Objective To explore the correlation between triglyceride-glucose(TyG)index and hyperuricemia in men with normal fasting blood glucose(FPG)levels.Methods A total of 309 men with normal FPG who participated in a health examination at the Ninth Medical Center of the People's Liberation Army General Hospital in April 2024 were enrolled in this study.All the subjects were divided into the normal uric acid(NUA,n=218)group and the hyperuricemia(HUA,n=91)group according to serum uric acid(SUA)levels.Results Scr,TG,weight,SBP,DBP,BMI,ALT,AST,γ-GGT,and TyG index were higher in the HUA group than in the NUA group(P<0.05).Pearson and Spearman correlation analysis showed that SUA were positively correlated with Scr,eGFR,TG,weight,SBP,DBP,BMI,ALT,AST,γ-GGT and TyG(P<0.05),and negatively correlated with HDL-C(P<0.05).Logistic regression analysis showed that after adjusting for confounding factors,TyG index remained an important influencing factor for HUA.ROC curve analysis showed that the area under the ROC curve of TyG index predicting hyperuricemia in men with normal FPG was 0.665,with an cutoff value of 8.45.Conclusions TyG index in men with normal FPG are influencing factors for hyperuricemia,indicating that hyperuricemia has a close association with insulin resistance,and is an important component of metabolic syndrome.

Objective:To investigate the clinicopathological features including immunophenotype, molecular characteristics, differential diagnosis and prognosis of SMARCB1-deficient renal medullary carcinoma (RMC) without sickle cell trait.Methods:The clinicopathological data of 12 cases of SMARCB1-deficient RMC without sickle cell trait were collected from 7 domestic institutions during the period of 2015 to 2024. Their clinical characteristics, morphological features and immunohistochemical properties were observed and analyzed. High-throughput DNA-targeted next-generation sequencing was performed, and follow-up data were gathered along with relevant literature review.Results:Among the 12 patients, 5 were female and 7 were male. The patients age ranged from 27 to 84 years with a median age of 58.5 (46.0, 71.0) years. None of them had sickle cell disease or other hemoglobinopathies. Eight cases occurred in the left kidney and 4 cases were located in the right kidney. The average maximum diameter of the tumor was 6.1 (4.0,7.5) cm, with a range of 2.0 to 14.9 cm (the median maximum diameter 5.5 cm). Histologically, the tumors showed poorly differentiated adenocarcinoma, arranged in solid and tubular patterns. Papillary structure was noted in 5 cases, cribriform structure in 3 cases, rhabdoid differentiation in 3 cases, and sarcomatoid differentiation in 2 cases. Inflammatory desmoplastic stromal reaction was observed in 8 cases, among which stromal myxoid degeneration was seen in 6 cases. Tumor necrosis was apparent in 6 cases. The tumor cells had abundant eosinophilic or clear cytoplasm and prominent nucleoli. The nuclear grading was grade 3 or 4 according to the International Society of Urological Pathology (ISUP). Immunohistochemical staining showed that the tumor cells of all 12 cases expressed PAX8 and loss of SMARCB1/INI1 protein expression, and 5 of 10 cases expressed OCT3/4. Seven samples had valid archived paraffin tissues for high-throughput DNA-targeted next-generation sequencing. The results showed that all 7 cases had pathogenic mutations in the SMARCB1 gene. The mutation sites included exon5 c.595A>T (p.K199*), exon2 c.200_207del (p.S67*), exon2 p.G69VfsTer16, exon7 c.986G>T (p.S329I), exon7 c.886A>T (p.K296*), exon6 c.635T>A (p.L212*), exon5 c.577del (p.M193Wfs16), and exon6 c.784del (p.V262Sfs5). Follow-up data were obtained for 6 of 12 patients. Among them, 1 patient had lung and bone metastases, 1 patient had liver and bone metastases and 1 patient had multiple bone metastases at the time of diagnosis; 1 patient had bone metastases 5 months after surgery. One patient died of postoperative complications 10 days after surgery, 4 patients died of tumors (the survival time ranged from 4 to 8 months), and 1 patient had no recurrence or metastasis during the 8-month follow-up after surgery.Conclusions:SMARCB1-deficient RMC without sickle cell trait is a highly aggressive and poorly differentiated renal cell carcinoma. It has similar histomorphology, immunophenotype, molecular characteristics and prognosis to RMC, which further supports that it is a sporadic subtype of RMC related to sickle cell trait.

Objective To evaluate the molluscicidal effect of spraying different formulations of niclosamide ethanolamine salt with drones against Oncomelania hupensis in ditches. Methods A semi-dry and semi-wet ditch with O. hupensis snails was selected in the second branch field of Jiangbei Farm, Jiangling County, Hubei Province in May 2023, and divided into 4 experimental areas, named groups A1, A2, B1 and B2. Environmental cleaning was performed in groups A1 and B2, and was not conducted in groups A2 or B2. Then, 50% wettable powder of niclosamide ethanolamine salt was sprayed with drones at an effective dose of 2 g/m² in groups A1 and A2, and 5% niclosamide ethanolamine salt granule was sprayed with drones at an effective dose of 2 g/m² in groups B1 and B2. O. hupensis snails were surveyed using the systematic sampling method 1, 3, 5, 7, 14 days after spraying, and the natural mortality and corrected mortality of O. hupensis snails were calculated. Results The occurrence of frames with living snails, mean density of living snails and natural mortality of snails were 97.50% (117/120), 6.30 snails/0.1 m² and 1.18% (9/765) in the test ditch before spraying, respectively. There were significant differences in the mortality of snails among four groups 1, 3, 5, 7 and 14 days after spraying niclosamide formulations with drones (χ² = 17.230, 51.707, 65.184, 204.050 and 34.435, all P values < 0.01). The overall mortality rates of snails were 94.51% (1 051/1 112), 79.44% (908/1 143), 96.54% (977/1 012) and 88.55% (1 021/1 153) in groups A1, A2, B1 and B2 (χ² = 207.773, P < 0.05), respectively. In addition, there was no significant difference in the overall snail mortality between groups A1 and B1 (P > 0.05), and the snail mortality in groups A1 and B1 were both statistically different from that in groups A2 and B2 (all P values < 0.05). Conclusion Both 50% wettlable powder of niclosamide ethanolamine salt and 5% niclosamide ethanolamine salt granule sprayed with drones are active against O. hupensis snails in ditches, and environmental cleaning may improve the molluscicidal effect.

Objective To investigate the inhibitory effect of cryptotanshinone (CPT) on human breast cancer cell MCF7 and its mechanism. Methods The survival rate of MCF7 cells was measured by MTT assay. Cell apoptosis was detected by Annexin V/PI assay and Hoechst 33258 fluorescence staining assay. Cell cycle and reactive oxygen species were detected by flow cytometry. Cell migration and invasion were detected by cell scratch test and Transwell chamber test. The surface molecules CD44 and CD24 were detected by flow cytometry and microsphere culture. The expression of cell-associated proteins was detected by Western blot. Results CPT inhibited the proliferation of MCF7 cells in a dose-dependent manner, and the 24 h IC₅₀ value was 19.24 μmol/L. Compared with the untreated group, the CPT-treated group showed cell cycle arrested in the S phase, and apoptosis was induced. The results of the cell scratch and Transwell chamber tests showed that CPT significantly inhibited the migration and invasion of MCF7 cells. Furthermore, CPT reduced the CD24^-/LowCD44⁺ cell population in MCF7 cell-derived microspheres. Western blot results showed that CPT could up-regulate the expression of Bax protein, down-regulate the expression of BCL-2, PI3K-p85, Akt, N-cadherin, Twist1, Sox2, Oct4, and Nanog protein, effectively inhibit the phosphorylation of ER-α, and decrease the expression of ABCG2. Conclusion CPT can inhibit the proliferation of MCF7 cells by inhibiting the migration and invasion of MCF7 cells, decreasing the number of CD24^-/lowCD44⁺ cells and affecting the expression of tumor stem cell-related proteins.

Objective To investigate the incidence and risk factors of neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture. Methods Live born infants, including those diagnosed with neonatal asphyxia, were recruited from 16 different hospitals in Hubei Enshi Tujia and Miao Autonomous Prefecture from January to December of 2016. The 16 hospitals included four grade A tertiary hospitals (three general hospitals and one traditional Chinese medicine hospital) and 12 grade A secondary hospitals (eight general hospitals, one maternal and child health hospital and three traditional Chinese medicine hospitals). A retrospective investigation was conducted using questionnaire to analyze the basic information, perinatal risk factors and prognosis of those infants. Chi-square test was used for statistical analysis. Results Among 22 294 recruited live born infants, 733 (3.29%) were diagnosed with neonatal asphyxia on discharge, including 627 (85.54%) mild cases and 106 (14.46%) severe cases. And neonatal asphyxia resulted in deaths of 27 cases (3.68%). The risk factors for neonatal asphyxia included multiple pregnancy, pregnancy conceived with assisted reproductive technology, premature infant, low birth weight infant, fetal malposition, congenital malformation, male infant, born during transfer, mother of Tujia nationality, low educational level (primary school or lower), living in rural area, the number of antenatal visits ≤3, history of early threatened abortion, anemia in pregnancy, hypertensive disorders of pregnancy, chorioamnionitis, abnormal pregnancy history and abnormality of umbilical cord, amniotic fluid or placenta. Conclusions The incidence of neonatal asphyxia in Enshi area is obviously higher than the national average. The main risk factors for neonatal asphyxia in this area are related to maternal background and the living condition of the mother during pregnancy, delivery as well as the newborn at birth.

The Back-Shu points of the five Zang-organs are a group of points where qi and blood pour into the back and lumbar regions. Acupuncture at these points has a wide indication scope. However, it’s reported that internal organs were punctured in some cases because of improper control of needling depth, angle, and intensity during acupuncture. We used perpendicular needling instead of conventional oblique needling during the acupuncture of the Back-Shu points of the five Zang-organs. We found that when patients were completely relaxed, acupoints were correctly selected, the needling depth, the way of holding the needle, and inserting methods were well controlled, perpendicular needling of the Back-Shu points of the five Zang-organs can produce stronger needling sensation, and it’s easier to operate, safer, and more effective compared to oblique needling.

Objective To evaluate the nutritional status of elderly patients with cardiovascular by short-form mini-nutritional assessment ( MNA-SF ) , implement nursing interventions for malnourished patients, in order to reduce their risk of malnutrition and to improve their nutritional status. Methods The MNS-SF was used to evaluate the nutritional level of hospitalized patients, and mini-nutritional assessment ( MNA ) was utilized for malnutrition patients. The nursing interventions were implemented among malnutrition or malnutrition potential patients. Results Comparing before and after nursing interventions, the scores of MNA-SF and MNA had high uniformity (r=0. 773,0. 805;P<0. 01). After interventions, the scores of MNA-SF and MNA were (12.48 ±0.65) and (25.34 ±1.29) higher than the scores when admitted (t=12.377,15.120;P<0.01). After nursing interventions, the leukomonocyte was (1. 44 ± 0. 66) × 109/L, red cell (3. 90 ± 0. 52) × 1012/L, hemoglobin (120. 26 ± 15. 93) g/L, hematocrit (0. 360 ± 0. 055), albumin (36. 27 ± 3. 78) g/L, globin (29. 92 ± 7. 44)g/L, which were all higher than those before interventions (t=2. 529, 4. 937, 5. 726, 3. 947, 5. 547, 2. 125;P<0. 05);the patients′blood lipid level was (3. 93 ± 0. 90) mmol/L, TG (1. 02 ± 0. 53) mmol/L, LDL-C (1. 09 ± 0. 29) mmol/L and HDL-C (2. 08 ± 0. 58) mmol/L better than those before interventions (t=2. 875, 3. 633, 3. 557, 5. 727;P<0. 01). Conclusions The utilization of MNA-SF and MNA can simple, effective screen out malnutrition risk patients, and then the nursing interventions can reduce the risk of malnutrition in elderly patients with cardiovascular and improve the nutritional status of the patients.
