Objective To detect the expression of interleukin (IL)-27,-35 and their common subunit Epstein-Barr virus-induced gene 3 (EBI3) mRNA in peripheral blood from patients with psoriasis vulgaris (PV).Methods Peripheral blood was collected from patients with psoriasis vulgaris (PV) in progressive (n =22),stationary (n =20) and regressive (n =20) stage as well as 30 healthy human controls.A competitive enzymelinked immunosorbent assay (ELISA) was performed to determine the serum level of IL-27 and IL-35.SYBR Green-based real-time reverse transcription (RT)-PCR was carried out to measure the mRNA expression of EBI3 in peripheral blood mononuclear cells (PBMCs).Results The patients with psoriasis vulgaris showed a higher level of IL-27 and IL-35 compared with the healthy controls.The serum level of IL-27 was significantly higher in the patients with progressive,stationary and regressive psoriasis vulgaris than in the healthy human controls ((226.72 ±71.32) ng/L,(160.80 ± 20.02) ng/L and (181.93 ± 27.36) ng/L vs.(138.66 ± 33.93) ng/L,P＜ 0.01,0.05,0.01,respectively),and higher in the patients with progressive and regressive psoriasis vulgaris than in those with stationary psoriasis vulgaris (P ＜ 0.01,0.05,respectively).Increased serum level of IL-35 was observed in the patients with regressive psoriasis compared with those with progressive and stationary psoriasis and healthy controls ((355.78 ± 49.82) ng/L vs.(309.36 ± 36.10) ng/L,(299.14 ± 31.98) ng/L and (292.43 ± 36.26) ng/L,all P ＜ 0.01),while no statistical difference was observed between the patients with progressive and stationary psoriasos and healthy controls.The mRNA expression level of EBI3 in the patients with progressive,stationary and regressive psoriasis was 20.15,16.17 and 19.74 times,respectively,higher than that in the healthy controls.Conclusion IL-27,IL-35 and EBI3 may function as anti-inflammatory factors in the development,as well as the reversal of progression,of psoriasis.

BACKGROUND: Recently, miR-378 has been shown to modulate the anti-hypoxia capacity of bone marrowmesenchymal stem cells (BMSCs) and reduce cell apoptosis under hypoxic conditions.OBJECTIVE: To investigate the benefits of miR-378-upregulated BMSC transplantation in a rat model of acutemyocardial infarction.METHODS: Primary rat BMSCs were cultured in vitro. Until passage 3, the cells were infected with the lentiviruscarrying synthetic miR-378 gene fragments. A rat model for acute myocardial infarction was constructed by ligatingthe left anterior descending artery. Thereafter, the animals were randomly assigned to three groups: control group(n=10), BMSCnull group (n=16) and BMSCmiR-378 group (n=16). In the latter two groups, 50 μL of normal salinecontaining 1×107 empty virus-transfected or miR-378-transfected BMSCs was injected into the region of myocardialinfarction, respectively. Only 50 μL of normal saline was injected in the control group. Twenty-four hours later, theapoptosis of transplanted BMSCs was evaluated with TUNEL, and expression level of vascular endothelial growthfactor and transforming growth factor-β was detected using western blot assay. Four weeks after treatment, the leftventricular function of rats was assessed by echocardiography, and then histological and molecular biology analyseswere performed.RESULTS AND CONCLUSION: At 24 hours postoperatively, there were less apoptotic BMSCs and higher expressionlevels of vascular endothelial growth factor and transforming growth factor-β in the BMSCmiR-378 group than in theBMSCnull group (n=6, P < 0.001). Four weeks later, there were more transplanted BMSCs and BMSCs-derivedcardiomyocytes in the BMSCmiR-378 group than the BMSCnull group (n=10, P < 0.001). Moreover, increased new vesseldensity (P < 0.001), decreased infarcted area (P < 0.001), preserved left ventricular ejection fraction (P < 0.05), reducedleft ventricular end-diastolic volume (P < 0.05) were found in the BMSCmiR-378 group, compared with the other two groups.The above parameters were better in the BMSCnull group than the control group (P < 0.05). Overall, the upregulation ofmiR-378 could enhance the capability of BMSCs against hypoxia, and consequently promote myocardial repair afterimplantation, providing a new strategy for cell therapy of myocardial infarction.

Objective To clarify diagnostic value of C-reactive protein (CRP) in the pathological types of acute appendicitis in children and the role of CRP as a surgical indication marker for appendicitis.Methods Two hundred and six patients who underwent appendectomies and had pathologically confirmed appendicitis were reviewed between January 2010 and February 2014,and they were divided into gangrenous appendicitis group(n =53) and non-gangrenous appendicitis group(n =153) by postoperative pathological type.The correlation between preoperative clinical factors and the actual histological severity,and identify surgical indication markers were assessed by multivariate analysis and ROC analysis.Results There were significant differences in white blood count(WBC),neutrophils percentage and CRP level between gangrenous appendicitis group and non-gangrenous appendicitis group(P ＜ 0.05).Multivariate analysis showed that the level of CRP should be a risk factor for judging gangrenous appendicitis.It showed that the role of CRP in judging gangrenous appendicitis was superior to the proportion of neutrophils and WBC in the ROC curve.The ROC curve showed that the area under the ROC curve for the CRP level,neutrophils percentage and WBC was 0.931,0.659 and 0.599 respectively,and the optimal cut off value of CRP for surgical indication for classifying cases was around 44.4 mg/L,and the sensitivity was 75.5 ％,specificity was 93.5 ％.Conclusion The level of CRP is useful in identifying the pathological types of acute appendicitis in children,and can be considered to be a surgical indication marker for acute appendicitis in children.

BACKGROUND: At present, international classification of diseases by WHO, cerebrovascular disease classification used in China and TOAST classification used abroad are all based on patho-physiology. There is no report about human cerebral infarction by magnetic imaging types in Beijing and other areas.OBJECTIVE: To analyze retrospectively the subtype distribution of acute cerebral infarction of patients in Beijing by magnetic resonance imaging in order to make Beijing patients with acute ischemic stroke receive more exact and individualized treatment.DESIGN: Retrospective case study.SETTING: Department of Neurology, General Hospital of Beijing Military Area Command of Chinese PLA.PARTICIPANTS: The study was carried out in General Hospital of Beijing Military Area Command of Chinese PLA, Beijing Sino-Japan Friendship Hospital, Beijing Chaoyang Hospital, Beijing Naval General Hospital and Beijing Jishuitan Hospital between January and December 2004. Totally 602 inpatients with ischemic stroke who received treatment in each hospital were recruited. They were 352 male and 250 female with average age of (65.6±10.2) years.METHODS: The 602 patients with acute ischemic cerebral stroke who received the treatment in the 5 hospitals from Dongcheng, Xicheng,Chaoyang and Haidian districts in Beijing were recruited in the study. According to results of magnetic resonance imaging of brain, the maximal infarction area were determined. The patients were classified as: large infarction: over 1 lobe of brain, ＞ 5.0 cm in diameter; moderate infarction: less than 1 lobe of brain, 3.1-5.0 cm; small infarction: 1.6-3.0 cm; lacunar infarction, ＜ 1.5 cm.MAIN OUTCOME MEASURES: Constitution ratio of MRI classification of patients in each groupRESULTS: Totally 602 patients with ischemic stroke participanted in final result analysis. Among the patients with acute cerebral infarction of 5 hospitals in Beijing, 280 (46.5%) suffered from lacunar infarction, 299(38.1%) from small infarction, 57 (9.4%) from moderate infarction, and 36 (6%) from large infarction. There were significant differences between lacunar infarction and other types (P ＜ 0.01).CONCLUSION: Acute cerebral infarction of patients of Beijing mostly occurs in the type of lacunar infarction. It suggests that small arterial diseases are the major disease type of ischemic stroke in Beijing. This MRI classfication can be used for early classification, treatment guidance, evaluation and prognosis of acute ischemic cerebral stroke.

Objective To explore the effects of narrow-band ultraviolet B (NB-UVB)on the serum levels of thymic stromal lymphopoietin (TSLP)and interleukin-25 (IL-25), as well as on the expressions of TSLP receptor (TSLPR)and IL-25 receptor (IL-25R)mRNAs in peripheral blood mononuclear cells (PBMCs)from patients with atopic dermatitis(AD). Methods A total of 40 patients with AD and 30 healthy volunteers were enrolled in this study. All the patients were treated with NB-UVB at 0.3 - 2.5 J/cm2 thrice a week for 12 consecutive weeks. Venous blood samples were obtained from these patients before and after the treatment as well as from these healthy controls. Double-antibody sandwich enzyme-linked immunosorbent assay (ELISA)was performed to detect serum levels of TSLP and IL-25, and reverse transcription PCR(RT-PCR)to determine the mRNA expression levels of TSLPR and IL-25R in PBMCs from these subjects. The scoring atopic dermatitis (SCORAD)system developed by the European Task Force on Atopic Dermatitis was used to estimate the severity of AD, and visual analogue scale (VAS)to evaluate the degree of itch. Statistical analysis was carried out by the two-independent-sample t-test for intergroup comparisons and paired t-test for comparisons between pre- and post-treatment samples from these patients. Results After the treatment with NB-UVB, the total response rate reached 75%(30/40)in these patients, with a significant decrease in SCORAD score from 55.26 ± 10.88 before the treatment to 20.36 ± 5.12 after the treatment (t = 10.29, P < 0.05)and in VAS score from 8.20 ± 1.37 to 3.05 ± 1.02(t = 8.16, P < 0.05). Before the treatment, the patients showed a significant increase in the serum levels of TSLP(198.24 ± 29.47 ng/L vs. 120.13 ± 19.65 ng/L, t = 29.70, P < 0.05)and IL-25(160.54 ± 34.89 ng/L vs. 120.41 ± 43.07 ng/L, t = 14.65, P < 0.05), as well as in the mRNA expression levels of TSLPR (8.57 ± 1.34 vs. 1.94 ± 0.39, t =7.07, P < 0.05)and IL-25R(6.81 ± 0.50 vs. 1.48 ± 0.47, t = 18.89, P < 0.05)compared with the healthy controls. With the improvement of conditions after the treatment, a significant decrease was observed in the serum levels of TSLP (151.87 ± 14.78 ng/L, t = 18.56, P < 0.05)and IL-25(130.52 ± 29.65 ng/L, t = 9.07, P < 0.05), as well as in the mRNA expression levels of TSLPR (2.89 ± 0.53, t = 5.21, P < 0.05)and IL-25R (3.90 ± 0.37, t = 7.35, P < 0.05)in PBMCs from these patients compared with those before the treatment, and differences disappeared in all of these parameters between the patients and controls (all P > 0.05). Conclusions TSLP and IL-25 may play important roles in the development of AD, and NB-UVB may treat AD by downregulating the expressions of them and their receptors.

Objective To investigate the follicle development and pregnancy in clomiphene citrate-resistant patients with polycystic ovary syndrome (PCOS) after transvaginal follicular aspiration and gonadotropin administration. Methods Seventeen clomiphene citrate-resistant patients with PCOS failed to gonadotropin treatment associated with ovarian hyperstimulation syndrone(OHSS). They are anovulatory infertility with normal tubal and husbands'sperm condition. In this treatment regimen,all patients was administered with gonadotropin from day 5 of menstrual cycle(or withdrawal bleeding) and were asked to undergo ultrasound-guided transvaginal follicular aspirations for 5 days later. Only one or two follicles for every ovary were remained and gonadotropin administration was continued. A follicle development,ovulation rate,pregnancy rate and sex hormone were monitored. Results Fifteen of the 17 patients experienced dominant follicles development and ovulation. 9 of them with one(52.9%) ,4 with two(23.5%) and 2 with three(11.8%) dominant follicles ovulated and pregnancy occurred in 7 patiends(41.2%). All of pregnancy are singleton. Conclusion A single follicle development and singleton pregnancy can be realized in clomiphene citrate-resistant PCOS patients by combined ultrasound-guided transvaginal follicular asperation with gonadotropin administration.

Objective To assess the effectiveness of follicular aspiration in selection phase of follicle growth of the patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization-embryo transfer(IVF-ET). Methods Thirteen infertile patients with PCOS who previously failed IVF-ET associated with ovarian hyperstimulation syndrome (OHSS) , served as control group, were asked to undergo new IVF cycles (follicular aspiration group) with ultrasound-guided transvaginal follicular aspirations in the selection phase ( diameter9 - 10 mm) of follicle growth,with a total of 13 cycles both. No more than 10 follicles were selected. Clinical and endocrinological parameters were monitored. Results In follicular aspiration group, the average number of follicle 5; 12 mm in diameter and serum estradiol level were 16 ? 4 and (9899 ? 1431) pmol/L respectively, which were significantly lower than 29 ? 8 ( P
