Autophagy contributes to the pathology of various neurodegenerative conditions.Rapamycin,an agent against Candida albicans or immunosuppressive,was found to be effective against tumor.Furthermore,it also induces autophagy by inactivating the protein mammalian target of rapamycin(mTOR),FKBP and VMP1,thus could offer a tractable therapeutic agent for neurodegenerative diseases.

OBJECTIVETo report the experiences of the diagnosis and treatment of primary lymphoma of the small intestine (PSIL).

METHODSThe clinical data of 15 patients with PSIL treated from January 2003 to July 2007 was investigated retrospectively. Of the 15 cases, 9 patients were male and 6 were female, the average age was 51.6 years (range, 18 - 73 years). Data of gender, age, clinical manifestation, laboratory examination, imageology examination, diagnosis and treatment of the patients was reviewed.

RESULTSThe most common clinical manifestations were as follow: abdominal pain, abdominal lump, bowel obstruction, gastrointestinal hemorrhage and athrepsy. Serum tumor markers were checked normal. All the 15 cases were found with tumor by spiral CT, and 12 cases were diagnosed as PSIL. Eleven cases were given Ba-meal examinations, and positive results was found in 4 cases, and only 1 case was considered to be PSIL. All the 15 patients received operation. All the patients were diagnosed as non-Hodgkin lymphoma (NHL) by postoperative pathology (8 patients as diffuse large B-cell lymphoma, 5 as mucosa associated lymphoid tissue type B cell lymphoma and 2 as enteropathy-type intestinal T cell lymphoma). No perioperative death occurred. Ten patients received adjuvant chemotherapy with the regimen of CHOP (cyclophosphamide + epirubicin + vincristine + prednisone) after the operation. Fourteen cases were followed-up for a mean time of 30 months (range, 6 - 52 months). The 1- and 3-years survival rate was 85.7% and 57.1%, respectively.

CONCLUSIONSPSIL has no specific clinical manifestations, the diagnostic rate with barium study is low, spiral CT scan is a promising diagnostic method for PSIL. Operation combined with chemotherapy is important for PSIL.

Objective To accurately judge the tumor-feeding artery is the most important basis for a successful treatment of hepatocellular carcinoma (HCC) with super-selective hepatic arterial chemoembo lization therapy. This study aims to assess the clinical value of cone-beam CT hepatic arteriography (CBCT-HA) in detecting tumor-feeding arteries during the performance of conventional transarterial chemoembo lization (TACE), and to compare the diagnostic effects between CBCT-HA and non-selective hepatic DSA. Methods Twenty-three consecutive patients with inoperable HCC were enrolled in this study. TACE was carried out in all patients. During the performance of TACE, the DSA-HA, CBCT-HA, Lipiodol-TACE and Lipiodol-CBCT were performed separately. The imaging materials, including DSA-HA and CBCT-HA, were analyzed by two experienced interventional physicians together to judge the tumor-feeding arteries. Statistic analysis was conducted by using chi square test. Results Tumor stain and lipiodol accumulation were regarded as the “gold standard” of the presence of tumor-feeding artery, based on which the tumor-feeding artery was confirmed in 75 lesions. DSA-HA demonstrated positive tumor-feeding artery in 40 lesions, among which true-positive tumor-feeding artery was seen in 32 and false-positive one in 8. CBCT-HA showed positive tumor-feeding artery in 72 lesions, which included true-positive tumor-feeding artery in 68 and false-positive one in 4. The sensitivity of CBCT-HA in judging tumor-feeding artery was 90.7% (68/75), which was much higher than that of DSA-HA (42.6%, 32/75), the difference was statistically significant(P<0.001). The positive predictive value of CBCT-HA in detecting tumor-feeding artery was also higher than that of DSA-HA (94.4% vs. 80.0%; P=0.040). Conclusion Cone-beam CT hepatic arteriography is obviously superior to DSA hepatic arteriography in identifying tumor-feeding arteries, which is very helpful in guiding super-selective TACE for HCC.

OBJECTIVE: To realize the automated assessment of the levels of epiphysis of distal radius and ulna by support vector machine (SVM). METHODS: The X-ray films of the left wrist joints were taken from 140 teenagers aged from 11 to 19 years old as training samples. The levels of epiphysis of distal radius and ulna were divided into five developmental levels. Each level contained 28 samples. Another 35 cases were selected as independent verifying samples. SVM classification models of the five developmental levels of epiphysis of distal radius and ulna were established. The internal cross validation was made by leave one out cross validation (LOOCV), while the external validation was made by histogram of oriented gradient (HOG), and then the accuracy (PA) of testing results was calculated, respectively. RESULTS: The PA of SVM, LOOCV and HOG of distal radius epiphyseal level were 100%, 78.6%, and 82.8%, respectively; whereas the PA of SVM, LOOCV and HOG of distal ulna epiphyseal level were 100.0%, 80.0% and 88.6%, respectively. CONCLUSION The SVM-based automatic models of the growth stage of distal ra- dius and ulna appear to have certain feasibility, and may provide a foundation for software development of bone age assessment by forensic medicine.

OBJECTIVETo investigate the time trends and age-related characteristics of mortality and disease burden for cardiocerebrovascular diseases (CVD) in Hunan, China during three periods (1973-1975, 1990-1992 and 2004-2005).

METHODSThe cardiocerebrovascular death data of Hunan residents were collected by three national retrospective sample surveys of death. Cause-specific mortality, proportion, years of potential life lost (YPLL) and associated indicators were identified in the population of Hunan in above mentioned three periods. Time trends of age-specific mortality rate were assessed by fitting curvilinear regression lines and the increase rates of mortality with age were analyzed in each period.

RESULTSThe standard all-cause mortality of residents in Hunan decreased (chi2 = 189.947, P < 0.001, chi2 = 54.201, P < 0.001; chi2 = 27,396.898, P < 0.001) while the standard mortality for CVD increased (chi2 = 54.201, P < 0.001; chi2 = 27,396.898, P < 0.001) from 1973 to 2005. The age-specific mortality rate for CVD increased with age in all three periods, especially for citizens older than 60 years. There were age stages in each period in which the mortality increase rate was the fastest (10-14 and 15-19 years old in 1973-1975; 10-14, 15-19 and over 80 years old in 1990-1992; 15-19 and over 80 years old in 2004-2005). Exponential regression function (y = b0e(b1x)) can be used for the proper description of age-specific mortality change. The ratio of YPLL for CVD in all death causes showed increase trend (chi2 = 275,630.407, P < 0.001). YPLL rate (YPLLs per 1000) in 1973-1975 was higher than those in 1990-1992 and 2004-2005. YPLL rate was positively correlated with mortality in all periods.

CONCLUSIONSThe mortality for CVD increased with time and aging. People older than 60 years were threatened by CVD mostly. Mortality trend analysis also found higher CVD deaths in people age 15-19 in Hunan residents.
