Objective: To set a quantified diagnostic standard for large intestinal cancer of spleen qi deficiency syndrome. Methods: The spleen qi deficiency syndrome was identified by experts on the basis of clinical epidemiological investigation of 311 patients suffering from large intestinal cancer. Corresponding points were assigned to the correlative factors (traditional Chinese medicine symptoms) on the basis of symptom differences between spleen qi deficiency syndrome and non-spleen-qi-deficiency syndrome. The best threshold was determined by receiver operating characteristic curve (ROC) according to syndrome differentiation from expert team, and the quantified diagnostic standard was established. The syndrome identification from the expert team which was regarded as golden standard was tested retrospectively. Results: All the traditional Chinese medicine symptoms possibly related to spleen qi deficiency syndrome were analyzed based on the opinions of experts, and 28 symptoms were confirmed as candidate correlative factors. The occurrence of 11 symptoms between spleen qi deficiency syndrome and non-spleen-qi-deficiency syndrome showed statistical differences by means of crosstabs analysis (P<0.05). The 11 symptoms were filtered by logistic regression analysis, and tiredness, fatigue, loose stool, and poor appetite were finally determined as the symptoms relative to large intestinal cancer. These four symptoms were analyzed with conditional probability conversion and endowed with 16, 11, 4 and 8 points respectively. The diagnostic standard of spleen qi deficiency syndrome of large intestinal cancer was over 13 points. The sensitivity, specificity and accuracy of retrospective examination were all above 80%, and its positive likelihood ratio was 9.89. Conclusion: The quantified diagnostic standard for spleen qi deficiency syndrome of large intestinal cancer is in accordance with clinical characteristics of large intestine cancer and the characteristics of TCM syndrome diagnosis.

Objective To evaluate systematically whether or not the treatment of herbs invigorating spleen and removing dampness,blood stasis and toxin with chemotherapy is better than chemotherapy alone for advanced colorectal cancer.Methods The randomized controlled trails (RCT) involving combined treatment of herbs with chemotherapy,published from January 2000 to October 2015,were searched in CBM,CNKI,Wanfang Data,VIP,PubMed,Embase databases.Stata 14.0 software was used to analyze the data.Results 19 RCT containing 941 patients were included in this reta-analysis.Compared with chemotherapy alone,the combined treatment of Chinese herbal medicine and chemotherapy was obviously better in 1-year survival rate (RR =1.28,95 ％ CI 1.14-1.45),2-year survival rate (RR =1.52,95 ％ CI 1.05-2.18),3-year survival rate (RR =2.76,95 ％ CI 1.56-4.88),objective response (RR =1.11,95 ％ CI 1.04-1.19),Karnofsky score (RR =1.46,95 ％ CI 1.27-1.68) and traditional chinese medicine (TCM) symptom score (RR =1.58,95 ％ CI 1.33-1.75).The adverse effect rate was statistically reduced in the combined treatment group:leukopenia (RR =0.59,95 ％ CI 0.40-0.8),nausea and vomiting (RR =0.68,95 ％ CI 0.59-0.79),diarrhea (RR =0.67,95 ％ CI 0.53-0.85),neurotoxicity (RR =0.79,95 ％ CI 0.65-0.96).Conclusion Compared with chemotherapy alone,the treatment of herbs invigorating spleen and removing dampness,blood stasis and toxin combined with chemotherapy for advanced colorectal cancer can significantly increase survival rate and objective response rate,improve the quality of life,and meanwhile decrease the adverse effect rate.

OBJECTIVE: To work out a qualitative diagnostic criterion for basic syndromes of traditional Chinese medicine in patients with primary liver cancer. METHODS: Based on the collection and analysis of related medical literature, clinical investigation, and experts' discussion, a preliminary qualitative diagnostic criterion for basic syndromes of traditional Chinese medicine in patients with primary liver cancer was formulated. Then it was used in clinic to be verified and revised repeatedly till it was improved to be a satisfied formal criterion. RESULTS: The basic syndromes listed in the qualitative diagnostic criterion for basic syndromes in patients with primary liver cancer consisted of two parts: excessive syndromes, including the syndromes of stagnation of qi, blood stasis, excess-heat and dampness, and deficient syndromes, including the syndromes of deficiency of qi, deficiency of blood, deficiency of yin and deficiency of yang. Each of the above syndromes could be diagnosed according to specific combination of its corresponding symptoms or signs. The clinical verification results showed that the total matching ratio was 73.92% between the diagnoses made according to the criterion and the diagnoses acquired from the experts' experience. CONCLUSIONS: The qualitative diagnostic criterion for basic syndromes of traditional Chinese medicine in patients with primary liver cancer is coincident with the experts' clinical practice. However, it needs to be further studied.

Objective:To investigate the clinical and imaging characteristics of liver density changes in patients with initial-treated drug-sensitive secondary tuberculosis during standardized treatment and after withdrawal when cured.Methods:A retrospective analysis was conducted of 34 patients with initial-treated drug sensitive pulmonary tuberculosis in Beijing Chest Hospital of Capital Medical University and the First Affiliated Hospital of Xinxiang Medical University from January 2014 to April 2019. The chest computed tomography (CT) examination and sputum culture were performed before treatment. The patients received the standardized treatment and they were divided into three groups according to the course of treatment (three, nine and 12 months). Liver density and liver function were followed up during treatment (three, six, nine and 12 months) and after drug withdrawal (3, 6 and 12 months). The measurement data were analyzed by t-test. Results:The average liver density of these three groups gradually decreased during the treatment period, and gradually increased after drug withdrawal. There were five and nine cases of fatty liver occurred at three and six months of treatment in the six-month treatment group, respectively; and six, two and zero cases of fatty liver occurred at three, six, and 12 months after drug withdrawal, respectively. There were four, eight and 11 cases of fatty liver occurred at three, six, and nine months of treatment in the nine-month treatment group, respectively; and seven, two and zero cases occurred at three, six, and 12 months after drug withdrawal, respectively.There were five, 10, 14 and 14 cases of fatty liver occurred at three, six, nine and 12 months of treatment in the 12-month treatment group, respectively; and 12, 10 and five cases occurred at three, six, and 12 months after drug withdrawal, respectively. During the course of treatment, the density of livers of some cases decreased unevenly, and the density of right lobe of the liver was lower than the left lobe. The density of left lobe of the liver was (49.8±4.0) HU, (45.0±3.9) HU, (37.0±9.9) HU, (45.3±8.1) HU, (48.4±6.6) HU at the treatment of six, nine and 12 months and drug withdrawal of three and six months, and the density of right lobe of the liver was (44.0±6.1) HU, (37.2±7.7) HU, (25.5±15.8) HU, (38.5±11.7) HU, (43.8±9.9) HU, the differences were statistically significant ( t=4.611, 4.512, 2.307, 2.803 and 2.291, respectively, all P<0.05), while those were not statistically significant among three months of treatment and 12 months after drug withdrawal ( t=1.573 and 1.199, respectively, both P>0.05). There were two cases showed alanine aminotransferase (ALT) and aspartate amiotransferase (AST) accompanied elevated (ALT>2×upper limits of normal (ULN), AST<2×ULN) at three and six months of treatment, with no abnormalities detected of alkaline phosphatase (ALP) and total bilirubin (TBil). Conclusions:The liver density gradually decreases and uneven fatty liver could appear during anti-tuberculosis treatment, but it gradually returns to normal or relieves after drug withdrawal. The degree of fatty liver is not synchronized with the changes of liver function indexes (ALT, AST, ALP and TBil), which belongs to chronic reversible injury.
