MRI manifestations of peritoneal carcinomatosis.

Three cases of proved peritoneal carcinomatosis were examined by magnetic resonance imaging (MRI). Air was used to distend the entire gastrointestinal tract via an antegrade method. The findings included seedings along the small intestine, transverse and sigmoid colon, stellate pattern in the mesentery, plaque-like and bulky tumor masses in the mesentery and greater omentum, and focal thickenings along the right subdiaphragmatic parietal peritoneum. Stenosis caused by tumor encasement at the duodenojejunal junction and ileocolic anastomosis were first detected by MRI and later confirmed by barium studies. Ascites was present in all cases. One case showed ascites located only along the left paracolic gutter. This report shows that MRI is also able to demonstrate peritoneal carcinomatosis by using air as a gastrointestinal contrast medium.     

小儿氨基酸注射液治疗胎儿宫内发育迟缓的探讨

经临床鉴定静脉内注射小儿氨基酸对治疗胎儿宫内发育迟缓具有肯定效果。在Ｂ超监视下，使用小儿氨基酸的孕妇组于用药期间，胎儿生长参数ＢＰＤ和ＨＣ显著高于使用成人氨基酸的孕妇组。１０例足月娩出胎儿体重均达到甚至超过２．５ｋｇ。由此得出结论：使用小儿氨基酸注射液对于改善胎儿宫内发育迟缓优于成人氨基酸。     

Clinical observation of Qi deficiency syndrome in 72 patients with chronic obstructive pulmonary disease treated with Yiqi Mianyi Granule

Seventy-two patients of chronic obstructive pulmonary disease (COPD) of Qi deficiency syndrome with abnormal immune indices were treated with Yiqi Mianyi Granule (YQMYG) and the efficacy was compared with that of 30 cases treated with Zhenqi fuzheng Granule (ZQFZG) for control. Results showed that the markedly effective rate of symptomatic improvement of Qi deficiency in YQMYG group was 65.3%, the total effective rate 93.1%. 88.6% of the immune indices lower than normal were corrected and 43. 7% of them were normalized, while for indices that were higher than normal the rate were 78.2% and 52.9% respectively. These results suggested that YQMYG could improve symptom of Qi Deficiency markedly, strengthen cellular immunity and regulate immune dysfunction. Its therapeutic efficacy was obviously superior to ZQFZG (P<0.Q5).     

Principles for managing penetrating craniocerebral injuries caused by firearm missiles

Penetrating craniocerebral firearm injuries remain one of the most lethal causes of all trauma and are common both in war or peace time. Data were reviewed for 4140 severely head-injured patients (Glasgow Coma Scale (GCS) scores 3-8) treated at Xi-Jing Hospital between 1973 and 1993; 51 of these patients had acute penetrating craniocerebral injuries caused by firearm missiles. These patients consisted of 46 males (90.2%) and 5 females (9.8%) ranging in age from 3 months to 48 years (median 22.4 years). The lesion types included 2 tangential wounds, 37 tubular wounds and 12 through-and-through wounds. All cases were urgent with the patients in severe and unstable states. After emergency treatment and operation, 5 cases died (9.8%). Follow up studies at three months showed that 23 cases (45.1%) had made a good recovery. Moderate disability, severe disability and vegetative states in this series were 29.4%, 13.7% and 2.0% respectively. Long term follow up studies indicated that 32 were able to resume their occupation. The principles for managing penetrating craniocerebral firearm injuries and suggestions for operation are discussed.     

微小病变型肾病综合征患者IL－2的检测及其意义

３２例微小病变型肾病综合征（ＭＣＮＳ）患者，采用￣３Ｈ－ＴｄＲ掺入法测定其外周血Ｔ淋巴细胞产生白介素２（ＩＬ＿２）的浓度，结果显示本病患者Ｔ细胞产生ＩＬ＿２的能力显著降低，与对照组相比差异非常显著（Ｐ＜０．０１），故认为ＭＣＮＳ的发生与Ｔ细胞功能异常有关。     

A clinico-pathological study of resected lung cancer cases accompanied by pleural dissemination

A total of 26 lung cancer cases accompanied by pleural dissemination were resected between June 1977 and June 1988. Of these 16 cases were male and 10 cases were female. Their age was 34-78, and the average age was 56.7 years. The histologic type was adenocarcinoma in 23 cases, 1 was large cell carcinoma, 1 was combined adenosquamous cell carcinoma, and 1 was combined adeno-small cell carcinoma. Of these 23 adenocarcinoma cases, 15 were well differentiated, 7 were moderately differentiated, and 1 was poorly differentiated. There was no correlation between tumor size and pleural dissemination. Pleural effusion was observed in 8, 5 had bloody effusion and the other 3 had yellow effusion. Exact preoperative diagnosis and evaluation of extent was very difficult in pleural dissemination cases except for the pleural effusion cases. Concerning the operation method in these cases pleuropneumonectomy was performed in 10, pleurolobectomy in 6, and lobectomy in 10. Prognosis of cases of resected pleural dissemination was very poor. The median survival time was 16 months, The 1-year survival rate was 56.3%, the 2-year survival rate was 23.2%, the 3-year survival rate was 15.4%, and the 4-year survival rate was 7.7%. There was no 5-year survivor in lung cancer cases of this group. Malignant pleural effusion cases had a poorer prognosis, with 6 of 8 cases dying within 1 year from operation. No remarkable therapeutic effects were achieved by adjuvant chemotherapy. In the single case of preoperative hyperthermia, histological therapeutic effect (Ef 2) was recognized. These results suggest that there is no indication of operation in malignant pleural effusion cases.(ABSTRACT TRUNCATED AT 250 WORDS)     

Neurofibromatosis type 1: brain stem tumours

We describe the clinical and imaging findings of brain stem tumours in patients with neurofibromatosis type 1 (NF1). The NF1 patients imaged between January 1984 and January 1996 were reviewed and 25 patients were identified with a brain stem tumour. Clinical, radiographical and pathological results were obtained by review of records and images. Brain stem tumour identification occurred much later than the clinical diagnosis of NF1. Medullary enlargement was most frequent (68 %), followed by pontine (52 %) and midbrain enlargement (44 %). Patients were further subdivided into those with diffuse (12 patients) and those with focal (13 patients) tumours. Treatment for hydrocephalus was required in 67 % of the first group and only 15 % of the second group. Surgery was performed in four patients and revealed fibrillary astrocytomas, one of which progressed to an anaplastic astrocytoma. In 40 % of patients both brain stem and optic pathway tumours were present. The biological behaviour of brain stem tumours in NF1 is unknown. Diffuse tumours in the patients with NF1 appear to have a much more favourable prognosis than patients with similar tumours without neurofibromatosis type 1.

药物浓度和病因对三磷酸腺苷治疗阵发性室上性心动过速的影响

本文报告23例次ATP治疗PSVT的效果,总有效率56.5％,9例次高浓度快速注射者8例转复。器质性心脏病者副作用较多,1例冠心速注高浓度ATP后,发生心室颤动和阿-斯氏综合征。这一结果提示:药物浓度和注射速度是影响疗效的主要因素,PSVT伴AVB者疗效也很低;病因和药物浓度是决定副作用的因素。因此,对于器质性心脏病者,尤其冠心病人,应避免高浓度快速静脉注射ATP。     

The role of oxygen free radicals in craniocerebral injury

Serum LPO content was measured by means of TBA in 41 patients suffering from craniocerebral injury in present study. The relationships between OFR and progressing course of craniocerebral injury, level of LPO and patient condition of an injury and prognosis were analysed. Results showed that serum LPO increased obviously in 24 hours after injury. The more severe the condition of an injury was, the higher the serum LPO content was, the worse prognosis would be. Serum LPO content increased statistically in group of death in 24 to 72 hours after injury, while it didn't change significantly in group of survival. The author suggest that the reaction of OFR enhanced after craniocerebral injury, and which was an important factor giving rise to secondary brain injury. Measurement of serum LPO content plays an important role in estimating the patients condition of injury and their prognosis.
