ObjectiveTo investigate the recurrence of ischemic stroke (IS) and to analyze the association between four indices of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) and the risk of IS recurrence by analyzing the follow-up data related to IS in the community-based natural population of Songjiang District, Shanghai, so as to provide a scientific basis for improving the prognosis of stroke patients in the community and controlling IS recurrence. MethodsA prospective follow-up study was conducted among the IS patients in the community-based cohort population, collecting data about patient’s age, gender, disease history, biochemical indicators, and etc. Cox regression model and restricted cubic spline model were used to analyze the relationship between different levels of plasma lipids and the recurrence of IS in these patients. ResultsA total of 1 368 patients with IS were included. The total follow-up duration was 7 171.46 person-years, with a median follow-up time of 6.24 years. There were 420 cases of IS recurrence, resulting in a cumulative recurrence rate of 30.70%. The results of multivariate Cox regression analysis showed that the recurrence risk of IS was reduced when the baseline TC and LDL-C levels of IS patients were in the ranges of 4.65‒5.67 mmol·L^-1 and 2.52‒3.46 mmol·L^-1, respectively. The results of restricted cubic spline analysis showed a U-shaped relationship between baseline TC and LDL-C levels and the recurrence risk in IS patients. ConclusionThe cumulative recurrence rate of patients with IS in the community of Songjiang District in Shanghai is high, and the levels of TC and LDL-C at baseline survey are correlated with the recurrence of IS in these patients. It is suggested to pay more attention to the levels of LDL-C and TC in patients with IS, so as to improve the prognosis.

OBJECTIVE: To explore the pain-location interaction between pressure-sensitive points on the body surface and traditional acupoints in patients with chronic non-specific low back pain (CNLBP) under different disease courses, using Euclidean distance and multivariate statistical analysis. METHODS: A pressure-sensitive point detection was performed on 30 CNLBP patients with varying disease courses. A constant pressure was applied using an FDK20 algometer within a designated lumbar area, a total of 50 points were tested, and the tested points were numbered; the visual analogue scale (VAS) pain score was recorded simultaneously. MatlabR2022a9.12. software was used to extract the positions of pressure-sensitive points, and preprocessing and normalization of point location and VAS scores data were conducted. Under constraint conditions (VAS≥8.0 ∩ Euclidean distance to acupoint≤0.5), the proportion of pressure-sensitive points within the Euclidean distance threshold to each acupoint (PVD_acupoint) was calculated, followed by multivariate statistical analysis. RESULTS: ①Constrained analysis of PVD_acupoint showed that PVD_{Qihaishu (BL24)} and PVD_{Dachangshu (BL25)} were positively correlated with disease course (r=0.55, P<0.01). ②Factor analysis and silhouette analysis revealed that PVD_{Shenshu (BL23)} and PVD_{Dachangshu (BL25)} exhibited trends consistent with disease course progression (P>0.05), with different degree (P<0.01). CONCLUSION The PVD_acupoint value based on Euclidean distance can characterize the pressure sensitivity features of traditional acupoints associated with disease. Multivariate statistical analysis of PVD_acupoint confirms that selecting the acupoint combination of Shenshu (BL23) and Dachangshu (BL25) for CNLBP is associated with the distribution of surrounding pressure-sensitive points and the pathological characteristics of the condition.

Objectives:To investigate the early related factors for hepatic insufficiency after hemihepatectomy and to construct and validate a nomogram model.Methods:This is a retrospective cohort study.There were 207 patients with liver tumor who underwent hemihepatectomy in the Department of Hepatobiliary Surgery, Cancer Hospital, Chinese Academy of Medical Sciences from October 2016 to December 2022. Using the random number method, patients were randomly divided into a model group( n=166) and a validation group( n=41) according to an 4∶1 ratio. There were 118 males and 48 females in the modeling group,with an age ( M(IQR)) of 59.0(13.3) years (range: 22.0 to 81.0 years),42 patients in the group with postoperative liver insufficiency and 124 patients in the group without postoperative liver insufficiency. There were 32 males and 9 females in the validation group, with an age of 54.0(19.0) years (range: 25.0 to 81.0 years). The first results of the peripheral blood test of patients within 24 hours after surgery were collected,and the independent related factors for incomplete postoperative liver function were determined by multivariate Logistic regression analysis,and related factors of postoperative incomplete liver function were screened by best subset selection. A nomogram model of the related factors of postoperative hepatic insufficiency after hemihepatectomy was constructed using R software,validated by internal and external validation of the model. Results:Multivariate logistic regression analysis showed that elevated D-dimer level and decreased antithrombin Ⅲ (AT-Ⅲ) activity within 24 hours after surgery were independent related factors for the development of postoperative hepatic insufficiency in hemihepatectomized patients. The results of the best subset selection showed that ALT, D-dimer, and AT-Ⅲ activity levels within 24 hours postoperatively were the most relevant factors for postoperative hepatic insufficiency. The R software was applied to build a nomogram prediction model based on the above three indicators in the model set, and the receiver operating characteristic(ROC) curve of the model showed an area under the curve of 0.803 and the calibration curve showed a U-index of -0.012 for the model( P=0.977). The results of the clinical decision analysis and the clinical impact curve indicated that the model had good clinical utility. The internal validation results of the Bootstrap method suggested that the model had reasonable consistency. The area under the ROC curve of the validation group model was 0.806, suggesting that the model had a good generalization prediction ability. Conclusions:The levels of ALT, D-dimer, and AT-Ⅲ activity within 24 hours after hemihepatectomy are valuable indicators for predicting liver insufficiency after hemihepatectomy. The nomogram model is reliable and can be used as an indicator for close postoperative monitoring.

Objective:To explore the incidence of chronic obstructive pulmonary disease (COPD) in a cohort aged 40 years and above in Songjiang District, Shanghai, and to analyze the association of Mediterranean diet pattern and dietary approaches in stopping hypertension pattern (DASH) with the risk of developing COPD.Methods:Based on a natural population cohort in Songjiang District, Shanghai, 27 474 adults aged 40 years and above who did not have COPD at baseline were enrolled in the study. The Cox proportional risk regression model was used to analyze the association of baseline Mediterranean diet pattern score and DASH score with the risk of COPD, and the hazard ratio ( HR) of the risk and its 95% CI were calculated. Restricted cubic spline was used to analyze the nonlinear association between the two diet scores and the risk of COPD. Stratified analyses were performed according to gender, age, smoking status, etcetera. Sensitivity analyses were conducted by censoring cases diagnosed within one year after the baseline survey or people with a history of malignant tumor disease. Results:As of June 30, 2023, after a median follow-up time of 6.21 years, there were 1 089 (4.0%) new COPD cases with an incidence density of 64.00 per 10 000 person-years. After adjusting for relevant confounders, in the Mediterranean tertile subgroups under diet pattern score, the risk of developing COPD could be reduced by approximately 14% in the intermediate scoring group ( HR=0.86, 95% CI: 0.75-0.99) and 15% in the highest scoring group ( HR=0.85, 95% CI: 0.72-0.99) compared to the lowest scoring group. The association remained after censoring cases diagnosed within one year of the baseline survey ( HR=0.82, 95% CI: 0.70-0.95; HR=0.82, 95% CI: 0.68-0.97) or censoring people with a history of malignant tumor disease ( HR=0.84, 95% CI: 0.73-0.97; HR=0.84, 95% CI: 0.71-0.99). No statistical association was found between the DASH score and the risk of COPD. Conclusions:The Mediterranean diet pattern was associated with a lower risk of COPD. Increasing the intake of vegetables, fruits, legumes, and whole grains and decreasing the intake of red meat and others can reduce the risk of COPD. No association was found between the DASH dietary pattern and the risk of COPD in this community population.

BACKGROUND:Bone transport has been used for a variety of reasons in bone defects with good clinical results.However,various complications have also attracted the attention of practitioners and the avoidance of non-healing of the docking point has become a common concern for doctors and patients. OBJECTIVE:To explore effective methods of avoiding non-healing of the docking point in the treatment of tibial bone defects by bone transport so as to shorten the treatment period and reduce the pain of patients. METHODS:The clinical data of 21 patients with unilateral tibial bone defect admitted to the No.910 Hospital of Joint Logistics Support Force of Chinese PLA from January 2018 to January 2021 were retrospectively analyzed,including 16 males and 5 females,aged(32.8±10.3)years,with an average bone defect length of 10.2 cm.All 21 patients received bone transport surgery,during which the bone defect area was filled with bone cement to reduce the adverse factors affecting the healing of the docking point.The Association for the Study and Application of the Methods of Ilizarov,healing index and incidence of adverse reactions were evaluated during postoperative follow-up. RESULTS AND CONCLUSION:The 21 patients were followed up for 15 to 24 months after surgery,and the extended area was all well mineralized and had no malformations,and no refractures occurred during treatment.Among them,one patient had foot drop,which could not be completely corrected after surgical release of the Achilles tendon and wearing foot and ankle orthotics.19 patients had different degrees of needle tract infection,and no deep infection occurred after timely needle tract nursing.The healing rate of the docking point was 100%;the healing index was 36-45 d/cm and the average was 38 d/cm.The Association for the Study and Application of the Methods of Ilizarov showed that bone healing was excellent in 17 cases(81%)and poor in 4 cases(19%).The results of limb function were excellent in 18 cases(86%)and good in 3 cases(14%).These findings show that bone cement segmental filling during bone transport is an effective method to solve the non-healing of the docking point,shorten the patient's treatment period and reduce the patient's pain.

Objective To analyze the survival status of inpatients with cervical cancer registered in Nantong admitted in Nantong Cancer Hospital from 2002 to 2017. Methods Inpatients with cervical cancer in Nantong Cancer Hospital were followed up from 2017 until December 31, 2020 using active and passive methods to determine their survival outcome. The rate of follow-up loss was statistically analyzed by Chi-square test, the observed survival rate for each year was calculated using the life table, the survival curve was drawn with R language, and the survival rates of patients in different age groups and from different regions were compared with log-rank test (Mantel-Cox). Results A total of 5645 cervical cancer cases were registered. Among them, the survival outcome was recorded for 5512 cases. The success rate of follow-up was 97.64%, and the loss of follow-up rate was 2.36%. The average age of onset was 56.67±12.78 years. The median survival time was 6.54 years, and the 1-, 3-, 5-, and 10-year observed survival rates were 91.50%, 76.95%, 60.99%, and 28.51%, respectively. Among the age groups, significant differences in survival rate were observed between the 15- and 60-year-old groups (χ²=7.469, P=0.006) and between the 15- and 80-year-old groups (χ²=36.317, P < 0.001). No significant difference in survival rate was found between patients from Haimen and Qidong (χ²=2.779, P=0.095) and between patients from Qidong and Tongzhou (χ²=0.515, P=0.473). Significant difference in survival rate was observed among other regions (P < 0.05). Conclusion In this study group, the survival rates of hospital-based patients with cervical cancer significantly differ among the age groups and regions of origin and significantly decreased with age. The high follow-up rate fully reflects the comprehensive effect of the treatment in Nantong Cancer Hospital for registered patients with cervical cancer in Nantong.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective To compare the analgesic effect, duration and incidence of adverse reactions of liposome bupivacaine (LB) and bupivacaine hydrochloride after intercostal nerve block in single-port thoracoscopic lung surgery. Methods In Department of Thoracic Surgery of the First Affiliated Hospital of Xinxiang Medical University between September 2023 and March 2024, 228 patients who needed to undergo thoracoscopic lung surgery were selected and divided into two groups by random number table method: a group B with bupivacaine hydrochloride (n=118), and a group LB with LB (n=110). Intraoperative intercostal nerve block was performed under endoscopy, and the time of first use of analgesic drugs after surgery, cumulative use of opioids 72 h after surgery, incidence of postoperative nausea and vomiting, length of stay and other indicators were evaluated and recorded. Results Visual analogue scale (VAS) scores at 4 h, 8 h, 12 h, 24 h, 48 h and 72 h in the LB group were significantly lower than those in the group B (P<0.05). The total number of activities within 48 h after surgery in the group B was significantly lower than that in the LB group (P<0.05), and the postoperative hospitalization stay in the LB group was shorter than that in the group B, but the difference was not statistically significant. There was no statistical difference between the two groups in postoperative adverse reactions. Conclusion Intercostal nerve block with LB during single-port thoracoscopic lung surgery can significantly reduce postoperative pain, improve quality of life, and promote recovery of the patients. It is worthy of clinical application.
