Objective To explore the correlation between intestinal dose and acute radiation enteritis(ARE)in patients with cervical cancer received concurrent chemoradiotherapy,and optimize the dose limit of intestinal tissue.Methods 158 cervical cancer patients received concurrent chemoradiotherapy from 2014 to 2019 were selected in this study.According to CTCAE 5.0,patients with ARE≥grade 2 were classified as ARE≥grade 2 group,otherwise classified as ARE0.7,P<0.05).Conclusions For patients with cervical cancer received concurrent chemoradiotherapy,the dose of bowelbag V5 and V40 should be considered to rationally optimize the dose of bowelbag in the radiotherapy plan,so as to reduce the incidence of ARE≥grade 2.

Objective: To evaluate the diagnostic value and application of 24 h multichannel intraluminal impedance-pH (24 h MII-pH) monitoring in children with gastroesophageal reflux disease (GERD). Methods: This is a cross-sectional study. From January 2013 to December, 2020, 417 patients who received 24 h MII-pH monitoring in Department of Gastroenterology of Children's Hospital Capital Institute of Pediatrics were included. According to results, these children were divided into the GERD and non-GERD groups. Furthermore, the 132 children with GERD who had gastroscopy were divided into the reflux esophagitis (RE) and non-erosive reflux disease (NE) groups to investigate the differences in their refluxes. Non-parametric Mann-Whitney U test or indepentent sample t test was used for comparisons between the groups. Results: Among the 417 children, 232 were males and 185 females, aged (7.3±3.9) years. The course of disease was 0.5 (0.1, 2.0) years. The main clinical symptoms included acid reflux (128 cases), vomiting (173 cases), abdominal pain (101 cases), and cough (76 cases). The 24 h MII-pH monitoring were positive in 243 children (58.3%, 243/417), which was higher than that by 24 h esophageal pH monitoring (43.6%, 182/417). The 24 h MII-pH monitoring results demonstrated significant differences in the episodes of acid reflux, weakly acidic reflux, non-acidic reflux, liquid reflux and mixed reflux between GERD and non-GERD groups (10 (4, 19) vs. 4 (1, 9) times/24 h, 14 (6, 32) vs. 7 (3, 13) times/24 h, 0 (0, 0) vs. 0 (0, 0) times/24 h, 19 (10, 34) vs. 8 (3, 14) times/24 h, and 6 (2, 12) vs. 3 (1, 5) times/24 h, Z=-6.96, -7.25, -5.62, -8.75, and -6.48, all P<0.05, respectively). Besides, the results also showed significant differences in Boix-Ochoa score, episodes of long reflux, course of long reflux, and episodes of weakly acidic reflux between the RE and NE groups (51.2 (21.4, 153.2) vs. 20.7 (12.1, 34.7), 5 (2, 10) vs. 1 (0, 4) times/24 h, 19 (7, 87) vs. 8 (3, 22) min, and 5 (2, 15) vs. 15 (6, 33) times/24 h, Z=-3.44, -3.41, -2.65, and -2.27, all P<0.05, respectively). Conclusion: 24 h MII-pH monitoring not only improves the detection rate of GERD in children, but also provides a possibility to early etiological diagnosis.

BACKGROUNDS: Cancer is one of the main causes of death worldwide, seriously threatening human health and life expectancy. We aimed to analyze the cancer incidence and mortality rates during 2016 in Zhejiang Province, Southeast China. METHODS: Data were collected from 14 population-based cancer registries across Zhejiang Province of China. Cancer incidence and mortality rates stratified by sex and region were analyzed. The crude rate, age-standardized rate, age-specific and region-specific rate, and cumulative rate were calculated. The proportions of 10 common cancers in different groups and the incidence and mortality rates of the top five cancers in different age groups were also calculated. The Chinese national census of 2000 and the world Segi population was used for calculating the age-standardized incidence and mortality rates. RESULTS: The 14 cancer registries covered a population of 14,250,844 individuals, accounting for 29.13% of the population of Zhejiang Province. The total reported cancer cases and deaths were 55,835 and 27,013, respectively. The proportion of morphological verification (MV%) was 78.95% of the population, and percentage of incident cases identified through death certificates only (DCO%) was 1.23% with a mortality-to-incidence ratio (M/I ratio) of 0.48. The crude incidence rate in Zhejiang cancer registration areas was 391.80/105; the age-standardized incidence rate of the Chinese standard population (ASIRC) and the age-standardized incidence rate of the world standard population (ASIRW) were 229.76/105 and 220.96/105, respectively. The incidence rate in men was higher than that in women. The incidence rate increased rapidly after 45 years of age and peaked in individuals aged 80 to 84 years. The top 10 incidence rates of cancers were lung cancer, female breast cancer, thyroid cancer, colorectal cancer, stomach cancer, liver cancer, prostate cancer, cervical cancer, esophageal cancer, and pancreatic cancer (from highest to lowest). The crude mortality rate in Zhejiang cancer registration areas was 189.55/105; the age-standardized mortality rate of the Chinese standard population (ASMRC) and the age-standardized mortality rate of the world standard population (ASMRW) were 94.46/105 and 93.42/105, respectively. The mortality rate in men was higher than that in women, and the male population in rural areas was higher than that in urban areas. The cancer mortality rate increased rapidly after 50 years of age and peaked in individuals aged 85+ years. The top 10 mortality rates of cancers were lung cancer, liver cancer, stomach cancer, colorectal cancer, pancreatic cancer, esophageal cancer, female breast cancer, prostate cancer, lymphoma, and leukemia (from highest to lowest). CONCLUSIONS Lung cancer, female breast cancer, thyroid cancer, colorectal cancer, prostate cancer, liver cancer, and stomach cancer were the most common cancers in Zhejiang Province. Effective prevention and control measures should be established after considering the different characteristics of cancers in urban and rural areas.

This study analyzed the clinical features of 5 children with hereditary spherocytosis (HS) and the characteristics of ANK1 and SPTB gene mutations. All 5 children were confirmed with HS by peripheral blood genetic detection. Anemia, jaundice and splenomegaly were observed in all 5 children. Three children had an increase in erythrocyte osmotic fragility. All 5 children had negative results of the Coombs test, glucose 6 phosphate dehydrogenase test, sucrose hemolysis test, acidified-serum hemolysis test and thalassemia gene test. Peripheral blood smear showed an increase in spherocyte count in one child. High-throughput sequencing revealed ANK1 gene mutations in patients 1 to 3, namely c.3398(exon29)delA, c.4306C>T and c.957(exon9)_c.961(exon9)delAATCT, among which c.3398(exon29)delA had not been reported before. Patient 4 had c.318delGExon3 mutation in the SPTB gene. Patient 5 had mutations in the SPTB and SLC4A1 genes, among which c.3484delC in the SPTB gene was a spontaneous mutation; the mutation site of the SLCA4A1 gene was inherited from the father and was a non-pathogenic gene. This study suggests that anemia, jaundice and splenomegaly are major clinical manifestations of HS children. Most children with HS do not have the typical spherocytic changes. Genetic detection may help with the accurate diagnosis of HS.

In order to establish a real-time RT-PCR based on SYBR Green Ⅱ for detection of hepatitis E virus (HEV),a pair of special primers was designed according to the conserved sequences of ORF2 in GenBank.Result showed that the standard curve of established SYBR Green Ⅱ real-time RT-PCR had a wide dynamic range from 4.10 × 102-4.10 × 108 copies/μL with a linear correlation(r2) of 0.996.The sensitivity could reach 1.00 × 102 copies/μL.The melting curve analysis using SYBR Green Ⅱ dye showed one specific peak with a melting temperature(Tm) of 84.0 C ±0.1 C.No amplification was detected from the RNA samples of porcine reproductive and respiratory syndrome virus,classial swine fever virus,transmissible gastroenteritis virus,porcine bocavirus,porcine epidemic dearrhoea virus porcine kobuvirus and porcine rotavirus by this PCR,respectively.Excellent reproducibility was obtained for detecting constructed positive plasmid DNA with intra-assay of 0.83 ％-0.94 ％ and inter-assay of 0.83％-0.94％.Further detection of 61 specimens showed that 9 of them were HEV positive,and the results of the quantitative RT-PCR were the same as that of the conventional RT-PCR.In conclusion,the real-time quantitative RT-PCR for HEV is feasible,the real-time RT-PCR established in this study will be useful for earlier rapid laboratory diagnosis and pathogenesis of HEV.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.

Objective To understand emotional, behavioral problems and related determinants among rural stranded children and to provide evidence for further psychological support. Methods A total of 3944 caregivers of children in the rural areas and aged 4 to 7 years but without parents around, were randomly selected. Data were collected through Strengths and Difficulties Questionnaires (the edition for parents, SDQ). Results The overall prevalence of children with behavioral/emotional problems was 43.6% among those stranded children including 8.3% having experienced emotional symptoms, 9.5% reported to be displaying 'conduct' problems, 8.7% exhibited significant hyperactivity/inattention, 18.9% experienced peer relationship problems and 16.8% having prosocial behaviors. The prevalence of behavioral/emotional problems was significantly higher in boys than those in girls and in lower age groups. Significant differences were also found in conduct problems, hyperactivity/inattention and prosocial behaviors (P<0.01). The result from logistic regression analysis showed that factors as education level and motivation of the caregivers as well as financial support from the parents were related to emotional/ behavioral problems among the stranded children. Conclusion The prevalence of emotional and behavioral problems was high among children living the rural areas but without their parents around which should call for psychological intervention.

TCM terminologies are the professional medical terms, marked by in Chinese features of simplification and cogency, as well as rich connotations, and thus conciseness should be one of the main principles when it comes to their translation. The concise translation and its application were discussed in this paper through semantic and logic analysis on TCM terms and starting with the English word-building.
