Inflammatory bowel disease (IBD) is a group of chronic inflammatory diseases of the intestine mediated by abnormal immunological mechanism caused by multiple etiological factors.The main treatment at present is anti-inflammation and immunosuppression,but with severe side effects and poor efficacy.Vitamin D3 has immunoregulatory,anti-inflammatory,and antineoplastic functions.Vitamin D,as a novel immunoregulator,may provide a new treatment option for patients with IBD.This article will review the research progress on the following four aspects:the relationship of vitamin D with innate immunity,adaptive immunity,and pathogenesis of IBD,and vitamin D supplement in IBD patients.

In recent years, microRNAs were shown to be one of the key factors in post transcriptional gene regulation which are involved in occurrence, development of many diseases. In the field of kidney disease research, the role of microR?NAs attracted more and more attention. Diabetic nephropathy is one of the major causes of end-stage renal disease, whose pathogenesis however has not been fully elucidated yet. This article reviews the role of microRNAs in the pathogenesis of dia?betic nephropathy.

The effects of Verapamil ( Ver ) . Aspirin ( ASA ) and ASA+ Ver on platelet aggregation and generation of thrombosis were studied. ASA and Ver inhibited rabbit platelet aggregation in vitro and rat platelet aggregation in vivo induced by ADP, also prolonged the occlusion time of thrombosis that was induced electrically in the carotid artery of the rat, and reduced the death rate resulted from pulmonary thrombosis that was induced with inducer composed of collagen and epinephrine iv in mice. The effects of Ver and ASA were markedly increased when combined, meanwhile all showed good dose-dependant manner.

Objective To explore the treatment to craniocerebral injury.Methods 6 patients suffered from serious, developing head injury with epidural and subdural hematoma were processed by cone socket hematoma drainage in ward before hematoma was eliminated.Results Hematoma drainage can be performed within 20 min after hospitalization. No case died and no infection occured. The score of Glasgow Outcome Scale were Ⅴ(2 cases), Ⅳ(2 cases),Ⅲ(1 case) and Ⅱ(1 case) 3 months after operation.Conclusion Cone socket hematoma drainage in ward is a good method to treat craniocerebral injury.

Objective To screen the conservative,stable and specific DNA signature sequence in the plasmid of Yersinia pestis.Methods Specific validation trials and stability of the qualification test were carried out to 40 strains of Yersinia pestis,47 strains of non-Yersinia pestis of home and wild types of rodent in Yunnan,by using 32 DNA sequences derived from Yersinia pestis in the plasmid and conventional PCR technology,and Yersinia pestis vaccine strain EV76 as a positive control.Results Four pairs of relatively conservative,stable and specific DNA marker genes were screened:YPMT1.05c,YPMT1.03c,YPMT1.42 and YPMT1.04c.Conclusions The 4 pairs of Yersinia pestis DNA signature sequences can be used for rapid diagnosis of plague.

AIM: To study the infiltration of polymorphonuclear neutrophils ( PMNs ) after conjunctival flap covering in alkali-burned cornea.
●METHODS: Rabbit cornea alkali-burned model was made, then 50 rabbits were randomly divided into the experimental group ( n=25 ) and the control group ( n=25 ) . At the same time the surgery of conjunctival flap covering was given to rabbits of the experimental group. The condition developing of alkali-burned cornea was observed by slit lamp biomicroscopy, and took photos in two groups. The infiltration of PMNs was identified by hematoxylin eosin ( HE) staining in different periods.
●RESULTS:The quantity of PMNs increased on the 3d, reached the lower level on 7d, shown a peak on the 14d, then decreased gradually. PMNs level of the experimental group was significantly lower than that in the control group, and the difference of 3, 14 and 21d was significant (P<0. 05).
●CONCLUSION: During the wound healing process, alkali - burned cornea has close relation with the infiltration of PMNs. The treatment of conjunctival flap covering for the severe alkali-burned cornea was found to have good effect.

Incidence of thyroid cancer has continuously increased in the last three decades globally. A similar trend of thyroid cancer incidence appeared in China. New cases and deaths of thyroid cancer in China accounted for 15.6% and 13.8% of the global new cases and deaths in 2012. The incidence in East China was the highest while that in Middle China was the lowest. Thyroid cancer was more common in urban areas than in rural counterparts. The incidence was substantially higher in female patients than male. Thyroid cancer occurred most commonly in middle age. Radiation exposure, iodine suffciency or deifciency, sex hormone and genetic mutations were risk factors for thyroid cancer. To prevent it, potassium iodide should be taken to prevent radiation fallout in nuclear accidents, unnecessary exposure to radiation from medical imaging is reduced, iodine surveillance system is improved and appropriate standards for iodized salt are established.

Objective To study the features and its effect factors of T lymphocyte apoptosis in preterm neonates. Methods The susceptibility to apoptosis of T lymphocytes were determined in 30 full-term neonates and 19 preterm neonates by percentage calculation of apoptosis cell and DNA fragmentation analysis. The expression of CD 25 and CD 38 in peripheral blood mononuclear cells and the volume of IL-2 and IL-6 produced by lymphocytes incubated for 48 h was determined by immunofluorescence procedure and ELISA. Results T lymphocyte apoptosis was easier in preterm(27.2?2.7)%,(34.8?3.9)% than in full-term neonates(21.1?1.4)%,(27.9?2.3)% at incubating 24 h, 48 h(t=10.547,7.789;P
