Objective To evaluate the role of calcium/calmodulin-dependent protein kinase Ⅱ (CaMK Ⅱ) in the up-regulation of expression of Cav3.2 T-type calcium channels in spinal cord in a rat model of neuropathic pain (NP).Methods Forty-eight male Sprague-Dawley rats,aged 3 months,weighing 220-250 g,were randomly divided into 6 groups (n =8 each)∶ sham operation group (group S),group NP,dimethyl sulfoxide group (group D) and different concentrations of a specific CaMK Ⅱ inhibitor KN93 groups (groups K1-3).NP was produced by chronic compression of dorsal root ganglion.The rats in groups D and K1-3 received a single intrathecal injection of dimethyl sulfoxide and KN93 15,30,60 nmol/L (10 μl),respectively,on 5th day after NP.Paw withdrawal threshold to von Frey filament stimulation (MWT) and paw withdrawal latency to thermal nociceptive stimulus (TWL) were measured before NP,before intrathecal injection on 5th day after NP,and at 30 and 60 min and 3,6 and 8 h after intrathecal injection on 5th day after NP (T1-7).The rats were sacrificed after the measurement of pain threshold at T7 and their lumbar enlargements were removed to detect the expression of Cav3.2 mRNA and protein using Western blot and RT-PCR.Results Compared with group S,MWT was significantly decreased,TWL was shortened and the expression of Cav3.2 mRNA and protein was up-regulated in NP,D and K1-3 groups (P ＜ 0.05).Compared with NP group,MWT was significantly increased,TWL was prolonged and the expression of Cav3.2 mRNA and protein was down-regulated in a concentration-dependent manner in K1-3 groups (P ＜ 0.05),and no significant change was found in the parameters mentioned above in group D (P ＞ 0.05).Conclusion CaMK Ⅱ is involved in the development and maintenance of chronic NP by up-regulating the expression of Cav3.2 T-type calcium channels in rat spinal cord.

Objective To evaluate the effect of transcatheter arterial chemoembolization (TACE) and delayed surgery for infant hepatoblastoma.Methods TACE was performed with the initial digital subtractive angiography (DSA) under general anesthesia 1-3 times in 8 infants with huge hepatoblastoma, whose age was 2 to 12 months. DSA was done via arterials in hepatoblastoma each time before chemoembolization. The arterials were perfused with chemodrugs and suspensions in ultrasome iodized oil , and were blocked with spring rings. DSA findings indicated that the tumor shrank without new tumorous arterials after 1 month in 6 cases, and 4 of them showed no tumorous staining, and the delayed surgery was performed successfully 1 week later in 6 infants. One boy underwent systemic chemotherapy alone during 6 months after 3 times of TACE. Results TACE therapy did not encounter any major technical problem or toxic reaction caused by chemotherapy. The following DSA test 4 weeks later did not detect any new tumorous vessels in 6 cases. Six children received TACE and surgery had been followed-up with no tumor recurrence for months averagely. The boy underwent TACE and venous chemotherapy for 6 months , without surgery , had been followed-up for 48 months until the present report. CT, AFP and DSA did not show any hints of tumor recurrence. Six cases receiving 3 times TACE combined with surgery survived without tumor recurrence. Conclusions TACE is a very effective, safe and helpful therapy for hepatoblastoma, which stressed the repeated use of spring ring to block tumor vessels lastingly if necessary. If surgery is required, DSA test is needed beforehand to detect new tumorous vessels or neoplasm. If there is any , TACE is repeated. TACE combined with surgery may provide an additional promising choice in the treatment of hepatoblastoma, and repeated TACE alone may cure hepatoblastoma in infants.

To explore the correlation between the ecological factors and the contents of podophyllotoxin and total lignans in root and rhizome of Sinopodophyllum hexandrum, podophyllotoxin in 87 samples (from 5 provinces) was determined by HPLC and total lignans by UV. A correlation and regression analysis was made by software SPSS 16.0 in combination with ecological factors (terrain, soil and climate). The content determination results showed a great difference between podophyllotoxin and total lignans, attaining 1.001%-6.230% and 5.350%-16.34%, respective. The correlation and regression analysis by SPSS showed a positive linear correlation between their contents, strong positive correlation between their contents, latitude and annual average rainfall within the sampling area, weak negative correlation with pH value and organic material in soil, weaker and stronger positive correlations with soil potassium, weak negative correlation with slope and annual average temperature and weaker positive correlation between the podophyllotoxin content and soil potassium.
