ObjectiveTo investigate the current situation of intensive care unit (ICU) inpatients in Infectious Disease Hospital of Nanning to provide a reference for the prevention and control of infectious diseases and construction and development of ICU in such a hospital.Methods The clinical data of inpatients from January 2011 to December 2015 in the Infectious Disease Hospital Affiliated to Guangxi Medical University (that is the Fourth People's Hospital of Nanning City) were retrospectively analyzed, and the distributions of patients with various diseases, ages, of the characteristics of children severe infectious diseases in ICU, the numbers of patients with infectious diseases in general ward and ICU, the average time and daily cost of hospitalization and mortality were conducted.Results During 2011 to 2015, 855 cases in ICU were treated, including 709 cases of infectious diseases, 146 cases of non-infectious disease. The top 5 infectious diseases were ranked as follows: tuberculosis, human acquired immune deficiency syndrome (AIDS), hand-foot-mouth disease (HFMD), viral hepatitis, tetanus, accounting for 96.47% of the total infectious disease inpatients in ICU; there were 25 cases of other legal infectious diseases, accounting for 3.53%, including dengue fever, measles, malaria, chicken pox, mumps, rabies, typhoid fever, paratyphoid fever, scrub typhus, bacillary dysentery, leptospirosis, human infections with highly pathogenic H7N9 avian influenza, epidemic hemorrhagic fever, A H1N1 influenza, and besides, critically ill patients carrying virus (viral hepatitis B and AIDS) in 7 pregnant women, 22 surgical patients, and 117 patients with internal medicine diseases were also admitted and treated. The top 4 infectious diseases causing deaths in ICU were tuberculosis, AIDS, viral hepatitis and HFMD: The infectious diseases with top 6 high mortalities in ICU were as follows: rabies, viral hepatitis, AIDS, tuberculosis and tetanus. The age range was wide in this study, from 73 days to 97 years, among which there were 167 cases of pediatric infectious diseases from pediatric department, accounting for 23.55% of ICU inpatients, being mainly severe HFMD, tuberculosis and severe varicella. From 2011 to 2015, the number of hospitalized patients showed a rising trend, and the average length of stay of patients in general wards presented a downward tendency, but the average time of hospitalization of inpatients with infectious disease in ICU, mortality and daily cost of hospitalization revealed a gradually increasing trend year by year.Conclusions It is of far-reaching significance to master the spectrum of dangerous severe infectious diseases to deal with the infectious disease epidemic situation and outburst with public health events.

Objective To investigate the expressions and relationship between lysine-specific demethylase 1 (LSD1) and E-cadherin protein in gastric cancer tissues and adjacent normal tissues,and the correlation with the clinicopathological features and prognosis of patients with gastric cancer.Methods The case-control study was adopted.The gastric cancer tissues and adjacent normal tissues were collected by surgical resection from 80 patients with gastric cancer who were admitted to the Xiangya Hospital of Central South University from June 2008 to June 2009.Expressions of LSD1 and E-cadherin protein were detected by immunohistochemistry (IHC).The follow-up of telephone interview was performed to detect survival of patients till June 2015.Relationships between the expressions of LSD1 and E-cadherin protein and clinicopathological features or prognosis of patients were analyzed.Comparison of count data and correlation were analyzed by the chi-square test and Spearman rank correlation analysis.Survival curve was drawn using the Kaplan-Meier method,and survival analysis was done using the Log-rank test.Results Expressions of LSD1 in cancer tissues and adjacent normal tissues were located at the cell nucleus.The positive expression rate of LSD1 was 67.5％ (54/80) and 43.8％ (35/80) in cancer tissues and adjacent normal tissues,respectively,with a significant difference (x2=9.141,P ＜ 0.05).Expressions of E-cadherin protein in cancer tissues and adjacent normal tissues were located at the cell membrane and cytoplasm.The positive expression rate of E-cadherin was 63.8％ (51/80) and 81.3％ (65/80) in cancer tissues and adjacent normal tissues,respectively,with a significant difference (x2 =6.140,P ＜ 0.05).The positive expression rate of LSD1 was 83.3％ (25/30),76.0％ (19/25) and 40.0％ (10/25) in the low-,moderate-and high-differentiated tumors,37.5％ (6/16),72.7％ (16/22),71.9％ (23/32) and 90.0％ (9/10) in the Ⅰ,Ⅱ,Ⅲ and Ⅳ stages of TNM stage,36.4％ (4/11) and 72.5 ％ (50/69) in patients without and with lymph node metastasis,respectively,showing significant differences (x2=12.870,9.425,4.111,P ＜ 0.05).The positive expression rate of E-cadherin protein was 53.3％ (16/30),56.0％ (14/25) and 84.0％ (21/25) in the low-,moderate-and high-differentiated tumors,75.0％ (12/16),63.6％ (14/22),71.9％ (23/32) and 20.0％ (2/10) in the Ⅰ,Ⅱ,Ⅲ and Ⅳ stages of TNM stage,100.0％ (11/11) and 58.0％ (40/69) in patients without and with lymph node metastasis,70.0％ (49/70) and 20.0％ (2/10) in patients without and with distant metastasis,respectively,showing significant differences (/x2 =6.494,10.073,5.547,7.426,P ＜ 0.05).There was a negative correlation in expressions between LSD1 and E-cadherin protein (r =-0.355,P ＜ 0.05).The survival time and 5-year overall survival rate of patients with positive and negative expressions of LSD1 were (36.9 ± 2.5) months and 31.1％,(47.4 ± 3.4) months and 56.0％,respectively,showing a significant difference (x2=4.550,P ＜0.05).The survival time and 5-year overall survival rate of the patients with positive and negative expressions of E-cadherin protein were (44.0 ± 2.5) months and 46.7％,(32.6 ± 3.5) months and 24.9％,respectively,showing a significant difference (x2 =7.306,P ＜ 0.05).Conclusions Positive expression of LSD1 in gastric cancer tissues is higher than that in adjacent normal tissues.There are increased expression of LSD1 and reduced expression of E-cadherin protein in low-differentiated gastric cancer tissues and high TNM stage,showing a negative correlation between them.Positive expression of LSD1 and negative expression of E-cadherin protein may indicate a poor prognosis.

A novel biosensor for aflatoxin B1 detecting has been reported. The biosensor electrode for AFB1 detecting was assembled by immobilized aflatoxin-oxidoreductase using open-ended multi-walled carbon nanotubes as matrix. Its linear range was between 0.16?M and 3.2?M. And if the specific anti-aflatoxin B1 antibody and aflatoxin oxidoreductase were both immobilized on the electrode with Multi-Walled carbon nanotubes, the detection limit of the modified electrode could be 16 nM with a 10 times improved sensitivity. The aflatoxin enzyme biosensor assembled this way strode one step forward its practical application.
