Objective:To explore the correlation between lipid metabolism and coronary atherosclerosis in advanced aged patients with coronary heart disease (CHD) .Methods:A total of 95 advanced aged patients ,who were suspec-ted CHD and received coronary angiography (CAG) in our hospital from Dec 2010 to Dec 2013 ,were selected .Ac-cording to CAG results ,the 95 patients were divided into CHD group (n=43) and non-CHD group (n=52) .Their clinical data were retrospectively analyzed ,and the correlations between blood lipids and coronary atherosclerosis were analyzed .Results:Compared with non-CHD group , the ratio of low density lipoprotein cholesterol to high density lipoprotein cholesterol (LDL-C/HDL-C) [ (2.01 ± 0.65) vs .(2.38 ± 0.92) , P=0.024] significantly rose in CHD group .In CHD group ,number of diseased coronary vessel was positively correlated with triglyceride (TG) level ,LDL-C/HDL-C ,TG/HDL-C and atherogenic index of plasma (AIP) , r=0.183~0.256 (P<0.05 all) ,and inversely correlated with HDL-C level (r= -0.243 ,P<0.05);coronary stenosis degree was positively correlated with LDL-C/HDL-C ,TG/HDL-C and AIP (r=0.225~0.331 ,P<0.05) ,and inversely correlated with HDL-C level (r= -0.261 ,P<0.05) .In CHD group ,total Gensini score was positively correlated with blood lipid indexes (r=0.068~0.201 ,P<0.05 or <0.01) and inversely correlated with HDL-C level (r= -0.138 ,P<0.01) .Con-clusion:Elevated plasma HDL-C level can delay progression of coronary heart disease in advanced aged patients with coronary heart disease .LDL-C/HDL-C and AIP are indexes evaluating severity and risk of coronary atherosclerosis in patients with coronary heart disease .

AIM: To investigate the effects of tripchlorolide (TP) on proliferation and autophagy of human lung cancer A549 cells, and explore its mechanism.METHODS: MTT assay was performed to analyze the effect of TP on the viability of human lung cancer A549 cells.The A549 cells were treated with TP, and their autophagy was observed un-der the fluorescence microscope through acridine orange staining.Green fluorescence spots were observed by fluorescence microscopy through GFP-LC3 plasmid transfection experiment.The levels of LC3 and p-ERK in the A549 cells after TP treatment were determined by Western blot.RESULTS: The viability of human lung cancer A549 cells was significantly inhibited by TP in a dose-time dependent manner (P <0.05).The number of the intracellular acidic follicles dyed with bright red fluorescence was significantly increased after TP treatment in A549 cells.The number of green dot-like con-gregate autophagosomes in cell cytoplasm was significantly increased after TP treatment in the A549 cells transfected with GFP-LC3 plasmid, while the normal treatment only induced a few cells with autophagosome formation.At the same time, we did not observe the dot-like congregate autophagosomes after TP treatment in the A549 cells transfected with GFP-control plasmid.Compared with control group, the expression of LC3-II protein was up-regulated in A549 cells after TP treatment (P <0.01).Furthermore, treatment with TP in A549 cells for 48 h also led to a significant upregulation of phosphorylated form of ERK (P <0.01).In contrast, no significant change in the levels of total ERK protein was observed.Compared with 100 nmol/L TP group, TP +3-MA group down-regulated the protein levels of LC3-II (P <0.01) and p-ERK (P <0.01) in the A549 cells.CONCLUSION: TP significantly inhibits the growth of A549 lung cancer cells and induces the
autophagy, which may be correlated with upregulation of p-ERK protein.

AIM: To investigate clinical efficacy of two drug therapies ( acyclovir with prednisone acetate tablets, ganciclovir with prednisone acetate tablets and aspirin) for acute retinal necrosis syndrome.
METHODS: Thirty patients (40 eyes) with acute retinal necrosis syndrome in our hospital were randomly divided into group A and B. Group A was treated with acyclovir with prednisone acetate tablets, and group B was given ganciclovir with prednisone acetate tablets and aspirin. Clinical effects in the two groups were observed and compared.
RESULTS: After treatment, the overall response rate in group B (90%) was obviously higher than that in group A (70%), both of two regimens were effective, without significant difference (P>0. 05). There was no significant difference on the pre - treatment visual acuity between the two groups (P>0. 05). After different treatments, the visual acuity in group B was ≥0. 5 in 12 eyes, 0. 1≤and<0. 5 in 4 eyes, 0. 02 ≤ and < 0. 1 in 3 eyes, and no photosensitive in 1 eye. The visual acuity in group A was≥0. 5 in 9 eyes, 0. 1≤and<0. 5 in 3 eyes, 0. 02≤and<0. 1 in 6 eyes, and no photosensitive in 2 eyes. The recovery of visual acuity in group B was obviously better than that in A group ( P < 0. 05). The incidence of complications such as retinal tear, herpes, mouth ulcers, chickenpox, viral encephalitis and central nervous system diseases in group B (10%) was significantly lower than that in A group (35%,P<0. 05).
CONCLUSION: Two drug therapies ( acyclovir with prednisone acetate tablets, ganciclovir with prednisone acetate tablets and aspirin ) both have positive therapeutic effect, but the latter can better restore visual acuity and decrease the complications.

Dahuangzhechongwan has the renal protection on rat with adriamycin-induced nephrosclerosis, the mechanism may be relate with adjusting the balance of TXB_2 and 6-keto-PGF_(1?).

Objective To study the feasibility and safety of hand-assisted laparoscopic hepatectomy combined with splenectomy. Methods Hand-assisted laparoscopic hepatectomy combined with splenectomy was performed in 3 patients. A midline epigastric or right subcostal incision was made for hand-assisted port. The attachments of the spleen were dissected with a harmonic scalpel and the pedicle of the spleen was severed with the Endo-GIA. The transection of the liver was conducted using the harmonic scalpel dissection and nonabsorbable polymer clipping. The cut surface of the liver was closed by interrupted sutures. Results The operation was successfully completed in all the 3 patients. The surgical time was 130 min, 115 min, and 145 min, and the blood loss was 350 ml, 50 ml, and 150 ml, respectively. No serious postoperative complications occurred. The postoperative hospital stay was 9, 7, and 11 days, respectively. Follow-up observations for 6, 23, and 5 months showed no recurrence. Conclusions Hand-assisted laparoscopic hepatectomy combined with splenectomy is feasible and safe in selected patients .

Objective:To study the effect of sulforaphane(SFN) on the growth of human bladder cancer cell and its mechanism in vitro. Method:Morphological characteristics of T24 cell nucleus induced by SFN were observed by AO/EB fluorescein staining .The effect of SFN on the T24 cell cycle was determined by flow cytometry. The expression of TrxR at the transcriptional and translational levels were measured by RT-PCR and Western blot methods respectively. Results:(1) After the cells were treated with 10 ?mol/L and 20 ?mol/L SFN for 24 h and 48 h, nuclear fragmentation and apoptotic body were seen under fluorescence microscope. (2) SFN could block the cell cycle at the G0/G1 phase showed by flow cytometry. Moreover, the treatment of 20 ?mol/L SFN for 48h could cause the appearance of sub-G1 before G0/G1 phase. (3) The expression of TrxR mRNA were increased by the treatment of 10 ?mol/L SFN for 4 h, 10 h,24 h ,compared with the control group. Furthermore ,the treatment with high dose SFN (20 ?mol/L ) for 10h or 24 h could induce the expression of TrxR mRNA more significantly . (4)The expression of TrxR protein in the 10 ?mol/L SFN for 24 h group was augmented compared with the control group , and aftertreatment with 20 ?mol/L SFN for 8 h and 24 h, its expression was significantly higher than that in the control group . Conclusion:SFN can inhibit the growth of T24 cell ,induce apoptosis and arrest T24 cell in G0/G1 phase. Its mechanism is associated with the induction of TrxR both at the transcriptional and translational levels.
