Objective To detect the methylation status of CDH1 3 gene promoter in colon cancer by using methylation-specific polymerase chain reaction(MSP)technique.Method The tissue specimens from 32 cases of colon cancer(observation group),and 12 cases of normal colon tissues(control group)were examined,the methylation of CDH13 gene promoter was detected by MSP.Result The methylation of CDH13 gene promoter was detected in 19 cases(59.4％,19/32)in observation group,1 case(8.3 ％,1 / 12)in control group,there was statistical significance between two groups(P =0.002).Conclusion Frequency of the methylation of CDH13 gene promoter is apparently higher in colon cancer tissues than that in normal colon tissues,it reveals that CDH13 gene promoter may contribute significantly to the development of colon cancer.

Objective: To observe the expression of osteopontin (OPN) in the giant cell tumor of bone (GCTB) and to discuss its clinical significance. Methods: OPN expression was examined in 77 GCTB samples by En Vision™ two-step immunohistochemical method. And the expression was compared between patients with different clinical and pathological data; the implied clinical relevance was also analyzed. Results: The positive expression rate of OPN in the GCTB was 76.6%; only weak expression was noted in the normal bone tissues. The expression in the invasive GCTB was significantly higher than that in the non-invasive ones(95.5% vs 69.1%, P=0.013). The expression rate of OPN increased with the increase of Campanacci stages of GCTB, and significant difference was found between different stages(P=O.019). The recurrence status, gender, age, surgery types, duration of illness or site of tumor were not associated with the positive rate of OPN. Conclusion: OPN is highly expressed in GCTB tissues, and the expression is associated with the invasiveness and the Campanacci stages of GCTB.

OBJECTIVETo investigate the correlation between the pathogeneses of diarrhea-pre- dominant irritable bowel syndrome (D-IBS) complicated functional dyspepsia (FD) patients of Gan-stagnation Pi-deficiency Syndrome (GSPDS) and symptoms, psychological states, and gastrointestinal hormones.

METHODSA total of 111 patients with confirmed D-IBS complicated FD of GSPDS were recruited as the treated group by using Rome III standard and Chinese medical syndrome standard. And 30 healthy volunteers were recruited as the control group. The general condition, scoring for digestive symptoms, and the distribution of GSPDS subtype of all subjects were recorded by a questionnaire, and assessed by Symptom Checklist (SCL-90; a software for psychological test developed by Beijing Huicheng Adult Cor- poration). Meanwhile, plasma levels of 5-hydroxytryptamine (5-HT), somatostatin (SS), vasoactive intestinal peptide (VIP), endothelin (ET), interleukin 10 (IL-10), and interleukin 12 (IL-12) were measured in all subjects.

RESULTS(1) The subtype of D-IBS complicated FD of GSPDS was dominant in Pi-qi deficiency type (51/111,45.9%),Pi yang deficiency type (34/111,30.6%), and GSPDS. There was no statistical difference in the scoring of digestive symptoms among the 3 subtypes (P >0.05). (2) Compared with the control group, the anxiety factor score and the total score significantly increased in all three subtypes of D-IBS complicated FD of GSPDS, and the depression score of Pi yang deficiency type and Gan-depression type also significantly increased (P <0.05, P <0.01); the depression score of Gan-depression type was significantly higher than that of the Pi-qi deficiency type (P <0.01). Plasma 5-HT levels were obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities, and VIP and IL-10 levels were significantly lower than those in the control group (P <0.05). Plasma VIP levels were also obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities (P <0.01), and SS levels were significantly lower than those in the control group (P <0.05). There was no statistical difference in plasma ET or IL-12 levels in each patient group, when compared with the control group (P >0.05). (3) Compared with the.control group, plasma 5-HT levels significantly increased, plasma VIP and IL-10 levels significantly decreased in ach subtype of D-IBS complicated FD patients of GSPDS (P <0.05, P <0.01), and no significant change of SS, ET, or IL-12 occurred (P >0.05). Besides, plasma 5-HT levels were significantly higher in Gan-depression type than in Pi yang deficiency type, VIP levels were lower in Gan-depression type than in Pi-qi deficiency type (all P <0.05).

CONCLUSIONSGan stagnation and Pi deficiency were dominant in D-IBS complicated FD patients of GSPDS. Psychological abnormalities, increased plasma 5-HT levels, and decreased plasma VIP levels were closely correlated with Gan stagnation subtype, which provided some reference for looking for objective indicators of Chinese medical syndromes in treating D-IBS complicated FD patients of GSPDS.

Methods Symptom checklist 90(SCL-90)was used for investigation. The corresponding interventions were conducted based on the found problems. Results The mental health of the nurses in general hospital emergency department was worse than that of the general population. Each factor score, the total average score and the number of items after intervention had significant difference than that before intervention respectively. The incidence rate of top 10 symptoms was significantly decreased after the intervention than that before. Conclusions Implementation of comprehensive intervention can significantly improve the mental health of the nurses in emergency department of general hospital.

Objective To investigate the effects of hyperbaric oxygenation(HBO)therapy on serum con- centrations of soluble intercellular adhesion molecule-1(slCAM-1),soluble vascular cell adhesion molecule-1(sV- CAM-1),soluble E-selectin(sE-selectin)and matrix metalloproteinase-9(MMP-9)in patients with aeute cerebral infarction and their clinical implications.Methods One hundred and twelve cases of cerehral infarction in the ca- rotid artery system were assigned into two groups.Patients in the routine treatment group(RT group,n=62)were treated with routine clinical treatment regime,whereas those in the HBO group(n=50)were treated with H BO ther- apy in additioo to routine clinical treatment.Thirty age- and sex-matched normal subjects were recruited and served as controls.The serum concentrations of sICAM-1,sVCAM-1,sE-selectin and MMP-9 were measured hy using ELISA method before and 10 days after treatment.The assessment of neurological deficits using National Institutes of Health Stroke Scale(NIHSS)score was conducted before treatment,and at 10 and 30 days after treatment,and the therapeutic efficacy was evaluated.Results The concentrations of sICAM-1,sVCAM-1,sE-selectin and MMP-9 of the patients were significantly higher than those of the control subjects.These parameters were all decreased signifi- cantly after treatment in the two patient groups.Moreover,these parameters were lower in the HBO group than those in the RT group after treatment.The NIHSS scores of HBO group were significantly lower than that of the RT group at the 30th clay post-treatment.The effective rate of HBO group was higher than that of RT group.Conclusion HBO therapy can decrease the serum levels of sICAM-1,sVCAM-1,sE-seleetin and MMP-9,which might be one of the mechanisms of HBO in the treatment of cerebral infarction.

BACKGROUND:Nowadays,the internal fixation materials for the clinical treatment of femoral intertrochanteric fractures are broadly divided into two categories: intramedulary fixation system and extramedulary fixation system.Artificial femoral head replacement can be selected for unstable intertrochanteric fractures.However,the effects of diverse treatments usualy lack of macroscopical evaluation.OBJECTIVE:To investigate and compare the clinical effects of different surgical treatments for femoral intertrochanteric fractures in the elderly.METHODS:168 elderly patients with intertrochanteric fractures,who were treated in the Department of Orthopedics,Beijing Municipal Corps Hospital of Chinese People's Armed Police Forces from June 2005 to June 2010,were enroled in this study.They were treated by screw plate fixation system (dynamic hip screw,dynamic condylar screw),intramedulary fixation system (Gamma 3 nail,expandable intramedulary nail) and artificial femoral head replacement,including 69 males and 99 females,at the age of 75-94 years,averagely 81.4 years.According to Evans type,there were 20 cases of type Ⅰ,43 cases of type Ⅱ,57 cases of type Ⅲ,33 cases of typeⅣ and 15 cases of type Ⅴ.Operative time,blood loss,weight-bearing ambulation time,and hip function were compared and evaluated in patients of each group.RESULTS AND CONCLUSION:After treatment,patients were folowed up for 14-39 months.At 12 months after treatment,Harris score was used to assess hip function in the affected side.Fracture was healed within 12 months.There was no significant difference in excelent and good rate among four groups (P＞0.05).Operative time and blood loss were significantly better in the expandable intramedulary nail group than in the other groups (P＜ 0.05).Weight-bearing ambulation time was significantly better in the artificial femoral head group than in the other groups (P＜ 0.01).Results suggest that according to fracture typing,in combination with osteoporosis in elderly patients,suitable repair method could improve therapeutic effects for femoral intertrochanteric fractures,and reduce postoperative complications.Dynamic hip screw is firstly selected for Evens types Ⅰ and Ⅱ stable intertrochanteric fractures.The intramedulary fixation system can be selected for unstable intertrochanteric fractures as Evans types Ⅲ-Ⅴ.Artificial hip arthroplasty is good for elderly patients with unstable intertrochanteric fractures as wel as severe osteoporosis.

Objective To investigate the relationship between level of serum tumor necrosis factorα (TNF-α) and interleukin-12 (IL-12) and the antitumor effects of cantharidin sodium vitamin B6.Methods Forty advanced non-small cell lung cancer patients aged 30 to 80 were divided into experimental groups [paclitaxel + cisplatin (TP program) and sodium cantharidate vitamin B6] and control group (only TP program).Peripheral blood was drawn in the day of admission and the seventh day,the level of serum TNF-α and IL-12 were detected by method of enzyme-linked immunosorbent assay (ELISA),the results were analyzed.The World Health Organization (WHO) anticancer drugs in acute and subacute toxicity grading criteria were used to grade the chemotherapy side effects.Results The level of serum TNF-α and IL-12 were no significant difference on admission.After chemotherapy,serum TNF-α and IL-12 of experimental group was significantly higher than control group (P ＜ 0.000 and P ＜ 0.037,respectively).The serum TNF-α and IL-12 of experimental group had upward trend after chemotherapy.After 3 months of treatment,the remission rate was 85.7％ in experimental group,significantly higher than 57.8％ in the control group (P ＜ 0.05).White blood cells,and platelets decrease in the experimental group were significantly reduced than the control group (P ＜ 0.001 and P ＜ 0.009,respectively),and there are no significant difference in nausea and vomiting reaction between experimental and control groups.Conclusions The antitumor effects of cantharidin sodium vitamin B6 might be related to the high level of serum TNF-α and IL-12,cantharidin sodium vitamin B6 in combination with chemotherapy in patients can reduce white blood cell and platelet decline after chemotherapy.
