Objective To evaluate the targeting and photodynamic activity of photosensitizer Ⅰ (PSⅠ)for laryngocarcinoma Hep-2 cells.Methods The photostability of PSⅠ was measured by bleaching assay.The cellular uptake of PSⅠ by Hep-2 cells were evaluated by fluorescence spectroscopy,the effects of PSⅠconcentration,irradiation dose and etc on the viability of Hep-2 cells were investigated by MTT assay.Results After irradiation of 50 min,the OD value of PS Ⅰ decreased 11％,which indicated that the stability of PSⅠ can meet the requirement of PDT.The cellular uptake of PS Ⅰ by Hep-2 cells increased with the concentration of PSⅠ and can be obviously inhibited by the presence of excessive free folic acid (P ＜ 0.01).The results of MTT assays demonstrated that the viability of Hep-2 showed negative correlation with the PSⅠ concentration and irradiation dose.The viability of Hep-2 was only 34 ％ after PDT with 14 μ mol/L of the PS Ⅰ and 18 J/cm2 of irradiation.However,the viability of Hep-2 was still 100 ％ without irradiation,even though the concentration of PS Ⅰ was up to 1 10 μmol/L.The PDT carried out after 24 h of PSⅠ administration can efficiently inhibited the growth of Hep-2 with the survival rate of 32 ％.Conclusion The PS Ⅰ posses satisfactory photostability and lower dark cytotoxicity,and displays significant targeting and photocytotoxicity for Hep-2 cells.

Taxa-4(5),11(12)-diene is the precursor for paclitaxel biosynthesis. The diterpenoid paclitaxel (marketed as Taxol), a plant secondary metabolite isolated from yew, is an effective drug widely used in the treatment of numerous cancers. However, further application of taxol has been restricted due to its low yield in plants and the difficulties in extraction. To increase the intact isoprene flux, we constructed the fusion gene plasmid pBgGGTS and individual cassette plasmid pBgGGgTS to enhance the expression levels of geranylgeranyl diphosphate synthase gene (ggpps) and a taxadiene synthase gene (ts) in Coprinopsis cinerea. These two plasmids were separately transformed into C. cinerea LT2 strain, resulting in several putative transformants. Putative transformants were determined by PCR technique, indicating that 5 out of 13 putative transformants transformed by pBgGGTS and 6 out of 13 putative transformants transformed by pBgGGgTS, respectively. Additionally, the Southern blotting analysis of these 10 transformants confirmed that both ggpps and ts gene were stably integrated into the genome of C. cinerea. Crude extracts from each of the transformants were analyzed. There is no difference in the mycelium extracts among the wild-type LT2 and two types of transformants. However, analysis of culture filtrates indicated that an additional GC peak was found at the retention time of 16.762 min which was absent in the wild type control. The mass fragmentation pattern of this peak had the same diagnostic ions with taxa-4(5),11(12)-diene. According to peak area, the amounts of taxa-4(5),11(12)-diene in each fermented broth were 44 ng/L (transformed with pBgGGgTS) and 30 ng/L (transformed with pBgGGTS), respectively. In conclusion, co-expression of the ggpps and ts gene could increase the taxadiene production in C. cinerea.

Objective: To explore the relationship between the changes of plasma levels of resistin with the contemporary body weigh changes in the same population. Methods: The community based epidemiological surveys were carried out in the same population in Shijingshan district of Beijing at the year of 2005 and year of 2010. A total of 943 subjects with the entire information of cardiovascular related risk factors were enrolled including 316 male with the mean age of (58.2 ± 8.5) years and 627 female with the mean age of (59.3 ± 7.5) years. Plasma levels of resistin in both year of 2005 and year of 2010 in all subjects were recorded, and the subjects were divided into 4 groups based on the quartile levels of resistin. Group①, the subjects with plasma level of resistin ≤ (-0.66) mmol/L,n=239, Group②, resistin level (from -0.67 to 0.25) mmol/L,n=233, Group③, resistin level (0.26-1.24) mmol/L, n=235 and Group④, resistin level ≥1.25 mmol/L,n=236. Pearson correlation study with uni- and multi- regression analysis were conducted to investigate the relationship between the changes of plasma levels of resistin with the contemporary body weight changes in the same population.Results: The uni-variate analysis showed that in female subjects, plasma levels of resistin were obviously related to the percentage (%) of body weight changes (correlation coefifcient: 0.1173), body weight index (kg/m2) changes (0.1521), the% of body weight index changes (0.1412), the waist circumference (cm) changes (0.1228) and the % of waist circumference changes (0.1057) respectively, allP<0.05; while the above changes in male subjects were not signiifcant, allP>0.05. Multi-regression analysis indicated that with adjusted baseline variables, in female subjects, the plasma levels of resistin were obviously related to body weight (kg) changes and the % of body weight changes (regression coefifcient: 0.0261 and 0.2916), body weight index (kg/m2) changes and % of body weight index changes (0.2157 and 0.3072), the waist circumference (cm) changes and the% of waist circumference changes (0.0532 and 0.2738) respectively, allP<0.05; while the above changes in male subjects were not signiifcant, allP>0.05. Conclusion: The changes of plasma levels of resistin are signiifcantly related to contemporary body weight changes in female subjects, but not in male subjects.

Objective To investigate the common initial clinical presentations of primary Sj(o)gren's syndrome (pSS) with pulmonary complications,and to explore the differences between patients with extraglandular manifestations at disease onset (EGM) and those with glandular manifestations at disease onset (GM).Methods A total of 1 341 hospitalized SS patients from 2003 to 2012 were retrospectively reviewed.Of them,102 hospitalized patients with pSS'associated lung disease were analyzed and included.Case control study was performed to explore the differences between the EGM group and the GM group.Results Fifty-one percent of patients were presented with EGM at onset,with significantly shorter disease duration [36 (12,156) m vs 102 (48,159) m,x2=-2.41,P=0.016].Although the mean diagnose time was similiar,only 4％ of the EGM group could be confirmed the pSS diagnose at onset,which was significantly less frequently than that of the GM group (34％,22=15.29,P＜0.01).Case control study revealed that hyperglobulinemia,elevated RF titers and anti-SSA and/or anti-SSB test positive were less predominant in the EGM group [IgG 16(12,21) g/L vs 21 (15,28) g/L,x2=-2.15,P=0.032;22 (20,171) U/ml vs 104 (20,238) U/ml,x2=-l.98,P=0.048;33％ vs 72％,x2=15.78,P＜0.01].The predicted value of TLC and FVC were lower [(87±23)％ vs (97±20)％,x2=-1.96,P=0.050;(8±28)％ vs (100±27)％,x2=-1.70,P=0.089] and HRCT score was higher in EMG group [12(88,15) vs 8(5,13),x2=-1.82,P=0.070].Conclusion EMG at onset is the common initial manifestation of pSS'associated lung involvement.Pulmonary complication is more progressively and severe than those with MG at onset.Anti'SSA positive,elevated RF titer and hyperglobulinemia are not predominant for patients with EMG at onset.

Objective: To explore the prevalence and risk factors of mitral regurgitation (MR) in the population ≥35 years in China in order to provide prevention reference for high risk crowd. Methods: The residents ≥35 years were taken by a stratified multistage sampling method. General information of crowd was collected by predesigned questionnaire and physical examination including life style, disease history, body weight and height. Echocardiography was conducted, fasting blood glucose and blood lipid levels were measured. Results: A total of 28814 subjects were enrolled. The overall MR detection rate was 18.4%, the detection rate in male and female were both 18.4%. The detection rates of moderate and severe MR were 0.3% in the paticipants at (35-50) years, 0.9% at (51-64) years and 2.2% at ≥65 years. MR prevalence showed an increasing trend with aging. Multivariate Logistic regression analysis indicated that age, systolic blood pressure, urban and rural, district, left atrial front and back diameter, left ventricular end diastolic front and back diameter, left ventricular ejection fraction, stroke, atrial fibrillation and heart failure were the risk factors for MR occurrence. Conclusion: MR detection rate was rather high in China. Specific prevention action should be taken for those with theabove risk factors.
