Objective To improve level of first-aid treatment of severe head trauma and reduce fa-tality. Methods Clinical nursing procedures were applied to patients.Patients need first-aid treatment (105 cases) were divided into the control group(50 cases) and the experimental group(55 cases).The con-trol group adopted routine first-aid procedure,the experimental group was given first-aid nursing with self-designed shortcut nursing procedure for severe head trauma.The effect of application of shortcut nursing procedure was observed by comparing the fatality and time consumption of first-aid treatment between the two groups. Results The fatality and time consumption of first-aid treatment in the experimental groupwas lower than that of the control group, P<0.05. Conclusions Application of shortcut nursing proce-dure in first-aid treatment can not only improve level of first-aid treatment and reduce fatality, but also can instruct nurses how to rescue patients and improve their professional and vocational level.

OBJECTIVETo observe the effects of electroacupuncture (EA) on cochlea morphology and expression of aquaporin 1 (AQP1) in guinea pigs with endolymphatic hydrops, so as to explore the possible mechanism of EA on endolymphatic hydrops.

METHODSForty guinea pigs were randomly divided into a blank group, a model group, a medication group and an EA group, 10 guinea pigs in each one. Model of endolymphatic hydrops was established by using intraperitoneal injection of aldosterone. Guinea pigs in the blank group and model group were treated with identical immobilization as EA group but no treatment was given; guinea pigs in the medication group were treated with intragastric administration of hydrochlorothiazide at a dose of 5 mg/kg, once a day for consecutive 10 days; guinea pigs in the EA group were treated with' EA at "Baihui" (GV 20) and "Tinggong"(SI 19), once a day for consecutive 10 days. The serum ionic concentration in each group was tested by turbidimetric method; hematoxylin-eosin staining was used to measure the severity of cochlea hydrops; immunohistochemical method was used to observe the expression of AQP1 in the cochlea.

RESULTS(1) There was no endolymphatic hydrops in the blank group, moderate-severe endolymphatic hydrops in the model group and slight endolymphatic hydrops in the EA group and medication group. (2) The concentration of K+ and Ca2+ in the EA group was higher than that in the model group and medication group (all P<0. 01); the concentration of Na+ was lower than that in the model group (P< 0. 01) but higher than that in the medication group (P<0. 01); the concentration of Cl- was higher than that in the medication group (P<0. 01), but not significantly different from the model group (P>0. 05). (3) The ratio of expression area of AQP1 in the model group was lower than that in the blank group (P<0. 01); the ratio of expression area of AQP1 in the EA group was higher than that in the model group (P<0. 01), and lower than that in the medication group without significant difference (P>0. 05).

CONCLUSIONEA could relieve the endolymphatic hydrops in guinea pigs; the mechanism is likely to be related with up-regulating the expression of AQP1 in cochlea and ion concentration might be an important factor involved.

Hemodynamics is a discipline that studies the effects of blood flow,blood flow volume and other factors on the arterial wall.Intracranial aneurysm is the main cause of death due to non-traumatic subarachnoid hemonhage,which has brought a heavy burden on society.Therefore,it is very important to make an intensive study of the pathogenesis of aneurysm.With the development of medical imaging technology and fluid mechanics software in recent years,it becomes possible to make the precise and scientific studies of the hemodynamics of intracranial aneurysms.In this paper,the hemodynamic factors inducing the formation of intracranial aneurysm that are proposed by medical experts at home and abroad are reviewed,and the hemodynamic mechanism is discussed.

Objective The study was to investigate the spectrum and incidence of the hot-spot deafness gene mutations from non-syndromic hearing loss(NSHL)in Guizhou province.Methods Genomic DNAs of 356 patients of NSHI in Guizhou were obtained from peripheral blood and a deafness gene test chip was used to screen nine hot spot mutation in the gene GJB2,SLC26A4,GJB3 and mitochondria 12SrRNA.Results Eighty-eight (24.72%)out of 356 patients were found carrying at least one pathogenic gene mutation.Among them,40 patients with the GJB2 mutations were found(11.24%),including 19 cases(5.34%)of homozygous matutions,5 cases(1.40%)of com-pound heterozygous mutations,and 15 cases(4.21%)of single heterozygous mutations.Twenty-nine patients with the SLC26A4 mutations were found (8.15%),including 9 cases(2.53%)of homozygous mutations and 19 cases (5.34%)of single heterozygous mutations.Homogenic mitochondrial 12SrRNA 1555A>G mutations were in 10 patients(2.81%)and 1494C>T mutations in 10 patients (0.56%),and heterogeneous mitochondrial 12SrRNA 1555A>G mutations in 7 patients(1.97%).GJB3 gene c.538C>T heterozygous mutations was found in 1 patients. Conclusion The mutations of GJB2 and SLC26A4 gene are two major pathogenic genes for patients with NSHL in Guizhou province.Our study provides a theoretical basis for the early diagnosis,genetic counseling and treatment of deafness.

Objective:To evaluate the relationship betweenparacardial adipose tissue (PAT) volume, body mass index (BMI) and severe coronary artery stenosis in young people by quantitative measurement of 256-slice spiral CT.
Methods: A total of 150 patients younger than 45 years and received coronary angiography (CAG) in our hospital were divided into 2 groups:Lesion group, the patients with severe main coronary branch stenosis and Control group, patients with normal coronary artery. n=75 in each group. The height, body weight and BMI were recorded in all patients;imaging data was uploaded to the workstation to calculate the volumes ofepicardiumadipose tissue (EAT) volume,pericardial outsideadipose tissue volume and PAT volume, the correlation among 3 parameters were analyzed respectively.
Results:Compared with Control group, Lesion group had increased BMI (28.169±2.203) kg/m2 vs (24.960±3.041) kg/m2 and PAT volume (178.676±3.041) ml vs (99.0616±3.041) ml, all P<0.05. Compared with Control group,no matter male or female, Lesion group had larger PAT volume, P<0.01.EAT volume was related to pericardial outside adipose tissue volume (r=0.837, P<0.001) and PAT volume (r=0.971, P<0.001);pericardial outside adipose tissue volume was related to PAT volume (r=0.944, P<0.001).
Conclusion:PAT volume and BMI were obviously correlated to severe coronary artery stenosis in young people.
