[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

[Objective] To evaluate the efficacy and safety of sacral neuromodulation (SNM) in the treatment of patients with benign prostatic hyperplasia (BPH) complicated with underactive bladder (UAB) who respond poorly to transurethral resection of the prostate (TURP). [Methods] A retrospective analysis was performed on 10 patients with BPH and UAB treated with TURP by the same surgeon in Zhongda Hospital Southeast University during Jan.2018 and Jan.2023.The residual urine volume was not significantly relieved after operation, and the maximum urine flow rate and urine volume per discharge were not significantly improved.All patients underwent phase I SNM, and urinary diaries were recorded before and after surgery to observe the average daily frequency of urination, volume per urination, maximum urine flow rate, and residual urine volume. [Results] The operation time was (97.6±11.2) min.During the postoperative test of 2-4 weeks, if the residual urine volume reduction by more than 50% was deemed as effective, SNM was effective in 6 patients (60.0%). Compared with preoperative results, the daily frequency of urination [(20.2±3.8) times vs. (13.2±3.2) times], volume per urination [(119.2±56.7) mL vs. (246.5±59.2) mL], maximum urine flow rate [(8.7±1.5) mL/s vs. (16.5±2.6) mL/s], and residual urine volume [(222.5±55.0) mL vs. (80.8±16.0) mL] were significantly improved, with statistical significance (P<0.05). There were no complications such as bleeding, infection, fever or pain.The 6 patients who had effective outcomes successfully completed phase II surgery, and the fistula was removed.During the follow-up of 1 year, the curative effect was stable, and there were no complications such as electrode displacement, incision infection, or pain in the irritation sites.The residual urine volume of the other 4 unsuccessful patients did not improve significantly, and the electrodes were removed and the vesicostomy tube was retained. [Conclusion] SNM is safe and effective in the treatment of BPH with UAB patients with poor curative effects after TURP.

ObjectiveTo explore the correlation between general anesthesia and mild cognitive impairment in older adults so as to provide new ideas for early prevention and timely intervention of mild cognitive impairment(MCI). MethodsBased on the baseline survey of the Hubei memory and aging cohort study(2018-2023), the participants completed a thorough neuropsychological assessment and physical examination, and self-reported a history of general anesthesia and surgery. The association of general anesthesia and MCI in the elderly was analyzed using the logistic regression model. In addition, the stratification and interaction analysis of anesthesia history, anesthesia number and physical intellectual exercise were conducted separately. ResultsA total of 5 069 older adults aged 65 and above were included in this study, including 3 692 city dwellers and 1 377 rural people, among whom were 2 584 women (51%). Out of the 1 472 participants with history of general anesthesia, 249 people (17.4%) had MCI. After controlling for confounding factors, there was a 39.6% increased risk of MCI in older adults who underwent general anesthesia [OR=1.396,95%CI(1.169,1.668),P<0.001], suggesting that general anesthesia may be an independent influence on MCI. For the older adults who had one general anesthesia [OR=1.235,95%CI(1.001,1.523),P=0.049], two general anesthesia [OR=1.779,95%CI (1.292,2.450),P<0.001], and three OR more general anesthesia [OR=2.395,95%CI (1.589,3.610),P<0.001], their risks of MCI were increased by 23.5%, 77.9%, and 139.5%, respectively. Compared with the older adults without a history of general anesthesia who did not exercise, the risk of developing MCI was significantly negatively correlated with the exercise group, cognitive exercise group, and combined exercise and cognitive exercise groups (all P<0.001). The risk of developing MCI in the exercise group was 60.2% of that in the no exercise group [OR = 0.602, 95% CI(0.456, 0.795)], the risk in the cognitive exercise group was 42.4% of that in the no exercise group [OR = 0.424, 95% CI(0.294, 0.613)], and the risk in the combined exercise and cognitive exercise group was 27.0% of that in the no exercise group [OR = 0.270, 95% CI (0.208, 0.353)]. In the older adults with a history of general anesthesia, compared with the no exercise group, the risk of developing MCI was significantly negatively correlated with the cognitive exercise group and the combined exercise and cognitive exercise group (all P < 0.05). The risk of developing MCI in the cognitive exercise group was 47.7% of that in the no exercise group [OR=0.477, 95% CI (0.256,0.892)], the risk in the combined exercise and cognitive exercise group was 34.5% of that in the no exercise group [OR=0.345, 95% CI (0.220, 0.540)], while the risk in the exercise-only group did not show a significant difference. ConclusionThe risk of MCI increased significantly in older adults with a history of general anesthesia, and this risk increased with the times of anesthesia. Physical and mental exercise reduces the risk of MCI. it is recommended that older adults with a history of anesthesia incorporate physical and mental exercise into their daily lives to prevent mild cognitive impairment.

ObjectiveTo evaluate pharmacological effects of Shengmai injection(SMI)on cerebral ischemia and study its neuroprotective mechanism. MethodsMale specific pathogen-free (SPF) Sprague-Dawley (SD) rats were randomly divided into a sham group, a model group, a low-dose SMI group(3 mL·kg-1), a middle-dose SMI group(6 mL·kg-1), a high-dose SMI group(12 mL·kg-1), and a Ginaton group(4 mL·kg-1)according to the random number table method, with 12 rats in each group. The rat model of cerebral ischemia-reperfusion(MCAO/R)was prepared via the suture method. The administration groups were intraperitoneally injected with corresponding concentrations of SMI or Ginaton injection after reperfusion, which was conducted for 3 consecutive days. The sham group and model group were administered the equivalent volume of physiological saline. The pharmacological effects of SMI on brain injury in MCAO/R rats were evaluated by neurological function scores, cerebral infarction area, hematoxylin-eosin (HE) staining, Nissl staining, terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining, and Western blot. The dominant link and key protein of SMI treating cerebral injury were explored using proteomic analysis. The related mechanisms of SMI were further validated using enzyme-linked immunosorbent assay (ELISA), Western blot, and chloride ion fluorescence probe with oxygen-glucose deprivation/reoxygenation(OGD/R)-treated PC12 cells and MCAO/R rats. ResultsCompared with the sham group, the model group showed significantly increased neurological function scores, cerebral infarction area, neuronal apoptosis rate, and expression levels of apoptosis related proteins (P<0.05, P<0.01)and significantly decreased density of Nissl bodies and neurons(P<0.01). Compared with the model group, the SMI groups exhibited significantly decreased neurological function scores, cerebral infarction area, neuronal apoptosis rate, and expression levels of apoptosis related proteins (P<0.05, P<0.01)and significantly increased density of Nissl bodies and neurons (P<0.05). The proteomic analysis results showed that oxidative stress and inflammatory response were important processes of SMI intervening in MCAO/R injury, and the chloride intracellular channel protein 1 (CLIC1) was one of key proteins in its action network. The levels of representative indicators of oxidative stress and inflammatory response in the MCAO/R rats of the SMI groups were significantly reduced, compared with those in the model group(P<0.05, P<0.01), and the expression levels of CLIC1 and downstream NOD-like receptor protein 3 (NLRP3) decreased (P<0.01). In addition, the experimental results based on the OGD/R PC12 cells showed that SMI significantly increased the cell survival rate(P<0.01) and significantly decreased the intracellular chloride ion concentration(P<0.05). ConclusionSMI has neuroprotective effects. Oxidative stress and inflammatory response are key processes of SMI intervening in MCAO/R injury. The potential mechanism is closely related to the regulation of CLIC1.

BackgroundStudents in secondary vocational health school are at the age of puberty and prone to depressive symptoms. Peer victimization and social media addiction are found to be crucial in influencing the development of depression, and positive mental health has been proven to alleviate depressive symptoms, whereas there remains a striking lack of research on the mediating role of positive mental health and social media addiction in the relationship between peer victimization and depressive symptoms among secondary vocational health school students. ObjectiveTo explore the relationship between peer victimization and depressive symptoms and investigate the mediating role of positive mental health and social media addiction, so as to provide references for the prevention of depression among secondary vocational health school students. MethodsFrom October to December 2020, a cluster sampling framework was utilized to recruit 7 307 students from a secondary vocational health school in Luzhou City, Sichuan Province. Assessments were performed using Multidimensional Peer Victimization Scale (MPVS), Warwick-Edinburgh Mental Well-being Scale (WEMWBS), Bergen Social Media Addiction Scale (BSMAS) and Patient Health Questionnaire Depression Scale-9 item (PHQ-9). Spearman correlation analysis was calculated to determine correlations between scores of scales, Process 4.0 was employed to test the mediation effect, and the bias-corrected Bootstrap procedure was used to test the significance of the mediation effect. ResultsA total of 7 044 (96.40%) valid questionnaires were collected. And 4 391(62.34%)students were found to have depressive symptoms. Correlation analysis revealed that PHQ-9 score was positively correlated with BSMAS score and MPVS score (r=0.404, 0.506, P<0.01). WEMWBS score was negatively correlated with PHQ-9 score, BSMAS score and MPVS score (r=-0.587, -0.259, -0.358, P<0.01). BSMAS score was positively correlated with MPVS score (r=0.328, P<0.01). Positive mental health played a mediating role in the relationship between peer victimization and depressive symptoms, with an indirect effect value of 0.130 (95% CI: 0.119~0.141), accounting for 30.81% of the total effect. Social media addiction also mediated the relationship between peer victimization and depressive symptoms, with an indirect effect value of 0.052 (95% CI: 0.045~0.059), accounting for 12.34% of the total effect. Positive mental health and social media addiction exhibited a chained mediation effect on the relationship between peer victimization and depressive symptoms, with an indirect effect value of 0.012 (95% CI: 0.010~0.014) and accounting for 2.84% of the total effect. ConclusionPeer victimization can affect the presence of depressive symptoms among secondary vocational health school students both directly and indirectly through either separate or chained mediation of positive mental health and social media addiction.

Background Arsenic is an environmentally harmful substance that causes hepatic insulin resistance and liver damage, increasing the risk of type 2 diabetes mellitus. Objective To explore whether the insulin-like growth factor 2 mRNA binding protein 2 (IGF2BP2) is involved in insulin resistance in HepG2 cells after arsenic exposure through the peroxisome-proliferator-activated receptor γ (PPAR-γ) / glucose transporter 4 (GLUT4) pathway. Methods Cell viability was determined using cell counting kit 8 (CCK8) and an appropriate NaAsO2 infection dose was determined. A cellular arsenic exposure model of HepG2 cells was established by four concentrations of NaAsO2 solution for 24 h (the experiment was divided into four groups: 0, 2, 4, and 8 μmol·L−1); HepG2 cells were firstly treated with pcDNA3.1-IGF2BP2 and pcDNA3.1-NC respectively for 6 h, then with 8 μmol·L−1 NaAsO2 for 24 h to establish a IGF2BP2 overexpression cell model (the experiment was divided into 4 groups: control, NaAsO2, NaAsO2+pcDNA3.1-IGF2BP2, and NaAsO2+pcDNA3.1-NC); finally the cells were subject to 100 nmol·L−1 insulin stimulation for 30 min. Glycogen and glucose in HepG2 cells were determined by glycogen and glucose assay kits; mRNA expression levels of IGF2BP2 were measured by quantitative real-time PCR; protein expression levels of IGF2BP2, PPAR-γ, and GLUT4 in HepG2 were detected by Western blot (WB); and the binding of IGF2BP2 to PPAR-γ and PPAR-γ to GLUT4 was verified by co-immunoprecipitation (CO-IP) experiment. Results The results of CCK8 experiment showed a dose-effect relationship between NaAsO2 concentration and cell viability. When the concentration of NaAsO2 was ≥4 μmol·L−1 , the cell viabilities were lower than that of the control group (P <0.05). With the increasing dose of NaAsO2 infection, reduced glucose consumption and glycogen levels in HepG2 cells were found in the 2, 4, and 8 μmol·L−1 NaAsO2 treatment groups compared to the control group (P <0.05). The difference between the mRNA expression level of IGF2BP2 in the HepG2 cells treated with 4 or 8 μmol L−1 NaAsO2 and the control group was significant (P <0.05). In the IGF2BP2 overexpression cell model, compared with the control group, glucose consumption and glycogen levels were lowered in the NaAsO2 group (P <0.05), the mRNA expression level of IGF2BP2 and the protein expression levels of IGF2BP2, PPAR-γ, and GLUT4 in the cell membrane were all decreased (P <0.05). Compared with the NaAsO2 group, the glucose consumption and glycogen levels were increased in the NaAsO2+pcDNA3.1-IGF2BP2 group (P <0.05), and the mRNA expression level of IGF2BP2 and the protein expression levels of IGF2BP2, PPAR-γ, and GLUT4 in the cell membrane were all increased (P <0.05). The results of CO-IP experiments showed that IGF2BP2 interacted with PPAR-γ as well as PPAR-γ with GLUT4 protein. Conclusion IGF2BP2 is involved in arsenic exposure-induced insulin resistance in HepG2 cells by acting on the PPAR-γ/GLUT4 pathway.

ObjectiveTo unveil the mechanism of Jianpi Huogu prescription (JPHGP) in ameliorating the dyslipidemia of steroid-induced osteonecrosis of the femur head (SONFH) by oxylipidomics combined with transcriptomics. MethodsSixty SD rats were assigned into normal, model, low-, medium-, and high-dose (2.5, 5, 10 g·kg-1, respectively) JPHGP, and Jiangushengwan (1.53 g·kg-1) groups. Lipopolysaccharide was injected into the tail vein at a dose of 20 μg·kg-1 on days 1 and 2, and methylprednisolone sodium succinate was injected at a dose of 40 mg·kg-1 into the buttock muscle on days 3 to 5. The normal group received an equal volume of normal saline. Drug administration by gavage began 4 weeks after the last injection, and samples were taken after administration for 8 weeks. Hematoxylin-eosin staining was conducted to reveal the histopathological changes of the femoral head, and the number of adipocytes, the rate of empty bone lacunae, and the trabecular area were calculated. Micro-computed tomography was used for revealing the histological and histomorphometrical changes of the femoral head. Enzyme-linked immunosorbent assay was employed to measure the serum levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB). At the same time, the femoral head was collected for oxylipidomic and transcriptomic detection. The differential metabolites and differential genes were enriched and analyzed, and the target genes regulating lipid metabolism were predicted. The predicted target proteins were further verified by molecular docking, immunohistochemistry, and Western blot. ResultsCompared with the normal group, the model group showcased thinning of the femoral head, trabecular fracture, karyopyknosis, subchondral cystic degeneration, increases in the number of adipocytes and the rate of empty bone lacunae (P<0.01), a reduction in the trabecular area (P<0.01), decreases in BMD, Tb.Th, Tb.N, and BV/TV, and increases in Tb.Sp and BS/BV (P<0.01). Compared with the model group, the JPHGP groups showed no obvious thinning of the femoral head or subchondroidal cystic degeneration. The high- and medium-dose JPHGP groups presented declines in the number of adipocytes and the rate of empty bone lacunae, an increase in the trabecular area (P<0.05, P<0.01), rises in BMD, Tb.Th, Tb.N, and BV/TV, and decreases in Tb.Sp and BS/BV (P<0.05, P<0.01). Compared with the normal group, the model group showcased raised serum levels of TG, TC, LDL, and ApoB and lowered serum levels of HDL and ApoA1 (P<0.01). Compared with the model group, the JPHGP groups had lowered serum levels of TG, TC, LDL, and ApoB (P<0.05, P<0.01) and a risen serum level of ApoA1 (P<0.05, P<0.01). Moreover, the serum level of HDL in the high-dose JPHGP group increased (P<0.01). A total of 19 different metabolites of disease set and drug set were screened out by oxylipidomics of the femoral head, and 119 core genes with restored expression were detected by transcriptomics. The enriched pathways were mainly concentrated in inflammation, lipids, apoptosis, and osteoclast differentiation. Molecular docking, immunohistochemistry, and Western blot results showed that compared with the normal group, the model group displayed increased content of 5-lipoxygenase (5-LO) and peroxisome proliferator-activated receptor γ (PPARγ) in the femoral head (P<0.01). Compared with the model group, medium- and high-dose JPHGP reduced the content of 5-LO and PPARγ (P<0.05, P<0.01). ConclusionJPHGP can restore the levels of oxidized lipid metabolites by regulating the 5-LO-PPARγ axis to treat SONFH in rats. Relevant studies provide experimental evidence for the efficacy mechanism of JPHGP in the treatment of SONFH.

AIM: To explore the effects of preoperative anterior segment parameters on the rotational stability of Toric intraocular lens(Toric IOL).METHODS:Prospective study. A total of 41 cataract patients(54 eyes)with combined corneal regular astigmatism from March to December 2023 were included and treated with cataract phacoemulsification combined with plate loop Toric IOL implantation in the Department of Ophthalmology of the First Affiliated Hospital of Zhengzhou University. The rotation degree of Toric IOL and uncorrected distance visual acuity(UCDVA)were evaluated at 1 d, 2 wk, and 1 mo postoperatively, the corrected distance visual acuity(CDVA)was evaluated at 2 wk and 1 mo after surgery, and the decentration and tilt of the Toric IOL were assessed at 2 wk postoperatively.RESULTS:A total of 33 patients(40 eyes)were included in this study. The UCDVA(LogMAR)of 1 d, 2 wk and 1 mo postoperatively were 0.10(0.10, 0.30), 0.05(0, 0.10)and 0(0, 0.10), respectively, which was improved compared with the preoperative levels of [0.80(0.49, 1.00)](P<0.001). The CDVA(LogMAR)of 2 wk and 1 mo postoperatively were 0.05(0, 0.15)and 0(0, 0.138), respectively, which was improved compared with preoperative levels of [0.52(0.40, 0.80)](P<0.001). The residual astigmatism of 2 wk and 1 mo postoperatively were 0.625(0.25, 0.75)D and 0.50(0.25, 0.75)D, respectively, which was significantly reduced compared with preoperative astigmatism of [1.82(1.31, 2.59)D](P<0.001). The preoperative anterior segment length(ASL), and lens thickness(LT)were positively correlated with Toric IOL rotation degree at 1 d(rs=0.463, P=0.003; rs=0.340, P=0.032)and 2 wk(rs=0.520, P=0.001; rs=0.409, P=0.009)postoperatively. At 1 mo postoperatively, only ASL was positively correlated with Toric IOL rotation degree(rs=0.463, P=0.003). The results of linear regression analysis showed that preoperative ASL was a predictor of rotation degree at 1 d, 2 wk and 1 mo after surgery(F1 d=10.098, P1 d=0.003; F2 wk=16.915, P2 wk<0.001; F1 mo=10.957, P1 mo=0.002). The rotation degree of Toric IOL was positively correlated with lens decentration(rs=0.360, P=0.043).CONCLUSION:The early postoperative rotation of Toric IOL is positively correlated with ASL, and the rotation is also positively correlated with lens decentration.
