Effectiveness of fentanyl buccal soluble film in cancer patients with inadequate breakthrough pain control.

BACKGROUND: Clinical evidence for the rapidity and effectiveness of fentanyl buccal soluble film (FBSF) in reducing pain intensity of breakthrough cancer pain (BTcP) remains inadequate. This study aimed to evaluate the efficacy of FBSF proportional to the around-the-clock (ATC) opioid regimens in rapidly relieving the intensity of BTcP episodes by determining the percentage of patients requiring further dose titration. METHODS: The study procedure included a dose-finding period followed by a 14-day observation period. Pain intensity was recorded with a Numeric Rating Scale (NRS) at onset and 5, 10, 15, and 30 min after FBSF self-administration. Meaningful pain relief was defined as the final NRS score ≤ 3. Satisfaction survey was conducted for each patient after treatment using the Global Satisfaction Scale. RESULTS: A total of 63 BTcP episodes occurred in 30 cancer patients. Only one patient required rescue medication at first BTcP episode and then achieved meaningful pain relief after titrating FBSF by 200 µg. Most BTcP episodes relieved within 10 min. Of 63 BTcP episodes, 30 (47.6%), 46 (73.0%), and 53 (84.1%) relieved within 5, 10, and 15 min after FBSF administration. Only grade 1/2 adverse events were reported, including somnolence, malaise, and dizziness. Of the 63 BTcP episodes, 82.6% were rated as excellent/good satisfaction with FBSF. CONCLUSION: FBSF can be administrated "on demand" by cancer patients at the onset of BTcP, providing rapid analgesia by achieving meaningful pain relief within 10 min. TRIAL REGISTRATION: This study was retrospectively registered 24 December, 2021 at Clinicaltrial.gov (NCT05209906): https://clinicaltrials.gov/study/NCT05209906 .

The role of nutrition in analysis of risk factors and short-term outcomes for late-onset necrotizing enterocolitis among very preterm infants: a nationwide, multicenter study in China.

BACKGROUND: Necrotizing enterocolitis (NEC) is a serious gastrointestinal disease, primarily affects preterm newborns and occurs after 7 days of life (late-onset NEC, LO-NEC). Unfortunately, over the past several decades, not much progress has been made in its treatment or prevention. This study aimed to analyze the risk factors for LO-NEC, and the impact of LO-NEC on short-term outcomes in very preterm infants (VPIs) with a focus on nutrition and different onset times. METHOD: Clinical data of VPIs were retrospectively collected from 28 hospitals in seven different regions of China from September 2019 to December 2020. A total of 2509 enrolled VPIs were divided into 2 groups: the LO-NEC group and non-LO-NEC group. The LO-NEC group was divided into 2 subgroups based on the onset time: LO-NEC occurring between 8 ~ 14d group and LO-NEC occurring after 14d group. Clinical characteristics, nutritional status, and the short-term clinical outcomes were analyzed and compared among these groups. RESULTS: Compared with the non-LO-NEC group, the LO-NEC group had a higher proportion of anemia, blood transfusion, and invasive mechanical ventilation (IMV) treatments before NEC; the LO-NEC group infants had a longer fasting time, required longer duration to achieve the target total caloric intake (110 kcal/kg) and regain birthweight, and showed slower weight growth velocity; the cumulative dose of the medium-chain and long-chain triglyceride (MCT/LCT) emulsion intake in the first week after birth was higher and breastfeeding rate was lower. Additionally, similar results including a higher proportion of IMV, lower breastfeeding rate, more MCT/LCT emulsion intake, slower growth velocity were also found in the LO-NEC group occurring between 8 ~ 14d when compared to the LO-NEC group occurring after 14 d (all (P < 0.05). After adjustment for the confounding factors, high proportion of breastfeeding were identified as protective factors and long fasting time before NEC were identified as risk factors for LO-NEC; early feeding were identified as protective factors and low gestational age, grade III ~ IV neonatal respiratory distress syndrome (NRDS), high accumulation of the MCT/LCT emulsion in the first week were identified as risk factors for LO-NEC occurring between 8 ~ 14d. Logistic regression analysis showed that LO-NEC was a risk factor for late-onset sepsis, parenteral nutrition-associated cholestasis, metabolic bone disease of prematurity, and extrauterine growth retardation. CONCLUSION: Actively preventing premature birth, standardizing the treatment of grade III ~ IV NRDS, and optimizing enteral and parenteral nutrition strategies may help reduce the risk of LO-NEC, especially those occurring between 8 ~ 14d, which may further ameliorate the short-term clinical outcome of VPIs.

Noninvasive Diagnostic Technique for Nonalcoholic Fatty Liver Disease Based on Features of Tongue Images / 中国结合医学杂志

OBJECTIVE@#To investigate a new noninvasive diagnostic model for nonalcoholic fatty liver disease (NAFLD) based on features of tongue images.@*METHODS@#Healthy controls and volunteers confirmed to have NAFLD by liver ultrasound were recruited from China-Japan Friendship Hospital between September 2018 and May 2019, then the anthropometric indexes and sampled tongue images were measured. The tongue images were labeled by features, based on a brief protocol, without knowing any other clinical data, after a series of corrections and data cleaning. The algorithm was trained on images using labels and several anthropometric indexes for inputs, utilizing machine learning technology. Finally, a logistic regression algorithm and a decision tree model were constructed as 2 diagnostic models for NAFLD.@*RESULTS@#A total of 720 subjects were enrolled in this study, including 432 patients with NAFLD and 288 healthy volunteers. Of them, 482 were randomly allocated into the training set and 238 into the validation set. The diagnostic model based on logistic regression exhibited excellent performance: in validation set, it achieved an accuracy of 86.98%, sensitivity of 91.43%, and specificity of 80.61%; with an area under the curve (AUC) of 0.93 [95% confidence interval (CI) 0.68-0.98]. The decision tree model achieved an accuracy of 81.09%, sensitivity of 91.43%, and specificity of 66.33%; with an AUC of 0.89 (95% CI 0.66-0.92) in validation set.@*CONCLUSIONS@#The features of tongue images were associated with NAFLD. Both the 2 diagnostic models, which would be convenient, noninvasive, lightweight, rapid, and inexpensive technical references for early screening, can accurately distinguish NAFLD and are worth further study.

Exploring the oral-gut microbiota during thyroid cancer: Factors affecting the thyroid functions and cancer development.

Thyroid cancer (TC) is categorized into papillary, follicular, medullary, and anaplastic. The TC is increasing in several countries, including China, the United States, the United Kingdom, Canada, France, Australia, Germany, Japan, Spain, and Italy. Thus, this review comprehensively covers the factors that affect thyroid gland function, TC types, risk factors, and symptoms. Lifestyle factors (such as nutrient consumption and smoking) and pollutants (such as chemicals and heavy metals) increased the thyroid-stimulating hormone (TSH) levels which are directly related to TC prevalence. The conventional and recent TC treatments are also highlighted. The role of the oral and gut microbiota as well as the application of probiotics on TC are also discussed. The variations in the composition of oral and gut microbes influence the thyroid function indirectly through alteration in metabolites (such as short-chain fatty acids) that are eminent for cellular energy metabolism. Maintenance of healthy gut and oral microbiota can help in regulating thyroid function by regulating iodine uptake. Oral or gut microbial dysbiosis can be considered as an early diagnosis factor or TC marker. High TSH during TC can increase the oral microbial diversity while disrupting the high ratio of Firmicutes and Bacteroidetes in the gut. Supplementation of probiotics as an adjuvant in TC treatment is beneficial. However, needs more extensive research to explore the direct effect of probiotics on thyroid function.

Real-Time Tracking of Laryngeal Motion via the Surface Depth-Sensing Technique for Radiotherapy in Laryngeal Cancer Patients.

Radiotherapy (RT) is an important modality for laryngeal cancer treatment to preserve laryngeal function. During beam delivery, laryngeal motion remains uncontrollable and may compromise tumor-targeting efficacy. We aimed to examine real-time laryngeal motion by developing a surface depth-sensing technique with preliminary testing during RT-based treatment of patients with laryngeal cancer. A surface depth-sensing (SDS) camera was set up and integrated into RT simulation procedures. By recording the natural swallowing of patients, SDS calculation was performed using the Pose Estimation Model and deep neural network technique. Seven male patients with laryngeal cancer were enrolled in this prospective study. The calculated motion distances of the laryngeal prominence (mean ± standard deviation) were 1.6 ± 0.8 mm, 21.4 ± 5.1 mm, 6.4 ± 3.3 mm, and 22.7 ± 4.9 mm in the left-right, cranio-caudal, and anterior-posterior directions and for the spatial displacement, respectively. The calculated differences in the 3D margins for generating the planning tumor volume by senior physicians with and without SDS data were -0.7 ± 1.0 mm (-18%), 11.3 ± 6.8 mm (235%), and 1.8 ± 2.6 mm (45%) in the left-right, cranio-caudal, and anterior-posterior directions, respectively. The SDS technique developed for detecting laryngeal motion during swallowing may be a practical guide for individualized RT design in the treatment of laryngeal cancer.

Rapid synthesis of BaMoO4 :Eu3+ red phosphors using microwave irradiation.

This study synthesized BaMoO4:Eu3+ red phosphors using the microwave method. In addition, the phase composition, morphology, and luminescence properties of the red phosphors were characterized using X-ray diffraction, field-scanning electron microscopy, and photoluminescence spectroscopy. The results revealed that doping red phosphors with different concentrations of Eu3+ does not change the crystal structure of the matrix material. The BaMoO4 :Eu3+ phosphors exhibited micron-scale irregular polyhedra, which could be excited by ultraviolet light with a wavelength of 395 nm to induce red-light emission. The optimal dosage of Eu3+ was 0.08, and the chromaticity coordinates of BaMoO4 :0.08Eu3+ phosphors were (0.5869, 0.3099). White light-emitting diode (w-LED) devices manufactured by using a combination of BaMoO4 :0.08Eu3+ phosphor and commercially available phosphors exhibited good white-light emission under the excitation of an ultraviolet chip. The BaMoO4 :0.08Eu3+ red phosphors that rapidly synthesized under the microwave field are expected to be used in w-LED devices.

Study on the preparation and luminescence properties of SrGe4 O9 :Mn4+ red phosphors for plant illumination.

In this study, SrGe4 O9 :Mn4+ red phosphors for plant illumination were prepared using a high-temperature solid-phase method. The samples were characterized and analyzed by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), fluorescence spectroscopy, and other techniques. The phase structure, apparent morphology, and luminescence properties of the SrGe4 O9 :Mn4+ red phosphors were investigated. The results indicated that the dopant Mn4+ was incorporated into the matrix structure by substituting some Ge4+ ions without any changes in the crystal structure of the SrGe4 O9 matrix. The samples comprised micron-scale particles and exhibited high purity and uniform distribution of elements. The SrGe4 O9 :Mn4+ phosphors exhibited relatively strong red light emission at 660 nm under the excitation of a 430-nm blue light, and the luminescence intensity was the highest when the Mn4+ doping amount was 1%. Proper doping of Ti4+ or Sn4+ could effectively improve the luminescence intensity of the SrGe4 O9 :Mn4+ phosphors. The light-emitting diode (LED) device packaging showed that the SrGe4 O9 :Mn4+ red phosphors could be used for plant growth illumination.

AIM:To analyze the efficacy of modified pterygium resection combined with conjunctival autograft transplantation(CAT)in the treatment of pterygium.METHODS: A total of 140 patients(154 eyes)with pterygium treated in the ophthalmology department of our hospital from January 2018 to January 2021 were selected and grouped according to random number table method. In the observation group, 70 cases(76 eyes)were treated with modified pterygium excision combined with CAT, and improved iris restorer was used during the operation. In the control group, 70 patients(78 eyes)were treated with conventional pterygium excision combined with CAT, during which traditional iris restorer was used. Follow up for 1a, the postoperative vision, subjective symptoms, conjunctival signs(conjunctival congestion and chemosis), corneal epithelial healing, postoperative complications and recurrence rate were compared between the two groups.RESULTS: Compared with pre-operation, vision of the two groups decreased significantly on 1, 3 and 5d after operation(P&#x0026;#x003C;0.05), while there was no statistically significant difference between the groups(P&#x0026;#x003E;0.05). Compared with 1d after operation, the scores on subjective symptoms, conjunctival hyperemia and edema in the two groups decreased significantly on 3, 5 and 14d after operation(P&#x0026;#x003C;0.05), and those scores of the observation group on 3, 5 and 14d after operation were significantly lower than those of control group(P&#x0026;#x003C;0.05).The corneal fluorescein staining(FL)scores of the observation group on 3, 5 and 14d after operation were significantly lower than those of the control group(P&#x0026;#x003C;0.05). The proportion of repair time of corneal epithelial defect ≤5d in the observation group was significantly higher than that in the control group(P&#x0026;#x003C;0.05). The incidence rates of conjunctival granuloma, symblepharon, and the recurrence rate in the observation group were significantly lower than those in the control group(P&#x0026;#x003C;0.05).CONCLUSION: Modified pterygium resection combined with CAT is effective in the treatment of pterygium, which can alleviate postoperative irritative symptoms, conjunctival congestion and edema, and it is more conducive to postoperative corneal epithelial reconstruction, reduction of postoperative complications and recurrence rate.

Prophylactic Penehyclidine Inhalation for Prevention of Postoperative Pulmonary Complications in High-risk Patients: A Double-blind Randomized Trial.

BACKGROUND: Postoperative pulmonary complications are common. Aging and respiratory disease provoke airway hyperresponsiveness, high-risk surgery induces diaphragmatic dysfunction, and general anesthesia contributes to atelectasis and peripheral airway injury. This study therefore tested the hypothesis that inhalation of penehyclidine, a long-acting muscarinic antagonist, reduces the incidence of pulmonary complications in high-risk patients over the initial 30 postoperative days. METHODS: This single-center double-blind trial enrolled 864 patients age over 50 yr who were scheduled for major upper-abdominal or noncardiac thoracic surgery lasting 2 h or more and who had an Assess Respiratory Risk in Surgical Patients in Catalonia score of 45 or higher. The patients were randomly assigned to placebo or prophylactic penehyclidine inhalation from the night before surgery through postoperative day 2 at 12-h intervals. The primary outcome was the incidence of a composite of pulmonary complications within 30 postoperative days, including respiratory infection, respiratory failure, pleural effusion, atelectasis, pneumothorax, bronchospasm, and aspiration pneumonitis. RESULTS: A total of 826 patients (mean age, 64 yr; 63% male) were included in the intention-to-treat analysis. A composite of pulmonary complications was less common in patients assigned to penehyclidine (18.9% [79 of 417]) than those receiving the placebo (26.4% [108 of 409]; relative risk, 0.72; 95% CI, 0.56 to 0.93; P = 0.010; number needed to treat, 13). Bronchospasm was less common in penehyclidine than placebo patients: 1.4% (6 of 417) versus 4.4% (18 of 409; relative risk, 0.327; 95% CI, 0.131 to 0.82; P = 0.011). None of the other individual pulmonary complications differed significantly. Peak airway pressures greater than 40 cm H2O were also less common in patients given penehyclidine: 1.9% (8 of 432) versus 4.9% (21 of 432; relative risk, 0.381; 95% CI, 0.171 to 0.85; P = 0.014). The incidence of other adverse events, including dry mouth and delirium, that were potentially related to penehyclidine inhalation did not differ between the groups. CONCLUSIONS: In high-risk patients having major upper-abdominal or noncardiac thoracic surgery, prophylactic penehyclidine inhalation reduced the incidence of pulmonary complications without provoking complications.

Delta-volume radiomics of induction chemotherapy to predict outcome of subsequent chemoradiotherapy for locally advanced hypopharyngeal cancer.

INTRODUCTION: Induction chemotherapy (IC) followed by concurrent chemoradiotherapy (CCRT) is recommended for larynx-preserving treatment of locally advanced hypopharyngeal cancer (LAHC). However, the conventional evaluation of response is not robust enough to predict the outcome of subsequent treatments. This study aimed to develop an imaging biomarker using changes in radiomic features in invasive tumor front (ITF) by IC to predict treatment outcome of subsequent CCRT in LAHC. METHODS: From 2006 to 2018, 59 computed tomography (CT) scan images before and after IC in patients with LAHC were used to contour the gross tumor volumes (GTVs). A total of 48 delta-volume radiomics features were acquired from the absolute spatial difference of GTVs (delta-GTV) before and after IC, conceptually representing a consistent portion of ITF. Least absolute shrinkage and selection operator regression (LASSO) was used to select features for establishing the model generating radiomic score (R score). RESULTS: A model including 5 radiomic features from delta-GTV to predict better progression-free survival (PFS) of patients receiving subsequent CCRT was established. The R score was validated with all datasets (area under the curve 0.77). Low R score (<-0.16) was associated with improved PFS (p < 0.05). CONCLUSIONS: The established radiomic model for ITF from radiomic features of delta-GTV after IC might be a potential imaging biomarker for predicting clinical outcome of subsequent CCRT in LAHC.

Screening of differentially expressed genes for colorectal cancer and prediction of potential traditional Chinese medicine: based on bioinformatics / 中国中药杂志

This study screened and analyzed the differentially expressed genes(DEGs) between colorectal cancer(CRC) tissues and normal tissues with bioinformatics techniques to predict biomarkers and Chinese medicinals for the diagnosis and treatment of CRC. The microarray data sets GSE21815, GSE106582, and GSE41657 were downloaded from the Gene Expression Omnibus(GEO), and the DEGs were screened by GEO2 R, followed by the Gene Ontology(GO) tern enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis of the DEGs based on DAVID. The protein-protein interaction network was constructed by STRING, and MCODE and Cytohubba plug-ins were used to screen the significant modules and hub genes in the network. UCSC, cBioPortal, and Oncomine were employed for hierarchical clustering, survival analysis, Oncomine analysis, and correlation analysis of clinical data. Coremine Medical was applied to predict the Chinese medicinals acting on hub genes. A total of 284 DEGs were screened out, with 146 up-regulated and 138 down-regulated. The up-regulated genes were mainly involved in cell cycle, NLRs pathway, and TNF signaling pathway, and the down-regulated genes were related to mineral absorption, nitrogen metabolism, and bicarbonate reabsorption in proximal tubules. The 15 hub genes were CDK1, CDC20, AURKA, MELK, TOP2 A, PTTG1, BUB1, CDCA5, CDC45, TPX2, NEK2, CEP55, CENPN, TRIP13, and GINS2, among which CDK1 and CDC20 were regarded as core genes. The high expression of CDK1 and CDC20 suggested poor prognosis, and they significantly expressed in many cancers, especially breast cancer, lung cancer, and CRC. The expression of CDK1 and CDC20 was correlated with gender, tumor type, TNM stage, and KRAS gene mutation. The potential effective medicinals against CRC were Scutellariae Radix, Scutellariae Barbatae Herba, Arnebiae Radix, etc. The significant expression of CDK1 and CDC20 can help distinguish tumor tissues from normal tissues, and is related to survival prognosis. Thus, the two can be used as biomarkers for the diagnosis and treatment of CRC. This study provides a reference for related drug development.

Pediatric SMARCB1/INI1-deficient poorly differentiated chordoma of the skull base: report of five cases and review of literature / 中华病理学杂志

Objective: To investigate the clinicopathological characteristics and differential diagnosis of pediatric SMARCB1/INI1-deficient poorly differentiated chordoma (PDC) of the skull base. Methods: Five cases of SMARCB1/INI1-deficient PDC were identified in 139 cases of chordoma diagnosed in Sanbo Brain Institute, Capital Medical University, Beijing, China from March 2017 to March 2021. The clinical and imaging data of the 5 PDCs were collected. H&E and immunohistochemical staining, and DNA methylation array were used, and the relevant literatures were reviewed. Results: All 5 PDCs were located at the clivus. The average age of the patients was 6.4 years, ranging from 3 to 16 years. Three patients were female and two were male. Morphologically, in contrast with classical chordomas, they presented as epithelioid or spindle tumor cells organized in sheets or nests, with necrosis, active mitoses, and infiltration into surrounding tissue. All cases showed positivity of CKpan, EMA, vimentin and brachyury (nuclear stain), and loss of nuclear SMARCB1/INI1 expression. S-100 protein expression was not frequent (2/5). Ki-67 proliferative index was high (20%-50%). All cases had over-expressed p53. It was necessary to differentiate SMARCB1/INI1-dificient PDC from SMARCB1/INI1-dificient tumors occurring at skull base of children or the tumors with epithelial and spindle cell morphological features. The 3 PDCs with DNA methylation testing showed the methylation profiles different from the pediatric atypical teratoid/rhabdoid tumors. They formed an independent methylation profile cluster. The clinical prognosis of the 5 patients was poor, and the overall survival time was 2-17 months. Conclusions: PDC is a special subtype of chordoma, which often affects children and occurs in the clivus. The PDC shares epithelioid or spindle cell morphologic features which are different from the classic chordoma. Besides the typical immunohistochemical profile of chordoma, PDC also has loss of nuclear SMARCB1/INI1 expression and distinct epigenetic characteristics.

AIM:To explore the effect of base curve aspheric orthokeratology lens in the treatment of adolescents with myopia and moderate to high astigmatism, and its influence on ocular surface morphology and tears.METHODS:A total of 232 adolescents(464 eyes)with myopia and moderate to high astigmatism treated in the hospital from December 2018 to March 2020 were selected as the research subjects. They were randomly divided into control group(116 patients, 232 eyes)and observation group(116 patients, 232 eyes). The control group was treated with base curve spheric orthokeratology lens, while the observation group was treated with base curve aspheric orthokeratology lens. Comparison was made between the two groups in terms of the correction effect, objective visual quality, ocular surface morphology, tears related indicators before and after wearing the lenses, and the incidence of complications after wearing the lenses for 12mo.RESULTS:After wearing the lenses, the uncorrected visual acuity(UCVA)and diopter of the two groups were significantly improved. The UCVA and diopter of the observation group were significantly better than those of the control group(all P&#x003C;0.05). After wearing the lenses, the whole-eye and corneal coma, spherical aberrations and high-order aberrations were significantly increased, while Strehl ratio and modulation transfer function were decreased in the two groups. Trefoil aberrations was significantly increased(all P&#x003C;0.05). These indicators in the observation group were better than those in the control group(all P&#x003C;0.05). After wearing the lenses, the epithelium fluorescence staining scores, ocular surface disease index(OSDI)scores were significantly decreased in the two groups(P&#x003C;0.05), but there was no statistically significant difference between the two groups(P&#x003E;0.05); The noninvasive tear breakup time(NI-BUT)of the two groups were significantly decreased after wearing the lenses(P&#x003C;0.05), but there was no statistically significant difference between the two groups(P&#x003E;0.05). The Schirmer Ⅰ test and tear meniscus height of the two groups showed no statistically significant difference before and after wearing the lenses(P&#x003E;0.05). The incidence rates of complications in the observation group and the control group after wearing the lenses were close(6.9% vs 6.0%, P &#x003E;0.05).CONCLUSION:Base curve aspheric orthokeratology lens is superior to base curve spheric orthokeratology lens in the treatment of adolescents with myopia and moderate to high astigmatism in terms of correction effect and objective visual quality. The two lenses have similar influence on ocular surface morphology and tears.

A severe case of human coronavirus 229E pneumonia in an elderly man with diabetes mellitus: a case report.

BACKGROUND: With pandemic of coronavirus disease 2019 (COVID-19), human coronaviruses (HCoVs) have recently attached worldwide attention as essential pathogens in respiratory infection. HCoV-229E has been described as a rare cause of lower respiratory infection in immunocompetent adults. CASE PRESENTATION: We reported a 72-year-old man infected by HCoV-229E with rapid progression to acute respiratory distress syndrome, in conjunction with new onset atrial fibrillation, intensive care unit acquired weakness, and recurrent hospital acquired pneumonia. Clinical and radiological data were continuously collected. The absolute number of peripheral T cells and the level of complement components diminished initially and recovered after 2 months. The patient was successfully treated under intensive support care and discharged from the hospital after 3 months and followed. CONCLUSION: HCoV-229E might an essential causative agent of pulmonary inflammation and extensive lung damage. Supportive treatment was essential to HCoVs infection on account of a long duration of immunological recovery in critical HCoV-229E infection.

Sarcopenia and Systemic Inflammation Synergistically Impact Survival in Oral Cavity Cancer.

OBJECTIVES: Sarcopenia and systemic inflammation can affect survival of advanced-stage oral squamous cell carcinoma (OSCC) patients; however, their reciprocal associations with survival outcomes are yet to be investigated. STUDY DESIGN: Retrospective review at a tertiary cancer center. METHODS: Patients with stage III-IVB OSCC that underwent surgery and (chemo)radiotherapy at our institution between 2010 and 2015 were reviewed. Skeletal muscle index (SMI) was assessed using computed tomography scans at the C3 vertebra. Sarcopenia was defined at the lowest sex-specific tertile for SMI. Systemic inflammation was estimated using the modified Glasgow prognostic score (mGPS), which ranges from 0 to 2 based on serum C-reactive protein and albumin levels. The predictors of overall survival (OS) were evaluated using Cox regression models. RESULTS: A total of 174 patients were included in the study. The cut-off values for sarcopenia were set at SMI <52.4 cm2 /m2 (men) and < 36.2 cm2 /m2 (women) corresponding to the lowest sex-specific tertile. An mGPS 1-2 was independently associated with sarcopenia (odds ratio: 2.05; 95% confidence interval: 1.06-3.97; P = .03). On multivariate analysis for OS, sarcopenia and mGPS 1-2 independently predicted OS (hazard ratio: 2.12; 95% confidence interval: 1.17-3.85; P = .01 and hazard ratio: 7.85; 95% confidence interval: 3.7-16.65; P < .001, respectively). Patients with both sarcopenia and mGPS 1-2 (vs. neither) had worse OS (hazard ratio: 16.80; 95% confidence interval: 6.01-46.99; P < .001). CONCLUSIONS: Sarcopenia and systemic inflammation may exert a negative synergistic prognostic impact in advanced-stage OSCC patients. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E1530-E1538, 2021.

An Exploration on Mechanisms of Treating Different Diseases with Same Method of Qinggan Huayu Granules in Treating NAFLD and Liver Cancer Based on Network Pharmacology / 中国实验方剂学杂志

Objective:To reveal the effective components， targets and possible mechanisms of Qinggan Huayu granules in the treatment of non-alcoholic fatty liver disease （NAFLD） and liver cancer based on network pharmacology and experimental verification， and to provide a basis for its rational interpretation of treating different diseases with same method for NAFLD and liver cancer. Method:Based on databases of traditional Chinese medicine and disease， the network pharmacology was used to screen main active compounds and potential targets of Qinggan Huayu granules for NAFLD and liver cancer. STRING 11.0 was used to analyze the interaction between potential targets. The core targets were selected from the interaction targets by cytoHubba plug-in. The gene ontology （GO） function and the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis were performed on the target by Metascape database. At the same time， <italic>in vitro</italic> experiments were conducted to validate the effect of kaempferol， one of the main active ingredients of Qinggan Huayu granules， on hepatocellular carcinoma cell model and NAFLD cell model. Result:A total of 43 potential targets of Qinggan Huayu granules for for NAFLD and liver cancer were screened， corresponding to 136 active ingredients in 8 herbal medicines. Through enrichment analysis of potential targets， there were 20 biological processes， 13 molecular functions， 9 cellular components and 15 signaling pathways. Qinggan Huayu granules regulated biological behaviors of tumors related to liver cancer and NAFLD （such as apoptosis inhibition and oxidative stress） mainly through kaempferol， quercetin， luteolin and other active ingredients for Caspase-3 （CASP3）， tumor protein p53 （TP53）， vascular endothelial growth factor A （VEGFA） and other hub genes. <italic>In vitro</italic> experiments revealed that kaempferol could inhibit cell proliferation in a dose-dependent manner in hepatocellular carcinoma cell model. And kaempferol could modulate the levels of malondialdehyde （MDA） and glutathione peroxidase （GPx）， which were the molecular markers of oxidative stress of NAFLD cell model. Kaempfero also regulated the expression level of CASP3 in hepatocellular carcinoma cell model and NAFLD cell model. Conclusion:The main mechanism of Qinggan Huayu granules in treating liver cancer and NAFLD with concept of treating different diseases with same method is related to systematic synergy effect of multiple compounds （represented by quercetin， luteolin and kaempferol）， multiple targets （represented by VEGFA， TP53 and CASP3） and multiple signaling pathways （represented by oxidative stress and cell apoptosis）.

Cryotherapy in Semirigid Thoracoscopy for Debridement of Multiloculated Empyema.

Surgical intervention is occasionally required for the treatment of pleural empyema. Semirigid thoracoscopy is a safe and successful surgical approach utilized by interventional pulmonologists, conventionally utilizing flexible forceps and suction as the main tools, but they can sometimes be inefficient for more complicated cases. In debriding a case of multiloculated empyema with semirigid thoracoscopy, we report the novel use of cryotherapy in clearing adhesions from the pleural cavity. We found using the cryoprobe to be more efficient than using forceps and suggest further investigation into its use in medical thoracoscopy.

Surgical histopathologic findings of 232 Chinese children cases with drug-resistant seizures.

OBJECTIVES: The drug-resistant seizures are characterized by frequent and severe onset of seizures in childhood. There is only little literature had extensively explored the types of pathological brain damage in Chinese children cases. The present study aims to investigate the histopathologic findings and seizure outcomes of drug-resistant seizures in cases of 0-14-year-old children. MATERIALS AND METHODS: About 232 children cases were retrospectively who underwent epilepsy surgery. The medical records, onset age, age of surgery, disease course, seizure type, pathological reports, and seizure outcomes of these patients were retrospectively analyzed. RESULTS: The most common categories were malformations of cortical development (focal cortical dysplasia (FCD) was the most common type (94.36%, 67/71), found in 30.60% of the patients, tumors in 18.11%, glial scar in 12.50%, and encephalitis in 11.63%). It was found that the effective seizure outcome of FCD cases with shorter duration of epilepsy (<2 years, 87.23%) was better than that with longer duration (≥2 years, 60.00%) and the difference was statistically significant (χ2  = 4.76, p < .05). Patients with FCD I, FCD II, and tumor showed the relatively better postsurgical seizure outcome than patients with other pathological types. CONCLUSION: The malformations of cortical development (MCD) (most FCD) were the most common pathological type for children cases in China with drug-resistant seizures. It was speculated further that the FCD patients with shorter duration of epilepsy before surgery seem to have a higher ratio of being seizure-free after surgery.

Neoadjuvant Chemoradiotherapy and Larynx-Preserving Surgery for Cervical Esophageal Cancer.

Neoadjuvant concurrent chemoradiotherapy (CCRT) followed by surgery is widely used for treating locally advanced esophageal cancer in the thorax. This study evaluated the feasibility of neoadjuvant CCRT as a larynx preservation strategy for treating cervical esophageal squamous cell carcinoma (SCC) by a multidisciplinary team. Fifteen patients with cervical esophageal SCC who received neoadjuvant CCRT and radical surgery at our institution were reviewed. All patients received CCRT using the intensity-modulated radiation therapy with 48 Gy to gross tumor and 43.2 Gy to regional lymphatic basin in 24 fractions. Side effects, clinical tumor responses, pathological responses, and surgical margin status were analyzed. Pathological T down-staging was noted in seven patients (46.7%); pathological complete response was achieved in three patients (20%). Fourteen patients (93.3%) had larynx preservation; eight patients (53.3%) achieved negative surgical margins. The 2-year overall survival, local relapse-free survival, and regional relapse-free survival were 50.6%, 62.2%, and 47.5%, respectively. Neoadjuvant CCRT and larynx-sparing surgery are feasible and tolerable in patients with cervical esophageal SCC. Prospectively designed studies for large patient groups and long-term follow-up results are needed for validating this multimodality therapy.

Effectiveness of auricular orthosis in the treatment of children with congenital auricular deformity / 中华整形外科杂志

Objective@#To explore the treatment effects of domestic auricular orthosis on children born with congenital auricular deformity.@*Methods@#Children born with congenital auricle deformity were treated by "Yi Er" auricle orthosis, included 42 ears of 29 cases.These children were divided into three groups according to the birth age. The age less than 7 days was divided into group 1, 7-42 days for group 2, and more than 42 days for group 3. Compare the therapeutic effect of children in different ages.@*Results@#The therapeutic effect was divided into three grades: markedly effective and cured (basically return to normal appearance); effective (improved, but not reached the normal appearance); invalid (no improvement after treatment). The markedly effective and cured rate in group 1, group 2 and group 3 were 100%, 85.7% and 45.0%, the difference was statistically significant(P<0.05), and the average correction time was(20.75±6.50)d, (32.64±15.40)d, (48.23±17.32) d, the difference was statistically significant(P<0.05).@*Conclusions@#The domestic auricle orthosis has a significant effect on the correction of children born with congenital auricular deformity. The better treatment effect and the shorter wearing time can be acquired in the early correction.
