In the COVID-19 epidemic prevention and control work, not only the safety management of in-hospital organ transplantation is facing severe challenges, but also a large number of patients at home after transplantation are in immunosuppressive state, and professional protection management is urgently needed. Since the outbreak of the epidemic, Shulan(Hangzhou)hospital fully identified the risks of transplant patients, established a special team, and formulated and implemented the control management plan for organ transplant patients based on the crisis leadership model. The control management plan has achieved staged results.From January 15 to March 2, 2020, 29 liver transplants and 31 kidney transplants were performed in our hospital. The remote health education of 1 002 patients after liver and kidney transplantation was completed. The goal of " zero infection" was achieved, and the protection management quality indicators were ideal.

OBJECTIVE:
To compare the blood flow in sequential and individual saphenous vein grafts (SVGs) and to analyze the influence of the location of the target vessel in off-pump coronary artery bypass grafting (OPCAB).
METHODS:
A total of 464 SVGs in 412 patients receiving OPCAB were nested into individual SVG (n=206), double (n=241) or triple sequential SVG (n=15), and analyzed.
RESULTS:
The blood flow in double and triple SVGs was significantly higher than in individual SVGs [(43.4±22.5), (43.7±19.2) and (28.9±18.7) mL/min, respectively, P<0.001, P=0.047]. There were no differences between flow in double and triple SVGs (P=0.96). Pulsatility index (PI) of the three groups were similar (2.6±1.2, 2.5±1.6, 2.8±0.9, respectively, P=0.49, P=0.49). In individual SVGs to right coronary artery, the blood flow was higher than in the posterior descending branch (PDA) (P=0.047) and posterior branch of left ventricle (PBLV), the flow-time in systole period was longer than diagonals (P=0.003), obtuse marginal (OM) (P=0.013) and PDA (P=0.002), PI was significantly lower than PDA (P=0.033) and PBLV (P=0.032). The blood flow in individual SVGs to diagonals was significantly lower than in other target vessels except for PBLV (P<0.05). Flow in double SVGs to PDA-PBLV was significantly lower than in PDA-OM.
CONCLUSION
The mean blood flow in double and triple sequential SVGs is about 1.5 times higher than in individual SVGs. Individual, double, and triple SVGs have similar pI. Flow in individual SVGs to diagonals was significantly lower than in other target vessels except for PBLV.

ObjectiveThe effect of inoculation with different organophosphate-resolving bacteria or compound bacteria on the quality of Paris polyphylla var. yunnanensis medicinal materials and rhizosphere soil fertility were studied to provide a reference for the development and application of biological bacterial fertilizer in artificial cultivation of P. polyphylla var. yunnanensis. MethodThe three dominant species of organophosphate-solubilizing bacteria were inoculated separately and in combination in sterilized soil by single-factor indoor pot planting, and no inoculation was used as the control group. The effect of inoculation of organophosphate-solubilizing bacteria on total saponins content in rhizomes of P. polyphylla var. yunnanensis, as well as microbial numbers, enzyme activities and nutrient contents in rhizosphere soil were analyzed. ResultIn the seven treatments inoculated with organophosphate-solubilizing bacteria, the total saponin content in the rhizomes of Paris polyphylla var. yunnanensis was increased by 16.42%, 3.83%, 16.86%, 33.69%, 2.11%, 13.44%, and 28.83%, respectively, compared with the control. Inoculation with organophosphate-solubilizing bacteria increased the number of soil microorganisms to varying degrees, and the effects of S6 and S7 treatments were the most significant. Inoculation with organophosphate-solubilizing bacteria improved the enzyme activity, and the effect of S7 treatment was the most significant. The activities of acid phosphatase, neutral phosphatase, alkaline phosphatase, protease, invertase and catalase were 49.96% and 104.67% , 110.17%, 99.61%, 26.26%, 11.29% higher than those of the control, respectively. Inoculation with organophosphate-solubilizing bacteria reduced the pH of the rhizosphere soil and increased the content of soil available nutrients. Under the S7 treatment, the contents of alkaline hydrolyzable nitrogen, available phosphorus and available potassium in the rhizosphere soil of P. polyphylla var. yunnanensis were 181.46%, 51.64% and 42.62% higher than those of the control, respectively. Correlation analysis showed that there was a significant positive correlation between total saponins and phosphatase activities, a significant positive correlation between soil microorganisms and soil enzyme activities, and a very significant positive correlation between soil nutrients. ConclusionInoculation of different organophosphate-resolving bacteria or compound bacteria can improve the quality and rhizosphere soil fertility of P. polyphylla var. yunnanensis. Among them, the mixed inoculation of three kinds of bacteria and the mixed inoculation of B. mycoides and B. wiedmannii have the best effect.

ObjectiveTo study the effect of organophosphate-solubilizing bacteria and compound bacteria on the photosynthesis and physiological and biochemical characteristics of leaves of Paris polyphylla var. yunnanensis, and to provide a reference for selecting suitable bacterial fertilizers in artificial cultivation of this medicinal species. MethodPot experiment was carried out indoor and the following groups were designed: control (CK), inoculation with Bacillus mycoides (S1), inoculation with B. wiedmannii (S2), inoculation with B. proteolyticus (S3), inoculation with B. mycoides and B. wiedmannii (S4), inoculation with B. mycoides and B. proteolyticus (S5), inoculation with B. wiedmannii and B. proteolyticus (S6), and inoculation with B. mycoides, B. wiedmannii and B. proteolyticus (S7). Then, the growth and development, photosynthesis, and various physiological and biochemical indexes of the leaves of this species were observed. ResultCompared with CK, the treatment groups showed decrease in content of malondialdehyde in the leaves (P<0.05), particularly S7 (content was only about 1/3 that of the CK). The leaf area, photosynthetic parameters, photosynthetic pigment content, soluble sugar content, soluble protein content, and activity of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) in leaves of the treatment groups were all improved. Among them, the leaf area, soluble sugar content, and soluble protein content were the highest in S7, which were 2.8, 2.1, and 2.2 times that of the CK, respectively. SOD activity peaked in S6 (2.9 times higher than that in the CK) and the highest activity of POD and CAT was detected in S5 (1.5 times and 2.1 times, respectively higher than that in the CK). ConclusionInoculation with different organophosphate-solubilizing bacteria or compound bacteria can promote the growth and development of P. polyphylla var. yunnanensis and improve its resistance to stresses. The combination of B. mycoides and B. proteolyticus and the combination of the three achieved the have the best effect. This study provides a reference for the selection of bacterial fertilizers for artificial cultivation of P. polyphylla var. yunnanensis.
