Clinical data of 23 elderly patients with rectal cancer undergoing trans-sphincteric local resection(TSLR, Mason's operation)were retrospectively analyzed. All the 23 patients were followed-up for three to seven years after operation, 18 with normal or good fecal continence(78%), five just in fair condition(22%)and none in fecal incontinence. Three-year survival was 83 percent(19/23)and 5-year survival was 78 percent(18/23)for them. It is suggested that TSLR is a safe, feasible and effective treatment for middle and low rectal cancer in the elderly with a long term survival and satisfactory quality of life.

Aim To investigate the influence of down-regulating adenosine A1 receptor and adenosine A2 A receptor gene expression on proliferation and activation of acetaldehyde-induced hepatic stellate cell-T6 cells through siRNA. Methods Alcoholic liver fibrosis in vitro model was constructed by inducing HSC-T6 cells with acetaldehyde. siRNA targeting A1R and A2AR were designed and synthesized according to its mRNA. The siRNA was transfected into rat HSC-T6 cells by li-posome LipofectamineTM 2000. HSC cell proliferation was measured by MTT. The mRNA levels of A1R, A2AR, α-SMA, Collagen I in the supernatant of the cell culture were measured by Quantitative Real-Time PCR. The protein levels of A1R, A2AR, α-SMA, Collagen I were measured by Western blot. Results A1 R and A2 AR siRNA effectively inhibited the cell proliferation, and they also significantly decreased the levels of A1R, A2AR,α-SMA, Collagen I, suggesting that A1 R and A2 AR might be potential target genes in the alcoholic liver fibrosis. Conclusions Silencing A1 R or A2 AR by RNAi can significantly inhibit the HSC proliferation, A1R and A2AR may be potential therapeutic target genes for alcoholic liver fibrosis.

Objective To discuss the value of combining superselective mesenteric angiography (SSMA)with methylene blue in-jection for localization of the Obscure Gastrointestinal Bleeding (OGIB).Methods 12 patients presenting with OGIB had preopera-tive localization of the bleeding site by SSMA.The microcatheter was remained inside the bleeding artery branch after angiography. Then the methylene blue was injected via the microcatheter for localization during exploratory laparotomy and the dyed intestine was then removed.Results The detected rate of bleeding sites by using preoperative SSMA was 100%.The lesions in total 12 patients were found quickly during the exploratory laparotomy.The length of the removed intestine was 9 -12 cm (median,10 cm).After followed up for 10-24 months (median,18 months),all patients with OGIB had no recurrence.Conclusion The method of SSMA combined with the use of methylene blue injection is a safe and effective procedure for the localization of OGIB and could be beneficial for increasing the surgical success rate of hemostasis.

Objective To report 6 Chinese patients with mitochondrial encephalomyopathy caused by mitochondrial DNA(mtDNA)G13513A mutation and discuss the mitochondrial phenotype associated with this mutation based on the data of our patient series as well as the reports by others.Methods Direct sequencing of polymerase chain reaction(PCR)products or PCR-RFLP analysis Was performed to screen mtDNA G13513A mutation in 35 cases with mitoehondrial encephalomyopathy.who carried no mtDNA common mutations(1arge 8eale deletion,A3243G,T3271 C,A8344G,or T8993G/C).The clinical features,MRI changes were retrospectively collected and analyzed.Published studies of all patients with mtDNA G13513A mutation were also reviewed.Results Six patients were identified carrying mtDNA G13513A mutation.All patients presented stroke-like episodes with hemianopsia.hemiparesis or hemiparesthesia.Three adult patients presented clinical and radiological features of adult-onset mitochondrial myopathy,encephalopathy,lactic acidosis,and stroke-like episodes(MELAS),including stroke-like episodes,epilepsy,headache,short stature,sensorineural deafness,multifocal lesions on parietal,occipital and temporal lobes on cranial MRI scans.Three iuvenile.onset patients presented the clinical and brain MRI features of MELAS-Leigh syndrome(LS)overlap syndrome.In addition to the stroke-like episodes,they also showed brain stem lesions with dysarthria,ataxia,and ophthalmopJegia. Brain MRI revealed asymmetrical lesions in the cortex of the oecipital and temporal lobes,as well as symmetrical lesions in the bilateral basal ganglia and brainstem.Muslce biopsy showed ragged redfibem in 5 patients.The infant-onset LS or Leigh-like syndrome with mtDNA G135 13A was described in the English literature.Conclusions mtDNA G13513A mutation is a common pathogenic mutmion for mitochondrial encephalomyopathy,which can result in Leigh syndrome,MELAS-LS overlap syndrome and adult MELAS.The onset of various phenotypes is relatively age-dependent.

Objective To investigate the relationship between apolipoprotein E(Apo E) gene poly-morphism and mild cognitive impairment (MCI) in patients with type 2 diabetes mellitus (T2DM), and e-valuate the correlative risk factors. Method 40 cases of type 2 diabetes with MCI and 80 cases of type 2 diabetes without MCI were enrolled in this study. The polymorphism of the Apo E gene was detected by PCR-restriction fragment length polymorphism(PCR-RFLP). According to the clinical data such as course of disease, plasma glucose, plasma fat and body mass index (BMI), the independent risk factors of T2DM and MCI were analyzed by non-conditional logistic regression. Results The frequency of Apo E ε_4 allele in the group of type 2 diabetes with MCI was higher than that without MCI ( 25.0% vs 10. 0% ), and the difference had statistical significance( P < 0. 01 ). The indexes of the statistical significant difference be-twcen the two groups were age, course of disease, postprandial blood glucose ( P2BG), HBA1C, BMI,family history of T2DM, hypertension, diabetic retinopathy, diabetic peripheral neuropathy, Apo E gene. The independent risk factors included diabetic retinopathy ( OR = 3. 452, P < 0. 05 ), diabetic peripheral neuropathy( OR = 3. 252, P <0. 05), Ape E gene( OR = 2. 441, P < 0.01 ), HBA1C ( OR = 1. 372, P <0.05), P2BG(OR = 1. 194, P <0.05), age(OR = 1. 194, P <0.01) and course of disease(OR =1. 142, P <0. 05). Conclusion Apo E ε_4 allele has significant relationship with T2DM and MCI. The age, course of disease, control of plasma glucose, and microvascular complication of diabetes have relation-ship with the cognitive function.
