BACKGROUND:Orthotopic lung transplantation model in a rat is the key to investigate the chronic rejection after lung transplantation. However, the precise surgical technique and difficult operation limit the application of the model. OBJECTIVE:To improve the process of anesthesia and lung transplantation, and to establish a rapid, safe and reversible rat lung transplantation model. METHODS:A total of 42 rats were used to establish the model, including 21 donor models and 21 receptor models. The donor lung was excised by median sternotomy with dissection of the left lung and implantation of cuffs (intravenous catheters cut into 1.5 mm sections). The left lung was implanted in the recipient by lateral thoracotomy using the cuffs for anastomoses. The duration of surgery and success rate of transplantation were recorded and calculated. RESULTS AND CONCLUSION:The survival rate of rats after lung transplantation was 100%. The time of left donor lung extraction was (35.3±5.1) minutes in average. The time of placing cuff in donor lung was (12.5±4.6) minutes in average. The surgical procedure time of recipient was (50.2±3.3) minutes. The time of arteriovenous and bronchus casing anastomosis was (27.7±6.2) minutes. After pulmonary artery and vein blood flow was disparked, the whole lung turned red rapidly, blood perfusion was sufficient, venous returned unimpeded;after mechanical ventilation resumed, al graft lungs expanded wel . This improved anesthesia and lung transplantation technique in rats can provide a valid, reliable and reproducible animal model for studying immune responses and rejection in lung transplantation.

Objective To observe the efficacy of percutaneous vertebroplasty (PVP) combined with zoledronic acid in treatment of spinal metastatic carcinoma.Methods Fifty cases of spinal metastatic carcinoma were divided into control group and treatment group by random digits table method with 25 cases each.The control group was given zoledronic acid 4 mg,intervals of 28 d intravenous drip 1 time.The treatment group was given PVP besides zoledronic acid.The visual analog scale score,activity ability score and analgesic usage score after treatment for 3 months were observed and compared.The quality of life was evaluated and the occurrence of relapse of fracture was also recorded.Results After treatment for 3 months,the visual analog scale score,activity ability score and analgesic usage score were (2.00 ± 0.17),(2.12 ± 1.38),(1.47 ± 0.10) scores in treatment group,and (7.84 ± 0.18),(3.21 ± 0.13),(3.30 ± 0.09) scores in control group,and there were significant differences between two groups (P ＜ 0.01 or ＜ 0.05).The occurrence of relapse of fracture was 2 cases (8％,2/25) in treatment group and 9 cases (36％,9/25) in control group,and there was significant difference between two groups (P ＜ 0.05).Conclusions PVP combined with zoledronic acid in treatment of spinal metastatic carcinoma has many advantages such as small incision,short surgery time and rapid relief from pain.It can obviously improve the quality of life,and it is worthy of spreading in the clinic.

Objective:To investigate the expression of microRNA-324-5p (miR-324-5p) and transcription factor forkhead box C1 (FOXC1) in glioma and their relationship with the prognosis of patients.Methods:From March 2012 to March 2015, a total of 72 cases of glioma tissues were collected from glioma patients who were admitted to Chongqing Hygeia Tumor Hospital and the People's Hospital of Nanchuan in Chongqing, and 28 cases of normal human brain tissues resected in craniocerebral surgery were also collected. The expressions of miR-324-5p and FOXC1 mRNA were detected by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR), and the expression of FOXC1 protein was detected by immunohistochemistry. Pearson method was used to analyze the correlation between the expressions of miR-324-5p and FOXC1 in glioma tissues; Kaplan-Meier method was used to analyze the survival of patients with glioma; Cox regression analysis was used to analyze the risk factors affecting the prognosis of patients with glioma.Results:FOXC1 protein was mainly located in the cytoplasm of glioma, and its positive expression rate in glioma tissues was 81.94% (59/72), which was significantly higher than that in normal brain tissues [17.86% (5/28)], and the difference was statistically significant ( χ2 = 35.938, P<0.01). Compared with normal brain tissues, the expression of miR-324-5p was down-regulated in glioma tissues (0.62±0.19 vs. 0.98±0.02, t = 9.974, P < 0.05), and the expression of FOXC1 mRNA was up-regulated (1.41±0.29 vs. 0.99±0.02, t = 7.633, P < 0.05). The expressions of miR-324-5p and FOXC1 protein were correlated with the number of primary lesions, differentiation degree, TNM stage and lymph node metastasis of glioma (all P<0.05). Pearson analysis showed that the expressions of miR-324-5p and FOXC1 mRNA were negatively correlated ( r = -0.550, P<0.01). The 5-year overall survival rate of patients in miR-324-5p high-expression group was significantly higher than that of patients in miR-324-5p low-expression group (45.71% vs. 24.33%, χ2 = 6.531, P = 0.011), and the 5-year overall survival rate of patients in FOXC1 protein high-expression group was significantly lower than that of patients in FOXC1 protein low-expression group (30.41% vs. 42.34%, χ2 = 3.631, P = 0.047). Multivariate Cox regression analysis showed that low differentiation, TNM stage Ⅲ-Ⅳ, lymph node metastasis, low expression of miR-324-5p and high expression of FOXC1 protein were independent risk factors for prognosis of glioma patients (all P < 0.05). Conclusions:The expression of miR-324-5p is low and the expression of FOXC1 is high in glioma. They may be involved in the regulation of tumor differentiation and metastasis, and related to the poor prognosis of patients. They may be potential therapeutic targets for glioma.

This paper analysed the rhinoscope's clinical value in microsurgical treatment of intracranial aneurysms. Application of the rhinoscope in 87 patients, only 2 patients had ruptured during operation. However, 11 cases had ruptured in 94 cases without using rhinoscope, P < 0.05, they had a significant difference. By DSA follow-up review, 82 cases of used rhinoscope only 2 cases had remained the aneurysm neck, but 9 cases had the aneurysm neck in 77 cases which had not used the rhinoscope in the microsurgical treatment, P < 0.05, they also had significant difference. The application of rhinoscope in microsurgical treatment of intracranial aneurysms intraoperative, can reduce the risk of the intraoperative aneurysm rupture. It can achieve better clinical effect.

A bacterial strain DN25, effective on cyanide-degradation, was isolated from contaminated soil and identified as Alcaligenes sp. on the basis of phenotype analysis and 16S rDNA sequence analysis. It showed great tolerance to the cyanide, which can grow in the medium containing 500mg CN -/L. The suitable condition for the cell growth and boitransformation was pH8.0 and 30oC and the transformation rate for 500mg CN - /L could achieve 99% in 10 h. It has also been found that the screened strain had the ability of K 4Fe(CN) 6 transformation with 96% of transformation rate at 12 h for the concentration of 500 mg CN /L.

BACKGROUND:It is important to maintain the height of joint line in total knee arthroplasty or renovation. Foreign scholars have reported the parameters of the distance from different landmarks to knee joint line, but there is stil a lack of relevant data for Chinese people. OBJECTIVE:To explore the relationships of the knee anatomic landmarks and joint line in normal Chinese, thereby providing clinical evidence for primary total knee replacement and knee renovation. METHODS:Totaly 746 normal knee joints of 409 healthy volunteers from North China and Southwest China were randomly enroled, including 214 males and 195 females, with a mean age of 37.7 years. CT scan was used to reconstruct the three-dimensional knee joint, and the distance between the anatomic landmarks and the joint line was measured using Mimics software. RESULTS AND CONCLUSION:The distance from the center of femoral medial sulcus to the joint line was (25.72±2.52) mm. The distance from the center of lateral femoral condyle prominence to the joint line was (26.30±2.65) mm. The distance from the adduction muscle tubercle to the joint line was (44.60±4.32) mm. The distance from the peak of the tibial tubercle to the joint line was (21.50±3.57) mm. These parameters in male group were significantly higher than those in female group (P < 0.05). In conclusion, these findings provide anatomic evidence for the recovery of joint line in knee replacement or renovation; the variability of the distance from the center of femoral medial sulcus, lateral femoral condyle prominence and adductor tubercle to the joint line is smaler, and therefore, these landmarks have more reference values in total knee arthroplasty.

OBJECTIVETo investigate synergistically killing effect of histone deacetylase (HDAC) inhibitor suberoylanilide hydroxamic acid (SAHA) combined with imatinib on human chronic myeloid leukemia (CML) cell line.

METHODSK562 cells were co-treated with SAHA and imatinib. Cell growth was measured by MTT assay. Apoptosis was determined using Hoechst staining apoptosis detection kit and flow cytometric analysis. Activation of Caspase pathway, expression of Bcr-Abl and its downstream target genes, and expression of anti-apoptotic proteins were detected by Western blot.

RESULTSSAHA synergized the cytotoxicity of imatinib against leukemia K562 cells, concomitantly with increased apoptosis and enhanced activation of Caspase-3, -8 and PRAP. The combination therapy resulted in significantly lower levels of Bcr-Abl,phosphorylated Bcr-Abl compared to treatment with either SAHA or imatinib alone. Furthermore,the co-treatment resulted in down-regulation of anti-apoptotic protein Mcl-1 expression. Also,marked down-regulated expression of JAK2,STAT5,and phosphorylated STAT5 was detected in the combination therapy.

CONCLUSIONCombining HDAC inhibitor SAHA with imatinib can kill CML cells synergistically by inhibiting cell growth and inducing apoptosis, which is associated with activation of Caspase pathway and regulation of anti-apoptotic proteins.
