Objective To investigate the manifestations of myodystonia for recognizing it.Methods Symptomatic myodystonia,relationship between the age of onset and the affected sites,the main clinical types and sex in 292 consecutive cases of myodystonia by retrospective reviewed.Results Symptomatic myodystonia was found accounting for 21.23% in all cases and its major cause was perinatal stage anoxia.Patients who had had early onset (

[Objective]To analyze the relation of age and sex with the incidence of physical examinees with osteoporosis and low bone mass of vertebras.[Method]Quantitative CT(QCT) was used to examine and analyze the lumbar bone mineral density in 575 physical examinees.The data was analyzed by statistical software SAS 9.0.[Result]Bone mineral density(BMD)decreased with age after 50 years old.The occurrence rates of osteoporosis were 56.34% for females at 50-59 years,87.80% at 60-69 years,97.22% at 70-79 years and 100% at 80-89 years,25.44% for males at 50-59 years,50.64% at 60-69 years,66.66% at 70-79 years,and 90.91% at 80-89 years.[Conclusion]The incidence of osteoporosis is positively related with the age.The occurrence rate of osteoporosis increases with increasing age.It is obviously higher in females than in males.

Objective To study the therapeutic effects of low frequency repetitive transcranial magnetic stimulation(rTMS)in cranial dystonia.Methods Twenty cranial dystoina patients were treated with low frequency rTMS.Their motor threshold,cortical silent period(CSP)were evaluated before and after the rTMS and after 1,2,6 months as well as the spares and Toronto Western Spasmodic Torticollis Rating Scale(TWSTRS)to evaluate the effects of rTMS in the treatment of cranial dvstonia.Results The patients scored(23.5±14.0)significantly lower after l and 2 months(17.6 ±14.3,18.5±14.2,t=2.632,2.149.both P<0.05).But there was an increasing tendeney of the score after 2 months.The 2-month efficient rate of low-frequency rTMS Was 60%(12/20),yet the long-term effect of rTMS was still to be studied.There was a very significant improvment of relaxed(46.5%±7.3%vs49.9%±9.2%,t=-3.235.P<0.05)and active threshold(40.2%±5.9%/)5 43.9%±8.8%,t=-2.339,P<0.05),prolongation of CSP((96.1±24.5)ms vs(121.6±27.7)ms,t=-7.223,P=0.000).Conclusion The low frequency rTMS is efficient to relieve the clinical symptoms of cranial dystonia.

[Objective] To evaluate the clinical value of diagnosing osteoporosis with vertebra bone mineral density(BMD) by measurement with quantitative computed tomography (QCT) . [ Method] BMD in of lumbar vertebrae (L<,1～4>)were measured by QCT in 53 healthy middleaged persons or elderly persons (group A) and 68 osteoporosis patients ( groupB) . [Result] BMD in group A declined obviously as age increasing with significant differences (P<0. 01) . In group B,all 68 patients showed osteoporosis according to the diagnostic standard of BMD≤x -2. OSD. Sixty patients showed osteoporosis ifthe diagnostic standard was set to BMD ≤ x -2. 5SD. The BMD values of different age group was lower than the bone quantityblock values. [Conclusion] As a method for diagnosing osteoporosis, QCT has advantages of high sensitation, being precise,being reproducible and is easy for applying. It would be more practical and could decrease mis - diagnosing if the diagnosticstandard was BMD≤x-2.OSD.

ObjectiveTo investigate the efficacy and safety of laparoscope combined with choledochoscopic lithotomy for cholangiolithiasis.MethodsClinical data of 172 patients with cholangiolithiasis treated in the Central People's Hospital of Zhanjiang, Guangdong Province between January 2009 and June 2014 were retrospectively studied. Among the 172 patients, 65 were males and 107 were females with the average age of (44±7) years old. The informed consents of all patients were obtained and the local ethical committee approval had been received. According to the different surgical procedures, the patients were divided into the laparoscope combined with choledochoscopic lithotomy group (minimally invasive group,n=85) and the traditional open lithotomy group (traditional group,n=87). The patients in the minimally invasive group underwent laparoscopic common bile duct exploration + choledochoscopic lithotomy, while the patients in the traditional group underwent open common bileduct exploration + T-tube drainage. The perioperative conditions, postoperative complications and surgical curative effect of the two groups were compared. The data of the two groups were compared usingt test , Chi-square test or Fisher's exact probability test.Results The intraoperative blood loss of the minimally invasive group was (76±20) ml, which was significantly lower than (206±87) ml of the traditional group (t=-13.42,P<0.05). The postoperative evacuation time, defecation time and time of recovery to semi-liquid diet were respectively (2.4±1.0), (4.2±2.1) and (4.5±1.0) d, which were signiifcantly shorter than (3.5±1.5), (5.3±1.4) and (4.9±1.5) d of the traditional group (t=-5.645,-4.051,-2.053;P<0.05). The postoperative length of hospital stay of the minimally invasive group was (7.3±2.5) d, which was signiifcantly shorter than (9.5±2.7) d of the traditional group (t=-5.542,P<0.05). The incidence of incision fat liquefaction or poor healing of the minimally invasive group was 1% (1/85), which was significantly lower than 8% (7/87) of the traditional group (χ2=4.575,P<0.05). The cure rate of the minimally invasive group and the traditional group was both 91% and no signiifcant difference was observed (χ2=0.002,P>0.05). ConclusionsLaparoscope combined with choledochoscopic lithotomy for cholangiolithiasis has the same efifcacy with open lithotomy and has the advantages of high safety, quick postoperative recovery and short length of hospital stay.
