ABSTRACT
@#Objective To systematically evaluate the safety and efficacy of percutaneous closure of atrial septal defect (ASD) guided by echocardiography alone versus fluoroscopy. Methods The databases of PubMed, The Cochrane Library, EMbase, VIP, Wanfang Data and CNKI from January 2000 to October 2021 were searched by computer for relevant research literature. Two reviewers independently screened the literature, extracted the data and evaluated the quality according to the inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.4 software. Results A total of 19 cohort studies and 1 randomized controlled study were collected, including 2 825 patients. The Newcastle-Ottawa Scale score for cohort studies was≥7 points. Meta-analysis showed that there was no statistical difference in the operative success rate (RR=1.01, 95%CI 1.00 to 1.02, P=0.17), incidence of occluder displacement/shedding (RR=0.77, 95%CI 0.26 to 2.27, P=0.63), incidence of arrhythmia (RR=0.50, 95%CI 0.21 to 1.14, P=0.10), incidence of pericardial effusion (RR=0.98, 95%CI 0.32 to 2.98, P=0.97), operative time (MD=–0.23, 95%CI –7.56 to 7.10, P=0.95) or cost (SMD=–0.39, 95%CI –1.09 to 0.30, P=0.27) between the two groups. The echocardiography group reduced the incidence of total postoperative complications (RR=0.42, 95%CI 0.30 to 0.60, P<0.001) and residual shunt (RR=0.70, 95%CI 0.50 to 0.98, P=0.04), and shortened length of hospital stay (MD=–0.43, 95%CI –0.77 to 0.09, P=0.01). Conclusion Compared with traditional fluoroscopy-guided percutaneous closure of ASD, echocardiography guidance alone is equivalent in terms of operative success rate, major postoperative complications, operative time and total cost, but it reduces the incidence of total postoperative complications and residual shunt, and has a shorter length of hospital stay.

ABSTRACT
Objective To assess the capability of serum and urine neutrophil gelatinase-associated lipocalin (NGAL) in predicting acute kidney injury (AKI) in septic patients.Methods From July 1, 2014 through December 31, 2014, a prospective observational study of septic patients without AKI was carried out in Renmin Hospital, Tianjin Hospital, and Nankai Hospital, Tianjin.The patients with AKI which was developed after admission to intensive care unit (ICU) were assigned to AKI group and the patients without AKI were assigned to non-AKI group.Clinical data and serum and urine sample were collected at the admission, and at 12, 24, 36, 48, 60, 72 ,84 and 96 hours after admission for detecting creatinine and NGAL.The measurement data accorded with normal distribution were used for t test or variance analysis of repeated measures;comparison of measurement data in non-normal distribution was carried out using the Mann-Whitney U test or Fridman test;comparison of count data was performed using Fisher exact probability method.ROC curve of serum or urine NGAL was plotted and the diagnostic values of serum or urine NGAL in predicting AKI were assessed by calculation of the area under the receiver operating characteristic curve (AuROC).Results Fifty septic patients were included.Thirty-five patients were in AKI group and fifteen in non-AKI group.The median age of AKI group was 73 and the median age of non-AKI group was 60 (IQR, 47-82).The urine NGAL (uNGAL) concentration in AKI group was higher than that in non-AKI group at the every interval and serum NGAL (sNGAL) was higher in AKI group than that in non-AKI group at only first twointervals.The uNGAL showed the capability of prediction for AKI progression at the 48 hour (AuROC=0.83,95% CI:0.70-0.97), 36 hours (AuROC=0.75,95%CI:0.59-0.91), 24 hours (AuROC=0.83,95%CI:0.70-0.95), 12 hours (AuROC=0.73,95%CI:0.60-0.88) prior to AKI occurred.The sNGAL showed capability of prediction at the 48 hours (AuROC=0.69,95%CI:0.51-0.88), 36 hours (AuROC=0.69,95%CI:0.52-0.87) prior to AKI occurred.Conclusions The sNGAL and uNGAL both were useful biomarker that predicted development of AKI in early stage.But the performance of sNGAL was slightly inferior to that of uNGAL for predicting development of AKI.
ABSTRACT
In recent years,considerable progress has been made in the treatment of hematologic malig-nancies.However,most patients will eventually relapse and suffer from severe side effects caused by chemotherapy or radiation.Thus,as a well tolerated,safe,effective and innovative therapy,adoptive cellular immunotherapy e-merges at this very moment.This therapy can kill tumors or control recurrence by reinfusing the in vitro amplifi-cated or treated immune effective cells into the patients.It has been actively used in the treatment of various he-matological malignancies and achieved significant effects,which brings hope for more and more patients with re-lapsed or refractory hematological diseases.
ABSTRACT
Objective ①Observing urinary neutrophil gelatinase-associated lipocalin (uNGAL)'s concentration variation under the intervention of sepsis; ②Evaluatingu NGAL' s diagnostic value for early acute kidney injury (AKI).Method Fifty-six SD (Sprague Dawley) rats were randomly (random number) divided into four groups,including 16 rats in model group (CLG),16 rats in Xuebijing group (XBG),16 rats in Huangqi and Chaihu injection jointly applied group (HCG),and 8 rats in sham operation group (SOG).The septic models in CLG group,HCG group and XBG group were established by cecal ligation and puncture (CLP).Then,the rats in HCG group was treated with intraperitoneal injectionby Huangqi and Chaihu injections; the XBG group was treated with intravenous injection by Xuebijing injection; the SOG group was treated with open surgery without CLP.After the CLP,serial urine and serum samples were obtained at baseline (just prior to operation),6 h,12 h,18 h,24 h,36 h,48 h,and 72 h,and were measured by sCr,uCr,uNa,and uNGAL.The line graph of uNGAL' s concentration variation was plotted,based on the time.Diagnostic characteristics of urinary NGAL in predicting AKI were assessed by calculating the area under the receiver operating characteristic curve (AUC).Results After the CLP,the uNGAL of sepsis model rats increased quickly within 6 hours.The time points of each group model reaching their peak were 6 hours after CLP in CLG groupand 24 hours after CLP in HCG group and XBG group.These groups' uNGAL all decreased quickly after the peak.The cuNGAL of sepsis model rats was increased quickly within 6 hours after CLP,reached its peak at 24 hours after CLP.In CLG group,the line graphs of uNGAL or cuNGAL were almost overlapped.There is little difference in the concentration of uNGAL or cuNGAL at each time point (uNGAL:6h,t=0.691; 12h,t=1.627; 18 h,t=0.511,cuNGAL:6h,t =0.371 ; 12 h,t =0.474; 18 h,t =-1.187.Statistical significance of all above value was P ＞0.05).InXBG group,the line graph of uNGAL and cuNGAL were not overlapped,but difference between uNGAL and cuNGAL concentration at each time point was not significant (uNGAL:6 h,t =1.222 ; 12 h,t =1.178 ; 18h,t=1.272; 24h,t=0.918; 36h,t =0.442.cuNGAL:6 h,t =1.482; 12 h,t =1.314; 18 h,t=1.280; 24 h,t =0.280; 36 h,t =0.467.Statistical significance of all above value was P ＞ 0.05).In HCG group,uNGAL of AKI rats were higher than non-AKI rats at each time points since 6 hours later (6 h,t =2.351,P＜0.05; 12h,t=3.086,P＜0.01; 18h,t=2.535,P＜0.05;24h,t=2.150,P＜0.05;36h,t =2.485,P ＜ 0.05),The average cuNGAL of AKI rats and non-AKI rats have statistical significance at 6h,18 h,and 24 h (6 h,t=3.013.P＜0.01; 18 h,t =4.804,P＜0.01; 24 h,t=2.682,P＜0.05).At 6 h,Uout can increase cuNGAL' s ability of predicting AKI' s occurrence in 24 hours (AUC increased from 0.839 to 0.900,P ＜ 0.05).Conclusions The intervention to the sepsis rats have influence on the secretion volume and secretion sequence of NGAL in rat urine.uNGAL and cuNGAL are good predictor of AKI occurrence in sepsis rats.
ABSTRACT
@#In the investigation of asymmetric catalytic hydrogenation reaction, (Z)-methyl-2-acetamidocinnamate is often used as a standard substrate to assess the chiral catalysts. However, its previous syntheses suffered from low yield, relying on column chromatography for isolation. Herein, (Z)-methyl-2-acetamidocinnamate was obtained with 68. 5% isolation yield via simple operations such as wash and extraction using dicyclohexylcarbodiimide(DCC)as dehydrant and 4-dimethylaminopyridine(DMAP)as catalyst in the last synthetic step.

ABSTRACT
Objectives To investigate the neuroprotective mechanism of vagus nerve stimulation ( VNS) by stimulating the vagus nerve in ischemic cerebral tissue in a rat model of transient focal cerebral ischemia. Methods Twenty-six adult male Sprague-Dawley ( SD ) rats were randomly divided into sham operation group (n=6),model group (n=10),and VNS-treated group (n=10) . The model of rat transient focal cerebral ischemia was induced by the intraluminal suture method. At 30 min after modeling,the right side neck VNS in the VNS-treated group was stimulated ( stimulus intensity 0. 5 mA, interval 0. 5 ms, frequency 20 Hz),once every 5 min within 1 h,and once for 30 s. The model group repeated the steps of the VNS-treated group,but did not stimulate. The sham operation group repeated the experimental steps,but it neither embolized the vessels nor stimulated nerves. The changes of cerebral blood flow were monitored with a laser Doppler flowmeter. The rats were sacrificed after 24 h. The expressions of interleukin 6(IL-6) and caspase-3 in brain tissue were determined by immunohistochemistry staining. The neuronal apoptosis was observed by the in situ end-labelling technique. Results ( 1 ) Compared with the sham operation group, the number of positive cells of IL-6,caspase-3,and the numbers of neuronal apoptosis in the model group were significantly increased (20. 7 ± 5. 0 cells/HP vs. 2. 3 ± 1. 0 cells/HP,44. 5 ± 9. 5 cells/HP vs. 0,30. 9 ± 9. 0 cells/HP vs.0).Thereweresignificantdifferences(P0. 05). Conclusion The neuroprotective mechanism of VNS for cerebral ischemia may be associated with the inhibition of neuronal apoptosis and decreasing inflammatory response. It may not be associated with the changes of cortical cerebral blood flow.
ABSTRACT
Objective To investigate the neuroprotective effect of vagus nerve stimulation ( VNS) on a model rat of focal cerebral ischemia. Methods A total of 42 adult male Sprague-Dawle ( SD) rats were randomly divided into a sham operation group (n=10),a model group (n=16),and a VNS-treated group ( n = 16 ) . Each group was randomly redivided into 2 subgroups:left VNS subgroup and right VNS subgroup. A model of focal cerebral ischemia (2 h) in rats was induced by the intraluminal suture method. At 30 minutes after modeling, the VNS-treated group received cervical VNS, the stimulation intensity was 0. 5 mA,the interval was 0. 5 ms,and the frequency was 20 Hz. Stimulation was once every 5 min within 1 h and each lasted for 30 s. The model group did not give any stimulation. Neither blood vessels were embolized nor were the nerves stimulated in the sham operation group. The changes of somatosensory evoked potentials ( SEP) on the lesion sides during operation were monitored. At 24 h after modeling,the neurobehavioral scores were performed. The rats were sacrificed,and their brain infarct volume was measured. Results (1) During the stimulation of left VNS in rats,the neurobehavioral scores of the sham operation group,model group and VNS-treated group were 0. 4 ± 0. 2,9. 5 ± 0. 4,6. 4 ± 0. 3,respectively;during the stimulation of right VNS in rats,the neurobehavioral scores of the 3 groups were 0. 6 ± 0. 2,9. 3 ± 0. 4,and 6. 9 ± 0. 4,respectively. There were significant differences between the scores of the model group and those of the other 2 groups (P0. 05). Conclusion No matter whether to stimulate the left or right vagus nerves, they both have neuroprotective effects on ischemic brain injury, and there was no significant difference on the action effects.

ABSTRACT
Objective To analyze the impact of medical insurance reimbursement mechanism on the income of urban community health centers run by various entities. Methods The data of the baseline survey of community health centers in 28 cities made in 2007 were called into play. These data were used to compare the percentage of the annual medical insurance income from outpatient clinics of three types of community health centers in their gross annual income and their annual outpatient clinic income. Results For 929 community health centers with income from medical insurance reimbursement, the average percentage of their annual income from outpatient clinic accounts for 24% of their gross annual income and 26. 09% of their annual outpatient income;In respect of the reimbursement rates of medical insurance at outpatient clinics, the highest come from those run by enterprises, secondly those by the government,and the least those run by social organizations or individuals. Conclusion The mechanism of medical insurance reimbursement has already affected the income of the third type of community health centers. It is recommended to raise the coverage rate of medical insurance of such type of centers and their reimbursement rates of medical insurance. This may further consolidate the policies of medical insurance reimbursement.
ABSTRACT
The risk factors of coronary artery disease, angiographic and procedural features are the main risk factors of restenosis after coronary artery stent implantation. In different combinations, these risk factors have different effects on coronary restenosis. The risk factors that the results of trials were more consistent include coronary lesion length, lesion vessel diameter <3 mm, ostial disease, total stent length, and number of stent. The same results of trials as stated above indicated that drug-eluting stent (sirolimus-eluting stent and paclitaxel-eluting stent), compared with bare-metal stent, significantly decreased the risk of restenosis. Compared these two drug-eluting stent, sirolimus-eluting stent was superior to paclitaxel-eluting stent on lowering the risk of restenosis. About other risk factors, e.g. age, sex, smoking, hypertension, the results of trials had inconsistent.

ABSTRACT
nephrectomy in Wistar rats were used to replicate the animal model of focal and segmental glomerular sclerosis.Then a group of 5/6 nephrectomized rats were given Benzaipril for 20 weeks , in order to evaluate the effects of Benazipril on degradation of extracellular matrix. The results showed that Benzipril not only reduced renal pathological changes, but also significantly decreased the type Ⅳ collagen and MMP 9 deposition and down regulated the mRNA expressions of MMP 9 and TIMP 1 in the remnant kidneys of the 5/6 nephrectomized rats. It suggested that Benzipril might ameliorate glomerulosclerosis through the mechanism of modulating extracellular matrix degradation in the remnant kidney tissue.
