Co-culture of sciatic nerve with salivary adenoid cystic carcinoma cell was chosen as control group RESULTS In contrast to control group , the promotion growth and chemotactic growth of Schwann cell was blocked by K252a (P

Objective　To study the indication, contraindication and short-term clinical effects of stereotactic radiotherapy (X-knife) in lung cancer. Methods　A total of 56 cases (Treatment group) of lung cancer were treated with X-knife composing of the modern 3-D treatment planning system and the stereotactic body frame, and SL-75 accelerator. And another 53 cases only treated with routine external radiation served as the control. In treatment group, 42 cases received 50 Gy radiation, at 2 Gy per day, 5 d per week in the upper mediastinum, hilus of lung, below the primary focus first and then underwent X-knife for the primary focuses, and other 14 recurrent and metastatic cases received irradiation of 8-12 Gy per day, 5 d by X-knife alone. Results　The actually reexamination rate for 1, 3, 6, and 12 months after X-knife treatment in 78 focuses from 56 cases was 79.5% (62/78), 89.8% (70/78), 87.2% (68/78) and 78.2% (61/78) respectively. The focuses reappeared in 3 months after the treatment and the growth rates of focus in 3, 6, and 12 month after the treatment were 2.6% (2/78), 5.1% and 9% (7/78) respectively. There were 2 focuses received a second treatment with X-knife because no change after the first one. Both the 1-and 2-year survival rates of 36 cases of the primary lung cancer in the treatment group were higher than that of control group (89.1%, 53.9% and 77.4%, 39.6%). Conclusion　The stereotactic radiotherapy is of applicable and prospective in the treatment of lung cancer. The indications include: ①As a boost dose in case when primary focus is less than 5 cm after the first external radiotherapy may reduce the exposure of lung tissue to x-ray and the occurrence of radiation pneumonia; ②Treatment for the recurrence after radiotherapy and operation; ③Radical treatment for the metastatic focus less than 5 cm. Attention must be paid to when multiple treatment is carried on the volume of the focus, the Karnofsky scores and the general condition when stereotactic radiotherapy combined with X-knife for lung cancer.

Objective To investigate the changes of serum trace elements and nutritional proteins in children with acute lymphoblastic leukemia and acute myeloid leukemia at the stage of remission.Methods Erythrocyte count,hemoglobin,serum levels of total protein,albumin,iron,ferritin,transferrin,lactate dehydrogenase,ceruloplasmin,cuprum,zinc and their ratio were measured in 43 patients with acute lymphoblastic leukemia,19patients with acute myeloid leukemia at stages of remission(remission groups),and 30 healthy controls(control group)enrolled from Shanghai Children's Medical Center using atomic absorption spectrometry,nophelometry assay,dry chemical method,and chemiluminescence method.The differences of these indicators between remission groups and control group were analyzed.Results Serum levels of total protein(P=0.454),iron(P=0.769),transferrin(P=0.903),and zinc(P=0.343)were not significantly different between the remission groups and the control group.Serum levels of ferritin(P=0.000),lactate dehydrogenase(P=0.000),ceruloplasmin(P=0.000),cuprum(P=0.002),and Cu/Zn ratio(P=0.003)in the remission groups were significantly higher than those in control group.On the contrary,erythrocyte count(P=0.000),hemoglobin(P=0.000)and albumin(P=0.046)were significantly lowerin remission groups than those of control group.Serum levels of all detected indicators were not significantly different between the acute lymphoblastic leukemia remission group and acute myeloid leukemia remission group(P>0.05)except for lactate dehydrogenase(P=0.025).Conclusion At the remission stage of acute lymphoblastic leukemia and acute myeloid leukemia,serum levels of some trace elements and nutritional proteins gradually returned to normal,and the original balance is established again.

OBJECTIVE:To investigate the effect of different doses of oxaliplatin on the efficacy and safety and related index-es of patients with hepatocellular carcinoma(HCC)after transcatheter arterial chemoembolization(TACE). METHODS:100 HCC patients were randomly divided into control group (50 cases) and observation group (50 cases). After TACE,control group re-ceived arterial infusion chemotherapy of 40 mg/m2 oxaliplatin,once a day+20 mg Epirubicin hydrochloride for injection,once a day,with little lipiodol. Observation group received arterial infusion chemotherapy of 80 mg/m2 oxaliplatin (the same usage with control group)+Epirubicin hydrochloride for injection(the same dosage with control group),with little lipiodol. Alanine aminotrans-ferase (ALT),aspartate aminotransferase (AST),total bilirubin (TBIL),white blood cell count (WBC) and alpha-fetoprotein (AFP) in 2 groups after 3 d treatment were observed,and the total overall survival (OS) and the incidence of adverse reactions were followed-up. RESULTS:Abdominal pain,incidences of nausea and vomiting,ALT,AST and TBIL in observation group were significantly higher than control group,WBC was significantly lower than control group,the differences were statistically sig-nificant (P<0.05). There were no significant differences in fever,hair loss,incidence of peripheral neurotoxicity,OS in 1 year and 3 years,and AFP in 2 groups(P>0.05). CONCLUSIONS:Compared with 40 mg/m2 oxaliplatin,80 mg/m2 can reduce the in-cidence of abdominal pain,nausea,vomiting,but other effects are poor than 40 mg/m2,and it can not prolong the survival time of patients.

OBJECTIVE:To observe the clinical efficacy of entecavir combined with intervention in the treatment of liver cancer patients with HBV DNA-negative hepatitis B. METHODS:100 liver cancer patients with HBV DNA-negative hepatitis B were random-ly divided into observation group and control group,50 cases in each group. Control group received intervention,percutaneous punc-ture of femoral artery,then injected Pirarubicin hydrochloride for injection + lipiodol in parent artery until blood stagnation,and also conventional liver protection therapy was conducted;observation group additionally received 1 mg Entecavir tablet,qd,for continuous 6 months. Clinical efficacy,HBV DNA quantification,Child-Pugh score and liver function indexes in 2 groups were compared. RE-SULTS:The total effective rate in observation group was 44.0%,which was significantly higher than control group(26.0%),the dif-ference was statistically significant(P<0.05). There were no significant differences in HBV DNA quantification,Child-Pugh score and liver function indexes between 2 groups(P>0.05). After treatment,HBV DNA quantification,Child-Pugh score,fetoprotein,alanine aminotransferase, total bilirubin and aspartate aminotransferase significantly decreased in observation group,the differences were statis-tically significant compared with control group (P<0.05). CONCLUSIONS:Entecavir combined with intervention can obviously im-prove the clinical efficacy and liver function indexes of liver cancer patients with HBV DNA-negative hepatitis B.

Objective To provide basic and scientific data for diagnosis of Kashin-Beck disease (KBD) and development of children in the endemic disease region of Xinghai, Qinghai Province. Method In March 2012, the radiographs of right hand of 278 children aged 7 - 12 in KBD areas from Xinghai County, Qinghai Province were taken by X-ray, and then these phalange bones were measured with electronic digital vernier caliper. All data were analyzed with SPSS 17.0. Results The length of middle and end phalanges offingers of the forefinger, middle phalanges offinger of the middle finger and middle phalanges offinger of the pinky of girls aged 8 [(15.76 ± 1.39), (10.86 ± 1.06), (18.69 ± 1.46) and (12.26 ± 1.51) mm] were higher than those of boys [(14.71 ± 0.96), (10.24 ± 0.87), (17.76 ± 0.99) and (11.27 ± 1.42) mm], and the differences were statistically significant (t = 3.058, 2.174, 2.603, 2.346, all P< 0.05). The length of end phalanges offinger of the forefinger and middle phalanges offinger of the ring finger of girls aged 11 [(12.37 ± 0.86), (19.71 ± 1.32) mm] were higher than those of boys [(11.56 ± 1.01), (18.67 ± 2.03) mm] with significant differences (t = 2.938, 2.070, all P< 0.05). There was no significant difference of length of phalange bones between boys and girls at other age groups (all P>0.05). 7 year old age group, the width of phalange bones(proximal thumb, middle phalanges offingers of the forefinger, proximal and end phalanges offinger of the middle finger, proximal phalanges offinger of ring finger and middle phalanges offinger of the pinky) of boys was significantly thicker than girls (t = 2.291, 3.151, 3.131, 2.814, 2.235, 2.129, all P < 0.05). The 8 year old age group, the width of proximal phalanges offinger of ring finger of boys was significantly thicker than girls (t = 2.952, P< 0.05); 10 year old age group, the width of proximal phalanges offinger of the middle finger, proximal and middle phalanges offinger of ring finger of boys was significantly thicker than girls (t = 2.114, 3.829. 2.234, all P< 0.05); 11 year old age group, the width of middle phalanges offinger of forefinger and ring finger of boys was significantly thicker than girls (t = 3.219, 2.094, all P< 0.05); 12 year old age group, the width of end phalanges offinger of thumb and forefinger, proximal and end phalanges offinger of the pinky of boys was significantly thicker than girls (t=2.181, 3.973, 3.128, 2.237, all P<0.05);the rest and comparison, no statistically significant difference (P>0.05). Conclusion The development of phalange bones of children aged 7 - 12 is in accordance with the specific changes of development at different stages.
