Research progress on the role of IGFs and EMT in gastric cancer / 中国肿瘤生物治疗杂志

@#胰岛素样生长因子（IGF）系统是人体内的一组多肽类物质，其分泌细胞广泛分布在人体各组织中，具有促生长作用。 IGF系统能够诱导肿瘤细胞出现EMT，进而增强肿瘤细胞干性、自我更新和转移潜能，向恶性肿瘤发展。研究显示，IGF系统的过 表达与胃癌（GC）的发生存在着密切关联，例如IGF-1和IGF-1R在GC组织中就有着明显表达，其表达水平随着GC从良性到恶性 的转变而逐渐増强。近年来研究也表明， 在GC细胞癌变的过程中，EMT起着关键性的作用，它使得肿瘤细胞具备了侵袭和迁移 能力，而削弱和抑制这种能力则成为了一种有针对性的治疗方法，这其中有着很大的研究空间。临床数据显示，患者化疗前后血 清中的IGF-1表达水平也能够直接反映化疗的效果，这更显示IGF可作为GC筛查的重要标志物， 为GC精准治疗的研究提供可 靠依据。上述一系列发现，使得IGF有望成为新的判断肿瘤发生及转移的诊疗指标。

Advances of omics analysis technology in precise diagnosis and treatment of tumor: from single level analysis to multi-omics integrative approaches / 中国肿瘤生物治疗杂志

@# Tumor is a complex systemic disease, involving abnormalities at multiple levels, such as DNA, RNA, protein and metabolite. According to the central rule, the derived omics methods are genomics, transcriptomics, proteomics and metabonomics. In the past few decades, there have been remarkable achievements in the single omics study of tumor, but the exact mechanism of tumor development is still unclear. In order to reveal the process of tumorigenesis and development in a more systematic way, the research of multiomics came into being, which promoted the transformation of tumor research paradigm from single parameter model to multi parameter system model. The integration of multi-omics methods is expected to clarify the mechanism of tumor occurrence and development, find biomarkers with diagnostic, prognostic and predictive performance, explore new treatment targets, and finally achieve predictive, preventive, and personalized medicine (PPPM). This paper reviews the research methods and progress of different omics techniques in tumor research, especially emphasizes the importance and scientific value of the integration of multiple omics techniques in tumor research and clinical related results.

Role of microRNA-126-5p in myocardial injury induced by doxorubicin / 中国病理生理杂志

AIM:To observe the expression of microRNA-126-5p during myocardial injury and its role in myo-cardial cell injury induced by adriamycin(also called doxorubicin, DOX).METHODS: The BALB/c mouse model of DOX-induced acute and chronic myocardial injury was established via intraperitoneal injection of DOX.HE staining was applied to observe the morphological changes of myocardial tissues.Lactate dehydrogenase(LDH)in serum was detected and PowerLab system was used to detect the influence of DOX on the changes of ±dp/dtmax.The expression of microRNA-126-5p in injured myocardial tissues and the H 9c2 cells exposed to DOX was detected by real-time PCR.Gain-and loss-of-function experiments were conducted to detect the role of microRNA-126-5p in H9c2 cells treated with DOX on LDH release and caspase-3 activation.RESULTS:In acute and chronic DOX myocardial damage models in mice,HE staining showed disarranged myocardial fibers, dissolved myofibril and inflammatory cell infiltration.Higher serum LDH level and lower ±dp/dtmaxin DOX-treated mice than those in normal mice were found.Compared with the normal mice, the expression level of microRNA-126-5p was significant increased in the myocardium with DOX-induced injury.Similarly,the expression level of microRNA-126-5p was significant increased in the H9c2 cells treated with DOX.In addition, over-expression of microRNA-126-5p decreased cell viability and promoted apoptosis,while microRNA-126-5p ablation promoted the viability and inhibited the apoptosis of H9c2 cells.CONCLUSION:The microRNA-126-5p expression is up-regulated in myocar-dial injury induced by DOX,and microRNA-126-5p inhibits cell viability and promotes apoptosis induced by DOX.

Influence of Inner Circular Sealing Area Impression Method on the Retention of Complete Dentures

The aims of the present study were to describe an impression method of "inner circular sealing area" and to evaluate the effect of the method on retention, aesthetics and comfort of complete dentures, which lack labial base for patients with maxillary protrusions. Three patients were subjected to the experiment, and two sets of complete maxillary dentures were made for each patient; the first set was made without labial base via an inner circular sealing area method (experimental group) and the second had an intact base that was made with conventional methods (control group). Retention force tests were implemented with a tensile strength assessment device to assess the retention and a visual analogue scale (VAS) was used to evaluate the comfort between the two groups. Results showed larger retention force, better aesthetics and more comfort in the experimental group. The improved two-step impression method formed an inner circular sealing area that prevented damage to the peripheral border seal effect of the denture caused by incomplete bases and obtained better denture retention.

O objetivo deste caso foi descrever um método de impressão por "área de selamento circular interno" e avaliar o efeito deste método na retenção, estética e conforto de próteses totais sem base labial para pacientes com protrusão maxilar. Três pacientes foram objeto desta experiência e foram feitas duas próteses maxilares completas para cada um deles; a primeira foi elaborada sem base labial pelo método de área de selamento circular interno (grupo experimental) e a outra teve uma base feita pelo método convencional (grupo controle). Foram realizados testes de retenção com estudo de tensão para avaliar a retenção e para avaliação do conforto dos dois grupos, foi empregada a escala analógica visual (EAV). Os resultados demonstraram que o grupo experimental apresentou força de retenção maior, estética melhor e mais conforto. O método modificado de impressão em duas etapas formou uma área de selamento circular interno que evitou danos ao selamento periférico causados por bases incompletas e obteve melhor retenção da prótese.

Research Progress in Identification Technology for Three Groups of Easily Confused Chinese Medicinal Materials / 中国药师

Many Chinese medicinal materials are difficult to be distinguished in characters resulting in easy confusion. In the pa-per, the basic concepts of three groups of easily confused Chinese medicinal materials ( schisandrae chinensis fructus and schisandrae sphenantherae fructus, phellodendri cortex and phellodendri amurensis cortex, akebiae caulis and clematidis armandii caulis) were illus-trated and the development of verification methods were reviewed in the respect of modern instrumental analysis technology. With the improvement of analysis technology, the identification of Chinese medicinal materials relies on experimental data instead of artificial ex-perience, which makes it more objective and accurate.

A combination of early warning score and lactate to predict intensive care unit transfer of inpatients with severe sepsis/septic shock

BACKGROUND/AIMS: The modified early warning score (MEWS) is used to predict patient intensive care unit (ICU) admission and mortality. Lactate (LA) in the blood lactate (BLA) is measured to evaluate disease severity and treatment efficacy in patients with severe sepsis/septic shock. The usefulness of a combination of MEWS and BLA to predict ICU transfer in severe sepsis/septic shock patients is unclear. We evaluated whether use of a combination of MEWS and BLA enhances prediction of ICU transfer and mortality in hospitalized patients with severe sepsis/septic shock. METHODS: Patients with severe sepsis/septic shock who were screened or contacted by a medical emergency team between January 2012 and August 2012 were enrolled at a university-affiliated hospital with ~2,700 beds, including 28 medical ICU beds. RESULTS: One hundred patients were enrolled and the rate of ICU admittance was 38%. MEWS (7.37 vs. 4.85) and BLA concentration (5 mmol/L vs. 2.19 mmol/L) were significantly higher in patients transferred to ICU than those in patients treated in general wards. The combination of MEWS and BLA was more accurate than MEWS alone in terms of ICU transfer (C-statistics: 0.898 vs. 0.816, p = 0.019). The 28-day mortality rate was 19%. MEWS was the only factor significantly associated with 28-day mortality rate (odds ratio, 1.462; 95% confidence interval, 1.122 to 1.905; p = 0.005). CONCLUSIONS: The combination of MEWS and BLA may enhance prediction of ICU transfer in patients with severe sepsis/septic shock.

Relationship between Serum TSH Level with Obesity and NAFLD in Euthyroid Subjects / 华中科技大学学报（医学）（英德文版）

To explore the relationship between serum thyroid stimulating hormone (TSH) level and obesity and nonalcoholic fatty liver disease (NAFLD) in euthyroid subjects,1322 subjects were subjected to a questionnaire survey and physical examination.Fasting blood samples were collected to test serum TSH,plasma glucose and lipids.Fatty liver was diagnosed by type B ultrasonography.The relationship between serum TSH level and body mass index (BMI),percentage of body fat and NAFLD was analyzed.The results showed that serum TSH level was significantly higher in females than in males at the same group,and it was significantly higher in overweight group than in control group.Levels of body weight,BMI,waist circumference and percentage of body fat were increased in TSH ＞2.5 group compared to TSH ≤2.5 group in women.However,plasma lipids showed no significant differences.In males all the parameters showed no significant differences between two groups.Serum TSH was significantly correlated with body weight,BMI,waist circumference and percentage of body fat after adjustment for age in females.Multiple linear regression analysis revealed that percentage of body fat and BMI contributed significantly to the variance of TSH.Serum TSH level was significantly higher in nonalcoholic fatty liver group than in normal group in females.Multiple logistic regression analysis showed that TSH level was not the independent risk factor of NAFLD.Taken together the data suggest that serum TSH in normal range is significantly correlated with BMI and percentage of body fat in females.And the change of TSH level would not influence the prevalence of NAFLD.

Endothelial nitric oxide synthase gene polymorphisms associated with susceptibility to high altitude pulmonary edema in Chinese railway construction workers at Qinghai-Tibet over 4 500 meters above sea level / 中国医学科学杂志(英文版)

<p><b>OBJECTIVE</b>To examine whether the polymorphisms of endothelial nitric oxide synthase (eNOS) gene are associated with the susceptibility to high altitude pulmonary edema (HAPE) in Chinese railway construction workers at Qinghai-Tibet where the altitude is over 4 500 m above sea level.</p><p><b>METHODS</b>A case-control study was conducted including 149 HAPE patients in the construction workers and 160 healthy controls randomly recruited from their co-workers, matching the patients in ethnicity, age, sex, lifestyle, and working conditions. Three polymorphisms of eNOS gene, T-786C in promoter, 894G/T in exon 7, and 27bp variable number tandem repeat (VNTR) in intron 4, were genotyped using polymerase chain reaction (PCR) and confirmed with DNA sequencing.</p><p><b>RESULTS</b>The frequencies of 894T allele and heterozygous G/T of the 894G/T variant were significantly higher in HAPE patients group than in the control group (P=0.0028 and P=0.0047, respectively). However, the frequencies of the T-786C in promoter and the 27bp VNTR in intron 4 were not significantly different between the two groups. Haplotypic analysis revealed that the frequencies of two haplotypes (H3,T-T-b, b indicates 5 repeats of 27 bp VNTR; H6, C-G-a, a indicates 4 repeats of 27 bp VNTR) were significantly higher in HAPE patients (both Pü0.0001). On the contrary, the frequencies of H1 (T-G-b) and H2 (T-G-a) were lower in HAPE patients than in healthy controls (both Pü0.001).</p><p><b>CONCLUSIONS</b>Two haplotypes (T-T-b and C-G-a) may be strongly associated with susceptibility to HAPE. Compared with the individual alleles of eNOS gene, the interaction of multiple genetic markers within a haplotype may be a major determinant for the susceptibility to HAPE.</p>

A Case of Pheochromocytoma Presented with Cardiogenic Shock and Followed by Spontaneous Remission

Pheochromocytoma is derived from the chromaffin cells and patients with pheochromocytoma present with several signs and symptoms by producing, storing and secreting catecholamine. Spontaneous rupture or necrosis of pheochromocytoma is extremely rare, but it can be lethal because of the dramatic change in the circulation such as an acute abdominal emergency or shock. Spontaneous remission of the clinical symptoms due to necrosis of the pheochromocytoma is rare. We describe such a case that presented with cardiogenic shock due to extensive necrosis of the pheochromocytoma and this was followed by spontaneous remission of the clinical symptoms without removal of the pheochromocytoma.

Clinical Study of Treatment of Group B Streptococcal Meningitis in Neonates

PURPOSE: Penicillin or ampicillin with aminoglycoside is the drug of choice for Group B streptococcal(GBS) meningitis in neonates. Some GBS meningitis, however, does not respond well to the treatment. The purpose of this study was to evaluate the efficacy of early penicillin treatment for the GBS meningitis in neonates. METHODS: Nineteen cases of GBS meningitis which was proven by CSF culture(13 cases) or latex agglutination test(17 cases) from 1999 to 2007 were retrospectively reviewed. In all cases 3rd-generation cephalosporin was initially given with ampicillin or aminoglycoside. Penicillin was added on the initial regimen according to the CSF results. Seven cases with penicillin given within 3 days of admission(early group) were clinically compared to the other cases(late or non-penicillin group). RESULTS: Fever continued for 3 to 23 days in the early penicillin group, for 2 to 23 days in the late penicillin group, and persisted in the non-penicillin group. Time needed for negative conversion of CSF bactigen or culture, however, revealed no statistical differences in those 3 groups. Vancomycin was effective in cases with poor responses to other antibiotics. CONCLUSION: Early penicillin treatment in combination with other antibiotics seemed to shorten the fever duration in the neonatal GBS meningitis.

Predictors of Transient Hypothyroidism in Neonatal Screening Test / 대한소아내분비학회지

PURPOSE: Congenital hypothyroidism is detected through the neonatal screening test and treated early from neonatal period. Among these patients, however, transient hypothyroidism is included. In this study, we aimed to evaluate the predicting factors of transient hypothyroidism in neonatal screening test. METHODS: We retrospectively reviewed medical records of 40 male and 31 female neonates diagnosed as congenital hypothyroidism by newborn screening from 1996 to 2003. The untreated cases that revealed slightly decreased levels of thyroid hormone on repeated examination and the cases who showed normalized hormone after 2 years of treatment were regarded as transient hypothyroidism. The results of neonatal screening tests and other clinical features of children with transient hypothyroidism were compared to those of children with permanent form. The time to normalization of thyroid hormone levels in the transient hypothyroidism were also reviewed. RESULTS: Among 71 cases of congenital hypothyroidism, 39 cases (54.9%) were transient and 32 cases (45.1%) were permanent hypothyroidism. There were no significant differences in clinical features between two groups, except lower birth weight in the transient group (transient 2.80+/-0.75 kg, permanent 3.22+/-0.57 kg, P=0.02). Free T4 levels were significantly lower and TSH levels were significantly higher in the permanent form than the transient ones (P<0.01). The estimated cut-off point for distinguishing transient hypothyroidism from permanent form was 2.05 ng/dL (sensitivity 54%, specificity 93%) for free T4 and 34 microIU/mL (sensitivity 72%, specificity 87%) for TSH. CONLCUSION: In this study, transient hypothyroidism could be differentiated from permanent hypothyroidism by TSH and free T4 levels of neonatal screening test. Repeated thyroid function tests are thought to be essential to make a diagnosis of not only transient but also permanent hypothyroidism.
