Objective To investigate the effects of telmisartan on the blood glucose, blood lipid, blood insulin, and insulin resistance in the hypertensive patients with dyslipidemia, and also its effect on controlling blood pressure. Patients and Methods A total of 96hypertensive patients (34 females, 62 males) with dyslipidemia were included (mean age 51.2±9.6, range 42-65 years). Patients were randomized to receive either telmisartan 80 mg/day (n=46) or enalapril 10 mg/day (n=50) for 6 months. The levels of blood pressure (BP), heart rate (HR), and biochemical data were measured before therapy and at the end of the 3-month treatment and 6-month treatment, respectively. Meanwhile, insulin resistance was evaluated by using a homeostasis model assessment of insulin resistance (HOMA-IR) and insulin sensitivity (HOMA-IS). Results In the telmisartan group, the mean blood pressure was obviously lower than that of pre-therapy (P＜0.05), and the levels of triglyceride (TG), HOMA-IR, and HOMA-IS were all obviously lower than those of pre-therapy and of the enalapril group at the end of the 3-month-treatment period (P＜0.05). After 6 months of treatment, the levels of TG, HOMA-IR, and HOMA-IS in the telmisartan group were significantly lower in comparison with those of pre-therapy, the enalapril group (P＜0.01), and 3-month-treatment (P＜0.05). Post-prandial12 hour blood glucose (P2HBG) in the telmisartan group decreased significantly after 6-month treatment compared with that of pre-therapy and the enalapril group (P＜0.05). The level of high density lipoprotein (HDL) cholesterol was significantly higher after 6-month treatment in the telmisartan group than with pre-therapy and the enalapril group(P＜0.05). Conclusions Telmisartan could not only control blood pressure steadily and effectively, but also decrease blood TG, increase HDL cholesterol and insulin sensitivity, and lower insulin resistance.

Objective To explore the relationship and influencing factors between pre‐diabetes mellitus (pre‐DM) and hypertension, providing evidence for formulating strategies for cardiovascular disease prevention and control. Methods We conducted this study from June 2013 to September 2014. Using stratified multistage random sampling, participants were administered a questionnaire survey, their height, weight, waist circumference, hip circumference, other physical attributes, blood pressure and blood lipids were measured. They also underwent the 75‐g glucose tolerance test and other laboratory examinations. A logistic regression model was used to analyze the relationship between pre‐DM and hypertension and its influencing factors. Results A total of 4 002 participants completed the survey. Participants'mean age was 50.3 ± 11.8 years. Of the total participants, 1 962 (49.0%) were males, while 2 039 (51.0%) were females; 1 participant had missing gender data. Further, 2 188 participants had normal glucose metabolism, 1 066 had pre‐DM, and 748 had diabetes. The prevalence of hypertension in participants with normal glucose metabolism, impaired fasting glucose, impaired glucose tolerance, both impaired fasting glucose and impaired glucose tolerance, and DM was 28.3%, 46.5%, 46.3%, 62.0%, and 61.2%, respectively. The prevalence of hypertension varied among people with different glucose metabolism (χ2=306.672, P<0.001). The prevalence of hypertension in the pre‐DM population increased with the aggravation of abnormal glucose metabolism compared to the normal glucose metabolism population, with a linear trend (χ2=299.009, P<0.001). Among those with abnormal glucose metabolism, there were differences in age, cholesterol, triglycerides, low‐density lipoproteins, body mass index, and waist circumference compared to those without hypertension (P<0.05). The risk of hypertension in the pre‐diabetic population was 1.5 times higher than that in the normal glucose metabolism population (OR=2.510, 95% CI: 2.156-2.922, P<0.001). There was no difference in the correlation intensity between pre‐DM and hypertension when gender was taken into account. Age and lipid abnormalities slightly decreased the correlation intensity between abnormal glucose metabolism and hypertension. Considering body mass index and centripetal obesity, the correlation intensity between abnormal glucose metabolism and hypertension could be reduced by controlling these factors. Conclusion The prevalence of hypertension is high in people with pre‐DM. There is a correlation between pre‐DM and hypertension, even when considering factors such as age, dyslipidemia, body mass index, and centripetal obesity. Therefore, it is necessary to strengthen the management of blood pressure in the pre‐diabetic population; improve early intervention for risk factors such as dyslipidemia, body mass index, and centripetal obesity; and reduce the occurrence of hypertension.

Objective:To investigate the iodine nutritional status of children in Qingdao City and the effects of prevention and treatment measures on iodine deficiency disorders (IDD), and to provide a scientific basis for guiding residents to scientifically supplement iodine, taking timely targeted prevention and control measures, and scientifically adjusting intervention strategies.Methods:According to "National Iodine Deficiency Disorders Surveillance Program (2016 edition)" and "Iodine Deficiency Disorders Surveillance Program of Shandong Province", from 2018 to 2020, using the cluster sampling method, children aged 8-10 years in Qingdao City were chosen to test their household salt iodine content and random urinary iodine content, and to examine their thyroid volume by B-ultrasonography, and the correlation between thyroid volume and physical development indexes was analyzed.Results:From 2018 to 2020, a total of 6 057 children were monitored, including 3 068 boys and 2 989 girls. The median of salt iodine and iodized salt iodine of children was 23.50 and 24.10 mg/kg. The qualified rate of iodized salt was 89.95% (4 832/5 372), the coverage rate of iodized salt was 88.69% (5 372/6 057), and the consumption rate of qualified iodized salt was 79.78% (4 832/6 057). There were significant differences in the qualified rate of iodized salt, the coverage rate of iodized salt and the consumption rate of qualified iodized salt between different years (χ 2 = 135.26, 314.71, 342.87, P < 0.001). A total of 6 057 urine samples were collected from children, and the median of urinary iodine was 193.92 μg/L, of which 16.2% (979/6 057) were < 100 μg/L, and 22.5% (1 361/6 057) were ≥300 μg/L. There were statistically significant differences in the medians of urinary iodine between different years, gender and whether eating iodized salt ( H/Z = 37.25,-3.89,-5.69, P < 0.001), the median of urinary iodine in boys was higher than that of girls, and the median of urinary iodine in eating iodized salt group was higher than that of eating non-iodized salt group. There was no significant difference in the median of urinary iodine between different age ( H = 4.33, P = 0.119). The rate of goiter in children was 3.45% (71/2 057), and the difference between different years was statistically significant (χ 2 = 42.68, P < 0.001). The incidence of goiter in 2020 [7.31% (45/616)] was significantly higher than that in 2018 and 2019 [2.81% (18/641), 1.00% (8/800), P < 0.001]. Thyroid volume of children was positively correlated with height and weight ( r = 0.20, 0.22, P < 0.001). Conclusions:The iodine nutritional level of children aged 8-10 years in Qingdao City is appropriate. However, the incidence of goiter in children in some years is relatively high. The qualified rate of iodized salt, the coverage rate of iodized salt and the consumption rate of qualified iodized salt are all lower than the national standard for elimination of IDD, which should be paid attention to.

Objective:To explore the optimal evidence for the nursing management of limb spasm in patients with spinal cord injury.Methods:Based on the "6S" evidence model, the databases including CNKI, Wanfang, PubMed and Cochrane Library, the guideline websites such as the National Guideline Clearinghouse, Guidelines International Network and Registered Nurses′ Association of Ontario, and the websites of professional associations such as the Royal College of Physicians, American Spinal Injury Association and Canadian Spine Association were systematically searched. Search period of each database was set from the year of inception until July 2022. Two investigators independently screened the literatures related to the management of limb spasm in patients with spinal cord injury, and conducted quality evaluation and evidence recommendation level evaluation.Results:Totally 17 literatures consisting of 6 guidelines, 3 expert consensuses, 5 systematic reviews, 2 evidence summaries, and 1 clinical decision were included. Moreover, 30 pieces of evidence were summarized from 3 aspects, including evaluation and identification, drug therapy (chemical denervation, and oral medication), rehabilitation training (hydrotherapy, electrical stimulation, magnetic stimulation, vibration therapy, heat and cold therapy, body position, and exercise therapy).Conclusion:Nursing staff can set up a multidisciplinary team according to the clinical environment and take into consideration of the characteristics of spinal cord injury patients to provide personalized interventions involving evaluation and identification, drug therapy, rehabilitation training, etc., so as to alleviate the degree of limb spasm.

Objective:To assess the operation and usage conditions of all water improvement projects in Qingdao, master the water fluoride content and the prevalence of dental fluorosis in children in drinking-water-borne endemic fluorosis villages, evaluate the prevention and control effect of water improvement project.Methods:From April to October in 2020, all drinking-water-borne endemic fluorosis villages in 7 cities (districts) of Qingdao were selected to investigate the operation and usage conditions of water improvement project, water fluoride and prevalence of dental fluorosis of 8 to 12 years old children. The prevention and control effect of water improvement project on drinking-water-borne endemic fluorosis in Qingdao was evaluated according to the control contents and criteria of drinking-water-borne endemic fluorosis.Results:There were 1 146 drinking-water-borne endemic fluorosis villages, the water improved rate of villages was 100.00% (1 146/1 146), the rate of normal operation of water improvement project was 99.91% (1 145/1 146). There were 1 130 villages with qualified water fluoride and the qualified rate was 98.60% (1 130/1 146). A total of 23 473 children aged 8 - 12 years old were examined, and 631 children were detected with dental fluorosis. The detection rate of dental fluorosis was 2.69% (631/23 473), the dental fluorosis index was 0.048, and the prevalence was negative. The detection rate of dental fluorosis of children in villages with excessive water fluoride (7.03%, 40/569) was higher than that in villages with qualified water fluoride (2.58%, 591/22 904, χ 2 = 41.235, P < 0.01). Conclusion:The operation and usage conditions of water improvement projects in 7 drinking- water-borne endemic fluorosis cities (districts) in Qingdao are good, and the detection rate of dental fluorosis in children is low, which has reached the national control standard.

Objective:To understand the current status of nurses' awareness and needs for the Employee Assistance Program (EAP), as to provide basis for the hospital to formulate EAP.Methods:Using the purpose sampling method, 352 ICU nurses from the Nanjing Drum Tower Hospital Affiliated of Nanjing University Medical School were selected as the research subjects from December 2019 to January 2020. Finally, 350 valid questionnaires were obtained. Use the EAP demand questionnaire to investigate the ICU nurses' awareness and demand for EAP.Results:Among the 350 nurses in the intensive unit, 214 cases (61.14%) had never understood EAP, only 8 (2.29%) had understood and experienced the EAP, and 332 cases (94.86%) believed that the hospital′s implementation of EAP was a benefit provided to nurses. The top two service requirements were: "Relief of work pressure" and "mental health consultation", and hope to receive mixed-mode EAP services; in ICU and CCU, nurses hope EAP can help resolve work-family conflicts; in EICU, they need to provide Specific job skills training services.Conclusions:ICU nurses have insufficient cognition of EAP and urgently need to obtain EAP implementation knowledge; at the same time, it is necessary to formulate an implementation plan that meets ICU nurses′ needs for EAP, that is, to relieve work pressure and carry out psychological counseling to ensure that EAP is launch successfully in ICU nurses.

Objective:To learn the application of nosocomial infection prevention and control measures as stipulated in COVID-19 emergency plans by medical institutions at all levels in the region, for the purpose of strengthening epidemic prevention and control.Methods:During March 12-13, 2020, customized questionnaires were used to learn from 186 hospitals and medical institutions regarding the basics of their nosocomial prevention management departments, emergency plan application and revisions made. Comparison of the ratios or constituent ratios were tested with χ2 test, while the continuous variables analysis between groups was verified with one-way ANOVA. Results:77.53% of the medical institutions had set up independent nosocomial infection management departments, and 87.30% of the institutions were qualified. 80% of the medical institutions had in place emergency plans for respiratory infectious diseases, but 98.05% of them had revised their plans during the pandemic, with an average of 10.85 newly added and revised provisions. Only 30.11% of emergency planed provide for clearly graded early warning.Conclusions:Efforts should be upgraded to develop an emergency prevention and control system for infection prevention and control in epidemics, and improve technical support for infection prevention and control in the system; to strengthen the clearly-graded early warning and graded responses in a scientific manner; and conduct regular drills, revise plan to ensure its applicability.

Objective:To evaluate the effect of prevention and control measures to drinking-water-borne endemic fluorosis in Qingdao, and to provide scientific basis for formulating prevention and control strategies.Methods:From 2019 to 2021, a full coverage surveillance was carried out in 1 146 villages in 7 drinking-water-borne endemic fluorosis areas in Qingdao, including the operation status of the water improvement and fluoride reduction project, the water fluoride content in the villages, and the prevalence of dental fluorosis among children aged 8-12 years.Results:From 2019 to 2021, all the 1 146 affected villages in Qingdao had improved their water supply, and the rates of water fluoride exceeding the standard were 7.16% (82/1 146), 1.40% (16/1 146) and 3.84% (44/1 146), respectively, and the differences between years were statistically significant (χ 2 = 48.36, P < 0.001). The detection rates of dental fluorosis in children aged 8-12 years were 3.11% (803/25 856), 2.68% (629/23 460) and 3.00% (655/21 846), respectively, and the differences between years were statistically significant (χ 2 = 8.26, P = 0.016). The detection rate of dental fluorosis among children in villages with qualified water fluoride (2.85%, 1 986/69 565) was lower than that in villages with excessive water fluoride (6.32%, 101/1 597), with a statistically significant difference (χ 2 = 67.74, P < 0.001). Conclusions:From 2019 to 2021, the effect of prevention and control measures to drinking-water-borne endemic fluorosis in Qingdao is significant and the detection rate of dental fluorosis in children is low, the detection rate of dental fluorosis in villages with qualified water fluoride is significantly lower than that in villages with excessive water fluoride. In the future, we should continue to strengthen water fluoride monitoring and engineering maintenance to ensure that the water fluoride content continues to be qualified and effectively reduce the harm of fluorosis.

Respiratory diseases are common， frequently-occurring clinical diseases. As the prevalence rate is increasing year by year， they have become a problem that seriously affects public health. The diseases are mainly located in the lung by traditional Chinese medicine （TCM） syndrome differentiation. Lung governs Qi and controls breathing and is also an organ for the storage of phlegm. Clinically， phlegm and Qi are often used for the treatment. Banxia Houputang （BHT）， originated from Synopsis of the Golden Chamber （《金匮要略》）， was used to treat plum-stone Ai （globus hystericus） at first. It is composed of Rhizoma Pinelliae， Cortex Magnoliae Offcinalis， Poria， Rhizoma Zingiberis Recens， and Folium Perillae， and treats diseases with the core pathogensis of mutual obstruction of phlegm and Qi. BHT has the effects of moving Qi， dissipating mass， descending adverse Qi， and resolving phlegm， which basically correspond to the pathological characteristics of the lungs. Clinical studies have confirmed that modified BHT can be used either alone or in combination with western medicine to treat chronic pharyngitis， asthma， chronic obstructive pulmonary disease， pneumonia， obstructive sleep apnea， upper airway cough syndrome and other respiratory diseases， with significant effects. It effectively improves the symptoms and signs of the diseases and reduces the recurrence rate. Basic research has shown that BHT plays anti-inflammatory， anti-oxidative stress， anti-apoptotic， autophagy-regulating， and iron overload-regulating roles by regulating the targets in multiple pathways. This paper， by combing the relevant literature in recent years， conducted a systematic review on BHT from the three aspects of syndrome analysis， clinical treatment research and mechanism research， with a view to providing theoretical basis and reference for the mechanism research of BHT in treating respiratory diseases and for expanding its clinical application.
