OBJECTIVETo develop a new method for predicting adult height (PAH) based on the theory of Bayley-Pinneau and to evaluate the feasibility of this method in predicting adult height of girls with idiopathic central precocious puberty (ICPP) who were treated with gonadotropin releasing hormone agonist (GnRHa).
METHOD(1) The new method for PAH, i.e. PAH = Height/percentage of adult height for bone age, was established according to the theory of Bayley-Pinneau and the data from the national growth survey of children in the nine cities of China in the year 2005. (2) Data from seventeen female patients with ICPP received GnRHa treatment and achieved final adult height (FAH) were collected. Before and during the treatment, PAH was calculated by the method of Bayley-Pinneau and the new method.
RESULTThe mean FAH(cm) of the 17 patients with ICPP was 159.81 ± 4.95. The PAH (cm), before and after treatment for 1, 2 and 3 years, were 156.53 ± 3.63, 157.71 ± 3.62, 158.60 ± 3.50, 161.46 ± 4.50 and 161.56 ± 3.77, 161.68 ± 3.44, 162.04 ± 4.42, 163.13 ± 2.36 respectively by using the new method (PAH-D) and Bayley-Pinneau method(PAH-BP). The mean value of (PAH-D-FAH) and (PAH-BP-FAH) were -1.96 cm and 1.48 cm. However, the 95% confidence interval was (-3.82 cm to -0.11 cm), (-1.60 cm to 4.55 cm) for (PAH-D-FAH) and (PAH-BP -FAH). There was no significant difference between the values obtained before and after treatment in terms of PAH by use of Bayley-Pinneau method. By the new method, however, the results showed that the PAH increased and improved further with prolonged treatment periods. And at the end of treatment, there was no significant difference between PAH and FAH. The correlation coefficient was 0.93. Regression analysis showed that the trend line was in parallel with baseline data.
CONCLUSIONThe new method we established could predict better the final heights of girls with CPP who were treated with GnRHa.

Objective:To explore the clinical value of 18F-fluoromisonidazole (FMISO) PET/CT hypoxia imaging in early response to heavy ion radiotherapy in patients with non-small cell lung cancer(NSCLC). Methods:From April 2018 to January 2021, the 18F-FMISO PET/CT images of 23 NSCLC patients (19 males, 4 females; age (64.9±10.3) years) who received heavy ion radiotherapy in Shanghai Proton and Heavy Ion Center were retrospectively analyzed. The evaluation parameters included tumor volume (TV), tumor to background ratio (TBR) before and after radiotherapy. Patients were divided into hypoxia group and non-hypoxia group with the baseline TBR value≥1.4 as hypoxia threshold. Wilcoxon signed rank test was used to compare the differences of TV and TBR before and after radiotherapy in 2 groups. Results:Of 23 NSCLC patients, 17 were hypoxia and 6 were non-hypoxia. Compared with the baseline, TV after the radiotherapy (59.44(22.86, 99.43) and 33.78(8.68, 54.44) cm 3; z=-3.05, P=0.002) and TBR after the radiotherapy (2.25(2.09, 2.82) and 1.42(1.24, 1.67); z=-3.39, P=0.001) of the hypoxia group were significantly lower, while TV (16.19(6.74, 36.52) and 8.59(4.38, 25.47) cm 3; z=-1.57, P=0.120) and TBR (1.19(1.05, 1.27) and 1.10 (0.97, 1.14); z=-1.89, P=0.060) of the non-hypoxia group decreased with no significant differences. Conclusions:Hypoxic NSCLC tumors are sensitive to heavy ion radiation. Compared with non-hypoxic tumors, hypoxic tumors respond more quickly, and a significant reduction in TV can be observed early after radiotherapy. Heavy ion radiation can significantly improve tumor hypoxia.

177Lu-prostate specific membrane antigen(PSMA)radio-ligand therapy has been approved abroad for advanced prostate cancer and has been in several clinical trials in China.Based on domestic clinical practice and experimental data and referred to international experience and viewpoints,the expert group forms a consensus on the clinical application of 177Lu-PSMA radio-ligand therapy in prostate cancer to guide clinical practice.
