Objectives To discuss mental health of fresh graduate students in China Academy of Chinese Medical Sciences (hereinafter referred to as our academy); To provide psychological basis for education and management of graduate students.Methods All 2014 fresh graduate students in our academy took psychological test via SCL-90 and comparison was made between this result and normal results of Chinese graduate students.Results The primary psychological problems of graduate students from our academy were shown as obsessive compulsive disorder (14.02%), interpersonal barriers (7.32%), depression (8.54%), and anxiety (5.49%). Among the freshmen, psychological health level of doctor candidates is higher than that of master candidates . Mental health of fresh TCM graduate students is better than that of national college students, with statistical significance (P<0.01). Conclusion Mental health of TCM graduate students is better. There is specificity for TCM students’ mental health maintenance. Therefore, health maintenance for TCM students should make full use of advantages in TCM major.

OBJECTIVEEvaluate the prognostic value of lymph node ratio (LNR) in patients undergoing resection of stage III colorectal cancer.

METHODSThe clinicopathological and follow-up data were collected from 174 surgical patients with stage III colorectal cancer. The 5-year disease-free survival (DFS) and overall survival (OS) were evaluated using Kaplan-Meier method. The impact of LNR and clinicopathological factors on DFS and OS were evaluated using univariate and multivariate analysis.

RESULTSAfter a median follow-up of 62.5 months, the 5-year DFS and OS of the patients were 51.8% and 56.3%, respectively. The median number of lymph nodes harvested and the median number of positive lymph nodes examined were 10 and 3, respectively. The patients were stratified into 4 groups according to LNR quartiles (LNR1, LNR≤0.125; LNR2, 0.1250.500), whose 5-year DFS and OS were 64.2%, 53.5%, 41.8%, and 25.7% (P<0.05) and 68.1%, 60.8%, 49.2%, and 32.7% (P<0.05), respectively. Multivariate analysis identified age, T stage and LNR as the independent predictors of both DFS and OS. Subgroup analysis showed that LNR had an independent prognostic value on DFS and OS irrespective of the number of lymph nodes harvested.

CONCLUSIONLNR is an independent prognostic factor for survival in patients with stage III colorectal cancer and is superior to the pN category in TNM staging.

Objective:To explore the impact of graft recipient weight ratio(GRWR)on pediatric whole liver transplantation in infants aged under 1 year.Methods:From January 2014 to December 2019, clinical data were retrospectively reviewed for 140 children aged under 1 year with whole liver transplantation.They were divided into 3 groups of low GRWR(GRWR<2.5%, 48 cases), middle GRWR(2.5%≤GRWR<5%, 73 cases)and high GRWR(GRWR≥5%, 19 cases). Basic profiles, major postoperative complications and survival rate of graft/recipient were compared.Results:There were 62 males and 78 females with an average age of (7.34±1.81)months and an average weight of(6.81±1.09)kg.The median GRWR was 3.27%(1.33%~8.12%). The higher level of GRWR, the greater age, weight and graft weight of donor in three groups and there was statistical difference ( P<0.05); operative duration, postoperative ICU stay and hospital stay were longer in low GRWR group than those in middle GRWR group and there was statistical difference( P<0.05); The incidence of postoperative hepatic artery thrombosis was higher in low GRWR group than that in middle GRWR group(31.3%vs 8.2%)and there was statistical difference( P<0.05); 4 cases of small-for-size syndrome occurred in low GRWR group, it was significantly different from the other two groups and there was statistical difference( P<0.05); the median follow-up period was(50.7±23.4)months.The survival rates of grafts at 3-month and 1/5-year were 89.6%, 91.8%, 100%; 87.5%, 87.7%, 100%; 87.5%, 87.7%, 100%and there was no inter-group difference( P>0.05). The survival rates of recipients at 3 months, 1 year and 5 years post-operation were 93.8%, 91.8%, 100%; 91.7%, 87.7%, 100%; 91.7%, 87.7%, 100%and there was no inter-group difference( P>0.05). Conclusions:Different from pediatric living donor transplantation, GRWR≥5%does not affect the survival rate of recipient/graft during whole liver transplantation.And GRWR<2.5%may boost the postoperative incidence of hepatic artery thrombosis and small liver syndrome.

OBJECTIVE: To investigate the B lymphocytes(CD20) and T-lymphocyte subsets (CD4, CD8) expression and clinical significance in chronic rhinosinusitis. METHOD: Immunohistochemical technique was applied to detect the expression of the B lymphocytes (CD20), helper T lymphocytes (CD4) and the cytotoxic T lymphocyte (CD8) in 15 patients with chronic rhinosinusitis without nasal polyps group (CRSsNP). 12 patients of chronic nasal sinusitis with nasal polyp (CRSwNP), 7 cases of recurrent CRSwNP group and 13 patients with inferior turbinate mucosa in the control group. The Mann-Whitney U test was used to analyze CD)20, CD4 and CD8 between the experimental groups and the control group. One- Way ANOVA was used to compare the lymphocyte infiltration between the experiment groups. RESULT: Patients with CRS had higher infiltration of the B lymphocytes (CD20) and T lymphocyte subsets (CD4, CD88) than the patients of the control group (P < 0.05). The expression of T lymphocyte subsets (CD4, CD8) in CRSwNP and recurrent CRSwNP groups was significantly higher than in CRSsNP (P < 0.05). The expression of CD4 in the recurrent CRSwNP group was obviously higher than that in CRSsNP and CRSwNP (P < 0.01). CONCLUSION The B lymphocytes, helper T cells and cytotoxic T cells have the high expression in CRS groups, which involved with the formation of inflammation. Furthermore nasal polyps are closely related to T lymphocyte infiltration.
