Objective To explore the influence of G4 cyberknife treatment of large hepatocellular car-cinoma on liver function,and to evaluate its treatment safety.Methods Sixty-three large liver cancer patients treated with routine G4 cyberknife treatment were retrospectively analyzed,and then statistical analysis of the difference in liver function before and after treatment was conducted.Results After G4 cyberknife treatment of 1 2 months,the levels of ALT,ALP,TBIL,PA were respectively 23.00 U /L,1 1 1 .00 U /L,1 3.70 μmol/L, (81 .87 ±1 3.94)%.Compared with the levels before treatment [28.00 U /L,32.00 U /L,1 1 .30 μmol/L, (86.07 ±1 4.07)%],there were no signi-ficant differences found (Z =-1 .677,P =0.094;Z =-0.504, P =0.61 4;Z =-1 .945,P =0.053;t =1 .271 ,P =0.21 3).The level of ambumin was (34.84 ±4.75)g/L at 1 2 months after treatment,which decreased and the difference compared with the level before treatment [(37.45 ±4.1 4)g/L]was significant (t =3.357,P =0.002).The Child-Pugh grade was 5.80 ±1 .1 7 respectively at the time points of 1 2 months after treatment,and no significant difference was found compared with the Child-Pugh grade before treatment (5.48 ±0.81 ,t =-1 .668,P =0.1 06).Conclusion G4 cyberknife treatment does not cause liver injury.It is safe and reliable in large liver cancer treatment.So,it is worth widely clinical popularizing.

To explore the epidemiological character of Methicillin-resistant Stapkylococcus aureus (MRSA) by the phenotyping and genotyping motheds and to investgate the source, transmission, and the spread of nosocomial MRSA infection, consequently, reducing the nosocomial infection of MRSA. In this study, 19 MRSA strains were isolated from patients and environment in a hospital in two months. Patterns of resistantce against 16 antimicrobial agents and pulsed-field gel electrophoresis ( PFGE) of these strains were analyzed to find the relationship among those isolates Clustering analysis was made from the patterns. Some isolates with high homology was found in 19 MRSA, 11 of them belong to type A, and 8 of them belong to the same subtype A1. They were endemic in burn ward, oncological ward and ICU. In addition, 4 isolates were clustered into group B, all found in the same ward of burn unit Thus, our results indicated a outbreak of MRSA ( A type) in this hospital and the potential prevalence of MRSA (B type) , which might be mediated by health care stuff. It is essential to enhance the infection control implementation and to utilize the PFGE genotyping system for the real-time surveillance of MRSA.

Objective To explore the value of enhanced T2 star weighted angiography(ESWAN)in the treatment of uterine fibroids with high intensity focus ultrasound(HIFU) by analyzing the changes of ESWAN. Methods Uterine fibroids were detected through pelvic conventional MRI and ESWAN 1 day before and after HIFU operation. Different indexes of ESWAN were measured ,and differences were compared with the paired t-test. Results The preoperative and postoperative values of magnitude were 1624.59 ± 53.07 and 1750.13 ± 39.81, phase values were 0.0012 ± 0.0081 Hz and 0.0025 ± 0.1063 Hz,R2*value were 27.69 ± 1.27 Hz and 24.19 ± 1.20 Hz,and T2*values were 34.66 ± 2.07 ms and 36.46 ± 2.14 ms. After HIFU operation,magnitude value,phase value and T2*value were higher(P=0.04,P=0.91 and P=0.45),and R2*value was lower(P=0.019). Conclusions ESWAN can provide more information about histopathologic changes of uterine fibroids after HIFU.

Objective To investigates the feasibility of diffusion tensor imaging (DTI) and diffusion tensor tracking (DTT) for evaluation of the effect of childbearing history on female pelvic floor muscles. Methods Forty-six healthy females were divided into two groups: nulliparous and primiparous. MR conventional sequences and DTI were acquired. The optimized FA threshold value was obtained by regulating the FA to fiber tracking. The two groups were compared in terms of ADC, FA, VRA and T2-WT. Results (1)The DTT of FA 0.18 got the highest score in fiber tracking . ( 2 ) The ADC of nulliparous subjects and the subjects who had given birth were (1.24 ± 0.11) ×10-3 mm2/s, (1.33 ± 0.11) ×10-3 mm2/s (P = 0.017). There were no statistical differences in FA, VRA and T2-WT between the two groups (P > 0.05). Conclusions The optimized FA threshold of fiber tracking in pelvic floor muscles is 0.18. DTI and DTT may be used to evaluate the effect of childbearing history on female pelvic floor muscles.

Objective To evaluate the value of reconstruction of three-dimentional CT in development dislocation of hip(DDH)in children.Methods Twelve cases of DDH concluded 4 bilateral and 8 unilateral cases.To sum up,16 sick hips were operated and 8 normal hips were also obtained by three-dimensional CT(Hip speed Fi/x,GE Co).Results 3D reconstruction were used to show femoral head,(acetabulum) and relationship of acetabulum and femoral head respectively.The difference between FNA measurement of sick hips and those of normal hips were significant(P

Objective To investigate the clinical epidemiologic features of transient synovitis(TS) of hip in children occurred in Shen-zhen district.Methods The medical files were reviewed and a standard questionnaire was filled according to the conditions of 705 cases such as pathogeny,clinical manifestation,therapy and prognosis.Results Transient synovitis occurred in a sporadic form all the year round.The peak age of patients with TS was 3-7 years old.The ratio of boys to girls was 2.9:1.About 19.3% patients were attacked an upper respiratory tract infection and 11.9% patients attributed the symptoms to trauma or severe activities before 1 week.A varying degree of painful limp and restriction of movement at the hip were found clinically.All of cases were cured by skin traction.The incidence of recurrence was 6.95%.Conclusions Male predominance is found in TS.It is characteristic of sporadic form in the 4 seasons and intently relation to an upper respiratory tract infection and trauma or severe activities.TS is recurrent and the prognosis is good by skin traction.
