Drug testing involves many analytical instruments and test items, sample pretreatment is tedious, the industry's intelligence level remains low, making drug testing a labour-intensive job. However, in the era of Industry 4.0 intelligent manufacturing, intelligent transformation of the quality control (QC) laboratory has become the focus of industry. At the same time, driven by consistency evaluation of the quality and efficacy of generic drugs and the centralized procurement policies, pharmaceutical companies have intensified their competition, further stimulating the intrinsic demand for laboratory intelligence. Based on the current state and future trends of the pharmaceutical industry, this review discusses the development of a digital and automated QC laboratory. It points out the necessity of transitioning from the traditional centralized laboratory model to an intelligent, distributed quality control model to accommodate continuous manufacturing processes. At the same time, it also analyses the potential challenges in the implementation process and coping strategies, in order to provide relevant practitioners with ideas for building intelligent QC laboratories.

Objective To evaluate the performance of bone suppression images on the detection of lung nodules in comparison with the radiologists'reading results.Methods There were 141 standard posteroanterior digital chest radiographs,which included 95 patients with a solitary nodule and 46 controls.In this observational study,4 observers,including 2 radiologists and 2 residents,in-dicated their confidence level regarding the presence of a nodule for each lung,first by use of standard images,then with the addition of bone suppression images.Receiver operating characteristic (ROC)curve analysis was used to evaluate the observers'performance. Results Average nodule size was (1.9±1)cm (range from 0.9 cm to 2.9 cm).The mean value of the area under the ROC curve (AUC)was significantly improved from 0.844 with use of standard images alone to 0.873 with use of bone suppression images (P<0.01).Conclusion The use of bone suppression images can improve radiologists'performance on detection of lung nodules on chest radiographs.

Objective To evaluate the effect of CT temporal subtraction(TS) for detection of lung nodules.Methods 80 cases of CT images (current and previous CT images) and corresponding CT TS images were presented, which included 30 cases with nodules(75 nodules) and 50 controls.4 observers, including 2 radiologists and 2 residents, indicated their confidence level regarding the presence of a new emerging or larger or solid component than before,which first used standard CT images, then with the addition of CT TS images.Receiver operating characteristic(ROC) curve analysis was used to evaluate the observers'' performance.Results The mean value of the area under the ROC curve (AUC) were 0.860 and 0.925 for four observers without and with TS images,respectively(P<0.01).Average sensitivity for detection of lung nodules was improved from 77.3%(58/75) to 89.3%(67/75) by using CT TS images.Conclusion The use of CT TS images can significantly improve radiologists'' performance for detection of lung nodules,especially when a small size solid or subsolid nodule presents near the pulmonary hilum.CT TS is more helpful for residents.

Objective To analyze the equity of health human resource allocation in public hospitals of Zhaotong city during 2008-2012,and to provide theoretical basis for the reasonable allocation of health resources.Methods The statistical description was used to analyze the number of the medical health resource,and Gini coefficient and Theli index were used to analyze the equity of health resource allocation in public hospitals of Zhaotong city.Results The amount of medical health resource showed an increasing tendency with low speed,and gaps among different areas were still existed.From 2008 to 2012,Gini coefficients of three medical health resources including the doctors,nurses and health technicians were all under 0.3.And the fluctuant tendency of the Theli Indexes and Gini coefficients were accordant with no significant increase or decrease as a whole.The combination of differences within region and difference between regions leaded to the inequity of health human resource allocation in Zhao tong city,and within region in the contribution rate of the total Theil index was greater than the difference between regions.Conclusions The quantity of health human resource is not enough in Zhaotong.The equity fluctuation of three health resources has no significatnt change.The differences within region mainly cause the inequity of health resource allocation in public hospitals of Zhao tong city.

Objective To study the changes of neutrophil surface molecule CD64 and inflammatory factor levels in patients with burn infection. Methods 46 cases of patients with burn infection who were treated in the department of burn in our hospital between March 2010 and October 2015 were selected as the observation group. Meanwhile, 46 cases of healthy people who underwent physical examination in our hospital during the same period were included in the control group. The levels of neutrophil surface molecule CD64, C-reactive protein (CRP), white blood cell count (WBC) and inflammatory factor [interleukin IL-6 (IL-6), interleukin (IL-8), tumor necro-sis factor (TNF-α) in the two groups of subjects were determined by flow cytometry and were compared. Results In the observation group, the levels of CD64, CRP, WBC and inflammatory factors were significantly higher than those in the control group (P < 0.05). Conclusion The levels of CD64, CRP, WBC and inflammatory factors in patients with burn infection are significantly higher than those in healthy people , which indicates that neutrophil surface molecule CD64, inflammatory factors and burn infection are closely correlated.

Small cell lung cancer is the most common primary neuroendocrine malignancy of the lung and is characterized by high malignant degree,rapid doubling time,easy metastasis in early stage and poor prognosis.Accurate staging of small cell lung cancer can formulate personalized therapeutic plans and improve the prognosis of patients.PET/CT can obtain metabolism and anatomical images of the whole body in one scan and improve the diagnostic accuracy and integrity.PET/CT has been widely applied to clinical practice now.PET/CT will play a more and more important role in diagnosis,staging,treatment and prognosis assessment of patients with small cell lung cancer.The value of PET/CT in staging and treatment of small cell lung cancer was reviewed in this article.
