1.Discussion on the Current Payment Status of Public Hospital Medical Insurance
Chinese Health Economics 2013;(9):50-51
Objective: In order to provide references for drawing up related health policy reasonably, the current status of medical insurance payment in third level hospital. Methods: Through analyzing the payment situation of medical insurance in third level hospital from 2010 to 2012, to understand the related situation of gross prepayment system in large publich hospital since this year. Results: In recent years, the coverage rate of health insurance in the whole city is increasing continuously, while the rising extend of annual gross prepayment limit is not obvious, refusal in medical insurance fund is serious and the accounting method of prepay limit is not scientific. Conclusion: While satisfying the quality of patients’ visiting, it needs to implement gross prepay accounting method, enhance medical management and reduce the economic burden of the hospital.

Study on the scientific essence of traditional Chinese medicine (TCM) syndrome is the key in TCM modernization. This paper showed new research ideas for TCM syndrome, which was based on the pediatric adenovirus pneumonia and its TCM treatment, metabonomics and its application in TCM syndrome research, in order to discuss its application value in the diagnosis and treatment of pediatric viral pneumonia. This method was mainly implemented through the metabonomics technology, which reflected TCM holism concept. The syndrome of phlegm-heat obstructing the lung, which was the most frequent syndrome in the pediatric viral pneumonia, was studied. Through the comparison with metabolites of healthy children, the biomarkers of syndrome of phlegm-heat obstructing the lung in pediatric viral pneumonia were identified.

Objective To investigate the effect of swimming exercise on insulin sensitivity and interleukin-1 beta(IL-1β)mRNA expression in muscle tissue of insulin-resistant (IR) rats induced by high-fat diet.Methods The IR rat model was induced by high-fat diet feeding for 10 weeks and assessed by hyperinsulinemic-euglycemic clamp technique (HEC). The rats were divided into the fllowing three groups: normal group without exercise, IR groups with and without swimming exercise. After 4 weeks swimming excersie, insulin sensitivity and serum IL-1β levels were measured.Results Glucose infusion rate (GIR) of the IR rats was significantly elevated than that of non-exercise IR rats (P<0.01). Moreover, serum IL-1β levels were reduced markedly in IR rats (P<0.01). Conclusion High-fat diet feeding can partly reverse IR of rats to normal value. Swimming exercise improves insulin sensitivity and reduces the levels of IL-1β in IR rats induced by high-fat diet.

Objective To study the correlation between psychological state and coping styles of primary caregivers of stroke patients.Method 286 primary caregivers were screened out by the random sampling method for the investigation of their psychological states and coping styles using SCL-90 and the medical coping modes questionnaire(MCMQ).Results There were significant differences between primary caregivers and Chinese norm in terms of all factors(P<0.01).The major caregivers with higher education were scored significantly lower than those with less education on the factors of depression,anxiety,hostility,fear,psychoticism (P<0.01).There were significant different differences between primary caregivers and Chinese norm in coping style(P<0.01): the score on confrontation in the coping style lower than the norm while the score on avoidance in the coping style higher than in norm.The confrontation and avoidance in the primary caregivers were negatively correlated to the factors of SCL-90(P<0.05)and yielding in the coping style positively to the factors of SCL-90(P<0.05).Conclusions The primary caregivers of stroke patients are at the poor psychological states and they tend to take the passive and negative coping styles.The more they take active coping style,the better their mental states grow and vise versa.Therefore,the caregivers need professional training so that they can use the supports from their families and be encouraged to speak out their poor moods.Post-discharge visits to them,besides,are helpful for the improved psychological states for the improvement of their quality of life.

Objective To develop a clinical practice satisfaction scale for the nursing interns,and to test its reliability and validity.Methods Original scale was formed on the basis of literature review and existing clinical practice satisfaction measurement tools of nursing interns.Totally 270 nursing interns of six tertiary first-class hospitals were investigated with the clinical practice satisfacfion scale of nursing intern by convenience sampling.SPSS13.0 and AMOS 17.0 were used to test the reliability and validity.Then the original scale was modified and the eventual scale was formed.Results The Cronbach's Alpha between each entries and the total scale were 0.548~0.752.The Cranbach's Alpha of total scale was 0.965and the split-half reliability of Guttman was 0.885.Five factors were extracted by exploratory factor analysis and they could explain 65.307% of the total variance.The confirmatory factor analysis revealed a good model fit of the first and second order,and the fit indices x2/df,GFI,AGFI,RMR,RMSEA,NFI,CFI,TLI were 1.176/1.095,0.893/0.900,0.856/0.864,0.034/0.033,0.026/0.019,0.918/0.924,0.987/0.993,0.983/0.991.Conclusions The clinical practice satisfaction scale of nursing intern is reliable and valid,and can be used to assess the clinical practice satisfaction of nursing intern.

Objective To study the clinical and genetic features of Lowe syndrome. Methods The clinical data and test results of OCRL gene from two children with Lowe syndrome were analyzed. The related literatures were reviewed. Re-sults Two male patients all presented with low molecular proteinuria, hypercalciuria, rickets and nephrolithiasis. Patient 2 had renal tubular acidosis, glycosuria and cryptochism. Patient 1 was found to have abnormal vision and congenital cataract soon after birth and treated surgically. Patient 1 also had psychomotor retardation and the cranial magnetic resonance ima-ging (MRI) showed agenesis of the corpus callosum. Patient 2 did not have obviously extra-renal symptoms, but was found to have mild cataract by a meticulous ophthalmological examination. MRI showed cerebral hypoplasia and myelination delay and mental retardation was gradually appeared during follow-up. Two OCRL gene mutations were detected. A splice site mutation NG_008638.1:g.46846-46848delTAA/insC was found in patient 1 and a frame shift mutation NM_000276.3:c.321delC in exon 5 was found in patient 2. Both mutations were not reported previously. Conclusions The diagnosis of Lowe syndrome is mainly by clinical manifestations and test of OCRL gene. Lowe syndrome needs to be included in the differential diagnosis of a patient with congenital cataract and renal tubulopathy. Two novel mutations in the OCRL gene were identiifed.

Ultrasonic microbubbles were used to open blood-brain barriers (BBB) with a reversed and limited behavior feature in the study, which could improve the brain-targeted delivery of anti-tumor drugs. The glioma rat model was prepared. Low-frequency ultrasound was combined with microbubbles to affect the permeability of BBB compared with the permeability of independently administered Evans blue (EB) crossing BBB. Time point and length of ultrasound were investigated whether they affect the permeability of BBB and the damage of brain tissue. The effect of the growth time of glioma on BBB permeability was explored. Only glioma had a very little impact on BBB permeability. However, ultrasonic microbubbles opened the BBB with the features of temporary, limited and reversed behavior and improved EB and magnetic resonance imaging contrast agent penetrating BBB. A length of 30 s ultrasound is appropriate for opening BBB and no damage of brain tissue. Drugs should be injected before ultrasound so that they enter into brain as BBB opening. Ultrasonic microbubbles can open BBB effectively and safely, which improve drugs penetrating BBB under proper time point and length.
