ExtHT: A hybrid tracing method for cyber-attacks in power industrial control systems.

Tracing the sources of cyber-attacks in Power Industrial Control Systems (PICS) can help the defense systems to block the attacks, and support the decision of the grid control policies. However, there has been no work on the cyber-attack source traceback for PICS, and the methods for the Internet are not suitable for PICS in terms of fineness, real-time performance, and supporting communication protocols. Therefore, a method for tracing cyber-attacks in PICS is proposed.

Dexmedetomidine Inhibits Inflammation to Alleviate Early Neuronal Injury via TLR4/NF-κB Pathway in Rats with Traumatic Brain Injury.

Purpose - This study aims to explore the potential mechanism of dexmedetomidine in terms of inhibiting inflammation to alleviate early neuronal injury via TLR4/NF-κB pathway in rats with traumatic brain injury. Methods - The model of brain injury was established in rats. After the model was established, the rats were randomly divided into five groups: Sham, Sham + DEX, TBI, TBI + vehicle, and TBI + DEX.

[Effect of electroacupuncture of "Mingmen" (GV 4) on bone morphogenetic protein-2 expression in osteoporosis rats].

Objective: To observe the effect of electroacupuncture (EA) stimulation of "Mingmen" (GV 4) on the bone morphogenetic protein-2 (BMP-2) content and biomechanics in osteoporosis rats so as to explore its mechanism underlying improvement of osteoporosis.

Methods: Fifty female SD rats were randomized into sham operation (sham), model, EA-GV 4, EA-non-acupoint (non-acupoint) and estrogen (medication) groups, with 10 rats in each group. Postmenopausal osteoporosis model was established by removing the rats' bilateral ovaries under anesthesia.

[Our considerations about non-acupoint selection for experimental studies in rats].

Researches on the specificity of acupoints need a contrast of non-acupoint. However, there have been no uniform standards for locating the non-acupoint in both human body and animals. In the present paper, the authors make a review about the methods for locating the non-acupoint in rats during acupuncture experiments in recent decade.

[Discussion on method for locating acupoint "Mingmen" (GV 4) in adult rats].

"Mingmen" (GV 4) is one of the most frequently used acupoints in acupuncture clinic. In recent years, more and more experimental researches have been focusing on GV 4 or acupoint recipe containing GV 4 in rats. Accurate location of GV 4 is probably not only related to fully display its therapeutic effect, but also to help study its underlying mechanisms.

Interaction and relationship between angiotensin converting enzyme gene and environmental factors predisposing to essential hypertension in Mongolian population of China.

Objective: To investigate the association of specific functional gene ACE (I/D) variants of the renin-angiotensin system with essential hypertension (EH) and interaction between ACE (I/D) gene and risk factors for EH in a genetically homogenous Mongolia rural population of China.

Methods: Individuals (n=1099) were recruited from general population of Kezuohouqi Banner in Inner Mongolian Autonomous Region.

Results: The association was found between ACE genotype DD plus ID and EH, with an interaction between ACE genotype DD plus ID and cigarette smoking in an additive model.
