		                        			Neuropathic pain is a chronic pain condition caused by damage or dysfunction of the nervous sys-tem.Symptoms of neuropathic pain include spontaneous pain,hyperalgesia,and sensory abnormalities.AMP-activated protein kinase(AMPK)is a key energy regulator that maintains cellular homeostasis by modulating carbohydrate and lipid metabolism.Recent studies have highlighted its role in synaptic plasticity and glial cell function,suggesting that AMPK signaling pathways contribute to the onset and progression of neurological disorders.Investigations using animal models of neuropathic pain as well as clinical research have illustrated aberrations in AMPK expression and activity at various sites along sensory conduction pathways.Treatment with AMPK agonists has been shown to alleviate pain symptoms,suggesting that dysregulation of AMPK expression/function contributes to the development and persistence of neuropathic pain.There-fore,the development of analgesics targeting AMPK has garnered considerable attention worldwide.This article provides a comprehensive review of the mechanisms by which AMPK participates in neuropathic pain,with the aim of guiding the de-velopment of related analgesic drugs.

		                        			To investigate the influencing factors of depressive symptoms among rural elderly patients with chronic diseases in China, so as to provide insights into depression prevention and control among the rural elderly patients with chronic diseases.
		                        		
		                        			Methods:
		                        			The basic demographics, health status, and lifestyle of rural residents at ages of 65 years and older who had at least one chronic disease were retrieved from The Chinese Longitudinal Healthy Longevity Survey (CLHLS) database in 2018, and participants' depressive symptoms were assessed with The Center for Epidemiological Studies Depression-10 (CES-D-10) scale. Factors affecting the depressive symptoms were identified with a multivariable logistic regression model. 
		                        		
		                        			Results:
		                        			Totally 5 146 rural elderly patients with chronic diseases were enrolled, including 2 373 men (46.11%) and 2 773 women (53.89%). The prevalence of depressive symptoms was 27.13%. Multivariable logistic regression analysis identified having two and more children (OR=0.614, 95%CI: 0.387-0.975), living alone (OR=1.450, 95%CI: 1.192-1.764), life satisfaction (general, OR=1.933, 95%CI: 1.651-2.264; low, OR=5.366, 95%CI: 3.488-8.254), self-assessed health status (general, OR=2.697, 95%CI: 2.284-3.185; poor, OR=5.338, 95%CI: 4.262-6.685), disability in instrumental activities of daily living (OR=1.592, 95%CI: 1.328-1.908), sleep duration (normal, OR=0.502, 95%CI: 0.429-0.586; too long, OR=0.494, 95%CI: 0.405-0.603), exercise (OR=0.721, 95%CI: 0.607-0.856), watching TV (OR=0.787, 95%CI: 0.664-0.933), and gardening activities (OR=0.781, 95%CI: 0.626-0.975) as factors affecting depressive symptoms among rural elderly patients with chronic diseases.
		                        		
		                        			Conclusions
		                        			The prevalence of depressive symptoms was 27.13% among rural elderly patients with chronic diseases.

		                        			ObjectiveTo determine whether HBV DNA polymerase is associated with T-cell failure and thus mediates the immune escape of HBV-related hepatocellular carcinoma (HCC) tumor cells, and to investigate the specific molecular mechanisms. MethodsLiver cancer cell lines Huh7 and HepG2 stably transfected with HBV DNA polymerase expression plasmid with Flag (Flag-HBV-P) and intercellular adhesion molecule-1 (ICAM1) were co-cultured with Jurkat cells, and MTT assay, qRT-PCR, and ELISA were used to measure Jurkat cell proliferation, activation (CD69 expression), and secretion of the cytokine IFN-γ. RNA-seq was used to screen for differentially expressed immune-associated molecules between stably transfected cell lines and control cells, and mRNA half-life and protein half-life assays were used to determine the specific levels of the immune-associated molecules that were affected by HBV DNA polymerase. Related websites were used to predict the transcription factors that may bind to the promoter region of this immune-associated molecule, Western blot was used to verify the effect of transcription factors on the immune-associated molecule, and rescue experiment was used to determine whether HBV DNA polymerase affects the expression level of the immune-associated molecule through this transcription factor. The independent-samples t test was used for comparison between two groups. ResultsThe experimental group had significant reductions in Jurkat cell proliferation, activation, and cytokine secretion compared with the control group (all P<0.01). Compared with the control group, the experimental group (Huh7 and HepG2 cell lines) had significant reductions in the mRNA and protein expression levels of ICAM1 (all P<0.01). Website prediction identified the ICAM1 promoter and preliminarily highlighted NFKB1, RELA, and STAT3. Compared with the control group, the experimental group (Huh7 and HepG2 cell lines) had a significant reduction in the protein expression level of p65 (all P<0.01). After p65 overexpression, there was a significant increase in the protein expression level of ICAM1, and after the expression of p65 was reduced, there was a significant reduction in the protein expression level of ICAM1 (all P<0.01). In the rescue experiment, there was no significant difference in the protein expression level of ICAM1 between the control group and the experimental group after p65 overexpression (all P>0.05). After the overexpression of ICAM1, there were no significant differences in the proliferation, activation, and cytokine secretion of Jurkat cells between the control group and the experimental group (Huh7 and HepG2 cell lines) (all P>0.05). ConclusionHBV DNA polymerase downregulates the level of ICAM1 to mediate HCC immune escape by inhibiting the expression of p65 in NF-κB.

		                        			Objective:To investigate the application value of domestic robotic surgical system in radical resection of hilar cholangiocarcinoma (hCCA).Methods:The retrospective and descriptive study was constructed. The clinicopathological data of a 66-year-old male patient with hCCA who was admitted to the Second Hospital of Shandong University in November 2022 were collected. Radical resection of hCCA was performed using the Toumai? laparoscopic surgical robot system. Observation indicators: (1) intraoperative conditions; (2) postoperative conditions; (3) follow-up. Count data were represented as absolute numbers and (or) percentages.Results:(1) Intraoperative conditions. The patient underwent radical resection of hCCA successfully using robotic surgical system, including tumor resection, lymph node dissection, and gastrointestinal reconstruc-tion. The operation time and volume of intraoperative blood loss were 400 minutes and 100 mL, respectively, and no intraoperative blood transfusion was required. (2) Postoperative conditions. The patient began ambulation on postoperative day 1 and began taking liquid food on postoperative day 4. Liver function examination and abdominal computed tomograph (CT) on postoperative day 5 showed a decrease in serum bilirubin, no biliary or intestinal leakage, and no edema or necrosis at the anastomotic site. The abdominal pre-anastomotic and post-anastomotic drainage tubes were removed on the 7th and 9th day after the surgery respectively, and the patient was discharged on the 10th day after surgery. Results of postoperative pathological examination showed moderately to poorly differentiated adenocarcinoma of the bile duct. Immunostaining was positive for CK7 and CK19. The Ki-67 proliferation index was 35%. The proximal and distal resection margin of bile duct were negative. The tumor diameter was 30 mm. Perineural invasion was positive. The surgical specimen margin was negative. Two lymph nodes were identified containing tumor cells positive for malignancy. No tumor cell metastasis was detected in the No.8, No.12 or gastric lesser curvature lymph nodes submitted for pathological examination. (3) Follow-up. The patient was followed up at postoperative 1-, 3-, 5-month after discharge. During follow-up period, results of liver function examination and abdominal CT showed liver function restore to normal levels, no complication such as biliary fistula, intestinal fistula, gastroparesis or tumor metastasis.Conclusion:The Domestic Toumai ? laparoscopic surgical robot system can be applied to radical resection of hCCA.

		                        			Objective:To evaluate the clinical efficacy of acupuncture combined with extracorporeal shock wave therapy in the treatment of piriformis syndrome.Methods:Eighty patients with piriformis syndrome who received treatment in Huaihe Energy Occupational Disease Prevention Hospital Rehabilitation Medicine Center from February 2021 to December 2022 were included in this study. They were divided into a treatment group ( n = 40) and a control group ( n = 40) according to different treatment methods using a retrospective cohort study design. The treatment group was treated with acupuncture combined with extracorporeal shock wave therapy, once every 7 days for 3 consecutive weeks. The control group was treated with extracorporeal shock wave therapy alone once every 7 days for 3 consecutive weeks.Pre- and post-treatment visual analogue scale scores and clinical efficacy were compared between the two groups. Results:There was no significant difference in baseline data between the two groups (all P > 0.05). After treatment, the visual analogue scale score decreased in each group. After adjusting for covariates, there was no significant difference in visual analogue scale score between the two groups ( F = 112.38, P < 0.001). After adjusting the pre-treatment visual analogue scale score, the post-treatment visual analogue scale score in the treatment group was lower than that in the control group [1.417 (95% CI: 1.151-1.683)]. The total response rate in the treatment group was 97.5% (39/40), which was significantly higher than 82.5% (33/40) in the control group ( Z = -2.03, P = 0.042). Conclusion:Acupuncture combined with extracorporeal shock wave therapy is highly effective on piriformis syndrome.

		                        			Despite the advancement of treatments, adults with relapsed/refractory (R/R) B-lineage acute lymphoblastic leukemia (B-ALL) have poor prognosis, with an expected five-year overall survival (OS) rate of 10%‒20% (Nguyen et al., 2008; Oriol et al., 2010). Extramedullary relapse of B-ALL is regarded as a high-risk factor generally associated with poor survival, occurring in about 15% to 20% of all relapsed patients (Ding et al., 2017; Sun et al., 2018). The central nervous system (CNS) and the testes are the most common sites of extramedullary relapse of B-ALL. In addition, extramedullary leukemia can appear in the skin, eyes, breasts, bones, muscles, and abdominal organs. The prognosis of relapsed extramedullary B-ALL after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is extremely poor (Spyridonidis et al., 2012; Dahlberg et al., 2019). Conventional chemotherapy or radiation is often ineffective in such patients. At present, there are no optimal treatment strategies for treating extramedullary leukemia after allo-HSCT.

		                        			Objective:To compare the differences of short and long-term outcomes between laparoscopic surgery and open surgery treatment of intrahepatic cholangiocarcinoma patients.Methods:A retrospective cohort study was conducted to collect the clinical data of 118 patients with intrahepatic cholangiocarcinoma who underwent surgery in Qilu Hospital of Shandong University from January 2015 to June 2020. They were divided into laparoscopy group and open group according to the operation methods. The perioperative data, such as intraoperative surgical conditions, hospital costs, postoperative complications, postoperative blood biochemical tests, and the follow-up data of the two groups were compared.Results:In the laparoscopic group, there were 40 patients, 18 males and 22 females, aged (61.5±9.1) years. There were 78 patients in the open group, 48 males and 30 females, aged (61.2±8.3) years. The tumor size of the laparoscopic group was (4.4±1.8) cm, which was smaller than that of the open group (6.0±3.3) cm, and the differences were statistically significant ( P<0.05). In the laparoscopic group, 4 cases (10%) were converted to open surgery. The intraoperative blood loss, intraoperative blood transfusion proportion, 3 or more liver segments resection proportion and hospital costs of laparoscopic group were lower than those of open group [200.0(100.0, 261.8) ml vs. 300.0(100.0, 400.0) ml, 5.0%(2/40) vs. 26.9%(21/78), 37.5%(15/40) vs. 66.7%(52/78), (6.2±2.0) wan yuan vs. (7.2±2.3) wan yuan], the differences were statistically significant (all P<0.05). There were no significant differences in the incidence of postoperative complications between the two groups ( P>0.05). On the first post-operative day, ALT serum level and the third post-operative day TBil serum level in the laparoscopic group were lower than those in the open group [188.5(130.5, 274.0) U/L vs. 320.0(144.0, 427.0) U/L, 26.4(18.3, 26.4) μmol/L vs. 31.6(18.8, 37.5) μmol/l], the differences were statistically significant ( P<0.05). There were no significant differences in 1-year and 2-year overall survival rate and disease-free survival rate between the two groups ( P>0.05). Conclusion:Compared with open surgery, laparoscopic surgery in the treatment of intrahepatic cholangiocarcinoma has better short-term outcomes, and can achieve similar results in medium- or long-term outcomes.

		                        			Objective:To analyze the epidemiological and clinical characteristics of imported COVID-19 cases after SARS-CoV-2 vaccination and to provide evidence for the prevention and control of COVID-19.Methods:The imported COVID-19 cases in Chengdu as of April 15, 2021 were divided into the vaccinated group and unvaccinated group according to the history of SARS-CoV-2 vaccination. The epidemiological and clinical data of the cases were collected retrospectively, and the differences in epidemiological and clinical characteristics of the two groups were compared. Laboratory tests consisted of nucleic acid test, clinical index test, serum antibody test and lymphocyte test. Software WPS2019 was used for data management and software R 4.0.3 was used for statistical analysis.Results:A total of 75 COVID-19 cases were included in the analysis, in which 20 had received SARS-CoV-2 vaccination and only 4 with clinical symptoms, 55 patients did not receive SARS-CoV-2 vaccination, and 16 had clinical symptoms. In vaccinated group, the first injection time of vaccination ranged from July to November 2020, and 10 cases received two doses of vaccine simultaneously and 10 cases received two doses of vaccine at intervals of 14-57 days. The intervals between the completion of vaccination and the onset ranged from 87 days to 224 days. The differences in classification and clinical type between the two groups were significant. Significant differences were observed in case classification and clinical type between vaccinated group and unvaccinated group ( P<0.05). The vaccinated group had a relatively high proportion of asymptomatic infections (40.00%, 8/20), while mild infections were mainly observed in the unvaccinated group(76.36%,42/55). The differences in Ct values (ORF1ab gene and N gene) at the diagnosis were not significant between vaccinated group and unvaccinated group ( P>0.05), similar results were also observed in lymphocyte subtypes, procalcitonin and C-reactive protein level comparisons. Serum amyloid A level was higher in unvaccinated group than in vaccinated group ( P<0.05). However, the SARS-CoV-2 related serum antibody of IgM, IgG and total antibody levels were significantly higher in vaccinated group ( P<0.05). Conclusions:Risk of infection still exists with SARS-CoV-2 after vaccination, which can facilitate the production of specific serum antibody of IgM and IgG when people are exposed to the virus. It has a certain protective effect on SARS-CoV-2 infected persons. Vaccination can reduce the clinical symptoms and mitigate disease severity.

		                        			Objective:To explore the risk factors of acute renal injury (AKI) in exertional heat radiation disease (EHS) .Methods:In november 2019, the clinical data of 69 EHS patients admitted from July 2015 to September 2019 were reviewed. The general data, laboratory indexes, Glasgow score (GCS) at admission, 24-hour acute physiology and chronic health score Ⅱ (APACHE Ⅱ) , exposure time rate and physical labor intensity were collected. According to the occurrence of AKI, the patients were divided into AKI group and non-AKI group, 31 and 38 in each group. The differences of general data and laboratory indexes between the two groups were compared, and the t and Mann-Whitney U test were used to compare the two groups. The enumeration data are expressed by examples and constituent ratio (%) . Independent sample χ 2 test is used for inter-group comparison, and multiple test is used for multi-sample comparison. The correlation was analyzed by linear regression. Risk factors were analyzed by Logistic regression analysis. Results:At discharge, 31 of 69 EHS patients developed AKI. Compared with the non-AKI group, the heart rate, white blood cell count, lactic acid, D-dimer and myoglobin were higher; MAP, platelet count and PH were lower in the AKI group. The difference was statistically significant ( P<0.05) . APACHE Ⅱ score, core temperature, time to drop to 38.5 ℃, contact time rate, platelet count, pH, lactic acid, D-dimer and myoglobin were all correlated with creatinine ( r=0.57, 0.42, 0.80, 0.78, 0.57, 0.43, 0.51, 0.55, 0.79) . APACHE Ⅱ score, time to drop to 38.5C, Lac and MYO are the risk factors of AKI in EHS patients. Multivariate Logistic regression analysis showed that the time required to drop to 38.5C was an independent risk factor for the occurrence of AKI. Conclusion:AKI is a serious complication of EHS. EHS complicated with AKI, should be identified early and effective intervention measures should be taken.

		                        			Objective:To explore the risk factors of acute renal injury (AKI) in exertional heat radiation disease (EHS) .Methods:In november 2019, the clinical data of 69 EHS patients admitted from July 2015 to September 2019 were reviewed. The general data, laboratory indexes, Glasgow score (GCS) at admission, 24-hour acute physiology and chronic health score Ⅱ (APACHE Ⅱ) , exposure time rate and physical labor intensity were collected. According to the occurrence of AKI, the patients were divided into AKI group and non-AKI group, 31 and 38 in each group. The differences of general data and laboratory indexes between the two groups were compared, and the t and Mann-Whitney U test were used to compare the two groups. The enumeration data are expressed by examples and constituent ratio (%) . Independent sample χ 2 test is used for inter-group comparison, and multiple test is used for multi-sample comparison. The correlation was analyzed by linear regression. Risk factors were analyzed by Logistic regression analysis. Results:At discharge, 31 of 69 EHS patients developed AKI. Compared with the non-AKI group, the heart rate, white blood cell count, lactic acid, D-dimer and myoglobin were higher; MAP, platelet count and PH were lower in the AKI group. The difference was statistically significant ( P<0.05) . APACHE Ⅱ score, core temperature, time to drop to 38.5 ℃, contact time rate, platelet count, pH, lactic acid, D-dimer and myoglobin were all correlated with creatinine ( r=0.57, 0.42, 0.80, 0.78, 0.57, 0.43, 0.51, 0.55, 0.79) . APACHE Ⅱ score, time to drop to 38.5C, Lac and MYO are the risk factors of AKI in EHS patients. Multivariate Logistic regression analysis showed that the time required to drop to 38.5C was an independent risk factor for the occurrence of AKI. Conclusion:AKI is a serious complication of EHS. EHS complicated with AKI, should be identified early and effective intervention measures should be taken.
