Results The results of TLC showed that relevant spots were clear without interference against the negative sample. The calibration curves for Paeoniflorin and Tanshinone ⅡA were found to be liner within the range of 0.448-4.48μg, 0.057 6-0.576μg, respectively. The correlation coefficients were 0.999 4 and 0.999 5, respectively. The average recoveries were 99.93%and 99.75%, with RSD of 1.98%(n=9) and 1.70%(n=9), respectively. Conclusion The method is accurate, reliable, stable, rapid, and reproducible, and can be used for the quality control and evaluation of Jiangzhi Fugan Capules.

Objective To establish the quality standard for Jinyin Lidan Oral Liquid. Methods Artemisiae Scopariae Herba, Taraxaci Herba, Aurantii Fructus and Schisandrae Chinensis Fructus in Jinyin Lidan Oral Liquid were identified by TLC. The contents of naringin and neohesperidin were determined by HPLC. The HPLC separation was performed on Phenomenex C18 column (4.6 mm × 250 mm, 5 μm) with the mobile phase of methanol-0.1% phsophonic acid solution and gradient elution. The UV detection wavelength was 254 nm;flow rate was 1.0 mL/min;column temperature was 25 ℃.

Objective:To investigate the optimal water extraction process of Jinyin Lidan oral liquids. Methods:An orthogonal de-sign was used in the extraction optimization using the yield and content of chlorogenic acid,narigin and neohesperidin as the evaluation indices and the volume of water,extraction times,extraction time and soaking time as the influencing factors. The contents of chloro-genic acid,narigin and neohesperidin were detected by HPLC to screen the best extraction technology. Results:The best water extrac-tion conditions were as follows:the amount of the added water was 8 times of the medicinal materials,the soaking time was 1 h,and the decoction was carried out twice with the duration of 1. 5 h for each. Conclusion:The process is stable and reasonable,which pro-vides research foundation for the production and quality control.

Objective To study the dynamic changes of plasma C-reactive protein (CRP) and cortisol (COR) and their clinical value in prognosis of patients with sepsis. Methods Daily CRP and COR detection was conducted to record the dynamic changes of CRP and COR for cases of sepsis patients in ICU then the rela-tionship between dynamic changes of serum CRP and COR and prognosis were analyzed. Results Serum CRP and COR levels of dead patients were significantly higher than those of survival patients after treatment (P <0.05). According to the difference of the dynamic changes of CRP and COR, the data were divided into typeⅠ:sustained elevated type , typeⅡ: up-and-down type , type Ⅲ: fluctuated type and type Ⅳ: normal or mild ele-vation type. The mortality of CRP typeⅠ patients was significantly higher than that of type Ⅱ and type Ⅳ(P <0.001). The mortality of COR typeⅠ and COR Ⅲ patients was significantly higher than that in COR Ⅱand COR Ⅳ (P < 0.001). Further analysis showed that the mortality of group with significant elevation of CRP and COR were obviously higher than that of group with significant increase of CRP or COR and that of group with no significant elevation of CRP and COR (P < 0.001); the mortality of group with significant increase of CRP or COR was also significantly higher than that of group with no significant elevation of CRP and COR (P < 0.001). Conclusions The dynamic changes of COR and CRP in patients with sepsis present certain regularity and monitor-ing the dynamic changes of the two provides accurate assessment of the prognosis of sepsis.

OBJECTIVE: To analyze the clinical characters, surgical treatments and prognosis of differentiated thyroid carcinoma (DTC) with laryngeal or tracheal invasion. METHOD: Forty-six cases including 33 papillary and 13 follicular were retrospectively reviewed. Thirty-four cases with tracheal invasion received conservative resection (17), window resection (11) and sleeve resection (6). One case with subglottic invasion was performed subglottic partial laryngectomy. Eleven cases with trachea-laryngeal invasion received total laryngectomy(4), 3 shave technique and 4 preservative laryngectomy. RESULT Complications included infections and hypocalcaemia, 15 patients got permanent fistula. 5-year survival rate in cases of tracheal shave resection was 88.2%, while 63.6% in those of window resection and 83.3% in those of sleeve resection. Survival rate within 5 years of patients received preservative laryngectomy was 62. 5%. Conclusion: With meticulous preoperative examination and positive surgical treatment, both survival rate and quality of life could be improved in patients of DTC with laryngeal or tracheal invasion.

Objective:To explore the electro-clinical characteristics of sleep-related hypermotor epilepsy (SHE) in rapid eye movement (REM) stage.Methods:Five patients of SHE in REM stage were studied and followed up in the Electroencephalogram Monitoring Center, Department of Neurology, Xijing Hospital, the Air Force Military Medical University, from January 2016 to August 2021.Results:Among the 5 patients, there are 3 male patients, aged 21 to 46 years. A total of 23 seizures were monitored in 5 patients, of which 22 occurred in REM sleep and 1 occurred in non-REM Ⅲ sleep. Each attack lasted from 30 seconds to 1 minute, and was manifested as "hyperkinetic attack" during sleep, with or without disturbance of consciousness. There were no obvious abnormalities in electroencephalography during 13 attacks, with the focal sharp slow waves or slow waves during 9 attacks, and the focal slow waves occurrence at the end of the 10 attacks.Conclusion:Most of the hypermotor epileptic seizures in REM stage started from awakening reaction, and the interictal discharges occured in waking and non-REM sleep stage, which is necessary to distinguish from the REM sleep behavior disorder.

Objective:To establish a method of measuring the contents of gallic acid, brevifolin, corilagin, geraniin, ellagic acid and rutin in Phyllanthus urinaria L. simultaneously with fingerprint study for analysis. Methods:Phyllanthus urinaria L. was extracted by ultrasound with 50% methanol. Chromatographic separation was performed on a Phenonmenex Luna C18 (4.6 mm×250 mm, 5 μm). The mobile phase consisted of acetonitrile (A) and 0.1% phosphoric acid aqueous solution (B) with gradient elution. The flow rate was 1.0 ml/min. The column temperature was 25 ℃, and the injection volume was 10 μl. The detection wavelength was 270 nm. HPLC fingerprints of Phyllanthus urinaria L. from different habitats was established. PCA and OPLS-DA were used to analyze the differences in chemical components of different habitats. Results:Gallic acid, brevifolin, corilagin, geraniin, ellagic acid and rutin showed good linearity at 0.042 8-0.641 6, 0.033 4-0.501 4, 0.142 2-2.133 1, 0.383 1-5.746 5, 0.063 1-0.946 2 and 0.019 2-0.287 8 μg, respectively. The average recovery rate of them was 103.65%, 96.39%, 101.85%, 95.04%, 98.79% and 98.33%, respectively. The HPLC fingerprints of different habitats contained 14 characteristic common peaks, and six compounds characteristic peaks were identified. PCA analysis showed that the chemical components of Phyllanthus urinaria L. from different habitats were different. Geraniin, ellagic acid and corilagin were screened by OPLS-DA. Conclusions:The method is efficient, accurate and sensitive, which can be used to measure the six components in Phyllanthus urinaria L.. The established HPLC fingerprint of different habitats combined with the measrurement method of six components can be used for the quality control and evaluation of Phyllanthus urinaria L..
