1.The influence of different dosages of atorvastatin in acute coronary syndrome female patients on vascular endothelial growth factor and brain natriuretic peptide
Chinese Journal of Primary Medicine and Pharmacy 2013;20(2):244-246
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.

Medical Journal of Chinese People's Liberation Army 2001;0(10):-
Objective To investigate the clinical effect of par ti al pulpotomy in the dreatment of complicated crown fracture of permanent inciso rs with pulp exposure. Methods 44 soldiers suffering from compl icated crown fracture of the incisors with exposure of pulp as a result of injur y 46 during training were enrolled for study. Altogetber teeth were treated with partial pulpotomy, and they were followed-up for 1 to 5 years. Result One of the teeth was found fo have pulp necrosis one year after treatm ent dut to falling off of the filling. The treatment failed in other toeth dut t o polpitis 2 to 4 years later. The treatment was successful in 42 teeth (91.3%) . Conclusion Partial pulpotomy was an effective treatment for c omplicated crown fracture of permanent incisors with exposureof pulp.
3.Oxidative stress - mitochondrial dysfunction and the relationship with retinal ganglion cell apoptosis
International Eye Science 2015;(2):238-241
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 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 .

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 investigate and compare the effects of pretreatment with different concentrations of trarnadol and morphine on the differentiation of hunan helper T cells (Th) in vitro. Methods Fifteen ASA Ⅰ patients of both sexes (8 males, 7 females) aged 23-59 yrs scheduled for minor day-care surgery were enrolled in this study. The patients had never taken morphine and tramadol before. Blood samples were taken from peripheral vein. Whole blood and mononuclear cells isolated from peripheral blood (PBMCs) were incubated with morphine 10, 100 or 1000 ng?ml-1(group M1 , M2 , M3) or tramadol 50, 500, 5000 ng?ml-1(group Q1, Q2, Q3) for 24 h. Then irrntants was added and incubated for another 5 or 24 h. In the whole blood the level of IL-2 and IFN-?(as markers of Th1 cells) and IL-4 and IL-10 (as markers of Th2 cells) were determined using three-color flow cytometry. In PBMCs the expression of CD4+ and CCR5+ (as markers of Thl cells) and CD4+ and CCR3+ (as markers of Th2 cells) were determined. The Th1/Th2 ratio was calculated. Results Pretreatment with morphine or tramadol significantly increased the number of Th2 cells while the number of Thl cells significantly decreased both in a dose-dependent manner leading to a significant decrease in Th1/Th2 ratio. Conclusion Tramadol and morphine can inhabit in vitro the cellular immune function in dose-dependent manner. The immunosuppressive effect of tramadol is less than that of morphine.

Objective To evaluate the safety and effectis of methylene blue photochemical inactivation of virus in red blood cell (RBC) by using animal models. Methods ①The effects of improving anemia was assessed by transfusing MB P RBC to Beagle’s dog. ②Duck hepatitis B virus(DHBV)was serially diluted and added into human RBC, and then one day old ducklings were inoculated with that treated RBC by intravenous injection. Sera from ducklings were collected and tested by dot hybridization. Infectivity of DHBV (ID 50 ) in RBC was calculated before and after the treatment. Results Dog RBC treated by MB P were not hemolysed after autologous transfusion. There were no changes in serum ALT, AST, BUN, and creatinine after transfusion. The ID 50 contained in RBC changed from 10 3.35 to 10 8.35 after treatment. Conclusion MB P viral inactivation of RBC is safe and effective.

Objective To investigate the caregivers' difficulty in taking care of the elderly and the related factors. Method A self-designed questionnaire was used to investigate the difficulties in care giving among 1,517 caregivers. Results The total score on the difficulties was (16.16 ±5.79). The preventive factors were good care-related knowledge and family income and the risk factors were advanced age, poor health condition of the patients ( all P<0.01). Conclusions The difficulty in caring the elderly are varied. We should attach importance to those caregivers of advanced age, with lower income and lack of care-related knowledge. Meanwhile, we should provide consultation, education and training for caregivers according to their different situation, and carry out targeted and multi-level support services so as to solve their problems in care to the patients.
