Resveratrol, as a natural polyphenolic compound, has a wide range of beneficial effects, which includes anti-tumor, cardiovascular protection, anti-oxidant and estrogen-like effects, and so on. Its various physiological properties are closely related to the therapeutic principle for prevention and treatment of high altitude hypoxia injury. Resveratrol may play an important role in relieving or curing high altitude diseases, especially high altitude polycythemia(HAPC). However, the literature about study and application of resveratrol in plateau medicine field is rarely reported up to now. In this review, we summarized the physiological effects of resveratrol, discussed the possible main principle of resveratrol for HAPC therapy, and looked forward to resveratrol's perspective or potential application in high altitude medicine.

The plateau environment is characterized by low oxygen, low air pressure, low temperature, and strong ultraviolet rays, etc. Chronic obstructive pulmonary disease (COPD) is a preventable and treatable chronic lung disease. High altitude environment increases COPD prevalence, clinical manifestation and mortality. The therapeutic window of theophylline drugs for COPD is narrow, and the high altitude environment has an influence on the pharmacokinetics of the drugs. This review summarizes the differences in the prevalence, mortality, clinical manifestation and clinical symptoms of COPD in the plateau and plain, providing a basis for identifying the risk factors of COPD in the plateau areas. The effects of plateau hypoxic environment on the pharmacokinetics of COPD drugs were also discussed. It can provide a rationale for more effective prevention and treatment of COPD at high altitude.

Tumor hypoxia is the necessary process in the development of solid tumors, which is the key factor for drug resistance, recurrence, attack and shift of tumor. Hypoxic tumor cells have a certain extent of tolerance to radiation and chemotherapy. Tumor hypoxia is an important target for medication therapy. In the recent years, the bioreductive drugs targeted tumor hypoxia has made great process in the treatment of tumors. The latest advances of bioreductive drugs targeted hypoxia were reviewed in this paper.

Hepatocellular carcinoma (HCC) is characterized by hypervascularity, indicating that angiogenesis plays a vital role in HCC growth and progression. A number of anti-angiogenic therapies are being utilized in clinical trials in patients with HCC. However, the therapeutic efficacy of anti-angiogenic monotherapy is still insufficient. While inhibition of angiogenesis results in tumor hypoxia and cell death, this inhibition may also activate hypoxia-induced cell signals that may promote HCC progression. Therefore, an understanding of these signals may be essential in designing efficient anti-angiogenic therapies. This review summarizes the role of hypoxia-induced signals in HCC.

AIMTo investigate anti-hypoxia protective roles of the effective component extracted from angelia injection using hypoxia injury model in mice and ECV304 cells separately.

METHODSThe survival time of mice was observed separately under normobaric and hypobaric hypoxia. The activity of ECV304 cells was tested by MTT assay, and the mortality rate was examined by Trypan blue exclusion assay to evaluate the pharmacodynamic effects.

RESULTSAfter exposed to hypoxia the survival time of mice was increased in medicine groups,compared with the control groups (P < 0.05). The cell survival rate was decreased and the cell mortality rate was increased after cells were exposed to hypoxia,while the cell survival rate was significantly increased (P < 0.01), and the cell mortality rate was significantly decreased (P < 0.1) in the medicine groups compared with the control groups.

CONCLUSIONThe effective component extracted from angelia injection can protect against the injury induced by hypoxia.

Diffuse malignant mesothelioma is a rare malignant tumor having poor prognosis. There is still no widely acceptable staging system of the disease and pathologic diagnosis is difficult. Although surgical treatment for diffuse malignant mesothelioma has been controversial, extrapleural peumonectomy in selected patients could prolong the survival when it was combined with adjuvant chemotherapy and radiation therapy. We experienced 4 cases of diffuse malignant mesothelioma for 7 years since 1992, they were treated with extrapleural pneumonectomy without early postoperative mortality. Three patients underwent adjuvant therapy after surgery; chemotherapy in two, and chemo-radiation therapy in one, but one patient could not receive adjuvant therapy because of postoperative complication of hypoxic brain damage due to cardiac torsion and empyema. In this article, we describe surgical experience of extrapleural pneumonectomy and discuss about the controversial points of the disease.

OBJECTIVEPharmacological intervention is an important means for the treatment of hypoxic-ischemic encephalopathy (HIE). As meta-analyses and randomized controlled clinical trials based on evidence-based medicine are able to provide the most reliable evidence for clinical practice, this study searched several databases in order to find the clinical evidence for the pharmacological treatment of neonatal HIE.

METHODSMeta-analyses and randomized (or quasi-randomized) controlled trials (RCT) for pharmacological therapy of HIE in term or late preterm newborn infants were searched from the databases of MEDLINE, EMBASE, Oxford Neonatal Group and Cochrane Library. The relevant literatures were statistically analyzed.

RESULTSFour Meta-analyses and thirteen RCTs were found to be involved in barbiturate, allopurinol, magnesium sulfate, mannitol, naloxone and dopamine therapy. None of the drugs could significantly decrease the mortality and the incidence of seizure or severe neurodevelopmental disabilities in newborn infants with HIE.

CONCLUSIONSCurrent clinical evidence indicates that no individual drug could decrease mortality and improve the neurodevelopmental outcomes in infants with HIE. Problems such as small scale in sampling and discrepancy in the identification of drug efficacy which exist in the clinical trials might lead to the uncertain effect of the drugs, and large sized and collaborative clinical trials are needed in the future.

Hypoxia conditioning could increase the survival of transplanted neuronal progenitor cells (NPCs) in rats with cerebral ischemia but could also hinder neuronal differentiation partly by suppressing mitochondrial metabolism. In this work, the mitochondrial metabolism of hypoxia-conditioned NPCs (hcNPCs) was upregulated via the additional administration of resveratrol, an herbal compound, to resolve the limitation of hypoxia conditioning on neuronal differentiation. Resveratrol was first applied during the in vitro neuronal differentiation of hcNPCs and concurrently promoted the differentiation, synaptogenesis, and functional development of neurons derived from hcNPCs and restored the mitochondrial metabolism. Furthermore, this herbal compound was used as an adjuvant during hcNPC transplantation in a photothrombotic stroke rat model. Resveratrol promoted neuronal differentiation and increased the long-term survival of transplanted hcNPCs. 18-fluorine fluorodeoxyglucose positron emission tomography and rotarod test showed that resveratrol and hcNPC transplantation synergistically improved the neurological and metabolic recovery of stroke rats. In conclusion, resveratrol promoted the neuronal differentiation and therapeutic efficiency of hcNPCs in stroke rats via restoring mitochondrial metabolism. This work suggested a novel approach to promote the clinical translation of NPC transplantation therapy.

OBJECTIVE: To study the effect of different melatonin treatment regimens on long-term behavior and white matter damage in neonatal rats with hypoxic-ischemic brain damage (HIBD), and to seek an optimal melatonin treatment regimen. METHODS: Healthy Sprague-Dawley rats, aged 7 days, were randomly divided into four groups: sham-operation, HIBD, single-dose immediate treatment (SDIT), and 7-day continuous treatment (7DCT), with 8 rats in each group. A neonatal rat model of HIBD was prepared according to the classical Rice-Vannucci method. On day 21 after HIBD, the Morris water maze test was used to evaluate spatial learning and memory abilities. On day 70 after HIBD, immunofluorescence assay was used to measure the expression of neuronal nuclear antigen (NeuN) in the cerebral cortex and the hippocampal CA1 region of neonatal rats, and double-label immunofluorescence was used to measure the expression of myelin basic protein (MBP) and neurofilament 200 (NF200) in the corpus striatum and the corpus callosum. RESULTS: The results of the Morris water maze test showed that the SDIT and 7DCT groups had a significantly shorter mean escape latency than the HIBD group, and the 7DCT group had a significantly shorter mean escape latency than the SDIT group ( CONCLUSIONS Both SDIT and 7DCT can improve long-term behavior and reduce white matter damage in neonatal rats with HIBD, and 7DCT is more effective than SDIT.
