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.

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.

BACKGROUND: Excessive residue of dental calculus and dental plaque and scratch of Instruments on dental root surface will cause rough root surface, which will accelerate accumulation of dental calculus and dental plaque. Improved scaling can solve this problem, but the operation of ultrasonic subgingival scaling is not regular by some clinical physicians.OBJECTIVE: To study the effect on the root surfaces and the work efficacy following ultrasonic subgingival scaling with different output power and different parts of work tip.DESIGN, TIME AND SETTING: The comparison observational study was performed at the Laboratory of Medical College of Qingdao University from March to May 2009.MATERIALS: Twenty root surfaces from ten teeth extracted for severe periodontal diseases were selected, and the volume of dental calculus was basically equal. Ex vivo teeth were obtained from two male patients aged 40-50 years.METHODS: Twenty root surfaces were randomly divided into group A or group B, the high power was set as "3" gear (group A), and the low power was set as "1" gear (group B), using the side (group A1 and B1) and the top (group A2 and B2) of work tip. The time for scaling was recorded and the surface feature of all the specimens was observed under scanning electron microscope(SEM).MAIN OUTCOME MEASURES: Changes in root surface structure were observed.RESULTS: The damage of root surfaces in groups A1 and B1 was less severe, while more in groups A2 and B2. There were less calculus and plaque residual on root surfaces in group A than in group B. Cementum exfoliation was observed in group A but not in group B. The operating time of group A was significantly shorter than that of group B (P < 0.01). However, there was no significant difference between groups A1 and A2 or groups B1 and B2 (P > 0.05).CONCLUSION: Calculus and plaque can be cleaned more effectively and the damage is less severe by using the side of work tip. Although the calculus can be cleaned more rapidly by using higher power set, the damage is more severe.
