Objective:To analyze the effects of espO gene knockout on the biological characteristics of enterhemorrhagic Escherichia coli (EHEC). Methods:Two-step methods mediated by the suicide plasmid pCVD442-Δ espO and plasmid pTrc99a were used to construct the espO gene-deleted strain (Δ espO) and the complemented mutant (CΔ espO), respectively. HeLa cells were infected with different EHEC strains to analyze the biological functions and lethal effects of espO gene during infection. Results:PCR, electrophoresis and gene sequencing showed that the Δ espO and CΔ espO mutants were successfully constructed. Compared with the wild-type strain, neither the Δ espO nor CΔ espO mutant showed significant difference in growth rate, indicating that the espO gene had no influence on the growth and replication of EHEC. Furthermore, EspO could activate the tumor necrosis factor receptor (TNF)-induced NF-κB signaling pathway, while the effector protein NleB could inhibit the process. EspO could not inhibit the death of HeLa cells induced by TNF or TNF-related apoptosis-inducing ligand (TRAIL) after EHEC infection. Conclusions:In this study, we successfully constructed the espO gene-deleted and complemented mutants of EHEC and preliminarily analyzed the interaction between espO gene and host cells and the effects of espO gene on cell apoptosis during infection, which provided reference for further research on the in vitro biochemical activity and in vivo pathogenic roles of EspO.

The present study aimed to investigate the effect and the mechanisms of Bu-zhong-yi-qi-tang (BZYQ) on Spleen-Qi deficiency rat's model using nuclear magnetic resonance (NMR) metabolomics and multivariate statistical analysis methods. The rat Spleen-Qi deficiency model was established as follows: oral administration of Radix Rhei extract, loaded swimming and starvation for 24 h. The body weight and motor behavior of the rats were measured and recorded once a week. BZYQ could significantly improve body weight and behavioral of Spleen-Qi deficiency model rats compared with the model group (P < 0.05, 0.01). After drug administration, the changes in the levels of endogenous metabolites in the spleen including decreasing lactate, taurine and hypoxanthine, increasing glutamate and scyllo-inositol compared with the model group. The metabolomics approach is an effective tool for the investigation of the pharmacologic mechanism of BZYQ and it is helpful to further research.

OBJECTIVETo investigate the effectiveness of surgical strategies for Shang Ring circumcision in the treatment of short frenulum praeputii in patients with redundant prepuce or phimosis.
METHODSTotally, 130 cases of short frenulum praeputii with redundant prepuce or phimosis were randomly assigned to an experimental group and a control group of equal number to receive Shang Ring circumcision, the former by transverse incision in the distal penis foreskin and pull-up of the interior board, and the latter by conventional transverse incision and longitudinal suture of the frenulum praeputii. Comparisons were made between the two groups in the surgical duration, intraoperative blood loss, 24 h postoperative pain visual analog score (VAS), postoperative complications, satisfaction with the penile appearance, and the quality of sexual life.
RESULTSThe surgical duration, intraoperative blood loss, 24 h postoperative VAS, postoperative sexual satisfaction, and satisfaction with penile appearance were (4.60 +/- 1.20) min, (2.61 +/- 1.81) ml, 1.73 +/- 0.76, 98.5%, and 98.5%, respectively, in the experimental group, as compared with (21.60 +/- 6.30) min, (11.10 +/- 3.40) ml, 5.37 +/- 1.84, 70.3% and 69.8% in the control, with statistically significant differences between the two groups (P < 0.05). The incidence rates of such major complications as wound dehiscence, infection, and moderate to severe edema were 1.5% (1/65), 3.1% (2/65), and 4.6% (3/65), respectively, in the experimental group in comparison with 12.3% (8/65), 15.3% (10/65), and 30.7% (20/65) in the control, with statistically significant differences between the two groups (P < 0.05). None of patients had any serious complications.
CONCLUSIONShang Ring circumcision by transverse incision in the distal penis foreskin and pull-up of the interior board, with its advantages of shorter operation time, less blood loss, mild pain, fewer complications, and higher satisfaction and acceptance of the patients, can be used as an safe and effective approach to the treatment of short frenulum praeputii.

OBJECTIVETo investigate the action targets of ginseng (GS) and Panax notoginseng (PN), Chinese herbs for benefiting qi and activating blood circulation, on angiogenesis signaling pathway (VEGFR-2-Ras-MAPK) in human umbilical vein endothelial cells (HUVEC).
METHODSTo block the signal pathway by turns, at the first, added the IC50 of VEGFR-2 inhibitor, SU5416, and detected its downstream signaling protein Ras, MAPK expression using Western Blot. Secondly, added the IC50 of the Ras inhibitor, FPP, and detected its downstream signaling protein MAPK expression.
RESULTSCompared with the control group, adding SU5416 made the Ras, MAPK expression significantly decreased (P < 0.05, P < 0.01); and adding FPP made the expression of MAPK significantly decreased (P < 0.01). Compared with the group treated by SU5416 alone, the expression of downstream signaling protein Ras, MAPK were significantly higher in the group treated by SU5416 plus GS and PN (P < 0.05, P < 0.01); same state also found in comparison MAPK expression between groups treated with FPP alone and FPP plus GS and PN (P < 0.05).
CONCLUSIONThe angiogenesis mechanism of GS and PN on HUVEC may be realized by increasing the protein expression of three key signals, VEGFR-2, Ras and MAPK, respectively.
