Breast cancer is the most common cancer among females. During the time of treatment and rehabilitation, the patients and their relatives need to help them to prevent, control or relieve all sorts of complications and adverse events that beyond their medical, surgi-cal or radiation interventions, called Supportive Care Need. There are many tools to evaluate these needs, such as Supportive Care Need Sur-vey, Cancer Patients Needs Questionnaire, etc., and mainly involved the needs of health system, information, patient support, psychology, physical and daily living, and sexuality, varied with the factors of social demography, disease and treatment, and psychology;and the inter-ventions contain cognitive behavior and psychology.

Objective To investigate the correlation between professional commitment and academic self-efficiency of nursing undergraduates.Method A total of 258 students were investigated by nursing professional commitment questionnaire and academic self-efficiency scale.Results The score of professional commitment was (89.05±14.92) and the academic self-efficiency was scored (73.78±10.38).The professional commitment was positively correlated with academic self-efficiency (P＜0.01).Conclusions There are close relationships between professional commitment and academic self-efficiency for nursing undergraduates.The nursing educator should take effective measures to improve nursing students' professional commitment and academic self-efficiency.

Objective To investigate the clinical features of polypoidal choroidal vasculopathy (PCV) in Chinese patients. Methods The clinical data of 71 continuous patients (142 eyes) who were diagnosed with PCV by fundus photography, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optical coherence tomography (OCT) were analyzed retrospectively. Results Eleven patients (11 eyes) of 71 patients (142 eyes) were diagnosed with PCV to make up 15.49% and 7 75% of the numbers of patients and affected eyes respectivery. The patients included 7 males (63 6%) and 4 females (36 4%). The predominant location for these lesions was the macular region in 10 eyes (90 9%). Fundus examination demonstrated the reddish-orange nodular elevations in 6 eyes. ICGA revealed umbrellalike or twiglike branching vascular networks and polypoidal dilations at the vascular terminals of the branches in all patients, and feeder vassels within choroidal vascular networks were found in 8 eyes. OCT images of retinochoroidal structures showed prominent anterior protrusion of the orange subretinal mass corresponding to the polypoidal structure in the indocyanine green angiogram. An apparent discontinuity was observed in the highly reflective layer which delineates the polypoidal structure. Conclusions PCV mainly affects the male over 50 years and the eyes involved were mostly unilateral. Most of polypoidal vascular lesions are present in the macular area.

Zebrafish was selected as model animal, and glucocorticoid dexamethasone was used as a model compound to establish a rapid and high efficient osteopenia model. Zebrafish larvae at 4 days post fertilization (dpf) were exposed to a serial concentrations of dexamethasone solutions, and 0.5% DMSO was selected as the vehicle control group. All groups were incubated in 24-well plates (28.5 degrees C) until 9 dpf. In addition, effects of 10 micromol x L(-1) dexamethasone on preventing against osteopenia induced by etidronate disodium were also investigated. Zebrafish bones at 9 dpf were stained with alizarin red. Quantitative analysis of the stained area was performed by microscopic inspection and digital imaging methods to reflect the amount of bone mineralization. Results showed that dexamethasone group at 2.5, 10 and 25 micromol x L(-1) can decrease the staining area and the staining optical density values of zebrafish head bones when compared with the vehicle control group (0.5% DMSO), which suggested that dexamethasone can significantly reduce the zebrafish mineralized bone and the bone mineral density. Results also showed that 15 and 30 microg x mL(-1) etidronate disodium can increase the mineralized matrix of zebrafish head bone and prevent against osteopenia induced by dexamethasone. In conclusion, the study indicated that zebrafish can be an idea osteopenia model induced by dexamethasone.

Objective To do a longitudinal study of nursing undergraduates′ humanistic care ability in different period of clinical practice, and analyze its trend, aiming to provide reference about how to intervene to enhance the nursing undergraduates' humanistic care ability. Methods A total of 67 nursing undergraduates were investigated about their humanistic care ability with the Care Ability Inventory (Caring Ability Inventory, CAI) at the beginning, middle and end of the internship. Results The scores of seniors′ humanistic care ability at the beginning, middle and end of the internship were 194.97±22.93, 192.18±26.87, 187.24±22.15, and there was a statistically significant difference among the three time points (F=3.234, P<0.05), there was significant difference of the dimension of courage in different periods (F=7.511, P<0.01). Conclusions There is a downtrend of nursing undergraduates′humanistic care ability in different stages of clinical practice, and we suggest that nursing educators and administrators should consider the characteristics of different periods in the clinical practice, and then do a targeted training to foster nursing students′humanistic care ability.

Objective:To summarize the clinical features, genetic testing and treatment efficacy of 6 children with Dent disease.Methods:Six children diagnosed with Dent disease in Guangzhou Women and Children′s Medical Center from January 2014 to March 2019 were enrolled.Their medical history, clinical manifestations, laboratory results, genetic test results, and proteinuria level, calciuria level and renal function after medication were measured.Results:All patients were male, with the onset age ranged from 1 to 9 years old.They were followed up for 6 months to 4 years.All the children had low molecular weight proteinuria.Urine protein electrophoresis showed that the ratio of low molecular weight proteinuria in only 2 cases was more than 50%.Renal biopsy suggested that all cases were combined with glomerular lesions.Five cases had hypercalciuria.Under the microscope, there were 5 cases of hematuria.Two case had rickets, and there was no renal calcium deposition and hypophosphatemia.Five cases were detected with CLCN5 mutations, of which p. C160Yfs*49 and p. G523D were first reported.One case had an OCRL1 mutation.Patients were treated with Hydrochlorothiazide and angiotensin converting enzyme inhibitor (ACEI). The 24 h urinary calcium level after treatment was lower than that before treatment [0.40 (0.24, 0.43) mmol/kg vs.0.12 (0.11, 0.14) mmol/kg, U=2.00, P<0.01]. However, there was no significant decrease in the 24 h-urinary protein level before and after treatment [77.09 (62.41, 88.01) mg/kg vs.80.33 (66.03, 92.52) mg/kg, U=12.00, P>0.05]. Conclusions:Dent disease is mainly characterized by low molecular weight proteinuria, and some patients may not be associated with hypercalciuria.Gene tests help to identify the disease type.ACEI and Hydrochlorothiazide can reduce the urinary calcium level, but cannot improve the level of urinary protein.

Objective:To prepare monoclonal antibody ( mAb ) against human testis-specific conserved gene ( hTSC29 ) peptides and characterize its immunological and biological features.Methods:According to bioinformatics analysis and prediction of the antigenicity, surface property, hydrophilicity and flexibility of hTSC29, a 18-amino acid residue partial peptide of hTSC29 was synthesized,then immunized the BALB/c mice for preparing antiserum.The mAb against hTSC29 was produced using the routine hybridoma technique.The properties of the mAb against hTSC29 were identified by ELISA, Western blot and immunohistochemistry staining.Results:After cell fusion and subcloning, one hybridoma cell lines secreting specific mAb against hTSC29 protein were obtaind.The Ig subclass of the mAb was IgG2b(κ).ELISA detection showed that the titer of mAbs in cultured was 1∶104.Western blot analysis proved that the mAb could specifically recognize Mr 60 000 protein in human testis total protein.The hTSC29 protein main located at circumference of spermatocyte and spermatid in human testis tissue by immunohistochemistry staining and immunofluorescence assay.Conclusion:One hybridoma cell lines which can secrete specific mAb against hTSC29 protein with high titers and specificity have been established successfully.The mAb will provide efficient tools for functional studies of hTSC29 expressed in spermatogenesis.

Objective To investigate the clinical efficacy of plate fixation with in situ reinforcing ulnar nerve and anterior transposition by olecranon osteotomy approach in the treatment of type C2 and C3 humeral intercondylar fractures.Methods A retrospective case control study was conducted to analyze the clinical data of 23 patients with humeral intercondylar fractures admitted to the Affiliated Hospital of Hangzhou Normal University from June 2014 to January 2017.There were 17 males and six females,aged 19-56 years,with an average of 41.2 years.According to AO classification,there were 15 patients with type C2 and eight with type C3.All patients were treated with plate internal fixation by olecranon osteotomy approach.The patients were divided into anterior group (11 patients) which was treated with ulnar nerve release anterior transposition and in situ reinforcing group (12 patients) which was treated with ulnar nerve release in situ.The operation time,intraoperative blood loss,fracture healing time,elbow flexion and extension range,elbow joint Mayo score,and excellent and good rate were compared between the two groups.Postoperative complications were recorded.Results All patients were followed up for 15-43 months,with an average of 26.7 months.All patients had no need of blood transfusion.There were no significant differences between anterior group and in situ reinforcing group in operation time [(219.1 15.1) minutes vs.(211.2 ± 17.1) minutes],intraoperative blood loss [(263.6 ± 35.3) ml vs.(237.5 ±25.6)ml] and fracture healing time [(18.2±2.4)weeksvs.(18.9±1.7)weeks] (P＞0.05).Nosignificant differences were found between the two groups in elbow flexion [(120.3 ±7.1) ° vs.(120.3 ±4.1)°],straightness [(3.7±2.7)° vs.(4.1 2.4)°],Mayo score [(89.09 ±9.17)points vs.(86.67 ±10.29)points] and excellent and good rate [91％ (10/12) vs.83％ (10/12)] (P ＞0.05).After operation,no complications such as infection,heterotopic ossification,ulnar neuritis,elbow valgus deformity,or internal fixation failure occurred.Conclusions For humeral intercondylar fracture,the plate fixation with in situ reinforcing ulnar nerve and anterior transposition by olecranon osteotomy approach both have advantages such as small surgical trauma,strong fixation,fewer complications,satisfactory recovery of elbow function.Ulnar nerve anterior transposition or not does not affect the occurrence of ulnar neuritis,and both can obtain satisfactory clinical efficacy.

Objective To observe the level of supportive care need and quality of life in patients postoperation for breast cancer and ac-cepting chemotherapy, and the relationship between them. Methods From September, 2015 to June, 2016, 235 patients with breast cancer af-ter surgery were conveniently sampled, and investigated with the general situation questionnaire, Supportive Care Need Survey Short-form (SCNS-SF34) and Functional Assessment of Cancer Therapy-Breast (FACT-B). Results A total of 230 patients were analyzed. Patients self-reported to need supportive care in all dimensions of SCNS-SF34, and the most frequency was in the health information (31.30％). The score of FACT-B was (93.25±23.53), that needed further improvement. The needs of supportive care in each dimension negatively correlat-ed with the scores of FACT-B in the dimensions (|r|>0.168, P<0.05) except society/family and function. Conclusion The patients with breast cancer need variety of supportive care, which may impact their quality of life.
