RESUMEN
ObjectiveTo evaluate the efficacy and safety of first-line transcatheter arterial chemoembolization （TACE） combined with targeted therapy and immunotherapy in the treatment of patients with stage Ⅱb/Ⅲa hepatocellular carcinoma （HCC） based on China Liver Cancer Staging （CNLC）. MethodsA total of 198 patients who received first-line TACE combined with targeted therapy and immunotherapy or received TACE alone from January 2015 to December 2022 in the First Affiliated Hospital of Soochow University were enrolled in this study， and after propensity score matching， there were 50 patients in combination group and 50 patients in TACE group. The Kaplan-Meier method was used to calculate median overall survival （mOS） and median progression-free survival （mPFS）. Modified Response Evaluation Criteria in Solid Tumors was used to evaluate objective response rate （ORR） and disease control rate （DCR）， and Common Terminology Criteria for Adverse Events v5.0 was used to evaluate adverse events. The chi-square test was used for comparison of categorical data between two groups； the t-test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups. The Kaplan-Meier method was used to estimate survival time and calculate 95% confidence interval （CI）， and the Log-rank test was used for comparison of mOS and mPFS between two groups. ResultsThe combination group had an mOS of 30.1 months （95%CI： 21.9 — 38.3）， and the TACE group had an mOS of 14.5 months （95%CI： 11.0 — 18.0）， with a significant difference between the two groups （χ2=17.8， P<0.001）； the combination group had an mPFS of 10.3 months （95%CI： 8.8 — 11.8）， and the TACE group had an mPFS of 7.1 months （95%CI： 5.8 — 8.4）， with a significant difference between the two groups （χ2=10.4， P<0.001）. There were significant differences between the combination group and the TACE group in ORR （84% vs 58%， P<0.05） and DCR （94% vs 80%， P<0.05）. There was no significant difference between the combination group and the TACE group in the incidence rate of adverse events （24% vs 16%， P=0.317）， and no adverse event-related deaths were observed in either group. ConclusionCompared with TACE alone， TACE combined with targeted therapy and immunotherapy has a better efficacy in the treatment of patients with CNLC stage Ⅱb/Ⅲa HCC， without increasing the incidence rate of severe adverse events.
RESUMEN
Objective To investigate the protective and treatment role of ulinastatin(UTI)on con-trast-induced acute kidney injury(CIAKI)in the elderly with coronary heart disease(CHD)and chronic kidney diseases(CKD).Methods A total of 321 elderly CHD inpatients complicated with CKD undergoing coronary angiography admitted in the First Medical Center of Chinese PLA Gen-eral Hospital from November 2021 to November 2022 were enrolled consecutively and then divid-ed into UTI group(n=161)and hydration group(n=160).Their cardiac and renal function pa-rameters were collected and analyzed before and 2 d after intervention.The changes in above pa-rameters and incidence of CIAK were observed and compared between the two groups.Results In 2 d after intervention,the UTI group had significantly lower Scr,urea,CysC,homocysteine and NT-proBNP,but higher eGFR than the hydration group(P＜0.01).There were 62 patients(62/321,19.3％)developing CIAKI,including 17 from the UTI group and 45 from the hydration group,and statistical difference was observed in the incidence(10.6％vs 28.1％,P＜0.01).For the patients with comorbidities of hypertension,diabetes,hyperlipidemia and hyperuricemia,the incidence of CIAKI was obviously lower in the UTI group than the hydration group(P＜0.01).Multivariate logistic regression analysis showed that UTI was an independent protective factor for occurrence of CIAKI(OR=0.348,95％CI:0.180-0.673,P=0.001).Conclusion UTI can im-prove renal function and reduce the risk of CIAKI in elderly CHD patients with CKD.

RESUMEN
Intrahepatic cholangiocarcinoma （ICC） is a relatively rare type of primary liver cancer， and its incidence rate has gradually increased in recent years. Due to its insidious onset and atypical clinical symptoms， most patients are already in the advanced stage of the disease at the time of confirmed diagnosis， and therefore， timely diagnosis and treatment are of great importance. Radical surgical resection is the standard treatment regimen for early-stage ICC patients， while systemic chemotherapy is the basic treatment for patients with advanced ICC and is often combined with interventional treatment， targeted therapy， and immunotherapy. This article reviews the advances in the diagnosis and treatment of ICC.

RESUMEN
Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure to establish a portosystemic shunt between the hepatic vein and the portal vein via the jugular approach, so as to reduce portal venous pressure and control acute esophagogastric variceal bleeding (EGVB). The prognosis of EGVB has been improved significantly over the past few decades, and endoscopic variceal ligation combined with drug therapy is now recommended as the first-line treatment regimen for this disease. The latest research advances in the management of EGVB over the past decade have focused on the relatively new concept of "early" or "pre-emptive" TIPS, that is to say, early TIPS (within 72 hours after admission, ideally within 24 hours) is recommended for patients with EGVB who are at a relatively high risk of failure in standard treatment. This article briefly introduces the effect of early TIPS on controlling bleeding, mortality rate, and hepatic encephalopathy, the high-risk population for early TIPS, timing of intervention, cost effectiveness, the applications of early TIPS in a real-world setting, and recommendations for early TIPS in international guidelines and consensus statements.
RESUMEN
A pharmacophore-based study was conducted to investigate the therapeutic activity of the traditional Tibetan medicine Zha Xun (ZX) in liver diseases. In the present study, the protective effect of ZX on the acute liver injury induced by concanavalin A (ConA) and 0.15% carbon tetrachloride (0.15% CCl4) in ICR mice was evaluated, and the results showed that ZX significantly reduced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the ConA-induced acute immune liver injury model and the CCl4-induced acute oxidative liver injury model (P < 0.05). Subsequently, the protective effects of aqueous, 95% ethanol, 60% ethanol and 30% ethanol eluting fractions of ZX, and fulvic acid, the main water-soluble constituent of ZX, were evaluated against acute oxidative liver injury induced by 0.15% CCl4 in mice. The results showed that different solvent-eluting fractions of ZX showed certain hepatoprotective activities, among which the aqueous extract of ZX and 30% ethanol extract of ZX significantly reduced the serum levels of ALT, AST, and lactate dehydrogenase (LDH) in mice (P < 0.05), and the serum levels of LDH in mice were significantly reduced by fulvic acid (P < 0.05), which showed significant hepatoprotective activity. The protective activities and preliminary mechanisms of the total extract of ZX, the aqueous extract of ZX, the 30% ethanol extract of ZX, and fulvic acid against hepatocellular injury in vitro were further evaluated by using the H2O2-induced hepatocellular injury model. The results showed that the components could significantly inhibit H2O2-induced hepatocellular injury, reduce the levels of ALT, alkaline phosphatase (ALP), and LDH, improve the survival rate of hepatocellular cells, and reduce the content of intracellular reactive oxygen species (ROS) in cell culture. At the same time, it can inhibit hepatocyte apoptosis by increasing the expression ratio of Bcl-2/BAX protein and decreasing the expression ratio of cleaved caspase-3/pro caspase-3 protein. The present study showed that ZX has clear hepatoprotective activity in vitro and in vivo, and the different solvent elution fractions of ZX showed certain hepatoprotective activity, among which the aqueous extract of ZX, 30% ethanol extract of ZX had better hepatoprotective activity, and the activity of 60% ethanol extract of ZX was stronger than that of 95% ethanol extract of ZX. The activity of ZX and its water-soluble elution site exerted hepatoprotective effects by inhibiting hepatocyte apoptosis and oxidative stress. The animals used in this experiment and related disposal meet the requirements of animal welfare, and have been reviewed and approved by the Laboratory Animal Management and Use Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences (approval number: 00004018).
RESUMEN
Surgical resection in patients with advanced primary carcinoma of liver has high risks of early recurrence and incidence of portal vein tumor thrombus, caused by insufficient resi-dual liver volume after two-steps hepatotomy. At present, the treatment for patients with advanced primary carcinoma of liver is limited, thus can't satisfy the requirement of patient for treatment. The authors introduce the clinical experience of a patient with hepatocellular carcinoma and insufficient residual liver volume who underwent preventive immunotherapy plus target therapy after associa-ting liver partition and portal vein ligation for staged hepatectomy, in order to provide reference for relevant treatment.
RESUMEN
There is a consensus that selectively perform splenic lymph node dissection is necessary for high-risk patients with proximal gastric cancer to achieve radical treatment. However, there are still some outstanding issues that need to be solved during the practice of splenic lymph node dissection. These include poorly defined boundaries, technical difficulties, and blurred boundaries in No. 10 and No. 11 lymph nodes, etc. Membrane anatomy has achieved successful applications in the field of gastric and colorectal surgery in recent years. The study of membrane anatomy in the splenic hilum region is controversial due to the special location of the splenic hilum, which involves multiple organs and affiliated mesentery undergoing complex rotation, folding, and fusion during embryonic development. In this manuscript, we summarize the following points based on existing research and personal experience regarding membrane anatomy. 1. There is a membrane anatomical structure that can be used for lymph node dissection in the splenic hilum region. 2. The membrane structure in the splenic hilum region can be divided into two layers: the superficial layer is composed of the dorsal mesogastrium, and the deep layer is composed of Gerota fascia, the tail of the pancreas, and the mesentery of the transverse colon (from head to tail). 3. There is a loose space between the two layers that can be used for separation during surgery. The resection of the dorsal mesogastrium belongs to D2 dissection. The No. 10 lymph node in the deeper layer belongs to the duodenal mesentery, and the resection of the No.10 lymph node exceeds D2 dissection. The complete excision of the gastric dorsal mesentery is consistent with the D2+CME surgical mode proposed by Gong Jianping's group.

Objective:To explore whether the simulation training system for transesophageal echocardiography (TEE) can improve the effectiveness of standardized training of resident anesthesiologists.Methods:A total of 72 resident anesthesiologists without experience in cardiac ultrasound were randomly divided into traditional teaching group (36 residents) and simulation training group (36 residents). Before and after the teaching, theoretical examinations of 5 knowledge points related to cardiac ultrasound were conducted. After a standardized rotation of 2 months, the students were re-examined for both theories and operations, and clinical indicators were recorded. SPSS 23.0 was used for the t-test, rank sum test, chi-square test, or Fisher's exact test. Results:There was no significant difference in scores of theoretical examinations between the two groups of students before teaching. After teaching, the scores of the simulation training group were higher than those of the traditional teaching group, and the differences were significant in cross-sectional recognition and image diagnosis ( P<0.05). After rotation, there was no significant difference in theoretical examination between the two groups of students, but the score of operation was significantly higher in the simulation training group than in the traditional teaching group ( P<0.05). During the rotation period, the incidence of TEE-related complications was relatively low and the quantitative score of clinical operational skill assessment was relatively high in the simulation training group ( P<0.05). Conclusion:Anesthesia residents who receive training with the simulation system before TEE training can quickly acquire operational skills, reduce related complications, and more accurately identify and obtain standard TEE sections, which has significant value for clinical teaching.
RESUMEN
OBJECTIVE To evaluate the cost-effectiveness of nivolumab combined with ipilimumab in the first-line treatment of unresectable malignant pleural mesothelioma （MPM）. METHODS From the perspective of healthcare system ，a partitioned survival model were developed ，the cost-effectiveness of nivolumab combined with ipilimumab （dual-immunotherapy plan ）versus chemotherapy in the first-line treatment of unresectable MPM by cost-utility analysis. Clinical trial data were collected from CheckMate 743 study. Direct medical cost included drug costs ，disease management cost and cost of treatment of adverse reactions. Costs and utilities were discounted at an annual rate of 5％. The willingness to pay threshold was 3 times of gross domestic product （GDP）per capita in 2021 [242 928 yuan/QALY（quality-adjusted life year ）]. Scenario analysis was used to analyze and compare the two regimens under the scenario of complimentary drug for patients in dual-immunotherapy group. The robustness of the findings was evaluated by one-way sensitivity analysis and probabilistic sensitivity analysis. RESULTS Baseline analysis results showed that total cost of dual-immunotherapy regimen was higher than that of chemotherapy regimen ，and the utility was also better than that of chemotherapy plan ；the incremental cost-effectiveness ratio （ICER）was 417 122.2 yuan/QALY，which was higher than the willingness to pay threshold ；the dual-immunotherapy regimen was not cost-effective compared to the chemotherapy regimen. Under the scenario of complimentary drug ，the cost of dual-immunotherapy was 327 454.5 yuan，ICER was 75 664.1 yuan/QALY，which was lower than the willingness to pay threshold and resulted in a reversal of the baseline analysis. One-way sensitivity analysis showed that under the health states of progression free survival and progressive disease ，utility value and the price of nivolumab had a greater impact on the ICER value. Probabilistic sensitivity analysis showed that the results of baseline analysis were robust. CONCLUSIONS At a 163.com willingness to pay threshold of 3 times of GDP per capita in nivolumab combined with ipilimumab is not cost-effective compared with chemotherapy regimen in the first-line treatment of unresectable MPM. However ，if patients receive complimentary drugs ，the dual-immunotherapy regimen is cost-effective.

Methods: Seventy-two kids with diarrhea of damp-heat pattern were recruited and divided into a high-dosage group and a low-dosage group using the random number table method, with 36 cases in each group. They all received conventional antidiarrheal treatment and umbilical application with herbal cakes. However, the herbal cakes for the high-dosage group were made of the mixture of Ge Gen Qin Lian Tang powder and water, and those for the low-dosage group consisted of 10％ Ge Gen Qin Lian Tang powder and 90％ auxiliary materials (corn starch) plus water. The treatment duration was 3 d. The clinical efficacy, antidiarrheal rate, effective rate for symptoms and signs of traditional Chinese medicine (TCM), TCM symptoms score, and safety indicators were compared between the two groups. Results: After the treatment, the TCM symptoms scores dropped significantly in both groups (P<0.01) and were lower in the high-dosage group than in the low-dosage group (P<0.05). The clinical efficacy was more significant in the high-dosage group than in the low-dosage group after the treatment, and the between-group difference was statistically significant (P<0.05); the antidiarrheal rate was markedly higher in the high-dosage group than in the low-dosage group (P<0.05). Regarding the TCM symptoms and signs, the high-dosage group showed better results in improving the greasy and yellowish tongue coating, bowel movement frequency, watery excrement, short and dark urine, red tongue body, red anus, vomiting, bowel sounds, and abdominal bloating compared with the low-dosage group, and the between-group differences were statistically significant (P<0.01). Conclusion: Umbilical therapy with herbal cakes made of Ge Gen Qin Lian Tang is safe, reliable, and effective in treating damp-heat diarrhea in young children; the high-dosage herbal cakes produce more significant efficacy than the low-dosage ones and are worth further investigation.
RESUMEN
It is extremely dangerous to treat the posterior third of the superior sagittal sinus (PTSSS) surgically, since it is usually not completely ligated. In this report, the authors described the case of a 27-year-old man with a ruptured and defective PTSSS caused by an open depressed skull fracture, which was treated by ligation of the PTSSS and the patient achieved a positive recovery. The patient's occiput was hit by a height-limiting rod and was in a mild coma. A CT scan showed an open depressed skull fracture overlying the PTSSS and a diffuse brain swelling. He underwent emergency surgery. When the skull fragments were removed, a 4 cm segment of the superior sagittal sinus (SSS) and the adjacent dura mater were removed together with bone fragments. Haemorrhage occurred and blood pressure dropped. We completed the operation by ligating the severed ends of the fractured sagittal sinus. One month after the operation, apart from visual field defects, he recovered well. In our opinion, in primary hospitals, when patients with severely injured PTSSS cannot sustain a long-time and complicated operation, e.g., the bypass using venous graft, and face life-threatening conditions, ligation of the PTSSS is another option, which may unexpectedly achieve good results.

RESUMEN
Objective:To analyze the relationship between blood electrolytes and the prognosis of patients with severe coronavirus disease 2019 (COVID-19) and to provide assistance for clinical decision-making.Methods:The clinical data of patients with severe COVID-19 admitted to intensive care unit (ICU) of the Wuhan Third Hospital by the Shanghai aid-Hubei medical team from January 21 to March 4, 2020 were collected. Excluding ineligible patients, 110 patients were finally enrolled. The patients' gender, age, temperature, heart rate, systolic and diastolic blood pressure, clinical symptoms at admission, time of symptom onset, duration of fever, and relevant indicators at admission to ICU (including blood potassium, chloride, sodium, calcium, phosphorus, and magnesium, etc.) and prognosis were analyzed. The patients were grouped by blood potassium or calcium levels or blood potassium/calcium ratio. The Kaplan-Meier survival curves were used to analyze the survival of patients in each group. The relationship between the potassium/calcium ratio and the prognosis was analyzed using restricted cubic spline plots. The relationship between each index in the different models and the prognosis was analyzed using Cox regression models.Results:Among 110 severe COVID-19 patients, 78 cases survived, and 32 cases died. Compared with the surviving group, patients in the death group had higher blood potassium levels [mmol/L: 4.25 (3.80, 4.65) vs. 3.90 (3.60, 4.20), P < 0.05] and lower blood calcium levels (mmol/L: 2.00±0.14 vs. 2.19±0.18, P < 0.05). The Kaplan-Meier survival curves showed that patients in the potassium > 4.2 mmol/L group had a worse prognosis than the potassium < 3.8 mmol/L group and the potassium 3.8-4.2 mmol/L group ( P = 0.011), patients in the calcium > 2.23 mmol/L group had a better prognosis than the calcium < 2.03 mmol/L group and the calcium 2.03-2.23 mmol/L group, and the lower calcium group had a worse prognosis ( P = 0.000 15). Cox regression analysis showed that the hazard ratio ( HR) of blood potassium and calcium were 2.08 and 0.01, respectively, in model 1 (single blood potassium or calcium) and in model 2 (model 1 plus age and gender), the HR of blood potassium and calcium were 1.98 and 0.01 respectively, which were significantly associated with patient prognosis (all P < 0.05). Patients in the group with the potassium/calcium ratio > 1.9 had higher blood potassium levels and a higher proportion of mechanical ventilation, lower calcium levels and lower proportion of survival, and longer time of ICU admission compared with the groups with the potassium/calcium ratio < 1.7 and 1.7-1.9. The Kaplan-Meier survival curves showed that the survival rate of the potassium/calcium ratio > 1.9 group was the lowest ( P < 0.000 1), and there was no statistically significant difference in survival between the potassium/calcium ratio < 1.7 group and the potassium/calcium ratio 1.7-1.9 group. A restricted cubic spline plot corrected for age and gender showed that patients in the potassium/calcium ratio > 1.8 group had HR values > 1. Cox regression analysis corrected for other indicators showed that the potassium/calcium ratio was still associated with patient prognosis ( HR = 4.85, P = 0.033). Conclusions:Blood potassium, calcium, and the potassium/calcium ratio at ICU admission are related to the prognosis of patients with severe COVID-19, and the potassium/calcium ratio is an independent risk factor for the death of patients. The higher the potassium/calcium ratio, the worse the prognosis of patients.

RESUMEN
BACKGROUND@#Lung cancer is the leading cause of death worldwide, and lung adenocarcinoma is the main subtype of lung cancer. DEP domain-containing 1 (DEPDC1) has been proved to be closely related to the occurrence and development of most tumors, and the overexpression of DEPDC1 in lung adenocarcinoma has been preliminarily confirmed. This study aims to explore the relationship between the expression of DEPDC1 and the clinical prognosis of lung adenocarcinoma, and to preliminarily explore the possibility of DEPDC1 as a potential biomarker and therapeutic target of lung adenocarcinoma.@*METHODS@#The bioinformatics website GEPIA database was used to collect relevant information, and the prognostic was analyzed online. Patient data were collected for statistical analysis, and immunohistochemical staining was performed on the collected samples. Subsequently, lung adenocarcinoma cells were cultured in vitro, and the knockout efficiency was verified by Western blot and reverse transcription-quantitative polymerase chain reaction (RT-qPCR), and cell proliferation experiments were performed.@*RESULTS@#The expression of DEPDC1 in lung adenocarcinoma tissues is significantly higher than that in adjacent normal tissues. The high expression of DEPDC1 is correlated with the tumor size and clinical stage of lung adenocarcinoma and knocking down DEPDC1 inhibits the proliferation of A549 and H1975 cells.@*CONCLUSIONS@#DEPDC1 plays an important role in the progression and evolution of lung adenocarcinoma. And it is expected to become an important therapeutic target and a potential new biomarker for lung adenocarcinoma.
RESUMEN
BACKGROUND@#The pathogenesis of osteosarcoma (OS) is still unclear, and it is still necessary to find new targets and drugs for anti-OS. This study aimed to investigate the role and mechanism of the anti-OS effects of miR-296-5p.@*METHODS@#We measured the expression of miR-296-5p in human OS cell lines and tissues. The effect of miR-296-5p and its target gene staphylococcal nuclease and tudor domain containing 1 on proliferation, migration, and invasion of human OS lines was examined. The Student's t test was used for statistical analysis.@*RESULTS@#We found that microRNA (miR)-296-5p was significantly downregulated in OS cell lines and tissues (control vs. OS, 1.802 ± 0.313 vs. 0.618 ± 0.235, t = 6.402, P < 0.01). Overexpression of miR-296-5p suppressed proliferation, migration, and invasion of OA cells. SND1 was identified as a target of miR-296-5p by bioinformatic analysis and dual-luciferase reporter assay. Overexpression of SND1 abrogated the effects induced by miR-296-5p upregulation (miRNA-296-5p vs. miRNA-296-5p + SND1, 0.294 ± 0.159 vs. 2.300 ± 0.277, t = 12.68, P = 0.003).@*CONCLUSION@#Our study indicates that miR-296-5p may function as a tumor suppressor by targeting SND1 in OS.
