Objective To investigate the effect of radix paeoniae rubra (RPR) on expression of heme oxygenase (HO-1) and inducible nitric oxide synthase (iNOS) in lipopolysaccharide (LPS)-induced acute lung injury (ALI) and explore its protective mechanism. Methods Forty Wistar rats were randomly and equally divided into five groups, ie, control group, LPS group, RPR treatment group, RPR prevention group and Hemin group. Arterial blood was drawn for blood gas analysis. Models of endotoxin-induced ALI were used to observe the protein content, the ratio of neutrophiles in bronchoalveolar lavage fluid (BALF), the malondialdehyde (MDA) content in lung and the activities of serum NO. Expression of HO-1 and iNOS in rat lung tissue was detected by immunohistochemistry and morphometry computer image analysis. The histological change of lung were observed under light microscope. Results Compared with control group, expression of HO-1 and iNOS was markedly increased (P

The origin, branching and distribution of the superior mesenteric artery were observed on 100 Chinese adult cadavers. The average level of the origin of the superior mesenteric artery lay on the middle third of the body of the first lumbar vertebra. The distance between the origins of the superior mesenteric artery and the coeliac artery and the diameter of the superior mesenteric artery were measured. The superior mesenteric artery usually gave off two (47％) or three (39％) colic branches. The relationships of the origin of each colic branch, originating directly from the superior mesenteric artery, to the third part of duodenum or the head of pancreas and also to the origins of the intestinal arteries were observed. The extent of distribution of each colic branch was estimated. Most of the superior mesenteric arteries (82％) did not distribute so far as the left colic flexure. The pattern of branching of the ileocolic artery may be divided into four types. The symmetrical and ansal types were the prevailing types, they were present in 45.26％ and 42.11％ respectively. Nearly half of the appendicular arteries (45.56％) arose from the ileocolic artery, about 34.44％ appendicular arteries arose from the ileocolic ansa. Usually the appendicular artery was the first branch of the ileocolic trunk. The superior mesenteric artery gave off 15.9 intestinal branches in average. In 76％ cases, the inferior pancreatic-duodenal artery and the first intestinal artery originated from a common trunk and this trunk usually arose from the posterior aspect of the superior mesenteric artery. We found that in 13 cases the superior mesenteric artery gave off common hepatic artery or right hepatic artery.

Sperm associated antigen 9(SPAG9),a new member of the c-Jun NH2-terminal kinase (JNK)interacting protein(JIP)family. plays a role in sperm-egg fusion and mitogen-activated protein kinase (MAPK)signaling pathway.Researches have shown that SPAG9 is closely related to the biological behavior of human malignant tumors, and plays an important role in the development of tumor.

ObjectiveTo discuss treatment experiencing in femur periprothetic fracture after hip arthroplasty in pre-, intra- and post-surgery.Methods From March 2005 to May 2011, 27 patients (11 males, 16 females) aged ＞75 years with femur periprothetic fracture after hip replacement were studied. The mean time from primary hip replacement to femur perprosthetic fracture was 63 months(ranging from 7 to 83 months). According to vanconver classification, type A applying steel wire of character for 8 bind technique was 5 cases, type B applying prolonging stem technique locking compress plate (LCP)technique surrounding instrument technique was 19 cases and type C applying bone graft and plate fixation technique was 3 cases. All patients were followed up from 9 to 25 months (average, 16 months). The results of treatment were evaluated by Harris score and X rays. Results Bony heal was obtained in 22 patients and was not obtained in five cases among whom bony heal occurred in 3 cases and 2 patients could only keep prothetic and limb stable after receiving the bone graft once more. Walking was free in 14 cases,9 cases needed assistant walking instrument,and only 4 cases stayed in the bed freely. Harris score for last follow-up was 52 to 93 (mean 76).Conclusions Based on the patient general status, the fracture types and practical and stable principle, the effective methods can get good results in the treatment of femur periprosthetic fracture in aged patient.

C3 glomerulopathy (C3G) is referred to disease which is out of control of complement activation,degradation and deposition,then leads to predominant C3 deposition in glomerular and glomerular injury.The study found that C3b amplification in the circulation and/or glomerular basement membrane were the key factors that cause immune disorders.Combined with clinical and experimental research,this paper mainly discusses the pathogenesis,clinical characteristics,and treatment of the disease.

Objective To investigate the changes and relationships between the serum endogenously produced interleukin-10(IL-10),nitric oxide synthase(NOS) and inducible nitric oxide synthase(iNOS) in acute myocardial ischemia and reperfusion.Methods Forty-two rats were randomly divided into two groups: myocardial ischemia and reperfusion group(the control group) and methylprednisolone treatment group.The rats in the control group and methylprednisolone treatment group received intravenous injection of placebo and methylprednisolone before ischemia respectively.The plasma IL-10,NOS and iNOS were detected at 0.5 h after ischaemia and 0.5h,2 h after reperfusion,respectively.Result The plasma IL-10,NOS and iNOS gradually increased at 0.5 h after ischaemia and 0.5h,2 h after reperfusion in the two groups.The levels of plasma IL-10 were significantly higher in the methylprednisolone treatment group in different time points than those in the control(all P

Many tumor cells are resistant to cell apoptosis through the expression of antiapoptotic proteins. c-FLIP is a ma-jor resistance protein of antiapoptosis. In human cells, there are three types of c-FLIP, c-FLIPL , c-FLIPS and c-FLIPR . The c-FLIP binds to FADD to prevent the formation of procaspase-8-DISC and the subsequent activation of caspase cascade. Further-more, c-FLIPL and c-FLIPS have multifunctional roles in various cellular signaling pathways, as well as up-regulating several cyto-protective signaling. Studies show that upregulation of c-FLIP has been found in various tumors, and its downregulation has been shown to restore apoptosis triggered by various chemothera-peutic agents, like the transcriptional regulating agents, trichos-tatin-A, camptothecin, cisplatin, doxorubicin, etc. or other new biotechnologies, such as the specific siRNA. Therefore, c-FLIPS are important targets of cancer therapy. This review summarizes the results on the role of c-FLIP in cancer chemotherapy of tradi-tional antitumor agents and siRNA, and to provide new ideas and rationales of searching for the antiapoptosis effective compounds that can specifically antagonize c-FLIP.

Objective To explore the effects of penehyclidine hydrochloride (PHC) on the withdrawal syndrome and conditioned place preference(CPP) of morphine dependent rats. Methods ( 1 ) Forty-eight male SD rats were randomly assigned to 6 groups with one of 8 rats:morphine dependent group (MOR group) ,naloxone precipitated withdrawal group ( NAL group) ,PHC treatment groups ( PHC1,2,3 ) ,normal saline control group ( NS group). Subcutaneous injection of morphine in gradually increasing doses for 5 days (from 10 to 50 mg/kg ,two times daily) to establish the model of morphine physical dependent rats. The withdrawal syndrome was precipitated by naloxone (5 mg/kg,sc) and treated with PHC in various doses (0.5,1.0,1.5 mg/kg ,ip ) 30 min before haloxone-precipitated withdrawal. The body weight loss and withdrawal syndrome were observed respectively in 20 minutes. (2) 40 male SD rats were randomly assigned to 5 groups with one of 8 rats: morphine dependent group (MOR group) ,PHC treatment groups (PHC1 ,2,3 ) ,normal saline control group (NS group). The morphine conditioned place preference was induced by alternate subcutaneous injection of morphine for 7 days in rats ( 10mg/kg,once daily,8:00 AM) and saline( 16:00 PM). At d8,the rats were received the CPP test. The rats of PHC groups were treated with PHC (0.5,1.0,1.5 mg/kg , ip) prior to the CPP test, whereas the rats were treated with saline in MOR and NS group. Results (1) Theweight loss((8.53 ±l.20)g,(7.36±l.06)g,(5.40±1.79 ) g vs ( 12.63 ± 2.22 ) g, F = 83.16, P ＜ 0.01 ) and score precipitated withdrawal symptoms ( 25.36 ± 3.11,21.38±3.50,17.06±1.78 vs 31.69 ±2.76, F=256.56, P＜0.01)of morphine withdrawal rats was obviously alleviated by ip PHC in dose-related manner before naloxone-precipitated withdrawal. (2) There were significant differences in the times spent in the drug-paired side (gray area) between MOR and PHC groups( (529 ± 83 )s,(460 ± 107 ) s, (418 ± 97 ) s vs ( 643 ± 111 ) s, F = 13.22, P ＜ 0.01 ), and also in dose-related manner. Conclusion PHC could significantly inhibit the withdrawal syndrome and the expression of CPP on morphine dependent rats in a dose-dependent manner.
