Methods A nursing checklist for continuous renal replacement therapy was de-signed through reviewing guidelines and literatures. The checklist was used in ICU patients treated with continu-ous renal replacement therapy,and nursing situation (including operation time,operation quality,etc.) was compared before and after application of the checklist. Results After applying the nursing checklist for continuous renal re-placement therapy,the nursing procedures were standardized,the operation time was reduced,and operation quality was improved. Conclusion The application of nursing checklist in nursing management of continuous renal replace-ment therapy helped to standardize continuous renal replacement therapy operating procedures,improve efficiency and quality at work,and ensure patient safety.

Objective: To reveal the clinical and genetic features of neonatal/infantile epileptic disorders caused by KCNQ2 mutations and to provide a clue for the treatment and prognosis evaluation. Methods: Twenty-two patients were collected in the Department of Pediatrics, Peking University First Hospital from April 2007 to July 2016.The phenotype-genotype analysis was conducted of the neonatal/infantile epileptic patients in whom a KCNQ2 mutation was identified by the targeted next generation sequencing. Results: Twenty-two de novo KCNQ2 missense mutations from 22 patients with neonatal/infantile epileptic disorders were found.These patients had an onset of epilepsy in early infancy (median age: 2 days). The seizure type of the first onset was mainly focal seizure.Atypical absence epilepsy, a novel phenotype of KCNQ2 mutation-induced epilepsies was found.The mortality of these patients was high, as 5 patients of the 22 patients died in the follow-up period, 4 of which might result from sudden unexpected death in epilepsy.In the 22 patients, 8 patients with anti-epileptic monotherapy became seizure-free.Of the 8 patients with a monotherapy, 3 patients were treated with valproic acid and no clinical onset was observed. Conclusions This study expands the phenotype of KCNQ2-related epileptic disorders.These patients have high mortality.Valproate acid is the potentially effective monotherapy for these patients.

ObjectiveTo explore the clinical efficacy of Huanglian Jiedutang as an adjunctive treatment for acute cerebral infarction complicated with gastric motility disorder. MethodSixty patients with acute cerebral infarction complicated with gastric motility disorder with fire toxin syndrome were randomly divided into a western medicine control group （control group） and a traditional Chinese medicine （TCM） combined treatment group （observation group）， with 30 cases in each group. The control group received basic treatment for cerebral infarction and relevant western medical symptomatic treatment based on the patients' gastrointestinal symptoms. The observation group received Huanglian Jiedutang in addition to the treatment provided to the control group. The treatment course was 7 days. Neurological deficit scores and gastrointestinal dysfunction scores were assessed in both groups before treatment and on the 4^th and 7^th days of treatment. Gastrointestinal electrographic parameters， serum citrulline （CIT）， and motilin （MTL） levels were measured in both groups before treatment and on the 7^th day of treatment. Clinical efficacy was compared between the two groups. ResultCompared with the baseline in both groups， the neurological deficit scores and gastrointestinal dysfunction scores were significantly reduced on the 4th and 7^th days of treatment （P<0.05）. The reductions in these scores were more significant on the 7^th day compared with those on the 4^th day of treatment （P<0.05）. On the 4^th and 7^th days of treatment， the observation group showed a significantly greater reduction in neurological deficit scores and gastrointestinal dysfunction scores compared with the control group （P<0.05）. On the 7th day of treatment， compared with the baseline， both groups showed a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. On the 7th day of treatment， compared with the control group， the observation group had a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. After 7 days of treatment， the total effective rate in the observation group was 90.00% （27/30）， higher than 76.67% （23/30） in the control group， but the difference was not statistically significant. ConclusionAdjunctive treatment with Huanglian Jiedutang can effectively improve the symptoms of neurological function impairment and gastrointestinal dysfunction in patients with acute cerebral infarction complicated with gastric motility disorder， increase gastric antral and gastric body electric wave amplitudes， improve gastric motility disorder， and increase serum CIT and MTL levels， thereby improving the imbalanced secretion function of the gastrointestinal tract.

OBJECTIVE: To evaluate the changes of cardiac structure and function and their risk factors in elderly patients with obstructive sleep apnea syndrome (OSA) without cardiovascular complications. METHODS: Eighty-two elderly OSA patients without cardiovascular disease admitted between January, 2015 and October, 2016 were enrolled in this study. According to their apnea-hypopnea index (AHI, calculated as the average number of episodes of apnoea and hypopnoea per hour of sleep), the patients were divided into mild OSA group (AHI < 15) and moderate to severe OSA group (AHI ≥ 15). The demographic data and the general clinical data were recorded and fasting blood samples were collected from the patients on the next morning following polysomnographic monitoring for blood cell analysis and biochemical examination. Echocardiography was performed within one week after overnight polysomnography, and the cardiac structure, cardiac function and biochemical indexes were compared between the two groups. RESULTS: Compared with those with mild OSA group, the patients with moderate to severe OSA had significantly higher hematocrit (0.22±0.08 CONCLUSIONS Cardiac diastolic function impairment may occur in elderly patients with moderate or severe OSA who do not have hypertension or other cardiovascular diseases, and the severity of the impairment is positively correlated with AHI.

ObjectiveTaking Shengxuebao as the model traditional Chinese medicine（TCM）， this study aims to explore the methodologies and transfer patterns in the composition changes of TCM compound preparations from liquid to solid dosage forms. MethodBased on the previously established ultra-high performance liquid chromatography（UPLC） qualitative and quantitative methods for Shengxuebao， the fingerprint profiles of three preparations of Shengxuebao（homemade decoction， commercially available granules and mixtures） were established， and nineteen components were quantitatively analyzed. The similarities of fingerprint profiles among these three preparations were assessed using the Similarity Evaluation System for Chromatographic Fingerprint of TCM（2012 edition） and the total quantum statistical moment similarity method， respectively. The molecular connectivity index （MCI） and the average molar MCI of the chemical components in the three preparations were calculated. Seventy-two MCI values across 0-8 orders， including 8 subclasses， were calculated. The average molar MCI of 0-3 orders was used to study the "imprint template" structural characteristics and transfer patterns of the medicinal component groups. ResultThe similarities of the fingerprint profile of the decoction with those of the control， granules， and mixtures were 0.971， 0.888 and 0.799， respectively， indicating that the chemical composition of the granules and mixtures differed from that of the decoction， and that the 19 components were able to basically respond to the overall situation of the component group of Shengxuebao decoction. The total mass fractions of the detectable major components in Shengxuebao decoction， granules and mixtures was measured to be 5.498 6， 2.282 0， 1.416 6 mg·g^-1， respectively. The average molar MCI of 0-3 orders showed a gradual decrease across the three preparations， with the trend of decoction>granules>mixtures， indicating subtle changes in the overall structural characteristics of the chemical components in the samples of the three preparations. ConclusionAmong the three formulations of Shengxuebao， the traditional decoction contained the highest variety and quantity of components and carried the most substantial amount of component information， with a decreasing order observed in the granules and mixtures. This study further validates that traditional decoction is a reliable and fundamental dosage form， providing a reference for the modernization of TCM dosage forms and the quality consistency evaluation of compound preparations.

OBJECTIVE: To investigate the correlation between the severity of obstructive sleep apnea syndrome (OSAS) and red cell distribution width (RDW) in elderly patients. METHODS: A cross-sectional study was conducted among 311 elderly patients diagnosed with OSAS in the snoring clinic between January, 2015 and October, 2016 and 120 healthy controls without OSAS from physical examination populations in the General Hospital of PLA. The subjects were divided into control group with apnea-hypopnea index (AHI) <5 (=120), mild OSAS group (AHI of 5.0-14.9; =90), moderate OSAS group (AHI of 15.0-29.9; =113) and severe OSAS group (AHI ≥ 30; =108). The clinical characteristics and the results of polysomnography, routine blood tests and biochemical tests of the subjects were collected. Multiple linear regression analysis was used to examine the correlation between OSAS severity and RDW. RESULTS: The levels of RDW and triglyceride were significantly higher in severe OSAS group than in the other groups ( < 0.01). The levels of fasting blood glucose and body mass index were significantly higher in severe and moderate OSAS groups than in mild OSAS group and control group ( < 0.05 or < 0.01). Multiple linear regression analysis showed that AHI was positively correlated with body mass index (β=0.111, =0.032) and RDW (β=0.106, =0.029). The area under ROC curve of RDW for predicting the severity of OSAS was 0.687 (=0.0001). CONCLUSIONS The RDW increases as OSAS worsens and may serve as a potential marker for evaluating the severity of OSAS.
