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.

Objective:To verify the effects of microlecture based on robot carrier on standardized residency training of orthopedics.Methods:Sixty orthopedic residents from our hospital were divided into two groups according to different training methods. One was control group ( n = 30), receiving regular training methods, and the other one was experimental group ( n = 30), receiving additional microlecture based on robot carrier besides regular training methods. The teaching effects of the two groups were compared after the training in orthopedics department. SPSS 20.0 was used for t test. Results:There was no significant difference between the experimental group and the control group in theoretical tests results [(88.63±10.24) vs. (87.85±9.62), P > 0.05]. The operation test scores in experimental group (92.12±7.52) were significantly better than that in control group (85.35±8.12), with statistical significance ( P < 0.05). The satisfaction scores for teaching in experimental group (90.00%) was significantly higher than that in control group (70.00%) ( P < 0.05). Conclusion:Microlecture based on robot carrier could enhance abilities of skills operation for orthopedic residents during the standardized residency training and improve their satisfaction for the teaching effect.

Objective To investigate the effects of Buyang-Huanwu decoction combined with western medicine on early diabetic renal injury.Methods 200 cases of early diabetic renal injury were randomly recruited into study group and control group,with 100 cases in each group.The control group was treated with insulin injection and oral benazepril hydrochloride,and the blood pressure,blood lipid changes were closely monitored; while the study group was additionally treated with Buyang-Huanwu decoction on the basis of the control group.Results The total therapeutic effects in the study group was significantly higher than the control group (x2=15.62,P＜0.01).The values of FBG,2 h PG,DBP,SBP,HbAlc in both groups were significantly reduced after the treatment (P＜0.05,t=4.23,4.47,3.59,3.87,3.99 in the study group,t=4.34,4.76,4.05,3.78,3.69 in the control group) ; but the difference between the two groups had no significance (P＞0.05).Before treatment rnALB,Urea,Cr,TG and TC were not significantly different (P＞0.05) ; the values of mALB,Ureaand Cr were significantly reduced in the study group after the treatment (P＜0.05,t=4.56,3.73,3.28);especially mALB in the study group was obviously lower than the control group (P＜0.05,t=5.01).Conclusion Buyang-Huanwu decoction combined with western medicine was effective to treat early renal damage of type 2 diabetes,with the functions of reducing urinary protein,improving microcirculation and protecting renal function.

As the development of functional and molecular imaging,PET/CT gradually becomes one of methods in optimizing cancer radiotherapy treatment planning.Currently,numerous hospitals routinely use 18F-FDG PET/CT for the delineation of target volume in esophageal carcinoma (EC).However,the validity of 18F-FDG PET/CT in the delineation of target volume for EC is limited and needs further clinical validation.This review focuses on the value and validity of 18F-FDG PET/CT in the delineation of gross tumor target volume of EC primary lesions and regional lymph nodes.

Objective To summarize the clinical characteristics.diagnosis and treatment of familial papillary thyroid microcarcinoma(PTMC).Method The clinical data of 8 cases of familial PTMC admitted from October 2004 to January 2005 were analyzed.Results All patients were followed-up during 9 to 13(mean 10.8)months. No one suffered recurrence and dead. PTMC was found in 2 cases incidentally from thyroid specimens removed for supposed benign disease, another 6 cases were doubtful of cancer before operation and were identified by frozen section.Upper deep cervical lymph nodes were involved in 2 eases with lymph node metastasis. Lymph node metastasis in eases of multifoeal cancer in the affected lobe or of both lobe was significantly higher than those in monofoccal cancer in uni-lobe. Conclusions Most of the PTMC are found among the benign nodules during operation or within the pathological specimens,and familialPTMC are rather rare. Careful palpation,color Doppler uhrasonography, exploratory operation and frozen section are very important factors to heighten diagnosis of PTMC. Lobectomy is the routine radical operation.

The influences of propylene glycol mannate sulfate (PGMS) on experimental thrombosis and thrombolysis in vivo were studies after iv 8. 125, 6. 25, 12. 5 , 25mg/Kg in rabbits, and the effect of antithrombosis of PGMS was compared with that of heparin. The results showed that PGMS possessed remarkable effect of antithrombosis. In order to explore the mechanism of antithrombosis of PGMS, we studied the influences on the fibrinolytic and coagulant function of rabbits. The results showed that PGMS can pronouncedly prolong the prothrombin time (PT), thrombin time (TT), kaolin partial thromboplastin time (KPTT), and enhance the activity of antithrombin-III (AT -III). PGMS can cause a remarkable increase in fibrin degradation product (FDP) , shorten euglobulin lysis time (ELT) , and a decrease in the contents of fibrinogen and plasminogen activity. These results suggested that PGMS probably exert the antithrombotic effect by inhibiting coagulation and activating fibrinolysis.

Objective:To investigate the expression of CD55 in triple-negative breast cancer (TNBC) and its correlations with prognosis.Methods: The expressions of CD55 was detected by immunohistochemistry Streptavidin-Peroxidase method in 100 cases of triple-negative breast cancer and 50 cases of adjacent-carcinoma tissues, with clinical and pathological features and follow-up data, the Cox model analysis was established and to analyze the prognostic factors. Results: The positive expression of CD55 was 56.0% in the tissues from triple-negative breast cancer, whereas its positive rate was 8.0% in the corresponding adjacent breast tissues, with statistical significance (x2=32.0,P<0.05). The expression of CD55 was significantly related with tumor size, clinical stage and axillary lymph node metastases (x2=7.404,x2=8.688,x2=4.802;P<0.05); the expression of CD55 did not show correlation to age, and histologic grade. Multivariate analysis showed that the age, clinical stage, CD55 protein expression and axillary lymph node metastasis were the independent risk factors affecting the 5-year disease-free rate of patients and that clinical stage and axillary lymph node metastasis were the independent risk factors affecting the 5-year overall rate of patients.Conclusion: The expression of CD55 might be related to the development and prognosis of triple-negative breast cancer. The expression of CD55 may be used as one of the indicators in determining the progress and prognosis of TNBC.
