ObjectiveTo study the clinical characteristics of elderly hemodialysis (HD) patients and discuss how to control their complications, in order to improve their quality of life and lower their mortality rate. MethodContrastive study and analysis were performed on the clinical data of 98 maintenance HD patients (between elderly and young HD patients) between January 2013 and January 2014. Complications, rate of hospitalization and mortality were analyzed during the follow-up of one year. ResultsThe ratio of hypertensive kidney disease and diabetic nephropathy, as primary disease of the elderly HD patients, gradually increased. More people chose to use semi-permanent jugular vein catheter for elderly HD patients. Compared with young HD patients, the levels of hemoglobin, albumin, serum creatinine, KT/v were lower in the elderly patients, and C-reactive protein was much higher (P<0.05). There was no significant difference in cholesterol, triglyceride, calcium, phosphorus, parathormone between the two groups (P>0.05). Dialysis-related hypotension and blocking of vascular access occurred more frequently in elderly HD patients. Hospitalization rate and mortality rate were higher in elderly HD patients (P<0.05). ConclusionsImproving nutritional status, keeping vascular access unobstructed for a long time and decreasing complications related to hemodialysis are helpful for elderly HD patients to enhance their quality of life and reduce the mortality rate.
ObjectiveTo evaluate the clinical value of multi-slice CT in the diagnosis of complications due to breast augmentation. MethodsWe collected the imaging data of 32 female patients who accepted multi-slice CT examination in the second People's Hospital of Chengdu after breast augmentation between February 2010 and February 2015. The position, shape, edge, internal density, leakage, rupture and hard nodules of the prosthesis were observed and analyzed carefully. ResultsIn the 32 patients with breast augmentation, 12 were normal with bilateral symmetry and without abnormal shape or density. Among the other 20 patients, 11 had capsular contracture, 5 had prosthesis leakage, rupture and hard nodules, 4 had breast infection, 1 had fibroadenoma, 1 had cystoma, and 5 had little calcified nodules in the breast tissue. ConclusionThe multi-slice CT scan can clearly and accurately show the position, shape and size of the breast prosthesis as well as the existence of leakage, rupture and hard nodules in the prosthesis. It plays a very important role in the diagnosis of the complications due to breast augmentation and can be effective guidance for clinical operation.
Peripapillary intrachoroidal cavitation (PICC) is a common pathological change observed in high myopia. The exact pathogenesis of PICC is still unclear. Expansion and mechanical stretching of the peripapillary sclera, breakage and defect in the retina near the border of the myopic conus and communication between intrachoroidal cavity and the vitreous space may be important segments during the development of PICC. Color fundus photography shows a localized and well-circumscribed peripapillary lesion with yellow-orange colour, often accompanied by fundus changes, such as myopic conus excavation, optic disc tilting and inferotemporal retinal vein bending at the transition from the PICC to the myopic conus. However, the PICC lesion is not easy to be recognized in the fundus photography. Fluorescein angiography shows early hypofluorescence and later progressively staining in the lesion. Indocyanine green angiography shows hypofluorescence throughout the examination. Optical coherence tomography (OCT) is vital in diagnosing PICC. Hyporeflective cavities inside the choroid, sometimes communicating with the vitreous chamber, can be observed in OCT images. OCT angiography indicates lower vessel density or even absence of choriocapillary network inside or around PICC lesions.

Objective To investigate the application of transverse fascia in inguinal hernia repair. Methods In this study, 617 patients underwent inguinal hernia repair between January 1990 and December 2005 in our hospital were included, which were divided into two groups according to different operative ways: transverse fascia method group (n=337) and Bassini method group (n=280). Then intraoperative results, postoperative complications, and rehabilitated results of patients in two groups were compared. Results Compared with Bassini method group, the patients in transverse fascia method group did not show significant difference in operative time and blood loss during operation (Pgt;0.05). The differences of severe postoperative pain, testicular swelling, the time of the body’s restore for normal activities, and recurrence rate of patients between two groups were significant (Plt;0.05), while the difference of hematoma of scrotum and infection of incisional wound (Pgt;0.05). Conclusion The strengthening of posterior wall by transverse fascia and reconstruction of inner ring is a simple and effective method for inguinal hernia repair.
Objective To summarize the methods andskills of anterior cervical locking plate systems in clinical application and to analyze the causes of some complications as well as give some preventive or remedial countermeasures. Methods From 1998 to 2002, 159 patients with cervical spondylotic myelopathy,fracturedislocation,tumor or tuberculosis of the cervical spine were treated with anterior locking plate systems. The complications were reviewed and analyzed. Results Ten kinds of complications related to anterior locking plate systems occurred in 21 patients. Most of the complications were caused by improperly-selecting implants, experience and technique deficiency. Conclusio The important preventive or remedial countermeasures are correctly-selecting patients, meticulous preoperative preparation, properly-selecting implants, standard and skillful manipulation and rational postoperative protection.
ObjectiveTo evaluate donor safety in living donor liver transplantation. MethodsThe clinical data of 356 donors underwent living liver donation in our center from January 2001 to September 2015 were retrospectively analyzed. These patients were divided into pre-2008 group(before January 2008) and post-2008 group(after January 2008). The donor safety was evaluated with regard to three aspects, i.e. complications, liver function, and quality of life. Results①There was no donor death in our center.②The overall complications rate was 23.3%(83/356). The proportion of ClavienⅠ, Ⅱ, Ⅲ, andⅣcomplications was 50.6%(42/83), 26.5%(22/83), 21.7%(18/83), and 1.2%(1/83), respectively. In all the donors, the incidence of ClavienⅠ, Ⅱ, Ⅲ, andⅣcomplications was 11.8%(42/356), 6.2%(22/356), 5.1%(18/356), and 0.3%(1/356), respectively. The overall complications rate in the post-2008 group was significantly lower than that in the pre-2008 group〔18.1%(41/227) versus 32.6%(42/129), P < 0.01〕. The most common complication was the biliary complication with an incidence of 8.4%(30/356).③The postoperative liver dysfunction was transient and generally retur-ned to normal level within a week.④The donor's quality of life was generally satisfied as assessed by the SF-36 tool, and 94.8%(239/252) of them would donate again if necessary. ConclusionEver improving surgical and anesthetic techniques, together with strict donor selection and specialized perioperative management, could guarantee a low donor morbidity and a satisfactory long-term prognosis.
ObjectiveTo evaluate the macular visual function of patients with myopic choroidal neovascularization (MCNV) before and after intravitreal injection of conbercept.MethodsA prospective, uncontrolled and non-randomized study. From April 2017 to April 2018, 21 eyes of 21 patients diagnosed as MCNV in Shanxi Eye Hospital and treated with intravitreal injection of conbercept were included in this study. There were 9 males (9 eyes, 42.86%) and 12 females (12 eyes, 57.14%), with the mean age of 35.1±13.2 years. The mean diopter was −11.30±2.35 D and the mean axial length was 28.93±5.68 mm. All patients were treated with intravitreal injection of conbercept 0.05 ml (1+PRN). Regular follow-up was performed before and after treatment, and BCVA and MAIA micro-field examination were performed at each follow-up. BCVA, macular integrity index (MI), mean sensitivity (MS) and fixation status changes before and after treatment were comparatively analyzed. The fixation status was divided into three types: stable fixation, relatively unstable fixation, and unstable fixation. The paired-sample t-test was used to compare BCVA, MI and MS before and after treatment. The x2 test was used to compare the fixation status before and after treatment.ResultsDuring the observation period, the average number of injections was 3.5. The logMAR BCVA of the eyes before treatment and at 1, 3, and 6 months after treatment were 0.87±0.32, 0.68±0.23, 0.52±0.17, and 0.61±0.57, respectively; MI were 89.38±21.34, 88.87±17.91, 70.59±30.02, and 86.76±15.09, respectively; MS were 15.32±7.19, 21.35±8.89, 23.98±11.12, 22.32±9.04 dB, respectively. Compared with before treatment, BCVA (t=15.32, 18.65, 17.38; P＜0.01) and MS (t=4.08, 3.50, 4.26; P＜0.01) were significantly increased in the eyes 1, 3, and 6 months after treatment. There was no significant difference in the MI of the eyes before treatment and at 1, 3, and 6 months after treatment (t=0.60, 2.42, 2.58; P＞0.05). Before treatment and at 1, 3, and 6 months after treatment, the proportion of stable fixation were 28.57%, 38.10%, 38.10%, 33.33%;the proportion of relatively unstable fixation were 47.62%, 47.62%, 52.38%, 57.14% and the proportion of unstable fixation were 23.81%, 14.28%, 9.52%, 9.52%, respectively. The proportion of stable fixation and relatively unstable fixation at 1, 3 and 6 months after treatment were higher than that before treatment, but the difference was not statistically significant (x2=1.82, 1.24, 1.69; P＞0.05).ConclusionBCVA and MS are significantly increased in patients with MCNV after intravitreal injection of conbercept.
In the expert consensus published by the Pediatrics in 2013, it was first proposed that anti-VEGF drugs can be considered for retinopathy of prematurity (ROP) with stage 3, zone Ⅰ with plus disease. However, there are many problems worth the attention of ophthalmologists, including the advantages and disadvantages of anti-VEGF therapy compared with traditional laser therapy, systemic and ocular complications after anti-VEGF therapy, and what indicators are the end points of anti-VEGF therapy. Combined with this consensus and numerous research findings, we recommend that the first treatment for anti-VEGF or laser therapy should be considered from disease control effects. For the threshold and pre-threshold lesions, the effect of anti-VEGF therapy for zoneⅡ lesions is better than that for zone Ⅰ lesions and the single-time effective rate is high. So, it is suggested that anti-VEGF therapy should be preferred for the first treatment. The choice of repeat treatment should be considered from the final retinal structure and functional prognosis. Laser therapy is advisable for the abnormal vascular regression slower and abnormalities in the posterior pole. It can reduce the number of reexaminations and prolong the interval between re-examinations. However, the premature use of laser has an inevitable effect on peripheral vision field. Excluding the above problems, supplemental therapy can still choose anti-VEGF therapy again. Most of the children with twice anti-VEGF therapy are sufficient to control the disease. Anti-VEGF therapy should be terminated when there are signs such as plus regression, threshold or pre-threshold lesions controlled without recurrence, peripheral vascularization, etc.
