OBJECTIVE: To establish an HPLC method for the determination of rebamipide in rats' plasma and colonic tissue.METHODS: The rats were assigned to receive 4 mg rebamipide chitosan capsule or its gelatin capsule or its CMC-Na solution peros.Then the plasma and colon tissue samples were taken at different time for a determination of the concentration of rebamipide by HPLC gradient elution with Cmax computed.RESULTS: The linear range for rebamipide was from 20~2 000 ng?mL-1.The average extracting recoveries of rebamipide from the plasma and the colon were 88.4% and 90.8%,respectively.After oral administration of 4 mg rebamipide chitosan capsule or its gelatin capsule or its CMC-Na solution,the Cmax of rebamipide in the colon tissue were 5 963.9,2 190.7 and 1 185.8 ng?g-1 respectively versus 252.7,949.0 and 1 023.3 ng?mL-1 respectively in plasma.CONCLUSIONS: The established HPLC gradient elution in the study can be used to determine quantitatively the rebamipide level in plasma or colon tissue for the development of its colon specific delivery preparations.

OBJECTIVE To investigate the application of near-total laryngectomy on the treatment of advanced laryngeal and hypopharyngeal carcinoma. METHODS Thirty patients with laryngeal carcinoma(T3N0~T3N1 17cases,T4N0~T4N1 13cases) and nine with hypopharyngeal carcinoma(T3N0~T3N1 6cases,T4N0~T4N1 3cases) were treated with near-total laryngectomy from May 1995 to March 2003 according to Peaeson modifying method of Tangpingzhang. Concurrent neck dissection were performed in sixteen patients. RESULTS The speech function was obtained in 36 cases (92.3 %) and good swallowing function was obtained in 38 cases(97.4%). Three year survival rates were 73.3% (22/30) in laryngeal carcinoma and 55.6 %(5/9)in hypopharyngeal carcinoma and five year survival rate in laryngeal carcinoma was 61.1%(11/18) . Local recurrence rate was only 2.56 %. CONCLUSION Near-total laryngectomy and speech rehabilitation can be used in most cases that might be treated with total laryngectomy in the past. It can provide satisfying survival rate, good swallowing and speech function.

Objective To evaluate the effect of aescine sodium combined with albumin in the treatment of hypertensive intracerebral hemorrhage after intracranial hematoma minimally invasive removal surgery.Methods 50 patients with hypertensive intracerebral hemorrhage after intracranial hematoma minimally invasive removal surgery were randomly divided into the two groups:the treatment group was treated with aescine sodium and albumin,the control group was treated with the conventional medical drugs;The neural function defect scale,brain edema area of postoperative patients after 1d and 15d,clinical effects after 15d were observed.Results 15d after operation,in the treatment group,the brain edema area was (2.40 ± 0.32) cm2,neural function defect scale was (9.44 ± 2.25) points,which were better than (3.40 ±0.85) cm2 (t =4.721,P <0.01) and (15.65 ±3.04) points(t =3.625,P <0.01).The total effective rate of the treatment group was 88.9%,which was better than 69.6% of the control group(x2 =13.58,P <0.01).Conclusion Aescine sodium combined with albumin can effectively reduce perihematomal brain edema area,improve nerve function defect and clinical effect in the patients with hypertensive cerebral hemorrhage after minimally invasive scavenging surgery.
10.Recent advance in clinical application of deep brain stimulation
Chinese Journal of Neuromedicine 2019;18(9):957-961
Deep brain stimulation is widely used for treatment of neuropsychiatric diseases, showing its unique advantages in the treatment of central nervous diseases, such as epilepsy, Parkinson's disease, essential tremor, drug-refractory psychiatric diseases, drug-refractory pain, improvement of arousal and cognitive functions, and addiction diseases. After more than 30 years of clinical research, animal experiments and material research, the scopes and modes of DBS use have been fully developed, and important progress has been made in seeking better stimulation targets and modes. The complexity and individuality of the disease lead to differences in the response of each patient to DBS treatment, so it is necessary to further clarify its mechanism of action and explore better therapeutic targets and parameters to meet higher clinical requirements. This paper reviews the clinical application of DBS as follows.
