Drug clinical trial is an important link in the chain of new drug research and development. The results of drug discovery and development directly depend on the extent of standardization of clinical trials. Therefore, improving the quality of drug clinical trials is of great importance, and drug clinical trial institutions play a crucial role in the quality management of drug clinical trials. After years of development, the overall level of drug clinical trials has advanced rapidly in China, and a large number of clinical trials of traditional Chinese medicine have also been carried out. However, there is still a big gap between our country and developed countries. Therefore, for the construction and management of Chinese drug clinical trial institutions, there is still a long way to go. This study aims to analyze the current development of drug clinical trial institutions in China and explore the existing problems from three aspects, including current situations of institutional organization and management, regional and professional distributions, and quality control. And some suggestions are put forward finally, including support of traditional Chinese medicine, introduction of drug-risk management system, and construction of information management.

Radiotherapy plays a crucial role in cervical cancer.Intensity modulated radiation therapy is widely used gradually,which allows the photon beam within each field to be modulated and therefore improves the dose distribution by maximizing target coverage and minimizing the damage to normal tissue.Concurrent radiochemotherapy plus brachytherapy are standard therapeutic methods for local advanced cervical cancer.

Adjuvant and neoadjuvant therapy are the important therapeutic methods for rectal cancer.Neoadjuvant concurrent chemoradiotherapy and postoperative adjuvant chemotherapy play a crutial role in rectal cancer treatment.New chemotherapy drugs and targeted therapy drugs could further improve the therapeutic effect of rectal cancer.

AIM: To establish the quality standard for Zhike Pingchuan Capsule (Radix Panacis Quinquefolii, Semen Pruni Armeniacae, Radix Scutellariae, Radix Glycyrrhizae, Bulbus Fritillariae Cirrhosae, etc.). METHODS: Radix Panacis Quinquefolii, Radix Glycyrrhizae, Bulbus Fritillariae Cirrhosae in Zhike Pingchuan Capsule were identified by TLC and ginsenoside Rb_1 was determined by HPLC. The analysis was carried out on C_~18 column by HPLC. The mobile phase was CH_3CN-H_2O(34∶66). The flow rate was 1.2 mL?min~-1 and the detection wavelength was at 203 nm. The column temperature was at 40.0 ℃ and sensitivity was 0.02 AUFS. RESULTS:The average recovery was 97.20% and RSD was 2.25% and the linear range of ginsenoside Rb_1 was in 0.612-~6.120 ?g. CONCLUSION:This method is simple, rapid with a good reproducibility. This method can be used for the quality control of Zhike Pingchuan Capsule.

Objective To investigate the effect of isoflurane preconditioning on the nuclear factor kappa B (NF-kB)activity of leukocytes in patients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB).Methods Twenty ASAⅡorⅢpatients of both sexes aged 20-60 yrs undergoing cardiac valve replacement under CPB were randomly divided into 2 groups(n=10 each):control group(C)and isoflurane preconditioning group(I).Anesthesia was induced with midazolam 0.08-0.12 mg?kg~(-1),fentanyl 5-10?g?kg~(-1) and vecuronium 0.1 mg?kg~(-1).The patients were mechanically ventilated(FiO_2=100%)after tracheal intubation.Anesthesia was maintained with intermittent i.v.boluses of fentanyl and midazolam in group C or with 2 MAC isoflurane and intermittent i.v.boluses of fentanyl and midazolam in group I before CPB.Systolic BP was kept between 90-120 mm Hg,diastolic BP between 50-80 mm Hg and HR between 60-90 bpm in both groups. Isoflurane was discontinued at the initiation of CPB.Arterial blood samples were taken after tracheal intubation and before inhalation of isoflurane(T_0)at 30 min(T_1),1 h(T_2)and 2 h(T_3)after aortic unclamping for determination of NF-kB activity of leukocytes using electrophoretic mobility shift assay(EMSA).The amount of fentanyl,midazolam,dopamine and sodium nitroprusside(SNP)consumed during operation and the rate of recovery of spontaneous heart beat in both groups were recorded.Results The NF-kB activity was significantly increased after aortic unclamping in C group but there was no significant difference in NF-kB activity before CPB (T_0)and after aortic unclamping(T_(1-3))in I group.The NF-kB activity was significant lower at T_(1-3) in group I than in group C.The total amount of fentanyl consumed was 40-60?g?kg~(-1) in C group and 20-30?g?kg~(-1) in group I. Significantly less amount of dopamine was used in group I than in group C.There was no significant difference in SNP consumption between the 2 groups.The rate of recovery of spontaneous heart beat was significantly higher in group I than in group C(P＜0.01).The amount of dopamine consumed was positively correlated with the highest level of NF-kB activity in both group[r=0.962 in group C;r=0.908 in group I(P＜0.01)].Conclusion Isoflurane preconditioning can attenuate the NF-kB activity of leulocytes in patients undergoing cardiac valve replacement under CPB.

Objective To investigate the effect of different doses of dexmedetomidine combined with intercostal nerve block in regional adenomammectomy.Methods 112 patients receiving regional adenomammectomy and meeting criterions were selected from Oct.2013 to Oct.2016.And they were divided into control group and low,medium,and high dose group according to table of random number,with 28 cases in each group.Patients of the control group only received intercostal nerve block.Patients of low dose group received low dose of dexmedetomidine (0.7 μg/kg load dose and 0.25μg· kg-1·h-1 maintenance doses) combined with intercostal nerve block.Patients of medium dose group received medium dose of dexmedetomidine (0.7 μg/kg load dose and 0.5 μg·kg-1·h-1 maintenance doses) combined with intercostal nerve block.Patients of high dose group received high dose of dexmedetomidine (0.7 μg/kg load dose and 1 μg· kg-1·h-1 maintenance doses) combined with intercostal nerve block.Mean arterial pressure,heart rate,VAS score and sedation score of the four groups were detected and compared at T0,T1,T2,T3 and T4.Results The mean arterial pressure and heart rate of medium and high dose group were lower than those of the control group and low dose group at T1,T2,T3 (P＜0.05).The mean arterial pressure and heart rate of high dose group were lower than those in medium dose group at T1,T2,T3 (P＜0.05).VAS score of medium and high dose group were lower than those of the control group and low dose group (P＜0.05),while the difference was not statistically significant between medium and high dose group(P＞0.05).The sedation scores of low,medium and high dose groups were higher than those of the control group at T1,T2,T3 and T4 (P＜0.05),while the sedation score of high dose group were higher than those of low and medium dose groups at T1,T2,T3 and T4 (P＜0.05).Conclusion Medium and high dose of dexmedetomidine combined intercostal nerve block can effectively relieve pain for patients undergoing regional adenomammectomy,while high dose of dexmedetomidine is likely to cause bradycardia,hypotension and excessive sedation.Appropriate dosage should be chosen in clinical practice.
