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.
2.Atherosclerosis occurs in patients undergoing maintenance hemodialysis
Chinese Journal of Tissue Engineering Research 2013;(31):5666-5672
BACKGROUND:Atherosclerosis is a common complication in diabetic nephropathy and hemodialysis patients. The effect of hemodialysis duration and other relative factors on the atherosclerosis of patients with diabetic nephropathy needs to be further observed and explored. OBJECTIVE:To observe the atherosclerosis in the patients with different hemodialysis durations, then to evaluate the effect of hemodialysis duration and other relative factors on atherosclerosis of patients with diabetic nephropathy. METHODS:The intima-media thickness of the carotid artery in the diabetic nephropathy hemodialysis group, non-diabetic nephropathy hemodialysis group and end-stage renal disease non-hemodialysis group was detected with high-frequency ultrasonic testing, and the healthy volunteers were as the normal control group. The relationship between the intima-media thickness of the carotid artery in the hemodialysis patients and hemodialysis duration was analyzed, and the changes of insulin resistance in each group were compared. RESULTS AND CONCLUSION:Compared with the normal control group, the intima-media thickness of the carotid artery in the diabetic nephropathy hemodialysis group and non-diabetic nephropathy hemodialysis group was increased (P<0.01);there was no significant difference of intima-media thickness of the carotid artery between 24 hours diabetic nephropathy hemodialysis group and end-stage renal disease non-hemodialysis group (P>0.05);the intima-media thickness of the carotid artery in the 60 months diabetic nephropathy hemodialysis group was higher than that in the 24 hours diabetic nephropathy hemodialysis group (P<0.05);the intima-media thickness of the carotid artery in the 60 months diabetic nephropathy hemodialysis group was significantly higher than that in the end-stage renal disease non-hemodialysis group (P<0.01). There was no significant difference of intima-media thickness of the carotid artery between 60 months diabetic nephropathy hemodialysis group, end-stage renal disease non-hemodialysis group and 24 hours diabetic nephropathy hemodialysis group (P>0.05). The homeostasis model of assessment-insulin resistance value in the 24 hours diabetic nephropathy hemodialysis group was slightly lower than that in the diabetic nephropathy non-emodialysis group (P<0.05), and the homeostasis model of assessment-insulin resistance value in the 60 months diabetic nephropathy hemodialysis group was significantly lower than that in the diabetic nephropathy non-emodialysis group (P<0.01). The development of atherosclerosis on diabetic nephropathy patients can be affected by hemodialysis to some extent. And the effect is correlated with the hemodialysis duration.

4.Quality control of flow cytometric immunophenotyping
Chinese Journal of Laboratory Medicine 2011;34(5):389-394
Flow cytometric immunophenotyping has evolved from two-parameter quantitative measurement of peripheral blood lymphocytes to five-or more parameter qualitative evaluation of bone marrow and lymph node in hematopathology.Leukemia/lymphoma immunophenotyping represents an important addition to histomorphology in the diagnosis,classification and monitoring of hematolymphoid neoplasms.The complexity of five-or more parameter analyses and the interpretation of the data rely on standardization and validation of the instrument,the reagent and the procedure.In addition,clinical flow cytometry laboratories in U.S.A are required to document proficiency testing,sample preparation as well as accuracy,specificity,sensitivity and precision of methodology.CLSI and UCCC recommend that each laboratory should validate its own qualitative and quantitative procedures.This paper introduces the procedures for validation and quality control in a clinical flow cytometry laboratory in the United States.

China Pharmacy 2017;28(23):3254-3257
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.
