Objective To better understand the relationship between doctors service quality and benefit in township public health centers so as to grasp the priorities of management and reform and promote the healthy development of the health cause. Methods The method of single factor analysis was combined with the method of stepwise logistic regression analysis. Results The study indicates that doctors delivering high quality service on average see more patients per day and contribute more to the business income and that service expenses are lower for patients seeking service from doctors who on average see more patients per day. Conclusion There is a positive correlation between doctors service quality and benefit in township public health centers.

Objective To study the regulatory T cells (Treg-cell) frequencies in patients with childhood acute leukemia and evaluate its clinical application value by investigating the relationship between the increasing numbers of Treg cells and minimal residual disease of leukemia (MRD), Methods Foxp3-FITC/CD25-PE/CD4-PerCP/CD3-APC four-color staining flow cytometry was established to identify Treg cells. Treg cells frequencies both in 10 healthy controls and in 33 patients with newly diagnosed childhood acute leukemia ( B-ALL 17 cases, T-ALL 9 cases, AML 7 cases) were detected. The possibility of the accumulation of Treg cells being the prognostic marker for acute leukemia was evaluated by comparing the results of Treg cells frequency with that of MRD. Results The percentage of Treg cells in CD+4 CD+3 T cells was M = 8. 09% in normal bone marrows, which was significantly different from the results in the bone marrows of newly diagnosed childhood acute leukemia ( M = 12.77% , U = 3.41, P < 0.01 ), but it showed no significantly differences among B-ALL, T-ALL and AML groups. No association was observed between the expression of Treg cells and clinical-biologic characteristics studied. In addition, Treg cells frequency in MRD positive group was significantly different from that in MRD continuously negative group ( M = 14. 74% vs M=11.3%, t =252.5,P<0.05). Conclusions Consistent with results from solid tumor, the study identifies a significantly increased numbers of Treg cells in patients with childhood acute leukemia. The situation of accumulation of Treg cells is closely associated with MRD results during chnical remission. High level of Treg cells may cause poor prognosis and increase the possibility of relapse.

Objective To investigate the effect of lobaplatin combined with irradiation on human nasopharyngeal cancer cell line CNE2,and to illuminate its mechanism of radiosensitization.Methods MTT assay was used to detect the outcome of lobaplatin and irradiation on CNE2 cell proliferation.Clonogenic assay was applied to testify the radiosensitization effect of lobaplatin on the cells.Flow cytometry was used to check the cell cycle distribution and cell apoptosis.Western was used to detect the expression of Bcl-2,Bax and cleaved Caspase-3.Results The proliferation of CNE2 cells was reduced by lobaplatin in a dose-dependent manner.50IC of lobaplatin on CNE2 cells and lobaplatin combined with 4 Gy irradiation was 1.610 μmol/L and 0.077 μmol/L,respectively.The radiosensitization ratio of the combination group was over 3.Within 24 h of drug treatment,the percent of cells in G2/M phase increased with the concentration of lobaplatin.When the concentration of lobaplatin increased to 6 μmol/L,the cells of combination group were arrested at S phase.The apoptosis rate of lobaplatin (5 μmol/L) group,radiotherapy(4 Gy)group and combination group was 15.6%,11.3% and 61.8%,respectively.Western blot showed that the expressions of Bax and cleaved Caspase-3 increased but Bcl-2 decreased in the combination group.Conclusion Lobaplatin could increase radiosensitization of human nasopharyngeal cancer cell line CNE2,probably by depressing Bcl-2 but enhancing Bax expression and hence activating Bcl-2/Bax-Caspase signaling pathway.

The establishment of quality evaluation of traditional Chinese medicine system that not only accords with Chinese medicine function characteristics but also is recognized as international medical circles, is an arduous task in urgent need of solving the current modernization of traditional Chinese medicine in the process of internationalization. It is difficult to evaluate atraditional Chinese medicine by detection of single active components in traditional Chinesemedicinewiththe western medicine quality controlmethod due to the overall effects of traditional Chinese drugs, the components of the overall diversity, targets, and the complexity of the interaction between components of unpredictable make the Long-term since, domestic and foreign scholars continue to explore and put forward a series of quality evaluation of traditional Chinese medicine to promote the development of traditional Chinese medicine. This article summarized the related academic ideas and developments to, providea new thought and perspective for the quality control of traditional Chinese medicine.

Objective To study the level of immunoglobulin and the prevalence of ANA in patients with Graves' diseases(GD).To explore the correlation between GD and other systemic autoimmune disorders.Methods Data of 145 patients with GD and 45 healthy subjects were collected.All cases were detected on the presence of ANA and the level of immunoglobulin,FT3,FT4,and thyroid specific antibodies.Results The presencerate of ANA and the level of IgG in patients with GD were higher than that in healthy controls [(28.28% vs 4.55%);(70.96?26.14 vs 60.41?11.01) mmol/L](P

Objective To establish a desirable quantitative assay system to evaluate the correlation between surgical manipulation and micrometastasis in primary esophageal cancer patients.Methods 118 pe- ripheral blood samples from 40 esophageal cancer patients undergoing radical resection were collected before surgery(B-1),immediately after surgery(B0)and at the third day postoperatively(B+3).Based on real-time quantitative reverse transcription-PCR,carcinoembryonic antigen(CEA)mRNA gene was used in the detec- tion.12 patients with benign tumor and 13 healthy volunteers were collected as negative control groups.Re- sults The median of CEA mRNA copies at B-1,B0 and B+3 were 1592,13 314 and 6221 copies/ml blood, respectively.CEA mRNA expression levels were found to be significantly higher at both B0 and B+3 than that of B-1(P=0.0001 and 0.0209,respectively).No significant difference was found between B0 and B+3(P= 0.4396).Conclusion Surgical manipulation on esophageal cancer patients increases the probability of mi- crometastasis.Therefore,adjuvant therapy is needed during perioperative stage.

Objective To investigate the efficacy,safety and localization of multilayer amniotic membrane transplantation(AMT) for corneal perforation associated with ulceration.Design A retrospective clinical case series.Participants Nine patients(9 eyes)with corneal perforation secondary to ulceration were enrolled into this study.These were little response to medicine,including bacterial keratitis(4 eyes ),fungal keratitis(2 eyes),fungal and bacterial mixed keratitis( 1 eye),virus keratitis( 1 eye),and Mooren's ulcer ( 1 eye).Size of perforation was 0.5~3.0 mm in diameter.Methods The AMT was applied to tamp the perforation,fill the ulcer and cover the surface of ulcer.After surgery,the medicine was continued to be used to treat the original corneal ulcer.The follow-up ranged from 6~20 months.In the suffering eyes,reformation of anterior chamber,healing of ulcer,complications and recurrence of ulceration were observed.Main Outcome Measures Of the postoperative eyes,reformation of anterior chamber,healing of ulcer,complications and recurrence of ulceration.Results The anterior chamber reformed at the first postoperative day in 9 eyes,and kept in normal depth in the follow-up time.At postoperative 2 months,the ulcer healed with sear and a smooth surface.Corneal thickness of the ulcer area recovered almost to normal.During follow up,no recurrence of ulceration or severe complications was noted.Conclusions Multilayer AMT is a safe and effective method for the management of small corneal perforation associated with ulceration,but the ulcer healed with scar.(Ophthalmol CHN,2008,17:101-103)
