Objective to compare the LMA and intubation in elderly patients with coronary heart disease hemedynamics,respiratory function and the impact of stress hormones.Methods 32 cases of elderly patients with coronary heart disease ASA II level under general anesthesia in the implementation of gastrointestinal surgery,were randomly divided into LMA group and endotracheal intubation group.Before the induction of anesthesia (T0),insert the LMA/endotracbeal tube before(T1),insert the LMA/tracheal tube immediately after(T2),insert the LMA/endotracbeal tube after 5 min(T3) ,10 min(T4),15 min(T5) and the skin incision,(T6) ,immediately after extubation (T7) record SBP,DBP,HR.Application BICORE monitor respiratory function 16 indicators,select T0,T3,T4,T5,T7 record at the suction tidal volume (,VTI),breath tidal volume (VTE),minute ventilation (VE),Inspiratory peak velocity(PIFR),peak expiratory flow rate (PEFR) ,peak inspiratory pressure(PIP) and the average airway resistance (RAWM).Patients in each group T0,T1,T2,T6,T7 at the application of high performance Iiqnid chromatography analysis of plasma epinephrine(AE),norepinephrine(NE),dopamine (DA) level.Results intubation group T2 at the SBP,DBP,HR significantly higher than the LMA group (P＜0.05) ;,VTI,VTE,VE,PIFR,PEFR,PIP and RAWM group there was no significant difference,AE,NE,DA in T2,T7,were significantly higher than the LMA group (P＜0.05).Conclusion Laryngeal Mask Airway general anesthesia for elderly patients with coronary heart disease is better than intubation,easy to maintain stable bemedynamics,the stress response minor,after the restoration of a smooth general anesthesia.

Objective To evaluate the effect of age on pharmacodynamics of eisatracurium target-controlled infusion(TCI). Methods Forty patients under N_2O-O_2-propofol-fentanyl anesthesia were divided into groups of Ⅰ and Ⅱ with 20 cases each. Under TOF stimulation monitoring, eisatracurium 0. 15 mg/kg was injected and tracheal intubation was performed when TOFr being zero. and the intubation conditions were evaluated. When T1 restored to 50% cisatracurium TCI started to keep TOFr less than 10%. The recovery times of neuromuscular blockade were recorded after stopping infusion. The amount of cisatracurium consumption was calculated. Results Intubation conditions the onset time and recovery index were not significantly different between two groups. The nonresponse period, duration of action, and recovery time were longer in group Ⅰ than those in group B. Cisatracurium consumption was more in group Ⅰ than that in group Ⅱ (P<0.05). Conclusion By TCI,cisatracurium dosage needed for keeping TOFr less than 10% is less,but the recovery process is still longer in the elderly than those in the younger.

Objective To discuss the nursing points for patients with malignant obstructive jaundice who are receiving biliary stenting combined with linear 125I seeds strand implantation. Methods A total of 41 patients with malignant obstructive jaundice were enrolled in this study. Biliary stenting combined with linear 125I seeds strand implantation was performed in all the 41 patients. Sufficient preoperative preparation and psychological intervention were carefully implemented. During the operation, active cooperation with the surgical procedures and close observation of patient’s vital signs as well as adverse reactions such as nausea and vomiting were strictly carried out. After the treatment the management of PTCD drainage tube, the protection of radiation and the early detection of complications were further emphasized. Results The technical success rate of biliary stenting together with linear 125I seeds strand implantation was 100%. The serum total bilirubin levels, determined at one week, one and 3 months after the treatment, were significantly decreased when compared with the preoperative data. Clinically, the jaundice basically subsided. Bile-cardiac reflex occurred in one case and displacement of PTCD drainage tube in 2 cases. Twelve patients developed chills and fever after operation. Acute renal insufficiency occurred in one patient, which was relieved after effective management. The median survival time was 10.9 months. Conclusion Careful and comprehensive preoperative preparation can ensure a successful operation. Intraoperative close observation of patient’s condition and skilled cooperation with the operator, and high quality postoperative nursing measures and close observation for early signs of complications are essential nursing points to ensure that the patients can safely get over the rehabilitation period.

Background The circulating endothelial progenitor cells (EPCs)play an important role in postnatal vasculogenesis and restoration of endothelial injury.Previous investigation illustrated that a reduced ocular blood flow and vascular dysfunction caused by endothelial dysfunction plays a role in the pathogenesis of glaucoma.However,endothelial system accommodation is accomplished with the circulating EPCs.Objective The present trail was to investigate EPCs change in patients with primary acute angle-closure glaucoma (PACG)and explore the role of EPCs in the pathogenesis of PACG. MethodsA prospective cohort study was designed.Thirty patients with PACG were enrolled in Tianjin Medical University General Hospital as PACG group,and 20 normal subjects served as control group.Periphery bloodsamples were obtained fromall the patients and thenstained with saturating concentrations of monoclonal antibodies,FITC-conjugated anti-CD34 and CD133 mAb.EPCs identified by CD34,CD133 were enumerated by flow cytometry,and the correlation between EPCs change and its relative factors was analyzed.Informed consent was obtained from each subject before any medical procedure. Results No significant differences were found in age,gender,vascular-related risk factor,blood biochemical indicators between PACG group and normal contol group(P＞0.05 ),but a higher intraocular pressure( IOP)was displayed in PACG group compared with normal control group ( P =0.00 ).The numbers of EPCs were ( 48 ± 22 ) cells/ml in PACG group and ( 65 ± 20 )cells/ml in normal control group with a significant difference between them (P=0.004).In PACG group,the numbers of EPCs were(60± 19 )cells/ml and (34 ±7 )cells/ml respeetively in phase 1 and phase 3 of optical nerve damage (Z=-3.015,P=0.002 ).There was a negative correlation between EPCs numbers and baseline IOP within a certain range( r=-0.835,P＜0.05 ).However,no obvious correlations were seen between EPCs numbers and blood lipid Level,blood glucose level or glaucoma course ( r =0.343,P =0.227 ; r =-0.203,P =0.419 ; r =0.198,P =0.610 ).The EPCs numbers in PACG patients with cardiovascular disease were(56±22)cells/ml and that of without PACG were (35± 15 ) cells/ml( P =0.005 ). ConclusionsThe numbers of EPCs decrease in PACG patient.These results imply that EPCs might play role during the restore of the optical nerve damage in PACG eye.

Objective To investigate the clinicopathologic features and the expression of p53,PCNA and Bcl-2in tricholemmal carcinoma.Methods Skin lesions were studied with HE staining and immunohis-tochemical markers for p53,PCNA and Bcl-2(S-P method)in22cases of skin tricholemmal carcinoma.Both morphological manifestations and immunohistochemical expression were observed.Results There were15fe-male and7male cases of tricholemmal carcinoma with the ages of40-79y,including16cases whose scalp were involved.Positive staining of p53,PCNA and Bcl-2was found in72%,100%and63%of patients,re-spectively.The positive cells of p53were diffusely distributed.PCNA-positive cells were increased along with the degree of differentiation.Significant differences of Bcl-2expression were found among the various degrees of differentiation(P

BackgroundLaser peripheral iridotomy(LPI) can break the pupillary block,and is an effective method of treating acute primary angle closure (APAC).However,a part of APAC eyes may gradually develop a formation and extension of peripheral anterior synechia(PAS) and increased intraocular pressure(IOP) after LPI.ObjectiveTo investigate the relationship between appositional angle closure and darkroom provocative test(DRPT) in the fellow eyes with APAC after LPI.Methods Fellow eyes of APAC without PAS after LPI were studied.Ultrasounic biomicroscopy(UBM) were performed in darkness to observe whether appositional angle closure occurred and compare the relationship between the quadrants with appositional angle closure and the results of DRPT.Results Fifty-four patients were included in the study.Appositional angle closure was observed in at least one quadrant in 20(37.0％ ) of the 54 fellow eyes with APAC after LPI.Fifty-one patients were given DRPT and positive result in 9 patients( 17.6％ ).According to the quadrants with appositional angle closure,there were 5 patients with DRPT positive results in 46 patients with appositional angle closure 0 to 2 quadrants,and 4 patients with DRPT positive results in 5 patients with appositional angle closure 3 to 4 quadrants ( P =0.003 ).Bivariate correlation analysis indicated a positive correlation between the value of the increased IOP in DRPT and the number of quadrants with appositional angle closure in darkness( r =0.397,P =0.004).ConclusionsA certain proportional fellow eyes of APAC appeared appositional angle closure in darkness and DRPT positive result after LPI.The more the quadrants of appositional angle closure after LPI,the greater the likelihood of a positive DRPT.It suggests that the APAC fellow eyes and attack eyes with the same anatomical configuration still have the possibility of angle closure after LPI,and need follow-up and treatment for a long time.

Objective To investigate the resting-state functional connectivity of the two hemispheres between multiple system atrophy (Parkinsonian type,MSA-P) and Parkinson's disease (PD).Methods A total of 25 MSA-P,29 PD patients and 29 well-matched healthy controls recruited in the Nanjing Brain Hospital Affiliated to Nanjing Medical University from June 2013 to December 2015 were scanned with resting-state functional magnetic resonance imaging for voxel mirrored homotopic correlation (VMHC) analysis.The Mini Mental State Examination,Montreal Cognitive Assessment,Frontal Assessment Battery and Unified Parkinson's Disease Rating Scale-Ⅲ (UPDRS-Ⅲ) were used to assess the clinical symptom.Then the relationship between the change of VMHC values and severity of clinical symptoms was investigated.Results Compared with healthy controls,MSA-P and PD patients both showed decreased VMHC in bilateral cerebellum posterior lobe,precuneus gyrus,middle temporal gyrus,and postcentral gyrus.Compared with PD or healthy controls,MSA-P patients exhibited lower VMHC in bilateral putamen.Significant negative correlation between VMHC values of putamen and UPDRS-Ⅲ scores was found in MSAP patients (r =-0.607,P =0.001).Conclusion These functional changes suggest that the abnormal interhemispheric synchrony probably plays an important role in pathophysiology of both MSA-P and PD,and abnormal VMHC values in putamen of MSA-P may be helpful in differentiating MSA-P from PD.
