Objective:To investigate the correlation between the expression of Golgi phosphoprotein 3 (GOLPH3) and the occurrence of apoptosis in colorectal cancer cells (CRC). Methods:Immunohistochemical assays of GOLPH3 and caspase-3 were performed on the paraffin-embedded sections of 62 CRC samples using the standard streptavidin-peroxidase technique. The apoptotic index of the CRCs was examined using the in situ terminal deoxynucleotidyl transferase nick-end labeling technique. The relationship of the GOLPH3 expression, the cell apoptosis, and the clinicopathologic parameters was analyzed. Results:The positive rates of GOLPH3 expression were significantly higher in the CRC tissues (53.2%) than in the normal colorectal mucosa (37.2%;P<0.05). Likewise, GOLPH3 expression was significantly higher in poorly differentiated cancer tissue, tissue outside the serous membrane, metastatic lymph node tissue, and the stage III CRCs, as compared with those of the moderately to well differentiated tissue, tissue inside the serous membrane, lymph node tissue without metastasis, and the stage I to II CRCs (P<0.05). However, GOLPH3 expression was not significantly correlated with the other clinicopathologic pa-rameters, namely, the age and sex of the patients as well as the site, depth, and length of the invasive tumor (P>0.05). The caspase-3 expression and apoptotic index were significantly lower in the GOLPH3-positive CRC tissue than in the GOLPH3-negative tissue (P<0.05). GOLPH3 expression was negatively correlated with the apoptotic index of CRCs based on the Spearman correlation (r=-0.320, P<0.05). Conclusion:GOLPH3 overexpression in CRC tissue is negatively correlated with apoptotic index.

Objective To evaluate the effect of YunKe on bone metabolism of patients with rheumatoid arthritis (RA). Methods A total of 108 RA patients were divided into YunKe group (n = 72), non-YunKe group (n = 36), and 54 controls. The bone mineral densities (BMDs) of the wrists, hips and lumbar spines were measured by dual-energy X-ray absorptiometry. Moreover , the expression of cross-linked N-telopeptides of type I collagen (NTX) in the serum was detected for statistically analyzing the difference between YunKe group and non-YunKe group. Results In RA group, the BMDs of wrist, hip and lumbar spine declined compared with that of control group (P < 0.001, respectively). In YunKe group, the BMDs of wrist, hip and lumbar spine after 6 months all were improved with statistically significance (P < 0.01, respectively); The differences also were statistically significant when compared with those in non-YunKe group (P < 0.01, respectively). In YunKe group, NTX level in the serum declined after 3 months of the treatment. The difference was statistically significant when compared with that in non-YunKe group (P < 0.001), but the difference disappeared 6 months later. Conclusions The BMD of wrist joints is low and declines in RA patients significantly. The treatment withYunKe improves the BMDs of the wrist , hip and lumbar spine and decreases the serum NTX. This study proposed that YunKe could inhibit the chronic loss of bone mass induced by RA.

BACKGROUND:There was no effective method to thoroughly treat tibial bone defect and soft tissue defect. The application of Ilizarov technique solved shortening deformity, soft tissue injury and joint contracture to some degrees.
OBJECTIVE:To discuss the effects of Ilizarov external fixation on treatment of tibial bone defect and the parameter selection of Ilizarov steel ring.
METHODS:We retrospectively analyzed the clinical data of 67 patients with tibial bone defects, who were treated and fol owed up from March 2007 to January 2012. Al patients had fracture of tibia and received one-stage operation. After treatment, postoperative limb suffered from tibia osteomyelitis and soft tissue injury. Ilizarov external fixation was placed in the limb. The length of defected tibia and area of defected soft tissues were compared at 1, 3 and 6 months after external fixation and final fol ow-up. The ankle joint Kofoed score and knee joint ROM score were observed before and after external fixation. In final fol ow-up, functional recovery was evaluated in accordance with diagnosis and treatment criteria of Johner-Wruhs fracture of shaft of tibia.
RESULTS AND CONCLUSION:A total of 67 patients were fol owed up for 6 to 35 months. Bone defects in 67 cases were rebuilt and the fracture was healed, but five cases had poor healing. Among 44 cases of soft tissue injury, wound had healed in 40 cases, and wound had not healed in 4 cases. The length of tibia defect and the area of soft tissue defects were improved at 1, 3, and 6 months after the operation (P<0.05). After operation, the ankle joint Kofoed score and knee joint ROM were significantly better than those before operation (P<0.05). During final fol ow-up, the excellent and good rate of each therapeutic plan was 85%. For the tibial osteomyelitis bone defect with the merged skin defect, the trauma was smal using Ilizarov technique, which can avoid several complicated operations, shorten the time and reduce the expenses of treatment, but there were some weaknesses and limitations. The size and material of Ilizarov external fixation affect the efficiency of the fixation and postfixation adjustment.

Objective To analyze the mammographic findings of triple-negative breast cancer [TNBC,which is estrogen receptor (ER) negative,progesterone receptor (PR) negative,and human epidermal growth factor receptor 2 ( HER2 ) negative ] and triple-positive breast cancer ( TPBC,which is ER positive,PR positive,and HER2 positive ),and to evaluate the relationship of immunohistochemologic receptor status and mammographic findings.MethodsThe immunohistochemistry results of 631 cases with breast cancers were reviewed,including 117 cases of TNBC and 44 cases of TPBC.All of the patients took mammography at initial diagnosis.We retrospectively evaluated the visibility,morphology,distribution and size of the lesion (masses and calcifications) and breast density on mammography of TNBC,and compared them with those of TPBC.The age onset and tumor sizes of TNBC and TPBC were compared by using Chi-square test and t test.ResultsThe visibility rate of TNBC and TPBC on mammography were 88.0%(103/117) and 90.9% (40/44),and the difference between them was insignificant ( x2 =0.055,P >0.05).TNBC was more frequently associated with merely a mass (56/103) than TPBC (12/40) (x2 =6.860,P<0.01 ),and the mean diameter of the mass of TNBC [ ( 2.6 ± 1.4 ) cm ] was larger than that of TPBC [(2.0 ± 0.6) cm](t =2.087,P < 0.05). TNBC were less frequently associated with microcalcifications (37/103) than TPBC ( 24/40 ) ( x2 =7.423,P < 0.01 ).Mammographic density and lesion visibility were similar between the two different immunophenotypes of breast cancers.The mean age of TNBC (52±9) was more than that of TPBC (48 ±8) (t =2.759,P <0.01).Infiltrating ductal carcinoma was the main pathologic type of both groups.Basal-like breast cancer accounted for 49% (57/117 ) of TNBC while none happened in TPBC.ConclusionsTNBC shows merely a mass with indistinct margins,lager size and is less associated with microcalcifications.These mammographic features might be useful in diagnosing triple negative breast cancer.
