This article combined the pathogenic characteristics of "latent wind" with the theory of collateral diseases to clarify the pathological features of tumor blood vessels， including their active proliferation， high permeabi-lity， and promotion of metastasis. The theory framework of "latent wind in collaterals" as the tumor mechanism was proposed， which suggests that at the site of tumor lesions， the collaterals inherit the nature of latent wind to grow excessively， adopt an open and discharge nature to leak essence， and tumor toxins， characterized by their rapid movement and frequent changes， spread and metastasize， driving the progression of malignant tumors. Focusing on the fundamental pathogenesis of "latent wind in collaterals"， specific clinical treatment principles and methods centered on treating wind are proposed， including regulating qi and dispelling wind， clearing heat and extinguishing wind， unblocking collaterals and expelling wind， and reinforcing healthy qi to calm wind， so as to provide references for enhancing the precision of traditional Chinese medicine in treating malignant tumors.

AIM:To observe the effect of opioid-free anesthesia with esketamine on delirium after hip replacement surgery in elderly patients.METH-ODS:One hundred and fourteen elderly patients who underwent hip replacement were randomly di-vided into two groups:opioid-free anesthesia(OFA)group and opioid anesthesia(OA)group(n=57).During anesthesia induction and maintenance,es-ketamine was administered in OFA group,and that fentanyl and remifentanil were administered in OA group.Delirium was mainly recorded within 3 days after the surgeries,and the patients'delirium sta-tus was evaluated using the Chinese Revised Deliri-um Diagnostic Scale(CAM-CR).RESULTS:The pa-tients in OFA group had lower CAM-CR scores and delirium incidence compared to those in the OA group at 2 days after surgery.CONCLUSION:Opioid-free anesthesia based on esketamine can effective-ly reduce delirium after hip replacement in elderly patients.

Objective:To compare the efficacy of internal fixation using cannulated screw combined with fibular allograft and internal fixation using cannulated screw alone in the treatment of femoral neck fracture in young and middle-aged patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 75 young and middle-aged patients with femoral neck fracture admitted to the Third Hospital of Hebei Medical University from January 2020 to December 2022, including 44 males and 31 females, aged 34-56 years [(46.1±12.7)years]. According to Garden classification, 26 patients were classified as type II, 35 type III and 14 type IV. According to the Pauwels classification, 9 patients were classified as type I, 31 type II and 35 type III. Forty-nine patients were treated with internal fixation using three cannulated screws alone (cannulated screw group) and 26 with internal fixation using three cannulated screws combined with double-barrel fibular allograft (cannulated screw combined with bone grafting group). The operation time, intraoperative blood loss, length of hospital stay, and quality of fracture reduction were compared between the two groups. At 4, 8 months after operation and at the last follow-up, grading of femoral neck shortening, number of patients walking with crutches, Barthel index, and Harris hip function score were evaluated. The incidence of complications was measured at the last follow-up.Results:All the patients were followed up for 16-37 months [(23.2±4.5)months]. The operation time of the cannulated screw combined with bone grafting group was (86.3±16.1)minutes, longer than (76.9±20.8)minutes of the cannulated screw group ( P<0.05). The intraoperative blood loss was 100.0(50.0, 200.0)ml in the cannulated screw combined with bone grafting group, more than 50.0(50.0, 100.0)ml in the cannulated screw group ( P<0.01). There were no significant differences in the length of hospital stay or the quality of fracture reduction between the two groups ( P>0.05). At 4 months after operation, grading of the femoral neck shortening in the cannulated screw combined with bone grafting group [24 patients (92.3%) with grade 1, 2(7.7%) with grade 2, and 0(0.0%) with grade 3] was better than that in the cannulated screw group [18 patients (36.7%) with grade 1, 28(57.1%) with grade 2, and 3(6.2%) with grade 3] ( P<0.01). At 8 months after operation, grading of femoral neck shortening in the cannulated screw combined with bone grafting group [22 patients (84.6%) with grade 1, 3(11.5%) with grade 2, and 1(3.8%) with grade 3] was better than that in the cannulated screw group [13 patients (26.5%) with grade 1, 27(55.1%) with grade 2, and 9(18.4%) with grade 3] ( P<0.01). At the last follow-up, grading of femoral neck shortening in the cannulated screw combined with bone grafting group [19 patients (73.0%) with grade 1, 5(19.2%) with grade 2, and 2(7.6%) with grade 3] was better than that in the cannulated screw group [8 patients (16.3%) with grade 1, 31(63.2%) with grade 2, and 10(20.4%) with grade 3] ( P<0.01). At 4, 8 months after operation and at the last follow-up, 12(46.2%), 8(30.8%) and 5(19.2%) patients in the cannulated screw combined with bone grafting group and 38(77.6%), 27(55.1%) and 20(40.8%) patients in the cannulated screw group had to walk with crutches, respectively, showing significant difference between the two groups at the other two time points ( P<0.05 or 0.01) except for at the last follow-up ( P>0.05). The Barthel index values were 85.3±3.2, 90.3±4.3, and 95.3±3.9 in the cannulated screw combined with bone grafting group at 4, 8 months after operation and at the last follow-up, significantly higher than 80.8±7.3, 85.4±7.4, and 90.9±7.8 in the cannulated screw group ( P<0.05 or 0.01). The Harris hip scores were (87.0±2.9)points, (92.0±2.9)points and (91.3±2.4)points in the cannulated screw combined with bone grafting group at 4, 8 months after operation and at the last follow-up, significantly higher than (81.0±6.1)points, (85.7±5.8)points, and (89.6±2.0)points in the cannulated screw group ( P<0.01). At the last follow-up, the complication rate was 3.8%(1/26) in the cannulated screw combined with bone grafting group, significantly lower than 22.4%(11/49) in the cannulated screw group ( P<0.05). Conclusion:For femoral neck fractures in young and middle-aged patients, compared with internal fixation using cannulated screw alone, internal fixation using cannulated screw combined with fibular allograft has more advantages in correcting femoral neck shortening, restoring independent living activities and hip joint function, and reducing the incidence of complications despite its longer operation time and more intraoperative blood loss.

Objective:To investigate the effects of methyltransferases like 3(METTL3)mediated m6A modification of double homology cassette A pseudogene8(DUXAP8)on the proliferation,migration and invasion of salivary adenoid cystic carcinoma SACC-LM cells and its potential molecular mechanisms.Methods:Whole-transcriptome sequencing showed that DUXAP8 was highly ex-pressed in SACC than in para-cancerous tissues(P＜0.05).The m6A modification sites on DUXAP8 were predicted using the SRAMP website,and the mRNA and protein expression of m6A-modified genes and the genes associated with the epithelial-mesen-chymal transition(EMT)was measured by qRT-PCR and Western blot,respectively.METTL3 and DUXAP8 was knocked down or overexpressed in SACC-LM cells,and the proliferation,migration,and invasion of the cells were assessed by CCK-8,scratch and Transwell assays.The correlation between METTL3 and DUXAP8 was evaluated using MeRIP-qPCR.Results:The expression of DUXAP8 in SACC tumor was higher than that in para-cancerous tissues(P＜0.05).Knockdown of DUXAP8 reduced proliferation,migration and invasion of SACC-LM cells,as well as the expression of EMT-related genes(P＜0.05).Multiple m6A modification sites of high confidence were found on DUXAP8.METTL3 was highly expressed in tumor tissues,more than other related genes(P＜0.05)and enzyme-encoding genes in SACC-LM cells(P＜0.05).METTL3 was found to function as a methyltransferase to regulate the expression of DUX-AP8,and downregulation of METTL3 inhibited prolifera-tion,migration and invasion of SACC-LM cells and partially reversed the promotion of these activities induced by DUX-AP8 overexpression(P＜0.05).Conclusion:METTL3-me-diated m6A modification upregulated DUXAP8 expression,which promotes the proliferation,migration and invasion of SACC cells.

Objectives:To assess the efficacy of surgical intervention in the management of spinal myeloma(SM)with regards to pain relief,restoration of neurological function,and enhancement of quality of life,as well as to examine the variables influencing the postoperative survival duration of patients.Methods:A retro-spective analysis was conducted on the 49 patients with SM who underwent surgical treatment at the Depart-ment of Orthopaedic Surgery,Zhongshan Hospital,Fudan University and Central Hospital of Xuhui District from January 2010 to December 2022,with complete clinical and follow-up data.Among the patients,there were 28 males and 21 females,with an average age of 64.3±11.3 years,ranging from 36 to 90 years.The average operative time was 148.7±106.4mins,and the average bleeding volume was 792.1±1091.2mL.The fol-low-up time was 1-158 months,with an average of 52.9±37.7 months.There were 4 cases of lesions located alone in the cervical vertebrae,20 cases in the thoracic vertebrae,18 cases in the lumbosacral vertebrae,4 cases in the entire spine,and 8 cases of simultaneous invasion of the thoracic and lumbar vertebrae.There were 24 cases with pain as the main complaint,11 cases with neurological impairment,and 14 cases with concurrent symptoms.Three cases undeiwent anterior surgery and 46 cases undeiwent posterior surgery.The visual analogue scale(VAS)score,Frankel grade of spinal cord injury,and Eastern Cooperative Oncology Group(ECOG)score of patients before and after surgery were compared,and survival analysis of the patients was conducted.Results:The median VAS score and median ECOG score of the patients were 1 and 1 points respectively after surgery,which were significantly lower than before surgery(7 and 2 points respectively,both P＜0.001).The median Frankel grade was E,which was significantly improved compared to preoperative D grade(P＜0.001).One case of spinal implant related complications and two cases of new extraspinal lesions oc-curred after surgery,and no recurrence was observed during follow-up at the surgical site.12 deaths were caused by the progression of myeloma.The 1-year,5-year,and 10-year survival rates of the patients were 89.8％,79.5％,and 75.5％,respectively.Univariate analysis showed that preoperative hemoglobin,blood creati-nine,and postoperative comprehensive treatment were the risk factors affecting patient prognosis(P＜0.1).Cox multiple regression analysis showed that postoperative comprehensive treatment can significantly improve the survival time of patients(P＜0.01).Conclusions:Surgical treatment for SM can effectively alleviate spinal insta-bility,pain and nerve compression symptoms in patients,and significantly improve their qualities of life.Post-operative comprehensive treatments such as chemotherapy,immunotherapy,or targeted therapy are independent influencing factors for improving patient survival.

Objective:To evaluate the efficacy of disposable disinfection cap in preventing catheter-related blood stream infections (CRBSIs).Methods:Literature on the prevention of CRBSIs by disposable disinfection caps were retrieved from CNKI, Wanfang Database, VIP database, Chinese Biomedical Literature Database, PubMed, Cochrane Library, Embase and Web of Science databases. The retrieval period was from the database construction to June 30, 2022. After literature screening, data extraction and quality evaluation were independently carried out by 2 researchers, RevMan5.4 software was used for analysis.Results:A total of 12 articles were included, including 9 832 patients. Meta-analysis results showed that compared with conventional manual disinfection, disposable disinfection cap could reduce the incidence of CRBSIs, and the difference was statistically significant ( RR = 0.58, 95% CI 0.43-0.79, P<0.01). Disposable disinfection cap could reduce the incidence of CRBSIs in adults, but there was no significant difference in the incidence of CRBSIs in children ( P>0.05). It could reduce the incidence of CRBSIs in patients with indwelling vascular catheters in ICU ( RR = 0.58, 95% CI 0.38-0.89, P<0.05), but there was no statistical difference in the incidence of CRBSIs in patients without indwelling vascular catheters in ICU ( P>0.05). In addition, the compliance of the use of disinfection caps by nursing staff was improved by 80% - 90% and the treatment cost was saved by about 282 - 464 dollars. Conclusions:Disposable disinfection caps can reduce the occurrence of CRBSIs, improve the disinfection compliance of nursing staff, and save the hospitalization cost of patients. It is suggested to be popularized in clinical practice.

ObjectiveTo investigate the satisfaction of both service providers and users in community health service centers through questionnaires， and to analyze the reasons， so as to put forward suggestions for improving satisfaction. MethodsSampling was conducted in 247 community health service centers in 16 districts of Shanghai， and data were collected from employees and patients through on-site questionnaires. ResultsA total of 10 334 eligible questionnaires were collected from community health service centers， of which 7 712 were from patients and 2 622 were from employees. In 2021， the public's satisfaction with community health service centers was 96.51 points， and the satisfaction of employees was 94.08 points. The public expressed lower satisfaction with the availability of essential drugs for outpatient services， while the staff were less satisfied with their salary and benefits， work recognition， and career development. Regarding family doctor services， 73.38% of the public had signed up for family doctor services， while 23.57% of the public did not know about the family doctor services， and 16.18% believed it was necessary to improve the publicity of basic public health services. ConclusionThe public's overall satisfaction with the service of community health services is gradually increased. The basic medical services of community health are recognized by residents. Drug allocation needs to be improved urgently， and publicity and promotion need to be further strengthened. The overall satisfaction of employees is high， but further improvement is needed in terms of salary and benefits， work recognition， and career development.

Objective:To investigate the current situation of expected sadness of family caregivers of first stroke patients and analyze its influencing factors, so as to provide reference for the formulation of psychological decompression intervention program for family caregivers of stroke patients.Methods:Convenience sampling method was used to conduct cross-sectional survey of 212 family caregivers of first stroke patients who were hospitalized in the First Affiliated Hospital of Shandong First Medical University from March 2020 to May 2021, using general information questionnaires and Anticipatory Grief Scale and Connor-Davidson Resilience Scale to investigate and anlalyzed its influencing factors.Results:The scare of anticipatory grief of the caregivers of first stroke patients was 87.93 ± 17.36. The results of multiple stepwise regression analysis showed that the age of family caregivers, psychological elasticity, the degree of relationship with patients, patients′ cognitive ability and self-care ability were the influencing factors of anticipatory grief of family caregivers of first stroke patients ( t values were -6.73 -11.77, P <0.05). Conclusions:The caregivers of first stroke patients have serious anticipatory grief. Staff should pay attention to the psychological conditions of the family caregivers and take effective measures to promote their physical and mental health.
