A study on patients’negative emotional reactions and its influencing factors at the diagnosis of pulmonary tuberculosis / 预防医学

Objective To investigate patients’negative emotional reactions and its influencing factors when pulmonary tuberculosis (PTB ) was diagnosed, and to provide evidence for health education and intervention. Methods A questionnaire survey was conducted among 440 PTB patients who were treated at the designated clinics of two counties in Zhejiang Province.Twenty patients at one clinic were randomly selected for a semi-structured interview.Results A total of 437 qualified questionnaires were collected and 19 patients were successfully interviewed.When they were told the result of diagnosis,58.58% patients felt worried,29.75% were shocked,20.37% tended to blame themselves,10.98% felt helpless and 35.70%had a sense of shame.In the semi-structured interview,the main reasons for negative emotions told by the patients were disbelieving the fact of getting the disease and misunderstanding TB was incurable.Old people felt more shocked (40.26%),worried (58.44%)and self-blaming (38.96%)about the diagnosis of TB.The divorced and widowed expressed more reactions of worry (95.24%), shock (6 1.09%), self -blame (6 1.09%), helpless (42.86%).Farmers had higher rate of shock (48.89%),worry (70.37%),and self-blame (43.70%).Conclusion Negative emotions or feelings were popular among TB patients when the disease was diagnosed.The elders,divorced or widowed people and farmers need to be attached more importance during the process of health education or intervention.

Analysis of the parental origin of MECP2 mutations in patients with Rett syndrome / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To identify the parental origin of methyl-CpG-binding protein 2 (MECP2) gene mutations in Chinese patients with Rett syndrome.</p><p><b>METHODS</b>Single nucleotide polymorphisms (SNPs) in intron 3 of the MECP2 gene were analyzed by PCR and sequencing in 115 patients with Rett syndrome. Then sequencing of the SNP region was performed for the fathers of the patients who had at least one SNP, to determine which allele was from the father. Then allele-specific PCR was performed and the products were sequenced to see whether the allele from father or mother harbored the mutation.</p><p><b>RESULTS</b>Seventy-six of the 115 patients had at least one SNP. Three hot SNPs were found in these patients. They were: IVS3+22C >G, IVS3+266C >T and IVS3+683C>T. Among the 76 cases, 73 had a paternal origin of MECP2 mutations, and the other 3 had a maternal origin. There were multiple types of MECP2 mutation of the paternal origin, including 4 frame shift, 2 deletion and 67 point (56C >T, 6C >G, 2A >G, 2G >T and 1A >T) mutations. The mutation types of the 3 patients with maternal origin included 2 frame shift and 1 point (C >T) mutation.</p><p><b>CONCLUSION</b>In Chinese RTT patients, the MECP2 mutations are mostly of paternal origin.</p>

Profile-effect on quality control of Houttuynia cordata injection / 药学学报

<p><b>AIM</b>To find corresponding relationship between the fingerprint of Houttuynia cordata injections from different factories and their effects.</p><p><b>METHODS</b>Houttuynia cordata injections from six different factories were determined by gas chromatography (GC) and gas chromatography-mass spectra (GC-MS), and GC fingerprints were classified by hierarchical clustering. The anti-inflammatory activity of Houttuynia cordata injections was characterized through the rat pleurisy model induced by carrageenin and the mice ear edema model by dimethylbenzene.</p><p><b>RESULTS</b>The anti-inflammatory effect of the injections from the first class factories on the two model was significant, while those from the second class not. GC-MS analysis result indicated that main effect compounds in Houttuynia cordata injections are methyl n-nonyl ketone, decanoylacetaldehyde, lauryl aldehyde, capryl aldehyde, beta-pinene, beta-linalool, 1-nonanol, 4-terpineol, alpha-terpineol, bornyl acetate, n-decanoic acid and acetic acid, geraniol ester etc.</p><p><b>CONCLUSION</b>There is corresponding relationship between the fingerprint of Houttuynia cordata injections and effect to a certain extent.</p>
