Objective:To ensure that the metrology calibration in pharmaceutical enterprises is in compliance with the requirements of GMP, the key issues in the metrology calibration that is in the process of the implementation of the new project of pharmaceutical enterprises are researched on. Methods: The six key issues in the metrology calibration process are identified and are researched on. The six key issues is collection of the metrology information, completion of metrology information, determination of operating range and maximum permissible error, determination of calibration interval, classification management of measuring equipment, formulation of internal calibration procedure, and practical methods for the above issues are presented.Results: the metrology calibration process is controllable, the measurement result is accurate and reliable, and the measurement data can be traced back. Conclusion:when the implementation of pharmaceutical enterprises new projects, that the key issues of the metrology calibration process are made good use of these solutions can lay a good foundation for future work, and ensure that the metrology calibration process is in compliance with the requirements of GMP.

Nowadays more and more evidences suggest that glycemic management of the patients in intensive care units needs to be individualized.We should pay more attention to the diabetes history in these patients besides the primary diseases.A brief literature review and a commentary about this topic were presented in this article.

High salt intake over four months caused high blood viscosity as well as hypertension in rats, reflected by the obvious increases of blood viscosity, plasma viscosity and hematocrit, and the decrease of erythrocyte sedimentation rate. With some vicious circle resulted from certain blood viscous factors in circulatory (especially in microcirculatory) system the high blood viscosity might relate to chronic sodium chloride toxicity and easily induce hypertension.

Objective To evaluate the CT features of solitary inflammatory nodules of the lung. Methods CT features in twenty-three cases of solitary inflammatory nodules of the lung confirmed by operation or clinical were analyzed retrospectively. Spiral CT including plainscans and contrast enhanced scans was done in all patients. Thin-slice target scan and multiple plane reconstruction were used on the area of nodule. Different width and level of window were used to show the characteristic sign of the nodule.Results No calcification,satellite lesion,concentrated vessels and enlarged lymph nodes were found in or around all of the nodules. The size of these nodules were 10 mm?15 mm～30 mm?40 mm with round or irregular margin. Superficial lobular or spiculated margin was seen in only three nodules. Hyperemia and clouding appearance were found in 19 nodules and reflecting thickening pleura in 18 nodules. Unsteady edge enhancement were found in 18 nodules and no enhancement in 5 nodules. Effused change around the nodules could be seen perfectly when the level was about -400. MPR was the most accurate technique to show the relationship of nodule and pleura. Conclusion Solitary inflammatory nodules of the lung have obvious CT characterizes. By analyzing various CT manifestations comprehensively most nodules can be diagnosed correctly. Suitable width and level of window as well as MPR are helpful in showing the characterizes of the nodules.

Objective To analyze the characteristic of articles,authors and citations in Journal of Clincal Neurology from 2005 to 2007. Methods The data about articles,authors and citations in Journal of Clincal Neurology from 2005 to 2007 were analysed by bibliometrics method.Results There were 674 papers published in Journal of Clincal Neurology during the 3 years. The average number of articles per isseu was 37.4. The average number of article per paper was 0.47.The papers with funded projects were 142( 21.1%).The authors distributed in 28 mainland provinces,municipality cities and autonomous region. And main of them came from Jiangsu,Shandong,Shanghai and Beijing,and 93.1% of them shared with co-author. The coporation rate was 4.1. The ratio of the papers with citation was 86.6%,and 97% of all the citations came from journals. The average number of citation per paper were 8.6 items. The Price's indicator was 43.7%. Conclusion Journal of Clincal Neurology is an academic journal of higher quality,with stronger influence in field of clincal neurology.

Based on the hospital information system, the hospital value-added service platform is constructed.The paper intro-duces the design scheme of the platform, its functional modules, the design of the database, the implementation of the platform and its application prospect, points out that the platform can not only serve as the channel for the information exchange between doctors and pa-tients but also offer such value-added services as health consultation and illness tracking other than regular services.

Megaureter was put forward firstly by Caulk in 1923.The common causes of children obstructive megeureter have been divided into congenital(congenital ureteral stricture,congenital lower segment ureteral valve,no performance of ureteral distal and ectopic ureter openings),and secondary (urethral valve disease,ureter cyst and polyp,neurogenic bladder and iatrogenic traumatic).Now commonly used surgical treatments has approved by bladder ureter bladder reimplantation,the bladder ureter bladder reimplantation,bladder disc ureteral reimplantation,etc.This paper summarizes the research progress of obstructive megaureter.

Objective To explore the incidence of nosocomial pulmonary infection in elderly patients with cerebral infarction and its prognosis.Methods Six hundred and sixty-nine patients with cerebral infarction were divided into elderly group (384 cases,≥75 years) and control group (285 cases,40-74 years).Logistic regression analysis was used to research the risk factors for pulmonary infection.According to in-hospital heart disease,neurological damage and hospital death,the prognosis of patients in elderly group was analyzed.Results The proportion of female patients,and patients with hypertension,atrial fibrillation and congetive heart disease in elderly group was significantly higher than that in control group,the incidence of patients with nosocomial pulmonary infection was significantly higher than that in control group,the proportion of patients with smoking and diabetes was lower than that in control group,there were significant differences (P ＜ 0.05 or ＜ 0.01).The proportion of patients with high cholesterol,ischemic heart disease,peripheral arterial disease between 2 groups had no significant difference (P ＞ 0.05).Logistic regression analysis showed that diabetes and smoking were independent risk factors for nosocomial pulmonary infection (P ＜ 0.05).The proportion of patients with the United States National Institutes of Health Stroke Scale(NIHSS) score 11-15 scores in elderly group was higher than that in control group[33.59％(129/384) vs.25.96％(74/285)],there was significant difference (P ＜ 0.05),but the proportion of patients with other NIHSS score had no significant difference (P ＞ 0.05).The proportion of patients with cardioembolism in elderly group was higher than that in control group (x2 =4.38,P ＜ 0.05),the proportion of patients with large artery atherosclerosis was lower than that in control group (x2 =4.57,P ＜ 0.05).The complication rate of in-hospital heart disease,the proportion of patients with severe nerve dysfunction (modified Rankin score ≥ 2 scores) and hospital mortality in elderly group was significantly higher than that in control group,there was significant difference (P ＜ 0.01).Conclusions Nosocomial pulmonary infection is more common in elderly patients with cerebral infarction,and prognosis may be even worse.Prevention and control of pulmonary infection is very important for elderly patients with cerebral infarction.

OBJECTIVE:To establish an LC-MS method for the determination of nimesulide in human plasma. METHODS:The separation was performed on Agilent Zorbox SB-Cl8 column,using acetonitrile-0.1% formic acid (65 ∶ 35) as the mobile phase at a flow rate of 1.0 mL?min-1. The column temperature was set at 35 ℃ and valsartan was served as internal standard. Positive electrospray ionization detection was applied to monitor m/z 309(nimesulide,[M+H]+)and m/z 436(valsartan,[M+H]+). RESULTS:The linear range of nimesulide was 5～50 ng?mL-1(r=0.998 9). The method recovery of nimesulide ranged from 87.1% to 92.9%. The intra-day and inter-day RSD were 3.1%～5.8%,6.4%～9.2%,respectively.CONCLUSION:The method is sensitive,simple,convenient,accurate and reproducible,and it is suitable for clinical plasma concentration monitoring and pharmacokinetics research of nimesulide.
