Objective To investigate the expression of NF-κB/p65 in nasal NK/T cell lymphomas. Methods Immunohistochemis-try and TUNEL were used to study the expression of NF-KB/p65 and cell apoptosis in 23 nasal NK/T cell lymphoma samples and 14 benign lymph node lesions. Results The NF-KB/p65 positive rates were 43.5% (10/23). The expression of NF-κB/p65 was negative correlated with apoptotic index among 23 nasal NK/T cell lymphomas(P <0. 05). The mean survival period in patients expressed NF-KB/p65 was sig-nificantly shorter than that in negative group(P <0. 05). Conclusions Apoptosis inhibited by overexpression of NF-κB/p65 might be in-volved in the development of nasal NK/T cell lymphoma. NF-κB/p65 expression may be an unfavorable prognostic factor of nasal NK/T cell lymphoma.

Objective To investigate the expression of XIAP and survivin and its significance in diffuse large B-cell lymphoma. Methods The expression of XIAP and survivin were detected by immunohistochemistry in 49 patients with diffuse large B-cell lymphomas. Results The positive rate of XIAP and survivin in cases of DLBCL were 40.8%(20/49) and 44.9%(22/49) respectively, which was higher than that of benign lymph node pathological changes (P ＜0.05). The expression of XIAP in DLBCL positively correlated with the expression of surviving (r =0.382, P =0.01). Moreover, the mean survival period in DLBCL expressing XIAP was shorter than the XIAP-negative group. Conclusion The up-regulation of expression of XIAP may play an important role in the development of DLBCL, and may cooperate with the expression of survivin in apoptosis pathway. Furthermore, the expression of XIAP might be a new unfavorable prognosis factor of DLBCL.

Objective To investigate the change of cardiac function in elderly hypertensive patients with heart valve degenerative by echocardiography.Methods A total of 126 cases were divided into a valve disease group and non-valve disease group groups.The parameters of trial size,cardiac function and pulmonary artery pressure were detected.Results Of all 126 cases were the patients with hypertension including 28.6% (36/126) of valve disease group and 71.4% (90/126) of non-valve disease.There were 31 cases with mitral valve disease,22 cases with tricuspid valve disease; 26 cases with aortic valve disease; 36 cases with double or three alvular lesions in valve disease group.There was a significant difference in ventricle size and systolic function among valve disease group and non-valve disease group and control group.But there was no significant difference in thickness of ventricular wall between valve disease group and non-valve disease group.Conclusion The elderly hypertensive patient with valve disease was an independent factor for the development of congestive heart failure.

Objective To evaluate long-term outcome of simultaneous kissing sirolimus-eluting stent (SKS) technique versus single sirolimus-eluting stent (SSS) technique for percutaneous treatment of true coronary bifurcation lesions in large-size vessels.Methods This randomized study assigned 190 patients with a coronary bifurcation lesion to simultaneous kissing stenting (SKS) in both main and side branches and 190 patients to main vessel stenting only (SSS).The endpoints included restenosis,death,non-fatal myocardial infarction,target-lesion revascularization (TLR),stent thrombosis,success rate of percutaneous coronary intervention (PCI) and the operation duration.Results During 1-year follow-up,the SKS group and the SSS group had similar incidences of overall re stenosis [30 ( 15.8 ％ ) vs.24 ( 15.2 ％ ),x2=0.000,P＜0.05],mainbranch restenosis [20 ( 10.5％ ) vs.16 ( 10.1％ ),x2=0.003,P ＞ 0.05];side-branch restenosis [13 ( 6.8％ )vs.23 ( 14.6％ );x2=4.73,P＜0.05];death [2 ( 1.1％ ) vs.1 ( 0.6％ ),x2=0.026,P ＞ 0.05],non-fatal myocardial infarction [4 (2.1％ ) vs.2 ( 1.3％ ),x2=0.034,P ＞ 0.05],TLR [23 ( 12.1％ ) vs.20 ( 12.7％ ),x2=0.000,P ＞ 0.05] and stent thrombosis [4 (2.1％ ) vs.2 ( 1.3 ％ ),x2=0.034,P ＞ 0.05] and a shorter operation duration[(20 ± 8) min vs.(45 ± 9) min,t=1.98,P＜0.05] than the SSS group.Conclusion For true coronary bifurcation lesions in large-size vessels,SKS and SSS have similar long-term outcomes.The SKS group has a higher success rate of PCI and shorter operation duration.

?AlM: To evaluate the clinical efficacy of posterior continuous curvilinear capsulorhexis ( PCCC ) combined with anterior vitrectomy in preventing posterior capsule opacification of congenital cataract surgery.
?METHODS:Postoperative clinical follow-up data of 82 cases ( 87 eyes ) with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group ( 38 cases, 40 eyes, recieved phacoemulsification + PCCC ) and the study group ( 44 cases, 47 eyes, accepted phacoemulsification+ PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow - up. lntraoperative and postoperative complications were observed.
?RESULTS:The rate of central optic axis opaque grade 0 in control group was 37. 5%, compared to 76. 6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group (P<0. 05). The 19 eyes(47. 5%) of visual acuity testing ≤0. 5 in control group , was higher than the 7 eyes(14. 89%) of that in the study group, The 21 eyes (52. 5%) of visual acuity testing >0. 5 in control group was lower than the 40 eyes ( 85. 11%) of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up ( P<0. 05 ) , and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups ( P<0. 05), but there was no significant difference between two groups in intraocular pressure (P<0. 05).
?CONCLUSlON: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.

The deubiquitinating enzyme ubiquitin specific peptidase 15 (USP15) is regarded as a regulator of TGFβ signaling pathway. This process depends on Smad7, the inhibitory factor of the TGFβ signal, and type I TGFβ receptor (TβR-I), one of the receptors of TGFβ. The expression level of USP15 seems to play vital roles in the pathogenesis of many neoplasms, but so far there has been no report about USP15 in psoriasis. In this study, immunohistochemical staining of USP15, TβR-I and Smad7 was performed in 30 paraffin-embedded psoriasis specimens and 10 normal specimens to investigate the expression of USP15, TβR-I and Smad7 in psoriasis and to explore the relevance among them. And USP15 small interfering RNA (USP15 siRNA) was used to transfect Hacat cells to detect the mRNA expression of TβR-I and Smad7. Of 30 cases of psoriasis in active stage, 28, 24 and 26 cases were positive for USP15, TβR-I and Smad7 staining, respectively. The positive rates of USP15 and Smad7 were significantly higher in psoriasis specimens than in normal skin specimens (44.1%±26.0% vs. 6.1%±6.6%, 47.2%±27.1% vs. 6.6%±7.1%), and positive rate of TβR-I (20.3%±22.2%) in psoriasis was lower than that in normal skin specimens (46.7%±18.2%). There was a significant positive correlation between USP15 and Smad7 expression, and significant negative correlations between USP15 and TβR-expression, an I d between TβR- and Smad7 expression I in psoriasis. After transfection of USP15 siRNA in Hacat cells, the expression of TβR-mRNA was up I -regulated and that of Smad7 was down-regulated. It is concluded that USP15 may play a role in the pathogenesis of psoriasis through regulating the TβR-I/Smad7 pathway and there may be other cell signaling pathways interacting with USP15 to take part in the development of psoriasis.

AIMTo study the effects of TNF receptor blocking peptide on adjuvant arthritis in rats.

METHODSThe model of rat adjuvant arthritis was induced by injection of complete Freund's adjuvant. The TNF receptor blocking peptide was injected locally in the ankle. The ankle swelling, the pathologic changes in the ankle joint and the expression of IL-1 beta mRNA and TNF-alpha mRNA by peritoneal macrophages (RT-PCR) were observed.

RESULTSThe model of rat adjuvant arthritis induced by injection of complete Freund's adjuvant was similar to human rheumatoid arthritis. The treatment with TNF receptor blocking peptide for 10 days resulted in complete inhibition of joint swelling, a decrease in infiltration of inflammatory cell into joint tissue, an obvious alleviation of inflammatory pathological damages and an apparent decline of TNF-alpha mRNA and IL-1 beta mRNA of peritoneal macrophages of rats.

CONCLUSIONThe TNF receptor blocking peptide can protect the joint from inflammatory damage induced by adjuvant arthritis by suppression of TNF-alpha and IL-1 production, thereby alleviating the pathological injury of joint and controlling effectively the clinic course of arthritis.

To reveal the characterization of interaction between Chinese and western medicinal injections, isothermal titration calorimetry (ITC) was applied to evaluating the interaction of Yiqi Fumai injection (YQFM, as mode drug) with epinephrine hydrochloride injection (YS) and 5% glucose injection (5% GS). The diversification of Gibbs free energy (ΔG), enthalpy (ΔH), and entropy (ΔS) were determined to judge the reaction types of colliquefaction procedures of different injections. Meanwhile, the fingerprints of YQFM before and after combined with the various injections were compared to validate the results. This work demonstrated that during the titration procedure of YQFM and YS, [ΔH] > T [ΔS] , that was to say the reaction was enthalpy-driving. And the reactive profile indicated that a great deal of heat gave out during the procedure. Obviously, chemical reactions happened and the internal component changed. On the other side, the reaction of YQFM combined with 5% GS was entropy-driving, because [ΔH] < T [ΔS]. The reactive profile showed there was only a little heat released. So non-chemical reactions happened and the major ingredients did not change. ITC could be applied to the evaluation on compatibility of other kinds of Chinese and western medicinal injection combination.

Intraoperative awareness is a very serious complication of general anesthesia.Several studies have evaluated the potential association between bispectral index (BIS) and intraoperative awareness,however,the results obtained were controversial.Therefore,we performed a meta-analysis to further assess the association between the BIS monitoring and the incidence of intraoperative awareness.A comprehensive search was conducted to identify all eligible studies from the online literature databases published prior to Feb.2017.A total of five studies with 17 432 cases and 16 749 controls were included.An odds ratio (OR) and a 95％ confidence interval (CI) were calculated to examine the strength of the association.The results showed that in the overall analysis,the association between the BIS monitoring and the incidence of intraoperative awareness was not significant (OR=0.58,95％ CI=0.22-1.58,P=0.29).A stratified analysis by comparing different anesthesia methods revealed that BIS monitoring group showed a lower incidence of intraoperative awareness in patients with intravenous anesthesia when compared with non-BIS monitoring group (OR=0.20,95％ CI=0.08-0.49,P=0.0004),whereas there was no statistically significant difference in the incidence of intraoperative awareness between BIS and non-BIS monitoring groups in patients with inhalation anesthesia (OR=1.13,95％ CI=0.56-2.26,P=0.73).In conclusion,our meta-analysis showed that BIS monitoring had no appreciable advantage in the reduction of the intraoperative awareness incidence in inhalation anesthesia,while showed a remarkable superiority in intravenous anesthesia.
