成神经细胞瘤骨转移的X线诊断(附13例报告)

目的探讨成神经细胞瘤骨转移的X线表现及分型。方法分析13例成神经细胞瘤骨转移的X线表现，并根据X线表现将其分为溶骨型和成骨型。结果13例患者中，溶骨型9例，成骨型4例，各型病例均有其特征性的X线表现。结论根据患者年龄及特征性的X线表现，对成神经细胞瘤骨转移可作出诊断。     

医学基础课程模块式教学初探

医学基础知识教育存在学习内容衔接的矛盾及相互重叠、理论脱离实际、基础脱离临床、教师教法单一、学生学法被动等弊端。只有整合医学基础知识,进行模块式教学,才能在有限的学时内,使学生掌握医学基础知识,为其后续临床课学习及今后的职业生涯打好基础。     

醋酸棉酚对大鼠肾皮质形态结构的影响

醋酸棉酚每天30mg/kg(6次/周)给药6～8周后,大鼠肾曲小管线粒体肿胀,嵴模糊,伴有早期溶酶体增多、增大,形态多样,其后转而减少、变小。肾近曲小管微绒毛水肿,部分肾曲小管基底膜水肿。未见肾小球毛细血管内皮细胞、基膜和足细胞的超微结构明显变化。     

老年腰椎间盘突出症的手术治疗

目的 探讨老年腰椎间盘突出症的特点与手术治疗效果.方法 对62例老人腰椎间盘突出症患者的临床与病理特点进行分析.均行腰椎后路椎板减压髓核摘除术,其中小切口开窗35例,半椎板切除20例,全椎板切除7例,根据手术前后JOA评分评价手术疗效.结果 老年腰椎间盘突出症病理以髓核组织的脱水,纤维环的破裂,小关节囊、周围韧带及软骨终板退变为主要特点.临床特点为下肢疼痛多发,腰部活动受限较多;双下肢神经系统检查肌力下降明显,生理反射改变明显.62例平均随访1.9年,JOA评分术后平均改善率为68.9%,手术前后JOA评分比较差异有显著性意义(P＜0.05).结论 老年腰椎间盘突出症患者病程长,体征多,病理改变明显,行腰椎后路椎板减压髓核摘除术,手术效果满意.     

Early ocular hypertension after cataract extraction

The intraocular pressure (IOP) course during the first postoperative month was measured with Goldmann applanation tonometry in 93 eyes. The patients include 30 eyes of intracapsular cataract extraction (ICCE), 32 eyes of extracapsular cataract extraction (ECCE) and 31 eyes of ECCE combined with posterior chamber intraocular lens (PC-IOL) implantation. The preoperative average IOP was 13.30 +/- 3.24 mmHg in 93 eyes. The first day after cataract extraction was 25.33 +/- 8.18 mmHg and 59 eyes (63.44%) had an IOP higher than 23 mmHg. On the second day it was 16.03 +/- 7.54 mmHg. On the third day it was 14.69 +/- 5.45 mmHg. On the seventh day it was 13.32 +/- 3.44 mmHg and only 2 eyes (2.14%) IOP was higher than 23 mmHg. The first postoperative month average IOP was 12.93 +/- 1.31 mmHg and it was above 23 mmHg in only one eye. When compared with preoperation a significant increase in IOP was found postoperatively. But on the seventh day and after the first month there was no significant difference (P greater than 0.05). The IOP rise among ICCE group, ECCE group and PC-IOL group did not differ significantly.     

肝内HBcAg与血清学指标的关系及慢性乙型肝炎发病机理的探讨

We detected the presence and distribution of HBcAg in the liver by immunohistochemistry (ABC method) and the presence of HBV-DNA in serum (spot hybridization) and anti-HBe in serum (ELISA) from 59 cases of hepatitis B hospitalized in our hospital, including 47 cases of CAH, 5 cases of CPH, and 7 cases of subacute fulminant hepatitis. 1. HBcAg in the liver was detected in 25 out of 47 cases (53%) of CAH, in 2 out of 5 cases of CPH and in 4 out of 7 cases of subacute fulminant hepatitis. The total percentage was 53% (31/59). 2. There was no positive correlation between HBV replication activity and liver disease activity (P greater than 0.05). Our results did not support the hypothesis that suggests a direct cytopathic effect of HBV. Oppositely, the fact was that the presence, the amount and the patterns of HBcAg in the liver, and the presence of HBV-DNA in serum were predominant in mild CAH compared with those in severe CAH, predominant in CAH without cirrhosis compared with those in CAH with cirrhosis. There was a tendency of inverse correlation between HBV replication activity and liver disease activity. The results above were in line with the concept that HBcAg expressed on the surface of infected hepatocytes may be relevant target for T lymphocyte cytotoxicity. The results have suggested that an immune response to HBV is present, leading to the destruction of most infected cells. 3. There was a positive correlation between HBV-DNA in serum and HBcAg in the liver (P less than 0.005), indicating that HBV-DNA in serum can represent HBV replication.(ABSTRACT TRUNCATED AT 250 WORDS)     

ENDOURETHRAL URETHROPLASTY WITH PREPUCE GRAFT FOR LONG POSTERIOR URETHRAL STRICTURE

Twenty patients underwent endourethral urethroplasty with free prepuce graft in combination with transurethral resection of scar for posterior urethral stricture. Two-year follow-up showed that they had good continent and free voiding results. Problems about surgical technique were detailed. We conclude that a free full-thickness prepuce evenly patched by means of the tube balloon to the freshly prepared wound derived from the stricture is the key to surgical success.
