This thesis gave the theorical origins of syndrome differentiation of CHD based on damp-pathogen by LU Zhi-zheng.Six factors includ invading by damp-pathogen,internal impairment by seven emotions,improper diet and imbalance between work and rest,different constitutions,Zang-Fu organs uncoordination,incorrect treatment,etc.are the chief factors result in damp-pathogen.The relationship between damp-pathogen and phlegm,damp-pathogen and blood stasis is analysed.Four pathogenesis that cause CHD by damp-pathogen are summarized.

Objective To discuss the relationships between regular pattern changes of plasma fibrinogen (Fib),D-dimer and fibrinogen degradation products (FDP) levels and the recent dissolution of thrombus in patients with pulmonary embolism (PE) in 14 days after treatment.Methods A prospective study was conducted.PE patients admitted to Departments of Respiratory Disease in 4 hospitals from January 2015 to March 2016 were enrolled and all of them were treated with thrombolysis and/or anticoagulation after admission.The computed tomographic pulmonary angiography (CTPA) was examined pre-treatment and 14 days post-treatment in PE patients.The pulmonary artery obstruction index (PAOI) was assessed according to the Mastora scoring method to estimate the thrombus load.The plasma Fib,D-dimer and FDP levels were measured before and on 1,2,3,5,7 and 14 days after treatment,and the relationships between the change regularities of these parameters and PAOI were also analyzed.Results A total of 42 PE patients were enrolled.The curve change of coagulation-fibrinolytic system parameters in 14 days after treatment showed that the Fib level was raised to its peak on the 3rd day after treatment and then decreased (g/L:4.24 ± 1.45 vs.3.83 ± 1.56),representing that its curve change was in accordance with the quadratic model (P =0.095).After treatment,the D-dimer and FDP levels were kept declining,they were reached the valley on 14th day [D-dimer (mg/L):1.58 ± 1.38vs.8.84 ± 6.35,FDP (mg/L):4.23 ± 3.63 vs.23.41 ± 16.54],and their curve changes were in accordance with the cubic model (F was 32.190 and 34.326,respectively both P =0.000).The PAOI variation before and 14 days after treatment [(18.77 ± 14.22)%] was not correlated with Fib variation [(1.20 ± 0.93) g/L,r =-0.194,P =0.219],but was positively correlated with D-dimer variation [(7.29 ± 7.10) mg/L] and FDP variation [(19.29 ± 18.67) mg/L,r was 0.556 and 0.460,respectively;P was 0.020 and 0.002,respectively].Conclusions The D-dimer and FDP levels are kept falling in PE patients after treatment,suggesting that the pulmonary artery embolus is being dissolved.

Colorectal cancer (CRC) is highly heterogeneous, but traditional TNM staging cannot distinguish the heterogeneity of CRC well, which can no longer meet the treatment needs. Integrating the clinical features, molecular genetic changes in cancer tissue, transcriptome and proteome changes, as well as immune matrix characteristics, the consensus molecular subtype (CMS) of CRC is by far the best description of its heterogeneity. This paper first discusses the molecular genetic changes of three types of CRC cancer tissues (chromosomal instability, microsatellite instability, and CpG island methylation phenotype). Then it systematically elaborates on the clinical characteristics, treatment directions, and prognosis evaluation of CRC patients with different CMS subtypes, as well as their relationship with immunotherapy and changes in gut microbiota. With the continuous improvement of sequencing technology and the prospective precision medicine clinical trial exploration, the "multi-molecule — multi-drug" treatment model based on CMS typing will become the core of future precision medicine and personalized medicine.

【Objective】 To construct an acute toxoplasma encephalitis mouse model by observing the pathological changes in the hippocampus of mice infected with Toxoplasma gondii strain RH. 【Methods】 The quantitative RH Toxoplasma gondii (100, 500, and 1 000 trophozoites) were injected into the hippocampal CA1 region of mice by the stereotaxic surgery; the survival status of mice was observed. Giemsa staining was used to observe the changes of toxoplasma in mouse ascites and brain tissue homogenates. Nissl staining and HE staining were used to observe the pathological changes of hippocampal nerve tissue. The distribution of Toxoplasma gondii in brain tissue was observed by immunohistochemical ABC method. 【Results】 The RH Toxoplasma gondii infected mice showed obvious symptoms such as arched back, bristling hair, abdominal distension, subtle tremor and hemiplegia on the fourth day of infection. The survival of mice in 100 trophozoites group was longer, no trophozoites of Toxoplasma gondii were found in ascites, a few pseudocysts were found in brain tissue homogenates after infected for 96 hours, and more trophozoites were found after death. Nysl staining and HE staining showed more tissue necrosis foci and loss of nerve cells in CA1 area after infected 144 h. The injury aggravated with the prolongation of infection time. Toxoplasma trophozoites were found in ascites and brain homogenates of mice in 500 and 1000 trophozoites groups. Nissl staining revealed neuronal loss and massive necrosis in the hippocampus. HE staining showed necrosis and inflammatory cell infiltration. The brain tissue injury significantly aggravated compared with 100 trophozoites group. The distribution of Toxoplasma gondii in the necrotic foci was confirmed by immunohistochemistry. 【Conclusion】 The survival of 100 trophozoite mice infected with Toxoplasma gondii strain RH was longer, and the pathological changes of brain tissue gradually aggravated. The damage was relatively confined to the brain tissue, and the mice showed typical symptoms of toxoplasma encephalitis. Therefore, the mouse model of acute toxoplasma encephalitis can be constructed by localized infection of 100 toxoplasma trophozoites, which can lay a foundation for future research on the mechanism of toxoplasma injury to cranial nerves.

Objective To investigate the feasibility of magnamosis rings designed based on magnetic compression technique in esophageal anastomosis reconstruction. Methods According to the anatomical characteristics of esophagus in SD rats, the esophageal magnamosis rings were designed. SD rats were used as animal models (n=10, 5 males and 5 females) to complete the magnetic anastomosis reconstruction of the cervical esophagus using magnamosis rings, and the operation time, animal survival, postoperative complications, magnetic rings excretion time were recorded. Two weeks after operation, the rats were killed, and the esophageal anastomotic specimens were obtained. The blasting pressure of the anastomotic site was measured and the formation of the anastomotic site was observed with naked eyes. Results Esophageal magnamosis was successfully performed in 10 SD rats, and the median operation time was 11 (8-13) min. All rats survived without anastomotic leakage, anastomotic stenosis, or magnetic rings incarceration. The magnetic rings were discharged after 8 (5-10) days and the burst pressure was higher than 300 mm Hg. Visual observation showed that the anastomotic muscle healed well and the mucosa was smooth. Conclusion The magnetic compression technique can be used for anastomosis reconstruction of esophagus, which has the advantages of simple operation and reliable anastomosis effect, and has clinical application prospect.
