Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Background: Serum human chorionic gonadotrophin (hCG) is higher in twin than that in singleton pregnancies. As hCG stimulates the thyroid to produce more free thyroxine (FT4), which may lead to decreased thyroid-stimulating hormone (TSH) levels, the reference ranges of thyroid-related indicators may differ between singleton and twin pregnancies in the first trimester. This study aimed to establish reference ranges for thyroid-related indicators in early twin pregnancies and to compare them with singleton pregnancies. Methods: Data of 820 twin-pregnant women were extracted from the established database of all pregnant women who delivered at Peking University First Hospital from October 2013 to May 2018; 160 who met National Academy of Clinical Biochemistry criteria were included to establish TSH and FT4 reference ranges. We screened 480 (3:1 paired) women with singleton pregnancies from the same database as controls. The Mann-Whitney test for TSH and FT4 levels was applied for comparisons between singleton and twin pregnancies. Results: First-trimester reference ranges (4–12 gestational weeks) for twin pregnancies were: TSH 0.69 (0.01–3.35) mIU/L and FT4 16.38 (12.45–23.34) pmol/L. Median TSH was significantly lower at 7 to 12 gestational weeks than that at 4 to 6 gestational weeks (0.62 vs. 0.96 mIU/L, Z = -1.964, P = 0.049); FT4 was not significantly different between the two groups. Compared to singleton pregnancies, median TSH was significantly lower (0.69 vs. 1.27 mIU/L, Z = -6.538, P = 0.000), and FT4 was significantly higher (16.38 vs. 14.85 pmol/L, Z = -7.399, P = 0.000) in twin pregnancies in the first trimester. Conclusions Specific reference ranges for thyroid-related indicators for twin pregnancies are needed to avoid a misdiagnosis of thyroid dysfunction. Moreover, establishment of separate reference ranges for 4 to 6 and 7 to 12 gestational weeks in twin pregnancies may be considered.

Background:Clinical outcomes of undifferentiated arthritis (UA) are diverse,and only 40 ％ of patients with UA develop rheumatoid arthritis (RA) after 3 years.Discovering predictive markers at disease onset for further intervention is critical.Therefore,our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.Methods:We performed a prospective,multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals.Clinical and serological parameters were obtained at recruitment.Follow-up was undertaken in all patients every 12 weeks for 2 years.Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.Results:A total of 234 patients were recruited in this study,and 17 (7.3％) patients failed to follow up during the study.Among the 217 patients who completed the study,83 (38.2％) patients went into remission.UA patients who developed RA had a higher rheumatoid factor (RF)-positivity (42.9％ vs.16.8％,x2=8.228,P=0.008),anti-cyclic citrullinated peptide (CCP) antibodypositivity (66.7％ vs.10.7％,x2 =43.897,P ＜ 0.001),and double-positivity rate of RF and anti-CCP antibody (38.1％ vs.4.1％,x2 =32.131,P ＜ 0.001) than those who did not.Anti-CCP antibody but not RF was an independent predictor for RA development (hazard ratio 18.017,95％ confidence interval:5.803-55.938;P ＜ 0.001).Conclusion:As an independent predictor of RA,anti-CCP antibody should be tested at disease onset in all patients with UA.

Objective To explore the preparation of a rat model of pneumonia model induced by Pseudomonas aeruginosa( PA) using different methods,and to lay the foundation for further studies. Methods 48 SD rats were randomly divided into 4 groups:the control group (A), the intratracheal injection group (B), the trachea cannulation group (C) and the intranasal inoculation group ( D) . After intervention with different treatment modalities, the body weight,tempera-ture,white blood cell count and lung pathological changes in the rats of all groups were detected at 5, 10, 15 days. Results 1. The behavior, body weight, temperature, leukocytes and pathological inflammatory changes of the lung in rats of the model groups were significantly different from that of control group. 2. Pseudomonas aeruginosa was detected in rats of all the model groups, but the control group was negative. Conclusions Rat model of Pseudomonas aeruginosa infected pneu?monia can be successfully established by intranasal inoculation. This method can avoid the inflammatory interference from operation, and is simple and suitable for popularization.

OBJECTIVETo observe the influence of therapy with Chinese medicine Lirukang Granule (, LRKG) combined with psychological intervention on anxiety states and sex hormones in patients with cyclomastopathy and menoxenia.

METHODSA total of 470 subjects were randomly assigned to three groups by the net-central randomization system, the treatment group (161 patients, treated with LRKG and psychological intervention), the Chinese medicine group (157 patients, treated with LRKG), and the psychological intervention group (152 patients, treated with psychological intervention). The dose of LRKG was 12 g three times per day; psychological intervention included establishing relations, cognitive intervention and psychological persuasion, 30-40 min per session, once a week. The therapy duration for all groups was three months. The efficacy was compared and anxiety state/State-Trait Anxiety Invertory (STAI) scoring was measured before and after treatment. The serum estradiol (E2), progesterone (P), prolactin (PRL) and follicle stimulating hormone (FSH) levels of 60 patients selected randomly from each group during the luteal phase were measured before and after treatment, and a group of 20 healthy women were evaluated for comparison. A follow-up was arranged for one year after treatment.

RESULTSThirty subjects were lost to follow-up. (1) Comparison of efficacy: the markedly effective rate and the total effective rate of the treatment group were 86.67% (131/150) and 98.00% (147/150), respectively; of the Chinese medicine group, 64.58% (93/144) and 90.27% (130/144), respectively; and of the psychological intervention group, 0% (0/146) and 3.42% (5/146), respectively. The markedly effective rate and the total effective rate in the treatment group were significantly higher than those in the Chinese medicine and psychological intervention groups (P < 0.05). (2) Comparison of STAI scoring: STAI scoring was decreased dramatically in the treatment group after treatment compared with that of the Chinese medicine group (P < 0.01), but there was no significant difference compared with the psychological intervention group. (3) Comparison of levels of sex hormones: E2, P, PRL and FSH of the three patient groups were disordered before treatment, and significantly different from healthy women (P < 0.01). After treatment, the levels of P and FSH of the treatment group were significantly increased (P < 0.01), E2 and PRL were significantly reduced, which were also significantly decreased compared with the psychological intervention groups (P < 0.01). (4) FOLLOW-UP: the markedly effective rate and the total effective rate of the treatment group remained higher than those of the other two groups after one year of treatment (P < 0.05). (5) Adverse reactions: no obvious adverse reactions were found among the three groups.

CONCLUSIONSTherapy with Chinese medicine combined with psychological intervention was effective for short-term and long-term treatment of cyclomastopathy and menoxenia. The mechanism might be related to the regulation of sex hormones.

BACKGROUNDThyroid peroxidase (TPO) is an important autoantigen in Hashimoto's thyroiditis (HT), and almost all epitopes are located in TPO ectodomain. The glycosylation of TPO might contribute to breaking self-tolerance, therefore, purified glycosylated recombinant TPO ectodomain is prerequisite of elucidating its role in the pathogenesis of HT. The aim of our study was to investigate whether the glycosylation has influence on the antigenic determinants of recombinant TPO.

METHODSBac-to-Bac baculovirus expression system was used to generate recombinant human TPO ectodomain. The antigenicity was analyzed by antigen specific enzyme-linked immunosorbant assays (ELISAs). The glycosylation of recombinant human TPO ectodomain of High Five insect cell origin was detected by lectin-ELISAs.

RESULTSTPO ectodomain was recovered from the culture media as a soluble protein, and it was fused with a hexahistidine tag which allowed purification by nickel-affinity chromatography. The recombinant TPO ectodomain could be recognized by all the 54 HT patients and three TPO monoclonal antibodies. Fucose, sialic acid and galactose were all detected on the recombinant TPO ectodomain. Sera TPOAb binding decreased slightly after non-specific deglycosylation of TPO by periodic acid.

CONCLUSIONSHigh Five insect cells derived recombinant human TPO ectodomain had N-glycosylation sites, which might have little effect on recognition by serum TPOAb.

OBJECTIVETo compare the short-term outcomes of surgical treatment for non-small cell lung cancer (NSCLC) by video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT).

METHODSData of 737 consecutive NSCLC patients who underwent surgical treatment for non-small cell lung cancer by video-assisted thoracoscopic surgery and 630 patients who underwent pulmonary resection via open thoracotomy (as controls) in Cancer Institute & Hospital, Chinese Academy of Medical Sciences between January 2009 and August 2011 were retrospectively reviewed. The risk factors after lobectomy were also analyzed.

RESULTSIn the 506 NSCLC patients who received VATS lobectomy, postoperative complications occurred in 13 patients (2.6%) and one patient died of acute respiratory distress syndrome (0.2%). In the 521 patients who received open thoracotomy (OT) lobectomy, postoperative complications occurred in 21 patients (4.0%) and one patient died of pulmonary infection (0.2%). There was no significant difference in the morbidity rate (P > 0.05) and mortality rate (P > 0.05) between the VATS group and OT group. In the 190 patients who received VATS wedge resections, postoperative complications occurred in 3 patients (1.6%). One hundred and nine patients received OT wedge resections. Postoperative complications occurred in 4 patients (3.7%). There were no significant differences for morbidity rate (P = 0.262) between these two groups, and there was no perioperative death in these two groups. Univariate and multivariate analyses demonstrated that age (OR = 1.047, 95%CI: 1.004 - 1.091), history of smoking (OR = 6.374, 95%CI: 2.588 - 15.695) and operation time (OR = 1.418, 95%CI: 1.075 - 1.871) were independent risk factors of postoperative complications.

CONCLUSIONSTo compare with the NSCLC patients who should undergo lobectomy or wedge resection via open thoracotomy, a similar short-term outcome can be achieved via VATS approach.

OBJECTIVETo explore the appropriate strategies which are suitable for the areas with diverse health and economic resource settings in China by estimating the life outcomes and cost-effectiveness of several cervical cancer screening strategies.

METHODSMarkov model was used to calculate the long-term effectiveness, utility, benefit and cost among screened and unscreened cohorts in rural and urban areas, and then analyses of cost-effectiveness, cost-utility and cost-benefit were performed. The assessed screening strategies were acetic acid of visual inspection combined with Lugol's iodine staining (VIA/VILI), conventional Pap smear and simple HPV DNA testing (careHPV) in rural areas, and conventional Pap smear, simple HPV DNA testing (careHPV), HPV DNA testing (HC2) and liquid-based cytology (LBC) alone or combined with HPV DNA testing (LBC+HC2) in urban areas. We estimated the life outcomes and cost-effectiveness of the above screening strategies at one-year, 3-year and 5-year intervals.

RESULTSAll of the screening strategies were effective to decrease cervical cancer mortality and to increase life years, with a trend of shorter screening interval having better effectiveness. However, no matter in urban or rural areas, compared with careHPV testing at 5-year interval, the costs of other screening strategies were 1.28 - 13.86 folds, 1.31 - 14.14 folds, and 1.27 - 12.80 folds higher to avoid one death, to save a year of life, and a QALY, and the benefit per cost of other screening strategies was 9.9%-90.2%.

CONCLUSIONScareHPV testing at 5-year interval has the best cost-effectiveness performance and the highest benefit-cost ratio with the moderate life outcomes. It is the optimal cervical cancer screening strategy to be generalized in our country. careHPV testing at 3 years interval can be considered in more developed areas to achieve better effectiveness.
