Objective To investigate the effects of Benazepril on inflammatory cytokines in patients with primary hypertension and its efficacy analysis.Methods 72 patients with mild to moderate primary hypertension were randomly divided into benazepril group(37 cases)and control group(35 cases).The control group patients were given felodipine sustained release tablets Stag,1 times daily.Benazepril group were given benazepril tablets 10mg,1 times daily.Both groups were treated for 8 weeks.Changes in blood pressure and heart rate,plasma inflammatory cytokine levels and the adverse reactions were observed.Results After 8 weeks of treatment,the patients' blood pressures were significantly decreased (t =2.87,2.43,2.31,2.23,P ＜ 0.05 or P ＜ 0.01) than before in both groups.And the decrease in the benazepril group was more obvious than that in the control group (t =2.21,2.13,all P ＜ 0.05),while the patients' heart rates in the two groups showed no significant change (P ＞ 0.05) ; Patients' plasma IL-4 and IL-8 levels decreased significantly,plasma IL-10 levels increased significantly (t =2.99,2.87,3.21,2.13,2.19,2.23,all P＜0.05 or P＜0.01),and the magnitude of decrease or increase in the benazepril group were more obvious compared with the control group (t =2.21,2.13,2.34,all P ＜ 0.05).Conclusion Benazepril in the treatment of primary hypertension has good antihypertensive effect and security which can significantly reduce the plasma levels of proinflammatory cytokines IL-4 and IL-8 levels,improve the anti-inflammatory cytokine IL-10 levels,and has the role of suppressing the inflammatory response of the vessel wall.

Objective To investigate the effect of budesonide atomization on tracheal extubation in children.Methods A total of 85 patients with tracheal intubation in Tianjin Children's Hospital from May 2013 to September 2016 were selected in this study.Patients were randomly divided into budesonide group (n=44) and dexamethasone group (n=41).The budesonide group was given 1 mg of budesonide for inhalation 30 min before extubation,and 1 mg of budesonide inhalation immediately after extubation.Then every 8 hours for 0.5-1.0 mg budesonide inhalation for 4 days.The dexamethasone group was given dexamethasone 0.2-0.3 mg/kg intravenously 30 min before extubation,and dexamethasone 2.5-5.0 mg inhalation immediately after extubation.Then dexamethasone 2.5-5.0 mg inhalation was given every 8 hours for 4 days.The incidence of laryngeal edema (stridor,hoarseness),the time of extinction,the expression of hypoxia,reintubation rate within 24 hours and secondary infection rate after extubation were compared between the two groups.Results There were no significant differences in the mission success rate,the incidence of laryngeal edema,the time of extinction,the incidence of hypoxia and re-intubation rate between the two groups (P ＞ 0.05).Two patients were found secondary infection after extubation in dexamethasone group.Conclusion Both budesonide and dexamethasone show curative effects on the prevention and treatment of laryngeal edema after extubation.Budesonide atomization can replace systemic corticosteroids,thus reducing the adverse reactions of glucocorticoids.We recommend the use of budesonide in treating adverse events after extubation.

Aim To investigate the effect that catalpol intervenes macrophage polarization mediated by mouse mesangial cells(MMCs) stimulated by advanced glycation end products(AGEs).Methods RAW264.7 macrophages and MMCs were co-cultured in vitro and divided into model group(100 mg·L-1 AGEs), control group(100 mg·L-1 BSA), catalpol(0.1, 1.0, 10.0 μmol·L-1) group, and aminoguanidine(1.0 μmol·L-1) group which was set as positive control.After being incubated with catalpol for 1 h, MMCs were stimulated by AGEs for 23 h.The proliferation-inhibition rate of MMCs was measured by MTT assay.MCP-1 in supernatant liquid of MMCs was detected by ELISA method.The expression of iNOS, CD16/32, TNF-α, COX-2, CD206 and Arg-1 was detected by Western blot.Simultaneously, the percentage of iNOS and CD206 was also measured by flow cytometry.Results AGEs could increase the level of MCP-1 secreted by MMCs.The expression of iNOS, TNF-α, CD16/32 and COX-2 protein of macrophage was up-regulated after MMCs stimulated by AGEs, while the expression of CD206 and Arg-1 was down-regulated.After being intervened by catalpol, these effects could be reversed.All the changes were concentration-related.Conclusions Catalpol can inhibit macrophages M1-type polarization process and promote M2-type polarization, which may be mediated through MCP-1 secreted by MMCs after AGEs stimulation.Catalpol can ameliorate inflammation and relieve diabetic kidney injury.

Objective: To explore school counselors' attitude and decision-making towards dual relationship and confidentiality. Methods: Totally 123 school counselors (27 males and 96 females, aged 20 to 60 years old, 41 primary and secondary counselors, 82 college counselors) filled up of self-designed Questionnaire for School Psychological Consultants on Dual Relationship and Confidentiality Rules, and the related factors which could influence the school counselors' attitude and their decision-making in dual relationship and confidentiality in the counseling work. Results:Totally 71.5％ (n =88) school counselors chose not to accept other relationships with students after counseling, 14.6％ (n = 18) school counselors chose to accept other relationships with students after counseling. The school counselors who had not accepted supervisioneasier to answer as "accept other relationship may raise clients self-esteem or feelings" than those had got supervision (P <0.05). The school counselor believed that the confidentiality agreement should be breached of the top 3(suicide attention, drug use and bad gangs). Counselors easier to breach confidentiality agreements on situation of students had suicide plans than situation of students had plans to run away from home(P <0.001). Conclusion:This study shows that two factors, including supervision and differential clients "issue may have effect on school counselors" attitudes and decision-making towards dual relationship and confidentiality situation in their counseling practice.

Objective To compare the short-term clinical efficacies of Da Vinci robotic surgical systemassisted and laparoscopy-assisted radical gastrectomy for locally advanced gastric cancer (GC).Methods The retrospective cohort study was conducted.The clinicopathological data of 162 patients who underwent minimally invasive radical gastrectomy for locally advanced GC in the First Affiliated Hospital of Army Medical University between September 2016 and September 2017 were collected.Of 162 patients,65 undergoing Da Vinci robotic surgical system-assisted radical gastrectomy were allocated into the robotic group and 97 undergoing laparoscopyassisted radical gastrectomy were allocated into the laparoscopic group.According to Japanese gastric cancer treatment guidelines,patients with upper GC and with middle or lower GC underwent respectively total gastrectomy + D2 lymph node dissection and distal subtotal gastrectomy + D2 lymph node dissection,and then Billroth Ⅱ or Roux-en-Y digestive tract reconstruction.Observation indicators:(1) surgical and postoperative situations;(2) detection of lymph node;(3) follow-up and survival situations.Measurement data with normal distribution were represented as x±s,and comparisons between groups were analyzed using the t test.Comparisons of count data were done using the chi-square test.Ordinal data were analyzed by the nonparametric test.Results (1) Surgical and postoperative situations:all 162 patients underwent successful surgery,without conversion to laparoscopic or open surgery,and pathological resection margins were confirmed as R0.Volume of intraoperative blood loss,levels of amylase in peritoneal drainage fluid at day 1,2 and 3 postoperatively,levels of serum amylase fluid at day 1,2 and 3 postoperatively were respectively (123±39) mL,(557± 181) U/L,(357± 127) U/L,(183±86) U/L,(181±47)U/L,(123±29)U/L,(85±22)U/L in the robotic group and (142±40)mL,(793±284)U/L,(497±199)U/L,(279±157) U/L,(218±45) U/L,(162±37) U/L,(120±31) U/L in the laparoscopic group,with statistically significant differences between groups (t =-3.015,-2.817,-2.364,-2.132,-2.372,-3.338,-3.720,P＜0.05).Cases with distal subtotal gastrectomy + D2 lymph node dissection and with total gastrectomy + D2 lymph node dissection,cases with Billroth Ⅱ and Roux-en-Y of digestive tract reconstruction,time of distal subtotal gastrectomy + D2 lymph node dissection,time of total gastrectomy + D2 lymph node dissection,cases with anastomotic leakage,pulmonary infection,wound infection or liquefaction and delayed gastric emptying,cases in grading Ⅱ,Ⅲ,Ⅳ and Ⅴ of postoperative complications,time of postoperative drainage-tube removal and duration of postoperative hospital stay were respectively 47,18,40,25,(222±37) minutes,(274±43) minutes,1,1,1,1,2,1,0,0,(6.5-± 1.5) days,(10.0±4.0) days in the robotic group and 74,23,69,28,(213±40) minutes,(262±39)minutes,2,4,1,0,4,1,0,1,(6.9±1.7)days,(10.0±5.0)days in the laparoscopic group,with no statistically significant difference between groups (x2=0.326,1.628,t =1.272,0.960,x2=2.501,Z=-1.342,t=-1.142,-0.115,P＞0.05).One and 1 patients in the robotic and laparoscopic groups who were complicated with esophagus-jejunum anastomotic leakage after total gastrectomy + Roux-en-Y anastomosis were cured by nutrition support therapy using feeding tube placement under gastroscopy,and 1 patient in the laparoscopic group who were complicated with gastrojejunal anastomosis leakage after distal subtotal gastrectomy +Billroth Ⅱ anastomosis received the second surgical exploration and jejunal feeding tube placement.Patients with pulmonary infection,wound infection or liquefaction and delayed gastric emptying were cured by conservative treatment.Levels of amylase in peritoneal drainage fluid and serum amylase fluid at day 1,2 and 3 postoperatively were not higher than 3 times of upper limit of normal,without treatment interventions.(2) Detection of lymph node:overall number of lymph nodes detected in the robotic and laparoscopic groups were respectively 36.82±13.41 and 35.21 ± 11.52,with no statistically significant difference between groups (t =0.786,P＞ 0.05).Results of further analysis showed that numbers of lymph node dissected in the 2nd station and upper region of pancreas in patients undergoing distal subtotal gastrectomy + D2 lymph node dissection were respectively 6.04±3.98,13.51±6.53 in the robotic group and 4.45±3.12,11.40±5.30 in the laparoscopic group,with statistically significant differences between groups (t=2.461,1.986,P＜0.05).Numbers of lymph node dissected in No 7 and 8 groups and upper region of pancreas in patients undergoing total gastrectomy + D2 lymph node dissection were respectively 5.44±2.63,2.92±1.87,10.81±4.78 in the robotic group and 3.11±1.82,1.62±1.33,7.76±3.34 in the laparoscopic group,with statistically significant differences between groups (t =3.340,2.689,2.522,P＜0.05).(3) Follow-up and survival situations:of 162 patients,148 were followed up for 2-14 months,with a median time of 8 months.During the follow-up,patients in the 2 groups had tumor-free survival.Conclusions Da Vinci robotic surgical system-assisted radical gastrectomy is safe and feasible.Compared with laparoscopy-assisted radical gastrectomy for locally advanced GC,it has advantages of clear vision of the local anatomy,less intraoperative bleeding,more numbers of lymph nodes dissected in the upper region of pancreas and lighter pancreatic injure,meanwhile,it has also certain operating advantages around the great vessels and in the deep and narrow spaces.

Objective:To explore the consistency of peripheral whole blood and venous serum procalcitonin (PCT) levels, and the value of peripheral whole blood PCT in evaluating pediatric bacterial infection.Methods:This multicenter cross-sectional parallel control study was conducted in 11 children′s hospital. All the 1 898 patients older than 28 days admitted to these hospitals from March 2018 to February 2019 had their peripheral whole blood and venous serum PCT detected simultaneously with unified equipment, reagent and method. According to the venous serum PCT level, the patients were stratified to subgroups. Analysis of variance and chi-square test were used to compare the demographic characteristics among groups. And the correlation between the peripheral blood and venous serum PCT level was investigated by quantitative Pearson correlation analysis.The PCT resultes were also converted into ranked data to further test the consistency between the two sampling methods by Spearman′s rank correlation test. Furthermore, the ranked data were converted into binary data to evaluate the consistency and investigate the best cut-off of peripheral blood PCT level in predicting bacterial infection.Results:A total of 1 898 valid samples were included (1 098 males, 800 females),age 27.4(12.2,56.7) months. There was a good correlation between PCT values of peripheral whole blood and venous serum ( r=0.97 , P<0.01). The linear regression equation was PCT?venous serum=0.135+0.929×PCT peripheral whole blood. However, when stratified to 5 levels, PCT results showed diverse and unsatisfied consistency between the two sampling methods ( r=0.51-0.92, all P<0.01). But after PCT was converted to ordinal categorical variables, the stratified analysis showed that the coincidence rate of the measured values by the two sampling methods in each boundary area was 84.9%-97.1%. The dichotomous variables also showed a good consistency (coincidence rate 96.8%-99.3%, Youden index 0.82-0.89). According to the severity of disease, the serum PCT value was classified into 4 intervals（<0.5、0.5-<2.0、2.0-<10.0、≥10.0 μg/L）, and the peripheral blood PCT value also showed a good predictive value (AUC value was 0.991 2-0.997 9). The optimal cut points of peripheral whole blood PCT value 0.5、1.0、2.0、10.0 μg/L corresponding to venous serum PCT values were 0.395, 0.595, 1.175 and 3.545 μg/L, respectively. Conclusions:There is a good correlation between peripheral whole blood PCT value and the venous serum PCT value, which means that the peripheral whole blood PCT could facilitate the identification of infection and clinical severity. Besides, the sampling of peripheral whole blood is simple and easy to repeat.
