Objective To investigate the influence of forceps delivery or emergency cesarean section on the maternal and infant outcome in pregnant women with abnormal second stage of labor.Methods We retrospectively analyzed the clinical data of 118 parturients with abnormal second stage of labor in the department of obstetrics and gynecology in our hospital from 2013 January to 2015 February.The involved parturients with abnormal second stage of labor received different delivery modes including forceps delivery and emergency cesarean section, and the delivery time and its influence on the maternal and infant outcome were compared.Results The mean delivery time of forceps delivery and emergency cesarean section was (14.8 ± 5.3) and (32.7 ± 12.6) minutes, the difference was significant (P＜0.05).The bleeding probability and the occurrence of severe neonatal asphyxia in the forceps delivery group was obviously lower than that of maternal emergency cesarean section group (P＜0.05).The influence of emergency cesarean section on the newborn severe asphyxia was more serious than forceps delivery (P ＜0.05).There was no statistical difference in the mild asphyxia, facial bruising, scalp hematoma and neonatal pneumonia between the two groups.Conclusion Compared with emergency cesarean section, forceps delivery can protect the safety of mother and child can reduce dystocia risk coefficient for the pregnant women with abnormal second stage of labor.

This study was purposed to investigate the role of post-thaw infused donor cells for predicting engraftment and hematopoietic reconstitution after unrelated cord blood transplantation (UCBT). The retrospective analysis was performed on clinical data of 97 children with malignant or non-malignant diseases received single unit UCBT from August 1999 to April 2010. The impact of pre-freezing and post-thaw cell dose of total nucleated cells (TNC), CD34(+) cells and colony-forming units-granulocyte/macrophage (CFU-GM) on engraftment and hematological recovery after UCBT was analyzed. Unrelated donors were from Guangzhou cord blood bank (GZCBB) entirely. The results indicated that the pre-freezing TNC (/kg) (mean ± SD: 7.65 × 10⁷ ± 4.26 × 10⁷; median: 6.34 × 10⁷), CD34(+)cells (/kg) (mean ± SD: 4.64 × 10(5) ± 4.47 × 10⁵; median: 3.03 × 10⁵) and CFU-GM (/kg) (mean ± SD: 0.79 × 10⁵ ± 1.09 × 10⁵; median: 0.57 × 10⁵) showed a good correlation with their post-thaw counterparts including TNC(/kg) (mean ± SD: 6.98 × 10⁷ ± 4.12 × 10⁷; median: 6.00 × 10⁷), CD34(+)cells (/kg)(Mean ± SD: 6.86 × 10⁵ ± 8.56 × 10⁵; Median: 4.17 × 10⁵), and CFU-GM (/kg) (mean ± SD: 0.52 × 10⁵ ± 0.52 × 10⁵; median: 0.39 × 10⁵) (r = 0.952, p < 0.001; r = 0.794, p < 0.001; r = 0.478, p < 0.001). Either the pre-freezing or post-thaw number of infused CFU-GM was significant higher in patients who achieved engraftment (n = 70) than those who suffered graft failure (n = 22) (p = 0.023 and 0.011, respectively), but no significant difference of TNC and CD34(+) cells dose (pre-freezing or post-thaw) were found between these two groups. Pre-freezing CFU-GM, TNC, CD34(+) cell dose negatively correlated with the time of neutrophil engraftment (r = -0.285, p = 0.018; r = -0.396, p = 0.002; r = -0.373, p = 0.002), as well as the post-thaw number of TNC and CD34(+) cells (r = -0.260, p = 0.031; r = -0.483, p < 0.001), whereas only pre-freezing CD34(+) cells showed a significant correlation with platelet engraftment time (r = -0.352, p = 0.013). It is concluded that the CFU-GM amount is useful for predicting engraftment of UCBT, while pre-freezing hematopoietic cell doses show superior correlation with the speed of engraftment and hematopoietic reconstitution than their post-thaw counterparts in pediatric recipients, suggesting that it is essential to perform hematopoietic potency assay on each cord blood unit prior to listing or release for administration.

OBJECTIVE: To screen multidrug resistance (MDR) related proteins in human gastric cancer using proteomics technique. METHODS: Two-dimensional electrophoresis (2-DE) was used to separate the total proteins of vincristine-resistant human gastric cancer cell line SGC7901/VCR and its counterpart SGC7901. PDQuest software was used to analyze 2-DE images, and the differential expression proteins between the 2 cell lines were identified by both MALDI-TOF-MS and ESI-Q-TOF. The differential expression level of sorcin, one of the identified proteins, was confirmed by western blot analysis. The effect of sorcin on the development of MDR of SGC7901/VCR was determined by antisense oligonucleotides (ASO) technique. RESULTS: Sorcin as a high expression protein in SGC7901/VCR was identified and the suppression of sorcin expression by sorcin ASO could enhance the vincristine chemosensitivity in SGC7901/VCR. CONCLUSION Sorcin overexpression is related to MDR in human gastric cancer cell line SGC7901/VCR.

OBJECTIVETo investigate the incidence and common types of abnormal hemoglobin diseases of the couples at childbearing age by using high performance liquid chromatography (HPLC) in Guangzhou city.

METHODSThe couple of childbearing age in the Birth defect intervention project and Free pre pregnancy health examination were screened from October 2008 to February 2016 in Guangzhou city. The HPLC was used to detect abnormal hemoglobin; The Gap-PCR and reverse dot blot(RDB) were used to detect thalassemia gene deletions.

RESULTSThe detection rate of hemoglobinopathies was 1.14% in the couples of childbearing age in Guangzhou city. 8 kinds of abnormal hemoglobin were detected: Hb E in 102 cases(17 cases with α thalassemia) , Hb Q-Thailand in 20 cases(18 cases with α thalassemia, 2 cases with α and β thalassemia), Hb D-Iran in 4 cases(2 cases with α thalassemia, 1 case with α and β thalassemia), Hb G-Honolulu in 3 cases(1 case with α thalassemia), Hb J-Bangkok in 2 cases(2 cases with α thalassemia), Hb Osu-Christiansborg in 1 case(with α thalassemia), Hb Hasharon in 1 case(with α thalassemia), Hb Koln in 1 case(with α thalassemia).

CONCLUSIONThe incidence of abnormal hemoglobin diseases in Guangzhou area has been found to be more high, 8 kinds of abnormal hemoglobin are found by HPLC, the HPLC is an effective way to screen the couples of childbearing age for β thalassemia and hemoglobinopathies.

OBJECTIVE: To investigate the efficacy of bone marrow mesenchymal stem cells (BMMSC) on children with refractory graft-versus-host disease (GVHD) and to judge the efficacy of BMMSC by dynamically monitoring the changes of cytokines in children with GVHD before and after infusion of BMMSC, so as to provide a theoretical basis for clarifying the mechanism of BMMSC. METHODS: 17 children with refractory aGVHD including 7 of grade II, 6 cases of grade III and 4 cases of grade IV after allo-HSCT were enrolled. All the children with aGVHD, who received routine immunosuppressive therapy, but the state of disease not improved, were treated with immunosuppressive drugs combined with BMMSC infusion. Study endpoints included safety of BMMSC infusion, response to BMMSC, and overall response of aGVHD. The serum levels of IL-2α, IL-6, IL-10, IL-8 and TNF-α in aGVHD patients were measured by chemiluminescence before infusion of BMMSCs and Day 7, Day 14 after infusion of BMMSCs. RESULTS: The cumulative median dose of BMMSCs was 5.5 (3.4-11.1) × 10/kg for average of 3.7 times, and the median time of 16.5 (4-95) days for the first infusion of MSCs. In 17 cases of refractory GVHD, 14 responded to treatment, whereas 3 patients failed. The total effective rate was 82.4% and no adverse reactions occurred. Of the 14 survived cases (82.4%), the median follow-up time was 944 (559-1245) days from the first infusion of MSCs. The levels of TNF-α in children with grade II, III and IV GVHD before treatment were 9.5±4.3 pg/ml, 16.3±10.9 pg/ml and 35.8±21.2 pg/ml respectively. The difference between grade II and IV, III and IV was statistically significant (P<0.05). Compared with the ineffective group of BMMSC infusion, the serum TNF-αlevel in the BMMSCs treatment effective group was 10.8±5.6 pg/ml vs 40.6±14.8 pg/ml (t=-3.901, P<0.05) before treatment. In the effective group of BMMSCs infusion, IL-10 20±17.4 pg/ml of day 14 was significantly higher than that 7.3±3.1 pg/ml before the treatment (t=-2.850, P<0.05), while , the serum levels of IL-2α, IL-6, IL-8, TNF-α were not statistically significantly different (P＞0.05). CONCLUSION The infusion of BMMSC is safe and effective in the treatment of refractory GVHD in children. TNF-αlevel relates with the severity of GVHD. BMMSC may play an anti-GVHD role by up regulating the level of cytokine IL-10 in vivo.
