ABSTRACT

Objective:To investigate and analyze the current status of multimodality therapy for resectable gastric cancer, aiming to provide reference for optimizing the multimodality treatment strategy for gastric cancer.Methods:Clinical data of patients diagnosed with gastric adenocarcinoma undergoing radical gastrectomy in the Second Affiliated Hospital of Soochow University were retrospectively analyzed. Clinical characteristics, preoperative medical comorbidities, pathological features, surgical and perioperative status and clinical efficacy were recorded. The gap between the diagnosis and treatment procedures and the standard guidelines was analyzed. The changes in the multimodality treatment patterns for gastric cancer were understood.Results:A total of 265 patients were included in this study. All patients were divided into two cohorts: early[2008] and late[2013] cohorts. In the early cohort, 127 patients were assigned, and 138 cases in the late cohort. In the early cohort, 67 patients (52.8%) underwent D 2 lymph node dissection, significantly less than 83 patients (60.1%) in the late cohort ( P<0.01). In the early and late cohorts, the proportion of patients with the number of lymph node dissection of ≥15 was 5.5% and 52.8%( P<0.01). The median number of lymph node dissection was increased from 6 to 16. The proportion of patients receiving neoadjuvant chemotherapy in the early and late cohorts was 2.4% and 3.6%( P=0.55). In the early cohort, the proportion of patients treated with postoperative chemotherapy and postoperative adjuvant chemoradiotherapy was 62.6% and 2.4%, significantly higher compared with 58.0% and 8.0% in the late cohort ( P=0.04). In addition, the proportion of patients receiving postoperative chemotherapy in the early cohort was 62.2%( n=79) and 58.0%( n=80) in the late cohort ( P=0.48). Conclusions:Although the level of radical gastrectomy has been continuously improved and standardized in China, which still lags behind the standard D 2 radical gastrectomy in Japan and South Korea. Adjuvant therapies including postoperative adjuvant radiotherapy can bring clinical benefits. However, the proportion of patients receiving adjuvant therapy is still low, and the multimodality therapy of gastric cancer should be widely applied.

ABSTRACT

Objective:To analyze the levels of individual doses to radiation workers receiving medical radiation exposure in hospitals in Jiangxi province, so as to provide reference for radiation protection.Methods:The radiation workers of different types in medical institutions in Jiangxi were investigated from 2014 to 2018, involving diagnostic radiology, radiotherapy, nuclear medicine and interventional radiology. Statistical analyses were made of the individual doses to medical radiation workers in the province.Results:The total number of monitored workers were 23 833 with average annual individual effective dose of 0.316 mSv. NR1 and NR5, the ratios of the number of workers receiving annual individual doses exceeding 1 and 5 mSv to the total monitored workers were 4.32% and 0.10%, respectively. During the five-year period, the average annual individual effective dose showed a upward and then downward trend, with peak appearing in 2017. A total of 17 909 diagnostic radiologists were monitored, accounting for 75.14% of the total number of monitored workers. The average annual individual effective dose received by workers was 0.329 mSv, the highest, in interventional radiology, followed by diagnostic radiology 0.318 mSv, nuclear medicine 0.283 mSv, and radiotherapy 0.269 mSv, respectively. There were statistically significant differences among radiation workers of different types ( χ2=489.39, P<0.001). Conclusions:The average annual individual effective dose to the radiation workers in medical institutions in Jiangxi province meets the relevant national standards, but with an upward trend in nuclear medicine. The higher levels of individual doses to radiation workers are seen in primary and secondary hospitals. It should be strengthen the oversight of radiation workers in nuclear medicine and in primary and secondary hospitals.

ABSTRACT

Objective:To evaluate the value of cardiac MR feature tracking (CMR-FT) on the early assessment of left ventricular subclinical myocardial dysfunction in patients of hypertensive heart disease (HHD).Methods:From October 2018 to November 2019, 16 HHD patients with left ventricular hypertrophy (HHD-LVH), 24 HHD patients without left ventricular hypertrophy (HHD-nonLVH) and 24 age-and gender-matched normotensive controls who underwent 3.0 T CMR examination were retrospectively enrolled. Imaging protocol included cine sequence and late gadolinium enhancement. Left ventricular function variables were measured using Argus software, mainly including left ventricular end-diastolic volume index (LVEDVI), left ventricular mass index (LVMI), left ventricular maximal wall thickness (LVMWT), the ratio of left ventricular mass to left ventricular end-diastolic volume (M/V). CMR-FT was performed using commercial software CVI 42, with parameters including global radial, circumferential, longitudinal strains (GRS, GCS, GLS), peak systolic radial, circumferential, longitudinal strain rate (SRSR peak, SCSR peak, SLSR peak) and peak diastolic radial, circumferential, longitudinal strain rate (DRSR peak, DCSR peak, DLSR peak) derived. One-way analysis of variance with scheffe correction or Kruskal-Wallis test was performed for multiple comparisons. Pearson or Spearman analysis was used for linear or monotonic nonlinear correlations. Results:HHD-LVH group had higher LVEDVI, LVMI, LVMWT and M/V than HHD-nonLVH group and control group ( P<0.05). Compared with control group, GRS, GCS and GLS were statistically impaired in HHD-LVH group, and DRSR peak, DCSR peak and DLSR peak were statistically reduced in HHD-LVH group and HHD-nonLVH group(all P<0.05). Correlation analysis showed that LVMI correlated linearly with GRS ( r=-0.384, P=0.002), GCS ( r=0.392, P=0.001) and GLS ( r=0.491, P<0.0001),LVMWT correlated nonlinearly with GRS ( r=-0.362, P=0.003), GCS ( r=0.384, P=0.002) and GLS ( r=0.422, P=0.001), LVEDVI correlated nonlinearly with GRS ( r=-0.295, P=0.018) and GCS ( r=0.264, P=0.035). Conclusion:CMR-FT derived left ventricular strain parameters could be served as early indicators for the assessment of subclinical myocardial dysfunction in HHD patients, which have great potential in guiding appropriate intervention therapy and improving cardiac remodeling.

ABSTRACT

OBJECTIVE@#To explore the application value of next generation sequencing (NGS) in preimplantation genetic diagnosis of α/β complex thalassemia couple.@*METHODS@#The coding regions of α-globin genes (HBA1, HBA2) and β-globin gene (HBB) were selected as the target regions. The high-density and closely linked single nucleotide polymorphism (SNP) sites were selected as the genetic linkage markers in the upstream and downstream 2M regions of the gene. After NGS, the effective SNP sites were selected to construct the haplotype of the couple, and the risk chromosome of the mutation carried by the couple was determined. The NGS technology was used to sequence the variations of HBA1, HBA2 and HBB directly and construct haplotype linkage analysis for preimplantation genetic diagnosis.@*RESULTS@#Direct sequencing and haplotype linkage analysis of HBA1, HBA2 and HBB showed that two of the six blastocysts were α/β complex thalassemia, one was β-thalassemia heterozygote, two were α-thalassemias heterozygotes, and one was intermediate α-thalassemia. A well-developed embryo underwent preimplantation genetic diagnosis was implanted into the mother's uterus, and a healthy infant was born at term.@*CONCLUSION@#Preimplantation genetic diagnosis can be carried out by NGS technology in α/β complex thalassemia couples, and abortion caused by aneuploid embryo selection can be avoided.

ABSTRACT

Objective@#To evaluate the cardiovascular damage of patients with COVID-19, and determine the correlation of serum N-terminal pro B-type natriuretic peptide (NT-proBNP) and cardiac troponin-I (cTnI) with the severity of COVID-19, and the impact of concomitant cardiovascular disease on severity of COVID-19 was also evaluated.@*Methods@#A cross-sectional study was designed on 150 consecutive patients with COVID-19 in the fever clinic of Tongji Hospital in Wuhan from January to February in 2020, including 126 mild cases and 24 cases in critical care. Both univariate and multivariate logistic regression were used to analyze the correlation of past medical history including hypertension, diabetes and coronary heart disease (CHD) , as well as the levels of serum NT-proBNP and cTnI to the disease severity of COVID-19 patients.@*Results@#Age, hypersensitive C-reactive protein(hs-CRP) and serum creatinine levels of the patients were higher in critical care cases than in mild cases(all P<0.05). Prevalence of male, elevated NT-proBNP and cTnI, hypertension and coronary heart disease were significantly higher in critical cases care patients than in the mild cases(all P<0.05). Univariate logistic regression analysis showed that age, male, elevated NT-proBNP, elevated cTnI, elevated hs-CRP, elevated serum creatinine, hypertension, and CHD were significantly correlated with critical disease status(all P<0.05). Multivariate logistic regression analysis showed that elevated cTnI(OR=26.909, 95%CI 4.086-177.226, P=0.001) and CHD (OR=16.609, 95%CI 2.288-120.577, P=0.005) were the independent risk factors of critical disease status.@*Conclusions@#COVID-19 can significantly affect the heart function and lead to myocardial injury. The past medical history of CHD and increased level of cTnI are two independent determinants of clinical disease status in patients with COVID-19.

ABSTRACT

Due to the poor repair ability of cartilage tissue, regenerative medicine still faces great challenges in the repair of large articular cartilage defects. Quercetin is widely applied as a traditional Chinese medicine in tissue regeneration including liver, bone and skin tissues. However, the evidence for its effects and internal mechanisms for cartilage regeneration are limited. In the present study, the effects of quercetin on chondrocyte function were systematically evaluated by CCK8 assay, PCR assay, cartilaginous matrix staining assays, immunofluorescence assay, and western blotting. The results showed that quercetin significantly up-regulated the expression of chondrogenesis genes and stimulated the secretion of GAG (glycosaminoglycan) through activating the ERK, P38 and AKT signalling pathways in a dose-dependent manner. Furthermore, in vivo experiments revealed that quercetin-loaded silk protein scaffolds dramatically stimulated the formation of new cartilage-like tissue with higher histological scores in rat femoral cartilage defects. These data suggest that quercetin can effectively stimulate chondrogenesis in vitro and in vivo, demonstrating the potential application of quercetin in the regeneration of cartilage defects.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is a highly contagious disease and a serious threat to human health. COVID-19 can cause multiple organ dysfunction, such as respiratory and circulatory failure, liver and kidney injury, disseminated intravascular coagulation, and thromboembolism, and even death. The World Health Organization reports that the mortality rate of severe-type COVID-19 is over 50%. Currently, the number of severe cases worldwide has increased rapidly, but the experience in the treatment of infected patients is still limited. Given the lack of specific antiviral drugs, multi-organ function support treatment is important for patients with COVID-19. To improve the cure rate and reduce the mortality of patients with severe- and critical-type COVID-19, this paper summarizes the experience of organ function support in patients with severe- and critical-type COVID-19 in Optical Valley Branch of Tongji Hospital, Wuhan, China. This paper systematically summarizes the procedures of functional support therapies for multiple organs and systems, including respiratory, circulatory, renal, hepatic, and hematological systems, among patients with severe- and critical-type COVID-19. This paper provides a clinical reference and a new strategy for the optimal treatment of COVID-19 worldwide.

ABSTRACT

Objective@#To understand the HIV infection status and related factors in men who have sex with men (MSM) in Tianjin during 2016-2018.@*Methods@#According to the sentinel surveillance protocol, continuous cross-sectional studies were conducted to collect the information about the awareness of AIDS, related behaviors, HIV infection, syphilis prevalence and HCV infection in the MSM in Tianjin with the annual sample seize of 400 between April and June during 2016-2018.@*Results@#From 2016 to 2018, a total of 1 200 MSM were surveyed. The condom use rate in anal sex was 45.4% (544/1 198) in the past 6 months. The HIV test rate in MSM recruited through network declined with year (trend χ2=42.742, P<0.001). The overall HIV infection rate was 3.3% (40/1 200). The HIV-1 infection rate was 2.6% (95%CI: 1.7%-3.5%). The overall prevalence rate of syphilis was 6.7% (80/1 200). The overall HCV infection rate was 0.8% (9/1 200). Results from multivariate logistic regression analysis showed that the risk factors associated with HIV infection in the MSM included divorced or widowed (compared with unmarried, aOR=7.137, 95%CI: 1.621-31.419) and syphilis positive group (compared with syphilis negative group, aOR=3.684, 95%CI: 1.520-8.932). The protective factors for HIV infection in the MSM included consistent use of condom in the past 6 months (compared with occasional use of condom, aOR=0.343, 95%CI: 0.126-0.932) and HIV test (compared with receiving no HIV test, aOR=0.314, 95%CI: 0.123-0.801).@*Conclusions@#The HIV infection rate in the MSM in Tianjin was high from 2016 to 2018. Syphilis prevalence status in MSM should not be neglected. The rate of consistent condom use in anal sex was low in the MSM. It is necessary to take effective measures to promote condom use and strengthen HIV test in MSM.

ABSTRACT

The newly reported HIV infected cases was collected, and HIV blood samples were detected to identify recent HIV infection in Tianjin during 2008-2015. Factors associated with HIV-1 infection were analyzed by the univariate and multivariate unconditional logistic regression. The recent HIV-1 infection proportion of homosexuals increased from 37.70% in 2008 to 83.68% in 2015. Those cases who aged ≤30 years (OR=1.53, 95%CI: 1.30-1.79), in han ethnic group (OR=1.40, 95%CI: 1.02-1.91), students (OR=1.79, 95%CI: 1.28-2.51) were more likely to be recent infected. The cases who had a high school education (OR=1.28, 95%CI: 1.05-1.56) or collage education (OR=1.23, 95%CI: 1.00-1.50) were more likely to be recent infected than those who had a primary school education. Compared with patients identified by hospitals, the recent HIV infections were more likely to be found through voluntary counseling and testing (VCT), STD outpatients, men who have sex with men (MSM) investigation and unpaid blood donors. Homosexual transmission has become the major route of HIV-1 recent infection in Tianjin.

ABSTRACT

Objective@#To study the survival time and influencing factors of HIV/AIDS cases who began receiving antiretroviral therapy (ART) from 2005 to 2015 in Tianjin.@*Methods@#Data related to HIV/AIDS cases that receiving ART between 2005 and 2015 in Tianjin, were collected from the Chinese HIV/AIDS Basic Information Management System. A retrospective cohort study was conducted to analyze data of collection. Life table was used to calculate the survival proportion and Cox proportion hazard regression model was used to analyze the factors associated to the time of survival.@*Results@#A total of 2 057 HIV/AIDS cases were involved, including 51 died from AIDS related disease, ending up with the survival rates of 1, 3, 5 and 10 years as 98.4%, 97.8%, 97.4% and 95.8%, respectively. Results from the multivariate Cox proportion hazard regression model showed that when comparing with the cases aged<30 years, aHR (95%CI) of the cases aged 30-39 years, 40-49 years, 50 years or above appeared as 4.506 (1.226-9.059), 5.944 (1.479-13.892) and 15.958 (5.309-27.206) respectively. When comparing with the cases having no loss of follow-up during ART process, the aHR of the cases having lost of follow-up during ART was 5.645 (95%CI: 3.124-10.200). When comparing with the cases diagnosed by other institutions, the aHR of the cases diagnosed by hospitals was 3.823 (95%CI: 1.423-10.274). When compared with the cases had no hepatitis B or hepatitis C before ART, aHR of the cases with hepatitis B or C prior to ART was 2.580 (95%CI:1.210-5.502). Compared with the cases receiving ART at Ⅰ/Ⅱ clinical stages, the aHR of the cases at Ⅲ/Ⅳ clinical stages was 3.947 (95%CI: 2.167-7.188). Compared with the cases with junior high school education or below, the aHR of the cases with high school education or above was 0.440 (95%CI: 0.238-0.810). Compared with the cases diagnosed before operation, aHR of the cases from special investigation and from counseling and testing (VCT) were 0.111 (0.027-0.456) and 0.182 (0.049-0.674) respectively.@*Conclusions@#The survival rate of HIV/AIDS cases that received ART was high in Tianjin. Risk factors related to the survival of cases would include: old age when started receiving ART, loss of follow-up during ART, diagnosed by hospitals, co-infected with hepatitis B or hepatitis C and receiving ART at Ⅲ/Ⅳ clinical stages. Meanwhile, protective factors related to the survival of cases would include: having high school or above education, diagnosis was made through other special programs or from VCT services.

ABSTRACT

Investigating the pathophysiological mechanisms underlying brain disorders is a priority if novel therapeutic strategies are to be developed. In vivo studies of animal models and in vitro studies of cell lines/primary cell cultures may provide useful tools to study certain aspects of brain disorders. However, discrepancies among these studies or unsuccessful translation from animal/cell studies to human/clinical studies often occur, because these models generally represent only some symptoms of a neuropsychiatric disorder rather than the complete disorder. Human brain slice cultures from postmortem tissue or resected tissue from operations have shown that, in vitro, neurons and glia can stay alive for long periods of time, while their morphological and physiological characteristics, and their ability to respond to experimental manipulations are maintained. Human brain slices can thus provide a close representation of neuronal networks in vivo, be a valuable tool for investigation of the basis of neuropsychiatric disorders, and provide a platform for the evaluation of novel pharmacological treatments of human brain diseases. A brain bank needs to provide the necessary infrastructure to bring together donors, hospitals, and researchers who want to investigate human brain slices in cultures of clinically and neuropathologically well-documented material.
