Objective To investigate the prevalence of high myopia，the prevalence and risk factors of high myopia associated with chorioretinopathy in residents aged 60 years or over in Beixinjing community, Shanghai, China.Methods A cluster stratified random sampling method was used to screen 4153 people aged 60 and over in Beixinjing community. There were 3851participants in total with a 9273% response rate. Participants were invited to complete a questionnaire and received a comprehensive eye examination including visual acuity, refraction, slitlamp microscopic examination, direct ophthalmoscopy and fundus photography and so on. Spherical equivalent (SE) was used to determine the degree of refractive errors. The diagnosis of high myopic chorioretinopathy was made if SEgt;-6.00 D and myopic chorioretinal atrophy lesions were presented such as posterior scleral staphyloma, lacquer cracks, Fuchs spot and myopic arc spots. The degree of visual acuity impairment was determined according to the World Health Organization (WHO) classification as low vision (the best corrected visual acuity ge; 0.05, but lt;0.3) or blindness (the best corrected visual acuity lt;0.05).Results There were 207/3851(5.37%) high myopia patients, in which 183/207 (88.40%) patients were associated with myopic chorioretinopathy. The prevalence of myopic chorioretinopathy decreased while age increased (chi;2=19.21, Plt;0.01), but statistically there was no gender difference （chi;2=1.83, Pgt;0.05）. Logistic regression analysis showed that there were significant differences in the prevalence of high myopia between people with different age, educational levels and family history （chi;2=19.21，32.08，960.68；Plt;0.01）.There were 29 cases of bilateral blindness, 96 cases of unilateral blindness,104 cases of bilateral low vision and 562 cases of unilateral low vision in those participants. In 183 cases of high myopic chorioretinopathy patients, 111（60.65 %）cases had an obvious visual impairment, including 3448% (10 cases) of bilateral blindness, 1146% (11 cases) of unilateral blindness, 2981% (31 cases)of bilateral low vision and 1050% (59 cases) of unilateral low vision.Conclusions The prevalence of high myopia of residents aged ge;60 years in Beixinjing community, Shanghai,China is relatively high. Age, education level and family history are the most important factors affecting the occurrence of chorioretinopathy in high myopia patients.
ObjectiveTo investigate the efficacy and safety of bortezomib combined with dexamethasone and thalidomide regimens on aged patients with multiple myeloma. MethodsA total of 166 multiple myeloma patients were selected between January 2009 and June 2013; all patients were assigned to regimens of T-VD or T-VAD named T-VD group or T-VAD group (with 25 patients in T-VD group and 29 in T-VAD group). Efficacies and toxicities were analyzed and compared after two cycles. ResultsOverall response rate (OR) in T-VD group was 84.0%; there was 6 patients achieved complete response (OR) or very good partial response (VGPR) (24.0%). However, Overall response rate (OR) in T-VAD group was 48.3%; there was only one patient achieved CR or VGPR (3.4%); significant difference between two groups was found (χ2=7.513, P<0.05). The major adverse reactions were debilitation, nausea, vomiting, myelo-suppression, cardiac toxicity, and peripheral neuropathy. There were highest incidence of nausea and vomiting in T-VAD group compared to T-VD group (χ2=5.794, P<0.05). ConclusionBortezomib combined with dexamethasone and thalidomide regimens is effective and safe, which can be widely used for aged patients with multiple myeloma.
【Abstract】ObjectiveTo investigate whether heme oxygenase-1 can alleviate the ischemiareperfusion injury of the aged donor liver. MethodsThe activity of superoxide dismutase (SOD) and catalase (CAT), and the contents of tocopherol (Vit E), ascorbic acid (Vit C) and malondialdehyde (MDA) were measured in the livers of adult SD rats (n=5) and aged SD rats (n=5). The experimental aged donor group (n=30) received intraperitoneal injection of Hemin 24 hours before operation, the control aged donor group(n=30) received saline. The histologic changes and apoptosis in the donor liver were observed. ResultsThe activity of SOD and the contents of Vit E and Vit C decreased significantly in 5 aged rats（P＜0.05）, but the content of MDA increased（P＜0.05）. Before the harvesting of the grafts, the activity of SOD and the contents of Vit E and Vit C increased significantly in rats pretreated with Hemin （P＜0.05） and the content of MDA decreased（P＜0.05）. The apoptotic cells in the livers pretreated with Hemin also decreased significantly after reperfusion（P＜0.05）. ConclusionThe liver of aged rat presents oxidative stress and peroxidative state. Ischemia-reperfusion injury can be alleviated by the induction of HO-1.
Objective To evaluate the effectiveness and the value of balloon kyphoplasty in treating aged osteoporosis thoracolumbar vertebrae burst fracture. Methods Between January 2003 and January 2008, 36 thoracolumbar vertebrae burst fracture patients were treated. There were 15 males and 21 females with an average age of 65.4 years (range, 59-72 years). Fourteen cases had no obvious history of trauma, 19 had a history of sl ight trauma, and 3 had a history of severe trauma. Forty vertebral bodies were involved, including 1 T7, 3 T9, 8 T10, 10 T12, 9 L1, 7 L2, and 2 L4. All patients displayed local pain and osteoporosis by bone density measurement with no neurological symptom of both lower limbs. Balloon kyphoplasty through unilateral (31 cases) or bilateral (5 cases) vertebral pedicles with polymethylmethacrylate was performed at the injection volume of (3.46 ± 0.86) mL per vertebral body. Before and after operation, the anterior height and posterior height of fractured vertebral body and the sagittal displacement were measured. Results Two cases had intraoperative cerebrospinal fluid leakage; 1 case had no remission of waist-back pain and pain was released after symptomatic treatment. All 36 patients were followed up 2.3 years on average (range, 1.5-4.0 years). No cement leakage was found with good diffusion of cement on X-ray film. The restoration of the height of vertebral bodies was satisfactory without nerve compression symptoms and other compl ications. The Visual Analogue Score at last follow-up (2.34 ± 1.03) was significantly lower than that of preoperation (6.78 ± 1.21), (P lt; 0.05). The compressive percentage of anterior height (19.80% ± 1.03%) of fractured vertebral body after operation was significantly lower than that before operation(25.30% ± 2.50%), (P lt; 0.05). There was no significant difference in posterior compressive percentage and sagittal displacement between pre- and post- operation (P gt; 0.05). Conclusion Based on roentgenographic scores, balloon kyphoplasty is selectively used to treat aged osteoporosis thoracolumbar vertebrae burst fracture, and the radiographic and cl inical results were satisfactory.
Objective To summarize the experience of sequentially minimally invasive treatment for aged and high risk symptomatic pancreatic pseudocyst under ultrasound guided percutaneous catheter drainage combined with endoscopic technique. Methods The clinical data of 30 patients with aged and high risk pancreatic pseudocyst treated from January 2009 to January 2012 in this hospital were analyzed retrospectively. Results Percutaneous tubes were successfully placed in 30 patients， cystic liquid was sufficiently drained， and the compression symptom of cyst was relieved immediately. After stable disease， 12 patients with communicating cysts were diagnosed by using endoscopic retrograde cholangiopancreatography. Pancreatic duct stents were inserted in 12 patients with communicating cysts for 60-90d （with an average 70d） after endoscopic sphincterectomy and endoscopic pancreatic sphincterectomy. Cysts disappeared in the other 18 cases receiving external drainage with external drainage tubes， the drainage time was 15-90 d with an average 30d. Neither recurrence nor complications were found in all the cases during 12-21 months （with an average 18 months） follow-up. Conclusion Interventional ultrasound combined with endoscopic technique sequentially minimally invasive treatment for aged and high risk symptomatic pancreatic pseudocyst has superiorities in little trauma， fewer complications， and exact effect.
Flicker and photopic eletroretinogram(ERG)were recorded for 45 eyes of dry type of age-related macular degeneration(AMD)and 24 eyes of wet type of AMD respectively,the amplitud and phase of fundamental response compomeng(30Hz)by discrete Fourier tranform(DFT)were analysed.The abnormality ratios of phases and amplitudes in fundamental responses,amplitudes of photopic white or red b-waves were 48.89%,8.89%,10.11% and 8.89% respectively.The visual acuities of 24 eyes were 1.0 or better,the abnormality ratios of phases were up to 37.50%.These suggest that the change of phases is a sensitive method for detecting the early abnormality of visual function in AMD.The abnormality ratios of phases and amplitudes in fundamental responses were 62.5% and 45.84% in wet type of AMD.The differences between dry type and wet type in amplitudes of fundamental responses and photopic b-waves were statistically significant(P＜0.01).This shows that the change of amplitudes is associated with the degree of pathological change of AMD. （Chin J Ocul Fundus Dis,1996,12: 41-43）
ObjectiveTo evaluate the reading speed and related factors of normally-sighted middle-aged and elderly people, and compare with those assessed in age-related macular degeneration (AMD) patients.MethodsProspective case control study. Participants aged 45 to 85 years old with junior high school or above education and BCVA no less than 0.6 from the community around the First Hospital of Tsinghua University were recruited. People with ocular and nervous system diseases were excluded. AMD patients without other ocular and nervous system diseases, with the BCVA of their better eye above 0.05, were recruited from the Low Vision Clinic of the First Hospital of Tsinghua University. The best corrected vision, contrast sensitivity, and reading acuity were tested. Reading speed was evaluated with IReST Chinese version. Single factor correlation analysis was used to assess different factors which may be related with the reading speed, then multiple linear regression analysis was conducted further.ResultsFrom January to April, 2016, 53 volunteers aged 60.7±8.8 years old participated in the survey including 17 males and 36 females. Their median of best vision acuity both distance and near was 1.0, and their average reading speed was 244±55 characters/min. The average reading speed of younger participants in the middle-aged group (45-59 years old) was statistically faster (P＜0.05) than the elderly group (≥60 years old), which was 267±53 and 227±51 characters/min separately. The reading speed was correlated with age (r=－0.476, P=0.000), gender (t=－2.291, P=0.031), educational level (t=2.656, P=0.011), reading habits (t=7.346, P=0.000), best corrected distance vision (r=－0.293, P=0.033), best corrected near vision (r=－0.460, P=0.001), and reading acuity (r=－0.558, P=0.000) by single factor correlation analysis. Further analysis with multiple linear regression showed that reading acuity, gender, education level, and reading habits were significantly correlated with reading speed (β=－283.312, 28.303, －37.700, －45.505; P=0.000, 0.022, 0.019, 0.023). Totally 22 AMD patients aged 77.4±8.2 (59-90) years old joined the study from September 2016 to August 2018, including 16 males and 6 females. The median reading speed was 118 characters/min. Compared with the normally-sighted elderly, there were more males in AMD patients (χ2=3.981, P=0.046). They were older (t=－4.285, P=0.000), with significant poorer visual acuity (t=-6.176, P=0.000) and lower reading speed (t=-5.719, P=0.000). Significant correlation was found between reading speed and best binocular distance or near vision, reading acuity and contrast sensitivity (r=－0.771, －0.805, －0.776, 0.511; P=0.000, 0.000, 0.000, 0.015), no statistic relationship was found between reading speed and age(r=0.021, P=0.926) or gender(Z=－0.382, P=0.703) in AMD patients.ConclusionsThe reading speed of normally-sighted people declined with age. Reading acuity may be a better predictive factor than distance vision for reading function. Compared with normally-sighted group, the reading acuity and reading speed of AMD patients was significantly lower. The main factor affecting their reading speed was the severity of their visual impairment.
Objective To explore the clinical effect and complications of lumbar plexus block through different approaches on perioperative analgesia in aged proximal femur surgery, and find the best method for analgesia in these patients. Methods From January to December 2015, 150 elderly patients scheduled for proximal femur surgery were randomly divided into three groups: psoas compartment block (PCB group, n=50), Winnie " 3 in 1” block (Winnie group, n=50), and fascia iliaca compartment block (FICB group, n=50). Twelve hours before surgery, guided by ultrasound and nerve stimulator, lumbar plexus blocks were performed in all the patients, then patient-controlled analgesia (the formula and the usage were the same) was done. All patients received epidural anesthesia, and were maintained postoperative analgesia for 72 hours. If Rest Visual Analogue Scale>3 or Initiative Movement Visual Analogue Scale>4, sufentanyl 10 μgi.m. was given. Muscle strength grades and complications were recorded. Anesthetic effect of sensory block of femoral, lateral femoral cutaneous, and obturator nerves were measured and recorded too. Results There were two cases of epidural block, and one case of puncture point bleeding in group PCB; no complication in the other groups was found. There was no remedy for inadequate analgesia in the three groups. Compared with group PCB, the muscle strength grades during postoperative 24–72 hours in group FICB were higher (P<0.05). The successful rate of the block of lateral femoral cutaneous nerves was 64%, 91% and 96% in group Winnie, group PCB and group FICB, respectively, and the differences between the three groups were all statistically significant (P<0.05). The successful rate of the block of obturator nerves in group FICB (62%) was lower than that in group PCB (89%) and Winnie group (84%) (P<0.05). Conclusion Continuous fascia iliaca compartment block on perioperative analgesia in aged proximal femur surgery, with exact effect, less complications and simple operation, is better than the psoas compartment block and Winne " 3 in 1” nerve block.
Objective To evaluate the effect of minimally invasive dynamic hip screws (MIDHS) in treating aged intertrochanteric fractures. Methods From April 2006 to March 2008, 49 aged patients with intertrochanteric fractures were treated with MIDHS. There were 22 males and 27 females, aged 65-78 years (average 70.2 years). Frature was caused by trafficaccident in 7 cases, by fall ing from height in 3 cases, and by injury from fall in 39 cases. The time from injury to operation was 2-12 days (average 5.5 days). According to Evans classification, there were 28 cases of types I, II (stable fracture) and 21 cases of types III, IV (unstable fracture). If the Singh index≤3 was defined as osteoporosis, the osteoporotic rate was 71.4% (35/49). All patients were on a radiolucent fracture traction table and their fractures had satisfactory closed reduction. After the guide wire was inserted and reamed under fluoroscopy, the lag screw and side plate were introduced through the small incision. In all unstable fractures, an additional, antirotational and large cancellous bone screw was used cranial to the DHS. Results The average operation time was 65.2 minutes. The average blood loss was 189.3 mL. All patients had satisfactory reduction and 79.6% (39/49) had adequate lag screw positions. The average postoperative hospital ization days was 5.8 days (3-12 days). All incision healed at stage I. There was no postoperative complications. Forty-nine patients were followed up 12 to 30 months (average 19.8 months). Fractures healed within 16 weeks in 47 patients and the average healing time was 13.1 weeks (12-16 weeks). The average Harris scoring was 90.8 (75-95). Implant failure and nonunion occurred in 2 cases, no serious compl ication occurred in other patients. Conclusion The MIDHS is a simple, safe and effective method for treatment of aged intertrochanteric fractures.
