Objective To compare the therapeutic effect of preoperative chemoradiotherapy or postoperative adjutant chemoradiotherapy for locally advanced rectal cancer.Methods The clinical data of 76 patients with locally advanced rectal cancer from 2011 to 2016 in Guizhou Provincial People's Hospital were retrospectively analysed.A total of 30 cases received preoperative chemoradiotherapy (group A),5 of them received concurrent chemoradiotherapy combined with bevacizumab target treatment.The other 46 cases (group B) were given post-operative adjutant chemoradiotherapy.Both group A and group B were treated with intensity-modulated radiation therapy (IMRT).The chemoradiotherapy regime was as follows:the median of target volume dose was 50.4 Gy (45.0-55.8 Gy);the median of chemotherapy sessions was 26 times (24-28 times).Capecitabine tablets (825 mg/m2,twice a day) were also given on the date of chemotherapy.The clinical data and follow-up results of all patients were compared between the two groups.Results The five-year disease free survival rates of group A and group B were 66.7% and 57.7%,respectively;and the five-year overall survival rates of group A and group B were 81.8% and 73.0%,respectively,no statistically significant difference was found between the two groups (P=0.599,0.489).The anus-preserving rates of patients with tumor below peritoneal reflection in group A and group B were 56.52% and 25.00%,there was statistically significant difference (P=0.045).In the group A,86.6 % patients resulted in down-staging,including 3 cases with complete pathologic response.Conclusion Preoperative chemotherapy could down tumor stage and improve rates of anal preservation and local control without increasing possibility of postoperative complications.Preoperative chemotherapy in combination with bevacizumab target treatment may be more effective in lowering tumor stage.

To investigate the possible mechanism of apoptosis induced by indole-3-acetic acid (IAA) combined with horseradish peroxidase in leukemia cell line K562, cell proliferation and apoptosis of K562 cell were examined by MTT assay and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL), respectively; the activity of superoxide dismutase (SOD) and the quantitative change of MDA were measured by biochemical method; changes of free radical were determined by 2, 7-dichlorofluorescin diacetate (DCFH-DA) probe with confocal microscopy. The results showed that of MTT assay and TUNEL indicated that IAA/HRP could significantly inhibit cell proliferation (P < 0.05) and induce apoptosis of K562 cell (P < 0.01), at the same time a positive correlation was found between apoptosis rate and IAA concentration (r = 0.971, P < 0.01). The activity of SOD and the quantitative of MDA increased, accompanied with a rise in IAA concentration. Results detected by DCFH-DA probe indicated that the fluorescence intensity of intracellular free radical increased, as compared with control, and a positive correlation was found. It is concluded that IAA/HRP can inhibit proliferation of K562 cells and induce K562 cell apoptosis, its mechanism may be related with the increase of intracellular free radical due to the effects of IAA/HRP.

OBJECTIVETo study the clinical factors affecting the outcomes of repeated assisted reproductive technology (ART) cycles.
METHODSA retrospective analysis of the clinical data and outcomes was conducted among 160 patients undergoing repeated IVF/ICSI-ET treatment between January 2006 and April 2009.
RESULTSThe patients with successful clinical pregnancy after two ART cycles (group A) had a younger age and shorter duration of infertility, and had more antral follicles (AFC), more eggs and good-quality embryos with more transferred embryos available and higher good-quality embryo rate (P<0.05) than those who failed to have pregnancy after the cycles (group B). In the second cycle, the patients in group A had higher doses of short-acting GnRHa, r-HCG and HMG and at the same time more good eggs and embryos than in the first cycle.
CONCLUSIONSFemale age is one of the most important factors affecting the pregnancy rate after repeated ART cycles. The clinical pregnancy rate can be enhanced by administering short-acting GnRHa, HMG, oral contraceptives and adjusting the dose of Gn as well as changing the culture medium of embryos.

OBJECTIVETo investigate the value of serum estradiol increment and serum estradiol/follicles on the day of hCG administration in predicting the clinical outcomes of in vitro fertilization-embryo transfer (IVF-ET).
METHODSA retrospective analysis of the IVF-ET data was conducted involving 121 patients who received a long gonadotrophin-releasing hormone agonist (GnRHa) protocol. According to the increment of serum estradiol on the day of hCG administration (relative to the level on the day before hCG administration), the patients were divided into 3 groups (A1, A2 and A3) with a increment ratio below 30%, between 30% and 50%, and over 50%, respectively. In addition, according to the ratio of serum estradiol level on hCG day to mature follicle (diameter ≥ 14 mm) number, these patients were divided into three groups (B1, B2 and B3) with the ratio below 250 pg/ml, between 250 and 350 gp/ml, and over 350 pg/ml, respectively. The hormonal characteristics and clinical outcomes of the IVF-ET cycles were analyzed comparatively.
RESULTSBoth the clinical pregnancy rate (71.05%) and embryo implantation rate (52.63%) were significantly higher in group A3 than in groups A1 and A2 (P<0.05). The best clinical pregnancy rate (67.86%) and embryo implantation rate (49.14%) were significantly higher in group B2 than in groups B1 and B3 (P<0.05).
CONCLUSIONThe variation of serum estradiol shows an important impact on the clinical outcomes of IVF-ET in patients receiving long GnRH-a protocol. Favorable outcomes can be expected with a hCG day serum estradiol increment ratio above 50% and E(2)/follicle ratio between 250 and 350 pg/ml.

OBJECTIVES:
To study the effect of glucose metabolism disorders on the short-term prognosis in neonates with asphyxia.
METHODS:
A retrospective analysis was performed on the medical data of the neonates with asphyxia who were admitted to 52 hospitals in Hubei Province of China from January to December, 2018 and had blood glucose data within 12 hours after birth. Their blood glucose data at 1, 2, 6, and 12 hours after birth (with an allowable time error of 0.5 hour) were recorded. According to the presence or absence of brain injury and/or death during hospitalization, the neonates were divided into a poor prognosis group with 693 neonates and a good prognosis group with 779 neonates. The two groups were compared in the incidence of glucose metabolism disorders within 12 hours after birth and short-term prognosis.
RESULTS:
Compared with the good prognosis group, the poor prognosis group had a significantly higher proportion of neonates from secondary hospitals (48.5% vs 42.6%,
CONCLUSIONS
Recurrent hyperglycemia in neonates with asphyxia may suggest poor short-term prognosis, and it is necessary to strengthen the early monitoring and management of the nervous system in such neonates.

OBJECTIVE:
To investigate a family with congenital dysfibrinogenemia, and analyze the risk of hemorrhage and thrombosis and blood transfusion strategies.
METHODS:
Prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) of the proband and her family members were detected by automatic coagulometer, fibrinogen (Fg) activity and antigen were detected by Clauss method and PT algorithm respectively. Meanwhile, thromboelastometry was analyzed for proband and her family members. Then, peripheral blood samples of the proband and her family members were collected, and all exons of FGA, FGB and FGG and their flanks were amplified by PCR and sequenced to search for gene mutations.
RESULTS:
The proband had normal APTT and PT, slightly prolonged TT, reduced level of Fg activity (Clauss method). The Fg of the proband's aunt, son and daughter all decreased to varying degrees. The results of thromboelastogram indicated that Fg function of the proband and her family members (except her son) was basically normal. Gene analysis showed that there were 6233 G/A (p.AαArg35His) heterozygous mutations in exon 2 of FGA gene in the proband, her children and aunt. In addition, 2 polymorphic loci were found in the family, they were FGA gene g.9308A/G (p.AαThr331Ala) and FGB gene g.12628G/A (p.BβArg478Iys) polymorphism, respectively. The proband was injected with 10 units of cryoprecipitate 2 hours before delivery to prevent bleeding, and no obvious bleeding occurred during and after delivery.
CONCLUSION
Heterozygous mutation of 6233G/A (p.AαArg35His) of FGA gene is the biogenetic basis of the disease in this family with congenital dysfibrinogenemia.
