[Effect of Different Fertilization Treatments on Methane and Nitrous Oxide Emissions from Rice-Vegetable Rotation in a Tropical Region, China].

The study of the effects of different fertilization treatments on soil methane (CH) and nitrous oxide (NO) emissions in rice-vegetable rotation systems is of great significance to supplement the research gap on greenhouse gas emissions in tropical regions of China. In this study, four fertilization treatments were set up during the pepper season:phosphorus and potassium fertilizer application (PK); nitrogen, phosphorus, and potassium (NPK) application; half application of nitrogen, phosphorus, and potassium plus half application of organic fertilizer (NPK+M); and application of organic fertilizer (M). There was no fertilizer application during the following early rice season.

[Effects of Water and Fertilization Management on CH and NO Emissions in Double-rice Paddy Fields in Tropical Regions].

Paddy soils are widely considered a main source of methane (CH) and nitrous oxide (NO). Comprehensively evaluating CH and NO emissions from double-rice systems in tropical regions with different water irrigation and fertilizer applications is of great significance for addressing greenhouse gas emissions from such systems in China. In this study, eight treatments were evaluated:conventional irrigation-PK fertilizer (D-PK), conventional irrigation-NPK fertilizer (D-NPK), conventional irrigation-NPK+organic fertilizer (D-NPK+M), conventional irrigation-organic fertilizer (D-M), continuous flooding-PK fertilizer (F-PK), continuous flooding-NPK fertilizer (F-NPK), continuous flooding-NPK+organic fertilizer (F-NPK+M), and continuous flooding-organic fertilizer (F-M).

Ultrasound analysis of the effect of second delivery on pelvic floor function in Chinese women.

In our study, patients who had a second delivery were categorised into the following 4 groups. Pelvic floor ultrasound data were compared during the 6th week after the second delivery. The incidence of cystoceles was highest in group A and lowest in group D.

Thyroid structure, function and iodine status by pregnancy trimester in Harbin, China.

Background And Objectives: Thyroid disease in pregnancy can have devastating effect on the fetus. In Harbin, China, there is insufficient knowledge about the incidence of and contributing factors to thyroid disease in pregnancy. This study investigates whether urine iodine concentration (UIC), as a proxy for iodine intake, affects the thyroid structure and/or function during each trimester.

Urine iodine level and multiple risks are associated with thyroid structural abnormalities among adults in Heilongjiang Province, China.

Background And Objectives: The prevalence of adult thyroid structural abnormalities has increased significantly worldwide. However, no study has examined the thyroid structure and urine iodine levels of adults in Heilongjiang Province in the last decade. Therefore, this study aims to investigate the rate and risk factors of thyroid structural abnormalities among the residents of this province.

Contrast-Enhanced Ultrasonography in Sclerotherapy for Ovarian Endometrial Cyst.

We investigated contrast-enhanced ultrasonography (CEUS) characteristics related to the perfusion pattern and parameters of the time-intensity curve of ovarian endometrial cysts (OECs) pre- and post-sclerotherapy. Forty-three patients with one-sided, single, untreated OECs underwent CEUS pre- and post-sclerotherapy. OEC wall thickness was measured by 2-D ultrasonography and CEUS, and CEUS enhancement patterns and time-intensity curve parameters before and after sclerotherapy were compared.

Four-dimensional hysterosalpingo-contrast sonography with auxiliary hydrogen peroxide examination for the diagnosis of fallopian tube patency following interventional treatment of ovarian ectopic cysts.

Objective: The present study aimed to explore the practical value of using four-dimensional hysterosalpingo-contrast sonography with auxiliary hydrogen peroxide examination which is necessary for the diagnosis of fallopian tube patency following treatment of ovarian ectopic cysts.

Methods: A retrospective analysis of hysterosalpingography (HSG) examination data from 71 patients who had received sonography-guided interventional treatment for ovarian ectopic cysts at the Fourth Affiliated Hospital of Harbin Medical University was carried out. The 71 cases were divided into three groups.

Contrast-Enhanced Sonographic Features Before and After Interventional Treatment of Ovarian Endometrial Cysts.

Objectives: The purpose of this study was to assess contrast-enhanced sonography features before and after interventional treatment of ovarian endometrial cysts.

Methods: We retrospectively analyzed 53 patients with ovarian endometrial cysts who underwent contrast-enhanced sonography before and after interventional treatment to assess the sonographic features of the cysts at these different times. The sonographic features and quantitative parameters for the cysts were compared before and after treatment.

Association of IL-1α rs17561 and IL-1 RN rs315952 polymorphisms with Tourette syndrome: a family-based study.

Aim: Immune system dysregulation has been implicated to play a key role in pathogenesis of Tourette syndrome (TS). IL-1α and IL-1RN are important inflammatory cytokines that mediate the inflammation. In this study, we investigated the relationship between single-nucleotide polymorphisms (SNPs) of IL-1α and IL-1RN and the susceptibility to TS in Chinese Han population.

Differentially expressed gene profiles in the serum before and after the ultrasound-guided ethanol sclerotherapy in patients with ovarian endometriomas.

Objectives: To detect the differentially expressed genes and subsequently identify disease-related signatures and potential biomarkers for patients with ovarian endometriomas in the serum before and after the ultrasound-guided ethanol sclerotherapy in patients with ovarian endometriomas.

Design And Methods: Venous blood samples were collected from nine patients with ovarian endometriomas before and after ultrasound-guided ethanol sclerotherapy, and the serum were isolated after centrifugation. NimbleGen human gene expression microarrays analysis was conducted to analyse gene ontology categories (GO terms) and signalling pathways of differentially expressed genes.

rs2043211 polymorphism in CARD8 is not associated with Tourette syndrome in a family-based association study in the Chinese Han population.

Background: Previous studies showed that postinfectious autoimmunity and immune deficiency played an important role in the pathogenesis of Tourette syndrome. CARD8 can suppress activity of NF-ΚB activated by inflammatory mediators.

Objective: To study the association between the rs2043211 polymorphism in CARD8 and susceptibility to Tourette syndrome in Chinese Han population.

Correlation between ovarian chocolate cyst and serum carbohydrate antigen 125 level and the effect of ultrasound-guided interventional sclerotherapy on serum carbohydrate antigen 125 level.

Aim: This study was to investigate the correlation between ovarian chocolate cysts and serum carbohydrate antigen (CA)-125 levels and to demonstrate the effect of ultrasound-guided interventional sclerotherapy (UGIS) on serum CA-125 levels.

Methods: Based on the serum CA-125 level, as determined by chemiluminescence detection prior to UGIS, 105 patients with ovarian chocolate cysts were divided into the normal group (CA-125 ≤ 35 U/mL, 45 patients) and the abnormal group (35 U/mL < CA-125 ≤ 200 U/mL, 60 patients). There were six clinical indicators including age, disease duration, dysmenorrhea history, child-bearing history, abortion history and surgical history.

Clinical effectiveness of multiple-drug injection treatment in unruptured ectopic pregnancies: a retrospective study.

Objectives: To study the effect of local interventional treatment of unruptured ectopic pregnancies with multiple-drug injection guided by color Doppler sonography.

Methods: In this retrospective analysis, 49 patients with an unruptured ectopic pregnancy were treated with two different local injection methods administered under sonographic guidance. The patients were divided into single-drug (n = 23) and multiple-drug (n = 26) injection groups, and they received a locally administered injection of methotrexate alone or a combination including methotrexate, hemocoagulase, antibiotics, and anti-inflammatory drugs, respectively.
