Objective To explore the effect of ankle strategy stability limit training on balance and gait in recovering stroke patients with hemiplegia. Methods Forty recovering stroke patients were randomized into an intervention group and a control group.The patients in the intervention group were given ankle strategy stability limit training using visual feedback on the static long sets of a Smart Equitest Balance Master (SEBM) machine.Those in the control group practiced routine postural balance training using mirror visual feedback in parallel bars.Both groups of patients practiced balance and posture control for 30 minutes,once daily,6 days a week for two weeks. Both groups were also given routine therapy and other rehabilitation.The patients' balance function was evaluated using the Berg Balance Scale (BBS),and their gait was assessed using the walk across technique (WA). Results There was no significant difference between the two groups with regard to general information,BBS scores or WA results before treatment.After 2 weeks of treatment,BBS scores as well as the step length and pace in the WA improved significantly in both groups,but all improved significantly more in the intervention group.There was no significant difference in width of gait. Conclusion Ankle strategy stability limit training can enhance weight-bearing on stroke patients' affected foot as well as their balance and the symmetry of their steps.

Objective To evaluate the therapeutic efficacy of intratympanic dexamethasone injections combined with prednisone in patients with idiopathic sudden sensorineural hearing loss. Methods A total of 71 patients diagnosed with sudden hearing loss were treated with intratympanic dexamethasone injections plus prednisone (B group) or prednisone alone (A group). Hearing was evaluated by pure tone audiogram performed before initial treatment and at 4 weeks following the final treatment. Results The total recovery rate after the treatment was 81.8% in the B group and 55.3% in the A group. The diflference between two groups was statistically significant (P < 0.05). Conclusion The present study suggests that sudden sensorineural hearing loss patients treated with intratympanic dexamethasone combined with prednisone have a higher likelihood of hearing recovery than those treated with prednisone alone.

Objective To explore the effects of sensory system obstacle on balance ability of patients with hemiplegia after stroke. Methods20 patients with hemiplegia after stroke (experimental group) and 20 normal people (control group) received Sensory Organization Test(SOT) with Smart Equitest Balance Master system. The balance index and the sensory index were accessed. Results The scores of the balanceindex in the experimental group were lower than in the control group in EC, SV, EOSS, ECSS, SVSS (P<0.05). The scores of somatosensory,visual and vestibular indexes in the experimental group were lower than in the control group (P<0.05), especially for vestibular index.Conclusion The sensory loss caused the balance dysfunction in patients with stroke.

Objective To observe the effect of electrical stimulation of the pelvic floor muscles (PES) combined with acupuncture on urinary dysfunction in patients with spinal cord injury (SCI). Methods Sixty-two patients with SCI were randomly divided into a treatment group ( n =31 ) and a control group ( n =31 ).All subjects received routine bladder function training and a drinking water schedule for 8 weeks.In addition,the treatment group was given PES 30-40 min/d 6 times/week and acupuncture for 30 min/d,6 times/week for the 8 weeks.Residual volume of urine was evaluated using ultrasound and a daily voiding diary.Uurodynamic examinations and catheter extraction were used to assess the urinary function pre- and post-treatment. Results No significant difference was found between the two groups before treatment,but after 8 weeks of treatment the residual volume of urine detected by ultrasound and voiding frequency were significantly lower in the treatment group than in the control group.First desire to urinate and maximal urinary bladder capacities in the treatment group were also significant higher than in the control group.The efficacy of treatment was also sustained significantly longer in the treatment group. Conclusion PES combined with acupuncture therapy is more effective than routine bladder function training for SCI patients with urinary dysfunction.

Objective To evaluate the long-term efficacy of recombinant human endostatin (rh-Endo) combined with FOLFOX4 as an adjuvant treatment for patients of stage Ⅱ and Ⅲ colorectal cancer.Methods Eligible patients were randomly assigned to receive FOLFOX4 or FOLFOX4 plus rh-Endo regimen in which patients receiving 7.5 mg/m2 Ⅳ on day 1-7,repeated every 2 weeks,to a total of 12 cycles in 6 months.Results A total of 197 eligible patients were accrued in this research with 105 patients in the control group and 92 patients in the experimental arm.Median follow-up period was 42 months.The baseline characteristics distributed were balanced by treatment.Rh-Endo combined with FOLFOX4 regimen resulted in significant improvement on DFS compared to FOLFOX4 regimen for patients with stage Ⅲ colon cancer (HR =0.19,95％ CI0.05-0.75,P =0.0124),and with a 34％ improvement on 3-year DFS and 81％ reduced recurrence.Although rh-Endo combined with FOLFOX4 regimen failed to make significant difference on DFS in the whole (HR =0.75,95％ CI 0.31-1.83,P =0.5589),it was also observed a 17％ improveiment on 3-year DFS.No statistical significant difference on DFS was observed in patients with stage Ⅱ disease.Conclusions Rh-Endo combined with FOLFOX4 regimen significantly improved the disease-free survival for patients with stage Ⅲ colorectal cancer,indicating that patients with stage Ⅲ disease,but not stage Ⅱ disease,can benefit from FOLFOX4 plus rh-Endo regimen in adjuvant treatment.

Objective As we know more about CVA and examination methods are becoming more popular,the number of patients diagnosed as CVA is increasing year after year.So it is necessary that we should find more clinical characteristic and therapy for CVA.Methods 155 CVA patients have been observed for 2 years and the results of bronchial methacholine chloride provocation test before and after the observation were analyzed.Results 30% of the patients werent analyzed because they did not take the drugs regularly.The result showed that the CVA male vs female was 1 ∶4,the average age was(40?7.2)years.20 patients developed typical asthma(12.94%).After 2 years,70% of the patients had positive results of the bronchial methacholine chloride provocation.Methacholine chloride concentration was negatively related to hyperresponsiveness of bronchus.FEV_1% was negatively related to the state of asthmatic degree.Conclusions The CVA was incident to the young and the middle-age females,often with an obvious inducement.The female prognosis was worse than that of the male.Generally speaking,the prognosis was good if patients took medicine regularly.Patientscompliance was the essence of the prevention and the cure.Young females who had chronic cough indicate CVA.The concentration of methacholine chloride and FEV_1% were effective indexes when we estimated the state and prognosis of CVA.In most CVA patients,the hyperresponsiveness stayed for a long time,which may be one of the most dangerous risks.We should keep on observing and treating those patients.

Objective:To investigate the neuroimaging relationship between tau protein deposition and brain atrophy, and assess their relationships with cognitive decline in Alzheimer′s disease (AD) patients.Methods:From April 2017 to October 2019, 26 AD patients (12 males, 14 females, age (70.7±12.2) years) and 19 cognitively normal controls (CN; 9 males, 10 females, age (65.6±8.1) years) in Chinese PLA General Hospital were retrospectively enrolled. All subjects received (S)-6-[(3- 18F-fluoro-2-hydroxy)propoxy]-2-(4-methylaminophenyl)quinoline ( 18F-THK5317) PET/MR and the standardized uptake value ratio (SUVR) and gray matter volume (GMV) were measured. General linear model (GLM) was used to evaluate the differences of SUVR and GMV between two groups. Pearson correlation analysis was used to assess the relationships between SUVR and GMV, and relationships of SUVR and GMV with Mini-Mental State Examination (MMSE) scores in AD patients. Results:Compared with CN, the AD patients showed significantly increased 18F-THK5317 retention in lateral temporal, frontal, posterior cingulated/precuneus and occipital cortex with significant differences of SUVR between two groups (2.18±0.54 vs 1.78±0.09, 2.13±0.50 vs 1.82±0.06, 2.03±0.45 vs 1.69±0.08, 2.18±0.57 vs 1.76±0.10, t values: 2.58-6.57, all P<0.001). The AD patients also showed decreased GMV in medial temporal, posterior cingulated/precuneus and orbitofrontal cortex ( t values: 3.67-8.85, all P<0.001). In AD patients, SUVR was negatively associated with GMV in bilateral lateral temporal cortex, pre-frontal cortex and orbital frontal cortex ( r values: from -0.52 to -0.43, all P<0.05). Both SUVR ( r=-0.599, P=0.001) and GMV ( r=0.443, P=0.023) were significantly correlated with MMSE scores in AD patients. Conclusion:AD patients have neocortical 18F-THK5317 abnormal uptake and GMV reduction, which are significantly correlated with cognitive decline.

Objective To investigate the clinical manifestations, pathologic features, treatment and prognosis of oncogenic osteomalacia (OO). Methods A 17-year-old male patient was admitted.The patient presented with a 4-year history of progressive lower limb weakness, muscle atrophy and joint pain. Lab tests demonstrated hypophosphatemia. Lumbar and pelvic X-ray showed wedging of the lumbar spine and decreased pelvic bone density. Ultrasonography revealed a low-echo and bloodrich mass measuring 15.1 cm× 14.5 cm× 13.2 cm located at the lower pole of left kidney. Computed tomography showed a voluminous enhanced tumor, supplied by the left renal artery, vice renal artery and a branch of the inferior mesenteric artery. A tortuous vein at the lower part of the tumor drained into the left renal vein. A radioactive octreotide scan was used to study an increased radionuclide-uptake lesion which was initially suspected on the CT scan. The patient was preoperatively diagnosed with left malignant kidney tumor and oncogenic osteomalacia. During a left radical nephrectomy performed through a transperitoneal anterior subcostal incision, a round diameter 15 cm tumor covered by twisted veins was found. The patient recovered well postoperatively. Results The histological diagnosis was renal clear cell carcinoma. Immunohistochemical staining detected Vimentin and RCC were positive and Ki-67antigen index was about 2 %. After lesion removal, the paraneoplastic syndrome resolved. At the 11-month follow-up, no recurrence of the disease was observed. Conclusions Oncogenic osteomalacia is rare and OO with renal cell carcinoma has not been reported so far. OO or rickets should be suspected in those patients who presented with metabolic bone disease associated with hypophosphatemia and inappropriate phosphaturia. If OO syndrome was suspected, in addition to past medical history and imaging, a standard meticulous examination should be initiated promptly. Surgical treatment is still necessary once confirmed. And all of them achieved a good prognosis.
