Objective To evaluate the effect of olecranon osteotomy and triceps pedicel approach combined with ossylated triol in the treatment of humeral intercondylar fracture and its effect on prognosis. Methods Ninety-two patients with humeral intercondylar fractures were selected as study subjects. The patients were randomly divided into two groups: the study group and the control group. The study group selected the olecranon osteotomy for treatment. The control group selected brachial Triceps tongue tongue approach for treatment. Results The excellent and good rate of the study group was significantly higher than that of the control group (P<0.05). The mean time of operation and the time of fracture healing were significantly higher than those of the control group (P<0.05), and The data of PLT, ESR, CRP and RF in the two groups were significantly lower than those in the control group (P<0.05) , and the data of inflammatory indexes in the study group were significantly decreased (P<0.05).Conclusion The treatment of humeral intercondylar fractures with olecranon osteotomy combined with calcitriol has a direct effect. It can be seen that this treatment has a high value in clinical orthopedic treatment.

Gastrointestinal tumor patients are characterized by malnutrition resulting from various elements. So it is necessary to analyze,assess, and treat malnutrition of patients with gastrointestinal tumor. Nutrition support is an indispensable step in tumor therapy.

Background Research comfirmed that second mitochondrial activator of caspase (Smac) is a promoting tumor cell apoptosis protein.Our previous study showed that the expression level of Smac in LECs is obviously higher in cataract than that in normal eyes.We assumed that silencing Smac gene in LECs can inhibit the apoptosis of LECs.The way to transfect Smac siRNA into LECs is a key step.Objective This study was to construct siRNA lentiviral vector of Smac and identify its silencing efficiency in human lens epithelial B3 cell line (HLE-B3) and establish low-expressed Smac HLE-B3 line.Methods Based on the genebank and our previous study,siRNA sequence of Smac was designed and composed.The synthetic double-stranded DNA was linked to the lentiviral vector GVll8 by T4 DNA ligase and then transformed DH5α competent cells.The plasmids were transformed into the DH5α competent cells.Recombinant colonies were screened by PCR and sequenced.Recombinant plasmids and two other auxiliary plasmids were used to infect 293T cells.Cell culture supernatant was collected for the measurement of viral titer.Recombinant lentiviral vector was used to infect HLE-B3 cells to calculate the viral multiplicity of infection (MOI) under the fluorescence microscope.Transfection efficiency was examined by calculating the GFP-positive cells.HLE-B3 cells were divided into negative control group,siRNA plasmid tranfected group and GV118-Smac-siRNA1 tranfected group.The relative expression levels of Smac mRNA in the cells were detected and compared among the three groups by real-time fluorescent quantitative PCR.Results GV118-Smac-siRNA was successfully constructed with the positive colonies 340 bp and blank vector colonies 299 bp,and viral titer was 3.0× 108 TU/ml.At a MOI of 100,the infecting efficiency of the vector on HLE-B3 cells was about 82％ and the cytotoxicity was low.The relative expression levels of Smac mRNA were (101.290±8.349)％,(92.330±6.320)％ and (32.540±4.221)％ in the negative control group,siRNA plasmid tranfected group and GV118-Smac-siRNA1 tranfected group,respectively,showing a significant difference among the three groups(F =32.871,P＜0.01),and the relative expression level of Smac mRNA was significantly lower in the GV118-Smac-siRNA1 tranfected group than that in the negative control group (P =0.000).However,no significant difference was found in the Smac mRNA expression between the blank plasmid group and the negative control group (P=0.535).Conclusions GV118-Smac-siRNA lentiviral vector is successfully constructed.Smac-siRNA can effectively inhibit the expression of Smac mRNA in human LECs.

Objective To study the clinical efficacy of Akin combined Scarf osteotomies for moderate and severe hal?lux valgus. Methods Thirty-nine (58 feet) patients received Akin combined Scarf osteotomies, in which 12 patients (16 feet) with moderate hallux valgus received the single scarf osteotomy. Hallux valgus angle (HVA), intermetatarsal angle (IMA), tibial sesamoid position and American orthopedic foot and ankle society score (AOFAS) were measured and compared before and after operation respectively. Results All operations were successfully completed patients were followed up for 8-22 months. The mean operation time was (55.0±6.8) min. The amount of intraoperative bleeding was 3-20 mL with an aver?age of (11.0±5.4) mL. All patients were healed except for a delayed union of Akin on a severe hallux valgus patient. Two cas?es (2 feet) were found inflammation in surgical incision. Two cases (2 feet) were found numbness in dorsal medial side of hal?lux, which was considered nerve damage and improved in 3-5 months. There was no recurrence of hallux valgus in the peri?od of following up. After surgery, HVA (14.1°±5.3°), IMA (7.7°±3.8°) and tibial sesamoid position (2.58±0.61) were signifi?cantly decreased compared with those before operation (39.6° ± 6.8° , 18.7° ± 5.4° and 4.87 ± 0.59, P<0.05). AOFAS score (84.4±8.7) was significantly higher after surgery than that before surgery (37.3±9.5, P<0.05). Conclusion Akin combined Scarf osteotomies can achieve a excellent therapeutic effect for moderate and severe hallux valgus with very few complica?tions and recurrence, which is worth for clinical application.

Purpose To evaluate the value of multi-slice spiral computed tomography (MSCT) scan in the diagnosis of papillary renal cell carcinoma. Materials and Methods A retrospective study was conducted on the findings of plain CT scan and triphasic dynamic contrast enhanced CT scan of 23 patients with papillary renal cell confirmed pathologically, and further contrasted with the findings of 96 patients with clear cell renal cell carcinoma at corresponding phases in such aspects as cystic degeneration, enhancement degree and pattern (homogeneous, peripheral or heterogeneous) and tumor spreading pattern (perinephric invasion, lymphadenopathy or venous invasion). Results The degree of enhancement CT value for both diseases showed statistical significance in corticomedullary phase, parenchymal phase and excretory phase (t=9.70, 8.08, 5.92;P<0.01), but papillary renal cell carcinoma was lower than clear cell renal cell carcinoma. In terms of cystic degeneration, papillary renal cell carcinoma was significantly lower than clear cell renal cell carcinoma (21.7%vs 54.2%,χ2=7.54, P<0.01). Papillary renal cell carcinoma mainly showed homogeneous enhancement (60.9%) whereas clear cell renal cell carcinoma mainly presented heterogeneous enhancement (68.8%) with statistical difference (χ2=30.40, P<0.01). The tumor spreading patterns like perinephric invasion, lymphadenopathy and venous invasion had no significant difference (χ2=0.51, 0.11, 0.03;P>0.05). Conclusion Papillary renal cell carcinoma shows homogeneous enhancement, seldom cystic degeneration or necrosis on MSCT scan, which is helpful for the differential diagnosis from clear cell renal cell carcinoma.
