Availability of appropriate drugs for children has been a bottleneck both at home and abroad for years.As a result, drugs for adults that are market available emerge a choice of convenience for children's treatment instead.For unique physiological and psychological characteristics of children, these drugs must be dispensed on individual basis before usage to children in question.Such drugs play a key role in children's treatment, and incur many problems on the other hand in their use and practice, such as drug stability, dosage accuracy, potential risks, as well as legitimacy in drug dispensing and use.A safe, reasonable and normalized use of such drugs calls for an orchestrated effort among pharmacists, trade associations and drug regulators as well.

Objective To investigate the difference in influerce of complicated diabetes on the prognosis of kidney transplantation.Methods Analyze the data of 507 times kidney transplantation and clinical tracing.Results Totally 507 patients with kidney function failure had received 539 times kidney transplantation,52 of whom were connected with diabetes[30 male,(51.4?7.1)age;22 female,(51.6?4.9)age],and 16 cases were pre-transplant,36 cases post-transplant.The other 455 cases were non-diabetes[293 male,(38.7?12.3)age;126 female,(43.5?10.1)age].The prevalence of diversified complications in the group with diabetes was all remarkably higher than the other group.There were 9 cases death in the group with diabetes,and 35 deaths in the other group after kidney transplantation;actually the mortality of diabetes group(17.3%,9/52)was 2.45 times as high as the group without diabetes(7.7%,35/455),especially in pre-transplant diabetes group.Another result was that there was no significant difference in the survival period of the dead patients in group with and without diabetes.Conclusion The possibility for the patients who,suffer from kidney function failure with diabetes to get Kidney transplantation postoperative complications is bigger compared with those without diabetes,and the prognosis is poor.To control diabetes more effectively before and after kidney transplantation perhaps can improve the prognosis of them.

In the presence of silver ion, Mn2+ could be electro-oxidized to potassium hypermanganate in phosphoric acid solution, which could effectively react with pyrocatechol in acid solution and luminol in sodium hydroxide solution to produce chemiluminescence. On the basis of this, a novel indirect approach for the detection of Mn2+ was established. The effect of silver ions on the electrochemical oxidation of Mn2+was studied. when 1. 5 ×10-5 mol/L Ag+ and 0. 01 mol/L phosphoric acid solution were used in the process of electrochemical oxidation, the CL intensity could be up to the maximum value after the above solution was electrolyzed for 2 min. The relation of CL intensity and Mn2+concentration in the solutions at different pH and the selectivity were also investigated. when the pyrocatechol was used as luminescent reagent in the acidic medium, the CL intensity was linearly to the Mn2+concentration in the range of 1. 82×10-7-7. 27×10-5 mol/L with excellent selectivity. Common ions had little interferences in the determination of Mn2+. The method was successfully applied to the determination of Mn2+ in surface water and drinking water with satisfactory results.

OBJECTIVETo observe the influence of decreasing conditioning regimen intensity on the engraftment of HLA haplotype peripheral blood stem cell transplantation.

METHODTwelve patients with leukemia, including 4 in complete remission, whose HLAs were full matched with donors, and 8 with refractory leukemia, whose HLAs were mismatched, were transplanted with G-CSF mobilized allogeneic peripheral blood stem cells after conditioned with a regimen consisting of fludarabine (30 mg/m(2) x 6 days), busulfan (4 mg/kg x 2 days) and cyclophosphamide (30 approximately 60 mg/kg x 2 days) (FBC). Donor lymphocytes were infused at day + 30, + 60 and + 90 after transplantation, respectively. Hematopoietic reconstitution was observed. Engraftment was documented by the analysis of short tandem repeats with polymerase chain reaction (STR-PCR).

RESULTPatients in HLA haplotype group received a mean number of 4.87 x 10(8)/kg donor mononuclear cells (MNC), with CD(34)(+) cells of 4.58 x 10(6)/kg and patients in HLA identical group a mean number of 4.85 x 10(8)/kg MNC with CD(34)(+) cells of 4.47 x 10(6)/kg. The mean time of white blood cell count more than 1.0 x 10(9)/L was 14 (10 approximately 18) days in HLA matched patients and 29 (11 approximately 90) days in HLA haplotype group. One three locus mismatched patient failed to engraft, but auto-hematopoiesis was recovered on day + 50. Full donor chimerism was observed in all patients except one with mixed chimera. The mixed chimera was converted into full donor chimera after three times donor lymphocyte infusion. One each died from severe acute GVHD, severe VOD and severe chronic GVHD in HLA haplotype group, and one from chronic GVHD in HLA identical group.

CONCLUSIONPatients survived engraftment was not influenced by decreasing conditioning intensity as in this regimen. Haplotype stem cells could be engrafted durable in recipients by this regimen combined with donor lymphocyte infusion.

OBJECTIVETo explore the effect of quercetin on the invasion, migration, proliferation and cell cycle of glioma U87 cells.

METHODSGlioma U87 cells were treated with 50, 100, or 150 µmol/L quercetin (Q(50), Q(100) and Q(150) groups, respectively) or with DMSO (Q(0) group). Transwell in vitro invasion and migration assays, Click-iT Edu test and flow cytometry were performed to evaluate the effect of quercetin on the invasion, migration, proliferation and cell cycle of U87 cells.

RESULTSAfter 36 h of quercetin treatment, the cells in Q(50), Q(100) and Q(150) groups showed invasive cell percentages (relative to Q(0) group) of 52.08%, 24.63%, and 13.13%, respectively (P<0.05). After quercetin treatment for 12 h, the migrating cell percentages (relative to Q(0) group) in Q(50), Q(100) and Q(150) groups were 49.46%, 26.78%, and 14.56%, respectively (P<0.05). After 24 h of quercetin treatment, the cell proliferation ratios in Q(0), Q(50), Q(100) and Q(150) groups were 25.21%, 18.38%, 16.74% and 15.24%; the cell percentages in phase G0/Gl were 71.14%, 72.71%, 69.29%, and 66.47%, phase S were 25.32%, 22.48%, 21.96%, and 23.32%, and phase G(2)/M were 3.53%, 4.80%, 8.75%, and 10.25% in the 4 groups, respectively, showing a significant difference between groups Q(100), Q(150) and group Q(0) in phase G(2)/M cell percentages (P<0.05).

CONCLUSIONSQuercetin can significantly inhibit the invasion, migration and proliferation of glioma U87 cells by blocking the cell cycle progression.

OBJECTIVE: Our previous study showed that insulin resistance (IR) was related to endometrial hyperplasia as well as endometrial cancer. But the exact impact of IR on fertility-sparing treatment in endometrial hyperplasic disease is unclear. This study investigated how IR affects fertility-sparing treatment in endometrial atypical hyperplasia (EAH) patients. METHODS: The 151 EAH patients received fertility-sparing treatment were retrospectively investigated. All patients received high-dose progestin combined with hysteroscopy. Therapeutic effects were evaluated by hysteroscopy every 3 months during the treatment. RESULTS: The median age was 33.0 years old (range, 21–54 years old). Sixty-one patients (40.4%) were insulin resistant. Three patients were excluded from the analysis because they chose hysterectomy within 3 months after initiation of progestin treatment. The 141 out of 148 (95.3%) patients achieved complete response (CR). No difference was found in cumulative CR rate between those with or without IR (90.2% vs. 95.6%, p=0.320). IR significantly affected therapeutic duration to achieve CR (8.1±0.5 months with IR vs. 6.1±0.4 months without IR, p=0.004). Overweight (body mass index [BMI]≥25 kg/m2) was associated with higher risk of treatment failure (odds ratio=5.61; 95% confidence interval=1.11–28.35; p=0.040) and longer therapeutic duration to achieve CR (7.6±0.5 months vs. 6.3±0.4 months, p=0.019). EAH patients with both IR and overweight (IR+BMI+) had the longest therapeutic time compared with other patients (8.8±0.6 months vs. 5.6±0.7, 6.3±0.4, and 6.4±0.8 months for IR−BMI+, IR−BMI−, and IR+BMI−, respectively, p=0.006). CONCLUSION: IR and overweight were associated with longer therapeutic duration in EAH patients receiving progestin-based fertility-sparing treatment.

Objective: To explore the effect of insulin-like growth factor-Ⅰ (IGF-Ⅰ) receptor on radiosensitivity of HepG2 cells and the underlying mechanism. Methods: HepG2 cells were divided into the following groups: negative control group, siRNA group, irradiation group and combined group. HepG2 cells were transfected with IGF-Ⅰ receptor siRNA combined with irradiation therapy to investigate the effect on cell proliferation by methyl thiazolyl tetrazolium and cell cycle using flow cytometry. Expression of IGF-Ⅰ receptor, proliferating cell nuclear antigen (PCNA), cyclin-dependent kinases 1(CDK1) and Survivin were detected using Western blotting and Q-PCR. Results: The expression of IGF-Ⅰ receptor in HepG2 cells was decreased significantly after siRNA transfection compared with the control group. After the combinational therapy, cell viability was decreased significantly according with control group [(1.02±0.08) vs. (1.08± 0.10) vs. (0.60±0.07)]; In addition, cell cycle was arrested in G2/M[(20.3±0.3)% vs. (22.6±0.4)% vs. (34.7±0.5)%] and CDK1 expression was reduced significantly. The relative expression of Survivin in siRNA group was lower than negative control group, the difference was statistically significant (P<0.05). Conclusion Inhibition of IGF-Ⅰ receptor can enhance the radiosensitivity of HepG2 cells through cell cycle arrest.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.
