The incidence of allergic airway diseases has grown steadily in the past decade.Allergic rhinitis is closely associated with the development of asthma.Genetic and environmental factors are etiologically considered to be the main contributors to the development of allergic airway diseases.So far,overwhelming data from studies on humans and animals have indicated a systemic pathway linking the upper and lower airways.Neurogenic inflammation plays an important role in allergic airway diseases.This paper outlines the latest progress in the related researches.

Objective To assess the necessary excision of normal parenchyma tissue in nephron sparing surgery for renal cell carcinoma. Methods 102 specimens from radical nephrectomy for RCC were step sectioned at 3 mm intervals and examined.The tumor and field 20 mm beyond pseudocapsule were continuously sectioned and examined for completeness of pseudocapsule,the presence of micro multifocal carcinoma and for vascular and parenchyma invasion beyond pseudocapsule. Results 49 (48.0%) of the 102 specimens were void of intact pseudocapsule.The presence of extra pseudocapsule cancerous lesions was within 0～8 mm [(1.2?1.9) mm] beyone the capsule,with 30.4% of them within the field of 1～8 mm.with the statistic method of one side analysis of frequency,the percentile value of P97.5 and P100.0 was 7.4 and 8.0 mm respectively. Conclusions These data denote that when nephron sparing surgery is done for renal cell carcinoma,at least 10 mm of normal parenchyma tissue beyond the pseudocapsule should be excised with the tumor.The nucleation techniquc should not be encouraged.

0.4).ConclusionsThese data denote that biological behaviors and malignant features of multifocal tumors are very similar to those of primary ones.In addition,considering the significant relationship of multicentricity with vascular invasion and incompleteness of pseudocapsule of RCC,it is suggested that the secondary tumors might be more likely the result of intrarenal metastasis of the primary tumor rather than the results of multifocal genesis.

Objective To investigate the effect of psychological intervention, combined with Concentrated Tinidazole Gargles on dental plaque and gingivitis inflammation and influence factor of life quality in elder patients. Methods The control group was given Concentrated Tinidazole Gargles treatment, the research group was given psychological intervention on the basis of Concentrated Tinidazole Gargles (as control group). Plaque index, gingivitis index and SF-36 scale changes before and after treatment were recorded between two groups of elderly patients with gingivitis. Results There was no significant difference in plaque index, gingival indexand SF-36 score compared with before treatment between two groups; Plaque index, gingivitis index and the SF-36 score were improved in the research group better than the control group after treatment (P<0.05). Conclusion There is positive significance in improving the clinical efficacy of Concentrated Tinidazole Gargles plus psychological intervention and assurance of the quality of life on gingivitis in elder patients.

Objective To evaluate the efficacy of endoscopic injection hemostasis and sequential application of sandostatin in treatment of Dieulafoy's lesion. Methods After diagnosis of Dieulafoy's lesion confirmed, endoscopic injection hemostasis(EIH) together with mixture hypertonic saline and epinephrine(HSE) was performed, and then sandostatin was given consecutively for 7 days. The control group included the patients who were not given sandostatin or given just for 1 to 2 days. Results The rates of recurrent bleeding and transfer into surgery in sandostatin group were significantly lower than those in control group,(12.5% and 6.3% versus 53.8% and 46.2% respectively, P

At present, the theory and experiment teaching of forensic toxicology are faced with difficulties such as lake of practical cases and toxic types, content being abstract and difficult to un-derstand. On that account, we collected and collated many typical cases from Public Security Bureau and our school's medico legal expertise center, and then a relatively systematic and complete teaching case base in forensic toxicology has been constructed, and will be supplement constantly, so as to pro-vide extensive teaching resources and improve the teaching quality of forensic toxicology.

Objective To elucidate the clinical features and treatment of hemangiopericytomas (HPCs) in different parts of the body, especially in CNS. Methods Clinical data of 41 cases with HPC which were treated at 301 Hospital from 1993 to 2004 were retrospectively analyzed with a review of relevant literature. Follow-up periods ranged from 4 to 150 months after surgery (mean 34 months). Results Among 41 patients of HPC, 21 tumors (51.2%) were found in CNS, and the rest 20 (48.8%) in other systems. Thirteen tumors were diagnosed as malignant HPC. Surgery for tumor removal was performed in all 41 patients. Among the 62 operations, total removal of tumor was achieved in 49 cases and subtotal removal in 13 cases. Recurrence in original site of the tumor occurred 21 times (33.9%) in 14 patients. Five patients (12.1%) presented one or more distant metastasis, and 5 patients died. HPCs in CNS and in other systems displayed similar clinical characteristics and pathological morphology. Conclusions HPC is a rare angioneoplasm that may arise in any part of the body. It is a great challenge to neurosurgeons as well as other surgeons to surgically manage the tumor. HPC has an unfavorable prognosis because its high rate of recurrence and metastasis. HPC in CNS and in other parts of the body should be recognized as one disease. At the same time, HPC in CNS has its distinct features.

Objective To compare the difference of peripheral blood leucocyte percentages in malaria patients among Sysmex‐XE5000 ,CellaVisionDM96 and manual microscope classification ,and to verify the accuracy and reliability of the Sysmex‐XE5000 automatic blood corpuscle detection instrument for detecting the leukocyte classification in blood routine .Methods The leucocyte percentages data in 82 cases of malaria detected by using the Sysmex‐XE5000 in the Shenzhen Municipal Third People′s Hospital from January 2011 to December 2015 were retrospectively collected ;the peripheral blood smear in 82 cases of malaria obtained the percentages after the classification by the CellaVisionDM 96 ;then the peripheral blood smear was performed the leucocyte classifica‐tion by the manual microscopy for calculating the percentage .Results In the pairwise comparison of percentage obtained from the peripheral blood leucocyte classification by Sysmex‐XE5000 ,CellaVisionDM96 and manual microscopy ,only the monocytes percent‐age had statistical difference between CellaVisionDM 96 and manual microscopy (P<0 .05) ,the other differences had no statistical significance (P>0 .05) .Conclusion By comparing the peripheral blood leucocyte percentages data in malaria patients by Sysmex‐XE5000 ,CellaVisionDM96 and manual microscopic classification ,it is indicated that the leukocyte classification data by Sysmex‐XE5000 are accurate and reliable ,malaria parasite does not affect peripheral blood leukocyte classification ,but it is necessary to pay more attention to monocytes classification in CellaVision DM 96 classification .

Objective To systematically the effect of mindfulness-based stress reduction(MBSR) on improving perceived stress and sleep disturbance in cancer patients.Methods The databases of PubMed(Medline),Cochrane,BIOSIS Previews,Web of Science,CBM,CNKI,VIP and Wanfang Data were retrieved by computer,moreover the related journals and included reference literatures were retrieved by manual searching for finding the randomized controlled trials(RCTs) on the application of MBSR in perceived stress and sleep disturbance of cancer patients.Two reviewers independently screened the literatures according to the inclusion and exclusion criteria,extracted the data,and assessed the quality of RCTs.The meta analysis was conducted by adopting the RevMan 5.3 software.Results Nine RCTs involving 974 patients were included.The meta analysis results indicated that the improvement of perceived stress and sleep disturbance after intervention had statistical difference between the MBSR group and control group[MD=-4.63,95％CI(-5.10,-4.17),P＜0.01,MD=-2.18,95％CI (-2.35,-2.01),P＜0.01],but the difference after 3-month intervention between the two groups was not statistically significant.Conclusion The present evidences show that the MBSR method can relieve the perceived stress and sleep disturbance in cancer patients during a short period,but long term effect still needs to carry out more researches to be verified.
