Objective: To discuss the effect of early enteral nutrition support on immunological function in patients with acute stroke. Methods: Forty-nine stroke patients with dysphagia were randomly allocated into study group (n = 24) and control group (n = 25). They were received enteral nutrition via nasogastric tube and ordinary nasal feeding of liguid diet, respectively within 72 hours after admission. The levels of total lymphocyte count (TLC), immune globulin A (IgA), immune globulin G (IgG), immune globulin M (IgM), complement 3 (C3), and complement 4 (C4) in both groups were detected on day 1, 7 and 21 respectively after admission. The changes of nutritional index and the incidence of infective complications were observed. Results: The levels of TLC [(2.1 ± 0.4) × 109/L], IgA [(2.7 ± 0.5) g/L], IgG [(11.1 ± 2.2) g/L], IgM [(1.7 ± 0.7) g/L], and C3 [(1.2 ± 0.2) g/L] in the study group were significantly higher than the levels of TLC (1.7 ± 0.4 × 109/L, P < 0.05), IgA [(2.0 ± 0.4) g/L, P < 0.01], IgG [(8.9 ± 2.5) g/L, P < 0.01], IgM [(1.3 ± 0.6) g/L, P < 0.05], and C3 [(1.0 ± 0.3) g/L, P < 0.01] in the control group after 21 days. The incidence of infective complications in the study group (29.1%) was significantly lower than that in the control group (60.0%; P < 0.05). The nutritive index of the study group was also significantly better than that in the control group. Conclusion: Early enteral nutrition support may improve the immunological function in patients with acute stroke, and decrease the incidence of infective complications.

Objective To study the clinical characteristics of early esophageal varices bleeding after endoscopic varices liga-tion EVL in advanced schistosomiasis patients. Methods The data of 206 advanced schistosomiasis patients who received VEL were collected and studied retrospectively. Results There were 17 cases of early esophageal varices bleeding after EVL in-cluding 1 died case the early hemorrhage rate was 8.25% and the mortality rate was 0.5%. The early bleeding occurred from the 4th to 12th day and 76%occurred from the 7th to 9th day postoperatively. The direct cause of hemorrhagic was ligation ring falling off and the inducements were the improper diet 10 cases 58.8% and increased abdominal pressure 6 cases 35% . All the cases of early esophageal varices bleeding occurred in the patients whose liver function being Child-Pugh C. Conclu-sions The incidence and mortality of EVL early postoperative hemorrhage are both low and mostly occur from the 7th to 9th day postoperatively. We should pay attention to the diet and nursing and the patients with Child-Pugh C liver function are the high risk group.

Objective To evaluate the diagnostic value and limits of 64-slice spiral coronary artery imaging,by com- parison with selective coronary angiography,in detection of coronary heart disease.Methods Fourty-two patients sus- pected CAD were performed 64-slice spiral CT coronary imaging and selective coronary artery angiography in two weeks, comparative analysis of results were progressed consequently.Results The sensitivity,specificity and positive and nega- tive predictive value to identify≥50% stenosis branches was 90.5%,96.6%,85.9% and 97.8%,respectively.The sen- sitivity,specificity and positive and negative predictive value to identify≥75% stenosis branches was 93.5%,98.9%, 87.9% and99.4%,respectively.Conclusion As a noinvasive quantitative assessment of coronary artery stenoses exami- nation,64-slice spiral CT is a valuable method to detect and diagnose the disease of coronary artery,but its clinical use maybe presently be limited due to image quality in a number of cases.

Objective To explore the application of subdermal vascular network skin graft in severed finger reunion with small area skin defects.Methods Modified subdermal vascular network,which was inversion thin and middle thick,was used to repair defect of severed finger reunion without exposure of blood vessel.There were 10 patients and 14 fingers,including 7 patients and 10 fingers injured in the dorsal sid with 5 fingers' extensor tendon exposed,and 3 patients and 4 fingers injured in the palmar side with 2 patients' flexor tendon exposed.The defect area was ranged from 1.0 cm × 0.8 cm to 3.0 cm × 1.5 cm.Results In 6 larger subdermal vascular network,skin's edge became blue and blister appeared in the middle.The others was good with skin texture and aspect.Conclusions Modified subdermal vascular network skin graft is safe and effective choose to solve severed finger reunion with smnall area skin defects.

OBJECTIVETo investigate the differences in the condylar position of subjects with skeletal class I and skeletal class II. To provide a basis of diagnosis and treatment.

METHODSGroup A was composed of 50 subjects with skeletal class I (27 males and 26 females; age range = 18 years to 30 years; mean age=26 years). Group B comprised 50 subjects with skeletal class II (24 males and 26 females; age range = 18 years to 28 years; mean age=25 years). The condylar position and the shapes of the condyle and the glenoid fossa were linearly measured on the sagittal and coronal sections by cone-beam computed tomography (CBCT). Data were analyzed by SPSS 19.0.

RESULTSNo statistically significant differences were found in the measurements of the condylar position between the sides of each group on the sagittal plane and the coronal plane (P > 0.05). There were significant differences on the anterior space and the posterior space between group A and B (P < 0.05). The A/P joint space ratio of group A was larger than that of group B (P < 0.05).

CONCLUSIONThe subjects of skeletal class I show an anterior condyle position. The subjects of skeletal class II show a posterior condyle position.

Objective:To observe effect of acupuncture combined with hypothermia therapy on MAPK/ERK pathway and apoptosis related factorsin rats suffered cerebral ischemia reperfusion and to explore underlying mechanisms.Methods:Middle cerebral artery ischemia model were established.Ninety SD rats were randomly assigned into a blank group,a control group,a model group,an acupuncture group,a mild hypothermia group,and an acupuncture with hypothermia group.After 72 h treatment,nervefunction defect scores were observed,and infarction area percent was detected by 2,3,5-triphenyl-2H-tetrazolium chloride (TTC) staining;expressions of Bcl-2 and Bax were examined by immunohistochemistry;apoptotic cells were detected by TUNEL assay;and expression levels of phospho-mitogen-activated protein kinase(p-MEK2) and phospho-extracellular signal regulated kinase 1/2 (p-ERK1/2) in the rats' hippocampus ischemic side were determined by Western blot.Results:In the rats of the model group,the neural function defect scores,the infarction area percent,the expression level of Bax,and apoptotic cells increased,while the level of Bcl-2 decreased significantly.The level of p-MEK2 and p-ERK1/2 increased obviously compared with the blank and control groups (P＜0.05 or P＜0.01).After treatment with acupuncture and hypothermia,the neural function defect scores,infarction area percent,and the level ofBax,apoptotic cells and the levels of p-MEK2 and p-ERK1/2 were significantly decreased,while the level of Bcl-2 in the treatment group was significantly elevated (P＜0.05 or P＜0.01) compared with the model group.Compared with the acupuncture group or the hypothermia group,the neural function defect scores and the levels of p-MEK2 and p-ERK1/2 in the acupuncture combined with hypothermia group were significantly reduced (P＜0.05 or P＜0.01).Conclusion:Acupuncture and hypothermia therapy can improve cerebral function,and reduce the cerebral injury through down-regulation of Bax level,and up-regulation of Bcl-2 level,which is related to reducing the levels of p-MEK2 and p-ERK1/2.The therapeutic effects on cerebral ischemia reperfusion injury for combination of acupuncture with hypothermia are better than those with single application of acupuncture or hypothermia.
