Objective: To evaluate the effectiveness of family interventions among children with allergic rhinitis receiving immunotherapy, so as to provide insights into improvements of allergic rhinitis treatment. Methods: A total of 80 children with allergic rhinitis admitted to The First People's Hospital of Linping District from July 2018 to July 2021 were enrolled and randomly assigned into the control and intervention groups, of 40 participants in each group, and all children underwent immunotherapy. Children in the control group received routine interventions, while participants in the intervention group were given family interventions for 3 months, including health education, psychological counseling, and periodical follow-up. Parental awareness of allergic rhinitis was investigated using self-designed questionnaires, and the compliance to immunotherapy was evaluated. The clinical symptoms were evaluated using the symptom scores and the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), and the prognosis was evaluated using the Sino-Nasal Outcome Test-20 (SNOT-20). Results: There were no significant differences between the intervention and control groups in terms of gender, age, course of disease or disease severity (P>0.05). The scores for parental awareness of etiology [(9.56±0.25) vs. (7.45±0.85)], inducement factor [(8.84±0.62) vs. (6.76±1.36)], medication management [(9.56±0.25) vs. (7.97±0.85)] and daily life management of allergic rhinitis [(9.14±0.55) vs. (8.14±0.46)] were significantly higher in the intervention group than in the control group (P<0.05). The proportion of participants' compliance to immunotherapy was significantly higher in the intervention group than in the control group (92.50% vs. 75.00%, P<0.05). The scores for clinical symptoms [(3.12±0.94) vs. (3.96±1.23)], RQLQ score [(3.31±0.87) vs. (3.87±1.02)] and the SNOT-20 scores for nasal symptoms [(6.54±2.14) vs. (8.22±2.45)], sleep disorders [(4.11±0.58) vs. (5.24±1.03)], associated symptoms [(5.29±1.52) vs. (6.34±2.01)] and emotional consequences [(7.52±1.85) vs. (9.19±2.69)] were significantly lower in the intervention group than in the control group post-interventions (P<0.05). Conclusion Family interventions are effective to improve the compliance to immunotherapy, clinical symptoms, prognosis and quality of life among children with allergic rhinitis

Objective To investigate the effects of dexmedetomidine preconditioning on ischemia-reperfusion(I/R) injury to isolated rat hearts.Methods Twenty-four male Wistar rats weighing 230-260 g were anesthetized with intraperitoneal 10％ chloral hydrate 400 mg/kg and heparin 500 IU/kg.Their hearts were excised and perfnsed in a Langendorff apparatus with K-H solution saturated with 95％O2-5％CO2 at 37 ℃.Twenty-four isolated rat hearts were randomly divided into 3 groups after 10 min of equilibration(n =8 each):group I/R,dexmedetomidine 0.23,2.30 ng/ml preconditioning group (groups D I,D Ⅱ ).In group I/R,the hearts were perfused continuously for another 30 min.In groups D Ⅰ and D Ⅱ,the hearts were perfused with K-H solution containing dexmedetomidine 0.23,2.30 ng/ml for 20 min followed by 10 min washout before ischemia.All hearts were subjected to 30 min of global ischemia followed by 120 min of reperfusion with K-H solution.The activities of creatine kinase(CK) and lactate dehydrogenase(LDH) in coronary effluent were measured at the end of 10 min equilibration(balance),and at 5,30,60 and 120 min of reperfusion.Myocardial tissues were obtained at the end of reperfusion for determination of the activity of SOD and the content of MDA.Results Compared with group I/R,the CK and LDH activities in coronary effluent and MDA content in myocardium were significantly decreased,the SOD activity was significantly increased in groups D I and D Ⅱ ( P ＜ 0.05).Compared with group D Ⅰ,the CK and LDH activities in coronary effluent and MDA content in myocardium were significantly decreased,the SOD activity was significantly in group DⅡ ( P ＜ 0.05).Conclusion Dexmedetomidine preconditioning can attenuate myocardial I/R injury in a concentration-dependent manner in rats.

OBJECTIVE:To investigate the characteristics of adverse drug reactions (ADR) caused by quinolones in our hospital and to promote their rational use in clinic. METHODS: By a retrospective review,a total of 199 quinolones-induced ADR cases collected from May 2004 to December 2007 in our hospital were analyzed statistically in respect of patients' gender and age,drug species involved,past ADR history,route of administration,clinic manifestations,etc. RESULTS: A total of 9 kinds of quinolones involved in the 199 ADR cases,of which,118 cases were induced by levofloxacin,16.1% had past ADR history,93.5% of the ADR cases were induced via intravenous drip,and most common presentations of the ADR were lesions of skin and its appendants as well as digestive system. There were 7 serious ADR cases. CONCLUSION: The indications of quinolones should be controlled strictly,which should be preferably administered orally and monitoring of its administration should be emphasized in clinical practice to decrease and avoid the occurrence of ADR.

Objective To probe the advantages of BTX-A for the treatment of axillary hyper-hidrosis. Methods 42 cases were treated by BTX-A injection, 50 units per axillae, 25 sites with 2 u-nits each, 1.5 cm apart. They consisted of 24 cases of axillary hyperhidrosis, 10 cases of axillary hy-perhidrosis combined bromidrosis, and 8 cases of bromidrosis. Results All hyperhidrosis patients a-chieved good effects. Among patients with axillary hyperhidrosis combined bromidrosis, it had effects on hyperhidrosis, but only one case effected on bromidrosis. Among patients with bromidrosis, only one case had effect. Conclusions In the treatment of hyperhidrosis, BTX-A is very useful, and side effect is temporary and slight. But for bromidrosis, BTX-A is not very useful.

Objective To study the cytotoxic activity of Chinese compound prescription (Xiaozheng Yiliu Decoction) combined with cisplatin on human ovarian cancer OVCAR/DDP cells and its molecular mechanism. Methods The xenograft model was established by injection of OVCAR/DDP cells. Forty nude mice were randomly allocated into four groupsincluding control group, cisplatin treatment group, low-dose Xiaozheng Yiliu plus cisplatin treatment group,and high-dose Xiaozheng Yiliu plus cisplatin treatment group.The apoptosis was determined by TUNEL analysis.The survivin expression was detected by RT-PCR analysis.Results The inhibit rates in cisplatin treatment group, low-dose Xiaozheng Yiliu plus cisplatin treatment group,and high-dose Xiaozheng Yiliu plus cisplatin treatment group,were(5.56±1.14) ％,(18.42±7.73) ％,and (31.59±12.58) ％,respectively,and there were significant differences among the groups(F=8.64,P＜0.01 ).The TUNEL analysis showed that the percentages of cell apoptosis were(2.35±1.04) ％,(4.56±1.61) ％,(12.42±3.68) ％,(21.59±5.17) ％ in four different groups,respectively.After treated by Xiaozheng Yiliu Decoction,the mRNA expression of survivin was found to be down-regulated by RT-PCR analysis. Conclusion Xiaozheng Yiliu Decoction could iucrease the cytotoxic activity of cisplatin on ovarian cancer OVCAR/DDP cells, which may be related to the down-regulation of survivin gene expression.

BACKGROUND:Numerous studies have confirmed that neovascularization plays an important role in the growth, invasion and metastasis of tumors. OBJECTIVE:To investigate the features of CD133+ ovarian cancer stem-like cels differentiating into vascular endothelial cels. METHODS:CD133+ ovarian cancer stem-like cels were successfuly harvested from A2780 ovarian cancer cel lines using serum-free culture method, and incubatedin vitro onto 96-wel plates with or without Matrigel. Then, we observed the capacity of CD133+ ovarian cancer stem-like cels and human umbilical vein endothelial cels to form tube-like structures at different time points. Through xenograft experiments, the role of CD133+ ovarian cancer stem-like cels in the angiogenesis of ovarian cancer was observed using immunofluorescence staining. RESULTS AND CONCLUSION:CD133+ovarian cancer stem-like cels and human umbilical vein endothelial cels cultured with no Matrigel had no corresponding lumen formation, and could not express CD31. But those cultured with Matrigel had lumen formation and expressed CD31 significantly. After tumor formation, human-derived CD31 expression was observed in the tumors. These findings indicate that CD133+ ovarian cancer stem-like cels can differentiate into vascular endothelial cels, and be involved in tumor revascularization.
