Objective To copy the mouse aging model with D-galactose,and to investigate the role of Schisandra total lignin (SCL)in the mouse brain tissue aging and its mechanism.Methods 50 mice were radomly divided into control group,model group (100 mg·kg-1 ·d-1),low dose (35 mg·kg-1 ·d-1)of SCL group (SCL-L), middle dose (70 mg· kg-1 · d-1 )of SCL group (SCL-M)and high dose (140 mg· kg-1 · d-1 )of SCL group (SCL-H)(n=10).D-galactose (100 mg·kg-1 ·d-1 )was injected into the mice hypodermically for 10 weeks to induce aging models in all the groups except control group,and 35,70,and 140 mg· kg-1 · d-1 SCL were administered for 10 weeks in SCL groups.The learning and memory abilities were measured by the Water Maze test.The expression levels of Bax,Bcl-2,ubiquitin (Ub),microtubule-associated protein light chain 3 (LC3)in the brain tissue of the mice in various groups were observed by Western blotting method. The LC3 protein expressions in mouse brain cortex and hippocampus were observed by immunohistochemistry.Results In learning and memory test,compared with control group,the swimming time of the mice in model group was increased (P<0.05),and the number of errors was increased (P<0.05);compared with model group,the swimming time in SCL-L,SCL-M and SCL-H groups was decreased (P<0.05)and the number of errors was also decreased (P<0.05). Compared with control group,the expression level of Bax was increased (P<0.05),the expression level of Bcl-2 was decreased (P<0.05),the expression levels of Ub and LC3-Ⅱ/LC3-Ⅰ proteins were increased (P<0.05)in model group;compared with model group,the expression level of Bax was decreased (P<0.05),the expression level of Bcl-2 was incerased (P<0.05),and the expression levels of Ub and LC3-Ⅱ/LC3-Ⅰ proteins were decreased (P<0.05)in SCL-L,SCL-M and SCL-H groups.In control group,the neuronal morphology was normal,and none of brown granules were visible in the cytoplasm of mouse brain cortex and hippocampus and the expression of LC3 protein was negative.In model group,the neurons were degeneration,and the number of LC3 protein positive cells in the cerebral cortex and hippocamptal tissue was increased (P<0.05).In SCL-L,SCL-M and SCL-H groups,the number of degenerative neurons was decreased,and the number of LC3 protein positive cells was decreased (P<0.05).Conclusion SCL can inhibit the D-galactose-induced brain tissue aging in the mice, and the mechanism is related to regulating autophagy and inhibiting apoptosis.

Objective To explore the relationship between serum 25 (OH)D level and cognitive function in patients with Alzheimer's disease (AD).Methods Totally 113 AD impatients were enrolled in this study.Their serum 25 (OH) D2,25 (OH) D3,and total 25 (OH) D levels were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS).Patients were divided into Vitamin D severe deficiency group [25 (OH)D level≤25 nmol/L],deficiency group [25 (OH)D levels:25-50 nmol/L],insufficiency group [25 (OH) D level:50-75 nmol/L],and sufficiency group [25 (OH) D level ≥ 75 nmol/L] according to the criteria proposed by US Institute of Medicine.The cognitive function was assessed by MMSE score.The association between serum 25 (OH) D level and cognitive function was systematically analyzed.Results The serum levels of 25 (OH) D,25 (OH) D2,and 25 (OH) D3 were (27.08 ± 15.33) nmol/L,(1.23 ± 0.93) nmol/L and (24.50 ± 13.04) nmol/L in AD patients.The proportions of severe deficiency,deficiency,insufficiency,and sufficiency were 60.18％ (68/113),30.97％ (35/113),7.97％ (9/113),and 0.88％ (1/113),respectively,among these AD patients.A positive correlation was found between serum 25 (OH) D concentration and MMSE score in AD patients.Conclusions Impatients with AD often have severe vitamin D deficiency and need vitamin D supplementation.Serum 25 (OH) D concentration is associated with cognitive function,and therefore vitamin D supplementation may improve cognitive function.

Objective To explore the clinical characteristics,management and pregnancy outcome in patients with ovarian tumor and ovarian tumor like condition complicated with pregnancy.Methods The clinical data of 248 patients with ovarian tumor and ovarian tumor like condition eomplicated with pregnancy who treated,operated and pathology conducted from January 2003 to December 2009 was analyzed retrospectively.Results Among of 248 patients,8 patients were found by pelrioscopy,184 patients were found by sonography.The rate of ovarian tumor and ovarian tumor like condition during pregnancy was 0.49％ (248/50 652),about 52.82％(131/248)were diagnosed as benign tumor,most of them were ovarian mature teratoma(22.18％,55/248).About 45.56％(113/248)were diagnosed as ovarian tumor like condition,most of them were ovarian chocolatecyst(23.79％,59/248).Four patients(1.61％,4/248)were ovarian malignant tumor.Two hundred and sixteen received operation,term birth was in 164 patients,premature birth was in 19 patients,miscarriage was in 33 patients.Conclusions Pelvioscopy and sonogaraphy are principally important in the diagnosis and detection of ovarian tumor during pregnancy.Pregnancy complicated with ovarian tumor or ovarian tumor like condition should be treated by tumor resection.Suitable surgery intervention during second trimester is safe.

Objective To evaluate the clinical efficacy and safety of compound polymyxin B ointment combined with desonide cream for the treatment of subacute or chronic eczema. Methods A multicenter, randomized, double?blind, parallel?group, controlled clinical study was conducted. Totally, 144 patients with subacute eczema and 144 patients with chronic eczema were enrolled into this study, and both randomly and equally divided into the test group and control group. The test group and control group firstly topically applied compound polymyxin B ointment and its vehicle respectively, then both topically applied desonide cream 3 hours later. The drugs or vehicle were applied twice a day in all the patients. Patients′ symptoms and signs (including degree of itching, inflammation, erosion/exudation and infiltration/thickening, as well as area of target lesions) were evaluated, and the time to onset and duration of itching?alleviating effect were recorded. The clinical efficacy and safety of treatments were analyzed and compared between the test group and control group. Results The total symptom and sign scores significantly decreased to different extents on days 7 and 14 in the test group(subacute eczema patients:6.09 ± 2.78 and 3.68 ± 3.18 vs. 13.44 ± 1.66; chronic eczema patients: 6.56 ± 2.68 and 4.38 ± 3.27 vs. 12.96 ± 1.16)and control group(subacute eczema patients:8.26 ± 3.17 and 5.28 ± 4.05 vs. 13.60 ± 1.75;chronic eczema patients: 8.84 ± 2.90 and 6.25 ± 3.78 and vs. 12.64 ± 1.18)compared with those at baseline. Moreover, the total symptom and sign score of patients with subacute or chronic eczema was significantly lower in the test group than in the control group on days 7 and 14(all P<0.05). A significant increment was observed in the degree of decrease in scores for itch, infiltration/thickening in patients with subacute eczema in the test group compared with that in the control group(all P<0.01), as well as in scores for itch, infiltration/thickening and area of target lesions in patients with chronic eczema in the test group compared with those in the control group (all P < 0.05). In addition, patients with subacute eczema in the test group showed significantly shorter onset and longer duration of itching?alleviating effect than those in the control group(both P<0.05). The time to onset of itching?alleviating effect was also significantly shorter in patients with chronic eczema in the test group than in those in the control group(P<0.000 1), but there was no significant difference in the duration of it between the two groups of patients with chronic eczema. Clinicians and patients were both more satisfied with therapeutic effects in the test group than in the control group(all P<0.05). Conclusions Topical compound polymyxin B ointment can increase the efficacy of topical desonide cream for the treatment of subacute or chronic eczema, especially subacute eczema. Compound polymyxin B ointment also shows a favorable therapeutic effect on itching and infiltration/thickening in patients with eczema.

Objectives To investigate the effect of bilateral arcuate artery suture hemostasis of corpus uteri (haemostasia) for postpartum hemorrhage due to uterine inertia during caesarean section,and to explore the change of blood vessels and blood flow of the uterus after surgery.Methods From May 2009 to Dec.2011,the 212 patients in No.202 People's Liberation Army Hospital received bilateral arcuate artery suture hemostasis of corpus uteri for postpartum hemorrhage due to uterine inertia during caesarean section.Among them,127 patients who failed to respond to conservative management and received haemostasia were defined as the ‘ haemostasia' group.23 patients who received the suture after they failed to respond to conservative management and other conventional surgical hemostasis were defined as the ‘ other +haemostasia' group.62 patients who received the suture simultaneously with conservative management were defined as the ‘ drug + haemostasia' group.The suture was done by the following steps:(1) The uterus should be exteriorised,and the fundus of uterus should be towards the head.(2)Transfix the anterior and posterior wall of corpus uteri with big blunt round needle and absorbable suture.The entry point was 2 cm above the uterine incision and 2 cm to lateral border of corpus uteri.The suture spanned the fundus of uterus,and was stretched tightly in front of the fundus,then tied knots were made.Bleeding volume,prompt hemostatic rate,effect rate,total effect rate and operation time were recorded.The resistance index (RI) of uterine artery,systolic/ diastolic blood pressure (S/D),the visualization ratio of uterine artery and the mean value of artery diameter were obtained through color Doppler ultrasonography and enhancement CT 6-12 months after the surgery.Results (1) In the ‘ drug + haemostasia' group,the bleeding volume was (532 ±28) ml.The operation time was (34 ± 3) min,and the prompt hemostatic rate was 97％.While the ‘ haemostasia' group had more bleeding volume,longer operation time and lower prompt hemostatic rate than the ‘ drug + haemostasia' group,with no statistically significant difference (P ＞ 0.05).In ‘ other + haemostasia' group,the bleeding volume was (1379 ± 95) ml.The operation time was (79 ± 15) min,and the prompt hemostatic rate was 78％.The differences were significant when compared to the other groups (P ＜ 0.01).There was no statistically significant difference on total effect rate among the three groups (P ＞ 0.05).(2) There was no statistically significant difference on the RI and S/D of bilateral uterine artery among all the groups 6-12 months after the surgery.(3)The visualization ratio of left uterine artery of the ‘ other + haemostasia' group was lower (87％) than the ‘ haemostasia' group (97％) and the ‘ drug +haemostasia' group (95％,P ＜ 0.05).There was no statistically significant difference between the ‘ haemostasia' group and the ‘ drug + haemostasia' group on the visualization ratio of bilateral uterine artery and the mean value of bilateral uterine artery diameter (P ＞ 0.05).Conclusions The bilateral arcuate artery suture hemostasis of corpus uteri is a simple,rapid,effective and safe method to control postpartum hemorrhage due to uterine inertia during caesarean section.The ovary and uterine blood flow are not affected after the surgery.

Objective To evaluate the therapeutic effects and complications of modified facial mask for non-invasive ventilation (NIV) in elderly patients with respiratory failure.Methods A total of 132 elderly patients(107 males and 25 female,aged 78.5±8.6 years) treated with NIV from February 2008 to May 2011 were randomized into two groups:modified facial mask(group A,n=68,56 males and 12 females,aged 78.8±22.2 years) and control facial mask(group B,n=64,64 males and 13 females,aged 76.6±20.4 years).Duration of NIV,time in RICU(respiratory intensive care unit),length of hospital stay,risk for hospital acquired pneumonia (HAP),risk for invasive ventilation,cure rates,in-hospital mortality,NIV failure rate and cost were compared between the two groups.The complications of NIV,such as oropharyngeal dryness,skin damage of face and nose,abdominal bloating,gas leakage from mask were also compared between the two groups.Results Compared with group B,duration of NIV(12.2±2.3 d vs.18.4±3.6d),time in RICU(7.3±3.2d vs.14.6t5.4d),length of in hospital stay(16.6±4.2d vs.28.2±6.2)d,and cost(2.23±0.12 ten thousand yuan vs.4.23± 0.24 ten thousand yua) in group A were significantly decreased(t=9.72,14.91,13.08,10.81 respectively,all P＜0.05).The risk for invasive ventilation [2.9％ (2 cases) vs.43.8％(28 cases)],NIV failure rate [5.9％ (4 cases) vs.12.5％ (28 cases)] were also decreased in group A compared with group B(x2 =31.26,25.74,both P＜0.05).Compared with group B,The complications of NIV such as skin damage of face and nose[4.4％ (3 cases) vs.37.5％ (24 cases)],abdominal bloating [2.9％ (2 cases) vs.28.1％ (18 cases)],gas leakage from mask [8.8 ％ (6 cases)vs.50％(32 cases)] in group A were significantly decreased(x2 =31.26,25.74,all P＜0.05).Conclusions Modified facial mask for NIV is effective in the treatment of elderly patients with respiratory failure.The complications and in-hospital mortality are reduced with the application of modified facial mask for NIV and it is highly tolerated by patients.Modified facial mask for NIV is the first choice in the treatment in elderly patients with respiratory failure.
