Hyperthermic intraperitoneal chemotherapy plus high-frequency diathermic therapy followed by intravenous chemotherapy versus intravenous chemotherapy alone for postoperative adjuvant treatment of gastrointestinal cancer: a comparative research study.

Purpose: To evaluate the therapeutic efficacy and toxicity of hyperthermic intraperitoneal chemotherapy (HIPEC) plus high-frequency diathermic therapy (HFDT) followed by intravenous chemotherapy vs intravenous chemotherapy alone for adjuvant treatment of postoperative gastrointestinal neoplasms.

Methods: Fifty-two gastrointestinal carcinoma patients who were radically operated were enrolled and divided into the treatment group and the control group. In the treatment group, 25 patients were treated with combination of HIPEC+HFDT and subsequent intravenous chemotherapy, while in the control group 27 patients received intravenous chemotherapy alone.

Effect of arctiin on glomerular filtration barrier damage in STZ-induced diabetic nephropathy rats.

Diabetic nephropathy (DN) is the major life-threatening complication of diabetes. Abnormal permeability of glomerular basement membrane plays an important role in DN pathogenesis. This study was performed to assess the effect of arctiin, the lignan constituent from Arctium lappa L.

[Study on the extraction of total flavonoids from Mentha spicata by ultrasonic method].

The optimal conditions of total flavonoids extraction from Mentha spicata were identified by orthogonal test. The results showed that the ethanol concentration and the ultrasonic time had significant effect on the extraction of total flavonoids and the optimum conditions of extraction were A3B3C1D1, which were as follows: the ethanol concentration was 50%, the ultrasonic time was 40 min, the solid-liquid ratio was 1 g: 50 mL and the temperature of extraction was 60 degrees C, On the basis of the extracting method above, the content of total flavonoids in Mentha spicata was 0.0951 mg/mg.

[Determination of trace lead in traditional Chinese herbal medicine Astragalus by microwave digestion-CTAB enhancing-continual flow ingection hydride generation-ICP-AES].

A new method using microwave digestion technique was developed for the determination of lead in Astragalus by CTAB enhancing-continual flow hydride generation-inductively coupled plasma atomic emission spectrometry (HG-ICP-AES). The experimental conditions of microwave digestion and hydride generation were optimized. This method shows a linear range of 0.
