Objective: To study the effect and possible mechanism of Ginsenoside Rg1 in sports CNS fatigue and dose-response relationship.Methods: Kun Ming male mice were divided randomly into 6 groups: control group and five different doses groups(5,10,20,40,80 mg/kg).They were treated orally with Ginsenoside Rg1 for 2 weeks.The levels of amino acids of brain tissue were tested after swimming for 90 min and the exhaustive swimming time were recorded.Results: The levels of BCAA and the ratio of BCAA/AAA in groups 5,10 and 20 mg/kg were significantly higher than control group and the levels of AAA in groups 5,10,20 and 40 mg/kg were significantly decreased.The exhaustive swimming time in groups 5,10 and 20 mg/kg were much longer than in control group.Conclusion: Through adjusting the ratio of BCAA and AAA and decreasing the level of excitatory amino acids neurotransmitter,Ginsenoside Rg1 can elevate movement ability and resist against CNS fatigue.The roles of mid-low and low doses may be better.

Objective To investigate the effects of lipopolysaccharide(LPS) on the tryptophan-kynurenine(TRP) metabolic pathway in rat brains and provide new evidence for the relationship between inflammation and depression.Methods Rats in LPS group were given a single dose of 3.5 mg/kg LPS.while the rats in control group were given the same dosage of saline.The dialysis in ventro-hippocampus were collected by microdialysis within 8 hours and then the TRP,KYN and KA were detected by LC-MS/MS.And the expression of indoleamine 2,3-dioxygenase was detected by Western-blot.Results The level of TRP((550.15± 107.96) pmol/L) and KYN ((337.95±62.73) pmol/L) showed a time-dependent increase after administration LPS 4 h compared with the control group(TRP (368.38±59.31) pmol/L,KYN (172.80±43.96) pmol/L),while KA level in the circulation exhibited a trend to decrease,especially at 7 h ((3.47±0.62) pmol/L,P＜0.05).The ratio of KYN/TRP significantly increased at about 5 h (0.69±0.11,P＜ 0.05),and an ratio of KA/KYN (0.02±0.00) was dramatically decreased after administering LPS 4 h compared with the control group (0.05±0.01)(P＜0.05).Most of the analytes showed more dramatic changes around 4 h to 8 h.LPS group(1.48±0.37) increased the protein expression of indoleamine 2,3-dioxygenase compared with the control group(1.00±0.24) (P＜0.01).Conclusions LPS may cause tryptophan metabolic abnormalities and accelerate the way of kynurenine metabolism,leading to decreased the kynurenic acid status.

Iatrogenic gastrointestinal perforation is one of the severe adverse events of endoscopic therapeutic procedure. For acute iatrogenic perforation,management by endoscopic techniques is a simple and rapid modality to close the perforation with minimal invasiveness and avoiding the traditional surgical trauma. Endoclips,suture with special instruments,covered stents,degradable sheets combined with tissue adhesive,and combined endoscopic techniques such as snares combined with endoclips,are the major endoscopic therapeutic modalities for closure of iatrogenic gastrointestinal perforation. In this article,the current status and progress of endoscopic management for acute iatrogenic gastrointestinal perforation were reviewed.

BACKGROUND: Pancreas-kidney transplantation is an effective treatment for diabetes combined with final stage renal disease. However, as the patients suffer diabetes for a long period of time, and cardiovascular system disease is complex, pre- and post-transplantation treatment is very important for successful pancreas-kidney transplantation.OBJECTIVE: To discuss immunosuppressant, coagulant, perioperative and postoperative treatment during pancreas-kidney transplantation to provide some clinical experience for pancreas-kidney transplantation.METHODS: Clinical data of 5 cases undergoing simultaneous pancreas-kidney transplantation in Department of Urinary Surgery, the 309 Hospital of Chinese PLA General Hospital between 2003 and 2008 were retrospectively analyzed to summarize the application of immunosuppressants and anticoagulant drugs and perioperative clinical monitoring focus. RESULTS AND CONCLUSION: There were 5 male patients with an average age of 43 years, and suffered type I diabetes mellitus complicated with final stage renal disease. The preoperative insulin dosage was 1.5-2.4 U/(kg·d). One case had diabetic retinopathy and fundus oculi hemorrhage for many times; two cases showed apparent coronary atherosclerotic heart disease with preoperative cardiac ejection fraction of 52% and 50%. Exocrine of transplanted pancreas had been considered by the intestinal fluid drainage. A total of 3 cases were complete rehabilitation. Of them, 1 case developed acute rejection in the first seven days after operation, but renal function restored with the hormones impact; 1 case had postoperative acute rejection of transplanted duodenum as well as intestinal fistula, eventually, transplanted pancreas was ectomized, but transplanted kidney was preserved; two cases succeeded in restoring and no complications occurred; 1 had postoperative gastrointestinal bleeding and died from multiple organ failure. Simultaneous pancreas-kidney transplantation is the most effective way to treat the diabetes mellitus with terminal nephropathy. Because of complications in the transplanted exocrine pancreas with bladder drainage, it has been replaced by the enteric drainage. Recovery of the transplanted kidney function is important for successful transplantation. After operation, oral FK should be taken when the serum creatinine returned to 300 umol/L. The application of clotting drug is one of the important factors for recovery of transplanted pancreatic function. Jejunostomy is an important therapeutic measure to prevent the reflux of intestinal juice to the transplanted pancreas in perioperative period. In the follow-up period cathartic drugs are recommended to prevent constipation and reduce the occurrence of acute pancreatitis caused by intestinal fluid reflux.

OBJECTIVETo explore the pattern of abnormal skeletal development in girls with idiopathic precocious puberty (IPP) and the therapeutic effect of Chinese herbs for nourishing yin and purging fire (CH).

METHODSMeasurement of bone age, bone mineral content (BMC) and bone density (BD) were performed and levels of serum gla-protein (BGP), insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein 3 (IGFBP3) were determined in girls with IPP at various stages of pubertal development. Data were compared with those collected from matched girls, and the correlativity between various parameters and the extent of the disease were analyzed to explore the pattern. Thirty-eight girls out of them were treated with CH and the therapeutic effect was observed.

RESULTSThe bone age of the IPP girls was ahead of time obviously (P < 0.05), levels of BMC, BD and serum BGP, IGF-1 were significantly higher than the levels in the healthy girls of matched age (P < 0.05). And the degree of these changes were markedly positive correlated with the severity of disease (P < 0.05). After being remitted with CH treatment, the advanced bone age was apparently alleviated, and above-mentioned abnormal criteria were lowered significantly (P < 0.05).

CONCLUSIONThe skeletal development of the girls with IPP was accelerated and the skeletal maturity were ahead of time, the more serious the condition of disease, the more obvious the acceleration and the advanced bone age. CH could decelerate skeletal development and delay the skeletal maturity of IPP patients.

OBJECTIVETo investigate the role of environmental endocrine disruptors (EEDs) in causing the precocious puberty.

METHODSThe blood samples were collected from 79 cases of precocious puberty patients and 42 cases of normal children. The concentrations of 4-nonylphenol (4-NP), 1, 1-dichloro-2, 2, bis (p-chlorophenyl) ethylene (p, p'-DDE) and di-2-ethylhexyl phthalate (DEHP) in blood serum samples were measured by using reversed-phase high performance liquid chromatography (HPLC). The volume of uterus and ovary, the bone density, and the content of estradiol (E(2)) in serum were determined at the same time. The contents of EEDs in blood serums of precocious puberty and the indices of the target organs were analyzed by using of correlation and regression.

RESULTSIn normal control group, p, p'-DDE was detected in all the blood samples (14.93 - 40.39 ng/ml), but 4-NP and DEHP were detected in some samples (ND -6.77 ng/ml, ND -17.61 ng/ml). The levels of 4-NP, p, p'-DDE and DEHP in blood serum in precocious puberty group were notably increased than that in control group (P < 0.01). In precocious puberty group, there was a positive correlations between the 4-NP in volume of uterus and the volume of ovary and the density of bone (r = 0.394, 0.286, 0.237, P < 0.01); p, p'-DDE and volume of uterus also showed a the positive correlation (r = 0.306, P < 0.01). The influencing extent of 4-NP was 1.3 times to that of the p, p'-DDE.

CONCLUSIONThe normal children and the children with precocious puberty should be all contaminated by EEDs, and the later be exposured to more EEDs. There might exist a close relationship between EEDs and the precocious puberty, and EEDs should be an important factor in causing the disease. Different kinds of EEDs might have different influencing extents to the target organs.

An autopsy case of sudden death induced by alimentary tract hemorrhage was presented, which was caused by the unexpected rupture of clinically unrecognized tuberculous abdominal aortic a-neurysm (TAAA). The initial diagnosis was made of the syndrome of coronary heart disease and hyper-tensive disease. The detailed autopsy showed that the alimentary tract hemorrhage was caused by a sud-den rupture of the mass after posture changing was ascertained as the cause of death. The diagnosis of TAAA was determined by the autopsy findings. Analysis for the medical dispute of TAAA was de-scribed, and the difficulty of the diagnosis and medico-legal implications were also discussed.
