AIM: To investigate the clinical efficacy of diquafosol sodium(DQS)eye drops combined with Qingrun Yangmu oral liquid in the treatment of dry eye after phacoemulsification and intraocular lens implantation.METHODS:A total of 57 patients(65 eyes)with dry eye after cataract surgery, who were admitted to the ophthalmology department of our hospital from September 2020 to January 2021, were selected as the research objects. They were divided into a control group(28 cases, 32 eyes, treated with 3% DQS eye drops)and an observation group(29 cases, 33 eyes, treated with 3% DQS eye drops combined with the Qingrun Yangmu oral liquid)based on a random number table method. Indicators, such as ocular surface disease index(OSDI), non-invasive tear film break-up time(NIBUT), Schirmer I test(SIt), corneal fluorescein sodium staining(CFS), and TCM symptom score, were compared and analyzed between the two groups 1d before, 1wk after(before treatment), and 1mo after(after treatment)surgery.RESULTS:The total effective rates of the observation group and the control group after treatment were 88% and 75%, respectively. The OSDI, NIBUT and SIt of the two groups after treatment showed significant improvement compared to those before treatment(P<0.05). The NIBUT, SIt, CFS, and TCM symptom scores of the observation group after treatment were better than those of the control group(P<0.05). No adverse reactions were observed in both groups.CONCLUSION:Combined use of DQS eye drops and the Qingrun Yangmu oral liquid can improve symptoms and clinical indicators of dry eye after cataract surgery, providing a new treatment method for ocular surface management of dry eye during the perioperative period of cataract surgery.

Background/Aims: Complementary and alternative medicine (CAM) is prevalent in East Asia. However, information on CAM in East Asian patients with inflammatory bowel disease (IBD) is scarce. We aimed to profile the prevalence and pattern of CAM use among East Asian IBD patients and to identify factors associated with CAM use. We also compared physicians’ perspectives on CAM. Methods: Patients with IBD from China, Japan, and South Korea were invited to complete questionnaires on CAM use. Patient demographic and clinical data were collected. Logistic regression analysis was applied for predictors of CAM use. Physicians from each country were asked about their opinion on CAM services or products. Results: Overall, 905 patients with IBD participated in this study (China 232, Japan 255, and South Korea 418). Approximately 8.6% of patients with IBD used CAM services for their disease, while 29.7% of patients sought at least 1 kind of CAM product. Current active disease and Chinese or South Korean nationality over Japanese were independent predictors of CAM use. Chinese doctors were more likely to consider CAM helpful for patients with IBD than were Japanese and South Korean doctors. Conclusions In 8.6% and 29.7% of East Asian patients with IBD used CAM services and products, respectively, which does not differ from the prevalence in their Western counterparts. There is a significant gap regarding CAM usage among different Asian countries, not only from the patients’ perspective but also from the physicians’ point of view.

Major histocompatibility complex (MHC) class II molecules, which are recognized for their primary function of presenting an antigen to the T cell receptor, are involved in various signaling pathways in B cell activation. We identified heterogeneous nuclear ribonucleoprotein (hnRNP) A2B1 as an MHC class II molecule-associated protein involved in MHC class II-mediated signal transduction in lipopolysaccharide (LPS)-stimulated 38B9 B cells. Although the function of hnRNP A2B1 in the nucleus is primarily known, the level of hnRNP A2B1 in the cytoplasm was increased in LPS-stimulated 38B9 cells, while it was not detected in the cytoplasm of non-treated 38B9 cells. The silencing of hnRNP A2B1 expression using siRNA disturbed B cell maturation by regulation of mitogen-activated protein kinase signaling, NF-κB activation, and protein kinase B activation. These results suggest that hnRNP A2B1 is associated with MHC class II molecules and is involved in B cell activation signaling pathways in LPS-stimulated 38B9 cells.

BACKGROUND: Hepatitis B virus (HBV) plays well-known roles in tumorigenesis of hepatocellular carcinoma (HCC) in infected patients. However, HBV-associated protein status in tumor tissues and the relevance to tumor behavior has not been reported. Our study aimed to examine the expression of HBV-associated proteins in HCC and adjacent nontumorous tissue and their clinicopathologic implication in HCC patients. METHODS: HBV surface antigen (HBsAg), HBV core antigen (HBcAg), and HBV X protein (HBx) were assessed in 328 HBV-associated HCCs and in 155 matched nontumorous tissues by immunohistochemistry staining. RESULTS: The positive rates of HBsAg and cytoplasmic HBx staining in tumor tissue were lower than those in nontumorous tissue (7.3% vs. 57.4%, p < .001; 43.4% vs. 81.3%, p < .001). Conversely, nuclear HBx was detected more frequently in tumors than in nontumorous tissue (52.1% vs. 30.3%, p < .001). HCCs expressing HBsAg, HBcAg, or cytoplasmic HBx had smaller size; lower Edmondson-Steiner (ES) nuclear grade, pT stage, and serum alpha-fetoprotein, and less angioinvasion than HCCs not expressing HBV-associated proteins. Exceptionally, nuclear HBx-positive HCCs showed higher ES nuclear grade and more frequent large-vessel invasion than did nuclear HBx-negative HCCs. In survival analysis, only nuclear HBx-positive HCCs had shorter disease-free survival than nuclear HBx-negative HCCs in pT1 and ES nuclear grade 1-2 HCC subgroup (median, 126 months vs. 35 months; p = .015). CONCLUSIONS: Our data confirmed that expression of normal HBV-associated proteins generally decreases in tumor cells in comparison to nontumorous hepatocytes, with the exception of nuclear HBx, which suggests that nuclear HBx plays a role in recurrence of well-differentiated and early-stage HCCs.

Objective To observe the ultrasonographic features of primary squamous cell carcinoma of the breast and its clinical and histopathological characteristics. Methods The ultrasonographic features, clinical and histopathological characteristics of 7 middle-aged women (median age 61 years old) with primary squamous cell carcinoma of the breast confirmed histopathologically from January 1995 to December 2014 in Peking Union Medical College Hospital were retrospectively reviewed. Results There were 8 lesions in seven cases. Six cases were single lesion and 1 case with multiple lesions, the diameters of the lesions were 7.0-60.0 mm [mean (34.0±19.6) mm]. On grayscale ultrasound, 6 lesions with solid compoments were hypoechoic, 2 lesions with solid and cystic compoments were complex echogenic, the lesions all had irregular shape and indistinct margin, 2 lesions had calcifications. On color Doppler flow imaging, 7 lesions had rich blood flow signals (Ⅱor Ⅲ) and 1 lesion had no blood flow signal. On gross histopathological examination, 6 masses were solid, pale-white colored, medium texture and the boundary was not clear. Two masses had cystic cavity. One old patient who was 70 years old had several times chest wall recurrence after mastectomy. On ultrasonography, the lesion showed an anechoic cyst with thick wall. Two chest wall recurrence lesions were cystic with thick wall. Microscopic examination showed squamous cell carcinoma infiltrating into the fiber adipose and skeletal muscle tissue. Conclusions Primary squamous cell carcinoma of the breast is more common in large tumor size. Ultrasound can show the more cysticcomponents of the tumor and abundant vascularity, which is helpful for diagnosis.

PURPOSE: This study was conducted to evaluate the readmission rate of preterm infants of 30-33 weeks gestational age (GA) within 1 year following discharge from the neonatal intensive care unit (NICU). METHODS: This research was a part of the Retrospective Study to Evaluate Rehospitalization & Health Care Utilization after NICU Discharge in Preterm Infants (< or =33 weeks) II (RHANPI II) project conducted by the Committee on Data Collection and Statistical Analysis of the Korean Society of Neonatology. Enrolled infants (n=1,257) of 46 hospitals from April to September 2012, were retrospectively studied. RESULTS: The average GA and birth weight of the study population was 32(+2)+/-1(+1) weeks and 1,785+/-386 g, respectively. The cumulative readmission rate during the 360 days following discharge from the NICU was 27.3%. The cumulative readmission rate according to GA was 36.4%, 30.1%, 25.9% and 22.7% for infants born at 30, 31, 32 and 33 weeks GA, respectively. The corresponding respiratory readmission rate was 16.3%; this was 59.8% of total readmissions. There was no significant difference in the respiratory readmission rate according to GA group (log-rank test for trend, P-value=0.0558). Of the infants who were readmitted with respiratory problems, 57.0% (n=53/93) tested positive for respiratory syncytial virus (RSV). CONCLUSION: The cumulative readmission rate during the 360 days following discharge from the NICU was 27.3%. Respiratory problems were the most common cause of readmission, and RSV was the most common virus associated with respiratory readmission. Additionally, there was no difference in the rate of respiratory readmission according to GA group.

BACKGROUND: The molecular profile of peritumoral non-neoplastic liver parenchyma (PNLP) has recently been suggested as predictive factor of early and late recurrence of hepatocellular carcinoma (HCC). However, there is no definite cut-off point for tumor-free PNLP in terms of either histological or molecular changes. Therefore, our aim is to determine the numerical cut-off point for separating adjacent PNLP and remote PNLP in histopathologic perspective. METHODS: Peritumoral tissues from 20 resected HCC patients were sampled from 0 to 40 mm distance from the tumor border (divided into 5-mm columns). Histopathologic parameters such as necroinflammatory activity, fibrosis, bile ductular reaction, hepatic venulitis, peliosis, and steatosis were compared between each column. RESULTS: The morphologic changes just adjacent to the tumor were notably severe and faded with distance. The parenchyma within 10 mm of the tumor showed significantly severe inflammation, fibrosis, peliosis and hepatic venulitis compared with those from farther areas. The histopathologic changes of the parenchyma became stable beyond 20 mm. CONCLUSIONS: Results of this study revealed that the parenchyma within 10 mm distance from the tumor, or adjacent PNLP, has histopathologic changes that are directly affected by the tumor, and the parenchyma beyond 20 mm as the remote PNLP without tumor effect.
