OBJECTIVETo explore the effect of reduction and fixation with multi-Kirschner wires for treatment of Lisfranc fracture-dislocations.

METHODSThere were 49 patients (37 male and 12 female aged from 20 to 28 years old) involved in the study. According to the Myserson damage typing, type A in 12 cases, B1 in 3, B2 in 28, C1 in 4 and C2 in 2. Kirschner wires were applied to fix and reconstruct the three-column in three directions according to the structural characteristic of midfoot. Reconstruction of three-column needed not only to reduce and to fix every single column, but also to establish union of the columns.

RESULTSAccording to the evaluation of AOFAS for midfoot, 14 cases were excellent (90 to100), 22 cases good (80 to 89), 8 cases fair (70 to 79) and 5 cases poor (60 to 69), with an average score of 84.200+/-9.663.

CONCLUSIONThe diagnosis and treatment of Lisfranc fracture-dislocations should comply with the theory of three-column reconstruction of foot arch, which can achieve the static balance of biomechanics and provide a stable environment for healing of fracture and soft tissue. Reduction and fixation with multi-Kirschner wires is an effective treatment method for Lisfranc fracture-dislocations.

ObjectiveTo examine the prognostic value of 99mTC-MIBI single-photon emission computed tomography (SPECT) in patients with suspected or diagnosed coronary artery disease (CAD).Methods116 patients with suspected or diagnosed CAD were examined with 99m TC-MIBI SPECT exercise and rest myocardial imagings, and followed by investigation of cardiac events.Results Follow-up information was complete in 106 patients. Over an average follow-up of 25±8 months, cardiac events occurred in 11 patients. Univariate analyses showed that age, old myocardial infarction, exercise peak heart rate, the change in heart rate from rest to exercise peak, exercise peak systolic blood pressure, the change in systolic blood pressure from rest to exercise peak, abnormal myocardial imaging, the number of myocardial perfusion defect and ischemic volume rate (IVR) were the effective predictors of subsequent cardiac events. Multivariate stepwise Logistic regression analyses revealed that the size of IVR was the only variable with independent predictive value for occurrence of subsequent cardiac events. IVR more than 25% was associated with a significantly increased frequency of subsequent cardiac events (relative risk ratio was 5.9, P<0.005). IVR less than 25% or even normal myocardial perfusion imaging was associated with a very low-risk of cardiac event and a very good prognosis.Conclusion 99mTC-MIBI SPECT myocardial imaging is the most effective noninvasive technique that predicted the occurrence of cardiac event in patients with suspected or diagnosed CAD. According to the size of IVR, high-risk and low-risk patients can be effectively identified.

OBJECTIVETo summarize the clinical characteristics of secondary coagulation disorders caused by exposure to poison (raticide) in children and to investigate the diagnosis and corresponding treatment.

METHODThe process of diagnosis, clinical characteristics, response to treatment and the prognosis were analyzed.

RESULTSThe main clinical manifestation was mucosal bleeding (66.6%), including epistaxis, gingival bleeding, hematomas and so on. All these children were previously well and had no history of bleeding. Activated partial thromboplastin time (APTT) and prothrombin time (PT) were prolonged, factor II was undetectable and the levels of factors VII, IX, and X were lower. The fibrinogen was normal. A raticide was detected in blood and urine of 13 children although 12 of the patients had no definite history of raticide ingestion. Prothrombin complex, fresh frozen plasma and vitamin K(1) were effective in these cases. However, 2 - 3 weeks later, 6 patients presented with recurrent bleeding.

CONCLUSIONFor children with secondary coagulation disorders of unknown cause, intoxication of raticide should be considered. The administration of blood coagulation factors and vitamin K(1) are effective in early treatment, and the treatment period should be more than 2 months. The PT and APTT should be followed up. Vitamin K(1) should be stopped when PT and APTT are normal.

OBJECTIVETo establish a new quality evaluation method for traditional Chinese medicine preparations, using one chemical reference substance to calcutate multi-components simultaneously.

METHODEmployed puerarin as the maker component, puerarin relative correction factors (RCF) of salvianolic acid B to puerarin and paidzein to puerarin were calcatated in the chromatographic conditions for determination of the three components in Guanmaikang capsules. The contents of Puerarin were determined by external standard method, and those of salvianolic acid B and paidzein were calculated by puerarin and their RCF. The accuracy of the new method was evaluated by comparing the calculated contents with the determined.

RESULTThe analysis methods were established, and it has been no significant difference between the calculated contents and determined contents.

CONCLUSIONSThe method can control the components without providing salvianolic acid B and paidzein reference. It is to be a suitable quality evaluation pattern for TCM Preparation.

The elucidation of vapor-liquid equilibrium (VLE) of the halogenated silane was necessary for the production of silicon derivatives, especially for methylvinyldichlorosilane, due to the lack of the relevant reports. Isobaric VLE for the system methyldichlorosilane-dimethyldichlorosilane-benzene and isobaric VLE of the three binary systems were measured with a new pump-ebulliometer at the pressure of 101.325 kPa. These binary compositions of the equilibrium vapor were calculated according to the Q function of molar excess Gibbs energy by the indirect method and the resulted VLE data agreed well with the thermodynamic consistency. Moreover, the experimental data were correlated with the Wilson, NRTL, Margules and van Laar equations by means of the least-squares fit, the acquired optimal interaction parameters were fitted to experimental vapor-liquid equilibrium data for binary systems. The binary parameters of Wilson equation were also used to calculate the bubble point temperature and the vapor phase composition for the ternary mixtures without any additional adjustment. The predicted vapor-liquid equilibrium for the ternary system was in a good agreement with the experimental results. The VLE of binary and multilateral systems provided essential theory for the production of the halogenated silane.

OBJECTIVETo observe the therapeutic effect of shengxuening (SXN) in treating iron-deficiency anemia (IDA) and to explore its molecular mechanism on iron metabolism balance regulation.

METHODSPatients with IDA were randomly divided into the treated group and the control group, 50 in each group. They were treated with SXN (0.1 g, three times per day) and ferrous gluconate (0.1 g, three times per day) respectively, for 30 days. Levels of serum iron (Fe), total iron binding capacity (TIBC), transferrin saturation (TS), serum ferritin (SF), transferrin (Tf), soluble transferrin receptor (sTfR) and blood routine test, as well as scoring of TCM qi-blood deficiency Syndrome were conducted before and after treatment.

RESULTSThe total effective rate in the treated group reached 92%, it was shown that SXN could improve the iron metabolism, increase levels of Fe, TS, SF and reduce levels of TIBC, Tf, sTfR, it has obvious effect in promoting erythrocyte generation and could promote formation of leucocytes and platelets. The total effective rate in the control group was 32%, which was significantly lower than that in the treated group (P < 0.01).

CONCLUSIONThe effect of SXN in treating IDA and qi-blood deficiency Syndrome is evident, it could improve the iron metabolism, increase levels of Fe, TS, SF and lower levels of TIBC, Tf, sTfR.

OBJECTIVETo investigate the effect of ursolic acid (UA) on the alloxan-induced kidney injury in diabetic mice and explored its possible mechanisms.

METHODSDiabetes mellitus was induced in male Kunming mice by an injection of alloxan (70 mg/kg, i.v.). After 72 hours, blood glucose levels were detected and mice with blood glucose levels over 13.9 mmol/L were considered as diabetic and selected for further experiment. Thirty mice were randomly divided into three groups: control, diabetic and diabetic + UA(35 mg/kg/d, i.g. continuously for 8 weeks). Blood glucose concentration, organ coefficient of kidney, blood urea nitrogen (BUN), creatinine (Cr) as well as renal tissue levels of superoxide dismutase (SOD), methane dicarboxylic aldehyde (MDA), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were determined. Pathology of the renal tissue was measured by hematoxylin-eosin staining.

RESULTSCompared to the control group, blood glucose, organ coefficient of kidney, BUN and Cr increased significantly. In addition, SOD activities was reduced markedly and levels of MDA and inflammatory factors (TNF-α, IL-6) increased significantly. Renal cells from model group rats showed atrophy and disordered after HE staining and infiltration of inflammatory cells also appeared in renal tissue of the model group. These changes were significantly attenuated in the diabetic group treated with UA.

CONCLUSIONUA can significantly relieve renal damage in mice with diabetic nephropathy induced by alloxan, which might be related to decreased blood glucose level, antioxidation effect and inhibiting the production of inflammatory factors such as TNF-α and IL-6.
