Objective To study the occurrence mechanism and the clinical practice feasibility of cases of cavum tympani natural shaping after partial radical mastoidectomy. Methods A total of 18 radical mastoidectomy cases between June, 1996 and June, 2006 were analyzed, and the relationship between pathological characteristics, operation-performing features as well as dressing change after the operation and the phenomenon of tympanic membrane regeneration and healing were studied. Results In 21 out of 46 cases, tympanic membrane was regenerated and healed after the operation, among which hearing recovered completely in 2 cases, noticeably improved in 6 cases, partly improved in 11 cases and not improved at all in 2 cases. Conclusion Attention paid to the protection of remnant tympanic membrane and middle ear biography tone structure in radical mastoidectomy, together with rational use of medication after the operation, can generally contribute to the natural regeneration and healing of the cavum tympani and obvious improvement of hearing.
ObjectiveTo investigate the relationship between hormone and liver regeneration.MethodsThe related literatures in recent years were collected and reviewed.ResultsHormone was related to liver regeneration significantly and participated the process of liver regeneration. It had a promotive or inhibitive role in liver regeneration.ConclusionHormone is one of the important factors in the regulation of liver regeneration.
Objective To detect the clinical manifestations, diagnos is and treatment of painful ophthalmoplegia syndrome. Methods The data of onset, clinical m anifestations, laboratory examination, imaging and treatment from 12 patients with painful ophthalmoplegia, hospitalized from Mar, 2000 to Aug. 2005, were retro spectively analyzed. Results Multiple characters and extents of the headache were found in these 12 patients. The involved cranial nerves included the Ⅲ,Ⅳ, V1-2 and Ⅵ, especially the cranial nerve Ⅲ(83.3%). Several simultaneously in volved cranial nerves were frequently found (75%). Diseases which could cause hea dache along with ophthalmoplegia must be excluded before the diagnosis of the painful ophthalmoplegia syndrome was established. The examination of imaging was important for the diagnosis of painful ophthalmoplegia syndrome. Patients were sensitively responsive to cortico-steoid therapy. The cure rate was 75%. Conclusion The features of clinical manifestations, imaging results and the patients response to cortico-steoid therapy accorded with the etiology of nonspecific inflammation granuloma. Cortico-steoid therapy is effective after the definitude of the disease. (Chin J Ocul Fundus Dis, 2006,22:385-386)
Through searching and evaluating the evidence on advanced prostate cancer, we found that different types of androgen deprivation had similar effect, and immediate androgen deprivation had survival benefit. For the patient with hormone-refractory prostate cancer, therapies including mitoxantrone, prednisone, docetaxel and surmine were more effective. Strontium-89 provided more effective pain relief than external beam radiation. And bisphophonate had no effect. Antiandrogen withdrawal suggested prostate specific antigen would decline, but the clinical outcome wasn’t reported.
Objective To compare the efficacy and safety of different cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) combined with endocrine therapy (ET) for the treatment of hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2−) advanced or metastatic breast cancer. Methods Randomized controlled trials (RCTs) on CDK4/6i for the treatment of HR+/HER2− metastatic or advanced breast cancer were retrieved from databases including PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, Wanfang, VIP, and SinoMed, with the search period ranging from database inception to August 2023. Bayesian network meta-analysis was conducted using R 4.2.0 software. Results A total of 18 RCTs from 25 articles, involving 8 031 patients and 11 treatment regimens, were included. There was no significant difference in progression-free survival (PFS) or overall survival (OS) among different CDK4/6i+ET combinations. The highest cumulative probability for PFS was observed with dalpiciclib (DAL)+fulvestrant (FUL), while ribociclib (RIB)+FUL ranked first for OS. In terms of efficacy, abemaciclib (ABE)+aromatase inhibitors (AI) and ABE+FUL ranked first in objective response rate and clinical benefit rate, respectively. Regarding safety, statistically significant difference in grade 3-4 adverse events was observed among certain types of CDK4/6i (P<0.05). Conclusion Current evidence suggests that CDK4/6i+ET is superior to ET alone for the treatment of HR+/HER2− advanced/metastatic breast cancer. Different CDK4/6i+ET combinations demonstrate comparable or similar efficacy; however, the incidence of adverse reactions is higher with combination therapy. Treatment regimens should be selected based on individual conditions.
Objective To investigate the delay of the denervated skeletal muscle atrophy with the method of restraining the increment of the connective tissues by tetrandrine and hormone. Methods The left hind limbs of 42 male adult SD rats were made into models of the denervated gastrocnemius, and then the rats were randomly divided into 3 groups, with 14 rats in each. In Group A, tetrandrine (8 mg/L）was injected into the denervated gastrocnemius; in Group B, triamcinolone acetonide（1.6 g/L） was injected; in Group C (the control group),normal saline was injected. Enough samples were obtained according to the different observation indexes at 30 days after operation. Electromyography, muscle wet weight measurement, light microscopy,electron microscopy,and microimage analysis were performed. ResultsThe fibrillation potential amplitude was 0.195 8±0.041 9 μV in Group A and 0.185 2±0.050 3 μV in Group B, and there was no significant difference betweenthe two groups (Pgt;0.05). However,in Group C the fibrillation potential amplitude was 0.137 7±0.058 9μV. The fibrillation potential amplitude was significantly greater in Group A than in Group C（Plt;0.05）. The muscle wet weight was 1.740 0±0.415 9 g in Group A and 1.940 1±0.389 4 gin Group B, and there was no significant difference between the two groups(Pgt;0.05).However, in Group C the muscle wet weight was 0.800 0±0.100 0 g. The muscle wet weight was significantly greater in Group A than in Group C（Plt;0.05）.The microscopy showed that more remarkable atrophy occurred in the control group. The muscle fibers were more complete, thicker and larger, with more nuclei and clearer cross-lines. More connective tissue and flat cells could be observed in Groups A and B. The myogenic protein amount was 440.124 2±46.135 6 in Group A and 476.211 4±41.668 8in Group B, and there was no significant difference between the two groups(Pgt;0.05).However, in Group C the amount was 380.040 0±86.315 9.The myogenic protein amount was significantly greater in Group A thanin Group C（Plt;0.05）. The muscle fiber number, diameter, cross section, and connective tissue increment were all significantly greater in Group A than in Group C（Plt;0.05）; however, there wasno significant difference between Groups A and B (Pgt;0.05). The electron microscopy showed that there were more degeneration changes, such as muscle silk disorder, chondriosome disappearance, and hepatin reduction, could be observed inGroup C than in Groups A and B. Conclusion Tetrandrine and hormone can delay the denervated skeletal muscle atrophy by restraining the increment of the connective tissues.
Objective To systematically evaluate the effectiveness of platelet increasing capsule combined with hormone in treating idiopathic thrombocytopenic purpura (ITP). Methods Randomized controlled trials (RCTs) of ITP treated by platelet increasing capsule combined with hormone were electronically searched from PubMed (1966 to 2012), The Cochrane Library (CENTRAL, Issue 3, 2012), CBM (1978 to 2012), CNKI (1979 to 2012), WanFang Data (1998 to 2012), and VIP (1991 to 2012). References of included studies were also retrieved. The literature was independently screened according to exclusion and inclusion criteria by two researchers independently and meta-analysis was conducted using RevMan 5.1 software after data extraction and quality assessment. Results 10 RCTs were included involving 588 patients. The results meta-analysis showed that, the group which was treated by platelet increasing capsule combined with hormone was superior to the hormone alone group in the aspects of overall effectiveness rate (RR=1.18, 95%CI 1.06 to 1.32, P=0.003), the significant effectiveness rate (RR=1.57, 95%CI 1.29 to 1.91, Plt;0.000 01), blood platelet count (MD=21.54, 95%CI 13.85 to 29.23, Plt;0.000 01), and the recurrence rate (RR=0.49, 95%CI 0.34 to 0.69, Plt;0.000 01) which was lower. Conclusion Current evidence has showed that platelet increasing capsule combined with hormone in treating ITP is better than hormone alone. However, more high quality RCTs are needed to verify the above conclusion in future.
Breast cancer is one of the most common malignant tumors in women. The systematic therapy of breast cancer may affect the endometrium and ovarian function, such as abnormal endometrial hyperplasia and abnormal uterine bleeding caused by ovulation disorders. If we do not consider the patients suffering from breast cancer, we can use progesterone drugs to stop bleeding, regulate menstruation, and protect the endometrium. But there is no consistent conclusion on the safety of progesterone drugs in breast cancer patients. This article reviews the security of progesterone drugs in breast cancer survivors from the perspective of basic and clinical research. At present, whether the use of progesterone drugs in breast cancer survivors increases the risk of disease may be related to the type, dosage, and method of use of progesterone drugs. At the same time, it is also related to the type of breast cancer the patient has. Based on the available data, it is safe to use natural progesterone or dydrogesterone for the short term in patients with breast cancer. More studies are needed to evaluate other approaches.
ObjectiveTo investigate the effect of high-dose hormone pulse therapy on children with epilepsy and sleep status epilepticus.Methods60 children were randomly divided into control group (30 cases) and study group (30 cases) according to the admission sequence. The control group was treated with antiepileptic drugs (according to clinical electroencephalogram or syndrome), and the study group was treated with methylprednisolone sodium succinate [20 mg/(kg·d) × 3 days, once a month, for 6 months]. During the period, antiepileptic drugs were taken normally. After 6 months, the curative effect, abnormal EEG and side effects were compared.ResultsAfter 6 months of treatment, the clinical conditions of the two groups were significantly improved (effective rate: control group: 19/30 vs. study group: 26/30), and the clinical efficacy (26/30) and EEG improvement (26/30) of the study group were better than those of the control group (P<0.05), weight gain can be improved by diet control and reasonable exercise.ConclusionHormone pulse therapy for children with epilepsy and sleep status epilepticus in the control of clinical seizures and improve the effect of abnormal EEG, recommended.
Objective To explore the hormone medication compliance in children with chronic kidney disease (CKD) and analyze its influencing factors. Methods Between May and December 2013, 96 children were investigated by questionnaires about medication compliance when they were out of the hospital. Then we analyzed the influencing factors for medication compliance. All the data were analyzed by SPSS 19.0 software. Results Of these 96 children, medication nonadherence accounted for 52% (50). The main guardian, educational level of the father, educational level of the mother, residence, duration of illness, time of hospitalization, and understanding of the treatment plan played significant roles in causing different medication compliance among these children (P＜0.05). Logistic regression analysis showed that duration of illness [OR=2.204, 95%CI (1.253, 3.875), P=0.006], residence [OR=2.615, 95%CI (1.0 23, 6.687), P=0.045] and the mother’s educational level [OR=0.147, 95%CI (0.028, 0.788), P=0.025] were the independent factors for medication compliance. Conclusions According to the survey, hormone medication compliance in children with chronic kidney disease is not satisfying. We should strengthen the health education in children and their parents, and adopt specific interventions to enhance the medication compliance so as to effectively control the disease and delay the progression.
