Background/Aims: Endoscopic radiofrequency ablation (ERFA) is a treatment option for superficial esophageal squamous cell neoplasia (ESCN), with a relatively low risk of stenosis; however, the long-term outcomes remain unclear. We aimed to compare the long-term outcomes of patients with widespread superficial ESCN who underwent endoscopic submucosal dissection (ESD) or ERFA. Methods: We retrospectively analyzed the clinical data of patients with superficial ESCN who underwent ESD or ERFA between January 2015 and December 2021. The primary outcome measure was recurrence-free survival. Results: Ninety-two and 33 patients with superficial ESCN underwent ESD and ERFA, respectively. The en bloc, R0, and curative resection rates for ESD were 100.0%, 90.2%, and 76.1%, respectively. At 12 months, the complete response rate was comparable between the two groups (94.6% vs 90.9%, p=0.748). During a median follow-up of 66 months, recurrence-free survival was significantly longer in the ESD group than in the ERFA group (p=0.004), while no significant differences in overall survival (p=0.845) and disease-specific survival (p=0.494) were observed.Preoperative diagnosis of intramucosal cancer (adjusted hazard ratio, 5.55; vs high-grade intraepithelial neoplasia) was an independent predictor of recurrence. Significantly fewer patients in the ERFA group experienced stenosis compare to ESD group (15.2% vs 38.0%, p=0.016). Conclusions The risk of recurrence was higher for ERFA than ESD for ESCN but overall survival was not affected. The risk of esophageal stenosis was significantly lower for patients who underwent ERFA.

[Objective] To evaluate the clinical application value of intrauterine perfusion with platelet-rich plasma (PRP) combined with in vitro fertilization-frozen-thawed embryo transfer (IVF-FET) in patients with chronic endometritis (CE). [Methods] A randomized controlled trial (RCT) was conducted, enrolling 60 CE patients undergoing artificial cycle frozen embryo transfer at our hospital from January 2022 to January 2024. Participants were randomly divided into three groups: Group A (routine frozen embryo transfer, n=20), Group B (routine frozen embryo transfer + one PRP intrauterine perfusion, n=20), and Group C (routine frozen embryo transfer + two PRP intrauterine perfusions, n=20). Endometrial thickness during the transformation and transplantation phases, uterine artery pulsatility index (PI), resistance index (RI), systolic peak velocity/end-diastolic velocity (S/D) ratio during transplantation, serum levels of IL-2, IL-4, IL-6, IL-10, and TNF-α during transplantation, as well as biochemical pregnancy rate, clinical pregnancy rate, live birth rate, and early miscarriage rate were compared across groups. [Results] No significant differences in endometrial thickness were observed among the three groups during the transformation phase (P>0.05). During the transplantation phase, endometrial thickness in Groups C and B was significantly higher than in Group A[9.54 (8.96-10.22) and 8.90 (8.34-9.72) vs 8.37 (7.89-8.75) mm, P<0.05], with Group C showing greater thickness than Group B (Z=3.733, P<0.05). Endometrial thickness in Groups C and B during transplantation was significantly increased compared to their respective transformation phases (Z=2.191, 2.462; P<0.05). Groups C and B exhibited lower PI, RI, and S/D values than Group A[PI:1.87 (1.77-1.97), 1.94 (1.88-2.15) vs 2.43 (2.35-2.49); RI:0.75 (0.73-0.77), 0.78 (0.75-0.81) vs 0.84 (0.83-0.86); S/D:2.61 (2.33-3.42), 3.01 (2.20-3.93) vs 3.72 (3.06-4.49); P<0.05]. Group C demonstrated lower PI and RI than Group B (P<0.05). IL-2 levels in Groups C and B were higher than in Group A[3.88 (2.71-5.01), 3.59 (2.73-4.38) vs 3.16 (2.11-3.25) ng/L, P<0.05], while IL-4, IL-6, IL-10, and TNF-α levels were significantly lower (IL-4: Z=1.428, 2.421; IL-6: Z=1.754, 2.435; IL-10: Z=1.754, 2.854; TNF-α: Z=1.961, 1.765; P<0.05). Group C had lower IL-6 levels than Group B (Z=3.976, P<0.05). Biochemical pregnancy rate, clinical pregnancy rate, and live birth rate in Group C were significantly higher than in Group A (75% vs 40%, 70% vs 35%, 60% vs 20%, P<0.05). No significant differences in early miscarriage rates were observed among the groups (χ²=3.750, P>0.05). [Conclusion] Intrauterine autologous PRP perfusion in CE patients enhances pregnancy and live birth rates, improves pregnancy outcomes post-FET, and demonstrates superior efficacy in endometrial repair and receptivity with two PRP perfusions compared to a single perfusion. This provides a safe and effective therapeutic option for optimizing outcomes in CE patients with prior implantation failure.

OBJECTIVE To explore the effects of prescription pre-review system on rational drug use and off-label drug use management in outpatient and emergency department. METHODS A retrospective analysis was conducted on outpatient and emergency department prescription data from three phases in our hospital： January to May 2023 （silent review phase， control group）， June to October 2023 （systematic automatic review phase， intervention group 1）， and November 2023 to March 2024 （phase combining systematic automatic review with centralized feedback from pharmacists to physicians regarding irrational prescriptions， intervention group 2）. These phases followed the implementation of our hospital’s pre-prescription review software. Statistical analysis of the prompt rate of alert， rate of irrational prescriptions， registered the off-label drug use rate and false positive irrationality prescription rate were conducted. Meanwhile， the composition of irrational prescriptions was analyzed， and evidence- based evaluation of the off-label drug use proposed by clinicians was also conducted. RESULTS Compared with control group， the prompt rate of alert and the rate of irrational prescriptions in intervention group 1 were all decreased significantly after receiving pop-up notification， with statistically significant differences （P＜0.05）. With the help of system warning and the pharmacists feedback， the prompt rate of alert and the rate of irrational prescriptions declined further in the intervention group 2， but there was no statistically significant difference when compared with intervention group 1 （P＞0.05）. The main type of irrational drug use was improper administration routes. When comparing intervention group 1 with the control group， as well as intervention group 2 with intervention group 1， a significant decrease in the rate of improper administration routes was observed， with statistically significant differences （P＜0.05）. Compared with control group， there was no significant difference in the registered off-label drug use rate of intervention group 1 and intervention group 2 （P＞0.05）. The doctor’s awareness of off-label drug use registration increased due to the real-time alerts from the pre-prescription review software， along with the pharmacists’ regular summarization and feedback. Total 13 items registrations of off-label drug use were proposed by clinicians from June 2023 to March 2024， all of which were supported by evidence of varying levels； among them， 3 items received FDA approval， 4 items were included in the Micromedex database， and the remaining 6 items were supported by evidence from system reviews or randomized controlled trials. CONCLUSIONS Prescription pre-review system can improve the level of rational drug use and assist in the standardized management of off-label drug use.

ObjectiveTo explore the sequential effects of hypoxic exercising on miR-27/PPARγ and lipid metabolism target gene and protein expression levels in the obesity rats’ liver. Methods13-week-old male diet-induced obesity rats were randomly divided into three groups (n＝10): normal oxygen concentration quiet group (N), hypoxia quiet group (H), hypoxic exercise group (HE). Exercise training on the horizontal animal treadmill for 1 h/d, 5 d/week for a total of 4 week, and the intensity of horizontal treadmill training was 20 m/min (hypoxic concentration was 13.6%). Comparison of the weights of perirenal fat and epididymal fat in rats across different groups and calculation of Lee’s index based on body weight and body length of rats in each group were done. And the serum concentrations of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) levels were detected. RT-PCR and Western Blot were used to detect the levels of miR-27, PPARγ, CYP7A1 and CD36. ResultsHypoxic exercise decreased the expression levels of miR-27 in the obese rats’ liver, however, the expression level of PPARγ was gradually increased. The expression levels of miR-27 in HE group were significantly lower than N group (P<0.05). The expression levels of PPARγ mRNA in N group were significantly lower than H group (P<0.05), especially lower than HE group (P<0.01). The protein expression of PPARγ protein in N group was significantly lower than that other groups (P<0.01). The expression of lipid metabolism-related genes and proteins increased in the obese rats’ liver. The expression of CYP7A1 mRNA in N group was significantly lower than H group (P<0.05), especially lower than HE group (P<0.01). The expression of CYP7A1 protein in the obese rats’ liver in N group was extremely lower than H group and HE group (P<0.01). The protein expression of CD36 in N group was significantly lower than that in HE group (P<0.05). Hypoxia exercise improved the related physiological and biochemical indexes of lipid metabolism disorder. The perirenal fat weight of obese rats in HE group was extremely lower than N group and H group (P<0.01), and the perirenal fat weight in N group was significantly higher than H group (P<0.05). The epididymal fat weight in N group was significantly higher than H group (P<0.05), and extremely higher than HE group (P<0.01). The Lee’s index in HE group was extremely lower than N group and H group (P<0.01). The serum concentration of TC in obese rats in HE group was extremely lower than N group and H group (P<0.01). The serum concentration of TG in HE group was extremely lower than N group and H group (P<0.01). The serum concentration of LDL-C in N group was extremely higher than HE group (P<0.01). The serum concentration of HDL-C in N group was extremely lower than H group (P<0.01). ConclusionHypoxia and hypoxia exercise may negatively regulate the levels of PPARγ by inhibiting miR-27 in the obese rats’ liver, thereby affecting the expression of downstream target genes CYP7A1 and CD36, and promoting cholesterol, fatty acid oxidation and HDL-C transport in the liver, and ultimately the lipid levels in obese rats were improved. The effect of hypoxia exercise on improving blood lipid is better than simple hypoxia intervention.

Objective: To investigate the mental health status and related factors among primary and secondary school students in western Yunnan Province, so ao to provide scientific evidences for advancing mental health education. Methods: In June 2024, a stratified cluster sampling method was employed to select 4 584 students from 18 schools across Diqing Tibetan Autonomous Prefecture, Lincang City and Baoshan City three regions in western Yunnan Province. The Mental Health Test (MHT) was used for assessment. Latent class analysis (LCA) and Logistic regression were applied for data classification and related factor analysis respectively. Results: The overall positive detection rate of MHT was 11.81%, with a mean total score of 40.50±19.25. The predominant issues were learning anxiety (58.4%), hypersensitivity tendency (31.1%), and self blame tendency (23.1%). LCA categorized students into four groups:severe psychological problems group (74.4% detection rate), learning anxiety hypersensitivity group ( 16.4 %), learning anxiety physical symptoms group (9.2%), and healthy group (0). Logistic regression revealed that compared with the healthy group, the severe problems group showed higher risks among females ( OR =3.01), junior/senior high school students ( OR =1.88/4.02), and those with authoritarian parenting ( OR =3.54); the anxiety hypersensitivity group had higher risks for females ( OR =1.87), senior high students ( OR =1.54), boarders ( OR =1.31), and authoritarian parenting recipients ( OR = 1.85 ); the anxiety physical symptoms group demonstrated increased risks among females ( OR =2.22), senior high students ( OR =2.58), and authoritarian parenting recipients ( OR =2.74), while lower risks were observed for students with parent/grandparent guardians ( OR =0.38) and non only children ( OR =0.58) (all P <0.05). Conclusions Mental health problems are prominent among students in western Yunnan, with gender, grade level, boarding status, guardian type, and parenting style being key determinants. Recommendations include strengthening mental health education, prioritizing left behind children s psychological well being and promoting healthy development.

Aim To observe the effects of Wenfei Jiangzhuo formula(WFJZF)on rats with vascular de-mentia and investigate its possible mechanism of ac-tion.Methods Thirty-six healthy male SD rats were randomly divided into the sham group,model group,donepezil group,and low-dose,medium-dose and high-dose groups of Wenfei Jiangzhuo formula,with six rats per group.Except for the sham group,the other groups were prepared as VaD models,and each group was gavaged with the corresponding drugs after suc-cessful modeling,and tests were performed after three weeks of treatment.Behavioral,hippocampal CA1 area morphology,neural dendrites and mitochondrial chan-ges were observed in all groups of rats,and phospho-glycerate mutase 5(PGAM5),dynamics-related pro-teins1(Drp1),opticatrophyprotein-1(OPA1),and other proteins were detected in each group.Results Compared with the sham group,rats in the model group and each intervention group had prolonged es-cape latency(P＜0.05),a shorter number of travers-als across the platforms(P＜0.05),a sparse morphol-ogy of hippocampal neurons,a reduction in the number of secondary dendritic spines,and a rupture of the out-er membrane of the mitochondria;the expression of the PGAM5 and Drp1 proteins in hippocampal tissues was elevated(P＜0.05),and the expression of the OPA1 and Mfn1/2 protein expression decreased(P＜0.05);compared with the model group,donepezil group and Wenfei Jiangzhuo formula high-dose group of rats had shorter evasion latency(P＜0.05),increased number of times to traverse the platform(P＜0.05),increased number of hippocampal neurons,tightly packed,more secondary dendritic structures,and reduced mitochon-drial damage;the expression of PGAM5 and Drp1 pro-teins was reduced(P＜0.05),and the expression of OPA1 and Mfn1/2 proteins was elevated(P＜0.05).Conclusions Wenfei Jiangzhuo formula can regulate the PGAM5-Drp1 signaling axis to improve the balance of mitochondrial homeostasis,thus improving the cog-nitive condition of the brain and exerting cerebroprotec-tive effects.

Objective To compare the radiation dose of in vitro pre-fenestration and in situ fenestration thoracic endovascular aortic repair(TEVAR)in treatment of aortic disease.Methods Data of 51 patients with aortic diseases who received in vitro pre-fenestration(group A)and 21 cases who underwent in situ fenestration(group B)TEVAR were retrospectively analyzed.The fluoroscopy duration,total reference air kerma(AK),total dose area product(DAP)and TEVAR time were compared between groups.Results TEVAR was successfully completed in all 72 patients.Fluoroscopy duration([21.42±8.04]min vs.[34.57±9.07]min)and total DAP(44315.0[31157.0,56307.5]μGy·m2 vs.72153.0[45460.0,82354.0]μGy·m2)in group A were both significantly lower than those in group B(both P＜0.05),while total AK(2423[1638,3533]mGy vs.3600[1898,3921]mGy)and TEVAR time([83.41±22.89]min vs.[81.00±22.13]min)in group A were not significant different from those in group B(both P＞0.05).Conclusion Compared with in situ fenestration TEVAR,both the fluoroscopy time and total DAP of in vitro pre-fenestration TEVAR significantly reduced for treating aortic diseases.
