Objective To observe the effects of vitrectomy combined with endotamponade on severe endophthalmitis. Methods The clinical data of 44 patients (44 eyes) of posttraumatic and 22 patients (22 eyes) of postoperative severe endophthalmitis were retrospectively analyzed. All patients were treated by vitrectomy and endotamponade. Intraocular foreign body removal (19 eyes), lens extraction (25 eyes), intraocular lens removal (six eyes) and scleral buckling (16 eyes) were performed. Tamponade with silicone oil (52 eyes) or C3F8 gas (14 eyes) was also performed. Postoperative follow-up ranged from two to 25 months, with the mean of 7-9 months. The visual acuity（VA）and intraocular pressure before and after surgery were comparatively analyzed. Results Inflammation of all the patients were controlled，the effective rate was 5.10%. There was no recurrence and retinal detachment. Among the 66 eyes, postoperative VA of 58 eyes (87.90%) increased,five eyes（7.60%）didn't change and three eyes（4.55%）decreased, the difference was statistically significant（chi;2=45.27，P＜0.05）. The postoperative intraocular pressure was higher than that before surgery，the difference was statistically significant（t=-3.23，P＜0.05）. Conclusions Vitrectomy combined with endotamponade is an effective way to cure severe endophthalmitis. It can improve the visual acuity and intraocular pressure.

目的 分析多功能空气消毒机在普通内科病房的动态消毒效果，为病房空气质量的控制提供参考依据。 方法 2010年9月－2011年4月对普通内科病房在动态状态下进行细菌检测并使用多功能空气消毒机消毒，并就消毒前后的空气细菌菌落总数进行分析比较。 结果 在动态状态下，病房关门关窗并开启空调机时，使用多功能空气消毒机消毒前的空气细菌菌落总数显著高于消毒后，差异有统计学意义（P＜0.05）；病房在开门开窗时，使用多功能空气消毒机消毒前后的空气细菌菌落总数比较，差异无统计学意义（P＞0.05）。 结论 普通内科病房在关门关窗并开启空调机动态状态下，使用多功能空气消毒机可以降低空气细菌菌落总数，改善房间空气质量。
An adaptive inertia weight particle swarm algorithm is proposed in this study to solve the local optimal problem with the method of traditional particle swarm optimization in the process of estimating magnetic resonance (MR) image bias field. An indicator measuring the degree of premature convergence was designed for the defect of traditional particle swarm optimization algorithm. The inertia weight was adjusted adaptively based on this indicator to ensure particle swarm to be optimized globally and to avoid it from falling into local optimum. The Legendre polynomial was used to fit bias field, the polynomial parameters were optimized globally, and finally the bias field was estimated and corrected. Compared to those with the improved entropy minimum algorithm, the entropy of corrected image was smaller and the estimated bias field was more accurate in this study. Then the corrected image was segmented and the segmentation accuracy obtained in this research was 10% higher than that with improved entropy minimum algorithm. This algorithm can be applied to the correction of MR image bias field.
ObjectiveTo evaluate the viability, short-term clinical efficacy, and safety of ultrasound-guided radioactive seed 125I permanent implantation in tissue in patients with advanced colorectal cancer. MethodsA total of 9 patients were recruited in this study. All of the patients came from China-Japan Union Hospital of Jilin University from October 2012 to October 2014, which had been selected after strict screening. Five cases of male patients, 4 cases of female patients; the age was between 46-78 years old, the median age was 54 years old. There were 5 cases of patients with pain. There were 14 lesions in total, 1 lesion was local tumor recurrence, 2 lesions were pelvic metastasis, 8 lesions were liver metastases, and 3 lesions were abdominal lymph node metastasis. CEA increased in 6 cases before implantation. All patients were confirmed metastasis by CT, MRI examination or pathology. The 125I radioactive seed implantation was guided by real-time ultrasound. CT scanning was taken in two months after treatment. The degree of pain relief, tumor local control, and the occurrence of complications were observed. ResultsIn 2 months after implantation of 125I radioactive particles, the CT scanning results showed that 2 cases obtained complete response (CR), 5 cases obtained partial response (PR), 1 case got stable disease (SD), and 1 case got progress disease (PD). Total effective was 7/9, and disease control was 8/9. Five cases with pain symptoms were relieved after treatment. One walk metal particle in the abdominal cavity was found by abdominal CT scanning in 1 case. There were no serious complications intraoperative and postoperative. ConclusionsUltrasound guided radioactive seeds 125I implantation in the treatment of advanced colorectal cancer can significantly relieve the clinical symptoms, improve the quality of life, and can effectively control the metastasis. It is safe and feasible, and the postoperative hospitalization time is short, it has the avantages of safety, effectiveness, and low incidence of complications.
Objective To study the disinfection effect of hand disinfectants containing alcohol after heating, and the comfortable feeling of using warm disinfectants among the medical staff in operation rooms. Methods Between November 2016 and January 2017, we analyzed the disinfection effect of two alcohol-containing hand disinfectants after heating in operation rooms through on-the-spot disinfection and inspection. Questionnaire was used to investigate the comfortable feeling of using warm hand disinfectants. Results After standing for 7 days at a temperature of 37℃, the major content of the two disinfectants decreased by less than 10%. Three minutes of disinfection by using the two kinds of disinfectants had an average natural-bacteria killing logarithm higher than 1.00, and they both had a qualified disinfection effect. Moreover, 96.7% of the medical personnel believed that warm disinfection products were more comfortable. Conclusion After heating, the two kinds of alcohol-containing hand disinfectants are effective in hand disinfection and more comfortable to use, which can improve hand hygiene compliance in surgical staff.
Objective To improve the knowledge of pulmonary mucormycosis through summarizing the clinical features and treatment of the disease. Methods A retrospective analysis was conducted on two cases of mucormycosis. The literature review was carried out with " pulmonary mucormycosis” as the research terms respectively in CNKI and Pubmed database. Search time ranged from January 2000 to June 2016. Results The first case was a 61-year-old male patient complained of cough, expectoration and dyspnea for 5 days. Chest computerized tomography (CT) showed lung nodules in the right upper lobe and bronchial cut off sign of apical bronchus. The patient received bronchoscopic examination and pathological findings indicated mucormycosis. Amphotericin B was recommended for the treatment. The patient recovered after treatment and was discharged. The second case was a 44-year-old female patient admitted to our hospital due to cough accompanied with expectoration and fever for over 10 days. Chest CT scan showed multiple double-pulmonary circular nodules and cavities with different sizes and clear boundary. The maximum cavity diameter was about 1.8cm, and the density of soft tissue was found in the part of the cavity. The patient received CT-guided percutaneous lung biopsy and pathological findings indicated fungal hyphae which was accorded with mucor infection. The patient received amphotericin B, voriconazole and posaconazole treatment, but with bad curative effect. She gave up therapy and died one week later after discharged. A total of 6 literatures were reviewed in above-mentioned databases. The clinical manifestations were nonspecific and the patients were likely to accompany with other diseases. The duration from the onset of symptoms to exact diagnosis was 37.5 days. Chest CT scan and pathological examination played important roles in the diagnosis of mucormycosis. Proper antifungal treatment could improve the prognosis. Conclusions Mucormycosis is a rare invasive fungal disease with high mortality. The clinical manifestations are nonspecific. Early diagnosis and appropriate treatment contribute to better prognosis.
