Objective To explore the protective effect of rosiglitazone on insulin resistance( IR)induced by high glucose in vascular endothelial cells and its possible mechanism. Methods Human umbilical vein endothelial cells( HUVECs) was divided into 3 groups:the normal control group cultivated in DEME medium with 5. 5 mmol·L-1 glucose;the high glucose group( HG)cultivated in DEME medium with 33 mmol · L-1 glucose for 24 h after the IR model was set up;the rosiglitazone group cultivated in DEME medium with 33 mmol·L-1 glucose and 10 μmol·L-1 of rosiglitazone for 24 h after the IR model was set up. The cell viability,nitric oxide(NO),endothelin-1(ET-1),mitochondrial membrane potential,reactive oxygen species ( ROS),p-IKK and IkBa protein levels were detected. Results Compared with the normal control,the cell viability,the level of NO and the mitochondrial membrane potential were decreased,levels of ET-1 and ROS increased,p-IKK expression was up-regulated,and IκBα expression was down-regulated in HG group(all P〈0. 01). Rosiglitazone reversed these changes in a time-dependent manner(P〈0. 05). Conclusion Rosiglitazone has the protective effect on insulin resistance induced by high glucose in vascular endothelial cells via inhibiting ROS/IKK signaling pathway.

Objective: To account the direct cost of uterine cervix carcinoma treatment in China and to explore the related factors which influence the direct financial burden of the disease. Methods: Data was collected through the medical record system and telephone interviews in 14 county-level hospitals and 9 provincial and municipal hospitals from 14 provinces/municipalities enrolled in the Chinese National Health Industry Research Project in 2015. The direct financial burden of uterine cervix carcinoma treatment consisted of the direct medical cost and the direct non-medical cost of treatment in different pathological cervical cancer stages and precancerous lesions. Multiple liner regression method was used to analyze the factors affecting the costs. Results: The age of the 3 246 patients was (46.40±10.43) years, including 2 423 patients from provincial and municipal hospitals and 823 patients from county-level hospitals. The direct financial burden for one patient of pathological uterine cervix carcinoma stage or precancerous lesion ranged from 10 156.3 yuan to 75 716.4 yuan in provincial and municipal hospitals, and for patients from county-level hospitals, the cost was between 4 927.9 yuan and 47 524.8 yuan per person. There was a wide gap between the direct financial burden of patients in different disease stages. The direct financial burden of patients with precancerous lesions ranged from 4 927.9 yuan per person to 11 243.0 yuan per person, as for patients of pathological uterine cervix carcinoma stages, the direct financial burden was between 29 274.6 yuan and 75 716.4 yuan per person. The factors which influence direct financial burden would include: the levels of the hospital, pathological period, medicare reimbursement, days of treatment, and the methods of treatment (P<0.001). Conclusion The direct financial burden of diseases in patients with pathological uterine cervix carcinoma stage or precancerous lesion differed in different levels of hospital and pathological periods. In addition, medicare reimbursement, days of treatment, and the methods of treatment all had impact on it.

Objective To evaluate the feasible cervical cancer screening strategies in rural China. Methods The study was based on the health industry scientific research project of National Health Commission in 2015, cervical cancer screening technology and demonstration research suitable for rural areas in China, we collected health economics and epidemiological parameters and established the unscreening model and screening model with Treeage Pro 2011 software. Combining with the data acquired from site investigation, including population screening, treatment-related clinical materials and cost data, we simulated the occurrence and the development of cervical cancer of rural women in China under different screening and intervention programs and predicted the screening effects [cumulative incidence, cumulative risk of disease, life years and quality adjusted life years (QALY), gains] and costs after 20 years, and using health economic evaluation analysis (cost-effectiveness analysis, cost-utility analysis, cost-benefit analysis). Screening programs included five screening strategies [visual inspection with acetic acid/lugol's iodine (VIA/VILI), careHPV, ThinPrep cytology test (TCT), careHPV+TCT, careHPV+VIA/VILI] and three screening intervals (1-year, 3-year, 5-year), a total of fifteen screening programs. Results Compared with no screening, fifteen screening programs reduced the cumulative incidence by 22.65%-51.76%. Compared with TCT or VIA/VILI, for the same screening interval, the reduced cumulative incidence, the amounts of life-year saved and QALY and benefits gained of careHPV were the highest. The cost-effectiveness ratios of these screening programs ranged (0.44-3.24)×104 Yuan per life-year saved, cost-utility ratios ranged (0.15-1.01)×104 Yuan per QALY, benefit-cost ratios ranged 7.73-59.10. The results of incremental cost-effectiveness ratios showed that VIA/VILI every five years, VIA/VILI every three years, careHPV every five years, careHPV every three years and careHPV every year were dominant programs. Conclusions VIA/VILI screening is cost-effective, careHPV is slightly more expensive but more effective. In rural China, careHPV screening every five years could be recommended. This study provides a basis for the determination of cervical cancer screening methods feasible for rural areas in China.

To investigate the degradation of polycyclic aromatic hydrocarbons (PAHs) and the changes of rhizosphere microorganisms in the rhizosphere soil of Leymus chinensis during the remediation of PAHs contaminated soil by Comamonas testosteroni (C.t)-assisted Leymus chinensis, we evaluated the removal of PAHs in the rhizosphere of Leymus chinensis using gas chromatography-mass spectrometry (GC-MS), analyzed the bacterial community and the diversity in Leymus chinensis rhizosphere soil by high-throughput sequencing technology, characterized the correlation among PAHs degradation and bacterial community components performing redundancy analysis (RDA) and network analysis, and predicted PAHs degradation potential via PICRUSt software in this paper. The degradation of PAHs in the rhizosphere of Leymus chinensis was promoted, the abundance and diversity of bacteria and the correlation among bacteria and PAHs were changed, and the degradation potential of PAHs in Leymus chinensis rhizosphere soil was enhanced in the later stage of phytoremediation (60-120 d) due to the incorporation of C.t. The accelerated degradation of three PAHs (Nap, Phe, BaP) was accompanied by the differ abundance and correlation of Proteobacteria (Sphingomonas, MND1, Nordella), Actinomycetes (Rubrobacter, Gaiella), Acidobacteria (RB41) and Bacteroides (Flavobacterium) affected by C.t. The results provide new insight into the microorganism choices for microbial assisted plant remediation of soil PAHs and the mechanisms of enhanced PAHs degradation via the combination of Comamonas testosteroni engineering bacteria and plants.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.
