Based on the basic data of China's total health expenditure from 2003 to 2015, this paper compares and analyze the structural characteristics of total health expenditure financing and the per capita disposable income before and after the new health care reform, in order to understand the overall level of total health expenditure financing before and after the new health care reform, whether the financing structural changes is reasonable and the overall trend is sustainability, and the relationship of the changes between per capita disposable income and health expenditure.The study found that, 1) although the growth rate of total health expenditure in China has declined after the new health care reform, the growth rate of personal health expenditure is still on the rise;2) the growth rate of government health insurance expenditure is limited to the substitution of personal health expenditure, and the growth rate of per capita personal health expenditure is still higher than the growth rate of urban and rural residents' per capita income;3) the problem of residents' serious burden of medical treatment is still very prominent.Based on the above problems, this paper accordingly proposes to speed up the reform of public hospitals, strengthen the construction of medical insurance fund specialization, and improve the ability of medical insurance fund to control costs, etc.

Objective To explore the feasibility of blood oxygen level-dependent (BOLD) MRI to detect the chronic hepatitis b-induced early kidney injury. Methods Seventeen clinically diagnosed chronic hepatitis b patients with early kidney injury and 10 healthy volunteers were enrolled in this preliminary study. The 17 patients underwent dynamic nuclear renography and then subdivided into stage 1 kidney injury group (n=7) and stage 2 kidney injury group (n=10). All of the enrolled subjects underwent BOLD examination and T2* relaxation rates (R2*) of renal cortex and medulla of split kidney, and the ratio between them (R2*med/cor) were measured separately. One-way analysis of variance (ANOVA) were performed on the control group and chronic hepatitis b patients group (kidney injury stage 1 and stage 2 group) to compare the difference of renal cortical and medullary R2*values and R2*med/cor ratio. ROC curves were used to evaluate the efficacy of renal cortical and medullary R2* values and R2*med/cor ratio to diagnose the chronic hepatitis b-induced kidney injury. Results The cortical R2*values of control group, stage 1 kidney injury group and stage 2 kidney injury group were(16.87 ± 0.74)/s,(17.88 ± 0.73)/s,(20.29 ± 2.87)/s, respectively;the medullar R2*values of control group, stage 1 kidney injury group and stage 2 kidney injury group were (28.07±1.03)/s,(31.14±2.49)/s,(32.81±3.28)/s, respectively;R2*med/cor of the of control group, stage 1 kidney injury group and stage 2 kidney injury group were 1.67 ± 0.09, 1.75 ± 0.16, 1.63 ± 0.13, respectively, and the differences among the three groups were statistically significant (F values were 17.779, 19.170 and 3.439 , all P<0.05). Furthermore, the renal cortical and medullary R2* values of chronic hepatitis b patients were significantly higher than the control group, and the the renal cortical R2* value of the patients in stage 2 kidney injury group was also higher than the stage 1 kidney injury group. The area under curve (AUC) of ROC of the renal cortical and medullary R2*values and R2*med/cor to diagnose chronic HBV hepatitis-induced early kidney injury were 0.903, 0.949 and 0.526, respectively. Conclusion It's feasible and has great value to use renal BOLD MRI for the diagnosis of chronic hepatitis b-induced early kidney injury, and the renal cortex is more sensitive than the medulla to the kidney injury.

OBJECTIVE:To excavate and evaluate the security alert signals of linezolid after marketing,and to provide refer-ence for rational drug use in clinic. METHODS:The reporting odds ratio(ROR)method was used to excavate the security alert signals from the adverse drug events(ADE)data in the OpenFDA platform of FDA during second quarter of 2004-2016. The low-er limit of 95%CI >1 was regarded as suggestive of ADE alert signal. RESULTS:A total of 6828534 reports were extracted, among which there were 7224 reports mainly induced by linezolid. Top 10 ADE reports were thrombocytopenia,drug interac-tion,thrombocytopenia,nausea,anaemia,serotonin syndrome,diarrhoea,pyrexia,drug ineffective,vomiting. After the detec-tion of top 200 ADE reports by ROR method,120 signals related to 18 system organ class(SOC)were identified. Top 5 ADE sig-nals in turn by SOC were medical examination,nervous system disorders,blood and lymphatic system disorders,metabolism and nutrition disorders,cardiac disorders. The high risk signals with clinical reference value included 42 cases of optic neuropathy (ROR=56.33),350 cases of serotonin syndrome(ROR=52.86),162 cases of lactic acidosis(ROR=18.30),31 cases of endo-carditis (ROR=15.38),566 cases of thrombocytopenia (ROR=14.29),122 cases of bone marrow failure (ROR=14.20),261 cases of panhematopenia (ROR=11.92),86 cases of disseminated intravascular coagulation (ROR=10.91),58 cases of toxic epidermal necrolysis(ROR=9.06),etc. As for ADE reports,male was slightly higher than female,and the patients in age group of ≥45 reported evidently more compared to younger age group. CONCLUSIONS:By detecting and evaluating alert signals of li-nezolid through OpenFDA platform,we could effectively lay the foundation for further research of pharmacovigilance.

OBJECTIVE:To provide reference for vancomycin-induced neutropenia adverse reactions/adverse events in clinical diagnosis. METHODS:With a case of children with neutropenia treated by long-course and large-dose vancomycin,PubMed and CNKI were retrieved to collect related literature and the literature was analyzed. RESULTS:Neutropenia may be associated with vancomycin,based on causality criterion of adverse reaction in China. CONCLUSIONS:Vancomycin-induced neutropenia in chil-dren is most likely associated with prolonged exposure induced by infusion,vancomycin dosage should be reduced or stopped,and routine blood and plasma concentration should be closely monitored.

Objective To establish and analyze a mouse model of Staphylococcus aureus?induced arthritis ( Staphy?lococcus aureus septic arthritis, SA) , and provide an animal model for arthritis mechanism research and drug development. Methods Mice were immunosuppressed with cyclophosphamide, then intravenously inoculated with Staphylococcus au?reus. The gross characteristics of the joints were observed, the arthritis indexes were analyzed, and the pathological scores of the model mice were evaluated. Results From the first day after bacterial inoculation, the mouse joints were swollen. Pathological examination revealed lesions varying from mild and disarranged joint synovial hyperplasia to synovial thickening and intra?articular invasion, and increased neutrophil infiltration. Conclusions A mouse model of Staphylococcus aureus?induced arthritis is successfully established in this study. This model can be developed in a relatively short time, can not only simulate the clinical symptoms and signs and disease progression of human arthritis, but also to a certain extent reflects the etiology, infection and immunological mechanisms of human arthritis.

Objective The purpose of this study was to establish and evaluate a mouse model of sepsis for studying the mechanism of sepsis and development of anti-inflammatory drugs.Methods The sepsis in mice was induced by cecal ligation and puncture ( CLP) .The survival rates, microbial load, liver and kidney damages, cytokines and pathological changes were detected to evaluate the mouse models.Results The death of mice was closely related with the ligated sites. The mice with 50%cecal ligation displayed about 40% of 12-day survival rate, however, all the mice with 75% cecum ligation died within 4 days (P<0.01).Compared with the sham surgery group, the mice with 50% cecal ligation had a high microbial load in the blood and abdominal cavity.Leukopenia was also emerged (P<0.001).CLP mice demonstra-ted elevated levels of serum ALT, AST and BUN (P<0.01).The levels of IL1α, IL6, IL10, MIP1α, MIP1β, and TNFαwere increased a lot.The liver and lung showed obvious pathological injury at 48 h post CLP.Conclusions The established mouse model of CLP shows typical characteristics of sepsis and is an ideal tool for further study of anti-inflam-matory drugs.

OBJECTIVE:To investigate the general regularity and characteristics of propylthiouracil (PTU)-associated small vasculitis (ASV),and to provide reference for rational drug use in the clinic. METHODS:ADR/ADE case reports of PTU-ASV published during 1990-2016 were retrieved. The data of 118 ADR cases were analyzed statistically. RESULTS:The incidence of PTU-ASV was higher in female and was highest in 18-59 age group. Drug dose of 87 patients were within 600 mg/d,and the inci-dence of PTU-ASV was the highest within 1-5 years after medication. Main clinical manifestations were renal and lung function in-jury. After drug withdrawal,59 patients received hormone therapy,and 30 patients received hormone combined immunosuppressive agent. Finally,115 patients were recovered and 3 patients died. CONCLUSIONS:In older to reduce or avoid the occurrence of ADR,it is necessary to regularly check antineutrophil cytoplasmic antibody related indexes and evaluate the symptoms of ADR.

Objective To explore the functional improvement effect of acupuncture and moxibustion therapy of traditional Chinese medicine(mainly acupuncture on the three yang meridians of the hand,moxibustion on the governor vessel,and moxibustion through drugs)on cervical spondylosis of wind cold blocking collateral type.Methods 120 patients with wind cold obstruction type cervical spondylosis admitted to our hospital from July 2021 to July 2023 were randomly divided into two groups,with 60 cases in each group,using a random number table method.The control group was treated with conventional cervical traction,while the observation group was treated with traditional Chinese medicine acupuncture and moxibustion on the basis of the control group(mainly acupuncture at the hand Sanyang meridian+moxibustion at the governor's meridian+moxibustion through drugs).Compare the TCM syndrome scores,NDI,HO-1,LpPLA2,clinical efficacy,adverse reactions,hospitalization costs,and duration between two groups.Results After 4 weeks of treatment,the effective rate of disease in the observation group with wind cold obstructing cervical spondylosis(96.67%)was higher than that in the control group(83.33%),while the traditional Chinese medicine syndrome score,NDI score,HO-1,LpPLA2 in the observation group were lower than those in the control group(P<0.05).No adverse reactions were observed in both groups.Conclusion Traditional Chinese medicine acupuncture and moxibustion therapy(mainly acupuncture of the three yang meridians of the hand,governor vessel moxibustion,and herbal penetration moxibustion)has significant clinical effect in the application of cervical spondylosis of wind cold blocking collateral type,which can effectively improve clinical symptoms and biochemical indicators,promote the rehabilitation of cervical function,and has high safety.

OBJECTIVE:To provide reference for developing zero-profit drug policy and compensation mechanism better in ur-ban public hospitals. METHODS:Taking a public hospital in a city as an example,effects of zero-profit drug policy on hospitals, patients,health insurance fund and single diseases with different drug proportions [cataract (2.94%) vs. chronic renal failure (38.77%)] were investigated by analyzing the canceled drug addition costs and adjusted medical service price data after developing zero-profit drug policy. RESULTS:After developing zero-profit drug policy,the overall compensation rate in the public hospital was 95.20%. The overall burden of urban patients was reduced,average burden cost was decreased 197.73 yuan every time;while the overall burden of urban and rural residents had increased,average burden cost was increased 17.39 yuan every time;and the overall burden of all patients had decreased. Health insurance fund had decreased,in which,the urban workers were decreased 151185500 yuan,and urban and rural residents were increased 4550400 yuan. In medical insurance for urban workers and health insurance for urban and rural residents,hospital increased by 7.00% and 8.99% in income in the treatment of cataract,the medical insurance fund increased by 12.07% and 13.67%,and patients'burden increased by 0.58% and 3.43%,respectively. For chronic renal failure,hospital income increased by 3.23% and 3.93%,medical insurance fund decreased by 3.19% and 3.96%,and pa-tients'burden decreased by 4.27% and 3.63%,respectively. CONCLUSIONS:Zero-profit drug policy is the ideal measure for get-ting rid of"drug-maintaining-medicine". When developing the policy,it should be combined with actual situation and different dis-eases to explore adjustment of medical service prices,reasonable financial compensation models and medical insurance payment mechanism.

Abstract: This study aims to find out the causes for the dissolution of unqualified samples found during evaluation sampling of lansoprazole enteric-coated preparations by the laser infrared imaging system and orbitrap high resolution mass spectrometry, with suggestions for improvement. Lansoprazole enteric-coated preparations were tested by current standard, the dissolution of a batch of samples was below the limit and other items were in line with the standard. Considering that this product is unstable to acid and alkali, the following exploratory experiments were designed from different dimensions, based on the conclusion of the unannounced inspection of the company, to explore the reasons for the unqualified batch, including the influence of high-temperature and high-humidity storage environment on the key quality properties of the sample, the influence of 2-hour acid resistance test on dissolution result, the imaging of the core and the measure of coating layer thickness, the optimization of chromatographic conditions of related substances, and the analysis of the source of impurities. It was found that improper storage in circulation and poor coating process caused the low dissolution of this batch: the high-temperature and high-humidity storage environment possible in the circulation process led to the decreasing efficacy of disintegrating agent in the samples and thus the difficulty to release the active pharmaceutical ingredient fully; the coating solution could not be uniformly sprayed on the core, resulting in thin isolation layer and different thickness, which then affected the protection of the main drug against acid degradation. The above two reasons together resulted in unqualified dissolution of this batch. The overall quality of lansoprazole enteric-soluble preparation is good, but the formulation and process in some companies need to be optimized; and the temperature and humidity in the circulation process need to be controlled in strict accordance with the regulations.
