Objective To summarize the treatment experience of acute cerebral infarction (ACI)combined with deep venous thrombosis (DVT) of lower extremities in the elderly. Methods Thirty cases of elder patients with ACI combined with DVT (ACI group) were enrolled in this study, and 31 cases of elder patients with DVT were served as control group. All the patients were immobilized for 3 days and treated with low molecular heparin calcium (100 IU/kg,Q12 hX14 d). On the tenth day,warfarin was used and INR was controlled in 2.0～2.5. Low molecular dextran was infused intravenously per day for 14 days (500mg/d). Results Edema in the lower limbs of patients were apparently reduced. 4 eases had cerebral hemorrhage in ACI group, and none in the control group.Hemorrhage occured from 3 to 7 days during the treatment with low molecular heparin calcium. One of the patient died of massive intraeranial hemorrhage with lung infection. Conclnsions It should be more careful to use the low molecular heparin to treat the elder patients older than 80 years old with ACI combined with DVT.

Objective: To observe the balance of modified coagulation and fibrinolysis in patients undergoing open heart surgery with cardiopulmonary bypass (CBP). Method: The balance of modified coagulation-fibrinolysis in 20 cases were measured by coagulation-fibrinolysis dynamicography instrument (FD-Ⅲ) at the pre-CPB, post-CPB, 24, 48 and 168 hours postoperatively. Result: At the post-CPB, coagulation starting time(CST), maximum coagulation time (MCT), whole time of fibrinolysis reaction (WFT) and balance time (BLT) were significantly more than at pre-CPB (P

Objective:To investigate the clinical therapeutic effect of low-dose chemotherapy in advanced gastrointestinal cancer patients with weak physical condition, and to evaluate the related factors affecting the prognosis.Methods:The clinical data of 118 advanced gastrointestinal cancer patients with weak physical condition who were admitted to Xiamen Branch, Zhongshan Hospital, Fudan University from March 2018 to May 2019 were retrospectively analyzed. Kaplan-Meier method was used to make survival analysis in patients stratified by different factors, and log-rank was used to test. Multiple factor analysis of prognosis was performed by using Cox regression model. The association of clinicopathological factors with the prognosis was evaluated.Results:Among 118 patients, 16 (13.6%) cases were esophageal cancer, 41 (34.7%) cases were gastric cancer, 48 (40.7%) cases were colorectal cancer, 13 (11.0%) cases were pancreatic cancer. The overall survival (OS) rates of 6 months and 1-year were 44.1% and 10.2%, respectively. Survival analysis showed that patients with hemoglobin ≥100 g/L, serum albumin > 40 g/L and normal gastrointestinal function had better OS (all P < 0.05), while patients with physical status score of 3 scores and pain had worse OS (all P < 0.05). Cox multivariate analysis showed that after adjusting age and gender, hemoglobin level ( HR = 0.314, 95% CI 0.241-0.977, P = 0.001), pain ( HR = 2.016, 95% CI 1.697-7.038, P = 0.008) and gastrointestinal function ( HR = 1.751, 95% CI 1.607-6.080, P = 0.036) were independent influencing factors of OS in advanced gastrointestinal cancer patients with weak physical condition after receiving low-dose chemotherapy. Conclusions:Low-dose chemotherapy can still benefit advanced gastrointestinal cancer patients with weak physical condition. Hemoglobin level, pain and gastrointestinal function are independent prognostic factors for these patients.

AIM: To determine whether Jiunaoning injection has protective effects on oxygen/glucose-deprived and reperfusion injury-induced neurons. METHODS: Various concentrations of Jiunaoning injection (0.5-5 mL/L) were used to observe their effects on cultured rat cortical neurons induced by oxygen/glucose-deprived and reperfusion injury in various time points. The neuronal metabolic rate and viability were assessed by using 3-(4,5-dimethylthiazol)-2, 5-diphenyl-tetra zoliumbromide (MTT) and lactate dehydrogenase (LDH) assay. RESULTS: Jiunaoning injection enhanced the neuronal metabolic rate in a dose-dependent manner in the range from 0.5 to 5 mL/L, and Jiunaoning injection (1.5-2.5 mL/L) enhanced the neuronal metabolic rate, decreased the cell death rate and depressed LDH leak rate significantly. CONCLUSION: Jiunaoning injection has an affirmative protective effect on oxygen/glucose-deprived and reperfusion-induced neuronal injury.

Objective To culture human embryonic germ cells in vitro and identify them by observing the expression of the surface markers SSEA-1 and Oct-4. Methods The gonadal ridges and mesenteries of human embryos at 5～9 weeks post-fertilization were isolated and then cultured in vitro.Flow cytometry and immunocytochemistry were applied to detect whether the cells cultured express SSEA-1 and Oct-4.Immunohistochemistry was also carried out to observe the expression of SSEA-1 on the PGCs which locate in the gonadal ridge. Results Both the cells and the cellular colonies cultured in vitro expressed SSEA-1 and Oct-4.The immunohistology study of gonadal ridges also showed that there were many PGCs which were SSEA-1 positive in it.Conclusion The cells we obtained through tissue culturing are undifferentiated human embryonic germ cells,which originate from hPGCs.

Objective To investigate the value of differential diagnosis for subcortical ischemic vascular dementia(SIVD)and Alzheimer's disease(AD)with memory and executive screening(MES) scale. Methods Fifty SIVD and 50 AD patients treated in the outpatient and wards of the Department of Neurology,Fuxing Hospital,Capital Medical University from June 2012 to November 2013 were enrolled retrospectively. They were enrolled in either a SIVD group or an AD group. Fifty healthy subjects in Yuetan community of Fuxing hospital were selected as a control group at the same period. The age,sex and education level of the subjects in the 3 groups were matched. The Mini-Mental State Examination( MMSE) and MES were used to measure all subjects and were compared;receiver operating characteristic curves was used to analyze the radio of memory and executive part for SIVD and AD discrimination. Results (1)There was no significant difference in total MMSE score between the SIVD group and the AD group(20. 6 ± 5. 5 vs. 20. 6 ± 3. 3;P>0. 05).(2)There were significant differences in each MES indexes among the patients of the 3 groups(all P>0. 05). The 1,3,4 and 5 scores for the sentence memory in the SIVD group were significantly higher than those of the AD group. There were significant differences(all P<0. 01). The indicators of executive part:the continuous action,instruction and action contradictory stimulation,knock and un-knock with finger scores of the SIVD group were all lower than those of the AD group(5. 1 ± 3. 1 vs. 7. 3 ± 2. 1, 5. 2 ± 3. 0 vs. 7. 7 ± 1. 9,3. 5 ± 4. 4 vs. 6. 2 ± 4. 3;all P<0. 01). The MES-R of the SIVD group was higher than that of the AD group(1. 2 ± 0. 7 vs. 0. 5 ± 0. 2;P>0. 05).(3)When MES-R was≥0. 7,the sensitivity and specificity of differentiating SIVD were 76. 7% and 83. 3%,and the total score of MMSE for differentiating the sensitivity and specificity of SIVD were 40. 0% and 0. 7%. Conclusion The differences of MES reflecting sentence memory and executive part may better distinguish the patients with SIVD and AD.

Objective To analyze the language function impairment differences between the two steps from the form to sound processing and from the sound to meaning processing for pseudo-words reading in Alzheimer' s disease (AD).Methods The pseudo-words reading test consists two parts:pseudo-true words and pseudopseudo words.Each part had 10 words.All of the 20 words were presented randomly.Correct reading presents the processing of from form to sound,and correct judging presents the processing of from sound to meaning.Each correct respond get 1 score,otherwise get 0.Each part had a total score of 20.Results The pseudo-words reading test was performed to 41 mild AD participants with Mini-mental State Examination (MMSE) average scores of (21.06 ±2.86),and 135 normal controls with MMSE average scores of (28.08± 1.52).The two groups were matched in age,gender and education.For all of the mild AD group and normal control group,there was no significant difference between reading score and judging score in either pseudo-true words or pseudo-pseudo words (P＞0.05).Comparing with mild AD group and normal control group,there was no significant difference in reading score in either pseudo-true words or pseudo-pseudo words (P＞0.05).For judging score,there was significant difference in pseudotrue words (P＜0.01) but not in pseudo-pseudo words (P＞0.05).Conclusion Understanding real syllable is impaired in patients with mild AD.

Objective To investigate the application effect of pelvic rocking with balloon bionic midwifery in head dystocia. Methods Prospective research method was selected, and 400 pregnant women with head dystocia were divided into 2 groups by random digits table method with 200 cases each. The observation group was given pelvic rocking with balloon bionic midwifery delivery, and the control group was given gauge and comfortable posture with manual rotation fetal head delivery. The labor stage and delivery outcome were observed in two groups.

40 cases(control group)with aggressive periodontitis (AgP)received scaling and root planning (SRP)and 38 cases(test group)received SRP followed by oral administration of amoxicillin plus metronidazole for 7 d.Gingival crevicular fluid samples were exam-ined for the levels of MMP-1,MMP-8 and tissue TIMP-1 by ELISA before therapy,3 and 6 months after therapy,TIMP-1 /MMP-1 and TIMP-1 /MMP-8 ratios were calculated.The levels of MMP-1 and MMP-8 were decreased in both groups (P <0.05)at 3 and 6 months after therapy.TIMP-1 /MMP-1 and TIMP-1 /MMP-8 ratios were increased in the 2 groups(P <0.05)after treatment,3 months after therapy the ratio in test group was higher than that in control group(P <0.05).

This study is to determine the preventive effect and mechanism of targeting IL-17A on pulmonary inflammation and fibrosis after acute lung injury. Mice were treated with anti-IL-17A antibody on the day 7 and sacrificed on the day 14 after bleomycin lung injury. The pulmonary inflammatory status and the deposition of collagen were measured by HE and Sirius stains staining. The contents of hydroxyproline and collagen were measured by using commercial kits. The survival rate of mice was calculated by Kaplan-Meier methods. The inflammatory cytokines in bronchoalveolar lavage fluid were measured by ELISA and the expressions of inflammation-related molecules were detected by Western blotting assay. Targeting of IL-17A could prevent the development of lung inflammation, decrease collagen deposition and the contents of hydroxyproline, and protect against the development of pulmonary fibrosis, which together led to an increase in the animal survival. Moreover, blocking IL-17A decreased the expression ofpro-fibrotic cytokines such as IL-17A, TGF-beta1 and IL-13; increased the expression of anti-fibrotic or anti-inflammatory factors such as IFN-gamma, COX-2, 5-LOX, 15-LOX. Indeed, IL-17A antagonism suppressed the activation of pro-inflammatory p65NF-kappaB but enhanced the activation of pro-resolving p50NF-kappaB. In conclusion, that blockade of IL-17A prevents the development of pulmonary fibrosis from acute lung injury, is because blocking IL-17A may prevent acute inflammation converting to chronic inflammation.
