Objective: To explore the changes of mechanosensitive channels Piezos (Piezo 1 and Piezo 2) in neurogenic bladder (NB) of young rats and their effects,so as to provide reference for clinical search of new therapeutic targets. Methods: A total of 30 female young SD rats were divided into 5 groups based on random number table method:sham operation group (sham),2-week nerve transection group (NB-2W),6-week nerve transection group (NB-6W),2-week nerve transection + Piezos inhibitor group (NB-P-2W) and 6-week nerve transection + Piezos inhibitor group (NB-P-6W),with 6 rats in each group.The NB models were constructed by transecting the L6 and S1 spinal nerves of young rats.The NB-2W and NB-6W groups were not intervened after modeling,while the NB-P-2W and NB-P-6W groups were intraperitoneally injected with Piezos inhibitor GsMTx4 (10 mg/kg) every 2 days after modeling.Bladder cystometry and ultrasound were performed after 2 and 6 weeks of transection.The expressions of Piezos and fibrosis-related indexes (Collagen Ⅰ and α-smooth muscle actin) were detected in bladder tissues. Results: The results of bladder cystometry showed that the basal bladder pressure in NB-2W group was significantly increased,while it was slightly decreased but was still higher in NB-6W group than in the sham group (P<0.05).Basal bladder pressure was lower in NB-P-2W group than in NB-2W group,but was higher than that in the sham group; basal bladder pressure was lower in NB-P-6W group than in NB-6W group,but higher than that in the sham group (P<0.05).Compared with the sham group,the NB-2W and NB-6W groups had firstly increased and then decreased maximum cystometric capacity (MCC) (P<0.05).Compared with NB-2W group,NB-P-2W group had lower bladder leakage point pressure (BLPP),but higher MCC and bladder compliance (BC) (P<0.05).Compared with NB-6W group,NB-P-6W group had significantly lower BLPP but higher MCC and BC (P<0.05).HE and MASSON staining and ultrasound results showed that,with the extension of nerve transection time,bladder fibrosis gradually worsened,the bladder wall became rough and thickened,calculi were visible inside,and hydronephrosis gradually appeared; the degree of fibrosis in NB-P-2W and NB-P-6W groups was less than that in NB-2W and NB-6W groups,and no hydronephrosis was observed in the upper urinary tract.In addition,Western blotting and immunohistochemical results showed that NB-2W and NB-6W groups had significantly higher relative expression levels of Piezos,Collagen Ⅰ and α-SMA than the sham group (P<0.01),while NB-P-2W and NB-P-6W groups had lower relative expression levels of Piezos,Collagen Ⅰ and α-SMA than NB-2W and NB-6W groups (P<0.01). Conclusion: The increased expressions of mechanosensitive channels Piezos in NB young rats may be involved in the progression of bladder fibrosis,but its mechanism needs further study.

AIM:To analyze the compliance and curative effect of comprehensive vision training in patients with amblyopia. METHODS:A prospective study was conducted among 200 patients(294 eyes)with amblyopia who were treated in the hospital from July 2018 to August 2019. The patients were divided into a control group(98 patients, 140 eyes, traditional comprehensive vision training)and an experimental group(102 patients, 154 eyes, intelligent multi-dimensional comprehensive vision training)according to the random number table method. Curative effect, compliance, and the correlation between the two groups were observed.RESULTS:The overall response rate and compliance rate in the experimental group(93.5%, 45.1%)were higher than those in the control group(80.0%, 35.7%, all P<0.05). The curative effect was different in patients of different age, with different types and severity of amblyopia, different nature of fixation, and different compliance(all P<0.001). Age and the severity of amblyopia were negatively correlated with the curative effect(r=-0.342, -0.459, P<0.001), while compliance was positively correlated with the curative effect(r=0.378, P<0.001). Patients aged 3-6 had significantly better compliance, followed by those aged 7-10(P<0.05). Age was negatively correlated with treatment compliance(r=-0.398, P<0.001).CONCLUSION:Intelligent multi-dimensional comprehensive vision training can improve the compliance of patients with amblyopia, thereby achieving better curative effect. The curative effect is closely related to age, the type and severity of amblyopia, the nature of fixation and compliance. Compliance is related to age. Clinically, early treatment should be conducted bases on these features.

Objective:To investigate the relationship between metabolic syndrome (MS) and the risk of breast cancer in Chinese females.Methods:From May 2006 to December 2015, based on the Kailuan Women′s Dynamic Cohort,a total of 25 618 female employees and retirees of the Kailuan Group were included and followed. Questionnaire surveys, physical measurements and laboratory tests were used to collect baseline sociodemographic characteristics, height, weight, blood glucose, blood lipids, blood pressure, tumor incidence and outcome information. Cox proportional hazards regression models were used to analyze the relationship between MS and its components (body mass index, blood pressure, blood glucose and blood lipid) and the risk of breast cancer in females.Results:The age of 25 618 women was (47.65±12.02) years old and median follow-up time was 8.78 years; 235 new cases of breast cancer were detected, and the incidence density was 113.19/100 000 person-years. After adjusting for age, education, income, smoking status, drinking status and other factors, people who were overweight or obese had a higher risk of breast cancer, with HR (95% CI) about 1.47 (1.12-1.93), than those with normal body mass index. Compared with those without MS abnormal components, women with two MS abnormal components had an increased risk of breast cancer ( HR=1.70, 95% CI: 1.16-2.50). With the increase of the number of MS abnormal components, the risk of breast cancer increased gradually ( Ptrend value<0.05). Conclusion:Overweight/obesity and the number of abnormal components of MS can increase the risk of breast cancer in women.

[Abstract] Objective: To investigate the relationship between 18F-FDG PET/CT metabolic indicators and expression of immunocyte markers in lung adenocarcinoma patients, and to explore its significance in treatment and prognosis prediction for lung adenocarcinoma patients.Methods:Theclinicaldataof85lungadenocarcinomapatients,whoadmittedtoTianjinMedicalUniversityCancerInstituteand Hospital and underwent PET/CT examination from April 2008 to August 2014, were retrospectively analyzed. The expression levels of CD3, CD8, CD68, CD163, CD11c, Foxp3, PD-1 and PD-L1 were determined by immunohistochemistry. Correlations among immune markers (CD68+TAM), PET/CT metabolic parameters (SUVmax, SUVpeak and SUVmean) and tumor metabolic indicators (MTV , TLG) were analyzed using Pearson correlation analysis.The relationships between tumor metabolism, immune indicators and patients’survival outcomes were analyzed using the Kaplan-Meier method. Results: There was a remarkably negative correlation between SUVmax, SUVpeak, SUVmean and expression level of CD68+TAMs(r=-0.253,-0.265,-0.263,allP<0.05)butpositivecorrelationwithPD-1+TILs (r=0.427, 0.402, 0.395, all P<0.01) in lung adenocarcinoma patients. MTV and TLG were positively associated with Foxp3+ Tregs and PD-1+ TILs (r=0.313, 0.307, 0.29, 0.407, all P<0.01). Kaplan-Meier survival analysis showed that SUVmax, SUVmean, CD11c+DCs, PD-L1+ cells and TLG were all significantly associated with patients’prognosis (PFS or OS) (all P<0.05). Conclusion: Metabolism of tumor primary lesions is significantly correlated with tumor infiltrating immunocytes, and some of these indicators were associatedwithpatients’prognosis, suggesting that tumor metabolism and microenvironment immune status reflected by 18F-FDG PET/CTindicatorsmay have important reference value fortheimmunotherapyandprognosispredictionoflungadenocarcinoma patients.

Objective? To investigate the present situation of nurse's metabolic syndrome, and explore the correlation between diet, behavior and occupational stress and nurse's metabolic syndrome. Methods? In April to May 2015, using stratified cluster random sampling method, a total of 393 nurses in Fuzhou were investigated by physical examination, blood tests, Nurse Stressor Scale (NSS) and a general information questionnaire for metabolic syndrome and its influencing factors. Totally 393 questionnaires were distributed and 380 valid questionnaires were collected. Results? There were 54 cases of metabolic syndrome among 380 nurses, accounting for 14.21%. Logistic regression analysis showed that age, working age, occupational stress, sleep time, the amount of meat in diet, cooking oil were the risk factors of metabolic syndrome (P<0.05). The physical exercise and the quantity of vegetables in diet were the protective factors of metabolic syndrome (P<0.05). Conclusions? Unreasonable diet, inadequate exercise and occupational stress are the factors that affect the metabolic syndrome in nurses, which are related to their professional characteristics.

OBJECTIVETo evaluate the efficacy of intravascular ultrasound guided tranradial rotational atherectomy (RA) followed by drug eluting stent (DES) implantation in treating patients with heavily calcified coronary lesions.
METHODSClinical characteristics, coronary angiogram, intravascular ultrasound images, peri-procedure and follow-up data (including death , myocardial infarction and target lesion revascularization) of 44 patients treated with RA and DES implantation under the guidance of IVUS in our department from March 2011 to March 2013 were retrospectively analyzed. IVUS examination was carried out before RA, after RA and stent implantation to guide whether further RA or post dilatation was needed. According to the arc of calcification, the patients were divided into group A (90°-270°, 18 cases) and group B (271°-360°, 26 cases).
RESULTSIn A and B group, the arc of calcification was (195 ± 71)° in group A and (345 ± 23)° in group B (P < 0.01) , length of calcification was (34.4 ± 11.8) mm in group A and (20.0 ± 6.6) mm in group B (P < 0.05). Number of burrs used and size of largest burr used were similar between 2 groups (both P > 0.05). Acute cross sectional area gain after RA was (0.43 ± 0.32) mm in group A and (0.53 ± 0.38) mm² in group B (P > 0.05). After RA, there was significant decrease in the arc of calcification in group B compared with baseline ((324 ± 52)° vs. (345 ± 23)°, P < 0.05). The minimal lumen area and diameter were significantly increased after RA resulting in significant decrease in the plaque burden in both groups (all P < 0.05). The final minimal lumen area after stenting were similar between 2 groups (P > 0.05). Procedure success rate was 100% (44/44) without any major complications such as death, acute myocardial infarction and coronary perforation. During the (16.6 ± 6.3) months follow-up, there was 1 death in group A, 1 target lesion revascularization in group B and there was no acute myocardial infarction in the 2 groups.
CONCLUSIONHeavily calcified coronary lesions can be effectively and safely treated by transradial RA under the guidance of IVUS.
