This thesis, with a Class 3A hospital as the research object, aims at analyzing the status quo and causes of its costs of health materials so as to put forward corresponding methods and suggestions of cost management, thus providing scientific guidance on reducing operating costs and improve medical quality in public hospitals.

Objective:To observe the effects of sonicated extract of Porphyromonas endodontalis(P.endodontalis)on the cell cy-cle and apoptosis of human osteoblastic hFOB 1 .1 9 cells.Methods:hFOB 1 .1 9 cells were treated with sonicated extract of P.end-odontalis at 0 (the control),1 ,1 0 and 1 00 μg/ml for 1 2,24 and 48 h respectively.MTT assay was used to examine cell prolifera-tion.The cell cycle distribution and apoptosis were examined by flow cytometry.Results:The sonicated exact of P.endodontalis in-hibited the proliferation of hFOB 1 .1 9 cells in a time-and dose-dependent manner.24 h treatment of 1 0 μg/ml and 1 00 μg/ml ex-act arrested the cell cycle of the cells in G1 phase,48 h treatment induced apoptosis in a dose-dependent manner.Conclusion:Sonicated exact of P.endodontalis may arrest hFOB 1 .1 9 cells in G1 phase and induce cell apoptosis,leading to inhibition of the cell proliferation.

Objective To compare the cost-effectiveness and cost-utility of venlafaxine and mirtazapine in patients with treatment-resistant major depression (TRD).Methods One hundred and five patients with TRD were enrolled in this study and grouped into venlafaxine treatment (n=50) and mirtazapine treatment (n=55) based on the double-blind randomization scheme generated by computer.The treatment costs of antidepressants during 8 weeks were calculated,the rates of clinical response and remission were taken as treatment effectiveness,and the quality-adjusted life years (QALYs) as treatment utility.The descriptive analysis and nonparametric test were used to compare the cost-effectiveness and cost-utility of different groups.Results During 8 weeks,the treatment cost of antidepressant was ￥ 1 396.44 for venlafaxine and ￥ 1 206.90 mirtazapine,and the difference between two groups was ￥ 189.54.The cost-effectiveness ratios between venlafaxine and mirtazapine were very close (differed ￥ 0.06 for remission rate and ￥ 1.08 for response rate respectively).There was no significant difference for cost-utility ratios between two groups (physical functioning Z=-0.15,P＞0.05 ; mental health Z=-0.54,P＞0.05).Conclusion Both cost-effectiveness and cost-utility of venlafaxine in patients with TRD are close between venlafaxine and mirtazapine.

Objective:Previous studies suggested that the-308G/A allele in the tumor necrosis factor-α(TNF-α) gene promoter (-308G/A) may be a potential risk factor for inflammatory diseases and tumor progression. However, only a few studies have focused on the-308 polymorphism of TNF-αgene with primary lung cancer in Chinese population. This study aims to evaluate the role of TNF-α-308G/A single nucleotide polymorphism (SNP) and the risk of primary lung cancer in Chinese population. Methods:A total of 250 patients and 447 healthy individuals (control group) were involved in this study. Genotyping was performed using TaqMan technology. Results:The frequencies of (GG), (A/G), and (A/G+AA) genotypes of-308G/A SNP in TNF-αgene were 183 (73.2%), 67 (26.8%), and 67 (26.8%) in the patients, and 406 (90.8%), 39 (8.7%), and 41 (9.2%) in the control group, respectively. The distribution of poly-morphism frequencies in the case group and the control group showed a statistically significant difference for the Chinese population (P<0.05). Conclusion:Results indicated that TNF-αgene polymorphism at position-308G/A is associated with susceptibility to lung cancer in Chinese Han population.

A new approach is put forward for reducing the number of trials required for the extraction of the brain event related potentials (ERPs). The approach is developed by combining both the subspace methods and lift wavelet transform. First, the signal subspace is estimated by applying the singular value decomposition (SVD) to an enhanced version of the raw data obtained by orthonormal projection of the raw data onto the estimated signal subspace. At the same time, the colored noise is whitened. Next, the ERPs are extracted by lift wavelet construction of the enhanced version. Simulation results show that combination of both the subspace methods provides much better capability than does each of them. The experiments showed that the practical results were good.

Objective To study the diagnostic value of combined detection of serum CEA,CA199,CA125,AFP and fecal occult blood(FOB) in Dukes B stage colon carcinoma.Methods The above indicators in 56 patients with colon carcinoma (colon carcinoma group),35 patients with colonic polyp benign disease and 41 healthy individuals undergoing physical examination were measured.Then the sensitivity,and specificity of single index detection and their combined detection were analyzed.Results The levels and positive rates of CEA,CA199,CA125 and FOB in the colon cancer group were significantly higher than those in the colonic polyp group and healthy control group (P＜0.05),but the AFP level and positive rate had no statistical difference compared with the colonic polyp group.Serum CEA,CA125,CA199 and FOB were selected into the Logistic regression equation.The corresponding areas under the curve (AUC) were 0.745,0.886,0.792 and 0.864 respectively;the positive detection rates were 48.2 ％,35.7 ％,39.3 ％ and 78.6 ％ respectively.The combined detection could increased the specificity,sensitivity and AUC to 87.5 ％,92.1％ and 0.957,which were more superior to that in the single index detection.Conclusion The combined detection of serum CEA,CA199,CA 125 and FOB can provide the powerful basis for early diagnosing colonic cancer.

Objective To investigate the effects of acupoint therapy on inflammatory factors and its clini-cal efficacy in relieving bronchial asthma. Methods Selected patients with bronchial asthma which was in remis-sion were randomly divided into a treatment group that was treated with acupoint therapy and a control group that was given Seretide. Each group had 30 cases. The treatment period was 4 weeks. Both groups were evaluated in terms of Asthma Control Test ( ACT) scores and the serum content of interleukin-5 ( IL-5) and interleukin-10 ( IL-10) before and at one month ( short-term) , as well as three months after the end of the treatment ( long-term) . The asthma control situation ( fully controlled, partially controlled or uncontrolled) was evaluated. Results Before treatment the average ACT scores of the two groups were not significantly different. After the treatment both the short-term and long-term average ACT scores of the treatment group were significantly higher than those of the con-trol group. The total effectiveness rate of asthma control in the treatment group in the short term ( 93%) was signifi-cantly higher than that in the control group ( 70%) . After the treatment the IL-5 and IL-10 levels in the treatment group were improved to a significantly greater extent than those in the control group. Conclusion Acupoint thera-py can reduce airway inflammation, control bronchial asthma symptoms and show good clinical efficacy, probably by regulating IL-5 and IL-10 levels.

OBJECTIVE:To study the effects of Tanshinone capsules on glucose and lipid metabolism and serum sex hormone level in rats with polycystic ovary syndrome (PCOS). METHODS:90 female SD rats were randomly divided into normal group (distilled water),model group (distilled water),positive control group (metformin 200 mg/kg) and Tanshinone capsules low-dose,medium-dose and high-dose groups(30,60,90 mg/kg),with 15 rats in each group. Those groups were induced PCOS mod-el except for normal group;after modeling,those groups were given relevant medicine intragastrically for consecutive 28 d,once a day. The ovulation rate was compared before intervention and 28 d after intervention. Body weight,fat wet weight,fasting insulin (FINS),fasting blood-glucose (FPG),AUC of glucose,HOMA-IR,ISI,serum levels of FSH,LH and T were detected. RE-SULTS:Compared with normal group,anovulation,body weight,fat wet weight,FINS,FPG,AUC of glucose,HOMA-IR, FSH,LH and T were all increased significantly in model group,while ISI decreased significantly(P<0.05). Compared with mod-el group,ovulation rate and ISI of positive control group and Tanshinone capsules groups were increased significantly after interven-tion, while body weight (except for Tanshinone capsules low-dose group), fat wet weight (except for Tanshinone capsules low-dose group),FINS,FPG,AUC of glucose,HOMA-IR,FSH,LH and T were all decreased significantly(P<0.05),especial-ly in Tanshinone capsules high-dose group and positive control group. CONCLUSIONS:Tanshinone capsules can regulate glucose and lipid metabolism and serum sex hormone secretion disorder in PCOS rats.
