Based on advancements in modern medical research regarding the intricate connection between the endocrine and exocrine functions of the pancreas， as well as the relationship between pancreatic functions and traditional Chinese medicine （TCM） spleen system， this paper discussed the categorization of the pancreas. It is proposed that the pancreas is neither a true zang organ nor a fu organ， but possessed the attributes of an extraordinary fu-organ and can be classified under the spleen. The spleen governs transportation and transformation， ascent of the clear and dispersion of essence， which encompasses the endocrine and exocrine functions， and pancreatic enzymes and glucose-regulating hormones form the material basis for the spleen's function of dispersing essence. Diseases of the pancreas exhibit characteristics of both zang-organ deficiency and fu-organ excess， so treatment should simultaneously supplement zang-organ disease and regulate fu-organ disease when pancreas showing endocrine and exocrine co-morbidities， with focus on restoring the pancreas （spleen）'s dispersing essence function. Therapeutic strategies include supplementing spleen qi， nourishing spleen yin to strengthen spleen earth， unblocking spleen collaterals， raising spleen yang， and removing spleen turbidity to support the spleen's dispersing essence function， so as to replenish the essential qi of zang-fu organs， ensure their distribution throughout the body， and improve the endocrine and exocrine functions of the pancreas.

The liver regenerative capacity is crucial for patients with end-stage liver disease following partial hepatectomy (PHx). The specific bacteria and mechanisms regulating liver regeneration post-PHx remain unclear. This study demonstrated dynamic changes in the abundance of Parabacteroides distasonis (P. distasonis) post-PHx, correlating with hepatocyte proliferation. Treatment with live P. distasonis significantly promoted hepatocyte proliferation and liver regeneration after PHx. Targeted metabolomics revealed a significant positive correlation between P. distasonis and β-hydroxybutyric acid (BHB), as well as hyodeoxycholic acid and 3-hydroxyphenylacetic acid in the gut after PHx. Notably, treatment with BHB, but not hyodeoxycholic acid or 3-hydroxyphenylacetic acid, significantly promoted hepatocyte proliferation and liver regeneration in mice after PHx. Moreover, STAT3 inhibitor Stattic attenuated the promotive effects of BHB on cell proliferation and liver regeneration both in vitro and in vivo. Mechanistically, P. distasonis upregulated the expression of fatty acid oxidation-related proteins, and increased BHB levels in the liver, and then BHB activated the STAT3 signaling pathway to promote liver regeneration. This study, for the first time, identifies the involvement of P. distasonis and its associated metabolite BHB in promoting liver regeneration after PHx, providing new insights for considering P. distasonis and BHB as potential strategies for promoting hepatic regeneration.

Atherosclerosis is a chronic vascular inflammatory disease caused by abnormal lipid metabolism.The formation of lipid-rich foam cells acts as the initial trigger for development of atherosclerotic lesions.Recent studies have shown that lipophagy,a form of selective autophagy,can selectively degrade lipid droplets stored intracellularly and promote cholesterol efflux through the autophagic lysosomal pathway.As a result,intracellular lipid accumulation is re-duced and foaming is inhibited,making lipophagy a potential new target for current anti-atherosclerosis therapy.This arti-cle reviews the crucial role and molecular mechanism of lipophagy in the link between lipid metabolism and atherosclero-sis.Its objective is to outline the regulatory mechanism of lipophagy and present fresh insights for the treatment of athero-sclerotic diseases.

The patients were grouped and numbered according to their ethnicity, and the spherical equivalent and axial length were obtained by using an autorefractor and IOL Master. The blood flow images of the macular area in the range of 3 mm×3 mm were obtained by using a DRI Triton OCT detector, and the images were analyzed by using the built-in IMAGENET6 software to obtain the blood flow parameters. Furthermore, the differences in the blood flow parameters between different ethnic groups as well as the effects of gender, age, and axial length on macular blood flow parameters of different ethnic groups were compared.RESULTS:There were no statistically significant differences in gender, age, axial length, diopter, and image quality(IQ)among the four groups of subjects(all P>0.05). Ethnic differences: in SCP, Uyghur inferior VD is higher than Kazakh, Hui inferior VD is higher than Han and Kazakh, Han and Hui nasal VD is higher than Uyghur, Kazakh foveal VD is higher than Han and Hui, Kazakh FAZ area is smaller than the other 3 ethnic groups, Han and Hui FAZ perimeter is larger than Kazakh, and Hui FAZ circularity index is lower than the other 3 ethnic groups; in DCP, Uyghur foveal VD is higher than Han and Hui, Kazakh foveal VD is higher than Han and Hui, Kazakh FAZ area and perimeter are smaller than the other 3 ethnic groups and Kazakh FAZ circularity index is higher than the other 3 ethnic groups(all P<0.05). Sex differences: in SCP, FAZ area and perimeter of Han females were larger than those of males, and FAZ circularity index of Hui females was higher than that of males(all P<0.05); in DCP, parafoveal VD and whole VD in females of all four ethnic groups were higher than those of males(all P<0.05). Age correlation: in SCP, age was negatively correlated with the FAZ circularity index of Kazakh; in DCP, age was negatively correlated with the parafoveal and the whole VD of Han, Kazakh, and Hui(all P<0.05). Axial length correlation: in SCP, the axial length was negatively correlated with Kazakh and Hui foveal VD, Hui parafoveal VD, Uyghur, Kazakh and Hui whole VD, and positively correlated with Kazakh FAZ area and perimeter; in DCP, the axial length was negatively correlated with Uyghur, Kazakh, Hui foveal VD, Hui whole VD, and positively correlated with Kazakh and Hui FAZ area and perimeter(all P<0.05).CONCLUSION:There were differences in macular blood flow parameters among the Uyghur, Han, Kazakh, and Hui populations, with the area and perimeter of the FAZ of the Kazakh significantly smaller than those of the other three ethnic groups. Gender, age, and axial length are also related to macular blood flow parameters.

OBJECTIVE To investigate the effects of Setaria italica extract on improving insomnia model mice and to explore its potential mechanisms. METHODS The mice were randomly assigned into blank group， model group， positive control group （diazepam， 2.6 mg/kg）， and S. italica extract low-dose， medium-dose and high-dose groups （1.2， 2.4， 4.8 g/kg）， with 10 mice in each group. Except for the blank group， all other groups received intraperitoneal injection of para-chlorophenylalanine （PCPA） to establish the insomnia model. After modeling， the blank group and model group were given a constant volume of normal saline intragastrically， and administration groups were given relevant medicine intragastrically， with a volume of 0.01 mL/g， once a day， for 7 consecutive days. After the administration， the open-field test was conducted to observe the praxiological changes of mice， and to determine the levels of 5-hydroxytryptamine （5-HT） and 5-hydroxyindoleacetic acid （5-HTAA） in the hippocampal tissue， as well as the contents of 5-HT， brain-derived neurotrophic factor （BDNF）， interleukin-2 （IL-2）， IL-6， B-cell lymphoma-2 （Bcl- 2）， and Bcl-2-associated X protein （Bax） in the serum. The expression of phosphoinositide 3-kinase/protein kinase B/nuclear factor- κB （PI3K/Akt/NF-κB） signaling pathway related protein was determined in the hippocampus of mice. RESULTS Compared with the model group， the total exercise time of mice in S. italica extract high-dose group was significantly prolonged， but the total rest time was significantly shortened （P＜0.01）； the number of standing times and modification times were significantly reduced （P＜ 0.01）. The contents of 5-HT， BDNF， and Bcl-2 in serum， and Bcl-2/Bax were significantly increased， while the contents of IL-2， IL-6， and Bax were significantly reduced （P＜0.05 or P＜ 0.01）. The content of 5-HTAA in the hippocampal tissue and 202104010910029）；the phosphorylation levels of PI3K and Akt proteins were increased significantly， while the phosphorylation level of NF-κB p65 protein was decreased significantly （P＜0.05）.CONCLUSIONS High-dose of S. italica extract demonstrates significant therapeutic effects on insomnia in mice， and the mechanism of which may be associated with the regulation of PI3K/Akt/NF-κB signaling pathway.

ObjectiveThe glycosidic linkage structural characteristics of polysaccharides from Pinelliae Rhizoma（PR） and its processed products were analyzed by sugar spectrum， high performance thin layer chromatography（HPTLC）， fluorescence-assisted carbohydrate gel electrophoresis（PACE） based on partial acid hydrolysis and specific glycosidase hydrolysis， and the antioxidant activities of polysaccharides before and after hydrolysis（enzymolysis） were compared. MethodPolysaccharides from PR and its processed products were extracted by ultrasound extraction， starch was hydrolyzed by α-amylase， and small molecules below 3 kDa were removed by ultrafiltration. The purified polysaccharides were prepared by hydrolysis of acid and five different specific glycosidases， and the hydrolysates were analyzed by HPTLC and PACE. The antioxidant capacity of polysaccharides was analyzed by 2，2′-azino-bis（3-ethylbenzthiazoline-6-sulfonic acid）（ABTS） and 2，2-diphenyl-1-picrylhydrazyl（DPPH） free radical scavenging experiment before and after different hydrolysis. ResultThrough HPTLC and PACE analysis， it was found that polysaccharides from PR and its processed products could be hydrolyzed by β-galactosidase， β-mannase， cellulase and pectinase， but hardly hydrolyzed by glucanase， indicating that the polysaccharides contained β-galactopyranoside bond， β-1，4-mannoside bond， β-1，4-glucoside bond and α-1，4-galacturonic acid glycosidic bond. In vitro antioxidant experiments showed that the ABTS radical scavenging capacity of the polysaccharides from PR and its processed products was weakened after acid hydrolysis and pectinase enzymatic hydrolysis， while the ABTS radical scavenging capacity was enhanced after enzymatic hydrolysis with cellulase， β-galactosidase， and β-mannase. And after different hydrolysis， the DPPH free radical scavenging capacity of polysaccharides from PR and its processed products was all significantly enhanced. ConclusionThe glycosidic linkage structural characteristics of polysaccharides from PR and its processed products was analyzed by sugar spectrum in this paper， and the relationship between glycosidic bond types and their antioxidant activity was clarified through in vitro antioxidant experiments， which is beneficial for further elucidating the material basis of the related efficacy of PR and its processed products， and providing new ideas and methods for analyzing the structural characteristics of polysaccharides in Chinese medicines.

Corneal refractive surgery, a widely adopted method for correcting refractive errors, has demonstrated its safety, efficacy, and predictability in extensive research. Studies indicate varying degrees of intraoperative fluctuations inintraocular pressure, potentially impacting the posterior segment structures and functions due to surgical techniques, equipment, technical proficiency, and patient-specific factors. Although short-term postoperative follow-up in most patients does not reveal visual dysfunction, the long-term effects and potential risks of transient high intraocular pressure during surgery on the posterior segment structures and functions remain unclear. Therefore, the assessment of posterior segment complications following corneal refractive surgery is of paramount importance in clinical practice. This review aims to explore the characteristics of intraocular pressure fluctuations during corneal refractive surgery and their effects on structures and functions of the vitreous, retina, and optic nerve in the posterior segment, analyze possible causes and risk factors, discuss their implications for current clinical treatment, and consider future trends, providing insights for clinical practice.

AIM: To analyze the changes of the dominant eye in myopic patients after small incision lenticule extraction(SMILE)and its effect on visual quality.METHODS: Prospective clinical study. A total of 140 patients(280 eyes)who underwent SMILE operation to correct myopia in the First Affiliated Hospital of Xinjiang Medical University from June to December 2022 were selected. They were divided into dominant eye transformation group(46 cases, 92 eyes)and non-transformation group(94 cases, 188 eyes)according to whether the dominant eye transformation occurred during the follow-up in postoperative 3 mo. The uncorrected visual acuity(UCVA)of the two groups was evaluated, the subjective visual quality was evaluated by the quality of life impact of refractive correction(QIRC)scale, and the objective visual quality was evaluated by measuring the high-order aberrations of the whole eye before and at 1 and 3 mo after surgery.RESULTS: Before SMILE, the right type of dominant eye was 105 cases, left-type was 35 cases. There were 46 cases had change at 1 mo postoperatively, and there was no new change at 3 mo after operation than 1 mo after operation. There was no significant difference in UCVA and QIRC scale score between the two groups preoperatively and at 1 and 3 mo postoperatively(P>0.05). Comparison of the dominant eye between the two groups: the total higher-order aberrations and spherical aberrations at 3 mo postoperatively were significantly higher than those in the non-transformed group(P=0.030, 0.046); Comparison of the non-dominant eye between the two groups: trefoil in the transformed group at 1 mo postoperatively was significantly higher than that in the non-transformed group(P=0.008). The binocular difference of trefoil in the transition group was significantly higher than that in the non-transition group at 1 mo after surgery(P=0.022), with no differences in the rest parameters.CONCLUSION: Some patients may experience a change in the dominant eye after SMILE surgery, with no significant impact on subjective visual quality. The decrease of objective visual quality in the early postoperative period may be an associated factor in the dominant eye transformation.

Objective:To investigate the clinical efficacy of three-connections and four-screwings technique in the treatment of high double column acetabular fractures through a single ilioinguinal approach.Methods:A retrospective study was conducted to analyze the data of 42 patients who had been treated for high double column acetabular fractures from June 2017 to June 2020 at Trauma Ward 2, Department of Orthopedics and Traumatology, The First Hospital of Traditional Chinese Medicine of Changde. There were 19 males and 23 females with an age of (42.7±25.6) years. 29 injuries were due to a traffic accident, 12 ones to fall from a height, and one to fall. The time from injury to operation was (4.5±2.1) days. All the patients were treated by the three-connections and four-screwings technique through a single ilioinguinal approach. Briefly, the anterior column was connected and secured to the main bone using 3 routes, and the posterior column was attached and fixated to the anterior column reset using 2 or 3 of the 4 screwings. The operation time, intraoperative blood loss, fracture reduction quality, fracture healing time, hip function at the last follow-up and complications during the follow-up were recorded.Results:For this cohort, the operation time was (150.0±30.5) min, and intraoperative blood loss (300.0±50.0) mL. According to the Matta scale for postoperative acetabular fracture reduction, 34 cases were excellent, 6 cases good, and 2 cases acceptable, with an excellent and good rate of 95.2% (40/42). After operation one patient had fat liquefaction and wound exudation which responded to drainage and dressing change. The 42 patients were followed up for (15.0±3.4) months. All fractures healed after (11.0±2.0) months. By the modified Merle d'Aubigné & Postel scoring system, the hip function was evaluated at the last follow-up as excellent in 33 cases, as good in 6 cases, and as fair in 3 cases, yielding an excellent and good rate of 92.9% (39/42).Conclusions:In the treatment of high double column acetabular fractures, the three-connections and four-screwings technique through a single ilioinguinal approach can lead to fine reduction and rigid fixation by lag screw compression and neutralization plate protection. Consequently, early functional exercises can be performed to secure good therapeutic outcomes for the patients.
