OBJECTIVE:
Understand the main types and characteristics of inhaled allergens in allergic rhinitis patients in Urumqi, Xinjiang, and provide theoretical basis for diagnosis, treatment, prevention of local allergic rhinitis and epidemiological investigation.
METHOD:
Inhaled allergen detecting on suspected patients with allergic rhinitis in clinic by the allergopharma skin prick test. Group the skin prick test positive patients of 340 samples according to their nationality, age and gender, then compare the inhaled allergen differences between them.
RESULT:
The total positive rate with allergic rhinitis prick test in 340 cases is 94.7%, of which the highest proportion is Artemisia (66.2%), followed by Chenopodium album (51.2%), poplar (42.6%), Ulmus (40.9%), Liu (33.8%), Timothy (27.6%), dust mite (21.2%), house dust mite (17.9%), ragweed (15.9%), dog (11.2%), cat (10.6%), cockroach (8.5%), Alternaria (5.6%) and Candida albicans (3.5%). The sensitivity of poplar, willow, Timothy and Alternaria of the minority group is higher than the Han group (P<0.05). The allergen positive rate difference among different age group has statistical significance (Χ2=59.076, P<0.01).
CONCLUSION
Artemisia, Chenopodiaceae, poplar and elm are the main allergens in Urumqi area. There is a difference in allergen sensitivity between Minority and Han nationality patients. There is no statistical significance on inhaled allergen positive rate between different genders. Specific allergens can provide basis for the prevention and control of allergic diseases in Urumqi area.

Objective: To explore the application value of ablation catheter for pacemaker atrial lead restoration in relevant patients.
Methods: A total of 6 patients with atrial lead dislodgement after pacemaker implantation were selected for our study. The atrial lead restoration was conducted by using ablation catheter via femoral vein pathway.
Results: The average operational time was (15.0 ± 3.7) min which was obviously less than traditional operational time. The position of electrode restoration was ideal with well immobilization.
Conclusion: Ablation catheter is feasible for arial lead restoration in patients with atrial lead dislodgement after pacemaker implantation.

Objective:To study the drug distribution in the local tissues and lymph nodes treated with targeting and continuous interstitial chemotherapy for the oral squamous cell carcinoma before operation. Methods:8 patients with oral squamous cell carcinoma were treated by implanting the sustain-released cisplatin around and into the primary lesion. Drug distribution in tissue were studied by the graphite furnace atomic absorption spectrometry. Results:The drug concentration in the center of the tumor,1 cm and 2 cm from the tumor fringe were (34.877 1?15.720 8),(20.690 0 ?15.688 6) and (6.635 7?3.862 3) ?g/g, respectively. The drug concentration within lymph nodes of the sub-mental and submandibular area, deep cervical lymph nodes for the upper,middle and lower were(2.991 4?3.055 7),(4.026 0 ?3.692 0), (7.192 0 ? 8.958 7) and (5.028 5?3.484 3)?g/g, respectively. Conclusion:Targeting and continuous interstitial chemotherapy for the oral squamous cell carcinoma by implanting sustain-released cisplatin can increase drug concentration in the local tissues and the lymph nodes, to attain good efficacy of targeting chemotherapy.

Objective To explore the relationship between the red cell volume distribution width (RDW)in patients with ges-tational diabetes and insulin resistance(IR).Methods A total number of 160 pregnancies performed in Guangzhou Women and Children’s Medical Center from January to October 2016.Matching 80 patients with gestational diabetes (the GDM Group)with 80 healthy pregnancies according to their age,gestational weeks and times.Their inflammatory parameters (hs-CRP,neutrophil-to-lymphocyte ratio,RDW)were respectively examined.HOMA-IR was calculated by testing the level of FBG and FIns.The association of the red cell volume distribution width with insulin resistance was analyzed.Results The level of four inflammatory parameters (hs-CRP,WBC,neutrophil-to-lymphocyte ratio,RDW)were significantly higher than that the control group (t=5.695,5.232,3.337,7.814,all P<0.01).Pearson correlated analysis suggested that RDW had positive correlation with HOMA-IR (r=0.58,P<0.01).Conclusion The RDW level were elevated in the GDM patients and had positive correlation with HOMA-IR,which indicated that IR was associated with inflammation and provided proof to research mechanism of GDM.

Objective To explore the role and the possible molecular mechanisms of natural anti-oxLDL IgM monoclonal antibody played and involved in pathogenesis of atherosclerosis. Methods Natural anti-oxLDL IgM monoclonal antibody 3A6 was generated by using standard hybridoma production techniques. Influence of 3A6 on formation of foam cells was observed by Oil Red O staining and affinity of Na125I-conjugated oxLDL on the naive and LPS-activated macrophages. After LPS stimulation on macrophages, anti-TLR4 neutralizing mAb, p38MAPK specific inhibitor SB203580, NF-kB specific inhibitor PDTC or RNAi targeting Fcα/μ receptor (Fcamr) were applied, respectively. Results Natural anti-oxLDL IgM monoclonal antibody 3 A6 were found specifically inhibit the binding of CuoxLDL to naive macrophages but not the binding of CuoxLDL to LPS-activated macrophages. It also promoted the formation of CuoxLDL-mediated foam macrophages. 3A6 F(ab')2 or pre-incubation with un-related IgM inhibited the binding of 3A6/CuoxLDL complex to LPS-activated macrophages. LPS up-regulated the expression of Fcamr in macrophages in a dose- and time-dependent manner, which was attenuated by treatment with anti-TLR4. LPS induced the phosphorylation of p38MAPK and translocation of NF-kB p65, contributing to the up-regulated expression of Fcα/μ receptor in macrophages. Conclusions Natural anti-oxLDL IgM monoclonal antibody 3A6 specifically inhibited the binding of CuoxLDL to naive macrophages in vitro. However, LPS, through the Toll-like receptor (TLR)4 receptor, activated the p38MAPK and NF-kB pathways and up-regulated the expression of Fcα/μ receptor in macrophages, which promoted the binding of 3A6/CuoxLDL complex to macrophages through binding with Fc fragments and the formation of foam macrophages. Therefore, our findings provide a new explanation why bacterial infection deteriorates the pathogenesis of atherosclerosis.
