Objective To observe the effects of the compatibility of Radix Astragali and Radix Angelicae Sinensis in different proportion on hemodynamic and balance of Th1/Th2 cells of Qi deficiency and blood stasis rat model. Methods Qi deficiency and blood stasis rats were caused by restricted diet, forced swimming and norepinephrine subcutaneous injecting, and treated by compatibility of Radix Astragali and Radix Angelicae Sinensis in different proportion of 5∶1, 3∶1, 1∶1 and 1∶2 for 21 days. The indexes of hemorheology were detected with hemorheological analyser, and the level of IFN-γand IL-4 in serum were tested by ELISA. Results Compared with model group, the compatibility of Radix Astragali and Radix Angelicae Sinensis in proportion of 1∶1, 3∶1 and 5∶1 groups reduced the low shear blood viscosity. The spleen index of model group decreased, and compatibility of Radix Astragali and Radix Angelicae Sinensis in 5∶1 proportion group increased spleen index. The level of IL-4 increased and IFN-γ decreased in the serum of model group, the compatibility of Radix Astragali and Radix Angelicae Sinensis in proportion of 3∶1 group increased the level of IFN-γ. Astragalus angelica 5∶1 group decreased the level of IL-4 and increased the level of IFN-γ. Conclusion The compatibility of Radix Astragali and Radix Angelicae Sinensis can improve hemorheology, adjust the balance of Th1/Th2 cells of Qi deficiency and blood stasis rats. The effects were better when Radix Astragali’s dosage greater than that of Radix Angelicae Sinensis, and the group of 5∶1 proportion was the best.

The progressive injury of retinal ganglion cells ( RGCs) is a common occurrence in several eye diseases, which ultimately may lead to irreversible blindness. Currently, there are still no effective or ideal treatments for it in practice, however some recent studies show that stem cell transplantation may provide a promising new idea for neuroprotection and replacement of retinal ganglion cells. This paper will review the research progress of stem cell transplantation-based treatment.

Objective To investigate the clinical efficacy of heat-sensitive point thunder-fire moxibustion in treating knee osteoarthritis (KOA). Methods One hundred and forty-eight KOA patients were randomly allocated to treatment and control groups, 74 cases each. The treatment group received heat-sensitive point thunder-fire moxibustion and the control group took diclofenac sodium enteric-coated tablets. The Visual Analogue Scale (VAS) score, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and 50 yards fastest walking time were observed in the two groups before and after 30 days of treatment. The clinical therapeutic effects were compared between the two groups. Results There were statistically significant pre-/post-treatment differences in the VAS score and WOMAC subscores in the two groups (P<0.01). There was a statistically significant pre-/post-treatment difference in 50 yards fastest walking time in the treatment group (P<0.05). There were statistically significant post-treatment differences in the VAS score, the WOMAC score and the WOMAC pain and stiffness scores between the treatment and control groups (P<0.01). There were statistically significant differences in the VAS and WOMAC scores at three months after treatment between the treatment and control groups (P<0.01). The total efficacy rate was 95.9%at the end of treatment and 95.6%at three months after treatment in the treatment group, and 86.1%at the end of treatment and 86.8%at three months after treatment in the control group; there were statistically significant differences between the two groups (P<0.05). Conclusion Heat-sensitive point thunder-fire moxibustion is an effective way to treat knee osteoarthritis.

Visfatin was recently reported as an adipokine and was found to exert insulin-mimicking effects.The results showed that the expression of visfatin parallelled with obesity and insulin resistance in long term high fat chow-fed rats.The expression of visfatin mRNA was decreased and the insulin resistance improved after rennin-angiotensin system was blocked.Visfatin may play an important role in the pathogenesis of insulin resistance.

OBJECTIVE: To explore the role of the innate immune factors TLR2 and TLR4 in the pathogenesis of chronic rhinosinusitis (CRS) by detecting their expression in different clinical types of CRS and the normal control group. METHOD: Immunohistochemistry was used to detect the expression of TLR2 and TLR4 respectively in 21 cases (chronic rhinosinusitis with nasal polyps, CRSwNP) group, 15 cases (chronic rhinosinusitis without nasal polyos, CRSsNP) group, 11 cases recurrent CRSwNP group and 13 cases control group. Positive cells were counted under the microscope artificially, Mann-Whitney U analysis was applied for the ranked data, and one-way anova analysis was adopted to analyze the experimental group and control group. RESULT: (1) TLR2 and TLR4 expression had the same characteristics. Expression mainly concentrated in parts of the whole layer of epithelial basement membrane, cytoplasm of glandular cells, very few inflammatory cells such as monocytes and plasma cells in the cytoplasm, sometimes unknown cell nuclei positive expression. (2) The glandular cells were stained manual counting and color grading. TLR2 and TLR4 packet application Wilcoxon rank test Mann-Whitney U test analysis was not statistically significant (P > 0.05), measurement data within the group variance statistical difference between the groups (P < 0.05). CONCLUSION The Nasal mucosa can produce the innate immune factors TLR2 and TLR4. The different expression of TLR2 and TLR4 in the various clinical types of CRS suggests that they play the certain role in the pathogenesis of CRS.

Objective: To learn the influencing factors for self-violent thoughts and behaviors among the ninth-grade students in Jiangbei District of Ningbo, so as to provide the basis for carrying out psychological intervention. Methods: The ninth-grade students in a junior high school each of the six streets ( towns ) in Jiangbei District were recruited by multi-stage cluster sampling method from October to November 2018. A self-designed questionnaire was used to investigate the general information, life style, psychological condition, self-violent thoughts and behaviors in the latest year. Multivariate logistic regression model was used to analyze the influencing factors for self-violent thoughts and behaviors. Results: A total of 1 300 questionnaires were issued and 1 238 valid ones were recovered, with an effective rate of 95.23%. The prevalence rates of self-violent thoughts and behaviors among the ninth-grade students were 16.88% and 8.48%.

Conclusion Drinking, family relationship, bullying, and mental health problems such as sense of despair and anxiety were associated with the self-violent thoughts and behaviors of ninth-grade students.

Objective:To summarize the establishment and management experience of extracorporeal membrane oxygenation (ECMO) rapid response team, and explore a more efficient rescue mode.Methods:From January 2015 to September 2020, 85 patients treated with ECMO in Affiliated Hospital of Qingdao University were selected as the research objects. Thirty-eight patients treated with conventional ECMO from January 2015 to December 2019 were selected as the control group, and 47 patients treated with ECMO rapid response team from January 2020 to September 2020 were selected as the experimental group. The differences in team preparation time, catheterization time, treatment success rate, incidence of complications and equipment failure frequency between the two groups were compared.Results:There were no significant differences in gender, age or disease types between the two groups. The team preparation time and catheterization time of the experimental group were significantly shorter than those of the control group [team preparation time (minutes): 31.79±6.10 vs. 67.16±30.49, catheterization time (minutes): 40.62±7.13 vs. 84.89±19.29], and the incidence of complications was significantly lower than that of the control group [4.3% (2/47) vs. 21.1% (8/38)], and the differences were statistically significant (all P < 0.05). Conclusion:ECMO rapid response team can shorten the rescue preparation time, reduce the occurrence of complications, improve the team treatment efficiency, and provide ideas for emergency and critical patients.

Twelve populations of Inula lineariifolia were used as materials to measure morphological characteristics, photosynthetic parameters and chemical constituents. It aims to provide a theoretical basis for germplasm resources evaluation. The results showed that I. lineariifolia had relatively rich morphological diversity, there were significant differences of morphological characteristics, photosynthetic parameters and chemical constituents among populations. There was positive correlation on morphological characteristics and P(n). Twelve populations were divided into three-type. The three populations of Xuyi, Mingguang and Fengyang were of narrower-longer leaf, bigger biomass,better photosynthetic and higher chemical constituents. Then they were classified for a similar group. It proved that the three populations were more suitable for cultivation and promotion.
