RESUMO
Objective: To analyze the clinical characteristics and prognosis of patients with infant acute lymphoblastic leukemia (IALL). Methods: A retrospective cohort study.Clinical data, treatment and prognosis of 28 cases of IALL who have been treated at Beijing Children's Hospital, Capital Medical University and Baoding Children's Hospital from October 2013 to May 2023 were analyzed retrospectively. Based on the results of fluorescence in situ hybridization (FISH), all patients were divided into KMT2A gene rearrangement (KMT2A-R) positive group and KMT2A-R negative group. The prognosis of two groups were compared. Kaplan-Meier method and Log-Rank test were used to analyze the survival of the patients. Results: Among 28 cases of IALL, there were 10 males and 18 females, with the onset age of 10.9 (9.4,11.8) months. In terms of immune classification, 25 cases were B-ALL (89%), while the remaining 3 cases were T-ALL (11%). Most infant B-ALL showed pro-B lymphocyte phenotype (16/25,64%). A total of 22 cases (79%) obtained chromosome karyotype results, of which 7 were normal karyotypes, no complex karyotypes and 15 were abnormal karyotypes were found. Among abnormal karyotypes, there were 4 cases of t (9; 11), 2 cases of t (4; 11), 2 cases of t (11; 19), 1 case of t (1; 11) and 6 cases of other abnormal karyotypes. A total of 19 cases (68%) were positive for KMT2A-R detected by FISH. The KMT2A fusion gene was detected by real-time PCR in 16 cases (57%). A total of 24 patients completed standardized induction chemotherapy and were able to undergo efficacy evaluation, 23 cases (96%) achieved complete remission through induction chemotherapy, 4 cases (17%) died of relapse. The 5-year event free survival rate (EFS) was (46±13)%, and the 5-year overall survival rate (OS) was (73±10)%.The survival time was 31.3 (3.3, 62.5) months. There was no significant statistical difference in 5-year EFS ((46±14)% vs. (61±18)%) and 5-year OS ((64±13)% vs. (86±13)%) between the KMT2A-R positive group (15 cases) and the KMT2A-R negative group (9 cases) (χ2=1.88, 1.47, P=0.170, 0.224). Conclusions: Most IALL patients were accompanied by KMT2A-R. They had poor tolerance to traditional chemotherapy, the relapse rate during treatment was high and the prognosis was poor.

Objective To measure the diameter of the corpus callosum in children aged 0-14 years using midsagittal high-resolution MRI,and to find the normal reference values of the diameter of the corpus callosum in children of different ages.Methods The imaging data of 967 children with normal brain MRI were retrospectively selected and grouped according to age.The anteroposterior diameter(APD),thickness of the genu(GT),thickness of the body(BT),thickness of the isthmus(IT),thickness of the splenium(ST)and fronto-occipital diameter(FOD)of the corpus callosum were measured on the midsagittal plane of the brain.The diameters of the corpus callosum on the midsagittal plane of the brain of children at different ages were measured.The correlation analysis between the diameter of the corpus callosum and age were performed.Results The APD,GT,BT,IT,ST and FOD were positively correlated with age(r=0.660,0.590,0.528,0.521,0.660,0.597,P<0.01).The IT variation was the greatest in the subregions of the corpus callosum.The growth peak of GT and ST of corpus callosum appeared before 2 years of age.Conclusion The establishment of the normal reference value of different subregions of the corpus callosum in children can help to accurately evaluate the development of the corpus callosum,which is conducive to the evaluation of the prognosis of diseases related to the corpus callosum.
RESUMO
The Healthy China construction initiative highlights the concept of patient-centered value-based health care,and the value appeal of doctors'medical service is also increasing.This study attempts to introduce the concept of public service motivation in general public organizations into professional public healthcare organizations——public hospitals,and proposes the concept of"value-based medical service motivation"as an expression of public service motivation for doctors in public hospitals.Through qualitative analysis and quantitative measurement,this paper constructs the concept of"public hospital doctors'value-based medical service motivation",finds its conceptual structure,namely responsibility commitment,professional adherence,reputation maintenance,and norm compliance,and finally forms a value-based medical service motivation scale.This paper confirms that doctors in public hospitals in China have multi-dimensional value-based medical service motivation,present different motivational expressions or behavioral tendencies,and constantly deal with and balance the public value tensions in the practice of realizing the patient-centered value-based medical goal.This scale provides an effective tool for measuring doctors'value-based service motivation,and provides theoretical and practical support for further investigating the influencing factors of doctors'motivation for value-based medical services,improving the medical service capacity of public hospitals,adjusting medical behavior,and advancing doctor-patient trust.
RESUMO
AIM: To observe the effect of soluble glycoprotein 130(sgp130)on expression of p-STAT3 and vascular endothelial growth factor(VEGF)-A in retina of mice with diabetes mellitus(DM), and explore the possibility of sgp130 in interfering with inflammatory damage of diabetic retinopathy(DR).METHODS: A total of 45 mice were randomly divided into normal group, DM group and sgp130 group. DM models were made in DM group and sgp130 group with streptozotocin. No special intervention was given to normal group and DM group, but sgp130 group was given intravitreal injection of 1.5mg/mL sgp130 2μL at the 1 and 5wk. After 10wk, all the mice were sacrificed to assess the protein expression of interleukin 6(IL-6), p-STAT3 and VEGF-A in the retina.RESULTS: The expressions of IL-6, p-STAT3 and VEGF-A in retina of DM group were higher than those of normal group at 10wk(all P<0.01). The expression of p-STAT3 and VEGF-A in sgp130 group were lower than those in DM group(all P<0.01).CONCLUSION: The sgp130 can selectively antagonize the trans signal transduction pathway of IL-6, down-regulate the expression of downstream inflammatory factors VEGF-A, and it may be used in the intervention of retinal inflammatory damage related with IL-6 in DM.
RESUMO
Placental transmogrification of the lung (PTL) is a very rare benign lung lesion. There are only about 40 cases reported in the literature. The imaging and histological features of PTL cases in the publication are various, most of which are cystic and a few of which are solid. Being extremely rare, the solid PTL is unknown to major pathologists and surgeons. We reported a case of solid PTL in the anterior mediastinum. The patient was a 52-year-old male with no history of smoking and without symptoms. During physical examination, chest CT revealed a circular low-density lesion with a maximum diameter of 2.9 cm beside the spine in the posterior basal segment of the left lower lobe of the lung. The wedge resection was performed by video-assisted thoracoscopy. Grossly, a round nodule was located underneath the visceral pleura. It was about 3.0 cm×3.0 cm×1.6 cm and the cut surface was grey-red, soft and spongy. Microscopically, the nodule was constituted of papillare, which resembled placental villi at low magnification. The axis of papillae was edema, in which some mild round cells with clear cytoplasm and CD10 positive staining aggregated and transitioned to immature adipocytes and amorphous pink materials deposited with a few of inflammatory cells infiltration. The surface of papillae was covered with disconti-nuous alveolar epithelium. Combined with the typical morphology and immunohistochemical characteristics of CD10 positive, the diagnosis was PTL. The patient was followed up for 1 year without recurrence and discomfort. So far, the pathogenesis of PTL is unclear. The major hypotheses include hamartoma, variant of emphysema and clonal hyperplasia of stromal cells. Based on the study of our case and publication, we speculate that the hyperplasia of stromal cells located in the alveolar septa might be the first step to form the solid PTL. With the progression of the disease, a typical unilateral cystic nodule develops as a result of secondary cystic degeneration due to the occlusive valve effect. Surgery is the only option for diagnosis and treatment of PTL. The clinician should make an individualized operation plan according to the clinical manifestations, location and scope of the lesion, and preserve the surrounding normal lung tissue as much as possible while completely removing the lesion. There is a favorable prognosis.

Objective: To analyze the phenotype and genotype of two pedigrees with inherited fibrinogen (Fg) deficiency caused by two heterozygous mutations. We also preliminarily probed the molecular pathogenesis. Methods: The prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and plasma fibrinogen activity (Fg∶C) of all family members (nine people across three generations and three people across two generations) were measured by the clotting method. Fibrinogen antigen (Fg:Ag) was measured by immunoturbidimetry. Direct DNA sequencing was performed to analyze all exons, flanking sequences, and mutated sites of FGA, FGB, and FGG for all members. Thrombin-catalyzed fibrinogen polymerization was performed. ClustalX 2.1 software was used to analyze the conservatism of the mutated sites. MutationTaster, PolyPhen-2, PROVEAN, SIFT, and LRT online bioinformatics software were applied to predict pathogenicity. Swiss PDB Viewer 4.0.1 was used to analyze the changes in protein spatial structure and molecular forces before and after mutation. Results: The Fg∶C of two probands decreased (1.28 g/L and 0.98 g/L, respectively). The Fg∶Ag of proband 1 was in the normal range of 2.20 g/L, while it was decreased to 1.01 g/L in proband 2. Through genetic analysis, we identified a heterozygous missense mutation (c.293C>A; p.BβAla98Asp) in exon 2 of proband 1 and a heterozygous nonsense mutation (c.1418C>G; p.BβSer473*) in exon 8 of proband 2. The conservatism analysis revealed that Ala98 and Ser473 presented different conservative states among homologous species. Online bioinformatics software predicted that p.BβAla98Asp and p.BβSer473* were pathogenic. Protein models demonstrated that the p.BβAla98Asp mutation influenced hydrogen bonds between amino acids, and the p.BβSer473* mutation resulted in protein truncation. Conclusion: The dysfibrinogenemia of proband 1 and the hypofibrinogenemia of proband 2 appeared to be related to the p.BβAla98Asp heterozygous missense mutation and the p.BβSer473* heterozygous nonsense mutation, respectively. This is the first ever report of these mutations.

The study aimed to examine the effects of virtual reality (VR) technology-based phase I cardiac rehabilitation (CR) program in elderly coronary heart disease (CHD) patients after percutaneous coronary intervention (PCI). Thirty-six cases of elderly CHD patients who underwent PCI in the First Affiliated Hospital of Chongqing Medical University from June 2022 to April 2023 were recruited by convenience sampling method. The patients were randomly assigned by means of random digital table method to two study groups: control group (n = 18), which received conventional nursing intervention after PCI, and experimental group (n = 18), which received a combined program of conventional nursing intervention together with CR program based on VR technology. The 6 min walk test (6MWT), Simple Physical Performance Battery (SPPB), SF-36 scale, Hospital Anxiety and Depression Scale (HADS) and Impact of Events Scale-Revised (IES-R) were tested before and after rehabilitation. Moreover, the incidence of major adverse cardiovascular events (MACE) was recorded at 3 months after PCI. After VR-based CR, the 6MWT distance and SPPB scores of patients in the experimental group were higher than those in control group (P < 0.05). The HADS scores and IES-R scores of the patients in the experimental group were lower than those in control group (P < 0.01), and the difference in SF-36 scale scores was not statistically significant between two groups (P > 0.05). The incidence of MACE was not significantly different at 3 months after PCI (P > 0.05). These results suggest that VR-based phase I CR program mitigates the degree of PCI postoperative stress, anxiety, and depression in elderly CHD patients, however, enhances the resistance to fatigue and does not increase the risk of adverse cardiac events, suggesting it is a safe intervention.

OBJECTIVE@#Omicron, a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant, is responsible for numerous infections in China. This study investigates the association between the use of Seven-Flavor Herb Tea (SFHT) and the risk of SARS-CoV-2 infection to develop precise and differentiated strategies for control of the coronavirus disease 2019 (COVID-19).@*METHODS@#This case-control study was conducted at shelter hospitals and quarantine hotels in China. A total of 5348 laboratory-confirmed COVID-19 patients were enrolled between April 1 and May 31, 2022, while 2190 uninfected individuals served as healthy controls. Structured questionnaires were used to collect data on demographics, underlying diseases, vaccination status, and use of SFHT. Patients were propensity-score-matched using 1:1 nearest-neighbor matching of the logit of the propensity score. Subsequently, a conditional logistic regression model was used for data analysis.@*RESULTS@#Overall, 7538 eligible subjects were recruited, with an average age of [45.54 ± 16.94] years. The age of COVID-19 patients was significantly higher than that of uninfected individuals ([48.25 ± 17.48] years vs [38.92 ± 13.41] years; t = 22.437, P < 0.001). A total of 2190 COVID-19 cases were matched with uninfected individuals at a 1:1 ratio. The use of SFHT (odds ratio = 0.753, 95% confidence interval: 0.692, 0.820) was associated with a lower risk of SARS-CoV-2 infection compared to untreated individuals.@*CONCLUSION@#Our findings suggest that taking SFHT reduces the risk of SARS-CoV-2 infection. This is a useful study in the larger picture of COVID-19 management, but data from large-sample multi-center, randomized clinical trial are warranted to confirm the finding.

ObjectiveArtificial intelligence (AI) full smear automated diatom detection technology can perform forensic pathology drowning diatom detection more quickly and efficiently than human experts.However, this technique was only used in conjunction with the strong acid digestion method, which has a low extraction rate of diatoms. In this study, we propose to use the more efficient proteinase K tissue digestion method (hereinafter referred to as enzyme digestion method) as a diatom extraction method to investigate the generalization ability and feasibility of this technique in other diatom extraction methods. MethodsLung tissues from 6 drowned cadavers were collected for proteinase K ablation and made into smears, and the smears were digitized using the digital image matrix cutting method and a diatom and background database was established accordingly.The data set was divided into training set, validation set and test set in the ratio of 3:1:1, and the convolutional neural network (CNN) models were trained, internally validated, and externally tested on the basis of ImageNet pre-training. ResultsThe results showed that the accuracy rate of the external test of the best model was 97.65 %, and the area where the model features were extracted was the area where the diatoms were located. The best CNN model in practice had a precision of more than 80 % for diatom detection of drowned corpses. ConclusionIt is shown that the AI automated diatom detection technique based on CNN model and enzymatic digestion method in combination can efficiently identify diatoms and can be used as an auxiliary method for diatom detection in drowning identification.
RESUMO
Chronic atrophic gastritis (CAG) and gastric intestinal metaplasia (GIM) significantly increase the risk of gastric cancer. Blocking the development of CAG and GIM would help to decrease the incidence of gastric cancer. It was revealed that eradication of Helicobacter pylori could reverse gastric mucosa atrophy. Recent studies reported that GIM could be reversed to a certain extent. Clinical studies demonstrated that Lamb′s tripe extract and vitamin B12 capsule exhibited significant reversal effects on GIM. The present study systemically reviewed the diagnosis and treatment of CAG and clinical application of Lamb′s tripe extract and vitamin B12 capsule, and established the specialist instruction that would guide the reversal treatment of CAG and GIM.

OBJECTIVES@#To select four algorithms with relatively balanced complexity and accuracy among deep learning image classification algorithms for automatic diatom recognition, and to explore the most suitable classification algorithm for diatom recognition to provide data reference for automatic diatom testing research in forensic medicine.@*METHODS@#The "diatom" and "background" small sample size data set (20 000 images) of digestive fluid smear of corpse lung tissue in water were built to train, validate and test four convolutional neural network (CNN) models, including VGG16, ResNet50, InceptionV3 and Inception-ResNet-V2. The receiver operating characteristic curve (ROC) of subjects and confusion matrixes were drawn, recall rate, precision rate, specificity, accuracy rate and F1 score were calculated, and the performance of each model was systematically evaluated.@*RESULTS@#The InceptionV3 model achieved much better results than the other three models with a balanced recall rate of 89.80%, a precision rate of 92.58%. The VGG16 and Inception-ResNet-V2 had similar diatom recognition performance. Although the performance of diatom recall and precision detection could not be balanced, the recognition ability was acceptable. ResNet50 had the lowest diatom recognition performance, with a recall rate of 55.35%. In terms of feature extraction, the four models all extracted the features of diatom and background and mainly focused on diatom region as the main identification basis.@*CONCLUSIONS@#Including the Inception-dependent model, which has stronger directivity and targeting in feature extraction of diatom. The InceptionV3 achieved the best performance on diatom identification and feature extraction compared to the other three models. The InceptionV3 is more suitable for daily forensic diatom examination.

OBJECTIVE@#To investigate the effect of palmitic acid (PA) on autophagy in neonatal rat cardiomyocytes (NRCMs) and explore the underlying mechanism.@*METHODS@#NRCMs were isolated and cultured for 24 h before exposure to 10% BSA and 0.1, 0.3, 0.5, or 0.7 mmol/L PA for 24 h. After the treatments, the expressions of Parkin, PINK1, p62, LC3Ⅱ/ LC3Ⅰ, cGAS, STING and p-IRF3/IRF3 were detected using Western blotting and the cell viability was assessed with CCK8 assay, based on which 0.7 mmol/L was selected as the optimal concentration in subsequent experiments. The effects of cGAS knockdown mediated by cGAS siRNA in the presence of PA on autophagy-related proteins in the NRCMs were determined using Western blotting, and the expressions of P62 and LC3 in the treated cells were examined using immunofluorescence assay.@*RESULTS@#PA at different concentrations significantly lowered the expressions of Parkin, PINK1, LC3 Ⅱ/LC3 Ⅰ and LC3 Ⅱ/LC3 Ⅰ+Ⅱ (P < 0.05), increased the expression of p62 (P < 0.05), and inhibited the viability of NRCMs (P < 0.05). Knockdown of cGAS obviously blocked the autophagy-suppressing effect of PA and improved the viability of NRCMs (P < 0.05).@*CONCLUSION@#PA inhibits autophagy by activating the cGAS-STING-IRF3 pathway to reduce the viability of NRCMs.

The paper summarizes professor LIN Guo-hua's clinical experience in staging treatment for post-stroke dysphagia. Professor LIN Guo-hua adheres to "essence and marrow deficiency and primary yang decline" as the pathogenesis and "conducting yin from yang " as the treating principle. By regulating the conception vessel and the governor vessel and focusing on yang meridians, in association with meridian differentiation and the location differentiation, professor LIN provides the staging treatment for post-stroke dysphagia. At the oral phase, yangming is dysfunction, manifested as facial paralysis and flaccid tongue. In treatment, reducing method is predominated at yangming meridian specially. At the pharyngeal phase, shaoyang is invaded by pathogens, manifested as pivoting dysfunction. The treatment focuses on communicating the exterior with the interior and promoting shaoyang meridian. At the esophageal phase, yangming meridian is deficiency and the turbid qi fails to descend, thus the reinforcing method is dominated to promote and tonify yangming. Additionally, the kinesiotherapy of acupuncture is assisted and the Lingnan fire needling therapy is used particularly. All of the summaries above provide the reference for the clinical treatment of post-stroke dysphagia.

RESUMO
Aim To explore the anti-inflammatory effect of natural compound Ginkgetin on lipopolysaccharide-induced mouse primary peritoneal macrophages and the underlying mechanism, in order to provide a theoretical basis for the development of clinical drug candidates. Methods MTT test kit was used to detect the cytotoxicity of Ginkgetin on mouse primary peritoneal macrophages; ELISA and RT-qPCR methods were used to detect the anti-inflammatory effect of different concentrations of Ginkgetin on LPS-induced cell inflammation injury model; Western blot was used to detect the anti-inflammatory mechanism of ginkgo flavonoids. Results Compared with LPS stimulation group, Ginkgetin treatment group produced a concentration-dependent anti-inflammatory effect, which could be attributed to the fact that Ginkgetin could inhibit LPS-induced activation of NF-κB signaling pathway. MTT results also showed that ginkgo flavonoids had little toxicity to mouse primary peritoneal macrophages. Conclusions Ginkgelin alleviates LPS-induced inflammatory injury of mouse primary peritoneal macrophages by inhibiting the activation of NF-κB signaling pathway. It is expected to be a natural monomer antiinflammatory drug candidate.
