Objective To investigate the efficacy of retroperitoneal laparoscopic heminephroureterectomy for duplex kidney anomalies.Methods Retroperitoneoscopic heminephroureterectomy was performed on nine patients, six males and three females.The average age of the study group was 37 years ( range 13 to 58).Seven cases had anomalies on the upper kidney pole, two cases had anomalies on the lower kidney pole.Five anomalies were on the left side, two were on the right side and two were in bilateral sides (one special case had three ureters on the left side and two ureters on the right side ).Three cases complained of flank pain; two cases were found hydronephrosis by physical routine examination;Three cases complained of flank pain and fever; one cases complained of hematuria and kidney atones.All the cases were preoperatively diagnosed by color doppler ultrasound, MRU, IVP or CTU.Retroperitoneal laparoscopic heminephroureterectomy was performed on all patients.The operation time, blood loss, hospital stay, intraoperative and postoperative complications and efficacy were observed.Results All the retroperitoneal laparoscopic procedures were successfully completed.No intraoperative complications were found.The average operation time was 87 min (range, 65 to 125).The average blood loss was 112 ml (range, 30 to 600).The recovery times of intestinal function was 1.6 days ( range, 1 to 3 ).The average postoperative hospital stay was 7 days (range, 5 to 12).The syndrome disappeared and kidney function was normal at a mean followup of 18 monthes.Conclusions Retroperitoneal laparoscopic surgeries for duplex kidney has the benefits of being minimally invasive, fewer complications, quick recovery and certainty of efficacy.Retroperitoneal laparoscopic surgeries can be considered as a first operation method to treat duplex kidney anomalies.

ObjectiveTo investigate the efficacy of transurethral resection and ball pouch dilatation for treatment of ureterostenosis.MethodsThe clinical data of 49 cases of ureteral stricture were analyzed retrospective analysis from June 2008 to June 2011 with 20 cases of male patients and 29 cases of female patients.The age was 15 to 56 years,with a mean age of 40 years.Ipsilateral renal function were mild impairment in 4 cases,moderate impairment in 35 cases,and severe damage in 10 cases.There were ureteropelvic junction etenosis in 11 cases,upper ureteral stricture in 13 cases,and lower segment stenosis in 25 cases.The ureteral stricture length was 0.3 to 2.0 cm,with a mean of 1.2 cm.Seventeen patients were treated with transurethral resection and ball pouch dilatation by minimally invasive percutaneous nephrostomy,and 31 cases were completed by ureteroscopy.The ureteral stents were removed by ureteroscope after 3 - 6 months.45 cases were followed up for 12 -43 months,with a mean of 24 months. ResultsForty-eight cases were completed smoothly with 1 case converted to open surgery.The surgical time was 25 to 95 min with a mean of 42 min.The postoperative hospital stay was 2 to 6 d with a mean of 4 d.In the follow-up of 45 cases,B ultrasound and CT scan showed hydronephrosis reduced significantly in 39 patients,IVU showed unobstructed ureter without significant stenosis.And 6 cases showed no significant changes in hydronephrosis. Conc(t)usionThe method of transurethral resection and ball pouch dilatation has good clinical effect,less pain and shorter hospital stays,which provides a new and effective treatment for patients with ureteral stricture.

Objective To explore the clinical utility of fluorescence in situ hybridization (FISH) urine test as a non-invasive method for diagnosing the upper urinary tract urothelial carcinoma (UUTUC).Methods Urine specimens from 30 consecutive patients with UUTUC were analyzed by means of FISH and cytology.Ultrasonic and CT were also used to analyze urine specimens from the study group.Urine specimens from 30 patients with other diseases were also analyzed by means of FISH and cytology in order to compare the specificity.Results The sensitivities of FISH,cytology,CT and ultrasonic were 87％,37％,90％ and 43％.The specificity of FISH and cytology were 97％ and 93％.The sensitivity between FISH and MMCT were compared and they were not statistically significantly superior to ultrasonic and cytology.FISH and cytology were compared and no specific statistical significance was found.The positive and negative predictive value for FISH was 96％ and 88％.For cytology it was 85％ and 60％.Conclusions FISH analysis is a useful ancillary test in the detection of UT-TCC with excellent sensitivity and specificity.It provides a more reliable and less invasive approach to diagnosis and postoperative follow-up for UT-TCC.

Approach-avoidance conflict(AAC)refers to the internal conflict that individuals experi-ence when faced with conflicting approach or avoidance thoughts.It reveals some characteristics of mental disorders,such as anxiety,depression,and addiction represented by excessive tendencies of approach or avoidance.The function of the cortico-limbic-striatal system influences behavioral choices at the neural level during the onset of AAC,and the development of related behavioral paradigms that can better represent AAC behaviors is critical to evaluating the efficacy of drugs and guiding the development of new drugs.This paper summarizes the neural mechanisms,behavioral paradigms,and applications in behavioral pharmacology related to AAC behaviors from the perspective of psychopharmacology with a view to providing new perspectives and methods for the diagnosis and treatment of related neuro-psychiatric disorders.

OBJECTIVE To explore the distribution pattern of traditional Chinese medicine(TCM)syndrome types of primary o-varian insufficiency(POI)sleep disorders and the differences in the distribution of sleep quality index among different syndrome types,in order to provide a basis for syndrome differentiation treatment and prevention of POI associated with sleep disorders.METHODS 600 POI patients who met the inclusion criteria were collected for epidemiological investigation,and 405 patients who met the diagnosis of sleep disorders were selected as the research group.The patients'general information,TCM four diagnosis and sex hormone level in-formation were collected,and the Pittsburgh sleep quality index(PSQI)scale was used to evaluate patients'sleep conditions,and ana-lyze the characteristics and influencing factors of TCM syndrome types of POI associated with sleep disorders.RESULTS The main TCM syndrome types of POI accompanied by sleep disorders were heart and kidney disharmony syndrome(41.98%),spleen and kid-ney yang deficiency syndrome(22.22%),kidney deficiency and liver stagnation syndrome(20.99%),and kidney deficiency and blood stasis syndrome(14.81%).The heart and kidney disharmony syndrome had the longest sleep latency and shortest sleep time,relied more on hypnotic drugs,and had the highest PSQI total score;the heart and kidney disharmony syndrome and kidney deficiency and liver stagnation syndrome had the worst sleep quality;the spleen kidney yang deficiency syndrome had the highest daytime dysfunc-tion score.There was no significant difference in FSH levels among different TCM syndrome types;the distribution of E2 values from low to high was:heart and kidney disharmony syndrome,kidney deficiency and liver stagnation syndrome,spleen and kidney yang de-ficiency syndrome,and kidney deficiency and blood stasis syndrome,and there were significant differences among multiple groups(P<0.05).CONCLUSION The main TCM syndrome types of patients with POI and sleep disorders are heart and kidney disharmony syn-drome,spleen and kidney yang deficiency syndrome,kidney deficiency and liver stagnation syndrome,and kidney deficiency and blood stasis syndrome.Among them,the most common TCM syndrome type with the worst sleep quality is heart and kidney disharmony syn-drome,which may be closely related to estrogen E2 levels.

Animal models are powerful tools for studying the mechanism of depressive disorders and screening antidepressants,but so far there is no model which can stimulate the clinical status of patients ideally.Here,we briefly introduced the research advances in classic animal models of depres-sive disorders,and focused on stress-related animal models,especially those induced by physical and social psychological stressors.The tests for evaluating animal depression behavior were reviewed.In this article,the strengths and weaknesses of each model were analyzed,and the precautions in its application were recommended.Finally,given the high heterogeneity of depressive disorders,this article elaborated on the research progress in models for subtypes of depressive disorders,such as treatment resistant depression,bipolar disorder,peripartum depression,and premenstrual syndrome.

[Objective]To discuss the causes of coronary heart disease with depression and other body and spirit diseases,which are related to river water,and propose the corresponding treatment methods.[Methods]By using the method of image thinking,this paper links the transformation of cloud and rain with the Qi and blood of human body,which is the common cause of body and spirit diseases.At the same time,this paper links the cause of coronary heart disease with depression with river water,and treats the disease with the method of treating water.[Results]The transformation between clouds and rain in nature is similar to the transformation of Qi and blood in the human body.Qi and blood come from the same source and affect each other,and Qi and blood remain smooth,so as not to cause physical and mental diseases.The root cause of coronary heart disease with depression is that Qi and blood are not smooth,and a series of lesions they produce are similar to the blockage of the river,so it is necessary to regulate Qi and blood according to the different stages of the disease,with the method of strengthening the spleen,promoting blood circulation,detoxification and opening depression.[Conclusion]Inspiring ideas through the analogy of image thinking can correctly understand and treat coronary heart disease with depression,which is also the purpose of image thinking.

Objective: : To investigate the relationship between the expression of RUNX1 isoforms and the clinical curative effect and the prognosis of acute leukemia (AL), in order to provide valuable experimental data for the individualized treatment, MRD (minimal residual disease) monitoring and prognosis prediction of AL. Methods: AL patients with primary treatment (PT, n=88) and recrudescence (RC, n=10) that treated at the Department of Hematology of Affiliated Hospital of Guangdong Medical University from April, 2012 to April, 2013 were included in this study. Real-time PCR was used to examine the mRNA expression of RUNX1 isoforms (RUNX1a and RUNX1b/c) in PT patients, RC patients and controls (non-malignant hematological disease patients).The changes in mRNA expression of RUNX1a and RUNX1b/c in patients before and after the chemotherapy were also observed. Results： ： (1)The expression levels of RUNX1a mRNAinAML andALL PT group andAML RC group was significantly higher than those of control group (P<0.05); The expression level of RUNX1a mRNAinAMLPT group was increased compared withALLPT group (P<0.05). (2) The expression levels of RUNX1a and RUNX1b/c mRNAinAML andALL patients at initial treatment were significantly higher than those after complete remission (CR) (P<0.05). (3) By comparing the expression levels of RUNX1a and RUNX1b/c mRNA at initial diagnosis, there was no significant difference between 6-month death group and survival group, CR group and NCR (non-complete remission) group after first cycle of chemotherapy, or the high leukocyte group and non-high leukocyte group (all P>0.05).The expression level of RUNX1a mRNA in AML-ETO positive group was higher than that of negative group (P<0.05). (4) The expression levels of RUNX1a and RUNX1b/c mRNA in patients with acute leukemia decreased with the increasing chemotherapy cycle, and significantly increased when had a relapse, which may even succeed the initial level.Conclusion: RUNX1a isoforms participate in the pathogenesis of acute leukemia, and isrelated to the relapse ofAML. The expression levels of RUNX1a and RUNX1b/c mRNAare related to the clinical efficacy that can be used as an indicator of curative effect, but have no significant correlation with the prognosis of the disease.Dynamic monitor of theexpression levels of RUNX1a and RUNX1b/c isomers can be used as an effective indicator of MRD monitoring after chemotherapy, which can be used to evaluate the efficacy and identify the risk of recurrence at early stage.
