Objective To observe the effect of Lovastatin on carotid atherosclerotic plaque(CAP),levels of blood lipid and serum C-reactive protein(CRP) in patients with cerebral infarction(CI).Methods 120 CI patients with CAP were randomly divided into Lovastatin group and control group.At the basic of low fit diet for the two groups,Lovastatin was taken with 20 mg once a day for 6 months in Lovastatin group.Then,the changes of paque score,the levels of CRP and blood-lipid were observed 8 weeks and 6 months after treatment.Results (1)6 months later,the plaque score(4.20?3.77) in the Lovastatin group was significantly lower than pro-treatment(4.77?2.31)and the control group(6.86?1.89) (all P

Objective To analysis the effect of using comprehensive rehabilitation treatment for osteoporotic bulging disc combine diabetes otients.Methods Ninety cases osteoporotic bulging disc combine diabetes patients, who treated in Guanganmen Hospital of Chinese Academy of Traditional Chinese Medicine from January 2011 to January 2011, were randomly divided them into observation group and control group, 45 cases in each group, control group was given conventional treatment, the observation group was given comprehensive rehabilitation treatment, compare visual analogue scale (VAS) score and Oswetry functional disability index (ODI) changes in two groups after treatment, and compared the efficient of treatment.Results VAS scores after treatment for one course and 2 courses in observation group were respectively (2.05± 1.31) and (1.26± 1.03) points,ODI score was respectively (26.37±5.10) and (21.82±4.57) points, VAS score in the control group was (5.85±1.38) and (3.29±1.94) points,ODI score was respectively (37.29±6.32) and (28.33±5.30), all obviously improving than before treatment, but compared with control group, the observation group improved more apparent,the difference between groups was statistically significant(P＜0.05).Treatment effective rate in observation group was 95.56％ (43/45), the control group was 80.00％ (36/45), the difference between groups was statistically significant(x2=5.075 ,P＜0.05).Conclusion Comprehensive rehabilitation therapy applied in treatment for osteoporotic bulging disc combine diabetes patients can obviously improve the patient's pain symptomsand and the lumbar spine, obtain better treatment effect, worthy of clinical popularization and applications.

Objective: To study the difference in tooth profile among Chinese,Caucasian and Japanese with normal occlusion.Methods: The data of the measurments of Chinese,Caucasian and Japanese with normal occlusion were collected from published studies.Crown angulation,crown inclination and crown convex were used in the comparation among the peoples. Results: Tooth profile in Chinese was significantly different from that of Caucasian but was similar to that of Japanese. Conclusion: The orthodontic appliances should be modified when we use the straight wire appliances that is suitable for Caucasian and Japanese.

Retinitis pigmentosa (RP) is a hereditary disease characterized by the progressive loss of photoreceptor cells. Disease pathology primarily affects rod photoreceptor cells first but light-insensitive cone photoreceptor bodies can survivor longer. Delivered by adeno-associated viral vector or lentiviral vector, expression of microbial-type rhodopsin, channelrhodopsin-2 or archaebacterial halorhodopsin in the survived retinal cells can substitute for the native phototransduction cascade in mouse models of retinitis pigmentosa. It can also restore light sensitivity and activate all retinal cone pathways and drive sophisticated retinal circuit functions. Thus, expression of channelrhodopsins or halorhodopsin might be a potential strategy for the restoration vision of patients with RP.

Objective To investigate the effects of different doses of diphtheria toxin on cochlear structure and auditory function of adult wildtype mice.Methods The auditory-mature wild type C57BL/6J mice 4 weeks old were randomly devided into 50 ng/g group, 100 ng/g group and control group.C57BL/6J mice in the 50 ng/g or 100 ng/g group were injected 50 ng/g or 100 ng/g diphtheria toxin intraperitoneally for one time, respectively, and the control mice were injected equal volume of normal saline for one time.Then we investigated the ABR threshold change and morphological change of inner and outer hair cell and spiral ganglion neuron 7 days after the injection.Results At 7 day post diphtheria toxin injection compared with those of in control group, in the 50 ng/g group, there was no threshold elevation across frequencies(8 kHz ABR threshold was 20.0±3.78 and 20.83±2.04 dB SPL for 50 ng/g and control respectively), and no loss of inner and outer hair cells (for both groups, the HC loss rates were 0.3%~1%) or SGN (the SGN density was 39.45±3.65, 41.03±3.73/105 μm2, in 50 ng/g and control, respectively).However, the 100 ng/g group, compared with those of in control group, the ABR threshold (8 kHz ABR threshold was 63.0±4.47 dB SPL, respectively)was significantly elevated across each frequency(t=19.62,P<0.001), and there was significant loss of outer hair cell (the loss rate of IHC and OHC was 0.5%±0.1%, 10.7%±0.3%, respectively), which was 10% loss in the apical, middle and basal turn(t=42.219,P<0.001).And the loss of spiral ganglion neuron (the SGN density was 25.55±3.66/105 μm2) was 38%, which was significantly different from the control(t=10.985,P<0.001).Conclusion High dose injection of diphtheria toxin can cause loss of outer hair cell and spiral ganglion neuron in wild type auditory-mature C57BL/6J mice.

Objectives To explore the perceived stigma among family members of people with schizophrenia and to identify the influential factors related to perceived stigma in socio-demographic characters of family members and patient characters.Methods Total 127 family members of people with schizophrenia in a psychiatric hospital in Beijing were surveyed by the Perceived Devaluation-Discrimination Scale developed by Link.Results The mean score of the perceived devaluation-discrimination scale is 2.60±0.44.It was significantly higher than the 2.5 midpoint(t=2.53,P<0.05).Family member's perceived stigma was significantly different between different groups of residence area,education level,occupation and family income (P<0.05).Perceived stigma were not affected by patient characters (P>0.05).Family members'education level was the influencing factors of stigma,and the R~2 Square is 0.213.Conclusions The family members of people with schizophrenia suffered from high stigma.Education level of family member may be one of the influential factors.

Objective:To explore the feasibility of mesencephalon progenitor cells as dopamine neuron's graft in treatment of Parkinson disease(PD) in rats. Methods: Animal model of PD were established in SD rats by 6 hydroxydopamine. Mesencephalon progenitor cells were obtained from 13 day old fetal rats. After in vitro proliferation and differentiation, the cells were planted into PD rat striatum. Results: Progenitor cells were expanded in an undifferentiated state with endothelia growth factor and basic fibroblast growth factor as mitogens. IL 1 and striatal culture media further increased the number of TH immunoreactive cells. Transplantation of these neurons relieved the rotation symptom of PD rats. Conclusion: Transplantation of mesencephalon progenitor cells has certain effects on PD rats.

The variable heavy chain region (VH) genes of 3 untreated patients with B-cell chronic lymphocytic leukemia (B-CLL) were cloned and analyzed. The VH family used was VH3-11, VH3-72 and VH3-33. More than 2% difference from the corresponding germline gene was detected in all the 3 obtained potential functional genes (average 16.7). Mutation pattern analysis indicated evidence of antigen selective pressure observed in 1 of 3 cases. Our findings suggested that the tumor cells originate from post-GC cells.
