Abstract
To evaluate the effects of platelet-rich plasma (PRP) on promoting neural repair after facial nerve compression in rats and the mechanism by which this occurs. Methods: Adult Wistar rats (n=100) were divided into 3 groups: healthy controls, surgery-only, and surgery+PRP groups. The rats underwent nerve crush injury to establish a facial palsy model. The blood from the rats was used to prepare the PRP for application to the injury site. The evaluation methods included vibrissae movement, eyelid closure, and electrophysiology. Electron microscopy, immunohistochemistry, and real-time polymerase chain reaction (PCR) were used to detect nutrient factor expression in the brain and nerve sections. This study was conducted in Shandong Provincial ENT Hospital Affiliated to Shandong University, Shandong, China between January and November 2018. Results: Platelet-rich plasma promotes the recovery of vibrissae movement, eyelid closure, and electrophysiological function in a rat model of nerve crush injury. Hematoxylin and eosin staining, toluidine blue staining, and electron microscopy showed significant recovery of Schwann cells and axons in the PRP group. Polymerase chain reaction results showed that PRP releases growth factors, which include nerve growth factor and brain-derived neurotrophic factor. Immunohistochemistry also demonstrated higher levels of S-100 protein expression in the PRP group compared to the other groups. Conclusions: Platelet-rich plasma releases nutrient factors in the brainstem, and the use of PRP can promote injury recovery.

Abstract
INTRODUCTION Laryngeal adenoid cystic carcinoma (LACC) is an extremely rare malignant neoplasm. The etiology of LACC remains unknown, and it is characterized by multiple recurrences, slow progression, and late distant metastasis. This study aimed to provide more information regarding the characteristics, diagnosis, and treatment of LACC by analyzing 3 clinical cases and reviewing the literature on this topic. PATIENT CONCERNS Here, we present all 3 cases of LACC within the period between 2010 and 2019. Dyspnea was the most commonly observed symptom in these patients, followed by hoarseness, pharyngeal paresthesia, and difficulty swallowing. DIAGNOSIS All patients were pathologically confirmed as LACC. INTERVENTIONS All the patients underwent a combined therapy of surgical resection plus external irradiation. OUTCOMES The follow-up time was between 2 and 6 years; no local recurrence occurred in any of the 3 patients. Lung metastasis was found in 1 patient 6 years after surgery. CONCLUSION LACC is usually a slowly progressing cancer; the main treatment methods are surgery and radiotherapy, and the adequate radiotherapy dose should usually be greater than 60 Gy. The 5-year disease-specific survival rate is high; however, distant metastasis may still occur in patients with LACC even beyond 5 years after treatment. Therefore, patients with LACC require long-term surveillance.

[PMID: 31766993 PMCID: PMC6876087 DOI: 10.1186/s12883-019-1497-x] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2018] [Accepted: 10/14/2019] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Stroke-associated pneumonia (SAP) is a common complication of cerebrovascular disease. The A2DS2 score has been used to predict the risk of SAP. However, hyperglycemia is not included in this scale. The purpose of the present study was to explore whether the A2DS2 scoring system and hyperglycemia could predict the risk of SAP more effectively than the conventional A2DS2 scale. METHODS This retrospective study enrolled 2552 patients with acute ischemic stroke. The A2DS2 scores, fasting blood glucose level and blood glucose level on admission were collected. Regression analysis was used to identify the independent risk factors of SAP. ROC curve analysis was used to evaluate the specificity and sensitivity of the combined A2DS2 score and fasting hyperglycemia for predicting SAP. RESULTS Fasting hyperglycemia was an independent risk factor for SAP (OR = 2.95; 95% confidence interval: 2.11-4.12; P < 0.001). The area under curve of the combined A2DS2 score and fasting hyperglycemia was significantly higher than that of the A2DS2 score alone (0.814 vs. 0.793; P = 0.020). CONCLUSION Fasting hyperglycemia is an independent risk factor for predicting SAP. Compared with the A2DS2 score, the modified A2DS2 score (combined A2DS2 score and fasting hyperglycemia) is more effective in predicting the risk of SAP.

Diagnostic efficacy of serum anti-phospholipase A2 receptor antibodies for idiopathic membranous nephropathy in patients with diabetic kidney disease. Clin Chim Acta 2019; 502:222-226. [PMID: 31730818 DOI: 10.1016/j.cca.2019.11.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Revised: 10/18/2019] [Accepted: 11/04/2019] [Indexed: 01/19/2023] [Imported: 07/28/2023]
Abstract
AIM Serum anti-phospholipase A2 receptor (anti-PLA2R) antibodies are highly accurate in diagnosing idiopathic membranous nephropathy (IMN) in populations with kidney disease. However, the diagnostic value of anti-PLA2R antibodies for IMN in diabetic kidney disease (DKD) is unclear. The objective of this study is to determine the diagnostic efficacy and the optimal cut-off value of this marker in populations with DKD. METHODS This study included 227 patients with type 2 diabetes who were admitted to the Department of Nephrology of the Chinese People's Liberation Army General Hospital from May 2016 to January 2018 and underwent pathological diagnosis by renal biopsy. Anti-PLA2R antibodies were detected by enzyme-linked immunosorbent assay in this population. According to the pathological results, the participants were divided into an IMN group and non-membranous nephropathy (non-MN) group. The clinical characteristics were analyzed, the diagnostic ability of anti-PLA2R antibodies was evaluated, and the receiver operating characteristic (ROC) curve was constructed to obtain the optimal cut-off value. RESULTS There were 45 patients in the IMN group, accounting for 19.8% of the study sample. The patients in this group were older at the time of renal biopsy than the non-MN group and presented a shorter duration of diabetes, better glycemic control, lower blood pressure and uric acid, and better renal function; in addition, their clinical symptoms indicated nephrotic syndrome. The optimal cut-off value for anti-PLA2R antibodies for the diagnosis of IMN in DKD was 2.71 Ru/ml, sensitivity was 0.800, specificity was 0.951, positive predictive value was 0.800, negative predictive value was 0.951, accuracy was 0.921, and the Yoden index was 0.750. The area under the ROC curve was 0.87 (95% CI, 0.788-0.952) (p < 0.001). CONCLUSIONS Patients in the IMN group were older, had better renal function and general condition, and the clinical symptoms indicated nephrotic syndrome. Anti-PLA2R antibodies had a good diagnostic performance for IMN in the population with DKD, and the optimal cut-off value was 2.71.

Saccharomyces boulardii alleviates ulcerative colitis carcinogenesis in mice by reducing TNF-α and IL-6 levels and functions and by rebalancing intestinal microbiota. BMC Microbiol 2019; 19:246. [PMID: 31694526 PMCID: PMC6836350 DOI: 10.1186/s12866-019-1610-8] [Citation(s) in RCA: 116] [Impact Index Per Article: 23.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2018] [Accepted: 10/01/2019] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND AND AIMS To explore the inhibition mechanism of Saccharomyces boulardii (S. boulardii) on ulcerative colitis (UC) carcinogenesis. METHODS C57BL/6 mice were treated with azoxymethane and dextran sulfate sodium (AOM/DSS) to develop a UC carcinogenesis model. The treatment group was lavaged with S. boulardii (5 × 107 CFU/d) for 12 weeks. The mice were sacrificed and the tumor load in the treatment group was compared with that of a control group. The levels of TNF-α and IL-6 in colon tissue were measured by enzyme-linked immunosorbent assays. The influence of S. boulardii on TNF-α and IL-6 regulation was also investigated using different colon cell lines. Differences in intestinal microbiota in both stool and intestinal mucosa samples were assessed using 16S rDNA sequencing. RESULTS S. boulardii treatment reduced AOM/DSS-induced UC carcinogenesis in mice, as indicated by the reduced tumor load and reduced TNF-α and IL-6 levels in vivo, as well its effects on TNF-α and IL-6 activities in vitro. Significant changes in both fecal and mucosal microbiota were observed among the control, the AOM/DSS treated, and AOM/DSS plus S. boulardii treated groups. For fecal microbiota, the AOM/DSS treated group was lower in Lactobacillus, but higher in Oscillibacter and Lachnoclostridium than the control group. After intervention with S. boulardii, the percentage of Bacillus and Lactococcus increased, but Lachnoclostridium, Oscillibacter, Bacteroides, and Pseudomonas decreased. For the intestinal mucosal microbiota, the AOM/DSS treated group was lower in Bifidobacterium and Ruminococcaceae_UCG-014 and higher in Alloprevotella than the control group. After S. boulardii exposure, the percentage contributions of Lachnoclostridium and Lachnospiraceae_NK4A136 increased. CONCLUSIONS S. boulardii effectively reduced UC carcinogenesis in an AOM/DSS induced mice model. This positive result can likely be attributed to the reduction of TNF-α and IL-6 levels or the blockade of their function combined with alterations to the intestinal microbiota.

Abstract
Background: This retrospective study investigated whether baseline serum lipoprotein(a) (Lp(a)) may predict subsequent stroke in patients under chronic peritoneal dialysis (PD). Methods: Eight hundred and sixty incident PD patients, treated from 1 November 2005 to 28 February 2017, were enrolled, and followed until discontinuation of PD, death, or 31 May 2017. Hemorrhagic or ischemic stroke was the primary outcome. The population was stratified by baseline serum Lp(a) tertile. The risk of each stroke subtype was analyzed using the Cox proportional hazard models. Adjustments were made for: age; gender; history of stroke and hypertension; systolic blood pressure; lipid-lowering, antiplatelet and antihypertensive medications; laboratory profiles including hemoglobin, serum albumin, calcium, triglyceride, total and low-density lipoprotein cholesterol; and apolipoprotein A1. Results: Among the 860 participants, 19.3% and 4.1% had diabetes mellitus and a history of stroke, respectively. The median baseline serum Lp(a) was 328 (172-585) mg/L. After 28 (14-41) months of follow-up, 33 (3.84%) and 12 (1.40%) patients developed hemorrhagic and ischemic stroke, respectively. Participants in the highest Lp(a) tertile had a significantly lower risk of hemorrhagic stroke compared with those in the lowest tertile (hazard ratio (HR) 0.3, 95% confidence interval (CI) 0.1-0.86; p = .026); the rates of ischemic stroke were comparable among the tertiles. Each 10 mg/L rise in serum Lp(a) was associated with a 2% (95% CI 0.96-1; p = .033) lower risk of hemorrhagic stroke. Conclusions: Among patients with incident PD, a higher serum Lp(a) level may predict a lower risk of hemorrhagic stroke.

Abstract
BACKGROUND Endometriosis is a benign gynecological disorder which shares certain characteristics with malignant tumor like migration, invasion and proliferation. Glioma-associated oncogene homolog 1 (GLI1) has been implicated in some cancers including endometrial cancer, however, its role in endometriosis remains unknown. METHODS The aim of this study was to explore the expression pattern of GLI1 in endometriosis, and further investigate the effect of GLI1 regulation on human endometrial stromal cells. The expression of GLI1 in normal endometrium and ectopic tissues was analyzed by immunohistochemistry, quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and western blot. The Short hairpin RNA (ShRNA) intervention technique and GLI1 inhibitor GANT-61 were used to silence GLI1. The expression levels of GLI1, MMP2 and MMP9 was detected by qRT-PCR and western blot. The migration and invasion ability of human endometrial stromal cells was determined by wound healing assay and transwell migration/invasion assay. The viability and proliferation potentiality of cells was detected by MTT assays and colony formation assay, respectively. RESULTS We found that the expression of GLI1 mRNA and protein were significantly higher in ectopic endometrium from patients with endometriosis. Our analyses also show that GLI1 downregulation attenuated cells migration, invasion and proliferation abilities. What's more, reduced expression of GLI1 inhibited the expression of matrix metalloproteinase 2 (MMP2) and matrix metalloproteinase 9 (MMP9). CONCLUSIONS Our findings suggest that high levels of GLI1 may contribute to the development of endometriosis by promoting cell migration, invasion and proliferation involving regulation of MMP2 and MMP9 expression. Therefore, inhibition of GLI1 might be a novel potential therapeutic approach to the treatment of endometriosis, which sheds new light on our understanding of the pathogenesis of endometriosis.

Abstract
Small cell lung cancer metastasizing to the parotid gland is very rare and only a few cases have been reported. A 64-year-old man presented with a painless mass and peripheral facial paralysis. Neck ultrasound identified a solid mass in the right parotid gland with enlargement of the lymph nodes in the gland and the right submandibular lymph nodes. Lung computed tomography imaging demonstrated abnormalities in the upper and middle lobes of the right lung and intermediate bronchus, with obstructive pneumonia, as well as enlargement of the right hilar and mediastinal lymph nodes. Postoperative histopathological analysis identified small cell carcinoma in the right parotid gland with involvement of the right neck lymph nodes (one of eight). Bronchoscopy was performed and immunohistochemical analysis of the specimen demonstrated possible metastasis of small cell lung cancer to the parotid gland. From postoperative day 15, the patient started to undergo six cycles of an adjuvant chemotherapy regimen. No complications of the chemotherapy regimen were observed after three cycles. Treatment and follow-up are ongoing.

Abstract
OBJECTIVE To explore whether obesity patients with a body mass index (BMI) of ≥25 kg/m2 who suffer from stress urinary incontinence (SUI) or stress-predominant mixed urinary incontinence (S-MUI) show less improvement in urinary incontinence (UI) symptoms after electroacupuncture (EA) treatment compared with non-obese counterparts. METHODS This study was a secondary analysis of existing data. About 252 SUI patients and 250 S-MUI patients treated with the same EA regimen were assigned to one of the two groups: the obesity group for BMI ≥25 kg/m2 and the non-obesity group for BMI <25 kg/ m2 . The primary outcome was the proportion of treatment responders, defined as patients exhibiting a ≥50% reduction in 72-hours incontinence episode frequency, as measured by a 72-hours bladder diary at week 6 compared with baseline. RESULTS Of the 1004 randomised women, 129 obese women (86 SUI and 43 S-MUI) and 255 non-obese women (166 SUI and 89 S-MUI) treated with EA were included in a secondary analysis. The primary outcome was that 58.3% (74/127) of patients in the obesity group and 60.7% (150/247) of patients in the non-obesity group (difference 0.55%; 95% confidence interval, -10.01 to 11.11; P = .919) responded to treatment. CONCLUSION This study suggests that EA treatment may safely improve UI symptoms in both obese and non-obese patients, regardless of BMI category. Additionally, obesity status may not affect the efficacy of EA treatment on SUI or S-MUI among Chinese women.

Abstract
A subgroup analysis of the nationwide, cross-sectional 3B STUDY was performed to understand the current blood pressure (BP) control status and treatment patterns in Chinese diabetes patients as well as to identify factors associated with BP control. The demographic data, anthropometric parameters, and laboratory results were collected from 24 512 type 2 diabetes patients. The BP goal was a systolic BP <130 mm Hg and a diastolic BP <80 mm Hg regardless of a history of hypertension or current antihypertensive treatment. The overall prevalence of hypertension was 59.9% with geographical differences. Among the diabetes patients with hypertension, 76.9% received antihypertensive medicines. Calcium channel blockers (39.3%), angiotensin II receptor antagonists (26.6%), and then β-blockers (14.0%) or angiotensin-converting enzyme inhibitors (13.6%) were frequently used for BP control. Only 17.5% (n = 2658) of diabetes patients with hypertension reached the recommended target BP. Body mass index <24 kg/m2 , urban resident, frequent physical activity, good adherence to medication, comorbidity with cardiovascular disease, achieving glycemic goal (HbA1c <7.0%), achieving lipid goal (low-density lipoprotein cholesterol <2.59 mmol/L) were independent factors that predicted achievement of target BP goal. On the contrary, comorbidity with chronic kidney disease predicted failure to achieve target BP goal. Patients who were treated in a cardiology department or lived in the North were more likely to achieve BP goals. A considerable proportion of diabetic patients failed to achieve guideline-recommended BP targets. More aggressive efforts should be made to overcome the diverse barriers and facilitate the optimization of diabetes management.

Abstract
Background: To investigate the significant laboratory markers for early diagnosis of surgical site infection after spinal surgery. And determine the diagnostic cut-off values of these markers Methods: A total of 67 patients participated in the study: 11 patients who developed surgical site infection after spinal surgery (SSI Group) and 56 patients were compared with the infected group in terms of age,gender, operating time and intraoperative blood loss (Non-SSI Group). The white blood cell (WBC) count , WBC differential , C-reactive protein (CRP) and erythrocyte sedimentation rate(ESR) were determined before and 1, 3 and 7 days postoperatively . Then, we determine the diagnostic cutoff for these markers by using the receiver operating characteristic curve. Results: The CRP, ESR and WBC were significantly higher in the SSI group at 3 and 7 days postoperatively. The lymphocyte ratio at 3 days postoperatively was significantly lower in the SSI Group. Using the receiver operating characteristic curve,lymphocyte ratio <11.5% at 3 days postoperatively (sensitivity 90.9%, specificity 75.4%, area under the curve [AUC] 0.919), and C-reactive protein level >26 mg/dL at 7 days postoperatively (sensitivity 90.9%, specificity 87.7%, area under the curve [AUC] 0.954) were the significant laboratory marker for early detection of SSI Conclusion: Lymphocyte ratio<11.5% at 3 days and C-reactive protein levels>26.5mg/dl at 7 days after spinal surgery are reliable markers of SSI.

Abstract
BACKGROUND Single nucleotide polymorphisms (SNPs) of T-cell immunoglobulin- and mucin-domain-containing molecule 3 (TIM-3) were reported to individually associate with cancer risk. To further verify its correlation with human cancers, we evaluated the association of TIM-3 polymorphisms and the risk of cancer. METHODS Data were collected from electronic databases. Two reviewers independently selected studies, extracted data and assessed quality of the studies. Data were meta-analyzed using the STATA 13.0 software. Crude odd ratio (OR) and 95% confidence interval was used to estimate the association between TIM-3 polymorphism and cancer susceptibility. RESULTS All eligible case-control studies included a total of 4,852 participants (2,229 cases and 2,623 controls). The meta-analysis showed that TIM-3 SNPs (-1516G/T, -574G/T, +4259T/G, and haplotypes) were significantly associated with an increased risk of susceptibility toward all cancers. The subgroup analyses based on cancer types showed that TIM-3 -1516G/T SNP was only associated with an increased risk in developing cancers in the digestive system or in hospital-based populations. Moreover, the TIM-3 -574G/T SNP was associated with an increased cancer risk in the digestive system or other systems, while TIM-3 +4259T/G SNP was only associated with an increased cancer risk in hospital-based populations. Among the four haplotypes observed (GGT, TGT, GGG, and GTT), The GGG haplotype showed an increase in the odds of cancer by 2.614-fold (OR 2.614; 95% CI: 1.756-3.893) compared with the GGT haplotype. CONCLUSIONS TIM-3 SNPs (-1516G/T, -574G/T, +4259T/G and the four haplotypes) were associated with an increased risk of developing human cancers.

Abstract
Background Reconstruction of oral and maxillofacial defects requires soft and ductile flaps. Thoracodorsal artery perforator flap (TDAP) has good plasticity, but it is not widely used in the repair of oral and maxillofacial defects. The main aims of this study are to compare the skin elasticity and hardness of various free flaps commonly used in reconstructive surgery, and to explore the advantages and disadvantages of TDAP.Methods The elasticity and stiffness of the most commonly used free flaps in our department were measured by ElastiMeter and SkinFibroMeter. The elasticity and stiffness values of TDAP, anterolateral thigh flap, anterior medial femoral flap and forearm flap were measured respectively.Results The elasticity of TDAP was the lowest among all flaps, and the difference was statistically significant, except for the forearm flap (p = 0.000; p = 0.000; p = 0.06). The stiffness of TDAP was the lowest among all skin flaps, and the difference was statistically significant (p = 0.000; p = 0.000; p = 0.000).Conclusions TDAP is indeed suitable for reconstruction of head and neck defect, especially oral and oropharyngeal defect. Due to the ductile texture of TDAP, it is very conducive to the recovery of the morphology and function of oral and oropharyngeal organs.

Abstract
BACKGROUND Pulmonary sarcomatoid carcinoma (PSC) is a rare malignancy with both epithelial and sarcoma components, and high tumor metastasis potential. CASE PRESENTATION A 63-year-old male patient had a tumor in the right posterior mediastinum, and was eventually diagnosed with PSC and gingival metastasis. The patient underwent thoracoscopic right upper pneumonectomy with lymph node dissections, and the subsequent gingival biopsy revealed a metastatic PSC. The immunohistochemistry revealed that both PSC site tissues were positive for vimentin, CKAE1/AE3 and Ki-67. The patient received radiotherapy and chemotherapy after surgery, and deceased two months later due to systemic tumor metastases. CONCLUSION PSC metastasis is variable, and leads to diagnostic dilemma or erroneous diagnosis. A differential diagnosis can help to distinguish it from gingival cancer.

Abstract
RATIONALE Uterus-like masses (ULMs) are rare benign lesions that resemble the uterus. PATIENT CONCERNS Here, we describe the case of a woman with a ULM in the right broad ligament. A 51-year-old woman with a 2-month history of irregular vaginal bleeding was found to have a mass in the right broad ligament. Imaging studies revealed a solid-cystic lesion, suggestive of an endometrial cyst with malignant transformation. INTERVENTIONS She underwent prompt surgery for the removal of the mass. Intraoperatively, the uterus and ovaries appeared normal, and an 8-cm-long mass was observed in the right broad ligament without any connection to the uterus or ovaries. The mass was successfully excised. DIAGNOSES Postoperative histopathological examination showed that the cystic mass was filled with a blackish-brownish fluid and that it had thick walls resembling the uterine myometrium. The cyst center was lined by endometrial glands that were positive for cytokeratin as well as estrogen and progesterone receptors, and by stromal cells that were positive for CD10. OUTCOMES The patient recovered well and has had no further symptoms during 2 years of follow-up. LESSONS We have reported a case of ULM in the right broad ligament in a Chinese woman. Although ULMs are rare, they should be considered in the differential diagnosis for pelvic masses.

Abstract
Primary maxillofacial chordoma is extremely rare. We herein report a very rare case of a recurrent maxillofacial chordate tumor that was diagnosed in a 56-year-old woman who underwent three tumor resections. After surgical treatment, the patient healed well with an Eastern Cooperative Oncology Group score of 1. She was discharged to a local hospital for adjuvant radiotherapy. Close follow-up was ongoing at the time of this writing. Radical surgery and adjuvant radiotherapy remain the main treatment strategies for chordoma. Postoperative radiotherapy is particularly important. Our experience is to administer a total dose of 50 Gy to a clearly delineated target. If appropriate comprehensive treatment is available, distant metastasis of primary chordoma is rare, and neck dissection is therefore not generally recommended. Neck lymph node dissection is generally not recommended.

Abstract
The crumbs protein homolog 3 (CRB3) regulates the tight junction to help maintain epithelial polarity. Altered CRB3 expression was associated with carcinogenesis of epithelial cells. This study detected CRB3 expression in 192 cases of breast cancer tissues and in the Molecular Taxonomy of Breast Cancer International Consortium (Metabric) and The Cancer Genome Atlas (TCGA) datasets for association with triple negative breast cancer (TNBC) phenotypes. The in vitro experiments confirm the ex vivo data. The data showed that levels of both CRB3 mRNA and protein were associated with TNBC phenotypes, ie, 41.1% (39/95) of ER+ breast cancer was CRB3-positive, whereas 26.9% (25/93) ER- tumour was CRB3-positive (P = 0.046). Moreover, 47.6% (30/63) of PR+ breast cancer was CRB3-positive vs 28.4% (33/116) PR- tumours positive for CRB3 (P = 0.013). In addition, 40.1% (27/66) of ER+/PR+ tumour was CRB3-positive, but only 22.4% (19/85) of TNBC showed CRB3 expression (P = 0.048). Indeed, levels of CRB3 mRNA were higher in non-TNBC than TNBC in both Metabric (P = 3.682e-10) and TCGA datasets (P = 2.501e-07). The in vitro data showed that CRB3 expression was higher in luminal (MCF7 and T47D) than in HER2 (MDA-MB-453 and SK-BR-3) and basal (MDA-MB-231 and BT-549) breast cancer cell lines. More interestingly, ERα regulated expression of CRB3 protein in MCF7 and BT-549 cells and ERα expression was associated with CRB3 expression in breast cancer tissues specimens. This study demonstrated that ERα could be a novel regulator for CRB3 expression in breast cancer.

Abstract
OBJECTIVE To develop a gastric cancer (GC) risk prediction rule as an initial prescreening tool to identify individuals with a high risk prior to gastroscopy. DESIGN This was a nationwide multicentre cross-sectional study. Individuals aged 40-80 years who went to hospitals for a GC screening gastroscopy were recruited. Serum pepsinogen (PG) I, PG II, gastrin-17 (G-17) and anti-Helicobacter pylori IgG antibody concentrations were tested prior to endoscopy. Eligible participants (n=14 929) were randomly assigned into the derivation and validation cohorts, with a ratio of 2:1. Risk factors for GC were identified by univariate and multivariate analyses and an optimal prediction rule was then settled. RESULTS The novel GC risk prediction rule comprised seven variables (age, sex, PG I/II ratio, G-17 level, H. pylori infection, pickled food and fried food), with scores ranging from 0 to 25. The observed prevalence rates of GC in the derivation cohort at low-risk (≤11), medium-risk (12-16) or high-risk (17-25) group were 1.2%, 4.4% and 12.3%, respectively (p<0.001).When gastroscopy was used for individuals with medium risk and high risk, 70.8% of total GC cases and 70.3% of early GC cases were detected. While endoscopy requirements could be reduced by 66.7% according to the low-risk proportion. The prediction rule owns a good discrimination, with an area under curve of 0.76, or calibration (p<0.001). CONCLUSIONS The developed and validated prediction rule showed good performance on identifying individuals at a higher risk in a Chinese high-risk population. Future studies are needed to validate its efficacy in a larger population.

Abstract
OBJECTIVE Transarterial chemoembolization (TACE) is recommended to treat intermediate/advanced stage of hepatocellular carcinoma (HCC). However, the overall survival among initially TACE-treated patients varies significantly. The clinical characterization of long-term survival following TACE remains uncertain. We sought to identify clinical parameters and treatment requirements for long-term survival among patients with hepatitis B-related HCC who were initially treated with TACE. MATERIALS AND METHODS The included patients with HCC were admitted to our cancer center between December 2009 and May 2015. Patients who survived for >3 years were compared with those who died within 3 years. The clinical and laboratory findings that were associated with the survival were also analyzed. RESULTS One in six (17.9%) patients with HCC in this cohort survived for > 3 years after TACE. Body mass index (BMI) ≥ 23kg/m2 , aspartate aminotransferase levels ≤ 40 U/L, an activated partial thromboplastin time ≤ 34 seconds, α-fetoprotein (AFP) levels ≤ 25 ng/mL, antiviral therapy, tumor size ≤ 8 cm, solitary nodule, and the absence of vascular invasion were independently favorably associated with a 3-year survival. An absence of vascular invasion was the only independent factor associated with 3-year survival in patients who received resection and/or ablation after TACE. CONCLUSION In this cohort, a 3-year survival was associated with BMI, antivirus treatment, tumor status, hepatic function, and AFP level. Distant metastasis did not negatively impact the long-term survival among patients with hepatitis B-related HCC initially treated with TACE. Vascular invasion was the single impediment to long-term survival in patients who received add-on resection and/or ablation after TACE.

Analyzing the percentage of different PD-1 + T cell subsets in peripheral blood and bronchoalveolar lavage fluid of small cell lung cancer patients: A prospective study. Clin Exp Pharmacol Physiol 2019; 46:1074-1083.

Abstract
The present study was designed to evaluate the percentage of different programmed cell death-1 (PD-1)+ T cell subsets in peripheral blood and bronchoalveolar lavage fluid (BALF) of small cell lung cancer (SCLC) patients. The percentages of PD-1+ T cell subsets in peripheral blood and BALF samples obtained from 52 lung cancer and 20 pneumonia patients, and 20 healthy controls were examined by flow cytometry. In addition, clinical parameters, such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels, were also determined using Spearman's correlation test to assess their association with PD-1+ T cell subsets. These present results revealed that the percentage of circulating PD-1+ Tfh and peripheral helper T cells (Tph) cells significantly increased in peripheral blood of SCLC patients, when compared to non-small cell lung cancer (NSCLC) pneumonia patients and healthy controls. In addition, PD-1+ Tfh cells were also significantly enhanced in patients in the extensive-stage group. In contrast, the BALF samples of SCLC patients exhibited a significant decrease in percentage of Tph cells. An overall imbalance was observed between PD-1+ Tfh and Tph cells in both compartments. Furthermore, SCLC patients exhibited a significant decrease in the percentage of circulating PD-1+ Tfh and Tph cells following chemotherapy, and the in vitro analysis revealed that the concentration of IL-2 and IFN-γ derived from PD-1 + Tfh cells in SCLC were significantly lower than that from NSCLC. However, this had no significant correlation with disease severity. The present study indicated that elevated circulating PD-1+ T cells can primarily be used as a biomarker for disease diagnosis and a potential therapeutic target.
