Objective To study the clinic manifest-rations, mechanism, diagnosis and treatment of pulmonary arterial hypertention (PAH) in systemic lupus erythamatosus (SLE). Methods The clinic symptoms, laboratory tests. Doppler tests of patients who were diagnosed with PAH and SLE during last five years were analyze retrospectively. Results Anti-RNP antibody's prevalence rate was high. The presence of pulmonary arterial perssure (PAP) was not related to SLE disease active index (SLEDAI). Those who had PAP higher than 45 mm Hg were prone to have Raynaud's phenomenon PAH had no association to auto-antibodies and other systemic lesions. There were no differences in clinic features, auto-antibodies and other examinations between those with kidney injure and without kidney injure. Conclusion PAH may develop insidiously in SLE, so early diagnosis and prompt treatment of PAH can improve the prognosis.

AIM: Valproic acid (VPA) is a histone deacetylase inhibitor and is believed to have anti-tumor activity. The present study aims to investigate the effect of VPA on the, apoptosis and cytokine synthesis of human peripheral lymphocytes. METHODS: The activation and cytokine synthesis in lymphocytes in whole blood stimulated with phorbol dibutyrate (PDB) and ionomycin were evaluated with flow cytometry after fluorescent staining. The mitochondrial membrane potential was examined using 3, 3-dihexyloxacarbocyanine iodide [DiOC6(3)]staining. RESULTS: VPA at low doses (1 and 5 mmol/L) promoted CD69 expression in activated lymphocytes, whereas it turned to inhibit the expression of CD69 at a high dose (25 mmol/L). Meanwhile, VPA at low doses increased the mitochondrial membrane potential, while a high dose of VPA decreased it in activated lymphocytes. Furthermore, interleukin-2 (IL-2) synthesis was enhanced by low doses of VPA but inhibited by a high dose. However, interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) synthesis were dose-dependently enhanced by VPA as compared with those of PDB plus ionomycin-treated cells. CONCLUSION: VPA exerts biphasic effect on the further activation and apoptosis of human peripheral lymphocytes stimulated with mitogens and exhibits differential activity on the synthesis of several important cytokines in human lymphocytes.

Objective To explore the use of CA199,CEA,CA50 and ALP combined with magnetic resonance imaging (MRI) in diagnosis of intrahepatic bile duct stones with early bile duct carcinoma.Methods The clinical diagnosis of 36 cases of patients with hepatolithasis-associated intrahepatic cholangiocarcinoma (HICC) and 118 cases with intrahepatic duct stone (IHDS) were analyzed retrospectively.Serum CA199,CEA,CA50,ALP and magnetic resonance (MRI,MRCP) were performed and the results were analyzed.Results Abdominal pain discomfort in Hepatolithasis-associated intrahepatic cholangiocarcinoma showed multiple symptoms.Three typical Charcot syndromes were rare.On the gender distribution,intrahepatic bile duct stones was frequently found in women,on the contrary,Hepatolithasis-associated intrahepatic cholangiocarcinoma was frequently more found in men (P ＜0.05) Abdominal pain and fever in patients of Hepatolithasis-associated intrahepatic cholangiocarcinoma was more than that of patients with Intrahepatic bile duct stone (P＜0.05) When alkaline phosphatase (ALP) was more than 169 U/L,significant difference was seen between two groups (P＜ 0.05) According to the diagnosis of HICC,the accuracy of CA199,CEA,CA50 combined with ALP was 88.6％,the accuracy of magnetic resonance examination alone was 90.2％,and the accuracy of multiple serological markers and magnetic resonance was 95.5％.Conclusion MRI combined with serum CA199,CEA,CA50 and ALP can effectively improve the HICC preoperative diagnosis rate.

Aim To study the mechanism of cucurb-itacin E ( CuE )-induced autophagy in HeLa cells. Methods Improved MTT assay was adopted to meas-ure the effect of CuE on cell proliferation. Western blot was used to determine the phosphorylation levels of downstream signaling proteins of mTORC1 and the ex-pression of autophagy associated proteins. ResultsCuE inhibited the proliferation of HeLa cells in a dose-dependent manner, and the 24-h IC50 of CuE was 4. 01μmol· L-1 . CuE significantly inhibited the phospho-rylation of p70 S6 K in a time-and dose-dependent man-ner as evidenced by decreased phosphorylation levels of
the mTORC1 substrate. Meanwhile, the expression of LC3-II, a marker for autophagosome formation, was elevated by CuE treatment, and was further increased in the presence of chloroquine. Furthermore, CuE re-duced the levels of p62/SQSTM1 . These results indi-cated that CuE induced autophagy in HeLa cells. The decreased levels of phosphorylated ULK1 S757 were posi-tively correlated with autophagy induction in HeLa cells. Conclusion CuE is likely to induce autophagy through inhibiting mTORC1 activity.
