Objective To explore the correlation between the joint detection of cholinesterase(CHE),alpha-L-fucosidase(AFU) and alpha-fetoprotein(AFP)and primary hepatic cancer(PHC).Methods 56 cases of patients with PHC(PHC group),52 cases of patients with liver cirrhosis(LC group)and 60 cases of healthy individuals(control group)were enrolled in this study,and serum levels of CHE,AFU and AFP were detected and statistically analysed.Results Serum levels of CHE in patients with PHC were negatively correlated with levels of AFU and AFP(correlation coefficient was -0.889 and -0.797 respectively,P <0.05),the ser-um levels of CHE in patients with LC were also negatively correlated with levels of AFU and AFP (correlation coefficient was-0.598 and -0.653 respectively,P <0.05).The positive rates of joint detection of CHE,AFU and AFP in PHC group and LC group were higher than that in the control group,had statistically significant differences(P <0.05 ).Conclusion CHE,AFU and AFP are sensitive indicators of liver lesions,and the joint detection could provide reference value for diagnosis and monitoring pro-gression of PHC.

BACKGROUND: More recently,repair of skull defect with computer-designed prosthesis contributes to the revolutionary development of skull reconstruction technique. OBJECTIVE: To individually molded titanium mesh by computer-aided design (CAD) technique,and to observe the clinical application value of the titanium mesh in the repair of large-area skull defects in the fronto- temporo-parietal lobes. DESIGN,TIME AND SETTING: A retrospective case analysis was performed at the Department of Neurosurgery,Liuzhou People's Hospital between January 2006 and August 2007.PARTICIPANTS: A total of 16 patients comprising 12 males and 4 females,aged 16-52 years,suffered from skull defects in the fronto-temporo-parietai lobes following standard large trauma craniotomy and were recruited into this stud Two of these patients were complicated by hydrocephalus and received ventriculoperitoneal shunt. Skull defect area ranged between 9. 2 cm ×11.2 cm and 12.2 cm×14.6 cm. Skull defect neoplasty was performed in all patients 3-8months following standard large trauma craniotomy. METHODS: Titanium mesh patches were individually modeled by CAD,computer-aided manufacturing (CAM) and rapid shaping techniques and implanted into skull defect region. In addition,defect edge was fastened with titanium nails. MAIN OUTCOME MEASURES: Moulding effects and complications following skull defect neoplasty. RESULTS: A small amount of subcutaneous effusion was found in one patient and disappeared after liquid extraction and pressure dressing. Titanium mesh was firmly fixed with no loosening. Patients exhibited left-right symmetry,appropriate lateral curvature,no irregular umbilication or chewing dysfunction. All patients were followed for 3-18 months postoperatively and were satisfied with good resuRs,Le.,no complications,infection,material exposure,loosening,or collapse. CONCLUSION: CAD technique used for repair of skull defects is convenient,effective,and safe. This method can. reduce postoperative complications and improve repair effects.

Tibial plateau fracture is a common acute trauma of the knee joint. At present, there are many studies on its classification and treatment, and minimally invasive treatment has become a research hotspot and mainstream direction of tibial plateau fracture. We summarized the clinical results of minimally invasive treatment of more than 300 cases of tibial plateau fractures, and proposed the concept of core weight-bearing area on tibial plateau, that is, the core weight-bearing area of the tibial plateau of the knee joint under normal motion statuswhile walking and moderate-intensity running. We performed thinsection CT scanning of the knee joint in a male volunteer for three-dimension finite element modeling.The results showed that during the walking state (the load was twice that of gravity), the core weight-bearing area of the medial and lateral plateaus was 389 mm 2 and 363 mm 2, accounting for 33.2% and 42.9% of tibial plateau, respectively;during the moderate-intensity running state (the load was four times that of gravity), the core weight-bearing area of the medial and lateral plateaus was 418 mm 2 and 406 mm 2, accounting for 35.6% and 48.0%of tibial plateau, respectively. Accordingly, tibial plateau fractures are supposed to be divided into core weight-bearing fracture and non-core weight-bearing fracture, and there are significant differences in the treatment ofthese twokinds of fractures: reduction is more demanding for core weight-bearing fracture,and the fracture involves the core area closely, the anatomical reduction is sought; for non-core weight-bearing area, the reduction requirements can be appropriately low demanded, and even in some cases , for example simple avulsion fracture, marginal fracture, some tibial plateau Hoffa fractures,can be treated conservatively. In summary, during clinical diagnosis and treatmentpractice, orthopedic surgeons should take the core weight-bearing area fracture as the core of diagnosis and treatment, strictly evaluate the extent of fracture involvement, select targeted internal fixation materials, and target to promote more accurate, minimally invasive, and individualized treatment of tibial plateau fractures.

Objective To explore the role of CD 30 on CD4 + T lymphocyte and T lymphocyte subset activation in asthma pathogenesis.Methods Twenty seven asthma active attack patients,16 acute upper respiratory infection patients and 19 control children were randomly selected. Direct immunofluorescence flow cytometry was used to detect the CD 30 positive percentage on CD4 +cell; ELISA was used to detect the levels of interleukin(IL) 4 and IL 13 in culture supernatants of peripheral blood mononuclear cells(PBMC) and plasma total immunoglobulin E(IgE) level.Results Compared with control group and acute upper respiratory infection group, in asthmatic children the CD4 +CD 30 + percentage on CD4 + cell was elevated significantly; 2.The levels of IL 4 and IL 13 in supernatants of cultured lymphocyte were increased significantly, the plasma total IgE level was increased significantly;3.There was a significant positive correlation of CD4 +CD 30 + cell percentage with the levels of IL 4 and IL 13 in culture supernatants and plasma total IgE.Conclusions The cell that could produce Th2 derived cytokine may consist of CD 30 +cell;When CD 30 L combined with CD 30 on CD4 + cells ,it might result in Th2 cell proliferation ,develop and release Th2 derived cytokine; IL 4 and IL 13 could induce B cell production and secrete more IgE. It is suggested that CD 30 and imbalance of Th2 subset may play an important role in asthma pathogenesis.

Objective To investigate the safety and efficacy of radical nephrectomy plus inferior vena cava thrombectomy,and to evaluate the efficacy of preoperative temporary inferior vena cava filter placement and intraoperative application of liver transplantation techniques to reveal the inferior vena cava in order to avoid tumor thrombosis shedding and embolism.Methods The data of 42 cases (January 2004 to December 2010) of renal cell carcinoma with subdiaphragmatic thrombus were analyzed retrospectively.All these patients underwent radical nephrectomy plus inferior vena cava thrombectomy.Patients were implanted temporary inferior vena cava filter as preoperative routine.Patients with the tumor thrombi behind the liver were applied liver transplant techniques to free and turn liver to the left in order to reveal inferior vena cava,block blood flow according to priority and then finish the inferior vena cava thrombectomy.The filter was removed postoperatively on the same day,and the patients were followed up as routine.Results The operation of the 42 cases was successful without symptomatic tumor thrombus embolism perioperatively,while 1 case died of severe postoperative lung infection.The average operation time was 220 min (130-320 min),blood loss was 750 ml (200-2500 ml),and 12 cases had blood transfusion with an average of 800 ml (400-2000 ml).Forty-one cases were followed up with an average period of 36 months (6-60 months).Among the 37 cases without preoperative tumor metastasis,15 cases had metastases and 22 cases had disease-free survival.Conclusions Nephrectomy and inferior vena cava thrombectomy could be safe and effective for renal cell carcinoma with subdiaphragmatic thrombosis.Preoperative temporary inferior vena cava filter placement and intraoperative application of liver transplantation techniques to reveal the inferior vena cava can be effective to prevent tumor thrombosis shedding and embolism and improve surgical safety.

ObjectiveTo observe the effect of language rehabilitation on crossed aphasia.MethodsFive right-handed patients with aphasia secondary to acute stroke in the right hemisphere were studied by means of oral fluent of Aphasia Battery of China, the Western Aphasia Battery, grade criterion of the Boston Diagnostic Aphasia and Frenchy Dysarthria Battery. After thirty days language rehabilitation, these cases were studied by the same ways again.ResultsAll five cases were meted with the diagnosis criterion of crossed aphasia, and got a well language function recovery after rehabilitation.ConclusionThere were two types of crossed aphasia:mirror image aphasia and atypical crossed aphasia.Language rehabilitation is effective on crossed aphasia.

Objective To explore the ameliorative effects of standardized tertiary rehabilitation(STR)on the quality of life(QOL)of stroke patients with hemiplegia.Methods Eighty-two stroke patients were randomly divided into two groups:a rehabilitation group(R group)and a control group.All patients were given routine inter- nal medicine treatment,but STR was also administered to the R group.The QOL of all of the patients was assessed with the brief scale of quality of life(QOL-BREF)at the beginning,and at the end of the Ist month,3rd month and 6th month after stroke.Results There were two deaths in the control group,but no deaths in the R group.At ever- y stage,the R group returned better scores for physiological health,psychological state,social and environment rela- tionships,the subjective QOL and health items,and in comprehensive self-evaluation.QOL scores,except for social relationships,were consistently,significantly higher in the R group.The R group's QOL scores improved obviously in the first 3 months after stroke,and then more slowly in the next 3 months.Conclusions STR markedly improved the QOL of stroke patients.Their QOL scores improved obviously soon after stroke,but slowly later on.

Objective To examine the reliability,validity and sensitivity of FCA for stroke patients. Methods A total of 82 patients with stroke were divided into a treatment group and a control group randomly.The patients in the control group were given routine internal medicine treatment,while those in the treatment group were given standardized rehabilitation therapy in addition to the routine internal medicine treatment.All patients were as- sessed with FCA and Modified Barthel Index(MBI),at admission and the end of the 1st month,3rd and 6th month,respectively after the onset of stroke.The internal consistency,split-half reliability,content validity,crite- ria validity and sensitivity of FCA were tested.Repeat measure ANOVA and correlation analysis were used in the statistical analysis.Results There existed a good internal consistency(Cronbach?=0.901～0.973)as well as a good split-half reliability(R=0.949～0.981)of FCA.There was a medium to strong correlation among the 18 items scores of the FCA and FCA scores(P
