ABSTRACT
OBJECTIVE To provide reference for quality control of Gentiana rhodantha. METHODS Taking 52 batches of G. rhodantha as subject， ultra-high performance liquid chromatography （UPLC） fingerprint was adopted. The similarity of 52 batches of medicinal materials samples was evaluated by the Similarity Evaluation System for Chromatographic Fingerprints of Traditional Chinese Medicine （2004A edition）； the content of mangiferin was determined； chemometric analyses [cluster analysis， principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA）] were performed. RESULTS UPLC fingerprints of 52 batches of G. rhodantha were established， 17 common peaks were identified， and 6 of them were identified， which were loganic acid （peak 1）， neomangiferin （peak 3）， swertiamarin （peak 5）， dangyin （peak 6）， mangiferin （peak 7） and isoorientin （peak 9）. The similarities of 52 batches of medicinal materials samples were all greater than 0.9； cluster analysis showed that S1-S46， S48-S52 clustered into one class， and S47 alone； PCA results showed that the cumulative variance contribution rate of the first six principal components was 82.928%； OPLS-DA results showed that the corresponding components of swertiamarin， mangiferin and chemical composition represented by peak 4， 14， 15， 16 were the main iconic components affecting the quality differences of G. rhodantha medicinal materials. The contents of mangiferin in 52 batches of medicinal material samples ranged from 18.2 to 101.0 mg/g， mostly in accordance with 2020 edition of Chinese Pharmacopoeia. CONCLUSIONS The established UPLC fingerprint and chemometric analysis methods combined with content determination method of mangiferin can comprehensively evaluate the quality of G. rhodantha.
ABSTRACT
Objective@#To discuss the influence of temperature-holding nursing in the anesthesia and stress state during the recovery period of general anesthesia for patients with thoracoscopic lung surgery.@*Methods@#120 patients with thoracoscopic lung surgery underwent the general anesthesia from January 2017 to July 2018 in our hospital were selected and randomly assigned to two groups, 60 cases in each group. At the recovery period, the control group was treated with conventional nursing; the observation group was treated with conventional nursing and temperature-holding nursing. At each time period, the body temperature, stress response and postoperative rehabilitation conditions were probed.@*Results@#At the end of the operation 30 minutes, 60 minutes and the end of the operation, the body temperature of the observation group was (36.39±0.34)°C, (36.50±0.38)°C, (36.56±0.38)°C, and the control group was (35.49±0.31)°C, (35.63±0.41) °C, (36.17±0.52)°C, the difference between the two groups was statistically significant (t=15.15, 12.01, 4.69, P<0.05). NE was (279.3±87.4)ng/L, (321.5±110.6)ng/L, (363.5±108.2) ng/L at 30 min, 60 min, and end of surgery. E was (342.5±81.6)ng/L, (320.2±59.4)ng/L, (169.4±54.2)ng/L at 30 min, 60 min, and end of surgery. NE in the control group were (244.8±87.5)ng/L, (390.8±98.6)ng/L, (469.7±97.7)ng/L, and E was (129.5±39.6)ng/, (187.0±51.3) ng/L, (327.6 ±68.9) ng/L, and he difference between the two groups was statistically significant (t=2.161~13.979, P <0.05).The operation time, the postoperative retention time of PACU, the complete recovery of consciousness and the time of removal of tracheal catheter in the observation group were (65.93±21.94) min, (32.85±3.22) min, (18.60±5.26) min, (24.19±6.73) min, respectively. The groups were (87.52±18.42) min, (50.06±4.27) min, (26.54±4.81) min, (32.40±8.05) min, and the difference between the two groups was statistically significant (t=5.838~24.927, P<0.05).@*Conclusion@#The temperature-holding nursing can improve the recovery conditions and reduce the stress response for patients with thoracoscopic lung surgery. It is worthy of clinical promotion.
