The key to performing spreading moxibustion on the Du meridian and the characteristics of its application are investigated. Summer is the time suitable for spreading moxibustion on Du meridian. The performance on Du meridian points has special requirements for every procedure: selecting moxibustion materials, spreading medication, igniting moxa and cleaning moxibustion sores. There are five large characteristics in the clinical application. The first is accumulating heat and focusing on warm-unblocking; the second is regulating both the whole body and local parts; the third is timing the treatment and making adaptations;the fourth is selecting high-quality materials and guarantee the performance;the fifth is focusing on health maintenance and strengthening nursing. Spreading moxibustion on the Du meridian has a wide area of performance, large moxa cones, a long time, sufficient fire power, strong warm-unblocking force, quick and convenient treatment and a remarkable effect. Mastering the key to the performance and the characteristics of the clinical application can further rich acupuncture and moxibustion treatments and give full play to the role of old and traditional moxibustion.

Objective:To explore the clinical characteristics, treatment and prognosis of splenic marginal zone lymphoma.Methods:The clinical data of 51 patients with splenic marginal zone lymphoma who underwent surgical treatment at Department of Hepatobiliary in Peking University People's Hosipital from Dec 2009 to Oct 2022 were retrospectively analyzed.Results:The patients 's average age was 60.5±11.8 years old, and the ratio of male to female rate was about 1:1. As of the last follow-up date of Feb 28, 2023, 8 patients died of the primary lymphoma and 14 patients suffered from disease progression. The 5-year progression free survival rate was 68%, and the overall survival rate was 79%. Univariate analysis showed that age ≥65 years old, decreased preoperative albumin, increased bilirubin level, and increased lactate dehydrogenase bode ill for overall survival time, but none of them were independent risk factors; Age ≥65 years old and diffuse large B cell transformation were independent risk factors.Conclusions:Surgery combined with comprehensive treatment which contained rituximab is currently the main treatment method. Splenectomy remains an important treatment and diagnostic method for patients with obvious symptoms or persistent unrelieved blood count abnormalities and unexplained splenomegaly. Advanced age, elevated bilirubin and lactate dehydrogenase, decreased albumin, and diffuse large B cell transformation, it may indicate poor prognosis.

Objective To investigate the diagnostic value of dynamic-extended focused assessment with sonography for trauma (D-EFAST) in patients with multiple trauma in intensive care unit (ICU). Methods A prospective clinical study was conducted. Eighty patients with multiple trauma admitted to ICU of Anhui Provincial Hospital from September 1st, 2014 to December 31st, 2016 were enrolled. Extended focused assessment with sonography for trauma (E-FAST) check was conducted at first, for those who had positive findings diagnosis was confirmed by immediately CT examination or surgical exploration. If it was negative, the patients received E-FAST every morning for 7 days (defined as D-EFAST), for those with positive findings, immediately CT or surgery was performed to clarify the diagnosis. The final clinical diagnosis was used as the "gold standard" to calculate the diagnostic accordance rate of EFAST and D-EFAST examination technique for pneumothorax, pleural effusion, spleen injury, kidney damage, liver damage, gastrointestinal injury, pericardial effusion, bladder rupture, and pancreatic injury, as well as their sensitivity, specificity, positive predictive value, negative predictive value, accuracy rate, and missed diagnosis rate, and the difference between EFAST and D-EFAST was compared. Results There were 4 patients excluded because of death and abandoning treatment, and finally 76 patients were included in the study. The total sensitivity of E-FAST examination technique for pneumothorax, pleural effusion, spleen injury, liver damage, gastrointestinal injury, pericardial effusion, and bladder rupture was 75.9% (66/87), and the specificity was 98.3% (587/597), the positive predictive value was 86.8% (66/76), and the negative predictive value was 96.5% (587/608), the accuracy rate was 95.5% (653/684), and the rate of missed diagnosis was 24.1% (21/87). The most of the delayed injury in patients with multiple trauma occurred at 2-7 days after injury with incidence of 4.8% (33/684). The diagnostic sensitivity of D-EFAST for delayed injury was 98.3% (118/120), the specificity was 99.8% (563/564), the positive predictive value was 99.2% (118/119), the negative predictive value was 99.6% (563/565), the diagnostic accuracy rate was 99.6% (681/684), and rate of missed diagnosis was 1.7% (2/120). When the final clinical diagnosis was set as the "gold standard", D-EFAST technology for the detection rate was 98.3% (118/120) for patients with multiple trauma on organ injury while the detection rate of E-FAST was 75.9% (66/87), with statistical significant difference (P < 0.01), indicating that D-EFAST was better than E-FAST in check of multiple trauma patients with organ injury. Conclusion Although the E-FAST technology can quickly diagnose the multiple trauma patients and win the rescue time for critical patients, multiple trauma patients injured after 2-7 days prone to delayed damage and are difficult to detect, and D-EFAST can be used to find delayed damage earlier, and reduce the misdiagnosis rate of multiple trauma patients.
