Objective To detect and analyze thyroid tumor by two-dimensional sonogram and Doppler parameter, and evaluate the value of high-frequency ultrasound in diagnosing thyroid benign and malignant tumors. Methods The ultrasonic images of 104 thyroid tumor from 80 patients with typical features were collected. Thyroid tumor was classified into benign and malignant nodules, based on the shape, border, or the rear wall echo, echo attenuation loss, internal echo, and microcalcifications in two-dimensional sonogram and systolic blood peak velocity (Vmax) and resistant index (RI) in Doppler examination. The expected results of high frequency ultrasound were compared with pathological results on consistency and error rate. Results Prediction of benign tumor by high frequency ultrasound was 66, and pathology 61, consistency rate of the two was 92.4%. Prediction of malignant lesions was 38, and pathological examination 32, consistency rate of the two was 84.2%. The total coincidence rate was 89.4%(93/104) and the error rate was 11.6%( 11/104). Conclusions The typical features of thyroid tumor on high-frequency ultrasound are helpful in diagnosis of benign or malignant nodules, which is valuable in guiding clinical treatment.

The infant (a girl aged 6 months) was admitted to the hospital because of oliguria and acute renal dysfunction. The laboratory examination results showed serious metabolic acidosis and increased blood urea nitrogen and serum creatinine levels. The patient continued to be anuric after 10 days of treatment with continuous renal replacement therapy (CRRT). she died a day later. The family history showed that the patient's sister died of acute renal failure 6 months after birth. The genomic sequencing results showed AGXT mutation in the patient and confirmed the diagnosis of primary hyperoxaluria type 1 (PH1). Her parents were heterozygous carriers. PH1 should be considered when the children have abnormal renal function or recurrent renal calculi or have a family history of these symptoms. AGXT gene analysis is an important method for PH1 diagnosis.

A boy aged 11 years was admitted due to intermittent weakness and difficulty in walking for 6 years, and hepatomegaly, glycopenia and unconsciousness for 4 years. The laboratory examinations showed severe metabolic acidosis, hypoglycemia, and abnormal liver function. CT scan showed marked liver enlargement with fat density shadow. The boy was given fluid infusion, correction of acidosis, intravenous injection of glucose, L-carnitine, compound vitamin B, and coenzyme Q10, but he was in a persistent coma and it was difficult to correct refractory metabolic acidosis and hypoglycemia. The boy died. Blood and urinary organic acid screening and gene detection confirmed that the boy had late-onset glutaric aciduria type II (GAIIc) caused by electron-transferring-flavoprotein dehydrogenase (ETFDH) gene defect. GAIIc is an inherited metabolic disease with a low incidence, resulting in a high misdiagnosis rate. GAIIc should be considered for children with recurrent weakness or reduced activity endurance, hypoglycemia, and marked liver enlargement with abnormal liver function. Urinary organic acid analysis and blood tandem mass spectrometry can help with the early diagnosis of GAIIc, and ETFDH gene analysis helps to make a confirmed diagnosis.

BACKGROUND: Acupuncture is a common treatment for urinary retention after spinal cord injury. It has been widely used in the clinical treatment of urinary retention after spinal cord injury due to its small side effects and simple operation. However, there is a lack of evidence-based medicine. OBJECTIVE: To examine the effectiveness of acupuncture for urinary retention in patients with spinal cord injury by a systematic review and Meta-analysis of randomized controlled trials (RCTs). METHODS: A computer-based online retrieval of CBM, CNKI, WanFang, Cochrane Library, PubMed, EMBASE, and Web of Science databases was performed. The keywords were "spinal cord injury, neurogenic bladder, acupuncture" in English and Chinese, respectively. RCTs concerning acupuncture or acupuncture combined with conventional therapy were identified and a Meta-analysis was conducted on RevMan 5.3 software. RESULTS AND CONCLUSION: Nine RCTs involving 632 participants were included. In terms of urodynamic changes, compared with the control group,acupuncture was more effective in improving the residual urine volume[mean difference(MD)=-144.26,95% confidence interval(CI)(-252.15,-36.37),P=0.009]and maximum cystometric capacity[MD=35.69,95%CI(3.15,68.22),P=0.03].However,there were no significant differences between two groups for average daily number of urination[MD=-1.66,95% CI(-3.40,0.07),P=0.06].Concerning total effective rate,acupuncture was more effective than control group[RR=1.24,95%CI(1.11,1.37),P<0.0001].To conclude,compared with the conventional therapy, acupuncture is more effective in improving residual urine volume, maximum cystometric capacity and total effective rate for urinary retention in patients with spinal cord injury.

Objective To observe the effects of standardized three stage rehabilitation treatment on the neu- rological deficit scores (NDS) and ADL performance of ischemic stroke patients.Methods A total of 164 ischemic stroke patients were recruited and randomly divided into a rehabilitation group and a control group.The neurological function and ADL performance of the patients were assessed by using NDS and Modified Barthcl Index (MBI) at the admission,at the end of 1st,3rd and 6th months post stroke.Results No significant differences were found be- tween the rehabilitative and the control groups with regard to NDS and MBI at admission.The NDS demonstrated a decreasing tendency,while the MBI score an increasing tendency in both groups.In the control group,significant difference of NDS was found between admission and the end of 1st month as well as between the end of the 1 st and the 3rd months.In rehabilitation group,significant difference was revealed between all the time points with regard to NDS and MBI scores.At the end of the 1st,3rd and 6th months,the MBI scores of the rehabilitation group were signifi- cantly higher than those of the control group,indicating that the ADL performance of those treated with standardized three-stage rehabilitation protocol was improved quicker than those without the protocol.Conclusion Standardized three-stage rehabilitation treatment could improve the neurological function and ADL performance of the ischemic stroke patients.
