As a T cell subsets growth factor,interleukin-2 (IL-2) can inhibit cancer cell proliferation,reduce tumorigenicity and transitivity,improve local tumor microenvironment,enhance the immunogenicity of hepatocellular carcinoma cells,reduce the load of hepatitis virus and greatly enhance the ability of anti-tumor.On the other hand,it can enhance tumor hypercoagulable state.The effect of IL-2 on primary hepatic carcinoma and its potential clinical value have a bright future.

Objective:To observe the effect of CD40 siRNA on expression of IFN-γ,IL-17,IL-4 and anti-dsDNA antibody of systemic lupus erythematosus (SLE)animal model MRL/Lpr mice and to discuss its therapy on MRL/Lpr mice.Methods:In the study,16 female MRL/Lpr mice were randomly divided into control group (n =4),empty vector group (n =4),CD40-siRNA1 group (n =4)and CD40-siR-NA2 group (n =4).The vectors expressing siRNA against CD40 were injected by tail veil into MRL/Lpr mice,while MRL/Lpr mice in control group and empty vector group were injected with the same dose of PBS and pGFP-V-RS vector respectively.The injection was given six times and every one day.The mice were sacrificed 14 d after injection,and the spleen tissue was weighed.The pGFP-V-RS was labeled by green fluorescent protein(GFP)and the tissue sections were observed whether siRNA expressed in the spleen.The expression levels of IFN-γ,IL-17,IL-4 and anti-dsDNA antibody in the sera were detected by ELISA method on the 1st day before the first time and the 2nd,5th,8th,11th,and 14th days after last injection,and the expression levels of CD40 mRNA in spleen tissue of MRL/Lpr mice were detected by RT-PCR and the expression levels of CD40 protein in spleen tissue of MRL/Lpr mice were detected by immunohistochemistry method.Results:The expression vector of CD40-siRNA could express in the spleen of MRL/Lpr.The spleens in CD40-siRNA1 group [(78.85 ±5.61 )mg]and CD40-siRNA2 group [(80.25 ±4.07)mg]were lower than those in control [(141.88 ±7.81)mg]and empty vector group [(153.10 ±7.60)mg].The levels of IL-17,IFN-γand anti-dsDNA antibody were lower and the levels of IL-4 was higher in CD40-siRNA1 group and CD40-siRNA2 group on the 2nd,5th and 8th days after last injection than on the 1st day before the first time (P <0.05).The levels of IFN-γin CD40-siRNA1 group were (118.74 ±10.32)ng/L,(115.24 ±8.26)ng/L and (113.71 ±5.02)ng/L in turn,the levels of IFN-γin CD40-siRNA2 group were (117.83 ±6.83)ng/L,(114.07 ±0.97)ng/L and (112.67 ±9.66)ng/L in turn.The levels of IL-17 in CD40-siRNA1 group were (7.05 ±0.41 ) ng/L,(6.34 ±0.76)ng/L and (5.83 ±0.43)ng/L in turn,the levels of IL-17 in CD40-siRNA2 group were (7.07 ±0.22)ng/L,(6.35 ±0.49)ng/L and (6.12 ±0.80)ng/L in turn.The levels of anti-dsDNA antibody in CD40-siRNA1 group were (7.51 ±0.29 )ng/L,(6.74 ±0.45 )ng/L and (6.32 ±0.39)ng/L in turn,the levels of anti-dsDNA antibody in CD40-siRNA2 group were (8.19 ± 0.38)ng/L,(7.14 ±0.50)ng/L and (6.48 ±0.29)ng/L in turn.The levels of IL-4 in CD40-siRNA1 group were (26.51 ±1.81)ng/L (27.80 ±1.72)ng/L and (28.08 ±2.21)ng/L in turn,the level of IL-4 in CD40-siRNA2 group were (26.28 ±2.03)ng/L,(28.15 ±2.95)ng/L and (28.37 ± 1.71)ng/L in turn.The expression levels of IL-17 and IFN-γantibody increased gradually and the levels of IL-4 decreased gradually in CD40-siRNA1 group and CD40-siRNA2 group on the 11th and 14th days after last injection,then reached to the levels of control group and empty vector group (P >0.05). Though the levels of anti-dsDNA antibody in CD40-siRNA1 group and CD40-siRNA2 group on the 11th day was higher than on the 8th day,there was more significance than those in control group and empty vector group (P <0.05).There was no significance between the 4 groups on the 14th day.The levels of CD40 mRNA and protein were lower in CD40-siRNA1 group and CD40-siRNA2 group than in control group and empty vector group on the 14th day after last injection (P <0.05).Conclusion:CD-40 si-RNA can reduce the concentration of IL-17,IFN-γand of anti-dsDNA antibody in serum,and at the same time,it can elevate the concentration of IL-4 and suppress CD40 mRNA and protein of spleen in MRL/Lpr.Meanwhile after suppressing CD40 mRNA and protein,it can reduce inflammatory response of the mice and the disease activity of MRL/Lpr,suggesting that CD-40 siRNA has therapy effect on SLE.

Objective To investigate the differences in clinical efficacy and safety between thrombolysis followed PCI (percutaneous coronary intervention) and primary PCI in patients with acute STEMI (ST elevation myocardial infarction). Methods A total of 215 STEMI patients who visit our clinic within 12 h since onset of their symptoms from May 2013 to January 2015 were enrolled. All eligible patients were divided into Early PCI group(n=68) and pPCI group (n=147) based on whether or not they received injection of recombinant human prourokinase thrombolytic therapy before their visit. Immediate TIMI (Thrombolysis In Myocardial Infarction) flow grade of infarct-related artery (IRA) before and after PCI treatment, post?operative CTFC (Corrected TIMI Frame Count) and TMPG (TIMI myocardial perfusion grade) were compared between these two groups. The incidence of bleeding during hospital stay , left ventricular function at 6 month after intervention and major adverse cardiac events (MACE) were all observed. Rusults There is no obvious difference between the baseline of two groups. Before PCI, the proportion of TIMI grade 2-3 was higher in Early PCI group (77.9%vs 20.4%,P<0.05)than that in pPCI group;but there was no significant difference in the proportion of TIMI grade 2-3 between these two groups after PCI (P>0.05). CTFC and peak value of serum CK-MB were lower [(27.7 ± 5.0) vs (32.6 ± 7.1), P<0.05;(225.8 ± 108.3) U/L vs (283.4 ± 110.6) U/L, P<0.05] and rate of TMPG 3 is higher (82.4%vs 68.7%, P<0.05)in Early PCI group than those in pPCI group. No significant difference was found in the incidence of bleeding and MACE during hospital stay and Left ventric?ular function at 6 months after operation between these two groups. By contrast, LVEFs were higher while LVEDds (LVED diameter) were lower after 3 and 6 months of the intervention compared to those before intervention in both groups (P <0.05). Conclusion It is a safe and effective reperfusion strategy for STEMI patients to receive rhPro-UK thrombolytic thera?py followed early PCI as an alternative way to those who failed to receive pPCI on time. It didn′t increase the occurrence of bleeding complications and MACE, and at the same time it presented the same benefit in improving recent cardiac function as pPCI did.

Pang Zanxiang was a famous ophthalmologist of Chinese medicine. Based on his family experience and combined with his clinical practice, he has written the book Clinical practice of ophthalmology in traditional Chinese medicine. In the book, the theory of stagnation of Qi and blood leading to disease was put forward, and radix stellariae was used most frequently in treating eye disease. From literature interview, we found that pang’s experience of radix stellariae in treating eye disease was its function of replenishing vital essence to improve eyesight.

Objective To investigate thc cvent-based prospective memory (EBPM)and time-based prospective memory(TBPM)in the inpatients with abstinent alcohol dependence and the relationships between prospective memory and symptoms.Methods 32 male patients with alcohol dependence and 30 normal controls matched by age,education,HAMD and HAMA were assessed with a neuropsychological battery of tests including EBPM and TBPM tasks.Results A statistically significant in EBPM was observed between patients with alcohol dependence and normal controls (3.91 ± 0.69 vs.4.47 ± 0.63,t =-3.348,P ＜ 0.0 1) and the same result in TBPM (3.28 ±0.77 vs.4.20 ±0.66,t=-5.032,P＜0.01).The positively correlation was showed between the duration of abstinence and EBPM (r =0.444,P ＜ 0.05),as well as TBPM (r =O.423,P ＜ 0.05) in the patients.Conclusion The results suggest abstinent alcohol dependence patients impairs both EBPM and TBPM.PM shows correlated with duration of abstinence moderately in the patients.

Objective:To explore the short-term and long-term prognostic outcomes of anatomical liver resection(AR)for patients with perihilar cholangio-carcinoma. Methods:This is a retrospective study.All data were obtained from 4 centers,including The First Affiliated Hospital of Army Medical University,Eastern Hepatobiliary Hospital of Naval Medical University,Sichuan Provincial People's Hospital and Affiliated Hospital of Qinghai University,of a multi-center database.A total of 305 consecutive perihilar cholangiocarcinoma patients receiving radical resection between January 2013 and June 2021 were included in this study.According to the method of liver resection,all patients were divided into the AR group(n=205)and the non-anatomical liver resection(NAR)group(n=100).The baseline characteristics,short-term prognosis and long-term prognosis of the 2 groups were compared. Results:The perioperative transfusion rate and the 30-day complication rate were significantly lower in the AR group than those in the NAR group(P＜0.05).There was no statistically significant difference in the survival rates between the AR and the NAR groups(P＞0.05). Conclusion:The 2 hepatic resection modalities had no obvious effect on the long-term prognosis of perihilar cholangiocarcinoma patients after radical resection,but choosing AR tends to achieve a better short-term prognosis and is worth promoting in clinical practice.
