Objective To investigate the protective effect of theaflavins on thymus injury caused by total body irradiation (TBI).Methods Twenty-five C57BL/6 mice were randomly divided into 5 groups:control group,4 Gy TBI group,4 Gy TBI + 25 mg/kg theaflavins group,4 Gy TBI + 50 mg/kg theaflavins group and 4 Gy TBI + 100 mg/kg theaflavins group.Thymus index and total number of thymocytes were detected at the 14th d post-irradiation to determine the optimal dose of theaflavins.According to this optimal dose,32 C57BL/6 mice were randomly divided into 4 groups:control group,theaflavins group,4 Gy TBI group and 4 Gy TBI + theaflavins group.Thymus histomorphology,CD4CD8 T cell subsets,and reactive oxygen species (ROS) in thymocytes were examined at the 14th d post-irradiation.Results The irradiated thymus exhibited decreased thymus index and total number of thymocytes (P ＜ 0.05),aberrant histomorphology and T cell subsets (P ＜ 0.05),and increased ROS level in thymocytes (P ＜ 0.05).Compared with 4 Gy TBI group,the thymus index and total number of thymocytes were significantly increased in 4 Gy TBI + 50 mg/kg theaflavins group (P ＜ 0.05).The total number of thymocytes was significantly higher in 4 Gy TBI + 50 mg/kg theaflavins group than that in 4 Gy TBI + 25 mg/kg theaflavins group (P ＜ 0.05).Therefore,50 mg/kg theaflavins was chosen as the optimal dose for subsequent experiments.Moreover,the aberrant histomorphology of irradiated thymus was alleviated by theaflavins.A decline in the percentage of CD4-CD8-T cells and an elevation of CD4+CD8-and CD4+CD8+ T cells were found in irradiated mice administered with theaflavins (P ＜ 0.05).Compared with 4 Gy TBI group,the ROS level was significantly decreased in 4 Gy TBI + theaflavins group (P ＜ 0.05).Conclusion Theaflavins exhibits a protective effect on radiation-induced thymus injury.

Objective:To evaluate the effect of continuing intervention on prophylactic application of antibiotics in sterile operation in urology department by clinical pharmacist to provide reference for the clinical prophylactic application of antibiotics. Methods:All cases of discharged patients underwent sterile operation in urology department of our hospital from July 2010 to June 2014 were divided into three groups according to the intervention time and methods: non-intervention group(n=141), stage Ⅰ intervention group(n=139), stage Ⅱ intervention group (n=162) and stage Ⅲ intervention group (n=137). The prophylactic application of antibiotics was statistically analyzed. Results:After the continuing intervention, the prophylactic application rate of antibiotics in the three inter-vention groups was decreased significantly from 100% before the intervention respectively to 34. 5%,18. 5% and 14. 6% after the in-tervention (P<0. 01). The rationality rate of prophylactic application was improved significantly from 36. 9% before the intervention respectively to 58. 3%, 63. 3% and 85. 0% after the intervention (P<0. 01). The course of prophylactic application was decreased significantly from (138.2 ±31.6)h respectively to (89.9 ±48.0)h,(72.8 ±32.5)h and(45.1 ±29.5)h (P<0.01) and the post-operative infection rate was decreased from 2. 8% respectively to 2. 1%,1. 8% and 1. 4%. Conclusion:The pharmaceutical interven-tion is feasible and valid to improve the rational prophylactic use of antibiotics in urological surgery.

Objective: To investigate into the etiological factor,distribution of syndrome(patterns),pathogenesis features as well as the curative effects of small compound prescriptions of(Traditional) Chinese Medicine(TCM) in the treatment of acute stroke in stroke unit.Methods:(Cases) corresponding to diagnosis standards were randomly divided into control group(102 cases) and treatment group(156 cases).Conventional treatment methods were given to cases in control group.On the base of control group,small compound prescriptions were added to in treatment group,successively 14-21 days.The relation between types and time and TCM scale(TCMS),the NIH stroke scale(NIHSS) and Barthel index(BI) were observed in the two groups.Results: Stroke was age-related,the older,the more stroke patients.Stroke was closely related to hypertension.Ascending hyperactivity of liver yang was main type in the previous three days,this type(decreased) with the time going on.On the contrary,the type of wind phlegm and blood stasis was secondly main type in the previous three days,it increased with the time going on.Types of ascending hyperactivity of liver yang,wind phlegm and blood stasis as well as phlegm heat and constipation covered 95 per cent of all patients in the previous 21days.In the two groups,the mean scale of TCM and NIH decreased,and BI increased after treatment,this statistical difference could also be seen between the two groups.Conclusion: Excessive types are main types in the acute stage of stroke.Types of ascending hyperactivity of liver yang,wind phlegm and blood stasis as well as phlegm heat and constipation are its main types.Transferring of ascending hyperactivity of liver yang into endogenous wind may be trigger of reaction link of wind,fire,phlegm and blood stasis in TCM theory.Small compound prescriptions of TCM aiming to clearing away liver fire to stop wind,to activate blood for removing blood stasis and phlegm,to removing phlegm and heat from discharge can reduce scale of TCM and NIH,increase BI in the treatment of patients in stroke unit,which provide beneficial proofs for evaluation of effects of TCM.

Objective To discuss the application value of shear wave elastography (SWE) and superb microvascular imaging (SMI) in pathological grading of breast invasive ductal carcinoma (IDC).MethodsSixty patients with breast tumor were selected,which were totally 64 lesions.Before operation,SWE and SMI pattern were started to detect the lesions.And images in SWE and SMI pattern were saved.All lesions were proved to be IDC and pathological gradings were got according to the pathological result.The mean of Young′s modulus(AveT1) and maximum of Young′s modulus(AveT2) were recorded in SWE pattern,and degree of blood was recorded in SMI pattern followed Adler′s grading standard.Then differences of AveT1,AveT2 and degree of blood in different pathological grading of invasive ductal carcinoma were evaluated.Results ①In pathological grading 1 group,the average of AveT1 was (62.1±10.4)kPa,and the average of AveT2 was (93.0±20.1)kPa.In pathological grading 2 group,the average of AveT1 was (79.8±8.6)kPa,and the average of AveT2 was (120.6±18.7)kPa.In pathological grading 3 group,the average of AveT1 was (92.6±12.1)kPa,and the average of AveT2 was (137.3±21.5)kPa.The AveT1 and AveT2 were gradually growing with higher pathological grading of breast invasive ductal carcinoma,which were statistically significant (P<0.05).②In pathological grading 1 group,there were 7 cases in the degree of blood 0-Ⅰ and 14 in the degree of blood Ⅱ-Ⅲ.In pathological grading 2 group,there were 3 cases in the degree of blood 0-Ⅰ and 18 cases in the degree of blood Ⅱ-Ⅲ.In pathological grading 3 group,there were only 1 case in the degree of blood 0-Ⅰ and 21 cases in the degree of blood Ⅱ-Ⅲ.There were more lesions of rich blood with higher pathological grading of breast invasive ductal carcinoma,which was statistically significant (P<0.05).Conclusions There are differences of elastography and degree of blood in different pathological grading of breast invasive ductal carcinoma,SWE and SMI can prompt pathological grading and provide important clinical reference value.
