Objective To investigate the efficacy and safety of transrectal ultrasound guided transurethral balloon dilation of the prostate (TUDP) for the treatment of benign prostatic hyperplasia (BPH).Methods A total of 23 men with BPH who had undergone TUDP were retrospectively analyzed,including 16 men with indwelling urinary catheters before the operation.During the TUDP,the prostatic apex and membranous urethra were dilated by inner balloon,and the prostatic urethra and bladder neck were dilated by outer balloon.The patients were followed up at the 1st,3rd,6th and 12th month after the operation,and the observation parameters included subjective symptoms,such as international prostatic symptom score (IPSS) and quality of life (QOL) score,and objective parameters,such as maximum flow rate (Qmax) and post-void residual (PVR).Results The operation time was 30-165 min,and the intraoperative hemorrhage volume was 5-50 ml.The IPSS scores at 1st,3rd,6th and 12th month after the operation were 10.4± 4.2,8.7±3.2,9.5±4.6 and 8.3±1.5 respectively,which were significantly decreased in comparison to the IPSS score (22.0±7.2) before the operation (P＜0.05).The QOL scores at 1st,3rd,6th and 12th month after the operation were 2.1±1.1,1.6±1.0,1.8±1.1 and 1.6±1.0 respectively,which were significantly improved in comparison to the QOL score (4.9±0.9) before the operation (P＜0.05).The Qmax at 1st,3rd,6th and 12th month after the operation were (10.5±3.4),(12.4±4.2),(10.9±3.9) and (12.7±4.6) ml/s respectively,which were significantly increased in comparison to the Qmax(1.9± 1.9 ml/s) before the operation (P＜0.05).There were 5,4,2 cases of urinary incontinence at the 1st,2nd and 3rd month after the operation,but they recovered at the 4th month follow-up.Besides,there were 3 cases suffered from epididymitis.Conclusion Transrectal ultrasound guided TUDP is a safe,effective and cheap option for the treatment of BPH,especially for the primary hospitals.

Objective To discuss the frequency of ventilator pipe replacement in ICU ward for reducing the frequency of VAP occurrence caused by bacterial colonization in ventilator-line. Methods 30 patients hospitalized to ICU ward from Janurary,2008 to June, 2009 who had mechanical-ventilation above 48h were randomly divided into group A, B and C with 30 patients in each group, then bacteria culture and strain analysis were employed for the pipeline sample of ventilator inspiratory side at the time point to be use and used mechanical ventilation for 1 day, 3 days and 7 days. Results There was no bacteria grew after ventilator-line sterilization, and positive ratio of bacterial culture in 1d, 3d and 7d were 46.66%,53.33% and 100.00%, respectively. Conclusions The frequency of ventilator pipe replacement should be shortened in patients with abdominal infection, to replace every 3 days is suitable in ICU where infectious patients gathered.

Objective To evaluate the feasibility,security and efficiency of general anaesthesia compared with regional anaesthesia for minimally-invasive thyroid surgery(MITS)with short-stay discharge.Methods 103 cases undergoing MITS with short-stay discharge from Jan.2013 to Jun.2013 in Fuzhou General Hospital were collected.54 patients were operated under regional anaesthesia and 49 under general anaesthesia.All variables of patients including demographic characteristics,vital signs (blood pressure,heart rate,blood glucose) during the operation,duration and type of operation,postoperative complications,difficulty in airway management and anesthesia consumption were recorded and analyzed.Results There was no difference in respect to level of blood glucose,length of hospital stay,discharge time,patient or operator satisfaction rate,anesthesia or operation complications rate between the two groups.Blood pressure (T1:(90 ± 7.0) vs (79 ± 8.3) mmHg,T2:(88 ± 6.8) vs (80 ±7.6) mmHg,P ＜0.05) and heart rate(T1:(130 ± 18.2) vs(101 ± 12.0)/min,T2:(120 ± 19.7) vs(103 ± 13.3)/min,P ＜ 0.05)level were higher,while the recovery time of anesthesia((0.3 ± 0.14)vs(0.8 ± 0.35)h,P ＜ 0.05)) and anesthesia consumption ((1350 ± 78) vs (2580 ± 220) yuan,P ＜ 0.05)) were lower in the regional anaesthesia group compared with those in the general anaesthesia group.Conclusions Both general anaesthesia and regional anaesthesia for MITS with short-stay discharge are safe and effective.General anesthesia has less psychological trauma,while regional anaesthesia has shorter recovery time and lower anesthetic consumption.

OBJECTIVETo explore material basis of the pharmacological differences between the roasting and pro-roasting Raphani Semen.

METHODThe two new sulfur-containing compounds (A209 and B221) were found changed after processing in the water decoction. The common precursor-C3 of A209 and B211 and the precursor of C3 were seperated and purified. Their transforming relationship was proved.

RESULTThe result showed that glucosinolates could decompose into sulforaphane and transform into A209 and B221 further in the boiling process.

CONCLUSIONThis study provides some experimental evidences for revealing the mechanism of Raphani Semen processing.

Gastric cancer (GC) is one of the most frequent malignant tumors. In order to systematically characterize the cellular and molecular mechanisms of intestinal GC development, in this study, we used 22 K oligonucleotide microarrays and bioinformatics analysis to evaluate the gene expression profiles of GC in 45 tissue samples, including 20 intestinal GC tissue samples,20 normal appearing tissues (NATs) adjacent to tumors and 5 noncancerous gastric mucosa tissue samples. These profiles allowed us to explore the transcriptional characteristics of GC and determine the change patterns in gene expression that may be of clinical significance. 1519 and 1255 differentially- expressed genes (DEGs) were identified in intestinal GC tissues and NATs, respectively, as determined by Bayesian analysis (P < 0.001). These genes were associated with diverse functions such as mucosa secretion, metabolism, proliferation, signaling and development, which occur at different stages of GC development.

Objective:To explore the influences of different lying positions on vital signs and comforts in patients with tracheal intubation removed after intestinal fistula surgery.Methods:From October 2018 to June 2019, convenience sampling was used to select 150 patients with intestinal fistula surgery after general anesthesia in Intensive Care Unit of the General Hospital of Eastern Theater Command were selected as the research object. After waiting for the patient to wake up from anesthesia, the tracheal intubation was removed, and the lying position was changed after normal spontaneous breathing through the nose. Patients were randomly divided into 5 groups, 30 cases in each group. Group A was in the supine position; group B was in the lying position with the head of the bed raised by 15°; group C was in the lying position with the head of the bed raised by 30°; group D was in the lying position with the head of the bed raised by 45°; group E was in the lying position with the head of the bed raised by 15° to 45 °. At the beginning, the head of the bed was shaken to 15 °; and after two hours, the head of the bed was shaken to 30 °, and after another two hours, the head of the bed was shaken to 45 °. After 5 groups of patients fixed the angle of the lying position, when the patient complained of discomfort or the body position changed spontaneously, the patient changed the lying position. The duration of the lying position, uncomfortable symptoms and pain degree of abdominal incision were compared among 5 groups.Results:Patients with tracheal intubation removed after intestinal fistula surgery had a longer persistence in the 15° and 30° lying positions within 6 hours, respectively (72.27±12.41) min and (69.37±9.10) min. There were statistically significant differences in the persistence time of 5 different lying positions ( P<0.01) . The number of patients in group B and C with waist pain was less, and there were more patients with painless incisions, and there were statistically significant differences among 5 groups ( P<0.05) . Conclusions:Among patients with tracheal intubation removed and normal spontaneous breathing through the nose after intestinal fistula surgery, the 15° to 30° lying position within 6 hours after the operation can prolong the patient's adherence to the lying position, reduce the incidence of abdominal incision pain and waist pain, and reduce the probability of dizziness, nausea and vomiting.
