Objective To reinvestigate the high performance thin-layer chromatography(HPTLC)method for solving the problem of difficulty in separating between ginsenoside-Re and notoginsenoside-R1,and to establish a specific,fast and economic routine identification and quality assessment method for Notoginseng(San Qi).Methods Chromatographic conditions were as follows:stationary phase-precoated HPTLC silica gel 60 plate(20? 10 cm,Merck);developing solvent system:CH2Cl2-absolute ethanol-water(70 ∶ 45 ∶ 6.5);relative humidity:lower than 18 % ;temperature:10～ 25 ℃ ;derivative reagent:10 % H2SO4 ethanolic solution,heating at 105 ℃ for 3 min and observing the fluorescent chromatogram in a UV cabinet at 366 nm.Results The HPTLC fingerprint consisted of 10 fluorescent bands(peaks in the profile)including ginsenoside-Rb1,Rd,Re,Rg1 and notoginsenoside-R1,which presented the relative consistent ratio of the main peaks generated from the image of the chemical components distribution pattern through scanning by TLC scanner or computer-aided similarity evaluation(CASE)software.Conclusion Notoginsenoside-R1,the specific component of San Qi,is spotlighted in the HPTLC image and separated from ginenoside-Re,which indicates HPTLC method being simple,fast,and effective.The HPTLC fingerprints of 24 batches of samples from different locations(Wenshan of Yunnan,Xinyi of Guangdong)and markets,with different grades show the high chemical stabilities of this Dammarane-type saponins distribution.

The rat c-erbA? cDNA fragment was used as probe to investigate the expression of T3 receptor gene in brain, heart and kidney in hyperthyroid and hypothyroid rats. There were three types of c-erbA? mRNA-6. 0kb, -5. 0kb and -2. 0kb in all examined tissues. In heart and kidney, the levels of c-erbA? mRNA decreased in hyperthyroid rats and increased in hypothyroid rats. It might be a compensatory mechanism. In brain, however, the level of c-erbA? mRNA was unaffected by thyroid status. The results suggest that the T3 receptor gene may have an auto-regulatory mechanism in rat heart and kidney under different thyroid status.

Objective To investigate the effects of intravenous penehyclidine hydrochloride or doxofylline on respiratory mechanics during non-thoracotomy in patients with chronic obstructive pulmonary disease (COPD).Methods One hundred and thirty-five ASA Ⅱ or Ⅲ patients with COPD, aged 55-86 yr, weighing 44-78 kg,scheduled for elective non-thoracotomy under general anesthesia, were randomly divided into 3 groups ( n = 45 each): control group (group C), penehyclidine hydrochloride group (group P) and doxofylline group (group D).Anesthesia was induced with fentanyl 4 μg/kg, propofol 1.5 rg/kg and cis-atracurium 0.2 mg/kg. The patients were tracheal intubated and mechanically ventilated. PETCO2 was maintained at 40 mm Hg. At 5 rin after tracheal intubation, penehyclidine hydrochloride 0.01 mg/kg was injected intravenously in group P, and doxofylline 4 mg/kg was injected intravenously in group D. The equal volume of normal saline was injected intravenously in group C. Anesthesia was maintained with propofol 5 mg· kg- 1 · h- 1, eis-atracurium 0.2 mg· kg- 1 · h- 1, and intermittent iv boluses of fentsnyl. The auditory evoked potential index was maintained at 15-20 during operation. The peak airway pressure, airway plateau pressure, lung compliance and airway resistance were recorded immediately before administration, and at 30, 45 and 60 rin after administration. Results Compared with group C, the peak airway pressure, airway plateau pressure and airway resistance were significantly decreased, while the lung compliance was significantly increased at each time point after administration in groups P and D ( P ＜ 0.05 ). There was no significant difference in the parameters of respiratory mechanics at each time point between group P and group D ( P ＞ 0.05). Conclusion Both intravenous penehyclidine hydrochloride and doxofylline can improve respiratory mechanics during non-thoracotomy in patients with COPD.

Objective This study aimed to discuss the different assessment of pain among medical and nursing staff and cancer patients and supply reference for proper analgesic precept for clinical application and nursing measures. Methods We collected the assessment of psychological pain and physiological pain by 55 hospitalization cancer patients, 40 physicians in-charge and 55 nurses in-charge in one week by Johnson inventory. The assessment results were compared and at the same time the relevant problems of the attitude to cancer pain by patients was also investigated. Results Improper recognition existed in cancer pain treatment by most cancer patients. The physiological pain was higher than the psychological pain assessed by both patients and nurses (P<0.05). But the pain assessment by patients was higher than that by the nurses (P<0.05). The assessment of psychological pain was higher than the physiological pain by doctors and both aspects were lower than those by patients, but no statistical difference was seen (P>0.05). The assessment by doctors was more accurate than that by nurses. Conclusions Routine establishment of pain assessment inventory for patients could instruct patients how to record the degree of their pain. We should strengthen the standard training about pain management knowledge and give timely communication with patients' cancer pain.
