Objective To measure and define the distribution of left gastric lymph nodes.Meth- ods From Jan.2004 to Apr.2005,silver clips were set around the root of the left gastric artery in 124 pa- tients with esophageal and gastric cardia carcinoma,X-ray films at 0?and 90?simulator gantry in the radio- therapeutic position were taken.Then,the data of the superior,lower,left,right,anterior and posterior bor- der in each patient was recorded.With SAS 8.02 software,data of minimum area which covered the left gas- tric lymph node in different incidences were obtained.Results According to the analysis of Shapiro- Wilk,Kolmogorov-Smimov,Cramer-von Mises and Anderson-Darling tests,each border was of normal distri- bution,with equal frequency in the male and female,despite the actual results in different genders.Pearson Correlation Coefficients analysis did not suggest a significant relationship between the border and height, weight and size of vertebrae,which formed the minimum area covering the left gastric area at frequency of 100%,95%,90% and 85%,which were drawn out through the calculation.Conclusions Aiming at completely identifying the normal distribution of the left gastric lymph node,more patients are required to be in the pool.For the time being,location in the left gastric area can be obtained from details of the results in the present study.

OBJECTIVETo shorten the duration of seed germinating, improve seed emergence and eventurally to establish a practical method for seeding of Paris polyphylla var. yunnanensis seed.

METHODTo study the effect of some factors (temperature, sowing time, covering-soil depth, plastic film ) on seed emergence of P. polyphylla var. yunnanensis.

RESULTThe most suitable temperature for embryonic post-maturity and seed germinating is 18-20 degrees C. Paris seed could emerge in April when it was transfer to a low temperature 0-10 degrees C for 2-4 months after being treated under 18-20 degrees C for 3-4 months. For seed emergence, the best sowing time was before April. The suitable soil depth was about 1 cm. It is a better way to cover the seedling bed with black plastic film for improving the emergence percentage.

CONCLUSIONAbove results provide seedling techniques of P. polyphylla var. yunnanensis.

We reported the discovery of six novel coumarins, toddasirins A-F (1-6), each endowed with modified isoprenyl or geranyl side chains, derived from the roots of Toddalia asiatica. Comprehensive structural elucidation was achieved through multispectroscopic analyses, single-crystal X-ray diffraction experiments, and advanced quantum mechanical electronic circular dichroism (ECD) calculations. Furthermore, the anti-inflammatory activity of these compounds was assessed. Notably, compounds 1-3 and 6 demonstrated notable inhibitory effects on nitric oxide (NO) production in lipopolysaccharide (LPS)-induced RAW 264.7 cells, with 50% inhibitory concentration (IC₅₀) values of 3.22, 4.78, 8.90, and 4.31 μmol·L^-1, respectively.

Background: Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients. Main recommendations: 1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control. Changes in management: The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.
