Objective: To investigate the impact of New Rural Cooperative Medical System (NCMS)on rural resident’s medical burden. Methods: It investigates the survey data from the China Health and Nutrition Survey and employing difference-in-difference method based on the fixed effect model. Results: NCMS increases rural resident’s actual reimbursement rate, release the high health medical expenditure, but has limit impact on medical expenditure. The low-income group has greater risk on high medical expenditure. Conclusion: It is needed to improve the level of NCMS policy implementation; strengthen the supervision of designated medical institutions and increase policy support for low-income rural residents.

Objective: To analyze the current situation and problems of primary health care personnel since the new round of China's health care reform, and to provide a reference for stabilizing the primary health care personnel. Methods: This paper uses descriptive statistical analysis to calculate Gini coefficient and Theil index in order to ana-lyze the equity in headcount, structure and distribution of primary health care personnel among all health care institu-tions nationwide. Results: Between 2008 and 2013, the number of primary health care personnel significantly in-creased and their quality was improved. Moreover, although the Gini coefficient and Theil index of primary health care personnel continuously decreased in China's eastern, central and western provinces the difference inside the east-ern China is the main factor affecting the overall difference. Conclusions:Not only the problems of insufficient num-ber and loss of personnel still coexist in the primary health care personnel in China, but also there are other issues such as the structural imbalance of professional titles is especially prominent, the urban-rural and regional gaps are still large, etc. The main reasons for these issues are related to the irrational incentive mechanism, the inefficiency of the synergistic effects of administrative staffing policy and some reform measures, etc. This paper suggests further re-forming the income distribution system and improving primary governance capability in order to strengthen the policies to synergically attract and stabilize primary healthcare personnel.

Objective To study the clinical efficacy of pegylated interferon α-2a(PEG-IFN α-2a) and ribavirin combined with self-extracting traditional Chinese medicine(TCM) in the treatment of chronic hepatitis C(CHC) of gan-shen yin-deficiency and damp-heat syndrome.Methods A total of 59 cases of CHC of gan-shen yin-deficiency and damp-heat syndrome confirmed in our hospital was randomly divided into control group(n=29) and combined group(n=30).The patients in both groups were treated with PEG-IFN α-2a injection and ribavirin,and then the self-extracting TCM was added on the patients in combined group.The differences of quantitative score,improvement of liver function,RNA negative rate of HCV,the levels of IL-21,IL-6 and TNF-α,clinical treatment of total efficiency and adverse reactions were compared between the two groups before and after treatment.Results After treatment,the quantitative scores of TCM symptoms(rib-side pain,soreness and weakness of waist and knees,abdominal distension,red tongue with yellowish fur,dizziness with heavy body,insomnia and dreaminess) in combined group were significantly lower than those in control group(P＜0.05),but the difference of quantitative scores of other TCM symptoms between the two groups was not statistically significant(P＞0.05);The levels of alanine aminotransferase(ALT),aspartate aminotransferase (AST) and total bilirubin(TBIL) in combined group were better than those in control group(P＜0.05) after 48 weeks of treatment,but the difference of the levels of albumin(ALB) and glutamyl transpeptidase(GGT) were norstatistically significant in both groups(P＞0.05);The RNA negative rate of HCV in combined group was significantly higher than that in control group after 36-week or 48-week treatment(P＜0.05),but there was no statistically significant difference between the two groups after 12-week or 24-week treatment and 24-week follow-up;The levels of TNF-α,IL-17,IL-23 in combined group were significantly lower than those in control group(P＜0.05) after 48 weeks of treatment;The total efficiency of combined group is better than that of control group (93.33％ vs.72.41％,P＜0.05).There was no significant difference in adverse reactions between the two groups(P＞0.05).Conclusion The application of PEG-IFN α-2a and ribavirin combined with the self-extracting TCM in the treatment of CHC can obviously ameliorate the clinical symptoms and liver function indexes,improve the RNA negative rate of HCV,reduce the levels of inflammatory factors,and improve the clinical efficacy.

Objective:To explore the relationship between metabolic acidosis and cardiac valve calcification in maintenance hemodialysis (MHD) patients in the Pearl River Delta Region.Methods:Patients on MHD greater than 3 months who were treated in 10 blood purification centers in the Pearl River Delta Region from July 1 to September 30, 2019 were selected for this multicenter cross-sectional study. Based on a Doppler ultrasound, MHD patients were further divided into non-valve calcification group and valve calcification group. The demographics data, frequency of dialysis, blood pressure, single pool Kt/V(spKt/V), dialysis medications and laboratory data were collected and compared. Spearman correlation analysis was used to analyze the correlation between serum carbon dioxide combining power (CO 2CP) and cardiac valve calcification. Multivariate logistic regression model was used to analyze the influencing factors of cardiac valve calcification. Results:A total of 664 MHD patients were included in this study, with age of (57.0±14.2) years old and dialysis age of 43.0 (22.3, 71.7) months, including 395 males (59.5%) and 269 females (40.5%). Among them, there were 119 patients (17.9%) with diabetes and 186 patients (28.0%) with dialysis 2 times per week. There were 329 patients (49.5%) in the valve calcification group, and 335 patients (50.5%) in the non-valve calcification group. Compared to those in non-valve calcification group, valve calcification group had longer duration of dialysis, higher proportion of patients with dialysis 2 times per week, higher levels of diastolic blood pressure, fasting blood glucose, intact parathyroid hormone and ferritin, higher proportion of patients with blood CO 2CP<19 mmol/L (median CO 2CP), higher proportion of patients on usage of calcium channel blocker, angiotensin converting enzyme inhibitor/angiotensin receptor blocker, α-receptor blocker, β-receptor blocker, calcitriol and lanthanum carbonate (all P<0.05), while the levels of spKt/V, hemoglobin, serum CO 2CP, corrected calcium, blood phosphorus, blood alkaline phosphatase, albumin, total cholesterol, triacylglycerol, low-density lipoprotein, high-density lipoprotein, transferrin saturation, and the proportion of patients on usage of sevelamer and cinacalcet were lower (all P<0.05). Spearman analysis showed significant negative correlation between serum CO 2CP and valve calcification ( rs=-0.697, P<0.001). Multivariate logistic regression analysis showed that dialysis performed twice a week ( OR=2.789, 95% CI 1.232-6.305, P=0.014), blood total cholesterol ( OR=1.449, 95% CI 1.014-2.071, P=0.042), CO 2CP<19 mmol/L ( OR=22.412, 95% CI 10.640-47.210, P<0.001) were the influencing factor of valve calcification in MHD patients. Conclusions:MHD patients with cardiac valve calcification have significant acid loading. Metabolic acidosis is an independent influencing factor for cardiac valve calcification in MHD patients.

Objective To discuss the diagnostic value of HIT-antibodies in suspected HIT patients with heart diseases.Methods A single center study.We collected 242 blood samples of suspected HIT patients whose platelet count decreased after heparin application during July 1 st ,2012 to June 30th ,2016 in Wuhan Asia Heart Hospital and detected the concentration of HIT antibodies , meanwhile the 4T′s score were calculated.Among the study objects , there are 206 patients received cardiac surgery , 28 received cardiac interventional therapy and 8 received drug therapy.And we divided them into HIT group (44, median age 57.5, 23 females ) and non-HIT group ( 198, median age 63.5, 87 females ) according to clinical diagnosis.Quantitative data was analyzed by independent t-test or Mann-Whitney U test.Qualitative data was analyzed by Fisher′s exact test.We drew ROC curve according to the statistical analysis to determine the optimal threshold value of antibodies in diagnosis of HIT andsensitivity , specificity, negative likelihood ratio, positive likelihood ratio of the HIT antibody detection .Therefore, we can assess the value of HIT antibody detection in HIT clinical diagnosis and treatment .Moreover, we used the optimal threshold value of antibodies to testify the suspected HIT patients .Results The HIT antibody concentration of HIT group (44) and non-HIT group ( 198 ) are 3.2 ( 95% CI:1.8 -5.5 ) U/ml and 0.4 ( 95% CI:0.3 -0.4 ) U/ml, respectively.The concentration of HIT group is much higher than the non-HIT group(P<0.000).When the cut-off value of HIT-Ab is set at 0.9 U/ml, sensitivity and specificity are 93.2%and 91.9%, respectively. And negative likelihood ratio and positive likelihood ratio are 0.07 and 11.53, respectively.When the cut-off value of HIT-Ab is set at 0.6 U/ml, sensitivity and specificity are 100.0%and 73.7%.HIT-Ab and 4T′s score of ROC-AUC are 0.971 and 0.745, respectively.The diagnosis value of HIT-Ab in HIT is significantly higher than the 4T′s score ( P<0.000).Conclusions HIT antibody detection is a simple and effective auxiliary diagnostic method in HIT exclusion .And HIT antibody detection is more optimal than the 4T′s score in HIT diagnosis and treatment .

OBJECTIVETo conduct with a cost analysis of the colorectal neoplasm screening program in Beijing, and provide data evidence for decision making.

METHODSBased on stratified cluster sampling method, we carried out a 2-stage colorectal neoplasm screening program within 6 districts, Dongcheng, Xicheng, Chaoyang, Haidian, Fengtai and Shijingshan, of Beijing city between October, 2012 to May. 2013. The first stage of the program was to conducting a cancer risk level evaluation for community residents who were forty years older and the second stage's task was to providing clinical exam for those high risk people who were selected from the first stage. There were about 12 953 residents were involved in this program. We calculated the main cost of the colorectal neoplasm screen program in Beijing. Then estimate the cost of detecting one Colorectal Neoplasm patient of this program and compare it with the total treatment cost for a patient.

RESULT2 487 high risk residents were selected by the first stage and 1 055 of them made appointment for the colonoscopy exam but only 375 accepted the exam, participate rate was 35.5%. 9 neoplasm cancer patients and 71 pre-cancer patient were found at the second stage, the detection rate were 69.2/100 000 and 546/100 000, respectively. The direct input for this neoplasm screening program was 227 100 CNY and the transport expense was 4 200 CNY in the calculations. The cost for detecting one cancer patient was about 19 900 CNY. Comparing with the total medical care cost of a cancer patient (1 282 800 CNY), especially for those have been diagnosed as middle to end stage cancer, the screening program (cost 842 800 CNY) might help to reduce the total health expenditure about 128 700 CNY, based on 12 953 local residents age above 40 years old.

CONCLUSIONAn colonoscopy based colorectal neoplasm screening program showed its function on medical expenditure saving and might have advantage on health social labor creating.

Objective: To analyze the clinicopathological features of type 2 diabetes mellitus complicated with colorectal cancer (DCRC). Methods: A case-control study was conducted. Inclusion criteria: (1) hospitalized patients receiving fibrocolonoscopy; (2) adenocarcinoma and mucinous adenocarcinoma diagnosed by pathology; (3) with preoperative cTNM clinical staging; (4) colorectal cancer patients undergoing surgical treatment; (5) with postoperative pTNM staging; (6) no smoking or drinking habits. Exclusion criteria: (1) familial adenomatous polyposis (FAP); (2) Lynch syndrome; (3) carcinoma of anal canal and perianal carcinoma; (4) multiple primary cancer; (5) with serious cardiocerebrovascular diseases or multiple organ failure. Clinicopathlogical data of 32 DCRC patients who were diagnosed and treated in Peking University Shougang Hospital from December 2017 to December 2018 were retrospectively collected and analyzed. Forty nondiabetic colorectal cancer (CRC) patients during the same period were selected as control group according to the sex ratio and the age difference less than 5 years. Student′s t test and χ² test were used to compare the difference between the two groups in baseline clinicopathological data, clinical test results, tumor markers and infiltration status of T cells in tumor immune microenvironment. Results: Among 32 DCRC patients, 24 were males and 8 were females with a mean age of (63.0±1.7) years; among 40 CRC patients, 30 were males and 10 were females with a mean age of (60.5±1.6) years. The duration of diabetes mellitus in DCRC patients (from the diagnosis of diabetes mellitus to the diagnosis of colorectal cancer) was (9.2±1.3) years. The body mass index (BMI) of DCRC group was significantly higher than that of CRC group [(24.8±0.6) kg/m² vs. (23.2±0.4) kg/m², t=2.372, P=0.020]. There were no significant differences in other baseline data (sex, age, primary site of tumor, R0 resection rate, pathological stage, pathological type, differentiation degree of tumor, preoperative intestinal obstruction) between the two groups (all P>0.05). Serum triglyceride level in DCRC group was higher than that in CRC group [(2.1±0.2) mmol/L vs. (1.5±0.1) mmol/L, t=3.085, P=0.003], while hemoglobin [(120.3±5.2) g/L vs. (132.7±2.8) g/L, t=-2.224, P=0.029], anti- thrombin III [(94.2±3.7)% vs. (103.5±2.4)%, t=-2.197, P=0.031], and red blood cell count [(4.2±0.1)×10¹²/L vs. (4.5±0.1)×10¹²L, t=-2.055, P=0.044] were all lower than those in CRC group. The preoperative carcinoembryonic antigen (CEA) level in DCRC group was higher than that in CRC group [(50.3±21.8) μg/L vs. (5.6±1.0) μg/L, t=2.339, P=0.022]. There were no significant differences in preoperative levels of other four tumor molecular markers (CA199, CA242, CA724 and CA125) between the two groups (all P>0.05). The expression of Foxp3 [specific markers of CD4+, CD25+ regulatory T cells (Treg)] in DCRC group was higher than that in CRC group [(82.7±6.2) cell/HPF vs. (62.6±4.9) cell/HPF, t=2.586, P=0.012]. There were no significant differences in the infiltration of CD4, CD8, PD-1 and PD-L1 positive cells between two groups (all P>0.05). Conclusions The average diabetic history of DCRC patients is nearly 10 years. They have higher BMI and serum CEA level, and more Treg cell infiltration in the tumor. Close attention should be paid to these patients in clinical practice.
