OBJECTIVE:
To explore the relationship between the expression of EIIIA+ fibronectin in incised wound of rat's skin and injury time.
METHODS:
The wounding model was established by cutting the dorsal skin of 48 adult SD rats. The rats were sacrificed at the pre-set injury time as immediately, 0.5 h, 1 h, 2 h, 3 h, 4 h, 6 h, and 8 h. The skin samples were taken at the margin of wound. The expression of the EIIIA? fibronectin was detected by immunohistochemistry and Western blotting and the relationship be- tween its expression and injury time was observed. Results The expression of EIIIA+ fibronectin was not observed immediately. The basal cell of skin began to show positive expression 0.5 h after injury. With the extension of injury time, positive staining became stronger. The value of relative optical density was gradually increased with prolonged injury time by the Western blotting analysis.
CONCLUSION
The expression of EIIIA+ fibronectin could be used for estimation of injury time in the early stage of skin injury.

OBJECTIVETo investigate the clinical and pathologic characteristics of anti-glomerular basement membrane(GBM) disease with normal renal function.
METHODSThe clinical and pathologic data of 6 patients with anti-GBM disease and normal renal function in Peking Union Medical College Hospital were reviewed retrospectively. Furthermore, 29 patients with anti-GBM disease and impaired renal function in the same period in the same hospital were enrolled as the control group. Factors that may influence the prognosis were analyzed.
RESULTSSix (17.1%) of all 35 patients maintained normal renal function for 12-133 months during follow-up. Five patients had microhematuria and proteinuria, one had pulmonary hemorrhage only, and three manifested as Goodpasture syndrome. Renal biopsies from 4 patients revealed linear deposition of IgG 2+-3+ along the glomerular capillary walls by immunofluorescence. As shown by normal light microscopy, mild mesangial proliferation and crescentic glomerulonephritis with a large amount of fibrinoid necrosis of glomerular capillary walls were observed in different patients; however, most pathological changes were mild. Five of these six patients were treated with immunosuppressive drugs and/or plasma exchange. Compared with the control group, the 6 patients with normal renal function had significantly higher hemoglobin[(77.97±20.62 vs.(99.67±19.80 g/L P=0.024], lower titers of anti-GBM antibody[(224.34 ± 145.79 vs.(80.23 ± 85.73 EU/ml P=0.027], and lower ratio of glomeruli with crescents[(0.58±0.29 vs.(0.17±0.27 ,P=0.005]. These 6 patients with normal renal function were followed up for 12-133 months, among whom 4 patients achieved complete remission and 2 had mild proteinuria and microhematuria.
CONCLUSIONAnti-GBM disease with normal renal function is not uncommon. Most patients have mild pathologic changes and good prognosis.

OBJECTIVETo establish an early warning model to simulate the outbreak of influenza based on weather conditions and Yunqi theory, an ancient calendar theory of Chinese medicine (CM).
METHODSTianjin, a northeastern city in China, was chosen as the region of research and applied the influenza-like illness attack rate (ILI)% as the baseline and warning line to determine the severity of influenza epidemic. Then, an influenza early warning model was constructed based on the theory of rough set and support vector machines (RS-SVM), and the relationship between influenza and meteorology was explored through analyzing the monitoring data.
RESULTSThe predictive performance of the model was good, which had achieved 81.8% accuracy when grouping the obtained data into three levels that represent no danger, danger of a light epidemic, and danger of a severe epidemic. The test results showed that if the host qi and guest qi were not balanced, this kind of situation was more likely to cause influenza outbreaks.
CONCLUSIONSThe outbreak of influenza closely relates to temperature, humidity, visibility, and wind speed and is consistent with some part of CM doctrine. The result also indicates that there is some reasonable evidence in the Yunqi theory.

Multiplex reverse transcription-polymerase chain reaction (mRT-PCR) is currently available in virus detection and defined as the simultaneous amplification of two or more DNA/RNA targets in a single reaction vessel. In this study, we attempted to modify the conventional mRT-PCR technique on a basis of GenomeLab Genetic Analysis System (GeXP). Initially, we optimized the analytical validation of the GeXP analyzer and its design of workflow and simultaneously detected eight arboviruses that related to epidemic encephalitis by verifying the specificity of mRT-PCR with Japanese encephalitis virus(JEV) cell cultures and positive strains identified previously and determining the sensitivity with in vitro-transcribed RNA of serial dilutions. The GeXP system after optimization could amplify the specific fragments related to the viruses and exposed specifically a total of 13 target genes out of eight types of arboviruses at the level of 10(2) copies/microL, and the findings suggest that the novel protocol we developed can be high-throughput and highly specific and sensitive as well as quickness in screening of the encephalitis viruses, and is promising in detection of encephalitis-associated viruses for molecular epidemiological studies.

OBJECTIVETo observe the expression of connective tissue growth factor (CTGF) in the tubulointerstitium in type 2 diabetic KKA(y) mice and the effect of rosiglitazone on it.
METHODSKKA(y) and C57 BL/6 mice aged 16 weeks ( n = 5 in each group) were sacrificed as controls before treatment. Another 20 KKA(y) mice were treated with rosiglitazone (30 mg x kg (-1) d (-1), n = 10) or placebo (n = 10). The mice were sacrificed at 20 and 24-week-age (n = 5 at each time point). Protein expression of transforming growth factor-beta1 (TGF-beta1 ), CTGF, peroxisome proliferator-activated receptor-gamma (PPARgamma) , and fibronectin were assayed by Western blot, while protein CTGF, PPARgamma, and alpha-smooth muscle actin ( alpha-SMA) were assayed by immunohistochemistry in kidney tissue sections.
RESULTSProteinuria was significantly decreased in mice aged 24 weeks treated by rosiglitazone than same-aged mice treated with placebo [ (44. 53+/-1. 96) vs (63. 66 +/-5. 57) microg/24 h, P < 0. 05 ]. The expressions of TGF-beta1, CTGF, and fibronectin in mice aged 20 weeks treated with rosiglitazone decreased by 37% , 21% , and 52% than same-aged control (P <0. 01) , and those were decreased by 61% , 50% , and 51% in mice aged 24 weeks treated with rosiglitazone compared with same-aged control mice (P < 0. 01). CTGF in the tubulointerstitium were respectively downregulated by 25% and 44. 9% in treated mice aged 20 weeks and 24 weeks compared with the same-aged control mice ( P < 0. 01). The PPARgamma appeared in diabetic mice and increased by 18. 1% in mice aged 24 weeks and treated with rosiglitazone than the same-aged control mice (P <0. 05).
CONCLUSIONHeterogeneous rosiglitazone may upregulate the expression of PPARgamma in renal cortex, and remarkably inhibit the expressions of CTGF in the tubulointerstitium and renal cortex in diabetic KKA(y) mice.

OBJECTIVETo investigate the effect of curcumin (Cur) on radiosensitivity of nasopharyngeal carcinoma cell CNE-2 and its mechanism.
METHODThe effect of curcumin on radiosensitivity was determined by the clone formation assay. The cell survival curve was fitted by Graph prism 6. 0. The changes in cell cycle were analyzed by flow cytometry (FCM). The differential expression of long non-coding RNA was detected by gene chip technology. Part of differentially expressed genes was verified by Real-time PCR.
RESULTAfter 10 micro mol L-1 Cur had worked for 24 h, its sensitization enhancement ratio was 1. 03, indicating that low concentration of curcumin could increase the radiosensitivity of nasopharyngeal carcinoma cells; FCM displayed a significant increase of G2 phase cells and significant decrease of S phase cells in the Cur combined radiation group. In the Cur group, the GUCY2GP, H2BFXP, LINC00623 IncRNA were significantly up-regulated and ZRANB2-AS2 LOC100506835, FLJ36000 IncRNA were significantly down-regulated.
CONCLUSIONCur has radiosensitizing effect on human nasopharyngeal carcinoma CNE-2 cells. Its mechanism may be related to the changes in the cell cycle distribution and the expression of long non-coding IncRNA.
