Objective To study the mechanisms of Hydroxycamptothecin (HCPT) induced apoptosis of gastric cancer cells by detecting the expressions of p53, c myc, bcl 2, bcl xl, bcl xs genes. Methods Apoptosis of gastric cancer cells (SGC 7901,MKN 45) was measured by TUNEL and flow cytometry. The levels of mRNA and protein of p53, c myc, bcl 2, bcl xl,bcl xs genes were determined by reverse transcriptase polymerase chain reaction analysis and immunohistochemistry, respectively. Results Gastric cancer cells SGC 7901, MKN 45 presented some morphologic features of apoptosis, including cell shrinkage, nuclear condensation, DNA fragmentation, formation of apoptotic bodies, after 12 hours expourse to HCPT. Some typical subdiploid peaks before G0/G1 phase were observed. The apoptotic rates of SGC 7901, MKN 45 were 21.88% and 12.34%, respectively. The levels of p53 and bcl 2 mRNA and protein were downregulated after treated with HCPT in SGC 7901 cells. The levels proteins of c myc, bcl xl, bcl xs were unchanged after expourse to HCPT in SGC 7901 cells. The levels of p53 mRNA and protein were increased after treated with HCPT in MKN 45 cells. While the expressions of protein of bcl 2, c myc, bcl xl, bcl xs genes were not affected by HCPT in MKN 45 cells. Conclusion The results have showed HCPT induced apoptosis in gastric cancer cells might be regulated through influencing the expressions of p53 and bcl 2 genes.

Objective To construct recombinant plasmid pEGFP C1 antisense survivin and than transfect it to MKN 45 gastric cancer cells for studying the expression of survivin mRNA and its effects on apoptosis of cancer cells. Methods Recombinant pEGFP C1 antisense survivin plasmid was cloned and transfected to MKN 45 gastric cancer cells by lipofectamine. Apoptosis of gastric cancer cells was assayed by flow cytometry. The levels of survivin mRNA before and after transfection were determined by reverse transcription polymerase chain reaction analysis. Results After recombinant pEGFP C1 antisense survivin plasmid was transfected, the apoptosis of MKN 45 cells was increase, the cell number in G 2/M phase was decreased, and the level of survivin mRNA was inhibited. Conclusions pEGFP C1 antisense suvivin can promote the apoptosis of MKN 45 gastric cancer cells, that might attribute to the inhibition on cell proliferation and expression of survivin mRNA.

Objective Through gene reconstruction we generated pcDNA 3-survivin-mutant(Cys84Ala)plasmid, then the plasmid DNA was further transfected into gastric carcinoma cells by liposomal delivery. The effects of mutant survivin on cytokinetics of the gastric carcinoma cells were obversed. Methods By using immunohistochemical staining, the expression of survivin was detected in the gastric cancer tissues, and apoptosis was detected by flow cytometry. The PARP and cytochrome C expressions were determined by Western blot, the mitotic catastrophe was determined by immunofluorescence. Results Inhibition of survivin by mutant survivin cDNA could induce apoptosis, increase caspase-3 activity, cleave PARP and promote cytochrome C release in gastric cancer cells. Inhibition of survivin also caused mitotic catastrophe in gastric cancer cells. Conclusion Inhibition of survivin may induce apoptosis and mitotic catastrophe in gastric cancer. Survivin targeting gastric cancer therapy might be of potential benefit in the future.

Objective:To explore the effect of family integrated care (FIC) combined with intelligent health education platform in health education for elderly patients with stroke.Methods:Eighty patients with stroke were included from the Department of Neurology of the Second Affiliated Hospital of Chongqing Medical University from June 2019 to May 2020. They were divided into the experimental group and the control group ( n=40, respectively) by the random number table method. Patients in the control group received routine FIC in the Department of Neurology. Additional intelligent health education platform was provided for the experimental group to carry out intensive education. The modified Barthel index scale, self-care compliance scale and hospital anxiety and depression scale (HADS) were used before and after the intervention to evaluate patient′s self-care ability, self-care compliance and the degree of anxiety and depression. Results:Finally, 39 patients in the experimental group (1 case lost to followed-up) and 37 patients in the control group (3 cases lost to followed-up) completed the study. After the intervention, the scores of the modified Barthel index and self-care compliance scale of the experimental group were significantly higher than those of the control group [(65.9±12.6) vs (60.1±11.9) points, (78.2±13.6) vs (71.4±14.6) points], the HADS score was significantly lower than the control group [(15.18±2.46) vs (19.46±2.40) points] (all P<0.05). The scores of the modified Barthel index scale and self-care compliance scale of the experimental group after the intervention were significantly higher than those before the intervention [(65.9±12.6) vs (40.8±12.5) points, (78.2±13.6) vs (54.6±15.9) points] (all P<0.05), the HADS score was significantly lower than before the intervention [(15.18±2.46) vs (21.74±3.52) points] (all P<0.05). Similarly,the scores of the modified Barthel index and self-care compliance scale of the control group after the intervention were significantly higher than before the intervention [(60.1±11.9) vs (41.6±9.72) points, (71.4±14.6) vs (54.3±14.8) points], the HADS score was significantly lower than before the intervention [(19.46±2.40) vs (21.38±3.09) points] (all P<0.05). Conclusion:FIC combined with intelligent health education platform can significantly improve the self-care ability and self-nursing compliance of elderly stroke patients, and markedly improve the degree of depression and anxiety.

Objective To quantify the expressions of collagen metabolic markers carboxy terminal propeptide of type I procollagen(PICP),nitrogen terminal propeptide of type I procollagen (PINP),nitrogen terminal propeptide of typeⅢprocollagen(PⅢNP),type I collagen carboxy terminal telopeptide (ICTP), matrix metalloproteinases(MMPs)and the tissue inhibitor of metalloproteinases(TIMPs)in the serum of atrial fibrillation patients by enzyme linked immunosorbent assay(ELISA),and to discuss the atrial structural remodeling during atrial fibrillation(AF).Methods 71 elderly patients were enrolled,24 patients had permanent AF,24 patients had paroxysmal AF,and 23 patients were in sinus rhythm.The serum levels of all markers were measured by ELISA. Results PICP was increased in permanent AF group versus the paroxysmal AF group and sinus rhythm group by 25.4%and 42.8%(all P<0.05),respectively.PⅢNP was increased in permanent AF group versus the paroxysmal AF group and sinus rhythm group by 17.9a% and 35.6%(all P<0.05),respectively,and was increased in the paroxysmal AF group versus the sinus rhythm group by 15.0%(P<0.05).PINP and ICTP did not differ significantly between the 3 groups(all P >0.05).MMP-1 was significantly increased by 25.6%(P<0.05)in the paroxysmal AF group versus the sinus rhythm group.MMP-2 was also significantly increased in permanent AF group versus the paroxysmal AF group and sinus rhythm group by 54.9%and 37.9%(all P<0.05),respectively.MMP-7,MMp-9 and TIMP-1 did not differ significantly between the 3 groups(P>0.05).TIMP-2was significantly decreased in the permanent AF group and paroxysmal AF group versus the sinus rhythm group by 21.8%and 11.8%(P<0.05),respectively. Conclusions Disturbance in the balance of MMP/TIMP system may perturb the balance of collagen synthesis and degradation during atrial fibrillation.This may be a contributing mechanism to atrial structural remodeling in atrial fibrillation,and may correlate with the initiation and maintenance of AF.

Objective To explore the value of EUS in the diagnosis,differential diagnosis and follow-up of primary gastric lymphoma(PGL).Methods A total of 26 patients whose endoscopic findings were highly suspected for PGL were enrolled in this study.Initial endoscopic examination anti routine biopsy were performed in all patients.EUS were undergone in all cases and its guided large piecemeal biopsy was administered in selected patients.The results of EUS,routine biopsy and routine biopsy combined with a large piecemeal biopsy were compared.Results Compared with biopsy and histopathological results,EUS made the fight diagnosis in 23 cases with overall accuracy of 88.46%,which was significantly superior to routine endoscopy and biopsy(50.0%,P=0.006),but was slightly lower than that of routine biopsy combined with large piecemeal biopsy(88.5%vs.92.3%,P=1.000).EUS can accurately differentiate gastric malignancy from benign disease with accuracy of 100.0%(23/23).Meanwhile EUS accuracy of tumor invasion(T stage)was 100.0%(12/12)as well.Conclusion EUS is valuable in the diagnosis,differential diagnosis and follow-up of PGL.

Objective To evaluate contrast-enhanced endoscopic uhrasonography(CE-EUS)in the differential diagnosis of pancreatic diseases.Methods Eighteen patients with suspected pancreatic neoplasms and chronic pancreatitis,which would be finally affirmed with EUS-FNA or histophathologic examinations,as well as five normal control subjects were enrolled and underwent CE-EUS by using ultrasonic contrast agent(sonovue,Bracco Co.,Italy).Characteristics of enhancement including form,echo and enhanced blood perfusion of the target areas were investigated in normal pancreas and various diseased ones.Results By CE-EUS,five cases of normal pancreatic parenchyma were presented as punctiform or claviform enhancement pattern with homogeneous distribution(type Ⅰ-Ⅱ);while two chronic pancreatitis cases were presented as claviform or plaquelike enhancement pattern with inhomogeneous distributition(type Ⅱ-Ⅲ).In addition,thirteen pancreatic carcinomas were presented as inhomogeneous punctiform or claviform enhancement(typeⅠ-Ⅱ)partially with border enhancement and with slow enter-in and fast wash-out phase.However,three benign insulinomas were presented as holo-plaquelike enhancement(type Ⅲ),and 2 with fast enter-in and fast washout phase.Besides,different enhancement intensity was identified in different diseases.Conclusion CEEUS,from which different enhancement pattern,phase and intensity would be shown in various pancreas,is a safe and feasible imaging modality in the differential diagnosis of pancreatic diseases.
