RESUMO
Objective@#We aimed to investigate whether 2-[ 18F]fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (2-[ 18F]FDG PET/CT) can aid in evaluating the risk of malignancy in ampullary tumors detected by endoscopy. @*Materials and Methods@#This single-center retrospective cohort study analyzed 155 patients (79 male, 76 female; mean age, 65.7 ± 12.7 years) receiving 2-[ 18F]FDG PET/CT for endoscopy-detected ampullary tumors 5–87 days (median, 7 days) after the diagnostic endoscopy between June 2007 and December 2020. The final diagnosis was made based on histopathological findings. The PET imaging parameters were compared with clinical data and endoscopic features. A model to predict the risk of malignancy, based on PET, endoscopy, and clinical findings, was generated and validated using multivariable logistic regression analysis and an additional bootstrapping method. The final model was compared with standard endoscopy for the diagnosis of ampullary cancer using the DeLong test. @*Results@#The mean tumor size was 17.1 ± 7.7 mm. Sixty-four (41.3%) tumors were benign, and 91 (58.7%) were malignant. Univariable analysis found that ampullary neoplasms with a blood-pool corrected peak standardized uptake value in earlyphase scan (SUVe) ≥ 1.7 were more likely to be malignant (odds ratio [OR], 16.06; 95% confidence interval [CI], 7.13–36.18;P < 0.001). Multivariable analysis identified the presence of jaundice (adjusted OR [aOR], 4.89; 95% CI, 1.80–13.33; P = 0.002), malignant traits in endoscopy (aOR, 6.80; 95% CI, 2.41–19.20; P < 0.001), SUVe ≥ 1.7 in PET (aOR, 5.43; 95% CI, 2.00–14.72; P < 0.001), and PET-detected nodal disease (aOR, 5.03; 95% CI, 1.16–21.86; P = 0.041) as independent predictors of malignancy. The model combining these four factors predicted ampullary cancers better than endoscopic diagnosis alone (area under the curve [AUC] and 95% CI: 0.925 [0.874–0.956] vs. 0.815 [0.732–0.873], P < 0.001). The model demonstrated an AUC of 0.921 (95% CI, 0.816–0.967) in candidates for endoscopic papillectomy. @*Conclusion@#Adding 2-[ 18F]FDG PET/CT to endoscopy can improve the diagnosis of ampullary cancer and may help refine therapeutic decision-making, particularly when contemplating endoscopic papillectomy.

RESUMO
Objective:To investigate the effect of miRNA-3653-3p (miR-3653-3p) on the proliferation and invasion ability of endometrial cancer cells and its related mechanisms.Methods:The data of 356 endometrial cancer patients were downloaded from the OncoLnc database (http://www.oncolnc.org, updated version 2020), and the Kaplan-Meier method was used to analyze the relationship between the expression level of miR-3653-3p and the overall survival of endometrial cancer patients. The miRGator database (https://bio.tools/mirgator_v2.0, updated version 2019) was used to predict the target gene binding to miR-3653-3p. Human endometrial cancer cell lines AN3CA, HEC-1A, HEC-1B, Ishikawa and human normal endometrial epithelial cell line ESC were selected, and the relative expression level of miR-3653-3p was detected by using quantitative real-time fluorescent polymerase chain reaction (qRT-PCR). The cell line with the lowest expression of miR-3653-3p was selected as the research object, which was divided into the negative control group and miR-3653-3p group, and transfected with the control empty vector plasmid and miR-3653-3p overexpression plasmid. CCK-8 method was used to detect the proliferation ability of cells, Transwell method was used to detect the invasion ability of cells, and qRT-PCR and Western blot were used to detect the expression of miR-3653-3p target gene. The effect of miR-3653-3p on the related protein expression of Wnt- β-catenin signaling pathway was detected by using Western blot.Results:Data analysis in the OncoLnc database showed that compared with endometrial cancer patients with low miR-3653-3p expression, patients with high miR-3653-3p expression had better overall survival ( P < 0.01). Compared with human normal endometrial epithelial ESC, the expression levels of miR-3653-3p in endometrial cancer cell lines AN3CA, HEC-1A, HEC-1B, and Ishikawa were all decreased (all P < 0.05), and the relative expression level of miR-3653-3p was the lowest in HEC-1A cells, and HEC-1A cells were selected for subsequent experiments. The result of CCK-8 showed that compared with the negative control group, the ability of HEC-1A cells in the miR-3653-3p group decreased on the 2nd, 3rd, 4th, and 5th days (all P < 0.05). The result of the Transwell chamber invasion test showed that the number of HEC-1A cell invasion after culturing for 26 h in the negative control group and the miR-3653-3p group was (80±11) and (21±4), respectively, and the difference was statistically significant ( t = 5.18, P < 0.01); compared with the negative control group, the number of cell invasion in the miR-3653-3p group decreased. The miRGator database was used to predict that the target gene of miR-3653-3p might be placenta-specific protein 8 (PLAC8). The relative expression levels of PLAC8 mRNA in HEC-1A cells in the negative control group and miR-3653-3p group were (6.26±0.83) and (0.97±0.31), respectively, and the difference was statistically significant ( t = 6.00, P < 0.01); the relative expression level of PLAC8 mRNA in the miR-3653-3p group was lower than that in the negative control group. Compared with the negative control group, the PLAC8 protein of HEC-1A cells decreased, and the expression of Wnt-β-catenin signaling pathway related proteins β-catenin, transforming growth factor β (TGF-β), GSK-3β, and Rac1 decreased in the miR-3653-3p group. Conclusions:miR-3653-3p may inhibit the proliferation and invasion of endometrial cancer cells by regulating the PLAC8-Wnt-β-catenin signaling pathway.
RESUMO
Objective: To investigate the relationship between nutritional risk status and clinical outcome in children with tuberculous meningitis (TBM). Methods: The clinical data (basic information, clinical symptoms and laboratory test results) of 112 patients with TBM, who were admitted to Department of Pediatric Infectious Diseases of West China Second Hospital of Sichuan University,from January 2013 to December 2020 were retrospectively analyzed. The patients were divided into the nutritional risk group and the non-nutritional risk group according to the assessment of the nutritional risk by the STRONGkids Scale. The variables of basic information, clinical symptoms and laboratory test measurements etc. were compared between the two groups by using Student t test, Rank sum test or Chi-square test. Multivariate Logistic regression analysis were used to analyze nutritional risk factors. Results: Among 112 patient with TBM, 55 were males and 57 females. There were 62 cases in the nutritional risk group and 50 cases in the non-nutritional risk group. The proportion of cases with nutritional risk was 55.4% (62/112). Patients in the nutritional risk who lived in rural areas, had symptoms of brain nerve damage, convulsions, emaciation and anorexia, with a diagnosis time of ≥21 days, and the level of cerebrospinal fluid (CSF) protein were all higher than those in the non-nutritional risk group ((50 cases (80.6%) vs. 32 cases (64.0%), 20 cases (32.3%) vs.8 cases (16.0%), 33 cases (53.2%) vs. 15 cases (30.0%), 30 cases (48.4%) vs. 2 cases (4.0%), 59 cases (95.2%) vs. 1 case (2.0%),41 cases (66.1%) vs.18 cases (36.0%), 1 406 (1 079, 2 068) vs. 929 (683, 1 208) mg/L, χ2=3.91, 3.90, 6.10, 26.72, 98.58, 10.08, Z=4.35, all P<0.05). The levels of serum albumin,hemoglobin,lymphocyte count, white blood cell count, and CSF glucose were significantly lower in patients with nutritional risk ((36±5) vs. (41±4) g/L, (110±17) vs. (122±14) g/L, 1.4 (1.0, 2.0)vs. 2.3 (1.6, 3.8)×109/L, 7.8 (6.3, 10.0)×109 vs. 10.0 (8.3, 12.8)×109/L, 1.0 (0.8, 1.6) vs. 2.1 (1.3, 2.5) mmol/L, t=-6.15, -4.22, Z=-4.86, -3.92, -4.16, all P<0.05).Increased levels of serum albumin (OR=0.812, 95%CI:0.705-0.935, P=0.004) and lymphocyte count (OR=0.609, 95%CI:0.383-0.970, P=0.037) may reduce the nutritional risk of children with TBM; while convulsions (OR=3.853, 95%CI:1.116-13.308, P=0.033) and increased level of CSF protein (OR=1.001,95%CI:1.000-1.002, P=0.015) may increase the nutritional risk of children with TBM. Similarly, the rate of complications and drug-induced liver injury was higher in the nutritional risk group (47 cases (75.8%) vs. 15 cases(30.0%), 31 cases (50.0%) vs.8 cases (16.0%), χ2=23.50, 14.10, all P<0.05). Moreover, the length of hospital stay was also longer in the nutritional risk group ((27±13) vs. (18±7) d, t=4.38, P<0.05). Conclusions: Children with TBM have a high incidence of nutritional risk. Convulsive, the level of serum albumin, the level of lymphocyte count and CSF protein may affect the nutritional risk of children with TBM. The nutritional risk group has a high incidence of complications and heavy economic burden.It is necessary to carry out nutritional screening and nutritional support for children with TBM as early as possible.

RESUMO
BACKGROUND@#Psoriasis is a common, chronic, immune-mediated inflammatory skin disease with increased epidermal proliferation. The objective of this review was to systematically identify the evidence and perform a network meta-analysis (NMA) to estimate the relative efficacy of secukinumab (SEC) against adalimumab (ADA) and infliximab (INF) for the treatment of moderate-to-severe plaque psoriasis.@*METHODS@#A systematic literature review (SLR) was conducted according to a pre-specified protocol to identify relevant studies. Initially, the databases were searched from database inception till June 2013, and the SLR was updated in April 2020. The eligibility criteria included adult patients (≥18 years old) with moderate-to-severe plaque psoriasis, and the SLR included randomized controlled trials (RCTs). The comparators of interest were SEC, ADA, INF, and placebo (PLA), while outcomes of interest were Psoriasis Area and Severity Index (PASI) (50, 75, and 90) at weeks 12, 16, and 24. A Bayesian NMA for PASI was utilized with a framework that evaluated the probability of PASI responses in different categories of PASI thresholds within a single model.@*RESULTS@#A total of 23 RCTs that assessed the efficacy of SEC, ADA, and INF in patients with moderate-to-severe plaque psoriasis were identified. At 12 weeks, SEC was associated with a significantly better response compared with PLA and ADA for PASI 75 and 90, while response results were comparable against INF. At 12 weeks, risk ratio (95% confidence interval) derived from NMA for SEC vs. ADA and INF for PASI 75 was 1.35 (1.19, 1.57) and 1.01 (0.90, 1.18), respectively. At the 16-week and 24-week time interval, SEC was significantly better than PLA, ADA, and INF for PASI 75 and 90.@*CONCLUSION@#Efficacy of SEC in the treatment of patient populations with moderate-to-severe plaque psoriasis is well demonstrated through NMA.

The permeation and pharmacodynamics of ocular drugs are influenced by the corneal barrier. Here, a hard-soluble drug, brinzolamide, was selected as the model drug and used for preparation of minimally invasive dissolving microneedles. Brinzolamide was dissolved in ethanol and polyvinylpyrrolidone (PVP) K90 was added and dissolved. The mixture solution was casted into the dissolving microneedles mold and dried and brinzolamide dissolving microneedles (BMN) were obtained after demolding. The stereoscopic and scanning electron microscopic images showed that BMN were conical needles with the height of 750 μm, the bottom diameter of 300 μm, and the inter-tip distance of 500 μm. The dissolving microneedles patch was composed of 10×10 arrays with the area of 1 cm2 and the high drug load of 7.3 mg·cm-2. BMN showed a rapid in vitro drug release with 93% accumulative release at 2 h and the high drug corneal permeation amount of 877 ± 105 μg. BMN exhibited the high mechanical strength of 0.32 N/needle, leading to easy rat corneal insertion with the depth of 200 μm. Moreover, BMN were rapidly dissolved in the cornea, and more importantly, the damaged cornea were quickly self-healed within 24 h. Animal experiments were approved by the Ethics Committee of Beijing Institute of Radiation Medicine, Academy of Military Medical and the experiments were conducted in accordance with relevant guidelines and regulations. Ocular minimally invasive dissolving microneedles have the advantages of corneal minimal wounds and rapid healing, high drug loading, and high permeability, favoring the treatment of ocular diseases.

RESUMO
Objective@#To explore the clinical characteristics of drug-resistant tuberculosis (TB) in children and to study the effectiveness of second-line anti-TB therapy for children and to examine the incidence of adverse drug reactions.@*Method@#Retrospective research was conducted. The clinical records of children in West China Second Hospital diagnosed as drug-resistant TB from January 2010 to June 2014 were investigated.The clinical characteristics and risk factors were analyzed retrospectively. Treatment effect at discharge was examined as a short-term outcome indicator to evaluate the effectiveness of second-line anti-TB therapy and the incidence of adverse drug reactions. χ2 test was used.@*Result@#Forty-six patients were diagnosed as drug-resistant TB in 443 children infected with TB, with a 10.4% resistance rate. The 46 children included 26 male and 20 female patients, aged from one month and 28 days to 17 years and 5 months, with the average age (8.4±4.5) years, >7 to 14 years old patients as the biggest part(25 patients, 54.3%). Among the 46 children, 20 patients(43.5%)had close contact with TB patients, of whom 12 patients (60.0%) contacted with family members (including parents, brothers and sisters and grandparents living together) and 8 patients(40.0%) contacted with patients from outside family (such as relatives or neighbors). Moreover, 11 cases (23.9%) were under initial treatment and 35 cases (76.1%) were retreated.From 2010 to 2014, the number of cases of initial and retreated patients had no significant difference(0 and 1, 1 and 13, 4 and 7, 4 and 11, 2 and 3 cases, χ2=3.255, P=0.196). Among retreated patients, 31.4% (11/35) had irregular treatment before.Until discharge, the effective rate was 87.0% (40/46), while the incidence rate of adverse drug reaction was 10.9%(5/46).@*Conclusion@#The therapy for drug-resistant TB is effective and the incidence of adverse drug reaction is relatively low.
RESUMO
<p><b>OBJECTIVE</b>To investigate the clinical features of invasive fungal disease (IFD) in children without underlying diseases.</p><p><b>METHODS</b>The clinical data of 49 children without underlying diseases who were diagnosed with IFD were retrospectively studied.</p><p><b>RESULTS</b>Fungal pathogens were detected in 37 (76%) out of 49 patients, including Cryptococcus neoformans (17 children, 46%), Candida albicans (10 children, 27%), Aspergillus (3 children, 8%), and Candida parapsilosis (3 children, 8%). Fungal pneumonia (17 children, 46%) was the most commonly seen disease, with Candida albicans as the major pathogen (9 children, 53%). The 49 children had at least one high-risk factor for infection, including the use of antibiotics, a long length of hospital stay, and invasive procedures. Of all the children, 82% did not respond well to antibiotic treatment or experienced recurrent pyrexia. Among the 24 children who underwent G tests, 17 (71%) showed positive results. All the children were given antifungal therapy, and among these children, 37 (75%)were cured, 3 (6%) were still in the treatment, 5 (10%) died, and 4 (8%) were lost to follow-up.</p><p><b>CONCLUSIONS</b>In IFD children without underlying diseases, Cryptococcus neoformans and Candida are the main pathogens, and lung infection is the most common disease. Long-term use of high-dose antibiotics may be an important risk factor for fungal infection. The IFD children without underlying diseases are sensitive to antifungal drugs and have a satisfactory prognosis.</p>

Stroke research and rehabilitation have traditionally focused on the physical and functional impact of a stroke. Less attention has been given to the psychosocial factors associated with this chronic condition. By the few studies that have specifically focused on psychosocial factors in the context of stroke, poststroke depression is demonstrated to significantly influence stroke outcomes. Associations of stroke with psychological symptoms other than depression have rarely been evaluated. This study was aimed to investigate the changes of psychological stress, social support and medication adherence in patients with ischemic stroke in the mainland of China. In this study, 90 patients with hemiplegia one year after first-ever middle cerebral artery infarction (stroke group) in the Zhongnan Hospital of Wuhan University from June 2008 to June 2011 were recruited for interview. Ninety age- and sex-matched normal volunteers (control group) were also examined at the same period. The psychological distress was assessed by the Symptom Checklist 90 (SCL-90), the social support by the Social Support Rating Scale (SSRS), and medication adherence by Morisky's self-reported inventory, respectively. Group differences were analyzed using unpaired-t test and chi-squared test. The results showed that total mean scores of the SCL-90 in the stroke group were higher than those in the control group (P<0.01). Except two dimensions, paranoid ideation and psychoticism, mean scores of the rest dimensions (including somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, and phobic anxiety) of SCL-90 were significantly higher in the stroke group than those in the control group (P<0.05, or P<0.01). The objective support, subjective support, support availability and total social support scores in the stroke group were significantly higher than those in the control group (P<0.05, or P<0.01). Those in the "SCL-90 total scores >150 group" were significantly higher than in the "SCL-90 total scores <100 group" and the "SCL-90 total scores between 100 to 150 group" (P<0.05, or P<0.01). Those in the "SCL-90 total scores between 100 to 150 group" were significantly higher than in the "SCL-90 total scores <100 group" (P<0.05). In 90 patients with ischemic stroke, 26 (28.89%) patients obtained high medication adherence, 47 (52.22%) patients medium medication adherence, and 17 (18.89%) patients low medication adherence, respectively. Among these stroke patients, there were 17 (50.00%) patients with high medication adherence in the "SCL-90 total scores >150 group", 28 (75.67%) patients with medium medication adherence in the "SCL-90 total scores between 100 to 150 group", and 12 (61.16%) patients with low medication adherence in the "SCL-90 total scores <100 group", respectively. There was significant difference in the medication adherence rate among the different SCL-90 scores groups in these stroke patients (P<0.05 or P<0.01). It was led to conclude that ischemic stroke patients one year after hemiplegia have psychological distress, low level of social support and poor medication adherence in the mainland of China. Therefore, it is necessary to mobilize the government, medical institutions and various social support groups to offer psychological interventions to relieve the stress of patients with ischemic stroke, and improve their medication adherence.
