Objective:To analyze the influence of clinicopathological features on the prognosis of anorectal malignant melanoma (AMM), and to establish a more accurate prognosis prediction model.Methods:From January 1, 2006 to December 31, 2018, at Fudan University Shanghai Cancer Center, the data of 89 patients diagnosed with AMM and underwent operation were retrospectively analyzed. The Cox proportional hazard regression model was used to analyze factors affecting the prognosis. Backward elimination was used to select variables, Nomogram prognosis prediction model was established and verified internally, and the consistency index was calculated.Results:Among 89 AMM patients, 65 (73.0%) were female, 78(87.6%) were <70 years old, and the most common tumor location was the rectum (48.3%, n=43), followed by the anal canal (31.5%, n=28) and the anorectal canal (20.2%, n=18). Thirty-eight (42.7%) patients directly received abdominal-perineal resection (APR), 37 patients (41.6%) received interferon-based immunotherapy, and 11 patients (12.4%) received both systemic chemotherapy and immunotherapy. The 3-year disease-specific survival (DSS) rate was 41.6%(37/89), and the 5-year DSS rate was 31.5%(28/89). The results of multivariate Cox analysis showed that age ≥70 years old and T2 stage were risk factors of the prognosis of AMM patients (hazard ratio ( HR)=11.29, 4.83; 95% confidence interval ( CI) 2.89 to 44.13, 1.66 to 14.11; both P<0.01), while neurovascular invasion, immunotherapy treatment, systemic chemotherapy combined with immunotherapy, APR after extensive local resection, directly APR and APR combined with inguinal lymphadenectomy were protective factors of the prognosis ( HR=0.09, 0.23, 0.10, 0.13, 0.26, 0.02; 95% CI 0.02 to 0.34, 0.10 to 0.57, 0.02 to 0.49, 0.03 to 0.52, 0.08 to 0.90, 0.00 to 0.27; all P<0.05). The Nomogram model was further established with age, gender, tumor location, T stage, distant metastasis, medication chemotherapy and surgical treatment. The results of the Nomogram model internal verification indicated that the accuracy of the model in predicting 1-year, 3-year and 5-year DSS was good, and the consistency index was 0.749, which was significantly higher than the consistency index of traditional TNM stage (0.607). Conclusions:Most AMM patients are <70 years old, and the majority of them are female. The common location of AMM is rectum, and many patients receive immunotherapy. Age ≥70 years old and T2 stage are risk factors affecting the prognosis of AMM patients. Neurovascalar invasion, immunotherapy based comprehensive treatment, APR after extensive local resection, directly APR and APR combined with inguinal lymphadenectomy are protective factors of the prognosis. Nomogram prognosis prediction model established based on the clinicopathological features and treatment of AMM patients has higher accuracy and clinical reference value than the traditional TNM stage system.

Objective To set up a method of three-dimensional breast volume measurement, to observe the effect of the artificial influencing factors on the final data, which are used for 3-D reconstruction of breast volume. Methods The CT data were used to reconstruct a digital prototype of the breast implant and the chest. The 3-D models were established firstly, and then the model was reasonablly cut to get single breast volume, breast implant volume, differences of the both sides of chest and breast volume. These methods were put up by the repeated test when the reference frame and the ranges were fixed. And the analysis of the artificial influencing factors was performed on 10 women whose breasts were unsym-metrical. The effects of the artificial influencing factors were analyzed by moving the coordinate axis, revolving the chest around the coordinate axis and changing the selected area. Results The repeatable test showed that the error was less than 4. 08 ml. The average volume differences between both sides of the breast before and after the given influencing factors were set, were 10. 339 ml and 7. 73 ml, as moved ± 4mm along the axis X; as revolving ±2° along the axis Z, that were 8. 654 ml and 7. 971 ml; as increasing or decreasing of the selected diameter of ± 4 mm, that were 6. 764 ml and 4. 267 ml, respectively. Conclusion Using the 3-D reconstruction technique for breast volume measurement is more simple, accurate and repeatable.

OBJECTIVE:To establish a method of determining the plasma concentration of capecitabine/polyethylene glycol 1000/montmorillonite (CAP/PEG1000/MMT) in rats’plasma for the study on pharmacokinetics of CAP compound in rats in vivo. METHODS:HPLC was adopted. The determination was performed on Kromasil C18 with mobile phase consisted of 0.1% glacial acetic acid-acetonitrile(73∶27),at the flow rate of 1.0 ml/min. The detection wavelength was 250 nm and column temperature was 40 ℃. The sample size was 10 μl. 18 Wistar rats were randomly divided into CAP group,CAP/MMT group(MMT as carrier)and CAP/PEG1000/MMT group(PEG1000/MMT as carrier)and ig given corresponding drugs,that equal to 200 mg/kg of CAP. Blood sample was respectively taken 15,30,60,90,120,180,240,300 and 360 min after the administration of drugs,and plasma was isolated and added with internal standard ferulic acid. The concentration of the drug in the plasma was determined by HPLC fol-lowing protein precipitation with methanol,based on which the pharmacokinetic parameters were calculated by 3p97 software. RE-SULTS:The linear range of CAP was 0.054 9-4.390 0 μg/ml (r=0.998 2) with the method recovery of 98.2%-102.1%(RSD=1.50%-3.29%, n=5) and absolute recovery of 76.2%-78.9%(RSD=2.29%-2.99%, n=5). In the above-mentioned three groups,t1/2 were(1.11±0.32),(1.57±0.32)and(1.62±0.10)h;cmax were(2.91±0.36),(0.91±0.23)and(0.91±0.14)μg/ml;AUC0-6 h were (8.70 ± 1.79),(3.76 ± 0.27) and (3.73 ± 0.25)μg·h/ml;and tmax were (0.97 ± 0.20),(1.55 ± 0.47) and (1.50 ± 0.07) h,respectively. There was no significant difference in the pharmacokinetic parameters between the CAP/MMT group and CAP/PEG1000/MMT group(P>0.05). CONCLUSIONS:The method is reliable and simple,and can be used for pharmacokinetic study of CAP/PEG1000/MMT in rats. MMT and PEG1000/MMT compound can prolong CAP acting time in the body.

AIM:To explore the association between single nucleotide polymorphism in exon 33 (E33SNP) of thyroglobulin gene and Graves ’ disease ( GD) relapse after antithyroid drug ( ATD) withdrawal .METHODS:The healthy controls (232 cases) and GD patients with discontinued treatment (243 cases) were selected.According to the time of re-lapse, the GD patients were divided into A, B and C subgroups.The A group contained 77 cases of relapse within 1 year, B group contained 86 cases of relapse 1~2 years after treatment and C group contained 80 cases without recurrence within 2 years.The genotypes of E33SNP were identified by RT-PCR.The genotype ratio of thyroglobulin between control group and observation group was comparatively analyzed , and the levels of thyroid-stimulating hormone ( TSH) , free triiodothyro-nine (FT3), free thyroxine (FT4) and thyrotropin receptor antibody (TRAb), ophthalmopathy and goiter size in A , B and C subgroups in different genotype GD patients were investigated .Moreover , cumulative efficiency for patients with different genotypes in the observation group after ATD treatment within 2 years were analyzed .RESULTS:The genotype of E33SNP between observation group and control group had no significant difference , but a significant difference between A , B and C subgroups was observed (P<0.05).The levels of TSH, FT3 and FT4, and goiter size of the patients with different geno-types had no significant difference , while the TRAb levels and ophthalmopathy presented a significant difference ( P <0.05).In addition, the cumulative efficiency within 2 years for GD patients with E33SNP T/T, E33SNP T/C and E33SNP C/C genotypes was 61.8%, 42.6% and 21.3%, respectively, all with significant differences (P<0.05).CONCLU-SION:The GD patients with E33SNP C/C genotype have significantly higher TRAb level and ophthalmopathy rate than those in the patients with E33SNP C/T and E33SNP C/C genotypes, and are more likely to relapse after ATD treatment . The GD patients with E33SNP T/T genotype show a lower recurrence rate .Therefore, combination treatment or other treat-ment modalities may be more reasonable for the GD patients with E 33SNP C/C genotype.
