Objective To investigate the correlation between the serum ferritin levels and the post-stroke depression (PSD). Methods From July 2014 to October 2015, the inpatients with the first-ever acute ischemic stroke were colected consecutively. Chemiluminescence microparticle immune assay was used to measure the serum ferritin levels within 24 h after admission. Depressive symptoms were screened by using the 17-item Hamilton depression scale (HAMD-17) at 3 months after onset. In patients with a HAMD-17 score ≥7, the depression was further diagnosed according to The Diagnostic and Statistical Manual of Mental Disorders, 4th edition. Results A total of 200 patients with the first-ever acute ischemic stroke were enroled, 55 (27. 5% ) of them were diagnosed as PSD. There were significant differences in the body mass index (BMI), years of education, waist circumference, high sensitive-C-reactive protein, homocysteine, National Institutes of Health Stroke Scale score (at baseline, discharge, and day 90), mRs score (at discharge and day 90), BI (at discharge and day 90), and the proportions of widowed or solitary patients between the PSD group and the non-PSD group (al P < 0. 05 ). The serum ferritin level in the PSD group was significantly higher than that in the non-PSD group ( median [ interquartile range], 261. 90[142. 10-364. 90] μg/L vs. 164. 40[132. 50- 195. 10] μg/L; Z = - 4. 814, P < 0. 001 ). Multivariate logistic regression analysis adjusted for confounding factors showed that the baseline serum ferritin level >136. 375 μg/L was an independent risk factor for PSD (odds ratio 1. 041 per 1-quartile increase, 95%confidence interval 1. 009-1. 239; P = 0. 045). Conclusions The elevated baseline serum ferritin level is associated with PSD.

Objective To investigate MRI manifestations of lumbar and proximal femoral bone marrow changes before and after recombinant human granulocyte colony stimulating factor (rhG-CSF) was subcutaneous injected for healthy adults.Methods Twenty healthy blood stem cell donors without hematologic disease were enrolled in this study. All of them underwent lumbar sagittal and proximal femur coronal MRI examination with spin echo T1 WI and fat-suppressed T2WI.The first examination were performed before subcutaneous injection of rhG-CSF for comparison. In 4-7 days and 30-60 days after injection, the other two examinations were performed. The signal changes of lumbar and proximal femoral bone marrow were investigated by reading pictures and calculating the contrasted noise ratio (CNR).ResultsBefore rhG-CSF injection, all patients presented normal signal intensity of hone marrow. In 4-7 days after injection, all the 20 cases presented homogeneous signal decrease in lumbar vertebral bodys on T1 WI, accompanied by reduced fatty signal. In proximal femur, patchy or stripped hypointensity areas were found in intertrochanteric and subtrochanteric areas on T1 WI. On fat-suppressed T2 WI images, the signal of lumbar and proximal femoral bone marrow changed to equal or slightly-high signal intensity. In all cases,abnormal signal areas presented in lumbar and proximal femoral bone marrow occurred simultaneously in the same case.In the 10 cases received the third MRI during 30-60 days after rhG-CSF injection, signal intensity of lumbar bone marrow turned to normal in all sequence, but abnormal signal intensity areas were still existed and extended to distal part in femoral bone marrow, which appeared as symmetric stripped or patchy equal or slightly-low signal intensity on T1 WI and equal or slightly-high signal intensity on T2 WI. The CNR of lumbar bone marrow to subcutaneous fat before rhG-CSF injection, in 4-7 days and 30-60 days after rhG-CSF injection were 114. 11 ± 15. 11,71.04 ± 12. 25 and 91.64 ± 1 I. 68, respectively. Significant difference was found between before rhG-CSF injection and 4-7 days after injection ( P ＜ 0. 05 ) , but no significant difference between the others( P ＞ 0. 05 ). Conclusion After injection of rhG-CSF, the short-term changes of hematopoietic cells and fat content in bone marrow can be displayed on MRI, which provided non-invasive information for bone marrow transplantation.

Grounded theory was used to summarize and analyze influencing factors and their mechanism on availability of essential medicine.Four factors which influenced the availability of essential medicine were singled out:defective top design in the essential medicine system,interactions among its policies,deviations in the policy implementation by government agencies,and deficiency of supporting policies for the system.The availability of essential medicine in rural areas was influenced by a variety of factors.The ideas and methods of the grounded theory prove helpful for this study.In the future studies,both qualitative and quantitative study should be made to perfect this model formed by the grounded theory,to identify roadblocks and underlying causes in order to provide evidence for improving availability of essential medicine in rural areas.

Objective To analyze the outcomes of the subsidy mechanism reform for China's public hospitals through a financial perspective.Methods An evaluation index system was built using data from China's health (family planning) statistics yearbooks 2009-2016, for comparison of the constituent ratio and chain relative ratio growths of public hospitals in various years.Results Year 2015 found a lower growth rate of medical revenues of these hospitals;year-by-year drop of drug income ratio, yet a gradual rise of income from examinations and materials, and a drop of technical service income growth and its ratio of the total income;a year-by-year drop of drug income surplus growth, and an expanding deficit in medical services;a slower growth of medicine expense growth, with the asset-liability ratio rising to 45.3%, and salary ratio rising to 30.6%.Conclusions The reform on compensating mechanism at public hospitals is demonstrating its impacts on public hospitals, namely slower growth of medical revenue, weakened compensating role of drug income, lower surplus, and higher asset-liability ratio among other financial risk exposure.These hospitals are encouraged to take proactive measures to control costs, including tighter medical service cost control,to secure sufficient and timely government fiscal subsidy, and other funding measures to cope with debts of the hospitals.

Objective To comprehensively evaluate prevention and health care services of community health centers in Shandong province since the ongoing health reform and provide policy basis for development of community health services.Methods To study with rank sum ratio method and important quadrant models.Results Seventy-eight percent of community health centers were appraised as“average”.Overall satisfaction of residents for preventive and health services was 2.66 points.Preventive and health services of community health centers are expected to improve.Conclusion Overall prevention and health services of CHS centers were found less than satisfactory.Prevention and health services of CHS centers in regions a and B were poor,which deserves attention of the government health authorities.The government is expected to take actions to promote development of CHS centers for prevention and health care service.

To investigate the effect of huangqin tang on expression of cytokines and NF-κB p65 in rats with ulcerative colitis (UC), and to probe into its underlying mechanisms of action. The mode of UC rats with cell immunoreactivity was made using compound method (trinitrobenzene sulfonic acid and ethanol). Rats were randomly divided into control group, model group, SASP group and high dose, middle dose and low dose of huangqin tang group. The food intake, body weight and microscopic damage of rats in each group were evaluated after being treated for five days. The blood and colon tissue were also collected. Production of NO was detected by Griess assay, the expression levels of IL-6, TNF-α, PGE2 were detected by ELISA. ICH method was undertaken to determine the expression of NF-κB p65 protein in colon tissue. The food intake and body weight of model group rats were lower than that of control group. The expression levels of NO, IL-6, TNF-α, PGE2 in serum and NF-κB p65 protein of colon tissue in model group were higher than that of control group. The above indexes were ameliorated in high and middle dose of huangqin tang groups. But there was no significant difference with SASP group. NF-κB p65 may be involved in the pathogenesis of UC, and huangqin tang can inhibit the relative activity of NF-κB p65, and decrease the expression levels of NO, IL-6, TNF-α and PGE2.

Objective To investigate a more pedect method for a nice outward appearance of a reconstructed thumb.Methods A free one-stage plasty second toe transfer for thumb reconstruction by interchanging the whole skin-nail flap from the great toe with another one from the second toe.Results There were 12 cases in this group,following-up 6-9 months in 8 cases,7 cases was excellent and 1 cases was good.The reconstructed thumb got a nice looking and more normal function while no blight to the great toe occurred.Conclusion It is an effective new procedure in ameliorating outward appearance of the reconstructed thumb by transferring the free moulded second toe.

Objective:To evaluate the current situation of comprehensive medical and health services of primary medical institutions in a city under the policy of family doctor contracted service, and explore the influencing factors and put forward improvement strategies, for the reference to improve the medical and health service level of primary medical institutions.Methods:In January 2021, 18 primary medical institutions in 3 counties(cities, districts) of a city in Shandong province were selected by stratified sampling method, and 60-70 contracted residents were selected from each institution for questionnaire survey. The questionnaire covered two dimensions: service provision(19 items) and metion frequency of health problems(12 items). According to the principle of information saturation, qualitative interviews were conducted with 20 family doctors and 15 contracted residents to identify the current service needs and existing problems. Descriptive analysis was used for all data, and single factor analysis of variance and multiple linear regression analysis were used for influencing factors of comprehensive service scores of primary medical institutions.Results:1 098 contracted residents were included in this study, and the comprehensive service score was 3.15±0.42. The vaccination, maternal health care and health education scored higher with 3.80±0.54, 3.70±0.64, 3.78±0.57 respectively; The dermatology, mental health counseling and family sickbed scored lower, with 2.27±1.20, 2.97±1.01 and 1.92±1.18 respectively. Contracted institution, gender, age and marital status were the influencing factors of comprehensive service scores( P<0.05). Residents′ needs for family sickbeds, psychological counseling and fall prevention had not been met. Conclusions:The primary medical institutions of the city had provided better basic public health services, while unmet needs were demand for home sickbeds, psychological counseling and fall prevention. We should take effective measures to increase the service supply based on the needs of residents, and provide more comprehensive medical and health services for residents at primary medical institutions.

Objective:To evaluate and analyze the patient experience of residents contracted with primary medical institutions, for providing a basis for improving quality of contracted family doctor services.Methods:Using the Chinese version of the primary care assessment tools(PCAT), a household survey was conducted on 1 400 contracted residents in 9 community health service centers and 9 township health centers in a city from May to June 2020, and their medical experience in primary medical institutions was statistically analyzed. At the same time, interviews were conducted with institutional managers and family doctors. Descriptive statistics and one-way ANOVA were used for data analysis.Results:1 333 valid questionnaires were collected, and the effective recovery rate was 95.2%.The total PCAT scoring was 25.17. Seven dimensions of first contact, continuous, coordination, comprehensiveness, patient and family centered, community-oriented and cultural competence scored in average 3.57, 3.68, 3.54, 3.40, 3.72, 3.67 and 3.59 respectively.372 people(47.1%) had not been referred by the contracted institution before going to the superior hospital or specialized hospital. There were significant differences in the scores of four core dimensions in different types of institutions, age, education level, occupation and income( P<0.001). Conclusions:Given the initial progress of contracted family doctor services in the city, there is still room for improvement. It is suggested to further improve the comprehensiveness, coordinationand accessibility of services, and promote the high-quality development of contracted family doctor services.

Objective: To analyze dermoscopic features of blue nevi. Methods: Clinical and dermoscopic data were collected from patients with confirmed blue nevi in the Department of Dermatology and Venereology, Wuxi People′s Hospital from January 2008 to May 2018, and analyzed retrospectively. Chi-square test was used to analyze differences between groups. Results: Totally, 65 patients with 66 skin lesions were enrolled into this study. A total of 23 skin lesions were subjected to dermoscopy, which showed homogeneous pattern in 20 (87.0%) lesions, pseudo-pigment network pattern in 2 (8.7%) lesions, and cerebriform pattern in 1 (4.3%) lesion, and the homogeneous pattern was more common than the other patterns (χ² = 8.79, P < 0.05) . Under the dermoscope, 10 lesions were monochromatic (43.5%) , 11 were dichromatic (47.8%) , and 2 were multichromatic (8.7%) . Scar-like hypopigmentation was observed in 4 lesions (17.4%) , and vascular structures were observed in 5 (21.7%) , including punctate vessels in 4 (17.4%) and linear irregular vessels in 1 (4.3%) . Papillary hyperplasia was observed in 2 lesions (8.7%) . Additionally, pigmentation around lesions, white streaks, dots/globules, blotches, comedo-like openings were observed in 1 lesion (4.3%) each. Conclusions Blue homogeneous pattern is the most common dermoscopic feature of blue nevi. Pseudo-pigment network pattern, cerebriform pattern, scar-like hypopigmentation, multiple vascular patterns, papillary hyperplasia, white streaks, dots/globules, blotches, comedo-like openings can also be observed in blue nevus lesions.
