We present herein a case of human infestation of canine scabies occuring in a 7l-year-old female patient. Severe pruritic, erythematous papular lesions and excoriation were found over the abdomen, submammary area, and thigh. The itching sensation was aggravated especially at night. Efforts to demonstrate mites from the lesiona of the patient were unsuccessful. Her pet, a small puppy, showed loss of hair and crusted or scaly erythematous patches on the auricles and trunk 1 month prior to her skin lesions. Sarcaptescabiei var. canis were collected from the puppy by brushing the hair snd crusted or scaly patches on its skin. The patient and puppy were treated successfully with application of 25% benzyl benzoate solution.

OBJECTIVETo develop a method of quantitative analysis of multi-components by single marker (QAMS) for simultaneously determining paeoniflorin and albiflorin in Paeoniae Radix Alba.

METHODUsing paeoniflorin as the internal reference substance, the relative correction factor (RCF) of albiflorin was determined by HPLC and UPLC with good reproducibility. The contents of paeoniflorin in 16 samples of Paeoniae Radix Alba were authentically determined by the external standard method, and the content of albiflorin was calculated according to the RCF. The contents of these two components in the samples were determined with the external standard method.

RESULTNo siginificant differences between the quantitative results of QAMS method and external standard method were observe.

CONCLUSIONIt is a convenient and accurate method to determine multi-components when some authentic standard substances were unavailable. It can be used to control the quality of Paeoniae Radix Alba

BACKGROUND AND OBJECTIVES: Angiotensin-receptor blockers (ARBs) have beneficial effects on cardiovascular, metabolic, and inflammatory parameters in addition to controlling blood pressure (BP). However, few comparative clinical studies have been conducted with different ARBs. We compared these effects in patients with uncomplicated hypertension who were receiving telmisartan or valsartan. SUBJECTS AND METHODS: The subjects were patients with essential hypertension (48.4+/-9.6 years) who were randomly assigned to take either telmisartan (80 mg/day, n=30) or valsartan (160 mg/day, n=30) for 12 weeks. Their anthropometric, laboratory, vascular, and echocardiographic data were measured at baseline and at the end of the study. RESULTS: Baseline characteristics were not significantly different between the two groups, except for the carotid-femoral pulse wave velocity (cfPWV; telmisartan group vs. valsartan group; 841.2+/-131.0 vs. 761.1+/-104.4 cm/s, p<0.05). After 12 weeks, BP had fallen to a similar extent with mean reductions in the systolic and diastolic BP of 20.7+/-18.1 and 16.3+/-13.0 mm Hg (p<0.001, respectively) for the telmisartan and 22.5+/-17.0 and 16.8+/-9.3 mm Hg (p<0.001, respectively) for the valsartan group. Although the cfPWV and left ventricular mass index (LVMI) fell significantly only with the administration of telmisartan, they were not significantly different when baseline cfPWV was considered. The differences in the cfPWV and LVMI changes from baseline between the two groups were also not significant after adjusting for baseline cfPWV. No significant changes in other vascular, metabolic, or inflammatory parameters were observed with either treatment. CONCLUSION: The effects of a 12-week treatment with the two ARBs, telmisartan and valsartan, on cardiovascular, metabolic, and inflammatory parameters were not different in patients with uncomplicated hypertension.

Deferasirox is a new oral iron chelator. It is the first oral iron chelator approved in USA by FDA for transfusion-dependent patients above 2 years suffering from severe chronic iron overload. It is also recommended as the initial therapy for patients over the age of 6 years who are suffering from beta-thalassaemia. The clinical study is developing in China. This review focuses the related studies and the latest progression about deferasirox. The phase II and III clinical trials and pharmacokinetics indicated that deferasirox is a safety and effective oral iron chelator, can significantly decrease the myocardial and hepatic iron load, also is easy to accept for patients. The common adverse reactions are gastrointestinal symptom and rash. But it was recently reported that deferasirox has some rare adverse events to which we must attach importance, especially for the special people. Besides the patients with chronic iron overload resulting from blood transfusions (transfusional hemosiderosis), the drug is also used for the patients who has accepted auto-SCT or suffered from reversible renal inadequacy caused by Fanconi syndrome. The standard dosage is not useful to every patient. The clinician should adjust dosage based on the patient's condition and related indexes. The serum ferritin is not one and reliable index to monitoring the effect and adjust the dosage. Otherwise, this review recommends some new characters of deferasirox, e.g. anti-fungus, anti-cell proliferation and so on.

Objective: To evaluate the efficacy and safety of eltrombopag in the treatment of pediatric primary immune thrombocytopenia (ITP) . Methods: The clinical characteristics of 23 pediatric ITP patients who received eltrombopag from May 2015 to March 2019 were retrospectively analyzed. Eltrombopag started with an initial dose of 12.5-50.0 mg/d and the maximum dose was 75.0 mg/d. Results: Among 23 children, there were 11 boys and 12 girls with median age 11.0 (2.0-17.0) years. Four cases were newly diagnosed ITP, the other 8 of persistent ITP and 11 of chronic ITP. The duration of eltrombopag application ranged from 4.5 to 95 weeks (8/23 still ongoing) . The median platelet (PLT) counts at 2 weeks, 4 weeks, 3 months and the 6 months after treatment were 40 (4-170) ×10(9)/L, 20 (4-130) ×10(9)/L, 60 (4-110) ×10(9)/L, and 70 (18-160) ×10(9)/L, which were all significantly higher than that before treatment 14 (2-82) ×10(9)/L (z=-3.440, P=0.001; z=-1.964, P=0.049; z=-4.339, P<0.001;z=-5.794, P<0.001 respectively) . The overall response rate was 60.87% (14/23 cases) . The median time to PLT count ≥30×10(9)/L was 10.5 (3-42) days. Seven patients (30.43%) responded within the first week, and 10 cases (43.48%) achieved PLT counts ≥30×10(9)/L within 2 weeks. All patients were divided into three groups according to the age (<6 years old, 6-12 years old, 13-17 years old) . The response rates were similar in three groups, as 33.33%, 60.00%, 85.71%, respectively. WHO bleeding scores as 0, 1, 2 were corresponded to 4, 12 and 7 patients before treatment. Patient numbers changed to 13, 7, 3 with bleeding scores 0, 1, 2 respectively after treatment (χ(2)=7.558, P=0.006) . Eltrombopag was well tolerated, the common adverse events included elevated transaminase (4 cases) and serum bilirubin (4 cases) ; mild nausea (1 case) , vomiting (1 case) and dizziness (1 case) . No drug withdrawal occurred due to adverse events. Conclusion: Eltrombopag is safe and effective in pediatric patients with primary ITP.

BACKGROUND: Angiotensin II (AngII) and abnormal oscillatory shear stress are highly associated with vascular inflammation including atherosclerosis. However, it is poorly understood how interactions between AngII and shear stress in human aortic endothelial cells (HAEC) are involved in mechanisms by which cellular adhesion molecules are expressed. The purpose of this study was to improve that understanding. METHODS: AngII (10(-7)M for 6 hr) and two-types of shear stress treatments were used: laminar shear stress (LS: unidirectional, 12 dynes/cm2) and oscillatory shear stress (OS: bi-directional, 5 dynes/cm2, 1 Hz) in HAEC. Immunoblotting was used to detect expression of cellular adhesion molecules markers such as vascular cell adhesion molecule 1 (VCAM1) and intercellular adhesion molecule 1 (ICAM1). RESULTS: AngII significantly increased VCAM1 and ICAM1 expression in HAEC that had been reduced due to pretreatment with telmisartan. AngII-LS co-stimulation and AngII-OS co-stimulation significantly increased VCAM1 and ICAM1 expression in HAEC. The expression levels of VCAM1 and ICAM1 were also, significantly reduced when pretreated with telmisartan. However, VCAM1 and ICAM1 expression were significantly reduced under LS and OS stimulation. CONCLUSIONS: Telmisartan may modulate the expressions of VCAM1 and ICAM1 via different types of shear stress in HAEC that are activated by AngII.
