OBJECTIVE To study the mechanism of Compound lizard powder on reversing cisplatin（DDP） resistance in resistant gastric cancer cell MKN45/DDP through nuclear factor-κB （NF-κB）/SNAIL signaling pathway. METHODS MKN45/DDP cells were divided into model group （20% normal rat serum）， DDP group （1.3 μg/mL DDP+20% fetal bovine serum） and Compound lizard powder low- and high-dose drug-containing serum+DDP groups （17.2， 68.8 g/kg Compound lizard powder 20% drug-containing serum+1.3 μg/mL DDP）. The viability， apoptosis and intracellular autophagosome of MKN45/DDP cells were detected. The content of microtubule-associated protein 1 light chain 3 （LC3） in the cell supernatant was detected. The expressions of B-cell lymphoma 2 （Bcl-2）， Bcl-2-related X protein （Bax）， as well as the protein expression levels of phosphorylated NF-κB p65 （p-NF-κB p65） and SNAIL were detected. The molecular mechanism of Compound lizard powder in improving DDP resistance was further clarified by using NF-κB pathway agonist tumor necrosis factor-α （TNF-α）. RESULTS Compared with model group and DDP group， the cell survival rates of Compound lizard powder low- and high-dose drug-containing serum+DDP groups were significantly decreased （P＜0.05）， while the levels of apoptosis and autophagic death were significantly increased （P＜0.05）. The expression levels of Bcl-2 （except for the compound lizard powder low-dose drug-containing serum+DDP group）， p-NF-κB p65 and SNAIL protein in MKN45/DDP cells were significantly decreased （P＜0.05）. The content of LC3 and expression of Bax protein were significantly increased （P＜0.05）. High-dose Compound lizard powder drug-containing serum+DDP could effectively reverse the down-regulation of LC3 Ⅱ/LC3 Ⅰ and Bax protein expression induced by TNF- α （P＜0.05）. CONCLUSIONS Compound lizard powder drug-containing serum combined with DDP can induce apoptosis and autophagic death of MKN45/DDP cells by inhibiting NF-κB/SNAIL signaling pathway， thus reversing DDP resistance of cells.

Prone position ventilation (PPV) is an important protective strategy for lung ventilation, widely used in clinical practice, especially since the novel coronavirus infection pandemic. Since PPV is a non-physiological position, improper implementation and management can lead to serious adverse events such as pressure injury, facial edema, unplanned extubation and (or) reintubation, and even asphyxia. At present, preventive and protective strategies are mainly used to manage PPV-related complications in clinical practice. These strategies not only increase the workload of medical staff and the use of consumables, but also increase the medical cost of patients, further burdening patients and their families economically. To overcome the above problems, the medical staff of the department of critical care medicine of Tianjin Third Central Hospital designed a prone position head auxiliary support device and obtained a national utility model patent (patent number: ZL 2022 2 1751906.3). The device consists of annular plate, folding plate, support frame, reflector and wheel bodies. It serves to reduce pressure on the head and facial skin, while also exposing the mouth, nose, eyes, and ears to the hollow position of the annular plate according to the patient's position. At the same time, the patient's face or side skin can be observed through the lower reflector. The height of the annular plate was adjusted by adjusting the support frame, and the head was raised to reduce facial edema. The setting of strip groove, through hole and hook can sort out the facial pipeline, keep the drainage unobstructed, prevent catheter displacement and unplanned extubation, and has certain clinical promotion and practical value.

Background and aims:Early and accurate diagnosis of the coexistence of Wilson's disease(WD)and chronic hepatitis B(CHB)presents a significant challenge for clinicians.The objective of this study was to retrospectively analyse the characteristics of such patients to improve clinical practice and provide a reference for clinical management.Methods:From January 2011 to December 2022,35 patients with concurrent CHB and WD(CHB+WD group)were identified.A total of 127 patients with CHB(CHB group)and 168 patients with WD(WD group)were included in the control group between January 2016 and December 2021.Propensity score matching(PSM)was performed to balance the baseline values between groups.The Kaplan-Meier(K-M)survival analysis and log-rank test were performed to compare the prognoses.Results:In the cohort of 35 patients with concurrent CHB and WD,74.3％of patients(26 patients)faced a substantial delay of up to 10 years(range:0-40 years)in WD diagnosis following their CHB diagnosis.Twenty-three(65.7％)patients had cirrhosis at the time of WD diagnosis,and 26(74.3％)patients experienced liver failure.The levels of serum copper and uric acid were lower in patients in the CHB+WD group than in those in the CHB group.Patients in the CHB+WD group presented higher alanine transaminase and total bile acid levels compared to those in the WD group.K-M survival analysis indicated that patients with CHB and WD had poorer outcomes than those with CHB alone;however,the outcomes were similar to those of individuals with WD alone.The optimal cut-point of serum ceruloplasmin(CP)in identifying WD in CHB patients was 0.10 g/L before PSM and after PSM.Conclusions:The present study emphasizes the importance of clinicians being vigilant for concurrent CHB and WD diagnoses,as delays in WD diagnosis may adversely affect patient outcomes.CHB patients with serum CP below 0.10 g/L are highly recommended to screen for WD.

Objective To investigate the relationships of cerebrospinal fluid levels of collagen triple helix repeat containing-1(CTHRC1)and olfactomedin-3(OLFM3)with cognitive impairment and cere-brospinal fluid biomarker levels in patients with Alzheimer's disease(AD).Methods Ninety-six patients with AD were selected as study objects(AD group),and divided into mild group(n=34),moderate group(n=39)and severe group(n=33)according to Clinical Deentia Scale(CDR)score.Sixty patients without cognitive impairment who underwent lumbar puncture during the same period served as the control group.Enzyme-linked immunosorbent assays were used to measure cere-brospinal fluid levels of CTHRC1,OLFM3 and biomarkers[β-amyloid(Aβ)-40,Aβ-42,Aβ42/Aβ-40,total tau(T-tau)and phosphorylated tau(P-tau)].Cognitive impairment in AD patients was as-sessed using the Mini-Mental State Examination(MMSE)and Montreal Cognitive Assessment(MoCA).The relationships of CSF CTHRC1 and OLFM3 levels with cognitive impairment and cerebrospinal flu-id biomarkers were analyzed.Results The AD group showed significantly higher cerebrospinal fluid levels of CTHRC1,T-tau and P-tau,and significantly lower levels of OLFM3,Aβ-42 and Aβ42/Aβ-40 compared to the control group(P＜0.05).The area under the curve(AUC)for diagnosing AD with cerebrospinal fluid CTHRC1 and OLFM3 was 0.839 and 0.822,respectively,and the com-bined AUC was 0.923.Cerebrospinal fluid CTHRC1 of mild group,moderate group and severe group were increased successively,and OLFM3 was decreased successively,the difference was sta-tistically significant(P＜0.05).Cerebrospinal fluid Aβ-42 and Aβ-42/Aβ-40 in mild,moderate and severe groups were decreased successively,while T-tau and P-tau were increased successively,with statistical significance(P＜0.05).The MMSE and MoCA scores of mild group,moderate group and severe group decreased successively,and the difference was statistically significant(P＜0.05).Cerebrospinal fluid CTHRC1 levels were positively correlated with disease severity,while OLFM3 levels were negatively correlated(P＜0.05).Cerebrospinal fluid CTHRC1 was negatively correlated with Aβ42,Aβ42/Aβ-40,MMSE scores and MoCA scores,and positively correlated with T-tau and P-tau(P＜0.05).Cerebrospinal fluid OLFM3 was positively correlated with Aβ-42,Aβ42/Aβ-40,MMSE scores and MoCA scores,and negatively correlated with T-tau and P-tau(P＜0.05).Conclusion In the cerebrospinal fluid of patients with AD,CTHRC1 is elevated while OLFM3 is decreased.Both CTHRC1 and OLFM3 are associated with the severity of AD,cog-nitive impairment and levels of cerebrospinal fluid biomarkers.

OBJECTIVE To explore the mechanism of Compound lizard powder reducing cisplatin resistance in gastric cancer by regulating glycolytic activity based on phosphoinositide 3-kinase（PI3K）/protein kinase B（Akt） signaling pathway. METHODS Human gastric cancer MKN45 and MKN45/DDP （cisplatin-resistant） cells were cultured in vitro and intervened with different mass concentrations of cisplatin （0.1， 0.2， 0.4， 0.8， 1.6， 3.2 μg/mL） to detect the survival rate， half inhibitory concentration （IC50） and drug resistance index. MKN45/DDP cells were inoculated subcutaneously in the right anterior axilla of nude mice to prepare a transplanted tumor model of gastric cancer. After successful modeling， they were randomly divided into model group， cisplatin group （0.002 g/kg）， Compound lizard powder group （2.8 g/kg） and combination group （the same dose as each single drug group）， with 8 nude mice in each group. Each administration group was given relevant solution， twice a week （cisplatin， i.p.） or twice a day （Compound lizard powder， i. g.）， for 4 consecutive weeks. During the experiment， the body weight of nude mice was monitored， and tumor volume and inhibitory rate of tumor were calculated. The levels of inflammatory factors （tumor necrosis factor- α， interleukin-6） in tumor tissue， the mRNA and protein expressions of multidrug resistance-associated protein 1 （MRP1）， P-glycoprotein （P-gp）， glucose transporter-1 （GLUT1） and lactate dehydrogenase A （LDHA）， as well as the protein expressions of PI3K， phosphorylated PI3K （p-PI3K）， Akt， phosphorylated Akt （p-Akt）， hexokinase-2 （HK2） and pyruvate kinase M2 （PKM2） were all detected. RESULTS With the intervention of different concentrations of cisplatin， the survival rate of MKN45/DDP-resistant cells was significantly higher than that of MKN45 parent cells （P＜0.05）. IC50 value of MKN45/DDP and MKN45 cells were（1.052 0±0.221 9） and （0.372 1±0.238 0）μg/mL， and the drug resistant index was 2.827. Compared with the model group， cisplatin group， Compound lizard powder group and combination group all had certain inhibitory effects on the tumor growth in nude mice； the inhibitory rates of tumor increased significantly （P＜0.05）； the levels of inflammatory factors， the mRNA and protein expressions of MRP1， P-gp， GLUT1 and LDHA （except for cisplatin group）， the phosphorylation levels of PI3K and Akt protein （except for cisplatin group） as well as the protein expressions of HK2 and PKM2 were decreased significantly， while the combination group was significantly better than the cisplatin group （P＜0.05）. CONCLUSIONS Compound lizard powder may inhibit tumor growth in transplanted tumor model nude mice with gastric cancer-resistant cells by reducing the secretion of tumor-related inflammatory factors， inhibiting the expression of glycolysis， drug resistance-related proteins and genes， inhibiting the activation of the PI3K/Akt signaling pathway， thus having a certain effect of enhancing cisplatin efficacy and reversing drug resistance.

Objective To compare the clinical efficacy of three different therapies,including transjugular intrahepatic portosystemic shunt(TIPS)treatment,endoscopic treatment and medication treatment,combined with transhepatic arterial chemoembolization(TACE)in treating primary liver cancer complicated by portal hypertension and upper gastrointestinal bleeding.Methods A total of 105 patients with primary liver cancer associated with portal hypertension and upper gastrointestinal bleeding,who were admitted to the No.980 Hospital of PLA Joint Logistics Support Forces of China to receive treatment between January 2014 and June 2020,were enrolled in this study.According to the therapeutic scheme,the patients were divided into TIPS+TACE group(TIPS group,n=25),endoscopy+TACE group(endoscopy group,n=30),and medication+TACE group(medication group,n=50).The clinical efficacy,recurrence rate of bleeding,incidence of hepatic encephalopathy,and survival rate were compared between each other among the three groups.Results The differences in the postoperative 6-month,12-month and 24-month recurrence rates of bleeding between each other among the three groups were statistically significant(all P＜0.05).In TIPS group,the portal vein pressure decreased from preoperative(38.47±9.35)mmHg(1 mmHg=0.133 kPa)to postoperative(25.24±5.68)mmHg,the difference was statistically significant(P＜0.05).After treatment,the hemoglobin level in the three groups showed varying degrees of elevation,which in the TIPS group and endoscopy group were better than that in the medication group,the differences were statistically significant(P＜0.05).In all three groups,the differences in the recurrence rate of bleeding between postoperative 6-month value,12-month value and 24-month value were statistically significant(all P＜0.05).The postoperative 6-month,12-month and 24-month recurrence rates of bleeding in the TIPS group were lower than those in the endoscopy group and the medication group,and the differences were statistically significant(P＜0.05).The postoperative 12-month and 24-month recurrence rates of bleeding in the TIPS group were lower than those in the endoscopy group,and the differences were statistically significant(P＜0.05).The postoperative 12-month and 24-month recurrence rates of bleeding in the endoscopy group were lower than those in the medication group(P＜0.05),and the difference in the postoperative 6-month recurrence rate of bleeding between the two groups was not statistically significant(P＞0.05).The postoperative 6-month and 12-month incidences of hepatic encephalopathy in the TIPS group were higher than those in the endoscopy group and the medication group,the differences were statistically significant(P＜0.05),while the differences in the postoperative 6-month and 12-month incidences of hepatic encephalopathy between the endoscopy group and the medication group were not statistically significant(P＞0.05),and the differences in the postoperative 24-month incidence of hepatic encephalopathy between each other among the three groups were not statistically significant(P＞0.05).No statistically significant difference in the 6-month mortality existed between TIPS group and endoscopy group(P＞0.05),and the 6-month mortality of both TIPS group and endoscopy group was remarkably lower than that of the medication group(P＜0.05).The postoperative 12-month mortality and 24-month mortality in TIPS group were lower than those in the endoscopy group and the medication group,and the differences were statistically significant(P＜0.05),but the differences in the postoperative 12-month mortality and 24-month mortality between the endoscopy group and the medication group were not statistically significant(P＞0.05).Conclusion For primary liver cancer associated with portal hypertension and upper gastrointestinal bleeding,TIPS combined with TACE can effectively control tumor progression and prolong survival.(J Intervent Radiol,2024,32:33-37)

BACKGROUND:Diabetic ulcers are a common complication of diabetes mellitus,which is manifested as foot ulcers complicated with infection,long treatment cycle,high disability rate and mortality rate,and brings a heavy burden to patients and social care. OBJECTIVE:To review the mechanism of action and the latest treatment progress of traditional Chinese medicine(TCM)in the treatment of diabetic ulcers,and to provide a basis for further theoretical research and clinical application. METHODS:CNKI,WanFang Database and PubMed database were searched for relevant literature using the keywords of"diabetic ulcer,medicinal herb,inflammation,interleukin-1β,interleukin-6,tumor necrosis factor,hypersensitive C-reactive protein,γ-interferon,interleukin-4,interleukin-10"in Chinese and English,respectively.The relevant literature in recent years was searched,and finally 75 articles were included for review. RESULTS AND CONCLUSION:The high glucose environment of the body will increase the level of pro-inflammatory cytokines,so that diabetic ulcer wounds are in a state of chronic inflammatory response for a long time,and difficult to heal or even not heal.TCM has summed up a lot of experience in the long-term struggle with diabetic ulcer.At present,TCM divides diabetic ulcers into four syndrome types:dampness and heat poison syndrome,blood and blood stasis obstruction pattern,heat poison injury Yin pattern,and Qi and blood deficiency syndrome,as well as representative prescriptions for treatment.According to their clinical characteristics,diabetic ulcers can be also divided into three stages:primary,middle and late stages.Different treatment methods are proposed:"clear method,""warm and clear combined use"and"maintenance method."Under the guidance of dialectical typing and staging of TCM,TCM monomers,extracts and compounds inhibit the inflammatory response and promote the healing of diabetic ulcers by down-regulating the expression of pro-inflammatory factors and/or up-regulating the expression of anti-inflammatory factors.Compared with modern medicine,TCM has significant advantages in the treatment of diabetic ulcers.There are many TCM monomers,extracts and compounds for the treatment of diabetic ulcers,such as angelica,curcumin,improved Chonghe ointment,Sanhuang blood exhaustion prescription and sore-ulcer I.formula,etc.It has been found that TCM for the treatment of diabetic ulcers is mainly heat-clearing and detoxifying,invigorating blood circulation and removing blood stasis,and amassing sores and muscle-building drugs,and the frequency of use,treatment scope and therapeutic effect of TCM compounds are obviously better than those of TCM monomers and extracts.Among them,the most commonly used are the Sanhuang blood exhaustion prescription and the sore-ulcer I as well as prescription for the treatment of damp heat toxicity syndrome and Zizhu ointment for the treatment of non-ischemic diabetic ulcers.However,there are also some shortcomings in the treatment of diabetic ulcers with TCM.First,there are few clinical syndrome studies on diabetic ulcers.Secondly,there are a wide variety of TCM monomers,extracts and compounds for the treatment of diabetic ulcers,and the relevant research is insufficiently in-depth.Finally,the research on the mechanism underlying TCM treatment of diabetic ulcers is still in the preliminary exploration stage,and the mechanism of action still needs to be further explored.In the future,it is necessary to strengthen the research on the pharmacology of TCM and the clinical syndrome of diabetic ulcers,analyze the potential targets and related signaling pathways of TCM in the treatment of diabetic ulcers,give full play to the therapeutic advantages of TCM with multiple targets,multiple pathways,multiple levels and multiple systems,and develop TCM with significant efficacy,active ingredients and clear targets.
