[Analysis of regularity of acupoint selection and compatibility of acupuncture in the treatment of postpartum depression].

OBJECTIVE: To analyze the regularity of acupoint selection, and compatibility of acupuncture in the treatment of postpartum depression. METHODS: Articles both in English and Chinese published in databases of CNKI, Wanfang, VIP, Chinese biomedical literature database (SinoMed), PubMed, Embase, Cochrane Library from the inception to February of 2021 were retrieved by using key words "acupuncture" or "moxibustion" or "electroacupuncture" or "acupoint application" or " acupoint burying" or "acupoint injection" or "fire needling" and "postpartum depression" or "puerperal depression". The frequencies of selected acupoints and meridians were counted by using data mining technology, and the points with high frequency were analyzed by cluster analysis. RESULTS: A total of 42 articles were included, containing 65 prescriptions and 80 points. The highest frequency of acupoints were Baihui (GV20), Sanyinjiao (SP6), Taichong (LR3), Neiguan (PC6), Zusanli (ST36) and Shenmen (HT7). The most frequently selected channels were Bladder Meridian, Governor Meridian and Liver Meridian. Among the specific points, intersection points, five-shu points, yuan-source points and back-shu points were widely used. Through cluster analysis, four effective cluster groups ï¼»GV20-SP6, LR3-PC6, Xinshu (BL15)-Ganshu (BL18)-Pishu (BL20)-Guanyuan (CV4), Hegu (LI4)-Qihai(CV6)-Qimen (LR14)ï¼½ were obtained, as well as a group of main points (GV20-SP6-LR3-PC6-ST36-HT7) and two groups of matching points ï¼»LI4-CV6-LR14 and BL15-BL18-BL20-CV4-Sishencong (EX-HN1)ï¼½. CONCLUSION: Through data mining technology, this paper summarized the acupoint selection and compatibility law of acupuncture in the treatment of postpartum depression, focusing on regulating Qi, blood and spirit, so as to provide reference for guiding the clinical acupuncture treatment and scientific research of postpartum depression.

Influence of transitional nursing on the compliance behavior and disease knowledge of children with purpura nephritis.

BACKGROUND: Purpura nephritis, also called Henoch-Schönlein purpura nephritis, is a systemic disease with small dead vasculitis as the main pathological change. AIM: To observe the influence of transitional nursing activities on the compliance behaviors and disease knowledge of children with purpura nephritis. METHODS: A total of 82 children with purpura nephritis were included and divided into a general nursing group (41 children) and transitional nursing group (41 children) using the envelope method. The general nursing group received routine nursing care, while the transitional nursing group received transitional nursing care. The behaviors, knowledge of the disease, and self-management ability of the two groups were evaluated after nursing care was provided. RESULTS: The scores of four items (self-care ability, self-responsibility, health knowledge level, and self-concept) in the transitional nursing group were significantly higher than those in the general nursing group. CONCLUSION: Transitional nursing can directly improve the disease knowledge level and self-management ability of children with purpura nephritis and effectively reduce complications.

The type III secretion system (T3SS) of Chlamydophila psittaci is involved in the host inflammatory response by activating the JNK/ERK signaling pathway.

Chlamydophila psittaci (C. psittaci) is a human zoonotic pathogen, which could result in severe respiratory disease. In the present study, we investigated the role and mechanism of the type III secretion system (T3SS) of C. psittaci in regulating the inflammatory response in host cells. C. psittaci-infected THP-1 cells were incubated with the specific T3SS inhibitor INP0007, inhibitors of ERK, p38, or JNK, and the levels of inflammatory cytokines were analyzed using Q-PCR and ELISA. The levels of ERK, p38, and JNK phosphorylation were analyzed by Western blot. Our results verified that INP0007 inhibited chlamydial growth in vitro, but the coaddition of exogenous iron completely reversed the growth deficit. INP0007 inhibited the growth of C. psittaci and decreased the levels of IL-8, IL-6, TNF-α, and IL-1ß. Exogenous iron restored the chlamydial growth but not the production of inflammatory cytokines. These results demonstrated that the expression of inflammatory cytokines during infection was associated with the T3SS which reduced by incubation with ERK and JNK inhibitors, but not with p38 inhibitor. We concluded that the T3SS elicited inflammatory responses by activating the JNK or ERK signaling pathways in the infection of C. psittaci.

[Effect of the drug-resistant attenuated Bacillus proteus on CD80 and CD86 protein expression in peripheral blood dendritic cells of hepatitis B patients].

OBJECTIVE: To explore the effect of the drug-resistant attenuated Bacillus proteus on the protein expression of CD80 and CD86 in peripheral blood dendritic cells (DCs) of hepatitis B patients. METHOD: Peripheral blood monocytes were isolated from HBV-infected patients and the DCs were separated and induced to differentiate in vitro. The expression of CD80 and CD86 proteins on cultured DCs were examined using flow cytometry. RESULTS: The expression rate of CD80 and CD86 of chronic hepatitis B patients increased significantly (P=0.000), while the positive expression rate of CD80 and CD86 showed no obvious variation in healthy individuals (P=0.185 and P=0.118, respectively). CONCLUSIONS: Bacillus proteus can significantly increase CD80- and CD86-positive cell percentage in peripheral blood DCs of HBV-infected patients, but has no such an effect in healthy individuals.

[An electron microscope observation for the abnormal ultrastructure of the connecting piece in human spermatozoa from infertile painters].

OBJECTIVES: To investigate possible abnormalities of the sperm neck in eight infertile painters observed by transmission electron microscope. METHODS: Spermatozoa from 8 infertile painters (21-32 years old) were observed by transmission electron microscope. RESULTS: The abnormalities of the connecting piece could be divided into 6 types, among which the anomaly of the connecting piece concomitant with a true nuclemalamic condition was the most serious. CONCLUSIONS: The abnormalities may be related to expression obstacles of nuclear genome and mitochondrial genome, and to anomalous cellular signal transduction during spermiogenesis as well.
