OBJECTIVE:To know the current situation of pharmaceutical industry in China and provide suggestion for its fur-ther development. MATHODS:The structure-conduct-performance model in industrial organization theory was adopted to analyze the pharmaceutical industry statistics data in China from 2004 to 2012. RESULTS&CONCLUSIONS:The characteristic of pharma-ceutical industry market structure was numerous pharmaceutical industries,but with low industry concentration;market entry barri-ers were low;the degree of product differentiation was increasing;new product output rate was basically increased year by year in recent years. The characteristic of pharmaceutical industry market conduct was weak pricing power,more than 2 400 drugs’pricing were monitored by government;the advertisement input of drugs was increased,and only 2013 ads served through the network plat-form was reached 630 million yuan;pharmaceutical industry mergers and acquisitions were active,and there were 43 public phar-maceutical industry mergers and acquisitions in 2013;R & D spending was annually increased,and the numbers of patent applica-tions and invention patents in force in 2012 were respectively 9 580 and 10 073. The characteristic of market performance was in-crease of sales profit rate year by year,reaching 11% in 2012;the output rate of new products for several years growth rate was reached 16.68% in 2011. However,there are still large gap between China and foreign pharmaceutical industry. It is suggested that the industry structure of development of pharmaceutical industry in China should be improved by strategic merger;increase R & D input;focus on building innovative research and development platform,improve collaborative innovation capability;strengthen monitoring of pharmaceutical industry,and implement standardized management.

Objective To compare the clinical efficacy between endoscopic thyroidectomy via breast approach conventional open thyroidectomy in patients with nodular goiter. Methods A series of 70 patients with unilateral nodular goiter divided into two groups, either receiving endoscopic thyroidectomy through breast approach(endoscopic group,35 cases),or conventional open thyroidectomy(open group,35 cases). The therapeutic efficacy was compared between the two groups. Results The operating time of endoscopic group was significantly longer in the endoscopic group (100.4±26.6)min than in the open group (73.5±14.5) min(t=5. 627, P=0. 000). The postoperative drainage volume in the endoscopic group (66.7±24.9) ml significantly more than that in the open group ( 13.3±6.4)ml( t = 14. 403, P = 0. 000 ). The postoperative hospital stasignificantly longer in the endoscopic group (4.3±1.1 )d than in the open group (3.6±0.9)d(t=2.886, P=0.005). And a satisfactory cosmetic result was achieved in significantly more patients in the endoscopic group(9/24 cases) than in the open group(34/51 )(x2 = 7.235, P=0.007). There was no significant difference in intraoperative loss between the endoscopic group (22.5±15.3)ml and the open group (18.3±7.5 )ml(t=1.273, P=0.207), a consumption of analgesics between the endoscopic group (9/24 eases) and the open group(21/51 cases) (X2=0.028, P=0.867), respectively. No severe complications was encountered ,such as massive hemorrhage,injuries of the recurrent or sularyngeal nerve, or parathyroidgland injury. Conclusion Both breast approach endoscopic thyroidectomy and conventional open thyroidectomy are safe and effective, former gives better cosmetic outcomes.

In this paper attempt has been made to observe the effect of Anordrin and its analogue SIPPR-113 on the morphological characters of uterine endometrium in mice implantation period and after castration. 100 mice were used in two experiments. The first experiment was performed in mice after mating, it included 5 groups as follows: control, estradial, progesterone, Anordrin and SIPPR-113 groups. The mice were treated with least doses (2-4mg/kg) which can prevent implantation on dayl-2 after mating. The animals were killed on the 5th day of pregnancy. The second, experiment contained also 5 groups: mature female mice were treated with 1/4-1/2 of above doses on the 25-26th day and were killed on the 29th day after castration. The uterine endometrium was embedded with paraffin and Epon812, histological sections and semi-thin sections (1ftm thick) and ultra-thin sections were made. They were observed under light microscope and electron microscope (Hitachi-600). Similar results were obtained in the two series of experiments. The endometrium had grown obviously and the numbers of glands and of cell's mitosis were increased, edema was indicated in stroma, as well as secretory function of glands was prevented period of implantation. Some lysosomes and lipid drops were found in the glandular cells and micro-filaments were observed in stromal cells under electron microscope. The effect of SIPPR-113 were similar to Anordrin, their anti-implantation action may be related to their estrogen and anti-progestrone action.

Methods The performance records of material media were compared after the students of nursing specialty attended lectures with CAI method or traditional teaching method. Results Comparing CAI method with traditional teaching method, there are respective advantages. CAI method and traditional teaching method can not substitute each other. Conclusions Effect of teaching with combination of CAI method and traditional teaching method has more advantage than simple CAI method.

The respiratory cilia of normal and abnormal regions in 20 patients with lung cancer or tuberculosis were observed under electron microscope.The results show that the 9?2+2 microtubules arrangement was seen in cross section of the cilium. Ultrastructure of the cilia is about the same as that of other mammalian ceils. However,a very interesting finding was that the ciliary rootlets became greatly hypertrophied.Thus,the structure was easily identified.It appeared as striated muscles. Therefore we propose a new idea that is quite different from Satir's hypothesis about the mechanism of ciliary movement.We think that ciliary rootlets may generate movement rather than fix cilia.Dynein arms and radial spoke may be involved in supporting and fixing for ciliary movement.

Objective To evaluate the value of three-dimensional surface shaded display (SSD) and volume rendering technique(VRT) in diagnosis of scapular injury. Methods Twenty patients of scapular fractures, who were 15 males and 5 males with an average age of 34 years, were examined with SIEMENS PLUS 4 helical CT. Images were reconstructed in workstation with three-dimensional SSD and VRT, and then analyzed and compared with X-ray and 2D CT images. The regions of interesting consisted of acromion, coracoid process, glenoid cavity, supraspinous fossa, scapular spine, infraspinous fossa, lateral margin, medial margin and inferior angle of scapula. All of imagings were evaluated by two experienced radiologists with double blind method. Results 2D CT findings were clinically or operatively confirmed, and also taken as an evaluative standard to analyze the diagnostic rates of the X-ray, SSD and VRT in this study. The positive rates of diagnosis in plain X-ray and SSD were 94.44% and 97.78%, and the false negative rates was 17.65% and 7.84% respectively; the false positive rate of diagnosis of plain X-ray was 0.76%; the positive rate of diagnosis of VRT was 100%. The difference between plain X-ray, 2D CT, SSD and VRT was not statistically significant for scapular fractures, but the quality of imaging to display the fracture details of 3D CT was the best, while 3D CT might obtain the most objective view of scapular fractures. Eight cases of scapular fractures were examined again post-operatively, the reconstructed images of 3D CT displayed the structure of scapular fractures clearly. VRT could show the contour of scapula and position of the internal fixation, as well as the effect of reduction after operation and the healing status of scapular fractures. Conclusion SSD and VRT of spiral CT are effective methods in diagnosing scapular injury. The images of SSD and VRT of spiral CT may provide exact guidance to preoperative protocol and internal fixation. For complicated scapular fractures, these two techniques could be regarded as imaging techniques of choice. Furthermore, VRT provides more important information to apply the internal fixation devices and assess the result of surgical reduction.

Registration of serial images plays an increasingly important role in medicine. A novel registration method used for serial images matching is proposed, which is based on the joint histogram. After thresholding the two images to be registered, the joint histogram is divided into four separate regions. Then the criterion function is defined as bin counting in a specific region of the joint histogram, which simplifies the computation of the criteria function greatly and speeds up the alignment process significantly. We choose the Powell optimization algorithm to calculate the registration parameters. The comparison of the results from both mutual information and our method shows that the new method based on segmentation and counting is a fast, simple, efficient and accurate registration method.

An examination was conducted with holographic stereopsis test instrument on the stereoscopic vision function of 341 military personnel in different services. 94.7 percent of the total examined enjoyed normal stereopsis acuity. The pilots obtained the far most satisfactory result. One hundred percent of them were up to normal standard in terms of both far and near visions and stereopsis acuity. Meanwhile, 94.6 percent of the vehicle drivers examined also had normal stereopsis acuity. This percentage was higher compared with 83.78 percent of the civilian personnel of the same occupation. The above results indicate that the stereopsis function of personnel in military services is in good condition, and such examination is very effective and necessary as part of the physical examinations in conscription to assure the standard of the service men.
