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.

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 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.

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.

Objective:To investigate the effects of combined spinal-epidural anesthesia (CSEA) on postoperative pain and short-term cognitive function in elderly patients undergoing hip fracture surgery.Methods:A total of 60 elderly patients undergoing hip fracture surgery in Dongchangfu District of Liaocheng People′s Hospital from October 2018 to September 2020 were selected as subjects and they were divided into the control group and the observation group by performed different anaesthesias methods, with 30 patients in each group. The control group underwent total intravenous anesthesia (TIVA), and the observation group underwent CSEA. The scores of visual analogue scale (VAS) at different points and the analgesic recovery rate within 48 h of the two groups were compared, and mini mental state evaluation (MMSE) scores of two groups at different points were evaluated. The levels of serum interleukin (IL)-6, IL-10 and tumor necrosis factor-α (TNF-α) of the two groups before the surgery and on the 1 d after the surgery were compared, and adverse events after the surgery were observed.Results:The analgesic recovery rate within 48 h in the observation group was lower than that in the control group: 3.33%(1/30) vs. 26.67%(8/30), the difference was statistically significant ( χ2 = 6.40, P<0.05). The VAS scores at 4, 6, 12, 24, 48 h after the surgery in the observation group were lower than those in the control group ( P<0.05). The scores of MMSE at 1 and 3 d after the surgery in the observation group were higher than those in the control group: (25.38 ± 2.86) scores vs. (22.17 ± 2.72) scores, (26.89 ± 3.04) scores vs. (25.17 ± 2.69) scores, the differences were statistically significant ( P<0.05). At 1 d after the surgery, the levels of IL-6, TNF-α in the observation group were lower than those in the control group: (67.59 ± 15.47) ng/L vs. (86.75 ± 17.88) ng/L, (18.75 ± 4.23) ng/L vs. (22.81 ± 4.30) ng/L; and the level of IL-10 was higher than that in the control group: (39.78 ± 8.31) ng/L vs. (34.76 ± 7.54) ng/L, the differences were statistically significant ( P<0.05). There was no statistical difference in the total incidence of postoperative adverse events between the two groups ( P>0.05). Conclusions:CSEA can effectively relieve postoperative pain, improve short-term cognitive function, reduce inflammatory response in elderly patients with hip fracture surgery, and with great safety.

ObjectiveBased on a demand survey， to put forward the idea of family doctor service health service packages for people in functional communities， and provide suggestions for the implementation of family doctor health service in such communities. MethodsThrough the stratified cluster sampling survey of a science and innovation bearing functional community， combined with literature research， current situation survey， case analysis and interviews， this paper proposes the service content of the service packages. ResultsOn the basis of demand survey， the mode of "specified action + optional action" should be adopted. Community health service center should first provide basic service， and then expand their services in diagnosis， treatment， and health management in line with local demand， and provide optional multi-level health service packages for scientific and innovative functional community residents， which should be divided into basic health service， value-added health service and high-end health service. ConclusionSorting out the content of health service packages of family doctor service in functional communities can provide the basis for further improving the allocation of medical service resources， further optimizing the design of the financing and compensation mechanism， and further standardizing the contract service of family doctors.
