Objective To study the preliminary effect of sartorius iliac flap in repair of acetabulum defect for developmental dysplasia of the hip (DDH) in elder children.Methods We retrospectively studied 17 elder children with acetabulum defect in DDH at the age＞6 years old who received acetabular repair with sartorius bone flap in this hospital from 2014 to 2016.All patients with acetabulum defect in DDH were treated with open reduction in general anesthesia.Three-dimensional osteotomy under the femur rotor was conducted to correct the femoral anteversion and neck-shaft angle.According to the height of femoral head dislocation lines,femur tuberosity was shorten and fixied with steel plates,joint capsule was reconstructed,The iliac sartorius musculocutaneous flap was took to the upper edge of the acetabular to repair the acetabular defect.The lower extremities were treated with plaster for 6 to 8 weeks after surgery.The hip joint function was trained and the function was evaluated with Mckay's criteria.The hip joint morphological evaluation was performed with reference to Severin's X-ray standard.Results Seventeen patients were followed up for 6 to 29 months.Postoperative reduction of the femoral head was good,the head mortar inclusive was satisfactory;there were no wound infection and femoral head necrosis.According to Mckay's criteria,2 patients got excellent,13 good,and 2 fair,with the fineness ratio at 88.2％;According to Severin's critera:11 patients excellent.Conclusion The overturned sartorius iliac flap can repair acetabulum defect,promote bone healing,and effectively improve acetabulum to cover head of femur.

Objective To study the characteristic of inhibition on platelet P2Y12 and short-term change after clopidogrel intake in patients with cardiovascular disease. Methods Thirty-two patients with cardiovascular disease were enrolled. Samples at baseline, 10 h and 36 h after 300 mg loading dose and 75 mg/d maintenance dose of clopidogrel with 100 mg/d Aspirin intake were measured respectively. Platelet aggregation (PAgT) was measured on thromboelastograph(TEG) induced by ADP/AA. INH was detected and calculated activated by Kaolin, AA, ADP and Activator((R)) in the TEG reagent. CD62p and VASP phosphorylation (PRI), platelet activation markers were tested with FACSCalibur Flow Cytometry, and platelet secretion activity and suppression of P2Y12 receptor were detected respectively. The changes of indicators were compared before and after clopidogrel intake, and evaluate their function in platelet receptor activation. Results INHADP at baseline was (11.5 ±9.3)%, and increased to (42.5 ±29.1)% statistically (t =3.155, P<0.05) after taking the P2Y12 at 10 h, but decreased to (20.4±13.1)% at 36 h, non-statistical to baseline (t = 2.078, P > 0. 05) , INHAA increases from baseline level (56. 6 ± 36. 6) % to (83.0 ±27. 3)% at 10h(t=2.086,P>0.05) and (85. 4 ±20. 8)% at 36 h (t= 1. 888, P>0.05), no statistical defferences were found. Inhibition on platelet activativation induced by ADP function well till 36 h after 300 mg loading dose. PAgTADP decrease from (53. 7 ± 14. 1)% at baseline to (49. 2 ±22. 8)% at 10 h non-statistically (t=0.656, P>0.05), and (40.7±12.8)% at 36 h statistically (t=2.418, P<0.05), however PAgTAA decrease at both 10 h and 36 h statiscally, from (34. 3 ± 18. 1) % to (17.4 ± 13. 1) % , (t=3.134, P<0.05) and (14.6±5.1)%, (t=2.532, P<0.05), respectively. Data of PAgT was not corresponding to that from TEG for the difference in sample type partly. PRI in VASP assay was (78. 6 ± 22.3)% before loading dose, and decreased to (70.7 ±9.4)% at 10 h without significance (t = l. 194, P>0.05) and (59.6 ±28.0)% at 36 h (t=1.930,P<0.05) statistically, similarly to INHADP,indicating that within 36 h clopidogrel did not have strong inhibitory effect on the ADP receptor. On the contrary, CD62p changed from (7. 5 ± 1. 4) % at baseline to (4. 2 ± 1. 1) % statistically (10 h, t = 18. 027, P < 0. 05) and ( 4. 3 ± 0. 2 ) % non-statistically (36 h, t = 2. 908, P > 0. 05 ). Inhibition of secretion activity reflected by CD62p was significant. In contrast, it was more obvious inhibition in COX-1 passway, while the inhibition of P2Y12 receptor varied due to assay difference. Conclusions AA-induced platelet activation is significantly decreased in the inhibition of clopidogrel and aspirin, while ADP receptor is significantly inhibited until 36 h after the loading dose of clopidogrel. Platelet function in whole blood reflects total activity of platelet interaction with other components, in which no significant inhibition could be witnessed within 10 h.

Apoptosis of PK-15 cells induced by Foot-and-Mouth Disease Virus (FMDV) in vitro was reported in this paper. Typical cell apoptosis was detected by use of Hoechst 33258 fluorescence probe, agarose gel electrophoresis and in situ end-labeling (TUNEL). After PK-15 cells were infected by titration of 4.8 lg TCID50/mL FMDV for 32 h, apoptosis characteristics of nuclear condensation, fragmentation, accompanied by apoptotic bodies formation (Hoechst 33258 staining), 180-200 integer-fold sized pieces DNA Ladders (agarose gel electrophoresis) and strong green fluorescence dots (TUNEL) were all exhibited, and cell apoptosis was approximately 20%. In addition, the quantitative analysis of apoptosis in PK-15 cells induced by FMDV showed that apoptosis was correlated with infection of virus, and it was also time-dependent. Results indicate that FMDV can induce apoptosis of host cells and apoptosis plays an important role in the cytopathogencity effect of FMDV.

Objective:To study the effect of total saponins on cerebral blood flow and vascular resistance in anesthetized dogs.Methods:Thirty hybrid dogs in either sex,with a body weight of(11?1.5)kg,were evenly randomized into 5 groups: negative control group(saline 5 ml/kg,ig),positive control(nimodipine 300?g/kg,iv),and 3 groups treated with total saponins (low-dose group[10 mg/kg,ig],middle-dose group[30 mg/kg,ig],and high-dose group[60 mg/kg,ig]).The dogs were anes- thetized with intravenous pentobarbital sodium(30 mg/kg).The right common carotid artery was exposed to measure the cere- bral blood flow,cerebral vascular resistance,blood pressure and heart rate using the MFV-3200 electromagnetic flow meter and MPA-3000 bioelectricity signal-amplifier.Results:Compared with negative control,cerebral blood flow was significantly in- creased in animals treated with asparagus root saponins(30 and 60 mg/kg,ig)during 5 and 120 min after drug administration (P

Objective To explore the mastery of relevant knowledge and skills for autism rehabilitation teachers in Beijing private rehabilitation agencies. Methods 51 autism rehabilitation teachers were selected from 10 Beijing private rehabilitation agencies and tested with self-prepared questionnaire. Results Rehabilitation teachers believed that professional knowledge, rehabilitation skills and special education basics ranked the former three positions as for knowledge importance; teachers' basic skills, professional knowledge and special education basics ranked the former three positions as for knowledge mastery. There were difference in academic background and business life. 95% teachers believed that the training form was knowledge plus case plus guidance. The best training time was weekends or summer and winter vacations. The curriculum expected mainly focused on behavior modification, class management, and training system that generally used for children with autism. Conclusion Autism rehabilitation teachers in Beijing private rehabilitation agencies urgently need training in the aspects of expertise, rehabilitation skills and so on.

OBJECTIVE: To observe cardiac ultrastructure and the expression of heat shock protein 70 (HSP70) and hypoxia inducible factor-lα (HIF-lα) in electric shock death rats and to explore the application of these indexes as the basis of medical identification in electric shock death. METHODS: Seventy-two SD rats were randomly divided into electric shock death group, postmortem electric shock group and the control group. The changes of myocardial ultrastructure were observed by transmission electron microscope, and the expressions of myocardial HSP70 and HIF-1α were observed by immunohistochemical technology. RESULTS: Myocardial myofibril fracture, mitochondrial cristae and membrane dissolution, and disordered arrangement of Z lines and M lines were observed in electric shock rats. HSP70 and HIF-lα were strong positive expressions in the electric shock death group, significantly compared with the control and postmortem electric shock groups (P < 0.05). CONCLUSION The expressions of HSP70 and HIF-lα were obviously increased in electric shock death group, which may be used as the diagnostic indicator of electric shock death.

OBJECTIVETo study the depression related factors in elderly patients after stroke and to explore the effect of Chinese medicine anti-depression treatment for improving neurological function in patients with after-stroke depression.

METHODSThree hundred and seventy-seven after-stroke elderly patients were sorted, according to their Hamilton Depression Scale-17 (HAMD17) scores, to the non-depression group (NDG, 116 patients) and the depression group (DG, 261 patients). The depression related factors in them were analysed. Moreover, patients in DG were randomly subassigned to two groups, the 135 patients in the treated group were treated with Chinese medicine and general stroke-treatment, and the 126 patients in the control group were treated only with general stroke-treatment for 4 weeks. HAMD17 scores of neurological deficit (NDS), scores of sleep dysfunction rating scale (SDRS), Hamilton anxiety rating scale (HAMA), and treatment emergent symptom scale (TESS) in them were observed before and after treatment.

RESULTSPrevalence rate of depression in patients with cerebral hemorrhage was 79.78% (71/89), significantly higher than that in patients with cerebral infarction, 65.97% (190/288, P < 0.05). Patients of stroke with lesion occurred at cerebellum, brain stem, or cerebral hemisphere (frontal lobe) and those with moderate/severe neurological deficit were more liable to suffer from depression. The HAMD17, HAMA, SDRS, and NDS scores in the treated group after treatment were all improved more significantly than in the control group (P < 0.05). NDS score reduced in the treated group significantly from 19.1 +/- 16.3 before treatment to 31.3 +/- 14.8 after treatment, showing the evident recovery of nerve function.

CONCLUSIONThe occurrence of depression after stroke is closely related with the nature and position of the lesion, as well as the degree of neurological deficit in patients. Chinese medicine could improve the depressive manner effectively and thus to make for recovery of neurological function.

OBJECTIVETo analyze the somnipathy related factors in elderly patients with stroke and to compare effects of traditional Chinese medicine and estazolam on sleep and the followed nervous function.

METHODSThe somnipathy related factors in 336 elderly patients with stroke, 221 accompanied with somnipathy and 115 with normal sleep, were studied and analyzed. Moreover, the 221 patients with somnipathy were assigned to two groups, 112 in the treated group treated with TCM according to syndrome differentiation, and 109 in the control group treated with estazolam. Changes of scores rated by neurological deficit scale (NDS), sleep dysfunction rating scale (SDRS), Hamilton anxiety rating scale (HAMA), Hamilton depression scale (HAMD), and treatment emergent symptom scale (TESS) were observed before and after treatment.

RESULTSThe occurrence of somnipathy in patients with cerebral hemorrhage was significantly higher than in those with cerebral infarction; it was higher in patients with lesion in brain stem, cerebral hemisphere (frontal lobe), or basal ganglion than in those with lesion in other sites; and patients with severe neurological deficit were more liable to having somnipathy. TCM showed a significant effect in improving the insomnia symptoms in patients, with the total effective rate reaching 81.25% (91/112), which was higher than that in the control group, 65.14% (71/109, P < 0.01). Along with the improving of sleep, marked recovery of the nervous function was shown in both groups, with NDS score reduced significantly (P < 0.05).

CONCLUSIONThe occurrence of somnipathy in stroke patients was closely related with the property and site of lesion, and the neurological deficit degree of patients. Better sleep is surely favorable for recovery of the nervous function, and TCM shows a favorable efficacy on somnipathy.

BACKGROUNDSubcapital femoral neck fracture in young adults has many complications, and the incidence is increasing year-by-year. The selection of the proper operation method to avoid them is an ambiguous matter. This study aimed to evaluate the treatment effect of subcapital femoral neck fracture by the capsulotomy and internal fixation with iliac bone grafting or closed reduction and internal fixation in young adults.

METHODSFrom March 2003 to February 2010, 65 young patients with subcapital femoral neck fractures were treated, including 39 males and 26 females with average age of 34.5 years (range, 19-50 years); 29 cases of the left side and 36 cases of the right side. They were randomly divided into Group A with 34 cases treated by closed reduction and internal fixation and Group B with 31 cases treated by the capsulotomy and internal fixation with iliac bone grafting. The two groups had no significant differences in sex, age, body mass index and preoperative Harris Hip Score. The observation criteria involved the length of the incision, blood loss, operation time, nonunion rate, avascular necrosis of the femoral head (ANFH) rate and Harris Hip Score.

RESULTSFour of 65 patients were lost follow-up, and the follow-up rate was 93.8%, the average follow-up time was 38.7 months (range, 33-47 months). In Group A, the incision length was 5.1 ± 2.2 cm, blood loss was 84.0 ± 13.2 ml, and operation time was 52.9 ± 10.2 min. In Group B, the incision length was 15.4 ± 4.6 cm, blood loss was 396.0 ± 21.3 ml, and operation time was 116.5 ± 15.3 min. Nonunion occurred in 8 patients (25.2%) in Group A and 1 patient (3.3%) in Group B. ANFH occurred in 9 patients (29.1%) in Group A and 2 patients (6.7%) in Group B. Postoperative Harris Hip Score was 89.0 ± 5.6 in Group A and 95.0 ± 4.5 in Group B. The above index of two groups was considered statistically significant (P < 0.05).

CONCLUSIONSCapsulotomy and internal fixation with iliac bone grafting can improve fracture healing, reduce ANFH in young adults. It is a safe and effective operation for subcapital femoral neck fracture.

OBJECTIVETo study the efficacy of traditional Chinese medicine (TCM) in treating somnipathy in patients with hypertension, and to observe the change of blood pressure after sleep being improved.

METHODSTwo hundred and thirty-nine patients with hypertension accompanied somnipathy were randomly assigned to two groups, 123 patients in the treated group were treated with TCM according to syndrome differentiation, and 116 in the control group treated with Estazolam. Changes of blood pressure, scores of sleep dysfunction rating scale (SDRS), Hamilton anxiety rating scale (HAMA) and treatment emergent symptom scale (TESS) before and after treatment were observed.

RESULTSTCM showed a significant effect on hypnagogic disturbance, and significantly reduced the scores of insomnia syndromes in early sleep stage, improve the quality of sleep, prolong the sleeping time to fulfill the physiological requirement, the total effective rate being 80.5% (99/123 cases), with the overall effect higher than that (66.4%, 77/116 cases) in the control group (P < 0.05). Along with the improving of sleep, blood pressure, both systolic and diastolic, reduced in both groups, but with the reduction in the treated group superior to that in the control group (P < 0.01), and the rate of reaching target BP (< 140/90 mmHg) in the former was also significantly higher than that in the latter (39.7%, 46/116 cases, P < 0.05). As compared with those in the control group, the occurence of adverse reaction, were less in the treated group (P < 0.05).

CONCLUSIONTCM has better efficacy in treating somnipathy of hypertension patients than Estazolam. And the improvement of somnipathy is favorable for improving the hypertensive condition of patient.
