Mitochondria play an important role in energy ( ATP ) production through oxidative phosphorylation pathway and the regulation of cell death by apoptosis. Mitochondrial dysfunction has been implicated in the pathophysiology of a number of neurodegenerative diseases. Glaucoma as a neurodegenerative disorder, mitochondrial oxidative stress in the pathogenesis of glaucoma and the damage of RGCs has received close attention in recent years. ln this article, we reviewed the current evidences and recent advances in the relationship between mitochondrial oxidative stress and the RGCs apoptosis.

Objective To study the influence of different dosages of atorvastatin in acute coronary syndrome female patients on vascular endothelial growth factor(VEGF) and brain natriuretic peptide(BNP).Methods 60 female cases of ACS patients were divided into A and B group.30 patients in the A group were given atorvastatin 20mg per night,while the other 30 patients in the B group were taken 40mg per night.The patients were followed four weeks by evaluating serum VEGF and BNP concentration.Results After treatment for four weeks,the patients in the two groups showed significant reduction in VEGF and BNP,however,the therapeutic group showed significant difference between the two groups.Additionally,the B group further showed significant reduction in VEGF and BNP.Conclusion Using high-dose atorvastatin lowers VEGF and BNP significantly,which could reduce female cardiovascμlar events.

Objective To conduct the clinical and pathological evaluation on the conservative surgery in tubal pregnancy . Methods 513 cases of tubal pregnancy in this hospital from January 2006 to December 2012 were divide into the conservative sur-gery group(A ,314 cases) ,samlpintectomy group(B ,43 cases) and the medication conservative treatment group (C ,156 cases) .The hospitalization days ,HCG negative-conversion time ,cure rate ,re-pregnancy outcome ,pregnancy during 1-year follow-up were com-pared between the group A and C .In group B ,43 cases of tubal pregnancy and accomplishing fertility were firstly performed the tubal linear incision in the pregnant site ,then the biopsy was conducted after stopping bleeding and finally the salpingectomy in af-fected side was performed .The tubal electric injury degree by the unipolar or bipolar electrocoagulation and the pathological changes under light microscope were observed .Results The hospitalization days ,symptom relief rate ,HCG negative-conversion time ,cure rate and re-pregnancy outcome had statistical differences between the group A and C (P<0 .05) .Conclusion The tubal conserva-tive surgery has short hospitalization time ,high symptom relief rate ,high cure rate and few complications .The pathological observa-tion shows the localized electrocoagulation injury .The pregnancy rate after surgery is high .

Mitochondrial oxidative stress has been recognized as a preliminary and critical factor that aggravates the pathological cascade of Alzheimer's disease, which induces the production of β-amyloid protein, upregulates the expression of phosphorylated tau protein and triggers oxidative damage to lipids, proteins and mitochondrial deoxyribonucleic acid. Central neurons are more vulnerable to oxidative stress than non-neuronal cells due to their high oxygen demand, abundant unsaturated fatty acids and antioxidant enzymes deficiency. On this account, this review introduces the causes of mitochondrial oxidative stress, and analyzes the important role of mitochondrial oxidative stress in the pathogenesis of Alzheimer's disease. Meanwhile, the review focuses on the design and intervention strategies of drug delivery systems targeting mitochondrial oxidative stress in neurons, aiming to provide new ideas for the prevention and treatment of Alzheimer's disease.

Objective To analyze the etiology and clinical feature of pi t uitary apoplexy.Methods The clinical data from 18 cases of pitui tary apoplexy were analyzed retrospectively.Results Main symptom s were headache in 12 cases and decreased visual acuity in 12 cases.Positive si ghs were temporal hemianopisia in 6 cases,unequal pupil in 3 cases,oculomotor ne rve(Ⅲ) paralysis in 2 cases and abducent nerve (Ⅵ) paralysis in 2 cases.Imagin g examinations showed CT positive finding in 4 cases and MRI positive finding in 6 cases.Tumor diameter was longer than 2 cm in 13 cases and less than 2 cm in 5 cases.Chromophobe pituitary tumor was found in 11 cases.All cases received surg ical operation.Conclusion Clinical features of pituitary tumor a poplexy are atypical,of which headache and visual acuity decrease are the main s ymptoms.Most cases occur suddenly or primary symptoms are deteriorated suddenly. CT and MRI positive findings are helpful for diagnosis.

Objective To understand the actual psychological conditions of pregnant patients with gynecologic malignancies during chemotherapy so as to instruct the nurses to provide individualized psychological care to the patients and their relatives. Method The in-depth interviews were conducted to 7 patients by implementing the phenomenological approach of qualitative study. The acquired data were analyzed. Result The patients experienced four psychological conditions: pessimism about prognosis, anxiety to know more about the chemotherapy and guilty to their family and hope for treatment effect. Conclusion Nurses should pay attention to the psychological conditions of pregnant patients with gynecologic malignancies and help them successfully live through the treatment.

Objective To observe the clinical effects of the homemade medicated and dietary compound granules in treating sub-health insomnia with deficient cultivation of heart-spirit. Methods Sixty qualified patients were randomly divided into treatment group and control group, 30 cases in each group. The treatment group was given homemade medicated and dietary compound granules(mainly composed of Semen Ziziphi Spinosae, Radix Codonopsis, Sclerotiium Poriae Circum Radicem Pini, Radix Polygalae, Flos Rosae Rugosae, Plumula Nelumbinis, Fructus Ziziphi Jugubae, and Arillus Longan). The control group was given Oryzanol powder. The course of treatment lasted for half a month. Before and after treatment, the scores of Pittsburgh Sleep Quality Index(PSQI) and the traditional Chinese medicine(TCM)symptom rating scale were observed, and the clinical efficacy of the two groups were also evaluated. Results After treatment for half a month and after suspension of medicine for half a month , (1) the total effective rate of the treatment group was higher than that of the control group (P<0.05);(2) the total PSQI scores , sleep quality scores , falling asleep time scores , and daytime function disorder scores were decreased in the treatment group (P < 0.01 compared with those before treatment) , but the scores of each PSQI item in the control group stayed unchanged (P > 0.05). The total PSQI scores , sleep quality scores , falling asleep time scores, and daytime function disorder scores of the treatment group were lower than those of the control group (P<0.01);(3) the total scores of TCM symptoms as well as the scores of dreaminess and susceptibility to awakening, palpitation and amnesia, lassitude and weakness, poor appetite, pale complexion, vertigo and dizziness, abdominal distension and loose stools were declined in the treatment group (P < 0.05 or P < 0.01 compared with those before treatment). Conclusion Medicated and dietary compound granules are effective on improving sleep quality, shortening time to fall asleep, improving sleep disorder, increasing the efficiency of daytime function, improving patients’ mental state entirely, and maintaining the short-term curative effect.
