Prognostic impact of baseline tumour immune infiltrate on disease-free survival in patients with completely resected, BRAF v600 mutation-positive melanoma receiving adjuvant vemurafenib. Ann Oncol 2021; 31:153-159. [PMID: 31912791 DOI: 10.1016/j.annonc.2019.10.002] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2019] [Revised: 09/11/2019] [Accepted: 10/03/2019] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND We conducted a retrospective exploratory analysis to evaluate the effects of baseline tumour immune infiltrate on disease-free survival (DFS) outcomes in patients with fully resected stage IIC-IIIC melanoma receiving adjuvant vemurafenib monotherapy or placebo in the BRIM8 study. PATIENTS AND METHODS BRIM8 was a phase III, international, double-blind, randomised, placebo-controlled study. Eligible patients with BRAFV600 mutation-positive, completely resected melanoma were randomly assigned to oral vemurafenib (960 mg twice daily) or matching placebo for 52 weeks. The primary end point was DFS. The association of CD8+ T-cell infiltration and programmed death ligand 1 (PD-L1) expression with DFS, as measured by immunohistochemistry, was explored retrospectively. RESULTS Four hundred ninety-eight patients were randomly assigned to receive adjuvant vemurafenib (n = 250) or placebo (n = 248); tumour samples were available for biomarker analysis for approximately 60% of patients. In the pooled biomarker population, placebo-treated patients with <1% CD8+ T cells in the tumour centre had shorter median DFS than those with ≥1% CD8+ T cells (7.7 versus 47.8 months). DFS benefit from vemurafenib versus placebo was greater in patients with <1% CD8+ T cells [hazard ratio (HR) 0.56; 95% confidence interval (CI) 0.34-0.92) than in patients with ≥1% CD8+ T cells (HR 0.77; 95% CI 0.48-1.22). Likewise, median DFS was shorter among placebo-treated patients with <5% versus ≥5% PD-L1+ immune cells (IC) in the tumour (7.2 versus 47.8 months). A greater DFS benefit with vemurafenib versus placebo was observed in patients with <5% PD-L1+IC (HR 0.36; 95% CI 0.24-0.56) than in patients with ≥5% PD-L1+IC (HR 0.99; 95% CI 0.58-1.69). CONCLUSIONS The presence of CD8+ T cells and PD-L1+IC are favourable prognostic factors for DFS. Treatment with adjuvant vemurafenib may overcome the poor DFS prognosis associated with low CD8+ T-cell count or PD-L1 expression. CLINICALTRIALS. GOV IDENTIFIER NCT01667419.

Evidence of TWIST1 and transforming growth factor-B1 aberrant expressions as novel therapeutic targets in modulating the severity of osteoarthritis with focus on biologic agents. JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY : AN OFFICIAL JOURNAL OF THE POLISH PHYSIOLOGICAL SOCIETY 2020; 71. [PMID: 33727429 DOI: 10.26402/jpp.2020.6.06] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Accepted: 12/30/2020] [Indexed: 11/03/2022]
Abstract
Osteoarthritis (OA) is marked by transcriptional factors. Twist-related protein 1 (TWIST-1) leads to the down-regulation of functional transcriptional regulators such as transforming growth factor-beta 1 (TGF-β1) and Wnt signals, thus blocking the growth and maturation of chondrocytes and providing new pathways to the production of therapeutic targets in OA therapy. Our research assesses the role of aberrant expressions TWIST1 and TGF-β1 as therapeutic targets in the regulation of osteoarthritis by treating with piperlongumine, a known biological agent. Monosodium iodoacetate (MIA) was administered to 32 male Wistar rats into their knee joints to provoke osteoarthritis. A week later, piperlongumine (PL) was orally administered to these rats for a duration of 28 days. The radiographic photos of these rats were documented. The histopathological and serum factors, namely interleukin-1beta (IL-1β), matrix metaloproteinases MMP-1 and MMP-3, were evaluated and their respective results were reported. RNA was extracted and real-time-PCR technique was optimized for TWIST1, TGF-1β and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) determination and sample values were recorded. When treated with PL at 100 mg/kg, our radiographic and histological studies revealed a substantial reduction of OA in rat models but no major improvements were observed at PL 50 mg/kg. Serum levels of IL-1β, MMP-1, and MMP-3 were greatly decreased when treated with PL 100 mg/kg. When administered with a dose higher than PL-100 mg/kg, the relative expressions of TWIST1, mRNA and TGF-β1 mRNA proteins were drastically reduced. Our results suggested that high-dose treatment with piperlongumine was beneficial and effective. TWIST1 and TGF-β1 aberrant expressions contributed as a new transcription factor function and supported the reduction of osteoarthritis intensity with piperlongumine therapy.

Abstract
Osteoporosis is a chronic disease of low bone mass and fragility. Treatment is frequently compromised by suboptimal medication compliance causing increased morbidity. This review investigates adherence and persistence to parenteral osteoporosis therapies. Findings reveal parenteral medications requiring reduced dosing frequency have higher compliance than oral therapies. This systematic review examines real-world adherence to parenteral osteoporosis therapies. We searched PubMed, Medline, and EMBASE databases for English language observational studies that examined patient adherence and/or persistence to parenteral osteoporosis treatments (teriparatide sc, ibandronate iv, zoledronic acid iv, and denosumab sc) in adults with osteoporosis published up to September 2018. Studies with only self-reported adherence or persistence data and those with less than 20 patients were excluded. Quality assessment of included studies was completed using the Newcastle-Ottawa quality assessment scale (NOS). We identified 40 eligible studies. Teriparatide was examined in 29 studies, with persistence rates of 10-87% (median 55%) at 1 year and 10-69% (median 29.5%) at 2 years, and adherence rates of 21-89% (median 53%) at 1 year and 37-68% (median 40%) at 2 years. Ten studies of zoledronic acid reported persistence rates of 34-73% (median 42%) for second dose and 20-54% (median 35.8%) for third dose. Ten studies of ibandronate adherence reported and 2-year persistence rates of 31-58% (median 47.5%) in 1 year and 13-35% (median 25%) at 2 years, and adherence rates of 21-72% (median 47.3%) and 15-58% (median 36.5%) respectively. Denosumab was reported in 19 studies, with second (1 year) and fourth (2 year) dose persistence rates of 61-100% (median 81%) and 36-99% (median 45.5%). There is substantial heterogeneity in reports of persistence and adherence rates with parenteral osteoporosis therapies. Most of the published data are from short-term studies and evaluations of long-term adherence and persistence with parenteral therapies for osteoporosis are needed.

Abstract
OBJECTIVE To determine the respective weights of certain facial signs on the assessment of perceived age, tired-look and healthy glow on Chinese men of different ages. MATERIAL AND METHODS Photographs were taken of the faces of 420 Chinese men of different ages, under standardized conditions. These photographs allowed to focus and define 15 facial signs, which were then graded by 15 experts and dermatologists, using standardized scales provided by a reference Skin Aging Atlas. The facial signs were dispatched into 5 clusters, namely wrinkles/texture, ptosis/sagging, pigmentation disorders, vascular disorders and cheek skin pores. A naïve panel, composed of 80 Chinese women, of similar age range were asked, when viewing full-face photographs, to: (i) attribute on a 0-10 scale their perception of both the tired-look and healthy glow aspects and (ii) estimate the age of the subject. RESULTS With the exception of vascular disorders, the severity of all 4 clusters increased with age, although at different rates. The ptosis/sagging or pigmentation disorders showed a rather regular progression. Although perceived ages and real ages were found to be closely correlated, the vast majority of subjects were judged older by 2-10 years. The changes in facial signs (and their related clusters) were significantly correlated with perceived age, with the exceptions of skin spot density and cheek skin pores. Although the aspects of tired-look and healthy glow were logically found to be anti-correlated, tired-look was more statistically associated with perceived age for the five clusters. Signs of eye contour appear to be closely correlated with the perception of a tired-look. CONCLUSION Within facial clinical clusters, wrinkles/texture and ptosis/sagging are major factors in the assessment of perceived age in Chinese men. Tired-look appears to be strongly associated with perceived age.

Abstract
Objective: To investigate the effect of intestinal preparation on the efficacy and complications of fecal microbiota transplantation (FMT). Methods: A retrospective cohort study was performed. Clinical and follow-up data of 1501 patients who received FMT in the department of Colorectal Disease Specialty, Intestinal Microecology Diagnosis and Treatment Center, the Tenth People's Hospital, Tongji University from February 2018 to June 2019 were collected retrospectively. According to the intestinal preparation before FMT treatment, patients were divided into non-intestinal preparation group (n=216), antibiotic pretreatment group (n=383), intestinal cleansing group (n=267), and antibiotic combined with intestinal cleansing group (n=635). The adverse reactions after FMT treatment and the effective rates at 4-week and 8-week after treatment among the groups were compared. Patients, who repeated FMT treatment in the 3rd month and the 6th month due to reduced efficacy or ineffectiveness were divided into two subgroups: without intestinal preparation group and with intestinal preparation group. The effective rates of the two subgroups were compared. Results: Of the 1501 cases, 588 were male and 913 were female with mean age of (43.3±13.7) years and body mass index of (20.2±2.1) kg/m(2). Transplantation course was (3.3±1.7) weeks. The underlying diseases mainly included constipation (n=564), Crohn's disease (n=157), ulcerative colitis (n=142), irritable bowel syndrome (n=158), recurrent C. difficile infection (CDI) (n=106), autism (n=84), radiation intestinal injury (n=133), radiation enteritis (n=133), and non-CDI chronic diarrhea (n=60); the remaining cases (n=155). Baseline data among the 4 groups were not significantly different (all P>0.05). The overall morbidity of complication was 31.1% (467/1501), including 41 cases of vomiting (2.7%), 91 of nausea (6.1%), 49 of diarrhea (3.3%), 41 of abdominal pain (2.7%), 79 of bloating (5.3%), 72 of throat pain (4.8%), 38 of dizziness (2.5%), 51 of fever (3.4%), 3 of pulmonary infection (0.2%) and 2 of intestinal infection (0.1%). The above symptoms disappeared after symptomatic treatment. There was no statistically significant difference in the incidence of adverse reactions among the 4 groups (P>0.05). After 4-week of FMT treatment, the overall effective rate was 63.5% (902/1420); the effective rate of non-intestinal preparation group, antibiotic pretreatment group, intestinal cleaning group, and antibiotic combined with intestinal cleansing groupwas 57.6% (114/198), 64.2% (231/360), 60.2% (154/265) and 66.5% (403/606), respectively, with no statistically significant difference (χ(2)=6.659, P=0.084). After 8-week of FMT treatment, the overall effective rate was 61.3% (729/1293); the effective rate of non-intestinal preparation group, antibiotic pretreatment group, intestinal cleaning group, and antibiotic combined with intestinal cleansing group was 54.0% (88/163), 62.2% (202/325), 57.4% (132/230) and 64.4% (370/575), respectively, with no statistically significant difference (χ(2)=13.620, P=0.003). The effective rates of antibiotic combined with intestinal cleansing group and antibiotic pretreatment group were obviously higher than that of non-intestinal preparation group (χ(2)=5.789, P=0.016; χ(2)=10.117, P=0.001). Subgroup analysis showed that in the third month, the effective rate at 4-week after treatment was 60.1% (184/306) in the without intestinal preparation group and 61.5% (115/187) in the with intestinal preparation group, whose difference was not significant (χ(2)=0.091, P=0.763); however, in the sixth month, the effective rate at 4-week after treatment was 51.4% (89/173) in the without intestinal preparation group and 61.2% (161/263) in the with intestinal preparationgroup, whose difference was significant (χ(2)=4.229, P=0.040). Conclusions: FMT treatment is safe and effective. The combination of antibiotics and intestinal cleaning can improve overall efficacy of FMT. For patients who need repeated FMT treatment, the combination of antibiotics and intestinal cleaning program within 3 months has no significant effect on the effective rate, but in the sixth month, combinedpreparation is necessary.

Abstract
Objective: To examine the association between the clinical efficacy of fecal microbiota transplantation (FMT) in recipients and the choice of donor, and to observe the characteristics of intestinal flora and metabolites among different donors. Methods: A retrospective case-control study was conducted. Donor whose feces was administrated for more than 30 recipients was enrolled. Data of 20 FMT donors and corresponding recipients at Intestinal Microecology Diagnosis and Treatment Center of the Tenth People's Hospital from October 2018 to December 2019 were collected retrospectively. During follow-up, the efficacy of each recipient 8-week after FMT treatment was recorded and analyzed. Based on the efficacy of each donor, the donors were divided into three groups: high efficacy group (effective rate >60%, 10 donors), moderate efficacy group (effective rate 30%-60%, 6 donors) and low efficacy group (effective rate <30%, 4 donors). The structure of the bacterial flora and the content of fecal short-chain fatty acids in each group of donors were detected and compared among groups. Association of the efficacy of each donor group with the morbidity of complications, and association of efficacy of recipients with donors were analyzed. The evaluation indicators of FMT efficacy included objective clinical effectiveness and/or subjective effectiveness. Objective effectiveness indicated clinical cure plus clinical improvement, and subjective effectiveness indicated marked effectiveness plus medium effectiveness through questionnaire during follow-up. Results: A total of 1387 recipients were treated by 20 donors, including 749 cases of chronic constipation, 141 cases of chronic diarrhea, 107 cases of inflammatory bowel disease (IBD), 121 cases of irritable bowel syndrome (IBS), 83 cases of autism, and 186 cases of other diseases, such as radiation bowel injury, intestinal pseudo-obstruction, paralytic intestinal obstruction, functional bloating and allergic diseases. There were 829 cases, 403 cases, and 155 cases in high efficacy group, moderate efficacy group and low efficacy group respectively. Baseline data among 3 groups were not significantly different (all P> 0.05). In comparison of bacterial abundance (operational taxonomic unit, OTU) among different effective donor groups, the high efficacy group was the highest (330.68±57.28), the moderate efficacy group was the second (237.79±41.89), and the low efficacy group was the lowest (160.60±49.61), whose difference was statistically significant (F=16.910, P<0.001). In comparison of bacterial diversity (Shannon index), the high efficacy group and the moderate efficacy group were higher (2.96±0.36 and 2.67±0.54, respectively), and the low efficacy group was lower (2.09±0.55), whose difference was statistically significant (F=5.255, P=0.017). In comparison of butyric acid content among three groups, the high efficacy group had the highest [(59.20±9.00) μmol/g], followed by middle efficacy group [(46.92±9.48) μmol/g], and the low efficacy group had the lowest [(37.23±5.03) μmol/g], whose difference was statistically significant (F=10.383, P=0.001). The differences of acetic acid and propionic acid among three groups were not statistically significant (all P>0.05). A total of 418 cases developed complications (30.1%). Morbidity of complication in low efficacy group, moderate efficacy group and high efficacy group was 40.6% (63/155), 30.0% (121/403) and 28.2% (243/829) respectively, and the difference was statistically significant (χ(2)=9.568, P=0.008). The incidence of diarrhea in low efficacy group, moderate efficacy group and high efficacy group was 7.1% (11/155), 4.0% (16/403) and 2.8% (23/829) respectively, and the difference was statistically significant (χ(2)=7.239, P=0.027). Comparing the incidences of other types of complications, no statistically significant differences were found (all P>0.05). Follow up began 8 weeks after the FMT treatment. The total follow-up rate was 83.6% (1160/1387). The overall effective rate 58.3% (676/1160). Effective rates of various diseases were as follows: chronic constipation 54.3% (328/604), chronic diarrhea 88.5% (115/130), IBD 56.1% (55/98), IBS 55.1% (59/107), autism 61.6% (45/73), and other diseases 50.0% (74/148). Comparing the effective rate of three groups of donors for different diseases, there was no statistically significant difference in chronic diarrhea (P>0.05); there was a positive correlation trend in IBD, IBS and autism, but the differences were not statistically significant (all P>0.05). For chronic constipation and other diseases, high efficacy group had the highest effective rate [65.0% (243/374) and 63.2% (55/87)], followed by moderate efficacy group [49.4% (86/174) and 38.1% (16/42)], and low efficacy group had the lowest [16.1% (9/56) and 15.8% (3/19)], whose differences were significant (all P<0.05). Conclusions: Different donors have different efficacy in different diseases. Chronic constipation, radiation bowel injury, etc. need to choose donors with high efficacy. IBD, IBS and autism may also be related to the effectiveness of donors, while chronic diarrhea is not associated to the donor. The efficiency of the donor is negatively correlated to the morbidity of complications. The abundance and diversity of intestinal flora and the content of butyric acid may affect the efficacy of the donor.

Abstract
Colorectal surgery patients have severe intestinal flora disorders and antibiotic resistant bacteria due to the disease itself and preoperative treatment, as well as the influence of dietary structure and environmental factors. Perioperative anesthesia and operative stress can cause gastrointestinal motility disorders. In addition, the widespread use of prophylactic broad-spectrum antibiotics and antiacids aggravate intestinal flora disorders and induces severe postoperative infectious diarrhea, such as pseudomembranous enteritis and fatal enteritis. The clinical manifectation are severe infectious diarrhea with high fever and abdominal distension after surgery. The disease progresses rapidly. When the diagnosis and treatment are delayed, the patient can quickly develop shock and other serious complications such as anastomotic leakage, even die of multiple organ failure. Therefore, early diagnosis and treatment are crucial.

Abstract
OBJECTIVE To explore some morphological features of the eyebrows of women of different ethnicities and ages. MATERIALS AND METHODS Standard digital photographs of 3600 women of six ethnicities, aged 18-84 years, previously used to describe the morphology of the human eyes, allowed us to focus on their eyebrows, as supplementary and opportunistic study. Photographs of both eyebrows were analysed partly by manual markings and automatically by dedicated algorithms. Six parameters of the eyebrows were recorded: length, waviness/curvature, oblique aspect, size (vertical height), total surface and hair coverage (density). RESULTS Most criteria present ethnic specificities. These are: length (longer eyebrows of Indian, shorter among African women); waviness where the straighter eyebrows were found among Chinese and Japanese women. In general, the longer the eyebrows, the higher their waviness and vice versa. Thickness (or height) of the eyebrows presents a wide ethnic variability as well as hair coverage, where African women present the lower hair density, inversely to Indian women. The same holds true with regard to the total surface of eyebrows, of a large variability (by about four times). Some criteria appear more individually dependent than ethnic-specific, such as the oblique positioning, at the exception of Indian women with less oblique eyebrows. In all subjects, the criteria of both eyebrows (Left vs. Right) were found to be highly correlated (r > 0.7, P < 0.001). CONCLUSION The present investigation brings new findings on a scarcely studied facial element, the morphologic features of which are, for most, ethnic-dependent. As applied consequences, the results of the present work pave the road to better adapt adorning procedures of the eyebrows vis-à-vis ethnic and age specificities.

Abstract
OBJECTIVE To assess the impact of an aerial chronic urban pollution (UP) on the severities of some facial signs of Chinese men living in two close but differently polluted Chinese cities. MATERIALS AND METHODS Standardized digital photographs were taken on 201 subjects from two cohorts of Chinese men (100 inhabitants of Baoding/very polluted and 101 inhabitants of Dalian/less polluted) differently aged (20-60 years) allowing a focus on 17 different facial signs. The latter were graded by 15 experts, using a clinical referential skin atlas. A questionnaire was filled by all subjects collecting their habits and uses with regard sun-exposures and skincare products. A naïve panel of 80 Chinese women, of comparable ages, attributed a perceived age to each subject under blind conditions. RESULTS These confirm previous data obtained on Chinese women, with a similar protocol, i.e. that some facial signs show an increased severity in the more polluted city. However, changes in facial signs, with age, are of a different pattern according to gender. In Chinese men, most signs show early onsets with however low age-related changes, inversely to those observed in women, at the exception of vascular disorders. Habits of sun-exposures and uses of skincare product were found totally similar in both cohorts, reinforcing the specific role of UP in the progressive changes of facial signs. Similar to the results previously obtained on Chinese women, men living in a more polluted city were judged older than those living in a less polluted aerial environment. CONCLUSION The present work confirms that a more severe UP increases the severities of some facial signs in Chinese men.

Abstract
In recent years, with the improvement of high-intensity focused ultrasound technology, ultrasound cycloplasty has once again gained clinical recognition, becoming one of the non-invasive procedures for glaucoma treatment. Although high-level evidence is still lacking so far, the existing literature has shown that ultrasound cycloplasty can effectively and safely decreases the intraocular pressure in glaucoma by reducing the formation of aqueous humor and increasing the drainage of aqueous humor through the uveoscleral pathway. This article focuses on the efficacy and safety of ultrasound cycloplasty in the treatment of glaucoma, reviews the existing literature, and summarizes the information on the development of equipment, treatment mechanisms, surgical procedures, effectiveness of intraocular pressure reduction, and post-operative complications, with the purpose to provide reference for clinical research and application.

Abstract
OBJECTIVES Swallowing disorder is a health burden for the elderly in China. This study aimed to investigate the prevalence of dysphagia and to test the association between skeletal muscle strength and swallowing problems among community-dwelling older adults. DESIGN A cross-sectional study. SETTING Community-dwelling Chinese elderly in China. PARTICIPANTS 3361 adults aged 65 years or above were involved, among which 1740 (51.8%) were female, with average age of 72.64 (Standard deviation, SD=6.10) years old. MEASUREMENTS Handgrip strength (HGS) was used to evaluate skeletal muscle strength. Dysphagia assessment was performed using the Eating Assessment Tool-10 (EAT-10) and the 30mL water swallow test (WST). Binary logistic regression was used to evaluate the relationship between skeletal muscle strength and dysphagia, and covariates as age, gender, material status, etc. were adjusted. RESULTS The prevalence of dysphagia were 5.5% and 12.9%, screened by EAT-10 and 30mL WST respectively. Participants with dysphagia showed lower HGS (21.73 ± 9.20 vs. 25.66 ± 11.32, p<0.001, by EAT-10; 20.26 ± 9.88 vs. 26.22 ± 11.28, p<0.001, by WST). The adjusted model suggested that muscle strength is a protective factor for swallowing disorders (adjusted OR=0.974, 95%CI: 0.950-0.999, by EAT-10; adjusted OR=0.952, 95%CI: 0.933-0.972, by WST). Subgroup analyses of WST found the effects were significant among participants aged in 70-74 years group and ≥75 years group, rather than those aged under 70. CONCLUSION Dysphagia was significantly associated with skeletal muscle strength among the community-dwelling elderly population. Effective interventions should be taken to manage the decline of muscle strength for the older adults, especially early prevention before 70 years old.

Abstract
Recently, many studies have been carried out to solve the particulate matter pollution problem. However, the detection accuracy for particulate matter in the atmosphere remains unsatisfactory due to the influence of the air relative humidity. Herein, we report a Ag nanowire film air heater to enhance the detection accuracy through internal heating. From air temperature and air relative humidity relationship analysis, it has been found that the Ag nanowire film air heater can form the most suitable air relative humidity in the detection system, thereby enhancing the detection accuracy. Consequently, the Ag nanowire film air heater-assisted light scattering particulate matter detector has achieved tremendous enhancement in its detection accuracy, which is comparable with the data obtained by the beta gauge method. Film resistance plays a key role in internal air temperature distribution and the resultant air relative humidity at given voltages. To achieve the most suitable air relative humidity for continuous online monitoring, response time and power consumption should be balanced. Therefore, guidance for designing Ag nanowire films with proper resistance used in an optional-sized detector has been given for quick response, high accuracy and low power consumption. This work is of significance for providing insight for future studies in particulate matter detection and pollution remediation.

Abstract
Neuroendocrine tumor(NET) is a kind of highly heterogeneous and ubiquitous tumor, frequently localized in the gastrointestinal tract and pancreas. Surgery combined with regional ablation, endocrine therapy,chemotherapy and targeted therapy presents a favorable prognosis when treated with G1 or G2 gastroenteropancreatic neuroendocrine tumor(GEP-NET). However, there are only limited therapeutic strategies for metastatic unresectable tumors and poorly differentiated NEC,which are closely related to the special tumor microenvironment of neuroendocrine tumors.Targeting tumor microenvironment therapy is an important method in current systematic therapy, but till now the knowledge of neuroendocrine tumor microenvironment and its related treatment are limited. This article will specifically introduce the characteristics of tumor microenvironment in GEP-NET from the following aspects: the formation of enrichment vascular supply in TME,the role of tumor stroma,immune cells and cancer associacted fibroblast, and immune checkpoint and future trend of immunotherapy.

Abstract
Interest has been growing in defects of halide perovskites in view of their intimate connection with key material optoelectronic properties. In perovskite quantum dots (PQDs), the influence of defects is even more apparent than in their bulk counterparts. By combining experiment and theory, we report herein a halide-vacancy-driven, ligand-directed self-assembly process of CsPbBr3 PQDs. With the assistance of oleic acid and didodecyldimethylammonium sulfide, surface-Br-vacancy-rich CsPbBr3 PQDs self-assemble into nanowires (NWs) that are 20-60 nm in width and several millimeters in length. The NWs exhibit a sharp photoluminescence profile (≈18 nm full-width at-half-maximum) that peaks at 525 nm. Our findings provide insight into the defect-correlated dynamics of PQDs and defect-assisted fabrication of perovskite materials and devices.

Abstract
The ability to convert between molecular spin states is of utmost importance in materials chemistry. Förster-type energy transfer is based on dipole-dipole interactions and can therefore theoretically be used to convert between molecular spin states. Here, a molecular dyad that is capable of transferring energy from an excited triplet state to an excited singlet state is presented. The rate of conversion between these states was shown to be 36 times faster than the rate of emission from the isolated triplet state. This dyad provides the first solid proof that Förster-type triplet-to-singlet energy transfer is possible, revealing a method to increase the rate of light extraction from excited triplet states.

Abstract
A total of 1 685 school-age children selected from Hangzhou received lung function testing to evaluate the short-term effects of air pollution on their lung function. The results showed that in every 10 μg/m(3) increase of average concentration of PM(2.5) and PM(10) on the day of the test and the day before the test,peak expiratory flow (PEF) decreased 0.039 (95%CI: 0.012-0.067) L/s and 0.031 (95% CI:0.011-0.051) L/s,respectively. When the average concentration of SO(2) increased 10 μg/m(3) on the day of test and the day prior to the test, PEF and 75% of the forced vital capacity that has not been exhaled (MEF(75)) decreased 0.437 (95%CI: 0.217-0.658) L/s and 0.396 (95%CI: 0.180-0.613) L/s. After being adjusted for NO(2),with every 10 μg/m(3) increase of average concentration of PM(2.5) and PM(10) on the day of the test and the day before the test,PEF and MEF(75) decreased 0.056 (95%CI: 0.028-0.085), 0.053(95%CI: 0.027-0.081) and 0.047 (95%CI: 0.026-0.068) L/s,0.044 (95%CI: 0.023-0.065) L/s on the day before the test, respectively. The results indicate that air pollution have short-term and lag effects on lung function of school-age children in Hangzhou.

Abstract
Objective: To evaluate the preliminary efficacy and safety of penetrating canaloplasty for treating primary angle-closure glaucoma (PACG). Methods: It is a prospective interventional case series study. Twenty-two patients (24 eyes) with PACG were treated with penetrating canaloplasty (video attached) at the Eye Hospital of Wenzhou Medical University from June 2015 to August 2018. This modified canaloplasty was performed by making a window at the corneal-scleral bed. Aqueous was redirected to the opening of Schlemm's canal after the canaloplasty with intension sutures. Postoperative follow-up was made at 1 day, 7 days, 1 month, 3 months, and 6 months. Surgical success was defined as intraocular pressure (IOP) ≤ 21 mmHg (1 mmHg=0.133 kPa) with glaucoma medication (quantified success) and without any glaucoma medication (complete success). Main outcome measures included IOP, number of medication, surgical success rate, complications, and filtering bleb status. One-way repeated measure ANOVA and rank sum test were used in statistical analysis. Results: Due to the failure of circumferential catheterization of the canal, 4 eyes converted to trabeculectomy. A total of 19 PACG patients (20 eyes) achieved the successful 360-degree catheterization of the canal, including 11 males and 8 females. The mean age was (54±7) years old (range: 41-65 years old), and the mean angle-closure range was (326.3±46.6) degrees. The mean preoperative IOP was (38.0±11.9) mmHg with the median medication number of 3 (range: 2-5). The mean postoperative IOP was (14.5±11.1), (16.1±6.0), (17.7±5.5), (15.7±5.0), and (15.4±3.7) mmHg at 1 day, 7 days, 1 month, 3 months, and 6 months, respectively. There was significant difference in IOP between postoperative and preoperative (all P<0.01). The median medication number (range) was 0 (0-3), 0 (0-2), 0(0-3), 0(0-2), and 0 (0-2) at the 5 time points, respectively. There was significant difference in medication number between postoperative and preoperative (all P<0.01). The quantified success rate was 95%(19/20), and the complete success rate was 90%(18/20) at 6 months. Postoperative complications were observed in 7 eyes (35%) of 20 PACG eyes, including 3 eyes (15%) with hyphema, 2 eyes (10%) with shallow anterior chamber, 1 eye (5%) with Descemet membrane detachment, and 1 eye (5%) with filtration obstruction at the trabeculum ostium. According to the results of slit lamp and ultrasound biomicroscopy examinations, 70% of the eyes (14/20) had no filtering bleb. Eight eyes (40%) with IOP spike were observed. Conclusion: Preliminary study shows penetrating canaloplasty is safe and effective in the treatment of PACG, but needs a longer follow-up. (Chin J Ophthalmol, 2019, 55: 448-453).

Abstract
Since the oxygen evolution catalysis process is vital yet arduous in energy conversion and storage devices, it is highly desirous but extremely challenging to engineer earth-abundant, noble-metal-free nanomaterials with superior electrocatalytic activity toward effective oxygen evolution reactions (OERs). Herein, we construct a prismlike cobalt-iron layered double hydroxide (Co-Fe LDH) with a Co/Fe ratio of 3:1 utilizing a facile self-templated strategy. Instead of carbon-species-coupled treatment, we focus on ameliorating the intrinsic properties of LDHs as OER electrocatalysts accompanied by the hierarchical nanoflake shell, well-defined interior cavity, and numerous microporous defects. In contrary to conventional LDHs synthesized via a one-pot method, Co-Fe LDHs fabricated in this work possess a huge specific surface area up to 294.1 m2 g-1, which not only provides abundant active sites but also expedites the kinetics of the OER process. The as-prepared Co-Fe LDH electrocatalysts exhibit advanced electrocatalytic performance and a dramatic stability of the OER in an alkaline environment. In particular, the contribution of micropore defects is clearly discussed according to the electrochemical impedance spectroscopy analysis, in which the time constant of the OER at the micropore defect is several orders of magnitude smaller than that at the exterior of Co-Fe LDHs, forcefully verifying the intrinsic catalytic activity enhancement derived from the micropore defects. This work provides a promising model to improve OER electrocatalyst activity via produce defects and research the contribution of micropore defects.
