Objective To compare the efficacy after conventional radiotherapy and late course accelerated fractionation radiotherapy for nasopharyngeal carcinoma (NPC).Methods A total of 200 NPC patients were enrolled and randomly assigned to conventional radiotherapy (CF) group with 99 cases or late course accelerated fractionation radiotherapy (LCAF) group with 101 cases,who received irradiation to 60Co γ or 6 MV X-rays.In the CF group,the total dose of nasopharynx was 70 Gy/35 fractions at 2 Gy daily.In the LCAF group,for the first two-thirds of the treatment,two daily fractions of 1.2 Gy were given to the primary lesion and the total dose was 48 Gy/40 fractions.For the last one third of the treatment,the dose per fraction was increased to 1.5 Gy and the total dose was 30 Gy/20 fractions.Results There were 25,16,25 in CF group and 16,13,18 patients in LCAF group who had recurrence of nasophaynx,cervical lymph nodes,and distant metastasis,respectively.The 5-year nasopharyngeal control and overall survival rates was 75.9％ and 87.6％ in CFgroup (x2 =4.066,P＜0.05),58.0％ and 74.1％(x2 =5.076,P ＜ 0.05) in LCAF group,respectively.Cervical lymph nodes local rates and distant metastasesfree rates at 5 years were 8 1.5％ and 90.0％ in CF group (P ＞ 0.05),74.1％ and 83.3％ (P ＞ 0.05) in LCAF group,respectively.Conclusions Compared with CF,LCAF can improve nasopharyngeal control and overall survival rates,but there are no significant difference in the recurrence rates of cervical lymph nodes and distant metastasis.

AIM: To study the protective effects of basic fibroblast growth factor (bFGF) on myocardial ischemia in rats and their underlying mechanism. METHODS: A rat myocardial ischemic injury model was established by left coronary artery ligation. The rats were killed at 2 h, 4 h, 8 h after coronary artery occlusion. The samples of blood and myocardium were collected for observing the expression of Bcl-2 and Bax in myocardial cells and the changes of superoxide dismutase (SOD) or myocardial enzymes. RESULTS: The amount of Bcl-2 protein expression of myocardial cells in ischemia + bFGF group was significantly higher than that in ischemia+saline group (P

Avian leukosis virus subgroup J (ALV-J) is an avian retrovirus that can induce myelocytomas. A high-frequency mutation in gene envelope endows ALV-J with the potential for cross-species transmission. We wished to ascertain if the ALV-J can spread across species under selection pressure in susceptible and resistant hosts. First, we inoculated (in turn) two susceptible host birds (specific pathogen-free (SPF) chickens and turkeys). Then, we inoculated three resistant hosts (pheasants, quails and ducks) to detect the viral shedding, pathologic changes, and genetic evolution of different isolates. We found that pheasants and quails were infected under the selective pressure that accumulates stepwise in different hosts, and that ducks were not infected. Infection rates for SPF chickens and turkeys were 100% (16/16), whereas those for pheasants and quails were 37.5% (6/16) and 11.1% (3/27). Infected hosts showed immune tolerance, and inflammation and tissue damage could be seen in the liver, spleen, kidneys and cardiovascular system. Non-synonymous mutation and synonymous ratio (NS/S) analyses revealed the NS/S in hypervariable region (hr) 2 of pheasants and quails was 2.5. That finding suggested that mutation of isolates in pheasants and quails was induced by selective pressure from the resistant host, and that the hr2 region is a critical domain in cross-species transmission of ALV-J. Sequencing showed that ALV-J isolates from turkeys, pheasants and quails had moved away from the original virus, and were closer to the ALV-J prototype strain HPRS-103. However, the HPRS-103 strain cannot infect pheasants and quails, so further studies are needed.

Objective To develop an ideal hypertension combined hyperlipidemia(HP/HL)rat model by feeding spontaneously hypertensive rats(SHRs)with high fat diet, and to evaluate the pathological changes in target organs including heart and kidney. Methods Twenty 3-week old male SHRs were randomly divided into two groups: normal fat control group(SHR-NC)and high fat group(SHR-HF). Moreover,ten 3-week old male Wistar-Kyoto rats(WKY)were taken as the model control group(WKY-NC). The rats in SHR-HF group were fed with high-fat diet to induce HP/HL, while rats of WKY-NC and SHR-NC groups were fed with normal diet. The systolic blood pressure(SBP)and body weight were measured every week. At the end of the experiment, the rats were sacrificed to take serum samples for blood lipid analysis including high density lipoprotein(HDL-C), low density lipoprotein(LDL-C), total cholesterol(TC)and triglyceride(TG). Heart and kidney tissue samples were collected to examine the pathological changes using HE and Masson staining. Results Compared with the SHR-NC group, the SHRs fed with high-fat diet for 23 weeks presented significant increase of blood pressure and TC, TG, LDL-C, and decrease of HDL-C. The HP/HL rat model showed pathological changes in the HP/HL target organs, heart and kidney. Renal tissues were severely damaged and showed a large area of fibrosis. Besides, left ventricular hypertrophy and myocardial fibrosis were also observed. Conclusions A HP/HL rat model is successfully constructed by feeding SHRs with high-fat diet for 23 weeks. Most importantly,this model exhibits progressive renal and cardiac alterations, similar to those of patients with HP/HL. This HP/HL rat model may become widely used for evaluation of HP/HL therapeutic drugs.
