Objective To further identify the isolated Mycoplasma genitalium (Mg) from the high risk population of STD in China. Mothods The morphology of Mg standard strains and clinical isolates were observed under electron microscopy (EM) and atomic force microscopy (AFM). Mg sample preparation for AFM was fixed on mica and AFM images of scanning observation were captured by contacting and tapping modes and operated under normal atmospheric pressure and temperature. Results and Conclusion Mg had a diversity of shapes, including flask, pear, spindle or round shape with projecting neck portion and slightly broadened terminal structure under EM. The morphologic features under AFM were similar to those observed by EM. The typical Mg showed shapes of flask and pear with noticeable narrow ring or mark in the neck portion. The size of Mg measured under EM and AFM was similar as well. Mycoplasma

Objective To observe the feasibility and safety of carotid artery stenting(CAS) for treating the patients with symptomatic carotid artery stenosis.Methods 60 patients who were diagnosed with symptomatic carotid artery stenosis by DSA were performed CAS.Among them, 52 cases were onset stenosis of carotid artery,8 cases were extracanical stenosis.The degree of stenosis was 50%~70% in 14 patients,70%~90% in 28 patients and≥90% in 18 patients.64 stents were placed,and 15 filter protection devices were used.Results The drgree of stenosis was decreased from (73.4?9.5)% to (12.5?8.2)%. The plaques were disappear in 53 cases, many debris were found in 5 filter protection divices. The clinical symptoms of all patients were disappear within one week, the mild paralyse was recover in all patients. There were 53 cases with heart rate slowdown during or after operation,the blood pressure declined in 48 cases,and there were 5 patients with vasospasm, as well as one case with cerebral embolization,one case with sydrome of high perfusion and one case with sydrome of low perfusion or swoon. During flowing up for 3 months to 2 years,no one case was found TIA or cerebral infarction,however,only one case was found mild restenosis by DSA.Conclusions CAS is a safety and efficient method for treatment symptomatic carotid artery stenosis. Lowering the risk of operation is done by handling indication seriously and operation skillfully.

BACKGROUND: Many animal and clinical studies have reported that the safe and effective usage of umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs) transplantation for treatment of neurological genetic diseases.OBJECTIVE: To investigate the feasibility and effect of UCB-MSCs transplantation in the treatment of spinal muscular atrophy (SMA).METHODS: A child admitted at January 2010 had been confirmed as having SMA, and drug and rehabilitation therapies were invalid. Then, the child received UCB-MSCs transplantation via the first intravenous infusion and three times of subarachnoid injection, once a week, (4-6)×107 cells once and four times as a course. Neurological physical examination, biochemical test, muscle enzymes detection, FIM scoring and electromyography (EMG) examination were conducted. RESULTS AND CONCLUSION: Compared with prior to transplantation, the level of muscle enzymes decreased, FIM scores were increased from 68 to 93 points, EMG results showed that the motor units with re-contraction in each 10.0 ms were increased that the motor function was improved, the lower extremity muscle strength elevated, and the self-care ability was improved in the SMA child at 6 months after transplantation. During the 10-month follow-up, the child had no adverse effects. It is indicated that UCB-MSCs transplantation is effective to treat SMA, and the neurological function has a remarkable restoration.

Objective To assess the efficacy and safety of different dosages of oxycodone plus acetaminophen for treating acute pain after oral surgery,in order to provide a reasonable dosage of combination in clinic. Methods Randomized controlled trials ( RCTs ) on effect of combination of oxycodone plus acetaminophen on pain relief after oral operation were searched from the following data-bases:PubMed,EMbase,MEDLINE ( Ovid) ,the Cochrane Library,CNKI,and WANFANG from the date of their establishment to January 2015. The data of RCTs meeting the inclusive criteria were extracted according to Cochrane methods by two reviewers independently,and after the quality was evaluated and cross-checked,meta-analyses were conducted using RevMan 5.2 software. Results A total of 11 studies in 10 literatures involving 1 028 patients were included and were designated to 3 different dosage groups (5 mg/325 mg,10 mg/650 mg,10 mg/1 000 mg,respectively). The results of Meta-analyses showed that pain remission rate was significantly higher in the 3 different dosages of oxycodone plus acetaminophen groups than in the placebo group (RR5 mg/325 mg=3.35,95%CI [1.74,6.45],I2=38%,P=0.000 3;RR10 mg/650 mg=6.88,95%CI [4.00,11.83],I2=0%,P<0.000 01;RR10 mg/1 000 mg=4.94,95%CI [3.23,7.56],I2=81%,P=0.005). In additional,the RR of oxycodone 10 mg/acetaminophen 650 mg and placebo groups for pain remission rate was higher than that of the other 2 dosages groups,moreover,more studies were enrolled and its low heterogeneity led to high reliability. Usage rate of remedial painkillers was significally lower in oxycodone plus acetaminophen groups than in the placebo group (RR5mg/325mg=0.71,95%CI [0.60, 0.85],P<0.000 01;RR10mg/650mg=0.50,95%CI [0.41,0.61],P<0.000 01;RR10mg/1000mg=0.77,95%CI [0.66,0.90],P=0.001) ,In addition, the RRs of usage rate in oxycodone 10 mg/acetaminophen 650 mg and placebo groups were significantly lower than the other 2 dosages groups. Incidence rates of adverse effects were similar in the 3 different dosages groups and higher than that of the placebo group. However,the adverse events were generally described as mild to moderate in severity and rarely led to drug withdrawal according to all reports in the studies ( only one event ) . Conclusion The present study showed that combination of oxycodone plus acetaminophen can provide better analgesia in acute pain after oral surgery with high safety. In addition,combination of oxycodone 10 mg plus paracetamol 650 mg may be better for acute pain relief after oral surgery.

Objective To investigate the differences in eNOS gene expression,activity and its metabolites before and after human bone marrow mesenchymal stem cells (hBMSCs) are induced into vascular endothelial cells.Methods hBMSCs were induced into vascular endothelial cells.The morphological changes of the cells were observed under inverted microscope.Transwell assay was used to detect the cells' migration ability.The protein expression of eNOS was detected by immunofluorescence and Western blot.The activity of eNOS was detected by ELISA and the content of NO in cell culture supernatant was determined by nitrate reduction method.Results Compared with those in the undifferentiated group,the morphological changes of the differentiated cells were obvious.Cell migration ability increased by 238.10% (73.000±7.002 vs.21.000±4.359,P<0.05).The expression of eNOS protein increased by 114.72% (0.423±0.011 vs.0.197±0.079,P<0.05).The activity of eNOS was enhanced by 157.49% (4.967±0.073 vs.1.929±±0.103,P<0.05).The synthesis and release of NO increased by 155.67% (184.909±1.853 vs.72.323±0.426,P<0.05).Conclusion After hBMSCs are induced into endothelial cells,the expression of eNOS gene increases,their activities increase,synthesis and release of the metabolite NO increase.It may provide a basis for prevention and treatment of cardiovascular diseases with stem cells.
