Objective To propose prevention and control strategy against iodine deficiency disorders to prevent new cases of endemic cretinism from occurring. Methods In April and August 2007, all the suspected cretinism patients born after the first of January, 1997 were searched for in 16 counties from Lhasa, Shannan, Nyingchi, Qamdo and Xigaze. Meanwhile, 60 children aged 8-10 years were selected in each of the two rural villages of each county chosen. Goiter was examined using palpation and B-ultrasound, urinary iodine was determined, inteligence quotient(IQ) was tested; 30 women of childbearing age from each village chosen underwent urinary iodine test and household salt semi-quantitative detection. Results No new cases of endemic cretinism had been found; Palpation identified goiter at 4.5% (257/5680) in children, B-ultrasound revealed a rate of 4.7% (258/5433). Median of urinary iodine was 159.4 μg/L, the averaged IQ was 78.3±14.5; women of childbearing age had a median urinary iodine of 70.2 μg/L. The coverage rate of iodized salt was 52.8%. Conclusions Goiter rate in children, urinary iodine level meet the standard set for the elimination of iodine deficiency disorders; however, the low IQ children, low coverage of iodized salt and the level of urinary iodine in women of childbearing age are less than desirable. Iodine deficiency disorders prevention and control need to be strengthened.

To construct and validate a deep learning-based bone age prediction model for children living in both plain and highland regions. A model named "ethnicity vision gender-bone age net (EVG-BANet)" was trained using three datasets, including the Radiology Society of North America (RSNA) dataset [training set( EVG-BANet exhibited MAD of 0.34 and 0.52 years in RSNA and RHPE test sets, respectively. In the self-established test set, the model achieved MAD of 0.47 years (95% CI: 0.43-0.50) with accuracy within 1 year of 97.72% (95% CI: 95.56-99.01%). For the external test set, MAD was 0.53 years(95% CI: 0.48-0.58), with accuracy within 1 year of 89.45% (95% CI: 85.03-92.93). EVG-BANet demonstrated high accuracy in bone age prediction, and therefore can be applied in children living in both plain and highland.

Objective To investigate the risk factors of relapse in patients with ischemic stroke using aspirin for single drug antiplatelet therapy.Methods A retrospective analysis was conducted on 200 patients with mild and medium ischemic stroke after 12 months of single drug treatment with aspirin,and the patients were divided into non-recurrence group and recurrence group according to the recurrence of stroke.Univariate analysis and multivariate logistic regression model were used to explore whether the related indicators were risk factors for recurrence.The ROC curve was used to predict the critical value of risk factors.Results Univariate analysis showed that platelet count,Hcy level and the A allele at rs12041331 site of PEAR1 gene were statistically significant risk factors(P<0.05).Multifactor analysis showed that the independent risk factor for recurrence was homocysteine level[OR = 1.16(1.089-1.240),P<0.001)].The critical value of ROC prediction was 8.35 μmol/L(sensitivity 0.847,specificity 0.532).Conclusions The Hcy level,platelet count and A allele at rs12041331 site of PEAR1 gene are risk factors for recurrence in patients with ischemic stroke treated with aspirin for Single drug antiplatelet therapy.Hcy level is independent risk factor and can be used to predict the risk of recurrence.

Tibetan medicine is an essential part of Chinese medicine and has unique theoretical experience and therapeutic advantages. According to the development principle of inheriting the essence, sticking to the truth, and keeping innovative, the supervision department should give clear and reasonable guidance considering the characteristics of Tibetan medicine, establish a standard system for quality control, clinical verification and evaluation, and accelerate the research and commercialization of new drugs. In view of the needs of drug supply-side reform and the current situation of Tibetan medicine and new pharmaceutical research, we ponder and provide suggestions on the confusion faced by the current supervision of Tibetan drug registration, hoping to contribute to the supervision strategy of Tibetan drug registration and the high-quality development of Tibetan medicine industry.
