International Journal of Laboratory Medicine 2015;(10):1360-1361
Objective To evaluate the value of (1 ,3)‐β‐D‐glucan(G test) in the diagnosis of invasive pulmonary fungal infection (IPFI)in patients with chronic obstructive pulmonary disease (COPD) .Methods 96 COPD patients with high risk of IPFI were en‐rolled in the study ,and were divided into IPFI group and non‐IPFI group .The G test were performed on those people while the tra‐ditional methods sputum smear and fungal culture were also performed .The (1 ,3)‐β‐D‐glucan concentrations of IPFI group and non‐IPFI group were compared ,and then the areas under receiver operating characteristic curve (ROC) were calculated .The sensi‐tivity ,specificity ,positive predictive value ,negative predictive value ,and the area under ROC of the two methods (G test and tradi‐tional methods) were compared .Results The sensitivity ,specificity ,positive predictive value ,negative predictive value of G test were 89 .5% ,89 .6% ,68 .0% ,97 .2% ,respectively ,when 20 pg/mL was the critical value .Areas under curve were 0 .942 for G test ,and 0 .790 for traditional method .Conclusion The detection of (1 ,3)‐β‐D‐glucan might be faster and with higher positive rate than traditional method ,and could be used for the early diagnosis of IPFI ,provide reference for the treatment .

Traditional Chinese Drug Research & Clinical Pharmacology 1993;0(01):-
Objective To observe the anti- inflammation and analgesic action and anti- urarthritis effect of modified Simiao prescription with polysaccharide removal and thus to screen the effective anti- gout components from modified Simiao prescription. Methods Mouse acetic- acid- induced twisting experiment, mouse xylene- induced auricular swelling experiment, and rat sodium- urate- induced pedal swelling experiment were carried out in this study. Results After the removal of polysaccharides, modified Simiao prescription still kept obvious anti- inflammation and analgesic action and in a dose- effect manner. Conclusion Polysaccharides removal has no influence on the anti- inflammation and analgesic action of modified Simiao prescription .

OBJECTIVETo observe the effect of sodium tanshinone II (A) sulfonate (STS) on Ang II -induced atrial fibroblast collagen synthesis and TGF-beta1 activation.
METHODAtrial fibroblasts of neonatal rats were cultured to determine the content of collagen protein. The original synthesis rate determined by the [3H]-proline incorporation method was taken as the index for myocardial fibrosis. The content of active TGF-beta1 and total TGF-beta1 in cell culture supernatants were tested and cultured by ELISA. The expression of thrombospondin-1 (TSP-1) was assessed by using Western blot.
RESULTAng II could significantly increase the content of atrial fibroblast collagen and the collagen synthesis rate, the TSP-1 expression and the concentration of active TGF-beta1, without any obvious change in total TGF-beta1. After the STS treatment, all of the indexes, apart from total TGF-beta1, were obviously down-regulated.
CONCLUSIONSTS could decrease the secretion of Ang II -induced atrial fibroblast collagen and the synthesis rate. Its mechanism is related to the inhibition of TSP-1/TGF-beta1 pathway.

AIM: To evaluate the changes in central corneal thickness (CCF) caused by mydriasis with Mydrin-P.METHODS: A total of 106 eyes of 53 patients with refractive errors were studied. Each eye had instillation of Mydrin-P to obtain mydriasis. CCT was examined before and after mydriasis using ultrasonic pachymeter.RESULTS: CCT increased significantly after mydriasis with Mydrin-P.CONCLUSION: Mydrin-P can affect the measurement of CCT.

Objective To develop a system failure recovery programs in order to prevent an accident of the hospital computer network system. Methods The network failure was divided into three grades according to its influence. The groups of network malfunction was set up and can immediately start the established program, take effective measures to prevent the situation expand and spread in the event of unforeseen circumstances. Results Through the emergency power supply program, the network route emergency program, cable emergency support program and sector emergency plan, the hospital information systems run normally. Conclusion The issue of large-area network information paralysis is effectively solved and improves the information technology capacity of the hospital.

BACKGROUND:Human umbilical vein endothelial cells transfected with lentivirus containing enhanced green fluorescent protein can be easily traced. The optimal multiplicity of infection and time for producing strong fluorescence intensity can lay the foundation of tracing human umbilical vein endothelial cells in animal models.
OBJECTIVE:To observe expression of lentivirus containing enhanced green fluorescent protein in human umbilical vein endothelial cells, and thereby to find a stable method to label human umbilical vein endothelial cells.
METHODS:Using 0.1%col agenase perfusion digestion, we isolated human umbilical vein endothelial cells, which then were placed into a culture medium containing 20%fetal bovine serum and endothelial cellgrowth factor and observed under an inverted microscope. Fol owing digestion, centrifugation and suspension, the cells were counted and divided into four groups, 5.0×105 cells in each group. After cells were seededonto 24-wel plates, 10μL serum-free Dulbecco’s modified Eagle’s medium was added into the blank group, and lentiviruses containing enhanced green fluorescent protein were added into another three groups for celltransfection respectively at multiplicities of infection of 2, 3, 4. There were three dishes in each group.
RESULTS AND CONCLUSION:After cultured for 5-7 days, isolated cells grew into a single layer and exhibited a cobblestone-like arrangement under a light microscope. In addition, factor VIII related antigen test was positive. A green fluorescence was visible at 24 hours of transfection, and peaked at 72 hours. Transfection efficiency was in a linear growth with the multiplicity of infection. Up to the 21st day of transfection, the green fluorescence was stil visible. After 0, 7, 14, 21 days of transfection, the number of human umbilical vein endothelial cells showed no difference between the transfection group with the multiplicity of infection=3 and blank group, suggesting the proliferative ability of cells has no changes after transfection with lentivirus containing enhanced green fluorescent protein. These findings indicate that the lentivirus containing enhanced green fluorescent protein can highly transfect human umbilical vein endothelial cells, and green fluorescent protein can sustainably express for 21 days but cannot impact the cellproliferation.

OBJECTIVE Tostudytheeffectofeffectivefractions(EFC)frommodifiedSimiaoWan (MSW)onthelevelofuricacidinhyperuricemicratsandinvestigatethemechanism.METHODS Two types of hyperurice mic models were established.A persistant hyperurice mic model was prepared by giving rats oxonic acid 200 mg·kg -1 and feeding the m with hypoxanthine.The models were ig given with modified Simiaowan (MSW)50 g·kg -1 or EFC 1 2.5,25 and 50 g·kg -1 consecutively for 5 d.The models were treated with MSW or EFC 50 g·kg -1 for 3 d.After the final treatment,the uric acid concen-trations in seru m and urine were determined by an auto matic bioche mistry analyzer.The activity of xan-thine oxidase (XOD )in the serum and liver was determined by enzymic colorimetric method.The activity of purine nucleoside phosphorylase (PNP)and uricase was detected by spectrophotometry. RESULTS Comparedwithnormalcontrolgroup,theserumlevelofuricacidinbothmodelgroupswas remarkably increased(P<0.01 ).Compared to model control group,MSW 50 g·kg -1 and EFC 12.5, 25 and 50 g·kg -1 significantly reduced the serum level of uric acid(P<0.05,P<0.01 ),but increased the activity of erythrocyte PNP(P<0.01 )in the oxonic acid potassium-induced hyperuricemia rats. MSW 50 g·kg -1 and EFC 50 g·kg -1 elevated the activity of liver uricase in the nicotinic acid-induced hyperuricemia rats(P<0.05).EFC 50 g·kg -1 also significantly decreased the serum XOD activity of hyperuricemicrats.CONCLUSION EFCsignificantlyinhibitstheserumlevelofuricacidinhyperurice-mic rats,which might involve down-regulation of protein levels of serum XOD to inhibit the production of uric acid and activation of uricase to pro mote the deco mposition of uric acid.
