OBJECTIVE:To provide reference for the sustainable development of pharmaceutical enterprises in Guizhou prov-ince. METHODS:A questionnaire was conducted for 55 pharmaceutical enterprises in Guizhou province,the basic situation of en-terprises,familiarity of related directors to Good Manufacture Practice of Drugs(GMP)and relevant policy,the current situation of implementing the new version GMP were investigated and statistically analyzed,problems were found,and corresponding coun-termeasures were put forward. RESULTS & CONCLUSIONS:Totally 55 questionnaires were sent out,49 valid ones were received with effectively recovery of 85.1%. The results showed 43 enterprises(87.8%)had passed the GMP authentication;only 13 enter-prises(26.5%)directors were very familiar with the new version GMP. In terms of personnel management,the head of production management and quality management and the authorized person of quality and personnel had not yet met related requirements of the new version GMP fully;in terms of equipment and production management,production area transformation(clean areas,lounges, warehouses,water use) and air purification system design in most enterprises met related requirements of the new version GMP, 23 enterprises (46.9%) still can not conduct fully inspection to products and materials;in terms of document management,there were still some enterprises not meeting the new version GMP standards fully,enterprises'documents(health area layout,air purifi-cation layout,management procedures,operating procedures,etc.) of production site were imperfect. According to the investiga-tion,the main existing problems included lack of funds in implementing the new version GMP reform,not enough understanding or familiarity with the new version GMP,relevant personnel management not reaching the designated position,equipment and pro-duction management needing to be strengthened,document management systemic being poor,risk management being not sound, etc. It is suggested that government should give all forms of capital policy and strengthen the training of the new version GMP;en-terprises should attach great importance to the relevant personnel management,strengthen the equipment and production manage-ment,set up perfect document management system and a sound system of risk management.

Objective To evaluate mono-and bi-exponential decay models in the diagnosis of hepatocellular carcinoma (HCC). Methods 28 patients with HCC who underwent conventional MRI imaging and diffusion-weighted imaging were collected,and all the HCC lesions were proved by operation pathology.The ADC values in mono-exponential decay model and ADCst ,ADCslow , ADCfast and ffast of the lesions in bi-exponential decay model were measured through the reconstruction of ADCmap ,ADCslow map, ADCfast map and fraction of fast ADC at a workstation.The relationships between the ADC values with low,medium and high b-val-ues and different differentiation degrees of HCC were analyzed.Moreover,the relationships between the ADCst ,ADCslow ,ADCfast , ffast values and HCC defferentiation grades were also explored.Results Significant differences in ADC value were found among differ-ent degrees of HCC differentiation in middle and high b-value groups (P <0.05).A positive correlation was found between the ADC value and the degree of HCC differentiation in middle (r=0.377,P <0.01)and high b-value group (r =0.81 5,P <0.01).There were no significant differences in ADC value among the different degrees of HCC differentiation in low b-value group.There were significant differences in the values of ADCst ,ADCslow and ADCfast among different degrees of HCC differentiation.Significant posi-tive correlations were found between the values of ADCst ,ADCslow and ADCfast and the degree of differentiation (P <0.01).There were no significant differences in the values of ffast among different degrees of HCC differentiation.Conclusion ADC value in mono-exponential decay model plays a potential role in the diagnosis of different differentiation degree of HCC with a b value ≥400 s/mm2 .Furthermore,the parameters in bi-exponential decay model,especially the values of ADCst ,ADCslow and ADCfast ,can provide new and unique information in the distinction of different degrees of HCC differentiation.

Objective To investigate the expression of signal-induced proliferation-associated gene 1 (SIPA1), Ezrin and E-cadherin (E-cad), and their relationship with clinical patterns in epithelial ovarian carcinoma.Methods Immunohistochemistry was used to detect the expression of SIPA1, Ezrin and E-cad in normal ovarian tissue, benign epithelial ovarian tumor, borderline epithelial ovarian tumor and epithelial ovarian carcinoma,respectively. Results The positive rate of SIPA1 expression was 44.2 % (23/52), 64.5 %(20/31), 93.3 % (28/30) and 100.0 % (15/15) in epithelial ovarian carcinoma, borderline epithelial ovarian tumor, benign epithelial ovarian tumor, and normal ovarian tissue, respectively, and there was a statistical difference (χ2 = 29.159, P= 0.000). The corresponding rates were 57.7 % (30/52), 61.3 % (19/31), 90.0 %(27/30) and 93.3 % (14/15) for the positive rate of Ezrin expression (χ2= 14.555, P= 0.002), as well as for 23.1 % (12/52), 58.1 % (18/31), 86.7 % (26/30) and 0 (0/15) for the positive rate of E-cad expression, respectively (χ2= 45.731, P= 0.000). In patients with epithelial ovarian carcinoma, the expression of SIPA1 was correlated with tumor differentiation (χ2=3.895, P=0.048), but not with histological type and clinical stage (all P>0.05). The expression of Ezrin was not correlated with histological type, tumor differentiation and clinical stage (all P>0.05). There was a positive correlation between expression of E-cad and SIPA1, Ezrin in epithelial ovarian carcinoma, respectively (r= 0.339, P= 0.014; r= 0.284, P= 0.041), but no correlation between the expression of SIPA1 and Ezrin (r= 0.214, P= 0.128). Conclusions SIPA1, Ezrin and E-cad play important roles in the occurrence and development of epithelial ovarian carcinoma. They cooperate in the progression and their combined detection can better evaluate the prognosis of epithelial ovarian carcinoma.
