The relationship between adjunctive drug (AD) and other drugs in a compound prescription and the actions of AD are very complex. From historical view, it showed the adjunctive action of AD was only be recognized with emphasis on its action as corrigent and effect on complications. In modern medicine, the actions of AD were reduced to 3 aspects: the assistant action, the restrained action and the corrigent action, with new contents added in each aspect on the basis of the ancient understanding. The authors hold that to master the various actions of AD and its relationship with other drugs in the prescription would be helpful in choosing them accurately and scientifically, thus to contribute the treatment in accordance with disease.

Objective To investigate the prevalence and influential factors of workplace violence (WPV) against nurses in general hospitals of Suzhou. Methods A total of 2110 staff nurses from 13 general hospitals in Suzhou were investigated with the Modified Version of Hospital Workplace Violence Questionnaire. Results During the past one year,68.9% (1454/2110) nurses investigated suffered from WPV.Working departments,marital status, strong support,etc,were the leading impact factors of WPV. Conclusions Nurses′experience of WPV is a prevalent phenomenon in general hospitals of Suzhou. It is urgent for hospital administration to raise attention to WPV and take effective measures,to reduce the occurrence of WPV.

TCM syndrome differentiation system (TCM-SDS) possesses a complex nonlinear characteristic, which determines the falt that the evaluation of TCM efficacy should not be simplified to a causal or linear relationship. Previous selected indexes and methods for evaluating curative effect of Child's pneumonia have their limitations. This paper mainly introduces several thoughts and methods formed in the exploratory researches, employing data mining technology in this field. We believe that efficacy evaluation research of Child's pneumonia on the basis of standardized study of TCM-SDS is a scientific work. Applying data mining method in processing enormous and multilayer information of TCM differentiation has strong advantages in screening evaluating indexes of Child's pneumonia. Meanwhile, some major concerning technical categorizations and implementing strategies for the research are also introduced.

Notopterygium incisum is the important medicinal materials of the Tibetan-Qiang medical system in China, also one of the rare and endangered medicinal materials in the Plateau areas in the meantime. Taking the planting of in Sichuan province as an example, research on the N. incisum in Sichuan utilize remote sensing and GIS techniques, bind growth environment factor, including height factor, average annual precipitation, average annual temperature, forest information, were chosen according to habitat conditions. And combine field measurement to verify. The results indicate that N. incisum resources in Sichuan province were mainly distributed in the alpine valley and the northwest of the plateau, which suitability distribution areas of 4145 km2 approximately and accounting for 2% of the total area. Suitability areas accounting for more than 2% of the respective total area in Heishui county, Lixian county, Xiaojin county, Kangding county, ect. According to the field investigation and the related document information record, drawn that the suitability distribution based on RS and GIS were corresponded with the actual distribution areas of N. incisum resources. It's feasible to divide the suitability distribution area of N. incisum using RS and GIS, which will provide a scientific basis for a comprehensive investigation of the distribution as well as its rational exploitation and protection.

OBJECTIVEThe purpose of this article was to observe the effect of by microwave thermocoagulation on oral benign tumor and to provide theoretical basis for clinic treatment of oral benign tumor.

METHODS165 patients with oral benign tumor were included. There were 83 patients with oral bursa cyst, 42 patients with hemangioma, 19 patients with papilloma, 14 patients with fibrous hyperplasia and 7 patients with epulis. All the patients were treated by WB-100 microwave thermocoagulation.

RESULTS144 patients were effective after the first treatment and 21 patients were effective after the second treatments. No side effect and reoccurrence were found after 3 years.

CONCLUSIONMicrowave thermocoagulation is an effective and safe method in clinic treatment of oral benign tumor.

OBJECTIVETo improve the diagnosis and treatment of primitive neuroectodermal tumors (PNET) of the pancreas.

METHODSOne patient with PNET of the pancreas was reported in this article. The corresponding literatures on the diagnosis and treatment was reviewed.

RESULTSThe patient was diagnosed as pancreatic PNET by her clinical, microscopic, and immunohistochemical features as well as cytogenetic analysis after the resection of the tumor located in the uncinate process in PUMC Hospital. Radiochemotherapy was given after the operation for 8 months and no recurrence was observed. Since PNET of pancreas have no specific clinical symptoms and most patients have jaundice and/or abdominal pain, the diagnosis depended on the immunohistochemical features of positive P30/32(MIC2) and at least two of the neural markers. The cytogenetic analysis showed translocation mainly harbored the characteristic t (11; 22) (q24; q12). Since pancreatic PNET were highly aggressive, early chemotherapy, close follow-up, and immediate surgical interventions were required as early as possible.

CONCLUSIONPNET can occur in pancreas, and diagnosis and treatment should be made as early as possible to improve the outcome.

Objective To analyze and compare the MRI appearances of ovarian thecoma with pathologic findings in order to improve the knowledge of the disease.Methods Nineteen cases of ovarian thecoma confirmed by histopathology were analyzed.MRI morphological characteristics and signal intensity of the lesions were observed and compared with findings of pathomorphology.Correlation analysis between tumor size and amount of ascites was made.Results Ovarian thecoma displayed iso-or hypointense signal on T_1WI and significant hypointensity in the focal lesion on T_2WI.Hyperintensity occurred when cystic degeneration of the lesions existed.Fibrous septation was detected in some lesions.After enhancement,most lesions showed mild early enhancement with slight increase on the delayed phase.Pathological necrosis and cystic degeneration were seen in 9 cases which corresponded to the number and shape of the cystic lesions on MRI.A large amount of collagen hyperplastic was found between the oncocytes microscopically in 15 cases, which displayed significant hypointensity in the focal lesion on T_2WI;another 4 cases showed relatively less amounts of collagen hyperplastic and more oncocytes,which appeared moderate intensity in the focal leisom on T_2WI.The amount of ascites was not significantly correlated with the lesion size(r=0.43,P=0.10). Conclusions Hypointensity on T_2WI and mild enhancement pattern due to poor blood supply are the characteristics of ovarian thecoma.The MR findings can reflect the pathologic features of the tumor,which is helpful in the diagnosis and differential diagnosis.

OBJECTIVETo explore changes of Clara cell protein (CC16) and surfactant protein-D (SP-D) in the serum of patients with silicosis.

METHODThe concentrations of CC16 and SP-D were measured in the serum by sandwich enzyme-linked immunosorbent assays. The subjects consisted of 30 healthy volunteers and 90 silica-exposed workers including silica-exposed group, the silicosis of suspects group (0(+)) and the silicosis phase I group, 30 subjects each groups.

RESULTSThe concentrations of CC16 in the serum was significantly decreased in silica-exposed workers compared to controls (P < 0.01); The concentrations of CC16 in the serum were higher in lifelong nonsmokers than the current smokers in control subjects (P < 0.05), but they were no differences between lifelong nonsmokers and current smokers of 90 silica-exposed workers. Compared with control subjects, the levels of SP-D in the serum of silicosis suspects (0(+)) and silicosis phase I groups were significantly elevated (P < 0.01, respectively), which were also higher than silica-exposed group (P < 0.05 and P < 0.01, respectively), Discriminant equations set by CC16 and SP-D were used in diagnosis of silicosis, and the rate of accuracy in healthy volunteers, the silica-exposed group and the silicosis phase I group were 86.7%, 86.7% and 76.7%, respectively, The total rate of correct classification hit 84.2%.

CONCLUSIONThe serum CC16 of long-term silica-exposed workers is decreased, and SP-D is increased gradually.
