LL-37 is the only member of the cathelicidin family known to exist in human acting as an endogenous antibiotic.After removal of the highly conserved N-termini of precursor hCAP18,a 15 000 C-terminal fragment called LL-37 bearing all of the known biological acivity hitherto is liberated by proteinase.LL-37 is active against both Gram-positive and Gram-negtive bacteria.Its antibacterial activity depends on the formation of ?-helical conformation.The cytotoxic activity of LL-37 is inhibited by apolipoprotein A-Ⅰ(apoA-Ⅰ) in the plasma,thereby it can function as a scavenger of LL-37 and prevent host cell damage.In addition to its microbicidal activity,LL-37 has several other functions such as chemotactic,angiogenic action and the ability to bind and neutralize the endotoxin.

ObjectiveTo investigate the effects of alpha-lipoic acid on serum soluble intercellular adhesion molecule-1 (sICAM-1) and high sensitive-C reactive protein (hs-CRP) levels in patients with early diabetic nephropathy (DN).MethodsA total of 61 patients with early DN were randomized into treatment group (n =31 ) and control group ( n =30 ).The two groups were both treated with dietary control and oral hypoglycemic drugs or insulin.Meanwhile,the treatment group was additionally given alpha-lipoic acid 300 mg/d by intravenous infusion for 20 days.The levels of sICAM-1 and hs-CRP in each group were detected.Results The levels of sICAM-1 and hs-CRP were decreased significantly in alpha-lipoic acid treatment group after 20 days of therapy ( [ 198.03 ±23.67] μg/L vs [271.17 ±34.66] μg/L,[5.16 ±0.43] mg/Lvs [7.95 ±0.88]mg/L,P ＜0.01 ).Conclusion alpha-lipoic acid may decrease the expression of slCAM-1 and hs-CRP,and that may be one of the mechanisms to postpone the progress of early DN.

Emodin is the main effective monomer of Rhubarb, which has a variety of pharmacological actions and valuable clinical applications.Recently, there are many reports about molecular mechanisms of emodin pharmacological actions,and they givehighly attention on the dephlogisticating and antineoplastic effects. These effects are achieved through affecting the concentration and transportation of ions, resisting of oxidation and free radical, and affecting the secretion of inflammatory factor and the enzyme activity and apoptosis and so on. This article summarizes the reports and hopes to provide theoretical basis for the practical application.

Objective To prepare the long‐term use and good stability of HBsAg feeble masculine serum ,and the application of controlling quality for HBsAg .Methods The HBsAg positive serum was diluted using calf serum phosphate buffer by grads ,multi‐ple to 1∶2 ,1∶4 ,1∶8 ,1∶16 ,1∶32;HBsAg feeble masculine serum was detected by double antibody sandwich method of enzyme‐linked immunosorbent assay (ELISA) using different reagent lot obtained from two companies for continuous six months .Results The serum ,s diluting multiple which the S/CO ,value between 1 to 3 was 1∶8 ,and the S/CO was 2 .42 ,the CV was 4 .72% .The serum of quality control possessed a good stability in different detection reagents ,the S/CO value range from 2 .41 to 2 .82 ,and the CV value was 4 .24% to 8 .68% .The CV value of HBsAg feeble masculine control serum with 6 months successive detection ranged from 8 .71% to 9 .86% (CV<10% ) .Conclusion The HBsAg feeble masculine serum possessed good stability and precision which is fit for masculine serum in HBsAg test .

Objective To investigate the effect of steroid hormones on lymphatic stomata of ovarian bursa and fluid adsorption. Methods The lymphatic adsorption was traced by trypan blue,and the ultrastructure of the lymphatic stomata and estrogen receptor level of mesothelial cells on ovarian bursa was observed by scanning electron microscopy,transmission electron microscopy and immuno-colloid golden technology. Results The absorption and opening area of lymphatic stomata were enhanced in estrogen group mice,and decreased in androgen group as compared to control group mice.Estrogen receptor was first identified in the nuclei of mesothelial cells on the inner layer of mice ovarian bursa and the level was down-regulated by estrogen and slightly up-regulated by androgen.Conclusion The absorption and the opening area of lymphatic stomata can be regulated by steroid hormones in mice,and the machanism may be related to the expression levels of estrogen receptor in the nuclei of mesothelial cells.

Neuropathic pain is the clinically common disease and does great harm to physical and mental health.Because its pathogenesis is still unclear and there aren′t effective therapeutic tools and the course of chronic pain lasts a long time,the study of neuropathic pain has become the hot spot and the focal point of pain research area.This article reviews various kinds of animal models of neuropathic pain,which can repeat neuropathic pain symptoms of mankind and may be effective ways to make research.By acting on P2X receptors,ATP is the signal of an important transmitting pain.By utilizing animal models of neuropathic pain,it shows that P2X receptors have an important role in the formation,transmission and regulation of pain and may be a new target of neuropathic pain therapy.

Intracranial aneurysm is an abnormal bulging of intracranial artery wall. Its rupture can lead to subarachnoid hemorrhage. About 50% of patients with aneurysmal subarachnoid hemorrhage will die or have poor outcomes. At present, intracranial aneurysm is considered as a complex disease associated with genetic and environmental factors. Although the etiology of intracranial aneurysm is not completely clear, a lot of evidence has shown that the genetic factor plays an important role in the processes of its occurrence, development and rupture. This article reviews the advances in gene linkage research, genome wide association studies, and gene expression research in intracranial aneurysm in recent years.

Enterostomy are a common surgical procedure in the treatment of rectal cancer, has more than 100000 each year in our country requires enterostomy patients, whereas patients with postoperative rehabilitation and nursing leave the family caregivers, the study found that with baseline levels of care for people, and increased mortality 63% of caregivers within five years, attaches great importance to the caregivers of patients with life can avoid the occurrence of another patient, at the same time also can improve the quality of family care, reduce the demand for medical and waste. Therefore, this article will from the permanent patients underwent colostomy care burden of family caregivers, health education needs, psychological burden to understand colostomy caregivers are faced with the problem of our country, explore the mental and physical health of the caregivers related factors, provide the basis for effective follow disease intervention.

OBJECTIVE:To Study the cost-effectiveness among3therapeutical schemes in the treatment of Graves ophthalmopathy.METHODS:A total of94cases with Graves ophthalmopathy were randomized into3groups,Group A was assigned to receive medrat,Group B to receive dexamethasone and Group C to receive prednisone,the outcomes were evaluated in terms of the cost-effectiveness analysis.RESULTS:The costs for Group A,B and C were2956.76yuan,2059.42yuan and31.09yuan,respectively.The total effective rates were93.94%,93.75%and51.72%,respectively.The cost-effec-tiveness ratios were31.47yuan,21.97yuan and0.60yuan,respectively.The incremental cost-effectiveness ratios of Group A and B were69.30yuan and48.26yuan,respectively as against Group C.CONCLUSION:In terms of pharmacoeconomics,Group B is comparatively the best option in treating Graves ophthalmopathy.

Cerebral small vessel disease (CSVD) refers to the syndromes of clinical,cognitive,radiographic and pathological manifestations caused by intracranial small vessel disease.Due to the insidious onset of CSVD,unknown etiology,diverse clinical manifestations,and better short-term prognosis,it is easily ignored,resulting in misdiagnosis,missed diagnosis,and non-standard diagnosis and treatment.This article reviews the advances in research on clinical manifestations,imaging features,diagnosis and treatment of CSVD.
