[Objective]To discuss the outcome of acetabular protrusion after total hip arthroplasty. [Method]Fifteen patients(M=7,F=9) having painful acetabular protrusion received total hip arthroplasty with reinforcement of the acetabulum with bone grafts(autogenous or allogeneous bone).The results were reported at 1~4 years(mean,3 years) of follow-up.Of the 15 cases,5 were mild protrusion and 10 were moderate protrusion.The Harris hip-rating and radiographs were taken pre-and postoperatively. [Result]The average Harris hip-rating was improved from 45 points(range,39~60 points) preoperatively to 85 points(range,70~100 points) postoperatively.The average preoperative protrusion of the femoral head medial to the Kohler line was 8.8 mm(6~18 mm).The average postoperative placement of the prosthetic femoral head was 10 mm(6~13 mm) lateral to the Kohler line.None acetabulum prothesis failure or bone grafts absorption was seen.The grafts were well incorporated on radiograms in all patients one year after operation by radiographs. [Conclusion]Good results can be obtained in hips with acetabular protrusion after reconstructed with autogeneous or allogeneous bone grafting and total hip arthroplasty.

As a transmembrane protein, CD47 is widely distributed in a variety of cells. It can bind to signal regulatory protein alpha (SIRPα) on macrophages and release inhibitory signals, thus avoiding phagocytosis of macrophages. In lymphoma cells, the expression of up-regulation of CD47 expression in lymphoma cells is one of the important mechanisms for inducing immune escape, and it is also a potential therapeutic target. This article reviews the research progress of CD47-induced immune escape, monoclonal antibodies targeting CD47 and cellular immunotherapy in the treatment of lymphoma.

Traditionally the mast cell has been known to he a cell component dwells in annective tissue. But oocasional epithelial mast cells were presented both in light microscopic and electron microscapic examinations. This study was undertaken to evaluate the presence of mast ceil in epidermis of diseased skin. A total of 93 biopsy specimes obtained from the skin lesions of patients with various dermatological conditions were examined with light microacope after toluidine blue stain. The results are as follows: 1. Mast cells were shown in the epidermis of 2 patients with chronic eczema and one patient with pustular psoriasis. 2. Most of the epidermal mast cells were located in ar nearby the basal ceII layer. 3. Epidrmal mast cells have an oval or round nucleus and variable amounts of granulesin the cytoplasm. Some of the cells have a halo-like clear zone around them.

Bacteriological index(BI) was calculated by slit-skin smears taken from the earlobe and the dorsal surfaces of the proximal phalanges of the index finger and of the great toe in 110 lepromatous leprosy patients who have been treated regularly by antileprosy chemotherapy. The bacteriaI indices from the three sites were compared, and the results were as follows. 1) Sixteen patients whose BI of the earlobe smear was 4. 0 in average shawed the highest degree of positivity of M. leprae in the smears taken from the finger and the great toe. 2) ln seventy-four patients whose BI of the earlobe smear was l. 0 or higher, eight (10.8%) showed higher BI in smears taken from both the finger and the great toe, fifteen (20. 3%) and twenty-seven(36. 5%) showed approximately the same BI in smears taken from the finger and the great toe, respectively, 3) In thirty-six patients whose BI of the earlobe smear was negative, twelve (33. 3%) showed higher BI in smears taken from both the finger and the great toe. 4) The mean value of BI of the three sites was 3.7 in the earlobe, 3. 2 in the finger and 3. 0 in the great toe. Comparing the BI of the three sites, the finger and the great toe were found to have comparable BI with the earlobe, although the BI of the earlobe was highest. The authors concluded that it was quite reasonable to include the finger and the great toe in slit-skin smears for M. leprae identification, particularly when the BI of the earlobe was negative. A follow-up investigation seems mandatory.
