Objective To investigate the hydrophilic chemical constituents from Thesium Chinensis Turcz.Methods The water extract of Thesium Chinensis Turcz.was adsorbed onto AB-8 resin column and eluted with 50% ethanol to give the hydrophilic portion TT50.TT50 was further separated and purified by repeated column chromatography on silica gel,Sephadex LH-20.The structures of these purified compounds were identified by NMR spectral analysis and comparison with the reported data.Results Six compounds were isolated and identified as kaempferol(1),kaempferol-3-O-glucoside(2),kaepmferol-3,7-di-O-β-D-glucopyranoside(3),kaempferol-3-O-L-rhamnopyranosyl(1 → 2)-β-D-glucopyranoside(4),kaemperol-3-O-α-L-rham-nopyranosyl(1→2)-[6-O-acetyl]-β-D-glucopyranoside(5),rutinoside(6).Conclusion The main constituents of TT50 were kaempferol glycosides.Compounds 4 and 5 were isolated from this plant for the first time.

Objective To evaluate the therapeutic effects of Thesium chinensis Turcz extracts on IgA nephropathy (IgAN) rats .Methods The hot water extracted solution of Thesium chinensis Turcz flow through the AB‐8 macroreticular res‐in column repeatedly ,then being eluted with different contents of ethanol to get four part of extract .The IgAN model of SD rats were established by oral intake of bovine serum albumin(BSA ,400 mg/kg) together with injection of lipopolysaccharide(LPS) and CCl4 .Beginning with 8th week ,the positive group(LGT ,10 mg/kg) ,water extract group(TT ,1 .0 g/kg) ,water soluble group(TTW ,0 .4 g/kg) ,high polarity group(TT20 ,0 .4 g/kg) and medium polarity group(TT50 ,0 .4 g/kg) rats were intragas‐tric administrated drug daily ,the normal group control and model control group rats were given with saline(n=8) .During the next 5 weeks treatment process ,the 24 h urine volume ,24 h urine protein concentration ,and quantity of erythrocyte in urine were observed .The levels of TP ,ALP ,ALT ,AST ,Scr and BUN in serum were determined .The expression of IgA deposition was measured by immunofluorescence staining ,and the pathological changes of kidney tissue were assayed after the therapy process .Results After 5 weeks therapy ,the 24 h urine protein concentration ,the quantity of erythrocyte in urine ,and the level of Scr and BUN of TT and TT50 groups were significantly lower than model control .The fluorescence intensities in the me‐sangial area were weaker than model control .Also ,the degrees of renal capsule expansion and mesangial matrix proliferations , and the kidney tubules damage of TT and TT50 groups were weaker than those of model control .Conclusion The water extract and its medium polarity fraction of Thesium chinensis Turcz show good therapeutic effects on IgAN rats .

Objective:To explore the effect of laparoscopic surgery on postoperative rehabilitation and stress response of patients with colorectal cancer.Methods:From January 2018 to September 2019, 94 patients with colorectal cancer were selected in the General Hospital of Marine Police of the Chinese People's Armed Police Force.They were divided into observation group (47 cases) and control group (47 cases) according to the random digital table method.The observation group was treated with laparoscopic surgery, while the control group was treated with open surgery.The changes of perioperative indicators, postoperative rehabilitation indicators, postoperative complications and 24-hour stress response indicators were compared between the two groups.Results:The time of lymph node dissection and operation had no statistically significant differences between the two groups (all P>0.05). The amount of bleeding of the observation group [(153.61±27.58)mL] was less than that of the control group [(271.32±23.25)mL] ( t=22.371, P<0.05). In the observation group, the exhaust time [(43.27±6.18)h] and the recovery time of bowel sounds [(20.31±3.28)h] were faster than those in the control group [(67.38±9.91)h and (34.54±5.17)h] ( t=14.153, 15.934, all P<0.05). The incidence of postoperative complications in the observation group (4.26%) was lower than that in the control group (21.28%) (χ 2=6.114, P<0.05). The serum levels of norepinephrine (NE) [(92.13±10.45)μg/L], C-reactive protein (CRP) [(17.38±3.01)mg/L] and Cor [(137.87±23.15)μg/L] in the observation group were lower than those in the control group [(136.27±15.42)μg/L, (26.73±2.34)mg/L and (185.42±27.39)μg/L] ( t=16.245, 16.813, 9.090, all P<0.05). Conclusion:Laparoscopic radical resection of colorectal cancer has good effect on patients with colorectal cancer.It can speed up postoperative rehabilitation and reduce stress response.It is worthy of popularizing.
