Objective To evaluate the effects of post-operation rehabilitation treatment of patients with calcaneus fracture by dynamic plantar pressure analysis,and assess the value of the Footscan system.Methods Sixty-two patients with unilateral calcaneus fracture were randomly divided into a rehabilitation group and a control group.The patients in the rehabilitation group were given early,systemic standard rehabilitation treatment,while those in the control group took functional exercise following the doctors'advice.At 3 months and 6 months after operation,the plantar pressure distribution of the patients in both groups was analyzed with the Footscan system,respectively.Results After 3 months of treatment.there was statistically significant difference between the injured and the uninjured sides in both groups,with regard to the contact time,average plantar pressure and pressure-time integrals at different phases of gait.However,there was no significant difference between the injured and the uninjured sides after 6 months in rehabilitation group.But in control group,there was still statistically significant difference between the two sides with regard to the above parameters.Conclusion Early rehabilitation treatment could significantly improve the function outcome of patients with calcaneus fracture.Footscan System can objectively evaluate the recovery of the calcaneous fracture.

BACKGROUND:Studies have reported that taurine has a certain therapeutic effect on the disease of various systems, such as nervous system, cardiovascular system, immune system and digestive system. The liver is the main place, also the important target organ, of taurine metabolism. Therefore, the relationship between taurine and hepatopathy has become a hot topic in recent years. OBJECTIVE:To investigate the influence of taurine on superoxide dismutase and malondialdehyde expression in the liver tissue of rat models of liver fibrosis induced by carbon tetrachloride. METHODS:Thirty male C57B/L rats of SPF grade were randomly and evenly divided into blank control, model and taurine groups. Rats in the blank control group were intraperitonealy injected with 100% peanut oil of 1 mL/kg, twice a week, in total 10 weeks. Rats in the model group were intraperitonealy injected with peanut oil of 1 mL/kg containing 20% carbon tetrachloride, twice a week, in total 10 weeks. Rats in the taurine group were intraperitonealy injected with peanut oil of 1mL/kg containing 20% carbon tetrachloride, twice a week, in total 10 weeks, and were intragastricaly administered taurine of 500 mg/kg per day starting from the 3rd week til the 10th week. RESULTS AND CONCLUSION:Compared with the blank control group, the serum levels of hyaluronic acid, laminin, typeⅢ procolagen, typeⅣ colagen, alanine aminotransferase, aspartate aminotransferase were significantly increased (P < 0.05), the level of superoxide dismutase in the liver tissue was lowered (P < 0.05), the level of malondialdehyde in liver tissue was significantly increased (P < 0.05), and liver index was increased (P < 0.05) in the model group. Pathological examination showed that there were necrosis of liver cels, fat vacuoles, fibrous tissue hyperplasia and inflammatory cel infiltration in the rats of the model group. Compared with the model group, the serum levels of hyaluronic acid, laminin, typeⅢ procolagen, typeⅣ colagen, alanine aminotransferase, aspartate aminotransferase were significantly lowered (P < 0.05), the level of superoxide dismutase in the liver tissue was significantly increased (P < 0.05), the level of malondialdehyde in the liver tissue was significantly lowered (P < 0.05), and liver index was significantly decreased (P < 0.05) in the taurine group. Pathological examination showed that there were no inflammatory cel infiltration, fat vacuoles, and fibrous tissue deposition in the liver tissue. The results indicate that taurine can decrease the contents of superoxide dismutase and malondialdehyde, and relieve the degree of liver fibrosis induced by carbon tetrachloridevia exerting its antioxidative effects.

Objective. To study the performance of free nerve graft with vascular implantation.Material and method. Three groups of rats were used. A 10 mm nerve defect was made in the sciatic nerve. It was repaired respectively with vascularised nerve graft(VNG), free nerve graft with vascular implantation(NGV) or free nerve graft(NG). Before 30 days the revascularisation of the nerve graft was assessed;at 2 to 3 month regeneration of nerve was evaluated. Histochemical staining, vascular morphology and electrophysiological examination were undertaken.Result and conclusion. The number of regenerated blood vessels in VNG and NGV was significantly increased than that in NG before 30 days. The ratio of regenerated nerve fiber area and conduction velocity in the first two groups were much better than those in NG at 2 to 3 months.

Objective To explore the correlation between TCM constitution and sleep status in escort troops. Methods Standardized TCM Constitution Questionnaire and Pittsburgh Sleep Quality Index (PSQI) were used to investigate escort troops. Factors of PSQI and constitution types were analyzed. Results The results of PSQI showed the number of escort troops who had bad sleeping (PSQI>7) was 64, which accounted for 46%of the escort troops, among which, 45 people (70.3%) were justified as biased constitution, while 19 were normal constitution (29.7%). The top three biased constitution in bad sleeping were:qi deficiency, phlegm-dampness and dampness-heat. PSQI factors such as sleep disorder, daytime dysfunction and total score had positive correlation with qi deficiency, yang deficiency, yin deficiency, dampness-heat and blood stasis, and negative correlation with normal constitution. Conclusion Sleep condition of escort troops has correlation with TCM constitution, which indicates that sleep status could be improved by regulating TCM constitution.

Objective: To evaluate the application of real-time RT-PCR and semi-nested RT-PCR in the detection of norovirus in oysters and analyzing the genetic characteristics of the isolates. Methods: Real-time fluorescent RT-PCR and semi-nested RT-PCR were used to detect norovirus GⅠ/GⅡ in fresh oysters collected from the markets in Beijing from November 2014 to October 2015. The detection rate of the parallel test was also analyzed. In addition, the reliability of semi-nested RT-PCR was evaluated by agreement rate and consistency test (Kappa value). The positive products of norovirus GⅠ/GⅡ capsid protein region gene by semi-nested RT-PCR were sequenced. Software BioEdit 7.0.9.0 was used for sequence alignment, and software Mega 6.0 was used to construct the evolutionary tree. Results: In 72 samples, the detection rate of norovirus was 31.94% (23/72) by real-time RT-PCR, 38.89% (28/72) by semi-nested RT-PCR and 48.61% (35/72) by parallel test. The coincidence rate of the two methods was 73.61%, a moderate degree (Kappa value =0.43). A total of 13 norovirus strains were successfully sequenced, and 11 strains (7 GⅡ.17 strains, 2 GⅡ. 4 Sydney_ 2012 strains, 1 GⅡ. 1 strain and 1 GⅡ. 21 strain) were obtained from norovirus positive samples by two RT-PCR methods, two strains (1 GⅡ. 17 strain and 1 GⅡ. 3 strain) were obtained from real-time RT-PCR negative samples which were positive for norovirus by semi-nested RT-PCR. The similarity between these strains and reference strains from diarrhea patients, environmental sewage, and shellfish products were 84.4% - 100.0%. Conclusions: The parallel test of norovirus in oysters by two RT-PCR methods can improve the detection rate and detect more genotypes. Norovirus strains in oysters were highly homologous with reference strains from diarrheal patients, environmental sewage, and shellfish products. Therefore, surveillance, prevention and control for norovirus should be carried out in people who have frequent contacts with oysters and related environments.
