To explore the correlation of mid-term oral glucose tolerance test (OGTT) and maternal weight gain with adverse pregnancy outcomes in women with gestational diabetes mellitus (GDM). A total of 2611 pregnant women with GDM who were examined and delivered in Women's Hospital, Zhejiang University School of Medicine from July 1st 2017 to 30th June 2018 were enrolled in this study. According to the number of abnormal items of mid-term OGTT results or maternal gestational weight gain (GWG), patients were classified. The incidence of adverse perinatal outcomes in each group and its relation with OGTT results and GWG were analyzed. The incidence of gestational hypertension, premature delivery, macrosomia and large for gestational age infant (LGA) in three abnormal items GDM patients were significantly higher than those in one or two abnormal items GDM patients (all <0.017). The incidence of gestational hypertension and premature delivery in two abnormal items GDM patients were higher than those in one abnormal item GDM patients (all <0.017). The incidence of gestational hypertension and macrosomia in excessive GWG patients were significantly higher than those in inadequate and appropriate GWG patients (all <0.017), and the incidence of LGA were higher than that in inadequate GWG patients (all <0.017). The incidence of premature delivery and low birth weight infants in appropriate GWG patients were significantly lower than those in inadequate and excessive GWG patients, and the incidence of small for gestational age infant (SGA) were significantly lower than that in inadequate GWG patients (all <0.017). In one abnormal item GDM patients, inadequate GWG was a risk factor for premature delivery and SGA (=1.66, 95%: 1.10-2.52; =2.20, 95%: 1.07-4.53), and protective factor for LGA (=0.40, 95%: 0.27-0.59). And excessive GWG was a risk factor for gestational hypertension, premature delivery and low birth weight infants (=2.15, 95%: 1.35-3.41; =1.80, 95%: 1.20-2.72; =2.18, 95%: 1.10-4.30).In two abnormal items GDM patients, inadequate GWG was a protective factor for macrosomia and LGA (=0.24, 95%: 0.09-0.67; =0.54, 95%: 0.34-0.86), while excessive GWG was risk factor for premature delivery (=1.98, 95%: 1.23-3.18).In three abnormal items GDM patients, there was no significant relationship between GWG and adverse pregnancy outcomes. For GDM women with one or two items of elevated blood glucose in OGTT, reasonable weight management during pregnancy can reduce the occurrence of adverse pregnancy outcomes. For those with three items of elevated blood glucose in OGTT, more strict blood glucose monitoring and active intervention measures should be taken in addition to weight management during pregnancy.

BACKGROUND: The aim of this study was to identify the painkillers preferred for self-administration by doctors working at general hospitals in the capital of the Republic of Korea.METHODS: We collected data, using a questionnaire, from 224 doctors working at secondary or tertiary hospitals in the capital of the Republic of Korea from July 1, 2017 to August 31, 2017. The questionnaire included questions on the preferred type of painkiller for each type of pain and the frequency of painkiller intake. Further, we evaluated the participants on the Likert scale to analyze the consideration and cognition of self-administration of painkillers.RESULTS: The doctors in this study tended to state the trade name of the painkillers rather than the generic name. They preferred acetaminophen for headache and nonsteroidal anti-inflammatory drugs for gastrointestinal (GI) pain, dysmenorrhea, toothache, and musculoskeletal pain. In the choice of painkiller for self-administration, they set utmost importance on the effectiveness of the medicine, followed by the potential side effects, physician's prescription, and the pharmacy's recommendation, in that order. The side effects attribute GI complications, hepatotoxicity, drug tolerance, and delayed diagnosis to painkiller use. There were some remarkable differences between surgeons and non-surgeons, men and women, and specialists and trainees in the conception of painkillers and pain control.CONCLUSION: This is the first study worldwide on the trait of the self-administration of painkillers by doctors, which can serve as a useful reference in clinical settings.

PURPOSE: To examine effects of a postnatal care program on self-efficacy, self-management, and glycemic control in women with gestational diabetes mellitus (GDM). METHODS: A non-equivalent control group non-synchronized quasi-experimental design was used. Sixty-two women with GDM were enrolled and assigned to either an experimental group (n=30) or a control group (n=32). The experimental group received an intervention which was postnatal care program for women with GDM. The postnatal care program for GDM included an individual education with leaflet and mobile web-based video with three times of telephone counseling. Effects of the intervention were measured with self-efficacy, self-management questionnaire, and a 75 g oral glucose tolerance test (75g OGTT). Statistical significance was examined using independent t-test and χ2-test. RESULTS: Although there was no significant difference in 75g OGTT (χ2=.11, p=.748) or self-management (t=−1.28, p=.206), there was a statistically significant increase in self-efficacy (t=−2.02, p=.048) in the experimental group compared to that in the control group. CONCLUSION: A postnatal care program is needed for women with GDM to improve their self-efficacy. Further studies are warranted to improve self-management and glycemic control through tailored education for GDM postpartum women.

Objective: Due to the special anatomical structure and pathophysiological mechanism of the central nervous system (CNS), there is a big difference between the repair of brain injury and other systems of the body. More and more evidence shows that targetedly reducing the autoimmune response of brain tissue without affecting the immune function in other parts of the body will be the best optimized treatment for brain injury. Data Sources: This review was based on data in articles published in PubMed up to June 5, 2017, with the following keywords: "immune tolerance", "traumatic brain injury", and "central nervous system". Study Selection: Original articles and critical reviews on immune tolerance and brain damage were selected for this review. References of the retrieved articles were also screened to search for potentially relevant papers. Results: The CNS is isolated from the immune system through the blood-brain barrier. After brain injury, brain antigens are released into the systemic circulation to induce damaging immune responses. Immune tolerance can effectively reduce the brain edema and neurological inflammatory response after brain injury, which is beneficial to the recovery of neurological function. The clinical application prospect and theoretical research value of the treatment of immune tolerance on traumatic brain injury (TBI) is worth attention. Conclusions The establishment of immune tolerance mechanism has a high clinical value in the treatment of TBI. It opens up new opportunities for the treatment of brain damage.

The lymphatic vasculature has been regarded as a passive conduit for interstitial fluid and responsible for the absorption of macromolecules such as proteins or lipids and transport of nutrients from food. However, emerging data show that the lymphatic vasculature system plays an important role in immune modulation. One of its major roles is to coordinate antigen transport and immune-cell trafficking from peripheral tissues to secondary lymphoid organs, lymph nodes. This perspective was recently updated with the notion that the interaction between lymphatic endothelial cells and leukocytes controls the immune-cell migration and immune responses by regulating lymphatic flow and various secreted molecules such as chemokines and cytokines. In this review, we introduce the lymphatic vasculature networks and genetic transgenic models for research on the lymphatic vasculature system. Next, we discuss the contribution of lymphatic endothelial cells to the control of immune-cell trafficking and to maintenance of peripheral tolerance. Finally, the physiological roles and features of the lymphatic vasculature system are further discussed regarding inflammation-induced lymphangiogenesis in a pathological condition, especially in mucosal tissues such as the gastrointestinal tract and respiratory tract.

The immune system is continuously exposed to great amounts of different antigens from both food and intestinal microbes. Immune tolerance to these antigens is very important for intestinal and systemic immune homeostasis. Oral tolerance is a specific type of peripheral tolerance induced by exposure to antigen via the oral route. Investigations on the role of intestinal immune system in preventing hypersensitivity reactions to innocuous dietary and microbial antigens have been intensively performed during the last 2 decades. In this review article, we discuss how food allergens are recognized by the intestinal immune system and draw attention to the role of regulatory T (Treg) and B (Breg) cells in the establishment of oral tolerance and tolerogenic features of intestinal dendritic cells. We also emphasize the potential role of tonsils in oral tolerance induction because of their anatomical location, cellular composition, and possible usage to develop novel ways of specific immunotherapy for the treatment of allergic diseases.

Developments in our comprehension of the autoimmune and inflammation mechanisms in rheumatoid arthritis (RA) have produced targeted therapies that block aberrant immune cells and cytokine networks, and improved treatment of RA patients considerably. Nevertheless, limitations of these treatments include incomplete treatment response, adverse effects requiring drug withdrawal, and refractory cases. Hence, many researchers have redirected efforts towards investigation of other biological aspects of RA, including the mechanisms driving joint tissue repair and balanced immune regulation. This investigation focuses on mesenchymal stem cell (MSC) research, with the ultimate goal of developing interventions for immune modulation and repair of damaged joints. MSCs are multipotent cells capable of differentiating into mesodermal lineage cells. These cells have also attracted interest for their anti-inflammatory and immunomodulatory capacities. They have many distinctive immunological properties, inhibiting the proliferation and production of cytokines by T, B, natural killer, and dendritic cells. Indeed, MSCs have the capacity to regulate immunity-induced peripheral tolerance, suggesting they can be used as therapeutic tools in RA. This review discusses properties of MSCs, in vitro studies, animal studies, and clinical trials involving MSCs. Our review discusses the current knowledge of the mechanisms of MSC-mediated immunosuppression and potential therapeutic uses of MSCs in RA.

OBJECTIVETo observe the effects of moxibustion and treadmill exercise on transcutaneous oxygen tension and exercise capacity in lower limbs of peripheral arterial disease (PAD).

METHODSTotally 58 mild-to-moderate PAD patients were assigned to the control group (18 cases), the moxibustion group (20 cases), and the treadmill exercise group (20 cases) by random digit table. Patients in the control group received conventional drug therapy for 12 weeks. Patients in the moxibustion group and the treadmill exercise group additionally received moxibustion [at Zusanli (ST36), Sanyinjiao (SP6), Yongquan (KI1)] and treadmill exercise respectively, once per day, 5 times per week for 12 weeks in total. Ankle-Brachial Index (ABI) , transcutaneous oxygen tension (TcPO₂), 6-min walking test (6MWT), and walking impairment questionnaire (WIQ) were assessed before and after treatment.

RESULTSCompared with the control group and the same group before treatment, there was no statistical difference in ABI in the moxibustion group and the treadmill exercise group (P > 0.05). But TcPO₂, 6MWT, and WIQ were obviously elevated (P < 0.01). Besides, 6MWT and WIQ assessment of the treadmill exercise group were better than that of the moxibustion group (P < 0.01) after intervention.

CONCLUSIONMoxibustion and treadmill exercise could improve the exercise capacity and TcPO₂of lower limbers in PAD patients.

CD4⁺ regulatory T cells (Tregs) are essential for normal immune surveillance, and their dysfunction can lead to the development of autoimmune diseases, such as type-1 diabetes (T1D). T1D is a T cell-mediated autoimmune disease characterized by islet β cell destruction, hypoinsulinemia, and severely altered glucose homeostasis. Tregs play a critical role in the development of T1D and participate in peripheral tolerance. Pluripotent stem cells (PSCs) can be utilized to obtain a renewable source of healthy Tregs to treat T1D as they have the ability to produce almost all cell types in the body, including Tregs. However, the right conditions for the development of antigen (Ag)-specific Tregs from PSCs (i.e., PSC-Tregs) remain undefined, especially molecular mechanisms that direct differentiation of such Tregs. Auto Ag-specific PSC-Tregs can be programmed to be tissue-associated and infiltrate to local inflamed tissue (e.g., islets) to suppress autoimmune responses after adoptive transfer, thereby avoiding potential overall immunosuppression from non-specific Tregs. Developing auto Ag-specific PSC-Tregs can reduce overall immunosuppression after adoptive transfer by accumulating inflamed islets, which drives forward the use of therapeutic PSC-Tregs for cell-based therapies in T1D.
