Clinical records of a patient with olfactory neuroblastoma presented with hyponatremia as initial symptoms were analyzed and the literatures were reviewed. At initial onset, the patient presented with hyponatremia. After pathological examination, the diagnosis was olfactory neuroblastoma. The blood sodium has been normal after operation and radiotherapy. The incidence rate of olfactory neuroblastoma is low, and it is easily misdiagnosed. Its diagnosis relies on pathological examination. We should pay more attention to the unspecific symptoms of patients with hyponatremia, which can help to improve early diagnosis and the prognosis.

Objective To investigate the correlation between QRS amplitudes and left ventricular wall thickness in autopsy specimens of elderly men.Methods The data of autopsy cases in our hospital since 1990 were retrospectively analyzed.The cases with QRS duration≥0.12 s and the pacing electrocardiogram were excluded.QRS amplitudes of standard 12-lead electrocardiography in 3 months before death were measured and the correlation between QRS amplitudes and left ventricular wall thickness was analyzed in the elderly men.Results Correlations were found between the amplitudes of the R waves in leads V5 ,V6, Ⅰ ,aVL[(1.1±0.7) mV, (0.95±0.6) mV, (0.44±0.3)mV and(0.35±0.3)mV] and left ventricular wall thickness[(13.6±5.4)mm;r=0.22,0.14,0.22,0.23,all P<0.05], and between the combination of QRS amplitudes SV1 +RV5 or RV6(1.9±1.2) mV] and left ventrieular wall thickness [(13.8± 5.4) mm; r = 0.23, P < 0.05].The correlationbetween the combination of QRS amplitudes (SV1 + RV5 or RV6 ) and left ventricular wall thickness was the strongest in 60-79 years old cases (r=0.48, P<0.01) ,and was decreased in 80-89 years old cases (r= 0.23, P<0.05).There was no correlation between the combination of QRS amplitudes (SV1+RV5or RV6) and left ventricular wall thickness in 90-101 years old cases (r= 0.03, P> 0.05).Conclusions Electrocardiogram is a reliable method for diagnosis of left ventricular hypertrophy in elderly men aged < 90 years.

Objective: To compare the efficacy difference between moxibustion at sensitized-acupoints and non-sensitized- acupoints using the same group of acupoints. Methods: A total of 139 patients with chronic superficial gastritis were divided into a sensitized acupoint group (102 cases) and a non-sensitized acupoint group (37 cases) based on whether acupoint sensitization occurred. The SPSS version 19.0 statistical software propensity score matching function was used to balance the baseline data between the groups. Finally, 29 pairs of matched patients were included, namely 29 cases in the sensitized acupoint group and 29 cases in the non-sensitized acupoint group. Both groups were treated with moxibustion therapy. The treatment lasted for 30 min per time, and was performed every other day for 8 weeks. Changes in the traditional Chinese medicine (TCM) symptom score and the short-form 36-item health survey (SF-36) score in both groups were observed before and after treatment, as well as the clinical efficacy. Results: The covariates of age, course of disease, TCM symptom score and SF-36 score in the two groups were balanced after matching (all P>0.05). After treatment, the total effective rate was 100.0％ in the sensitized acupoint group and 79.3％ in the non-sensitized acupoint group. The difference in the total effective rate between the two groups was statistically significant (P<0.01). After treatment and at the 4-week follow-up, the TCM symptom scores in the sensitized acupoint group were significantly lower than those in the non-sensitized acupoint group (all P<0.01); the SF-36 scores in the sensitized acupoint group were significantly higher than those in the non-sensitized acupoint group (all P<0.01). Conclusion: With the same group of acupoints, the sensitized acupoints have a better therapeutic effect and long-term efficacy than the non-sensitized acupoints in the treatment of chronic superficial gastritis.

This study was aimed to detect and identify the promoter CpG island methylation of γ-globin gene in peripheral blood mononuclear cells from patients with β-thalassemia major and healthy adult in Guangxi province, as well as to analyze the difference of promoter methylation rate of each CpG sites between them, and then to screen the promoter CpG island main methylation sites which maybe influence γ-globin expression. The template DNA was modified by bisulfite genomic sequencing PCR; the promoter sequences of γ-globin gene were amplified by technique Touchdown PCR, and then the PCR products were cloned and sequenced for obtaining methylation status of each CpG sites in target fragments, and then the accurate methylation sites and levels were detected quantitatively. The results indicated that the 4 CpG methylation sites locating at 28, 122, 231 and 234 bp in sequences were hypermethylated. As compared with healthy adults, the DNA methylation rate of 122 and 231 bp CpG sites in patients with β-thalassemia major was obviously lower, however, methylation rates of 28 and 234 bp sites were not significantly different between patients and healthy adults. It is concluded that the methylation sites 28, 122, 231 and 234 bp of γ-globin gene promoter are found both in patients with β-thalassemia major and healthy adults. The 122 and 231 bp sites are identified preliminarily to be involved in the regulation of γ-globin expression. This study provides the experimental evidence for alleviating the clinical symptoms of β-thalassemia major and targeting gene treatment through the regulation of γ-globin.

BACKGROUND: Individual three-dimensional (3D) scaffolds can be constructed by 3D printing via Computer Aided Design based on the given anatomical measurements of related tissues. A rapid and accurate reconstruction of bone, cartilage, muscle and vessel also can be achieved by 3D printing; however, many problems still remain unsolved.OBJECTIVE: To summarize the principle and classification of 3D printing, the classification, characteristics and histocompatibility of scaffolds through reviewing the articles addressing 3D printing applied in bone tissue engineering,thereby providing theoretical foundation for the study on the construction of tissue-engineered bone.METHODS: PubMed and CNKI databases were retrieved for the literatures regarding the application of 3D printing technology in bone tissue engineering published from January 2001 to January 2017 using the keywords of three-dimensional printing, rapid prototyping manufacturing, bone tissue engineering in English and Chinese,respectively. Finally, 30 articles were reviewed and discussed in accordance with the inclusion and exclusion criteria.RESULTS AND CONCLUSION: The microstructures of normal tissues can be reconstructed and seed cells are printed on the 3D scaffolds synchronously by 3D printing technology. Moreover, the scaffold degradation and cell differentiation are synchronous, which contributes to tissue repair. Biological ceramics have been widely used in bone tissue engineering because of its good biocompatibility and mechanical properties. However, the urgent problems such as angiogenesis and cellular signal transduction still need to be addressed.
