Comparative analysis of disease burden in Sichuan Province in 2010 and 2020 based on disability-adjusted life years / 上海预防医学

ObjectiveTo analyze the disease burden in Sichuan Province in 2010 and 2020， and to provide reference for disease prevention and control. MethodsMonitoring data on causes of death in Sichuan Province in 2010 and 2020 were collected. Disability-adjusted life years （DALY）， years of life lost （YLL） and years lived with disability （YLD） were calculated to assess the disease burden in Sichuan Province. ResultsIn 2020， DALY was 7.004 0 million years， among which YLL and YLD were 3.719 6 million and 3.284 4 million， respectively. Compared with 2010， the total DALY in 2020 increased by 8.27%， most of which came from the increase of YLL （16.66%）. In 2020， the standardized total DALY rate was 69.91‰， which decreased by 9.87% compared with 2010. Specifically， the rate decreased by 15.87% for females and 5.28% for males. In 2020， the burden of DALY disease in the elderly over 60 years old increased by 34.55% compared with 2010. The burden of infectious and maternal diseases decreased the most， and the standardized DALY rates of male and female in 2020 decreased by 47.03% and 55.50% compared with 2010， respectively. Injury was the next most important factor， which decreased by 32.97% in males and 26.92% in females. The standardized DALY rate of chronic diseases increased by 5.41% in males and decreased by 10.67% in females. In 2020， compared with 2010， the standardized DALY rate of males increased significantly in diabetes （82.02%）， nervous system and mental disorders （26.31%）， and cardiovascular and cerebrovascular diseases （19.86%）. Among women， significant increases were seen in diabetes mellitus （54.74%）， neurological and mental disorders （35.52%）， and musculoskeletal and connective tissue diseases （23.51%）. ConclusionThe overall disease burden in Sichuan Province shows a declining trend， mainly attributed to the decrease in infectious and maternal diseases and injuries. The disease burden among people over 60 years old has increased significantly， with the focus on chronic diseases such as diabetes， cardiovascular and cerebrovascular diseases， nervous system and mental disorders， and musculoskeletal and connective tissue diseases.

Short term effects of anti-reflux mucosectomy for proton pump inhibitor dependent gastroesophageal reflux disease / 中华消化内镜杂志

Clinical data of 26 patients with proton pump inhibitor dependent gastroesophageal reflux disease (GERD) who underwent anti-reflux mucosectomy (ARMS) in Nanjing Drum Tower Hospital from July 2017 to December 2020 were reviewed, and the GERD questionnaire (GERD-Q) score, the short-form reflux-qual (RQS) score, esophageal motility and 24 h esophageal pH parameters before and after ARMS were compared. With a median follow-up period of 18.4 months (6-27 months), 23 (88.5%) patients reported symptomatic improvement and 15 (57.7%) patients discontinued the use of proton pump inhibitors. After ARMS, the mean scores of GERD-Q (6.23 VS 13.19, P=0.004) and RQS (26.67 VS 10.98, P<0.001) were significantly improved, the mean DeMeester score (10.69 VS 53.15, P<0.001), the mean acid exposure time percentage (3.56% VS 9.92%, P<0.001) and the mean number of acid reflux episodes (36.9 VS 139.9, P=0.001) were lower, and the mean rest pressure at lower esophageal sphincter (LES) (25.19 mmHg VS 13.63 mmHg, P<0.001) and the mean distal contractile integral (1 819.15 mmHg·s·cm VS 1 007.67 mmHg·s·cm, P<0.001) were significantly increased compared with those before surgery. ARMS has significant short-term efficacy in the treatment of proton pump inhibitor dependent GERD, which can effectively improve reflux symptoms and life quality of patients, and strengthen the rest pressure of LES and peristalsis of the esophageal body.

OBJECTIVE@#To investigate the association of fetal cardiac structural abnormalities with chromosomal aneuploidies and copy number variations (CNVs) in amniocytes.@*METHODS@#328 pregnant women were subjected to fetal ultrasonography and chromosomal microarray analysis (CMA). Based on the fetal heart structure, the subjects were divided into normal (n=273) and abnormal groups (n=55). The detection rates of chromosomal aneuploidies and CNVs were compared between the two groups. Spearman method was used to assess the association between the results and fetal cardiac structural abnormalities.@*RESULTS@#The detection rates for chromosomal aneuploidies and CNVs in the abnormal group were significantly higher than that in the normal group (P< 0.05), and the incidence of fetal cardiac structural abnormalities was strongly associated with chromosomal aneuploidies and CNVs (P< 0.05).@*CONCLUSION@#Fetal chromosomal aneuploidies and CNVs are strongly associated with cardiac structural abnormalities.

Effect of adenovirus-mediated recombinant Buthus martensii Karsch chloride toxin artifact on human glioma U251 cells / 肿瘤研究与临床

Objective:To investigate the inhibitory effect of adenovirus-mediated recombinant Buthus martensii Karsch chloride toxin artifact (Ad-rBmK CTa) on human glioma U251 cells and its related mechanisms.Methods:Groups of 3 titer gradients of 3.5×10 9, 7.0×10 9 and 3.5×10 10 pfu/ml Ad-rBmK CTa were set up and applied to U251 cells for 24, 48 and 72 h, and a blank control group (no cells and Ad-rBmK CTa were added) and a negative control group (only U251 cells were added) were set up at the same time. The virus infection status was observed by laser confocal fluorescence microscopy. The cell proliferation in each group was detected by methyl thiazolyl tetrazolium (MTT) assay. The cell cycle and apoptosis in each group were detected by flow cytometry. The expressions of apoptosis-related proteins bax, bcl-2 and caspase-3 were detected by Western blot. Results:The infection rate of Ad-rBmK CTa was over 90% after acting on U251 cells for 24 h. As the titer of Ad-rBmK CTa increased, the proliferation inhibition rate of U251 cells treated for the same hours gradually increased (all P <0.01); with the extension of time, the proliferation inhibition rate of U251 cells treated with the same titer of Ad-rBmK CTa also gradually increased (all P < 0.01). After 7.0×10 9 pfu/ml Ad-rBmK CTa acted on U251 cells for 48 h, the proportion of cells in G 0/G 1 phase was (40.7±0.8)%, and cells in S phase and G 2 phase accounted for (35.7±0.6)% and (23.6±1.4)%, and the difference was statistically significant ( F = 225.119, P < 0.01). When 7.0×10 9 pfu/ml Ad-rBmK CTa acted on U251 cells for 24, 48 and 72 h, the apoptosis rates were (7.4±1.4)%, (19.2±1.7)% and (22.3±1.7)% ( F = 49.470, P < 0.01). After 7.0×10 9 pfu/ml Ad-rBmK CTa acted on U251 cells for 48 h, compared with the negative control group, the expressions of bax and caspase-3 proteins increased, and the expressions of bcl-2 decreased. Conclusions:Ad-rBmK CTa may act on the DNA damage-induced G 1/S detection site to arrest the cell cycle in G 0/G 1 phase, thus inhibiting the proliferation of U251 cells in vitro. However, its induction of apoptosis in U251 cells is not obvious. The mechanism may be related to the direct or indirect inhibition of chloride ion channels.

Clinical validation of eCura risk scoring system after endoscopic submucosal dissection for early gastric cancer / 中华消化内镜杂志

Objective:To verify the clinical applicability of " eCura system" , a scoring system for assessing the risk of lymph node metastasis after non-curative endoscopic submucosal dissection (ESD) for early gastric cancer (EGC).Methods:A retrospective analysis was performed on clinicopathological data of 155 patients with EGC, who underwent non-curative ESD confirmed by postoperative pathology in Drum Tower Hospital Affiliated to Medical School of Nanjing University from January 2012 to March 2018. According to the eCura scoring system, the 155 patients were divided to three groups: 100 cases in the low-risk group (0 to 1 point), 46 cases in the intermediate-risk group (2 to 4 points), and 9 cases in the high-risk group (5 to 7 points). Lymph node metastasis rates and prognosis of the three groups were observed and compared.Results:The follow-up time of the 155 patients was 25±15.0 months, of which median follow-up time was 25 months in the low-risk group, 23 months in the intermediate-risk group, and 34 months in the high-risk group. A total of 57 patients underwent additional surgery in the low-risk group, including 3 cases [5.26% (3/57)] of lymph node metastases; 29 patients underwent additional surgery in the intermediate-risk group, including 2 cases [6.90% (2/29)] of lymph node metastases; all 9 patients in the high-risk group underwent additional surgery and 4 cases had lymph node metastasis. Multivariate Logistic regression analysis showed that the risk of lymph node metastasis in the high-risk group was significantly higher than that in the low-risk group ( P=0.003, OR=14.499, 95% CI: 2.513-97.214), while the risk of lymph node metastasis in the intermediate-risk group was slightly higher than that in the low-risk group ( P=0.767, OR=1.326, 95% CI: 0.165-8.594). During follow-up, there was no metastasis or cancer-specific mortality in the low-risk group, and recurrence was found in 3 cases [6.98% (3/43)] of the 43 patients without additional surgery. Among the 17 patients in the intermediate-risk group, who did not undergo additional surgery, 1 case [5.88% (1/17)] had recurrence and 2 cases [11.76% (2/17)] had metastasis including 1 case [5.88% (1/17)] died of brain metastasis. There was no recurrence, metastasis or cancer-specific mortality in 29 patients in the intermediate-risk group, who underwent additional surgery during follow-up. And there was no recurrence, metastasis or cancer-specific mortality in the all 9 patients in the high-risk group received additional surgery after ESD during follow-up. Conclusion:The eCura scoring system could contribute to predict the lymph node metastasis risk in patients after non-curative ESD for EGC. The benefits of additional surgery are limited for low-risk patients, while for intermediate-risk and high-risk patients, additional surgery can effectively improve prognosis.

Analysis of blocking antibody and lymphocyte subsets in elderly patients with recurrent spontaneous abortion / 中国综合临床

Objective:To explore the relationship between blocking antibody and lymphocyte subsets in elderly patients (age≥35 years old) with recurrent spontaneous abortion(RSA).Methods:A retrospective case-control study was conducted on the patients with recurrent spontaneous abortion who met the inclusion criteria from October 2014 to September 2019 in the Reproductive Center of Women Health Center of Shanxi.They were divided into two groups according to their ages: 66 cases in RSA group and 334 cases in normal pregnant age group.The blocking antibody and lymphocyte subsets were detected by flow cytometry.Results:The negative rate of blocking antibody in elderly recurrent spontaneous abortion patients was 77.27% (51/66), which was not significantly different from that in normal gestational recurrent spontaneous abortion patients (83.53%(279/334)) ( P=0.221), but significantly higher than that in normal women (23.46%(42/179)) ( P=0.001). The blocking antibody′s blocking efficiency results showed that the CD3′s blocking efficiency of elderly recurrent spontaneous abortion patients (0.10 (-0.50, 0.60)) was significantly lower than that of normal women (0.60 (0.00, 1.30)), the difference was statistically( P=0.001). The CD8 blocking efficiency of elderly recurrent spontaneous abortion patients (0.00 (-0.60, 0.63)) was significantly lower than that of normal women (0.30 (0.00, 0.70)), the difference was statistically( P=0.016). Lymphocyte subsets showed that the CD8 + T cell ratio in elderly recurrent spontaneous abortion patients (26.93±7.25) was significantly lower than that in normal gestational recurrent spontaneous abortion patients (29.22±7.29), the difference was statistically significant ( P=0.020). The CD4 + /CD8 + ratio in elderly recurrent spontaneous abortion patients (1.64±0.99) was significantly higher than that in normal gestational age recurrent spontaneous abortion patients (1.37±0.50), the difference was statistically significant ( P=0.030). The ratio of natural killer cells in elderly recurrent spontaneous abortion patients (16.13±7.10) was significantly higher than that in normal women (14.04±2.35), the difference was statistically significant ( P=0.022), and higher than that in normal gestational age recurrent spontaneous abortion women (15.57±7.02). Conclusion:There were differences in lymphocyte subsets between elderly RSA patients and normal pregnant women, and the increase of natural killer cell ratio may be an important factor in the occurrence of RSA, especially in elderly RSA patients.

Study on the minimum inhibitory concentration of β-lactam and β-lactam resistance molecular mechanism of Haemophilus influenzae isolates from neonates / 中国小儿急救医学

Objective:To study the changes of β-lactam resistance of Haemophilus influenzae (Hi) strain isolated from neonatal lower respiratory tract and the molecular mechanism of β-lactam resistance.Methods:Nineteen Hi strains isolated from neonatal lower respiratory tract infection in the previous multicenter prospective epidemiological study were re-identified, and the P6, fucK and Cap genes were detected by PCR.The minimum inhibitory concentration(MIC) of ampicillin, amoxicillin clavulanic acid and cefuroxime were detected by microdilution method, and tem-1 gene, rob-1 gene and ftsI gene were sequenced and analyzed.Results:(1) Nineteen strains of Hi were confirmed to be capsule-free type by P6 gene, fucK gene and cap gene, which was non-typeable Haemophilus influenzae(NTHi). (2)Compared with 2003-2004, the MIC values of ampicillin, amoxicillin clavulanic acid and cefuroxime of NTHi isolated from the lower respiratory tract of the newborn from 2013-2014 were significantly higher( P<0.05). (3)The rates of β-lactamase producing strains during 2003-2004 and 2013-2014 were 33.33% (3/9) and 30.00% (3/10), respectively.There was no significant difference between them during 10 years ( P>0.05). The detection of the β-lactamase gene showed that the β-lactamase of the all six strains were of the tem-1 type, and the rob-1 type was not detected.(4)Only one gBLNAR strain ( n=9) was found during 2003~2004, and gBLNAR 1, gBLNAI 3, gBLPAR 3, gBLPACR 1 ( n=10)appeared during 2013~2014.(5)There were 11 amino acid substitution patterns in ftsI gene during 2013~2014, but only five amino acid substitution patterns in 2003~2004.The mutation rate of the S357N, S385T, N526K and T532S of ftsI gene significantly increased during the past ten years ( P<0.05). One strain of gBLNAR/gBLNACR resistant to ampicillin, amoxicillin clavulanic acid and cefuroxime isolated in 2014 showed D350N, S357N, M377I, S385T, L389F, A502T and N526K variation at the same time. Conclusion:Neonatal patients with lower respiratory tract NTHi infection may rapidly face the severe challenge of multiple drug resistance of β-lactam antibiotics.

Comparative analysis of constitutes and metabolites for traditional Chinese medicine using IDA and SWATH data acquisition modes on LC-Q-TOF MS / 药物分析学报

Identification of components and metabolites of traditional Chinese medicines (TCMs) employing liquid chromatography-quadrupole time-of-flight mass spectrometry (LC-Q-TOF MS) techniques with information-dependent acquisition (IDA) approaches is increasingly frequent. A current drawback of IDA-MS is that the complexity of a sample might prevent important compounds from being triggered in IDA settings. Sequential window acquisition of all theoretical fragment-ion spectra (SWATH) is a data-independent acquisition (DIA) method where the instrument deterministically fragments all precursor ions within the predefined m/z range in a systematic and unbiased fashion. Herein, the superiority of SWATH on the detection of TCMs' components was firstly investigated by comparing the detection ef-ficiency of SWATH-MS and IDA-MS data acquisition modes, and sanguisorbin extract was used as a mode TCM. After optimizing the setting parameters of SWATH, rolling collision energy (CE) and variable Q1 isolation windows were found to be more efficient for sanguisorbin identification than the fixed CE and fixed Q1 isolation window. More importantly, the qualitative efficiency of SWATH-MS on sanguisorbins was found significantly higher than that of IDA-MS data acquisition. In IDA mode, 18 kinds of sangui-sorbins were detected in sanguisorbin extract. A total of 47 sanguisorbins were detected when SWATH-MS was used under rolling CE and flexible Q1 isolation window modes. Besides, 26 metabolites of sangui-sorbins were identified in rat plasma, and their metabolic pathways could be deduced as decarbonylation, oxidization, reduction, methylation, and glucuronidation according to their fragmental ions acquired in SWATH-MS mode. Thus, SWATH-MS data acquisition could provide more comprehensive information for the component and metabolite identification for TCMs than IDA-MS.

Clinicopathologic characteristics and relevance of main and minor lesions of synchronous multiple early gastric cancer and gastric high grade intraepithelial neoplasia / 中华消化内镜杂志

Objective To investigate the clinicopathologic characteristics and relevance of main and minor lesions of synchronous multiple early gastric cancers ( SMEGC) and gastric high grade intraepithelial neoplasia ( GHGIN) . Methods Thirty-two patients with SMEGC or/and GHGIN who were diagnosed and treated with endoscopic submucosal dissection in Nanjing Drum Tower Hospital from July 2012 to September 2016 were enrolled in this study. Their clinicopathologic characteristics were summed up, and the correlation between main and minor lesions on the size, location, endoscopic classification, pathologic type, invasion depth and vascular invasion were analyzed. Results Among the 32 patients, with mean age of 66. 19±7. 46 years, 90. 62％(29/32) were male, 17 cases (53. 3％) had family history of gastric cancer, 25 (78. 13％) had smoking history, and 22 ( 68. 75％) were alcohol users. There were 30 cases ( 93. 75％) and 31 cases ( 96. 88％) with mucosal atrophy and intestinal metaplasia, respectively. The size of main and minor lesions showed a positive correlation (r=0. 4167, P=0. 018). The endoscopic classification of major and minor lesions had no statistical significant consistency ( P=0. 314 ) , but the pathologic type and invasion depth between major and minor lesions demonstrated a moderate significant positive correlation ( P<0. 05 ) . The comparison of location between the main and minor lesions did not show correlation. However, it showed a significant correlation between major lesion which on the upper 1/3 of stomach and minor lesion on the lower 1/3 of stomach ( r=0. 463,P=0. 003) . Further more, when the main lesion was at posterior gastric wall, the minor lesions on lesser curvature were increased, which showed a positive correlation( r=0. 417,P=0. 009) . Conclusion Old-age male with long-term smoking and alcohol history whose lesions combined with surrounding mucosa merger atrophy and intestinal metaplasia are considered as a high risk group in patients with SMEGC or/and GHGIN. Therefore, clinicians must keep high vigilant and make carefully observations on this group of patients during endoscopic examination, and consider the correlation between main and minor lesions to avoid misdiagnosis.
