Objective To investigate the effect of Gekko on experimental autoimmune myositis(EAM)animal model.Methods From Nov.2003 to May.2004,in the first hospital of Ji Lin university,Guinea pigs were immunized with rabbit muscle homogenate in Freund's adjuvant and a generalized myositis fundamentally similar to humanpolymyositis was established.These animals were divided at random into A,B,C,D groups.A group were treated with small dose Gekko [1 250 mg/(kg?d)],B group were treated with large dose Gekko [3 750 mg/(kg?d)],C group were treated with preinisone [3 mg/(kg?d)],D group received no treatment.Sign,serum muscle enzyme,electromyography(EMG)and muscle biopsy changes were compared.Results A,B,C groups became better.D group showed no significant change.Conclusion Gekko is effective in therapy of EAM guinea pigs.The result of this study provides an evidence that Gekko mightbe used for the treatment of PM.

Objective To determine the genotypes and distribution of MSP2 of Plasmodium falciparum isolates in Yunnan and Hainan provinces, China.Methods The central polymorphic region of MSP2 allele was amplified by the nested PCR for genotyping of P.falciparum. Results The higher degree of polymorphism of MSP2 of P.falciparum was observed in Yunnan and Hainan. Distribution and allele frequencies differed in both provinces, indicating considerable geographical heterogeneity of parasite populations. The mixed infection of different allele type and multiplicity of infection was more frequent in Hainan than in Yunnan.Conclusion There were obvious differences in the distribution and frequencies of MSP2 alleles between Yunnan and Hainan endemic areas. MSP2 is suitable to be used as a marker gene for the genotyping of P.falciparum infection.

Objective:To study the effects of parathyroid hormone (PTH) on BMP3 expression of cultured human dental papilla mesenchymal cells (DPMCs). Methods:DPMCs were obtained by cell culture, BMP3 mRNA expression was studied by in situ hybridization. BMP3 gene expression of human DPMCs after exposure to 33.3 nmol/L PTH for 5 days were measured. The cells cultured in the medium without PTH served as control.Results: Stronger BMP3 positive signals were observed in PTH treated cells than that in the control cells.Conclusion:PTH stimulats BMP3 systhesis of cultured DPMCs.

Objective To investigate the therapeutic effect of Jianpi Yiqi, Bushen Fenjing combined with oxaliplatin+CF/5-FU on colorectal cancer.MethodsEighty patients with colorectal cancer who were treated in our hospital from January 2014 to December 2015 were randomly divided into observation group(40cases) and control group (40cases).The control group was given oxaliplatin+CF/5-FU treatment, the observation group in the control group based on the application of Spleen Qi, Bushen fill essence treatment, observed before and after treatment of two groups of serum tumor markers, clinical symptoms and living conditions, changes, record adverse reactions.ResultsThe observation effect of 82.50% was significantly higher than that of the control group (62.50%).The QOL score (37.8±5.6) was significantly higher than that of the control group (33.5±3.1) and the adverse reaction rate was 30.00% (P<0.05).The difference between the two groups was significant (P<0.05).ConclusionThe effect of invigorating spleen qi and tonifying siren solution combined with oxaliplatin+CF/5-FU on colorectal cancer can improve the clinical symptoms and improve the quality of life of patients.

Objective To investigate the maternal and fetal outcomes of pregnant women with subclinical hypothyroidism, and clinical observation of thyroxine replacement. Methods From March 2014 to March 2015, the clinical records of 216 women with subclinical hypothyroidism(including 166 cases with thyroxine replacement), and hypothyroidism(n=69)during pregnancy who delivered at our hospital were reviewed. The maternal complications and neonatal outcomes were compared with 406 healthy women who delivered during the same period. Results The age, number of fetus, and morbidity rate of gestational hypertension were without significant differences in those groups. The morbidity of gestational diabetes in subclinical hypothyroidism group and hypothyroidism group were significantly higher than those in control group(13.4%, 17.4% vs 0.2%, P<0.05). The rate of thyroid peroxidase antibody and thyroglobulin antibody positive in subclinical hypothyroidism group and hypothyroidism group were significantly higher than those in control group(26.9%, 23.2% vs 9.9%; 15.7%, 23.2% vs 8.1%, all P<0.05). No matter treated or not treated in subclinical hypothyroidism group, the preterm birth, Apgar score, low birth weight, birth defects, and infant congenital hypothyroidism were without significant differences as compared to the control group(P>0.05). Further compared those between treated and untreated subclinical hypothyroidism, the results were also without significant difference(P>0.05). Conclusions Subclinical hypothyroidism had no significant influence on pregnancy outcomes and perinatal events. Thyroxine replacement in subclinical hypothyroidism pregnant women also had no significant influence on pregnancy outcomes and perinatal events.

Objective:To clarify the effect of the reform of Sichuan medical association on the coordinated development of medical re-sources supply and regional economy,and provide a basis for continuing to promote the coordinated development.Methods:Based on the panel data of 18 prefecture-level cities and 3 autonomous prefectures in Sichuan Province from 2009 to 2021,the medical resources invest-ment and economic development level of each city(state)in Sichuan Province were calculated by entropy weight method.Through the cou-pled coordination model,the degree of coordinated development was measured.The discontinuous time series model is used to measure the impact of the implementation of the medical association policy on the degree of coordinated development.Results:From 2009 to 2021,the supply of medical resources in Sichuan Province showed an overall upward trend,but the characteristics of the first concentration were ob-vious.In 2021,the coupling degree between medical resources investment and economic development in Sichuan Province is high(0.808),but the coupling coordination degree was still in a barely coordinated stage(0.540).The implementation of the reform of medical associa-tion effectively promoted the coordinated development of medical resource supply and regional economy.Conclusion:Local governments need to further strengthen the building of medical associations.By making long-term medical resources planning and exploring the role of digital technology in the medical field,it will further promote the expansion and balanced distribution of high-quality medical resources.

Purpose: To assess the feasibility of applying ultra-widefield fundus (UWF) images for macular staphyloma area (MSA) measurement and investigate the associated factors with MSA. Methods: This is a retrospective study. MSA was measured by UWF imaging. Central foveal thickness, subfoveal choroidal thickness, subfoveal scleral thickness were measured on spectral domain optical coherence tomography. Intraclass correlation coefficients of MSA measurement would be evaluated. Multiple linear regression analysis was used to analyze the associated factors with MSA. Results: In total, 135 eyes of 92 patients were enrolled. The mean age was 64.73 ± 10.84 years. Mean MSA on UWF image was 279.67 ± 71.70 mm2. Intraclass correlation coefficients of MSA measurement was 0.965 (95% confidence interval [CI], 0.946 to 0.977; p < 0.001). In the multiple linear regression analysis, after adjusting for subfoveal choroidal thickness, best-corrected visual acuity, central foveal thickness, and subfoveal scleral thickness, the factors independently related to MSA were axial length (β = 8.352; 95% CI, 3.306 to 13.398; p = 0.001), sex (β = -26.673; 95% CI, -51.759 to -1.586; p = 0.037), age (β = 1.184; 95% CI, 0.020 to 2.348; p = 0.046). Conclusions It is feasible to measure MSA on UWF image. Female, longer axial length, and older age may indicate larger MSA.
