Objective The diabetic foot ulcer has high incidence rate,many complications,and is difficult to heal.Methods We summary the treatment expericncc of 156 cases of diabetic foot wounds.On the basis of comprehensive standard medical treatment,according to the wound characteristics,blood supply,and the degree of tissue necrosis,we performed staging gnawing-away debridement for all tbe wounds,combining with pressure suction,new dressing,skin grafts and skin flaps.Results Of all the 156 cases,2 cases died,4 cases were lost to follow-up,the remaining 150 cases healed,with an average time of 56 days.Conclusions The treatment of diabetic foot ulcer must take into account both the systemic therapy and local processing,the wound should be debrided with different stage and progressively.When the wound microenvironment is gradually improved,it can be covered appropriately with skin grafts.The skin flap should be chosen cautiously.

Objective To investigate the relationship between the expressions of proliferating cell nuclear antigen (PCNA), p53 and Bcl-2 protein and clinical chemothreapy, prognosis in bone marrow cells in children with acute leukemia (AL). Methods Immunohistochemical SP method was used to detect the expressions of PCNA, p53 and Bcl-2 in specimens of bone marrow puncture of 59 children with AL and 15 healthy children as control. Results There was a significant difference in the expressions of PCNA, p53 and Bcl-2 proteins between the initially treated patients and healthy subjects, and between the remission patients and non remission ones. There was not a significnat difference in PCNA expression between the refractory patients and healthy subjects, and PCNA expression was related to the chemotherapeutic sensitivity. There was a significant difference in the 6-week remission rate between the patients with and without PCNA expression, but there was no significant difference in the over 3 years survival rate without illness. The expression levels of Bcl-2 and p53 were significantly higher in the refractory patients than those in healthy subjects. The patients with the high expression of p53 and Bcl-2 were resistant to chemotherapy, low in the remission rate and poor in prognosis. Conclusion The AL patients with PCNA expression were higher in remission rate, and PCNA expression was not associated with long-term prognosis. The AL patients with the expression of p53 and Bcl-2 were lower in remission rate, and their expression was associated with long-term prognosis. Both p53 and Bcl-2 protein may serve as a molecular marker to predict chemotherapeutic sensitivity and prognosis. PCNA, p53 and Bcl-2 may be involved in the pathogenesis of child AL by various ways. It is more valuable for predicting prognosis to simultaneously detect the expression of PCNA, p53 and Bcl-2 proteins.

Objective To analyze warfarin anticoagulation therapy for patients after heart valve replacement,and to explore an optimal intensity of warfarin anticoagulation.Methods The administration method,international normalized ratio (INR) monitoring of 265 patients who received warfarin anticoagulation therapy after heart valve replacement were analyzed retrospectively.The patients were divided into three groups according to different valve prostheses:aortic valve replacement (AVR) group (37 cases),mitral valve replacement (MVR) group (165 cases) and double valve replacement (DVR) group (63 cases).Each group was divided into two subgroups according to their INR levels (INR 1.5-2.0,INR 2.1-2.5).The occurrence of bleeding and thromboembolic events in these subgroups were compared.Results A total of 265 cases were visited,and followed up for 4 months to 6 years.The dose of warfarin was 0.625-7.500 (2.5 ± 1.4) mg/d.The incidence of anticoagulation adverse events was 23 cases.The incidence of bleeding events was 6.79% (18/265),which was higher than that of thromboembolic events (1.89%,5/265),and there was significant difference (P < 0.05).Four cases of the hemiplegia sequelae occurred and 2 cases died.The incidence of bleeing events in patients with INR1.5-2.0 in AVR group,MVR group and DVR group were 0 (0/20),3.57% (3/84),2.70% (1/37),in patients with INR 2.1-2.5 were 1/17,11.11% (9/81),15.38% (4/26),and there were significant differences (P < 0.05).There were no significant differences in the incidence of thromboembolic events between INR 1.5-2.0 and INR 2.1-2.5 in AVR group,MVR group and DVR group (P > 0.05).Conclusions After heart valve replacement,the anticoagulation therapy with warfarin is effective and safe to maintain the low intensity anticoagulation (INR1.5-2.0).AVR and MVR/DVR may benefit from a treatment strategy with levels ranging from 1.5-1.8 and 1.8-2.0,and the anticoagulation therapy of individuation should be formulated according to different conditions.

The potamon that were sold by Mengla market were examined positive for two species of paragonimus metacercariae andexcyted metac ercariae, this is the first report in Yunnan Province. The potamon that were sold by cities market from other suburbs may cause epdemic or outbreak of paragonimiasis, there is of momentous significance in epidemiology.

ObjectiveTo study the effect of SSY-B2 on regeneration of central nervous system of rats with bilateral fornix/fimbria transaction.MethodsMale adult SD rats were divided randomly into 6 groups as sham group,model group, positive control agent piracetam group, SSY-B2 low dosage(1.5g crude drug/kg) group, medium dosage(3g crude drug/kg) group and high dosage(6g crude drug/kg) group.The bilateral fornix/fimbria transection in the rats were carried out. After operation, drugs were fed introgastrically to each group respectively for 6 weeks. The immunoreactive products of growth-associated protein-43(GAP-43 )and chondroitin sulfate proteoglycans(CSPG) in defined areas were measured using immunohistochemical methods. ResultsThere was no difference in number of cells expressing GAP-43 between the model group and sham group (P>0.05),but that in low dosage group increased compared with the model group (P<0.001). The CSPG in parietal lobes after lesion expressed,which was in sham group and model group(sham group and model group respectively, 56.43±59.6,116.36±10.561), and SSY-B2 in low and medium dosage inhibited its expression compared with the model group (P<0.05,P<0.01). Conclusions SSY-B2 can enhance the expression of GAP-43 and inhibit the expression or deposition of CSPG, promote axonal regeneration in the CNS, and thus structural repair and functional restoration in certain degree.

ObjectiveTo evaluate the possible effect of SSY-B2 on reducing the loss of neurons and enhancing the expression of nerve growth factor(NGF).MethodsMale adult SD rats were divided randomly into 6 groups as sham group,model group,positive control agent piracetam group, SSY-B2 low(1.5g crude drug/kg), medium(3g crude drug/kg)and high dosage (6g crude drug/kg)group.Bilateral fornix/fimbria transection was carried out in the rats' septohippocampal pathway and 6 weeks' drug treatment was administered with different doses of SSY-B2 and positive control agent piracetam. After behavioral tests, the numbers of neurons in medial septum and immunoreactive products of NGF in different areas were measured, using Nissle staining and immunohistochemical methods.ResultsThere was neural loss in medial septum after fornix /fimbria transection, but SSY-B2 at each dosage markedly reduced the loss(59.13±22.02,50.60±23.18,63.93±18.35,the number of neurons for three SSY-B2 dosage groups,P<0.005 for all compared with the model group 20.33±14.01).The number of NGF positive cells decreased in model group, but did not show significant statistic difference compared with the sham group (P>0.05) in the medial septum, polymorph layer of dentate gyrus and entorhinal cortex/Subiculum area. In the medial septum, all three dosage enhanced the expression of NGF positive cells(145.1±57.7,161.3±08.2,200.6±58.2,the number of neurons for three SSY-B2 dosage group,P<0.005 for all compared with the model group 50.2±48.6). SSY-B2 at low and medium dosage group also increased the number in both entorhinal cortex/Subiculum and polymorph layer of dentate gyrus.Conclusions SSY-B2 can reduce the loss of neurons in the medial septum, which may be involve in increasing expression of NGF;NGF expression in dentate gyrus, subiculum of hippocampal formation and entorhinal cortex increased by SSY-B2 may play a role in the compensation of these area for learning/memory.
