OBJECTIVETo observe and compare the quality of life (QOL) and survival time in patients with advanced primary hepatic cancer (PHC) after they have been treated by the combination of ganji recipe and interventional therapy with Fructus Bruceae Oil Emulsion (FBE) or by the trans-hepatic arterial chemical embolization (TACE) adopting Seldinger's technique.

METHODSSeventy-seven patients with advanced PHC were randomly assigned to two groups, 37 patients in the control group treated with TACE alone, and 40 in the treatment group with the combined therapy. One therapeutic course was 4 weeks, and the intervention therapy was repeated generally after an interval of 4-6 weeks according to patients'condition ,the average intervention frequency was 2.3 for one case. The QOL and the survival time in patients were evaluated after treatment.

RESULTSSignificant difference was shown in the changes of the Karnofsky score between the two groups (P < 0.05). The scores suggested that the improvements in the treatment group, including patients'physical energy enhancing, symptoms alleviating and overall QOL improving, were superior to those in the control group (P < 0.05). No significant difference of the 3-month survival rate between the two groups was found (P > 0.05), but the 0.5- and 1-year survival rate were significantly superior in the treatment group to those in the control group (67.6% vs. 42.4% and 38.2% vs. 16.1%, respectively). The median survival time in the two groups was 8.9 and 5.3 months respectively.

CONCLUSIONCombination of ganji recipe and interventional therapy with FBE in treating PHC could improve patients' QOL, raise the 0.5- and 1-year survival rate, and prolong the survival time, suggesting TCM treatment has an affirmative significance for enhancing the therapeutic efficacy and improving the prognosis in patients.

OBJECTIVETo evaluate the relationship between allergic symptoms and retinoic acid-related orphan receptor variant 2 (RORC2) and interleukin (IL) 17 in patients with allergic rhinitis (AR).

METHODSBlood sample, nasal secretion and nasal mucosa were taken from 23 patients with AR and 16 health individuals. The expression of RORC2 and IL-17 were detected by immunohistochemistry and quantitative real-time fluorescence reverse polymerase chain reaction. The allergic symptoms in patients were graded.

RESULTSThe rate of positive cells of RORC2 and IL-17 in AR group were 0.17 ± 0.05 and 0.72 ± 0.13, higher than the 0.05 ± 0.02 and 0.27 ± 0.11 of health controls, the difference was statistically significant (t were 9.51 and 11.92 respectively, all P < 0.05). The expression level of RORC2 mRNA in nasal mucosa and peripheral blood of AR group were 0.063 ± 0.011 and 0.452 ± 0.031, higher than the 0.029 ± 0.009 and 0.239 ± 0.027 of health controls, the difference was statistically significant (t were 6.51 and 3.35 respectively, all P < 0.05). The concentrations of IL-17 in the nasal mucosa, nasal secretions and serum levels of AR group were (70.28 ± 10.69), (45.32 ± 8.55) and (6.76 ± 1.18) pg/ml, compared with (18.43 ± 8.34), (6.83 ± 1.31) and (0.74 ± 0.05) pg/ml of controls, the difference was statistically significant (t were 7.92, 17.66 and 15.43 respectively, all P < 0.05). The allergy symptom scores of AR group were 9.43 ± 1.27. There were correlations between the allergic symptom and the expression of RORC2 mRNA and IL-17 in nasal mucosa and peripheral blood (r value were 0.820, 0.746, 0.629, 0.841 respectively, all P < 0.05).

CONCLUSIONRORC2 and IL-17 involved in the inflammatory response of AR and can be used as an indicator to judge the severity.

Methods In this study 67 patients of portal hypertension undergoing surgery were randomly divided into two groups,receiving respectively intraportal vein heparin injection by 100 U?kg~(-1)?d~(-1)?7 d in group A (32 patients)and placebo in group B(35 patients).Portal vein thrombosis,the recurrent bleeding after operation and portal hypertensive gastropathy were compared between the two groups.Results The occurrence of portal vein thrombosis after operation in group A(0)was significantly lower than that in group B(20%,X~2=5.169,P

OBJECTIVETo investigate the correlation between subaxial cervical spine instability and cervical spondylotic sympathetic symptoms as well as the difference of cervical spondylotic subaxial instability between male and female patients.

METHODSWe analyzed retrospectively 318 surgical cases of cervical spondylosis treated at Department of Orthopedic Surgery of Peking Union Medical College Hospital between July 2003 and December 2007. All cases were divided into group A without sympathetic symptoms (n=284) and group B with sympathetic symptoms (n=34). Angular and horizontal translation values between two adjacent vertebral bodies from C2 to C7 were measured separately on hyperflexion and hyperextension lateral cervical spine radiographs. Fisher's exact test was used to evaluate the correlation between subaxial cervical instability and sympathetic symptoms. Intragroup correlation between patient gender and subaxial cervical instability was also evaluated.

RESULTSSubaxial instability incidences in groups A and B were 21.8% (62/284) and 55.9% (19/34), respectively. Statistical analysis indicated a definite correlation between subaxial cervical instability and sympathetic symptoms (P=0.000). Among patients without sympathetic symptoms, subaxial instability incidences were 21.4% (37/173) in males and 22.5% (25/111) in females, respectively (P=0.883). While among patients with sympathetic symptoms, subaxial instability incidences were 27.3% (3/11) in males and 69.6% (16/23) in females, respectively, indicating significant difference (P=0.030). Subaxial instability was most commonly seen at C4-C5 intervertebral space in sympathetic cervical spondylosis patients.

CONCLUSIONSHigh correlation exists between subaxial cervical spine instability and cervical spondylotic sympathetic symptoms, especially in female patients. Hyperextension and hyperflexion radiographs of cervical spine are important to assess sympathetic cervical spondylotic subaxial instability.

Objective To investigate the status of psychological quality of college students ' innovation and entrepreneurship, identify the elements of the psychological quality and problems and countermeasures against the psychological quality training in medical schools. Methods A questionair was made and administered to Kunming Medical University students and Chi-square analysis was used to analyze the gender, major, grade, and entrepreneurial intention differences between different groups of students so as to analyze the psychological factors affecting College students ' undertaking intention. Results A total of 1150 questionnaires,1099 was recovered,the effective recovery rate was 95.6％. Psychological quality score was (76.9 ±9.0), good mental qualities only was 8.2％, entrepreneurial environment, factors of psychological quality of good-willed persons were only 0.5％and 15.5％. Female entrepreneurial intentions were better than those of men (<0.001) . Science students' undertaking intention was superior to liberal arts students ( =0.025), knowledge of entrepreneurship difference between knowledge of business groups and <0.005,there was a statistically significant difference, about the environment worse group entrepreneurial intention superior knowledge of business groups. Conclusions As students' psychological qualities are poor,have poor psychological quality,in teaching we should strengthen the cultivation of medical students' entrepreneurial ability and correct understanding of entrepreneurship, create a good business environment, increase the entrepreneurship policy advocacy efforts, and create a good business environment and atmosphere so as to strengthen the entrepreneurship education, improve entrepreneurship courses so that students fully understand the cognitive and psychological qualities, stimulate the entrepreneurial motivation, lay the Foundation for entrepreneurship.

Objective:To understand the nutritional risk in patients with IBD,its related factors and nutritional treatment options.Methods:IBD patients treated in Peking University first hospital from January 2006 to December 2015 were studied.Using the Nutritional risk screening 2002 (NRS2002) nutritional risk assessment of the patients were evaluated.According to the body mass index (BMI),patients were divided into normal BMI group (BMI 18.5 ～ 23.9),low BMI group (BMI ＜ 18.5) and high BMI group (BMI ≥ 24).We analyzed the nutritional risk related factors and compared the difference of nutritional therapy options,regarding the UC and CD patients respectively.Results:A total of 388 patients with IBD were enrolled in the study,with UC 306 and CD 82 patients.The total nutritional risk was 49.5％.Although there was no difference in BMI distribution between UC and CD,CD was more likely to have nutritional risk than UC (CD 64.6％,UC 45.4％,(P =0.002).The nutritional risk of low BMI group was 95.7％.There were no differences in age,sex,and family history in IBD patients for the occurrence of nutritional risk.The more frequently recurrence,severe of disease activity,and the wider rang of disease bring the higher nutritional risk for UC patients.But for CD patients,penetrating type,having a history of surgery and severe of disease activity had higher nutritional risk.Adequate caloric nutrition therapy in patients with CD was 77.4％ higher than that of UC 46.8％,(P ＜ 0.001).It was a main principle of our center that UC patients with severe recurrence should not emphasize enteral nutrition and CD patients should first deal with the contraindications before starting enteral nutrition.Conclusions:IBD patients have a high nutritional risk and CD is more obvious than UC,particularly in low BMI patients.The nutritional risk of patients with UC and CD has its own associated factors.It is safe to treat IBD patients with enteral nutrition as long as the indications and contraindications were well controlled.
