Objective To investigate the clinical efficacy of transurethral plasma electrotomy with rod electrode and end-to-end urethral anastomosis in the treatment of short urethral stricture.Methods 125 male patients with short urethral stricture(＜2 cm)who were admitted to our hospital from January 2014 to December 2020 were retrospectively analyzed.According to different surgical methods,they were divided into transurethral plasma resection with rod electrode(minimally invasive group)and urethral end-to-end anastomosis(open group).According to the length of urethral stricture,the minimally invasive group was divided into minimally invasive group 1(stricture length≤1 cm),minimally invasive group 2(stricture length1-2 cm),open group 1(stricture length ≤1 cm)and open group 2(stricture length 1-2 cm).The four groups were compared with each other,and the surgical success rates were compared between the four groups.Results The success rate of the minimally invasive group 1 and the open group 1 was 88.57％and 93.10％,respectively.There was no significant difference between the two groups(P＞0.05).The surgical success rate of the minimally invasive group 2 and the open group 2 was 67.86％and 90.91％,respectively.The surgical success rate of the minimally invasive group 2 was significantly lower than that of the open group 2.The difference was statistically significant(P＜0.05).The surgical success rate of minimally invasive group 1 and minimally invasive group 2 was 88.57％and 67.86％,respectively,the difference was statistically significant(P＜0.05).The success rate of operation in the open group 1 and the open group 2 was 93.10％and 90.91％,respectively,and there was no significant difference between the two groups(P＞0.05).Conclusion Transurethral plasma resection with rod electrode is preferred for urethral stricture with length≤1 cm,because the success rate of this surgery is the same as that of open surgery,and the surgical trauma is small and the recovery is fast.For 1-2 cm urethral stricture,minimally invasive surgery has less trauma and faster recovery,but open surgery has a higher success rate.The choice of surgical method needs to weigh the advantages and disadvantages and take comprehensive consideration.

Objective:To analyze the influencing factors for efficacy of microvascular decompression (MVD) in primary trigeminal neuralgia (PTN).Methods:A retrospective study was performed. Clinical data of 178 patients with PTN underwent MVD at Department of Neurosurgery, Affiliated Hospital Affiliated to Nantong University from January 2018 to April 2022 were collected. Efficacy was evaluated according to Brisman's criteria. Differences of MVD efficacy in patients with different clinical characteristics or different neurovascular characteristics were compared. Multivariate Logistic regression was used to analyze the independent influencing factors for MVD efficacy.Results:All patients were followed up for about 2 years; at the last follow-up, 164 patients (92.13%) had good postoperative efficacy (130 were cured, 28 were obvious improved, and 6 were improved); 14 patients (7.87%) had poor postoperative efficacy (10 were ineffective and 4 were relapsed). No significant difference in surgical efficacy was noted among patients with different gender, age, left/right lateral pain, disease courses or pain degrees ( P>0.05). Patients with different contact degrees between the trigeminal nerve and blood vessels, different distances between the trigeminal nerve and blood vessels, and different curvature degrees of the posterior trigeminal nerve had significantly different surgical efficacy ( P<0.05). Multivariate Logistic regression indicated that contact degrees between the trigeminal nerve and blood vessels ( OR=0.233, 95% CI: 0.080-0.675, P=0.007), distances between the trigeminal nerve and blood vessels ( OR=6.991, 95% CI: 3.261-14.984, P=0.000), and curvature degrees of the posterior trigeminal nerve ( OR=0.351, 95% CI: 0.158-0.776, P<0.001) were independent influencing factors for postoperative outcomes. Conclusion:The postoperative efficacy is good in patients with slight contact between the trigeminal nerve and blood vessels, with distance between the trigeminal nerve and blood vessels greater than 1×time median width of the trigeminal nerve (WTN), or with hypotenuse height of the arced trigeminal nerve less than 1/2 WTN.

Objective:To investigate the protective effect and possible mechanism of sulforaphane (SFN) on acute liver injury in mice induced by diquat (DQ) poisoning.Methods:Forty-eight male C57BL/6 mice were divided into Control group, DQ model group (DQ group), SFN intervention group (DQ+SFN group), and SFN control group (SFN group) using a random number table method, with 12 mice in each group. Acute liver injury mice model was established by one-time intraperitoneal injection of 1 mL of 40 mg/kg DQ solution at once. SFN group was injected with 1 mL of ddH 2O. After 4 hours of molding, 0.5 mL of 5 mg/kg SFN solution was injected into the peritoneal cavity of the DQ+SFN group and SFN group, once daily for 7 consecutive days. DQ group and Control group were injected with an equal amount of ddH 2O. Then, the mice were euthanized to collect liver tissue and blood samples, and the levels of plasma biomarkers alanine aminotransferase (ALT) and aspartate aminotransferase (AST), as well as oxidative stress indicators such as superoxide dismutase (SOD), glutathione (GSH), and malondialdehyde (MDA) in liver tissue were measured. The changes of liver structure were observed under transmission electron microscopy. The apoptosis and reactive oxygen species (ROS) level in liver tissue were observed under fluorescence microscope. Western blotting was used to detect the protein expressions of nuclear factor E2-related factor 2 (Nrf2), hemeoxygenase-1 (HO-1), Kelch-like ECH-associated protein 1 (Keap1), and cleaved caspase-9 in liver tissue. Results:Compared with the Control group, the liver mitochondria in the DQ group showed severe swelling, partial dissolution of the matrix, and cristae rupture and loss; the levels of plasma AST and ALT significantly increased, the MDA content in the liver increased, the activities of SOD and GSH decreased, the level of ROS significantly increased, the number of apoptotic cells in the liver significantly increased, the protein expressions of Nrf2 and HO-1 significantly decreased, and the protein expressions of Keap1 and cleaved caspase-9 significantly increased. Compared with the DQ group, the mitochondrial damage in the DQ+SFN group was reduced, the levels of plasma AST and ALT were significantly reduced [ALT (U/L): 58.22±4.39 vs. 79.94±3.32, AST (U/L): 177.64±8.40 vs. 219.62±11.60, both P < 0.01], the liver MDA content decreased, and the activities of SOD and GSH increased [MDA (μmol/g: 5.63±0.18 vs. 5.96±0.29, SOD (kU/g): 102.05±4.01 vs. 84.34±5.34, GSH (mmol/g): 16.32±1.40 vs. 13.12±1.84, all P < 0.05], the production of ROS in liver tissue was significantly reduced [ROS (fluorescence intensity): 115.90±10.89 vs. 190.70±10.16, P < 0.05], and apoptotic cells were significantly reduced (cell apoptosis index: 4.39±1.00 vs. 10.71±0.56, P < 0.01), the protein expressions of Nrf2 and HO-1 were significantly increased, while the protein expressions of Keap1 and cleaved caspase-9 were significantly decreased (Nrf2/β-actin: 1.15±0.04 vs. 0.93±0.05, HO-1/β-actin: 1.75±0.12 vs. 0.78±0.04, Keap1/β-actin: 1.00±0.14 vs. 1.28±0.13, cleaved caspase-9/β-actin: 1.31±0.12 vs. 1.81±0.09, all P < 0.05). However, there was no statistically significant difference in various indicators between the SFN group and the Control group. Conclusion:SFN can activate the Keap1/Nrf2 signaling pathway to alleviate DQ induced acute liver injury in mice.

OBJECTIVES: In light of the rise in the global aging population, this study investigated the potential of the oxidative balance score (OBS) as an indicator of phenotypic age acceleration (PhenoAgeAccel) to better understand and potentially slow down aging. METHODS: Utilizing data from the National Health and Nutrition Examination Survey collected between 2001 and 2010, including 13,142 United States adults (48.7% female and 51.2% male) aged 20 and above, OBS and PhenoAgeAccel were calculated. Weighted generalized linear regression models were employed to explore the associations between OBS and PhenoAgeAccel, including a sex-specific analysis. RESULTS: The OBS demonstrated significant variability across various demographic and health-related factors. There was a clear negative correlation observed between the higher OBS quartiles and PhenoAgeAccel, which presented sex-specific results: the negative association between OBS and PhenoAgeAccel was more pronounced in male than in female. An analysis using restricted cubic splines revealed no significant non-linear relationships. Interaction effects were noted solely in the context of sex and hyperlipidemia. CONCLUSIONS A higher OBS was significantly associated with a slower aging process, as measured by lower PhenoAgeAccel. These findings underscore the importance of OBS as a biomarker in the study of aging and point to sex and hyperlipidemia as variables that may affect this association. Additional research is required to confirm these results and to investigate the biological underpinnings of this relationship.

In terms of alternative suggestion, 70.74%(162/229) of surgeons believed that it was necessary for the We-Media platforms to involve more doctors of different specialties, but 40.61%(93/229) of surgeons believed that relevant departments or associations should strengthen supervision under the current situation. In addition, 32.75%(75/229) of surgeons believed that the operation of We-Media platform requires more investment. The were 27.95%(64/229) of surgeons giving specific suggestions on running We-Media platforms, 7.81%(5/64) of which did not suggest a blind try.Conclusions:Most surgeons who open and operate We-Media platforms in China are faced with problems such as busy work, limited time and energy, low-income increase, and lack of professional promotion and maintenance teams and external support. Even so, there are still many surgeons who have achieved success through long-term persistence and high-quality content output, thus increasing the number of patient visits, improving their own ability and industry influence, and bringing a greater sense of professional achievement.

Objective: To investigate the coverage of rotavirus vaccination among children under five years in Xiuzhou District of Jiaxing City, so as to provide insights into rotaviral diarrhea control. Methods: The rotavirus vaccination data of children aged two months to five years were extracted from the vaccination clinics of eight township hospitals and community health service centers through the Zhejiang vaccination information system. The coverage of rotavirus vaccination was analyzed among children with different genders, ages, types of vaccines and doses of vaccination. Results: Totally 32 752 children were included, and the coverage of rotavirus vaccination was 47.09%. The coverage of rotavirus vaccination was significantly higher in boys than in girls ( 47.65% vs. 46.46%, P<0.05 ), and a higher vaccination rate was seen in children with local household registration than in those without ( 56.76% vs. 38.75%, P<0.05 ). The vaccination rates of monovalent and pentavalent rotavirus vaccines were 36.90% and 10.18%, respectively. Totally 26 982 doses of rotavirus vaccines were vaccinated, with a mean dose of ( 0.84±1.02 ) per capita, and the vaccination rates of one, two and three doses were 20.75%, 17.37% and 8.96%, respectively. The median age was 6.00 months ( interquartile range, 3.00 months ) among children vaccinated with the first dose. Conclusions The coverage of rotavirus vaccination and full-dose vaccination are low among children under five in Xiuzhou District, with monovalent rotavirus vaccines predominant. Intensified rotavirus vaccination is therefore recommended.

OBJECTIVE: To predict and verify the target gene of miR-200c-3p and evaluate the inhibitory effect of miR-200c-3p on the proliferation of nephroblastoma cells. METHODS: The putative target genes of miR-200c-3p were predicted by bioinformatics approach. Nephroblastoma cell models with miR-200c-3p overexpression or knockdown were established in SK-NEP-1 and G401 cells with corresponding control groups. The expressions of CCNE2 in SK-NEP-1 and G401 cells in different groups were detected by RT-PCR and Western blotting. A luciferase reporter assay was used to determine the targeting relationship between miR-200c-3p and CCNE2. The effects of miR-200c-3p overexpression or knockdown on cell proliferation was detected by cell counting kit-8 (CCK-8) assay and soft agarose assay. RESULTS: CCNE2 was one of the target genes of miR-200c-3p as predicted by bioinformatics methods. Transfection of the two nephroblastoma cell lines with miR-200c-3p mimic resulted in significantly lowered CCNE2 mRNA and protein expressions ( < 0.05). The results of dual-luciferase assay confirmed that miR-200c-3p bound to the 3'UTR of CCNE2. CCK-8 assay and soft agarose assay demonstrated that overexpression of miR-200c-3p significantly inhibited the proliferation of the nephroblastoma cells ( < 0.01), and knocking down miR-200c-3p in the cells produced the opposite effects. CONCLUSIONS miR-200c-3p overexpression inhibits the proliferation of nephroblastoma cells by down-regulating its target gene CCNE2.
