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 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.

This study aims to establish a method to determine the serum acetaminophen concentration based on diazo reaction, and apply it in the gastric emptying evaluation. Theoretically, acetaminophen could take hydrolysis reaction in hydrochloric acid solution to produce p-aminophenol, which could then take diazo reaction resulting in a product with special absorption peak at 312 nm. Then the serum acetaminophen concentration and recovery rate were calculated according to the standard curve drawn with absorbance at 312 nm. ICR mice were given a dose of acetaminophen (500 mg x kg(-1)) by gavage and the serum acetaminophen was dynamically measured through the diazo reaction. Besides, ICR mice were subcutaneously injected with the long-acting GLP-1 analog GW002 before the gavage of acetaminophen, and serum acetaminophen concentration was measured as above to study how GW002 could influence the gastric emptying. The data showed acetaminophen ranging from 0 to 160 μg x mL(-1) could take diazo reaction with excellent linear relationship, and the regression equation was y = 0.0181 x +0.0104, R2 = 0.9997. The serum acetaminophen was also measured with good linear relationship (y = 0.0045 x + 0.0462, R = 0.9982) and the recovery rate was 97.4%-116.7%. The serum concentration of acetaminophen reached peak at about 0.5 h after gavage, and then gradually decreased. GW002 could significantly lower the serum acetaminophen concentration and make the area under the concentration-time curve (AUC) decrease by 28.4%. In conclusion, a method for the determination of serum acetaminophen based on the diazo reaction was established with good accuracy and could be used in the evaluation of gastric emptying.

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.

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.
