BACKGROUND:Stand-alone oblique lateral interbody fusion has a high rate of complications of fusion segment sink.Oblique lateral interbody fusion with posterior fixation can provide stable support,but intraoperative position changes and double incisions weaken the advantages of this technique.Oblique lateral interbody fusion combined with lateral plate fixation can achieve one-stage decompression in the same incision,while the lateral internal fixation provides stable support. OBJECTIVE:To analyze the short-term efficacy of oblique lateral interbody fusion combined with lateral plate fixation in the treatment of single-level lumbar degenerative disease. METHODS:The clinical data of 34 patients with single-level lumbar degenerative disease treated with oblique lateral interbody fusion combined with lateral plate fixation were collected from May 2020 to October 2022.Among them,14 were males and 20 were females aged from 41 to 72 years at the mean age of(58.6±9.9)years.There were 11 cases of lumbar spondylolisthesis(Ⅰ°),7 cases of lumbar disc herniation with segmental instability,and 16 cases of lumbar spinal stenosis.Operation time,blood loss,and complications were recorded.Visual analog scale scores of lumbago,radiative pain of both lower limbs,and Oswestry disability index scores were evaluated before surgery,3 months after surgery,and the last follow-up.Dural sac cross-sectional area,intervertebral height,and intervertebral fusion were measured and observed. RESULTS AND CONCLUSION:(1)The 34 patients were followed up for 14-36 months,with an average of(21.3±5.2)months.(2)The operation time ranged from 50 to 92 minutes,with an average of(68.5±11.1)minutes.Intraoperative blood loss was 50-170 mL,with an average of(71.6±25.3)mL.(3)Compared with the preoperative results,the visual analog scale scores and Oswestry disability index scores were significantly decreased at 3 months after surgery and at the last follow-up(P<0.001),and the maximum Oswestry disability index scores were improved by nearly 50％.(4)Bone fusion was achieved in all patients during half-year follow-up.The overall complication rate was 21％(7/34),including 1 case of plate displacement,3 cases of cage subsidence,1 case of psoas weakness,and 2 cases of anterior thigh pain.(5)It is concluded that oblique lateral interbody fusion combined with lateral plate fixation for the treatment of lumbar degenerative diseases has the characteristics of less blood loss,short operation time,rapid postoperative recovery,and significant short-term clinical efficacy with the stable support to a certain extent.The long-term curative effect needs further follow-up observation.

Objective To analyze the influence of drainage volume on prognosis of acute hydrocephalus(AHC)after aneurysmal subarachnoid hemorrhage(aSAH)by continuous lumbar drainage.Methods A retrospective trial was conducted on 82 AHC patients after aSAH admitted to the First Affiliated Hospital of Chongqing Medical University between January 2017 and January 2022.In 6 months after discharge,modified Rankin Scale(mRS)score was used to evaluate the prognostic outcomes.Univariate and multivariate logistic regression analyses were performed on demographic factors,severity of subarachnoid hemorrhage(SAH)at admission,medical history,cerebral vasospasm,and lumbar drainage data.Then a nomogram prediction model was constructed.Results Univariate analysis found that World Federation of Neurosurgical Societies(WFNS)score,Hunt-Hess grade,modified Fisher grade,time for continuous lumbar drainage,shunt dependence,cerebral vasospasm,and drainage volume were factors affecting the prognosis of the patients.Then logistic regression analysis revealed that high WFNS score(OR:3.25,95％CI:1.11～9.48),high modified Fisher grade(OR:3.66,95％CI:1.08～12.35),shunt dependence(OR:15.56,95％CI:1.22～198.57),and cerebral vasospasm(OR:22.24,95％CI:3.08～160.68)were independent predictors for mRS score,while volume of continuous lumbar drainage(OR:0.57,95％CI:0.40～0.82)was an independent protective factor.ROC curve analysis indicated a good predictive performance of the model(AUC=0.898,95％CI:0.935～0.861).Internal validation through Bootstrap method demonstrated excellent discriminatory ability of the model(C-index=0.950,95％CI:0.904～0.996;adjusted C-index:0.934).Conclusion Increased volume of lumbar drainage is an independent protective factor for poor prognosis following aSAH and can improve the prognosis of SAH patients.

Tuberous sclerosis complex(TSC)is a rare genetic disease that can lead to benign dysplasia in multiple organs such as the skin, brain, eyes, oral cavity, heart, lungs, kidneys, liver, and bones. Its main symptoms include epilepsy, intellectual disabilities, skin depigmentation, and facial angiofibromas, whilst incidence is approximately 1 in 10 000 to 1 in 6000 newborns. This case presents a middle-aged woman who initially manifested with epilepsy and nodular depigmentation. Later, she developed a lower abdominal mass, elevated creatinine, and severe anemia. Based on clinical features and whole exome sequencing, the primary diagnosis was confirmed as TSC. Laboratory and imaging examinations revealed that the lower abdominal mass originated from the uterus. CT-guided biopsy pathology and surgical pathology suggested a combination of leiomyoma and abscess. With the involvement of multiple organs and various complications beyond the main diagnosis, the diagnostic and therapeutic process for this patient highlights the importance of rigorous clinical thinking and multidisciplinary collaboration in the diagnosis and treatment of rare and challenging diseases.

Objective To establish a recurrence risk prediction model for meningioma based on HOXA9 DNA methylation.Methods Meningioma-related datasets were downloaded from GEO database for screening homeobox genes(HOXs)with prognostic values using differential methylation and ROC curve analysis and Cox regression analysis.The differentially methylated CpG sites with high predictive efficacy were selected to establish the risk prediction model using Lasso-Cox regression analysis,based on which the patients were divided into high-and low-risk groups by the cutoff value.The methylation levels of CpG sites were verified at the cell and tissue levels using methylation-specific PCR(MS-PCR).Clinical meningioma tissue samples were used to validate the predictive efficacy of the model.Results HOXA9 methylation level was significantly up-regulated in meningiomas(P<0.001)and showed a high diagnostic efficiency(AUC=0.884)as an independent risk factor for overall survival(P<0.01)positively correlated with the degree of malignancy and poor prognosis of meningioma(P<0.05).Risk stratification by HOXA9 methylation was more accurate than WHO grading for predicting recurrence and patient survival time.The AUCs of the sites cg03217995 and cg21001184 were both above 0.8 for meningioma diagnosis and above 0.6 for predicting recurrence.The patients'clinical characteristics differed significantly between the high-and low-risk groups(P<0.001),and the prediction score of the model was an independent prognostic factor for meningioma(P<0.05).MS-PCR results showed that the methylation levels of the two sites increased significantly in meningioma cells.In clinical samples,the combined model showed a high prediction efficiency(AUC=0.857),and the predicted risk of progression was highly consistent with the patients'actual condition.Conclusion High HOXA9 methylation level is a predictor for poor prognosis of meningiomas,and the combined prediction model based on its CpG sites provides a new approach to early screening of meningioma patients at risk of progression.

Objective:To investigate the effect of the number of positive preoperative serological tumor markers on the surgical approach and prognosis of patients with intrahepatic cholangiocarcinoma.Methods:This is a retrospective case-series study. Data from 548 patients with intrahepatic cholangiocarcinoma after radical resection from October 2010 to April 2019 were retrospectively collected in 10 hospitals of China. There were 277 males and 271 females with an age of (57.8±10.2)years(range:23 to 84 years). Four hundred and twenty-six patients(77.7%) had at least one positive preoperative serum tumor marker. The data collection included the results of 4 preoperative serological tumor markers,other preoperative indicators(5 prodromal symptoms, 6 medical history,8 preoperative serological indicators,5 preoperative imaging indicators,and 14 preoperative pathological examination indicators),baseline data (gender and age),surgical methods,and prognostic follow-up data. Four preoperative results of serologic tumor marker and surgical procedure were converted into categorical variables. The number of positive preoperative serum tumor markers was used as the treatment variable,the surgical method was used as the mediating variable,and the survival time was used as the outcome variable. Univariate and multivariate analysis were used to screen for other preoperative indicators which were independent factors that influenced the surgical procedure and the prognosis of patients as covariates to analyze the mediating effect.Results:Of the 548 patients included in the study, 176 patients (32.1%) underwent partial hepatectomy,151 patients(27.5%) underwent hemihepatectomy, and 221 patients(40.3%) underwent partial hepatectomy or hemihepatectomy combined with other treatments. The results of the univariate and multivariate analysis showed that the number of positive serum tumor markers,intrahepatic bile duct dilatation,portal vein invasion,pathological differentiation,pathological type,vascular invasion,T stage,N stage and maximum tumor diameter were independent factors influencing the surgical procedure(all P<0.05). Intrahepatic bile duct dilatation,pathological differentiation and T stage were independent prognostic factors for patients with intrahepatic cholangiocarcinoma(all P<0.05). Intrahepatic bile duct dilatation,differentiation and T stage were included as covariates in the mediation effect model. The results showed that the number of positive serum tumor markers before surgery had a negative predictive effect on the survival time of patients with intrahepatic cholangiocarcinoma ( β=-0.092, P=0.039),and had a positive predictive effect on the surgical method ( β=0.244, P<0.01). The number of positive serum tumor markers had a negative predictive effect on the survival time of patients with intrahepatic cholangiocarcinoma ( β=-0.151, P=0.002). Direct and indirect effects accounted for 71.3% and 28.7% of total effects,respectively. Conclusions:The higher the positive number of preoperative tumor markers,the worse the prognosis of patients with intrahepatic cholangiocarcinoma. The number of positive cells not only directly affects the prognosis of patients,but also indirectly affects the prognosis of patients by affecting the surgical method.

This study details a rare instance of a high fibula fracture, classified as a Bosworth fracture. A 54-year-old male presented with pain and restricted movement in his right ankle after a sprain that occurred 10 hours ago. After initial assessments he was diagnosed as a right ankle fracture with posterior dislocation, a proximal right fibula fracture, and an injury to the right lower tibiofibular joint. According to Lauge-Hansen classification this was a type IV injury charactered by pronation-external rotation. Attempts at manual reduction were unsuccessful. Further evaluation using CT scans with three-dimensional reconstruction showed a separation and dislocation at the lower tibiofibular joint, with the distal fibula interlocked with the posterolateral tibia. Additionally, comminuted fractures of the medial and posterior malleoli showed significant displacement and misalignment, leading to persistent ankle dislocation. Immediate calcaneal traction and symptomatic treatment were applied. On the third day of admission a reevaluation indicated successful reduction of the dislocated ankle and tibiofibular joint. Surgery was then performed with favorable outcome. Follow-up X-rays at one and a half years after surgery demonstrated bony heal of the fractures with normal ankle joint space and functionality. Bosworth fractures involving pronation-external rotation are notably less common than those with posterior-external rotation. When manual reduction proves ineffective, applying continuous calcaneal traction with gradual tension can help unlock fibular dislocation, thereby expediting surgical intervention.

Objective:To investigate the satisfaction levels of the rural elderly in Dafeng district of Yancheng, Jiangsu province with the contracted family doctor services, and to identify the factors that influence their satisfaction.The findings of this study will provide valuable insights for improving the quality of the contracted family doctor services offered to the rural elderly population.Methods:The study utilized the stratified cluster sampling method to select elderly individuals aged 60 years and above from Dafeng district, Yancheng city for a questionnaire survey.Specifically, the study focused on elderly individuals who had participated in contracted family doctor services for more than six months.The survey aimed to gather information on the elderly population's general situation, as well as their understanding, utilization, and satisfaction with contracted family doctor services.The satisfaction of contracted family doctor services was analyzed using the chi square test and multivariate Logistic regression to identify the influencing factors.Results:The study surveyed 385 elderly individuals from rural areas who had contracted family doctor services.The results showed that 88.3%(340/385)of respondents were satisfied with the services they received.Additionally, 99.2%(382/385)of those surveyed were aware of the contracted family doctor services, and 81.8%(315/385)had received basic medical services from their signed-up doctors.The results of a multifactor analysis that examined the factors influencing the overall satisfaction of elderly patients with their contracted family doctor services revealed several significant factors.Specifically, being female( OR=2.557, 95% CI: 1.122-5.830, P=0.026)and unmarried( OR=7.355, 95% CI: 1.850-29.237, P=0.005), supporting the contracted family doctor services system( OR=18.442, 95% CI: 1.732-195.973, P=0.016), believing that the contracted medical institutions had excellent hardware facilities( OR=9.918, 95% CI: 2.313-42.526, P=0.002)and providing high-quality health services for the elderly( OR=8.723, 95% CI: 1.556-48.908, P=0.014), as well as experiencing improved health status after signing the contract( OR=5.006, 95% CI: 1.764-14.201, P=0.002)were all significant factors influencing their satisfaction.These findings suggest that these factors are important considerations for improving the satisfaction of elderly patients with their contracted family doctor services. Conclusions:The contracted family doctor services provided in Dafeng district, Yancheng city have been well received by the rural elderly population.Factors such as gender, marital status, attitude towards the contracted family doctor services system, improvements in health status after contracting the service, quality of the hardware facilities at the contracted medical institution, and availability of health services specifically tailored for the elderly all play a role in determining the level of satisfaction among the contracted elderly population.To better serve the elderly population, it is crucial that we prioritize their needs.This can be achieved by improving the level of "suitable aging" in the contracted services and enhancing the satisfaction of family doctors who provide these services.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.
