Objective To study the antiasthmatic effect of Xiaoerkechuanning Granule (KCN) in guinea pigs with allergic asthma. Method The allergic asthma model in guinea pigs was induced by ovalbumin (OVA), and detemine the incubation period of asthma, the content of malondiadehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) in blood serum, histopathologic changes of lungs. Results The KCN can markedly prolong the incubatin period, increase the activities of SOD, alleviate the histopathologic changes. Conclusion KCN has obviously protective effects on experimental allergic asthma in guinea pigs.

The extracts of marine mollusks( Abalone, Aplysia, Sepia, Arcagranosa linnaeus, Cyclina sinensis, Myti-lus coruscus, Chlamys farrei, Meretrix meretrix, Ostrea, Sinonovacula constricta and Solen gradis) classified as poly-saccharides, proteins and peptides, possess the antitumor, anti-aging, and anti-bacterial activities. Cancer patients undergoing long-term chemotherapy usually suffer from the damage to vital organs, and resistances affecting the outcomes of chemotherapy. Therefore, it is imperative to search for anti-cancer drugs with low toxicity and high efficiency. At present, several marine mollusks are being studied. Summary on the antitumor activities of the marine mollusks extrats is presented, which might provide a basis for the development of marine anti-cancer drugs.

AIM:To check the antiproliferative and apoptosis-inducing effect of Compound Changtai Granule(Radix et Rhizoma ginseng,Semen coicis,Rhizoma curcumae,etc)(CCG)on human colon carcinoma cell line(SW480).METHODS:Methy thiazolyl tetrazolium chromatomerry was used to observe the influence of several concentration of CCG on SW480 cell proliferation cultured in vitro at the various times,and flow cytometry was applied to examining the change in SW480 cell proliferation cycle and apoptosis rate.RESULTS:CCG could successfully prevent SW480 cell from entering G_0/G_1 phase and G_2/M phase,decrease cell numbers in S phase at the same time.CONCLUSION:CCG has an obvious dose-response relationship in the range of 3.51 to 7.81 mg/mL.

In this studies, an anticancer peptide was isolated from the enzymatic hydrolysate of Mytilus coruscus.CCK-8 assay was used as guide in activity screening through the isolation process of membrane filtration, DEAEsepharose chromatography, Sephadex G-25 exclusive chromatography and RP-HPLC. An anticancer peptide was obtained and identified as Asp-Leu-Tyr.

Objective:To compare the clinical value of stent assisted intestinal bypass and temporary loop ileostomy in laparoscopic low anterior resection of rectal cancer.Method:In this retrospective analysis, 57 patients undergoing laparoscopic low anterior resection for rectal cancer in the First Affiliated Hospital of Ningbo University from Jan 2020 to Jan 2022 were divided into intestinal bypass group (36 cases) and loop ileostomy group (21 cases).Result:There were no significant differences in postoperative GI function recovery and postoperative complication rate between the two groups (all P>0.05). The levels of albumin, prealbumin and hemoglobin in the intestinal bypass group were better than those in the ileostomy group when evaluated on 3rd months after operation [(40.5±2.3) g/L vs. (38.1±2.6)g/L、(26.4±2.7)mg/dl vs. (24.5±2.0)mg/dl、(137.6±5.9) g/L vs. (134.0±7.0) g/L, t=3.605、2.743、2.085, all P<0.05]. Hospital expenses of the intestinal bypass group was lower [(571 000±7 500) yuan vs. (69 300±9 100) yuan, t=-5.477, P<0.05]. Conclusion:Compared with traditional ileostomy, the stent assisted intestinal bypass reduces trauma with lower expenses and improves patients' status after laparoscopic low anterior resection for rectal cancer.
