Chinese Journal of Rehabilitation Theory and Practice 2002;8(12):755-756
ObjectiveTo study the effect of hyperbaric oxygenation (HBO) treatment on post-stoke depression (PSD) and neurological functional rehabilitation.Methods60 patients with PSD were randomly divided into two groups, treatment group and control group. Patients in the treatment group were given HBO treatment in addition to the regular treatment. Changes of scores of Hamilton depression (HAMD), Chinese stroke scale (CSS), and activity of daily living (ADL) before and after treatment in two groups were observed and evaluated.ResultsAfter 1 month treatment scores of HAMD, CSS, and ADL in the treatment group got obviously better results than before treatment (P<0.01). While scores in the control group had no significant difference(P>0.05).Conclusions It is suggested that HBO may improve the depressive symptom and neurological functional rehabilitation in PSD patients.

The aim of this study was to assess the peri-implant parameters and evaluate the clinical status with the survival of dental implants in body of maxilla after treatments of oral tumor. A follow-up examination included 27 patients who underwent the ablative tumor and (or) reconstructive surgery during a 5-year period. The follow-up protocol included clinical examination, radiological evaluation, and an interview using a standardized questionnaire. The reasons related to implant failure were studied by comparing the amount of failure with the value of marginal bone resorption, probing pocket depth, and plaque index using statistical t-test. The relationship between smoking and implant failure was analyzed statistically by chi-square test. The results showed among the 112 implants observed after implant loading, 29 have failed with the failure rate being 22.14 %. There was no significant correlation between the peri-implant status and the implant failure (P>0.05), however, the association of smoking and implant failure was statistically tested (P<0.05). It was suggested that the association of peri-implant status and implant failure in the maxilla after tumor surgery can't be statistically tested, however smoking was still a mainly significant factor.

Objective A method was established for genotyping of hepatitis B virus (HBV A-D genotype),based on the PCR-restriction fragment length polymorphism (RFLP) created by Hinf Ⅰ,Ear Ⅰ,Apo Ⅰ action on an amplified segment of the S region.Methods Clinical diagnosis research.One hundred and twenty-eight HBV S sequences obtained from GeneBank were analyzed for restriction enzyme sites that would be genotype-specific.Restriction patterns following digestion with restriction enzymes Hif Ⅰ,Ear Ⅰ,Apo Ⅰ were determined to identify A-D HBV genotypes.The method was used to detect the HBV genotype of fifty severe hepatitis patients due to chronic hepatitis B in China.Then the detection results were confirmed by direct sequencing.Results The new genotyping method was established,named simple PCR-RFLP,which could identify HBV genotypes A to D.Genotypes B,C,B/C and A or D could be determined by a single step digestion with Hif Ⅰ.Eight patients of genotype A/B/C classified by single step digestion with Hif Ⅰ were conformed as genotype B variant by further digestion and direct sequencing.Extracted randomly and diluted into different concentration,three specimens were tested for genotype of HBV repeatedly and respectively.The results were all in accord with the originals,and the lowest detection limit of HBV DNA was 7 ~ 9 IU/ml.This was particularly useful in China where genotypes B and C were predominant.Twenty-three of genotype B and ten genotype C patients were classified from these fifty severe hepatitis B patients by a single step digestion with Hif Ⅰ through the simple PCR-RFLP method.The same results were also obtained by direct sequencing of PCR products (Kappa =1.00,P =0.001).The simple PCR-RFLP method was superior to direct sequencing in detecting HBV B/C polyinfection (9 cases and 0 case; x2 =18.00,P =0.001).Conclusions Both the sensitivity and repetitiveness of Simple PCR-RFLP method are satisfactory.It is superior to direct sequencing in detecting HBV B/C polyinfection,and simple,convenient.

Objective To investigate the expression of membrane type 1 matrix metalloproteinase(MT1-MMP) in the esophageal carcinoma tissues and in normal periearcinomatous tissues and its clinical significance. Methods Immunohistochemistry was used to study the expression of MT1-MMP in esophageal carcinoma tissues and normal tissues in distance for 5-7 em from tumor. Results Among 54esophageal carcinoma specimens, the positive expression rate of MT1-MMP was 87.0%, while all of themwere expressed a small quantity in normal esophageal epithelial tissues, the expression in the esophageal carcinoma tissues was significantly higher than those in normal esophageal epithelial tissues (P < 0.01 ).The degree of MT1-MMP expressions was associated with the depth of tumor invasion (P < 0.01 ), the invasion of the lymph nodes(P < 0.01 ) and the relapse and/or metastasis of the tumors for three years after surgery(P <0.01 ), and was also related to differentiation of tumor cells (P < 0.01 ). Conclusions The expression of MT1-MMP in the esophageal carcinoma tissues is well associated with the depth of tumor invasion, the invasion of the lymph nodes, the differentiation of tumor cells and relapse and/or metastasis of the tumors for three years after surgery. MT1-MMP plays an important rote in the invasion and metastasis in the patients with esophageal carcinoma.

Objective To explore the risk factors and seek effective intervention of intracranial hemorrhage in the premature in-fants .Methods Clinical data of the premature infants in our hospital from January 2009 to December 2013 was retrospectively ana-lysed and single factor analysis of 20 relevant factors was done for cases with intracerebral haemorrhage and without intracerebral haemorrhage .Logistic regression analysis were done for some influence factors of intracranial hemorrhage .Results 1 726 cases of premature babies were included in the study ,including 264 cases of intracranial hemorrhage .Logistic regression analysis results shown that the neonatal transport network and integrated active transport models are protective factors of intracranial hemorrhage in the premature infant .We found that basic-level hospital transport was an independent risk factor .Between January 2009 and De-cember 2011 ,142 of 714 premature infants were intracranial hemorrhage ,including 88 cases from 348 patients transported from bas-ic-level hospital ,the incidence of intracranial hemorrhage was 25 .29% ,and compared with the incidence of intracranial hemorrhage (14 .75% ) of our hospital ,the difference was statistically significant (P<0 .05) .From January 2012 ,we established perfect neonatal transport network and implementation of comprehensive active transport model .122 of 1 012 premature infants were intracranial hemorrhage ,including 75 cases of 490 patients from basic-level hospitals .The incidence was statistically significant different com-pared with the incidence of intracranial hemorrhage(9 .00% ) transported from our hospital(P<0 .05) .The incidence of intracranial hemorrhage in the premature infants transported from basic-level hospitals were statistically different before and after neonatal transport network and comprehensive active transport model was established (P<0 .01) .Conclusion It will effectively reduce the incidence of intracranial hemorrhage in the premature infant by establishing the perfect regional neonatal three-level network trans-port system and comprehensive active transport models .
