Objective To evaluate the efficacy and toxicity of induction chemotherapy with nedaplatin and docetaxel plus concurrent intensity?modulated radiotherapy ( IMRT) with nedaplatin or cisplatin in the treatment of locally advanced nasopharyngeal carcinoma (NPC). Methods A total of 223 patients with pathologically diagnosed locally advanced NPC in five treatment centers from 2011 to 2012 were randomly divided into two groups. In the test group, one hundred and thirteen patients received two cycles of induction chemotherapy with docetaxel (65 mg/ m2 on day 1) and nedaplatin (80 mg/ m2 on day 1) plus concurrent IMRT with nedaplatin (40 mg/ m2 on day 1). In the control group, 110 patients received two cycles of induction chemotherapy with the same regimens plus concurrent IMRT with cisplatin (40 mg/ m2 on day 1). The survival rates were calculated with the Kaplan?Meier method and the differences in the survival rates between the two groups were analyzed using the log?rank test. Comparison of the incidence rates of adverse reactions between the two groups was made by the chi?square test. Results The follow?up rate was 99?? 1%.The response rates at 3 months after treatment in the two groups were both 100%. The 2?year local recurrence?free, regional recurrence?free, distant metastasis?free, and overall survival rates were 94?? 0%, 94?? 2%, 88?? 2%, and 90?? 3%, respectively, in the test group, versus 93?? 4%, 94?? 1%, 86?? 7%, and 87?? 3% in the control group ( P= 0?? 757、 0?? 478、 0?? 509、 0?? 413). The incidence rates and severity of leucopenia, neutropenia, and thrombocytopenia were significantly higher in the test group than in the control group ( P= 0?? 027 , 0?? 028 , 0?? 035 ) . The incidence rates and severity of hemoglobin reduction and nausea /vomiting were significantly lower in the test group than in the control group (P= 0?? 000,0?? 023). There were no significant differences in the incidence rates of mucositis and xerostomia between the two groups ( P=0?? 483,0?? 781). Conclusions The short?term efficacy of induction chemotherapy with nedaplatin and docetaxel plus concurrent IMRT with nedaplatin is similar to that with cisplatin in the treatment of locally advanced NPC. The mild gastrointestinal reactions can be tolerated by patients. However, the severe myelosuppression should be closely monitored during the treatment.

OBJECTIVE:To evaluate the clinical efficacy of liraglutide and insulin glargine in the treatment of type 2 diabetes mellitus (T2DM) and conduct pharmacoeconomic analysis, and to provide economical and reasonable T2DM treatment plan. METHODS:80 T2DM patients were randomized into liraglutide group and insulin glargine group,with 40 cases in each group. Both groups were given Metformin hydrochloride sustained-release tablet orally 0.5-2.0 g/d,and diabetes mellitus diet and sport training guide after oral antidiabetic drug withdrawal of previous treatment plan. Liraglutide group was given Liraglutide injection hypodermically,0.6-1.2 mg,qd;insulin glargine group was given insulin glargine hypodermically at 22 o’clock,initial dose of 0.2 IU/(kg·d),adjusted according to the levels of PG,FBG,nocturnal blood glucose level till FBG≤7 mmo1/L and 2 h PG ≤10 mmol/L in both group. Treatment course of 2 groups lasted for 12 weeks. The changes of FBG,2 h PG,HbA1c and BMI were ob-served in 2 groups before and after treatment. 2 therapy plans were evaluated and compared by cost-minimization analysis. RE-SULTS:After treatment,the levels of FBG,2 h PG and HbA1c decreased significantly in 2 groups,compared to before treatment, with statistical significance (P<0.05),but there was no statistical significant difference between 2 groups (P>0.05). After treat-ment,BMI of liraglutide group decreased significantly compared with before treatment and insulin glargine group,with statistical significance (P<0.05). There was no statistical significant difference in BMI of insulin glargine group before and after treatment (P>0.05). Cost-minimization analysis showed that the cost of insulin glargine group in reducing FBG,2 h PG and HbA1c were less than liraglutide group,but were more than liraglutide group in reducing BMI. Sensitivity analysis demonstrated the stability and reliability of cost-minimization analysis. CONCLUSIONS:Lira-glutide and insulin glargine have the same clinical efficacy,but insulin glargine need lower cost in blood glucose control,and liraglutide is better therapy plan for body weight control.

BACKGROUND:Percutaneous injection of bone cement into the vertebral body can enhance the vertebral strength and vertebral stability, and obtain pain relief. But the bone cement may leakage into the paravertebral vessels during injection, and may back to the right ventricle and flow into the pulmonary artery through vena cave and thus causing pulmonary embolism.
OBJECTIVE:To evaluate the relationship between cement paravertebral vascular leakage and pulmonary cement embolism during percutaneous vertebroplasty.
METHODS:Total y 134 cases of osteoporotic compression fractures treated with vertebroplasty were retrospectively analyzed. Among them, 23 cases of cement paravertebral vascular leakage were considered as the experimental group, and the 43 cases without cement paravertebral vascular leakage and had the complete imaging data were considered as the control group. The spine and chest X-ray films were taken before and after vertebroplasty to detect whether there were cement paravertebral vascular leakage and pulmonary cement embolism in the patients of two groups.
RESULTS AND CONCLUSION:Among the 134 patients, 23 patients had cement paravertebral vascular leakage, and accounted for 17.2%. Among the 23 patients with cement paravertebral vascular leakage, three cases had pulmonary cement embolism without chest symptoms, and accounted for 13%. No pulmonary cement embolism occurred in the 43 patients without paravertebral vascular leakage of the control group, and there was no significant difference between two groups (P=0.039). Although the patients with cement pulmonary embolism remained asymptomatic, pulmonary cement embolism remained possible if cement paravertebral vascular leakage was detected during vertebroplasty.

Objective:
To explore the clinical features and genetic characteristics of myoclonic-atonic epilepsy (MAE) caused by SLC6A1 gene mutation.
Methods:
The clinical data of a patient with SLC6A1 gene mutation from Xiangya Hospital of Central South University was collected. The related literatures were reviewed from Wanfang Data, China National Knowledge Infrastructure, PubMed (until July 2019) by using keywords " SLC6A1" and " myoclonic-atonic epilepsy" . The characteristics of SLC6A1 gene mutation and the clinical phenotype of children with myoclonic-atonic epilepsy were summarized.
Results:
A 8 year and 8 months old girl was enrolled in the study. Her first attack happened at the age of 19 months, and multiple seizure types including myoclonic-atonic, atonic and absence were observed. The seizures were well controlled by valproate (VPA), but she has mild-moderate intellectual disability. Whole exome-sequencing study identified a de novo nonsense variant of c. 46G>T(p.Glu16*)in SLC6A1 gene. A total of 27 cases including the present case with SLC6A1 gene mutation were analyzed. 22 mutations were identified, including 11 missense mutations, 5 nonsense mutations, 3 frameshift mutations, 2 splicing mutation and 1 with chromosome microdeletion. Among them 26 patients had more one type of seizures, 20 cases had absence seizures, 17 cases had atonic seizures, 14 cases had myoclonic seizures, 11 cases had myoclonic-atonic seizures, 4 cases had generalized tonic-clonic seizures, 3 cases had eyelid myoclonias, 2 cases had nonconvulsive status epilepticus and 2 cases had tonic seizure. 24 patients had described intelligence assessment. Among them, 18 had developmental delay before epilepsy onset, 11 had developmental regression after onset. There were 9 cases with autistic features, 4 cases with attention deficit hyperactivity disorder and 3 cases with ataxia. The seizures of 17 cases were controlled, 4 cases had partial seizure control, 3 cases had no significant improvement, and other 3 cases were unclear.
Conclusions
The main clinical feature of MAE patients with SLC6A1 gene mutations is absence and atonic seizures, cognition before epilepsy onset can be impaired, and some patients had behavioral problems, such as autistic features or attention deficit hyperactivity disorders. VPA is recommend as first-line treatment.
