Objective: To evaluate the 4-year clinical outcomes of patients following Firesorb bioresorbable scaffold (BRS) implantation. Methods: The study reported the 4-year follow-up results of the FUTURE I study. FUTURE I was a prospective, single-center, open-label, first-in-man study which evaluated the feasibility, preliminary safety, and efficacy of Firesorb stent in the treatment of coronary artery stenosis. A total of 45 patients with single de novo lesions in native coronary arteries ,who hospitalized in Fuwai Hospital from January to March 2016 were enrolled. After successfully stent implantation these patients were randomized in a 2∶1 ratio into cohort 1 (n=30) or cohort 2 (n=15). The patients in cohort 1 underwent angiographic, IVUS or OCT examination at 6 months and 2 years; and cohort 2 underwent angiographic, IVUS or OCT at 1 and 3 years. All patients underwent clinical follow-up at 1, 6 months and 1 year and annually thereafter up to 5 years. The primary endpoint was target lesion failure (TLF, including cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization). Secondary endpoints included patient-oriented composite endpoint (PoCE, defined as composite of all death, all miocardial infarction, or any revascularization). Results: A total of 45 patients were enrolled and implanted with Firesorb BRS, including 35 males (77.8%), and the age was (54.4±9.3) years. At 4 years, 10 patients in cohort 1 were reexamined by coronary angiography and OCT examination. Among them, 2 patients' stents were completely degraded and absorbed. Compared with the OCT images of the other 8 patients in cohort 2 at 3 years, the degree of stent degradation was increased, and no stent adherence was found. The 4-year clinical follow-up rate was 100%. In 4-year clinical following up, 2 patients suffered PoCE (4.4%): 1 patient underwent non-target vessel revascularization the day after index procedure and target vessel revascularization (Non-target lesion revascularization) at 2-year imaging follow-up; the other patient underwent target lesion revascularization during imaging follow-up at 4 years but not due to ischemic driven. There was no scaffold thrombosis or TLF events through 4 years. Conclusions: Four years after the implantation, complete degradation and absorption of the Firsorb stent are evidenced in some patients. Firesorb stent is feasible and effective in the treatment of patients with non-complex coronary lesions.

PURPOSE: The purpose of this study was to identify novel plasma biomarkers for distinguishing nasopharyngeal carcinoma (NPC) patients from healthy individuals who have positive Epstein-Barr virus (EBV) viral capsid antigen (VCA-IgA). MATERIALS AND METHODS: One hundred seventy-four plasma cytokines were analyzed by a Cytokine Array in eight healthy individuals with positive EBV VCA-IgA and eight patients with NPC. Real-time polymerase chain reaction, Western blotting, enzyme-linked immunosorbent assay (ELISA), and immunohistochemistry were employed to detect the expression levels of macrophage migration inhibitory factor (MIF) and CC chemokine ligand 3 (CCL3) in NPC cell lines and tumor tissues. Plasma MIF and CCL3 were measured by ELISA in 138 NPC patients, 127 EBV VCA-IgA negative (VN) and 100 EBV VCA-IgA positive healthy donors (VP). Plasma EBV VCA-IgA was determined by immunoenzymatic techniques. RESULTS: Thirty-four of the 174 cytokines varied significantly between the VP and NPC group. Plasma MIF and CCL3 were significantly elevated in NPC patients compared with VN and VP. Combination of MIF and CCL3 could be used for the differential diagnosis of NPC from VN cohort (area under the curve [AUC], 0.913; sensitivity, 90.00%; specificity, 80.30%), and combination of MIF, CCL3, and VCA-IgA could be used for the differential diagnosis of NPC from VP cohort (AUC, 0.920; sensitivity, 90.00%; specificity, 84.00%), from (VN+VP) cohort (AUC, 0.961; sensitivity, 90.00%; specificity, 92.00%). Overexpressions of MIF and CCL3 were observed in NPC plasma, NPC cell lines and NPC tissues. CONCLUSION: Plasma MIF, CCL3, and VCA-IgA combination significantly improves the diagnostic specificity of NPC in high-risk individuals.

BACKGROUND: In the era of precision medicine, chemotherapy is still considered the cornerstone of treatment for lung cancer patients without gene mutations. How to reduce the toxicity and increase the efficiency of chemotherapy is worth exploring. This study aimed to investigate the curative effects and safety of hyperthermia combined with chemotherapy (HCT) for advanced patients with non-small cell lung cancer (NSCLC), especially those with malignant pleural effusion. METHODS: We retrospectively evaluated medical records of 93 patients with advanced NSCLC (stage IIIB-IV) from March 2011 to January 2014. The patients were divided into HCT and chemotherapy (CT) groups. The HCT group was treated with gemcitabine and cisplatin (GP) regimen combined with regional radiofrequency deep hyperthermia, while the CT group was treated with GP regimen only. Those with malignant pleural effusion extra underwent thoracentesis and intrapleural injection chemotherapy combined with hyperthermic or not. Clinical treatment results and adverse reactions were compared and analyzed after treatment. SPSS 19.0 software (SPSS Inc., USA) was used for statistical data processing. P values less than 0.05 were accepted to be statistically significant. RESULTS: Among the 93 patients, HCT group included 48 patients (16 patients with malignant pleural effusion), CT group included 45 patients (10 patients with malignant pleural effusion). There was no significant difference between the two groups in patient characteristics. The overall response rate (ORR) of pleural effusions was much better in HCT group than that in CT group (81.2% vs. 40.0%, P = 0.046). The patients in HCT group had lower incidence rate of weakness (12.5% vs. 46.7%, χ = 13.16, P < 0.001) and gastrointestinal (25.0% vs. 77.8%, χ = 25.88, P < 0.001) adverse reactions than that in CT group. The objective tumor response and survival showed no significant differences. CONCLUSIONS Hyperthermia combined with chemotherapy might lead to the development of better therapeutic strategy for advanced NSCLC with malignant pleural effusion patients. Also, it could greatly reduce the chemotherapy toxic effects in the incidence of weakness and gastrointestinal adverse reactions in advanced NSCLC patients.

OBJECTIVEThis study aimed to investigate the expression pattern and function of Nuclear receptor subfamily 2 group E member 1 (Nr2e1) in retinoic acid (RA)-induced brain abnormality.

METHODSThe mouse model of brain abnormality was established by administering 28 mg/kg RA, and neural stem cells (NSCs) were isolated from the mouse embryo and cultured in vitro. Nr2e1 expression was detected by whole mount in situ hybridization, RT-PCR, and Western blotting. Nr2e1 function was determined by transducing Nr2e1 shRNA into NSCs, and the effect on the sonic hedgehog (Shh) signaling pathway was assessed in the cells. In addition, the regulation of Nr2e1 expression by RA was also determined in vitro.

RESULTSNr2e1 expression was significantly downregulated in the brain and NSCs of RA-treated mouse embryos, and knockdown of Nr2e1 affected the proliferation of NSCs in vitro. In addition, a similar expression pattern of Nr2e1 and RA receptor (RAR) α was observed after treatment of NSCs with different concentrations of RA.

CONCLUSIONOur study demonstrated that Nr2e1 could be regulated by RA, which would aid a better understanding of the mechanism underlying RA-induced brain abnormality.

PURPOSE: Choledochoduodenal fistula (CDF) is an extremely rare condition even in the most populous nations. However, diagnostic tools are inadequate for the young surgeon to be made aware of such a rare condition before surgery. Hence, basic understanding of the epidemiology, etiology, and management for this unusual but discoverable condition are necessary and essential. METHODS: The exclusive case reports of CDF, which were published from 1983 to 2014 concerning mainland Chinese people, were performed to review the epidemiology, etiology, and management. RESULTS: A total of 728 cases were incorporated into this review among 48 papers. More than half of the CDF cases were female (416) with an average age of 57.3 years. CDF was usually caused by cholelithiasis (573 of 728). Epigastric pain (589 of 728) and cholangitis (395 of 728) were the most common symptoms of CDF. CDF was usually detected and confirmed by endoscopic retrograde cholangiopancreatography (ERCP) (475 of 728) in Mainland China. The fistulas larger than 1 cm (82 of 654) were recommended for surgical biliary reconstruction. Fistulas between 0.5 cm and 1.0 cm (467 of 654) which were followed frequently by cholangitis attacks also required surgery; the rest were recommended to have stone removal and/or the application of an effective biliary drainage. Fistulas less than 0.5 cm (105 of 654) were usually received conservative therapy. CONCLUSION: CDF should be considered in differential diagnosis of recurrent epigastric pain and cholangitis. A possible ERCP should be arranged to investigate carefully. Depending on the size of fistula and clinical presentation, different programs for CDF are indicated, ranging from drug therapy to choledochojejunostomy.

OBJECTIVETo observe the efficacy and safety of Danlong Oral Liquid (DOL) combined Western medicine (WM) in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.

METHODSTotally 480 mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset were randomly assigned to two groups in the ratio 3:1, the treatment group (360 cases) and the control group (120 cases). All patients received basic WM treatment. Patients in the treatment group took DOL, 10 mL each time, 3 times per day for 7 days in total, while those in the control group took Kechuanning Oral Liquid (KOL) , 10 mL each time, 3 times per day for 7 days in total. Efficacy for asthma symptoms, lung functions and scores of TCM syndrome and/or main symptoms were evaluated.

RESULTSThe percentage of clinical control and significant effectiveness of asthma symptoms in the treatment group was significantly higher than that of the control group (77.36% vs 56.07%, P < 0.01). The percentage of clinical control and significant effectiveness of lung functions in the treatment group was significantly higher than that of the control group (74.28% vs 50.00%, P < 0.01). The anterior-posterior difference in scores of TCM syndrome was significantly superior in the treatment group than in the control group (-11.26 ± 4.70 vs -9.21 ± 5.09, P < 0.01). The anterior-posterior difference in scores of main symptoms was significantly better in the treatment group than in the control group (-6.58 ± 3.08 vs -5.16 ± 3.45, P < 0.01). The incidence of adverse reactions was significantly lower in the treatment group than in the control group [1.73% (6/346 cases) vs 10.17% (12/118 cases) , P < 0.05].

CONCLUSIONDOL combined WM was superior to KOL in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.

OBJECTIVETo explore the pattern of lymph node metastasis and evaluate the modes and extent of mediastinal lymph node dissection in patients with ≤ 3 cm, clinical stage I primary non-small cell lung cancer (NSCLC).

METHODSData of 270 eligible patients who underwent pulmonary resection with systematic lymph node dissection in our hospital between March 2012 and August 2013 were retrospectively analyzed in order to investigate the relationship between the clinicopathological features and lymph node metastatic patterns. Patients with multiple primary carcinomas or non-primary pulmonary malignancies and those who received any chemotherapy or radiotherapy or did not undergo systematic nodal dissection were excluded. The criteria of systematic nodal dissection included the removal of at least six lymph nodes from at least three mediastinal stations, one of which must be subcarinal. The data were analyzed and compared using Chi-square test.

RESULTSThe postoperative morbidity rate was 14.8% and no death occurred in this series. The imaging findings showed 34 cases of pure ground glass opacity lesions, 47 partial solid nodules, and 189 solid nodules. Apart from 34 p-GGO lesions, among the other 236 cases, ≤ 1 cm lesions were in 22 cases, 1 cm- ≤ 2 cm lesions in 138 cases, and >2 cm- ≤ 3 cm lesions in 76 cases based on radiologic findings. The pathological types included adenocarcinoma (n = 245), squamous cell carcinoma (n = 18) and other rare types (n = 7). The overall lymph node metastasis rate was 18.9% (51/270), and the incidence of lymph node involvement was 0(0/34) in cancers with p-GGO, 2.1% (1/47) in mixed solid nodules, 26.5% (50/189) in solid nodules, 18.2% (4/22) in nodules ≤ 1 cm, 14.5% (20/138) in 1 cm < nodules ≤ 2 cm, and 35.5% (27/76) in 2 cm < nodules ≤ 3 cm. The metastasis rates of non-specific tumor-draining region lymph nodes detected in the patients with positive and negative lobe-specific lymph node involvement were 20.0%-50.0% vs. 0-2.9% (P < 0.001).

CONCLUSIONSUsually NSCLC with p-GGO nodules has no lymph node metastasis, therefore, systematic nodal dissection may be not necessary. The larger the tumor size is, the higher the lymph node metastatic rate is for mixed or solid nodules. Intraoperative frozen-section examination of the lobe-specific lymph nodes should be performed routinely in patients with ≤ 2 cm stage I NSCLC, and systematic nodal dissection should be done if positive, but it may be not necessary if negative. However, the effectiveness of the systematic selective lymph node dissection still needs to be further confirmed.

BACKGROUNDPoly (ADP-ribose) polymerase (PARP) plays an important role in cell survival and death. However, the mechanisms involved are not fully understood. Therefore, we investigated the effect of inhibition of PARP on acute myocardial infarction (AMI) at different time points in rats.

METHODSAMI was induced in rats by ligating the left anterior descending coronary artery. One group received 3-aminobenzamide (3-AB, a kind of PARP inhibitor) (30 mg/kg) by intraperitoneal injection. The changes of ultramicrostructure of cardiocytes in infarction region were noted, PARP cleavage was measured by Western blotting, and expressions of protein of PARP and apoptosis inducing factor (AIF) were measured by immunohistochemical staining after treatment with 3-AB for 2 hours, 4 hours, 6 hours, 1 week, 4 weeks and 8 weeks.

RESULTSFew damages to the ultramicrostructure of cardiocytes were observed after treatment with 3-AB. PARP cleavage was detected as early as 4 hours and markedly increased by 6 hours following AMI without 3-AB, but was not found until 6 hours following AMI treated with 3-AB. There were significant differences between 3-AB and AMI groups at the same time points. The expression of PARP was observed gradually increased, but that of AIF was suppressed for 6 hours after treatment of 3-AB, compared with AMI groups in positive cells at the same time points. There was significantly less cleavage of PARP and more PARP expression in 3-AB treated group compared with AMI and control groups at all matched time points.

CONCLUSIONSOur results suggest that 3-AB inhibits degradation of PARP, increases the expression of PARP protein, and suppresses the expression of AIF protein. Inhibition of PARP activity may protect cardiocytes in rats with AMI and reduce apoptosis.
