[Objective]To study the injury mechanism of sacral plexus resulting from sacral zone-Ⅱ fractures of lateral compression.[Method]Six short-term(in a year) embalmed pelves were obtained from anatomic department of Hebei Medical University with preserving sacral plexus and resecting pubic symphysis,the models of sacral zone-Ⅱ fractures of lateral compression were produced.Quantitative analysis for fracture displacement was carried out to observe the characteristic and the mechanism of sacral plexus injury.Sacral plexus were replaced by proportional diameter silica gel pips fulled with contrast medium,experimental procedure was repeated under X-ray.The experimental data were analyzed by SPSS10.0 statistic software and the result was obtained.[Result]In lateral compression type sacral canal was closed and its volume reduced and small free fracture segment resulted in sacral plexus nerves oppressed,especially of L_5,Sland S_2.At the same time,the more overlapping of pubic symphsis,the more serious of compression.[Conclusion]Sacral plexus is conncted with the wall of pelvic cavity and fixed.Zone-Ⅱ sacral fracture is likely to damage sacral plexus.In lateral compression type of sacral fracture nerve injury is mainly compression injury which position is in nerve canal,especially of S_1,S_2.And L_5 can be crushed in fracture interspace to be damaged seriously.

Objective:to combine psychotherapy and medication in treatment of tension-type headache Method:84 patients with tension-type headache were randomly divided into study group (combining psychotherapy with medication) and control group (medication only) The psychotherapy was twice to three times a week, for 2 or 3 weeks and then follow up for at least 1 year Result:in the study group, the rate of improvement was 95%, that of marked improvement was 67%, were significantly higher than the counterparts in control group (were 69% and 38% respectively) Conclusion:combining psychotherapy with medication is more effective than medication only in treatment of tension-type headache

Objective:To observe the clinical efficacy of Shenfu Injection for the most gastric resection.Methods: ASA II-III patients undergoing elective surgery for 60 patients with subtotal gastrectomy, were divided into experimental group, control group randomly. The experimental group was divided into Shenfu group (A), the control group treated with dopamine (B). In the A group before induction of anesthesia with intravenous injection of 0.8ml/kg of Shenfu injection,and group B received balanced salt to maintain anesthesia, the disposal of the same. Patients were given dopamine, atropine and other vasoactive drugs, there were recorded before anesthesia(T0), immediately after tracheal intubation (T1), 30min after intubation (T2), 1h after intubation(T3) hemodynamics.Results: Compared with the control group, the experimental group canachieve hemodynamic stability time earlier, smaller influence on the fluctuation of blood pressure.Conclusion: Shenfu Injection on patients with coronary heart disease underwentsubtotal gastrectomy to improve the stability of circulation system.

Objective To understand the inhibitory control in children with functional articulation disorder (FAD).Methods 30 children who met the criteria of FAD aged of 4-6 years were selected as the case group,and 30 normal speaking children matched in age were selected as the control group.The inhibitory control function were examined by handgame and day-night stroop task.The data were described as median (P25,P75) and the differences were compared between the two groups by rank test.Results The scores of handgame (4(3,5)) and day-night stroop task(13(11,16)) in case group were much inferior to those in control group (5 (4,5),15 (14,15)) (P＜0.05).Conclusion The inhibitory control of children with functional articulation disorder was much inferior to normal children.

Chronic exposure to risk factors at the beginning stage of atherosclerosis development can damage endotheli?um and ultimately initiat endothelial dysfunction. Endothelial dysfunction is one of the major mechanisms in atherosclerosis development. High-density lipoprotein (HDL) is a lipoprotein with complicated function and is composed of a variety of pro?teins and lipids. Epidemiological studies showed an inverse correlation between HDL and atherosclerosis. The protective role of HDL on endothelium might related to its function in reversing cholesterol transport, reducing peripheral cholesterol accu?mulation, preventing foam cells formation, dilating vessels, antioxidant and anti-inflammation, all of which antagonize devel?opment of atherosclerosis. But HDL obtained from patients with cardiovascular disease which has known dysfunctional HDL may induce endothelial dysfunction. This review addresses the relationships between functional HDL or dysfunctional HDL with the endothelial function.

Objective To discuss the relationship between C-reactive protein and prognosis of acute coronary syndrome. Methods C-reactive protein of 60 acute coronary syndrome patients was evaluated. The individuals were divided into two groups:One group with higher CRP level and another group with normal CRP level. The following-up duration was 6 months. After correct therapy, the morbidity of re-angina, arrhythmia, heart failure, re-infarction and cardiac death was compared. Results The morbidity of re-angina, arrhythmia, heart failure, re-infarction, cardiac death was 46.3%(19/41), 43.9%(18/41),9.76%(4/41),22.0%(9/41),7.32%(3/41)respectively in higher CRP level group; The morbidity of re-angina, arrhythmia, heart failure, re-infarction was 15.8%(3/19),10.5%(2/19), 5.3%(1/19),5.3%(1/19)respectively in normal CRP group and there was no cardiac death accident. There was significant different between the two groups. Conclusions CRP plays an important role in the onset of acute coronary syndrome, and its level is related with the higher morbidity of re-angina, arrhythmia, heart failure, re-infarction and cardiac death.

ObjectiveTo observe the effect of continuous passive motion (CPM) on postoperative functional rehabilitation in lower limb.Methods267 patients operated in lower limb were separated to CPM group (162 cases) and control group (105 cases). Patients of the CPM group used CPM device at early period post operation, and cases of the control group received instruction to exercise by themselves. The efficacy of two methods was evaluated.ResultsThe knee activity of affected extremity of CPM group at 10 day and 1 month was better than that of control group, as well as the rate of swelling extinction of affected extremity (P<0.05～0.01).ConclusionIt is propitious to functional rehabilitation of patients operated in lower limb that using CPM early post operation.

Prevention of infection by the human papillomavirus (HPV) has become a hot research topic since the relationship between the HPV and cervical cancer was confirmed. Persistent infection with HPV and early expression of proteins has an important role in the pathogenesis of cervical cancer. Vaccines that protect against four high-risk types of HPV (-6, -11, -16, -18) have been used worldwide. A bivalent vaccine (HPV-16 and -18) developed by Walvax is in clinical trials. This study reviews progress in ascertainment of the structure and function of the HPV genome, the molecular mechanism of carcinogenesis, and vaccines based on virus-like particles.

Objective To discuss the nurses'satisfaction degree with work and its influencing factors and analyze the difference of nurses'satisfaction degree with work with different background.Methods 398 nurses in a certain comprehensive hospital were investigated with Mueller/McCloskey(MMSS)satisfactory inventory. Results The nurses'general satisfaction degree with work was less than middle level with a score of (3.12±0.46).The satisfaction degree was statistically different in different dimensionality and nurses with different background. Conclusion The management department of hospitals should adopt positive measures to improve the nurses'satisfaction degree with work and prompt them to supply more high-quality and effective nursing services.

Objective: To evaluate the application of two-dimension and color Doppler ultrasound in diagnosis and differential diagnosis of fascial space infection in maxillofacial region. Methods: Retrospective analysis was conducted on 87 cases of maxillofacial space infections, among which there were 6 suspected cases of accompanying tumor.Results: In the 87 cases, 53 had abscess formation, confirmed by operative drainage or puncture biopsy. The pathological studies revealed 2 cases of Non-Hodgkin's lymphoma, and 1 case of branchial cleft cyst accompanied with infection. The 3 cases showed characteristic appearance in ultrasonic imaging. The space infection presented stronger echogenicity than that in tumors. In this study, 95% (83/87) cases showed grey or medium echogenic dots, while 4.5% (4/87) cases did not show obvious echogenic dots due to a large amount of abscess, and 2 cases of tumors, however, did not show any echogenic dots. In addition, 87% (76/87) cases had few blood flow in the lesion areas, and 22% (2/87) cases had much blood flow in the lesion areas. All cases showed that the lesion areas and the blood flow reduced obviously with enhanced echo following anti-inflammatory treatment except 2 cases accompanied with tumor without obvious changes in lesion areas and blood flow.Conclusion: The ultrasonic diagnosis with two dimension and color Doppler ultrasound has high accuracy in diagnosis of maxillofacial space infection, with accordance rate up to 96.6%, much higer than CT/MRI. It is suggested that the two dimension and color Doppler ultrasound can be used as a prior choice of diagnosis.
