BACKGROUND: This study aimed to develop a comprehensive instrument for evaluating and ranking clinical practice guidelines, named Scientific, Transparent and Applicable Rankings tool (STAR), and test its reliability, validity, and usability. METHODS: This study set up a multidisciplinary working group including guideline methodologists, statisticians, journal editors, clinicians, and other experts. Scoping review, Delphi methods, and hierarchical analysis were used to develop the STAR tool. We evaluated the instrument's intrinsic and interrater reliability, content and criterion validity, and usability. RESULTS: STAR contained 39 items grouped into 11 domains. The mean intrinsic reliability of the domains, indicated by Cronbach's α coefficient, was 0.588 (95% confidence interval [CI]: 0.414, 0.762). Interrater reliability as assessed with Cohen's kappa coefficient was 0.774 (95% CI: 0.740, 0.807) for methodological evaluators and 0.618 (95% CI: 0.587, 0.648) for clinical evaluators. The overall content validity index was 0.905. Pearson's r correlation for criterion validity was 0.885 (95% CI: 0.804, 0.932). The mean usability score of the items was 4.6 and the median time spent to evaluate each guideline was 20 min. CONCLUSION The instrument performed well in terms of reliability, validity, and efficiency, and can be used for comprehensively evaluating and ranking guidelines.

Objective Based on mosq-ovitrap monitoring method of Aedes albopictus， to determine the spatial and temporal distribution of Aedes albopictus in Songjiang District and provide scientific evidence for prevention and control of mosquito-borne diseases. Methods From May to October， 2018‒2020， density of Aedes albopictus was monitored by using the mosq-ovitrap method. Sub-districts and towns were used as the monitoring units and the difference in mosquito ovitrap index （MOI） was compared by seasons， years and habitats. Results The total number of positive mosquito ovitraps was 1049 in 2018‒2020， and the average MOI was 8.10. Four sub-districts/towns in the urban area and the northern area had the relatively high MOIs. Moreover， MOIs in residential and external environments were higher than other habitats. In addition， MOI of Aedes albopictus decreased over years from 2018 to 2020. Conclusion Aedes albopictus is widely distributed in Songjiang District. Although the number of mosquito decreased over years after the implementation of mosquito control measures， reproduction of mosquito remains excessive in some areas and seasons. It is necessary to perform targeted control measures based on comprehensive monitoring methods.

Hemostatic materials are essential for the treatment of trauma patients with massive blood loss in battlefields and disaster environments. According to the site and severity of trauma, different types of hemostatic materials need to be used to stop bleeding urgently. At present, first-aid hemostatic materials for bleeding on body surface wounds, extremities and junctions have been well applied. However, in the case of deep bleeding wounds in the thoracic and abdominal cavity and internal organs and even non-compressible hemostasis, there are still no ideal hemostatic materials in early emergency treatment. In this review, the authors elaborate the classification and mechanism of hemostatic materials and their application in trauma first aid, so as to provide references for the use of hemostatic materials in first aid.

Objective:To investigate the impact of Bayesian penalized likelihood (BPL) PET reconstruction method on the uptake of 18F-fluorodeoxyglucose (FDG) and signal to noise ratio (SNR) of lungs, liver, aorta and bones. Methods:From March 2019 to June 2019, the 18F-FDG PET/CT images of 60 patients with clinical diagnosed tumors (29 males, 31 females, age: 24-89 (60.4±15.2) years) in Yuhuangding Hospital were retrospectively analyzed. PET images were reconstructed with ordered subset expectation maximization (OSEM), time of flight (TOF)+ point spread function (PSF) and BPL (β=350) algorithms. Volumes of interest (VOIs) were delineated on the right upper lung lobe, the right liver, aortic root and lumbar vertebra. The mean standardized uptake value (SUV mean), maximum standardized uptake value (SUV max), peak of lean body standardized uptake value (SUL peak), standard deviation of standardized uptake value (SUV SD) and the SNR were measured. The percentage of SNR change (%ΔSNR) between the BPL method and non-BPL methods were calculated. The correlations between body mass index (BMI) and %ΔSNR were analyzed by Pearson correlation analysis. One-way analysis of variance and the least significant difference (LSD) t test were used to analyze the data. Results:There were no significant differences of SUV mean and SUL peak in lung, aorta, liver and lumbar vertebra among 3 methods ( F values: 0.04-1.95, all P>0.05). The SUV max in lung, aorta, liver and lumbar vertebra of BPL reconstruction (1.14±0.82, 2.13±0.37, 2.95±0.50 and 2.76±0.87) was significantly lower than those of TOF+ PSF (1.56±0.61, 2.99±0.75, 4.32±0.94 and 4.05±1.48) and OSEM (1.51±0.67, 3.00±0.70, 4.45±1.12 and 3.81±1.06) reconstructions ( F values: 20.59-52.24, all P<0.001) and SUV SD (0.13±0.07, 0.20±0.05, 0.26±0.06, 0.38±0.17) was also significantly lower than those of TOF+ PSF (0.24±0.11, 0.43±0.11, 0.58±0.15, 0.67±0.21) and OSEM (0.21±0.09, 0.42±0.10, 0.58±0.14, 0.63±0.20) reconstructions ( F values: 24.46-124.95, all P<0.001), while the SNR (4.67±1.34, 7.74±2.22, 8.17±1.77, 4.45±1.22) was significantly higher than those of TOF+ PSF (2.54±0.72, 3.55±0.82, 3.77±0.91, 2.49±0.69) and OSEM (2.65±0.64, 3.67±0.80, 3.75±0.87, 2.60±0.67) reconstructions ( F values: 83.04-247.73, all P<0.001). However, there were no significant differences between OSEM and TOF+ PSF reconstructed images in SUL peak, SUV mean, SUV SD and SNR (all P>0.05). In BPL group, SNR increased with the increase of BMI, and there were statistically differences of aortic SNR (7.07±2.21 vs 9.67±2.26) and liver SNR (7.75±1.85 vs 9.32±0.70) between BMI<25 kg/m 2 and BMI≥30 kg/m 2 ( F values: 3.46 and 4.19, both P<0.05). Positive correlations were found between %ΔSNR of lung, aorta, liver and lumbar vertebra in OSEM and TOF+ PSF and BMI ( r value: 0.042-0.354, all P<0.05). Conclusion:In background tissues, BPL algorithm has no significant impact on absolute quantification compared with OSEM and TOF + PSF reconstruction methods but it can significantly improve SNR, especially for the patients with large body weight.

Objective:To investigate the immunogenicity and safety of a boost dose of measles, mumps, and rubella combined vaccine (MMR) for children 4 to 6 years old.Methods:Children, aged 4 to 6 years old, had vaccinated with 1 dose of measles and rubella combined vaccine(MR) at the age of 8 months and 1 dose of MMR vaccine at 18-months, were recruited in Shanxi, Inner Mongolia, and Beijing, respectively. All children were assigned into 4, 5 and 6-year-old group. The children who met inclusion and exclusion criteria were vaccinated with 1 dose MMR vaccine, and were collected blood samples before vaccination and 35 to 42 d after the vaccination. During the study period, adverse events were collected at 30 min, 1 d, 2 d, 3 d, 4-12 d, and 13 to 42 days after vaccination. Serum was tested for IgG antibodies against measles, mumps and rubella. Geometric mean concentrations (GMC) of measles, mumps, and rubella antibodies were compared among groups by analysis of variance or non-parametric test. Seropositive rates and adverse event rates were compared among groups by Chi-square test or Fisher exact test.Results:A total of 500 children were included in immunogenicity analysis and 535 children were included in safety analysis. The overall adverse event rate was 20.37%, the most of severity for adverse events was mild. The rates of local and systemic adverse events were 0.37% and 20.00%, respectively. Symptoms of local adverse events were redness. The main systemic adverse events were fever, followed by cough, rash and runny nose. Received a dose of MMR vaccine for booster immunization, the seropositive rates of measles antibody, mumps antibody and rubella antibody were above 99% for all 3 age groups, and there was no significant difference between groups. There were significant differences in mumps antibody GMC among groups ( P=0.042), but no significant differences in measles and rubella antibodies GMC. Conclusion:The immunogenicity and safety of a boosted MMR vaccintion in children aged 4, 5 and 6 years were all similar good.

In recent years, the clinical experts consensuses or guidelines of ankylosing spondylitis (AS)/spondyloarthritis (SpA) have been constantly updated, but to better understand and practice, patient self-participation management is one of the key points to improve the level of diagnosis and treatment. Through questionnaire survey of these patients, we screened out the most concerned issues, and established the AS/SpA patient practice guideline working group with multidisciplinary physicians and patients. Fifteen opinions, as the AS/SpA patient practice guidelines, are proposed in accordance with the relevant principles of the "WHO guidelines development manual" , and with the international normative process.

Objective: To summarize the clinical manifestations and treatment of retinal artery occlusion and cerebral infarction caused by facial injection of hyaluronic acid. Methods: Fifteen cases (15 eyes) with vision lose caused by facial cosmetic injection of hyaluronic acid visited Xi＇an No.4 Hospital from December 2010 to January 2017. The clinical data were collected such as general medical history and treatment methods, and follow-up for 1 year. Results: All patients were female, 22-41 years old, with average age of 33. All patients were injected with hyaluronic acid. For 8 patients the fillers were injected in the forehead, 3 patients were in the glabellar region, 3 patients were in the nasolabial fold, and 1 patient was in the temporal of left eye. All patients had vision lose after injection, the visiting time was 1 to 6 hours. 13 patients were central retinal artery occlusion (CRAO). 1 patient was retinal branch artery occlusion (BRAO), 1 patient was ischemic optic neuropathy (ION), 13 patients manifested as no light perception (NLP), 1 patient was 0.6, 1 patient was CF/30 cm, and 14 patients with cerebral infarction, manifested as headache, dizziness. All patients were given emergency treatment, and 9 patients had treated with interventional thrombolysis therapy. After treatment 11 patients, visual acuity had no significant improvement, but 4 patients improved. Headache, dizziness symptoms disappeared, but cerebral infarction lesions still existed on MRI. Conclusions Human face is a rich blood supply; vision loss and cerebral infarction could occur after injection of hyaluronic acid. After urgent treatment visual acuity is not improved obviously, eventually leading to irreversible visual impairment or even loss.

Objective: To explore the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection who received entecavir alone or in combination with anluohuaxianwan for 78 weeks. Methods: Patients with chronic HBV infection were randomly treated with entecavir alone or in combination with anluohuaxian for 78 weeks. Ishak fibrosis score was used for blind interpretation of liver biopsy specimens. The improvement in liver fibrosis condition before and after the treatment was compared. Student's t test and non-parametric test (Mann-Whitney U-Test and Kruskal-Wallis test) were used to analyze the measurement data. The categorical variables were analyzed by Chi-square test method and Spearman’s rank correlation coefficient was used to test bivariate associations. Results: Liver fibrosis improvement rate after 78 weeks of treatment was 36.53% (80/219) and the progression rate was 23.29% (51/219). The improvement of liver fibrosis was associated to the degree of baseline fibrosis and treatment methods (P < 0.05). The improvement rate of hepatic fibrosis in patients treated with anluohuaxianwan combined with entecavir at baseline F < 3 (54.74%, 52/95) was significantly higher than that in patients treated only with entecavir (33.33%, 16/48), P = 0.016 and the progression rate of hepatic fibrosis (13.68%, 13/95) was lower than that in patients treated alone (18.75%, 9/48), P = 0.466. In patients with baseline F < 3, the proportion of patients with improved and stable liver fibrosis in the combined treatment group (68.1%, 32/47) was higher than that in the treatment group alone (51.7%, 15/29). Conclusion Combined anluohuaxianwan and entecavir treatment can significantly improve the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection. Furthermore, it has the tendency to improve the stability rate and reduce the rate of progression of liver fibrosis.

Objective: To confirm early (6 hours) exercise in patients with partial hepatectomy is safe and feasible. Methods: The control group included 211 patients who qualified for partial liver resection before the accelerated rehabilitation surgery (ERAS), 218 patients with partial hepatectomy who met the entry criteria after the implementation of ERAS were taken as test group, get out of bed 24 hours after routine mission in control group, activity of 6 hours after operation in ERAS group. To observe the time of getting out of bed and the incidence of postoperative complications in 2 groups. Results: Comparison with control group, early exercise time of patients in ERAS group after surgery. The incidence of postoperative complications decreased was 14.3% (31/218) while 34.6%(73/211) of the control group. The difference was statistically significant (χ²=299.3, 18.270, P < 0.01). And did not increase the risk of falls, incision pain, postoperative bleeding. Conclusion Liver partial resection is safe and effective for patients with 6 hours post-operative exercise, worth clinical application.

Objective: To evaluate the influence of happiness therapy intervention on the medication compliance and quality of life of acquired immune deficiency syndrome (AIDS) patients after discharge. Methods: A total of 106 adult AIDS patients discharged from hospital from July 2016 to July 2017 were randomly divided into control group (52 cases), observation group (54 cases). The control group was given routine health education and instruction, and three times of happiness therapy intervention were performed during the hospitalization. The observation group increased the number of happiness therapy intervention after discharge according to the patient′s medication compliance. The medication compliance scale and quality of life scale were used to evaluate the compliance rate and quality of life of patients in 2 groups at discharge, 3 months after discharge, 6 months after discharge, and 12 months after discharge. Results: There was no significant difference in medication compliance and quality of life at discharge and 3 months after discharge between the two groups (P>0.05). At 6 months and 12 months after discharge, the compliance rate and quality of life scores in the observation group was 90.74%(49/54), 88.89%(46/54) and (69.62 ± 5.82) points, (68.76 ± 5.63) points, respectively, 61.54% (32/52), 59.62% (31/52) and (52.12 ± 4.30) points, (52.05 ± 4.25) points in the control group, the difference was statistically significant (χ²=9.684, 9.035, t=8.638, 8.963, P<0.01). Conclusions The happiness therapy intervention during hospitalization can effectively improve the medication compliance and quality of life of AIDS patients. After the discharge, the happiness therapy intervention can provide the patients with long-term nursing programs, which can improve the adherence and quality of life of AIDS patients compared with the control group Have a better long-term effect.
