Methods A total of 175 local nurses and 175 nonlocal nurses were randomly selected and investigated by SSRS and the earthquake questionnaire. Results There were no significant differences in their knowledge about the earthquake, professional identity and action (Pgt;0.05). The total and the three dimensions scores of SSRS of the two groups were lower than those of the domestic norms (Plt;0.01) except the subjective support dimensions. The total scores, objective support and subjective support dimensions scores of nonlocal group were higher than that in the local group (Plt;0.01). In coping style questionaire, there were significant differences in solving problems and retreat factor(Plt;0.01)and no significant differences in remorse, salvation and illusion(Pgt;0.05). Conclusion The earthquake affected mental health of the nurses and their psychological state need to be much concerned,especially the nonlocal ones.
Patients with brain metastases are more prone to developing life-threatening neurological symptoms. Initial therapies include surgery, whole brain radiotherapy (WBRT), and stereotactic radiotherapy. With the progress of stereotactic radiotherapy, the indication of stereotactic radiosurgery (SRS) is gradually expanding, and the indications for surgery and WBRT gradually narrowed. The existing studies have shown that SRS can significantly benefit patients who are <50 years old with single brain metastasis, but the specific scope of the application with SRS is still controversial, and a large number of the phase Ⅲ randomized multicenter trials designed around the controversies are also developing. This review summarizes the results of clinical research and came to the conclusion. Firstly, postoperative adjuvant SRS in the treatment of brain metastases is superior to postoperative adjuvant WBRT. Secondly, using SRS in the elderly patients with multiple brain metastases are safe and effective. Thirdly, the use of targeted therapy in patients with brain metastases thereby delaying SRS may lead to poor prognosis. The focus of future research include selection of optimal timing for adjuvant targeted therapy after SRS and the appropriate patient population, as well as prevention of recurrence and metastasis after lacal treatment.

Results The surgical combined treatment for local recurrence of rectal cancer can markedly improve the survival ratio. Conclusion The surgical combined management of local recurrence of rectal cancer after anterior resection should be performed. The active and effective surgical combined management may help prolong the survival time and improve life quality.
Low-intensity ultrasound stimulation of the retina has the ability to modulate neural activity in the primary visual cortex (V1), however, it is currently unclear how different intensities and durations of ultrasonic stimulation of the retina modulate neural activity in V1. In this paper, we recorded local field potential (LFP) signals in the V1 brain region of mice under different ultrasound intensities and different stimulation times. The amplitude of LFP corresponding to 1 s before ultrasound stimulation to 2 s after stimulation (–1–2 s) was analyzed, including the power and sample entropy of delta, theta, alpha beta, and low gamma frequency bands. The experimental results showed that, as the stimulation intensity increased, the peak value of the LFP in the visual cortex showed a linear upward trend; the power in the delta and theta frequency bands showed a linear upward trend, and the sample entropy showed a linear downward trend. With increases of stimulation duration, the peak value of the LFP in the visual cortex showed an upward trend, and the upward trend gradually weakened; the power in the delta frequency band showed an upward trend, the sample entropy showed a linear upward trend, and the sample entropy in the theta frequency band showed a downward trend. The results show that low-intensity ultrasonic stimulation of the retina has a significant modulatory effect on neural activity in the visual cortex. The study provides insights into the mechanisms by which ultrasonic stimulation regulates visual system function. Furthermore, it clarifies the patterns of parameter selection, facilitating the development of personalized multi-parameter modulation for the treatment of visual neural degeneration, retinal disorders and related research areas.

Methods A total of 1200 cases who need cesarean section were randomly divided into 3 groups (400 cases in each group): simple local anesthesia group (group L), droperidolfentanyl strengthen local anesthesia group (group F) and analgestic and amnestic anesthesia group (group J). Group L was only local anesthesia. Group F was local anesthesia supplemented by droperidol 500 mg, fentanyl 015 mg. Group J was supplemented with ketamine on the basis of group F. Then the time from anesthesia to the fetus delivery, Neonatal Apgar score of one and five minutes, the blood pressure fluctuations, amount of bleeding in or after surgery and the satisfaction of anesthesia were all observed. Results Compared with group L and F, the delivery time was no significant difference, Apgar score increased, blood pressure fluctuations in pregnant women was not obviously varied, amount of bleeding in or after surgery had no significantly increase, and the satisfaction of anesthesia improved markedly all in group J. Conclusions The analgestic and amnestic anesthesia assisted by lowdose ketamine, in cesarean section, is better than local anesthesia and strengthen local anesthesia by droperidolfentanyl, which is worthy to be popularized, especially in emergency caesarean section.
Objective
To investigate the efficacy and safety of ultrasound-guided TAP block for the anesthesia in peritoneal dialysis (PD) catheter implantation.
Methods
Patients with end-stage renal disease who intended to receive PD catheter implantation in the West China Hospital of Sichuan University were enrolled from April 2015 to February 2016. Those who met the inclusion criteria were randomly divided into two groups: the local filtration anesthesia (LF) group and the TAP group. The two groups got the ultrasound guided TAP block (The LF group got a shame TAP block by making the skin wheal and just inserting the needle into the TAP with the guidance of ultrasound), then the LF group received local filtration anesthesia twenty minutes later, with the TAP group had sham LF anesthesia by injection of saline at the incision subcutaneously. The anesthetist generated the random allocation sequence and performed all TAP/sham blocks according to the allocation of each patient. The patients, investigators were all blind to the allocation. The follow-up time was 3 months. The primary outcomes were the rate of alteration to general anesthesia and the VAS score during and after the surgery. The dosages of sufentanil for analgesia during and after were recorded. The satisfaction to the effect anesthesia by the operation doctors, PD catheter related complications and adverse events related to TAP block or anesthetic agent were also recorded. Statistic analysis was conducted using SPSS 19.0 software.
Results
A total of 36 patients were included, 12 cases in the LF group and 24 cases in the TAP group. The rate of alteration to general anesthesia in the TAP group was 4.12% and was significantly lower than that in the LF group (33.3%) (P=0.034). The VAS scores at the time points of incision of skin, division of subcutaneous tissue and anterior rectus sheath, opening the peritoneum, insertion of PDC, suture of skin, 2 hours and 24 hours after operation were significantly lower in the TAP group compared to the LF group (P values=0.001, 0.037, 0.000, 0.001, 0.029, 0.035, and 0.000, respectively). The TAP group consumed less sufentanil during the operation and showed a higher satisfaction of the operation doctors. There were no significant differences in the PD catheter related complications and adverse events between the two groups.
Conclusion
The ultrasound-guided TAP block can be an effective and safe anesthesia method for PD catheter implantation. Because of the limitation of small sample size of this study, a multiple center study with larger sample size is suggested.
Objective To approach the surgical therapeutic efficacy of local recurrence of rectal cancer. Methods Fifty-six patients with local recurrence of rectal cancer suffered from reoperation from January 2003 to January2011 in this hospital were collected. Chi-square test was performed to analyze the complete excision rates of reoperation for different recurrent time after radical resection and different surgical procedures after primary radical resection of rectalcancer. The method of log-rank test was used for survival analysis of the Miles and Dixon procedure. Results ①The opera-tion time and intraoperative bleeding of reoperation for local recurrence of rectal cancer were more than those of the primary radical resection of rectal cancer （P＜0.05）. ②The complete resection rate of the local recurrence of rectal cancer in 5 years after primary radical resection of rectal cancer was higher than that of the local recurrence of rectal cancer within 2 years after primary radical resection of rectal cancer， and the difference was statistically significant （P＜0.01）. ③The complete resection rate of the local recurrence of rectal cancer of the technique of Dixon in the primary radical resection of rectal cancer was higher than that of Miles， and the difference was statistically significant （P＜0.05）. ④The median survival time and 2-year survival rate and 5-year survival rate of the technique of Dixon in the reoperation were longer or higher than those of Miles， and the differences were statistically significant （P＜0.05）. Conclusions Surgical procedure and postoperative recurrence time after primary operation can both influence complete excision rate of reoperation for local recurrence of rectal cancer. And reoperation for local recurrence of rectal cancer can prolong the survival time.
Chitosan is a kind of biological material with good histocompatibility and gradual biodegradability in vivo. It has no toxicity or side-effect. For its gradual degradation, chitosan and adriamycin were mixed and formed drug delivery system (DDS). The release test of DDS and exudant of DDS in inhibiting OS-116 were examined in vitro. The results were as following: the DDS could release adriamycin in slow and stable way. The SO-116 inhidition rate of the exudant of the DDS on the 1st, 20th, 40th and 60th day was 58.11%, 36.48%, 24.32% and 21.62% respectively. It was concluded that the drug delivery system was a slow release system. It could maintain the concentration of adriamycin in a certain level. It was also suggested that the chitosan was a good carrier for slow release of chemotherapeutic drug in local therapy for postoperative treatment of bone tumor.
Objective To introduce the experience and comprehensionto reconstruct nasal defect after tumor excision. Methods FromApril 1996 to April 2006, based on the aesthetic subunit principle and according to the size, shape, location of nasal defect and the conditions of surrounding skin, homologous local flap was selected to cover the nasal defect in 428 cases which nasal tumors were removed. Among 428 cases, there were 273 men and 155 women, with a median age of 52 years (12-78 years); including 146 cases of basal cell carcinoma, 83 cases of squamous cell carcinoma, 54 cases of epidermal cyst, and 145 cases of pigmented naevus.The clinical stage of malignant tumor was 0-Ⅰstage, the course of disease was 1 week to 3 months. The locations were nasal tip in 51 cases, nasal ala in 102 cases, dorsum of nose in 138 cases, and nasal side in 137 cases, across 2 nasal subunits in 83 cases. The area of thedefect ranged between 0.6 cm×0.6 cm and 3.0 cm×4.0 cm. The origin of flaps was frontonasal flap in 58 cases, bilobed flap in 67 cases, reforming rhomboid flap in 152 cases, nasolabial flap in 118 cses, forehead falp in 33 cases. The secondary defect of donor site was directly sutured. Results Among 428 cases, 423 cases acquired complete recovery; 3 cases which had epiderm necrosis over the far end of the flap achieved healing by the first intention and 2 cases which had suffered low-grade infection of incision achieved healing by the second intention after regional change dressings.The nasal defect was successfully repaired in all patients,and the all flaps survived. A total of 385 patients were available forfollow-up of 1 to 60 months, no tumor recurrence occurred, and the repaired tissue were good match with surrounding tissue, good nasal contour was obtained, the cosmetic results were satisfactory. Conclusion Based on the nasal aesthetic subunit principle, the local flap can reconstruct the nasal above medial defect, and a good color, contour and texture match with the surrounding skin can be obtained, the cosmetic results are satisfactory.
ObjectiveTo evaluate the impact of local infiltration analgesia on postoperative pain after hip arthroplasty.
MethodsRelevant randomized controlled trials comparing the analgesia effect and adverse effects between local infiltration analgesia group and non-local infiltration analgesia group (control group) were identified from Cochrane Library, Embase, PubMed, China National Knowledge Infrastructure, VIP database and Wanfang database from their establishment until May 2016. A systematic review was performed to compare the pain scores and adverse events between those two groups. Effective data were pooled for Meta-analysis with software RevMan 5.2.0.
ResultsTwelve eligible trials were identified in this study. The pain scores of the two groups of patients during rest time after surgery were significantly different[WMD=-19.06, 95%CI (-21.51, -16.62), P<0.000 01]; the pain scores were also significantly different during activity time[WMD=-11.45, 95%CI (-15.56, -7.34), P<0.000 01]. There was significant difference in postoperative nausea and vomiting between the two groups[RR=0.59, 95%CI (0.42, 0.84), P=0.003]. The pain degree and incidence of nausea and vomiting in the local infiltration analgesia group were lower than the control group, but there was no significant difference between the two groups in terms of urinary retention, itch and hypotension (P>0.05).
ConclusionLocal infiltration analgesia is effective in reducing postoperative pain without any additional adverse reactions.
