RESUMO
OBJECTIVE： To investigate the effect mechanism of diazoxide on the proliferation and apoptosis of chondrocytes with oxidative injury based on endoplasmic reticulum stress （ERS） pathway. METHODS： SD mice were selected for primary culture of articular chondrocytes. The 3rd generation chondrocytes were randomly divided into control group， injury model group and diazoxide group. Control group didn’t receive any treatment. The injury model group was incubated with 300 μmol/L hydrogen peroxide （H2O2） at 37 ℃ for 8 h. Diazoxide group was pretreated with 300 μmol/L diazoxide at 37 ℃ for 0.5 h，and then incubated with 300 μmol/L H2O2 for 8 h. The proliferation of chondrocytes was detected by CCK-8 assay. The apoptosis rate of chondrocytes was detected by flow cytometry. The expression of ERS-related proteins [Caspase-3， Bcl-2-associated X（Bax），C/EBP homologous protein （CHOP）] were detected by Western blotting assay. RESULTS： Compared with control group， the proliferation activity of chondrocytes in injury model group was significantly decreased， while apoptosis rate was increased significantly（P＜0.05）；the protein expression of Caspase-3， Bax and CHOP were increased significantly （P＜0.05）. Compared with injury model group， the proliferation activity of chondrocytes in diazoxide group was increased significantly， while the apoptosis rate was decreased significantly （P＜0.05）； the expression of above related proteins were decreased significantly （P＜0.05）. CONCLUSIONS： Diazoxide can improve the proliferation activity of chondrocytes with oxidative injury and inhibit their apoptosis by inhibiting ERS pathway.
RESUMO
OBJECTIVE： To observe the efficacy and safety of fluorouracil combined with paracetamol in the treatment of knee osteoarthritis and its effects on related indexes. METHODS： Totally 115 patients with knee osteoarthritis admitted to our hospital from March 2015 to March 2018 were divided into control group （57 cases） and observation group （58 cases） according to medication plan. Control group was given Paracetamol tablets 0.3 g orally， 3 times a day， for consecutive 8 weeks. Observation group was additionally given intra-articular injection of Fluorouracil injection 0.075 g on the basis of control group， once a week， 4 times as a treatment course， for 2 courses in total. Clinical efficacies， VAS scores， Lysholm knee scores， Fugl-Meyer Assessment （FMA） scores， Barthel indexes， WHO QOL-BREF scores before and after treatment and the occurrence of ADR of 2 groups were observed. RESULTS： The total response rate of observation group was 94.83％， which was significantly higher than 78.95％ of control group （P＜0.05）. Before treatment， there was no statistical significance in VAS score， Lysholm knee scores， FMA scores， Barthel index or QOL-BREF scores between 2 groups （P＞0.05）. After treatment， VAS scores of 2 groups were significantly lower than before treatment， and the observation group was lower than the control group； Lysholm knee scores， FMA scores， Barthel indexes and QOL-BREF scores were significantly higher than the same group before treatment， and observation group was significantly higher than control group （P＜0.05）. There was no statistical significance in the incidence of ADR between 2 groups （P＞0.05）. No severe ADR was found in 2 groups during treatment. CONCLUSIONS： Fluorouracil combined with paracetamol can significantly improve therapeutic efficacy of patients with knee osteoarthritis， and can significantly improve knee function， motor function， self-care ability and quality of life without increasing the occurrence of ADR.
RESUMO
Objective: To evaluate the clinical value of clinical pharmacists in clinical treatment team through participating in the treatment of one case of MRSA infection.Methods: According to the infection site, MRSA infection treatment principle and the characteristics of drug treatment, clinical pharmacists assisted physicians in optimizing the therapy plan and provided the pharmaceutical care.Results: Physicians adopted the clinical pharmacist's suggestions, and the symptoms of patient were improved with effectively reduced ADR.Conclusion: The participation of clinical pharmacists in the optimization of anti-infective therapy plan can improve efficacy and security.
RESUMO
OBJECTIVE:To investigate the effectiveness and safety of 2 kinds of proton pump inhibitors in the treatment of coronary heart disease (CHD).METHODS:In retrospective study,a total of 92 patients with CHD were selected from our hospital during Jun.2015-May 2016,and then divided into rabeprazole group (30 cases),esomeprazole group (32 cases) and control group (30 cases) according to therapy plan.Control group received basic therapy plan.Rabeprazole group and esomeprazole group were additionally given sodium rabeprazole enteric-coated tablets and Esomeprazole magnesium enteric-coated tablets 20 mg,po,bid,on the basis of control group.A treatment course lasted for 30 d,and both medication groups received 2 courses of treatment.Blood uric acid levels,urine pH values,blood ion levels (Na+,K+,Ca2+,Cl-) were detected before and after treatment.The occurrence of cardiovascular adverse events,coronary adverse events and other adverse events were observed in 2 groups during treatment.RESULTS:Before treatment,there was no statistical significance in above indexes among 3 groups (P＞0.05).After treatment,the levels of blood uric acid,K+ (except for control group),Ca2+ and Cl-were decreased significantly,while urine pH values and blood Na+ levels were increased significantly;the levels of blood uric acid and Ca2+ in rabeprazole group and esomeprazole group were significantly lower than control group,while urine pH value and blood Na+ level were significantly higher than control group,with statistical significance (P＜0.05).After treatment,the level of blood uric acid in rabeprazole group was significantly lower than esomeprazole group,with statistical significance (P＜0.05).But there was no statistical significance in urine pH values or ion levels between 2 groups (P＞0.05).Compared with control group,the incidence of acute thrombosis in rabeprazole group and esomeprazole group were decreased significantly,and the incidence of joint swelling and pain were increased significantly,with statistical significance (P＜0.05).There was no statistical significance in the incidence of coronary adverse events among 3 groups (P＞0.05).CONCLUSIONS:Rabeprazole and esomeprazole can significantly reduce the level of blood uric acid and the incidence of acute thrombosis,increase urine pH value and blood Na+ levels,decrease blood Ca2+ level and increase the risk of fracture or hypocalcemia in patients with CHD.Therefore,the dosage regimen should be adjusted according to the specific situation of patients in clinical practice
RESUMO
Objective To observe the clinical efficacy of auricular point sticking plus basic nursing for constipation of excessive syndrome in acute stage of stroke.Method Ninety patients with constipation of excessive syndrome in acute stage of stroke were randomized into a treatment group and a control group, 45 cases in each group. The treatment group was intervened by auricular point sticking plus basic nursing, while the control group was by basic nursing alone. The major symptom scores were observed before intervention and after 2-treatment courses, and the clinical efficacies were compared between the two groups.Result Respectively after 1 and 2 treatment courses, there were significant differences in comparing the major symptom scores between the two groups (P<0.05). The total effective rates were respectively 60.0% and 67.5% in the treatment group respectively after 1 and 2 treatment courses, versus 37.5% and 45.0% in the control group, and the differences were statistically significant (P<0.05). Conclusion Auricular point sticking is an effective approach in treating constipation of excessive syndrome in acute stage of stroke.
