Objective To explore the distribution characteristics and regularity of traditional Chinese medical (TCM) syndromes in patients with sepsis in Department of Emergency of our hospital by enalyzed their clinical data and TCM four clinical diagnostic information so as to provide the basis for TCM standardized diagnosis and treatment of sepsis. Methods From July 2016 to October 2017, 135 patients with sepsis were admitted to the Department of Emergency and Department of Emergency Intensive Care Unit (EICU) of the First Affiliated Hospital of Zhejiang Chinese Medical University, 110 cases in sepsis group, 25 cases in sepsis shock group. An unified questionnaire was developed to collect the patients' general data, infection site and TCM four clinical diagnostic information (TCM syndromes, tongue coating, pulse signs, etc.) for dialectical typing on the day of admission with definite diagnosis, the relevant laboratory examinations were completed within 24 hours after the confirmative diagnosis was made, and the quick sequential organ failure assessment (qSOFA) and SOFA scores were calculated. Results In 135 cases of sepsis, pulmonary infection (51.9%) was the main one, followed by abdominal infection (25.9%). The distribution of TCM syndromes: the toxic heat syndrome was the main syndrome in sepsis group (61.8%) and acute deficiency syndrome was the main syndrome in sepsis shock group (68.0%), the difference between the two groups being statistically significant (P < 0.001). There were no statistical significant differences in comparisons of infection related indicators between sepsis and septic shock groups, different TCM syndromes of sepsis (all P > 0.05), such as white blood cell count (WBC), percentage and absolute value of neutrophils, C-reactive protein (CRP), procalcitonin (PCT). the lactic acid in patients of the acute deficiency syndrome was significantly higher than those in patients of the toxic heat syndrome, the stoppage of the qi of the bowels syndrome and blood stasis syndrome [mmol/L: 2.8 (1.5, 4.2) vs. 1.3 (1.0, 1.8), 1.6 (1.3, 3.8), 1.6 (1.2, 2.9), P < 0.001], and in septic shock group was significantly higher than that in the sepsis group [mmol/L: 4.0 (2.7, 5.7) vs. 1.4 (1.1, 1.9), P = 0.000]. The rate of qSOFA ≥ 2 score was 25.5% (28/110) in sepsis group, and 80.0% (20/25) in sepsis shock group, the difference being statistically significant (P < 0.001); while the rate of qSOFA ≥ 2 score was 69.4% (25/36) in patients of acute deficiency syndrome, 42.1% (8/19) in patients of the stoppage of the qi of the bowels syndrome, 19.1% (13/68) in patients of toxic heat syndrome and 16.7% (2/12) in patients of blood stasis syndrome, the differences also being statistically significant (all P < 0.001). The scores of SOFA in septic shock group [7.0 (5.0, 10.0)] and acute deficiency syndrome group [6.0 (4.0, 9.0)] were significantly higher compared with those in sepsis group [3.0 (2.0, 4.0)] and other syndrome types patients [toxic heat syndrome 3.0 (2.0, 4.0), the stoppage of the qi of the bowels syndrome 4.0 (2.0, 6.0) and blood stasis syndrome 4.5 (3.0, 5.0)], the differences being statistically significant (all P < 0.001). Conclusions The distribution of TCM syndromes of sepsis is related to the severity degree of sepsis, in TCM dialectical typing of sepsis, from toxic heat syndrome developing into the stoppage of the qi of the bowels syndrome, and from blood stasis syndrome to acute deficiency syndrome, the SOFA score and lactic acid level were gradually increased as the disease condition was continuously aggravating, so the SOFA score and lactic acid could be used as the reference indicators for the severity degree of sepsis; in septic patients with different TCM syndromes, the rates of qSOFA ≥ 2 were different, and the qSOFA score combined with patient's TCM syndrome can enhance the early diagnosis of sepsis.

Objective:
To analyse the mental state of patients with allergic rhinitis (AR) in Chengdu.
Methods:
One thousand five hundred and thirty-six AR patients from Sichuan Provincial Integrated Traditional Chinese and Western Medicine Hospital, West China Hospital of Sichuan University, Affiliated Hospital of Chengdu University of Traditional Chinese Medicine, Sichuan People′s Hospital, Sichuan Second Hospital of Traditional Chinese Medicine were selected from July 2013 to January 2018. Eight hundred and twenty-seven patients were screened into study group by inclusion and exclusion standards. The symptom check list 90 (SCL-90) was used to group and score the mental state of these patients according to nine classification criteria: gender, BMI, age, marital status, monthly salary, disease duration, living environment, education level and working environment. Then, the scores were compared within groups. Inter-group comparison was made between the study group and the Chinese norm, and the positive factors for psychological disorders were extracted. Four symptoms in the study group, i.e. nasal itching, sneezing, clear discharge and nasal congestion, were scored on the visual analogue scale (VAS). SPSS 19.0 software was used to carry out statistical analysis. Partial correlation analysis was performed between the positive factors and the symptom scores by multiple regression statistical method.
Results:
The total score of SCL-90 in the study group was 2.64±0.25, which was accorded with mild to moderate mental health impairment. There were 124 (15.0%) without mental health damage, 176 (21.3%) with mild damage, 474 (57.3%) with mild to moderate damage, 41 (5.0%) with moderate to severe damage and 12 (1.4%) with severe damage. The in-group comparison showed that the top three categories of different items were the living environment, gender and working environment. The scores of somatization, obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, psychosis, other (sleep, diet) and total average score of urban residents were higher than that of country residents (3.29±0.61
