ObjectiveTo explore pathogenesis of headache after subarachnoid hemorrhage (SAH) whether related with immune inflammatory reaction in subarachnoid and observe the effect of immunosuppressive action of dexamethasone on headache.Methods80 patients who was consciousness and complained headache after SAH were randomly divided into four groups, treated only with mannitol, mannitol plus cerebrospinal fluid (CSF) replacement, intrathecal and vein injection with dexamethasone. Effects of four groups were observed.ResultsEfficiencies of four groups were respectively the mannitol group 27.27%, the permutation group 66.67%, the intrathecal group 92.36% and the vein group 30.00%. There was a significantly difference between the intrathecal group and other three groups, and the time of headache remission for intrathecal group was also longer than that of other three groups (P<0.01).ConclusionThe wide immune inflammatory responses in subarachnoid induced by degenerative and hemic CSF is likely main cause of headache after SAH and intrathecal injection with dexamethasone has an obviously effect.

OBJECTIVE:To evaluate the association between UGT1A1 gene polymorphism and irinotecan-induced 3-4 degree neutropenia,and to provide evidenced-based reference for clinical treatment. METHODS:Retrieved from CJFD,Wanfang data-base,VIP,PubMed,EMBase,Science direct and Cochrane library,related studies about UGT1A1*28 and UGT1A1*6 gene polymorphism and irinotecan-induced 3-4 degree neutropenia were collected. After data extraction and quality evaluation of included studies,Meta-analysis was conducted by using Review Man 5.3 software. RESULTS:A total of 29 studies were included,involv-ing 2408 patients. UGT1A1*28 includ wild genotype TA 6/6(UGT1A1*1/*1)and mutations genotype TA 6/7(UGT1A1*1/*28)、TA 7/7(UGT1A1*28/*28),UGT1A1*6 includ wild genotype GG and mutations genotype GA、AA. Results of Meta-analysis showed:the incidence of 3-4 degree neutropenia in UGT1A1*28 and UGT1A1*6 mutations genotype were significantly higher than wild genotype,with statistical significance [UGT1A1*28:OR=1.92,95%CI(1.52,2.44),P<0.001;UGT1A1*6:OR=2.49, 95%CI(1.46,4.26),P<0.001]. Using medium-dose and high-dose of irinotecan,the incidence of 3-4 degree neutropenia in UGT1A1*28 and UGT1A1*6 mutations genotype were significantly higher than wild genotype,with statistical significance [UGT1A1*28:OR=2.06,95%CI(1.57,2.70),P<0.001);UGT1A1*6:OR=1.92,95%CI(1.35,2.74),P<0.001]. Using low-dose of irinotecan,there was no statistical significance in the incidence of 3-4 degree neutropenia between UGT1A1*28,UGT1A1*6 mutations genotype and wild genotype [UGT1A1*28:OR=1.20,95%CI(0.70,2.08),P=0.51;UGT1A1*6:OR=3.19,95%CI (0.85,11.89),P=0.08]. CONCLUSIONS:Using medium-dose and high-dose of irinotecan,UGT1A1*28 and UGT1A1*6 muta-tions will increase the risk of severe neutropenia in cancer patients. Using low-dose of irinotecan,there is no clear correlation be-tween gene polymorphism and the neutropenia.

Objective: In order to study how to accelerate the reconstitution immunofunction in BMT mice, first of all, we established a immunodeficiency model of BMT in BALB/C mice. Then BMT mice were injected with PCD-hIL-2 directly into skeletal muscle, and treated with traditional Chinese medicine. Methods: The experiment groups are designed as（A）Chinese medicine + PCD-hIL-2;（B）PCD-hIL-2;（C）Chinese medicine +hIL-2;（D）Chinese medicine;（E）hIL-2;（F）BMT;（G）normal control;（H）radiation control. Results: We compared groups A B C D to E or F groups, found（1）The splenocytes/thymocytes count increase obviously.（2）Killing activity of NK cell rises obviously in vivo.（3）The response of splenocytes、thymocytes、BM cells to mitogen goes up.（4）The reactivity of splenocytes to foreign IL-2 goes up. （5）CFU-GM count is increased. Conclusion: The expression of hIL-2 is very low by nude DNA injection ,but it is enough to have biological function and therapeutic effect .If only Chinese medicine was applied, the immunological condition was obviously recovered.

Objective To evaluate the effects and safety of uterine artery embolization for uterine leiomyoma. Methods Total of 185 patients with uterine leiomyoma were treated by UAE. They were followed for one to 6 years to observe the changes of leiomyoma size and improvement in clinical symptoms. Ovarian function was evaluated in 44 cases. Results Bilateral embolization of uterine arteries was performed in 185 patients. Follow-up of 1 ～6 years for 292 leiomyoma indicated that one to 9 months after embolization, shrinkage of leiomyoma size was the most significant factor. One year after embolization, leiomyoma sizes decreased a little. Shrinkage of submucous leiomyoma was more significant than that of intratumoral one, and the latter was more significant than subserous one. Shrinkage of leiomyoma with large size ( volume ≥ 150cm~3) was less than that of small one. Menorrhagia, anemia and pressure symptoms were all resolved. There was no significant difference between pre- and post embolization ovarian hormone level. Conclusions The significant reduction in leiomyoma volume and resolution of clinical symptoms confirmed that the treatment validity of symptomatic leiomyomas by UAE. UAE is an effective therapeutic procedure which has no adverse effect on the ovarian function.

Objective To investigate effect of arthroscopic ankle arthrodesis in the treatment of endstage post-traumatic ankle arthritis.Methods Between July 2007 and December 2010,21 patients with post-traumatic ankle arthritis underwent arthroscopic arthrodesis in our hospital.There were 14 males and 7 females,aged from 21 to 68 years (average,37 years).Before operation,conservative treatments were unsuccessful in all patients.During operation,the articular cartilage was removed completely,and then micro-fracture was made in bone near articular surface.Then,the operating ankle were reduced and fixed provisionally with Kirschner wires.A C-arm X-ray system was used to confirm the reduction of operating ankle,and the operating ankle was fixed with cannulate screws if the reduction was satisfactory.Two patients also underwent arthroscopic subtalar arthrodesis.After operation,the affected ankle was fixed with plaster for six weeks.Then partial weight-bearing were allowed and gradually increased until bone union.Results All patients were followed up for 1 to 4 years (average,1.8 years).All affected ankle achieved bone union after 10 to 16 weeks (average,12 weeks).No early complications occurred,such as poor wound healing and infection.Subtalar arthritis with pain occurred in 3 patients; the symptom relieved in 2 of them after conservative treatment and in 1 patient after subtalar arthrodesis.The VAS score improved from preoperative 8.1±1.5 to 2.7± 1.1 one year postoperatively,which showed statistical significance (t=3.153,P=0.005).Conclusion Arthroscopic ankle arthrodesis provides an alternative method for treating end-stage post-traumatic ankle arthritis,which has some advantages,such as less surgical trauma,more beautiful incision and higher fusion rate.However,it needs special equipments and a learning curve.

Objective:To study the function of transcription factor 4 (TCF4) and to prepare TCF4 polyclonal antibody.Methods:pET-41/TCF4 was transformed into E.coli BL21(DE3) and induced by IPTG.The purified GST-TCF4 fusion protein was applied to immunize rabbit to produce antiserum. The specificity of the affinity of purified anti-TCF4 antibody was examined by Western blotting analysis of the eukaryotic expressed products of TCF4. Dig-labeled probe and antibody against TCF4 were used to examine the expression of TCF4 in Saos-2 cells under mechanical stretch. Results:Western blotting showed that the antibody could bind to TCF4 specifically. The expression of TCF4 mRNA and protein were significantly increased in Saos-2 cells under mechanical stretch. Conclusion: TCF4 antibody has been prepared successfully.

Objective To explore the protective effect of treatment of somatostatin combined with growth hormone on brain injury in early severe acute pancreatitis(SAP)rats, and to investigate the relationship between brain injury and ratio of endothelin 1(ET 1) /nitric oxide(NO). Methods SAP model was established by retrograde pancreatic bile duct injection of 3.5% sodium taurocholate at a dose of 2.5 ml/kg in rats. Eighty SAP rats were equally divided into SAP group, somatostatin (S) group (introvenous injection of somatostatin at a dose of 42 ?g/kg once a day for 2 days), somatotropin (G) group (subcutaneous injection of somatotropin at a dose of 0.5 ?g/kg once a day for 2 days) and S+G group. Twenty normal rats were used as controls. The changes of encephaledema and blood brain barrier permeability were measured by dry wet method and Evan′s blue staining, respectively. Apoptosis of brain cells was detected by TUNEL method, and the ratio of serum ET 1/NO was also determined. Results The ratio of serum ET 1/NO was remarkably increased in SAP rats, which was correlated with the intensity of brain edema, permeability of blood brain barrier and apoptosis of brain cells. The treatment of somatostatin combined with growth hormone reduced the ratio of ET 1/NO and thus decreased the intensity of encephaledema, the permeability of blood brain barrier and apoptosis of brain cells. The changes of the brain slow wave were found simultaneously by electroencephalography in SAP rats after the therapy. Conclusions The treatment of somatostatin combined with growth hormone in SAP rats can inhibit serum ET 1/NO, prevent the development of brain edema, decrease the permeability of blood brain barrier, and alleviate the brain cells apoptosis. All these result in the relief of the brain injury.
