Objective To evaluate the application effect of continuity care model for hospitalized infertile patients after discharging from hospital. Methods Select 108 cases of infertility patients were randomly divided into trial group and control group, each group of 54 cases, control group given routine nursing intervention, intervention group in conventional nursing care and treatment on the basis of implementing continuity nursing intervention, intervention 6 months after the evaluation of two groups of patients with anxiety, depression, quality of life, and pregnancies. Results The scores of SAS and SDS were (48.32 ± 11.28), (50.62 ± 11.20) points before in the intervention group, and after the intervention (34.63 ± 8.95), (37.68 ± 9.72) points, and there were significant difference(t=-5.478, P<0.05;t=-4.840, P<0.05);before in the intervention , the scores of SAS and SDS were (49.76±13.08), (48.64±12.23) points in the control group, and after the intervention (41.18 ± 12.84), (40.31 ± 10.12) points, and there were significant difference (t=-7.361, P<0.05;t=-4.840, P<0.05), and there were significant differences in two group after intervention (t=6.682, P<0.05;t=7.341, P<0.05). The scores of quality of life were significant differences after intervention in two group, and six months after the intervention, the experimental group intrauterine pregnancy rate is higher than the control group (χ2=46.790, P < 0.05). Conclusions Applying continuity care model e for hospitalized infertile patients can improve the psychological state, reduce depression and anxiety, increase the quality of life and rate of pregnancy.

Objective To investigate the perioperative health care to patients with perineal endometriosis (PME) involving anal sphincter.Method The clinical data of 17 patients diagnosed with PEM involving anal sphincter at the Peking Union Medical College Hospital from January 2009 to June 2013 were analyzed retrospectively.Results The perineal incisions in all cases were satisfactorily healed,without any fatal incontinence or other complications.There was only one case of recurrence,accounting for 5.9%.Conclusion Preoperative psychological nursing,postoperative close observation on the incisions,diet instructions,management of defecation and targeted health education can all contribute to patients’ recovery.

Radiotherapy plays a crucial role in cervical cancer.Intensity modulated radiation therapy is widely used gradually,which allows the photon beam within each field to be modulated and therefore improves the dose distribution by maximizing target coverage and minimizing the damage to normal tissue.Concurrent radiochemotherapy plus brachytherapy are standard therapeutic methods for local advanced cervical cancer.

OBJECTIVETo correct the minor breast ptosis with minimal breast scar.

METHODS32 cases with minor breast ptosis were corrected by subfascia breast augmentation with periareolar incision and anatomic mammary implant.

RESULTBreast ptosis was completely or mostly corrected in all the patitents with periareola scar, avoiding the vertical breast scar. Except for short-time effusion in 2 cases, no other complication happened.

CONCLUSIONSSubfascia breast augmentation with periareolar incision and anatomic mammary implant can effectively correct minor breast ptosis with minimal breast scar and less complication.

Objective To introduce the technical key points and clinical efficacy of dual plane breast augmentation under endoscope through a transaxillary incision.Methods By analyzing the 89 surgical cases,we have summarized the key points of the pre-operative design,surgical skills and postoperative management.Results All patients had no uncontrolled bleeding during operation and loss of nipple and areola sensation.71 patients got 6-12 months follow-up,showing that only one case presented with unilateral capsular contraction,and the others had satisfied results.Conclusions Blunt dissection can reduce the risks of uncontrolled bleeding on the inner side of the pocket and the damage of the nerves on the lateral side of the dissecting pocket.The lower inner part,lower part and lower lateral part are the areas that could be sharply dissected by electrocautery under endoscope to achieve the dual plane Ⅰ.The drainage and bandage are necessary after the operation.

Objective To investigate the effect of exogenous orexinA on the pyramid neurons and interneurons in the prefrontal cortex prelimbic(PL)area.Methods The pyramid neurons and interneurons in PL area of Kunming mice were selected from prefrontal cortex slices by infrared visual patch clamp technique.The morphology and electrophysiological features of the pyramid neurons and interneurons were observed.The effect of exogenous orexinA at a concentration of 400 nmol/L on these cells was studied using the whole cell configuration.Results The pyramid neurons were large,pyramidal in cell body with clear apical dendrites extending vertically and several basal dendrites radiating.The interneurons were comparatively smaller and had several processes from cell body.In current clamp mode,all 54 pyramid neurons having been recorded showed frequency adaption,and the 15 recorded interneurons discharged rapidly and had no frequency adaption.While in vol-tage clamp mode,36 pyramid neurons were regarded as Ih(+)pyramid neurons for recorded hyperpolariztion-activated cation current,and the left 18 and 15 interneurons were Ih(-).Exogenous orexinA had a total reaction rate of 51.9% on 54 recorded pyramid neurons under current clamp,and a rate of 66.7% on 36 Ih(+)pyramid neurons and of 22.2% on the Ih(-)pyramid neurons under voltage clamp.All 15 recorded interneurons had no reaction to exogenous orexinA under either mode.Conclusion OrexinA plays excitatory effect on pyramid neurons in the prefrontal cortex PL area,and this effect is much more noticeable in pyramid neurons with Ih currents.

BACKGROUND: Generally speaking, neuroendocrine cells have been not observed in normal breast tissue but found in breast carcinoma tissue which was affected by local microenvironment and hormone level during differentiation of breast epithelial stem cells.OBJECTIVE: By detecting expressions of breast cancer resistance protein (BCRP), cytokeratin-8 (CK8), and chromogranin-A (CgA) in breast carcinoma tissue, to explore the possible mechanism of neuroendocrine cells observed in breast carcinoma tissue during differentiation of multi-lineage potential of bone marrow mesenchymal stem cells.METHODS: BCRP, CK8, and CgA were used as markers for SP stem cells, glandular epithelium differentiation, and neuroendocrine differentiation, respectively. Immunohistochemistry was used to detect the expressions of BCRP, CK8, and CgA in breast tissues of 89 subjects and analyze their correlation. RESULTS AND CONCLUSION: Both BCRP and CK8 expressions were observed in normal breast tissues, hyperplastic tissues, and breast carcinoma tissue. BCRP expression was increased in the breast carcinoma tissue; CK8 expression was decreased with the abnormal differentiation of breast tissue; CgA expression was only detected in breast carcinoma tissue. BCRP expression was significantly correlated with positive CgA expression (P < 0.01), but it was no correlation with positive CK8 expression in normal breast tissues, hyperplastic tissues, and breast carcinoma tissue (P=0.069). The results suggested that neuroendocrine cells were not observed in both normal breast tissues and hyperplastic tissues but in breast carcinoma tissue, which possibly correlated to differentiation of multi-lineage potential of bone marrow mesenchymal stem cells.

Background Econazole nitrate is not effective as an antifungal eyedrop because of its poor intraocular permeability,therefore changing the formulation of econazole nitrate to improve its intraocular permeability become a critical point in the treatment of intraocular fungal infection. Objective The present study was to observe the penetration of 0.5％ econazole nitrate nanoparticles in the corneas and aqueous humors following its topicaladministration. Methods Econazole nitrate nanoparticles were prepared by quasi-emulsion solvent diffusion.Characteristics and size of nanoparticles were examined with transmission electron microscope and laser scatteringmethod,respectively.Econazole nitrate nanoparticles drops (0.5％ )was topically administered in 27 New Zealandwhite rabbits bilaterally,and aqueous humor and corneas were obtained after the application of the eye drops for 5,15,30,45,60,90,120,180,240 minutes respectively to detect the concentration of econazole nitrate with highperformance liquid chromatography (HPLC). The pharmacokinetic parameters were calculated with 3 p97pharmacokinetic computer software.The use of the animals followed the Regulation for the Administration of AffairsConcerning Experimental Animals by State Science and Technology Commission. Results The diameter of thenanoparticles was 50 nm with the round shape and encapsulation efficiency was 96.0％.Econazole nitrate nanoparticlesat the concentration of 0.5％ could be rapidly separated with other elements by HPLC with a lowest quantitativeconcentration of 0.1 mg/L.The mean recovery rates of econazole nitrate nanoparticles were 98.09％ in cornea and 99.66％ in aqueous humor,respectively after topical administration.The peak levels of econazole nitrate nanoparticles in cornea and aqueous humor were achieved at 5 minutes after application ( cornea:40.620 μg/g± 7.756 μg/g;aqueous humor:0.504 mg/L±0.153 mg/L),and its half-life( t1/2 )in cornea and aqueous humor was 23.5 minutes and 18.6 minutes,respectively. Conclusions Econazole nitrate nanoparticles at 0.5％ concentration can remain a feasible bioavailability in ocular tissue and therapeutic level in cornea and aqueous humor.

Objective To investigate and evaluate the polymorphism distribution of arsenic(+3 oxidation state)methyhransferase(AS3MT)5'-UTR VNTR in Chinese populations.Methods Genomic DNA was extracted from peripheral blood anti-coagulated with ACD of 1440 individuals in a standard phenol-chloroform protocol.The phenotypes of AS3MT 5'-UTR VNTR were determined by polymerase chain reaction(PCR)associated with agarose gel electrophoresis.Results Of the 1440 individuals,771(53.5%),426(29.6%),211(14.7%),16(1.1%)and 16(1.1%)were carriers of the V2/V3(AB/A2B),V3/V3(A2B/A2B),V2/V2(AB/AB),V2/V4(AB/A3B)and V3/V4(A2B/A3B)genotype,respectively.The AB(V2),A2B(V3)and A3B(V4)allele frequency was 41.9%,57.0%,1.1%respectively.The differences of AB(V2)and A2B(V3)allele frequency were all significant between the northern and southern populations respectively(χ2=23.39,χ2=33.28,P＜0.007).Conclusions In different regions the AB(V2)and A2B(V3)allele frequency is different,the AS3MT 5'-UTR VNTR polymorphism can be used to evaluate the susceptivity of arsenieosis.
