Objective To investigate the effects of pneumonia on gastroesophageal reflux(GER)of neonates.Methods The distal 24 h esophageal pH monitoring was performed in 30 neonates with pneumonia and 30 controls.The number of reflux episodes,the number of refluxover 5 min,the longest time of reflux,the total time of pH

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 To study correlation between MRI signal intensity of the lumbar intervertebral disc and collagen content in the nucleus pulposus.Methods Thirty-one cases with lumbar intervertebral disc herniation(male 21,female 10)received percutaneous lumbar disketetomy.Thirty-one specimens of nucleous pulposus were obtained from percutaneous lumbar disketctomy procedure and collagen content in them was measured with reformed hydroxyproline measurement method.The signal intensity(SI) of lumbar intervertebral disc and cerebrospinal fluid was measured in T_2 WI sagittal image and then ratio of disc SI to cerebrospinal fluid SI was calculated.The Pearson analysis was used to analyze the correlation between the collagen content and SI ratio and disc SI on T_2 WI.Results Collagen content and SI ratio were (231.0?63.5)mg/g and 0.19?0.07,respectively.There was negative correlation between them (r=-0.61,P

Objective To evaluate the clinical outcome and relative factors of intervention treatment for atherosclerotic renal artery stenosis in elderly patients.Methods The clinical data of 79 patients diagnosed as atherosclerotic renal artery stenosis by angiography and treated by revascularization were analyzed.Results There were 55(69.6%)successes and 24(30.4%)failures in decreasing blood pressure and 28(35.4%)successes and 51(64.6%)failures in improving renal function after intervention treatment.Predictors of favorable outcome of intervention treatment in decreasing blood pressure were related to lower urine protein,higher glomerular filtration rate,higher systolic and diastolic blood pressure before treatment,lower resistance index(RI)of renal artery,and no complication of cerebral vascular diseases.Predictors of favorable outcome of intervention treatment in improving renal function were related with percentage of angiographic stenosis,category of antihypertension and lower urine protein.The logistic regression analysis showed that the percentage of angiographic stenosis was the most important predictor of intervention treatment for blood pressure control,age and level of serum creatinine before intervention treatment were the most important predictors of intervention treatment for improving renal faction.Conclusion Percentage of stenosis(≥85%),age(133 ?mol/L)can be used as the predictors of therapeutic success for renovascular stenosis in older patients.

OBJECTIVETo explore rest, cold compress and elevate (RICE) with rest, compress and elevate (RCE) without cold for the treatment of acute ankle sprain, in order to clear mid-term clinical effects.

METHODSEighty-nine patients with acute ankle sprains were collected from January 2013 to March 2014,including 30 males and 59 females aged from 18 to 60 years old with an average of 36 years old; the time from injury to hospital ranged from 3 to 24 h with an average of 9 h. All patients were divided into two groups according to visiting sequence. There were 45 patients in RICE group, and 45 patients in RCE groups. The main therapeutic effect index was evaluated by Karlsson scoring, and secondary therapeutic effect index was pain and satisfactory VAS scores. Safety index evaluated by adverse event.

RESULTSOn the 2nd weeks after injury, Karlsson score in RICE group was 44.66 ± 11.58, and 46.67 ± 8.52 in RCE group, while there was no statistical significance between two groups in Karlsson scores (P > 0.05). Karlsson score of two groups after treatment were higher than before treatment. There was no significantly meaning in pain and satisfactory VAS scores between two groups (P > 0.05). No adverse reaction were occurred between two groups.

CONCLUSIONCold compress did not receive much more final gains, and no evidence showed cold compress could affect recovery of joint function.

The tissue-specific and MeJA-induced transcriptional levels of BcUGT3 and BcUGT6 in Bupleurum chinense were analyzed in the present study. The transcriptional levels of BcUGT3 in root, leaf, flower and fruit were similar and they all were higher than those in stem. The transcriptional level of BcUGT6 was the highest in leaf and the lowest in flower among in all tested tissues. With non-treated adventitious roots as control, BcUGT6's transcriptional levels were elevated to nearly 2 folds for 2 h, 8 h, 24 h, 2 d and 4 d in MeJA-treated adventitious roots of B. chinense. It showed that the transcriptional level of BcUGT6 was slightly affected by MeJA. While, BcUGT3's transcriptional levels were gradually elevated, and till 4 d after MeJA treatment, the expression level was about 7 folds than that of non-treated control. Using pET-28a (+), the expressions of two genes was investigated. Induced by IPTG, the target proteins were expressed in E. coli and then purified. All the results obtained in the present study will be helpful for follow-up bio-function analysis of BcUGT3 and BcUGT6.

The inhibitory ratio (1%) of artificial musk on cyclooxygenase-2 (COX-2) was determined by enzyme immunoassay (EIA). The dose-effect relationship between concentrations of artificial musk and 1% was established. It was found that artificial musk had obvious inhibitory action on COX-2. The concentration for 50% of maximum inhibitory effect (IC50) was about 2.26 mg x mL(-1). There was a good relationship between the logarithm concentrations of artificial musk and 1% when the concentrations of artificial musk ranged from 0.31-20.0 mg x mL(-1). The results indicated that this EIA method could be applied to evaluate the anti-inflammatory activity of artificial musk quickly, conveniently, sensitively and exactly. This paper provided a novel method and foundational research for the bioassay of artificial musk.
