ABSTRACT
Objective:To investigate the efficacy of Yupingfeng granule combined with cetirizine in the treatment of allergic rhinitis and its effects on serum inflammatory factor level. Methods:A total of 162 patients with allergic rhinitis admitted to Zhejiang Provincial Hospital of Chinese Medicine from January 2021 to March 2022 were included in this prospective controlled study. They were randomly divided into a control group and an observation group ( n = 81/group). The control group was treated with cetirizine and the observation group was treated with Yupingfeng granule combined with cetirizine. All patients were treated for 4 weeks. Clinical efficacy was compared between the two groups after 4 weeks of treatment. Main symptom score, nasal function indexes (total nasal airway resistance, nasal minimal cross-sectional area, and 0-5 cm nasal cavity volume), levels of inflammatory factors (interleukin-4, interleukin-6, and interleukin-10), and Rhinoconjunctivitis Quality of Life Questionnaire scores were compared between the two groups before and after 4 weeks of treatment. Results:Total response rate in the observation group was significantly higher than that in the control group [92.59% (75/81) vs. 79.01% (64/81), χ2 = 6.13, P < 0.05]. After 4 weeks of treatment, the scores of nasal congestion, nasal itching, and sneezing in the observation group were (0.63 ± 0.20) points, (0.70 ± 0.21) points, and (0.54 ± 0.17) points, which were significantly lower than (1.07 ± 0.23) points, (1.08 ± 0.24) points, and (0.89 ± 0.22) points in the control group ( t = 12.99, 10.72, 11.33, all P < 0.05). After 4 weeks of treatment, total nasal airway resistance in the observation group was significantly lower than that in the control group [(0.17 ± 0.05) kPa·s -1·L -1vs. (0.26 ± 0.06) kPa·s -1·L -1, t = 10.37, P < 0.05]. Nasal minimal cross-sectional area and 0-5 cm nasal cavity volume in the observation group were (0.94 ± 0.17) cm 2 and (9.74 ± 0.89) cm 3, respectively, which were significantly higher than (0.76 ± 0.10) cm 2 and (8.43 ± 0.78) cm 3 in the control group ( t = 8.21, 9.96, both P < 0.05). After 4 weeks of treatment, serum levels of interleukin-4 and interleukin-6 in the observation group were (67.79 ± 9.94) ng/L and (6.74 ± 1.42) ng/L, respectively, which were significantly lower than (104.31 ± 14.45) ng/L and (10.29 ± 2.56) ng/L in the control group ( t = 18.74, 10.91, both P < 0.05). Serum level of interleukin-10 in the observation group was significantly higher than that in the control group [(17.97 ± 2.54) ng/L vs. (12.48 ± 2.46) ng/L, t = 13.97, P < 0.05]. After 4 weeks of treatment, Rhinoconjunctivitis Quality of Life Questionnaire score in the observation group was significantly lower than that in the control group [(27.43 ± 8.82) points vs. (38.95 ± 7.76) points, t = 8.82, P < 0.05). Conclusion:Yupingfeng granule combined with cetirizine is highly effective on allergic rhinitis. The combined therapy can reduce clinical symptoms and inflammatory reactions, improve nasal function, and thereby improve quality of life.
ABSTRACT
Laboratory diagnosis is the main contents of diagnostics course for clinical majors,whose contents is too broad and too difficulty to understand.For this reason,the results of traditional teaching method are not satisfactory.Therefore,teaching and research section did an exploratory reform on experiment diagnosis teaching by clearly defining teaching contents,emphasizing clinical thinking way,reforming experimental teaching,adding multimedia to assist teaching and cultivating high quality teaching teams.As a result,the reform enhanced study interest of students,promoted teaching quality and effects greatly and achieved preliminary success.
ABSTRACT
<p><b>OBJECTIVE</b>Luteolin, a flavone, has considerable neuroprotective effects by its anti-oxidative mechanism. However, it is still unclear whether luteolin can protect neurons against oxygen-glucose deprivation/reperfusion (OGD/R) induced injury.</p><p><b>METHOD</b>After 2 hours oxygen-glucose deprivation and 24 hours reperfusion treatment in primary cultured hippocampal neurons, the neuron viability, survival rate and apoptosis rate were evaluated by MTT assay, lactate dehydrogenase (LDH) leakage assay and Hoechst staining, respectively. The activity of Na+/K+ -ATPase was examined in cultured neurons or in the hippocampus of SD rats treated by 10 minutes global cerebral ischemia and followed 24 hours reperfusion.</p><p><b>RESULT</b>Treatment by OGD/R markedly reduced neuronal viability, increased LDH leakage rate and increased apoptosis rate. Application of luteolin (10-100 micromol x L(-1)) during OGD inhibited OGD/R induced neuron injury and apoptosis in a dose-dependent manner. Compared to the control group or OGP/R-treated neurons, the activity of Na+/K+ -ATPase was significantly suppressed in global ischemia/reperfusion group or OGD/R-treated neurons. Application of luteolin during ischemia or OGD preserved the Na+/K+ -ATPase activity. Furthermore, inhibition of Na+/K+ -ATPase with ouabain attenuated the protective effect afforded by luteolin.</p><p><b>CONCLUSION</b>The data provide the evidence that luteolin has neuroprotective effect against OGD/R induced injury and the protective effect may be associated with its ability to improve Na+/K+ -ATPase activity after OGD/R.</p>
