Objective To observe the effect of Tongbi Prescription on pathomorphological changes of ankles in adjuvant arthritis rats. Methods Rats were randomly divided into six groups: normal control group,model control group,three Tongbi Prescription treated group (respectively with high-,mid-and low-dosages),Tripterygium glycosides treated group (each n=10). Except for the rats of normal control group,the others were injected with Freund’s complete adjuvant. The pathomorphological changes of ankles of each group were measured. Results The pathomorphological changes of high-and mid-dosages Tongbi Prescription treated group and Tripterygium glycosides treated group were lightened than those of model control group obviously (P

Although private hospitals are generally encountering development difficulties, some private non-profit medical institutions thrived in the medical market. These hospitals have rich experiences in terms of manage-ment system, operation mechanism, and competition methods. In this paper, we summarize the experiences of those well-functioning private non-profit hospitals and analyze the essential conditions for developing private non-profit med-ical institutions. These conditions include meeting local health market needs, ensuring that the hospital management system and operation mechanism result in high-quality health services, ensuring hospital development meets local health plans ( in order to obtain policy support) , ensuring the goal of the hospital is public welfare and that the hospital has strong financial support, obtaining certain social and political capital, and ensuring high-quality managers and staff.

Objective To summarize and discuss the diagnostic and treating experiences of chronic pancreatitis with mass in the head. Methods Eight patients of chronic pancreatitis with mass in the head who were misdiagnosised as carcinoma of head of pancreas were analyzed retrospectively in the past 10 years. Results All the patients exhibited abdominal pain,5 of whom were with jaundice and 3 with anorexia. All the patients were misdiagnosised as carcinoma of head of pancreas before the operation,but the pathology after operation indicated chronic pancreatitis. The pancreaticoduodenectomy was performed in 5 patients,the choledochojejunostomy in 2 patients,while the exploratory laparotomy in 1 patient. After the operations,the abdominal pain was relieved in 7 patients, while 2 patients who accepted pancreatoduodenectomy suffered from pancreatic fistula,1 of whom died in the end. Conclusion It’s hard to differentiate the chronic pancreatitis with mass in the head from the carcinoma of head of pancreas before operation. If the carcinoma of head of pancreas can’t be excluded during the operation,the pancreatoduodenectomy should be performed,while the duodenum-preserving total resection of the head of the pancreas or any intra-drainage operations should be done if chronic inflammation is found in the whole pancreas with a negative result of the biopsy of the pancreas through the needle aspiration.

Objective To survey the value of risperidone in the treatment of depression without psychotic symptoms. Methods 205 depressive patients were randomly divided into 3 groups: risperidone group, fluoxetine group and combined group (risperidone+fluoxetine). They were assessed with Hamilton Depression Scale (HAMD), Treatment Emergent Symptom Scale (TESS) before treatment and in 2nd week, 4th week, 6th week and 8th week after treatment. Results The reduction rate of HAMD of combined group was the best among three groups(P<0.05), and that of fluoxetine group was better than that of risperidone(P<0.01). The significant difference in reduction rate of HAMD between combined group and other two groups was observed since 2nd week after treatment(P<0.05). No difference in scores of TESS has been observed in any time among three groups. Conclusion Risperidone can improve the efficacy of fluoxetine on depression without psychotic symptoms without increasing side effects, but itself is less effective than fluoxetine.

Objective To study the effect of different dialysis modalities on pruritus in elderly maintenance hemodialysis patients.Methods Totally 51 patients were randomly divided into hemoperfusion combined with hemodialysis group (HD+ HP),hemodiafiltration group (HDF) and hemodialysis group (HD).Plasma β2-microglobulin(β2-MG) and intact parathyroid hormone (iPTH) were measured by means of radio immunoassay at pre and post dialysis,4 weeks and 8 weeks after dialysis,cutaneous pruritus was scored.The remission rate of itching was calculated at 8 weeks after dialysis.The parameters were compared among different groups.Results The level of plasma β2-MG was lower in HD+HP group after dialysis than pre dialysis [(13.48±3.05)mg/L vs.(16.27±4.73) mg/L,t＝2.044,P＜0.05],at 4 weeks and 8 weeks after dialysis,its levels were decreased to (10.97±3.25)mg/L(t＝3.808,P＝0.002)and (6.47±2.35)mg/L(t＝7.650,P＝0.000),respectively.The levels of iPTH were also found decrease from(887.5 ± 242.7)ng/L to (688.3 ±223.4)ng/L(t＝3.384,P＝0.004)at 4 weeks and (467.2±102.5) ng/L(t＝6.578,P＝0.000) at 8weeks after dialysis in HD+HP group (all P＜0.01).There were differences of the levels of plasma β2-MG and iPTH at 4 weeks and 8 weeks after dialysis in HDF group (all P＜ 0.05),but no differences of the levels of plasma β2-MG and iPTH during every period were found in HD group(all P＞0.05).The scores of cutaneous pruritus were decreased from (21.17± 5.01) scores to (13.37±2.85) scores(t＝ 5.580,P＝0.000)at 4 weeks and (8.52±4.38) scores(t＝7.838,P＝0.000)at 8 weeks after dialysis in HD+ HP group,and also the scores at 4 and 8 weeks after dialysis in HDF group (all P＜0.01),but there were no significant differences of the scores during every period in HD group (all P＞0.05).The remission rate of itching was better in HD+ HP group than in HDF group [88.24％ (15/17 cases) vs.58.82％ (10/17 cases),x2＝14.44,P＝0.000],better in HDF group than in HD group 23.53％ (4/17 cases) (x2 ＝4.37,P＝0.037).Conclusions HD+HP is superior to HDF in efficiently clear β2-MG and iPTH,and relief cutaneous pruritus,but HD can poorly clear β2-MG and iPTH or relief itching.

The evolution of China’s policy on private medical institutions has been ongoing, and a comprehen-sive policy system has been established. In this paper, we review the development history and summarize the main policy points in terms of planning, approval, financial input, supervision and administration, support and incentives. We analyze current policy barriers from three levels:1 ) policy ideas, consensus on the function and role of private medical institutions have not reached, which may influence the corresponding policy making and implementation;(2) policy design, multiple policy bottlenecks still exist, such as lack of flexibility, poor convergence, vague stand-ards and other aspects; 3 ) policy implementation, the health planning polices and equal treatment polices haven’t been carried out, and there are many hidden obstacles. To solve these problems, we recommend that further attention be paid to the importance of private medical institutions;the running mode should be chosen properly; the develop-ment space should be expanded;the classified management policy should be improved; and the supervision and ex-amination of policy implementation on local governments should be intensified.

0.05). Dysphasia resolved significantly after stent placement in both groups.The improvement of dysphasia was more significant in Group A than in Group B after 2 months of stent placement(1.37?0.56 in group A, 1.82?0.50 in group B,P=0.004).The median survival period was longer in Group A than in Group B (7 months vs 4 months).The mean survival period was also longer in Group A than in Group B (8.3 months vs 3.5 months).There was a statistically significant difference in the survival period between the two groups(P

Objective To investigate the changes of hypoxia-inducible factor(HIF)-1α and hexokinase-Ⅱ(HK-Ⅱ)expression in human esophageal squamous cell carcinoma and its effect in glycolysis.Methods TE13 cells and Eca109 cells were cultured under hypoxic condition(1 ％O2)for different hypoxic time(6,12,24 and 48 hours).Cells cultured under normal oxygen condition(20％O2)were set as control.The changes of HIF-1α and HK-Ⅱ expressions at protein level were detected by Western blot.HIF-1α genes were specifically silenced with RNA interference technology(RNAi),and then the changes of HIF-1α and HK-Ⅱ expression were determined by realtime PCR and Western blot.Under normal oxygen and hypoxic condition,the changes of lactic acid concentration in cell culture medium were detected by spectrophotometric method.Results Under hypoxic condition,the expression of HIF-1α and HK-Ⅱ gradually increased as hypoxic time extended(P＜0.05),reached a peak at 12h and then gradually decreased as time extended.Compared with that under normal oxygen condition,the expression of HK-Ⅱ in TE13 cells and Eca109 cells significantly increased under hypoxic condition(P＜0.05),which was more significant after 12 hours hypoxia.The result of realtime PCR indicated that under normal oxygen condition the expression of HIF-1α at RNA level in TE13/shRNA cells and Eca109/shRNA cells significantly decreased compared with TE13 cells and Eca109 cells without interference(P＜0.05).The expression of HK-Ⅱ at RNA level was consistent with the result of HIF-1α.Under normal and hypoxia condition,the expression of HK-Ⅱ at protein level in TE13/shRNA cells and Eca109/shRNA cells significantly decreased compared with TE13 cells and Eca109 cells without interference,and the difference was statistic significant(P＜0.05).The lactic acid secretion of TE13 cells and Eca109 cells under hypoxia condition(14.707 ± 3.594 and 15.062 ±3.901)was higher than that under normal oxygen condition(6.070±1.839 and 6.891±1.592,P＜0.05).The lactic acid secretion of TE13/shRNA cells and Eca109/shRNA cells significantly decreased compared with TE13 cells and Eca109 cells without interference,and the difference was statistic significant(P＜0.05).Conclusion The expressions of HIF-1α and HK-Ⅱ in human esophageal squamous cell carcinoma significantly increased under hypoxia conditions.The expression of HK-Ⅱ is closely correlated with lactic acid concentration and HIF-1α expression.HIF-1α may affect cell glycolysis through HK-Ⅱ.

Objective To explore the relationship between tumor necrosis factor (TNF) gene polymorphisms in donors and recipients and the incidence and severity of acute graft-versus-host diseases (aGVHD) after unrelated allogeneic hematopoietic stem cell transplantation (alIo-HSCT). Methods Single nucleotide polymorphisms (SNPs) of TNFα-238 (G/A), TNFα-857 (C/T), TNFα-863 (C/A), TNFα-1031 (T/C), TNFβ + 252 (A/G) were analyzed by Multiplex SNaPshot analysis in 76 pairs of donors and recipients. Results Transplantation involving donors with TNFα-857 CC genotype resulted in a higher incidence of grade Ⅱ-Ⅳ aGVHD than donors with CT genotype (91.3% vs 8. 7% , P =0. 039). In the 23 patients with grade Ⅱ-Ⅳ aGVHD, no patients had TNFβ +252 AA genotype, 19 (82.6%) had GA genotype and 4 (17.4%) had GG genotype. There was a significant difference in the distribution pattern of the TNFβ +252 (AA, GA and GG) genotypes in these patients (P =0.03). There was no significant association of TNFα-238 (G/A), TNFα-863 (C/A) and TNFα-1031 (T/C) polymorphisms with the risk of aGVHD. Conclusion These results suggest donor TNFα-857 CC genotype is related to a higher incidence of grade Ⅱ -Ⅳ aGVHD, and patients with TNFβ +252 AA genotype have protection against the risk of grade Ⅱ -Ⅳ aGVHD.
