This study was aimed to evaluate the number of acute exacerbation of chronic obstructive pulmonary disease (COPD) and quality of life with family pulmonary rehabilitation exercise. Randomized controlled method 584 was used in the study. The COPD patients in the stability drug treatment were divided into the treatment group and control group. The treatment group A was given health education and pulmonary rehabilitation training in the family. And the treatment group B was given health education and treatment of pulmonary rehabilitation training in the family with acupoint application therapy. Health education was given in the control group. Changes on the number of acute exacerbation of COPD and quality of life were observed. The intervention time was one year. The results showed that patients after one-year pulmonary rehabilitation exercise in the family, the acute exacerbation (AECOPD) times of treatment group A and group B were obviously decreased (P < 0.01) compared to pre-treatment. The OR value was (0.79, 2.02) and (0.59, 2.11), respectively. The quality of life of treatment group A and group B was obviously improved (P < 0.05). The OR value was (3.39, 10.11) and (4.23, 9.57), respectively. Compared to the control group, the quality of life in treatment group B was obviously improved (P < 0.05). The OR value was (0.59, 7.78). It was concluded that the pulmonary rehabilitation exercise in the family can decrease the number of AECOPD and improve the quality of life of patients, reduce the risk of COPD patients in the future. This method is worth popularizing in the clinical and community practice.

Objective To establish diagnostic models for pancreatic carcinoma(PC)and to find out the biomarkers related to PC.Methods Serum samples obtained from subjects including PC patients,pancreatic benign disease patients and normal controls were examined with strong anionic exchange chromatography(SAX2)chips for protein profiling using surface enhanced laser desorption/ionization-time of flight-mass spectrometry(SELDI-TOF-MS).The decision tree models and logistic regression models for evaluating the value of serum biomarkers were assessed.SELDI immunoassay and ELISA were used to identify the biomarker and its level in serum respectively.Results Twentysix mass peaks were different between PC patients and normal controls(P＜0.0 1)and 16 mass peaks were different between patients with PC and with pancreatic benign disease(P＜0.05).The decision tree model had a sensitivity of 83.3%and a specificity of 100.0%in differentiation of PC,which was better than that of CA19-9 by ROC curve.There were significant differences in 6 mass peaks among different stages of PC(P＜0.01).Logistic regression model showed a sensitivity of 81.6%and a specificity of 80.6%in diagnosis of early PC.The M/Z 28068 protein was identified as C14orf166 with a sensitivity of more than 82%and a specificity of more than 88%in diagnosis of PC.Conclusions The diagnostic models based on SELDI-TOF-MS were superior to CA19-9 in diagnosis of PC.The identified biomarker C14orf166 is expected to play a role in the diagnosis of PC.

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.

Aim To study the interference role of Bcl-2 siRNA on HL-60 cells. Methods Bcl-2 siRNA was synthesized in vitro transcription with silencer siRNA construction kit. The synthesized siRNA was transfected into HL-60 cells with lipid siPORT transfection. Forty-eight hours after the transfection, we used MTT and immunofluorescence to detect cell proliferation and apoptosis,and used RT-PCR and immunofluorescence to detect the level of Bcl-2 mRNA and Bcl-2 protein expression. Result Bcl-2 siRNA reduced the level of Bcl-2 mRNA and Bcl-2 protein expression in HL-60 cells and induced cell apoptosis. There was no difference on the effect of other groups compared with the control. Effective Bcl-2 siRNA specifically degraded Bcl-2 expression in the levels of mRNA and protein and induced HL-60 cells apoptosis.Conclusion These results indicate that siRNA is a highly specific tool for targeted gene knockdown. siRNA-mediated gene silencing is a reliable approach for large-scale screening of gene function and drug target validation.

This study was aimed to investigate the effective on BODE index and traditional Chinese medicine (TCM) symptom scores with acupoint application therapy for patients of chronic obstructive pulmonary disease (COPD) in stabilization period of lung-spleen qi-deficiency syndrome. A total of 120 cases of inpatients and out-patients of the stable phase of COPD with TCM syndromes of lung-spleen qi-deficiency were selected. Conven-tional therapy was used in the treatment. All patients were divided into four groups, which are the hyperthermia plus acupoint application group, simple acupoint application group, simple hyperthermia group and blank control group. Each group contained 30 cases. All patients were given 6-week treatment. And the BODE index and TCM symptom scores were observed pre-treatment and post-treatment. The results showed that the BODE index was im-proved in the hyperthermia plus acupoint application group and the simple hyperthermia group. Symptoms of coughing, phlegm, wheezing, shortness of breath were reduced in all hyperthermia plus acupoint application group, simple acupoint application group and simple hyperthermia group. Symptoms of abdominal distention, spontaneous perspiration, easy to catch cold and cold sensation on the back were reduced in the group of hyperthermia plus acupoint application. Symptoms of spontaneous perspiration, easy to catch cold and cold sensation on the back can be improved in the group with simple hyperthermia. The symptom of spontaneous perspiration was improved in the group of simple acupoint application. It was concluded that acupuncture point application in combination with hy-perthermia therapy can significantly improve symptoms and quality of life, improve exercise tolerance in patients.

OBJECTIVETo explore the molecular basis for a novel B(A) phenotype.

METHODSGenomic DNA was abstracted from peripheral blood sample from the proband. ABO genotyping were carried out with sequence specific primer PCR (PCR-SSP). Exons 6 and 7 of the ABO gene were amplified with PCR and sequenced.

RESULTSAnti-A serum could not be adsorbed or eluted by the donor's red blood cells, and no irregular antibodies were found in the plasma. PCR-SSP showed that the ABO genotype of the donor was ABO *B/O. Sequencing results showed that one of the alleles was ABO *O02, while the other could not be defined but contained the following mutation points, 297A>G, 526C>G, 657C>T, 701C>T, 703G>A, 796C>A, 803G>C, and 930G>A. The data was accepted by the GenBank (the loading code was KM974887) and the Blood Group Antigen Mutation Database, and was confirmed to be a novel allele of B(A).

CONCLUSIONA novel allele ABO *B(A)07 with 701C>T has been identified, which may facilitate further study on blood antigen variants and typing of the blood groups.
