OBJECTIVETo investigate the intra-vaginal ejaculation latency time (IELT) of varicocele patients, the influence of spermatic vein ligation on IELT, and the relationship of Visual Analogue Score (VAS) with IELT.
METHODSWe selected 112 males who had regular sexual life after spermatic vein ligation and conducted follow-up visits for 6 months. According to preoperative IELT, we divided the patients into an IELT < or = 2 min group and an IELT > 2 min group, and compared their IELT, VAS and Chinese Index of Sexual Function for Premature Ejaculation-5 (CIPE-5) scores before and 6 months after operation.
RESULTSFollow-up was accomplished in 81 of the patients, 18 in the IELT < or = 2 min group and 63 in the IELT >2 min group. Compared with the baseline, IELT was significantly prolonged postoperatively in both the IELT < or = 2 min group ([1.26 +/- 0.37] vs [4.53 +/- 1.69] min, P < 0.01) and the IELT >2 min group ([5.14 +/- 2.03] vs [7.69 +/- 4.51] min, P < 0.05); the postoperative CIPE-5 scores were remarkably improved in the former (11.27 +/- 3.52 vs 15.64 +/- 2.37, P < 0.05) but insignificantly in the latter group (20.42 +/- 4.65 vs 21.83 +/- 5.49, P > 0.05); the postoperative grades of the CIPE-5 scores showed significant differences in both groups (chi2 = 6.353, P = 0.042 and chi2 = 3.910, P = 0.048); the postoperative VAS was markedly increased (3.18 +/- 0.92 vs 1.56 +/- 0.83 and 3.24 +/- 0.95 vs 1.74 +/- 0.79, P < 0.05), with significant differences in the grades of VAS in both groups (chi2 = 4.433, P = 0.035 and chi2 = 10.088, P = 0.001). The variation of VAS was negatively correlated with that of IELT in both groups (r = -0.572, P < 0.01 and r = -0.465, P < 0.05).
CONCLUSIONVaricocele may be one of the causes of premature ejaculation, and some of the varicocele patients with IELT < or = 2 min may benefit from spermatic vein ligation. Improved VAS is negatively correlated with prolonged IELT. The relationship between varicocele and premature ejaculation deserves further studies.

OBJECTIVETo investigate the role of CXC chemokine receptor 3 (CXCR3) in bleomycin-induced lung injury by using CXCR3 gene deficient mice.
METHODSSex-, age-, and weight-matched C57BL/6 CXCR3 gene knockout mice and C57BL/6 wide type mice were challenged by injection of bleomycin via trachea. Lung tissue was stained with HE method. Airway resistance was measured. Bronchoalveolar lavage (BAL) was performed using phosphate buffered saline twice, cell number and differentials were counted by Diff-Quick staining. Interleukin (IL)4, IL-5, IL-12p40, and interfon-y in BAL fluid and lung homogenate were measured by enzyme-linked immunosorbent assay. Unpaired t test was explored to compare the difference between two groups.
RESULTSOn day 7 after bleomycin injection via trachea, CXCR3 knockout mice were protected from bleomycin-induced lung injury as evidenced by fewer accumulation of inflammatory cells in the airway and lung interstitium compared with their wild type littermates (P < 0.05). Airway resistance was also lower in CXCR3 knockout mice compared with wild type mice (P < 0.01). Significantly lower level of inflammatory cytokines release, including the altered production of IL-4 and IL-5 both in BAL fluid and lung tissue was seen in CXCR3 knockout mice than in wild type mice (both P<0.05).
CONCLUSIONCXCR3 signaling promotes inflammatory cells recruiting and initiates inflammatory cytokines cascade following endotracheal bleomycin administration, indicating that CXCR3 might be a therapeutic target for pulmonary injury.

OBJECTIVEThis study aimed to explore the scene-trait coping style of military rescuers in Wenchuan earthquake in an effort to provide scientific evidences for mental intervention program for Chinese military personnel.
METHODSBy cluster sampling, a total of 151 military rescuers and 331 control servicemen were administered the military personnel scene-trait coping style scale (MPSTCSS).
RESULTSAll active coping factor scores, and passive coping factor scores of affection, health and economy in the rescuer group were significantly higher than those in control group (P < 0.05). The 21-above age subgroup, the 3-year plus service subgroup, and the officer subgroup had significantly higher active coping factor scores on military tasks, military experience and personal development than those of the 21-below age subgroup, 3-year minus service subgroup and the soldier subgroup, respectively (P < 0.05 or P < 0.01).
CONCLUSIONThe earthquake relief servicemen can cope with stressful situations better than control group by taking active coping style. The officers, servicemen older than 21 years, and servicemen with more service duration than 3 years could usually take active coping style.

OBJECTIVETo investigate the differential expressions of nucleolin in invasive cervical squamous cell carcinoma, cervical intraepithelial neoplasms (CIN) and normal cervical epithelial tissues and explore the role of nucleolin in the carcinogenesis and progression of cervical squamous cell carcinoma.
METHODSFifty specimens of invasive cervical squamous cell carcinoma, 65 specimens of CIN, and 60 adjacent normal cervical epithelial tissue specimens were examined immunohistochemically for nucleolin expression. The correlation of nucleolin expression levels with histological grades of invasive cervical squamous cell carcinoma and CIN were analyzed.
RESULTSThe specimens of invasive cervical squamous cell carcinoma showed a significantly higher positivity rate for nucleolin expression than CIN and normal cervical epithelial tissues, and the rate in CIN tissues was significantly higher than that in normal cervical epithelial tissues (P<0.01). The expression level of nucleolin was significantly higher in invasive cervical squamous cell carcinoma than in CIN and normal cervical epithelia tissues, and higher in CIN than in normal cervical epithelia tissues, whose immunostaining scores were 7.6±0.3, 6.1±0.2, and 3.0±0.2, respectively (P<0.01). The mean nucleolin immunostaining score was significantly higher in poorly and moderately differentiated than in highly differentiated cervical squamous cell carcinoma (7.9 vs 7.1, P<0.01), and higher in high grade CIN than in low grade CIN tissues (6.0 vs 4.0, P<0.01).
CONCLUSIONSOverexpression of nucleolin plays an important role during carcinogenesis of cervical squamous cell carcinoma and is positively correlated with tumor progression of CIN and cervical squamous cell carcinoma.

OBJECTIVETo investigate the role of sulfated tyrosine in regulating the activity of tyrosylprotein sulfotransferases (TPST) 1 and TPST2.
METHODSConstructs of TPST 1 and TPST2 were amplified by polymerase chain reaction (PCR), then fused into immunoglobulin G1 Fc region. All the variants in which sulfated tyrosines were mutated to phenylalanine were made by the PCR-based Quick Change method and confirmed by sequencing the entire reading frame. Small hairpin RNA (shRNA) constructs-targeting nucleotides 259-275 of TPST1 and nucleotides 73-94 of TPST2 were generated and subcloned into pBluescript. Human embryonic kidney (HEK) 293T cells were transfected with these plasmids. One day later, cells were split: one part was labeled with 35S-cysteine and methionine or 35S-Na2SO3 overnight, the second part was used for 125I labeled binding experiment, and the third part was retained for binding and flow cytometry.
RESULTSTyrosines at position 326 of TPST1 and position 325 of TPST2 were sulfated posttranslationally. Tyrosine sulfation of TPSTs was effectively inhibited by sulfation inhibitors, including specific shRNAs and non-specific NaCIO3. shRNAs reduced the sulfation of C3a receptor and C5a receptor, and partially blocked the binding of these two receptors to their respective ligands.
CONCLUSIONSThe activities of TPSTs were regulated by tyrosine sulfation. Inhibition of sulfotyrosine decreases the binding ability of C3a receptor and C5a receptor to their respective ligands.

The objective of this study was to elucidate the correlation of killer immunoglobulin-like receptor (KIR) gene diversity with nasopharyngeal carcinoma (NPC) in the Chinese southern Han population. KIR genotyping of peripheral blood samples from 67 patients with NPC and 77 randomly-selected healthy controls was performed by PCR-SSP, the relative risk (RR) value was calculated by means of Wolf method. The results showed that the KIR2DL3 gene frequency in NPC patient group was significantly lower than that in healthy controls (χ²>3.84, p < 0.05, RR = 0.08), whereas the KIR2DS5 and KIR2DL5B gene frequencies in patient group were significantly higher than those in healthy controls (χ²>3.84, p < 0.05, RR > 1), the other KIR gene frequencies were no statistically different between two groups. It is concluded that the KIR2DL3, KIR2DS5 and KIR2DL5B genes may be correlated with pathogenesis of NPC in the Chinese southern Han population.
