ObjectiveTo study the influence of EmbryoGlue on the implantation of embryo and pregnancy outcome in vitro fertilization (IVF)-embryo transfer (ET).Methods From August 2010 to January 2011,243 infertile patients in Reproductive Medical Center of Tianjin Medical University General Hospital who underwent IVF or intracytoplasmic sperm injection (ICSI) were divided into two groups,including 129 cases used EmbryoGlue as the embryo transfer medium in experimental group and 114 cases used G-2 as embryo transfer medium in control group.Pregnancy outcome were compared between two groups.Results (1) The female age,IVF/ICSI constituent ratio,previous failure cycles and infertile factors of patients did not show statistical difference between experimental group and control group (P ＞0.05 ).(2) The implantation rate of women in experimental group increased significantly compared with the control group [ 30.4％ ( 85/280 ) vs.18.8％ ( 48/255 ),P ＜ 0.05 ] ; Clinical pregnancy rate increased significantly compared with the control group [48.8％ (63/129) vs.34.2％ (39/114),P ＜0.05] ; Multiple pregnancy rate increased significantly compared with the control group [ 34.9％ (22/63) vs.20.5％(8/39),P ＜ 0.05 ] ; Ectopic pregnancy rate decreased significantly compared with the control group [ 4.8％(3/63) vs.17.9％ ( 7/39 ),P ＜ 0.05 ].ConclusionEmbryoGlue can facilitate embryo implantation in IVF-ET and reduce the occurrence of ectopic pregnancy.

Objective Using the contents of naphthaquinine and shikonin as the indices,the influences of ultrasonic extraction and soxhlet extraction on the active constituents in Arnebia euchroma(Royle)Johnst.were studied.Methods An orthogonal design was applied.Naphthaquinine content was determined by spectrophotometry and shikonin content by HPLC.The extraction rate of the two extracting methods was compared to optimize the process condition.Results By using the two extracting methods,particle size had an obvious effect on the extraction rate of naphthaquinine(the bigger particle,the higher extraction rate),but had no effect on the extraction rate of shikonin;the solvent of ethanol showed different effects on the extraction rate of active constituents by using the two extraction methods,the extraction rate being higher by ultrasonic extraction while lower by soxhlet extraction.Conclusion Ultrasonic extraction is efficient,and with energy and time saving in extracting active constituents of Arnebia euchroma(Royle)Johnst.,which is superior to soxhlet extraction.

AIM: To investigate the effects of advanced glycation end products (AGEs) on protein and mRNA expression of macrophage inflammatory protein-1? (MIP-1?) in cultured human umbilical vein endothelial cells(HUVECs). METHODS: HUVECs were cultured with AGEs at different concentrations for 24 h and at a concentration of 400 mg/L for different time.The levels of mRNA and protein expression of MIP-1? in cultured HUVEC were detected by in situ hybridization and Western blot, respectively. RESULTS: In situ hybridization showed that after exposure of HUVECs to AGEs at different concentrations (100 mg/L, 200 mg/L, 400 mg/L) for 24 h, the average integrated optical density values (18.76?3.17, 26.58?1.61, 34.23?2.25) of MIP-1? mRNA expression in HUVECs were higher than that in control group (13.83?1.24, P

OBJECTIVETo investigate the risk factors of pinhole infection in the fractured lower limbs after external fixation.

METHODSThe case-control study was designed. From May 2009 to May 2014, the clinical data of 272 patients with lower limb fracture treated by external fixation device were collected. All the patients were divided into two groups according to post-operative pinhole infection. There were 29 cases in the case group including 23 males and 6 females. The age of patients in case group ranged from 25 to 77 years old,with the average age of (53.41 ± 12.77) years old. There were 243 cases in control group including 217 males and 26 females. The age of patients in the control group ranged from 27 to 78 years old, with the average age of (48.71 ± 11.87) years old. There were nine risk factors observed in our study including age, gender, fixed time by external fixation device, diabetes, time in bed, smoking, operation condition of other parts in the body, infection condition of other parts in the body.

RESULTSThe results of univariate analysis showed that there were statistically significant differences among age (χ² = 15.708, P < 0.001), fixed time by external fixation device (χ² = 11.940, P < 0.001), severity of the lower limb fracture (χ² =15.438, P < 0.001), diabetes (χ² = 8.519, P = 0.004) and time in bed (χ² = 7.165, P = 0.007) between case group and control group. The results of Logistic regression analysis showed that the risk factors of pinhole infection after fixed by external fixation device in the lower limb fracture were the advanced age (OR = 8.327, P < 0.001), fixed time by external fixation device (OR = 6.795, P < 0.001), diabetes (OR = 4.965, P = 0.001) and time in bed (OR = 4.864, P = 0.008).

CONCLUSIONThe advanced age, long fixed time, diabetes and long time in bed could increase the risk of pinhole infection after external fixation in the lower limbs with fracture.

Objective:This study analyzes the clinicopathological characteristics, pathological diagnosis, treatment, and prognosis of ovarian small cell carcinoma (SCCO). Methods:The medical records of SCCO patients in the Cancer Hospital of Peking Union Medical College between 2005 and 2012 were reviewed. Results:The mean age of patients was 43. 75 years old (ranging from 17 to 57), two cases were postmenopausal, and one case was less than 30 years old. Twenty-one patients had FIGO stageⅠ, whereas three cases had stageⅢto Ⅳ. Three cases were classified as pulmonary type. Forty-three patients received cytoreductive surgery, and one underwent fertili ty-conserving surgery. All patients were postoperatively treated with platinum-based chemotherapy, whereas three cases received Paclitaxel plus Carboplatin. No patient received adjuvant radiotherapy. One patient died nine months after the initial diagnosis, and one died 12 months after the initial diagnosis. The other two cases remain alive with no evidence of recurrence after follow up at 7 and 30 months after diagnosis. Conclusion:SCCO is a rare ovarian tumor with high malignancy potential and thus has poor prognosis. The clinical manifestations of SCCO resemble those of epithelial ovarian cancer. Immunohistochemistry can be used for differential diagnosis. The standard SCCO treatments are cytoreductive surgery and adjuvant platinum-based chemotherapy. The optimal chemotherapy regimen requires further research.

The aim of this study is to investigate the anti-inflammatory effect of the adenosine derivative N6-(3-hydroxylaniline) adenosine (WS070117M1) on cigarette smoke plus LPS (lipopolysaccharide)-induced chronic obstructive pulmonary disease (COPD) in mice and its mechanism. COPD model was established by exposing male BALB/c mice to cigarette smoke and challenged with LPS inhalation. Supernatants of bronchoalveolar lavage fluid (BALF) were harvested and IL-1β, IL-6, IL-8 and TGF-β1 levels were measured by ELISA (enzyme-linked immunesorbent assay). The number of total white blood cells and neutrophils in bronchoalveolar lavage fluid was counted separately. Lung tissue was stained with Mayer 's hematoxylin and eosin for histopathologic examination. pAMPKa protein expression and distribution of lung tissue were analyzed by immunohistochemistry method. In vitro, levels of AMPKα phosphorylation in phorbol-12- myristate-13-acetate (PMA) differentiated THP-1 cells was detected by immunohistochemistry, IL-8 level in supernatants of cigarette smoke condensate stimulating PMA differentiated THP-1 cells was measured by ELISA. The results showed that WS070117M1 treatment significantly activated AMPKa in the lung tissue. It also resulted in down regulation of IL-1β, IL-6, IL-8 and TGF-β1 levels in bronchoalveolar lavage fluid and IL-8 level in cigarette smoke condensate stimulating PMA differentiated THP-1 cells. In addition, WS070117M1 could inhibit the recruitment of total white blood cells and neutrophils. These results suggest that WS070117M1 may alleviate the airway inflammation by activating AMPK in the lung tissue.
