MTT assay was presented in this paper and used in 3 cases of retinoblastoma afert enucleation to evaluate the clinical effect of different chemotherapeutic agents.The results showed that the sensitivity of anticancer agents were various in different cases of retinoblastoma.The combining treatment of tow anticacer agents together was seemingly preferable to a single use.When a single drug was chosen,it was advisable to use carboplatin,cisplatin,mitomycin C or etopside.If a combination of 2 anticancer drugs were applied,vincristin with carboplatin or cisplatin will give a better effect than others,but vincristin is not sensitive when applied alone. （Chin J Ocul Fundus Dis,1993,9:207-209）
Age-related macular degeneration (AMD) is an age-related neurodegenerative eye disease characterized by degeneration and progressive death of retinal pigment epithelium (RPE) and photoreceptor cells. In recent years, as a new treatment for AMD, stem cell therapy has attracted wide attention in the field of AMD, and has become a current research hotspot. Although stem cell therapy carries risks such as increased incidence of cancer and immune rejection, it significantly promotes damaged photoreceptor cells and retinal cells by differentiating into RPE cells and other retinal cell types, as well as secreting neurotrophic factors and extracellular vesicles. In particular, the development of embryonic stem cell-derived RPE cells, its cryopreservation technology and the advancement of plasmid, adeno-associated virus, Sendai virus and other delivery technologies have laid a solid foundation for stem cell therapy of AMD. As a new method to prevent retinal damage and photoreceptor degeneration, stem cell neuroprotective therapy has shown great potential, and with the continuous maturity and improvement of these technologies, stem cell therapy is expected to provide new ideas for the prevention and treatment of AMD in the future.
Objectives To assess the effectiveness and safety of any form of therapy compared with glucocorticoid for the treatment of oral lichen planus. Method The Cochrane Library (Issue 4, 2007), MEDLINE (1966-2007), EMbase (1966-2007), CBM (1978-2005), CNKI (1989-2007), and VIP (1989-2007) were searched for randomized controlled trials or quasi-randomized controlled trials. Quality assessment and data extraction were performed by two reviewers independently. Meta-analysis was performed for the results of homogeneous studies by RevMan 4.2.9 software.Results Finally, 14 studies involving 9 therapy methods were included. Four studies were concerned with cyclosporine.We performed a meta-analysis of 3 studies. The results showed there was no statistically significant difference in the curative effect of cyclosporine and the steroid with RR 2.94 and 95%CI 1.03 to 9.97. The results showed that the curative effect of total glucosides of paenia plus topical application of triamcinolone acetonide (RR0.21, 95%CI 0.10 to 0.44),tacrolimu (RR 0.18 and 95%CI 0.05 to 0.72), and pimecrolimus (WMD –0.50 and 95%CI –0.85 to –0.15) were better than glucocorticoid. There was a statistically significant difference between fluocinolone acetonide and retinoic acid in terms of curative effect with RR 3.20 and 95%CI 1.03 to 9.97. The curative effect of mesalazine (RR 0.42 and 95%CI 0.05 to 3.54), Mycostatin paste plus desamethasone paste (RR 1.23 and 95%CI 0.93 to 1.61), triamcinolone acetonide plus vitamin B12 ( RR 0.50 and 95%CI 0.05 to 4.94), chitin (RR 1.30 and 95%CI 0.86 to 1.96) was similar with that of glucocorticoid.Conclusion Statistical analysis showed the curative effect of total glucosides of paenia combined with triamcinoloneacetonide is better than glucocorticoid. Due to the mistakes of theincluded studies designs,,further high-quality,largescale randomized controlled trials are required to confirm the effectiveness and safety of this therapy method.
Objective To explore the clinical experience on treatment of thromboangitis obliterans (TAO) by embolectomy. Methods Fourteen of 121 patients with TAO treated in our hospital from March 2000 to March 2010 were included in this study. Total 14 limbs consisted of 2 upper extremities and 12 lower extremities. Among these cases, 8 cases underwent embolectomy and 6 cases received embolectomy combined the stem cell transplantation. Results Of 14 cases of TAO patients, 11 cases were successfully treated by surgery and 3 cases failed. After successful operation, patient’s pain disappeared and anklebrachial index improved obviously. Seven patients treated successfully by surgery were followed up from 5 months to 8.5 years (mean 4 years), in whom the intermittent claudication and rest pain disappeared in 4 cases, and disease deteriorated in 2 cases who always smoked, and one case had intermittent claudication who stopped smoking. For 3 cases patients failed to operation, one lost followup, one had to receive a below knee amputation due to keep smoking after operation, and one case who stopped smoking underwent alleviative symptoms for 3 years. Conclusion Embolectomy is a safe and effective technique for treating TAO.
Objective To study the cl inical features of infantile hemangioma and vascular malformation, to find out a proper strategy of deal ing with them. Methods From March 2000 to August 2007, 2 957 cases of infantile hemangioma and vascular malformation were treated, including 860 operative cases and 2 097 non-operative cases. There were 441 male and419 female patients in operation group, aging 6 months to 18 years (median 5 years). In 1 950 hemangioma patients of nonoperation group, there were 575 male and 1 375 female patients, aging 1 month to 14 years (median 6 months); in 147 vascular malformation patients of non-operation group, there 67 male and 80 female patients, aging 2 years to 17 years (median 7 years). In non-operative group, 147 vascular malformation patients and 1 525 infantile hemangioma patients were followed up without any medical intervention, while other 425 hemangioma patients recceived triamcinolone plus dexamethasone intralesional injection treatment. All the treatments and outcomes were recorded. Results Vascular malformation cases and infantile hemangioma cases presented totally different cl inical features. To the deadl ine of this study, 522 (34%) of 1 525 un-intervented hemangioma cases turned into involuted phase and 383 (90%) of 425 cases receiving triamcinolone plus dexamethasone intralesional injection treatment turned into involuted phase after injection treatment; no regression was noted in 147 cases of vascular malformation. The constituent ratio of infantile hemangioma in 860 operative cases was decreased gradually and the constituent ratio of vascular malformation was increased gradually as the age increasing. Conclusion Infantile hemangioma has a distinct l ife pattern. Except several specific cases need medical intervention for their special location or large ambit and unacceptable growth, most infantile hemangioma need no medical intervention. Most vascular malformations can not regress spontaneously, proper intervention is in need.
ObjectiveTo research on the clinical efficacy of gonadotropin releasing hormone (GnRH) pump in the treatment of hypogonadotropic hypogonadism (HH) by using micropulse pump subcutaneous pump Gonadorelin to treat patients with HH. MethodsThrough the report of one case of GnRH pump treatment patient and related literature review, we studied the effect of GnRH pump therapy and the traditional treatment on HH patients' sex hormone level, secondary sexual characteristics, spermatogenesis and pregnancy rate. ResultsThrough treatment, GnRH pump effectively improved the patient's sex hormone level, secondary sexual characteristics development and sperm production ability, and eventually the patient attained the goal of fertility. The patient had a change in his voice tone; Beard and armpit hair grew out; The patient had a good mood with sexual drive; luteotropic hormone, follicle-stimulating hormone and testosterone became normal. The patient's sperm density was 20×109/L, and the average sperm motility was higher than 30%. ConclusionPulse pump GnRH conforms to the physiological rhythm of GnRH secretion with a good clinical efficacy and tolerance. So we recommend GnRH pump as the preferential choice for treatment of hypogonadotropic hypogonadism.
ObjectiveTo discuss the clinical characteristics, treatment and prevention of abdominal wall endometriosis (AWE). MethodsA retrospective analysis of 295 cases of AWE from February 2007 to August 2011 in our hospital was performed. ResultsAll of the patients had abdominal operations before and 99% of them had a history of caesarean section. The mean age of the patients was (31.55±4.52) years old. The average size of the mass was (2.66±1.12) cm, significantly larger than the estimation of ultrasonography before operation which was (1.91±0.83) cm (P<0.001). No relapse was discovered five months to three years after the operation. ConclusionIt is easy to diagnose abdominal wall endometriosis through medical history, clinical characteristics, physical signs and ultrasonic assessment. The prevention of AWE is very important. Operation is still the best treatment for AWE.
【Abstract】Objective To investigate the role of early surgical intervention in the treatment of fulminant acute pancreatitis (FAP).Methods Eight cases of FAP admitted to our institution from September 2003 to December 2004 were reviewed retrospectively.Results Averagely 3 organs dysfunction was diagnosed on admission or in the course of treatment in this group. One patient treated non-operatively was dead. Of 7 cases with early surgical intervention, one was died of ACS and ARF, One female patient with 32 weeks pregnancy survived, but the fetus was dead before surgery. Five cases were complicated with intra-abscess, which were cured re-operatively. Conclusion Early operative intervention in the treatment of FAP could prevent MODS and improve the survival.
Since November 1974 to December 1993, 110 cases with malignant tumors of the extremities were treated by en bloc resection and limb salvage procedure in our hopsital. There were 57 males and 53 females. Their ages ranged from 14 to 70 years. The diagnosis of all patients were confirmed by pathology. Among them, 68 cases were malignant bone tumor, 42 cases were malignant tumor of soft tissue. If the soft tissue was involved by the malignant tumors, the tumor was resected radically and myocutaneous or skin flap was transferred to covered the defect. Among the 42 cases, 5 were free vascularized and 37 were pediculated flaps. The maximal size of the flap was 15×25 cm and the minimal was 6×8 cm. For the malignant bone tumors, en bloc resection was performed and the bone defect was reconstructed with autogenous free vascularized fibular graft, autograft of massive bone with fusion or allograft of cryogenic massive bone. If the joint was involved, limited excision with replacement of prosthesis was recommended. When both soft tissue and bone were involved, segmental resection of tumor was indicated in 17 cases. The patients were followed up for 2 to 9 years, the results of 53 cases were still alive with a survival rate of 48.2%. We emphasized that the local extensive resection should be performed with a safety margin of 3 to 5 cm beyond the tumor. A djuvant chemotheapy and radiotherapy had definite value in the treatment of some malignant tumors, so that preoperative or postoperative chemotherapy or radiotherapy was necessary. Sometimes radical resection of regional lymph rodes was necessary. The indications and causes of recurrence were discussed.
