Viable but non-culturable state in bacterial cells as received uncultured microorganism has be- come the fundamental research issues in medical microbiology, epidemiology, general microbial ecology and sanitation quarantine since it was put forward in 1982. When in this state, bacterium are no longer able to grow and form colonies on conventional culture media, but maintain their patheogenicity, may become latent infection escaping detection to threaten enviroment and human security. With the development of modern molecular biology technique and metagenomics, it provide new research method and opportunity for uncul- tured microorganism in the environment. Recently, with the application of the metagenome technique, ge- netic fingerprinting technical etc, it becomes more and more popular. Simultaneously, along with this state become maturity in the laboratory. It provides a new research route for development and exploitation the uncultured microorganism.

Objective To explore the changes of plasma brain natriuretic peptide(BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP)of sepsis combined with myocardial injury in newborns.Methods According to neonatal sepsis treatment program,45 cases of sepsis newborns in NICU of the Second Hospital in Lanzhou University from Jul.2007 to Jun.2008 were collected.According to the myocardial injury diagnostic criteria,45 cases neonatal sepsis were divided into myocardial injury group(n=22) and non-myocardial injury group(n=23).Myocardial injury group was also divided into congenital heart disease group and non-congenital heart disease group accor-ding to echocardiography.At the same time,30 healthy newborns were collected as healthy control group.Every newborns were tested the level of plasma BNP,NT-proBNP,creatine kinase-MB(CK-MB) and cardiac-troponin I (cTnI).Results There were significant difference between myocardial injury group,non-myocardial injury group and healthy control group in the levels of plasma BNP,NT-proBNP,CK-MB and cTnI,those in congenital heart disease group were higher than those in non-myocardial injury group and the healthy control group(Pa0.05).Conclusions BNP and NT-proBNP can be early used to diagnose myocardial injury and heart failure of neonatal sepsis associated with CK-MB and cTnI.In NICU,infants with sepsis should normally test BNP and NT-proBNP in order to early diagnose myocardial injury of neonatal sepsis.

Objective:To discuss the significance of standardized treatment for cancer pain, according to the Cancer Pain Treat-ment Specification (2011 Edition) issued by the Ministry of Health, PR China. Methods:Clinical data of 126 patients with cancer pain, who were admitted to the Department of Medical Oncology, The Fourth Hospital of Hebei Medical University, were collected to com-pare the improvement of the Numeric Rating Scale (NRS) score, number of breakthrough pain, and quality of life score after treatment. The relationships between different pain grades, disease entities, and treatment effect were analyzed. The influence factors of pain relief were also analyzed by using Logistic regression analysis. Results:1). Following standardized treatment, the improvement rate of NRS score has shown significant differences in pain grading (P=0.001) and gender (P=0.000). However, no significant differences were ob-served between different diseases (P=0.112). The improvement rate of the life quality score and the number of breakthrough pain had no significant difference after standardized treatment. 2). The grading of cancer pain and the disease entities had little effect on cancer pain relief. 3). The anti-tumor treatment and“no distant metastasis”were the independent factors that brought about the decrease in NRS and quality of life scores.“No distant metastasis”(P=0.046) was the independent factor that reduced the number of pain out-breaks. Conclusion: The standardized treatment positively affects the NRS score, number of breakthrough pain, and quality of life score. Patients who received anti-neoplastic therapy and who had no distant metastasis showed significant treatment effectiveness in pain management.

Objective To evaluate the diagnostic and differentiable value of video-electroencephalogram(VEEG)in sleeping-related seizure disorder.Method Sixty-five cases with sleeping-related seizure disorders(35 suspected epilepsy and 30 suspected non-epileptic seizure)enrolled in our clinics from Jan.2005 to Jun.2006 were examined by VEEG and EEG.Results Among 35 children suspected to have the possibility of epilepsy,the epileptic discharge rate examined with VEEG was 62.86%(22/35),which were significantly higher than that by EEG was 17.14%(6/35)(P

Objective To investigate the clinical pathologic significance of lymphangiogenesis in in colorectal cancer. Methods New lymphatic-specific markers D2-40 was used immunohistochemically to detect the lymphatic vessel density(LVD) in the intratumoural and peritumoral areas, and in normal tissue from 96 cases of colorectal cancer, which were analyzed with clinical pathologic parameters of those colorectal cancer. Results Significandy higher LVD was found in the intratumoural area(14.5±2.4), when compared with normal(5.9±1.1)and peritumoural areas(6.7±1.2) (P<0.01). LVD of the peritumoural area was higher than normal area (P< 0.01). However, peritumoural LVD was associated with both depth of invasion and liver metastasis (r=0.71,0.78 P<0.05), but not associated with tumour size, macroscopic type and lymph-node metastasis (P>0.05). Intratu-moural LVD was not correlated with tumour size, macroscopic type, the depth of invasion,lymph-node metastasis, and liver metastasis(P>0.05). Conclusion Lymphangiogenesis in the peritumoural area may be helpful in evalution of liver metastasis and prognosis.

Objective To estimate the impact of universal salt iodization on child intelligence quotient (IQ) development in Hainan province. Methods In this is a cross-section study from September in 2008 to April in 2009,the observation group was historical iodine deficiency ward which includes 2 counties and 6 townships,and the control group was non-historical ward which includes 6 counties and 9 townships. Comparison of child IQ distribution according to different geographical housing position(plain,mountainous area,coast),age and sex based on the result of urine iodine examination and the IQ test of children between 8 and 10 years old. Results The median of urinary iodine of children in the observation group was 196.2μg/L which was 2.13 times of the urinary iodine median in the control group(91.9μg/L). The average IQ of children in the observation group was 94.7 which was 8.5 higher than the control group(86.2) ; IQ≤69 rate in this group was 7.7%(91/1179),and it was 8.9 percentage point lower than the control group[16.6%(253/1520)]; IQ≥ 110 rate of the group was 18.3%(216/1179),and it was 10.0 percentage point higher than the control group[8.3%(126/1520)]. The average IQ of children living in mountainous area(83.1) was the lowest in the control group. It was 3.5 and 5.1 lower than that of the children living in the plain(86.6) and coastal area(88.2) respectively; the IQ≤69 rate of children living in mountainous area [20.5%(91/443)]was the highest,and it was 3.8 and 7.1 percentage point higher than that of the children living in the plain [16.7% (89/533)]and coastal areas [13.4% (73/544)]respectively. The average IQ of children aged 8 (97.4) was similar to those aged 9(95.9) in the observation group which was 6.8 and 5.3 higher than that of the children aged 10(90.6) in the same group respectively; However,the average IQ of children aged 8,9 and 10 was close in the control group(86.8,86.3 and 85.6). The average IQ of boys(96.2) was 3.1 higher than that of the girls(93.1),and their IQ≤69 rate[6.3%(37/590)]was 2.9 percentage point lower than that of the girls[9.2% (54/589)]in the observation group. On the other hand,the average IQ(87.2) of boys was 2.1 higher than that of the girls(85.1),and IQ≤69 rate[14.5%(114/787)]was 4.5 percentage point lower than that of the girls [19.0%(139/733)]in the control group. The average IQ of children with different housing geographical position,age and sex in observation group was 5.0-12.4 higher than that of the control group; their IQ≤69 rate was 7.7-13.2 percentage point lower than that of the control group; their IQ≥110 rate was 5.6-13.0 percentage point higher than that of the control group. Conclusions Supplementing salt iodization can improve child intelligence. Supplementing iodine can increase the child IQ and reduce the child mental retardation.

Objective To explore the feasibility of the application of non fasting blood lipid in the hospitalized population.Methods Self-control study was used.608 patients(aged 20~86 years old) were enrolled from April 2015 to October 2016 in lipid center of FuWai hospital.Fasting sample and non-fasting sample(1~4 h after breakfast) were collected from every patient and lipid profile including TG (triglyceride), TC (total cholesterol), HDL-C (high density lipoprotein cholesterol) and LDL-C (low density lipoprotein cholesterol) were measured in clinical laboratory.The results of two tests were compared using the Wilcoxon signed-rank test.Results The differences between non-fasting and fasting lipid test were +0.47 mmol/l (+30%) for TG,-0.03 mmol/l (-2.8%) for HDL-C,-0.09 mmol/l (-3%) for LDL-C and-0.24 mmol/l (-8.7%) for calculated LDL-C (P<0.001 respectively).The differenceswere +0.01 mmol/l for TC and +0.02 mmol/l for non-HDL-C,therefore no statistical difference was observed.When the TG level was stratified,the level of non-fasting LDL-C using directing test method was not significantly different between TG> 4.5 mmol/L and the whole (0.07 vs.0.09),but the level of non-fasting LDL-C using formula method wassignificantly different between TG> 4.5 mmol/L and the whole (0.66 Vs.0.24),andthe drops were 34.9% vs.8.7%.Conclusion Non-fasting lipid test could be an effective routine method for lipid evaluation in the hospitalized population.
