Abstract
Ten new salicyloid derivatives, namely vaccinols J-S (1-10), along with five known compounds (11-15) were isolated from Pestalotiopsis vaccinii (cgmcc3.9199) endogenous with the mangrove plant Kandelia candel (L.) Druce (Rhizophoraceae). Their structures including absolute configurations were established on the basis of spectroscopic analysis, optical rotation, CD spectra, quantum ECD calculations. To the best of our knowledge, vaccinol J (1) is the first example of salicyloid derivatives containing 2-methylfuran moiety. All of the new compounds were tested for their anti-enterovirus 7l (EV71) and cytotoxic activities. Among them, vaccinol J (1) exhibited in vitro anti-EV71 with IC50 value of 30.7μM (IC50 177.0μM for the positive control ribavirin).

Abstract
Objective: To evaluate the efficacy of cuffed tracheostomy tube with inner cannula for the treatment of intractable aspiration after partial laryngectomy. Methods: From May 2010 to June 2015, 15 patients with intractable aspiration after partial laryngectomy of laryngeal and hypopharyngeal carcinoma were enrolled. Cuffed tracheostomy tube with inner cannula was used in the 15 patients for treatment of intractable aspiration. The patients and their family were trained to manage the cuffed tracheostomy tube with inner cannula and to eat since the 14th day after surgery. Cuff was initially inflated with 10 ml air and then deflated of 0.5 ml air every 2-3 days. Until the inflation of cuff was no longer required, the cuffed tracheostomy tube was replaced by metal tracheostomy tube. The patients' swallowing function and aspiration were evaluated 6 months after treatment. Results: The 15 cases with intractable aspiration were treated with cuffed tracheostomy tube with inner cannula and after 2-3 months, 14 of them replaced the cuffed tracheostomy tubes with inner cannula by metal tracheostomy tubes and recovered oral eating, and tracheostomy tubes were no longer required for 12 of 14 patients in following 3-6 months, showing a total decannulation rate of 80% in the patients with refractory aspiration. Conclusion: It was safe and effective to treat aspiration after laryngeal and hypopharyngeal surgery with cuffed tracheostomy tube with inner cannula.

Abstract
This work was undertaken to explore the effects of platycodin D, a triterpenoid saponin from Platycodon grandiflorum, on the growth and invasiveness of human oral squamous cell carcinoma (OSCC). Platycodin D caused a significant, concentration-dependent inhibition of cell viability and induced significant apoptosis in OSCC cells. Moreover, platycodin D significantly inhibited OSCC cell invasion. At the molecular level, platycodin D increased the amounts of IκBα protein and reduced the expression of phosphorylated NF-κB p65, MMP-2, and MMP-9. Ectopic expression of constitutively active NF-κB p65 prevented platycodin D-mediated induction of apoptosis and suppression of invasion in OSCC cells. In vivo studies confirmed that platycodin D retarded the growth of subcutaneous SCC-4 xenograft tumors and reduced phosphorylation of NF-κB p65. Altogether, platycodin D shows inhibitory activity on OSCC growth and invasion through inactivation of the NF-κB pathway and might provide therapeutic benefits in the treatment of OSCC.

Abstract
Objective: To analyze the clinicopathological features and prognosis of patients with small hepatocellular carcinoma. Methods: The clinicopathological and follow-up data of 98 patients with small hepatocellular carcinoma who underwent R0 resection from January 2009 to December 2013 were analyzed retrospectively. Results: All of the patients were followed up. Their postoperative 1-year, 3-year and 5-year overall survival rates were 99.0%, 91.7%, and 76.3%, respectively. Their postoperative median overall survival (OS) period was 52 months. The postoperative progression-free survival rates were 86.7%, 66.2% and 55.0%, respectively, and the median progression-free survival (PFS) period was 43.5 months. The univariate analysis showed that satellite nodules, liver capsule invasion and postoperative recurrence time were associated with OS (P<0.05), and long-term heavy drinking, satellite nodules and liver capsule invasion with PFS (P<0.05). The multivariate analysis indicated that long-term heavy drinking was an independent factor influencing the progression-free survival period of patients with small hepatocellular carcinoma (P=0.003) and postoperative recurrence time and liver capsule invasion were independent factors affecting their overall survival period (P<0.05). Conclusions: The treatment of small hepatocellular carcinoma still concentrates on the active treatment of surgery. It is beneficial to patients to minimize the resection scope of normal liver under the premise of R0 removal of tumor. Postoperative recurrence time of ≤2 years suggests poor prognosis of small hepatocellular carcinoma. Long-term heavy drinking can accelerate the recurrence of small hepatocellular carcinoma.

Abstract
RDX and HMX are widely used energetic materials and they are recognized as environmental contaminants at numerous locations. The present study investigated the biotransformation of RDX and HMX by anaerobic granular sludge under sulfate- and nitrate-enriched conditions. The results showed that RDX and HMX could be transformed by anaerobic granular sludge when nitrate was present. However, the biotransformation of RDX and HMX was negatively influenced, especially with high nitrate concentrations. Sulfate-enriched conditions were more favorable for the removal of ammunition compounds by anaerobic granular sludge than nitrate-enriched conditions. The removal of RDX and HMX under both nitrate- and sulfate-enriched conditions was facilitated by the use of glucose as additional substrate. This knowledge may help identify factors required for rapid removal of RDX and HMX in high-rate bioreactors. These results can also be applied to devise an appropriate and practical biological treatment strategy for explosive contaminated wastewater.

Abstract
Thiopurines (TPDs) are first-line drugs in treating neuromyelitis optica spectrum disorders (NMOSD). Evaluation of thiopurine S-methyltransferase activity (TPMT), a major determinant of TPD toxicity, before TPD treatment using 6-mercaptopurine (6-MP) and 6-thioguanine (6-TG) as substrate was suggested. However, the equivalent of the two substrates in TPMT activity evaluation was unknown, and an alternative substrate was required in TPMT activity evaluation in patients who were already taking 6-MP or 6-TG. Before evaluating the agreement of 6-MP and 6-TG in TPMT activity measurement in patients with NMOSD, the affinity of the two substrates for the active center of TPMT should be established. A computer-based simulation indicated that 6-MP and 6-TG had similar affinities for the two active sites of TPMT. According to the guidelines, an LC-MS/MS method was developed and validated to evaluate the TPMT activity in human erythrocyte hemolysate using 6-MP or 6-TG as substrates via 1 h incubation at 37°C. The method was applied in 81 patients with NMOSD. Evaluated by Bland-Altman plot, 6-methylmercaptopurine and 6-methylthioguanine represented TPMT activities were in agreement with each other. Further studies are warranted to confirm the results.

Abstract
Objective: To investigate the role of "Hong's single-stitch duct to mucosa pancreaticojejunostomy(HSDMP)" in laparoscopic pancreaticoduodenectomy (LPD). Methods: The clinical data including perioperative and short-term outcomes of 51 cases of LPD with HSDMP which performed in Zhejiang Provincial People's Hospital(33 cases) and Frist Clinical Hospital of Jilin University(18 cases) between April and October 2016 were reviewed retrospectively. There were 31 male patients and 20 female patients. The mean age was(59±11)years. Body mass index (BMI) was 18 to 28 kg/m(2) and the average BMI was (23.2±4.4)kg/m(2). Preoperative diagnosis: 18 cases with pancreatic mass, 26 cases with peri-ampullary tumor, 3 cases with intra-ductal papillary mucinous neoplasms, 2 cases with duodenal carcinoma, 2 cases with serous cystadenoma. Results: Fifty-one patients accepted LPD using HSDMP. One patient underwent LPD combined with resection of superior mesentery vein. The mean operation time was (307±69)minutes, the mean diameter of pancreatic duct for reconstruction was (3.1±1.1)mm.The mean operation time for HSDMP was (34±5) minutes, the estimated blood loss was (170±127)ml. Twelve cases(23.5%) had pancreatic fistula according to International Study Group definition, including 9 cases(17.6%) of grade A and 3 cases (5.9%) of grade B. Five cases(9.8%) had delayed gastric empty, 5 cases(9.8%) had bile leakage and 2 cases(3.9%) had pulmonary infection postoperative.All these complications were treated by non-surgical strategies. One patient(2.0%) suffered from postoperative intra-abdominal bleeding and recovered after reoperation. Pathologic results showed pancreatic ductal adenocarcinomas in 20 cases(39.2%), non-pancreatic original peri-ampullary tumors in 23 cases(45.1%), intra-ductal papillary mucinous neoplasms in 3 cases(5.9%), duodenal carcinoma in 2 cases(3.9%), serous cystadenoma in 2 cases(3.9%) and neuroendocrine tumors in one case(2.0%). Conclusions: HSDMP could not only reduce the incidence of clinical pancreatic fistula, but also save operation time. It is a feasible and safe method for pancreaticojejunostomy.

Abstract
The progress of gene detection technologies represented by next generation sequencing (NGS) and digital PCR laid a foundation for studies of circulating tumor DNA (ctDNA) in breast cancer. In 2014, the NGS workgroup organized by the College of American Pathologists (CAP) published the College of American Pathologists' Laboratory Standards for Next-Generation Sequencing Clinical Tests, which provides a blueprint for the standardization of gene testing. In 2015, the Guidelines for Diagnostic Next-generation Sequencing published by the European Society of Human Genetics claimed that NGS is unacceptable in clinical practice before studies guided by guidelines are approved. Although existing studies show the benefits of ctDNA testing in disease monitoring and prognosis analyzing, we have a ways to go to normalize the procedure and build strict detection criteria.

Abstract
Objective: To observe the therapeutic response of radiosynovectomy with p-32 colloid on hemophilic arthropathy, and to assess the effects of radiosynovectomy with Denver Score on hemophilic arthritis staging. Methods: Radiosynovectomy with p-32 colloid was performed on 326 hemophilic arthritis patients (405 joints) , and recorded bleeding before and after treatment. The MRI performance of 102 joints was evaluated by using Denver scoring system, then was divided into 0-6 and 7-10 groups. Finally, the differences between 2 groups were analyzed. Results: Average pain score of all hemophilic arthritis patients at 6 months, 1, 2 and 3 years post treatment decreased from 3.2±2.4 (n=326) to 1.2±0.6 (n=285, P=0.021) , 1.7±0.5 (n=242, P=0.032) , 2.1±1.1 (n=212, P=0.030) and 2.2±1.6 (n=176, P=0.037) , respectively. The frequency of bleeding in 405 joints at 1, 2 and 3 years post treatment decreased from 15.1±3.6 to 2.1±0.7, 4.3±0.6, and 4.8±0.8 times per year (P<0.01) , respectively; Meanwhile, the proportions of significantly ameliorated joints' activities were observed as of 68.50% (248/362) , 58.39% (181/310) , 55.67% (162/239) and 42.61% (75/176) , respectively. The frequencies of haemarthrosis at 1 and 2 years post treatment in patients with 0-6 Denver Score (45 target joints) reduced from 13.0±1.9 to 1.3±0.6 (P=0.002) and 3.1±0.9 (P=0.009) times per year, respectively, which also decreased in 7-10 group (57 target joints) from 16.6±2.1 to 3.1±0.9 (P=0.008) and 5.7±1.1 (P=0.004) times per year, respectively. There was no statistical difference between 0-6 and 7-10 groups before treatment in the terms of haemarthrosis frequency (P=0.773) . However, 7-10 group had higher haemarthrosis frequency at 1 and 2 years post treatment compare with 0-6 group (P=0.028 and 0.042, respectively) . Synovial volumes in 29 joints reduced after 6 month when compared with baseline [ (2 362.15±32.41) mm(3) vs (3 012.40±39.78) mm(3), t=7.621, P<0.001]. Conclusion: Radiosynovectomy with p-32 colloid on haemophilic synovitis was a safe and effective procedure. The patients with Denver Score of 0-7 had lower frequency of haemarthrosis.

Abstract
OBJECTIVE To estimate the prevalence of anemia in urban community dwelling elderly population. METHODS This study was a cross-sectional survey of prevalence of anemia in randomly selected community dwelling residents aged over 65 years in Beijing. Anemia was defined as hemoglobin concentration less than 130 g/L in men and 120 g/L in women. RESULTS The hemoglobin concentration was (135.65±14.48) g/L in total of 1 947 eligible participants and was much higher in men than in women [(142.56±15.56) g/L vs (130.95±11.53) g/L, P<0.001]. There were 288 (14.8%) patients with anemia, including 16.3%(129/789) in men and 13.7%(159/1 158) in women. The prevalence of anemia increased significantly with age, which was 7.6% in 65-69 years, 10.8% in 70-74 years, 18.8% in 75-79 years and 24.1% over 80 years (P<0.001). Two hundred and seventy-nine (96.9%) subjects were mild anemia, 8 (2.8%) moderate, only 1 subject (0.3%) severe. Unexplained anemia was predominant, which accounted for 63.2%. Only 16.7% people were diagnosed as nutritional anemia, renal anemia 5.2%, anemia of chronic disease (ACD) 12.2%. There were 2.4% people with overlapped renal anemia and ACD. Compared with non-anemic subjects, more subjects with unexplained anemia represented macrocytosis (7.1% vs 3.2%, P=0.007). CONCLUSIONS Anemia is a common health problem in urban community dwelling elderly population. Most subjects have anemia with unknown origin. Further investigation is needed to explore the mechanism and related factors of elderly anemia.

Abstract
Eleven diketopiperazine and fumiquinazoline alkaloids (1-11) together with a tetracyclic triterpenoid helvolic acid (12) were obtained from the cultures of a deep-sea derived fungus Aspergillus sp. SCSIO Ind09F01. The structures of these compounds (1-12) were determined mainly by the extensive NMR, ESIMS spectra data and by comparison with previously described compounds. Besides, anti-tuberculosis, cytotoxic, antibacterial, COX-2 inhibitory and antiviral activities of these compounds were evaluated. Gliotoxin (3), 12,13-dihydroxy-fumitremorgin C (11) and helvolic acid (12) exhibited very strong anti-tuberculosis activity towards Mycobacterium tuberculosis with the prominent MIC50 values of <0.03, 2.41 and 0.894 μM, respectively, which was here reported for the first time. Meanwhile gliotoxin also displayed significant selective cytotoxicities against K562, A549 and Huh-7 cell lines with the IC50 values of 0.191, 0.015 and 95.4 μM, respectively.
