Rhizopus rot of peach fruits could be significantly suppressed by Pichia membranefaciens. Polyphenol oxidase (PPO), peroxidase (POD) and phenylalanine ammonium-lyase (PAL) activities induced by inoculation with P. membrane faciens or R. stolonifer were studied in postharvest peach fruits. The activities of PPO and PAL in peaches increased significantly after being inoculated with P. membrane faciens + R. stolonifer by 24 h, the activities maintained at a high level throughout the experiment. Under the condition of infected with R. stolonifer alone, activity of PPO and PAL could also increased, but the levels were lower than those treated with P. membrane faciens+ R. stolonifer. However, fruits inoculaed with P. membrane-faciens + R. stolonifer or R. stolonifer alone did not stimulated POD activity. The results suggest that the activation of these defense enzymes is involved in the action of P. membrane faciens against R. stolonifer.

On the basis of definition and classification of rural public goods, this paper analyses the status quo of public goods supply in vast rural areas of China, and it indicates that the electricity and communication facility in rural areas have not yet been popularized; the culture and education facility is critically backward; the medical care and social warfare institutions are short. It points out the rational supply model of public goods as follows: the government plays dominant role in the public goods supply with a large amount of investments, related to the quality of living and production of multitudinous farmers; small wieldy quasi-public goods that can be easily supplied and marginalized public goods can introduce multiplex supply main body under the framework of government guidance. According to this model, corresponding policy suggestions are put forward as follows: increase financial inputs, and perfect local financial system; actively encourage the majority of farmers in rural areas to participate in public goods supply mechanism, so that the supply has pertinence; vigorously develop multiplex supply system of rural public goods, to ensure effective supply.

Current treatments for epilepsy can only manage the symptoms of the condition but cannot alter the initial onset or halt the progression of the disease. Consequently, it is crucial to identify drugs that can target novel cellular and molecular mechanisms and mechanisms of action. Increasing evidence suggests that axon guidance molecules play a role in the structural and functional modifications of neural networks and that the dysregulation of these molecules is associated with epilepsy susceptibility. In this review, we discuss the essential role of axon guidance molecules in neuronal activity in patients with epilepsy as well as the impact of these molecules on synaptic plasticity and brain tissue remodeling. Furthermore, we examine the relationship between axon guidance molecules and neuroinflammation, as well as the structural changes in specific brain regions that contribute to the development of epilepsy. Ample evidence indicates that axon guidance molecules, including semaphorins and ephrins, play a fundamental role in guiding axon growth and the establishment of synaptic connections. Deviations in their expression or function can disrupt neuronal connections, ultimately leading to epileptic seizures. The remodeling of neural networks is a significant characteristic of epilepsy, with axon guidance molecules playing a role in the dynamic reorganization of neural circuits. This, in turn, affects synapse formation and elimination. Dysregulation of these molecules can upset the delicate balance between excitation and inhibition within a neural network, thereby increasing the risk of overexcitation and the development of epilepsy. Inflammatory signals can regulate the expression and function of axon guidance molecules, thus influencing axonal growth, axon orientation, and synaptic plasticity. The dysregulation of neuroinflammation can intensify neuronal dysfunction and contribute to the occurrence of epilepsy. This review delves into the mechanisms associated with

AIM: To evaluate the efficacy of sequential use of transarterial chemoembolization (TACE) and percutaneous cryosurgery for unresectable hepatocellular carcinoma (HCC). METHODS: Four hundred and twenty patients were enrolled in this study. The patients, who were considered to have unresectable tumors due to their location or size or comorbidity, were divided into sequential TACE-cryosurgery (sequential) group (n = 290) and cryosurgery alone (cryoalone) group (n = 130). Patients in the sequential group tended to have larger tumors and a greater number of tumors than those in the cryo-alone group. Tumors larger than 10 cm in diameter were only seen in the sequential group. TACE was performed with the routine technique and percutaneous cryosurgery was conducted under the guidance of ultrasound 2-4 wk after TACE. RESULTS: During a mean follow-up period of 42 ± 17 mo (range, 24-70 mo), the local recurrence rateat the ablated area was 17% for all patients, 11% and 23% for patients in sequential group and cryoalone groups, respectively (P = 0.001). The overall 1-, 2-, 3-, 4and 5-year survival rate was 72%, 57%, 47%, 39% and 31%, respectively. The 1and 2-year survival rates (71% and 61%) in sequential group were similar to those (73% and 54%) in cryo-alone group (P = 0.69 and 0.147), while the 4and 5-year survival rates were 49% and 39% in sequential group, higher than those (29% and 23%) in cryo-alone group (P = 0.001). Eighteen patients with large HCC (> 5 cm in diameter) survived for more than 5 years after sequential TACE while no patient with large HCC (> 5 cm in diameter) survived more than 5 years after cryosurgery. The overall complication rate was 24%, and the complication rates were 21% and 26% for the sequential and cryo-alone groups, respectively (P = 0.06). The incidence of hepatic bleeding was higher in cryo-alone group than in sequential group (P = 0.02). Liver crack only occurred in two patients of the cryoalone group. CONCLUSION: Pre-cryosurgical TACE can in
