Objective To observe the effect of Zhi Qing Capsule on the plaque formation of hyperlipemia rabbits and to discuss its mechanism.Methods Forty-eight New-Zealand rabbits were randomly divided into normal control group,hyperlipemia group,Xuezhikang control group and three Zhi Qing capsule groups.Before and after 2-week treatment,the serum levels of total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C) and high density lipoprotein cholesterol(HDL-C) in the serum were determined.After 4-week treatment,TC and TG contents in the liver,and nitric oxide(NO),thromboxan B2(TXB2) and endothelin-1(ET-1) levels in the serum were measured.At the end of the sixth week,all rabbits were killed to observe aorta pathological changes.Results Zhi Qing Capsule can obviously counteract the increase of serum TC,LDL-C and liver TC in the hyperlipemia rabbits,restrain the formation of aorta atherosclerotic plaques,increase the level of NO and decrease the levels of TXB2 and ET-1.Conclusion Zhi Qing Capsule has an evident effect on resisting the lipid metabolism disturbance and atherosclerosis.

Objective To explore the effect on effect of combined use of Y27632 (ROCK II inhibitor)and TDZD-8(GSK-3β inhibitor)on axonal regeneration of dorsal root ganglion (DRG) neurons in neogenetic rats. Methods All the thoracolumbar DRGs of two neogenetic Sprague-Dawley (SD)rats(<5 days)were harvested under the stereopsis raicrostat,and then the DRG neurons were cultured,purified and indentified.Fifteen adult female SD rats were randomly divided into three groups,ie,complete paraplegia group(5 rats),sham operation control group(5 rats)and normal group(5 rats)respectively.The T8-10 spinal cord extracts (SCEs) were harvested in the complete paraplegia group,sham operation control group and normal group respectively at day 7 after spinal cord injury.The experiment was divided into group A(DRG neurons + PBS),group B(DRG neurons + complete paralysis SCE),group C(DRG neurons + complete paralysis SCE + different concentration Y27632),group D(DRG neurons + complete paralysis SCE + different concentration TDZD-8)and group E(DRG neurons + complete paralysis SCE + proper concentration Y27632 and TDZD-8).The average axonal length and expression intensity of Tubulin βⅢ at distal end of neuronal axons were observed after two days of co-culture respectively in intro. Results (1)The average axonal length and expression intensity of Tubulin βⅢ at axon shaft and growth cone in the group B were significantly shorter and weaker than that in the group A,with statistical difference.(2)In the group C,the average axonal length and expression intensity of Tubulln βⅢ at axon shaft and growth cone in 5-10 μmol/L Y27632 treatment groups were more than that in the group B but lower than that in the group A.The average axonal length and expression intensity of Tubuhn βⅢ at axon shaft and growth cone in 20-50 μmol/L Y27632 treatment group were longer and stronger than that in the group A and the group B,especially the group B.Among different concentration Y27632 treatment groups,there was a longest average axonal length and strongest expression intensity of Tubulin βⅢ in 30 μmol/L treatment group.(3) In the group D,there was a longer average axonal length in 0.5-3 μmol/L TDZD-8 treatment group than that in the group A and the group B,with the longeat average axonal length in l μmool/L TDZD-8 treatment group.In 5-25 μmol/L TDZD-8 treatment groups,the average axonal length showed no difference compared with the group B but wns shorter than that in the group A.In all different concentration TDZD-8 treatment groups,the expression intensity of Tubulin βⅢ at axon shaft and growth cone was significantly stronger than that in the groups A and B.(4) In the group E,although the average axonal length was increased in the group E,there was no statisilcal difference compared with the group A,30 μmol/L Y27632 treatment group and l μmol/L TDZD-8treatment group.There was a significantly longer average axonal length in the group E than it in the group B and the expression intensity of Tubulin βⅢ at axon shaft and growth cone was stronger in the group E compared to the group A,30 μmol/L Y27632 treatment group and l μmol/L TDZD-8 treatment group.Conclusion The complete paralysis SCEs obviously inhibits DRG axonal growth,induces axonal retraction and growth cone collapse.High concentration of Y27632 can more obviously promote the axon growth compared with the low concentration,while the low concentration of TDZD-8 can obviously promote the axon growth.Combined use of appropriate concentration of TDZD-8 and Y27632 can promote the axon growth and induce the axons branching,as facilitates the formation of the axon circuit.

Objective To study the clinical feature, diagnossis and therapy of open spinal cord injury. Methods A retrospective study was performed in 15 patients with open spinal cord injury including 14 males and one female, at age range of 15-46 years (mean 23 years). There were two patients with open cervical spinal cord injury, 11 with open thoracic spinal cord injury and two with open lumbar spinal cord injury. Injury causes included sharp knife injury in 12 patients, firearm injury in two and stick stabbing in one. According to ASIA scale, there was one patient at Grade A, two at Grade B, seven at Grade C, four at Grade D and one at Grade E preoperatively. Foreign bodies were found in the wound in four patients. There were three patients combined with spinous process fracture, eight with vertebral plate fracture and five with vertebral body fractures. All 15 patients were treated by emergency management including vertical canal exploration, hematoma debridement or foreign body removal. Results Postoperative complications included cerebrospinal fluid leakage in two patients and wound infection ( without spinal cord infection) in one. There were different degrees of neural functional recovery in five patients. The post-operation ASIA scale: one patient at Grade A, three at Grade C, 10 at Grade D and one at Grade E,with no patient at Grade B. Conclusions For open spinal cord injury, emergency operation is necessary under adequate preoperative preparation. Preoperative identification of foreign bodies, exploration and decompression are beneficial to spinal cord function recovery and reduction of the incidence rate of postoperative complications like infection or hemorrhage.

Objective To observe the effects of Huazhuo Granule on expression of phosphatidylinositol-3-kinase (PI-3K) and glucose transporter 4 (GLUT4) in skeletal muscle type 2 diabetes (T2DM) rats;To discuss its effects on activating signal path of PI-3K and GLUT4. Methods High-fat diet combined with low-dose streptozotocin intraperitoneal injection was used to establish T2DM rat models. The rats were randomly divided into blank group, Huazhuo Granule group, rosiglitazone group, and model group. Each treatment group was given relevant medicine for gavage. Model group and blank control group were given normal saline for gavage. The general state, weight, and food ration of rats were observed. After ten-week medicine intervention, 10%chloral hydrate was used for anesthesia to detect the levels of FBG, OGTT (2 h PG), and FINS. RT-PCR was used to detect the expressions of PI-3K and GLUT4 mRNA of rat skeletal muscle in all groups. Results Compared with model group, the levels of FBG, 2 h PG, and FINS decreased (P<0.05);the expressions of PI-3K and GLUT4 mRNA of rat skeletal muscle increased significantly (P<0.05). Conclusion Huazhuo Granule has the effects on increasing insulin sensitivity, which is related to activating insulin signal path of PI-3K and GLUT4 of skeletal muscle tissues.

OBJECTIVE:To investigate clinical efficacy and safety of tiopronin combined with lamivudine in the treatment of pulmonary tuberculosis complicated with chronic hepatitis B. METHODS:150 cases diagnosed as pulmonary tuberculosis with chronic hepatitis B were randomly divided into group A(drug combination group),group B(lamivudine group)and the group C (control group),with 50 cases in each group. 3 groups were given isoniazid+rifapentine+ethambutol+levofloxacin(2HTELfx/4HT) anti-TB treatment and liver protection treatment,etc. Group B was additionally given Lamivudine tablet orally,0.1 g,qd;group A was additionally given Tiopronin tablet 0.3 g,tid,on the basis of group B. The treatment course of 3 groups lasted for 6 months. Liver damage,serum fibrosis indexes of 3 groups were observed in 3 groups before and after treatment as well as hepatitis B virolo-gy indexes,clinical efficacy and the occurrence of ADR after treatment. RESULTS:After treatment,serum levels of ALT,AST and TBIL weresignificantly increased in group C,significantly decreased in group A,with statistical significance(P<0.05).There was no statistical significance in above indexes of group B before and after treatment(P>0.05). Serum levels of ALT,AST and TBIL after the treatment:group A0.05). Serum fibrosis indexes of group A and B decreased significantly compared to before treatment,with statistical significance (P<0.05);serum fibrosis indexes after the treatment:group A0.05). CONCLUSIONS:Tiopronin combined with lamivudine can significantly reduce liver function damage caused by an-ti-TB drugs. It is conducive to the smooth progress of tuberculosis chemotherapy with fewer adverse reactions.

Objective To summarize the efficacy of cervical pedicle screw fixation in the treatment of cervical spinal cord injury without fracture and dislocation.Methods From September 2007 to March 2010,21 patients with cervical spinal cord injury without fracture and dislocation combined with developmental cervical stenosis were managed by pedicle screw fixation in unstable segments,and then single open-door laminoplasty in stenosis segments.The clinical outcomes were reviewed and summarized.Results All the patients received follow-up of 1-3 years.Two patients had superficial wound infection,which was cured by dressing change.One presented intra-incisional hematoma one week post-operatively and was cured by hemostasis and drainage.One had door-reclosing without symptom aggravation.There was neither perforation of pedicle screws nor breakage,loosening or displacement of internal fixation.The curvature of cervical lordosis at follow-up had significant rectification in comparison with that at preoperation,but showed unobvious change as compared with that immediately after operation.According to the modified Japanese Orthopedic Association (JOA) score,the neurological score improved from preoperative 4-15 points to 9-17 points at the final follow-up,which revealed more than 80％ of recovery in 13 patients,50％ -80％ of recovery in six and 5％ -50％ of recovery in two,with the average recovery rate of 75％.Conclusion For unstable segments in patients with cervical spinal cord injury without fracture and dislocation combined with developmental spinal stenosis,posterior pedicle screw fixation can avoid the risk of further spinal cord injury in single open-door laminoplasty and restore the physiological curvature of cervical vertebrae,which provides solid foundation for backward drift of spinal cord and creates favorable condition for recovery of spinal cord function.

Blepharospasm is a focal dystonia of the orbicularis oculi muscles, producing excessive eye closure. The etiology and pathogenesis is still unclear now. lt is usually appearing in adult period and predominant in females. The symptoms are typically triggered by stress, fatigue, intense light or individual factors. At advanced stages patients develop functional blindness. At present the main treatments include: botulinum toxin ( BTX ) , surgical procedures, systemic and ocular drugs and traditional Chinese medicine treatment. BTX administration has been an effective treatment. Surgical procedures have good effect but should be limited to the rare patients that do not respond to botulinum toxin treatment. A great variety of drugs have poor results. Chinese medicine has a certain therapeutic effect. Transcranial magnetic stimulation can improve symptoms. The epidemiology, anatomy, physiology, clinical manifestations, differential diagnosis, pathogenesis and treatment system were reviewed in this paper.

OBJECTIVETo compare differences of clinical therapeutic effect of heat-sensitive moxibustion with different doses for irritable bowel syndrome (IBS).

METHODSSixty cases of IBS were randomly divided into a saturated-dose group (30 cases) and a traditional-dose group (30 cases). Heat-sensitive moxibustion was applied in both groups. The acupoints that had the strongest heat-sensitive feeling were selected and treated by warm and suspended moxibustion with moxa stick. Disappearance of heat-sensitive feeling was taken as the sign of treatment time in the saturated-dose group, while the traditional-dose group was treated for 15 min each time. The treatment in both groups was given twice a day for first 5 days, and from the sixth day it was given once a day for continuous 25 times, totally 30 days. Clinical symptom scores and therapeutic effect before and after treatment in two groups were observed.

RESULTSAfter the treatment, the cured and markedly effective rate was 75.0% (21/28) in the saturated-dose group, which was inferior to 44.4% (12/27) in the traditional-dose group (P < 0.05). The clinical symptom scores, including diarrhea, abdominal distension and pain, were obviously reduced in two groups compared with those before the treatment (all P < 0.05). Compared with the traditional-dose group, the symptom scores of diarrhea and abdominal distension in the saturated-dose group were obviously decreased (0.87 +/- 0.13 vs 1.27 +/- 0.21, P < 0.01; 1.12 +/- 0.41 vs 1.32 +/- 0.26, P < 0.05).

CONCLUSIONThe moxibustion featured with disappearance of heat-sensitive feeling and saturated dose has better therapeutic effect than that with traditional-dose for treatment of IBS. As individual dynamic amount of moxibustion, disappearance of heat-sensitive and quantitation varies from person to person, which is one of the key factors to obtain the best curative effect.
