Objective To investigate the expression of thiredoxin domain containing 5 (TXNDC5) in the synovial tissues and blood samples of various arthritic conditions and autoimmune diseases to further confirm the previous findings, investigate the relations between the expression level of TXNDC5 and clinical parameters of RA. Methods The expression of TXNDC5 in the synovium was quantitatively analyzed by immunohistochemistry, real-time quantitative PCR and Western blotting. The levels of TXNDC5 in blood and synovial fluid was determined using sandwich ELISA in patients with RA, osteoarthritis (OA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS) and normal controls. One-way ANOVA, LSD test and Spearmen' s correlation were used for statistical analysis. Results Immunohistochemistry indicated that TXNDC5 expression was significantly higher in the synovial tissues of RA (100%, 40±9) than in those of OA and AS(200%,4±4). Real time PCR and western blotting confirmed the above findings (P<0.01). Sandwich-ELISA indicated significantly elevated level of TXNDC5 in the blood and synovial fluid of patients with RA (A=1.31±0.37), but not in those of OA, SLE, and AS, the healthy controls (P<0.01). The level of TXNDC5 in the blood of RA patients (A=0.8185±0.299) was positively correlated with the level of anti-CCP (r=0.350, P =0.027). Conclusion The results suggest that the pronounced increase of TXNDC5 expression may stimulate synovial pannus formation in the hypoxic environment of RA.

ObjectiveTo observe effects of ginkgo bilobate extract injection on the hemorheology,blood lipid and c-reactive protein in serum of patients with cerebral infarction. Methods62 cases patients with cerebral infarction were randomly divided into two groups by means of random number table. Two groups were both given routine treatment. The control group was treated with 20ml compound salvia injection, which was added to 250 ml normal saline, once a day, continuous therapy for 14 days, and the treatment group was treated with 20ml ginkgo bilobate extract injection, which was added to 250 ml normal saline, once a day, continuous therapy for 14 days. The clinical symptoms were observed, hemorheology related index, level of blood lipid and c-reactive protein were detected before and after the treatment. ResultsCompared with the control group,hemorheology related index decreased significantly in the treatment group, especially whole blood viscosity ( 1.57±0.28) mpa ·s (P＜0.01). Blood reduced viscosity (13.95 ± 2.07) mpa ·s, erythrocyte aggregation index (1.37±0.12) , hematocrit (42.36±8.16) were also decreased significantly (P＜0.05) .Triglyceride (TG)(1.23±0.12) mmol/L、 cholesterol (TC) (4.29±1.17) mmtmol/L、 low density lipoprotein cholesterol (LDIL-C)(2.31± 0.39) mmol/L and c-reactive protein ( 10.48 ±- 3.82) mg/L in serum in the treatment group were lower than those of the control group (P＜0.01 orP＜0.05) , high density lipoprotein cholesterol (HDL-C) ( 1.78±0.76) mmol/L in serum was higher than that of the control group (P＜0.01) .The total effective rate of the treatment group and the control group was 87.1％ and 67.7％ respectively, there was a significant difference (x2=3.553, P＜0.05). Conclusion The ginkgo bilobate extract injection can protect cerebral infarction from injury,which may be related with its action on regulating the blood viscosity and level of blood lipid.

Objective To observe the histopathologic and ultrastructural characteristics of cornea and adjacent conjunctiva in Mooren’s ulcer. Methods The samples of limbal and central cornea and adjacent bulbar conjunctiva taken from active Mooren’s ulcer after lamellar keratoplasty were cut into paraffin sections and ultrathin sections and observed by light and transmission electron microscopy. The samples taken from patients of a Terrien’s marginal degeneration and a bacterial corneal ulcer were used as controls. Results Chronic inflammation including lymphocytes and plasma cells infiltrating existed in bulbar conjunctiva and sclera of Mooren’s ulcer. Limbal corneal epithelium, Bowman’s membrane, anterior stroma and adjacent superficial sclera melted and the inferior stromal collagen disorganized. The epithelial basement membrane of ulcer progressive edge had been destroyed while the epithelium and stroma kept quiescent. Lymphocytes infiltrated in conjunctiva and corneal epithelium of Terrien’s marginal degeneration with normal epithelial basement membrane, while Bowman’s membrane was destroyed. The epithelial basement membrane of bacterial corneal ulcer was intact. Conclusion Bulbar conjunctiva may act as a local lymph node of Mooren’s ulcer. Epithelial basement membrane of Mooren’s ulcer may have some abnormality as it was invaded first during ulcer progressing and it’s valuable to have a further study.

Objective: To understand the attitudes and perceptions of traditional Chinese medicine (TCM) practitioners in Beijing TCM hospitals regarding the use of Ephedra sinica Stapf (E. sinica, Ma Huang). Methods: A two-stage cross-sectional study was conducted using a questionnaire survey of TCM practitioners in Beijing TCM hospitals between April 2023 and March 2024. The questionnaire included demographic information, the clinical background of TCM practitioners, and the clinical application of E. sinica. Logistic regression analysis was used to analyze the relevant influencing factors when using E. sinica. Results: Of the 465 questionnaires collected, 441 were valid. Among these, 84.81% (374/441) reported having used E. sinica in clinical practice at least once. The commonly used doses of E. sinica—excluding the pediatric department—were 10 g for high doses, 6 g for medium, and 3 g for low. The three most frequently used formulas for E. sinica included Maxing Shigan decoction, Mahuang decoction, and Xiao Qing Long decoction. The most common TCM patterns treated with a high dose of E. sinica were wind-cold exterior pattern, wind-cold invading the lung, and wind and water combat with meridians congealed by cold. The top three Western medical diagnoses when using E. sinica for treatment were common cold, pneumonia, and upper respiratory tract infections. Nearly half of the respondents reported experiencing adverse reactions from the oral administration of E. sinica, with the most common being palpitations, insomnia, and restlessness. Starting with a low dose and gradually increasing it as appropriate was identified as an effective approach. Conclusion This study investigated the attitudes and perceptions of TCM practitioners in Beijing TCM hospitals regarding the dose–efficacy–adverse reaction relationship of E. sinica, providing a reference for the safe and effective clinical use of E. sinica.

Objective To analyze the clinical speciality of invasive fungal infection(IFI)and provide doctors with clinical evidence for early anti-fungal therapy.Method One hundred and thirty-seven patients with 91 male and 46 female,who suffered from invasive fungal infection in ICU from January.1,2000 to June 30, 2006,were enrolled in this study.The age ranged from 17 to 82 years old.Out of 137 patients with IFI,the percentage of albicans candida,glabirate candida,tropicalis candida and parapsilosis candida were 47.4%, 26.3%,20.4% and 3.6%,reseparately.The sputum,urine,blood and other drainages were collected to perform the fungal examination after three days of admission every three days.Results Of 137 patients,42 of them were complicated with hemorrhage,53 patients with IFI developed candida anthema in the chest,abdomen and extremity.,49 patients suffering from IFI had organ dysfunction.The chest image revealed that infiltration caused by IFI especially occurred in apex of lung in some patients.The pathogen analysis displayed that albicans candidiasis easily developed candida anthema,glabirate candidiasis frequently resulted in organ dysfunction,and tropicalis candida led to hemorrhage in some organs.Conclusions The clinical specialty,of IFI caused by candida included hemorrhage,candida anthema,organ dysfunction,and infiltration in apex of lung.
