Objective To investigate the value of self-made minimally invasive cancellous bone harvester.Methods From February 2007 to October 2008,cancellous bones of 35 cases were obtained by the self-made minimally invasive cancellous bone harvester from the area between the point 1 cm posterior to the anterior superior iliac spine and the tubercle of iliac crest.ResultsThe average amount of harvested bone is 2.37 cm3(range 1-4 cm3).The operation time ranged 3-5 min,and the blood loss was 1-2 ml.The incidence rate of complications was 5.7%(2/35).Conclusions The minimally invasive bone harvester is safe and reliable.It can be used for some bone grafting surgeries.

0.05). The daily average intake of protein, fat and carbohydrate was similar to the RNI. The energy percentage of three meals was 4∶4∶2. Conclusions The incidence rate of hyperlipemia is high. It is a dangerous module which affects the health of the old. Thus, the diet for the old should be improved for their health.

0.05). But less oxidative DNA damage induced by 10?mol/L H2O2 was found in the 7.5 mg/kg bw VC supplemented group (72.6AU) than in VC deficient (127.3AU),125 mg/kg bw (121.0AU ), and 250 mg/kg bw (133.0AU) groups (P

Objective To approach the effect of Silkworm Cocoon,Portulaca oleracea on the glucose and lipid metabolism to type 2 Diabetic rats. Methods type 2 diabetic rat models induced by STZ were randomly divided into diabetes model group,Silkworm Cocoon group,Portulaca oleracea group,Silkworm Cocoon+Portulaca oleracea group,and normal contrast group,after eight weeks' intervention,We analyze blood glucose(GLU), triglyeeride(TG), SOD, GSH, MDA, calculate, the indexes of insulin resistance (HOMA-1R). Results compared with diabetes model group, the GLU in Silkworm Cocoon+Portulaca oleracea group decrease 53.3%(P<0.01) : The TG decrease 44.1%(P<0.05). the Homa-IR decrease groups has no statistic difference. Conclusion The mixture group can obviously improve the glucose and lipid metabolism、 relieve insulin resistance、 significantly increase antioxidatian、 decrease the products oflipid peroxide.

Objective:To study the effect of natural antioxidant ?-carotene(?-C) combined with vitamin E and C supplement on cellular oxidative damage in aged people. Method:Three hundred subjects aged from 60 to 75y,128 males and 172 females were randomized into 5 groups:group 1(VE 200mg/d+VC 300 mg/d+?-C 16.7 mg/d) ,group 2(VE 200 mg/d+VC 300 mg/d+?-C 8.4 mg/d) ,group 3(VE 200 mg/d+VC 300 mg/d+?-C 5.6 mg/d) ,group 4(VE 200mg/d+VC 300mg/d) ,group 5(VE 5 mg/d) . The trial lasted 16 weeks. All subjects were asked to record the nutrients intake daily. The investigators followed-up and supervised the subjects irregularly. The samples of blood and urine were collected at the beginning and end of the trial. The proliferation of lymphocytes was detected by MTT and H2O2-induced erythrocyte hemolytic degrees were measured before and after the trial. Thefluidity of erythrocyte membrane was evaluated by fluorescence polarization(?) and microviscosity(?) . O6-MeG was analyzed by high performance capillary zone electrophoresis. Results:The proliferation of lymphocytes was increased and H2O2-induced erythrocyte hemolytic degrees were decreased from group 1 to group 4 at the end of trial with significant difference compared with control group 5. The ? and ? values were lower in 1 to 4 groups at the end of trial. O6-MeG was significantly lower in group 1 to 4 group at the end of trial,and group 1 lower than group 4. Conclusion:Different doses of natural antioxidant ?-carotene supplement combined with vitamin E and C could improve the function of erythrocyte and the proliferation of lymphocytes,and decrease DNA alkylating damage.

Infant nutritional status evaluation is a basic experimental skill in the experimental teaching of nutrition and food hygiene. The construction of this virtual simulation experiment can solve the problems of activeness and poor coordination of infants and young children in the actual operation of the experiment. And based on the application of this virtual simulation project, the experimental teaching method of preventive medicine was explored. This experiment adopted online and offline mixed teaching method, which enriches teaching measures and strengthens the standardized process of infant nutritional status evaluation. After 3 semesters of practice from spring 2018 to spring 2020, the proportion of students who achieved excellent grades was 30.09% (34/113), 56.02% (279/498) and 66.79% (1 080/1 617), respectively, which increased significantly year by year ( Ptrend < 0.001). Among all the 2 228 students, 1 983 students (89%) believed that this experimental teaching could better cultivate the ability of autonomous learning. Through the study of virtual simulation experiments, students have improved their subjective initiative, and laid a foundation for the improvement of students' overall quality and the requirements of school elite education.

Objective:To evaluate the efficacy and safety of oral anisodine hydrobromide tablets in the treatment of nonarteritic anterior ischemic optic neuropathy (NAION).Methods:A multicenter nonrandomized controlled trial was conducted.A total of 282 acute NAION patients (282 eyes) were recruited from 16 hospitals in China from July 2020 to May 2021.Patients were divided into two groups according to treatment methods, which were control group (124 cases, 124 eyes) receiving regular treatment including citicoline sodium plus Ginkgo biloba leaf liquid extract or Ginkgo biloba leaf extract tablets plus mecobalamin, and experimental group (158 cases, 158 eyes) receiving treatment in control group plus oral anisodine hydrobromide tablets 1 mg, twice daily for 2 to 3 months.Best corrected visual acuity (BCVA), visual field index (VFI), peripapillary retinal nerve fiber layer (pRNFL) and radial peripapillary capillary vessel density (RPC) were assessed at 1, 2, 3, and 6 months after enrollment using the standard decimal visual acuity chart, 750i Humphery visual field analyzer, Cirrus HD-OCT 4000/Cirrus HD-OCT 5000, RTVue-XR optical coherence tomography respectively.The primary outcomes were BCVA and VFI, and the secondary outcomes were pRNFL, RPC, and the side effects during the follow-up.The study adhered to the Declaration of Helsinki.All patients were fully informed about the treatment and purpose of this study and voluntarily signed the informed consent form.The study protocol was approved by Chinese PLA General Hospital (No.S2020-021-01). Results:In all, 242 patients (242 eyes) completed the follow-up of BCVA, and 98 patients (98 eyes) completed the VFI follow-up.In terms of visual function, BCVA and VFI improved significantly over time in the two groups, and BCVA and VFI were better in experimental group than in control group at various follow-up time points (all at P<0.05). In terms of structure, pRNFL gradually decreased in both groups with the extension of treatment, and pRNFL was significanthy thinner in experimental group than in control group at various follow-up time points (all at P<0.05). There was no significant difference in RPC between the two groups at the last follow-up ( P>0.05). There were two cases with side effects and one case was discontinued due to side effects 25 days after enrollment. Conclusions:Oral anisodine hydrobromide can improve visual acuity and visual field in NAION and accelerate the regression of optic disc edema, with good safety.
