Objective: To investigate the effect of space glucose control (SGC) on the quality of blood glucose management in ICU patients with stress hyperglycemia. Methods: A prospective, cross-controlled, quasi-trial was conducted to observe patients with ICU-induced stress hyperglycemia between January 2018 and January 2019. Patients with conventional blood glucose management served as the control group, and SGC blood glucose management was used as the intervention group. The enrolled patients were interchanged between the two groups every 24 h, and the end point was 96 h. The differences in blood glucose management quality indicators between the two groups were compared, including the average blood glucose level, the highest and lowest blood glucose level, the average blood glucose monitoring interval, and the accumulated insulin dosage. SPSS 23.0 was used to analyze the data. The paired t test was used for the normal distributed data. Otherwise, two nonparametric correlation sample tests was used. A P<0.05 was considered statistically significant. Results: A total of 41 patients enrolled in this study during the study period. The average blood glucose value in the intervention group was significantly lower than that in the control group [(8.60 ±1.42)mmol/L vs (10.02 ±1.49)mmol/L, P< 0.01]. The frequency of hyperglycemia was lower than that of the control group (16.59 ±8.56 vs 18.73 ±7.91, P=0.023). The frequency of blood glucose value in the target blood glucose range was significantly higher than that of the control group (53.07±19.11 vs 29.44±19.60, P< 0.01). However, the frequency of hypoglycemia, the frequency of blood glucose monitoring and the accumulated insulin dosage in the intervention group were higher than those in the control group [1 (0, 5) vs 0 (0, 2), P< 0 01; 1 36 ±0 23 vs 1 89 ±0 28, P< 0.01; and (139.61 ±77.06)U vs (107.49 ±64.41)U, P<0.01]. Conclusions SGC can optimize the control of blood glucose in the target blood glucose range, but it can easily lead to mild hypoglycemia, and to a certain extent increases the workload of medical staff.

OBJECTIVETo study the severe acute respiratory syndrome (SARS)-associated coronavirus genotype and its characteristics.

METHODSA SARS-associated coronavirus isolate named ZJ01 was obtained from throat swab samples taken from a patient in Hangzhou, Zhejing province. The complete genome sequence of ZJ01 consisted of 29,715 bp (GenBank accession: AY297028, version: gi: 30910859). Seventeen SARS-associated coronavirus genome sequences in GenBank were compared to analyze the common sequence variations and the probability of co-occurrence of multiple polymorphisms or mutations. Phylogenetic analysis of those sequences was done.

RESULTSBy bioinformatics processing and analysis, the 5 loci nucleotides at ZJ01 genome were found being T, T, G, T and T, respectively. Compared with other SARS-associated coronavirus genomes in the GenBank database, an A/G mutation was detected besides the other 4 mutation loci (C:G:C:C/T:T:T:T) involved in this genetic signature. Therefore a new definition was put forward according to the 5 mutation loci. SARS-associated coronavirus strains would be grouped into two genotypes (C:G:A:C:C/T:T:G:T:T), and abbreviated as SARS coronavirus C genotype and T genotype. On the basis of this new definition, the ZJ01 isolate belongs to SARS-associated coronavirus T genotype, first discovered and reported in mainland China. Phylogenetic analysis of the spike protein gene fragments of these SARS-associated coronavirus strains showed that the GZ01 isolate was phylogenetically distinct from other isolates, and compared with groups F1 and F2 of the T genotype, the isolates of BJ01 and CUHK-W1 were more closely related to the GZ01 isolate. It was interesting to find that two (A/G and C/T) of the five mutation loci occurred in the spike protein gene, which caused changes of Asp to Gly and Thr to Ile in the protein, respectively.

CONCLUSIONAttention should be paid to whether these genotype and mutation patterns are related to the virus's biological activities,epidemic characteristics and host clinical symptoms.

In this study,the current status for breast diseases in a region with high-incidence of cervical cancer were epidemiologically investigated.From March to August,2009,17618 women,from Wufeng area of Hubei province,China,were recruited to screen breast diseases by using breast infrared diagnostic apparatus.Other diagnostic methods,such as B-mode ultrasound,X-ray mammography,needle biopsy and pathological examination were,if necessary,used to further confirm the diagnosis.The screening showed that 5990 of 17618 cases (34.00％) had breast diseases,5843 (33.16％) had mammary gland hyperplasia,48 (0.27％) had breast fibroadenoma,ll (0.06％) had breast carcinoma,and 88 (0.50％) had other breast diseases.The peak morbidity of breast cancer was found in the women aged 50-0 ages.The morbidity of breast cancer was significantly increased in women elder than or equal to 50 years old (n=8,0.157％) in comparison with that in the subjects younger than 50 years old (n=3,0.024％) (u=2.327,P＜0.05).It was shown that the occurrence of breast diseases was concentrated in women aged 20-40 years,while the total morbidity reached its peak at the age of 30 years and then decreased sharply after age of 40.Compared with the patients elder than or equal to 40 years old (n=3289,27.46％),the morbidity rate of breast diseases was significantly increased in women less than 40 years old (2648 cases,47.18％; P＜0.001).However,there was no significant difference in the morbidity of breast diseases between the age group of 20-29 years and that of 30-39 years (P=0.453),and both of them were high.There was no significant association between the morbidity of breast diseases and cervical cancer.Since the morbidity of breast diseases was higher among young women,more attention should be paid to the screening of breast diseases among young women for early diagnosis.
