1.Roles of the liver regeneration phosphatase-3 and its inhibitors in tumor
Journal of International Oncology 2012;39(6):415-417
Phosphatase of regenerating liver-3 (PRL-3) is a novel small molecule protein-tyrosine-phosphatase,which plays an important role in the oncogenesis and deveopment of tumors.Studies show that PRL-3 regulates neoplasm progress through participating in multiple signal pathways.Its high expression can significantly promote neoplasm metastasis in cancer tissue.However,there is no expression of PRL-3 in most normal tissue.PRL-3 is expected to be a potential tumor maker of diagnosis and a new target for the therapy of cancer.

To investigate whether the Bcl-2 gene family is involved in modulating mechanism of apoptosis and change of cell cycle protein induced by curcumin in acute myeloid leukemia HL-60 cell line and primary acute myelogenous leukemic cells, the Bcl-2 family member Mcl-1, Bax and Bak and cell cycle proteins including P27kipl, P21wafl, cyclin D3 and pRbp- were selected and their expression detected by SABC immuno-histochemical stain method. The attitude of sub-G1 peak in DNA histogram was determined by FCM. The TUNEL positive cell percentage was identified by terminal deoxynucleotidyl transferase (TdT)-mediated Biotin dUNP end labeling technique. It was found that when HL-60 cells were treated with 25 mumol/L curcumin for 24 h, the expression level of Mcl-1 was down-regulated, but that of Bax and Bak up-regulated time-dependently. There was significant difference in the expression level of Mcl-1, Bax and Bak between the curcumin-treated groups and control group (P < 0.05-0.01). At the same time, curcumin had no effect on progress of cell cycle in primaty acute myelogenous leukemia at newly diagnosis, but could increase the peak of Sub-G1 (P < 0.05), and down-regulate the expression of Mcl-1 and up-regulate the expression of Bax and Bak with the difference being statistically significant. The expression of P27kipl, P21wafl and pRbp- were elevated and that of cyclin D3 decreased in the presence of curcumin. These findings suggested that the Bcl-2 gene family indeed participated in the regulatory process of apoptosis induced by curcumin in HL-60 cells and AML cells. Curcumin can induce apoptosis of primary acute myelogenous leukemic cells and disturb cell cycle progression of HL-60 cells. The mechanism appeared to be mediated by perturbing G0/G1 phases checkpoints which associated with up-regulation of P27kipl, P21wafl and pRbp- expression, and down-regulation of cyclin D3.

Objective To explore the advantages and disadvantages between the RapidArc plans and fixed-field IMRT plan (IMRT).Methods Ten cases of cervical cancer,aged 55 (36-70),who were to receive post-operative radiotherapy were selected randomly.Single arc (Arc 1),two arcs (Arc 2),and three arc (Arc 3) RapidArc plans and fixed-field IMRT plan were designed respectively in the Eclipse 8.6 planning system.The designing,treatment time,target area,and dose distribution of organs at risk by these 4 planning techniques were compared.Results The values of average planned treatment time by the Arc 1,Arc 2,and Arc 3 ten cases was 98,155,185,and 46 min,respectively.The values of average treatment time in the Varian IX accelerator were 2.15,3.32,4.48,and 6.95 min,respectively.The average mean doses were (48.99±1.08),(49.40±0.51) ,(49.51±0.62) ,and (48.65±0.92) Gy,respectively.The values of homogeneity index (HI) of target were 1.11±0.07,1.07±0.02,1.06±0.02,and 1.12±0.05,respectively.The values of eonformal index (CI) of target were 0.73±0.13,0.87±0.06,0.87±0.06,and 0.79±0.06,respectively.The doses at rectum,bladder,and small intestine calculated by IMRT plan were the lowest,and the doses at the femoral neck calculated by these 4 plans were similar.Conclusions The RapidArc plan is superior in dose distribution at target,HI,CI,and treatment time to IMRT,but IMRT plan is superior to RapidArc in planned dose calculation time and protection of organs at risk.However,in general,the RapidArc plan is better in clinical application than IMRT plan.

ObjectiveTo compare the therapeutic efficacy between warm needling and Western medication in treating chronic atrophic gastritis.MethodSixty patients were randomized into an observation group and a control group, 30 cases in each group. The observation group was intervened by warm needling, selecting Guanyuan (CV4), Qihai (CV6), Zusanli (ST36), Xuehai (SP10), and Geshu (BL17); The control group was by Western medication, including Omeprazole, Amoxillin, Metronidazole, etc. The clinical efficacies were compared after 8-week treatment. Besides, gastroscopewas ordered at outset and after 8-week treatment to compare the therapeutic efficacies.ResultIn comparing the clinical symptoms, the total effective rate was 93.3% in the observation group versus 70.0% in the control group (P<0.05); the gastroscope scores dropped significantly in both groups after 8-week treatment (P<0.05), and the score of the observation group was significantly lower than that of the control group (P<0.05). ConclusionAcupuncture-moxibustion can significantly improve the clinical symptoms and gastroscopic results in patients with chronic gastritis, and its therapeutic efficacy is superior to that of Western medication.

Objective To investigate the clinical features and gene mutation of a newborn with neonatal-onset ornithine transcarbamylase deficiency (OTCD) and report the multidisciplinary perinatal management of the mother with late-onset OTCD.Methods The clinical features,biochemical data and the treatment of a newborn boy with OTCD and his mother admitted by Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine in April,2013,were collected.The ornithine transcarbamylase (OTC) gene in the family was analyzed.Results Serum ammonium in the male newborn gradually increased to 1 020 μ mol/L at 48 h after birth.His blood amino acids level and urine organic acid level showed a pattern indicative of OTCD [blood arginine (97.43 μ mol/L,reference 1.00-25.00 μ mol/L),citrulline (27.43 μ mol/L,reference 4.00-30.00 μ mol/L),ornithine (161.66 μ mol/L,reference 10.00-120.00 μ mol/L) and methionine (70.45 μ mol/L,reference 10.00-50.00 μ mol/L); urine uracil (67.11 μ mol/mol Crea,reference 0.00-7.00 μ mol/mol Crea) and orotic acid (1 372.66 μ mol/mol Crea,reference 0.00-1.50 μ mol/mol Crea)].DNA studies revealed a c.583G > A (G195R) homozygous mutation of the OTC gene.His mother was heterozygous for OTCD and developed acute hyperammonemia during pregnancy.Her blood showed a normal-leveled arginine (8.44 μ mol/L,reference 1.50-25.00 μ mol/L),a normal-leveled citrulline(8.41 μ mol/L,reference 7.00-35.00 μ mol/L),an elevated glutamate(279.15 μ mol/L,reference 45.00-200.00 μ mol/L).Her urine uracil (51.55 μ mol/mol Crea,reference 0.00-7.00 μ mol/mol Crea) and orotic acid (38.75 μ mol/mol Crea,reference 0.00-1.50 μ mol/mol) were elevated.Successful management of her prenatal and postpartum blood ammonia level was achieved after administration of pharmacologic nitrogen scavengers and protein limitation.DNA studies revealed a c.583G > A (G195R) heterozygous mutation in the newborn's mother and grandmother.Conclusions General management on pregnant OTCD women is effective.Male newborn patients often have a poor prognosis.

Objective To discuss the appropriate timing of providing enteral nutrition through nasojejunal tube for patients with severe craniocerebral injury.Methods 126 cases of patients were divided into 3 groups randomly,providing enteral nutrition through naso-jejunal tube for the first group,the second group and the third group within 12~24 hours,48 hours later and 72 hours later after injury respectively.The nutrition situation of 3 groups was recorded 6 hours later,48 hours later,on the 5th day and the 10th day,including indicators such as total serum protein,blood albumin,serum creatinine,etc and complication cases of diarrhea,hemorrhage of digestive tract,palirrhea,aspiration,inhalation pneumonia and so on within 2 weeks after injury.Results In terms of indicators of albumin,creatinine 48 hours after injury and total protein,albumin and creatinine on the 5th day and 10th day,the first group were better than the second and third group,there were statistic differences between the three groups.Complication comparison within 2 weeks after injury:the difference of palirrhea cases among the three groups was significant,the third group had a higher ratio than the first and second group.And there was no statistic difference in the other indicators like diarrhea,hemorrhage of digestive tract,aspiration and inhalation pneumonia.Conclusions It is high time that patients with simple severe craniocerebral injury are provided with enteral nutrition through naso-jejunal tube within 12 to 24 hours,which can improve patients nutrition situation without the increase of the complications.
