cases of coronary heart disease with the left main coronary artery (LM) Lesion (≥50% stenosis) were analyzed In 8 cases the LM Lesion was only involved,and in the others (43),the LM Lesions were accompanied by other branch lesions of coronary artery Compared with 210 cases of coronary heart disease without LM Lesions,in the LM Lesion groups,the patients clinically manifested severe unstable angina,and the incidences of acute myocardial infarction and sudden death were higher In the two groups of patients with and without LM Lesion The risk factor for coronary heart disease and left ventricular ejection fraction was unsignificantly different The clinical manifestations were similar in the two groups of patient with only LM Lesion and without LM Lesion But when angina onset myocardial ischemia is severe in the patients with only LM Lesion The coronary artery bypass graft may improve symptom and prognosis of patients with LM Lesion

The paper aims to explore the studying method for the pharmacokinetics of drugs in target organs, the pharmacokinetic process of tramadol hydrochloride in the extracellular fluid of frontal cortex (FrCx) of mice was investigated. Six male mice (Kunming strain) were anaesthetized (urethane, 1.8 g x kg(-1), ip) and secured on a stereotaxic frame. A microdialysis probe was implanted into the FrCx and perfused with artificial cerebrospinal fluid at a flow rate of 2 microL x min(-1). One hour later, mice were administrated (ip) with tramadol hydrochloride (50 mg x kg(-1)) and dialysates were collected continuously at 12-min intervals (24 microL each) for 6 h. The tramadol concentration in dialysates was determined by HPLC-Ultraviolet detection method, and the concentration-time curve and pharmacokinetic parameters of tramadol were calculated with DAS software. The results showed that the pharmacokinetic process of tramadol in the FrCx extracellular fluid of mice was fitted to a two-compartment open model, and the main pharmacokinetic parameters t1/2alpha, t1/2beta, t(max), C(max) and AUC(0-infinity) were (0.27 +/- 0.05) h, (2.72 +/- 0.24) h, (0.50 +/- 0.10) h, (2 110.37 +/- 291.22) microg x L(-1) and (4 474.51 +/- 441.79) microg x L(-1) x h, respectively. In conclusion, a studying method for pharmacokinetics of drugs in the target organ is established, which is simple and feasible. Tramadol hydrochloride shows a two-compartment model in the extracellular fluid of the mouse FrCx, and the distribution- and elimination half-life are 0.5 h and 2.7 h, respectively.

Objective To compare the effects of different resuscitation pressure on lung function of rats with uncontrolled hemorrhagic shock.Methods Uncontrolled hemorrhagic shock model of rats was built.Sixty Sprague-Dawley rats were randomly sent into six groups: NC group (the control group),NF group (shock but non-resuscitation),NS40,NS60 group (limited fluid resuscitation),NS80,NS100 group (large-volume fluid resuscitation).When the mean arterial pressure (MAP) reached between 35 mm Hg to 40 mm Hg (1 mm Hg=0.133kPa) resuscitation was begun,normal saline infusion was used to maintain the following desired endpoints.After the fluid resuscitation for one hour,rats of each fluid resuscitation group were given haemostasis and all-out fluid resuscitation,including blood infusion,to maintain the rats' MAP at 90 mm Hg.Results Findings showed that the blood loss in limited fluid resuscitation groups was significantly lower than that in large-volume fluid resuscitation groups at the situation of uncontrolled hemorrhagic shock,damage to lung tissue pathology and acidosis were significantly lower than those in large-volume fluid resuscitation groups.Nine rats in NS60 group survived 72 hours.Three rats in NS40 group survived 72 hours.No rat in NF group as well as in both NS80 and NS100 groups survived 72 hours.Conclusions Uncontrolled hem-orrhagic shock in trauma and different pressure of fluid resuscitation can cause lung injury to varying de-grees.Limited fluid resuscitation provide significant protective effects against such injuries.

OBJECTIVETo analyze the effect of Chinese herbs used by Prof. LI Tao on peripheral blood T subsets in treating multiple sclerosis (MS) by using association rules and statistical methods, thereby providing evidence for optimizing prescriptions.

METHODSData of MS inpatients and outpatients recorded by data collecting system, Xiyuan Hospital, China Academy of Chinese Medical Sciences were resorted. The relationship between Chinese herbs and T cell subsets were analyzed using SPSS17.0 and Aprior module in SPSS Clementine 12.0.

RESULTSRadix bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, and Radix Glycyrrhizae were most commonly used herbal combinations.Radix Aconiti lateralis preparata and Rhizoma Smilacis glabrae were often added. Radix Aconiti lateralis preparata was associated with decreased Th1 cells (confidence level 83.78%, supportive level 36.26%). Decreased Th1 cell was associated with Radix Aconiti lateralis preparata (confidence level 71.26%, supportive level 36.26%).Radix Aconiti lateralis preparata was obviously associated with decreased Th1 cells. Radix Bupleuri, Radix Paeoniae alba, bitter orange, Atractylodes , Radix glycyrrhizae, and Radix Aconiti lateralis preparata could reduce peripheral blood Th1 subsets of MS patients and elevate Th2 subsets (all P < 0.01).

CONCLUSIONSThe herbal combination of Radix Bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, Radix Glycyrrhizae, Rhizoma Smilacis glabrae, and Radix Aconiti lateralis preparata could lower peripheral blood Th1 cells and elevate Th2 cells, and prevent the relapse of MS possibly by reducing Th1 cells and elevating Th2 cells. Especially Radix Aconiti lateralis preparata played important roles in aforesaid changes of Th1 and Th2.

Objective To explore influencing factors for complete resection and operation time of endoscopic submucosal dissection( ESD) for colorectal tumors. Methods This retrospective study included 95 consecutive colorectal tumors in 88 patients whose pathological diagnosis was adenoma and carcinoma, treated with ESD at the Department of Endoscopy of the First Hospital of Jilin University from January 2013 to December 2014. Multiple logistic regression analysis was conducted on the factors related to complete resection and operation time. Results Average tumor size was 28. 7±14. 1 mm(range,8?80 mm), and the average procedure time was 80. 72±63. 90 min. The rate of complete resection was 92. 6%(88/95),and the rate of incomplete resection was 7. 4%(7/95). Multivariate logistic regression analysis revealed that fibrosis (P=0. 012,OR=52. 473, 95%CI:2. 571?1140. 438) contributed to incomplete resection. Fibrosis ( P=0. 001, OR=0. 045, 95%CI:0. 007?0. 289) ,tumor size ( P=0. 035,OR=0. 170, 95%CI:0. 033?0. 884) ,granular?type laterally spreading tumor ( P=0. 013, OR=34. 432, 95%CI:2. 138?554. 476 ) , non?granular?type laterally spreading tumor(P=0. 044,OR=31. 715, 95%CI:1. 093?919. 904) were independent factors for extending operation time of colorectal ESD. Conclusion The severer fibrosis can induce higher rate of incomplete resection. The more severe fibrosis is, the larger tumor size is, and the longer operation time is.

Objective To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) with scissors knife in difficult cases.Methods A total of 36 sessions of ESD in 34 patients were performed from May 2010 to May 2012 with application of new scissors knife.The complications and followup outcomes were recorded.Results All lesions were removed successfully with an en bloc resection rate at 91.7％.Delayed bleeding occurred in 2 patients (5.6％),and both of them were cured sucessfully with endoscopy.No perforation happened and the average hospitalization time was 5 days.Follow-up endoscopy performed 6 or 12 months after ESD in 6 patients revealed no recurrence or residual lesions.Other patients are under follow-up now.Conclusion The scissors knife is easy to manipulate,which can ensure the safety and efficiency of ESD.

Objective To analyze morbidity,mortality and epidemiological characteristics of epidemic encephalitis B (Japanese encephalitis) from 2002 to 2013 in Zunyi.Methods The descriptive and statistical analysis of the incidence and death of epidemic encephalitis B from 2002 to 2013 in Zunyi was carried out.Results The morbidity and mortality were on a downward trend of epidemic encephalitis B in Zunyi from 2002 to 2013;most of the death and incidence cases occurred in July and August from children living scattered and students under age 15;after immunization expansion,the incidence of encephalitis B showed significant differences between ages,occupations,and time points (P<0.05);in the regional distribution of epidemic encephalitis B,incidence and mortality had significant differences (P<0.05).Conclusion Promising results might be generally obtained after expansion of encephalitis B immunization.However,there is a tendency of shifting back in terms of onset age and month.Therefore,comprehensive prevention measures should be implemented according to the epidemiological features of epidemic encephalitis B.
