OBJECTIVETo observe the clinical therapeutic effects on cervical spondylosis of vertebral artery type treated with both acupuncture and mild moxibustion and investigate the mechanism of action.

METHODSSixty cases were randomly divided into the combined therapy group of acupuncture and mild moxibustion (combined therapy group) and the acupuncture group, 30 cases for each group. In combined therapy group, Baihui (GV 20), Fengchi (GB 20) and cervical Jiaji (EX-B 2) were punctured, and Baihui(GV 20), Dazhui (GV 14), Mingmen (GV 4), Shenque (CV 8) and Guanyuan (CV 4) were treated with mild moxibustion; in acupuncture group, acupuncture was simply applied, the acupoints selection and manipulation were the same as those in the combined therapy group. The average velocity meter and the resistive index of vertebral and basal arteries were observed before and after treatment by TCD examination, the therapeutic effects and clinical symptom-sign scores were observed too.

RESULTSThe total effective rate was 93.3% (28/30) in combined therapy group, and 73.3% (22/30) in acupuncture group. The therapeutic effect in combined therapy group was superior to that in acupuncture group (P < 0.05). The improvements of symptom-sign scores in two groups after treatment were more significant than that before treatment, and the score in the combined therapy group was superior to that in acupuncture group (P < 0.05). The average velocity meter and the resistive index of vertebral and basal arteries after treatment were improved in both groups, in which, the improvement in combined therapy group was more apparent (all P < 0.05).

CONCLUSIONThe therapeutic effects on cervical spondylosis of vertebral artery type treated with both acupuncture and mild moxibustion are preferable; by this therapy, the average velocity meter of vertebral and basal arteries are accelerated and the resistive index is decreased.

OBJECTIVETo evaluate a modified Mitchell's technique for epispadias repair.

METHODSThree patients with epispadias were undergoing the treatment. It was performed to form a penile pedicled flap or scrotal mediastinum flap for the repair of the urethra and the urine was drained through a perined "U" shaped stent.

RESULTSAll of the patients were successfully treated in one-stage with a good appearance and a matching opening of the urethra.

CONCLUSIONThe above mentioned technique could be a good method for epispadias repair.

Objective:To determine the optimal condition for mouse embryonic stem cells (mESC) culture with stirred bioreactor,and to develop a method for mass production of embryoid bodies (EB). Methods:The different initial cell concentrations of mESC and the initial stirring speed of bioreactor were investigated to determine the optimal condition for EB formation. Induced by ascorbic acid,the differentiation of EBs formed in stirred bioreactor into cardiomyocytes was compared with EBs formed in Petri dish. Immunofluorescence staining and RT-PCR were used to identify the cardiomyocytes derived from mESC. Results:The formation of a large number of uniform relatively EBs was achieved in stirred bioreactor when mESC were seeded initially with 1?105~3?105 cells/ml and stirring speed was set to 15~30r/min. Most of cells in the EBs formed in bioreactor were viable. EBs produced in bioreactor differentiated into cardiomyocytes more efficiently compared with EBs from Petri dish. The cardiac specific genes were expressed in ESC-derived cardiomyocytes. Conclusions:Stirred bioreactor culture could enhance the efficiency of EB formation and differentiation into cardiomyocytes,which may be a more ideal culture system for EB formation.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

OBJECTIVE: To observe the impact of energy saving light,incandescent light and circadian light on the ethology of depressive rats and explore its possible mechanism on affecting the secretion of melatonin. METHODS: Thirty rats aged 6weeks were randomly selected from 40 specific pathogen free health female SD rats after they adapted to the living environment,depressive rat models were established in the rats by bilateral ovariectomy combined with isolated living and chronic unpredictable mild stress stimulation at the age of 11-14 weeks. Then these 30 ovariectomized rats were randomly divided into 3 intervention groups,including an energy saving light group,an incandescent light group and a circadian light group,with 10 rats in each group. The rats in these 3 groups were given specific experimental light intervention for 3 weeks respectively at the age of 17 weeks. The other 10 rats were raised in conventional environment as the control group. Their body weights were measured at the age of 17,19,20 and 21 weeks. The ethology tests were carried out by sucrose preference test and the open-field test at the age of 7,14 and 20 weeks respectively. The melatonin levels in peripheral blood of 7 time points from 19: 30 to 8: 30 were measured in the rats at age of 21 weeks. One rat in each group at every time point was randomly selected for examination. RESULTS: At the age of 17 weeks before light-intervention,the body weights of rats in 4 groups showed no significant difference( P > 0. 05). After light-intervention,at the age of 17-20 weeks,the body weights of rats in 3 intervention groups were gradually increased with the increase of age( P < 0. 05).There was no significant difference between body weights of rats at the age of 21 weeks and those at the age of 20 weeks in each group( P > 0. 05). At age of 7 weeks,no significant differences were found in sucrose consumption and standing scores among these 4 groups( P > 0. 05). After the depressive models were established,at the age of 14 weeks before light-intervention,in rats of these 3 intervention groups,the sucrose consumption and standing scores were lower than those of the control group( P < 0. 05),and there was no significant difference found in the above 2 indexes among these 3intervention groups( P > 0. 05). At the age of 20 weeks after light-intervention,the sucrose consumption and standing scores were not significantly different from each other among the 4 groups( P > 0. 05). The peak levels of melatonin in the peripheral blood of rats in these 3 intervention groups were higher than that in the control group. The peak levels onsets of melatonin in peripheral blood of rats in the circadian light group and the energy saving light group were earlier or 2 hours delayed compared to that of control group,while it was similar between the incandescent light group and control group.CONCLUSION: The circadian light,the energy saving light and the incandescent light are similarly effective in improving the behaviors of depressive rats. The circadian light can delay the onset of peak level of melatonin in peripheral blood.
