Objective To explore the clinical features, diagnosis, and treatment of non-immunologic hydrops fetalis (NIHF). Methods The clinical data of 10 cases of NIHF in neonatal intensive case unit during January 2011 to December 2016 were analyzed retrospectively. The related literatures were reviewed. Results In 10 cases of NIHF (6 males and 4 females). the gestational age were 32-42 weeks, and the birth weight was 2.25-3.95 kg. Among them, there were 3 cases of infectious diseases (cytomegalovirus, Streptococcus agalactiae, and parvovirus infection, one case each), 2 cases of fetal cardiovascular abnormalities, 2 cases of chromosomal abnormalities, 1 case of abnormal thoracic structures, 1 case of twin transfusion syndrome, and 1 case of etiology unknown of fetal hydrops. The clinical manifestations showed that there were 8 cases with 2 or more areas of edema (or hydrops), and only 2 cases with skin edema. Finally, 6 cases were cured and discharged, 2 cases were discharged by themself, and 2 cases died. Conclusions Prenatal ultrasound is a reliable method for the diagnosis of NIHF. Fetal edema in early pregnancy, especially with congenital malformations, is recommended for termination of pregnancy. After birth, NIHF should be diagnosed promptly so as to avoid or reduce severe complications.

OBJECTIVETo investigate the function of repair gene LIG4 in radiosensitivity enhancement of rectal cancer cells by curcumin.

METHODSHuman rectal cancer cells HT-29 were cultured in normal. LIG4-overexpression HT-29 cells and blank control plasmid HT-29 cells were established by gene transfection. Both kind of HF-29 cells were further randomly divided into curcumin group, radiotherapy group, curcumin plus radiotherapy group (combined group) and control group. The growth inhibition and apoptosis of cells were detected by MTT and Annexin V/PI respectively. Change of tumor volume was observed in nude mouse xenograft model, and the apoptosis of tumor cells was analyzed by TUNEL.

RESULTSRegarding blank control plasmid HT-29 cells, the growth inhibition rate and apoptosis rate in combined group were significantly higher than those in radiotherapy group(all P<0.05); tumor volume of nude mouse in combined group was significantly smaller than that in radiotherapy group, and the apoptotic index in combined group was significantly higher than that in radiotherapy group (all P<0.05). However, regarding LIG4-overexpression HT-29 cells, the growth inhibition rate and apoptosis rate were not significantly different between combined group and radiotherapy group(all P>0.05); the tumor volume of nude mouse and the apoptotic index were also not significantly different between combined group and radiotherapy group (all P>0.05).

CONCLUSIONDown-regulation of LIG4 is an important mechanism of radiosensitivity enhancement of rectal cancer cells by curcumin.

Objective To explore the efficacy and safety of bedside continuous blood purification (CBP) in the treatment of critically ill neonates.Methods Totally ten critically ill neonates were hospitalized in Department of Neonatal Intensive Care Unit (NICU) in Shanghai Children's Hospital from June 2011 to May 2015, and managed with CBP treatment.The indications of CBP therapy were multiple organ dysfunction syndrome (MODS) failed to conventional treatment or combined with acute renal failure (ARF).The model for CBP was continuous veno-venous hemofiltration dialysis (CVVH).The clinical outcomes included blood electrolytes, serum bio markers, urine output, hemodynamic indicators, dose of intravenous epinephrine before treatment, 6, 12, 24, 48 h after treatment and at the end of CBP.Complications of CBP were also observed.Statistical analysis was performed with ANOVA and Dunnett-t test.Results The underlying problems of the ten newborns were septicemia (n=5), severe neonatal asphyxia (n=2), congenital hereditary metabolic disease (n=2) and traumatic asphyxia (n=l).The venous catheter was successfully inserted for all babies and CBP treatment continued for (86.7 ± 25.9) h averagely with obvious effect.Four of the ten cases were cured and discharged, and the rest six refused to treatment and died after due to irreversible injury of the nervous system although they had survived from the oliguric stage of ARF.The complications of CBP included thrombocytopenia (n=3), catheter blockage (n=2), hypotension (n=l).No hypothermia, thrombosis, bleeding or infection occurred.The mean blood pressure and partial pressure of oxygen in arterial blood/fraction of inspiration oxygen (PaO2/ FiO2) of the ten cases 6 h after the beginning of treatment were higher than those before [(46.4 ± 7.5) vs (36.5 ±8.3) mmHg, 1 mmHg=0.133 kPa;(210.0±62.0) vs (93.0±43.0) mmHg;t=2.647 and 6.378, both P ＜ 0.05].At the 12th hour since treatment start, the blood pH value was 7.4 ± 0.2, which was higher than that before treatment (6.9 ± 0.2, t=2.731, P ＜ 0.05), and kept in normal range.At the 24th hour, the serum levels of potassium, urea nitrogen and creatinine dropped to normal range compared to those before treatment [(4.8±2.9) vs (9.6± 3.6) mmol/L;(7.2±2.3) vs (13.6±6.3) mmol/L;(51.0± 12.0) vs (172.0±23.0) μ mol/L;t=4.571, 5.427 and 21.672, all P ＜ 0.05].Urine output increased from zero before the treatment to (0.7±0.3) ml/(kg · h) after 24 h (t=3.284, P ＜ 0.05).The maintaining dose of intravenous epinephrine decreased since 12 h after the beginning of treatment and was ceased at the 48th hour.Conclusion CBP is an effective and feasible treatment for critically ill neonates.

OBJECTIVETo elucidate the mechanism of curcumin in radiotherapy sensitization for colorectal cancer cells.

METHODSColorectal cancer HT-29 cells were cultured and treated with radiation and curcumin. MTT method was used to detect the cell growth inhibition. Then the high-throughput microarray was used to detect the differences in gene expression levels for each test group to identify differentially expressed genes, and each differential gene was validated by Western blotting.

RESULTSCell growth inhibition rates at 48-hour and 72-hour in curcumin combined with radiotherapy group were significantly higher than those in simple radiotherapy group (P<0.05). Expression of 95 genes associated with gene-injury repair was detected by microarray. Compared to simple radiotherapy group, LIG4 and PNKP expression was down-regulated, and XRCC5 and CCNH expression was up-regulated in the curcumin combined with radiotherapy group (all P<0.05). Western blotting revealed LIG4 and PNKP protein expression decreased, and XRCC5 and CCNH protein expression increased in the curcumin combined with radiotherapy group as compared to the simple radiotherapy group (all P<0.05).

CONCLUSIONRadiation sensitization effect of curcumin on colorectal cancer cells HT-29 may be associated with the regulation of genes of CCNH, LIG4, XRCC5, PNKP.

OBJECTIVETo assess the efficacy and safety of modified ligation of the intersphincteric fistula tract for simple transsphincteric perianal fistula.

METHODSSeventy patients with simple transsphincteric perianal fistula between October 2012 and January 2014 in our department were prospectively enrolled. According to the random number table, patients were divided into two groups: modified-LIFT group (37 cases, from the external opening close to the fistula, dissect the external sphincter fistula to the intersphincteric groove by tunneling technique, resect the lateral free fistula) and LIFT group (33 cases). Clinical parametres before and after operation were compared, and results of pelvic electromyogram (EMG) and anorectal manometry three months after operation were analyzed to evaluated anal function.

RESULTSThe operative time, pain score, hospital stay, and healing time were not significantly different between the two groups (all P>0.05). During the median follow-up of 12 months (3-20 months), the healing rate in modified-LIFT group was 83.8% (31/37), which was significantly higher than 60% (20/33) in LIFT group (P=0.029). After operation, 4 patients had persistent unhealed wound, 2 recurred in modified-LIFT group, while 8 patients had persistent unhealed wound, and 5 recurred in LIFT group. No patients developed anal incontinence. By the pelvic EMG and anorectal manometry 3 months after operation, the duration of motor unit potential, occurrence of simple phase, mean resting pressure and maximun squeeze pressure were not significantly different.

CONCLUSIONModified-LIFT procedure for the management of simple transsphincteric perianal fistulas is a simple and effective operation with higher healing rate and similar anal function as LIFT.
