Ankylosing spondylitis is a chronic immunoinflammatory disease that mainly affects the spine and the sacroiliac joint， the mechanism of which is closely related to signaling pathways， such as osteoprotegerin （OPG）/receptor activator of nuclear factor-κB （RANK）/RANK ligand， mitogen-activated protein kinase （MAPK）， Wnt/β-catenin （β-catenin）， phosphoinositide 3- kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）. Traditional Chinese medicine has the characteristics of multiple components and targets， and is widely used for the treatment of autoimmune diseases due to its low toxicity， strong specificity， and high efficacy. This review found that monomers and compounds of traditional Chinese medicine can exert anti ankylosing spondylitis effects by intervening in the aforementioned signaling pathways， regulating immune inflammatory responses， and inhibiting biological processes such as bone destruction， ectopic osteogenic differentiation， cell apoptosis， and autophagy.

OBJECTIVE: To compare the performance of serum cancer antigen 125 (CA125), human epididymis protein 4 (HE4), Risk of Ovarian Malignancy Algorithm (ROMA) and Copenhagen index (CPH-I) for differential diagnosis of benign and malignant diseases in patients with ovarian mass. METHODS: We retrospectively analyzed the data of 719 women with pelvic mass, and the performance of preoperative serum levels of CA125 and HE4, ROMA and CPH-I for differential diagnosis of the masses was compared. RESULTS: Of the 710 women analyzed, 531 were diagnosed with benign ovarian lesions, 44 with borderline ovarian tumors (BOTs), 119 with epithelial ovarian cancers (EOCs), and 25 with non-EOCs. In differentiating ovarian cancer (OC) and BOT from benign lesions, the area under the receiver-operator characteristic (ROC) curve (AUC) was 0.854 for HE4, 0.856 for ROMA, 0.854 for CPH-I, and 0.792 for CA125, demonstrating better diagnostic performance of HE4, ROMA, and CPH-I than CA125 alone; the diagnostic sensitivity was 56.9% for HE4, 70.2% for CA125, 69.1% for ROMA, and 63.8% for CPH-I; the specificity was the best with HE4 (94.4%) and CPH-I (94.7%). In sub-analysis of EOC benign lesions, the AUCs of HE4, ROMA, and CPH-I increased to 0.946, 0.947, and 0.943, respectively, all greater than that of CA125 (0.888). In other sub-analyses, HE4, ROMA, and CPH-I all showed greater AUCs than CA125 alone. CONCLUSIONS This study confirms the accuracy of HE4, ROMA, and CPH-I for differentiating malignant from benign ovarian mass, and all these 3 tests show better performance than CA125. Furthermore, HE4 and CPH-I is superior to ROMA and CA125 in terms of specificity, while CA125 and ROMA have better diagnostic sensitivities.

Objective:To evaluate the application of PG-SGA,NRS 2002 and BIA in nutritional assessment and screening of patients with gynecologic cancers.Methods:118 patients were randomly selected.Nutritional status were evaluated by PG-SGA,NRS 2002 and BIA,and consistency between each tools were compared.Results:The prevalence of malnutrition or nutritional risk of patients were 64.4％ (PG-SGA),57.6％ (NRS 2002),and 33.9％ (BIA) respectively.In all patients,the consistency of PG-SGA and NRS 2002 was high (P ＜ 0.001),while there were not significantly consistent between BIA and PG-SGA,or between BIA and NRS 2002 (P ＜ 0.001).Conclusion:According to the evaluation of PG-SGA or NRS 2002 in gynecologic patients,the prevalence of malnutrition or nutritional risk is high,and these two scales are suitable for nutritional assessment and screening of gynecologic cancer patients,especially in ovarian cancer patients.In addition,BIA may be a promising tool to evaluate cervical cancer patients' nutritional status.

Objective The paper is an attentative effort to evaluate the reaction and mechanism of estrogen on pregnant rabbits with acute lung injury caused by hemorrhagic shock. Methods Sixty pregnant New Zealand white rabbits were randomly divided into 6 groups, with 10 rabbits in each group, namely normal control group (NG group, with anesthesia only), estrogen group (E2G group, with additional estrogen injection at 60 min) and the other four hemorrhagic shock groups underwent hemorrhagic shock (i.e. E2SG, FSG, SBSG, E2SBSG group;mean blood pressure-40 mmHg(1 mmHg=0.133 kPa)by phlebotomy for 15 min. After maintenance of the pressure for 45 min, the rabbits were treated with E2(0.37 mg/kg), fructose injection(5%,2 ml/kg), the p38 mitogen-activated protein kinases(p38MAPK) inhibitor SB-203580 (2 mg/kg) or E2 plus SB-203580. Tumor necrosis factor alpha(TNF-α), interleukin-6(IL-6) were measured at different time points(0 min, 60 min, 80 min and 260 min), lung tissue methane dicarboxylic aldehyde(MDA) level, lung tissue myeloperoxidase(MOP), superoxide dismutase(SOD) activity, lung tissue dry weight/wet weight (DW/WW) value were measured after the experiment was finished, pulmonary pathology of the rabbits was observed. Result (1) Serum TNF-α level of NG group and E2SG group were not significantly different compared with the other four groups at the 0 min and 60 min. At 80 min and 260 min of experiment, serum TNF-αlevel of all the four shock groups were increased, E2SG group [(172.4±16.0) and (216.7±18.6) ng/L], FSG group [(171.6 ± 9.1) and (263.9 ± 7.8) ng/L], SBSG group [(172.8 ± 7.2) and (300.6 ± 4.8) ng/L], E2SBSG group [(167.9±4.8 )and (261.8±9.6) ng/L], and significantly higher than NG group and E2G group, separately (P<0.05). (2) Serum IL-6 level of NG group and E2SG group were not significantly different compared with the other four groups at the 0 min, 60 min and 80 min. At 260 min, the serum IL-6 level[(98.3 ± 0.9) and (110.4 ± 1.8) ng/L;(120.9 ± 2.3)and (109.8 ± 2.6) ng/L] of the four shock groups (E2SG, FSG, SBSG, E2SBSG group) were significantly higher than NG group and E2G group (P<0.05). (3) Lung tissue MDA level [(2.20± 0.12),(2.57±0.11),(3.17±0.08), (2.75±1.09) nmol/mg] and MPO activity [(4.45±0.25),(6.65±0.56),(9.55±0.30), (6.78 ± 0.11) U/mg] of the four shock groups (E2SG, FSG, SBSG, E2SBSG group) were higher than NG group and E2G group (P<0.05). (4) Lung tissue SOD activity [(51.8 ± 1.8),(40.2 ± 1.5), (30.0 ± 1.7),(41.2 ± 2.0) U/mg] was significantly higher in the four shock groups(E2SG, FSG, SBSG, E2SBSG group) compared with NG group and E2G group (P<0.05). (5) Lung tissue DW/WW value(0.143 ± 0.008, 0.127 ± 0.008, 0.109 ± 0.006, 0.125 ± 0.008) was significantly lower in the four shock groups(E2SG, FSG, SBSG, E2SBSG group) compared with NG group and E2G group (P<0.05). (6) Lung tissue of the rabbits in NG group and E2G group is basically normal without obvious pathology changes. Lung tissue pathological damage of rabbits was observed in the four shock groups, and the pathological damage of rabbits in SBSG group was most serious. Conclusion Estrogen can reduce acute lung injury of pregnant rabbits with hemorrhagic shock, the p38MAPK pathway plays a critical role in mediating the salutary effects of E2 on shock-induced acute lung injury.

OBJECTIVETo evaluate the effects of estrogen on renal function of pregnant rabbits with hemorrhagic shock.

METHODSForty pregnant New Zealand white rabbits were randomized into 4 groups, namely normal control group (NG group, with anesthesia only), estrogen group (E2 group, with additional estrogen injection at 60 min), estrogen-hemorrhagic shock (E2SG) group and fructose-hemorrhagic shock (FSG) group. In the latter two groups, the rabbits were subjected to phlebotomy for 15 min to induce hemorrhagic shock with a blood pressure of 40 mmHg; after maintenance of the pressure for 45 min, intravenous injections of estrogen or fructose were given before resuscitation 20 min later. Blood urea nitrogen (BUN) and creatinine (Cr) concentration were measured at different time points and renal pathology of the rabbits was observed.

RESULTSNo significant differences were founding serum BUN and Cr levels between NG and E2G groups during the experiment. In FSG and E2SG groups, serum BUN level began to increase at 80 min after hemorrhagic shock and was significantly higher in FSG group (P<0.05); serum Cr level increased progressively from the start of the experiment and began to decrease at 60 min, with a faster rate of reduction in E2SG group (P<0.05).

CONCLUSIONEstrogen can effectively lower serum BUN and Cr levels and ameliorate renal pathologies to offer protective effect in pregnant rabbits against hemorrhagic shock.

OBJECTIVETo evaluate the significance of the serum cystatin C (Cys-C) in assessing renal dysfunction in preeclamptic women.

METHODSNinety-six women with normal pregnancies and 48 with severe preeclampsia were examined for 24-hour creatinine clearance (CrCl), serum creatinine (Scr), Cys-C, uric acid (UA) and beta microglobulin (MG) concentrations during the second and third trimesters and postpartum in severe preeclamptic patients. These indexes were analyzed to estimate the glomerular filtration rate.

RESULTSThe concentrations of Scr, UA and MG were significantly higher in the third trimester than in the second trimester in women with normal pregnancies, where serum Cys-C levels showed no significant variations. Severe preeclamptic patients exhibited significantly higher serum Cys-C levels in the third than in the second trimester. Correlation analyses demonstrated significant negative correlations between Cys-C and 24-hour CrCl in the second and third trimesters in all the 144 pregnant women and in the postpartum period in severe preeclamptic patients.

CONCLUSIONSerum Cys-C can serve as a good indicator for assessing renal function in severe preeclamptic women from antepartum to postpartum periods.
