Objective To understand the epidemiological characteristics of central nervous system(CNS)infectious diseases in children hospitalized in capital institute of pediatrics.Methods All the 972 patients hospitalized in capital institute of pediatrics with the clinical diagnosis of CNS infectious diseases were analyzed from Jan.1997 to Dec.2006 retrospectively.The etiological detection of serum and/or cerebrospinal fluid(CSF)samples in acute stage collected from those patients included smear,cultivation and rapid etiological diagnosis of bacterium and fungus;determination of viral antibody,mycoplasma pneumonia antibody and tuberculous antibody.Results 1.A total of 972 patients were treated for CNS infectious diseases,accounting for 1.76% of inpatients of Internal Medicine at the same time.2.The main sources of CNS infectious diseases :747 cases of viral encephalitis,177 purulent meningitis,21 mycoplasmal encephalitis and 12 tuberculous meningitis.3.The ratio of male and female was 1.72:1.0 and the mean onset age was(4.75?4.03)years.4.Special infectious agents in serum and/or CSF samples were positive in 283(29.12%)cases.The total bacterial positive cases were 48/177 cases(27.12%).Streptococcus pneumonia(4.52%)was the most,followed by Escherichia coli(3.39%),Neisseria meningitides(3.39%)and Haemophilus influenzae B(Hib,3.39%).Viral antibodies were positive in 210/747 cases(28.11%).The major agents were herpes virus(HV)[128/747 cases(17.14%)]and enterovirus(EV)[91/747 cases(12.18%)].Conclusions CNS infectious diseases were important ones hospitalized in internal medicine of capital institute of pediatrics.Virus and bacterium were the main causes of CNS infectious diseases.Streptococcus pneumonia,Escherichia coli,Neisseria meningitides and Hib were the main agents of purulent meningitis.HV and EV were the main sources of viral encephalitis.

OBJECTIVE:To evaluate the economics of somatostatin,ulinastatin,octreotide and gabexate preventing hyperamy-lasemia and pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP). METHODS:Medical records of 316 cho-ledocholithiasis patients underwent ERCP were selected from our hospital during Jul. 2008-Apr. 2016,and then divided into blank control group(58 cases),somatostatin group(64 cases),ulinastatin group(65 cases),octreotide group(68 cases)and gabexate group (61 cases) according to the use of protease inhibitor. Before ERCP,blank control group received routine treatment as fast-ing,parenteral nutrition support,acid suppression,etc. Based on it,other 4 drug groups received prophylactic drug use according to package inserts 6 h before ERCP. The incidence of hyperamylasemia and pancreatitis after ERCP,VAS scores 3,24,48 h after surgery and the occurrence of ADR were compared among 5 groups. The cost-effectiveness analysis was used to evaluate the eco-nomics of therapy plans in each group. RESULTS:Compared with blank control group,hospitalization time of somatostatin group, ulinastatin group,octreotide group and gabexate group were shortened significantly;the incidence of hyperamylasemia and pancre-atitis were significantly decreased;VAS score 3,24,48 h after surgery were significantly decreased,with statistical significance (P<0.05). Compared among 4 groups,above indexes had no significant difference,and the incidence of ADR was in low level and had no statistical significance(P>0.05). The cost-effectiveness ratio of somatostatin group was the lowest and has cost-effec-tiveness advantage. The results were supported by incremental cost-effectiveness and sensitivity analysis. CONCLUSIONS:Soma-tostatin,ulinastatin,octreotide and gabexate can significantly prevent the occurrence of hyperamylasemia and pancreatitis after ER-CP,and relieve pain with good safety. Somatostatin can achieve the best therapeutic efficacy at the lowest cost,so it is the best plan for hyperamylasemia and pancreatitis after ERCP.

Objective To investigate the incidence of osteoporosis (OP) in patients with ankylosing spondylitis and the relationship between OP and the clinical data. Methods Serum levels of bone alkaline phosphatase (BALP) and tartrate resistant acid phosphatase 5b (TRACP5b) were detected by enzyme linked immunosorbent assay ( ELISA ) in 60 cases with ankylosing spondylitis, and it was compared with normal controls. Bone mineral density (BMD) was measured through dual-energy X-ray absorptiometry ( DXA), including lumbar ( L2 - L4), bilateral femoral neck and greater trochanter. Some clinical data was collected and analyzed at the same time. Results The incidence of OP in AS patients was 35%, and the incidence of OP in the femoral proximal end was higher than that in lumbar. Compared with normal controls[ ( 1.06 ±0. 18 )U/L ], the levels of serum TRACP5b in AS[ (1.31 ± 0. 82 )U/L] patients was significantly higher ( P <0. 05 ). The levels of serum BLAP in OP combined AS group[ ( 21.65 ± 5.41 ) U/L]were significantly lower than non-OP group[ (32. 37 ± 16. 5 ) U/L] ( P <0. 05 ). The disease duration was negatively correlated with the BMD of femoral neck ( P < 0. 01 ). Conclusions There was higher incidence of OP in AS patients, which were related with the abnormality of bone metabolism and the disease duration.Multiple factors participated in the regulation of bone metabolism of AS.

Objective To determine the effect of bacille Calmette-Guerin-polysaccharide nucleic acid (BCG/PSN)on 2,4-dinitrochlorobenzene(DNCB)-induced atopic dermatitis-like skin lesions in Nc/Nga mice.Methods Fifteen mice were randomly and equally classified into 3 groups,i.e.,control group receiving topical acetone on foot pad and abdomen and intraperitoneal injection of physiological saline,model group receiving topical 5% DNCB solution and intraperitoneal injection of physiological saline,treatment group receiving 5% DNCB solution and intraperitoneal iniection of BCG/PSN,and all drugs were used every other day for 7 weeks.Further more,0.1% DNCB was topically applied on the ear and neck of Nc/Nga mice once a week from week 2 to week 7.The effects of BCG/PSN were evaluated by ear thickness,skin histopathology and immunological parameters.Results Repeated application of DNCB caused the development of eczematous dermatitis in mice.Mice in model group chnieally manifested skin dryness,erythema,edema and erosion with histopathological changes including dermal and epidermal thickening,hyperkeratosis,and inflammatory infiltration.The serum levels of IL-4 and IrE in model group were significantly higher than those in control group[(174.72±12.64)μg/L vs (17.32±3.56)μg/L,(91.49±6.32)ng/L vs (83.95±6.63)ng/L,both P<0.05].Increased serum IL-12 and IFN-γ and decreased serum IgE were observed in treatment group compared with the model group[(122.10±4.64)ng/L vs (20.14±6.15)ng/L(73.89±2.39)ng/L vs (51.53±3.45)ng/L, (84.27±9.35)μg/L vs (174.72±12.64)μg/L, all P<0.05].Conclusion BCG/PSN might be beneficial for the treatment of atopie dermatitis-like skin lesions in Nc/Nga mice by enhancing the secretion of IL-12 and IFN-γ and suppressing the synthesis of IgE.

Objective:To study the in vitro and in vivo transdermal enhancement of one kind of arginine oligomer-chitosan ( CS-R9). Methods: In vitro mouse skin as the barrier, Franz diffusion cells were used to study the transdermal property of tinidazole ( TNZ) solution in vitro enhanced by CS-R9 using TNZ solution as the negative control and TNZ solution with Azone as the positive control. The rats were randomly divided into three groups, TNZ solution group ( the negative group) , TNZ solution with Azone group (the positive group) and TNZ solution with CS-R9 group. At the predetermined time intervals, 0. 5 ml blood was withdrawn from the rats and TNZ concentration was detected by HPLC to evaluate the enhancement of CS-R9 on TNZ in vivo. Results:Compared with the negative group, CS-R9 had significant enhancement on TNZ trandermal penetration in vitro(P <0.05), and showed no significant difference with Azone (P>0. 05). The in vivo results showed CS-R9 exhibited similar transdermal enhancement on TNZ as Azone at the same concentration (P>0. 05), and CS-R9 had sustalned-release property. Conclusion: CS-R9 has promising transdermal en-hancement on TNZ, which is valuable to be studied further.
