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 explore the correlation between phenotypes in female with X-linked Alport syndrome(XLAS) and X-inactivation of different tissues.Methods Thirty-six female diagnosed as XLAS were studied,and proteinuria was taken as a marker of the severity of clinical phenotypes.X-inactivation patterns were analyzed in peripheral blood cells of 36 XLAS female and in skin fibroblasts of 12 XLAS female.The X-inactivation analysis was performed by using Hpa Ⅱ predigestion of DNA followed by polymerase chain reaction(PCR) of the highly polymorphic CAG repeat of the androgen receptor gene.Results The average X-inactivation levels of the mutant allele decreased while the degree of proteinuria increased,so there was a negative correlation between the degree of proteinuria and the X-inactivation ratios of the mutant allele in blood cells(r=-0.543,P=0.002).However,there was no correlation between the degree of proteinuria and the X-inactivation ratios of the mutant allele in skin fibroblasts(r=-0.131,P=0.701).Conclusions X-inactivation ratios might explain partially the diverse phenotypes in XLAS female patients,which suggested that the prognosis of XLAS female might be predicted via analysis of the X-inactivation in peripheral blood cells.

Objective To comprehend the awareness rate and the implementation of risk factors related to Helicobacter pylori (HP) infection in families with children of Helicobacter pylori infection.To analyze the existing problems and formulate effective methods of health education.Methods Totally 558 families infected with HP were investigated with a self-designed structured questionnaire by call-back.Results 527 did not use separate eating tools,350 did not use independent tablewares,14 drank unboiled water,14 did not use bath appliances separately,7 used tooth glasses together,4 did not wash hands before eating and after toilet,no one had mouth-to-mouth feeding.248 children with HP sleeped with their family members and 246 family members used to have HP infections or stomach troubles.Conclusions The families with HP do not establish correct ways of separate eating,so the hospital need to develop multi-channel education.Most families with HP infected children have satisfactory health habits.Nearly half of the children with HP do not sleep in their own beds.Caregivers of children with HP infection should be the capital objects of health education.

Objective To evaluate the security and biocompatibility of a new kind of absorbable high-strength PDLLA-CPP composite, which is used for internal fracture fixation. Methods According to the national standard of the procedure of appraise in food security and toxicology, micronucleus test of bone marrow cell, spermatic aberration test, chromosomal aberration test, and teratogenic test were measured with IP maximal tolerance dose of maceration extract from PDLLA-CPP composites. Meanwhile, chondrocyte culture with PDLLA-CPP composite was used to evaluate the effect of PDLLA-CPP composite on cartilage cell proliferation. Results Micronucleus test of bone marrow cell, spermatic aberration test, chromosomal aberration test, and teratogenic test were not affected by IP maximal tolerance dose of PDLLA-CPP maceration extract. PDLLA-CPP composite also had no cytotoxicity on cartilage cell proliferation. Conclusion PDLLA-CPP is a new and safe medical material with good biocompatibility and absorbability.

Objective To investigate the effect of mechanical thrombectomy device Solitaire AB for the treatment of distal occlusion of the intracranial artery caused acute anterior circulation ischemic stroke. Methods The clinical data of 9 patients with arterial occlusion of distal anterior circulation treated by using the Solitaire AB thrombectomy device were analyzed retrospectively. Seven of them had M2 middle cerebral artery occlusion and 2 had A3 occlusion. Their clinical features,imaging data,treatment,and the results of 3-month clinical follow-up were analyzed. The effectiveness of treatment was evaluated through the recanalization rate after stent thrombectomy,the National Institutes of Health Stroke Scale (NIHSS)scores before and after treatment,the modified Rankin scale (mRS)scores,and the 3-month clinical follow-up results. The surgery-related complications and mortality of patients were used to evaluate the safety of the treatment. Results (1 )Of the 9 intracranial arterial occlusions,8 were recanalized successfully. The modified thrombolysis in cerebral infarction (mTICI)was 2b or grade 3. (2)The NIHSS score median 9. 5 (3. 0,15. 5)at discharge dropped significantly compared with 19. 0 (16. 0,22. 0)before procedure. (Z=2. 703,P=0. 007). No permanent complications related to operation occurred. Four of the recanalized patients had good prognosis (mRS 0-1)and 4 had disability (mRS 3-4 ). The mRS score of one non-recanalized patient was 4 at the 3 months follow-up. Conclusion The embolectomy effect is good whom using Solitaire AB device for acute occlusion occurred in the intracranial artery M2 or A3 segment. Its efficacy,safety,and indications still need to be further explored in a larger sample controlled trial.

Objective To explore the early diagnosis value of C‐reactive protein (CRP) and procalcitonin (PCT ) for bacterial in‐fectious pneumonia of children .Methods A total of 101 children with bacterial infectious pneumonia ,64 children with non‐bacterial infectious pneumonia and 73 children with non‐infectious disease were selected in bacterial infectious pneumonia group ,non‐bacterial infectious pneumonia group and non‐infectious disease group respectively .Serum PCT and CRP levels were measured before treat‐ment in the three groups .With sputum culture results as gold standard for the diagnosis of bacterial infectious pneumonia ,the sensi‐tivity ,specificity ,positive predictive value ,negative predictive value ,Youden index and diagnostic accuracy of PCT ,CRP ,PCT /CRP series test and parallel test were calculated for bacterial infectious pneumonia diagnosis .Results The levels of PCT and CRP of children in bacterial infectious pneumonia group were significant higher than those of children in non‐bacterial infectious pneumonia group and non‐infectious disease group(P < 0 .05) .The sensitivity ,specificity ,positive predictive value ,negative predictive value , Youden index and diagnostic accuracy of PCT ( ≥ 0 .5 ng/mL as the best intercept point) for bacterial infectious pneumonia diagno‐sis were 0 .743 ,0 .719 ,0 .806 ,0 .639 ,0 .461 and 0 .733 .And the same values for PCT /CRP series test were 0 .604 ,0 .875 ,0 .884 , 0 .583 ,0 .479 and 0 .709 respectively .All the values were higher than those of children in non‐bacterial infectious pneumonia group and non‐infectious disease group except sensitivity .Conclusion The combination of PCT and PCT /CRP series test is ideal method for early diagnosis of bacterial infectious pneumonia with high sensitivity and specificity .
