Objective To explore the application of the comprehensive pain assessment scale to the treatment of postherpetic neuralgia (PHN). Methods About 100 patients suffering from PHN were randomly divided into two groups: the control group and experiment group. The former was treated with recording for pain assessment and the latter was treated with the comprehensive pain assessment scale. Two sets of data were compared and analyzed in view of quality of sleep, average length of hospitalization and the duration of side effects of drugs. Result The effect of the experiment group was better than the control group in the quality of sleep, the average length of hospitalization, reduction of side effect duration of drugs (P<0.05). Conclusion The comprehensive pain assessment scale throughout the whole process of the PHN treatment can achieve timely and effective assessment of pain and reduce the side effect duration of drugs, improve their sleep quality, and shorten the hospital stay.

The preservation of urinary proteins on a membrane plays a vital role in biomarker research, and the efficient elution of proteins preserved on nitrocellulose membrane (NC membrane) determines the application of this method. During the heating elution procedure, we raised the temperature to reduce the intense vortexing time, and kept gentle rotating while precipitation to prevent nitrocellulose reformation. We also used SDS-PAGE and LC-MS/MS to analyze the urinary proteins prepared by heating elution procedure, intense vortexing elution procedure and acetone precipitation method. There was no degradation of proteins prepared by heating elution procedure. Compared with proteins prepared by heating elution method and acetone precipitation method, the overlapping rates of the proteins was almost the same (92.6% versus 96.8%) and the ratios of CV values (< 20%) of the proteins were both high (85.2% and 94.4%). The heating elution procedure achieved good technical reproducibility, and was much simpler and more efficient than the previous one. It can facilitate the application of the preservation of urinary proteins on membrane.

ObjectiveTo assess the relationship between the location,quantity and leukodystrophy of cerebral infarction and vascular cognitive impairment ( VCI ),and to compare the differences of the severity and domains of cognitive impairment among the different types of cerebral infarction,which will provide the pathophysiological evidence to the mechanism for the development of VCI. MethodThe patients suffering from cerebral infarction or leukodystrophy were recruited from either the ward or clinic in Tianjin General Hospital from April 2009 to April 2010,then assessed the cognition,and classified into different groups according to the location,size,quantity,whether or not they have leukodystrophy and the severity.The Logistic regression analysis was taken with whether or not the patients have had developed to the VCI as the dependent variable,and with the location,size,quantity,whether or not they have leukodystrophy and the severity as the independent variables.The differences of the score of NIHSS,Bathel index and the level of cognitive impairment were compared among patients with different types of lesions.Moreover,the difference of the score of MoCA for each cognitive domain were compared among patients with different types of lesions.ResultsThere was a relationship between key position infarction in the subcortex and white leukodystrophy with VCI.The position infarction in the subcortex and white leukodystrophy ( grade Ⅱ and Ⅲ ) might be the independent risk factors for the VCI( OR =1.752,2.135,3.753; 95％ CI 1.533-3.821,1.541-6.787,1.432-6.821,all P ＜0.05).There were significant differences in the domains of excusive ability,attention,calculation,fluent language and orientation.The average scores of the domain of excusive ability in the subcortical group (3.40 ± 1.90) and the mix group (3.83 ± 1.27) were significantly lower than the cortical disease group(4.28 ± 0.89,t =0.050,0.857,both P ＜ 0.05 ).The average scores of the domains of attention,calculation,fluent and orientation in the mix group were significantly lower than the subcortical group and cortical disease group.ConclusionsThere is a significant association of the key infarction in the subcortex and leukodystrophy with VCI.The patients with both the subcortex infarction and leukodystrophy are susceptible to VCI.The development of VCI is depended on the position of infarction instead of the quantity and size of infarction.The development of VCI is not only related to the white matter disease but also related to the severity of the leukodystrophy.The data highlights the need to small vessel disease.The patients with subcortical lesions mainly impair the executive ability.The patients with mix lesions may have more extensive domains and more severe cognitive impairment.

Objective To introduce the super minimally invasive transintercostal device closure of ventricular septal defect (VSD) and summarize it's therapeutic effect.Methods Nine patiens with VSD from August 2014 to December 2014 in our hospital were enrolled,which performed super minimally invasive transintercostal device closure of VSD.All patients were followed up prudently post-operation.Echocardiography was scheduled according to the protocol.Results All cases were successfully occluded.There was no death case in the peri-operation period and severe complications after operation.Conclusions The super minimally invasive transintercostal device closure of VSD is safe and reliable.

Scientific research training program is an important component in the 8-year medical education program. It focuses on the training of scientific research thinking and research methods. It is necessary to establish an effective evaluation system in order to achieve the learning outcomes of scientific research training program. PUMC has established an effective evaluation system which involves research project selecting,supervising,formative assessment,oral defense. This paper introduces the evaluation system of scientific research training program at PUMC.

Objective To evaluate the heating ability of thermoseeds in alternating magnetic field and its therapeutic effects on tumor bearing rats with simultaneously detected immune function. Methods To monitor the temperature increase of thermoseeds in vitro,of which the Curie point was 57 ℃ or 70 ℃.Forty Wistar rats implanted with Walker-256 cells were randomly divided into five groups: C group(control group,10 rats),M group(magnetic control group,5 rats),T group(thermoseeds control group,5 rats) and two heating treatment groups(H1 group,10 rats and H2 group,10 rats).In the H1 group,two thermoseeds with a Curie point at 57 ℃ were implanted into the tumor tissues in each rat with a heating time of 30 minutes,while in the H2 group,two thermoseeds with a Curie point at 70 ℃ were used with a heating time of 6 minutes.Five rats from each group were killed 9 days after the heating therapy to evaluate the volume and weight of the tumor tissues.The peripheral blood T-cells were counted in the rest rats in the H1,H2,and C groups. Results Magnetic inductive heating of the thermoseeds in vitro can reach the Curie point.The median tumor volume in the H2 group was 0.50 cm3(0.00-26.54),which was significantly lower than that in the M group(36.18 cm3,0.96-39.90,Z=2.21,P=0.032).And the weight of the tumors in the H1 and H2 groups was significantly lower than that in the M group [0.96 g(0.00-21.18) in H1 and 0.41 g(0.00-23.40) in H2 vs 31.45 g(1.09-36.09) in M group,Z=2.21 and P=0.032 for both].In the peripheral blood,the percentage of CD4+ T-cells was(22.39?5.27)% in H1 group,and(24.76?5.19)% in H2 group,which were significantly higher than that in C group [(12.07?4.45)%,P=0.01 and 0.003 respectively];and the percentage of CD8+ T-cells in the H2 group was significantly higher than that in the C group [(19.58?4.63)% vs(12.72?3.96)%,P=0.04].Conclusions Thermoseed had a good heating ability in alternating magnetic field and its inductive heating can inhibit tumor growth in Wistar rats and improve the immune function of the rats.
