Gaucher disease: abdominal MR imaging findings in 46 patients.

Abdominal magnetic resonance imaging findings were reviewed in 46 patients with Gaucher disease. All patients had hepatosplenomegaly at the time of initial imaging. Splenic nodules were present in 14 patients (30%) and varied in signal intensity. These nodules were isointense on T1-weighted and hypointense on T2-weighted images. Splenic infarcts were seen in 15 patients (33%), and four of these patients (9%) also had subcapsular fluid collections. Both nodules and infarcts were present in the spleen in four patients (9%). Pathologic correlation was performed with specimens from two patients who underwent partial splenectomy. Focal areas of abnormal signal intensity were noted in the liver in nine patients (20%). They were either stellate or segmental, and may represent fibrotic septa with ischemic changes associated with aggregates of Gaucher cells. No changes were noted in the kidneys or abdominal lymph nodes.     

Outcome study: comparison of short-term vs long-term treatment in a residential community.

All patients admitted to a Residential Treatment Center (RTC), a drug-free hospital-based inpatient facility in February 1985 through July 1985, were followed-up 6 months after discharge. The results are contrasted with those obtained in 1973 in a similar follow-up study. Length of stay at RTC had been reduced from 1 year in 1973 to 3 months in 1985. Six months after discharge, the longer length of stay in 1973 appears to be almost twice as effective as the 3-month program in 1985.     

Relationship among dosages of aminophylline, plasma levels of theophylline and variation of pulmonary arterial pressure]

The relationship among the dosages of aminophylline, plasma levels of theophylline and variations of mean pulmonary arterial pressure (mPAP) in 72 patients with COPD was investigated. The results showed that after a different loading dosage of aminophylline (6 mg/kg, 5 mg/kg and 4 mg/kg) was administered by intravenous injection, mPAP in the 6 mg/kg group was decreased more significantly (P less than 0.01) than that in the 4 mg/kg group. In the 6 mg/kg group, the decreased mPAP period sustained for 120 min, which was longer than that in the other 2 groups. The plasma levels of theophylline in the 6 mg/kg group of patients 30 to 120 min after loading dose injected were 115.54-79.04 mumol/L, which were higher than that in the others. Within the 120 min period of observation after the drug was administered no patients in any of these groups showed severe untoward effects. According to the results of this experiment, we suggest that the 6 mg/kg as a loading dose should be advised for the treatment of pulmonary hypertension in COPD. The optimum time to give the maintenance dosage should be set within 2 h after the loading dose. It is necessary to monitor the plasma levels of theophylline while aminophylline is administered, so that optimal therapeutic effects could be achieved without side effects.     

重度创伤患者外周血单个核细胞HLA-DR的表达与创伤后免疫功能障碍的关系

为了探讨创伤后机体细胞免疫、体液免疫及红细胞免疫功能障碍与外周血单个核细胞ＨＬＡ－ＤＲ表达率之间的关系，本文选择了３０例重度复合伤病人。在住院治疗期间，连续观察了患者受伤当日、伤后第３、１０、２０ｄ及出院前一天外周血单个核细胞ＨＬＡＤＲ表达率的变化及其与细胞免疫、体液免疫及红细胞免疫功能状况之间的相关性，发现创伤病人自受伤当日至出院前外周血单个核细胞膜上ＨＬＡ－ＤＲ表达率的变化无统计学意义（Ｐ＞０．０５），提示创伤后免疫功能障碍不是由于外周血单个核细胞ＨＬＡ－ＤＲ表达异常所致。

In this paper,250 cases of headache,shoulder pain,lumbago and leg pain weretreated with 20％Angelicae Sinensis mixed with Vitamine B_(12) point-injection therapy.The total effective rate was 95.2％and in which the cure rate was 53.6％.Authors have found a close correlation between the effectiveness and the duration of disease.     

Survival following hydrofluoric acid ingestion.

Systemic toxicity after significant dermal exposure to hydrofluoric acid includes rapid development of hypocalcemia and hyperkalemia, leading to ventricular fibrillation. Similar dysrhythmias have occurred in patients after ingestion of sodium fluoride-containing compounds. Ingestion of hydrofluoric acid could induce similar cardiac toxicity; however, reported cases of hydrofluoric acid ingestion rarely have been described, and the rapid death of these patients has not allowed verification of this hypothesis. On two separate occasions, a 70-year-old woman ingested up to 2 oz of a 8% hydrofluoric acid-containing solution. Recurrent ventricular fibrillation with concurrent hypocalcemia and hypomagnesemia complicated her first episode, whereas a more aggressive administration of calcium and magnesium may have prevented dysrhythmias in the second episode. Survival from ventricular fibrillation after hydrofluoric acid ingestion has not been reported previously and suggests a role for aggressive empiric calcium and magnesium replacement.

应用放射性配基结合分析法，检测了４０例结直肠癌及部分癌旁正常粘膜组织中的雄激素受体（ＡｎｄｒｏｇｅｎＲｅｃｅｐｔｏｒ，ＡＲ），同时分析了ＡＲ水平与临床病理学变化的关系。证实结直肠癌ＡＲ数目（３３．７±２３．３ｆｍｏｌ／ｍｇ蛋白）明显低于癌旁５ｃｍ以外粘膜（５３．９±３２．４ｆｍｏｌ／ｍｇ蛋白），Ｐ＜０．０１，而其亲和力则无变化；结直肠癌时ＡＲ数目变化与女性、直肠癌、高分化癌及早期癌关系密切。提示ＡＲ与结直肠癌关系密切，本实验为临床上结直肠癌的诊断及内分泌治疗提供了初步资料。     

The adverse effect of treatment prolongation in cervical cancer by high-dose-rate intracavitary brachytherapy.

BACKGROUND AND PURPOSE: The potential risk of prolongation of treatment time in cervical cancer has been reported for many low-dose rate (LDR) studies, with an estimated loss of local control ranging from 0.3 to 1.6% per day of treatment prolongation. Since the treatment schedule for fractionated high-dose rate intracavitary brachytherapy (HDRICB) is not directly comparable with that for low-dose rate studies, this report aims to evaluate the adverse effect of treatment prolongation specifically for cervical cancer treated with HDRICB. MATERIAL AND METHODS: From September 1992 to December 1997, 257 patients diagnosed with uterine cervical cancer (35 Ib, 26 IIa, 122 IIb, 10 IIIa, 57 IIIb, 7 IVa), who underwent external radiotherapy combined with between two and four courses of HDRICB and a minimum of 3 years of follow-up (median 57 months), were analyzed. Treatment consisted of irradiation of the whole pelvis with 44-45 Gy consisting of 22-25 fractions by 5 weeks, with the dose boosted to 54-58 Gy (with central shielding) for patients diagnosed as FIGO stage IIb-IVa bilateral parametrial disease. HDRICB was performed using an Ir-192 remote afterloading technique at 1-week intervals. The standard prescribed dose for each course of HDRICB was 7.2 Gy to point A for three insertions (before July 1995), or 6.0 Gy to point A for four insertions (after July 1995). Total prescribed point A doses (external beam radiotherapy+HDRICB) ranged from 58 to 71.6 Gy (median, 65.6 Gy) for stage IB-IIA, while analogous dosage for larger lesions (stage IIb-IVa) ranged from 59 to 75.6 Gy (median, 65.6 Gy). Kaplan-Meier and multivariate analyses were used to test the effect of treatment time on pelvic control rate (PCR) and cause-specific survival (CSS) at 5 years. RESULTS: Median treatment time was 63 days. For all stages of disease, the 5-year CSS and PCR were significantly different comparing treatment times of less than and greater than or equal to 63 days [83% and 65% (P=0.004], 93% and 83% (P=0.02), respectively]. These associations were also significant for stage Ib/IIa [97% and 79% (P=0.01), and 100% and 87% (P=0.02), respectively), but not for stage IIb [75% and 72% (P=0.79), and 93% and 87% (P=0.83), respectively] or stage III [66% and 49% (P=0.2), and 83% and 72% (P=0.21), respectively]. Multivariate analysis identified three prognostic factors for CSS, stage (P<0.001), tumor response to external RT (P=0.001), and overall treatment time (OTT; P=0.006). Prognostic factors for pelvic failure were stage (P<0.001), tumor response to external RT (P=0.001), and OTT (P=0.03). Prolongation of treatment time resulted in a daily decrease in pelvic control rate of 0.67% overall, and 0.43% for stage Ib-IIa, 0.57% for stage IIb, and 0.73% for stage III patients. CONCLUSION: Analysis of the data from the current study demonstrates that the adverse effect of treatment prolongation was observed later in the treatment course for the high-dose rate (HDR) series compared to the LDR analog, however, treatment-time prolongation still negatively influenced the cause-specific survival and pelvic control rate for both dosage groups.
