Objective To find out the problems in information service for diabetic patients by investigating their use of information service. Methods The enthusiasm and channels to access information in diabetic patients and the types of information they wanted were investigated in 14 Wuhan hospitals, which were analyzed by descriptive sta-tistics, chi-square test, and Five-Point Likert Scale scoring. Results About 1/3 of the patients never initially searched the health information on diabetes,the majority of the patients acquired the health information on diabetes from medical institutions,diabetic patients did not show enough concern for the information on the etiology,influencing factors and treatment plan of diabetes. Conclusion Diabetic patients lack of enthusiasm to access information,medical staff and medical institutions are the chief force of information service for diabetic patients, and the special informa-tion accessed by diabetic patients is quite less.

BACKGROUND: Experiments has demonstrated that low-intensity pulse ultrasound stimulations(LIPUS) can accelerate bone healing. However, Its affect mechanisms on maturation of regenerated bone remain unclear.OBJECTIVE: The hypothesis that LIPUS has positive effect on maturation of regenerate bone was put forward creatively, and wants to vedfy the hypothesis by compare the difference between LIPUS intervention and no intervention.METHODS: Thlrty-six adult, healthy, New Zealand White rabbits were randomly assigned to LIPUS treatment group and control.group, with 18 animals in each group.All animals were undergone mid-diaphyeaal tibia ostactomy and were immobilized in Orthofix M103 Mini lengtheners. After a eaven-day latency period, gradual distraction of 0.5 mm per twelve hours for 10 days to produce 10 mm distraction. A 4-weeks course of LIPUS treatment was applled over the distraction site for twenty minutes daily starting immediately after the completion of distraction. At weeks 4, 8, 12 after distraction, the bone healing was evaluated by X-ray film, and total mineralized areas were measured by Image J software. The newly formed bone In the lerigthening field was harvested and stained with haematoxylin-eosin, Masson's tdchroma end VG. Thearaas of newly formed bone were measured to calculate a percentage of the total callus area.RESULTS AND CONCLUSION: Thirty-six rabbits ware included in the final analysis, At week 4 after distraction, the maturation of newly formed bone in LIPUS treatment group appeared eadier than that in the control groups. The bona callus image presented in the marginal and center region of experimental defect, increased greatly and had higher density until filled of the lengthening fields. Many bone-like masses appeared in the newly formed tissues and the tissues surrounding the bone granules partially changed Into bone-like tissues, and the rate of callus production was increased (P < 0.05). There was no significant difference between two groups at weeks 8 and 12 after distraction. Histological results showed that that new bone formation of the LIPUS group was earlier than the control group at weeks 4, 8, and 12 after distraction. The percentage of new bona on total callus area of the LIPUS group was greater than that of the control group at weak 4, but there was no obvious difference at weeks 8 and 12 after distraction. LIPUS accelerates new bone formation, increases the size of the distraction callus, exhibits highly effective in achieving maturation of bone in the animal modal with distraction osteogenesis.

Objective To explore the effect of low intensity pulsed ultrasound stimulation (LI-PUS) on the maturation of regenerate bone in a rabbit limb lengthening model. Methods Sixty skeletal mature female New Zealand white rabbits were randomly divided into an LIPUS treatment group and a control group. All rabbits were underwent mid-diaphyseal tibial osteotomy and immobilized in an Orthofix M103 Mini lengther. Gradual distraction at 0. 5 mm every 12 h for 10 d was performed at day 7 postoperatively. A 4-week course of LIPUS treatment group was applied over the distraction site for 20 min daily starting immediately after the completion of the distraction only for the treatment group. Rabbits were euthanized and the mid-diaphyseal tibia was harvested for evaluation at 4, 8, and 12 wk after the completion of the bone lengthening protocol. Radiographic analysis was performed to study the formation of bone callus using the ImageJ software at 12 wk after the completion of the bone lengthening protocol. Bone mineral density (BMD) of regenerate bone was measured by Dual energy X-ray absorptiometry (DEXA) . Torsional testing to failure was performed on the tibia specimens at 8 and 12 wk after the completion of the bone lengthening protocol. Results Radio-graphic measurement showed higher relative gray scale of bone callus in the LIPUS group than that in the control group at 12 wk (P < 0. 05) . BMD in the LIPUS group was significantly higher than that in control group at 8 and 12 wk (P < 0. 05). Biomechanical testing showed that the ultimate torque, ultimate torsional stiffness, and energy absorption at failure of regenerated bone at 8 and 12 wk in the LIPUS treatment group were better than those in the control group (P < 0. 05) Conclusion LIPUS as a biophysical stimulation may accelerate the formation and maturation of regenerate bone in rabbit tibia lengthening model.

Objective:To explore the process of regression of the hyaloid vessels and development of retinal vessels in C57BL/6J mice and the relationship between them.Methods:Seventy-five healthy SPF C57BL/6J mice on postnatal day 1 (P1) were selected and divided into control group (65 mice) and oxygen-induced retinopathy (OIR) model group (10 mice) by the random number table method.No treatment was given to control group.Mice in OIR model group were continuously fed in (75±3)% oxygen for 5 days from P7 and in normoxic condition for 5 days from P12.In control group, 5 mice were randomly selected and killed from P1 to P12 and P17, and the eyeballs were collected.In OIR model group, 5 mice were randomly selected and killed on P12 and P17, and the eyeballs were collected.The number of hyaloid arteries (HA), vasa hyaloidea propria (VHP), and tunica vasculosa lentis (TVL) of mice at different time was observed with a microscope.Another 5 adult mice aged 15 months old were selected to detect the vitreous vasculature using optical coherence tomography.The relationship between retinal astrocytes and retinal vascular development, VHP was observed by immunofluorescence staining.This study was approved by the Ethics Committee of Nankai Hospital (No.NKYY-DWLL-2021-070). The use and care of experimental animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals and the ARVO statement.Results:In control group, HA did not degenerate rapidly during eyeball development, which still presented even 15 months after birth.The number of VHP reduced rapidly from P4 to P8, and tended to be stable at 2.33±1.32 on P10 and 1.80±0.92 on P17.The number of TVL reduced rapidly from P5 to P9, reduced to 2.30±1.42 on P10, with most of the TVL blood vessels being transparent without blood supply, and decreased to 0.30±0.48 on P17.Under the guidance of astrocytes, the retinal vessels of mice grew from the optic disc to the peripheral retina from P1 to P8, forming the primary retinal vascular layer.During the development of retinal superficial vessels, VHP showed synchronous regression and the decreased density and thinner diameter in the area covered by retinal vessels.VHP detached from the retina when retinal vessels developed to the peripheral retina, and there was no structural overlap between astrocytes and VHP.In OIR model group, the number of VHP increased from 2.14±0.90 on P12 to 4.60±1.35 on P17 and the number of TVL increased from 2.90±1.55 on P12 to 5.80±1.75 on P17, showing statistically significant differences ( t=4.188, P<0.001; t=4.668, P<0.001). There was no significant difference in the number of VHP and TVL between the two groups on P12 ( t=0.429, P=0.232; t=1.116, P=0.134). The number of VHP and TVL were significantly larger in OIR model group than in control group on P17 ( t=5.422, 9.574; both at P<0.001). Conclusions:In the vitreous vascular system of mice, the regression of VHP and TVL tends to be stable 10 days after birth, and the regression of HA was not obvious.The normal regression of vitreous vessels in mice depends on the normal development of retinal vessels and astrocytes.Retinal hypoxia delays vitreous vascular regression.
