ABSTRACT
Objective:To investigate surgical treatment of carotid artery diseases in neck tumor surgery. Methods:A retrospective analysis of the clinical data on carotid artery treatment was conducted in the five cases of neck tumor surgeries treated at Department of Surgical Oncology, the First Peoples Hospital of Lanzhou from March 2010 to May 2020. Surgical methods, including carotid artery resection and ligation, tumor-involved artery resection and vascular reconstruction, and tumor peeling and carotid rupture repairing were used, respectively. Results:Five cases were successfully operated on. One case of carotid artery ligation was followed by intermittent dizziness and decreased contra-lateral limb strength after the surgery. The remaining patients exhibited no neurological complications. A patient with cervical low-grade myofibroblastoma developed into lung metastases 8 months after the surgery. Another patient with cervical lymph node metastases in papillary thyroid cancer developed into lung metastases 24 months after the surgery. Conclusion:Currently, surgical methods for clinical treatment of diseased carotid arteries include carotid artery resection and ligation, simple tumor peeling, tumor invasion artery resection and vascular reconstruction, and interventional therapy. Each surgical method has its own advantages and disadvantages. Therefore, the choice of treatment depends on the patient's specific conditions, physician's clinical experience, and the equipment available.

In recent years, colonic manometry has been gradually introduced into clinical practice. It helps clinicians to gain a better understanding of the physiology and pathophysiology of colonic contractile activity in healthy adults and patients with colonic dysfunction. More and more patterns of colonic motility are being discovered with the help of colonic manometry. However, the clinical significance of these findings still needs to be further investigated. This review enhances our understanding of colonic motility and the current state of development and application of colonic manometry, as well as the limitations, future directions and potential of the technique in assessing the impact of treatment on colonic motility patterns, by analyzing and summarizing the literature related to colonic manometry.

Objective:To study the iodine nutritional status and thyroid function of adult males in iodine nutrition appropriate rural areas of Gansu Province.Methods:In 2017, Liangzhou District and Linze County of Gansu Province with suitable children iodine nutrition were selected as the study areas and 52 males aged 20 - 49 years old were investigated in each study area. One random urine sample was collected to determine urinary iodine. Fasting blood samples were collected to determine serum thyroid-stimulating hormone (TSH), free triiodothyronine (FT 3), free thyroxin (FT 4), thyroglobulin antibody (TgAb) and thyroid microsomal antibody (TMAb). At the same time, thyroid examination was performed by B-ultrasound. Results:The median urinary iodine of adult males in Liangzhou District and Linze County was 180.2 and 161.0 μg/L, respectively, and the difference was statistically significant ( P < 0.05). There was no goiter in adult males in Liangzhou District and Linze County. The serum TSH (median), FT 3 and FT 4 (mean value) of adult males in Liangzhou District and Linze County were 1.85, 1.61 mU/L, 5.19, 5.16 pmol/L and 16.58, 16.30 pmol/L, respectively. There were no significant differences between the two areas ( P > 0.05). The overall abnormal rate of thyroid function in the two areas was 6.7% (7/104), mainly subclinical hypothyroidism (6/7). The incidences of thyroid dysfunction in Liangzhou District and Linze County were 5.8% (3/52) and 7.7% (4/52), respectively, with no statistical difference between the two areas ( P > 0.05). The total positive rate of antibody was 12.5% (13/104). The positive rates of antibody in Liangzhou District and Linze County were 13.5% (7/52) and 11.5% (6/52), respectively, with no statistical difference between the two areas ( P > 0.05). Both TgAb and TMAb were positive in 9/13 of antibody positive persons, of which the proportion of antibody positive persons in Liangzhou District and Linze County were 7/7 and 2/6, respectively. The 11/13 of the total antibody positive persons were simple antibody positive without thyroid hormone and TSH abnormalities. Conclusion:The iodine nutrition of adult males in iodine nutrition appropriate rural areas of Gansu Province is suitable, but there is a potential risk of thyroid disease in this population, which should be paid attention to and checked regularly.

Accumulating evidence demonstrates that the nucleus tractus solitarii (NTS) neurons serve as central respiratory chemoreceptors, but the underlying molecular mechanisms remain undefined. The present study investigated the expression of acid-sensitive ether-à-go-go-gene-like (Elk, Kv12) channels in the NTS of mice. Immunofluorescence staining was used to observe the distribution and cellular localization of the Kv12 channels in NTS neurons. Western blot and quantitative real-time PCR (qPCR) were used to evaluate protein and mRNA expression levels of Kv12 channels. The results showed that all of the three members (Kv12.1, Kv12.2, Kv12.3) of the Kv12 channel family were expressed in NTS neurons, and their expressions were co-localized with paired-like homeobox 2b gene (Phox2b) expression. The expression of Kv12.1 mRNA was the largest, whereas the expression of Kv12.3 was the least in the NTS. The results suggest Kv12 channels are expressed in Phox2b-expressing neurons in the NTS of mice, which provides molecular evidence for pH sensitivity in Phox2b-expressing NTS neurons.

OBJECTIVE@#To summarize and analyze the clinical data and prognosis of the patients with Hürthle cell tumor (HCT) in order to raise the clinicians' awareness of the disease.@*METHODS@#The clinical data on patients with histopathologically proven HCT, without other thyroid carcinomas, were collected retrospectively in Peking University First Hospital from January 2001 to February 2017. All the patients underwent surgery due to thyroid nodules. The follow-up information was also collected.@*RESULTS@#A total of 100 patients were enrolled in the current study. All of them were diagnosed with Hürthle cell adenoma (HCA). There were 77 females and 23 males, with the male-to-female ratio of 1 : 3.3. The average age of these patients was (52±14) years at the time of operation. Fifty-one patients were found their thyroid nodules accidentally by ultrasonography during their health check-ups. 69.4% of the 49 symptomatic patients presented with painless cervical nodules. 83.0% HCA patients were combined with multinodular goiters (MNGs). 88.4% (76/86) patients were euthyroid and 53.8% (21/39) had increasing thyroglobulin levels. The mean longest diameter of HCAs was (3.2±1.5) cm (range: 0.9-7.3 cm) on ultrasonography. There were a series of sonographic features of HCA, such as larger, solidity, hypoecho, a smooth outline, intranodular vascularization, perinodular vascularization, absence of calcification in nodules and absence of enlarged cervical lymph nodes. Compared with the histological diagnosis, the diagnostic accuracy by frozen section (FS) during operation was 97.4%. Twenty-nine patients were followed up with an average period of (49.2±22.1) months and none of them had local recurrence or cervical lymph node metastasis. Six patients accepted thyroid hormone replacement treatment and one had thyrotoxicosis due to over-dose.@*CONCLUSION@#HCA is more common in women. It is often found accidentally by ultrasonography during their health check-ups or presented with painless cervical nodules. It is combined with MNG frequently. HCA exhibits numerous sonographic features but not unique. FS during operation is a reliable method to identify HCA with high diagnostic accuracy. Patients with thyroid hormone administration should be monitored for thyroid function after thyroid surgery.

To establish a prediction model for 6-year incidence risk of chronic kidney disease (CKD) in the elderly aged 65 years and older in China. In this prospective cohort study, we used the data of 3 742 participants collected during 2008/2009-2014 and during 2012-2017/2018 from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey. Two follow up surveys for renal function were successfully conducted for 1 055 participants without CKD in baseline survey. Lasso method was used for the selection of risk factors. The risk prediction model of CKD was established by using Cox proportional hazards regression models and visualized through nomogram tool. Bootstrap method (1 000 resample) was used for internal validation, and the performance of the model was assessed by C-index and calibration curve. The mean age of participants was (80.8±11.4) years. In 4 797 person years of follow up, CKD was found in 262 participants (24.8). Age, BMI, sex, education level, marital status, having retirement pension or insurance, hypertension prevalence, blood uric acid, blood urea nitrogen and total cholesterol levels and estimated glomerular filtration rate in baseline survey were used in the model to predict the 6-year incidence risk of CKD in the elderly. The corrected C-index was 0.766, the calibration curve showed good consistence between predicted probability and observed probability in high risk group, but relatively poor consistence in low risk group. The incidence risk prediction model of CKD established in this study has a good performance, and the nomogram can be used as visualization tool to predict the 6-year risk of CKD in the elderly aged 65 years and older in China.
ABSTRACT
To analyze influencing factors for depressive symptoms in the elderly aged 65 years and older in 8 longevity areas in China. We recruited 2 180 participants aged 65 years and older in 8 longevity areas from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey in 2017. Multivariate logistic regression analysis was performed to evaluate the relationships of socio-demographic characteristics, behavioral lifestyle, chronic disease prevalence, functional status, family and social support with depressive symptoms in the elderly. The detection rate of depression symptoms was 15.0 in the elderly aged 65 years and older in 8 longevity areas of China, and the detection rate of depression symptoms was 11.5 in men and 18.5 in women. Multivariate logistic regression analysis results showed that the detection rate of depressive symptoms was lower in the elderly who had regular physical exercises (=0.44, 95: 0.26-0.74), frequent fish intakes (=0.57, 95: 0.39-0.83), recreational activities (=0.65, 95: 0.44-0.96), social activities (=0.28, 95: 0.11-0.73) and community services (=0.68, 95: 0.50-0.93). The elderly who were lack of sleep (=2.04, 95: 1.49-2.80), had visual impairment (=1.54, 95: 1.08-2.18), had gastrointestinal ulcer (=2.97, 95: 1.53-5.77), had arthritis (=2.63, 95: 1.61-4.32), had higher family expenditure than income (=1.80, 95: 1.17-2.78) and were in poor economic condition (=4.58, 95: 2.48-8.47) had higher detection rate of depressive symptoms. The status of doing physical exercise, fish intake in diet, social activity participation, sleep quality or vision, and the prevalence of gastrointestinal ulcers and arthritis were associated with the detection rate of depressive symptoms in the elderly.
ABSTRACT
To investigate the relationship of sleep duration and sleep quality with anxiety in the elderly aged 60 years and older in China. The elderly aged 60 years and older were selected from the China Short-term Health Effects of Air Pollution Study conducted between July 18, 2017 and February 7, 2018. Multivariate logistic regression models were used to analyze the association of sleep duration and sleep quality with anxiety. A total of 3 897 elderly aged 60 years and older were included in the study. The age of the elderly was (73.4±8.0) years old. Among the elderly surveyed, 6.5 were defined with anxiety, and 18.7 reported poor sleep quality. Multivariate logistic regression models showed shorter sleep duration was the risk factor for anxiety in the elderly that after adjusting for factors such as general demographics, socioeconomic factors, lifestyle, health status, social support and ambient fine particulates exposure. Compared with the elderly with 7 hours of sleep duration daily, the (95) of anxiety for those with sleep duration ≤ 6 hours was 2.09 (1.49-2.93). Compared with those with good sleep quality, the (95) of anxiety for those with poor sleep quality was 5.12 (3.88-6.77). We also found statistically significant correlations of the scores of subscales of Pittsburgh sleep quality index with anxiety, in which the effects of sleep disturbance, subjective sleep quality and daytime dysfunction scores were most obvious, the (95) were 4.63 (3.55-6.04), 2.75 (2.33-3.23) and 2.50 (2.19-2.86), respectively. Subgroup analysis showed that the association of sleep duration and sleep quality with anxiety was more obvious in males and in those aged <80 years. Shorter sleep duration and poor sleep quality are associated with anxiety in the elderly in China.

ABSTRACT
OBJECTIVE@#To compare the genetic architecture of susceptibility variants of IgA nephropathy (IgAN) in Chinese and Europeans.@*METHODS@#We selected the independent genome-wide significant variants of IgAN in European population as candidate variants. Their associations, risk alleles, risk allele frequencies, odds ratios and population attributable risk scores were derived and calculated, then compared with those in the current Chinese population, including 1 194 IgAN patients and 902 controls. Using the significant variants, genetic risk scores were calculated and compared between the East Asians and the Europeans. The correlation between the genetic risk scores and clinical manifestations was also evaluated.@*RESULTS@#There were 16 independent single nucleotide polymorphisms (SNPs) located in 11 loci showing significantly association with susceptibility to IgAN in the Europeans. 93.75% (15/16) of them also showed significant associations in the Chinese (P<0.05). The effects of all the associated SNPs were in the same direction, either risk or being protective for IgAN, between the Chinese and the Europeans. On the contrary, remarkable higher risk allelic odds ratio (P=1.94×10-2), higher risk allele frequency (P=3.09×10-2), and higher population attributable risk (P=3.03×10-4) were observed for most of the associated SNPs in the Chinese than in the Europeans. Furthermore, genetic risk scores were significantly larger in the Asian populations compared with the Europeans (P=1.78×10-163). While there was no significance among the subpopulations in both the East Asians and the Europeans. Compared with the healthy controls, the genetic risk score in the IgAN patients was significantly larger (P=3.60×10-27). Clinical analysis showed the genetic risk score was positively associated with serum levels of IgA and IgA1, phases of chronic kidney disease and Haas grades.@*CONCLUSION@#Our study provides further evidence in the shared genetic architecture between Chinese and Europeans, while differences with respect to the effect sizes and risk allele frequencies across ethnicities, contributing partially to the differences of disease prevalence.

OBJECTIVE: To evaluate the effects of ivabradine in the treatment of heart failure on medical insurance fund budget in China, and to provide support evidence of related economical evaluation for medical insurance department to solve the problem of reimbursement admission of the drug in hospital outpatient department and the establishment of drug list in hospital. METHODS: Excel decision tree model was used. Pharmacoeconomic analysis was conducted based on the data reported in domestic literatures over the years. Firstly, according to the prevalence rate of heart failure in China, the number of patients with heart failure was estimated, which accorded with NYHA cardiac function class Ⅱ-Ⅳ, systolic blood pressure dysfunction and ivabradine indication. Then the cost of ivabradine was estimated. Secondly, the total number of hospitalizations and the cost of hospitalization due to heart failure were estimated. Finally, the cost of ivabredine and the cost of treatment saved by avoiding re-hospitalization due to the use of ivabredine were considered comprehensively. Static budget impact analysis was conducted to evaluate the effects of the use of ivabredine on medical insurance fund budget. RESULTS: The prevalence rate of heart failure in China was raised to 1.3% in 2013. It was estimated that the number of heart failure patients between 35-75 years old in China could be about 8.51 million and total hospitalization times was about 4.32 million per year. The economic burden of hospitalization in heart failure patients was about 168.940 billion yuan in whole country. Since 18% of patients could be avoided re-hospitalization after treatment with ivabradine, the cost of hospitalization could be saved by about 30.410 billion yuan, while the total cost of taking ivabradine was about 17.525 billion yuan. Therefore, the use of ivabradine could save the hidden medical cost budget by about 12.886 billion yuan, which had obvious cost-effectiveness. Static budget impact analysis results showed that by 2019-2020, the expected proportion of patients with heart failure covered by ivabradine would increased to 8.70%, and the total consumption sum would reach about 1.797 billion yuan. The incremental cost savings ratio (ICSR) showed that the cost of hospitalization could be saved by about 11 951 yuan for each additional case of heart failure treated with ivabradine; there could be 5 711 yuan of balance by deducting drug cost 6 240 yuan of ivabradine. CONCLUSIONS: The cost savings of hospitalization treated by ivabradine is not only enough to offset the cost of ivabradine itself, but also has a premium effect. The drug is of certain economy for the treatment of heart failure in China.
ABSTRACT
OBJECTIVE: To investigate the feasibility of multi-payment for drugs for rare diseases and also provide reference for rare disease treatment and the formulation of related policy. METHODS: Taking Gaucher’s disease in Qingdao as an example, the relevant medical insurance policies and drug supply were analyzed; according to the sources of financing, the economic burden of treatment drugs for patients with Gaucher’s disease in Qingdao was estimated. Based on the average total cost of patients with Gaucher’s disease in Qingdao, the drug cost burden of patients with Gaucher’s disease in the whole country was simulated according to the relevant epidemiological survey data, and the problems of medical insurance model for rare diseases in Qingdao were analyzed. RESULTS & CONCLUSIONS: A series of medical insurance policies were formulated in Qingdao. The financing mode of medical insurance includes social funds (from Qingdao Charity Federation, drugs are provided by pharmaceutical manufacturers), medical insurance funds (used for personal self-payment assistance within the scope of medical insurance co-ordination) and civil assistance (used for assistance outside the scope of medical insurance co-ordination). Imidase is currently the only approved specific drug for Gaucher’s disease in China. The designated physician, treatment and drug-taken system is adopted in Qingdao. By the end of 2017, the annual drug consumption of 8 patients in Qingdao was 38-170 bottles, totaling 686 bottles. The annual cost of treatment ranged from 786 600 to 3 519 000 yuan, totaling 1 420 200 yuan. The self-paid expenses ranged from 9 800 to 197 400 yuan (the self-paid ratio ranged from 0.46% to 8.87%), totaling 661 400 yuan. The reimbursement cost by supplementary medical insurance was 509 800 to 1 789 800 yuan (accounting for 54.59% to 65.94%), totaling 8 577 800 yuan. Three patients received civil assistance, the amount of which ranged from 23 100 to 13 000 yuan (accounting for 1.89% to 4.18%), totaling 241 400 yuan. According to the relevant epidemiological survey data (the prevalence rate was 0.15 per 100 000), it is estimated that there are about 2 093 patients with Gaucher’s disease in China. Referring to Qingdao multi-payment model, it is estimated that the total cost of drugs for Gaucher's disease in China is about 3.715 billion yuan, charitable assistance can bear 1.238 billion yuan, while medical insurance expenditure is about 2.255 billion yuan, and individual self-payment is about 222 million yuan. From the point of view of drug cost burden, the multi-payment model in Qingdao has lightened the personal burden of patients’ has achieved significant results. There are problems in Qingdao’s multi-payment model, such as “medical insurance immigration”, low drug accessibility, drug price monopoly, three-level disease prevention needs to be strenghten, etc. The state or provinces and cities can refer to Qingdao model when formulating policies related to rare diseases. Great importance should be paid attention to the existing problems.
ABSTRACT
Obiective Tend to explore the correlation between thyroid function and the severity of coronary artery lesions in chinese coronary heart disease(CHD)patients. Methods A total of 558 patients who underwent coronary angiography at the cardiology department of Peking University First Hospital from January 2013 to June 2015 were enrolled in this retrospective study. All patients were divided into coronary heart disease group and non-coronary heart disease group. Thyroid hormone levels were tested in all patients before angiography,and clinical characteristics,lipid profiles and SYNTAX scores were also obtained. Results Of the 558 patients,409 were diagnosed of CHD(73.3%),and among them,5 patients were hyperthyroid/subclinical hyperthyroid(1.2%),13 patients were hypothyroid/subclinical hypothyroid(3.2%),14 patients had euthyroid sicknesssyndrome(ESS)(3.2%),377 patients were euthyroid(92.2%). Among the 149 non-CHD patients(26.7%),3 patients were subclinical hyperthyroid(2.0%),8 patients were hypothyroid/subclinical hypothyroid(5.4%),2 patients were ESS(1.3%),172 patients were euthyroid(91.3%). The proportion of patients with ESS in the CHD group was significantly higher than that of the non-CHD group (3.4% vs. 1.3%,P=0.018). Except for the patients with ESS,FT3 level was significantly lower the in CHD group than that in the non-CHD group[(4.52±0.57)pmol/L vs.(4.65±0.63)pmol/L,P=0.015]. There were no significant differences in FT4,T3,T4 levels between the two groups(P>0.05). In the CHD group,there was an association between the SYNTAX score groups and free triiodothyronine(FT3)levels(F=6.260,P=0.002). A significant correlation was also observed between the FT3 level and the number of coronary artery lesions(F=5.691, P=0.004). There was no correlation between the SYNTAX score groups or number of coronary artery lesions and thyroid hormone levels,respectively. There were no correlations between lipid profiles and thyroid function. Patients were further divided into three subgroups according to their serum TSH levels. The prevalence of CHD is significantly higher in the subgroup with elevated TSH(85.7%)than in the subgroup with normal TSH(68.6%, P=0.022). Conclusions FT3 level is weakly associated with the severity of CHD. Higher TSH level may be a risk factor of CHD.
ABSTRACT
In the present study, scapaundulin C (1), a new labdane diterpenoid, and four related known compounds scapaundulin A (2), 5α, 8α, 9α-trihydroxy-13E-labden-12-one (3), 5α, 8α-dihydroxy-13E-labden-12-one (4), and (13S)-15-hydroxylabd-8 (17)-en-19-oic acid (5), were isolated from the Chinese liverwort Scapania undulate (L.) Dum., using column chromatography. The structures of these compounds were determined on the basis of 1D- and 2D-NMR analyses. The acetylcholinesterase (AchE) inhibitory activity was evaluated using a bioautographic TLC assay and the cytotoxic activity was evaluated by the MTT method. All the compounds were reported for the first time to exhibit moderate AchE inhibitory activity with minimal inhibitory quantities ranging from 250 to 500 ng. All the compounds were tested for their cytotoxicity against five human tumor cell lines, A549, K562, A2780, Hela, and HT29, and compounds 3 and 4 exhibited moderate inhibitory effects on the growth of A2780 cells.

<p><b>INTRODUCTION</b>This study aimed to describe the demographic, social, developmental and behavioural profile of children hospitalised for alleged child maltreatment syndrome (CMS).</p><p><b>METHODS</b>This study was a retrospective review of the consecutive inpatient records of children (0-16 years) admitted to the National University Hospital, Singapore, for alleged CMS over a three-year period. Descriptive data on the demographic characteristics, alleged maltreatment, medical and developmental histories, and family background of these children were collected and analysed. Chi-square statistics were used to test whether family factors were associated with the type of maltreatment and the presence of developmental disorders.</p><p><b>RESULTS</b>A total of 89 children, who accounted for 90 admission cases, were studied. Physical abuse (70.0%) was the most common, followed by neglect (11.1%) and sexual abuse (7.8%). Child protection services had already been involved in 29.2% of the cases prior to the child's admission. Children who were victims of abuse were more likely to come from homes with a prior history of domestic violence (p = 0.028). Financial difficulty was found to be a risk factor for neglect (p = 0.005). Among the 89 children, 15.7% were found to have developmental disorders and 10.1% had mental health diagnoses. Children who had developmental disorders were more likely to have a parent with a mental health disorder (p = 0.002).</p><p><b>CONCLUSION</b>A sizeable proportion of the children admitted for alleged CMS had developmental or behavioural disorders. Clinicians have a role in ensuring that these children have appropriate follow-up plans. Children from high-risk families should be screened for maltreatment.</p>
