For uncontrolled hemorrhagic shock the traditional method and target of resuscitation may be harmful. The existing data supported a strategy of less aggressive interventions to those shock with uncontrolled hemorrhage until a decisive surgery begin. The choice of liquor for resuscitation remains in controversy. A combined application of crystalloid and colloid liquor seems to be reasonable and may be accepted by most physicians. It should be noted that the new resuscitation strategy may not be suitable to some kinds of trauma, such as traumatic brain injury, and its long-term effects on to the prognosis should be further evaluated.

Objective To develop a new optometer controlled by micro-computer.Methods With AT89C51 single-chip as hardware and programmed by C language,the instrument applied,the optometer adopted LCD and international standard optotype.The optotype had 14 lines of object-finders,and only one line of random characters was displayed on the screen every time.The optometry distance was 3m.All procedures were controlled by singlechip.Results The case of memorizing eye-chart was avoided and the optometry was every simple.Conclusion The instrument eliminates mirror used for optometry short distance,and the optometry results can be stored and printed.It also has the merits of small volume,precise manufacture,simple operation,low cost and AC/DC power supply.

Objective To introduce the display principle and clinical application of PET-CT. Methods The display principle of PET-CT was analyzed. Results The status of tissue or organ were showed by using PET in the form of dissection images and the relative physiological parameters. Advanced CT technology exactly locates and indicates anatomic and functional information of target tissue or organ. Conclusion In combination of PET and CT, PET-CT show high value in clinical application.

OBJECTIVE: To discuss the clinical features, diagnosis and endoscopic surgical intervention for small steoma of nasal sinuses causing nasal and facial pain. METHOD: A retrospective review was performed on 21 patients with nasal and facial pain caused by small osteoma of nasal sinuses, and nasal endoscopic surgery was included in the treatment of all cases. RESULT: The nasal and facial pain of all the patients was relieved. Except for one ase exhibiting periorbital bruise after operation, the other patients showed no postoperative complications. CONCLUSION Nasal and facial pain caused by small osteoma of nasal sinuses was clinically rare, mostly due to the neuropathic pain of nose and face caused by local compression resulting from the expansion of osteoma. Early diagnosis and operative treatment can significantly relieve nasal and facial pain.

Objective To investigate the function of serum Interleukin-6 (IL-6) in the formation of cerebral edema after acute cerebral infarction through dynamic changes of serum IL-6 and MRI indicators.Methods One hundred and twenty-eight patients with cerebral edema after acute cerebral infarction and 30 healthy were selected as our subjects.The serum IL-6 were measured in at 1,5 and 14 d after acute cerebral infarction.MRI scans were performed in the corresponding time,and then processed synthesis of apparent diffusion coefficients (ADC) graph.Cerebral infarction volume,signal intensity ratio (SIR) of each sequence and relative apparent diffusion coefficient(rADC) were measured and calculated.Results The serum IL-6 in patients with acute cerebral infarction at 1 d after cerebral infarction was significantly higher than that in normal control group and reached the peak level at 5th D after cerebral infarction,significantly decreased at 14th d.The serum IL-6 of each time point were significantly higher than that of normal control group(P =0.000).There were liner positive correlation between the serum IL-6 and the volume of cerebral infarction and SIR of T2 weighted image and fluid attenuation inversion recovery (r =0.750,0.621,0.691 ; P =0.000).The serum of IL-6 and SIR of T1 weighted image was showed negative correlation (r =-0.404,P =0.000).The serum of IL-6 and SIR of diffusion-weighted imaging sequence at 1,5 d after cerebral infarction showed a positive correlation (r =0.678,P =0.000).There was liner negative correlation between the serum IL-6 and rADC at 1 d after cerebral infarction (r =-0.826,P =0.000).Conclusion The rise of serum IL-6 may promote the formation and development of ischemic cerebral edema.

Objective To improve the differential diagnosis between autoimmune pancreatitis (AIP) and pancreatic cancer (PC) by a contrast analysis of imageological features.Methods Thirty-six patients who had postoperative pathological with Asian AIP standards and 95 patients who had postoperative pathological consistent with PC.The imageological results of these AIP and PC patients were analyzed.Results AIP was significantly less than PC in the enhanced CT of a mass or enlargement of the pancreatic head,enlargement of the lymph nodes around the pancreas,dilation and interrupt in pancreatic and bile duct,peripheral vascular and organ involvement (11/27 vs.28/40,2/27 vs.17/40,13/27 vs.32/40,1/27 vs.10/40,8/27 vs.26/40,2/27 vs.15/40,0/27 vs.15/40,0/27 vs.10/40,P ＜ 0.05).AIP was significantly more than PC in the enhanced CT of a diffusely enlarged pancreas,calcification or pancreatic calculus,capsule-like rim or the vague peripancreatic fat interval (4/27 vs.0/40,7/27 vs.0/40,10/27 vs.6/40,P ＜ 0.05).AIP was significantly less than PC in the three-dimensional ultrasonography of dilation diameter of pancreatic duct and dilation of common bile duct [(0.421 ± 0.270) cm vs.(0.594 ± 0.270) cm,1/18 vs.16/26,P＜ 0.05].AIP was significantly less than PC in the magnetic resonance cholangiopancreatography of dilation of common bile duct and interrupt in pancreatic duct (7/13 vs.16/18,1/13 vs.10/18,P ＜ 0.05).Conclusion AIP as a unique type of chronic pancreatitis can be distinguished from PC on distinctive imageological features

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.
