Unilateral biportal endoscopic(UBE)technique is a minimally invasive spinal technique developed rapidly in recent years.Compared with traditional spinal endoscopy,the prominent feature of UBE is that it can open two channels on the same side of the spine,which can be used to provide visual field and insert operating instruments respectively,greatly expanding the operating space and reducing the difficulty of surgery.It has the advantages of less bleeding,little injury,quick recovery and mild pain,and has unique advantages in the treatment of lumbar spinal stenosis,lumbar disc herniation and other lumbar degenerative diseases.With the continuous in-depth exploration and development of the UBE technique,the field of diseases that can be treated by this technology has gradually expanded.It is not only limited to lumbar diseases,but also has made great progress in cervical and thoracic diseases,which has attracted the attention of many spinal surgeons.UBE technique has become one of the promising surgical methods for spinal-related diseases,but there are also complications such as incomplete decompression,nerve root and dural injury,epidural hematoma,relatively prolonged operation time,operation fatigue and other deficiencies.This paper summarizes the progress of the UBE technique,discusses its complications and deficiencies,proposes relevant solutions and possible future directions for its development,so as to provide reference for the clinical practice of UBE technique.

Objective:To explore the effect of motivational enhancement group intervention conducted by nur-ses on the motivation of self-improvement,relapse tendency and self-esteem in the recovering male amphetamine addicts.Methods:Ninety-eight recovering male amphetamine addicts in the Compulsory Detoxification Center were randomly divided into control group(n=54)and motivational enhancement group(n=44).The addicts in the con-trol group received routine education while those in the motivational enhancement group received routine education combined with a 12-week motivational enhancement group intervention conducted by nurses.The Stages of Change Readiness and Treatment Eagerness Scale(SOCRATES),Relapse Tendency Questionnaire,and Rosenberg Self-es-teem Scale(RSES-T)were applied to measure the effect,before and after the intervention.Results:In both two groups,the scores of RSEST,questionnaire of relapse tendency,and self-confidence of detoxification were lower af-ter 12-week intervention than at the baseline(Ps＜0.05).After 12-week intervention,all the above scores were lower in the motivational enhancement group than in the control group(Ps＜0.05).Conclusion:Compared with routine education,the motivational enhancement group intervention conducted by nurses may be more effective to improve their self-confidence in drug rehabilitation and prevention of relapse in recovering male amphetamine ad-dicts,however,the improvement on self-esteem is limited.

Objective:To investigate the independent risk factors for postoperative severe pulmonary infection (SPI) in patients with severe traumatic brain injury (sTBI) and evaluate their predictive value.Methods:A retrospective cohort study was conducted to analyze the clinical data of 163 sTBI patients admitted to Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology from April 2021 and March 2023, including 101 males and 62 females, aged 20-80 years [53.0(46.0, 59.0)years]. The surgical procedures involved decompressive craniectomy, subdural hematoma removal, epidural hematoma removal, and intracranial hematoma removal. The patients were divided into SPI group ( n=62) and non-SPI group ( n=101) according to whether they had SPI postoperatively. The following data of the two groups were collected, including gender, age, preoperative Glasgow coma scale (GCS), elevated blood glucose, abnormal liver function, abnormal renal function, hemoglobin level, anemia, albumin level, hypoproteinemia, white blood cell count, neutrophil count, lymphocyte count, platelet count, neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI) and serum lactate dehydrogenase (LDH) level. All the hematological tests were performed on venous blood samples collected preoperatively before anti-inflammatory treatment. Independent risk factors for predicting the postoperative occurrence of SPI in sTBI patients were identified through univariate analysis and multivariable stepwise regression analysis. The predictive value of separate indicator or indicators combined was assessed by calculating the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. Results:Univariate analysis demonstrated that preoperative GCS, albumin level, lymphocyte count, NLR, PNI and serum LDH level in both groups were significantly correlated with the postoperative occurrence of SPI ( P<0.05), while gender, age, elevated blood glucose, abnormal liver function, abnormal renal function, hemoglobin level, anemia, hypoproteinemia, white blood cell count, neutrophil count, platelet count, dNLR and PLR were not correlated with the postoperative occurrence of SPI in sTBI patients ( P>0.05). Multivariable stepwise regression analysis revealed that low lymphocyte count (95% CI -0.337, -0.013, P<0.05), high NLR (95% CI -0.023, -0.005, P<0.01), low PNI (95% CI 0.007, 0.026, P<0.01), and high serum LDH (95% CI -0.002, -0.001, P<0.01) were independent risk factors for SPI in sTBI patients ( P<0.05). ROC curve analysis indicated that low lymphocyte count, high NLR, low PNI and high serum LDH level could predict SPI in sTBI patients postoperatively, with the combination of PNI and serum LDH showing the highest predictive ability (AUC=0.78, 95% CI 0.70, 0.85). Conclusion:Low lymphocyte count, high NLR, low PNI, and high serum LDH level are independent risk factors for postoperative SPI in patients with sTBI, and the combination of PNI and serum LDH possesses a high predictive value for postoperative SPI in sTBI patients.

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 regulatory role of transient receptor potential channel 6(TRPC6)on podocyte autophagy under the influence of homocysteine(Hcy)in mouse kidney.Methods Mouse renal podocytes were divided into control group and Hcy groups(stimulated by Hcy at 40,60,80 and 100 μmol/L for 48 h).The level of TRPC6 mRNA was assessed using quantitative reverse transcription polymerase chain reaction(qRT-PCR)to identify the optimal Hcy concentration for subsequent experiments.Western blotting was employed to evaluate the expression levels of autophagy-related proteins LC3 Ⅱ and p62,as well as the expression levels of podocyte structural proteins Nephrin and Podocin.The expression levels of TRPC6 mRNA and protein in both groups were determined using qRT-PCR,Western blotting and immunofluorescence.Transfections of cells with TRPC6 overexpression or interference were set as follows:(1)control group(untreated),negative control group of TRPC6 overexpression,and TRPC6 overexpression group;(2)control group(untreated),negative control group of TRPC6 interference,and TRPC6 interference group(si-1,si-2,si-3).The expression level of TRPC6 was detected using qRT-PCR.The cells after overexpressing or interfering of TRPC6 were further set as follows:(1)control group(untreated),Hcy group(80 μmol/L Hcy added),TRPC6 overexpression control+Hcy group,TRPC6 overexpression+Hcy group;(2)control group(untreated),Hcy group,TRPC6 interference control+Hcy group,and TRPC6 interference+Hcy group.The expression levels of p62,LC3 Ⅱ,and TRPC6 proteins were detected using Western blotting.Results qRT-PCR detection results showed that compared with control group,the expression level of TRPC6 mRNA in Hcy group increased with the increase of Hcy concentration,with the highest expression level observed at 80 μmol/L Hcy.Therefore,80 μmol/L Hcy was selected as the optimal concentration for intervention.At this time,the expression level of autophagy-related protein LC3 Ⅱ increased,and the expression level of p62 decreased(P<0.05).Western blotting results showed that compared with control group,the expression levels of podocyte-related proteins Nephrin and Podocin in Hcy group were significantly decreased(P<0.05).qRT-PCR results showed that compared with control group,the expression level of TRPC6 mRNA in Hcy group was significantly increased(P<0.05).Compared with negative control group for TRPC6 overexpression,both mRNA and protein expression levels of TRPC6 in TRPC6 overexpression group were significantly higher(P<0.05).Compared with negative control group for TRPC6 interference,both mRNA and protein expression levels of TRPC6 in TRPC6 interference group were significantly decreased(P<0.05).Western blotting results showed that compared with negative control group for TRPC6 overexpression,the expression level of autophagy-related protein LC3 Ⅱ in TRPC6 overexpression+Hcy group was significantly increased,and the expression level of p62 was significantly decreased(P<0.05).Compared with TRPC6 negative control+Hcy group for TRPC6 interference+Hcy,the expression level of autophagy-related protein LC3 Ⅱ in TRPC6 interference+Hcy group was significantly decreased,and the expression level of p62 was significantly increased(P<0.05).Conclusion Hcy can induce autophagy of renal podocytes.Inhibiting the expression of TRPC6 can significantly reduce the autophagy damage to podocytes.

Novel coronavirus Omicron variant infection can cause severe illness and even death in certain populations.

Objective: To explore the safety and effectiveness of stereotactic body radiation therapy (SBRT) for oligometastases from colorectal cancer (CRC). Methods: This is a prospective, single-arm phase Ⅱ trial. Patients who had histologically proven CRC, 1 to 5 detectable liver or lung metastatic lesions with maximum diameter of any metastases ≤5 cm were eligible. SBRT was delivered to all lesions. The primary endpoint was 3-year local control (LC). The secondary endpoints were treatment-related acute toxicities of grade 3 and above, 1-year and 3-year overall survival (OS) and progression free survival (PFS). Survival analysis was performed using the Kaplan-Meier method and Log rank test. Results: Petients from 2016 to 2019 who were treated in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Forty-eight patients with 60 lesions were enrolled, including 37 liver lesions and 23 lung lesions. Forty-six patients had 1 or 2 lesions, with median diameter of 1.3 cm, the median biologically effective dose (BED(10)) was 100.0 Gy. The median follow-up was 19.5 months for all lesions. Twenty-five lesions developed local failure, the median local progression free survival was 15 months. The 1-year LC, OS and PFS was 70.2% (95% CI, 63.7%~76.7%), 89.0% (95% CI, 84.3%~93.7%) and 40.4% (95%CI, 33.0%~47.8%). The univariate analysis revealed that planning target volume (PTV) and total dose were independent prognostic factors of LC (P<0.05). For liver and lung lesions, the 1-year LC, OS and PFS was 58.7% and 89.4% (P=0.015), 89.3% and 86.5% (P=0.732), 30.5% and 65.6% (P=0.024), respectively. No patients developed acute toxicity of grade 3 and above. Conclusion: SBRT is safe and effective treatment method for oligometastases from CRC under precise respiratory motion management and robust quality assurance.
