Objective To obtain highly purified oligodendrocyte precursor lineage cells in vitro and make identification.Methods The oligodendrocyte precursors were separated from astrocyte by orbital shaker and further purified by differential adhesion,and finally cultured in chemically defined serum-free medium,with appended neurotrophin 2(N2),platelet-derived growth factor(PDGF),basic fibroblast growth factor(bFGF).Immunofluorescence assay was applied to identify the separated cells with A2B5,O4,O1 and glial fibrillary acidic protein(GFAP) antibodies.Results Over 95% of cultured oligodendrocyte precursor cells were obtained.The oligodendrocyte progenitors were A2B5 and O4 positive,immature oligodendrocytes were O4 and O1 positive while GFAP were negative.Conclusions Separation and purification by shaking and differential adhesion and chemically defined medium are suitable and effective to obtain highly purified oligodendrocyte precursor cells.Cell output will increase notabily and rest in immature phase by appending both N2,PDGF and bFGF.

Objective To study the therapeutic value of endoscopy for secondary prophylaxis of esophagogastricvariceal bleeding(EGVB).Methods Records of 117 patients with EGVB who were treated with endoscopic ligation and/or histoacryl injection (n =55) and devascularization (n =62) from August 2006 to September 2014 were reviewed.Rebleeding rate,time of rebleeding,incidence of complication,cumulative survival rate,length of ward stay and mean total costs were compared between two groups.Indices were compared according to Child-Pugh.Results The rebleeding rate in the endoscopic group was higher than that in the surgical group[46.2％(24/52) VS 25.0％(15/60),P=0.019] during a mean follow-up of 32.5 months,especially in Child-Pugh B[60.0％(15/25) VS 22.2％(6/27),P=0.006].But the rebleeding time was similar between two groups(P＞0.05).The rate of complications in endoscopic group was lower than that in surgical group [20.0％ (11/55) VS 32.3％ (20/62),P =0.134].No significant difference in cumulative survival rate was observed between the groups (89.1％ VS 87.1％,P＞0.05).The length of ward stay[(14±9)d VS(23±8) d,P＜0.001] and mean total cost[(54 136.79± 44 836.32) yuan VS (73 601.86± 103 403.74)yuan,P＜0.05] in endoscopic group were significantly less than those in surgical group.Conclusion Therapeutic endoscopy is as effective as secondary prophylaxis of esophagogastric variceal bleeding.Endoscopic treatment leads to higher rebleeding rate,but is advantageous in similar rebleeding time,smaller injury,less complications,shorter length of ward stay and lower costs.

OBJECTIVETo investigate the protect effects of sodium ferulate (SF) on the daunormbicin(DNR-induced cardiotoxicity in juvenile rats.

METHODSForty male juvenile SD rats were randomly divided into control group (Control), daunorubicin group (DNR), sodium ferudate treatment group (DNR + SF), sodium ferudate group (SF) (n = 10) . Juvenile rats were intraperitoneally treated with DNR (2.5 mg/kg every week for a cumulative dose of 10 mg/kg) preparation immature myocardial injury model in presence with SF (60 mg/kg) oral treat- ment for 25 days. The left ventricular pressure and its response to isoproterenol were measured using left ventricular catheter. Rat myocardium myocardial pathology specimens and ultrastructure changes were also observed. The expression of cardiac Troponin I (cTNI) was detected by Western blot and RT-PCR. Results: SF treatment could inhibit the decreasing of heart rates induced by DNR damage (P < 0.05); it could increase the left ventrivular end diastolic pressure(LVEDP), heart rate, the maximal left ventrivular systolic speed(LVP + dp/dtmax) and the maximal left ventrivular diastolic speed (LVP-dp/dtmax) responding to isoproterenol stimulation(P < 0.01); SF also could improve the myocardial ultrastructure injuries and inhibit the decreasing of cTNI expression caused by DNR damages (P < 0.05).

CONCLUSIONSF treatment could alleviate the decreasing of cardiac reservation induced by DNR damages in juvenile rats, which might be related to its reversing the effects on the cardiac systolic and diastolic function injuries and its inhibiting effects on the decreasing of cTNI expression caused by DNR. The mechanism of SF preventing daunorubicin-induced cardiotoxicity in juvenile rats is relevant to inhabited cardiac Troponin I expression.

Objective: To investigate the prevalence and influencing factors of adolescent depression symptoms in Zhejiang, so as to provide reference for improving their mental health. Methods: The middle school and university students in 11 cities of Zhejiang Province were selected by stratified cluster random sampling method. The depression symptoms of the adolescents were assessed by Center for Epidemiological Survey-Depression Scale ( CES-D ) and the influencing factors were analyzed by multivariate logistic regression model. Results: A total of 25 855 students were investigated, and 25 614 ( 99.07% ) valid questionnaires were collected. The detection rate of depressive symptoms was 26.86%(6 879 cases). The detection rate of depressive symptoms in girls was 29.75%, which was higher than 24.12% in boys ( P<0.05). The detection rate of depressive symptoms in high school students was 31.74%, the highest compared with other grades. The multivariate regression analysis showed that female students ( OR=1.690, 95%CI: 1.592-1.794 ), resident students ( OR=1.071, 95%CI: 1.010-1.137 ) , internet addiction ( OR=2.948, 95%CI: 2.527-3.439 ) , attempt smoking ( OR=1.516, 95%CI: 1.359-1.690 ), drinking ( OR=1.624, 95%CI: 1.525-1.729 ), bullied in the past 30 days ( OR=3.143, 95%CI: 2.938-3.363 and having serious injuries within a year ( OR=1.369, 95%CI: 1.263-1.543 ) were associated with adolescents who had depressive symptoms. Conclusions The detection rate of depressive symptoms is relative 26.86% among adolescents of Zhejiang Province. The students who are female, live on campus, have internet addiction, have been bullied or seriously injured, smoke and drink are more likely to have depressive symptoms.

Abstract: Objective　To investigate the prevalence and genetic characterization of Blastocystis in primary and middle school students in Baisha Li Autonomous County, Hainan Province, in order to understand the infection status of Blastocystis and its subtype distribution characteristics in this area. Methods　From March to November 2021, fecal samples were collected from two primary and middle schools in Baisha Li Autonomous County. Nested PCR targeting the SSU rDNA was employed in this study, sequence analysis were performed to determine the prevalence and subtype. A neighbor-joining tree was built using Mega 7. Meanwhile, the risk factors of the Blastocystis infection among different grades and genders were evaluated. Results　The infection rate of Blastocystis was 4.1% (13/314), there was no statistical difference in infection rates among genders and grades (P>0.05). Sequence analysis revealed that three Blastocystis subtypes were identified, namely ST3 (n=7), ST7 (n=4) and ST1 (n=2), all of which have zoonotic potential. Conclusions　This is the first report of the identification of Blastocystis in humans in Hainan at the subtype level, and provide the basic data for the prevention and control of Blastocystis in this area. The zoonotic subtypes identified in this area indicated more studies should be taken in humans and various animals, to better evaluate the transmission of Blastocystis and provide scientific support for the prevention and control of Blastocystis.

This study is to explore characteristic indexes in evaluation criteria for rat skin anaphylactoid test comparing skin blue spot OD values at the treated position and the control position in the same animal. Common contrast agents, traditional Chinese medicine injections and injections' active pharmaceutical ingredients or excipients in the existing clinical anaphylactoid reaction reports were taken as test drugs in the rat skin anaphylactoid test to define the K value: K > 2 represents positive anaphylactoid reaction, 1.2 ≤ K ≤ 2 represent doubtable anaphylactoid; K < 1.2 represents negative anaphylactoid reaction, which were taken as the criteria for evaluating anaphylactoid of tested drugs. The evaluation result and that for classic criteria were compared to study the applicability of K value. According to the comparison, K value, as the evaluation criteria in the rat skin anaphylactoid test, can more truly reflect the actual situation of skin aizen and minimize the error caused by animal individual factors. Compared with positive and negative two-level criteria for blue spot diameter, K value's positive, doubtable and negative three-level criteria are more objective and accurate. Therefore, K value can be used as the evaluation criteria in the rat skin anaphylactoid test.

OBJECTIVETo explore the effect of Shengjiang Xiexin Decoction (SXD) on the intestinal mucosal and functional cells of rats after irinotecan (CPT-11) chemotherapy.

METHODSTotally 24 healthy Sprague-Dawley (SD) male rats were divided into three groups, the normal control group, the CPT-11 group, the SXD combined CPT-11 group according to random digit table, 8 in each group. CPT-11 was injected at the daily dose of 150 mg/kg to rats in the CPT-11 group and the SXD combined CPT-11 group from the caudal vein on the 4th day, once daily for 2 successive days to duplicate delayed diarrhea model. Equal volume of normal saline was injected to rats in the normal control group from the caudal vein. SXD at 2 g/mL (10 g/kg body weight) was administered to rats in the SXD combined CPT-11 group by gastrogavage for 9 successive days. Deionized water was administered to rats in the CPT-11 group and the normal control group. Diarrhea was observed at 48, 60, 72, 84, 96, and 108 h to calculate the incidence rate of diarrhea. Meanwhile, scoring for diarrhea was performed by referring methods of Akinobu Kurita. Rats were killed on day 10, ileum, cecum, and colon tissues were collected and fixed in 10% formalin solution. HE staining was performed. Intestinal mucosa injuries were graded under light microscope according to the criterion of Chiu's score. The expressions of goblet cells and Paneth cells were observed by PAS stain. Enteroendocrine cells were observed by immunohistochemical CgA staining. Positive cells were counted and cumulative optical density (IOD) analyzed by Image-Pro-Plus 6.0.

RESULTSNo diarrhea occurred in rats of the normal control group at each time point. The incidence rate of diarrhea was 75.0% (6/8) at 48 h, 100.0% (8/8) at 60 h, 100.0% (8/8) at 72 h, 87.5% (7/8) at 84 h, 75.0% (6/8) at 96 h, and 75.0% (6/8) at 108 h in the CPT-11 group. The incidence rate of diarrhea was 25.0% (2/8) at 48 h, 50.0% (4/8) at 60 h, 12.5% (1/8) at 72 h, 0.0% (0/8) at 84 h in the SXD combined CPT-11 group. Compared with the same group at 60 h, scores for diarrhea at 48, 84, 96, and 108 h obviously decreased in the CPT-11 group, and scores for diarrhea at 48, 72, 84, 96, and 108 h obviously decreased in the SXD combined CPT-11 group (P < 0.05, P < 0.01). Compared with the same group at 72 h, scores for diarrhea at 84, 96, and 108 h obviously decreased in the CPT-11 group (P < 0.05, P < 0.01). Compared with the normal control group, scores for diarrhea increased in the CPT-11 group at each time point (P < 0.01); grading of ileum, cecum, and colon mucosal tissues increased (P < 0.05, P < 0.01); expressions of ileum and cecum mucosal epithelial goblet cells obviously decreased (P < 0.05); the number and expressions of ileum and cecum mucosal epithelial Paneth cells increased (P < 0.01). Expressions of ilium endocrine cells increased, while those of cecum and colon endocrine cells decreased in the CPT-11 group (P < 0.01). Compared with the CPT-11 group, scores for diarrhea were obviously lowered (P < 0.05, P < 0.01), grading of ileum, and cecum mucosal tissues decreased (P < 0.05, P < 0.01); expressions of ileum, cecum, and colon mucosal epithelial goblet cells obviously increased (P < 0.05, P < 0.01); the number and expressions of ileum cecum mucosal epithelial Paneth cells increased (P < 0.05); expressions of cecum and colon endocrine cells increased (P < 0.05, P < 0.01) in the SXD combined CPT-11 group.

CONCLUSIONSXD played roles in preventing and treating CPT-11 induced delayed diarrhea by improving CPT-11 chemotherapy induced apoptosis and necrosis of intestinal mucosal and functional cells.
