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)

The paper analyzes the necessity to construct the digital resources retrieval platform in hospital.By using heterogeneous database integration technology, it proposes the solution of constructing a one-stophospital digital resources retrieval platform and presents its framework.This retrieval platform can provide human-oriented, differential and intelligent information services and meet the medical staffs'requirements on information resources retrieval to the greatest extent.

Some ideas were proposed on establishing the mobile medical information service system by relying on the communication platforms such as Wechat , microblog and hospital website , in order to provide mobile informa-tion service for medical staff .The functions of its information need access module , information source module and information transfer module were described in detail, and certain suggestions were put forward for its normal opera-tion, such as active popularization, attraction of its user groups, development of information service file database, establishment of incentive mechanisms , and construction of information service team.

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

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.

Postpartum inferior vena cava (IVC) thrombosis is a rare, but potentially life-threatening disorder. Here we reported one case of the youngest woman to date who presented with massive IVC thrombus extending from deep veins of the right leg to the level of the 11th thoracic vertebra, associated with asymptomatic pulmonary embolism.

In order to change the situations such as students’passivity and low enthusiasm in the traditional experimental teaching of Microbiology and improve students’comprehensive qualities,exploration and attempt on experimental teaching reforms including teaching contents,teaching modes,laboratory management and evaluation system of examination were done.Teaching practices showed that the normalized ex- periment syllabus based on the correct orientation of experimental teaching of Microbiology,the actualization of teaching mode of basic skill training-integrated experiment-designed experiment and the management of opening laboratory were effective measures in improving experimental teaching of Microbiology.

Objective To investigate the variation of lipid profile in patients with acute myocardial infarction (AMI) of different age groups.Methods Total 1214 patients of AMI were admitted to our hospital from May 2007 to July 2011.The age of patients ranged 40-89 years,and patients were divided into 5 age groups with 10-years step.Differences in lipid levels were observed by using pair-wise comparison among different age groups.Results Pair-wise comparisons among different age groups indicated that TC levels were higher in 40-69 years age groups [(4.71 ± 1.08),(4.80 ± 1.30),(4.69 ± 1.03) mmol/L,respectively] than those in the 70-89 age groups [(4.41 ± 0.96),(4.38 ± 1.03) mmol/L],all P ＜ 0.05(t values were 2.381,2.323,4.382,3.965,3.317,3.096).TG levels among three age groups ＜ 59 years had no significant difference,which were higher than those in groups over 60 years.Among 50-89 years age groups,TG gradually reduced with increase of age.HDL levels were lower in 40-59 years age groups [(1.03 ± 0.23),(1.05 ± 0.26) mmol/L,respectively] than those in 60-89 years age groups [(1.11 ±0.28),(1.11±0.28),(1.16±0.34) mmol/L,respectively],allP＜0.05 (t values were-2.777,-2.789,-3.731,-2.543,-2.566,-3.644).Total cholesterol (TC) (r =-0.123,P ＜0.01),lowdensity lipoprotein cholesterol (LDL) (r =-0.139,P ＜ 0.01) and triglyceride (TG) (r =-0.287,P ＜0.01) were negatively but high-density lipoprotein cholesterol (HDL) (r =0.125,P ＜ 0.01) was positively correlated with age of patients.TC levels in female patients were higher than those in male patients in 50-89 years age groups; LDL levels in female patients were higher than those in male patients in 50-69 years age groups and HDL levels in female patients were higher than those in male patients in 40-79 years age groups (all P ＜ 0.05,t values were-2.878,-3.007,-3.352,-3.333).Conclusions Results show that the non-elderly AMI patients (＜60 years) have higher levels of TC,LDL and TG,and lower level of HDL than the elderly patients; the TC,LDL and HDL levels are higher in female AMI patients than those in male patients at the same age groups.

Objective Establish a laboratory quality control system to ensure accurate and reliable test data and to contrapose the influence of error factors in current detection methods for urinary iodine measurement. Methods The results of reagent blank absorbance value and uric iodine standard materials were collected, then their relevant technical indexes such as mean, standard deviation, control limit, auxiliary line were worked out. Then the quality control chart of blank test and the relative error control chart were made base on these technical indexes. And different iodine concentrations (high, middle and low concentration) were tested and their mean,relative reduction difference value, weighted mean value and critical limit Rc value were calculated, and then critical limit Rc value precision control chart was made. Results The range of absorbance of blank control test was 1.183 to 1.553. And the limit of the accuracy control Rc value was 0.0883, 0.0572, respectively, when the concentrations of urinary iodine was 0～ < 150 μg/L and 150 ～ 300 μg/L. The control limit of the relative error was 9.3%. Conclusions The method of quality control chart could be satisfactorily applied to identify the quality of the analytical results of urine iodine, and ensure the results of the urine iodine reliable and authentic.
