Objective To construct markless gene deletion mutant at the clpP loci on the chromosome of Streptococcus mutans(S.mutans).Methods ASp resistance gene was amplified by PCR,to construct the Sp resistance cassette where the Sp resistance gene was flanked with two loxP site.After the clpP gene was cloned into the pGEM-T-Easy TA cloning vector,it was digested and linked with the Sp resistance cassette,yielding homologous recombination vector pIB △ clpP-Sp.The vector was linearized and used for the transformation of S.mutans UA159,with transformants selected on TPY plates containing Sp.The selected strain was transformed with the thermosensitive plasmid pCrePA to excise the Sp resistance gene.The pCre-PA was then easily eliminated at nonpermissive temperature,resulting in a markless mutant strain carrying a deletion at the clpP loci,which was verified by PCR and DNA sequencing.Results The result of the PCR analysis and DNA sequencing indicated that a part of the clpP gene was deleted.There was a loxP at this loci without the Sp resistance gene.Conclusion The markless clpP-deletion mutant of S.mutans was constructed successfully,which laid a foundation for further study of its biological function and its influence on the cariogenicity of S.mutans.

Objective To study the influence of different dialysis frequence on infection and prognosis of maintenance hemedialysis patients. Methods Fifty-three maintenance hemodialysis patients with chronic kidney disease were divided into 3 groups. Groups A, B, C dialysed thrice per week (19 cases),twice per week (15 cases) and thrice per two weeks (19 cases), respectively. All the patients were dialysed for 1 year. The rate of infection, death number and death reason were recorded. Results All the cases were infected 62 times (17 times in group A, 18 times in group B and 27 times in group C). Pulmonary infection,blood vessels infection, urinary tract infection and digestive tract infection happened 35 times(56.45% ), 14 times (22.58%), 8 times (12.90%) and 5 times (8.06%) respectively. Eight cases died in three groups,and the total death rate was 15.09%, with 1 case in group A,1 case in group B and 6 cases in group C.There was significant difference in prognosis among three groups (χ2 =6.293,P <0.05). Conclusions Patients who dialysis less than twice per week have higher rate of infection and death. Dialysis program should be adjusted and dialysis frequence should be increased.

Objective:To observe the role of Huaiqihuang Granules (HQ) in the long-term management of bronchial asthma in young children, and the effective effect on concomitant rhinitis.Methods:A prospective real-world multicenter study was conducted in children aged 2-5 years with asthma diagnosed in the outpatient department (from April 2016 to March 2019)who received either inhaled corticosteroid (ICS)/leukotriene receptor antagonist (LTRA)(control group); inhaled ICS/LTRA plus HQ(combination group), or HQ alone(HQ group). All patients were followed up at week 4, 8, 12 after treatment. The number of days with asthma symptoms, the frequency of severe asthma attacks, the level of asthma control, and the days with rhinitis symptoms in the last 4 weeks were recorded. Differences before and after treatment, and those among groups after treatment were compared using Kruskal- Wallis H test or Wilcoxon rank-sum test. Results:A total of 2 234 eligible patients were recruited, and 2 147 cases completed followed-up visits, including 477, 1 374 and 296 cases in the control group, combination group, and HQ group, respectively. After the treatment, all 3 groups showed significant declines in the days with asthma symptoms, frequency of severe asthma attack and the days with rhinitis symptoms (all P<0.01), and the rate of well-controlled asthma increased significantly ( P<0.01). It lasted until the end of follow-up. Among groups, patients in the combination group showed significantly less days of asthma symptoms than those of the other 2 group at week 8 and 12[0(0, 0.9) d vs.0(0, 0.3) d, P<0.05; 0(0, 0.1) d vs. 0(0, 1.0) d, P<0.01]. Patients in the combination group and HQ group showed a significantly lower rate of severe asthma attacks than that of the control group at week 12 [0(0, 1), 0(0, 1), 0(0, 2), all P<0.05]. The well-controlled rate of asthma in the combination group was significantly higher than that of the control group and HQ group at week 8 and 12 (89.6% vs. 85.9% vs.82.1%, H=15.28; 90.9% vs. 84.1% vs. 81.8%, χ2=29.32, all P<0.01). Conclusions:HQ can significantly alleviate symptoms of asthma and rhinitis, severe attack of asthma, and increase the control rate of asthma when used as an additional treatment or used alone.

ObjectiveTo understand the experience, knowledge and attitudes of e-cigarette users in Shanghai, and to provide evidence for the development of intervention programs for e-cigarette use. MethodsThe Respondent-Driven Sampling (RDS) method was used to recruit 40 e-cigarette users for qualitative interviews from November 2020 to February 2021. NVivo (11.0) software was used to code interview records, and the thematic pattern and relationship analysis were conducted. ResultsIn terms of the reasons and user experience of e-cigarette use, most respondents used e-cigarettes for the first time after recommendation of friends; The reasons for the current use of e-cigarettes focus on the subjective feelings generated by the use of e-cigarettes (easy to use, replacing traditional tobacco, and having many flavors). Compared with traditional tobacco use, respondents said e-cigarettes tasted good and had no physical impact (they could be used all the time without making them uncomfortable). In terms of the awareness of e-cigarette use related knowledge, the respondents' opinions on whether e-cigarettes caused health risks were mostly based on their own experience of using them, and they said it was difficult to identify real information online. As for whether they were interested in relevant knowledge, most respondents said they wanted to learn about the professional knowledge related to e-cigarettes. Regarding the attitude related to the use of e-cigarettes, most respondents believed that e-cigarettes are addictive, e-cigarettes are not a safe alternative to traditional tobacco, ande-cigarettes couldn't help them quit smoking. Three out of ten respondents said they supported including e-cigarettes in the Regulation on Smoking Control in Public. ConclusionThere are certain characteristics of e-cigarette users' feelings, related knowledge and attitude towards e-cigarette use that should be targeted to carry out publicity, education and intervention.
