Effects of Chinese herbal medicine Yiqi Huaju Qingli Formula in metabolic syndrome patients with microalbuminuria: a randomized placebo-controlled trial / 中西医结合学报

<p><b>BACKGROUND</b>Microalbuminuria (MAU) is a key component of metabolic syndrome (MetS) and is an early sign of diabetic nephropathy as well. Although routine Western medicine treatments are given to MetS patients to control high blood pressure, hyperglycemia and dyslipidemia, some patients still experience progressive renal lesions and it is necessary to modify and improve the treatment strategy for MetS patients.</p><p><b>OBJECTIVE</b>To investigate the efficacy of Yiqi Huaju Qingli Herb Formula, a compound traditional Chinese herbal medicine, in MetS patients with MAU when it is combined with routine Western medicine treatment.</p><p><b>DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS</b>Sixty patients with MetS were randomized into the Chinese herbal formula group (CHF, Yiqi Huaju Qingli formula treatment in combination with Western medicine) and control group (placebo in combination with Western medicine). All treatments were administered for 12 weeks.</p><p><b>MAIN OUTCOME MEASURES</b>Urinary microalbumin (MA), urinary albumin-to-creatinine ratio (UACR), 24-hour total urine protein (24-hTP), body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), fasting plasma glucose (FPG), 2-hour postprandial plasma glucose (2-hPPG), glycosylated hemoglobin (HbA1c), homeostasis model assessment for insulin resistance (HOMA-IR), blood lipid profile and blood pressure were observed.</p><p><b>RESULTS</b>Compared with the control group, CHF treatment significantly decreased BMI (P<0.05), WC (P<0.01) and WHR (P<0.01). Both groups had significant decreases in FPG, 2-hPPG, HbA1c, HOMA-IR, MA, and UACR, with CHF treatment showing better effects on these parameters compared with the control treatment (P<0.05). Both treatments significantly reduced the levels of total cholesterol, low-density lipoprotein cholesterol and triacylglycerol (TAG), and a greater reduction in TAG was observed with CHF treatment (P<0.05). The level of high-density lipoprotein cholesterol did not change in the control group after treatment (P>0.05), whereas it significantly increased with CHF treatment (P<0.01). Compared with before the treatment, significant decreases in systolic blood pressure, diastolic blood pressure and mean arterial blood pressure were observed in both groups (P<0.01). However, there was no significant difference between the two groups (P>0.05).</p><p><b>CONCLUSION</b>Combined treatment of Yiqi Huaju Qingli Formula and Western medicine significantly alleviated MAU, which may correlate with the improvement of insulin sensitivity and glucose and lipid metabolism. TRIAL REGISTRATION IDENTIFIER: This trial was registered in the Chinese Clinical Trial Registry with the identifier ChiCTR-TRC-11001633.</p>

Apigenin affects semen parameters in male mice / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the effect of apigenin on semen parameters in male mice.</p><p><b>METHODS</b>Totally 100 healthy male mice of Kunming strain were randomly divided into 5 groups according to the body weight: negative control, solvent control, low-dose apigenin, median-dose apigenin and high-dose apigenin, the latter three groups given intragastric apigenin at a fixed time every day for 7 and 14 days.

Effect of surgical intervention on refractory posttraumatic epilepsy: a clinical analysis / 中华神经医学杂志

Objective To investigate the clinical characteristics ofposttraumatic epilepsy, the correlation between epileptogenic foci and encephalomalacia, and the therapeutic effects of surgical intervention. Methods A retrospective analysis was performed among 13 patients with refractory post-traumatic epilepsy who received surgical intervention between February, 2003 and April, 2006. Results The first seizure attack occurred 0.5-13 years (mean 5.3 years) after craniocerebral injury in these patients. The epileptogenic loci were located around the encephalomalacia (ranging from 2 to 7 cm) in 8 patients, in the temporal lobe in 5 patients, in the medial temporal lobe in 4 patients (3 of whom sustained the injuries at 1.5-5 years of age with hippocampal glial proliferation shown by postoperative pathological examination), and in the neocortex of the temporal lobe in 1 case. All the patients underwent the operations under close monitoring of the cortical electroencephalogram, and 4 also received cranioplasty. The total effective rate of the surgery was 92.3% with an excellent outcome rate of 84.6% in the follow-up for 2-5 years. Conclusion The epileptogenic loci of posttraumatic epilpsy are usually adjacent to the encephalomalacia, and hippocampal sclerosis can be likely in patients with severe cerebral injury below 5 years of age. gefractory posttraumatic epilepsy often has favorable surgical outcome, and prompt surgery is suggested after the diagnosis.

Role of aminoguanidine in brain protection in surgical brain injury in rat.

The study investigated the effect of aminoguanidine (AG) on surgical brain injury (SBI) in rat. AG (75, 150 and 300 mg/kg, i.p.) was administered immediately following surgical resection. Using a SBI model, we found that AG (150 mg/kg) significantly reduced cerebral edema, while AG at the doses of 75 and 300 mg/kg had no effect. And AG (150 mg/kg) significantly reduced Evans Blue extravasation into brain tissue and improved the neurological outcome compared to control group. Moreover, the expression of TNF-alpha and nuclear factor-kappaB (NF-kappaB) mRNA and protein in brain tissue at the edge of the resection site increased at 24h after SBI, which could be significantly attenuated by the treatment with AG via RT-PCR and Western blots methods. Our results demonstrated that SBI causes increased brain edema, BBB disruption and inflammation along the periphery of the site of surgical resection, which could be significantly improved by the treatment of AG.
