[Giant trichilemmal carcinoma of the retroauricular: a case report]

The trichilemmal carcinoma is a rare tumor that usually occurs on sun-exposed skin, especially on the face, scalp, neck and back of hands, mainly in elderly subjects but commonly between the 4th and 9th decades of life. We report a case of giant trichilemmal carcinoma. A 65-year-old man presented with a 5-year history of a slowly developing mass arising from his right retroauricular region, with local destruction of the auricle. The lesion appeared as a 8.0 cm×6.5 cm×2.0 cm sized, with surface ulceration and erosion, subcutaneous nodule, and mild tenderness. Preoperative pathological biopsy showed: "retroauricular" trichilemmal carcinoma. The patient underwent right retroauricular tumor resection, partial auriculectomy, neck adjacent skin flap repair and auricle reconstruction. Postoperative pathological report: "retroauricular" trichilemmal carcinoma. The margin of incision was negative, and the lymph nodes in zone II were negative. Immunohistochemistry: Tumor cells were CK5/6（++）, p63（++）, p40（++）, CD10（-）, EMA（-）, Ki-67（+, about 60%）.

Safety, efficacy and tumor mutational burden as a biomarker of overall survival benefit in chemo-refractory gastric cancer treated with toripalimab, a PD-1 antibody in phase Ib/II clinical trial NCT02915432

BACKGROUND

High tumor mutational burden (TMB-H) is correlated with enhanced objective response rate (ORR) and progression-free survival (PFS) for certain cancers receiving immunotherapy. This study aimed to investigate the safety and efficacy of toripalimab, a humanized programmed death-1 (PD-1) antibody, in advanced gastric cancer (AGC), and the predictive survival benefit of TMB and PD-L1.

PATIENTS AND METHODS

We reported on the AGC cohort of phase Ib/II trial evaluating the safety and activity of toripalimab in patients with AGC, oesophageal squamous cell carcinoma, nasopharyngeal carcinoma and head and neck squamous cell carcinoma. In cohort 1, 58 chemo-refractory AGC patients received toripalimab (3 mg/kg d1, Q2W) as a monotherapy. In cohort 2, 18 chemotherapy-naive AGC patients received toripalimab (360 mg d1, Q3W) with oxaliplatin 130 mg/m2 qd, d1, capecitabine 1000 mg/m2 b.i.d., d1-d14, Q3W as first-line treatment. Primary end point was ORR. Biomarkers such as PD-L1 and TMB were evaluated for correlation with clinical efficacy.

RESULTS

In cohort 1, the ORR was 12.1% and the disease control rate (DCR) was 39.7%. Median PFS was 1.9 months and median OS was 4.8 months. The TMB-H group showed significant superior OS than the TMB-L group [14.6 versus 4.0 months, HR = 0.48 (96% CI 0.24-0.96), P = 0.038], while PD-L1 overexpression did not correlate with significant survival benefit. A 77.6% of patients experienced at least one treatment-related adverse event (TRAE), and 22.4% of patients experienced a grade 3 or higher TRAE. In cohort 2, the ORR was 66.7% and the DCR was 88.9%. A 94.4% of patients experienced at least one TRAE and 38.9% of patients experienced grade 3 or higher TRAEs.

CONCLUSIONS

Toripalimab has demonstrated a manageable safety profile and promising antitumor activity in AGC patients, especially in combination with XELOX. High TMB may be a predictive marker for OS of AGC patients receiving toripalimab as a single agent.

Formation of hierarchical porosity in oxidation of Ag films by reactive sputtering deposition of metal oxides via the Kirkendall effect

In this work, the conversion of Ag films to silver oxide nanorod arrays with hierarchical porosity which was realized in an oxidation environment by reactive sputtering deposition of metal oxides was reported. The mechanisms from the oxidation of Ag films to the formation of hierarchical porosity were investigated by varying the deposition parameters with the determination of phase structure, hierarchical porosity, diffusion coefficient, and chemical states of elements as well as by a comparison with the oxidation of Ag films by direct exposure to plasma. The oxidation of Ag films can be ascribed to the atomic oxygen in the environment. The formation of silver oxide nanorods and the creation of hierarchical porosity were substantiated to be due to the Kirkendall effect occurring between the oxidized Ag films and the deposited metal oxides with the assistance of the shading effect in deposition. In addition, the sample temperature and the attributes of metal oxides were found to have significant effects on the formation of hierarchically structured porous silver oxide films. The principle revealed in this work is of significance for the synthesis of porous materials with hierarchical porosity, especially for fabrication of hierarchically porous silver oxide films with improved properties, which are needed in the research fields of solid-state thin film batteries, photocatalysts, bactericides, gas sensors, etc.

[Clinical value of pegylated interferon-α plus ribavirin-based therapy in antiviral treatment of chronic hepatitis C in China]

Chronic hepatitis C virus (HCV) infection is one of the most common causes of liver cirrhosis and hepatocellular carcinoma in China. The older standard treatment regimen for chronic hepatitis C was the pegylated interferon-alfa plus ribavirin(PR). Now newer oral medications called direct antiviral agents (DAAs) has been gradually changed to PR-based DAAs and interferon-free, oral DAAs; making chronic hepatitis C a curable disease. This article intends to expound the advantages and disadvantages of PR-based therapy and provide reference for the treatment of chronic hepatitis C.

[Multicenter investigation of extracorporeal membrane oxygenation application in pediatric intensive care unit in China]

Objective: To survey the conduction and evaluate the effectiveness of extracorporeal membrane oxygenation (ECMO) therapy in pediatric intensive care unit (PICU) in China mainland. Methods: In a questionnaire-based survey, we retrospectively reviewed the application of ECMO in children's hospital and general hospital in China mainland to summarize and analyze the categories of diseases and prognosis of children treated with ECMO therapy. Results: By December 31, 2017, a total of 23 hospitals using ECMO, including 22 tertiary referral hospitals and 1 secondary hospital, among which 16 were children's hospitals and 7 were general hospitals. Thirty-seven ECMO equipment was available. A total of 518 patients treated with ECMO, within whom 323 (62.4%) successfully weaned from ECMO and 262 (50.6%) survived to discharge. Among 375 pediatric patients, 233 (62.1%) were successfully weaned from ECMO and 186 (49.6%) survived to discharge. Among 143 newborn patients, 90 (62.9%) successfully weaned from ECMO, 76 (53.1%) survived to discharge. ECMO was applied in veno-arterial (VA) mode to 501 (96.7%) patients, veno-venous (VV) mode to 14 (2.7%) patients, and VV-VA conversion mode to 3 (0.6%) patients. Sixty-nine patients required extracorporeal cardiopulmonary resuscitation (ECPR), including 20 newborn patients (29.0%) and 38 pediatric patients (71.0%), who were all with cardiovascular disease. Neonatal respiratory distress syndrome (26/61), persistent pulmonary hypertension of the newborn (PPHN) (12/61), and meconium aspiration syndrome (MAS) (11/61) are the most common pulmonary diseases in newborn patients; among whom, infants with PPHN had highest survival rate (10/12), followed by MAS (9/11). Among newborn patients with cardiovascular diseases, those who admitted were after surgery for congenital cardiac disease were the most common (54/82), while those with septic shock had the highest survival rate (2/3). In pediatric pulmonary diseases, acute respiratory distress syndrome was the most common (42/93), while plastic bronchitis was with the highest survival rate (4/4), followed by viral pneumonia (13/16). Among pediatric cardiovascular diseases, congenital cardiac defect was the most common (124/282), while fulminant myocarditis had the highest survival rate (54/77). Conclusion: The application of ECMO as a rescue therapy for children with severe cardiopulmonary failure has dramatically developed in China mainland.

[Clinical characteristics and analysis of patients with hematological diseases and HCV-Ab positive]

Objective: To observe the biological characteristics of patients with hematological diseases and hepatitis C antibodies positive and to investigate features of HCV infection and reactivation. Methods: A total of 85 patients with seropositive HCV at the hematology ward in Henan Cancer Hospital between October 2010 and October 2015 were analyzed. The clinical characteristics and laboratory data were retrospectively reviewed. Original disease treatment information was obtained from the medical records. Results: The positive rate of HCV-Ab was 1.2%, which was significantly higher than that of the general population(1.2% vs 0.4%, P<0.001). Of the 25 patients who showed anti-HCV seroconversion during the period of treatment or follow-up, serum ALT level was elevated in 15 patients(60.0%)and AST level got synchronous increase in 14 patients (56.0%). Of the 85 patients with positive HCV-Ab, 13 (15.3%) patients suffered from HCV reactivation with hepatic injury in varying degrees after chemotherapy or HSCT. Conclusions: Patients with hematological diseases have high incidence of HCV infection and reactivation, and most of them have hepatic injury. Chemotherapy and HSCT are important risk factors for HCV reactivation.

Percutaneous transforaminal endoscopic discectomy and miniincision surgery in the treatment of lumbar intervertebral disc protrusion

Lumbar intervertebral disc protrusion (LIDP) is a frequently occurring disease and 10-20% of patients require surgical treatment. Percutaneous transforaminal endoscopic discectomy (PTED) and mini-incision surgery are currently the most common surgeries for patients. To analyze the efficacy of PTED and mini-incision surgery in the treatment of lumbar intervertebral disc protrusion, this study selected 216 patients with LIDP who were admitted to the hospital between February 2014 and June 2015. The subjects were randomly divided into an observation group and a control group, 108 each. Patients in the observation groups were treated by PTED, while patients in the control group were treated by mini-incision surgery, and treatment efficacy of the two groups was observed. The results demonstrated that the duration of surgery and length of hospital stay of the observation group were significantly shorter than those of the control group, the intraoperative blood loss of the observation group was significantly less than that of the control group and the size of surgical incision of the observation group was much smaller than that of the control group (P less than 0.05). As to clinical efficacy, in accordance with the Japanese Orthopaedic Association (JOA) score and the Visual Analogue Scale (VAS) score, results of the observation group were superior to those of the control group at 3 months after surgery (P less than 0.05). In conclusion, treating patients with LIDP through PTED can significantly improve treatment efficacy, shorten surgical and healing time and relieve pain. This therapy is worth clinical promotion.

[Progress in diagnosis and management of syncope in children]

Syncope is a common emergency of children and adolescents, which has serious influence on the quality of life. Neurally-mediated syncope, including postural tachycardia syndrome, vasovagal syncope, orthostatic hypotension and orthostatic hypertension, is the main cause of syncope in children and adolescents. The main manifestations of neurally-mediated syncope are diverse, such as dizziness, headache, chest tightness, chest pain, pale complexion, fatigue, pre-syncope and syncope. Although the clinical manifestations are similar, each subtype of syncope has its hemodynamic feature and optimal treatment option. The diagnosis rate of syncope in children has been greatly improved on account of the development of the diagnostic procedures and methods. In recent years, with the promotion of head-up tilt test and drug-provocated head-up tilt test, the hemodynamic classification of neurally-mediated syncope gets continually refined. In recent years, with the effort of clinicians, an appropriate diagnostic protocol for children with syncope has been established. The initial evaluation consists of history taking, physical examination, standing test and standard electrocardiography. After the initial evaluation, some patients could be diagnosed definitely, such as postural tachycardia syndrome, orthostatic hypotension, and situational syncope. Those with a specific entity causing syncope need selective clinical and laboratory investigations. Patients for whom the cause of syncope remained undetermined should undergo head-up tilt test. The precise pathogenesis of neurally-mediated syncope is not entirely clear. In recent years, studies have shown that neurally-mediated syncope may be related to several factors, including hypovolemia, high catecholamine status, abnormal local vascular tension, decreased skeletal muscle pump activity and abnormal neurohumoral factors. Currently based on the possible pathogenesis, the individualized treatment of neurally-mediated syncope has also been studied in-depth. Generally, the management of neurally-mediated syncope includes non-pharmacological and pharmacological interventions. Patient education is the fundamental part above all. In addition to exercise training, the first-line treatments mainly include oral rehydration salts, beta adrenoreceptor blockers, and alpha adrenoreceptor agonists. By analyzing the patient's physiological indexes and biomarkers before treatment, the efficacy of medication could be well predicted. The individualized treatment will become the main direction in the future researches.

[Co-morbidity of vasovagal syncope and postural tachycardia syndrome with allergic diseases in children]

OBJECTIVE

To explore the clinical characteristics of the co-morbidity of vasovagal syncope (VVS) and postural tachycardia syndrome (POTS) with allergic diseases in children.

METHODS

A re-trospective analysis was launched to summarize the clinical data of children with VVS and POTS. They were divided into allergic group and non-allergic group according to the history of allergic diseases. The participants' clinical characteristics were compared between allergic group and non-allergic group using independent sample t test or rank sum test; composition comparisons were completed by Chi-square test. Bi-variate correlation analysis was used to explore the association between eosinophil percentage/count and symptom scores/frequency of syncope episodes. A P value <0.05 was defined as statistically significant.

RESULTS

Sixty-seven children complaining of orthostatic intolerance (43 patients diagnosed as VVS and 24 cases diagnosed as POTS) were enrolled. Totally 21 cases (31%) had allergic diseases, including allergic rhinitis, atopic eczema, asthma, as well as food allergy. And allergic rhinitis is the most common co-morbidity. There were no significant differences between the two groups in age, gender ratio, height, body weight and basement blood pressure. Compared with the non-allergic group, the allergic group showed later onset age (year) (11±2 vs. 9±3, P<0.05) of orthostatic intolerance and shorter course of the diseases (month) [8.0 (0.1, 0.1) vs. 24.0 (0.1, 144.0), P<0.05]. The frequency of syncope episodes in the allergic group among VVS children (times per month) [2.50 (0.08, 30.00) vs. 0.25 (0.03, 5.00), P<0.05] was much higher than that in the non-allergic group. Additionally, the eosinophil percentage (%) [3.50 (0.70, 0.59) vs. 1.65 (0.30, 6.20), P<0.001] and eosinophil count (×10⁹) [0.18 (0.05, 0.71) vs. 0.10 (0.02, 0.38), P<0.001] were increased in the allergic group. However, there were no remarkable differences in the results of head-up tilt test in children with VVS or in the maximum change of heart rate during standing test in children with POTS were involved.

CONCLUSION

Allergic diseases are common co-morbidities in children with both VVS and POTS. Allergic rhinitis is the most common co-morbidity. Children with co-morbidity of VVS/POTS and allergic diseases had a later onset of symptoms of orthostatic intolerance, and were more likely to be hospitalized for intensive attacks of symptoms during a short period when compared with those without allergic diseases. Children diagnosed as VVS combined with allergic diseases had more frequent episodes of syncope.

Fluoride-sulfophosphate glasses as hosts for broadband optical amplification through transition metal activators

Unusually stable multi-anion glasses of the fluoride-sulfophosphate type (FPS) are introduced as a new host material for optically active cation species. Despite a notoriously low polymerization grade, anion mixing in this glass system enables facile manufacture of bulk or fiber devices which combine several advantages of fluoride and phosphate glasses while using the stabilizing effect of sulfate additions. Using the example of chromium doping, we demonstrate broad red photoluminescence at 734 nm and inhomogeneous broadening of the R-line at 694 nm, originating from the ⁴T₂ → ⁴A₂ and ²E → ⁴A₂ transitions of Cr³⁺, respectively. The luminescence mechanism is further analyzed on the basis of the corresponding Tanabe-Sugano diagram. Tailored through chemical composition, internally nucleated precipitation of a nanocrystalline fluoride phase enables switching between high-field and low-field configurations of the Cr³⁺ ion, resulting in the specific emission properties and setting the path towards FPS-based optical devices.

[Sorafenib in combination with chemotherapy as first-line therapy for FLT3-ITD positive acute myeloid leukemia]

Objective: To analyze the clinical features of acute myeloid leukemia patients with Fms-like tyrosine kinase 3 internal tandem duplication (FLT3-ITD) mutation and the therapeutic effect of sorafenib in combination with chemotherapy as first-line therapy for these patients. Methods: Clinical features and therapeutic effect were retrospectively analyzed in 53 AML patients with FLT3-ITD mutation diagnosed in Henan Cancer Hospital from January 2013 to August 2016. The biological characteristics and clinical efficacy of chemotherapy in combination with or without Sorafeinb were analyzed. Results: FLT3-ITD mutation was identified in 53 AML patients, 22 cases (41.5%) were M(5) subtype. The median of the peripheral WBC was 61.00 (0.98-920.00) ×10(9)/L, and there were 50 (94.3%) patients with WBC>10×10(9)/L. The median of blast cell in bone marrow was 0.730 (0.234-0.966) . The total remission rate of all these 53 patients was 56.6% (30/53) . The complete remission (CR) rates in patients treated with chemotherapy in combination with sorafenib and patients with chemotherapy alone were 86.4% (19/22) and 35.5% (11/31) , respectively. The 1-year overall survival rates of the two groups were 78.3%% and 50.0% (P=0.041) , and 1-year progression free survival rates were 75.9% and 42.4% (P=0.044) , respectively. Conclusion: AML patients with FLT3-ITD mutation have the characteristics of high peripheral WBC, high blast cells in bone marrow and accompanying with M(5) subtype. Sorafeinb combined with chemotherapy can significantly improve CR rate and short term survival.

Efficacy and safety of fosaprepitant in the prevention of nausea and vomiting following highly emetogenic chemotherapy in Chinese people: A randomized, double-blind, phase III study

The prevention of chemotherapy‐induced nausea and vomiting was one of the most challenging supportive care issues in oncology, especially to highly emetogenic chemotherapy (HEC). A total of 645 patients were randomized into fosaprepitant group (fosaprepitant/placebo 150 mg d1 in combination with granisetron and dexamethasone) or aprepitant group (aprepitant/placebo 125 mg d1; 80 mg d2‐d3 plus granisetron and dexamethasone).The primary endpoint was the percentage of patients who had a complete response (CR) over the entire treatment course (0–120 hr, overall phase [OP]). It was assessed by using a non‐inferiority model, with a non‐inferiority margin of 10%. The difference of the CR rate was compared between two groups with chi‐square analysis. Six hundred and twenty‐six patients were included in the per protocol analysis. The percentage of patients with a CR in the fosaprepitant group was not inferior to that in the aprepitant group (90.85% versus 94.17%, p = .1302) during OP. Whether the cisplatin‐based chemotherapy or not, the CR rate of the fosaprepitant group was not inferior to that of the aprepitant group. Both regimens were well tolerated. The most common adverse event was constipation. Fosaprepitant provided effective and well‐tolerated control of nausea and vomiting associated with HEC in Chinese patients.

[Occupational stress and early health effects in migrant workers in an electronics manufacturing service enterprise]

Objective: To investigate occupational stress in migrant workers in an electronics manufacturing service enterprise and the association between occupational stress and early health effects, such as job burnout, depressive tendency, and insomnia. Methods: In August 2015, stratified random cluster sampling was used to select 1 097 migrant workers in an electronics manufacturing service enterprise. The Job Demand-Autonomy Questionnaire and effort-reward imbalance questionnaire were used to investigate occupational stress with the types of high workload and effort-reward imbalance, and Burnout Inventory, depression scale, and self-management sleep questionnaire were used to investigate the early health effects of occupational stress. Results: In these migrant workers, the detection rates of occupational stress with the types of high workload and effort-reward imbalance were 69.8%(766/1 097) and 11.9%(131/1 097). The multivariate logistic regression analysis showed that the workers who had occupational stress with the types of high workload and effort-reward imbalance had significantly higher risks of job burnout and depressive tendencies than those who did not have these two types of occupational stress (P<0.01). The workers who had occupational stress with the type of effort-reward imbalance had a significantly higher ability to predict the risks of job burnout and depressive tendencies than those who had occupational stress with the type of high workload (P<0.01) , as well as a significantly higher risk of insomnia than those who did not have this type of occupational stress (P<0.01). Conclusion: Occupational stress is the major influencing factor for early health effects, such as job burnout, depressive tendency, and insomnia, in the migrant workers in this electronics manufacturing service enterprise. The workers who have occupational stress with the type of effort-reward imbalance have higher risks of job burnout and depressive tendencies than those who have occupational stress with the type of high workload.

[Regulation of airway stem cell proliferation in idiopathic pulmonary fibrosis]

OBJECTIVE

To investigate the effect of fibroblasts on regulating airway stem cell proliferation in idiopathic pulmonary fibrosis.

METHODS

Lung cell suspension was prepared from β-actin-GFP mice. Airway stem cells were obtained by fluorescence activated cell sorting and co-cultured with lung fibroblasts. The fibroblasts were treated with TGF-β inhibitor SB43142. The expression of growth factors FGF1/2 and the effect of FGF1/2 on stem cell proliferation were observed.

RESULTS

The cloning efficiency of airway stem cells, when co-cultured with normal lung fibroblast cells for 8 days, was (3.5±1.1)%, while the cloning efficiency was reduced to (0.04±0.04)% when co-cultured with lung fibroblasts from idiopathic pulmonary fibrosis patients. The difference between the 2 groups was statistically significant(P=0.002 5). TGF-β receptor inhibitor SB431542 increased lung fibroblast growth factors FGF1/2 expression.FGF1 mRNA expression was increased to the experimental group 0.005 5 from 0.000 2 in the control group.FGF2 mRNA expression of the amount raised to the experimental group 0.000 15 from 0.000 8 in the control group.FGF1/2 promoted the growth of airway stem cells. After FGF1/2 was co-cultured with normal lung fibroblast cells for 8 days, the cloning efficiency of airway stem cells was (0.3±0.1)%.

CONCLUSION

During the development of idiopathic pulmonary fibrosis, fibroblast secreted FGF1/2 regulate airway stem cell proliferation.

Floquet edge states in germanene nanoribbons

We theoretically demonstrate versatile electronic properties of germanene monolayers under circularly, linearly, and elliptically polarized light. We show for the high frequency regime that the edge states can be controlled by tuning the amplitude of the light and by applying a static electric field. For circularly polarized light the band gap in one valley is reduced and in the other enhanced, enabling single valley edge states. For linearly polarized light spin-split states are found for both valleys, being connected by time reversal symmetry. The effects of elliptically polarized light are similar to those of circularly polarized light. The transport properties of zigzag nanoribbons in the presence of disorder confirm a nontrivial nature of the edge states under circularly and elliptically polarized light.

Relationship between cytokine gene polymorphisms and acute rejection following liver transplantation

Acute rejection (AR) recurrence after liver transplantation (LT) is one of the major complications that leads to chronic graft dysfunction. It has been reported that the polymorphisms in some cytokine genes are associated with human liver allograft rejection. This study mainly investigated the associations between polymorphisms in the genes encoding interleukin-10 (IL10), transforming growth factor-b1 (TGFB1), and tumor necrosis factor-a (TNF), and the risk of AR recurrence. We enrolled 359 LT recipients; they were divided into two groups: an AR group (N = 165) and a non-AR group (N = 194) according to whether they experienced rejection within the first month following liver transplantation. After providing informed consent, blood was collected and DNA was extracted. The single nucleotide polymorphisms of IL10 (-1082, -819, and -592), TGFB1 (+869 and +915), and TNF (-308) were investigated according to the methods used in previous studies. A significant difference was observed in the distribution of allelic frequencies at position +869 in TGFB1 between the AR and non-AR groups (P = 0.000). However, no significant differences (P > 0.05) were found in the genotype distributions in IL10, TNF, and TGFB1 between the AR and non-AR groups. Our study suggests that the +869 gene polymorphism of TGFB1 is significantly associated with liver graft rejection, while the other gene polymorphisms investigated in IL10, TNF, and TGFB1 are probably not risk factors for AR in LT recipients.

Relationship between the expression of Notch1 and EZH2 and the prognosis of breast invasive ductal carcinoma

We determined whether the coexpression of Notch1 and EZH2 influences the progression and prognosis of breast invasive ductal carcinoma. Using the χ(2) test, a significant difference was found between high and low expression of Notch1 in terms of lymph node, hormone receptor, and p53 expression (P < 0.05). Moreover, a significant difference was found between high and low expression of EZH2 in terms of tumor size, histologic grade, hormone receptor, and expression of Ki67 (P < 0.05). Using Pearson correlation analysis, we found a significant positive correlation between Notch1 and EZH2 expression in the tissue samples of breast invasive ductal carcinoma (P = 0.038). High Notch1 and EZH2 expression was associated with poor progression-free survival compared with low expression (PNotch1 = 0.000, 40.3 vs 48.9 months; PEZH2 = 0.000, 40.2 vs 49.9 months). Moreover, we found that high Notch1 and EZH2 expression was associated with poor overall survival compared with low expression (PNotch1 = 0.000, 51.2 vs 56.2 months; PEZH2 = 0.002, 51.7 vs 56.4 months). In conclusion, Notch1 and EZH2 coexpression contributes to the progression and prognosis of breast invasive ductal carcinoma.
