Objective To evaluate the value of MRI in diagnosing the bucket handle tear (BHT) of the knee meniscus.Methods Eighty four knees which underwent both MRI and arthroscopy (AS) examinations were analyzed. Results of AS were used as golden standard to evaluate the results of MRI. The evaluating criteria included primary reports, central displaced fragments of meniscus (CDFM), double posterior cruciate ligament sign (DPCLS) and the absent bow tie sign (ABTS). Results For MRI diagnosing BHT, the sensitivity and specificity of primary reports were 43% and 87%, respectively; the sensitivity and specificity of CDFM were 72% and 87%, respectively; the sensitivity and specificity of the DPCLF were 31% and 97%, respectively; and the sensitivity and specificity of the ABTS were 71% and 69%, respectively.Conclusions When MRI was applied to diagnose BHT, the CDFM had higher sensitivity and specificity, while the ABTS had higher sensitivity and lower specificity. The DPCLF had the highest specificity and the lowest sensitivity.

Objective To study the value of detection of C- reactive protein(CRP), serum glucose concen-tration and APACHE Ⅱ grade for estimating inflammation, pathogenetic condition and prognosis of systemic inflam-matory response syndrome (SIRS) patients.Methods 50 SIRS patients in ICU were selected and were divided into S1 and S2 subgroup according to SIRS diagnosis standard, and 18 patients developed MOBS.30 patients without SIRS, were selected as control group.Detection of CRP, serum glucose concentration and APACHE Ⅱ grade were per-formed.Results CRP(76.19±11.98 mg/L vs.14.04±5.70 mg/L) ,serum glucose concentration(7.10±1.30 mmol/L vs.5.32±1.09 mmol/L) and APACHE Ⅱ grade (20.06±6.39 vs.7.90±3.54) of SIRS group were higher than that of non-SIRs group (P<0.01).CRP, serum glucose concentration and APACHE Ⅱ grade all are higher in group S2 than that of group S1 (91.25±9.89 mg/L vs.62.29±10.38 mg/L,8.32±2.40 mmol/L vs.7.10±1.69 mmol/L,26.72±5.14 vs.18.37±5.70).MOBS incidence and case fatality in S2 subgroup (12/15 and 6/35) were higher than that of S1 subgroup(10/15 and 3/35 ) (P<0.01 ).Conclusion CRP, serum glucose concentration and APACHE Ⅱ grade are increased in SIRS patients and with their increasing, MOBS incidence and case fatality were also increasing.CRP, serum glucose concentration and APACHE Ⅱ grade are significant factors in estimating SIRS patients pathogenetic condition and their prognosis.

The psychiatric problem has become a global public health issue. The model of mental health service advocate that“Treatment of disease occurred in the hospital, but rehabilitation and management in the community”. This brings great challenge to the community health service center. By comparing the domestic and foreign mental health service system, this paper discusses the necessity of carrying out the standardized training of general practitioners in psychiatry and psychology.

OBJECTIVE To study the risk factors of extended-spectrum beta-lactamases(ESBLs) producing bacteria infection in children,and provide reference to prevent and control the prevalence of bacterial strain of ESBLs.METHODS In a case and control studys the samples were selected randomly from 2007 to 2009 in the Children′s Hospital of Shanxi Province.The samples of case and control were all 100.RESULTS ?2 Test showed that boy and baby,previous history,pneumonia,medical ward,hospital infection and using antibiotics before admission to hospital were the risk factors;t-test showed that high white blood cell and neutrophil were the protective factors;Logistic regression showed that boy,previous history,hospital infection,using antibiotics before admission to hospital and medical ward were the risk factors and anal tube was a protective factor.CONCLUSIONS Increasing the rate of bacteriological test to the children who have the relative risk factors is very important to prevent and control the prevalence of ESBLs strain.

Prion diseases are infectious and fatal neurodegenerative diseases. The pathogenic agent is an abnormal prion protein aggregate. Microglial activation in the centre nervous system is a characteristic feature of prion disease. In this study, we examined the effect of PrP 106-126 on PrP mRNA gene expression in Mouse microglia cells BV-2 by real-time quantitative PCR. PrP mRNA expression level was found to be significantly increased after 18 h exposure of BV-2 cells to PrP 106-126, with 3-fold increase after 18 h and 4.5-fold increase after 24 h and BV-2 cells proliferating occurred correspondingly. Our results provide the first in vitro evidence of the increase of PrP mRNA levels in microglial cells exposed to PrP 106-126, and indicate that microglial cells might play a critical role in prion pathogenesis.

Objective To explore the protective effect and mechanism of gardenoside on the damage of dopaminergic neurons induced by lipopolysaccharide (LPS). Methods Both neuron-enriched cultures and neuron-astrocyte cultures were pretreated with vehicle or gardenesides ( 10, 20 and 40 mg/L) for 30 min at 37℃. The culture media were subsequently renewed in order to remove gardenesides. LPS was then added into all culture media at a final concentration of 10 mg/L Twenty-four hours later, the culture media was collected to measure TNF-α, NO, IL-6, GDNF and MMP-9; the cells were collected to count the number of cells labeled with an antibody against tyrosine hydroxylase (TH) and to assess the expression of TH mRNA using reverse transcription-polymerase chain reaction. Results Gardeneside didn't promote the survival of dopaminergic neurons in neuron-enriched culture, but significantly increased the survival of dopaminergic neurons in neuron-astrocyte culture, compared with the vehicle group, the survival of dopaminergic neurons increased from 203.0%±17.4% to 256.7%±15.2% ( F = 17.22, P = 0.001 ) in 40 mg/L gardenaside group. The amount of TNF-α, NO and GDNF released from the neuron-astrocyte cultures after 24 h of addition of LPS was not changed significantly, while the expression of IL-6 and MMP-9 was increased significantly. In this study, the gardenoside concentration-dependently attenuated the LPSinduced increase of the expression of IL-6 and MMP-9, compared with the vehicle group, the expression of IL-6 and MMP-9 decreased to 67.2%±6.4% (F= 12.89,P =0.001 ), 77.3%±9.8% (F =8.27,P = 0.001 ) respectively in 40 mg/L gardenoside group. Conclusions Astrocytes play a neuroprotective role on dopaminergic neurons, which is decreased by LPS via inducing the secretion of pro-inflammatory factors. Gardeneside may protect dopaminergic neurons from LPS-induced injury in an astrocyte-dependent manner and it inhibits the production of proinflammatory factors instead of promoting the secretion of GDNF. From the point of view that a very low toxicity of gardenesides has been well documented, this report may reveal a new way of developing therapeutic interventions for inflammation-related diseases such as Parkinson's disease.

Objective To investigate the in vitro effects of KAAD-cyclopamine, a specific inhibitor of hedgehog signaling pathway, on the growth and apoptosis of human squamous cell carcinoma cell line A431. Methods A431 cells were cultured and treated with KAAD-cyclopamine(0.5, 1, 2, 5 μmol/L).Then, MTT assay was used to detect the proliferation of A431 cells, and light microscopy to observe cell morphology at different time points with a 24-hour interval. Flow cytometry was used to assess cell cycle,and annexin-V/propidium iodide double staining to evaluate the apoptosis in these cells after 48 hours of treatment with KAAD-cyclopamine. Results KAAD-cyclopamine of 0.5, 1, 2 and 5 μmol/L inhibited the proliferation of A431 cells by (7.0±2.3)%, (20.6±2.8)%, (48.3±3.4)% and (61.6±3.3)%, respectively (F = 49.92, P＜0.01 ). Furthermore, in the presence of KAAD-cyclopamine of 5 μmol/L, on day 1, 2, 3, 4,and 5 the proliferation of A431 cells was suppressed by (18.5±2.6)%, (56.1±3.7)%, (65.4±2.8)%,(71.2±1.9)% and (75.9±3.0)%, respectively, the difference was significant among these time points(F =16.32, P＜0.01 ). Statistical analysis showed that KAAD-cyclopamine downregulated the growth of A431 cells in a dose-and time-dependent manner (r = 0.91, 0.86, P＜0.01 and 0.05, respectively). Light microscopy revealed typical morphological changes of cell damage in A431 cells. KAAD-cyclopamine in creased the percentage of cells in G1 phase from (51.8±2.9)% to(76.2±1.8)% (F = 26.34, P＜0.01 ), the proportion of hypoploid cells from (1.7±0.3 )% to (8.7±0.2)% (F = 6.32, P＜0.05 ), which suggested that KAAD-cyclopamine could arrest A431 cells in G1 phase of the cell cycle. The apoptosis ratio in KAAD-cyclopamine-treated cells was significantly higher than that in the untreated control [ (46.2±2.8)% vs (18.5±3.1 )%, F = 32.01, P＜0.01 ]. Tomatidine treatment did not affect the proliferation or apoptosis of A431 cells (both P＞0.05).Conclusion KAAD-cyclopamine can markedly suppress the proliferation and induce apoptosis of A431 cells.
