Objective To provide the evidence for the development of personalized health education courses for twin pregnant women.We explored the health education and psychosocial demand of twin pregnant women from the perspective of social ecosystem theory.Methods By purposive sampling,18 twin pregnant women hospitalized in the twin medical center of a tertiary A hospital in Shenyang from January to March 2023 to conduct for semi-structured interviews,and Colaizzi's 7-step analysis method was used to sort out and analyze the data.Results 3 themes were extracted from the health education and psychosocial needs of twin pregnant women.Microsystem:the content needs of twin pregnant women's health education(the guidance needs of nutrition intake and weight growth;the needs for fetus health monitoring guidance;the cognitive needs of twin pregnancy complications;the needs for health education knowledge related to puerperium and the diversification of the choice of teaching methods).Mesosystem:the emotional support needs of twin pregnant women during prenatal and puetperal(the needs of family support and peer education support).Macrosystem:seeking social support and network information support(the demand of community support;the needs of information related to twin pregnant women's hierarchical management system and maternal fetal medical referral process and the needs for network health education information).Conclusion The women with twin pregnancy have different needs for health education content in each stage of pregnancy and puerperium,and there are urgent needs for emotional support and social support.Clinical nurses should construct health education courses according to the needs of twin women,and innovate in content and form,so as to improve the self-care ability of twin pregnant women and the knowledge level of family caregivers,and improve the pregnancy outcome.

Objective: To explore and compare the preventive effect of using letrozole and gonadotropin-releasing hormone (GnRH) antagonist during luteal phase of patients at high risk for ovarian hyperstimulation syndrome (OHSS). Methods: A total of 99 infertile women undergoing in vitro fertilization and embryo transfer or intracytoplasmic sperm injection with high risk for OHSS were enrolled in this randomized controlled trial.The letrozole group (n=51) received letrozole of 7.5 mg daily for 3 days;the GnRH antagonist group (n=48) were given cetrorelix of 0.25 mg subcutaneously daily for 3 days. Both groups received support therapy combined with embryo cryopreservation. The incidence of OHSS was surveyed. And the serum concentration of estradiol, LH and progesterone on days 3, 5 and 8 after oocytes retrieval were measured. Results: There were no statistical differences in terms of baseline characteristics of patients and outcomes of controlled ovarian hyperstimulation between the two groups.The incidence of moderate and severe OHSS was found no significantly difference between letrozole group [11.8%(6/51)] and GnRH antagonist group [10.4%(5/48);P>0.05]. The estradiol concentration of the indicated days on days 3,5 and 8 after oocytes retrieval in letrozole group and GnRH antagonist group were (1 417±3 543) versus (15 210±9 921) pmol/L, (1 692±4 330) versus (18 680±11 567) pmol/L, (239±336) versus (3 582±5 427) pmol/L, respectively;compared with GnRH antagonist group, the estradiol level was significantly lower in the letrozole group (all P<0.01). The luteinizing hormone level in the letrozole group were (0.46±0.40), (0.56±0.55)and (0.67±0.58) U/L on days 3,5 and 8 after oocytes retrieval, which were significantly higher than those of GnRH antagonist group [(0.28±0.28), (0.30±0.19) and (0.45±0.37) U/L, respectively; all P<0.05]. There was no obvious differences on progesterone levels between letrozole group and GnRH antagonist group (all P>0.05),and on days 8 after oocytes retrieval,the level of progesterone in each group were significantly lower than those on day 3 and 5 after oocytes retrieval (P<0.05). Conclusion Letrozole has the same efficiency as GnRH antagonist for the prevention of OHSS, faster and cheaper to use, but its efficacy seems not to be related to the suppression of steroidogenic during the luteal phase.

Objective:To explore the development trend of the combination of medical treatment and endowment and nursing by analyzing the keywords related to the combination of medical treatment and endowment and nursing in China from 2005 to 2017.Methods:Relevant articles about the combination of medical treatment and endowment which were published up to April 22, 2018 were retrieved from Wanfang, CNKI and VIP databases, and descriptive statistical methods were used to analyze the publication sources, number of keywords, word frequency, value of popularity, word meaning, etc.Results:Totally 5 704 articles were identified, and 1 655 were left after screening. The research on nursing started late among all researches on the combination of Chinese medical treatment and endowment, and there were few literatures, which had not received widespread attention from nursing journals. The proportion of Chinese nursing-related research in the combination of medical treatment and endowment was low. The keyword most concerned about was "senior caregivers". There was a lacking of technical and professional nursing research as well as specific discussions related to home care for the elderly.Conclusions:We should promote multi-angle and multi-level systematic nursing research, strengthen professional research in the combination of medical treatment and endowment and home care for the elderly, and provide technical support and practical basis for improving China's knowledge system of "the combination of medical treatment and endowment", and achieving a win-win situation for healthcare providers, caregivers, nurses and patients.

Objective To compare the safety and efficacy of the caudal block and Total Intravenous Anesthesia (TIVA) for transrectal ultrasound (TRUS) guided prostate biopsy.Methods 60 elderly patients with transrectal ultrasound guided transperineal prostate biopsy were randomized into Group A and Group B.Patients in Group A received ultrasound guided caudal block (0.33％ ropivacaine 15 ml) and patients in Group B received TIVA.In operation room (T1),immediately before operation (T2) and at the end of operation (T3),mean artery pressure (MAP),heart rate (HR),breathing rate (BR) and pulse oxygen saturation (SpO2) were recorded.The patients in two groups were rated the level of mini-mental state examination (MMES) at 2 h,8 h and 24 h after operation.Complications during the whole study period were also evaluated.Results The values of MAP,HR and BR of T1 in group B were significantly lower than those at T2 (P＜0.05),and were lower than those in the group A (P ＜0.05).The MMSE value in group A [2 h (25.66 ± 1.71) and 8 h (26.13 ± 1.52)] was significantly higher than that in group B [2 h (27.96 ± 1.71) and 8 h (29.01 ± 0.77)] at after operation (P ＜ 0.05).The rate of usage of ephedrine (13％) and assisted ventilation (20％) in group B was higher.No significant differences were detected in side effects between the two groups.Conclusions Caudal block provides better anesthesia than TIVA for TRUS guided prostate biopsy without an increase of side effects,and it may be safely used during ambulatory surgery.

Objective To investigate the effects of α-lipoic acid(ALA)on 6-hydroxydopamine(6-OHDA)-induced autophagy in human neuroblastoma(SH-SYSY)cells and its possible mechanisms.Methods SH-SYSY cells were divided into 5 groups:blank control group (group A),ALA group (group B),6-OHDA group(group C),ALA+6-OHDA group(group D),and rapamycin(RAPA)group (group E).The cell viability,cell apoptosis,and oxidative stress were assayed and analyzed in A-D group.The expression of autophagy-related proteins LC3-Ⅱ,AMP-activated protein kinase(AMP-K),phosphorylated AMPK (p-AMPK),the mammalian target of rapamycin (mTOR) and p-mTOR were detected by Western blot in A-E group.Results Compared with the blank control group,the 6-OHDA group significantly reduced the cell viability(P ＜ 0.01) and p-mTOR protein expression (P ＜0.05),and increased the cellular apoptosis rate(P＜0.01),oxidative stress level(P ＜0.01),LC3-Ⅱ protein expression(P＜0.05,with the highest level at 6 h after treatment),and p-AMPK protein expression(P＜＜0.05).There was no significant difference in these indices between ALA group and the blank control group.Compared with 6-OHDA group,ALA+ 6-OHDA group showed that the cell viability(P ＜ 0.01) and p-mTOR protein expression (P ＜ 0.05) were increased,while the cellular apoptosis rate(P＜0.01),oxidative stress level(P＜0.01),LC3-Ⅱ protein expression(P ＜0.05),and p-AMPK protein expression (P ＜ 0.05)were decreased.Conclusions The 6-OHDA can induce oxidative stress and autophagy in SH-SY5Y cells and decrease the cell viability.ALA can alleviate the 6-OHDA-induced cell injury possibly by inhibiting autophagy via AMPK/mTOR pathway.

In this study, a multiplex RT-PCR method was developed for detection of seven diarrhea-associated porcine viruses, including porcine teschovirus (PTV), porcine sapovirus (PSV), porcine deltacornavirus (PDCoV), porcine kobuvirus (PKV), porcine sapovirus (PSaV), porcine astrovirus (PAstV) and porcine torovirus (PToV). A total of 419 samples were screened by this method and results showed that PKV had the highest positive rate of 26.98%?45.79% and its mixed infection rate reached 9.52%-18.54%. On account of high positive rate of PKV and its important role in diarrhea disease, complete genomic sequences of three PKV positive samples were further sequenced. Three PKV labeled as PD-PKV, JS-PKV and CM-PKV were classified into porcine kobuvirus genus and had far genetic distance with other kobuviruses. The complete genome homologies among them were 88.1%-89.1%. CM-PKV had the highest identity with the Chinese strain JS-02a-CHN/2013 reported in 2013 while JS-PKV and PD-PKV were most closed to the K-30-HUN/2008/HUN strain reported in Hungary in 2008. This illustrates the significant genetic differences of the different PKV isolates in Shanghai while its relationship with the viral pathogenicity still needs to be explored. This research provides references for further understanding the prevalence of PKV and its role in swine diarrhea.

We aimed at analyzing the structure of extracellular polysaccharide A from Grifola frondosa (EXGFP-A) and testing its immunomodulatory activity. Structural analysis shows that EXGFP-A was a contained α-D-glucoside bond and pyranose ring. GC analysis reveals that EXGFP-A was mainly composed of rhamnose, arabinose, xylose, mannose, glucose, galactose, by the molar ratio of 0.28:0.31:0.30:0.06:7.98:0.61. The results of MTT(3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay indicates when EXGFP-A was at a concentration of 80 μg/mL and treatment time of 48 h, RAW264.7 cells proliferation index reached a maximum of 137.5%. Meanwhile, the AO staining showed that EXGFP-A activated RAW264.7 cells and improved the level of intracellular nucleic acid metabolism. In addition, in a certain range of concentration, EXGFP-A was able to increase the release of NO in RAW264.7 cells, and upregulate the mRNA expression of immunological factor TNF-α, IL-1β, IL-6, IL-12, IFN-γ and iNOS of RAW264.7 cells. Our results confirm that EXGFP-A had immunomodulatory activity. Our findings provided scientific basis for the structural analysis and application of Grifola frondosa polysaccharide.

Objective To investigate the clinical efficacy of Lu’s warm needling in treating perimenopausal syndrome.Methods Sixty patients with perimenopausal syndrome were randomly allocated to treatment and control groups, 30 cases each. The treatment group received Lu’s warm needling and the control group, conventional acupuncture. The scores of Kupperman Index (KI), Pittsburgh Sleep Quality Index (PSQI) and Hamilton Depression Scale (HAMD), and serum estrogen (E2), follicle stimulating hormone (FSH) and luteal hormone (LH) were observed before and after treatment. The clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 80.0% in the treatment group and 53.3% in the control group; there was a statistically significant difference between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the KI score in the two groups (P<0.01). There was a statistically significant difference in pre-/post-treatment KI score difference value between the treatment and control groups (P<0.05). There were statistically significant pre-/post-treatment differences in serum LH, FSH and E2 contents in the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in the Hamilton Depression Scale score and the Pittsburgh Sleep Quality Index score in the two groups (P<0.01, P<0.05). There was a statistically significant post-treatment difference in the Hamilton Depression Scale score between the treatment and control groups (P<0.05).Conclusion Lu’s warm needling is an effective way to treat perimenopausal syndrome.

Bacterial cell division is strictly regulated in the formation of equal daughter cells. This process is governed by a series of spatial and temporal regulators, and several new factors of interest to the field have recently been identified. Here, we report the requirement of gluconate 5-dehydrogenase (Ga5DH) in cell division of the zoonotic pathogen Streptococcus suis. Ga5DH catalyzes the reversible reduction of 5-ketogluconate to D-gluconate and was localized to the site of cell division. The deletion of Ga5DH in S. suis resulted in a plump morphology with aberrant septa joining the progeny. A significant increase was also observed in cell length. These defects were determined to be the consequence of Ga5DH deprivation in S. suis causing FtsZ delocalization. In addition, the interaction of FtsZ with Ga5DH in vitro was confirmed by protein interaction assays. These results indicate that Ga5DH may function to prevent the formation of ectopic Z rings during S. suis cell division.
