RESUMEN
Trollius chinensis has a wide range of pharmacological effects ，including anti-oxidative ，antibacterial，antiviral， anti-inflammatory，anti-tumor，anti-aging，antipyretic and analgesic effects ，relieving cough and removing phlegm ，viscera protection，and so on. Flavonoids and phenolic acids are the main medicinal components of it ，especially three monomers have a wide range of efficacy and have been studied more ，such as orientin ，vitexin and 2″-O-galactopyranosyl orientin. T. chinensis is mostly used in clinical practice in the form of Chinese patent medicines ，such as Jinlianhua granules ，Jinlianhua capsules ， Jinlianhua tablets and Jinlianhua oral liquid. These medicines are used to treatment of upper respiratory tract infection ，pharyngitis， tonsillitis，periodontitis，mumps，oral ulcer ，and hand-foot-mouth disease. They are usually used by combining with Western medicine. Due to its definite curative effect and less adverse drug reactions ，T. chinensis related preparations are more suitable for pediatric population ，and they can be used for the treatment of upper respiratory tract infection in children ，acute suppurative tonsillitis in children ，epidemic mumps in children ，hand-foot-mouth disease in children ，which is also one of its drug characteristics. This paper review the relevant literatures in recent 20 years from the respective of pharmacological effects and clinical applicationin order to provide reference for further promoting rational clinical application of T. chinensis and new drug research and development.

Objective To study the surgical treatment and clinical effect of growth hormone type pituitary tumor complica-ting cardiomyopathy .Methods Sixty-five cases of growth hormone type pituitary adenoma complicating cardiomyopathy in the hos-pital from June 2012 to June 2016 were selected and performed transsphenoidal approach pituitary adenoma resection .Then serum growth hormone level ,ECG results ,ultrasound cardiogram results and clinical symptoms were observed at 2 weeks after operation . Results The signs were significantly improved after surgery ,acromegaly and nasolabial hypertrophy were significantly improved , dizziness ,fatigue ,hypertension and hyperglycemia were significantly improved ;the average postoperative growth hormone level was (4 .37 ± 2 .03)μg/L ,which was significantly lower than (40 .27 ± 4 .18)μg/L before operation ,and the difference was statistically significant (P< 0 .01 );postoperative IVST ,LVIDd and LVPWT were significantly lower than those before operation ,and the difference was statistically significant (P<0 .01);postoperative average E/A and LVEF were significantly lower than those before operation ,and the difference was statistically significant (P<0 .01) .Conclusion Transsphenoidal pituitary tumor resection can re-duce the level of grow th hormone and improves the cardiac function .
RESUMEN
Hepatic ischemia-reperfusion injury (HIRI) is a process caused by the combined effect of various factors, and to some extent, it limits the development of liver surgery. In-depth studies on mechanisms of HIRI and the development of reasonable therapeutic strategies have positive effects on the prognosis of patients. This article introduces the pathogenesis of HIRI, including calcium overload, Kupffer cells, microcirculation disturbance, production of reactive oxygen species, complement, non-coding RNA, and various cytokines, and the combined effect of these factors induces the necrosis and apoptosis of hepatocytes. In addition, as a second mode of cell death, autophagy is also involved in HIRI. Due to the complex mechanism of HIRI and many factors involved, intervention should be given from various aspects. This article points out that with the development of intervention such as ischemic pretreatment, mild hypothermia and hydrogen, the new therapeutic methods are expected to bring new thoughts to the clinical intervention of HIRI.
RESUMEN
Objective:To investigate the effect of gemcitabine on myeloid derived suppressor cells (MDSC) in the spleen of B lymphoma cell-bearing mice, and the therapeutic effect of gemcitabine combined with intratumoral injection of dendritic cells (DCs) in treatment of large B lymphoma. Methods: BALB/c mice were inoculated subcutaneously with B lymphoma A20 cells; large tumors were formed 30 d after inoculation. Gr-1~+ CD11b~+ MDSC proportion in the spleen was analyzed by flow cytometry before and after gemcitabine treatment. Splenic MDSC sorted by immunomagnetic beads was further treated with gemcitabine, and then the apoptosis of MDSC was examined by Annexin-V/PI staining. Tumor growth and survival time of A20 tumor-bearing mice were observed after treatment with gemcitabine and intratumoral injection of DCs. Results: Splenic Gr-1~+ CD11b~+ MDSC ratio in A20 cell-bearing mice was 10 times higher than that in the normal mice. Gemcitabine induced apoptosis and necrosis of purified MDSC in vitro in a time-dependent manner. The percentage of MDSC in the spleen of A20 tumor-bearing mice was decreased after injection of a single dose of gemcitabine. Gemcit-abine or intratumoral injection of DCs alone inhibited growth of tumor to a certain degree, with the mean survival periods of mice in the gemcitabine, DCs, and untreated groups being (48.8±3.6) d, (47.2±7.4) d, and (38.8±2.2) d, respectively. Gemcitabine chemotherapy combined with intratumoral DC injection resulted in continuous shrink of the tumors, and 60% of the mice survived for more than 90 d. Conclusion: Gemcitabine can effectively eliminate splenic MDSC in tumor-bearing mice. Gemcitabine chemotherapy and DCs immunotherapy can work synergistically in the treat-ment of huge lymphoma. These results provide an experimental basis for the comprehensive chemotherapy and immunotber-apy of relapsed or refractory lymphoma.
