Proteins extracted from two varieties of Chinese roses leaves were separated by two- dimensional polyacrylamide gel electrophoresis (2-DE) with immobilized pH gradient (IPG). Many difference proteins were isolated with molecular weights ranging 10-30 kDa and pI5-6. Three proteins of high levels observed in a gel were excised and identified using peptide mass fingerprinting and MS-MS. A summary of the identified proteins and their putative functions are presented. They are identified as eIF-5A、LEA protein and Hsp17. 5. Functions of these proteins in plant tolerance to high temperature were discussed.

Objective To investigate the etiological factors, clinical features and prognosis of non- traumatic rhabdomyolysis(RML). Methods The medical records of 13 non-traumatic RML patients hospital- ized between 1995-2006 were reviewed. The etiological, clinical, laboratory and therapeutic data were anal- ysed. Results Among 13 patients with non-traumatic RML, multiple factors were responsible for rhabdomyol- ysis in eight patients and single etiologic factor in 5 patients. Different etiological factors were identified, in- cluding 6 with excessive exercise, 3 with hyperpyrexia, 3 with drugs(including illicit drugs, fenofibrate, cy- closporine), 3 complicated with inflammatory myopathy and 2 with limbs compression. Nine patients had myal- gia and muscle weakness, 6 patients had abnormality in nervous system, 4 patients had hyperpyrexia, 3 pa- tients had digestive symptoms. Nine patients were complicated by coagulation disorders and 6 with acute renal failure(ARF). The serum levels of creatine kinase(CK)were decreased to normal within one month in 6 patients, the patient whose rhabdomyolysis was induced by fenofibrate with diabetes and chronic renal failure showed to inadequate decrease within 60 days. Three patients whose problem was induced by inflammatory myopathy, CK levels decreased within 4 months and 6 months in 2 patients, respectively, but CK level was not returned to normal level in one patient during the 80 follow-up days. Three patients died from multiple causes, such as ARF, coagulation disorders,electrolyte and metabolic disturbances. Conclusion Excessive exercise is the most common cause of non-traumatic RML, followed by drugs and inflammatory myopathy. The prognosis is poor in patients with multiple etiological factors and ARF.

Objective To investigate the effect of human cytomegalovirus (HCMV) on proliferation of colony forming unit T-lymphocyte (CFU -TL)and its interference methods. Methods Normal CFU - TL culture was used as blank control. Normal CFU- TL culture system plus inactivated HCMV fluid as inactivated HCMV control. The dilution of 1:10,1:100,1:1000 were added into CFU -TL colonies culture system directly as infected group. Astragalus (AMI) and ganciclovir(GCV) were added into culture system with HCMV dilution of 1:10 as experimental group. By methylcellulose semi-solid culture, different concentrations of HCMV - AD1699 affect CFU-TL and interfered by astragalus AMI, GCV. CFU - TL were surveyed. The effect of HCMV on CFU-TL proliferation was measured by MTT; HCMV-AD169 DNA in CFU-TL was found by PCR. Results 1. Compared with control group, the numbers of CFU -TL in the HCMV infection groups decreased significantly(P

OBJECTIVETo study 3 different strategies of urine drainage following hypospadias urethroplasty, the clinical nursing in their application, and their effects.

METHODSWe retrospectively analyzed the clinical data of 595 cases of hypospadias treated by urethroplasty. After surgery, 133 of the patients underwent urine drainage by suprapubic cystostomy (group A), 202 by urethral stent- tube indwelling (group B), and 260 by early initiative micturition with the urethral stent-tube (group C). All the patients received routine postoperative nursing care required for hypospadias repair.

RESULTSOperations were successfully completed in all the cases. Group C showed a remarkably shorter hospital stay and lower incidence rates of urinary fistula and urethral stricture than groups A and B (P<0.05), but there were no significant differences in the three indexes between A and B (P<0.05).

CONCLUSIONFor urine drainage following hypospadias repair, early initiative micturition with the urethral stent-tube can significantly reduce postoperative complications, decrease difficulties and workload of nursing care, and shorten the hospital stay of the patient.

The purpose of the study is to find the allergic reaction types and characteristics of Chinese medicine injection ( CMI). The authors monitored patients who used Shuxuetong injection, Dengzhan Xixin injection, Shenqi Fuzheng injection, Shenmai injection, Ciwujia injection, Shuxuening injection, Tanreqing injection, Reduning injection, a total of 150,000 cases were monitored. They used a nested case-control design to group the patients and obtained the serum samples from 14 allergic patients and 55 matched patients. They used enzyme-linked immunosorbent assay (ELISA) to detect serum C3, C4, IgE, IgG, MCT-P, and judge the allergic reaction types: Shuxuetong injection hypersensitivity (1 case), can not determine (1 case); Dengzhan Xixin injection hypersensitivity (1 case), hypersensitivity & anaphylactoid reaction (1 case), can not determine (1 case); Shenqi Fuzheng injection hypersensitivity (3 cases), can not determine (1 case); Shenmai injection anaphylactoid reaction (1 case); Ciwujia injection can not determine (1 case), Shuxuening injection can not determine (1 case), Tanreqing injection can not determine (1 case), Reduning injection can not determine (1 case). The results showed that the main type of allergic reaction of CMI was hypersensitivity, the type of allergic reaction was closely related to the varieties of CMI, the hypersensitivity and anaphylactoid reaction might occur in one patient at the same time which used Dengzhan Xixin injection.

Six 89bp primers were designed on the base of the cDNA sequence encoding the human leptin reported on the NCBI. The synthetic gene with 464bp encoding rhLep was obtained by SOE ( splicing by overlap extension) PCR. The expression vector pET22b(+)/rhLep was constructed and transformed into E. coli BL21 (DE3). The rhLep protein was expressed as inclusion bodies with the yield of more than 50% of total bacterial proteins after IPTG induction. The rhLep protein, which has a molecular weight about 16kD, was purified by Ni2+ affinity chromatography column and identified by SDS-PAGE. The MTT Assay shows that rhLep promotes EC304 cells growth at the low concentration of 10ng/mL to 30 ng/mL, and rhLep appears cytotoxic to EC304 cells with the high dose of 50ng/mL to 225ng/mL. The viability of EC304 cells decreases to 1.2% with the concentration of 225ng/mL of rhLep. The massive apoptosis of rhLep on EC304 cells is observed by AO-staining under fluorescent microscope. All these results would lay the foundation for the further study of its biological functions in vitro and in vivo.

Objective To investigate the expression and significance of Caspase-3 and Survivin at different stages of human hemangioma in children.Methods Fifty-five specimens of hemangioma tissue excised in operation and 8 normal skins removed in operation were harvested from People's Hospital of Gansu Province between Jan.2000 and Dec.2005.The pathologic diagnosis was divided into 3 groups according to Mulliken's standard under microscope:proliferated phase group(n=31),degenerated phase group(n=24),and control group(n=8).All these specimens were examined by immunohisto for Caspase-3 and Survivin expression.Results Caspase-3 positive rate in the proliferative phase and involuting phase were 35.5% and 79.2%,respectively.The positive rate in involuting phase was higher than that that in proliferative phase,the difference between the 2 groups was significant(P=0.045 9).A significant difference was not found between the proliferative phase and normal skin tissue(P=0.057 3).Survivin positive rate in the proliferating and involuting phase were 77.4% and 45.8%,respectively.The positive rate in proliferative phase was higher than that in involuting phase,the difference between the 2 groups was significant(P=0.008 5),the difference in involuting phase and normal skin tissue was not significant(P=0.059 3).Conclusions High level of Caspase-3 expression in vascular endothelial cells in involuting phase in contrast to that in proliferative phase,which indicates that Caspase-3 may play a positive role in the apoptosis of vascular endothelial cells.Survivin may inhibit the apoptosis of vascular endothelial cells in proliferative phase due to it's high expression.Caspase-3 and Surivivin involved in the hemangioma in the regulation of apoptosis.J Appl Clin Pediatr,2009,24(1):51-52

Objective To investigate the mechanism and suppression effect of human cytomegalovirus (HCMV) on proliferation of megakaryocyte progenitors(CFU-Mk)in vitro.Methods Colony forming unit-assay was applied to observe the effect of HCMV-AD 169 strain on CFU-Mk of cord blood. The technique of PCR was used to demonstrate the existence of HCMV-AD 169 DNA in the colony cells of cultured CFU-Mk.Results 1.The number of CFU-Mk colonies in HCMV-infected groups decreased significantly compared with that of control group. The CFU-Mk formation was inhibited significantly after HCMV-AD 169 strain infection.The suppression effect showed a dose-dependent fashion: 46.7 % inhibition with 10 -1of HCMV, 29.7 % with 10 -2 and 14.5 % with 10 -3 in the CFU-Mix assay. The peak of CFU-Mk colonies (d16-18) was not significantly different between control group and experimental groups, but the duration of the CFU-Mk colonies in infected groups was significantly shorter than that in control group.2. HCMV-DNA was positively detected in the colony cells of viral infected group by PCR, while negative in control group.Conclusions HCMV-AD 169 strain may inhibit the differentiation and proliferation of CFU-Mk by infecting the hematopoietic progenitors. HCMV may cause the suppression of hematopoiesis by direct infection, which may be the main reason for HCMV infection associated with thrombocytopenia.
