ABSTRACT
Objective:To explore the impact of continuous nursing education on the quality of life, psychological state and satisfaction of patients with inflammatory bowel disease based on micro-video.Methods:In chronological order, 83 patients with inflammatory bowel disease (hospitalized from January to June, 2019 in Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology) were divided into two groups, the control group with 42 cases (discharged from the hospital from January to March, 2019) carried out regular telephone continuing nursing education and the intervention group with 41 cases (discharged from hospital from April to June, 2019) were provided the continuous nursing education in the form of telephone plus micro-video. Before intervention and after 3 months of intervention, quality of life, levels of anxiety and depression and nursing satisfaction were evaluated by inflammatory bowel disease questionnaire (IBDQ), Self-rating Anxiety Scale(SAS), Self-rating Depression Scale(SDS), digital table method and compared between the two groups.Results:There was no significant difference in quality of life, levels of anxiety and depression before intervention between the two groups( P>0.05). After 3 months of intervention, the scores of IBDQ, SAS, SDS were 155.1±23.7, 58.7±15.1, 59.5±11.1 in the intervention group and 115.7±21.7, 71.5±16.7, 72.8±12.0 in the control group, the differences between the two groups were statistically significant ( t values were 7.910, 3.642, 5.223, P<0.01). The nursing satisfaction score was 89.32±6.34 in the intervention group and 81.45±7.21 in the control group, the difference between the two groups was statistically significant ( t value was -5.284, P<0.01). Conclusions:Continuous nursing education in the form of micro-videos can increase the quality of life of the inflammatory bowel disease patients, improve mental state and their nursing satisfaction in further.
ABSTRACT
Objective: To analyze the correlation of CT enhancement degree and pathology of pancreatic ductal adenocarcinoma (PDAC), and to observe its value for prognostic assessment. Methods: Data of 150 patients with PDAC confirmed by pathology were retrospectively analyzed. All patients underwent preoperative CT plain scanning and double period (parenchymal phase and portal phase) enhanced scanning of pancreas. The CT value difference of PDAC and peripheral pancreatic parenchyma (parenchymal phase and portal phase CTpancreas-tumor), as well as that of tumor enhancement and plain scan (CTparenchymal phase-plain phase, CTportal phase-plain phase) were measured. Correlation of all CT value differences and pathological differentiation or content of fibrous stroma within PDAC were observed, and the independent impact factors of survival time of PDAC patients were analyzed. Results: There was a moderate correlation between parenchymal phase CTpancreas-tumor and pathological differentiation but low correlation among the remaining CT value differences and pathological differentiation of PDAC (all P<0.05). Parenchymal phase CTpancreas-tumor was negatively correlated with content of fibrous stroma (r=-0.51, P<0.05). Tumor differentiation, lymph node metastasis and surgical margin status were independent risk factors of survival time of PDAC patients (all P<0.05). Conclusion: Parenchymal phase CTpancreas-tumor of PDAC was negatively correlated with pathological differentiation and content of fibrous stroma. The smaller CT value difference indicates, the lower pathological staging and the longer survival time were.
ABSTRACT
Objective@#To analyze the variation characteristics of HIV-1 Gp120 sequences in men who have sex with men (MSM) in Guangzhou.@*Methods@#Plasma samples were collected from HIV-1 infected MSM before antiretroviral treatment. Viral RNA was extracted from plasma. Gp120 gene sequences were amplified by reverse transcription and nested-PCR using specific primers. Phylogenetic tree, length polymorphism, amino acid characteristics of V3 loop, co-receptors and signature amino acids were analyzed.@*Results@#The phylogenetic tree were divided into 4 clusters, and the most prevalent subtypes were CRF07_BC (34/61, 55.74%) and CRF01_AE (24/61, 39.34%). Majority of HIV-1 Gp120 sequences had 496-515 amino acids. Among five hypervariable regions, the V1 region had the highest levels of length polymorphism and V3 region had the lowest. The top four peptide of V3 loop were GPGQ (56/58, 96.55%). Most of the co-receptors HIV-1 strains used was CCR5(50/58, 86.21%)according to four methods of comprehensive prediction. There are four signature amino acids in CRF01_AE subtype strains, and the frequency of occurrence was 0.75-0.83; there are eight signature amino acids in CRF07_BC subtype strains, and the frequency was 0.74-0.94.@*Conclusions@#The length of Gp120 sequences in MSM in Guangzhou has a high polymorphism. The top four peptide of V3 loop, co-receptor and signature amino acid of V3 ring have formed unique patterns.
ABSTRACT
Objective To investigate the genetic variations of gag-pol gene in human immunodeficiency virus-1(HIV-1) CRF07_BC strain in Guangdong Province.Methods From February to September in 2015,plasma samples of 78 cases with HIV 1 CRF07_BC infection in Guangdong were collected before antiretroviral treatment.Viral RNA was extracted from plasma.Gene (gag and pol) sequences were amplified by reverse transcriptase and nested-PCR using specific primers.Phylogenetic tree,genic dispersion rate,nucleotide polymorphism,selection pressure and variation characteristics were analyzed.Results The main transmission route of the enrolled patients was homosexual transmission (80.77％,63/78).The gag pol gene phylogenetic tree was divided into two sub-clusters.The strains from different transmission routes were not in cluster.The average genetic dispersion rate and average entropy of gag gene were both higher than those of pol gene.The average genetic dispersion and average entropy of p17 and p6 regions of gag gene were both higher than those of p24.The average genetic dispersion and average entropy of pol gene were higher than those of rt region.The average ds/dn values of gag and pol genes were greater than one.Compared with the common HIV-related antigenic epitopes (A2,A11,B39,B60,Cw1,Cw3,Cw8),the cytotoxic lymphocyte (CTL) epitope mutations in the P17 region were more in the consensus of GAG region than those in the P24 region.The epitope conserved rates were 26.92％,0,1.28％,0,96.15％,82.05％,84.62％ and 98.72％,respectively.The drug resistance rate of pol gene was 2.56％ (2/78).Conclusions The gag and pol genes of CRF07_BC strain in Guangdong are all mutated.Diversity of gag gene is greater than that of pol gene,and gag gene variation is mainly in p17 and p6 regions.gag and pol genes are both affected by negative selection pressure.P17 protein CTL epitope variability is greater than P24 protein epitope.The prevalence of drug resistance mutation is lower than the threshold.It's important to monitor the spread of drug-resistant strains.
ABSTRACT
OBJECTIVE:To provide reference for the development of pharmaceutical care for periconceptional women. METH-ODS:Probability proportionate to size sampling(PPS)method was adopted to select participants from periconceptional women in Yongchuan District. The participants were investigated by questionnaires about drug use safety knowledge,attitude and behavior. Ep-idata 3.0 software was used to establish database. The data were analyzed with SPSS 15.0 software. RESULTS:Totally 800 ques-tionnaires were distributed and then 779 valid questionnaires were collected with effective rate of 97.38%. The total awareness rate of knowledge about drug use safety was 57.69%. The awareness rate rise with the increase of educational level (P<0.01). The awareness rate was higher in pregnant women than in prepregnant ones,with statistical significance in most of the questions(P<0.05 or P<0.01). For questions about attitude for drug use safety,the positive answer rate was higher in pregnant women than in prepregnant ones,with statistical significance in most of the questions (P<0.01). Among 385 pregnant women,only 56.88% re-ceived folic acid following the WHO recommendation. Of 181 pregnant women who had taken medicine,8.29% indicated that the physicians or pharmacists did not inform that whether the medicine affected pregnancy. CONCLUSIONS:Among periconceptional women,awareness rate of drug use safety is in low level and varied by their educational levels. There are difference in awareness rate of drug use safety and attitude between prepregnant women and pregnant woman. Drug use behavior of pregnant woman is to be modified.
ABSTRACT
Objective To investigate the prevalence and characteristics of non-nucleoside reverse transcriptase inhibitors (NNRTIs)resistance-related gene mutations among the AIDS patients with virological suppression failure in Guangdong Province 2015.Methods Plasma samples from AIDS patients receiving highly active antiretroviral therapy for more than one year with viral loads > 1000 copies/mL from Guangdong province (except Shenzhen)were collected from January to December 2015.Total 612 HIV-1 gene fragments were amplified from plasma samples using self-developed lab method.Sub-genotypes were determined by phylogenetic tree according to the sequences,NNRTIs resistance-related mutations were determined in Stanford University HIV-1 Drug Resistance Database. The NNRTIs-resistance, the relationships of NNRTIs resistance-related mutations with baseline CD4 +T lymphocyte counts,transmission routes,antiviral regimens and HIV-1 genotypes were analyzed.SPSS 17.0 software was used to analyze the data.Results In 612 patients with virological suppression failure,the main NNRTIs resistance-related mutations were K103 (26.80%),Y181 (14.71 %),V179 (13.73%),G190 (11 .44%) and V106 (10.62%).The susceptibility rate of 310 patients (50.65%)to NNRTIs had changed,the highly resistant rate to nevirapine was 49.51 %,which was higher than that of efavirenz (43.14%),etravirine (5.56%) and rilpivirine (12.25%),respectively,and the differences were statistically significant (χ2 =5.00,296.3 and 198.0,all P 200 cells/μL was lower than that in those with baseline CD4 +T lymphocyte counts <200 cells/μL (χ2 =17.93,P <0.01 );the incidence rate of drug resistance was lower in intravenous drug abusers than that of sexually transmitted patients (χ2 =44.21 ,P <0.01 );while the incidence of drug resistance in patients receiving NVP-containing regimens was higher than that in those receiving EFV-containing regimens (χ2 =8.93,P <0.01 ),and the incidence rate was higher in patients with CRF01 _AE than that in those with CRF07_BC and CRF08 _BC (χ2 =8.46 and 8.47,P <0.01 ).Conclusions The results suggest that compliance education and follow-up should be strengthened in patients with high baseline CD4 +T lymphocyte counts and intravenous drug users,and patients with liver diseases should avoid using drugs containing NVP regimens.
ABSTRACT
Objective To study the effects of RNA interference(RNAi)-mediated silencing of mitofusin-2 (Mfn2) gene on glycornetabolism and insulin resistance in BALB/c mice. Methods Mfn2 short hairpin RNA (shRNA) and negative control green fluorescent protein(GFP) -expressed plasmid vectors were constructed. 44 mice were randomly divided into transfection group (Mfn2) and negative control group (HK). 1.5 ml GFP-expressed plasmid(negative control or Mfn2 shRNA,75 μg for each mouse)was injected into the mice in 5 seconds through vena caudalis. Five days later, intraperitoneal glucose tolerance test (IPGTT) and intraperitoneal insulin tolerance test(IPITT)were performed to evaluate glycometabolism and insulin sensitivity. D-3-[3~H]-glucose in PBS buffer were injected via the tail vein. Blood samples were taken at specific time points. Radioactivity was measured in all samples with liquid scintillation counter. The rates of hepatic glucose production in vivo were calculated. Mfn2 protein expression in hepatic tissue was detected by Western blot. Results Compared with HK mice, the Mfn2 expressions of Mfn2 mice decreased markedly(8.05±0.15 vs 8.56±0.01 ,P<0.05). The fasted blood glucose leves [(6.95±0. 83 vs 4.68±0. 29) mmol/L,P<0. 05] in Mfn2 mice were higher than those in HK mice. The insulin sensitivity of Mfn2 mice decreased markedly compared with HK mice. The rate of hepatic glucose production was significantly elevated in Mfn2 mice [(49.53±16.31)μmol·kg~(-1)·min~(-1)],compared with negative control mice[(24.91±4.07)μmol·kg~(-1)·min~(-1),P<0.05].Conclusion The down-regulatd expression of Mfn2 induces glycometabolic disorder and insulin resistance in BALB/c mice. Mfn2 plays an important role in maintaining glucose homeostasis in vivo.
ABSTRACT
Objective To investigate the safety of novopen needle after repeated uses in order to save the expenses of patients. Methods 60 diabetic patients undergoing insulin therapy were random-ized into the common temperature group and the refrigerated storage group. The novopens were stored at common temperature in a clean and dry place, while the refrigerated storage group was stored in cold clos-et of a refrigerator. Oropharyngeal swab bacterial culture was used to compare the incidence of infection in two groups on the first, third, fifth, and seventh days. Results There was no bacterial growth in either storage condition. Conclusions The novopen needle can be repeatedly used in clinic work.But they must be used individually. Storage at common temperature or in a refrigerater can reach the same effect.
ABSTRACT
Insulin sensitivity,β-cell function and serum high-sensitivity C-reactive protein (hs-CRP)levels were observed in obese and non-obese normoglycemic first-degree relatives of type 2 diabetic patients (FDR). The results showed that there existed insulin resistance,β-cell dysfunction and increased serum hs-CRP level in obese FDR of type 2 diabetic patients. Moreover, insulin resistance and increased CRP level were positively related to waist circumference.
