To investigate the role of miRNA-335 on the proliferation and apoptosis of placental trophoblast cells in preeclamptic rats and its potential mechanism.
Placental trophoblast cells were isolated from preeclamptic model rats and normal ones. Trophoblast cells from the model group were divided into six groups for transfection the blank (empty vector) group, the NC (negative control) group, the miRNA-335 mimic group, the miRNA-335 inhibitor group, the CRIM1 (overexpressed recombinant plasmid) group, and the miRNA-335 inhibitor + CRIM1 group. The miRNA-335 expressions after the transfection were determined using qRT-PCR. The mRNA and protein expressions of CRIM1, the transforming growth factor (TGF-β1), and the apoptosis-related factors (Bax and Bcl-2) in each group were determined using qRT-PCR and Western blotting. The cell proliferation and apoptosis were determined using MTT assays and flow cytometry, respectively.
Compared with normal rats, the systolic blood pressure, diastolic blood pressure, and urinary protein levels were increased in the model rats, which had increased miRNA-335 expressions, but a decreased CRIM1 expressions (all P<0.05). The inhibition of miRNA-335 promoted the expressions of CRIM1, TGF-β1, and Bcl-2 and inhibited the expression of Bax in trophoblast cells (all P<0.05). miRNA-335 inhibition or CRIM1 over-expression promoted the proliferation and reduced the apoptosis of trophoblast cells. The combined effect of miRNA-335 inhibition or CRIM1 over-expression had an even more significant effect on the changes in the above indicators (all P<0.05).
miRNA-335 inhibition can enhance the expression of CRIM1 to promote the proliferation and reduce the apoptosis of trophoblast cells in preeclamptic rats.

To analyze the effects of mindfulness-based cognitive therapy (MBCT) plus loving-kindness mediation (LKM) in depressed patients.
A total of 125 depressed patients diagnosed in the Department of Psychiatry of our hospital were selected as the research subjects and were randomly divided into a control group (n=62) and an observation group (n=63). The control group was treated with conventional psychological intervention, while the observation group was treated with MBCT plus LKM. The therapeutic outcomes were compared between the two groups.
At 2, 4, 6 and 8 weeks after intervention, the Hamilton Depression Rating Scale (HAMD) scores and the scores for introspection and deliberation, forced thinking, rumination of symptoms, treatment, ability and social relationships in the observation group were lower than those in the control group, while Five Facet Mindfulness Questionnaire (FFMQ) scores and the scores for psychology, environment, physiology, social relations, self-acceptance, and self-evaluation in the observation group were higher than those in the control group (
< 0.05).
MBCT plus LKM can effectively improve depression, rumination, mindfulness level, quality of life, the sense of stigma and degree of self-acceptance in depressed patients.

To explore the effect of comprehensive nursing on pain, anxiety and malnutrition of hepatitis B patients.
Totally 100 cases of hepatitis B patients received treatment in our hospital from July 2017 to July 2018 were divided into a study group (64 cases) and a control group (36 cases) for comprehensive nursing and routine nursing. The liver function, nutritional indexes, cognition of relevant nursing knowledge, VAS score, HAMD and HAMA scores, QOL score, total effective rate and incidence of adverse reactions were detected.
Compared with the control group, the study group had lower liver function indexes and higher nutrition indexes, suggesting that the liver function of patients in the study group recovered better. Besides, the VAS score of the study group was lower, suggesting better pain relief in the study group. Moreover, the study group had higher scores of related nursing knowledge and lower scores of HAMD and HAMA, indicating that the nursing method in the study group was more effective in reducing depression and anxiety. Higher QOL score, higher total effective rate and lower incidence of adverse reactions of the study group revealed that the nursing mode adopted in this group was better for the recovery of patients.
Comprehensive nursing can effectively alleviate the pain of hepatitis B patients, relieve their anxiety and other negative emotions, and improve their malnutrition.

The purpose of this research is to probe the mechanism of Jatrorrhizine (JAT) improving Aβ 25-35-induced nerve cell injury through the miR-223-3p/HDAC4 axis.
SH-SY5Y cells were treated with Aβ 25-35 to simulate nerve injury in the pathogenesis of Alzheimer's disease (AD), and JAT-treated SH-SY5Y cells were assessed for HDAC4 and miR-223-3p. The HDAC4 and miR-223-3p levels were tested by qRT-PCR. Proliferation was determined through MTT. TKI-258 in vivo Apoptosis was assessed by flow cytometry, and the related indexes of oxidative stress (OS) were examined by an OS kit.
Compared with AD group, OD value increased, apoptosis rate decreased, and OS was inhibited in the AD+JAT group (all P<0.05). In SH-SY5Y cells, miR-223-3p can specifically inhibit the HDAC4 expression. The miR-223-3p expression increased and HDAC4 decreased after JAT acted on SH-SY5Y cells stimulated by Aβ 25-35 (all P<0.05). The addition of over-expression HDAC4 vector or miR-223-3p inhibitor could inhibit proliferation, and promote apoptosis and OS on the basis of JAT (all P<0.05). In addition, over-expressing miR-223-3p can suppress over-expressed HDAC4's effects on proliferation, apoptosis, and OS of SH-SY5Y cells (all P<0.05).
JAT can improve the nerve injury induced by Aβ 25-35 by up-regulating miR-223-3p and inhibiting the HDAC4 expression, suppress apoptosis and OS, and induce proliferation. This research further clarified the mechanism of JAT in AD.
