OBJECTIVETo evaluate the efficacy of surgery for the patients with pyriform sinus carcinoma and analyze the prognostic factors related to the cancer.
METHODSBetween December 1995 and December 2002, 62 patients with pyriform sinus cancer were treated in Zhejiang Tumor Hospital. There were 13 patients staged T1, 17 T2, 12 T3, 20 T4. Four patients received preoperative radiation and 40 patients had post-operative radiation. Among 62 patients, 33 patients were treated by partial laryngectomy, 29 patients were treated by total laryngectomy.
RESULTSThe survival rate was calculated with Kaplan-Meier method. The overall 3- and 5-year survival rates were 42.3% and 27.8%, respectively. The 3-year survival rate between partial and total laryngectomy was 51.9% and 29.9%. The 5-year survival rate between partial and total laryngectomy was 39.5% and 11.2% (chi2 = 4.14, P<0.05). Early stage and combined modality therapy were the independent favorable prognostic factors.
CONCLUSIONSEarly diagnosis with treatment and combined treatment are the most important factors influencing the survival of patients with pyriform sinus carcinoma. Partial laryngopharyngectomy is a suitable treatment for early and selected advanced pyriform sinus carcinoma with a good function and oncologic outcome.

OBJECTIVETo assess the reliability and validity of Chinese version of the Abbreviated Burn Specific Health Scale (BSHS-A).
METHODSBSHS-A was translated into Chinese and revised. Eighty-two former burn patients discharged from the Second Affiliated Hospital of Kunming Medical College, and now in rehabilitation stage, were surveyed with the Chinese version of BSHS-A according to the simple random sampling. The psychometric properties of the scale, including internal consistency, test-retest reliability, content validity and discriminant validity, were analyzed.
RESULTSOne hundred and sixty-seven scales were sent to 82 participants and all of them were completed and returned. The rate of eligible questionnaire was 98.2% after eliminating 3 ineligible questionnaires. The Crobach's alpha coefficient of total score of questionnaire was 0.97, and in all domains and sub-domains ranged from 0.83 to 0.96. The test-retest coefficients from 20 participants retested within one week were between 0.74 and 0.98 (P < 0.05 or P < 0.01). Forty-eight participants surveyed within 6 months after burn were divided into mild/moderate burn group and severe burn group. The total scores of questionnaire, scores in all domains and sub-domains of patients in the latter group were lower than those in the former group (P < 0.05 or P < 0.01).
CONCLUSIONSThe Chinese version of BSHS-A shows satisfactory reliability and validity, and it can be used to investigate quality of life of Chinese burn patients in rehabilitation stage.

OBJECTIVE:
To study the clinical features of neuroblastoma (NB) and the factors influencing survival rate.
METHODS:
A total of 44 children with NB who were admitted from April 2016 to February 2020 were enrolled as research subjects. A retrospective analysis was performed on their medical data and follow-up data.
RESULTS:
The common clinical symptoms of these 44 children were fever (10/44, 23%), mass (9/44, 20%), abdominal pain (8/44, 18%), cough (7/44, 16%), pale complexion (3/44, 7%), claudication (2/44, 5%), and abnormal activity (2/44, 5%). According to the INSS stage, 2 children (4%) had stage I NB, 5 children (11%) had stage II NB, 5 children (11%) had stage III NB, and 32 children (73%) had stage IV NB. The mean follow-up time was (15.3±1.5) months, with a recurrence rate of 20% and an overall survival rate of 82%. Among the 44 children, 29 (66%) achieved event-free survival and 7 (16%) had survival with tumor. The univariate analysis showed that a pathological type of NB and an increase in serum neuron-specific enolase (NSE) decreased the overall survival rate of children with NB (P<0.05).
CONCLUSIONS
The clinical symptoms of children with NB are not specific at the first visit. Fever, abdominal pain, and mass are common symptoms, and there is a high proportion of children in the advanced stage. The pathological type of NB and an increase in serum NSE may be associated with a reduction in the overall survival rate of children with NB.

OBJECTIVEChildhood absence epilepsy (CAE), a common form of idiopathic generalized epilepsy, accounts for 8% - 15% of all childhood epilepsies. A positive family history of epilepsy, a hereditary factor being one of the pathogeneses, is found in 15% - 44% of children with absence seizures. The phenotype of CAE is specific (including seizure forms and EEG), therefore it is suitable for genetic study. The purpose of this study was to confirm the linkage of childhood absence epilepsy to chromosome 8q24 in China.
METHODSTwenty-nine trios families (a patient and his/her parents) as patient group and 10 normal trios families as control group were investigated for chromosome 8q24 by haplotype analysis with 5 microsatellite DNA markers (D8S554, D8S534, D8S1100, D8S1783, D8S1753). Genomic DNA was isolated from 4 ml human peripheral blood by using the conventional procedure, and then was treated using the PCR method. PCR products were analyzed by gene scan. Statistical methodology included haplotype-based haplotype relative risk (HHRR) and transmission disequilibrium test (TDT).
RESULTSIn this study, the polymorphism information content (PIC) of 5 microsatellite DNA markers were: 0.519, 0.828, 0.528, 0.654 and 0.772. HHRR showed D8S554(4) (chi(2) = 5.939, P < 0.05), D8S1100(3) (chi(2) = 5.081, P < 0.05), D8S1783(6) (chi(2) = 4.308, P < 0.05). TDT showed D8S554(4) (chi(2) = 4.46, P < 0.05), D8S1783(6) (chi(2) = 4, P < 0.05). In order to exclude false association results, the authors analyzed every family in detail. Four trios families transmitted allele D8S1783(6) to their offspring, and the same allele hasn't been found in controls. The further work showed that locus D8S1783 had transmission disequilibrium with CAE, the other two loci were a false association.
CONCLUSION(1) Childhood absence epilepsy in the Chinese population may be linked to chromosome 8q24, the CAE gene is transmitted disequilibrium on locus D8S1783. Combined with other research results, we suppose that CAE gene may be in the ECA1 area on chromosome 8q24. (2) The CAE gene perhaps has a genetic heterogeneity in the population of different areas and different races. (3) HHRR and TDT seem to be the best statistical methods to do linkage disequilibrium study in the trios family.

OBJECTIVETo explore the effects of p,p'-DDE and beta-BHC on the apoptosis of Sertoli cells in vitro via activation of Caspase.
METHODSSertoli cells were treated in vitro for 24 hours with a serial concentrations of p,p'-DDE (10, 30 and 50 micromol/L), beta-BHC (10, 30 and 50 micromol/L) and p,p'-DDE + beta-BHC (10, 30 and 50 micromol/L). The inhibitory group was first treated with 100 micromol/L Caspase-3 inhibitor Ac-DEVD-CHO treating for 2 hours before 50 micromol/L p, p'-DDE + 50 micromol/L beta-BHC 24 hours-treatment. The vitality of Sertoli cells was determined by MTT and the apoptosis rate was measured by AO/EB double fluorescence staining. The expressions of Caspase-3, Caspase-8 and Caspase-9 were determined by RT-PCR.
RESULTSAverage optical density (A) values were 0.498 +/- 0.039, 0.481 +/- 0.065, 0.397 +/- 0.032 and 0.286 +/- 0.049 in p,p'-DDE groups (10, 30, 50 and 70 micromol/L), and 0.518 +/- 0.103, 0.490 +/- 0.060, 0.454 +/- 0.054 and 0.302 +/- 0.030 in beta-BHC groups (10, 30, 50 and 70 micromol/L). In the mixture-treated groups (10, 30 and 50 micromol/L), the average A values were 0.483 +/- 0.048, 0.473 +/- 0.058 and 0.337 +/- 0.052. Compared with the solvent control group (0.527 +/- 0.022) , 50 micromol/L group of p, p'-DDE, beta-BHC or their mixture caused a significant decrease of Sertoli cell viability (t values were 4.599, 2.716, 6.537 respectively, P < 0.05). AO/EB double fluorescence staining analysis showed that apoptosis rates of Sertoli cells were significantly increased with all treated groups. The expressions of Caspase-3, Caspase-8 and Caspase-9 were upregulated as the concentrations of p,p'-DDE, beta-BHC and their mixture were increased.
CONCLUSIONp,p'-DDE, beta-BHC and their mixture could induce the apoptosis of Sertoli cells in vitro which was associated with activation of Caspase-3 mediated by cleavage of Caspase-8 and Caspase-9.

Objective To investigate the protective effect of ischemic preconditioning (IPC) and penehyclidine hydrochloride (PHC) on the spinal cord against ischemia-reperfusion injury induced by aortic cross-clamping in rabbits. Methods Twenty-four rabbits were randomly divided into sham operation group (A), ischemia-reperfusion injury group (B) and IPC+PHC group (C). In group C, IPC was performed for 5 min, followed by reperfusion for 30 min, and PHC (0.2 mg/kg) was given at 20 min of rcperfusion. Then, in group B and C, the infrarenal aorta was clamped for 40 min followed by 7 d reperfusion. The aorta was not clamped in group A. The plasma concentrations of malondialdehede (MDA), superoxide dismutase (SOD), creatine kinase (CK) and creatine kinase BB isoenzyme (CK-BB) were assayed at 10 min before clamping, before unclamping, at 60 min and on the 7 th day after unclamping. After an operation, the neurological outcomes of the hind limbs were evaluated, the morphology of the spinal cord was observed, and the apoptotic spinal cord cells were measured by immunohistochemical technique. Results The concentrations of MDA, CK and CK-BB after ischemia-reperfusion in group B were increased significantly compared with those before clamping and those in group A (P<0.05 or 0.01); the concentrations in group C were higher than those before clamping (P<0.05), but lower significantly than those in group B (P<0.01), and not significantly different from those in group A. SOD was opposite. The apoptotic cells in group B were much more than that in groupA and in group C, but the number in group C was significantly higher than that in group A (P<0.01). The incidence rate of paralysis in group C was significantly lower than that in group B, and the neurological score of hinder limb was higher in group C than in group B (P<0.01). Pathological changes of the spinal cord was milder in group C than in group B. Conclusion The combination of IPC and PHC can protect the spinal cord from ischemia-reperfusion injury in rabbits; the main mechanism may be increasing antioxidant potential and preventing cell injury.
