ABSTRACT
Hypercalcemic crisis (HC) is a rare but critical electrolyte disorder, which may result in death if rapid correct management is not given due to the injury of the neurologic, cardiovascular and renal systems. Severe primary hyperthyroidism (PHPT) is listed as the most common cause of hypercalcemic crisis. Prompt surgical removal of the parathyroid glands is the most effective cure for HC. Nevertheless, hypercalcemic crisis after a successful parathyroidectomy is infrequent. Now, we report a case admitted to the Department of General Surgery of the Shanghai Jiao Tong University Affiliated Sixth People’s Hospital about a successful therapy of hypercalcemic crisis postparathyroidectomy in Sep. 2019, aiming to remind clinicians of the individualized program of calcium supplement after surgery of hyperparathyroidism and emphasize the value of renal dialysis in HC.
ABSTRACT
Objective To build a method for determination of berberine, epiberberine, coptisine and palmatine in Shutongantai Capsules by HPLC.Methods Thermo C18 column (5μm, 4.0 mm× 250 mm) was used with acetonitrile-0.05 mol/L potassium dihydrogen phosphate solution (50∶50, 0.4 g sodium dodecyl sulfate was added in each 100 mL solution, to adjust the pH 4.0 with phosphoric acid) as mobile phase;the flow rate was 1.0 mL/min;detection wavelength was 345 nm;column temperature was 30℃.Results Berberine hydrochloride showed a good linear relationship in the range of 0.180 34-0.901 68μg (r=0.999 8).Conclusion The method is simple, accurate and reproducible, and can be used for the quality control of Shutongantai Capsules.
ABSTRACT
Objective To establish a quality standard of Shutongantai Capsules. Methods Thermo C18 column was used with methanol-0.1% phosphoric acid as mobile phase. The flow rate was 1.0 mL/min, detection wavelength was 254 nm, and column temperature was 30 ℃. Results Emodin showed a good linear relationship in the range of 0.016-0.080 μg (r=0.999 6). Chrysophanol showed a good linear relationship in the range of 0.032-0.160 μg (r=0.999 8). Conclusion The established method is simple, feasible and reproducible, and can be used for the quality control of Shutongantai Capsules.
