BACKGROUND: People, with various live patterns, have different impacts when walking, while the impact type always takes effects on shock attenuation of people. Foreign researches had shown shock attenuation during walking had been linked to many kinds of injuries.OBJECTIVE: This study aimed to examine whether dancers with different dancing patterns would show different impact shock attenuation when walking.DESIGN: A controlled observation.SETTING: Sports College, Guangxi Normal University; College of Human Movement Science, Beijing Sports University.PARTICIPANTS: Fourteen old social dancing exercisers who had 3 years of dancing exercises and exercised 1.0-2.0 hours per day were selected from family members' area of Beijing Sports University and recruited for this study. Seven subjects dancing with smooth rises and falls were selected into one group (namely group A) by a professional social dance teacher and another seven retires dancing with abrupt rises and falls were selected into another group (namely group B). The age, body height and body mass of subjects between two groups could be comparable. METHODS: The BK4393 uni-gain miniature accelerometers (Denmark) were attached to the skin of 3 cm below the tubercle of tibia and median line of frontal bone in subjects to test their the impact acceleration during normal speed. At the same time, retires' gaits were filmed by a normal speed camera to get the kinematic variables. All variables related to shock attenuation were compared by statistical means, and the difference of shock attenuation between two groups were analyzed.MAIN OUTCOME MEASURES: Related extremity gait kinematic parameters, peak acceleration of tibia and head, and impact shock attenuation during normal walkingRESULTS: Fourteen subjects participated in the finial analysis. Group B showed significant higher values of the maximum knee angle, maximum ankle angle and total angle change of ankle joint statistically than group A (P < 0.05). There were no significant differences in impact acceleration of tibia stance phase between two groups (P > 0.05), impact acceleration of head in the group A was lower than that in the group B (P < 0.05), and shock attenuation between tibia and head was better in the group A than in the group B (P =0.007). CONCLUSION: Dancing with smooth rises and falls is beneficial to enhancing shock attenuation ability and improving ankle dorsiflexion control and the whole coordinated ability in social dancing exercises.

Objective The purpose of this study was to describe the influence of therapy compliance on prognosis of children with thalassaemia major (TM). Methods Children with TM was recruited by convenient sampling. The therapy compliance was measured by compliance index (CI) and serum ferritin (SF), The correlation between therapy compliance and incidence of complications were studied. Results Low therapy compliance existed in children with TM, 22.12% (CI) and 55.77% (SF). But no statistical difference existed in therapy compliance between boys and girls (P>0.05). Complication incidence in children with low therapy compliance was 85.19% (CI) and 100.00% (SF). The incidence of cardiac complication was 60.49% (CI) and 84.78% (SF), hepatic complication was 46.91% (CI) and 76.09% (SF), infectious complication was 8.64% (CI) and 10.86% (SF), growth retardation complication was 55.56% (CI) and 67.39% (SF), anemia complication was 43.21% (CI) and 21.74% (SF). The incidence rate of complications was lower in children with better therapy compliance than those with worse therapy compliance (P<0.01). Conclusions Children with TM had low therapy compliance and high incidence rate of complications. Low therapy increased the incidence rate of complications.

In order to better understand the clinical manifestation of systemic lupus erythematosus (SLE) with intracranial hypertension syndrome (IHS), we analyzed the clinical features and treatment of a typical SLE patient with IHS. SLE is one of the most unpredictable autoimmune diseases involving multiple organ systems that is defined clinically and associated with antibodies directed against cell nuclei. IHS is an uncommon manifestation of neuropsychiatric SLE (NPSLE) and is characterized by an elevated intracranial pressure, papilledema, and headache with occasional abducens nerve paresis, absence of a space-occupying lesion or ventricular enlargement, and normal cerebrospinal fluid chemical and hematological constituents. IHS has been reported in a few sporadic cases in patients with SLE worldwide, but rarely has been reported in China. In this study, a 34-year-old female SLE patient with IHS was reported and pertinent literature reviewed. The clinical presentation, image logical features, and investigatory findings were discussed.

Objective:
This study aimed to investigate the impact of polycystic ovary syndrome (PCOS) on fertility-sparing treatment in young patients with atypical endometrial hyperplasia (AEH) or endometrioid endometrial cancer (EEC).
Methods:
A total of 285 patients with EEC (n=76, FIGO stage IA, without myometrium invasion) or AEH (n=209) who received progestin-based fertility-sparing treatment were evaluated retrospectively. Among the 285 patients, 103 (36.1%), including 70 AEH cases and 33 EEC cases, were diagnosed with PCOS. General characteristics, cumulative 16- and 32-week complete response (CR) rate, pregnancy outcome and recurrence were compared between patients with or without PCOS.
Results:
The cumulative 16-week CR rate was lower in the PCOS group than in the non-PCOS group (18.4% vs. 33.8%, p=0.006). Patients with PCOS took longer treatment duration to achieve CR (7.0 months vs. 5.4 months, p=0.006) and shorter time to relapse after CR (9.6 months vs. 17.6 months, p=0.040) compared with non-PCOS group. After adjusting for patient age, body mass index, PCOS, homeostasis model assessment-insulin resistance index, and serum testosterone levels, we found that body mass index ≥25 kg/m2 (HR=0.583; 95% CI=0.365–0.932; p=0.024) and PCOS (HR=0.545; 95% CI=0.324–0.917; p=0.022) were significantly correlated with lower 16-week CR rate.
Conclusion
PCOS was associated with lower 16-week CR rate, longer treatment duration and shorter recurrence interval in patients with AEH or EEC receiving fertility-preserving treatment.

BACKGROUNDPatellofemoral osteoarthritis commonly occurs in older people, often resulting in anterior knee pain and severely reduced quality of life. The aim was to examine the effectiveness of arthroscopic patelloplasty and circumpatellar denervation for the treatment of patellofemoral osteoarthritis (PFOA).
METHODSA total of 156 PFOA patients (62 males, 94 females; ages 45-81 years, mean 66 years) treated in our department between September 2012 and March 2013 were involved in this study. Clinical manifestations included recurrent swelling and pain in the knee joint and aggravated pain upon ascending/descending stairs, squatting down, or standing up. PFOA was treated with arthroscopic patelloplasty and circumpatellar denervation. The therapeutic effects before and after surgery were statistically evaluated using Lysholm and Kujala scores. The therapeutic effects were graded by classification of the degree of cartilage defect.
RESULTSA total of 149 cases were successfully followed up for 14.8 months, on average. The incisions healed well, and no complications occurred. After surgery, the average Lysholm score improved from 73.29 to 80.93, and the average Kujala score improved from 68.34 to 76.48. This procedure was highly effective for patients with cartilage defects I-III but not for patients with cartilage defect IV.
CONCLUSIONSFor PFOA patients, this procedure is effective for significantly relieving anterior knee pain, improving knee joint function and quality of life, and deferring arthritic progression.
