OBJECTIVE: To explore the predictive value of acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA), quick sequential organ failure assessment (qSOFA) and modified early warning score (MEWS) in evaluating the prognosis of patients in intensive care unit (ICU) of secondary hospitals, and to provide guidance for clinical application. METHODS: The clinical data of adult critical patients admitted to the ICU of Wanzhou District First People's Hospital from October 2022 to April 2023 were retrospectively analyzed. According to the clinical outcome of ICU, the patients were divided into improvement group and death group. The general information, blood routine, heart, liver and kidney function indicators, coagulation indicators, blood gas analysis, APACHE II score, SOFA score, qSOFA score, MEWS score at the time of admission to the ICU, the number of cases of invasive mechanical ventilation (IMV) and continuous blood purification (CBP) were compared between the two groups. Univariate analysis was performed, and multivariate Logistic regression analysis was used to analyze the related factors of death. Receiver operator characteristic curve (ROC curve) was used to analyze the predictive value of the four scores in ICU patients. RESULTS: A total of 126 patients were included, of which 45 patients died in the ICU and 81 patients improved and transferred out. Univariate analysis of death-related critically ill patients showed that procalcitonin (PCT), serum creatinine (SCr), blood urea nitrogen (BUN), albumin (ALB), prothrombin time (PT), activated partial prothrombin time (APTT), D-dimer, pH value, HCO₃^-, blood lactic acid (Lac), number of patients treated with IMV and CBP, APACHE II score, SOFA score, qSOFA score and MEWS score were significantly different between the two groups (all P < 0.05). Multivariate Logistic regression analysis showed that the APACHE II score [odds ratio (OR) = 1.115, 95% confidence interval (95%CI) was 1.025-1.213, P = 0.011], SOFA score (OR = 1.204, 95%CI was 1.037-1.398, P = 0.015), MEWS score (OR = 1.464, 95%CI was 1.102-1.946, P = 0.009), and APTT (OR = 1.081, 95%CI was 1.015-1.152, P = 0.016) were independent risk factors affecting the mortality of critically ill patients in the ICU. ROC curve analysis showed that APACHE II, SOFA, qSOFA, and MEWS scores could predict the prognosis of critically ill ICU patients, among which SOFA score had the strongest predictive effect, and the area under the curve (AUC) was 0.808. There was a statistically significant difference in the time required for the four scores (F = 117.333, P < 0.001), among which the MEWS scoring required the shortest time [(1.03±0.39) minutes], and the APACHE II scoring required the longest time [(2.81±1.04) minutes]. CONCLUSIONS APACHE II, SOFA, qSOFA, and MEWS scores can be used to assess the severity of critically ill patients and predict in-hospital mortality. The SOFA score is superior to other scores in predicting severity. The MEWS is preferred because its assessment time is shortest. Early warning score can help secondary hospitals to detect potentially critical patients early and provide help for clinical rapid urgent emergency decision-making.

Objective:To summarize the clinical characteristics of single-center children with low and intermediate-risk neuroblastoma (NB), report the long-term follow-up results of the growth and survival quality, and provide a basis for further clinical research.Methods:Clinical characteristics, including the sex, age, stage, risk of disease, and metastatic site of 370 newly treated children with low and intermediate-risk NB admitted to Hematology Oncology Center, Beijing Children′s Hospital from March 2007 to June 2019 were retrospectively analyzed.Kaplan-Meier method was used for survival analysis.WHO Anthro Plus was used for calculating Z score.Results:A total of 370 eligible children with low and intermediate-risk NB were included, with the mean age at onset of 16.8 months (1-191 months). Among them, 148 cases (40%) were younger than 12 months old.Mediastinal region was the most common primary site of NB (47.8%, 177 cases), followed by retroperitoneum/adrenal gland (41.4%, 153 cases). The median follow-up time of 370 patients was 31 months (0.3-157.0 months), the 5-years event free survival (EFS) and 5-year overall survival (OS) were 86.2% and 96.9%, respectively.Thirty-seven cases had growth and deve-lopment problems, of which 22 cases had stunted growth, 6 cases had low body mass, 9 cases had wasting, and 7.3%(27/370 cases) had scoliosis.5.5% of them had heart damage and 5.0%(18/357 cases) had kidney damage, involving 12 cases related to the primary tumor and 6 cases were surgically related.30.2%(95/315 cases) of them had hair changed after chemotherapy, and curly hair was the most common change.Compared with before treatment, 14.9% of the children had a personality change, with an impatient being the most common.Conclusions:The 5-year overall survival rate of the single-center large sample of low and intermediate-risk NB was high, mediastinal was the most common primary site of tumor, and the long-term quality of life is good, but there were still treatment-related side effects, and further clinical monitoring and long-term follow-up were needed.

Digestive tract reconstruction with side-to-side esophagojejunostomy is one of the most commonly used digestive tract reconstruction methods after laparoscopic total gastrectomy. It does not need an auxiliary incision. The linear stapler is used to directly enter the abdominal cavity through the Trocar to perform side-to-side anastomosis of esophagojejunostomy. The common hole can be closed by hand suture or linear stapler. 4K laparoscopy can present a clearer and more realistic view to the operators, so as to realize side-to-side esophagojejunostomy more accurately, to reduce the postoperative anastomo-tic related complications and improve the safety of the operation. This article will elaborate the technical key points and difficulties of esophagojejunostomy in 4K laparoscopic total gastrectomy, as well as the prevention and treatment of anastomotic related complications.

Laparoscopic radical surgery for rectal can-cer involves total mesorectal excision (TME), D 3 lymphadenectomy, and pelvic autonomic nerve preservation, the goal of which is trying to achieve completely radical cure for cancer and urogenital function preservation. In the actual operation procedure, the understanding of fascial anatomy in abdominal and pelvic cavity will help us to improve the quality of TME surgery for rectal cancer and to preserve the pelvic autonomic nerves. When entering the pelvic cavity, the identification of fascia propria of mesorectum, visceral fascia, pre-hypogastric nerve fascia, presacral fascia, ligament structures around the rectum and the Denonvilliers′ fascia in front of the rectum will help us to protect the pelvic autonomic nerves and avoid surgical injury. So the authors focus on how to identify the pelvic fascia structure clearly in laparoscopic radical resection for rectal cancer, furthermore, to master the concepts of fascia anatomy to realize TME for rectal cancer and to achieve pelvic autonomic nerve preservation.

Objective:To investigate the protective effect and mechanism of low-intensity pulsed ultrasound on human periodontal ligament stem cells (hPDLSCs) injured by high glucose.Methods:hPDLSCs were cultured in vitro and randomly divided into normal control group, high glucose model group and three low intensity pulsed ultrasound groups (30, 60, 90 mW/cm 2). Cells in the high glucose model group and three low intensity pulsed ultrasound groups were treated with high glucose medium (glucose 40 mmol/L) for 48 h to establish high glucose model. Cells in the normal control group were treated with normal medium (glucose 11 mmol/L). After modeling, three low intensity pulsed ultrasound groups were treated with low-frequency pulse for 20 min each day for 7 days at a dose of 30, 60 and 90 mW/cm 2 respectively. After 7 days, the proliferation ability of each group was determined by MTT assay. The changes of cell cycle and apoptosis were detected by flow cytometry. The level of Caspase-3, Caspase-6, and Caspase-9 was detected by colorimetry. The levels of Wnt1, Wnt10b and β-catenin genes and proteins were detected by reverse transcription PCR and Western Blot respectively. Results:Compared with the hPDLSCs in the normal control group, the hPDLSCs in the high glucose model group have the following changes except for the cell cycles (all P>0.05), i.e. the activity of the cells was decreased and the apoptosis was increased (all P<0.05), the activities of Caspase-3, Caspase-6, and Caspase-9 were increased (all P<0.05), and the expressions of Wnt1, Wnt10b and β-catenin genes and proteins were decreased (all P<0.05). Compared with the hPDLSCs in the high glucose model group, the hPDLSCs in low-intensity pulsed ultrasound groups have the following changes expect for the cell cycles (all P>0.05), i.e. cell viabilities were increased (all P<0.05), proliferation abilities were increased (all P<0.05), apoptosis rates were decreased (all P<0.05), the activities of Caspase-3, Caspase-6, Caspase-9 were decreased (all P<0.05), and the expressions of Wnt1, Wnt10b and β-catenin genes and proteins were up-regulated ( P<0.05). Among the three low-intensity pulsed ultrasound groups, when the ultrasonic intensity is 90 mW/cm 2, the above-mentioned index changes most obviously (all P<0.05). Conclusions:Low-intensity pulsed ultrasound can significantly alleviate the hPDLSCs damage induced by high glucose, which may be achieved by reducing the activities of Caspase-3, Caspase-6 and Caspase-9, and up-regulating the expression of Wnt1, Wnt10b and β-catenin.

Objective:To summarize the clinical features, treatment and outcomes of cervical neuroblastoma (NB) subjected to multi-disciplinary treatment.Methods:The clinical features of cervical NB patients who were admitted to Beijing Children′s Hospital, Capital Medical University from February 2015 to October 2018, were retrospectively analyzed.The tumor makers [lactate dehydrogenase(LDH), neuron-specific enolase(NSE), urine homovanillic acid/creatinine(HVA/Crn), and urine vanillyl-mandelic acid/creatinine(VMA/Crn)], index of tumor burden(KTB), bone marrow examination, histopathologic types, N- MYC, gene amplification and 11q23 depletion type, staging and grouping, treatment and outcomes were analyzed.Follow-up was ended on March 31 st, 2019. Results:The 13 cervical NB patients aged from 1 month to 47 months (median age: 10 months), and 8 patients (61.5%) were younger than 18 months old.The course of disease ranged from 0.5 to 24.0 months (median course: more than 1 month). Seven patients (53.8%) presented with cervical masses.According to International Neuroblastoma Staging System (INSS), 8 patients (61.5%) were identified as stage Ⅱ, 3 patients (23.1%) as stage Ⅲ, and 2 patients (15.4%) as stage Ⅳ.There were 8 patients (61.1%) at low risk, 4 patients (30.8%) at intermediate risk, 1 patient (7.7%) at high risk.As for the laboratory examinations, LDH was increased in 7 patients (53.8%), and normal in 5 patients (38.5%). NSE was increased in 9 patients (69.2%), and normal in 4 patients (30.8%). Urine VMA/Crn was increased in 5 patients (38.5%), and normal in 8 patients (61.5%). HVA/Crn was increased in 8 patients (61.5%), and normal in 5 patients (38.5%). KTB was increased in 5 patients (38.5%), and normal in 5 patients (38.5%). No NB cell was detected in bone marrow of 13 patients.The pathologic type was NB in 9 patients (69.2%), and ganglioneuroma in 4 patients (30.8%). N-MYC gene amplification and 11q depletion were not detected.All the 13 patients accepted regular chemotherapy, radiotherapy and primary tumor resection in accordance with the staging and clinical risk grouping.The range of follow-up time was 5 to 48 months (median: 24 months). All of the patients fi-nished their treatment and were followed up regularly.Nine patients (69.2%) achieved complete remission, 4 patients (30.8%) achieved partial remission, and none of the patients had progression of disease.Conclusions:Cervical NB subjected to multi-disciplinary treatment has a smaller age at admission, mostly presented with cervical masses and rarely accompanied with distant metastasis.They are mostly at low risk or intermediate risk, and can achieve good outcomes after regular treatment.

Objective:To summarize the clinical characteristics of high-risk neuroblastoma (HR-NB) in a single center, analyze the prognostic factors of HR-NB.Methods:The clinical data of children with HR-NB who were treated and followed up at the hematology-oncology center of Beijing Children′s Hospital from February 1, 2007 to June 30, 2018 were analyzed retrospectively. The clinical features were summarized. Kaplan-Meier method was used for survival analysis and Cox regression was used to analyze the prognostic factors. The last follow-up time was June 30, 2019.Results:A total of 458 children with HR-NB were enrolled in this study, including 265 males (57.9%) and 193 females (42.1%), the age at diagnosis was 40.0 months (4.5-148.0 months), the follow-up time was 22.0 months (0.2-138.0 months) and the time of tumor progression or recurrence was 15 months (1-72 months). The 5-year event-free survival (EFS) rate was (31.2±2.6)% and the 5-year overall survival (OS) rate was (43.9±3.2)%. The 5-year EFS rate and 5-year OS rate in 142 hematopoietic stem cell transplantation (HSCT) patients with bone marrow metastases were better than that in 196 non-transplantation cases with bone marrow metastases ((26.5±4.5)% vs. (25.1±3.6)%, χ2=13.773, P=0.001; (38.1±5.5)% vs. (35.7±4.7)%, χ2=9.235, P=0.002); 128 transplantation patients with bone metastases had higher 5-year EFS rate and 5-year OS rate than 188 non-transplantation cases with bone metastases ((28.5±5.0)% vs. (26.7±3.8)%, χ2=10.222, P=0.001; (37.1±6.0)% vs. (36.2±4.8)%, χ2=7.843, P=0.005). The 5-year EFS rate was higher in 37 HSCT patients with MYCN amplification than in 49 non-transplantation cases with MYCN amplification ((26.8±8.0) % vs. (20.5±6.4) %, χ2=5.732, P=0.017). No significant difference was found in 5-years OS rate between transplantation group with MYCN amplification and non-transplantation group with MYCN amplification ((31.4±8.6) % vs. (26.2±7.4) %, χ2=3.230, P=0.072). Univariate survival analysis showed that lactate dehydrogenase (LDH)≥1 500 U/L was associated with poor prognosis of patients with MYCN amplification (χ2=6.960, P=0.008). Multivariate Cox analysis showed bone marrow metastasis and LDH≥1 500 U/L were independent risk factors for poor prognosis of patients with non-MYCN amplification ( HR=2.427, 1.618;95 %CI：1.427-4.126, 1.275-2.054, P<0.05) for both comparisons. Conclusions:LDH≥1 500 U/L was the poor prognostic factor for patients with MYCN amplification. The bone marrow metastasis and LDH≥1 500 U/L were the poor prognostic factors for HR-NB patients with non-MYCN amplification. HSCT can improve the prognosis of patients with bone or bone marrow metastasis. It can also retard the time of progression or recurrence for patients with MYCN amplification.

Single-port and reduced-port laparoscopic radical gastrectomy as the innovative surgery for gastric cancer are gradually accepted nowadays,and more attentions are also paid to single-port and reduced-port laparoscopic radical gastrectomy due to its better cosmetic effect,less pain,lower incidence rate of surgical site infection and more advantages in enhanced recovery after surgery.However,in the early stage,the development of single-port and reduced-port laparoscopic radical gastrectomy were facing challenges and obstacles on account of limited surgical skills,the lack of special laparoscopic instruments,laparoscope and multi-port Trocar.In recent years,the dilemma and difficult situations were gradually resolved following by surgical techniques innovation,laparoscopic instruments and facilities improvement.It is believed that single-port and reduced-port laparoscopic radical gastrectomy will have a good prospect and breakthrough in the field of gastric cancer treatment in the future.
