Objective:To analyze the monitoring results of iodine deficiency disorders (IDD) in Hainan Province from 2011 to 2023, key prevention and control measures taken during this period, and the impact of related events on the monitoring results.Methods:From 2011 to 2023, a systematic sampling method was used to divide 21 cities (districts, counties) in Hainan Province into 5 districts based on east, west, south, north, and center each year. One township (street) was selected from each district, and 40 children aged 8 - 10 (non boarding students) and 20 pregnant women were selected from each township (street) for determination of iodine level of their household salt and urine samples. Based on the monitoring results, the impact of key events such as the pre reduction (2011), post reduction (implementation of new iodized salt standard, 2012 - 2023), salt industry system reform (2017), and the two-year campaign for endemic disease prevention and control (2019, 2000), on the salt iodine coverage rate and qualified iodized salt consumption rate, the urinary iodine level and its distribution in children and pregnant women were analyzed in Hainan Province. B-ultrasound was used to detect the situation of thyroid enlargement was analyzed.Results:(1) In 2011, the median iodine level in edible salt of residents in Hainan Province was 32.1 mg/kg. It was 30.8 mg/kg after the implementation of the new standard in 2012. In 2013, the salt iodine level of residents had significantly decreased to 25.9 mg/kg, with 24.5, 24.2, and 23.8 mg/kg in 2017, 2019, and 2020, respectively. The differences of median salt iodine levels between different years were statistically significant ( H = 29.01, P < 0.001). The coverage rate of iodized salt among residents in Hainan Province from 2011 to 2023 was 98.08% (80 727/82 308), and the difference between different years was statistically significant (χ 2 = 9.51, P = 0.023). The consumption rate of qualified iodized salt was 95.65% (78 738/82 308), and the difference between different years was statistically significant (χ 2 = 21.80, P < 0.001). (2) The median urinary iodine level of children from 2011 to 2023 was 177.5 μg/L, with a median of 204.2 μg/L in 2011. After the implementation of the new standard, the median urinary iodine level of children was 194.9 μg/L in 2012. In 2013, the median urinary iodine level in children decreased to 167.8 μg/L, and had remained within the range of 100 - < 200 μg/L thereafter. In 2017, 2019, and 2020, the median urinary iodine levels were 170.4, 172.8, and 186.3 μg/L, respectively. There was no statistically significant difference in different years ( H = 1.67, P = 0.061). The proportion of children with urinary iodine < 100 μg/L from 2011 to 2023 was 16.29% (8 740/53 634), and the proportion of children with urinary iodine between 100 and < 200 μg/L was 43.96% (23 575/53 634). The differences between different years were statistically significant (χ 2 = 21.50, 23.40, P < 0.001). The childhood goiter rate from 2011 to 2023 was 0.19% (101/53 634). (3) The median urinary iodine level of pregnant women was 153 μg/L in 2011, it was 154.7 μg/L in 2012 after the implementation of the new standard, and it had remained within the range of 100 - < 150 μg/L since then. The median urinary iodine level of pregnant women was 126.2 μg/L in 2013. The median urinary iodine level in 2017, 2019 and 2020 were 123.5, 133.8, and 135.4 μg/L, respectively. There was a statistically significant difference in the median urinary iodine levels of pregnant women between different years ( H = 92.10, P < 0.001). From 2011 to 2023, the proportion of pregnant women with a median urinary iodine level < 150 μg/L was the highest (55.75%, 14 761/26 477). Conclusion:From 2011 to 2023, although the monitoring results of iodine deficiency disorders in children and pregnant women in Hainan Province have fluctuated, they are still in a state of continuous elimination of IDD.

The number of investigator initiated research (IIR) is increasing. But the recognition and management of IIR in China is still in its infancy, and there is a lack of specific and operable guidance for the implementation process. Based on our practical experiences, previous literature reports, and current policy regulations, the authors took prospective IIR as an example to summarize the implementation process of IIR into 14 steps, which are as the following: study initiation, ethical review, study registration, study filing, case report form design, database establishment, standard operating procedure making, investigator training, informed consent, data collection, data entry, data verification, data locking and data archiving.

Abstract：Objective To evaluate the basic development status of public health emergencies of infectious diseases in Hainan Province from 2013 to 2022, analyze the distribution and characteristics of these emergencies, as to provide important scientific basis for the study and formulation of economic health development planning policies, for the health security policies and infectious disease prevention and control strategies in Hainan Province. Methods The relevant statistical data of public health emergencies involving infectious diseases reported in Hainan Province from 2013 to 2022 were collected, and the status quo of these emergencies was analyzed by using descriptive data statistical analysis method. The ARIMA model was used to predict the number of public health emergencies reported by infectious diseases in Hainan Province from 2023 to 2025. Results From 2013 to 2022, a total of 482 public health emergencies were reported in Hainan Province, of which 426 were infectious disease public health emergencies, accounting for 88.38%, with a total of 8 876 cases, an incidence rate of 0.61%, and eight deaths, a case fatality rate of 0.09%. The major public health emergencies of infectious diseases were unclassified events and general events, accounting for 69.25% and 29.58%, respectively. The main diseases were novel coronavirus infection, chickenpox and hand, foot and mouth disease, accounting for 45.07%, 15.49% and 11.97%, respectively; in terms of time distribution, the number of reported incidents showed an upward trend over time, with a decline in 2021, and mainly had three peak periods, April, August and December, with a total of 220 cases reported; in terms of regional distribution, the major cities and counties reported were Haikou, Wanning and Wenchang, accounting for 27.46%, 19.25% and 9.86%, respectively; in terms of location distribution, the events mainly occurred in schools, accounting for 42.02% of the total number of incidents. The ARIMA(1, 1, 0) model was used to predict infectious disease public health emergencies, and the results showed that the forecast state would be stable from 2023 to 2025, with no obvious upward trend, that is, the fluctuation range of public health emergencies related to infectious diseases in Hainan Province would be stable in the next three years. Conclusion The number of infectious disease public health emergencies reported in Hainan Province from 2013 to 2022 has increased year by year, with a decline in 2021. Although the forecast shows that public health emergencies such as infectious diseases are relatively stable with no obvious upward trend, the prevention and control of the epidemic should not be taken lightly. Hainan Province should continue to increase the investment in monitoring public health emergencies, improve the information system of public disease prevention and control, and carry out real-time monitoring of public health emergencies of infectious diseases.

Objective To explore the clinical effects of the combination of the self-made negative pressure drainage and Nano-Silver dressings on postoperative infection of incision.Methods A total of 84 patients with post-operative incision infection in the First People's Hospital of Xiangtan City from January 2013 to December 2015 were selected and divided into the observation group and the control group with 42 cases in each by random number table method.The observation group was treated with self-made negative pressure device combined with Nano-Silver dressing at the early stage,while the control group was treated with iodoform gauze dressing.When the wound bed granulation grew well,the two groups were treated with calcium alginate dressing or two stage suture until healed.The inflammatory index,incision growth and therapeutic effect of the two groups were compared.Results A week after treatment,the white blood cell,C reactive protein,incisional pain score and the change cost of the observation group were (7.62 ± 2.15) × 109/L,(19.33 ± 23.46) mg/L,(2.83 ± 0.82) and (570.13 ± 33.88) Yuan,which were all lower than those of the control group,and the differences were statistically significant (t=2.592,2.695,7.497,7.752;P ＜ 0.05).100％ coverage time of the incisional granulation tissue in the observation group was (3.86 ± 1.37) d,and the healing time of the whole incision was (12.02 ± 2.80) d in the observation group,which were both lower than those in the control group,with statistical significance (t=12.669,6.954;P ＜ 0.01).Conclusions The self-made negative pressure device combined with Nano-Silver dressing is ideal for the treatment of postoperative incision infection,while improving the therapeutic effect of the patients,and reducing the healing time of the incision and the cost of changing the medicine.

Objective To investigate the home-based rehabilitation of stroke patients in China, and to compare the curative effects under different factors, so as to discuss the strategies for home-based rehabilitation. Methods A total of 234 cases of stroke patients who has been discharged from the center of rehabilitation medicine of a Class Ⅲ Grade A hospital were selected by random cluster sampling method. Family rehabilitation status of patients and their caregivers was investigated by outpatient follow-up, home follow-up and telephone follow-up survey. In the survey, the general information questionnaire, the Barthel Index (BI), the Instrumental Activities of Daily Living (IADL), the Self-perceived Burden Scale (SPBS) and the Zarit Caregiver Burden Interview (ZBI) were applied. Results The results showed that the BI score was (61.77±22.83). The average score of IADL was (7.25±6.26). The SPB score was (29.26±7.07). 91.13% of the patients in the study group had a sense of burden. The ZBI score of the caregivers was (43.97±12.28), 59.40% of which had moderate or severe burden. The result of single factor analysis showed that the differences in the scores of BI, IADL, SPBS and ZBI of patients in different gender were statistically significant (P＜ 0.05). There were significant differences in BI and IADL scores among patients of different ages, main caregivers, family rehabilitation time and caregivers' gender (P＜ 0.05). The differences in the scores of IADL and SPBS of patients with different educational level were statistically significant (P＜0.05). The differences in BI and ZBI scores of patients with different disease types were statistically significant (P＜0.05). Conclusions The family rehabilitation of stroke patients is poor. Medical workers should pay attention to the rehabilitation of patients after discharge, especially to female stroke patients, caregivers and to strengthen the rehabilitation knowledge training for male caregivers. It is suggested that community rehabilitation, family doctor responsibility system and hospital-community-family Union should be vigorously developed so as to improve the family rehabilitation of stroke patients, reduce readmission rate, increase the utilization of social resources, and improve the health level of the whole people.

Objective To evaluate the effect of a new type of fixation tape for tracheal catheter in intensive care patients.Methods A purposive sampling study was conducted. Ninety patients experienced oral tracheal intubation for mechanical ventilation, and admitted to respiratory intensive care unit (ICU) of the Second Affiliated Hospital of Nantong University from November 2015 to February 2017 were enrolled. All the patients were randomly (random number) divided into the control group and the observation group with 45 patients in each group. The patients in control group was treated with the traditional medical adhesive tape and fixation belt to fix endotracheal tube, while the patients in observation group was treated with a new type of tracheal catheter fixation tape. The fixation effect, skin complication rate, patient's comfort level, nursing workload and satisfaction were evaluated in both groups.Results There were 6 patients with mild displacement, 2 patients with moderate displacement and 1 patient with severe displacement in the control group, while there was no catheter displacement or detachment occurred in the observation group, and the difference between the two groups was statistically significant (χ2 = 2.944,P = 0.003). In the control group, there were 39 patients with facial skin redness,6 patients with facial skin damage, 36 patients with neck skin redness, and 2 patients with neck skin damage. In the observation group, there were no facial skin complications and only 2 patients with neck skin redness, and the skin complication rate was significantly higher than that of the control group (facial skin:Z = 9.173,P = 0.000; neck skin:Z = 7.549,P = 0.000). Compared with the control group, the patients' comfort levels were significantly elevated in the observation group (the intolerance patients: 9 vs. 24, the extreme discomfort patients: 4 vs. 8,Z = 3.695,P = 0.000). The total changing times of the fixation belt and operating time for each change in the observation group were significantly decreased as compared with those of control group [changing times of the fixation belt (times): 1.89±0.77 vs. 3.86±1.18, operating time for each change (minutes): 10.31±1.47 vs. 15.78±1.89, bothP < 0.01]. Nursing satisfaction in the observation group was significantly higher than that of the control group (100% vs. 33.3%,P < 0.01).Conclusions The new fixation tape for tracheal catheter could significantly reduce the catheter displacement and detachment rate, and decreasethe incidence of facial skin injury. It is easy to learn and worth to generalize clinically.

Aim To establish the rat model of Spleen-Qi deficiency, analyse the metabolic pathways and investigate the connection between the changed urinary metabolites and Spleen-Qi deficiency, in order to explore the potential mechanisms of Spleen-Qi deficiency.Methods With the binding methods of diarrhea induced by bitter and cold, abnormal of starvation and excessive tiredness, the rat Spleen-Qi deficiency model was established.Then the activity of creatine phosphokinase(CPK) was detected.The endogenous metabolites in the urine were detected by NMR, and the data were analyzed with multivariate and statistical methods.Then the metabolites were selected that could be clearly distinct in the two groups with the fold change value(>1.2) and the P<0.05 of Student′s t-test.Both the pathway analysis and enrichment analysis were performed with Metabo Analyst 3.0.Results Compared with the normal rats, the activity of CPK decreased significantly in model rats(P<0.05).A significant separation appeared in the principal components analysis(PCA) score plot when the control group and the model group were compared, indicating that the Spleen-Qi deficiency model was successfully duplicated.The 33 differential metabolites, which mainly involved in the metabolic pathways, were distinguished from the comparision of Spleen-Qi deficiency model group and control group.The metabolic pathways was related to energy metabolism, amino acid metabolism, nucleotide metabolism and disturbance of gut microbes.Conclusions The main energy metabolic pathways (tricarboxylic acid cycle, glycolysis and liquid oxidation) may be disturbed in Spleen-Qi deficiency rats.The energy supply function is suppressed, which leads to the fatigue and weight loss in rats.

Objective To observe the role of the health education model in pain self- efficacy for patients with cancer pain. Methods Sixty- four patients suffering from cancer pain were enrolled into the study and self- contrast experiment was made on each patient. The health education model was set up and health education for each patient with cancer pain was implemented. The pain, self- efficacy, cancer pain knowledge before and after the intervention were observed by Numerical Rating Scale (NRS),Chronic Pain Self- efficacy Scale(CPSS) and Cancer Pain Knowledge Questionnaire. Results NRS score were (5.38 ±0.19) points and (1.05 ± 0.11) points before and after the intervention, and there was significant difference (t =25.288, P = 0.000). Before intervention, pain management self- efficacy, physical function self- efficacy, symptom coping self- efficacy of CPSS scores were (10.38 ±0.37) , (20.97±0.81) , (16.86 ± 0.49) points, while after the intervention, the scores were (19.31± 0.30) , (33.25 ± 0.60) , (29.75 ±0.51) points, there were significant differences ( t = -33.225, -18.236, -18.235, all P = 0.000). Before and after the intervention, the answer rate of Cancer Pain Knowledge Questionnaire was 50.00%(32/64) and 87.50%(56/64), there was significant difference( χ2=20.51, P < 0.01). Conclusions To set up the health education model and implement health education for each patient with cancer pain can improve the patient′s pain management and enhance self-efficacy.

Objective To observe the clinical efficacy of acupuncture in treating malignant pleural effusion (MPE).Method Eighteen MPE patients confirmed by histopathological and/or cytological examinations were treated by acupuncture by selecting Yunmen (LU 2), Qimen (LR 14), Zhangmen (LR 13), Jingmen (GB 25), Guanyuan (CV 4), Zhongji (CV 3), Shuidao (ST 28), and Guilai (ST 29) as the major points. The treatment was given once every other day, 3 times a week, 4 weeks as a treatment course, and the therapeutic efficacy was evaluated 1 course later.Result Of the 18 patients, 6 got complete remission, 9 got partial remission, 2 achieved stable condition, while 1 didn’t respond to the treatment, and the total effective rate was 83.3%. Of the 5 cases with encapsulated pleural effusion, 2 got complete remission and 3 got partial remission, and the total effective rate was 100.0%. The amount of pleural effusion (anteroposterior diameter of the fluid), comprehensive score of symptoms, item scores of the symptoms, and Karnofsky Performance Status (KPS) score were changed significantly after treatment (P<0.01).Conclusion Acupuncture is an effective method in treating MPE of moderate volume, and it can swiftly improve the symptoms and promote the quality of life.
