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 investigate the value of detecting BK virus(BKV)in urine of renal al- lograft recipients for the diagnosis and treatment of BKV infection.Methods Using polymerase chain re- action(PCR)method combined with DNA sequencing,61 urine samples from renal allograft recipients,30 u- fine samples from dialytic patients and 30 urine samples from healthy volunteers(controls)were detected. The results were compared among the 3 groups.Results The BKV positive rate in renal allograft recipi- ents was 36.1%,compared with 13.3% in dialytic patients(P＜0.05)and 0.0% in controls(P＜0.05). One renal allograft recipient who was positive for BKV developed ureteral obstruction.The BKV positive rate was 40.9%(9/22)in renal allograft recipients with rejection episode,compared with 33.3%(13/39)in the recipients without rejection episode(P＞0.05);and the BKV positive rate was 36.0%(18/50)in the recip- ients with normal graft function,compared with 36.4%(4/11)in the recipients with abnormal graft function (P＞0.05).Conclusions Renal allograft recipients are the high risk population who may develop BKV viruria.There is no correlation between recipients with or without rejection episode and BKV viruria,and also no correlation between recipients with normal or abnormal graft function and BKV viruria.Detection of BKV in the urine of renal allograft recipients is helpful in differential diagnosis of BKV induced ureteral obstruc- tion,and PCR method for detecting BKV DNA can be used to screen for BK virus-associated nephropathy (BKVAN).

Objective To explore the clinical significance and changes of tumor necrosis factor-?(TNF-?)and interleukin-6(IL-6)level in children with acute viral myocarditis(AVM).Methods TNF-? and IL-6 level in serum from 53 AVM children and 20 healthy children were measured by radio-immunoassay and enzyme-linked immunosorbent assay(ELISA).The relation between the levels of TNF-? and IL-6 in serum with the occurrence and development in acute viral myocarditis was analyzed.Results Thirty-two were males and 21 females in the 53 AVM children.The ages ranged from 3-11 years old.There were 12 males and 8 females in control group.The serum level of TNF-? and IL-6 were(526.7?32.9),(3.23?0.53)mg/L in AVM group and(383.1?27.5),(1.63?0.22)mg/L in control group.There were significant difference between the 2 groups(Pa

Objective To study the clinical therapeutic effect of acupuncture in the treatment of depressive neurosis.Methods The 60 selected patients of depressive neurosis were randomized into treatment group(acupuncture regulating the liver group)and con- trol group(near-by sham-point acupuncture group),with 30 in each.The scores of Symptom Checklist 90(SCL-90),Self-rating De- pression Scale(SDS),and Hamilton Depression Scale(HAMD),and the total effective rate after treatment were observed.Results The total effective rate of the treatment group and the control group was 92.6% and 56.0% respectively,and the difference was sig- nificant(P

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.

The experience of Professor LI Zhidao is introduced in the treatment of mental disorders by "regulating the heart and smoothing the liver". In his experience, the basic prescription includes: penetrating needling technique from Neiguan (PC 6) to Jianshi (PC 5), Ximen (PC 4), penetrating needling technique from Qiuxu (GB 40) to Zhaohai (KI 6) and penetrating needling technique at four groups of acupoints on the gallbladder meridian [Hanyan (GB 4) to Xuanlu (GB 5) and Xuanli (GB 6), Qubin (GB 7) to Shuaigu (GB 8), Shuaigu (GB 8) to Tianchong (GB 9), Tianchong (GB 9) to Fubai (GB 10) and Touqiaoyin (GB 11)]. The manipulation with respiration involved is combined with interactive needling technique so that the patients can feel the weak needling sensation at the local acupoint regions during the treatment. In the paper, the concrete clinical cases are introduced to explain this application and the satisfactory efficacy achieved. The therapeutic method provides a new approach to the clinical treatment of mental disorders.
