Background and purpose:Edible fungi has shown powerful potential in health care. This study aimed to explore the anti-tumor and immunoenhancement effects of combination of extraction from edible fungi. Methods:C26 cells has been xenografted into mice, and the animal models were randomly divided into control group, prevention group, treatment group and cyclophosphamide group. Mice were given the combination of extraction from edible fungi every day after vaccination of C26 cells into mice, except the prevention group which has been given the combination of extraction from edible fungi two weeks before vaccination. Two weeks after being planted, all the mice were killed and the tumor inhibition rates were studied. The immune function was measured by T lymphocyte transforming assay and NK killing assay. Results:There were signif icant difference in terms of tumor weight between prevention group and control group. The prevention group mice display improved T lymphocyte transforming assay and NK killing ability. Conclusions:The combination of extraction from edible fungi has remarkable inhibitory effects on C26 carcinoma in mice and can enhance immunity against mice with C26 carcinoma.

Objective:
This study is the first to adopt a cultural and contextual coping model to examine the impact of forbearance coping on compliance and psychological health and unravel the psychosocial mediator and moderator among community-dwelling residents in the post-pandemic era in China.
Methods:
A multistage cluster convenience sampling strategy was conducted to recruit 402 community-dwelling residents of ten cities in Guangdong province who completed an online survey measuring forbearance coping, anti-pandemic compliance behaviours, family resilience, community resilience and psychological distress.
Results:
The study results showed an unexpected negative influence of forbearance coping on psychological distress. Nevertheless, forbearance coping facilitated personal compliance with coronavirus disease-2019 mitigation measures and improved psychological health. More importantly, meaning-making of adversity within families partially mediated the negative effect of forbearance on mental health only when respondents perceived higher levels of community resilience.
Conclusion
This study is the first to apply the cultural and contextual model of coping to Chinese individuals during a significant public health crisis. It expands the model by uncovering mechanisms like behavioural compliance and family meaning-making, and highlights the moderating role of community resilience. The findings emphasize the importance of building resilient communities and supporting mental health, providing evidence for future policy interventions and pandemic/disaster prevention measures in China.

Objective: To compare the therapeutic effects of two different moxibustion methods both with tai-yi moxa stick in treating primary dysmenorrhea. <br> Methods: Forty-three patients were randomized into two groups by the random number table according to their treatment orders. The causalgic group was intervened by causalgic stimulation with tai-yi moxa stick while the tepid group was treated by mild thermal stimulation with tai-yi moxa stick. Shiqizhui (EX-B 8) was selected for both groups. Visual analogue scale (VAS) was used for observation before and during the treatment by every 10 min to compare the clinical efficacies between the two groups. <br> Results: Before treatment, there was no statistically significant difference in pain intensity between the two groups (P>0.05). After treatment, both groups achieved significant improvements in pain intensity (P<0.05), but the inter-group difference in pain intensity was still statistically insignificant (P>0.05), but the difference was enlarged comparing with that before treatment. The pain relief during the first 10 min of treatment was slower in the causalgic group than that in the tepid group. However, during the later 20 min, the pain relief in the calsalgia group gradually outpaced that in the tepid group. <br> Conclusion: The two moxibustion methods with tai-yi moxa stick both have a good instant analgesic effect in treating primary dysmenorrhea. For patients with primary dysmenorrhea, if 30 min is regarded as the treatment time, mild stimulation was suggested to be used for the first 10 min, and causalgic stimulation for the later 20 min to achieve a better curative effect.

OBJECTIVETo study the microstructure of the Ag-nHA-nTiO2/PA66 membrane and investigate its biocompatibility.
METHODSThe microstructure of Ag-nHA-nTiO2PA66 membrane and e-polytetra fluoroethylene (e-PTFE) membrane were observed by light microscope and scanning electron microscope(SEM). MG63 osteoblast-like cells were cultured on the two kinds of membrane and blank group. The cell proliferation was checked by methyl thiazolyl tetrazolium (MTT) method and alkaline phosphatase (ALP) activity was detected by enzyme linked immunosorbent assay (ELISA). The adhesion and proliferation of the cells on the two kinds of membrane was observed by SEM.
RESULTSThe Ag-nHA-nTiO2/PA66 membrane was composed of the obverse face and the opposite face. The obverse face was porous and the opposite face was smooth. Microstructures of the obverse and the opposite face of the e-PTFE membrane were same. The e-PTFE membrane showed many tiny lined cracks in elliptic structure. MTT assay and ALP measurement showed that there were no significant difference between each of the two membrane groups and the blank (P > 0.05). The adhesion and proliferation of cells on the Ag-nHA-nTiO2/PA66 membrane were better than the e-PTFE membrane.
CONCLUSIONAg-nHA-nTiO2/PA66 membrane has no negative effects on the growth of osteoblast-like cells. Ag-nHA-nTiO/PA66 membrane is biocompatible and its microstructure is appropriate as a guided bone regeneration materials.

Objective To investigate the functions of FABP5 in the carcinogenesis and development of cervical cancer. Methods The expression of FABP5 was detected in several cervical cancer cell lines (C33A, Siha, Caski, HeLa and HCC94), 206 cases of cervical cancer tissues with stageⅠa2?Ⅱa2 and 40 cases of normal cervical tissues by real?time PCR and Western blotting. Then, the cells were infected with lentivirus?mediated siRNA?targeting FABP5. CCK?8 cell proliferation, colony formation, wound healing and transwell assays were used to investigate the effects of FABP5 on in vitro cell proliferation, migration and invasion. And in vivo xenograft model and lung metastasis model were used to observe the transplanted tumor growth and metastasis in female athymic nude mice. Furthermore, the total protein and RNA were extracted from the primary xenografts to determine the expression levels of FABP5, metalloproteinase?2 and metalloproteinase?9 using Enzyme linked immunosorbent assay ( ELISA ), real?time PCR and Western blotting.Results FABP5 expression was found to be significantly unregulated in cervical cancer tissues than that in normal cervical tissues ( P<0.05). Compared with the Siha?NC group and uninfected group, the expression of FABP5 mRNA and protein in Siha?FABP5?RNAi group was significantly inhibited along with the decrease of cell proliferation, colony formation, wound healing and invasion ability. The clone formation rates of Siha cells in uninfected group, Siha?NC group and Siha?FABP5?RNAi group were (84.6± 4.5)%, (84.6±5.1)% and (21.2±2.6)%, respectively. Moreover, the transwell assay showed that invasive cells in three groups were (72.8±4.7)/HPF, (72.6± 3.3)/HPF and ( 21.4± 2.3)/HPF, respectively. All of the difference was statistically significant (P<0.05). Furthermore, FABP5 silencing significantly reduced tumor growth and lung metastases in nude mice in vivo ( P<0.001). The subcutaneously xenografted volume in uninfected group, Siha?NC group and Siha?FABP5?RNAi group was (921.4±63.0) mm3, (1 021.4±56.0) mm3 and (139.6±36.0) mm3, respectively. The real?time quantitative PCR results showed that the relative expression levels of MMP?2 and MMP?9 mRNA were 1.00±0.10 and 1.00±0.10, 1.00±0.10 and 1.00±0.10 as well as 0.34±0.13 and 0.38±0.17 in xenografted tumor tissues of uninfected group, Siha?NC group and Siha?FABP5?RNAi group, respectively. MMP?2 and MMP?9 was significantly downregulated after FABP5 inhibition(P<0.05). Additionally, the protein expression trend of MMP?2 and MMP?9 in three groups was consistent with the mRNA levels. Conclusion FABP5 might promote the carcinogenesis and metastasis of cervical cancer via up?regulating MMP?2 and MMP?9.
