Objective: This research is conducted to analyze the background, the main practices and the results of the synergistic service of health institutions in Changzhou city, as well as to provide references for promoting the construction of integrated medical and health service system.Methods: This paper uses qualitative interviews and questionnaires to collect information and analyzes the data based on synergetic management theory.Results:Changzhou city has tentatively achieved the synergy of its health institutions by introducing relevant policies, setting up healthcare unions at the municipal level, integrating internal resources among healthcare unions, establishing health information platform and feedback mechanism, etc.Conclusion: The regional synergistic service of health institutions can be effectively promoted by introducing policies at the municipal level, promoting the mutual sharing and communication on information, and integrating internal resources among healthcare unions.But, as there still exist problems such as the distribution of benefits is not perfect, the degree of synergy is not close, etc., thus, the government is suggested to expand the implementation scope of the close-type medical service synergy and further improve the distribution policy of benefits.

OBJECTIVE: To investigate the characteristics of syndromes of phlegm and blood stasis in patients with coronary heart disease by multiple statistical methods of matching matrix, factor analysis and clustering analysis, and to provide some references for classification and normalization of diagnosis of syndromes of phlegm and blood stasis of coronary heart disease. METHODS: The correlations among 46 kinds of symptoms in syndrome of non-phlegm and non-blood stasis, syndrome of blood stasis, syndrome of phlegm and syndrome of phlegm-blood stasis blocking in 200 patients with coronary heart disease were analyzed by matching matrix, factor analysis and clustering analysis. RESULTS: The manifestations of tongue and pulse in syndromes of phlegm and blood stasis were significantly different from those in syndrome of non-phlegm and non-blood stasis. The pathogenesis of viscera in syndromes of phlegm and blood stasis lied in the heart and kidney, and the syndrome of deficiency of heart qi was the most common one while the syndrome of deficiency of kidney qi took the secondary place. The syndrome of phlegm was often accompanied by syndrome of deficiency of spleen qi. Only 15 ones of 46 clinical symptoms showed high frequency in concomitant appearance in syndrome of blood stasis, syndrome of phlegm and syndrome of phlegm-blood stasis blocking. Apart from having the common symptoms in syndrome of deficiency in origin, the syndrome of phlegm especially showed white and greasy fur and slippery pulse as well as distention and fullness of chest and abdominal distension; the syndrome of blood stasis showed purplish tongue and ecchymosis on tongue as well as fixed pain; and the syndrome of phlegm-blood stasis blocking showed the main symptoms of both syndrome of phlegm and syndrome of blood stasis. CONCLUSION: The statistical methods of matching matrix, factor analysis and clustering analysis are convenient, and can definitely indicate the clinical characteristics and syndrome differentiation of viscera of different syndromes of phlegm and blood stasis, which are beneficial to further research of diagnosis and differentiation of such syndromes of coronary heart disease.

Based on SWOT analysis and relevant information about the premarital healthcare services through on-site survey and literature research , this paper systematically analyzed the Strengths , Weaknesses , Opportunities and Threats of “one-stop” premarital healthcare services .It also puts forward some strategic suggestions on premarital healthcare services in China including enhancing communication and cooperation between the related national minis -tries and commissions , building a government-led multi-sectoral coordination mechanism , increasing the resource in-vestment , promoting the premarital health care service and pre-pregnancy physical examination integration , and strengthening publicity and mobilization of “one stop” service for premarital healthcare service policy recommenda-tions to provide a basis for decision-making in the promotion of the policy-related works .

With the universal two-child policy implementation, the birth rate increased, posing challenges to pediatrician allocation. Based on the birth rate, we calculated pediatrician demands and gaps during the period from 2016 to 2020 by the method of health service demand. The results showed that except Beijing and Shanghai, the ped-iatrician supply and demand ratios are less than 0 . 80 and additional numbers of pediatricians ranging from 191 981 to 198 287 are needed to meet the service demands. We recommend increasing the number of pediatricians taking both national supply-demand ratios and gaps by rationally using reasonable enrolment quota and improving the treatment and other reasonable ways to increase pediatricians. In addition, we should enhance information disclosure and guid-ance, and improve the hierarchical hospital visit system to alleviate the pressure of big cities.

With the universal two-child policy implementation, the birth rate increased, posing challenges to the maternity beds resource allocation. Based on the birth rate and the method of health service demand, we calculat-ed the maternity beds demands and gaps during the period from 2016 to 2020 . Results showed that numbers between 73 478 and 99 004 of maternity beds are needed annually and mainly allocated to eastern and central areas as well. In addition, the maternity beds of different delivery institutions should be adjusted and the hierarchical diagnosis system should be improved in order to alleviate the pressure of the obstestric acceepts in big cities like Beijing and Shanghai.

Objective:To discuss the effects of premarital health care services on birth defects in order to pro-vide some references for promoting the premarital policy .Methods: The rate of premarital healthcare and the inci-dence of birth defects and other relevant data during the period from 2000 to 2014 were collected in Guangxi province using SPSS18 .0 statistical software to carry out descriptive analysis , rank correlation analysis and time series analysis of the relevant collected data .Results: With the increase in premarital healthcare rate , the incidence of birth de-fects, neural tube defects , cleft lip and fetal edema syndrome decreased .Having a premarital subsequent effect , the higher the premarital healthcare rate , the lower of the incidence of the congenital heart disease and neural tube de-fects in the next year .Conclusion:The premarital healthcare services play an important role in reduction of birth de-fects and people's health quality improvement .As a suggestion , more attention should be paid to premarital health-care services and strengthen them , intended to improve people's health and reduce birth defects incidence .

Objective: To preliminarily investigate the difference of position fixation accuracy between polyurethane styrofoam and vacuum negative pressure pad in intensity-modulated radiation therapy (IMRT) after radical mastectomy for breast cancer. Methods: Forty breast cancer patients, who received breast-conserving surgery followed by hyper-fractionated IMRT of the whole breast (42.56 Gy for 16 times) in our hospital between 2017 and 2018 were recruited and randomly divided into the polyurethane styrofoam group and vacuum negative pressure pad group. Before IMRT treatment, the anterior and lateral films of patients were taken with kilovoltage digital radiographs (KVDRs) by Varian Trilogy machine-borne OBI KV image verification system. The KVDRs images were matched with the DRR images reconstructed by the planned system to obtain the setup errors in the left and right, head and foot, and ventral and back directions between two groups. Each patient was verified for 10 times to obtain 400 sets of data. The independent sample t-test was adopted to analyze the setup errors between two groups. The external expansion value of graded setup errors from clinical target volume (CTV) and planned target volume (PTV) was calculated. Results: The setup errors in the left and right, head and foot, ventral and back directions between the styrofoam fixation and vacuum pad groups were (1.63±1.29) mm and (1.83 ±1.61) mm (P=0.18), (1.46±1.51) mm and (2.26±2.03) mm (P=0.00), and (1.30±1.35) mm and (1.91±1.67) mm (P=0.00), respectively. The external expansion values of setup errors from CTV to PTV were 2.19 mm, 2.51 mm, 1.57 mm and 2.40 mm, 3.97 mm and 2.63 mm, respectively. Conclusion Both two fixation methods meet the clinical requirements. However, the setup accuracy and reproducibility in the polyurethane styrofoam group are better than those in the vacuum negative pressure pad group.

Objective To investigate the difference of styrofoam and breast carrier in postposition fixation of intensity-modulated radiotherapy after breast conservative surgery for breast cancer patients.Methods From February 2018 to August 2018,tweenty-four patients with breast cancer in Sun Yet-Sen Memorial Hospital of Sun Yet-sen University were selected for this study,who underwent hypofactionationed radiotherapy after breast conservative surgery with total dose 42.56 Gy/16Fractions.They were randomized into styrofoam test group and breastcarrier control group.Cone beam CT as used to record the positioning error under the directions of left and right (x),head and foot (y),abdomen and back (y) within two groups at the first,third,fifth,seventh,eleventh time before irradiation.Furthermore,the PTV extension margin was calculated and the positioning time of two groups was recorded.Two sets of pendulum errors were analyzed by independent sample T-test,and the outspread value of inter-fractional set up error of the PTV was calculated.Results The errors of the test group and the control group in the direction of x,y,z were as follows:(2.36±1.89) and (2.56±2.05) mm (P=0.49),(1.76± 1.78) and (3.28±2.79) mm (P＜0.05),(1.47± 1.49) and (1.73± 1.81) mm (P=0.28).The extension values of inter-fractional set up error of CTV to PTV were 2.97,2.92,2.21 mm and 3.41,4.09,2.59 mm respectively.The time of single positioning was (3.4± 1.1) and (5.5 ± 3.1) min respectively (P=0.01).Conclusion Styrofoam has better positioning accuracy and efficiency compared with breast carrier.

Objective:To study the ability of the Retinal Health Assessment (RHA) system to obtain fundus images in patients with different types and degrees of cataracts.Methods:A cross-sectional study was performed.Forty-five eyes of 41 patients with cataract were enrolled in First People's Hospital, Shanghai Jiaotong University from December 2016 to January 2017.Lens opacity grading and RHA fundus imaging were performed after pupil dilation.Forty-five eyes were divided into 4 groups according to the degree of lens opacity: cortical cataract group 18 eyes, nucleus cataract group 21 eyes, posterior subcapsular cataract group 2 eyes, hybrid cataract group 4 eyes.Fundus images were obtained by FullSpectrum mode of RHA2020, and the clearness of fundus images was evaluated.Scores of fundus images clarity were compared between the cortical cataract group and nucleus cataract group.This study was approved by the Ethics Committee of First People's Hospital, Shanghai Jiaotong University.Written informed consent was obtained from each patient prior to any medical examination.Results:In all 45 eyes, the phacoscotasmus classification ranged from mildest (C0N2P0, 1 eye) to very serious (C2N5P2 and C4N2P4, 2 eyes). The grade Ⅳ nuclear opacity, grade Ⅲ cortical opacity, and grade Ⅲ posterior subcapsular opacity reduced the quality of RHA images significantly, especially for images with red and green light.In cortical cataract group, images showed peripapillary vessels and retinal vessels at 580 nm and 590 nm, while retinal and choroidal vessels, as well as choroidal pigmentation, were visible at 810 nm.The clarity scores at 580, 590 and 810 nm were 2.0 (1.0, 3.0), 2.0 (2.0, 3.0) and 2.0 (2.0, 3.0), which were lower than that with red and green light (620 nm + 550 nm) (3.0[2.0, 3.0]), with statistically significant differences (all at P<0.05). In nucleus cataract group, the quality of fundus images from the eyes with grade Ⅲ nucleus cataracts was good, the image quality decreased when the nucleus opacity was grade Ⅳ, retinal vessels were occasionally observed at 580 nm and 590 nm.Additionally, retinal and choroidal vessels and choroidal pigment were visible at 810 nm and 850 nm.The clarity scores at 580, 590, 810 and 850 nm were 1.0 (1.0, 3.0), 2.0 (1.0, 3.0) and 2.0 (1.0, 3.0), which were lower than that with red and green light (620 nm + 550 nm) (3.0[1.5, 3.0]), with statistically significant differences (all at P<0.05). In posterior subcapsular cataract group, the retinal vessels were visible at 580 nm, meanwhile retinal and choroidal vessels and choroidal pigment could be observed at 810 nm and 850 nm.In hybrid cataract group, running lines of retinal vessels could be seen at 850 nm, while the central reflection was absent.Focal choroidal vessels were observed. Conclusions:Except for severe cases, RHA system can produce good quality fundus images in cataract eyes at 580, 590, 810 and 850 nm, facilitating the evaluation of fundus disease before surgery and prediction of visual outcomes after surgery.
