Objective: To investigate the characteristics of mortality of injury among residents in Gusu District, Suzhou City, Jiangsu Province from 2013 to 2023, so as to provide the evidence for developing targeted measures of injury prevention and control. Methods: Gender, age and underlying cause of deaths due to injury in Gusu District were collected through Death Reporting Information System of Chinese Disease Prevention and Control Information System and Jiangsu Death Reporting Information System from January 1, 2013 to December 31, 2023. The crude mortality, Chinese-standardized mortality and world-standardized mortality of injury were analyzed, and the trend in mortality was analyzed using annual percent change (APC). Results: Totally 4 217 deaths due to injury were reported in Gusu District from 2013 to 2023. The crude, Chinese-standardized and world-standardized mortality rates were 51.58/105, 23.24/105 and 21.98/105, respectively, all showing a tendency towards a rise (APC=6.802%, 2.688% and 2.823%, all P<0.05). The crude mortality rate of injury was higher in women than in men (54.61/105 vs. 48.41/105, P<0.05). The five most common causes of injury included fall (32.99/105), traffic accidents (6.03/105), suicide (4.23/105), drowning (3.00/105) and asphyxia (2.16/105), accounting for 93.86% of the total number of deaths. The crude mortality rates of fall, suicide and asphyxia appeared a tendency towards a rise (APC=9.724%, 6.333% and 5.638%, all P<0.05). The crude mortality rates of injury among men, women and overall residents appeared a tendency towards a rise with age (all P<0.05). Fall was the primary cause of injury death among residents aged 65 years and above, and suicide was the primary cause of injury death among residents aged 15 to 44 years. Conclusions The crude mortality of injury appeared a tendency towards a rise in Gusu District from 2013 to 2023. The main causes of death were fall, traffic accidents, suicide, drowning and asphyxia, with the crude mortality of fall, suicide and asphyxia showing an upward trend.

Objective:To supply a reference measure,CD8+CD38+ expressin,AST,TBIL,PT were examined in patients with chronic hepatitis B.Methods:CD8+CD38+ expression of peripheral blood lymphocyte in 38 patients with chromic hepatitis B and 14 patients with liver cirrhosis were detected with flow cytometry. AST,TBIL,PT were also measured at the same time with instruments.Results:(1)CD8+CD38+ expression in patients with choronic hepatitis B and liver cirrcosis elevated significantly compared with those in normal controls. But CD8+CD38+ expression in patients with liver cirrhosis was lower significantly than those with chronic hepatitis B.(2)CD8+CD38+ expression in moderate chronic hepatitis B were higher than those in mild chronic hepatitis B. CD8+CD38+,CD8+,CD38+ expression in severe chronic hepatitis B were higher than those in mild chronic hepatitis B. CD38+ expression in severe chronic hepatitis B was higher than those in moderate chronic hepatitis B. CD8+CD38+,CD8+,CD38+ expression in liver cirrhosis was lower than those in mild,moderate,severe chronic hepatitis B. CD8+ expression in liver cirrhosis was lower than those in severe chronic hepatitis B.(3)CD8+CD38+ expression in patients under AST,TBIL,PT abnormal condition were higher than those in patients under AST,TBIL PT,normal condition.Conclusion:The increasing of CD8+CD38+ expression of peripheral blood lymphocyte in patients with chronic hepstitis B,reflect the fact that cell immunolgy was abnormally activated.There was a remarkable correlation on CD8+CD38+ and AST,TBIL,PT. To test expression of CD8+CD38+ of peripheral blood lymphocyte in chronic hepatitis B has very important clinical reference value on patient′s condition development and diagnosis.

Objective:To study the effiacious based on our experience of precise anatomical hemi-hepatectomy strictly guided by the middle hepatic vein (MHV) for regional to treat intrahepatic hepatolithiasis.Methods:A retrospective analysis was conducted on the data of 47 patients with regional hepatolithiasis treated with hemihepatectomy from July 2015 to July 2019 at the Department of Hepatobiliary and Pancreatic Surgery, The University of Hong Kong-Shenzhen Hospital. The study included 15 males and 32 females, aged (42±15) years. The exposure and preservation of the MHV was included in the precision surgery group ( n=26), and failure to fully expose the MHV or damage to the MHV was included in the control group ( n=21). The operation time, intraoperative blood loss and other surgical data and postoperative complications of the two groups were compared. Results:All patients successfully completed the operation. There was no patient who developed liver failure, and no patient died 90 days after the operations. The operation time (5.2±1.8) h and intraoperative blood loss (620.5±450.8) ml of the precision surgery group were not significantly different from those of the control group (4.9±2.3) h and intraoperative blood loss (760.5±540.2) ml ( P>0.05). A total of 19 patients (40.4%) (7 in the precision surgery group and 12 in the control group) developed 36 post operative complications of various types. The postoperative complication rate in the control group was higher than that in the precision surgery group [47.6%(10/21) vs 19.2% (5/26)], the difference was significant ( P<0.05). All 47 patients were followed-up for 6 to 30 months. For postoperative long-term complications: 5 patients in the control group had residual stones, biliary tract infection, liver abscess, and biliary-enteric anastomosis stenosis with recurrence of stones, and only 2 patients in the precision surgery group were found to have residual stones and biliary-enteric anastomotic stenosis. Stone recurrence, (the incidence of long-term complication) in the control group was significantly higher than that in the precision surgery group [23.8% (5/21) vs 7.7% (2/26)], ( P<0.05). Conclusions:Precise anatomical hemi-hepatectomy strictly guided by MHV for regional hepatolithiasis could more fully remove stones and lesions, and reduced the rate of stone recurrence. It was safe and feasible with favorable efficacy.

Objective:To investigate differentially expressed long noncoding RNAs (lncRNAs) and mRNAs between proliferating and involuting infantile hemangioma (IH) .Methods:Eight IH specimens were surgically resected from 4 children with proliferating IH and 4 with involuting IH in Department of Pediatric Surgery, West China Hospital, Sichuan University from January to March in 2019. Differentially expressed lncRNAs and mRNAs between proliferating and involuting IH (a P value < 0.05 and a fold change ≥ 2.0) were screened by microarray analysis, and verified by real-time fluorescence-based quantitative PCR (qRT-PCR) . Bioinformatics analysis was further performed, including GO and KEGG pathway analyses of differentially expressed mRNAs, construction of a lncRNA-mRNA co-expression network, and prediction of cis-acting target genes of differentially expressed lncRNAs. Results:A total of 405 differentially expressed lncRNAs and 772 differentially expressed mRNAs were identified between the proliferating and involuting IH specimens by using microarray technology. Of them, 108 lncRNAs and 107 mRNAs were downregulated, 297 lncRNAs and 665 mRNAs were upregulated in the proliferating IH specimens. Four lncRNAs (n335248, ENST00000450864, n333319, and n335185) and 4 mRNAs (EDNRA, IFI6, HK2, and ITGA1) were verified by qRT-PCR, and the results were consistent with those of microarray analysis. GO and KEGG enrichment analyses showed that differentially expressed mRNAs were mainly involved in the biological processes blood coagulation, axon guidance, angiogenesis and cell adhesion. Besides, differentially expressed mRNAs were mostly enriched in the metabolic pathways focal cell adhesion, regulation of actin cytoskeleton, leukocyte transendothelial migration and phosphatidylinositol 3-kinase/serine-threonine protein kinase and other signaling pathways. In addition, a lncRNA-mRNA co-expression network was constructed with 23 mRNAs and 58 lncRNAs with the degree ≥ 15.Conclusion:Lots of differentially expressed lncRNAs and mRNAs were identified between proliferating and involuting IH tissues, and these lncRNAs may play important roles in the development of IH by regulating corresponding target mRNAs.

Infantile hemangioma (IH) is the most common benign tumor in infants and young children, with a typical period of proliferation and regression. However, some infantile hemangioma grows rapidly, affects function and even endangers life, and requires active treatment. In recent years, the risk factors for infantile hemangioma have become a hot topic of research. This paper reviews the research status of the risk factors for infantile hemangioma from the aspects of genetic factors and maternal factors, so as to provide help for early clinical diagnosis and treatment.

Objective:To construct a model of nursing teaching rounds in dental clinics, and to provide a reference for the implementation of nursing teaching activities in dental clinics.Methods:Using the constructivism learning theory framework, we developed a preliminary draft of a teaching rounds model for dental outpatient nursing according to literature review, cross-sectional survey, and brainstorming results. Two rounds of Delphi consultation with 21 experts from across China were conducted to determine the teaching rounds model for dental outpatient nursing. Data entry and statistical analysis were performed with Excel 2016 and SPSS 26.0 software.Results:In the two rounds of expert consultation, the questionnaire response rates were both 100%; the expert authority coefficients were 0.865 and 0.873, respectively; and the Kendall's coefficients of concordance were 0.116 and 0.164, respectively. The established dental outpatient nursing teaching rounds model included 7 first-level items and 22 second-level items.Conclusions:The dental outpatient nursing teaching rounds model constructed in this study is scientific, reliable, and practical, which can provide guidance for conducting nursing teaching rounds in dental clinics.

Objective: To study the application of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in hepatocellular carcinoma with mild-to-moderate liver cirrhosis. Methods: There are 14 patients with hepatocellular carcinoma underwent ALPPS at the Department of Hepatobiliary and Pancreatic Surgery, Hong Kong University-Shenzhen Hospital from April 2014 to December 2017. The clinical data was retrospectively studied. The studying objects consisted of 9 males and 5 females, aged from 26 to 71 years old with the average age of 51, all cases were of Child-Pugh grade A. The degree of liver cirrhosis, operation and postoperative complications were analyzed. Results: All 14 patients completed the ALPPS, 1 patient died post stage 2 operation with liver failure. Comparing the groups with no liver cirrhosis (n=4) with the groups of mild liver cirrhosis (n=5) and moderate liver cirrhosis (n=5), the future liver remnant liver volume growth rates were 58%, 46% and 45.6%, respectively. The average operation intervals were 9.0, 11.2 and 12.8 days, respectively. Postoperative complications occurred in 4 patients: 2 patients with liver failure, 1 patient with intestinal obstruction, and 1 patient with hepatic ascites. Conclusion ALPPS for Child-Pugh grade A, hepatocellular carcinoma with mild-to-moderate liver cirrhosis treatment is safe and feasible.

Objective:To preliminarily assess the clinical value of sirolimus combined with prednisone in the treatment of Kaposiform hemangioendothelioma (KHE) complicated by Kasabach-Merritt phenomenon (KMP) .Methods:A retrospective study was conducted. General clinical data and relevant data on efficacy and adverse reactions were collected from 36 patients with KHE complicated by KMP, who received oral sirolimus combined with prednisone in Department of Pediatric Surgery, West China Hospital, Sichuan University from January 2011 to January 2018.Results:Among the 36 patients with KHE complicated by KMP, the male-to-female ratio was 1∶0.8; their average age was 15.0 months (range, 4.0 - 60.0 months) , and the average age of onset was 6.3 months (range, 0.8 - 48.0 months) ; 32 (88.9%) patients were diagnosed with mixed KHE, and 4 (11.1%) with deep KHE; the tumor size ranged from 2.5 cm × 4.0 cm to 20.0 cm × 24.0 cm. During the combined treatment, the average duration of prednisone administration was 6.4 weeks (range, 5.0 - 9.0 weeks) , and that of sirolimus administration was 19.3 months (range, 13.0 - 27.0 months) . After 1-5 weeks of combined treatment, platelet counts and fibrinogen levels of the 36 patients gradually returned to normal. After short-term prednisone combined with long-term sirolimus treatment, the average disease severity score decreased from 4.0 before treatment to 2.4 at 6 months and 1.6 at 12 months. After 12 months of the combined treatment, tumors mostly regressed in 32 (88.9%) patients, partially regressed in 3 (8.3%) , showed no obvious change in 1 (2.8%) . During the treatment, common adverse reactions included gastrointestinal discomfort and oral ulcers, no patient discontinued the treatment due to severe adverse reactions, and no drug toxicity-related death occurred.Conclusion:Sirolimus combined with prednisone is effective and safe for the treatment of KHE complicated by KMP.

Objective:To investigate the similarities and differences in clinical manifestations, lesion features, treatment options and prognosis in patients with kaposiform hemangioendothelioma (KHE) and tufted angioma (TA).Methods:The clinical data of KHE patients and TA patients diagnosed and treated in West China Hospital of Sichuan University from August 2016 to June 2020 were retrospectively analyzed. The similarities and differences in gender, the age of onset, clinical features, complications, histopathology, imaging manifestations, treatment and prognosis of the two diseases were compared. The χ2 test or Fisher’s exact test were used to analyze the qualitative data. The Mann-Whitney U test was used to analyze the quantitative data of the two groups that did not conform to the normal distribution. P<0.05 was considered to be statistically significant. Results:A total of 217 patients were included, including 183 patients with KHE and 34 patients with TA. There was no significant difference between KHE and TA in male to female ratio ( χ2=0.44, P=0.510), the age of onset ( U=2 757.00, Z=-1.09, P=0.278) and the sites of lesion ( χ2=3.64, P=0.162). The mixed type of KHE was the most common, reaching 63.39% (116/183), while the superficial type of TA was the most common, reaching 88.24% (30/34). The lesion diameter of KHE patients was 6.30(4.40, 9.70) cm, which was larger than that of TA patients 2.95(2.05, 4.03) cm, and the difference was statistically significant ( U=967.50, Z=-6.38, P<0.001). KHE is more likely to involve skeletal muscle, and cause thrombocytopenia and severe fibrinogenopenia. KHE mainly involved the dermis, subcutaneous tissue and even deep muscles, and manifested as an infiltrative mass. Magnetic resonance imaging (MRI) showed mass diffuse with high signal on T 2 phase. TA was often a superficial lesion that only involved the subcutaneous fat layer and was lumpy. MRI showed that the high signal was confined to the subcutaneous fat layer. The total effective rate of KHE [KHE(85.79%) vs. TA(91.18%)] and the total effective rate of drug therapy [KHE(85.32%) vs. TA(95.65%)] were lower than those of TA. Conclusions:Compared with TA, KHE has a larger tumor diameter, higher invasiveness, higher risk of complications. In addition, treatment plan was more complicated and treatment response rate was lower in patients with KHE compared with those in patients with TA.
