Prader-Willi syndrome (PWS) is a multisystemic complex genetic disorder caused by the lack of expression of genes associated with the 15q11.2-q13 region of the paternal chromosome.There are three main types of genetic mechanisms, deletion of the paternal critical region, maternal uniparental disomy and imprinting center defect.Genetic counseling can be carried out based on different genetic mechanisms of PWS, both re-fertility assessments and prenatal diagnoses were performed on couples whose children have already had the disease.The pathogeny and mechanism of PWS are complex.The rapid development of molecular genetics and related research have provided a basis for further understanding of this disease.In this paper, the advances in the genetics of PWS were reviewed.

Objective:To explore the effect of different doses of lidocaine on recovery quality of patients with iodine-deficiency goiter after general anesthesia resection.Methods:Using a prospective design, 108 patients who underwent iodine-deficiency goiter resection in Yantai Yeda Hospital from April 2018 to April 2020 were selected as the research subjects. The patients were divided into control group (normal saline), lidocaine group A (1 mg/kg) and lidocaine group B (2 mg/kg) by random number table method, 36 cases in each group. The corresponding dose of lidocaine or the equivalent dose of normal saline was pumped into the vein after anesthesia induction and intubation for 30 minutes. The changes in the diastolic blood pressure (DBP), systolic blood pressure (SBP) and blood glucose (GLU) levels of the three groups were observed before administration, immediately after the operation, immediately after opening the eyes, immediately after extubation, and 10 minutes after extubation; at the same time, arousal and restlessness score (RS), sedation score (Ramsay), visual analogue score (VAS) and adverse reactions(coughing, nausea and vomiting, respiratory depression) occurrence were recorded.Results:At the moment of eye opening, immediately after extubation and 10 minutes after extubation, DBP (mmHg: 77.26 ± 4.85, 73.45 ± 4.37, 70.94 ± 4.45, 83.53 ± 6.19, 77.86 ± 5.33, 74.14 ± 5.20, 73.86 ± 5.73, 68.41 ± 5.16, 63.09 ± 5.24), SBP (mmHg: 129.17 ± 6.54, 121.25 ± 6.07, 116.24 ± 5.86, 137.48 ± 6.62, 129.53 ± 6.38, 123.07 ± 6.25, 125.65 ± 6.13, 117.48 ± 6.09, 108.17 ± 6.04), GLU level (mmol/L: 5.83 ± 0.36, 5.37 ± 0.29, 5.12 ± 0.26, 6.69 ± 0.34, 5.84 ± 0.30, 5.57 ± 0.27, 5.61 ± 0.32, 5.25 ± 0.31, 4.97 ± 0.28) of lidocaine group A and lidocaine group B were significantly lower than those of control group, the difference were statistically significant ( F=17.520, 25.755, 36.034, 41.028, 45.525, 74.330, 10.397, 49.756, 52.348, P < 0.05); among them, the DBP, SBP and GLU levels of lidocaine group A and lidocaine group B were lower than those of control group, and lidocaine group B was lower than lidocaine group A ( P < 0.05). The RS and VAS of lidocaine group A and lidocaine group B were significantly lower than those of control group, and Ramsay was higher than that of control group ( P < 0.05); and the RS and VAS of lidocaine group B were lower than those of lidocaine group A, the Ramsay was higher than that of lidocaine group A ( P < 0.05). The incidence of coughing, nausea and vomiting in lidocaine group A and lidocaine group B were lower than those in the control group ( P < 0.05); and there was no respiratory depression in the three groups. Conclusions:Thrity minutes after induction of anesthesia, continuous pumping of 2 mg/kg lidocaine can maintain blood pressure and GLU of patients undergoing general anesthesia for iodine-deficiency goiter, and effectively reduce restlessness, pain and adverse reactions during the recovery period. It is a satisfactory dose for thyroid surgery patients to wake up and comfortably.
