Objective: To observe the clinical efficacy of moving cupping on the back for patients with chronic fatigue syndrome (CFS)-related sleep disorders. Methods: A total of 60 patients with CFS-related sleep disorders were randomized into a control group and an observation group, with 30 cases in each group. The control group was treated with oral administration of fluoxetine hydrochloride capsule. The observation group was treated with moving cupping on the back, once every other day. The efficacy was observed after 4 weeks of treatment. The fatigue scale-14 (FS-14) and Pittsburgh sleep quality index (PSQI) were assessed before and after the treatment to evaluate the clinical efficacy. Results: The total effective rate was 93.3％ in the observation group, and 73.3％ in the control group. The difference between the two groups was statistically significant (P<0.05). After treatment, the improvement of physical fatigue value, mental fatigue value, and the total score of FS-14 in the observation group were statistically different from those in the control group (all P<0.05). The scores of subjective sleep quality, sleep latency, habitual sleep efficiency, use of sleeping medication, daytime dysfunction of PSQI and the total score in the observation group were improved more significantly than those in the control group (all P<0.05). Conclusion: Moving cupping on the back can significantly improve sleep disorders in CFS patients, and it has a better curative effect than oral fluoxetine hydrochloride capsules.

To discuss the pathogenesis of Alzheimer's disease (AD), we summarized the mechanisms of treating AD animal models by acupuncture from literatures in recent years as follows. Senile dementia rats' cognitive capabilities and memory could be improved by reduction of beta-amyloid protein, attenuation of excessive phosphorylation of tau protein, regulation of center neurotransmitter dysmetabolism, oxidation of anti-free radicals, reduction of neuron apoptosis in the cortex and the hippocampus, inhibition of glial cells' differentiation, adjustment of G protein signaling transduction, and improvement of the mitochondrial dysfunction, thus providing experimental evidence for treating AD by acupuncture.

BACKGROUND: Some studies have demonstrated that the degradation of extracellular matrix (ECM), which matrix metalloproteinases (MMPs) participates in, plays a key step in the corneal neovascularization (CNV). Tissue factor pathway inhibitor 2 (TFPI-2), a new type serine proteinase inhibitor found recently, can effectively inhibit the activity of MMPs. Whether TFPI-2 gene transfection can influence CNV is unclear.OBJECTIVE: To investigate the effect of TFPI-2 gene transfection on CNV.DESIGN: Randomized controlled experiment.SETTING: Laboratory for Department of Surgery, Wuhan Union Hospital; Central Laboratory, the Affiliated Third Hospital of Sun Yat-sen University.MATERIALS: This study was carried out in the laboratory for Department of Surgery of Wuhan Union Hospital and State Central Laboratory of the Third Hospital Affiliated to Sun Yat-sen University between June 2004 and March 2006. Sixty healthy purebred adult New Zealand rabbits of either gender, weighing 2.5 to 3.0 kg, were involved. Preoperatively, no obvious anterior segment ocular lesion was found by slit-lamp examination. pBos-Cite-neo/TFPl-2 was kindly gifted by Dr. Zhong Ren (Department of Hematology, Union Hospital). Peroxydase blocking agent, nonimmune goat serum,mouse anti-human MMP-1, 2 and 3 monoclonal antibodies, biotin labeled goat-anti-mouse IgG second antibody (Santa cruz Company) were used in this study.METHODS: Experimental intervention: Experimental rabbit models of CNV were created in each group by silver nitrate cautery. Then, the rabbit models were randomized into 3 groups and 20 rabbits for each group. Different reagents were subconjunctivally injected via many points in each group: saline in the group Ⅰ, empty vector in the group Ⅱ, plasmid encoding TFPI-2 in the group Ⅲ. Experimental evaluation: CNV growth was observed under the slit-lamp biomicroscope.The expression of TFPI-2 in each rabbit model was detected by reverse transcription-polymerase chain reaction (RT-PCR) method 2 weeks after modeling; the expression of MMPs in corneal tissue was detected by immunohistochemical method at 3,5,7,9 and 14 days after modeling.TFPI-2 gene expression was significantly higher in the group Ⅲ than in the group Ⅱ and group Ⅰ (P ＜ 0.01); The MMP-1, 2, 3 expressions in the corneal tissue were significantly lower in the group Ⅲ than in the group Ⅱ and group Ⅰ,respectively, especially MMP-1, 3.

Background Proliferative vitreoretinopathy (PVR) is a a common cause of anatomic failure in retinal detachment surgery.Proteomics is the critical method to investigate the different proteins. Objective This study was to search for related vitreous proteins in rhegmatogenous retinal detachment patients with proliferative vitreoretinopathy (PVR)and screen for the related protein expression in the vitreous with PVR. Methods Vitreous samples were obtained from 8 moderate PVR (grade B)eyes and 8 severe PVR(grade C or D)eyes during pars plana vitrectomy (PPV)for the proteomics analysis by two-dimensional gel electrophoresis coupled with mass spectrometry.Normal vitreous from 8 healthy donor eyes served as control.First dimension isoelectric focusing (IEF) was performed with the Pharmacia IPGphor in solvent B using 18 cm non-linear pH 3-10 immobilized pH gradient (IPG)strips.IPG strips were rehydrated with sample,and then IEF was performed.The second dimension 12%sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis (PAGE) was performed after the IPG strips were equilibrated.After silver staining,the gels were analyzed by the 2-DE gel analysis software.The matched spots were excised and tryptica digested in-gel.The peptides were analyzed by MALDI-TOF-MS and the MS/MS spectral were searched against the human protein databases using MASCOT.This study process complied with the Declaration of Helsinki.Wfitten informed consent was obtained from each patient prior to this trial. Results In the current study,a total of 47,184 and 336 protein spots were detected from the normal donor eyes,moderate PVR eyes and severe PVR eyes,respectively,by 2-DE gels.Among 13 protein spots with significant differences in the 3 groups,7 types of proteins were successfully identified.The results indicated that Enolase 2 was a specific protein for normal donor vitreous.whereas transthyretin monomer and retinol-binding protein(RBP) chain B were distinct proteins found in severe PVR vitreous.and prostaglandin D synthase and RBP3 precursor were common proteins with up-regulated expression in vitreous samples with moderate PVR,but down-regulated levels in vitreous samples with severe PVR.The levels of albumin and transferrin in vitreous showed dynamic elevation with the enhancement of severity of PVR.Conclusion The changes in the vitreous proteome imply that some types of vitreous proteins degrade and some common serum proteins are expressed in the vitreous body with PVR,which indicated the disruption of the blood retinal barrier in the pathogenesis of PVR.

Objective To examine the inhibitory effect of IL-2-PE40 on the mouse corneal allograft rejection. Methods A mouse corneal graft model was set up by using C57BL/6 mice as donors and Balb/c mice as recipients. In the treatment group, IL-2-PE40 (0.6 μg/g body weight) was intraperitoneally injected from the day of surgery every 12 h until rejection happened. In the control group, the equal volume of PS was injected intraperitoneally at the corresponding time points. The transplanted cornea was observed under slit-lamp twice a week and the transplanted corneal opacity and neovascularization were rated according to Horis grading standards. It led to the determination of rejection response. The survival of transplanted cornea was regarded to be stopped when the rejection occurred. The operated eyes were observed historically on the 10th, 15th, 25th and 35th day after the surgery, and the peripheral blood was collected for measurement of T cell subgroups and T lymphocyte colonies. Results The survival time of cornea in the treatment and control groups was (30.2±2.9) days and (15.1±2.1) days respectively. In the control group, rejection occurred on the 15th day after the surgery, CD4~+ cells started rise right after the surgery and increased most obviously on the 15th day [(63.9±4.0)%] and decreased afterwards. CD4~+ cells in the treatment group were increased slightly [(42.6±4.0)%] on the 15th day. The number of CD4~+ cells in the treatment group was obviously less than in the control group (P<0.01). No significant changes in CD8~+ cells were observed in both groups. The number of T lymphocyte colonies in the control group was increased at the beginning and dropped then. No obvious change was found in the treatment group. The number of T lymphocyte colonies in the treatment group was significantly less than in the control group (P＜0.01). Conclusion IL-2-PE40 is a highly specific immunosuppressive agent. It can delay the development of corneal graft rejection and reduce the percentage of T-helper cells significantly. It also works to weaken the forming capacity of the peripheral T lymphocyte colonies.
