0.05). There were no adverse events or severe adverse events in all these 72 cases. Conclusion Ozone is effective and safe in the treatment of bacterial vaginosis.

Objective To evaluate our experience of minimal access parathyroidectomy for primary hy-perparathyroidism (PHPT) caused by parathyroid adenoma. Methods From Jan 2000 to Jan 2009, clinical data of 28 cases of PHPT treated by minimal access surgery were analyzed retrospectively. Results All patients except 3 had severe clinical manifestations, serum calcium and parathyroid hormonal (PTH) of all the cases were elevat-ed. The rate of accuracy of preoperation localization by the sestamibi scan combined with ultrasound was 100%.The pathological diagnoses of all the 28 cases were uni-gland parathyroid adenoma. Within the follow-up of 6 months, no case suffered complication and recurrence, the levels of serum calcium were normal or decreased slightly, and the levels of PTH were normal or elevated slightly but no higher than 2 times of normal PTH level. Conclusions Preoperative localization is very helpful by using combination of sestamibi and ultrasound scan. Minimally invasive parathyroidectomy is a kind of improving procedure for the localized parathyroid adenoma.

Objective To evaluate a new suture coil in endoscopic submucosal dissection (ESD). Methods Data of 15 patients with early gastrointestinal cancer undergoing ESD were retrospectively ana?lyzed. The edge of the lesion was pulled up by the new coil?assisted suture for the submucosal layer to be full?y revealed, then the submucosa were dissected,and the wound was stitched by suture coil. The success rate and complications were evaluated. Results The lesions were successfully resected in 15 patients. By pull?up, the submucosal blood vessels were completely revealed. No intraoperative uncontrollable bleeding oc?curred. Small perforation occurred in one patient, and was well stitched by the suture coil. The pull?ups were successfully completed in all patients, and the operation time was 5?10 min. The intraoperative slippage of fixed titanium clips occurred in two cases. All the wounds were stitched. Minor bleeding happened in 1 pa?tient, and was controlled by hemostatic clip. Conclusion The new suture coil is easy to use,and can effec?tively prevent and deal with the occurrence of intraoperative and postoperative ESD?related complications.

Objective To investigate the effects of Tong Xin-Luo on cultured human umbilical vein endothelial cells (HUVECs) impaired by Lysophosphatidylcholine.Methods The herbage-contained serum of TXL was prepared,HUVECs were cultured in vitro.The study was designated to 4 group:normal control,LPC group,TXL group,and TXL + LPC intervened group.The cell function was determined by cell morphology and MTT colorimetric assay.Results Compaired with normal control group (0.380 ±0.023 ),LPC ( 0.320 ± 0.024 ) could significantly decrease the cells activity,promote cells death ( P ＜0.05 ).After TXL intervened(0.424 ±0.034),cells activity was significantly increased,cells death was d significantly decreased( P ＜0.05 ).Conclusions Tong Xin-Luo could protect human umbilical vein endothelial cells function by against the LPC-induced damage.

Sperm ultrastructural abnormalities are often associated with sperm motility, the integrity of genetic material, and the fertilization potential. The investigation of sperm ultrastructural abnormalities is based on the evolution of microscopy techniques. In his paper, we review the improvement of the microscopy techniques and the ultrastructure of several specific morphological defects and he apoptotic spermatogenic cells in order to expound the significance of sperm ultrastructural observation in clinical practice. We deem it necessary to analyze the sperm ultrastructure before exploring the pathology and adopting assisted reproductive technology for some special patients with teratozoospermia.

Objective To investigate the distribution of neurons expressing Fos protein in central nervous system (CNS) following esophageal mucosal acid exposure,and to map the contribution of spe- cific brain areas in sensitizing responsivity and emphasize the coding change of CNS to the esophageal acid stimulation.Methods Thirty-six healthy Sprague-Dwley rats were randomly divided into five groups. Group A (n=6) was normal group of home cage control animals to which no stimulation was given. Group B (n=7) was saline group which received esophageal perfusion with normal saline solution (0.9% NaCl).Group C (n=8) was treated with esophageal mucosal acid exposure containing 0.1 mol/L HCl. Group D (n=7) was sensitized by ovalbumin.Group E (n=8) received basal ovalbumin-sensitization plus esophageal mucosal acid exposure.The rat model of esophageal visceral hypersensitivity was estab- lished by the basic ovalbumin-sensitization combined with intra-esophageal mucosal acid exposure.The neuronal expressions of c-fos proto-oncogene were detected with immunohistochemical counter-staining and computerized color image analyzer under various conditions.Results The rats in model group with basic ovalbumin-sensitization plus esophageal acid perfusion initiated a high density expression of c-fos- immunoreactive(Fos-IR) neurons in multineuronal networks.A significantly higher number of Fos positive neurons was found in the model group than those in the corresponding regions of other groups (P＜0.05) in the following brain areas:frontal and parietal cortex,insular cortex,cingulated cortex,central amyg- daloid nucleus,the K(?)lliker-Fuse nucleus,the nucleus ambiguus,parabrachial nucleus,hypothalamic paraventricular nucleus,paraventricular thalamic nucleus,paratrigeminal nucleus,the nucleus of solitary tract,area postrema,reticular nucleus of medulla,whereas no significant difference was found in the dorsal motor nucleus of the vagus,supraoptic nucleus,periaqueductal gray matter or orbital part of infe- rior frontal gyrus.The values of Fos-IR neurons were also increased in the central amygdala,parabrachi- al nucleus,paraventricular nucleus,the paratrigeminal nucleus and NTS in the model group than that in the corresponding regions of other groups (P＜0.05).Conclusion The basic ovalbumin-sensitization fa- cilitated dramatically the c-fos expression evoked by esophageal acid perfusion,suggesting that visceral hypersensitivity induced by ovalbumin may alter cortical reactivity processing of esophageal acid stimula- tion in brain areas.

Asparaginyl endopeptidases (AEPs) in plants belong to the family of cysteine protease that undergo self-activation in the form of zymogen in acidic vacuole and play important physiological roles in maturation of seed storage proteins, protein degradation, programmed cell death and host defense. Bioprocessing enzymes (peptidyl Asx-specific ligases, PALs) that promote the maturation of cyclotides have recently been isolated and identified from several cyclotide-rich plants. PALs derived from AEPs can site-specifically catalyze the formation of asparagine or aspartate peptide bonds. Due to the advantages of relatively traceless peptide bonds and broad substrate spectrum and high catalytic efficiency, they have been playing important roles in the cyclization and modification of peptides and proteins, and are powerful tools for improving the stability of peptide drugs. This review describes the physiological functions of AEPs in plants and summarizes the discoveries, structural characteristics, catalytic mechanism and protein engineering of PALs, as well as the limitation of their applications and future trends. In addition, the applications of PALs in cyclotides biosynthesis and the development of macrocyclic peptides are highlighted, with the aim of providing a new idea for the biocatalytic synthesis of cyclic peptides.

There are several special advantages of the application of standardized patients ( SPs) in the assessments of clinical skills examination of medical practitioners .However , this application in China is restricted by some limit factors, such as the shortage of SP trainers and SPs , the huge funds needed and the imbalance of regional develop-ment.The suggestion to overcome those limitation and to promote SPs be applied to the clinical skills examination of medical practitioners are as follow: the preparatory of regional university union of SPs , the introduction of social capital to participate in and the adoption of the mode of scale operation .
