Prostate cancer is one of the common malignant tumors of the urinary system and mostly found in elderly men. Like most tumors, prostate cancer involves a variety of molecules in its occurrence and progression. More studies on the development of prostate cancer focus on the tumor markers, DNA damage repair related genes, and tumor invasion and metastasis related factors. This article presents an overview on the research progress in these three aspects.

Vascular cognitive impairment (VCI) is a main type of syndrome from mild cognitive impairment to dementia,which is caused by cerebrovascular risk factors (eg,hypertension, diabetes,hyperlipemia),obvious (cerebral infarction and hemorrhage) or unobvious cerebrovascular disease (leukoaraiosis and chronic cerebral ischemia).Its incidence is increasing,however,its pathogenesis remains uncertain,and effective therapeutic tools are lacking.Therefore,an increasing attention is being paid to all aspects of studies.This article mainly reviews the recent development in research of neuropsychology,imaging,electrophysiology,biology,and gene.

NF-?B, a group of important transcription factors, are introduced and discussed here on several aspects: their component and molecular structure; their activity control by I?B and IKK, the mechanism of their activation; their important roles in transcriptional regulation for large numbers of genes; and their importance in immunity, inflammation, cell survival, proliferation and apoptosis. The analysis of the relation between NF-?B and disease occurrence, the analysis of the relation between NF-?B and disease therapy, and the application prospect of the new strategy regarding the novel drug design and correlative diseases therapy on the basis of NF-?B as the target, are also included.

Objective · To investigate the prevalence of passive smoking among pregnant women in Shanghai and to analyze its influencing factors and to provide the basis and suggestion for making related intervention measures to reduce the harm of secondhand smoke on the health of pregnant women. Methods · From July to October 2014, pregnant women and their spouses were recruited for a questionnaire investigation at the antenatal care clinics of 3 maternity hospitals and 3 community hospitals in Shanghai. The questionnaire included demographic information, family basic situation and cognitive status of passive smoking. Results · The passive smoking rate before pregnancy in the 2831 pregnant women, who were involved in the investigation, was 17.1%. The passive rate during pregnancy was 7.8%. The difference between these two rates was statistically significant (P<0.05). 71.0% of the pregnant women have passive smoking for 15~59 min each day. Relative to home and work place, the passive smoking rate of pregnant women in public place was the highest (P<0.05). The passive smoking rate of pregnant women was significantly associated with the educational level of smoking spouses and the attitude of pregnant women when they faced the smokers. Conclusion · The passive smoking rate of pregnant women is influenced by the educational level of their spouses and the pregnant women's feedback to the smokers face to face. Public places are the most important exposure places to secondhand smoke for pregnant women. In order to reduce the harm from passive smoking to pregnant women and their fetuses, the related measures of smoking control at home education and smoking ban in public place should be made.

Ten glycosidic compounds were isolated from an ethanol extract of Machilus wangchiana by a combination of various chromatographic techniques including column chromatography over silica gel and Sephadex LH-20 and reversed-phase flash chromatography and HPLC. Their structures were identified by spectroscopic data analysis (IR, MS, and NMR) as icariside B1 (1), boscialin-3-O-β-D-glucopyranoside (2), pisumionoside (3), isolariciresinol-9'-O-β-D-xylopyranoside (4), 5'-methoxyisolariciresinol-9'-O-β-D-xylopyranoside (5), lyoniresinol-9'-O-β-D-xylopyranoside (6), (E) -4-hydroxyphenylprop-7-ene 4-O-β-D-glucopyranoside (7), (E) - 4-hydroxy-3-methoxyphenylprop-7-ene 4-O-α-L-rhamnopyranosyl-(1 --> 6) -β-D-glucopyranoside (8), 4-hydroxy-3-methoxyphenylprop-8-ene 4-O-β-D-xylopyraosyl-(1 --> 6) -β-D-glucopyranoside (9), and 4-hydroxy-3,5-dimethoxyphenylprop-8-ene 4-O-α-L-rhamnpyranosyl-(1 --> 6)-β-D- glucopyranoside (10), respectively.

ObjectiveTo share the experience of arterial plasty and reconstruction of variant arteries in living donor liver transplantation. MethodsFrom September 2006 to May 2010, 73 living donor liver grafts (64 cases using the right lobe,9 cases using left lobe) were used in patients with end-stage liver disease. The hepatic arteries were evaluated preoperatively with computed tomography and magnetic resonance angiography. Back-table arterial plasty was performed under a microscope or a loupe according to arterial variation. We described technical points based on anatomic variations. There were 13 (17. 8 ％) liver grafts with anatomic hepatic arterial variations and all of these cases were subjected to back-table reconstruction with interrupted 8-0 or 9-0 nonabsorbable nylon monofilament sutures according to the diameter of artery. ResultsIn 3 cases, the associate right hepatic arteries that were arisen from superior esenteric arteris (SMA) were reconstructed to cystic arteries. In 2 cases with the associate right hepatic arteries arisen from the abdominal trunk, the right hepatic arteries and associate right hepatic arteries of donors were anastomosed with right hepatic arteries and left hepatic arteries in recipients respectively. In 2 donors, hepatic arteries had branches, which were reconstructed. All of the arterial plasty were conducted on a back table. No arterial thrombosis was found during a postoperative follow-up period of 6 months. ConclusionLive donor liver transplantation using the right lobe with hepatic artery variation can be performed safely, but there is a potential operative risk of severe complication after transplantation. Tominimize operative difficulties and complications, back-table reconstruction should be applied and proper treatment is given according to individual situations to ensure a safe and satisfactory outcome

AIM: To investigate the role of staphylococcal enterotoxin B (SEB) in early intestinal injury in scald rats with Staphylococcus aureus sepsis. METHODS: 86 male Wistar rats were randomly divided into four groups as follows: normal controls ( n= 10), scald control group( n= 10), postburn sepsis group( n= 50) and SEB monoclonal antibody (MAb)treatment group ( n= 16). Plasma samples were collected to determine SEB, endotoxin, tumor necrosis factor-? (TNF-?) and interferon-? (IFN-?). RESULTS: After scald injury followed by Staphylococcus aureus challenge, the levels of SEB, TNF-? and IFN-? in plasma were significantly higher than those of normal controls, peaking at 2-6 h ( P

The evidence and the feature of apoptosis following tyrauma brain injury(TBI) and the possible mechanisms underlying apoptosis were reviewed. Recently research showed that apoptosis play an important role in TBI, the occurring time and area of apoptosis were found significant differences compared with that of necrosis. The neural cell apoptosis can undergo following many pathways after TBI. In our review, the foreground of apoptosis after TBI research in forensic pathology were also discussed.
