Objective To study the clinical characteristics and effects of surgical treatment of children with thalamic tumors.Methods The clinical data of 22 cases were retrospectively studied and followed-up 6 months to 9 years.Results There were 13 boys and 9 girls,their ages ranging from 3 to 13 years.The average duration of symptoms before diagnosis about 2 months.Headache and papilledem were the most symptoms and signs,respectively.Most children′s thalamic tumors were low grade tumors with clear verge.In this group,good results were obtained that total remove 9 cases,subtotal remove 8 cases,partial remove 3 cases,biopsy 2 cases and no surgical death.Conclusions Clinical character of children thalamic tumors is distinct and good surgical results in the nearly future.The long results are determined by type of pathology.

Objective To observe the effects of treating knee osteoarthritis(KOA)combined with synovitis with Gubiqing,and discuss its mechanism.Methods A total of 60 cases with KOA were randomly recruited into a control group and a treatment group,30 cases in each.TCM symptoms,signs and health assessment questionnaire(HAQ)were observed before and after the treatment.Results The tohal therapeutic effect was 90%and 70%in the treatment group and the control group respectively.There was significant difference between the two group(χ~2=48,P=0.003).Body signs and HAQ were also greatly improved in the treatment group(t=0.004、P=0.008).Conclusion Gubiqing can not only restrain chondrocyte apoptosis in knee osteoarthritis combined with synovitis,but also relive the damage of articular cartilage.

Objective To explore the pattern of cognitive impairments mainly caused by the white matter lesions(WML) in the frontal lobe in patients with subcortical ischemic vascular disease (SIVD).Methods Fifty SIVD patients were divided into severe WML group (visual score >3, n=27) and mild WML group(visual score ≤3, n=23) according to their severities of the WML in frontal lobe .Seven patients without SIVD were collected as controls .All patients underwent a set of neuropsychological battery ,and the results were analyzed .Results There was no statistical significance among three groups on basic data .Compared with mild WML group and control group , non frontal white matter scores and numbers of lacunes in frontal lobe of severe WML group were significantly higher ( all P=0.000).Compared with mild WML group,the Montreal cognitive assessment scale in severe WML group were significantly lower ( P=0.047 ) , and scores related to the executive function were significantly lower ( P=0.006 ) , even after adjusting the numbers of lacunes in frontal lobe ,there was statistically significant difference (P=0.038). Multiple regression confirmed that the Z scores of executive functions were mainly affected by white matter lesions located in the frontal lobe ( P=0.000 ) .Conclusion WML located in the frontal lobe mainly affect the executive function in patients with SIVD .

Objective To isolate and identificate a specific new gene highly related to human bladder cancer and to investigate the carcinogenesis mechanism and genetic susceptibility. Methods Normal bladder epithelia and cancer tissue collected from 8 cases of primary bladder transitional cell carcinoma were studied using the high performance?sensitive technique of mRNA differential display.The differential fragments were found by comparing with genetic expression. 6 of them were reamplificated?cloned?sequenced,and performed the autoploidy index in the public database of genbank. Results (1)37 differential fragments have been isolated.36 of which are expressed or highly expressed in cancer tissues,but not so or lowly expressed in normal tissues;while it has been expressed in 1 normal tissue but not in the cancer tissue.(2)Results of indexing:1 is homologous to TBX3 (T box gene),autoploidy 99%.1 is homologous to cl.Ca4 gene (member 4 of Calcium activated chloride channel gene family), autoploidy 99%.1 is homologous to Cu,Zn SOD gene (Cu,Zn superoxide dismutase),99%.The remaining fragments are not homologous to unknown sequences in the public database of genbank,assigned as YHHQ1,XHL,LHX. Conclusions (1)It is verified at genetic level the relation between the conment's increasing of Cu,Zn SOD in bladder cancer derived tissue and the occurrence,advance of bladder cancer.(2)The relation between TBX3,cl.Ca4 gene and human carcinoma has been observed.(3)YHHQ1 may be the new candidate of anti oncogene related to bladder cancer.XHL and LHX may be the new candidates of oncogene related to bladder cancer.

Femoral neck fractures in pediatric fractures account for less than 1% which is very rare, and its mechanism is commonly caused by high-energy trauma. If children with femoral neck fracture cannot receive timely and effective treatment, they are at high risk of avascular necrosis of the femoral head (AVN), coxa vara, bone nonunion, premature physeal closure, leg length discrepancy and other complications. Surgical treatment is currently preferred over conservative treatment, which has a higher complication rate. Among them, AVN is one of the most common and the most difficult complications to manage. So far, no effective treatment measures and reliable predictors have been reported, and the related factors affecting the occurrence of AVN have also been controversial. Once femoral head necrosis occurs in children, the prognosis is not ideal due to the lack of appropriate treatment methods. Therefore, this paper reviews the research progress on the related factors of AVN after femoral neck fracture in children based on the literature reports in the past decade.

OBJECTIVE:To compare the substitution between the gray relation analysis( GRA) and the orthogonal design(OD) in data processing. METHODS:Take the four factors including the molar ration of drug and cyclodextrins,the agitating time and speed,and the temperature of complexation that influenced on loaded dosage of ursolic acid complex as example to analysis with 2 kinds of methods. RESULT:The result of analysis was similar by 2 kinds of methods,the molar ration of drug and the temperature of complexation were the major influence factors. CONCLUSION:When the data cannot fit to the analysis of range of OD,GRA can be used to it.

Objective To investigate the expression changes of nuclear factor-kappa B(NF-kB) and intercellular adhesion molecule-1(ICAM-1)in rats with severe acute pancreatitis(SAP)and the effect of pretreatment of pioglitazone,a specific peroxisome proliferator-activated receptor?(PPAR?),)ligand, on the development of SAP.Methods Fifty-four SD rats were divided into sham operation group(C), SAP group(A)and pioglitazone pretreatment group(Ⅰ).The SAP was induced by retrograde infusion of 5% sodium taurocholate(0.1 ml/100 g)into the biliopancreatic duct.The rats inⅠgroup were intraperi- toneally injected with pioglitazone(2 mg/100 g)two hours before operation.The rats were sacrificed at 3,6 and 12 hrs,the blood,ascites and pancreatic tissues were collected(6 rats once for each group). The expressions of NF-kB and ICAM-1 in pancreatic tissues were measured by immunochemistry,mean- while the serum amylase,the amount of ascitic,pancreatic wet/dry ratio were measured.The pathologi- cal changes of pancreatic tissues were observed by immunochemistry staining with hematoxylin and eosin and the score of the tissues were evaluated.Results Pretreatment with pioglitazone could significantly attenuated the severity of SAP,including reduction of amylase and ascites,and the mass and pathological scores of the pancreatic tissue were decreased after 6 hrs of medication.The expression of ICAM-1 and NF-kB activity were inhibited.Conclusions Above findings demonstrate that pioglitazone can attenuate the severity of SAP by inhibition of ICAM-1 expression and NF-kB activation.The beneficial effects of pioglitazone might be due to its anti-inflammatory activities.The pioglitazone can be used as a new drug in treatment of SAP.
