Objective To investigate the significance of thyroid function screening in high-risk pregnant women with gestational diabetes (GDM) in early pregnancy.Methods A total of 194 cases with GDM were selected as our subjects.The patients were divided into group A(three normal items,a total of 109 cases),group B (one abnormal item,a total of 57 cases) and group C (two abnormal items,a total of 28 cases).The levels of serum anti-thyroglobulin antibody (TGAb),anti-thyroid peroxidase antibody (TPOAb),serum three triiodothyronine(TT3),thyroxine (TT4),free three triiodothyronine (FT3),free thyroxine (FT4) and thyroidstimulating hormone (TSH) were screened.Results TSH levels in group A was (1.45 ± 0.43) mU/L,significantly lower than in group B and group C((1.77±0.53),(1.89±0.74) mU/L).FT4 levels in group A was (11.62±0.98) nmol/L,significantly higher in group B and group C((10.23±0.75),(9.87±0.88) nmol/L)).Proportion of TPOAb,TGAb positive in group A were 9.17％(10/109) and 21.05％(12/57),significantly lower than that of group B and group C((28.57％(8/28) and 3.67％(4/109),7.02％(5/57) and 17.86％(5/28)).And the differences were significant (P＜ 0.05).And TPOAb + TGAb in group A was 0.92％(1/109),significantly lower than that of group B and group C(7.02％ (4/57),17.86％ (5/28);P ＜0.05).Conclusion The importance of screening thyroid function in early pregnancy in women at high risk for gestational diabetes is worthy of clinical promotion.

Objective To discuss the X-knife radiosurgery (XKS) in the treatment of brain metastasis of lung carcinoma. Methods A total of 100 patients with similar prognostic factors were divided into two groups with 50 patients in each group, receiving either whole-brain radiotherapy alone (30~40 Gy/3~4 weeks) (Radiotherapy Group) or XKS combined with radiotherapy (Combination Group). In the Combination Group, 27 patients received XKS with single fraction of radiation, with a median prescription dose of 14.2 Gy, and the other 23 patients received multiple fractions of radiation (5~10 Gy/f, 3 times weekly), with a total dose of 15~30 Gy. Results In the Combination Group and the Radiotherapy Group, the median survival time was 16.4 and 10 months, respectively (P=0.0064), the 2-year local tumor control rate was 88% (44/50) and 44% (22/50), respectively (?2=21.569,P=0.000), and the effective rate under CT or MRI scanning at 1~3 months after treatment was 87.5% (35/40) and 52.2% (24/46), respectively (?2=16.497,P=0.001). An analysis on the cause of death showed that 11.9% of patients (5/42) in the Combination Group died from brain metastasis, which was significantly lower than that in the Radiotherapy Group (55.6%, 25/45) (?2=25.908,P=0.000). The incidence of complications was not significantly different between the Combination Group (8%, 4/50) and the Radiotherapy Group (4%, 2/50) (?2=0.709,P=0.400). Conclusions Combined use of X-knife radiosurgery and routine radiotherapy has better therapeutic effects than radiotherapy alone for treating brain metastatic tumor.

Objective To investigate the relationship of placental vascular anastomosis and physical development and morbidity of the disease in twin neonates.Methods Fourteen pairs of twin neonates deliveried from Sep.2005 to Aug.2009 were enrolled in Newborn Intensive Care Unit,the Third Affiliated Hospital of Zhengzhou University.These twins were divided into 2 groups according the conditions of placental vascular anastomosis:significant placental vascular anastomosis group(group A) and no significant vascula anastomosis group(group B).Birth weight,head circumference,length,the morbidity of disease were all investigated in 2 groups.Clinic follow-up included neonatal behavioral neurological assessment(NBNA) and children′s development center of China(CDCC).The correlation of neonates placental vascular anastomosis between twin neonates were compared.Results There were statistically significant differences between group A and group B in birth weight,head circumference and body length(t=6.070,5.237,5.784,Pa

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 compare the planning systems of the simplified manual intensity modulated (SMIM) irradiation and standard tangential (ST) irradiation,in order to explore the application of SMIM technique in clinic.Methods In 64 cases of breast cancers after breast conserving surgery,each underwent both SMIM and ST planning systems.SMIM planning was designed by copying additional fields for shielding the high dose areas from internal or lateral tangential field.The high dose areas were reduced by adjusting the size of the additional field and open tangential field.To optimize the SMIM planning,3 high dose areas (＞ 103% ,＞ 105% and ＞ 107%) were shielded and 3 protocols carried out.The wedges were also optimized in ST plan.The target coverage and dose homogeneity and dose of organ at risk were compared between SMIM and ST planning systems.Results When the dose was normalized to cover the volume of 95% CTV,85% of the shielded areas in optimal SMIM planning were that of ＞ 103% high dose area,and 94% of target area was covered.The study on the volume of breast CTV showed that,in the large breast group,SMIM could not only significantly reduce the high dose areas,and the maximum dose as well as the dose of organ at risk,but also enhance the dose homogeneity index.However,no such effect was not significant in the small breast group.Conclusions The simplified manual intensity modulated technique can improve target dose homogeneity in the large breast cases instead of the standard tangential technique.

Combining the structural features of picotamide and linotroban, a series of N,N'-bis-(halogenophenyl)-4-methoxybenzene-1, 3-disulfonamides were designed and synthesized on the basic principles of drug design. The structures of target compounds were confirmed by IR, 1H NMR and HR-MS, and the in vitro antiplatelet aggregation activity was evaluated by Born turbidimetric method with adenosine diphosphate (ADP) as the platelet aggregation inducers. The assay results showed that twelve compounds (4b, 4f, 4l, 5b, 5d-5g, 5j, 5k, 5m and 5n) were found to have superior anti-platelet aggregation activities than the positive drug picotamide. The preliminary structure-activity relationship (SAR) has been explored.

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.

Cassiae Semen is a common traditional Chinese medicine, and contents of anthraquinones of Cassiae Semen different significantly from area to area. According to Chinese Pharmacopoeia (2010 edition), only contents of aurantio obtusin and chrysophanol were used to evaluate the quality of Cassiae Semen, another data could be added later. Ten batches of Cassiae Semen from different areas were determined, and total anthraquinones, total free anthraquinones and total combined anthraquinones contents were assessed by ultraviolet visible spectrophotometer, contents of aurantio obtusin, rhein, aloe emodin, emodin, chrysophanol and physcion were determined by HPLC. After that, principal components analysis was used to evaluate these data determined previous by dimension reduction analysis. At last, the result suggests that three main components were found out, it shows that content of aloe emodin could be used to evaluate the quality of Cassiae Semen as well as contents of aurantio obtusin and chrysophanol. And Cassiae Semen from Hebei province posseses higher quality than Cassiae Semen from other different areas. All these results can provide a good reference for quality evaluating of Cassiae Semen medicinal materials at a certain extent.
