Objective To observe the adverse reaction of dexmedetomidine(Dex)combined with dezocine in gynecological laparoscopic surgery after general anesthesia.Methods 120 cases of gynecologic laparoscopic surgery,ASA Ⅰ-Ⅱ,according to random number table method were divided into three groups,40 cases in each group.A group was intravenously injected Dex 1μg/kg 10min before induction,intravenously injected dezocine 5mg+ ondansetron 4mg 30min before the end of the operation.B group was intravenously injected dezocine 5mg+ ondansetron 4mg 30min before the end of surgery.C group was intravenously injected saline 1mL+ ondansetron 4mg.Before induction(T0),5min before extubation(T1),extubation(T2),10min after extubation(T3),the MAP,HR,SpO2 of three groups were recorded.The postoperative recovery time,degree of agitation,extubation and Ramsay sedation score,VRS analgesia 24h score,postoperative adverse reaction were compared among three groups.Results There was no difference in the recovery time among the three groups(t=0.94,0.97,1.02,all P>0.05).Compared with T0,the MAP of the three groups at the time of T2 increased,but the MAP of B group and C group was significantly higher(t=4.65,5.201,all P<0.01),HR was significantly higher(t=2.382,2.915,all P<0.05).Compared with A group and B group,the agitation rate of C group was higher(u=5.54,3.47,all P<0.01).The ramsay sedation score of 1 in A group was lower than C group,the VRS score of painless rate in A,B group was higher than that of C group(all P<0.05).Postoperative 24h,there were 19,23,24 cases of the three groups with nausea and vomiting,and the incidence rates were 47.5%,57.5%,60%,respectively,the differences were not statistically significant among the three groups(all P>0.05).Conclusion General anesthesia in gynecological laparoscopic surgery using Dex combined with dezocine can make patients more stable circulation,improve patients'' recovery quatity,it is a safe and effective method for prevention of adverse reaction after general anesthesia.

Twenty-three histone methyltransferase genes were obtained from transcriptome dataset of Lonicera japonica. The nucleotide and proteins characteristics, subcellular localization, senior structural domains and conservative forecasting were analyzed. The result of phylogenetic tree showed that 23 histone methyltransferases were mainly divided into two groups: lysine methyltransferase and arginine methyltransferases. The result of gene expression showed that 23 histone methyltransferases showed preference in terms of interspecies and organs. They were more expressed in buds of L. japonica than in L. japonica var. chinensis and lower in leaves of L. japonica than in L. japonica var. chinensis. Eight genes were specific expressed in flower. These results provided basis for further understanding the function of histone methyltransferase and epigenetic regulation of active ingredients of L. japonica.

A total of 12 775 SSRs were identified from Scutellaria baicalensis Georgi genomic database, accounting for 2.56% of the total genomic sequences. The result showed that S. baicalensis SSRs were based on 68.32% dinucleotide and 18.63% trinucleotide repeats; CT/GA and TTC/GAA were predominant in the dinucleotide motifs and the trinucleotide motifs respectively. Nine primers were selected to produce highly reproducible SSR bands and were used in studying the genetic diversity of S. baicalensis, 50 individuals from ten populations. 68 SSR polymorphic loci were detected, these loci were polymorphic and displayed 4 to 12 alleles per locus with a mean number of 7; the effect number of alleles was 3. Expected heterozygosities were 0.6 and were far more greater than the average in dicotyledonous plants. PIC (polymorphism information content) was 0.72, Shannon's information index was 1.32, these all proved that S. baicalensis had a high genetic diversity in general. Genetic differentiation among population Gst was 0.131, genetic variation among population accounted for 13.1% and genetic variation within population accounted for 86.9%. The cluster analysis showed that 10 populations S. Baicalensis were classified into 2 groups, but it was not associated with geographical distribution.

Objective To explore whether brimonidine has a protective effect on retinal ganglion cells (RGCs) through improving mitochondrial function under the oxidative stress.Methods Mouse RGC-5 cells were cultured in DMEM medium containing low concentration of glucose (1 g/L),10％ fetal bovine serum and 100 U/ml penicillin-streptomycin solution.The cells were divided into normal control group,H2O2-treated group and brimonidine+ H2O2 group.H2O2 at the concentration of 800 μmol/L was added into the medium in the H2O2-treated group,and 1 μmol/L brimonidine was added into the medium for 2 hours prior to the addition of H2O2 in the brimonidine+H2O2 group.The cells were sequently cultured for 24 hours.The morphology of the cell nucleus was examined by Hoechst fluorscence staining.The expressions of apoptosis-related protein in the cells were detected by Western blot assay.Mitochondrial membrane potential was assessed by JC-1 staining.Results The cell nuclei showed round or oval in shape with consistent size in the normal control group.The pycnosis and karyorrhexis of the cell nuclei were seen in the H2O2-treated group,and less abnormal nuclei were found in the brimonidine+H2O2 group.The relative expression level of bcl-2 protein in the cells was 0.76±0.15,0.50±0.13 and 0.75±0.17 in the normal control group,H2O2-treated group and brimonidine + H2O2 group,respectively,and the expression of bcl-2 protein in the H2O2-treated group was significantly lower than that in the normal control group and brimonidine+H2O2 group (both at P＜0.05).The relative expression level of bax protein in the cells was 0.65±0.13,0.83±0.07 and 0.70±0.10 in the normal control group,H2O2-treated group and brimonidine+H2O2 group,respectively,and the expression of bax protein in the H2O2-treated group was significantly higher than that in the normal control group and brimonidine+H2O2 group (both at P＜0.05).A strong orange fluorescence was seen in the mitochondrial membrane of RGC-5 in the normal control group with a coexpression with the green fluorescence of cell membrane.In the H2O2-treated group,the orange fluorescence intensity in the cells was evidently weakened,and the number of JC-1 responsed cells was considerably increased and the orange fluorescence intensity was enhanced in the brimonidine + H2O2 group.Conclusions Brimonidine can prevent RGCs from oxidative-stress damage by improving the mitochondrial function and therefore play a potential neuroprotective effect on optic nerve.

SW872 cells were cultured in vitro with oleic acid and differentiated into mature adipocytes. The role of interleukin-6(IL-6)in the secretion of acylation-stimulating protein(ASP)in mature SW872 adipocytes was observed.The results suggested that IL-6 significantly inhibited ASP secretion into the media in a dose-and time-dependent manner in mature SW872 adipocytes.

Objective To investigate the relationship between MRI rating of white matter hyperintensities (WMH) within cholinergic pathway and vascular dementia in Binswanger's disease.Methods 41 patients with Binswanger's disease undergone inspection of MRI. On 4 selected axial images, the severity of WMH in the cholinergic pathways was rated on a 3-point scale for ten regions identified with major anatomical landmarks. The cholinergic pathways hyperintensities scale (CHIPS) were developed by Bocti based immunohistochemical tracings of the cholinergic pathways. Subjects underwent neuropsychological testing with the Mattis Dementia Rating Scale (DRS) to assess cognitive domains of interest (attention, episodic memory, executive functions). Spearman correlation coefficients were used to compute association between CHIPS score and DRS score.Results The total score of DRS, the scores of DRS attention subscale and memory subscale were 105.6±18.2, 29.5±4.2 and 11.3±3.2 respectively. The score of CHIPS was 35.6±13.7. After accounting for age and education in a multiple linear regression model, the CHIP ratings were associated with impaired performance on the DRS ( r=-0.43, P<0.05).Conclusion The MRI rating of WMH within cholinergic pathway has strong correlations with cognitive performance in patients with Binswanger's disease.

This study was aimed to evaluate the effect of triptolide (TPL) on the reversal of multidrug resistance in K562/A02 cell line. The sensitivity of K562 and K562/A02 to adriamycin (ADM) and reversal of drug resistance were determined with MTT method. The concentration of intracellular ADM and P-glycoprotein expression were detected by flow cytometry. Luciferase reporter gene assay was used to detect the transcriptional activity of MDR1 promoter. The results showed that TPL significantly decreased the resistance degree of K562/A02 cells, inhibited P-glycoprotein expression (mean fluorescent intensity decreased from 123 ± 13 to 39 ± 13) and increased the intracellular concentration of ADM (mean fluorescent intensity increased from 18 ± 5 to 34 ± 6) in K562/A02 cells. Luciferase reporter gene assay demonstrated that TPL inhibited the transcriptional activity of MDR1 promoter by 75%. It is concluded that TPL may effectively reverse the multidrug resistance in K562/A02 cells via modulating P-glycoprotein expression and increasing intracellular ADM accumulation.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition obsessing urologists and patients. It is also known as a heterogeneous syndrome, with varied etiologies, progression courses and responses to treatment. Based on the deeper insights into its pathogenesis and re-evaluation of its clinical trials, a novel phenotypic classification system UPOINT has been developed, which clinically classifies CP/CPPS patients into six domains: urinary (U), psychosocial (P), organ-specific (O), infection (I) , neurologic/systemic (N) and tenderness of pelvic floor skeletal muscles (T), and directs individualized and multimodal therapeutic approaches to CP/CPPS. This review systematically summarizes the theoretical foundation, clinical characteristics of UPOINT and treatment strategies based on the UPOINT phenotypic classification system.
