As one of the most common malignant tumors， digestive system tumors exhibit an increase in the incidence and mortality year by year. Its pathogenesis is complex， making it difficult to carry out early prevention. Autophagy is a process in which cells use lysosomes to degrade their organelles and macromolecules to maintain cellular homeostasis under the regulation of autophagy-related genes. Cellular autophagy has a dual regulatory effect on the tumor microenvironment， which always affects the occurrence and development of digestive system tumors. Therefore， the effect and mechanism of action of cellular autophagy on digestive system tumors have become a hot topic in tumor therapy in recent years. Meanwhile， the remarkable research results of targeted autophagy drugs indicate that cellular autophagy may become an important target for anti-digestive system tumors. Traditional Chinese medicine （TCM） has been widely used in the comprehensive treatment of digestive system tumors with good efficacy. A variety of active ingredients in TCM， such as flavonoids， glycosides， terpenoids， quinones， and alkaloids， can increase the expression of autophagy-associated proteins microtubule-associated protein 1 light chain 3 （LC3）Ⅱ/Ⅰ， autophagy-related gene （ATG）5， ATG7， inhibit the expression of autophagy-related protein p62 ， and induce autophagy in digestive system tumor cells， thereby exerting the anti-digestive system tumor effect. By summarizing the research results in recent years on the modulation of cell autophagy by active ingredients in TCM to fight against digestive system tumors， this paper analyzed the relevant signaling pathways， regulatory factors， and functional characteristics of cell autophagy modulation， so as to elucidate the mechanism by which active ingredients of TCM induce autophagy and to provide ideas and references for clinical application.

OBJECTIVE To investigate the efficacy and safety of tirofiban for early neurological deterioration in patients with acute ischemic stroke. METHODS A total of 126 patients with early neurological deterioration of acute ischemic stroke who were admitted to the Department of Neurology， Heji Hospital Affiliated to Changzhi Medical College from January 2022 to December 2023 were selected and divided into observation group and control group according to random number table method， with 63 cases in each group. All patients received standardized treatment such as lipid-lowering and blood pressure-lowering therapy. Based on the standard treatment， patients in the control group additionally took Aspirin enteric-coated tablets 100 mg+Clopidogrel bisulfate tablets 75 mg orally （once a day， for 14 consecutive days）. The patients in the observation group received Tirofiban hydrochloride and sodium chloride injection based on the standardized treatment [first intravenous infusion of 0.40 μg/（kg·min） for 30 min， and then continuous intravenous infusion of 0.10 μg/（kg·min） for 47.5 h]； subsequently， patients were given Aspirin enteric-coated tablets （100 mg） and Clopidogrel bisulfate tablets （75 mg） once a day for 14 consecutive days. The clinical efficacy， the National Institutes of Health Stroke Scale （NIHSS） score， modified Rankin Scale （mRS） score， and hemorheological indexes before and after treatment were compared between the two groups， and the adverse reactions were recorded. RESULTS The total effective rate （87.30%） of the observation group was significantly higher than that of the control group （71.43%） （P＜0.05）. NIHSS scores of the two groups at 1st， 7th and 14th day after treatment， the mRS score at 90th day after treatment， and the platelet aggregation rate， whole blood viscosity， plasma viscosity and fibrinogen at 14th day after treatment were significantly lower than those before treatment in the same group， and the observation group was significantly lower than the control group at the same period （P＜0.05）. The total incidences of adverse reactions such as nausea， headache， fever， gastrointestinal bleeding， oral and nasal mucosal bleeding and thrombocytopenia in both groups of patients were 28.57% respectively， with no statistically significant difference （P＞0.05）. CONCLUSIONS For patients with early neurological deterioration in acute ischemic stroke， the addition of tirofiban can accelerate the recovery of neurological function， improve blood hyperviscosity and platelet aggregation， and improve the prognosis of patients with good safety.

Objective:This study aimed to reveal the distribution and course of the branches of the infraorbital nerve(IN),its communication relationship between the branches of the infraorbital nerve and facial nerve,so as to provide morphological basis for clinical implementation of accurate infraorbital nerve trunk in the infraorbital canal,regional facial anesthesia and facial surgery,so as to improve the success rate of maxillofacial surgery.Methods:25 adult cada-vers with formalin immobilized semi-face were selected.Exclude facial defect samples caused by tumor,trauma,deformity,surgery,etc.The length and diameter of the trunk of the infraorbital nerve and the length of the infraorbital canal were measured.The total number of infraorbital nerve and the number of branches were counted,and the course,distribution and communication relationship between infraorbital nerve and facial nerve were investigated.Results:The length of infraorbital nerve trunk ranged from 19.61 to 44.47 mm,with an average length of(23.33±4.95)mm.The length of infraorbital canal ranged from 9.49 to 31.21 mm,with an average length of(12.87±3.99)mm.The number of infraorbital nerve branches ranged from 5 to 12,and the average number was(7.29±2.29).The number of upper labial branches was the widest,ranging from 1 to 5,while the distribution area of eyelid branches was the narrowest.There are(were)a large number of intersections and anastomoses between the infraorbital nerve and the facial nerve,forming a complex multi-layer network structure.Conclusion:The infraorbital nerve trunk and the infraorbital canal va-ry in length.The number and distribution range of infraorbital nerve branches are not constant,and the communication relationship between infraorbital nerve and facial nerve is complicated.

Objective To investigate the effect of Zhuang medicated thread moxibustion on postherpetic neuralgia model rats,and to verify the mechanism of Th1/Th2/Th17 cytokine balance regulation in central nervous system.Methods 50 SD rats were randomly divided into blank group,model group,thread-moxibustion without drugs group,Zhuang medicated thread moxibustion group and pregabalin group,with 10 rats in each group.Except for blank group,the rat model of postherpetic neuralgia was induced by a single intrapitoneal injection of resin-toxin(RTX).After successful modeling,each group was given corresponding treatment for 21 days.The Mechanical Pain Threshold(PWT)and Thermal withdrawal latency(TWL)were detected 3 days before modeling,1,4 and 7 days after modeling,and 3,7,14 and 21 days after intervention.After the intervention,extract spinal cord tissue,Flow cytometry was used to detect changes in the proportion of Th1/Th2/Th17 cells;The mRNA expression levels of IFN-γ,IL-2,IL-4,IL-10,IL-17 and IL-22 were detected by qPCR;The positive expressions of IFN-γ,IL-2,IL-4,IL-10,IL-17 and IL-22 were observed by immunohistochemistry.The protein expressions of IFN-γ,IL-2,IL-4,IL-10,IL-17 and IL-22 were detected by Western blot to elucidate the regulation effect of this therapy on the equilibrium mechanism.Results After intrapitoneal injection of resin-toxin,the PWT of rats showed a downward trend,while the TWL showed an upward trend,showing the separation of heat and pain,which was consistent with the clinical manifestations of PHN.After Zhuang medicated thread moxibustion therapy,PWT increased and TWL decreased in PHN rats,which reduced the separation trend of heat and pain.Thread-moxibustion without drugs group,Zhuang medicated thread moxibustion group and pregabalin group can promote Th1 response in the central nervous system(spinal cord),increase the proportion of CD4+IL-2+cells and the contents of IFN-γ and IL-2 in the spinal cord tissue,and up-regulate the expression of IFN-γ and IL-2 mRNA and protein.Meanwhile,Th2 and Th17 responses in the central nervous system were inhibited,and the proportions of CD4+IL-4+and CD4+IL-17A+cells and the contents of IL-4,IL-10,IL-17 and IL-22 in the spinal cord tissue were reduced.The mRNA and protein expressions of IL-4,IL-10,IL-17 and IL-22 were down-regulated.In addition,Zhuang medicated thread moxibustion group and pregabalin group had similar efficacy in correcting Th1/Th2/Th17 lymphocyte imbalance in the central nervous system,and both were better than the Thread-moxibustion without drugs group.Conclusion Zhuang medicated thread moxibustion can improve the separation trend of heat and pain in postherpetic neuralgia rats,which may be achieved by regulating Th1/Th2/Th17 cell balance and related cytokine levels.

Objective To explore the influence of longitudinal and oblique hollow lag screw internal fixation on interphalangeal range of motion,metacarpal range of motion and complications in patients with transverse fractures of proximal phalanges.Methods Retrospective analysis was performed on 102 patients with transverse fractures of proximal phalanges admitted to department of orthopedics of our hospital from June 2021 to February 2022.According to treatment methods,the patients were divided into longitudinal group and oblique group.The longitudinal group was given longitudinal hollow lag screw internal fixation while the oblique group was treated with oblique hollow lag screw internal fixation.The baseline data of the enrolled subjects were excluded from the influence of confounding factors according to the propensity matching scoring method(caliper value=0.02),and 51 patients with comparable baseline data were obtained in each group.The surgical status(surgical time and healing time),ranges of motions of interphalangeal and metacarpal joints,excellent and good rate of hand function(total active movement,TAM)and complications at 18 months after surgery were compared between the two groups.Results All patients successfully completed the surgery,and at least 18 months of follow-up data were obtained.There was no statistical significance in the surgical time or follow-up time between the two groups(P＞0.05).The healing time in oblique group(6.57±1.22)weeks,was significantly shorter than that in longitudinal group(7.82±1.54)weeks(P＜0.05).At 18 months after surgery,the interphalangeal range of motion was significantly higher in oblique group(82.62±3.41)° than that in longitudinal group(77.45±7.46)°(P＜0.05),but there was no statistical difference in metacarpal range of motion between the two groups(P＞0.05).The excellent and good rate of hand function in oblique group(94.12％)at 18 months after surgery was significantly higher than that in longitudinal group(80.39％)(P＜0.05).The incidence of complications revealed no statistical significance between oblique group(1.96％)and longitudinal group(3.92％)(P＞0.05).Conclusion In the hollow lag internal screw fixation treatment of patients with transverse fractures of proximal phalanges,both longitudinal and oblique screw methods have good effects,but the oblique screw method is more beneficial to the recovery of hand function.

OBJECTIVE: Because of the limited number of studies and small sample sizes, whether metabolic syndrome (MS) leads to the occurrence and progression of osteoporosis and the possible underlying mechanisms require further investigation. This study aimed to investigate the association between MS and osteoporosis, along with its influencing factors. METHODS: This observational cross-sectional study included 139,470 individuals aged ≥ 18 years who underwent health examinations from September 2014 to March 2022. Based on bone mineral density (BMD) screening results, the participants were categorized into a suspected osteoporosis or non-osteoporosis group (control). Participants were further divided into those who met 0 MS criteria, 1 MS criterion, 2 MS criteria, and ≥ 3 MS criteria (MS group). Participants who had undergone health examinations at least twice formed the follow-up cohort; a self-matched analysis was performed on those with follow-up periods ≥ 5 years and unchanged MS grouping. RESULTS: Several examination indicators in the suspected osteoporosis group showed statistically significant differences compared with the control group. The proportion of suspected osteoporosis in the MS group was significantly increased compared with that in the 0 MS criteria group (odds ratio [ OR]: 1.215, Z = 29.11, P < 0.001, 95% confidence interval: 1.199-1.231). After adjusting for age, sex, smoking, and alcohol consumption, the 2 MS criteria group and MS group still had OR values > 1 ( P < 0.001). In the follow-up cohort, the proportion of suspected osteoporosis increased gradually with an increase in the number of MS criteria met at baseline and during each follow-up visit ( P < 0.05), with the highest proportion observed in the MS group. However, the proportion of suspected osteoporosis did not increase significantly over time in the different MS groups ( P > 0.05). In the follow-up cohort, the proportion of individuals transitioning from normal BMD to suspected osteoporosis was higher in the MS group after ≥ 5 years of follow-up compared with the group meeting 0 MS criteria (0.08% versus 1.15%, χ ² = 10.76, P = 0.001). There was no significant difference in BMD values for the 0 MS criteria group after 5 years ( P > 0.05), whereas the other three groups experienced a significant decrease in BMD values after 5 years ( P < 0.05). CONCLUSION MS is an independent risk factor for osteoporosis, and the effect of risk factors related to MS on osteoporosis may exceed that of aging alone. The specific mechanisms warrant further investigation.

Objective:To evaluate the effect of pre-injection of young rat plasma on cognitive dysfunction after cerebral ischemia-reperfusion (I/R) in aged rats and the role of phosphatidylinositol 3-kinase/serine threonine protein kinase (PI3K/Akt) signaling pathway.Methods:Seventy-two SPF-grade healthy male Sprague-Dawley rats, aged 18 months, weighing 600-650 g, were divided into 4 groups ( n=18 each) by the random number table method: control group (group C), cerebral I/R group (group IR), pre-injection of young rat plasma group (group P) and PI3K inhibitor LY294002 group (group LY). In group P and group LY, young rat plasma 100 μl/time was injected via the tail vein. In group C and group IR, the equal volume of normal saline was injected via the the tail vein, 2 times a week for 4 weeks. Then the model of cerebral I/R injury was developed under sevoflurane anesthesia in IR, P and LY groups. LY294002 0.3 mg/kg was injected through the tail vein at 1 h before anesthesia in LY group. The neurological deficit score (Longa score) was performed at 24 h after reperfusion, and then 6 rats were randomly sacrificed, and brain tissues were obtained to determine the cerebral infarct volume. Spontaneous mobility and anxiety-like behavior were assessed by the open field test at day 29 of reperfusion, and cognitive function was assessed by the novel object recognition test at day 30 of reperfusion. At the end of the behavioral test, rats were sacrificed, hippocampal tissues were isolated for determination of the expression of phosphorylated PI3K (p-PI3K), phosphorylated Akt (p-Akt), postsynaptic dense protein-95 (PSD-95) and synaptic vesicle protein (SYN) (by Western blot), and the dendritic length and dendritic spine density of neurons in the hippocampal CA1 region. Results:There was no significant difference in motor speed, distance traveled, and time of staying at the center of the open field among the four groups ( P>0.05). Compared with group C, the Longa score and cerebral infarct volume were significantly increased, the percentage of novel object exploration and discrimination index were decreased, the expression of p-PI3K, p-Akt, PSD-95 and SYN in hippocampal tissues was down-regulated, and the dendritic length and dendritic spine density of hippocampal neurons were decreased in IR, P and LY groups ( P<0.05). Compared with group IR, Longa score and cerebral infarct volume were significantly decreased, the percentage of novel object exploration and discrimination index were increased, the expression of p-PI3K, p-Akt, PSD-95 and SYN in hippocampal tissues was up-regulated, and the dendritic length and dendritic spine density of hippocampal neurons were increased in group P ( P<0.05), and no significant change was found in the parameters mentioned above in group LY ( P>0.05). Compared with group P, Longa score and cerebral infarct volume were significantly increased, the percentage of novel object exploration and discrimination index were decreased, the expression of p-PI3K, p-Akt, PSD-95 and SYN in hippocampal tissues was down-regulated, and the dendritic length and dendritic spine density of hippocampal neurons were decreased in group LY ( P<0.05). Conclusions:Pre-injection of young rat plasma can attenuate cognitive dysfunction after cerebral I/R in aged rats, and the mechanism is related to activation of hippocampal PI3K/Akt signaling pathway and improvement in synaptic plasticity.
