Objective To evaluated the role of transurethral plasmakinetic resection of the prostate ( TUPKRP ) in combination with percutaneous bladder channel lithotripsy with holmium laser in the treatment of benign prostate hyperplasia ( BPH) and bladder stone in senior patients . Methods Seventy-three patients treated during January 2009 to May 2014 were retrospectively reviewed.The patients aged 70-95 years old (mean, 85.6 years old).All of the patients were complicated with one or more diseases of the cardiovascular system .Ultrasound examinations prior to operation showed the sizes of prostates ranging 35-105 g, among which 58 cases showed middle prostatic lobe protruding into the bladder cavity .The sizes of the bladder stones ranged 1.5 -4.5 cm. Results The operations were successful in all the cases .The time of lithotripsy ranged 15-50 min (mean, 24 min), and the time of prostatectomy ranged 40 -135 min (mean, 70 min).No severe complications, such as major bleeding, transurethral resection syndrome, bladder perforation, residual stones, or severe infections, were observed.The urethral catheters were removed 3-5 days after operation, without urine leakage, dysuria, or urinary incontinence.Post-operation pathology of all the cases revealed BPH .The duration of hospitalization was 5-10 d (mean, 6 d).Three months after operation, the international prostate symptom scores were decreased from (23.5 ±5.1) points to (7.5 ±1.6) points (P<0.05), the quality of life (QOL) scores were decreased from (5.1 ± 0.5) points to (2.2 ±0.8) poins (P<0.05), the maximum flow rates (Qmax) were increased from (6.2 ±2.4) ml/s to (17.9 ± 4.2) ml/s (P<0.05), and residual urine volumes were decreased from (185.6 ±29.7) ml to (30.0 ±21.2) ml (P<0.05). Conclusion Transurethral plasmakinetic resection of the prostate in combination with percutaneous bladder channel lithotripsy with holmium laser is safe and effective for the treatment of benign prostate hyperplasia and bladder stone in senior patients .

Objective To study whether the early continuous passive motion (CPM) can prevent the degeneration of articulation after the articular cartilage was experimentally defected, and the effect of the different durations of continuous passive motion therapy. Methods Fifteen New Zealand rabbits were used to establish the model of full-thickness defects of bilateral knee articular cartilage by operation. Then all the animals were divided into groups A, B and C: Group A served as the control group, and groups B and C served as the observation groups and were administered with 2 hours of continuous passive motion a day (group B) and 8 hours of continuous passive motion a day, respectively. All rabbits were sacrificed at the 12th week after operation, and their articular cartilage were observed. The cartilage and synovium were obtained to have the hematoxylin and eosin stain and immunohistochemistry stain. After that, the pathological assessment and calculation of the ratio of MMP-3 positive cells were conducted and compared among groups. Results Group C was lower than groups A and B in terms of the scores with cartilage pathological assessment and the ratio of MMP-3 positive cells(P

Objective To investigate neural correlates of the generation,execution and inhibition of motor intention. Methods Behavioral performance and event-related potentials (ERP) of 14 participants were recorded when they performed a two-staged Go-Nogo task. At the stage of intention preparation,three kinds of the "what" cues were presented separately to the participants : (1) to press a response key by the left or the right hand (the instructed) ,(2) to decide freely which hand will be used (the free) ,(3) to wait for the second cue (the control). At the stage of intention execution,the "whether" cue suggested the participants execute (Go) or withdraw (Nogo) the previous intention either voluntarily or forcedly. Results The interaction effect between the "what" and the "whether" was significant(F(2,26) = 8.262, P=0.002). The forced responses were faster than those of voluntary action under both the instructed condition ((468.52 ±105.87)ms vs (546.67 ±146.33)ms) and the control condition ((536.78 ± 83.28) ms vs (589.75 ± 140.80) ms). No significant difference was found for the free condition((538.71 ± 127. 39) ms vs (561. 44 ± 146. 51) ms). At the stage of intention preparation,significant ERP effects between the instructed intention and the freely intention were revealed in bilateral frontal regions (150～200 ms) , frontoparietal area (300～700 ms)and right temporal area. At the stage of intention execution,ERP effects between voluntary inhibition and voluntary action were observed in left prefrontal area (160～220 ms) ,fro-nto-cento-parietal area and right frontoparietal area. (300～550 ms). Conclusion The motor intention may be generated in the prefrontal area and maintained in the frontoparietal network. The left prefrontal and fronto-centro-parietal areas inhibit intention in the early stage and the right frontoparietal area involves response inhibition lately.

Objective To investigate neural correlates of the retrieval of temporal order.Methods ERP of 19 channels was recorded from 17 healthy young students while they performed a recency judgment task,a recognition task and a visual discrimination task separately,which were based on Sternberg paradigm.One-way ANOVA of repeated-measurement and post-hoc paired comparisons were carried out for both the task factor(temporal order,recognition and control)and the temporal distance factor correspondingly.The latter contains 3 intervals (1,2 and 3)between the targets.Results The temporal distance effect was significant:the closer targets correspond to longer reaction time((745.5±106.1)ms,(711.7±102.2)ms,(653.7±81.5)ms;F_((1.28,20.48))=43.37,P=0.00]and higher error rate((62.8±7.0)%,(72.5±5.4)%,(84.5±6.4)%;F_((1.32,21.11))=135.99,P=0.00].Significant behavioral effect of the task factor was also found for both reaction time(F_((1.32,21.11))=135.99,P=0.00)and error rate(F_((2,32))=200.31,P=0.00).No significant behavioral difference was found between the temporal order group and the recognition group.The spatiotemporal pattern of statistical parametric mapping(SPM)suggested the ERP effects of temporal order were presented in left temporal region (260～270 ms),bilateral parietal-occipital areas(280～290 ms),and bilateral parietal lobes(300～400 ms)prominently.No ERP effect was found between the temporal order task and the recognition task.Conclusions The neural correlates of the temporal distance effect exist in bilateral parietal regions.Temporal order as well as object information processing involves similar cerebral regions during the retrieval period.

Objective To analyze the chromosome karyotypes,prenatal diagnosis indications and pregnancy outcomes of high-risk pregnant women in Guangzhou.Methods 2 475 cases pregnant women with screening high risk were operated amniocen-tesis or cordocentesis from January 2010 to September 2012,then amniotic fluids and cord bloods were cultured and the cell were collected for chromosome preparation,G banding,karyotype analysis.We completed follow-up works lastly.Results 38 cases were detected chromosomal abnormality(including 12 cases Down′s syndrome,9 cases sex chromosome abnormality,7 cases transloca-tion,5 cases Edwards′syndrome,2 cases inversion,2 cases deletion,1 cases triploid),the abnormal rate was 1.54%.132 cases were detected chromosomal polymorphism(60 cases 1,9,16qh+ ,30 cases inv(9),25 cases D/Gs+ ,17 cases Y polymorphism).Research on prenatal diagnosis indications,there were 449 cases advanced age,668 cases Down′s screening with high risk,158 cases with ab-normal B ultrasound screening,38 cases with adverse pregnancy history.Conclusion The highest percentage abnormal karyotype is Down′s syndrome.Down′s screening high risk is the main reason for prenatal diagnosis.It is very important to do prenatal diagnos-tic and system B ultrasound for the high-risk pregnant women.

OBJECTIVE: To test the reliability and validity of Health Scale of Traditional Chinese Medicine (HSTCM) by means of questionnaires. METHODS: A cross-sectional survey was conducted at Liwan Community of Guangzhou, Old People's Home in Guangzhou and Outpatient Department of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine. A total of 652 Chinese individuals (over 18 years old) were assessed with the 88-item version of HSTCM and World Health Organization Quality of Life Measure-Abbreviated Version (WHOQOL-BREF), which were randomly delivered to them. Some socioeconomic characteristics were registered. RESULTS: A test-retest reliability (15-day interval) was found among the 76 persons who completed the questionnaires by themselves. Intra-class correlation coefficient (ICC) was 0.93. Associated 95% confidence interval (CI) was 0.89-0.96. Split-half reliability was 0.79. Inter-investigator reliability (0.93) was also good, and the ICC of HSTCM was 0.90 (95%CI 0.67-0.97). The correlation between HSTCM and WHOQOL-BREF was -0.66. The correlations of HSTCM and questionnaire deliver order, investigator, interview date and interview time were 0.06, -0.12, -0.17 and 0.20 respectively. The correlation between HSTCM and self-rated health (0.46) was greater than that between HSTCM and chronic illness (0.28). Divided by individuals with or without chronic illness, area under the ROC (receiver operator characteristic) curve for HSTCM was 0.67 (95%CI 0.63-0.71). CONCLUSION: It indicates that the HSTCM is conceptually valid with satisfactory psychometric properties and forms a basis for further applications in clinical research of traditional or integrative medicine.

Objective To explore the impact of four different anesthetic drugs commonly used in animal experi-ments on cardiovascular system in rats.Methods Electrocardiogram ( ECG) and blood pressure were dynamically recor-ded by a BioPac MP150 system after anesthesia.In addition, the blood glucose at different time points and hepatic func-tion, kidney function, cardiac enzymes and electrolytes at the end of the test were collected.Rusults Chloral hydrate caused severe ventricular arrhythmia.Isoflurane had inhibitory effect on the heart rate.Pentobarbital sodium induced a in-crease of ECG P wave.Urethane caused J point elevation of ECG.Blood pressure in the urethane-and pentobarbital sodi-um-treated groups were increased.Chloral hydrate caused CK to be raised, while isoflurane showed the opposite effect on CK and CKMB.Alanine aminotransferase and aspartate aminotransferase in the pentobarbitol sodium and isoflurane groups were decreased.Creatinine in the chloral hydrate, pentobarbital sodium and isoflurane groups were lower, and the serum sodium and potassium were decreased in the four groups.Conclusions Chloral hydrate has obvious effect on the cardio-vascular system, and is not suitable for animal studies on cardiovascular diseases.Pentobarbital sodium, urethane, isoflu-rane can be chosen for animal studies on cardiovascular diseases.

To select appropriate descriptors for responses of the Health Scale of Traditional Chinese Medicine (HSTCM).

This study was aimed to analyze the bioinformatics of proteomics of rat bone marrow mesenchymal stem cells (MSCs) intervened by active principle region of Yang-Xin Tong-Mai Formula (apr-YTF). The latest versions of bioinformatics tools including DAVID (http://david.abcc.ncifcrf.gov/) and GO (http://www.geneontology.org/) were combined to assign a precise function to rat bone marrow MSCs intervened by apr-YTF. KEGG and VISANT were assigned with a precise function to rat bone marrow MSCs intervened by apr-YTF. The results showed that a total of 102 biological processes were mainly involved, with 35 cellular components and 6 molecular functions. These proteins interacted in 3 signal transduction pathways. It was concluded that the following proteins and signal transduction pathways played an important role in the process of apr-YTF inducing BMSCs differentiation into cardiomyocytes. Presenilin-1 and Presenilin-2 were in the Notch signaling pathway. And syntaxin-4 protein was in soluble N-ethylmaleimide sensitive fusion protein attachment protein (SNARE). The apr-YTF played a role on MSCs from multiple sites, with multiple links through different biological processes. The bioinformatics of proteomics can predict action mechanism of traditional Chinese medicine (TCM) from the holism concept. The validation in combination with molecularbiology was a good way for TCM modernization.

Objective: To investigate nutritional quality of school lunch in some primary schools and middle schools in the Pearl River Delta, and to provide the scientific basis for improving the nutritional quality of students lunch and formulating scientific and effective interventions. Methods: Five-day lunch meal survey by chemical analysis were conducted, and students lunch at school were recorded by meal review in three age groups from 8 primary and middle schools in the Pear River Delat area. The energy and nutrient content were obtained and compared with the reference intake of dietary nutrients of student. Results: The average protein intake at lunch of all age groups had reached the recommended standard (80%-95%), the energy supply ratio of carbohydrate in the range of 38.3%-42.3%, the energy supply ratio of fat in 63% school meal exceeded the recommended standard. Vitamin A, vitamin B 1, vitamin B 2, calcium, iron and other nutrients were seriously inadequate; while sodium intake far exceeded the recommended standard. Conclusion The main nutrients of school lunch of primary and middle school in Pearl River Delta can basically meet the growth and development needs, but there are still some deficiency and unbalanced diet nutrient content which are lower than the recommended intake. It is recommended to strengthen nutrition education of catering enterprises and school to improve the scientific combination of diets.
