至阳八阵穴隔附子饼灸治疗糖尿病胃轻瘫临床研究

目的观察至阳八阵穴隔附子饼灸治疗脾胃气虚型糖尿病胃轻瘫的疗效及对胃泌素(GAS)、胃动素(MTL)和血管活性肠肽(VIP)水平的影响。方法86例脾胃气虚型糖尿病胃轻瘫患者随机分为对照组和治疗组,每组43例。治疗组给予至阳八阵穴隔附子饼灸;对照组口服枸橼酸莫沙必利片。治疗12周后观察胃轻瘫主要症状指数量表症状积分改善情况、胃排空率及血清GAS、MTL、VIP水平。结果治疗组治疗后在胃轻瘫主要症状指数量表症状积分及胃排空率方面明显高于对照组,差异均有统计学意义(P<0.05)。治疗组治疗后血清GAS、MTL水平明显高于对照组,血清VIP水平明显低于对照组,差异均有统计学意义(P<0.05)。治疗组总有效率为90.7%,明显高于对照组的72.1%(P<0.05)。结论采用至阳八阵穴隔附子饼灸能快速促进糖尿病胃轻瘫患者胃功能的恢复,改善症状和体征,其作用机制可能与升高患者血清GAS和MTL水平,降低VIP水平有关。     

The Effect of Treatment Sequence on Overall Survival for Men With Metastatic Castration-resistant Prostate Cancer: A Multicenter Retrospective Study

IntroductionWe aimed to evaluate the treatment sequence for patients with metastatic castration-resistant prostate cancer (mCRPC) in real-world practice and compare overall survival in each sequential therapy.Patients and MethodsWe retrospectively evaluated 146 patients with mCRPC who were initially treated with androgen deprivation therapy as metastatic hormone-naive prostate cancer in 14 hospitals between January 2010 and March 2019. The agents for the sequential therapy included new androgen receptor-targeted agents (ART: abiraterone acetate or enzalutamide), docetaxel, and/or cabazitaxel. We evaluated the treatment sequence for mCRPC and the effect of sequence patterns on overall survival.ResultsThe median age was 71 years. A total of 35 patients received ART-ART, 33 received ART-docetaxel, 68 received docetaxel-ART, and 10 received docetaxel-cabazitaxel sequences. The most prescribed treatment sequence was docetaxel-ART (47%), followed by ART-ART (24%). Overall survival calculated from the initial diagnosis reached 83, 57, 79, and 37 months in the ART-ART, ART-docetaxel, docetaxel-ART, and docetaxel-cabazitaxel, respectively. Multivariate Cox regression analyses showed no significant difference in overall survival between the first-line ART (n = 68) and first-line docetaxel (n = 78) therapies (hazard ratio [HR], 0.84; P = .530), between the ART-ART (n = 35) and docetaxel-mixed (n = 111) sequences (HR, 0.82; P = .650), and between the first-line abiraterone (n = 32) and first-line enzalutamide (n = 36) sequences (HR, 1.58; P = .384).ConclusionThe most prescribed treatment sequence was docetaxel followed by ART. No significant difference was observed in overall survival among the treatment sequences in real-world practice.     

Z形皮瓣及推进皮瓣修复眼睑缺损的作用探讨

目的探讨眼睑恶性肿瘤切除术中应用Z形皮瓣及推进皮瓣I期修复眼睑缺损的临床效果。方法将50例眼睑恶性肿瘤切除术患者按不同缝合方法分为两组,即对照组25例,术中直接缝合;观察组25例,术中行Z形皮瓣及推进皮瓣I期修复;比较两组眼睑修复效果。结果观察组术后皮瓣成活率96.0%、切口Ⅰ期愈合率100%、修复满意率92.0%,均高于对照组的72.0%、68.0%、56.0%,差异有统计学意义(P<0.05)。观察组术后并发症发生率低于对照组,但差异无统计学意义(P>0.05)。结论眼睑恶性肿瘤切除术中眼睑缺损修复时,采用Z形皮瓣及推进皮瓣,眼睑修复良好,患者修复满意率高,值得推广应用。

铜绿假单胞菌噬菌体PaP3生物学特性的研究

目的测定铜绿假单胞菌噬菌体PaP3的最佳感染复数、一步生长曲线和吸附K值及交叉吸附K值等基本生物学特性。方法按照感染复数（MOI）分别为0．0001、0．001、0．01、0．1、1和10加入噬菌体纯培养液和宿主菌，充分裂解细菌后，测定噬菌体滴度；以MOI=10的比例加入噬菌体及宿主菌，进行一步生长实验；纯化PaP3颗粒，免疫家兔，获得抗血清，通过中和反应实验测定PaP3和其抗血清之间的吸附反应常数K值。同时，利用抗血清交叉中和试验确定本室分离的三株噬菌体之间的血清学关系。结果当MOI=0．001时PaP3感染其宿主菌产生的子代噬菌体滴度最高；根据一步生长实验结果绘制一步生长曲线；通过血清交叉中和反应得出不同的吸附常数。结论PaP3最佳感染复数为0．001，感染宿主菌的潜伏期是20min，爆发期是60min，平均爆发量约为31，其抗血清反应的吸附常数K值为262。

A profile of invasive cutaneous malignant melanoma in Malta: 1993–2002

BACKGROUND: The incidence of malignant melanoma of the skin has risen in every part of the world where reliable cancer registration data are found. OBJECTIVE: Our study aims to describe the changing incidence of and survival from invasive cutaneous malignant melanoma in Malta, by analysing the data from the 211 cases that were registered at the Malta National Cancer Registry between 1993 and 2002. RESULTS: The age standardized incidence rates for invasive cutaneous malignant melanoma rose from 3.7 per 100,000 population per year for males and 5.1 for females in the first 5-year period, to 8.0 per 100,000 population per year for males and 5.9 for females in the second 5-year period. In both sexes, numbers of thin (< or = 1.0 mm) invasive melanomas increased significantly between 1993 and 2002; males also registered a significant increase in intermediate-thickness (1.01-4.0 mm) melanomas. The increase in numbers of thin and intermediate-thickness melanomas between the two 5-year periods was greatest in patients aged 60 years and over. The overall absolute 5-year survival rate for the first period was 74% and for the second period 92%. CONCLUSION: Numbers of reported cases of invasive cutaneous malignant melanoma in Malta have more than doubled during the 10-year study period. This is mostly due to a marked rise in the diagnosis of thin melanomas in both sexes, occurring mainly in patients aged 60 years and over. As thin melanomas are of low metastasizing potential, this has resulted in an increase in survival between the two 5-year study periods.
