar melanoma, 66 (51.2%) were males and 63 (48.8%) were females, and their age at onset was 60.6 ± 13.1 years. Plantar melanoma mostly occurred on the heel (65 lesions, 1.31 lesions per square centimeter) , followed by the forefoot (31 lesions, 0.41 lesions per square centimeter) , the bottom of the toes (15 lesions, 0.43 lesions per square centimeter) , lateral midfoot (11 lesions, 0.38 lesions per square centimeter) and the arch of foot (7 lesions, 0.16 lesions per square centimeter) . The goodness-of-fit test showed that melanoma was more prone to occur in the weight-bearing areas than in the non-weight-bearing areas ( χ2 = 66.59, P < 0.001) ; compared with the arch of foot, a higher incidence density was observed in the heel and forefoot ( χ2 = 38.29, 5.23, P < 0.001, = 0.022, respectively) . There were no significant differences in the gender ratio, age and occupation of patients, prevalence rates of left/right foot involvement, Breslow thickness, ulceration status, Clark grades, lymph node metastasis rate, and stages between melanomas in the weight-bearing areas and those in non-weight-bearing areas (all P > 0.05) . Conclusion:Plantar melanoma was more prone to occur in the weight-bearing areas than in the non-weight-bearing areas, suggesting that mechanical stress may be related to the occurrence and development of melanoma.

Objective:To investigate the application value of early and late interventional embolization in intracranial aneurysms.Methods:Eighty-two patients with intracranial aneurysm who received treatment in Wenzhou People's Hospital from October 2015 to February 2020 were included in this study. These patients were divided into early (≤ 3 days) and late (> 3 days) groups, with 41 patients in each group, according to time from disease onset to surgery. The early group was subjected to early interventional embolization, and the late group was treated with late interventional embolization. The effects of embolization and National Institutes of Health Stroke Scale score pre- and post-treatment, as well as modified Barthel index, Mini-Mental State Exam score, matrix metalloproteinase-9 level, and soluble intercellular adhesion molecule-1 level post-treatment and prognosis were compared between the two groups.Results:The embolization effects in the early group were statistically superior to those in the late group ( P = 0.046). After treatment, National Institutes of Health Stroke Scale score in the early group was significantly lower than that in the late group [(4.02 ± 1.64) points vs. (6.81 ± 2.02) points, t = 6.86, P < 0.01]. Mini-Mental State Exam score and modified Barthel index in the early group were (28.09 ± 1.35) points and (81.12 ± 9.67) points, respectively, which were significantly higher than (26.01 ± 1.19) points and (73.02 ± 8.19) points in the late group ( t = 7.40, 4.09, both P < 0.001). After treatment, matrix metalloproteinase-9 and soluble intercellular adhesion molecule-1 levels in the early group were (420.33 ± 29.40) μg/L and (403.70 ± 23.28) ug/L, respectively, which were significantly lower than (491.30 ± 31.19) μg/mL and (496.37 ± 30.46) μg/L in the late group ( t = 10.60, 15.47, both P < 0.001). Prognosis in the early group was superior to that in the late group ( P = 0.049). Conclusion:Early interventional embolization has better efficacy than late interventional embolization in the treatment of intracranial aneurysm. The former can effectively improve neurological function and mental state, enhance living ability, and improve prognosis, which may be related to the regulation of matrix metalloproteinase-9 and soluble intercellular adhesion molecule-1 levels.

Objective:To investigate the efficacy of TiRobot navigation combined with ankle arthroscopy in the reduction and internal fixation of Hawkins type Ⅱ talus neck fracture.Methods:From January 2019 to September 2020, a total of 13 patients with Hawkins type Ⅱ talus neck fracture were admitted to Department of Foot and Ankle Surgery, Xuzhou Renci Hospital. They were 8 males and 5 females, with a mean age of 35.8 years (from 22 to 61 years). All fractures were reduced and fixated using TiRobot navigation combined with ankle arthroscopy. Time for fracture reduction assisted by intraoperative arthroscopy, time for internal fixation assisted by TiRobotic navigation, fracture union time and complications were recorded. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was used at the last follow-up to evaluate the functional outcomes.Results:All the operations were finished within 2 hour. The primary screw placement succeeded in all. The time for fracture reduction assisted by intraoperative arthroscopy averaged 52.8 min (from 43 to 66 min) and the time for internal fixation assisted by TiRobotic navigation 43.6 min (from 33 to 55 min). All the patients were followed up for an average 13.3 months(from 12 to 15 monhs). They obtained bony union within 3 months. One patient developed traumatic subtalar arthritis with mild pain and was treated conservatively. None of the patients had complications like incision infection or talus necrosis. The average AOFAS ankle-hindfoot score was 91.0 points (from 83 to 94 points) at the last follow-up.Conclusion:In the reduction and internal fixation of Hawkins type Ⅱ talus neck fracture, TiRobot navigation combined with ankle arthroscopy shows advantages of minimal invasion, accurate reduction and screw placement, and limited complications, leading to fine short-term functional outcomes.
