Perilla frutescens, an annual herb of the Labiatae family, has been cultivated in China for more than 2000 years. P. frutescens is the one of the first medicinal and edible plant published by the Ministry of Health. Its leaves, stems and seeds can be used as medicine and edible food. Because of the abundant nutrients and bioactive components in this plant, P. frutescens has been studied extensively in medicine, food, health care and chemical fields with great prospects for development. This paper reviews the cultivation history, chemical compositions and pharmacological activities of P. frutescens, which provides a reference for the development and utilization of P. frutescens resources.

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.

Previous studies suggest that the reduction of SMAD3 (mothers against decapentaplegic homolog 3) has a great impact on tumor development, but its exact pathological function remains unclear. In this study, we found that the protein level of SMAD3 was greatly reduced in human-grade IV glioblastoma tissues, in which LAMP2A (lysosome-associated membrane protein type 2A) was significantly up-regulated. LAMP2A is a key rate-limiting protein of chaperone-mediated autophagy (CMA), a lysosome pathway of protein degradation that is activated in glioma. We carefully analyzed the amino-acid sequence of SMAD3 and found that it contained a pentapeptide motif biochemically related to KFERQ, which has been proposed to be a targeting sequence for CMA. In vitro, we confirmed that SMAD3 was degraded in either serum-free or KFERQ motif deleted condition, which was regulated by LAMP2A and interacted with HSC70 (heat shock cognate 71 kDa protein). Using isolated lysosomes, amino-acid residues 75 and 128 of SMAD3 were found to be of importance for this process, which affected the CMA pathway in which SMAD3 was involved. Similarly, down-regulating SMAD3 or up-regulating LAMP2A in cultured glioma cells enhanced their proliferation and invasion. Taken together, these results suggest that excessive activation of CMA regulates glioma cell growth by promoting the degradation of SMAD3. Therefore, targeting the SMAD3-LAMP2A-mediated CMA-lysosome pathway may be a promising approach in anti-cancer therapy.

Objective:To systematically evaluate the experience of self-management in peritoneal dialysis patients.Methods:Databases including PubMed, Embase, Web of Science, the Cochrane Library, PsycInfo, Scopus and CNKI, Wanfang, VIP, CBM and Google Scholar were searched and relevant qualitative research on self-management experience of peritoneal dialysis patients was retrieved with a time limitation from the establishment of the databases to April 6, 2020. The quality of articles was evaluated by the quality evaluation standard of qualitative research of JBI evidence-based health care center (2008) , and the results were Meta integrated.Results:A total of 8 studies were included, and 26 complete research results were extracted. We summed up 10 new categories, and obtained 3 integrated results. Integration result 1: cognitive and behavioral management. Patients try to maintain the independence and confidence of peritoneal dialysis management through facing renal failure and adapting to dialysis treatment. Integration result 2: crisis identification and management of complications. Through continuous learning of knowledge and skills related to dialysis treatment, as well as identification and treatment of worsening symptoms, patients can improve their ability of crisis identification and management. Integration result 3: role and social relationship management. Patients constantly adjust their roles and emotions to adapt to changes in daily life and maintain social functions and strive to strengthen communication with medical care, family and society to obtain social relationship support, and increase patients' confidence in self-management.Conclusions:The self-management of peritoneal dialysis patients involves many aspects. The medical staff should give understanding, guidance, and support to the patients' self-management and self-care process in combination with family and society, to help them with better self-management and improve their quality of life.

Objective:To investigate different sleep duration and glucose and lipid metabolism levels in residents of a community in Urumqi.Methods:Using the 2 049 residents′ data of chronic metabolic disease in a community of Urumqi collected in May 2017, 1 822 subjects aged between 19-80 years with complete information were enrolled, their blood pressure, waist circumference, height, weight, body mass index were measured and recorded. Using oral glucose tolerance test to measure fasting and 2 h after meal plasma glucose, uric acid, HbA 1C, total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C) levels were all tested. Results:(1)There were 363 (19.9%), 1 349 (74.0%), and 110 (6.1%) respondents with sleep time≤6.0, 6.1 to 8.0, and>8.0 h/d, respectively. There were statistically significant differences in age, education, and family income in groups with different sleep time ( P<0.05), while their gender, smoking status, and exercise status were not statistically significant ( P>0.05). The rates of overweight, obesity, abdominal obesity, high uric acid, and hypertension in people with different sleep durations were statistically different ( P<0.01). The rates of the above indicators were higher in the group of sleep time≤6.0 h/d than the other two groups. (2) Differences in diastolic blood pressure, systolic blood pressure, body mass index, abdominal circumference, total cholesterol, and LDL-C levels were statistically significant among different sleep duration groups ( P<0.05). Further comparisons of the above indicators among three groups with different sleep durations were performed ( P<0.05). The levels of the above indicators in the sleep time≤6.0 h/d group were higher than those in the other two groups. There were no significant differences in fasting blood glucose, glycated hemoglobin, uric acid, triglyceride, and HDL-C among the three groups. (3) Multivariate logistic regression analysis showed that groups whether or not adjusted of age, family income, and education level, sleep time≤6.0 h/d was related to abdominal obesity, and sleep time≤6.0 h/d was be a risk factor for abdominal obesity [Unadjusted: OR=1.48(95% CI1.04-2.08); Adjusted: OR=1.65(95% CI1.18-2.32; P<0.05]. Conclusion:Sleep time ≤6.0 h/d is associated with abdominal obesity, and sleep time≤6.0 h/d may be a risk factor for abdominal obesity.

Objective:To observe the dynamic changes of thyroid hormone levels and thyroid autoimmune antibodies in pregnant women in Xinjiang Uygur Autonomous Region during pregnancy, and to investigate the significance of repeated screening of thyroid function in different gestational ages.Methods:A retrospective study was carried out of pregnant women who completed thyroid function screening in Clinic, People's Hospital of Xinjiang Uygur Autonomous Region from January 2015 to December 2017, and the test results of thyroid stimulating hormone (TSH), free thyroxine (FT 4), free triiodothyronine (FT 3), thyroid peroxidase antibody (TPOAb), and anti-thyroglobulin antibody (TGAb) were collected and analyzed of their changes during pregnancy. Pregnant women were divided into 2 different gestational age groups by the age limit of 30, the changes of thyroid dysfunction rate with pregnancy were analyzed, and the clinical significance of repeated screening in different pregnancy stages was discussed. Results:Changes of thyroid-related indicators with pregnancy: first, second, and third trimesters were 404,725, and 767 cases, respectively; TSH level in the third trimester (2.76 mU/L) was significantly higher than those in the first and second trimesters (2.55, 2.36 mU/L, P < 0.05), there was no significant difference between the first trimester and the second trimester ( P > 0.05); the FT 4 and FT 3 levels decreased gradually with pregnancy ( P < 0.05); the positive rate of TPOAb was significantly higher in the first and second trimesters than that in the third trimester ( P < 0.05), there was no significant difference between the first trimester and the second trimester ( P > 0.05); the positive rate of TGAb decreased gradually with pregnancy ( P < 0.05). Comparison of abnormal rate of TSH in different gestational ages: the first, second, and third trimesters were 352, 664, 735 cases, respectively; the abnormal rate of TSH in the overall study was statistically significant at different stages of pregnancy (χ 2=31.627, P < 0.05), the first trimester was significantly higher those in the second and third trimesters ( P < 0.05). In pregnant women aged ≥30 years old, the abnormal rate of TSH in the first trimester was significantly higher than those in the second and third trimesters ( P < 0.05); in pregnant women aged < 30 years old, the abnormal rate of TSH in the first trimester was significantly higher than that in the third trimester ( P < 0.05). There were no significant differences in the abnormal rate of TSH in the first, second, and third trimesters between the < 30 years old group and ≥30 years old group ( P > 0.05). Comparison of abnormal rate of FT 4 in different gestational ages: there were no significant differences in the FT 4 abnormal rate among different pregnancy groups in the overall, < 30, ≥30 years old groups (P > 0.05). In early pregnancy, the abnormal rate of FT 4 in the ≥30 years old group was higher than that in the < 30 years old group ( P < 0.05); in second and third trimesters, there were no significant differences between the two age groups ( P > 0.05). Conclusions:Screening for thyroid function in the first trimester of pregnancy is important for women of different ages. Except for women with abnormal thyroid function who have not been treated during the first trimester, the rest may not need to be screened again. Pregnant women aged ≥30 years old may have a higher risk of thyroid dysfunction than those < 30 years old.

Objective To establish a reference range for specific thyroid function during pregnancy and to explore the influencing factors of hypothyroxinemia during pregnancy.Methods A retrospective analysis of 2 996 cases of thyroid function in the pregnant women who were with single pregnancy and without thyroid diseases and family history of those diseases.Results (1) Establish a unified reference range for specific thyroid function during pregnancy;the early,middle,and late trimesters thyrotropin (TSH) ranges were 0.02-6.39,0.16-6.23,0.64-6.59 mU/L,respectively,while free thyroxine (FT4) ranges were 11.32-23.00,9.39-18.92,8.54-16.73 pmol/L respectively.The specific reference ranges of Han and Uygur pregnant women were established separately.There was no difference in the detection rates of various thyroid diseases when using their respective reference ranges and the unified reference range of the hospital (P ＞ 0.05).(2) The detection rate of various thyroid diseases (except subclinical hyperthyroidism) of our subjects with China guideline reference range was significantly higher than the reference range with the hospital (P＜0.05).(3) The detection rates of hypothyroxinemia in all pregnant women with FT4 cut points of P2.5 and P5 were 4.3％ and 7.4％,respectively,of which the Han population was 4.3％ and 7.1％,respectively,and the Uygur population was 4.3％ and 7.9％,respectively.(4) Comparing the mean age,gestational age,median urine iodine,and thyroid antibody positive rate between the hypothyroxinemia group and the control group,only the mean age and gestational age were different (P＜0.05);Logistic binary regression analysis showed that age was the risk factor for hypothyroxinemia during pregnancy (OR =1.035,95％ CI 1.006-1.066,P ＜ 0.05).Conclusions The Han and Uygur pregnant women in this area both can use the thyroid reference range of our hospital during pregnancy.The establishment of thyroid reference range may avoid over-diagnosis of thyroid disease during pregnancy.Age is a possible influencing factor of hypothyroxinemia during pregnancy.

Objective: To study the effects of a standardized diagnosis and treatment program for type 2 diabetes mellitus patients, in a community in Urumqi. Methods: In March 2016, 1 000 patients with type 2 diabetes at the Urumqi Xinhua Road community health service center and affiliated communities were selected to participate in a questionnaire survey and in a promotion for a 12-month standardized treatment. T-test and χ² test were used to compare the blood sugar, blood pressure, blood lipids, ratio of urine microalbumin and creatinine (urine A/C) and other metabolic indices in patients before and after the promotion. Results: In a total of 112 finalists, after a 4-month follow-up, rates of regular exercise, diet control, taking medication on time and regular blood glucose monitoring all improved significantly from 35.7%, 40.2%, 13.7%, 29.5% to 56.3%, 68.8%, 56.3%, 45.5%, respectively (χ²=9.508, 8.643, 45.319, 6.171; P < 0.05). The rates of smoking and drinking were lower after the promotion (χ²=4.291, 4.56; P < 0.05). Body mass index (BMI), fasting blood glucose (FPG), glycated hemoglobin (HbA1c), systolic blood pressure, total cholesterol (TC), creatinine, and urine A/C decreased significantly, while there was no significant difference in the diastolic blood pressure. The percentage of participants with normal blood sugar, lipids and blood pressure, significantly improved from 38.4%, 37.5%, 23.6%, 8.9% to 63.4%, 66.4%, 43.7%, 23.2%, respectively. The rate of urine A/C positivity decreased from 40.2% to 26.8% (χ²=14.004, 18.309, 10.604, 8.473, 4.510, P < 0.05). Conclusion Standardized type 2 diabetes treatment programs can improve the blood levels of glucose and lipids, as well as lower blood pressure and the positive rate of urine A/C. It can help reduce the multiple risk factors and long-term complications by improving the self-management of diabetes.
