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.

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.

Conclusion Short fragment target gene less than 500 bp may be synthesized by this method.

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.

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.

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.

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.

OBJECTIVETo study the inhibition and killing effect of transgenic LIGHT umbilical cord blood mesenchymal stem cells (UCBMSCs) on stomach carcinoma.

METHODSThe LIGHT gene was recombined to construct the transfer plasmid pGC-FU-LIGHT by infusion technique. The 293T cells were co-transfected with the transfer plasmid pGC-FU-LIGHT, the construction plasmid Helper 1.0 and the envelope plasmid Helper 2.0 with the help of lipofectamine 2000 to produce lentiviral particles. Transgenic UCBMSCs(MSC-LIGHT) and empty carrier UCBMSCs (MSC) were obtained. Human gastric cancer cell SGC-7901 was injected into nude mice subcutaneously groin. The model of transplanted human gastric cancer cell SGC-7901 in nude mice was established. Tumorigenesis nude mice were separated into three groups randomly with 5 in each group: MSC-LIGHT group, MSC group, and NS group. Three groups of nude mice were injected around the tumor with MSC-LIGHT, MSC and NS every other day for 3 times. Four weeks later, the transplanted gastric cancer volume was measured. The expressions of LIGHT in the three groups were determined by RT-PCR and ELISA method. The necrosis area in the tumors was calculated under pathological examination.

RESULTSThe average volume of transplanted tumor was(0.45±0.25) cm(3) in MSG-LIGHT group, (0.64±0.36) cm(3) in MSG group, and(1.21±0.79) cm(3) in NS group, and the difference was statistically significant(P<0.05). The LIGHT mRNA was 2.96±0.27, 1.23±0.47, and 0.73±0.10 respectively. The LIGHT protein was(167.89±2.31), (73.22±5.74), and (49.66±5.25) ng/L. The differences were all statistically significant among the three groups(both P<0.01). Pathological examination showed that the necrosis area was largest in MSC-LIGHT group.

CONCLUSIONTransgenic UCBMSCs secret LIGHT in a paracrine manner, which has inhibition and killing effects on stomach carcinoma.

OBJECTIVETo evaluate the feasibility and the therapeutic effect of orthognathic surgical procedures combined distraction osteogenesis and scapular flap for correction of progressive hemifacial atrophy.

METHODS5 cases with progressive hemifacial atrophy were treated. 1 mild case was treated with microsurgical de-epithelia scapular flap (MDSF) and genioplasty in one stage. The 2 moderate cases were treated with Le Fort 1 osteotomy following by sagittal split ramus osteotomy and genioplasty at the first stage. 3 - 6 months later, the MDSFs were used for augmentation. 2 sever cases were treated with bimaxillary distraction osteogenesis on the affected side. 3 - 4 months later, the distraction devices were removed and MDSFs were transplanted.

RESULTSThe facial asymmetry was obviously improved. The orthognathic procedures and distraction osteogenesis achieved good therapeutic effect. All the MDSFs were survived.

CONCLUSIONSThe progressive hemifacial atrophy can result in very severe deformity when it occurs in very young age. The combined deformity of bone and soft tissue can be effectively corrected by orthognathic procedures combined with distraction osteogenesis and scapular flap transplantation.
