Objective:
To investigate the epidemiological characteristics of measles in Jiaxing City of Zhejiang Province in different immunization program periods, so as to provide the evidence for improving prevention and control strategies of measles.
Methods:
Data of measles cases in Jiaxing City from 2005 to 2023 was collected through the Chinese Disease Prevention and Control Information System. Population, temporal, and regional distribution of measles during the periods of pre-expanded immunization program (from 2005 to 2007), expanded immunization program (from 2008 to 2010), and enhanced immunization program (from 2011 to 2023) were descriptively analyzed.
Results:
There were 3 997 measles cases reported in Jiaxing City from 2005 to 2023, with an average annual reported incidence of 4.66/105, showing a decreasing trend (P<0.05). The average annual reported incidence of measles during the periods of pre-expanded immunization program, expanded immunization program, and enhanced immunization program were 22.88/105, 7.24/105 and 0.83/105, respectively. The incidence of measles during different stages of immunization strategies all peaked from March to May. The highest reported incidence was 5.94/105 in Pinghu City and the lowest was 3.92/105 in Tongxiang City. The districts with the highest average annual reported incidence in the periods of pre-expanded immunization program, expanded immunization program, and enhanced immunization program were Nanhu District (31.10/105), Pinghu City (11.10/105) and Jiashan County (1.55/105), respectively. There was spatial clustering of measles in Jiaxing City during the period of pre-expanded immunization program (Moran's I=0.787, P<0.05), with a high-high cluster in Nanhu District.
Conclusions
The reported incidence of measles in Jiaxing City showed a decreasing trend from 2005 to 2023. There was a spatial cluster of measles incidence during the period of pre-expanded immunization program, but no significant clusters during the periods of expanded immunization program and enhanced immunization program.

Objective To investigate the differential diagnostic values of CT bronchial sign for peripheral solitary pulmonary lesions(SPLs).Methods One hundred and eleven patients with peripheral SPLs were scanned using multi-slice helical CT(MSCT),and multiplanar reconstruction was performed to show the relationship between the lesion and bronchus,the diffefences between the benign and malignancy were compared by using chi-square test.Results Bronchial cutoff rate in malignant lesions(47/95,49.5%)was markedly hi er than that in benign lesions(10/42,23.8%.X12=7.896,P<0.05),the frequency of type Ⅰ and type Ⅱ air bronchogram presented in malignant lesions(10/11.8/9)was higher than benign lesions(1/11,1/9.X2=6.975,4.818,P<0.05),but type Ⅳ in benign lesions(12/17)was more common than that in malignant lesions(5/17.X2=7.390,P<0.05).No significant difference was found in bronchus ran at the periphery of the lesion and bronchus dragged by the lesion between benign(9/24.1/4)and malignant lesions(15/24,3/4.X2=0.641,0.062,P>0.05).The focal bronchial wall thickening in malignancy(21/22)was markedly higher than benign lesions(1/22.X2=4.185.P<0.05),whereas the extensive thickening in benign lesiom(4/7)was more common(3/7.X2=8.650,P<0.05).Conclusion CT bronchial sign is very important in the differentiation of benign and malignant pulmonary lesions.

Objective: To study the chemical constituents of the flowers of Impatiens balsamina L.. Methods: The compounds were isolated by chromatography and solvant extration and the structures were identified on the basis of spectral analysis. Results: Four compounds were isolated and identified as stigmasterol(1), kaempferol(2), Kaempferol 3 glucoside(3) and Kaempferol 3 glucosyl rhamnoside(4). Conclusions: All the compounds were isolated from the flowers which were cultured for the first time in China.

Objective:To compare the osteogenic differentiation of dental pulp stem cells(DPSCs)induced by osteopontin(OPN)and mineralizing culture medium(MCM).Methods:DPSCs were cultured with OPN(OPN group)and MCM(MCM group)respectively. The morphology of the DPSCs were observed under inverted microscope.The mineralize nodules were observed by alizarin red staining. RT-RCR was used to detect the mRNA expression of bone sialoprotein (BSP),Runt-related transcription factor 2(Runx-2),osteocal-cin(OCN)and collagen-1(Col-1).Results:Similar number of mineralized nodules was found in the 2 groups(P >0.05)after 28 day culture.The mRNA expression level of BSP gene in OPN group was higher than that in MCMgroup(0.864 ±0.112 and 0.514 ±0.068, P <0.05),while the expression level of Runx-2 gene in OPN group is lower than that in MCMgroup(0.186 ±0.017 and 0.324 ±0. 058,P <0.05).The expression level of Col-1 and OCN genes in both groups were similar(P >0.05).Conclusion:The capabilities of OPN and MCMin inducing osteogenic differentiation of DPSCs are similar.

In order to reform the medical talent evaluation system, establish evaluation systems of physician competency, and implement physician resources management systems according to work position, and the compensa-tion system which reflects the value of medical services, The basic principles and standards of different physician tiers and grades are created in Shenzhen based on literature review, expert consultation and the methods from the American Centers for Medicare and Medicaid Services ( CMS) . Some results have achieved, including medical competency as-sessment of a certain number of physicians in the pilot project ( the coincidence rate of special hospitals is higher than general hospitals, respectively 78. 9% and 44. 8% ), comprehensive personnel systems reforms in public hospi-tals, and the trial selection of medical talents. The paper also provides some implications:The cognition of all sectors of society and physician themselves should be improved, Transitional policies for position recruitment and performance pay needs further improvement. Meanwhile, the grade evaluation system of non-physicians must also be given greater attention.

Non-contact measurement is an effective method of long time measurement of human electrocardiograph (ECG) signal. Because the relative position between measuring electrode and human body is not fixed, this method could result in constant changes of ECG signal collection. It often appears ECG signal distorting and weakened in filtering. This paper, using the principal component analysis (PCA) basic theory, proposes a fast adaptive PCA denoising algorithm which can automatically adjust the parameters according to the changes of ECG signal. The experiment proved that PCA denoising could be barely impacted by signal changes and can disposably remove interference signal on the premise of keeping the main features of ECG signal and can prevent ECG signal from being weakened in filtering at the same time.
