To screen potential human soluble epoxide hydrolase (hsEH) inhibitors, a high-throughput screening model in 384-well microplate with total volume of 50 microL was established. Recombinant hsEH was cloned and expressed in E. coli. and its specific substrate PHOME was synthesized. The HTS model was based on fluorescence analysis with enhanced sensitivity and specificity (Z' = 0.65). A total of 47 360 samples (including 25 040 compounds and 22 320 natural products) were screened, of which 950 samples with inhibition greater than 80% were selected for further rescreening. Finally, two compounds with high inhibitory activity were identified, whose IC50 value were 8.56 and 4.31 micromol x L(-1), separately. The results indicated that the method was stable, sensitive, reproducible and also suitable for high-throughput screening.

Objective To investigate the effect of preoperative prophylactic parenteral nutrition on prognosis of advanced gastric cancer.Methods A total of 159 patients with advanced gastric cancer in our hospital were collected,and randomly divided into experimental group and control group.80 cases in experimental group were treated with prophylactic parenteral nutrition,and 79 cases in control group were treated with traditional nutrition.The partial indexes of liver function,complications and mortality rate were compared between the two groups before and after surgery.Results The levels of aspartate aminotransferase (AST),alanine aminotransferase (ALT),total bilirubin (TBIL) and direct bilirubin (DBIL) were much lower in experimental group than in control group at 8 days after surgery (t=6.542,6.460,5.634,5.275,all P＜0.001).The levels of ALB and PAB were much higher in experimental group than in control group at 2 and 8 days after surgery (t=12.580,12.471,6.757,12.821,all P＜0.001).The incidence of complications and mortality rate were much lower in experimental group than in control group (x2 =23.409,4.818,P＜0.001 or 0.05).Conclusions Preoperative prophylactic parenteral nutrition can speed up the recovery of liver function and reduce the complications and mortality rate after surgery in patients with advanced gastric cancer.

Objective To compare the scores from the simpliifed COMFORT scale with those from the bispectral index (BIS) and analyze the variation among different evaluators in children in an intensive care unit, and to investigate the reliability;validity of simpliifed COMFORT scale. Methods Twenty children between 3 and 16 years of ages on mechanical ventilation and sedation were simultaneously classiifed based on the BIS and the simpliifed COMFORT scale evaluated by 4 independent evalua-tors. The Kappa test was performed and the correlation between the two methods (Pearson correlation) was tested. Results In to-tal, 70 observations were performed on 20 patients. Based on the Kappa coefifcient, the agreement among evaluators ranged from 0.62 to 0.77 (P<0.001). There was a correlation between the BIS and the simpliifed COMFORT scale (r=0.53-0.61,P<0.01). Conclusions Due to the strong consistency between the independent evaluators and the correlation between the two methods, the reliability and validity of simpliifed COMFORT scale are preferable and simpliifed COMFORT scale is useful in classifying the level of sedation in children on mechanical ventilation.

Objective To explore the value of wound blush in predicting patients' ulcer healing whom with critical limb ischemia after revascularization.Methods Retrospectively analyze the clinical data of 173 cases of critical limb ischemia with ischemic ulcers under thetreatment of endovascular therapy followed the concept of angiosome.According to the condition of wound blush after endovascular therapy,by compared the difference of limb salvage rate and ulcer healing time,and try to analyze the value of wound blush in predicting ulcer healing in patients.Results Included in the study with a total of 173 cases (173 limbs),group wound blush(+) 109 patients,group wound blush (-) 64 cases,the age,proportion of male patients,smoking history,diabetes,coronary heart disease,chronic renal insufficiency,pre and post operative ankle brachial index,were no statistical difference between the two groups.The ulcer healing time of group wound blush (+) was significantly shorter than that of group wound blush(-) (P ＜ 0.05).The rate of ulcer healing in group wound blush(+) was significantly higher than that in group wound blush(-) (P ＜ 0.05).In group wound blush(+),the cumulative rate of limb salvage was statisticallyhigher than group wound blush (-) (P ＜ 0.05).By logistic regression analysis,wound blush(-) (OR =4.5,P ＜ 0.05),IRc revascularization (OR =2.6,P ＜ 0.05) were independent risk factors of ulcer healing.Conclusions The resoult of wound blush(+) shows a good distal perfusion of foot.It can be used as a predictive factor for critical limb ischemia ischemic ulcer healing,and wound blush (-) was an independent risk factor for ulcer nonhealing.

Objective To evaluate the correlations of pro-angiogenic miRNAs with risk and severity in patients with coronary artery disease (CAD). Methods After angiographic documentation, 10 patients with CAD and 10 healthy controls (HCs) were enrolled for screening the differently expressed microRNAs (DEMs) (exploration stage). Blood samples of 142 patients with CAD and 140 age- and gender-matched HCs with the same eligibility were collected (validation stage). And the plasma levels of DEMs were measured by real-time qPCR. Results In the exploration stage, miR-19a, miR-92a, miR-126, miR-130a, miR-210, miR-296, and miR-378 expression levels were higher, but miR-221 expression was lower in patients with CAD than in HCs. In the validation stage, plasma expression levels of miR-126, miR-130a, miR-210, and miR-378 were decreased in patients with CAD. Multivariate logistic regression revealed that miR-19a, miR-126, miR-130a, miR-210, and miR-378 were independent protective factors for CAD. Receiver operating characteristic (ROC) analysis displayed that testing of a combination of miR-19a, miR-126, miR-130a, miR-210, and miR-378 was of good value in predicting the risk of CAD, with an AUC of 0. 768. Additionally, miR-126 and miR-210 were negatively associated with Gensini scores. Conclusion miR-126, miR-130a, miR-210, and miR-378 could serve as promising biomarkers for predicting the risk and severity of CAD.

Objective To evaluate the efficacy and safety of short-term deep sedation strategy in patients with spontaneous intracerebral hemorrhage (ICH) after surgery. Methods A perspective, randomized, parallel-group study was conducted. Adult patients with spontaneous ICH and undergoing craniotomy admitted to Daxing Teaching Hospital of Capital Medical University from December 2015 to November 2016 were enrolled. The patients who received surgery were randomly divided into a short-term deep sedation and a slight and middle sedation group. Sufentanil was used as an analgesic drug in all patients and midazolam was used as a sedative after the operation. The patients in the slight and middle sedation group received midazolam 0.05-0.10 mg/kg with a goal of mild sedation [Richmond agitation and sedation scale (RASS) score of -2-1]. The patients in the short-term deep sedation group received midazolam 0.1-0.2 mg/kg with a goal of deep sedation (RASS score of -4 to -3) and a duration of no more than 12 hours. Postoperative sedation, blood pressure changes, laboratory indexes, residual hematoma and clinical outcomes were recorded in two groups. Results During the study, a total of 183 patients with spontaneous ICH were collected, excluding who was older than 65 years, with shock, and with preoperative Glasgow coma score (GCS) of 3. 106 patients were enrolled in this study, and 53 patients were assigned to the short-term deep sedation group and slight and middle sedation group, respectively. In the slight and middle sedation group, 4 patients received reoperation because of repeated hemorrhage and no patient operated repeatedly in the short-term deep sedation group, and there was a significant difference between the two groups (χ2= 4.000, P = 0.045). The number of patients undergoing tracheotomy in the short-term deep sedation group was significantly lower than that in the slight and middle sedation group (9 cases vs. 21 cases,P < 0.05). RASS score within 12 hours after operation of the patients in the short-term deep sedation group was lower than that in slight and middle sedation group [-4 (-4, -2) vs. -2 (-3, -1) at 4 hours, -4 (-4, -2) vs. -1 (-2, 0) at 8 hours,-3 (-4, -2) vs. 0 (-2, 1) at 12 hours, all P < 0.01], sudden restlessness was significantly reduced [times: 1 (0, 1) vs. 3 (2, 3), P < 0.01], and postoperative sedation duration was significantly prolonged [hours: 14.0 (8.3, 20.8) vs. 8.9 (3.4, 15.3), P < 0.05]. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) within 12 hours after operation in the short-term deep sedation group were significantly lower than those of the slight and middle sedation group [SBP (mmHg, 1 mmHg = 0.133 kPa): 136.8±30.5 vs. 149.1±33.5, DBP (mmHg): 85.0 (70.8, 102.3) vs. 89.0 (69.2, 116.7), both P < 0.05]. There were no significant differences in the arterial blood gas, routine blood test or coagulation function between the two groups at 24 hours after operation. The volume of residual hematoma at 2, 7 and 14 days after operation in the short-term deep sedation group was significantly decreased as compared with slight and middle sedation group (mL: 16.4±15.6 vs. 38.2±22.2 at 2 days, 9.6±8.7 vs. 20.6±18.6 at 7 days, 1.2±1.0 vs. 4.4±3.6 at 14 days, all P < 0.05), number of deaths in 3 months were significantly less (5 cases vs. 13 cases), and the patients with favorable prognosis were increased significantly (39 cases vs. 12 cases, both P < 0.05). Conclusion The study results showed that short-term deep sedation strategy after surgery can reduce the incidence of adverse events and improve the prognosis of patients with spontaneous ICH, so it is safe and effective.

Objective:To explore the influence of online and offline family therapy based on the Satir model on emotions of adolescents with depressive disorder and their parents in remote areas.Methods:A total of 98 cases adolescents with depressive disorder treated in the psychosomatic medicine of the Second Affiliated Hospital of Nanchang University from January 2021 to June 2021 and their parents were selected as the objects. The adolescents with depressive disorder and their parents were randomly divided into the control group (49 parents and 49 adolescents) and the observation group (49 parents and 49 adolescents). The control group received the medical treatment (sertraline 100 mg/d) and the routine health education, while the observation group received the online and offline Satir family therapy on the basis of the intervention of the control group. Generalized anxiety disorder-7 (GAD-7) and patient health questionnaire-9 (PHQ-9) were used to investigate the negative emotions of the parents of the two groups before and 12 weeks after the intervention. The screen for child anxiety related emotional disorders (SCARED) and depression self-rating scale for childhood (DSRS) were used to investigate the negative emotions of the adolescents before and 12 weeks after the intervention.The SPSS 20.0 software was used for statistical analysis. t test was used to compare the SCARED scale score and DSRS score changes of the adolescents in the two groups, and χ 2 test was used to compare the proportional changes of parents' anxiety and depression. Results:The scores of SCARED (51.55±12.69 vs 36.82±7.69, t=15.839) and DSRS (25.08±4.81 vs 16.88±2.16, t=13.047) of adolescents in the control group were significantly different before and after the intervention (both P<0.05). The scores of SCARED (51.16±15.84 vs 31.31±7.72, t=14.385) and DSRS (24.12±4.81 vs 14.08±2.03, t=14.723) of adolescents in the observation group were significantly different before and after the intervention (both P<0.05). After the intervention, the scores of SCARED and DSRS in the observation group were lower than those in the control group ( t=3.540, 6.609, both P<0.05). Before intervention, there was no significant difference in the proportion of anxiety and depression between the parents of the two groups (χ 2=1.837, 3.547, both P>0.05). After 12 weeks of intervention, there was a statistically significant difference in the proportion of anxiety and depression between the two groups, which were lower in the observation group than those in the control group (χ 2=5.995, 4.009, both P<0.05). Conclusion:Online + offline family therapy based on the Satir model can not only effectively reduce anxiety and depression of adolescents, but also effectively reduce anxiety and depression of their parents.It is especially suitable for outpatient management of children with depressive disorder in remote areas.

Objective:To analyze the clinical efficacy and safety of endoluminal treatment of complex renal artery aneurysm (RAA).Methods:The clinical data and follow-up results of 19 patients with complex RAA admitted to Renji Hospital, Shanghai Jiaotong University School of Medicine from November 2014 to September 2021 were retrospectively analyzed. Two patients were treated with simple spring coil embolization into the aneurysmal artery, 14 patients were treated with simple spring coil embolization of the aneurysmal cavity, and 3 patients were treated with stent-assisted + spring coil embolization technique. Based on the location of the aneurysm, RAA were classified into type Ⅰ, Ⅱ, and Ⅲ. 7 patients with type Ⅰ, 10 patients with type Ⅱ, and 2 patients with type Ⅲ were studied. Variance analysis was used to compare the differences in glomerular filtration rate(GFR) of the affected side when the tumor was located at different locations, and Pearson was used to analyze the correlation between the number of coils implanted and the size of the tumor and GFR.Results:Ten of the 19 patients who were underwent successful endoluminal intervention. The average size of the patients′ aneurysms was (20.89±6.65) mm, and the average number of spring coils implanted was 8.22±3.08. The preoperative and postoperative serum creatinine were in the normal range, and no RAA tumor enlargement or recurrence was found during the follow-up period. The postoperative GFR was abnormal in patients with type Ⅰ, type Ⅱ, and type Ⅲ renal aneurysms, and the mean GFR value differed among the three types of patients( P=0.003). There was a negative correlation between the postoperative GFR values of the affected kidney and the number of spring coils implanted ( P=0.047), and no significant relationship between GFR and aneurysm size. Conclusion:The endovascular technique is an effective and safe means of treating complex RAA.
