Conclusion The Co-NQ possesses benefits of both naphthoquine and artemisinine, acting rapidly, with a short course of only one dose and a high cure rate. The regime is well tolerated by patients.

Background Plasma membrane calcium ATPase 3 (PMCA3) participates in the regulation of Ca2+ level in lens epithelial cells (LECs),which may be associated with the pathogenesis of cataract.It has been proved that ultraviolet B (UVB) is one of causing-factors of cataract.However,the effect of UVB on the expression of PMCA3 in LECs is unclear.Objective This study was to investigate the effects of UVB irradiation on the expression of PMCA3 in human LECs B-3.Methods HLE B-3 cells were cultured and passaged.The cells were exposed to 0,5,10 and 20 mJ · s/cm2 UVB for 0,20,40,80 s,respectively and further cultured for 24,48 and 72 hours.MTT assay was used to detect the cell proliferation rate.JC-1 staining was used to detect the changes of mitochondrial membrane potential (△ψm) in the cells.The intracellular reactive oxygen species (ROS) level was detected by DCFH-DA staining,and cell apoptosis was evaluated using annexin V-FITC/PI staining.In addition,the intracellular calcium ion (Ca2+) concentration in the cells was assayed with Fluo-3/AM staining.The expression levels of PMCA3 mRNA and PMCA protein in the HLE B-3 cells were detected by real-time PCR and Western blot,respectively.Results The survival rates of the cells were significantly reduced with the increase of irradiated intensity of UVB and the lapse of time (Fgroup =72.411,P =0.000 ; Ftime =36.588,P =0.000),and the survival rates of the cells in the 10 mJ · s/cm2 and 20 mJ · s/cm2 UVB for 24 hours were (75.3 ± 2.2) ％ and (48.7 ±4.5) ％,respectively,which were significantly lower than those in the 0 mJ · s/cm2 UVB group ([100.0±0.0] ％) (P=0.001,0.000).The survival rates of the cells in the 5,10,20 mJ · s/cm2 UVB for 48 hours were (84.9± 1.2) ％,(69.3±17.4)％ and (32.8±4.5)％,showing significant declines in comparison with the 0 mJ · s/cm2 UVB group ([100.0±0.0] ％) (P =0.047,0.000,0.000).In 72 hours following 5,10,20 mJ · s/cm2 UVB irradiation,the survival rates of the cells were (55.1 ± 3.0) ％,(42.1 ± 1.9) ％ and (26.1 ±4.7) ％,respectively,with significant differences in comparison with the 0 mJ · s/cm2 UVB group ([100.0 ± 0.0] ％) (P =0.000,0.000,0.000).JC-1staining exhibited the intracellular red fluorescence in the normal cells group.However,in the 5 mJ · s/cm2 UVB group,weak green fluorescence was seen,and the green fluorescence was enhanced in the 10 mJ · s/cm2 and 20 mJ · s/cm2 UVB groups.After irradiated by 5,10 and 20 mJ · s/cm2 UVB,the ROS levels in the cells increased from 0.4％ to 35.8％,51.9％ and 76.7％,respectively.The apoptosis and necrosis rate of the cells was 2.0％ in the 0 mJ · s/cm2 UVB and 4.2％,7.6％,15.1％ in the 5,10,20 mJ · s/cm2 UVB groups,respectively.The Ca2+ level raised by (1.2±0.1) and (1.3±0.1) folds in the 10 and 20 mJ · s/cm2 UVB groups more than that in the 0 mJ · s/cm2 group (P =0.039,0.004).The expression levels of PMCA3 mRNA in the cells were significantly reduced (P=0.001,0.004,0.000),and the expression levels of the PMCA protein were declined in the 5,10 and 20 mJ · s/cm2 UVB groups compared with the 0 mJ · s/cm2 UVB group (P=0.000,0.000,0.001).Conclusions UVB irradiation causes cataract probably through downregulating the expression of PMCA3 in human LECs and inducing apoptosis of LECs in a dose-and time-dependent manner.

Objective Non-alcoholic fatty liver ( NAFL) is a metabolic disease and levocarnitine can be used to improve the energy metabolism of the patient .This study aimed to evaluate the clinical efficacy of levocarnitine in the treatment of NAFL . Methods We retrospectively analyzed 85 cases of NAFL treated by lifestyle intervention (control group, n=40) or by lifestyle intervention +levo-carnitine medication (medication group, n=45).In addition to lifestyle intervention, the patients in the medication group received oral levocarnitine at 10 mL tid for 4 weeks followed by a reduced dose of 10 mL bid for another 8 weeks. Results Twelve weeks after treat-ment, 37 cases (82.2%) in the medication group showed remarkable improvement and the other 8 failed to respond.In the control group, 23 cases (57.5%) were improved and 17 cases remained unimproved .There were statistically significant differences in the rate of therapeutic effectiveness between the two groups of patients (P<0.01).No adverse effects were observed during the levocarnitine medi-cation. Conclusion Lifestyle intervention +levocarnitine medication can improve NAFL .

Objective The control rate of blood pressure in hypertension patients is very low in our country , while follow-up intervention can significantly improve the situation .This study aimed to evaluate the clinical effects of anti-hypertension under follow-up intervention . Methods From October 2013 to October 2014 , 125 patients with hypertension were chose as the study objectives after first clinical anti-hypertension and were divided into intervention group (follow-up,n=65) and control group(no follow-up,n=60). Comparative analysis was made in blood pressure control , compliance with therapy and cardiovascular event incidence between the two groups after 12 weeks'intervention. Results After 12 weeks, diastolic and systolic blood pressure in intervention group was signifi-cantly lower than that in control group (P<0.05).Significant difference was also found in the compliance with drug-taking between in-tervention group and control group (73.8%vs 43.3%, P<0.01).During the follow-up period, 1 case in the control group suffered stroke and unstable angina pectoris hospitalized for treatment . Conclusion Follow-up intervention after clinical service can improve the efficacy of blood pressure control and encourage the patients to live healthy lifestyle .

Objective:To discuss the influence of bifid triple viable enteric-coated capsules on liver function and inflammatory fac-tor in the patients with non-alcoholic steatohepatitis ( NASH) . Methods:Totally 70 cases of patients with NASH were selected and di-vided into the control group and the observation group at random. The patients in the two groups were all given routine hepatoprotective therapy. The patients in the observation group were additionally given 420mg bifid triple viable enteric-coated capsules, three times a day for 4 weeks. Except for bifid triple viable enteric-coated capsules, the patients in the control group were given the same medical treatment as that in the observation group. The changes of liver function index, serum high sensitivity C reaction protein ( hs-CRP) , IL-6 and IL-8 levels in the two groups before and after the medical treatment were observed and the security was compared. Results:After the 4-week medical treatment, ALT, GGT, serum hs-CRP, IL-6 and IL-8 levels in the two groups were obviously declined than those before the treatment (P<0. 05 or P<0. 01), and the declining rate in the observation group was much higher than that in the control group (P<0. 05). Totally 6 and 4 cases of adverse drug reaction (ADR) respectively appeared in the observation group and the control group during the medical treatment with mild symptom, and the difference was without statistical significance (P>0. 05). Conclusion:Bifid triple viable enteric-coated capsules in the treatment of NASH can obviously reduce the serum hs-CRP, IL-6 and IL-8 levels, inhibit the intrahepatic inflammation and immunologic injury, and improve the liver function index with high security.

Objective To investigate the suppressive effect of exogenous carbon monoxide (CO) on abnormal platelet exocytosis and its possible molecular mechanism. Methods Venous blood was collected from healthy volunteers. Platelet-rich plasma (PRP) was isolated from the blood by differential centrifugation. The PRP was randomly divided into five groups by random number table, namely normal control group, lipopolysaccharide (LPS) group (challenged with 10 mg/L LPS), inactively exogenous carbon monoxide releasing molecule 2 (iCORM-2) group (given 10 mg/L LPS + 50 μmol/L iCORM-2 for intervention), exogenous carbon monoxide releasing molecule 2 (CORM-2) 10 μmol/L and 50 μmol/L groups (given 10 mg/L LPS + CORM-2 10 μmol/L or 50 μmol/L for intervention). After 30 minutes, enzyme linked immunosorbent assay (ELISA) was used to determine the platelet-derived growth factor BB (PDGF-BB) and matrix metalloproteinase 2 (MMP-2). Chemical fluorescein method was used to determine the platelet adenosine triphosphate (ATP). Flow cytometer was used to determine the expression of P-selectin. The expressions of Toll-like receptor 4 (TLR4), phosphorylation of protein kinase Cθ (PKCθ) and syntaxin binding protein 1 (STXBP-1) were determined by Western Bolt. The soluble N-ethylmaleimide-sensitive factor-attachment protein receptors (SNAREs) complex formation [syntaxin 2-synaptosomal-associated protein 23-vesicle associated membrane protein 8 (STX2-SNAP23-VAMP8)] mediated by STXBP-1 was determined by immunoprecipitation. Results ① Compared with normal control group, the platelet release of PDGF-BB, MMP-2 and ATP was significantly increased after LPS challenge, and the P-selectin expression of platelet was also obviously up-regulated [PDGF-BB (μg/L): 127.53±1.78 vs. 94.35±5.84, MMP-2 (ng/L): 51.87±9.20 vs. 35.83±3.17, ATP (μmol/L): 1.288±0.056 vs. 0.975±0.010, P-selectin: (3.93±0.19)% vs. (0.44±0.10)%, all P < 0.05]. The increases in platelet release of PDGF-BB, MMP-2 and ATP were suppressed by 10 μmol/L or 50 μmol/L CORM-2 administration, as well as high-expression of P-selectin in a dose-dependent manner [PDGF-BB (μg/L): 114.68±1.35, 97.08±6.14 vs. 127.53±1.78, MMP-2 (ng/L): 32.67±8.00, 24.63±1.63 vs. 51.87±9.20, ATP (μmol/L): 0.999±0.015, 0.965±0.008 vs. 1.288±0.056, P-selectin: (1.95±0.27)%, (0.94±0.11)% vs. (3.93±0.19)%, all P < 0.05]. ② Compared with normal control group, LPS challenge resulted in a significant increase in the expression of TLR4 and the phosphorylation of PKCθ and STXBP-1 [TLR4 (gray value): 1.21±0.38 vs. 0.67±0.06, p-PKCθ (gray value): 1.36±0.20 vs. 0.44±0.03, p-STXBP-1 (gray value): 1.13±0.06 vs. 0.59±0.04, all P < 0.05]. The increases in above parameters were suppressed by 10 μmol/L or 50 μmol/L CORM-2 administration in a dose-dependent manner [TLR4 (gray value): 0.76±0.05, 0.65±0.04 vs. 1.21±0.38; p-PKCθ (gray value): 0.71±0.07, 0.47±0.10 vs. 1.36±0.20; p-STXBP-1 (gray value): 0.56±0.02, 0.48±0.01 vs. 1.13±0.06, all P < 0.05]. ③ Compared with normal control group, the SNAREs proteins in platelet that combined with STXBP-1, including STX2, SNAP23 and VAMP8, were obviously increased after LPS challenge [STX2 (gray value): 1.35±0.06 vs. 0.57±0.04, SNAP23 (gray value): 0.97±0.04 vs. 0.30±0.12, VAMP8 (gray value): 1.37±0.12 vs. 0.77±0.10, all P < 0.05]. The increases in SNAREs complex formation were suppressed by 10 μmol/L or 50 μmol/L CORM-2 administration in a dose-dependent manner [STX2 (gray value): 0.77±0.02, 0.39±0.03 vs. 1.35±0.06, SNAP23 (gray value): 0.41±0.03, 0.22±0.08 vs. 0.97±0.04, VAMP8 (gray value): 0.85±0.07, 0.66±0.07 vs. 1.37±0.12, all P < 0.05]. There was no significant difference in the above mentioned parameters between iCORM-2 group and LPS group. Conclusions LPS-induced abnormal secretion of platelet was suppressed by CORM-2 administration. The mechanism may involve the TLR4/PKCθ/STXBP-1 signaling pathway activation and the SNAREs complex formation.
