OBJECTIVETo observe the efficacy of the treatment of refractory wound by VSD combined with platelet-rich plasma.

METHODSFrom April 2010 to June 2012,15 patients with refractory wound were treated including 11 males and 4 females with an average age of 35.2 years old ranging from 18 to 45 years old. The formation time of wound was from 6 to 24 months, which was unhealed after long-term medication or repeated treatment. The VSD combined with autologous platelet-rich plasma was applied to treat the wound. The wound healing was an indicator and treatment and clinical features were summarized.

RESULTSAll the patients were followed up for 3 to 8 months (means 5 months). The wound of all patients were healed without recurrence.

CONCLUSIONThe curative effect of VSD combined with platelet rich plasma for treatment of refractory wounds is obvious. It could reduce the treatment course and the treatment cost.

Thirty cases of peripheral facial palsy were treated with the comprehensive therapy, and 30 cases of peripheral facial palsy were treated with shallow electro-acupuncture as control. The results showed that the cure rate in treatment group was higher than that in the control group(P＜ 0.05), and no significant difference was found in effective rate between two groups.

Objective:To study the change of immunological response and cell proliferation in breast tissues augmented by polyacrylamide hydrogel injection(PHI).Methods:The expression of CD68,CD25 and PCNA in 20 breast tissues with indurations,12 without indurations after breast augmentation by PHI,and 10 normal breast tissues was examined by immunohistochemistry P-V6000; analysis was also done by H-E staining.Results:Hyperplasia of fibrous tissue and infiltration of inflammatory cells and macrophages were found in the breast and adjacent tissues 3-8 years after PHI.Positive cells of CD68,CD25 and PCNA hardly existed in the normal tissues,but the breast tissues around the polyacrylamide hydrogel had many positive cells of CD68 and PCNA,especially in cases with indurations;there were significant differences between the 3 groups(P

Objective To investigate the relationship between postoperative cognitive dysfunc-tion and plasma cortisol levels in aged patients undergoing total hip replacement surgery. Methods Ninety patients aged 65-75 years old,scheduled for total hip replacement surgery under general anesthesia were enrolled in the present study.Cognitive state was tested by mini-mental state examination (MMSE).The patients were divided into two groups,POCD group and non-POCD group.Perioperative plasma levels of cortisol were determined on 2 d preoperative,2 d postoperative and 7 d postoperative.Results Incidence of POCD after 7 d in aged patients undergoing total hip re-placement surgery was 37.8%.Compared with day 2 d preoperative,plasma cortisol levels in POCD patients significantly increased on 2 d and 7 d post operation (P <0.01 or P <0.05).Compared with non-POCD patients,cortisol levels on the 2 d and 7 d postoperative day significantly increased in POCD patients (P <0.05).Plasma cortisol levels showed a negative correlation with MMSE scores on postoperative 2 d and 7 d(P <0.01).Conclusion Elderly patients have a relatively higher incidence of POCD after hip replacement surgery.POCD may be caused by high plasma cortisol levels in elderly patients following hip replacement surgery under general anesthesia.

Objective To explore the relation between the infection of Helicobacter pylori (H .pylori)and colorectal tumor.Methods From January 2012 to January 2013,the medical data of 152 patients with colorectal tumor were collected.According to the findings of colonoscopy examination, the patients were divided into the colorectal adenoma group (84 cases)and the colorectal carcinoma group (68 cases).A total of 88 healthy individuals were also enrolled as control.The differences of H .pylori infection were compared among the colorectal adenoma group,the colorectal carcinoma group and the healthy control group.The distribution of H .pylori infection in different age,gender and nation was analyzed in colorectal tumor group.According to the location,maximum diameter,number,type of pedicle and pathological type of adenoma,the colorectal adenoma group was divided into subgroups and the condition of H .pylori infection was compared among the subgroups.Chi-square test was used in the statistical analysis.Results The positive rates of H .pylori infection of colorectal adenoma group, colorectal carcinoma group and healthy control group were 70.2% (59/84),72.1 % (49/68)and 53.4%(47/88),respectively,where the former two groups were both higher than that of the healthy control group,and the differences were statistically significant (χ2 =5 .147 and 5 .637,both P <0.05).Regarding the H .pylori infection,there was no difference in age,gender and ethnicity among 152 patients with colorectal tumor (all P > 0.05 ).Among 84 patients with colorectal adenoma,there was no statistical difference in the positive rate of H .pylori infection in different location,maximum diameter,number, type of pedicle and pathological type of adenoma (all P > 0.05).Conclusion H .pylori may have promoting effects on the genesis and development of colorectal tumor.

Glypican-3 (GPC3) is reported as a great promising tumor marker for hepatocellular carcinoma (HCC) diagnosis.Highly sensitive and accurate analysis of serum GPC3 (sGPC3),in combination with or instead of traditional HCC marker alpha-fetoprotein (AFP),is essential for early diagnosis of HCC.Biomaterial-functionalized magnetic particles have been utilized as solid supports with good biological compatibility for sensitive immunoassay.Here,the magnetic nanoparticles (MnPs) and magnetic microparticles (MmPs) with carboxyl groups were further modified with streptavidin,and applied for the development of chemiluminescence enzyme immunoassay (CLEIA).After comparing between MnPs- and MmPs-based CLEIA,MnPs-based CLEIA was proved to be a better method with less assay time,greater sensitivity,better linearity and longer chemiluminescence platform.MnPs-based CLEIA was applied for detection of sGPC3 in normal liver,hepatoeirrhosis,secondary liver cancer and HCC serum samples.The results indicated that sGPC3 was effective in diagnosis of HCC with high performance.

Objective Comparing the effects of steam sterilization on cyclic fatigue of stainless steel files. Meth-ods Fifty instruments of 25# stainless steel K files were randomly divided into 5 groups, which include 10 in each group. Group 1 was the blank control group, group 2 to 5 were subjected to 1, 3, 4, 5 steam sterilization cycles, then the files were tested by a custom-made device to assess cyclic fatigue and the number of cycles of failure (NCF) was calculated. Microstruc-ture of each file’s fracture surface was analyzed by Scanning Electron microscope (SEM). Results NCF in the 5 groups were 4 345.2 ± 384.2,3 937.9 ± 645.4,3 812.9 ± 532.5,3 626.2 ± 380.0,3 625.9 ± 565.6 respectively, and the differences among 5 groups were significantly different(F=2.598, P<0.05). After 4 or 5 times of steam sterilization, cyclic fatigue de-creased if compared with that in control group (P<0.05). Fracture surface in group 1 and group 2 was tough dimple structure and large numbers of regular, deep dimples were distributed on the surface. You could also see micro cavities clearly formed by fracture;Fracture surface in group 4 was dimple structure in brittle intergranular morphology. It is characterized by the presence of thin brittle precipitates, clean and smooth crystal interface, and a great sense of polyhedral stereo. Conclusion After 4 times of steam sterilization, cyclic fatigue strength of 25# stainless steel K files declined, which possessed the poten-tial risk of fracture.
