RESUMO
BACKGROUND@#Hypertensive heart disease (HHD) poses a public health challenge, but data on its burden and trends among older adults are scarce. This study aimed to identify trends in the burden of HHD among older adults between 1990 and 2019 at the global, regional, and national levels.@*METHODS@#Using the Global Burden of Diseases study 2019 data, we assessed HHD prevalence, death, and disability-adjusted life-year (DALY) rates for individuals aged 60-89 years at the global, regional, and national levels and estimated their average annual percentage changes (AAPCs) between 1990 and 2019 using joinpoint regression analysis.@*RESULTS@#In 2019, there were 14.35 million HHD prevalent cases, 0.85 million deaths, and 14.56 million DALYs in older adults. Between 1990 and 2019, the prevalence of HHD increased globally {AAPC, 0.38 (95% confidence interval [CI], 0.36, 0.41)} with decreases observed in mortality (AAPC, -0.83 [95% CI, -0.99, -0.66]) and the DALY rate (AAPC, -1.03 [95% CI, -1.19, -0.87]). This overall global trend pattern was essentially maintained for sex, age group, and sociodemographic index (SDI) quintile except for non-significant changes in the prevalence of HHD in those aged 70-74 years and in the middle SDI quintile. Notably, males had a higher HHD prevalence rate. However, HHD-related mortality and the DALY rate were higher in females. The middle SDI quintile experienced the largest decreases in mortality and the DALY rate, with a non-significant decline in prevalence between 1990 and 2019. There were significant discrepancies in the HHD burden and its trends across regions and countries.@*CONCLUSIONS@#In the past three decades, there has been an overall increasing trend in the prevalence of HHD among older adults worldwide despite decreasing trends in mortality and the DALY rate. Better management of hypertension, and prevention and control of HHD are needed in older adults.

Objective:To explore the mechanism of gypenoside ⅩⅦ against cerebral ischemia/reperfusion (I/R) through nuclear factor erythroid 2-related factor 2/antioxidant responsive element (Nrf2/ARE) signaling pathway.Methods:Forty SPF Sprague Dawley (SD) rats were randomly divided into sham operated group, I/R model group, 25, 50 and 100 mg/kg gypenoside ⅩⅦ groups ( n = 8). Gypenoside ⅩⅦ groups were administered 25, 50 or 100 mg/kg (0.01 mL/g) gypenoside ⅩⅦ by intragastric administration for 14 days; the other two groups received the same dose of saline. Rat cerebral I/R model was established by modified line bolt method; rats in the sham operated group underwent the same procedure without producing substantial embolization. After 24 hours of reperfusion, the neurological deficit scores of the rats in each group were assessed. Rat abdominal aortic whole blood was collected and the serum reactive oxygen species (ROS), heme oxygenase-1 (HO-1), γ-glutamylcysteine synthase (γ-GCS), superoxide dismutase (SOD), quinone NADH oxidoreductase 1 (NQO1), and malondialdehyde (MDA) were detected. Then whole brain tissue was harvested and penumbra tissue was isolated from cerebral cortex, the general condition of rat brain tissue and the volume of cerebral infarction were evaluated, the histopathological changes in the brain were observed under light microscopy, the mRNA expressions of Nrf2 and Keap1 were measured by real-time fluorescent quantitative polymerase chain reaction (RT-qPCR), the protein expressions of Nrf2 and Keap1 were determined by Western blotting. Results:After 24 hours of reperfusion, compared with the sham operated group, the score of neurological deficit and infarct volume were significantly increased, the NQO1, SOD and γ-GCS levels in serum were significantly decreased, MDA, HO-1 and ROS levels in serum were significantly increased, the Nrf2 and Keap1 mRNA and protein expressions in the ischemic penumbra were significantly increased in rats from I/R model group. Compared with the I/R model group, the neurological deficit scores (1.50±0.53, 1.37±0.52 vs. 2.75±0.46) and brain infarct volume [(19.8±5.1)%, (21.4±6.4)% vs. (42.3±5.8)%] were significantly reduced, serum NQO1, SOD, HO-1 and γ-GCS were significantly increased [NQO1 (ng/L): 186.05±10.38, 220.75±16.22 vs. 131.36±5.95, SOD (kU/L): 63.23±5.30, 72.70±8.62 vs. 36.75±6.55, HO-1 (ng/L): 60.57±7.93, 60.35±4.72 vs. 42.72±4.95, γ-GCS (kU/L): 8.81±0.53, 8.72±0.69 vs. 6.80±0.56], serum MDA and ROS levels were significantly reduced [MDA (μmol/L): 5.94±0.66, 5.61±0.53 vs. 10.88±1.34, ROS (kU/L): 69.11±4.23, 67.12±4.52 vs. 104.43±7.54], the mRNA and protein expressions of Nrf2 and Keap1 in the ischemic penumbra were significantly increased in rats from 50 mg/kg and 100 mg/kg gypenoside ⅩⅦ groups [Nrf2 mRNA (2 -△△Ct): 1.90±0.13, 2.13±0.18 vs. 1.48±0.11, Keap1 mRNA (2 -△△Ct): 1.78±0.11, 1.85±0.10 vs. 1.43±0.10, Nrf2/β-actin: 0.73±0.04, 0.79±0.03 vs. 0.60±0.03, Keap1/β-actin: 0.71±0.01, 0.76±0.03 vs. 0.61±0.01], all the comparative differences were statistically significant (all P < 0.01); 25 mg/kg gypenoside ⅩⅦ had no significant effect. Conclusion:Gypenoside ⅩⅦ (50 mg/kg and 100 mg/kg) may play a role in anti-cerebral I/R injury by regulating NQO1, SOD, HO-1, γ-GCS, ROS and MDA through Nrf2/ARE signaling pathway.
RESUMO
Objective:To provide reference for clinical diagnosis and treatment of hepatic cystic echinococcosis by analyzing the clinical characteristics of these patients.Methods:Clinical data of 15 patients with hepatic cystic echinococcosis hospitalized in the Second Hospital of Lanzhou University from April 22, 2019 to March 5, 2022 were collected. The general data, clinical manifestations, abdominal imaging results, treatment and outcome of the included patients were retrospectively analyzed.Results:The age of 15 patients with hepatic cystic echinococcosis ranged from 39 to 78 years, with a median age of 51 years. Among the 15 patients, 12 were farmers, two were freelance workers, and one was unknown. Eleven patients presented with abdominal pain and fatigue, one patient presented with obstructive jaundice, and three patients whom were found by physical examination did not complain of obvious discomfort. Echinococcoid cysts were located at the right lobe of the liver in eight patients, at the left lobe of the liver in five patients, and with multiple lesions in the left and right lobes of the liver in two patients. Two patients received conservative therapy. All the 13 patients who received surgical treatment recovered without complications, such as biliary fistula and subphrenic infection. The clinical symptoms including abdominal pain and fatigue were relieved significantly after surgery. The hospital stay were four to 23 days. All patients were administrated with albendazole (400 mg once daily).Conclusions:Hepatic cystic echinococcosis is more common in the right lobe of the liver, with atypical clinical symptoms. Preoperative imaging diagnosis and postoperative pathological examination are necessary for diagnosis. Surgery is the most effective treatment at present, and albendazole should be taken regularly in all patients.
RESUMO
Objective:To explore the influence on the willingness to seek medical treatment by revising the recommendations for prevention and treatment in the medical examination report.Methods:Revising the prevention and treatment recommendations for four diseases, including proteinuria, hyperuricemia, hydronephrosis and renal insufficiency to clearly inform the etiology and prognosis of them. Using a cross-sectional study method, pre-revision prevention and treatment recommendations (version A) and post-revision prevention and treatment recommendations (version B) questionnaires were randomly distributed to medical examiners and at the health management center of our hospital in Wuhan. An ordinal logistic regression model and a binary logistic regression model were used to analyze the correlation of the understanding of diseases and the willingness to seek medical treatment with different connotation of the prevention and treatment recommendations, respectively.Results:A total of 530 valid questionnaires were collected, of which 267 were from version A and 263 from version B. There was no significant difference in the socio-demographic profile of respondents between version A and version B. For the four high risk factors of kidney diseases mentioned above, version B was better than version A in terms of understanding and willingness to seek medical treatment ( P<0.001). The level of understanding OR(95% CI) were 3.691(2.570, 5.301), 2.238(1.511, 3.320), 4.293(6.353, 2.903) and 5.275(7.877, 3.529) respectively. The willingness to seek medical treatment OR(95% CI) were 3.554(2.441, 5.175), 2.850(1.975, 4.114), 5.144(3.457, 7.654) and 4.225(2.868, 6.224) respectively. All the P values were lower than 0.001. Conclusions:Improving the connotation of prevention and treatment recommendations in the medical examination report can help increase the willingness for early medical consultation.
RESUMO
Objective:By analyzing the clinical data of patients with primary duodenal adenocarcinoma (PDA), the risk factors affecting the postoperative prognosis of PDA patients were discussed.Methods:The clinical data of 191 patients diagnosed with PDA in Peking University First Hospital from Jan 2009 to Dec 2022 were collected. The survival rate was calculated and the survival curve was plotted by Kaplan-Meier method. Univariate analysis was performed by Log-Rank test, and multivariate analysis was performed by COX proportional hazards regression model to obtain independent risk factors.Results:The median age of onset in patients with PDA is 65 years old, and the most common symptoms are abdominal pain and abdominal distension. Prognostic analysis showed that the survival rates at 1, 3 and 5 years were 73.8%, 44.6%, and 23.0%. The analysis of Cox risk proportional regression model showed that preoperative CA19-9 level, depth of tumor invasion, degree of differentiation, TNM stage, and surgical mode were independent risk factors for the prognosis of PDA (all P<0.01). Conclusion:The overall incidence of PDA is low, but the prognosis is rather poor. Multvariable factors are associated with its prognosis and surgery is still the mainstay for hope of cure.
RESUMO
@#Lung cancer is the malignancy with the highest incidence and mortality rate in China. In recent years, the popular use of low-dose computed tomography in the population has led to an increase in the detection rate of pulmonary nodules. The National Comprehensive Cancer Network (NCCN) updated and released the NCCN clinical practice guidelines in oncology for non-small cell lung cancer (version 2.2023) on February 17, 2023. This article will interpret the main updates of the new guideline and compare it with the domestic lung cancer treatment guidelines, providing new ideas for the diagnosis and treatment of lung cancer for Chinese clinicians.
RESUMO
@#Objective To investigate the clinical characteristics and risk factors for perioperative lung surgery patients with SARS‐CoV‐2 Omicron variant infection. Methods The clinical data of patients who underwent lung surgery at the Department of Thoracic Surgery, Renmin Hospital of Wuhan University from December 1, 2022 to January 9, 2023 were retrospectively analyzed. The patients were divided into an infection group and a non-infection group according to whether they were infected with SARS-CoV-2. And the clinical data of two groups were collected and compared. Multiple linear regression analysis was used to explore the risk factors affecting the time of hospitalization. Results A total of 70 patients were enrolled in this study, including 36 (51.4%) males and 34 (48.6%) females at a median age of 61.0 (49.0, 66.8) years. There were 28 patients in the infection group and 42 patients in the non-infection group. The proportion of preoperative abnormal coagulation function and the risk of postoperative pulmonary infection in perioperative patients infected with SARS-CoV-2 were higher than those in the non-infection group (P<0.05). Subgroup analysis found that patients with preoperative SARS-CoV-2 infection were more likely to have pulmonary infection after surgery, but did not prolong the time of hospitalization or increase the risk of severe disease rate. The patients with postoperative SARS-CoV-2 infection had worse clinical prognosis, including longer time of hospitalization (P=0.004), higher ICU admission rate (P=0.000), higher lung infection rate (P=0.003) and respiratory failure rate (P=0.000). Multiple linear regression analysis showed that gender and extent of surgery were independent risk factors for prolonged hospitalization time. Conclusion Preoperative infection with SARS-CoV-2 Omicron variant will increase the risk of pulmonary infection, but it will not affect the clinical prognosis. However, postoperative infection with SARS-CoV-2 Omicron variant will still prolong the time of hospitalization, increase the ICU rate, and the risk of pulmonary complications.
RESUMO
@#Lung cancer is the malignant tumor with the highest incidence rate in men and the highest mortality rate in men and women in China, and the incidence and mortality rates are still increasing. Lung cancer screening is an important initiative for early detection of lung cancer and improvement of prognosis.

The guidelines are based on the latest research advances and high-level evidence-based medical evidence to establish screening criteria for lung cancer, especially for non-small cell lung cancer, which is the most common and highly regarded type of lung cancer, and has received widespread attention from physicians worldwide. In this article, the latest version of the guideline will be interpreted based on China's national situation and Chinese lung cancer screening guidelines, with the aim of providing an updated reference for lung cancer screening in China.
RESUMO
Children with certain comorbidities and immunocompromising conditions are highly vulnerable to SARS-CoV-2 infection. Vaccination against SARS-CoV-2 is an important strategy to reduce death， critical illness and overall disease burden. With the evolving and increasing transmission of SARS-CoV-2， universal vaccination is essential to achieve this goal. Children with special medical conditions are considered as the priorities for SARS-CoV-2 vaccination. However， vaccine hesitancy towards the implementation of SARS-CoV-2 vaccination currently remains an urgent challenge. In order to promote the sustainable vaccination for those children in Shanghai as well as China， Shanghai municipal center for disease control and prevention， together with the national children’s medical center， children’s hospital of Fudan university and the expert group on immunization planning of the Shanghai preventive medicine association， organized a consensus expert working group to formulate the evidence-based recommendations and implementation suggestions for children with common chronic diseases， allergy history， diseases involving adverse events related to vaccination， and immunocompromising conditions， based on the published evidence of SARS-CoV-2 vaccination for populations and children with special medical conditions.
RESUMO
Objective:To determine the predictive value of serum neurofilament light chain (NfL) on neurologic function in out-of-hospital cardiac arrest (OHCA) patients.Methods:The clinical data of 96 OHCA patients admitted to Cangzhou Central Hospital from January 2018 to March 2022 were retrospectively analyzed. According to the Glasgow-Pittsburgh cerebral performance category (CPC) upon hospital discharge, the patients were divided into the favorable neurologic function (grade 1-2) and poor neurologic function (grade 3-5) groups. The difference of serum NfL was compared between the two groups, and the relationship between serum NfL and neurologic function was assessed using correlation analysis and logistic regression analysis. The area under the curve (AUC), sensitivity, and specificity of serum Nfl were calculated by receiver operating characteristic (ROC) curve. Hanley & McNeil method test was used to compare the difference of AUCs between serum NfL and neuron specific enolase (NSE).Results:Twenty-six percent (25/96) patients were discharged with favorable neurologic function. Serum NfL in the favorable neurological function group was significantly lower than that in the poor neurologic function group (47.6 pg/mL vs. 261.4 pg/mL, P<0.001). Correlation analysis showed that serum NfL was positively correlated with neurologic function ( r=0.69, P<0.001). Logistic regression analysis showed that serum NfL was independently associated with neurological function ( OR=0.92, 95% CI: 0.86-0.98; P=0.010). ROC curve indicated that the AUC of serum NfL in predicting poor neurologic function was 0.95 (95% CI: 0.92-0.99), with a sensitivity of 84.5% and a specificity of 100% at the cutoff value of 80.0 pg/mL. The AUC of serum NSE in predicting poor neurologic function was 0.79 (95% CI: 0.69-0.89), with a sensitivity of 67.6% and a specificity of 80.0% at the cutoff value of 45.1 ng/mL. A pairwise comparison using Hanley & McNeil method showed that the AUC of serum NfL in predicting poor neurologic function was higher than that of NSE ( Z=3.22, P=0.001). Conclusions:Serum NfL is helpful for clinician to predict neurologic function in OHCA patients.
RESUMO
Objective:To observe the variation rend of serum creatinine(SCr)and estimated glomerular filtration rate(eGFR)with aging, and to explore the warning range of SCr for screening low eGFR of the elderly.Methods:A retrospective cross-sectional study was performed in 10 3513 participants, including 14 221 in 18-29 years old, 29 763 in 30-39 years old, 23 151 in 40-49 years old, 18 838 in 50-59 years old, 10 019 in 60-69 years old, 5 009 in 70-79 years old, 2 512 aged ≥80 years old.We adopted CKD-EPI formula based on Chronic Kidney Disease Epidemiology Collaboration(CKD-EPISCR)formula recommended by the Global Organization for Improving Outcomes in Kidney Disease 2012 to calculate eGFR.The SCr and eGFR levels were calculated according to age to show the trend of these with aging.Further, we used percentage to investigate the distribution of eGFR in population with normal SCr, and the percentile method to establish the warning range of SCr in the older adults.Results:With aging, SCr level showed an elevating trend in women( F=340.80, P<0.001), and gradually increased in men older than 50 years( F=111.05, P<0.001)and eGFR declined with increasing age( F=8 301.60, 9 114.53, P<0.001). In population with normal SCr, the proportions of eGFR<60 and 60-75 ml·min -1·1.73m -2 were 3.83%(661/17 280)and 12.50%(2 160/17 280)in older adults aged 60-74 years respectively, but were 10.39%(488/4 699)and 22.75%(1 069/4 699)in old-older adults aged 75 years and over respectively, and were 0.07%(56/84 145)and 0.91%(762/84 145)in younger adults below 60 years old respectively.In the same distribution of eGFR, SCr levels of older adults aged 60-74 years and old-older adults aged 75 years and over were lower than that of younger population( P<0.001). In old-older adults aged 75 years and over, the warning range of SCr was 98.76-126.03 μmol/L for men and 95.12-130.00 μmol/L for women in individuals with 45 ≤ eGFR<60 ml·min -1·1.73m -2. Conclusions:The SCr level of older adults is lower than younger individuals in same distribution of eGFR.SCr level is still in the reference range in some of older individuals with eGFR-confirmed renal function impairment.The warning range of SCr is needed, especially in older adults, so as to provide reference for the rational use of medicine and disease management.
RESUMO
The postoperative pathological staging system (pTNM) has become an important reference for the selection of various tumor treatment strategies and prognosis evaluation at a global scale, and is a powerful predictor of the prognosis of a variety of solid tumors, but the prognosis is still different in patients with the same pTNM staging. In recent years, studies have confirmed that the negative lymph nodes count (NLNC) is related to the prognosis of a variety of solid tumors. Higher NLNC can improve the prognosis of cancer patients, and NLNC can reduce staging migration, which is expected to be a supplement to the pTNM staging system. This article reviews the value of NLNC in the prognosis of solid tumors.
RESUMO
Objective To explore the influence of negative lymph node count (NLNC) on the prognosis of patients with gastric signet ring cell carcinoma (GSRC) and develop a prognostic nomogram based on NLNC. Methods On the basis of the SEER database, 2 101 patients diagnosed with GSRC were collected and randomly divided into the modeling group and validation group to test the relationship between clinicopathological characteristics and the prognosis of GSRC. The multivariate Cox proportional hazard regression model was used to analyze the independent risk factors affecting overall survival and establish a prognostic prediction model. The consistency index (C-index), calibration curve, net reclassification index (NRI), integrated discrimination improvement (IDI), and decision curve analysis (DCA) were used to evaluate the accuracy and clinical applicability of the nomogram. Results All patients were divided according to the ratio of 7:3, with 1 473 in the modeling group and 628 in the validation group. NLNC > 10 (HR=0.578, 95%CI: 0.504-0.662, P < 0.001) was a protective factor for the prognosis of patients with GSRC, and the nomogram model was established based on multivariate Cox proportional hazards model. The C-index values of the nomogram were 0.737 (95%CI: 0.720-0.753) and 0.724 (95%CI: 0.699-0.749) in the modeling and validation groups, respectively, showing good discrimination. The calibration curves showed high consistency of the model. NRI=17.77%, continuous NRI=36.34%, and IDI=4.2% indicated that the model had positive returns compared with the traditional model. The DCA was far from the baseline, indicating that the model had good clinical applicability. Conclusion The increase in NLNC is a favorable factor for the prognosis of patients with GSRC, and a relatively accurate nomogram was established to predict the prognosis of patients with GSRC and help clinicians conduct individualized prognostic evaluations.
RESUMO
Objective:To screen out the potential key genes of sepsis-associated acute kidney injury (AKI), and provide theoretical and experimental evidence for the treatment of sepsis-associated AKI.Methods:① Bioinformatics analysis: two gene expression datasets (GSE30718 and GSE53773) were downloaded for bioinformatics analysis from the Gene Expression Omnibus (GEO). These two datasets recorded mRNA microarray data from kidney biopsies before and after kidney transplantation, and a subset of patients developed AKI after kidney transplantation. Differential analysis was conducted, and the genes with the same differential expression and a higher area under the receiver operator characteristic curve (AUC) in both databases were used as the target gene for subsequent cell experiments. ② Cell validation experiment: human proximal renal tubular cells HK2 were cultured in vitro, and lipopolysaccharide (LPS) was used for establishing LPS-HK2 cell model (LPS 10 mg/L for 6 hours, LPS model group), and the blank control group was set. Then, small interfering RNA (siRNA) technology was used to knock down the target gene obtained by bioinformatics analysis in LPS-HK2 cells (gene knockdown group), and a gene negative control group was set. The real-time fluorescent quantitative reverse transcription-polymerase chain reaction (RT-qPCR) technique was used to detect the expression of the target gene in HK2 cells. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of inflammatory factors in the cell supernatants. Western blotting was used to detect the expressions of key apoptosis proteins. Results:① Results of bioinformatics analysis: 325 genes in the two datasets showed the same expression trend, of which 144 were significantly down-regulated and 181 were significantly up-regulated, while the expression difference of secretory leukocyte protease inhibitor (SLPI) in the two datasets was both statistically significant. Further receiver operator characteristic curve (ROC curve) analysis confirmed that the SLPI expression in GSE30718 and GSE53773 datasets had a high diagnostic efficiency for AKI, with AUC of 0.83 and 0.92, respectively. Therefore, SLPI was selected as the target gene for subsequent cell validation experiment. ② Cell validation experiment: the RT-qPCR analysis showed that the expression of SLPI in LPS-HK2 cells of the LPS model group was significantly higher than that of the blank control group (2 -ΔΔCT: 1.80±0.14 vs. 1.00±0.11, P < 0.01), and the change trend was the same with the results of bioinformatics analysis. Furthermore, knockdown SLPI gene analysis showed that the levels of inflammatory factors in LPS-HK2 cells supernatants in the gene knockdown group were significantly higher than those in the negative control group [Interleukin-6 (IL-6, ng/L): 509.58±27.08 vs. 253.87±75.83, IL-1β (ng/L): 490.99±49.52 vs. 239.67±26.97, tumor necrosis factor-α (TNF-α, ng/L): 755.22±48.66 vs. 502.06±10.92, all P < 0.01]. The above results indicated that SLPI could inhibit the inflammatory response of HK2 cells induced by LPS. The expressions of key apoptosis proteins Bax and caspase-3 in LPS-HK2 cells in the gene knockdown group were significantly higher than those in the negative control group [Bax protein (Bax/GAPDH): 1.38±0.12 vs. 1.00±0.10, caspase-3 protein (caspase-3/GAPDH): 1.44±0.15 vs. 1.00±0.11, both P < 0.05], and Bcl-2 expression was significantly decreased (Bcl-2/GAPDH: 0.83±0.08 vs. 1.00±0.05, P < 0.05), the above results indicated that SLPI could inhibit the apoptosis of cells in the inflammatory response. Conclusion:SLPI can inhibit the inflammatory response and apoptosis of HK2 cells induced by LPS, which may be involved in the protective mechanism of renal tubular cells in the response to sepsis, and is a potential target for the treatment of sepsis-associated AKI.

The clinicopathological data of 298 patients with advanced gastric cancer who underwent Da Vinci robotic surgical system radical gastrectomy in the 940th Hospital of Joint Logistics Support Force of Chinese People's Liberation Army from January 2017 to June 2019 were collected. There were 253 males and 45 females, aged from 24 to 86 years, with a median age of 60 years. Of the 298 patients, 275 cases underwent no serious postoperative complications and 23 cases underwent serious postoperative complications. Observation indicators: (1) serious postoperative complications; (2) analysis of risk factors for serious postoperative complications after Da Vinci robotic surgical system radical gastrectomy of gastric cancer; (3) performance evaluation of the predictive indicators. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the rank sum test. Univariate analysis was conducted using the chi-square test. Multivariate analysis was conducted using Logistic regression model. The receiver operating characteristic curve was drawn and the area under curve (AUC) was used to compare and estimate the efficiency of diagnostic criteria. The value of Youden index was used to determine the optimal cut-off point. Results:(1) Serious postoperative complications: of the 298 patients, 23 cases underwent complications classified ≥grade Ⅲa of Clavien-Dindo classifica-tion, including 10 cases with grade Ⅲa complications, 7 cases with grade Ⅲb complications, 4 cases with grade Ⅳa complications, 1 case with grade Ⅳb complications and 1 case with grade Ⅴ complications. (2) Analysis of risk factors for serious postoperative complications after Da Vinci robotic surgical system radical gastrectomy of gastric cancer. Results of univariate analysis showed that operation time, indicators of C-reactive protein concentration and neutrophil count at post-operative day 1, and indicators of C-reactive protein concentration, white blood cells count, neutrophil count and platelet count at postoperative day 3 and pathological stage were related factors affecting serious complications for advanced gastric cancer after Da Vinci robotic surgical system radical gastrectomy ( χ2=7.671, 4.504, 5.045, 48.293, 9.575, 15.436, 13.731, 9.537, P<0.05). Results of multivariate analysis showed that the operation time ≥250 minutes, the concentration of C-reactive protein at postoperative day 3 ≥16.65 mg/dL, the neutrophil count at postoperative day 3 ≥8.167×10 9/L, the platelet count at postoperative day 3 ≥218×10 9/L and the pathological stage of tumor as stage Ⅱ and stage Ⅲ were independent risk factors affecting serious complications for advanced gastric cancer after Da Vinci robotic surgical system radical gastrectomy ( odds ratio=3.721, 16.084, 6.056, 6.893, 12.455, 95% confidence interval: 1.032-13.421, 4.657-55.547, 1.073-34.163, 1.798-26.423, 1.338-115.930, P<0.05). (3) Performance evaluation of the predictive indicators: the C-reactive protein concentration at postoperative day 3 was a high-performance predictor with the AUC as 0.851 (95% c onfidence interval: 0.780-0.921, P<0.05) and neutrophil count and platelet count at postoperative day 3 were low-performance predictors with the AUC as 0.659 and 0.666 (95% confidence interval: 0.570-0.748 and 0.581-0.750, P<0.05).

Objective:To investigate the effect of timing of surgical treatment on renal function of children with solitary kidney and ureteropelvic junction obstruction (UPJO).Methods:The clinical data of patients with solitary kidney and UPJO admitted to Beijing Children′s Hospital, Capital Medical University and Shunyi Women′s and Children′s Hospital of Beijing Children′s Hospital from January 2006 to January 2018 were retrospectively analyzed.A total of 23 cases were enrolled, including 16 males and 7 females.The age of first visit ranged from 1 day to 15 years and 8 months (average: 2 years and 2 months). All the patients were conservatively treated for an average of 2 years and 9 months.SPSS 20.0 software was used for data analysis.Results:All patients received Anderson-Hynes pyeloplasty(A-H operation), and the age at operation ranged from 10 months to 16 years and 4 months, with an average of 4 years and 11 months.There were only 2 cases under 1 year old (10 months old and 11 months old, respectively). The double J stent was retained for 2 months after operation, and intravenous pyelography(IVP) was reexamined at 3 months after operation.The results showed that hydronephrosis either had no obvious change or was alleviated in different degrees.In 3 cases, IVP remained undetected for 40 minutes before operation.After operation, IVP was detected at 10-20 minutes.The follow-up period ranged from 1 year and 1 month to 10 years, with an average of 3 years and 9 months.Urinary ultrasound showed that the degree of pyeloplasty was less severe than that before operation.Conclusions:Close follow-up visits and conservative treatment of solitary kidney with UPJO are safe after 6 months.The first choice of operation is pyeloplasty.
RESUMO
@#Objective To summarize the experience of surgical treatment of asphyxiating thoracic dysplasia (Jeune syndrome). Methods A total of 15 patients with asphyxiating thoracic dysplasia from August 2018 to April 2020 in our hospital were retrospectively included. There were 7 males and 8 females, aged 1-25 (8.87±6.71) years. Special steel bars were used to correct the growth direction of the rib and costal cartilage. Meanwhile, the concave and convex deformities of the chest wall on both sides were corrected to increase the chest volume and correct the thoracic deformity. Results The contour appearance of the chest wall of all patients changed after the operation. The shape was close to normal, and the symptoms of hypoxia were improved. The operation time was 147.73±59.78 min, intraoperative bleeding volume was 105.67±91.90 mL, ICU stay time was 14.20±13.54 d and hospital stay time was 26.00±17.87 d. Eleven patients were directly extubated after the operation, 4 patients underwent tracheotomy and received assisted respiration, and the assisted respiration time was 19, 13, 22 and 12 days, respectively. The postoperative chest circumference was significantly increased, and the blood oxygen saturation was significantly improved. There were 5 patients with cardiac insufficiency, and 3 of them were improved by cardiotonic therapy, 2 of them died of heart failure on the 2nd and 31st day after the operation, respectively. Abdominal distention occurred in 10 patients after operation, and 5 of them were obstinate and eliminated by comprehensive treatment. All patients were followed up. The appearance of thorax was improved obviously and there was no sign of compression in lungs. One 13-year-old patient developed respiratory discomfort 3 months after the operation, and the symptoms were relieved after self-administration of oxygen. A 25-year-old patient developed cardiac insufficiency half a month after the discharge, and the symptoms disappeared after cardiotonic treatment. Four patients took out the steel bars in 13, 13, 15 and 17 months after the operation, respectively. The appearance of thorax remained well after the operation. The imaging examination showed that the position of bone structure was normal, the lung field was clear, and there was no sign of chronic inflammation. Conclusion This technique is a safe and simple operation method. It can not only eliminate the deformity of chest wall, but also increase the volume of chest obviously. However, the long-term effect needs to be further evaluated.

OBJECTIVE@#To investigate the association between single nucleotide polymorphism of NUDT15 gene (SNP rs116855232) and hepatotoxicity in children with acute lymphocytic leukemia (ALL).@*METHODS@#A total of 135 children with ALL in Shandong Province were recruited in this study, and patients were divided into two groups based on the presence of liver injury. Genotypes of each patient were detected using PCR and Sanger sequencing. Clinical data and the average dose of 6-mercaptopurine (6-MP) were collected and analyzed by SPSS 19.0 software.@*RESULTS@#Respectively, 99 patients were found with CC genotype, 32 patients with CT genotype and 4 patients with TT genotype. Compared with ALL patients without hepatotoxicity, there was a difference in genotypes between the two groups in the initial stage of chemotherapy for leukemia (Chi@*CONCLUSION@#The polymorphism of rs116855232 in NUDT15 gene was associated with hepatotoxicity induced by 6-mercaptopurine in children with ALL, and ALL patients with TT genotype should take a lower dose of 6-MP to avoided hepatotoxicity.

Objective:To discuss the treatment and prognosis of children with torsion of inguinal cryptorchidism.Methods:Clinical data of 15 cases of inguinal cryptorchidism with testicular torsion admitted to Beijing Children's Hospital from October 2015 to February 2019 were retrospectively analyzed. The average age of onset was 5.1 years (4 months-17 years). The clinical manifestations included inguinal swelling and pain in 13 cases, abdominal pain in 1 case and abdominal pain with vomiting in 1 case. The average duration of symptoms (up to the time of surgery) was 45.9 (5-170) h. Physical examination showed scrotal voided on affected side, groin swelling with tenderness. Lesions were found in 12 cases on the left and 3 cases on the right. Groin color Doppler ultrasound examination showed testis enlargement, uneven echo, decrease or disappearance of blood flow signal, suspected testicular torsion. Clinical diagnosis was inguinal cryptorchidism testicular torsion. Inguinal canal testicular exploration under general anesthesia. During the operation, the testicle was dark and twisted with an average torsion of 600°(180°-1 080°). Testicular activity was observed after exposure and reduction and torsion. After reduction, testicular color was immediately restored in 5 cases. After cutting open the white membrane of the testicular, there was blood outflow. In 2 cases, the testis was found to be inactive during the operation, but the parents requested to retain the testis and performed orchiopexy. 8 cases underwent orchiectomy due to necrosis of testis. The mean symptom duration (up to the time of operation) of the orchiectomy group and the orchiectomy group was 24.3 (5-73) h and 64.8 (7-170) h, respectively. The average torsion degree was 514° and 675°, respectively.Results:The average operative time of 15 patients was 56.7 min (40-85 min). Intraoperative blood loss averaged 1.5 (1-2) ml. There were no complications during and after operation. Postoperative follow-up averaged 27 (8-47) months. Among the 7 patients in the orchiopexy group, 3 patients had atrophy of testis 7.3 months after operation, and the remaining 4 patients had normal testis. In the orchiectomy group, 8 cases had normal contralateral testis without torsion.Conclusions:Inguinal cryptorchidism testicular torsion is a relatively rare disease in children. Color Doppler ultrasonography and inguinal canal exploration can help diagnosis and treatment. According to the condition of testis, orchiopexy or orchiectomy can be performed. Early diagnosis of this disease is difficult, easy to lead to testicular loss or postoperative atrophy.
RESUMO
Objective:To evaluate the effects of dexmedetomidine on the content of glutamate and expression of NR1 in hippocampus of mice with endotoxemia and the role of cholinergic anti-inflammatory pathway.Methods:Eighty clean-grade male C57BL/6 mice, aged 8 weeks, weighing 24-28 g, were divided into 4 groups ( n=20 each) using a random number table method: control group (group C), endotoxemia group (group LPS), dexmedetomidine group (group DEX) and alpha-bungarotoxin (α-BGT) group.Lipopolysaccharide 20 mg/kg was intraperitoneally injected to establish the model of endotoxemia in LPS, DEX and α-BGT groups. Dexmedetomidine 40 μg/kg was intraperitoneally at 15 min before establishing the model in DEX and α-BGT groups.In group α-BGT, alpha-7 nicotinic acetylcholine receptors specific agonist α-BGT 1 μg/kg was intraperitoneally injected at 15 min before injecting dexmedetomidine.Ten mice taken in each group were selected to collect the blood samples from the eyeball and then sacrificed, and hippocampi were isolated.Enzyme-linked immunosorbent assay was used to measure the concentration of serum S100β protein and NSE, and high-performance liquid chromatography was used to determine the content of glutamate in hippocampus.Ten mice in each group were sacrificed at 6 h after establishing the model to detect the expression of NR1 in hippocampus by immumofluorescence method. Results:Compared with group C, the concentrations of serum S100β protein and NSE concentrations and hippocampal glutamate content were significantly increased, and NR1 expression was up-regulated in LPS, DEX and α-BGT groups ( P<0.01). Compared with group LPS, the concentrations of serum S100β protein and NSE concentrations and hippocampal glutamate content were significantly decreased, and NR1 expression was down-regulated in DEX and α-BGT groups ( P<0.01). Compared with group DEX, the concentrations of serum S100β protein and NSE concentrations and hippocampal glutamate content were significantly increased, and NR1 expression was up-regulated in group α-BGT ( P<0.01). Conclusion:The mechanism by which dexmedetomidine alleviates cerebral injury is associated with activating cholinergic anti-inflammatory pathway, decreasing glutamate content and down-regulating NR1 expression in mice with endotoxemia.
