1.Effects of diltiazem on angiographic and clinical outcomes in patients with chest pain following coronary stenting
Journal of Interventional Radiology 2001;0(05):-
Objective To evaluate the effects of diltiazem on angiographic and clinical outcomes in patients with postprocedural chest pain after coronary stenting. Methods Two hundred and fifty-one patients with postprocedural chest pain were divided into two groups: diltiazem group (n = 189) and control group (n = 62). The outcomes of the two groups were compared according to the following two points. The first point was the major adverse cardiac events, including mortality, nonfatal infarction and target lesion revascularization. The second point was restenosis during the follow-up period. Results By the median of 128 days, the severe composite clinical events reached 4.8% in the diltiazem group and at 12.9% in the control group (P = 0.039). Repeated angiography was performed in 42.6% of these patients within one-year showing 11.5% restenosis in the diltiazem group and 29.2% in the control group (P = 0.05). Conclusions In patients with postprocedural chest pain after coronary stenting, oral diltiazem contributes a favorable outcome. (J Intervent Radiol, 2006, 15: 261-263)

AlM:To discuss the clinical effect and safety of the combined surgeries of phacoemulsification and goniosynechialysis for patients with primary angle -closure glaucoma ( PACG) .METHODS:Eighty-three eyes of 83 patients with PACG and cataract were ranomized into two groups. Group A:39 patients with 39 eyes of angle-closure <180.;Group B:44 patients with 44 eyes angle - closure ≥180.. The changes of visual acuity, anterior chamber depth ( ACD) , anterior chamber angle and lOP after operation were measured. The follow-up period was for 1a.RESULTS: The visual acuity was improved significantly in both group after operation. No significantly difference in ACD, anterior chamber angle after operation in two groups (P>0. 05). The lOP in group A was lower than that in group B 3mo after operation, there was statistical significance (P<0. 05).CONCLUSlON:Phacoemulsification and goniosynechialysis can deepen ACD significantly. This method make the anterior chamber angle open, can reduce lOP and improve the patients’ visual acuity, especially in patients with PACG. lt is a safe and effective approach to patients with PACG and cataract.

Objective To study the effect of nerve growth factor on airway inflammation and Th1/Th2 cells immune imbalance.Methods(1)32 SD rats were divided into 4 groups randomly:asthma,control,NGF,anti-NGF-antibody groups.The asthmatic model were established by inhalation and injection of ovalbumin.(2)We investigated the expression of NGF mRNA in the lungs in asthma and control groups by reverse transcription-polymerase chain reaction(RT-PCR).(3)In the lungs of the four groups,the expression of interferon-?(IFN-?,one of the Th1 cytokines),interleukin-4(IL-4,one of the Th2 cytokines)mRNA was detected by RT-PCR too.Results(1)As compared with the control group,NGF mRNA was significantly enhanced in the asthma group[(90.4?7.6)% vs(51.8?12.3)%,P

Objective To explore the underlying anatomy of iliac vein compression syndrome (IVCS) using CT, and discuss the imageological index for subtype diagnosis and potential clinical significance. Methods We retrospectively analyzed the imageological data of 69 IVCS patients from July, 2009 to June, 2014. According to CT findings, patients were categorized to simple IVCS (sIVCS, the iliac vein is compressed by only the anterior iliac artery, n=22), lumbar degeneration?related IVCS ( dIVCS, besides the iliac artery, the lower lumbar degenerative changes including osteophyte, protruded disc, etc. pressed the iliac vein from the back, n=33) and other IVCS causes (oIVCS, including tuberculosis, inflammation and fracture hematoma of the lumbar spine, n=14); meanwhile, 69 age? and sex?matched subjects was set as a control group. Evaluated indexes were onset age, course of lower limb swelling and pain, size of the iliac vein tunnel ahead lumbar (IVTAL), lower lumbar spine forward curvature angle (LLSCA), iliac vein?pressed signs by lower lumbar degeneration, compression sites, scope of deep venous thrombosis and interventional therapeutic effect. The differences of those indexes of various groups were compared. Data as onset age, course of disease, sizes of IVTAL and LLSCA were evaluated using variance analysis of the general linear model, with Bofferroni test correction for multiple comparisons. Data as iliac vein?pressed site, scope of venous embolism and therapeutic effect were assessed by crossing table χ2 test. All statistical analyses were performed using SPSS17.0 software (SPSS company, Chicago, USA). Bilateral P≤0.05 were considered to be significant. Results The onset mean age was (61.5 ± 10.6) yr. in dIVCS, (42.3 ± 6.5)yr in sIVCS. and(53.1 ± 16.8)yr. in oIVCS with a significant difference ( F=11.030, P<0.01). Mean sagittal diameter of the IVTAL and LLSCA were(2.3±0.5)mm and(121.8±5.4)° in dIVCS and(2.5± 0.5)mm and(124.4 ± 3.9)° in sIVCS, respectively; which were smaller than those of control group [(6.4 ± 1.6)mm and(127.5 ± 7.3)° , respectively ] and oIVCS [(5.9 ± 2.3)mm and(129.5 ± 5.9)° , respectively ](F=125.275,P<0.01 for sigittal diameter and F=7.95,P<0.01 for LLSCA). The degenerative changes compressing the iliac vein of dIVCS had 41 sites of 33 patients which were respectively the discal forward protrusion or bulge (51%, 17/33), vertebral anterior osteophyte (50%, 16/33)and lower lumbar vertebrae slippage (19%,8/33). The compression sites of dIVCS located exactly anterior to the fifth lumbar(18/33, 56%), the intervertebral disk between the fourth and fifth lumbar(9/33, 26%), the right front (3/33, 9%) and left front (3/33, 9%) of the fifth lumbar, however, that of sIVCS sited the right front(14/22, 64%), exactly the front(4/22, 18%)of the fifth lumbar and exactly anterior(4/22, 18%)to the intervertebral disk between the fourth and fifth lumbar, with a significant difference of location distribution(χ2=19.305, P<0.01). In sIVCSs, deep vein thrombosis of all exceeded the iliac vein length and implicated the femoral vein by 27%(6/22)and the popliteal vein by 73%(16/22), while in dIVCSs 18%(6/33)patients had deep vein thrombosis in the iliac vein, 30%(10/33)in the femoral vein and 52%(17/33)in the popliteal vein, and in oIVCSs, 30%(4/14)patients had deep vein thrombosis in the iliac vein, 40%(6/14)in the femoral vein and 30%(4/14)in the popliteal vein, with a significant difference of thrombosis scope(χ2=9.28, P<0.01). 86%sIVCSs needed intravenous stent?implanted operation to obtain effective treatment, only 52%dIVCSs were performed stent?implanted operation for effective therapy, none of oIVCSs had stent?implanted operation before the iliac vein recanalization. Conclusion CT can precisely display the pathological anatomy features of different IVCS patients, which can potentially help clinicians plan accurate treatment strategy.

Aim To improve the sensitivity of phycobiliprotein immunofluorescence assay(PBPIFA), by introducing into bridged avidin biotin(BRAB) technique,known as BRAB-PBPIFA. Methods Using ELISA as a gold standard, effectiveness of three assays(direct PBPIFA, BRAB-PBPIFA and ELISA)were compared in simultaneous detection of standard antigen and 500 serum samples. Results BRAB improved greatly sensitivity of PBPIFA in detecting antigen of low concentration, and detection rate of weakly positive samples could increase by one times and a half. In the applying, protein-free blocking agent Tween 20 to BRAB-PBPIFA,possessed better blocking effect. Conclusion Combination of BRAB technique with PBPIFA can improve the detcctive sensitivity.
