Objective To explore the association of expression of apoptosis-associated gene BAK and cFLIP with the biological behaviors in endometriosis. Methods The expression of BAK and cFLIP protein gene in eutopic and ectopic tissue samples from 40 cases with pathologically confirmed ovarian endometriosis and 40 cases with pathologically confirmed normal endometrium was detected by immunohistochemical method. Results ①The expression of BAK and cFLIP protein gene was found in three groups of different endometrial tissue. ②The expression of BAK protein gene was increased gradually in ectopic endometrial , eutopic endometrium and normal tissue and there was significantly difference between every two groups ,while cFLIP was contrary expressed (P <0.05); ③In normal endometrium, The expression of BAK protein gene in secretory phase was higher than that in proliferative phase (P < 0.05), while cFLIP was contrary expressed, in eutopic endometrium and ectopic endometrial tissue , The expression of BAK and cFLIP protein gene in secretive phase showed no statistically significant difierence with that in proliferative phase (P > 0.05). ④The expression of BAK protein gene in severe group (Ⅲ-Ⅳ period) is lower than mild group both in eutopic or ectopic endometrial tissues,while cFLIP was contrary expressed (P < 0.05). ⑤The expression of BAK and cFLIP was negatively correlated with each other in ectopic endometrium (r=-0.389,P< 0.05). Conclusion BAK and cFLIP was negatively expressed in EMS, which may take a part in the endometrial apoptosis and disorderly proliferation. BAK and cFLIP may play an important role in the the diagnosis and treatment of endometriosis.

Objective To investigate the relationship between the posttraumatic growth in cancer patients and patients' quality of life. Methods 123 cancer patients were measured with posttraumatic growth inventory (PTGI) and EORTC QLQ-C30. Means and standard deviations were used to describe the domain and the range change of posttraumatic growth. Correlation and multiple linear regression analysis were conducted to explore the relationship between the patients' posttraumatic growth and their quality of life. Results 4 of 5 factors in PTGI showed significant positive change, including connection with others [(28.17±7.97) scores], new possibilities [(16.15±6.06) scores], personal strength [(15.42±4.69) scores], and appreciation of life [(11.51±3.80) scores], meanwhile, the spiritual change [(5.07±2.67) scores] had no significant growth. The sum of PTGI was related positively to the role function of the patients. New possibilities (r=0.193), personal strength (r=0.290) and appreciation of life (r=0.284) were correlated positively with global health status. Multiple regression analysis indicated that personal strength (β=0.373, t=3.66) and appreciation of life (β=0.322, t=2.99) could predict positively to global health status, however, relating to others predicted negatively to global health status (β=-0.396, t=-3.63). Conclusion Posttraumatic growth has been found in cancer patients, including some predicting factors of patients' quality of life, such as personal strength, life appreciation and relating to others.

Objective To investigate the effect of suppressor of cytokine signaling-1 (SOCS-1)on expression of monocyte chemoattractant protein-1 (MCP-1)in human glomerular mesangial cells (HMCs) under high concentration of glucose. Methods Stable transfections of HMC with pCR3.1 vector and pCR3. 1-SOCS-1 were performed with hpofectamine 2000, and cells were selected with geneticin. Cells were stimulated with low glucose (LG, 5.5 mmol/L), high glucose (HG, 30 mmol/L), LG plus mannitol (24.5 mmol/L) and AG490 (10 μmol/L). The protein expression levels of SOCS-1, signal transducer and activators of transcription 1,3 (STAT1, STAT3),p-STAT1 and p-STAT3 were observed by Western blotting. The protein synthesis of MCP-1, FN and type Ⅳ collagen in the supernatants of the HMCs were detected by ELISA and radioimmunoassay. The expression level of SOCS-1 and MCP-1 mRNA was measured by BT-PCR.Results HG induced the expression of SOCS-1 protein and mRNA in HMCs in time-dependant manner, peaked at 4 h, and gradually decreased to baseline at 24 h. Compared with low glucose control group, the phosphorylation levels of STAT1 and STAT3 and the expression of MCP-1 mRNA [(0.39±0.05) vs (0.16±0.02)]were significantly increased in HMCs under high glucose medium (P <0.01 ). Exposure of HMCs to high glucose conditions showed high concentration of MCP-1 [(459±67) ng/L vs (241±19) ng/L], fibronectin [(5.84±0.61) mg/L vs (3.41±0.31) mg/L]and type Ⅳ collagen [(16.45±2.30) μg/L vs (9.56±1.52) μg/L]in the supernatants (all P<0.01).Overexpression of SOCS-1 inhibited the phosphorylation levels of STAT1 and STAT3 and the expression of MCP-1 mRNA [(0.34±0.04) vs (0.42±0.05)]in HMCs under high glucose condition (all P<0.05). Compared with vector control group, the concentration of MCP-1 [(387±47) ng/L vs (463±56) ng/L], fibronectin [(4.61±0.57) mg/L vs (5.76±0.74) mg/L]and type Ⅳ collagen [(13.4±2.32) μg/L vs (17.1±2.57) μg/L]was decreased in supernatants of HMCs with SOCS-1 overexpression (all P<0.05). Compared with HG group, the expression of MCP-1 mRNA (0.31±0.04) and the concentration of MCP-1 [(361±53) ng/L], FN [(5.46±0.71) mg/L]and type Ⅳ collagen [(15.2±1.97) μg/L]in supernatants were decreased in HMCs treated with AG490.Conclusion Overexpression of SOCS-1 inhibits overproduction of MCP-1 and ECM proteins in HMCs under high glucose conditions, which may be partly by regulating the phosphoryhtion of STAT1 and STAT3.

BACKGROUND:Salvia miltiorrhiza bone-setting capsule is a traditional Chinese medicine for the treatment of fractures due to activating blood circulation to dissipate blood stasis, reducing sweling and pain. OBJECTIVE: To observe the effects of Salvia miltiorrhiza bone-setting capsule on the fracture healing in a rat model of closed femoral fractures. METHODS: Rats were randomly divided into salvia miltiorrhiza bone-setting capsule group, physiological saline group and normal group. In the salvia miltiorrhiza bone-setting capsule group and physiological saline group, rat models of closed femoral fractures were prepared, and then given physiological saline and salvia miltiorrhiza bone-setting capsule 2 pils by intragastric administration. In the normal group, rats were housed normaly. At 7, 14 and 28 days after fractures, hematoxylin-eosin staining conditions, serum osteocalcin, the expression of colagen type I, and the expression of protein and mRNA calus transforming growth factor-beta 1 were observed in the salvia miltiorrhiza bone-setting capsule group and physiological saline group. RESULTS AND CONCLUSION: (1) Hematoxylin-eosin staining demonstrated that at 7 days after fractures, no significant difference was found in pathological changes of femoral fracture in salvia miltiorrhiza bone-setting capsule group and physiological saline group. At 14 and 28 days after fractures, pathological repair was more obvious in the salvia miltiorrhiza bone-setting capsule group than in the physiological saline group. (2) At 3 and 7 days after fractures, serum osteocalcin and the expression of type I colagen were significantly increased in the salvia miltiorrhiza bone-setting capsule group and physiological saline group (P < 0.05), and the expression trend was consistent in both groups. The expression was always higher in the salvia miltiorrhiza bone-setting capsule group than in the physiological saline group, and significant differences were found at 14 and 28 days after fractures (P < 0.01). (3) Transforming growth factor beta 1 expression reached a peak at 3 days after fractures, gradualy reduced, increased at 14 days (the second peak), and diminished at 28 days in the salvia miltiorrhiza bone-setting capsule group and physiological saline group. The expression trend of transforming growth factor beta 1 was consistent in the salvia miltiorrhiza bone-setting capsule group and physiological saline group. At 7, 14 and 28 days, the transforming growth factor beta 1 expression was higher in the salvia miltiorrhiza bone-setting capsule group than in the physiological saline group. (4) Results showed that salvia miltiorrhiza bone-setting capsule could promote fracture healing, and its mechanism was probably associated with serum osteocalcin, the expression of colagen type I and transforming growth factor-β1.

Aim To investigate the effects of fluvastatin on epithelial-myofibroblast transdifferentiation and activation of ERK1/2 in HKC cells stimulated by AGEs. Methods HKC are divided into four groups: control group, AGEs group, AGEs plus fluvastatin group and AGEs plus ERK1/2 MAP kinase inhibitor PD98059 group. Immunocytochemistry staining was used to detect expression of ?-SMA. The protein expressions of ?-SMA, E-cadherin, Col I, ERK1/2 and p-ERK1/2 were observed by Western blot. The protein synthesis of TGF-?1 in the supernatants of the HKC was detected by enzyme-linked immunoadsorbent assay (ELISA).?-SMA and E-cadherin mRNA were measured by reverse transcription and polymerase chain reaction (RT-PCR). Results Compared with those of control group,the expressions of ?-SMA protein and mRNA,and Col I were significantly increased in HKC cells with AGEs stimulation and there was high concentration of TGF-?1 in the supernatants. However, the expressions of E-cadherin protein and mRNA were decreased with AGEs stimulation. AGEs induced ERK1/2 phosphorylation in HKC in a time-dependent manner, being significant at 15 minutes and peak occured at 1 h. PD98059 and fluvastatin inhibited AGEs-induced activation of ERK1/2 and high expression of Col I and ?-SMA protein and mRNA, and reversed the expression of E-cadherin protein and mRNA induced by AGEs. Meanwhile, fluvastatin and PD98059 reduced the concentration of TGF-?1 in the supernatants of HKC with AGEs stimulation. Conclusions Fluvastatin inhibited AGEs-induced HKC epithelial-myofibroblast transdifferentiation and collagen I synthesis might be partly through blocking activation of ERK1/2.

OBJECTIVE:To optimize the placement of extra-machine medicines in the automated pharmacy and establish a ra-pid dispensing area to shorten medicine dispensing time. METHODS:12 588 prescriptions made within one week were collected from the outpatient pharmacy of our hospital,in which 29 kinds of extra-machine medicines used frequently were clustered on the basis of Pearson correlation coefficients. The extra-machine medicines used at a higher frequency were arranged in the storage posi-tions near to the medicine dispensing window,and those related to the above-mentioned medicines were stored in the positions adja-cent to them,thereby a rapid dispensing area was established. The effect of the above-said method was evaluated by comparing the time it took for the pharmacist to dispense medicines one week before and after the establishment of the rapid dispensing area. RE-SULTS:29 kinds of extra-machine medicines were clustered into 4 major categories,and stored in 4 positions in the rapid med-icine dispensing area respectively,and then the position codes were assigned. After the rapid dispensing area was established,the average single prescription dispensing time for the pharmacist decreased by about 9 s (40.43 s vs. 31.43 s,P<0.01). CONCLU-SIONS:The establishment of the rapid dispensing area based on cluster analysis method has increased the efficiency of dispensing medicines in the outpatient pharmacy of our hospital.
