The complement system, the chief component of innate immunity, is not only required for host defense against pathogens and homeostasis, but also related to the pathogenesis and development of various kidney diseases. Recent study has shown that tissue-derived complement and immune cell-derived complement can each mediate local inlfammation. The comple-ment system acts as a bridge between innate and adaptive immunity. Furthermore it’s also a functional bridge between pathogenic humoral and cellular immune responses in an array of kidney diseases. Increasing evidence links inappropriate complement acti-vation and deifciencies of complement proteins to the pathogenesis of kidney autoimmune disease, ischemia-reperfusion injury, transplant rejection and complications in hemodialysis. The development of pharmacologic agents that target complement in pa-tients with this assortment of immune and/or inlfammatory kidney diseases has the potential to abrogate disease progression and improve patient health.

Objective To observe the dynamic level of platelet activation and to analyze the correlation between platelet activation and systemic inflammatory response syndrome(SIRS)in patients with acute ischemie stroke. Methods Mean platelet component concentration(MPC)and white blood count(WBC)were serially determined in patients with acute isehemic stroke,and other parameters including initial plasma fibrinogen(FIB)and adenosine diphosphate(ADP)aggregative rate were also determined.All parameters were compared between the SIRS group and the non-SIRS group.Correlation was analyzed between initial MPC and SIRS score,WBC,FIB and ADP aggregative rate. Results MPC level was declined slightly on the first day,and was followed by a relatively low MPC level from the second day to the forty-fifth day.The average level was fluctuated between 229 g/L and 242 g/L.There was no significant difference in initial FIB(t=1.835,P=0.07)between the SIRS group and the non-SIRS group,but the differences of other parameters had statistical significance(all P<0.01).In the first three days,MPC level was negatively correlated with SIRS score(r=-0.392,-0.376,-0.341,t=3.484,3.405,3.125 respectively,all P<0.01),but not correlated with WBC,FIB and ADP aggregative rate(P>0.05). Conclusions Platelets maintain an activated state during the entire course of ischemic stroke.The initial level of platelet activation.WBC count and ADP aggregative rate are higher in SIRS patients than in non-SIRS patients.The initial level of platelet activation suggests the severity of SIRS,and may be one of the independent risk factors for SIRS.

The therapeutic effects and mechanisms of traditional Chinese kidney-tonifying drugs in treating osteoporosis have become the focus under study. Pharmacological studies have shown that traditional Chinese kidney-tonifying drugs are promoters for the proliferation of osteoblasts, inhibitors for the activity of osteoclasts, regulators for the estrogen level and its receptor, plays important roles in promoting osteogenesis and suppressing adipogenesis of marrow mesenchymal stem cells (MSCs), modulating the function of OPG/RANK/RANKL system and the metabolism of calcium and phosphorus, as well as antioxidation. The anti-osteoporotic active ingredients and pharmacological action mechanism of traditional Chinese kidney-tonifying drugs are summarized from the perspective of molecular and cell biology in this paper, so as to provide references for the study of their mechanism of anti-osteoporosis and for the development of traditional Chinese kidney-tonifying and bone-strengthening drugs.

AIM: To compare the clinical results of suture method and partial eyelash resection treating for pediatric eyelid trichiasis, and screen an effective method for the treatment of pediatric lower eyelid trichiasis.
METHODS: Fifty-six cases of pediatric patients with lower eyelid trichiasis were randomly divided into a control group and an observation group in accordance with the method of drawing lots, and each group was 28 cases. The control group was treated with suture method, and the observation group was treated with partial eyelash resection. The clinical efficacy, patient satisfaction before and after treatment, and the incidence of complications were compared.
RESULTS:(1) The clinically total effective rate was 74%of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups ( P<0. 05 ); ( 2 ) the satisfaction scores were (3. 89±1. 22) points and (6. 27±1-86) points of the the control group before and after treatment, which were ( 4. 00±1. 34 ) points and ( 8-95±2-34) points of the observation group, and there were statistical differences of the two groups before and after treatment (P<0. 05), and the scores of the observation group were higher than that of the control group ( P<0-05);(3) complications such as swelling and stitches off appeared in both groups, and the rate was 21% in the control group, which was 11% in the observation group, and there were statistical differences between the two groups (P<0. 05).
CONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation;partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

Vibrio parahaemolyticus has been considered as one of the most important foodborne bacterial pathogens.The loop-mediated isothermal amplification(LAMP) that amplifies DNA with high specificity and rapidity under an isothermal condition was applied for rapid detection of this pathogen for the first time.A set of four primers,two outer and two inner primers,was designed specifically to recognize the thermolabile hemolysin gene(tlh) of V.parahaemolyticus.The LAMP reaction mix was optimized.The most optimal reaction temperature and time of the LAMP assay for the tlh gene were 60℃ and 60min,respectively.Genomic DNAs from 28 bacterial strains including 14 V.parahaemolyticus strains were amplified using LAMP,and no amplicon was observed in other bacterial strains.The detection limit of this LAMP assay was around 90 fg of V.parahaemolyticus genomic DNA and 24 colonies forming units for pure cultures.In addition,this method was applied to detect artificially contaminated food samples,and the detection limit was 89 cfu/g for non-cultured artificially contaminated food samples.These results suggested that detection of V.parahaemolyticus by LAMP is an effective and low-cost procedure with high specificity and sensitivity that requires no specialized equipment.This assay is expected to become a valuable tool for rapid detection and identification of V.parahaemolyticus.
