Objective To explore the related risk factors of osteosarcopenia (OS) in elderly patients with type 2 diabetes mellitus (T2DM) and to evaluate their predictive value. Methods We selected 409 elderly patients with T2DM from our hospital between June 2021 and December 2024 as the study subjects, and divided them into an OS occurrence group and a non-occurrence group based on whether they were diagnosed with OS. Results Among the 409 elderly patients with T2DM included, 93 were diagnosed with OS, yielding a prevalence rate of 22.73%. Spearman correlation analysis revealed a significant association between lumbar spine BMD and T-scores with age, history of previous fractures, fasting plasma glucose (FPG), procollagen type I N-terminal propeptide (PINP), osteocalcin (OC), and 25-hydroxyvitamin D (25(OH)D). Gender (OR=0.193), Body Mass Index (BMI) (OR=0.254), history of previous fractures (OR=8.883), FPG (OR=0.543), Total Cholesterol (TC) (OR=3.684), High-Density Lipoprotein Cholesterol (HDL-C) (OR=86.024), PINP (OR=0.818), and OC (OR=0.526) are identified as influential factors for the occurrence of OS in elderly patients with T2DM. The combined prediction of these variables yields a sensitivity of 96.5%, a specificity of 97.8%, and an area under the curve (AUC) of 0.992 for the occurrence of OS in elderly patients with T2DM, indicating an excellent predictive performance. Conclusion The following factors—gender, BMI, history of previous fractures, FPG, TC, HDL-C, PINP, and OC—are influential in the occurrence of OS among elderly patients with T2DM. Formulating intervention measures based on these influencing factors can provide assistance in preventing and treating the occurrence of OS.

AIM: To compare the changes in corneal epithelial thickness(CET)after small incision lenticule extraction(SMILE)and femtosecond laser-assisted in situ keratomileusis(FS-LASIK).METHODS: A total of 187 patients(187 eyes)who underwent either SMILE or FS-LASIK at Urumqi Aier Eye Hospital between December 2022 and November 2023 were collected. The patients were divided into SMILE group and FS-LASIK group according to surgical methods. The CET of the patients was measured by optical coherence tomography(OCT)system before surgery and at 1 wk, 1, 3, and 6 mo postoperatively.RESULTS: Changes in corneal epithelial thickness(△CET)in the central, paracentral, and mid-peripheral regions were compared at 6 mo postoperatively. The SMILE group was characterized by the most significant thickening in the central area and the least thickening in the mid-peripheral area; while the FS-LASIK group was characterized by the most significant thickening in the paracentral area and the least thickening in the mid-peripheral region. At 1 wk, 1, 3, and 6 mo postoperatively, within the 0-7 mm corneal area, the △CET for both the SMILE and FS-LASIK groups was correlated with the preoperative spherical equivalent.CONCLUSION: Within 6 mo postoperatively, both SMILE and FS-LASIK showed a similar trend in epithelial thickening but with distinct characteristics. The change in corneal epithelial thickness for both procedures was positively correlated with the preoperative diopter.

Ulcerative colitis(UC)is an idiopathic,relapsing,and etiologically complicated chronic inflammatory bowel disease.Despite substantial progress in the management of UC,the outcomes of mucosal barrier repair are unsatisfactory.In this study,phillygenin(PHI)treatment alleviated the symptoms of chronic colitis in mice,including body weight loss,severe disease activity index scores,colon shortening,splenomegaly,oxidative stress,and inflammatory response.In particular,PHI treatment ameliorated the tight junction proteins(TJs)reduction,fibrosis,apoptosis,and intestinal stem cell activity,indicating that PHI exerted beneficial effects on the intestinal mucosal barrier in mice with chronic colitis.In the NCM460 cells damage model,dextran sulfate sodium triggered the sequential induction of TJs reduction,fibrosis,and apoptosis.Takeda G protein-coupled receptor-5(TGR5)dysfunction mediated NCM460 cell injury.Moreover,PHI treatment enhanced TJs and suppressed fibrosis and apoptosis to maintain NCM460 cell function,depending on TGR5 activation.PHI promoted TGR5 activation and elevated intracellular cyclic adenosine monophosphate levels in HEK 293T cells transfected with TGR5 expression plasmids.Cellular thermal shift assay and molecular docking studies confirmed that PHI directly binds to TGR5,indicating that PHI is an agonist of TGR5.The process of PERK-eIF2α pathway-mediated endo-plasmic reticulum Ca2+release was involved in NCM460 cell injury as well,which was associated with TGR5 dysfunction.When NCM460 cells were pretreated with PHI,the PERK-eIF2α pathway and elevated Ca2+levels were blocked.In conclusion,our study demonstrated a novel mechanism that PHI inhibited the PERK-eIF2α-Ca2+pathway through TGR5 activation to against DSS-induced TJs reduction,fibrosis,and apoptosis.

Objective To explore the mechanism of Gandou Fumu Decoction(GDFMD)for improving Wilson's disease(WD)in tx-J mice.Methods With 6 syngeneic wild-type mice as the control group,30 tx-J mice were randomized into WD model group,low-,medium-and high-dose GDFMD treatment groups,and Fer-1 treatment group.Saline(in control and model groups)and GDFMD(3.48,6.96 or 13.92 g/kg)were administered by gavage,and Fer-1 was injected intraperitoneally once daily for 14 days.Oil red and HE staining were used to observe lipid deposition and pathological conditions in the liver tissue;ALT,AST,albumin,AKP levels were determined to assess liver function of the mice.Western blotting and RT-qPCR were used to detect hepatic protein and mRNA expressions of GPX4,ACSL4,ALOX15,FTH1,FLT,TFR1,FAS,SCD1,and ACOX1,and Fe2+,MDA,ROS,SOD,GSH and 4-HNE levels were analyzed to assess oxidative stress.Results The mouse models of WD showed obvious fatty degeneration in the liver tissue significantly increased serum levels of ALT,AST and AKP,decreased albumin level,increased Fe2+,MDA,ROS,4-HNE levels,decreased SOD and GSH levels(P<0.05),lowered protein expressions of ACOX1,GPX4,FTH1,FLT,FAS,and SCD1,and increased protein contents of TFR1,ACSL4 and ALOX15 in the liver.Treatment with GDFMD and Fer-1 improved liver histopathology and liver function of the mouse models,decreased the levels of Fe2+,MDA and ROS,increased SOD and GSH levels,and reversed the changes in hepatic protein expressions.Conclusion GDFMD improves liver steatosis in mouse models of WD possibly by inhibiting hepatocyte ferroptosis through the GPX4/ACSL4/ALOX15 signaling pathway.

Objective To explore the safety and feasibility of posterior quadratus lumborum block(PQLB)in patients undergoing laparoscopic myomectomy.Methods A retrospective analysis was conducted on clinical data of 62 gynecological patients who underwent laparoscopic myomectomy from July 2021 to July 2024.The patients were divided into two groups based on the preoperative blocking method:the PQLB group and the transversus abdominis plane block(TAP)group,with 31 patients in each group.In the PQLB group,bilateral PQLB was performed under ultrasound guidance with 20 ml of 0.35％ropivacaine on each side.In the TAP group,bilateral transversus abdominis plane blocks were performed under ultrasound guidance with 20 ml of 0.4％or 0.5％ropivacaine on each side.The mean arterial pressure and heart rate were recorded before anesthesia(T0),at the time of the block(T1),at skin incision(T2),and during the recovery period(T3).The local anesthetic toxicity,nerve injury,intraoperative opioid consumption,postoperative remedial analgesic usage and dosage,as well as the incidence of nausea and vomiting,were monitored.Results The operations were successfully completed in all the 62 patients.No significant differences were observed between the two groups in mean arterial pressure(F=0.323,P=0.572)and heart rate(F=0.195,P=0.660)at 4 different time points.There were no significant differences in the dosage of anesthetic analgesics during surgery(Z=-0.458,P=0.647)and length of hospital stay(Z=-1.652,P=0.099)between the two groups.The postoperative remedial analgesic usage rate in the PQLB group was significantly lower than that in the TAP group(32.3％vs.74.2％,x2=10.949,P=0.000).Within 48 h after operation,the use of non-steroidal anti-inflammatory drugs(NSAIDs)dosage in the PQLB group was significantly lower than that in the TAP group[0(0,0)mg vs.400(0,1600)mg,Z=-4.849,P=0.000],and no significant difference was observed between the two groups in the use of opioid(tramadol)dosage(Z=-0.045,P=0.964).There was no significant difference in the incidence of postoperative nausea and vomiting(P＞0.05).The scores of numeric rating scale for abdomial wall pain and visceral pain in the PQLB group at 12 and 24 h after surgery did not exceed 3 points.No local anesthetic toxicity or nerve injury was observed.Conclusion PQLB provides effective analgesia for patients undergoing laparoscopic myomectomy,offering better control of visceral pain,helping reduce intraoperative opioid consumption,and lowering the risk of postoperative adverse reactions.

Background and Aims:Abdominal aortic aneurysm(AAA)is a common arterial dilation disease in vascular surgery,with aneurysm rupture being its most serious complication,often leading to fatal hemorrhage and posing a severe threat to patients'lives.Endovascular aneurysm repair(EVAR),due to its minimally invasive nature,safety,and rapid recovery,has become the preferred treatment for AAA.However,endoleak,a complication unique to EVAR,remains a major clinical challenge.Persistent endoleak can lead to sustained high pressure within the aneurysm sac,increasing the risk of continued expansion and rupture.It is one of the main causes of the high reintervention rate following EVAR.In particular,the treatment strategy for type Ⅱ endoleaks remains controversial.This study was conducted to evaluate the clinical value of selective sac embolization via the iliac approach combined with standard EVAR in managing intraoperative immediate endoleaks.Methods:The clinical data of AAA patients with a risk of endoleak who underwent standard EVAR at the First Hospital of China Medical University between March 2023 and September 2024 were retrospectively collected.Patients were divided into an intervention group(n=42)and a non-intervention group(n=32)based on whether selective sac embolization via the iliac approach was performed during operation.General clinical data,preoperative anatomical characteristics of the AAA,surgical details,and postoperative follow-up results were compared between the two groups.Results:There were no statistically significant differences between the two groups in terms of age,sex,anatomical features,rupture rate,or off-label use(all P>0.05).The technical success rate during surgery was 100%in both groups.One patient in the intervention group experienced transient sigmoid colon ischemia after operation,which resolved with conservative treatment.The mean follow-up period was(6.49±4.68)months.The proportions of aneurysm sac shrinkage,stability,and enlargement in the intervention group were 40.5%,57.1%,and 2.4%,respectively,compared to 59.4%,40.6%,and 0.0%in the non-intervention group,with no statistically significant differences(all P>0.05).The incidence of endoleak during follow-up was also comparable between the two groups(P>0.05).Conclusion:For intraoperative endoleaks during standard EVAR,selective sac embolization via the iliac approach is a technically simple and safe method that provides short-term outcomes comparable to those in patients without intraoperative endoleaks.Its long-term efficacy warrants further investigation through extended follow-up.

Objective:To evaluate the effect of robot-assisted laparoscopic technology via abdominal approach for patients with primary retroperitoneal tumors.Methods:A retrospective cohort analysis was conducted for the clinical data of 71 patients who underwent robot-assisted laparoscopic resection of primary retroperitoneal tumor via abdominal approach at the Department of Urology of Sir Run Run Shaw Hospital,Zhejiang University School of Medicine from January 2015 to December 2023. There were 35 male and 36 female patients. The age ( M(IQR)) was 56(21) years (range: 21 to 83 years). The median tumor diameter was 46 (31) mm (range: 15 to 134 mm). Postoperative pathology revealed 58 benign and 13 malignant cases. Patients were divided into non-adherent group ( n=47) and adherent group ( n=24) based on whether the tumor was adhered to major organs or vessels. Perioperative and postoperative situation were compared between the two groups. Data comparisons were conducted using independent samples t-test for normally distributed continuous variables, Mann-Whitney U tests for non-normally distributed data, χ2 test or Fisher′s exact test for categorical variables. Kaplan-Meier survival analysis was employed to estimate 3-year recurrence or metastasis rate and 3-year mortality rate. Results:Operative time was 120(60) minutes (range: 45 to 440 minutes), intraoperative blood loss was 50 (80) ml (range: 10 to 2 000 ml). The median change of intraoperative mean arterial pressure was 40 (19) mmHg(1 mmHg=0.133 kPa)(range: 10 to 112 mmHg). Intraoperative blood transfusion was required in 7 cases, whereas 64 cases did not necessitate transfusion. The change in hemoglobin levels before and after surgery was (17.9±13.6) g/L (range:-16 to 53 g/L), and the median change in serum creatinine levels was 2.0 (14.5) μmol/L (range:-71.0 to 100.4 μmol/L). Postoperative fasting duration was 2.0 (1.5) days (range: 1 to 6 days), and the median hospital stay was 10.0 (7.5) days (range: 4 to 24 days). No perioperative mortality occurred in any of the patients. The non-adherent group had shorter operation time, less estimated blood loss, lower blood transfusion rate, smaller delta value of hemoglobin before and after surgery, larger delta value of creatinine before and after surgery, fewer postoperative complications, shorter postoperative fasting time, and shorter length of hospital stay than the adherent group(all P<0.05), while there was no significant difference in mean arterial pressure fluctuation between the two groups ( P>0.05). Follow-up data were available for 69 patients, with a median follow-up duration of 39 (43) months (range: 4 to 88 months). Among these patients, 40 completed the 3-year follow-up. The 3-year recurrence or metastasis rate was 10.14%, and the 3-year mortality rate was 2.90%. Conclusions:Robot-assisted laparoscopic technology via abdominal approach for resection of primary retroperitoneal tumors is safe and feasible. It can also achieve secure surgical outcome for primary retroperitoneal tumors adherent to surrounding organs or vessels, albeit with increased surgical complexity and slower postoperative recovery compared to non-adherent cases.

Objective To evaluate the efficacy and safety of combining ureteroscopic holmium laser lithotripsy with microchannel percutaneous nephrolithotomy(mPCNL)in the treatment of upper urinary tract calculus.Methods From September 2020 to September 2023,300 patients diagnosed with upper urinary tract calculus were randomly divided into control group 1,control group 2,and the combined group by random number table method,100 patients in each.Control group 1 received treatment via ureteroscopic holmium laser lithotripsy,control group 2 underwent mPCNL,while the combined group was treated with a combination of ureteroscopic holmium laser lithotripsy and mPCNL.The perioperative indicators,serum inflammatory factor levels,pain scores,and incidence of complications were compared among the three groups.Results The stone clearance rate of the combined group was higher than that of control group 1 and control group 2,the surgical time was longer than that of control group 1 and control group 2,and the hospitalization time was shorter than that of control group 1 and control group 2,but the intraoperative bleeding volume of control group 1 was less than that of combined group and control group 2,the differences were statistically significant(P<0.05).Compared with before surgery,the levels of tumor necrosis factor-α(TNF-α)in three groups was increased 1 h after surgery;Compared with 1 h after surgery,the levels of TNF-α in three groups were decreased at 12 and 24 h after surgery,the differences were statistically significant(P<0.05).The procalcitonin(PCT)levels of the three groups at 1 and 12 h after the operation were significantly higher than those before the operation.The PCT level at 24 h after the operation was significantly lower than that at 12 h after the operation,but significantly higher than that before the operation and 1 h after the operation in three groups,the differences were statistically significant(P<0.05).At 1,12,and 24 h after surgery,the visual analogue scale(VAS)scores of the three groups decreased sequentially,and the control group 1 was lower than that of combined group and control group 1,the difference was statistically significant(P<0.05).The total incidence of complications was no statistically obviously different among the three groups(P>0.05).Conclusion The ureteroscopic holmium laser lithotripsy combined with mPCNL for upper urinary tract calculus has a high stone clearance rate,fast postoperative recovery,and does not increase the incidence of complications.

Objective To investigate the effects of Gandou Fumu Decoction on liver fibrosis,iron metabolism,and ferroptosis in patients with hepatolenticular degeneration(Wilson disease,WD).Methods Seventy-eight hospitalized patients with WD characterized by kidney and liver deficiency,with phlegm and blood stasis,from the Department of Neurology,the First Affiliated Hospital of Anhui University of Chinese Medicine,were randomly assigned to two groups using a random number table method.The control group(n=39)received sodium dimercaptosulfonate in combination with a low-copper and high-protein diet.The observation group(n=39)received the same treatment as the control group,with the addition of Gandou Fumu Decoction(one dose per day,taken twice daily,in the morning and evening).Both groups underwent six treatment cycles,each lasting eight days.Ultrasonographic parameters,including portal vein main trunk diameter(PVMD),portal vein velocity(PVV),shear wave velocity(SWV),liver stiffness measurement(LSM),serum liver fibrosis markers(hyaluronic acid[HA],laminin[LN],procollagen typeⅢN-terminal peptide[PⅢNP],collagen type Ⅳ[CⅣ],aspartate aminotransferase to platelet ratio index[APRI],fibrosis-4 index[FIB-4]),and iron metabolism indicators(serum iron[SI],ferritin[FT])were compared before and after treatment.The relationship between baseline iron metabolism markers and ultrasonographic parameters,as well as serum liver fibrosis markers,was analyzed.Clinical efficacy,traditional Chinese medicine(TCM)syndrome scores,and adverse reactions were also compared between the groups.Additionally,bioinformatics analysis was performed to identify potential targets of Gandou Fumu Decoction for WD treatment.Peripheral blood mononuclear cells were collected from a normal group of 20 healthy individuals,as well as from both the control and observation groups before and after treatment.Real time fluorogenic quantitative PCR was performed to validate the expression changes of these targets across the groups.Results Compared with pre-treatment values,no significant changes were observed in PVMD levels in either group after treatment.No significant change in PVV was observed in the control group,whereas a significant decrease was noted in the observation group(P＜0.01).SWV,LSM,HA,LN,PⅢNP,CⅣ,APRI,FIB-4,and FT levels were significantly reduced compared to pre-treatment levels(P＜0.05,P＜0.01),whereas SI remained unchanged.Compared with the control group,the observation group had no significant difference in PVMD but had significantly lower PVV,SWV,LSM,HA,LN,PⅢNP,CⅣ,APRI,FIB-4,and FT levels(P＜0.05,P＜0.01),whereas SI remained unchanged.The total effective rate of treatment in the observation group was significantly higher than that in the control group(P＜0.05).Both groups showed a significant reduction in TCM syndrome scores after treatment(P＜0.01),with a significantly greater reduction observed in the observation group(P＜0.01).No significant adverse reactions were reported during treatment.Before treatment,there was no significant correlation between the SI of both groups and PVMD,PVV,SWV,LSM,HA,LN,PⅢNP,CⅣ,APRI,and FIB-4.In the observation group,FT showed a positive correlation with SWV,LSM,LN,PⅢNP,CⅣ,APRI,and FIB-4(P＜0.05,P＜0.01),while in the control group,FT showed a positive correlation with HA,LN,PⅢNP,CⅣ,APRI,and FIB-4(P＜0.01).After treatment,in the control group,SI showed a positive correlation with APRI and FIB-4(P＜0.05,P＜0.01),but there was no significant correlation between SI in the observation group and FT in both groups with the above-mentioned indicators.Bioinformatics analysis identified four potential targets of Gandou Fumu Decoction for treating WD,namely heme oxygenase 1(HMOX1),peroxisome proliferator-activated receptor alpha(PPARα),small heat shock protein B1(HSPB1),and mitogen-activated protein kinase 3(MAPK3).Compared to the normal group,both the control and observation groups had significantly lower PPARαand HSPB1 expression and significantly higher HMOX1 and MAPK3 expression before treatment(P＜0.01).Compared to before treatment within the same group,both groups showed significantly increased PPARα and HSPB1 expression and significantly decreased HMOX1 and MAPK3 expression after treatment(P＜0.05,P＜0.01).After treatment,the observation group had significantly higher PPARα and HSPB1 expression and lower HMOX1 and MAPK3 expression than the control group(P＜0.05,P＜0.01).Conclusion Gandou Fumu Decoction demonstrates remarkable advantages in improving clinical efficacy,Chinese medicine syndrome scores,iron metabolism,liver fibrosis progression,ultrasound imaging parameters,and ferroptosis-related biomarkers expression in patients with WD,with a favorable safety profile.

Objective To analyze the predictive value of serum Ficolin-3 combined with National Early Warning Score(NEWS)score in the prognosis of sepsis patients.Methods A total of 120 sepsis patients ad-mitted in the hospital from February 2021 to February 2024 were selected.Serum Ficolin-3 level was detected with samples collected at the time of admission and NEWS score was counted.According to the short-term prognosis,the patients were included in the survival group(n=82)and the death group(n=38).Serum Fico-lin-3 level and NEWS score of all patients were compared.The factors affecting the prognosis of sepsis pa-tients were explored by Multivariate Logistic regression.Results The serum Ficolin-3 and NEWS score in death group were higher than those in survival group(P<0.05).The area under the curve of serum Ficolin-3,NEWS score,and their combined evaluation for predicting the prognosis of sepsis patients were 0.819(95%CI:0.774-0.864),0.764(95%CI:0.714-0.814)and 0.921(95%CI:0.876-0.971),respectively.Arterial oxygen partial pressure(PO2)in the death group was lower than that in the survival group(P<0.05),se-quential organ failure assessment(SOFA)score at admission,acute physiology and chronic health evaluation(APACHEⅡ)score at admission,the proportion of acute kidney injury after admission and diabetes were higher than those in the survival group(P<0.05).Multivariate Logistic regression analysis showed that PO2<70.30 mmHg(OR=2.399,95%CI:1.182-4.867),SOFA score≥7 points at admission(OR=2.479,95%CI:1.306-4.706),APACHEⅡ score≥24 points(OR=2.557,95%CI:1.355-4.826),serum Ficolin-3≥4.16 mg/L(OR=3.421,95%CI:1.750-6.688),NEWS score≥7.15 points(OR=2.921,95%CI:1.661-5.137)were factors affecting the prognosis of sepsis patients(P<0.05).Conclusion High level of serum Ficolin-3 and high NEWS score are closely related to poor short-term prognosis of sepsis patients,and the combination of Ficolin-3 level and NEWS score could effectively improve the predictive value of short-term prognosis of sepsis patients.
