Objective:To study the efficacy and drug-related adverse reactions of long-term appli-cation of biological anti-rheumatic drugs (bDMARDs) to patients with ankylosing spondylitis (AS), and provide reference for clinical diagnosis and treatment.Methods:We retrospectively analyzed the clinical data of AS patients who were followed-up for more than 5 years in the Department of Rheumatology and Immunology of Peking University Shenzhen Hospital. The patients treated with bDMARDs alone or combined with traditional antirheumatic drugs were included as the treatment group, while those who did not receive biological or non-biological antirheumatic therapy were included as the control group. The data collected included clinical sym-ptoms, inflammatory biomarkers, imaging results, drug applications and drug-related adverse reactions, etc. The counting data were tested by χ2 test, the measurement data in normal distribution was tested by t test, and the measurement data that not normally distributed was tested by Mann-Whitney U test. Paired test was used for statistical processing before and after treatment. Results:We collected the data of 114 eligible patients, including 64 in the treatment group and 50 in the control group. There were no significant differences in baseline data between the 2 groups, including mean follow-up time, course of disease, age, sex ratio, HLA-B27 positive rate, morning stiffness duration, night pain, peripheral arthritis, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and imaging. After 5 years, patients in the treatment group had shorter morning stiffness [(3±7) min vs (26±37) min, t=4.827, P<0.01], lower nighttime pain rates [(3/64, 4.8%) vs (29/50,58.0%), χ2=38.329, P<0.01], lower ESR level [(14±14) mm/1 h vs (20±18) mm/1 h, t=2.102, P=0.038], lower CRP level [(7±8) mg/L vs (14±19) mg/L, t=2.431, P=0.017], and lower progression rate of sacroiliac arthritis [(18/64, 28.1%) vs (35/50, 70.0%), χ2=19.786, P<0.01], than the control group. The main drug-related adverse reactions in the treatment groupincluded reversible leucopenia, elevated transaminase level, redness and swelling at the injection site. Conclusion:Biologics treatment for more than 3 consecutive years can effectively control the clinical symptoms of most AS patients, reduce inflammatory indicators and delay the imaging progression of the sacroiliac joint. Without treatment, the imaging progress of the sacroiliac joint in AS patients could be 70% after 5 years.

BACKGROUNDTo investigate the relationship between the size of primary tumor, pathologic classification, cell differentiation or location of tumor and lymph node metastasis in lung cancer.
METHODSThree hundred and thirty-two patients with lung cancer underwent pulmonectomy plus extensive dissection of hilar and mediastinal nodes. The law of lymph node metastasis was analyzed.
RESULTSA total of 3 280 lymph nodes were removed. Metastatic rates of N1 and N2 were 29.9% and 22.4% respectively. The total lymph node metastatic rates of T1, T2, and T3 diseases were 8.5%, 27.4% and 61.2% respectively ( P < 0.005). No lymphatic metastasis was observed in well-differentiated squamous cell carcinoma, however, the lymph node metastatic rates in moderate- and poor-differentiated squamous cell carcinoma were 16.8% and 19.6% respectively. The lymph node metastatic rates were 27.5% and 71.6% in moderate- and poor-differentiated adenocarcinoma respectively ( P < 0.005). The total lymph node metastatic rates in central and peripheral squamous cell carcinoma were 19.6% and 11.7% respectively ( P < 0.005), while in adenocarcinoma, the rates were 57.9% and 24.0% respectively ( P < 0.005). The N2 metastatic rates in central and peripheral squamous cell carcinoma were 10.9% and 2.9% respectively ( P < 0.005), while in adenocarcinoma, the rates were 47.5% and 17.8% respectively ( P < 0.005 ). Under the same T status, cell differentiation or location of tumor, the metastatic rate of adenocarcinoma was much higher than that of squamous cell carcinoma ( P < 0.005 ).
CONCLUSIONSThe frequency of lymph node metastasis significantly correlate with size of primary tumor, pathological classification, cell differentiation and location of tumor.

Objective To evaluate the efficacy and safety of pelvic arterial embolization (PAE) in women with intractable primary postpartum hemorrhage (PPH). Methods Clinical data of 36 cases were analyzed retrospectively in which women underwent PAE for intractable primary PPH in Peking Union Medical College Hospital between Jan 2006 and Jan 2015. The success rate of PAE were measured and possible predictive risk factors associated with treatment failure were analyzed. The complications secondary to PAE were also recorded. Results (1)The etiology of PPH. Among the 36 cases, 21 patients delivered viginally (Group VD) and 15 received cesarean section (Group CS). The most frequent cause of PPH was uterine atony (72%, 26/36). The less common causes were placental problems (28%, 10/36), genital tract trauma (6%, 2/36) and coagulation defects (3%, 1/36) in turn. Three patients (8%, 3/36) had combined causes.(2)Interventions before PAE. Uterotonic medications were used in all patients. 31 patients received carboprost methylate suppositorites,27 received carbetocin and 31 received carboprost tromethamine. Besides, 20 patients received one or more surgical interventions before PAE. PAE was performed when these interventions failed. (3) Characteristics of PAE. Altogether 78 arteries were embolized in 36 cases. Embolization of bilateral uterine arteries was performed in 31 cases, right internal iliac artery and bilateral inferior epigastric arteries were embolized in one case. Right internal pudendal artery, bilateral uterine arteries and bilateral internal iliac arteries were embolized in one case. And bilateral uterine arteries, bilateral internal iliac arteries were embolized in one case. In the other 2 cases, bilateral internal iliac arteries were embolized.(4)Efficacy of PAE. The overall technical success rate of PAE was 100%(36/36), while the clinical success rate was 94%(34/36). All patients survived.(5)Complications of PAE. 15 patients were transferred to ICU after PAE for 1 to 7 days. Except self-limited fever, no puncture site hematoma, buttock necrosis or vessel rupture was observed. The effect on menstrual cycle and fertility were followed in 25 patients. 17 (68%, 17/25) reported resumption of normal menses and 8 (32%, 8/25) reported amenorrhea. Three pregnancies after PAE were observed. Conclusion PAE is a safe and effective treatment for intractable primary PPH which can prevent hysterectomy and preserve fertility of patients.

Objective:To observe the long-term effects of conventional disease modifying anti-rheumatic drugs (cDMARDs) in the treatment of ankylosing spondylitis (AS) and drug-related adverse reactions, and provide reference to clinical treatment and assessment.Methods:Retrospective analysis was performed for AS patients with more than 10 years follow-up records in the Department of Rheumatology and Immunology, Peking University Shenzhen Hospital. The AS patients enrolled were treated with cDMARDs, non-steroid anti-inflammatory Drugs (NSAIDs), and glucocorticoidsonl only. The treatment group was treated continuously for at least 3 years, and the control group was untreated or treated for less than 3 months. Clinical symptoms, inflammatory indicators, imaging results and drug-related adverse reactions of all patients were collected for statistical analysis. The counting data were tested by χ2 test, the measurement data in normal distribution was tested by t test, and the measurement data that not normally distributed was tested by mann-whitney U test. Paired test was used for statistical processing before and after treatment. Results:A total of 166 eligible patients were included, including 111 in the treatment group and 55 in the control group. There were no statistical significant differences between the treatment group and the control group at baseline including the mean follow-up time, symptomatic disease course, age, sex ratio, human lymphocyte antigen (HLA)-B27 positive rate, duration of morning stiffness, pain at night, peripheral arthritis, ESR, CRP and imaging data. After 10 years, the treat-ment group had shorter morning stiffness[(8±18) vs (22±34), U=2 228, P=0.008], less nocturnal pain [(2/1.9%) vs (19/36.5%), χ2=37.037, P<0.01], lower ESR level [(14±13) vs (20±19), t=2.249, P=0.026], lower CRP level [(6±6) vs (10±11), t=2.154, P=0.033], lower incidence of peripheral arthritis [(23/20.7%) vs(25/45.5%), χ2=10.946, P=0.001] and lower sacroiliac arthritis progression rate [(28/25.2% ) vs (46/83.6%), χ2=50.922, P<0.01], and lower spinal progression rate [(8/7.2%) vs (51/92.7%), χ2=117.407, P<0.01] compared with the control group. The differences between the two groups was statistically significant. The main medications and drug proportions in the treatment group were as follows: sulfasalazine (100%), methotrexate (86.5%), NSAIDs (98.2%), glucocorticoid (78.4%) and thalidomide (62.2%). The main drug-related adverse reactions that occurred during the treatment included dizziness, abnormal menstruation, and reversible liver dysfunction. Conclusion:The combination of cDMARDs can effectively control the clinical symptoms of most AS patients, reduce inflammation indicators, delay the progression of sacroiliac joint and spinal damage, and have no serious drug-related adverse reactions. Almost all of the untreated AS patients have radiographic progression of the sacroiliac joint and spine.

Objective To observe the clinical characteristics of ankylosing spondylitis (AS) patients with hyperuricemia (HUA), and to understand the correlation between AS and HUA, so as to improve the understanding of AS patients with HUA. Methods A retrospective analysis was carried out in patients with the diagnosis with AS from November 2012 to August 2016. Patients were divided into two groups based on complicated with and without HUA. The clinical manifestations, inflammatory indicators, imaging manifest-ations, treatment and outcomes of the two groups were statistically analyzed, and the follow-up results of some patients with HUA were analyzed. The chi-square test was used for the counting data. The measurement data in line with the normal distribution were tested by t test, and the measurement data in non-normal distribution were tested by Mann-Whitney U test. Results Three hundred and sixty-two patients with AS were collected, consisting of 288 males (79.6%) and 74 females (20.4%), aged from 14 to 72 years, a course of disease was 3 months to 40 years. There were 87 cases (24.0%) with hyperuricemia, 77 cases were male (88.5%, 21.3%of all AS patients), and 10 were female (11.5%, 2.8% of all AS patients). Shorter morning stiffness time [(13 ±31) min and (22 ±48) min, Z=-2.231, P=0.026], lower IgM level [(1.4 ±1.3) g/L and (3.0 ±4.3) g/L, Z=-2.040, P=0.041], and lower erythrocyte sedimentation rate [(25±17) mm/1 h and (33±22) mm/1 h, t=-2.617, P=0.007] in the HUA group when compared with patients without HUA. The difference between the two groups was statistically significant. Four cases (4.6%) had gout arthritis in the group with HUA, all were male, blood uric acid level all>420 μmol/L. There were 7 cases (8.0%) of urolithiasis in the group with HUA, and 24 cases (8.7%) of urolithiasis in the group without HUA, but there was no statistically significant difference in the incidence of urolithiasis between the two groups. None developed hypertensive disease, heart disease, nephropathy, or diabetis. Conclusion The incidence of hyperuricemia is high in AS, and with lower disease activity, and fewer complications.

Objective:To explore the characteristics of intestinal flora in female patients with type 2 diabetes mellitus (T2DM) with comorbid coronary heart disease.Methods:Female patients with T2DM from September 2019 to November 2020 were enrolled in this study and divided into 2 groups stratified by coronary heart disease: 22 patients with coronary heart disease(T2DM+ CHD group) and 49 patients with simple T2DM group(T2DM group). Thirty-one healthy females were selected as the normal control group(NC group). The abundance of intestinal flora, the difference in intestinal flora and its relationship with indicators such as glycosylated hemoglobin and fasting blood glucose was analyzed by the real-time fluorescent quantitative PCR detection technology in the three groups.Results:The abundance of Prevotella in the T2DM group was lower, and Roseburia inulinivorans and Faecalibacterium prausnitzii in the T2DM+ CHD group were lower, while Bacteroides and Enterococcus spp in the T2DM+ CHD group were higher compared with NC group, respectively( P<0.05). The abundance of Bacteroides and Enterococcus spp in the T2DM+ CHD group was lower than that in the T2DM group( P<0.05). Spearman correlation analysis showed that the abundance of Faecalibacterium prausnitzii and Eubacterium rectale was negatively correlated with obesity while abundance of Bacteroides and Enterococcus spp was positively correlated with HbA 1C and fasting blood glucose. The abundance of Bacteroides was positively correlated with TCH and TG(all P<0.05). Logistic regression analysis showed that Bacteroides and Enterococcus spp were independent influencing factor of the development of female patients with T2DM and CHD. Conclusion:Female T2DM and T2DM with CHD had intestinal flora imbalance, which was related to a variety of glucose and lipid metabolism indicators, and might be closely related to the occurrence of T2DM and CHD. Bacteroides and Enterococcus spp were independent influencing factors of the development of female patients with T2DM and CHD. Regulating the intestinal flora can provide ideas for the prevention and treatment of T2DM with CHD in female.

Rheumatic diseases, a typical kind of autoimmune disease, are often treated with glucocorticoids, immunosuppressants, biological agents, and small-molecule targeted drugs, which often leads to immune dysfunction in patients and increases the risk of activation of latent tuberculosis infection. To regulate the screening, diagnosis, and prophylactic treatment of latent tuberculosis infection in patients with rheumatic diseases, reduce the risk of developing active tuberculosis and improve the prognosis, Peking University Shenzhen Hospital, Shenzhen Third People′s Hospital and Peking Union Medical College Hospital jointly organized domestic experts in the field of rheumatology and tuberculosis to establish the expert consensus on the diagnosis and treatment of latent tuberculosis infection in patients with rheumatic diseases. This consensus focuses on epidemiology, the importance of screening, screening methods, and prophylactic anti-tuberculosis treatment strategies for latent tuberculosis infection combined with rheumatic diseases.

Objective:To investigate the risk factors of dysplasia in patients with ulcerative colitis (UC) in China.Methods:From March 1st, 2012 to December 30th, 2013, a total of 154 UC patients were prospectively enrolled from the following 11 hospitals, Xijing Hospital of Digestive Diseases, Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Peking Union Medical College Hospital, Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Nanfang Hospital affiliated to Southern Medical University, China-Japan Friendship Hospital, The Second Hospital of Hebei Medical University, West China Hospital affiliated to Sichuan University, The Seventh Medical Center of PLA General Hospital, Zhongshan Hospital affiliated to Xiamen University, and the First Affiliated Hospital of Anhui Medical University. The patients were followed up till December 1st, 2017. All the UC patients underwent colon endoscopy and histopathological evaluation. T test and Chi-square test were used for statistical analysis. Cox proportional risk model was used for identifying the risk factors of dysplasia in UC patients. Results:Finally, 133 UC patients were enrolled, the age was (50.0±11.9) years, the diagnosis age was (35.5±11.6) years, the course of disease was (14.5±6.7) years, and the number of endoscopic examinations was (3.4±1.6) times. A total of 21 patients were detected with dysplasia. No patients were detected with colorectal cancer. The results of univariate analysis revealed that the diagnosis age (hazard ratio ( HR)=1.05, 95% confidence interval ( CI) 1.01 to 1.10, P=0.009) and extensive colitis ( HR=2.92, 95% CI 0.97 to 8.79, P=0.057) were factors with statistically significant difference. The results of multivariate analysis revealed that the old age at diagnosis ( HR=1.06, 95% CI 1.02 to 1.11, P=0.003) and extensive colitis ( HR=3.68, 95% CI 1.21 to 11.19, P=0.022) were independent risk factors of dysplasia in UC patients. The cumulative incidence of dysplasia of UC patients with extensive colitis was higher than that of patients with left-sided colitis (24.3%, 17/70 vs. 6.3%, 4/63), and the difference was statistically significant ( χ2=8.023, P=0.005). Conclusions:Extensive colitis and older age at diagnosis are two independent risk factors of dysplasia in UC patients of our country. The cancer monitoring should be strengthened in UC patients with long course of disease and extensive colitis.
