Autophagy is a highly conserved cellular degradation pathway that degrades lipid droplets through a process called"lipophagy".Lipophagy can selectively recognize lipid substances and degrade them,promoting β oxidation and thereby maintaining the balance of intracellular lipid metabolism.The liver regulates lipid droplet metabolism through lipophagy signaling pathways or key molecules,thereby alleviating hepatic steatosis and improving nonalcoholic fatty liver disease(NAFLD).This article reviews the latest advances in the degradation of hepatic lipid droplets through the three autophagic pathways of macroautophagy,molecular chaperone-mediated autophagy,and microautophagy.The major signaling pathways of AMPK/mTOR-ULK1,ATGL-SIRT1,FGF21-JMJD3,and Akt are involved in the regulation of the lipophagy process and help to maintain the homeostasis of lipid metabolism in the liver,so as to provide new ideas for clinical prevention and treatment of NAFLD.

Objective:To evaluate the efficacy and safety of transepithelial photorefractive keratectomy (Trans-PRK) combined with accelerated corneal cross-linking (CXL) for refractive error in patients with thin or irregular corneas, excluding keratoconus.Methods:An observational case series study was performed.Fifty-five right eyes of 55 myopic patients diagnosed with thin or irregular corneas, who underwent Trans-PRK combined with prophylactic CXL surgery, were included at Baotou Chaoju Eye Ophthalmic Hospital from August 2017 to July 2018.Uncorrected distance visual acuity (UDVA) of the operated eye was measured using international standard visual acuity charts, and refractive diopters were measured by computer and comprehensive refraction before surgery and at 1 week, 1, 3, 6, and 12 months after surgery.Corneal morphology was assessed with the Pentacam anterior segment analyzer before surgery and at 3, 6, and 12 months after surgery.Intraocular pressure (IOP) was measured with a non-contact tonometer before surgery and at 1, 3, 6, and 12 months after surgery.The incidence of postoperative complications was recorded.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Baotou Chaoju Ophthalmic Hospital (No.btcj-u-1). Written informed consent was obtained from each subject.Results:Preoperative, 1-week, 1-, 3-, 6-, and 12-month postoperative UDVA (LogMAR) were 0.52(0.55, 0.78), 0.22(0.12, 0.17), 0.10(0.04, 0.07), 0.00(-0.04, -0.16), -0.08(-0.05, -0.03) and -0.08(-0.06, -0.04), respectively, showing a statistically significant overall difference ( Z=249.44, P<0.001). UDVA at each postoperative time point was improved compared to preoperative, and UDVA at 3, 6, and 12 months postoperatively was significantly improved compared to 1 week and 1 month postoperatively (all at P<0.001). The spherical diopter at each postoperative time point decreased significantly compared to preoperative, with the spherical diopter at 1, 3, 6, and 12 months postoperatively being lower than that at 1 week postoperatively, and the 12-month postoperative spherical diopter being lower than that at 3 and 6 months postoperatively, showing statistically significant differences (all at P<0.001). The cylindrical degree at 1, 3, 6, and 12 months postoperatively was lower than that at preoperative and 1 week postoperatively, with statistically significant differences (all at P<0.05). After the operation, the spherical equivalent of the operated eye gradually decreased with time, tending toward emmetropia.The spherical equivalent at each postoperative time point decreased compared to preoperative, with the spherical equivalent at 1, 3, 6, and 12 months postoperatively being lower than that at 1 week postoperatively, and the spherical equivalent at 12 months postoperatively being lower than that at 3 and 6 months postoperatively, showing statistically significant differences (all at P<0.001). The corneal K1 and K2 values at 3, 6, and 12 months postoperatively were significantly lower than preoperatively (all at P<0.001), and the corneal K1 and K2 values at 3 months postoperatively tended to stabilize.The IOP of the operated eye at 3, 6, and 12 months postoperatively was significantly lower than preoperatively, and the IOP at 6 and 12 months postoperatively was lower than that at 1 and 3 months postoperatively, with statistically significant differences (all at P<0.001). One eye developed grade 0.5 corneal haze at 1 week postoperatively, which spontaneously resolved to transparency at 1 month postoperatively. Conclusions:Trans-PRK combined with accelerated CXL has good efficacy, stability and safety for refractive error patients with thin or irregular corneas, except for keratoconus.

Objective To explore the biological effect of transcription factor B1,mitochondrial(TFB1M)on hepatocellular carcinoma(HCC)cells,and to explore the molecular mechanism of its regulation on malignant metastasis of HCC.Methods The expression level of TFB1M in liver cancer and its relationship with clinical characteristics of patients with HCC was analyzed based on TCGA-LIHC and GEO databases.Based on the median expression level of TFB1M,the TCGA-LIHC samples were divided into low expression group of TFB1 M(n=170)and high expression group of TFB1M(n=170),and GSEA was used for gene set enrichment analysis.The overexpressed TFB1M plasmid was constructed to transfect HepG2 and Huh7 cells.Cell migration and invasion were assessed by scratch healing and Transwell chamber assays.Results The expression of TFB1M was significantly decreased in HCC,and the expression of TFB1M was related with gender in HCC.The results of GSEA analysis indicated that the low expression of TFB1M might be related to liver cancer subclass proliferation up gene set,stem cell hepatocellular carcinoma gene set,and extracellular matrix assembly gene set in HCC.Overexpression of TFB1M remarkably attenuated the migration and invasion activity of HCC cells.Conclusions The expression of TFB1M was significantly decreased in HCC,and overexpression of TFB1M could attenuated the migration and invasion activity of HCC cells.

Na⁺/H⁺ antiporter (NHX) gene subfamily plays an important role in plant response to salt stress. In this study, we identified the NHX gene family members of Chinese cabbage and analyzed the expression patterns of BrNHXs gene in response to abiotic stresses such as high temperature, low temperature, drought and salt stress. The results showed that there were 9 members of the NHX gene family in Chinese cabbage, which were distributed on 6 chromosomes respectively. The number of amino acids was 513-1 154 aa, the relative molecular weight was 56 804.22-127 856.66 kDa, the isoelectric point was 5.35-7.68. Members of BrNHX gene family mainly existed in vacuoles, the gene structure is complete, and the number of exons is 11-22. The secondary structures of the proteins encoded by the NHX gene family in Chinese cabbage had alpha helix, beta turn and random coil, and the alpha helix occurred more frequently. Quantitative real-time PCR (qRT-PCR) analysis showed that the gene family members had different responses to high temperature, low temperature, drought and salt stress, and their expression levels differed significantly in different time periods. BrNHX02 and BrNHX09 had the most significant responses to these four stresses, and their expression levels were significantly up-regulated at 72 h after treatments, which could be used as candidate genes to further verify their functions.

OBJECTIVES: Surgical robot system has broken the limitation of traditional surgery and shown excellent performance in surgery, and has been widely used in minimally invasive treatment in most areas of surgery. This study aims to verify the basic performance of the domestic surgical robot system and the safety and effectiveness of the integrated bipolar electrocoagulation and ultrasonic knife. METHODS: The basic performance of the domestic surgical robot system was evaluated by completing the square knot and surgical knot, vertical and horizontal perforation and right ring perforation and suture, as well as picking up beans. Compared with laparoscopy, the safety and effectiveness of the domestic surgical robot after integrated interconnection bipolar electrocoagulation and ultrasonic scalpel were evaluated by detecting the vascular closure performance and the degree of histopathological damage in animals. RESULTS: Compared with freehand knotting, domestic robot knotting speed and circumference were slightly worse, but better than laparoscopic knotting. There was no statistical significance in the tension difference of the surgical knots among the 3 methods (P>0.05), but the tension of the square knots made by the freehand and the domestic surgical robot was greater than that of the laparoscopy (P<0.05). The space required for both the left and right forceps heads of knots was smaller than that of laparoscopy (P<0.001), which successfully completed the 4 quadrant suture tasks, and the time of picking up beans was significantly less than that of laparoscopy (P<0.05). There was no significant difference in the temperature of the liver tissue after the bipolar electrocoagulation between the interconnected domestic surgical robot and the laparoscopy (P>0.05), and the acute thermal injury was observed under the light microscope. The temperature of the liver tissue treated by the domestic robotic ultrasound knife was higher than that of the laparoscopic ultrasound knife (P<0.05). CONCLUSIONS Domestic surgical robots are obviously superior to laparoscopy in suturing, knotting, and moving objects, and domestic surgical robots' interconnect bipolar electrocoagulation and ultrasonic knife have achieved success in animal experiments, and hemostasis is considered to be safe and effective.

In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.

Objective : To study the effect of lipopolysaccharide ( LPS) -induced immune system activation on syn- aptic structure and DISC1. Methods : 40 rats were divided into 4 groups，which were PBS group，PBS + MK-801 group，LPS group and LPS + MK-801 group．The rats in LPS group and LPS + MK-801 group were administrated with LPS solution (0. 2 mg / kg，i．p．BIW) for 6 times in total， the rats in PBS group and PBS + MK801 group were administrated with PBS．At the third time when the rats were administrated with LPS solution，the rats in PBS + MK-801 group and LPS + MK-801 group were administrated with MK-801 solution (0. 5 mg / kg，i．p．BIW) for a total of 4 times，the rats in PBS group and LPS group were adminis- trated with saline．The head shaking and the open field tests were then evaluated in the rats．Immediately，the rats were sacrificed，and their brain were saved for testing. RT-qPCR , Golgi staining，immunohistochemistry and ELISA kits were used to detect DISC1 gene expression，dendritic spine status，microglia activation and inflammatory cytokine content in cortex，respectively. gene expression in the cortex of rats with schizophrenia． Results : Compared with the PBS group，the expression of DISC1 gene of the rats in the PBS + MK-801 group increased (P ＜0. 01) ，the score of head shaking increased (P ＜0. 01) ，and the distance of the open field increased (P ＜0. 000 1) ; As well as the LPS + MK-801 group，compared with the LPS group，the expression of DISC1 gene increased (P＜0. 000 1) ，the head shaking score and the distance of the open field increased (P＜0. 000 1) . In addition，compared with the PBS + MK-801 group，the expression of DISC1 gene， the shaking head score and the open field distance of the LPS + MK-801 group further improved (P ＜0. 000 1) . Furthermore，compared with PBS group and PBS + MK-801 group，the content of iba1 in the cortex of LPS group and LPS + MK-801 group significantly increased (P ＜0. 05 ) ，the content of inflammatory cytokines significantly increased (P＜0. 05) ，and the length and density of dendritic spines significantly decreased (P＜0. 05) ． Conclusion The activation of the immune system induced by LPS can contribute to the susceptibility of schizophrenia model， and the possible mechanism is that it cooperates with MK-801 to increase the expression of DISC1 gene，which ulti- mately leads to abnormal mental behavior in rats.

ObjectiveTo analyze the changing trend of cerebrovascular disease burden in Minhang District of Shanghai from 1996 to 2021， and to provide scientific evidence for government to formulate targeted cerebrovascular disease prevention and control strategies. MethodsMortality， years of life lost（YLL）， years of lived with disability（YLD） and disability⁃adjusted life years（DALY） were used to evaluate the burden of cerebrovascular diseases in Minhang District. Joinpoint linear regression was used to analyze the trend of disease burden. ResultsFrom 1996 to 2021， the YLL rate of cerebrovascular diseases in Minhang District showed a downward trend （whole population： APC=-1.69%， t=-6.9， P<0.05）， The YLD rate of cerebrovascular diseases showed a slow upward trend （whole population： APC=1.17%， t=3.5， P<0.05）， The DALY rate of cerebrovascular diseases showed a downward trend， and fluctuated since 2003 （whole population： APC= -1.43%， t=-5.6， P<0.05）. The YLL rate of cerebrovascular diseases in men was higher than that in women， and the YLD rate of cerebrovascular diseases in women was higher than that in men. After 2014， the DALY of cerebrovascular diseases in men was higher than that in women. With the increase of age， the burden of cerebrovascular diseases increased， and the burden of disease increased significantly in the age group above 70. ConclusionThe burden of cerebrovascular diseases in Minhang District is at a high level， and there are differences in age， gender and other aspects. Measures such as screening， intervention and rehabilitation need to be improved to reduce disability and premature death caused by cerebrovascular diseases and to reduce the burden of cerebrovascular diseases on individuals， families and society.

Background::Although existing mycological tests (bronchoalveolar lavage [BAL] galactomannan [GM], serum GM, serum (1,3)-β-D-glucan [BDG], and fungal culture) are widely used for diagnosing invasive pulmonary aspergillosis (IPA) in non-hematological patients with respiratory diseases, their clinical utility in this large population is actually unclear. We aimed to resolve this clinical uncertainty by evaluating the diagnostic accuracy and utility of existing tests and explore the efficacy of novel sputum-based Aspergillus assays. Methods::Existing tests were assessed in a prospective and consecutive cohort of patients with respiratory diseases in West China Hospital between 2016 and 2019 while novel sputum assays (especially sputum GM and Aspergillus-specific lateral-flow device [LFD]) in a case-controlled subcohort. IPA was defined according to the modified European Organization for Research and Treatment of Cancer/Mycoses Study Group criteria. Sensitivity and specificity were computed for each test and receiver operating characteristic (ROC) curve analysis was performed. Results::The entire cohort included 3530 admissions (proven/probable IPA = 66, no IPA = 3464) and the subcohort included 127 admissions (proven/probable IPA = 38, no IPA = 89). Sensitivity of BAL GM (≥1.0 optical density index [ODI]: 86% [24/28]) was substantially higher than that of serum GM (≥0.5 ODI: 38% [39/102]) ( χ2 = 19.83, P < 0.001), serum BDG (≥70 pg/mL: 33% [31/95]) ( χ2 = 24.65, P < 0.001), and fungal culture (33% [84/253]) ( χ2 = 29.38, P < 0.001). Specificity varied between BAL GM (≥1.0 ODI: 94% [377/402]), serum GM (≥0.5 ODI: 95% [2130/2248]), BDG (89% [1878/2106]), and culture (98% [4936/5055]). Sputum GM (≥2.0 ODI) had similar sensitivity (84% [32/38]) (Fisher’s exact P = 1.000) to and slightly lower specificity (87% [77/89]) ( χ2 = 5.52, P = 0.019) than BAL GM (≥1.0 ODI). Area under the ROC curve values were comparable between sputum GM (0.883 [0.812-0.953]) and BAL GM (0.901 [0.824-0.977]) ( P = 0.734). Sputum LFD had similar specificity (91% [81/89]) ( χ2 = 0.89, P = 0.345) to and lower sensitivity (63% [24/38]) ( χ2 = 4.14, P = 0.042) than BAL GM (≥1.0 ODI), but significantly higher sensitivity than serum GM (≥0.5 ODI) ( χ2 = 6.95, P = 0.008), BDG ( χ2 = 10.43, P = 0.001), and fungal culture ( χ2 = 12.70, P < 0.001). Conclusions::Serum GM, serum BDG, and fungal culture lack sufficient sensitivity for diagnosing IPA in respiratory patients. Sputum GM and LFD assays hold promise as rapid, sensitive, and non-invasive alternatives to the BAL GM test.
