Objective To investigate the clinical effect and safety of bronchial arterial chemoembolization(BACE)combined with micro wave ablation(MW A)and immunotherapy in treating patients with advanced lung squamous cell carcinoma.Methods The clinical data of 68 patients with advanced lung squamous cell carcinoma,who were admitted to the North Jiangsu People's Hospital of China from June 2020 to June 2022 to receive treatment,were retrospectively analyzed.According to the therapeutic method,the patients were divided into control group(n=30,receiving BACE combined with immunotherapy)and observation group(n=38,receiving BACE followed by MW A,which was performed with CT-guided localization of the lung lesion,and immunotherapy in 3-5 days after BACE).Results The surgical success rate in both the 30 patients of the observation group and the 38 patients of the control group was 100％.After treatment,no surgery-related or chemoembolization-related serious complications occurred in both groups.In the control group and the observation group,the mean progression-free survival(PFS)was(5.70±1.61)months and(12.10±0.72)months respectively,the mean overall survival(OS)was(11.80±1.10)months and(13.00±1.13)months respectively.The PFS of the observation group was obviously longer than that of the control group(P＜0.05),and no statistically significant difference in OS existed between the two groups(P=0.255).Conclusion BACE combined with MW A and immunotherapy can effectively control the advanced lung squamous cell carcinoma,it has reliable short-term efficacy when compared with BACE plus immunotherapy,and it can inhibit tumor growth and prolong the PFS of patients,with a trend of extending OS and a satisfactory clinical safety.

Objective To discuss the clinical efficacy of microwave ablation(MWA)combined with percutaneous vertebroplasty(PVP),radiofrequency ablation(RFA)combined with PVP,and simple PVP in the treatment of vertebral metastatic tumors.Methods A total of 65 patients with vertebral metastatic tumors,who were admitted to the Northern Jiangsu People's Hospital of China to receive treatment from January 2019 to June 2023,were enrolled in this study.The patients were divided into MWA plus PVP group(M+P group,n=25,27 diseased vertebral bodies in total),RFA plus PVP group(R+P group,n=20,23 diseased vertebral bodies in total),and simple PVP group(P group,n=20,24 diseased vertebral bodies in total).Visual analog scale(VAS)score was used to assess the preoperative pain degree and the postoperative relief degree.Bone cement distribution and leakage at one week after surgery were evaluated.Results Successful operation was accomplished in all of the patients.No serious procedure-related complications occurred in all the patients of three groups.In R+P group,P group and M+P group,the preoperative mean VAS scores were(8.48±0.80)points,(8.57±0.98)points and(8.20±1.00)points respectively;the differences among the three groups were not statistically significant(P＞0.05).One week after operation,the pain was significantly relieved in all the patients of three groups;the mean VAS scores in R+P group,P group and M+P group were(4.10±0.85)points,(3.17±0.93)points and(2.44±1.23)points respectively,and the reduction in VAS score was most pronounced in M+P group(P＜0.05).Six months after operation;the mean VAS scores in R+P group,P group and M+P group were(1.87±0.84)points,(4.60±1.09)points and(1.48±0.71)points respectively;and the reduction in VAS score was most pronounced in the M+P group(P＜0.05).The used amount of bone cement in M+P group,R+P group and P group was(7.54±1.44)mL,(5.48±1.12)mL and(4.59±1.56)mL respectively,the difference among the three groups was statistically significant(P＜0.05).The vascular leakage rate(34.8％)and non-vascular leakage rate(52.2％)in P group were remarkably higher than those in R+P group and in M+P group(P＜0.05).No statistically significant difference in the rate of cement leakage existed between R+P group and M+P group(P＞0.05).Conclusion For the treatment of vertebral metastases,MW A plus PVP is superior to RFA plus PVP in pain relief rate.

Objective To comparatively observe the value of TIPS combined with catheter-directed thrombolysis and percutaneous transhepatic portal vein catheterization thrombolysis for acute non-cirrhotic non-neoplastic portal vein thrombosis(PVT).Methods Twenty-five patients with acute non-cirrhotic non-neoplastic PVT were retrospectively enrolled and clustered into TIPS group(n=17,underwent TIPS combined with catheter-directed thrombolysis)and liver puncture group(n=8,underwent percutaneous transhepatic portal vein catheterization thrombolysis)according to the access of thrombolysis.The technical success rate,duration of catheter-directed thrombolysis,complications within 7 days,as well as portal vein patency 3 months after treatment,Child-Pugh grading of liver function and occurrence of hepatic encephalopathy(HE)were recorded and compared between groups.Results The technical success rates were both 100%in 2 groups.There was no significant difference of the duration of catheter-directed thrombolysis between groups(P＞0.05).The thrombolytic effect in TIPS group was better than that in liver puncture group(P＜0.05).No significant difference of the occurrence of bleeding within 7 days was found between groups(P＞0.05).After 3 months'follow-up,the degree of portal vein patency in TIPS group was higher than that in liver puncture group(P＜0.05).No significant difference of Child-Pugh grading of liver function nor occurrence of HE was found between groups(both P＞0.05).Conclusion Both TIPS combined with catheter-directed thrombolysis and percutaneous transhepatic portal vein catheterization thrombolysis were effective for treating acute non-cirrhotic non-neoplastic PVT,and the thrombolytic effect of the former was better than the latter.

Stroke is a prevalent acute cerebrovascular disease associated with significant morbidity and mortality,which highly demand effective prevention and treatment strategies.Glucagon-like peptide-1 receptor agonists(GLP-1RA)is a novel type of antidiabetic drug that exerts hypoglycemic and weight loss effects on GLP-1 receptors.Additionally,GLP-1RA possess the potential to reduce infarction size and promote nerve recovery by inhibiting inflammation,oxidative stress,apoptosis,and improving blood-brain barrier permeability and other pathologies.This paper provides a comprehensive summary of the role of GLP-1 in stroke occurrence while also explores the underlying mechanisms by which GLP-1RA influences stroke pathogenesis.Furthermore,it briefly reviews the therapeutic efficacy of GLP-RA in managing stroke.

Objective:To explore the characteristics of type 3 secretion system and biofilm of Pseudomonas aeruginosa in diabetic foot wound, and to analyze the relationship between these factors, as well as to the antibiotic sensitivity.Methods:Thirty-three strains of Pseudomonas aeruginosa were collected from the foot wounds of diabetic foot inpatients in Tianjin Medical University Chu Hsien-I Memorial Hospital from February 1, 2018 to December 31, 2018. Thirteen strains of Pseudomonas aeruginosa were collected from non-diabetic wounds. All strains were tested for antibiotic sensitivity. The virulence genes exoS or exoU of Pseudomonas aeruginosa and the ability of biofilm formation were tested. The characteristics of exoS or exoU and biofilm of Pseudomonas aeruginosa were analyzed. Patients′ clinical outcomes were also analyzed.Results:Pseudomonas aeruginosa with exoS gene was the major pathogen, 90.9% found in diabetic foot group and 84.6% in control group, with no significant difference( χ2=0.54, P=0.46). The drug-resistant strains of Pseudomonas aeruginosa with exoS accounted for 16.7% in diabetic foot group and 18.2% in control group, also with no significant difference( χ2=0.18, P=0.83). There were 5 strains of Pseudomonas aeruginosa carrying exoU, 3 strains in diabetic foot group, of which 1 was resistant, 2 in control group, no resistant strain. Pseudomonas aeruginosa increased the ability of biofilm formation in diabetic foot group, accounting for 57.6%, and for resistant strains, 83.3% of them increased the biofilm formation ability. Two kinds of Pseudomonas aeruginosa produced different biofilms, but they were effectiveless for carbapenem antibiotics. The times of debridement ( P<0.01), time of antibiotic use ( P<0.01) were more in biofilm wound, but the healing rate reached 75%-90%. Conclusion:Pseudomonas aeruginosa secreting ExoS is the main one in the diabetic foot wound. The ability of Pseudomonas aeruginosa to produce biofilm in DF wound is increased. Biofilm is one reason for its antibiotic resistance. Multiple debridement combined with sensitive antibiotics is an effective method to remove biofilm.

Objective: To investigate the correlation between serum melatonin level and cardiac function, blood lipid in patients of heart failure with preserved ejection fraction (HFpEF). Methods: One hundred and seventy patients with HFpEF (HFpEF group) in Ninth Hospital of Xi′an City from May 2016 to May 2018 were selected. According to the cardiac function grading of New York Heart Association (NYHA), Ⅱ grade (cardiac function Ⅱ grade) was in 98 cases, and Ⅲ grade (cardiac function Ⅲ grade) was in 72 cases. Then, 32 healthy volunteers were selected as control group. The 2 groups were sampled at 2:00 and 7:00, and the level of melatonin was detected by enzyme-linked immunosorbent assay. The correlation between serum melatonin level and cardiac function, blood lipid were analyzed (Pearson correlation), including triglyeride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), N-terminal precursor brain natriuretic peptide (NTproBNP), hypersensitive C reactive protein (hs-CRP), ejection fraction, left ventricular end-diastolic volume index (LVEDVI), miral diastolic early and end-diastolic maximum blood flow velocity ratio (E/A) and peak value of early diastolic blood flow velocity in the mitral valve and peak value of the early diastolic velocity of the mitral annulus (E/e′). Results: The TG, TC, LDL-C, NTproBNP and hs-CRP in cardiac function Ⅲ grade patients were significantly higher than those in cardiac function Ⅱ grade patients: (1.51 ± 0.69) mmol/L vs. (1.15 ± 0.75) mmol/L, (4.03 ± 1.02) mmol/L vs. (3.47 ± 0.94) mmol/L, (1.42 ± 0.33) mmol/L vs. (1.17 ± 0.31) mmol/L, (3 438.54 ± 553.58) ng/L vs. (3 034.58 ± 557.35) ng/L and (4.26 ± 2.54) mg/L vs. (3.12 ± 2.13) mg/L, the HDL-C, ejection fraction and E/A were significantly lower than those in cardiac function Ⅱ grade patients: (2.44 ± 0.88) mmol/L vs. (2.97 ± 0.94) mmol/L, (56.23 ± 5.26)% vs. (61.11 ± 5.33)% and 0.82 ± 0.18 vs. 0.91 ± 0.17, and there were statistical differences (P<0.01). The melatonin levels at 2:00 and 7:00 in control group and cardiac function Ⅱgrade patients of HFpEF group were significantly higher than those in cardiac function Ⅲ grade patients of HFpEF group: (454.24 ± 123.54) and (432.68 ± 155.68) ng/L vs. (368.85 ± 98.52) ng/L, (483.25 ± 90.54) and (418.54 ± 103.57) ng/L vs. (345.85 ± 98.52) ng/L, the melatonin level at 7:00 in control group was significantly higher than that in cardiac function Ⅱ grade patients of HFpEF group, and there was statistical difference (P<0.01). In cardiac function Ⅱ grade patients of HFpEF group, the melatonin level was correlated with TG, TC, LDL-C and HDL-C (P<0.01); In cardiac function Ⅲ grade patients of HFpEF group, the melatonin level was correlated with NTproBNP, hs-CRP, ejection fraction, LVEDVI, E/A, E/e′, TG, TC, LDL-C and HDL-C (P<0.01 or <0.05). Conclusions The melatonin level is correlated with the level of blood lipid in HFpEF patients. Melatonin level is correlated with cardiac function Ⅲ grade patients, but this phenomenon is not observed in cardiac function Ⅱ grade patients.

Objective To explore the effect of ankle pump on wound healing of diabetic foot ulcer (DFU). Methods Using convenience sampling method, patients hospitalized in Podiatry Department of Tianjin Medical University Metabolic Diseases Hospital from July to December 2015 and eligible for inclusion-exclusion criteria were recruited to control group, and patients who were hospitalized from May to October 2016 were recruited to observation group according inclusion-exclusion criteria. A total of 162 patients with DFU were recruited and 156 patients completed the whole study, with 72 cases in observation group and 84 cases in control group. Routine treatment and nursing care of DFU were given to both groups, and on the basis of that ankle pump motion therapy training was given to the observation group. After treatment for 9 weeks, the foot ulcer area, healing condition, transcutaneous arterial oxygen tension (TcPO2), foot skin temperature and ankle brachial index (ABI) were compared. In addition, the adverse events throughout the process of the two groups were recorded. Results After 9-week treatment, the healing rate of observation group was higher than the control group, and the difference wasn't statistically significant (χ2=3.714, P=0.054). The area of foot ulcer of both groups decreased, and the difference wasn't statistically significant before and after treatment (P<0.01). Ulcer surface area in the intervention group decreased more significantly after treatment than the control group(P<0.01). Wagner grading Ⅲ, Ⅳ patients' TcPO2, skin temperature of both groups,and wagner grading Ⅲ patients' ABI of oberservation group all increased than before treatment, with statistical difference (P> 0.05). There was no statistical difference of TcPO2, ABI and skin temperature between the two groups before treatment (P> 0.05). In observation group, Wagner grading Ⅱ patients' skin temperature and ABI, Wagner grading Ⅲ patients' TcPO2 and skin temperature, Wagner grading Ⅳ patients' TcPO2were all higher than those of the control group, with statistical difference (P<0.01). There were 4 cases of asymptomatic hypoglycemia in each group, and there was no statistical difference of adverse event in both groups. Conclusions The ankle pump motion has a positive effect on the wound healing of DFU, which has the advantage of high safety.

Objective To discuss the clinical application of percutaneous transhepatic removal of gall-stone technique in treating common bile duct (CBD) stones.Methods Between January 2013 and January 2015,a total of 25 patients with CBD stones underwent lithotomy procedure via percutaneous transhepatic route.First,under ultrasound or fluoroscopy guidance percutaneous transhepatic cholangiography (PTC) was performed with subsequent placement of an 8 F rsheath;then,a balloon of 8-12 mm diameter was employed to dilate the papilla;mechanical lithotripsy was adopted when the stone size exceeded 12 mm;finally,through guide-wire exchange technique the stone-retrieval balloon was used to push the stones into the intestinal tract through the sphincter of duodenal papilla.Results The reasons to receive percutaneous transhepatic removal of gall-stone technique in the 25 patients included previous gastrointestinal surgery (n=18),endoscopic treatment failure (n=3),unwilling to receive endoscopic treatment (n=3),and other reasons (n=1).Successful removal of stones was accomplished in all 25 patients.After the treatment,complications occurred in 3 patients (12％),including fever (n=2) and liver abscess formation (n=1).The patients were followed up for 0.5-3 years;two patients died of tumor recurrence and metastasis,and one patient developed recurrence of common bile duct stones.No reflux cholangitis occurred.Conclusion For the treatment of CBD stones,percutaneous transhepatic removal of gall-stone technique carries higher technical success rate with lower incidence of complications,therefore,this technique can be used for the patients who are not suitable for endoscopic treatment or in whom endoscopic treatment failed.

Objective To investigate the expressions of ALCAM,IL-17RA and PIK3CA in patients with non-small cell lung cancer,and to investigate the correlation between the above-mentioned indexes and patients′ prognosis.Methods A total of 65 patients with non-small cell lung cancer admitted to the third People′s Hospital in Liaocheng City were selected and were served as study objects.Immunohistochemical staining(S-P) method was used to detect the expression of ALCAM,IL-17RA and PIK3CA in tissues to analyze the difference of expression between different pathological parameters.And 65 patients were followed up after the operation to compare the survival time of patients in the negative expression group and the positive expression group,and to analyze the correlation between ALCAM,IL-17RA and PIK3CA and the prognosis of the disease.Results Among the 65 cases of patients,47 cases were positive for ALCAM with the positive rate of 72.3%,34 cases were positive for IL-17RA with the positive rate of 52.3%;31 cases were positive for PIK3CA with the positive rate of 47.7%.There was significant difference in the expression of ALCAM,IL-17RA and PIK3CA in patients with different pathological types,TNM staging and lymph node metastasis(P<0.05).There was no significant statistical difference in the expression of patients with different genders and ages(P>0.05).The median survival time of patients with positive results of ALCAM,IL-17RA and PIK3CA were lower than those of negative group,and the differences were statistically significant(P<0.05).Conclusion The expression of ALCAM,IL-17RA and PIK3CA increased in non-small cell lung cancer tissues to remind the higher degree of malignancy and poor prognosis.

Objective To investigate the serum expressions and clinical significance of Dickkopf-1 in patients with rheumatoid arthritis (RA). Methods The clinical data of 139 patients with RA were retrospectively analyzed, including the disease history, tender joint count (TJC), swollen joint count (SJC), platelet, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), anti-nuclear antibody (ANA), antikeratin antibody (AKA), anti-perinuclear factor (APF), anti cyclic citrullinated peptide antibody (anti-CCP), Dickkopf-1 and radiological (X-ray) staging. The disease activity scale (DAS) was evaluated, and the ESR and CRP levels were included. The relationship between Dickkopf-1 and the clinical data of RA, DAS44 score was analyzed. Results The serum level of Dickkopf-1 in patients with RA was (2.70 ± 0.46) μg/L. There was no relationship between serum Dickkopf-1 level and gender, age, course of disease, CRP, platelet, ANA, AKA, APF, RF, radiological staging in patients with RA (P>0.05). The serum Dickkopf-1 level was significantly associated with TJC, SJC, ESR, DAS44-ESR score, DAS44-CRP score and anti-CCP (r = 0.200, 0.291, 0.178, 0.222, 0.199 and 0.278, P = 0.019, 0.001, 0.037, 0.009, 0.028 and 0.012). Conclusions The serum Dickkopf-1 expression level is closely related to the occurrence and development of RA. Dickkopf-1 may contribute to diagnose the disease activity in patients with RA.
