Objective To select the components for quality control of Fructus Lycii based on the absorption of its extract. Methods To investigate metabolism of components of Fructus Lycii, everted rat gut sacs was carried out as well as the blood was taken from abdominal aorta,.and all samples were analysised by HPLC. Results There are twelve constituents absorbed between ileum and jejunum of rat , and four constituents were detected in the blood. Compound 2, 3, 4, 5, 6, 9, 10, 11 were absorbed in prototype forms in the intestine directly,and compound 1, 7, 8, 12 were new ones. On the other hand, four compositions(3, 7, 10, 13)could be absorbed into blood through analysis serum samples obtaining from aorta abdominalis of rats. Two of them (3, 10)could be absorbed directly by intestine, while(7)was absorbed into blood in new form . Conclusion Based on the intestinal absorption experiment and analysion of compsition in blood, components (3, 10, 13) can be the quality control ingredients of Fructus Lycii.

BACKGROUND:Evaluation of vertical jumping ability is usual y only limited to height measurements. The measurements of parameters that describe kinetic factors may provide a better assessment of a patient’s jumping ability.
OBJECTIVE:To determine the deficit in one-legged vertical jumping ability and to clarify the relationships between the maximum jumping height and the maximum power, force and velocity during one-legged vertical jumps after anterior cruciate ligament reconstruction.
METHODS:Twenty-five healthy subjects (10 males and 15 females) and 25 anterior cruciate ligament reconstructed patients (10 males and 15 females) participated in this study. The isokinetic quadriceps femoris strength and one-legged vertical jumping ability were evaluated by the height, power, force and velocity in al subjects.
RESULTS AND CONCLUSION:(1) The maximum height of the one-legged vertical jumps was only significantly correlated with the maximum force in the healthy subjects (P<0.05). (2) However, for the reconstructed and unreconstructed legs in anterior cruciate ligament reconstructed patients, the maximum jumping height was significantly correlated with the maximum power, force and velocity during one-legged vertical jumps (P<0.05). (3) These findings suggest the importance of a knee strategy during one-legged vertical jumps for rehabilitation after anterior cruciate ligament reconstruction. Assessment of the jumping ability after anterior cruciate ligament reconstruction may be determined by the maximum power instead of the maximum jumping height.

This study was aimed to determine the solubility an d oil-water partition coefficient of main active com-ponents in Ge-Gen Qin-Lian (GGQL) Tablets (puerarin, baicalin and berberine hydrochloride) in phosphate buffer solution of different pH values and under the background of many components. Solubility of puerarin, baicalin and berberine hydrochloride in different medium pH, and oil-water partition coefficient of the octanol-water and oc-tanol-buffer system were determined by HPLC method. The results showed that the solubility and oil-water partition coefficient of puerarin, baicalin and berberine hydrochloride were varied with the change of pH, and varied under the background of components. At pH 7.4, the solubility was the biggest;puerarin was 7.56 mg·mL-1;baicalin was 17.07 mg·mL-1; berberine hydrochloride was 3.57 mg·mL-1. Oil-water partition coefficient P of these components at pH 1.0 was bigger;puerarin was 0.420 (lgP=-0.38);baicalin was 10.783 (lgP=1.03);berberine hydrochloride was 0.267 (lgP=-0.57). It was concluded that lipid solubility of puerarin, baicalin and berberine hydrochloride at pH 1.0 was better. It was speculated that better absorption in the stomach, and low lipid solubility under other pH. It was speculated that lipid solubility may be one of the reasons affecting the intestinal absorption.

Objective:To explore the effects of different anesthesia methods on anesthesia quality, postoperative recovery, cognitive status and pain in patients undergoing laparoscopic hysterectomy.Methods:A prospective study was conducted among 98 patients who underwent laparoscopic hysterectomy in Donghai County People′s Hospital of Jiangsu Province from July 2020 to December 2022. According to different anesthesia methods, the subjects were divided into group A (48 cases, intravenous-inhalation combined anesthesia) and group B (50 cases, intravenous general anesthesia and epidural anesthesia). The recovery quality, cognitive status and VAS scores before operation (T 0), at 12 h after operation (T 1), 24 h after operation (T 2) and 48 h after operation (T 3) were compared between the groups. The total incidence rates of adverse reactions in the two groups were recorded. Results:The extubation time, respiratory recovery time and awakening time in group B were shorter than those in group A: (5.69 ± 0.75) min vs. (10.02 ± 1.26) min, (4.52 ± 0.65) min vs. (6.59 ± 1.04) min, (8.65 ± 1.12) min vs. (13.52 ± 1.45) min ( P<0.05). The two groups had similar mini-mental state examination (MMSE) scores and VAS scores at T 0 ( P>0.05). MMSE scores of the two groups were lower at T 1-T 3 than T 0. Group B had higher scores than group A at T 1-T 3: (23.14 ± 1.85) scores vs. (20.36 ± 2.15) scores, (25.18 ± 2.47) scores vs. (22.31 ± 2.35) scores, (27.05 ± 1.18) scores vs. (26.31 ± 1.01) scores, P<0.05. VAS scores of the two groups were higher at T 1-T 3 than T 0. Group B had lower scores than group A: (5.17 ± 0.54) scores vs. (6.21 ± 0.75) scores, (4.42 ± 0.51) scores vs. (5.63 ± 0.62) scores, (2.58 ± 0.34) scores vs. (3.14 ± 0.42) scores, P<0.05. The total incidence rates of adverse reactions in the two groups had no statistical difference ( χ2 = 0.17, P>0.05). Conclusions:Compared with intravenous-inhalation combined anesthesia, general anesthesia combined with epidural anesthesia has better anesthesia quality in patients undergoing laparoscopic hysterectomy, which can improve postoperative cognitive function and relieve pain. The two anesthesia methods are both safe.

ObjectiveBased on sequential metabolism and ultra-high performance liquid chromatography-high resolution mass spectrometry （UPLC-HRMS）， to identify the prototype components and metabolites of Tongfengding capsules in rat plasma. MethodAn ACQUITY UPLC BEH Shield RP18 column （2.1 mm×100 mm， 1.7 µm） was used for gradient elution with 0.1% formic acid aqueous solution （A）-acetonitrile （B） as the mobile phase （0-1 min， 5%B； 1-2.4 min， 5%-10%B； 2.4-13.5 min， 10%-32%B； 13.5-18.5 min， 32%-90%B； 18.5-19 min， 90%-5%B； 19-21 min， 5%B） at a flow rate of 0.3 mL·min^-1， injection volume of 2 μL and column temperature at 35 ℃. The heated electrospray ionization （HESI） was applied under positive and negative ion modes， and the scanning range was m/z 100-1 500. By comparing the differences between the administered plasma and the blank plasma， the prototype components and metabolites in intestinal metabolism sample and liver metabolism sample prepared by intestinal perfusion with parallel blood collection， and comprehensive metabolism sample prepared by intragastric administration method were identified. ResultA total of 76， 53， 74 chemical components were detected in the intestinal metabolism sample， the liver metabolism sample and the comprehensive metabolism sample. A total of 100 components were identified from these different plasma samples， including 64 prototype components （34 alkaloids， 12 terpenoids， 9 organic acids， 6 flavonoids and 3 other components） and 36 metabolites. The main metabolic reactions involved in the formation of metabolites were glucuronidation， deglucosylation， dehydrogenation and hydroxylation. ConclusionThe chemical components of Tongfengding capsules can undergo a series of metabolic reactions in the intestine and liver， and a large number of metabolites are generated， among which alkaloids may be the leading component group for efficacy， which can lay the foundation for systematic elucidating the material basis of Tongfengding capsules in vivo.
