This paper was aimed to study the genetic diversity and genetic relationship of germplasm resource of Lonicerae Japonicae Flos in order to provide references for its breeding. A total of 36 samples from 18 farm varieties and wild species, as well as related species of Lonicera japonica Thunb. from the main production areas were studied by ISSR-PCR markers. The Jaccard coefficient was worked out by NTSYS-pc software. And a cluster dendrogram of different samples was established based on unweighted pair-group method with arithmetic mean (UPGMA). The re-sults showed that 12 ISSR primers generated 129 loci of which 114 loci were polymorphic. The average percentage of polymorphic bands (PPB) is 88.37%. In the cluster dendrogram, different samples of Lonicera japonica are in the same group, which showed that it is a natural species; the wild sample is separated from the cultivated samples; the traditional type-Maohua is relative stable, but the type of Jizhuahua includes complicated varieties, and it has obvi-ous genetic variation; the new variety Jiufeng 1 has already distinct into one stable type. It was concluded that the ISSR method was suitable for germplasm identification, genetic diversity analysis of Lonicerae Japonicae Flos, thus providing a theoretical foundation for its cultivation and breeding.

Objective To determine the optimum dose of oxycodone for anesthesia when combined with propofol in the patients undergoing induced abortion.Methods Three hundred patients, aged 18-40 yr, weighing 40-70 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , undergoing elective induced abortion, were randomly divided into 6 groups (n =50 each) using a random number table: fentanyl group (group F) and different doses of oxycodone groups (Q1-5 groups).In group F, fentanyl 1 μg/kg was intravenously injected.In Q1-5 groups, oxycodone hydrochloride 20, 40, 60, 100 and 150 μg/kg were intravenously injected, respectively.Propofol 2.5 mg/kg was intravenously injected 1 min later in all the patients, and the operation was started when the eyelash reflex disappeared.The occurrence of hypotension, bradycardia, body movement and respiratory depression during operation, and nausea and vomiting within 4 h after operation were recorded.The uterine contraction pain was assessed with numerical rating scale (NRS) at 30 min, 1 h and 4 h after operation.Patient's satisfaction was evaluated at 1 and 4 h after operation.Results With the prolongation of time, NRS score was gradually increased, and the degree of patient's satisfaction was gradually decreased in group F (P＜0.05).With the prolongation of time,NRS score was gradually decreased, and the degree of patient's satisfaction was gradually increased in Q1-2 groups (P＜0.05).There was no significant difference in NRS score and degree of patient's satisfaction between Q3-5 groups (P＞0.05).Compared with group F, NRS score was significantly decreased, and the degree of patient's satisfaction was increased at 4 h after operation in Q1-5 groups (P＜0.05).Compared with Q1-2 groups, NRS score was significantly decreased at 30 min and 4 h after operation, and the degree of patient's satisfaction was increased at 4 h after operation in Q3-5 groups (P＜0.05).Among the Q1-5 groups,the incidence of respiratory depression, body movement, and nausea and vomiting was the lowest in group Q4 (P＜0.05).Conclusion When combined with propofol, the optimum dose of oxycodone for anesthesia is 100 μg/kg in the patients undergoing induced abortion.

Objective:To silence ERCC2 (excision repair cross-complementing rodent repair deficiency,complementatin group 2,ERCC2) expression in esophageal cancer KYSE150 cells by small interfering RNA (siRNA) and observe the altered sensitivity of KYSE150 cells to paclitaxel (PTX) and elucidate the mechanism underlying the reversion of the PTX resistance of KYSE150 cells. Methods:ERCC2-targeted siRNA was synthesized in vitro and transiently transfected into ERCC2 overexpressing KYSE150 cells via Lipofectamine mediation. The mRNA and protein expression levels of ERCC2 were determined by using RT-PCR and FCM method, respectively. The sensitivity of KYSE150 cells to PTX was measured by MTT assay before and after siRNA transfection. Results:RT-PCR results suggested that the specific bands of ERCC2 mRNA were not detected in si-ERCC2 group at 24, 48 and 72 h post transfection. FCM results indicated that the expression levels of ERCC2 protein gradually decreased by 31.2%, 51.6% and 60.0% at 24, 48 and 72 h respectively(P<0.01). The IC_(50) value of PTX for ERCC2-silencing KYSE150 cells was (6.32±0.87) μg/mL, lower than that for control cells (P<0.01). Conclusion:siRNA successfully silenced the expressions of target gene ERCC2 at both the transcription and translation levels. Silencing ERCC2 expression partly reversed the resistance of KYSE150 cells to PTX.

Background and purpose: ERCC2 gene silence by siRNA interference was observed in esophageal cancer cell line and it could change cell sensitivity to taxol. This study was to investigate the biological mechanism of paclitaxel-resistance in esophageal cancer cells. Methods: ERCC2 targeting siRNA (si-ERCC2) has been synthesized. The constructor were transfected into ERCC2 cell lines high-KYSE150(bigh expression of ERCC2) through lipofectamine. RT-PCR and flow cytometry (FCM) were used to detect the ERCC2 mRNA and protein expression levels. MTr assay was used to estimate the paclitaxel sensitivity of the cells. Results: In si-ERCC2 group, ERCC2 could not be detected and ERCC2 protein expression were reduced by 31.2%, 51.6% and 60.0%, respectively, 24,48,72 b after transfection. Paclitaxel IC_(50) value for si-ERCC2 group was 6.32±0.87 μg/mL, lower than the control group(49%). Conclusion: siRNA could successfully silence the target gene ERCC2 at the level of transcription and translation of the gene, the reduction of ERCC2 expression may reverse taxol resistance of the cells.
