RESUMO
In recent years， the incidence of colorectal cancer has been rising in China， and with the promotion of early screening and early diagnosis， most colorectal cancers are able to achieve long-term survival through timely diagnosis and treatment. Nevertheless， 30%-70% of patients with early to mid-stage colorectal cancer after radical surgery still have psychological problems such as anxiety， depression， and fear of recurrence and metastasis， and they hope to seek help from traditional Chinese medicine（TCM） treatment. In order to further standardize the integrated traditional Chinese and western medicine psychological rehabilitation interventions of stage Ⅰ-Ⅲ colorectal cancer after radical surgery， and to improve the diagnosis and treatment level， under the support of the pilot project of clinical collaboration between Chinese and western medicine for major and difficult diseases of National Administration of TCM， experts in oncology， integrated Chinese and western medicine， psychology， surgery， nursing， evidence-based medicine and other disciplines from 10 units nationwide participated in the work， led by Xiyuan Hospital，China Academy of Chinese Medical Sciences and Beijing Cancer Hospital. Based on the methodology and process of guideline development of the World Health Organization Handbook for Guideline Development and the Regulations for Group Standards of China Association of Chinese Medicine， the Guidelines for Psychological Rehabilitation Intervention Combined Integrated Traditional Chinese and Western Medicine After Radical Surgery for Early and Middle Stage Colorectal Cancer have been developed according to the current best evidence， extensive consultation with clinical experts and following the situation of current clinical practice. The guideline provides the psychological characteristics， the needs and willingness to accept psychological rehabilitation， the interventions for psychological rehabilitation， evaluation of efficacy， follow-up review， educational guidance and others of patients with stage Ⅰ-Ⅲ colorectal cancer after radical surgery. It can provide guidance for TCM（integrated Chinese and western medicine） clinicians and psychologists engaged in the psychological rehabilitation of integrated Chinese and western medicine oncology， especially for doctors in primary medical institutions.
RESUMO
Objective:To observe the effects of Jieyu Zhitong Prescription on the behavior of migraine-depressed comorbid model rats; To explore its mechanism from the perspective of regulating brain derived neurotrophic factor (BDNF)/ERK1/2/cyclic adenosine responsive element binding protein (CREB) signaling pathway.Methods:Totally 36 SD male rats were divided into blank group, model group, nimodipine group and low-, medium-and high-dose group of Chinese medicine according to random number table method. The migraine-depressive comorbidity model was replicated by intermittent subcutaneous injection of nitroglycerin (10 mg/kg) and chronic unpredictable mild stimulation. Rats in each group were given corresponding drug intervention for 21 days, once a day. The weight of rats in each group before and on the 10th and 21st days after modeling was recorded. The threshold of mechanical pain was detected, and the behavior of rats was evaluated by open field test, forced swimming test, and novelty inhibition feeding test. The protein expressions of BDNF, TrKB, p-ERK1/2 and p-CREB in rat hippocampus were detected by Western blot.Results:On the 10th and 21st day of modeling intervention, compared with model group, the body weight, the scores of horizontal and vertical activity in open field experiment in each dose group of Chinese medicine increased ( P<0.05), and the latent time of novelty inhibition feeding and immobile time of forced swimming were shortened ( P<0.05). On the 7th, 14th and 21st days, compared with the model group at the same time point, the threshold of mechanical pain of rats in each dose group of Chinese medicine increased ( P<0.05). The expression of p-ERK1/2 protein increased in hippocampal tissue in each dose group of Chinese medicine ( P<0.05), and the expression of BDNF, TrkB, and p-CERB protein increased in the low- and high-dose group of Chinese medicine ( P<0.05). Conclusion:Jieyu Zhitong Prescription can significantly improve the symptoms of migraine-depressed comorbid rats, and its mechanism may be analgesic and antidepressant by affecting the expression of proteins in the BDNF/ERK1/2/CREB signaling pathway.
RESUMO
From birth to adulthood, we often align our behaviors, attitudes, and opinions with a majority, a phenomenon known as social conformity. A seminal framework has proposed that conformity behaviors are mainly driven by three fundamental motives: a desire to gain more information to be accurate, to obtain social approval from others, and to maintain a favorable self-concept. Despite extensive interest in neuroimaging investigation of social conformity, the relationship between brain systems and these fundamental motivations has yet to be established. Here, we reviewed brain imaging findings of social conformity with a componential framework, aiming to reveal the neuropsychological substrates underlying different conformity motivations. First, information-seeking engages the evaluation of social information, information integration, and modification of task-related activity, corresponding to brain networks implicated in reward, cognitive control, and tasks at hand. Second, social acceptance involves the anticipation of social acceptance or rejection and mental state attribution, mediated by networks of reward, punishment, and mentalizing. Third, self-enhancement entails the excessive representation of positive self-related information and suppression of negative self-related information, ingroup favoritism and/or outgroup derogation, and elaborated mentalizing processes to the ingroup, supported by brain systems of reward, punishment, and mentalizing. Therefore, recent brain imaging studies have provided important insights into the fundamental motivations of social conformity in terms of component processes and brain mechanisms.

Objective To investigate the effects of calorie restriction (CR) for 4 weeks on twitch tension,titanic tension,and fatigue contraction induced by electrical stimulation in different kind skeletal muscles from rats and explore the possible mechanisms.Methods The rat model of CR was established by a limitation of 40％ calorie intake of control rats for 4 weeks,and then oral glucose tolerance test (OGTT) was performed.The soleus (SOL) and extensor digitorum longus (EDL) were isolated under anesthetization to detect twitch tension,titanic tension,and fatigue contraction induced by electrical stimulation.Adenosine triphosphate (ATP) content was measured by fluorescent enzymatic methods to reflect mitochondrial function.The ratio of mitochondrial gene COX Ⅰ and nuclear gene β-actin copy number was analyzed to evaluate mitochondrial biogenesis.Furthermore,the transcriptions of peroxisome proliferatoractivated receptor γ coactivator-1 (PGC-1α) and nuclear respiratory factor 1 (NRF1) genes,expressions of phosphorylated adenosine 5'-monophosphate-activated protein kinase (AMPK) and nitric oxide synthase (NOS) proteins,and nitric oxide (NO) content were determined in skeletal muscle.Results The blood glucose level at 30 min and area under the curve of blood glucose levels at various time points during OGTT were significantly decreased in the CR group compared to the control group.The twitch tension [(2.5 ± 0.15)N/cm2 vs (1.24±0.12)N/cm2,(2.66 ±0.21)N/cm2 vs (1.69 ±0.17)N/cm2,P ＜ 0.05],titanic tension [(10.43 ± 0.36) N/cm2 vs (8.06 ± 0.19) N/cm2,(11.35 ± 1.02) N/cm2 vs (8.12 ± 0.23) N/cm2,P ＜ 0.05],and fatigue contraction force in SOL and EDL from CR rats were significantly increased in association with increases of ATP content [(34.82 ±4.31)) mnol/mg protein vs (15.32 ± 1.94) nmol/mg protein,(30.82 ± 2.15) nmol/mg protein vs (12.32 ± 0.97) nmol/mg protein,P ＜ 0.05] and mitochondrial biogenesis (2.75 ± 0.20 vs 1.52 ± 0.06,1.32 ± 0.10 vs 0.84 ± 0.11,P ＜ 0.05) compared to control rats.CR for 4 weeks upregulated the transcriptions of PGC-1α and NRF genes as well as the phosphorylation of AMPK protein in SOL but not in EDL.Furthermore,CR also enhanced NOS expression and NO content in both skeletal muscles.Conclusions CR for 4 weeks can strengthen the contractile function of SOL and DL from rats,and the underlying mechanisms might be related to the upregulation of PGC-1α transcription and AMPK activation,resulting in the enhances of mitochondrial biogenesis and mitochondrial function in skeletal muscles.
