Objective To explore the effects of family and telephone follow-up on quality of life of the patients with tota1 hip arthroplasty(THA).Methods One hundred and twelve patients with THA were randomly divided into experiment group and control group with 56 cases in each group.The experiment group was treated with rehabilitative instruction by family and telephone follow-up.The control group was treated with outpatient follow-up after leaving the hospital.The living quality in both groups were compared by the medical outcomes study 36-item short-form health survey(SF-36 QOL)one year after leaving the hospital.Results One-year after leaving the hospital,the total score and demension score of experiment group were better than those of the control group.There was significant difference between the control group and in experiment group(P<0.05).Conclusion Family and telephone follow-up is an effective implementation for THA patients to accomplish physiological functional recovery and promote the quality of life.

Objective To investigate the effect of mindfulness on anxiety and depression of gynecological oncology patients.Methods Using objective methods,80 patients with gynecological oncology were divided to the usual care group and mindfulness training group according to random number table,40 cases in each group.The self -rated anxiety scale and self -rated depression scale were used to compare the effects at three times.Results There were 3 patients lost and 77 patients were analyzed finally.The ANOVA showed that there were significant differences on anxiety and depression scores of SAS (F =4.614,P =0.035) and SDS (F =4.070,P =0.044) between the two groups,and the scores of SAS (F =15.115,P <0.001) and SDS (F =7.034,P =0.002) had interaction effects. Conclusion Mindfulness can adjust the psychology state of gynecological oncology patients and decreased the level of anxiety and depression.

To investigate the value of echocardiography in the diagnosis of total anomalous pulmonary venous connection (TAPVC), 16 patients in our hospital were diagnosed to have TAPVC by echocardiography from year 1994 to 2001. In 11 cases the results of echocardiography were compared to those of surgery. Each patient was examined by using a combination of precordial, suprasternal and subcostal windows to visualize all the pulmonary veins and their drainage sites, common pulmonary venous trunk, and other associated abnormalities. Of the 16 cases, the drainage sites were as follow: supracardiac in 10, via vertical vein in 9, directly to superior vena cava in 1; cardiac in 5, via coronary sinus in 2, directly to right atrium in 3. Diagnoses were correctly made in all the 11 cases as confirmed by surgery. Echocardiography can also assess pulmonary arterial pressure and detect other associated abnormalities. It is concluded that echocardiography is the preferred examination method in the diagnosis of TAPVC before surgery. With careful examination using multiple windows and sections, TAPVC can be accurately diagnosed by echocardiography.

ObjectiveTo study the dose and time effects of X-ray radiation on the expression of Pokemon gene and protein in human lung adenocarcinoma cell line A549.MethodsA549 cells was exposed to different doses of X-ray (2,4,6 and 8 Gy),and the expression of Pokemon mRNA and protein of the cells was detected by using Quantitative real-time PCR and western-blotting at 2,4,8,12,24,and 48 h after irradiation. 3-( 4,5-Dimethylthiazol-2-yl )-2,5-diphenyltetrazoliumbromidewasused to detectthe proliferation of A549 cells at 1,2,3,4,and 5 d after 2 Gy X-ray irradiation.The mock treated A549 cells were used as the control.ResultsThe expression of Pokemon mRNA trended to decrease after irradiated with 4,6 and 8 Gy in the earlier period and increased in the later period with statistical difference at the most time points (t =3.40 -154.76,P =0.000 -0.041 ).The expression of Pokemon protein trended to increase and reached the peak at 8 h after irradiated of 2,4,6 and 8 Gy with statistical difference at the most time points ( t =4.18 - 89.64,P =0.000 - 0.039).Compared with the control,the proliferation of A549 cells was significantly inhibited during 3 to 5 d after irradiation of 2 Gy ( t =2.34 - 18.19,P =0.000 -0.040).ConclusionsX-ray irradiation may increase the expression of Pokemon mRNA and protein in A549 cells,which might be correlated with radiation-resistance of A549 cells.

Objective To study the early and mid-term outcome in terms of left ventricular(LV)geometry and function in patients with transposition of great arteries with intact ventricular septum (TGA/IVS) undergoing arterial switch operation.Methods Twenty patients were followed up and divided into 2 groups according to age:the earlier group and the later group.Age and sexual matched controls were also designed as control group 1 and control group 2.LV posterior wall thickness(PWTd),dimension(LVIDd)and length(L) at end diastolic phase,LV end-diastolic volume (EDV),end-systolic volume (ESV),ejection fraction (EF),mitral valve early (E) and late (A) inflow velocities and E/A,isovolumic relaxation time (IVRT) were obtained by two-dimensional echocardiography,normalized isovolumic relaxation time (IVRTn),wall thickness index (PWTd/LVIDd) and LV geometry index(LVIDd/L) were calculated,and these indexes between groups were compared.Results ①Compared with control group 1,PWTd in earlier group was higher [(0.41 + 0.06)cm vs (0.36 + 0.05)cm,P =0.022],but LVIDd had no significant statistical difference [(2.08 + 0.21)cm vs (2.21 + 0.23)cm,P =0.117],indicating PWTd/ LVIDd differed between groups(0.20 + 0.04 vs 0.16 + 0.01 P =0.001).②No abnormalities were observed in later group.③Compared with different age groups in TGA,EDV,ESV,L,LVIDd,PWTd were significantly higher in later group(P =0.000).There were obvious correlations between EDV,ESV,L,LVIDd and examined age (r =0.90,0.83,0.73,0.90,P =0.000,R2 =0.809,0.694,0.528,0.808) while there were no significant correlation between PWTd and examined age(r =0.56,P =0.000,R2 =0.309).Conclusions Early after operation,LV is undergoing hypertrophy or hyperplasia in TGA/IVS,but will recover in the mid-term period,and the function is normal all the time indicating that the LV myocardium may avoided irreversible pathological changes if operated in time.All in all,LV develops well in mid-term period.

Purpose:To evaluate the physical dose distributions and tolerance in locally recurrent nasopharyngeal carcinoma treated with intensity modulated radiation therapy (IMRT).Methods:From June 1999 to August 2000, 10 patients with locally recurrent nasopharyngeal carcinoma proven by histology, without neck lymphoid node recurrence and distant metastasis, were treated by IMRT. The interval from the time of initial radiotherapy to recurrence ranged from 14—50(median 25) months. The initial radiotherapy in all patients were treated with external radiotherapy alone to a median dose of 69Gy/35fractions/52days. IMRT method was performed by means of the MIMiC collimator and inverse treatment planning system (NOMOS company, USA). The prescribed dose of re radiotherapy to target volume was 57Gy/19fractions/4weeks.Results:All patients, except for some patients with mild weight loss and reaction in the oral cavity during radiotherapy, tolerated this IMRT well. IMRT achieved the better immediate responses in 10 patients with complete response in 6 cases and partial response in 4 cases. Recurrence was found in two patients, lung distant metastasis in one patient. The median survival in the 10 patients was 14 months. The median planning target volume (PTV) was 95.8(60—134) cm 3. The dose distributions in the PTV were as follows: median average dose 59.65?2.47Gy, median homogeneity index (HI): 1.18(?0.06); median dose to 95% PTV ≥ 53.2 (?1.36)Gy. The median dose to the organs at risk (OAR) were as follows: spinal cord 9.46?5.23Gy; brain stem 20.24?3.55Gy; left parotid gland 18.53?5.30Gy, right parotid gland 19.68?6.21Gy; left lens 2.11?0.65Gy, right lens 2.94?0.57Gy;Chiasm12.34Gy; left optical nerve13.14 Gy, right optical nerve17.65 Gy.Conclusions:Better dose distributions treated with IMRT was achieved in the patients with locally recurrent nasopharyngeal carcinoma and the patients tolerated this radiotherapy well.
