Objective To estimate the prevalence and related risk factors of post-stroke depression (PSD) in ischemic stroke survivors from community-based medical centers in urban areas of Beijing.Methods Five community-based medical centers in urban areas of Beijing were selected.Patients with first-ever or recurrent ischemic stroke were evaluated from January 2003 to December 2006. The prevalence of PSD was evaluated by Self-Rating Depression Scale (SDS), and the information on the onset of stroke, vascular risk factors and living style was also collected.Results Totally 1089 stroke patients were registered, 1074 cases among which had complete information and met inclusion criteria. The mean age of the patients was (65.0 ± 8.9) years with a median stroke course of 13.0 months. The overall prevalence of PSD was 49.9% (536/1074), and the proportions of mild, moderate and major PSD were 52.2%, 36.0% and 11.8%, respectively. There were no significant differences in prevalence of PSD among different stages of stroke and the prevalence of PSD was 51.3% within 6 months after stroke onset, 47. 1% during 6-18 months and 53.2% after 18months. Low education, activities of Daily Living (ADL) dependence, cognition impairment and recurrence of stroke were independent risk factors for PSD.Conclusions The prevalence of PSD among ischemic stroke patients is higher in community-based medical centers, but most of PSD patients are mild or moderate. More effective early intervention should be adopted to decrease PSD,promote the recovery of neural function and improve their quality of life.

Objective To analyze the expression feature and function of microRNAs in exosomes secreted by leukemia cells (LCEX). Methods The mice leukemia cell line L1210 was taken as the example, and LCEXL1210 was obtained by isolating supernate of L1210 cells through density gradient centrifugation. MicroRNAs isolated from LCEXL1210 were analyzed by microarray analysis, compared with miRNA from L1210 cell line, and then some of miRNAs with different expression were verified by real-time PCR and were analyzed by Gene Ontology (GO) database. Results The number of miRNAs identified in LCEXL1210 was 1 044, and that in L1210 cell line was 872. The number of shared miRNAs between LCEXL1210 and L1210 cell line was 732, accounting for 70.1 % of LCEXL1210 and 83.9 % of L1210 cell line, respectively, which indicated that 70 % of LCEXL1210 was derived from the parental cells. Interestingly, 312 miRNAs in LCEXL1210 were found to be underrepresented in the parental cells, indicating their specificity in LCEXL1210. Some miRNAs were significantly highly expressed in LCEXL1210 compared with those in L1210 cell line, including miR-16-1, miR-210, miR-195 and so on, which showed that miRNAs isolated from LCEXL1210 were differentially expressed with those from the parental cells. Some differentially expressed miRNAs from LCEXL1210 were verified by real-time PCR, and then were analyzed by GO database, which demonstrated that these highly expressed miRNAs participated in the processes of various biological function and signal transduction. Conclusions MiRNAs isolated from LCEXL1210 show a high similarity to miRNAs isolated from L1210 cells, whereas of which one-third are specific. The highly expressed miRNAs participate in the processes of various biological function and signal transduction.

Objective To investigate the distribution of eosinphililic neurons ( ENs),reactive astrocytes ( RAs),and infarction after transient cerebal ischemia,and the time profile of pathomorphological changes.Methods Unilateral forebrain ischemia was induced in Mongolian gerbils by two 10 minutes unilateral common carotid artery occlusions with a 5 hours interval.Laser Doppler flowmetry was used to detect intra-ischemic anterior cortex blood flow.Animals were sacrificed at 24 hours,4 days,2 weeks,4 weeks,16 weeks and the brain were prepared for pathomorphological assay.Results Intra-ischemic laser Doppler flowmetry show significant ischemia during carotid artery occlusion:22.1％ ± 9.5％,26.3％ ± 4.9％,37.5％ ± 3.5％,F =67.219,P ＜ 0.01 ; the decrease was significantly greater in the anterior cortex.ENs appeared in middle and deep layers at 24 hours postischemia,and ENs area extend to all layers of cortex by 4 days.Large areas of high EN density ( ≥80/mm2) evolved to infarcts between 4 days and 4 weeks.Posterior cortex evolved to low EN area ( ＜ 80/mm2) without transformation into infarcts.RAs were consistently distributed in areas with ENs,and RA areas with high EN density were largely transformed into infarcts between 4 days and 4 weeks. Delayed astrocytic death took place in the RA areas with high EN density.Conclusion Density of ENs is an important indicator of delayed astrocytic death and infarction in postischemic tissue.

Tumor immune microenvironment has been the focus of tumor research in recent years, and its role in tumor regulation has become prominent and has received increasing attention. The imbalance of the tumor immune microenvironment plays an important role in promoting tumor progression, and the adjustment of its instability plays an important role in controlling tumor progression. The theoretical idea of Traditional Chinese Medicine's "Yipingweiqi" is basically the same as that of modern medicine of controlling tumors by maintaining the balance of the immune microenvironment. This study discusses the aspects of tumor immune microenvironment, its destabilization, relationship to tumor progression, importance in Traditional Chinese Medicine, and regulation by Traditional Chinese Medicine with different treatments. In particular, this work focuses on the role of Traditional Chinese Medicine in maintaining the balance of the tumor immune microenvironment and its potential mechanism by using qi benefit, yang warming, dampness eliminating, and heat clearing under the guidance of the principle of "Yipingweiqi". Results will provide reference for the application of Traditional Chinese Medicine in the diagnosis and treatment of tumors.

OBJECTIVETo study the effects of Zhenqing Recipe (ZQR) and earthworm on the expressions of transforming growth factor-beta1 (TGF-beta1) and plasminogen activator inhibitor-1 (PAI-1) in renal tissues of type 2 diabetes mellitus (T2DM) rats.

METHODSThe T2DM model rats induced by high sucrose/fat feeding and low dose streptozotocin injecting were randomly divided into the model group, the ZQR group, and the earthworm group. A normal control group was also set up. ZQR extract was given at the daily dose of 24 g/kg body weight by gastrogavage to rats in the ZQR group. The earthworm extract was given at the daily dose of 2.6 g/kg body weight by gastrogavage to rats in the earthworm group. Equal volume of distilled water was given to rats in the normal control group and the model group by gastrogavage. The medication was once daily for 8 successive weeks. The fasting blood glucose (FBG), serum PAI-1, 24-h urinary albumin excretion (UAE), and endogenous creatinine clearance rate (CCr) were detected. The structural changes of renal tissues stained with Periodic Acid-Schiff were observed by light microscope. The expressions of TGF-beta1 and PAI-1 were analyzed by immunohistochemistry. And the mRNA and protein expressions of TGF-beta1 and PAI-1 in the renal cortex were detected by Real-time PCR and Western blot respectively.

RESULTSCompared with the normal control group, the FBG, serum PAI-1, UAE, the mRNA and protein expressions of TGF-beta1, and PAI-1 significantly increased in the model group, and CCr obviously decreased (P<0.01). Compared with the model group, FBG, serum PAI-1, UAE obviously decreased (P<0.01) and CCr obviously increased (P<0.05) in the ZQR group. FBG was not obviously lowered in the earthworm group. The serum PAI-1 and UAE both decreased obviously (P<0.05, P<0.01) and CCr increased (P<0.05) in the earthworm group. The effects of ZQR were superior to the earthworm. The renal pathological changes got improved in the ZQR group and the earthworm group. The mRNA and protein expressions of TGF-beta1 and PAI-1 significantly decreased in the ZQR group and the earthworm group, especially in the ZQR group.

CONCLUSIONSEarly application of ZQR and earthworm in treatment of T2DM rats with nephropathy was effective in protecting the kidney. Its mechanism may possibly be correlated with inhibition of TGF-beta1 expression, resulting in down-regulation of PAI-1 expression. ZQR showed better effects than earthworm.

Objective: To assess the effectiveness of radiofrequency ablation (RFA) in the treatment of multiple pregnancies. Methods: In this retrospective study, 84 cases (total 174 fetuses) of complex monochorionic pregnancies treated with RFA for selective fetal reduction were analyzed. All cases were managed in the Guangdong Women and Children Hospital from January 2015 to January 2018. Indications for offering RFA, details of the procedure and pregnancy outcomes were collected and analyzed. Results: (1)The rate of miscarriage and fetal intrauterine death was 21% (18/84), termination of pregnancy because of fetal malformation or oligohydramnion occurred in 10% (8/84) of cases. Total live birth rate was 69% (58/84) and the gestation age at delivery was (35.0±3.0) weeks. (2) The live birth rate of twin reversed arterial perfusion sequence (TRAPS) was the lowest (6/11), followed by twin to twin transfusion syndrome (TTTS; 66%, 27/41), structural or genetic abnormalities of one fetus in monochorionic twin pregnancy (10/14), triplet pregnancy reduction (4/6) and selective intrauterine growth restriction (sIUGR) (11/12). (3) The live birth rate was 67% (20/30) in stage Ⅲ of TTTS and 7/11 in the stage Ⅳ of TTTS (P>0.05). The average gestational age was (33.6±3.0) weeks in stage Ⅲ of TTTS compared with (36.5±2.4) weeks in the stage Ⅳof TTTS (P<0.05). Conclusions RFA appears to be a reliable option for selective fetal reduction in monochorionic multiple pregnancies. The indication of RFA is an influencing factor on its pregnancy outcomes. Type Ⅱand type Ⅲ sIUGR may choose this technique as a priority. Compared with stage Ⅲ of TTTS, the live birth rate and the gestation age at delivery in stage Ⅳ of TTTS, there are no significant differences.

Pulmonary embolism is the cardiovascular disease caused by endogenous or exogenous emboli blocking the pulmonary artery system. Pulmonary embolism is clinically very common and has a high recurrence rate. Its etiology is complicated. Pulmonary embolism recurrence can be caused by many factors, which affect its prognosis. Complicated diseases, residual thrombosis, anticoagulation therapy and respiratory disorders are the main factors that lead to pulmonary embolism recurrence. Some blood test indicators can also reflect the recurrence of pulmonary embolism. This paper reviews the risk factors and prevention strategies of pulmonary embolism recurrence, with the purpose of reducing recurrence rate, improving prognosis and thereby providing objective evidence for clinical practice.

Purpose: The main goal of this study was to analyze the prognosis of secondary oral squamous cell carcinoma (SCC) with a comparison with sporadic oral SCC by a matched-pair design. Materials and Methods: Records of patients with surgically treated primary oral SCC were reviewed, and a total of 83 patients with previous history of radiotherapy for nasopharyngeal carcinoma (NPC) were retrospectively enrolled. A matched-pair study was performed, each NPC survivor was matched with two sporadic oral SCC patients by age, sex, primary tumor site, adverse pathologic characteristics, disease stage, neck node status, and tumor stage. The overall survival (OS) and disease-specific survival (DSS) rates were calculated by the Kaplan-Meier method; independent prognostic factors were evaluated by the Cox proportional hazards method. Results: Compared with sporadic oral SCC patients, NPC survivors were less likely to be smokers (p=0.004), perineural invasion and lymphovascular invasion were more common in NPC survivors (both p < 0.001). The 5-year OS and DSS rates in NPC survivors were 47% and 54%, respectively; the 5-year OS and DSS rates in sporadic oral SCC patients were 62% and 67%, respectively; the difference was significant (both p < 0.05). In survival analysis, disease stage remained to be independent prognostic factor for both the OS and DSS. Conclusion NPC survivors had worse OS and DSS than sporadic oral SCC patients, NPC survivors were less likely to be smokers, but had higher opportunity of perineural invasion and lymphovascular invasion. Disease stage was the most important predictor for the survival in NPC survivors.
