Observational Study
Long-term physical health consequences of abortion in Taiwan, 2000 to 2013: A nationwide retrospective cohort study.
The aim of this study was to quantitatively estimate the long-term risk of abortion-related consequences and comorbidities. We identified 36,375 patients with at least 2 diagnosed abortions from 2000 to 2013 and included them in the abortion group. This group was further subdivided into 4 subgroups: spontaneous abortion, induced abortion, nonspecific abortion, and mixed-type abortion groups. ⋯ The induced abortion group showed a statistically significant elevated adjusted HR of 1.291 for urinary tract infection (P = .008) but statistically insignificant HRs of 1.031 for pelvic inflammatory disease, 1.637 for ectopic pregnancy, 5.114 for placenta previa, 65.434 for placenta abruption, 0.998 for incompetent cervix, 0.285 for early onset of labor, and 1.019 for subsequent infertility with no subsequent conception. Clinicians encountering patients in a predicament such as spontaneous or induced abortion should unprejudicely and objectively inform the patients of the effects or influence of abortion on their physical health, including statistically significant and insignificant risks. Induced abortion may not be an independent risk factor for subsequent infertility.

Observational Study
Anemia is inversely associated with serum C-peptide concentrations in individuals with type 2 diabetes.
The purpose of the study was to test the hypothesis that anemia is related with serum C-peptide concentrations in individuals with type 2 diabetes mellitus (DM). This cross-sectional study was carried out in 1300 individuals with type 2 DM. We measured fasting C-peptide, 2-hour postprandial C-peptide, and postprandial C-peptide minus fasting C-peptide (ΔC-peptide) concentrations. ⋯ According to the grade of anemia, the average C-peptide concentrations differed significantly after adjusting for other covariates. In the multivariable model, the statistically significant relation between anemia and serum C-peptide concentrations remained after adjusting for confounders, including age, gender, family history of diabetes, body mass index, duration of diabetes, glycated Hb, free fatty acids, hypertension, and hyperlipidemia (fasting C-peptide concentration: β = -0.057, P = .032; postprandial C-peptide concentration: β = -0.098, P < .001; ΔC-peptide concentration: β = -0.095, P < .001). Anemia was inversely associated with serum C-peptide concentrations in individuals with type 2 DM.

Observational Study
Association study of gut flora in Wilson's disease through high-throughput sequencing.
In this study, we analyzed the difference of intestinal flora polymorphisms between Wilson's disease (WD) patients and healthy people by high-throughput sequencing technology, and explored the correlation between WD and intestinal flora polymorphism. A total of 22 cases of WD patients and 22 healthy persons as control were recruited. The total DNA was extracted from the fecal specimens of all the subjects, V4 high variable region of 16S rRNA gene was amplified and sequenced by high-throughput sequencing. ⋯ Compared with the control group at the level of the genus, the abundance of Bacteroides (4.85% vs 4.6%, P < .05), Faecalibacterium (2.92% vs 2.13%, P < .05), Megamonas (0.84% vs 0.22%, P < .001), Lachnospira (0.16% vs 0.09%, P < .001) significantly increased in WD group, while the abundance of Prevotella (1.63% vs 2.48%, P < .001), Roseburia (0.75% vs 1.39%, P < .001) and Phascolarctobacterium (1.72% vs 2.45%, P < .001) significantly decreased in WD group. PCoA and UPGMA tree analysis showed that there were significant differences of gut microbial compositions between the 2 groups. The diversity and composition of intestinal flora in the WD patients were significantly lower than those in the healthy controls, and the diversity of intestinal flora may be associated with the presence of WD.

This retrospective study aimed to investigate the effect and safety of Yiqibushenhuoxue decoction (YQBSHXD) for the treatment of chronic obstructive pulmonary disease (COPD). This study involved 120 cases of patients with COPD. These cases were assigned to an intervention group and a control group equally, 60 subjects each group. ⋯ However, YQBSHXD may help to alleviate the severity of dyspnea on exertion, as measured by 6MWD (P = .03), and to improve the quality of life, as assessed by the SGRQ (P < .01). Additionally, no significant differences in AEs were detected between the 2 groups. The results of this study showed that YQBSHXD may help to manage COPD after 12-week treatment, although the lung function has not been improved.

The aim of this study was to describe the size and the shape of gravida-0 uteri in infertile Chinese Han women according to age, height, and body mass index (BMI). Registered data obtained from the Department of Reproductive Medicine, Xiangya Hospital of Central South University, were collected and analyzed. The length, width, and anteroposterior diameter of the uteri of nonpregnant women aged 20 to 45 years were measured by transvaginal ultrasonography. ⋯ The correlations between uterine length, width, anteroposterior diameter, and height were also considered statistically significant (all P < .001), while there was no correlation between L/W ratio and height. The results showed that uterine size and BMI had no statistical significance. The uterine length, width, and anteroposterior diameter gradually increased with increased age and height, but the increasing extents was different, and the uterine shape became rounder with age and had not changed with height in primary infertile women.
