ABSTRACT
Objective: To investigate the correlations between cosmetic and radiographic parameters of shoulder balance, as well as the variations in cosmetic shoulder balance observed from different perspectives, among patients with adolescent idiopathic scoliosis (AIS) characterized by thoracic curves. Methods: A total of 43 patients with thoracic curves treated from July to October in 2022 in Nanjing Drum Tower Hospital were recruited in this study. There were 9 males and 34 females with a mean age of (14.3±1.5) years. All participants underwent comprehensive radiographic assessments and were photographed both from posterior and anterior views, focusing on the shoulder region as well as a higher level (maintaining a consistent vertical distance of 180 cm from the ground). Six cosmetic parameters were measured on the photographs: shoulder angle(α1), axilla angle(α2), shoulder area index 1(SAI1), shoulder area index 2 (SAI2), inner shoulder height (SHi) and outer shoulder height (SHo). Eight radiographic parameters were measured on the radiographs: radiographic shoulder height difference (RSHD), first rib angle (FRA), clavicle-rib cage intersection (CRCI), coracoid process height (CPH), T1 tilt, clavicle angle(CA), clavicle chest cage angle difference (CCAD) and Cobb angle. Differences among bilateral cosmetic indicators from different perspectives were analyzed and compared, and their correlation with bilateral radiographic indicators was studied. Results: There was no significant differences between anterior cosmetic parameters and posterior cosmetic parameters at the same level of observation(all P>0.05). However, when observing SHi, SHo, α1, and α2 at the shoulder level, it became evident that they exhibited significantly higher values compared to the corresponding higher level on the same side of the patients' bodies. This contrast was observed in both the dorsal [SHo: (0.11±1.20) cm vs (-0.44±1.39) cm, P=0.005; SHi: (0.64±0.86) cm vs (0.32±0.56) cm, P=0.003; α1:-0.47°±2.27° vs -0.77°±2.49°, P=0.014; α2:-3.06°±3.23° vs -2.21°±3.03°, P=0.034] and ventral [SHo: (0.12±1.29) cm vs (-0.48±1.35) cm, P=0.007; SHi: (0.61±0.88) cm vs (0.30±0.59) cm, P=0.006; α1:-0.46°±2.18° vs -0.69°±2.35°, P=0.018; α2:-3.26°±3.12° vs -2.05°±2.97°, P=0.029] aspects of the patients. SHi and SHo were more sensitive to this difference of height. The correlation coefficients between radiographic parameters and cosmetic aspects at the shoulder level varied from 0.374 to 0.767. Similarly, the correlation coefficients between radiographic parameters and cosmetic factors at the higher level ranged from 0.273 to 0.579 (all P<0.05). Conclusions: The cosmetic parameters had significant difference between different perspective of observation, the cosmetic parameters are needed to be observed at the shoulder level in the evaluation of patients' shoulder balance.

OBJECTIVE: To investigate the impact of dietary and underlying factors on the iron status of women in early pregnancy and to provide evidence for preventing iron deficiency and iron deficiency anemia, thereby reducing the incidence of associated adverse outcomes. METHODS: From November to December 2018, women in the first trimester of pregnancy (< 12 weeks gestation) who established prenatal records at the Shunyi District Maternal and Child Health Hospital, Beijing, were enrolled in this study, in which 388 participants were accessed for data including demographic characteristics, anthropometric measurements, parity, biomarkers reflecting iron status, and food-frequency questionnaire. SPSS 26.0 were used for statistical analysis. Dietary patterns were extracted using principal component analysis, and factor scores of each dietary pattern were calculated. Two-sided Fisher exact probability test and one-way ANOVA were conducted to access differences in iron status among the groups, and the differences were significant if P < 0.05. Iron deficiency was defined as serum ferritin(SF) < 30 µg/L. To analyze the potential role of dietary factors on iron deficiency during the first trimester, the collected data listed above were adopted as independent factors for the cross-sectional Logistic regression. We used Logistic regression to analyze the potential effects of baseline characteristics and dietary factors on iron status. RESULTS: Among the 388 participants included in the analysis, 121 (32.2%) were iron deficient, in which 107 (27.6%) were iron depletion (ID), 8 (2.1%) were iron deficiency erythropoiesis (IDA), 6(1.5%) were iron deficiency anemia. The mean SF concentration was (50.4±35.3) µg/L. Multiparity(OR=3.9, 95%CI: 1.81-8.42, P=0.001)was a risk factor for iron deficiency during early pregnancy. No significant iron status differences were found among the participants with different educational levels and anthropometric measurements. In contrast, age (OR =0.96, 95%CI: 0.94-0.97, P < 0.001) was a protective factor. For multiparas, taking iron-containing supplements might have a protective effect for iron deficiency (OR=0.27, 95%CI: 0.09-0.83, P=0.022). The balance-diet pattern (OR=0.81, 95%CI: 0.66-1.00, P=0.054) only showed a marginally significant effect. CONCLUSION: Increasing attention should be paid to the iron status of pregnant multiparas and young pregnant women. For those women of reproductive age with the risk factors listed above, especially for multiparas, iron-containing supplements should be recommended to prevent gestational iron deficiency. The effect of the "balance" dietary pattern on iron status in the first trimester and following requires further research and discussion.

Multidrug-resistant (MDR) Staphylococcus aureus and its biofilm formation have been challenging to control in milk and dairy industries. Biofilms formed by Staph. aureus may result in the failure of antibacterial agents and disinfectants to penetrate the biofilm in an attempt to control contamination. Novel natural antibacterial agents are required to combat MDR bacteria and biofilms. In this study, we evaluated the bactericidal, antibiofilm, and antimotility effects of Rumex japonicus Houtt. (RJH) extract on MDR Staph. aureus isolated from milk. The RJH extract exhibited good antibacterial activity against MDR strains with minimum inhibitory concentrations (MIC) ranging from 0.78 to 6.25 mg/mL and minimum bactericidal concentrations ranging from 3.125 to 12.5 mg/mL. The extract showed strong inhibition of biofilm formation (81.9%) at sub-MIC value and eradication of biofilm at higher concentrations. The motility of Staph. aureus was effectively blocked by the extract. Major compounds emodin, chrysophanol, and physcion were identified in RJH extract using HPLC-linear trap quadrupole (LTQ)/Orbitrap-mass spectrometry. The extract was nontoxic to human epithelial cell lines such as Caco-2 and HT-29 cell lines at concentrations ranging from 0.1 to 0.5 mg/mL, and from 0.1 to 0.75 mg/mL, respectively. These findings suggest that RJH extract could be an alternative to synthetic preservatives in milk and dairy products.

BACKGROUND: Little is known about the disease burden of chronic obstructive pulmonary disease (COPD) and asthma in southern China. METHOD: We calculated the mortality, disability-adjusted life-years (DALY), years lived with disability (YLD) and years of life lost (YLL) for COPD and asthma in Guangdong province between 2005 and 2015. We examined the significance of trends of mortality, DALY, YLD and YLL rates for COPD and asthma with the Cochran-Armitage trend test. We also analyzed their association with sociodemographic factors by negative binomial models. RESULT: The age-standardized mortality, DALY, YLD and YLL rates of COPD and asthma decreased significantly in Guangdong, except for an increase of 11.3% in the age-standardized YLD rate of COPD between 2005 and 2015 (all P < 0.05). Compared with females, the respective adjusted mortality rate ratio of males was 2.11 for COPD, and 0.74 for asthma. Compared with other regions, the richest region, Pearl River Delta, had the lowest mortality, DALY, YLD and YLL rate ratios (RR) of COPD and asthma (all P < 0.05). COPD and asthma mortality, DALY, YLD and YLL rates increased substantially with age. Specifically, when compared with the 25-49 years age group, the respective adjusted DALY RR of asthma was 1.91, 2.02 and 22.21 for 0-24, 50-74 and ≥75 years age group; the respective adjusted YLD RR was 2.27, 1.33 and 7.17 for 0-24, 50-74 and ≥75 years age group. CONCLUSIONS: Disease burden of COPD and asthma decreased in Guangdong province in southern China between 2005 and 2015; however, a disproportionate burden of COPD and asthma in terms of age, sex and regions was observed. The relatively high disease burden and high rate of impaired public health from the less developed regions highlight the need for focused policy making to address the problem.

Objective: To evaluate the efficacy and safety of belimumab in children with systemic lupus erythematosus (cSLE). Methods: The clinical data of 49 cSLE patients admitted into the Department of Rheumatology and Immunology, Children's Hospital affiliated to the Capital Institute of Pediatrics, from August 2018 to December 2021 were collected. They were divided into the belimumab treatment group (18 cases) and the traditional treatment group (31 cases) according to whether they received belimumab treatment. The cSLE patients in the traditional group had similar baseline SLEDAI scores with the belimumab group and were treated with traditional immunosuppressive drugs. The clinical symptoms and improvements before and after treatment, as well as the differences in adverse events during follow-up were compared between the two groups. Results: In belimumab group, the age was (11.9±1.8) years old, the median (Q1, Q3) of disease duration was 7.5 (2.0, 16.8) months, 3 patients were male, and 15 patients completed 24 weeks of treatment. In the traditional treatment group, 31 patients with cSLE were enrolled, with an average age of (11.3±2.4) years, a median (Q1, Q3) of disease duration of 7.0 (2.5, 10.5) months, among whom 6 patients were male, and 25 patients completed 24 weeks of treatment. At baseline, the belimumab treatment group had a significantly lower oral prednisone dose than the conventional treatment group [(29.58±12.43) mg/d vs (38.20±14.11) mg/d, P=0.037]. After 24 weeks of treatment, the dosage of prednisone in both groups was reduced, and the dosage of prednisone in the belimumab group was (14.12±5.86) mg/d, which was lower than that in the traditional treatment group [(23.51±9.79) mg/d] (P=0.002). After 24 weeks of treatment, the levels of complement C3 and C4 increased, the dsDNA levels and SLEDAI score decreased in both groups (all P>0.05). The incidence of adverse events in belimumab group (3/15, 3 cases) was lower than that in traditional treatment group (32.0%, 8/25) (P>0.05). Conclusions: Belimumab in the treatment of cSLE can reduce the initial dose of prednisone and facilitate the reduction of prednisone dose, significantly improve the clinical symptoms and organ involvement, and reduce the disease activity. The incidence of adverse events was low during belimumab treatment.

This study aims to explore optimized teaching mode of cancer epidemiology for undergraduates, and provide scientific ideas and basis for improving teaching quality. Non-randomized concurrent control study was used. Undergraduates, enrolled in 2018, from the department of preventive medicine in A and B medical universities were selected as research objects. Traditional teaching mode was used for cancer epidemiology course in A medical university, and innovative teaching mode named "one core, four dimensions" was adopted in B medical university. After the course, questionnaire method was used to investigate self-cognition of students, teaching satisfaction and class preparation time of teachers in B Medical University. The post-class test method was used to compare the students' grades of cancer epidemiology in the two universities. The results indicated that among the 58 students of B medical university, 94.83% (55/58) students were familiar with common types of epidemiological studies and 86.21% (50/58) mastered the evaluation indicators of screening research. Among the nine teaching faculties from B medical university, seven reported that the new teaching plan helped students to learn frontier knowledge of cancer epidemiology, and eight reported the new teaching model was conducive to the interaction between teachers and students. The text score of students in B medical university was 50.34±4.90, significantly higher than that in A medical university (46.21±4.91, t=5.20, P<0.001). The optimized teaching mode of cancer epidemiology is highly praised by students and teachers, which has the potential to improve students' grasp of cancer epidemiology, the ability to combine theory with practice, and the teaching effect of cancer epidemiology.

Objective: To explore the effect of lead exposure on the neurobehavior and gut microbiota community structure in mice. Methods: In August 2019, 64 C57BL/6 mice were randomly divided into 4 groups: control group (0 ppm) , low lead exposure group (20 mg/l) , medium lead exposure group (100 mg/l) and high lead exposure group (500 mg/l) . During the experiment, they were free to eat and drink. The drinking water of the lead exposure group was mixed with lead acetate, and sodium acetate was added in the control group. After 10 weeks of exposure, the Morris water maze was used to test the learning and memory ability of each group of mice, and then they were sacrificed for sampling. ICP-MS was used to detect lead content in whole blood and brain tissue. ELISA was used to determine the level of IL-1ß in mouse serum. 16S rRNA sequencing was used to detect the structural diversity of the intestinal flora in feces, and then the correlation between the flora and behavior indicators was analyzed. Results: In the Morris water maze experiment, compared with the control group, there was no significant difference in the body weight and swimming speed of the mice in the lead exposure groups. The escape latency of the mice in the 100 mg/l and 500 mg/l dose groups was prolonged, and the number of platform crossings decreased (P<0.05) ; meanwhile, the staying time of the mice in the 500 mg/l Pb-treated group in the target quadrant was lower than that of the control group, and the difference was statistically significant (P<0.05) . Compared with the control group, the blood lead content of the mice in each lead exposure group was significantly increased, and the brain lead content of mice in the 500 mg/l dose group was significantly elevated (P<0.05) . The serum IL-1ß levels of mice in each lead exposure group were higher than those of the control group (P<0.05) . At the phylum level, the relative abundance of the Proteobacteria phylum in all of Pb-treated groups was significantly increased (P<0.05) ; at the genus level, Allobaculum, Desulfovibrio, Lachnospiraceae_NK4A136_group, Turicibacter and Ureaplasma were significantly increased (P<0.05) . Among them. The relative abundance of Desuffaoibrio, Turici bacter, and Ureaplasma was negatively correlated with the residence time of mice in the quadrant of the platform (r=-0.32, -0.29, -0.44, P<0.05) . Conclusion: Lead exposure induced learning and memory impairments in mice, which may be related to the disturbance of the gut microbiota.

Objective: To investigate the effects and the mechanism of Calcyclin-binding protein (CacyBP) on the proliferation and invasion of non-small cell lung cancer (NSCLC) cells. Methods: Six lung cancer tissues and paired normal lung tissues were collected from NSCLC patients who underwent surgical treatment in Jinan Central Hospital during 2016. The expression of CacyBP in these tissues was examined by western blot. The protein and mRNA expression of CacyBP in human bronchial epithelial cells (16HBE), NSCLC cell lines including A549, H1299, H460 and H1975 were examined by western blot and reverse transcription-polymerase chain reaction (RT-PCR), respectively. RNAi and shRNA against negative control (NC) or CacyBP were transfected into A549 cell which were denoted as siNC group, siCacyBP-1 group, sicacyBP-2 group, shNC group and shCacyBP group, respectively. Control and Flag-CacyBP plasmids were transfected into A549 cells which were denoted as NC group and Flag-CacyBP group, respectively. Cell counting kit-8 (CCK-8), plate clone formation assay and flow cytometry assay were used to assess cell proliferation ability and cycle of A549. Wound healing assay and transwell assay were used to assess abilities of A549 cells migration and invasion. The protein expressions of epithelial-mesenchymal transition (EMT) markers including E-cadherin, N-cadherin, Snail1, Vimentin, and phosphorylation of protein kinase B (p-Akt) were examined in CacyBP depleted or overexpressed A549 cells. Results: The CacyBP protein level in NSCLC tissues was 0.41±0.23, significantly higher than 0.11±0.04 in normal lung tissues (P<0.05). The CacyBP protein expression levels in different NSCLC cell lines including A549, H1299, H460 and H1975 were 0.35±0.01, 0.38±0.01, 0.32±0.01 and 0.41±0.01, respectively, which were significantly higher than 0.03±0.01 in 16HBE cells (P<0.05). The result of RT-PCR was consistent with that of western blot. Compared with siNC group (absorbance was 1.54±0.03), siCacyBP-1 group and siCacyBP-2 group showed decreased cell proliferation (absorbances were 1.38±0.04 and 1.34±0.03, P<0.05). The number of cell colony in shNC group was 41.33±3.21, significantly higher than 22.00±3.61 in shCacyBP group (P<0.05). The proportion of G(1) phase in shCacyBP group was (61.35±5.45)%, higher than (49.61±1.54) % in shNC group (P<0.05). The proportion of S phase was (25.41±3.21)%, which was lower than (38.68±0.46)% of shNC group (P<0.05). The cell migration rate of shCacyBP group was (12.67±0.71)%, which was significantly lower than (35.50±2.07)% of shNC group (P<0.05). The numbers of cell migration and invasion in shNC group were 406.33±7.37 and 92.33±8.50, respectively, which were significantly higher than 224.67±10.01 and 66.00±7.94 in shCacyBP group (P<0.05). Compared with siNC group, the expression of epithelial marker E-cadherin was up-regulated, while the expressions of mesenchymal markers including N-cadherin, Vimentin, Snail1 and p-Akt were down-regulated in CacyBP depleted A549 cells. Compared with NC group, overexpression of CacyBP inhibited E-cadherin expression while promoted the expressions of N-cadherin, Snail1, Vimentin and p-Akt, which could be restored by LY294002. Conclusion: CacyBP may promote the proliferation and invasion of NSCLC cells by regulating Akt signal pathway.

Objective: To analyze the compliance and related factors of low-dose computed tomography (LDCT) screening among the high-risk population of lung cancer in three provinces participating in the cancer early diagnosis and early treatment program in urban areas of China. Methods: From October 2017 to October 2018, 17 983 people aged between 40 and 74 years old at high risk of lung cancer were recruited from Zhejiang, Anhui and Liaoning provinces. The basic demographic characteristics, living habits, history of the disease and family history of cancer were collected by using a cancer risk assessment questionnaire, and the data of participants examined by LDCT were obtained from the hospitals participating in the program. The screening compliance was quantified by the screening participation rate, and it was calculated as the proportion of participants completing LDCT scan among high-risk population. The related factors of LDCT screening compliance were analyzed by using a multivariate logistic regression model. Results: The age of 17 983 participants was (56.52±8.22) years old. Males accounted for 51.9% (N=9 332), and 69.5% (N=12 495) had ever smoked, including former smokers and current smokers. A total of 6 269 participants were screened by LDCT, and the screening participation rate was 34.86%. The results of multivariate logistic regression analysis showed that the age group of 50 to 69 years old, female, passive smokers, alcohol consumption, family history of lung cancer and history of chronic respiratory diseases were more likely to be screened by LDCT, while the compliance of LDCT screening in current smokers was low. Conclusions: The LDCT screening compliance of the high-risk population of lung cancer in urban areas of China still needs to be improved. Age, sex, smoking, drinking, family history of lung cancer and history of chronic respiratory disease are associated with screening compliance.

BACKGROUND: The optimal analgesia regimen after laparoscopic colorectal cancer surgery is unclear. The aim of the study was to characterize the beneficial effects of continuous transversus abdominis plane (TAP) blocks initiated before operation on outcomes following laparoscopic colorectal cancer surgery. METHODS: Patients undergoing surgery for colorectal cancer were divided randomly into three groups: combined general-TAP anaesthesia (TAP group), combined general-thoracic epidural anaesthesia (TEA group) and standard general anaesthesia (GA group). The primary endpoint was duration of hospital stay. Secondary endpoints included gastrointestinal motility, pain scores and plasma levels of cytokines. RESULTS: In total, 180 patients were randomized and 165 completed the trial. The intention-to-treat analysis showed that duration of hospital stay was significantly longer in the TEA group than in the TAP and GA groups (median 4·1 (95 per cent c.i. 3·8 to 4·3) versus 3·1 (3·0 to 3·3) and versus 3·3 (3·2 to 3·6) days respectively; both P < 0·001). Time to first flatus was earlier in the TAP group (P < 0·001). Visual analogue scale (VAS) scores during coughing were lower in the TAP and TEA groups than the GA group (P < 0·001). Raised plasma levels of vascular endothelial growth factor C, interleukin 6, adrenaline and cortisol were attenuated significantly by continuous TAP block. CONCLUSION: Continuous TAP analgesia not only improved gastrointestinal motility but also shortened duration of hospital stay. A decreased opioid requirement and attenuating surgical stress response may be potential mechanisms. Registration number: ChiCTR-TRC-1800015535 ( http://www.chictr.org.cn).
ANTECEDENTES: El régimen analgésico óptimo para los pacientes tras cirugía laparoscópica del cáncer colorrectal se desconoce. El objetivo de este estudio fue caracterizar los efectos beneficiosos del bloqueo continuo del plano transverso abdominal (transversus abdominis plane, TAP) iniciado preoperatoriamente sobre los resultados después de cirugía laparoscópica del cáncer colorrectal. MÉTODOS: Los pacientes sometidos a cirugía del cáncer colorrectal fueron divididos aleatoriamente en tres grupos: anestesia combinada general-TAP (grupo TAP), anestesia epidural combinada general-torácica (grupo TEA) y anestesia general estándar (grupo GA). El resultado primario fue la duración de la estancia hospitalaria. Los resultados secundarios incluyeron la motilidad gastrointestinal, puntuaciones de dolor y niveles plasmáticos de citocinas. RESULTADOS: En total, 180 pacientes fueron aleatorizados y 165 completaron el ensayo. El análisis por intención de tratar mostró que la duración de la estancia hospitalaria en el grupo TEA fue significativamente más larga que en el grupo TAP y GA respectivamente (4,1 (3,8-4,3) versus 3,1 (3,0-3,3) días, P < 0,001; 4,1 (3,8-4,3) versus 3,3 (3,2-3,6) días, P < 0,001). El tiempo hasta la primera eliminación de gases fue más precoz en el grupo TAP (P < 0,001). Las puntuaciones de la escala analógica visual (visual analogue scale, VAS) durante la tos en el grupo TAP y TEA fueron inferiores (P < 0,01). Los niveles elevados en plasma del factor de crecimiento endotelial C (VEGF-C), interleucina (IL)-6, epinefrina y cortisol fueron atenuados significativamente por el bloque TAP continuo. CONCLUSIÓN: La analgesia TAP continua no solo mejora la motilidad gastrointestinal, sino que también acorta la estancia hospitalaria. Una disminución en los requerimientos de opiáceos y la atenuación de la respuesta al estrés quirúrgico podrían ser mecanismos potenciales de la acción de TAP.

Hallux valgus is a common foot deformity disease caused by various extrinsic and intrinsic factors, and systemic conditions, but the etiopathogenesis and pathogenesis of this deformity are still unknown. Hallux valgus affects 10-20% of Chinese adults. Although considered highly heritable, the candidate gene is unclear. We conducted the first candidate gene study of hallux valgus to identify the biological mechanism. Between June 2015 and July 2018, the records and radiographs of 80 patients diagnosed with hallux valgus and 80 controls who were treated were analyzed. In order to compare the differences in severity associated with this deformity, the charts of 80 patients were divided into 3 groups from the angle of hallux valgus. Clinical and basic studies were also statistically compared by PCR and data analysis. Patients and controls had significant differences in age and gender, however, there were no significant differences in age and gender among the light, moderate and severe groups. Post-operative groups resulted in significant improvements in all of the measured radiographic parameters compared with pre-operative groups. BsmI seemed to show a specific variation, and may serve as a useful bio-marker for the disease (OR = 5.88, 95% CI 1.54-22.35, P <0.001). In this paper, the article which proved the VDR polymorphisms (BsmI) playing an important role in hallux valgus were studied to understand and manage the hallux valgus more scientifically.

Objective: To investigate the feasibility of circulating tumor DNA (ctDNA) in detecting small cell lung cancer (SCLC) gene mutations and its prognostic value in chemotherapy and/or radiotherapy for SCLC patients. Methods: A total of 77 SCLC patients who were admitted to the Department of Thoracic Medical Oncology and the Department of Thoracic Radiation Oncology of Zhejiang Cancer Hospital from July 2016 to November 2019 were included. There were 66 males and 11 females, with a median age of 60 years. Among them, 42 cases were in limited stage (LS) and 35 cases were in extensive stage (ES). Next-generation sequencing (NGS) of patients' plasma ctDNA was performed before treatment. The differences of mutated genes and signaling pathways between LS and ES patients were analyzed and compared. Blood-based tumor mutation burden (bTMB) was calculated according to detected somatic cell mutations. Patients were divided into the high bTMB and the low bTMB groups according to the optimal threshold calculated by R software. Log-rank tests were used to compare progression-free survival (PFS) between the high bTMB and the low bTMB groups. Results: Among the 77 patients, 76 patients had gene mutations detected in their plasma, and the positive rate of ctDNA test was 98%. Among the 76 patients, the genes with the highest mutation frequency were TP53 (89%), RB1 (70%), LRP1B (34%), CREBBP (21%), MLL3 (21%), MLL2 (16%), NOTCH1 (13%), ROS1 (13%), BRCA2 (12%), and PTPRD (12%). The most common mutated genes in LS patients were TP53 (90%), RB1 (68%), LRP1B (24%), MLL2 (22%), and BRCA2 (17%); the most common mutated genes in ES patients were TP53 (89%), RB1 (71%), LRP1B (46%), CREBBP (31%), and MLL3 (29%). The mutation rates of NOTCH1 and CREBBP genes were significantly higher in ES patients (31.4% and 22.9%) than those in LS patients (11.9% and 4.8%) (both P<0.05). Signaling pathway analysis showed that there were more NOTCH pathway gene variations in ES patients. Among LS patients, patients in the high bTMB group (≥ 6.96 mutations/Mb) had a longer PFS than that in the low bTMB group (<6.96 mutations/Mb) (P=0.033); but no such difference was noted in ES patients. Conclusion: Plasma ctDNA sequencing detected SCLC gene mutation profiles similar to those reported in previous literature, thus ctDNA could be used as a tool to study SCLC genomics; the mutation spectra of ES-SCLC and LS-SCLC were different. bTMB has potential prognostic value in LS-SCLCs treated with chemoradiotherapy.

Objective: To determine whether 60 Gy is superior to standard 50 Gy for definitive concurrent chemoradiation(CCRT) in esophageal squamous cell carcinoma (ESCC) using modern radiation technology in a phase â ¢ prospective randomized trial. Methods: From April 2013 to May 2017, 331 patients from 22 hospitals who were pathologically confirmed with stage â ¢A-â £A ESCC were randomized to 60 Gy or 50 Gy with random number table. Total of 305 patients were analyzed, including 152 in 60 Gy group and 153 in 50 Gy group. The median age was 63 years, 242(79.3%) males and 63(20.7%) females. The median length of primary tumor was 5.6 cm. The clinical characteristics between two groups were comparable. All patients were delivered 2 Gy per fraction, 5 fractions per week. Concurrent weekly chemotherapy with docetaxel (25 mg/m(2)) and cisplatin (25 mg/m(2)) and 2 cycles consolidation chemotherapy with docetaxel (70 mg/m(2)) and cisplatin (25 mg/m(2), d1-3) were administrated. The primary endpoint was local/regional progression-free survival (LRPFS). The data were compared with Pearson chi-square test or Fisher's exact test. Results: At a median follow-up of 27.3 months, the disease progression rate was 37.5% (57/152), 43.8% (67/153) in the high and standard-dose group, respectively (χ(2)=1.251, P=0.263). The 1, 2, 3-year LRPFS rate was 75.4%, 56.8%, 52.1% and 74.2%, 58.4%, 50.1%, respectively (HR: 0.95, 95%CI: 0.69-1.31, P=0.761). The 1, 2, 3-year overall survival rate was 84.1%, 64.8%, 54.1% and 85.4%, 62.9%, 54.0%, respectively (HR: 0.98, 95%CI: 0.71-1.38, P=0.927). The 1, 2, 3-year progression-free survival rate was 70.8%, 54.2%, 48.5% and 65.5%, 51.9%, 45.1%, respectively (HR: 0.93, 95%CI: 0.68-1.26, P=0.621). The incidence rates in toxicities between the two groups were similar except for higher rate of severe pneumonitis in high dose group (χ(2)=11.596, P=0.021). Conclusions: The efficacy in disease control is similar between 60 Gy and 50 Gy using modern radiation technology concurrent with chemotherapy for ESCC. The 50 Gy should be recommended as the regular radiation dose with CCRT for ESCC.

Nutrition literacy is an important part of health literacy, as well as an significant factor to enhance the quality of population, improving the nutritional status of residents and preventing nutrition-related diseases. In 2010, China developed an evaluation tool for health literacy and began to monitor residents' health literacy. So far, eight national surveys on health literacy have been completed, providing an important basis for health promotion intervention strategies and related policies. However, in health literacy evaluation system, there is neither evaluation content of nutrition literacy, nor evaluation tools. In order to achieve the goals of "national nutrition plan (2017-2030)"and evaluate the implementation effect, it is urgent to carry out the assessment and monitoring of nutrition literacy. According to the nutritional characteristics of different populaitons, this research organizes national experts in related fields, following the principles of scientificity, conciseness and generality and through the scientific formulation procedures to construct the nutrition literacy assessment tools for different populations. This assessment tool can enhance the pertinence and scientificity of nutrition education and improve nutrition development strategy. The establishment of the nutrition literacy assessment tool is the premise of gradually establishing the nutrition literacy assessment system of the residents, and also lays a solid foundation for further conducting the national nutrition literacy evaluation work.

Objective: To estimate the incidence, mortality and characteristics of cancer in Pearl River Delta Area of Guangdong Province between 2009-2013. Methods: Based on five population-based cancer registration data from Guangzhou, Shenzhen, Zhongshan, Jiangmen and Sihui spanning from 2009 to 2013, along with those corresponding population data, the incidence and mortality rates were estimated by gender and age groups. Chinese standard population derived from the 2000 Population Census and Segi's standard population were used for age-standardized incidence and mortality rates. Results: Between 2009 and 2013, the crude cancer incidence rate was 262.50/100 000, 274.76/100 000 in male and 249.49/100 000 in female. After adjusting for Chinese and Segi's standard population, the age-standardized incidence rates were 225.63/100 000 and 219.88/100 000, respectively. The crude mortality rate was 175.51/100 000, 222.92/100 000 in male and 127.46/100 000 in female, respectively. After adjusting for Chinese and Segi's standard population, the age-standardized mortality rates were 116.02 /100 000 and 114.31/100 000, respectively. The incidence rates were at low levels in the population less than 40 years old, thereafter went up rapidly with age especially in male, and then reached the peak in the population aged 80 and above. As with incidence, the mortality rates kept at low levels in the population before their 50 s and then rose up steadily with age until peaking in the 85+ age group. The most common cancers were female breast cancer, lung cancer, colorectal cancer, liver cancer and nasopharyngeal cancer with descending incidence rate. Lung cancer, liver cancer, colorectal cancer, female breast cancer and nasopharyngeal cancer were the top five cancer-attributable causes of death. Conclusions: Currently, Pearl River Delta Area were faced with huge cancer burden. Lung cancer, colorectal cancer, nasopharyngeal cancer, female breast cancer and male liver cancer are predominant cancers and more efforts should be made to fight against them.
