Purpose:Our experiments are dealing with the affect of docosahexaenic acid(DHA) in doxorubicin to cytoxicity effect of MDA-MB-435s, which is of the anti-human breast cancer and whether it is one of the effect mechanisms that it via the lipid peroxidation of DHA.Methods:Add different match such as anti-cancer drugs?PUFAs?oxidan system of sodium ascorbate and ?-methy-1.4-naphoqui-none?antioxidant of Dl-?-tocopherol and so on to the culture cell line of MDA-MB-435s each 24 hours for 6 days, estimate MDA by TBA with cell extracts and estimate the contents of NO via nitrite salt spectrophotography, then draw out a dosage-effect correlation straight line among contents of MDA,NO and cytoxicity. Mitox is used as contraposition to the peroxidation of ADM which is enhanced by DHA for peroxidation of mitox is low.Results:There have been obvious changes on the contents of MDA of the lipid peroxidation has paralled increased while NO has decreased. There is recitilinear correlation relationship among the contents of MDA and NO from cell extracts and the cytoxicity.Conclusions:It is obvious that DHA can add the cytoxicity of cell line of MDA-MB-435s with ADM, particularly after add non-cytoxicity oxidant. It is lipid peroxidation of oncocyte that one of the mechanisms of DHA can enhance anti-breast cancer effect of ADM.

Objective To observe the influence of Edaravone on the level of serum gastrin and efficacy in patients with craniocerebral injury.Methods 60 patients with craniocerebral injury were randomly divided into Edaravone group(30 cases) and Dexamethasone group(30 cases).Then each group received corresponding treatment.The level of serum gastrin was detected at 1st d,3rd d,5th d and 7th d after treatment.The curative effect was evaluated based on the neuroligical deficit score(NDS) and Barthel index(BI) one month after treatment.Results The level of serum gastrin in Edaravone group began to decrease at the 3rd d after treatment,at the 5th d and 7th d became to normal value.While,in Dexamethasone group 5th d after treatment,the level of serum gastrin began to decrease,but at the 7th d was still significantly higher than the normal value.The levels of serum gastim at 3 d,5 d and 7 d after treatment were significant difference between the two groups(P

The influence of MRI on severity grading and activity staging in thyroid associated ophthalmopathy (TAO) was evaluated.The results showed that MRI had a higher detection rate in abnormal extraocular muscle than NOSPECS scores(χ~2 = 19.37,P = 0.000).MRI had higher sensitivity,specificity,and accuracy in detection of active TAO than clinical activity score (100% vs 95.7%,88.2% vs 35.3%,96.9% vs 79.7%,respectively).Therefore,MRI improves early detection of atypical grade 4 cases.Signal intensity elevation in adipose suppressed T2WI is helpful to define active stage.

Objective To investigate the efficacy of ambroxol combined with penehyclidine hydrochloride for prevention of pulmonary complications after surgery due to acute abdomen in pediatric patients with upper respiratory tract infection.Methods Fifty pediatric patients with acute abdomen complicated with respiratory infection,of ASA physical status Ⅰ or Ⅱ,aged 6 months-5 yr,were randomly divided into test group (group A) and control group (group B),with 25 cases in each group.Immediately after admission to the operating room,ambroxol 1 mg/kg and penehyclidine hydrochloride 0.02 mg/kg were injected intravenously in group A,and atropine 0.02 mg/kg was given in group B.Extubation time and development of laryngospasm,bronchospasm and hypoxemia were recorded.The patients were followed up for 72 h after surgery and the development of postoperative pulmonary complications was recorded.Results Compared with group B,the incidence of hypoxemia and pulmonary complications was significantly decreased,and extubation time was shortened in group A.Conclusion Ambroxol combined with penehyclidine hydrochloride can prevent pulmonary complications after surgery due to acute abdomen and is helpful for prognosis in pediatric patients with upper respiratory tract infection.

Objective To investigate the effect of liraglutide combined with glargine insulin in treating the patients with newly diagnosed type 2 diabetes mellitus (T2DM).Methods Sixty-one cases of newly diagnosed T2DM in the endocrinology department of Affiliated Chaozhou Central Hospital of Southern Medical University,from August 2014 to December 2015 were selected and divided into two groups according to the random number table.The observation group (29 cases) was treated with liraglutide combined with glargine insulin and the control group (32 cases) was given the intensive insulin therapy.The curative effects before and after treatment were analyzed and compared between the two groups.Results The fast plasma glucose(FPG),postprandial 2 h blood glucose(PPG),glycosylated hemoglobin(HbA1c),fasting C peptide(FCP),postprandial 2 h C peptide(PCP),insulin resistance index(HOMA-IR),blood lipid indicators and body mass index after 12-week treatment were decreased in the treatment and follow up periods,while pancreatic β cell function index (HOMA-β) and HDL-C were increased,indicating that the two kinds of treatment method all were effective.The effect onset in the observation group was faster,the above indexes after 4-week treatment were significantly improved compared with before treatment.The above indexes after 4-,12-week treatment in the observation group were significantly superior to those in the control group,the difference was statistically significant(P<0.05).Conclusion Liraglutide combined with glargine insulin has better effect in the aspects of reducing blood glucose,regulating blood lipid,decreasing the body mass and islet function recovery than the intensive insulin treatment and is worthy of clinical promotion and application.

Objective To observe the electrophysiological characteristics of the inward current of cardiomyocyte-like cells derived from rat bone marrow mesenchymal stem cells (MSCs). Methods Bone marrow specimens was extracted from SD rats aged 1 month. MSCs were isolated by gradient centrifugation and obtained by adherence culture. The second-passage MSCs were treated with 10 ?mol/L 5-azacytidine and incubated for 24 h. After 4 weeks, cardiomyocyte-like cells were identified by immunocytochemical staining technique, then used to detect the inward current with the whole-cell patch-clamp technique, which results were compared with the normal cardiomyocytes and the MSCs without induction. Results Some cardiomyocyte-like cells were stained positive for troponin T, and the quickly activated and inactivated inward currents were elicited 4 weeks after 5-aza cytidine treatment. The inward currents of cardiomyocyte-like cells recorded in the same square pulse were weaker than that of the normal cardiomyocytes, and the I-V curve of cardiomyocyte-like cells was right-shifted. Conclusion After treated with 5-azacytidine, MSCs differentiate into cardiomyocyte-like cells which express the excitable inward current.
