Background and purpose:Previous studies have suggested Na+-Ca2+ exchanger isoform 1 (NCX1) as a key component of calcium homeostasis was involved in the tumorigenesis. However, the role of NCX1 and calcium signal in tumorigenesis of hepatocellular carcinoma (HCC) has not been explored. This study aimed to investigate the effect of NCX1 on cell proliferation and migration of HCC HepG2 cells in vitro and the possible mechanism.Methods:Both the real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot were applied to assess the expression of NCX1 mRNA and protein in normal hepatic cells (LO2), HCC cell line (HepG2), human normal hepatic tissues and hepatocellular carcinoma tissues. The change of intracellular calcium signal in LO2 and HepG2 cells via acti-vated NCX1 channel in the presence or absence of Na+ was examined by a confocal laser scanning microscope. The effects of NCX1 special inhibitor KB-R7943 on cell proliferation and migration of HepG2 cells were measured by MTT and cellscratch test.Results:Both mRNA and protein expression of NCX1 were higher in HCC tissues and cell line HepG2 than in the normal tissues and cell line LO2 (P<0.05). The activation of NCX1 channel induced a slight rise in cytoplasmic Ca2+concentration ([Ca2+]cyt) in normal cells, but caused a marked increase in cancer cells. And the NCX1 activation induced intracellular calcium increase was significantly reversed by NCX1 inhibitor KB-R7943 (P<0.05). Both NCX1-mediated proliferation and migration of HepG2 were also significantly attenuated by the KB-R7943 (P<0.05).Conclusion:NCX1 is up-regulated in HCC cells and tissues. The activation of NCX1 mediates intracellular calcium homeostasis. The inhibition of NCX1 activity can suppress the proliferation and migration of HepG2 cells. It is suggested that NCX1 may be involved in the development and progression of HCC.

Objective To explore the neuroprotective mechanism of propofol by comparing the influence of propofol and isoflurane on inflammatory cytokines ( TNF-α、IL-1、ICAM-1 ) in patients with intracranial tumors. Methods One hundred and sixty-eight patients with intracranial neoplasm were randomly divided into two groups:the propofol ( Group P) and isoflurane (Group I),84 cases in each. Patients were given with propofol (3-6 μg·mL-1) by plasma target-controlled infusion or with continuously inhaled isoflurane ( 1%-2%) , respectively. The serum levels of TNF-α, IL-1 and ICAM-1 were detected before anesthesia and at 0,24,and 48 h after operation. Results The serum levels of TNF-α,IL-1 and ICAM-1 were significantly increased after operation as compared to baseline in both groups. The serum level of TNF-α was(69. 11±8. 95) and (76. 26±11.28) μg·mL-1,IL-1 was(21.57±3.19) and (29.58±4.38) ng·L-1,and ICAM-1 was (1.63±0.24)and (1.94±0.29) g·L-1 at 24 h post operation in Group P and Group I,respectively. These inflammatory cytokine levels were significantly higher in group I compared to group P at 24 and 48 h after operation (P<0. 05 or P<0. 01). Conclusion The target-controlled infusion of propofol brings about lower level of inflammatory reaction than isoflurane inhalation in patients with intracranial neoplasm,which may attribute to the mechanism of brain protection against injury.

Objective:To investigate the role of TRPV5 and TRPV6 in intracellular calcium regulation and biological behaviors of SW480 colon cancer cells. Methods:qRT-PCR, Western blot, and immunocytochemistry were applied to determine the mRNA and protein ex-pression levels of TRPV5 and TRPV6 in SW480 colon cancer cell line upon treatment with TRPV5 and TRPV6 agonist, 1-25(OH)2D3, and inhibitor, CuCl2. The change of intracellular Ca2+level was examined with a confocal laser scanning microscope. Scratch test, MTT, and TUNEL assays were used to analyze the cell migration, proliferation, and apoptosis, respectively. Results:As an agonist of TRPV5 and TRPV6, 1-25(OH)2D3 significantly up-regulated the mRNA and protein expression levels of TRPV5 and TRPV6 in SW480 cell lines. On the other hand, CuCl2, being an inhibitor of TRPV5 and TRPV6, effectively down-regulated the TRPV5 and TRPV6 mRNA and protein expres-sion levels (P<0.05). The intracellular calcium concentration in SW480 cell line significantly increased upon treatment with 1-25 (OH)2D3, and significantly decreased with CuCl2 treatment (P<0.05). 1-25(OH)2D3 promoted cell proliferation and migration, and inhibit-ed apoptosis of SW480 cell in a time-and dose-dependent manner (P<0.05). However, CuCl2 significantly repressed cell proliferation and migration and induced apoptosis (P<0.05). Conclusion: TRPV5 and TRPV6 can affect the biological behaviors of colon cancer SW480 cells by regulating intracellular Ca2+level.

Objective To survey the prevalence of tendency on tendency of personality disorder among college students.Methods By means of stratified cluster sampling,498 students from 6 colleges in Shijiazhuang city and 204 students from 3 colleges in Beijing were studied through 'personality diagnostic questionnaire- revised UPDI'.Results The incidence rates on dependent personality (2.81%),histrionic personality (2.41% ) and borderline personality (2.21% ) were higher than obsessive- compulsive personality (0.40%) and schizoid personality (0.60%).The prevalence of personality disorder tendency was related to sex,major and years in college,blood type as well as their origins(from urban or rural).The overall incidence of personality disorder was 28.31% while the incidence rates of personality deviation and serious personality disorder tendency were 17.07% and 11.24% respectively.The incidence in males was higher than that in females.There appeared differences in dissociative personality,avoidant personality,paranoid personality,obsessive-compulsive personality,histrionic personality and narcissistic personality on people with different blood types.The scores of the city students were higher than that of the students from the rural areas regarding paranoid personality,dependent personality and narcissistic personality.Differences were also noticed between freshmen and students from other levels in the incidence rates on the tendency of avoidant personality disorder.Conclusion There were different incidence rates on the tendency of personality disorder among college students that related to sex,level in college and the origins where they were from(urban or rural).

OBJECTIVETo investigate the Churg-Strauss syndrome (CSS) associated lung involvement, concentrating on clinical characteristics, pathological findings of lung involvements, response to treatment, and prognosis.

METHODSWe retrospectively analyzed the characters of the clinical manifestations, thin-section CT and pathological findings of CSS. The study involved 16 patients. Clinical data were obtained by chart review. All patients underwent transbronchial lung biopsy (TBLB). Six of them underwent surgical lung biopsy as well.

RESULTSThe patients included 7 men and 9 women, aged from 14 to 61 years (median, 47.5 years). Extrathoracic organs involved included nervous system (7/16) and skin (5/16). Respiratory symptoms included cough (12/16), exertional dyspnea (11/16), hemoptysis (4/16), and chest pain (3/16). CT findings included bilateral ground-glass opacities (12/16), bilateral patchy opacities (12/16), and centrilobular nodules (6/16). The pathological findings of TBLB demonstrated increased eosinophils (3/16), vasculitis (3/16), and interstitial pneumonia (16/16). The pathological findings of surgical lung biopsy of 6 cases showed necrotizing vasculitis in 4 cases, capillaries in 5, eosinophilic pneumonia in 3, granulomas in 2, and airway abnormalities in 3. All patients improved in symptoms after therapy during the study period (range, 3 to 51 months; median, 15 months).

CONCLUSIONSAsthma may be present in CSS patient when there is bronchial involvement. Ground-glass opacities and consolidation seen on high-resolution CT reflect the presence of eosinophilic pneumonia, vasculitis, and pulmonary alveolar hemorrhage. TBLB has significant limitations for the diagnosis of CSS. Early diagnosis and therapy can result in satisfactory prognosis.

OBJECTIVETo study the effect of Fuzheng Sanjie recipe in regulating tumor-associated macrophages (TAMs) in Lewis lung cancer mice.

METHODEfforts were made to establish the Lewis lung cancer mouse model, weigh tumors and calculate the anti-tumor rate. The immunohistochemical method was used to examine the infiltration degree of CD68 + in tumor tissues in each group. ELISA was used to examine the content of IFN-γ, TGF-β, IL-4, IL-13, IL-6, IL-10, IL-12, TNF-α in mice serum.

RESULTCompared with the tumor-bearing model group, all of the other groups showed higher tumor inhibition rates, i. e. 50.28% for the DDP group, 34.37% for the TCM-preventing group and 66.76% for the Chinese and western medicine group, with statistical difference (P < 0.05), but without statistical difference in the infiltration degree of CD68+. The expressions of the IFN-γ, IL-6, IL-12 in tumor-bearing groups were lower than that in the blank control group, but with higher contents of IL-4, IL-13, TGF-β. Intervened with different drugs, there were significant differences in content among some relevant cytokines (P < 0.05), as well as statistical differences among the TCM prevention group, the Chinese and western medicine group and the tumor-bearing control group (P <0. 05) , but without statistical difference in TNF-α and IL-10 content from the tumor-bearing control group (P < 0.05).

CONCLUSIONFuzheng Sanjie recipe could reverse the immune remodeling effect and control the tumor growth by down-regulating the expressions of IL-4, IL-13, TGF-α in lung cancer immune microenvironment and up-regulating the expression of IFN-γ.
