To observe the effect of PCEA on the serum endotheline and the renal function after operation in kidney transplantation patients. Forty patients with chronic renal failure were randomly divided into two groups: group P( n =20) and group N ( n =20) .Venous blood samples were drawn before anesthesia at the end of operation and 24, 48, 72h after operation. Mean arterial pressure (MAP), serum endothelin,creatinine, urea nitrogen, uric acid were measured with radioimmunoassay. The results showed that the MAP, serum endothelin, creatinine, urea nitrogen and uric acid were decreased significantly at 24h after operation.All of them reached the nadir at 72h after operation. But those of group N were significantly higher than group P ( P

Objective:Coherence analysis of the EEG is used to study the synchrony or coupling between cortical areas underlying the electrodes. However,the effects of intravenous anesthetics on EEG coherence have not been defined. Method: Forty patients were administered with intravenous thiopental (5mg/kg),propofol (2.5mg/kg ), ketamine(4mg/kg)or fentanyl(10?g/kg). The changes of coherences in total and in a given frequency band of the EEG(?.?.?.?) were measured with an AXON Systems Sentinel-4 Neurological monitor between two pair electrodes(Cz-F_7 vs Cz-F_8 and Cz-A_1 vs Cz-F_2). Result: The anesthetics had significantly different effects on the coherence by either increase or decrease. The variability of the coherences had no regular pattern,and no relationship to excitement or depression of the anesthetics and to potency of them. Conclusion:Each anesthetic above selectively depresses and excites generators of the EEG in quite different ways.

Objective To investigate the effect of small dose of dexmedetornidine on venous continuous infusion combined with oxycodone or fentanyl during brachial plexus blockade.Methods Sixty thyroid patients (ASA Ⅰ or Ⅱ) undergone brachial plexus anesthesia for cutting or cutting thyroid tumor patients were randomly and double-blindly into three groups (n =20 in each group).Group A:single brachial plexus anesthesia;group B:dexmedetornidine combined with fentanyl;group C:dexmedetornidine combined with oxycodone.Blood pressure (Bp),heart rate (HR),the determination of plasma norepinephrine (NE),cortisol (Cor),the concentration of blood glucose (Glu),VAS,Ramsay calm score,local anesthetics dosage and side effect formation rate at the beginning operation (To),skin incision (T1),separation of the glands (T2),gland excision (T3),and the end of the surgery (T4) were recorded.Results Compared to group A,the mean arterial pressure (MAP),HR,NE,Cor,and Glu were much lower at each time point (P ＜ 0.05) in groups B and C;Ramsay calm score and VAS score were significantly better at each time point (P ＜ 0.05);the incidence of chills and lidocaine additional quantity were significantly lower (P ＜0.01).However,compared to groups A and C,choking cough response rates were much higher in group B (P ＜ 0.01).Conclusions Small dose of dexmedetornidine on venous continuous infusion combined with oxycodone during brachial plexus blockade for thyroid patients both can eliminate the preoperative patients nervous anxiety,and effectively restrain perioperative stress response,maintain hemodynamics stable,implementation of intraoperative awaken to reduce complications.It is the new choice of anesthetic adjuvant.

Acute ST-segment elevation myocardial infarction with multivessel disease is one of the high-risk types of coronary heart disease.Early opening of infarct-related artery and reperfusion of myocardium could significantly reduce the mortality in acute phase.However,the presence of non-culprit lesions in non-infarct-related arteries is still at risk and has an important impact on the long-term prognosis of patients.It remains controversial on how to precisely evaluate the clinical significance and revascularization value of non-culprit lesions.This article aims to review the research status and progress of guidance strategies of non-culprit lesion revascularization in patients with ST-segment elevation myocardial infarction and multivessel disease.

Background::Dermatophagoides pteronyssinus is a common allergen causing allergic diseases in China. The aim of this study was to evaluate the efficacy and safety of D. pteronyssinus extracts produced by Peking Union Medical College Hospital (PUMCH) for the skin prick test (SPT) in the diagnosis of D. pteronyssinus allergy. Methods::A total of 910 subjects with allergic diseases were prescribed D. pteronyssinus SPT and specific sIgE (sIgE) test among the Outpatients of Department of Allergy, PUMCH from August 10, 2015 to August 30, 2017. Receiver operating characteristic curve (ROC) analysis was performed according to the results of D. pteronyssinus-sIgE detection. The accuracy of D. pteronyssinus extracts used for SPT in the diagnosis of D. pteronyssinus allergy was evaluated under different cutoff values. Adverse events after SPT were recorded to evaluate safety. Results::There were 796 and 618 subjects in the full analysis set (FAS) and the per protocol set (PPS), respectively. The areas under the curve of FAS and PPS were 0.871 and 0.873, respectively. According to the ROC of PPS, the optimal and 95% specificity diagnostic cutoff values of D. pteronyssinus SPT mean wheal diameter were 3.25 and 3.75 mm, respectively. No adverse events occurred. Conclusion::The extracts of D. pteronyssinus for SPT were simple, highly accurate, and safe and should be considered for recommendation in the clinical diagnosis of D. pteronyssinus allergy.

Objective:The preseason prophylactic treatment of seasonal allergic rhinitis (AR) caused by pollens could alleviate AR symptoms during the pollen season. This study aimed to evaluate the effect of prophylaxis usage of suplatast tosilate on the life quality of AR patients in the pollen season, and investigate the potential mechanism of action through transcriptomic analysis.Methods:This is a randomized controlled study. AR patients allergic to weed pollens were recruited from Allergy Clinic of Peking Union Medical College Hospital from January 2020 to June 2020, and divided into prophylactic group who started to take suplatast tosilate as prophylaxis 2 weeks before the spread of weed pollens[n=10, 4 men and 6 women with age range of (34±6) years old] and control group who did not use any prophylactic treatment[n=24, 12 men and 12 women with age range of (33±9) years old]. The differences of age ( t=0.381, P=0.706) and gender ( χ2=0.595, P=0.715) distribution between the patients of two groups were not statistically significant. All the subjects filled in the rhinoconjunctivitis quality of life questionnaire (RQLQ) while onset of AR symptoms, and peripheral blood was drawn for transcriptomic analysis 1 month before and during the pollen season. Differences between groups were statistically analyzed through chi-square test and t test. Results:There was no significant difference in visual analogue scale of rhinitis symptom in the last pollen season between prophylactic group and control group[ 8.0 (6.4, 9.3) vs 7.3 (6.1, 8.0), Z=1.180, P=0.254]. The RQLQ score of prophylactic group was superior to that of control group in the weed pollen season (2.9±0.9 vs 3.7±0.9, t=-2.438, P=0.026). 210 differentially expressed genes of fold change ≥2 were identified, with 147 genes upregulated and 63 genes downregulated in the prophylactic group compared to the control group. Gene Ontology annotation showed that IL-12 and IL-23 related pathways were downregulated in prophylactic group ( P=0.006 48). Polymerase Chain Reaction (PCR) verification of differentially expressed genes indicated that the relative expression level of HLA-G in prophylactic group was significantly lower than that in control group (0.23±0.19 vs 1.00±0.49, t=4.016, P=0.006). Conclusion:The prophylactic treatment of suplatast tosilate showed some benefit to the life quality of seasonal AR patients during the pollen season, and the potential mechanism might be related with the downregulation of IL-12 and IL-23 pathways and decreased expression of HLA-G.
