BACKGROUND:18-Alkylated-chitosan has been proved to exhibit a good coagulation capacity through hydrophobic modification. OBJECTIVE:To improve the adhesion between the material and the wound through the introduction of alkylated-chitosan molecules. METHODS:The alkyl group was introduced in the chitosan by potentiodynamic method to prepare the alkylated-chitosan with different substitution degrees (7%,16%, 26%and 40%), and then their structure, viscosity, porosity, water absorption, contact angle and in vitro coagulation capacity were detected. Thirty New Zealand rabbits were enrol ed, modeled into the left femoral artery hemorrhage, and randomized into six groups, including four experimental groups, positive control and control groups, fol owed by treated with alkylated-chitosan sponges with different degrees of substitution, absorbable hemostatic gauze and chitosan sponge, respectively. Afterwards, the blood loss and clotting time were observed. RESULTS AND CONCLUISON:With the degree of substitution increased, the viscosity of alkylated-chitosan increased firstly and then decreased, the porosity and water absorption decreased gradual y, and the contact angle on a rise. Compared with chitosan, different alkylated-chitosans showed a better henostatic effect in vitro, especial y the alkylated-chitosan with 16%substitution degree. The blood loss and clotting time in the experimental groups except that the alkylated-chitosan with 7%substitution degree were significantly lower than those in the control group (P<0.05);the bold loss in the alkylated-chitosan with 40%substitution degree group was significantly lower than that in the positive control group (P<0.05). These findings suggest that the alkylated-chitosan with 40%substitution degree exhibits the best hemostatic effect in vivo.

Objective To evaluate the value of monitoring circular blood interleukin(IL)-17 for predicting 60 d mortality rate in premature infants with necrotizing enterocolitis(NEC).Methods A total of 85 neonates with surgically or medically treated NEC were retrospectively included.Serum IL-17 level was detected in diagnosing NEC and before preparing operation for evaluating its predictive value.Results The mortality rate after 60 d was 20 ％ (17/85),in which 5 (10 ％)was in the medical treatment group and 12(34％) in the surgical treatment group.The IL-17 level was significantly correlated with mortality rate after 30 d [odds ratio (OR):1.38;CI:1.14-1.67;P=0.001].The preoperative IL-17 level in the surgical treatment group was 27-7 500 pg/mL(median 2 625 pg/mL),which was significantly higher than mean 156 pg/mL in the medical treatment group.The difference in the area under curve(AUC)between the medical treatment group and surgical treatment group was 0.82(CI:0.74-0.90).The critical value of IL-17 for detection significance was 1 783 pg/mL(sensitivity was 90.5％,specificity was 59.2％).Conclusion Serum IL-17 level is correlated with the mortality rate after 60 d.

Our earlier research has shown that mono-substituted N-phenyl-2, 2-dichloroacetamide exhibited much higher anti-cancer activity than the lead compound sodium dichloroacetate (DCA). In this paper, a variety of multi-substituted N-phenyl-2, 2-dichloroacetamides were synthesized and biologically evaluated. The results showed that 3, 5-disubstituted N-phenyl-2, 2-dichloroacetamide analogues had satisfactory potency. Among them, N-(3, 5-diiodophenyl)-2, 2-dichloroacetamide had an IC50 of 2.84 micromol x L(-1) against non-small cell lung cancer cell line A549 and could induce cancer cell apoptosis.

Objective: To observe the therapeutic effect of acupuncture therapy for treatment of chronic atrophic gastritis. Methods: According to the theory of TCM, 36 cases of chronic atrophic gastritis were differentiated and treated by acupuncture. Gastroscopy and electrogastrograph (EGG) of the body surface, gastric acid and pepsin, blood gastrin, blood prostaglandin E (PGE), gastric mucosal cells and G cells are recorded. Results: Acupuncture therapy had a better effect in improving clinical symptoms, the markedly effective rate was 97.2% and the disappearing rate of clinical manifestations 97.02%;after acupuncture treatment,blood PGE concentration increased; gastric acid secretion increased; gastric dynamics was enhanced and the amplitude of EGG rose; acupuncture could significantly facilitate secretion of gastrin. Conclusion: Acupuncture is a convenient treatment method for atrophic gastritis with quick effect and without side effects.

Objective:To propose a strategy for detecting early gastric cancer (EGC) under high-definition gastroscopy.Methods:Data of 469 lesions of EGC or high grade intraepithelial neoplasia (HGIN) confirmed by pathology detected at The Seventh Medical Center of Chinese People′s Liberation Army General Hospital from January 2013 to January 2020 were collected and gastroscopic images were re-interpreted. The Helicobacter pylori ( HP) infection status, lesion location in the area of atrophy or at the cardia, morphological type of lesions, lesions with/without clear or regular boundary, and lesion color were analyzed for morphological characteristics of EGC and HGIN under high-definition gastroscopy. Results:Among the 469 lesions of EGC or HGIN, HP-negative lesions accounted for 2.1% (10/469) and ulcerative lesions for 7.7% (36/469). Among non-ulcerative lesions of suspected HP infection ( n=423), there were 28 lesions in the cardia outside the atrophic area and 82.1% (23/28) were reddish under white light imaging. There were 29 non-cardiac lesions outside the atrophic area and 82.8% (24/29) were white or showed clear border under white light imaging. Inside the atrophic area, there were 73 elevated lesions, 95.9% (70/73) of which had clear border or irregular depression on the top. There were 293 flat/depressed lesions in the atrophic area, and 90.8% (266/293) had irregular border or were brown under narrow band imaging. Conclusion:According to the status of HP infection, the location and morphological category of lesions, above endoscopic features can be used as clues to detect EGC and HGIN.
