Objective To summarize the experience in perioperatively nursing 8 patients with pelvic cavity and genital tract aggressive angiomyxoma (AAM). Method The perioperative nursing care was given to 8 AAM patients who were hospitalized in the department of obstetrics and gynecology from January 2010 to June 2015. Results The abdominal and perineal wounds were healed well without complications. All patients were recovered and discharged. One case had a relapse 2 years and another did 3 years after operation. Conclusion Such nursing measures as preoperative psychological nursing, close observation of the disease conditions, nursing cooperation during rescue for postoperative bleeding, treatment of postoperative complications and enhancing health education concerning the importance of long-term follow-up can be helpful for their recovery.

Objective To study the effects of three therapies on shoulder pains after gynecological laparoscopies.Methods After the gynecological laparoscopies,180 patients were randomly assigned to hot compress group(n=57),oxygen therapy group (n=65)and routine care group as control group(n=58).All the patients in the three groups were given oxygen inhalation for three hours.Besides,those controls were given mental care,comfort support and massage,while those in the two experiment groups were managed with hot compress on the shoulder and oxygen inhalation via nasal tube at 2 L/min each for 2 hours at 8 am and 4 pm on the first day.The three groups were compared in terms of shoulder pains,at different time points on the first day(at 8 am,4 pm and 8 pm). Results After intervention,there were significant differences between the three groups in terms of shoulder pains(P<0?05).In both experiment groups,the scores on the shoulder pains after intervention were significantly lower than those before intervention(P<0?001). Conclusions Hot compress and oxygen treatment are both effective in relief of the shoulder pain after gynecological laparoscopy. Therefore,the therapy can be decided on economic conditions and postoperative rehabilitations.

With the development of dental implant techniques, dental rehabilitation of partially or totally edentulous patients with oral implants has become a common practice. Adequate bone volume in the implant area is a key factor for the success of implant restoration. However, insufficient bone volume in the implant area is very common in clinical practice, which jeopardizes the structural, functional, and esthetic outcomes of implant treatment. Bone augmentation with bone grafts is one of the methods commonly used in clinical practice to meet the requirements of implantation. Properties of bone grafts, such as biocompatibility,osteoconduction, osteoinduction and osteogenesis, are important to the success of bone augmentation. This paper reviews current research on dental bone grafts about their clinically relevant capabilities, classification and their potential development in the future, in order to provide theoretical reference for clinical application of bone grafts and successful implant restoration.

Objective To investigate the efficacy of acupuncture combined with doctor-nurse cooperation mode on stroke-associated pneumonia in patients with acute stroke. Methods 67 patients of acute stroke within 1 week in our hospital from March, 2013 to January, 2015 were randomly divided into control group (n=35) and treatment group (n=32). Both groups received neurological routine treatment and systematic rehabilitation training by professional physiotherapists under general nursing mode. The treatment group received acupuncture treatment under doctor-nurse cooperation mode additionally. Incidence of stroke-associated pneumonia, swallow function and aspiration rate were recorded. Results Compared with the control group, the incidence of stroke-associated pneumonia significantly decreased in the treat-ment group after treatment (χ2=4.615, P=0.032). The retention volume of epiglottic vallecula and pyriform sinus (tdilute barium=21.01, tthick barium=19.85), the duration of pharynx period (tdilute barium=17.03, tthick barium=13.68), and the start time of pharynx period (tdilute barium=19.63, tthick barium=17.86) were less in the treatment group than in the control group (P<0.05). In the test of dilute barium, the aspiration rate was lower in the treatment group than in the control group (χ2=4.03, P=0.044), however, there was no significant difference between 2 groups in the test of thick bari-um and solid food (P>0.05). Conclusion Acupuncture combined doctor-nurse cooperation mode may decrease the rates of aspiration and stroke-associated pneumonia in acute stroke patients through improving their swallow function.

Background The light damage model of retinal pigment epithelium (RPE) cells is a research direction of retinal degeneration diseases,and RPE cell apoptosis induced by light damage and inflammation is an important pathologic basis of light-induced RPE cell damage.However,whether endoplasmic reticulum stress (ERS) paticipates in light-induced RPE cell damage is rarely reported.Objective This study was to explore the effects of ERS on light-induced RPE cell damage.Methods Human RPE cell line (ARPE-19) was cuhured,and light damage models were created by irradiating the cells for 3-,6-,12-and 24-hours with white fluorescent lamp with the intensity of (2 000±500)lx for the selection of optimal irradiating time,and the cells in the normal control group were cultured in the dark environment.The cells were divided into normal control group,light exposure group and 4-phenylb utyric acid (4-PBA) pretreated +light exposure group.The cells from 4-PBA pretreated +light exposure group were cultued firstly with 4-PBA for 30 minutes and followed by light exposure for 12 hours.The apoptisis rate of the cells and intracellular reactive oxygen species (ROS) content were detected by flow cytometry;the concentrations of interleukin 1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the cell supernatant were assyed by ELISA.The relative expressing levels of activating transcription factor 6 (ATF-6),C/enhancer binding protein homologous protein (CHOP) and caspase-12 mRNA and protein in the cells were detected by real-time quantitative PCR and Western blot,respectively.Results The cultured cells showed a long spindle shape,the border was not clear,the cytoplasm was degranulation,and the cell fragments increased.Flow cytometry showed that compared with the normal control group,the ROS content in the cells and the apoptosis rate were evidently increased with the lapse of light exposure time (F=763.00,119.30,both at P＜0.01).ELISA results showed that the concentrations of IL-1β and TNF-α in the cell supernatant were significantly higher in the light exposure 6-hour group than those in the normal control group with the peak value in the light exposure 12-hour group.Compared with the normal control group,the relative expression levels of ATF-6,CHOP and caspase-12 mRNA and protein in the cells were elevated in the light exposure group and peaked in the light exposure 12-hour group.In addition,the relative expression levels of ATF-6 mRNA,CHOP mRNA and caspase-12 mRNA in the cells were significantly reduced in 4-PBA pretreated+light exposure group compared with the light exposure group (F=281.69,473.88,308.45,all at P＜0.01),and their proteins were also significantly reduced (F =47.86,57.93,106.59,all at P ＜ 0.01).The apoptosis rate,concentrations of IL-1β and TNF-α in the cell supernatant were significantly reduced in 4-PBA pretreated+light exposure group compared with the light exposure group (F =88.64,245.47,101.01,all at P＜0.01).Conclusions The light exposure at (2 000 ± 500)lx induces intracellular ROS accumulation and activates the ERS response,which results in apoptosis and inflammatory process of human RPE cells.4-PBA,a inhibitor of ERS,can suppress light-induced ERS response and therefore reduces the apoptosis rate and inhibits inflammatory process.

BACKGROUND:Severely curved root canal preparation is the difficulty during clinical root canal preparation, and improper preparation may induce complications such as stage, root canal offset and apical open, which affect the quality of root canal preparation and apical closure. Therefore, it is important to choose a root canal preparation instrument which has the best cutting and forming ability. OBJECTIVE: To compare the shaping ability of Mtwo nickel-titanium rotary instruments, K3 nickel-titanium rotary instruments and stainless steel K-files for the preparation of curved root canals. METHODS:A total of 30 severely curved root canals of freshly extracted human maxilary molars were randomly divided into three groups, with 10 canals in each group. The canals were prepared by Mtwo instruments, K3 instruments and K-files, respectively. The instrument’s tip location in pre- and post-instrumentation radiographs of the three groups was recorded; the changes of root curvature, working length and working time in the three groups were measured and compared. RESULTS AND CONCLUSION:The root curvature showed no significant difference in the three groups before preparation (P> 0.05). The changes of root curvature after root preparation in Mtwo instrument and K3 instrument groups were significantly less than that in K-files group (P < 0.01), and no significant difference was found between Mtwo instrument group and K3 instrument group (P > 0.05). The root canal preparation time in the three groups showed significant differences (P < 0.01), which was the shortest in Mtwo instrument group and the longest in K-files group. The changes of working length after root preparation in the three groups showed no significant difference (P > 0.05). Mtwo nickel-titanium rotary instruments and K3 nickel-titanium rotary instruments are have high efficacy and strong shaping ability in preparing curved root canals.
