Purpose:To analyze the CT appearances and diagnostic value of inflammatory pseudotumor of the liver(IPL)_O Materials and Methods: The CT findings of 19 patients with inflammatory pseudotumor of the liver proved by pathology were analyzed respectively.Results: 17 cases were solitary lesion and 2 cases had multiple lesions.19 lesions showed hypodense,2 lesions isodense on pre-contrast.On the contrast CT scan,showed no enhancement during arterial phase,but during portal venous phrase and delayed phase,strong enhancement at the edge and septa in the center or mural node,of the lesions were visible.Conclusion: CT diagnosis is possible in most cases of IPL by three phase dynamic scanning.

The value of surgery in the diabetes mellitus treatment receives much attention in the medical field,however,Chinese metabolic surgeons adopt the surgical experience from surgeries for morbid obesity in western countries.There are many controversies on the operative indication,operation method and postoperative follow-up of surgery for diabetes mellitus with low body mass index (BMI).Our nation has a large number of patients with diabetes mellitus and low BMI,in which uncheckedoperative indication,unstandard operation method and non-systematic follow-up are common problems.It has profound significance to investigate operative indication,operation method and efficacy evaluation for patients with diabetes mellitus and low BMI.

Objective: To develop methods for determining the disintegration time of oral disintegrating tablets (ODTs) of Chinese herbal drug, and to select the evaluation method with good reproducibility, resolving power, and in vivo and in vitro correlation. Methods: Several placebo ODTs and Chinese herbal drug ODTs were prepared. Their in vitro disintegration time was determined by self-developed method and routine methods, and the results were compared with the oral disintegration time. The reproducibility, resolving power, and the correlation between in vivo and in vitro of those methods were evaluated. Results = Different determination methods obtained different disintegration results of the same tablet. Graduated cylinder and improved disintegration apparatus both had shortcomings and their determination results were very different from that of the oral disintegration time. Our self-developed disintegration device could better determine the disintegration ability of the ODTs, and the result was closer to the oral disintegration time, with clear end point of disintegration and better reproducibility, resolving power, and the in vivo and in vitro correlation compared with other methods. Conclusion: Our self-developed device is suitable to determine in vitro disintegration time of ODTs, and may serve as a reference for quality control of ODTs.

Objective To explore and establish the effective model of assessment for residen-cy training. Methods Totally 181 residents completed general specialist stage of resident training of Liaoning province in 2010. Assessment process was designed and implemented for general specialist training stage, including theory exam (basic knowledge, professional knowledge and public knowledge) and objective structured clinical examination (OSCE) (standardized patient(SP), computer-based case simulations(CCS) and clinical skills operation). T test and variance analysis were used and P≤0.05 stands for statistically significant difference. Results The total results consisted of two parts, theory examination results (40.00%) and OSCE results (60.00%) and two students failed the examination. The mean score of OSCE was up to standard (66.58±5.50). The mean score of SP and CCS was close to standard. The mean score of clinical skills operation reached a good level. In terms of the OSCE, SP examination and CCS examination, the performance of residents from the two universities had sig-nificant difference (t=3.818, P=0.000; t=5.581, P=0.000; t=5.419, P=0.013) and the performance of residents from the five hospitals also had significant differences. Conclusions The assessment of standardized resident training is improving gradually. Through the widespread application of OSCE in the assessment;it could be helpful to the clinical training of residents.

Despite the progress in the comprehensive management of colorectal cancer,locally advanced (T3 and T4 stages) and metastatic colorectal cancer is still a challenging problem.Although researches on neoadjuvant therapy and targeted therapy have obtained many encouraging results,many unanswered questions still remain.These include the indication of multivisceral resection for locally advanced colorectal cancer,the optimal management of patients with hepatic and (or) pulmonary metastasis.R0 resection was the first choice for the treatment of metastatic colorectal cancer,but it is only suitable for selected patients.Chemotherapy and targeted therapy are effective in converting some unresectable liver metastasis into resectable disease.This review focuses on recent improvements in the management of locally advanced colorectal cancer,as well as the management of hepatic and (or) pulmonary metastasis.

Objective To study the pathological characteristics of allied Hirschsprung's disease (allied HD) by using NSE and S-100 protein immunohistochemical markers techniques,improve the early diagnosis rate. Methods 97 cases with HD were included in this study.The morphological and numeral change of the neuron and ganglion cell of the lesions was observed and compared with the normal controls.NSE and S-100 protein immunohistochemical markers were performed in 21 cases.Result The number of the neuron and ganglion cell of allied HD was statistically significantly higher than those in the normal control or HD group (P

Objective To evaluate VISER as a non invasive monitoring of penile cavernosal pressure for the diagnosis of ED. Methods With the use of AVSS and papaverine ICI,39 cases,including 32 patients of ED and 7 controls,were tested with VISER device. Results 7 controls and 13 ED cases (40%) have achieved a valid erection by AVSS alone while another 13 ED cases required papaverine ICI (10 mg) for successful erection whereas 6 of ED cases failed what so ever. The VISER testing showed the erection data and peak data indexes, especially in total energy of erection and peak, were higher in controls than ED groups except the average duration of erection being longer in ED papaverine group. Conclusions VISER is an accurate system for measuring the changes of intracavernosal pressure in dynamic state during penile tumescence. The use of eye glasses TV monitor can help enhance the effectiveness of AVSS and lower the dosage of vasoactive drugs.VISER testing is non invasive,accurate and easy to perform and might serve as a screening test for ED patients in the near future.

Stage assessment is an important part of standardized resident training.After two years of practice and exploration,Liaoning had established the complete examination and evaluation system including the theory test and skill test and this system was future improved through analyzing two years' results and summing up the experiences making it more suitable for residency training in the future.

Objective To analyze the features of cutaneous lesions and age of onset of tuberous sclerosis(TS).Methods A total of 54 TS patients were recruited;their clinical data were analysed.Results The occurance of facial angiofibromas,periungual fibromas,hypomelanotic macules and shark macules was 72.5%,26%,70%and 48%,respectively,and the median age of onset of these lesions was 7,14,0.2 and 6 years,respectively,with a peak at 1-9,10-19,＜1 and 1-9 years,respectively.Conclusions Cutaneous lesions are commonly seen in TS,and most of them develop early in life.
