OBJECTIVETo explore the effectiveness and safety of transcutaneous electrical acupoint stimulation (TEAS) combined with infusion of propofol in anodynia bronchoscopy.

METHODSNinety patients who received selective bronchoscopy were randomized into a group of compound TEAS with infusion of propofol (group A), a group of compound fentanyl with propofol (group B) and a group of simple propofol (group C). In group A, the plaster electrode stimulation was applied at bilateral Hegu (LI 4), Laogong (PC 8), Neiguan (PC 6) and Waiguan (TE 5). The anesthesia was induced after 20 min of stimulation till the end of examination. In group B and group C, the electric stimulation was not adopted. In group B, before anesthesia, fentanyl 1 microg/kg was injected intravenously. Afterwards, the intravenous infusion of propofol was used in the the three groups for anesthesia. The mean arterial pressure (MAP), heart rate (HR), saturation of pulse oximetry (SpO2) and respiratory rate (RR) were recorded at different time points. The induced dosage and total dosage of propofol, examination time, the awakening time and adverse reactions were observed in the patients of each group.

RESULTSThe difference in examination time was not significant among the three groups (P > 0.05). The postoperative awakening time in group A was earlier than that in group B and group C [(220.3 +/- 110.5) s vs (285.6 +/- 109.4) s, (290.1 +/- 105.1) s, both P < 0.05]. The total dosage of propofol in group C was larger than those in group A and group B [(288.5 +/- 26.7) mg vs (225.1 +/- 30.2) mg, (230.4 +/- 29.3) mg, both P < 0.05]. The induced dosage in group C was larger than those in group A and group B [(193.7 +/- 42.3) mg vs (152.3 +/- 36.1) mg, (155.4 +/- 40.5) mg, both P < 0.05]. Every life physical sign in group A during examination was more stable as compared with that in group B and group C. The incidence of hypotension and bradycardia in group A were lower than those in group C [3.3% (1/30) vs 26.7% (8/30), 0% (0/30) vs 20.0% (6/30), both P < 0.05]. The adverse incidence of oxygen supply in group A was lower than that in group B [6.7% (2/30) vs 33.3% (10/30), P < 0.05]. Intraoperative awareness and improper memory did not happen in postoperative investigation.

CONCLUSIONIn the transcutaneous electrical acupoint stimulation combined with infusion of propofol in anodynia bronchoscopy, the physical sign of patient is stable with less adverse reactions. This method reduces anesthetic dosage and shortens the postoperative awakening time, which can be effectively applied in bronchoscopy.

Objective To evaluate the effects of an intervention programme of health education and life style modification on postmenopausal osteoporosis women. Methods A total of 120 postmenopausal osteoporosis women were enrolled in this one-year randomized controlled follow-up study and assigned to the intervention group ( Group A, n = 60) or the control group ( Group B, n = 60). Both groups were treated with alendronate sodium. In Group A, education program was performed once a season in the form of face-to-face consultation or group session. In Group B, no additional intervention was used. The primary outcome was patients' compliance in follow-up. The secondary outcomes were change in bone mineral density (BMD).BMD was measured by dual-X-ray absorptiometry (DXA) on lumbar spine and hip at baseline and 12 months after the intervention. Results After one-year intervention,51 subjects in Group A and 38 in Group B completed the follow-up. Groups A showed better compliance. BMD on lumbar spine and hip was significantly increased in both groups when compared with baseline. The changes of BMD on lumbar (0.042+0.067 vs 0.026±0.070,P=0. O29) or Words region (0.029 +0. 129 vs 0.023±0. 143,P=0. 041 ) showed statistical significance between the two groups. Conclusion For alendronate sodium treatment, health management ensures the effectiveness of the therapy and improves the compliance of the patients.

Objective To explore the proliferative and apoptotic effect of 3 different siRNAs targeting survivin in human bladder cancer cell line EJ28. Methods Three siRNAs targeting survivin and 1 fluorescence-labeled siRNA as a negative control were chemically synthesized. Transfetion efficiency was observed under fluorescence microscope after transfecting the fluorescence-labeled siRNAs. EJ28 cells were divided into 6 groups: siRNA164 group, siRNA167 group, siRNA389 group, and negative control group, lipofectin group and cell control group. The proliferation of EJ28 cell was detected by MTT assay at 24, 48 and 72 h after the transfection. Apoptotic rate was detected by Annexin V-FITC-FCM assay at 48 h.Results All the sequence-specific siRNAs targeting survivin efficiently suppressed the proliferation of EJ28 cells. siRNA 164 had the most powerful effect because of its highest inhibitory rate of (41.32?2.54)% and the highest apoptotic rate of (13.20?0.25)% at 48 h after transfection. Conclusion RNAi targeting survivin has a potential value in the gene therapy of bladder cancer.

Objective To determine the normal reference values for thromboelastography (TEG) in Chinese healthy elderly people in Beijing and compare them with those provided by the manufacturer and with people under the age of 55 years.Methods The healthy elderly people aged over 65 years were enrolled from March 2014 to April 2014.4 ml of peripheral vein blood samples were taken from each person.All subjects underwent the laboratory tests of prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time (TT) and fibrinogen (FIB).TEG parameters including reaction time (R),coagulation time (K),angle (alpha) and maximum amplitude (MA) were determined by using a Heamoscope 5000 device.Results A total of 119 healthy elderly subjects were enrolled in this study.The mean values (95％ CI) of TEG parameters for them were R:6.29 min (4.4-8.2 min),K:1.63 min (0.8-2.5 min),α-Angle:66.09° (55.0-77.1°),MA:63.43mm (54.5-72.3 mm).There were significant differences in the values of R,K and α-Angle between the elderly and non-elderly groups (P＜0.001 or 0.05).There were significant differences in the values of K,α-Angle and MA between males and females (P＜0.05 or 0.001).According to the normal reference values provided by the manufacturer,16.1％ (19/119) of the healthy elderly volunteers had at least one abnormal parameter beyond its normal range.3％ (3/119) of the healthy elderly people were diagnosed as coagulation abnormalities,yielding a specificity of 84％.Compared with normal reference values provided by the manufacturer,the value of R was lower and the value of MA was higher in the healthy elderly people in Beijing.Conclusions The normal reference values for TEG should be established based on the local population characteristics.
