Objective: To investigate the application value of hs-CRP and BNP detection in COPD patients with pulmonary heart disease. Methods: From January 2016 to January 2018, 80 patients with COPD in the Fifth People's Hospital of Datong were selected.Forty-two COPD patients complicated with pulmonary heart disease were selected as COPD and cor pulmonale group, 38 COPD patients without pulmonary heart disease were selected as COPD group, and 30 healthy volunteers were selected as control group.The differences of hs-CRP and BNP levels were compared, and the diagnostic value of hs-CRP and BNP for COPD combined with pulmonary heart disease was analyzed. Results: There were statistically significant differences in hs-CRP[(72.5±20.4) mg/L vs.(37.5±9.8) mg/L vs.(3.7±1.2)mg/L], BNP[(362.8±86.9) ng/L vs.(125.9±34.8) ng/L vs.(28.5±9.9)ng/L] among the COPD and cor pulmonale group, COPD group and control group (F=9.245, 14.668, all P<0.05). The hs-CRP and BNP levels in the COPD and cor pulmonale group were significantly higher than those in the other two groups(t=19.294, 11.576, 21.385, 9.258, 9.258, all P<0.05), which of the COPD group were significantly higher than those of the control group (t=8.912, 12.567, all P<0.05). The best boundary value of BNP in diagnosis of COPD with cor pulmonale was 261.8ng/L, and its diagnostic sensitivity and specificity were 96.2% and 85.4%, respectively, the area under the line was 0.834, which were all higher than those of hs-CRP.With the increase of cardiac function, the levels of hs-CRP[(38.5±10.3) mg/L vs.(51.4±14.8) mg/L vs.(75.1±21.5) mg/L vs.(93.7±31.8)mg/L], BNP[(142.8±56.5) ng/L vs.(285.9±94.8) ng/L vs.(352.5±118.2) ng/L vs.(478.5±130.3)ng/L] increased, the differences were statistically significant (F=13.577, 16.776, all P<0.05). There were significant correlation between hs-CRP, BNP levels and COPD patients complicated with cor pulmonale (r=0.675, 0.766, all P<0.05). Conclusion hs-CRP and BNP have high diagnostic potency for COPD patients combined with cor pulmonale, and are positively correlated with cardiac function classification.

To evaluate the diagnostic value and safety of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in patients with biopsy-negative malignant gastrointestinal stricture, a retrospective analysis was performed on data of patients whose computed tomography scan showed gastrointestinal malignant tumor with complete lumen stricture and endoscopic biopsy results showed negative, who underwent EUS-FNA in the Second Affiliated Hospital of Soochow University from July 2016 to January 2020. Perioperative complications, technical success rate and accuracy of EUS-FNA were analyzed. Eleven cases included in the study, including 7 males and 4 females, with mean age of 60.3 years. There were 8 esophageal strictures and 3 rectal strictures. All patients successfully underwent EUS-FNA, and malignant tumor was found in 10 cases and no tumor cell was found in 1 case. No complications were reported. EUS-FNA is a safe and valuable approach to diagnosing biopsy-negative malignant gastrointestinal strictures.

Objective:To evaluate the preoperative localization value of endoscopic ultrasound guided fine needle tattooing (EUS-FNT) for laparoscopic distal pancreatectomy in pancreatic lesions with a maximum diameter ≤3 cm.Methods:From November 2017 to October 2022, at the Second Affiliated Hospital of Soochow University, the data of patients with pancreatic lesions ≤3 cm who underwent laparoscopic distal pancreatectomy were retrospectively analyzed. Eight patients who underwent EUS-FNT assisted laparoscopic distal pancreatectomy were included in the fine needle tattooing (FNT) combined laparoscopic group. And 14 patients who underwent simple laparoscopic distal pancreatectomy were taken as the simple laparoscopic group. The success rate and complications of EUS-FNT were observed. The differences in operation time, surgery-related complications and complete resection rate of lesions between the two groups were compared. Mann-Whitney U test and descriptive analysis were used for statistical analysis. Results:In the FNT combined laparoscopic group, the lesions of 4 cases were located in the pancreatic body and 4 cases in the pancreatic tail. In the simple laparoscopic group, the lesions of 4 cases were located in the pancreatic body and 10 cases in the pancreatic tail. There was a significant difference in lesion size between the two groups (14.5 mm (10.8 mm, 16.5 mm) vs. 27.0 mm (23.5 mm, 30.0 mm), Z=-3.09, P=0.001). In the FNT combined laparoscopic group, EUS-FNT was successfully performed in all 8 patients. The average time of laparoscopy after EUS-FNT was (98.4±8.8) min. The marks were clearly visible under the laparoscopic field of view, and no complications such as abdominal hemorrhage and hematoma were observed. Laparoscopic pancreaticocaudectomy was performed in 5 cases and pancreaticocaudectomy plus splenectomy in 3 cases. The median operation time was 192.5 min (176.3 min, 203.8 min). The amount of intraoperative bleeding was large in 2 patients and blood transfusion was needed. The lesions were one-time completely resected in all 8 patients. The postoperative pathology were 6 cases of pancreatic neuroendocrine neoplasm, 1 case of intraductal papillary mucinous neoplasm (IPMN), and 1 case of solid pseudopapilloma. In the simple laparoscopic group, laparoscopic pancreaticocaudectomy was performed in 2 cases and pancreaticocaudectomy plus splenectomy in 12 cases. The median operation time was 202.5 min (192.8 min, 235.0 min), which was longer than that of FNT combined laparoscopic group, but the difference was not statistically significant ( P>0.05). The amount of intraoperative bleeding was large in 2 patients and blood transfusion was needed. In 1 patient with pancreatic body lesions, no lesion was found in the specimen examination after the first pancreatectomy, and the lesions were completely resected after the second partial pancreatectomy. Active abdominal hemorrhage occurred in 1 patient on the second day after operation, and underwent interventional embolization for hemostasis. Two weeks after surgery, 1 patient was found to have a encapsulated fluid with a long diameter of 6 cm around the pancreas by computed tomography re-examination 2 weeks after surgery. The postoperative pathology were 5 cases of pancreatic neuroendocrine neoplasm, 2 cases of IPMN, 1 case of solid pseudopapilloma, 1 case of pancreatic cyst with glandular low-grade intraepithelial neoplasia, 1 case of ectopic spleen, and 4 cases of pancreatic ductal adenocarcinoma. Conclusion:EUS-FNT can effectively localize small pancreatic lesions before laparoscopic distal pancreatectomy, shorten the operation time and improve the complete resection rate under laparoscopy.

Objective:To describe the clinical features of a patient of anti-neurofascin 186 (NF186) antibody associated acute immune sensory polyradiculopathy (AISP), and enhance understanding of AISP/chronic immune sensory polyradiculopathy (CISP).Methods:The clinical characteristics, diagnosis and treatment of a domestic AISP patient with NF186 antibody positive admitted to the First Hospital of Shanxi Medical University in December 2021 were summarized, and the previously reported cases of AISP/CISP were systematically reviewed.Results:The patient was a 62-year-old male with acute onset. The clinical manifestations included severe sensory ataxia, increased protein in cerebrospinal fluid, no response to stimulation of the central segment of somatosensory evoked potentials (SEP), normal sensory and motor nerve conduction, and positive serum anti-NF186 antibody (1∶32). After glucocorticoid treatment, the clinical symptoms and SEP were significantly improved. The drug was stopped for 2 months, and there was no recurrence. There were 23 cases of AISP and CISP with complete data reported in the literature (including this patient). The age of onset was (54.7±17.7) years, and the ratio of male to female was 1.88. Three patients with acute onset were classified as AISP. A total of 95.7% (22/23) of patients showed sensory ataxia without limb weakness, 95.0% (19/20) of patients showed prolonged cortical potential latency or even no response, and 95.5% (21/22) of patients showed increased cerebrospinal fluid protein in varying degrees, and nerve root thickening or abnormal enhancement was not common. All 10 patients receiving immunotherapy responded to corticosteroids or intravenous immune globulin. Only 6 AISP/CISP articles reported screening for anti-ganglioside antibodies or Ranvier′s node-paranodal region-related antibodies, and no positive NF186 antibodies were reported. All the 3 patients with AISP had some characteristics of CISP/chronic inflammatory demyelinating polyradiculoneuropathy, and there was no significant difference between AISP and CISP patients in clinical features except the mode of onset.Conclusions:NF186 antibody could cause AISP, which presents as acute onset sensory ataxia. AISP is responsive to glucocorticoid therapy. Except for the mode of onset, AISP and CISP are difficult to distinguish from clinical, electrophysiological, pathological aspects and pathogenic antibodies, so they may be two different manifestations of the same disease.

Objective To investigate the value of F-actin autoantibodies in the serum of patients with systemic lupus erythematosus (SLE),and to explore the relationships between F-actin autoantibodies and other clinical indicators.Methods ELISA was established to detect serum levels of F-actin autoantibodies in 93 inpatients with SLE from March 2017 to January 2018 (case group,n=93),72 patients with rheumatoid arthritis (RA) (disease control group) and 83 healthy subjects (healthy control group) were included during the same period.The positive rates of F-actin autoantibodies between the case group and the two control group were compared.Clinical data including SLE disease activity index (SLEDAI),immuno-globulin (lg)G,erythrocyte sedimentation rate (ESR),anti-dsDNA,and antinuclear antibody (ANA) of 93 patients with SLE were collected and the correlation analysis between F-actin autoantibodies units was applied respectively.The diagnostic performance of F-actin autoantibodies in SLE was analyzed by using the receiver operating characteristic curve (ROC).T test,Chi-square test and Spearman/Pearson correlation analysis were applied for statistical analysis.Results The serum levels of F-actin autoantibodies in the SLE case group,disease control group,and healthy control group were (18±13),(12±6),and (11±5) U,respectively,the differences between SLE case group and disease control group,and healthy control group were significant (t=3.163,P=0.001 9;t=4.436,P＜0.01).The positive rates of F-actin autoantibodies were 33％(31/93) in patients with SLE,10％(7/72) in disease control group,and 4％(3/83) in healthy control group.The F-actin autoanti-bodies units in SLE were correlated with SLEDAI,IgG,ESR,anti-dsDNA,and ANA (r=0.273 7,P=0.008 3;r=0.558 7,P＜0.01;r=0.419 9,P=0.000 1,r=0.351 4,P=0.001 1,r=0.460 9,P＜0.01),in which F-actin autoantibodies units showed significant correlation with IgG and ANA.In the ROC curve,the area under the curve(AUC) was 0.62 [95％CI(0.54,0.70)],P=0.001 3.which was statistically significant.When the cut-off value of the F-actin autoantibodies was 14.04 U,the Youden's index (YI) was the largest (YI=0.30),and the sen-sitivity for the diagnosis of SLE was 0.77,the specificity was 0.53.Conclusion The positive rate of F-actin autoantibodies in the serum of patients with SLE is higher than that of RA and healthy controls,so it has certain diagnostic value for SLE.The F-actin autoantibodies units is correlated with both SLEDAI,ESR,and anti-dsDNA,suggesting that F-actin autoantibodies units may be a new biomarker for disease activity assessment of SLE patients.
