Abstract
Objective: To analyze the trend of liver cancer morbidity and mortality among residents with household registration in certain District, 2017 to 2019. Methods: The crude morbidity and mortality rate of males and females in the whole population were calculated by using the relevant data from the certain District Cancer Registry and Report System and the Cause of Death Surveillance System. The standardized morbidity and mortality rate were calculated according to the age structure of 2000 National Demographic Census and Segi's world population, respectively. Trend in liver cancer morbidity and mortality were evaluated using percent change (PC), annual percentage change, and case-number-weighted annual percent change. Age-specific rates were used to analyze the epidemic trend of liver cancer with age. Results: The crude morbidity rate of liver cancer in the whole population (male and female) of the certain district from 2017 to 2019 were 18.86/100 000, 26.05/100 000 and 11.90/100 000 respectively, and the crude mortality rates were 21.20/100 000, 29.29/100 000 and 13.38/100 000 respectively. The crude morbidity and mortality rate of liver cancer among male showed a downward trend (PC=-16.77% and -20.15% respectively). The crude morbidity and mortality rate of liver cancer among female showed inconsistent changes; however, the crude morbidity rate showed a downward trend, and the crude mortality rate first increased and then decreased (PC=-19.42% and -0.30% respectively). Liver cancer morbidity and mortality rate in male after the age of 30 were increased with age. The two key points of accelerated growth were around the age of 65 and 75, and the peak of morbidity (130.78/100 000) and mortality (201.96/100 000) were after the age of 80. The morbidity and mortality rate were significantly lower in female than those of male aged 60; however, after the age of 65, the morbidity rate was increased rapidly and gradually approached as that of male. After the age of 80 (the peak morbidity and mortality were 104.40/100,000 and 132.87/100,000, respectively), male were about twice as high as those female aged between 75 and 79. Conclusion: Morbidity and mortality rate of liver cancer in the certain District showed an overall downward trend from 2017 to 2019, but it increased with age, and the disease burden was relatively high among the elderly population. Liver cancer mostly occurred in male, so the prevention and control of liver cancer epidemics in middle-aged and elderly should be actively monitored.

Abstract
To investigate the feasibility and safety of total laparoscopic cardia function preserving gastrectomy for gastric carcinoma. Clinical data of 10 patients undergoing total laparoscopic cardia function preserving gastrectomy for gastric carcinoma from November 2020 to December 2021 were retrospectively collected. There were 7 males and 3 females. The mean age was (66.1±12.9) years (ranged from 38 to 86 years). All of the 10 patients were successfully performed total laparoscopic cardia function preserving gastrectomy without conversion to laparotomy. The time of digestive tract reconstruction was (24.8±3.3) min (20-30 min), and the intraoperative blood loss was (35±24) ml(20-100 ml). The time of postoperative exhaust was (2.5±0.9) days(2-3 d), the time of postoperative liquid diet was (2.25±0.87) days(2-3 d), postoperative hospital stay was (9.5±2.1) days(6-13 d). No surgical complications such as bleeding, anastomotic fistula or anastomotic stenosis occurred. Postoperative pathology showed that the proximal and distal margins of resected specimens were negative. Patients were followed up for 2 to 15 months, respectively. No death or tumor recurrence and metastasis occurred during the follow-up period. There were no symptoms of reflux after operation. Compared with total gastrectomy and proximal gastrectomy, total laparoscopic cardia function preserving gastrectomy can theoretically reduce the incidence of reflux esophagitis. We used manual suture method for digestive tract reconstruction, which can reduce the application of 2-3 stapling studs and reduce the cost of surgical materials. Compared with subtotal gastrectomy, total laparoscopic cardia function preserving gastrectomy has the advantages of more thorough lymph node dissection, with little residual gastric tissue; therefore, the blood supply is relatively better. The incidence of reflux esophagitis of total laparoscopic cardia function preserving gastrectomy for gastric cancer may was lower than total gastrectomy.

Abstract
Using a sample of about 10^{10} J/ψ events collected at a center-of-mass energy sqrt[s]=3.097 GeV with the BESIII detector, the electromagnetic Dalitz decays J/ψ→e^{+}e^{-}π^{+}π^{-}η^{'}, with η^{'}→γπ^{+}π^{-} and η^{'}→π^{+}π^{-}η, have been studied. The decay J/ψ→e^{+}e^{-}X(1835) is observed with a significance of 15σ, and also an e^{+}e^{-} invariant-mass dependent transition form factor of J/ψ→e^{+}e^{-}X(1835) is presented for the first time. The intermediate states X(2120) and X(2370) are also observed in the π^{+}π^{-}η^{'} invariant-mass spectrum with significances of 5.3σ and 7.3σ. The corresponding product branching fractions for J/ψ→e^{+}e^{-}X, X→π^{+}π^{-}η^{'} [X=X(1835), X(2120), and X(2370)] are reported.

Abstract
Objective: To compare and analyze the clinical curative effect and safety of chemoembolization with drug-loaded microspheres of different particle sizes (D-TACE) for the treatment of hepatocellular carcinoma. Methods: Clinical data of 281 cases with hepatocellular carcinoma treated with drug-loaded microspheres-transarterial chemoembolization (TACE) were retrospectively analyzed. According to the different particle sizes of drug-loaded microspheres, they were divided into 100~300 µm (small particle size) and 300~500 µm (large particle size) group. Tumor response rate and complication conditions at 1, 3, and 6 months after chemoembolization were compared. The overall survival time of the two groups were analyzed. Quantitative data conformed to normal distribution and homogeneity of variance were compared using t-test, while other with Wilcoxon signed rank-sum test. Qualitative data were compared using χ2 test. Kaplan-Meier method was used for survival analysis, and the differences in survival were analyzed using Log-rank test. P<0.05 was considered as statistically significant. Survival curves and histograms were drawn using GraphPad Prism9.1 software. Results: The complete remission rates at 1, 3 and 6 months after surgery in the small and large particle size groups were 31.25%, 30.15%, and 42.45% and 18.25%, 15.79% and 24.74%, respectively, and the differences were statistically significant between groups (P1 month=0.012, P3 month=0.009, P6 month=0.008, P<0.05). The objective remission rates at 1, 3 and 6 months after surgery in the small and large particle size groups were 88.19%, 76.99%, and 70.75% and 81.02%, 72.81% and 53.60%, respectively. Six months after surgery, the small particle size group (objective response rate = 70.75%) was significantly higher than the large particle size group (objective response rate=53.6%, P=0.012). The disease control rates of the small particle size group were 95.14%, 83.33%, and 74.53%, while large particle size group were 91.24%, 81.58%, and 64.95%, respectively, with no statistically significant difference between the two groups. However, the incidence of postoperative biliary tumors (6.20%) was significantly higher in the small-size than large-size group (0.70%), and the difference was statistically significant (P<0.05, P=0.03). There were no statistically significant differences between other adverse events such as post-embolization syndrome, liver abscess, and myelosuppression. The median survival time of the small and large particle size groups was 31.8 months and 20.5 months, respectively, but the difference was not statistically significant (P=0.182). Conclusions: In the treatment of hepatocellular carcinoma with D-TACE, the short-term curative effect of the small particle size group was better than large particle size group, but the incidence of biliary tumors was high, and D-TACE of different particle sizes had no significant effect on long-term survival.

Abstract
Pyoderma gangrenosum (PG) is a rare chronic inflammatory non-infectious skin dermatosis, and there is no clear treatment guideline for this disease at home and abroad. There are a variety of clinical treatment methods for PG, including local therapy and systemic application of glucocorticoids, immunosuppressants, intravenous immuno- globulin, and biologics. Glucocorticoids are the first-line drugs commonly used in clinical practice, and immunosuppressants can be used alone or in combination with glucocorticoids. In recent years, more and more evidence has shown that biologics are a new trend in the treatment of PG, mainly including tumor necrosis factor α inhibitors, interleukin-1 (IL-1) inhibitors, IL-12/23 inhibitors, IL-17 inhibitors, rituximab, and small molecular inhibitors. This article summarizes the current status and latest progress in the treatment of PG, hoping to provide clinicians with ideas for the treatment of PG.

Abstract
There is a potential risk for severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) spread through human contact with seafood and the inanimate materials contaminated by the virus. In this study, we examined the stability of the virus in artificial seawater (ASW) and on the surface of selected materials. SARS‐CoV‐2 (3.75 log10 TCID50) in ASW at 22℃ maintained infectious about 3 days and at 4℃ the virus survived more than 7 days. It should be noticed that viable virus at high titer (5.50 log10 TCID50) may survive more than 20 days in ASW at 4℃ and for 7 days at 22℃. SARS‐CoV‐2 on stainless steel and plastic bag maintained infectious for 3 days, and on nonwoven fabric for 1 day at 22℃. In addition, the virus remained infectious for 9 days on stainless steel and non‐woven fabric, and on plastic bag for 12 days at 4℃. It is important to highlight the role of inanimate material surfaces as a source of infection and the necessity for surface decontamination and disinfection.

Abstract
Objective: To explore accurate prenatal diagnosis, full-coverage graded counseling and follow-up for the fetus with cardiac birth defects (CBD). Methods: CBD fetus diagnosed prenatal by echocardiography from January 2018 to December 2020 in Guangdong Provincial People's Hospital were enrolled. Fetal CBD was graded (Ⅰ-Ⅵ) according to prognosis and possible operation time after birth, and the classification criteria and common diseases included were proposed. After the prenatal grading counseling, the outcome of the fetus was followed-up. The induced labor rate, live birth rate, prenatal and postnatal ultrasound diagnosis coincidence rate and other indicators were calculated. The disease composition ratio, prognosis of fetus with different grades and the outcome of integrated treatment were analyzed. Results: The detection rate of fetal CBD was up to 16.2% (1 971/12 188), 30 cases of which were excluded. A total of 1 941 cases were included in this study, including 196 cases (10.1%) of gradeⅠ, 433 cases (22.3%) of gradeⅡ, 615 cases (31.7%) of grade Ⅲ, 261 cases (13.4%) of grade Ⅳ, 388 cases (20.0%) of gradeⅤ, 48 cases (2.5%) of grade Ⅵ. Grade Ⅱ and gradeⅢ (the operation time was within 1 year after birth) accounted for 54.0% (1 048/1 941). The distribution of some diseases in different grades had obvious proportion advantage, which was representative. Among 1 747 CBD fetus, 736 cases (induced labor rate 42.1%) chose to terminate pregnancy due to CBD. Of the 1 010 live births, 975 cases (96.5%) had the same prenatal and postnatal diagnosis, 3 cases were missed diagnosis and 32 cases were misdiagnosed. The diagnostic accuracy of live births with severe and complex congenital heart disease was 383 out of 389 (98.5%). A total of 258 cases have received surgery or intervention. The age at the time of surgery or intervention was different among grades(χ²=47.3,P<0.001). With the improvement of prognosis from gradeⅠ to Ⅴ, the live birth rate increased and the induced labor rate decreased accordingly; the difference between grades was significant(χ²=623.6,P<0.001). Conclusions: Prenatal diagnosis and graded counseling is important in the integrated model. Fetal CBD grading could refine post-natal treatment strategies, guide delivery decisions and become an evaluation standard.

Observation of the Singly Cabibbo Suppressed Decay Λ_{c}^{+}→nπ^{+}. PHYSICAL REVIEW LETTERS 2022; 128:142001.

Abstract
The singly Cabibbo-suppressed decay Λ_{c}^{+}→nπ^{+} is observed for the first time with a statistical significance of 7.3σ by using 3.9 fb^{-1} of e^{+}e^{-} collision data collected at center-of-mass energies between 4.612 and 4.699 GeV with the BESIII detector at BEPCII. The branching fraction of Λ_{c}^{+}→nπ^{+} is measured to be (6.6±1.2_{stat}±0.4_{syst})×10^{-4}. By taking the upper limit of branching fractions of Λ_{c}^{+}→pπ^{0} from the Belle experiment, the ratio of branching fractions between Λ_{c}^{+}→nπ^{+} and Λ_{c}^{+}→pπ^{0} is calculated to be larger than 7.2 at the 90% confidence level, which disagrees with most predictions of the available phenomenological models. In addition, the branching fractions of the Cabibbo-favored decays Λ_{c}^{+}→Λπ^{+} and Λ_{c}^{+}→Σ^{0}π^{+} are measured to be (1.31±0.08_{stat}±0.05_{syst})×10^{-2} and (1.22±0.08_{stat}±0.07_{syst})×10^{-2}, respectively, which are consistent with previous results.

Abstract
In recent years, ozone pollution has been growing increasingly serious in the urban areas of China. Volatile organic compounds (VOCs) are important precursors of O3 formation, which is of great significance to studying the main characteristics and sources of VOCs for controlling O3 pollution. In this study, we conducted online VOCs observation in Zibo City from May to September in 2019, monitoring 56 species in total. During the observation, the over-standard rate of ozone was up to 67.8%, the average of ρ(VOCs) was 140.71 μg·m-3, and the concentration of VOCs in the ozone over standard days was 1.04 times that on the non-standard days. The rank of VOC classes was aromatic hydrocarbons>alkanes>alkenes>alkynes. Among them, 1,3,5-tritoluene, o-ethyltoluene, 1-butene, and n-hexane achieved high emission in the exceeding O3 and non-exceeding days. Aromatic hydrocarbon and alkenes contributed more to the potential of ozone formation. According to the PMF source analysis results, VOCs sources in the urban area mainly included motor vehicle sources, fixed combustion sources, solvent sources, process sources, and natural plant sources, among which motor vehicle sources were the most important source of VOCs in the urban area. In addition, motor vehicle sources accounted for 32.3%, and fixed combustion sources accounted for 24.2% on days when ozone exceeded the standard, which increased by 3.3% and 6.9%, respectively, compared with those on days when ozone did not exceed the standard. However, the proportion of solvent sources and process sources decreased by 5.1% when ozone exceeded the standard compared with that on a non-standard day.

Abstract
Objective: To analyze the diversity differences of gut microbiota between school-aged obese children and normal-weight children and identify the characteristic flora in obese children to provide some evidence for the subsequent study of the following study-related mechanisms and the prevention and treatment of obesity in school-aged children. Methods: This study was based on a cohort established in a primary school in Jiading district, Shanghai, 2016. Sixty-three children, including 43 boys and 20 girls, who were obese during the three years from 2016 to 2018, were enrolled in the obesity group. Among children who were average weight for three years, a total of 63 were selected as the control group, with matching with the obese ones in a 1 to 1 way according to age, sex and class. The primary characteristics, diet status, breastfeeding, and other information of children were collected by questionnaire. Fecal samples of participants in both groups were collected, and 16S rDNA sequencing was performed. Operable taxon units clustering according to 97% similarity and species annotation were based on the quality-optimized sequences. The difference in the diversity and genius of gut microbiota among children in the obesity and control groups were analyzed. The α diversity indices, including Ace, Chao1, Shannon, and Simpson index, were calculated. The β diversity was presented based on unweighted Unifrac distance and weighted Unifrac space by principal coordinate analysis. The differences in β diversity between the two groups were compared by similarity analysis (ANOSIM).The differences in genus distribution between the two groups were selected by STAMP software. The association of obesity with the α diversity and genus with significant differences were analyzed by the generalized linear model (GLM). Results: The Ace and Chao1 index in the obesity group was significantly lower than those in the control group (The P values were 0.026 and 0.039, respectively). There was no significant difference in Shannon and Simpson index between the two groups (The P values were 0.879 and 0.922, respectively). The results of ANOSIM showed differences in gut microbiota between the two groups (R>0), but the group contribution was not significant (unweighted Unifrac distance: R=0.006, P=0.223; weighted Unifrac distance: R=0.010, P=0.134). Among the obese group, the relative abundance of Prevotella and Sarcina was highest in the endemic genus. The STAMP results showed that the relative lots of 15 genera were significantly different between the two groups (P<0.05). The results of GLM showed that, compared with the control group, the obesity group had a lower level of the relative abundance in Akkermansia muciniphila, while a higher level in Coprococcus_3, Ruminococcus, Agathobacter and Collinsella. After stratification by sex, the Chao1 index was also lower in the obese boys than that in the normal-weight boys. However, the obese girls only had a higher level in Coprococcus_3 than the ordinary weight girls. Conclusions: Compared with children with average weight, obese children had lower α diversity of gut microbiota and lower relative abundance of dominant probiotics but had a higher relative lot of genus associated with metabolic disorders, inflammation promotion, and metabolism rate reduction.

Abstract
Malignant pleural mesothelioma (MPM) is a kind of invasive malignant tumor originated from pleural tissue. The incidence of MPM is not high in the population, but the prognosis is very poor. The median survival time is only about 12 months. Pemetrexed combined with platinum is the first-line chemotherapy regimen recommended by the current guidelines. The use of bevacizumab will further prolong the survival of chemotherapy. Once resistance happened, no anti-tumor treatment has been confirmed to achieve survival benefits. Therefore, there is no recommended standard second-line MPM regimen in international and domestic guidelines, including National Comprehensive Cancer Network (NCCN) guidelines. Vinorelbine, gemcitabine and other monotherapy regimens are commonly used in clinical practice, but the median progression free survival (PFS) is only about 3 months. Immune checkpoint inhibitors (ICIS) have been proved to have a significant inhibitory effect on tumor growth in a variety of malignant tumors, and their efficacy is related to the expression of programmed death-ligand 1(PD-L1). In unresectable MPM, programmed death 1 (PD-1)/PD-L1 inhibitors have been used in a series of clinical studies in the first-line, second-line and above treatment. Some of the results have been cited and recommended by international guidelines, but the overall efficacy improvement is still limited. This review summarizes the latest clinical studies and researches in the field of MPM treatment and predicts the directions and prospect of improving the therapeutic effect in the future.

Abstract
In this study, we obtained monitoring data of O3 and its precursors (NOx, VOCs, and CO), as well as meteorological data (temperature, relative humidity, wind speed, and visibility), in 2019 to analyze the characteristics of O3 pollution and the influencing factors in urban and suburban areas. The results showed that the O3 episodes accounted for 25.8% of the whole observation period, mostly occurring from May to September. The concentration of NOx in urban areas was higher than that in suburban areas, whereas the concentrations of O3 and VOCs were lower. The hourly rate of variation in each pollutant had obvious seasonal characteristics; for example, the time of O3 rise and precursor decline in autumn and winter was approximately 1 h later than that in summer, and the peak period of O3 generation and accumulation was shortened. The increase rate in O3 in urban areas was higher than that in suburban areas. Correlation analysis and partial correlation analysis were used to study the relationship between O3 and its influencing factors. The results showed that O3 was negatively correlated with precursors and relative humidity and positively correlated with visibility, temperature, and wind speed, and these factors interacted with each other. According to the multivariate linear regression analysis, the main controlling factors in urban areas were relative humidity, NOx, visibility, and VOCs, whereas in suburban areas they were relative humidity, temperature, NOx, and VOCs.

Abstract
Using a data sample corresponding to an integrated luminosity of 2.93 fb^{-1} collected at a center-of-mass energy sqrt[s]=3.773 GeV by the BESIII detector, the decay D^{0}→ωϕ is observed for the first time. The branching fraction is measured to be (6.48±0.96±0.40)×10^{-4} with a significance of 6.3σ, where the first and second uncertainties are statistical and systematic, respectively. An angular analysis reveals that the ϕ and ω mesons from the D^{0}→ωϕ decay are transversely polarized. The 95% confidence level upper limit on longitudinal polarization fraction is set to be less than 0.24, which is inconsistent with current theoretical expectations and challenges our understanding of the underlying dynamics in charm meson decays.

Abstract
Objective: To examine the clinical effect of minimally invasive duodenum preserving pancreatic head resection(DPPHR) for benign and pre-malignant lesions of pancreatic head. Methods: The clinical data of patients with diagnosis of benign or pre-malignant pancreatic head tumor were retrospectively collected and analyzed,all of them underwent laparoscopic or robotic DPPHR between October 2015 and September 2021 at Division of Gastrointestinal and Pancreatic surgery,Zhejiang Provincial People's Hospital. Thirty-three patients were enrolled with 10 males and 23 females. The age(M(IQR)) was 54(32) years old(range: 11 to 77 years old) with body mass index of 21.9(2.9)kg/m2(range: 18.1 to 30.1 kg/m2). The presenting symptoms included abdominal pain(n=12), Whipple triad(n=2), and asymptomatic(n=19), among them there were 7 patients with hypertension and 1 patient with diabetes mellitus. There were 19 patients diagnosed as American Society of Anesthesiologists class Ⅰ and 14 patient as class Ⅱ. The student t test,U test, χ2 test or Fisher exact test was used to compare continuous data or categorized data,respectively. All the perioperative data and metabolic morbidity were analyzed and experiences on minimally invasive DPPHR was concluded. Results: Fourteen patients underwent laparoscopic DPPHR,while the rest of 19 patients received robotic DPPHR. Indocyanine green fluorescence imaging was used in 19 patients to guide operation. Five patients were performed pancreatico-gastrostomy and the rest 28 patients underwent pancreaticojejunostomy. Pathological outcomes confirmed 9 solid pseudo-papillary neoplasms, 9 intraductal papillary mucinous neoplasms, 7 serous cystic neoplasms, 6 pancreatic neuroendocrine tumors, 1 mucous cystic neoplasm, 1 chronic pancreatitis. The operative time was (309.4±50.3) minutes(range:180 to 420 minutes),and the blood loss was (97.9±48.3)ml(range:20 to 200 ml). Eighteen patients suffered from postoperative complications,including 3 patients experienced severe complications(Clavien-Dindo Grade ≥Ⅲ). Pancreatic fistula occurred in 16 patients,including 8 patients with biochemical leak,7 patients with grade B pancreatic fistula and 1 patient with grade C pancreatic fistula. No one suffered from the duodenal necrosis and none perioperative death was occurred. The length of hospital stay was 14(7) days (range:6 to 87 days). The follow-up was 22.6(24.5)months(range:2 to 74 months). None suffered from recurrence or metastasis. During the follow-up,all the patients were free of refractory cholangitis. Moreover,in the term of endocrine dysfunction,no postoperative new onset of diabetes mellitus were observed in the long-term follow-up. However,in the view of exocrine insufficiency,pancreatic exocrine insufficiency and non-alcoholic fatty liver disease (NAFLD) was complicated in 2 and 1 patient,respectively,with the supplement of pancreatic enzyme,steatorrhea and weight loss relieved,but NAFLD was awaited to be seen. Conclusions: Minimally invasive DPPHR is feasible and safe for benign or pre-malignant lesions of pancreatic head. Moreover,it is oncological equivalent to pancreaticoduodenectomy with preservation of metabolic function without refractory cholangitis.

Abstract
Objective: To investigate the effect of apoptosis-associated protein kinase-like 1 (DAPL1) hypomethylation on prognosis of lung cancer patients with epidermal growth factor receptor gene exon 19 deletion (EGFR Del19) mutation. Methods: The clinicopathological data of lung cancer patients in databases of genomic data sharing (GDC) TCGA lung adenocarcinoma, TCGA lung adenocarcinoma, and TCGA lung cancer were collected to analyze the effect of DAPL1 methylation level on the prognosis of patients with EGFR Del19 mutation. Linear regression model was used for correlation analysis, Kaplan-Meier method was used to draw the survival curve, and the difference of survival curve between the two groups was tested by Log rank. Results: In GDC TCGA lung adenocarcinoma, TCGA lung adenocarcinoma and TCGA lung cancer databases, the 5-year survival rates of lung cancer patients with high DAPL1 expression (31.9%, 27.5% and 33.0%, respectively) were higher than those with low DAPL1 expression (11.0%, 11.6% and 13.8%, respectively). The differences were statistically significant (P=0.006, 0.028 and 0.025, respectively). The median expression levels of DAPL1 in patients with EGFR Del19 mutation (12.8, 2.75 and 2.9, respectively) were higher than those in patients with other EGFR mutations (11.6, 1.75 and 1.8, respectively, P<0.05). In TCGA lung adenocarcinoma and TCGA lung cancer database, the 5-year survival rate of lung cancer patients with lower DAPL1 methylation levels (22.4% and 16.4%, respectively) were higher than those of lung cancer patients with higher DAPL1 methylation levels (15.1% and 14.2%, respectively), with statistical significance (P<0.05). The expression level of DAPL1 was positively correlated with the EGFR mutant subtype (r=0.909, P<0.05), and negatively correlated with DNA methylation (r=-0.891, P<0.05). The expression of DAPL1 in lung cancer patients was regulated by DNA methylation, which affected the prognosis of lung cancer patients. Conclusion: High DAPL1 expression, or hypomethylation, is associated with lung cancer EGFR Del19 mutation subtype, and DAPL1 hypomethylated lung cancer patients have longer overall survival.

Abstract
Objective: To develop a prototype artificial intelligence image recognition system for detecting dental caries, especially those without cavities, in children. Methods: Seven hundred and twelve intraoral photos, which were taken by dental professionals using a digital camera from October 2013 to June 2020 in the Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology, were collected from the children who received dental treatment under general anesthesia. The well-documented post-treatment electronic dental record of each child was identified as label standard to determine whether the teeth were carious and the type of caries types such as caries that had become cavities (caries with cavities), pit and fissure caries that had not become cavities (pit and fissure caries) and proximal caries which the marginal ridge enamel had not been destroyed (proximal caries). The various teeth and caries types were labeled by pediatric dentists using VoTT software (Windows 2.1.0, Microsoft, U S A). There were five labeled groups: pit and fissure caries, approximal caries, non-carious approximal surfaces, caries with cavities and teeth without caries (including intact fillings). Each group was randomly divided into training dataset, validation dataset and test dataset at a ratio of 6.4∶1.6∶2.0 by using random number table. After using the labeled training dataset for deep learning training, a deep learning-based artificial intelligence (AI) image recognition system for detecting dental caries was established, with the caries probability greater than 50.0% as the criterion for determining caries. Sensitivity and accuracy were used as indicators of recognition specificity. Results: Seven hundred and twelve single-jaw intraoral photographs were segmented and annotated into 953 pit and fissure caries, 1 002 approximal caries, 3 008 caries with cavities, 3 189 teeth without caries and 862 non-carious approximal surfaces, totaly 9 014 labels. The sensitivities and specificities of the test set were 96.0% and 97.0% for caries with cavities, 95.8% and 99.0% for pit and fissure caries and 88.1% and 97.1% for approximal caries. Conclusions: The current AI system developed based on deep learning of the intra-oral photos in the present study showed the ability to detect dental caries. Furthermore, the AI system could accurately verify different types of dental caries such as caries with cavities, pit and fissure caries and proximal caries.

Abstract
Using a dataset of 6.32 fb^{-1} of e^{+}e^{-} annihilation data collected with the BESIII detector at center-of-mass energies between 4178 and 4226 MeV, we have measured the absolute branching fraction of the leptonic decay D_{s}^{+}→τ^{+}ν_{τ} via τ^{+}→e^{+}ν_{e}ν[over ¯]_{τ}, and find B_{D_{s}^{+}→τ^{+}ν_{τ}}=(5.27±0.10±0.12)×10^{-2}, where the first uncertainty is statistical and the second is systematic. The precision is improved by a factor of 2 compared to the previous best measurement. Combining with f_{D_{s}^{+}} from lattice quantum chromodynamics calculations or the |V_{cs}| from the CKMfitter group, we extract |V_{cs}|=0.978±0.009±0.012 and f_{D_{s}^{+}}=(251.1±2.4±3.0) MeV, respectively. Combining our result with the world averages of B_{D_{s}^{+}→τ^{+}ν_{τ}} and B_{D_{s}^{+}→μ^{+}ν_{μ}}, we obtain the ratio of the branching fractions B_{D_{s}^{+}→τ^{+}ν_{τ}}/B_{D_{s}^{+}→μ^{+}ν_{μ}}=9.72±0.37, which is consistent with the standard model prediction of lepton flavor universality.

Abstract
Objective: To investigate the effect of neuregulin-1(NRG-1) on cardiac glucose metabolism in Sprague Dawley (SD) rats with experimental myocardial infarction (MI). Methods: Adult male SD rats were randomly divided into three groups: the sham-operated group, MI group, and MI+NRG1 group. The rat MI model was established via ligation of the left anterior descending coronary artery. Two weeks after operation, echocardiography was performed, MI rats with left ventricular ejection fraction (LVEF) between 0.3-0.5 were selected and randomly assigned to MI group and MI+NRG-1 group. Rats in MI+NRG-1 group were treated with recombinant human NRG-1β (100 μg/kg) via tail vein at 2 weeks after operation (twice per week for 6 weeks); while rats in sham-operated group and MI group received equal volume of physiological saline. By the end of administration, echocardiography and small animal positron emission tomography (PET) were performed to detect cardiac function and myocardial glucose uptake. Myocardial morphology and collagen volume fraction, cardiomyocyte apoptosis and reactive oxygen species (ROS) production were evaluated by histopathologic analysis. Myocardial pyruvate dehydrogenase (PDH) and citrate synthase (CS) activity, as well as ATP production were detected by commercial kits. The mRNA and protein expression levels of NRG-1, p-ErbB4, and key factors involved in glucose metabolism (including Glut-4, HK2, PDK4, PDH, CS) were detected by quantitative real-time PCR (qRT-PCR) and Western blot assay, respectively. Results: With the MI model successfully established, the left ventricular ejection fraction(LVEF) and left ventricular shortening fraction(LVFS) were significantly lower in MI group and MI+NRG-1 group than that in sham group (both P<0.01), while there was no significant difference between MI group and MI+NRG-1 group(all P>0.05). After 6 weeks of NRG-1β intervention, the LVEF and LVFS were significantly higher in MI+NRG-1 group than in MI group (both P<0.01). By the end of experiment, PET imaging showed that the mean standardized uptake value (SUVmean) were lower in MI+NRG-1 group than in the sham group (4.06±0.28 vs. 5.18±0.37, P<0.01), while significantly higher than that in MI group (4.06±0.28 vs.2.86±0.49, P<0.01). Histopathological analysis showed that compared with MI group, rats in MI+NRG-1 group exhibited significantly decreased left ventricle collagen volume fraction ((7.83±1.24) % vs. (18.31±3.58) %, P<0.01), cardiomyocyte apoptosis((37.98±4.26)% vs. (67.04±5.38)%, P<0.01), and DHE fluorescence intensity(0.057 28±0.007 06 vs. 0.076 94±0.008 46, P<0.01), indicating that NRG-1β could reduce ROS production. PDH activity, CS activity, and ATP production were significantly higher in MI+NRG-1 group than in MI group (all P<0.05). qRT-PCR demonstrated an upregulated Glut-4, HK2 and CS, but downregulated PDK4 mRNA expression in MI+NRG-1 group compared with MI group (all P<0.01). Western blot assay showed significantly higher protein expression of NRG-1, p-ErbB4, Glut-4, HK2, PDH, CS in MI+NRG-1 group than in MI group (all P<0.01). Conclusion: NRG-1 could improve glucose uptake and utilization in myocardium by activating phosphorylation of myocardial ErbB4 receptor in MI rats, thus providing a therapeutic option for improving energy metabolism after MI.

Observation of D^{0}→K_{1}(1270)^{-}e^{+}ν_{e}. PHYSICAL REVIEW LETTERS 2021; 127:131801. [PMID: 34623854 DOI: 10.1103/physrevlett.127.131801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 07/28/2021] [Accepted: 08/18/2021] [Indexed: 06/13/2023]
Abstract
Using 2.93 fb^{-1} of e^{+}e^{-} collision data taken with the BESIII detector at a center-of-mass energy of 3.773 GeV, the observation of the D^{0}→K_{1}(1270)^{-}e^{+}ν_{e} semileptonic decay is presented. The statistical significance of the decay D^{0}→K_{1}(1270)^{-}e^{+}ν_{e} is greater than 10σ. The branching fraction of D^{0}→K_{1}(1270)^{-}e^{+}ν_{e} is measured to be (1.09±0.13_{-0.16}^{+0.09}±0.12)×10^{-3}. Here, the first uncertainty is statistical, the second is systematic, and the third originates from the assumed branching fraction of K_{1}(1270)^{-}→K^{-}π^{+}π^{-}. The fraction of longitudinal polarization in D^{0}→K_{1}(1270)^{-}e^{+}ν_{e} is determined for the first time to be 0.50±0.19_{stat}±0.08_{syst}.

Abstract
The absolute branching fraction of Λ→pμ^{-}ν[over ¯]_{μ} is reported for the first time based on an e^{+}e^{-} annihilation sample of 10×10^{9} J/ψ events collected with the BESIII detector at sqrt[s]=3.097 GeV. The branching fraction is determined to be B(Λ→pμ^{-}ν[over ¯]_{μ})=[1.48±0.21(stat)±0.08(syst)]×10^{-4}, which is improved by about 30% in precision over the previous indirect measurements. Combining this result with the world average of B(Λ→pe^{-}ν[over ¯]_{e}), we obtain the ratio {[Γ(Λ→pμ^{-}ν[over ¯]_{μ})]/[Γ(Λ→pe^{-}ν[over ¯]_{e})]} to be 0.178±0.028, which agrees with the standard model prediction assuming lepton flavor universality. The asymmetry of the branching fractions of Λ→pμ^{-}ν[over ¯]_{μ} and Λ[over ¯]→p[over ¯]μ^{+}ν_{μ} is also determined, and no evidence for CP violation is found.

Abstract
Objective: To investigate the clinical effect of the radical resection with a proximal incisal edge length of 20-25 mm and 30-35 mm in Siewert type Ⅱ advanced esophagogastric junction adenocarcinoma, to shorten the minimum safe distance of the proximal incisal edge to 20-25 mm. Methods: A retrospective cohort study method was used. The clinical data of 166 patients with Siewert type Ⅱ advanced esophagogastric junction adenocarcinoma who underwent total gastrectomy from January 2017 to August 2020 in the Department of Gastrointestinal Surgery, Heji Hospital Affiliated to Changzhi Medical College were retrospectively collected. According to the proximal incisal edge length, the patients were divided into two groups: the proximal incisal edge length of 20-25 mm group (69 cases) and 30-35 mm group (97 cases). The perioperative conditions and the 6-month follow-up after the operation were compared between the two groups. Results: There was no statistically significant difference in baseline information between the patients in the two groups (P>0.05). The operations of both groups were completed. The intraoperative operation time of the proximal incisal edge length of 20-25 mm group was shorter than that in the proximal incisal edge length of 30-35 mm group ((172±24)and(206±27)min, P<0.001). There were no significant differences in the amount of intraoperative blood loss, the treatment of the diaphragm during the operation and the positive rate of intraoperative freezing of the upper incisal edge between the patients in the two groups (all P>0.05). And there was no significant differences in the first exhaust time, gastric tube removal time, first feeding time and hospital stay after the operation of the two groups (all P>0.05). There was no significant differences in the incidence of anastomotic leakage, anastomotic stenosis, reflux esophagitis and intestinal obstruction after the operation between the patients in the two groups (all P>0.05). And there was no anastomotic leakage case among the 69 cases in the proximal incisal edge length of 20-25 mm group. Postoperative pathological treatment showed no significant differences in the vascular tumor thrombus and nerve infiltration between the two groups (both P>0.05). During the 6-month follow-up, there was no death or tumor recurrence in the two groups, and there was no significant difference in body weight loss at 6 months after the operation between the two groups (P=0.178). Conclusion: When radical resection of Siewert type Ⅱ advanced esophagogastric junction adenocarcinoma is performed, it is feasible to shorten the minimum safe distance of the proximal incisal edge to 20-25 mm under the premise of ensuring R0 resection. The operation time is shortened. Due to the shortening the incisal edge distance, the anastomotic tension is decreased, and the incidence of postoperative anastomotic leakage is also reduced.
