OBJECTIVE@#To explore the protective effect and mechanism of Kuntai (KT) Capsule on angiotensin II (Ang II)-induced hypertension in ovariectomized (OVX) rats.@*METHODS@#Fifty-four rats were randomly divided into 6 groups according to a random number table, 9 in each group: control, OVX sham+Ang II, OVX, OVX+Ang II, OVX+Ang II +E2, and OVX+Ang II +KT. OVX rats model was constructed by retroperitoneal bilateral ovariectomy. After 4 weeks of pretreatment with KT Capsule [0.8 g/(kg·d) and 17- β -estradiol (E2, 1.2 mg/(kg·d)] respectively, Ang II was injected into a micro-osmotic pump with a syringe to establish a hypertensive rat model. Blood pressure of rat tail artery was measured in a wake state of rats using a non-invasive sphygmomanometer. Blood pressure changes were compared between the intervention groups (OVX+Ang II +KT, OVX+Ang II +E2) and the negative control group (OVX+Ang II). Serum malondialdehyde (MDA) level and superoxide dismutase (SOD) activity were detected respectively. The expressions of oxidative stress-related protein superoxide dismutase2 (SOD2) and anti-thioredoxin (TRX), autophagy marker protein [beclin1, light chain (LC) 3 II/I ratio and autophagy canonical pathway protein phosphatidylinositol 3-kinase (PI3K)/serine/threonine kinase (AKT)-mammalian target of rapamycin (mTOR)] were evaluated by Western blotting.@*RESULTS@#Compared with the OVX+Ang II group, the systolic blood pressure of OVX+Ang II +KT group was significantly lowered (P<0.05) but not the diastolic blood pressure. Besides, SOD2 and TRX protein levels in mycardial tissues were significantly reduced in the OVX+Ang II +KT group compared with the OVX+Ang II group (P<0.05). Oxidative stress serum markers MDA and SOD were down- and up-regulated in the OVX+Ang II +KT group, respectively (P<0.05). Compared with OVX+Ang II group, the levels of cardiac proteins beclin-1 and LC3II/LC3 I in OVX+Ang II +KT group were also up-regulated (P<0.05), and the expression levels of p-PI3K, p-AKT and mTOR protein were down-regulated (P<0.05).@*CONCLUSION@#KT could protect blood pressure of Ang II-induced OVX rats by inhibiting oxidative stress and up-regulating protective autophagy.

Predictors of rapid eye movement sleep behavior disorder in patients with Parkinson's disease based on random forest and decision tree.

BACKGROUND AND OBJECTIVES: Sleep disorders related to Parkinson's disease (PD) have recently attracted increasing attention, but there are few clinical reports on the correlation of Parkinson's disease patients with rapid eye movement (REM) sleep behavior disorder (RBD). Therefore, this study conducted a cognitive function examination for Parkinson's disease patients and discussed the application effect of three algorithms in the screening of influencing factors and risk prediction effects. METHODS: Three algorithms (logistic regression, machine learning-based regression trees and random forest) were used to establish a prediction model for PD-RBD patients, and the application effects of the three algorithms in the screening of influencing factors and the risk prediction of PD-RBD were discussed. RESULTS: The subjects included 169 patients with Parkinson's disease (Parkinson's disease with RBD [PD-RBD] = 69 subjects; Parkinson's disease without RBD [PD-nRBD] = 100 subjects). This study compared the predictive performance of RF, decision tree and logistic regression, selected a final model with the best model performance and proposed the importance of variables in the final model. After the analysis, the accuracy of RF (83.05%) was better than that of the other models (decision tree = 75.10%, logistic regression = 71.62%). PQSI, Scopa-AUT score, MoCA score, MMSE score, AGE, LEDD, PD-course, UPDRS total score, ESS score, NMSQ, disease type, RLSRS, HAMD, UPDRS III and PDOnsetage are the main variables for predicting RBD, along with increased weight. Among them, PQSI is the most important factor. The prediction model of Parkinson's disease RBD that was established in this study will help in screening out predictive factors and in providing a reference for the prognosis and preventive treatment of PD-RBD patients. CONCLUSIONS: The random forest model had good performance in the prediction and evaluation of PD-RBD influencing factors and was superior to decision tree and traditional logistic regression models in many aspects, which can provide a reference for the prognosis and preventive treatment of PD-RBD patients.

Mediating effects of self-esteem on the relationship between mindful parenting and social anxiety level in Chinese adolescents.

This study aimed to investigate the relationship between mindful parenting and social anxiety level in Chinese adolescents and to explore the mediating roles of self-esteem between mindful parenting and social anxiety level. A total of 302 adolescents and their main caregivers were investigated by using the Chinese version of the Mindful Parenting Scale, Self-Esteem Scale and the Center for Epidemiological Studies Depression Scale and the Social Anxiety Scale. Related analysis was used to investigate the relationship between mindful parenting, self-esteem and social anxiety level. Mindful parenting and self-esteem were significantly associated with social anxiety level. Self-esteem mediated the relationship between mindful parenting and social anxiety level. Both mindful discipline and being in the moment influenced adolescents' social anxiety level through self-esteem. Self-esteem completely mediated the association between mindful parenting and social anxiety level. Longitudinal research is needed to better understand the relationship between mindful parenting and social anxiety level in adolescents.

Herbal Textual Research on Coptidis Rhizoma in Famous Classical Formulas / 中国实验方剂学杂志

Through the combing of ancient books of Chinese herbal medicine in the past dynasties， a textual research of Coptidis Rhizoma involved the name， origin， medicinal parts， producing area， quality evaluation， harvesting and processing methods in famous classical formulas was conducted in this paper. After textual research， the mainstream varieties of Coptidis Rhizoma in the Ranunculaceae family before Tang and Song dynasties were Coptis chinensis and C. chinensis var. brevisepala， after the Ming and Qing dynasties， C. deltoidea， C. teeta and C. omeiensis were gradually praised. In ancient times， the authentic producing area of Coptidis Rhizoma has the characteristics of gradually moving to the west. The eastern Coptidis Rhizoma was highly praised in the early stage， while in the later stage， western Coptidis Rhizoma like chicken feet was highly praised. In the early stage， western Coptidis Rhizoma probably originated from C. chinensis and its genus， while Coptidis Rhizoma like chicken feet was cultivated， and no wild species has been found so far. As Coptidis Rhizoma has mixed use of multiple origins in ancient books of past dynasties， based on the current shortage of market resources in C. teeta and C. deltoidea， there are also endangered and protected plants of C. chinensis var. brevisepala and C. omeiensis， combined with the mainstream medicines and resources of past generations， it is recommended to choose C. chinensis as the base of the formulas. In ancient times， there were many processing methods for Coptidis Rhizoma， such as frying and wine-， ginger-， honey-processed. In the process of developing famous classical formulas， the appropriate processing specifications of Coptidis Rhizoma should be selected based on the original source records and the requirements of the medicinal material.

ObjectiveTo analyze the endemic situation of schistosomiasis in national surveillance sites of Zhenjiang City from 2015 to 2019, so as to provide the scientific basis for the consolidation of schistosomiasis control achievements and timely treatment of risk factors. MethodsA total of 7 national schistosomiasis surveillance sites were assigned in Zhenjiang City from 2015 to 2019. According to the National Scheme for Schistosomiasis Surveillance (2014 version), Schistosoma japonicum infections were monitored in local residents, floating populations and livestock, and snail habitats were surveyed in Zhenjiang City from 2015 to 2019. The results of schistosomaisis surveillance in Zhenjiang City from 2015 to 2019 were analyzed. Results There were 15 848 and 7 779 person-times of local residents and floating populations receiving serological screening of schistosomiasis in 7 national surveillance sites of Zhenjiang City from 2015 to 2019, and the seroprevalence rates were 0.95% to 1.75% and 0.14% to 0.91% among local residents and floating populations, respectively; however, no egg-positives were identified. A total of 1 885 herd-times of livestock were detected, and no egg-positives were found. During the 5-year period, snail survey was conducted in snail habitats and suspected snail habitats covering 3 333.79 hm2, and there were 108.71 hm2 snail habitats identified, including 50.97 hm2 re-emerging snail habitats. The density of living snails was 0.007 to 0.125 snails/0.1 m2 from 2015 to 2019, which showed a trend for a rise year by year (χ2 = 2 732.626, P < 0.01); however, no S. japonicum infections were detected in snails. Conclusions The endemic situation of schistosomiasis has been maintained at a low level in Zhenjiang City, and schistosomiasis control achievements are consolidated. However, snails are widely distributed in the city, and there are still risk factors associated with schistosomiasis transmission.

Study on immunological functions of heat shock protein 40 kDa of Schistosoma japonicum / 中国血吸虫病防治杂志

Objective To investigate the immunological functions of heat shock protein 40 kDa of Schistosoma japonicum (SjHSP40). Methods The homology of the SjHSP40 protein sequence was analyzed and the B and T cell epitopes of SjHSP40 were predicted using bioinformatics tools. The full-length SjHSP40 gene was amplified using a PCR assay, and cloned into the prokaryotic expression vector pGEX-6P-1, which was transformed into Escherichia coli BL-21. The protein expression was induced with isopropyl β-D-thiogalactoside (IPDG), and then, the recombinant protein was purified with glutathione-sepharose 4B resin to yield the fusion protein GST-SjHSP40, which was checked with SDS-PAGE and Western blotting. Following immunization with GST-SjHSP40, the serum levels of anti-SjHSP40 IgG antibody and IgG1 and IgG2a subtypes were detected in BALB/c mice using ELISA. In addition, the effect of SjHSP40 on CD4+ T-cell subset differentiation was examined using flow cytometry. Results SjHSP40 contained 7 potential B cell epitopes and multiple T cell epitopes (CTL epitopes and Th epitopes). The prokaryotic expression plasmid pGEX-6p-1-SjSHP40 was successfully constructed, and the fusion protein GST-SjHSP40 was obtained following IPDG induction and protein purification. Significantly higher serum levels of anti-SjHSP40 IgG, IgG1 and IgG2a antibodies were detected in mice immunized with GST-SjHSP40 than in other groups; however, SjHSP40 showed no remarkable effects on CD4+ T-cell subset differentiation. Conclusions SjHSP40 may induce specific humoral immune responses in mice; however, it does not affect the balance of Th immune responses. It is suggested that SjHSP40 may be a potential vaccine candidate.

Objective To observe the relationship between serum Klotho levels and the progression of renal function in patients with chronic kidney disease (CKD)and investigate further the feasibility of serum Klotho levels for predicting the progression of renal function in CKD patients.Methods Eighty-one non-dialysis patients with CKD 3 to 5 stages and 30 healthy volunteers in the First People's Hospital of Kunshan were enrolled for a 12 months of follow-up.The levels of Klotho and fibroblast growth factor 23 (FGF23) in serum were detected by ELISA at the beginning and the end of the follow-up.The other related indicators were also tested simultaneously.GFR values were calculated by MDRD and GC formulas.According to the decreasing range of GFR,the CKD patients were subdivided into two groups:deterioration group and stability group for renal function,and the relationships between Klotho levels and progression of kidney function were evaluated.Results The patients were followed up for an average of (9.5 + 2.9) months.GFR in CKD patients decreased from (24.8 ± 12.4) mL/min to (18.7 ± 12.1) mL/min (P ＜ 0.0 1),and serum Klotho level decreased from 2.53 (1.41,3.67)ng/mL to 1.63 (1.07,3.19)ng/mL (P ＜0.01)with more pronounced trend in the patients with renal function deterioration than the patients in stability group (P ＜0.01).Fifteen patients with high Klotho level suffered from adverse kidney outcomes while 26 ones with lower Klotho level suffered from deterioration of renal function (63.4％ vs 36.5％,P =0.02).KaplanMeier analysis revealed the high risk of adverse kidney outcomes arose in the CKD patients with lower Klotho level (P =0.013).Conclusion Klotho level in CKD patients may significantly decrease and should be more apparent with renal function progresses.Lower Klotho level in serum may be associated with high risk of adverse kidney outcomes and become a promising marker to predict CKD progression.

Progress in multisensory integration during self motion processing / 生理学报

In the daily life, we perceive the world around us by integrating multiple sensory cues (visual, auditory, olfactory, gustatory, tactile, vestibular and proprioceptive) to create a coherent, reliable representation that allows us to interact meaningfully with the environment. The integration of different sensory information is necessary for our perception, motor transformation, decision making, learning and memory. In the past decades, many interdisciplinary researchers have been attracted to the field of multisensory research, and tremendous advances have been made in this field. We review the researches on multisensory integration during self-motion perception in the past decades from the candidate areas, the integration principles and the neural correlation of the behaviors, with the intention to provide a comprehensive source for those interested in understanding the neural substrates for multisensory integration. Meanwhile, we also provide a prospect for the future research in this field.

[Effect of health education of schistosomiasis control with Yi-Han bilingualism].

OBJECTIVE: To evaluate the intervention effect of Yi-Han bilingual health education of schistosomiasis control. METHODS: Baimiao Village in Daqing Town, Xichang City, where Yi Nationality inhabited, was chosen as a pilot to carry out Yi-Han bilingual health education of schistosomiasis control from 2012 to 2015. The villagers and students in the pilot area were investigated by questionnaires before and after the intervention to understand their awareness and correct behavior status on schistosomiasis control. RESULTS: After the intervention of Yi-Han bilingual health education of schistosomiasis control for 3 years, the awareness rate and the correct rate of behavior on schistosomiasis control of the villagers in the pilot area improved from 45.79% and 51.12% in 2012 to 97.80% and 98.78% in 2015. As for the students, the two rates mentioned above improved from 64.16% and 60.83% in 2012 to 100% and 98.89% in 2015 respectively, and all the differences between the rates before and after the intervention were statistically significant (all P < 0.01). CONCLUSIONS: The intervention of Yi-Han bilingual health education of schistosomiasis control can obviously improve the knowledge awareness rates and the correct rates of behavior of the residents and students in the gathering area of Yi Nationality.
