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 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.

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.

Chinese herbal pieces are a key factor to protecting the quality of the clinical efficacy of traditional Chinese medicine (TCM), and it is one of the basic elements of ensuring the quality of TCM and people's usage safety. However, Chinese herbal pieces has massive problem such as adulteration and counterfeit, dyeing and weighting, pesticide residues, heavy metals in excess of the standards, and all the issues are repeated excessive in the clinic treatment. These issues impacted sound development of production, management and use of TCM, but also brings common people hidden trouble for the clinical safety of medication. Protect and improve the quality of the Chinese herbal pieces demand that continue improve quality system, in-depth scientific research, and strengthen self-discipline and other factors. So it is fundamentally to ensure good quality of Chinese herbal pieces with the color, taste and shape by systematic supervision to it from the source, production, management and research, with strengthened implementation and en- forcement of the "3G".

BACKGROUND: With the continuous renewal and development of clinical repair techniques, the intraoperatie blood loss has been greatly reduced in the treatment of intertrochanteric fracture; however, no matter what kind of repair methods should be adopted, there are stil a large amount of perioperative hidden blood loss, however, there are few clinical reports for the reasons and related factors. OBJECTIVE: To study the correlation of perioperative hidden blood loss with gender and internal fixation methods in the surgery of elderly femoral intertrochanteric fractures.METHODS: Total y 121 patients with elderly femoral intertrochanteric fractures who received the treatment at Department of Orthopedics, Nanyang City Center Hospital from March 2010 to June 2013 were divided into two groups according to the condition and treatment wishes of patients, and were respectively treated with dynamic hip screw and proximal femoral anti-rotation intramedul ary nail internal fixation. The preoperative hidden blood loss, postoperative hidden blood loss, the total hidden blood loss, dominant blood loss and total blood loss of patients in these two groups were compared. The multiple linear regression analysis on the correlation of perioperative hidden blood loss with gender and internal fixation methods was conducted. RESULTS AND CONCLUSION: There was no significant difference in the preoperative hidden blood loss between these two groups (P > 0.05). The total blood loss, postoperative hidden blood loss and total hidden blood loss in the proximal femoral anti-rotation intramedul ary nail group were significantly higher than those in the dynamic hip screw group (P < 0.05), and the dominant blood loss was significantly lower than that in the dynamic hip screw group (P <0.05). There were significant differences in the preoperative, postoperative hidden blood loss and total hidden blood loss between males and females (P < 0.05), and above indexes in males were significantly lower than in females. The multiple linear regression analysis showed that gender and internal fixation methods were correlated with hidden blood loss (P < 0.05). These results suggest that the perioperative hidden blood loss in surgery for elderly femoral intertrochanteric fractures is closely related to gender and above indexes in internal fixation methods. The perioperative hidden blood loss of male patients is less than that of female patients, and the patients treated with proximal femoral anti-rotation intramedul ary nail fixation have more hidden blood loss than dynamic hip screw fixation.

BACKGROUND:Static compressure effect between the fracture fragments was generated by fixation itself (tension band wire and screw), but dynamic compression effects were generated during flexion. Mechanical strength and stability of patel ar fracture fixation have obvious advantages. However, there are lacks of quantitative comparative studies on static and dynamic compression effects of these fixation methods.
OBJECTIVE:To observe strength changes and clinical significance of static and dynamic compression using four fixation techniques.
METHODS:Standardized transverse patel ar fracture models were created with fresh cow patel as. The patel as were randomly divided into four groups:fixation was accomplished with modified tension band wiring (wire group);modified tension band with braided cable (cable group);interfragmentary screws (screw group);cannulated screw tension band with wire (cannulated screw group). Before fracture fixation, Fuji pressure-sensitive film was laid among fracture fragments to measure the pressure among fracture fragments after fixation, i.e., static and dynamic compression. Model of each group was measured as fol ows:(1) after fixation, the fixation was removed, and the Fuji pressure-sensitive film was taken out;(2) after fixation, material testing machine was used. Samples underwent a three-point bending test with a 5 000 N load, simulating dynamic compression during knee flexion. Subsequently, Fuji pressure-sensitive film was taken out. Each Fuji pressure-sensitive film was tested using prescale FPD-8010E software. Thus, average pressure among broken bone ends was obtained, and statistical analysis was performed. Static and dynamic compression among broken bone ends was compared in each group.
RESULTS AND CONCLUSION:Average static compression was significantly lower in the wire group than in the cable group, screw group and cannulated screw group (P<0.05). Under 5 000 N load of dynamic compression, similar compression among broken bone ends was visible among wire group and cable group, screw group and cannulated screw group (P>0.05). Dynamic compression was higher than static compression in the wire group (P<0.05). Results verified that compared with modified tension band wire fixation technique, cable or screw could evidently increase static compression among broken bone ends, but simultaneously weaken dynamic compression among broken bone ends.

BACKGROUND:The patients with porcelain-fused-to-metal crowns who do examination of magnetic resonance imaging (MRI) can cause artifacts. In recent years, researching for MRI artifacts of different porcelain-fused-to-metal materials has been some progress, but there are less quantitatively reports on the MRI artifacts of different porcelain-fused-to-metal materials.
OBJECTIVE:To evaluate the artifact sizes shown on fast spin-echo T 2-weighted sequence caused by different kinds of porcelain-fused-to-metal crowns.
METHODS:Forty-eight lower right first molar crown patients who had MRI examination in MRI room were enrol ed. The patients were divided into nickel-chromium al oy group, cobalt-chromium al oy group and titanium crown group. Al patients were examined with fast spin-echo T 2-weighted sequences by means of 1.5 T MRI apparatus. MRI artifacts areas of same sequence on the MRI images of different porcelain-fused-to-metal materials were analyzed with variance test.
RESULTS AND CONCLUSION:Forty-five cases appearing to have high signal samples with clearly curved boundary zone that can be measured were selected, 15 cases for each material. Different artifact sizes were produced on the same sequence of different porcelain-fused-to-metal materials, which were (321.67±33.29) mm in the nickel-chromium al oy group, (263.53±34.95) mm2 in the cobalt-chromium al oy group, and (143.67±31.13) mm2 in the titanium crown group. There were significant differences between groups (P<0.05). The artifact size is smal est for the titanium crown and largest for the nickel-chromium al oy crown.
