0.05). After operation about 50% cases (11/22) improved the menstrual dysfunction, and most cases avoid doing operation again in short period. Conclusion While cases chosen properly and adequate operative preparation, it is feasible and valuable to carry out cesarean section and myomectomy at the same time.

Objective It is important to precisely determinate the single nucleotide polymorphisms (SNPs) in many genes in‐cluding genes related with base excision repair (BER) pathway .This research is conducted to evaluate the role of polymerase chain reaction with confronting two‐pair primers (PCR‐CTPP) in analyzing the SNPs of BER pathway .Methods Four common SNPs of BER pathway (OGG1 Ser326Cys ,XRCC1 Arg399Gln ,APE1 Asp148Glu and‐141T/G in the promoter region) was detected with PCR‐CTPP .10 of the products were sent for genotype sequencing .Compare the results of PCR and sequencing to evaluate the accu‐racy of PCR‐CTPP .Results The genotypes were exactly the same as the sequencing .Conclusion The PCR‐CTPP was a reliable and rapid detective technology for SNPs genotyping .Its broadest application would be great help for gene variant analysis .

Objective To analyze the expression characteristics of chemotherapeutic related genes (ERCC1 ,BRCA1 ,APE1 , RRM1 ,TUBB3 and TS) in non-small cell lung cancer(NSCLC) and their associations with the pathological types to provide the ex-perimental evidences for clinical individual chemotherapy .Methods The immunohistochemical SP method was used to determine the expression of ERCC1 ,BRCA1 ,APE1 ,RRM1 ,TUBB3 and TS genes in 733 patients with NSCLC .Chi-square test was performed to analyze the gene expression characteristics among different pathological types .Spearman relationship was conducted to evaluate the associations among the six genes and different pathological types .Results The expression of BRCA1 ,TUBB3 and TS had sta-tistical differences among three pathological types (P<0 .01);and these three genes showed a relationship with the pathological type (r=0 .107 ,-0 .229 and 0 .168 ,respectively ,P<0 .01) .ERCC1 vs .BRCA1 ,ERCC1 vs .APE1 and APE1 vs .RRM1 showed the pos-itive correlation(r=0 .214 ,0 .316 and 0 .222 ,respectively ,P<0 .01) .Conclusion The chemotherapeutic related gene expressions of NSCLC are related with the clinical pathological types .And the expressions of multiple markers are associated with each other .The combined detection of the chemotherapeutic related markers and the pathological types would be helpful to the decision making of individual chemotherapy in clinic .

ObjectiveTo investigate the clinical characteristics and therapy of fresh cervical spinal cord injury without radiographic abnormality (SCIWORA) in children.MethodsThe materials of fourteen SCIWORA children (13 cases treated with non operative menthod, 1 case treated by atlantoocciptal fusion) were analyzed retrospectively.ResultsOne child was dead, and the other 13 cases had a 3-year follow up. Three children's symptoms had no change. According to ASIA criterion, there were 3 cases with grade A, 5 cases with grade B, 5 cases with grade C and 1 case with grade D before treatment. After treatment, there were 1 case recovered to grade B, 2 cases recovered to grade C, 5 cases recovered to grade D, 2 cases recovered to grade E.ConclusionSpinal cord injury caused by a short time dislocation of cervical vertebrae is the main reason of SCIWORA in children. The degree of the injury of spinal cord is related directly with the recovery of function of nervous system. Most patients can get satisfactory results by non operative methods. Operations are useful to the cases with obvious instability of cervical spine.

Objective:To investigate the risk factors of breast cancer complicated with deep venous thrombosis (DVT) in lower limb and to explore the predictive significance of the thrombus risk assessment model for patients with breast cancer. Methods:A total of 703 patients with breast cancer in Tianjin Medical University Cancer Institute and Hospital who suffered from DVT after operation dur-ing January 2013 to June 2016 were retrospectively selected as the thrombosis group. A total of 706 cases for the control group were selected by systematic sampling. The risk factors of lower limb DVT after surgery were investigated. The predictive values of the Khora-na and Caprini thrombosis risk assessment models for these patients were also presented in this research. Results:Age, BMI≥30 kg/m2, diagnosis by excisional biopsy, neoadjuvant chemotherapy, operation time>2 h, lipoprotein a (Lpa)>475.5 mg/L, protein C (PC)<102.5%, blood coagulation factor-Ⅷ(F-Ⅷ)>129.8%, and D-Dimer (D-D)>289.99 ng/mL had statistical differences between in the two groups (P<0.05). Significant difference between the groups was found in the Caprini scores (P<0.001) but not in the Khorana thrombo-sis risk assessment model (P=0.207). Conclusion:Age, BMI≥30 kg/m2, diagnosis by excisional biopsy, neoadjuvant chemotherapy, op-eration time>2 h, Lpa>475.5 mg/L, PC<102.5%, F-Ⅷ>129.8%, and D-D>289.99 ng/mL are the independent risk factors of thrombo-sis. The Caprini thrombosis risk assessment model may require complicated evaluation. Hence, a new model that is suitable for pa-tients with breast cancer must be developed.

Jinlingzi San is a formula frequently used in treating pain syndrome， first recorded in the Collection of Writings on the Mechanism of Disease， Suitability of Qi， and the Safeguarding of Life as Discussed in the 'Basic Questions' written by LIU Wansu in the Jin Dynasty. Jinlingzi San is composed of 2 Chinese medicinals Toosendan Fructus and Corydalis Rhizoma with a concise composition and exact clinical efficacy， having been included in the Catalogue of Ancient Classical Formulas （Second Batch： Han Chinese Medicine）. The formula name， historic evolution， medicine origins， composition， dosage， decocting methods， and ancient and modern clinical application were sorted out and analyzed with the bibliometric method. A total of 209 pieces of information were collected from ancient books and literature. After screening， 49 pieces of effective data involving 45 ancient books were included. Results showed that the name of Jinlingzi San was first recorded in Secret Formulas of the Yang Family written by Yang Tan in the Southern Song Dynasty and developed into 3 other versions of the decoction. The Jinlingzi San included in the Collection of Writings on the Mechanism of Disease， Suitability of Qi， and the Safeguarding of Life as Discussed in the 'Basic Questions' written by LIU Wansu invariably plays a dominant role. As for the 3 other versions， although they have the same name of Jinlingzi San， their composition and indications are different from those of the original formula， which were therefore viewed as prescriptions based on Jinlingzi San and also included in the research. The medicine origins and processing of Jinlingzi San are suggested： Toosendan Fructus is the dry mature fruit of Melia toosendan of Meliaceae， and the crude is used after cleansing without putamen. Corydalis Rhizoma is the dry tuber of Corydalis yanhusuo of Papaveraceae， which is used after impurity removal， cleaning， and drying. Depending on the conversion from the measurement system in the Jin Dynasty to modern measurement， it is suggested that Toosendan Fructus and Corydalis Rhizoma （41.3 g each） are ground into fine powder， and one dose includes 12.39 g of the powder， which should be taken with an appropriate amount of wine. If wine is not suitable for the patient， the decoction can also be taken with warm water. Jinlingzi San has the effects of soothing the liver， discharging heat， and activating blood to stop pain. As recorded in ancient books， Jinlingzi San is specialized in treating heart pain caused by reversal heat， chest and abdominal pain， hypochondriac pain， jaundice， hernia， and other diseases. Modern studies have shown that modified Jinlingzi San can be used in treating diseases involving the digestive system， the integumentary system， the gynecological system， the reproductive system， and other systems and has wide clinical application in treating epigastric pain， herpes zoster， dysmenorrhea， and other diseases. This study has made clear the key information of Jinlingzi San by textual research of ancient books and literature in the hope of providing a theoretical reference for the clinical application， set prescriptions， and new drug development.
