Objective To summarize the complications of the single-port transumbilical laparoscopic pyeloureteroplasty.Methods From August 2009 to December 2014, 162 surgical procedures were performed in our institute with the single-port transumbilical laparoscopic pyeloureteroplasty.Medical records of each procedure were retrospectively evaluated.139 patients were male and 23 female, aged from 1 month to 14 years and the median age of 2 years.127 patients were operated on the left side and 32 on the right side.3 patients were operated on the bilateral side.All children were supplemented with preoperative ultrasound, renal dynamic imaging and MRU to identify the ureteropelvic junction obstruction.Intraoperative and postoperative complications were graded according to the Satava and Clavien classifications respectively.Major complications were defined as Satava grade Ⅱ or higher, and Clavien grade Ⅲ or higher.Results There was no injury of vascular or visceral organs and no blood transfusion, and there was no serious intraoperative complications.One hundred and forty-three cases were followed up, and 23 cases (16.1％)presented with postoperative fever (＞ 38 ℃C) (Clavien Ⅰ), 2 cases (1.4％) with urinary extravasation diagnosed by perirenal fluid collection(Clavien Ⅰ).All these cases recovered after being given symptomatic treatment.7 cases (4.9％) presented with postoperative repeated urinary infection (Clavien Ⅱ).5 cases received postoperative reoperation due to the obstruction of the anastomic site (Clavien Ⅲ b), and 2 cases were under debridement as the greater omentum was drawn out along with the negative pressure drainage tube(Clavien Ⅲ a).In summary, the incidence of severe postoperative complications was 4.9％.Conclusions Though there existed some postoperative complications of the single-port transumbilical laparoscopic pyeloureteroplasty, the incidence of serious complications was low and the overall prognosis could be good.

OBJECTIVE:To establish a way to monitor drug-induced liver damage by using hospital centralized management system for monitoring ADR.METHODS:Using self-designed computer program,the data of inpatients with abnormal ALT,AST and TBIL,admitted in the period from Dec. 2001 to Feb. 2002,were extracted from hospital HIS system of databa_se,and ADR and irrational drug-use were retrospectively analysed.RESULTS:There were 50 ADR incidents concerned with 30 kinds of drug and 11 cases receiving irrational medication concerned 10 kinds of drug.CONCLUSION:By this way,we can timely get the information of drug-induced liver damage and set up a new way for developing centralized ADR monitoring in hospital.

A high-performance liquid chromatography coupled ultraviolet （HPLC-UV） method was developed for a chemical fingerprint analysis of Viscum coloratura. Eighteen peaks were selected as the common peaks and Homoeriodictyol-7-O-β-D-apiosiyl-（1→2）-β-D-glucoside was used as a reference. The relative areas of common peaks were used for hierarchical clustering analysis and similarity calculation. Thirty-seven samples collected from different sources were classified into five groups. The similarities of 21 batches Viscum coloratura samples were beyond 0.90. The results obtained suggest that the chromatographic fingerprint can efficiently identify Viscum coloratum. Additionally, the fingerprints can then be used to evaluate the correlation between Viscum coloratura and hosts.

Methods: In this study, 267 matched pairs of AIS and controls were recruited. The participants underwent EMG measurements at their first presentation and did not receive any treatment for 6 months at which point they underwent EMG and radiographs. Early curve progression was defined as >5° in Cobb angle at 6 months. The root mean square of the EMG (rms-EMG) signal was recorded with the participants in sitting and back extension. The rms-EMG ratio at the upper end vertebrae, apical vertebrae (AV), and lower end vertebrae (LEV) of the major curve was calculated. Results: The rms-EMG ratio in the scoliosis cohort was high compared with that in the controls (sitting: 1.2±0.3 vs. 1.0±0.1, p<0.01; back extension: 1.1±0.2 vs. 1.0±0.1, p<0.01). An AV rms-EMG ratio in back extension, with a cutoff threshold of ≥1.5 in the major thoracic curve and ≥1.3 in the major lumbar curve, was a risk factor for early curve progression after 6 months without treatment (odds ratio, 4.1; 95% confidence interval, 2.8–5.9; p<0.01). Increases in side deviation (SD) (distance between the AV and the central sacral line) were related to a higher rms-EMG ratio in LEV of the major thoracic curve (baseline: rs=0.2, p=0.03; 6 months: rs=0.3, p<0.01). Conclusions An EMG discrepancy was detected in the scoliosis cohort, which was related to increases in SD in the major thoracic curve. The AV rms-EMG ratio in back extension was correlated with curve progression after 6 months of no treatment.

Antipsychotic medications are commonly used to treat schizophrenia,but they can have negative effects on lipid metabolism,leading to an increased risk of cardiovascular diseases,reduced life expectancy,and difficulties with treatment adherence.The specific mechanisms by which antipsychotics disrupt lipid metabolism are not well understood.Sterol regulatory element-binding proteins(SREBPs)are important transcriptional factors that regulate lipid metabolism.Proprotein convertase subtilisin/kexin type 9(PCSK9),a gene regulated by SREBPs,plays a critical role in controlling levels of low-density lipoprotein cholesterol(LDL-C)and has become a focus of research on lipid-lowering drugs.Recent studies have shown that antipsychotic drugs can affect lipid metabolism through the SREBP/PCSK9 pathway.A deep understanding of the mechanism for this pathway in antipsychotic drug-related metabolic abnormalities will promote the prevention of lipid metabolism disorders in patients with schizophrenia and the development and application of new drugs.
