Objective To describe the operative procedures.fracture patterns and clinical outcomes of treatment of posterior column tibial plateau fractures.Methods From February 2005 to August 2006,36 patients with posterior column tibial plateau fracture were operated on.Twenty patients were treated with open reduction and buttress plate fixation via a posterior approach.They were 13 males and 7 females,with a mean age of 38.5(ranging from 29 to 52)years.The other 16 patients were operated on via anterior plus posterior approaches.They were 11 males and 5 females,with a mean age of 37.3(ranging from 27 to 49) yeam. Results All were followed up for an average of 14.5(ranging from 12 to 15)months.All frac- tures got united with an average radiographic bone union time of 15.7(ranging from 11 to 16)weeks and an average full weight-bearing time of 17.6(range from 13 to 21)weeks.The mean HSS(The Hospital for special surgery)score of all these patients at 12 months postoperatively were 83.4(ranging from 68 to 92). There were 1 case of inferior medial genicular vessel injury during the operation,1 wound dehiscence and 1 partial incision necrosis postoperatively which were all eventually healed with conservative treatments.Three cases of numbness within the posterior lower part of the calf occurred postoperatively.No screw toggle,slide, dislodging or fixation failure was found during follow-up.There were no significant differences both between TPA and PA on radiographies and between immediately after operation and 12 months psstoperatively. Conclusion Open reduction and internal fixation with buttress plates via a posterior or anterior plus posterior approaches is appropriate for treatment of posterior column tibial plateau fractures.

Objective:To explore the relationships between perfectionism and coping strategies among graduate students.Methods:396 college graduate students completed the COPE (the Coping Inventory),FMPS (Frost's Multidimentional Perfectionism Scale) and General Self-efficacy Scale.Results:①Significant positive correlations were found between adaptive perfectionism and self-efficacy,while negative correlations between doubt about actions in maladaptive perfectionism and self-efficacy;② Regression analysis indicated predictability of perfectionism and self efficacy to coping strategies.Self-efficacy still had significant predictability after perfectionism and its sub-dimension were controlled.Conclusion:Self-efficacy plays an important mediation role between perfectionism and coping strategy.

Objective To investigate the predictive value of breast cancer susceptibility gene 1 (BRCA1) and class Ⅲβ-tubulin protein expression in tumor tissue for the efficacy of taxol and cisplatin combined chemotherapy (TP) in stage Ⅲβ/Ⅳ non-small cell lung cancer(NSCLC) patients. Methods A total of 92 stage Ⅲβ/Ⅳ NSCLC patients were recruited with 87 patients evaluated. Bronchoscopy or lung puncture tumor biopsy samples were obtained with BRCA1 and class Ⅲβ-tubulin protein expression examined immunohistochemically before chemotherapy. The patients were randomly assigned to be received 4 to 6 cycles of TP chemotherapy regiments and followed up until death or lost. Response rate (RR) , overall survival (OS) and time to tumor progression (TTP) were assessed. Results Among the 87 evaluated patients, the positive expression rates of BRCA1 and class Ⅲβ-tubulin were 57. 5% (50/87) and 48. 3%(42/87) respectively. There was no significant difference in clinical characteristics among patients with different positive expression rate. According to different expression of BRCA1 and class Ⅲβ-tubulin, the patients were divided into four groups: group A (low expression of both BRCA1 and class 1 p-tubulin) ,group B (high expression of both BRCA1 and class Ⅲβ-tubulin) , group C (high expression of only BRCA1) and group D (high expression of only class Ⅲβ-tubulin). The RR was higher in group A than other three groups (60. 7% , 34. 8% , 9/19 and 6/17 respectively). The OS and TTP were longer in group A than other three groups [OS: (539. 4 ± 17. 6) days, (267. 2 ± 20. 5) days, (325. 6 ± 24. 1) days and (283.7±26.2) days respectively ; TTP: (256. 9 ± 28. 4) days, (143.8±17.6) days, (179. 3 ± 19. 8)days and (152. 6 ±23. 5) days respectively]. There were no significant differences among the other three groups. Conclusions The expression level of BRCA1 and class Ⅲβ-tubulin in tumor tissue is probably a predictor for the efficacy of TP chemotherapy in NSCLC patients. TP chemotherapy is more suitable for the NSCLC patients with lower expression of both BRCA1 and class Ⅲβ-tubulin. Our study may provide a new sight for tailored chemotherapy in NSCLC patients.

Objective To compare the esophageal acid and alkaline exposure characteristics of patients with cardia carcinoma after proximal gastrectomy or total gastrectomy.Method A total of 77 patients of cardia carcinoma who underwent radical resection from Sep 2007 to Sep 2011 in our hospital were retrospectively reviewed.24 hour esophageal pH monitoring were performed in all patients.Result Patients were divided into three groups:group TG had total gastrectomy (n =25),group PP had proximal gastrectomy with pyloroplasty (n =33),group NP had proximal gastrectomy (n =19).It revealed that indicators of acid reflux including the overall time length of acid episodes,＞ 5 min times of acid episodes,duration of longest acid episodes,time length of pH ＜ 4.00 and the DeMeester Scores in group NP were significantly higher than in group PP(U =32,P ＜ 0.01 ; U =35,P ＜ 0.01 ; U =23,P ＜ 0.01 ; U =39,P ＜0.01 ;U =49,P ＜0.01 respectively).Only alkline reflux was observed in group TG.The total times of alkaline episodes in PP group was significantly lower than in group TG(U =52,P ＜0.01) and group NP (U =182,P ＜0.01).＞5 min times of alkaline episodes in group TG was larger than in group PP,and that in group PP was larger than in group NP(P ＜0.01).Duration of longest alkaline episodes and total period of pH ＞7.00 in group PP was significantly higher than in group TG(U =125,P ＜ 0.01 ; U =143.5,P ＜ 0.01),and that in group TG was higher than in group NP(U =23.5,P ＜ 0.01 ; U =14,P ＜ 0.01).Conclusions Alkaline reflux deserves more attention in evaluating esophageal reflux in patients with cardia carcinoma after resection.Pyloroplasty is not helpful to relieving esophageal acid episodes while causing severe alkaline reflux.

Objective To evaluate the effect and clinical value of open surgery combined ultrasound-guided Mammotome in the treatment of multiple breast lumps. Methods Four hundred and forty-four patients in our hospital from Jan. 2006 to Jun. 2008 were divided into 3 groups, who underwent classical open surgery, ultrasound-guided Mammotome operation, or combined therapy respectively and followed by post-operation visits reguarly. The operation effects were compared between the 3 groups. Results Compared with the classical open surgery, combined therapy had no difference in time of procedure and procedural bleeding, but had lower incidence of local skin, better incision condition and higher satisfaction of patients. Compared with ultrasound-guided Mammotome operation, combined therapy took less time in procedure, and in the same time had less procedural bleeding, lower post-operation complication and higher patients satisfaction. Conclusions Combined therapy has high complete removal rate, low post-operation complication as well as cosmetic effect. It has special advantages over the other two kinds of surgery, so it has wide clinical application.

OBJECTIVETo summarize the clinical features, diagnostic and therapeutic experiences of colorectal Non-Hodgkin's lymphoma (NHL).

METHODSClinical data of 32 patients with colorectal NHL admitted to our hospital from January 1988 to December 2006 was retrospectively analyzed.

RESULTSThis study included 22 B-cell NHL and 10 T-cell NHL cases. In the B-cell NHL group, the male: female ratio was 14:8 and the median age was 60.5 years. In the T-cell NHL group, the male: female ratio was 5:5 and the median age was 31.0 years. The ileocecal region was most frequently involved in both groups, which accounted for 77.3% and 60.0% of the B and T group respectively. The common clinical manifestations included abdominal pain, weight loss, and abdominal mass. Of the 14 cases of B-cell NHL with definite subtype classifications, 64.3% were of the Diffuse Large B-cell Lymphoma (DLBCL) type. Among the 22 B-cell NHL, 40.9% were with localized diseases (stage I-II1), while all 10 patients in T-cell NHL group were in stage IV with 3 patients complicated with massive GI bleeding and 4 with perforation. All patients of B-cell type received chemotherapy utilizing mainly CHOP after surgical resection. After a median follow-up of 55 months, the disease-free survival was rate 88.2%. Among the T-cell NHL group, 8 out of 10 patients underwent surgery and chemotherapy was given to all those who could tolerate it. Five patients died within 2 months after surgery. It's known that 3 patients were still alive after 23 months.

CONCLUSIONSThe ileocecal region is the most frequently involved site of the colorectal NHL. The histology is usually B-cell type with a majority being DLBCL. Currently R-CHOP chemotherapy after the surgical resection is the principal treatment modality. Patients of B-cell type have a better prognosis while the prognosis of T-cell NHL is poor. Therefore more aggressive diagnostic and therapeutic approaches are recommended for T-cell NHL patients. The prospective of organ preservation treatment for colorectal NHL is still in need of further investigations.

BACKGROUNDHigh uric acid (UA) levels and metabolic syndrome (MS) are risk factors for atherosclerotic diseases. Brachial-ankle pulse wave velocity (baPWV) is a valid and reproducible measurement by which to assess arterial stiffness and a surrogate marker of atherosclerosis. However, little is known about the relationship between them, especially in elderly Chinese with MS components who are at high risk for atherosclerotic diseases.

METHODSOne thousand and twenty Chinese subjects (159 women) older than 60 years of age (mean age (70.6 ± 5.7) years) with at least one MS component underwent routine laboratory tests, and baPWV measurements were analyzed.

RESULTSParticipants were divided into four groups by MS components. The mean age did not significantly differ among the MS component groups. We found that not only the diagnostic factors (blood pressure, body mass index (BMI), lipids, glucose) of MS but also baPWV, UA, insulin, homeostasis model of assessment for insulin resistence index (HOMAIR) levels increased, and high density lipoprotein (HDL)-C decreased with an increased number of MS components (test for trend P < 0.05). The association between UA and baPWV was observed after adjustment for gender, age, blood pressure, BMI, serum creatinine and high density lipoprotein, and insulin resistance (r = 0.186, P < 0.0001). There were increases in the odds ratios for the association between the number of components of MS, UA and baPWV, even after adjustment for traditional risk factors. However, after adjustment for insulin or HOMA-IR, there were no significant differences in the multivariate odds ratios among the number of MS components for UA.

CONCLUSIONSThe UA level is positively associated with baPWV and MS, but the association between UA and MS is dependent on insulin resistance. Furthermore, baPWV is independently associated with MS in our study population.
