Objective To acknowledge the spouse comorbid conditions of diabetes patients by comparing the average blood sugar level of the spouse of the diabetes patients with normal Guangzhou residents.Methods To sift and analyze the spouse test results of 152 hospitalized diabetes patients from January 2012 to January 2013,by testing the blood sugar level of the experimental subjects,comparing the different blood sugar level results between when they were with empty stomach and 2 hours after oral glucose tolerance test (OGTT).Results There were 32 cases with diabetes,9 cases with impaired glucose tolerance (IGT) and 11 cases with impaired fasting glucose (IFG) in the above 152 experimental subjects.The morbidity rates were 21.05％,5.92％ and 7.24％.All the above results were higher than the Guangzhou residents survey level,there were statistical differences between them.Conclusions The high morbidity rates of diabetes and impaired glucose regulation in diabetes patients spouse are obvious.The works for diabetes sifting and analyzing together with the health education instruction need to be strengthened.

Objective To understand the enterovirus infection in family close contacts of patients with hand,foot and mouth disease (HFMD) and the contamination of environment.Methods Forty-one HFMD cases confirmed by laboratory from web-based surveillance system during July to August 2010 in Guangdong Province were selected.All members of the cases′ family were investigated by collecting their information on demography,habit of domestic hygiene and hygiene status in household.The stool samples of all members and the smear samples from the surface of family belongings from 16 families were collected and the enterovirus was detected by real time quantitative polymerase chain reaction.The data were analyzed by chi square teat and t test.ResultsForty-one HFMD cases′ families and 135 close contacts were included in this survey.The infection rate of the enterovirus was 39.2％ (53/135) in all close contacts.Of all the investigated families,the infectionrate was 58.5％ (24/41) in family with one or more close contacts and 9.8％ (4/41) in family with all close contacts.The differences of infection rates of enterovirus among the members of parents (32.5％,25/77),grandparents/aunts/ uncles (43.3％,13/30) and cousins (53.6％,15/28) didn′t show statistical significance (χ2 =4.07,P=0.131).The infection rate of enterovirus in close contacts from family with more than 5 members was higher than that from family with 4 or less members (OR=1.4,95％CI 1.1-1.9).Among 135 close contacts,27.4％ (37/135) were infected with the same types of entervirus as that of HFMD case in the family and 11.9％ (16/135) were infected with the different virus types.In 33 family belongings samples from 16 families,the positive rate of enterovirus detection was 6.1％ (2/33).Between 17 families with enterovirus testing negative and 23 families with enterovirus testing positive in close contacts,there were no statistical differences of the family hygiene status,hand-washing of babysitter,disinfection of tableware and drinking,sharing towels,airing bedding articles and toy cleaning (P＞0.05).ConclusionsThe infection rate of enterovirus in close contacts of HFMD cases is high and the enterovirus contamination exists in case family environment.Management of close contacts of HFMD cases and disinfection of the family environment are important in HFMD controls.

Important/potential value of macrolides has been proved in the management of chronic respiratory diseases by increasing basic and clinical trials.Through three face-to-face discussions,10 experts examined important data and drafted this consensus related to macrolides:(1) mechanism of nonantiinfective effects;(2) clinical use in chronic respiratory diseases;(3) cautions of long-term use.The mechanism out of non-antiinfective effects includes anti-inflammatory effect,modifying airway secretion,immune-regulation related to antibacterial effect,corticoid saving effect and anti-viral effect.The efficacy of long-term use of low-dose macrolides is definitely confirmed in diffuse panbronchiolitis,chronic rhinosinusitis.It is considerably used in bronchiectasia,cystic fibrosis,severe asthma and chronic obstructive pulmonary disease.Further studies should be conducted in cryptogenic organizing pneumonia and respiratory viral infection.It should be paid attention to its possible adverse effects (including drug interactions,cardiac toxicity,ototoxicity and disturbance of intestinal flora) and drug resistance in long-term use.A Chinese consensus for non-antiinfective effects and clinical use of macrolides is developed for the first time,which aims to expand their rational use and the further research.

PURPOSE: Asthma affects approximately 30 million patients in China; however, tiotropium data for Chinese patients is limited. This study aimed to assess the efficacy and safety of tiotropium in Chinese patients with moderate symptomatic asthma. METHODS: A post hoc subgroup analysis was conducted on 430 Chinese patients pooled from two 24-week, replicate phase 3 trials (NCT01172808 and NCT01172821), in which they received once-daily tiotropium 2.5 µg (Tio R2.5) or 5 µg (Tio R5) (n = 106 or 109, respectively), twice-daily salmeterol 50 µg (Sal 50) (n = 110), or placebo (n = 105), while maintaining inhaled corticosteroids (ICS). The co-primary endpoints assessed in week 24 were forced expiratory volume in 1 second (FEV1) peak0–3h response, trough FEV1 response, and responder rate as assessed using the Asthma Control Questionnaire (ACQ). RESULTS: For both FEV1 peak0–3h responses and trough FEV1 responses, the mean treatment differences were greater for Tio R2.5, Tio R5, and Sal 50 compared with placebo at 0.249 L, 0.234 L, and 0.284 L, and 0.172 L, 0.180 L, and 0.164 L, respectively (P< 0.001). The ACQ responder rate in placebo, Tio R2.5, Tio R5, and Sal 50 was 58.7%, 62.3%, 59.3%, and 69.1%, respectively. Furthermore, 11 (2.6%) of 430 patients had serious adverse events (Tio R5, n = 4; Tio R2.5, n = 1; Sal 50, n = 1; and placebo, n = 5). CONCLUSIONS: Once-daily tiotropium, as add-on to medium-dose ICS, was effective and well tolerated for Chinese patients with moderate symptomatic asthma, consistent with the main analysis.

Objective:To analyze the laboratory test results of two outbreaks of neonatal enterovirus infections in Guangdong Province in 2019 and the genetic characteristics of Echo11, aiming to provide reference for the prevention and control of neonatal enterovirus infections.Methods:The pathogenic specimens of neonatal cases suspected of enterovirus infection were collected. Fluorescence quantitative PCR and sequencing were used for enterovirus typing and identification, and virus isolation was carried out for positive specimens.The complete sequences of VP1 of Echo11 were amplified and sequenced and the phylogenetic analysis was performed using the bioinformatics software such as Danstar6, Bioedit7.09 and MEGA6.06.Results:A total of 93 specimens from 36 neonatal cases were collected. After identification, 55 specimens from 24 cases were positive for enterovirus, of which 23 cases were positive for Echo11 and one case was positive for Coxsackievirus B4(CVB4). A total of 29 enterovirus strains were isolated from the specimens of 19 cases, of which 28 were Echo11 from 18 cases, and one was CVB4. Phylogenetic analysis revealed that the nucleotide homology between the 18 strains of Echo11 in this study was 98.2%-100.0%, and the nucleotide homology between the Echo11 strains causing the two neonatal infections was 99.7%-100.0% and 99.8%-100.0%, respectively. Echo11 could be divided into six genotypes as A, B, C, D, E and F, in which genotype A and genotype C were further divided into A1-5 and C1-4, and genotype D could be divided into D1-5. The 18 strains of Echo11 in this study were all subtype D5.Conclusions:In 2019, two outbreaks of neonatal infections in medical institutions in Guangdong Province were caused by Echo11, which belonged to the genotype D5.

Objective To study the relationship between bronchial asthma and smoking status in Chinese people.Methods Asthma epidemiological survey and stratified-cluster-random method survey were performed in residents over 14 years in 8 provinces (cities) of China from February 2010 to August 2012.Asthma was diagnosed based upon case history,clinical signs and lung function test.Smoking status was investigated by questionnaire.Results Sampling population was 180 099 and 164 215 were valid.A total of 2 034 subjects were diagnosed as asthma including 79 692 men and 84 523 women.The overall prevalence rate of asthma was 1.24％ (2 034/164 215).Smokers were 23.8％ (39 137/164 215) in the whole population.Smokers were 34.5％ (702/2 034) in asthmatic patients,compared with 23.7％ (38 435/ 162 181) in no-asthmatic population.The incidence of asthma was 1.79％ and 1.06％ in smokers and nonsmokers respectively (P ＜0.001),suggesting that OR of smoking was 1.70 (95％ CI 1.55-1.86,P ＜ 0.001).According to asthma control test (ACT) score,the level of asthma control in non smoking group was higher than that in smoking group(43.2％ vs 35.3％).The times of hospitalization due to acute exacerbations (0.51 vs 0.41 events/person/year),total hospitalization rate (27.35 ％ vs 20.12％),annual emergency room visits (0.80 vs 0.60 events/person/year) and emergency room visit rate (31.77％ vs 24.47％) were all much higher in smoking asthmatic patients than those in non smoking asthmatic patients,indicating that the level of asthma control in smoking patients was significantly worse than in non smoking patients.Conclusions The smoking rate in Chinese people over 14 years is still high.The prevalence rate of asthma in smokers is significantly higher than that of non-smokers.The level of asthma control in smokers is significantly worse than that in non smokers.

Objective To provide scientific evidence to identify and confirm severe acute respiratory syndrome (SARS) by laboratory detection.Methods Multiple clinical specimens were collected serially and systematically from the 4 suspected SARS patients, which occurred between Dec.2003 to Jan.2004 in Guangdong Province. The samples were tested by serologic and molecular methods.Results IgM or IgG antibodies against SARS-CoV were detectable after 6—8 days of the onset in four patients. The four-fold or greater rising in antibodies was clearly detected in three of the four patients, while the fourth patient’s seroconversion was from negative to positive. The results analysed by enzyme-linked immunosorbent assay( ELISA), immunoflourescence assay (IFA), and neutralization test were highly correlated. SARS-CoV RNA was just detected in 3 throat swab specimens from case 1 by real-time PCR. M, N and S genes were amplified by reverse transcriptase polymerase chain reaction (RT-PCR) from the positive samples. Sequencing results showed that they were SARS-CoV gene segments, and most closely matched SARS-CoV gene sequences were isolated from civet cats in Guangdong Province. Nevertheless, SARS-CoV was not isolated from any samples of the 4 patients.Conclusion Based on these results, the 4 reported cases were laboratorily confirmed as SARS cases.
