Objective To analyze the prognostic factors of patients with leukemia treated with single fraction total body irradiation (SFTBI) followed by hernatopoietic stem cell transplantation (HSCT).Methods From January 2001 to September 2008, 102 patients received HSCT. The differences of the survival rate, relapse rate and incidence of interstitial pneumonia (IP) between groups regarding different genders, ages, pathological types, transplantation methods and TBI parameters were compared and the factors related with the survival rate, relapse rate and incidence of IP were analyzed. Results The followup time ranged from 15 to 1482 days (median, 406 days). The follow-up rate was 95.1%. 86 and 55patients were followed up more than one year and three years. The 1-and 3-year survival rates were 59.0%and 44.0%. In univariate analysis, the 3-year survival rate was signifcantly different between the groups with and without relapse before transplantation (20% vs. 55%, χ2 = 6.33, P = 0. 012), allogeneictranplantation versus autologous tranplantation (39% vs. 68%, χ2 = 8.06, P = 0.005), grade 3 or more acute graft versus host disease (aGVHD) and grade 0 -2 aGVHD (0% vs. 54%, χ2 = 7.52, P = 0.006),with and without relapse after transplantation (19% vs. 58%, χ2 = 10.13, P =0.001), with and without IP (23% vs. 58%, χ2 =8.35, P=0.004). Multivariate analysis showed that grade 3 or more aGVHD was the only statistically significant prognostic factors (χ2 = 12. 74 ,P =0. 000). The l-and 3-year relapse rateswere 30. 0% and 50. 0%. The incidence of relapse was obviously higher in the group with relapse before transplantation than that without (47% vs. 16%, χ2 =7. 32, P=0. 007). Multivariate analysis showed thatrelapse before transplantation was a significant factor predicting relapse after transplantation (χ2 = 9. 39,P =0. 020). The cumulative incidence of IP was 35.0%. The incidence of IP was different between groups with dose homogeneity > 3% and ≤ 3% (27% vs. 4%, χ2 = 5. 21, P = 0. 023), with and without acute parotitis (34% vs. 3%, χ2 = 14. 15, P= 0.000), allogeneic transplantation group and autologous transplantation group (31% vs. 8%, χ2= 7.70, P= 0.006). Multivariate analysis showed that transplantation methods, acute parotitis and dose homogeneity were statistically significant factors in predictingIP (χ2 = 10. 08 , 10. 08 and 7.69 , P = 0. 002 , 0. 002 and 0. 010 , respectively) . Conclusions Patients who develop grade 3 or higher aGVHD have poor prognosis. Dose homogeneity influences the incidence of IP. Patients undergoing allogeneic transplantation are apt to have IP. Acute parotitis is related with IP and might be a predictor.

Objective To evaluate the prognosis and side-effects of three-dimensional conformal radiotherapy (3 DCRT) and intensity modulated radiotherapy (IMRT) for prostate carcinoma. Methods From 2001 to 2009, 62 patients with prostate carcinoma treated with radiotherapy were included in the retrospective analysis. Among them, 60 patients received IMRT while the other two received 3DCRT. There were 56 patients receiving androgen deprivation therapy before radiotherapy. The median dose was 78 Gy to 95% planning target volume (PTV) of the prostate and seminal vesicles, and the median dose to 95% PTV of the pelvic lymph nodes was 48 Gy. Results The median follow-up was 15.4 months. The 3-and 5-year overall survival (OS) rates were 92% and 83%, with the corresponding biochemical disease-free survival rates of 87% and 69%, and the distant metastasis-free survival (DMFS) rate of 77% and 55%, respectively. Patients with a PSA nadir ≤ 2 ng/ml had a 3-year OS of 94% and DMFS of 88%, compared with 56% and 11% (χ~2 = 16. 39, P < 0.01 for OS ; χ~2 = 28. 87, P < 0. 01 for DMFS) for those with a PSA nadir > 2 ng/ml. The incidence of grade 1 and 2 urinary toxicity was 32% and 0% for acute damage, 10% and 0% for late damage, respectively. The incidence of grade 1 and 2 intestinal toxicity was 19% and 3%. for acute damage, 5% and 3% for late damage, respectively. Conclusions Radiation therapy for patients with prostate carcinoma shows satisfactory outcomes with a good toleration. Monitor of PSA after radiotherapy has benefit for prognosis evaluation.

Objective:
To explore the moderating role of estradiol in the relationship between parenting styles and preschool children's behavioral problems, so as to provide a theoretical basis for improving the development of human s emotional health development in early life stage.
Methods:
During September to November in 2022, 354 children aged 3-6 years and their parents from two kindergartens in Bengbu City were chosen by using stratified cluster sampling method for the questionnaire survey. The Parenting Style Scale and the Child Behavior Checklist (CBCL) were used to collect information on parenting style and child behavioral problems. Salivary estradiol of children was collected and tested. Independent samples t test was applied to compare the scores of the scale for parental up bringing and children s behavioral problems, and Pearson correlation analysis was conducted to explore the relationship among parental upbringing, estradiol and children s behavioral problems.
Results:
Parents doting, laissez faire, autocratic, and inconsistent parenting styles were positive associated with child behavior problems( r =0.14-0.70); fathers democratic parenting style was negatively associated with child behavior problems( r =-0.14,-0.22,-0.21,-0.17,-0.27,-0.20); mothers democratic parenting styles was negatively correlated with scores on all five dimensions of child behavior problems except the withdrawal dimension ( r =-0.14,-0.12,-0.13,-0.21,-0.12)( P <0.05). Estradiol levels had significant moderating effects on maternal doting parenting style and children s withdrawal ( β =0.68) as well as social problems ( β =-1.00), also moderating laissez faire parenting styles and children s withdrawal problems ( β =0.75)( P <0.05). For children with low levels of estradiol, withdrawal problem scores were negatively associated with mother s doting parenting style and positively associated with laissez faire parenting style, and socialization problem scores were associated with mother s doting parenting style; for children with high levels of estradiol, withdrawal problem scores were positively associated with mother s doting parenting style, and socialization problem scores were associated with mother s doting parenting style ( t=2.84, 6.24, 3.16 , 2.37, 4.49, P <0.05).
Conclusions
Parenting styles are strongly associated with child behavioral problems; estradiol levels play a moderating role in mothers doting, laissez faire parenting styles and children s withdrawal problems and social problems.Parents should adopt more positive parenting styles and focus on the role of estradiol levels in maternal education to reduce the occurrence of behavioral problems in children.

BACKGROUND:
Cancer stem-like cells (CSCs) are a small subset of cells in tumors that exhibit self-renewal and differentiation properties. CSCs play a vital role in tumor formation, progression, relapse, and therapeutic resistance. B7-H3, an immunoregulatory protein, has many protumor functions. However, little is known about the mechanism underlying the role of B7-H3 in regulating gastric cancer (GC) stemness. Our study aimed to explore the impacts of B7-H3 on GC stemness and its underlying mechanism.
METHODS:
GC stemness influenced by B7-H3 was detected both in vitro and in vivo . The expression of stemness-related markers was examined by reverse transcription quantitative polymerase chain reaction, Western blotting, and flow cytometry. Sphere formation assay was used to detect the sphere-forming ability. The underlying regulatory mechanism of B7-H3 on the stemness of GC was investigated by mass spectrometry and subsequent validation experiments. The signaling pathway (Protein kinase B [Akt]/Nuclear factor erythroid 2-related factor 2 [Nrf2] pathway) of B7-H3 on the regulation of glutathione (GSH) metabolism was examined by Western blotting assay. Multi-color immunohistochemistry (mIHC) was used to detect the expression of B7-H3, cluster of differentiation 44 (CD44), and Nrf2 on human GC tissues. Student's t -test was used to compare the difference between two groups. Pearson correlation analysis was used to analyze the relationship between two molecules. The Kaplan-Meier method was used for survival analysis.
RESULTS:
B7-H3 knockdown suppressed the stemness of GC cells both in vitro and in vivo . Mass spectrometric analysis showed the downregulation of GSH metabolism in short hairpin B7-H3 GC cells, which was further confirmed by the experimental results. Meanwhile, stemness characteristics in B7-H3 overexpressing cells were suppressed after the inhibition of GSH metabolism. Furthermore, Western blotting suggested that B7-H3-induced activation of GSH metabolism occurred through the AKT/Nrf2 pathway, and inhibition of AKT signaling pathway could suppress not only GSH metabolism but also GC stemness. mIHC showed that B7-H3 was highly expressed in GC tissues and was positively correlated with the expression of CD44 and Nrf2. Importantly, GC patients with high expression of B7-H3, CD44, and Nrf2 had worse prognosis ( P = 0.02).
CONCLUSIONS
B7-H3 has a regulatory effect on GC stemness and the regulatory effect is achieved through the AKT/Nrf2/GSH pathway. Inhibiting B7-H3 expression may be a new therapeutic strategy against GC.
