Research on the association between maternal periodontal disease and the risk of preeclampsia has generated inconsistent results. This meta-analysis was conducted to evaluate the association between maternal periodontal disease and the risk of preeclampsia. A literature search of PubMed and Embase was performed to identify relevant papers published before March 2013. Only observational studies that assessed maternal periodontal disease and the risk of preeclampsia were selected. Patients' periodontal status was examined at different time points during pregnancy or after delivery (at 14-32 weeks of gestation, within 48 h prior to or within 5 days after delivery). Pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated for cases and controls. Cases were defined as women with concurrent hypertension and proteinuria after 20 weeks of gestation. Eleven studies involving 1118 women with preeclampsia and 2798 women without preeclampsia were identified and analyzed. Women with periodontal disease before 32 weeks of gestation had a 3.69-fold higher risk of developing preeclampsia than their counterparts without periodontal disease (OR=3.69; 95% CI=2.58-5.27). Periodontal disease within 48 h prior to delivery was associated with a 2.68-fold higher risk of preeclampsia (OR=2.68; 95% CI=1.39-5.18). Pregnant women with periodontal disease within 5 days after delivery had a 2.22-fold higher risk of preeclampsia than women without periodontal disease (OR=2.22; 95% CI=1.16-4.27). In conclusion, this meta-analysis suggests that maternal periodontal disease is an independent predictor of preeclampsia.

AIM: To analyze the clinical features of children ocular penetrating trauma,and hope to effectively assist to prevent pediatric ocular trauma METHODS: The data of 145 cases (145 eyes) with ocular penetrating trauma,hospitalized in Xijing Hospital from January 2012 to December 2016,were collected and retrospectively analyzed.All the data of injury factors and environment,age and gender of patients,lesions,treatment and prognosis were detailed studied.RESULTS: In all the 145 pediatric patients with ocular penetrating trauma,accounted for 8.5% of all the ocular trauma patients,there were 95 cases of male,and 50 of female.Penetrating injuries mainly occurred in age of 3-9.The main injuries of ocular perforating in children were scissors,and sharp objects of wooden and iron.The wound was often located in the cornea or the anterior sclera.Traumatic cataract,vitreous hemorrhage and endophthalmitis were the common complications.The visual acuity was severely damaged,and 90 cases (62.1%) of the children recovered better than 0.1 after effective treatment.CONCLUSION: The visual function of pediatric p0atients was seriously threatened after penetrating injuries.However,the damage of vision and the rate of blindness can be reduced effectively after timely and correct diagnosis and treatment.It is the most important that active and effective prevention in keep children away from penetrating injuries.

To prepare anti-mouse uteroglobin binding protein (mUGBP) polyclonal antibody, two polypeptides were synthesized based on the bioinformatics analysis of mUGBP, and New Zealand white rabbits were immunized separately with each peptide coupled with keyhole limpet hemocyanin (KLH). The data indicate that a 13-amino acid polypeptide (positions 221st-233rd) was able to generate anti-peptide antibodies. The titer of the antisera detected with ELISA was 1:10(8). The antisera were then purified with immuno-affinity chromatography to obtain antibodies. Western blot analysis of mUGBP expressed as a fusion protein with a green fluorescent protein (GFP) was performed on the cell lysates of COS-1 cells with the purified antisera, suggesting that the antisera specifically recognized UGBP. By immunohistochemistry and indirect immunofluorescence analysis, we examined the expression of UGBP in the lung tissues from a patient undergoing surgical lung resection for a tumor and from normal mouse lung tissue, and found for the first time that UGBP protein was widely expressed in both mouse and human lung tissue with the most abundant expression in bronchial epithelial cells. These results suggest that the antigen epitopes of mUGBP are well predicted by using bioinformatics analysis. We have obtained anti-mUGBP polyclonal antibody, which will be useful for further investigation.

In recent studies some urea derivatives have been identified as potent anti-tuberculosis agents by targeting mycobacterial membrane protein large 3 (MmpL3). However, this compound series as exemplified by AU1235 exhibited poor in vitro pharmacokinetic profile. With AU1235 as the lead, we have identified a novel benzimidazole series as potential anti-tuberculosis agents by using scaffold hopping approach. Among these synthesized compounds, 2-aminobenzimidazole derivative 8b showed the potent anti-tuberculosis activity with the MIC value of 0.03 microg x mL(-1). This compound also showed improved metabolic stability compared to AU1235. Our investigation indicated that benzimidazole derivatives are the promising lead for further optimization as anti-tuberculosis agents.

AIM:To investigate the characteristic of T-cell acute lymphocytic leukemia 1 (TAL1) gene expres-sion in acute myeloid leukemia (AML) cell lines and in primary AML cells from de novo AML patients with different sub-types. METHODS:Real-time PCR was used to determine the expression of TAL1 mRNA in acute leukemia cell lines (Jurkat, CCRF-CEM, HL-60 and NB4 cell lines) and peripheral blood mononuclear cells from 47 newly diagnosed AML patients. Twelve healthy individuals were served as healthy control group. RESULTS:A significantly increased level in TAL1 mRNA was found in AML cell lines (HL-60 and NB4), T-cell acute lymphacytic leukemia (T-ALL) cell lines (Jur-kat, CCRF-CEM) and primary AML cells compared with the healthy controls. Over-expression of TAL1 was found in all detected AML subtypes, the highest level of TAL-1 mRNA was found in AML-M1 and AML-M5 subtype ( P <0.05). CONCLUSION:High expression of TAL1 in AML might influence the differentiation and proliferation of myeloid cells, further investigation needs to confirm whether it would be as a biomarker for pathogenesis of AML.

A new viral sampling concentration device was designed which was equipped with a new cationic filter membrane-Nanoceram suitable for field sampling. Norovirus Genegroup II was detected from environmental water with the aid of this device. The effects on virus recovery of prefiltration, various second-concentration methods, and different eluants were investigated through pre-experiment. The concentration optimized process, and the optimal concentration process were then determined. The results showed that the prefiltration had a profound effect on virus recovery, and two second-concentration method: PEG-NaC1 precipitation and celite adsorption, had almost the same concentration effects. The Na2 HPO4 solution of 0.15 mol/L was selected as the final eluant to elute the adsorbed Nuorovirus from the celite. The virus recovery of Nanoceram was determined to be 3.02%. Finally, successful detection of Norovirus GII in sewage from Yangqiao River, Fengtai District, Beijing was acheived. All these data had shown that the Naneceram filter concentration method could concentrate Norovirus from environmental water with a steady effects.

OBJECTIVETo investigate the antiinflammatory activities of aqueous extract of Occimum gratissmium (OGE) with emphasis on expression of proinflammatory cytokines in Lipopolysaccharide (LPS)-stimulated epithelial cell BEAS-2B.

METHODSEffects of OGE on cell viability were determined by MTT assay. mRNA expression were analyzed by and reverse transcription polymerase chain reaction (RT-PCR) and quantitative real-time PCR. Activation of kinase cascades was investigated by immunoblot. Intracellular reactive oxygen species (ROS) was analyzed by flow cytometry.

RESULTSOGE (<200 μg/mL) treatment or pretreatment and following LPS exposure slightly affected viability of BEAS-2B cells. Increase of interleukin (IL)-6 and IL-8 and the elevated level of intracellular ROS in LPS-stimulated BEAS-2B cells were diminished by OGE pretreatment in a dose-dependent manner. OGE suppressed inflammatory response-associated mitogen-activated protein kinases (MAPKs) and Akt activation. Additionally, OGE pretreatment increased level of cellular inhibitor of κBα (IκBα) and inhibited nuclear translocation of nuclear factor kappa B (NF-κB).

CONCLUSIONThese findings indicate that significant suppression of IL-6 and IL-8 expressions in LPS-stimulated BEAS-2B cells by OGE may be attributed to inhibiting activation of MAPKs and Akt and consequently suppressing nuclear translocation of NF-κB.

Objective: To collect, compare and analyze the changes in the strength and stability of the forearm Rou-Kneading manipulation before and after the training in Shaolin Neigong (internal Qigong). Methods: Ninety first-year undergraduates were randomized into three groups using the random number table method, with 30 people in each group. The Gongfa (Qigong method) group received training in both Shaolin Neigong and forearm Rou-Kneading manipulation. The manipulation group only received training in forearm Rou-Kneading manipulation. The control group only received training in forearm Rou-Kneading manipulation for one week. The ZTC-1 intelligent Tuina (Chinese therapeutic massage) manipulation parameter detection system was used to collect the wave crest, wave trough, and crest-trough difference of the strength and frequency of the forearm Rou-Kneading manipulation on the Z-axis (up and down), X-axis (left and right) and Y-axis (backward and forward) at weeks one, five and ten from the three groups. The collected data were then processed and analyzed. Results: The intra-group comparisons showed statistical significance in the Gongfa group and manipulation group (P<0.05). The strength and stability shown on the axes Z, X, and Y constantly grew with the increase of training time in the Gongfa group. The wave crest on the axes Z and Y steadily rose in the manipulation group, as well as the frequency on the axes Z, X and Y. The control group failed to show statistical significance in any of the three times of intra-group comparisons (P>0.05). The between-group comparisons showed statistical significance among the three groups at weeks five and ten (P<0.05). At week five, the wave crest on the axes Z, X, and Y, and the crest-trough difference on the axes X and Y were more prominent in the Gongfa group than in the manipulation group, showing statistical significance (P<0.05). At week ten, the wave crest, wave trough, and crest-trough differences on the axes Z, X, and Y were more prominent in the Gongfa group than in the manipulation group, presenting statistical significance (P<0.05). Conclusion: Practicing Shaolin Neigong can help the trainees reach the level of strength and frequency of Tuina clinicians in a shorter time in the forearm Rou-Kneading manipulation training. It can advance the efficiency in studying the forearm Rou-Kneading manipulation and promote the quality of the manipulation.
