BACKGROUND:Schatzker V and VI tibial plateau fractures are often accompanied by severe articular facet colapse, separation of tibial condyles, damage of soft tissue and peripheral blood vessels. To reduce soft tissue damage, clinical treatments include limited open and reduction, Kirschner wire internal fixation and external fixation, however, these treatments are ineffective for the reduction of articular facet. OBJECTIVE: To evaluate the biocompatibility of titanium aloy locking compression plate fixation through the medial or posteromedial combined anterolateral approaches for treatment of Schatzker V and VI tibial plateau fractures. METHODS:Fifty patients of Schatzker V and VI tibial plateau fractures recruited from our hospital were analyzed retrospectively, and were treated with locking plate fixation through the combined approaches. The repair effect in patients was observed. RESULTS AND CONCLUSION:After plate fixation, the fractures in 50 patients were clinicaly healed, no cases appeared nonunion, loosening or breakage. According to the Rasmussen Rating, anatomical location average score was (14.3±1.9) points, with the good rate of 90%; average score of knee function was (24.3±2.5) points, with the good rate of 84%. At 1 year post-surgery, knee flexion range was 100°-130°, average 115°. Experimental findings indicate that, the plate fixation through the combined approaches can achieve good stability, good fracture reduction, and good functional recovery in treatment of Schatzker V and VI tibial plateau fractures.

Objective To evaluate the use of LHRH A for treating prostatic cancer with the occurrence of metastasis or recurrence after castration. Methods LHRH A has been instituted to 9 cases of pathologically verified prostatic cancer with the occurrence of metastasis or recurrence after castration.The therapeutic results were studied. Results Ideal improvement was noted in 4 with all the parameters turned normal.These 4 patients have survived well for 7,3,2 and 1 year respectively.Marked improvement occurred in 2 with part of the parameters turned normal or markedly improved shortly after the treatment.The condition of 1 patient became stable with drop of blood PSA and shrinkage of the prostatic mass.In 3 patients,the metastatic lesion became stable.with the use of LHRH A,the penis became markedly atrophic. Conclusions LHRH A is markedly effective in most cases of prostatic cancer with the occurrence of metastasis or recurrence after castration.The therapeutic efficacy depends on the sensitivity of the prostate cancer cells to the drug.Drug resistance may issue as time goes by.

AIM: To study the therapeutical effects of salvianolic acid B (Sal B) on myocardial infarction(MI) in dogs. METHODS : The models of myocardial infarction were produced by ligation of the left anterior descending (LAD) coronary artery in the anaesthetized dogs. The extent of myocardial ischemia was detected by epicardial-electrocardiogram and the extent of infarction was determhled by N-BT staining method. The parameter of lactate dehydrogenase was determined in the serums of dogs. RESULTS : It was indicated that the adminstration of Sal B(1、3 and 10mg/kg) by the way of intravenous injection reduced the extent of myocardial infarction (N-ST) ( P

Aim To investigate the effects of anti-morphine vaccines on pharmacological actions of morphine in mice.Methods Morphine-6-succinyl and morphine were conjugated respectively with Blue Carrier(BC) in the presence of carbodi-imide.After being immunized with both vaccines(M-BC,M-6-S-BC),the withdrawal syndrome and the abirritation were observed in mice.Results The withdrawal syndrome of the immune mice with M-6-S-BC and M-BC vaccines were reduced markedly compared with the model group,the skipping times were decreased and the latency was longer(P

This paper described the progress in therapeutics of drug dependence by opioids, involved in usages of opiate receptor agitations, non-opiate receptor agitations, non-drug treatment, and immunosuppressive therapy.

AIM: To explore the effects of Compound Yi-Zhi (YZC) on learning and memory capacity and free radical metabolism in D-galactose induced mice dementia model. METHODS: The mice dementia model was induced by a daily D-galactose 0.15 g?kg -1 sc for 45 d and after 5 d D-galactose injection, the mice were treated with three doses of YZC once a day for 40 d. In order to find out the influence of YZC on the models learning and memory capability and free radical metabolism system, Y-maze test was introduced for the former and superoxide dismutase (SOD) and malondialdehyde (MDA) tests for the latter. RESULTS: Compared with the D-galactose model group, three doses of YZC administration ( 0.108, 0.217, 0.433 g?kg -1) were all shown to significantly reduced the times of learning/memory in Y-maze test from 31.35? 8.97/ 17.12? 5.57 to 19.67? 8.07/ 11.27? 6.65, to 14.00? 6.84/ 8.29? 5.95, and to 11.41? 5.99/ 6.24? 4.97, respectively. For SOD, the administrations of 0.108 and 0.433 g?kg -1 YZC could increase the activity of SOD from 17.69? 3.14 to 26.94? 4.46, and to 21.33? 3.63 nU?mg -1 pro. While for MDA, all the three doses of YZC could decrease the level of MDA from 4.08? 0.88 to 2.82? 0.75, to 2.10? 0.42, and to 2.35? 0.39 nmol?mg -1 pro in the mice brain tissue, respectively. CONCLUSION: YZC can improve the D-galactose induced learning and memory dysfunction, and the action may be related to the improvement of antioxidase activity in the model mice brains.

Traditionally,the nellrorl of central nervous system has been regarded as lack of regeneration capability.Recent studies have found that cerebral ischemia may activate neurogenesis in brains of adult mammals,and bring new hope for neural repair after ischemic brain injury.It is very necessary to fully understand the site of neurogenesis,process and neurogenesis after cerebral ischemia and its regulation mechanisms in adult mammals.

Objective To explore the clinical significance of experimental index in incomplete Kawasaki disease (iKD).Methods Eighty-eight cases of KD were reviewed,including iKD 36 cases (iKD group),complete KD(cKD) 52 cases (cKD group).The 88 cases were divided into traditional criterion group (43 cases) and supplement criterion group (45 cases).The experimental indexes of supplement criterion were compared between iKD group and cKD group.Results The rate of coronary artery lesion (CAL) in iKD group was significantly higher than that in cKD group [50.00％(18/36) vs.26.92％(14/52),P ＜ 0.05].Plasma NT-proBNP and cardiac troponin Ⅰ (cTnI) in CAL children (32 cases) in early were significantly higher than those in non CAL children (56 cases) [(468 ± 141) ng/L vs.(379 ± 120) ng/L and (0.95 ±0.22) μg/L vs.(0.49 ±0.15) μg/L,P ＜0.01].The diagnosis rates of KD in the 5th,7th,9th day in supplement criterion group were significantly higher than those in traditional criterion group [64.44％(29/45)vs.25.58％(11/43),84.44％ (38/45) vs.46.51％ (20/43),93.33％(42/45) vs.58.14％ (25/43),P ＜ 0.01].There was no statistical significance between iKD group and cKD group in C reactive protein,erythrocyte sedimentation rate,albumin,alanine aminotransferase,platelet,white blood cell,NT-proBNP and cTnI etc (P ＞ 0.05).There was no statistical significance between iKD group and cKD group in the positive rate of each experimental index (P ＞ 0.05).Conclusions There are some changes of supplement experimental index in acute phase of KD,but there is no statistical significance between iKD and cKD.Plasma NT-proBNP and cTnI are significantly higher in early KD.

OBJECTIVE: To observe the effects of ginkgolide (GL) on the cerebral blood flow in dogs. METHODS: Dogs anesthetized with sodium pentobarbital were randomly divided into 5 groups, with 4 dogs in each group. Ginkgolide of 4.86, 14.6 and 43.7 mg/kg and Xingling Granule of 0.22 g/kg were administered by gavage to the dogs in each of 4 groups. The dogs in the other group were administered with edible oil (1 ml/kg) as control group. The cerebral blood flow, systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and electro-cardiogram of the dogs were measured at different times after the administration. RESULTS: Ginkgolide of 4.86, 14.6 and 43.7 mg/kg had no obvious effects on the blood pressure and the heart rate. Ginkgolide of 14.6 and 43.7 mg/kg increased the cerebral blood flow 90 minutes after administration, and ginkgolide of 43.7 mg/kg obviously decreased the cerebral vascular resistance 150 minutes after administration. CONCLUSION: Ginkgolide can increase the cerebral blood flow and decrease the cerebral vascular resistance, and it has no obvious effects on blood pressure and heart rate in dogs.
