Our country has been using maturity grading method, which was proposed by Grammum in 1979, to evaluate the placental function. However, this method is subjective to consequence because it totally depends on the observation and experiences of clinicians. With the development of ultrasound technology, therefore, we reviewed more novel applications in other aspects of placenta (such as blood flow, vascularization, etc). Over the past years, scholars in the world have done a lot of research around these topics. In this review we introduce placental maturity grading with B-mode ultrasound, placental vascularization qualitative and quantitative analysis with three-dimensional Doppler ultrasound and placental volume measurement, respectively.

BACKGROUND:Inducing factor and chondrogenic microenvironment is a primary factor, which influences chondrogenic differentiation and chondrogenesis of bone marrow-derived mesenchymal stem cells (MSCs). OBJECTIVE:To explore the feasibility of in vivo chondrogenesis by co-culture of bone marrow-derived MSCs and chondrocytes. DESIGN, TIME AND SETTING:A randomized controlled animal experiment was performed at Department of Pathology, Stomatological Hospital, Fourth Military Medical University of Chinese PLA between September 2004 and March 2005. MATERIALS:Fifteen New Zealand rabbits of clean grade were used for cell-scaffold construct transplantation. The rabbits were randomly divided into co-culture, chondrocyte, and bone marrow-derived MSC groups, with 5 rabbits in each group. Five neonatal New Zealand rabbits, aged 1-3 days, were used for isolation and culture of bone marrow-derived MSCs and chondrocytes. Polyglycolic acid (PGA) scaffold material (Shanghai Yikuo Company, China) has a fiber diameter of 15 μm, with an average interval of 150-200 μm, an interval porosity of 97% and 2-mm thickness. METHODS:In the co-culture group, bone marrow-derived MSCs and chondrocytes were mixed at a ratio of 3:1. The mixed cells were seeded onto a pre-wetted PGA scaffold (5 mm×5 mm )at the ultimate concentration of 6.0×1010 L-1. Dulbecco's modified Eagle's medium (DMEM) supplemented with fetal bovine serum was dropwise added to peripheral compound for 1 week of culture. In the chondrocyte, and bone marrow-derived MSC groups, chondrocytes and bone marrow-derived MSCs of the same ultimate concentration were seeded respectively onto the PGA scaffold. Then, the cell-scaffold constructs were transplanted into subcutaneous tissue of adult rabbits. MAIN OUTCOME MEASURES:Gross observation and hematoxylin-eosin & Masson staining of neo-cartilage were performed after in vivo culture for 8 weeks. RESULTS:Cell in all groups had a fine adhesion to the scaffold. In both co-culture and chondrocyte groups, the cell-scaffold constructs could maintain the original size and shape during in vivo culture and formed homogenous mature cartilage after 8 weeks of in vivo culture. Furthermore, the neo-cartilages in both groups were similar to each other in gross appearance and histological features. In the bone marrow-derived MSCs group, connective tissue rather than cartilage was found during in vivo culture. CONCLUSION:Chondrocytes can provide a chondrogenic microenvironment to induce a chondrogenic differentiation of bone marrow-derived MSCs and thus promote the chondrogenesis of bone marrow-derived MSCs in vivo.

Objective:
To understand the survival status and influencing factors of HIV/AIDS patients with highly active antiretroviral therapy ( HAART ) among drug users in Yili Prefecture, Xinjiang from 2005 to 2019, so as to provide references for reducing AIDS mortality.
Methods :
The demographic information, clinical stage, baseline CD4+T lymphocyte ( CD4 ) level and treatment status of HIV/AIDS patients with HAART in Yili Prefecture from 2005 to 2019 were collected through AIDS Antiretroviral Therapy Information System. The survival rate was calculated by the life table method. The influencing factors for survival time were analyzed by Cox proportional hazard regression model.
Results:
Totally 1 935 patients were recruited, the median age receiving HAART was 37 years old and the median CD4 counts was 293/μL. The cumulative survival rates at 1, 5, 7 and 10 years were 97%, 78%, 73%, and 66%, respectively. The multivariate Cox proportional hazards regression analysis showed that the patients with body mass index of 18.5-<28.0 kg/m2 ( HR: 0.391-0.656, 95%CI: 0.234-0.958 ), baseline CD4>200/μL ( HR: 0.354-0.667, 95%CI: 0.232-0.841 ) , or missed medication in the last 7 days ( HR=0.009, 95%CI: 0.001-0.061 ) had lower risk of death; the patients with WHO clinical stage of Ⅱ-Ⅳ ( HR: 1.479-2.311, 95%CI: 1.004-3.288 ) or treatment delay ≥1 years ( HR: 1.287-1.388, 95%CI: 1.029-1.826 ) had higher risk of death.
Conclusions
The 5-year cumulative survival rate of HIV/AIDS patients with HAART in Yili Prefecture is 78%. Body mass index, baseline CD4 level, WHO clinical stage, treatment delay and missed medication in last 7 days were the influencing factors for survival time.

Objective To observe the changes of the peripheral blood T lymphocyte subsets following acute spinal cord injury and investigate the possible mechanism of these changes. Methods The SCI models of rats were made by Allen's method. Forty SD rats were divided into four groups, ie,normal control group, sham operation group, 100 g·cm group and 200 g·cm group. The expressions of CD4 and CD8 subsets of the peripheral blood T lymphocyte of the injured rats were determined by immunofluorescence labelling and flow cytometry at different times after injury. Results It was found that the expression of CD4 was significantly reduced to (30.40±4.76)% in 100 g·cm group and to (26.54± 9.34) % in 200 g·cm group, which were significantly lower than that of normal control group ( P <0.01 ). At 36 hours after injury, the ratio of CD4/CD8 was significantly reduced to 1.81 ± 0.55 in 100 g·cm group and and 1.29 ± 0.50 in 200 g·cm group, with statistical difference (P < 0.05).Conclusions The immunoreaction is significantly depressed at the early stage of acute spinal cord injury. The severer injury results in more significant decrease of CD4 and ratio of CD4/CD8. The changes of CD4 and CD4/CD8 ratio can be used to indicate the severity of spinal cord injury.
