ObjectiveTo explore the efficacy of calcitonin combined with glucosamine hydrochloride on knee osteoarthritis.
MethodsAccording to Kellgren-Lawrence radiographic scoring system, 156 patients with knee osteoarthritis diagnosed from November 2014 to April 2015 were classified as mild, moderate and severe cases. All of the patients were divided into control group (treated by glucosamine hydrochloride only) and trial group (treated by calcitonin combined with glucosamine hydrochloride) via table of random sampling numbers (with 78 patients in each group). The West Ontario and Manchester University (WOMAC) score was recorded at the 6th week and the 3rd month after the medication treatment.
ResultsIn the patients with mild osteoarthritis, there were significant differences in WOMAC score of both groups at the 6th week and the 3rd month after treatment compared with those before the treatment (P<0.05); there were no significant differences between the two groups at the same time points after the treatment (P>0.05). In the patients with moderate osteoarthritis, WOMAC scores in the control group at the 3rd month differed much from that before the treatment (P<0.05); there were no significant differences between the two groups at the same time points after the treatment (P>0.05). In the patients with serious osteoarthritis, there was no significant difference in WOMAC scores in the control group after the treatment compared with that before the treatment (P>0.05); while in the trial group, the scores at the 3rd month after the treatment differed much from that before the treatment (P<0.05), and also from that in the control group (P<0.05).
ConclusionFor mild knee osteoarthritis, the combined treatment is not superior to the single use of glucosamine hydrochloride. For moderate knee osteoarthritis, the combined treatment has faster effect than the single use of glucosamine hydrochloride. For severe osteoarthritis, the use of single glucosamine hydrochloride is not effective, while the combination of calcitonin and glucosamine hydrochloride is effective at the 3rd month after the treatment.
ObjectiveTo explore the therapeutic effect of glucosamine hydrochloride combined with calcium and vitamin D on knee osteoarthritis.
MethodsA total of 120 female outpatients with knee osteoarthritis from January 2014 to January 2015 were selected. The patients were randomly divided into study group and control group (60 patients in each group) according to their treatment sequence. The patients in the study group were given oral calcium citrate, alfacalcidol and glucosamine hydrochloride while those in the control group were given glucosamine hydrochloride only. Both groups were investigated and scored by Western Ontario and McMaster University Osteoarthritis Index (WOMAC) questionnaire before and three and six months after treatment.
ResultsThree and six months after the treatment, WOMAC scores of both groups were lower than those before the treatment with significant differences (P<0.05). Three months after the treatment, WOMAC scores between the two groups didn't differ much (P>0.05), while the difference between the two groups was significant 6 months after the treatment (P<0.05). Three months after the treatment, the difference of total effective rate in the study group (43.3%) and control group (41.7%) was not significant (P>0.05), while the rate in the study group (65.0%) was obviously higher than that in the control group (46.7%) 6 months after the treatment (P<0.05).
ConclusionGlucosamine hydrochloride has exact effect on knee osteoarthritis. There are differences in the therapeutic effect on knee osteoarthritis between glucosamine hydrochloride combined with calcium and vitamin D and glucosamine hydrochloride alone after six-month treatment.
目的 了解社區人群對腦卒中危險因素及癥狀的知曉現狀。 方法 隨機抽樣調查1 208名居民及112名醫務人員的人口學特征、對危險因素及預警信號的知曉現狀及其影響因素、信息來源及需求情況。 結果 90.1%、100.0%的居民及醫務人員可辨識高血壓是卒中的危險因素，而社區居民及醫務人員對年齡、糖尿病、吸煙等危險因素的認識比例分別為65.0% 和85.0%，且對危險因素的控制策略缺乏了解。87.4%、100.0%社區居民及醫務人員將一側肢體的活動障礙作為卒中的第一大預警信號，其次為頭暈、步態不穩、頭痛、言語困難、視物模糊。卒中知識得分的單因素及多因素分析示：大學文化、已婚且在職的居民及高學歷的醫務人員對卒中信息的了解程度高。卒中信息的獲取途徑依次為電視、社區醫生/講堂、報紙、雜志、網絡。 結論 西部城市社區人群卒中知識知曉率低，開展針對低學歷醫務者的卒中培訓及低學歷、獨居及退休人員的居民講堂是改善現狀的必要途徑。同時也為政府建立有效的院前早期識別及快速轉診技術提供了依據。Objective To assess the baseline knowledge of risk factors and warning signs of cerebral apoplexy in communities. Methods A total of 1 208 inhabitants and 112 medical personnel were selected by systematic sampling. The questionnaire included social-demographic data, knowledge of cerebral apoplexy risk and warning signs and influencing factors, the sources and requirement of information about cerebral apoplexy. Results Hypertension was a risk factor in 90.1% of residents and 100.0% of medical personnel. Age, diabetes and smoking were identified as the risk factor in 65.0% of medical personnel and 85.0% of residents. Medical therapy of risk factors was insufficient. The most common warning signs of cerebral apoplexy was hemiplegia, the following were vertigo, ataxia, headache, aphasia and double vision. Stepwise multiple regression analyses showed that residents who had higher educational background, spousal, workers and community worker with higher educational background had higher knowledge scores of cerebral apoplexy. The main sources of information about cerebral apoplexy were television, doctors, newspaper, magazine and network. Conclusions At present, the urban community residents in west China are lacking in knowledge about cerebral apoplexy. Going forward, targeted educational residents and medical workers should be directed at those who was highly educated, living alone, and retired. It is also provide a theoretical basis for establishing a prehospital identification and transfer treatment system based on community in developing countries.
ObjectiveTo investigate the effect of icaritin on the small cell lung cancer cell lines NCI-H446 and its mechanism.
MethodsThe NCI-H446 cells at logarithmic growth phase were divided into control and icaritin groups. The cells in the control group were normally treated and cells in the icaritin group were incubated with icaritin (8 μmol/L). Thiazole blue and flow cytometry were used to examine the proliferation and apoptotic changes in the two groups 48 hours after incubation respectively. Gene expression of Janus kinase 2 (JAK2) and signal transducers and activators of transcription 3 (STAT3) were detected by real-time quantitative polymerase chain reaction. The changes of JAK2, STAT3, phospho-JAK2 (p-JAK2), phospho-STAT3 (p-STAT3), Bax and BCL-2 protein were detected by Western blotting.
ResultsCompared with the control group, the proliferation rate of NCI-H446 cells in the icaritin group was significantly lower (P<0.05), but the apoptotic rate of NCI-H446 cells in the icaritin group was significantly higher (P<0.05). After the treatment with icaritin, the expression of JAK2 and STAT3 mRNA had no obvious differences. The Western blotting results showed that there was no significant changes in total JAK2, STAT3 protein (P>0.05), but an increasing trend in p-JAK2, p-STAT3 and Bax was observed with the decreasing of BCL-2 (P<0.05).
ConclusionIcaritin can inhibit the proliferation and promote the apoptosis of NCI-H446 cells and the effect may be achieved through JAK2/STAT3 signal transduction pathway.
