Oxidative stress due to aberrant metabolism is considered as a crucial contributor to diabetes and its complications. Hyperglycemia and hyperlipemia boost excessive reactive oxygen species generation by elevated mitochondrial respiration, increased nicotinamide adenine dinucleotide phosphate oxidase activity, and enhanced pro-oxidative processes, including protein kinase C pathways, hexosamine, polyol, and advanced glycation endproducts, which exacerbate oxidative stress. Oxidative stress plays a significant role in the onset of diabetes and its associated complications by impairing insulin production, increasing insulin resistance, maintaining hyperglycemic memory, and inducing systemic inflammation. A more profound comprehension of the molecular processes that link oxidative stress to diabetes is crucial to new preventive and therapeutic strategies. Therefore, this review discusses the mechanisms underlying how oxidative stress contributes to diabetes mellitus and its complications. We also summarize the current approaches for prevention and treatment by targeting the oxidative stress pathways in diabetes.

This study identified six novel azaphilones, isochromophilones G-L (1-6), and three novel biosynthetically related congeners (7-9) from Diaporthe sp. SCSIO 41011. The structures and absolute configurations were elucidated through comprehensive spectroscopic analyses combined with experimental and calculated electronic circular dichroism (ECD) spectra. Significantly, three highly oxygenated azaphilones contain an acetyl group at the terminal chain (4) or linear conjugated polyenoid moieties (5 and 6), which occur infrequently in the azaphilone family. Additionally, several compounds demonstrated inhibition of lipopolysaccharide (LPS)-induced nuclear factor kappa-B (NF-κB) activation in RAW 264.7 macrophages at 20 μmol·L-1. The novel compound (1) effectively inhibited receptor activator of NF-κB ligand (RANKL)-induced osteoclast differentiation without exhibiting cytotoxicity in bone marrow and RAW 264.7 macrophages, indicating its potential as a promising lead compound for osteolytic disease treatment. This research presents the first documented evidence of azaphilone derivatives as inhibitors of RANKL-induced osteoclastogenesis.

OBJECTIVE To summarize and analyze the profile of the implementation of pharmaceutical service by community pharmacists for patients with chronic diseases in China. METHODS Literature was searched from CNKI, Wanfang database, PubMed (Medline), Embase, and Scopus to collect studies about community pharmacists providing pharmaceutical services for patients with chronic diseases. The ways and contents of the implementation of pharmaceutical services for chronic diseases by community pharmacists were summarized descriptively. RESULTS A total of 75 studies were included, involving 49 trial studies and 26 cross-sectional studies. The study sites were mainly located in the developed regions of China, and the types of disease involved in the studies were mainly diabetes mellitus (n=30) and hypertension (n=28); most studies used the following indexes to evaluate pharmaceutical services, such as changes in disease symptoms and related indicators(n=35), improvement of patient compliance(n=34), and the occurrence of adverse drug reactions (irrational drug use) (n=25). The pharmaceutical service provided by community pharmacists included medication education (84.0%), monitoring and follow-up (64.0%), and identifying and solving medication-related problems (58.7%). Thirty-eight studies mentioned that pharmaceutical services were achieved through teamwork, 16 of which mentioned healthcare alliances. A few studies investigated stratified healthcare systems (n=15) and internet-based pharmaceutical services (n=10). CONCLUSIONS In China, pharmaceutical services provided by community pharmacies for patients with chronic diseases are still mainly confined to economically developed areas, and the scope of services is limited to a few diseases and basic pharmaceutical practices. In the future, the implementation of precise pharmaceutical services for different diseases and patients’ disease status, the establishment of medical alliances, and the development of internet-based pharmaceutical services should become the focus of pharmaceutical services.

Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chinese Trauma Surgeon Association organized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries. Eleven questions regarding the use of VSD in abdominal surgeries were addressed: (1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions? (2) Can VSD be preventively used for a high-risk abdominal incision with primary suture? (3) Can VSD be used in severely contaminated/infected abdominal surgical sites? (4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome? (5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage? (6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula? (7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess? (8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects? (9) Does VSD increase the risk of bleeding? (10) Does VSD increase the risk of intestinal wall injury? (11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.

Fifty percent of the deaths caused by severe trauma occur within 1 h after injury. With the concepts of "golden 1 h" and "platinum 10 min", the professionals in the field of emergency trauma treatment have agreed on the necessity of establishing a rapid and efficient trauma rescue system. However, due to the size of the hospital, the population in the neighborhood, the local economic conditions and geographical features, how to establish an optimal trauma rescue system remains an issue. In this paper, we introduced our experiences in a county-level hospital located in middle-and high-income areas.

Objective To investigate the expressions of FAT10 and p53 mutant in gastric cancer tissues and their relations. Methods Immunohistochemistry and RT-PCR were used to detect the expressions of FAT10 and p53 in gastric cancer tissues (n=62), para-cancerous tissues (2-5 cm apart from cancer, n=62), and normal gastric tissues (7>5 cm apart from cancer, n=62). The association of FAT10 with p53 and clinical outcomes were analyzed by Spearman and Pearson correlation. Results The immunohistochemistry examination showed that expressions of FAT10 [51.61%(32/62)] and p53 [45.16% (28/62)] were significantly higher in cancerous tissues than in para-cancerous tissues [12.90%(8/62) and 14.51% (9/62), χ2=21.26 and 20.69, P<0.01] and normal tissues [6.45% (4/62) and 9.68% (6/62), χ2=13.91 and 19.61, P<0.01]. Overexpressions of FAT10 protein and mRNA in cancerous tissues were closely related to lymph node metastasis and TNM staging (both P value<0.05). There was a positive correlation between FAT10 and p53 in protein and mRNA expressions (protein r=0. 865, P<0.05; mRNA r=0.761, P< 0.01). Those with positive expression of FAT10 had lower survival rate compared to those with negative expression (P<0.05). Conclusions The positive relation between over-expression of FAT10 and p53 implicates that both are involved in the gastric carcinogenesis, and FAT10 is a novel gastric cancer marker with prognostic significance.

Objective To evaluate the clinical value of endoscopically nasojejunal feeding tube placement (ENFTP) for nutritional support in patients with severe acute pancreatitis (SAP). Methods Those SAP patients who treated with ENFTP (n= 47) or with total parenteral nutrition (TPN) (n=50) were retrospectively analyzed for laboratory parameters before and 1,2 and 4 weeks after nutrition support. Outcomes in the two groups were compared with respect to complications,mortality, duration of feeding, feeding costs,mechanical ventilation time and length of ICU or hospital stay. Results Four weeks after nutrition sypport, the hemoglobin and albumin were increased in ENFTP group as compared to TPN groups (P < 0. 05), while the blood sugar was decreased significant in ENFTP group than in TPN group (P<0.05). The incidence of peripancreatic or biliary infection and catheter-related infection were lower in ENFTP group than in TPN group. Duration of feeding and hospital stay were shorter, and nutrition cost was lower in ENFTP group (P<0.05). In addition, the APACHE Ⅱ score was significantly improved in ENFTP group(P<0.05). Conclusion ENFTP seems to be safe and less expensive in treatment of patients with acute pancreatitis.
