Objective: To observe the efficacy of electroacupuncture (EA) in treating dry eye syndromes (DES) and its regulatory effects on patient's quality of life (QOL), anxiety, and depression.Methods: By following a randomized controlled study design, eligible DES patients were allocated to an EA group (EAG) or an acupuncture group (AG). Patients in the AG were intervened by acupuncture alone, while in the EAG, electrical stimulation was applied to Cuanzhu (BL2) and Taiyang (EX-HN5) in addition to the same treatment in the AG. Changes in clinical manifestations, ocular surface disease index (OSDI), Schirmer tear test-1 (STT-1), tear-film break-up time (TF-BUT), cornea fluorescein staining (CFS), and corneal sensitivity (CS) were observed, as well as changes in the short-form 36-item health survey (SF-36) and hospital anxiety and depression scale (HADS) scores. Results: The scores of clinical symptoms, OSDI, and CFS decreased significantly in both EAG and AG when compared with the baseline values (P<0.05), respectively, while the TF-BUT and CS increased significantly (P<0.05), and the tear secretion of patients in the EAG increased (P<0.05). Compared with those before treatment, the scores of physical role functioning, general health perception, emotional role functioning, and mental health of patients in both EAG and AG showed significant increases after treatment (P<0.05), together with a marked decrease in the score of anxiety (P<0.05). Compared with the AG, the EAG obtained a more significant increase in STT-1 (P<0.05).Conclusion: DES patients respond well to both EA and acupuncture treatments, manifested by prolonged TF-BUT and improvement of CS. Meanwhile, the two approaches can improve QOL and reduce anxiety. Furthermore, EA appears more effective in increasing tear secretion than acupuncture alone.

OBJECTIVETo study the clinical significance of hepatitis B surface antigen (HBsAg) levels and HBsAg/hepatitis B virus (HBV) DNA ratio in relation to liver inflammation in HBeAg-positive chronic hepatitis B (CHB).
METHODSOne hundred and fifty-three Chinese patients with chronic HBV infection with HBeAg-positive status were enrolled in the study.Quantitative measurements were made for HBsAg levels by immunoassay (Architect HBsAg QT by Abbott Diagnostic) and HBV DNA by real-time fluorescence quantitative PCR.Levels of liver function markers were measured by standard methods.Liver biopsy specimens were obtained from all patients and used to score the histology (liver inflammation) activity index (HAI) and grade (G) the extent of necroinflammation.Statistical correlation analysis was performed to determine the association of HBsAg titre or HBsAg/HBV DNA ratio with the various parameters of liver injury.
RESULTSHBsAg titre and HBsAg/HBV DNA ratio were significantly correlated (r =0.578, P less than 0.0001).A significant positive correlation (r =0.642, P less than 0.0001) was found between HBsAg titre and HBV DNA load, and a significant negative correlation was found between the HAI and HBsAg (r =-0.389, P less than 0.0001) and HBsAg/HBV DNA ratio (r =-0.307, P=0.000l).A significant positive correlation was found between alanine aminotransferase (ALT) level and the HAI (r =0.480, P less than 0.0001).Patients with G less than 2 necroinflammation had significantly higher HBsAg titre and HBsAg/HBV DNA ratio than patients with G more than or equal to 2 necroinflammation (both P less than 0.01) but similar levels ofHBV DNA.Generation of a receiver operating characteristic curve using G more than or equal to 2 as the positive index provided the following area under the curve (AUC) values:HBsAg titre, 0.700; HBsAg/HBV DNA ratio, 0.672; ALT level, 0.713.When the random chance AUC was 0.5, all levels of AUC were statistically significant (Pless than 0.001).HBsAg titre (sensitivity =76.92%) was more sensitive than ALT level (sensitivity =76.92%), and HBsAg/HBV DNA ratio (specificity =81.33%) was more specific than ALT level (specificity =81.33%).Youden's index for comprehensive evaluation using ALT was higher than those for HBsAg titre or HBsAg/HBV DNA ratio.When HBsAg and ALT were considered in parallel, the sensitivity increased to 94.08% and specificity rose to 85.60%.
CONCLUSIONHBsAg titre, HBsAg/HBV DNA ratio and ALT levels can be used as the index for judging the degree of liver inflammation in HBeAg-positive CHB patients.Higher sensitivity and specificity are attained when HBsAg and ALT are used in series or parallel.

Objective:To evaluate the clinical efficacy, tolerability and safety of adjunctive perampanel in focal epilepsy patients≥12 years old.Methods:One hundred and nineteen focal epilepsy patients≥12 years old accepted adjunctive perampanel in Department of Neurology, First Affiliated Hospital of Guangxi Medical University from July 2020 to December 2022 were chosen. At 1-3 months, 4-6 months, 7-9 months and 10-12 months after adjunctive perampanel, seizure frequency changes every 28 d, medication retention rate and adverse reactions were recorded to evaluate the clinical efficacy (a reduction in seizure frequency≥50% from baseline was defined as overall valid treatment), tolerability and safety of adjunctive perampanel. According to efficacy results after adjunctive perampanel of 4-6 months (short-term) and 10-12 months (long-term), these patients were divided into valid group and invalid group; and the influencing factors for short-term and long-term efficacy were analyzed.Results:At 1-3, 4-6, 7-9, 10-12 months after adjunctive perampanel, reduction in seizure frequency every 28 d was 66.7% (24.3%, 97.2%), 77.5% (48.6%, 100%), 94.6% (50%, 100%), 100% (70.9%, 100%), enjoying overall valid rate of 60.2% (59/98), 75.0% (7/76), 78.9% (45/57), 86.5% (32/37). The retention rate at 3, 6, 9 and 12 months after adjunctive perampanel was 85.2% (98/115), 67.9% (76/112), 54.3% (57/105), 41.1% (37/90). Adverse reactions were reported in 33 patents (27.7%), mainly with dizziness and secondly with mental symptoms. After short-term and long-term adjunctive perampanel, no significant difference was noted in gender, initial age of adjunctive perampanel, course of disease, etiology, EEG results, imaging results, number and type of combined anti-seizure drugs, or maximum dose of pirampanel between the valid group and invalid group ( P>0.05). Conclusion:Perampanel has good efficacy, tolerability and safety in adolescents and adults≥12 years old with focal epilepsy; no clear influencing factors for pirampanel valid treatment is found so far.

PURPOSE: Although the effect of lysosome-associated protein transmembrane 4 beta (LAPTM4B) on the proliferation, migration, and invasion of breast cancer (BC) cells has already been studied, its specific role in BC progression is still elusive. Here, we evaluated the effect of different levels of LAPTM4B expression on the proliferation, invasion, adhesion, and tumor formation abilities of BC cells in vitro, as well as on breast tumor progression in vivo. METHODS: We investigated the influence of LAPTM4B expression on MCF-7 cell proliferation, invasion, adhesion, and tube formation abilities in vitro through its overexpression or knockdown and on breast tumor progression in vivo. RESULTS: Cell growth curves and colony formation assays showed that LAPTM4B promoted the proliferation of breast tumor cells. Cell cycle analysis results revealed that LAPTM4B promoted the entry of cells from the G1 into the S phase. Transwell invasion and cell extracellular matrix adhesion assays showed that LAPTM4B overexpression increased the invasion and adhesion capabilities of MCF-7 cells. More branches were observed in MCF-7 cells overexpressing LAPTM4B under an electron microscope. In comparison with LAPTM4B overexpression, LAPTM4B knockdown decreased the expression of vascular endothelial growth factor-A and significantly inhibited the vasculogenic tube formation ability of tumors. These results were also verified with western blot analysis. CONCLUSION: LAPTM4B promoted the proliferation of MCF-7 cells through the downregulation of p21 (WAF1/CIP1) and caspase-3, and induced cell invasion, adhesion, and angiogenesis through the upregulation of hypoxia-inducible factor 1 alpha, matrix metalloproteinase 2 (MMP2), and MMP9 expression. This specific role deems LAPTM4B as a potential therapeutic target for BC treatment.
