OBJECTIVETo study the value and the clinical application of the Medical Image three-dimensional Visualization System of Abdomen (MI-3DVS) in diagnosis and evaluating resectability of pancreatic tumor.

METHODSTwelve patients with pancreatic tumor were tested with 64-slice helical CT (64-MSCT) angiography, and the CT data was reconstructed with MI-3DVS from November 2008 to August 2009. The 3D findings were adopted in diagnosis and evaluating resectability, and the results were compared with surgical operation and the pathological finding. There were 7 male and 5 female, aged from 14 to 83 years. Within the 12 cases, there were 4 cases with pancreatic carcinoma, 5 cases with pancreatic solid pseudopapillary tumor, 2 cases with pancreatic serous cystadenoma, 1 case with pancreatic cyst (ductal epithelial papillary hyperplasia).

RESULTSNine tumors which had been regarded as removable pre-operatively with MI-3DVS were removed successfully. Three patients who were considered unresectable by other hospitals with CT were operated successfully with MI-3DVS. The other 3 patients' tumors were actually not able to be removed as pre-operative evaluation.

CONCLUSIONMI-3DVS plays an important role in diagnosis and assessment of resectability of pancreatic tumor.

Objective To observe the clinical effect of Shumu-Yuntu-Zhike decoction with conventional treatment for the Gastroesophageal Reflux Cough (GERC).Methods A total of 64 patients with GERC were randomly divided into the conventional treatment group and the combined treatment group, 32 in each. The conventional treatment group took the Rabeprazole capsule and Mosapride Citrate Tablets, and the combined treatment group received the traditional prescription of Shumu-Yuntu-Zhike decoction on the basis of the conventional therapy. Two groups were treated for 8 weeks and evaluated the effect with the Visual analogue scale (VAS), Reflux diagnostic questionnaire (RDQ) and Chronic cough impact questionnaire (CCIQ) before and after 4 and 8 weeks' treatment.Results After 4 week treatment, the VAS (4.47 ± 1.32vs. 6.22 ± 1.34;t=-5.859,P<0.01), CCIQ (32.60 ± 5.83vs. 47.32 ± 5.56,t=-11.548,P<0.01) in the combined treatment group decreased significantly than the conventional group, but the RDQ (13.62 ± 2.89vs. 13.67 ± 2.77;t=-0.079, P=0.937) showed no significant difference between the two groups. After 8 weeks' treatment. After 8 week treatment, the VAS (2.57 ± 1.69vs. 4.55 ± 2.06;t=-4.676,P<0.01), CCIQ (12.47 ± 3.41vs. 23.47 ± 3.55;t=-14.126,P<0.01) in the combined treatment group decreased significantly, but the RDQ (9.18 ± 2.77vs. 9.3 ± 2.43,t=-0.202,P=0.841) showed no significant difference between the two groups. After the treatment, the total effective rate of combined treatment group was 90.6% (29/32), while the control group was 68.7% (22/32). There was significant difference between the two groups (χ2=4.730,P=0.030).Conclusions The therapy of Shumu-Yuntu-Zhike decoction combined with conventional therapy can relieve the symptom of gastroesophageal reflux cough.

AlM:To discuss the protective effect ofα-mangostin on retinal light damage in mice.METHODS:Totally 30 Balb/c mice, aged 6~8wk, were randomly divided into the control group, light-exposure group and α-mangostin group. Every group contained 10 mice. Mice of α-mangostin group were treated with alpha-mangostin at the dose of 30mg/( kg · d ) body weight by intragastric administration daily for 7d, and then exposed to white light at the 5th d. The light-exposure group and α-mangostin group were exposed to 5 000 ± 200lx white light-emmiting diodes (LEDs) for continuously 1h to establish the mice model of retinal light damage. Flash -electroretinograme was recorded 72h after light exposure. The changes in retinal morphology of mice were observed by light microscopy. Retinas were extracted to detect the malondialdhyde ( MDA ) content change of the retinal homogenate.RESULTS: Flash-electroretinogram ( F-ERG ) showed that retinal dysfunction was less severe in α-mangostin group than in light-exposure group ( P<0. 05 ). Light microscopy test showed that retina structural damage was less severe in α-mangostin group than in light-exposure group (P<0. 05). The level of MDA in retinal tissue of α-mangostin group was significantly lower when compared with light-exposure group (P<0. 05).CONCLUSlON: α-mangostin inhibits lipid peroxidation induced by light damage and protect retina against light damage.

Objective To evaluate the prognosis of full-term neonates with birth asphyxia usingneonatal behavioral and neurological assessment (NBNA). Methods A total of 326 full-term neonateswith birth asphyxia were evaluated using NBNA 12-14 days and 25-28 days after birth. The infants werefollowed up till 24 months old and a developmental assessment was made according to the CDCC Scalesof Infant Development. Results The incidence of developmental retardation (with mental developmentindex ≤69 or psychomotor development index ≤69) was significantly higher in the infants with NBNAscores ≤35 than in those with NBNA scores >35. Conclusion The NBNA score provides a valuablereference for prognostic evaluation of the full-term neonates with birth asphyxia, and may serve as asensitive indicator for cerebral lesions.

OBJECTIVETo explore the effects of hyperbaric oxygen (HBO) treatment on the neuronal apoptosis at an earlier stage and the expressions of Cytochrome C (Cyt C), Bcl-2 (B-cell lymphoma-2 family) and Bax (Bcl-2 associated X protein) in rat brain tissues after traumatic brain injury (TBI).

METHODSForty adult rats were divided into two groups, i.e., Group A (the rats with untreated TBI) and Group B (rats with HBO treatment after TBI). Sections of brain tissues of these two groups were then detected at 3, 6, 12, 24, 72 hours after TBI by immunohistochemistry and electronmicroscope, respectively.

RESULTSHBO treatment could up-regulate the expression of Bcl-2 within 72 hours, reduce the release of Cyt C from mitochondria, attenuate the formation of dimeric Bax and alleviate the mitochondrial edema within 24 hours after TBI.

CONCLUSIONSHBO treatment can alleviate neuronal apoptosis after TBI by reducing the release of Cyt C and the dimers of Bax and up-regulating the expression of Bcl-2.

OBJECTIVETo explore cytological parameters that may identify the primary sites of metastatic adenocarcinomas in serous fluid.

METHODSSerous fluid specimens from 89 cases of metastatic adenocarcinomas (40 metastatic adenocarcinomas of lung, 6 metastatic adenocarcinomas of breast, 21 metastatic ovary adenocarcinomas, 22 metastatic gastrointestinal and pancreatic adenocarcinomas) were studied by using multiple morphologic parameters. Immunocytochemical S-P method was used to detect the expression of CA125, CA199, SPB and TTF-1 in 75 cases.

RESULTSMetastatic adenocarcinomas of different primary sites displayed certain different morphologic features, including the total amount of tumor cells, size of clusters, ratio of clusters over single cells, configuration of tumor clusters and the background of the smear. Cell clusters of small to medium sizes represented 95% and 100% in the metastatic adenocarcinomas of lung and breast, respectively. Most of the ovarian metastatic adenocarcinomas (85.7%) presented some large cell clusters and larger amount of cells, whereas certain metastatic gastrointestinal and pancreatic adenocarcinomas (45.5%) presented smaller number of cells and predominantly to be single cell in distribution (40.9%). Psammoma bodies were found in metastatic adenocarcinomas of lung and ovary. SPB and TTF-1 expression supported the diagnosis of adenocarcinoma of pulmonary origin. CA125 expression supported an ovarian origin. Although CA199 was seen in all groups of metastatic adenocarcinomas, nevertheless, its appearance in tumor cells in ascitic fluid specimens supported gastrointestinal and pancreatic origins.

CONCLUSIONMorpho-logic features of the cytological smear, immunohistochemical staining and clinical history are equally important in determining the primary sites of metastatic adenocarcinomas in serous fluid.

Objective To investigate the dietary pattern in college freshmen students and to analyze the influencing factors on their dietary patterns. Methods A questionnaire survey on situation of dietary pattern and influencing factors was conducted among 1319 freshmen students.Results Four major dietary patterns were noticed and they were: Ⅰ , high consumption in hamburger,fried food, nuts, biscuit, chocolate, cola, coffee, sugars, Ⅱ, high consumption in pork, mutton, beef,poultry meat, animal liver, Ⅲ, high consumption in fresh fruits, eggs, fish and shrimps, kelp laver and sea fish, milk and dairy products, beans and bean products, Ⅳ, high consumption in rice and grain,fresh fruits, fresh vegetables, pork. Risk factors on dietary pattern were presented as follows: ( 1 )boys: having the food pattern Ⅰ and Ⅱ showed a strong positive association with the place where they live (OR= 1.67, 95％CI: 0.87-3.19; OR= 1.51,95％CI: 0.79-2.88), eating place (OR=1.63,95％CI: 1.O3-2.59; OR= 1.83, 95％CI: 1.04-3.23), level of mother' s education (OR=2.52,95％CI: 1.07-5.95; OR=3.38, 95％CI: 1.50-7.63), family income (OR=2.24, 95％CI: 1.30-3.88;OR=3.06, 95％ CI: 1.77-5.29) and the status of passive smoking (OR= 1.80, 95％CI: 0.70-4.59;OR=1.83, 95％CI: 0.75-4.45). Inverse correlations was found on the level of mother's education (OR=0.56,95％CI: 0.17-1.79). The food pattern Ⅳ showed a strong positive association with place of eating(OR= 1.83,95％CI: 1.04-3.23) but having an inverse correlation with the level of mother's education (OR=0.56, 95％CI: 0.17-1.79). (2)girls when compared with boys, the food pattern Ⅰ showed minor association with the places of living and eating; while the food pattern Ⅱ and Ⅲ had minor association with the status of passive smoking. Conclusion Socio-demographic factors and lifestyle had influenced on the dietary patterns among college freshmen students who should be guided to have a reasonable, balanced diet in the college.

Human-animal parasitic diseases caused by medical helminths are hazardous to human health. Genetic polymorphism studies on medical helminth populations can not only understand the biological characteristics and genetic structure of their populations, but also help reveal how they adapt to their parasitic environment, thus contributing to deepen our understanding of the epidemiological patterns of parasitic diseases and improve our understanding of accurate prevention and control of parasitic diseases. With the development of molecular biology, molecular markers such as DNA barcodes, simple sequence repeats, and single nucleotide polymorphism markers have been widely used to study the genetic relationships among parasite populations and individuals, and to reveal the genetic variation of parasite populations and the evolution of species origins. In this paper, we systematically review the application of three molecular markers commonly used in the study of genetic polymorphism in medical helminths, with a view to laying the foundation for related research.

OBJECTIVETo study the clinicopathologic features of different variants of primary focal segmental glomerulosclerosis (FSGS).

METHODSOne hundred and two cases of FSGS were retrieved from the archival files of Peking University First Hospital during the past 6-year period. The pathologic findings were reviewed and the degrees of active and chronic changes were assessed by morphometric analysis. The histopathologic patterns were then correlated with clinical manifestations.

RESULTSAmongst the 102 cases of primary FSGS studied, 55.9% belonged to the NOS (not other specified) variant, while the perihilar, cellular, tip and collapsing variants accounted for 6.9%, 25.5%, 4.8% and 6.9% respectively. The level of proteinuria in the cellular and tip variants were much higher than that in the NOS variant; and the incidence of nephrotic syndrome in the tip and collapsing variants was higher than that in the other three variants (chi(2) = 12.23, P < 0.05). The activity score of the cellular and collapsing variants was also higher than that of the other three variants (P < 0.05). The interval between disease onset and renal biopsy diagnosis in the perihilar variant was longer than that in the other variants. The chronicity score of this variant was higher than that of the tip and NOS variants (P < 0.05). On the other hand, the total scores of active and chronic changes of the tip variant was lower than that of the cellular and collapsing variants (P < 0.05); and its chronic score was lower than that of the NOS and perihilar variants (P < 0.05).

CONCLUSIONSThe NOS variant is the commonest morphologic pattern seen in primary FSGS. The cellular and collapsing variants are the patterns associated with active lesions, while perihilar variant is the pattern associated with chronic lesions. The tip variant shows mild pathological changes compared with the other patterns.
