The foot overpronation is termed as pronation persisting more than 25%of stance phase in a walking cycle, which may re-sult from some antenatal or postnatal conditions. Overpronation would lead to abnormal alignment of ankle, knee, pelvis and spine, and re-sult in a set of syndromes of chronic pain. The Navicular Drop Test and the Foot Posture Index are often used as the assessment tools, how-ever, there are several empirical ways for clinic. Foot orthoses, special shoes, taping and training of muscle strength are effective on overpro-nation as well as chronic pain.

BACKGROUND:Implant stability is the basic requirement of osseointegration and also one of important parameters to judge whether the implant is implanted successfully. Generaly, the implant stability is closed related to bone quality (bone hardness and bone density) in the implant zone, implant shape, diameter and length. OBJECTIVE:To continuously monitor the changing trend of implant stability during early healing period due to the utilization of osteotome technique by resonance frequency analysis. METHODS:Twenty patients with class Ⅳ defects in the posterior maxila who underwent implant restoration (4.8 mm×12 mm) from 2010 to 2011 at the Department of Stomatology, the 521 Hospital of China North Industries Group Corporation were recruited. Resonance frequency analysis was used to measure the implant stability at implant insertion, 1, 2, 3, 4, 6, 8 and 12 weeks postoperatively. RESULTS AND CONCLUSION:Al the implants achieved osseintegration uneventfuly within 12 weeks. At implant instalation, the mean implant stability quotient value was 69.66±4.75. An increase trend in implant stability quotient values was visible within 1 week, and the implant stability quotient value reached the peaked at 1 week, and then decreased to the lowest point at 2 weeks, which were significantly different from that at implant instalation (P < 0.05). In the secondary stability phase, the increasing slope of implant stability quotient values reached a plateau by the 8th week. The resonance frequency analysis can estimate the quantitative change of implant stability after applying the osteotome technique, and the osteotome technique can promote the implant initial stability.

Objective To systematically review the evaluation tools for walking ability of lower limb amputees wearing prostheses. Methods A computer-based search of PubMed, Wanfang Data and CNKI.net was performed for articles related to the evaluation of walking ability of lower limb amputees wearing prostheses published from January, 1995 to December, 2015. Results and Conclusion A total of 20 papers were selected, including 18 foreign literatures and 2 Chinese articles. There were many evaluation tools for walking ability of lower limb amputees wearing prostheses, and should be chosen according to the actual situation.

Objective To investigate walking ability of amputees with unilateral transtibial prosthesis. Methods From April to Decem-ber, 2016, 20 unilateral transtibial amputees (patients) and 20 healthy adults (controls) were tested with L test, balance test, 6-minute walk test (6MWT) and 1000 m walking outdoor on various terrain. Results There was no significant difference in time of L test between the am-putees wearing Solid Ankle Cushion Heel (SACH) and Storage Foot (t=0.675, P>0.05). In balance tests, there was no significant difference in the total track length, confidence ellipse area, maximum horizontal deviation and maximum vertical deviation between the patients and the controls (t<0.803, P>0.05). Each parameter was significantly different in 6MWT between them (t>2.774, P<0.01), as well as the time and energy expenditure of outdoor 1000 m walk test (t>4.130, P<0.001). Conclusion The walking ability of the unilateral transtibial ampu-tees wearing prostheses is different from normal people. The transtibial prosthetic feet that the amputees wear may impact their walking abil-ity.

Objective To compare the curative effect of perindopril and metoprolol in the treatment of diabetic patients with asymptomatic cardiac insufficiency.Methods According to the method of random numbers, 152 diabetic patients with asymptomatic cardiac insufficiency were divided into the observation group and control group,with 76 cases in each group.The observation group was given with perindopril treatment,while control group was given with metoprolol treatment.The cardiac function index,glycosylated hemoglobin,BNP levels,the incidence of cardiac insufficiency and the occurrence of adverse drug reactions before and after treatment were compared.Results There were no significant differences in LVEF,Tei index and E/A between two groups before treatment (all P >0.05 ).Compared with before treatment,the cardiac function indexes of the two groups were significantly improved after treatment(t=5.96,4.83,4.91,10.22,5.68,5.18,all P<0.05),but the observation group were improved more significantly(t=5.64,4.67,5.03,all P<0.05).Before and after treatment,there was no significant difference in the levels of glycosylated hemoglobin(all P>0.05),and the difference between the two groups was not statistically significant(all P>0.05).The BNP levels of the observation group before and after the treatment were (515.43 ± 58.85)pg/mL and (214.43 ±32.42)pg/mL respectively,of which the control group were (513.94 ±59.11)pg/mL and (263.32 ±43.31)pg/mL respectively,and after treatment,the BNP levels of the two groups were significantly decreased(t=23.45,17.68,all P<0.05),of which the observation group decreased more obvious(t=6.97,P<0.05).The cardiac insufficiency incidence of the observation group was 3.95%,which was significantly lower than 14.47% of the control group(χ2 =5.03,P<0.05).The incidence of adverse drug reactions had no obvious differ-ences in both groups(χ2 =0.08,P>0.05).Conclusion Using perindopril in treatment of diabetic patients with asymptomatic heart function can obviously improve cardiac function,reduce the incidence of BNP and cardiac insuffi-ciency.It has the clinical curative effect and high safety.

Objective To investigate the characteristics of walking ability of the amputees with unilateral transfemoral prosthesis. Methods 16 unilateral transfemoral amputees (patients) and 16 healthy adults (controls) were tested with 6-minute walking test indoor, 1000 m walking outdoor on various terrain, balance test and energy expenditure test. Results The speed, frequency and stride length were significantly less in the patients than in the controls (P<0.05) in the indoor 6-minute walking test, and the cycle of gait and energy expenditure were significantly more (P<0.05); single support time, double and single/double support time were different (P<0.05). In balance tests, there was no significant difference in the total track length, confidence ellipse area, maximum horizontal deviation and maximum vertical deviation between the patients and the controls (P>0.05). There were significant differences in time and energy expenditure of outdoor 1000 m walk test between two groups (P<0.05). There were significant differences in time of outdoor 1000 m walk test and distance of indoor walking test between amputees wearing mechanical four-link prosthetic knee joint and fluid control prosthetic knee joint (P<0.05), but not in energy expenditure of indoor and outdoor walking test. Conclusion The amputees with unilateral transfemoral prosthesis appear the inefficient in gait, and expend more energy. Their balance remains well. The transfemoral prosthesis the amputees wore may impact their walking ability.

Objective To compare the energy expenditure of a hemicorporectomy amputee moving with different mobility devices. Methods A middle-aged male hemicorporectomy amputee was measured with cardiopulmonary exercise test when moving with 4 kinds of transport: socket, cart, wheelchair, and prosthesis. Results The patient moved the slowest with prosthesis, fastest with wheelchair. The heart rate was the highest with prosthesis and lowest with cart. The absolute oxygen consumption, the relative volume of oxygen consumption and metabolic (Mets) were the most when hand walking with socket, and lowest with cart. Conclusion Hand walking with socket costs the largest energy when walking, and the rest are prosthesis, wheelchair, and cart.

BACKGROUND:Previous research have confirmed that CD34 is closely related to oncogenesis, progress, recurrence, metastasis and drug-resistance of various cancers, but its role in nasopharyngeal carcinoma remains unclear.
OBJECTIVE:Tosortcels positive and negative for CD34 in nasopharyngealcarcinoma cel lines and to detect cel proliferation and migration.
METHODS:Expressionsof CD34 in nasopharyngeal carcinoma cel lines 5-8F, 6-10B, CNE1 and CNE2 were detected by flow cytometry. And CD34+and CD34-cels were sorted based on cel surfacemarkers for purity identification. Afterwards, proliferation and migrationof CD34+and CD34-celswere detected by MTT assay, colony-formation assay and scratch assay.
RESULTS AND CONCLUSION:Al four nasopharyngeal carcinoma cel lines expressed CD34 in
0.1%-0.2%, and the level of CD34 was closely related to the cel growth density. The purity of CD34+cel was more than 98% in the sorted CD34+celpopulations, but no CD34+cels were found inthe sorted
CD34-celpopulations.At 1, 3, 5 and 7 daystheproliferation rate of CD34+cel, populationswas
significantly higher than that of CD34-cels (P< 0.05). Consistently, thecolony-formation efficiencyof CD34+cel was significantlyhigher than that ofCD34-cels (P< 0.05). Moreover, CD34+cels migrated significantly faster than CD34-cels by scratch assay (P< 0.05). In conclusion, CD34+cels culturedin vitro display higher proliferation and migration capacities, indicating that CD34+celshavethe potential of nasopharyngeal carcinoma stem cels.
