Objective To investigate the effects of clinical pathway-based teaching methods in clinical teaching of hematology. Methods Interns, which studied in department of hematology, were classified non-randomized into two groups. The interns in experimental group received idiopathic thrombocytopenic purpura (ITP) clinical pathway-based teaching. And the interns in the control group received the seventh edition textbook of medicine-based traditional teaching. All interns were oral tested when they finished two weeks period clinical studied of hematology. Meanwhile, a questionnaire designed for clinical pathway-based teaching was included in this test only for the experimental group. Results There were 32 interns recruited in the group of clinical pathway-based teaching and 38 interns in the control group of traditional teaching. There were statistically significant differences between the two groups in the fields of the key points about history of diseases ( = 0.0017), assessment of diagnostic criteria and differential diagnosis ( =0.0074), selection of laboratory examination items ( <0.0001) for ITP. The group of clinical pathway-based teaching achieved higher scores than the control group. However, there was no statistically significant difference between the two groups in the field of selection of first-line treatment measure of ITP ( = 0.1155) . Moreover, the control group achieved higher scores than the group of clinical pathway-based teaching in the field of how to treat ITP patients with first-line treatment failure ( =0.0003) . In addition,there were 93.8%interns in the experimental group accepted the new clinical pathway-based teaching tool in the survey. The open-ended question survey showed the clinical pathway teaching method was more simple, intuitive and standardizing than the traditional one. Conclusion The ITP clinical pathway, as an interns teaching tool of hematology, is helpful for understanding more clearly the diagnosis and treatment of ITP. However, an in-depth explanation is necessary combination with textbook of medicine study in the clinical teaching of ITP.

ObjectiveTo evaluate the diagnostic value of immunohistochemistry(IHC) for the identification and localization of Treponema pallidum(TP) in secondary syphilitic lesions.MethodsSkin tissue specimens were obtained from the lesions of 25 patients with secondary syphilis and 15 patients with dermatoses unrelated to TP infection,followed by fixation and embeding.IHC using a polyclonal antibody against TP and Warthin-Starry (W-S) silver stain were carried out respectively to detect TP in these specimens.Results TP was detected in 80.00％ (20/25) of the specimens by IHC,44.00％ by W-S silver stain (Fisher's Exact Test,P =0.046).Of the 20 IHC-based TP-positive specimens,all harbored TP in the epidermis,11 also in the dermis.The density of TP was associated with the types of skin lesions,and sequentially decreased from condyloma latum to papules,maculopapules and maculae(x2 =15.694,P =0.011 ).Spirochetes were not seen in any of the control lesional specimens.ConclusionsIHC is superior to traditional W-S silver stain for detecting spirochetes in secondary syphilitic lesions,and is of great value to the diagnosis of secondary syphilis.The accurate localization of TP by IHC may facilitate the study on the formation of syphilitic lesions.

BACKGROUND: It is manifested in epidemiology and clinical observation that lipoprotein (a) is a new risk factor of cerebrovascular disease and is closely related to cerebral ischemic stroke.OBJECTIVE: To discuss the relationship between levels of high serum lipoprotein (a) and stroke.DESIGN: Case controlled analysis.SETTING: Neurological Institute of Xiangya Hospital of Central South University.METHODS: Totally 294 patients with stroke were selected from Neurological Department of Xiangya Hospital of Central So, uth University between September 1999 and March 2002. Of them, 159 cases were regarded as cerebral infarction group and other 135 cases as acute hypertensive cerebral hemorrhage group. In cerebral infarction group, 109 patients had atherosclerotic cerebral infarction and 50 patients had lacunar cerebral infarction, and 94patients with contimuous health examination were regarded as health examination group. Serum lipoprotein (a) in each group was assayed with "sandwich enzyme-linked immuno-sorbent assay". According to whether the value of lipid was normal or not, patients with atherosclerotic cerebral infarction and acute hypertensive cerebral hemorrhage were divided into two groups. Comparisons between the two groups were assayed with single sample t test, and multiple liner regression was used to assay whether sex, hypertension and value of lipid were related to the level of serum lipoprotein (a).MAIN OUTCOME MEASURES: ① Comparisons of serum lipoprotein (a)among atherosclerotic cerebral infarction group, lacunar cerebral infarction group, acute hypertensive cerebral hemorrhage group and health examination group. ② Correlated analysis between serum lipoprotein (a) and lipid.RESULTS: Among 294 patients, 94 cases in control group entered the final analysis. ① Comparisons of serum lipoprotein (a) among atherosclerotic cerebral infarction group, lacunar cerebral infarction group, acute hypertensive cerebral hemorrhage group and health examination group: Levels of serum lipoprotein (a) in atherosclerotic cerebral infarction group and cerebral hemorrhage group were higher than those in health control group (P ＜ 0.05), and concentration of lipoprotein (a) in atheroosclerotic cerebral infarction group was increased as compared with that in acute hypertensive cerebral hemorrhage group (P ＜ 0.05). Also, level of lipoprotein (a) in lacunar cerebral infarction group was a little higher than that in control group,but the difference was not significant (P ＞ 0.05). ② Correlated analysis between serum lipoprotein (a) and lipid: Levels of lipoprotein (a) in both normal lipid group and abnormal lipid group were assayed with single sample t test, and the results showed that levels in the two groups were similar (P ＞ 0.05). Multiple liner regression was used to assay whether sex,hypertension and value of lipid were related to level of serum lipoprotein (a).CONCLUSION: Levels of lipoprotein (a) may be an independent risk factor for cerebral hemorrhage and atherosclerotic cerebral infarction.

Aim To investigate the effect of phenyle-thanol glycosides from Cistanche tubulosa(CPhGs) on the proliferation and activation of rrPDGF-BB induced HSC and their target points for resisting hepatic fibro-sis,to elucidate the molecular mechanism in molecular level, and provide basic data for the further develop-ment of new drugs. Methods HSCs were cultivated by CPhGs with different concentrations ( 0 , 3. 91 , 7. 81 , 15. 63 , 31. 25 , 62. 50 , 125. 00 , 250. 00 , and 500 mg ·L-1 ) and IC50 of CPhGs was determined. CPhGs with different concentrations ( 25 , 50 , 75 , 100 mg · L-1 ) were selected, and after the cells were stimulated with rrPDGF-BB, cell proliferation was determined by MTT. ERK1/2 ,α-SMA, c-fos, c-jun and Collagen I mRNA and Erk1/2 ,P-Erk1/2 and CollagenⅠprotein ex-pressions were assayed by RT-PCR and Western blot. Results CPhGs of ( 50 ~100 ) mg · L-1 concentra-tions groups could effectively inhibit rrPDGF-BB-medi-ated proliferation(P<0. 05) and CPhGs of(25~100) mg·L-1 concentrations groups had no significant cyto-toxicity( P >0. 05 ) . CPhGs of ( 25 ~100 ) mg · L-1 concentrations groups could inhibit ERK1/2 ,α-SMA,c-fos, c-jun and CollagenⅠmRNA levels, and also ob-viously inhibited Erk1/2 ,P-Erk1/2 and Collagen Ⅰ pro-tein expression on HSC. Conclusions CPhGs has the protective effect against hepatic fibrosis. The mecha-nism of this process may involve the interference with PDGF/ERK1/2 signaling pathway and inhibiting the activation and proliferation of HSC.

OBJECTIVETo compare the efficacy between eccentric fixation and internal fixation for treatment of intertrochanteric fractures of femur,to provide a theoretical basis for the selection of the treatment method of the intertrochanteric fractures of femur.

METHODSFrom February 2007 to January 2010,82 patients with femoral intertrochanteric fracture were treated by internal fixation including 39 cases of eccentric fixation involving 23 males and 6 females, aged from 41 to 81 years old with an average of (62.68±10.69), using the DHS or proximal femoral locking plate; 43 cases of intramedullary fixation involving 15 males, 28 females,aged from 43 to 78 years old with an average of (62.60±8.37),using PFN or PFNA fixed. The surgical incision length, operative time, blood loss and postoperative Harris score between two groups were compared.

RESULTSThe wound of two groups were primary healing without operative complications. All cases received follow-up for an average time of 18.3 months (12 to 28 months). The incision length, operative time and blood loss had a statistically significant difference between two groups (P<0.05). Harris scores of hip joint function at 1 month after operation had statistically significant difference between two groups (P<0.05), and Harris scores at 12 months after operation had no statistical significance difference between two groups. The rate of excellent and good was 89.7% in eccentric fixation group and 90.7% in intramedullary fixation group,the difference was not statistically significant (t=0.0613, P>0.05). In eccentric fixation group, there was 1 case of fracture nonunion with DHS loose and ensuing hip varus deformity. In intramedullary nail fixation group, there was no anti-rotation out,distal intramedullary nail of femoral refracture occurred in 1 case.

CONCLUSIONTwo treatment methods for the treatment of femoral fractures had a good therapeutic effect,but the intramedullary fixation had shorter operative time and less blood loss than the eccentric fixation,it prior to apply to osteoporosis and unstable femoral intertrochanteric fractures.

BACKGROUND:Valgus knee deformity is rare in the clinic. The therapeutic effects of artificial knee arthroplasty are worse than varus knee deformity. There is no unified opinion for replacement approach, soft tissue release method and procedure and prosthetic choice at present.
OBJECTIVE:To summarize case data and to observe clinical effects of total knee arthroplasty for valgus knee deformity.
METHODS:Clinical data of 37 cases of valgus knee deformity (42 knees) undergoing total knee arthroplasty, who were treated by the same group of physicians in the First Department of Orthopedics, Gansu Provincial Hospital of Traditional Chinese Medicine from January 2010 to December 2012 were retrospectively analyzed. There were 11 males (13 knees) and 26 females (29 knees), at the age from 56 to 78 years, with an average age of 63.7 years. The differences in range of motion, femorotibial angle and Hospital for Special Surgery knee score were compared before and after replacement. Clinical effects of total knee arthroplasty for valgus knee deformity were evaluated.
RESULTS AND CONCLUSION:The postoperative fol ow-up lasted from 6 to 36 months. Knee joint range of motion increased from preoperative 68.5° to an average of postoperative 108.5°. Femorotibial angle reduced from preoperative 16.82° to postoperative 5.62° on average. The average Hospital for Special Surgery knee score increased from preoperative 39 points to postoperative 88 points (P<0.05). These results suggested that the curative effect of total knee arthroplasty for valgus knee deformity is proved. Total knee arthroplasty is an effective way to improve deformity.
