Rheumatism of TCM(Traditional Chinese Medicine) is a kind of clinical frequent,common-see and refractory disease,which owns complex pathogenesis and pathogenic factors,with marginal and multi-disciplinary manifestations.The inconsistency in synopsis results in some di culties in research and impairs the development of clinical treatment.Therefore,it is a utmost important theme before us that how and by which ways to perform researches,also an important premise for normalization research on this disease.We try to explore the thinking and method of scienti c research of rheumatic disease from both basic and clinical aspects in this paper.

0.05). Low shear stress and high shear stress of BRV in GC control group were (20.32?5.42)mPa?s and(7.96?3.16)mPa?s, respectively;those in GC LMWH group were (11.42?5.03)mPa?s and (3.96?3.07)mPa?s,respectively after operatin. Low shear stress and high shear stress of BRV were (21.82?6.17)mPa?s and ( 8.62 ?3.48) mPa?s,respectively in PC control group;those in PC LMWH group were (13.11?5.17)mPa?s and (4.96?3.61)mPa?s. After operation,there were no hemorrhagic complications in GC and PC LMWH groups. Conclusions Low shear stress and high shear stress of BRV rise generally seeing in GC and PC patients after operation,and in PC patients are higer than those in GC patients. The use of Low molecular weight heparin could reduce the occurrence of thrmbosis.

Objective To investigate clinicopathological features、diagnosis and surgical treatment of duodenal stromal tumors. Methods A retrospective clinical analysis was made in 23 cases of duodenal stromal tumors admitted from 1995 to 2004. Results Melena and abdominal pain was the most common presenting symptom. Complete resection was achieved in all cases, including pancreatoduodenectomy in 13 cases, by pylorus-preserving pancreatoduodenectomy in 3 cases, and tumor enucleation in 7 cases. The mean size of the tumor was 6. 6 cm (2 - 21 cm) , among them 10 cm in 6. Pathologically tumors less than 5 cm were all of potential malignancy, whereas those larger than 5 cm were malignant. Follow-up of 2 months to 9 years found all cases alive and healthy except for one who died of liver metastasis one year postoperatively. Conclusion Duodenal stromal tumors were low malignancy tumors. Aggressive surgery is the choice of treatment. Favorable prognosis is expected after complete surgical excision.

Objective:To describe the population and area distribution differences in the prevalence of urinary incontinence in middle-aged and elderly adults in 10 areas in China.Methods:A total of 24 913 participants aged 45-95 years who completed the third resurvey of China Kadoorie Biobank during 2020-2021 were included. The prevalence of urinary incontinence was assessed by an interviewer-administered questionnaire, and urinary incontinence was classified as only stress urinary incontinence, only urgency urinary incontinence and mixed urinary incontinence. The prevalence of urinary incontinence and its subtypes were reported by sex, age and area, and the severity of urinary incontinence and treatment were described.Results:The average age of the participants was (65.4±9.1) years. According to the seventh national census data in 2020, the age-standardized prevalence rates of urinary incontinence was 25.4% in women and 7.0% in men. The age-standardized prevalence rates of only stress, only urgency and mixed incontinence were 1.7%, 4.2% and 1.2% in men and 13.5%, 5.8% and 6.1% in women, respectively. The prevalence rates of urinary incontinence and all subtypes in men and the prevalence of urinary incontinence and all subtypes except only stress urinary incontinence in women all increased with age ( P<0.001). After adjusting for age, the prevalence of urinary incontinence in both men and women were higher in rural area than in urban area ( P<0.001). The treatment rates in men and women with urinary incontinence were 15.4% and 8.5%, respectively. Conclusions:The prevalence of urinary incontinence was high in middle-aged and elderly adults in China, and the prevalence rate was higher in women than in men, but the treatment rate of urinary incontinence was low.

OBJECTIVETo explore the efficacy and safety of deferasirox in aplastic anemia (AA)patients with iron overload.

METHODSA single arm, multi- center, prospective, open- label study was conducted to evaluate absolute change in serum ferritin (SF)from baseline to 12 months of deferasirox administration, initially at a dose of 20 mg·kg(-1)·d(-1), and the safety in 64 AA patients with iron overload.

RESULTSAll patients started their deferasirox treatment with a daily dose of 20 mg · kg(-1) ·d(-1). The mean actual dose was (18.6±3.60) mg · kg(-1)·d(-1). The median SF decreased from 4 924 (2 718- 6 765)μg/L at baseline (n=64) to 3 036 (1 474- 5 551)μg/L at 12 months (n=23) with the percentage change from baseline as 38%. A median SF decrease of 651 (126-2 125)μg/L was observed at the end of study in 23 patients who completed 12 months' treatment, the median SF level decreased by 1 167(580-4 806)μg/L [5 271(3 420-8 278)μg/L at baseline; 3 036(1 474-5 551)μg/L after 12 months' treatment; the percentage change from baseline as 42% ] after 12 months of deferasirox treatment. The most common adverse events (AEs) were increased serum creatinine levels (40.98%), gastrointestinal discomfort (40.98%), elevated liver transaminase (ALT: 21.31%; AST: 13.11%)and proteinuria (24.59%). The increased serum creatinine levels were reversible and non-progressive. Of 38 patients with concomitant cyclosporine use, 12(31.8%)patients had two consecutive values >ULN, 10(26.3%)patients had two consecutive values >1.33 baseline values, but only 1(2.6%)patient's serum creatinine increased more than 1.33 baseline values and exceeded ULN. For both AST and ALT, no patients experienced two post- baseline values >5 ×ULN or >10 × ULN during the whole study. In AA patients with low baseline PLT count (less than 50 × 10(9)/L), there was no decrease for median PLT level during 12 months' treatment period.

CONCLUSIONSAA patients with iron overload could achieve satisfactory efficacy of iron chelation by deferasirox treatment. The drug was well tolerated with a clinically manageable safety profile and no major adverse events.

OBJECTIVE: To investigate the effects of Naoluo Xintong Decoction (NLXTD) on pyroptosis and angiogenesis of brain microvascular endothelial cells (BMECs) and explore the possible mechanisms in rats with oxygen-glucose deprivation/ reperfusion (OGD/R). METHODS: Rat BMECs with or without caspase-1 siRNA transfection were cultured in the presence of 10% medicated serum from NLXTD-treated rats (or blank serum) and exposed to OGD/R. CCK-8 assay, Transwell chamber assay, and tube formation assay were used to assess proliferation, migration, and tube-forming abilities of the cells. The activity of lactate dehydrogenase (LDH) in the culture supernatant was determined using a commercial assay kit, and the levels of inflammatory factors IL-1β and IL-18 were detected with ELISA. The cellular expressions of pro-caspase-1, caspase-1, NLRP3, Gasdermin D, and angiogenesis-related proteins VEGF and VEGFR2 were detected using Western blotting. RESULTS: The BMECs showed obvious injuries after OGD/R exposure. Compared with the blank serum, the medicated serum significantly improved the cell viability, migration ability, and lumen-forming ability (P < 0.01) and lowered the levels of IL-1β and IL-18 and the LDH release (P < 0.01) of the cells with OGD/R exposure. Western blotting showed that in the BMECs exposed to OGD/R, the medicated serum strongly upregulated the expression of VEGF and VEGFR2 proteins (P < 0.01) and reduced the protein expressions of pro-caspase-1, caspase-1, NLRP3, and Gasdermin D (P < 0.01), and transfection of the cells with caspase-1 siRNA further promoted the expressions of VEGFR2 protein in the cells (P < 0.01). CONCLUSION NLXTD can improve the proliferation, migration, and tube- forming ability and promote angiogenesis of BMECs with OGD/R injury probably by inhibiting the caspase-1/Gasdermin D pathway in pyroptosis, alleviating cell injury, and upregulating the expressions of VEGF and VEGFR2.
