ABSTRACT

Objective To analyze the epidemiological characteristics of hand-foot-mouth disease(HFMD)in Gan-zhou.Methods The epidemiological data of HFMD reported by the Infectious Disease Surveillance System,a sub-system of China Disease Prevention and Control Information System,from 2017 to 2020 were analyzed by descriptive methods.Enterovirus(EV)nucleic acid and typing detections via throat swabs,anal swabs or herpes fluid of patients was detected by real-time fluo-rescent polymerase chain reaction.The change in HFMD epidemic characteristics was compared between 2020 and 2017-2019.Results The incidence of HFMD in Ganzhou in 2020 was significantly lower than that from 2017 to 2019(x2=50.587,P<0.05).In 2020,the incidence of HFMD in counties and districts of Ganzhou(except Huichang County)signifi-cantly decreased compared with that in 2017-2019(P<0.05).From 2017 to 2019,the incidence of HFMD was obviously seasonal,with a high incidence in summer and autumn,and two significant incidence peaks were formed in June and September in 2017 and 2018,respectively.In 2019,there was a summer peak in June.The epidemic trend in 2020 was different,with a very low epidemic trend in summer and autumn,and a peak in winter.The incidence of HFMD in men,women and all ages in 2020 significantly decreased compared with that in 2017-2019(P<0.05),and the age of onset was mainly distributed in 1-5 years,especially in children aged 1 to 3 years.There was a significant difference in the incidence of HFMD among different ages(P<0.05).The positive rate of EV in Ganzhou in 2020 was lower than that from 2017 to 2019(x2=47.273,P<0.05).The positive rate of EV in January,March to September in 2020 was significantly lower,and the positive rate of EV in November,December 2020 was significantly higher than that in the same period in 2017 to 2019(P<0.05).Strain CA16 showed an increasing trend year by year from 2017 to 2019,and became the dominant strain in 2019.The proportion of patients infected with CA6 strain was on the fise from 2018 to 2020,and CA6 became the dominant strain in 2020.Conclusion The HFMD in Ganzhou has obvious population characteristics and seasonality,and the pathogen spectrum is constantly changing.

ABSTRACT

cFos is one of the most widely-studied genes in the field of neuroscience. Currently, there is no systematic database focusing on cFos in neuroscience. We developed a curated database-cFos-ANAB-a cFos-based web tool for exploring activated neurons and associated behaviors in rats and mice, comprising 398 brain nuclei and sub-nuclei, and five associated behaviors: pain, fear, feeding, aggression, and sexual behavior. Direct relationships among behaviors and nuclei (even cell types) under specific stimulating conditions were constructed based on cFos expression profiles extracted from original publications. Moreover, overlapping nuclei and sub-nuclei with potentially complex functions among different associated behaviors were emphasized, leading to results serving as important clues to the development of valid hypotheses for exploring as yet unknown circuits. Using the analysis function of cFos-ANAB, multi-layered pictures of networks and their relationships can quickly be explored depending on users' purposes. These features provide a useful tool and good reference for early exploration in neuroscience. The cFos-ANAB database is available at www.cfos-db.net .

ABSTRACT

Objective To determine the expression of Pim-1 in hepatocellular carcinoma patients and its relationship with oncogene c-Myb.Methods From January 2009 to October 2013,136 patients with hepatocellular carcinoma (HCC) who were received surgical treatment at department of hepatobiliary surgery,the first affiliated hospital of the fourth military medical university,were selected to collect the clinical data,resected liver cancer tissues and para cancerous tissues,and complete the follow-up work.The patients were followed up by outpatient review or telephone.The deadline for follow-up was June 28,2017.To the end of the study,14 cases were lost,and 122 cases of HCC were included in this study.At the same time,85 cases of normal liver tissues which were obtained from hepatic hemangioma in the same period were collected as normal control group.The expression of Pim-1 and c-Myb protein detected in these liver tissues was detected by immuno-histochemical (IHC) staining.Western-blotting test was used to detect the expression of Pim-1 protein in human hepatoma cells SMMC-7721,HepG2,Hep3B,Huh7,MHCCL,MHCC-97H and normal human hepatocytes L-02,HL-7702.The average number of two samples was compared by Student's t test.The count data were analyzed by chi-square test or Spearman correlation analysis.Results The total positive expression rate of Pim-1 protein in liver cancer tissues was 88.5% (108/122),which was significantly higher than that of para cancerous tissues 73.0% (89/122) and normal liver tissues 69.4% (59/85) (x2 =9.513,P =0.003;x2 =11.739,P =0.001).The total positive expression rate of c-Myb was 96 cases,of which 88 cases were positive for Pim-1 and c-Myb.Spearman correlation analysis showed that the expression of Pim-1 protein and c-Myb protein in HCC tissues was positively correlated (r =0.107,P =0.037).Compared with L-02 and HL-7702 cells,the content of Pim-1 in the cells of human hepatoma cells SMMC-7721,HepG2,Hep3B,Huh7,MHCCL,MHCC-97H increased significantly (P <0.01).Conclusions The expression level of Pim-1 in hepatocellular carcinoma tissues and hepatocellular carcinoma cells increased significantly,and it was correlated positively with the expression of proto oncogene c-Myb.This is closely related to the occurrence and development of HCC.

ABSTRACT

Objective The aim of this study was to determine the expression of Pim-1 in primary hepatocellular carcinoma (PHC)and its clinical significance. Methods Immunohistochemical staining(IHC) was used to detect the expression of Pim-1 in 122 cases of PHC tissues,corresponding paracancer tissues,and 85 normal liver tissues. The relationship between the expression of Pim-1 protein and clinicopathological parameters was analyzed retrospectively. K-M method was used to analyze the effect of differ-ent Pim-1 expression on the survival time of PHC patients. Cox proportional hazard regression models were used to analyze risk fac-tors affecting survival time in patients with PHC. Results The total positive expression rate of Pim-1 protein in PHC tissues was 88. 5% ,which was significantly higher than that in adjacent tissues and normal liver tissues(P<0. 05). Univariate statistical analysis showed that patients with high expression of Pim-1 protein had poor preoperative liver function,more tumors,larger tumor diameter, high incidence of lymph node metastasis and high TNM stage(P<0. 05). Survival analysis suggested that the survival time of patients in the low expression group was significantly longer than that in the high expression of Pim-1 group(P<0. 05). Multivariate statisti-cal analysis showed that high expression of Pim-1 protein was an independent risk factor for survival time in patients with PHC(P<0. 001). Conclusion The expression level of Pim-1 in PHC tissues is significantly increased,which is related to the clinical pro-gress of PHC and the survival time of patients. Pim-1 overexpression indicates the poor prognosis of PHC patients.

ABSTRACT

Many studies have proven that arsenic trioxide (As2 O3 )as a single agent is not effective against hepatocellular carcinoma (HCC).Many scholars believe that chemotherapy drug resistance of HCC to As2 O3 is the most important reason.The underlying drug resistance mechanism of HCC cells to As2 O3 remains unclear.Studies show that potential mechanism may be tightly associated with As2 O3 pharmacokinetics and properties of HCC tissues and complex molecular biology.

ABSTRACT

Objective: To explore change of hemoglobin (Hb) concentration, the relationship between anemia and left ventricular function and the influence of anemia on prognosis in patients with diastolic heart failure (DHF). Methods: According to NYHA classification, a total of 176 DHF patients were divided into class Ⅱ group (n=78), class Ⅲ group (n=50) and class Ⅳ group (n=48), then Hb level and morbidity rate of anemia were analyzed in each group. According to diagnostic standard of anemia, patients were divided into anemia group (n=58, , occupied 33.0%) and non anemia group (n=118, occupied 67.0% ). Left ventricular diastolic function, mortality rate and rehospitalization rate during follow-up were compared and analyzed between two groups. Results: Along with cardiac function class rose (from class Ⅱ to class Ⅳ), Hb level showed a decreasing trend [(130±6) g/L vs. (108±4) g/L vs. (96±12) g/L], while morbidity rate of anemia gradually rose (8.97% vs. 36.0% vs. 68.8%), P<0.05 all in anemia group;Compared with non-anemia group, there were significant rise in percentages of patients with coronary heart disease (55.1% vs. 65.5%), levels of creatinine [(87.6±39.2) μmol/L vs. (113.7±59.8) μmol/L] and N terminal pro B type natriuretic peptide [NT-proBNP, (578.0±136.7) pg/ml vs. (886.0±174.8) pg/ml], and early-diastolic peak velocity deceleration time [(137±15)ms vs. (196±13)ms], and significant reduction in mitral early/late diastolic peak flow velocity [E/A, (0.87±0.32) vs. (0.62±0.29)], P<0.05 all. Compared with non-anemia group, there were significant rise in mortality rate (9.3% vs. 20.7%) and rehospitalization rate (18.6% vs. 32.8%) in anemia group during follow-up, P<0.05 all. Conclusion: DHF patients often complicate with anemia. Along with heart failure aggravates, their morbidity rate of anemia rises, and anemia may aggravate cardiac diastolic dysfunction. Mortality rate and rehospitalization rate rise in DHF patients complicated with anemia.

ABSTRACT

Objective To study the role of homeobox A2(HOXA2) gene in cell growth,cellcycle and apoptosis of hepatoma cells, and discuss the feasibility that HOXA2 gene would be a potential therapy target of hepatoma. Methods Real-time quantitative polymerase chain reaction and revers transcriptional polymerase chain reaction were performed to examine HOXA2 expression in tumorous and non-tumorous tissue of patients was matched with liver cancer. siRNAs were chemically synthesized to interference HOXA2 in PLC/PRF/5 and MHCC-97L cells. Growth curve and soft-agar colony formation assay were performed to evaluate cell growth, and cell cycle and apop-tosis were analyzed by flow cytometry. Results HOXA2 was upregulated in HCC samples compared with matched non-tumor tissues(P<0.05). Two siRNAs against HOXA2 gene were designed and synthesized to specially knock-down HOXA2 in PLC/PRF/5 and MHCC-97L cells. HOXA2 knockdown inhibited cellular growth and soft-agar colony formation in PLC/PRF/5 and MHCC-97L cells. And Fowcytometry analysis revealed that HOXA2 knock-down by RNA interference could result in G1 arrest and S decrease and promoted cellular apoptosis. ConclusionHOXA2 gene has an important role in cell growth of hepatoma cells.

ABSTRACT

Objective To investigate the clinical effect of Gonadotropin-releasing hormone agonist (GnRHa) combined with addback therapy after laparoscopic surgery on 153 cases with severe endometriosis patients. Methods 153 cases with severe endometriosis patients who underwent laparoscopic surgery from 2011 to 2013 were retrospectively analyzed in the Second Affiliated Hospital of Zhengzhou University. According to GnRHa or addback therapy three groups were divided:GnRHa group,GnRHa and addback therapy group, control group. The curative effects of different treatment group, adverse reactions, recurrence rates, and fertility were analyzed. The follow-up time was 6-24 months with an average time of 17.15 months. Results 51 patients suffered from obvious menopausal symptoms and received addback therapy (Progynova,0.5~1 mg/d). The VAS score and Kupperman score in GnRHa group,GnRHa and addback therapy group were significantly superior to the control group (P 0.05). The VAS scores in the GnRHa group and addback therapy group were 2.14±2.02 and 1.73±2.17 , respectively (P > 0.05). The main side effect of GnRHa group is hot flashes, diaphores, insomnia, sexual dysfunction, etc. The incidences were higher in the GnRHa group than that in the addback therapy group. But the addback therapy can significantly relieve the symptoms of low estrogen introduced by the application of GnRHa (P<0.05). Conclusions Laparoscopic combined with GnRHa treatment can significantly improve clinical curative effect of endometriosis. Addback therapy could abate the side reaction of GnRHa and do not affect the clinical curative effect. The clinical curative effect in the GnRHa and addbacktherapy group were superior to the GnRHa group.

ABSTRACT

BACKGROUND: Now, dual-energy X-ray absorptiometry is international y recognized as gold standard for the diagnosis of osteoporosis, but the errors can be found in the measurement results due to the heterotopic ossification and bone hyperplasia exists in the measurement part. OBJECTIVE: To investigate the clinical significance of bone metabolic markers in the diagnosis and treatment of elderly patients with osteoporotic fractures, and to research its correlation with the changes of pathological histology and bone mineral density. METHODS: Four bone biochemical markers in 50 elderly patients with osteoporosic fractures were measured preoperatively. According to the results, 25 patients had significantly increased tartrate-resistant acid phosphatase 5b (considered as the increased tartrate-resistant acid phosphatase 5b group), and 25 patients had increased bone alkaline phosphatase (considered as the increased bone alkaline phosphatase group). During operation, the bone tissues of eight patients in each group were treated with hematoxylin-eosin staining and electron microscopy scanning in order to detect the pathological changes. After operation, the patients in the increased tartrate-resistant acid phosphatase 5b group received salmon calcitonin anti-osteoporosis treatment, and the patients in the increased bone alkaline phosphatase group received the anti-osteoporosis treatment of bone peptide injection. The bone mineral density and the four bone biochemical markers were detected again at 6 months after treatment. RESULTS AND CONCLUSION: There were no significant differences in the preoperative bone mineral density and four biomechanical markers between two groups (P > 0.05). The pathological examination results of bone tissue on the fracture site showed that the number of osteoblasts was reduced and the number of oeteoclasts was increased in the increased tartrate-resistant acid phosphatase 5b group; while in the increased bone alkaline phosphatase group, the pathological examination results showed the number of osteoblasts was reduced; the trabecular bone/bone area ratio was decreased in two groups, and there was a significant difference in the decrease degree between two groups (P < 0.05). The electron microscope scanning showed that the osteoclasts of two groups were more active than that of the normal group. The sloppy of trabecular bone in the increased tartrate-resistant acid phosphatase 5b group was more obvious than that in the increased bone alkaline phosphatase group, and the absorption vacuoles were increased. There were significant differences in the bone mineral density and four biomechanical markers between two groups before and after anti-osteoporosis treatment (P < 0.05). The detection of bone metabolic markers could help us to make it clearly that the main function of osteoblast reduce or osteoclast increase in bone tissue of patients, and guide us to use anti-osteoporosis drugs in target. Pathological histology examination can better reflect the condition of osteoblasts, osteoclasts and trabecular bone in bone tissue on the fracture site. Target application of anti-osteoporosis drugs in the osteoporosis patients can effectively improve the efficacy and reduce the relative complications.

ABSTRACT

Objective: To evaluate the predictive value of plasma amino-terminal pro-B-type natriuretic peptide (NT-proBNP) on short term prognosis in patients with acute coronary syndrome (ACS). Methods: Plasma NT-proBNP levels were measured in ACS patients within 24 h after admission with ELISA method. The 600 ACS patients were divided into two groups: event group (n=108)and no-event group (n=492)according to occurrence of cardiovascular events(including cardiac death, cardiac shock and heart failure), The NT-proBNP levels were compared between two groups. Single factor and multiple factor Logistic regression analyses were used to evaluate if NT-proBNP was an independent predictor for short term prognosis. Results: The plasma NT-proBNP levels of event group were significantly higher than those of no-event group [1361.2 (965.3, 2088.6) pmol/L vs.605.7 (274.5, 1177.8) pmol/L, p<0.01]. Multiple factor Logistic regression analyses demonstrated that plasma NT-proBNP was an independent predictor for short term prognosis (OR=1.000, p<0.01) in ACS patients. Conclusion: Plasma NT-proBNP was an independent predictor for short term prognosis in ACS patients.
