Allergic rhinitis (AR)and bronchial asthma often coexist in the same individual,in which they influence development and severity of each other.Both domestic and foreign research has showed that Syn-ergistic treatment to children with AR and asthma could be achieved by inhaled corticosteroids(ICS),oral leu-kotriene receptor antagonist and subcutaneous /sublingual allergen specific immunotherapy;collaborative manage-ment will be realized by doctors'Comprehensive clinical assessment,children and caregivers'self-assessment and chronic disease management tools.Collaborative treatment and management is significant to children with both allergic rhinitis and asthma.In addition,it has an edge in improving compliance of children and their parents during the treatment,the quality of childrens'life,and reducing burden of the diseases.

Objective:To screen for the differentially expressed genes in peripheral blood mononuclear cells(PBMCs) from type 2 diabetes patients with distal symmetric polyneuropathy(DSPN) by gene microarray.Methods: A 5 075 gene cDNA microarray was used to examine gene expression in PBMCs of 2 type 2 diabetes patients with DSPN(group 1),2 type 2 diabetes patients without DSPN(group 2),and 2 age-and sex-matched controls(control group).The differentially expressed genes were identified and subjected to real-time RT-PCR analysis.Results: Twenty-two genes were found to be differentially expressed,including cell metabolism and signal transduction genes,oncogenes and anti-oncogenes,DNA synthesis and repair genes,ion channel and transport protein genes,DNA-binding,transcription and transcription factor genes,and cytoskeleton genes.There were 4 genes up-regulated and 18 down-regulated.Real-time RT-PCR results of AK1 and FBXO7 were consistent with that of microarray analysis.Conclusion: Microarray expression profile of PBMC in type 2 diabetes patients with DSPN is differential.DSPN may be involved in cell metabolism,signal transduction,DNA synthesis,etc.

BACKGROUND: During plasty of breast, innervation in nipple and areola of breast should be comprehended particularly in order to avoid sensory and motor disorder induced by nerve injury. OBJECTIVE: To observe the courser and distribution of nerve in nipple and areola of breast and provide anatomic data for plasty of breast. DESIGN: Single sampling study. SETTING: Department of Human Anatomy, Medical College of Qingdao University; Department of Pathology, Affiliated Hospital of Medical College of Qingdao University. PARTICIPANTS: The experiment was carried out in the Department of Human Anatomy, Medical College of Qingdao University and Department of Pathology, Affiliated Hospital of Medical College of Qingdao University from September 1999 to April 2001. Sixteen breasts of 8 adult female corpses aged 20-40 years and 10 breasts (5 right and 5 left) of 10 adult females with cancer of the breast aged 43-58 years were selected in this study. All patients or relations were consent. METHODS: ① Breast samples of 16 adult female corpses were scanned layers by layers with stereo anatomic micro scope to chase courser and distribution of nerve in subcutaneous fascia of mammary cancer. ② Ten fresh breast sam pies were frozen, cut into sections and stained with haematine-eosin. The typical transects were selected to observe dis tributed density of nerve fiber in 4 quadrants at various layers with stereology. MAIN OUTCOME MEASURES: ① Innervation in nipple and areola of breast,, ② numbers of nerve fiber of the same sample in various transects. RESULTS: ① Nerve which was distributed in nipple and areola of breast was derived from the lateral cutaneous branch and anterior cutaneous branch of the 3rd, 4th and 5th intercostal nerves and deep branch of mammary cancer. ② The lat eral cutaneous branch of the 4th intercostal nerves went into nipple and areola of breast with the directions like 4 o'clock in the left and 8 o'clock in the right, and nerves dominated nipple were derived from the lateral cutaneous branch of the 4th intercostal nerves. ③ Numbers of nerve fiber in extra-inferior quadrant of nipple and areola of breast were more than those in intra-superior, intra-inferior and extra-superior quadrants (8.06±0.18, 4.63±0.14, 4.43±0.16, 2.13±0.11, P ＜ 0.01). ④ Density of innervation in nipple and areola of breast was decreased centripetally. CONCLUSION: Operation of chest, especially plasty of breast, had better not damage lateral cutaneous branch and ante rior cutaneous branch of the 3rd, 4th and 5th intercostal nerves. Extraordinarily, the lateral cutaneous branch of the 4th inter costal nerves and nerve in extra-inferior quadrant of nipple and areola of breast should be protected carefully in order to avoid sensory disorder.

Objective To explore the variance of helicobacter pylori(Hp) infection rate in children with recurrent abdominal pain(RAP).Methods By using the()~(13)C-urea breath test(~(13)C-UBT) to detect the status of Hp infection in 1676 children with RAP from 1998 to 2004.Results 1.Total 1676 cases of children with RAP were detected.There were 438 cases showed Hp positive,the positive rate was 26.13%.The infection rates in patients from 2-5,5-10,and 10-14 years of age were 23.66%(84/355),(26.31%)(286/1087),29.06%(68/234),respectively.2.Hp infection rates in children with RAP from 1998 to 2004 were 29.33%(83/283),(28.90%)(76/263),25.76%(51/198),26.01%(56/215),25.81%(48/186),24.45%(67/274),22.18%(57/257),respectively.Conclusion 1.The Hp infection rate in children with RAP increased with age;2.The Hp infection rate in children with RAP decreased year after year.

Objective: To explore the effect of 5-Aza-2′ -deoxycytidine (5-Aza-CdR) on ERα expression, proliferation and invasion of human breast cancer cell line MDA-MB-231. Methods: The breast cancer cell line MDA-MB-231 was treated with 5-Aza-CdR. The effect of 5-Aza-CdR on proliferation was evaluated by MTT assay and cell growth curve was drawn. The cell cycle was analyzed by flow cytometry. Immunohistochemistry and RT-PCR were used to determine the changes of ERα expression and matrix metalloproteinase-2 (MMP-2) expression in the MDA-MB-231 cell after 5-Aza-CdR treatment. The invasion ability of MDA-MB-231 cells was tested by Boyden chamber assay. Results: Compared with the control, the cell growth speed was significantly slowed down and the cell cycle was arrested at G0/G1 phase after 5-Aza-CdR treatment. The expression of ERα gene was partly restored in ERα-negative human breast cancer MDA-MB-231 cell after 5-Aza-CdR treatment. The expression of MMP-2 in MDA-MB-231 cells was down-regulated and the invasion ability of MDA-MB-231 cell was decreased after 5-Aza-CdR treatment. Conclusion: 5-Aza-CdR treatment effectively inhibited cell proliferation, induced cell cycle arrest, and decreased cell invasion ability of breast cancer MDA-MB-231 cells. The findings suggested that the partial restoration of ERα expression and the decrease in MMP-2 expression may be one of the mechanisms for the biological behaviour changes of MDA-MB-231 cells induced by 5-Aza-CdR.

This study was aimed to find the optimal conditions for seed propagation of Fritillaria cirrhosa in the plateau region in order to summarize the best sowing time and method of artificial propagation. Seeds were stored in appropriate environment. After the seeds matured, the seedbed of F. cirrhosa was treated with cattle dung humus and small shed. The results showed that early March is the best sowing time and cattle dung humus with a thickness about 1 cm is the best coving for propagation of F. cirrhosa; the growing period of film propagation (FP) is about 160 days each year compared with that of control about 50-60 days, respectively. It was concluded that the propagating seeds in plastic greenhouses by using cattle dung humus as planting substrates, using sunshade nets for shading and keeping humidity by spraying can effectively prolong the growing period, improve the retention rate of annual bulbs and the production of F. cirrhosa.

OBJECTIVE: To investigate the effects of Gypsum Fibrosum and Gypsum Fibrosum Preparatum in promoting granulation. METHODS: The wounds of muscle layer were produced in rats by using surgical operation. Two round wounds, with diameter about 1.5 cm, were cut at the depilatory area of two sides of the back of each rat, with an interval of 2 cm, deep to muscle layer, and the thickness of the knife wound of muscle layer was about 0.15 cm. Forty SD rats with the wounds were randomly divided into 4 groups: untreated group, beifuji-treated group, Gypsum Fibrosum-treated group and Gypsum Fibrosum Preparatum-treated group, with 10 rats in each group. Then the wounds were sprinkled with powders of Gypsum Fibrosum and Gypsum Fibrosum Preparatum, or sprayed with beifuji solution, respectively. The healing state of granulation tissues of the wounds was observed at the eighth and fourteenth day respectively. RESULTS: The number of fibroblasts, the number of capillary tubes and the area of capillary tubes in granulation tissue of wounds in the Gypsum Fibrosum Preparatum-treated group were significantly higher than those in the untreated group and Gypsum Fibrosum-treated group (P<0.01). There were no statistical differences between the Gypsum Fibrosum Preparatum-treated group and the beifuji-treated group. However, Gypsum Fibrosum-treated group showed no obvious differences compared to the untreated group (P>0.05). CONCLUSIONS: Gypsum Fibrosum Preparatum can accelerate the formation of collagenoblast and micrangium in wounds, and the proliferation of granulation tissues, thus promoting the skin wounds to healing. The effect of Gypsum Fibrosum is changed after being calcined, and Gypsum Fibrosum Preparatum has obvious effect in promoting granulation.

Objective To evaluate the effectiveness of periodontal mechanical therapy on periodontal health and interleukin-6 (IL-6) levels in gingival crevicular fluid (GCF) in type 2 diabetic patients with chronic periodontitis. Methods GCF samples were obtained with filter papers in first molar sites from 37 type 2 diabetic patients with chronic periodontitis. The randomized controlled and blinded clinical trial with a duration of six months was designed to compare effects between three groups of professional mechanical tooth cleaning (PMTC), i.e. coronal scaling (group Ⅱ) with periodontal initial therapy (group Ⅰ) and without clinical therapy (control group). The clinical periodontal index such as probing depth (PD), attachment loss (AL), modified bleeding index (mBI) and bacteria plaque index (PLI) were obtained with a Williams type periodontal probe. Laboratory examination including GCF volume, concentrations and total amounts of IL-6 in GCF were detected with ELISA method. Results Significantly decreasing trends of PD, AL, mBI, GCF volume and total amounts of IL-6 were observed in group Ⅰin all test period. The group Ⅱ had a significant reduction of PD at the third month as compared with baseline (⊿=0.36 mm, P＜0.05), and the other figures showed descending trends but didn′t present statistical significances. At the end of study, the group Ⅰand Ⅱ had significant reductions of GCF volume compared with increases of control group (0.96 μ1＞0.03 μ1mm＞-0.20 μ1, P＜0.05). Conclusions The sequential periodontal supra- and sub- gingival scaling has definitive effects on periodontal health improvement and on reducing the IL-6 level in GCF in type 2 diabetic patients.

Fifty-two patients exactly diagnosed as rheumatoid arthritis in the active stage in clinic were treated by acupuncture plus western medicine. Thirty days made up a course of treatment. There were significant differences in clinical symptoms, signs, and immunological indexes between pretreatment and posttreatment (P<0.05, P<0.01). The treatment of rheumatoid arthritis in the active stage by acupuncture plus western medicine could effectively regulate humoral immunity and enhance the clinical therapeutic effect.

Objective To investigate the treatment methods for primary gastric lymphoma (PGL) and analyze the prognostic factors.Methods The clinical data of 55 patients with PGL who were admitted to the First Affiliated Hospital of Dalian Medical University from July 2002 to December 2007 were retrospectively analyzed.Operation,medication or operation combined with medication were applied to patients according to the pathological type,clinical staging,infection of helicobacter pylori and complications.Patients were followed up via phone call till February 2013,and the location,diameter,pathological type,clinical stage of the PGL and the treatment methods were recorded for prognostic analysis.The survival rate was calculated by Kaplan-Meier method,and the univariate analysis of survival was done by Log-rank test.Multivariate analysis was done by COX regression model.Results The PGL located at the gastric antrum in 26 cases,body of the stomach in 17 cases,fundus of the stomach in 5 cases,gastric cardia in 3 cases,body and antrum of the stomach in 4 cases.There were 46 patients with ulcerous PGL,5 with nodular PGL and 4 with diffused and infiltrated PGL.There were 53 B cell lympboma,1 T cell lymphoma and 1 undefined tumor.Of the 53 patients with B cell lymphoma,36 were with mucosa-associated lymphoid tissue lymphoma (MALTL) and 17 with diffuse large B-cell lymphoma (DLBCL).There were 23 patients in stage Ⅰ,23 in stage Ⅱ,4 in stage Ⅲ and 3 in stage Ⅳ.Of the 55 patients,23 received operation,14 received medication,17 received operation + medication,and 1 left untreated.Fifty-three patients had complete follow-up data.The median time of follow-up was 60 months (range,7-132 months).The 1-,3-,5-year cumulative survival rates were 91％,79％ and 72％.The results of univariate analysis showed that tumor diameter,pathological type and clinical staging were risk factors influencing the prognosis of PGL patients (x2 =9.34,6.59,88.01,P ＜ 0.05),while the treatment methods did not influence the prognosis of PGL patients (x2 =3.63,P ＞ 0.05).The results of multivariate analysis showed that DLBCL,clinical stages Ⅲ and Ⅳ were independent risk factors influencing the prognosis of PGL patients (OR =5.758,2.231,95％ confidence interval:2.536-13.073,1.370-3.625,P ＜ 0.05).Conclusion Multi-disciplinary team treatment should be recommended for PGL patients.Pathological type (DLBCL) and clinical stages (stage Ⅲ and Ⅳ) are the independent risk factors influencing the prognosis of PGL patients.
