Wound cleansing is an essential step in skin wound management. It can prevent local infection and optimize healing micro-environment by removing necrotic tissue and foreign matter, reducing microbial load, breaking bacterial biofilm formation and so on. Many randomized controlled trials and meta-analysis abroad have concluded that there is no significant difference in the incidence of wound infection and healing rate between the wounds irrigated with tap water and with sterile normal saline for skin wound cleansing. Considering the current requirements of medical fee policies in China, we recommend the use of tap water instead of saline or other wound cleansing solutions for cleansing skin wounds.

Durio zibethnus is mainly distributed in Southeast Asia. Traditional Chinese medicine believes that durian shells have the effects of clearing heat and purging fire, nourishing yin and moisturizing dryness. Therefore, it is often used as a pharmaceutic food in the Chinese folk to assist treating diseases. At present, the chemical constituents isolated from durian shell include phenolic acids, phenolic glycosides, flavonoids, coumarins, triterpenes, simple glycosides and other compounds. Modern pharmacological studies show that durian shell has many pharmacological activities, such as antioxidant, anti-inflammatory, regulation of glucose and lipid metabolism. The chemical composition and pharmacological effects of durian shells are summarized in order to provide references for the further research and application of durian shell.

Objective To explore the feasibility of the CT image reconstruction of laryngeal cartilage and hyoid bone in adult age estimation using data mining methods. Methods The neck thin slice CT scans of 413 individuals aged 18 to <80 years were collected and divided into test set and train set, randomly. According to grading methods such as TURK et al., all samples were graded comprehensively. The process of thyroid cartilage ossification was divided into 6 stages, the process of cricoid cartilage ossification was divided into 5 stages, and the synosteosis between the greater horn of hyoid and hyoid body was divided into 3 stages. Multiple linear regression model, support vector regression model, and Bayesian ridge regression model were developed for adult age estimation by scikit-learn 0.17 machine learning kit （Python language）. Leave-one-out cross-validation and the test set were used to further evaluate performance of the models. Results All indicators were moderately or poorly associated with age. The model with the highest accuracy in male age estimation was the support vector regression model, with a mean absolute error of 8.67 years, much higher than the other two models. The model with the highest accuracy in female adult age estimation was the support vector regression model, with a mean absolute error of 12.69 years, but its accuracy differences with the other two models had no statistical significance. Conclusion Data mining technology can improve the accuracy of adult age estimation, but the accuracy of adult age estimation based on laryngeal cartilage and hyoid bone is still not satisfactory, so it should be combined with other indicators in practice.

Objective:To evaluate the role of cannabinoid receptor 2 (CB2R) in macrophage pyroptosis induced by lipopolysaccharide (LPS) in mice.Methods:Macrophage line RAW264.7 cells of mice were routinely cultured and divided into 3 groups ( n=18 each) using a random number table method: control group (group C), LPS group and LPS plus CB2R agonist HU308 group (group HU308). Group C received no mediation, LPS at the final concentration of 1 μg/ml was added in the other groups.After incubation for 15 min, HU308 with the final concentration of 10 μmol/L was added in group LPS+ HU308.All groups were then incubated for 6 h. The expression of nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3), caspase-1, caspase-11 and gasdermin D (GSDMD) mRNA was measured by real-time polymerase chain reaction, the expression of NLRP3, caspase-1, caspase-11, GSDMD and C-terminal domain of human GSDMD (GSDMD-C) was detected by Western blot, and the concentrations of interleukin-18 (IL-18) and IL-1β in the supernatant were determined by enzyme-linked immunosorbent assay.GSDMD-C/GSDMD ratio was calculated. Results:Compared with group C, the expression of NLRP3, caspase-1, caspase-11, GSDMD and GSDMD-C was significantly up-regulated, GSDMD-C/GSDMD ratio was increased, and the concentrations of IL-18 and IL-1β in the supernatant were increased in group LPS ( P<0.05). Compared with group LPS, the expression of NLRP3, caspase-1, caspase-11, GSDMD and GSDMD-C was significantly down-regulated, GSDMD-C/GSDMD ratio was decreased, and the concentrations of IL-18 and IL-1β were decreased in group HU308 ( P<0.05). Conclusion:CB2R is involved in macrophage pyroptosis induced by LPS in mice.

OBJECTIVES: To develop a new Chinese medicine (CM)-based drug and to evaluate its safety and effect for suppressing acute respiratory distress syndrome (ARDS) in COVID-19 patients. METHODS: A putative ARDS-suppressing drug Keguan-1 was first developed and then evaluated by a randomized, controlled two-arm trial. The two arms of the trial consist of a control therapy (alpha interferon inhalation, 50 µg twice daily; and lopinavir/ritonavir, 400 and 100 mg twice daily, respectively) and a testing therapy (control therapy plus Keguan-1 19.4 g twice daily) by random number table at 1:1 ratio with 24 cases each group. After 2-week treatment, adverse events, time to fever resolution, ARDS development, and lung injury on newly diagnosed COVID-19 patients were assessed. RESULTS: An analysis of the data from the first 30 participants showed that the control arm and the testing arm did not exhibit any significant differences in terms of adverse events. Based on this result, the study was expanded to include a total of 48 participants (24 cases each arm). The results show that compared with the control arm, the testing arm exhibited a significant improvement in time to fever resolution (P=0.035), and a significant reduction in the development of ARDS (P=0.048). CONCLUSIONS Keguan-1-based integrative therapy was safe and superior to the standard therapy in suppressing the development of ARDS in COVID-19 patients.

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.
