BACKGROUND: Chondron is a basic microanatomical unit of articular cartilage. lncreasing evidence suggests that the pericellular matrix (PCM) is a distinct functional compartment in articular cartilage, influencing the metabolic, micromechanical environment, and degeneration of chondrocytes. But the precise functions and action mechanism need further investigation.OBJECTIVE: To review the literature pertinent to the morphology, function, isolation of the chondron in articular cartilage, and its degenerative events during the progression of osteoarthritis (OA).METHODS: This review summarized the articles published in the PubMed database before July 2009. In addition, recent data and figure of our laboratory on the morphology and biomechanics of chondron and chondrocyte were supplemented. RESULTS AND CONCLUSION: The PCM is primarily characterized by the presence of type Ⅵ collagen, and these components are widespread in the expansive extracellular matrix (ECM) in newborns, while in mature the components are mainly localized to a narrow pericellular zone. The three-dimensional morphology of chondron has been recently quantified in situ with fluorescence confocal microscopy, and the mechanical properties of the isolated individual chondrons and their PCM are measured using the micropipette technique and atomic force microscopy. More studies have shown that the presence of the PCM in chondrons has a profound influence on chondrocyte gene expression. At the same time, structural, histochemical and biomechanical studies indicate the chondron and their PCM may undergo degenerative processes with osteoarthritis, similar to those occurring in the ECM, Although the precise function of the PCM is unknown, increasing evidence in vivo or in vitro suggests that the PCM is a basic microanatomical unit in articular cartilage, influencing the metabolic and micromechanical environment of chondrocytes.Department of Orthopedics, the Second Hospital of Shanxi Medical University, Shanxi Key Laboratory of Bone and Soft Tissue Injury Repair,Taiyuan 030001,Shanxi Province,China

Objective To explore a suitable mode of prenatal ultrasound diagnosis of fetal malformations with early neonatal surgical treatment. Methods Nine fetus with surgical malformations diagnosed prenatally by ultrasound in our hospital from Mar. 1998 to Dec. 2000 were analysed. Results There were two cases diagnosed in the second trimester, 7 in the third trimester, including 1 duodeneal atresia with annular pancreas, 1 abdominal wall defect, 1 congenital diaphragmatic hernia, 1 huge omphalocele, 1 high imperforate anus, 4 hydronephrosis (2 mild and 2 severe). Six cases were operated in neonatal period, two were treated conservatively, and one did induced abortion. All cases recovered except 1 death. Conclusions The mode of prenatal ultrasound diagnosis with surgery in early neonatal period is a suitable way in China before the fetal surgery is applied. It is important to make effort to increase sensitivity of sonographic diagnosis of fetal malformation and to get early treatment in perinatal period.

To investigate the effects of ischemia-reperfusion on the levels of nitric oxide and nitric oxide synthase isoforms (nNOS and iNOS), rat organotypic hippocampus slice were cultured in vitro and subjected to ischemia by oxygen-glucose deprivation (OGD) for 30 min and then placed in the normal culture condition. The ischemia-reperfusion produced a time-dependent increase in nitrite levels in the culture medium. Reverse transcriptional-polymerase chain reaction showed augmented levels of mRNA for both nNOS and iNOS when compared with control at 12 h and remained increase at 36 h after OGD (P < 0.05). The protein levels of both nitric oxide synthase isoforms increased significantly as determined by Western Blot. OGD also caused neurotoxicity in this model as revealed by the elevated lactate dehydrogenase (LDH) efflux into the incubation solution. The results suggest that organotypic hippocampus slice is a useful model in studying ischemia-reperfusion brain injury. NO and NOS may play a critical role in the ischemia-reperfusion brain damage in vitro.

Objective To investigated the role of antithrombin Ⅲ (AT-Ⅲ) levels in the early diagnosis of disseminated intravascular coagulation (DIC) in patients with sepsis and the predictive effect of AT-Ⅲ on the development of DIC.Methods A retrospective study was conducted. Patients admitted to intensive care unit (ICU) of the First Affiliated Hospital of China Medical University from January to December in 2015 were enrolled. The patients were divided into sepsis group and non-sepsis group according to the diagnostic criteria of sepsis. In addition, sepsis patients were divided into 3 subgroups according to the international society on thrombosis and haemostasis (ISTH) scores on the first day: overt DIC (ISTH ≥ 5), non-overt DIC (ISTH 1-4) and none DIC group (ISTH = 0). Blood routine test, prothrombin time (PT), fibrinogen (Fib), D-dimer, fibrin degradation products (FDP), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores, sequential organ failure assessment (SOFA) scores and ISTH scores were recorded on the first ICU day. AT-Ⅲ was recorded during 7 days. The differences were compared among these 3 groups. Correlations of AT-Ⅲ with various parameters were calculated by using Pearson correlation analysis in sepsis group and overt DIC group. Receiver operating characteristic (ROC) curves for diagnosis of DIC with AT-Ⅲ, AT-Ⅲ+PT were drawn to evaluate the diagnostic efficiency. The AT-Ⅲ levels of DIC patients were compared between early-onset DIC and late-onset DIC during their ICU stay. The change of AT-Ⅲ levels with time and prognosis in patients with early-onset DIC was compared between groups.Results Totally 445 patients were recruited, with 138 patients in sepsis group, and 307 in non-sepsis group. There were 20 patents diagnosed with overt DIC on the first ICU day, 115 patients non-overt DIC and 3 patients of none DIC. Twenty-five sepsis patients were diagnosed overt DIC during the ICU days. AT-Ⅲ level in sepsis patients on the first ICU day were lower than that in non-sepsis patients [(55.29±13.92)% vs. (76.54±12.31)%,P < 0.01]. Patients with overt DIC had a lower AT-Ⅲ level than non-overt DIC or none DIC patients [(43.85±13.00)% vs. (56.95±13.03)%, (68.00±16.52)%, bothP < 0.05]. It was shown by Pearson correlation analysis that AT-Ⅲ level of sepsis patients on the first ICU day was negatively correlated to ISTH score and PT (r value were -0.467, -0.654, bothP < 0.01). AT-Ⅲ level of overt DIC patient on the first ICU day was negatively correlated with PT (r = -0.675,P = 0.001). It was shown by ROC curve that area under ROC curve (AUC) of AT-Ⅲ combined with PT for diagnosis overt DIC in sepsis patients was higher than that of AT-Ⅲ or PT alone (0.843 vs. 0.763, 0.834), the sensitivity 90.0%, specificity 73.7%. The cut-off value for overt DIC diagnosis in sepsis patients of AT-Ⅲ level alone was 48.5%, sensitivity was 78.0%, specificity was 70.0%. On the first ICU day, AT-Ⅲ level was risen when ISTH score improved in patients with sepsis. There was similar change of AT-Ⅲ level between patients with early-onset DIC and late-onset DIC. AT-Ⅲ level increased with DIC improvement.Conclusion AT-Ⅲ level can be used for diagnosing sepsis-associated overt DIC independently or with a combination of PT. When ISTH score improved, AT-Ⅲ level was risen in patients with sepsis associated DIC.

Objective To evaluate the importance of Torch serologic screening in pregnant women and to investigate the relationship between Torch infection and pregnant women with embryo standstills as well as women with habitual abortion.Methods IIF and capture EIA were used for detection of Torch-IgG and IgM antibodies, respectively. Toxoplasma /rubella virus/CMV/HSV serologic screens were carried out in 303/278/280/236 pregnant women, 27/30/31/25 pregnant women with embryo standstills and 192/214/228/168 women with habitual abortions, respectively.Results The positive rates of toxoplasma(rubella virus, CMV, HSV)-IgG/IgM antibodies were found 2.3%/0.33% (93.2%/1.4%, 88.6%/1.1%, 93.2%/1.3%) in pregnant women, 0/0(96.7%/0, 87.1%/0, 88.0%/0,) in pregnant women with embryo standstills and 1.04%/0(98.6%/0, 91.2%/0, 94.6%/0) in women with habitual abortion, respectively. Only one serum sample was found to be true positive with rubella virus-IgM antibody in 31 Torch-IgM antibodies positive serum samples tested by other hospitals. Conclusion The necessity to screen toxoplasma antibodies in pregnant women should be evaluated due to the low incidence. It is important to determine immune status to rubella virus prior pregnancy for prenatal screening.Further studies are needed before the scheme to diagnose CMV infection during pregnancy can be decided. Serum samples tested with Torch-IgM antibodies should be re-tested with kits from other manufactures or by reference labs to avoid false positive. There are no relationships being found between Torch infection and pregnant women with embryo standstills as well as women with habitual abortion.
