Objective To summarize the acupoints and parameters commonly used in the treatment of vascular cognitive impairment(VCI)by electro-acupuncture(EA)through the visual data mining technique to provide a reference basis for clinical treatment.Methods The clinical studies of EA on the treatment of VCI were searched in CNKI,Wanfang,VIP,CBM,PubMed,Embase,Cochrane Library,web of science and other major databases.The literature is managed by Note Express and the database is established by Excel.The frequency of selected acupoints,frequency,meridian tropism,parameter frequency and frequency of used acupoints are counted.Factor analysis is carried out by SPSS 21.0 software.SPSS Modeler 18.3 software is used to analyze association rules and co-occurrence network,and the analysis results are visualized by Cytoscape 3.9.1 software.Results Finally,155 papers were included,containing 155 acupoint prescriptions and 157 parameter prescriptions.Acupoint prescriptions involved 100 acupoints with a total frequency of 856 times;parameter prescriptions involved 33 parameters with a total frequency of 788 times.Conclusion At present,there is a big difference between the clinical studies,and there is no recognized acupoint and parameter for EA treatment of VCI.By further summarizing the law of EA acupuncture point and parameter,the study has sorted out the law of commonly used acupoints,meridian tropism,compounding and parameter selection for EA treatment of VCI.It was concluded that the selection of acupoints mainly started from the three aspects of deficiency,phlegm and stasis,focusing on the combination of local and distal selection of acupoints,through the identification of internal organs and meridians,to achieve the simultaneous regulation of the heart,spleen and kidney,and to take into account both the symptoms and the root cause,and to play the roles of opening the orifices to wake up mind,calming mind and benefiting intellect,strengthening the spleen and tonifying the kidneys,and invigorating blood circulation to remove stasis.The parameters of EA are recommended to be sparse and dense wave,low frequency,as tolerated by the patient,30 minutes/times,1 time/day,5 times/week as the main combinations,which can provide a certain reference basis for clinical decision-making.

Objective:To investigate the effect of interleukin-12(IL-12)on liver lesions and oxidative stress pathway in Sjo-gren's syndrome mice,and to clarify the possible mechanism of liver lesions in Sjogren's syndrome.Methods:Saliva flow rate,liver function,liver pathology and IL-12 level were measured in NOD,IL-12 knockout(IL-12KO)NOD and C57BL/6(B6)mice.Different concentrations of IL-12 and JAK2,TYK2 inhibitors were applied to mouse hepatoma cells.The oxidative stress index of mouse serum and cell culture supernatants of each group were determined.Results:Compared with the other two groups of mice,the NOD mice had significantly higher GOT and GPT(P<0.05),and decreased serum GSH-PX,SOD and CAT(P<0.05).CAT,GSH,GSH-PX and SOD were decreased,while MDA was increased in mice treated with different concentrations of IL-12.JAK2/TYK2 inhibitors reversed regulatory effects of IL-12 on SOD,GSH and MDA in hepatoma cells(P<0.05).Conclusion:IL-12 may aggravated liver damage of Sj?gren's syndrome through promoting oxidative stress of hepatocytes.

Visual hallucination(VH)is a common symptom of schizophrenia,the underlying mechanism has not been fully elucidated.It has been found that the dysfunction of dopamine(DA)system,the overactivation of α-amino-3-hydroxy-5-methyl-4-isoxazole-propionate(AMPA)receptor in glutamate system and the dysfunction of γ-aminobutyric acid(GABA)ergic neurons can induce VH in patients with schizophrenia.In addition,abnormalities in brain structural and functional networks and visual networks are also closely related to the occurrence of VH.The purpose of this paper is to review the neurochemistry and nerve injury mechanism of VH in schizophrenic patients to deeply understand the characteristics of VH,and make more accurate judgment in the early diagnosis,condition evaluation and treatment plan of schizophrenic patients.

Objective To conduct a systematic study on the potential impact of long-term specialized golf training on the three-dimensional structure of the spine in adolescent children,and to reveal the biomechanical adaptation mechanism of children's spine,providing a theoretical basis for preventing potential sports injuries caused by golf training.Methods A longitudinal observational design was adopted,with 15 male adolescent children from a golf training center selected as research subjects.Three-dimensional spinal image data were collected using digital radiography at baseline,3 months and 6 months,and dynamic monitoring and analysis were performed.Results Golf training led to a series of adaptive changes in the three-dimensional structure of children's spine,mainly reflected in significant changes in pelvic tilt distance,vertebral body offset,vertebral rotation angle,pelvic rotation angle,and pelvic torsion angle.These changes exhibited a time-effect characteristic,indicating the strong adaptability of biomechanical system of children's spine.Conclusion Golf training can cause adaptive changes in the three-dimensional structure of children's spine,highlighting the need to maintain biomechanical balances of the spine and pelvis,and to take intervention measures such as symmetrical training to prevent sports injuries,improve training quality,and prolong athletic careers.

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 investigate the application value of ultrasound technology in transurethral enucleation and resection of the prostate(TUERP).Methods:This study included 78 BPH patients admitted in our hospital from June 2021 to June 2023,aged 70.68±8.63 years and with the indication of surgery.We randomly divided them into two groups to receive TUERP(the control group,n=39)and ultrasound-assisted TUERP(the US-TUERP group,n=39).We statistically analyzed and compared the rele-vant parameters obtained before and after operation between the two groups.Results:No statistically significant differences were ob-served in the operation time and bladder irrigation time between the two groups(P>0.05).More glandular tissues were removed but less intraoperative bleeding and fewer perioperative complications occurred in the US-TUERP group than in the control.Compared with the baseline,IPSS,postvoid residual urine volume(PVR),quality of life score(QOL)and maximum urinary flow rate(Qmax)were significantly improved in both groups at 1 and 3 months after surgery,even more significantly in the US-TUERP than in the control group(P<0.05).Conclusion:US-TUERP helps achieve complete resection of the hyperplastic prostatic tissue along the surgical capsule at the anatomical level,with a higher safety,fewer perioperative complications,and better therapeutic effects.

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.

In observational studies, herbal prescriptions are usually studied in the form of "similar prescriptions". At present, the classification of prescriptions is mainly based on clinical experience judgment, but there are some problems in manual judgment, such as lack of unified criteria, labor consumption, and difficulty in verification. In the construction of a database of integrated traditional Chinese and western medicine for the treatment of coronavirus disease 2019(COVID-19), our research group tried to classify real-world herbal prescriptions using a similarity matching algorithm. The main steps include 78 target prescriptions are determined in advance; four levels of importance labeling shall be carried out for the drugs of each target prescription; the combination, format conversion, and standardization of drug names of the prescriptions to be identified in the herbal medicine database; calculate the similarity between the prescriptions to be identified and each target prescription one by one; prescription discrimination is performed based on the preset criteria; remove the name of the prescriptions with "large prescriptions cover the small". Through the similarity matching algorithm, 87.49% of the real prescriptions in the herbal medicine database of this study can be identified, which preliminarily proves that this method can complete the classification of herbal prescriptions. However, this method does not consider the influence of herbal dosage on the results, and there is no recognized standard for the weight of drug importance and criteria, so there are some limitations, which need to be further explored and improved in future research.

BACKGROUND: All-trans retinoic acid (ATRA) promotes the osteogenic differentiation induced by bone morphogenetic protein 9 (BMP9), but the intrinsic relationship between BMP9 and ATRA keeps unknown. Herein, we investigated the effect of Cyp26b1, a critical enzyme of ATRA degradation, on the BMP9-induced osteogenic differentiation in mesenchymal stem cells (MSCs), and unveiled possible mechanism through which BMP9 regulates the expression of Cyp26b1. METHODS: ATRA content was detected with ELISA and HPLC–MS/MS. PCR, Western blot, and histochemical staining were used to assay the osteogenic markers. Fetal limbs culture, cranial defect repair model, and micro–computed tomographic were used to evaluate the quality of bone formation. IP and ChIP assay were used to explore possible mechanism. RESULTS: We found that the protein level of Cyp26b1 was increased with age, whereas the ATRA content decreased. The osteogenic markers induced by BMP9 were increased by inhibiting or silencing Cyp26b1 but reduced by exogenous Cyp26b1. The BMP9-induced bone formation was enhanced by inhibiting Cyp26b1. The cranial defect repair was promoted by BMP9, which was strengthened by silencing Cyp26b1 and reduced by exogenous Cyp26b1. Mechanically, Cyp26b1 was reduced by BMP9, which was enhanced by activating Wnt/b-catenin, and reduced by inhibiting this pathway. b-catenin interacts with Smad1/5/9, and both were recruited at the promoter of Cyp26b1. CONCLUSIONS Our findings suggested the BMP9-induced osteoblastic differentiation was mediated by activating retinoic acid signalling, viadown-regulating Cyp26b1. Meanwhile, Cyp26b1 may be a novel potential therapeutic target for the treatment of bone-related diseases or accelerating bone-tissue engineering.
