Objective:To explore the effects of Bailing capsules combined with salvianolate on inflammatory cytokines, renal vas-cular endothelia and renal function in diabetic nephropathy inⅣphase. Methods:Totally 60 patients with diabetic nephropathy in IV phase were randomly divided into the control group (30 cases) and the treatment group (30 cases). The control group was given the conventional and salvianolate therapy, and the treatment group was treated with Bailing capsules additionally. The treatment course was 3 months. The changes of serum creatine(SCr), urean itrogen (BUN), creatinine clearance rate (Ccr), ethelin (ET-1), interleukin-6 (IL-6), tumor necrosis factor (TNF-a) and C-reactive protein (CRP) were detected before and after the treatment. Results:After the 3-month treatment, SCr, BUN, IL-6, TNF-a, CRP and ET-1 were significantly decreased in the two groups with statistical signifi-cance, and Ccr was significantly increased in the treatment group (P<0. 05), and the changes in the treatment group were significant-ly better than those in the control group (P<0. 05). After the treatment, the blood glucose, blood lipids, glycosylated hemoglobin and the other indicators had no significant changes in the two groups (P>0. 05). There was no significant difference in the incidence of adverse drug reactions between the two groups (P>0. 05). Conclusion:The combination of Bailing capsules and salvianolate can re-duce the inflammatory reaction and improve renal vascular endothelial function and renal function in the patients with diabetic nephrop-athy in Ⅳ phase with promising safety and few adverse reactions.

Objective To explore the value of combined detection of lipoprotein-associated phospholipase A2(Lp-PLA2),neuron specific enolase(NSE)and S-100 calcium binding protein β(S-100β)in the diagnosis and prognosis evaluation of acute cerebral infarction(ACI)in patients with carbon monoxide poisoning(CMP).Methods A total of 102 patients with CMP complicated with ACI admitted to the hospital from Jan-uary 2020 to November 2021 were selected as the study group,meanwhile,102 patients with simple CMP were enrolled as the control group.Patients in the study group were followed up for 6 months after discharge,ac-cording to the follow-up results,they were grouped into good prognosis group(60 cases)and poor prognosis group(42 cases).The serum levels of Lp-PLA2,NSE and S-100β were detected by enzyme-linked immunosor-bent assay(ELISA).The receiver operating characteristic(ROC)curve was applied to analyze the value of the combination of serum Lp-PLA2,NSE and S-100β in the early diagnosis and prognosis evaluation of patients with CMP and ACI.Results Compared with the control group,the levels of Lp-PLA2,NSE and S-100β in the study group were obviously higher(P<0.05).The ROC curve analysis results showed that the area under the curve(AUC)of the combined detection of serum Lp-PLA2、NSE、S-100β for the diagnosis of CMP complicat-ed with ACI was greater than the AUC of single detection of each indicator(P<0.001).Compared with the good prognosis group,the levels of Lp-PLA2,NSE and S-100β in the poor prognosis group were obviously higher(P<0.05).The results of ROC curve analysis showed that the AUC of the combined detection of ser-um Lp-PLA2、NSE、S-100β for the prognosis of patients with CMP complicated with ACI was greater than the AUC of single detection of each indicator(P<0.05).Conclusion The expression of Lp-PLA2,NSE and S-100β in serum of patients with CMP complicated with ACI is high,and the combined detection of the three has certain value in the diagnosis and prognosis evaluation for patients with CMP complicated with ACI.

【Objective】 To explore the characteristics of esophageal motility and reflux of endoscopic-negative heartburn patients based on the Lyon Consensus Diagnostic Criteria and discuss the differential diagnosis value of the mean nocturnal baseline impedance （MNBI） and the postreflux swallow-induced peristaltic wave （PSPW） index for reflux hypersensitivity （RH） and functional heartburn （FH） patients. 【Methods】 We enrolled 132 patients with heartburn as the main symptom who visited the Gastroenterology Department of our hospital from January 2017 to June 2021， including 24 in the non-erosive reflux disease （NERD） group， 24 in the RH group， and 84 in the FH group. All the patients completed gastroscopy， esophageal high-resolution manometry and 24h-pH impedance monitoring. We analyzed and compared the related indexes of esophageal motility and reflux. The receiver operating characteristic （ROC） curve was used to analyze the esophageal proximal MNBI， distal MNBI， and PSPW indexes for the differential diagnosis of RH and FH. 【Results】 The lower esophageal sphincter （LES） average resting pressure， LES residual pressure and intact relaxation pressure （IRP） in NERD were lower than those in RH and FH （P<0.05）. The number of acid reflux， the upright acid exposure time （AET）， the supine position AET， the total AET， and the DeMeester score were higher in NERD than in RH and FH （P<0.05）. The non-acid reflux， distal MNBI and PSPW indexes were lower in NERD than in RH and FH （P<0.05）. The distal MNBI and PSPW indexes were lower in RH than in FH （P<0.05）. However， there was no significant difference in proximal MNBI among the three groups （P>0.05）. When the proximal MNBI， distal MNBI， and PSPW indexes were used alone respectively to diagnose RH， the area under the ROC curve was 0.480， 0.810， 0.682， respectively， with the sensitivities being 87.5%， 100% and 91.7%， and the specificities being 26.2%， 66.7% and 51.2%， respectively. 【Conclusion】 NERD patients have obvious abnormal esophageal dynamics， mainly manifested as LES relaxation， which further aggravates the pathological acid reflux， while patients with RH and FH are mainly exposed to physiological acid or non-acid reflux. In patients with endoscopic negative heartburn， distal MNBI value can improve the clinical diagnosis rate of RH and help distinguish RH from FH.
