Objective To investigate the effect of complete revascularization strategy on the prognosis of elderly patients suffering from acute ST-segment elevated myocardial infarction(STEMI)complicated with multivessel disease(MVD). Methods A total of 390 elderly patients(over 60 years old)suffering from acute STEMI with MVD treated by clinical revascularization administration were enrolled for the study and divided into complete revascularization group(CR group,n=139)and non-complete revascularization group(NCR group,n=251). The effect of complete re-vascularization strategy on the prognosis was then analyzed by COX regression analysis. Results Compared with the NCR group,the patients of the CR group are younger and with a higher ratio of old myocardial infarction ,as well as the average number of stents ,and the mean value of total stent length is larger. The application of calcium channel blocker for post-operation patients is rarer as well. No significant difference can be found between the two groups on the ratio of post-operation all-cause mortality,cardiac mortality,nonfatal myocardial infarction,unplanned repeat revas-cularization. Multivariate COX analysis showed that the complete revascularization had no obvious difference on the prognosis of these patients be-tween the two groups. Conclusion There is individual diversity in the revascularization strategy choosing for elderly patients of acute STEMI alongside MVD;however,the prognosis is not significantly improved.

This study was aimed to evaluate the quality ofYuan-Hu Zhi-Tong (YHZT) tablet from different manufacturers by high performance liquid chromatography (HPLC) fingerprint. An HPLC method was developed to establish the fingerprint of 12 batches of YHZT from 10 manufacturers. The common peaks were confirmed by mass spectrometric analysis. Similarity analysis (SA), hierarchical cluster analysis (HCA) and principal component analysis (PCA) were applied to analyze the fingerprint chromatography. The results showed that there were 15 common peaks in which 12 components were from Corydalis Rhizoma and 3 from Radix Angelicae Dahuricae. The similar degrees of 12 batches of YHZT tablet were between 0.498 and 0.999. Based on the values, they could fall into three groups. The result of HCA showed that 12 batches of samples could be divided into 3 classes. The results of PCA indicated that the first three principal components (PCs) could represent the 15 common peaks. According to the scores of 3 PCs, 12 batches of samples could be divided into three categories. The classification result was mainly affected by the components of Corydalis Rhizoma. The classification results of three methods were basically the same. Based on the combination of three methods, 12 samples can be divided into three grades in the aspect of quality. It was concluded that the quality differences of YHZT tablet from different manufacturers were obvious. The combining application of three methods can be used in the evaluation on fingerprint of samples from different sources and influence factor analysis. It can be used as an effective method for quality evaluation.

This study was aimed to optimize extraction technology of Asperosaponin VI from Dipsaci Radix by re-sponse surface methodology (RSM). A single-factor test and Box-Behnken design (BBD) were employed to optimize three extraction variables, including extraction time (A), ethanol concentration (B), and the ratio of ethanol to materi-al (C). The transfer rate of Asperosaponin VI was used as the evaluation index. The results showed that the optimized conditions were A of 33.13 min, B of 51.58 %, C of 23.39 mL·g-1. Under these conditions, the transfer rate was 88.39 ± 0.212% (n = 3), which was well matched with the predicted transfer rate. It was concluded that RSM can be used for extraction optimization of ultrasonic extraction process for Asperosaponin VI. This method had certain prac-tical values.

In this research,a new phospholipid based monolith was fabricated by in situ co-polymerization of 1-dodecanoyl-2-(11-methacrylamidoundecanoyl)-sn-glycero-3-phosphoethanolamine and ethylene dimethacrylate to mimick bio-membrane environment.Excellent physicochemical properties of this novel monolith that were achieved included column efficiency,stability,and permeability.Moreover,the biomimetic monolith showed outstanding separation capability for a series of intact proteins and small molecules.In particular,it exhibited good potential as an alternative to the commercial immobilized artificial membrane(IAM)column(IAM.PC.DD2)for studying drug-membrane interactions.This study not only enriched the types of IAM stationary phases,but also provided a simple model for the prediction of phosphatidylethanolamine related properties of drug candidates.

Objective:To analyze the accuracy of lung ultrasound and chest X-ray in the diagnosis of neonatal pulmonary disease.Methods:We prospectively collected newborns that needed chest X-ray examination to diagnose pulmonary disease from twelve neonatal intensive care units across the country between June 2019 and April 2020.Each newborn was examined by lung ultrasound within two hours after chest X-ray examination.All chest X-ray and lung ultrasound images were independently read by a radiologist and a sonographer.When there was a disagreement, a panel of two experienced physicians made a final diagnosis based on the clinical history, chest X-ray and lung ultrasound images.Results:A total of 1 100 newborns were enrolled in our study.The diagnostic agreement between chest X-ray and lung ultrasound(Cohen′s kappa coefficient=0.347) was fair.Lung ultrasound(area under the curve=0.778; 95% CI 0.753-0.803) performed significantly better than chest X-ray(area under the curve=0.513; 95% CI 0.483-0.543) in the diagnosis of transient tachypnea of the newborn( P<0.001). The accuracy of lung ultrasound in diagnosing neonatal respiratory distress syndrome, meconium aspiration syndrome, pneumonia and neonatal pulmonary atelectasis was similar to that of chest X-ray. Conclusion:Lung ultrasound, as a low-cost, simple and radiation-free auxiliary examination method, has a diagnostic accuracy close to or even better than that of chest X-ray, which may replace chest X-ray in the diagnosis of some neonatal lung diseases.It should be noted that both chest X-ray and lung ultrasound can only be used as auxiliary means for the diagnosis of lung diseases, and it is necessary to combine imaging with the clinical history and presentation.

OBJECTIVE To develop a whole-process intelligent model of pharmaceutical care for peritoneal dialysis （PD） patients， and to provide a reference for clinical pharmacists to provide standardized PD pharmaceutical care. METHODS The pharmaceutical care mode of PD patients at home and abroad was investigated and analyzed. Based on the actual situation of the First Affiliated Hospital of Soochow University （hereinafter referred to as “our hospital”）， with “home→PD center outpatient→ inpatient department” as the main node， the recycling process of medication reconciliation was optimized. The whole-process intelligent pharmaceutical care model of PD was illustrated by improving the Chinese version of the drug-related problems （DRPs） classification tool， developing the corresponding pharmaceutical care process， and presenting specific cases. RESULTS Based on the medication therapy management （MTM） platform， our hospital had built a closed-loop PD whole-process intelligent pharmaceutical care model of “in-hospital pharmaceutical care （building document）-PD outpatient MTM-home pharmaceutical care （online App management）”. A “double cycle” workflow of “admission→discharge→outpatient” medication reconciliation cycle and “discovery-analysis-intervention-follow-up-record-evaluation” DRPs cycle was formed. CONCLUSIONS The establishment of the whole-process intelligent pharmaceutical care model for PD in our hospital provides experience for standardizing pharmaceutical care for PD patients， and can reduce DRPs.

OBJECTIVESince 1986, the reference of birth weight for gestational age has not been updated. The aim of this study was to set up Chinese neonatal network to investigate the current situation of birth weight in China, especially preterm birth weight, to develop the new reference for birth weight for gestational age and birth weight curve.

METHODA nationwide neonatology network was established in China. This survey was carried out in 63 hospitals of 23 provinces, municipalities and autonomous regions. We continuously collected the information of live births in participating hospitals during the study period of 2011-2014. Data describing birth weight and gestational age were collected prospectively. Newborn's birth weight was measured by electronic scale within 2 hours after birth when baby was undressed. The evaluation of gestational age was based on the combination of mother's last menstrual period, ultrasound in first trimester and gestational age estimation by gestational age scoring system.

STATISTICAL ANALYSISthe growth curve was drawn by using LMSP method, which was conducted in GAMLSS 1.9-4 software package in R software 2.11.1.

RESULTA total of 159 334 newborn infants were enrolled in this study. There were 84 447 male and 74 907 female. The mean birth weight was (3 232 ± 555) g, the mean birth weight of male newborn was (3 271 ± 576) g, the mean weight of female newborn was (3 188 ± 528) g. The test of the variables' distribution suggested that the distribution of gestational age and birth weight did not fit the normal distribution, the optimal distribution for them was BCT distribution. The Q-Q plot test and worm plot test suggested that this curve fitted the distribution optimally. The male and female neonatal birth weight curve was developed using the same method.

CONCLUSIONUsing GAMLSS method to establish nationwide neonatal birth weight curve, and the first time to update the birth weight reference in recent 28 years.
