Objective To find ways to reduce vascular crisis of the patients undergoing replantation of severed fingers by pain, adverse analgesics and sleep quality with auricular seeds pressing. Methods 310 digital replantation patients were divided into 2 groups according to admission time. There were 155 cases in the traditional group treated with routine postoperative care ,while 155 cases in the controlled group treated with routine postoperative care plus auricular seeds pressing. Results The scores of pain, adverse analgesics and sleep quality in two groups were statistically significant ( P<0.05). The rate of vascular crisis of the traditional group [18.06%(28/155)] was much more higher than the controlled group [5.16%(8/155)], the difference was significant, χ2=12.571, P < 0.01. Conclusion In digital replantation, auricular seeds pressing was effective to pain relieving, constipation and reduce adverse reactions, and could significantly improve sleeping time and survival rate of the severed fingers.

Objective To study the effect of nasal tolerance with a dual analogue (Lys262 Ala207) on experimental autoimmune myasthenia gravis (EAMG) and the underlying mechanisms, the clinical and immunological changes were observed in Lewis rats treated with dual analogue Methods Different doses of dual analogues were given to Lewis rats immunized with acetylcholine receptor (AChR) in complete Freud's adjuvant (CFA) and the medium dosage was chosen in the following studies As comparing the effects of treatment of the predetermined dosage of dual analogue at different time points, the body weight and clinical symptoms of Lewis rats immunized with AChR in CFA were evaluated The levels of anti AChR IgG in serum were tested by ELISA Proliferative responses of lymphocytes to no antigen, AChR, dual analogue, control MBP peptide, MBP, or Con A were tested Results Lewis rats receiving dual analogue nasally for 10 consecutive days at the time of immunization (Group A) or the first day after complete remission from the acute phase of the disease (Group B) sparsely developed EAMG with reduced severity than the corresponding control groups The subsiding disease was associated with decreased amount of anti AChR IgG in serum expressed as optic density ( A ) at 405 nm On day 35 post immunization, the A values in group B vs control group were 0 95?0 26 and 1 19?0 12, respectively Proliferative responses expressed as stimulation index (SI) were suppressed in response to antigen specific stimulations in rats receiving dual analogue as compared with rats receiving control peptide For instance, the values of SI in response to AChR in group A and control group were 1 71?0 78 and 3 24?1 31, respectively Those values were suppressed to a less extent in group B vs control group (1 97?0 56 vs 3 19? 1 50) Conclusions Nasal administration of a dual analogue Lys262 Ala207, at two different time points post immunization should ameliorate muscular weakness in EAMG rats involved in decreased levels of anti AChR antibodies and antigen specific T cell proliferation

Objective To explore the clinical nursing methods for the treatment of the skin degloving injury in foot by the combination of free femoral anterolateral skin flap transplantation and vacuum sealing drainage (VSD) technique. Methods From January 2010 to January 2014, 18 cases of the skin degloving injury in foot were treated by debridement and implant skin, negative pressure drainage and irrigation at first period, then the operation to repair the foot wound by transplant femoral anterolateral skin flap were done at second period. Nurses applied the key technology of VSD into postoperative nursing. Nurses should master the observation method and characteristics for the flow of blood to the flap skin, the method for foot position nursing, afford effective analgesic care, and flap local high flow oxygen therapy,improve the local tissue oxygen partial pressure and introduce the foot early functional exercise during postoperative. Results Eighteen cases flaps all survived. Clients were followed-up for 6 to 12 months,the discovery showed that all of the clients had good flap blood supply,the skin was soft and elastic,and the function of foot were recovered well. Conclusions The combination of of free femoral anterolateral skin flap transplantation and VSD technique apply into foot degloving injury repairation postoperative care,by application of high quality nursing, it really can improve the success rate of surgery and reduce the pain for clients.

Objective To observe the effect of mirror therapy and sensory reeducation on sensory function recovery after thumb recon-struction with second toe transplantation. Methods Forty patients after thumb reconstruction with second toe transplantation from January, 2011 to January, 2014 were divided into control group (n=20) and training group (n=20). Both groups accepted routine nursing and rehabili-tation, while the training group accepted mirror therapy and sensory reeducation training in addition. They were followed up for six to eigh-teen months after operation (average 9.3 months) with the two-point discrimination (2-PD) of transplanted toe pulp. Results 2-PD was (7.15±1.15) mm in the training group, very shorter than (10.23±2.23) mm of the control group (t=5.4898, P<0.001). Conclusion The mirror therapy combined with sensory reeducation training can improve the sensory function of the finger pulp that transplanted from the second toe.

Objective To investigate the expectation values of dental esthetics during the orthodontic treatment in adolescents with malocclusion.Methods 14～18 year-old adolescents with malocclusion were randomly divided into the treatment group (30 cases) and the control group (21 group) for a prospective study with a period of 1.5 years (0,0.5,1.0,1.5 year respectively),esthetics components of index of orthodontic treatment need (IOTN-AC) and self-made sheet for expectation values of dental esthetics were used to evaluate the values during the follow-up.Results During the follow-up,the IOTN-AC values in the treatment group were decreasing,conversely,the values in the control group were increasing,the expectation values of dental esthetics were increasing in both of the two groups,the differences above were significantly.Conclusions Expectation values of dental esthetics were higher during the follow-up in both of the treatment and untreatment cases,so the dentists and the nurses should encourage the consolidation therapy in treatment cases,and persuade the untreatment cases for orthodontic therapy in order to improve their psychological needs.

Objective To study the prophylactic effects of nasal tolerance with a dual analogue (Lys262-Ala207) on experimental autoimmune myasthenia gravis (EAMG) and observe the underlying mechanisms, the clinical and immunological changes in Lewis rats treated with dual analogue nasally. Methods The effects of the predetermined dosage of a dual analogue Lys262-Ala207 were compared at different time points, and the dual analogues or control peptides were given nasally before (Group A or CA) or on the day (Group B or CB) of immunization with acetylcholine receptor (AChR) in complete Freund's adjuvant for 10 consecutive days. The clinical scores were evaluated for 50 days after immunization. The levels of anti-AChR IgG in serum were tested by RIA. Proliferative responses of lymphocytes to no antigen, Lys262-Ala207, AChR, AChR-?100-116, MBP peptide, or Con A were tested. The numbers of mononuclear cells expressing CD4 and/or CD25 from lymph nodes were enumerated using flow cytometry. Results As compared with the corresponding control groups, Lewis rats in group A or B developed EAMG with reduced severity and loss of AChR within the neuromuscular junction. The levels of anti-AChR IgG (21.96?3.37 and 29.41?4.59) were also decreased. Proliferative responses were suppressed in response to antigen-specific stimulations in rats receiving dual analogue, whereas the numbers of CD4+CD25+ T cells were higher in group A (11.34%?1.62%) and B (8.68%?1.83%) than in their corresponding control groups. Conclusions Nasal administration with a dual analogue Lys262-Ala207, at two different time points before and on the day of immunization ameliorated muscular weakness in EAMG rats associated with decreased levels of anti-AChR IgG in serum, suppressed antigen-specific T cell proliferation and increased numbers of CD4+CD25+ T cells from lymph nodes as compared to rats receiving control peptides. The results of our study suggest that the mucosal tolerance with dual analogue should be served as an alternative maneuver in human MG.
