OBJECTIVEThis study is performed to investigate the cell topographies and biomechanical properties of two different types of temporomandibular joint (TMJ) discs from goats by using JPK Nano Wizard 3 biological atomic force microscopy (AFM). This process provides a guideline for selecting seed cells for TMJ disc tissue engineering.

METHODSTMJ disc cells from primary goats were cultured by monolayer culture method. AFM was used to contact scan the topographies of the two types of TMJ disc cells under physiological environment. Approximately 20 chondrocyte-like and fibroblast-like cells were selected randomly to plot the force-versus-distance curves of the cytoplasm and nucleus. Young's modulus and adhesion were analyzed by JPK Data Processing.

RESULTSThe triangle-shapednucleus of the chondrocyte-like cell occupied a large portion of the cell. Cytoskeleton was arranged dendritically on the surface. Pseudopodia were extended from cell edges. The spindle-shaped nucleus of the fibroblast-like cell occupied a significantly larger region compared with the cytoplasmic region. Cytoskeleton was arranged regularly. Cell edges were smooth with less pseudopodia extended. No difference was found in the surface roughness between the two types of cells. According to the force-versus-distance curves, the Young's moduli of the two types of cells were not statistically different (P>0.05), but differences were found in the cytoplasmic regions (P=0.047). No statistical difference was found in the adhesions between the two types of cells (P>0.05).

CONCLUSIONThe AFM topography and curves were compared and analyzed. The two types of TMJ disc cells exhibited significantly different topographies, but only slight difference in their mechanical abilities.

BACKGROUND:Our preliminary studies have shown that basic fibroblast growth factor can induce the differentiation of bone marrow mesenchymal stem cells into disc cells of the temporomandibular joint, and for basic fibroblast growth factor, 10μg/L is superior to 5μg/L in col agen synthesis.
OBJECTIVE:To observe ultrastructural changes of bone marrow mesenchymal stem cells after being induced by different concentrations of basic fibroblast growth factor.
METHODS:We cultured primary sheep bone marrow mesenchymal stem cells and selected passage 3 and 4 cells at good growth state. Bone marrow mesenchymal stem cells were stimulated with 5 and 10μg/L basic fibroblast growth factor and their growth state was observed under inverted phase contrast microscope. Uninduced cells served as controls. The slides with cellcrawling pieces were stained with Safranin O, picrosirius and type I col agen immunohistochemistry at days 7, 14 and 21, respectively. Simultaneously we col ected the cells at day 21 to observe the ultrastructural changes of bone marrow mesenchymal stem cells.
RESULTS AND CONCLUSION:After being induced with different concentrations of basic fibroblast growth factor, bone marrow mesenchymal stem cells were able to differentiate into disc cells of the temporomandibular joint;and after being induced with 10μg/L basic fibroblast growth factor, cells were more like fibroblast-like cells of the temporomandibular joint disc. These findings indicate that bone marrow mesenchymal stem cells have morphological basis for differentiation to the fibroblast-like cells of the temporomandibular joint disc.

Objective To explore the efficacy and safety of combined intravenous and intrathecal vancomycin in treatment of patients with intracranial infection after craniotomy. Methods Clinical data of a total of 60 consecutive patients with intracranial infections after cranial operation admitted to Department of Neurosurgery of Nanfang Hospital of Southern Medical University from June 1st 2013 to June 1st 2015 were retrospectively analyzed. The patients were divided into two groups: intravenous injection only (n = 25) and combined intravenous and intrathecal injection (n = 35). In both groups of patients intravenously given vancomycin hydrochloride 500 kU every 6 hours as well as third or fourth generation of cephalosporins or meropenem. In combined intravenous and intrathecal injection group, in addition to 20 mg vancomycin was slowly injected via lumbar puncture after release of cerebrospinal fluid (CSF) once a day. The clinical efficacy and complications of the two groups were compared. Results The recovery rate in the combined intravenous and intrathecal injection group was significantly higher than that in the intravenous injection only group (94.3% vs. 76.0%, χ2 = 4.220, P = 0.040). Lowering of white blood cell count in combined intravenous and intrathecal injection group was significantly earlier than that of the intravenous injection only group (time to become normal: 8 days vs. 13 days). The time of recovery in combined intravenous and intrathecal injection group was significantly shorter than that of the intravenous injection only group (days: 9.9±0.7 vs. 13.4±1.1, t = -2.716, P = 0.009). There were 3 patients who experienced nerve root irritation symptoms in combined intravenous and intrathecal injection group. Symptomatic treatment was given and injection speed was slowed down for these patients. There were no severe complications, such as coma, epilepsy or death in both groups. Conclusion Combined intravenous and intrathecal injection of vancomycin could be a safe and effective therapy for intracranial infection after craniotomy.

BACKGROUND:Perioperative high hidden blood loss affects the recovery of joint function after total hip replacement. OBJECTIVE:To analyze the reliability of the Mini Nutritional Assessment on evaluating the nutritional status in elderly patients with femoral neck fracture on admission, and to investigate the effect of nutritional status variation on hidden blood loss after total hip replacement. METHODS:234 elderly patients with femoral neck fracture underwent total hip replacement. By using Mini Nutritional Assessment, patients were randomly divided into three groups:wel-nourishment group (n=52), malnourishment at risk group (n=92), and malnourishment group (n=90). The results were used to analyze the correlation of Mini Nutritional Assessment and serological nutrition indicators, and to hidden blood loss. RESULTS AND CONCLUSION:(1) Hidden blood loss:101 patients suffered from high hidden blood loss. Hidden blood loss, its proportion to total blood loss and incidence of high hidden blood loss gradual y increased with the deterioration of the nutritional status (P<0.05). (2) Mini Nutritional Assessment:Pre-operative Mini Nutritional Assessment score, and the incidence of hidden blood loss evaluated by albumin, prealbumin, transferrin, lymphocyte count, the percentage of lymphocytes and hemoglobin was significantly higher in patients with high hidden blood loss than those with low hidden blood loss (P<0.01). (3) Results of correlation analysis:High hidden blood loss was positively correlated with pre-operative Mini Nutritional Assessment, albumin, prealbumin, transferrin, the percentage of lymphocytes and hemoglobin (P<0.05). (4) These findings confirm that risk evaluation with Mini Nutritional Assessment is a reliable method to assess the nutritional status in elderly patients undergoing total hip replacement. Its combination with various serum nutrition indicators can determine high hidden blood loss and the prognosis.

OBJECTIVETo investigate the effects of initiative and passive perioperative function exercises on hidden blood loss (HBL).

METHODSTwo hundreds and thirty elderly patients with hip fractures aging from 67 to 87 years (average age of 73.6 years) who underwent total hip replacement were included. By the intensity and the manner of perioperative function exercises, patients were divided into four groups: little initiative function exercises group (group A, n=51), little initiative and passive function exercises group (group B, n=54), normal initiative function exercises group (group C, n=65), normal initiative and passive function exercises group (group D, n=60). The true total blood loss, HBL and their proportion on the original blood volume and total blood loss was calculated depending on height, weight, intra-operative blood loss, post-operative blood loss, pre- and post-operative hematocrit, and blood transfused. According to the proportion of mean HBL on total blood loss, patients were divided into low HBL group and high HBL group. The data were analyzed by t test.

RESULTSThe mean HBL was 517 ml, 41.9% of the total blood loss. Thereinto, the mean HBL was 695 ml in group A, 49.3% of the total blood loss, the prevalence of high HBL was 66.7% (34/51); the mean HBL was 625 ml in group B, 46.9% of the total blood loss, the prevalence of high HBL was 59.3% (32/54); the mean HBL was 446 ml in group C, 38.4% of the total blood loss, the prevalence of high HBL was 30.8% (20/65); the mean HBL was 346 ml in group D, 32.3% of the total blood loss, the prevalence of high HBL was 20.0% (12/60). Mean HBL, mean HBL/total blood loss, prevalence of high HBL were lower in group C than that in group A and group B (all P<0.05); and were lower in group D than that in group C (all P<0.05). The prevalence was 57.4% (132 cases) in low HBL group, and 42.6% (98 cases) in high HBL. The proportion of little initiative function exercises patients in high HBL group was obviously higher than that in low HBL group (P<0.05).

CONCLUSIONSThe intensity and the manner of perioperative function exercises are strongly associated with the HBL in elderly patients with total hip replacement. The initiative combined with the passive function exercises could be effectively prevent and reduce the incidence of high HBL.
