Objective To explore the clinical effects of enema combined with massage therapy on jaundice in premature infants.Methods Seventy-five premature infants with jaundice were randomly divided into 3 groups,enema combined message therapy group(group A),abdominal massage therapy group(group B),and double-side phototherapy group(group C).All 3 groups were received the same formula fee-ding,intravenous nutrition and identical drug treatment.Group A was given enema with mixed kaiselu and normal saline together with 60 times clockwise abdominal massage once a day for 2 weeks.Group B only received abdominal massage twice per day for 2 weeks.Transcutaneous bilirubin(TB) indexes of all the premature infants in the 3 groups were detected and transformed into total TB concentrations every morning,through version of MINOLTA JM-102 transcutaneous bilirubin radiometer made in Japan.When TB index counted more than 196.58 ?mol/L,group A and B were given single-side phototherapy for 24 hours.Neither enema nor abdominal massage was given to group C,and double-side phototherapy was applied when TB indexes were above 196.58 ?mol/L.Daily TB indexes,duration of jaundice and phototherapy,time of meconium exhaustion,defecation times in each day,incidence of constipation and feeding intolerance were recorded.Results Duration of jaunhospitalized and phototherapy were significantly shortened in group A compared with those of the other groups.In 34 premature infants who were hospital for at least 2 weeks,TB indexes in group C were lower than those in group B on the 9th day.On the 12th day and the 14th day,TB indexes in group A and C were lower than those in group B(Pa

Objective To investigate whether the long non-coding RNA (lncRNA) metastasis associated lung adenocarcinoma transcript 1 (MALAT1) can act as a competitive endogenous RNA (ceRNA) to promote the migration of hepatocellular carcinoma (HCC) cells.Methods Transient transfection of small interfering RNA (siRNA) against MALAT1 was used to knockdown MALAT1 in HepG2 cells.Transwell assays were employed to assess the migration capabilities of HepG2 cells upon MALAT1 knockdown.RNA pull-down assays were performed to validate the direct binding between MALAT1 and miR-126*.Quantitative reverse transcription PCR (qRT-PCR) and Western blotting assays were used to detect the mRNA and protein levels of the miR-126* target genes.The dysregulation and prognostic significance of MALAT1 and miR-126* were analyzed in the public dataset of The Cancer Genome Atlas (TCGA).Results Compared with the control group, MALAT1 knockdown significantly inhibited the migration of HCC cells.MALAT1, with three miR-126* response elements, directly sponged miR-126* in a sequence-specific manner.The mRNA and protein levels of CXCL12, which was the miR-126* target gene, were significantly down-regulated upon MALAT1 knockdown.The TCGA database showed that MALAT1 was significantly up-regulated in HCC and high expression levels of MALAT1 were significantly associated with poor disease-free survival, whereas an opposite pattern of miR-126* was observed.Conclusion This study suggests that MALAT1 directly sponges miR-126* and upregulates the expression of CXCL12, which in turn promotes the migration of HCC cells.

Because of the changed metabolic behaviors of cancer cells, tumor cells uptake a corresponding larger amount of glucose in physiological condition when compared with normal cells. And they were prone to metabolize glucose for generating energy in anaerobic glycolysis ways in order to grow quickly. Anaerobic glycolysis consumes more glucose than aerobic way when the same amount of energy is obtained, which also results in large demand of glucose in tumor cells. This review briefly describes therapy methods related to characteristic mentioned above, and summarizes the research progress of drugs, diagnostic reagents and carriers conjugated with glucose, glucose derivatives or other kinds of sugars for cancer targeting. Furthermore, typically relative research reports from 2012 till now were listed and analyzed.

Objective To characterize the dimerization and the antigenicity of the ORF2 polypep-tide of hepatitis E virus (HEV, genotype 4). Methods HEV ORF2 gene was cloned from the serum of a patient with hepatitis E. The genotype was determined by sequencing. Three ORF2 polypeptides differing in size and other polypeptides with point mutations were produced in E. coli. The recombinant polypeptides were purified and analyzed by SDS-PAGE and Western blot. Results The ORF2 polypeptide containing 459-607 amino acid formed homedimer even in 8 mol/L urea. The truncated polypeptides containing amino acid 472-607 or 459-594 formed monomer only. The mutations at amino acid 562 or 595 disrupted the ho-modimer, whereas the mutations at amino acid 476 or 580 did not. Anti-HEV from hepatitis E patients only reacted with the homodimer form of the polypeptide 459-607 and did not react with monomer or tnmcated pol-ypeptides. Conclusion The amino acid 459-607 of HEV ORF2 is essential for dimerization of the ORF2 polypeptide. Residues at amino acid 562 and 595 are critical for the dimerization. The antigenicity of the polypeptide 459-607 mainly depends on its homodimer form.

Objective To exclude false positivities in detection of IgM antibodies against hepatitis E vires of genotype 4 (HEV-4) using a truncated immunodominant polypeptide of HEV open reading frames (ORF2). Methods The recombinant ORF2 immunodominant polypeptide corresponding to amino acids (AA) 459-607 and a truncated polypeptide corresponding to AA 472-607 were separately applied to coat ELISA plates. Anti-HEV IgM from 35 serum samples with HEV RNA positive, 69 serum samples from healthy individuals and 117 clinically suspicious HEV RNA positive serum samples was detected by an indirect ELISA and was confirmed by western blot in protein level and RT-PCR detecting in RNA level. Results Western blot analysis showed that the sera from HEV patients reacted with the dimmer of peptide 459-607, but they didn't react with the monomer and peptide 472-607. The ELISA showed that all 35 serum HEV RNA positive samples reacted with peptide 459-607 but not with peptide 472-607 and none of the 69 serum samples from healthy individuals reacted with either polypeptide. Among 117 chnically suspicious HEV RNA serum samples, 5 samples reacted simultaneously with both polypeptides. But the difference between 450 nm absorbance (A450) value was less than 0. 5. Western blot analysis demonstrated that all the 5 serum samples were anti-HEV IgM- negative. The 5 serum samples was detected negative by RT-PCR, indicating that the false pesitivities were caused by non-specific absorption. Conclusions ORF2 peptide 459-607 may be used to detect anti-HEV lgM efficiently. The false positivities caused by non-specific absorption can be largely excluded according to the difference between 45Ohm absorbance (A450) value when serum reacts with both polypeptides.

Objective To explore if it is essential to excise ipsilateral adrenal gland in radical nephrectomy.Methods Two hundred and sixty-three patients underwent radical nephrectomy were analyzed retrospectively.The duration of operation,bleeding volumn,complications and survival rates were compared between the adrenalectomy and adrenal preserved groups.The clinical data of the patients with adrenal gland involvement were analyzed as well.Results There were 214 clinical localized(T_(1-2)N_0M_0 )renal cell carcinoma (RCC) patients,26 local advanced RCC(T_(3-4)N_(0-2)M_0 ) patients and 23 metastatic RCC(T_(1-4)N_(0-2)M_1) patients in this study.In the 263 patients,146 cases received ipsilateral adrenal gland excisions,while 117 cases had the ipsilateral adrenal glands preserved.The duration of operation,estimated blood loss and the complications did not differ significantly between these two groups.Only 8 patients had adrenal gland involvement.The mean size of the 8 tumors was 9.7 cm and 5 of them had a diameter ≥8 cm.In the 8 patients,6 had the tumor in the upper pole and 2 had the whole kidney involved.One hundred and twenty-nine clinical stage Ⅰ and Ⅱ patients had ipsilateral adrenal excised,while only 4 (3.1%) had adrenal gland involvement.Seventeen clinical stage Ⅲ and Ⅳ patients had ipsilateral adrenal excised,and 4 (23.5%) had adrenal gland involvements.The clinical stages of these 8 patients were stage Ⅲand Ⅳ.The patients were followed up for 28 months (3-102 months).There was no significant difference of 5-year survival rates between the ipsilateral adrenal gland excised and preserved patients categorized according to pathological stage.Conclusion For patients with renal cancer larger than or equal to 8 cm,localized in upper pole of kidney or with the whole kidney involve and with a clinical stage higher or equal to Ⅲ,it is essential to excise ipsilateral adrenal gland in radical nephrectomy,otherwise the ipsilateral adrenal can be preserved.

Objective To evaluate the value of immunofecal occult blood test (IFOBT) as a prognostic indicator in CKD patients with colorectal impairment.Methods A total of 176CKD patients and 180 healthy adults as control were enrolled.Serum biochemistry was measured at baseline and gastrointestinal bleeding was determined by IFOBT.All the CKD patients were followed up for 4.5 years.Renal replacement therapy or death was defined as end-point event.The Logistic regression analysis was used for risk factors.Kaplan-Meier analysis and COX regression model were used for survival analysis.Results The positive rate of IFOBT in CKD patients was significantly higher than healthy control (17％ vs 5.3％,χ2=13.236,P＜0.01).When comparing with IFOBT negitive patients,IFOBT positive patients were older [(62.030±15.544) years old vs (48.660±19.018)years old,P＜0.01],had higher ESR [(71.800±31.657) mu/h vs (57.210±32.712) mm/h,P＜0.05],C-reactive protein [6.230 (3.000～14.148) mg/L vs 3.000 (3.000～6.833)mg/L,P＜0.05],serum creatinine [419.100 (103.200～546.625) μmol/L vs 175.100 (68.150～462.950) μmol/L,P＜0.05],and had lower hemoglobin level [(97.970±20.590) g/L vs (107.170±27.988) g/L,P＜0.05] and eGFR [11.400 (8.671～53.544) ml·min1·(1.73 m2)1 vs 35.274(10.961～82.145) ml·min-1·(1.73 m2)-1,P＜0.01].There was a negative correlation between IFOBT value and eGFR in CKD patients (r=-0.20,P＜0.01).Positive correlations of IFOBT value with age (r=0.175,P＜0.05) and serum creatinine (r=0.171,P＜0.05) were found.Logistic regression and COX regression analysis showed that IFOBT value,eGFR and ESR were important factors that influenced the prognosis of CKD patients.Kaplan-Meier analysis revealed that IFOBT value ＞100μg/L predicted progression of renal function.Conclusions The prevalence of gastrointestinal bleeding disorder is high in patients with CKD.Value of IFOBT independently predicts decline in renal function of CKD patients.

Objective To verify whether the concomitant performance of modified radical inguinal lymphadenectomy and penectomy may increase complications and compromise oncological effectiveness.Methods From June 2002 to June 2010,a total of 110 simultaneous inguinal lymphadenectomies were performed on 55 patients (mean age 49 years),including 107 modified radical lymphadenectomies,2 radical lymphadenectomies and 1 lymphadenectomy before which the sapheous vein was resected.The records of all patients were reviewed.Results Of 107 simultaneously modified radical inguinal lymphadenectomy,only 1 (0.9％) had wound infection.There were 18 ( 16.8％ ) leg lymphedema and 6 (5.6％) skin flap necrosis,postoperatively.The average number of inguinal lymph nodes dissected was 11 (3 -23 ).Overall 3-year survival was 84％.Conclusions Penile surgery combined with simultaneously modified radical inguinal lymphadenectomy could be feasible,which may have oncological control without increasing the risk of surgical complications.

Objective To report a modified radical inguinal lymphadenectomy the aim of which is to reduce the incidence of the complication of skin necrosis.Methods One hundred and twenty-six modified radical inguinal dissections were performed in 63 patients with penile carcinoma from June 2002 to June 2010.A modified radical inguinal dissection characterized by an S-shaped incision and precisely separating layers using an anatomical mark was performed.The boundaries of dissection were the same as classic radical inguinal lymphadenectomy.The incidences of complications of skin flap necrosis were retrospectively analyzed.Results The follow-up time ranged from 12 to 93 months.A total of 37 complications occurred,including 7 minimal skin necroses (5.6％),3 wound infections (2.4％),19 lymphedemas (15.1％),2 seroma formations (1.6％),5 lymphocele (4.0％),and 1 deep venous thrombosis (0.8％).There were no complications in 106 dissections (84.1％ ),and 20 dissections had one or two minor complications ( 15.9％ ).Conclusions The complication of skin necrosis related to groin dissection in patients with penile carcinoma could be reduced by using this modified inguinal dissection technique,which characterized by an S-shaped incision and precisely separating layers with using an anatomical landmark.

Objective To investigate the techniques of laparoscopic retroperitoneal lymph node dissection(LRPLND)through extraperitoneal approach. Methods Seven non-seminomatous germ cell testicular tumor(NSGCT)patients of clinical stage Ⅰ underwent LRPLND through extraperitoneal approach.The average age was 31(27-39 years old),the average weight was 62 kg(weight 58-72 kg).Pathological examination revealed 2 testis mixed carcinoma(major of embryonal carclnoma and seminoma),2 yolk sac tumor,1 ehoriocarcinoma,2 teratoma with seminoma.Two of them were in right side,and 5 in left.All the chest X-ray,abdominal CT and bone scanning of them were normal before operation.All patients were general anesthetized.Three or 4 trocars were placed,from 2 of them two gasbags were used to expand the retroperitoneal space at volume of 800-900 ml.The retroperitoneal fat was cleared off from the surface of Gerota's fascia to iliac fossa and the plane spance betwwwn anterior rena fascia and posterior peritoneum was separated In the same way the Plane between dorsal renal and the surface of psoas major and quadratus lumborum unto iliae lossa was exposed.Abdominal aorta or vena cava was exposed,then divided and dissected free from surfaee of psoas maior.The conflux of renal vein and testicular vein at the deep face of renal artere(left)was exposed,then testicular vein was ligated and divided it at its end.Fat and lymph tissue between ureter and vessels was dissected to the crotch of abdominal aorta or inferior vena cava.The primary inguinal incision of testectomy was then excided.Normal antegrade ejaculation recovered in 1 month postoperatively. Results The initial 2 operations were converted to open way as the peritoneum were penetrated largely.The other 5 operations were successful.The average operating time was 285 min(245-350 min),intraoperative blood loss was 100-250 ml.Four patients'pathologic results accorded with clinical staging,and 2 positive lymph nodes were found in the other one.The average number of lymph node resected was 25.6 counts(22-31).Follow-up for 3-20 months,chest X-ray and abdominal CT revealed no evidence of recurrence or distant metastasis,and serum tumor markers were in normal range.Normal antegrade ejaculation recovered in 1 month postoperatively. Conclusions The technique through extraperitoneal approach could be applied for LRPLND.It might be an approach for diagnosis and treatment of stage Ⅰ NSGCT.
