Objective To evaluate the prognostic value of fluorodeoxyglucose (FDG) standardized uptake value (SUV) of positron emission tomography (PET) before radiotherapy in non-small cell lung cancer (NSCLC) treated with three-dimensional conformal radiation therapy (3DCRT). Methods Seventy-three patients with stage Ⅲ NSCLC underwent PET to calculate SUV within 2 weeks before 3DCRT. The a-nalysis was carried out after the irradiation of 60 -66 Gy. The possible prognostic factors were assessed by Cox proportional hazards model. Results The mean SUV for squamous cell carcinoma, adenocarcinoma and others were 16.94, 14.40 and 6.33, respectively (F = 0. 51, P = 0. 604). The mean SUV for tumor volume less than and more than 50 cm~3 was 13.81 and 20.18 (F = 7.54, P = 0. 008). In the univariate analysis, a cutoff SUV of 17 and chemotherapy were correlated with the prognosis. In the multivariate analysis, SUV was the only independent prognostic factor (relative risk = 2.61). Conclusions SUV is a prognostic factor in patients with NSCLC treated by 3DCRT, which deserves further studies.

Objective To compare the efficacy and complications between transurethral resec-tion of the prostate(TURP) and transurethral vaporization-resection of the prostate (TUVRP). Methods 637 cases of benign prostatic hyperplasia(BPH)were divided into 2 groups, 298 cases un-derwent TURP and 339 underwent TUVRP. The maximal flow rates (Qmax) were (9.8±2.3)ml/s, (10.1±2.1) ml/s, the international prostatic symptom scores (IPSS) were 15.3±3.1,15.1±3.7 re-spectively. The surgical outcomes and the complications of the 2 groups were analyzed. Results For the TURP group and TUVRP group, the postoperative Qmax were (19.0±2.9)ml/s and (18.0±2.3) ml/s, both significantly higher than those of preoperation(P<0.01). There was no significant differ-ence between the 2 groups(P0.05). For the TURP group, the mean operation time was (52±16) rain, visual hematuria lasting for (9.0±2.3) d, secondary bleeding in 6 cases (2.0%), lower urinary tract infection in 14 cases(4.7%), 1 month after operation lower urinary tract symptom(LUTS) in 26 case(8.7%), IPSS was 5.0±1.4, contemporary incontinence in 6 cases(2.0%), memberanous sticture 4 cases(1.3%). For the TUVRP group, the mean operation time was (68%19)min, visual hematuria lasting for (12.0±3.6) d, secondary bleeding in 19 cases (5.6%), lower urinary tract infection in 38 cases(11.2%) ,1 month after operation LUTS in 59 cases(17.4%) ,IPSS was 8.0±1.6,contemporary incontinence in 13 cases(3.8%), memberanous stieture in 16 cases (4.7%). There were significant differences between the 2 groups. For the TURP group, blood loss during operation was (126±29) ml, resected tissue weighed (31±8)g, pre- and post-operative serum natium consentration balance was (8±6)mmol/L,TURS developed in 3 cases(1%). For the TUVRP group, blood loss during opera-tion was (122±38)ml, resected tissue weighed (33±9)g,pre- and post-operative serum natium con-sentration balance was (7±7) mmol/L, TURS developed in 2 cases(0.6%). There was no significant differences(P0.05). Conclusions TURP and TUVRP have similar efficacy treating symptomatic BPH. The incidences of complications of TUVRP are slightly higher than those of TURP.

OBJECTIVE: To explore the relationship between the pink teeth phenomenon and the cause of death as well as its significance in forensic medicine. METHODS: Inspection method was adopted to observe the pink teeth phenomenon in different causes of death. Ten rats were selected for every experimental groups, which were then divided into two groups: Eight in fresh group with teeth pulled immediately, and two in decayed group with body decayed in water firstly. The teeth pulled from rats were immersed in 75% alcohol and observed at different immersion time. RESULTS: In every fresh groups, pink teeth phenomenon was not observed when they were pulled immediately, whereas it emerged gradually after the teeth immersed in 75% alcohol, and the color showed distinct and constant four hours later. In decayed groups, Pink teeth phenomenon was observed immediately when teeth pulled, it became distinct and constant after one hour's immersion in alcohol. So it was more distinctive in the decayed groups than that in the fresh groups. CONCLUSION There is no significant connection between the pink teeth phenomenon and the cause of death, thus it may not be subject to forensic identification.

Objective To analyze injury characteristics and treatment of hospitalized patients wounded in Wenehuan earthquake so as to provide references for medical rescue in disasters. Methods The study involved data of seismic patients from Trauma Database System Version 3.0 that collected clini-cal data of seismic patients admitted into West China Hospital of Sichuan University, Chengdu, and First and Second Hospitals of Deyang City. Trauma Database System Version 3.0 was developed by Research Institute for Traffic Medicine of PLA, Research Institute of Surgery, Daping Hospital, Third Military Medical University, Chongqing. A comparative analysis was done on patient distribution, injury severity and medical treatment. Results There were 826 qualified patients including 410 males and 416 females ( at age range of 1-102 years, mean 45.8 years). Of all, the patients at age of 31-60 years accounted for 50. 2%. The patients were mainly peasants (43.8%, 208/477), workers (15.7%, 75/477) and students (14.1%, 67/477). Blunt injury (53.2%), crush/bury injury (22.5%) and slip/fall injury were three main causes for injury. The patients for 92.1% were admitted into two hospitals of the City of Deyang within four days after earthquake, while 81.7% of patients were admitted into West China Hospital in Chengdu at days 3-9 after earthquake. Patients with bone injuries accounted for 75.3%. The patients had abbreviated injury score (AIS) for mainly 1-3 points, with incidence rate of se-vere multiple trauma ( ISS > 16 points) of 8.2%. Internal fixation was done in 120 patients ( 34. 1% ), debridement and suturing in 103 (29.3%), external fixation in 55 ( 15.6% ), extremity amputation in 22 (6.3%) and intracerebral surgery in 2 (0.6%). Conclusions The injuries are mainly induced by collapse of buildings during earthquake. Bone injuries are predominant injury type, with AIS of mainly 1-3 points and few severe multiple trauma. The results show that the patients receive late special treat-ment and slow evacuation, indieating necessity of strengthening capacity of early medical treatment and ef-fective evacuation during destructive natural disasters.

BACKGROUNDVon Hippel-Lindau disease (VHL), a heritable autosomal dominant disease characterized by neoplasia in multiple organ systems, has rarely been reported in Asia. We genetically investigated a unique Chinese family with VHL disease and performed an analysis of the VHL protein stability.

METHODSGenomic deoxyribonucleic acid (DNA) extracted from peripheral blood was amplified by polymerase chain reaction (PCR) to three exons of the VHL gene in 9 members of the Chinese family with VHL disease. PCR products were directly sequenced. We estimated the effects of VHL gene mutation on the stability of pVHL, which is indicated by the free energy difference between the wild-type and the mutant protein (ΔΔG).

RESULTSThe Chinese family was classified as VHL type 1. Three family members, including two patients and a carrier, had a T to G heterozygotic missense mutation at nucleotide 515 of the VHL gene exon 1. This missense mutation resulted in the transition from leucine to arginine in amino acid 101 of the VHL protein. There was low stability of the VHL protein (the ΔΔG was 12.71 kcal/mol) caused by this missense mutation.

CONCLUSIONSWe first reported a family with this VHL gene mutation in Asia. This missense mutation is predicted to significantly reduce the stability of the VHL protein and contribute to the development of the renal cell carcinoma (RCC) phenotype displayed by this family. The genetic characterization and protein stability analysis of families with VHL disease are important for early diagnosis and prevention of the disease being passed on to their offspring.
