Object To determine the diumal changes of photosynthesis, its relationships with light intensities and temperatures, and the contents of chloroophyll in leaves of Dendrobium candidum Wall. ex. Lindl., D. wilsonii Rolfe and D. hercoglossum Reichb. f. Methods The net photosynthetic rate (NPR) was measured at intervals of 1.5 h during daytimes 7:30—16:30, under the photosynthetic affective rates 0—140 mmol/(m 2?s), and under the temperatures 29.6—38.2 ℃; contents of chlorophyll a and b in leaves were measured. Results NPR, light saturation point and compensation point were low in each of the three Dendrobium L. species. The NPR peaked during 8:00 and 10:00 am, and thereafter decreased rapidly as the temperature and light intensity increased. Content of chlorophyll b was high in the leaves. Conclusion These results indicated that the Dendrobium L. species, which are sciophyte plants, have great adaptations to their growing habitats.

ObjectiveTo investigate the effect of glucose and insulin on the synthesis and secretion of adrenomedullin (ADM) by rat aortas in vitro.MethodsThe rat aortas were cut into pieces and divided into several equal groups. All the groups were incubated in K-H buffers including different levels of glucose,insulin and insulin+glucose for 3 hours,the group incubated in K-H buffer without glucose was used as control. To determine ADM in K-H buffers and tissues using RIA method.ResultsADM levels in insulin groups (100.0 μIU/ml,200.0 μIU/ml) and insulin+glucose groups were higher than that in control (P<0.05),the ADM levels in glucose groups and low level insulin group (20.0 μIU/ml) were not significantly difference compared with the control. ConclusionHigh levels of insulin can stimulate the synthesis and secretion of ADM.

Diffuse large B-cell lymphoma(DLBCL)is a highly invasive malignant lymphoma,and the molecular mechanism of its patho-genesis is not fully understood.Next generation sequencing(NGS)is an increasingly mature gene assay technology,which has been widely applied in recent years to study the genetics of DLBCL.Targeted therapy development has progressed significantly on the basis of these studies,which has made genetic mutations in DLBCL become the new research hotspot.This review summarizes the progress in research on progress-related gene mutations in DLBCL.

Chronic pain is a public health concern of desiderate to be solved, and analgesics is not always successful and may be difficult to tolerate in clinic.Studies have suggested that the development of chronic pain involves alterations in multiple brain regions.Central modulation mechanisms, especially those soliciting the prefrontal cortex and its related brain regions, may play an important role.Non-pharmacological therapies such as transcranial direct current stimulation, transcranial repetitive magnetic stimulation and cognitive behavior therapy have emerged to be effective interventions of great potential for chronic pain in recent years.Hereby the research progress was reviewed on the neural modulation effect of prefrontal cortex in non-pharmacological treatment of chronic pain, focusing on the related changes in brain structure and function, to further explore the underlying mechanism of pain modulation, and provide theoretical basis to optimize non-pharmacological treatment of chronic pain.

Objective:To study the relationship between somatization symptoms and body mass index (BMI), sleep and cognitive function in patients with depression.Methods:A total of 119 patients with depression were selected from January to December in 2019.According to the score of patient health questionnaire-15(PHQ15), they were divided into mild somatization group ( n=75) and moderate severe somatization group ( n=44). Hamilton depression scale-24(HAMD-24), patient health questionnaire-15, Pittsburgh sleep quality index(PSQI) and Montreal cognitive assessment(MoCA) were used to evaluate all subjects.SPSS 23.0 software was used for data analysis.Independent sample t-test was used to compare BMI, sleep and cognitive function scores between the two groups.Pearson correlation analysis was used to study the correlation between somatization symptoms and sleep quality and cognitive function. Results:There were significant differences in BMI((21.70±3.09)kg/m 2, (23.31±3.51)kg/m 2), PSQI((12.56±4.37), (14.37±3.72)), sleep quality(1.87±0.86), (2.21±0.80)), sleep disorder ((1.24±0.59), (1.65±0.53))and daytime dysfunction((2.45±0.81), (2.77±0.48)) between the two groups ( t=-3.783--2.133, all P<0.05), but no difference was found in cognition ( P>0.05). Correlation analysis showed that after controlling HAMD, PHQ-15 was positively correlated with PSQI, sleep quality, sleep disorder, daytime dysfunction and language score in MoCA ( r=0.205-0.298, all P<0.05). Conclusion:The severity of somatization in patients with depression is related to BMI, sleep quality, sleep disorder, daytime dysfunction and language function, suggesting that they may play an important role in the pathogenesis of depression with somatization.

With rapid global growth of the older population, it has been increasingly important for screening, early diagnosis, treatment and daily monitoring of cognitive function in the elderly population. Given the limited effects of pharmacological treatments, cognitive rehabilitation has the potential to improve meaningful outcomes for older people and thus comes into sight. Traditional cognitive assessment and rehabilitation require face-to-face interview, while patients with cognitive impairment are mostly elderly with difficulties in access to medical care, usually needed to be accompanied by caregivers and having other co-morbidities with limited mobility. This contradiction is especially prominent in the context of COVID-19 pandemic, which may even exacerbate cognitive decline of patients. Therefore, remote cognitive assessment and rehabilitation based on information and communication technologies have become new options. This paper introduces the widely used and validated means of remote assessment and its guiding use in cognitive rehabilitation, which can be implemented through the Internet, applications, video and telephone. The advantages of being fast, convenient and geographically agnostic lead to a wider use in large community and safeguard the health of patients with cognitive impairment.
