It could not guarantee the quality of medicinal materials and decoction pieces to purely make quality standard of traditional Chinese medicine and carry out quality control. For the problems existed in each process and link of traditional Chinese medicine production,control techniques and measures of guaranteeing and improving quality should be proposed,thereby forming process control system for quality of each traditional Chinese medicine. Based on systemic research on Fructus Trichosanthis which is common traditional Chinese medicine more than30 years,the concept of establishing process control system of Fructus Trichosanthis quality is proposed firstly in this paper. The research aims to find quality problems from 10 processes and links( plant variety,cultivation and propagation,field pest control,fruiting and maturity degree of fruit,storage,regulator,chemical ingredient,quality standard,limited index and circulation),and form feasible techniques and measures solving problems in each process and link,thereby systemically guaranteeing the quality of Fructus Trichosanthis medicinal material and decoction pieces. It guarantees and improves clinical efficacy of Fructus Trichosanthis in Chinese medicine,and could provide reference for establishing process control system of quality of other traditional Chinese medicines.

[Objectives] To observe the clinical efficacy,adverse reaction and survival time of temozolomide combined with whole brain radiotherapy in the treatment of lung cancer. [Methods] A total of 43 patients with lung cancer and cerebral metastases were reviewed and analyzed. Three-dimensional conformal radiotherapy(3D-CRT) technique was used to perform whole brain radiotherapy,one time a day and5 times a week. At the same time of radiotherapy,temozolomide chemotherapy was performed,150 mg/( m2·d),continuous oral administration of 5 d,every 28 days were a cycle( those patients who continue receiving temozolomide chemotherapy did not receive other related antitumor therapy,such as systemic chemotherapy and molecular targeted therapy,etc.),and drugs were administered for 4-6 cycles according to tolerance of patients. Kaplan-Meier method was used to calculate the survival rate. [Results]The objective response rate of 43 patients was79. 0%(34/43),in which CR was 6/43,PR was 28/43,and 9 cases had PD. By December 31,2016,7 patients in 43 cases died,one patient died of cerebral hernia due to intracranial lesions and 6 patients died of failure of other important organs due to metastasis. The OS and PFS of the whole group of patients in one year were 49. 1% and 56. 9% respectively. The adverse reactions were mild and the patients could tolerate such treatment. [Conclusions] Temozolomide combined with whole brain radiotherapy in the treatment of lung cancer with cerebral metastases has excellent clinical efficacy,while patients can tolerate such treatment.
