Objective To explore the clinical application value of blood routine examination in judgment of the activity of inflammatory bowel diseases.Methods 102 patients with inflammatory bowel disease were selected as the main research objects,60 healthy persons in the same period were selected as the control group,all of the subjects were received routine testing of blood,C-reactive protein and erythrocyte sedimentation rate,and the relationships between disease and blood routine indexes were compared.Results In UC group,the PLT,WBC RDW index levels of remission were higher than those of the control group,the differences were statistically significant(t =6.75,8.21,5.73,all P ＜0.05).In patients with UC,the HGB,HCTand MPV index levels were lower than those in the remission patients and the control group,the differences were statistically significant(t =8.12,11.03,6.72,9.35,10.23,8.71,all P ＜0.05).But the PLT index was higher than that of patients in remission,the RDW and WBC indexes were higher than those in the control group and the remission period,there were statistically significant differences (t =7.59,8.51,6.03,all P ＜ 0.05).The routine blood indexes of the relief patients of CD group had significant differences compared with the control group(t =6.17,7.29,9.01,10.35,8.27,7.69,8.01,9.91,allP ＜ 0.05),the HCT,MCV,HGB and MPV indexes were lower than those of the control group,the differences were statistically significant (t =9.01,10.35,8.27,9.9i,all P ＜ 0.05),the WBC,PLT,N and RDW indexes were higher than those of the control group,the differences were statistically significant (t =6.17,7.29,7.69,8.01,all P ＜ 0.05).In UC group,the HGB,HCT,MCV and MPV indexes were lower than those in the remission patients and the control group,there were statistically significant differences(t =8.19,6.97,7.53,9.02,all P ＜ 0.05).But the PLT,RDW,WBC and N indexes were higher than those in the remission patients and the control group,the differences were statistically significant (t =9.81,7.94,8.36,7.61,P ＜ 0.05).In the active patients of CD group,the WBC and N indexes were significantly higher than those of UC group,the differences were statistically significant (t =8.15,9.07,all P ＜ 0.05).In the remission patients of CD group,the PLT index was significandy higher than that in the remission patients of UC group,the difference was statistically significant (t =10.35,P ＜ 0.05).Conclusion Indexes of blood routine has obvious significance in activity of inflammatory bowel disease,and it is significant correlation with inflammation index,which can be used as one of the routine clinical method to determine the activity of inflammatory bowel diseases.

Aim To investigate the protective effect and the underline mechanisms of total flavonoids from Sorbus Tianschanica L leaf (TFST) against myocardial ischemia/reperfusion (I/R) injury.Methods The I/R injury model of rat isolated heart was prepared by improved Langendorff retrograde perfusion method.Following the treatment,the coronary blood flow levels (CF),left ventricular developed pressure (LVDP) and maximal rise/fall rate of left ventricular pressure (±dp/dt_(max)) were monitored as the myocardial function.The superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in myocardial tissue were measured by the commercial kits. The in vitro anti-oxidative capacity of TFST was detected by the DPPH and lipid peroxidation reaction system.Results Compared with I/R injury group, pre-incubation with TFST (6.0 mg·L~(-1)) significantly improved the LVDP,±dp/dt_(max) and CF during reperfusion. TFST (6.0 mg·L~(-1)) treatment significantly increased the SOD activities and reduced the MDA levels in myocardium tissue.Moreover,TFST (from 6.25 to 100.0 mg·L~(-1)) scavenged the DPPH, hydroxyl radical and superoxide anion free radicals, and inhibited the lipid peroxidation reaction in a concentration-dependent way.Conclusions All the results demonstrate that TFST possesses the cardioprotective effect on ischemia/reperfusion injury.This efficacy may be due to its antioxidative activity.

Keratoconus(KC)is a disease characterized by limited corneal cone-like protrusions accompanied by thinning of the corneal stroma in the area of protrusion, which commonly occurs before and after puberty, manifests itself bilaterally, and is a potentially blinding ophthalmic disease. It is a potentially blinding eye disease. Studies have shown that its pathogenesis is related to environmental factors, inflammatory response, immune function, and mechanical stimulation, but the mechanism of the occurrence and progression of KC has not yet been conclusively determined. A variety of genes, represented by corneal remodeling-related genes, have been found to have some influence on the development of cone cornea. More studies are still digging into the genetic targets associated with the development of cone cornea. This article reviews the targets and influence of genes in the pathogenesis of cone cornea, to explore the application value of genes in the early diagnosis and intervention of cone cornea, and to provide new ideas for future research on the pathogenesis of cone cornea.

OBJECTIVE：To study the improvement effect and possible mechanism of Leontopodium leontopodioides combined with Astragalus membranaceus on the renal function of mesangial proliferative glomerulonephritis （MsPGN） model rats. METHODS：Totally 85 rats were randomly divided into sham operation group （n＝10）and modeling group （n＝75）. Sham operation group underwent sham operation ，and MsPGN model was induced by immunological method [Freund ’s adjuvant+BSA + lipopolysaccharide（LPS）] in modeling group. After successfully modeling ，70 rats were randomly divided into model group ，L. leontopodioides+A. membranaceus high-dose，medium-dose and low-dose groups （4.05，2.03，1.02 g/kg，by total crude drug ），L. leontopodioides alone group （2.70 g/kg，by crude drug ），Tripterygium glycosides tablet group （positive control 1，0.02 g/kg）， Lotensin tablet group （positive control 2，0.02 g/kg），with 10 rats in each group. Sham operation group and model group were given constant volume of normal saline intragastrically ； administration groups were given relevant drug solution intrasgastrcially at a volume of 15 mL/kg，once a day ，for consecutive 5 weeks. At last administration ，24 h urinary lnzyxyqy2003@163.com protein，urine creatinine and serum creatinine were determined in rats. The right kidney was weighed ，and HE staining was used to observe the pathomorpholog y changes of renal tissue. Immunohistochemistry was used to detect the protein expression of NF-κB p65 in renal tissue. Western blotting assay was used to determine the protein expressions of NF-κB p65，IκBα，ERK，p-ERK and p 38 MAPK in renal tissue. RESULTS ：Compared with sham operation group ，right kidney weight ，24 h urine protein and serum creatinine levels ，protein expressions of NF-κB p65， p-ERK and p 38 MAPK in renal tissue were increased significantly in model group （P＜0.05 or P＜0.01）；the level of urine creatinine and protein expression of IκBα in renal tissue were decreased significantly（P＜0.05 or P＜0.01）；there were obvious glomerular hypertrophy ，diffuse increase of mesangial cells ，necrosis of renal tubules and other pathomorphological changes in renal tissue. Compared with model group ，right kidney weight and serum creatinine level were decreased significantly in L. leontopodioides alone group （P＜0.05），while urine creatinine level was increased significantly （P＜0.05），but there was no statistical significance in the level of 24 h urine protein （P＞0.05）；the right kidney weight ，24 h urine protein ，serum creatinine level and protein expression levels of NF-κB p65，p-ERK and p38 MAPK in renal tissue were decreased significantly in L. leontopodioides+A. membranaceus high-dose group （P＜0.05），while the urine creatinine level and protein expression level of IκBα in renal tissue were increased significantly （P＜0.05 or P＜0.01）；there was no statistical significance in above indexes in L. leontopodioides+A. membranaceus medium-dose，low-dose groups （P＞0.05）；pathological changes of renal tissue were improved to different extents in administration groups ，especially in L. leontopodioides +A. membranaceus high-dose group. CONCLUSIONS ： High dose of L. leontopodioides +A. membranaceus can improve renal function of MsPGN model rats by inhibiting MAPK/NF-κB signal pathway.

OBJECTIVE To study the impr ovement effects of Dianxianqing granule on blood-brain barrier （BBB）injury in Alzheimer’s disease （AD）model mice by regulating NLR family pyrin domain containing 3（NLRP3）inflammasome signaling pathway. METHODS Totally 125 mice were randomly divided into sham operation group （n＝25）and modeling group （n＝100） by body weight. AD model was induced by intracerebroventricular injection of β-amyloid 25-35 in model group. Sham operation group was given normal saline with same method.
