Premature birth is one of the main challenges faced by modern obstetrics, and there is still a lack of effective treatment methods. The successful pregnancy process depends on the immune balance at the maternal fetal interface, and due to the unique antigen presenting molecules and immune recognition receptors on the surface of macrophages, they play a crucial role in maternal fetal immune tolerance. The dysfunction of uterine macrophages can lead to various adverse pregnancy outcomes. This review summarizes the latest research progress on the origin of macrophages, their specialization in the uterine microenvironment, their physiological functions at different stages of pregnancy, and their role in preterm delivery.

Objective: To investigate the clinical features of children with infectious mononucleosis (IM), to compare the difference of therapeutic effects between general treatment to antiviral therapy for IM. Methods: This prospective study analyzed the clinical data and laboratory test results of 201 cases with IM in our hospital from January 1, 2016 to December 31, 2016. The follow-up period was 6-12 months. The patients were divided into two groups according to the order of admission. The clinical symptoms and laboratory test results of the two groups were observed after hospitalization. Results: Of the total of 201 patients, male to female is 1.72∶1; Age: 8 months to 13 years 6 months (average 4.8±2.8 years), The disease frequently occurred in summer and autumn, accounted for 64.18%.The major clinical manifestations was fever (97.51%), angina (79.10%), enlarged of lymph node(68.66%), eyelid swelling (67.16%), hepatomegaly (53.73%) and splenomegaly (46.77%). There was no statistical difference in duration of fever, improved angina time, lymph nodes(liver, spleen) enlargement recovery time, heterotypic lymphocytes normalization time, lymphocyte function normalization time.There was significant difference in reducing the serum/plasma or total blood EBV-DNA in the short term between antiviral group and general treatment group (P<0.01), but for the long-term reduction of EBV-DNA, there was no significant difference (P>0.05). The low affinity EBV-CA-IgG was converted to high affinity EBV-CA-IgG in 89.41% of patients after 3 months and in 98.68% of patients after 6 months. With the recovery of the disease, the positive rate of EBV-CA-IgM and EBV-EA-IgG decreased. But the positive rate of EBV-NA-IgG increased. Serum/plasma EBV-DNA was completely overcast after 3 months, but after 12 months, the patient’s total blood EBV-DNA positive rate was still 71.11%. Conclusions In general IM patients, there was no significant difference between antiviral therapy and general treatment, so antiviral therapy is not generally recommended. EBV DNA in the whole blood of patients with IM will continue to be positive more than 6-12 months, indicating that to observe changes of IM should not use whole blood samples for EBV DNA testing.

Objective To explore the value of MR T2 mapping imaging in evaluation of the effection of Zhitong-Jiangu recipes in treatment of cartilage injury in osteoarthritis.Methods The models of osteoarthritis in the knee of New Zealand white rabbits were made with intra-articular injection of papain.Totally 48 New Zealand white rabbits were randomly divided into normal control group,model control group,glucosamine hydrochloride treatment group and Zhitong-Jiangu recipes treatment group.MR T2 mapping was performed on the knee and the content of MMP-1 in articular cartilage was analyzed with immunohistochemistry 4 weeks after treatment.The differences of T2 value and MMP-1 content of articular cartilage among the four groups were compared.The correlation among the different intervention methods,MMP-1 content of articular cartilage and the T2 value of articular cartilage were analyzed.Results T2 value of articular cartilage in the model control group was significantly higher than that in the other three groups (all P＜0.01),and there was no significant difference of T2 value among the other three groups.The MMP-1 content of articular cartilage in glucosamine hydrochloride treatment group and Zhitong-Jiangu recipes treatment group was lower than that in model control group (both P＜0.05),and was higher than that in normal control group (both P＜0.05).There was no significant difference between the two groups.The relationship between MMP-1 content and T2 value of articular cartilage was nonlinear.With the increase of MMP-1 content,T2 value first increased slowly and then increased rapidly (P＜0.05).Conclusion MR T2 mapping imaging is helpful to evaluating the efficacy of Zhitong-Jiangu recipes in treatment of cartilage injury in osteoarthritis in rabbit models.The relationship between MMP-1 content and T2 value of articular cartilage may be nonlinear.

OBJECTIVE: To study the pathologic characteristics of bone marrow for CD5 positive small B cell lymphoma (SBL).
 METHODS: The pathologic profiles of 92 patients with CD5 positive SBL were retrospectively analyzed. The morphologic and immunophenotypic features were analyzed by flow cytometry and immunohistochemistry. IgH/CCND1 was examined by fluorescence in situ hybridization (FISH).
 RESULTS: A total of 92 patients with CD5 positive SBL were enrolled in this study, including 56 (60.9%) chronic lymphocytic leukemia /small lymphocytic lymphoma (CLL/SLL), 23 (25.0%) mantle cell lymphoma (MCL) and 13 other SBL (14.1%). Among the 13 other cases, 5, 4 and 4 cases were follicular lymphoma (FL), lymphoplasmacytic lymphoma (LPL) and splenic marginal zone lymphoma (SMZL), respectively. The frequency of patterns for bone marrow infiltration was as follow: diffuse pattern (19/92), mixed pattern (15/92), nodular pattern (9/92), interstitial pattern (8/92), and intrasinusodial pattern (2/92). All patients expressed CD19, CD20 and CD5. According to the immunophenotypic score system, all the CLL patients had 4-5 scores, while SMCL and other SBL patients had less than 3 scores. For the other SBL patients, 5 FL expressed CD10, while 3 FL, 1 LPL and 3 SMZL expressed CD23. There was a significant difference in the expression of CD23, sIgM, FMC7, CD11C and CD22 between the CLL and MCL groups (P<0.01). All 23 MCL patients expressed cyclin D1 and showed IgH/CCND1 gene translocation by FISH detection.
 CONCLUSION CD5 positive SBL includes a variety of types of lymphoma. Patterns of bone marrow for CD5 positive SBL are diversity. Immunophenotypic analysis by flow cytometry is essential in the diagnosis and differential diagnosis of CD5 positive SBL, especially for CLL.

Objective To assess the impact of radiation on superior epigastric vessel pedicled transverse rectus abdominal myocutaneous (TRAM) for breast reconstruction.Methods Female breast cancer patients were divided into 4 groups:group A (immediate breast reconstruction + radiation therapy,123 cases),group B (immediate breast reconstruction,262 cases),group C (radiation therapy + delayed breast reconstruction,34 cases),group D (delayed breast reconstruction,53 cases) from June 2009 to June 2012 at Department of Breast Oncology,Tianjin Medical University.Patient demographics,operative details,radiation therapy details,postoperative complications,patient-centered evaluation of aesthetic and psychological outcomes were assessed.Results The average follow-up duration was 24.98 ± 6.99 months.2.5％ patients developed delayed wound healing postoperatively.Fat necrosis and flap contracture were seen in 7.0％ and 3.6％ of all patients,respectively.Irradiated patients had a significant statistical difference in cancer staging,involved lymph nodes,tissue invasion and neoadjuvant chemotherapy (P ＜ 0.05).No significant statistical differences were observed in post-operative early complications,but in advanced stage complications.There was no significantly statistical difference in breast aesthetic outcome before and after radiation therapy within four groups.Conclusions For breast reconstruction patients,those without postoperative radiotherapy were suggested immediate breast reconstruction,and those with postoperative radiotherapy were proposed to accomplish breast reconstruction after postoperative radiotherapy.

OBJECTIVE:To provide reference for clinical desicion,drug use and ADR avoidance. METHODS:Clinical pharmacists participated in the consultations and therapy plan about a patient with hiatal hernia complicating with venous catheter- related infections. Clinical pharmacists suggested pulling out peripherally inserted central catheter(PICC)and placing a catheter again. Anti-infective therapy plan had been adjusted:vancomycin 0.5 g/time,ivgtt,q12 h;fluconazole 0.2 g,ivgtt,qd(0.4 g,ivgtt,qd on the first day),cefoperazone/sulbactam 2 g,ivgtt,q8h. Vancomycin and fluconazole were additionally used for anti- infective therapy. RESULTS:Doctors adopted the suggestions of clinical pharmacist,and pulled out PICC;and then the infection of the patient was controlled effectively. Finally,the infection had been cured. CONCLUSIONS:The participation of clinical pharmacists in the consultation contributes to rational drug use,and assists doctors to make the right clinical decisions and avoid adverse drug events.

OBJECTIVE: To detect the expression of miR-126 in different tissues and organs and the change of peripheral blood glucose in microRNA-126 knock down (miR-126 KD) mouse, and to explore the pathological significance. METHODS: Total RNAs were isolated from twelve kinds of tissues and organs in wild-type mouse (WT) and miR-126 KD mouse respectively. Th en, the expression level of miR-126 was detected by real-time PCR assay. Th e levels of peripheral blood glucose and body weight of miR-126 KD mice were measured. Th e pathologic changes of pancreas and lung tissue were observed by HE staining. RESULTS: Compared with the WT mice, the relative expression of miR-126 in spleen, liver, muscle and lung from the miR-126 KD mice were dramatically decreased respectively (P<0.05). The level of peripheral blood glucose in the miR-126 KD mouse increased significantly at seven week and sixteen week after the birth (P<0.05). HE staining showed that the pathological structure of pancreas and liver were abnormal. The body weight of miR-126 KD mice was increased obviously from thirteen week after birth (P<0.05). CONCLUSION Peripheral blood glucose levels in the miR-126 KD mouse were dramatically elevated, which might be related to the pathological changes in the structure of pancreas and liver. These results suggest that miR-126 may play an important role in the metabolism of blood glucose and the development of type 2 diabetes mellitus.

There are a lot of feasibility studies, using sentinel lymph node biopsy SLNB instead of Alex lymph node dissection (ALND), having got a conseusus that SLNB is a safe and useful method in the treatment of breast cancer. But in clinical practice, there are much false negative rate (FNR) which need to be carefully dealt with for SLNB. In order to diminish the FNR, how many nodes should be the perfect number to lower the FNR? If positive detection was found in the SLN, should ALND always be needed? And when micro metastasis was found in the post operation HE staining? Does it need further treatment? We make a review to discuss those matters.
