OBJECTIVE:To study the distribution characteristics of germacrone from zedoary turmeric oil (ZTO) in each tis-sue of mice,and to provide reference for further application of zedoary turmeric oil. METHODS:30 KM mice were given zedoary turmeric oil 0.5 mL;6 mice were randomly selected 1,2,4,8,12 h after medication,respectively. The contents of germacrone in heart,liver,spleen,lung and kidney tissues were determined by HPLC. 15 KM mice were selected,medication and sampling method were same as above;3 mice were collected at each time point respectively. The fluorescence intensity of germacrone in above sections were observed by fluorescence. The same number of mice were selected as control in 2 trials. RESULTS:The con-centration of germacrone in each tissue 1-4 h increased gradually as time and reached the peak value at 4 h. The contents of ger-macrone in liver and spleen were significantly higher than in heart and lung. The concentrations of germacrone in each tissue were ranked as liver>spleen>kidney>heart>lung. The results of fluorescence intensity observation was same as above results. CON-CLUSIONS:Results of 2 methods show same distribution characteristics of germacrone in mice tissues,and indicate that ger-macrone is distributed more in liver,spleen and kidney tissues and less in heart and lung.

Objective This study was conducted to investigate the clinical outcomes and safety of percutaneous coronary intervention (PCI) to the single-opened vessel lesion among patients with severe left ventricular systolic dysfunction. Methods Twenty-seven patients with severe left ventricular systolic dysfunction (ejection fraction≤35%) undergoing PCI were included. All the patients received PCI only to the single-opened vessel lesion under the conditions of: (1) There were limitations to open chronic total occlusion (CTO);(2) Single-opened vessel lesion was not calcified and tortuous. Clinical outcomes, including success rate of PCI, changes of symptoms in-hospital, brain natriuretic peptide (BNP) and left ventricular ejection fraction (LVEF) pre-and one week post-PCI, the major adverse cardiac events (MACE, including death, myocardial infarction and target vessel revascularization) at 30-days after discharged were observed. Results The success rate of PCI was obtained in all 27 patients(100%), and all the patients received drug eluting stent implantation. The symptoms improvement occurred in all patients and the NYHA class improved from grade Ⅳto grade Ⅲin 22 patients(81.5%) in-hospital. Significant differences were noted in the mean BNP and LVEF between pre-PCI and one week post-PCI, BNP[(2699.6±1104.7) pg/ml vs. (737.0 ± 261.7) pg/ml, P<0.05],LVEF[(26.9±5.7)%vs. (36.0±3.41)%, P<0.05)]. No MACE happened in-hospital and at 30-days follow up. Conclusions PCI only to the single-opened vessel lesion among patients with severe left ventricular systolic dysfunction under the condition of limitations to open CTO is safe and can significantly improve clinical outcomes in-hospital and at 30-days follow up, but it must be emphasized that single-opened vessel lesion not with obvious calcification and tortuosity.

OBJECTIVE To investigate the role of gonadotropin-releasing hormone (GnRH) in es-tradiol(E2 ) induced advance of puberty onset in rats. METHODS Postnatal day 18 SD rats were given a daily intragastric administration of corn oil or E2(50 μg.kg-1 ) for consecutive 5 d. The day of vaginal opening (VO), pathological changes in ovary and protein expression levels of GnRH, G protein-coupled receptor 54 ( GPR54) and phospholipase C ( PLC) in hypothalamus were observed. RESULTS As compared to corn oil controll group, VO was advanced by about 12.2 d, corpus luteum was observed in the ovary section, and the protein expression levels of GnRH,GPR54 and PLC in hypothalamus were significantly increased by 47%, 55% and 56% in E2 group, respectively. CONCLUSION E2 induced onset of puberty advance may be closely related to regulation of the expression of GnRH, GPR54 and PLC in hypothalamus.

Objective:To compare the effects of different acupoint compatibility on the efficacy of acupuncture-drug balanced anesthesia in the patients undergoing laparoscopic cholecystectomy.Methods:A total of 140 patients of both sexes, aged 18-64 yr, with body mass index of 18.5-24.0 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, undergoing elective laparoscopic cholecystectomy under general anesthesia, were divided into 4 groups ( n=35 each) by a random number table method: general anesthesia group (group A), Hegu plus Neiguan group (group B), Hegu plus Neiguan plus Zusanli group (group C), and Hegu plus Neiguan plus Zusanli plus Sanyinjiao group (group D). Group B, group C and group D underwent percutaneous electrical stimulation of the corresponding acupoints from 30 min before induction of anesthesia to the end of operation, with a frequency of 2/100 Hz and disperse-dense waves.The intensity of stimulation was the maximum current that patients could tolerate.The intraoperative consumption of propofol and remifentanil and requirement for rescue analgesia were recorded.Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) at 24 h before surgery and 24, 48 and 72 h after surgery.The extubation time and postoperative length of hospital stay were recorded.Adverse events such as intraoperative hypertension, hypotension, bradycardia and tachycardia were recorded. Results:Compared with group A, the intraoperative consumption of propofol and remifentanil and postoperative requirement for rescue analgesia were significantly reduced, the extubation time and postoperative length of hospital stay were shortened, and PSQI was decreased at 24 and 48 h after surgery in B, C and D groups ( P<0.05). Compared with group B and group C, PSQI was significantly decreased at 24 and 48 h after surgery, and postoperative hospitalization time was shortened in group D ( P<0.05). There was no significant difference in the PSQI and incidence of intraoperative hypertension, hypotension, bradycardia and tachycardia among the four groups ( P>0.05). Conclusion:Combination of Hegu, Neiguan, Zusanli and Sanyinjiao has a better effect on the efficacy of acupuncture-drug balanced anesthesia in the patients undergoing laparoscopic cholecystectomy.

Objective:To evaluate the effect of inhaled aerosolized budesonide and salbutamol on lung function during one-lung ventilation (OLV) in rabbits.Methods:Thirty-two healthy male New Zealand white rabbits, aged 5-6 months, weighing 2.5-3.0 kg, were randomized into 4 groups ( n=8 each) using a random number table method: two-lung ventilation (TLV) group, OLV group, inhalation of aerosolized budesonide group (group B) and inhalation of aerosolized budesonide and salbutamol group (group B+ S). Bilateral lungs were ventilated for 3 h in group TLV, the left lung was ventilated for 2 h followed by 1-h TLV in OLV, B and B+ S groups, aerosolized budesonide 1 mg (diluted to 2 ml in normal saline) was inhaled before OLV in group B, and aerosolized salbutamol 0.15 mg/kg plus budesonide 0.5 mg was inhaled before OLV in group B+ S.The equal volume of aerosolized normal saline was delivered in TLV and OLV groups.Volume-controlled ventilation was used in all groups.Arterial blood samples were obtained for blood gas analysis before aerosol inhalation (T 0), 15 min and 1 h after aerosol inhalation (T 1, 2), and at the end of ventilation (T 3). Oxygenation index was calculated.Mixed venous blood samples were collected to determine the corresponding parameters.The pulmonary shunt (Qs/Qt) was calculated.Peak airway pressure (P peak), airway platform pressure (P plat), airway resistance (Raw), and lung compliance (C dyn) were continuously monitored and recorded at T 0-T 3. Results:Compared with group TLV, the concentration of lactic acid was significantly increased at T 2, 3, oxygenation index and C dyn were decreased at T 1-3, and Qs/Qt, Raw, P plat and P peak were increased in OLV, B and B+ S groups ( P<0.05). Compared with group OLV, the concentration of lactic acid was significantly decreased at T 2, 3, oxygenation index and C dyn were increased at T 1-3, and Qs/Qt, Raw, P plat and P peak were decreased in B and B+ S groups ( P<0.05). Compared with group BD, the C dyn was significantly increased at T 1-3, and Qs/Qt, Raw and P peak were decreased in group B+ S ( P<0.05). Conclusion:Inhaled aerosolized budesonide and salbutamol can effectively improve lung function during OLV in rabbits.
