OBJECTIVE:To establish a method for determination of carbazochrome sodium sulfonate for injection.METH_ ODS:C 18 was used as chromatographic column;the mobile phase consisted of0.12%ammonium dihydrogen phosphate buffer solution-absolute alcohol(925∶75)with detection wavelength at363nm and flow rate at0.8ml/min.The sample size was10?l and the column temperature was25℃.RESULTS:Linear relation was achieved when the concentration of carbzochrome sodium sulfonate was within the range of0.08865mg/ml～0.4432mg/ml(r=0.9999,n=5).The mean recovery rate was99.89%(RSD=1.53%,n=9).CONCLUSION:This method is simple,rapid,accurate,precise,and which can be used as the quality control of carbzochrome sodium sulfonate for injection.

Objective: To analyze the serum concentration results of sodium valproate (VPA) and carbamazepine (CBZ) and explore the relationship between the serum concentration and age, clinical efficacy and adverse reactions to provide reference for the rational clinical use.Methods: Retrospective analysis was used to collect the clinical data of the patients from March 2015 to March 2016, including gender, age, clinical diagnosis, medication, usage and dosage, the last medication time, sampling time, blood concentration and the other related data, and the data were compared and analyzed.Results: Totally 2608 samples were collected, including 2 205 ones for VPA and 403 ones for CBZ.Totally 1 123 cases (50.93%) of VPA and 292 cases (72.46%) of CBZ were within the range of therapeutic windows.In the 2 205 cases of VPA, 1 814 cases (82.27%) were with single drug treatment, and the serum concentration lower than the lower limit of therapeutic window accounted for 790 cases (43.55%) with the effective rate of 43.55% for epilepsy.The serum concentration within the range of therapeutic window accounted for 921 cases (50.77%) with the effective rate of 88.27% for epilepsy, and that higher than the higher limit of therapeutic window accounted for 103 cases (5.68%) with the effective rate of 81.55%.As for CBZ, the number was 58 cases (22.39%) with the effective rate of 48.28%, 195 cases (72.29%) with the effective rate of 79.49% and 6 cases (2.32%) with the effective rate of 83.34%, respectively.Totally 391 cases (87.21%) of VPA combined with the other antiepileptic drugs, such as levetiracetam and lamotrigine.The effect of age on the serum concentration of VPA and CBZ was significant (P<0.05).Conclusion: There are great individual differences in serum concentration of VPA and CBZ among patients.The therapeutic effect and adverse reactions of VPA and CBZ are closely related to the serum concentration.Monitoring the serum concentrations may provide evidence for the rational administration and plays an important role in the treatment of epilepsy.

OBJECTIVE: To exlpore the eff ect of depsides salts from Salvia miltiorrhiza on human hepatoma cell line SMMC-7721 xenograft tumors and the possible mechanisms. METHODS: A total of 36 nude mice were divided into 6 groups: A model group, a negative control group, a positive control group, and 3 treatment groups at low, middle or high dose (n=6). The tumor model of nude mice was given depsides salts at a dose of 10, 20 or 50 mg/kg every 3 day for 16 days. Then samples of subcutaneous tumors in nude mice were collected. The morphological changes of tumor samples were observed by HE staining and the expression of vascular endothelial growth factor (VEGF) and the tumor antigen Ki67 was detected by immunohistochemical method. RESULTS: The tumor growth was inhibited by all doses of depsides salts. The morphology of tumors was shrinkage, broken and irregularly arranged compared with the tumors in the model group and the negative control group. Morphological changes were more obvious in tumors with treatment at high dose. Expression of VEGF and Ki67 in treatment groups and the positive control group were lower than that in the model group and the negative control group, with a significant difference (P<0.05). CONCLUSION Depsides salts from Salvia miltiorrhiza can inhibit the growth of human hepatoma cell line SMMC-7721 tumor in nude mice, which is related to the inhibition of Ki67 and VEGF.

Acute osteofascial compartment syndrome is a series of symptoms and signs caused by acute ischemia of muscles and nerves in osteofascial compartment. If it is not treated in time, it can lead to tissue necrosis. It is rare that it is caused by rodenticide poisoning. Such patients are often difficult to diagnose and treat early and have poor prognosis. In May 2018, a patient with acute osteofascial compartment syndrome caused by anticoagulant rodenticide poisoning was admitted to the Twelfth Hospital of Guangzhou City. After systematic treatment, he finally recovered and discharged. The early manifestations of this patient were mainly coagulation dysfunction, and finally acute osteofascial compartment syndrome. 5 days later, the diagnosis was made, and the operation of incision decompression and vacuum sealing drainage (VSD) was performed.
