Adrenal gland vein sampling is an interventional method to get the blood samples from the adrenal gland vein. The blood is obtained via a catheter which is selectively inserted in the adrenal gland vein. This technique is mainly used to be diagnostic for primary hyperaldosteronism. A full knowledge of the anatomy and variations of the adrenal gland vein, serious preoperative preparation and skilled catheterization manipulation are necessary for obtaining sufficient blood sample and for reducing the occurrence of complications. Providing the physicians with definite diagnostic evidence and being technically feasible, adrenal gland vein sampling should become one of the routine examinations for clarifying the cause of primary hyperaldosteronism.

Objective To review the study on the risk factors and prognosis of laparoscopic cholecystectomy remedied by laparotomy. Methods Five hundred cases of laparoscopic cholecystectomy patients in our hospital were collected as a research object ,using univariate analysis and multivariate logistic regression analysis to screen and analyze laparotomy during laparoscopic cholecystectomy ,and its prognosis. Results 500 cases of cholecys-tectomy patients were converted to laparotomy in a ratio of 4.2%. The independent risk factors contained BMI index,patients with history of abdominal surgery,patients with cholecystitis episodes,doctors clinical experience , patients with gallbladder wall thickness during laparoscopic cholecystectomy. Twenty-one patients undergone laparotomy during laparoscopic cholecystectomy without severe complications. Conclusion Before laparoscopic cholecystectomy,physicians should analyze the following factors comprehensively in obesity,abdominal surgery, recurrent cholecystitis,gallbladder wall thickness,in order to determine the operating method and reduce the the rate from laparoscopic cholecystectomy to laparotomy.

Based on the review of development course of interventional radiology in China during the period of more than twenty years, to analyse emphatically the main problems impeding the continuous development of interventional radiology, included the branch position of "Interventional Radiology" not be defined clearly in the medicines, the professional association not to do its best in the management and guidance, the professional quality of the personnel not to be properly trained, as well as the insufficiencies of foundation and experimental studies, etc. And in this paper, the corresponding countermeasures of solving those problems have been primarily explored by the authors, and pointed out as follows: to improve perfectly the branch construction of the "Interventional Radiology" and the training system of special personnel; to raise the grade and function of the professional association and periodical; to lay stress on the foundation and experimental studies; to further deepen the clinical study and correctly deal with the relation between this branch and the other clinical departments, etc.

Objective To explore the emotional socialization development between boys and girls aged 1-3 years. Methods A total of 1008 children were randomly selected with 571 boys and 437 girls. Chinese version of Urban Infant-Toddler Social and Emotional Assess-ment (CITSEA) was used to assess the emotional socialization development situation between boys and girls. Results There were statistical-ly significant differences between boys and girls in the overt behavior domain and ability domain of CITSEA (t>2.136, P<0.05), and was not in the covert behavior domain and imbalance domain (t<1.172, P>0.05). Conclusion There are gender differences in emotional socialization development of children.

Objective To explore the repetitive expressions of autophagy marker protein-rnicrotubule-associ-ated protein 1 light chain 3 (LC3) in hippocampus in newborn rats with recurrent seizure and the influence of 3-methyladeine (3-MA) on LC2 expressions. Method Seventy-two 6-day-old SD rats were randomly (random nam-ber) divided into the recurrent neonatal seizure group (RS group, n = 24), the 3-MA-treated seizure group (3-MA group, n = 24) and control group (n = 24). Rats in RS group were subjected to 55 attacks of seizure induced by flurothyl in 9 successive days from the 6th postnatal day (P6). In 3-MA group, 2 μL of 3-MA was injected every day till seizure induced. Western blot analysis was used to determine LC3 protein level in hippocampus at different intervals of 1.5 h,3 h,6 h and 24 h after the last convulsion. The LC3 protein level was analyzed with Dunnett test after ANOVA. Results LC3 protein levels in RS group at the different intervals were significantly higher than those in the control group and in 3-MA group (F =4.70,5.28,8.51 and 5.89, respectively, P <0.05), and there were no significant differences in LC3 protein level between 3-MA group and control group at those intervals (P > 0.05). Conclusions The autophagy/lysosomal pathway is immediately activated after recurrent seizure evidenced by the elevated expressions of LC3 in hippocampus. The 3-MA is involved in the regulation of autophagy/ lysosomal pathway by down-regulating the expressions of LC3.

Objective To establish a rapid culture method for monitoring of influenza circulation and laboratory diagnosis of individual patients with influenza. Methods Nasal aspirate specimens were spun onto 24-well plate containing confluent monolayers of Madin-Darby Canine Kidney (MDCK) cells. Fluorescein labeled monoclonal antibodies to influenza A and B viruses were used to stain and type the isolates. Results A total of 713 nasal aspirates specimens from patients experiencing influenza-like symptoms was collected in Beijing between December of 2000 and March of 2001, 187(26 2%) specimens were found with influenza A virus and 109(15 3%) with influenza B virus. 2 2% with influenza A and 11 2% with influenza B virus were detected in 89 nasal aspirates specimens between Jan-Apr 2002. Conclusion Prevalence of influenza was low during 2000～2002 year non-epidemic period in Beijing. The combination of shell viral assay and direct immunofluorescent staining can provide a rapid laboratory diagnosis of influenza, which makes possible for the patients to receive treatment of anti-influenza virus drugs.

Objective To investigate the significance of Human papilloma virus(HPV)typing in the screening of cervical dis-ease.Methods 687 cases of gynecological patients in the hospital were enrolled in the study,whose HPV-DNA genotype was detec-ted by real-time fluorescence quantitative PCR(FQ-PCR).In addition to that,389 healthy women who took gynecological examina-tion in the hospital in the same period were enrolled in the study,HPV-DNA quantitative detection were performed on those people (FQ-PCR were used)firstly,and the persons with more than 5×102 IU/mL HPV-DNA were tested for the HPV-DNA subtype. Results In the 687 cases of gynecological patients,164 cases were HPV positive which accounted for 23.9%;The single-infection patients accounted for 74.3%,mixed infection accounted for 25.6%.The mixed infection included 2 -4 types of infection,among which the double infection was most common.The common type were HPV16,52,58 and 35.In 389 cases of healthy women,29 ca-ses were found HPV positive,which accounted for 7.5%;The single infection accounted for 79.3%,mixed infection accounted for 20.7%,mixed infection included 2-3 types of HPV infection,in which double infection is the most common situation.The common type were HPV52,58,16 and 18.Conclusion HPV infection is the major cause of cervical cancer,HPV detection and typing con-tribute to cervical cancer screening and its prevention.

Objective To study the effect of Gabapentin(GBP)on the transient receptor potential vanilloid l(TRPV1)in dorsal root ganglion (DRG)of rats with chronic constriction injury(CCI). Methods SD male rats were used to establish CCI model and randomly divided into 3 groups,the control group,the CCI group,and the CCI+GBP group. Mechanical allodynia and thermal hyperalgesia were measured to evaluate the es?tablishment of CCI model and the analgesic effect of GBP. At the postoperative 8 days,all rats were sacrificed and dorsal root ganglions were collect?ed for further RT?PCR and Western?blotting analysis to detect expression of TRVP1 in DRG. Results The mRNA and protein expression of TRPV1 were both significantly increased in DRG after CCI operation and GBP could decrease mRNA expression of TRPV1 gene in DRG after CCI. Conclusion The expression of TRPV1 was increased in DRG after CCI operation which was decreased after administration of GBP.

0.05). Conclusions Autop-hagy/lysosomal pathway was activated immediately after recurrent seizures as indicated by the elevated expression of Beclin1 in cerebral cortex. 3-MA was involved in the regulation of autophagy/lysosomal pathway by down-regulating the expression of Beclin1.
