Objectives To study the relationship between TCM syndromes and adiponectin (APN) level, carotid atherosclerosis plaque of hypertension complicated with carotid atherosclerosis, and provide evidence for clinical diagnosis and treatment. Methods One hundred patients of hypertension complicated with carotid atherosclerosis were divided into phlegm syndrome group, stasis syndrome group, and intermingled phlegm and blood stasis syndrome group, and compared with 30 healthy people as control. Carotid atherosclerosis plaque was detected with GE LOGIQ500 color ultrasound system. ELISA was used to determine the serum APN. Results APN of the intermingled phlegm and blood stasis syndrome group was obviously lower than other groups, and there were obvious differences among them. There were more plaques in the intermingled phlegm and blood stasis syndrome group. A negative correlationship was showed between carotid artery intima media thickness (IMT) and APN of hypertension complicated with carotid atherosclerosis. Conclusion There is correlation between TCM syndrome and APN level, carotid atherosclerosis plaque of hypertension complicated with carotid atherosclerosis. The anomalous change of APN and plaque formation of the patients can be preliminarily estimated with the syndrome of TCM.

METHODS: Mucosa absorption experiment and deposit effect were made on a two cells diffusion apparatus in vitro to calculate permeation coefficients. RESULTS: With increasing of the concentration of Cip, the permeation coefficient of mucosa absorption showed a increasing tendency, but deposit effect declined significantly. After using l menthol, the permeation coefficient of Cip showed a declining tendency. Especially at 0.2 percent concentration of l menthol, the decrease level was more obvious than other groups (P

Objective To explore the distinctive ultrasonographic characters of enthesitis in patients with spondyloarthritis (SpA) and evaluate the diagnostic value of ultrasonography in SpA by comparing ultrasonography of enthesis in the lower limbs of patients with SpA,rheumatoid arthritis (RA) and osteoarthritis(OA).Methods Entheses in the lower limbs (quadriceps tendon,proximal patellar ligament,distal patellar ligament,achilles tendon and plantar aponeurosis) were detected in SpA,RA,OA patients and health controls by ultrasonographic examination.Results A total of 46 SpA,23 RA and 12 OA patients were enrolled in this study,with 26 SpA and 7 RA patients complaining of heel pain(P ＜0.05).There were 126 enthesal sites(126/460,27.2％) were detected abnormal in SpA group,compared with 54 of 230 (23.5 ％) sites in RA group and 27 of 120 (22.5 ％) sites in OA group (P ＞ 0.05).Sixty five (70.7 ％) sites of the distal patellar ligaments were abnormal in SpA group,while that were 19(41.3％)in RA group(P ＜ 0.05)and 13 (54.2％)in OA group.Twenty six sites of tendon thickness and 22 sites of bone erosion in the distal patellar ligaments were found in SpA group,while only one site of each in RA group(P ＜ 0.05) and 4 sites of tendon thickness in OA group (P ＜ 0.05) were found.Tendon thickness,bursal synovitis and bone erosion coexisting in one distal patellar ligament indicated SpA,the sensitivity,specificity and the area under the curve (AUC) of which were 70.7％,65.5％ and 0.740,respectively.Conclusion Tendon thickness and bone erosion of entheses were more likely the distinctive ultrasonographic characters of enthesitis in SpA patients.Tendon thickness,bursal synovitis and bone erosion in the distal patellar ligament could be an ideal tool for SpA diagnosis.

Purpose The diagnosis of adult onset Still's disease (AOSD) is usually difficult due to the lack of specific clinical manifestation.This paper summarizes the manifestations of 18F-FDG PET/CT in adult onset Still's disease and investigates the value of PET/CT in diagnosis and differential diagnosis of AOSD.Materials and Methods Fiftyfour patients who was diagnosed as AOSD were selected and underwent 1 8F-fluorodeoxyglueosepositron emission tomography/computed tomography (18F-FDG PET/CT).The clinical features,laboratory examination and the maximum standard uptake value (SUVmax) of liver,spleen,bone marrow,lymph node were collected.Then the main PET/CT manifestations of patients with AOSD,the influence factor of SUVmax and correlation between SUVmax and laboratory indexes were analyzed.Results FDG accumulation occurred mainly in bone marrow (88.89％;SUVmax:3.91 ± 1.16),spleen (79.63％,SUVmax:3.24±0.89) and lymph node (77.78％;SUVmax:3.83± 1.97).FDG accumulation can also occurred in joints,parotid gland,submandibular gland,pleural and other organs.Compared with the nonglucocorticoid group,SUVmax of the spleen,bone marrow and lymph node were significantly decreased in the glucocorticoid group with or without fever (P＜0.05),whereas the SUVmax of liver,spleen,bone marrow and lymph node between the two glucocorticoid groups were not statistically different (P＞0.05).The SUVmax of liver,spleen,bone marrow and lymph node between two groups with or without disease-modifying anti-rheumatic drugs were not statistically different (P＞0.05).Correlation analysis showed that spleen SUVmax and lactate dehydrogenase,bone marrow SUVmax and C reactive protein were weakly correlated (r=0.33 and 0.30,P＜0.05).Conclusion The main manifestations of 18F-FDG PET/CT of AOSD are FDG accumulation in spleen,bone marrow and lymph nodes.Glucocorticoid can reduce the SUVmax.18F-FDG PET/CT can help to rule out malignancy,guide biopsy and assist in definite diagnosis of AOSD.

Objective To study the characteristics of work disability and its influencing factors in patients with ankylosing spondylitis (AS). Methods The demographic data, work conditons and disease related characteristics of 277 patients with AS were recorded, and randomly selected from the Department of Rheumatology, Chinese PLA General Hospital from November 2014 to January 2016. Work and productivity activity impair-ment questionnaire (WPAI) was used to survey the work disability and productivity loss, then explore its in-fluencing factors and the relationships between patient-reported outcomes and WPAI scores. Logistic regression was used to analyze the associated factors of work disability. Multivariate linear regression was used to analyze the predictive factors of lose of work productivity. Results The prevalence of work disability was 30.3%. Twenty patients were unemployed because of working disability. Two hudreds patients were employed, with average 36.5 (24.0, 50.0) hours workingtime in the past week. Average AS related absenteeism was 4.4 (0, 10) hour. Average workproductivity loss was 26.4%(2.5%, 40.0%). Logistic multiple regression analysis showed that Bath AS disease activity index (BASDAI), SF-36 physical component summary (PCS) scores might be the important influencing factors among those clinical measures ( OR=1.270, 0.959). Presenteeism and overall work impairment were moderately correlated with patients' global assessment of disease activity (VAS), BASDAI, bath AS functional index (BASFI), SF-36 physical Functioning (PF), SF-36 body pain (BP) and SF-36 Physical Component Summary (PCS) (|r|=0.539-0.648). Linear multivariate analyses indicated that work presente-eismand absenteeismwere significantly associated with BASDAI (P<0.01). Conclusion High prevalence of work disability in patients with AS is noted, which is closely related with disease activity and body function;High attention should be paid to AS patients with work disability.

Objective To investigate the efficacy of arthroscopic synovectomy on refractory knee arthritis complicated with popliteal cyst.Methods Patients diagnosed as rheumatoid arthritis (RA) or spondyloarthritis (SPA) with refractory knee arthritis who underwent knee arthroscopic synovectomy in our hospital from 2010 to 2017 were enrolled,including 20 patients (16 RA,4 SpA) with popliteal cyst.Clinical data,RA disease activity score (DAS28),SpA back pain score,etc,were collected to evaluate the efficacy of knee surgery.Results Erythrocyte sedimentation rate (ESR) [58(17,79)mm / 1h vs.19(9,30)mm/1h,P＜ 0.001],C reactive protein (CRP) [3.72(0.92,8.14) mg/L vs.0.85(0.10,3.08) mg/L,P＜0.001],rheumatoid factor [64.6(20.2,193.3) vs.20.5(10.0,58.4),P＜0.001],DAS28 score(4.67±1.25 vs.2.81±1.23,P＜0.001),knee joint discomfort score [5(4,6) vs.2(1,3),P＜0.001] and the volume of knee joint effusion by ultrasound (P＜0.05) in 95 RA patients were significantly decreased compared to those before operation.ESR [27(12,54)mm/1h vs.20 (16,28) mm/1 h,P＜0.001],CRP [3.27(1.06,6.95) mg/L vs.1.41(0.34,3.03)mg/L,P＜0.001],knee discomfort score [2(0,5) vs.1(0,3),P＜0.05],back pain visual analogue score (VAS) [5(4,5) vs.2(1,3),P＜0.001],and the volume of knee joint effusion by ultrasound (P＜0.001) in 58 SpA patients were significantly lower than those before the operation.The rate [16.84％(16/95) vs.6.32％(6/95),P=0.023] and grading (P=0.007) of popliteal cyst in RA were decreased after the operation.No statistically difference was observed in the rate [6.90％ (4/58) vs.5.17％(3/58),P=0.697] of popliteal cyst in patients with SpA,yet with a trend of decrease in 4 patients.Conclusion This study provide evidence that knee arthroscopic synovectomy has a good effect for refractory knee arthritis,which can reduce disease activity,improve joint symptoms and decrease the grading of popliteal cyst.

The study aimed to analyze the efficacy and safety of rituximab in the treatment of 23 cases of lupus nephritis and explore the prospect of half-dose rituximab in lupus nephritis treatment. Twenty-three patients with lupus nephritis hospitalized in the Department of Rheumatology and Immunology at the First Medical Center of the PLA General Hospital from May 2013 to December 2021 were selected. Eighteen patients received rituximab 375 mg/m 2 on the first and 14th days, 5 patients received 500 mg of rituximab on the first and 14th days, and rituximab was used as needed 6 months later. Methylprednisolone (80-120 mg) was given together with rituximab. Afterward, 1 mg/kg prednisone was used for 4 weeks, which was progressively tapered to maintenance doses or discontinued. B lymphocyte level, renal function, 24-h urine protein level, and systemic lupus erythematosus (SLE) disease activity index 2000 (SLEDAI2K) score before and after treatment were recorded. The efficacy and adverse reactions were analyzed. The results showed that 11 patients suffered from renal insufficiency [creatinine (162.7±58.6) μmol/L ] at baseline, while the creatinine level of 9 patients returned to normal 12 months after the treatment [ (66.3±10.1)μmol/L ]. Normal renal function of the other 12 patients was maintained during treatment. After 12 months, the 24-h urine protein level decreased from 4.00 (2.00,6.80) g in the baseline period to 0.10 (0.08,0.40) g. SLEDAI2K score decreased from 22 (18,26) in the baseline period to 3 (0,6) 12 months after the treatment. The B lymphocyte level reached 0.00 (0.00,0.01)% at 3 months. Of 23 patients, 13 patients achieved complete remission, and 7 patients achieved partial remission after 6 months of rituximab treatment. Five patients experienced adverse reactions related to rituximab, including 1 case of transfusion reaction, 1 case of perioral herpes with pulmonary infection, and 3 cases of decreased IgG levels. Therefore, rituximab regimen used in this study can be an effective treatment strategy for lupus nephritis.

We retrospectively analyzed therapy efficacy and the adverse reactions of 10 patients suffering from systemic lupus erythematosus (SLE) with intestinal involvement treated with rituximab (RTX). Patients were hospitalized in the Department of Rheumatology and Immunology of the First Medical Center of PLA General Hospital from January 2015 to January 2023. Among the 10 patients, two were men and eight were women. The age of the cohort was (41.9±8.8) years. The age at disease onset was (28.8±9.2) years. The total course of the SLE diagnosis was(109.6±59.9) months. The course of the diagnosis of SLE with intestinal involvement was (89.3±50.2) months. The time from the appearance of intestinal symptoms to the diagnosis of SLE with intestinal involvement was 1.5 (1.0,8.0) months. The time from the diagnosis of SLE with intestinal involvement to RTX use was 13.0 (1.0,46.3) months. Follow-up duration after application of RTX treatment was (55.3±28.4) months. There were five cases of abdominal pain, four cases of abdominal distension, nine cases of diarrhea, three cases of nervous-system involvement, nine cases of lupus nephritis, and seven cases of serositis. All 10 patients underwent computed tomography and radiology of the abdomen. Eight patients had intestinal-wall edema, seven suffered intestinal dilation, four had target signs, three suffered congestion of mesenteric blood vessels, eight had increased mesenteric-fat density, and six had false intestinal obstruction. All 10 patients showed a low level of complement C3 (250-750 mg/L). Nine cases showed a low level of complement C4 (10-90 mg/L). The SLE disease activity index 2000 (SLEDAI-2K) at baseline in 10 patients was 20.5 (17.8, 30.0). After receiving RTX (0.5 g: day 1, day 14, or 375 mg/m 2: day 1, day 14) induction treatment, the intestinal symptoms of 10 cases were relieved completely. Four patients had adverse reactions, of which three received a high-dose glucocorticoid combined with RTX treatment simultaneously. Adverse reactions manifested mainly as a reduced level of IgG and infection with herpes simplex virus in one case, reduced level of IgG and lung infection in one patient, lung infection in one case, and reduced IgG level in one patient. RTX may an efficacious treatment strategy for patients suffering from refractory SLE with intestinal involvement.

Objective: To investigate and analyze the clinical features, epidemiologic information and pathogenic characteristics of a rabies patient. Methods: Clinical data of the patient(boy) was collected and epidemiological survey was conducted, fluorescence quantitative reverse transcription-polymerase chain reaction (FQRT-PCR) and reverse transcription-polymerase chain reaction (RT-PCR) were used to detect the samples of saliva, cerebrospinal fluid (CSF), skin tissue with hair follicle at the back of the neck for rabies laboratory diagnosis. Results: Early symptoms of the boy were vomiting, diarrhea, fever and irritability, followed by coma and death. The boy had nasal trauma one month ago and the domestic dog died of illness during the same period. He did not accept the rabies post-exposure prophylaxis (PEP). The result of the saliva sample was positive by FQRT-PCR. The predicted segments of the glycoprotein(G), nucleoprotein (N) genes of rabies virus were amplified from the positive saliva sample of the patient by RT-PCR. Compared with rabies virus strains in Henan province, the nucleotide homology and amino acid homology in G gene segment were 96.5%-98.8% and 96.5%-99.2% respectively. Conclusions The case was diagnosed in laboratory as rabies case. The pathogenic rabies virus strain was endemic in Henan province. The nasal trauma, the dead domestic dog were probably related to the infection of the boy.
