Hodgkin's lymphoma:2023 update on treatment

Hodgkin's lymphoma(HL)is a common,malignant hematological tumor of the lymph nodes and lymphatic system,accounting for 10%of all lymphomas.HL comprises 2 main subtypes:classical HL(cHL)and nodular lymphocyte predominant HL.

Effects of Several Factors on Trapping Quantity of Grapholitha molesta Busck by Sex Pheromone

The key application technology for sex pheromone of Grapholitha molesta was studied from the aspects of different hanging heights and orientations,different doses and types of traps through the tests on trapping quantity of G. molesta in fields. The results showed that the trapping effect was enhanced when the hanging height was increased,and the trapping effect was the best in west direction. The trapping effect was enhanced when the dosage was increased. When it was up to 6 lures,the trapping effect was the best with 38. 75 head / trap; the next was 2 lures with 31. 00 head / trap. All types of traps had trapping ability to G. molesta,among which triangle trapper was the best,followed by self-made bottle trap. Their trapping effects were 138. 75 and 100. 25 head / trap,respectively.

Occurrence and Pollution-free Control of Apolygus lucorum in Winter Jujube

In recent years,Apolygus lucorum has become the main pest of winter jujube. It sucks juice of young parts of winter jujube and causes falling of buds and flowers,leaf perforations,deformities and fall-off of fruits,leading to serious economic loss. Considering the occurrence characteristics and control problems, the distribution,occurrence regularity,damage characteristics and outbreak reasons of A. lucorum are overviewed and analyzed in this paper,and the pollution-free control measures are also put forward.

Effects of Straw Returning and Chemical Control on Occurrence Quantity of Athetis lepigone Moschler in Summer Maize Fields

Athetis lepigone Moschler is a new kind of insect pest occurring in summer corn production areas. By investigation,it was found especially serious in straw returning fields. In this paper,its damage status was investigated in straw returning and chemical controlled fields,respectively. The results showed that the rate of damaged plants was 82% and the maximum pest number per 100 plants was 88 heads in the straw returning fields without chemical control. The application of herbicides and pesticides had no significant effects on occurrence quantity and damage rate,but the pest number per 100 plants decreased a little compared to the fields without chemical control. In the summer maize fields without straw returning,the application of herbicides and pesticides could significantly decrease the damage of Athetis lepigone,the rate of damaged plants was 20% ,and the pest number per 100 plants was 6.

CRISPR/Cas9-mediated editing of GmTAP1 confers enhanced resistance to Phytophthora sojae in soybean

Soybean(Glycine max) is an economically important oilbearing crop that is widely planted worldwide(Babu et al.,2017). Many diseases seriously limit soybean yield. Soybean root rot disease, one of the most destructive soybean diseases, occurs throughout the growth period, resulting in considerable yield losses(Kamoun et al., 2015).

Distributed Secondary Control Strategy Based on Q-learning and Pinning Control for Droop-controlled Microgrids

A distributed secondary control(DSC) strategy that combines Q-learning and pinning control is originally proposed to achieve a fully optimal DSC for droop-controlled microgrids(MGs). It takes advantages of cross-fusion of the two algorithms to realize the high efficiency and self-adaptive control in MGs. It has the following advantages. Firstly, it adopts the advantages of reinforcement learning in autonomous learning control and intelligent decision-making, driving the action value of pinning control for feedback adaptive correction. Secondly, only a small part of points selected as pinned points needs to be controlled and pre-learned, hence the actual control problem is transformed into a synchronous tracking problem and the installation number of controllers is further reduced.Thirdly, the pinning matrix can be modified to adapt to plugand-play operation under the distributed control architecture.Finally, the effectiveness and versatility of the proposed strategy are demonstrated with a typical droop-controlled MG model.

When and How to Adjust Non-Pharmacological Interventions Concurrent with Booster Vaccinations Against COVID-19—Guangdong,China,2022

Introduction:With the large-scale roll-out of the coronavirus disease 2019(COVID-19)booster vaccination effort(a vaccine dose given 6 months after completing primary vaccination)in China,we explore when and how China could lift non-pharmacological interventions(NPIs)against COVID-19 in 2022.Methods:Using a modified susceptible-infectiousrecovered(SIR)mathematical model,we projected the COVID-19 epidemic situation and required medical resources in Guangdong Province,China.Results:If the number of people entering from overseas recovers to 20%of the number in 2019,the epidemic in 2022 could be controlled at a low level by a containment(215 local cases)or suppression strategy(1,397 local cases).A mitigation strategy would lead to 21,722 local cases.A coexistence strategy would lead to a large epidemic with 6,850,083 local cases that would overwhelm Guangdong’s medical system.With 50%or 100%recovery of the 2019 level of travelers from overseas,the epidemic could also be controlled with containment or suppression,but enormous resources,including more hotel rooms for border quarantine,will be required.However,coexistence would lead to an uncontrollable epidemic with 12,922,032 local cases.Discussion:With booster vaccinations,the number of travelers from overseas could increase slightly in 2022,but a suppression strategy would need to be maintained to ensure a controllable epidemic.
