Emergency free flaps to the type IIIC tibial fracture

Type IIIC tibial fractures are complex injuries involving extensive bone and soft-tissue devascularization that result in a high percentage of complications and ultimate amputation. An emergency free flap transfer not only may salvage the limb but also may improve the aesthetic and functional results of reconstruction by placing the injured structures in a well-vascularized bed. Two cases of type IIIC tibial fracture were treated in this manner, and we present our experience with a 30-month follow-up of one patient and a 6-month follow-up of another patient.

继发性肝癌的联合治疗

采用手术切除联合术后B超引导肝内门静脉区域化疗（简称PHPC）治疗胃肠道癌异时肝转移24例。随访4～54个月，结果：术后经3个疗程的PHPC，8例已存活肥18～48个月；13例分别经过2～11次的PHPC，已存活5～39p个月；另3例死亡。作者认为，对继发性肝癌采用手术切除配合术后B超引导的PHPC是一种延长患者生存期的有效联合治疗方案。     

57例小儿肺炎患者T淋巴细胞亚群及NK细胞观察

为了检测肺炎患儿的免疫功能,用 APAAP 法对57例反复患支气管肺炎的患儿进行 T 淋巴细胞亚群及 NK 细胞检测,结果 CD_3~+53.20±7.64%(对照组:62.50±9.65%),CD_4~+34.2±4.36%(对照组:38.64±4.05%),CD_8~+32.50±6.39%(对照组:26.70±4.23%)。CD_4~+/CD_8~+比值1.05±0.14(对照组:1.45±0.11),NK 细胞8.30±2.40%(对照组:6.44±3.37%)。结果证明,患儿 T 细胞亚群与对照组比较差异有显著(P<0.01),NK 细胞差异无显著性(P>0.05)。     

Heat probe thermocoagulation as a substitute for surgical intervention to arrest massive peptic ulcer hemorrhage: an experience in 153 cases

In a period of 2 years 7 months, we performed heat probe (HP) thermocoagulation in 153 cases of massive peptic ulcer hemorrhage. The male/female sex ratio was 125/28. The average age was 57.6 +/- 1.3 years (mean +/- SEM; range, 17 to 88). There were 69 cases (45.1%) of spurting hemorrhage, 50 cases (32.7%) of oozing hemorrhage, and 34 cases (22.2%) of nonbleeding visible vessels. Seventy-seven patients (50.3%) were in shock before therapy. After therapy we obtained initial success in 147 cases (96.1%). Rebleeding episodes occurred in 23 patients (15.6%) within 1 month after therapy. Nineteen patients received a second therapy, and treatment in 15 of these cases (78.9%) was ultimately successful. Finally, treatment in 142 cases (92.8%) was ultimately successful. The duration of hospitalization was 6.3 +/- 0.4 days (mean +/- SEM). After discharge all patients were followed at the outpatient department for at least 1 month. Sixty-seven patients were followed endoscopically for at least 2 to 3 months after therapy. Fifty-six patients (83.6%) had a healed scar at the previous bleeding site 2 months after therapy, and 62 patients (92.5%) had a healed scar 3 months after therapy. We conclude that HP thermocoagulation is an ideal and reliable modality of therapeutic endoscopy in arrest of massive peptic ulcer hemorrhage. HP thermocoagulation may become the first choice of therapy for massive peptic ulcer bleeding in the near future.     

老年人微小病变性肾病综合征的临床特征和长期随访

探讨老年人微小病变性(MC)特发性肾病综合征(PNS)的临床特征及预后。方法 观察成人MC性PNS118例,其中老年患者18例,占15.2％。结果 发现老年患者NS的临床表现与成年组相似;但血尿发病率较低,22％比38％;高血压和肾功能不全的发病率明显增高,38.9％比16％和33.3％比19％(P<0.01)。老年组对激素治疗的敏感性略差;但NS复发率明显减少,11.1％比43％。结论 尽管NS的复发和对激素依赖使治疗有一定困难,但激素、细胞毒性药物和环孢素A对于消除蛋白尿,延缓肾功能不全是有助的。     

腰椎峡部裂的CT诊断

4125例哈萨克族儿童斜视及弱视调查

本文对本地区五个县九所哈萨克族小学学生共计4125人进行了斜视、弱视的调查。调查对象全部为4—14岁哈萨克儿童。在受检儿童中发现斜视者48例,患病率为1.1％。外斜视32例占66.67％,内斜视16例占33.33％,斜视并有弱视者15例占31.25％。斜视而视力正常者33例占68.75％。在4125例受检儿童中发现弱视139例(209只眼),其患病率为3.37％,双眼弱视70例,单眼弱视69例,二者无显著差异。139例弱视中男性患者73例,女性患者66例,二者亦无差异。209例只弱视眼中轻度弱视84只眼占40.19％,中度弱视104只眼占49.76％,重度弱视21只眼共占10.05％。调查中笔者发现哈萨克族儿童弱视眼尤以屈光不正为多,209例眼中有106只为单纯性远视眼,因此笔者提出如何早期发现屈光不正并予以纠正将有可能防止许多弱视的发生。     

Anabolic and catabolic hormonal response of elite runners to training at high altitude

A 2-week training period 2000 meters above sea level performed by 6 male elite Swedish runners influenced neither basal anabolic (total and non-sex hormone-binding globulin (SHBG)-bound testosterone (NST) and insulin-like growth factor-1 (IGF-1) nor catabolic (cortisol) hormones when comparing serum levels prior to and after the training camp. The anabolic vs catabolic hormone balance, expressed as the NST: cortisol ratio, also remained unchanged as well as SHBG and body mass. Thus, training at 2000 meters above sea level, often practised by elite runners to improve performance in competition at sea level, does not result in a catabolic situation after return to sea level, as measured by peripheral hormones. However, the adaptation to high altitude was associated with a slight (NS) decrease in testosterone as well as in anabolic vs catabolic balance as measured the third day at high altitude. Simultaneously, a decrease in subjective performance was claimed by the runners, but could not be shown by objective measurements. From day 3 to day 9 at high altitude, all runners claimed a subjective recuperation of performance. Total and non-SHBG-bound testosterone increased significantly from day 3 at high altitude to the first post-camp sea-level test. The results reflect the necessity of adaptation when travelling to races at different altitudes. The Swedish runners had significantly higher cortisol, total testosterone and NST levels compared with basal values of a group of 17 elite Kenyan runners living and training at high altitude. Since the NST cortisol and IGF-1 values were not lower, a catabolic state or malnutrition was not likely to be present. The results might reflect an adaptation to altitude or ethnic variations.     

Conjunctival involvement of lymphomatoid granulomatosis

Lymphomatoid granulomatosis is an angiocentric and angiodestructive lympho-proliferative disorder involving multisystems but rarely conjunctiva. We present a 62-year-old Chinese female with lymphomatoid granulomatosis who had an ulcerative conjunctival nodule. Conjunctival biopsy revealed pathological findings important for diagnosis and indicating progression of disease severity. To our knowledge, this is the first report to demonstrate pathological findings characteristic of lymphomatoid granulomatosis with conjunctival involvement.
