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.

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 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 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.

The present study aims to investigate the kinetic histocytochemical changes of acupoints in different condition. The expression of tryptase (+) mast cells, histamine (HA) , serotonin (5-HT) and nociceptive neuropeptides including calcitonin gene-related peptide (CGRP) and substance P (SP) were observed by immunohistochemistry combined with confocal technology. Mast cells were labeled with anti-mast cell tryptase antibody and simultaneously with HA or 5-HT primary antibodies to observe their co-expression. The results showed that: (1) SP and CGRP were expressed more highly on the cutaneous nerve fibers of "Hegu" (LI 4) after acupuncture stimulation than that of the control. Mast cells aggregated in close proximity to the blood vessels in intra-epidermis and dermis, and some of them with degranulation in the lower dermis and subcutaneous tissue of "Hegu" (LI 4). Both mast cells and their granules appeared with HA (+) and 5-HT (+) expression at stimulated LI 4 sites, while a few intact mast cells with a little expression of 5-HT and HA were distributed in areas of non-stimulated Ll 4. (2) The acupoints in different locations such as Baihui (GV 20), Weishu (BL 21), Zhongwan (CV 12) and LI 4 had the same constituent but the contents were different. (3) The histocytochemical responses of acupoints sensitized by the Gastric mucosa injury (GMI) were also investigated. GMI resulted in neurogenic plasma extravasation by Evans Blue (EB) in the skin of the acupoints over the back and abdomen, which mostly occurred in the T9-T11 dermatomere. The EB extravasation dots just like acupoints sensitization appeared after GMI and disappeared gradually during the natural self-recovery of the gastric mucosa. More SP and CGRP positive nerve fibers were distributed in EB dots than in regions beside EB dots and in the control, mostly distributed in the nerve fibers around both the vessels and root of hair follicle. Mast cells also aggregated and degranulated to release algogenic substances of 5-HT and HA around the vessels in areas of the EB dots. Collectively the acupoints displayed the same histocytochemical responses due to either acupuncture stimulation or GMI. This may potentially be the histocytochemical basis in the local acupoints and acupoints displayed kinetic changes in different condition.
