Methods Interpretation phenomenological analysis method was used in the study. Self- structured in- depth interviews were conducted with AD patients who were admitted to the hospital from November 2013 to February 2014, and combining the participation observation method to collect relevant data. Data were analyzed by content analysis. Results 16 cases were interviewed and four advanced themes were extracted: experience of disease symptoms; negative emotion; coping styles; the insight of life. Conclusions AD patients can produce complex psychological experiences when they are informed of the diagnosis because of the experience of pain, sudden critical illness, the role change and so on. Medical staff should pay attention to their psychological status and needs, take corresponding effective measures to promote the further treatment and their physical and psychological rehabilitation.

Objective To evaluate application of quality care in prevention of general surgery wound infection in elderly patients. Methods 116 cases of elderly patients undertook general surgery from October 2013 to October 2014 were selected in alphabetical order by pinyin of last name as the research objects, who were divided into the observation group (58 cases) and control group (58 cases) by lottery. The control group received routine care, the observation group received quality care. The occurrence of wound infection and the hospitalization time were compared. Results The incidence of wound infection of the observation group was 6.9%(4/58), which was lower than that of the control group [24.1%(14/58),χ2=6.576, P<0.05]. The hospitalization time of the observation group was lower than that of control group [(22.6±3.2) d vs.(28.6±3.8) d, t=5.401, P<0.05]. Conclusions Quality care contributes to reduce the incidence of wound infection on general surgery incisions of elderly patients, and promotes the recovery of patients.

Objective To evaluate the methodological quality of clinical trials on Chinese medicine interventional chemothera-py induced gastrointestinal toxic reactions from 2000 to 2014.Methods The randomized controlled trials(RCT)and semi-RCT on Chinese medicine interventional chemotherapy induced gastrointestinal toxic reactions were retrieved from the China National Knowledge Infrastructure (CNKI),Wanfang databases,VIP,China Biology Medicine Database (CBM)and Traditional Chinese Medicine (TCM)database by computer and supplemented by the manual retrieval (January 2000 to December 2014).The methodo-logical quality assessment on the included RCT and semi-RCT was conducted by using the Cochrane risk assessment table of bias. Results 291 articles were finally screened out,only 76 of RCT and semi-RCT were conformed to the at least one of low risk stand-ards of Cochrane risk assessment table of bias.Therefore the total methodological quality was not good enough.Conclusion The publishing of clinical trials on Chinese medicine interventional chemotherapy induced gastrointestinal toxic reactions shows the in-creasing trend year by year during the past 14 years.However,the different defects exist in the overall trial design.

BACKGROUND:During autologous tendon grafting, the ultimate tensile strength used for suturing the end of the ligament is important for successful surgery. Improving suturing strength and increasing the number of stitches is a good choice for increasing the fixed intensity. But excess amount of stitches can produce too many thread residues, thereby affecting tendon healing.
OBJECTIVE:To investigate the essential number of suturing pins for the anterior cruciate ligament revascularization in ligament end suture fixation to reduce suturing thread exposure.
METHODS:(1) In vitro biomechanics test:12 patel ar ligament specimens were divided into two groups:the specimens were sutured with 5 or 3 stitches using Krackow suture method. The suturing thread was J&J tendon suture thread. The strength of tensile was compared between the two groups by Tensile mechanical test was conducted to compare the strength of tensile between the two groups and to explore the optimal number of stitches and suturing method. (2) Clinical application:According to the results of in vitro experiments, modified Krackow suture method was used clinical y for arthroscopic anterior cruciate ligament reconstruction in 125 cases, including 62 cases receiving 3-stitch suture, and 63 cases undergoing 5-stitch suture.
RESULTS AND CONCLUSION:The fixed strength of tensile at suture sites was over 100 N for 3-stitch double-lock suture and 110 N for 5-stitch double-lock suture. There was no significant difference in the fixed strength between the two groups, but their strength values were both over the breaking strength of suturing materials. Moreover, the fixed strength could not be reduced by suturing throughout the ligament at the first stitch. Al the 125 cases were fol owed for 6.4 months averagely, and both 3-stitch and 5-stitch suture methods achieved good outcomes. The satisfaction rate was up to 99%, and no suture breakage or loosing occurred at early and late stages. These findings suggest that, using 3-stitch double-lock suture method, a satisfactory fixed strength can be achieved with reduced thread exposure. The suturing thread can run through the ligament at the first stitch, which can reduce thread exposure but not reduce the fixed strength.

BACKGROUND:Fewer ethical issues exist in adult stem cells, and some operating technologies are relatively mature. Therefore, to construct tissue-engineered salivary glands using adult stem cells is very attractive and seductive with an extremely important application prospect. OBJECTIVE:To establish a rat model of salivary gland injury by ligation of the main excretory duct of the submandibular gland and to explore the existing feasibility and location of adult stem cells in the injured models. METHODS:The main excretory duct of the right submandibular glands was ligated in Sprague-Dawley rats. After 1 week, rats were kil ed to remove the bilateral glands that were then subject to hematoxylin-eosin staining, PAS glycogen staining and immunohistochemical staining for determination of CK-19, Bcl-2, Ki-67. After that, we compared the normal submandibular gland with the damaged model after ligation of main excretory duct. RESULTS AND CONCLUSION:The rats showed differences in the volume and mass of the affected and normal submandibular glands. The normal submandibular gland was oval, ruddy, smooth, soft with an intact envelop. After ligation, the injured submandibular gland appeared to have atrophy with dark red in color, irregular morphology, envelop congestion, and rough texture;the surrounding vessels showed compensatory expansion. PAS-positive gland cells disappeared, CK-19-postive smal duct epithelial cells proliferated, and laminin-positive cells that were rarely found in the normal gland existed around the duct. In addition, Bcl-2/Ki-67 positive cells were both increased. These findings indicate that stem/progenitor cells may be located in the periductal area of the submandibular gland;and the model of submandibular gland injury established by ligation of the main excretory duct is effective to activate stem/progenitor cells in the submandibular gland.
