ABSTRACT

Objective:To compare the efficacy and side effects of multi-fraction stereotactic radiotherapy (SRT) and single-fraction stereotactic radiosurgery (SRS) in the treatment of brain metastases from colorectal cancer.Methods:A total of 98 patients with brain metastases from colorectal cancer searched from the database of Professional Committee of Brain Metastasis of Shanghai Anticancer Association were recruited in this study. Among them, 46 patients weretreated with SRT and 52 patients with SRS. Clinical characteristics of all patients were analyzed between two groups and the local tumor control rate, median survival time and the incidence of radiation-induced brain injury were compared between two groups.Results:The objective remission rates (ORR) in the SRT and SRS groups were 76.1% and 67.3%, respectively. The 12-month local tumor control rates were 88.3% and 83.9% between two groups, with no statistical difference ( P=0.689). The median overall survival time of all patients was 11.6 months, 10.8 months in the SRT group and 12.7 months in the SRS group. There was no statistical difference between two groups ( P=0.129). Multivariate analysis showed that the main factors leading to poor prognosis included the number of tumors of >3( P=0.026), low GPA score ( P=0.035), and lack of systematic treatment mode and bevacizumab ( P=0.001). There was no statistical difference in the incidence of acute and late radiation-induced brain injury between two groups. Conclusions:Both SRT and SRS are effective therapies for brain metastases from colorectal cancer. The synergistic application of systematic treatment mode may be one of the main reasons affecting the survival time of the patients.

ABSTRACT

【Objective】 To investigate the voluntary blood donation status across China under COVID-19 epidemic in 2020 and the corresponding countermeasures, so as to provide reference for blood center staff. 【Methods】 A questionnaire of Survey of Blood Collection and Supply under COVID-19 Epidemic in 2020 was issued by Blood Donor Mobilization Committee of Chinese Blood Transfusion Association to conduct the data survey on blood collection and supply institutions nationwide. 【Results】 The valid data of 115 cities were collected, and detailed data of whole blood and platelet collection, clinical blood consumption, and measures taken to ensure clinical blood use under COVID-19 epidemic from 2019 to 2020 were obtained. The total volume of whole blood collection in the 115 blood supply institutions in 2020 (13 262 724.36 U)decreased by 4.83% compared with the same period in 2019(13 935 131.5 U), and the total units of platelet collection(1 582 494.5 U)was basically the same as that in 2019(1 581 139.5 U). The total clinical consumption of RBCs from the 115 blood banks in 2020(14 257 441.67 U)decreased by 3.68% compared with that in 2019(1 4801 404.19 U), and the total clinical consumption of platelets(1 738 546.42 U)was basically the same as that in 2019(1 731 037.70 U). With the support of governments at all levels, blood banks have basically guaranteed the clinical blood supply under the epidemic by organizing group blood donation for emergency, making appointments for blood donation, recruiting regular blood donors by phone and text messages, strengthening media publicity and launching haemovigilance. 【Conclusion】 The government attaches great importance to blood safety in public emergencies and plays a leading role. Making appointments for blood donation, recruiting regular blood donors through telephone and text messages and strengthening media publicity play an important role in emergency blood donation. Blood banks should cooperate closely with hospitals to coordinate emergency management of clinical blood, and took various measures to broaden sources and reduce transfusions, so as to effectively guarantee clinical blood supply during the epidemic.

ABSTRACT

【Objective】 To determine the effect of storage time on the chemokine storage and chemokine scavenging function of erythrocyte atypical chemokine receptor 1(ACKR1). 【Methods】 Samples from six bags of red blood cells product, split into two gruoups(10 mL each), were stored in a refrigerator and sampled on day 5 and day 25 during storage, respectively, to measure the concentrations of CCL5, CXCL8 and CCL11 and the ACKR1 chemokine scavenging function of erythrocytes. In addition, 42 erythrocyte products(1 mL each), stored for 5 to 25 days, were sampled to measure the expression of ACKR1 and the concentrations of chemokines CCL5, CXCL8 and CCL11 on the erythrocyte membrane. 【Results】 Compared with RBCs stored for 5 days, no difference in the concentration of CCL5(467.7±250.2 pg/mL vs 586.9±209.5pg/mL, P>0.05) and CCL11(122.2±30.3pg/mL vs 125.5 ±32.7pg/mL, P>0.05)were noticed in erythrocyte lysates stored for 25 days, but the concentrations of CXCL8 decreased significantly(42.4±5.3pg/mL vs 24.3± 5.9pg/mL, P0.05). 【Conclusion】 Erythrocytes are the main places for storing ACKR1 binding chemokines. During the storage, the chemokine scavenging of erythrocyte ACKR1 and some intracellular the ACKR1 binding chemokines are reduced.

ABSTRACT

【Objective】 To establish a reasonable and effective blood screening strategy for Hepatitis C virus (HCV), so as to reduce the risk of blood transfusion transmission, ensure blood safety and improve the quality of blood screening. 【Methods】 In order to evaluate HCV screening strategies comprehensively, the unqualified blood donations due to anti-HCV alone positivity in Dalian from 2017 to 2021 was tracked, with combined detection methods of electro-chemiluminescence immunoassay (ECLIA) and HCV-RNA nucleic acid test (NAT). 【Results】 A total of 851 (0.20%) unqualified donations due to anti-HCV alone positivity were screened from 2017 to 2021, with a decreasing trend in both numbers and rate. Among them, the unqualified rate of samples with anti-HCV reactivity in both dural-ELISA-reagent and NAT decreased significantly (P<0.05). A total of 117(0.028%) samples were anti-HCV reactive in dural-ELISA-reagent but nonreactive in NAT; 664 reactive in one-ELISA-reagent, with 70(10.54%) in Reagent Ⅰ and 594(89.46%) in Reagent Ⅱ; 122 (35.88%) out of 340 donations were reactive in ECLIA. Among the 28 participants in the follow-up test, 15 still were reactive in ELISA and 2 reactive in ECLIA. 【Conclusion】 Although the unqualified rate of HCV is decreasing, serological screening of anti-HCV is still an important method for ensuring blood safety, and its complementarity with HCV-RNA NAT should be evaluated. As a new serological assay, ECLIA has high sensitivity and specificity. Miss detection may occur if only one ELISA reagent is adopted for anti-HCV detection. Appropriate ELISA and NAT system for HCV screening should be reasonably chosen, and HCV screening strategy should be developed and adjusted according to the local conditions.

ABSTRACT

Objective:To find out predictors of the testicular ischemia caused by incarcerated inguinal hernia and evaluate the ischemic injury of the testis more accurately, which can indicate testicle exploration in time or prevent unnecessary testicle exploration.Methods:Pediatric patients (median: 9 months) undergoing operation of unilateral incarcerated inguinal hernia and ipsilateral testicular exploration from 1 Jul. 2013 to 30 Jun. 2019 were retrospectively investigated. Age at surgery, incarcerate duration, degree of intestinal and testicular injury, times of manual reduction and preoperative ultrasound data were collected. Statistical analysis was performed by SAS 9.4 (Copyright ? 2016 SAS Institute Inc.Cary, NC, USA) .Results:460 patients (median: 9 months) , of which 57 (12.39%) (median: 1.4 months, interquartile range 0.8-10.7 months) had severe testicular injury, and their average incarceration time was (23.9±9.3) h. Univariate logistic regression revealed that increased times of manual reduction, ultrasound scores, incarcerate duration and degree of intestinal injury were positively correlated with the degree of testicular ischemia, while age at surgery was negatively correlated with the degree of testicular ischemia ( P<0.05) . A model for calculating the probability of severe testicular ischemia injury was established: P= through multivariate analysis with backward stepwise logistic regression and 10-fold cross-validation was used for preliminary verification of the model. Conclusion:This study provides a relative reliable model to predict the risk of irreversible testicular ischemia due to incarcerated inguinal hernia using readily available clinical characteristics in young pediatrics with testicular ischemia.

ABSTRACT

BACKGROUND@#The prevalence of obesity and overweight in childhood has increased dramatically over the past decades globally. Thus, the risk factors of overweight and obesity in children and adolescents must be studied.@*OBJECTIVES@#This study aimed to reveal the prevalence of childhood obesity and examine the relationship between socioeconomic status (SES) and z-body mass index (z-BMI) via parental obesity and dietary intake using path analysis.@*METHODS@#Stratified cluster sampling was used to select 17,007 participants aged 6-12 years on two avenues per region in urban, suburban, and rural areas. Path analysis was conducted to examine the mediators between SES and z-BMI.@*RESULTS@#The prevalence rates of overweight and obesity were 13.36% and 8.60%, respectively, and were positively correlated with the father's education level, family income, a birth weight > 3000g, a parental obesity history, vegetable intake and red meat intake (all P < 0.05). Four mediators (paternal obesity history, red meat intake, vegetable intake, and nutritional supplements) were observed, and the four path analyses were significant (all P < 0.05). The adjusted total effects on z-BMI were significant for income (β@*CONCLUSIONS@#The prevalence of overweight/obesity in children was notable, and the relationship between SES and z-BMI was mediated by paternal obesity history and dietary intake.

ABSTRACT

Objective@#To compare the clinical efficacy of stereotactic radiotherapy (SRT) and stereotactic radiosurgery (SRS) in the treatment of brain metastases from January 2006 to December 2016, lung adenocarcinoma and analyze the related factors.@*Methods@#In this multi-center retrospective analysis, clinical data of 208 patients with brain metastases from lung adenocarcinoma were retrospectively analyzed and assigned into the SRT (n=86) and SRS groups (n=122). The clinical characteristics of patients in two groups were analyzed. The local tumor control rate, median survival time and radiation brain injury were statistically compared between two groups.@*Results@#At the end of follow-up, the objective response rates (ORR) were 70.9% and 71.3% in the SRT and SRS groups (P=0.772). The local tumor control rates at 12 months were 89% and 86% in the SRT and SRS groups (P=0.383). The median overall survival time of all patients was 14.3 months, 15.6 months in the SRT group and 13.7 months in the SRS group (P=0.349). Multivariate analysis showed that large target volume (P<0.001), low GPA score (P=0.012) and no insensitive gene mutation (P<0.001) were the main factors of poor prognosis. The incidence of late radiation brain injury was 5.8% and 14.8% in two groups (P=0.043).@*Conclusions@#SRT and SRS yield similar clinical efficacy in the treatment of brain metastases from lung adenocarcinoma. SRT may have a lower incidence of late radiation brain injury than SRS.

ABSTRACT

Objectives To compare the 2006 World Health Organization (WHO) growth standards and the 2005 China national growth standards for identification of the wasting, stunting, low weight and overweight in infants. Methods Data were drawn from“Infants’feeding and growth”project. Weight-for-length, weight-for-age and length-for-age were derived in z-scores using the two growth references. Stunting was defined as having a length-for-age Z-score less than-2. Low weight was defined as having a weight-for-age Z-score less than-2. Wasting was defined as having a weight-for-length Z-score less than-2. Overweight was defined as having a weight-for-length Z-score more than+2. Results Data of a total of 3909 records from 959 health children aged from 2 to 12 months from June 2008 to May 2009 were analyzed. Of them, 53.88%(2106/3909)were from male and 46.12%(1803/3909)were from female. There was no difference in wasting rate and stunting rate between using two growth references. Fewer infants were identified as low weight by using WHO growth standard than using China growth stan-dard. The results were 0.57%at 0-3 months (0.85%vs.1.42), P>0.05, 0.72%at 4-6 months (0.39%vs. 1.11%) and 0.97%at 7-9 months (0.79% vs.1.76%), P0.05). Con-clusion Some differences were found in low weight and overweight rate by using two growth standards. Infant low weight rate was lower and overweight rate was higher by using WHO growth standard than that using China growth standard.

Objective To confirm whether community management of hypertension could improve blood pressure control in Chongqing.Methods Cluster sampling method was used to select 5283 adults from 20 community healthcare centers in Chongqing.Matched t test was used to analyze the changes of blood pressure before and after the intervention.x2 test analysis was performed to compare the rate of normal blood pressure.Results The average age of 5283 participants was (60.5 ± 11.0) years old.Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were significantly decreased after intervention (total population:t values were 16.98 and 13.80,respectively; male:t values were 12.58 and 10.66,respectively; female:t values were 11.60 and 9.10,respectively; all P < 0.05).The most significant decrease in SBP was found in 50-59 y age group (t =15.29,P <0.05),followed by 40-49 y age group (t =9.22,P <0.05).The control rate of hypertension was increased by 5.3% after 1 year's intervention (x2 =134.5,P<0.05),except for 60-69 y age group and ≥70 y age group (x2 values were 2.5 and 1.7,respectively ; both P > 0.05).Conclusion Our results show that standardized management of hypertension in communities can decrease the level of blood pressure and increase the control rate of hypertension.

ABSTRACT

Objective To explore cost of standard operation procedure of primary public healthcare services.Methods Standard operation procedure of primary public healthcare services was put forward according to national basic public healthcare service standards (2011 edition) in 2012.Random sampling method was used to choose participants from two community sanitary service centers,two township heahhcare centers and one maternity and child heahhcare hospital.Service standard operation procedure was used to measure human cost and supportive cost of public healthcare services.Results Management of 10 thousand patients who had different diseases needed various numbers of medical staff (MS),such as health profile needed 3.4 MS,hypertension management needed 10.8 MS,diabetes management needed 10.6 MS,elderly people care needed 9.2 MS,child care needed 4.6 MS,maternal care needed 24.3 MS,psychosis management needed 13.3 MS,and planned immunity for children needed 4.6 MS.Besides,the people whole covered service projects need 2.4 MS per 100 thousand people.The research showed that managing 1 sample of different kind people needed different human cost,such as health profile needed 22.67 yuan,hypertension management needed 72.69 yuan,planned immunity for children needed 30.68 yuan,diabetes management needed 71.34 yuan,old people management needed 61.50 yuan,child care needed 30.88 yuan,maternal care needed 157.15 yuan,psychosis management needed 74.25 yuan.Besides,the people whole covered service projects needed 124.9 thousand yuan per 100 thousand people.Conclusion For primary public healthcare service project,it should be critical to modify manning regulation and labor costs.

ABSTRACT

Myeloid-derived suppressor cells (MDSCs) are a group of heterogeneous and immature myeloid-derived cells,which accumulate largely in blood,lymphoid organs,spleen and tumor tissue and so on under the different pathogenic conditions such as infection,trauma,hematosepsis,especially tumor and so on.MDSCs can suppress tumor immune through many mechanisms.The number of MDSCs in periphery blood of patients is closely related with tumor stage,tumor burden,remote metastasis and prognosis.The major results are from laboratory mice.Because of the complexity of MDSCs in patients with tumor,there are many difficulties and debate on the research of them,and the researches of human MDSCs progress slowly.
