ABSTRACT:OBJECTIVE To observe antithrombotic effects of panax notoginseng saponins plus aspirin via applying throm-boela-stogram(TEG).METHODS 5 1 patients with senile coronary heart disease were randomly divided into treatment group and control group,with patients in the control group being given aspirin while whose in the treatment group being treated with Sanqi Tongshu Capsule and aspirin.TEG of both groups were observed together with platelet inhibition rate(AA%)induced by arachidonic acid.There existed a statistical significance between the two groups in improving R value,K value and alpha Angle (P <0.05~0.01).RESULTS Reducing scores on SDRS and HAMA of the treatment group before and after treatment were evidently higher than those of the control group(P <0.01).Both groups were effective in improving PSG parameters including sleeping time,sleep latency and sleep efficiency after treatment(P <0.05),but the treatment group was superior to the control group(P <0.05).The total curative rate of treatment group and control group were 84.85% and 67.74% respectively with a statistical significance between the two groups(P <0.05).CONCULSION Panax notoginseng saponins plus aspirin is superior to aspirin in anti-thrombosis,without increasing the side effects.

Objective To evaluate the clinical value of multi-slice CT(MSCT)angiography in the diagnosis of Takayasu's arteritis.Methods Fourteen patients underwent MSCT angiography with use of 90 ml contrast media at a rate of 3.5 ml/s.Images were generated for vascular assessment with various reconstructional techniques,including multi-planar reformat(MPR),maximum intensity projection(MIP), volume rendering(VR),CT virtual endoscopy(CTVE)and advanced vessel analysis(AVA).Results MSCT angiography findings was consistent with the clinical changes of Takayasu's arteritis in all cases.The integrated information including reconstructional and transverse images clearly presented various luminal abnormalities,such as stenosis,occlusion and dilatation in the affected aorta,as well as its major branches and collateral circulation.Furthermore,it depicted mural abnormities,especially concentric arterial wall thickening.Steno-occlusive type(8/14)was more common than mixed type(6/14).According to Lupi- Herrea's classification,type Ⅰ in 5 cases,type Ⅱ in 2,type Ⅲ in 6 and type Ⅳ in 1 were recorded in the present study.Conclusion MSCT angiography is reliable imaging modality for the detection of Takayasu's arteritis.It is useful for early diagnosis because it allows evaluation of wall thickness rather than merely the luminal diameter,which is especially important for prognosis.It might be used as the first choice in the diagnosis of this disease as a simple,convenient and noninvasive method.

OBJECTIVETo explore the therapeutic effect and mechanism of abdominal acupuncture for cervical spondylosis of vertebral artery type.

METHODSThirty cases of cervical vertigo, in which the color ultrasonography indicated vertebral arterial blood insufficiency, were treated with abdominal acupuncture therapy. The points were Zhongwan (CV 12), Qihai (CV 6), Guanyuan (CV 4), Xiawan (CV 10), Shangqu (KI 17) and Huaroumen (ST 24). The treatment was given once every day and five continuous treatments made one session. Separately, before treatment and in the 1st and 5th treatments, the cervical vertigo symptom and functional assessment scales were adopted for scoring. Simultaneously, the color ultrasonography was applied to observe the blood flow changes of the bilateral cervical arteries.

RESULTSExcept the score for headache in the 1st treatment, the scores in cervical vertigo and function assessment scale in the 1st and 5th treatments were all improved significantly in 30 patients as compared with those before treatment (P < 0.01, P < 0.05). In the 1st and 5th treatments, on the affected side, the vertebral artery diameter, mean velocity and blood flow per minute were all improved significantly as compared with those before treatment (all P < 0.01). In one session treatment, the total effective rate was 100.0% (30/30) and the curative rate was 60.0% (18/30).

CONCLUSIONAbdominal acupuncture therapy not only relieves the clinical symptoms, but also improves vertebral arterial blood supply for the patients of cervical spondylosis of vertebral artery type.

We studied on the bio-safety problem of cultivating innovative talents in medical microbiology. The bio-safety of laboratory was controlled by educating bio-safety before the experiments, regulating basic operations during the experiments and constructing management system out of the experiments. Then we got some experience to ensure students’ bio-safety during the research.

OBJECTIVETo constitute a model of B immunoblastic lymphomas in the Hu-PBL-SCID mice.

METHODSThe SCID mice were reconstituted by intraperitoneal injection (i.p.) of 5 x 10(7) human lymphocytes from Epstein-Barr virus (EBV) seronegative individuals. After one week, the SCID mice were inoculated with EBV by i.p. injection, and subjected to the investigation of whether there was any tumor in the abdomen of such SCID mice four weeks later. The characteristics of the found tumor was observed by the methods of Hematoxylin-eosin (HE) stain, immunohistochemical staining and polymerase chain reaction (PCR).

RESULTSCompared with the control groups, all the EBV-infected Hu-PBL-SCID mice had abdominal solid tumors [(32 +/- 12.5) mm3] developed, often located in the liver. HE staining and immunohistochemical staining showed the tumors were human B cell lymphomas. EBV DNA could be detected in the tumors by the PCR.

CONCLUSIONSThe model of B immunoblastic lymphomas in the Hu-PBL-SCID mice is successfully constituted, and may well be useful to the human tumor immunological study.

BACKGROUNDMultiple epiphysis dysplasia (MED) is a common skeletal dysplasia with a significant locus heterogeneity. In the majority of clinically defined cases, mutations have been identified in the gene encoding cartilage algometric matrix protein (COMP).

METHODSFive patients were included in the study. Linkage analysis and mutation analysis of the COMP gene were conducted in the patients and their family members.

RESULTSWe have identified a novel mutation in axon 14 of COMP gene in the family.

CONCLUSIONSThis mutation produced a severe MED phenotype with marked short stature, early onset osteoarthritis, and remarkable radiographic changes. Our results extended the range of disease-causing mutations in COMP gene and contributed more information about relationship between mutations and phenotype.

Objective To investigate the effect of the continuous care support intervention on breast cancer patients with radical mastectomy.Methods Totals of 107 patients undergoing elective radical mastectomy were randomly divided into intervention group ( n =54 ) and control group ( n =53 ).Both of two groups of patients were treated on the basis of conventional care according to the doctors' advice before and after surgery.The intervention group received the continuous individual nursing intervention model,included preoperative interactive support intervention,postoperative pain assessment support intervention and rehabilitation support intervention after discharge. Intervention effects of two groups were observed and compared. Results The anxiety,positive response and negative response of two groups patients were no significant differences before intervention (P＞0.05).After intervention,the scores of anxiety,positive response and negative response in intervention group respectively were (35.28 ± 5.43 ),(39.82 ±4.03 ) and (25.61 ± 5.12),and that of control group were (42.73 ± 6.72),(33.15 ± 5.62) and (31.75 ± 6.38),and the difference was statistically significant ( t =6.313,7.065,5.495,respectively; P ＜ 0.01 ).The duration of postoperative different period pain score,first off the bed time,sleep time,upper extremity swelling and hospitalization days were statistically significant between two groups (P ＜0.01 ).And the postoperative recovery state of upper limb function after six months,and life quality score after one year in intervention group were significantly better than that of control group ( P＜0.01 ).Conclusions Continuous individualized specialized nursing intervention support model can promote physical function in patients with early recovery and improve quality of the prognosis life and the treatment outcome.

Objective To investigate the effect of comprehensive nursing intervention on the treatment of common bile duct stones undergoing endoscopy.Methods A total of 137 patients with common bile duct stones undergoing the endoscopic treatment were randomly divided into intervention group (n =69 cases) and control group (n =68 patients).All the patients received routine care before and after the endoscopic treatment.In addition,the patients in the intervention group received audio-visual training intervention with preoperative,music therapy with intra-operative and position training intervention with postoperative.The intervention effect was compared between the two groups.Results Breath rate,heart rate,oxygen saturation before treatment were not different in the two groups (P＞0.05).Breath frequency in intervention group after treatment was (23.6 ±3.4) time/min,the first bed time was (19.24 ± 3.67)h,extubation rate was 97.10％ and complication rate was 4.35％ and those in control group were (28.9 ± 3.7) time/min,(24.62 ±4.81 ) h,86.76％ and 16.18％respectively,and the differences were significant ( t =8.72,7.35 ; x2 =4.96,5.03 ; P ＜ 0.05 ).Heart rate,blood pressure in experimental group after treatment were reduced and the extubation time and in hospital time were shorten than control group,however,the sleeping time was longer in experimental group (P ＜ 0.05).Conclusions Comprehensive nursing intervention can improve treatment compliance,promote patients' early recovery and achieve the desired effect.

BACKGROUND: Acetabular defect is one of the typical characteristics of adult developmental dysplasia of the hip. The acetabular defect caused an insufficient coverage to the femoral head, which means the contact area between them decreased and the pressure increased. Stress concentration could quicken hip wear and lead to arthritis or dislocation of the hip. Till now, there is no accepted objective criterion about what degree defect could lead to biomechanics changes in the hip. OBJECTIVE: To analyze the influence of different degrees of acetabular defect on the stress distribution of hip joint by using three-dimensional finite element method, and provide theoretical guidance for clinical treatment of hip dysplasia. METHODS: CT thin layer scanning data of normal adult hip were selected. Hip dysplasia models with varying degrees of bone defect were built by using Mimics15.0 and Hypermesh software. Von Mises stress distribution on the subchondral bone of the hip was analyzed by using Ansys10.0 software in the case of single foot touchdown. RESULTS AND CONCLUSION: Each model result was consistent with the actual situation. The maximum Von Mises stress value appeared at the top of the acetabulum dome and medial posterior femoral neck. When simulating one leg standing, the smaller the CE angle, the greater the maximum Von Mises stress on femoral head was; and acetabulum increased from 2.768 MPa and 3.029 MPa with 30° CE angle to 11.075 MPa and 15.322 MPa with 5° CE angle. This change was more obvious when CE angle was less than 15°. These findings confirmed that acetabular defect increases the peak stress of the hip joint, and the greater the defect, the greater the stress was. It is suggested that clinical intervention should be done as early as possible in patients with acetabular defect.
