Hospital business process optimization and reengineering is an effective method and channel for hospitals to enhance medical and management quality, realize cost minimization, improve efficiency, and increase benefits. The paper gives an account of the theories, methods, steps, relevant techniques, and tools of hospital business process optimization and reengineering, discusses the systematic framework for hospital business process improvement and key success factors and obstacles for hospital business process reengineering, analyzes the relationship of business process reengineering with hospital organizational structures and hospital information systems, and puts forward assessment criteria for hospital business process optimization and reengineering.

Objective To analyse the necessity and feasiblity about the diagnosis and classification of fibrocystic disease of breast,through using synthesize imaging methods , to increase the disease ＇s diagnosis rate. Methods Using imaging checks (molybdenum photography,ultrasonography and infra-red scanner) for 600 breast＇s cases and contrast to pathogenesis if they were done operations. Results 143cases were normal,166 cases got other disease of breast,291 cases were fibrocystic disease of breast(48.1%) ,155 cases of them were performed operations and pathogenesis. the diagnosis similar rate between performed operations check and pathogcnesis was 83.2%. Conclusion The sensitivity of three kinds imaging check method is different each other,but one method can give some help each other. The synthesize imaging check can increase the diagnosis rate and avoid mis-diagnosis and doing needless operations.

Objective To discuss the clinical characteristics of diagnosis and treatment of primary gastric malignant lymphoma (PGML). Method The data from 34 PGML medical records were reviewed retrospectively between January 2001 and May 2008. Results There were 23 cases of B-cell malignant lymphoma, 7 cases of T-cell malignant lymphoma, and 4 cases of non-B and non-T small cell lymphoma. Confirmed by pathology, 14 cases of them had metastasis to lymphoid nodes and 5 cases had invaded the organs nearby. All of these 34 cases had gastroendoscopy before operation. Conclusions PGML has no specific manifestation, and the definitely diagnostic rate of gastroendoscopy is low. The surgical resection is the major therapy.Operative pattern,the size of tumor,pathological stage can predicate the prognosis for PGML.

Objective To evaluate the effects of dexmedetomidine on the expression of phosphor-cAMP response element binding protein (p-CREB) in isoloated hippocampal neurons of fetal rats.Methods SpragueDawley rats on 16-18 days of gestation were sacrificed and the fetal rats were obtained.The hippocampi of fetal rats were isolated and hippocampal neurons were seeded in culture medium for 8 days.The cells were then divided into 4 groups (n =12 each) using a random number table:control group (group C),dexmedetomidine 0.001 μmol/L group (group D1),dexmedetomidine 0.010 μmol/L group (group D2),and dexmedetomidine 0.100μmol/L group (group D3).In D1.3 groups,dexmedetomidine with the final concentrations of 0.001 μmol/L,0.010 μmol/L,and 0.100 μmol/L was added to the culture medium,respectively,and then the cells were incubated for 3.5 h.The apoptosis in hippocampal neurons was detected by flow cytometry.The expression of p-CREB in hippocampal neurons was determined by RT-PCR and Western blot.Results Compared with group C,apoptosis rate was significantly decreased and the expression of p-CREB was up-regulated in D1.3 groups.Conclusion Dexmedetomidine inhibits apoptosis in isolated hippocampal neurons of fetal rats by up-regulating the expression of p-CREB.

Objective To study the meaning of breast cancer staging system by AJCC eighth edition to invasive lobular carcinoma and analysis the clinical pathological characteristics.Methods According to the eighth edition of the AJCC staging to evaluate the TNM stage and prognosis evaluation of invasive lobular carcinoma cancer patient in Peking University Shenzhen Hospital from 2011 to 2016,and compared with others in clinical pathological data.Results There were 21 cases of invasive lobular carcinoma,accounting for 2.7％ of all invasive breast cancer.We found that invasive lobular carcinoma shows no significant difference (P ＞ 0.05) in ages,menstrual status,molecular features and anatomic staging and prognosis staging with others;histological grade were significantly different (P ＜ 0.05).There were significant differences in the prognosis and staging of invasive lobular carcinoma.Conclusions Eighth AJCC staging systemn provides a new reference for the clinical treatment of breast cancer,should be evaluated with anatomic stage.Histological grade is relatively good in invasive lobular carcinoma and the prognosis is good,needs more research to the individualized treatment of invasive lobular carcinoma.

Objective To investigate the impact of desmoglein 3 (Dsg3) on the proliferation of peripheral T lymphocytes from patients with pemphigus vulgaris (PV).Methods Peripheral blood mononuclear cells (PBMCs) were obtained from 12 patients with PV and 22 normal human controls,cultured with or without the presence of Dsg3 or phytohemagglutinin for 3 days.Flow cytometry was performed to detect the changes of T-lymphocyte subsets in PBMCs stimulated with Dsg3 and proliferation of T-lymphocytes.Results In patients with PV,the percentage of Th2 and Th1 cells was 12.17%±5.32% and 4.08%±1.50%,respectively in Dsg3stimulated PBMCs,9.84%±5.41% and 3.91%±1.38%,respectively in non-stimulated PBMCs.Increased percentage of Th2 cells was observed in Dsg3-stimulated and non-stimulated PBMCs from patients with PV compared with those from normal human controls (both P<0.05).After stimulation with Dsg3,there was a significant proliferation of T cells from patients,and the proliferation rate of CD4+T cells was 4.65%±3.28%,which was significantly higher than that from normal controls(P<0.05).Conclusion Dsg3 can induce the specific proliferation of CD4+T cells,especially Th2 type CD+4 T cells,from patients with PV.

Objective To investigate the clinicopathological features of undifferentiated embryo-nal sarcoma of the liver (UESL). Methods The clinical data of 9 UESL cases treated in our hospital between 1996 and 2007 were retrospectively analyzed. Results The patients were children and young adults. Clinical presentation was typically an abdominal mass that may be accompanied by pain and fe-ver. Tumors were all removed surgically in the 9 patients. Conclusion UESL is an unusual malignan-cy of the liver. Discrepancy of internal architecture between US and CT is one of the important charac-teristic of UESL. Whenever feasible, surgical resection should be attempted as a part of combination modalities. Modern rnultimodal treatment and supportive therapy might promote the survival rate.
