Objective: To investigate the effect of diabetes on the intensity of sarcoplasmic reticulum Ca2+-ATPase (SERCA2a)-SUMOylation and SERCA2a activity of myocardium in experimental rats.
Methods: The 8 weeks old SD rats were divided into 2 groups, Diabetic group, with diet-induced type 2 diabetic rats and Control group, with normal rats. The systolic and diastolic cardiac functions were evaluated by echocardiography and left ventricular pressure measurement. The intensity of SERCA2a-SUMOylation was examined by co-immunoprecipitation and SUMOylation kit.
Results: Compared with Control group, Diabetic group had decreased systolic and diastolic cardiac functions, especially for diastolic function;decreased SERCA2a protein expression and intensity of SUMOylation;decreased SUMOylation E2 (Ubc9 ) protein expression. The protein levels of SUMO1, SAE1 and SAE2 were similar between 2 groups.
Conclusion: The intensity of SERCA2a-SUMOylation and Ubc9 decreased in diabetic myocardium which implies that SERCA2a-SUMOylation and Ubc9 were closely related to the damage of diabetic myocardium in experimental rats.

Objective:To investigate the predictive value of the changes of platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) in the therapeutic efficacy of the neoadjuvant treatment for breast cancer.Methods:The clinical data of 72 breast cancer patients who received neoadjuvant therapy in Nantong Tumor Hospital between February 2020 and January 2022 were retrospectively analyzed and the changes of PLR and NLR before and after neoadjuvant therapy were also analyzed. The receiver operating characteristic (ROC) curves were used to assess the predictive value of PLR, NLR and their changes in pathological complete remission (pCR) after neoadjuvant therapy.Results:The area under the ROC curve of PLR and NLR before the treatment, the difference in PLR before and after the treatment (ΔPLR), the difference in NLR before and after the treatment (ΔNLR) in predicting pCR was 0.520, 0.505,0.724 and 0.686,and the corresponding cut-off value was 269.231, 2.559, -2.840 and -1.457; the patients were divided into high and low groups according to the cut-off values. NLR before the treatment was not correlated with clinicopathological characteristics (all P > 0.05),while PLR before the treatment was correlated with tumor size ( P = 0.029), and ΔPLR was correlated with progesterone receptor expression ( P = 0.025), human epidermal growth factor receptor 2 (HER2) expression ( P < 0.001), molecular subtype ( P < 0.001), N stage ( P = 0.002), clinical stage ( P = 0.002) and treatment modality ( P < 0.001). ΔNLR was associated with HER2 expression ( P = 0.002), molecular subtype ( P = 0.024), tumor size ( P = 0.007), neural invasion ( P = 0.006), N stage ( P = 0.006), clinical stage ( P = 0.016) and treatment modality ( P = 0.014). ΔPLR and ΔNLR were influencing factors for patients achieving pCR after neoadjuvant therapy (all P < 0.05). Conclusions:Stage Ⅲ invasive breast cancer patients with higher ΔPLR and ΔNLR after neoadjuvant therapy have better prognosis.

OBJECTIVETo investigate the relationship between two polymorphisms immediately upstream of the cyclooxygenase 2 (COX2) gene and preeclampsia in a South West Han Chinese population.

METHODSBlood samples from 205 patients with preeclampsia and 276 normal pregnant women as controls from Han Chinese in Chengdu area were analyzed by polymerase chain reaction-restriction fragment length polymorphisms.

RESULTSG and A allele frequencies for -1195G>A site were 48.54% and 51.46% in the patient group, respectively, and 40.40% and 59.60% in the control group, respectively. G and C allele frequencies for -765G>C site were 94.15% and 5.85% in the case group, respectively, and 94.38% and 5.62% in the control group, respectively. The AA genotype and variant A allelic frequencies of the -1195G>A SNP were significantly lower in patients with preeclampsia than in the control group (P<0.05), and the odds ratio for the risk of preeclampsia was 0.665 (95% CI: 0.444-0.982) in women homozygous for the variant COX2 A allele ( x²=4.233, P=0.047). The genotype and allele frequencies of the -765G>C polymorphism in patients with preeclampsia and controls showed no significant differences (P>0.05). Additional subgroup analyses (mild vs severe preeclampsia) of the two polymorphisms failed to reveal significant correlation for either genotypic or allelic frequencies. Furthermore, there was no significant association between the polymorphisms and blood pressure levels in the patient or control groups.

CONCLUSIONCOX2 -1195A homozygosity is associated with a decreased risk for preeclampsia in a South West Han Chinese population. On the other hand, the -765G>C polymorphism has no effect.

Objective To investigate the prevalence of iron deficiency(ID)and iron deficiency anemia (IDA) in pregnant women in urban areas of China. Methods The study was a national cross-sectional survey conducted from September 19th, 2016 to November 20th, 2016. According to the classification of the National Bureau of Statistics, all survey sites were set up in 6 regions of the country. Pregnant women were continuously selected using multistage stratified sampling. A total of 12 403 pregnant women were collected and examined for serum ferritin and hemoglobin levels. Results The median serum ferritin level during pregnancy was 20.60 μg/L(11.78-36.98 μg/L), the hemoglobin level was(118±12)g/L. With the progress of pregnancy, the levels of serum ferritin and hemoglobin decreased gradually. The median serum ferritin levels in the first, second trimester and third trimester were 54.30 μg/L(34.48-94.01 μg/L), 28.60 μg/L(16.40-50.52 μg/L), and 16.70 μg/L(10.20-27.00 μg/L)respectively(P<0.01). The mean hemoglobin levels were(127 ± 10)g/L,(119 ± 11)g/L and(117 ± 11)g/L respectively(P<0.01). The prevalence of ID in urban pregnant women was 48.16%(5 973/12 403), and IDA prevalence was 13.87% (1 720/12 403). The prevalence of IDA in the first, second trimester and third trimester were 1.96% (20/1 019), 8.40%(293/3 487)and 17.82%(1 407/7 897), respectively(P<0.01). The prevalence of standardized ID and IDA were significantly different in various regions of China(P<0.01). The standardized prevalence of ID were relatively higher in East China and Northeast China, 57.37% and 53.41% respectively, while it was the lowest in Southwest China, 30.51%. The standardized prevalence of IDA in South Central, Northwest, and East China were relatively high, 21.30%, 16.97% and 17.53% respectively, and the standardized prevalence of IDA in Southwest China was the lowest, 5.44%,the differents in various regions were significant(all P<0.01). Conclusion The current phenomenon of ID and IDA in pregnant women is still very common,and nutrition and health care during pregnancy should be strengthened.
