Objective:To learn about the status of thyroid function and intelligence quotient (IQ) of children in areas with different iodine nutrition levels in Xinjiang Uygur Autonomous Region, and to explore the health risk of children with median urinary iodine of 200 - 299 μg/L, and to provide a basis for scientific iodine supplementation.Methods:In May 2019, in Xinjiang Uygur Autonomous Region, Altay Prefecture and Kashgar Prefecture were selected, where the median urinary iodine of children aged 8 to 10 years were 100 - 199 and 200 - 299 μg/L for three consecutive years (2017 - 2019). A stratified random sampling method was used to select 400 children aged 8 to 10 years in each of the two regions, urine and blood samples were collected to detect urinary iodine and thyroid function [thyrotropin stimulating hormone (TSH), free thyroxine (FT 4), free triiodothyronine (FT 3), anti-thyroglobulin antibody (TgAb), and anti-thyroperoxidase antibody (TPOAb)]. At the same time, children's IQ was measured and determined by Second Revision of Combined Raven's Test (CRT-C2) in China and Second Revision of Combined Raven's Test for Children-the Rural, in China (CRT-RC2). Results:The median urinary iodine of children aged 8 to 10 years in Altay Prefecture and Kashgar Prefecture was 188.6 and 250.1 μg/L, respectively. There was no statistically significant difference in thyroid function indexes TSH and FT 3 levels between the two regions ( Z = - 0.58, t = 0.49, P > 0.05), while there was statistically significant difference in FT 4 level ( t = 60.08, P < 0.001). There was no statistically significant difference in TgAb positive rate [3.6% (14/394), 4.0% (16/399)] between the two regions (χ 2 = 0.11, P = 0.736), but the difference of TPOAb positive rate [9.6% (38/394), 30.6% (122/399)] was statistically significant (χ 2 = 53.93, P < 0.001), while the difference of dual antibody positive rate [0.8% (3/394), 2.0% (8/399)] was not statistically significant ( P = 0.134). There was no statistically significant difference in the detection rates of subclinical hypothyroidism [8.9% (35/394), 11.0% (44/399)], subclinical hyperthyroidism [1.0% (4/394), 1.3% (5/399)] and hyperthyroidism [0.3% (1/394), 0.8% (3/399)] in children between the two regions ( P > 0.05). The IQ results of children in the two regions were 96.55 ± 11.36 and 89.57 ± 12.35, respectively, and there was no significant difference between them ( t = 2.79, P = 0.095). Conclusions:The thyroid function status of children is similar in the two regions with median urinary iodine of 100 - 199 μg/L and 200 - 299 μg/L in children aged 8 to 10 years, but the TPOAb positive rate is significantly different. Children whose iodine nutritional level is at or above the appropriate level have no obvious changes in intelligence. It is suggested that median urinary iodine at 200 - 299 μg/L is a relatively safe iodine nutrition state.

In designated hospitals for critical patients with COVID-19 in Wuhan, time-efficient pharmaceutical emergency protection system was of great significance for epidemic prevention. Described in the paper are measures taken by the pharmaceutical department of the hospital as follows. These measures include launching an emergency response mechanism, formulating a catalogue of COVID-19 key therapeutic drugs, urgently purchasing therapeutic drugs, transforming the processes of emergency pharmacy, establishing a drug donation management system, building a COVID-19 pharmaceutical care team, and setting up a " cloud pharmacy" to meet the drug needs of patients with non-COVID-19 chronic diseases, in addition to strengthening personnel protection of pharmacists. During such an epidemic, the pharmacy administration works in a professional, comprehensive, complex and systematic emergency program, which guaranteed the safety of drug supply, medication and enabled the treatment to be carried out in an orderly manner.

After the outbreak of COVID-19, due to environmental pollution in the isolated ward and operational constraints caused by protective clothing and other factors, intravenous drugs in the designated hospitals should be centralized. Combined with the existing process mode, the process of pharmacy intravenous admixture services was optimized, the operation mode of the operation platform was adjusted, the scheduling mechanism was optimized, and the node control process of " first verify and five checks" was explored and developed, so as to meet the 24 h needs of COVID-19 patients. According to the characteristics of COVID-19 drug treatment, the focus of prescription review was adjusted to ensure the drug safety of patients. Other measures included implementing paperless prescription to reduce unnecessary media; implementing segmented infusion distribution management to ensure no cross infection; hierarchical control and configuration environment, strengthening the protection and management of pharmacists, to avoid the risk of personnel infection; optimizing human resource allocation and improving work efficiency. This process reengineering and optimization established the emergency management mode of centralized intravenous drug deployment under the background of COVID-19, which ensured the intravenous drug demand and safety of COVID-19 patients. The treatment work was carried out orderly, and could provide reference for the pharmaceutical department in medical institutions to deal with major public health emergencies in the future.

OBJECTIVE: To observe the effects of abdominal acupuncture and the periodic therapy of Chinese herbal medicine on follicular development and endometrial receptivity in the patients with infertility induced by ovulation failure and differentiated as kidney deficiency in TCM. METHODS: A total of 84 patients with infertility induced by ovulation failure and differentiated as kidney deficiency were randomized into a combined therapy group (27 cases), an abdominal acupuncture group (27 cases) and a western medication group (30 cases). In the combined therapy group, abdominal acupuncture and the periodic treatment of Chinese herbal medicine was provided. In the abdominal acupuncture group, the simple abdominal acupuncture therapy was used. In the western medication group, clomiphene citrate (CC) and human chorionic gonadotrophin (HCG) prescribed. The treatment for one menstrual cycle was taken as one session and 3 sessions of treatment were required except the pregnancy. The folicle development, endometrial thickness and morphology, menstrual condition and TCM symptom score were observed before and after treatment in the three groups, and the clinical efficacy was evaluated. RESULTS: After treatment, the ovulation was recovered to different degrees in the three groups. The ovulation rate was 59.3% (16/27) in the combined therapy group, 55.6% (15/27) in the abdominal acupuncture group and 53.3% (16/30) in the western medication group. The difference was not significant in comparison among the three groups (>0.05). After treatment, the endometrial thickness in the periovulatory period was increased as compared with the thickness before treatment in the combined therapy group and the abdominal acupuncture group (both <0.05). After treatment, the endometrial thickness in the combined therapy group was higher than the western medication group (<0.05). In comparison before and after treatment, the difference in the endometrial morphology was significant in the combined therapy group and the abdominal acupuncture group (both <0.05). In comparison between the combined therapy group and the western medication group, the difference in the endometrial morphology was significant after treatment (<0.05). After treatment, the menstrual condition and TCM symptom score in the combined therapy group and the abdominal acupuncture group were all improved as compared with those before treatment (all <0.05). The score of menstrual condition in the combined therapy group was higher than the western medication group (<0.05) and TCM symptom score in the combined therapy group and abdominal acupuncture group was higher than the western medication group after treatment (all <0.05). The total effective rate was 88.9% (24/27) in the combined therapy group and was 92.6% (25/29) in the abdominal acupuncture group, which was higher than 56.7% (17/30) in the western medication group (<0.01). There was no adverse reaction in the combined therapy group and the abdominal acupuncture group. CONCLUSION Abdominal acupuncture combined with the periodic therapy of Chinese herbal medicine improve the menstrual condition and relieve the clinical symptoms of infertility induced by ovulation failure of kidney deficiency in the patients and the therapeutic effects are better than the medication with CC + HCG. This combined therapy improves the ovulation rate and the endometrial receptivity at periovulatory stage to increase the pregnancy rate. There is no adverse reaction discovered in clinical practice.
