A device for promoting normal locomotor activity recuperation was made, which was composed by frame, elastic bolt and normal gait mark carpet. The device has the effects of weight relieving, abnormal gait preventing, and safeguards providing. The patient could do gait training by he/her self or assistant self training under the weight reducing and protecting of the device in order to improve the walking ability and the normal gait formation. It is effective for preventing drop foot and leg adduction, and also helpful for the recovery of normal gait ability and the prevention of abnormal gait formation. It is applicable for the patient who can not be trained with ordinary weight relief walking training, such as severe cerebral palsy and severe spasmodic lower extremity and foot drop after brain injury. The results demonstrated that the device is effective in protecting, correcting, preventing abnormal gait as well as forming normal gait.

OBJECTIVETo observe the inhibitory effect of citrus extract nobiletin on K562 cells xenograft in nude mice and discuss its anticancer activity and mechanism.
METHODThe model of K562 cells xenograft was established in nude mice. Twenty-five nude mice were divided to five groups. After 24 hrs of inoculation with K562 tumor cells subcutaneously, 1% CMC-Na in the nude mice of model control group, nobiletin (12.5, 25, 50 mg x kg(-1)) in the nude mice of nobiletin groups and CTX (20 mg x kg(-1)) in positive control group were administered once every day. The nude mice were killed at 18th day-point of administration. The inhibitory rate of nobiletin on tumor was calculated according to the measured tumor weight. Immunohistochemistry assay was used to determine the effect of nobiletin on VEGF expression and MVD, and CAM assay was used to detect the effect of nobiletin on vessel regeneration.
RESULTNobiletin have notable inhibition on K562 cells xenograft in nude mice comparing with model control group (P < 0.01), the inhibitory rate of nobiletin groups were 36% -58%. The results of immunohistochemical technology showed that the expression of VEGF in nobiletin groups decreased significantly comparing with the model control group (P < 0.05, P < 0.01, P < 0.01). Nobiletin could remarkably decrease the angiogenesis within tumor tissues. The expression of CD34 in nobiletin low dose group and high dose group was lower than that in model control group (P < 0.05, P < 0.01). The result of CAM indicated that 4 microg and 2 microg nobiletin could inhibit the new blood vessels of CAM (P < 0.01).
CONCLUSIONNobiletin inhibited the tumor growth and angiogenesis by reducing the VEGF expression of K562 cells xenograft in nude mice.

Objective:To retrospectively analyze the treatment of 25 cases of lower necrotizing fasciitis.Methods:A total of 25 patients with lower limb necrotizing fasciitis (13 males and 12 females), with mean age 63 years old (48-75 years old) in Dalian Municipal Central Hospital from September 2016 to December 2020. After admission, the patient′s general physical condition was strictly evaluated, the relevant preoperative examination was improved, and the necrotizing fasciitis laboratory risk index (LRINEC) score was performed. In the absence of surgical contraindication, multiple debridement was performed, leaving the necrotic tissue removed for general bacterial culture and drug sensitivity test in parallel. After debridement, eight patients showed a large area of skin necrosis, and amputation was selected. The other 17 patients chose limb protection treatment after debridement, and adopted debridement and free skin grafting. After surgery, patients were encouraged to strengthen rehabilitation exercise to restore limb function to the maximum extent.Results:With followed up 0.6 to 3.0 years, with an average of 1.8 years. Methods include outpatient return visit, WeChat contact or telephone inquiry. The skin survived in 17 patients with mean healing time (27.5 ± 6.9) d. Eighteen patients were multiple bacterial infections and seven patients were single bacterial infections. All patients had no joint dysfunction caused by scar contracture, and reinfection in the skin grafting area.Conclusions:Necrotizing fasciitis requires early diagnosis and early treatment, with correct choice of treatment method is closely related to the patient′s prognosis.
9.Correlation analysis of takeaway food consumption and sleep disturbance among college students in Jiangxi Province
Chinese Journal of School Health 2021;42(10):1530-1535
Objective:
To investigate the correlation between takeaway food consumption and poor sleep status of college students in Jiangxi Province, to provide a theoretical basis for poor sleep prevention and intervention among college students.
Methods:
A total of 2 610 college students were selected from a university in Shangrao City, Jiangxi Province by cluster stratified random sampling in May of 2018. The frequency and type of takeaway food consumption, sleep quality and drowsiness were investigated.
Results:
The detection rate of takeaway food consumption behavior(≥4 times in a week) for college students was 74.8%. The detection rates of poor sleep quality and drowsiness were 17.0% and 18.3%, respectively. The difference of sleep quality was statistically significant with sex, college, different self rated family conditions, study burden, physical activity level, depression and daily smoking ( χ 2=4.33,8.67,23.14,39.03,12.89,313.37,15.23, P <0.05). There were statistically significant differences between drowsiness and college, grade, learning burden, physical activity and depression ( χ 2=12.81,6.57,20.61,8.42,228.06, P <0.05). Logistic regression analysis showed that takeaway consumption (≥4 times in a week) had statistical significance with poor sleep quality and drowsiness ( P <0.05).
Conclusion
College students takeaway consumption (≥4 times in a week) of rice noodles, malatang, fragrant pot hot pot increase the risk of poor sleep. It is suggested that schools should strengthen nutrition and health education for college students.
