BACKGROUND:The stemness index may be associated with the prognosis and immune infiltration of sarcoma,but the specific regulatory mechanism and characteristic genes have yet to be fully elucidated. OBJECTIVE:To investigate the correlation between stem cells and prognosis as well as immune infiltration in sarcoma employing the gene stemness index model and to identify the ferroptosis signature genes associated with sarcoma stem cells. METHODS:The sarcoma RNA sequencing data and related clinical information were obtained from the Cancer Genome Atlas(TCGA).The sarcoma RNA sequencing data were grouped using the sarcoma stemness index.Survival data were used to analyze prognosis between groups.Differentially expressed genes were obtained for pathway enrichment and immune infiltration analysis.Ferroptosis-related differential genes were used to construct a protein interaction network and analyze prognostic correlation.Rhabdomyosarcoma cell lines were cultured and divided into adherent cell group and stem cell group.The adherent cell group received no intervention,while the stem cell group was treated with serum-free culture to enrich stem cells in rhabdomyosarcoma cells.qRT-PCR was used to evaluate stemness markers,ferroptosis-related genes,and mRNA expression of ferroptosis-related markers in the cells. RESULTS AND CONCLUSION:(1)Patients were divided into high and low stemness index groups based on the median stemness index.The progression-free survival of patients in the high stemness index group was lower than that in the low stemness index group by disease risk prediction,suggesting poor prognosis.(2)According to GO and KEGG analysis,the groups with high and low stemness indices differed from one another.There were differences in immune infiltration between the high and low stemness index groups.Nine of the 23 ferroptosis-related genes in the differential genes have the potential to establish a highly correlated network of protein interactions.Patients with high expression of IDO1,IFNG,and AQP5 have a better prognosis,while those with high expression of CA9 have a poor prognosis.(3)The qRT-PCR results demonstrated a significant upregulation of stem cell-related markers NANOG,SOX2,and OCT4 mRNA expressions in the stem cell group compared to the adherent cell group(P<0.05).Compared to the adherent cell group,the stem cell group exhibited decreased mRNA expression level of ferroptosis-related marker SLC7A11(P<0.05)while showing increased levels of ACSL4,GPX4,FTH1,and COX2(P<0.05).Compared to the adherent cell group,the stem cell group displayed decreased mRNA expression level of differentially expressed gene CA9 alongside elevated levels of IDO1,IFNG,and AQP5(P<0.05).Stem cells were strongly associated with sarcoma survival and ferroptosis by bioinformatics analysis and experimental verification.Sarcoma stem cells have aberrant expression of CA9,IDO1,IFNG,and AQP5,which may serve as new targets for sarcoma therapy as well as diagnostic indicators.

Although small in size, the eyeballs are extremely important in function, and are delicate and complex in structure. With the wide application of acupuncture for eye diseases and the high frequency of use of intra-orbital points, the incidence of acupuncture accidents increases accordingly in treatment. We reported two recent accident cases, retinal tear and ciliochoroidal detachment that occurred during the regular operation of acupuncture and acupoint injection at intra-orbital points, in order to strengthen people's awareness of acupuncture accidents caused by acupuncture at the points in the orbital region, and enhance the sound development and comprehensive promotion of acupuncture in treatment of eye diseases.

Objective To explore the correlation of MET status in patients with advanced prostatic acinar adenocarcinoma with the clinical pathological parameters and prognosis. Methods The specimen from 135 patients with advanced prostatic acinar adenocarcinoma was included. The expression of c-MET protein was detected via immunohistochemistry, and MET gene amplification was assessed by fluorescence in situ hybridization. The relationships of c-MET expression and gene amplification with clinicopathological features and prognosis were analyzed. Results The positive expression rate of c-MET was 52.60% (71/135). Compared with the c-MET expression in adjacent tissues, that in tumor tissues showed lower heterogeneous expression. Among the cases, 1.71% (2/117) exhibited MET gene polyploidy, but no gene amplification was detected. Positive c-MET expression was significantly correlated with high Gleason scores and grade groups (P=0.0073). However, no significant relationship was found between c-MET expression and progression-free survival or post-treatment t-PSA levels. Conclusion c-MET protein is expressed at a relatively low level in advanced prostatic acinar adenocarcinoma, suggesting that c-MET may not be a viable target for ADC drug development in prostatic acinar adenocarcinoma.

Objective: To understand the indoor light at night (LAN) exposure intensity during sleep among children and adolescents in Shanghai, so as to provide a basis for exploring potential health risks and formulating effective interventions. Methods: From April to December in 2024, a total of 628 students in grades 4-7 were recruited from three schools in Shanghai. A portable illuminance meter was used to measure LAN for one week, and participants recorded their sleep time. The Kruskal-Wallis H- test was used for comparison between groups, and the error bar chart was used to show the trend and variation range of average LAN exposure intensity in different sleep periods. Results: The indoor LAN exposure intensity of children and adolescents in Shanghai was [2.4(0.8, 5.9)lx] during sleep, and 28.8% of children and adolescents were exposed to indoor LAN≥5 lx. There was no significant differences in indoor LAN exposure intensity between boys [2.4(1.0, 5.9)lx] and girls [2.3(0.7, 5.9)lx] ( Z=-0.86, P > 0.05 ). The indoor LAN exposure intensity of primary school students [2.9(1.1, 6.6)lx] was higher than that of junior high school students [1.0(0.3, 3.1)lx] ( Z =-5.87), and indoor LAN exposure intensity of students in the main urban area [3.2(1.1, 7.8)lx] was higher than that of rural students [1.6(0.5, 4.3)lx] ( Z =-5.23)(both P <0.05). The indoor LAN exposure intensity showed an overall decreasing trend during sleep of children and adolescents ( tau=-0.81, P =0.02), with a slight increase before waking up. Conclusions Indoor LAN exposure intensity among children and adolescents in Shanghai is generally high, especially among primary school students and students living in the main urban area. Health policy and education should be strengthened to reduce the impact of LAN on children and adolescent health.

Objective: To evaluate the effects of a multidisciplinary weight management intervention, so as to provide a reference for the formulation of overweight and obesity intervention measures. Methods: From April to September 2025, overweight and obese residents aged 18-60 years who participated in a weight loss competition at the Health Management Center of Beilun People's Hospital in Ningbo City were selected as study subjects. They were divided into a control group and an intervention group. The control group received conventional weight management, while the intervention group received the multidisciplinary integrated weight management in addition to the conventional weight management, for a total intervention period of 8 weeks. Weight, body mass index (BMI), waist circumference, hip circumference, waist-to-hip ratio, fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and blood pressure were collected before and after the intervention through physical examinations and laboratory tests. The generalized estimating equations (GEE) method was employed to analyze the differences in indicators between the two groups before and after the intervention. Results: The control group comprised 241 participants, including 161 females (66.80%), with a mean age of (35.66±7.80) years. The intervention group consisted of 127 participants, including 86 females (67.72%), with a mean age of (36.80±7.05) years. No statistically significant differences were observed between the two groups at baseline in terms of age, gender, weight, BMI, or waist-to-hip ratio (all P>0.05). Results from the GEE analysis indicated significant interactions between group and time for weight, BMI, waist circumference, and hip circumference (all P<0.05) with greater reductions in these parameters observed in the intervention group compared to the control group before and after the intervention. Similarly, significant interactions between group and time were observed for FBG, TG, TC, and LDL-C (all P<0.05), with the intervention group demonstrating larger decreases in these markers compared to the control group. However, no statistically significant interactions between group and time were observed for waist-to-hip ratio, HDL-C, systolic blood pressure, and diastolic blood pressure (all P>0.05). Following the intervention, a weight loss exceeding 10% was achieved by 13 participants (5.39%) in the control group and 62 participants (48.82%) in the intervention group. The proportion of individuals with a weight loss exceeding 10% was significantly higher in the intervention group compared to the control group (P<0.05). Conclusion Compared to conventional weight management, multidisciplinary integrated weight management demonstrated greater efficacy in improving weight-related indicators and blood glucose, blood lipids, and enhancing weight loss outcomes among overweight and obese residents.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective To investigate the mechanism and clinical significance of miR-18a-5p and retinoid acid receptor-related orphan receptor-α(RORA)in the proliferation and progression of colorectal cancer(CRC)cells.Methods The expressions of miR-18a-5p and RORA in CRC cells and tissues were detected via qRT-PCR,FISH,and IHC.Cell proliferation capability was detected through EdU and CFSE assay,cell apoptosis by flow cytometry assay,and cell migration and invasion abilities by cell scratch and Transwell invasion assays,respectively.The targeted regulation of miR-18a-5p on RORA was further verified via dual-luciferase reporter assay,cell function rescue test,RT-PCR,and Western blot assay.Finally,bioinformatics was used to explore the molecular mechanism of miR-18a-5p promoting malignant proliferation,invasion,and progression of CRC via regulating RORA.Results miR-18a-5p exhibited a high expression in CRC tissues and cells(P<0.05)and promoted the proliferation,migration,and invasion of CRC cells(P<0.05).In addition,RORA served as the target gene of miR-18a-5p,and its overexpression effectively reduced the promoting function of miR-18a-5p in the malignant biological phenotype of CRC cells(P<0.05).The expression of RORA in CRC tissues showed a significantly positively correlation with the infiltration of CD8+T cells and the expression of its surface marker protein CD8A.Conclusion The targeted regulation of RORA by miR-18a-5p promotes the proliferation and progression of CRC.The miR-18a-5p/RORA regulatory pathway possibly contributes to the immune microenvironment of CRC,which can be a potential therapeutic target for CRC.

Recent studies found that the intestinal flora is involved in the occurrence and development of CRC.In particular,Ruminococcus shows a decreased abundance in patients with CRC and can affect gastrointestinal health through cross-feeding and promoting butyrate production.Although the research on Ruminococcus is gradually increasing,no unified understanding of its influence on the occurrence and development of CRC has been established.This work summarizes the relationship of Ruminococcus with CRC and its possible anticancer mechanism to provide a theoretical basis for the further exploration of biological prevention and treatment of CRC in the future.

OBJECTIVE To evaluate the effectiveness and safety of sequential therapy with parathyroid hormone analogues and bisphosphonates for osteoporosis. METHODS PubMed， Embase， the Cochrane Library， Web of Science， China National Knowledge Infrastructure， VIP， Wanfang data， and SinoMed were searched in both English and Chinese databases from their inception to March 25， 2024. Two researchers independently conducted literature searches， screening， and data extraction. Review Manager 5.4 software was used for the meta-analysis. Subgroup analyses and sensitivity analyses were performed based on different medication sequences in the treatment group to account for potential sources of heterogeneity. RESULTS A total of 7 randomized controlled trials involving 2 461 participants were included， with 1 215 in the treatment group and 1 246 in the control group. The meta-analysis results showed that the treatment group using sequential therapy with parathyroid hormone analogues and bisphosphonates had superior effects on improving bone mineral density at the lumbar spine [SMD＝0.90， 95%CI （0.44， 1.35）， P＜0.001]， total hip [SMD=0.68， 95%CI （0.14， 1.21）， P＝0.01]， and femoral neck [SMD＝0.45， 95%CI （0.04， 0.86）， P＝0.03] compared to the control group. It also significantly outperformed the control group in reducing the incidence of fractures post- treatment [OR＝0.72， 95%CI （0.54， 0.97）， P＝0.03].significant difference was noted in the incidence of adverse reactions between the two groups [OR＝1.21， 95%CI （0.99， 1.46）， P＝0.06]. Subgroup analysis based on intervention measures in the treatment group showed that switching from bisphosphonates to parathyroid hormone analogues [SMD＝0.56， 95%CI （0.09， 1.03）， P＝0.02] or switching from parathyroid hormone analogues to bisphosphonates [SMD＝0.97， 95%CI （0.49， 1.46）， P＜0.001] both significantly potentiated lumbar spine bone mineral density compared to the control group. Switching from bisphosphonates to parathyroid hormone analogues also significantly promoted total hip bone mineral density compared to the control group [SMD＝0.66， 95%CI （0.18， 1.13）， P＝0.007]. Sensitivity analysis indicated that the results of this study were robust. CONCLUSIONS Sequential therapy with parathyroid hormone analogues and bisphosphonates can be recommended as an effective treatment for patients with osteoporosis， with good safety profiles. The medication sequences should be individually adjusted based on the patient’s particular situation and the different responses of various skeletal sites.

ObjectiveTo investigate the risk factors for liver cancer in patients with chronic hepatitis B （CHB） in the Qidong Chronic Hepatitis B cohort， and to construct a nomogram model for predicting the risk of liver cancer in CHB patients. MethodsA structured questionnaire survey was conducted among the CHB patients， aged ≥18 years， who attended the outpatient service of Qidong Third People’s Hospital from January 1 to December 31， 2016. The onset of liver cancer was defined as the primary outcome， and the outcomes of the cohort were obtained from Qidong Cancer Registry. Baseline clinical features were compared ；between the liver cancer group and the non-liver cancer group. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The Cox regression model was used to analyze the risk factors for liver cancer in CHB patients and calculate their hazard ratio （HR） and 95% confidence interval （CI）； the variables with statistical significance in the univariate Cox regression analysis were included in the LASSO regression analysis， and then the variables obtained were included in the multivariate Cox regression analysis to establish a predictive model. The nomogram was used to visualize the complex model. The receiver operating characteristic （ROC） curve， index of concordance （C-index）， and the calibration curve were used to assess the predictive efficacy of the model， and the decision curve was used to evaluate the clinical practicability of the nomogram. ResultsA total of 1 479 CHB patients were selected， among whom 58 patients with a confirmed diagnosis of liver cancer， 15 with missing data on testing indicators， and 164 with missing data on important information in the questionnaire were excluded， and finally 1 242 subjects were included in the study. Up to December 31， 2023， there were 67 new cases of liver cancer after a median follow-up time of 7.71 years， and the incidence density of liver cancer was 729.78/100，000 person-years. There were significant differences between the liver cancer group and the non-liver cancer group in age， sex， educational level， liver cirrhosis， duration of liver cirrhosis， history of diabetes mellitus， albumin， total bilirubin （TBil）， direct bilirubin， aspartate aminotransferase， aspartate aminotransferase， gamma-glutamyl transpeptidase （GGT）， and alkaline phosphatase （all P<0.05）. The multivariate Cox regression analysis showed that the increase in age （HR=1.07， 95%CI： 1.05‍ ‍—‍ ‍1.10， P<0.001）， a relatively high level of TBil （HR=1.98， 95%CI： 1.15‍ ‍—‍ ‍3.42， P=0.014）， a relatively high level of GGT （HR=2.41， 95%CI： 1.43‍ ‍—‍ ‍4.08， P=0.001）， and a long duration of liver cirrhosis （HR=1.09， 95%CI： 1.02‍ ‍—‍ ‍1.15， P=0.009） were independent risk factors for liver cancer in CHB patients. A nomogram prediction model was constructed based on the above four indicators， with an area under the ROC curve of 0.790， 0.845， and 0.829， respectively， in predicting the risk of liver cancer in CHB patients at 1， 3， and 5 years， and the bootstrap resampling method was used for internal validation and showed a C-index of 0. 778. The calibration curve showed that the prediction model had good stability， and the decision curve showed that it had certain clinical practicability. ConclusionThe increase in age， relatively high levels of TBil and GGT， and a long duration of liver cirrhosis are independent risk factors for liver cancer in CHB patients， and the nomogram model constructed based on these factors has a good predictive value and can be used in clinical practice to help develop strategies for the long-term monitoring of liver cancer.
