OBJECTIVE:To compare mental state and drug safety of puerperant underwent propofol and etomidate painless abortion after regain of consciousness. METHODS:102 puerperant underwent painless abortion were selected and randomly divided into control group and trial groups with 51 cases in each group. The control group received Propofol injection 2 mg/kg intravenous-ly,and the trial group received Etomidate fat emulsion injection 0.2 mg/kg intravenously. The changes of patient’s mental state were evaluated with Positive and Negative Emotions Scale (PANAS) before anesthesia and after regain of consciousness. The changes of HR,BP,MAP and SpO2 were observed and compared between 2 groups before anesthesia and 1,2,3 and 5 min after anesthesia. The anesthetic effect and ADR were compared between 2 groups. RESULTS:Compared to before anesthesia,positive mood scores of the trial group were increased slightly after regain of consciousness,while that of the control group were increased significantly;there was statistical significance before anesthesia and after regain of consciousness (t=9.023,P<0.05);there was statistical significance between 2 groups(t=8.367,P<0.05). Negative mood scores of 2 groups were decreased significantly af-ter regain of consciousness;there was statistical significance before anesthesia and after regain of consciousness(t=8.672,9.895, P<0.05). HR,BP MAP and SpO2 of 2 groups had no statistical significance within 5 min after anesthesia(P>0.05). The total effective rate of anesthesia in control group was 80.4%,while that of trial group was 78.4%;there was no statistical signifi-cance between 2 groups (χ2=1.273,P>0.05). The incidence of nausea,vomiting,dizziness and other ADR were similar in 2 groups,but the incidence of fantasy(39.2%)in control group was significantly higher in trial group(11.8%);there was statistical significance between 2 groups(χ2=10.120,P<0.05). CONCLUSIONS:Propofol and etomidate have good stability on the respira-tory and circulatory system,anesthetic effects are correspond to the incidence of ADR. Etomidate has a better safety. But the psy-chological status of patients in the propofol group is preceding than etomidate group.

OBJECTIVE:To investigate the analgesia effect of low-dose ketamine combined with sufentanil after radical sur-gery of esophageal cancer. METHODS:Totally 153 patients of pre-implementation esophageal cancer surgery were randomly divid-ed into group A,B and C. After induction of anesthesia in patients in each group,patients in group A administered sufentanil 2 μg/kg;group B were treated with sufentanil 2.5 μg/kg;group C were treated with sufentanil 2 μg/kg + ketamine 85 μg/(kg·h). Visual analog(VAS)score and Ramsay score before and after anesthesia 4,8,16,24 and 48 h,analgesia pump pressing times and inci-dence of adverse reactions in each group were observed. RESULTS:Ramsay score in 4,8 and 16 h in each group were significant-ly higher than before anesthesia,the differences were statistically significant(P<0.05),however,compared with before,there was no significant difference in the Ramsay score in 48 h among each group(P<0.05);VAS scores in each group(except for group C in 48 h) at each time point were significantly higher than before,group C

Objective To solve the encountered problem of lack of space and dyskinesia of detector in dual energy X-ray absorptiometry system, Methods The method used PartitionMagic8.0 software to partition space in hard disk and added the load to keep the detector balance for moving, Results The original software can run in hard disk, and the pulleys are not gotten force from side. Conclusion The reason of problem is analyzed to find the method that can reduce the percentage for system failure and improve precision and accuracy of data.

Purpose:To study the expression of MT1-MMP ,EMMPRIN and P-gp in gastric carcinoma and the relation of invasion, metastasis with drug resistance in gastric carcinoma. Methods:Detected membrane-type-1 matrix metalloproteinase (MT1-MMP), extra-cellular matrix metalloproteinase inducer (EMMPRIN), P-glycoprotein (P-gp) in gastric carcinoma by immunohistochemical method. Results:Among 40 cases of gastric carcinoma, there were 15 cases (37.5%) MT1-MMP-positive, 26 cases (65%) EMMPRIN-positive, 23 cases (57.5%) P-gp-positive respectively. The over-expression of MT1-MMP, EMMPRIN, P-gp was associated with invasive depth and lymph node matasteses of tumor cells(P

This study is to investigate the effect of small interfering RNA targeting STAT3 (STAT3-siRNA) enhancing antitumor activity of doxorubicin. RT-PCR and Western blotting were used to test the expression of STAT3 mRNA and protein in the HepG2, HeLa and K562/DOX cells and the effect of STAT3-siRNA on the expression of STAT3 mRNA and protein. MTT and Trypan blue assay were performed to determine the inhibitory effect of STAT3-siRNA on HepG2, HeLa and K562/DOX cells and the effect of STAT3-siRNA enhancing antitumor activity of doxorubicin. The effects of STAT3-siRNA on intracellular accumulation of doxorubicin and cell apoptosis were performed by Arrary Scan V(TI)HCS600 High-Contents. The results showed that STAT3 gene, STAT3 and pSTAT3 protein were highly expressed in HepG2, HeLa and K562/DOX cells and STAT3-siRNA decreased the expression of STAT3 mRNA and protein. STAT3-siRNA inhibited the growth of HepG2, HeLa and K562/DOX cells. STAT3-siRNA in combination with doxorubicin decreased by 3.13, 5.22 and 1.74 fold of IC50 of HepG2, HeLa and K562/DOX cells compared with doxorubicin only. Intracellular accumulation of doxorubicin increased by 16.8%, 12.87% and 25.67% respectively in HepG2, HeLa and K562/DOX cells in the presence of STAT3-siRNA. An enhancement of doxorubicin-induced cell apoptosis was observed in HepG2, HeLa and K562/DOX cells treated with STAT3-siRNA. The results suggested that STAT3-siRNA could enhance the antitumor activity of doxorubicin on HepG2, HeLa and K562/DOX cells.

Objective To study the feasibility, safety, tolerance and the effectiveness of constraint-induced movement therapy (CIMT) in early cerebral infarction, and the long-term outcome.Methods 2 weeks after cerebral infarction, 22 patients with upper extremity weakness were divided into treatment group (11 cases, accepted CIMT) and control group (11 cases, accepted routine rehabilitation). They were assessed with Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT), Motor Activity Log (MAL) and Barthel Index (BI) before and 2 weeks, 3 months after treatment. Results The scores of FMA, WMFT, MAL and BI improved in both group (P<0.05), but more in the treatment group (P<0.05). 3 months after treatment, the score of MAL quality was no different between two group.Conclusion CIMT is safe and effective for early cerebral infarction, and more effective than routine immediately, but it is similar 3 months later.

This study is to investigate the inhibitory effect and mechanism of prosapogenin A (PSA) on MCF7. MTT assay was performed to determine the inhibitory effect of PSA on MCF7 cells. PI/Hoechst 33342 double staining was used to detect cell apoptosis. RT-PCR was used to test the mRNA levels of STAT3, GLUT1, HK and PFKL. Western blotting was performed to determine the expression of STAT3 and pSTAT3 protein in MCF7 cells. The results showed that PSA could dose-dependently inhibit cell growth of MCF7 followed by IC50 of 9.65 micrmol x L(-1) and promote cell apoptosis of MCF7. Reduced mRNA levels of STAT3, HK and PFKL were observed in MCF7 cells treated with 5 micromol x L(-1) of PSA. PSA also decreased the level of pSTAT3 protein. STAT3 siRNA caused decrease of mRNA of GLUT1, HK and PFKL which indicated STAT3 could regulate the expressions of GLUT1, HK and PFKL. The results suggested that PSA could inhibit cell growth and promote cell apoptosis of MCF7 via inhibition of STAT3 and glycometabolism-related gene.
