OBJECTIVETo compare the difference of clinical efficacy on sleeping disorder in the children with encephalopathy between the combined therapy of acupuncture at head points and seed-pressure at ear points and the simple acupuncture at head points.

METHODSThirty cases of sleeping disorder induced by encephalopathy werei randomized into an observation group and a control group, 15 cases in each one. In the observation group, the combined therapy of acupuncture at head points and seed-pressure at ear points was adopted. The head points in cluded Sishencong (EX-HN 1), Shenting (GV 24) and Benshen (GB 13). The ear points were the positive reactive sites in the cymba and cavum conchae. In the control group, acupuncture was applied simply to the acupoints on the head. The treatment was given once on every Tuesday and Friday a week separately, 30 min each time. Totally, 16 treatments were required. Children's sleeping habit questionnaire (CSHQ) was used to observe the sleep improvements and the efficacy in the patients of the two groups.

RESULTSIn the observation group, the results of sleep resistance, sleep anxiety, night sleep wake, parasomnias, sleep dyspnea, daytime somnolence and the total score after treatment were all improved apparently as compared with those before treatment (all P<0. 05). In the control group, the results of night sleep wake, parasomnias, daytime somnolence and the total score after treatment were improved apparently than those before treatment (all P<0. 05). In the observation group, the results of sleep resistance, sleep dyspnea and the total score after treatment were better than those in the control group (all P<0. 05) and the scores of sleep anxiety and daytime somnolence in the control group were better than those in the observation group after treatment (both P<0. 05).

CONCLUSIONThe combined therapy of acupuncture at head points and seed-pressure at the positive reactive sites in the cymba and cavum conchae achieves the superior efficacy on sleep resistance and sleep dyspnea as compared with the simple acupuncture. The efficacy of simple acupuncture is more satisfactory on sleep anxiety and daytime somnolence.

Objective To study the over-expression and clinical implications of the oncogene MDM2 in acute leukemia (AL). Methods The expression of MDM2 gene in 100 patients with newly diagnosed and relapse or refractory AL and 20 healthy as control was measured by relative quantitative reverse transcriptase polymerase chain reaction (RT-PCR),then the results was measured by χ2-test,t-test and one-way ANOVA to compare expession positive rate and intensity of MDM2. Results Among 100 patients,fifty-eight had the high expression of MDM2 gene (58 %). The expression level of MDM2 gene in patients was higher than that of health controls(P ＜0.05). The expression positive rate of MDM2 is higher in poor outcome group (67.9 %,19/28)than that in general outcome group (33.9%,19/56) (P＜0.05). Conclusion Our results suggest that the expression of MDM2 gene plays an important role in the pathogenesis and poor outcome of AL.

Abstract： Objective　To establish a screening-diagnosis-evaluation system of neonatal congenital heart disease (CHD) suitable for Hainan Province based on the application of percutaneous blood oxygen saturation measurement and cardiac auscultation screening, and to provide a basis for further promotion of the evaluation effect. Methods　Screening agencies (all midwifery institutions) used the "double index method" to screen newborns for congenital heart disease. Those who were screened positive for any index were transferred to diagnostic institutions (the people's hospitals of all cities and counties and some tertiary hospitals) for echocardiography examination within 1 week. Those with abnormal results were transferred to the treatment institution (two tertiary hospitals) for reconfirmation and evaluation. All data were managed online. Results　In this study, 96 913 newborns born in midwifery institutions in 19 cities and counties were screened, with a response rate of 99.44%. The ratio of male infants (50 836) to female infants (46 077) was 1.10∶1. A total of 2 284 positive patients were screened by dual index method, and ultrasound diagnosis was performed, with the rate of cardiac ultrasonography of 98.07% (2 240/2 284) and a high response rate. A total of 238 cases of congenital heart disease were diagnosed (incidence rate of 0.25%), with the top three main types were ventricular septal defect, atrial septal defect, and patent ductus arteriosus. The sensitivity (88.24%) and Youden index (0.86) of dual-indicator screening for CHD detection were significantly higher than the other separate indicators. Through Kappa consistency test analysis, the consistency of dual-indicator screening with simple heart murmur screening results was excellent, with a Kappa coefficient value of 0.835 (>0.75); the consistency of dual-indicator screening and simple POX screening results was good, with a Kappa coefficient value of 0.429 (between 0.40-0.75), and the differences were statistically significant (P<0.001). By the end of the study, 136 children had undergone open-chest/occlusion surgery, with good postoperative recovery, and the rest were followed up. Conclusions　The neonatal CHD screening-diagnosis-assessment technology system established in this study, with close connections between various blocks, high screening response rate and echocardiography examination rate, is beneficial for the early diagnosis and treatment of CHD children, and has certain application value in institutions at all levels in Hainan Province, and is worth further promotion.

BACKGROUND:Apoptosis of islet cel s is closely related to the long-term hyperglycemia-and hyperlipemia-induced injuries. OBJECTIVE:To observe the effect of Shizidaiping formula on the apoptosis and insulin secretion in MIN6 cel s under the high glucose and lipid environment, and to explore the protective effect of Shizidaiping formula and the related apoptosis mechanism. METHODS:MIN6 cel s were divided into normal, model, melbine, low-, medium-and high-dose Shizidaiping formula groups. The cel activity was examined by cel counting kit-8, the insulin secretion was measured by ELISA, the rate of apoptosis was measured by Annexin V-FITC&PI and the expression levels of MEK1/2, ERK1/2 and p-ERK1/2 were examined by western blot assay. RESULTS AND CONCLUSION:Shizidaiping formula significantly improved MIN6 cel activity under high glucose and lipid condition (P<0.05), decreased early cel apoptosis, increased the level of insulin stimulated by low glucose in cel supernatant (P<0.05), and improved the expression levels of MEK1/2, ERK1/2 and p-ERK1/2 (P<0.05). These results suggest that Shizidaiping formula can protect islet cel s from hyperglycemia and hyperlipemia damage by improving the activity of MIN6 cel s, reducing the insulin secretion and inhibiting the apoptosis of pancreaticβcel s in MIN6 cel s.

Abstract: Objective To explore the trend of maternal mortality in Hainan Province during the period of 2003-2022, both in the province and in urban and rural areas, and to forecast the maternal mortality rate for the period 2023-2025. Methods The 2003-2022 data collected from Hainan Province's three-tier network for maternal mortality surveillance was examined using the Chi-square test for trend (CMH) to analyze the province-wide and urban-rural maternal mortality trends. The time series model forecasting using exponential smoothing was used to predict the maternal mortality rate in Hainan Province from 2023 to 2025. Results　From 2003 to 2022, a total of 201 011 616 live births and 463 maternal deaths were reported in Hainan Province, with a maternal mortality rate of 23.03 per 100 000. Over 20 years, the maternal mortality rate in Hainan Province showed a downward trend, with an annual rate of decline of -4.13%. The rate decreased significantly during this period.. From 2003 to 2022, the maternal mortality rate in rural areas of Hainan Province was 25.74/100 000 (373/1 448 943), and it was significantly higher than that in urban areas, 16.04/100 000 (90/561 173). In the first 10 years, the gap between urban and rural areas progressively reduced, but it widened significantly in the last decade, especially after 2017. The maternal mortality rate was significantly lower in urban than rural areas, and the differences had statistical significance. The annual rates of decline in maternal mortality in Hainan Province and in urban and rural areas from 2003 to 2022 were -5.0% and -3.71%, respectively, showing a negative growth with the decrease rate in rural areas lower than urban areas. The maternal mortality rate in Hainan Province showed a fluctuating downward trend, different from the stable trend of national decrease. The mortality rates for direct obstetric causes of death (233 cases) and indirect obstetric causes of death (230 cases) were 11.59/100 000 and 11.44/100 000, respectively. The results of the maternal mortality review showed a predominance of avoidable deaths (315 cases, 68.03%). Brown's cubic exponential smoothing predicted the maternal mortality rate in Hainan Province for 2023-2025 as 9.45/100 000, 8.17/100 000, and 6.89/100 000. Conclusions　The maternal mortality rate in Hainan Province is largely influenced by maternal deaths in rural areas, and maternal health care in rural areas should be emphasized. Measures such as intervening to address the main factors influencing avoidable maternal deaths, strengthening high-risk maternal management, improving the level of critical maternal care, and providing subsidies for critical maternal care can sustainably reduce the maternal mortality rate in Hainan.

Abstract: Objective　To evaluate the free thalassaemia screening programme for preconception and pregnancy in Hainan Province, and to provide a theoretical basis for optimizing the screening process for thalassaemia. Methods From November 2020 to July 2021, a survey was conducted on 10 396 adults with Hainan household registration who participated in the Epidemiological Survey of Thalassemia in Hainan Residents in 19 cities and counties of Hainan Province. All of them underwent routine blood tests, haemoglobin electrophoresis tests and genetic tests for thalassaemia. The optimal diagnostic cut-off values for mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and haemoglobin adult type 2 (HbA2) were determined using screening test indexes such as receiver operating characteristic curve and sensitivity. The diagnostic effectiveness of different primary screening programs for thalassemia gene carriers was evaluated. Results Using the existing MCV single-indicator thalassemia primary screening protocol in Hainan Province, where individuals with MCV<82 fL undergo thalassemia gene testing, resulted in a high missed diagnosis rate (34.06%) and low sensitivity (65.94%). The optimal cut-off values for MCV screening for alpha-and beta-thalassaemia were 84.45 fL and 79.05 fL, respectively; the optimal cut-off values for MCH screening for alpha-and beta-thalassaemia were 27.95 pg and 25.15 pg, respectively. The optimal cut-off value for HbA2 screening for alpha-thalassaemia was less than 2.55% and greater than 3.35% for beta-thalassaemia. The "combined HbA2 or MCH or MCV screening protocol" with the cut-off values recommended in this study had a better performance in primary screening for thalassemia, with the highest sensitivity (92.96%) and negative predictive value (92.67%) and the lowest underdiagnosis rate (7.04%), statistically significant differences compared with the existing protocol (P<0.05). Conclusions The current process of screening for thalassemia in Hainan Province may lead to missed diagnoses. The combined use of MCV, MCH and HbA2 for thalassemia screening, adopting locally suitable cutoff values for primary screening indicators, can improve the incidence of missed reporting of thalassemia and enhance diagnostic effectiveness.

The corona virus disease 2019 (COVID-19) caused by the new coronavirus (SARS-CoV-2) has spread rapidly around the world,posing a serious threat to the public"s health. As of September 30,2020,the number of infected people in the world has reached 33 million,causing more than 1 million deaths. Normalized nucleic acid detection methods based on lab have long turnaround time and high cost. Therefore,there is an urgent need to develop a convenient method to detect SARS-CoV-2,so as to achieve rapid testing and timely control of the epidemic when resources are limited.This review summarizes the point-of-care testing (POCT) methods developed for SARS-CoV-2 in terms of extraction,amplification and detection,and briefly introduces commercial POCT instruments that integrate these three steps,in order to provide references for emergency response and rapid deployment of COVID-19 and other emerging infectious diseases.
