A Review of the Surgical Procedures for the Treatment of Drug-Resistant Epilepsy and Their Seizure Control Outcomes

Background: Drug-resistant epilepsy can be defined as the existence of seizures within 6 months, despite adequate therapy regimens with one or more antiepileptic drugs. Epilepsy surgery has been the standard therapy to help those patients who suffer from drug-resistant epilepsy. The goal of this surgery is to halt or reduce the intensity of seizures. This literature review aims to provide an overview of existing surgical procedures for the treatment of drug-resistant epilepsy and the degree of seizure control they provide based on available literature. Methods: Data were collected from medical journal databases, aggregators, and individual publications. The most used databases were PubMed, Medline and NCBI. Some of the keywords used to search these databases include: “drug resistant epilepsy”, “seizure control”, and “neurosurgery”. Results: Epileptic surgery is divided into resective and non-resective procedures. Studies have shown that a full resection of the epileptogenic brain area increases the probability of seizure eradication, however, the risks of postoperative impairments grow as the resection area is extended. On the other hand, patients who are unsuitable for seizure focus removal by resective surgery, such as those with multifocal seizures or overlapping epileptogenic zone with a functional cortex, may benefit from non-resective surgical options such as Vagus Nerve Stimulation and Responsive Neurostimulation. Conclusion: This literature review discusses the comprehensive treatment of epilepsy, especially the surgical treatment of drug-resistant epilepsy. The reviewed studies have shown that epilepsy surgery has promising outcomes in achieving seizure freedom/reducing seizure frequency with minimal adverse effects when performed correctly with the appropriate choice of surgical candidates.

Effects of Chinese herbal medicine Yiqi Huaju Qingli Formula in metabolic syndrome patients with microalbuminuria:a randomized placebo-controlled trial

BACKGROUND： 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. OBJECTIVE： 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. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS： 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. MAIN OUTCOME MEASURES： 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 （HbAlc）, homeostasis model assessment for insulin resistance （HOMA-IR）, blood lipid profile and blood pressure were observed. RESULTS： 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, HbAlc, 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）. CONCLUSION： Combined treatment ofYiqi 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.

Control Effects of Combination of Plant Induced Resistant Agents against Tobacco Mosaic Virus (TMV)

[ Objective] The paper was explore the control effects of combination of plant induced resistant agents against tobacco mosaic vires （TMV）. [ Method ] The control effects of 6 different combinations of plant induced resistant agents against TMV of flue-cured tobacco cultivar HangDa were studied under the environ- ment of simulated disease nursery. [ Result] The combination of 2 induced agents polypeptide-agent and 3-acetonyl-3-hydroxyoxindole （AHO） had good control effect against TMV, which could obviously delay the incidence time of TMV in infected tobacco plants. With water and Duxiao as control, their average control effects against TMV of tobacco plants during field period reached 69.64% and 43.25% after transplanting for 70 d. They also showed significant superiority accord- ing to Duncan＇s test （p = 0.05 ） in the aspects of plant height and leaf number, and the growth and development condition of leaves was good. Tobacco seedlings carrying TMV virus had no direct correlation with whether the symptoms performed, the seedlings carrying virus would perform symptom only when the incidence condition was suitable. The peak period for the incidence of TMV in seedlings carrying virus was during 19 d after transplanting. Spraying effective agents during nursery stage and field period, as well as promoting quick growth at the initial stage of tobacco seedlings after transplanting were the key measures to control its inci- dence. [ Conclusion] The study provided theoretical basis for preparing the control measures against TMV.

In situ-prepared homogeneous supramolecular organic framework drug delivery systems(sof-DDSs)：Overcoming cancer multidrug resistance and controlled release

Water-soluble three-dimensional porous supramolecular organic frameworks（SOFs） have been demonstrated as a new generation of homogeneous polycationic platforms for anti-cancer drug delivery.The new SOF drug delivery systems（sof-DDSs） can adsorb dianionic pemetrexed（PMX）,a clinically used chemotherapeutic agent instantaneously upon dissolving in water,which is driven by both electrostatic attraction and hydrophobicity.The in situ-prepared PMX@SOFs are highly stable and can avoid important release of the drug during plasm circulation and overcome the multidrug resistance of human breast MCF-7/Adr cancer cells to enter the cancer cells.Acidic microenvironment of cancer cells promotes the release of the drug in cancer cells.Both in vitro and in vivo studies have revealed that sofDDSs considerably improve the treatment efficacy of PMX,leading to 6-12-fold reduction of the IC50 values,as compared with that of PMX alone.The new drug delivery strategy omits the loading process required by most of reported nanoparticle-based delivery systems and thus holds promise for future development of low-cost drug delivery systems
