Objective To evaluate modified retroperitoneal laparoscopic resection of renal cyst. Method Thirty-six patients with renal cyst were treated by modified retroperitoneal laparoscopic resection of renal cyst,summarized the clinic data and follow-up the effect. Results All 36 cases were operated suc-cessfuUy without changing to opening operation,average operation time (50 ± 35)min,no complications oc-curred and no recurrence was found. Conclusions The modified retroperitoneal laparoscopic resection of renal cyst with two 5 mm-trocars and one 10 mm-trocar has less trauma than classic laparoscopic operation. It is one of mini-trauma operation method which is worth to be popularized in clinic.

AIM: To investigate the effect of mfn2 on mitochondrial function in steatosis hepatocytes. METHODS: Plasmid pEGFP-mfn2 was transfected into hepatocyte strain L02 by Lipofectamine 2000 in vitro, then the steatosis model of hepatocytes was establish by oleic acid induction. RT-PCR was used to evaluate mRNA expression and Western blotting was use to detect the protein expression. ATP level was determined by firefly luciferase bioluminescent. ROS production was measured by fluorescence probe DCFH-DA. Chondrosome transmembrane potential of L02 was observed by labeling of JC-1 and FCM. RESULTS: The stable expression of ectogenesis mitofusin2 in L02 cells was confirmed by RT-PCR and Western blotting. In the model of oleic acids induced lipid formation, Mfn2 obviously inhibited the descent of chondrosome transmembrane potential and ATP level, and increased ROS production in L02 cells. CONCLUSION: Up-regulated expression of mfn2 attenuates mitochondria dysfunction caused by oleic acids induced lipid formation.

Objective To explore the application ways of IHE XDS technology in electronic medical record (EMR) system and develop application system of clinical EMR integration. Methods The clinical EMR integration plan was worked out based on IHE XDS technical framework. Results A EMR solution based on IHE XDS was presented. It was consisted of the components of the clinical Data Entry, XDS Registry, clinical document Repository, EMR application server and the i-node accessing server. The system was tested and the result indicated that the system was effective and scalable. Conclusion IHE XDS profile can be not only used to realize the sharing of EMR documents across multiple hospital, but also support the collection clinical data within a hospital clinical system integration.

ObjectiveTo examine the effects of proprioceptive neuromuscular facilitation(PNF) techniques on lower limb motor function of strokes and its mechanism.MethodsWe used simple random sampling and cross-section survey design. PNF Contract Relax Agonist Contract(PNF-CRAC) techniques were applied to 44 stroke patients. Surface electromyography values(sEMG) was recorded from rectus femoris and hamstring of stroke patients with both low limbs. ResultsPNF-CRAC techniques not only caused the irradiation of muscles activities in the contralateral extremity during unilateral exercise, but also increased agonist EMG activities and the motor control of knee joint in strokes.ConclusionPNF-CRAC techniques can improve the knee stability and enhance the recovery of motor function in paretic lower limb.

This review summarized the research status on DNA molecular identification of plants in the genus Chrysanthemum. Some case studies on representative DNA molecular identification techniques, which included ge-nomic in situ hybridization (GISH), DNA molecular markers and DNA barcoding, were described. Simultaneously, the merits, demerits and development of the techniques were discussed. The above work provides evidence for the identi-fication and resource utilization of plants in the genus Chrysanthemum.

Objective:To investigate the expression and clinical significance of wild-type p53-induced phosphatase 1 (Wip1) in thyroid carcinoma and biological effect of siRNA-targeting Wip1 on the thyroid carcinoma cell line. Methods:Immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR) were performed to detect the expression of Wip1 in 73 specimens of thy-roid carcinoma tissues and normal thyroid tissues (5 cm away from the margin of thyroid carcinoma), respectively. Wip1 siRNA was transiently transfected into the papillary thyroid carcinoma cell by using a liposome-mediated method and then detected by RT-PCR and Western blot. Methyl thiazolyl tetrazolium (MTT) assay and flow cytometry (FCM) were also conducted to observe cell proliferation, cell apoptosis, and cell cycle. Results:The positive rates of Wip1 protein were 80.8%in thyroid carcinoma tissues and 9.6%in the nor-mal tissues (χ2=47.036, P<0.05). The relative mRNA contents of Wip1 were 0.665 ± 0.046 and 0.225 ± 0.039 in carcinoma and normal tissues, respectively;these results significantly differed between the two types (t=12.637, P<0.05). Significant correlation was not ob-served between Wip1 expression and other factors, such as patient's gender, age, and tumor size (P>0.05). However, significant correla-tions among Wip1 expression, lymph node metastasis, clinical stages and tumor differentiation (P<0.05) were observed. RT-PCR and Western blot results showed that K1 cell-transfected Wip1 siRNA exhibited a relatively lower expression than normal cells (t=17.039, t=14.637, P<0.05). MTT assay results showed that the K1 cells transfected with Wip1 siRNA showed a lower survival fraction, higher cell apoptosis, higher percentage of G0/G1 phases, and lower cell concentration in G2/M and S phases (P<0.05). Conclusion:Wip1 pro-tein and mRNA were increased in thyroid carcinoma and are correlated with lymph node metastasis, clinical stages and tumor differenti-ation. Wip1 may be involved in proliferation, apoptosis, and cycle of thyroid cancer cells.

Objective To evaluate ultrasonography combined with magnetic resonance imaging(MRI) diagnosis value for fetal brain deformities.Methods The results of ultrasonography and MRI was analysied in 12 fetuses with deformities,which were compared to postnatal,autopsy or other hospital inspection results and evaluated the accuracy.Results In 8 cases,the diagnoses established by ultrasonography were correct.3 cases were misdiagnosed by ultrasonography,1 case was missed the diagnosis.In 11 cases,the diagnoses established by MRI were correct and 1 case was missed the diagnosis.Conclusion Ultrasonography must be choosed in diagnosising fetal skull brain deformities,MRI was supplement to ultrasonography in complicated pregnancies.The combination of ultrasonography and MRI have an important value in guiding pregnant women to determine whether or not to continue the pregnancy.

Objective To investigate the changes of the N-acetylaspartate(NAA) concentrations in different brain regions and executive function skills in alcohol dependence,and to study the relationship between NAA levels and cognitive functions in subjects.Methods 49 male,non-smoking,alcohol-dependent patients and 45 healthy control subjects were measured with Proton 1H Magnetic resonance spectroscopy (MRS) and Wisconsin Card Sorting Test (WCST).Results Alcoholics had lower NAA/Cr ratios in prefrontal grey matter(GM) (1.59± 0.13) and white matter(WM) (1.58±0.12) regions and performed poorly on executive function tests compared to controls (P＜0.001).NAA/Cr in left prefrontal regions positively correlated with certain parameters of EF testing (number of correct responses 30.37± 3.73,perseverative errors 11.49± 3.39,random errors 6.18± 2.64,categories completed 2.08± 1.59)in alcoholic group (P＜0.01).NAA/Cr in prefrontal WM regions correlated with certain parameters of EF testing in alcoholic group (number of correct responses r=0.379,categories completed r=0.433,P＜ 0.05).Conclusion Long-term,chronic alcoholism will damage neuronal viability and cognitive functions,which suggests that NAA concentrations can reflect the extent of damage of cognitive functions with decreased levels reflecting neuronal loss.
