AIM:To establish the HPLC-fingerprint of the water-soluble constituents of Salvia miltiorrhizae Bge.on 18 batches from 9 areas in China. METHODS: Samples of Salvia miltiorrhizae Bge.from different areas were determined by Agilent 1100 DAD-HPLC on Sino Chrom ODS-BP column(250 mm?4.6 mm,5 ?m),gradient elution with methanol-water(0.7%H_3PO_4) as mobile phase,column temperature was at 30℃,flow rate was 1 mL/min,wavelength was at 280 nm,and the inject volume was 20 ?L. RESULTS: The HPLC-fingerprints of the water-soluble constituents from Salvia miltiorrhizae Bge.,including 12 mutual peaks,were developed after determination of 10 batches of drugs according to SPSS analysis.,and in which,3 characteristic components were recognized. CONCLUSION: The separation effect of peaks in fingerprints is better and the characteristic is also obvious.The RSD values of precision and reproducibility are less than 5%.This method can be used for the quality control of Salvia miltiorrhizae Bge.

Among them,compounds 4~8 were reported from this plant for the first time,compounds 2,4 and 9 showed moderate activity against selected tumor cell lines.

Objective To investigate the chemical constituents of gorgonian Muriceides collaris. Methods The compounds were isolated and purified by silica gel column,Sephadex LH-20 column chromatography and HPLC. Their chemical structures were identified by physicochemical analysis,spectroscopic analysis,and comparison with the data of literatures. Results From the CH3OH soluble extract of Muriceides collaris,nine compounds were isolated,and their structures were determined as cholesterol (1),batyl alcohol (2),benzoic acid (3),uracil (4),thymine (5),2'-deoxyuridine (6),2'-deoxythymidine (7),thymidine (8) and 2'-deoxyadenosine (9),respectively. Conclusion All compounds were obtained from the species Muriceides collaris for the first time.

Objective:To investigate the effects of preoperative administration of parecoxib sodium on stress reaction and postoperative nausea and vomiting score in patients undergoing laparoscopic cholecystectomy.Methods:A total of 112 patients undergoing laparoscopic cholecystectomy in Lishui City People's Hospital from January 2020 to January 2021 were included in this study. They were randomly divided into observation group and control group, with 56 patients per group. The observation group was intravenously administered 40 mg parecoxib sodium 30 minutes before surgery, and the control group was identically administered equal amount of 0.9% sodium chloride injection. At 1, 6, 12 and 24 hours after surgery, Visual Analogue Scale (VAS) score, cortisol and adrenocorticotropic hormone levels and postoperative nausea and vomiting score were compared between the two groups.Results:At 1, 6 and 12 hours after surgery, VAS score in the observation group was (3.23 ± 0.85) points, (2.44 ± 0.76) points, (2.37 ± 0.69) points, respectively, which were significantly lower than (4.06 ± 1.12) points, (3.24 ± 0.95) points, (3.10 ± 1.07) points in the control group ( t = 4.41, 4.92, 4.29, all P < 0.001). At 1, 6, 12 and 24 hours after surgery, cortisol level in the observation group was (287.79 ± 35.46) ng/L, (303.55 ± 34.77) ng/L, (368.58 ± 31.22) ng/L, (397.16 ± 32.60) ng/L, respectively, which were significantly lower than (337.64 ± 39.52) ng/L, (364.18 ± 36.90) ng/L, (405.56 ± 37.29) ng/L, (455.51 ± 37.81) ng/L in the control group ( t = 7.02, 8.94, 5.69, 8.74, all P < 0.05). At 1, 6, 12 and 24 hours after surgery, adrenocorticotropic hormone level in the observation group was (59.25 ± 7.63) ng/L, (65.27 ± 8.23) ng/L, (72.29 ± 7.49) ng/L, (83.63 ± 8.57) ng/L, which were significantly lower than (64.48 ± 8.06) ng/L, (71.44 ± 8.59) ng/L, (79.79 ± 8.15) ng/L, (90.08 ± 8.26) ng/L in the control group ( t = 3.52, 3.88, 5.07, 4.05, all P < 0.05). Within 24 hours after surgery, the incidence of postoperative nausea and vomiting in the observation group was significantly lower than that in the control group [12.50% (7/56) vs. 28.57% (16/56), χ2 = 4.43, P < 0.05). Within 2 hours, 2-6 hours, and > 6-24 hours, postoperative nausea and vomiting score in the observation group was (1.31 ± 0.26) points, (1.43 ± 0.32) points, and (1.46 ± 0.41) points, respectively, which was significantly lower than (1.67 ± 0.41) points, (1.83 ± 0.39) points, (1.88 ± 0.44) points in the control group ( t = 2.12, 2.37, 2.14, all P < 0.05). Conclusion:Preoperative administration of parecoxib sodium exhibits a good postoperative analgesic effect in patients undergoing laparoscopic cholecystectomy. It can effectively reduce postoperative stress reactions, decrease the incidence of postoperative nausea and vomiting, and lower the severity of postoperative nausea and vomiting, and thereby can be widely used in clinical practice.
