Objective To clarify the pathogen for rubella in Beijing from 2007 to 2010. Methods Beijing Center for Disease Preventipn and Control ( CDC ) collected the specimens (including blood, urine and throat swab specimens) frqm clinically diagnosed rubella cases for serological test and virus isolation. The nucleic acid of rubella virus in clinical specimens and isolations was detected by real-time PCR. Results Fifty-five out of 99 blood specimens were positive for anti- rubella IgM. Fifty-one out of 99 clinically diagnosed rubella cases were confirmed as rubella cases by virus isolation. Seventy-two were confirmed as rubella virus infections with real-time PCR method for detecting the nucleic acid of rubella virus in clinical specimens. Compared with the sequences of reference strains of rubella virus, all of detected rubella virus belonged the IE gene type. Conclusion This study indicates that IE gene type virus was the predominant endemic rubella virus in Beijing.

AIM:To investigate the role of p38 MAPK signaling pathway in the receptor-mediated endocytosis.METHODS:The effects of p38 MAPK on the receptor-mediated endocytosis were observed by using Alexa 594-conjugated Transferrin,in the presence of p38 specific inhibitor SB203580 or ERK pathway specific inhibitor PD98059,or using p38 knockout techniques.RESULTS:In the process of receptor-mediated endocytosis,p38 was activated by phosphorylation.Furthermore,the receptor-mediated endocytosis was inhibited by pretreatment with SB203580 or p38 knockout,while pretreatment with PD98059 had no effect on this process.CONCLUSION:p38 MAPK signaling pathway plays a role in the regulation of receptor-mediated endocytosis.

Obesity is an established risk factor for endometrial cancer. Leptin, a secreted protein of the ob gene by white adipose tissue, plays an important role in the regulation of food intake and energy consumption in the brain and acts as a potential growth stimulator in normal and neoplastic cancer cells. However, a direct role for leptin in endometrial cancer has not been demonstrated. In the present study, the effect of leptin on the proliferation of Ishikawa endometrial cancer cells was investigated as well as the possible mechanism(s) underlying this action in endometrial cancers which express both short and long isoforms of leptin receptors. The expression of leptin receptor (ObRb) in Ishikawa cells was detected by RT-PCR and Western blotting. The cells after serum starvation, were treated by leptin with various concentrations (0, 10, 50, 100, 150 ng/mL) for different durations (6, 12, 24 h). The effect of leptin treatment on cell proliferation was examined by MTT assay. Meanwhile, inhibitory effect of Janus tyrosine kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) inhibitor AG490 or extracellular signal-regulated kinase 1/2 (ERK1/2) inhibitor PD98059 on the proliferation of Ishikawa cells induced by leptin was also studied. Ishikawa cells were treated with 100 ng/mL leptin for various periods (0, 20, 40, 60 min), and the levels of STAT3 phosphorylation and ERK1/2 phosphorylation were examined by Western blotting. The results showed that leptin induced the phosphorylation of STAT3 and the activation of ERK1/2 in a time- and dose-dependent manner in the Ishikawa endometrial cancer cells. Blocking STAT3 phosphorylation with the inhibitor AG490, or blocking ERK1/2 activation by the specific ERK1/2 kinase inhibitor, PD98059, abolished leptin-induced proliferation of Ishikawa cells. In addition, leptin was found to potently induce the invasion of endometrial cancer cells in a Matrigel invasion assay. Leptin-stimulated invasion was effectively blocked by pharmacological inhibitors of STAT3 (AG490) and ERK1/2 kinase (PD98059). These results suggested that leptin promotes endometrial cancer growth and invasiveness by activating STAT3 and ERK1/2 signaling pathways and therefore blocking its action at the receptor level can be a rational therapeutic strategy.

ObjectiveTo study the expression of matrix metallopro-teinase-2 (MMP-2),matrix metalloproteinase-9 (MMP-9) in the pancreatic carcinomas. Methods MMP-2,MMP-9 expression were detected by immunohistochemistry in surgically resected specimens ( cancer tissues,cancer-adjacent tissues and normal tissues) from 30 PC patients,11 pancreatitis patients and 6 normal patients.the results were analyzed combined with clinical pathologic characteristics.The data was analyzed by Chi-Square test.ResultsThere was no expression of MMP-2,MMP-9 in normal pancreatic tissues.Both of MMP-2 and MMP-9 expressions were 18.2％ in chronic pancreatitis titssues.Expression of MMP-2,MMP-9 were higher in cancer tissues than in cancer-adjacent tissues(63.3％ vs 23.3％,56.7％ vs 40.0％,P ＜0.05).There were positive correlation between MMP-2,MMP-9 expression and lymph nodal metastasis,tumor sizes,clinical stage and differentiation of tumor(P ＜0.05).Conclusions The expression of MMP-2 and MMP-9 was high,and linked to its unfavorable prognosis.

This paper is aim to investigate the pharmacokinetics and absolute bioavailability of neoline in Beagle dogs, and provide a theoretical basis for further study. Ethyl acetate was used for liquid-liquid extracting after 10% ammonia alkalizing. The method of UPLC-Q-TOF-MS was established for the determination of neoline plasma concentrations. Beagle dogs were orally or intravenously administered with neoline for pharmacokinetic and absolute bioavailability study. Good linear relationship of neoline was found over the range of 0.1-4 mg x L(-1) (R2 = 0.9982) and 2-100 microg x L(-1) (R2 = 0.9945). Intra-and inter-day precision, expressed as the relativestandard (RSD) were less than 5.0%. Accuracy, expressed as the relative error (RE) was within 90.0%-115%. The recovery of neoline in dog plasma was more than 80%. After 6 mg x kg(-1) for ig and 1 mg x kg(-1) for iv administration of neoline, the main pharmacokinetic parameters were analyzed with Winnonlin software. t(1/2) were (313.88 +/- 63.18), (236.33 +/- 229.84) min, and AUC(0-infinity) were (58,027.40 +/- 14,132.69), (473,578.02 +/- 82,333.08) min x microg x L(-1) for ig and iv administration respectively. The absolute bioavail ability was (73.15 +/- 10.29) %. The method of UPLC-Q-TOF-MS described in the report was sensitive, reliable and specific, and suitable for pharmacokinetic study of neoline in Beagle dog. The high absolute bioavailability of neoline in dog suggested good absorption of neline which was worth of further investigation.

Objective: To observe the effect of electroacupuncture (EA) on serum interleukin (IL)-6, IL-8 and IL-10 in rat models of cerebral ischemia-reperfusion, and to discover the mechanism of EA in preventing and treating cerebral ischemia.
Methods:Male Sprague Dawley (SD) rats were randomized into a sham-operation (SO) group, a model control (MC) group, and an EA group, which were sub-grouped into a 6-hour group and a 24-hour group. In the SO group, rats only received vessel separation with filament placed inside without any treatment. In the MC and EA groups, the focal cerebral ischemia-reperfusion model was induced by using modified Longa method with intraluminal filament. The MC group didn’t receive any treatment;the EA group received EA at Baihui (GV 20) and Dazhui (GV 14) with sparse-dense wave for 30 min. The levels of serum IL-6, IL-8 and IL-10 were detected by using Elisa test.
Results: Six hours after ischemia-reperfusion injury, the levels of serum IL-6, IL-8 and IL-10 in the MC group were significantly higher than those in the SO group (P<0.01, P<0.05, P<0.05);the level of serum IL-8 in the EA group was significantly lower than that in the MC group (P<0.05), while there were no significant differences in comparing IL-6 and IL-10 between the EA group and the MC group. Twenty-four hours after ischemia-reperfusion injury, the levels of serum IL-6 and IL-8 in the EA group were significantly lower than those in the MC group (both P<0.05), while there were no significant differences in comparing the level of IL-10 among the three groups.
Conclusion:Early intervention by EA can regulate the levels of serum IL-6 and IL-8 in cerebral ischemic injury.
