Objective To investigate the effect of reinforced Decoction of Angelicae Sinensis for enriching blood (RDAEB) on the immunity of immunosuppressed mice induced by cyclophosphamide (Cy). Methods Mice were given RDAEB through stomach perfusion for 10 d(50 mg/d). Then, RBC-C3bR rate,RBC-IC rate( as the indexes of erythrocyte immunity)and E-rosette forming rate,acidic α-naphthyl acetate esterase positive rate, lymphocyte transformation rate (as the indexes of cellular immunity) of mice were tested.Results RBC-C3Br rate, RBC-IC rate,E-rosette forming rate, acidic α-naphthyl acetate esterase positive rate and lymphocyte transformation rate in the Cy-RDAEB group were markedly higher than those in the Cy group (P<0. 01 ),and returned to the levels of normal group. Conclusion RDAEB is effective in recovering and enhancing cellular and erythrocyte immunity of immunosuppressed mice.

Objective:To investigate whether FcγRⅡb rs775 single nucleotide polymorphism confers susceptibility to Hashimoto′s thyroiditis and its impact on expression of FcγRⅡb protein on B cell surface.Methods:A total of 187 Hashimoto′s thyroiditis patients(HT group) were enrolled, including 46 males(24.60%) and 141 females(75.40%), with a median age of 43(32, 53) years, and 187 healthy controls(conrol group), including 62 males(33.16%) and 125 females(66.84%), with a median age of 41(31, 51) years. The peripheral blood of two groups were sequenced, genotype and allele frequencies distribution of FcγRⅡb rs775 T>C were compared with clinical parameters as strata between the two groups. At the same time, the expression of inhibitory receptor FcγRⅡb on B cell surface was detected using flow cytometry.Results:Compared with control group, the mutant homozygous CC genotype was obviously enrichment in HT group( OR=3.321, 95% CI 1.175-9.386, P=0.018), and the proportion of CC genotype increased in male of HT group( P=0.076). However, there is no significant difference in genotype and allele frequencies between control group and HT group after stratification by sex. In addition, the percentage of FcγRⅡb on B cell surface decreased significantly in HT group( P=0.029). Conclusion:There was no significant correlation between FcγRⅡb polymorphism and the down-regulation of FcγRⅡb protein on B cell surface in Hashimoto′s thyroiditis patients, and FcγRⅡb can be a predisposed factor for Hashimoto′s thyroiditis.

Objective:To investigate the gut microbiota composition in subclinical hypothyroidism and euthyroidism patients with Hashimoto′s thyroiditis, and its relationship with clinical indicators and inflammatory factors.Methods:A total of 48 patients diagnosed with Hashimoto′s thyroiditis and 28 healthy controls(HC group) were enrolled from Henan Provincial People′s Hospital from July 2019 to March 2022 in this cross-sectional study. According to thyroid function, 18 patients with Hashimoto′s thyroiditis were divided into subclinical hypothyroidism group(SH group) and 30 patients in euthyroidism function group(Eu group). Fecal microbial composition was detected by 16S rRNA sequencing technology, and peripheral blood was collected to test clinical indicators and inflammatory factors.Results:Compared with HC group, there were significant differences in α and β diversity of gut microbiota in SH and Eu group( P=0.045, P=0.037). At the phylum level, Firmicutes, Bacteroidota, and Proteobacteria were the dominant phylum in the three groups. At the genus level, the abundance of 4 bacterial genera increased gradually in HC group, Eu group, and SH group, including Streptococcus, Comamonas, Elizabethkingia, Achromobacter. However, the abundance of the other 9 genera decreased gradually, such as Subdoligranulum, Coprococcus, Oscillospirales_ UCG-010, Clostridia_ UCG-014, Oscillospiraceae_ UCG-002, Alistipes et al. In addition, the level of serum B-cell activating factor was positively correlated with several bacterial genera such as Achromobacter, Streptococcus, Intestinibacter et al. Conclusion:There are differences in the gut microbiota structure of patients with Hashimoto′s thyroiditis in different thyroid functional states, which is correlated with inflammatory factors.

OBJECTIVE:
To investigate the value of hand-held retinal optometer and optical coherence tomography (OCT) in predicting postoperative visual acuity in patients with age-related cataract and idiopathic macular epiretinal membrane.
METHODS:
We retrospectively analyzed the data of patients undergoing phacoemulsification combined with intraocular lens implantation for age-related cataract in our hospital from January, 2019 to April, 2020.Preoperative examination detected idiopathic macular epiretinal membrane in 45 of the patients (52 eyes) with lens opacity grade C2N2P1 according to LOCSⅡ lens opacity classification criteria.Based on the thickness of the macular fovea, the eyes were divided into group A (9 eyes) with macular thickness < 300 μm by OCT examination, group B (25 eyes) with macular thickness of 300 to 400 μm, and group C (18 eyes) with macular thickness >400 μm.The best corrected visual acuity and retinal visual acuity before operation and the best corrected visual acuity on the first day and at 3 months after the surgery were compared among the 3 groups.The consistency between the preoperative retinal vision and the best corrected vision at 3 months after the surgery was analyzed.
RESULTS:
The best corrected visual acuity at one day and 3 months after the surgery differed significantly from that before the surgery in all the 3 groups (
CONCLUSIONS
For patients with cataract and idiopathic macular epiretinal membrane, phacoemulsification combined with intraocular lens implantation can improve postoperative vision.Hand-held retinal optometer can accurately assess postoperative vision in patients with stage C2N2P1 cataract.Patients with a macular thickness >400 μm caused by idiopathic macular epiretinal membrane are likely to have poor postoperative visual outcomes.

【Objective】 To evaluate the dietary quality with the dietary balance index (DBI_16) and the association between dietary quality and bone mass among middle-aged and elderly people in Gansu Province so as to provide evidence for improving dietary quality and bone health status of Gansu population. 【Methods】 Based on the information of the type and quantity of food intake and the bone mass of middle-aged and elderly people aged 35 years and above collected by the Gansu Project in the Regional Ethnic Cohort Study in Northwest China, DBI_16 was used to evaluate the intake level of cereals, vegetables, fruits, milk, beans, fish and shrimp, eggs and other foods, and the degree of inadequate, excessive and unbalanced dietary intake of the participants. Multiple linear regression was used to evaluate the associations of three component indexes of DBI_16, high bound score (DBI_HBS), low bound score (DBI_LBS), diet quality distance (DBI_DQD), and seven single indexes of DBI_16 with bone mass. 【Results】 Analyses of the dietary and bone mass data of 11,840 participants showed that 44.8% of participants consumed excessive amounts of cereals compared to the dietary recommendation. 96.3%, 90.6%, 90.1%, 71.9%, 95.1% and 60.3% of participants’ intake of vegetables, fruits, milk, soybeans, fish and shrimp, and eggs, respectively, were inadequate. 47.7% participants consumed less than 10 types of food. 2.3% participants’ DBI_LBS levels were appropriate. 54.7% participants’ DBI_HBS levels were appropriate. Only 1.2% participants’ DBI_DQD reached a balanced level. The bone mass level in the study population was (2.5±0.6) kg [(2.8±0.5) kg for men and (2.3±0.5) kg for women]. After adjusting for sociodemographic characteristics, lifestyle, total dietary energy intake and body mass index, DBI_LBS and DBI_DQD were negatively associated with bone mass [β and 95% CI was -0.002 01 (-0.003 62--0.000 40) and -0.001 76 (-0.003 09--0.000 43), respectively]. 【Conclusion】 Dietary intake imbalance is common among middle-aged and elderly people in Gansu Province, and the more severe the dietary intake imbalance, the lower the bone mass level.
