Chinese Journal of Applied Clinical Pediatrics 2014;29(17):1287-1290
Henoch-Sch(o)nlein purpura(HSP) is one of the most common vasculitides in children with many manifestations including skin purpura,arthritis,abdominal pain and renal involvement.The renal involvement(Henoch-Sch(o)nlein purpura nephritis,HSPN) is the principal cause of morbidity and major risk factor for prognosis in HSP.The paper reviewed the updated treatment strategy for HSPN.Accordingly,steroids,cyclophosphamide,mycophenolate mofetil,mizoribine,cyclosporine,triptolide,angiotensin converting enzyme inhibitors (ACEI) / angiotensin receptor blockers(ARB),plasma apheresis and tonsillectomy are possible indicator for the further therapy of HSPN.Furthermore,prospective randomized controlled treatment studies on children with severe HSPN would be needed.
2.Review on Stem Cells Used on Heart Regeneration
Journal of Zhejiang Chinese Medical University 2013;(11):1360-1362
[Objective] This article mainly discussed the potential of myocardial cellregeneration and the possible mechanisms involved. [Method] To study the mechanism of cardiac regeneration ability HSCs, this review studyed the relationship of the differentiation of cardiac stem cells, hematopoietic stem cells, myocardial cells and myocardial regeneration and the possible mechanisms involved. [Result] Self-renewing, differentiation both in vitro and in vivo of the c-kit positive CSCs had been seen. No matter in physiological condition or after damage, the c-kit positive CSCs had clonality and the potential of multi-directional differentiation. Hematopoietic stem cells can generate cardiomyocytes and coronary blood vessels for human celltherapy. The ability of dedifferentiation cells to maintain and improve the ventricular function of a damaged heart is very limited. [Conclusion] CSCs and HSCs play an important role in reversing chronic ischemic and non-ischemic heart failure.

Aim: A new derivative LC-MS method was developed for the simultaneous determination of zofenopril and its active metabolite zofenoprilat to investigate the pharmacokinetic characteristics of zofenopril and zofenopri-lat in healthy Chinese volunteers after single and multiple oral doses of zofenopril calcium tablets. Methods: Ten Chinese healthy volunteers were given three single oral doses of 15,30, and 60 mg, respectively, and consecutively the multiple doses of 30 mg. The concentration and pharmacokinetic parameters of both the parent drug and the active metabolite were simultaneously determined by derivative LC-MS method using p-bromophenacyl bromide (p-BPB) as the derivative reagent. Results: After the single oral administrations of 15, 30, and 60 mg of zofeno-pril calcium, there was no significant difference in the t_(1/2) of both zofenopril and zofenoprilat among the three do-ses. The values of AUC_(0-24h) and c_(max) for both zofenopril and zofenoprilat showed the good linearities to the dosage over the dose range from 15 mg to 60 mg. There were no significant differences in AUC_(0-24h) and c_(max) for both com-pounds between female and male volunteers. After multiple oral administration( 30 mg once daily for 6 days ), the average steady state plasma concentration( c_(av)) for zofenopril was (5. 07 ±1. 06) ng/mL with the degree of fluctu-ation (DF) of 14. 26 ± 2. 94. The c_(av) for zofenoprilat was (6. 28 ± 1. 87) ng/mL with the DF of 11. 61 ±4. 68. The accumulation index values for zofenopril and zofenoprilat were 0. 94 ± 0. 31 and 0. 83±0. 13, respec-tively. Conclusion: Both zofenopril and zofenoprilat were demonstrated of linear kinetics after single administra-tion and showed no accumulation after multiple administration of the test zofenopril calcium tablets. There was significant difference in the pharmacokinetic characteristics for zofenopril calcium between healthy Chinese and European volunteers.

Objective To evaluate the effect and safety of anticoagulant citrate dextrose solution A (ACD-A ) in continuous blood purification (CBP) for patients at high risk of bleeding with ARF. Methods Twelve patients at high risk of bleeding, treated with continuous venovenous hemofiltration(CVVH), were divided into regional citrate anticoagulant (RCA) group and control group. In the former, ACD-A solution was delivered, pre-filter , with the rate adjusted to maintain a postfilter ionized calcium (iCa2+) level between 0.30-0.40 mmol/L. Before the extracorporeal blood returned to the patient, 10% calcium gluconate was infused to maintain a systemic iCa2+ level between 0.90-1.20 mmol/L. In control group, CVVH were performed either with low dose of heparin LMW sodium (1700-2500 IU/12 h-24 h)or without anticoagulant. The life span of each hemofilter was recorded. In RCA group, prothrombin time (PT), activated partial thromboplastin time (APTT) , acid-base changes, serum sodium and iCa2+ were monitored pre- and during CVVH. Result In the whole duration 1192.5 hours of CVVH in RCA group and 596 hours in control group, 62 and 42 hemofilters were used, respectively. Filter survival was 65.3% at 24 h and 24.5% at 48 h in RCA group,while 14.5% and 0 in control group. The mean life span of filter in RCA group was significantly longer than that in control group[(29.4?21.0) (1.5-71.5)h vs( 14.2?8.2) (4.5-40)h, P

Background Primary open angle glaucoma (POAG) is a major blindness-causing disease,characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork lining the aqueous outflow pathway modulates the aqueous outflow facility. To study the biological characteristics of the trabecular meshwork cells has important significance. Objective This study was to culture the trabecular cells from primary open-angle glaucomatous eye (POAG) and study the biologic characteristics of passaged cells. Methods The deep scleral tissue with trabecular meshwork was obtained during the trabeculectomy from 8 eyes with POAG. The trabecular cells were primarily cultured and passaged in vitro. The generation 3 cells were identified by immunochemistry with the laminin (LM), fibronectin (FN) and neuron specific endolase (NSE)monoclonal antibodies. The ultrastructure was examined to observe the biological characteristics of the cells under the transmission electronic microscope. The experimental results were compared among POAG group, normal control group and blank control group. Results The primarily cultured POAG trabecular cells migrated from the edge of tissue mass about 10 days. The cells of generation 3 presented the logarithmic phase in the first 4 days and fused in the 7th day. FN,LM and NSE were positively expressed in the generated cells in POAG group and normal control group rather than blank control group. The MOD values of the generation 3 cells for FN in POAG group and normal control group were 0. 35 ± 0.06 and 0. 26 ± 0. 01, and those for LM were 0. 34 ± 0. 03 and 0. 25 ± 0. 02 respectively, showing statistically significant difference between these two groups ( FN: t = 14. 446, P<0.001; LM: t = 9. 346, P<0. 001 ). The microvilli, cytolysosome and phagocytic vesicle were obviously decreased in the trabcular cells of POAG group compared with normal control group under the transmission electron microscope. Conclusion The trabecular meshwork cells from POAG can be successfully cultured and passaged in vitro. It provides a cytology basis for further glaucoma research.

Background and purpose:Visceral pleural invasion (VPI) and vessel invasion (VI) are poor prognostic factors in patients with non-small cell lung cancer (NSCLC). The primary initial recurrence site may be local recurrence in VPI and distant metastasis in VI. The purpose of this study was to validate the prognostic impact and effect of the initial recurrence site of VPI and VI on survival outcomes for NSCLC.Methods:Two hundred and ninety patients who were diagnosed as having NSCLC and underwent lobectomy between Jan. 2007 and Dec. 2013 were retrospectively analyzed. VPI was identiifed in 51 patients as VPI group, the other 239 patients without VPI as non-VPI group. VI was identiifed in 29 patients as VI group, the other 261 patients without VI as non-VI group. Clinical characteristics, overall survival (OS), disease-free survival (DFS) were compared.Results:There were statistically signiifcant differences between VPI group and non-VPI group in tumor size, lymph node metastasis, TNM stage and initial recurrence site (P<0.05). Furthermore, there were statistically signiifcant differences between VI group and non-VI group in lymph node metastasis and TNM stage (P<0.05). The 1-, 3- and 5-year OS rates in VPI group (88.2%, 56.7% and 52.7%) were lower than those in non-VPI group (95.8%, 83.7% and 74.0%,P<0.001). The 1-, 3- and 5-year OS rates in VI group (79.3%, 56.8% and 48.7%) were lower than those in non-VI group (96.1%, 81.3% and
72.3%,P=0.001). Cox regression showed TNM stage was a significant prognostic factor for DFS, whereas lymph node metastasis and VPI were signiifcant prognostic factors in patients with NSCLC.Conclusion:The primary initial recurrence site in VPI patients is local recurrence. Patients with VPI or VI may need more postoperative therapy because of their poor prognosis.
