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 spatial distribution of Aedes albopictus in China at different time periods from 2000 to 2019, so as to provide insights into precise management of Ae. albopictus in China. Methods Data pertaining to the distribution of Ae. albopictus in China from 2000 to 2019 were collected through literature retrieval with terms of “Aedes albopictus”, “monitoring”, “survey”, “density”, “distribution”, and “outbreak” in national and international databases. The title and time of the publication, sampling sites, sampling time, mosquito capture methods, and mosquito species and density were extracted, and the longitude and latitude of sampling sites were obtained through Baidu Map. Meteorological element data at meteorological observation stations within China were obtained from the National Climatic Data Center of the United States, and the annual maximum temperature, annual minimum temperature, average temperature in January, average temperature in July, annual temperature range, daily temperature range and relative humidity were calculated and subjected to Kriging interpolation. Monthly cumulative precipitation grid data and monthly average temperature grid data with a resolution of 1 km for China from 2000 to 2019 were obtained from the National Tibetan Plateau Scientific Data Center, and the annual precipitation and annual average temperature were calculated cumulatively. Population density data in China from 2000 to 2019 were obtained from the WorldPop Hub, and the gross domestic product (GDP) in China was obtained from the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences. The above data were divided into 5-year intervals to calculate data during the periods from 2000 to 2004, from 2005 to 2009, from 2010 to 2014, and from 2015 to 2019. Ae. albopictus distribution data were modeled in China from 2000 to 2019 and during each period with the classification random forest (RF) model, to predict the distribution of Ae. albopictus across the country and analyze the distribution of Ae. albopictus based on the seven major climate zones in China. The performance of RF models was evaluated by accuracy, precision, recall, and area under the receiver operating characteristic curve (AUC), and the importance of each feature in the RF model was evaluated with mean decrease accuracy (MDA). Results A total of 1 191 Chinese publictions and 391 English publications were retrieved, among which 580 articles provided detailed data on the sampling sites of Ae. albopictus and specific sampling years, meeting the inclusion criteria. A total of 2 234 Ae. albopictus sampling sites were included in China from 2000 to 2019, and RF modeling results showed that the overall Ae. Albopictus distribution area was mainly found in southeastern and southwestern provinces of China from 2000 to 2019, with scattered distribution in coastal areas of northeastern provinces, such as Liaoning Province. The accuracy, precision, recall and AUC of the RF model were 0.915 to 0.947, 0.933 to 0.975, 0.898 to 0.978, and 0.902 to 0.932 for the distribution of Ae. albopictus at different time periods from 2000 to 2019. Among all features in the RF models, population density was the most contributing factor to the distribution of Ae. albopictus in China, followed by GDP, and all meteorological variables contributed relatively less to the predictive power of the RF model. In China’s seven major climate zones, Ae. albopictus was almost entirely distributed in the marginal tropical humid region, the north subtropical humid region, and the warm temperate semi-humid region. The combined distribution area of these three zones accounted for 100.0% of the national distribution area from 2000 to 2004, from 2005 to 2009, and from 2010 to 2014, and 99.9% from 2015 to 2019, and the proportion of Ae. albopictus distribution area in the warm temperate semihumid region increased gradually from 20.2% to 30.2%. Conclusions Ae. albopictus is mainly distributed in the southeastern and southwestern provinces of China and is greatly influenced by population and economic factors. The warm temperate semi-humid region in China is gradually becoming a hot spot for the distribution of Ae. albopictus.

Objective To understand the individual radiation dose levels and changes of occupational external exposure among radiation workers in a steel group from 2020 to 2023, and to provide a basis for strengthening radiation protection in the group. Methods According to the Specifications for individual monitoring of occupational external exposure (GBZ 128-2019), individual monitoring was conducted using a thermoluminescent dosimeter, with each monitoring cycle lasting 90 days, totaling four cycles per year. Individual monitoring data of occupational external exposure among radiation workers in the steel group from 2020 to 2023 were collected for statistical analysis. Results A total of 5889 monitoring records were collected from radiation workers across 37 affiliated units of the steel group during the period of 2020-2023. The average annual effective dose was 0.150 mSv, the maximum annual effective dose was 3.84 mSv, and 0.3% monitored workers showed annual effective doses exceeding 1 mSv. The average annual effective dose in 2023 was 0.146 mSv, which was lower than in 2020 but higher than in 2021 and 2022 (Z = −6.657 to 14.129, P < 0.001). The number of monitored workers in industrial and medical sectors accounted for 86.9% and 13.1%, respectively. Their average annual effective doses were 0.152 mSv and 0.140 mSv, respectively, and the difference was statistically significant (Z = −7.969, P < 0.001). In the industrial sector, the average annual effective dose for the monitored workers in industrial radiography was significantly higher than other occupations (Z = −8.094, P < 0.001). There was a significant difference in average annual effective dose among workers of different occupational categories in the medical sector (H = 67.040, P < 0.001). The average annual effective doses were relatively high for diagnostic radiology and nuclear medicine. Additionally, the average annual effective doses for male and female radiation workers were 0.150 mSv and 0.152 mSv, respectively (P > 0.05). Conclusion The average annual effective dose of radiation workers in the steel group was at low levels for four consecutive years, which meet the requirements of the national standard. However, to maintain the individual radiation dose levels of radiation workers as low as reasonably achievable, it remains necessary to strengthen radiation protection management in the steel group.

Objective:To corelate thromboelastography (TEG)-related parameters and D-dimer and fibrinogen levels with the severity of preeclampsia and pregnancy outcomes in patients with preeclampsia.Methods:A case-control study was conducted involving 92 patients with preeclampsia who received treatment at Northwest Women's and Children's Hospital between March 2022 and September 2023 (patient group) and 92 healthy pregnant women who underwent routine check-ups during the same period (control group). All participants underwent TEG tests, and D-dimer and fibrinogen levels were measured. Intergroup comparisons were performed, and patients were categorized based on the severity of their condition. TEG parameters and D-dimer and fibrinogen levels were compared among patients with varying severities of preeclampsia. TEG-related parameters were correlated with D-dimer and fibrinogen levels. Adverse pregnancy outcomes in the patient group were statistically analyzed, and risk factors for these adverse outcomes in women with preeclampsia were identified.Results:In the patient group, the R and K values were (3.06 ± 0.36) minutes and (1.21 ± 0.14) minutes, respectively, both of which were significantly lower than those in the control group [(5.44 ± 0.61) minutes, (1.79 ± 0.21) minutes, t = 32.22, 22.04, both P < 0.001]. The α angle, CI value, MA value, and D-dimer and fibrinogen levels in the patient group were (71.31 ± 7.63)°, (3.89 ± 0.41), (65.71 ± 7.01) mm, (2.22 ± 0.24) mg/L, and (4.51 ± 0.49) g/L, respectively, all of which were significantly higher than those in the control group [(64.85 ± 6.79)°, (2.19 ± 0.23), (58.96 ± 6.09) mm, (1.92 ± 0.21) mg/L, (3.75 ± 0.40) g/L, t = -6.06, -34.68, -6.97, -9.02, -11.52, all P < 0.001]. In the patient group, severe cases had significantly lower R and K values compared with mild cases, while the α angle, CI value, MA value, and D-dimer and fibrinogen levels were significantly higher in severe cases than in mild cases ( t = 11.06, 7.16, -8.01, -12.05, -3.91, -13.74, -8.269, all P < 0.001). In patients with preeclampsia, the R and K values were negatively correlated with D-dimer levels, and the R value was negatively correlated with fibrinogen level ( r = -0.504, -0.612, -0.493, all P < 0.05). In addition, the MA and CI values were positively correlated with D-dimer level, and the α angle was positively correlated with fibrinogen level ( r = 0.436, 0.534, 0.492, all P < 0.05). Among the participants, 41 women experienced adverse pregnancy outcomes. In patients with adverse pregnancy outcomes, the R and K values were (2.48 ± 0.25) minutes and (1.12 ± 0.14) minutes, which were significantly lower than those in patients without adverse pregnancy outcomes [(2.75 ± 0.29) minutes, (1.28 ± 0.13) minutes, t = 4.71, 5.67; both P < 0.001]. The α angle, CI value, MA value, and D-dimer and fibrinogen levels in patients with adverse pregnancy outcomes were (76.62 ± 8.01)°, (4.42 ± 0.46), (69.77 ± 7.06) mm, (2.57 ± 0.27) mg/L, and (4.97 ± 0.51) g/L, all of which were significantly higher than those in patients without adverse pregnancy outcomes [(67.04 ± 7.01)°, (3.46 ± 0.37), (62.45 ± 6.82) mm, (1.94 ± 0.21) mg/L, (4.14 ± 0.43) g/L, t = -6.11, -5.03, -11.09, -12.25, -8.46, all P < 0.001]. Logistic regression analysis indicated that R and K values were protective factors for adverse pregnancy outcomes ( OR < 1, P < 0.05), while MA value, α angle, CI value, and D-dimer and fibrinogen levels were independent risk factors ( OR > 1, P < 0.05). Conclusion:TEG-related parameters differ significantly between patients with preeclampsia and healthy pregnant women. These parameters are correlated with the severity of preeclampsia, as well as with D-dimer and fibrinogen levels. TEG-related parameters are risk factors for adverse pregnancy outcomes in patients with preeclampsia.

In recent years,the use of bioprosthetic mitral valves has been increasing,leading to a growing number of patients experiencing bioprosthesis degeneration,significantly impacting their quality of life.The high risk of reoperation has deprived many patients with mitral bioprosthesis degeneration of the opportunity for a second surgery.With the rapid development of interventional procedures in our country,transcatheter mitral valve-in-valve replacement is gradually being accepted by a large number of patients with bioprosthesis degeneration.We report a case of transcatheter mitral valve-in-valve replacement via transseptal puncture.The surgical plan was carefully formulated based on preoperative CT evaluation,and the patient underwent the procedure smoothly with no significant adverse events postoperatively.Transcatheter mitral valve-in-valve replacement may be a better alternative for patients at high risk of mitral bioprosthesis degeneration.

Objective To evaluate the effect of manual massage on complications after endoscopic foam sclerotherapy injection for the treatment of internal hemorrhoids.Methods Consecutive 113 patients with grade Ⅰinternal hemorrhoids were prospectively enrolled and completed endoscopic foam sclerotherapy.The patients were randomly divided into a massage group(n=65)and a control group(n=68).Massage group performed manual perianal massage,Visual analogue scale(VAS)was used to evaluate perianal pain.The postoperative bleeding,short-term and long-term efficacy were also compared.Results The median VAS of 24 h postoperation was 1.0(0.0,3.0)in massage group,which was significantly lower than 2.0(1.0,4.0)in control group,the difference was statistically significant(P=0.014).The no bleeding rate of one week postoperation was 84.6％in massage group,which was significantly higher than 64.7％in control group,the difference was statistically significant(P=0.009).After 12 weeks,6 months and 12 months of follow-up,there were no significant differences in cure rate and remission rate between the two groups(P＞0.05).Conclusion Manual massage after endoscopic sclerosing agent injection is beneficial to relieve postoperative pain of grade Ⅰ internal hemorrhoids and reduce bleeding.

AIM:This study aimed to investigate the mechanism by which celoside I enhances mitophagy in a model of optic nerve injury through regulation of reactive oxygen species(ROS)-mediated c-Jun N-terminal kinase(JNK)/c-Jun signaling pathway.METHODS:Twenty-four New Zealand white rabbits were randomly divided into four groups:sham surgery,model,mecobalamin,and experimental group.Optic nerve injury was induced in the model,mecobala-min,and experimental groups,while the sham surgery group underwent a sham procedure.The mecobalamin group re-ceived mecobalamin,the experimental group received celoside I,and the sham surgery and model groups received saline.Interventions were administered daily for 28 d.Various techniques including endoscopy,hematoxylin-eosin(HE)stain-ing,TUNEL method,immunofluorescence staining and Western blot were used to assess fundus condition,retinal mor-phology,apoptosis,ROS expression,and protein levels in the retina.RESULTS:Fundus examination revealed im-proved blood flow in the mecobalamin and experimental groups compared to the model group.Retinal morphology showed enhanced retinal ganglion cells(RGCs)in the mecobalamin and experimental groups.Apoptosis index was lower in the mecobalamin group compared to the experimental group.Immunofluorescence staining indicated reduced ROS and P62 ex-pression and increased parkin and microtubule-associated protein light chain 3(LC3)expression in the experimental group compared to the mecobalamin group.Protein analysis showed decreased JNK,c-Jun,and P62 levels,and increased parkin and LC3 levels in the mecobalamin and experimental groups compared to the model group.CONCLUSION:Celo-side I reduces ROS expression,inhibits the JNK/c-Jun pathway,enhances mitophagy,reduces apoptosis,and protects RGCs in optic nerve injury models.

Objective To analyze the sensitivity of ARHGAP8 in predicting the efficacy of neoadjuvant chemotherapy in the patients with locally advanced mid-low colorectal cancer and provide accurate evidence for the treatment of advanced colorectal cancer.Methods The differentially expressed gene ARHGAP8 was screened out by bioinformatics analysis.Cancer tissue and rectal tissue of 68 patients with primary rectal cancer were select-ed.The rectal cancer tissue samples and the rectal tissue samples were collected for clinical validation of ARH-GAP8 expression by quantitative real-time PCR,Western blotting,and immunohistochemistry.The clinical and pathological features such as gender,age,tumor stage,differentiation degree,and pathological type of the pa-tients were collected for functional validation.Forty-four patients with locally advanced mid-low rectal cancer who received neoadjuvant chemotherapy were selected for immunohistochemical examination of ARHGAP8 expres-sion.The expression level of ARHGAP8 was compared between before and after chemotherapy and among different efficacy groups.Results The bioinformatics analysis revealed differences in the expression level of ARHGAP8 between the cancer tissue and rectal tissue(P＜0.001).The expression level of ARHGAP8 was correlated with tumor stage(P=0.024),lymph node metastasis(P=0.007),and age(P=0.005).Quantitative real-time PCR results showed that the mRNA level of ARHGAP8 in the cancer tissue was higher than that in the rectal tis-sue(P＜0.001).Western blotting and immunohistochemistry results demonstrated that the protein level of ARH-GAP8 in the cancer tissue was higher than that in the rectal tissue(P=0.011).The expression of ARHGAP8 was correlated with tumor size(P=0.010)and pathological stage(P=0.005),while it showed no significant association with tumor differentiation degree,lymph node metastasis,liver metastasis,Ki-67,or microsatellite instability expression level.The 44 patients receiving neoadjuvant chemotherapy included 13,8,8,and 15 pa-tients of tumor regression grades 0,1,2,and 3,respectively.Among them,65.91％(29/44)patients showed responses to the treatment.After neoadjuvant chemotherapy,the expression of ARHGAP8 in the cancer tissue was down-regulated in the patients who responded to the chemotherapy(P＜0.001).The response rate in the patients with low protein level of ARHGAP8 was 92.86％,which was higher than that(53.33％)in the patients with high pro-tein level of ARHGAP8(P=0.033).Conclusions ARHGAP8 is highly expressed in the rectal cancer tissue.The pa-tients with locally advanced mid-low rectal cancer and low ARHGAP8 expression are more sensitive to neoadjuvant chemotherapy with the XELOX protocol.ARHGAP8 can serve as a potential biomarker for the occurrence and develop-ment of rectal cancer and an important index for evaluating the efficacy of neoadjuvant chemotherapy with the XELOX protocol in the patients with locally advanced mid-low rectal cancer.

Objective To observe the value of the scoring model of MRI features for predicting proliferative hepatocellular carcinoma(HCC).Methods Data of 241 patients with pathologically confirmed HCC,including 90 cases of proliferative HCC and 151 cases of non-proliferative HCC were analyzed retrospectively.Univariate and multivariate logistic regression were used to compare the clinical and MRI findings evaluated according to liver imaging reporting and data system version 2018 between groups.The independent predictive factors of proliferative HCC were screened,and scores were assigned according to the weight,then a scoring model was constructed.Receiver operating characteristic(ROC)curve was drawn,and the area under the curves(AUC)were calculated to assess the predictive efficacy of this model.The patients were divided into high and low proliferation risk subgroups based on the optimal score thresholds.The recurrence free survival(RFS)rates and early RFS rates were compared between groups and subgroups.Results MRI showed tumor corona enhancement,arterial phase annular hyper-enhancement,intratumoral vessels,much focus parenchymal low enhancement and irregular tumor margins were all independent predictive factors for proliferative HCC(OR=3.287,2.362,4.542,2.997,2.379,all P＜0.05),which were then were scored with 7,5,9,7 and 5,respectively,with a total score of 0-33.AUC of the obtained scoring model for predicting proliferative HCC was 0.818.Taken 9 points as the optimal score thresholds,97 cases were assigned into high proliferation subgroup and 144 into low proliferation risk subgroups).Significant differences of RFS rates and early RFS rates were found between groups and subgroups(all P＜0.05).Conclusion MRI features scoring model could effectively predict proliferative HCC.
