Objective To investigate the pharmacologic action of the Magnolia biondii Pamp volatile oil nanometer bangosome. MethodsThe pharmacologic action of the Magnolia biondii Pamp volatile oil nanometer bangosome was evaluated by observing its effect on Jimpy mice with swelling ear,capillary permeability and rats with allergic symptoms. Results The Magnolia biondii Pamp volatile oil nanometer bangosome could significantly relieve the degree of swelling in Jimpy mice extended by p-xylene,inhibit the increased capillary permeability in Jimpy mice extended by HAC,and combat the symptoms of rhinocnesmus,sneezing,nasal discharge with a better effect than the Magnolia biondii Pamp volatile oil. Conclusion The Magnolia biondii Pamp Volatile oil nanometer bangosome has a good anti-inflammation and anti-hypersensitiveness effect,which upgrades the effect of the Magnolia biondii Pamp volatile oil.

The occurrence and development of solid tumor is a multi-factor,multi-step and multi-gene interactive process.The generation of micro vasculature of solid tumor,as well as the interaction between tumor and micro-environment,decides the tumor's biological characteristics of growth,recurrence,invasion and metastasis.Reasonable application of anti-angiogenesis therapy enables the normalization of tumor vascular system to enhance the efficiency of chemotherapy and radiation treatment and prolong survival time in patients.

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 study the effect of varicocele(VC) on the expressions of hypoxia-inducible factor-1?(HIF-1?) and apoptosis-associated gene Bax in germ cells of adolescent rats,and investigate the mechanism of the infertility resulting from varicocele. Methods The varicocele model was established by partial ligation of the left renal vein in adolescent male Wistar rats. A total of 25 rats were randomly divided into 2 groups,namely varicocele group(n=15) and sham operation group (SOG,n=10). All the animals were killed 30 d after operation. The left testis was collected and the expression of HIF-1? and Bax was detected by immunohistochemical method. Results The expression of HIF-1? and Bax in left testis of varicocele group was significantly higher than that of sham operation group(P

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: Changes in the ?2 integrin of adhesion molecules between cells are closely associated with the invasion and migration of tumor cells.This study aimed at the effect of anti-?2 integrin on the invasion and migration of osteosarcoma MG63 cells. Methods: The osteosarcoma MG63 cell line was cultured in the DMEM medium.The effect of the anti-?2 integrin monoclonal antibody on the migration and invasion of tumor cells were measured by scratch assay and Transwell assay.The migration and invasion cells were stained by Crystal violet staining and counted under the hundredfold microscope.Results: Compared with the control group,the migration and invasion abilities of the MG63 cells were significantly decreased in the anti-?2 treatment groups.Conclusion: Anti-?2 integrin may inhibit the migration and invasion of osteosarcoma cells.

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.
