Objective: By taking the holism and differentiation concepts of traditional Chinese medicine (TCM) as the guidance, physical, mental and workplace factors were recruited in the observation of depression in employees, and were systematically classified to establish a workplace-related Liver Meridian-depression scale, for providing an evaluation index for depression in employees. Methods: NVIVO 11 software was adopted to assort ancient TCM classics. Based on the holism and differentiation concepts of TCM and well-developed scales, the item pool was determined via brain storm and screened by Delphi method after classified; a Wechat questionnaire was handed out 240 times via the online system 'Wen Juan Xing', and the results were statistically analyzed by the SPSS 17.0 version software. Results: Five dimensions consisting of 80 items were obtained after classification, and 60 items were selected by Delphi method; a total of 216 questionnaires were returned and the return rate was 90%. Of which, 215 questionnaires were valid ones, and the valid rate was 99%. By exploratory factor analysis (EFA), 44 items were obtained, and the aggregate split-half reliability coefficient was 0.922. The Cronbach's alpha coefficient for the five dimensions, i.e. Liver Meridian, relevant meridians, basic psychological activities, work cognition and emotional reactions, was respectively 0.841, 0.842, 0.914, 0.836 and 0.839, indicating a content internal consistency. The score of each item was highly correlated with the corresponding dimension, and the intercommunity was between 0.474 and 0.801. Nine factors were generated, 2 in the dimension of Liver Meridian, 3 in the dimension of relevant meridians, 2 in the dimension of basic psychological activities, 1 in the dimension of work cognition, and 1 in the dimension of emotional reactions, and the load of each factor was between 0.438 and 0.859. The reliability and validity of the scale were well examined. Conclusion: The scale can be applied to evaluate the qi activities of Liver Meridian and depression symptoms related to workplace.

Objective:To explore the relation between parental cohesion,peer acceptance and the loneliness of left-behind children,and furthermore explore the mediation role of self-esteem.Methods:Totally 427 left-behind children in Hubei Province (275 males,152 females) were surveyed,and the Parental Cohesion Scale (PCS),Peer Nomination (PN),Self-Esteem Scale (SES) and Children Loneliness Scale (CLS) were used to assess parental cohesion,peer acceptance,self-esteem and loneliness respectively.The relation between parental cohesion,peer acceptance andthe loneliness of left-behind children,and the mediation role of self-esteem wereanalyzed.Results:The CLS scores in left-behind children were negatively correlated with the scores of PCS,PN,and SES (r =-0.31,-0.37,-0.50,P ＜ 0.01),the SES scoresplayed a mediation role in the relation between PN scores and CLS scores (95 ％ CI:-7.02--0.01),and between PCS scores and CLS scores (95 ％ CI:-0.18--0.09).Furthermore,the unique effect of the PN scores on the CLS scores (sr2 =0.10) was higher than that of PCS scores (sr2 =0.06).Conclusion:The current research indicates that the loneliness,parental cohesion,peer acceptance and self-esteem of the left behind children have a close relationship.Furthermore,it suggests that self-esteem may play partial mediating effects between parental cohesion,peer acceptance and the loneliness of left-behind children.

ObjectiveTo observe the effects of comprehensive therapy on central pain after incomplete spinal cord injury. Methods12 patients with central pain after incomplete spinal cord injury who accepted comprehensive therapy were assessed with McGill pain questionnaire (MPQ) and visual analogue scale (VAS) before and after treating. ResultsThe scores of pain rating index sensory quality (PRI-S), pain rating index totality (PRI-T), the number of words chosen (NWC), pain rating index affective quality (PRI-A) and present pain intensity (PPI)max in MPQ and VAS were significantly decreased(P<0.01 or P<0.05).ConclusionThe comprehensive therapy is practical effective on central pain after incomplete spinal cord injury.

ObjectiveTo investigate current iodine nutritional status of different groups of people in Harbin city, and to provide the basis for development of salt iodization standard and scientific iodine supplementation.MethodsThree urban districts and three surrounding counties were chosen in Harbin,2011.In each chosen urban district and county,one district office (township) was selected,and one residents committee (village) was chosen in each of the district office(township),and 30 households were selected by systematic sampling.Iodized salt,water iodine and iodine intake per capita were investigated.In each of the residents committee (village),20 adults aged 18 - 45,30 pregnant women or lactating women,and 100 school children aged 8 - 10 were selected.Urine samples were collected and urinary iodine level were tested.Salt iodine was determined by direct titration,water and urinary iodine by arsenic cerium catalytic spectrophotometry.Iodine uptake and iodine nutritional status of different populations in Harbin urban and rural areas were compared.ResultsThe edible rate of qunlified iodized salt were 93.3％(84/90) and 96.3％(156/162) in Harbin urban and rural residents,respectively,which were all greater than 90％,and the highest value of salt iodine were 38.3,46.0 mg/kg,respectively,in urban and rural areas,which all did not exceed the upper limit(50 mg/kg) of qualified iodized salt,but there were some samples of salt iodine content below the national standard(20 mg/kg).Water iodine value in urban and rural areas,even the highest value(9.40,8.40 μg/L),was failed to meet the national standard 10 μg/L; salt eaten by rural people perperson a day(8.33 g) was significantly higher than that of the urban people(7.03 g,Z=- 2.750,P ＜ 0.01); in addition to rural children aged 8 - 10,whose urinary iodine value(228.6 μg/L) was higher,the values in urban and rural adults ( 111.3,195.6 μg/L),pregnant women ( 193.0,172.9 μg/L),lactating women ( 128.4,173.7 μg/L)and urban children ( 186.8 μg/L ) were all in appropriate level.The urinary iodine medians ( 195.6,228.6 μg/L )of adults and children in rural were significantly higher than that of urban adults and children(111.3,186.8 μg/L,Z =- 2.294,- 5.434,P ＜ 0.05 or ＜ 0.01,respectively).Population composition of iodine deficiency in both urban and rural adults,lactating and pregnant women[46.7％(28/60),21.6％(13/60) ; 21.1％(19/90),21.3％ (18/89) ; 27.8％ ( 25/90 ),42.2％ (38/90) ] were significantly higher than that of the population composition with iodine excess[4.6％(4/60),5.0％(3/60) ; 16.7％(15/90),16.9％(15/89) ; 4.4％(4/90),0.0％(0/90)],but proportion of iodine excessive population in rural children [26.3％(79/300)] was significantly higher than proportion of iodine deficiency[5.6％(17/300)].ConclusionsThe natural environment of Harbin city is still in the iodinedeficient state.In addition to children in rural areas,the iodine intake and iodine nutrition level is basically appropriate; the risk of disease caused by iodine deficiency in adults,lactating and pregnant women is higher than by iodine excess,but the situation of children in rural is on the opposite.Therefore,we should strengthen the monitoring of different populations,and supplement iodine scientifically based on their need.

Objective To investigate the effect of the calmodulin kinase Ⅱ Inhibitor KN-93 on L-typecalcium current(ICa,L)and intracellular calcium concentration([Ca2+]i)in hypertrophic cardiac myocytes.Methods Forty-eight female New Zealand white rabbits were randomized(random number)into four groups(12 animals in each group):the sham operation group(sham group),the left ventricular hypertrophy group(LVH group),the myocardial hypertrophy + KN-93 group(KN-93 group),and the myocardial hypertrophy + KN-92 group(KN-92 group).Myocardial hypertrophy in the rabbits was established by coarctation of the abdominal aorta.In the sham group,the abdominal aorta was dissociated without coarctation.Eight weeks after coarctation,single ventricular myocytes were isolated by enzymaticdissociation,and ICa,L was recorded using perforated-patch recording(PPR)techniques.[Ca2+]i was measured using single-cell calcium imaging with the fluorescence calcium indicator dye fura-2/AM.Results Cardiac hypertrophy was successfully established after 8 weeks of coarctation of the abdominal aorta.The peak ICa,L in the LVH group and the sham group was(1.38 ± 0.3)nA and(0.87 ± 0.1)nA at 0 mV,respectively(P ＜0.01,n =12).There was no significant difference in Ica,L density between the LVH group and the sham group[(6.7 ±1.0)pA/pF vs.(6.3±0.7)pA/pF; P≥0.05,n=12].The addition of either KN-92(0.5 μmol/L)or KN-93(0.5 μmol/L)to the perfusing solution caused a modest steady-state inhibition of peak ICaL(9.4％ ±2.8％,KN-92; 10.5％ ±3％,KN-93)(P≥0.05,n =12)at 0 mV.However,at a higher concentration(1 μmol/L),KN-93 more potently inhibited peak ICa,L(40％±4.9％)compared to KN-92(13.4％ ± 3.7％ ; P ＜ 0.01,n =12).Resting[Ca2+]i levels in fura-2-loaded myocytes isolated from the sham,LVH,KN-92,and KN-93 groups were(98 ± 12.3)nmol/L,(154 ± 26.2)nmol/L,(147 ± 29.6)nmol/L,and(108 ± 21.2)nmol/L,respectively.Conclusions The CaMK Ⅱ specific inhibitor,KN-93,can effectively block ICa,L and reduce intracellular calcium overload in hypertrophic cardiac myocytes.This action may account for the antiarrhythmic effect of KN-93 in hypertrophic ventricular myocardium.

Objective To estimate prenatal diagnoses strategy with abnormal results of non-invasive prenatal testing (NIPT) based on a case of mosaic for trisomy 22.Methods The pregnanct woman was recruited from Department of Prenatal Diagnosis Center of Xinhua Hospital.Ultrasound scans suggested fetal nuchal translucency was 3.5 mm.Peripheral venous blood was drawn from the pregnant woman for NIPT at 12+2 weeks gestation.For further prenatal diagnosis, amniocentesis was conducted at 16+2 weeks gestation, and karyotype analysis combination with chromosome microarray analysis (CMA) was executed to analysis amniocytes.Results NIPT results suggested that chromosome 21, 18 and 13 were normal and supplementary reports suggested that chromosome 22 were slightly above the normal range.Karyotype analyzed 35 cultured cells.Each of them revealed a normal female karyotype.However, CMA results suggested that chromosome 22 gain mosaic and its copy number was 2.26.The fetus was diagnosed as high possibility of mosaic for trisomy 22.Conclusions Combined with the NIPT results, which was slightly gain mosaic of chromosome 22, a prenatal diagnosis strategy were proposed.When NIPT results suggest chromosomal abnormities, karyotype analysis combination with CMA to diagnose were recommended.

AIM:To investigate the surgical method and extent of reoperation in the concomitant strabismus patients with surgical under-correction and over-correction.
METHODS: Ninety - six concomitant strabismus patients with surgical under - correction and over -correction were recruited in this study, which included 41 males and 55 females, aged 21. 90±14. 70. All individuals underwent routine eye examinations for strabismus before the surgery. Among the cases with concomitant esotropia, there were over-correction in 23 cases, under-correction in 15 cases. Among the cases with concomitant exotropia, there were over-correction in 28 cases, under - correction in 30 cases. The method of reoperation were based on angle of deviation, the method of original operation and acute visual acuity of patients.
RESULTS:In over - correction cases with concomitant esotropia, medial rectus muscle of 9 cases were advanced, the corrective extent was (5. 51±2. 63) ? / mm;9 cases were performed advance of medial rectus muscle and recession of lateral rectus muscle, the corrective extent was (6. 25±1. 59) ? / mm; 3 cases were performed resection of medial rectus muscle and recession of lateral rectus muscle, the corrective extent was (4. 26±1. 04) ? /mm; only 2 cases were performed recession of lateral rectus muscle, the corrective extent was (4. 21±1. 91) ? /mm. In under - correction cases with concomitant esotropia, 6 cases were performed resection of lateral rectus muscle, the corrective extent was (4. 03±0. 98) ? /mm; 6 cases were performed resection of lateral rectus muscle and recession of medial rectus muscle, the corrective extent was (6. 86 ± 1. 32) ? / mm; 3 cases were performed recession of medial rectus muscle, the corrective extent was ( 4. 33 ± 0. 29 ) ? / mm. In over -correction cases with concomitant exotropia, 16 cases were performed advance of lateral rectus muscle, the corrective extent was (5. 37 ± 1. 56) ? / mm; 6 cases were performed recession of medial rectus muscle, the corrective extent was (6. 29 ± 3. 68) ? / mm; 5 cases were performed advance of lateral rectus muscle and recession of medial rectus muscle, the corrective extent was (5. 46±1. 78) ? / mm; 1 case were performed resection of lateral rectus muscle, the corrective extent was 5. 00? / mm. In under - correction cases with concomitant exotropia, 12 cases were performed resection of medial rectus muscle, the corrective extent was (4. 47 ± 0. 54) ? / mm; 16 cases were performed recession of lateral rectus muscle and resection of medial rectus muscle, the corrective extent was ( 5. 11 ± 0. 75 ) ? / mm; 2 cases were performed recession of lateral rectus muscle, the corrective extent was (2. 65±0. 42) ? / mm.
CONCLUSION: In reoperation of concomitant strabismus patients with over-correction, weakening or/and strengthening the horizontal muscle which were performed surgery before has a greater and more unstable surgical corrective extent. While In reoperation of concomitant strabismuspatients with under -correction, weakening or/ and strengthening the horizontal muscle which were not performed surgery has a normal corrective extent as usual.

AlM:To observe the changes of binocular vision in V-pattern exotropia children before and after surgical correction, and the effect of training in reconstructing the binocular vision after surgical corrections.METHODS: Sixty V-pattern exotropia children were enrolled in this study and were divided into three groups according to their age:group A (4~6 years old), group B (7~9 years old), and group C (10~12 years old), 20 cases for each group. Patients received routine refraction and ophthalmic examinations. Distance and near deviation were measured by prism-covering method and synoptophore. The simultaneous perception and fusion were examined with a synoptophore, and the stereacuity was measured with stereograms ( Titmus) . The children who didn’t reconstruct binocular vision function 1wk after surgery received binocular vision training. The data were recorded before and 1 , 2, 4, and 8wk after surgery. RESULTS: Binocular vision significantly improved among the children after surgery in group A and B ( P<0. 05 ) . Significantly divergence showed between group C and the other groups 1wk after surgery ( P < 0. 05 ). Binocular vision of the three groups all significantly improved 8wk after surgery, with no significant differences (P>0. 05). CONCLUSlON: V - pattern exotropia children can benefit from early surgical correction and training after surgery in reconstruct binocular vision.

Objective To evaluate the efficacy of nursing in percutaneous coronary intervention (PCI)for a patient with myocardial infarction and heart failure under the support of extracorporeal membrane oxygenation (ECMO). Methods An 85-year-old man suffered from myocardial infarction twice during 1-month hospitalization and complicated with a severe heart failure (eject fraction is 27%), pleural effusion and pulmonary infection. We decide to perform PCI under the support of ECMO for his hemodynamic instability. The key point of nursing in PCI under the support of ECMO: On the one hand, pre-PCI interview and preparation of all the drugs and items needed in operating ECMO 1 day in advance were key steps to guarantee the successful operation. On the other hand, high standard nursing technique, mastery of knowledge about ECMO and tacit cooperation with doctor were the bases of the successful operation. Results Under the support of ECMO, the patient' s hemodynamic condition came to stable. He underwent the coronary angiography and was implanted a stent in left coronary artery successfully under the meticulous care of doctor and nurse. Conclusions ECMO could provide life support for patients with severe heart failure. The adequate preparation for ECMO could guarantee the successful operation for nurse in catheter lab. Both intra-operative warming and prevention of postPCI fever caused by cold stimulation are important nursing measures.
