OBJECTIVE： To investigate the possible role of the alteration of mitochondrial transmembrane potentials(Δ Ψ m) in arsenic trioxide(As2O3)-induced apoptosis of human gastric adenocarcinoma cells(SGC7901).METHODS： Cell apoptosis was assessed through morphology， cell viability， the percentage of sub-G1 cells and phosphatidylserine(PS) externalization.the Δ Ψ m was detected on flow cytometry through double staining of Rhodamine 123 (Rh123) and propidium iodide(PI).RESULTS： The As2O3-induced apoptosis was associated closely with the disruption of the Δ Ψ m.CONCLUSION： The disruption of the Δ Ψ m is one of the mechanisms of As2O3-induced apoptosis.

Plasma cell mastitis,also known as periductal mastitis or mammary duct ectasia,always occurs in young women.Because of It's Complicated and varied clinical manifestations,it is easily misdiagnosed as breast cancer.Early diagnosis and staging helps to avoid unnecessary surgery.At present,There is no unified understanding to this kind of disease.Modern medicine mainly treated it by surgery while Traditional Chinese medicine believes it shoull be treated internally and externally.Complete resection of the lesion and the cosmetic effect is the focus of current research.This article reviews the progress of research in plasma cell mastitis etiology,pathology,diagnosis and treatment.

Objective To investigate the imaging features in neonates with hypoglycemic brain injury by early and serial MRI.Methods Neonates who were admitted to neonatal department from May 2005 to Jul 2013 received MRI and diffusion-weighted imaging(DWI) scan within 7 days after hypoglycemia.Fortynine neonates were diagnosed with hypoglycemic brain injury.Thirty-four neonates received second MRI scan between 2 ～3 weeks after hypoglycemia.Seven neonates received third MRI scan.Results All the 49 neonates showed hyperintensity on DWI in the regions of occipital and parietal lobe for the first MRI scan(mainly involved 33 cases).Six cases combined frontal lobe and temporal lobe.Ten cases presented widespread cortex and white matter involvement.All the cases presented hypointensity on DWI for the affected area,T1 and T2 weighted image signal changes were not obvious.Some cases presented deep white matter and gray matter injury.Thirty-four cases received second MRI scan between 2 ～3 weeks after hypoglycemia,20 presented hypointensity on DWI,hypointensity on T1 weighted image and hyperintensity on T2 weighted image.Eleven cases with normal signals,and the other 3 were absorbing.Seven cases received third MRI scan,appeared encephalomalacia,myelin retardation,white matter volume decreased,hypoplasia of corpus callosum.The more severe the clinical symptoms was,the more severe the degree of brain injury showed.Conclusion Cerebral occipital and parietal regions are the most vulnerable in neonatal hypoglycemic brain injury.Early DWI for the imaging diagnosis of hypoglycemic brain injury should be taken within one week after hypoglycemia.Mild injury is recoverable,but severe would chang into necrosis and encephalomalacia.Some combined deep white and gray matter injury might related to hypoxia and ischemia.

Esophageal carcinoma represents high incidence and mortality rate in China.Irinotecan (CPT-11) has shown promising activity in a number of gastrointestinal cancers,including esophageal cancer.This article reviews recent clinical trials of irinotecan-based chemotherapy and radiochemotherapy in esophageal carcinoma.

Objective To study the clinic effect and safety of inhaled nitric oxide for the neonates with hypoxic respiratory failure. Methods A total of 21 neonates with hypoxic respiratory failure were trea-ted with nitric oxide inhalation after ineffective treatment of conventional mechanical ventilation. The values of mean airway pressure( MAP) ,oxygenation index( OI) ,mean blood pressure and saturation of blood oxy-gen percutem( TcSaO2 ) were detected before and after nitric oxide inhalation. Meanwhile,the values of coag-ulation function,nitrogen dioxide concentration and methaemoglobin were monitored. Results The lung oxy-genation of 21 cases were significantly improved in 48 hours after nitric oxide inhalation,OI declined from 26. 600 ±4. 169 to 7. 500 ±1. 716,MAP decreased from(15. 100 ±2. 132)cmH2O(1 cmH2O=0. 098 kPa) to (8. 000 ± 0. 816) cmH2O,which all had statistical differences(P <0. 01). The monitoring of coagulation function was in the normal range. The levels of methaemoglobin were less than 3% and nitrogen dioxide less than 1 × 10 -6 . In this study,18 neonates survived,2 neonates died and 1 neonate gave up treatment. Conclu-sion Inhaled nitric oxide early can improve oxygenation effectively for neonates with hypoxic respiratory failure without obvious side-effect. However,it is not yet clear for its long-term prognosis and whether there is influence development of the nervous system.

ObjectiveTo observe the clinical efficacies of electroacupuncture and Prucalopride succinate tablets in treating functional constipation.MethodForty patients were randomized into two groups, 20 cases in each group. The treatment group was intervened by electroacupuncture, and the control group was byoral administration of Prucalopride succinate tablets. The major symptoms scores, stool shape score, serum substance P (SP), and somotostatin (SS) were observed.ResultAfter treatment, there were no significant inter-group differences in comparing the changes of defecation frequency and difficulty scores (P>0.05), while there were significant inter-group differences in comparing the changes of incomplete bowel evacuation sensation, abdominal pain, and stool shape scores (P<0.05); the serum SP and SS levels were significantly changed after treatment in both groups (P<0.05); the total effective rate was 90.0% in the treatment group versus 85.0% in the control group, and the difference was statistically insignificant (P>0.05).ConclusionElectroacupuncture and Prucalopride succinate tablets can produce equivalent efficacies in treating functional constipation, and have their own advantages in improving the relevant symptoms. Therefore, treatment should be chosen according to the disease condition.

Objective] To observe the clinical effects of Tianwang Buxin decoction in the treatment of heart Yin deficiency type of Generalized Anxiety Disorder. [Methods] 63 patients with Generalized Anxiety Disorder(heart Yin deficiency type) were randomly divided into three groups: Tianwang Buxin decoction group, paroxetine group, Tianwang Buxin decoction combined paroxetine group, course of treatment for 8weeks.Contrast the scores of three groups by HAMA before and after treatment. [Results] The clinical efficacy was almost the same among the three groups without significant difference, but the decrease of HAMA scores of Tianwang Buxin decoction combined paroxetine group was obviously lower than Tianwang Buxin decoction group and paroxetine group(P<0.05), among which, TCM group and combination group of TCM and WM had less side effect than WM group. [Conclusion]The clinical efficacy of Tianwang Buxin decoction group is almost the same with the paroxetine group without significant difference. The clinical efficacy of Tianwang Buxin decoction combined paroxetine group is more significant.

Cultured porcine endothelial cells (EC) produce and secrete plasminogen activators (PA). If the serum free medium conditioned by vascular smooth muscle cells (SMC-CM) mixed with the medium conditioned by endothelial cells (EC-CM), the PA activities of the latter decreased significantly. Coeultivation of EC with SMC inhibited 70.7% PA activity of EC. Gel eletrophoretic analysis (SDS-PAGE) of SMC-CM followed by reverse fibrin autography demonstrated PA inhibitory activity in the molecular weight range of 49, 000-52, 000 similar to those identified by Laug (1985).In this study it was also investigated the effect of a Chinese herbal medicine-Radix Salviae Miltiorrhizae (RSM) on the inhibitory activity. SMC were incubated with RSM (0.1% in M-199, the final concentration was 1.5mg/ml) for 24hr. The SMC-CM collected before and after RSM treatment were mixed with EC-CM and urokinase respectively. The results show that the residual PA activities in EC-CM or urokinase samples mixed with SMC-CM treated with RSM were significantly higher than that mixed with SMC-CM without treatment with RSM. SMC-CM neutralized the PA activities in EC-CM or urokinase samples in a concentration dependent manner (P
