Post-cardiac arrest syndrome (PCAS) is one of the most common medical emergencies in children.The fatality rate and disability rate are extremely high.Pathogenesis of PCAS remains incompletely clear,and clinical manifestation is complicated.The treatment is mainly limited to supportive care.In recent years,the phases of PCAS are defined according to the pathophysiological changes and clinical prognosis.Investigators also made some advances in the fields of pathophysiological changes and clinical treatment of brain damage and myocardial damage.For the treatment of PCAS,early therapeutic hypothermia,glucose control and seizure control,and reasonable cardiopulmonary support are promoted.In this article,we reviewed the advances in the above fields and the latest advance on the management of PCAS in foreign countries.

Objective To analyze the mierosurgery treatment and prognosis of cavernous hemangioma loca-ted in pons. Methods 12 cases with cavernous hemangioma located in ports underwent mierosurgery. 11 lesions lo-cated in dorsal tons were resected through midline suboccipital trans- rhomboid fnssa approach. 1 lesion located in ventrolateral pous was resected with suboceipital retrosigmoid approach. Results All the 12 cavernous hemangiomns were rosected totally and confirmed by the postoperative pathology. Clinical improvement was gained in 6 cases, no change in 3 ,aggravation of facial palsy in 1 ,death in 1. The mean follow-up time was 3 months,and Mill scan dem-onstrated good restoration of brain stem tissue with no recurrence signs of lesion. The symptoms due to the operation recovered to some extent. Conclusion The cavernous hemangioma located in brain stem can be resected safely and effectively given the selection of surgical indication and optimal surgical approach.

Objective To investigate the relationship between bone mineral density (BMD) and the changes of serum adiponectin (APN) level in elderly men.Methods A total of 240 elderly men was enrolled in this study.Measurement of BMD of lumbar spine with dual energy X-ray absorptiometry was performed.All subjects were divided into three groups (normal,osteopenia,and osteoporosis) according to the T value of BMD.Serum APN level was tested using enzyme-linked immunosorbent assay (ELISA),meanwhile were recorded as bone lurnover markers.Results (1) The level of serum APN in osteopenia group was lower than in normal group,the level of serum APN in osteoporosis group was significantly lower than in osteopenia group,while the level of serum APN in osteoporosis group was significantly lower than in normal group (all P < 0.05).(2) Serum APN was positively correlated with T value of BMD (r =0.475,P <0.01).(3) The stepwise multiple linear regression analysis showed serum APN,25-hydroxyvitamin D,β-isomerized carboxyterminal propeptide (β-CTX),and osteocalcin could enter into the equation.Conclusions Serum APN might play an important role in pathogenesis of osteoporosis in elderly men.

This study was aimed to optimize bio-solid bidirectional fermentation conditions of Trametes robiniophia Murr. for rhubarb. Sulphuric acid-phenol colorimetry, magnesium-methanol colorimetry, and HPLC were used in the
content determination of polysaccharide, total anthraquinone, and 4 free anthraquinones. The drying rate and con-sumption rate were combined as indicators for the optimization of technical parameters such as medicinal dosage, temperature and amount of water. The results showed that when using 500 mL conical flask, the best fermentation conditions were medicinal dosage of 10 g, the temperature of 34℃, adding water of 120%. It was concluded that bidirectional fermentation of rhubarb increased the content of free anthraquinones. Among them, the content of chrysophanol with anti-oxidation effect increased significantly. The decreasing of combined anthraquinone can relieve the severe laxative effect of rhubarb.

This article investigated the applicability of the near infrared spectroscopy (NIR) technology, combined with the least squares support vector machines (LS SVM) used for the quality monitoring of medicated leaven fermentation. First, near infrared spectra of 67 medicated leaven samples were obtained by near infrared spectroscopy system in the wavelength range of 400 2 500 nm, and then the protease and amylase activity were measured by Folin phenol method and DNS method. Thereafter, the LS SVM was employed to calibrate models. The Rc and Rp of protease in near infrared model were 0.975 and 0.938, respectively; The RMSEC and RMSEP were 5.297 and 9.795, respectively. The Rc and Rp of amylase in near infrared model were 0.987 and 0.973, respectively; The RMSEC and RMSEP were 7.215 and 6.864, respectively. This model has good prediction ability and is suitable for quality monitoring in medicated leaven fermentation process. The research achievement could lay a certain foundation for the near infrared spectral analysis technology applied in the field of traditional fermentation processing.

AIM: To examine the effects of L-carnitine on apoptosis and oxidant injury in cultured neonatal rat cardiomyocytes induced by hypoxia/reoxygenation and its possible mechanism. METHODS: The cultured cardiomyocytes were divided into three groups, control, A/R group (anoxia for 120 min, reoxygenation for 240 min) and L-carnitine treatment group, in which cells were exposed to 20 mg/L, 50 mg/L, 100 mg/L, 200 mg/L L-carnitine respectively at 2 h before anoxia. The superoxide dismutase (SOD), succinate dehydrogenase (SDH) activities and malondialdehyde (MDA) content were examined, and the apoptosis was determined by flow of cytometry (FCM). In addition, the ultrastructure was observed by transmission electron microscopy. RESULTS: In A/R group, SOD and SDH activities were lower, the apoptosis rate and MDA content were higher than those in control group (P

AIM: To examine the effects of L-carnitine on apoptosis in cultured neonatal rat cardiomyocytes induced by hypoxia/reoxygenat ion and its possible mechanism. METHODS: A cell culture model of neonatal rat cardiacmyocytes wa s used. The cultured cardiomyocytes were classified into three groups: control g roup, I/R group (anoxia for 120 min, reoxygenation for 240 min) and L-carnitine group (L-carnitine, which was classified into four different concentrations, was added to the cells 2 h before anoxia).
