Objective To evaluate the clinical value of bronchoscopy lung biopsy Combined with brush cytology .Methods Collected 113 cases of diffuse or clinical cases of peripheral pulmonary disease examined by bronchoscopy lung biopsy Combined with brush cytology with no X-ray guiding during January 2011 to December 2012 .And the inspection results and the corresponding clini-cal data were retrospectively analyzed.Results In 113 cases 73 cases made a definite diagnosis, diagnostic positive rate was 64.60% in total, include 96.02% of diffuse patchy shadows, 72.13% of diffuse millet or nodular, 54.12% of local infiltration fo-cal, 32.11% of diffuse grid or ground glass honeycomb lesion, 28.26% of local tumor nodules.Conclusion There is significantly clinical diagnosis value of bronchoscopy lung biopsy Combined with brush cytology to examine diffuse and peripheral pulmonary dis-ease.

Because articular chondrocytes have a long-term exposure to different degrees of hypoxic environment , hypoxia induc-ible factor is considered to be one of the most important regulation factors to adapt to low oxygen levels .It plays a significant role in the metabolism, repair, and degeneration of cartilage chondrocyts .This article reviews the comprehensive effects of hypoxia inducible fac-tor in cartilage chondrocyts .

Objective Uncemented prothesis has become the preference of first hip arthroplasty, but there is a little study on its application in cemented acetabular revision arthroplasty.This paper aimed to evaluate the clinical effects of uncemented acetabular cup in cemented acetabular prosthesis revision arthroplasty. Methods A retrospective analysis was made on the clinical data of 31 patients(31 hips) who underwent revision arthroplasty using uncemented acetabular prosthesis from January 2012 to March 2015.Har-ris hip score( HSS) was applied to measure the hip function and visual analogue score( VAS) was preformed to assess the pain degree of knee joint preoperatively and postoperatively(3 months, 6 months and 1 year).All the patients were followed up for a mean of 22 months ranging from 3 to 42 months. Result The mean HSS increased from preoperative points (53.19 ±9.12) to postoperative points([77.71 ±5.75]at 3 months,[80.61 ±5.74] at 6 months,[82.94 ±5.80] at 1 year ).The mean VAS score decreased from preoperativepoints (6.23 ±1.23) to postoperative points(0.26 ±0.27).No lossening, infection or deep vein thrombosis were found in the patients′prostheses. Conclusion For patients with PaproskyI-Ⅱ acetabular defects, uncemented acetabular prosthesis has satisfactory short-term clinical results in revision arthroplasty with cemented acetabular prosthesis, however, long-term clinical results remain to be further observed.

Bone marrow from 20 patients suffering from aplastic anemia were cultured with fetal muscle condition medium and in three different combinations: (1) Marrow from the patients cultured alone; (2) Coculture of marrow from patient with normal marrow; and (3) Culture of normal marrow with serum from patient. It was found that: (1) Nine patients had low colony formation when culture alone; no suppression in coculture and no inhibiter factor was found in serum from patient. Stem cells might be absent or defective in these patients. (2) Five patients had low colony when cultured alone; their marrow showed marked inhibitory effect on normal marrow CFU-C in coculture. and the latter was decreased by 40-100%. Suppressor cells might have caused the aplasia in these patients. (3) The sera from five patients suppressed CFU-C of normal marrow cells, colony counts being decreased by 55-77%. The cause of aplasia in these patients might be the presence of an humoral inhibiting factor. (4) In one patient no abnormal findings were found in all three different combinations of cultures. This patient might be suffering from a defective hematopoietic environment.
