Objective:To investigate whether susceptibility or resistance to allergic rhinitis associated with HLA-DRB alleles.Method:Using PCR-SSP (sequence-specific primer polymerase chain reaction),we tested the frequency distribution of HLA-DRB alleles in 41 patients with allergic rhinitis (AR) and 41 healthy controls from Beijing China.Result:The frequence of HLA-DRB10301.2 and HLA-DRB 40101 was lower in AR than in controls (2.44% vs 17.07%, P＜0.05;29.27% vs 51.22%, P＜0.05).Conclusion:HLA-DRB10301.2 and HLA-DRB 40101 alleles might confer protection against AR.

With the development of breast-conserving surgery,the problem of local relapse after conservation therapy became a hot spot for discussion.There was much research done on the influential factors of recurrence after conservation therapy,however,there is little research on the strategy for salvage of relapse.This review summarizes the recent research on the diagnosis,treatment and prognosis of local recurrence of breast cancer after conservation therapy.

This article discussed the ancient and modern meaning of security of intense drugs for pregnant woman. And emphatically studied the meaning of the ‘gu’, pointing out that ‘gu’had three connotations, one referred to disease, second mean the original disease, with the ‘new’disease relative, the third referred to reasons. In addition, the article expounded how can be safe for the pregnant woman to use drugs with extremely intense action. In this paper, its purpose was to examine how to achieve security under circumstance of sick and fi nally achieve balance and harmony.

Pathogenesis is the nucleus of diagnosis and treatment in TCM, this article has reviewed about the research on pathogenesis in TCM, summed up the research results, especially given the analysis on that. It proposes that deeper research would be done on defining the concept and connotation of pathogenesis, clarifying the relation between pathogenesis and syndrome differentiation, and establishing the core states about pathogenesis and so on.

Objective　To explore the correlation between the expression of p33/ING1 and the clinicopathological features in patients with colorectal cancer, and to understand the possible mechanism of p33/ING1 in the oncogenesis of colorectal neoplasms. Methods　All samples of normal mucosa and cancer tissues from 52 patients with colorectal cancer were detected for their expression levels of p33/ING1 by RT-PCR. Results　A significant decrease in p33/ING1 mRNA expression was found in 30 out of 52(57.7%) colorectal cancer tissues. The results also showed that repression of p33/ING1 expression markedly related to both the Duke's stage and metastasis. Conclusion　Down-regulation of p33/ING1 may play an important role in the oncogenesis and development of colorectal carcinoma.

OBJECTIVE In order to study the effect of inhalable particles on evocation of allergic rhinitis in rats and its possible mechanism. METHODS The experimental group rats were basically allergized with OVA from intraperitoneal injection. Three groups were provoked by OVA alone, PM10 plus OVA and PM10 alone through nasal cavity respectively. The Control Group was allergized by NS instead of OVA, while the method of provocation was the same as experimental group. Then, the rats were sacrificed 24 hours after the last provocation. The morphological changes of the rats' nasal mucosa were observed by scanning electron microscope and hematoxylin-eosin (HE). The number of the eosinophile of the rats' nasal mucosa was counted under HE staining. RESULTS The amount of eosinophile in the three experimental groups was significantly different from that in NS group, and there was also a significant difference among three experimental groups. The amount of eosinophile in PM10 plus OVA group was obviously higher than that in other groups. Observed by scanning electron microscope, the cilia of the epithelium of the three experimental groups were significantly reduced, fallen off, fallen down, got enlaced, and adhered by secretion. CONCLUSION In the period of provoking, the inhalable particles may play a synergic role with allergen, and it can aggregate the rats' nasal mucosa injury and the allergic inflammation.

Objective To understand the risk factors of allergic rhinitis in adults. Methods Using 1:1 paired matching case-control study design, 100 pairs of adults allergic rhinitis patients and the relevant controls from the E.N.T. department of Renmin Hospital of Peking University were recruited. Cases and controls were interviewed face to face using a designed health questionnaire in which the general social demographic characters, disease history, smoking history, occupation, indoor environmental situation and family genetic history were included. The questionnaires were analyzed by signal and multiple regression model of SPSS software. Results Allergic rhinitis was associated with the pollen allergic history (OR=2.04,95%CI: 1.31-3.20), occupational exposure to dust was a risk factor of allergic rhinitis (OR=1.46, 95%CI:0.83-2.57), the mother allergic rhinitis history could increase the risk of their off-springs suffering from allergic rhinitis(OR=2.05, 95%CI:1.03-4.07) and keeping ventilation could significantly decrease the risk suffering from allergic rhinitis(OR=0.70, 95%CI:0.34-1.18). Conclusion The occupational dust exposure, pollen allergy and mother allergic rhinitis history are related to allergic rhinitis in adults. Keeping ventilation may be a protective factor of allergic rhinitis in adults.

ObjectiveTo study the expression of ING1 mRNA and its mutation status in human colorectal cancer. MethodsSamples of normal mucosa and cancer tissues from 52 patients with colorectal cancer were detected for their expression of ING1mRNA with RT PCR, and screened for its mutation with PCR SSCP. The expression of p53 protein was detected with immunohistochemical staining.ResultsThe impaired expression of ING1mRNA in colorectal cancer was associated with an advanced Dukes′ stage and metastasis of lymph nodes ( P ≤ 0 01). The expression of ING1mRNA positively correlated to that of p53 protein ( P ≤0 01). And a infrequent mutation of ING1 was also observed. Conclusion Our results suggest that ING1 contributes to the tumorigenesis and progression of colorectal cancer through down regulating its expression rather than through mutation.

All patients were treated with Zhong Yan No. 2 Prescription, 3 months constituting one course. Indexes of immunologic functions before and after treatment were compared and HIV -Rt - PCR detection was made in 16 cases. Results indicated that in absolute number of CD4, 8 cases increased, 14 cases decreased and 7 cases did not change; in CD4/CD8 ratio, 2 cases increased, one case decreased and 16 cases did not change; Two cases had increase of both CD4 and CD4/CD8 ratio: 4 cases had a decrease of new pterin, 11 cases increased and one case no change; 6 cases had a decrease of HIV - Rt - PCR, 8 cases increased and 2 cases no change. The total effective rate was 48.28% based on comprehensive assessment of virus, immunity, body weight and symptoms.

Objective To observe the clinical efficacy and adverse reactions of intensity modulated radiotherapy (IMRT) combined with cisplatin for patients with carcinoma of cervix.Methods One hundred patients with carcinoma of cervix were randomly divided into 2 equal groups to undergo IMRT only (IMRT group)and IMRT combined group (IMRT with cisplatin chemotherapy group),with 50 cases in each.Both groups were treated with external intensity modulated radiotherapy,with the total dose of 50 Gy,2 Gy/fraetion,25 fractions in total,and 5 times/week.Two weeks later,internal radiotherapy followed,with the total dose of 42-48 Gy,1 time/week with 6-8 times and 6-7 Gy/fraction.When the internal radiotherapy began,the external radiotherapy stopped immediately.The combination group was treated concurrently with cisplatin given by intravenous drip once a week,at the dose of 30-40 mg/m2 body surface area for 4-5 weeks,and with total cisplatin dosage of 50-65 mg.Follow-up was conducted for 18 months(3-60 months).The 1-,3-,and 5-year survival rates,local control rate,distant metastasis rate,and disease-free survival rate,blood test,rectum,and bladder were observed.Results The 1-year survival rate,local control rate,distant metastasis rate,and disease-free survival rate did not differ significantly between these 2 groups,however,the 3-and 5-year survival rates,local control rates,distant metastasis rates and disease-free survival rates of the combination group were all significantly better than those of the IMRT group (x2 =3.843,4.336,4.336,4.960,P ＜ 0.05 ; x2 =3.934,4.454,4.000,4.244,P ＜0.05).The incidence rates of radiation proctitis and leukopenia of the combination group were significantly higher than those of the IMRT only group (x2 =4.110,4.320,P ＜ 0.05),whereas the incidence rates of cystitis,anemia,and thrombocytopenia were not significantly different between these 2 groups.No serious grade 3-4 proctitis and cystitis were observed in these 2 groups.Conclusions The IMRT combined with cisplatin chemotherapy shows higher 3-year and 5-year long-term efficacy in the patients with carcinoma of cervix than IMRT only group.
