Objective:To investigate the differences between emergency surgery and selective surgery treatment of ankle fractures with dislocation .Methods:In the study , 40 patients with ankle fracture and dislocation were treated and followed up from May 2013 to May 2014, and all the data were collected and analyzed .The subjects involved 29 male patients and 11 female patients .The patients were randomly separated into two groups , and the patients in group A were given surgical intervention within 6 hours af-ter injury , while those in group B were initially given close reduction and given selective operation when the soft tissue condition got better .Group A contained 13 male patients and 7 female patients with average age of 37.10;Group B consisted of 15 male and 5 female, with average age of 37.85.Results:The Baird-Jackson score was applied for assessment of the patients ’ outcomes.According to the score , the outcomes were classified into excellent , good, fair, and poor.In group A (emergency group), the outcomes were 13 (65.0%), 4 (20.0%), 3 (15.0%), and 0, respectively.In group B ( selective group), they were 11 (55.0%), 7 (35.0%), 2 (10.0%), and 0, respectively.The numbers of the patients from excellent to poor were 24 (55.0%), 11 (27.5%), 5 (12.5%), and 0, respectively. Conclusion: There is no significant difference in postoperative function between the two groups , however , early surgical intervention can benefit in accomplishing anatomical reduction much easier and shortening the time of hospitalization , which is cost-saving for the patients .

SUMMARY Pregnancy-related pelvic ring disease brings great suffering to pregnant women, including the separation of the pubic symphysis and sacroiliac joint pain.Hormonal changes leading to ligamentous laxity is the main reason for pregnancy-related pelvic ring disease.In normal pregnant cases, and the physiologic widening at the symphysis is about 3-7 mm.When the widening of the symphysis is more than 10 mm, it may lead to symptoms and need active treatment.Currently the diagnosis of the pubic symphysis separation is based on the clinical symptoms and signs.The treatment of acute pubic symphysis separation bases on conservative therapy, includes bed rest and physical therapy.But when the widening of the symphysis is more than 4 cm, the surgery intervention may be a good treatment.If the conservative treatment is not obviously effective, the surgery consists of plate fixation in the pubic symphysis and sac-roiliac screw fixation.Other indications for the surgical intervention include inadequate reduction, recur-rent diastasis, intractable symptoms, and open rupture.

Objective To investigate the affecting factors on auditory and speech performances in preschool children with unilateral cochlear implantation (CI) .Methods The clinical data of the preschool children (n=165) with unilateral cochlear implantation in the Second Xiangya hospital from January 2006 to April 2013 were collected . These children received rehabilitation according to the method recommended by the China Rehabilitation Research Center for Deaf Children ,and the data were analyzed retrospectively .The categories of auditory performance (CAP) and speech intelligibility rating (SIR) were used to assess their auditory and speech performances .The relationships between the performance and gender ,implanted age ,genotype ,inner ear malformation ,history of hearing aid were evaluated .Results Implanted ages and genotypes were associated with the auditory and speech performance of par‐ticipants (P<0 .05) ,while genders ,hearing aid experience ,and inner ear malformations(enlarged vestibular aque‐duct syndrome ,EVAS)were not significant related (P<0 .05) .Children were found to have achieved better CAP and SIR growths when CI was implanted during 1~3 years old and 2~4 years old ,respectively (P<0 .05) .The outcomes of CI recipients with GJB2 mutation were significantly better than those of the GJB2-nonrelated CI recipi‐ents (P<0 .05) .Conclusion This study provides evidence that CIs during first 1~3 years old having better auditory rehabilitation results than those of during 4~6 years old ,and CIs during 2~4 years old obtaining a better speech development in the first 12 months after operation .Deaf children with GJB2 mutation show better auditory and speech performances after CIs than those of the peers without GJB2 mutation .CIs can be effectively performed in deaf children associated with EVAs as in those without EVAS .

Objective To investigate the distribution characteristics of serum hepatitis B virus (HBV) markers of population in hospital and to provide the basis for prevention and control of virus B hepatitis .Methods 11 210 people in hospital who had accepted HBV serological testing were enrolled ,and were divided into >0 -25-year old group(n=3 553) and >25 -50-year old group(n=7 651) according to their ages .Enzyme-linked Immunosorbent Assay(ELISA) and Roche Cobas E601 Automatic Electro-chemiluminescence immunoassay analyzer were employed to detect serum HBV surface antigen (HBsAg ) ,anti-HBV surface anti-body(HBsAb) ,HBV e antigen(HBeAg) ,anti-HBV e antibody(HBeAb) and anti-HBV core antibody(HBcAb) .Results HBsAg positive rates of subjects in > 0 -25-year old group and > 25 -50-year old group were 16 .16% and 21 .19% ,respectively .The overall positive rates of HBsAg and HBsAb and full-negative rate were 19 .59% (2 195/11 204) ,37 .02% (4 148/11 204) and 11 .84% (1 327/11 204) ,respectively .Conclusion Distribution characteristics of HBV markers of population in hospital may pro-vide a reliable basis for taking effective protective and control measures against virus B hepatitis .

Potassium metabolism in young adult men exercising in the heat for six consecutive days and the effect of potassium deficiency in mice and rats induced by low potassium diet during heat exposure were observed. Increased potassium loss in sweat and lower potassium intake resulted in negative potassium balance. Individuals with a negative potassium balance had lower se- rum potassium levels and higher body temperature after exercise. Potassium deficient mice accomplished less work done (2.372 vs 4.253 Kg.M) but exih-ibited a markedly greater rate of heat gain (1.36 vs 0.87℃/Kg.M) as compared to the controls. The survival rate and cellular energy metabolism also decreasedThese observations suggest that prevention from potassium deficiency must be emphasized during prolonged physical activity under hot environments. According to the linear regression equations between potassium intake and balance, it is proposed that the potassium requirements in mild and medium physical activity in the heat are 40 and 60 mEq/day respectively, and the allowance of potassium in the latter may be 70-80 mEq/day.

Objective To evaluate whether the reverse phase protein array (RPPA) method can be used for detecting TORCH infection in pregnant women .Methods The RPPA method was established for detecting TORCH infection .The positive coinci‐dence rates of TORCH infection detected by the RPPA method and ELISA method in 2000 fresh serum samples from pregnant women were compared for evaluating the feasibility of RPPA in TORCH detection .Results The positive coincidence rates of estab‐lished RPPA and ELISA for detecting TORCH infection was 100 .0% ,91 .1% ,97 .2% ,91 .3% and 93 .0% respectively ,indicating that the detection results of various indexes by RPPA and ELISA had better consistency (P>0 .05) ,but the positive detection rates of RPPA for Rubellavirus ,CMV and HSV‐1 ,2 were higher than those of correspondent ELISA method .Conclusion RPPA method for detecting TORCH infection has the advantages of simpleness ,rapidness ,high sensitivity and strong specificity ,is an effective method of auxiliary diagnosis for bearing and rearing better children in clinical ,and is worthy of being promoted and used in the fu‐ture .
