ABSTRACT
BACKGROUND: COVID-19 pandemic is a global crisis which results in millions of deaths and causes long-term neurological sequelae, such as Alzheimer's disease (AD). OBJECTIVE: We aimed to explore the interaction between COVID-19 and AD by integrating bioinformatics to find the biomarkers which lead to AD occurrence and development with COVID-19 and provide early intervention. METHODS: The differential expressed genes (DEGs) were found by GSE147507 and GSE132903, respectively. The common genes between COVID-19 and AD were identified. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interactions (PPI) network analysis were carried out. Hub genes were found by cytoscape. A multivariate logistic regression model was constructed. NetworkAnalyst was used for the analysis of TF-gene interactions, TF-miRNA coregulatory network, and Protein-chemical Interactions. RESULTS: Forty common DEGs for AD and COVID-19 were found. GO and KEGG analysis indicated that the DEGs were enriched in the calcium signal pathway and other pathways. A PPI network was constructed, and 5 hub genes were identified (ITPR1, ITPR3, ITPKB, RAPGEF3, MFGE8). Four hub genes (ITPR1, ITPR3, ITPKB, RAPGEF3) which were considered as important factors in the development of AD that were affected by COVID-19 were shown by nomogram. Utilizing NetworkAnalyst, the interaction network of 4 hub genes and TF, miRNA, common AD risk genes, and known compounds is displayed, respectively. CONCLUSION: COVID-19 patients are at high risk of developing AD. Vaccination is required. Four hub genes can be considered as biomarkers for prediction and treatment of AD development caused by COVID-19. Compounds with neuroprotective effects can be used as adjuvant therapy for COVID-19 patients.

Parasitic plants can adversely influence the growth of their hosts by removing resources and by affecting photosynthesis. Such negative effects depend on resource availability. However, at varied resource levels, to what extent the negative effects on growth are attributed to the effects on photosynthesis has not been well elucidated. Here, we examined the influence of nitrogen supply on the growth and photosynthesis responses of the host plant Mikania micrantha to infection by the holoparasite Cuscuta campestris by focusing on the interaction of nitrogen and infection. Mikania micrantha plants fertilized at 0.2, 1 and 5 mM nitrate were grown with and without C. campestris infection. We observed that the infection significantly reduced M. micrantha growth at each nitrate fertilization and more severely at low than at high nitrate. Such alleviation at high nitrate was largely attributed to a stronger influence of infection on root biomass at low than at high nitrate fertilization. However, although C. campestris altered allometry and inhibited host photosynthesis, the magnitude of the effects was independent of nitrate fertilizations. The infection reduced light saturation point, net photosynthesis at saturating irradiances, apparent quantum yield, CO2 saturated rate of photosynthesis, carboxylation efficiency, the maximum carboxylation rate of Rubisco, and maximum light-saturated rate of electron transport, and increased light compensation point in host leaves similarly across nitrate levels, corresponding to a similar magnitude of negative effects of the parasite on host leaf soluble protein and Rubisco concentrations, photosynthetic nitrogen use efficiency and stomatal conductance across nitrate concentrations. Thus, the more severe inhibition in host growth at low than at high nitrate supplies cannot be attributed to a greater parasite-induced reduction in host photosynthesis, but the result of a higher proportion of host resources transferred to the parasite at low than at high nitrate levels.

BACKGROUND: More than 70% of patients with depression who see their doctors experience insomnia. Insomnia treatment is a very important link for depression treatment. Furthermore, antidepression treatment is also important for depression insomnia. In acupuncture, LU-7 (Lie Que) and KID-6 (Zhao Hai), which are two of the eight confluence points in meridian theory, are used as main points. An embedded needle technique is used, alternately, at two groups of points to consolidate the treatment effect. These two groups of points are BL-15 (Xin Shu) with BL-23 (Shen Shu) and BL-19 (Dan Shu) with N-HN-54 (An Mian). The effectiveness of these optimized acupuncture formulas is well proven in the practice by our senior acupuncturists in Guangdong Provincial Hospital of TCM. This study has been designed to examine whether this set of optimized clinical formulas is able to increase the clinical efficacy of depression insomnia treatment. METHODS/DESIGN: In this randomized controlled multicenter trial, all the eligible participants are diagnosed with depression insomnia. All participants are randomly assigned to one of two groups in a ratio of 1:1 and receive either conventional acupuncture treatment or optimized acupuncture treatment. Patients are evaluated using the Pittsburgh Sleep Quality Index(PSQI)and the Hamilton rating scale(HAMD) for depression. The use of antidepression and hypnotics drugs is also considered. Results are obtained at the start of treatment, 1 and 2 months after treatment has begun, and at the end of treatment. The entire duration of the study will be approximately 36 months. DISCUSSION: A high quality of trial methodologies is utilized in the study, and the results may provide better evidence for the effectiveness of acupuncture as a treatment for depression insomnia. The optimized acupuncture formula has potential benefits in increasing the efficacy of treating depression insomnia. TRIAL REGISTRATION: The trial was registered in Chinese Clinical Trial Register (ChiCR-TRC-00000481) on 12 August 2009.

OBJECTIVE: To evaluate the clinical efficacy of acupuncture and moxibustion on chronic neck pain of cervical spondylosis in terms of the heart and kidney theory. METHODS: One hundred and eleven cases were randomized into a heart-kidney acupuncture group (55 cases) and a conventional acupuncture group (56 cases). In the heart-kidney acupuncture group, acupuncture was applied to Bailao (EX-HN 15), Shenmen (HT 7) and Wangu (SI 4). Afterwards, the direct moxibustion was applied to Dazhui (GV 14), Xinshu (BL 15) and Shenshu (BL 23). After moxibustion, the intradermal needling therapy was provided at Bailao (EX-HN 15), Xinshu (BL 15) and Shenshu (BL 23). In the conventional acupuncture group, acupuncture was applied to Bailao (EX-HN 15) and Zhongzhu (TE 3) at first. Afterwards, the direct moxibustion was done at Dazhui (GV 14), Bailao (EX-HN 15) and Jianzhongshu (SI 15). After moxibustion, the interdermal needling therapy was provided at Bailao (EX-HN 15) and Jianzhongshu (SI 15). The northwick park pain questionnaire (NPQ) was adopted as the main efficacy index for the evaluation. RESULTS: After the intervention and during the follow-up visit period, NPQ scores were all reduced remarkably as compared with those before the intervention for the patients in two groups (all P < 0.001), but the differences were not statistically significant in groups (all P > 0.05). By the age stratification analysis for the patients in two groups, the program in terms of the heart and kidney theory achieved the superior efficacy for the patients over 45 years old as compared with those in the conventional acupuncture group (P < 0.05, P < 0.01). By the stratification analysis of the sick duration, the program in terms of the heart and kidney theory achieved the superior efficacy for the patients with over 7 years sick duration as compared with those in the conventional acupuncture group (P < 0.05, P < 0.01). CONCLUSION: The acupuncture and moxibustion therapeutic program in terms of the heart and kidney theory achieves the superior efficacy on chronic pain of cervical spondylosis for the patients over 45 years old and with over 7 years sick duration. It is one of the optimized programs for the treatment of this disease.

BACKGROUND: Neck pain is one of the chief symptoms of cervical spondylosis (CS). Acupuncture is a well-accepted and widely used complementary therapy for the management of neck pain caused by CS. In this paper, we present a randomized controlled trial protocol evaluating the use of acupuncture for CS neck pain, comparing the effects of the optimized acupuncture therapy in real practice compared with sham and shallow acupuncture. METHODS/DESIGN: This trial uses a multicentre, parallel-group, randomized, sham acupuncture and shallow acupuncture, controlled single-blind design. Nine hospitals are involved as trial centres. 945 patients who meet inclusion criteria are randomly assigned to receive optimized acupuncture therapy, sham acupuncture or shallow acupuncture by a computerized central randomization system. The interventions past for 4 weeks with eight to ten treatments in total. The group allocations and interventions are concealed to patients and statisticians. The Northwick Park Neck Pain Questionnaire (NPQ) is used as the primary outcome measure, and the McGill Pain Questionnaire (MPQ) and The Short Form (36) Health Survey (SF-36) are applied as secondary outcome measures. The evaluation is performed at baseline, at the end of the intervention, and at the end of the first month and the third month during follow-up. The statistical analyses will include baseline data comparison and repeated measures of analysis of variance (ANOVA) for primary and secondary outcomes of group and time differences. Adverse events (AEs) will be reported if they occur. DISCUSSION: This trial is a multicentre randomized control trial (RCT) on the efficacy of acupuncture for CS neck pain and has a large sample size and central randomization in China. It will strictly follow the CONSORT statement and STRICTA extension guideline to report high-quality study results. By setting the control groups as sham and shallow acupuncture, this study attempts to reveal the effects of real acupuncture versus placebo or non-classic acupuncture treatment and evaluate whether classic Chinese medical acupuncture is effective on CS neck pain. This study will provide evidence for the effects of acupuncture on CS neck pain. TRIAL REGISTRATION: Chinese Clinical Trial Registry: ChiCTR-TRC-00000184.

The skull of the master of M392 tomb 5000 years ago unearthed in Guangrao County, Shandong province from 1995 to 1996 had a round and smooth-edged bone defect at its left parietal part. By using the methods of morphological observation and medical imaging, a contrastive research was made between the characteristics of unearthed skull specimens and that of the healing edge of fenestrate bone of the skull after craniotomy and that caused by all sorts of diseases. It is thus proved that the skull defect of M392 tomb master was caused by craniotomy.
