1.Progresses in epidemiology, diagnosis and treatment of childhood human metapneumovirus infection
International Journal of Pediatrics 2010;37(5):542-545
Human metapneumovirus (HMPV)is a recently discovered virus associated with respiratory tract infection. Most infections with HMPV occurred during winter and spring. Children, elderly subjects and immunosuppressed hostsare susceptible. The consequences of HMPV infections ranged from mild upper respiratory tract infection to severe bronchiolitis or pneumonia. There are three different kinds of methods for the diagnosis of HMPV infections, detection of virus antigen-antibody, virus isolation by culture, and RNA detection by reverse transcription-PCR. Symptomatic therapy is the main method of treatment.

OBJECTIVE:To investigate the effects of minocycline on clinical indexes,inflammatory factors and blood glucose of patients with moderate and severe chronic periodontitis complicated with type 2 diabetes(T2DM). METHODS:A total of 125 patients with moderate and severe chronic periodontitis complicated with T2DM selected from our hospital during Feb. 2013-Aug. 2015 were divided into control group(63 cases)and observation group(62 cases)according to random number table. Both groups were periodental non-surgical treatment as scaling and root planning. Control group was given iodine glycerin to fill periodontal pockets after surgery,2-4 times/d. Observation group was given Minocycline hydrochloride ointment,once a week,after surgery. Both groups were treated for 4 weeks. The levels of clinical indexes [probing depth,clinical attachment level(CAL),probing bleeding rate],serum inflammatory factors(CRP,TNF-α)and blood glucose(fasting blood glucose,glycosylated hemoglobin) were observed in 2 groups before treatment,3 months after treatment,and the occurrence of ADR was recorded. RESULTS:Be-fore treatment,there was no statistical significance in clinical indexes,serum inflammatory factors and blood glucose levels be-tween 2 groups(P>0.05). Three months after treatment,probing depth,probing bleeding rate and serum inflammatory factor lev-els of 2 groups were decreased significantly,and the observation group was significantly lower than the control group,with statisti-cal significance(P<0.05). Compared to before treatment,CAL of 2 groups were increased,without statistical significance before and after treatment or between 2 groups(P>0.05). The levels of fasting blood glucose in 2 groups were decreased,with statistical significance(P<0.05),but no statistical significance between 2 groups(P>0.05). Compared to before treatment,the level of glycosylated hemoglobin in control group was decreased,without statistical significance(P>0.05);the level of glycosylated hemo-globin in observation group was decreased significantly,and the observation group was significantly lower than the control group, with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between observation group (3.23%) and control group (0)(P>0.05). CONCLUSIONS:For moderate and severe chronic periodontitis complicated with T2DM,minocycline effectively improves clinical indexes of periodontitis,reduces serum inflammatory factors and blood glucose with good safety.
