Objective To investigate the effects of laparoscopic operation in treating type Ⅲ child biliary atresia and its influence on postoperative infections .Methods 85 children cases of type Ⅲ biliary atresia were randomly divided into the conventional sur-gery group(OP group ,n=42) and the laparoscopic surgery group(LP group ,n=43) .The operation situation ,postoperative changes of inflammatory factors ,changes of liver function indexes before and after operation and postoperative infection were compared be-tween the two groups .Results The operative time of the LP group was longer than that of the OP group (P<0 .05) ,the intraoper-ative blood loss and the VAS scores of the LP group were less than those of OP group (P<0 .05) ,the postoperative eating recovery time of the LP group was earlier than that of the OP group (P<0 .05) ,the length of hospital stay of the LP group was shorter than that of the OP group(P<0 .05) and the postoperative infection rate of the LP group was lower than that of the OP group (P<0 . 05) .The liver function indexes recovery showed no statistically significant differences before and in postoperative 1 ,3 ,6 ,12 months between the two groups(P>0 .05) .Conclusion The laparoscopic operation and the conventional operation in treating type Ⅲ child biliary atresia have their own advantages and disadvantages .The appropriate operation mode should be selected according to the children′s actual situation .

This paper reviewed the progress in research on HER2 and gastric cancer,introducing the structure, signaling pathways,detection method and detection rate of HER2,the therapeutic effect of trastuzumab,a humanized anti-HER2 monoclonal antibody on gastric cancer,and the correlation between HER2 and prognosis of gastric cancer. Studies showed that HER2-positive was a factor with poor prognosis,and trastuzumab combined with chemotherapy was a new treatment option for patients with HER2-positive advanced gastric and gastroesophageal junction cancer or with liver metastases,which could significantly improve the prognosis.

OBJECTIVE:To establish a RP-HPLC method for the determination of seratrodast concentration in human plasma.METHODS:The sample was determined on Lichrospher C18 column with the mobile phase consisted of 0.02 mol?L-1 potassium dihydrogen phosphate(containing 0.1% triethylamine,pH=5.0)-acetonitrile(70∶30)at a flow rate of 1.0 mL?min-1.The column temperature was 30℃ and the detective wavelength was set at 268 nm.RESULTS:The linear range of seratrodast was 28～5 600 ng?mL-1(r=0.999 5)with the lowest detection concentration at 28 ng?mL-1.The recovery rates of seratrodast at low,middle and high concentrations were 102.9%,100.4% and 99.7%,respectively;and both intra-day RSD and inter-day RSD were all less than 6%.CONCLUSION:The method developed in this study is applicable for the determination of plasma concentration and pharmacokinetic study of seratrodast.

Objective To study the effect ofβ?sodium aescinate on the expressions of aquaporin?4 and aquaporin?9 in rats with spinal cord inju?ry. Methods A total of 150 rats were randomly divided into 3 groups:sham group(n=50),spinal cord injury(SCI)group(n=50)andβ?sodi?um aescinate group(n=50). The experimental animal models was established by modified Allen’s model. The Basso,Beattie and Bresnahan (BBB)locomotor rating scale and inclined plane test were used to evaluate rat behavioral consequences after injury.The immunohistochemical staining and western blotting assay were performed to observe the expressions of aquaporin?4 and aquaporin?9. Results Compared with sham group,BBB score and inclined plane test score of SCI group andβ?sodium aescinate group were significantly lower at each time point(P<0.05);however,the functional recovery was significantly better inβ?sodium aescinate group than in SCI group at each time point from 7 d after SCI(P<0.05). The aquaporin?4 and aquaporin?9 positive expressions of rats in sham group were lower significantly than rats in SCI group andβ?sodium aescinate group(P<0.05);however,the aquaporin 4 and aquaporin 9 positive expressions of rats inβ?sodium aescinate group was lower signifi?cantly than rats in SCI group at each time point(P<0.05). Conclusion β?sodium aescinate can protect the neurologic function in rats with spi?nal cord injury by decreasing aquaporin?4 and aquaporin?9 protein expression.

With the common application of total mesorectal excision (TME) technique,the proportion of sphincterpreserving surgery for the mid-low rectal carcinoma is significantly increased.Anastomotic leakage after sphincter-preserving surgery is the most severe complication of rectal surgery,and it is the main reason which will lead to other complications and death.Many researches on the early diagnosis,prevention and treatment of anastomotic leakage are conducted by surgeons at home and abroad,and a further understanding of this complication is deeply realized.

Objective To compare the safety and the long-term outcomes of laparoscopic and open radical resection for rectal cancer. Methods The clinical data of 602 patients who received radical resection at the Second Affiliated Hospital of Fujian Medical University from January 2000 to December 2008 were retrospectively analyzed.All patients were divided into the laparoscope group (324 patients) and the open group (278 patients).The numbers of dissected lymph nodes,lengths of proximal and distal resection margins,local recurrence rate,distal metastasis rate,overall survival rates and disease-free survival rates of the 2 groups were compared.All data were analyzed by the independent t test,chi-square test or Fisher exact probability. The survival rates were calculated by the life table method and were analyzed by the Wilcoxon (Gehan) test.Results The number of lymph nodes dissected in the laparoscope group and the open group were 21 ± 8 and 21 ± 9,with no significant difference between the 2 groups (t =1.120,P ＞0.05).The lengths of proximal resection margin were ( 15.1 ±1.3 )cm in the laparoscope group and (15.0 ±0.8)cm in the open group,with no significant difference between the2groups (t =1.452,P ＞0.05).The lengths of distal resection margin were (4.0 ± 1.6)cm in the laparoscope group and (3.3 ± 1.4) cm in the open group,with a significant difference between the 2 groups ( t =5.587,P ＜ 0.05 ).The overall local recurrence rate was 5.6％ (34/602),and no tumor recurrence was detected in the incision and port-site.The local reccurence rates were 6.2％ (20/324) in the laparoscope group and 5.0％(14/278) in the open group,with no significant difference between the 2 groups (x2 =0.363,P ＞ 0.05 ).The overall distal metastasis rate was 11.5％ (69/602),and the distal metastasis rates were 11.1％ (36/324) in the laparoscope group and 11.9％ (33/278) in the open group,with no significant difference between the 2 groups (x2 =0.085,P ＞0.05).The 3- and 5-year survival rates were 87.8％ and 83.0％ in the laparoscope group,and 84.9％ and 79.3％ in the open group,with no significant difference between the 2 groups (P ＞0.05).The 3- and 5-year tumor-free survival rates were 79.4％ and 69.2％ in the laparoscope group,and 79.7％ and 73.1％ in the open group,with no significant difference between the 2 groups ( P ＞ 0.05 ).The follow-up rate was 81.2％ (489/602).Forty-nine patients died,including 20 patients in the laparoscope group and 29 patients in the open group.Conclusion Laparoscopic radical resection for rectal cancer is reliable in the oncological efficacy,and is possible to achieve the similar long-term outcomes as that of open surgery.

Objective To analyze the clinical features of elderly patients with acute cerebral infarction with early seizures and pathogenesis mechanisms,clinical therapy and prognosis.Methods The clinical data of 66 cases of elderly patients with acute cerebral infarction complicated with seizures were retrospectively analyzed.Results The analysis found that 66 patients had 2 weeks after the onset of acute cerebral infarction,focal motor seizures in which patients were 37 cases,accounting for 56.1%;generalized tonic-clonic seizures in patients of 21 cases,accounting for 31.8%;bureau focal status epilepticus patients 8 cases,accounting for 12.1%.All patients were 2 to 6 months after treatment withdrawal,and followed up for 5 months,64 patients with no recurrence,2 patients needed long-term medi-cation to control the disease.Conclusion Elderly patients with acute cerebral infarction after seizures need aggres-sive treatment and control of cerebral disease,but patients need to control seizures,which can reduce brain injury,help to improve the prognosis of patients.
