This study investigates whether kappa-opioid receptor and ORL1 receptor may interact to form a heterodimer. In immunofluorescence and co-immunoprecipitation experiments, differentially epitope-tagged receptors, colocalization and heterodimerization of kappa-opioid receptor and ORL1 receptor were used and examined in primary culturing rat neurons, Chinese hamster ovary (CHO) or human embryonic kidney 293 (HEK293) cells. The results show that fluorescence of both kappa-opioid receptor and ORL1 receptor were overlapping in primary culturing hippocampal and cortical neurons. Similarly in co-expressing CHO or HEK293 cells, HA-KOR and Myc-ORL1 were almost exclusively confined to the membranes, revealing extensive colocalization. When Flag-KOR and Myc-ORL1 were co-expressing in CHO cells, heterodimerization was identified to have the ability to co-immunoprecipitate ORL1-receptors with kappa-opioid receptor and vice versa. In the current study, further evidence was provided for the direct interaction of two subtypes of opioid receptors, kappa-opioid receptor and ORL1-receptor, to form the heterodimerization. The finding represents the novel pharmacological mechanism for modulation of opioid receptor function as well as diversity of G protein-coupled receptors.

Objective To evaluate the effect of standardized training and management of prenatal ultrasound screening on birth defects. Methods According to the degree of standardized training and management of prenatal ultrasound screening, the period from March 2004 to December 2009 were divided into three different management stages. Detection rate was applied to describe the prenatal ultrasound screening of 5199 birth defects cases delivered during the three different management stages. Accuracy rate was used to describe the ultrasonographic diagnosis made by staffs in 2009. SPSS 11.5 software was used to analyze the information of 707 staffs participated in the training and assessment activities from October 2007 to September 2009. Related factors of prenatal ultrasound operating skills of staffs were analyzed by comparing the distributing discrepancy of the different variables between qualified and unqualified group with Chi-square test. Results The detection rate of prenatal ultrasonographic screening on birth defects increased with the improvement of training and assessment methods, which was 32. 43% from March 2004 to September 2005,44.81% from October 2005 to September 2007 and 60. 71% from October 2007 to December 2009respectively. In 2009, 187 doctors were tested on abnormal ultrasound photographs identification. The accurate rates were 80. 0% for gastroschisis, 78. 8% for cleft clip, 75.8% for omphalocele, 71.8%for neural tube defects, 50. 0% for severe congenital heart diseases, 31.0% for acromicria, which were in similar sequence as the diagnostic rate identified by prenatal ultrasound in 2009. Among the staffs attending the prenatal ultrasound screening assessment, more had education background at least university level (52.8% vs 47.2%), more performed ≥50 ultrasound screenings per month (50. 5%vs 49.5 % ), more had been working on obstetric ultrasound over 3 yrs (52.5 % vs 47.5 %) and more had been trained in higher level of hospitals focused on prenatal diagnosis (64.7% vs 35.3%) in the qualified group than in the unqualified group. Conclusions Standardized training and management of prenatal ultrasonographic screening could effectively improve the diagnosis rate of birth defects.The quality of prenatal ultrasound screening is related to the staff's education background and whether they are engaged in the position.

Objective To establish analysis methods for fingerprint of Chuanxiong Rhizoma by HPLC.

The samples were clustered into 3 categories. Conclusion The method is simple, steady and repeatable. It provides a basis for the quality control and evaluation of Chuanxiong Rhizoma.

OBJECTIVETo investigate the therapeutics of complex calculi in solitary kidney, and to improve the effect and safety of treatment.

METHODSExperiences in the treatment of 42 patients were summarized. All patients were with mould or multiple calculi, 8 cases were complicated with ureter calculi, and 6 cases were hospitalized because of obstructive anuria. The patients with mould calculi received extracorporal shock wave lithotripsy (ESWL) prior to percutaneous nephrolithotomy (PCNL). While the patients with multiple calculi received PCNL prior to ESWL. Some cases were treated by lithotripsy.

RESULTSThirty-six cases (86%) were cured by ESWL combined with PCNL. Eleven cases received lithotripsy during PCNL. The 6 cases with obstructive anuria recovered in 12 hours after emergent ESWL or lithotripsy; 6 cases (14%) underwent open operation because of deformity or obstruction in renal pelvis and ureter; 2 cases have to keep nephrostomy because of repeated infection. Followed up 6-18 months, 38 cases (86%) keep good kidney function; 5 cases (14%) had renal insufficiency; 4 cases (11%) reoccurred calculi.

CONCLUSIONSThe therapeutics of ESWL combined with PCNL may clear complex calculi of solitary kidney effectively and safe. It is necessary to take emergent ESWL in renal obstructive calculi cases. And the patients with lower ureter obstructive calculi may take lithotripsy first. It is proper to choose open operation on the patients with deformity of renal pelvis or obstruction of ureter.

OBJECTIVETo evaluate and compare the efficiency and safety of laparoscopic surgery (LS) and open surgery (OS) in the treatment of colorectal carcinoma.

METHODSRandomized controlled trials on laparoscopic surgery and open surgery for colorectal carcinoma from January 2000 to October 2010 were searched in the databases of EMbase, PubMed, Cochrane Library, Sciencedirect, Springer, VIP, CNKI, CBMdisc. The methodological quality was assessed according to the standard of Cochrane systematic review. For homogeneous studies, RevMan5.0 software was used for meta-analysis.

RESULTSA total of 13 RCTs involving 4603 patients were included in this study, and among those 6 were multi-center randomized controlled trials. The meta-analysis showed that: the operation time of the LS group was longer than that of the OS group (WMD = 38.91, 95%CI: 33.89 - 43.93, P < 0.001), the blood loss (WMD = -138.14, 95%CI: -195.79 - -80.50, P < 0.001) and the length of hospital stay (WMD = 2.91, 95%CI: -4.65 - -1.17, P = 0.001) of the LS group was less than those in OS group. There was no significant differences between the two groups in the number of dissected lymph nodes (WMD = -0.62, 95%CI: -1.47 - 0.23, P = 0.150). There was no significant differences between the two groups in terms of the postoperative complications (30 days) (RR = 0.78, 95%CI: 0.59 - 1.01, P = 0.06). There was no significant differences between the two groups in 3-year overall survival (RR = 1.00, 95%CI: 0.96 - 1.04, P = 0.970). There was no significant differences between the two groups in 5-year overall survival (RR = 1.03, 95%CI: 0.99 - 1.08, P = 0.140). There was no significant differences between the two groups in 5-year overall recurrence (RR = 0.89, 95%CI: 0.74 - 1.07, P = 0.200).

CONCLUSIONSLaparoscopic surgery for colorectal carcinoma is a safe and effective therapy as open surgery in the short term or long term outcomes. It could be an acceptable alternative to open surgery for colorectal carcinoma.

Thienorphine is a chemically-new opioid developed in Beijing Institute of Pharmacology and Toxicology. To elucidate the chemical basis for the unique pharmacological effects of thienorphine, 15 derivatives were synthesized according to combinatorial chemistry and the structure-activity relationships of these compounds were studied. It is demonstrated that thienorphine is a potent long-acting partial agonist. N-Cyclopropylmethyl is responsible for the antagonist effect of thienorphine. More importantly, thiophene at the end of side chain is most likely the pharmacophore accounts for the long-lasting effect of thienorphine. Change of the connection of thiophene and the side chain does not result in changes in the antinociceptive activity.

OBJECTIVETo develop a method to construct a three-dimensional finite element model of the dentulous mandibular body of a normal person.

METHODSA series of pictures with the interval of 0.1 mm were taken by CT scanning. After extracting the coordinates of key points of some pictures by the procedure, we used a C program to process the useful data, and constructed a platform of the three-dimensional finite element model of the dentulous mandibular body with the Ansys software for finite element analysis.

RESULTSThe experimental results showed that the platform of the three-dimensional finite element model of the dentulous mandibular body was more accurate and applicable. The exact three-dimensional shape of model was well constructed, and each part of this model, such as one single tooth, can be deleted, which can be used to emulate various tooth-loss clinical cases.

CONCLUSIONThe three-dimensional finite element model is constructed with life-like shapes of dental cusps. Each part of this model can be easily removed. In conclusion, this experiment provides a good platform of biomechanical analysis on various tooth-loss clinical cases.
