In order to explore the application value of the suction connecting tube combined with gastroscope visual blood clot removal device in the blood clot removal surgery of patients with upper gastrointestinal bleeding, the clinical data of 18 patients with upper gastrointestinal bleeding treated with this device at the Department of Gastroenterology, General Hospital of Central Theater Command from January 2023 to June 2024 were retrospectively analyzed to observe its therapeutic effect. The results showed that the operation time of the device for 18 patients ranged 4-16 minutes (8.2±3.1 min). The total volume of blood clots and blood cleared ranged 120-500 mL (221.1±97.1 mL). Blood and blood clots were successfully removed in a single procedure in 17 patients, with a success rate of 94.4% (17/18). Hemostasis was unsuccessful in 1 patient with gastric cancer and bleeding under endoscopy, and subsequent surgical treatment was performed. No serious complication occurred. The suction connecting tube combined with gastroscope visual blood clot removal device can effectively remove blood and blood clots in the digestive tract, with high success rate, which is worth promotion and application.

Objective:To explore the early predictive value of the triglyceride-glucose (TyG) index and the controlling nutritional status (CONUT) score for severe acute pancreatitis (SAP).Methods:Clinical data from 1 050 hospitalized patients with acute pancreatitis (AP) at the General Hospital of Central Theater Command between January 2019 and December 2023 were retrospectively analyzed. Patients were categorized into mild acute pancreatitis (MAP) group ( n=606), moderately severe acute pancreatitis (MSAP) group ( n=320), and SAP group ( n=124) based on AP severity. General clinical data, laboratory parameters, modified computed tomography severity index (MCTSI), bedside index for severity in acute pancreatitis (BISAP), TyG index, and CONUT score were compared among the three groups. Spearman correlation analysis was used to evaluate the relationship between TyG index, CONUT score and AP severity. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for AP severity. Receiver operating characteristic curves (ROC) were plotted to calculate the area under the curve (AUC), sensitivity, and specificity for evaluating the predictive efficacy of TyG index, CONUT score, and their combination for SAP. Results:Significant differences on TyG index and CONUT score were observed among AP patients with varying severity (all P value <0.001). Spearman correlation analysis further revealed positive correlations of TyG index ( r=0.174), CONUT score ( r=0.306) with AP severity (both P<0.001). Multivariate logistic regression identified neutrophil count ( OR=1.076, 95% CI 1.027-1.125), MCTSI ( OR=2.565, 95% CI 2.250-2.921), BISAP ( OR=3.522, 95% CI 2.726-4.549), TyG index ( OR=1.859, 95% CI 1.276-2.707), and CONUT score ( OR=1.155, 95% CI 1.035-1.288) as independent risk factors for AP severity. The combined predictive model equation was: -7.342+0.76×TyG+0.439×CONUT. ROC analysis showed that the AUC values of the TyG index, CONUT score, and the combined index (TyG index+CONUT score) were 0.583 (95% CI 0.529-0.637), 0.701 (95% CI 0.652-0.75), and 0.755 (95% CI 0.710-0.801), with sensitivities of 0.706, 0.677, and 0.742, and specificities of 0.884, 0.629, and 0.657, respectively (all P value <0.05). Conclusions:TyG index and CONUT score are positively correlated with AP severity and may serve as reliable predictors for SAP. Their combination could enhance the predictive accuracy for AP.

Objective To investigate the imaging findings of craniocervical adenoid cystic carcinoma(ACC)with invading adjacent tissues,neural foramen and tube.Methods The CT and MR imaging features of 33 cases of craniocervical ACC with invading adja-cent tissues,neural foramen and tube of the basis cranii were analyzed retrospectively and compared with surgical and pathological results.Results Among 33 cases of ACC,17 cases were located in the nasal cavity,sinuses and nasopharynx(including 3 cases of recur-rence after surgery),8 cases in salivary gland,5 cases in lacrimal gland and lacrimal sac,and 3 cases in external auditory canal.Tumors invaded and destroyed adjacent muscle bundles,spaces,nasal cavity,sinuses,and bone walls in 16 cases,invaded pterygopala-tine fossa in 9 cases,pterygoid canal in 7 cases,foramen rotundum in 6 cases,foramen ovale in 5 cases,nasolacrimal duct in 3 cases,foramina stylomastoideum in 2 cases and external auditory canal in 3 cases(a total of 35 foramen and tubes).When the tumor inva-ded the adjacent muscle bundles,spaces,nasal cavity,sinuses and basis cranii,CT or MR showed the thickening of the surrounding tissues,with the density/signal abnormalities and obvious enhancement.When the tumor invaded the adjacent bone,cartilage,neural foramen and tube,CT displayed the thickening,thinning,or loss of the bone wall,as well as the enlargement of neural foramen and tube,wall thickening,and bone destruction.Conclusion CT and MR can show the imaging features of multiple small vesicles and ethmoid structures in the craniocervical ACC,as well as the invasion of adjacent tissues and the destruction of basis cranii,maxillofa-cial nerve foramen and tube,which are of great significance for the imaging diagnosis and surgical treatment of craniocervical ACC.

Objective:To study the feasibility and efficacy of pericranial flaps for the repairs of large anterior skull base defects.Methods:The average length of the pericranial flaps needed for skull base repair was determined with computed tomography measurements in 20 adults and anatomical dissections in 5 cadaver specimen. A series of patients who underwent endoscopic skull base surgeries and subsequent reconstructions with pericranial flaps at the Department of Otolaryngology Head and Neck Surgery, Shanghai Jiao Tong University School of Medicine Affiliated Sixth People′s Hospital from 2016 to 2022 were retrospectively reviewed. There were 19 males and 6 females, aged from 11 to 59 years, including 13 cases of cerebrospinal fluid (CSF) rhinorrhea (12 traumatic) and 12 cases of sinonasal skull base tumors. Descriptive statistical methods were used.Results:The mean areas of anterior skull base, sellar, and clival defects were 16.13, 14.03 and 13.12 cm 2, respectively, and the mean pericranial flap lengths were (18.77±3.44)mm, (133.99±5.08)mm, (181.76±6.31)mm, respectively. Among sinonasal skull base neoplasms, the pathologies included olfactory neuroblastoma ( n=6), squamous cell carcinoma ( n=3), chondrosarcoma ( n=1), osteosarcoma ( n=1), and invasive schwannoma ( n=1), in whom 8 patients underwent adjuvant radiotherapy after surgery. One patient (7.7%) had acoustic neuroma-related CSF leak before radiotherapy. All 25 patients successfully underwent skull base reconstruction without complications such as CSF leak, intracranial infection, forehead wrinkles disappearance, or scalp necrosis. All flaps survived well with no CSF leaks within the follow-up period of 2-4 years. Conclusion:Pericranial flap is a safe choice for large anterior skull base defects following resection of sinonasal skull base neoplasms and complex traumatic CSF leaks when endonasal flaps are not available.

Objective To investigate the correlation between atherogenic index of plasma (AIP) and the severity of hypertriglyceridemic acute pancreatitis (HTG-AP) and the value of AIP combined with Bedside Index for Severity in Acute Pancreatitis (BISAP) score in the early prediction of severe HTG-AP (sHTG-AP). Methods A retrospective analysis was performed for the clinical data of 170 patients with HTG-AP who were hospitalized in The General Hospital of Central Theater Command from January 2017 to December 2021, and according to related guidelines, they were divided into the sHTG-AP group with 28 patients and non-sHTG-AP group with 142 patients. Peripheral blood samples were collected from all patients within 24 hours after admission, and the two groups were compared in terms of sex, age, laboratory test results, AIP, BISAP score, and modified CT severity index (MCTSI) score. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups; the Mann-Whitney U test was used for comparison of continuous data between groups. The Spearman rank correlation test was used to investigate the correlation between each factor and the severity of HTG-AP, and the binary logistic regression analysis were used to investigate the independent risk factors for sHTG-AP. The receiver operating characteristic (ROC) curve was plotted to assess the predictive efficacy of each indicator. Results There were significant differences between the two groups in the medical history of diabetes, lymphocyte count, albumin, Ca 2+ , triglyceride, high-density lipoprotein cholesterol, AIP, BISAP score, MCTSI score, length of hospital stay, and hospital costs (all P < 0.05). The sHTG-AP group had a longer length of hospital stay, higher hospital costs, and a higher AIP value. AIP (odds ratio [ OR ]=1.244, 95% confidence interval [ CI ]: 1.062-1.458, P =0.007), BISAP score ( OR =5.525, 95% CI : 1.646-18.543, P =0.006), and MCTSI score ( OR =2.029, 95% CI : 1.245-3.305, P =0.004) were risk factors for sHTG-AP. AIP, BISAP score, and MCTSI score were positively correlated with the severity of HTG-AP ( r =0.291, 0.631, and 0.649, all P < 0.001), and AIP was positively correlated with BISAP score and MCTSI score ( r =0.190 and 0.215, both P < 0.05). AIP had an optimal cut-off value of 1.095 in predicting sHTG-AP, and AIP, BISAP score, and AIP combined with BISAP score had an area under the ROC curve of 0.759, 0.887, 0.925, respectively, a sensitivity of 0.821, 0.857, and 0.786, respectively, and a specificity of 0.627, 0.817, and 0.937, respectively (all P < 0.001). Conclusion AIP is a risk factor for sHTG-AP and is correlated with disease severity, and AIP combined with BISAP score has a relatively high value in the early prediction of sHTG-AP.

Hyaluronic acid (HA) injections have already been one of most popular cosmetic procedures for around 18 years. However, blindness is one of the most serious complications caused by HA injections. There is still no consensus on the treatment for vision recovery. The efficacy and safety of different delivery administration of hyaluronidase such as retrobulbar injection and endovascular intervention are still controversial so far. Based on current status, prevention is prior to treatment, which is widely recognized in the world. The pathogenic mechanism of blindness induced by filler injection is still not clear, and there exist several theories including the artery embolism, ischaemia, artery spasm and venous involvement, which are all related to the ophthalmic artery and its branches. Therefore, acquiring anatomic knowledge and the relevant parameters will help us prevent to damage the ophthalmic artery and its branches during HA injections. The mechanism, treatment progress and prognosis of blindness caused by HA injections in recent years were analyzed and summarized in this article. We hope it will help the clinician to improve the relevant knowledge about vision loss caused by HA injection, as well as to promote the safety of filler injection.
