Objective To observe the therapeutic effect of the Zishen Huoxue Jiedu (ZSHXJD) method on patients with chronic renal failure (CRF). Methods 252 cases of CRF were treated by ZSHXJD method. TCM symptom, the serum level of Cr, BUN, ET, ANP, IL-8, ?2-mg, HGB and level of urine protein were detected. Results After the treatment, TCM symptom, the level of Cr, BUN, ET, ANP, IL-8, ?2-mg and urine protein were found markedly lower than that before the treatment (P

0.05). From clinical point of view,it is suggested that the weight can be advantageous to forecasting Cr of children.

BACKGROUND:Potential mechanisms of scar formation and scar prevention strategies have become more important in current medical research. Scar assessment scales have the potential to contribute to better evaluation of scar properties in both research and clinical diagnosis. OBJECTIVE: To summarize the literatures addressing scar prevention and clinical assessment. METHODS: A computer search of CNKI database from 2000 to 2014, PubMed database from 1975 to 2014 and Foreign Medical Journal Ful-Text Service Database from 2000 to 2014 was performed using the keywords of scar, prevention, treat, cicatrix, assessment, measure in Chinese and English to retrieve articles related to scar prevention strategies and scar assessment scales. Totaly 39 articles meeting the inclusive criteria were included in result analysis. RESULTS AND CONCLUSION: During wound healing, the unbalance between colagen anabolism and katabolism can lead to the formation of pathological scar. Prevention and treatment of pathological scars should be combined, and early intervention was used in wound healing. General scar assessment scales include Vancouver Scar Scale, Visual Analog Scale, Patient and Observer Scar Assessment Scale, Manchester Scar Assessment Scale, Stony Brook Scar Assessment Scale, al of which have the potential to contribute to better evaluation of scar properties in both research and clinical diagnosis.

BACKGROUND:Anterior cervical discectomy and intervertebral disc replacement have been extensively used in treatment of cervical degenerative disease. Its short-term therapeutic effects are encouraging, but it lacks of long-term and comprehensive evaluation.
OBJECTIVE:To observe the folow-up results of a group of cases of anterior cervical discectomy and Mobi-C intervertebral disc replacement for more than 5 years.
METHODS:A total of 25 cases of cervical spondylosis were treated in the 309 Hospital of Chinese PLA from January to September 2009. 19 of them were folowed up. Al patients received anterior cervical discectomy and Mobi-C intervertebral disc replacement. Twenty-three Mobi-C intervertebral disc prostheses were implanted. The range of motion was measured using lateral X-ray films during extension and flexion. Ectopic ossification was assessed by McAfee method. According to the cervical vertebra MRI images, the degeneration of adjacent segments was determined using Pearce classification. NDI score was used to evaluate the function of cervical spine. Pain improvement was evaluated using visual analogue scale score.
RESULTS AND CONCLUSION: A total of 19 patients were folowed up for 59-65 months, averagely 62 months. No significant difference in range of motion was detected before surgery and during final folow-up (P > 0.05). Ectopic ossification in two cases and the degeneration of adjacent segments in one case were found during final folow-up. No prosthesis loosening or displacement appeared. Visual analogue scale score and NDI score were significantly lower during final folow-up compared with that before surgery (P < 0.05). These results indicate that under the premise of reasonable choice of indications, the therapeutic effect of Mobi-C intervertebral disc replacement for degenerative cervical spondylosis was satisfactory in five-year folow-up. The range of motion was good, and the incidences of ectopic ossification and the degeneration of adjacent segments were low.

From January 2005 to January 2008, 23 cases of fractures and dislocations of cervical spine treated with anterior decompression, reconstruction of bone graft with titanium mesh, and titanium locking plates fixation in Department of Orthopaedics, the 309 Hospital of Chinese PLA were retrospectively analyzed, including 16 males and 7 females, aged 41.9 years (ranging 25 ?65 years). The clinical effect and application value of this treatment was evaluated; the conditions at preoperative, immediate postoperative and follow-up were evaluated by JOA grade, and these radiographs were taken. Lordosis (kyphosis) of the fusion segment with Cobb's angle, and lordosis (kyphosis) of cervical spine with D value were measured to evaluate effect of reconstruction and cervical spine physiological curve. All cases were followed-up for 20.5 months (ranging 1-3 years). Clinical stability was reached in all cases during the follow-up. There were significant differences between preoperative and immediate postoperative, between preoperative and follow-up groups in terms of JOA grade, Cobb's angle and D value (P < 0.05). The JOA grade of immediate postoperative was improved compared with that during follow-up (P < 0.05). The mean improvement rate was 63% at 1 year of follow up. A good curative effect was obtained by using anterior locking plate with titanium mesh systems in treatment of cervical fractures and dislocations and a good effect of restoring and maintaining the lordosis of cervical spine can be also obtained.

Objective: To select anti-HAb18G (hepatoma associated antigen) human Fd fragments with guided selection of L chain of chimeric Fab-HAb18. Methods: The human Fd repertories genes were amplified by RT-PCR from PBMC of hepatoma patients, and cloned into the vector pComb3X with chimeric L chain to construct the human-mouse hybrid Fab phage library. HAblSGE, extracellular region of HAblSG, was used as antigen to screen. The positive clones was obtained by ELISA and FCM with p Ⅲ-fusion Fab antibody. The DNA sequences were analyzed. Results: A human-mouse Fab antibody library were constructed with 2?107 PFU. After 6 rounds panning, 7 positive clones were obtained with ELISA and FCM. And sequences of 2 clones with better affinity were same. The CHI belonged to the IgG2 class as the parent Fd, and the variable region belonged to VH3 family. Conclusions: Through the construction of the HuMFab phage antibody library and chemeric L chain-guided selection, we get the available human Fd fragments for subsequent research.

Objective To investigate the health-related quality of life (HRQoL) and its influencing factors in patients with gastric remnant cancer (GRC).Methods A total of 130 patients received gastrectomy more than 10 years ago because of early gastric cancer.According to the gastric remnant canceration after the surgery,patients were divided into GRC group (80 cases) and gastric remnant group (50 cases).Both the patients of these two groups accepted questionnaires of cancer patients' quality of life questionnaire (QLQ) C30 and gastric cancer specific questionnaire QLQ-STO22,the HRQoL were evaluated.The comparison between two groups with normal distribution of data was aralyzed by t test.Wilcoxon rank sum test was applied for the comparison between two groups with non-normal distribution of data.Optimal scaling regression analysis was used for screening HRQoL related clinical influencing factors.Results All the research objectives finished the questionnaires survey.Compared with health control group,the scores of GRC group were lower,which included quality of life evaluation,physical function,role function,emotional function,cognitive function and social function,and the differences were statistically significant (t =-6.678,-7.111,-10.605,-5.748,-4.765 and-21.170,all P＜0.01).The scores of fatigue,pain,diarrhea,nausea and vomiting,loss of appetite,economic difficulties,dysphagia,abdominal pain,reflux symptoms,diet restricted,anxiety,physical appearance and hair loss were higher,and the differences were significant (t=6.925,4.218,4.728 and Z=-5.236,-7.890,-7.698,-10.058,-3.612,-6.914,-9.711,9.940,-7.987 and-4.966,all P＜0.01).Compared with gastric remnant group,the scores of GRC group were lower,which included quality of life evaluation,physical function,role function,emotional function,cognitive function and social function,and the differences were statistically significant (t=-5.861,-5.821,-7.077,-7.999,-2.808and-5.710,all P＜0.01).However the scores of fatigue,pain,diarrhea,nausea and vomiting,loss of appetite,economic difficulties,dysphagia,diet restricted,anxiety,physical appearance and hair loss were higher,and the differences were significant (t=9.363,6.842 and Z=-2.654,-6.256,-3.266,-4.132,-2.854,-7.996,-4.258 and-2.005,all P＜0.01).Compared with health control group,the score of social function of gastric remnant group was lower and the difference was significant (t =-9.820,P＜ 0.01); the scores of diarrhea,nausea and vomiting,economic difficulties,dysphagia,reflux symptoms,diet restricted,physical appearance and hair loss were higher,the differences were statistical significant (t=3.020 and Z=-1.981,-3.775,-6.505,-6.098,-8.032,-3.369 and-3.147,all P＜0.05) ; the symptom scores of fatigue and pain were lower,the differences were significant (t=-2.890 and-2.439,all P＜0.05).HRQoL of patients was positively correlated with education degree,marital status,family income and the disease course of gastric remnant.Conclusions HRQoL of GRC patients decreased to certain degree.Education degree,marital status,family income and the disease course of gastric remnant were the influential factors of HRQoL in GRC patients.

Objective To investigate the relative percentage of normal cognitive function (NCF),age associated memory impairment (AAMI),mild cognitive impairment (MCI) and Alzheimer's disease (AD) in the elderly,and the correlation between cognitive function and ApoE genotypes.Methods A total of 2666 elderly people aged ≥65 years (2132 males and 534 females)were divided into 3 groups according age:65-74-year age group (925 cases),75-84 year age group (1054 cases) and 85-100-year age group (687 cases).ApoE genotypes were determined in the controls and patients with AAMI and MCI.The degrees of fundus arteriosclerosis were detected in all subjects except for patients with AD.Results There were 867 cases with NCF,860 cases with AAMI and 782 cases with MCI.The incidence of AAMI was higher in 65-74-year age group than in the other two groups (42.0％ vs.31.1,20.96).The incidences of MCI and AD were higher in 85-100-year age group than in the other groups (42.5％,13.3％).The major degrees of fundus arteriosclerosis were Ⅰ+,Ⅰ-Ⅱ°,Ⅱ in subjects with AAMI (34.7％,x2=10.02,P＜0.01) and were Ⅱ °/ Ⅱ + / Ⅲ° in subjects with MCI (34.9 ％,x2 =23.39,P＜0.001).The APOEε4 allele frequency was significantly higher in patients with MCI than in the controls (x2=8.31,P＜0.05).However,no significant differences in APOEε4 allele frequency were found between patients with AAMI and the controls.Conclusions The incidence of AAMI is highest in 65-74-year age group,while the incidences of MCI and AD are highest in 85-100-year age group.Compared to patients with AAMI,the more serious fundus arteriosclerosis and higher allele frequency of APOEε4 appear in patients with MCI.
