Heart transplantation(HT) has been an effective method to treat end-stage heart disease, one main factor affecting the long-term survival rate is acute and/or chronic rejection after HT. Trans internal jugular endomyocardial biopsy(EMB) has been the "gold standard" to judge the rejection after HT, but it is also limited. Electrocardiogram ,echocardiogram, immunological monitoring and imaging monitoring can judge the rejection after HT and induce the EMB.

Objective:To establish a method to determine benzoic in ibuprofen suspension. Methods:The determination of ben-zoic was performed on a Kromasil C18 (250 mm × 4. 6 mm, 5 μm) column with the mobile phase consisting of 0. 05 mol·L-1 monopo-tassium phosphate and acetonitrile (72 ∶28). The detection wavelength was 235 nm and the column temperature was 30℃. The injec-tion volume was 10μl. Results:The limit of detection was 3. 57 ng and benzoic had a good linear relationship within the range of 12. 5-200. 0 μg·ml-1(r=0. 999 9). The solution was stable in 24 hours. The average recovery was 98. 42% and RSD was 0. 98% (n=9) . Conclusion:The method is simple, repeatable and accurate, and can be used for the determination of benzoic in ibuprofen sus-pension.

Several comparative studies on anti-implantation and estrogenicities of noret histerone oxime(NETO)and norethisterone(NET) or ethynyl estradiol (EE2)were carried out in order to clarify their relationships. It was observed that NETO was showed much stronger potency than NET, which the anti-implantation, uterotrophic and vaginal cornifi-cation effect were 25, 26, and 21 times, respectively. The ratio of anti-implantation to vaginal cornification of NETO was 14-fold stronger than that of EE2. These results suggest that the increased antiimplantative activity of NETO is related to its stronger estrogenic activity, but other mechanisms contribute to the anti-implantation besides estragenicity.

Objective To investigate the therapeutic effectiveness and safety of mycophenolate mofetil (MMF) in the treatment of chronic allograft dysfunction (CAD).Methods Seventy-eight patients with CAD were administrated with MMF substituting for Aza or CTX with concomitant low-dose CsA. The effectiveness and complications were analyzed. The mean follow-up time after MMF treatment was 9.48 months.Results After treatment with MMF in combination with low doses of CsA and Pred,the serum creatinine concentration (SCr) in 74 CAD patients was significantly decreased and remained stable at the end of follow-up ( P

Objective To discuss the way of treating accelerated rejection. Methods Seven patients of accelerated rejection were treated by efficient anti-rejection treatment. ResultsSix patients of accelerated rejection were reversed by efficient treatment of anti-rejection. One allograft was removed because treatment was invalid. And six patients were still alive, the longest survival one has reached to 3 years. ConclusionThe treatment emphasis of accelerated rejection should be focused on 3 aspects, including early diagnosis, efficient treatment in time, and paying more attention to any possible complications during the process of treatment.

A study of PDCA Cycle in managing hospital medical complaints may introduce such a cycle into the medical complaints control system of a hospital, effectively handling the medical complaints process. Since 2006 when the cycle was introduced into the hospital for medical complaints control, such complaints have been cut back significantly by the end of 2009. Furthermore, such complaints are under control from the start, and prevented from growing into medical disputes, effectively improving quality of care. Such a cycle can effectively avoid medical complaints, enhance medical safety, and build a harmonious doctor-patient relationship.

Sequential monitoring of the levels of serum interleukin-2(IL-2),soluble interleukin-2 receptor(sIL-2R)and interleukin-6(IL-6)were conducted in 60 patients for 2 months after renal transplantation.The results showed that the levels of serum IL-2,sIL-2R and IL-6 were increased significantly several days prior to the clinical diagnosis in the patients with acute rejection,which were much higher than those in CsA-induced nephrotoxicity group.The levels of IL-2,slL-2R and IL-6 in the patients with rejection sensible to methylprednisolone came down to the pre-rejection levels several days after the treatment.It was concluded that sequential monitoring of serum IL-2,sIL-2R and IL-6 of renal allograft recipients are helpful for the early diagnosis and differential diagnosis of acute rejection as well as the evaluation of methylprednisolone in the treatment of antirejection.

Objective:To analyze the effect of MCT/LCT fat emulsions at different doses on the growth and development of prema-ture and low birth weight infants. Methods: Totally 76 cases of preterm or low birth weight infants were divided into the treatment group (40 cases) and the control group (36 cases), both groups were given MCT/LCT fat emulsions, amino acid and glucose injec-tions in 12-24 h after the birth. The initial dose of MCT/LCT fat emulsions in the treatment group was 2. 0 g·kg-1 ·d-1 and the dose was gradually increased to 3. 0 g·kg-1 ·d-1 with 0. 5 g·kg-1 ·d-1 progressive increase. The initial dose of MCT/LCT fat emulsions in the control group was 0. 5 g·kg-1 ·d-1 , and the dose was increased to 3. 0 g·kg-1 ·d-1 with 0. 5 g·kg-1 ·d-1 progressive in-crease. The treatment course was 7 days. The neonatal weight, serum total bilirubin, direct bilirubin, alanine aminotransferase, total cholesterol, triacylglycerol and blood glucose were monitored in the two groups. Results:The born body mass recovery time of the ob-servation group was (4. 38+0. 93) d, which was significantly shorter than that in the control group [(6. 81+1. 90) d]. After the re-covery, the body weight growth rate of the observation group was (30. 41+1. 81) g·kg-1 ·d-1 , which was significantly higher than that of the control group [(18. 21 +2. 08) g·kg-1 ·d-1, P <0. 05]. After the 7-day treatment, the blood biochemical indices showed no statistically significant difference between the two groups (P>0. 05). Conclusion:Early application of MCT/LCT fat emul-sions at high dose is beneficial to the improvement of nutritional status in premature infants.

Objective To explore the mediating effects of college students＇ online social support on the relationship between online self-disclosure and internet altruistic behavior.Methods Using cluster random sampling,the self-disclosure questionnaire for Chinese undergraduates with their internet friend,the online social support scale of adolescence and the internet altruistic behavior scale of undergraduates were applied to 351 college students.Results The score of college students＇ online self-disclosure,online social support and internet altruistic behavior were respectively(2.22±0.45),(2.93±0.59) and (2.04±0.46).The college students＇ online self-disclosure,online social support and internet altruistic behavior were positively correlated with each other (P＜0.01).College students＇ online self-disclosure not only predicted internet altruistic behavior directly,but also predicted internet altruistic behavior indirectly through online social support.The direct effects and indirect effects were 0.200 and 0.265.The ratio of the mediating effect on the total effect was 57％.The fit index of mediation model was x2/df=2.87,RMSEA =0.07,CFI =0.94,TLI =0.93,GFI=0.92,IFI=0.94,NFI=0.91.Conclusion The college students＇ online self-disclosure not only affects the interuet altruistic behavior directly,but also can take the same effect on online social support indirectly.

Objective To study the effects of different dose 6 MV and 10 MV photons for classic conformal radiotherapy on cervical cancer patients with different height and weight,in order to provide guidance for clinical irradiation energy choosing for different patients.Methods Twenty-one recruited patients were divided into obese and non-obese group according to the body mass index (BMI).The 4-field classic conformal radiotherapy plans was designed and applied in both groups and the results were compared.Statistical analysis was carried out on the dosimetric parameters.Results The treatment plan of 10 MV photons could both reduce the maximum and minimum dose (Dmax and Dmin) of the target area PTV and increase the conformal and heterogeneity index (CI and HI),and change the median dose (D50) for non-obese patients,while it could not reduce the mean dose (Dmeen) for two groups.It was more effective in reducing Dmax and increasing HI for obese patients.The plan could also reduce the dose of organs at risk (OAR) near the PTV.Using 10 MV photons plan could more effectively reduce the low isodose volume of the patients and machine hops.Conclusions The 10 MV photons plan has many advantages in classic conformal radiotherapy for obese cervical cancer treatment.
