AIM: To evaluate the safety and efficacy of low-dose transscleral cyclophotocoagulation(TSCP)in the management of persistent ocular hypertension after an acute attack of angle-closure glaucoma(AACG).METHODS:This retrospective study enrolled patients diagnosed with persistent ocular hypertension after an acute AACG attack at the No.988 Hospital of the Joint Logistics Support Force of the Chinese PLA between September 2023 and September 2024. All patients underwent low-dose TSCP using a semiconductor diode laser. Subsequent cataract surgery combined with goniosynechialysis was performed once intraocular pressure(IOP)was stabilized. Changes in anterior chamber depth(ACD), best-corrected visual acuity(VA), and IOP were compared before and after TSCP, as well as before and after phacoemulsification. Post-TSCP complications were also documented.RESULTS: A total of 21 patients(21 eyes)were enrolled, including 8 males and 13 females, with a mean age of 67.95±7.25 y. Compared with pre-cyclophotocoagulation values, ACD increased significantly at 3 d post-TSCP(1.49±0.18 vs 1.22±0.21 mm; P<0.001). BCVA and IOP decreased significantly at 1 d post-TSCP, pre-phacoemulsification, 1 wk post-phacoemulsification, and 1 mo post-phacoemulsification compared with pre-TSCP IOP(all P<0.01). Regarding postoperative complications, 2 eyes experienced pain on the day of the procedure, 5 eyes developed mild corneal endothelial folds, 2 eyes exhibited moderate anterior chamber inflammatory reaction, and 12 eyes showed shallow ciliary body detachment. No serious complications occurred during the 1-month follow-up period.CONCLUSION:Low-dose TSCP appears to be an effective bridging therapy for patients with persistent ocular hypertension following an AACG attack. It facilitates rapid IOP reduction, alleviates symptoms, and helps preserve visual function with a favorable safety profile, thereby reducing the risks associated with subsequent intraocular surgery.

Objective To elucidate the changes in the gut microbiota and molecular mechanism of huaier in enhancing the efficacy of oxaliplatin (OXA) chemotherapy in gastric cancer (GC). Methods The effects of huaier on the gut microbiota structure and intestinal barrier function in MKN45-bearing mice were analyzed by using 16S rRNA sequencing, RT-qPCR, and IHC. UPLC-MS and network pharmacology, as well as in vivo experimental approaches, were employed to investigate the key bioactive constituents of huaier systematically and elucidate the underlying mechanisms by which huaier exerts therapeutic effects against GC. The expression of the PI3K/AKT/SREBP pathway was detected in cancer cells and tissues via Western blot analysis. The safety profile of huaier combined with OXA was verified through serum biochemistry and HE-stained tissue section analyses. Results Huaier inhibited the PI3K/AKT/SREBP pathway by increasing the abundance of Akkermansia muciniphila, reduced lipid droplet deposition, and ultimately enhanced the sensitivity to OXA in the treatment of GC. Conclusion This study demonstrates the value of huaier in gastric cancer treatment by enhancing chemosensitivity and provides novel insights into its systemic therapeutic effects through molecular mechanisms and gut microbiota modulation.

Objective:To construct an evaluation system for the risk factors of PICC catheter malposition in patients with hematological diseases, providing a reference for the prevention of central venous access malposition in these patients.Methods:From July 2022, a literature review was conducted to retrieve literature published in database and website such as PubMed, Web of Science domestically and internationally related to the risk assessment system of PICC catheter malposition in hematology patients. After full-text screening and extraction, the articles were included in the system′s item pool. Through further discussions among the research group′s experts, in conjunction with evidence-based findings, the system′s consultation items were formulated. Using the Delphi expert consultation method, a standard for PICC catheter malposition risk assessment system applicable to hematology patients was ultimately formulated.Results:In this study, 25 experts were invited for consultation: 24 females and 1 male, with an average age of (48.36 ± 6.82) years. After two rounds of expert consultations and revisions, the risk factors for PICC catheter malposition in hematology patients were identified to include 4 first-level indicators: patient factors, treatment factors, catheter-related factors, and operational factors, along with 11 second-level indicators and 25 third-level indicators. The positive coefficients of the experts in the two rounds of consultations were 84% and 100%, respectively; the Kendall coordination coefficients were 0.22 and 0.55 (both P<0.05); and the expert authority coefficient was 0.93. Conclusions:The risk assessment scale for PICC catheter malposition in patients with hematological diseases has high expert recognition and good consistency, and has clinical practice and guiding value.

[Objective]To evaluate the utility of left atrial(LA)volume and strain measured by 4D auto left atrial quantification(4D auto LAQ)in differentiating pre-capillary from post-capillary pulmonary hypertension(PH),and to compare its discriminative performance with echocardiographic pulmonary to left atrial global strain ratio(ePLAGS).[Methods]A total of ninety-eight subjects with intermediate to high probability of PH were prospectively enrolled.Clinical history and laboratory data were collected.All patients underwent comprehensive transthoracic echocardiography,and LA volume and strain parameters were measured by dedicated commercial software for LA 4D analysis.[Results]Based on pulmonary arterial wedge pressure,patients were divided into pre-capillary PH group[n=39;mean age(53±24)years]and post-capillary PH group[n=59;mean age(57±18)years].Compared to the pre-capillary PH group,the post-capillary PH group showed significantly higher LAVImax,LAVImin and LAVIpreA but markedly lower LASr and LAScd.Multivariate logistic regression identified LAVImax[OR:1.40;95%CI:(1.052,1.872);P=0.021]and LAScd[OR:1.76;95%CI:(1.183,2.489);P=0.004]as independent predictors of post-capillary PH.ROC analysis demonstrated that LAVImax(AUC=0.82,P＜0.001)and LAScd(AUC=0.78,P＜0.001)had strong discriminating power for predicting post-capillary PH group,with optimal cutoff values of 35.69 mL/m2(sensitivity 86%,specificity 74%)and-9%(sensitivity 80%,specificity70%).[Conclusion]LAVImax and LAScd measured with 4D auto LAQ are robust parameters for distinguishing pre-capillary PH from post-capillary PH.

Objective To observe the analgesic and rehabilitation effects of non μ-opioids anesthesia/analgesia(NΜOA)based on quadratus lumborum block(QLB)in emergency cesarean section under general anesthesia.Methods The retrospective study method was adopted,50 pregnant women undergoing hysterectomy under emergency general anesthesia in Langfang People's Hospital from January 2023 to December 2024 were selected as the study objects.The patients were divided into μ-opioids anesthesia/analgesia(ΜOA)group and NΜOA group according to different anesthesia/analgesia methods,25 cases in each group.ΜOA group received ΜOA;NΜOA group received NΜOA+QLB.Incisional pain and uterine contraction pain numerical rating scale(NRS)at out of the post-anesthesia care unit(T1),intravenous injection of oxytocin(T2),press the palace bottom 24 hours(T3),out of bed activity after operation(T4)and first analgesic time of incision pain,first analgesic time of uterine contraction pain,first no vomiting eating time,first exhaust time was observed and recorded.The incidence of vasoactive agents during the anesthetic period,rescue analgesia,rescue antiemetic,constipation,sleep disturbance after operation within 48 hours after operation were also recorded.Results The NRS scores at T1,T2,T3 and T4 in ΜOA group were significantly higher than those in NΜOA group(incisional pain 3.36±1.25 vs.1.12±0.97,3.68±1.18 vs.2.00±0.91,5.76±1.67 vs.4.20±1.00,4.48±1.29 vs.3.32±0.95;uterine contraction pain 3.72±1.49 vs.1.24±1.05,4.64±1.60 vs.3.04±1.27,7.56±1.71 vs.5.16±1.37,3.56±0.22 vs.2.56±0.16,all P<0.05).The first analgesic time of incision pain,first analgesic time of uterine contraction pain in ΜOA group were significantly less than that in NΜOA group(hours:3.06±2.02 vs.17.48±10.93,2.68±2.22 vs.15.80±11.39,both P<0.05),the first no vomiting eating time,first exhaust time in ΜOA group were significantly longer than those in NΜOA group(hours:8.56±0.57 vs.6.32±0.14,15.44±1.42 vs.10.16±1.14,both P<0.05),the incidence of vasoactive agents,rescue analgesia,rescue antiemetic,constipation,sleep disturbance after operation within 48 hours in ΜOA group were significantly higher than those in NΜOA group[64.0%(16/25)vs.32.0%(8/25),48.0%(12/25)vs.20.0%(5/25),44.0%(11/25)vs.16.0%(4/25),64.0%(16/25)vs.36.0%(9/25),60.0%(15/25)vs.32.0%(8/25),all P<0.05].Conclusion NΜOA based on QLB safely and effectively reduced side effects of μ-opioids and enhanced recovery compared to ΜOA on emergency cesarean section patients undergoing general anesthesia.

Objectives:To investigate the predictive value of epicardial fat volume(EFV)and atrioventricular groove fat thickness(AVGT)—morphological biomarkers of epicardial adipose tissue—for major adverse cardiovascular events(MACE)in patients with dilated cardiomyopathy(DCM).Methods:This study enrolled 216 DCM patients.EFV and AVGT were obtained from cardiac magnetic resonance imaging(CMR).Patients were divided into event-free group(n=142)and event group(n=74)based on MACE occurrence during follow-up.Receiver operating characteristic(ROC)curve analysis was used to determine optimal cutoff values.Survival differences were assessed using Kaplan-Meier analysis,Cox proportional hazards regression analysis was used to identify independent risk factors,and restricted cubic spline(RCS)models were used to evaluate dose-response relationships.Results:AVGT and EFV were significantly higher in the event group than in event-free group(both P<0.05).ROC analysis identified optimal MACE-predicting cutoffs as follows:AVGT≥7.74 mm(area under the curve[AUC]=0.57)and EFV≥78.6 ml(AUC=0.62).Kaplan-Meier analysis revealed significantly lower MACE-free survival rates in patients with AVGT≥7.74 mm and EFV≥78.6 ml(both P<0.05).Cox regression analysis confirmed that AVGT(HR=2.18,95%CI:1.34-3.54)and EFV(HR=1.81,95%CI:1.11-2.96)were independent MACE risk factors(both P<0.05)in this patient cohort.RCS models demonstrated the significant linear associations between EFV/AVGT and MACE risk(bothoverall P<0.05).Conclusions:EFV and AVGT,the non-invasive imaging biomarkers quantifying and characterizing fat distribution,are independently correlated with elevated MACE risk in DCM patients.These metrics serve as potential prognostic indicators,enriching risk stratification indicators for early identification of high-risk patients and guiding personalized medication strategies.

Objective:To investigate the application effect of quadratus lumborum block (QLB) combined with less opioid anesthesia analgesia in laparoscopic total hysterectomy (LTH) in elderly patients with uterine prolapse.Methods:A total of 86 elderly patients with uterine prolapse who received LTH in the Langfang People’s Hospital from Jan. 2021 to Oct. 2023 were prospectively selected and divided into group A ( n=42) and group B ( n=44) according to the random number table method. Group A received transversus abdominis block (TAPB) + general anesthesia, and group B received QLB combined with less opioid anesthesia + general anesthesia. The pain duration at different time points after operation [Numeric Rating Scale (NRS) method to evaluate resting incision and visceral pain] was compared between the two groups. The dosage of opioids and the additional analgesia rate were compared between the two groups. The sleep quality of the two groups before and 72 hours after operation was compared, and the adverse reactions of anesthesia were counted. Results:Compared with 6 h after operation, NRS scores of resting incision pain and visceral pain in the two groups decreased gradually at 12, 24 and 48 h after operation, and it was lower in group B than in group A. There were statistically significant differences between groups ( P<0.05) . Dosage of sufentanil and remifentanil in group B was lower than that in group A, and the postoperative additional analgesia rate in group B (9.09%) was lower than that in group A (28.57%) ( P<0.05) . 72 hours after surgery, the sleep efficiency and total sleep time of patients in both groups were lower than those before surgery, and they were higher in group B than in group A; The awakening time and number of awakenings in both groups were higher than those before surgery, while they were lower in group B than in group A ( P<0.05) . The total incidence of adverse reactions in group B was 4.76% (2/44) , lower than 23.81% (10/42) of group A ( P<0.05) . Conclusion:QLB combined with less opioid anesthesia analgesia can effectively reduce the degree of incision and visceral pain after LTH in elderly patients with uterine prolapse, reduce the amount of opioids used during operation and the rate of additional analgesia, and reduce the incidence of adverse reactions of anesthesia.

Objective This study aims to investigate the effects of transcatheter arterial chemoembolization(TACE)using EqualSpheres,CalliSpheres,and Lipiodol loaded with idarubicin on VX2 liver cancer in rabbits.Methods Twelve New Zealand white rabbits were randomly assigned to three groups:EqualSpheres group,CalliSpheres group,and Lipiodol group(n=4 per group).The VX2 liver cancer animal model was successfully established through ultrasound-guided percutaneous puncture.EqualSpheres,CalliSpheres,and Lipiodol were employed as embolization agents loaded with idarubicin for the embolization procedure.Peripheral blood samples were collected at intervals of 5 minutes,0.5,1,4,12 and 24 hours following embolization and were centrifuged to obtain serum.At 24 hours post-TACE treatment,the rabbits in both the experimental and control groups were euthanized,and both liver cancer tissues and normal liver tissues were collected.UPLC-MS/MS was used to measure the drug concentration of idarubicin in peripheral blood and tissue samples,and Graphpad software was used to construct drug concentration-time curves in peripheral blood.The pharmacokinetic curves were constructed to evaluate the dynamic in vivo distribution characteristics.Results The average drug concentration in the EqualSpheres group(920.06 ng/mL)was significantly higher than that in both the CalliSpheres group(79.47 ng/mL)and the Lipiodol group(118.71 ng/mL).However,the average drug concentration in normal liver tissue of all the three groups was lower,and the difference was not statistically significant.The peripheral blood drug concentration of the three groups decreased at 5 minutes post-TACE and increased over the next 24 hours.The average blood concentration curve of EqualSpheres group increased more steadily compared to the CalliSpheres group and the Lipiodol group.The Cmax of the Lipiodol group was reached at 0.5 hours,measuring 11.54 ng/mL.Both the CalliSpheres group and the EqualSpheres group achieved their Cmax at 5 minutes,with values of 7.82 and 8.36 ng/mL,respectively.Conclusion EqualSpheres loaded with idarubicin achieve a high drug concentration at the tumor site while maintaining a low concentration in peripheral blood over 24 hours.This study demonstrates the stable drug release capability of idarubicin-loaded EqualSpheres.
