The cell-free plasma DNA (cfpDNA) has been suggested as a useful tumor marker for its quantitative and qualitative tumor-specific alterations that reflect the biological characteristics and the progression and outcomes of tumors.Therefore,it has been used as liquid biopsy to detect cfpDNA in peripheral blood for the diagnosis,monitoring of clinical effects,and prognosis of malignancies

Objective To survey gene expression profiles in nonlesional refractory temporal lobe epilepsy(TLE)and to further verify the difference of gene expression.thus to evaluate the possible molecular pathogenesis of this kind of epilepsy that can help to supply a new way for the diagnosis and treatment.Methods The TLE samples and control cases were studied by means of cDNA microarray consisting of 1 8 000 genes.Reverse transcription polymerase chain reaction(RT-PCR)Was performed to measure the expression alterations of SH3GL2.BTNN2A2 and KCNJ4 mRNA in temporal cortex samples from patients who had undergone temporal lobectomy surgery for intractable epilepsy.Tissue from 10 subjects who did not have epilepsy served as controls.Results The known genes differently expressed in those TLE samples involved immunity correlation factor genes,signal conduction genes,ion channel transportation genes;mitochondria function genes and SO on were identified.Among which.the expression of SH3GL2 mRNA Was significantly increased in epileptic brain(1.022±0.547)compared with the controls(0.446±0.171,t=-3.181).In TLE group(0.481±0.196),the expression of BTN2A2 mRNA was also significantly higher than that of control subjects(0.243±0.111,t=3.351).Compared with control group(O.795±0.112),the expression of KCNJ4 mRNA Was significantly decreased in TLE patients(0.438±0.178).Conclusions cDNA microarray is an efficient and high.throughout method to survey gene expression profiles in intractable temporal lobe epilepsy.The variation of those gene expressions might be a potential etiological agent for TLE that may offer a novel target for anticonvulsant therapy.

Objective To explore different socio-demographic and clinical characteristics for early onset patients (EOP) with psoriasis and late onset patients (LOP) with psoriasis in Chinese population and to provide scientific evidences for establishing comprehensive prevention and treatment strategy for psoriasis.Methods Cross-sectional study was performed.A total of 942 diagnosed psoriasis patients who paid a visit to outpatient clinic in a tertiary hospital in China from 12th September 2013 to 19th May 2015 was consecutively enrolled and investigated.Exploratory analysis was conducted to detect the association between disease onset age and patients features.Results Among 942 enrolled psoriasis outpatients,the average age was (40.6 ± 13.6) years with a range from 5 to 80 years.The sex ratio was 2.1 in favor of male.The most observed type of psoriasis in the present study was psoriasis vulgaris (98.3％).The average psoriasis area and severity index (PASI) for patients were 9.47 ±7.63.Comorbidity was combined in 20.2％ cases.Patients with EOP had a significantly higher likelihood of family history of disease.Compared EOP to LOP,LOP had a significantly higher likelihood of comorbidities involvement (P ＜ 0.05) and significant higher BMI index (P ＜ 0.05).Conclusions The present study supports the hypothesis that there are clinical differences between EOP and LOP in Chinese population.Both dermatologists and patients should pay more attention to psoriasis-associated features,such as family history and comorbidity diseases involvements.

Objective To explore the CT and MR features of malignant peripheral nerve sheath tumor (MPNST) of adults.Methods The CT and MRI findings of 20 patients of MPNST confirmed by pathology were analyzed retrospectively.Results Among 20 cases,the lesions were located in the lower extremities (n=4),shoulder and spine (n=4),abdomen (n=3),chest wall (n=2),mediastinum (n=2),breast (n=1),prostate (n=1),scrotum (n=1),scalp (n=1),left maxillary sinus and orbital bottom (n=1).Nineteen cases appeared as solid masses and 1 case appeared as diffuse lesion.The maximum cross section of the lesions were about 1.41 cm× 1.42 cm-17.10 cm× 18.08 cm.Sixteen cases were ill defined margin and 4 cases were well-defined margin.CT scan showed 14 cases were lower density or isodensity and with patchy inhomogeneous density.Multiple calcification were found in 2 cases and osteolytic destruction were found in 7 cases.Enhanced CT of 10 cases showed solid component and gradually delayed enhancement,while cystic lesion and necrosis were not enhancement.The tortuous arteries were displayed in 7 cases.Seven cases were performed MRI and the lesions appeared as hypo-intensity on T1WI and hypo-intensity on T2WI with obviously high intensity of cystic component.Enhanced MRI of 3 cases showed significantly heterogeneous enhancement,cyst and necrosis had no enhancement.MR dynamic enhancement of 1 case showed time-signal intensity curve was platform type.DWI showed high signal.Conclusion MPNST has certain CT and MR characteristics which are helpful to improve the diagnostic accuracy.

[Objective] To explore risk factors for ectopic pregnancy to provide basis for its prevention.[Methods] A case-control study was done on 180 cases of ectopic pregnancy treated in Deqing Chinese medicine hospital from January 2012 to December 2016 and another 180 cases of intrauterine pregnancy were as control who received artificial abortion in outpatient clinic during the same period. The data on the factors that might bring about ectopic pregnancy were analyzed by single-factorial and multi-factorial logistic regression. [Results] The multi-factorial analysis confirmed that the risk factors associated with ectopic pregnancy were prior abortion history, pelvic inflammation, ectopic pregnancy history, fallopian tube surgery history and others. [Conclusion] Ectopic pregnancy is associated with multiple factors, whose occurrence should be prevented and reduced by taking corresponding measures against it.

Objective To investigate effects of problem-based learning (PBL) and traditional learning (TL) on students' long-term memory and clinical practice ability. Methods Totally 79 5-year-program undergraduates of 2006, 2007, 2008 grade in school of clinical medicine of our hospital were randomly divided into PBL group (n=38) and TL group (n=41). The teaching effects were evaluated by two exams as well as teachers' subjective impression. SPSS 17.0 statistical analysis software was used;exam results were expressed as x±s; t test and rank sum test were used to analyze the exam results and subjective impression. α=0.05 was set as inspection level. Results In the second exam after 6 months, the mean exam scores were (76.66 ±5.94) and (73.59 ±5.74) in PBL group and TL group, without significant differences between the two groups (t=1.85, P=0.068). However, at clinical intern-ship stage, PBL group outperformed TL group based on the subjective evaluation (P=0.065, 0.277). Conclusion PBL can culture students' ability of problem-solving, but it is limited in culturing long-term memory.

BACKGROUND:It is particularly important to establish an ideal animal model of pulmonary fibrosis to investigate the underlying pathogenesis and screen effective drugs to prevent and control pulmonary fibrosis. OBJECTIVE: To establish a modified scheme of establishing mouse models that can reflect pulmonary fibrosis formation in humans. METHODS: Fifty-six male C57BL/6 mice were randomly divided into two groups: A (a single large-dose injection) and B (multiple smal-dose injections). Mice in group A were subjected to a single intravenous injection of bleomycin 200 mg/kgviathe tail vein; and mice in group B received intravenous injections of bleomycin 50 mg/kg via the tail vein per week, totaly for 6 weeks. 

Objective To study lymph node micrometastasis in N0 colorectal cancer patients and its clinical significance. Methods In this study, 548 lymph nodes obtained from 62 cases of No colorectal cancer undergoing curative operation were examined by fluorescent quantity polymerase chain reaction assay for the expression of cytokeratin 20 (CK20) mRNA. Results Micrometastasis was detected in 55 lymph nodes (10.0% ) of 24 cases (39%). According to lymph node anatomical locations, micrometastasis was identified in 15. 8%, 5.0% and 3.3% lymph nodes in group Ⅰ ,Ⅱ and Ⅲ (grouped by the distance from the tumor), respectively. Micrometastasis was correlated with invasion depth of primary tumor, but was notrelated to gender, age, tumor size, tumor site and differentiation. Conclusions The expression of CK20mRNA in lymph nodes in patients with No coloreetal cancer could be used to improve the accuracy of clinical staging, and provide information for rational adjuvant therapy.

OBJECTIVETo explore the effect of Ginkgo biloba extract (GBE) on the function of alveolar polymorphonuclear neutrophils (PMN) in severe acute pancreatitis (SAP) rats complicated with lung injury (LI).

METHODSForty-eight adult SD rats were randomly divided into three groups, i.e., the sham-operation group, the SAP group, and the GBE treatment group, 16 in each group. The SAP model was successfully induced by retrograde injection of 5% sodium taurocholate solution into the biliopancreatic duct. Rats in the sham-operation group only received flipping of the duodenum. Those in the GBE treatment group received GBE intervention based on SAP model. Equal volume of normal saline was given to rats in the sham-operation group and the SAP group. Rats were sacrificed at 6 and 12 h after operation respectively. The lung tissue was sampled to evaluate the LI score. The wet/dry ratio (W/D) of lung tissues was detected. The activity of myeloperoxidase (MPO) was measured. Alveolar PMN was harvested by bronchoalveolar lavage. The content of neutrophil elastase (NE) in bronchoalveolar lavage fluid (BALF) was measured by enzyme-linked immunoabsorbent assay (ELISA). The percentage of CD11b/CD18 double positive PMN was detected using flow cytometry. The expression of intercellular adhesion molecule-1 (ICAM-1) and NE protein in the lung tissue was detected by Western blot.

RESULTSCompared with the sham-operation group, significant pathologic lesion occurred in the lung tissue of rats in the SAP group; the pathologic LI score, lung tissue W/D ratio, MPO, and NE content in BALF significantly increased, the expression of ICAM-1 and NE in the lung tissue was obviously up-regulated, and the percentage of CD11b/CD18 double positive PMN significantly increased (P < 0.01). Compared with the SAP group, pathological lesion of the lung tissue was obviously attenuated, and the above indices were all significantly declined in the GBE treatment group (P < 0.01).

CONCLUSIONSExpression of ICAM-1 in the lung tissue and the percentage of D11b/ CD18 double positive PMN were up-regulated in SAP rats complicated with LI, resulting in the adherence of PMN to pulmonary vascular endothelial cells, and then activating PMN to release NE and aggravate LI. GBE could alleviate LI through down-regulating the expression ICAM-1 and CD11b/CD18, and hindering the adherence and activation of PMN to pulmonary vascular endothelial cells.
