Objective To establish a drug-resistance cell line of human glioma with temozolomide ( TMZ) ,investigate its resistance mechanisms, and provide experimental evidence for optimal TMZ therapy. Methods A TMZ-resistant human glioma cell line,U251/TR,was established by stepwise exposure of human parental U251 cells to TMZ. Resistance index and cell viability were accessed by MTT assay. Western-Blot,RT-PCR,immunohistochemistry and immunofluorescence were used to detect MGMT expression for the analysis of resistance mechanism. Results A TMZ-resistant human glioma cell line,U251/TR,was developed after 8 months of stepwise induction with 0. 25-16. 00 μg·mL-1 TMZ. IC50 in U251/TR cells was approximately 7 times higher compared with that in U251 cells (P=0. 00 ). The MGMT expression was significantly increased in U251/TR cells compared with that in parental U251 cells (P=0. 00) . Conclusion A TMZ-resistant human glioma cell line,U251/TR,was established by stepwise exposure of human parental U251 cells to TMZ. The primary mechanism of TMZ resistance is associated with increased activity of MGMT.

Patrolling monocyte (PMo) is a subset of monocytes.Its main function is patrolling vascular endothelium and removing cellular debris from the microvasculature.Studies have revealed that PMo can inhibit the growth of tumor cells,recruiting NK cells to kill tumor cells.PMo can prevent tumor cells metastasis to the lung,which plays a role of immunosurveillance.PMo may be a target for cancer immunotherapy.

Objective To identify a myeloid differentiation factor 88(MyD88)in Oncomelania hupensis,and characterize the role of MyD88 against Schistosoma japonicum infection. Methods The complete cDNA of MyD88 in O. hupensis was ob-tained by using rapid amplification of cDNA ends(RACE),and homologues sequences and conserved domains were aligned and the structure of MyD88 was predicted either. A phylogenetic tree of MyD88 was further constructed with other species. In ad-dition,the mRNA expression level of O. hupensis MyD88 before and after S. japonicum infection was investigated by real-time quantitative PCR(RT-qPCR). Results The cDNA of O. hupensis MyD88 consisted of 1406 bp open reading frame(ORF),en-coding 468 amino acid residues,which contained death domain and Toll/interlrukin-1 receptor(TIR)domain,the typical fea-tures of MyD88 family proteins. The predicted amino acid sequence of O. hupensis MyD88 shared 38%-52%identity with other mollusc. O. hupensis MyD88 was phylogenetically closeted to Biomphalaria glabrata MyD88. The O. hupensis MyD88 existed in all selected tissues and expressed highly in hemocyte,up-regulated after S. japonicum infection in all selected tissues except cephalopodium,especially higher in whole snail and hemocyte. Conclusion MyD88-dependent signaling pathway is present in O. hupensis and plays an important role in innate immune response against S. japonicum infection.

Objective To study the morphological character of blood-spleen barrier in patients with hypersplenism,and to discuss the relevance and pathogenesis of hypersplenism.Methods The spleens of 33 patients with cirrhosis with portal hypertension were collected as the experimental group,and 20 patients with traumatic spleen as the matched group.Five pieces of tissues in each spleen were sampled.The samples were made into pathological sections,stained with H.E.and examined microscopically for the total number of germinal centers (GC).The data of patients before operation were collected which included:blood routine (count of RBC,WBC,PLT and HB) and splenic weight.The correlation of blood routine values and sum of GC was studied using relative linear analysis.Results In the experimental group:The blood routine values were remarkably lower,splenic weight (average 764.2 g) and the quantity of the germinal center (average 8817/case) were higher.There was a reverse relationship between the total quantity of germinal centers and the PLT.There was a close relationship between the quantity of germinal center and the extent of the hypersplenism,i.e.the lower the preoperative platelet number,the greater the total number of germinal center; the heavier the splenic weight,the greater the number of germinal center.Conclusions The total number of germinal center increased dramatically in patients with cirrhosis with portal hypertension.The change is accompanied by changes in morphology of the germinal centers and dysfunction in blood-spleen barrier.It is likely that hypersplenism develops on the basis of dysfunction of blood-spleen barrier.

Objective To analysis the correlation of obstructive sleep apnea-hypopnea syndrome (OSAHS) and perihematoma edema of hypertensive cerebral hemorrhage.Methods One hundred and forty-four patients with hypertensive cerebral hemorrhage were collected and 78 of these patients were suffered from OSAHS.The patients were divided into two groups,control and OSAHS group,according to whether were accompanied by OSAHS or not.Both of the groups received the routine treatments including dehydration,reducing blood press,protecting the cerebral cells and so on.Cerebral CT scan was taken on admission.Night polymonography (PSG) was done within 24 hours of admission.Twenty-four hours and 4 days after admission,cerebral CT scan was taken again.The volumes of cephalophyma and perihematoma edema were calculated according to the results of CT scan.The changes of cephalophyma and perihematoma edema were dynamic observed.Results No difference in patients' age,sex,body mass index,serum glucose,blood lipid and so on,was observed between the two groups.The relative edema index became significantly different until 4 days after admission (0.40 ± 0.45,0.96 ± 1.35 in control and OSAHS group respectively,t =4.149,P =0.000).Similarly,the alternation edema index of OSAHS was obviously higher than that of control group only in 4 days after admission.While the analysis of the correlation between different degree OSAHS groups and edema indexes showed that at 24 hours after admission the edema volumes for different degree OSAHS groups were consistent (1.05 ± 0.65,0.84 ± 0.48,1.20 ± 0.54,1.10 ±0.40 in control,slight,moderate and severe groups respectively,F =1.061,P =0.374).At 24 hours and 4 days after admission,the edema volumes were positively correlated with the degree of OSAHS.Alternation edema index was significantly correlated with apnea hypopnea index according to the result of Pearson' s correlation analysis (r =0.652,P =0.000).Conclusion OSAHS complication can promote the progression of perihematoma edema of hypertensive cerebral hemorrhage,and the degree of edema aggravation is positive correlated to the degree of OSAHS.

Objective To explore the efficacy and safety of dyclonine hydrochloride mucilage applied as a lubricant for orotracheal intubation. Methods A prospective study was conducted,144 patients with respiratory failure(RF)and clear consciousness admitted into Emergency Department of Xingtai People's Hospital in December 2010 to June 2013 for orotracheal intubation were randomly divided into experimental and control groups(each, 72 cases). Topical spray anesthesia onto the throat wall was applied for all the patients before orotracheal intubation. In the experimental group,the patients received 1%hydrochloric acid dyclonine mucilage as a lubricant,while in the control group,they received paraffin oil as a lubricant before the insertion of tracheal tube. The operating procedure of the insertion was in accord to the rules of orotracheal intubation in both groups. The changes of heart rate,systolic blood pressure,diastolic blood pressure,pulse oxygen saturation(SpO2),success rate of once tracheal intubation,incidence of choking cough,the time of tracheal intubation and dyclonine adverse reactions were observed. Results The heart rate,systolic and diastolic blood pressures were significantly higher and SpO2 was obviously lower after the intubation in both groups than those before the procedure,and the changes were more significant in the control group〔heart rate(bpm):135.2±9.9 vs. 98.1±8.1,systolic blood pressure(mmHg,1 mmHg=0.133 kPa):145.6±20.8 vs. 138.8±22.1,diastolic blood pressure(mmHg):96.1±17.6 vs. 82.9±22.8,SpO2:0.643±0.128 vs. 0.749±0.102, all P<0.05〕;the success rate of once tracheal intubation in experimental group was significantly higher than that in the control group〔98.6%(71 cases)vs. 84.7%(61 cases),P<0.01〕,the incidence of choking cough was obviously lower than that in the control group〔36.1%(26 cases)vs. 52.8%(38 cases),P<0.05〕,the time for insertion of tracheal tube in experimental group was also significantly shorter than that of control group(minutes:1.9±0.9 vs. 2.3±1.1,P<0.05). No drug adverse reactions occurred. Conclusion Compared with paraffin oil,dyclonine hydrochloride mucilage as a lubricant for tracheal intubation is a simpler and easier operation which has the advantages of having better anesthesia,effectively reducing the irritation of the throat wall,improving the success rate of intubation,being more tolerable by the patients,reducing the adverse reaction rate during insertion of tube and having no occurrence of drug adverse reactions,therefore dyclonine can be applied in tracheal intubation.

OBJECTIVE: To study the characteristics of coronary arteriography and traditional Chinese medicine syndrome of 1,069 patients with coronary artery disease (CAD). METHODS: One thousand and sixty-nine patients with CAD were investigated by epidemiological method. The patients were divided into young patients (n=82, aged 45 years or younger) and middle-aged and old patients (n=987, older than 45 years). The characteristics of the two groups were analyzed, including clinical data, coronary arteriography and traditional Chinese medicine syndrome. RESULTS: Compared with middle-aged and old patients, proportion of male, triglyceride, total cholesterol, smoking patients, acute myocardial infarction and family history of CAD in young patients were significantly higher (P<0.05). Patients accompanying with hypertension and diabetes in middle-aged and old patients were more than those in young patients (P<0.05). Occurrence rates of morbidity of left circumflex coronary artery, left main coronary artery and multi-branch were higher in middle-aged and old patients (P<0.05), however, the occurrence rates of morbidity of single and double-branch were higher in young patients (P<0.05). The occurrence rates of syndromes of qi stagnation and phlegm turbidity in young patients were higher than those in middle-aged and old patients (P<0.05). But the proportions of cold coagulation, yin deficiency, yang deficiency and kidney deficiency in middle-aged and old patients were obviously higher (P<0.05). CONCLUSION: The traditional Chinese medicine syndrome and pathological changes of CAD in young patients are different from those in old patients.

OBJECTIVE: To explore the effect of the traditional Chinese medicine Yifei Kangliu (YFKL) Oral Liquid on the proliferation, cell cycle and protein-nucleic acid synthesis of murine Lewis lung cancer cell and human lung adenocarcinoma cell line SPC-A-1. METHODS: The inhibiting rates of tumor growth were calculated by weighing the weight of tumor inoculated in vivo, combined by counting cancer cells in vitro. The ratio of the cell cycle and exponents of DNA, RNA, and protein were measured by flow cytometry (FCM). RESULTS: The inhibiting rate of tumor growth in the treated group with YFKL Oral Liquid was 30.38% (P<0.05). The proportion of cells in S phase of the treated groups with YFKL Oral Liquid was lower than that of the control group. In the group with most significant result, 72% of the cells were stagnated in G0/G1 phase. The inhibiting rates of DNA, RNA and protein in murine Lewis lung cancer were 7.4%, 23.73% and 23.31% respectively. In SPC-A-1 cell line, the inhibiting rates were 9.3%, 10.1% and 14.7% respectively, demonstrating amplified effects on lower levels. CONCLUSION: YFKL Oral Liquid significantly inhibited the proliferation of murine Lewis lung cancer cell and human lung adenocarcinoma cell line SPC-A-1 by blocking the cancer cells entering the proliferative phase resulted from its inhibition of DNA.
