Objective To investigate the effect of mindfulness on anxiety and depression of gynecological oncology patients.Methods Using objective methods,80 patients with gynecological oncology were divided to the usual care group and mindfulness training group according to random number table,40 cases in each group.The self -rated anxiety scale and self -rated depression scale were used to compare the effects at three times.Results There were 3 patients lost and 77 patients were analyzed finally.The ANOVA showed that there were significant differences on anxiety and depression scores of SAS (F =4.614,P =0.035) and SDS (F =4.070,P =0.044) between the two groups,and the scores of SAS (F =15.115,P <0.001) and SDS (F =7.034,P =0.002) had interaction effects. Conclusion Mindfulness can adjust the psychology state of gynecological oncology patients and decreased the level of anxiety and depression.

Objective To investigate the bettertherapeutic method and clinical efficacy of discoid meniscus injury under arthroscope.Methods Forty-one patients with discoid meniscus injury were selected as our subjects from Nov.2011 to Feb.2013,who were treated by arthroscopic surgery and performed with meniscus plasty.Thirt-eight patients were received ultra Fast-fix meniscal repair system.Joint function exercises were performed on bed within 1 month after operation.Incomplete weight bearing were performed after 1 month postoperation.After 3 month postoperation,they were permitted for full weight bearing.Results All patients were treated successfully with surgery and no postoperative complications occurred.The patients were followed up from 3.0 to 18.0 months and average was 10.5 months.The preoperative Lysholm scores were(68.28 ±8.04)) lower than that at the postoperation (88.17 ± 7.49)) and the difference were significant (t =11.59,P ＜ 0.05).Furthermore,according to Ikeuchi criterion,the outcomes were 28 cases with excellent,10 cases with good and 3 cases with general rank.Conclusion Discoid meniscus plasty and suture under arthroscope is proved to be a better approach with less trauma,recovery quickly and fewer complications.It should be a preferred method for discoid meniscus injury.

Objective:To explore the surgical techniques in posterolateral mini-incision total hip arthroplasty and clinical effcacy.
Methods:A total of 94 patients (98 hips) had posterolateral mini-incision total hip arthroplasty, from December 2006 to December 2008, and were randomly divided into a posterolateral mini-incision total hip arthroplasty group (Group A) and a conventional group of posterolateral incision for total hip arthroplasty (Group B). Forty-nine patients (50 hips) in Group A had posterolateral small incision total hip arthroplasty [26 males, 23 females, between 37.0 and 95.0 years (average 68.9 years), body mass index (BMI) between 20.3 and 29.7 (average BMI 25.4)]. Forty-ifve patients (48 hips) in Group B had the conventional posterolateral incision [27 males, 18 females, between 45.0 and 92.0 years (average 69.7 years), BMI between 18.7 and 34.1 (average BMI 26.9)]. The incision length, blood loss, drainage, operation time, and postoperative Harris scores were compared between the 2 groups.
Results:The incision length was 6.0~10.5 (average length 7.4) cm, average blood loss was 387.6 (140.0~1000.0) mL, average drainage was 143.1 (63.0~375.0) mL, average blood transfusion was 77.6 (0~400.0) mL, average operation time was 84.6 (63.0~130.0) min, and vitalock abduction angle imaging after the operation was 41.6° (averagely 38.0°~57.0°) in Group A. The incision length was 15.0~23.0 (average length 20.0) cm, average blood loss was 513.1 (210.0~1350.0) mL, average drainage was 152.3 (70.0~520.0) mL, average blood transfusion was 142.2 (0~800.0) mL, average operation time was 84.0 (71.0~115.0) min, and postoperative radiographic acetabular cup abduction angle was 42.3° (37.0°~54.0°) in Group B. The follow-up showed that the prosthesis of the 2 groups was in a good position, Harris score was significantly improved with no complications after total hip arthroplasty in the 2 groups.
Conclusion:With the correct selection of indications and adept operation skills and other circumstances, posterolateral mini-incision total hip arthroplasty may do little damage to the soft tissue with a small scar on the skin. The imaging evaluation after the operation and the Harris score show no difference between the 2 groups. Patients are satisfied with their joint function and postoperative recovery.

BACKGROUND: Hydrogen sulfide signaling has been proved to promote distraction osteogenesis; however,the underlying mechanism remains unclear.OBJECTIVE: To evaluate the relationship between hydrogen sulfide and hypoxia-inducible factor-1α (HIF-1α)during the osteogenesis of rat bone marrow mesenchymal cells under tensile stress.METHODS: 2000 μ strain was loaded on the in vitro cultured rat bone marrow mesenchymal cells by a four-point bending apparatus, and hydrogen sulfide donor or HIF-1α inhibitor was adopted in the tensile unit. Subsequently, the levels of osteogenic markers were detected.RESULTS AND CONCLUSION: Exogenous hydrogen sulfide signaling could promote the osteogenesis of rat bone marrow mesenchymal cells under tensile stress. However, this promotion was obviously eliminated when the endogenous HIF-1α expression was inhibited.These results show that hydrogen sulfide signaling system promotes the osteogenesis of rat bone marrow mesenchymal cells under tensile stress probably through HIF-1α.

However, tissue engineering provides a new way for repairing articular cartilage defects. Present research focus has come down to the following issues: the stability of cell characters and phenotypes during mass amplification of seed cells, the control of directional differentiation, the combination of multi-scaffold materials, the synergistic effect of multi-growth factors, the gene transfer technology for maintaining the expression of growth factors, etc. This article reviews the advances in seed cells, scaffold materials, growth factors of articular cartilage tissue engineering, pointing out their advantages and disadvantages as well as the research direction in the future.

Background Activation of serum complement system is involved in the pathological process of uveitis and open angle glaucoma.Pathogenesis and pathological characteristics of Posner-Schlossman syndrome (PSS) are similar to uveitis and open angle glaucoma.However,etiology of PSS remains unelucidated.The activation complement in PSS patients' serum is rarely reported.Objective The aim of this study was to investigate the activation of serum complement in PSS patients for PSS pathogenesis.Methods A prospective case-controlled study was designed.The peripheral blood simples of 79 PSS patients were collected from Shenzhen Eye Hospital during December 2013 to December 2015,and the peripheral blood simples were obtained from 83 unrelated healthy blood donors as healthy control group.Immuno-scatter turbidmetry was adopted to detect the common activated components in complement pathway in each group including complement C3 (a vital intersection molecule in the three pathways),C4 (the vital molecule both the complement classical and lectin pathways),split products C3a,soluble membrane attack complex (sC5b-9),C 1q (complement classical pathway),L-ficolin (complement lectin pathway),complement factor Bb (complement alternative pathway),IgG,IgA and IgM.The correlation between serum C3a content and sC5b-9 content in PSS group was analyzed.The serum contents of fabric binding protein 2 (FCN2) (a marker of serum classical pathway),factor Bb (a marker of complement alternative pathway),C3a (the common activation products of three complement activation pathways),and sC5b-9 were assayed by ELISA.This research protocal was approved by Shenzhen Eye Hospital and written informed consent was obtained from each PSS patient prior to any medical examination.Results Compared with normal control group,the serum levels of C3,C4,C3a,sC5b-9,C1q,FCN2,IgG,IgA and IgM were significantly higher in PSS group (Z =-4.743,-2.913,-1.985,-2.620,-2.062,-2.500,-7.010,-6.327,-3.652,all at P ＜ 0.05).The serum complement factor Bb level was 13.87 (9.24,32.00) μg/ml in PSS group,which was significantly lower than 20.51 (12.90,33.50) μg/ml in normal control group (Z =-2.515,P =0.012).Serum C3a content was positively correlated with the serum sC5b-9 content in PSS group (rs =0.832,P＜0.001).Conclusions The serum complement system is activated in PSS patients.Complement alternative pathway,classical pathway and lectin pathway might all be involved in the activative process of complement system.

Objective To explore the effect of glucocorticoid receptor(GR)expression in rat hippocampus on cognitive function after traumatic brain injury(TBI). Methods The TBI model wag established in rats.Then,immunohistochemistry and Western blot were used to detect the GR expression and evaluate its relation with cognitire dysfunction by Morris water maze. Results Expression of hippocampal GR was down-regulated 4-10 days after TBI.Morris water maze test showed significant impairment of the cognitive function in rats. Conclusion There is correlation between expression change of hippocampal GR and cognitive dysfunction.

Objective To investigate the expression and significance of calcyclin binding protein (CacyBP)in the brain of rat model of traumatic brain injury(TBI).Methods Sixty 60 male SD rats were divided randomly into normal control group (n=10) and TBI group (n=50).The TBI model was created by using lateral head rotation device and subdivided into 6 h,24 h,72 h,7 d and 14 d group (10 rats per group).The expression and distribution of CacyBP in the rat brain was investigated immunohistochemically.The presence of the brown stained particles was considered aspositiveand lack of the stained particles agnegative. Results CacyBP was mainly distributed in the hippocampus,dentate gyrus and cortical neuron cytoplasm.Compared with the high level expression of CacyBP in the normal control group,the expression of CacyBP was decreased to the lowest in the rat brain at 6 h post TBI (P<0.01),became stronger gradually at 24 hours and recovered to normal at day 14,with no statistical difference compared with normal control group (P>0.05). Conclusion The lowest level expression of CacyBP after TBI indicates that CacyBP may play an important role in development of brain injury under effect of difierent mechanisms.

ObjectiveTo compare orthotopic liver transplantation (OLT)and combined liverkidney transplantation (CLKT) in the treatment of severe hepatitis B.MethodsIn this study 52 patients of severe hepatitis B were allocated to OLT (40 cases) or CLKT( 12 cases) at our department from Jan.2001 to Sep.2005.The perioperative complications and the result of follow-up were analyzed.ResultsThe preoperative renal functions in CLKT cases were severer than that in OLT cases.Postoperative severe infection was more common in CLKT cases than that in OLT cases.In OLT group 28 patients (70％)suffered from early posttransplant renal dysfunction,among them 11 patients needed dialysis,whilst there were 2 (16.7％ ) patients who needed dialysis in CLKT group (P ＜0.01 ).The posttransplant mortality in OLT group was 40％ ( n =16),significantly higher than that in CLKT ( 16.7％,n =2) ( P ＜ 0.01 ).In OLT group,9 cases developed severe renal failure and died.No one died of renal failure in CLKT group.ConclusionsThe prognosis is more favorable to perform CLKT in patients who suffered from severe hepatitis B with chronic renal dysfunction before transplantation.

Objective To analyze the clinicopathological factors on the prognosis and investigate the necessity of adjuvant chemotherapy for patients with stage Ⅱ colorectal cancer.Methods The clinical data of 255 patients with stage Ⅱ colorectal cancer who were admitted to the First Affiliated Hospital of Sun Yat-Sen University from January 2000 to December 2005 were collected.The survival curve was drawn by Kaplan-Meier method,and the survival rate of the patients were analyzed by Log-rank test.Factors influencing the survival were analyzed by Cox regression model.Results All patients were followed up till April 23,2010,and the mean time of follow-up was (63 ± 22)months.The median survival time was 63 months.The 5-year and tumor-free survival rates were 85.3％ and 83.7％,respectively.The 5-year overall and tumor-free survival rates of patients without preoperative bowel obstruction or perforation were 86.9％ and 85.6％,which were sigaificantly higher than 72.7％and 68.4％ of patients with preoperative bowel obstruction or perforation(x2 =4.546,4.573,P ＜ 0.05 ).The 5-year overall and tumor-free survival rates of patients with negative resection margin were 85.5％ and 83.9％,which were significantly higher than 75.0％ and 75.0％ of patients with positive resection margin(x2 =7.020,6.009,P ＜ 0.05 ).The result of multivariate analysis revealed that preoperative bowel obstruction or perforation were the independent risk factors for patients with stage Ⅱ colorectal cancer(Wald =4.477,relative risk =2.371,95 ％ confidence interval:1.066-5.275,P ＜ 0.05 ).The 5-year overall and tumor-free survival rates were 87.3％ and 86.0％ for patients who received adjuvant chemotherapy,and were 82.2％ and 80.3％ for patients who did not receive adjuvant chemotherapy (P ＞ 0.05 ).Conclusions Preoperative bowel obstruction or perforation are independent risk factors for the survival of patients with stage Ⅱ colorectal cancer.Adjuvant chemotherapy could not improve the prognosis of patients with stage Ⅱ colorectal cancer.
