RESUMO
OBJECTIVE@#To compare the effect of acupoint injection and intramuscular injection with mouse nerve growth factor (mNGF) on gross motor function development of children with cerebral palsy (CP), and explore the treatment mechanism.@*METHODS@#A total of 63 children with CP were randomly divided into an observation group (32 cases, 4 cases dropped off ) and a control group (31 cases, 3 cases dropped off). Based on the routine rehabilitation therapy, the control group received intramuscular injection of mNGF(18 µg/2 mL), and the observation group received acupoint injection of mNGF at Xinshu (BL 15), Ganshu (BL 18), Pishu (BL 20), Shenshu (BL 23), Sanjiaoshu (BL 22), Shenting (GV 24), Baihui (GV 20), Fengfu (GV 16), Dazhui (GV 14), etc. Of them, 5-6 acupoints alternately were selected each time, and each acupoint was given 0.3-0.5 mL, totally 18 µg/2 mL. Both treatment were carried out once every other day for six months. Before and after treatment, the children's development of brain function was assessed using gross motor function classification system (GMFCS). Before treatment (T), after 2 (T), 4 (T) and 6 (T) months of treatment, the motor function was evaluated by gross motor function measure (GMFM-88). The systolic peak velocity (Vs), mean velocity (Vm) and vascular resistance index (RI) of anterior cerebral artery (ACA) and middle cerebral artery (MCA) were measured, and the level of N-acetyl aspartate acid (NAA), choline (Cho), lactate (Lac) and creatine (Cr) from the basal ganglia, thalamus and periventricular white mater were detected by magnetic resonance spectroscopy (MRS) technology with MAGNETOM Skyra3.0T magnetic resonance imaging system before and after treatment.@*RESULTS@#Compared with before treatment, the GMFCS classification of the observation group after treatment was significantly improved (0.05), however, the observation group had a 3.142 times of feasibility for good gross motor function development by more than level 1 compared to the control group (<0.05). After 2, 4, and 6 months of treatment, the GMFM-88 scores of the two groups showed an upward trend (<0.01), and the increase of the observation group was greater than that of the control group (<0.05). Compared with before treatment, in the ACA and MCA, the Vs and Vm increased, RI decreased in both groups after treatment (<0.01), and in the brain, NAA/Cr increased, Cho/Cr and Lac/Cr decreased (<0.01), and after treatment, the Vs, Vm of ACA and MCA and NAA/Cr of brain in the observation group were higher than those in the control group (<0.05), and the RI of ACA and MCA and Cho/Cr and Lac/Cr of brain in the observation group were lower than those in the control group (<0.05).@*CONCLUSION@#The mNGF acupoint injection has a better effect on the gross motor function in the children with cerebral palsy compared with the intramuscular injection, and the mechanism may be associated with exhibiting the double effects of acupoint effect and the targeting therapy of drug, which can effectively improve the cerebral hemodynamics and the metabolism of cerebral nervous substances.
RESUMO
Objective:This study investigates the significance of human papilloma virus (HPV) subtype detection in opportunis-tic screening for cervical cancer in Uygur and Han women. Methods:Flow-through hybridization gene chip and thin-prep cytology test were used to detect HPV in cervical cell samples from 1140 females. A total of 428 patients had undergone cervical biopsies through colposcopy. The diagnostic results of the HPV subtype test for cervical lesions were evaluated on the basis of histology. Results:Total HPV infection rate for the 1140 cervical samples was 30.3%. The most common HPV subtypes were HPV16, HPV58, HPV52, HPV18, and HPV45. HPV52 infection rate was higher in Han women than in Uygur women, with statistically significant differences between the two (χ2=8.737, P=0.003). Among these cervical samples, the single HPV infection rate was 22.4%(255/1140), whereas the multiple HPV infection rate was 6.1% (69/1140). The sensitivity and specificity of the HPV subtype test for cervical lesions were 86.4% and 24.5%, respectively. The positive and negative predictive values were 58.5%and 59.3%. Conclusion:HPV infection subtypes in Ugyur and Han women have unique characteristics. Subtype detection is important in opportunistic screening for cervical cancer.
