Objective To show epidemiological characteristics of adult emergency patients and to provide data support for grading clinics.Methods Adult emergency patients (older than 14 years) from 50 hospitals in Tianjin were included.Name,gender and age of patients,as well as visiting time/department,chief complaint,severity of the disease,prognosis were considered to cross-sectional survey from 8:00,30 Aug 2016 to8:00,31 Aug 2016.Chi-squared test,Fisher's exact test,or t test was used to statistical analysis as appropriate.Results Of 6 569 patients,most originated from medical (n =3 964,60.34％) and surgical (n =2 017,30.31％).Patients' average age was 46.90 ± 18.70 (14-99) years old and there were more patientsaged from 30 to 39 (n =1 285,19.56％).Hospital crowded periods were between 8:00-11:00 and 17:00-22:00.In these periods,average number of patients was more than 300.Concerning the severity of disease,83 patients (1.26％) were in grade 1 (the most severe cases),301 patients (4.58％) in grade 2,1 500 patients (22.83％) in grade 3,and 4 685 patients (71.33％) were in grade 4 (the less severe cases).Most ambulatory patient represented trauma (n =124,35.23％),neurological (n =68,19.32％) and cardiovascular (n =49,13.92％) diseases.However,50.57％ of them were not considered urgent.Conclusions Most patients visited emergency department were nonurgent and originated from medical and surgical department in Tianjin.Crowded periods gathered at 8:00-11:00 and 17:00-22:00.Most ambulatory patients were trauma,neurological and cardiovascular disease;however,half of them was stable and need no emergency intervention.

Objective To measure the fractional anisotropy(FA) values in the language function areas(Broca area,Wernicke area and arcuate fasciculus)by diffusion tensor imaging(DTI),discussing the pathological characteristics in cerebral palsy children with language development delay.Methods DTI was performed in twenty-seven cerebral palsy children with language development delay(observation group) and 20 children with febrile seizures(control group) by Philips 3.0T MRI scanner.The FA values of Broca area,Wernicke area and arcuate fasciculus were measured at Philips Workstation.Results The FA values of control group in the left Broca area,Wernicke area and arcuate fasciculusis were higher than those of the right side,and the difference was statistically significant (all P ＜ 0.05).The FA value of observation group in the left Broca area was lower than that of the right side,and the difference was statistically significant (P ＜ 0.05);the FA values of observation group in the left Wernick area and arcuate fasciculusis were higher than those of the right side,but the difference was not statistically significance (all P ＞ 0.05).The FA values in the bilateral Broca area and arcuate fasciculusis of observation group were lower than those of the control group,the difference was statistically significant (P ＜ 0.05),those in the bilateral Wernick area were also lower than the control group,but the difference was not statistically significant (P ＞ 0.05).Conclusions The main pathogenesis for language development delay in cerebral palsy children was extensive damage in language functional areas,and Broca area and arcuate fasciculus were markedly impaired than Wernick area.

Objective To observe the effects of hemoperfusion on homeostasis in patients with acute poisoning.Methods The data of 26 acute poisoning patients treated with hemoperfusion were retrospective analyzed.The clinical data included blood pH,PvCO2,PvO2,blood lactate,potassium,free-calcium,bicarbonate and blood glucose assayed and recorded at 0 min,30 min and 120 min after hemoperfusion.The statistical software SPSS 18.0 was utilized to analyze the statistical differences in the above biomarkers among three different intervals after hemoperfusion.Results At the beginning of hemoperfusion therapy,levels of homeostasis indicators were pH (7.36 ± 0.05),PvCO2 (41.0 ± 8.8) mmHg,PvO2 (37.0 ± 11.8)mmHg,lactate (1.35 ± 1.00) mmol/L,potassium (3.1 ± 0.5) mmol/L,sodium (136.3 ± 4.8)mmol/L,free-calcium (0.95 ± 0.11) mmol/L,blood glucose (7.90 ± 3.47) mmol/L,bicarbonate (22.8±3.3) mmol/L.At30min,the levels of those were (7.36±0.04),(40.0±5.7) mmHg,(41.0±7.5) mmHg,(1.11 ±0.57) mmol/L,(3.1±0.4) mmol/L,(137.3 ±5.4) mmol/L,(0.94 ±0.12) mmol/L,(6.20 ± 1.55) mmol/L,(22.2 ±2.3) mmol/L,respectively.At 120 min,the levels of those were (7.35 ± 0.06),(38.0 ± 6.7) mmHg,(46.0 ± 7.9) mmHg,(0.69 ± 0.52)mmol/L,(3.0±0.4) mmol/L,(137.3±5.0) mmol/L,(0.97±0.10) mmol/L,(5.88±1.43)mmol/L,(22.0± 2.2) mmol/L,respectively.Apparently,there were significant statistical difference in PvO2,lactate and blood glucose (P ＜ 0.05) among three different intervals,and no significant statistical differences in other indicators (P ＞ 0.05).Conclusions There were no significant effects of hemoperfusion on relevant indicators in acute poisoning patients.

Cardiopulmonary resuscitation is the most comonly used method facing cardiac arrest.The 2010 CPR guidelines emphasized high quality chest compressions and recommended continuous compression for 2 minutes after defibrillation to minimize interruptions in compressions.However,starting chest compressions immediately after a defibrillation shock may be harmful,if the heart is providing spontaneous beats and being subjected to external compressions at the same time.So it is very important to recognize ROSC during CPR,the methods of which include touching the pulse,amplitude spectral area,partial pressure end-tidal carbon dioxide,coronary perfusion pressure,central venous oxygen saturation,chest compression fraction,regional cerebral oxygen saturation,photoplethysmography,conjunctival oxygen tension,transthoracic-impedance plethysmography and echocardiography.This paper gives a review of the ROSC prognosis and recognition methods during CPR.

The elasticity of the ascending aorta in healthy volunteers and hypertension patients were examined by using quantitative tissue velocity imaging (QTVI), and the age-related change in the ascending aortic elasticity was investigated. The anterior and posterior walls of the ascending aorta were imaged with tissue Doppler method in all the subjects and QTVI was performed. Stable curves were obtained from 173 hypertension patients and 185 healthy adults. The peak early diastolic velocity (V(e)), peak late diastolic velocity (V(a)) and peak systolic velocity (V(s)) were measured. The relation of age with these measures was assessed. The results showed that the elasticity of the ascending aorta was much lower in the hypertension patients than in normal controls (P<0.05), and the elasticity was decreased with age in both groups (P<0.05). Our results suggested that QTVI, a new non-invasive ultrasonic technique, is helpful for the assessment of the aortic elasticity in hypertension patients.

OBJECTIVE:To study the time-effect and dose-effect of paeonol on the apoptosis of knee osteoarthritis(OA)artic-ular chondrocyte in rabbits and the mRNA expression of its related protein Bcl-2 and Bax. METHODS:60 big-ear rabbits were ran-domly divided into normal (normal saline) group,model (normal saline) group,paeonol high-dose,medium-dose and low-dose groups and triamcinolone acetonide(positive drug)group,with 10 rabbits in each group. Except for normal group,OA model was induced by right knee anterior cruciate ligament (ACLT) and the medial meniscus 1/3 resection in those groups. After modeling, different doses of paeonol(0.8,0.4,0.2 mg/kg),triamcinolone acetonide 0.2 mg/kg were injected into right articular cavity twice a week. 4 weeks and 8 weeks after administration,articular cartilage specimens were collected. Ultrapathological structure changes of articular chondrocytes were observed by electron microscope. Apoptosis of cartilage cell was observed by TUNEL and apoptotic index was calculated. mRNA expression of apoptosis related genes of Bcl-2 and Bax in articular cartilage tissue of rabbits were de-tected by in situ hybridization technique. RESULTS:Compared with normal group,articular chondrocyte of model group showed early and middle stage apoptosis morphology change after 4 and 8 weeks,and apoptosis index increased significantly and the mRNA expression of Bcl-2 and Bax was up-regulated (P<0.01);4 and 8 weeks later after administration,compared with model group,apoptosis index decreased and mRNA expression of Bax was down-regulated in paeonol groups,while mRNA expression of Bcl-2 was up-regulated(P<0.05 or P<0.01). Electron microscopy ultrastructural observation showed articular chondrocyte of pae-onol high-dose and middle-dose groups were in early stage of apoptosis.CONCLUSIONS:Paeonol can slow down articular chondro-cyte degeneration and destroy in OA model rabbits in time and dose dependently. Its mechanism may be associated with expression up-regulation of Bcl-2 and expression down-regulation of Bax.

Purpose To explore the immunohistochemical ( IHC) expression of ALK antibodies with different clones in anaplastic lym-phoma kinase ( ALK) gene fusion non-small cell lung cancer ( NSCLC) . Methods ALK expression in 60 NSCLCs were detected by IHC including autostainer (D5F3, Ventana+BenchMark) and manual staining using 4 different antibodies of D5F3 (Ventana), D5F3 (Cell Signaling), 1A4/1H7 (OriGene), 5A4 (Abcam), and all cases were verified with ALK FISH. Their expressions with 4 anti-bodies were compared with those by D5F3 (Ventana+BenchMark). Results 32 ALK gene rearrangement NSCLCs and 28 negative cases were identified by FISH and D5F3 (Ventana+BenchMark). The sensitivity of D5F3 (Ventana), D5F3 (Cell Signaling), 1A4/1H7 (OriGene), 5A4 (Abcam) was 93. 8%, 84. 4%, 93. 8%, 56. 3%, and all the speciticity was 100%. The consistency with D5F3 (Ventana+BenchMark) was 96. 7%, 91. 7%, 96. 7% and 76. 7%, respectively. The validity of immunohistochemical staining in surgical resection specimens was better than in small biopsies. Conclusion Effective routine manual immunohistochemistry with high-affinity antibody clone may provide a more economic and widespread pre-screening technique.

Objective To investigate the experience of exercise rehabilitation in patients after coronary artery bypass surgery, in order to provide reference for the effective development of exercise rehabilitation. Methods A total of 16 patients undergoing coronary artery bypass surgery in the Tenth People's Hospital of Shanghai from March 2017 to April 2017 were selected. A qualitative study of phenomenological method was used to conduct in-depth interviews on postoperative rehabilitation training demands. Results Four themes for exercise rehabilitation related demands after coronary artery bypass grafting was extracted: the demand of personalized rehabilitation guidance, continuous rehabilitation guidance after discharge, the expectation of family, social care and support, and the hope to establish hospital and community medical institutions joint service mechanism. Conclusions Patients who participate in rehabilitation after coronary artery bypass surgery have high demand for the related knowledge, high dependence on society and family and high demand for post-discharge rehabilitation. Nursing staff should implement targeted nursing measures according to the actual needs of patients so as to promote their early recovery.

To explore the automated immunostainer screening anaplastic lymphoma kinase (ALK) gene fusion non-small cell lung cancer (NSCLC) and clinicopathological characteristics of the molecular subtype lung cancers. Methods Five hundred and sixty-six cases of NSCLC were collected over a 16 month period. The test for ALK was performed by Ventana automated immunostainer with anti-ALK D5F3. The histological features, treatment and outcome of patients were assessed. Results Thirty-eight cases (6.7%, 38/566) of NSCLC showed ALK gene fusion. The frequency of ALK gene fusion was higher in male (7.1%, 25/350) than that in female (6.0%, 13/216) patients, but not achieving statistical significance (chi2 = 0.270, P = 0.604). ALK + NSCLC was more significantly more frequent in patients < or = 60 years (9.9%, 28/282) than >60 years (3.5% , 10/284) of age. Histologically, the ALK + NSCLCs were mostly adenocarcinoma (81.6%, 31/38) , among which eighteen cases were solid predominant subtype with mucin production; nine cases were acinar predominant subtype; one case was papillary predominant subtype and three cases were invasive mucinous adenocarcinoma. The ALK + non-adenocarcinoma included three cases of squamous cell carcinoma, three cases of adenosquamous carcinoma and one case of pleomorphic carcinoma. Among the ALK + NSCLC patients, the number of non/light cigarette smokers (86. 8% , 33/38) was more than that of heavy smokers. Twenty-nine cases were stages III and IV; twenty-nine cases showed lymph node metastasis; twenty cases showed metastases mostly to brain and bone; and one case showed EGFR gene mutation coexisting with ALK gene fusion. Twelve of fifteen patients received crizotinib therapy and remained stable. Conclusions NSCLC with ALK gene rearrangement shows distinctive clinical and histological features. Ventana-IHC may he a feasible and valid technique for detection of ALK rearrangement in NSCLC.
