OBJECTIVE To investigate the application of antibacterials in patients accepted operation in grass-roots(hospitals),so to standardize the application of antibacterials and cut down the medical cost.METHODS Full-time administrators for nosocomial infection investigated the application of antibacterials in patients who accepted(operation) in Sep 2004,and filled in the questionnaires.RESULTS In 1 383 cases of 11 hospitals the application rate of antibacterials was 98.63%;in which 86.50% were for prophylactic usage and 13.50% for therapeutic usage;(29.90%) for single antibiotics treatment and 50.15% for bigeminy,18.70% were for trigeminy.Time of(application) differentiated(6.90,7.00,6.60d) fromⅠto Ⅲ kinds of operation.Per capita cost of antibacterials was $956.50(47.60%).CONCLUSIONS High cost of antibacterials results from such factors as multiple kinds,long time and(combined) application.

OBJECTIVE:To investigate the preparation technic and method of quality control of Xinyoukexing tincture(XYKX) METHODS:To determine the content of Valaciclovir by spectrophotography,and podophyllotoxin by dual-wavelength spectrophotography RESULTS:In the range of 14 88～34 72?g/ml,the Valaciclovir concentration in XYKX was in direct proportion to the absorption at 310 4nm,C=44 5 905A+1 7 556,r=0 9 998 In the range of 17 50～50 12?g/ml,the podophyllotoxin concentration in XYKX was in direct proportion to the absorption at 292nm,C=97 7 981Ap292+1 3 614,r=0 9 999,AP292=As292-As325 CONCLUSION:The preparation technic of XYKX is simple and the method of quality control is feasible

Objective To explore the effects of coincident infection on treatment response and coronary artery lesion (CAL) outcome in children with Kawasaki disease(KD).Methods A retrospective study of 141 children diagnosed on KD between Jul.2005 and Dec.2006 were performed.Standardized clinical assessments,laboratory examinations microbiology test results plus treatment regimens were reviewed.CAL were visualized by using echocardiography.Infectious agents positive (INF+) and negative (INF-) groups were identified,and clinical assessments,laboratory and treatment data were analyzed.Results 1.Concurrent infections:41%(58/141) of children had one of above confirmed infection at KD diagnosis.2.Treatment response:the presence of infection did not alter the response to treatment with intravenous immunoglobulin (IVIG),with resolution of fever within 72 h in 85% (120/141) children after 1 dose of IVIG (2 g/kg) together with aspirin administration regardless of present or absent infection.3.CAL outcome:in total,56.0% (79/141) of children developed CAL at the time of diagnosis,involving dilatation (91.1%,72/79 cases) and aneurysm (8.9%,7/79 cases),and no giant aneurysm was found.Most CAL were recovered within 1 year after treatment.Incidence of aneurysm in INF+ group was significantly higher than that in INF-group (P=0.019).Conclusions Coincident infection would not affect on the clinical assessment,laboratory test results and treatment response to IVIG in children with KD,but would result in higher risk of serious CAL.Therefore,children with infection at diagnosis on KD will not only accept active treatment in acute phase,but also insist on convalescent care and follow-up visit.

OBJECTIVETo improve the diagnosis and treatment of penile metastasis from rectal carcinoma.

METHODSWe reported a case of penile metastasis secondary to rectal adenocarcinoma, reviewed the relevant literature, and discussed the common origins, clinical features, pathogenic mechanisms, diagnosis and treatment of this disease.

RESULTSThe patient was a 54-year-old male, with metastatic penile tumors secondary to rectal adenocarcinoma, with serious adhesion to the surrounding tissue and metastasis to the liver. As treatment, we performed colostomy to relieve voiding difficulty, followed by combination chemotherapy with oxaliplatin, 5-fluorouracil, and levofolinate. The patient died 10 months later as a result of systemic failure.

CONCLUSIONPenile metastatic malignancy has a poor prognosis. Early diagnosis and combined and individualized therapies may improve the quality of life, relieve pain and prolong the life of the patient.

In the magnetic induction tomography(MIT) system,the electrical conductivity of biological tissue is direct proportion to the phase difference between the excitation signal and the detection signal.To obtain the image of the contribution of tissue's electrical conductivity,the system must have the function of phase detection with high accuracy.The paper focuses on the means of digital phase detection,including FFT method,the correlation method and the classic method,which are ultimately compared with analogue phase detection method.The experimental results show that FFT method and the correlation method,with low error level and high linearity,can better detect the phase difference with the level of 0.1?.The digital phase difference detection provides a kind of effective method for MIT system.

Objective To explore the influence of type 2 diabetes mellitus combined with subclinical hypothyroidism on diabetic vascular complications.Methods One hundred and two patients with type 2 diabetes mellitus were selected.The serum free triiodothyronine (FT3),free thyroxine (FT4),thyroid stimulating hormone (TSH),anti-thyroid peroxidase antibody (TPO-Ab),thyroglobulin antibody (TG-Ab) levels were measured by chemiluminescence method.The patients were divided into type 2 diabctes mellitus combined with subclinical hypothyroidism group (47 cases) and type 2 diabetes mellitus with normal thyroid function group (55 cases) according to the thyroid function.The glycated hemoglobin (HbA1c),total cholesterol (TC),low-density lipoprotein cholesterol (LDL-C),triacylglycerol (TG),high-density lipoprotein cholesterol (HDL-C),urea nitrogen,creatinine and albumin levels were measured.The estimated glomerular filtration rate (eGFR) was calculated according to the formula of modification of diet in renal disease (MDRD).The presence of diabetic retinopathy was examined by fundus examination,and the presence of lower limb artery lesions was measured by vascular ultrasound.All indicators were compared between 2 groups.Results There were no statistical differences in age,disease course,HbA1c,body mass index (BMI),TC,TG,HDL-C,LDL-C,incidence of lower limb artery lesions and incidence of diabetic retinopathy between 2 groups (P＞ 0.05).TheeGRF in type 2 diabetes mellitus combined with subclinical hypothyroidism group was significantly lower than that in type 2 diabetes mellitus with normal thyroid function group:(83.74 ± 21.55) ml/(min· 1.73 m2) vs.(115.02 ± 12.29) ml/(min· 1.73 m2),and there was statistical difference (t =4.274,P ＜ 0.01).The incidence of diabetic nephropathy in type 2 diabetes mellitus combined with subclinical hypothyroidism group was significanlty higher than that in type 2 diabetes mellitus with normal thyroid function group:48.9％ (23/47) vs.23.6％(13/55),and there was statistical difference (x2 =7.103,P＜ 0.01).Logistic regression analysis showed that subclinical hypothyroidism was a risk factor for diabetic nephropathy (OR =0.524,95％ CI 0.12-0.93,P ＜ 0.05),but it was not the risk factor for diabetic retinopathy (OR =0.618,95％ CI0.19-2.16,P =0.475) and lower limb artery lesions (OR =0.485,95％ CI 0.32-2.13,P =0.689).Conclusion Subclinical hypothyroidism in patients with type 2 diabetes mellitus has no obvious effect on lower limb arterial complications and diabetic retinopathy,but may increase the risk of diabetic nephropathy.

Objective To observe the effect of low molecular weight heparin calcium combined with astraga-lus injection in the treatment of diabetic nephropathy.Methods From January 2013 to December 2014,78 patients with stage III diabetic nephropathy in our hospital were enrolled into the study.They were randomly divided into con-trol group(41 cases) and treatment group(37 cases).The control group received general therapy,such as low protein diets,compound alpha keto acid,insulin,irbesartan,simvastatin.The treatment group was treated with low molecular weight heparin calcium and astragalus injection on the basis of general therapy.The changes of urinary albumin and 24 hours urinary protein after treatment in the two groups were observed.Results After treatment,the negative rate of urinary micro albumin in the treatment group ( 75.68%) was significantly higher than that of the control group (29.27%)(χ2 =16.765,P<0.01).24 hour urinary protein of the treatment group[(176.2 ±82.3)mg/24h]was significantly lower than that of the control group[(223.8 ±87.8)mg/24h](t=2.471,P<0.05).Conclusion Low molecular weight heparin calcium combined with astragalus injection can reduce the proteinuria of diabetic nephropa-thy,it is an effective intervention therapy for early diabetic nephropathy.
