Objective To evaluate the efficacy and safety of morphine by supersound atomizer for the management of postoperative pain in gynecology and obstetrics patients.Methods Eighty ASA class III patients scheduled for elective mixed gynecology and obstetrics surgeries were randomly and single-blindly located into 4 groups.Patients in each group received different analgesia therapy 30 rain before the end of the surgeries,as inhaling morphine 15 nag in group MI,inhaling morphine 20 nag in group M2,inhaling normal saline 10 ml in group N and intravenous patient-controlled analgesia (PCA) in group PCA.Open-label rescue analgesia of intramuscular injection pethidine 50 mg or intravenous PCA was also available as needed.Pain scores were measured at baseline,15 min,30 min,1 h,2 h,3 h,4 h,6 h,8 h and 24 h after the extubation using visual analng score ( VAS ),vital signs,adverse events,and the uses of rescue analgesia were also recorded.Results The VAS of group M2 were significantly lower than that of group N and group M1.The VAS at 15 min,1 h,6 h,8 h,24 h of group M2 were significantly lower than that of group PCA(P ＜ 0.05 or ＜0.01 ).The VAS at 15 min,30 min,1 h,2 h,4 h,6 h of group M1 were significantly lower than that of group N (P ＜ 0.05 or ＜ 0.01 ) postoperatively,which were significantly higher than that of group PCA except for 30 min.The morbidity of postoperative,nausea and vomiting in group M1 and group M2 were significantly higher than those in group N and group PCA.The rescue analgesia was more performed in group M 1 and group N than that in group M2 and group PCA.Conelusions Inhalation of morphine by supersound atomizer via intratracheal tube may produce safe and satisfying analgesic effect in postoperative pain model of gynecology and obstetrics patients.More studies are needed to determine what,if any,the optimum dose of morphine is for postoperative pain relieving and the possible mechanism.

To increase the biotransfomation efficiency from the orotic acid to the uridine 5'-monophosphate(UMP),URA5 gene encoding orotate phosphoribosytransferase was amplified from Saccharomyces cerevisiae BY4742 by PCR,then it was inserted into the expression vector pYX212(contained orotidine monophosphate decarboxylase gene URA3)and the pYX212-URA5 was transformed into Saccharomyces cerevisiae BJX12 by electroporation.The recombinant strain was elementarily used to convert orotic acid to UMP.The results showed that pYX212-URA5/BJX12 could accumulate 7mmol/L UMP from 32mmol/L orotic acid in 26h,significantly higher than both control groups pYX212/BJX12(2.7mmol/L) and BJX12(2.4 mmol/L).

Objective To observe the change of platelet activity marker in hypertensive patients complicated with ischemic cardiovascular and cerebrovascular disease ,and assess it s value in the happening of thrombotic disease. Method The platelet activity marker (CD62p,CD63) were measured by flow cytometry in 40 hypertensive patients complicated with ischemic cardiovascular and cerebrovascular disease (group C ),46 hypertensive patients not complicated with ischemic cardiovascular and cerebrovascular disease (group B),and 30 cases of healthy control (group A). Comparison between three groups were made. The serum fibrinogen were measured at the same time. Result serum level of CD62p, and CD63 in group B,C are higher than group A.(P

Objective To determine the function of toxic protein VapC in toxin/antitoxin system of Leptospira species and the cytotoxicity to host cells of the toxic protein.Methods Using genomic DNA of pathogenic L.interrogans serogroup Icterohaemorrhagiae serovar Lai strain Lai as the template,several PCRs were performed to amplify entire vapB,vapC and vapBC genes.Subsequently,the prokaryotic expression systems of vapB,vapC and vapBC genes were constructed.Expression of the target recombinant proteins rVapB and rVapC was detected by SDS-PAGE and the expressed rVapB and rVapC were extracted by NiNTA affinity chromatography.Activity of rVapB and rVapC to lyse the DNAs or RNAs from L.interrogans strain Lai and THP-1 cells were then determined.The changes of transcription and expression of vapB and vapC genes of L.interrogans strain Lai before and after infection of THP-1 cells were detected by real-time fluorescent quantitative RT-PCR and Western blot assay.The eukaryotic expression vectors of the vapB and vapC genes were generated for transfection of host cells and CCK-8 agent was used to detect the effect of leptospiral VapB and VapC proteins on activity of host cells.Results The nucleotide and putative amino acid sequences of the cloned vapB and vapC genes were completely identical with the reported corresponding genes.The constructed prokaryotic expression systems could express rVapB and rVapC,respectively.rVapC displayed RNase avtivity but did not lyse DNA.When L.interrogans strain Lai infected THP-1 cells,the transcription and expression of vapB and vapC genes were upregulated and partial VapC protein was secreted from the leptospiral cells.The mass mortality was observed in HEK293 human renal tubular epithelial ceils containing the vapC gene through transfection.Conclusion VapC protein of L.interrogans strain Lai is a RNase and is secreted during infection of host cells with obvious cytotoxicity.

Objective To study the effect of balloon dilatation therapy on dysphagia caused by cricopharyn- geal achalasia.Methods Ten cases of dysphagia were diagnosed as cricopharyngeal achalasia by videofluoroscopic swallowing study(VFSS).A 14~* urethral catheter was inserted into the esophagus and an amount of water was injec- ted into the balloon of the urethral catheter to make it turgid.Then the catheter was pulled upwards and passed through the stricture of esophagus to dilatate the cricopbarygeus muscle.Meanwhile,low frequency electrical stimula- tion was used and combined with functional training of the organs related to deglutition and ingestion.The results be- fore and after the treatment were evaluated.Results After 19.7 times of dilatation therapy,the content of water in- jected into the balloon was increased from 2.65?0.91 ml to 8.20?0.92 ml.Cricopharyngeal achalasia was alle- viated significantly(P

Objective To discuss the relationships between qi-arrival and mind-control, qi-arrival and qi-regulation, and to define qi-arrival by tracing the relevant records in Nei Jing (Classic of Internal Medicine) and Nan Jing (Classic of Difficult Issues). Method Thirty-seven relevant ancient books of the two classics were reviewed and the notes by WANG Bing, MA Shi, and YANG Shang-shan were referred. Result Mind-control requires the spirits of the practitioner, patient and environment, as well as observing and waiting for the arrival of qi. Regarding qi-regulation, theories involve that qi-arrival achieves same reinforcing and reducing effect as qi-regulation, qi-regulation is elucidated from the correct location of acupoint, proper needling depth and direction, and to regulate qi by observing the arrival of qi. Besides, the changes of internal and external environments also influence qi-arrival via qi-regulation and mind-control. Conclusion Qi-arrival is closely related to mind-control and qi-regulation in obtaining, differentiation, and adjustment. Mind-control and qi-regulation assist each other through the whole acupuncture process, which is the core of qi-arrival.

[Abstract ] Objective Numerous studies had shown that synaptic-associated proteins (SNAPs) were closely related to the occurrence and development of tumors .The aim of this study was to investigate the expression of synaptosomal-associated protein 47 (SNAP47) and its correlation with the clinicopathological features in non-small cell lung cancer(NSCLC). Methods The expres-sions of SNAP family (SNAP23, SNAP25, SNAP29 and SNAP47) were extracted and analyzed through the gene expression microarray and the cancer genome atlas ( TCGA) data-base.SNAP47 mRNA expression in 52 cases of lung adenocarcinoma and their correspond-ing normal tissues were detected by quantitative real-time PCR ( qRT-PCR) . Results Among 52 cases of lung adenocarcinoma , SNAP47 mRNA expression levels of 41 cases(78.9%) were significantly higher than the adjacent lung tissue (P<0.05).The mRNA level of SNAP47 was associated with lymph node invasion and advanced clinical patho-logical stage .The mRNA levels of SNAP47 of patients in II/III stage were significantly higher than those of I stage patients ( 6.558 ± 4.730 vs 2.718 ±2.370, P<0.05).The mRNA levels of N1+N2 were higher than those of N0 (6.609 ±4.942 vs 3.360 ±2.987,P<0.05). Conclusion The high specificity of SNAP47 expression in lung cancer tissues might be associated with the invasion and lymph node metastasis of NSCLC , which is the potential therapeutic target of lung cancer .
