Effect of shenmai Injection on SIL-2R NK and LAK cells of patients with advanced carcinoma

Serum interleukin-2 receptor (sIL-2R) level, activities of natural killer cell (NK) and lymphokine activated killer (LAK) cells were determined in 60 patients with advanced carcinoma (AC) before and after treatment with Shenmai Injection (SMI), forty healthy persons were taken as non-carcinoma control (NC). The results showed that: Serum sIL-2R level in AC were much higher than those in NC (P<0.05) and activities of NK and LAK cells in AC were much lower than those in NC (P<0.05) before treatment. There was no significant difference among gastric, colonic and lung cancer (P>0.05). After treatment with SMI, it was found that the level of sIL-2R in all patients were obviously lowered (P<0.05) while the activities of NK and LAK cells were signifficantly higher than that prior the treatment (P<0.05). Relevancy was not found between sIL-2R and NK, LAK cells. These data suggested that the immune function was compromised in AC, and SMI has a wide effect of immuno-regulation.     

悬雍垂保留在悬雍垂腭咽成形术中的作用

目的 探讨悬雍垂保留在悬雍垂腭咽成形术(UPPP)中的作用。方法 比较43例UPPP与43例保留悬雍垂的改良UPPP的术中术后并发症、术后症状改善程度以及术后咽腔测量结果。结果 术中术后大出血、开放性鼻音、进流食返呛人鼻腔等并发症：改良UPPP明显低于UPPP(P＜0．05)；咽异物感：改良UPPP极明显低于UPPP(P＜0．01)。术后1年患者主观症状改善程度：明显改善者，改良UPPP高于UPPP，无改善者，UPPP高于改良UPPP，有显著性差异(P＜0.05)。术后1年咽腔扩大程度：下腭咽横径、前后径，改良UPPP较UPPP两者均明显扩大(P＜0.05)。结论 UPPP中保留悬雍垂可明显降低术中术后大出血、开放性鼻音、进流食返呛人鼻腔、咽异物感等并发症，术后症状明显改善，咽腔得到明显扩大。     

A study on various symptoms of chronic hepatitis treated with radix astragali and its regulative effect to levels of serum hormone

Sixty-seven cases of chronic hepatitis were treated with Radix Astragali. After treatment (2-month course), the clinical improvement rate in 38 cases of the Stagnation of the Liver-Qi and Deficiency of the Spleen type was 92.1%, and in 26 cases of the Deficiency of Liver Yin and Kidney Yin type was 88.5%, more effective than in the control group (P<0.05). The regulative effect to the levels of serum hormone was observed in the patients of the Stagnation of the Liver-Qi and Deficiency of the Spleen type treated with this medicine. The results showed that the levels of serum triiodothyronine, estradiol (female) and testosterone (male) were increased after treatment (1.40±1.38 ng/dl, 129.30±1.23 pg/ml and 496.24±1.47 ng/dl). Pre-treatment levels were 1.22±1.49 ng/dl, 104.60±1.45 pg/ml and 398. 17±1.55 ng/dl respectively (P<0.05); however, the level of serum prolactin (2.75±4.46 ng/ml) was lower after treatment than before treatment (3.20±3.82 ng/ml,P<0.05). No obvious changes were observed in the levels of serum follicle stimulating hormone, luteinizing hormone, thyroid stimulating hormone, thyroxine, triiodothyronine uptake ratio and cortisol after treatment.     

Fracture of the porous-coated metal tray of a biologically fixed knee prosthesis. Report of a case

It has been assumed that, when properly implanted, a biologically fixed device is less prone to loosening and probably to fatigue failure as well. This case demonstrates that many of the known risk factors of loosening or fatigue fracture of cemented tibial replacement devices must be considered when using devices designed for biologic fixation. Age, weight, axial alignment, and bone substrate have been identified as probable contributing factors to failure in the case reported here. Manufacturing technique and changes in material properties associated with porous coating should also be carefully tested for factors predisposing the components to fatigue failure.     

Rupture of the tendon of the long head of the biceps brachii. Surgical versus nonsurgical treatment

Twenty-seven shoulders (in 26 patients) that had surgical repair of a rupture of the long head of the biceps tendon between 1962 and 1981 were evaluated at three to 22 years after injury (mean, 13 years). Thirty similar patients had been treated nonsurgically and were evaluated two to 15 years (mean, 4.6 years) after tendon rupture. Biomechanical testing was performed on ten patients in the surgical group and 13 in the nonsurgical group. Residual arm pain was infrequent in both surgically and nonsurgically treated groups. Residual subjective weakness at the elbow was reported in four of the surgical group and in 20 of the nonsurgical group. Surgically treated patients returned to work later than nonsurgical patients; however, 11 in the nonsurgical group were not able to return to full work capacity, versus only two in the surgical group. On biomechanical testing, the nonsurgical group had lost a mean of 21% of supination strength and 8% of elbow flexion strength but had no weakness in grip, pronation, or elbow extension. The surgical group had lost no strength in any of these testing modes.

中国蒙,汉族酒依赖与醇脱氢酶和醛脱氢酶基因多态性的相关研究

为探讨醇脱氢酶（ＡＤＨ）基因和醛脱氢酶（ＡＬＤＨ）基因多态性与酒依赖患病的相互关系，用耳血干血痕聚合酶链反应、等位基因特异性寡核苷酸探针方法，检测乙醇代谢酶ＡＤＨ和ＡＬＤＨ基因型在我国蒙、汉民族酒依赖与非酒依赖者中分布频率。结果显示在酒依赖组（汉族５２例，蒙族３１例）与正常对照组（汉族４８例，蒙族３５例）之间：汉族的ＡＬＤＨ２基因型频率与等位基因频率的分布差异有非常显著性（Ｐ＜０．０１），而蒙族则表示为ＡＤＨ２基因型频率与等位基因频率的分布差异有非常显著性（Ｐ＜０．０１）。这提示汉族酒依赖的发病与ＡＬＤＨ２基因有关，蒙族则与ＡＤＨ２基因有关。
