Background and purpose: The aim of this study was to determine the necessity of central compartment neck dissection in laryngeal cancer.Study Design: Retrospective study at a tertiary referral medical center. Methods:Patients with laryngeal squamous cell cancer who underwent neck dissection were evaluated, and a retrospective analysis of clinicopathologic factors and follow-up data were performed. Results: One hundred and eighteen patients from 1999 to 2009 were enrolled. There were 11.9% central compartment lymph node metastasis in all patients, including the 10 patients with central compartment lymph node metastasis in 34 patients underwent compartment neck dissection and 4 patients do not underwent compartment neck dissection but had central neck recurrence in the follow up time. Subglottic or pyriform extension were risk factors in central compartment lymph node metastasis and central neck recurrence (P=0.002). Central compartment lymph node metastasis had closed relationship with levelⅣmetastasis (P<0.001), extracapsular extension (P=0.001), vascular extension (P=0.015) and poor local control rates (P=0.035) respectively. Patients who were positive for lateral neck lymph node metastasis had poor disease-free survival rate (P=0.014) and poor local control rates (P=0.025), and supraglottic cancer had a trend to metastases to levelⅡ(P=0.044). Conclusion:Central compartment neck dissection might be considered a potential therapeutic approach for patients with laryngeal cancer.

OBJECTIVETo study therapeutic effects between hook plate fixation and modified Weaver-Dunn surgery for the treatment of acromioclavicular joint dislocation.

METHODSForty patients with fresh acromioclavicular joint dislocations of type III according to Rockwood classification were reviewed. All the patients were divided into two groups: hook plate fixation group and modified surgery group. There were 20 patients in hook plate fixation group, including 13 males and 7 females, with an average age of (37.45 +/- 14.29) years old; 12 patients had injuries in the left and 8 patients had injuries in the right; preoperative Constant-Murley score was 40.75 +/- 10.40. And there were 20 patients in modified surgery group,including 11 males and 9 females, with an average age of (41.65 +/- 14.83) years old; 11 patients had injuries in the left and 9 patients had injuries in the right; preoperative Constant-Murley score was 42.75 +/- 8.18. The Lazzcano standard, Constant-Murley score and imaging changes were used to evaluate shoulder joint function before and after surgery.

RESULTSAll the patients were followed up,and the duration ranged from 7 to 32 months,with an average of 24 months. According to Lazzcano evaluation, 16 patients got an excellent result,3 good and 1 poor in modified surgery group with no re-dislocation, and 1 patient had pain more than middle degree; while in hook plate fixation group, 9 patients got an excellent result, 7 good and 4 poor, 1 patient had re-dislocation, and 3 patients got pain more than middle degree. The therapeutic effects of modified surgery group were better than those of hook plate fixation group. Constant-Murley scores:preoperative 42.75 +/- 8.18 vs 93.40 +/- 4.04 at the latest follow-up in modified surgery group; preoperative 40.75 +/- 10.40 vs postoperative 88.40 +/- 4.81 and 92.05 +/- 4.49 at the latest follow-up in hook plate fixation group. The postoperative scores all improved compared to preoperative scores in two groups. And there was no statistical difference of scores at the latest follow-up between two groups.

CONCLUSIONThe surgery of allograft tendon transplantation combined with anchor fixation to strengthen coracoclavicular ligament, as well as part transposition of acromiocoracoid ligament and resection at the distal part of clavicle may got safety fixation and less postoperative complications compared with hook plate internal fixation.

OBJECTIVETo investigate the expression of thymidylate synthase (TS) in patients with advanced lung adenocarcinoma and its relation with the therapeutic effect of pemetrexed.

METHODSThe clinicopathological data of 38 patients with stage IIIIB/IV lung adenocarcinoma receiving pemetrexed treatment were retrospectively analyzed. The tumor samples of the patients were collected for detecting TS expression using RT-PCR, and the therapeutic effect of the treatment was analyzed.

RESULTSTS positivity was found in 26.32 (10/38) of the patients. TS positivity was not correlated to gender, TNM stage or PS score. The total response rate of pemetrexed treatment (CR+PR) was 34.21 (13/38) in these patients, and the rate was 39.29% (11/28) in TS-negative patients, as compared to 20.00% (2/10) in the positive patients (P=0.087). Patients with low TS expression had significantly higher control rate by pemetrexed treatment than those with TS overexpression [89.29% (25/28) vs 40.00% (4/10), P=0.002].

CONCLUSIONTS expression may serve as a potential indicator of chemosensitivity to pemetrexed in patients with advanced lung adenocarcinoma.

OBJECTIVETo study the role of procalcitonin (PCT) in the diagnosis of acute pyelonephritis (APN) in children.

METHODSRetrospective analysis was performed on the clinical records of children aged under 3 years who were diagnosed with primary urinary tract infection (UTI) from September 2011 to February 2012. These children were divided into those with upper UTI (UUTI) (APN) and those with lower UTI (LUTI) (non-APN) based on 99mTc-dimercaptosuccinic acid (DMSA) renal scan results as a gold standard. The UUTI and LUTI groups were compared in terms of serum levels of PCT and C-reactive protein (CRP). Receiver operating characteristic (ROC) curves were drawn to evaluate the diagnostic values of serum PCT and CRP.

RESULTSSixty-five children with UTI, including 39 cases of APN and 26 cases of LUTI, were included in this study. The APN cases had significantly higher serum levels of PCT (3.08 ng/mL vs 0.37 ng/Ml; P<0.01) and CRP (6.25 mg/L vs 3.01 mg/L; P<0.01) than the LUTI cases. The sensitivity and specificity of serum PCT level for APN were 84.6% and 88.5%, respectively, with an area under the ROC curve (AUC) of 0.873 (95%CI=0.781-0.965) and an optimal threshold point of 1.03 ng/mL. The sensitivity and specificity of serum CRP level for APN were 71.8% and 69.2%, respectively, with an AUC of 0.735 (95%CI=0.612-0.858) and an optimal threshold point of 3.91 mg/L.

CONCLUSIONSAs a result of its high sensitivity and specificity for the disease, serum PCT can be used as a marker in the early diagnosis of APN in children.

BACKGROUNDThere were some papers published in the Jonrnal of Science, December 2000 suggesting that one or more important susceptibility genes for late onset Alzheimer's disease (LOAD) were located on the long arm of chromosome 10. Linkage analysis showed maximum lod score close to D10S1225 loci, which indicated the loci might contribute to the etiology of Alzheimer's disease (AD).

METHODSFifty-nine LOAD patients and 107 controls were recruited. Apolipoprotein E (ApoE) genotypes were determined by reverse dot blotting hybridization assay. The D10S1225 was genotyped by 12% nondenaturing polyacrylamide gels electrophoresis and analyzed by silver staining. Statistical analysis was used to compare genotype and allele distributions between LOAD group and control group for ApoE and D10S1225 polymorphisms.

RESULTSApoE epsilon 4 was significantly higher in LOAD group in comparison with the control group (chi(2) = 6.530, P = 0.011). Seven different alleles of D10S1225 have been identified. The length of these gene fragments were 178 bp, 181 bp, 184 bp, 187 bp, 190 bp, 193 bp, and 196 bp, respectively. A total of 21 different genotypes were observed. There was no relationship between D10S1225 polymorphism and LOAD (chi(2) = 4.488, P > 0.05). Conclusion This study suggests that ApoE epsilon 4 is a risk factor for LOAD, however, the results indicated that there is not any possible linkage for disequilibria with a nearby AD risk gene near D10S1225.

OBJECTIVETo investigate the effects of adefovir dipivoxil (ADV) on blood phosphorus metabolism in patients with chronic hepatitis B (CHB).

METHODSPatients with hepatitis B surface antigen (HBsAg)-positive CHB were treated with ADV alone, ADV combined with interferon (IFN), or ADV combined with lamivudine (LAM). Changes in levels of calcium, phosphate, urea, and creatinine were assessed at treatment weeks 4, 12, 24, 48, 72 and 96. Statistical analysis was carried out with SPSS 16 software; influential factors were analyzed by ANOVA and non-conditional logistic regression analysis.

RESULTSDuring the course of treatments, 32 (42.6%) of the patients presented with low phosphorus. The highest incidence of low phosphorus was found to have occurred at treatment week 24 (25.0%, 27.5% and 36.4% respectively, with no statistical difference between three groups, x2=0.225, P>0.225). Patients with hypophosphatemia did not show a significant difference in serum phosphorus levels from the other patients (F=1.853, P=0.169). Logistic regression showed a correlation between low phosphorus and sex (x2=7.876, P<0.05), age (t=2.479, P<0.05), and serum creatinine (t =-2.256, P<0.05), but not with blood urea nitrogen or blood calcium (P>0.05).

CONCLUSIONADV antiviral treatment can decrease the blood phosphorous levels of CHB patients, particularly over extended time of treatment, and the occurrence of low phosphorus is more common than of mild phosphorus decrease.Male and elderly patients may be at greater risk of this complication. The incidence and severity of low phosphorus is not significantly different for the different ADV-based treatment regimens.

OBJECTIVETo explore the clinical features and gene mutation profiles of patients with chronic hepatitis B (CHB) and Gilbert's syndrome.

METHODSThirty-three patients with CHB and Gilbert's syndrome were enrolled in the study. Serum markers of liver function and histological features of disease-related liver injury were assessed by standard methods. Gene mutations were detected by PCR and direct DNA sequencing.Statistical analysis was carried out with the chi-square and t tests.

RESULTSSequencing of the Gilbert syndrome-associated gene, UGT 1A 1, revealed mutations in the upstream promoter phenobarbital-responsive element module (PBREM) (-3279 mutation, 23 cases), in the promoter TATA box (a TA insertion mutation, 21 cases), and in the coding region of exon 1 (a GGA-AGA Gly71Arg mutation, 18 cases); there was no statistical difference found for any of the three mutations among this patient population (x2 =1.640, P more than 0.05).

CONCLUSIONThe traditional methods of diagnosis for patients with CHB and Gilbert's syndrome remain a technical challenge in the clinic, and gene detection may represent a more favorable method for diagnosing this patient population.
