BackgroundRetinitis pigmentosa (RP) has the genetic and phenotype heterogeneity.To determine the disease-causing gene is a foundation of gene therapy.Objective This study was to localize the pathogenic gene and screen the gene mutation associated with Han Nationality autosomal dominant retinitis pigmentosa (ADRP) in a Chinese family.MethodsTwenty-one families enrolled this study,including 12 patients with ADRP and 9 individuals with normal phenotype.Perimetry,fundus examination,electrooculogram ( EOG ) and electroretinogram (ERG) were performed in 12 patients.Genetic linkage analysis was performed on the subjects in all known genetic loci related to ADRP with a panel of microsatellite markers.Subsequently,the mutation screening of rhodopsin gene was screened by direct DNA sequencing.This study was approved by Ethic Committee of Zhongnan Hospital of Wuhan University.Informed consent was obtained from each subject.ResultsThe fundus appearance of the proband was in accordance with the ADRP,and the EOG and ERG showed undetectable.Contractive visual field also was exhibited in the proband.Linkage analysis showed that the maximum logarithm of the odds(LOD) score reached 3.6671 at marker D3S1292 at recombination fraction θ =0.0.The results of direct DNA sequencing revealed a C→ G transversion mutation at codon 53 in exon 1 of rhodopsin gene,which resulted in a proline to arginine change (Pro53Arg) in 12 patients.However,no similar mutation was found in the unaffected members of this family.ConclusionsThe missence mutation Pro53Arg in rhodopsin gene cosegregate with the RP disease.It is determined to be a pathogenic factor of this ADRP family.

Objective To compare the clinical effects of intramedullary nails and locking compression plate in the treatment of femur shaft fracture.Methods The clinical data and follow-up records of 43 patients with femur shaft fracture treated by intramedullary nails and locking compression plate were retrospectively reviewed.Including 31 males and 12 females with an average age of 40.07 years(25 to73).According to AO classification:5 cases were type A,24 cases were type B,14 cases were type C.26 patients in group A treated by intramedullary nails and 17 patients in group B treated by locking compression plate.Operation time,fracture union time,blood loss and complications were compared between the two groups.The Karlstrom and Olerud result were compared and analyzed.Results All patients were followed up at an average of 15 months(range 5-24) after surgery.According to Karlstrom and Olerud score system,the excellent and good rate of group A was 88.4％,higher than the group B 82.3％.But there was no significant difference between the two groups.In group A:the operation time (113.77 ±20.14)min,the blood loss in the operation (386.74 ± 65.16) ml,clinical bone healing (15.52 ± 1.77) weeks.All these outcomes were better than group B (P ＜ 0.01).One case in group A appeared screw loose,but X-ray showed the nail stable,the bone wasn't displacement.One case in group B appeared broken plate 1 month after operation,and received twice operation,the clinical outcome was good as well.Another 1 case with fracture delayed union in group B,after internal fixation removed,we check the X-ray showed bone union.Conclusion Two methods of treatment femur shaft fracture can all reach the above requirement.Fixation of intramedullary interlocking nail is the preferred surgery than locking compression plate.

Objective To investigate the pathogenesis of gallbladder chaotic dynamics after partial gastrec-tomy. Methods 140 cases operated by partial gastrectomy after 6 months were randomly examined, they in-cluded one group of 40 cases by Billroth type and the other 100 cases by Eiselsberg type. The ultrasonograph was applied to evaluate the function of gallbladder dynamics and radio-immunity method to determine the content of CCK at the time of having no food and 30 minutes after med. Results BV and RV of Eiselsberg group were bigger than Billroth Ⅰ obviously P<0.05. Gallbladder contraction rate displayed not well obvi-ously as too. The plasm level of CCK had no manifested distinctions in empty stomach cases of the 2 groups, but the increasing gradient plasm level of CCK in Billroth Ⅰ exceeded Eiselsberg type. Conclusions The pathogenesis of gallbladder chaotic dynamics after partial gastrectomy was correlated with the alterative type of partial gastrectomy, the reduction of CCK plasm level, the damage of anterior vagal trunk hepatic branches during the operations and so on led to the disorder of gallbladder emptying and induced cholecystolithiasis.

Objective To evaluate the effect of military performance stress on the changes of concentrations in salivary chromogranin A ( CgA) ,β-endorphin (β-EP) and salivary IgA ( sIgA) of submariners.Methods Twenty-nine submarine soldiers were selected, and their saliva samples were collected separately at the end of a long dive trip and nine months after relaxation ashore.In addition,the saliva samples of twenty-eight graduate students were collected as the normal control.The method of ELISA was used to detect the level of salivary CgA,β-EP and sIgA.Results After long-term dive training, the submariners showed significantly decreased CgA,β-EP and sIgA.Conclusion After a long term dive trip, chronic military performance stress is associated with the decline of salivary CgA,β-EP and sIgA, indicating that the function of sympathet-ic adrenal medulla is suppressed.The biological significance of these changes needs to be assessed in the future.

Objective To investigate the significance of salivary cortisol , dehydroepiandrosterone sulfate (DHEA-S) and cortisol/DHEA-S ratio changes for evaluation of military performance stress .Methods Forty submarine soldiers were selected, whose saliva samples were collected separately at the end of long-term dive training and after nine months of relaxation break.In addition, the saliva samples of thirty-four graduate students were collected the moment they finished a three-hour final examination and one week later .The method of ELISA was used to detect the levels of salivary cortisol and DHEA-S and to count their ratio .Results After long-term dive training , the submarine soldiers showed significantly decreased DHEA-S and an increased cortisol/DHEA-S ratio, but the cortisol level did not change very much .In contrast, the final examination stress did not change the level of cortisol , DHEA-S or the cortisol/DHEA-S ratio among these students.Conclusion This is the first study to show that long-term, chronic military performance stress is associated with the salivary DHEA-S and cortisol/DHEA-S ratio changes .The increase in the cortisol/DHEA-S ratio may be used as an important and useful biomarker to evaluate chronic stress .In addition , it is relatively simple and sensitive to detect stress biomarkers by using saliva samples .

Objective To evaluate the effectiveness and safety of recombinant human endostatin combined with concurrent chemoradiotherapy versus concurrent chemoradiotherapy for advanced non small cell lung cancer ( NSCLC) . Methods Electronic databases including the Cochrane library, PubMed, the Chinese biomedical literature database, China national knowledge internet(,EMbase,VIP and Wanfang database system were searched,until August,2013. The inclusion criteria was efficacy and safety studies of randomized controlled clinical studies in which recombinant human endostatin combined with concurrent chemoradiotherapy was compared with concurrent chemoradiotherapy alone for patients with advanced NSCLC. Cochrane handbook 5. 1. 0 was applied in evaluating the quality of included trials and RevMan 5. 1. 0 software was used for data analysis.Results Five studies including 217 cases of advanced NSCLC were included. The results of the meta-analysis exhibited that compared with concurrent chemoradiotherapy alone, recombinant human endostatin combined with concurrent chemoradiotherapy could increase effective rate [OR=2. 62,95%CI(1. 41,4. 86),P=0. 002]. But there were no significant differences in clinical benefit rate [OR=2. 08,95%CI(0. 92,4. 73),P=0. 08],one year survival rate [OR=1. 18,95%CI(0. 53,2. 66),P=0. 68], improvement in quality of life [OR=1. 57,95%CI(0. 40,6. 07),P=0. 52],rate of leucopenia [OR=1. 25,95%CI(0. 72,2. 17), P=0.43],radioactive esophagitis [OR=1. 16,95%CI(0. 42,3. 21),P=0. 77] and radiation pneumonitis [OR=2. 47,95%CI (0. 34,17. 68),P=0. 37]. Conclusion Compared with concurrent chemoradiotherapy alone,recombinant human endostatin combined with concurrent chemoradiotherapy may be more effective for advanced NSCLC,whereas improvement of life quality and toxicities are similar. For the quality restriction and possible publication bias of the included studies,more high quality randomized controlled trials are required to further verify this conclusion.
