BACKGROUND: Studies have shown that Maca can enhance immune cel function, improve mitochondrial respiratory chain enzymes, and play a role in anti-oxidation and anti-aging.
OBJECTIVE: To observe Maca effects on kidney mitochondrial respiratory function and anti-aging capabilities in elderly rats after exhausted exercise.
METHODS: 10-month-old elderly rats were intragastrical y administrated Maca powder 5 g/kg, once a day, and did treadmil exercise, 5 days in a week. Rats were randomly divided into control group, Maca group and training group and Maca+training group. At 6 weeks after training, rats in each group did exhausted exercise (35 m/min), and immediately received intraperitoneal injection of 2% sodium pentobarbital. The kidney was obtained, and mitochondria were extracted by differential centrifugation. A spectrophotometer was used to measure mitochondrial respiratory chain activity.
RESULTS AND CONCLUSION: (1) Mitochondrial respiratory chain enzyme and antioxidant enzyme activity: mitochondrial respiratory chain enzyme I-III, superoxide dismutase and glutathione peroxidase activities were higher in the Maca+training group than in the control group, Maca group and training group (P < 0.05 or P < 0.01), but malondialdehyde content was lower (P < 0.05 or P < 0.01). (2) Results suggested that the combination of supplement Maca and incremental exercise can improve mitochondrial respiratory function and delay aging in the kidney of aged rats after exhausted exercise. Moreover, supplemented Maca and incremental exercise have a synergistic effect.

Objective To compare the effects of vasopressin and adrenaline on cerebral resuscitation in rats. Method Sixty male SD rats were used to set the animal model of cardiac arrest and were randomly (random number) divided into 4 groups (n = 15/group): sham operation group (sham-gro), negative control group (neg-gro), vasopressin group (vas-gro) and adrenaline group (adr-gro). Blood pressure was recorded, and brain tissue samples were obtained. Results There was no significant difference in the recovery rate between vas-gro and adr-gro 30 min after resuscitation (P ＜0.05). The mean blood pressure in vasgro was higher than that in adr-gro within 30 min (1,2, 5, 10, 20, 30 min) after restoration of spontaneous circulation. The measured MDA, SOD and GSH were significantly different (P ＜ 0.05) between each two groups among vas-gro, sham-gro and adr-gro. Conclusions The recovery rate was similar between vasopressin group and adrenaline group during cardiopulmonary resuscitation in rats. However, vasopressin can to maintain the mean arterial pressure at a higher level after resuscitation, which can the increase the cerebral perfusion and reduce brain cell damage.

Objective To explore the effects of estrogen,sport walking with weight and estrogen plus sport walk on serum lipid,bone metabolism and bone mineral density(BMD) in postmenopausal women.Methods 52 postmenopausal women were divided into the hormone replacement therapy(HRT) group(n=12),sport walking with weight group(Sp group,n=14),HRT + Sp group(n=12) and control group(n=14).HRT group took compound nylestriol,Sp group took sport walking with 5 kg weight and exercise intensity was from 60% to 80% VO2max,HRT+Sp group received two treatments as HRT group and Sp group.The experimental duration consisted of six months.Results The total cholesterol(TC),TC/high density lipoprotein cholesterol(HDL-C),alkaline phosphatase(APL) and urine calcium(Ca)/creatinine(Cr) were markedly lower in three experimental groups than the control group and before experiment(P<0.05 or P<0.01),HDL-C in Sp and HRT+Sp groups were markedly higher than the control group and before experiment(P<0.05),BMD of spine(L2～L4) and left trochanter in three experimental groups were markedly higher than the control group(P<0.01) and before experiment(P<0.0).Conclusion Both estrogen replacement therapy and sport walking with weight effectively improve serum lipid,prevent and reverse osteoporosis induced by menopause in women.

Sinus osteoma is a common nasal and sinus disease, while the clinical cases of osteoma with a diameter greater than 30 millimeter are rarely seen. This paper reports a case of a 39-years-old male patient discovered with one-year long swelling pain in the right eye. The patients' right eye was mildly prominent and he suffered from hypopsia and diplopia. After CT scanned, he have ethmoid osteoma been discovered, besides, the right media rectus compression and orbital apex compression and consequent pathologically were diagnosed. The solid tumor ranged widely from the anterior skull base to the superior and interior orbital walls,and thus deprived the patient's complete surgical resection. As an attempt to prevent complications, most parts of the tumors were sur gically removed.

Viral infection begins with the entry of the virus into the host target cell and initiates replication.For this reason,the virus entry machinery is an excellent target for antiviral therapeutics.In general,a virus life cycle includes several major steps: cell-surface attachment,entry,replication,assembly,and egress,while some viruses involve another stage called latency.The early steps of the virus life cycle include virus attachment,receptor binding,and entry.These steps involve the initial interactions between a virus and the host cell and thus are major determinants of the tropism of the virus infection,the nature of the virus replication,and the diseases resulting from the infection.Owing to the pathological importance of these early steps in the progress of viral infectious diseases,the development of inhibitors against these steps has been the focus of the pharmaceutical industry.In this review,Herpes Simplex Virus(HSV),Hepatitis C Virus(HCV),and Human Enterovirus 71(EV71)were used as representatives of enveloped DNA,enveloped RNA,and non-enveloped viruses,respectively.The current mechanistic understanding of their attachment and entry,and the strategies for antagonist screenings are summarized herein.

Objective To discuss the correlation between plasma homocysteine (Hcy) and diabetes and pre-diabetes.Methods Participants included 115 patients with diabetes,150 patients with abnormal glucose tolerance diagnosis for pre-diabetes and 131 cases without blood glucose abnormalities crowd as control.All the basic informations of the subjects were recorded detailedly.Multiple factors regression analysis was completed.Results Development of diabetes single factor correlation analysis result showed that history of hypertension,hyperlipidemia,body mass index (BMI) ≥ 24 kg/m2,high Hcy were positively correlated with development of diabetes,and life rules was negatively correlated with development of diabetes (P ＜ 0.05 or ＜ 0.01).Development of diabetes multiple factors correlation analysis result showed that history of hypertension,hyperlipidemia,BMI ≥ 24 kg/m2,high Hcy were the independent risk factor for development of diabetes (P ＜ 0.05).Development of pre-diabetes single factor correlation analysis result showed that hyperlipidemia,BMI ≥24 kg/m2,high Hcy were correlated with development of pre-diabetes (P ＜ 0.01).Development of pre-diabetes multiple factors correlation analysis result showed that hyperlipidemia,BMI ≥ 24kg/m2,high Hcy were the independent risk factor for development of pre-diabetes (P ＜ 0.05).Conclusions Plasma Hcy is intimate correlated with diabetes and pre-diabetes,and it is an independent risk factor for development of them.In clinical work,the patients with high Hcy need to give the necessary intervention.
