Objective: To analyze the equity of benefit for inpatient services under the three basic medical insurance programs in China.Methods: Using the baseline survey data collected by China Family Panel Studies (CFPS) in 2010, and the two-part model was applied to explore whether the insured groups with different income levels had different aspects on inpatient rate and the compensation of hospitalization expenses in health insurance coverage.Results: There was no significant difference in the inpatient service utilization rate for different income groups, but the highest and second highest income groups reimburse more expenses than the lowest income group, that is 36.5% and 26.3%, respectively.Specifically, the income level and the compensation amount are not significantly correlated in the Urban Employer Medical Insurance (UEMI) program;the compensation amounts to be paid by urban residents are basically increasing with the increase of the income level;and there is a moderate discrepancy between the highest and the lowest income groups in the New Rural Cooperative Medical System (NCMS).Conclusion: The benefit equity is obviously fair in terms of inpatient service utilization rate, but the benefit degree increases for higher income groups, which shows that there are unfair inequalities related to the income at the level of reimbursement.In terms of program comparison, the benefit degree equity is higher for the UEMI program, followed by the URMI program and the NCMS program is the worst.Besides, the impatient rate and reimbursement amounts are significantly lower for NCMS program participants.The government should merge URMI and NCMS programs, actively promote the integration of basic medical insurance system by strengthening the construction of the medical assistance system and improving the system of catastrophic disease medical expenditure insurance in order to achieve better benefit equity.

Objective:To observe the clinically curative effects of Qingwen Baidu drink(清瘟败毒饮) on epidemic hemorrhagic fever (EHF).Methods:One hundred and eighty cases with EHF who were admitted to hospital within 5 days after onset were randomly divided into two groups.The control group (n=60) was treated with Ribavirin infused intravenously and liquid therapy,and treating complications simultaneously,meanwhile the treated group (n=120) based on the same therapy as control group treated with Qingwen Baidu drink number Ⅰ,Ⅱ or Ⅲtaken orally two times a day according to different course.Results:In treated group all the days of fever,polyuria,recovering platelet to normal,and transforming proteinuria to negative were significantly shorter than those in control group (both P<0.01),otherwise the overphase rates of oliguria and hypotension shock were higher than those in control group too (all P<0.01).The occurance rate of complications in treated group was lower than that in control group(P<0.05).Conclusions:The curative effects adding Qingwen Baidu drink on EHF are significant and worth spreading.

Objective:To investigate the roles and regulation mechanism of miR-31 in human cutaneous squamous cell carcino-ma (cSCC) growth. Methods:cSCC cells were transfected with the antisense oligonucleotide (ASO) of miR-31, and the cSCC growth was tested by colony formation and in vivo tumor formation assays. The target gene of miR-31 was validated by Western blot and green fluorescent protein (GFP) reporter assay. The cells were then transfected with the siRNA of the target gene, and the effect of the target gene on cell growth was preformed by colony formation assay. Finally, real-time PCR and immunohistochemistry were used for analy-sis of the expression of miR-31 and its target gene. Results:miR-31 ASO resulted in a low number of cell colonies and small tumor vol-ume (P<0.05). Western blot showed that the cells with miR-31 ASO had a higher protein level of large tumor suppressor homolog 2 (LATS2) than the control. The 3' UTR of LATS2 had a binding site with miR-31, and miR-31 ASO increased the GFP intensity con-trolled by LATS2 3' UTR, whereas no effect was observed on the mutant LATS2 3' UTR. Western blot showed that LATS2 siRNA inhib-ited the expression of LATS2 protein by about 80%. Knocking down of LATS2 increased the colony number by about 70%or 1.3-fold in cSCC cells. Real-time PCR showed that miR-31 was overexpressed in most cSCC tissues, compared with normal tissues. An inverse relationship existed between miR-31 and LATS2 expression levels. Immunohistochemistry validated that LATS2 was downregulated in cSCC tissues. Conclusion:miR-31, which functions as an oncogene, promotes cSCC growth by suppressing LATS2 expression. Our da-ta suggest that miR-31 is a potential miRNA-based therapeutic target for cSCC growth.

Objective To search for the differences of serum proteins expression in ulcerative colitis (UC) by proteomics method and to preliminary explore the potential biological markers of ulcerative colitis. Method The serum of 30 ulcerative colitis patients and 30 healthy individuals were collected. The equal amounts of proteins in pooled serum were separated by two-dimensional gel electrophoresis (2-DE) and then compared and analyzed by image analysis software to recognize the differences of protein expression. Some spots of proteins with different expression were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).Result There was no statistic significant in age, weight index, smoking and alcohol taking between UC group and control (P ＞ 0.05 respectively). Thirty-nine proteins with significant different expression between UC patients and healthy individuals were preliminary screened out. Nine of those spots were selected, after analyzed by MALDI-TOF-MS, it was found that the expression of haptoglobin, heat shock factor protein 2, receptor tyrosine kinase, aldehyde reductase,apolipoproteinC-Ⅲ, pericentriol material 1 increased in ulcerative colitis patients, keratinl, filamin A interacting protein 1 and tropomyosin 3 decreased. Conclusions With proteomics 2-DE and spectrometry methods, nine UC associated serum proteins were screened out and identified, which provide new molecular markers for the research of UC biological behavior.

ObjectiveTo investigate the protective effect and mechanism of monosialotetrahexosyl gangliosides ( GM-1 ) on neurons after spinal cord injury (SCI) in rats by observing the effect of GM1 on the expression and motor function of microtubule-associated protein 2 (MAP-2) and Choline acetyltransterase (ChAT). MethodsSixty-six adult female Wistar rats (weighing 260-300 g) were enrolled in the study and six were selected randomly as the normal control group. The rest were divided into GM1 group (group A, n =30) and normal saline control group (group B, n =30) after acute contusion injury was made at T10 level according to the improved Allen's method. At days 1,3, 7, 14 and 28 after operation, the neurological function of the low extremities was assessed with the improved Tarlov scale. Then,the rats were sacrificed to obtain the spinal cord tissues. There were six rats in each group at different time points. The expressions of MAP-2 and ChAT were detected with immunohistochemistry after SCI in rats. ResultsThe improved Tarlov scale in the Group A was higher than that in the Group B after SCI since the 7th day after operation, with statistical difference at day 7, 14 and 28 after operation ( P ＜0. 05). The expressions of MAP-2 and ChAT in the Group A were higher than that in the Group B after SCI ( P ＜ 0.05 ). ConclusionsThe neurological function recovery of the low extremities has some correlations with the expressions of MAP-2 and ChAT after SCI in the rats. GM-1 can protect the neurons by promoting the expressions of MAP-2 and ChAT after SCI.

From August 2007 to January 2009 a total of 95 patients with complex renal calculi were treated with CT ( n = 32 ), X-ray ( n = 33 ) or ultrasound ( n = 30 ) guided percutaneous nephrostomy and ureteroscopic holmium laser lithotripsy respectively. The CT guided procedure had lower positioning time,positioning failure rate, complication rate and residual stone rate than those of X-ray and ultrasound localization, particularly had advantages in the stone clearance rate and complications rate ( all P ＜ 0. 05 ).CT guided localization can be chosen in the following conditions: higher kidney position, large staghorn calculi or renal pelvis stones without hydronephrosis, with congenital renal malformations or failure of ultrasound or X-ray localization.

Objective To study the effect of cardiac resynchronization therapy (CRT) on the cardiac function and arrhythmias of patients with chronic heart failure and left ventricular systolic dyssynchrony. Methods Thirty-two cases of patients with chronic heart failure and left ventricular systolic dyssynchrony underwent CRT therapy. And LEVESV, LVEDV, LVEF, LVEDD, MRA, LAA, MRA/LAA were detected by echocardiography while the cardiac function was kept stable. Then the left ventricular systolic 12 segment peak time (Ts) was measurements by tissue doppler in all patients, the poor (Ts-maxD) and standard deviation (Ts-SD) were also calculated. The 24-hour ambulatory 12-lead ECG was took postoperation. All the patients were treated by anti-heart failure drugs after CRT pacemeker implantantion. All these indicators were assessed again at 12 weeks later. Results Compared with the previous CRT pacemaker implantation, LVEF, LV dp/dpsignificantly increased (P < 0.05). LEVESV, Ts-maxD, Ts-SD, MRA, MRA/LAA markedly declined (P < 0.05). But no statistical significance was found between the preoperative and postoperative CRT (P>0.05). Atrial premature beats and paroxysmal atrial tachycardia were significantly reduced in the preoperative CRT (P < 0.05). No significant differences were found in atrial fibrillation, ventricular premature beats and paroxysmal supraventricular tachycardia between the preoperative and postoperative CRT (P > 0.05). Conclusion CRT resynchronization therapy can improve left ventricular systolic function, and reduce the MRA and Ts. The mechanism may be associated with the improvement of left ventricular synchrony, reducing mitral regurgitation, and reducing the occurrence of atrial arrhythmias.
