Objective To investigate the relationship between abdominal aortic calcification (AAC) and outcomes in maintenance hemodialysis (MHD) patients. Methods One hundred and seventy MHD patients in the dialysis center of the Second Hospital of Tianjin Medical University from June 2014 and October 2014 were enrolled prospectively. Abdominal aortic calcification (AAC) was measured using AAC score (AACS) by abdominal lateral plain radiography. According to the AACS, the patients were divided into mild AAC (AACS<5) group and severe AAC (AACS≥5) group for comparison, and Kaplan?Meier analysis was used to compare their survival rates. Multivariable COX regression models were used to determine the risk factors of all?cause mortality and cardiovascular disease mortality in MHD patients. Results Severe AAC (AACS≥5) was present in 28.2%(48/170) patients. The median follow?up duration was 25.6 (22.0, 26.0) months. During the follow?up, 6 patients (4.9%) in AACS<5 group and 14 patients (29.2%) in AACS≥5 group died. Kaplan?Meier analysis showed that patients in AACS≥5 group had higher all?cause mortality rate and cardiovascular disease mortality rate as compared with patients in AACS<5 group (χ2=9.746 ,P=0.002; χ2=9.697 ,P=0.002). Multivariate COX regression analysis demonstrated that high AACS (HR=4.373, 95%CI 1.562?7.246, P=0.005) and hypoproteinemia (HR=0.886, 95%CI 0.797?0.985, P=0.025) were independent risk factors for all?cause mortality, while hypoproteinemia (HR=0.829, 95%CI 0.718?0.956, P=0.010) and low 1,25(OH)D3 (HR=0.769, 95% CI 0.627 ? 0.944, P=0.012) were independent risk factors for cardiovascular disease mortality. Conclusions AAC is significantly associated with overall survival in MHD patients. To further evaluate the relationship between AAC and outcomes in MHD patients, multi?center and long term follow up studies of large sample size are necessary.

OBJECTIVETo investigate the expression of long non-coding RNA-HOTAIR in prostate cancer cells and its effects on the growth and metastasis of the cells.

METHODSUsing quantitative reverse-transcription PCR (qRT-PCR), we determined the relative expression of HOTAIR in the normal human prostate epithelial cell line RWPE-I and prostate cancer cell lines PC-3 and DU145. We detected the effects of HOTAIR on the cell cycle and invasiveness of prostate cancer cells by RNA interference, flow cytometry, and Transwell mitration assay.

RESULTSThe expressions of HOTAIR in the PC3 and DU145 cells were increased 3.2 and 5.7 times, respectively, as compared with that in the normal RWPE-1 cells. After si-HOTAIR interference, the prostate cancer cells were arrested in the G2 phase and downregulated in the G1 phase. The invasive ability of the prostate cancer cells was evidently inhibited, with the inhibition rates of 32% and 44% of the PC3 cells and 43% and 34% of the DU145 cells for si-HOTAIR1 and si-HOTAIR2, respectively.

CONCLUSIONIncRNA HOTAIR is highly expressed in prostate cancer, which is associated with the growth and invasiveness of prostate cancer cells. HOTAIR is potentially a novel marker for the diagnosis and prognosis of prostate cancer.

Objective:Taking Chongyang county of Hubei Province as an example, the paper describes the in-tegration of the maternal and child health ( MCH) and family planning ( FP) service system and analyses the key ele-ments to provide reference for promoting integration. Methods: qualitative interviews and quantitative questionnaire were used to collect data. The software QSR Nvivo 8. 0 and SPSS 17. 0 were used for qualitative and quantitative data analysis. Results:Based on the correct understanding of integration, Chongyang implements the supporting policies actively, maintains the original compensation mode unchanged, follows the principle of“no reducing headcounts and no downsizing” strictly, promotes the merger of institutions rapidly, adjusts the service contents and methods reasona-bly, and integrates the maternal and child and family planning information platform. Conclusion:The correct concept of integration, appropriate staffing, and stable funding in Chongyang provide rich experiences for future research. However, there is room for improvement in staffing, incentive mechanisms, service content, and forms.

Objective To investigate the effects of early nasal intermittent positive pressure ventilation (NIPPV) compared with early continuous positive airway pressure (NCPAP) in low birth weight preterm infants with respiratory distress syndrome (RDS).Methods We performed a prospective,randomized controlled trial involving 364 low birth weight preterm infants with respiratory distress syndrome within 6 hours of birth.The infants were randomly assigned to NIPPV (n=188) or NCPAP (n=176) groups.Non invasive ventilation was initiated in the neonatal intensive care unit (NICU).The rate of mechanical intubation (within 3 days or 7 days),the use of pulmonary surfactant (PS),the rate of complications and mortality were compared between the two groups.Mann Whitney U,t and Chi-square tests were used for statistical analysis.Results The average time of invasive mechanical ventilation in NIPPV group were lower than that in NCPAP group[2.0 (1.0-4.0) d vs 7.0 (3.0-8.5) d,U=-3.457,P=0.001].The need for intubation and mechanical ventilation by day 3 and day 7 in the NIPPV group were less than those in the NCPAP group [day 3:4.8％ (9/188) vs 10.8％ (19/176),x2=4.621,P=0.032; day 7:9.0％ (17/188) vs 16.5％ (29/176),x2=4.551,P=0.033].In the NIPPV group,infants who got PS therapy was less than that in the NCPAP group [3.2％ (6/188) vs 8.5％ (15/176),x2=4.752,P=0.029].There was no significant difference in the fatality rate between the NIPPV and the NCPAP group [12.8％ (24/188) vs 10.8％ (19/176),P ＞ 0.05].There were no significant difference in the incidence of air leak,intracranial hemorrhage,periventricular leukomalacia,retinopathy of prematurity,necrotizing enterocolitis,patent ductus arteriosus,and bronchopulmonary dysplasia between the NIPPV group and the NCPAP group.Conclusion Among low birth weight prcterm infants with RDS,the early use of NIPPV reduces the need for PS,intubation and invasive ventilation compared with NCPAP.

Objective In order to investigate the relationship between hearing loss and diabetic peripheral neuropathy( DPN ) via comparing the pure tone thresholds and vibration perception threshold(VPT) in type 2 diabetic patients and control person without diabetes. Methods 173 subjects including 138 type 2 diabetic patients(DM)and 35 non-diabetes controls were examined for VPT and hearing threshold. Nerve conducting velocity ( NCV )including sensory nerve conducting velocity( SCV )and motorial nerve conducting velocity( MCV )of diabetic patients were determined. The participants were divided into three groups: control group (n = 35 ), DM group without peripheral neuropathy( non-PN group, n = 74 ), and DM group complicated with peripheral neuropathy (PN group,n = 64 ). The clinical characteristics, biochemical parameters , the incidence of sensorineural hearing loss ( SNHL),pure tone threshold, and VPT were compared among three groups. At last, the relationship between hearing thresholds and NCV were analyzed. Results The incidence of hearing impairment of sensorineural type was 29.69% in PN group, which was significantly higher than that of non-PN group( 17.57% )and control group( 17. 14% ). There was significant differences in age, duration of diabetes, glycolated hemoglobin (HbA1c), glycolated serum albumin ( GA), Fasting blood glucose( FPG), 2h postprandial blood glucose( PPG), VPT, and hearing threshold among the three groups( all P＜0. 05 ). The value of hearing threshold increased significantly( all P＜0. 05 ) in 3 VPT subgroups with VPT≤ 15 V, VPT 16-25 V, and VPT ＞25 V. The Spearman correlation analysis showed median NCV was negatively correlated with hearing threshold on 1.00, 2.00, 4. 00, and 8. 00 kHz ( All P ＜ 0. 05 ). The logistic regression analysis indicated that the age( regression coefficient =0. 088, P＜0. 01 ) was the independent risk factor of SNHL, median nerve MCV ( regression coefficient = -0. 135, P = 0. 046 ) was the important influencing factor of SNHL. Conclusion Diabetic patients are more likely to suffer from impaired middle-frequency and high-frequency hearing, DPN in patients is often complicated with hearing impairment. Age and median nerve MCV were major risk factors of SNHL in diabetic patients.

Objective To study the effect of balloon dilatation therapy on dysphagia caused by cricopharyn- geal achalasia.Methods Ten cases of dysphagia were diagnosed as cricopharyngeal achalasia by videofluoroscopic swallowing study(VFSS).A 14~* urethral catheter was inserted into the esophagus and an amount of water was injec- ted into the balloon of the urethral catheter to make it turgid.Then the catheter was pulled upwards and passed through the stricture of esophagus to dilatate the cricopbarygeus muscle.Meanwhile,low frequency electrical stimula- tion was used and combined with functional training of the organs related to deglutition and ingestion.The results be- fore and after the treatment were evaluated.Results After 19.7 times of dilatation therapy,the content of water in- jected into the balloon was increased from 2.65?0.91 ml to 8.20?0.92 ml.Cricopharyngeal achalasia was alle- viated significantly(P

Objective:To explore the distribution characteristics of respiratory pathogens in patients with community-acquired pneumonia in Lianyungang.Methods:A total of 612 patients admitted to the second people′s Hospital of Lianyungang City because of community-acquired pneumonia (CAP) in 2019 were selected as subjects. Sputum or pharyngeal swabs were collected to extract nucleic acids, and 13-fold nucleic acids of respiratory pathogens were detected by PCR capillary electrophoresis fragment analysis. SPSS statistical software and GraphPad5.0 statistical mapping software were used for statistical analysis.Results:The physical examination rate of respiratory pathogens in the adult group was 82.0% in winter, 48.4% in spring, 28.0% in autumn, 20.0% in summer, χ 2=38.473, P=0.000. The positive rate of nucleic acid detection was significantly different in different seasons, among which the physical examination rate of respiratory pathogens in winter was the highest. The physical examination rate of respiratory pathogens in the juvenile group was 86.0% in spring, 76.2% in winter, 71.3% in summer and 66.7% in autumn, χ 2=7.946, P=0.047 . The positive rate of nucleic acid detection was calculated according to gender grouping. The comparison of nucleic acid positive rate between adult group and juvenile group in different seasons: 86.0% vs 48.4% in spring, χ 2=19.436, P=0.000; 71.3% vs 20.0% in summer, χ 2=22.180, P=0.000; 66.7% vs 28.0% in autumn, χ 2=13.485, P=0.000; 76.2% vs 82.0% in winter, χ 2=0.758, P=0.384. Except in winter, the detection rate of nucleic acid of pathogens in the juvenile group was significantly higher than that in the adult group. Conclusions:The nucleic acid detection rate and etiological distribution characteristics of respiratory pathogens are different in patients with community-acquired pneumonia in different seasons and different age groups. 13 kinds of multiple detection methods of respiratory pathogens can provide favorable laboratory data support for the diagnosis and treatment of clinical CAP patients.

To study the effect of plant-derived smoke water on the accumulation of biomass and active substance of Salvia miltiorrhiza f. alba, seedlings of S. miltiorrhiza were treated with different concentrations of smoke water (1:500, 1: 1 000, 1: 2 000). The fresh weight and dry weight of underground part, the number of split-root, maximum root diameter, average root diameter, average root length, the content of lipophilic components and water-soluble components were measured. Results showed that fresh weight and dry weight of underground part were respectively improved by 98.01%, 44.32% and 85.71%, 28.57% with significant difference by smoke water treatment with concentration of 1: 500 and 1: 1 000. Maximum root diameter and dry weight of underground part were respectively enhanced by 58.44% and 85.71% by smoke water with concentration of 1:500. The content of tanshinone I and tanshinone II(A) were improved by smoke water treatment, however there were no significantly difference on the content of cryptotanshinone and dihydrotan shinone. This study indicates that smoke water treatment could be used to improve the accumulation of biomass and active substance content of S. miltiorrhiza f. alba, which could provide new ideas for its green cultivating.
