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 explore the central mechanism of moxibustion on analgesic effect.

METHODSMale Wistar rats were screened by pain threshold value before making model, and 48 rats whose pain threshold was (250 +/- 25) g were selected. Twelve male Wistar rats were randomly selected as a normal group. For the rest rats the rheumatoid arthritis (RA) model was duplicated by raising in a windy, cold and wet environment combined with injection of Freund's complete adjuvant (FCA), and then they were randomly divided into a model group, a moxibustion group and a moxa volatile oil group, 12 rats in each group. The moxibustion and the moxa volatile oil igroup were treated with moxibustion and moxa volatile oil at "Shenshu"(BL 23) and "Zusanli"(ST 36), respectively, for 15 days. No interventions were added on the model group and the normal group. The pain threshold in Iinjured foot and the expression of hypothalamic POMC mRNA and PDYN mRNA in rats were observed.

RESULTSCompared with the normal group, the pain threshold and the expression of hypothalamic POMC mRNA and PDYN mRNA in the model group were increased (all P < 0.01). Compared with the model group, the pain threshold and the expression of hypothalamic POMC mRNA and PDYN mRNA in the moxibustion group were increased significantly (all P < 0.01), but no statistically significance in the moxa volatile oil group (P > 0.05). Compared with the moxa volatile oil group, the above-mentioned observative indices in moxibustion group were all increased significantly (all P < 0.01).

CONCLUSIONMoxibustion has obvious analgesic effect and its mechanism may be related to the increasing expression of hypothalamic POMC and PDYN mRNA through the warming effect of moxibustion.

BACKGROUND AND OBJECTIVEThe most effective therapy against renal cell carcinoma (RCC) is surgical treatment; however, there have been few large-scale studies that focused on the oncological outcome of this disease in China. The aim of the current study was to report the clinicopathological results and cancer-specific survival (CSS) rate in RCC patients after surgical treatment in our center.

METHODSWe retrospectively analyzed the clinicopathological data of 336 RCC patients who underwent radical or partial nephrectomy between 1999 and 2006. Of the 336 patients, 226 were male and 110 were female; the median age was 51 years. Univariate and multivariate analyses were conducted to identify the independent prognostic predictors for this cohort of RCC patients.

RESULTSDuring follow-up, the overall 5-year CSS rate was 81.4%. The 5-year CSS rates for patients with stage-I, -II, -III, and -IV RCC were 94.7%, 88.9%, 68.8%, and 19.3%, respectively. The patients with T1N0M0 (T1) and T2N0M0 (T2) tumors had similar survival curves. For patients with T1 category tumor, the survival rate did not differ significantly between the radical nephrectomy and nephron-sparing surgery groups. For the 21 patients with metastasis confined to the local lymph nodes, the 5-year survival rate was 31.6% after radical nephrectomy and lymph node dissection. For the 15 patients with vena caval tumor thrombus, the 5-year survival rate was 52.5% after radical nephrectomy and tumor thrombus extirpation. Multivariate Cox regression showed that stage was an independent predictor for CSS (hazard ratio, 3.359; P < 0.001).

CONCLUSIONSFor localized RCC, the oncological outcome of this cohort is comparable to that reported in the Western literature. For some patients with locally advanced RCC, aggressive surgical treatment can lead to better long-term survival. However, the prognosis of the patients with metastasis still needs to be improved.

OBJECTIVETo investigate the clinicopathologic features of primary nodal marginal zone B-cell lymphoma (NMZL).

METHODSHematoxylin-Eosin staining and immunohistochemistry were used to evaluate the histological and immunophenotypic characteristics of lymph node (LN) tissue in 22 NMZL cases. Additionally, interphase fluorescence in-situ hybridization (FISH) was carried out to detect the presence of t(11;18) (q21;q21)/API2-MALT1 and/or t(14;18)(q32;q21)/IGH-MALT1 in 9 cases.

RESULTSThe median age of the 22 patients was 62 (16 - 77) ys. The male-to-female ratio was 1.2:1. All patients exhibited asymptomatic lymphadenopathy with the cervical region as the most often site to be involved (n = 11), followed by axillary (n = 9), inguinal (n = 7), submandibular (n = 6), mediastinal (n = 4), supraclavicular (n = 2) and retroperitoneal lymph nodes (n = 1). The Ann Arbor stages were I/II in 13 (59%) cases and III/IV in 9 (41%). Immunohistochemical study showed a consistently strong expression of CD20 and an absence in the expression of CD3ε, CD10, CD21, CD23, CyclinD1 and BCL6 by the tumor cells in all the cases. Frequency of expression of CD5 and BCL2 were 39% (7/18) and 30% (3/14) respectively. Among the 9 cases performed with FISH, 2 cases harbored t(14;18)and another 1 case positive for t(11;18) and t(14;18). Complete follow-up data were available for 13 cases. The follow-up time was 6 to 44 months. 3 of them died. 3-year cumulative survival rate was 67%.

CONCLUSIONSNMZL patients are often elderly, which mainly present with multiple lymphadenopathy, rare involvement of extranodal organ and early stage. The diagnosis must be based on a combination of clinicopathologic features, especially those patients detected t(11;18) and/or t(14;18).

OBJECTIVETo investigate the safety and effect of nephron-sparing surgery (NSS) in treatment of T1a and T1b renal cell carcinoma.

METHODSRetrospective analyzed the clinical data of 101 patients with T1 renal cell carcinoma underwent NSS from November 1999 to December 2009.Including 79 male and 22 female with the mean age of 52.3 years (ranged 28 to 79 years). Based on tumor pathologic diameter, 101 patients were divided into T1a group with 62 patient and T1b group with 39 cases. Demographic, intraoperative, postoperative and follow-up data were compared between the 2 groups.

RESULTSThe operation were performed successfully in all the 101 cases. The mean operation time was (151 ± 80) min in group T1a and (158 ± 50) min in group T1b with no statistical difference (P = 0.32). The mean blood loss was (322 ± 596) ml in group T1a and (308 ± 239) ml in group T1b (P = 0.45). Postoperative follow-up ranged from 8 to 102 months with a mean of 38.4 months. One patient in T1b group died of distant metastasis 36 months after operation. Others were no tumor recurred.

CONCLUSIONNephron-sparing surgery is safe and effective for the treatment of T1a and T1b renal cell carcinoma.

OBJECTIVETo investigate the clinicopathologic features, pathogenesis, diagnostic criteria and the relationship between different classification models and prognosis in Chinese patients with DLBCL, and try to look for the most appropriate classification model to predict clinical prognosis and therapeutic responses for Chinese patients with DLBCL.

METHODS181 cases of Chinese DLBCLs diagnosed according to the WHO 2008 classification were collected. Standard two-step Envision method of immunohistochemical staining was used to assess the expressions of CD20, CD3ε, CD79a, CD10, Mum-1, Bcl-6, GCET-1, FOXP1 and Ki-67. The phenotypic classifications were assessed according to the standard of Hans model and Chan model. Data were analyzed by χ(2) test and Life Table survival analysis with the SPSS14.0 statistical package.

RESULTSThe ratio of male to female in this cohort was 1.26:1. The median age of all patients was 57 yrs with the average age of 53.5 yrs. Of 61 cases (33.7%) primarily showed lymph node involvement. Gastrointestinal tract as the most involved extra-nodal organ was observed in 43 cases (35.8%). All patients with complete clinical follow-up materials survived from 1 - 120 months. The patients showed a high risk for death in the initial one and half years. Three year survival rate was 49.7% (90/181). Three year survival of 44 cases received R-CHOP (Rituximab, cyclophosphamide, doxorubicin, vincristine, bolus) was 76.9% (20/26), whereas 61.9% (60/97) in 119 cases received CHOP alone, R-CHOP group showed better prognosis (P = 0.017). All cases expressed one or more pan B cell markers, such as CD20 (176/179, 98.3%) and CD79a (62/77, 80.5%). For Hans model, 78 cases were classified as GCB group, while 103 cases as Non-GCB group. The ratio of Non-GCB to GCB was 1.32 without difference on the survival (P > 0.05). For the Chan's algorithm, 68 cases belonged to GCB subgroup, while 113 cases non-GCB subgroup. The ratio of non-GCB to GCB was 1.66. GCB subtype showed much better prognosis than non-GCB subtype according to Life Table survival analysis (P < 0.05).

CONCLUSIONThe epidemiology and clinicopathologic features of Chinese DLBCLs were similarly with the western cases. Chan's algorithm was a significant tool to predict the cell origin and clinical biology of Chinese DLBCLs.

Objective To observe the prevalence, blood pressure change in prehypertensive population and associated cardiovascular risk factors. Methods Data from a prehypertensive cohort defined with the JNC-7 prehypertension diagnostic criteria were obtained in the employees of kailuan group during the health examination between 2006 to 2007 and the same population was revisited between 2008 to 2009 to observe the change of blood pressure and the associated determinants for blood pressure change. Results (1) There were 25 474 prehypertensives during the 1st visit and 8361 subjects developed hypertension during the 2nd visit (35. 3% in men and 23. 3% in women, 27. 2% with baseline blood pressure 120-129/80-84 mm Hg( 1 mm Hg =0. 133 kPa) and 43. 8% with baseline blood pressure 130-139/85-89 mm Hg, 34. 3% with risk factors and 19. 9% without risk factors). (2) Multiple logistic regression analysis showed that the baseline SBP, waist circumference, age, BMI, gender (male), DBP, TC, FBG, TG, LDL-C were the risk factors of blood pressure progression with a RR (95% CI) of 1. 052(1. 048-1. 056), 1.009(1.006-1.013), 1.023(1.021-1.026), 1.063(1.052-1.074), 1.554(1.442-1.675), 1.036(1.029-1.043), 1.064 (1.037-1.093), 1.043 (1.024-1.062), 1.041 (1.021-1.062) and 1.035 (1.000-1.072), respectively. Conclusion A third (32. 8% ) prehypertensive population progressed into hypertension after two years, baseline SBP, waist circumference, age, BMI, gender (male), DBP, TC, FBG, TG, LDL-C were the risk factors of predicting blood pressure progression.

Amino acid surfactants (AAS) have excellent properties such as low toxicity,antibacterial,mildness,and corrosion resistance. In recent years,they have been widely applied in the field of daily chemicals,food and pharmaceutical industry. It is pointed out that the structure at molecular level largely affects the physical and chemical properties of AAS materials. In this work,the structures of solid-state N-lauroyl-L-alanine (NLLA) including intermolecular interactions,molecular local dynamics and molecular assembly were investigated by a variety of solid-state nuclear magnetic resonance (SSNMR) techniques. Based on 2D 1H-1H double quantum-single quantum (2D 1H-1H DQ-SQ),1H-1H DQ sideband pattern and molecular simulation,it was found that there was a stable intermolecular hydrogen bond formed between the carboxyl units of two NLLA molecules. Combined with the study of 2D frequency switched Lee—Goldberg heteronuclear correlation (2D 13C-1H FSLG-HETCOR) and 13C T1,another type of hydrogen bond was probed,which existed between amide units of neighboring molecules. In addition,the conformation of alkyl chain ends was investigated. According to 1D 13C{1H}cross polarization/magic angle spinning (CP/MAS) and 2D 13C-1H FSLG-HETCOR spectra,it was revealed that the alkyl-chain ends had both gauche and trans conformations. Moreover,the trans conformation showed two distinct 13C chemical shifts,originated from two NLLA molecular assembly forms. Accordingly,two NLLA molecular assembly structures were suggested which were transoid form and cisoid form. This work provided a SSNMR investigation strategy for characterizing the molecular local structure and dynamics of AAS materials,which helped task of researching and developing materials with improved chemical and physical properties.
