Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Colorectal cancer(CRC) is one of the most common malignant tumors worldwide, primarily originating from recurrent inflammatory bowel disease(IBD). Therefore, blocking the inflammation-cancer transformation in the colon has become a focus in the early prevention and treatment of CRC. The inflammation-cancer transformation in the colon involves multiple types of cells and complex pathological processes, including inflammatory responses and tumorigenesis. In this complex pathological process, immune cells(including non-specific and specific immune cells) and non-immune cells(such as tumor cells and fibroblasts) interact with each other, collectively promoting the progression of the disease. In traditional Chinese medicine(TCM), inflammation-cancer transformation in the colon belongs to the categories of dysentery and diarrhea, with the main pathogenesis being cold and heat in complexity. This paper first elaborates on the complex molecular mechanisms involved in the inflammation-cancer transformation process in the colon from the perspectives of inflammation, cancer, and their mutual influences. Subsequently, by comparing the pathogenic characteristics and clinical manifestations between inflammation-cancer transformation and the TCM pathogenesis of cold and heat in complexity, this paper explores the intrinsic connections between the two. Furthermore, based on the correlation between inflammation-cancer transformation in the colon and the TCM pathogenesis, this paper delves into the importance of the interaction between inflammation and cancer. Finally, it summarizes and discusses the clinical and basic research progress in the TCM intervention in the inflammation-cancer transformation process, providing a theoretical basis and treatment strategy for the treatment of CRC with integrated traditional Chinese and Western medicine.

Objective To investigate the effect of dorsal repulsive axon guidance protein(Draxin)on the migration of trunk neural crest cells during the early development of embryonic mouse spinal cord.Methods Immunohistochemistry and in situ hybridization were used to detect the expression characteristics of Draxin in early embryonic spinal cord(8 mice each group);In situ hybridization was used to detect the change of migration characteristics of trunk neural crest cells in early embryonic spinal cord of different types of mouse(5 mice each group);in vitro culture method was used to check the effect of Draxin on the migration characteristics of embryonic mouse trunk neural crest cells(16 mice each group).Resultsβ-galactosidase gene Z(LacZ)gene was introduced when Draxin gene was knocked out to produce Draxin gene knockout mice.β-galactosidase staining was used to detect LacZ gene expression in Draxin knockout embryonic mice,and the result showed that Draxin expression was observed in the spinal cord of early embryonic mice since 9.5 days(E9.5).Draxin expression was obvious in the embryonic mice spinal cord in E10.5 period.In situ hybridization was used to detect the expression of Draxin gene in the spinal cord of wild type embryonic mice,and the result further verified the obvious expression of Draxin in the early embryonic mice spinal cord in El0.5 period.Sox10 in situ hybridization was used to detect neural crest cell migration in the spinal cord of embryonic mice in E10.5 period.The result showed that segmental migration of neural crest cells in the early embryonic spinal cord of some Draxin knockout mice was delayed compared with the wild type mice.The effect of Draxin on the migration of wild type early embryonic mice trunk neural crest cells in vitro was tested.The result showed that Draxin reduced the migration distance of neural crest cells in vitro.Conclusion In the early developmental stage of embryonic spinal cord(E9.5-E10.5),neural crest cells migrated exuberant.At the same time,Draxin plays an important inhibitory function in the formation of the specific migration pathways of trunk neural crest cells by promoting neural crest cells migrating away from Draxin expressing regions.

Non-alcoholic fatty liver disease(NAFLD) is a chronic metabolic condition with rapidly increasing incidence, becoming a public health issue of worldwide concern. Studies have shown that farnesoid X receptor(FXR)-based modulation of downstream targets can improve liver function and metabolic status in the patients with NAFLD and may be a potential drug target for treating this di-sease. Great progress has been achieved in the development of drugs targeting FXR for the treatment of NAFLD. A number of studies have explored the traditional Chinese medicine and their active ingredients for the treatment of NAFLD via FXR considering the high safety and efficacy and mild side effects. This paper systematically describes the mechanism of traditional Chinese medicines in the treatment of NAFLD via FXR and the downstream targets, aiming to provide precise targets for the drug development and clinical treatment of NAFLD.

Objective: To investigate the predictive value of SYNTAX-Ⅱ score on long term prognosis of patients diagnosed with chronic total occlusion (CTO) and received percutaneous coronary intervention (PCI). Methods: Patients undergoing CTO-PCI in Fuwai hospital from January 2010 to December 2013 were enrolled in this retrospective analysis. The SYNTAX-Ⅱ score of the patients was calculated. According to SYNTAX-Ⅱ score tertiles, patients were stratified as follows: SYNTAX-Ⅱ≤20, 2027. Primary endpoint was major adverse cardiac events (MACCE), including all-cause death, myocardial infarction, stroke and any revascularization. Secondary endpoints included stent thrombosis, heart failure and target lesion failure (TLF). Patients were followed up by outpatient visit or telephone call at 1 month, 6 months and 1 year after PCI, and annually up to 5 years. Multivariate Cox regression model was used to analyze the independent risk factors of all-cause death in patients undergoing CTO-PCI. The predictive value of SYNTAX score with SYNTAX-Ⅱ score for all-cause death was evaluated by the receiver operating characteristic (ROC) curve and the area under the curve (AUC). Results: A total of 2 391 patients with CTO and received PCI were enrolled in this study. The mean age was (57.0±10.5) years, 1 994 (83.40%) patients were male. There were 802 patients in lower tertile group (SYNTAX-Ⅱ≤20), 798 patients in intermediate group (2027). At the end of 5-year follow-up, the loss to follow-up rate of the three groups was 9.10%(73/802), 10.78%(86/798)and 8.85%(70/791), respectively. The rate of all-cause mortality (1.78% (13/729) vs. 3.65% (26/712) vs. 9.02% (65/721), P<0.001), cardiac death (1.37% (10/729) vs. 2.11% (15/712) vs. 4.85% (35/721), P<0.001), target vessel myocardial infarctions (4.25% (31/729) vs. 4.49% (32/712) vs. 7.07% (51/721), P=0.03), probable stent thrombosis (1.51% (11/729) vs. 2.81% (20/712) vs. 3.61% (26/721), P=0.04) and heart failure (1.78% (13/729) vs. 1.97% (14/712) vs. 5.41% (39/721), P<0.001) increased in proportion to increasing SYNTAX-Ⅱ score (all P<0.05). Multivariable Cox regression analysis indicated that female (HR=2.05, 95%CI 1.12-3.73, P=0.01), left ventricular ejection fraction (HR=0.97, 95%CI 0.95-1.00, P=0.05) and SYNTAX-Ⅱ score (HR=1.07, 95%CI 1.02-1.11,P=0.01) were independent predictors for all-cause mortality in patients undergoing CTO-PCI. The predicted value of the SYNTAX-Ⅱ score for all-cause death was significantly higher than the SYNTAX score (AUC 0.71 vs. 0.60, P=0.003). Conclusion: For CTO patients who underwent percutaneous coronary intervention, SYNTAX-Ⅱ score is an independent predictor for 5-year all-cause death, and SYNTAX-Ⅱ serves as an important predictor for all-cause death in these patients.

Pneumoconiosis, an interstitial lung disease that occurs from breathing in certain kinds of damaging dust particles, is a major occupational disease in China. Patients diagnosed with occupational pneumoconiosis can avail of free medical treatment, whereas patients without a diagnosis of occupational diseases cannot not claim free medical treatment in most provinces from the government before 2019. This study aimed to analyze the priority of medical facility selection and its influencing factors among patients with pneumoconiosis. A total of 1,037 patients with pneumoconiosis from nine provinces in China were investigated. The health service institutions most frequently selected by the patients were county-level hospitals (37.5%). The main reason for the choice was these hospitals' close distance to the patients' homes (47.3%). The factors for the choice of health care institutions were living in the eastern region (

Objective:To explore the effects of Shenwei Ningyu pills （SNP）， a new Chinese medicine for depression， on the immunoinflammatory response mediated by Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88） signaling pathway in the hippocampus of rats exposed to chronic restraint stress （CRS）. Method:Forty-four male Sprague Dawley rats were randomly enrolled into a normal group， a model group， an escitalopram group， and an SNP group. Except for the rats in the normal group， all rats were exposed to CRS and isolated rearing for 21 days continuously. Rats in the escitalopram group and the SNP group were administered with escitalopram （30 mg·kg^-1） and SNP （18 mg·kg^-1） one hour prior to CRS， respectively. The changes in body weight， sucrose preference index， horizontal movement scores， and vertical movement scores were observed by body weight assessment， sucrose preference test， and open field test. The expression of hippocampal TLR4 and MyD88 was detected by Western blot. The content of serum interleukin-1β （IL-1β）， IL-10， and tumor necrosis factor-α （TNF-α） was detected by enzyme-linked immunosorbent assay （ELISA）. Result:The results of the behavioral assessment showed that there was no significant difference in the changes of behavioral baselines among the groups before intervention. However， significant differences were found among the groups following different interventions. The body weight， sugar preference index， horizontal movement score， and vertical movement score of rats in the model group decreased after CRS for 21 days as compared with those in the normal group （P<0.01）. The above indicators in the SNP group and the escitalopram group were higher than those in the model group （P<0.01）， which indicated that SNP exerted an obvious antidepressant effect. The results of Western blot and ELISA showed that compared with the normal group， the model group showed elevated levels of hippocampal TLR4 and MyD88 and serum IL-1β and TNF-α （P˂0.01） and dwindled serum IL-10 （P˂0.01）， while SNP and escitalopram reversed the conditions in the model group （P˂0.01） except for TNF-α. Conclusion:The present study indicated that the antidepressant effect of SNP was presumedly achieved by inhibiting the immunoinflammatory response mediated by the TLR4/Myd88 signaling pathway in CRS rats.

Objective:To explore the difference and clinical significance of paraspinal muscle degeneration between single-segment degenerative lumbar spondylolisthesis and degenerative lumbar spinal stenosis.Methods:From January 2014 to October 2020, a retrospective analysis of 30 patientswere diagnosed with L 4,5 degenerative lumbar spondylolisthesis, aged 61.63±8.42 years old (range 44 to 82 years old), body mass index 24.07±3.17 kg/m 2 and 30 patientswere diagnosed with L 4,5 degenerative lumbar spinal stenosis, aged 59.67±12.89 years old (range 31 to 80 years old), body mass index 25.29±3.48kg/m 2, both of them went on surgery in department of spine surgery, shengjing hospital, China Medical University.30 healthy people were selected from outpatient physical examination in the control group, aged 58.33±7.36 years old (range 52 to 83 years old), body mass index 25.72±2.58 kg/m 2. These three groups were all male. Select all patients with L 3,4, L 4,5 and L 5S 1 disc level axial MRI images, and use the deep learning automatic segmentation measurement system developed by our hospital and Shenyang Institute of Automation Chinese Academy of Sciences to measure multifidus muscle cross sectional area (MMCSA), erector spinae cross sectional area (ESCSA), multifidus muscle fatty infiltration rate (MMFIR) and erector spinae fatty infiltration rate (ESFIR). One-way ANOVA was used to test the imaging parameters of multifidus and erector spinae of the three groups, and LSD- t test was used to compare the imaging parameters in each segment of paraspinal muscles. Results:The gender of three groups were male, there was no significant difference in age ( H=5.303, P>0.05), and there was no significant difference in body mass index ( F=2.267, P>0.05). Multifidus muscle cross-sectional area in L 3,4: degenerative lumbar spondylolisthesis groupincreased 189.11 mm 2 compared with degenerative lumbar spinal stenosis group ( P=0.010). Multifidus muscle cross-sectional area in L 4,5: compared with healthy people group, degenerative lumbar spondylolisthesis group decreased 205.52 mm 2 ( P=0.002), while degenerative lumbar spinal stenosis group decreased 184.14 mm 2 ( P=0.006). Multifidus muscle cross-sectional area in L 5S 1: compared with degenerative lumbar spinal stenosis group, degenerative lumbar spondylolisthesis group decreased 174.93 mm 2 ( P=0.018); compared with healthy people group, degenerative lumbar spondylolisthesis group decreased 406.06 mm 2 ( P<0.001), while degenerative lumbar spinal stenosis group decreased 231.13 mm 2 ( P=0.002). Erector spinae cross sectional area in L 4,5: compared with healthy people group, degenerative lumbar spinal stenosis group decreased 398.70 mm 2 ( P=0.006). Erector spinae cross sectional area in L 5S 1: compared with degenerative lumbar spinal stenosis group, degenerative lumbar spondylolisthesis group decreased 500.02 mm 2 ( P<0.001); compared with healthy people group, degenerative lumbar spinal stenosis group decreased 455.37 mm 2 ( P<0.001). Compared with healthy group, the multifidus muscle fatty infiltration rate of degenerative lumbar spondylolisthesis group in L 3,4 increased 4.96% ( P=0.001). Compared with degenerative lumbar spinal stenosis group, the erector spinae fatty infiltration rate of degenerative lumbar spondylolisthesis group in L 5S 1 decreased 5.41% ( P=0.004). Compared with healthy group, the erector spinae fatty infiltration rate of degenerative lumbarspinal stenosis group in L 5S 1 increased 5.02% ( P=0.008) . Conclusion:Paraspinal muscle cross sectional area of each segment in degenerative lumbar spondylolisthesis group and degenerative lumbar spinal stenosis group decreased in different degrees. In degenerative lumbar spondylolisthesis group, the degree of multifidus muscle fat infiltration was more significant, while indegenerative lumbar spinal stenosis group,the degree of erector spinal fat infiltration was higher.

Objective: To evaluate the safety and long-term clinical efficacy of percutaneous coronary intervention (PCI) in patients with in-stent chronic total occlusion (IS-CTO) lesions. Metheds: This is a retrospective analysis. Patients with IS-CTO who underwent PCI in Fuwai hospital from January 2010 to December 2013 were enrolled. A total of 212 patients who met the inclusion criteria were included in the IS-CTO group, 212 matched patients with primary CTO lesions were included in the de novo CTO group. The incidence of complications and the success rate of PCI were compared between the two groups. Successful PCI was defined as successfully implantation of stent(s) at target CTO lesions. The primary endpoint was defined as a composite event of cardiac death and myocardial infarction (MI). Secondary endpoints including PCI success, all-cause death, cardiac death, MI, target vessel related MI, revascularization, target vessel revascularization, heart failure for rehospitalization. The patients were followed up for 5 years after PCI. Results: A total of 424 cases were included. The mean age was (57.8±10.5) years, there were 364 males in this cohort. The left ventricular ejection fraction was significantly lower ((58.7±9.2)% vs. (61.0±7.7)%, P=0.01) and the SYNTAX scores was significantly higher (19.4±8.3 vs. 15.3±10.0, P<0.01) in IS-CTO group than that in de novo CTO group. The proportion of patients with target CTO lesions in left anterior descending artery was significantly higher (42.9% (50/212) vs. 23.6% (91/212), P<0.01) in IS-CTO group than that in de novo CTO group. The rate of successful PCI (71.7% (152/212) vs. 69.8% (148/212), P=0.70) and complication (40.6% (86/212) vs. 36.3% (77/212), P=0.37) was similar between the two groups. The incidence of primary endpoint at 5 years was significantly higher in IS-CTO group (10.8% (23/212) vs. 4.7% (10/212), P=0.02), which was driven by higher incidence of MI (9.0% (19/212) vs. 4.2% (9/212), P=0.05). There were a trend of higher secondary endpoints in IS-CTO group (all P>0.05). Conclusion: The safety and effectiveness of PCI are acceptable in patients with IS-CTO, but the risk of long-term cardiac death and MI is higher among patients with IS-CTO as compared to patients with primary CTO lesions.

Although DNA 5-hydroxymethylcytosine (5hmC) is recognized as an important epige-netic mark in cancer, its precise role in lymph node metastasis remains elusive. In this study, we investigated how 5hmC associates with lymph node metastasis in breast cancer. Accompanying with high expression of TET1 and TET2 proteins, large numbers of genes in the metastasis-positive pri-mary tumors exhibit higher 5hmC levels than those in the metastasis-negative primary tumors. In contrast, the TET protein expression and DNA 5hmC decrease significantly within the metastatic lesions in the lymph nodes compared to those in their matched primary tumors. Through genome-wide analysis of 8 sets of primary tumors, we identified 100 high-confidence metastasis-associated 5hmC signatures, and it is found that increased levels of DNA 5hmC and gene expression of MAP7D1 associate with high risk of lymph node metastasis. Furthermore, we demonstrate that MAP7D1, regulated by TET1, promotes tumor growth and metastasis. In conclusion, the dynamic 5hmC profiles during lymph node metastasis suggest a link between DNA 5hmC and lymph node metastasis. Meanwhile, the role of MAP7D1 in breast cancer progression suggests that the metastasis-associated 5hmC signatures are potential biomarkers to predict the risk for lymph node metastasis, which may serve as diagnostic and therapeutic targets for metastatic breast cancer.
