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.

Felty syndrome is a rare disorder that involves rheumatoid arthritis,a swollen spleen,de-creased white blood cell count,and repeated infections.This article analyze the clinical characters of this disease.

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.

A mutation is predominant in weak D individuals,and DⅥⅢ mutation in partial D individuals.

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.

Functional gastrointestinal disease is a group of clinical syndrome of non-organic disease. Its various clinical symptoms have a certain specificity and overlap phenomenon, and the mechanism is not clear. TCM believes thatphychological factorsare an important cause. Emotion failurecan effect spleen and stomach functionthrough liver and heart directly or indirectly.At present, the phychological factors and the relationship between functional gastrointestinal disease are getting attentiongradually. It is recognized that the mechanism of phychological factorsmay be related to brain axis dysfunction, mast cell activation, intestinal flora and so on. This article expounded the above-mentioned mechanism and reviewed the detailed TCM intervention measures to functional gastrointestinal disease in recent years.

It is recommended that cyclophosphamide combined with corticosteroids should be used as the first-line treatment of ANCA ( antineutrophil cytoplasmic antibody) associated with systemic vasculitis ( AASV) , however, cyclophosphamide has notable ad-verse reaction of causing pulmonary fibrosis ( PF) . In this paper, whether cyclophosphamide should be used in an AASF patient with PF was analyzed in order to decide whether AASV with PF is one of contraindications of cyclophosphamide in clinical practice.

Irritable bowel syndrome( IBS)is a common functional gastrointestinal disease,relevant investigations on pathogenesis of IBS mainly focus on genetic susceptibility, social psychological stress, visceral hypersensitivity, dysregulation of brain-gut axis,dysbiosis of intestinal flora,and dysimmunity of intestinal mucosa. This article reviewed the correlation between dysbiosis of intestinal microbiota and dysregulation of brain-gut axis in IBS.

Objective To analyze the vascular architecture characteristics of the complex direct cavernous arteriovenous fistula (cd-CAVF) and to discuss its treatment and the curative effect of interventional embolization. Methods The hospitalization records, imaging features and operation records of 12 patients with cd-CAVF were retrospectively analyzed. Results In the 12 patients with cd-CAVF, the lesion’s blood supply arteries included internal carotid artery (ICA,n=8), primary trigeminal artery (PTA,n=1), middle cerebral artery (MMA,n=2) and basilar artery (BA,n=1). Different degrees of “arterial steal” phenomenon could be observed in all patients. The drainage routes included the superior ophthalmic vein and the inferior petrosal sinus (n=10), and cortical vein (n=2). Interventional embolization was carried out via ICA (n=4), through both ICA and BA (n=5), through MMA (n=2), or through BA (n=1). For the embolization of the lesion the balloons were used in 8 patients, steel coils were adopted in 2 patients, and balloons together with coils were employed in 2 patients. All the patients were followed up for 3-6 months. After the treatment the clinical symptoms and signs disappeared, and the lesions were completely cured in all patients with no complications. During the follow-up period of (60.2 ±26.8) months no recurrence of CAVF was observed. Conclusion The blood supply of cd-CAVF comes directly from the rupture of the blood vessels surrounding the cavernous sinus wall, the “arterial steal” phenomenon is prone to occur, and the drainage via the superior ophthalmic vein and the inferior petrosal sinus is more often seen. Transarterial balloon embolization is very effective for the treatment of cd-CAVF, and the use of coils together with multi-artery approaches is an effective supplementary method.
