For choroidal neovascularization (CNV) secondary to pathological myopia, intravitreal injection of anti-VEGF has been widely used in clinic and achieved good outcome. However, due to the differences in the demographic characteristics, stages of disease progression and treatment procedure of CNV, the prognosis of the disease is variable. Complete ellipsoid band, smaller baseline choroidal neovascularization and better baseline vision are important predictors of good outcome of anti-vascular endothelial growth factor treatment. Chorioretinal atrophy or complications related to pathologic myopia indicate a poor prognosis. The influence of age, race, previous photodynamic therapy and early treatment on the prognosis of treatment need to be further studied.
OBJECTIVE: To investigate the feasibility of segmentation of latissimus dorsi on the basis of anatomy and electrophysiology. METHODS: Ten cadaveric latissimus dorsi was dissected according to the blood supply, nerve innervation. Electromyelogram (EMG) of latissimus dorsi of 13 healthy persons was recorded with superficial electrode plate in the motion of shoulder joint. The results of record were managed with statistic methods. Ten patients(including reconstruction of breast and repair of scar on elbow joint and on chest wall) were treated with the lateral inferior myocutaneous island flap. RESULTS: According to the medial and lateral vasculonervous branches, latissimus dorsi can be divided into the medial superior and lateral inferior segments. The clinical application of the segment achieved good results in reconstructing breast and in repairing scars on elbow and on chest wall. CONCLUSION: Latissimus dorsi can be divided into two segments and applied separately. The lateral inferior segment is more useful in shoulder motion.
To study the effect of intraperitoneal hyperthermic double distiled water and cis-diamminedichloro-platinum(DDP) perfusion to the peritoneal cancerous ascites,intraperitoneal injection of H22 cancer cells (2×107 tumor cell,each mouse) were performed in LACA mice. Five days after cancer cells injection, intraperitoneal perfusion of simple hypertherrnic (43℃) double distiled water(group Ⅰ) isotonic fluid (group Ⅱ ). DDP (group Ⅲ ), and hypertherrnic double distiles water perfusion combined with DDP (guoup Ⅳ ) were performed .The results showed that cancer cells in the peritoneal cavity of LACA mice were seriously damaged, the production of ascites was markedly inhibited and the survival days of LACA mice were prolonged in all groups . .The intraperitoneal hyperthermic double distilled water perfusion with DDP group showed more effective result as compared with the other groups,Only 1 peritoneal implanted dissemination was found after treatment in this group,Basing on the experimental from September 1991 through September 1993,intraperitoneal hyperthermic double distiled water perfusion with DDP was used to treat 32 advanced gastric cancer patients after radical gastrectomy with satisfactory results.
OBJECTIVE To review the physiological function of sodium hyaluronate in joints and its clinical applications. METHODS Many literatures were reviewed and analysed on therapeutic mechanism and the application foreground of sodium hyaluronate. RESULTS Extrinsic sodium hyaluronate plays an important role in improving synovial fluid and protecting cartilages as well as suppressing inflammation, so it is used in the treatment of joint diseases such as knee osteoarthritis, rheumatoid arthritis or temporomandibular osteoarthritis. CONCLUSION Sodium hyaluronate possesses a good applied prospect in joint diseases.
Objective To evaluate the clinical short-term efficacy and safety of application of glucocorticoids (GCs) before major abdominal surgery. Methods The randomized controlled trials (RCTs) on application of GCs before major elective abdominal surgery were systematically and comprehensively searched in Medline (1966–2022), Embase (1947–2022), Web of Science, and PubMed databases, and systematic review and meta-analysis of the included studies were performed to explore the effects of application of GCs before major abdominal surgery on postoperative complication, hospital stay, and serum interleukin-6 level. Results Nineteen moderate quality RCTs with 1 535 patients were finally included in the analysis. Preoperative application of GCs reduced postoperative IL-6 level [MD=–51.00, 95%CI (–62.36, –39.63), P<0.001], reduced postoperative complications [OR=0.53, 95%CI (0.35, 0.81), P=0.003], shorten hospital stay [MD=–0.64, 95%CI (–1.04, –0.24), P=0.002], and reduced the occurrence of infectious complications [OR=0.50, 95%CI (0.36, 0.70), P<0.01]. However, there were no statistically significant difference in incidence of anastomotic leakage [OR=1.15, 95%CI (0.43, 3.04), P=0.780] and bile leakage [OR=1.95, 95%CI (0.76, 5.00), P=0.170]. Conclusion Preoperative application of GCs can reduce the level of IL-6, reduce complications after major abdominal surgery and shorten postoperative hospital stay.
Objective To describe the design and application of an emergency response mobile phone-based information system for infectious disease reporting. Methods Software engineering and business modeling were used to design and develope the emergency response mobile phone-based information system for infectious disease reporting. Results Seven days after the initiation of the reporting system, the reporting rate in the earthquake zone reached the level of the same period in 2007, using the mobile phone-based information system. Surveillance of the weekly report on morbidity in the earthquake zone after the initiation of the mobile phone reporting system showed the same trend as the previous three years. Conclusion The emergency response mobile phone-based information system for infectious disease reporting was an effective solution to transmit urgently needed reports and manage communicable disease surveillance information. This assured the consistency of disease surveillance and facilitated sensitive, accurate, and timely disease surveillance. It is an important backup for the internet-based direct reporting system for communicable disease.
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.
Objective To review the current research progress of three-dimensional (3-D) printing technique in foot and ankle surgery. Methods Recent literature associated with the clinical application of 3-D printing technique in the field of medicine, especially in foot and ankle surgery was reviewed, summarized, and analyzed. Results At present, 3-D printing technique has been applied in foot and ankle fracture, segmental bone defect, orthosis, corrective surgery, reparative and reconstructive surgery which showed satisfactory effectiveness. Currently, there are no randomized controlled trials and the medium to long term follow-up is necessary. Conclusion The printing materials, time, cost, medical ethics, and multi-disciplinary team restricted the application of 3-D printing technique, but it is still a promising technique in foot and ankle surgery.
