Objective To evaluate the clinical efficacy of integration of traditional Chinese and western medicine (ITWM) or pure western medicine on the patients with immune thrombocytopenia (ITP). Methods Randomized controlled trials (RCTs) on ITWM treatment of ITP were searched in PubMed, EMBASE, Wanfang database, CBMDisc, CNKI and VIP. Quality of the RCTs was evaluated strictly, and statistical analysis was performed with Cochrane Collaboration’s RevMan5.1.7 software. Results Twenty-two trials involving 1527 patients were included. The results of Meta-analysis showed that the ITWM treatment of ITP significantly improved the total effective rate [RR=1.23, 95%CI (1.17, 1.29), P<0.000 01] compared with that of pure western medicine treatment. Funnel plot showed that publication bias was small. Meanwhile, peripheral platelet count and the number of megakaryocyte which can generate platelet in bone marrow increased, obvious advantage was showed in long-term effect, and adverse reactions were reduced with ITWM treatment in ITP patients. Conclusion The existed limited evidences suggest that ITWM treatment of ITP can significantly improve clinical efficacy. The quantity and quality of research literature were limited, and well-designed randomized double-blind controlled trials with large sample and multi-centers are required for a more reliable conclusion.

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.

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.

Objective To assess the interobserver reliability and intraobserver reproducibility of Neer classification system and its influencing factors.Methods The present study reviewed the series preoperative radiographs (including those of scapular anteroposterior view,scapular lateral view and modified Velpeau axillary view and an axial CT scan) of 40 patients who had been treated in our department from January 2010 to December 2010 for proximal humeral fractures.The radiographs were assessed by 12 individual observers on 2 separate occasions with an interval of 3 months at least Half of the observers (the professional group; n =6) had received a shoulder fellowship training and the other half (the control group; n =6) had not All the observers were asked to categorize the radiographs according to the Neer classification system of 16 types of fractures in a same process.The reliability and reproducibility of the system were assessed with the Kappa statistics.Comparisons of classification agreement were made between the professional group and the control group.We also evaluated the simplified Neer system of only 6 types of fractures with recombinant data.Results The interobserver reliability coefficients were 0.534 and 0.473 for the first and second assessments,with an intraobserver reproducibility coefficient of 0.669.The agreement level in the professional group was significantly higher than in the control group ( P ＜ 0.05).The interobserver reliability coefficients of the simplified Neer system were 0.581 and 0.502,with an intraobserver reproducibility coefficient of 0.680.Use of the modified Neer system did not elevate the agreement level beyond the moderate range.The classification was agreed on by all the observers in 17.5％ of the fractures during the first assessment and in 15.0％ during the second assessment.Conclusions Neer classification may have fair interobserver reliability and moderate intraobserver reproducibility.Experience of shoulder fellowship training is an important factor influencing the reliability of the Neer system.Simplification of the system may not help increase its reliability.

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.

Objective To evaluate the clinical efficacy of neoadjuvant chemo radiotherapy combined with surgical treatment for advanced rectal cancer.Methods Fifty-one patients with advanced rectal cancer were randomly divided into treatment group and control group by random number table.In treatment group,26 cases received three-dimensional conformal radiotherapy synchronization XELOX chemotherapy for 2 cycles,then they received radical resection after 4-6 weeks.Twenty-five cases in control group received neoadjuvant chemotherapy with XELOX for 2 cycles,then received radical resection.Results The objective response rate in treatment group was 84.6％ (22/26),and in control group was 60.0％(15/25),there was significant difference between two groups (P =0.049).Radical resection in treatment group was 96.2％ (25/26),significantly higher than that in control group 76.0％ (19/25)(P =0.037).The sphincter preservation rate in treatment group was 61.5％ (16/26),and in control group was 20.0％ (5/25),there was significant difference between two groups (P =0.003).The pathologic complete response rate in treatment group was 26.9％ (7/26),significantly higher than that in control group 4.0％ (1/25)(P =0.024).The 1,2 and 3 year survival rate in treatment group were 88.0％(22/25),60.0％(15/25),32.0％(8/25),which were significantly higher than those in control group 62.5％ (15/24),29.2％ (7/24),8.3％ (2/24) (P =0.038,0.030,0.040).The 1,2,and 3 year recurrence rate in treatment group were 8.0％(2/25),20.0％(5/25),36.0％ (9/25),which were significantly lower than those in control group 33.3％ (8/24),44.8％(12/24),66.7％ (16/24) (P=0.028,0.027,0.032).Conclusion Neoadjuvant chemoradiotherapy can improve the rate of surgical resection,sphincter preservation and prolong survival of rectal cancer,it can be used as a kind of effective treatment for rectal cancer.

Objective To study the effect of Xuebijing, a Chinese traditional medicine injection, on the THP-1 cells challenged by endotoxin, and to explore whether it induces endotoxin tolerance. Methods The THP-1 cells were pretreated with Xuebijing in different concentrations (10, 25, 50 mg/mL) and times (4, 12, 24 hours), and then challenged by endotoxin. The level of TNF-α in culture supernatant was detected by ELISA assay, and the expression of TLR4 and IRAK-M mRNA were detected by Real time-PCR technique. Results There was no significant difference in TNF-α level among all the groups (pretreated with different concentrations of Xuebijing for different time) (P>0.05). Only in 50 mg/mL Xuebijing group, TLR4 mRNA was 1.547-fold increase in 24 h than in 4 h group (P<0.05). Only when pretreated for 24 h, IRAK-M mRNA was 1.349-fold increase in 50 mg/mL Xuebijing group than in control group (P<0.05). However,there was no significant difference among other groups (P>0.05). Conclusions Xuebijing can not block the release of TNF-α from the THP-1 cells challenged by endotoxin;and it does not induce endotoxin tolerance. When pretreated with high concentration of Xuebijing for long time, the expression of both TLR4 and IRAK-M mRNA is up-regulated, but its significance is not yet clear.
