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.

Gadd45a, a p53 and BRCA1-regulated growth arrest and DNA damage gene, plays important roles in suppressing cell transformation and tumor malignancy. Gadd45a maintains the genomic stability through inhibiting the cell growth and promoting the DNA repair etc, by which it suppresses the tumor development. Additionally, Gadd45a is involved in some important signaling pathway, contributing to its function in tumor suppressing.

OBJECTIVE: To compare the therapeutic effects of red peony root decoction, a compound traditional Chinese herbal medicine, and rhubarb in treating severe acute pancreatitis (SAP). METHODS: A total of 96 consecutive patients with objectively-graded SAP were randomly divided into treatment and control groups. There were 48 cases in each group. The patients in the treatment and control groups were assigned to receive red peony root decoction and rhubarb treatment 1-2 times a day via a gastric tube respectively. Comparisons in the time needed for the disappearance of abdominal tenderness, fever and abdominal distension were made between the two groups. The total days of using antibiotics, enzyme inhibitor, protease inhibitor, and nasojejunal feeding start, nasojejunal feeding, gastrointestinal decompression, fasting diet were also compared. And comparison also included hospital stays and hospitalization costs. RESULTS: The durations of abdominal tenderness, fever and abdominal distension in the treatment group were less than those in the control group (P<0.05). Compared with the control group, the time length for antibiotics (including anti-bacteria drug and antifungal agent) use, nasojejunal feeding start, nasojejunal feeding, gastrointestinal decompression, fasting diet, hospital stays and hospitalization costs were decreased in the treatment group (P<0.05). There were no significant differences between the two groups in enzyme inhibitor and protease inhibitor requirement, mortality and adverse reactions. CONCLUSION: Red peony root decoction is more effective than rhubarb alone for SAP patients.

OBJECTIVE: To observe the therapeutic effect of Xincang Decoction on chronic airway inflammation in children with asthma in clinical investigation. METHODS: Xincang Decoction was composed of Flos Magnoliae (Xinyi) and Fructus Xanthii (Cangoerzi), the traditional Chinese herbs for expelling wind. Sixty cases of children with bronchial asthma in remission stage were randomly divided into two groups. Thirty cases in the treatment group were treated with Xincang Decoction and the others in the control group were treated with ketotifen fumarate. The therapeutic effects of the two groups were compared, and the peripheral eosinophil (EOS) count, the levels of immunoglobulin E (IgE), interleukin 4 (IL-4) and interleukin 5 (IL-5), and the pulmonary functions were observed before and three months after the treatment. RESULTS: After three months treatment, the results showed that the total response rates of the treatment and the control group were 83.3% and 80.0%, respectively, without marked difference (P>0.05). The levels of EOS and IL-5 were obviously decreased after the treatment, and the levels of EOS and IL-5 of the patients in the treatment group were lower than those in the control group (P<0.05). Meanwhile the forced expiratory volume in one second (FEV(1)) was improved after the treatment, and the FEV(1) of the patients in the treatment group was higher than that of the patients in the control group (P<0.05). CONCLUSION: Xincang Decoction can decrease the levels of EOS and IL-5 and improve the pulmonary function in treating chronic airway inflammation in children with bronchial asthma in remission stage.

Medical English is an indispensible tool subject for medical students.However,the limited in-class teaching hours fail to provide adequate opportunities for students to participate in a diversity of subject-based tasks to practice medical English.Therefore,extracurricular activities serve as a complement to in-class teaching.Moreover,the features of extracurricular activities conform to those of Content-based instruction ( CBI),a teaching mode adopted in the teaching of ESP ( English for special purposes).The specific forms of extracurricular activities can be designed based on need analysis to cultivate the students' language competence in communicating biomedicine in Medical English.

Objective To evaluate the clinical effect of arthroscopic treatment of popliteal cyst.Methods Data of 42 patients,who had undergone arthroscopic treatment for popliteal cyst from November 2005 to January 2010,were retrospectively analyzed.There were 13 males and 29 females,including 6 children,aged from 11 to 68 years (average,43.2 years).All popliteal cysts were unilateral,including 14 cases of right knee and 28 cases of left knee.Eleven patients had recurrent popliteal cyst,and all of them underwent initial open surgery,and the duration from the initial surgery to recurrence ranged from 6 to 35 months (average,18 months).According to the Rauschning and Lindgren classification,there were 3 cases of grade Ⅰ,18 cases of grade Ⅱ and 21 cases of grade Ⅲ.Based on the MRI,the long diameter of the popliteal cysts ranged from 4.2 to 7.9 cm (average,5.4 cm),the transverse diameter 2.1 to 2.5 cm (average,2.3 cm) and anteroposterior diameter 1.6 to 2.2 cm (average,2.0 cm).All popliteal cysts were at posteriomedial parts of the knees,and 11 cases of popliteal cyst communicated with the knee joint cavity.Before operation,1 to 2 ml methylene blue was injected into the cyst,which was used to determine the channel intraoperatively according to the site where methylene blue flowed out.The intraarticular diseases were thoroughly treated when the inner wall of the popliteal cyst was cleaned.Results The intraarticular diseases were found in all patients intraoperatively,including medial meniscus tear in 28 cases,lateral meniscus tear in 9 cases and lateral discoid meniscus in 4 cases.There were no blood vessel complications,nerve complications and incision complications.All patients were discharged 2 or 3 days postoperatively.All patients were followed up for 10 to 30 months (average,18 months).No recurrence of popliteal cyst occurred at final follow-up.According to the Rauschning and Lindgren classification,there were 38 cases of grade 0 and 4 cases of grade Ⅰ.Conclusion The arthroscopic treatment of popliteal cyst has several advantages,such as mini-invasion,fast recovery and low recurrence rate.
