Objective To investigate the surgical approach of the reasonable radical resection for carcino-mas of pancreatic head. Method 35 of 110 patients with carcinomas of pancreatic head underwent the surgical ap-proach of the posterior aspect of the radical resection for carcinomas of pancreatic head, and histopathological findings and prognosis were analyzed. Results The rate of curative resection rate was 31.82%. 3 patients underwent pancre-atoduodenectomy with partial resection of SMV for 9 patients with macroscopic suspicion of invasion of the SMV. The survival rate of the 5 years was 17.14% and the patients exceed 10 years. Conclusion Surgical approach of the reasonable radical resection for carcinomas of pancreatic head allows the reasonable radical resection,and may lead to increasing the resectability rate and the prognosis in the patients with carcinomas of pancreatic head.

Cardiovascular disease in peri-menopausal period is a kind of climacteric syndrome which based on the symptoms of the cardiovascular system as the main manifestations. It is manifested as hypertension,pseudo-angina,arrhythmia. Hormone replacement therapy or symptomatic treatment is the common used method of modern medicine,although a certain degree of efficacy,but there are also significant disadvantages. In the treatment of cardiovascular disease in peri-menopausal period,TCM has certain advantages. In this paper,we treat cardiovascular disease in peri-menopausal period from the theory of 'yin deficiency,blood stasis,heat-toxin'and propose the method of 'nourishing yin,promoting blood circulation and detoxification'.

Objective To study the relationship between the expression of ICAM-1,HLA-DR in the renal allograft of chronic rejection. Methods The expression of ICAM-1 and HLA-DR was assessed in 20 cadaveric renal allografts with chronic rejection using immunohistological techniqu(ABC method). Results In the renal allograft with chronic rejection,the expression of ICAM-1 was increased on the tubular epithelial cells and interstitial microvascullar endothelium,whereas the expression of HLA-DR was up-regulated,especially on the distal tubules. In addition, the expression of ICAM-1 and HLA-DR was associated with lymphcytes infiltration in the local perivascullar and intertubular structure. Conclusions It is suggested that the increased ICAM-1 and HLA-DR expressions might mediate allograft injury and have a role in the augmentation of the response,either in its induction,especially in the interstitial lymphocytes infiltration and antigen presenting or as a target for the effector arm of the reaction.

Objective To explore ihe physiological changes of the late-onset depressive(LOD) persons during sleep.Methods 15 cases of LOD patients formed a group and 10 healthy aging persons formed a control group.Hamilton Depression Scale (HAMD) was used to score the severity of depression and polysomnographic recorders were used to monitor the whole night long.The subjective feelings of the sleep and the daytime mental status were assessed in the morning.Results Compared with the controlde group, the LOD patients obviously possessed a disordered sleeping process: sleep efficiency was lower( ( 59.20 ± 2.90 ) %, ( 77.09 ± 1.55 ) %, P ＜0.01 ); their sleep latency was longer( (54.00 ± 4.97 ), ( 24.00 ± 2.91 ), P ＜ 0.01 ); the numbers of rapid eye movement(REM) sleep phase and rapid eye movement latency(REML) were strikingly different(P＜0.01 ).Compad with the control group, the LOD patients' awakening time and percent were significantly increased.Not only were the time and percentage of S2 sleep phase much higher, but the time of slow wave sleep was shorter.Besides,REM sleep activity, its density, and its intensity were raised (P ＜ 0.05 ).Conclusion There is a disturbance of the objective physiological indexes happening among the LOD patients.The increase of S2 sleeping time and percentage and the disinhibition of REM sleep can be used as the diagnosis indexes of LOD patients' specificity.

Objective To observe the efficacy and adverse effects of conventionally fractionated (CF) versus hypofractionated (HF) three-dimensional conformal radiotherapy (3DCRT) for hepatocellular carcinoma (HCC) with portal vein tumor thrombosis.Methods A retrospective analysis was performed on the clinical data of 65 patients with HCC suitable for 3DCRT from 2008 to 2012.These patients were randomly divided into HF group (n =32) and CF group (n =32).The HF group received 3DCRT at a total dose of 45-55 Gy (3-4 Gy/fraction,3-5 fractions/week),while the CF group at a total dose of 40-56 Gy (2 Gy/fraction,5 fractions/week).Results The follow-up rate was 100％.For the HF group and CF group,the short-term response rates were 72％ vs.55％ (P =0.034),the 1-year local control rates were 72％ vs.55％ (P=0.034),the 1-year overall survival rates were 59％ vs.45％ (P=0.042),and the numbers of individuals with grade 1-2 acute gastrointestinal reactions,deterioration of liver function,and radiation hepatitis were 14 vs.11,8 vs.8,and 1 vs.0,respectively (P =0.237).Conclusions HF 3DCRT is superior to CF 3DCRT in the treatment of HCC.

Alzheimer's disease(AD)and Parkinson's disease(PD)are common neurodegenerative diseases that seriously threaten the health of the elderly, involving various abnormalities in physiology and metabolism including the impairment of mitochondrial function, Ca 2+ homeostasis deregulation, oxidative stress, aggregation of misfolded proteins, autophagy and inflammation.However, mechanisms underlying the pathogenesis of these diseases have not been clearly elucidated, thus impeding advances in their treatment.In recent years, it has been found that mitochondria-associated endoplasmic reticulum membranes(MAM)play an important role in the development of AD and PD and exert their effects by regulating the functions of mitochondria and endoplasmic reticula.This article reviews studies of the past decade related to the effects of MAM on AD and PD, aiming to generate insights for exploring the constituent proteins of MAM and the molecular mechanisms of AD and PD via endoplasmic reticulum-mitochondria Ca 2+ transport and ER stress regulated by MAM.
