ABSTRACT
Objective: To evaluate the predictive value of PARIS bleeding score on in-hospital bleeding of acute myocardial infarction (AMI) patients after drug-eluting stent (DES) implantation with dual-antiplatelet therapy (DAPT). Methods: There were 27 594 AMI patients enrolled in China acute myocardial infarction (CAMI) registry between 2013-01-01 to 2014-09-30 from 107 hospitals, and 14 625 of them had successful in-hospital DES implantation with DAPT were studied. Based on BARC (bleeding academic research consortium definition) criteria, the end point major bleeding (MB) events were defined by both BARC type 3, 5 and BARC type 2, 3, 5; the incidence of in-hospital bleeding, clinical features and predictive value of PARIS bleeding score according to different BARC type were evaluated. Results: Compared with non-MB patients, MB patients had the higher PARIS bleeding score, P<0.001. Based on PARIS score risk stratification, taking BARC type 3, 5 as endpoint, 77/14 625 (0.53%) patients had bleeding events, PARIS scores were different among high risk, mid risk and low risk patients, P<0.001; bleeding risk in mid risk patients was 2.38 times higher than low risk patients, P=0.006 and bleeding risk in high risk patients was 4.78 times higher than low risk patients, P<0.001.Taking BARC type 2,3,5 as endpoint,223(1.52%)patients had bleeding events,bleeding risk in mid risk patients was 1.64 times higher than low risk patients, P=0.002 and bleeding risk in high risk patients was 2.23 times higher than low risk patients, P=0.001. ROC analysis showed that PARIS score had predictive value on both BARC type 3, 5 and BARC type 2, 3, 5 bleeding, area under curve (AUC) of BARC type 3, 5 (AUC: 0.672) was higher than AUC of BARC type 2, 3, 5 (AUC:0.596) (z=2.079, P=0.038), which implied that PARIS score had better predictive value in severe bleeding events. Conclusion: PARIS bleeding score had predictive value on in-hospital bleeding in AMI patients after DES implantation with DAPT, it can also be used in bleeding risk stratification. PARIS bleeding score had better predictive value on severe bleeding.
ABSTRACT
<p><b>Background</b>The effect of maternal weights on the risk of iron deficiency anemia (IDA) during pregnancy remains unclear. The study aimed to investigate the association between maternal weight indicators and IDA during pregnancy.</p><p><b>Methods</b>We conducted a cohort study to examine the association between maternal weight indicators, including prepregnancy body mass index and the rate of gestational weight gain (GWG), and the risk of IDA among Chinese pregnant women. Data about new-onset IDA at different trimesters from a national cross-sectional survey were collected; information regarding baseline variables and rate of GWG from women participating in the survey were retrospectively collected. Tested IDA and reported IDA were documented. Multilevel logistic regression to examine the association between maternal weight indicators and the risk of IDA after adjusting for potential confounders was conducted.</p><p><b>Results</b>This study enrolled 11,782 pregnant women from 24 hospitals from September 19, 2016, to November 20, 2016. Among those, 1515 (12.9%) IDA events were diagnosed through test (test IDA); 3915 (33.3%) were identified through test and patient reporting (composite IDA). After adjusting for confounders and cluster effect of hospitals, underweight pregnant women, compared with normal women, were associated with higher risk of test IDA (adjusted odds ratio [aOR]: 1.35, 95% confidence interval [CI]: 1.17-1.57 and composite IDA (aOR: 1.35, 95% CI: 1.21-1.51); on the contrary, overweight and obese women had lower risk of test IDA (aOR: 0.68, 95% CI: 0.54-0.86 overweight; aOR: 0.30, 95% CI: 0.13-0.69 obese) and composite IDA (aOR: 0.77, 95% CI: 0.67-0.90 overweight; aOR: 0.34, 95% CI: 0.21-0.55 obese). The higher rate of GWG was associated with higher risk of IDA (test aOR: 1.86 95% CI: 1.26-2.76; composite aOR: 1.54, 95% CI: 1.16-2.03).</p><p><b>Conclusions</b>Pregnant women who are underweight before pregnancy and who have faster GWG are more likely to develop IDA. Enforced weight control during pregnancy and use of iron supplements, particularly among underweight women, may be warranted.</p>

ABSTRACT
<p><b>OBJECTIVE</b>To investigate surgical method and clinical curative effects of medial patellofemoral ligament (MPFL) reconstruction with great adductor muscular tendon in treating teenagers' recurrent patellar dislocation.</p><p><b>METHODS</b>From May 2012 to September 2014, 19 patients with recurrent dislocation of patellar, including 6 males and 13 females with an average of 16 years old (ranged from 13 to 17 years), the courses of disease ranged from 3 to 18 months(averaged 6 months). All patients were underwent great adductor muscular tendon transposition to reconstruct medial patellofemoral ligament. The curative effects were evaluated by preoperative and postoperative with Lysholm scores and Patellofemoral angle and Q angle.</p><p><b>RESULTS</b>All patients were followed up from 12 to 18 months with an average of 16.5 months. Primary healing was achieved at stage I. No pain, swelling and patellar dislocation or subluxation occurred.

<p><b>AIM</b>To study the relativity of the renocortical lipid peroxidation with renal tubules structure damage in renal injury induced by cisplatin in rats.</p><p><b>METHODS</b>Female Wistar rats were randomly divided into NS group, CDDP(I) group, CDDP(II) group and CDDP(III) group. All rats were injected via the tail vein with NS or cisplatin and NS qd in five days. The changes in content of Scr, BUN and MDA, the activity of SOD and GSH-Px of the renal cortex were measured. Alkaline phosphatase of renal tubular epithelia was stained by histochemistry and the slices of renal cortex were observed.</p><p><b>RESULTS</b>The contents of Scr and BUN of CDDP groups were significantly higher than those of NS group (P < 0.01). The content of renocortical MDA was significantly higher than that of NS group (P < 0.05). The activities of renoconical SOD and GSH-Px were lower than those of NS group (P < 0.05). The content of MDA, activities of renocortical SOD and GSH-Px with the content of Scr and BUN were significantly correlative. Alkaline phosphatase of renal tubular epithelia cells was losed largely and renal tubular epithelia cells were denaturative and necrotic partly in sections.</p><p><b>CONCLUSION</b>The damage of renal cortex was correlative with its lipid peroxidation.

<p><b>OBJECTIVE</b>To describe the costs of medical care and utilization of health service of patients with HIV/AIDS.</p><p><b>METHODS</b>Patients with human immunodeficiency virus (HIV)/AIDS treated in the Beijing You'an Hospital were interviewed retrospectively during December 1999. Data on demographic characteristics, disease process, and utilization of health service and costs of hospital-based medical care were collected.</p><p><b>RESULTS</b>A total number of 29 patients with HIV/AIDS were interviewed, including 17 (58.62%) asymptomatic HIV infections and 12 AIDS patients. Asymptomatic HIV infections had a mean of 6 outpatient visits, 1.3 hospitalizations and 58.6 inpatient hospital days per person-year. AIDS patients made, on average, 7.8 outpatient visits, 2.1 hospitalizations and 200.2 inpatient hospital days per person-year. The outpatient and inpatient medical costs were 13,729 RMB and 4,745 RMB for asymptomatic HIV infections, and 15,053 RMB and 22,242 RMB for AIDS patients per person-year respectively. For those who took both outpatient and inpatient medical care, the medical care costs, including costs of outpatient care and those of inpatient care, were 16,248 RMB for asymptomatic HIV infections and 36,795 RMB for AIDS patients.</p><p><b>CONCLUSION</b>Demands for health services and costs for medical care were high among patients with HIV/AIDS. Further study on utilization of health services and cost of medical care for patient with HIV/AIDS in a wider geographic coverage are needed.</p>
