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.

To investigate the pharmacological activities and potential mechanisms of action of the active components in Artemisia argyi with artificial intelligence technology, a search was conducted in the HIT, TCMSP, and TCMIO databases, obtaining 199 active components of A. argyi. A comprehensive set of algorithms, including KNN, MLP, RF, SVM, and models based on Lipinski’s and Veber’s rules, was employed to predict the toxicity and oral bioavailability of A. argyi compounds, identifying 14 components that are non-toxic and have good oral bioavailability. The synthetic accessibility score (SAscore) model was used to analyze the synthetic accessibility of the 14 components mentioned above, and molecular segments were fragmented using BRICS and RECAP algorithms. Mining of the STP and PM databases yielded 406 target proteins for the core components of A. argyi, and Cytoscape was used to screen out 5 core targets: SRC, EGFR, PTPN11, HRAS, and PDGFRB. GO and KEGG enrichment analyses indicated that the core targets were involved in 808 GO enrichment analysis entries and 71 signaling pathways, including EGFR tyrosine kinase inhibitor resistance, gap junction, phospholipase D, and JAK/STAT. Molecular docking results showed that active compounds of A. argyi have a good binding affinity with proteins SRC, EGFR, PTPN11, and HRAS. Cellular experiments have confirmed that ledol, an active component of A. argyi, can promote the proliferation of HUVEC cells within a certain concentration range and can increase the expression of EGFR protein. This study reveals the pharmacological characteristics and potential molecular mechanisms of the active components of A. argyi and lays a solid scientific foundation for its medicinal development.

ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.

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.

Objective:To explore the role of metagenomic next-generation sequencing (mNGS) in the diagnosis of pathogens in primary infectious diseases of the spine (IDS) and to reveal its pathogen spectrum.Methods:This is a retrospective multi-center case series study. Clinical data of 380 patients with primary IDS who were treated at four medical centers in China from December 2019 to April 2024 were retrospectively analyzed. Among them, 82 cases were from the Department of Spine Surgery at the Affiliated Hospital of Qingdao University, 129 cases were from the Orthopedics Section Ⅱ (Bone Infection), Public Health Clinical Center Affiliated to Shandong University, 112 cases were from the Department of Spine Surgery, Fuzhou Second General Hospital, and 57 cases were from the Department of Orthopedic Surgery, Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. There were 238 males and 242 females, with an age of (61.4±13.1) years (range: 10 to 91 years). Specimens from the site of spinal infection were obtained for pathogen culture, pathological examination, and mNGS detection preoperatively or intraoperatively in all patients. The number, types, and positive rates of pathogens detected by the two methods were analyzed and compared using the Chi-square test.Results:Among the 380 patients, 320 had confirmed pathogenic bacteria, with the highest proportion being pyogenic bacterial infections, accounting for 76.9% (246/320). The most common pathogen was Staphylococcus aureus, accounting for 22.8% (73/320). Brucella accounted for 13.8% (44/320); Mycobacterium tuberculosis accounted for 6.3% (20/320). Fungal infections accounted for 3.4% (11/320), mainly Aspergillus and Candida. In addition, Mycoplasma was detected in 3 cases (0.9%) and Benacox body in 4 cases (1.2%). The pathogen spectrum constructed by mNGS covered 46 types of pathogens, higher than the 22 types detected by traditional methods. The positive rate of mNGS was 80.8% (308/381), significantly higher than the 27.9% (106/381) of traditional methods ( χ2=182.53, P<0.01). Conclusions:mNGS improves the positive rate of pathogen diagnosis in IDS, detecting a broader spectrum of pathogens, and serves as a valuable complement to traditional diagnostic methods. Combining both methods in the diagnosis of IDS can maximize detection rates, providing robust evidence for precise anti-infective treatment.

Objective: To investigate the differences in enolase and laminin levels in vaginal epithelial tissues between mice successfully infected withGardnerellaand mice not infected with Gardnerella, providing information for further exploration of the correlation between enolase and laminin levels and the incidence of bacterial vaginosis. Methods: Gardnerella strains isolated, purified, and identified from vaginal secretions of patients with bacterial vaginosis were used to infect the vagina of mice and establish a mouse model of bacterial vaginosis. Successful and failed mice was defined as successful and failed groups, respectively. Differential expression of enolase and laminin in the vaginal epithelial tissue of two groups of mice was detected by Western blot. Modeling success rate was statistically analyzed, and the expression differences of enolase and laminin was compared between two groups. Results: One strain of Gardnerella vaginalis infected 10 SPF grade KM mice, 7 mice met the diagnostic criteria for bacterial vaginosis, and 3 mice failed to model, with a success rate of 70%. Western blot was used to detect protein expression levels, and the levels of laminin and enolase in the successfully modeled mouse vaginal epithelial tissue were significantly higher than those in the failed modeling group, with statistical differences between the two groups(P<0.05). Conclusion Enolase and laminin may be involved in the occurrence of bacterial vaginosis, however, further research is needed to determine the mechanisms through which they trigger the occurrence and development of the disease.

Objective:To observe the proteomic changes in vitreous fluid samples from patients with rhegmatogenous retinal detachment combined with choroidal detachment (RRDCD).Methods:A prospective cross-sectional clinical study. Vitreous fluid samples were collected from 35 patients with RRDCD (RRDCD group) and 40 patients with rhegmatogenous retinal detachment (RRD group) who were diagnosed at Wuhan Aier Eye Hospital between November 2021 and December 2023. Prior to vitrectomy, 0.3-0.5 ml of vitreous fluid was collected from the affected eyes. Differentially expressed proteins were analyzed using Data-Independent Acquisition (DIA). Three of these proteins were randomly selected for validation using enzyme-linked immunosorbent assay (ELISA). Bioinformatics analyses, including gene ontology functional enrichment and kyoto encyclopedia of genes and genomes pathway enrichment, were performed to explore the functions of the differentially expressed proteins.Results:Significant differences were observed between the RRDCD and RRD groups in intraocular pressure ( t=-12.795), the number of retinal tears ( t=4.601), the extent of retinal detachment ( χ2=39.642), axial length ( t=0.840), postoperative proliferative vitreoretinopathy incidence ( χ2=4.730), single-surgery reattachment rate ( χ2=7.717), and best-corrected visual acuity ( t=7.033) at 6 months postoperatively ( P<0.05). A total of 237 differentially expressed proteins were identified between the RRDCD and RRD groups, with 63 upregulated and 174 downregulated. These proteins were involved in pathways such as extracellular matrix-receptor interaction, complement activation, coagulation, and lysosomal pathways. ELISA validation results showed that the expression trends of the three selected proteins in the RRDCD and RRD groups were consistent with the DIA proteomic analysis. Compared to the RRD group, proteins such as fibrin, coagulation factors, cathepsins, and trypsin inhibitors were significantly upregulated in the RRDCD group. Conclusions:The protein expression profile in vitreous fluid samples from RRDCD patients show significant alterations compared to the RRD group. These differential changes suggest that RRDCD is closely associated with complement and coagulation cascade activation, lysosomal pathways, and extracellular matrix remodeling.

Objective:To investigate the incidence and mortality of breast cancer in tumor registration areas of Shanxi Province in 2019.Methods:A cross-sectional study was conducted. The tumor registration data reported by 13 tumor registration areas in Shanxi Province in 2019 were collected, and the overall incidence and mortality of breast cancer were analyzed. The stratified analysis was conducted by gender and region, and the incidence, mortality, accumulation rate (0-74 years old), age-specific incidence rate, age-specific mortality rate, Chinese population standardized rate and world population standardized rate were calculated. The standard population was based on the 2000 China population census standard population composition and Segi world standard population composition.Results:In 2019, there were 871 new cases of breast cancer in the tumor registration areas of Shanxi Province, with an incidence rate of 17.83/100 000, and 202 deaths, with a mortality rate of 4.13/100 000. The age-specific incidence of breast cancer was at a low level in 0-25 years old, it increased rapidly after 30 years old, and reached a peak in people aged 60 years old. The age-specific mortality showed a slow rising trend with the increase of age, and increased rapidly in people over 75 years old. The age-specific incidence and mortality of breast cancer in female were higher than those in male. Although the general trend of change concerning urban and rural age-specific incidence was similar, the trend of change concerning urban and rural age-specific mortality had their own characteristics. In 4 urban tumor registration areas, the highest male and female Chinese population standardized incidence rates were found in Yuci District of Jinzhong City (0.62/100 000) and Yangquan City (41.86/100 000). Male Chinese population standardized mortality rate was 0/100 000, and the highest female Chinese population standardized mortality rate was found in Yangquan City (12.62/100 000). In 9 rural tumor registration areas, the highest male and female Chinese population standardized incidence rates were found in Jishan County (2.59/100 000) and Pingding County (36.42/100 000). The highest Chinese population standardized mortality rates were found in Yuanqu County (0.89/100 000) and Jishan County (4.82/100 000).Conclusions:Women, urban area people and middle-aged and elderly people are the foci of breast cancer prevention and control in Shanxi Province.

Objective:To explore the influencing factors for suffering from malignant tumors in people aged ≥45 years in China.Methods:A cross-sectional study was conducted. Based on data of China Health and Retirement Follow-up Survey (CHARLS) in 2020, univarite analysis of the influencing factors for suffering from malignant tumors in people aged ≥45 years was performed. Logistic regression model under complex sampling was used to perform multivariate analysis.Results:In 2020 CHARLS data, there were 15 923 middle-aged and elderly people aged ≥45 years, and the age of them was (64±10) years old, ranging from 45.0 to 120.5 years old, including 7 473 males (46.93%) and 8 450 females (53.07%), of which 451 (2.83%) people had malignant tumors. The differences in age, gender, urban and rural distribution, noon sleep time, physical activity score, low-intensity physical activity, cancer comorbidity, non-tumor chronic diseases, self-rated health status, social interaction and alcohol consumption between middle-aged and elderly people aged ≥45 years with and without malignant tumors were statistically significant (all P < 0.05). However, the differences in night sleep time, whole day sleep time, moderate-to-vigorous physical activity, social activity, marital status, education level, household registration, pension and medical insurance, and smoking status were not statistically significant (all P > 0.05). Multivariate logistic regression analysis of complex sampling showed that old age ( OR = 1.033, 95% CI: 1.001-1.067, P = 0.042) and bed self-rated health status (very bad vs. not good vs. average vs. good vs. very good: OR = 1.710, 95% CI: 1.183-2.471, P = 0.004) were the independent risk factors for suffering from malignant tumors in Chinese people aged ≥45 years. Conclusions:Based on the 2020 CHARLS data, much attention should be paid to aging and own feelings of middle-aged and elderly people, which may reduce the risk of suffering from malignant tumors among middle-aged and elderly people aged ≥45 years in China.
