Objective To measure the fluorescence spectral information of UVRF in the facial skin of patients with acne vulgaris and seborrheic dermatitis and to comprehend the optical properties of UVRF.Methods The lesions were squeezed to extract the sebaceous secretions containing UVRF in the facial skin.Ocean Optics USB2000 +F02243 Spectrometer and the 308nm excimer laser were used as an excitation light source to measure the signal of the LIF spectrum of UVRF in 6 acne vulgaris and 4 seborrheic dermatitis patients' facial part,compared with protoporphyrin Ⅸ.Results 1-4 peaks were detected in 10 patients' UVRF specimen respectively.The fluorescence spectra's characteristic peak of UVRF in 10 patients was at 680 nm.Protoporphyrin Ⅸ was at 688 nm and more gentle and generous than UVRF's characteristic peak.Conclusions LIF system can be used to detect the fluorescence spectroscopy of UVRF.UVRF has similar spectral characteristics to protoporphyrin Ⅸ,but it is not the same species.

Objective The function of regional myocardium of patients with myocardial infarction(MI) treated by intra-coronary stenting was determined with quantitative tissue velocity imaging(QTVI).Methods Twenty healthy controls and 24 patients with acute anterior myocardial infarction underwent QTVI with high-frame rates. The myocardial tissue velocity imaging in the apical 4-chamber view and apical 2-chamber view and apical longitude view were digitized and stored. Off-line ventricular walls regional velocity profiles along long axis were obtained, and systolic peak velocities (Vs) and early and late diastolic peak velocities (V E and V A) of 12 regional segments were measured.Results Under normal and ischemic conditions, 6 ventricular walls showed significant basal-apical myocardial velocity in the long-axis reduction in V S and V E and V A were significantly reduced in the abnormal segments in patients with MI. Conclusion QTVI can be used to analyze regional myocardial motion in the long-axis quantitatively and synchronously;intra-coronary stenting can obviously improve regional myocardial function of left ventricle,especially the diastolic function.

Objective To explore the clinical efficacy of anti-helicobacter pylori (HP) treatment on patients with type 2 diabetes mellitus and HP infection.Methods A total of 112 type 2 Diabetes patients were diagnosed with HP infection in Combine Traditional Chinese and Western Medicine Hospital of Taizhou from April 2012 to June 2016.These patients were divided into control and treatment group based on the preprandial blood glucose averages from lower to higher hierarchy.Thus,there were 56 patients in each of the two groups.The control group was given Motilium and Talcid for gastric symptoms in addition to anti-diabetes treatment,while the treatment was administered the same treatments as well as the quadruple anti-HP therapy (omeprazole,amoxicillin,clarithromycin and colloidal-bismuth-subcitrate,with Talcid stopped while colloidal-bismuth-subcitrate was administered).The anti-HP lasted for 14 days.The two groups were compared the gastric symptoms,the blood glucose levels,and the HbA1c one month after treatment.Half a year and one year post treatment,the two groups were compared the gastric mucus signs under gastroscopy.Results The improvement rates after treatment with the treatment group in abdominal pain,bloating,regurgitation,belching and diarrhea/constipation were 88.5％ (23/26),83.3％ (25/30),74.1％ (20/27),83.9％ (26/31),82.6％ (19/23),respectively,and with the control group being 29.2％(7/24),32.1％(9/28),28％(7/25),30.3％(10/33),18.2％ (4/22),respectively.The differences between the two groups were significant (x2=8.06,6.62,3.92,7.65,6.66,P＜0.05 or P＜0.01).The control group did not show significant changes in preprandial glucose levels,the glucose levels two hours post meals and the HbA1c(P＞0.05) while the treatment group showed statistically significant changes(P＜0.05 or P＜0.01).The differences in the three indicators after treatment between the two groups were significant (t =4.07,7.85,4.16,P＜ 0.05).The Gastric mucus signs under gastroscopy showed improvements in both groups after treatment.The improvement rates with the treatment group were 86.2％(25/29),86.7％ (13/15),77.8％ (14/18),72.7％ (8/11) respectively,with the control group being 36％ (9/16),27.3％ (3/11),13.3％ (2/15),14.3％ (1/7),respectively.The differences between the two groups were significant (x2 =6.71,4.12,4.38,3.85,P ＜ 0.05 or P＜ 0.01).The effectiveness rate,which was based on combined improvements in gastric symptoms,glucose levels and gastric mucus signs,was 76.8％ with the treatment group and 32.1％ with the control group.The difference was statistically significant (x2 =6.78,P＜0.01).Conclusion Anti-HP treatment can relieve the gastric symptoms,stabilize the glucose levels,and help to reverse the changed gastric mucus.All these can reduce the complications of the diabetes and improve the prognosis of the patients.

OBJECTIVEThis research explores the regulatory role of bone morphogenetic protein 2 (BMP2) in the expression of sclerostin in OCCM-30 cementoblast.

METHODSOCCM-30 cementoblasts were treated with 50 and 100 ng · mL⁻¹ BMP2 for 3, 5, and 7 days. SOST mRNA was detected by real-time quantitative polymerase chain reaction (RT-PCR). Western blot analysis was employed to detect the sclerostin levels in the nucleus. Five groups were prepared for the experiments: control, BMP2, BMP2+dorsomorphin, BMP2+SB202190, and BMP2+PD98059. OCCM-30 was pretreated with BMP2 for 3 and 5 days, and then the sclerostin and SOST mRNA levels were measured.

RESULTSRT-PCR and Western blot analyses showed that BMP2 upregulated the expression of SOST in a concentration-dependent manner. SOST expression increased with time (P < 0.05). Moreover, sclerostin levels of BMP2+dorsomorphin, BMP2+SB202190, and BMP2+PD98059 groups were lower than that of the BMP2 group, and the sclerostin level in BMP2+dorsomorphin group was lowest (P < 0.05).

CONCLUSIONThe upregulation of SOST by BMP2 in OCCM-30 is mainly mediated by the BMP2/Smad signal pathway.

The research on intracellular trafficking of adenovirus has been described mainly through observations of subgroup C adenoviruses in transformed cell lines. The basic elements of the trafficking pathway include binding to receptors at the cell surface, internalization by endocytosis, lysis of the endosomal membrane, escape to the cytosol, intracellular trafficking along microtubules, nuclear pore docking, and viral genome translocation into the nucleus. More than 80% of the adenovirus genome is delivered to the nucleus in a highly efficient manner in approximately 1 h. However, exceptions to this trafficking pattern have been noted, including: variations based on target cell type, cell physiology, and adenovirus serotype. This review summarizes mechanism of adenovirus infection pathway and intracellular trafficking, providinging a foundation for the development of clinical adenoviral vector.
