Objective To study the clinical and pathological features of rectal carcinoid and factors influencing the prognosis.Methods Data of 33 rectal carcinoid patients were analyzed retrospectively. 29 patients were followed up postoperatively. Primary tumors were classified by size (2*!cm) and muscularis invasion respectively.Results The main symptoms were changes in bowel habits(17/33,52%) and hematochezia (14/33, 42%), or rectal mass (14/33,42%), asymptomatic patients were detected during a survey.Only 4(12%) patients had tumors larger than 2 cm and tumors invading muscularis.The 10 year survival rate was 84% for all patients( n =29), and 94% for those with tumors 2*!cm( n =3) died in 5 years( P = 1 0?10 -9 ) and only one out of the 4 with muscularis invasion lived longer than 5 years( P =1 2?10 -5 ).Conclusions Most rectum carcinoid are at early stage suitable for local excision.

AIM The purpose is to study the non-isothermal decomposition process and mechanics of vitamin B6. METHOD The TG technique was used to observe between 30~700℃. RESULTS The decomposition of vitamin B6 was performed by two stages. Vitamin B6 loses HCl at the first stage together with losing H2O. The kinetic equation obtained was dα/dt=A*e-E/RT*1/2(1-α)3; activation energy obtained was 325.27 kJ/mol; and preexponential factor A obtained was 7.22×1032/s as well. CONCLUSION Vitamin B6 is rather thermal stable, and it loses HCl together with losing H2O at temperature range of 173℃~271℃.

Objective To evaluate the effect of consecutive diet nursing intervention on elderly patients with type 2 diabetes. Methods 56 elderly type 2 diebetes patients were randomly selected in control group and were given conventional type 2 diabetes management. The other 56 patients in experimental group were not only given routine care, but also 3 months of consecutive diet nursing intervention. At the 1st and 3rd month, assessment of blood glucose test and quality of life were conducted by all patients conducted. T test, chi-square test were used in the statistics. Results In experimental group, the controlling effect of fasting plasma glucose and 2-hour postprandial blood glucose have been significantly improved. 3 months after the consecutive diet nursing intervention, fasting plasma glucose of control and experimental groups were (7.18±0.89) mmol/L and (6.37±0.74) mmol/L (P=0.027). After 1 months of the consecutive diet nursing intervention, 2-hour postprandial blood glucose of control group and the experimental group were (11.69 ± 1.58) mmol/ L and (9.03 ± 2.13) mmol/ L (P = 0.028) respectively. After 3 months of intervention, the number were were (12.12±2.36) mmol/L and (8.36±1.65) mmol/L respectively (P<0.01). In the experimental group, the therapeutic dimension of quality of life has been gradually decreased and the difference was statistically significant. Conclusions Consecutive diet nursing intervention can effectively improve the blood glucose control of elderly type 2 diabetes patients.

Objective To explore the related risk facts of pulm onary throm boem bolism (PTE ) and analyze the relation betw een PTE and the traum a or m edical behavior by investigating the cases of PTE . Methods Thirty-three cases w ere selected from Institute of Forensic Science (IFS) from 2000 to 2014. Results In 33 cases, 16 decedents w ere m ale, 17 decedents w ere fem ale;different degrees of dyspnea, chest tight-ness and syncope sym ptom s w ere the clinical m anifestation of the deceased; the throm bus w as mainly distributed in the left and right pulm onary arteries. The main source of em bolism w as the deep vein of low er lim b and the left probability w as higher. Traum a, lim ited position, operation and cardiovascular disease show ed high-risk factors of PTE; D-D im er test, hem olytic test and com puter tom ography pul-m onary angiography w ere the diagnostic tools for PTE . In som e cases, traum a and m edical m alpractice could be involved in the cause of death. Conclusion N on-typical clinical sym ptom s present in the m ost cases caused by PTE , and these cases alw ays show m any high-risk factors. The relation betw een PTE and injury or m edical behavior should be considered carefully in the forensic pathological practice.

Objective To explore the application value of postm ortem m ulti-slice spiral com puted tom o-graphy (MSCT) by observing and analyzing the injury features in the traffic accident victim s. Methods Ten traffic accident victim s w ere scanned w ith w hole body MSCT. The system ic autopsy w as subse-quently perform ed to com pare w ith the results of MSCT. The advantages and disadvantages of autopsy and MSCTfor obtaining the inform ation of traffic accident injuries w ere then analyzed. Results MSCTcould reveal 3D shape of fractures clearly and detect air accum ulation in different positions of the body, w hich show ed the obvious advantages com pared w ith autopsy. H ow ever, the resolution of MSCTw as lim ited com pared to the detection of organ and soft tissue injuries. Conclusion A com bination of MSCTand autopsy is the best w ay for determ ining the m anner and the cause of death in traffic fatality victim s.

Objective To observe the time-course expression of zonula occludens-1 (ZO-1) in cerebral cortex after traumatic brain injury (TBI). Methods The TBI model of mouse was established. The mice were divided in 1 h, 3 h, 6 h, 12 h, 24 h, 3 d, 7 d after TBI, shamand control groups. The permeability of the blood brain barrier was evaluated by measuring the extravasation of Evans blue (EB) dye. The expression of Z O-1 in cerebral cortex in the injured area was detected by western blotting and im-munohistochemistry. Results The extravasation of EBdye of injured cortex gradually increased from 1 h, peaked at 1-3 d and approximately decreased to normal at 7 d after TBI. western blotting revealed that the expression of Z O-1 gradually decreased after 1 h, was at the lowest at 1-3 d, and then significantly increased after 7 d but was still lower than that of normal and shamgroups. The result of immunohisto-chemistry showed that Z O-1 had strong expression in vessel of normal cortex, gradually decreased after TBI, and almost disappeared at 3 d after TBI and gradually recovered to normal level later. Conclusion The expression of Z O-1 in the injured cortex after TBI initially decreases and then increases. The nega-tive correlation between Z O-1 expression and EBextravasation after TBI could be used as a newindi-cator for wound age estimation.

Objective T o explore the application value of postm ortem com puted tom ography (C T ) an-giography on diagnosis of coronary atherosclerotic stenosis degree. Methods B ased on the previous ex-perim ental results, the postm ortem C T angiography device of hum an isolated heart w as im proved. D iffer-ent coronary atherosclerotic stenosis degree of sudden death cases w as selected. B efore the cardiac anatom y, hearts w ere rem oved out com pletely and C T angiography w as perform ed im m ediately. T he C T angiography results w ere com pared w ith histopathological findings. M eanw hile, the advantages and disad-vantages of the angiography device before and after im provem ent w ere com pared. Results T he im proved angiography device of isolated heart could get better im aging results. T he postm ortem C T angiography results had high consistency w ith the histopathological findings on diagnosis of coronary atherosclerotic stenosis degree. A nd the coronary artery lesions could be revealed m ore objectively and vividly by 3D reconstruction technology. H ow ever, C T angiography could only be used to exam ine the pathological changes of blood vessels, w hich m ight have som e lim itations on the diagnosis of cause of death. Con-clusion Postm ortem C T angiography can be used as an additional m ethod for the conventional autopsy in the cases of coronary atherosclerosis.
