Objective To investigate the association between single nucleotide polymorphisms (SNP) rs 653765 and rs514049 inADAM10gene and clinical characteristics in asthma in Han Chinese children. MethodsA case-control study was performed in that research, and 221 children with asthma were recruited and an other 236 normal children were recruited as controls. The genotypes of two SNPs in ADAM 10 gene were detected using PCR-RFLP. And all data were analyzed by SPSS 19 . 0 . Results In case-controlled study, we found the frequency of TT genotype in case group was higher than that of controlgroup (P=0 . 028 ), and the frequency of T allele was higher than that of control group (P=0 . 008 ). The genotypes and alleles of rs 514049 was not associated with asthma (P=0 . 604 , 0 . 356 ).There were no difference in serum ADAM 10 levels between asthma and control group (P=0 . 238 ), but in asthma group we found patients with TT genotype may have a higher level ADAM 10 than the one with CC genotype (P=0 . 034 ). The polymorphism of rs 653765 was not associated with the level of C-reaction protein, the number of LYM, IgE and EOS% (P>0 . 05 ). Conclusions The genotype of rs 653765 in ADAM 10 gene was associated with asthma in the central of China, and T allele was a risk factor. The polymorphism of rs 653765 might be associated with the levels of ADAM 10 .

Objective To investigate the effect of erythropoietin on the proliferation,differentiation,and apoptosis of the cultured neonatal porcine islet cells in vitro.Methods Neonatal porcine islet cells were separated and pured from neonatal pigs with collagenase digestion and tissue culture,and their viability and purity were tested. The neonatal porcine islet cells were divided into a control group and an experimental group.The experimental group was treated with erythropoietin but not the control group,and the insulin secretion responsiveness induced by low and high glucose stimulation in the islet was tested after 5 days. Cells were counted and the activation of amplification was determined by MTT chromatometry. The rates of cell apoptosis were observed by ethidium bromide/acridine orange (EB/AO) of fluorescent light staining and flow cytometry,and the cell cycle was analyzed by flow cytometry. The expression of bcl-2,bax,caspase-3,glucose transporter 2 (GlUT-2),and pancreatic duodenal homeobox-1 (PDX-1) mRNA was tested by RT-PCR.Results After erythropoietin was treated in the cell culture,the neonatal porcine islet cells had normal morphology,function,and reaction of insulin secretion to the glucose stimulation. Cell count showed more cells in the experimental group than in the control group (P＜0.05). MTT chromatometry showed the optical absorbance tended to increase with time,and compared with the control group,the optical absorbance was higher in the experimental group (P＜0.05),the expression of PDX-1 mRNA was slightly up-regulated (P＜0.05). The expression of GLUT-2 mRNA had no difference in the 2 groups (P=0.34). In the experimental group,the apoptisis rate was lower than that in the control group by flow cytometry and EB/AO fluoscence staining (P＜0.01),and the expression of bcl-2 mRNA was higher. Howerer bax mRNA and caspase-3 mRNA were obviously lower than those in the control group (P＜0.01).Conclusion Erythropoietin can promote the proliferation but has no effect on the function of neonatal porcine islet cells in vitro. Erythropoietin can protect neonatal porcine islet cells from apoptosis through up-regulating bcl-2 mRNA and downreguling bax and caspase-3 mRNA.

All of the patients received the routine treatment, and the treatment group treated with XI additionally. The therapeutic effect was observed and plasma contents of inflammatory markers such as C-reactive protein (CRP), interleukin 6 (IL-6) and tumor necrosis factor ?(TNF-?) were detected before and after treatment.Results The effect of treatment group was better than that of the control group(P

[Objective] To observe the preventive effect and mechanism of heat-clearing and toxicity-removing therapy for the treatment of acute coronary syndrome (ACS), and to explore the relationship of ACS with inflammation. [Methods] Fifty five ACS patients were randomized into 2 groups:41 patients in group A were treated with Sanhuang Tablets (mainly composed of Radix et Rhizoma Rhei, Radix Scutellariae and Rhizoma Coptidis) p.o., 4 tablets one time, twice a day, and a routine treatment for anticoagulation, anti-platelet aggregation and anti-myocardial ischemia; 14 patients in group B were given routine treatment for anticoagulation, anti-platelet aggregation and anti-myocardial ischemia. The treatment course lasted 2 weeks. After treatment, improvement in symptoms such as chest pain, chest distension, short breath, palpitation, fever, spontaneous sweating, insomnia, lassitude, aversion to cold and cold limbs was compared between group A and group B by scoring method. Meanwhile, inflammatory indicators in the two groups were also observed before and after treatment. [Results] The decrease in symptom scores, as well as the decrease in blood C-reactive protein (CRP) , tumor necrosis factor a (TNF-?) and interleukin 6 (IL-6) , was obvious in group A than that in group B (P

Objective To investigate the efficacy of ablative fractionated erbium: yttrium aluminum garnet (Er: YAG) laser in facial acne scars and enlarged pores. Methods Forty-one patients with mild to moderate pitted acne scars and 23 patients with enlarged pores were treated with 81 (9 × 9) bits of facula for 3 to 5 sessions at an interval of 1 month. For acne scars, the pulse duration was medium to long, energy at 800 to 1200 mJ, and number of stacking passes 4 to 8; for enlarged pores, the pulse duration was medium, energy at 800 to 1000 mJ and number of stacking passes 2 to 4. The clinical improvement was evaluated by 2 blinded dermatologists. Meanwhile, the satisfaction rate was self-assessed by patients. Three-dimensional (3D) micro-topography imaging system was used to evaluate the improvement in surface roughness. Results The efficacy reached 82.93% and 86.96% for ache scars and enlarged pores, respectively. The satisfaction rate was 88.80% and 91.30% in patients with ache scars and those with enlarged pores, respectively. After treatment, the Ra and Rz values, as the indicators of roughness, decreased by 18.74% and 21.01%, individually (P < 0.001) in 11 patients including 6 with acne scars and 5 with enlarged pores. Conclusion Ablative fractionated Er:YAG laser can efficiently resurface pitted ache scars and shrink enlarged pores.

Objective To investigate the protective effect of green tea-based cream at different con- centrations on photoaging and photo-immunosuppression. Methods Twenty healthy female volunteers were enrolled into this study with informed consent. Green tea-based cream with a mass fraction of 2%-5% (pre- pared by adding green tea extracts to an emollient formulation), excipient or green tea extracts alone were applied to six unexposed sites on the back of these volunteers. Thirty minutes later, these treated sites were subjected to solar-simulated ultraviolet irradiation (ssUVR) with a 1.5-fold minimal erythema dose once a day for 4 days. At 6, 24 and 48 hours after the last irradiation, green tea-based cream were applied repeatedly to the corresponding sites. Biopsy specimens were obtained from the seven sites 72 hours following the last irradiation, and immunohistochemical staining was performed to detect cytokeratin 5/6 and 16 expression, as well as the densities of CDla- or HLA-DR-positive cells. Resttlts Green tea-based cream at a mass fraction of 2% to 3% could effectively prevent ssUVR-induced obvious erythema and hyperpigmentation. The posi- tivity (+) rates plus strong positivity (++) rates reached 50% and 25% for CK5/6 in the sites treated with ssUVR only and those irradiated and protected with green tea cream at a mass fraction of 3%, respectively, 69% and 31% in the sites treated with ssUVR only and those irradiated and protected with green tea-based cream at a mass fraction of 2%, respectively. Compared with the control site without irradiation or protec- tion, a decrease over 75% was noticed in the density of epidermal CD1a- or HLA-DR- positive Langerhans cells in the irradiated sites without protection, and green tea-based cream, especially those at a mass fraction of 3%, could effectively inhibit the density decrease. Conclusion Green tea extracts could effectively pro- tect skin from photoaging and photo-immunosuppression with the optimal mass fraction at 2% or 3%.

A method was developed for analyzing the stable carbon isotope ratio of five volatile components ( Ethanol, Glycerol, Acetic acid, Ethyl lactate, 2-methyl-butanol ) in wine using gas chromatography-combustion-isotope ratio mass spectrometer ( GC-C-IRMS ) . The sample injection volume was less than 0. 5 μL, and the analytical time of each run was less than 14 min. The precision of this method was 0. 08‰-0. 25‰ for analyzing standards, while 0. 09‰-0. 36‰ for wine samples. Compared to element analysis-isotope ratio mass spectrometry ( EA-IRMS) results, the deviations were lower than 0. 5‰. Fifty-four wine samples from France, Australia, America and China were considered. The δ13 C of five volatile components were measured using GC-C-IRMS. Discriminant analysis ( DA) was employed for analyzing the geographical origin traceability of selected wine. The result indicated that δ13 C of volatile components could be used to distinguish the origin of wines. The method was shown to be effective in improving detection of the origin traceability of wine.
