Objective:Based on a single-center retrospective study,to explore the efficacy of intervertebral fusion through different approaches combined with pedicle screw internal fixation in the treatment of single-segment low-grade lumbar spondylolisthesis.Methods:This study retrospectively analyzed the clinical data of 87 patients with single-segment low-grade lumbar spondylolisthesis who were treated in our hospital from January 2021 to August 2022,the cases were divided into Group A(41 cases)and Group B(46 cases)according to the differences in surgical methods.Group A received treatment with posterior lumbar interbody fusion(PLIF)combined with pedicle screw internal fixation,while Group B received treatment with percutaneous endoscopic posterior lumbar interbody fusion(PE-PLIF)combined with pedicle screw internal fixation.Both groups were followed up for two years.The Visual Analogue Scale(VAS)scores of the waist and legs,perioperative indicators,recovery of lumbar function[Japanese Orthopaedic Association(JOA)score,Oswestry Disability Index(ODI)score],and serum inflammatory mediators levels[interleukin-1α(IL-1α),transforming growth factor β1(TGF-β1),interleukin-6(IL-6)],the rate of lumbar interbody fusion,the rate of lumbar spondylolisthesis and the incidence of postoperative complications of the two groups were compared.Results:The operation time and the number of intraoperative X-ray fluoroscopy sessions in group B were both more than those in group A,while the hospital stay,the intraoperative blood loss and total incision length in Group B were all shorter than those in group A(P＜0.05).The VAS scores of the waist and legs in both groups decreased at 3 d after operation and the last follow-up(P＜0.05),and the VAS scores of the waist and legs in group B were lower than those in group A(P＜0.05).The ODI scores of both groups decreased at 3 d after operation and the last follow-up,and the ODI scores of group B were lower than those in group A;The JOA score increased,and the JOA scores of group B were all higher than those in group A(P＜0.05).Serum IL-1α,TGF-β1 and IL-6 levels in both groups decreased at 3 d and 7 d after operation,and serum IL-1α,TGF-β1 and IL-6 levels in group B were all lower than those in group A(P＜0.05).There was no statistically significant difference in the incidence of complications,the rate of lumbar interbody fusion,and the rate of lumbar spondylolisthesis between the two groups(P＞0.05).Conclusion:Compared with PLIF,PE-PLIF combined with pedicle screw internal fixation in the treatment of single-segment low-grade lumbar.spondylolisthesis,can better relieve the degree of pain of the waist and legs,improve lumbar dysfunction,regulate serum inflammatory mediators levels more effectively,and has higher safety and significant therapeutic efficacy.

Objective:To analyze overall survival (OS), influential factors, and causes of death in patients with newly diagnosed non-transplant multiple myeloma (NDMM) at grassroots hospitals.Methods:The clinical data of 56 patients with NDMM admitted to the Department of Hematology, Wuwei People's Hospital from January 2018 to October 2022 were retrospectively analyzed. Using the Kaplan-Meier and Cox regression survival analysis models, univariate and multivariate analyses were performed to evaluate the factors affecting the OS of patients with NDMM.Results:The median OS of patients with NDMM was 27 months. Univariate analysis indicated that whether or not to receive chemotherapy was a risk factor affecting OS. Multivariate analysis revealed that age ( HR: 2.215, 95% CI 1.056-4.648, P < 0.05), renal dysfunction ( HR: 3.482, 95% CI 1.359-8.923, P < 0.05), and whether or not to receive chemotherapy ( HR: 0.83, 95% CI 0.021-0.331, P < 0.001) were all significant risk factors affecting OS (all P < 0.05). Conclusions:The median survival time of patients with NDMM is short. Age, renal dysfunction, and not receiving chemotherapy are unfavorable factors affecting OS. Pulmonary infection, renal failure, and disease progression are the main causes of death in patients with NDMM.

Objective To investigate the risk factors of overt hepatic encephalopathy(OHE)and death in cirrhotic portal hyperten-sion patients after transjugular intrahepatic portosystemic shunt(TIPS).Methods A retrospective selection was conducted on 40 patients with cirrhotic portal hypertension who underwent TIPS.The follow-up time was 3-41 months,median follow-up time was 20.36 months.The postoperative hepatic encephalopathy(HE)were divided into OHE group(20 cases)and non-OHE group(20 cases)and were further divided into death group(11 cases)and survival group(29 cases)according to their postoperative survival status.Gender,age,preoperative height,weight,total bilirubin,albumin,alanine aminotransferase,aspartate aminotransferase,creatinine,international normalized ratio(INR),prothrombin time,blood glucose,white blood cells,hemoglobin and platelet of all patients were recorded in detail,as well as whether they had diabetes and portal thrombosis before surgery.Child score and model for end-stage liver disease(MELD)score were also performed.The related risk factors of HE and death were obtained by statistical analysis of the two groups.Results The incidence rate of OHE after TIPS was 50%.The analysis revealed that age[hazard ratio(HR)1.115,95%confidence interval(CI)1.007-1.234,P=0.036]and albumin(HR 0.776,95%CI 0.627-0.960,P=0.020)were independent risk factors for OHE after TIPS.The receiver operating characteristic(ROC)curves were drawn with area under the curve(AUC)of 0.733 for age and AUC of 0.784 for albumin.The mortality rate after TIPS was 27.5%,and the analysis indicated that albumin(HR 0.660,95%CI 0.453-0.961,P=0.030),creatinine(HR 1.031,95%CI 1.001-1.062,P=0.044),and aspartate aminotransferase(HR 1.074,95%CI 1.013-1.139,P=0.018)were independent risk factors for death after TIPS.The ROC curves were drawn with AUC of 0.716 for albumin,AUC of 0.762 for creatinine,and AUC of 0.710 for aspartate aminotransferase.Conclusion Postoperative OHE is posi-tively correlated with age and negatively correlated with albumin.Furthermore,the risk of postoperative death is positively correlated with creatinine and aspartate aminotransferase and negatively correlated with albumin.

Objective:To evaluate the effectiveness of yttrium aluminum garnet (Nd∶YAG) laser vitreolysis in the treatment of symptomatic vitreous opacity.Methods:An observational case series study was performed.Forty-four eyes of 44 patients diagnosed as physiological vitreous opacity in Shenzhen Eye Hospital from June 2021 to September 2022 and treated with Nd∶YAG laser vitreolysis were enrolled.Before treatment and 2 months after last treatment, best corrected visual acuity (BCVA) evaluated with standard logarithmic visual acuity chart, floater areas calculated through infrared fundus photography, and objective scattering index (OSI) obtained by the Optical Quality Analysis System (OQAS) were recorded.The occurrence of complications during the follow-up period was recorded.The differences in each indicator were compared, and a simple linear regression model was used to analyze the relationship between floater area and OSI.This study adhered to the Declaration of Helsinki and was approved by the Medical Ethics Committee of Shenzhen Eye Hospital (No.2021-6-3).Patients were informed of the study methods and purposes.Written informed consent was obtained from each subject.Results:There was no significant difference in BCVA before and after Nd∶YAG laser vitreolysis ( t=-0.478, P=0.635).The floater area before laser treatment was (3.043±1.942)mm 2, which was significantly larger than (1.074±0.735)mm 2 after laser treatment ( t=0.769, P<0.001).The OSI before laser treatment was 1.976±0.975, which was significantly greater than 1.560±0.796 after laser treatment ( t=0.730, P<0.001).The results of linear regression analysis showed that the OSI=1.45+ 0.16× floater area ( F=5.681, P=0.020).No patient had visual acuity loss or intraocular pressure increase and no traumatic cataract or retinal damage occurred. Conclusions:After laser treatment, the floater area decreased, the OSI decreased, and the visual quality of patients improved.The OSI from OQAS Ⅱ and floater area can be used as quantitative evaluation indicators to objectively evaluate the effectiveness of Nd∶YAG laser vitreolysis.

Objective To explore the short-term and long-term efficacy of partial splenic artery embolization(PSE)in the treat-ment of cirrhosis with hypersplenism.Methods A retrospective analysis was conducted on 35 patients with cirrhosis and hyper-splenism who underwent PSE treatment.Data on white blood cell(WBC),red blood cell(RBC),platelet count(PLT),hemoglobin(HGB),total bilirubin(TBiL),albumin(ALB),prothrombin time(PT),and D-dimer were collected at the three time points:before surgery,1 week after surgery,and 1 year after surgery.The changes in these parameters across the three time points were observed and compared.One-way ANOVA was used for repeated measurements,and time pairwise comparisons were made between the three time points.According to the formation of portal thrombosis,patients were divided into thrombus group and no-thrombus group.The D-dimer values were compared before surgery and 1 week after surgery.Results WBC and PLT were significantly higher 1 week and 1 year after surgery than those before surgery,with the most significant increase 1 week after surgery,and there was also statistically sig-nificant difference between 1 week after surgery and 1 year after surgery(P1,P2,P3<0.05).There were no significant differences in RBC and HGB between 1 week after surgery and before surgery(RBC P1=0.835,HGB P1=0.446).However,RBC and HGB 1 year after surgery were significantly higher than those before surgery and 1 week after surgery(RBC P2=0.039,P3=0.015;HGB P2=0.001,P3=0.010).There were significant differences in TBiL,ALB,PT,and D-dimer 1 week after surgery compared with those before surgery(TBiL P1=0.006,ALB P1<0.001,PT P1=0.001,D-dimer P1<0.001),but there was no significant differ-ence between 1 year after surgery and before surgery(all P2>0.05).The D-dimer of the thrombus group was significantly higher than that of the no-thrombus group 1 week after surgery,with a statistical significance(P=0.024),however,there was no signifi-cant difference in D-dimer between the two groups before surgery.Conclusion PSE in the treatment of cirrhosis with hypersplenism shows positive short-term and long-term efficacy for WBC and PLT.The short-term increase of RBC and HGB is not obvious,however the long-term efficacy is significant.In the short-term after surgery,TBiL increase,ALB decrease,PT prolonge,and liver reserve function decrease,but there was no long-term effect.The increase of D-dimer after surgery can easily induce portal thrombosis,and anticoagulation therapy can be given in the short-term after surgery.

Objective:To investigate the comorbidity rate of chronic diseases and prevalence of depressive symptoms among the middle-aged and elderly population,and explore the association between comorbidity with-chronic disease and depressive symptoms in middle-aged and older people.Methods:A cross-sectional study was conducted in Shandong Province.A total of 9 535 middle-aged and older people aged 45 years and over were recrui-ted.General information questionnaire,the chronic disease information questionnaire and Patient Health Question-naire were used for face-to-face interview to screen symptoms and collect information.Univariate analysis and mult-ivariate logistic regression analysis were employed to explore the association between comorbidity with chronic dis-ease and depressive symptoms.Results:The prevalence of depressive symptoms among middle-aged and older peo-ple was 8.7％,while among those with comorbid chronic diseases,the prevalence of depressive symptoms was 29.6％.Respectively,demonstrating an increasing trend with the number of chronic diseases(P＜0.001).Multiva-riate analysis revealed that comorbid chronic disease(OR=1.47,95％CI:1.22-1.78)were risk factors of depres-sive symptoms.Conclusion:Middle-aged and older people with multiple chronic conditions are more likely to be di-agnosed with depressive symptoms,and the detection rate of these symptoms increases with the number of comorbid chronic conditions.Therefore,it is recommended to strengthen mental health interventions for those with multiple chronic conditions.

Background and Aims:Papillary thyroid carcinoma(PTC)is the most common endocrine malignancy in China,with cervical lymph node metastasis being a frequent and critical clinical feature that directly affects patient prognosis and recurrence risk.In recent years,with the rapid increase in the prevalence of overweight and obesity in China,the role of body mass index(BMI)in various tumors has attracted growing attention.This study aimed to investigate the association between overweight and cervical LNM in PTC,analyze sex-specific differences and influencing factors,and provide evidence for precise clinical management.Methods:A retrospective analysis was conducted on the clinicopathologic data of 1 445 patients with classical PTC treated at Xiangya Hospital of Central South University between August 2021 and June 2022.Patients were divided into groups based on the presence or absence of lymph node metastasis.Restricted cubic spline analysis explored the nonlinear relationship between BMI and lymph node metastasis risk.Univariate and multivariate Logistic regression analyses were applied to identify independent risk factors.Furthermore,sex-stratified analysis was performed among overweight patients(BMI≥24 kg/m2)to determine sex-specific risk factors for lymph node metastasis.Results:Among all patients,716(49.6%)had lymph node metastasis.Univariate analysis showed that BMI,sex,age,tumor diameter,multifocality,and extrathyroidal extension were significantly associated with cervical lymph node metastasis in PTC patients(all P<0.05).A nonlinear positive correlation was observed between BMI and lymph node metastasis risk,which was more pronounced in male patients.Additionally,BMI was positively correlated with triglyceride levels and negatively correlated with high-density lipoprotein cholesterol.Sex-stratified analysis revealed that in overweight male patients,younger age(OR=0.954),larger tumor diameter(OR=1.085),and multifocality(OR=2.776)were independent risk factors for LNM;in overweight female patients,younger age(OR=0.943)and larger tumor diameter(OR=1.074)were the main influencing factors.Conclusion:Overweight is closely associated with cervical lymph node metastasis in PTC,and the high-risk factors for LNM differ between male and female overweight patients.Young age,larger tumor size,and multifocality in overweight males,and young age and larger tumors in overweight females indicate a higher risk of metastasis.It is recommended that high-risk populations receive enhanced preoperative evaluation and individualized lymph node dissection strategies to achieve precise treatment and improved risk control.
