Indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO) catalyze the initial and rate limiting step in the catabolism of tryptophan, which is related to tumor immune tolerance and poor prognosis in patients. In this regard, two enzymes have become important therapeutic targets for tumor immunotherapy. So far, nine IDO1 inhibitors and three IDO1/TDO dual inhibitors have entered clinical trials. This review summarizes the research progress of IDO1 inhibitors, TDO inhibitors and IDO1/TDO dual inhibitors from the perspective of medicinal chemistry.

98 %).Conclusions Saponins are the major active ingredients in Radix Polygalae.Tenuifolin as an alkaline hydrolysis product of total saponins can be used as a chemical reference substance for the quality control of Radix Polygalae.

Objective:To analyze the clinical manifestations and esophageal motility characteristics of patients with gastroesophageal reflux disease (GERD) and extra-esophageal symptoms.Methods:From January 1 to October 30, 2018, at PLA Rocket Force Characteristic Medical Center, 180 hospitalized patients diagnosed with GERD and extra-esophageal symptoms were retrospectively analyzed. The patients were divided into laryngopharyngeal symptom group (65 cases), airway symptom group (58 cases) and mixed symptom group (57 cases). General data, clinical symptoms, gastroscopic manitestations, the results of high-resolution esophageal manometry and 24-hour multichannel intraluminal impedance and pH monitoring of each group were analyzed and compared. Chi-square test and one-way analysis of variance were used for statistical analysis.Results:The patients aged <40, 40 to 60 and >60 years accounted for 12.8% (23/180), 53.3% (96/180) and 33.9% (61/180), respectively, and the difference was statistically significant ( χ2=12.030, P=0.017). There were 18.9%(34/180) of patients without typical reflux symptoms. There were statistically significant differences in the incidence of ectopic esophagogastric mucosa or Barrett esophagus under gastroscopy between laryngopharyngeal symptom group, airway symptom group and mixed symptom group (21.5%, 14/65; 5.2%, 3/58 and 8.8%, 5/57, respectively) ( χ2=8.578, P=0.014). There were no statistically significant differences in the lower esophageal sphincter pressure (LESP), upper esophageal sphincter pressure or distal contractile integral between laryngopharyngeal symptom group, airway symptom group and mixed symptom group ((8.57±0.76), (8.87±0.79), and (10.51±0.97) mmHg (1 mmHg=0.133 kPa); (44.75±2.86), (42.81±4.06), and (39.14±3.20) mmHg; (506.13±64.30), (432.59±78.10), and (682.99±82.28) mmHg·s·cm)(all P>0.05). The DeMeester score of laryngopharyngeal symptom group , mixed symptom group and airway symptom group was (14.33±2.09), (21.94±5.30) and (30.47±5.85) points, respectively, and the difference was statistically significant ( F=3.226, P=0.043). The results of multi-channel impedance monitoring showed that acid reflux and weak acid reflux were the main reflux in the patients, which accounted for 55.5% (76/137) and 34.3% (47/137), respectively. Among 87.6% (120/137) of the patients, reflux mainly occurred in the upright position while 12.4% (17/137) of the patients had reflux in the supine position. Conclusions:The extra-esophageal symptoms of GERD is associated with age. Ectopic esophagogastric mucosa or Barrett esophagus are more common in GERD patients with laryngopharyngeal symptoms. There are more acid exposure and pathologic acid reflux in GERD mainly with airway symptoms. Weak acid reflux at upright position plays an important role in the reflux mechanism of GERD with extra-esophageal symptoms.

In order to increase the yield and quality of the medicinal plant and enhance the competitive power of industry of medicinal plant in our country, this paper analyzed the status, problem and countermeasure of the tissue culture of medicinal plant on large scale. Although the biotechnology is one of the most efficient and promising means in production of medicinal plant, it still has problems such as stability of the material, safety of the transgenic medicinal plant and optimization of cultured condition. Establishing perfect evaluation system according to the characteristic of the medicinal plant is the key measures to assure the sustainable development of the tissue culture of medicinal plant on large scale.

Objective To analyze the effect of both limited selective posterior rhizotomy(LSPR)and limited selective soft tissue release(LSTR)on healing motor function related to spasmo-cerebral palsy in both legs.Methods Thirty-eight cases CP with LSPR and LSTR were collected in the past 3 years;21 males,17 females;aged 3.0-8.11 years old,on the average of 5.11 years old.Perioperative motor function were evaluated according to motor function scores.Results LSPR and LSTR played a role in improving motor function obviously,and had little difference in orthomorphia after SPR for 6 months.Conclusion LSPR and LSTR may improve cramp and abnormality in both legs,and enhance motor function,so the secondary operation agony can be avoided,and the family economic burden relived.

Objective To analyze the concentration of epithelial cell derived neutrophil-activating protein 78(CXCL-5) in the sy-(novial) fluid(SF) and peripheral blood in children with rheumatoid arthritis(RA) and evaluate its clinical relevance to the disease development.Methods SF and peripheral sera were taken from 26 children with RA and 16 healthy controls,and CXCL-5 was measured by enzyme linked immunosorbent assay(ELISA).CXCL-5 in SF was also measured in RA children after receiving steroid treatment.Results The levels of CXCL-5 was significantly higher than that in the SF of RA children compared with healthy controls(P0.05).Interestingly,CXCL-5 markedly decreased in RA children after steroid treatment(P

Objective To provide scientific evidence for the identification and development of fructus psoraleae through its pharmacognostical study.Methods To identify fructus psoraleae by paraffin section and powder method,meanwhile,morphological identification and physical and chemical identification were also adopted.Results The morphological and microscopic characteristics of transverse section and powder of fructus psoraleae were described; fluorescent speckles of the same color were found in the same place of test samples and psoralen and isopsoralen reference by thin layer chromatography; results of water and ash determination all complied with Chinese pharmacopoeia specification,water and 70％ ethanol extractives were 21.93～39.68％,22.03～31.77％,respectively.Conclusion The established method was simple and practical with reliable results,and suitable for the identification of fructus psoraleae.
