Objective:To understand the willingness of breast cancer patients to participate in lymphatic reflux training and management after surgery, and analyze its influencing factors.Methods:A total of 157 postoperative patients with breast cancer were selected by convenience sampling method. The investigation tools included general information questionnaire and lymphedema health belief questionnaire.Results:64.3% (101/157) of the patients were willing to participate in lymphatic reflux training and management. Logistic regression analysis showed that ethnic group ( OR=0.06, 95% CI 0.01-0.68), divorce ( OR=0.08, 95% CI 0.01-0.89), benefit cognition ( OR=12.41, 95% CI 4.26-36.19), obstacle cognition ( OR=3.83, 95% CI 1.48-9.91), behavioral clues ( OR=3.72, 95% CI 1.51-9.20) were significant influencing factors of parents' willness of participating in lymphatic reflux training and management( P<0.05). Conclusion:The willingness of patients to participate in lymphatic reflux training and management is at a medium level, which was influenced by ethnic group, marital status, health belief of benefits cognition, obstacle cognition and behavioral clues. Attention should be paid to the implementation during health education for the prevention of lymphedema, and patient′s willness of participating in lymphatic reflux training and management should be improved.

Objective To investigate the clinical characteristics of diabetes complicated with peripheral neu- ropathy and increase the cognition of diabetic peripheral neuropathy in clinical work.Methods The clinical data of 160 diabetic patients were analyzed with retrospective analysis.Results 118 diabetic patients had different levels neuroelectrophysiologic abnormality,and the incidence rate was 73.8 %.The cure rate of diabetic peripheral neuropa- thy was 11.0%.Conclusion The incidence of peripheral neuropathy is high in diabetic patients,neuroelec- trophysiologic examination is a sensitive index in diagnosis of diabetic peripheral neuropathy,and the therapeutic ef- fect of diabetic peripheral neuropathy is poor.

Objective:To investigate the relationship between epicardial adipose tissue (EAT) thickness and left ventricular geometry in patients with obstructive sleep apnea syndrome (OSAS).Methods:Two hundred and twenty-one OSAS patients were enrolled consecutively from the First Hospital of Shanxi Medical University from January to December 2019. According to left ventricular mass index (LVMI) and relative wall thickness (RWT), OSAS patients were divided into 4 groups based on the left ventricular geometry: 110 with normal geometry (NG group), 56 with concentric remodeling (CR group), 32 with concentric hypertrophy (CH group), and 23 with eccentric hypertrophy (EH group). The patients were examineel by echocardiography, the left ventricular end diastolic diameter, LVMI, interventricular septal thickness, left ventricular posterior wall thickness, left ventricle ejcetion fraction, E/A were collected. Age, systolic blood pressure (SBP), diastolic blood pressure (DBP), apnea hypopnea index (AHI), nocturnal lowest oxygen saturation (Lowest-SaO 2), nocturnal mean oxygen saturation (Mean-SaO 2), the percentage of the time that oxygen desaturation below 90%(T90), oxygen desaturation index(ODI), triglyceride (TG), total cholesterol (TC), EAT thickness and the echocardiography parameters were compared among the four groups. The relationships between EAT thickness and the above-mentioned parameters and left ventricular geometry were analyzed by univariate and multivariate linear regressions. Results:①The higher EAT thickness was found in the CH group [(0.50±0.09)cm] and EH group [(0.46±0.07)cm] compared with the NG group [(0.33±0.11)cm] and CR group [(0.36±0.15)cm] (all P<0.05). In addition, age, SBP, DBP, AHI, ODI, T90, LVMI, RWT and E/A ratio were all significantly different among the groups (all P<0.05). ②Univariate linear regression analysis showed that EAT thickness was positively correlated with age, SBP, DBP, AHI, TG, TC and LVMI, RWT, left ventricular geometry, and negatively correlated with Mean-SaO 2 and Lowest-SaO 2. ③Multivariate linear regression analysis showed that EAT thickness was independently correlated with AHI, TG, TC and left ventricular geometry. Conclusions:EAT is independently related to abnormal left ventricular geometry, suggesting that EAT may be involved in the process of left ventricular remodeling.

Objective: LMJ07 is a novel cannabinoid receptorl (CB1R) selective antagonist discovered by our lab. In the present study, its affinity and antagonistic activity against CB1R were evaluated at the molecular and cellular levels by receptor binding experiment, CB1R internalization experiment and by monitoring the change in cytoskeletal and intracellular signal induced by CB1R activation. Methods: With the CB1R selective antagonist rimonabant (SR141716A) as control, the affinity and selectivity of LMJ07 to CB1R and CB2R were assayed by radioligand binding assays, and the G protein-independent antagonistic activity against cannabinoid receptor (CBR) was assayed by enhanced green fluorescein protein (EGFP)-CBR internalization with hierarchiae cluscer anclysis (HCA) analysis. At the same time, we evaluated the changes in cytoskeletal and the intracellular cAMP levels in response to LMJ07 treatment in CHO-CB1 cells by Cellkey label-free assays and homogeneous time-resolved fluorescence (HTRF). Additionally, we also confirmed the CB1R antagonistic efficacy of LMJ07 by detecting the content of Ca2+ in primary cultured hippocampal neuronal cells which could express CB1R with continuous fluorescence detection technology. Results: LMJ07 is a selective CB1R antagonist with high affinity, which can selectively antagonize receptor endocytosis induced by CB1RactivationIt’s affinity and antagonistic efficacy to CB1R were equal to those of rimonabant. In CHO-CB1 cells, LMJ07 (0.01-10μmol/L)could dose-dependently inverse the change in cytoskeletal as well as the increase in intracellular cAMP induced by CBR agonist Win55212-2. In the primary cultured hippocampal neuronal cells, LMJ07 (10 nmol/L-1 μmol/L) could block the increase in [Ca2+] induced by CB1R agonist Win55212-2. Conclusion: LMJ07 is a new selective CB1R antagonist, which shows equal affinity and antagonistic activity against CB1R as the widely accepted CB1R antagonist rimonabant. In addition, the combination of high content analysis (HCS) and Cellkey label-free assay provides a better research tool for rapid and high throughput screening of novel CB1R antagonists.

Follicle-stimulating hormone (FSH) is synthesized and secreted by the anterior pituitary, which binds to its receptors expressed on the membrane of Sertoli cells in the testis to bring about spermatogenesis. With the development of DNA sequencing technology, FSH SNPs rs10835638 and FSHR SNPs rs6165, rs6166, and rs1394205 were detected, which might directly affect the expression of FSH and activity of FSHR, resulting in male spermatogenic dysfunction. This review focuses on the relationship of FSH and FSHR gene polymorphisms with male infertility.

Objective To investigate the proliferative characteristics of fibroblast-like synovial cells (FLS)in osteoarthritis in vitro and the mechanism of the immunosuppressive effect of total glucusides of paeony(TGP).Methods FLS of OA and non-inflamed synovium(NS)were cultured and identified in vitro in the presence or absence of TGP.After incubation,the survival fraction(SF)of FLS was evaluated by MTI' and the TNF-?,IFN-?and bFGF level in cultured FLS supernatant was measured by ELISA.The expression of FLS c-los mRNA and cell cycle of OA-FLS was observed by RT-PCR and flow eytometry respectively at the same time.Results No statistical significant differences were noted between the OA and NS FLS in pro- liferating double time.High doses of TGP suppressed FLS-SF more evidently in OA patients than in NS(P0.05).Conclusion High dose TGP can inhibit OA-FLS proliferation,modulate cy- tokine secretion and c-fos expression in OA.This suggests that TGP has immunosuppressive effect on OA syn- ovitis,probably by preventing the synovial hypertrophy in OA.

Objective To investigate radiological characteristics of the posterior tibial plateau fracture and operative treatments for the fracture.Methods Thirty-one cases of posterior tibial plateau fracture treated between February 2009 and February 2014 were enrolled.There were 19 men and 12 women aged 24-72 years (mean,42.5 years).Injury arose from traffic accidents (13 cases),falls from a height (9 cases),fall on the ground (5 cases),and crash (4 cases).Type Ⅴ in 15 cases and type Ⅵ in 15 cases were classified by the Schatzker classification.Meanwhile,all fractures were identified as three-column pattern.According to the X-ray and CT manifestations of fracture displacement,the cases with minor displacement were grouped as Group A (22 cases) and the cases with major displacement group as Group B (9 cases).Depending on the radiographic characteristics of fracture size and angle off fracture line,anterior approach for reduction and fixation was performed in Group A and combined anterolateral and posteromedial approaches in Group B.Radiographic and functional outcomes were evaluated using the Rasmussen score.Results All cases underwent one-stage surgery uneventfully.Operation time was 80-120 minutes (mean,98 minutes) in group A and was 110-165 minutes (mean,110 minutes) in Group B.Mean total operation time was 105 minutes.Period of follow-up was 6-48 months (mean,21.5 months).Rasmussen radiographic results showed total excellent to good rate of 84％ with 86％ in Group A and 78％ in Group B respectively.Rasmussen functional results showed total excellent to good rate of 87％ with 91％ in Group A and 78％ in Group B respectively.Conclusions Anterior approach or anterolateral approach combined with posteromedial approach for reduction and internal fixation is developed according the radiographic findings and degree of fracture displacement.Clinical outcome is good and associated intraarticular soft tissue injury can be managed concurrently.

Objective To evaluate the feasibility of Mycobacteria growth indicator tube ( MGIT ) liquid culture combined with rifampin resistance test real-time PCR ( Xpert MTB/RIF test) in the diagnosis of tuberculosis.Methods 652 cases of suspected pulmonary tuberculosis from October 2014 to March 2015 in Quzhou People′s Hospital were enrolled. The morning sputum samples were collected for acid-fast staining, L?wenstein-Jensen ( L-J) culture, BACTEC MGIT culture and Xpert MTB/RIF test.Samples with positive results of MGIT liquid culture were subjected to strain identification and drug sensitivity test with fluid method.Methodological comparison between four methods was made and the performance of MGIT liquid culture combined with Xpert MTB/RIF test in the rapid diagnosis and drug resistance detection in Mycobacterium tuberculosis was evaluated by chi-square test. Results Among the samples from 399 confirmed tuberculosis patients, the diagnostic sensitivity of the 4 methods ( acid-fast staining, L-J culture, MGIT culture and Xpert MTB/RIF test) were 17.0%(68/399), 23.8%(95/399), 37.8% (151/399) and 37.3%(149/399) respectively.The sensitivity and specificity of MGIT culture combined with Xpert MTB/RIF test was 39.8%(159/399) and 94.8%(240/253).The sensitivity of MGIT culture combined with Xpert MTB/RIF test was significantly higher than acid-fast staining (χ2 =50.9, P<0.01 ) and L-J culture (χ2 =23.7,P<0.01).The average detection time of MGIT culture was 7.5 days ( smear positive and Xpert MTB/RIF positive), 13.4 days (smear negative and Xpert MTB/RIF positive) and 16.9 days ( smear negative and Xpert MTB/RIF negative) .The sensitivity and specificity of Xpert MTB/RIF test in rifampin resistance detection were 9/9 and 97.3% ( 129/132 ) respectively.The average detection time of fluid method for drug sensitivity test was 8.3 days.Conclusions MGIT liquid culture combined with Xpert MTB/RIF test can detect Mycobacterium tuberculosis and the drug sensitivity rapidly.The method is highly sensitive and specific.It is important for clinical diagnosis and treatment of tuberculosis.
