Purpose/Significance To quantitatively analyze and evaluate 26 health informatization construction policies issued at the national level,so as to provide basis for improving related policies.Method/Process Based on the policy modeling consistency(PMC)index model,a health informatization construction policy evaluation index system is constructed,which includes 9 first-level indicators and 36 second-level indicators.Appling it to the evaluation of various policy texts,and the health informatization construction policies are analyzed in a holistic and concrete way.Result/Conclusion The overall score of the health informatization construction policies is ex-cellent.2 policies are at the perfect level,80.6％of policies are at the excellent level,and there are no bad level policy texts.However,the driving force of the policy and the balance of policy recipients need to be further improved.

Cohort study is one of the important research methods in analytical epidemiology because of its clear time sequence relationship, which is better than other observational studies in demonstrating causal association. However, screening diagnosis or other methods are often used to exclude the individuals with outcome events during the enrollment process of the subjects in cohort studies. The accuracy of screening diagnosis and the effectiveness of exclusion will affect the accuracy of the baseline status assessment of the subjects included in the study, which may lead to the causal time sequence reversal of exposure-outcome in the estimation of causal effect. Landmark analysis can be used to control reverse causality by excluding subjects with potentially unknown expose-outcome timing. In this paper, we describe the basic principles and analytical steps of landmark analysis, and use data from the Chinese Longitudinal Healthy Longevity Survey to explore the relationship between physical activity and frailty, and introduce the specific application of landmark analysis for the purpose of facilitating its application and inferring causal effects more accurately in cohort studies.

Objective:To analyze the diagnosis and treatment process, treatment methods and clinical efficacy of children with refractory Tourette′s syndrome (TS), thus providing a basis for comprehensive prevention and treatment of refractory TS.Methods:A total of 90 children with refractory TS treated in the Child Mental Health Research Center of Nanjing Brain Hospital Affiliated to Nanjing Medical University from May 2012 to July 2019 were recruited.Their baseline characteristics, diagnosis of comorbidities before and after hospitalization, combined non-drug therapy during hospitalization, the drug types used before and after admission, the dosages of main anti-tic drugs used before admission and at discharge, and the treatment outcomes of comorbidities after admission were retrospectively analyzed.The Yale global tic severity scales (YGTSS) scores and the reduction rate were used to assess the severity of tic disorder and therapeutic effect, and the clinical global impression-efficacy index (CGI-EI) scores were graded for assessing the final therapeutic efficacy.Results:Among the 90 children with refractory TS, 82 children were males and 8 children were females.There was a significant difference in the YGTSS scores at admission and discharge (25.04±12.77 vs.67.64±12.46) ( t=27.55, P<0.05). The proportion of all recruited children diagnosed with comorbidities at discharge was significantly higher than that of admission (85.56% vs.47.78%, χ2=28.90, P<0.05). Combined non-drug therapies after admission mainly included psycho-education and supportive therapy (90 cases), comprehensive behavioral intervention for tics (47 cases) and relaxation therapy (19 cases). The distribution of drugs used before and after admission was the same, and there was no significant difference in the dosages of the five major anti-tic drugs before admission and at discharge (all P>0.05). There were no significant differences in YGTSS scores and reduction rate, and CGI-EI scores of children with or without comorbidities before and after admission (all P>0.05), suggesting the similar therapeutic outcomes. Conclusions:There is no difference in efficacy between outpatient treatment and anti-tic medication of children with refractory TS, and a comprehensive hospitalized intervention can significantly improve their clinical symptoms.Diagnosis and treatment of comorbidities and combined non-drug treatments like comprehensive psychological and behavioral interventions are the key events to improve the prognosis of children with refractory TS.

Objective: To understand the awareness of palliative care and its influencing factors in community residents in Hangzhou,so as to provide basis for the development of palliative care service. Methods: By convenient sampling method,the residents in the urban-rural junction of Xihu District were recruited. A self-designed questionnaire was used to investigate their awareness of palliative care. The logistic regression model was employed to analyze the influencing factors. Results : A total of 519 questionnaires were recovered,with a response rate of 97.92%. There were 227 males and 292 females,accounting for 43.74% and 56.26%,respectively. There were 43,218 and 258 residents with more,basic and little understanding about palliative care, accounting for 8.29%,42.00% and 49.71%. The residents learned about palliative care mainly through television and radio,with 245 cases accounting for 47.21%;and they thought that the main reason for low awareness of palliative care was a lack of related knowledge,with 396 cases accounting for 76.30%. The results of multivariate logistic regression analysis showed that 50-59 years old（OR = 0.467,95% CI：0.285-0.767）,primary school education and below（OR = 2.248,95%CI：1.239-4.079）and experience of caring for dying patients（OR = 1.551,95% CI：1.094-2.199）were the influencing factors for the awareness of palliative care. Conclusion The residents in Hangzhou had relatively low awareness of palliative care,which were associated with age,education level and experience of caring for dying patients.

Objective: To observe the clinical effect of traditional Chinese medicine enema combined with rhubarb acupoint in the treatment of severe acute pancreatitis(SAP) complicated with paralytic ileus. Methods: A total of 60 SAP patients complicated with paralytic ileus treated in the First People's Hospital of Huzhou from June 2015 to June 2017 were selected and randomly divided into two groups by random lottery method, with 30 cases in each group.The two groups were treated with routine anti-infection and rehydration.The control group was treated with traditional Chinese medicine enema combined with placebo, and the observation group was treated with traditional Chinese medicine enema combined with rhubarb on Shenque acupoint, and the two groups were treated for 7d.The recovery time of blood amylase, bowel sounds recovery time, first self defecation time, local complications and mortality were observed in the two groups. Results: The recovery time of blood amylase, the recovery time of intestinal sound and the time of the first defecation were (8.87±2.30)d, (2.88±1.09)d and (3.51±1.32)d, respectively, which were significantly shorter than those of the control group [(10.29±2.01)d, (3.67±1.30)d and (4.57±1.41)d], the differences were statistically significant(t=-3.601, -3.607, -4.251, all P<0.001). The incidence rate of local complications in the observation group was 6.7%(2/30), which was significantly lower than 36.7%(11/30) in the control group(χ²=16.875, P<0.001), and there was no statistically significant difference in the mortality rate between the two groups(χ²=3.333, P=0.068). Conclusion The application of Chinese medicine enema combined with the acupoint of rhubarb in the treatment of SAP patients complicated with paralytic ileus can effectively promote the recovery of intestinal peristalsis, shorten the duration of paralytic intestinal obstruction, reduce the complications and improve the clinical effect.

Objective To evaluate the effect of strengthening nutrition intervention in gravidas with gestational diabetes mellitus (GDM) with WeChat on blood glucose control and pregnant outcomes.Methods A total of 410 gravidas,diagnosed with GDM and treated in the Department of Clinical Nutrition of Shanghai General Hospital from October 2015 to April 2016,were enrolled and randomly divided into two groups (n=205).The control group received traditional nutrition clinic education only,while the intervention group was given strengthened nutrition education through WeChat in addition to traditional education.Blood glucose level and insulin dosage were followed up after one,two and four weeks of intervention.Pregnant outcomes and patient satisfaction were investigated on 42 d after delivery.T test,Chi-square test and non-parametric test were used for statistical analysis.Results (1) Two weeks after the intervention,the average 1-hour postprandial blood glucose in the intervention group was lower than in the control group [(7.46± 1.01) vs (7.68± 1.06) mmol/L,t=2.243,P=0.025].After 4 weeks,both 1-and 2-hour postprandial blood glucose levels of the intervention group were lower than those of the control group [(7.03±0.65) vs (7.33±0.63) mmol/L,t=4.629,P＜0.05;(6.00±0.65) vs (6.21 ±0.62) mmol/L,t=3.153,P＜0.05] and more gravidas achieved euglycemia [79.9％ (151/189) vs 60.8％ (113/186),x2=16.483,P＜0.001].(2) Compared with the control group,the intervention group had a higher vaginal delivery rate [38.7％ (72/186) vs 50.5％ (95/188),x2=5.288,P=0.021] and a lower rate of postpartum complications [9.1％ (17/186) vs 2.1％ (4/188),x2=7.394,P=0.007].All of the gravidas in the intervention group were satisfied with the WeChat intervention except one lost to follow up [99.5％ (203/204)].Conclusions Strengthening nutrition education through WeChat is much more effective than traditional nutritional outpatient education alone in order to achieve a better control of blood glucose and improve pregnant outcomes in GDM women.This intervention is highly acceptable to gravidas and can be further extensively applied in nutrition clinic.

Objective To explore the diagnostic value of calcification by full field digital mammography in cases without breast palpable lumps or nodules in ductal carcinoma in situ(DC1S).Methods Based on breast imaging-reporting and data system (BI-RADS)proposed by the American College of Radiology (ACR),the cases without palpable lumps or nodules,but with calcification (over Category 4a)found by full field digital mammography admitted from Oct.2014 to Oct.2016 were analyzed.They underwent excisional biopsy after three-dimensional guide wire positioning or three-dimensional vacuum rotary cutting.After being filmed again to make sure the resection was complete,the isolated specimen were sent to pathological examination.The pathology and calcification were analyzed and summarized.Results Among 126 cases,71 (56.3％)were breast adenosis,41 (32.5％) were DCIS,6(4.8％) were infiltrating ductal carcinoma (IDC),and 8 (6.3％)were other types.The detection rate of DCIS in younger group was higher.The calcifications in DCIS were mostly linear-branching,segmental calcification,and those in IDC were mostly pleomorphic,clustering or regional calcification.Conclusion Full field digital mammography has great diagnostic value for DCIS in cases with calcification but without palpable breast lumps or nodules.

Objective To analyze the related risk factors of functional intestinal obstruction in general surgical patients and to discuss the feasible nursing and prevention measures. Methods The clinical data of totally 658 patients after abdominal surgery who received open abdominal surgery in the Department of General Surgery of the First People's Hospital of Huzhou in Zhejiang Province from January 2015 to January 2017 were retrospectively analyzed. These patients were divided into the intestinal obstruction group and the non-intestinal obstruction group based on the occurrence of postoperative functional intestinal obstruction. The single factor analysis was then conducted over the age, gender, operation time, anesthesia, postoperative analgesic use (opioids and non-opioids), abdominal operation history, smoking history, alcohol drinking history, diabetes mellitus history and history of hypertension; and Logistic regression analysis was also performed on the influencing factors to determine the impact of functional intestinal obstruction in patients who received open abdominal surgery. Results Totally 47 out of the 658 patients receiving open abdominal surgery developed functional intestinal obstruction, with an incidence of 7.14%. The univariate analysis showed that there were statistically significant differences between the two groups in gender, age, operation time, postoperative analgesic use, history of abdominal surgery and history of diabetes mellitus (P<0.05). According to the multivariate Logistic regression analysis, gender, age, operation time, history of abdominal surgery and history of diabetes were the risk factors of postoperative functional intestinal obstruction (P<0.01). Conclusions The relevant risk factors for postoperative functional intestinal obstruction in general surgical patients after abdominal surgery include gender, age, operation time, history of abdominal surgery and diabetes mellitus. Corresponding nursing and prevention measures should be taken according to the relevant risk factors of patients.

Objective To explore the effects of early functional exercise on the patients with shoulder-hand syndrome after acute stroke. Methods Totally 60 patients with shoulder-hand syndrome after acute stroke who were admitted in Zhejiang Hospital between January 2015 and January 2017 were prospectively selected and randomly divided into an observation group (n=30) and a control group (n=30). Patients in the observation group performed early functional exercise, while patients in the control group received only routine nursing. The clinical effect was compared between the patients in the two groups. Results There was no statistically significant difference in the scores for the swelling of the limb, the range of movement of metacarpophalangeal joints and the simple upper limb function before the intervention (P>0.05). After two weeks and four weeks of intervention, the swelling of the limb in the patients in the observation group was lower than that of the patients in the control group (P< 0.05). After four weeks of intervention, the scores for the range of movement of metacarpophalangeal joints in the patients in the observation group were higher than those of the patients in the control group (P<0.05). There was no statistically significant difference in the scores of anxiety and depression between the patients in the two groups (P> 0.05). After four weeks of intervention, the patients in the observation group showed lower scores of anxiety and depression than the patients in the control group (P<0.05). Conclusions Early functional exercise helps to improve the function of limbs, lower the level of anxiety and depression, and improve the quality of life in patients with shoulder-hand syndrome after acute stroke.

Objective To study the changes of activities of phase Ⅰ and Ⅱ drug-metabolic enzymes in the spleen of rats with spleen-kidney yang deficiency syndrome.Methods The rat model of spleen-kidney yang deficiency syndrome was established by gastric gavage of Radix et Rhizoma Rhei decoction combined with injection of hydrocortisone for 17 continuous days.And then we detected the activities of 6 kinds of phase Ⅰ drug-metabolic enzymes of CYP2C19,CYP2D6,CYP2C9,CYP1A2,CYP2C8,CYP3A4,and 4 kinds of phase Ⅱ drugmetabolic enzymes of phenol sulfotransferase (PST),uridine diphosphate glucuronosyl transferase 1 (UGT1),glutathione transferase (GST),estrogen sulfotransferase (SULT1E1) in the spleen.Results Compared with the normal control group,the activities of PST,UGT1,GST and SULT1E1 in the model group were significantly decreased (P ＜ 0.05 or P ＜ 0.01),and the activity of CYP1A2 was significantly increased (P ＜ 0.01),while CYP2C19,CYP2D6,CYP2C8,CYP3A4,CYP2C9 enzymes showed no obvious changes(P ＞ 0.05).Conclusion The activities of splenic drug-metabolic enzymes,in particular the phase Ⅱ enzymes,are significantly varied under the state of spleen-kidney yang deficiency.
