RESUMEN
Pseudogenes were initially thought to have no function and were called by aliases, such as "junk genes." With the emergence of large-scale genomics projects and more and more experimental studies, pseudogenes have been shown to play an important role in the occurrence and development of solid tumors, especially playing an important regulatory role in the occurrence and develepment of liver cancer, such as regulating the proliferation, apoptosis, invasion, metastasis, and immunity of liver cancer cells. Recent studies showed that pseudogenes can act as regulators of oncogenes and tumor suppressors in hepatocellular carcinoma (HCC) and can thus serve as prognostic markers and even therapeutic targets for this cancer type. In this review, we systematically summarize the mechanisms and functions of different pseudogenes in HCC and present their future prospects as therapeutic targets.
RESUMEN
Estimation of postmortem interval (PMI) is one of the important research contents in forensic pathology, and it has always been the focus and hot spot of research work. In recent years, scholars at home and abroad have made some research progress in estimating PMI by using ocular tissue. After death, the changes of cornea, aqueous humor, iris, lens, vitreous humor and retina all show time sequence change rule highly related to PMI. This paper reviews the research progress of PMI estimation based on the morphological, biochemical, molecular and genetic material changes of different ocular tissue structures after death, and discusses the existing problems and development trends.

OBJECTIVES@#To investigate the concentration and change characteristics of 1, 5-anhydroglucitol (1, 5-AG) in the vitreous humor of rabbit cadavers with hyperglycemic metabolism, and to explore the value of 1, 5-AG in forensic pathology identification of death caused by hyperglycemic metabolism disorders.@*METHODS@#A diabetic hyperglycemic rabbit model was established by using alloxan. Eighteen rabbits with fasting glucose concentration ≥13.80 mmol/L (experimental group) and 18 healthy rabbits with fasting glucose concentration ≤6.10 mmol/L (control group) were selected. After death from air embolism. The blood samples were collected immediately, and vitreous humor samples were collected at 0 h, 12 h, 24 h and 36 h after death. The concentration of 1, 5-AG in the blood and vitreous humor of rabbits was determined.@*RESULTS@#The blood glucose concentration in the experimental group was (25.10±3.14) mmol/L. At the time of death, there was no significant difference in the concentration of 1, 5-AG in the blood [(0.94±0.20) μg/mL] and in the vitreous humor (0.99±0.05 μg/mL, P>0.05). The concentration of 1, 5-AG in the vitreous humor of the experimental group was lower than that of the corresponding control group at all time points (P<0.05), and there was no significant difference betwwen 1, 5-AG concentration in vitreous humor between earch time point in the experimental group and the control group (P>0.05). Correlation analysis showed that the concentration of 1,5-AG in blood was negatively correlated with blood glucose in both control group and experimental group (control group: r=-0.79, P<0.05; experimental group: r=-0.97, P<0.05).@*CONCLUSIONS@#Vitreous humor can replace blood as an effective test sample for 1,5-AG detection. The concentration of 1, 5-AG in rabbit vitreous humor remains stable within 36 hours after death and is not affected by the change of postmortem interval. If the concentration of 1, 5-AG decreases significantly, it indicates the existence of hyperglycemia in rabbits before death.

Radiotherapy is a primary method for treating tumors. However, since surrounding healthy tissues may also receive a certain dose of irradiation during the radiotherapy, they may suffer from radiation-induced damage, which is even serious for certain patients. Injectable hydrogels are expected to achieve the spacing between target areas and their surrounding tissues during radiotherapy, thus increasing the dose to the target areas while reducing the risk of radiation-induced damage to surrounding healthy tissues and organs. Accordingly, the quality of life of the patients can be improved. Therefore, applying injectable hydrogels serves as a potential strategy for reducing the adverse reactions associated with radiotherapy. This paper reviews the latest research progress in the spacing and protection of hydrogels in radiotherapy for different tumors.
RESUMEN
Objective:To compare the clinical effect of "de-sharpening" intramedullary elastic reduction with Kirschner wire and traditional three-dimensional manipulation for the treatment of Gartland type III posterolaterally-displaced supracondylar humerus fracture in children.Methods:A retrospective cohort analysis was made on 106 children with Gartland type III posterolaterally-displaced supracondylar humerus fracture treated in Anhui Provincial Children′s Hospital from March 2020 to June 2022, including 58 males and 48 females; aged 1-12 years [(8.7±2.3)years]. The patients were assigned to "de-sharpening" intramedullary elastic reduction with Kirschner wire (study group, n=50) and traditional three-dimensional manipulation (control group, n=56). The operation time, frequency of intraoperative fluoroscopy, fracture healing time, difference of Baumann angle between the normal and injured side at postoperative 3 and 6 months, elbow function Flynn score at last follow-up and complications were compared between the two groups. Results:All children were followed up for 6-12 months [(8.5±1.2)months]. The operation time and frequency of intraoperative fluoroscopy were (32.9±3.7)minutes and (20.6±5.4)times in study group, significantly different from (45.6±10.1)minutes and (32.5±8.2)times in control group (all P<0.05). The fracture healing time was (33.0±5.1)days in study group, similar with (33.8±4.7)days in control group ( P>0.05). At 3 and 6 months after operation, the difference of Baumann angle between the normal and injured side was (3.2±0.8)°and (2.3±0.6)°in study group compared to (6.0±2.1)°and (5.8±1.3)°in control group (all P<0.01). According to the elbow function Flynn score at the last follow-up, the results were excellent in 44 children, good in 5 and fair in 1, with the excellent and good rate of 98.0% (49/50) in study group, and were excellent in 47 children, good in 5 and fair in 4, with the excellent and good rate of 92.9% (52/56) in control group ( P>0.05). There were no following complications in both groups, such as osteomyelitis, poor fracture healing, compartment syndrome, iatrogenic neurovascular injury or myositis ossificans. Conclusions:Both "de-sharpening" intramedullary elastic reduction with Kirschner wire and traditional three-dimensional manipulation for the treatment of Gartland type III posterolaterally-displaced supracondylar humerus fracture in children can achieve elbow joint function recovery, with low incidence of complications. However, the former avoids repeated manual reduction, with shorter operation time, less frequency of intraoperative fluoroscopy and better correction of the coronal plane deformity and rotation deformity.

Objective:To analyze the plague monitoring results of Marmota sibirica plague natural focus in Hulunbuir Plateau, and to study the characteristics of development and variation of the plague focus. Methods:From 2009 to 2020, monitoring was conducted in Manzhouli City, Prairie Chenbarhu Banner, Xin Barag Left Banner, and Xin Barag Right Banner from May to September each year. The one-day bow-clip method was used to investigate the density of the Spermophilus dauricus, and the 5-meter clamp method was used to investigate other small rodents. The classification and identification of ectoparasite fleas were done by using low power microscope. According to "Diagnostic Criteria for Plague" (WS 279-2008), the detectable materials of rats and fleas were tested, and Yersinia pestis was isolated and cultured. The serums of collected rats were detected by indirect hemagglutination test. Results:From 2009 to 2020, the average density of dauricus in Marmota sibirica plague natural focus of Hulunbuir Plateau was 0.45/hm 2, and the capture rate of other small rodents was 1.25% (787/63 091). A total of 9 species, 8 genera and 4 families of rodents were captured. The total flea infection rate of Spermophilus dauricus was 28.37% (1 945/6 856) and the fleas index was 1.04. A total of 3 species, 3 genera and 2 families of fleas were collected. A total of 6 674 Spermophilus dauricus were dissected and 6 787 fleas were cultured in 2 537 groups. The Yersinia pestis test was negative. A total of 6 795 serum samples from Spermophilus dauricus were detected, of which 11 were positive with a positive detection rate of 0.16%. The highest titer of positive serum was 1∶1 280. Indirect hemagglutination test positive materials were found for 5 consecutive years from 2010 to 2014; the positive serums were found in Manzhouli City and Xin Barag Right Banner. Conclusions:The Yersinia pestis antibady positive serum of Spermophilus dauricus has been detected in Marmota sibirica plague focus of Hulunbuir Plateau for many years, which is worthy of high vigilance. In the future, continuous surveillance should be carried out, bacterial detection should be strengthened, possible plague outbreaks should be detected in time, and various plague prevention and control should be done well.
RESUMEN
Due to the physiological peculiarities of pregnant women, general clinical studies exclude pregnant women. Therefore, there is a lack of evidence of precise medication for pregnant women with diseases worldwide, which poses a significant risk for them to use medication during pregnancy. Whether to include pregnant women as subjects in clinical research has always been a focus of ethical discussion. By providing a broad overview of pregnant women’s participation in clinical research from an ethical perspective, this paper explored the risks and challenges faced by pregnant women’s participation in clinical research, and provided theoretical basis and thinking paths for how to fairly and effectively include pregnant women as subjects and promoting clinical research on pregnant women.
RESUMEN
Objective@#Limited evidence exists regarding real-world 3-monthly paliperidone palmitate (PP3M) treatment retention and associated factors. @*Methods@#We conducted a retrospective, nationwide cohort study using the Taiwan National Health Insurance Research Database between October 2017 and December 2019. Adult patients with schizophrenia initiated on PP3M were enrolled. The primary outcomes were time to PP3M discontinuation, time to psychiatric hospitalization, and the proportions of patients receiving the next PP3M dose within 120 days among first-, second-, and third-dose completers. Key covariates included prior PP1M duration and adequate PP3M initiation. @*Results@#The PP3M treatment retention rates were 79.7%, 66.3%, and 52.5% after 6, 12, and 24 months, respectively, with 86.4%, 90.6%, and 90.0% of respective first-, second-, and third-dose completers receiving the next PP3M dose. Adequate PP3M initiation and prior PP1M treatment duration ＞ 180 days were associated with favorable PP3M treatment retention. In multivariate analyses, PP1M durations of 180−360 days (adjusted relative risk [aRR], 1.76) or ＜ 180 days (aRR, 2.79) were associated with PP3M discontinuation at the second dose. Inadequate PP3M initiation was associated with discontinuation at the third dose (aRR, 2.18). Patients fully adherent to PP3M treatment in the first year had a higher probability of being free from psychiatric hospitalization (86.7% at 2 years), compared with those partially adherent or non-adherent to PP3M in the first year. @*Conclusion@#Prior PP1M duration and adequate PP3M initiation are major factors affecting PP3M treatment retention. Higher PP3M treatment retention is associated with a lower risk of psychiatric hospitalization.
RESUMEN
The Ca2+-activated monovalent cation selective transient receptor potential melastatin 4 (TRPM4) channel expressed in pancreatic β-cells is implicated in the β-cell function and insulin secretion, but how pharmacological function of TRPM4 channel affects membrane excitability of β-cells remains largely unknown. Here, we report that pharmacological inhibition of TRPM4 by specific inhibitor 9-phenanthrol attenuates electrical activities of pancreatic β-cells. In whole-cell current clamp recordings, 9-phenanthrol results in inhibition of action potential frequency induced by tolbutamide of the INS-1 pancreatic β-cells in a dose-dependent manner with an IC50 value of 14.99 ± 7.93 μmol·L-1. Similarly, 9-phenanthrol also inhibited action potential firing in INS-1 cells stimulated by current injection. Further recordings of β-cells demonstrate the significant inhibitory effects on action potential peak and action potential amplitude by 9-phenanthrol. Taken together, our results show the involvement of TRPM4 channel function in pancreatic β-cells depolarization and action potential, it provides pharmacological experimental methods and theoretical support for the study of TRPM4 channel in pancreatic β-cells.
RESUMEN
ObjectiveTo investigate the value of MELD 3.0， MELD， and MELD-Na scores in assessing the 90-day prognosis of patients with acute-on-chronic liver failure （ACLF） through a comparative study. MethodsA retrospective analysis was performed for the clinical data of 605 patients with ACLF who were treated in Tianjin Third Central Hospital， The Fifth Medical Center of Chinese PLA General Hospital， and Beijing YouAn Hospital from November 2012 to June 2019， and according to the 90-day follow-up results after admission， they were divided into survival group with 392 patients and death group with 213 patients. The receiver operating characteristic （ROC） curve， the area under the ROC curve （AUC）， net reclassification improvement （NRI）， integrated discrimination improvement （IDI）， and decision curve analysis （DCA） curve were used to investigate the value of MELD 3.0， MELD， and MELD-Na scores at baseline， day 3， week 1， and week 2 in predicting the prognosis of the disease. ResultsAt day 3 and week 1， MELD 3.0 score had an AUC of 0.775 and 0.808， respectively， with a better AUC than MELD score （P<0.05）. At day 3， week 1， and week 2， MELD 3.0 score showed an NRI of 0.125， 0.100， and 0.081， respectively， compared with MELD in predicting the prognosis of ACLF patients， as well as an NRI of 0.093， 0.140， and 0.204， respectively， compared with MELD-Na score in predicting prognosis. At baseline， day 3， week 1， and week 2， MELD 3.0 showed an IDI of 0.011， 0.025， 0.017， and 0.013， respectively， compared with MELD in predicting the prognosis of ACLF patients. At day 3 and week 2， MELD 3.0 showed an IDI of 0.027 and 0.038， respectively， compared with MELD-Na in predicting the prognosis of ACLF patients. All the above NRIs and IDIs were >0， indicating a positive improvement （all P<0.05）. DCA curves showed that MELD 3.0 was superior to MELD at day 3 and was significantly superior to MELD-Na at week 2. There was no significant difference in the ability of the three scores in predicting the prognosis of ACLF patients with different types， and there was also no significant difference in the ability of the three scores in predicting the prognosis of ACLF patients with the etiology of HBV infection， alcohol， or HBV infection combined with alcohol， while MELD 3.0 was superior to MELD for ACLF patients with other etiologies （P<0.05）. ConclusionMELD 3.0 score is better than MELD and MELD-Na scores in predicting the 90-day survival of patients with ACLF， but with limited superiority.
RESUMEN
ObjectiveTo explore psychological and behavioral characteristics of children with autism spectrum disorder (ASD) using Psycho-educational Profile (Third Edition) (PEP3). MethodsFrom October, 2021 to October, 2022, 192 children with ASD without intervention in the Binzhou Medical University Hospital were selected as observation group, and 96 healthy children who visited at the same time were selected as control group. They were assessed with PEP3. ResultsThe development of receptive language significantly delayed behind expressive language (t = 5.383, P < 0.001) in the observation group. The cognitive, expressive language, receptive language, fine motor, gross motor, imitation and personal self-care correlated with age (r = 0.540 to 0.795, P < 0.001). The Cronbach's α of PEP3 for the observation group was 0.810 to 0.947. The original score of each subtest of PEP3 was less in the observation group than in the control group (|t| > 4.267, P < 0.001). ConclusionThe development of receptive language retards behind the expressive language in children with ASD. Cognitive and motor functions develop with age, while the correlation between maladaptive behavior and age is weak. PEP3 is reliable in internal consistency, and valid in discrimination.
RESUMEN
ObjectiveTo explore the effect of interaction of hypertension and abdominal obesity on morbidity of diabetes and to provide the scientific bases for preventing diabetes. MethodsA total of 11 914 people who took the physical examination in 2019 were examined with cluster sampling method for the interaction analysis. The data was collected by physical measurements and laboratory tests. SPSS 16.0 and interaction models were used for data analysis. ResultsIn the subjects there were 75.19% with abdominal obesity， 47.99% with hypertension， 16.26% with diabetes， and 39.42% had abdominal obesity plus hypertension. Multivariate logistic regression analysis showed， after adjusting gender and age， the abdominal obesity（OR=1.29， 95%CI：1.14‒1.46） and hypertension （OR=2.93， 95%CI： 2.63‒3.26） were related to high risk of diabetes. There was no multiplicative interaction effect between abdominal obesity and hypertension （OR=0.98，95%CI： 0.76‒1.27）. The additive interaction was significant between abdominal obesity and hypertension with RERI=0.53（95%CI：0.09‒0.98）， AP=0.14（95%CI：0.02‒0.26）， and SI=1.24（95%CI：1.01‒1.52）. ConclusionThere is a synergistic effect on morbidity of diabetes between abdominal obesity and hypertension. The improvement of weight and control of blood pressure could prevent significantly the diabetes.
RESUMEN
Objective To explore the association between dietary quality and perceived stress among adult Chinese. Methods The China Health and Nutrition Survey (CHNS) was used to investigate the association between dietary quality and perceived stress in Chinese adults. The Chinese Perceived Stress Scale (CPSS) was used to assess the perceived stress in Chinese adults. Binary logistic regression models were utilized to explore the relationship between diet quality and perceived stress. Restricted cubic splines (RCS) were utilized to clarify the dose response relationship between diet quality and perceived stress. Results Binary logistic regression models revealed that adults with CHEI score ranged from P25 to P50 and higher than P75 had 15.1% (OR=0.849，95%CI：0.738-0.977) and 23.0% (OR=0.770，95%CI：0.666-0.891) reduced risk of high perceived stress after multivariable adjustment when compared with adults with CHEI score less than P25. RCS results showed that the OR value of high perceived stress risk decreased gradually with increasing CHEI score in the overall population, but this association was not statistically significant in adults with lower CHEI score. Conclusion High dietary quality is associated with a reduced risk of high perceived stress. This study provides a theoretical reference for the health effects of high dietary quality on high perceived stress risk reduction.

Conclusion:Gender, polyp size, number of polyps, disease perception, and concomitant gastrointestinal symptoms are associated with anxiety and depression in patients with colorectal polyps.
RESUMEN
Objective:To observe any effects of contralateral repeated transcranial magnetic stimulation (rTMS) of the swallowing motor cortex on the swallowing and brainstem auditory evoked potentials (BAEPs) of stroke survivors with dysphagia.Methods:A total of 83 stroke survivors with dysphagia were randomly divided into an ipsilesional stimulation group ( n=22), a contralesional stimulation group ( n=21), a bilateral stimulation group ( n=20), and a control group ( n=20). In addition to their conventional dysphagia training, those in the three stimulation groups received 3Hz rTMS while the control group was given fake stimulation. The treatment was administered daily for 20 minutes, 6 days a week, for 5 consecutive weeks. Before and after the treatment, swallowing function was assessed videofluoroscopically and using the Dysphagia Outcome and Severity Scale (DOSS). The oral and pharyngeal stages of swallowing were evaluated using the videofluoroscopic dysphagia scale (VDS). Brain stem conduction was assessed using BAEPs. Results:After treatment the average DOSS scores of all 4 groups were significantly better than before the treatment. The average DOSS scores of the contralesional and bilateral sti-mulation groups were then significantly better than those of the other two groups. The sub-item and total VDS scores of all 4 groups had decreased significantly, but the average score of the bilateral stimulation group was significantly lower than the control group′s average. Ipsilesional stimulation significantly improved the VDS sub-item scores for the triggering of pharyngeal swallowing, laryngeal elevation, and pharyngeal transit time compared with the control group. In the contralesional stimulation group the average total score and the VDS sub-item scores for apraxia, premature bolus loss, oral transit times, the triggering of pharyngeal swallowing, vallecular residue, laryngeal elevation, coating on the pharyngeal wall, and pharyngeal transit time were significantly lower than those of the control group, on average. After the treatment the latencies of BAEP waves I, III and V and the I-III, III-V and I-V interpeak intervals had decreased significantly in all four groups, but the average latencies and intervals of the bilateral and contralesional groups were significantly shorter than those of the control group. The latencies and intervals of the bilateral stimulation group were then significantly shorter than those in the ipsilesional stimulation group on average. The average latency of wave V in the bilateral stimulation group (6.53±0.73ms) was significantly shorter than that in the contralesional stimulation group after the treatment.Conclusion:Bilateral rTMS over the swallowing motor cortex combined with conventional dysphagia training can significantly improve the swallowing of dysphagic stroke survivors.
RESUMEN
Objective:To investigate the long-term follow-up results and the risk factors of bleeding among very elderly patients with non-valvular atrial fibrillation (NVAF).Methods:A total of 177 patients with NVAF admitted in Beijing Hospital from January 2016 to July 2016 were enrolled in the study, including 107 very elderly patients (aged≥80 years) and 70 elderly patients (aged 65-80 years). The demographic information, comorbid diseases, lifestyles, antithrombotic therapy, thromboembolism risks, bleeding risks, and medical history were documented. Patients were followed up for 5 years and the events of death, thromboembolism, bleeding and major bleeding were recorded.Results:There was no significant difference in the incidence of thromboembolic events between the two groups (15.9%(17/107) vs. 14.3%(10/70), P>0.05). The proportions of bleeding events and severe bleeding events in the very elderly group were higher than those in the elderly group (45.8%(49/107) vs.10.0%(7/70), 14.0%(15/107) vs. 1.4%(1/70), both P<0.05). According to the bleeding events during follow-up, very elderly patients were divided into bleeding group ( n=49) and non-bleeding group ( n=58). Compared with the non-bleeding group, patients in the bleeding group had an older age, a higher proportion of chronic cardiac insufficiency, chronic kidney disease, malignant tumor, bleeding history and higher bleeding risk score (HAS-BLED score) (all P<0.05). Multivariate logistic regression model analysis showed that age, HAS-BLED score, history of bleeding, and complicated malignant tumor were independent risk factors for bleeding events in very elderly patients with NVAF (all P<0.05). Conclusions:Very elderly patients with NVAF have a similar risk of thromboembolism compared with the younger elderly, but have significantly higher risk of the bleeding and major bleeding. Age, HAS-BLED score, bleeding history, and malignant tumor are independent risk factors for bleeding events in very elderly NVAF patients.
RESUMEN
Clinical data from 11 previously diagnosed and treated patients with hyperthyroidism(Graves′ disease) complicated by liver failure were collected. Among them, 4 cases were drug-induced liver injury leading to liver failure, 1 case had a history of schistosomal liver cirrhosis combined with hyperthyroidism, and 6 cases had hyperthyroidism-induced liver injury(HILI) leading to liver failure. During hospitalization, all patients received supportive therapy and symptomatic treatment with β-blockers. Nine patients were treated with glucocorticoids and artificial liver support therapy. Among the 11 patients, 2 died, 8 patients achieved normal thyroid and liver function within 1-12 months after treatment, and 1 patient with liver cirrhosis had stable liver function in the later stage. After improvement in liver function, 7 patients received isotope therapy, 1 patient underwent total thyroidectomy, and 1 patient received medication. These results indicate that the clinical characteristics differ for drug-induced liver injury and HILI-related liver failure. Early initiation of artificial liver support therapy, in addition to β-blockers and glucocorticoids, is important in alleviating thyroid toxicity and liver damage, thus creating an opportunity for subsequent radioactive iodine or surgical treatment.
RESUMEN
Objective:To investigate the relationship between cardiometabolic index (CMI) and hyperuricemia (HUA) in the health examination population.Methods:It was a cross-sectional study. A total of 21 720 individuals who received health examinations in Xiangya hospital, Central South University between 2020 and 2021 were recruited in this study. Multivariate logistic regression analysis was used to determine the independent correlation between CMI and HUA, and stratified analysis was applied to check whether there were population differences. Then the predictive value of CMI for hyperuricemia in the health examination population was evaluated with the area under the receiver operator characteristic (ROC) curve.Results:Among the 21 720 subjects, 4 418 (20.34%) were detected with HUA. In the HUA group, the body mass index (BMI), waist-to-hip ratio, CMI, total cholesterol, triglyceride, systolic blood pressure, diastolic blood pressure, fasting blood glucose, 2-hour postprandial blood glucose, and blood creatinine levels were all significantly higher than those in the normal uric acid group, while high-density lipoprotein and epidermal growth factor receptor (eGFR) were significantly lower (all P<0.05). Multiple logistic regression analysis showed that after adjusting for relevant factors, CMI was significantly positively correlated with HUA ( OR=1.16, 95% CI: 1.129-1.192); and with the increase of CMI, the risk of HUA increased gradually. Stratified analysis and interaction test according to gender, age, BMI, hypertension, abnormal blood glucose and glomerular filtration rate indicated that CMI was positively associated with the occurrence of HUA in all populations. Compared with that in people with abnormal blood glucose, the correlation between CMI and HUA was more obvious in people with normal blood glucose. The area under the ROC curve (AUC) for CMI to predict HUA was 0.723(95% CI: 0.715-0.731), with a specificity of 0.636 and a sensitivity of 0.698, and the cut-point was 0.693. Conclusion:There was a significant positive correlation between CMI and HUA in the health examination population, which has good predictive value for HUA.
RESUMEN
Objective:To investigate the diagnostic and prognostic value of 68Ga-fibroblast activation protein inhibitor (FAPI) PET for hepatobiliary malignancies. Methods:From July 2020 to February 2023, 33 patients (23 males, 10 females; age (55.4±13.5) years) with suspected or confirmed liver or biliary tract malignancies who underwent 68Ga-FAPI PET in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were retrospectively analyzed. PET images were evaluated by 3 experienced nuclear medicine physicians, and the results of biopsy or postoperative pathology, clinical and imaging follow-up were used as the gold standard. One-way analysis of variance and least significant difference t test were used to compare the differences among groups. Survival analysis was performed using Kaplan-Meier curves and the log-rank test. Results:Of 33 patients, 14 performed PET for initial diagnosis and staging, and 19 for restaging. There were 14 patients with hepatocellular carcinoma (HCC), 13 patients with cholangiocarcinoma (CCA), and 6 patients with gallbladder carcinoma (GBC). The primary tumor of HCC, CCA and GBC all showed significant 68Ga-FAPI uptake, with no statistically significant difference in SUV max among groups ( F=1.58, P=0.250). The sensitivities of 68Ga-FAPI PET for initial diagnosis and restaging of hepatobiliary malignancies were 14/14 and 15/15, respectively. Compared with conventional imaging, 68Ga-FAPI PET changed the diagnosis and staging in 29.2%(7/24) patients. The treatment strategy was changed in 30.3%(10/33) patients with malignant tumors due to 68Ga-FAPI PET findings. Follow-up showed 22 cases survived and 11 cases died, with the overall survival of 355.56(80.00, 516.97) d, and 1- and 2-year survival rates were 68.2% and 57.9%, respectively. Semi-quantitative 68Ga-FAPI PET parameters such as SUV max, target-liver ratio (TLR), and target-blood ratio (TBR) had no significant prognostic value, but the prognosis of the group without distant metastases diagnosed by 68Ga-FAPI PET was significantly better than that of the group with distant metastasis ( P=0.032). Conclusion:68Ga-FAPI PET has high sensitivity for the diagnosis of hepatobiliary malignancies, which can help guide treatment decisions and prognosis evaluation.
RESUMEN
OBJECTIVE@#To study the prognostic value of LPCAT1 in acute myeloid leukemia (AML).@*METHODS@#TaqMan-based reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to detect relative expression of LPCAT1 in 214 newly diagnosed adult AML patients and 24 normal controls. Survival functions were estimated using the Kaplan-Meier method and were compared by the Log-rank test. A Cox proportional hazard regression model was used to identify prognostic factors.@*RESULTS@#The expression level of LPCAT1 in adult AML was 34.37%(1.83%-392.63%), which was significantly lower than 92.81%(2.60%-325.84%) of normal controls (P<0.001). The prognostic significance of LPCAT1 was evaluated in 171 non-acute promyelocytic leukemia patients with complete clinical information and prognostic data. Survival analysis showed that the expression level of LPCAT1 had no significant effect on the prognosis of the whole cohort. However, in AML patients with FAB subtype M2 (AML-M2), the 2-year relapse-free survival (RFS) rate of patients with low LPCAT1 expression was 35.4%(95%CI: 0.107-0.601), which was significantly lower than 79.2%(95%CI: 0.627-0.957) of patients with high LPCAT1 expression (P=0.012). Multivariate analysis showed that low expression of LPCAT1 was an independent risk factor for RFS of AML-M2 patients (HR=0.355, 95%CI: 0.126-0.966, P=0.049).@*CONCLUSION@#In adult AML patients LPCAT1 shows low expression. Low LPCAT1 expression is an independent risk factor for RFS in M2-AML patients.
