International Journal of Laboratory Medicine 2014;(16):2187-2188,2196
Objective To investigate the detection of anti-cyclic citrullinated peptide(anti-CCP)antibody,alkaline phosphatase (ALP),glucose-6-phosphate isomerase(G6PI)and rheumatoid factor(RF)in the diagnosis of rheumatoid arthritis(RA).Methods Serum RF,anti-CCP body,ALP and G6PI were detected in 206 cases of RA,68 cases of other autoimmune diseases and 48 persons with the healthy physical examination,at the same time the erythrocyte sedimentation rate(ESR)was measured;the sensitivity and specificity of each indicator and the relationship between each index and RA′s diagnosis.Results The serum level of each index in the RA group was significantly higher than that in the other two groups(P <0.05).The sensitivity of RF,anti-CCP antibody and G6PI for diagnosing RA is similar;the specificity of anti-CCP body was highest(94.8%),RF was similar to G6PI;ALP with rela-tively lower sensitivity and specificity also reflected the potential of RA to some extent.Conclusion The simultaneous detection of serum RF,anti-CCP body,G6PI and ALP can improve the accuracy of early diagnosis of RA,reduce the missed diagnosis and guide the clinical treatment.

Traditional Chinese medicine has a long history of intranasal administration. Compared with the other administration routes, intranasal administration has the benefits of fast absorption, high bioavailability, high brain-targeting and non-invasive. In the past few years we take "Xingnaojing" and "Tongqiao Sanyu formula" as model drug and studied pharmacokinetics of effective components of different polarities. MDCK/MDCK-MDR1 cells were used to simulate blood brain barrier to study the permeate behaviors of different drug and the mechanism of enhancing effects of aromatic medicine. Then a microemulsion (modified by mPEG2000-PLA) was prepared for intranasal administration, and the pharmacokinetics and investigated tissue distribution were studied by fluorescence imaging. The irritation of the drug and different preparations were studied on human nasal epithelial cell (HNEC) cell and living animals. In this paper, we reviewed the achievements and hope that it can provide constructive suggestions for the future research.

Objective: To search for a best method for management mandible fractures by evaluating the effects of different treatments.Methods: We retrospectively analyzed 148 cases of mandible fractures treated in our department from January 1996 to June 2007.Results: Among the total number,134 cases were restored to normal occlusion,while 6 cases experienced local occlusive disfunction and 8 malocclusion.The effect of treatment was correlated with the types of fracture and methods of diaplasis.Conclusion: Mandible fractures should be treated with a new concept of combined and sequential multidisciplinary methods.Sound diaplasis followed by reliable fixation can produce a satisfying curative effect.At present,intermaxillary elastic traction with internal titanium plate fixation is the most effective method for the management of mandible fractures.

In order to investigate the characteristics of transdermal delivery of ferulic acid under the treated of microneedle arrays and the influence on permeability of rat skin capillaries, improved Franz-cells were used in the transdermal delivery experiment with the rat skin of abdominal wall and the length of microneedle arrays, different insertion forces, retention time were studied in the influence of characteristics of transdermal delivery of FA. The amount of FA was determined by HPLC system. Intravenous injection Evans blue and FA was added after microneedle arrays treated. Established inflammation model was built by daubing dimethylbenzene. The amount of Evans blue in the rat skin was read at 590 nm wavelength with a Multiskan Go microplate reader. Compared with passive diffusion group the skin pretreated with microneedle arrays had a remarkable enhancement of FA transport (P <0.01). The accumulation of FA increased with the enhancement of insertion force as to as the increase of retention time. Microneedle arrays with different length had a remarkable enhancement of FA transport, but was not related to the increase of the length. The research of FA on the reduce of permeability of rat skin capillaries indicated that the skin pretreated with microneedle arrays could reduce the content of Evans blue in the skins of rat significantly compared with the untreated group. The permeation rate of ferulic acid transdermal delivery had remarkable increase under the treated of microneedle arrays and the length of microneedle arrays ,the retention time so as to the insertion force were important to the transdermal delivery of ferulic acid.

An HPLC method for the determination of geniposide concentration in mouse plasma was developed and the pharmacokinetics after intranasal administration of Xingnaojing microemulsion (XNJ-M) and mPEG2000-PLA modified Xingnaojing microemulsion (XNJ-MM) were investigated. Eighty mice were treated by XNJ-M and XNJ-MM nasally. The plasma samples were collected at different times and the drug in samples was detected by HPLC. The pharmacokinetic parameters were calculated by the software of Kinetica. The pharmacokinetic parameters of geniposide of XNJ-M were C(max) (4.36 +/- 2.69) mg x L(-1), t(max) 1 min, MRT (29.73 +/- 4.54) min, AUC (53.63 +/- 14.03) mg x L(-1) x min. The pharmacokinetic parameters of geniposide of XNJ-MM were C(max) (9.75 +/- 4.14) mg x L(-1), t(max) 1 min, MRT(22.34 +/- 2.90) min, AUC (131.87 +/- 40.13) mg x L(-1) x min. Geniposide can be absorbed into blood in a higher degree after intranasal administration with XNJ-MM compared to XNJ-M, which maybe caused by its less irritating and more absorption.

OBJECTIVETo evaluate the curative effect of Qingkailing Injection (QKL) for treatment of children's respiratory syncytial virus pneumonia of phlegm-heat obstructing Fei syndrome pattern (SVP-PH) depending upon main symptom assessment.
METHODSA Chinese-Western medicine comparative trial was conducted on 206 children with SVP-PH in two groups treated with Ribavirin injection plus compound guaiacol potassium sul-fonale oral solution (as control group) and QKL injection plus Ertong Qingfei oral liquid (as treated group) respectively, for 10 days. The curative effectiveness on four main symptoms (fever, cough, sputum and short breath) were evaluated at different time-points.
RESULTSThe effectiveness in the treated group at various time-points was superior to that in the control group, showing the earlier initiating time (on the 4th day) and the preponderances on cough and sputum ran all through the whole course.
CONCLUSIONChinese medicine shows a multi-target effect in treating children's SVP-HP.

Prolyl-4-hydroxylase domain (PHDs) family is one of the most important regulatory factors in hypoxic stress. PHD2 plays a critical role in cells and tissues adaptation to the low oxygen environment. Its hydroxylation activity regulates the stability and transcriptional activity of the hypoxia-inducible factor 1 (HIF-1), which is the key factor in response to hypoxic stress. Subsequently, PHD2 acts as an important factor in oxygen homeostasis. Studies have shown that PHD2, through its regulation on HIF-1, plays an important role in the post-ischemic neovascularization. Furthermore, under hypoxic condition, PHD2 also regulates other pathways that positively regulate angiogenesis factors HIF-1 independently. Moreover, recently, several evidences have also shown that PHD2 also affects tumor growth and metastasis in a tumor microenvironment. Based on these facts, PHD2 have been considered as a potential therapeutic target both in treating ischemic diseases and tumors. Here, we review the molecular regulation mechanism of PHD2 and its physiological and pathological functions. We focus on the role of PHD2 in both therapeutic angiogenesis for ischemic disease and tumor angiogenesis, and the current progress in utilizing PHD2 as a therapeutic target.

Vaccination is the primary strategy for the prevention and control of pandemic influenza. Because influenza virus is highly variable across strains, universal influenza vaccines need to be developed to address this problem. This review describes the research progress in conserved epitopes of influenza virus, the advances in the research and development of universal influenza vaccines based on the relatively conserved sequences of NP, M2e, HA2, and headless HA, the mechanisms of cross-protection, and the methods to improve cross-protection.
