Methods To remove 36 cases of different infiltrated-growth large or huge sellar region tumors by interhemisphefic approach microsurgery. Results In the 36 cases, total removal was achieved in 29, subtotal in 5 and most-partly in 2, and without any severe complications or death occured. 12 in 18 functional pituitary adcnoma were followed up, 10 cases got recovery on hormone level, and the level in 2 cases reduced ob ously. 2 cases recurred, both received γ-knife treatment. Conclusion The new interhemispheric approach surgery is important for large or huge invasive sellar region tumor.

Objective To investigate muli-leaf collimator (MLC)-defined small field output factors calculated by the treatment planning system (TPS), and to study the measuring method of small field output factors verified by 0.015 cc PinPoint ionization chamber.Methods Eight medical accelerators for intensity-modulated radiation therapy (IMRT) were investigated in Henan province, and TPS-calculated output factors for various small fields (6 cm ×6 cm,4 cm ×4 cm,3 cm ×3 cm and 2 cm ×2 cm) were compared with published values recommended by IAEA.If the relative deviation was more than ± 3％ for the 2 cm ×2 cm field size and ±2％ for the fields of 6 cm ×6 cm, 4 cm ×4 cm and 3 cm ×3 cm, which was beyond the scope of IAEA allowed, the output factors will be measured and verified using 0.015 cc PinPoint ionization chamber and Unidos electrometer.Results TPS-calculated small field output factors for eight medical accelerators were compared with published values.The relative deviation of small field output factors for five pieces of equipment, which accounted for 62.5％ of the total, met the IAEA's requirement, while the other three, which accounted for 37.5％ of the total, did not.After measuring with PinPoint ionization chamber, the results from only three pieces of equipment met minimum IAEA's requirement.Conclusions MLC-defined small field output factors calculated by TPS for some medical accelerators in Henan need to be measured and corrected using micro-ionization chamber, and the measured values could be taken as the basis of radiation treatment planning.

ObjectiveTo establish a method of rapid detection of bacteria endotoxin based on interdigital gold electrode and surface acoustic wave (SAW).MethodsWith the carriers of 3-APTES and glutaral pentanedial,Polymyxin B (PMB) was immobilized on interdigital gold electrode,and then reacted with the bacteria endotoxin' s biological active material (lipopolysacchride,LPS) selectively.Double differential circuit based on SAW was employed to complete the detection.Two output oscillation signals were differentiated through mixer and the endotoxin content was described by frequency shift.ResultsThe experimental results indicated that there was a liner relationship between the frequency shift and endotoxin content within the content range of 75-130 EU/ml.ConclusionComparing with traditional method,the detection time is shortened to 10 minutes,the sensitivity is 13.8 KHz/(EU·mL-1),and repeatability is above 90％.

Objective To study expression and significance of keratin 17 and 19 in psoriatic lesion.Method The expression of keratin 17 and 19 in 30 psoriatic lesion and 10 normal skin was measured by immunohistochemistry method.Results The expression level of keratin 17 in the psoriatic lesion was higher than that in the normal skin,the expression level of keratin 19 in the psoriatic lesion was lower than that in the normal skin,there were significant differences in the expression of keratin 17 and 19 between them(P ＜0.05).The optical density level of keratin 17 in the psoriatic lesion was obviously raised compared with the normal skin(5.81 ± 1.42 vs.0,P＜ 0.01).The optical density level of keratin 19 in the psoriatic lesion was obviously decreased compared with the normal skin(0.49 ±0.03 vs.2.03± 1.08,P＜0.05).The optical density level of keratin 17 and 19 showed negative correlation in the psoriatic lesion(r =-0.479,P＜ 0.01).Conclusion Keratin 17 and 19 may play a role in the pathogenesis of psoriasis.

Objective To investigate the effects on knee function between patella plasty and patellar replacement in total knee arthroplasty.Methods From August 2010 to November 2010,48 patients (69 knees) of osteoarthritis performed TKA were covered in this study.All the patients were randomly assigned to the following two groups:one group contained 24 patients (34 knees) performed patella plasty,and the other group contained other 24 patients (35 knees) performed patellar replacement.There was no significant difference between the two groups in age,weight,height,BMI,patellar score and the American Knee Society Score (KSS).Every patient was followed up for 6 weeks,3 months,6 months,one year,and two years.All the results,which were used to compare the difference between the two groups,in KSS knee score,knee function score,patellar score,the incidence of anterior knee pain,and imaging findings.Results In this clinical study,20 patients (30 knees) in patellar replacement group and 20 patients (29 knees) in patella plasty group were followed up.No significant difference was found in the postoperative KSS knee score between 2 groups at each time point.The KSS knee function score in replacement group was significantly higher than that in arthroplasty group at 6,12 and 24 months after operation.The incidence of anterior knee pain after the surgery in replacement group was significant different from the plasty group at every time point after operation.There was no significant difference in tibiofemoral angle,patellar ligament ratio,patellar tilt angle,congruence angle and lateral patellar displacement between two groups at last follow-up.Conclusion Total knee arthroplasty with patella replacement can improve both knee function and patella function,and reduce the incidence of postoperative anterior knee pain.

Seven of the 12 family members were heterozygous for the IVS- Ⅱ-654 (C→T) mutation. The abnormal ? gene of proband was confirmed from the paternal side according to family survey, clinical syndrome and hematological data.

Innate lymphoid cell is a type of newly discovered innate immune cell , which can function as adaptive T cells . Based on the transcription factors and the expression of effector cytokines , innate lymphoid cells can be categorized into three sub-groups:ILC1, ILC2 and ILC3.The inflammatory factors these produced by ILC play an important role in the development of inflamma -tory bowel disease (IBD), but ILC3 can secrete IL-22, which promotes the restoration of intestinal epithelial cells .Exploring the func-tion of ILC has a great significance in the treatments of IBD .This article reviews their phenotype , function and also relationship with IBD.
