The paper is to report the observation of pharmacokinetic changes of the characteristic ingredients in the combinations of different-dose herbs of Shaoyao-Gancao decoction. After the establishment of HPLC analytical method of plasma effective constituents, rats were orally administered with different-dose herbs of Shaoyao-Gancao decoction. Blood samples at different times after administering these decoctions were collected, and then were analyzed by HPLC fingerprints technology. Pharmacokinetic parameters of characteristic peaks were analyzed by SPSS 15.0 software and DAS 2.0. At last, we looked for the correlation of those pharmacokinetic parameters and the dosage of Gancao. The best dose of Shaoyao-Gancao decoction was at the ratio of 4 to 4, which was consistent with the dose commonly used in ancient times. The absorption of characteristic peaks from Shaoyao-Gancao decoction was related with the dosage of Gancao, and there existed interaction between each characteristic ingredients. There existed the right dose-ratio of Shaoyao and Gancao to get the best effect. The absorptions of effective constitutents were mutual waxing and waning in order to increase biological effects together. It's demonstrated the compatibility connotation at a right dose-ratio of Shaoyao-Gancao decoction through the angle of pharmacokinetics.

AIM To investigate the effects of several 5-hydroxytryptamine(5-HT) subtype receptor antagonists on late slow excitatory postsynaptic potential(LS-EPSP) of the neurons of guinea pig inferior mesenteric ganglion(IMG). METHODS Intracellular recordings were made from neurons of the isolated guinea pig IMG. RESULTS Cyproheptadine and BRL 24924 suppressed LS-EPSP of 5-HT sensitive neurons reversibly, while mianserin, MDL 72222 and spiperone showed no significant effect. Continuous superfusion of IMG with MCPP suppressed LS-EPSP of 5-HT sensitive neurons by 5-HT 1P receptor desensitizated. CONCLUSION LS-EPSP of 5-HT sensitive neuron is mediated by 5-HT 1P subtype receptor.

Objective To study the asymmetry of the soft tissue thickness of upper eyelids in Shanghai female undergraduates undergoing double eyelid surgery.Methods Data were collected in 565 female students from Shanghai universities.Before surgery,oblique sagittal view images of the upper eyelids by 3.0T MRI were obtained and the following parameters were measured: soft tissue thickness at upper tarsal plate margin and upper central tarsal plate,sub-eyebrow and intra-orbital septum fat pad areas,and whole upper eyelid soft tissue areas.The resected orbicularis and intra-orbital septum fat were weighed by a highly accurated electronic balance.The eyelid asymmetry index (EAI) was calculated.Results The MRI (U/U2) central tarsal plate soft tissue thickness were:4.46±0.90 in the right side and 3.78±1.01 in the left; the intra orbital septum fat areas were:172.33±49.29 in the right and 136.34±37.42 in the left; the whole tissue areas were: 697.13±146.99 in the right and 500.66±158.87 in the left (P＜0.01 for all).The weight of the resected orbicularis oculi muscle and intra orbital septum fat pad were (0.18±0.05) g and (0.17±0.06) g for the right side,and (0.15±0.04) g and (0.06±0.05) g for the left side (P＜0.01 for all),respec tively.The orbicularis EAI was 0.17±0.06,and the intra orbital septum fat EAI was 0.41 ±0.08.Conclusions The asymmetric phenomenon of the upper eyelids' soft tissue thickness is commonly found in the Shanghai female undergraduates,and the main manifestation is that orbicularis and intra orbital septum fat in right side are thicker than that in the left.

One case of traumatic carotid-cavernous fistula (TCCF) with small fistula treated by transarterial detachable coil embolization was reported. The intermittent ipsilateral carotid compression was used to identify the final blocking of the residual fistula. The follow-up digital subtraction angiography showed that the TCCF was cured finally. From this case, we conclude that this method may be an effective way to treat TCCF with small fistula.

Objective:To investigate the clinical and imaging characteristics of liver density changes in patients with initial-treated drug-sensitive secondary tuberculosis during standardized treatment and after withdrawal when cured.Methods:A retrospective analysis was conducted of 34 patients with initial-treated drug sensitive pulmonary tuberculosis in Beijing Chest Hospital of Capital Medical University and the First Affiliated Hospital of Xinxiang Medical University from January 2014 to April 2019. The chest computed tomography (CT) examination and sputum culture were performed before treatment. The patients received the standardized treatment and they were divided into three groups according to the course of treatment (three, nine and 12 months). Liver density and liver function were followed up during treatment (three, six, nine and 12 months) and after drug withdrawal (3, 6 and 12 months). The measurement data were analyzed by t-test. Results:The average liver density of these three groups gradually decreased during the treatment period, and gradually increased after drug withdrawal. There were five and nine cases of fatty liver occurred at three and six months of treatment in the six-month treatment group, respectively; and six, two and zero cases of fatty liver occurred at three, six, and 12 months after drug withdrawal, respectively. There were four, eight and 11 cases of fatty liver occurred at three, six, and nine months of treatment in the nine-month treatment group, respectively; and seven, two and zero cases occurred at three, six, and 12 months after drug withdrawal, respectively.There were five, 10, 14 and 14 cases of fatty liver occurred at three, six, nine and 12 months of treatment in the 12-month treatment group, respectively; and 12, 10 and five cases occurred at three, six, and 12 months after drug withdrawal, respectively. During the course of treatment, the density of livers of some cases decreased unevenly, and the density of right lobe of the liver was lower than the left lobe. The density of left lobe of the liver was (49.8±4.0) HU, (45.0±3.9) HU, (37.0±9.9) HU, (45.3±8.1) HU, (48.4±6.6) HU at the treatment of six, nine and 12 months and drug withdrawal of three and six months, and the density of right lobe of the liver was (44.0±6.1) HU, (37.2±7.7) HU, (25.5±15.8) HU, (38.5±11.7) HU, (43.8±9.9) HU, the differences were statistically significant ( t=4.611, 4.512, 2.307, 2.803 and 2.291, respectively, all P<0.05), while those were not statistically significant among three months of treatment and 12 months after drug withdrawal ( t=1.573 and 1.199, respectively, both P>0.05). There were two cases showed alanine aminotransferase (ALT) and aspartate amiotransferase (AST) accompanied elevated (ALT>2×upper limits of normal (ULN), AST<2×ULN) at three and six months of treatment, with no abnormalities detected of alkaline phosphatase (ALP) and total bilirubin (TBil). Conclusions:The liver density gradually decreases and uneven fatty liver could appear during anti-tuberculosis treatment, but it gradually returns to normal or relieves after drug withdrawal. The degree of fatty liver is not synchronized with the changes of liver function indexes (ALT, AST, ALP and TBil), which belongs to chronic reversible injury.
