Objective:
To evaluate the minimally invasive splayed incisions in the internal fixation with a conventional calcaneal plate for calcaneal fractures of sanders types Ⅱ and Ⅲ.
Methods:
This prospective study was conducted from May 1st, 2016 to December 1st, 2017 in the 40 patients with calcaneal fracture at Department of Orthopedics, Shanghai Pudong Hospital. Their ages ranged from 23 to 55 years (average, 39.5 years). According to the Sanders classification, 27 fractures were type Ⅱ and 13 type Ⅲ. They were all treated with a conventional calcaneal plate through minimally invasive splayed incisions. The Böhler and Gissane angles, the height, width and length of the affected calcaneus were compared between preoperation, 3 months after operation and the last follow-up; the clinical function of the affected feet was graded using the Maryland foot score; postoperative complications were observed.
Results:
The 40 patients were followed up for an average of 12.5 months (from 11 to 16 months). All the skin incisions healed well with no skin necrosis or wound infection. No injury to the sural nerve occurred. All the fractures healed after an average of 8 weeks (from 7 to 10 weeks). All the patients resumed their routine daily activities and returned to their former work post after an average time of 4.1 months (from 3 to 6 months). At pre-operation, 3 months after operation and the last follow-up, their Böhler angles were respectively 19.2°±6.3°, 30.5°±6.4° and 29.9°±6.5°; their Gissane angles 103.9°±14.8°, 119.3°±5.6° and 119.8°±6.3°; their calcaneal heights (32.5±3.5) mm, (36.8±1.5) mm and (36.5±1.8) mm; their calcaneal widths (36.8±3.4) mm, (33.1±3.8) mm and (33.0±3.2) mm; their lengths (61.4±4.5) mm, (65.5±6.9) mm and (65.5±9.4) mm. In all the patients, the Böhler and Gissane angles and the calcaneal heights and lengths increased significantly while the calcaneal widths decreased significantly at 3 months after operation and the last follow-up (

Objective To compare the prediction of Functional Gait Assessment (FGA) and Berg balance scale (BBS) for fall among community-dwelling older adults aged 75~85 years old. Methods 162 older adults randomly selected from 3 communities in Beijing were evaluated with FGA and BBS. They were divided as fallers and nonfallers according to the history of fall during the last year. Results The scores of FGA and BBS increased significantly in the nonfallers compared with the fallers (P<0.001). The total scores of FGA correlated with the scores of BBS (r=0.723, P<0.001). The total scores of FGA significantly correlated with the scores of items of FGA (P<0.01), except that of walking with eyes closed (P=0.31). According to the Receiver Operating Characteristic (ROC) Curve, the area under the curve was 0.901 for FGA, and 0.872 for BBS. According to the Youden index, the cutoff value of FGA was 19.5, with sensitivity of 85.5% and specificity of 81.2%. The cutoff value of BBS was 48.5, with sensitivity of 78.3% and specificity of 83.3%. Conclusion FGA is more effective than BBS for predicting the fall in community-dwelling older adults, which is more sensitive and similarly specific.

Objective To investigate the diagnosis, treatments for primary hepatic neuroendocrine neoplasm (NEN) and the efficacy.Methods Clinical data of 10 patients with primary hepatic NEN admitted in Hunan People's Hospital from March 2013 to December 2015 were analyzed retrospectively. The informed consents of all patients were obtained and the local ethical committee approval was received. There were 3 males and 7 females, aged 21-65 years old and the median age was 45 years old. According to the WHO classification for digestive system tumor 2010 version, there were 6 cases of neuroendocrine tumor (NET) G2, and 4 cases of neuroendocrine carcinoma (NEC). The clinical data, imaging characteristics, treatment, tumor pathological characteristics and prognosis of the patients were analyzed.Results Right upper abdominal pain was observed in 5 cases, right upper abdominal mass in 1 case, asthenia and anorexia1 in 1 case, and the remaining 3 cases were found with tumor when receiving routine physical examination. For imaging finding, 8 cases were diagnosed as isolated liver mass, and 2 were found with multiple masses in the liver. All of the 10 patients were confirmed by pathological examination, of which 3 were diagnosed by biopsy before operation, and 7 were confirmed with pathology after operation. 6 cases underwent radical resection, 1 case received microwave ablation, 1 underwent liver resection and intravenous chemotherapy pump implantation, 1 received chemotherapy alone and 1 abandoned treatment. To the submission date of this article, 6 cases survived without recurrence, 1 case suffered recurrence 1 month after operation with multiple lymph node metastases in the peritoneum and remained alive. 2 cases died, 1 of which died of no treatment after biopsy, 1 died of multiple distant metastases after 1 period of chemotherapy, and 1 lost follow-up.Conclusions There is no specific clinical manifestations of hepatic NEN. It should be confirmed by pathological examination. Surgical resection is the first choice for treatment. For patients with unresectable mass, TACE, microwave ablation and chemotherapy can be applied.

Pancreatic adenocarcinoma (PAAD) is one of the most lethal malignancies. Although gemcitabine (GEM) is a standard treatment for PAAD, resistance limits its application and therapy. Secoemestrin C (Sec C) is a natural compound from the endophytic fungus Emericella, and its anticancer activity has not been investigated since it was isolated. Our research is the first to indicate that Sec C is a broad-spectrum anticancer agent and could exhibit potently similar anticancer activity both in GEM-resistant and GEM-sensitive PAAD cells. Interestingly, Sec C exerted a rapid growth-inhibiting effect (80% death at 6 h), which might be beneficial for patients who need rapid tumor shrinkage before surgery. Liquid chromatography/mass spectrometry and N-acetyl-l-cysteine (NAC) reverse assays show that Sec C sulfates cysteines to disrupt disulfide-bonds formation in endoplasmic reticulum (ER) proteins to cause protein misfolding, leading to ER stress and disorder of lipid biosynthesis. Microarray data and subsequent assays show that ER stress-mediated ER-associated degradation (ERAD) ubiquitinates and downregulates YAP to enhance ER stress via destruction complex (YAP-Axin-GSK-βTrCP), which also elucidates a unique degrading style for YAP. Potent anticancer activity in GEM-resistant cells and low toxicity make Sec C a promising anti-PAAD candidate.
