OBJECTIVETo explore the value of the application of oil red O staining in spinal cord injury (SCI) of rats.

METHODSWith simple randomization, 24 Spargue-Dawley male rats were divided into normal control group including 6, and SCI group including 18. Spinal cord was transected at spinal lever T10 to build SCI model. Six rats of SCI group were sacrificed randomly at 1, 2, 4 weeks after surgery. After the spinal cord tissue sections were made, oil red O staining methods were used to observe the changes at the end of transected spinal cord. Images were analyzed by Image-Pro Plus 6.0 and SPSS 20.0 software.

RESULTSThe oil red O staining of normal control group showed that white matter surrounded by myelin sheath was clear and obviously distinctive from grey matter. Uneven and strengthened staining in oil O was observed in grey matter of SCI group at 1, 2, 4 weeks post-SCI.

CONCLUSIONIt is a good method to label the myelin sheath in spinal cord and distinct white matter from grey matter by oil red O staining. Analysis of the images showed that lipid may become another target for drugs, which needs more researches.

OBJECTIVETo compare the efficacy difference in the treatment of functional dyspepsia between acupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone.

METHODSSeventy cases were randomized into an acupuncture group (35 cases) and a western medication group (35 cases). In the acupuncture group, Zusanli (ST 36) and Neiguan (PC 6) were selected. Taichong (LR 3) and Neiting (ST 44) were added for excess syndrome while Gongsun (SP 4) and Yinlingquan (SP 9) were added for deficiency syndrome. A pair of electrodes was attached to one acupoint and an assistant point (2 mm next to the acupoint centripetally) and stimulated with disperse-dense wave at 2 Hz/100 Hz, once a day. In the western medication group, domperidone was prescribed for oral administration, 10 mg each time, three times a day. In the two groups, the treatment of 5 days made one session and 4 sessions were required totally. Nepean dyspepsia index (NDI) was compared after treatment, 1, 2, 3, 4 and 5 months after treatment between the two groups respectively.

RESULTSThe score of symptom and score of life quality in NDI after treatment and at each follow-up time point were improved obviously in the acupuncture group as compared with those before treatment (all P < 0.01). In the western mediation group, the score of symptom and the score of life quality in NDI after treatment and in follow-up of 1, 2 and 3 months were improved obviously as compared with those before treatment (all P < 0.01), but the differences were not significant in follow-up of 4 and 5 months (both P > 0.05). Compared with the western medication group, the symptom score of NDI was reduced obviously after treatment and in each time point of follow-up in the acupuncture group (P < 0.05, P < 0.01), and the score of life quality was increased obviously (P < 0.05, P < 0.01).

CONCLUSIONAcupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone are effective in the treatment of functional dyspepsia. Domperidone is unsatisfactory in the long-term effect, but acupuncture achieves the positive short-term and long-term effects on functional dyspepsia.

AIM: To evaluate the diagnostic accuracy of macular ganglion cell - inner plexiform layer ( GCIPL ) measurements using high- definition optical coherence tomography ( Cirrus HD - OCT ) ganglion cell analysis algorithm for detecting early and moderate to severe glaucoma.
METHODS:Twenty normal control persons, 26 patients with early glaucoma and 29 patients with moderate to severe glaucoma were enrolled in this study. Macular GCIPL, optic nerve head ( ONH ) parameters and peripapillary retinal nerve fiber layer ( RNFL ) thickness were measured in each subject. Then all measured results of each parameter were calculated using SPSS17. 0. Areas under the receiver operating characteristic curves ( AUC) of each parameter were calculated to compare the diagnostic accuracy for detecting early and moderate to severe glaucoma.
RESULTS: For detecting early glaucoma, AUC of average RNFL and seven clock value of RNFL were the biggest ( 0. 871 and 0. 896 respectively ), the AUC of parameters in GCIPL were also significant, among them,
the average GCIPL showed bigger AUC(0. 847) than the minimum GCIPL (0. 812). For diagnosing moderate to severe glaucoma, the AUC of rim area was 0. 992, which was bigger than that of average RNFL ( 0. 991 ). The minimum GCIPL showed bigger AUC ( 0. 983 ) than the average GCIPL (0. 967). For early glaucoma diagnosis, the sensitivity of average RNFL was the highest (76. 9%), while the average GCIPL has the highest specificity (93. 5%).
CONCLUSION: AS a new diagnostic parameter for detecting glaucoma, GCIPL shows similar diagnostic potential compared with RNFL. For early glaucoma diagnosis, average RNFL is the most important parameter, while screening early glaucoma, average GCIPL should be paid more attention.

Objective To investigate the effects of myricetin (Myr) on A549 lung cancer cell proliferation and its mechanism. Method The inhibitory effects of Myr on the growth of A549 cells were investigated and its value of IC50 after 72 h incubation was measured by 3-(4,5-dimethyl-thiazolyl -2)-2,5-diphenyl tetrazolium bromide (MTT) method. The phosphorylation level of Akt protein was studied by Western blotting. Results Myr inbibited A549 cell proliferation in dose-dependent way. The IC50 value of Myr treatment for 72 h was 41.7 ?g/ml. Treatments with 32 ?g/ml Myr for 12 h significantly reduced the protein kinase B (Akt Ser473) phosphorylation. Conclusion Myr could inhibit the growth of A549 cell in a dose-dependent way. Akt phosphorylation may be the mainly molecular target of Myr in A549.

BACKGROUND: The assessment of chronic nerve root injury is mainly depend on indirect evidences of imaging results.OBJECTIVE: This study is designed to find out the relationship between the degrees of the pathological changes of nerve roots and motor evoked potential (MEP) changes due to chronic compression.DESIGN: A self-controlled trial with animals as subjects.SETTING: Spine Surgery Department of the Second Clinical Hospital of Jinan University.MATERIALS: The trial was completed in the Spinal Surgery Department of the Second Clinical Hospital of Jinan University from October 2001 to May 2003. The subjects were 30 healthy cats of either gender weighing 3 to 5 kg.INTERVENTIONS: The compression model was established by wedging a Ⅴ-shape bone flap into the right intervertebral foramens between C7, C8 and T1 vertebrae. The left foramens served as controls. The cats underwent CT examination on the 2nd, 4th, 8th and 12th postoperative week to show the foramen changes. Six randomly selected cats underwent magnetic stimulation MEP each time on the 2nd, 4th, 8th, 12th and 24th week. The injuries to the compressed nerve roots were assessed according to Mackinnon Standard and they were compared with the MEP wave.MAIN OUTCOME MEASURES: Whether the superficial magnetic stimulated MEP monitoring result was in correspondence with the pathological changes of the chronically compressed nerve roots.RESULTS: The MEP did not show any abnormal changes for Grade Ⅰ injury prolonged to 9.6- 10. 2 ms. There was almost no evoke potential at all stimulation points for grade Ⅴ nerve root injury.CONCLUSION: That the injured nerve root presents dysesthesia and normal MEP results suggests grade Ⅰ injury. Prolonged latency including prolonged F wave suggests grade Ⅱ injury. And additional amplitude decrease together with widened and unclassifiable waves implies the injury be grade Ⅲ. The prominent features of grade Ⅳ nerve injury is much more decreased amplitudes and more prolonged latency. For grade Ⅴ injury there is always disappearance of whole MEP or some potential components. The superficial magnetic stimulated MEP monitoring results are in correspondence with the pathological changes of the nerve roots due to chronic compression, which means MEP monitoring results could serve as the quantitative indication to pathological changes of nerve injury.

Objective To investigate the characteristics and prevention of deep fungal infection (DFI) complicated by severe acute pancreatitis (SAP). Methods Clinical data of 135 SAP cases admitted from Oct. 1998 to Oct. 2009 were studied, the prevention and management of SAP with DFI ( 32cases) were investigated, among them there were 19 males and 13 females. Results Seven patients (21.9%) died of these 32 cases. The SAP patients with DFI were of more critical condition, longer course and having to stay in ICU about (21±6) d, most needed surgical debridement, on long-term indwelling catheters, intubation and mechanical ventilation, parenteral nutrition, long-term use of broad-spectrum antibiotics. These patients remained in the hospital for about (78 ± 14) d. Conclusions DFI is a common complication in SAP cases causing a significant mortality hence necessitating comprehensive prevention and control measures such as proper handling of the original disease, aseptic operation, prophylactic antibiotics and antifungal agents, which can reduce the incidence and mortality of SAP with DFI.
