Familial isolated pituitary adenoma (FIPA) is an autosomal dominant disease, characterized by low penetrance, early-onset disease, more invasive tumor growth, as well as somatotroph and lactotroph adenomas in most cases. It has been indicated that the aryl hydrocarbon receptor interacting protein (AIP) gene is a tumor suppressor gene. Many heterozygous mutations have been discovered in AIP in about 20% of FIPA families. However, the exact molecular mechanism by which its disfunction promotes tumorigenesis of pituitary is unclear.

Clinically nonfunctioning pituitary adenomas are the most common types among pituitary adenomas. These tumors are usually diagnosed in their later stages due to the absence of clinical symptoms and detectable hormonal hypersecretion. Although these tumors are benign, they are hard to be completely removed during neurosurgery due to the massive invasion into the surrounding tissues at diagnosis. Furthermore, relapse is common. In recent years, medical treatment of pituitary adenomas has witnessed a rapid development. New medications have shown certain effectiveness in reducing the tumor size and improving the clinical symptoms.

OBJECTIVETo investigate the effect of Qingre Quyu Granule (清热祛瘀颗粒, QRQYG) on stabilizing vulnerable plaques in apolipoprotein E (ApoE) deficient mice.
METHODSSeventy-two male ApoE deficient mice were given a high-fat diet from 6 weeks of age. At the 16th week, all the mice were randomized into 3 groups: the QRQYG group, the simvastatin group, and the control group. Sixteen weeks after administration of 0.9 g/kg QRQYG, 3 mg/kg simvastatin or 10 mg/kg sodium chloride per day to the respective groups, the animals were euthanized. The pathological morphologic changes in the vulnerable plaques were evaluated, the matrix metalloprotease-9 (MMP-9) expression was measured by immunohistofluorescence, the soluble intercellular adhesion molecule 1 (ICAM-1) was determined by ELISA, the nuclear factor kappaB (NF-κB) subunit p65 was measured by quantitative RT-PCR, and, finally, thrombospondin-1 (TSP-1) was determined by the immunohistochemical method.
RESULTSThe plaque cross-sectional area in the brachiocephalic artery (23.7%, P<0.01), the lipid core of the plaque (43.1%±3.1%), and the number of buried fibrotic caps of the plaque were significantly decreased in the QRQYG group compared to the control group (both P<0.01); furthermore, the thickness of the fibrotic cap of the plaque increased and the intra-plaque hemorrhage of the plaque decreased. The serum soluble ICAM-1 (27.1±5.1 μg/mL), the protein expression of MMP-9 and TSP-1 and the p65 mRNA expression increased in the QRQYG group in comparison with the control group (P<0.05 or P<0.01).
CONCLUSIONQRQYG could stabilize the vulnerable plaque through inhibition of the inflammatory response.

This study was aimed to investigate the killing activity of cytokine-induced killer (CIK) cells after being incubated with autologous tumor cell lysate-pulsed dendritic cells (DC) and to evaluate the clinical efficacy and side effect of autologous tumor cell lysate-loaded DC in combination with CIK on relapsed or refractory non-Hodgkin's lymphoma (NHL). Peripheral blood mononuclear cells (PBMNC) were isolated from 9 patients with NHL, and cultured with granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) to produce DC. The DC were pulsed with autologous tumor cell lysate. T lymphocytes from PBMNC were cultured with interferon-gamma (IFN-gamma), IL-2, CD3-moAb, and IL-1alpha to prepare CIK. After receiving the immunotherapy of DC and CIK, immunologic and clinical responses were evaluated. The results showed that the AgNOR, CD3(+)CD8(+) and CD3(+)CD56(+) ratio were markedly improved after the immunotherapy (p < 0.01); IFN-gamma and IL-12 levels in supernatant of DC-CIK group were higher than that in CIK group (p < 0.01); Tumor size were significantly decreased after the immunotherapy (p < 0.05). Except transient fever and chill, no remarkable adverse event happened during or after the treatment. It is concluded that the autologous tumor cell lysate-pulsed DC in combination with CIK show ability to specifically kill the lymphoma cells, obviously increases the IS value of Ag-NOR in peripheral lymphocytes, secretes cytokines higher than CIK cells alone. This combination displays the short-term satisfied efficacy on NHL through inducing specific antitumor immunity, and can be used as an effective adjuvant measure for the routine therapy of NHL.

OBJECTIVETo investigate the expression of KIAA0101 protein in gastric carcinoma cells, and to explore the effects of its down-regulation on the cell proliferation, cell cycle and invasion.
METHODSWestern blot was used to detect KIAA0101 protein expression in three gastric carcinoma cell lines including MKN-28, SGC-7901 and MKN-45. KIAA0101 siRNA and control siRNA were utilized to transfect MKN-45 cells, respectively. CCK-8 was used to analyze the changes of cell proliferation, and flow cytometry to examine the changes of cell cycle distribution. Finally, Boyden chamber was used to detect the ability of cell invasion.
RESULTSRelative level of KIAA0101 protein in MKN-45 cells was significantly higher than those in MKN-28 and SGC-7901 cells, and there was significant difference among the three cell lines (P < 0.05). The result of CCK-8 study demonstrated that, compared with untreated group and control siRNA group, the proliferation of MKN-45 cells in KIAA0101 siRNA group was significantly inhibited (P < 0.05). Additionally, the result of cell cycle analysis revealed that the percentage of cell number in G(0)/G(1) phase in KIAA0101 siRNA group [(61.47 ± 0.89)%] was significantly higher than those in untreated group [(47.43 ± 0.85)%] and control siRNA group [(48.43 ± 0.73)%; F = 271.653, P = 0.000]. Further, Boyden chamber assay showed that the cell numbers migrated to Matrigel in KIAA0101 siRNA group (61.51 ± 4.76) were significantly lower than those in untreated group (138.74 ± 10.16) and control siRNA group (132.93 ± 11.25; F = 65.949, P = 0.000).
CONCLUSIONSDown-regulation of KIAA0101 expression leads to an inhibition of cell proliferation, cell cycle and cell invasion. It may provide a novel target for the treatment of patients with gastric carcinoma.

AIM:To investigate the effects of ubiquitin-specific peptidase 9, X-linked (USP9X) down-regula-tion on apoptosis and invasion ability in gastric carcinoma cells, and to explore its possible molecular mechanisms. METH-ODS:USP9X small interfering RNA (siRNA) and control siRNA were used to be transfected into gastric carcinoma AGS cells. The cells were divided into 3 groups, including untreated AGS group, control siRNA group and USP9X siRNA group. The expression of USP9X at mRNA and protein levels in the AGS cells with different treatments was determined by real-time PCR and Western blot. The cell viability was analyzed by CCK-8 assay. Flow cytometry and Boyden chamber were employed to examine the apoptosis and invasion ability of the AGS cells. RESULTS:USP9X siRNA significantly down-regulated the expression of USP9X at mRNA and protein levels in the AGS cells. Down-regulation of USP9X markedly induced apoptosis and reduced invasion ability of the gastric carcinoma AGS cells. Notably, down-regulation of USP9X sig-nificantly reduced the protein expression of Mcl-1 and MMP-2, but markedly increased the protein level of Bax. CON-CLUSION:USP9X may be a key regulator for apoptosis and invasion in gastric carcinoma.

OBJECTIVETo investigate the health care status of female workers exposed to occupational hazards in Haidian district of Beijing and improve the labor protection of female workers.
METHODSA questionnaire provided by National Center for Women and Children's Health of Chinese CDC was used in the survey conducted to collect information about health care status of female workers in 141 factories with occupational hazards including chemical poisons and physical factors (noise, libration, microwave, high frequency and low temperature).
RESULTS141 factories were investigated, including 53 state-owned enterprises, 21 collective enterprises, 46 joint-stock enterprises, and 21 non-public enterprises. 12 251 female workers were surveyed, 10.19% (1249/12 251) of whom were exposed to occupational hazards. Of 141 factories studied, 16.31% (23/141) had no labor protection management organization.27.66% (39/141) did not provide pre-employment physical examination service to female workers.48.94% (69/141) didn't establish labor protection system for female workers in menstrual period. While, 21.28% (30/141) of the studied institutes deducted some salaries in the pregnancy, and 32.62% (46/141) deducted their wages during the puerperal period. 2.13% (3/141) arranged female workers in the posts which are forbidden by law (continuous heavy work load operation).9.93% (14/141) arranged pregnant female workers on the post forbidden by law.31.91% (45/141) and 33.33% (47/141) would deduct the time of prenatal medical examination and lactation from their working hours, respectively.39.01% (55/141) didn't afford the cost of fertility. 68.09% (96/141) had annual gynecological examination.45 factories were collected occupational examination reports, accounted for 31.91% (45/141). No female workers were found suffering from occupational disease. Of the 1865 occupational hazard factor monitoring points in 34 factories, there were 155 monitoring points, which were all noise monitoring points, did not meet the standard.
CONCLUSIONThe current health-care status of female workers is not optimistic. It is necessary to consistently improve health care legislations, establish coordinated management mechanism and strengthen the publicity of policy to protect female workers.

OBJECTIVETo explore the effect of down-regulation of astrocyte elevated gene-1 (AEG-1) expression on cell proliferation and cell cycle of gastric carcinoma cells, and its possible molecular mechanism.
METHODSControl siRNA and AEG-1 siRNA were transfected into gastric carcinoma SGC-7901 cells. 48 h after transfection, the cells were divided into 3 groups including untransfected, siRNA control and AEG-1 siRNA transfection groups. Expressions of AEG-1 mRNA and protein in the 3 group cells were detected by real-time quantitative PCR and Western blot. The changes of cell proliferation were examined using CCK-8 kit, and the cell cycle distribution was detected by flow cytometry. Finally, expressions of cell proliferation and cell cycle related proteins were detected by Western blot.
RESULTSReal-time quantitative PCR and Western blot demonstrated that compared with the untransfected and siRNA control groups, expressions of AEG-1 mRNA and protein were significantly down-regulated in the AEG-1 siRNA transfection group (P < 0.05), but there was no significant difference between the untransfected and siRNA control groups (P > 0.05). Furthermore, in vivo experiment confirmed a significant down-regulation of AEG-1 protein in the AEG-1 siRNA transfection group (P < 0.05). In addition, AEG-1 siRNA obviously inhibited the proliferation of SGC-7901 cells at different time points after transfection with AEG-1 siRNA. The percentage of cells in G0/G1 phase in the AEG-1 siRNA transfection group [(61.26 ± 1.25)%] was significantly higher than those in the untransfected group [(46.17 ± 1.91)%] and siRNA control group [(46.46 ± 1.96)%], and there was a significant difference between them (all P < 0.001). Furthermore, the result of Western blotting revealed that down-regulation of AEG-1 expression evoked the down-regulation of cdk2 and cyclin D1 expressions and elevation of p21 expression in vitro and in vivo.
CONCLUSIONSThe inhibition of cell proliferation and cell cycle arrest mediated by down-regulation of AEG-1 expression may be closely associated with the changes of expression of cell cycle related proteins including cdk2, cyclin D1 and p21.
