Objective To improve the understanding of the epidemiology,clinical features,diagnosis and treatment of Tsutsugamushi disease,and reduce the misdiagnosis rate.Methods The clinical data of 56 cases of Tsutsugamushi disease misdiagnosed were analyzed retrospectively.Results 28 cases were misdiagnosed as acute upper respiratory tract infection(50.0%),3 cases were malaria(5.4%),1 case was cholecystitis(1.8%),24 cases were infectious fever(42.8%).The average misdiagnosed time:10.3days.55 patients were found Eschar or ulcer (98.2%),54 cases were found Eschar or ulcer on one part of body,1 case was found two eschars.54 cases had been effectively treated,50 cases were treated with chloramphenicol,4 cases with azithromycin.The average time of temper-ature that dropped to normal were respectively:1.3d,1d.Conclusion awareness of Tsutsugamushi disease should be raised,history seriously should be inquired and specific signs should be identified,which can degrade the misdiagnosis rate and reduce the mortality rate.

AIM and METHODS:To study the effect of Nao-xue-bao at three different doses on blood coagulation,platelet aggregation by observing the changes in activated partial thromboplastin time (APTT), prothrombin time (PT), antithrombin-Ⅲ(AT-III), fibrinogen(Fng), plasminogen(Plg) and platelet aggregation(PAG). RESULTS:Compared with thrombosis group, the rats treated with Naoxuebao showed that the plasma APTT,PT were longer, and the activity of AT-III was increased. The content of Fng was reduced, TT was longer, there was a negative correlation between Fng and TT. Furthermore PAG-1, PAG-5 and PAG-M were reduced. CONCLUSION:Nao-xue-bao could inhibit thrombosis in different keys of blood coagulation.

Objective To investigate the expression of LPS receptor-CD14(CD14) on the membrane of Kupffer′s cells (KCs) induced by Lipopolysaccharide (LPS )and its role in activation of KCs and production of cytokines. Methods KCs were isolated by collagenase perfused Wistar rats and routinely cultured in 24-well dishes for 12 h. Cells were harvested and adjusted to a concentration of 1×106/ml/well and were devided into two groups. Group of LPS: KCs were induced with different concentration of LPS (0, 100 ng/ml, 1 μg/ml and 100 μg/ml). Group of PI-PLC: KCs were pre-incubated for 30 min with one unit of phophatidy linositol specific phospholipase C (PI-PLC) before different concentrations of LPS were added. KCs were cultured for 30 and 60 min respectively. Supernatants were then collected for measuring the level of TNFα and IL-6. Cells were stained by indirect immunofluorescent method ( rabbit anti-CD14 antibody and goat anti-rabbit IgG conjugated with FITC ) and analyzed with flow cytometer (FCM). The percentage and mean fluorescence intensity (FI) of CD14-positive cells were taken as the indexes. Results In LPS group, after incubation of cells with increasing concentration of LPS, a significant increase in the percentage of CD14 positive KCs were found and the mean FI was stronger when compared with the control points or the group of PI-PLC. The levels of TNFα and IL-6 in supernatant also increased (P<0.01). In group of PI-PLC, decreased percentage of CD14 positive KCs and weakened mean FI were found when compared with group of LPS. The increasing production of TNFα and IL-6 slowed down in the group of PI-PLC. Conclusion CD14 expression of KCs might be up-regulated by LPS with increase of some cytokines. The production of cytokines in KCs induced by LPS is partially inhibited by PI-PLC.

Objective:To observe the thrombolytic effect of Naoxuebao in vitro and in vivo.Methods:The changes of thrombus in the carotid arterial,plasma fibrinogen (FIB),thrombin time (TT) and the diameter of blood clot were observed using Naoxuebao (three dose groups) after thrombosis.Results:With Naoxuebao,the time of blood clot was longer,the diameter of blood clot was shortened;carotid arterial thrombosis was dissolved.The contents of FIB decreased,TT was longer,and FIB and TT had negative correlation;whereas,PLG had no obious change.Conclusion:Naoxuebao had thrombolytic effect,but the effect had no relation with plasmin activating.

Objective To evaluate the curative effects of carbon nanoparticles on central lymphnode dis -section in papillary thyroid carcinoma ( PTC) .Methods 72 PTC patients were randomly divided into two groups:carbon nanoparticle group(n=32)and the control group(n=32).Patients in the carbon nanoparticle group were injected with carbon nanoparticles during surgery .Patients in the control group had conventional surgery .The number of lymph nodes being dissected ,lymph node metastasis , and the rate of hypoparathyroidism were compared between the two groups .Results The number of lymph nodes dissected in nanoparticle group ( n =312 ) was much bigger than that in the control group (n=189)(P<0.01;t=8.476).The incidence of hypoparathyroidism in nanoparticle group(n=1)was much lower than that in the control group (n=8)(P<0.05;χ2 =4.571).The metastasis of lymph nodes has no significant difference between the two groups (P>0.01;χ2 =1.048).Conclu-sions The lymphatic tracer technique may improve the number of lymph nodes dissected in central region of PTC and reduce parathyroid gland damage .

Gastric stump carcinoma (GSC) generally refers to the primary cancer in the remnant stomach,which occurs 5 years or latter after subtotal gastrectomy for gastric or duodenal ulcer,or 10 years or latter after gastric cancer resection.Laparoscopic radical gastrectomy for GSC is difficult with low resection rate.Although laparoscopic gastrectomy is technically mature in recent years,there is still few reports about laparoscopic resection for GSC.From January 2009 to June 2012,18 patients with GSC received laparoscopic radical gastrectomy at the General Hospital of Lanzhou Military Area of PLA.Laparoscopic gastrectomy for GSC is technically feasible and safe with satisfactory short-term outcome.Surgeons who have mastered laparoscopic D2 dissection could perform this procedure.
