OBJECTIVETo determine whether the single nucleotide polymorphism (SNP) on chromosome 12q24.31(rs2259816) is associated with coronary artery disease (CAD) in Han population of southwest China.
METHODSA case-control association study with 592 unrelated patients with coronary artery disease and 463 normal controls from Chinese Han population was performed. Genotype for the SNP on chromosome 12q24.31 (rs2259816) was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).
RESULTSThe genotypes of AA, AC, CC were both detected in the coronary artery disease group and the control group. The frequencies of A allele were 49.5% in case group and 43.8% in control group, showing statistically significant difference(OR=1.129, 95%CI:1.029-1.239, P=0.010).
CONCLUSIONThe replication study showed that the genetic polymorphism in rs2259816 is associated with coronary artery disease in Han population of southwest China.

OBJECTIVETo investigate the frequency of micrometastasis in levels lII - IV of clinical negative neck (cN0) in patients with squamous cell carcinoma (SCC) of oral tongue, and to discuss the management of cervical lymph node for cN0 tongue SCC.
METHODSA total of 471 cervical lymph nodes derived from 25 patients with cN0 tongue SCC, including 263 lymph nodes in level III and 208 lymph nodes in level IV, were included in this study. All lymph nodes were re-examined by anti-cytokeratin (CK) immunohistochemical staining combined with semi-serial section per 500 microm.
RESULTSAmong the 25 cases, seven patients were confirmed harboring metastasis in 11 lymph nodes of level III, and no positive lymph node in level IV was detected by routine hematoxylin-eosin (HE) staining. 11 positive lymph nodes in level IIl, which confirmed by HE staining, were also detected by immunohistochemical staining with CK combined with semiserial section. Among the 460 cervical lymph nodes in which HE staining did not show metastasis, only one lymph node in level III harboring a 2.0 mm x 1.5 mm micrometastasis was detected by immunohistochemical staining with CK, and no positive lymph node in level IV was detected by immunohistochemical staining with CK.
CONCLUSIONThe frequency of occult metastasis in level IV was very low, so it seemed unnecessary to dissect level IV for all patients with cN0 tongue SCC.

OBJECTIVETo study the causes of orchiectomy in different age groups.
METHODSWe retrospectively reviewed the clinical data about 291 cases of orchiectomy performed between March 1993 and October 2014 and analyzed the causes of surgery and their distribution in different age groups.
RESULTSThe main causes of orchiectomy were testicular torsion (45.8%), cryptorchidism (32.5%) and testicular tumor (16.9%) in the patients aged 0-25 years, testicular tumor (42.4%), cryptorchidism (25.9%) and tuberculosis (10.6%) in those aged 26-50 years. Prostate cancer was the leading cause in those aged 51-75 years (77.6%) or older (84.0%)), and testicular tumor was another cause in the 51-75 years old men (10.2%). Prostate cancer, testicular tumor, cryptorchidism, and testicular torsion were the first four causes of orchiectomy between 1993 and 2009. From 2010 to 2014, however, testicular tumor rose to the top while prostate cancer dropped to the fourth place.
CONCLUSIONThe causes of orchiectomy vary in different age groups. The proportion of castration for prostate cancer patients significantly reduced in the past five years, which might be attributed to the improvement of comprehensive health care service.

OBJECTIVETo compare the impact of various types of neck dissection on postoperative shoulder function.
METHODSThe shoulder functions of 66 patients with oral squamous cell carcinoma (OSCC) and cN0 necks who underwent various types of neck dissection were evaluated by Constant's shoulder function test and neck dissection impairment index at least 12 months after surgery.
RESULTSThe patients with accessory spinal nerve reserved had better shoulder function than those with accessory spinal nerve resected. In the group with accessory spinal nerve reserved, the patients receiving selective neck dissection (SND) showed better shoulder function than those with modified radical neck dissection (MRND). The shoulder dysfunction and pain arising from SND were minor in patients with selective neck dissection.
CONCLUSIONSThe shoulder function after SND was superior to those after RND and MRND.

OBJECTIVETo evaluate the feasibility of 3-Dimensional (3-D) model reconstruction of penis and surrounding structures based on magnetic resonance images, which may provide the model building method for modeling surgery of individual penoplasty.
METHODSMagnetic resonance (MR) images of penis with different imaging parameters were evaluated. With the surface rendering construction, the 3D virtual model was established by Amira software.
RESULTSThe anatomical details imaging is better in T2-weighted fast spin-echo images with 3.0 mm slice thickness. The established model based on the MR images can show the soft-tissue, suspensory ligament of the penis. The suspensory ligament stretches between the pubic symphysis and the corpora cavernosa. The penile roots attach to inferior ramus of pubis.
CONCLUSIONSMR imaging provides enough anatomical information for modeling. It can be used for the development of model surgery system of individual penoplasty.

OBJECTIVETo develop toxin targeting vascular endothelial growth factor receptor II (VEGF-II/KDR) fused with a KDR-binling peptide screened from peptide library.
METHODSBy affinity to KDR molecular which expressed specifically by new born vascular endothelial cell, peptides to KDR were screened from C7 peptide library by phage display. Among them, a peptide binding to KDR with high affinity termed as P5 was selected and fused to the N-terminal of Shiga toxin subunit A (StxA). The protein (P5-StxA) was expressed in E. coli.
RESULTSELISA and Western blot were applied to characterize the binding interaction between the fusion protein, P5-StxA and KDR. Cytotoxicity assay showed that P5-StxA maintained similar toxicity to cell as StxA. In the model of angiogenesis, P5-StxA inhibited selectively VEGF-induced growth of preexisting vessels of the chick chorioallantoic membrane.
CONCLUSIONThese studies demonstrate the small peptide, P5, maybe be used as carrier of toxin targeting to KDR.

OBJECTIVETo report 2 cases of prostatic abscess and review the current characteristics of prostatic abscess in China.
METHODSTwo cases of prostatic abscess were reported, and a meta-analysis was made of the literature from the Chinese National Knowledge Infrastructure database and Wanfang Data in recent 10 years.
RESULTSBoth the cases had a high glucose level, and one of them had received instrumental examination of the lower urinary tract prior to the problem, both with difficult defecation, severe perineal pain and high fever, with normal peripheral white blood cell count and negative urine routine. One case of abscess was confirmed by MRI, ruptured into urethra and cured by antibiotics. The other case was confirmed by transrectal ultrasound and CT and cured by transrectal ultrasound guided needle aspiration. Meta-analysis showed that the predisposed factors were diabetes mellitus, the indwelling catheter and instrumentation of the lower urinary tract. Major pathogens were staphylococci aureus and Escherichia coli. For most patients, the diagnosis was mainly established by ultrasonography and the treatment included needle aspiration or surgery.
CONCLUSIONThe clinical symptoms of prostatic abscess are not typically presented and the differential diagnosis may be difficult. Imaging investigation is helpful, and transrectal ultrasonography can be used for both diagnosis and treatment.

OBJECTIVETo investigate the impact of preoperative radiochemotherapy on postoperative complications in patients with mid-low rectal carcinomas.
METHODSClinicopathologic data of T3 and T4 patients with mid-low rectal carcinomas in the Department of Colorectal Surgery at the Changhai Hospital of The Second Military Medical University from January 2009 to December 2010 were analyzed retrospectively. This cohort included 81 patients treated with preoperative radiochemotherapy followed by operation(radiochemotherapy group) and 93 cases who underwent surgery alone(control group).
RESULTSBoth resection rate and sphincter preservation rate were higher in the radiochemotherapy group(100% and 86.4%) than those in the control group(94.6% and 73.1%), and the difference in sphincter preservation rate was statistically significant(P=0.039). There were no significant differences in the mean operative time [(130±15) min vs.(125±20) min, P>0.05] and mean amount of bleeding [(100±15) ml vs. (95±10) ml, P>0.05] between the two groups. The overall incidence of postoperative complications was similar(9.9% vs. 9.7%, P>0.05).
CONCLUSIONSPreoperative radiochemotherapy can significantly increase sphincter preservation rate of mid-low rectal carcinomas, and does not increase the difficulty in surgical procedure and postoperative complications.
