Objective: To develop parental punishment style the questionnaire. Methods: Based upon previous literature about parental punishment style and expert interview, data were collected for the parental punishment style questionnaire. A sample of 1028 junior high school students were asked to complete the questionnaire and 158 of them was given retest after a month. Results: Taken from the questionnaire by exploratory factor analysis four factors were compatible. The results of confirmatory factor analysis showed a good fit to the data. The internal consistency reliability of father and mother questionnaire was satisfactory, with Cronbach ? coefficient 0.91; and the test-retest reliability was also satisfactory, with test-retest correlation coefficient 0.88 and 0.89, which showed good content validity and high construct validity. Conclusion: The questionnaire has good reliability and validity, and meets the need of psychometrics.

Objective To investigate the clinical characteristics of hypertrophic cardiomyopathy (HCM) in the elderly. Methods The clinical characters of HCM in 70 elderly patients were retrospectively analysed. Results Among the 196 identified HCM patients, 70 were elders. Out of them, 7 patients(10.0%) were suspected as HCM according to the clinical symptoms, 29 patients (41.4%)were suspected as other cardiac diseases, 34 (48.3%) were diagnosed HCM due to other reasons. Among the 70 patients, 12 patients(17.1%) had history of cerebrovascular diseases, 54 (77.1%) manifested symptoms after 45 years of age and 4 (5.7%) showed no obvious symptoms. Among them, 18 patients were examined by UCG for two times and HCM was diagnosed at the second time. Conclusions HCM in the elderly is not an uncommon disease. The onset of cardiac symptoms is relatively late in the elderly HCM and frequently misdiagnosed; cerebrovascular diseases are commonly seen in elderly HCM patients.

Data is the basis and soul of clinical trials. To obtain accurate data, strict and standard data management is essential, which can be effectively supported by quality control in statistical analysis. In this paper, we briefly introduce the concept of the quality control in clinical trials, and describe its contents and methods. We hope that this work will be helpful to the application of statistical quality control in data management of clinical trials.

Objective To evaluate the stability of dipstick dye immunoassay (DDIA) kit forschisitosomiasis diagnosis. Methods By means of detection of the sera from infected people withSchistosoma japonicum and healthy people, the stability of the DDIA kit, which stored at 37℃,room temperature or 4 ℃ respectively, was evaluated depending on the detective results ofsensitivity, specificity, detectable minimum and coefficient variation ( CV). Results Thesensitivity, specificity, detectable minimum and coefficient variation of the DDIA kit were invariableafter the kits stored at 37 ℃ for 180 days, and at room temperature or 4 ℃ for 360 days.Conclusion The DDIA kit is stable while it stores at 37℃ for 180 days, and at room temperatureor 4℃ for 360 days at least.

Objective To investigate the clinical features and genetic basis of cryopyrin-associated periodic syndrome (CAPS). Methods The clinical manifestations, laboratory tests, and genetic tests of one case of CAPS were retrospectively analyzed. The related literatures were reviewed. Results A 7 year and eight month old male patient had recurrent fever for 7 years and his whole body was covered with patchy red rash which was itchy and faded with pressure. The limbs and joints were normal. The levels of high-sensitivity C-reactive protein, erythrocyte sedimentation rate, rheumatoid factors were increased. The patient had fundus arteriosclerosis, double conjunctival lesions and nerve deafness on both sides. There was no mutation found in NLRP3 gene coding region, but a heterozygous mutation (-2667G>T) had been found in 5 ' untranslated region. Compared with normal control, the mRNA level of NLRP3 increased 4.2 times and the expressions of IL-1βand IL-18 gene increased 2.2 (P=0.002) and 1.2 times (P>0.05). Conclusions The clinical features of CAPS can be recurrent fever, rash, and joint involved. The oph-thalmologic abnormalities and varying degrees of deafness may occur during the progression. The test of NLRP3 gene may help diagnosis.

Objective To study the effect of low-dose FK778 in preventing chronic renal al- lograft rejection in rats.Methods The rat model of chronic renal allograft rejection was established by using micro-surgery technique.The recipients were divided into two groups.The recipients in the study group were treated with FK778 at a dose of 5mg?kg~(-1)?d~(-1)dissolved in carboxymethylcellulose by means of gavage and the controls were treated with carboxymethylcellulose.Urinary protein con- centrations were measured every 4 weeks for 24 weeks.On 24th week after operation,the rats were killed and the kidney grafts were taken out for histological and immunohistological examinations as well as quantitative real-time RT-PCR analysis.Results After 24 weeks of treatment,proteinuria, the severity of chronic rejection,glomeruIosclerosicytes and monocytes/macrophages in the study group were significantly milder than in control group.And the expression of TGF-?mRNA and PDGF-B mRNA was significantly reduced in the study group as compared with that in the control group.Conclusion Low-dose of FK778 might prevent the rats from chronic renal allograft rejection.

Objective To investigate the mechanism of regulating gastrointestinal motility by elec- troacupunturing point of"Zusanli"in rabbits.Methods Thirty adult rabbits were divided into control, electrical acupuncture point of"Zusanli"and non acupuncture point groups.The blood concentrations of motilin were detected at different times(before acupuncture and 15,30,45 and 60 min after acupunc- ture).Sixty min after acupuncture,the mice were sacrificed.The acetylcholine esterase and nitric oxide synthase(NOS)in gastric and jejunum tissues were examined.The electron microscope was used to observe the vesicles of nerve ending.Results The concentrations of motilin in electrical acupuncture group was significantly increased and reached the high peak at 45min.The activities of acetylcholine es- terase was increased significantly in electrical acupuncture group compared to control group[gastric tis- sue:(15 571?2876)pinel vs(9081?801)pinel,P

Objective To assess the feasibility and efficacy of robot-assisted laparoscopic simple prostatectomy (RALSP) for the treatment of benign prostatic hyperplasia (BPH) with large prostate.Methods From January 2014 to July 2015,16 patients with large prostate (≥80 ml) were treated by RALSP.The average patient's age was 69 years.The prostate volume was (98.3 ± 12.9) ml,preoperative residual urine was (78.0 ± 24.8) ml,the average IPSS was (22.9 ± 5.9),the average QOL was (4.8 ±1.5) and the average Qmax was (8.9 ± 3.7) ml/s,respectively.All patients agreed to accept RASP.The pre-operative and three months post-operative IPSS,QOL,residual urine and Qmax were compared and analyzed.Results All 16 patients underwent the surgeries uneventfully.The average operation time was (92.5 ± 15.5) minutes,the estimated blood loss was (125.5 ±25.5) ml,drainage time was (4.6 ±0.8)days,catheterization time was (7.9 ± 1.2) days and postoperative hospital stay was (5.1 ± 1.1) days.Three months after surgery,patient's IPSS was (11.8 ± 3.1),QOL was (1.6 ± 0.9),the average residual urine was (12.3 ± 2.6) ml and Qmax was (29.4 ± 11.6) ml/s,respectively.All the parameters significantly improved compared with the preoperative data (P ＜ 0.05).Conclusions Robot-assisted laparoscopic simple prostatectomy is a safe and effective method for the treatment of BPH patients with prostate volume larger than 80 ml.

AIM:To investigate the cytological basis and differentiating conditions of human bone marrowmes-enchymal stem cells(hMSCs) differentiated into cells of the endothelial lineagein vitro.METHODS:hMSCs were isolatedby density gradient centrifugation and fractionated on a 1 073 g/L Percoll.The combination of VEGF165and various matrixproteins including fibronectin(FN) and typeⅠ collagen(Col) was used to induce hMSCsin vitro.Cells were character-ized by immunohistochemistry,cytochemistry,FACS and ultrastructure to identify and detect the differentiated populationand markers.RESULTS:hMSCs was positive for KDR.PAS reaction was positive and ultrastructure of hMSCs showedglycogen-pool in ectoplasm.Glycogen reducing or disappear suggested that stem cells have occurred differentiation.In-duction of hMSCs resulted in the increase of KDR,?1integrin and CD34.CONCLUSION:hMSCs were induced to atransit population(TP) that differentiated toward the endothelial progenitor cells(EPC),but not a really EPC.hMSCspedigree diagram of differentiation was hMSCs→TP→EPC→endothelial cells(ECs).
