Intestinal fibrosis is the complications of inflammatory bowel disease (IBD), intestinal myofibro-blast cells are the key to intestinal fibrosis .Intestinal myofibroblasts and its interaction with inflammatory cells play an im-portant role in IBD-related intestinal fibrosis .

In recent years,the basic research on liver fibrosis has been progressed rapidly.This article briefly reviews the cellular and molecular mechanisms of liver fibrosis,including the origin of myofibroblasts,immune regulation,autophagy,and epigenetic regulation,and introduces several new therapeutic targets.More and more evidences show that successful removal of causes is the most important antifibrotic therapy.At present,although the antifibrotic drugs acting on different targets have been emerging,most of them are still in the early stage of research and development,and well-designed clinical trials are needed to confirm their clinical efficacy.

Objective To observe the effect of electroacupuncture on hand dysfunction after stroke. Methods Forty hemiplegic patients after stroke were selected from a multi-center large-scale trail, belonged to rehabilitation group (n=20) and electroacupuncture group (n=20), who accepted routine rehabilitation and additional electroacupuncture, respectively, for six weeks. They were assessed with Brunnstrom Grade, Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT) and modified Barthel index (MBI) before treatment, two, four and six weeks during treatment, and twelve weeks after treatment. Results There were differences between two groups in scores of FMA, WMFT and total time to complete WMFT twelve weeks after treatment (t>1.900, P<0.05). There was no difference between two groups in scores of MBI and Brunnstrom Grade (t=0.532, Z<1.79, P>0.05), but electroacupuncture group seemed to improve more. Conclusion Elec-troacupuncture may improve the muscle strength for patients in flaccid paralysis, and promote the recovery of hand function for patients af-ter stroke.

In order to solve some limitations and difficulties in guiding the practical work of determination and classification of the areas of high water iodine and the endemic areas of iodine excess goiter (GB/T 19380-2003),we carried out the revision on the original standard from 5 aspects such as the name,normative reference file,the definition and the technical indicators of classification of high iodine areas and the endemic areas of iodine excess goiter,such as sampling method in appendix and so on,and worked out the standard of definition and demarcation of water-borne iodine-excess areas and iodine-excess endemic areas.Enforcement of the new standard will bring important social benefits.

ABSTRACT:Objective To observe the influence of Osthole on cerebral ischemia-reperfusion injury and its acting mechanism.Methods We randomly divided 50 SD rats into sham (Sham)group,ischemia-reperfusion injury (IRI)group and Osthole (25,50,and 100 mg/kg)(Osthole)groups (n=10).The neurological symptoms, extent of cerebral infarction and cerebral water content were evaluated by physical approach.The activities of ROS and ATP were examined by the kit;the mitochondrial membrane potential (MMP ) was measured by flow cytometry.The expressions of Bax,Bcl-2,Caspase3,clevage-Caspase3,Caspase9,clevage-Caspase9,cytoplasmic AIF and cytochrome C were measured by Western blotting.Results Compared with those in sham group,the extent of cerebral infarction and cerebral water content,changes of neurological symptoms,activities of ROS,and expressions of clevage-Caspase3 ,clevage-Caspase9 ,Bax,cytoplasmic AIF and cytochrome C in IRI group were significantly increased (P<0.05).However,the activities of ATP,expressions of Caspase3,Caspase9,Bcl-2 and MMP,and ATP activity were decreased (P<0.05).Compared with those in IRI group,the extent of cerebral infarction and cerebral water content,changes of neurological symptoms,activities of ROS,and expressions of clevage-Caspase3 ,clevage-Caspase9 ,Bax,cytoplasmic AIF and cytochrome C in Osthole group were significantly decreased (P<0.05).But the activities of ATP,expressions of Caspase3,Caspase9,Bcl-2 and MMP,and ATP activities were increased (P < 0.05 ). Conclusion Osthole pretreatment can attenuate cerebral ischemia-reperfusion injury,which is associated with suppressing mitochondria-mediated apoptosis.

Objective To study the change of pancreatic microcirculation in the early phase of acute pancreatitis. Methods Literatures on acute pancreatitis and microcirculation were collected and reviewed.Results Pancreatic microcirculation has changed in the early phase of acute pancreatitis, including contraction of interlobular arteriole, slowing of blood fluid, increasing of pancreatic vascular permeability, leukocyte adherence in postcapillary venules, and decreasing of pancreatic perfusion.Conclusion Impairment of pancreatic microcirculation in the early phase of acute pancreatitis may play a key role in the progression of this disease.

Spinal cord injury occurs with an average annual incidence of 15 40 cases per million of population. The costs of treatment and rehabilitation in the living period of patients with spinal cord injury are very high. Prevention, therapy and rehabilitation of spinal cord injury have become a major subject in medical science. The aim of this article is to summarize the statistics of incidence, etiological factors, clinical characteristics and complications in patients with spinal cord injury.

Platelet-rich plasma(PRP) is a highly-concentrated plasma enriched in platelets and various growth factors. These growth factors will be released abundantly by platelets when PRP is activated by thrombin, which plays a key role in accelerating wound healing, bone repair, and meanwhile, in controlling of inflammatory process. Biocompatibility and versatility of PRP have been confirmed in clinical studies as well as its excellent effects on tissue reparation. These have lead to the extensive use of PRP in many medical fields as a therapeutic alternative. Mechanism of PRP in bone and tissue repair the application of PRP in the field of orthopedics is reviewed in this article. In addition, attempt is made to discuss about some problems still existing in the clinical application of PRP.

Brucellosis is a zoonosis with worldwide distribution.There is an upward trend in the incidence of this disease in recent years,and multiple systems and organs are affected.Complication of bone and joint is the most commonly seen of Brucellosis.Although cardiovascular complication is rare,it is the major reason for Brucellosis-related mortality.The author summarized domestic and foreign studies on Brucella endocarditis.

Objective To investigate the changes in serum leptin and adiponectin levels and their significance in patients with chronic hepa-titis B virus (HBV)infection.Methods One hundred and twenty -five patients with chronic HBV infection (44 HBeAg -positive cases, 31 HBeAg -negative cases of chronic hepatitis B,23 chronic HBV carriers,and 27 inactive HBsAg carriers)were recruited in the present study.Fifty -five healthy people served as the control group.Blood samples were collected at 8 to 9 AMof the next morning after overnight fasting.Blood glucose,blood lipids,renal and liver function parameters,fasting insulin,serum HBV markers,and HBV DNA concentration were determined,and HOMA -IR was calculated.Serum levels of leptin and adiponectin were measured by ELISA.Continuous data were expressed as mean ±SD,and Student′s t -test,analysis of variance,linear regression analysis,and multiple regression analysis were ap-plied in the analysis of all experimental data.Results There were no significant differences in serum levels of leptin and adiponectin be-tween patients with chronic HBV infection and the control group (P =0.480;P =0.321),even after stratification by gender (males:P =0.210 /0.895;females:P =0.404 /0.066).After patients with chronic HBV infection were divided into subgroups by HBeAg status,HBV DNA,or ALT level,there were no significant differences in serum levels of leptin and adiponectin between groups (leptin:P =0.820 /0.296 /0.212;adiponectin:P =0.268 /0.760 /0.224).Conclusion For patients with chronic HBV infection,infection status and viral replication level are not significantly correlated with serum levels of leptin and adiponectin.
