Objective To investigate the expression levels of serum G protein-coupled receptor-associated sorting protein 1(GASP-1),lipocalin-2(LCN2)and targeting protein for Xenopus kinesin-like protein 2(TPX2)in lung cancer patients,and their correlations with tumor-node-metastasis classification(TNM)pathological stage and prognosis.Methods A total of 92 patients with lung cancer who were admitted to General Hospital of Southern Theatre Command from April 2019 to May 2022 were selected as observation group.Meanwhile,92 healthy subjects were selected as control group.Peripheral venous blood samples of the two groups were collected to detect serum GASP-1,LCN2 and TPX2 levels.Serum GASP-1,LCN2 and TPX2 levels of lung cancer patients with different TNM stages were analyzed.According to the prognosis,the patients were divided into good prognosis group and poor prognosis group.Serum GASP-1,LCN2 and TPX2 levels were compared between the two groups.The correlations of serum GASP-1,LCN2 and TPX2 levels with TNM stage and prognosis in patients with lung cancer were investigated.Results The serum GASP-1,LCN2 and TPX2 levels in the observation group were significantly higher than those in the control group(P＜0.05).The serum levels of GASP-1,LCN2 and TPX2 in patients with TNM stage Ⅲ and Ⅳ were significantly higher than those in patients with TNM stage Ⅰand Ⅱ(P＜0.05).The levels of serum GASP-1,LCN2 and TPX2 in patients with TNM stage Ⅳ were significantly higher than those in patients with TNM stage Ⅲ(P＜0.05).Serum GASP-1,LCN2 and TPX2 levels in the good prognosis group were significantly lower than those in the poor prognosis group(P＜0.05).Serum GASP-1,LCN2 and TPX2 levels were positively correlated with TNM stage before treatment(P＜0.05),but were negatively correlated with the prognosis after treatment(P＜0.05).Conclusion Serum levels of GASP-1,LCN2 and TPX2 may be related to the TNM pathological stages of lung cancer patients.The detection of the above serum indicators after treatment can reflect the prognosis of patients to a certain extent,and provide reference for clinical practice.

Objective:To explore the difference of the vessel and plaque characteristics, myocardial perfusion and cardiac function between patients with ischemia with non-obstructive coronary artery disease (INOCA) and obstructive coronary artery disease (CAD).Methods:From July 2021 to June 2022, 101 patients with angina were referred to dynamic computed tomography myocardial perfusion (CTP) and coronary computed tomography angiography (CCTA) and retrospectively included in our hospital. Based on the results of CTP and CCTA, patients were divided into INOCA (27 cases), moderate obstructive CAD (26 cases) and severe obstructive CAD (48 cases). The anatomical coronary artery stenosis, plaque characteristics and myocardial perfusion features of all patients were analyzed. Furthermore, left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) were obtained on full-phase reconstruction CCTA image by using Medis Suite 3.2 postprocessing software. Multigroup analysis used one way ANOVA or Kruskal Wallis H test. Results:Patients with INOCA were younger than patients with moderate and severe obstructive CAD ( P<0.001). INOCA patients (7.4%, 2/27) had lower rate of positive remodeling than both moderate (57.7%, 15/26, P<0.001) and severe obstructive CAD patients (33.3%, 16/48, P=0.017). The percentage of ischemic myocardium volume in patients with INOCA were similar with those in patients with severe CAD (all P>0.05), but significantly higher than those in patients with moderate CAD (all P<0.05). No significant difference in terms of GLS was detected between patients with INOCA [-17.4% (-21.6%, -11.6%)] and severe CAD [-17.6% (-21.9%, -14.8%), P=0.536], however, patients both with INOCA and severe CAD also had higher GLS than patients with moderate obstructive CAD [-22.3% (-29.8%, -19.0%), all P<0.05]. Conclusions:Based on"one-stop-shop"CTP combined with CCTA imaging, early cardiac functional changes including abnormal myocardial perfusion and myocardial strain in INOCA patients were similar to those in patients with severe obstructive CAD and more severe than those in patients with moderate obstructive CAD.

Objective To study the clinical effect of total parathyroidectomy (TPTX) on treatment of secondary hyperparathyroidism (SHPT) in patients with chronic renal failure.Methods 24 patients undergoing TPTX in Mianyang Central Hospital from Jan.2014 to Nov.2016 were retrospectively analyzed.The preoperative,postoperative and follow-up intact parathyroid hormone (iPTH),serum calcium,serum phosphorus and calciumphosphorus product were statistically analyzed.The postoperative complications and recurrence were observed.Results For preoperative,1 week after operation,3 months after operation,6 months after operation,12 months after operation,24 months after operation and 36 months after operation,the mean values of iPTH were (1771.7± 244.5) pg/ml,(70.2±18.2) pg/ml,(106.5±35.3) pg/ml,(114.3±31.3) pg/ml,(122.1±27.8) pg/ml,(128.1±12.5) pg/ml and (113.8±24.9) pg/ml.The mean values of serum calcium were (2.6±0.4) mmol/L,(1.9±0.4) mmol/L,(2.1±0.3) mmol/L,(2.1±0.2) mmol/L,(1.8±0.2) mmol/L,(1.8±0.2) mmol/L and (1.8±0.3) mmol/L.The mean values of serum phosphorus were (2.1±0.7) mmol/L,(1.4±0.6) mmol/L,(1.3±0.4) mmol/L,(1.4±0.3) mmol/L,(1.3±0.3) mmol/L,(1.5±0.2) mmol/L and (1.4±0.4) mmol/L.The mean values of calcium-phosphorus product were (61.9±17.0) mg2/dl2,(34.6±19.4) mg2/dl2,(37.4±14.4) mg2/dl2,(40.4±12.3) mg2/dl2,(29.2±5.3) mg2/dl2,(35.0 ±7.1) mg2/dl2 and (32.4 ± 11.3) mg2/dl2,respectively.Compared with those before operation,postoperative iPTH,serum calcium,serum phosphorus and calcium-phosphorus product decreased significantly at 1 week after operation,3 months after operation,6 months after operation,12 months after operation,24 months after operation and 36 months after operation,and the differences had statistical significance (all P＜0.05).Temporary injury of recurrent laryngeal nerve was found in one patient (4.2％).Early postoperative hypocalcemia rate was 91.7％ (22/24).No recurrence developed after operation.Conclusion TPTX is safe and effective in treatment of SHPT in patients with chronic renal failure,with low recurrence rate and satisfactory treatment outcome.

Objective To investigate the effect of an ACE inhibitor ,perindopril ,on the expression of SR‐A in renal tubuloint‐erstitium of diabetic rats .Methods Diabetes was induced in male Sprague‐Dawley rats by injection with streptozotocin .The rats were then randomly divided into 3 groups:normal control group;untreated diabetes mellitus group and diabetes mellitus group trea‐ted with perindopril .After a 24‐week treatment ,tubulointerstitial injury index was assessed with Masson′s trichrome sections .The expression of SR‐A mRNA was detected by RT‐PCR and the expression of SR‐A protein in renal tubulointerstitium was detected by immunohistochemistry .Results The tubulointerstitial injury index ,the expression of SR‐A mRNA were significantly higher in the diabetes group than those in normal control group .Perindopril treatment not only attenuated the tubulointerstitial injury ,but also reduced the overexpression of SR‐A mRNA in diabetic rats .The expression of SR‐A protein was most obvious in renal tubulointer‐stitium in diabetic rats ,which was obviously attenuated by perindopril treatment(P<0 .05) .Conclusion The findings of the this study indicate that perindopril may have renoprotective effects on diabetic nephropathy via inhibiting the expression of SR‐A in re‐nal tubulointerstitium .

Objective To analyze and compare efficacy and safety of different chemotherapy regimens in the treatment of elderly patients with advanced gastric cancer. Methods 60 elderly patients admitted to our hospital with advanced gastric cancer were selected as research subjects , and divided into experimental group and control group depending on the treatment of chemotherapy. The experimental group were treated with Gio oxaliplatin (SOX), and patients in the control group accepted Olivier Elizabeth, leucovorin and fluorouracil (FOLFOX6) treatment. Compare and analyze the efficacy of the two groups after two cycles of therapy. Results By chemotherapy, recent efficiency and disease control rate were not significantly different (P>0.05) between the two groups;and there was also no significant difference in the incidence of adverse reactions,such as adverse reactions, fatigue weakness, gastrointestinal reactions, hand-foot syndrome, oral mucositis (P > 0.05). Conclusion The efficacy was equivalent between FOLFOX6 chemotherapy SOX test group and the control group in the treatment of elderly patients with advanced gastric , and there was no significant difference in the incidence of adverse reactions.

Objective To explore the effect of ACE-inhibitor perindopril on the expression of scavenger receptor A (SR-A) gene in the kidney of diabetic rats.Methods Diabetes were induced in male Sprague-Dawley rats by peritoneal injection with streptozotocin (60mg/kg).The rats were then random di vided into normal control group, diabetes group and ACEI treatment group [4mg/(kg·d) for 24 weeks].Blood glucose concentration and 24h urinary albumin excretion were determined.The renal morphological change was observed.Immunohistochemistry was used to analyze CD68 positive macrophages,and the Mrna of SR-A in renal tissue was detected by quantitative real-time PCR.Results Compared with normal control group,blood glucose concentration,24h urinary albumin excretion and the number of CD68 positive macrophages were significantly increased [(5.3 ± 0.6) mmol/L vs (26.7 ± 3.3) mmol/L;(2.7 ± 1.3) mg/24h vs (26.7 ± 1.8)mg/24h;(0.77 ±0.24)/gcs vs (2.55 ±0.46)/gcs;(6.13 ±0.50)/HPF vs (11.9 ±2.12)/HPF;P ＜0.05],and the expression of SR-A Mrna were significantly up-regulated in diabetes group [ (5.6 ± 1.2 vs 1.5 ±0.2),P ＜0.05].After intervention with ACE-inhibitor,the up-regulations of the above mentioned parameters,except blood glucose concentration,were all significantly inhibited [ (3.6 ±1.4)mg/24h;(1.03±0.37)/gcs;(8.28±1.19)/HPF;3.4±0.7;P ＜0.05].Conclusion ACE-inhibitor might have renoprotective effects of diabetic nephropathy,it probably was associated with inhibiting the expression of SR-A gene.
