Objective To explore the rationality of clinical blood transfusion since the Ministry of Health enacted the The Technical Criterion of Clinic Blood Transfusion' in 2000. Methods Retrieved the literatures on the appraisal of rationality of clinic blood transfusion published in core journal between 2000 and 2010, and analyzed the rationality of clinical blood transfusion in recent 10 years. Results In 35 literatures entered, the proportion of appropriate blood transfusion of platelet was the highest compaved with the lowest proportion of plasma. the proportion of appropriate blood transfusion in operational department is higher than that in non-operational department. The primary reason of inappropriate blood transfusion is transfusion without indications. Conclusion The proportion of appropriate blood transfusion in china is low. The government should enhance the regulation of blood usage,and the public should he educated to realize the importarce of appropriote blood transfusion in order to promote it to develop healthily.

In clinical practice,regional portal hypertension is infrequent,but it is the only type which could be cured of portal hypertension.Pancreatic diseases are the chief pathogeny of regional portal hypertension,and the obstruction of spleen vein is the basic reason.The common clinical manifestation is isolatism varicose veins of pylorus.The golden standard of its iconography diagnosis is DSA,and the treatment should follow the individual principle.The splenectomy is the basic measure for them who have UGIB or hypersplenism.This is a review about recent advance in regional portal hypertension of etiology and classification,pathology and physiology,clinical manifestation,diagnosis,radiographic examination,cure,and so on.

After major operation,a series of complicated pathological and physiological changes will occur during the trauma and stress state.The protein synthesis is affected,which results in negative nitrogen balance.In addition,the release of inflammatory factors can damage the capillary endothelial cells and increase the permeability of micrangium,induce vascular colloidal albumin leakage to the extravascular tissue,decrease plasma albumin,make wound edema,eventually lead to postoperative hypoproteinemia.Except for albumin supplement,it should be aimed at the mechanism to control the stress response and reduce the leakage caused by the release of inflammatory factors to solve this problem radically in clinical work.The reports about the causes and treatment of hypoproteinemia after major surgery were reviewed to provide evidence for clinical treatment.

Objective To make the detection results of the different automated hematology analyzers in laboratory to be reliable and comparable.Methods With the Beckman Coulter LH750 after calibration as the reference instrument,the fresh whole blood was extracted from the patient and divided into 3 equal parts after mixing evenly.The first part was determined the target value in the LH750 instrument;the second part was used to calibrate the HMX and ABX PENTRA 60 instruments and the third part served as a calibration validation.After calibration,the fresh whole blood of patient was performed the detection for conducting the accuracy evaluation.Results After calibration,the detection results of RBC,HGB,WBC,HCT,MCV and PLT by each instrument were largely improved and the error of the results was less than 1/3 of CLIA′88 requirements.Conclusion Adopting fresh whole blood for calibrating the hematology analyzer is feasible.

The pain relieving degree and the overall therapeutic effect were assessed using the Visual Analogue Scale (VAS) and theCriteria of Syndrome Diagnosis and Therapeutic Effect in Traditional Chinese Medicinein the patients after treatment.ResultThe pain relieving degree and the overall therapeutic effect were more remarkable in the treatment group than in the control group (P<0.05).ConclusionPricking-cupping bloodletting plus microwave therapy can effectively heighten the pain relieving degree and the overall therapeutic effect in treating patients with intractable tennis elbow.

Objective To investigate expressions of microRNA-21 (miR-21),PTEN,NF-κB,and caspase-9 in colon carcinoma and their possible mechanisms in progression of tumor.Methods Expressions of above-mentioned indexes and percentage of apoptotic cells in colon carcinoma,colon adenoma,and normal tissue specimen were detected.Results Expressions of miR-21,PTEN,N F-κB,and caspase9 in normal tissue were 0.39 ±0.02,50％,25％,and 50％.Expressions of them in colon adenoma were 0.62 ±0.06,50％,35％,and 55％,and those in colon carcinoma were 0.88 ±0.04,30％,75％,and 20％.Percentage of apoptotic cells were (24.64 ± 7.66) ％,(15.86 ± 1.44) ％,and (6.20 ± 2.57) ％,respectively.The above P-values were all less than 0.05.Expression of miR-21 was positively correlated with TNM stage,depth of infiltration,differentiated level and expression of NF-κB while inversely correlated with PTEN and caspase-9 expressions and percentage of apoptotic cells.The r-values were 0.647,0.297,0.259,0.519,-0.299,-0.388,and-0.931,respectively.Conclusions Hyperexpression of miR-21 participated in progression of colon carcinoma probably through down-regulating expressions of PTEN and caspase-9 and up-regulating expression of NF-κB and then suppressing cell apoptosis.

Objective:To observe the anatomic characteristics of supratubal recess and the morphological change of it in the sick ear. To investigate the relation between the morphological changes of supratubal recess and otitis media.Method:Using high resolution CT to observe and measure the supratubal recess of the normal ears and the ailing ones.Result:For the normal adults, the anteroposterior diameter of the supratubal recess is(3.83±1.28)mm,the vertical diameter(3.67±1.14)mm,the height(3.76±0.36)mm;and the length of the cog is(2.84±0.38)mm.The size of the supratubal recess showed no significant difference between left and right(P＞0.05).There was no relationship between the size of the supratubal recess and pneumatization of mastoid cells (P＞0.05).There was significant differences in size of the supratubal recess between normal ears and the ears with cholesteatoma(P＜0.05),but there was no relationship between the size of the supratubal recess and pneumatization of mastoid cells(P＞0.05)in the ears with cholesteatoma.There was no significant differences in size of the supratubal recess between normal ears and the ears with chronic otitis media(P＞0.05).In the ears with cholesteatoma,40% had osseous destruction in supratubal recess.Conclusion:For the normal adults, the size of the supratubal recess showed no significant difference between left and right, and there was no relationship between the size of the supratubal recess and pneumatization of mastoid cells. Anterior tympanic isthmus , posterior tympanic isthmus and supratubal recess which is the supplement of the formers constitute the air way between attic and mesotympanum. The supratubal recess of the cholesteatoma is smaller than the normal, when the eustachian tube dysfunction occurs, the air way in the middle ear would herein be affected, and cholesteatoma forms eventually. There was no significant differences in size of the supratubal recess between normal ears and ears with chronic oti-tis media, as in the clinic.The effect of the supratubal recess should be taken into account when we consider the pathogeny and treatment of the middle ear cholesteatoma.
