Abstract
The concentrations of serum homovanillic acid (HVA), luteinizing liormone (LH), follicle-stimulating hormone (FSH) and testosterone (T) were examined in 20 male schizophrenic patients not taking neuroleptic drugs, 44 treated with neuroleptic drugs, and 15 male healthy control subjects. Kurskal-Wallis analysis of variance showed no significant difference among the three groups in serum HVA, FSH, LH or testosterone although high concentrations were found in tlte patients not taking neuroleptic drugs. There was a significant positive correlation between serum HVA and FSH in the patients not taking neuroleptics. The present results suggest that the change of gonadal hormones may be related to the pathogenesis of schizophrenia.

Abstract
Five patients who met the criteria of the persistent vegetative state (PVS), were studied for ten years. Among them, two had fallen into a deep coma after cardiopulmonary resuscitation, and the other three cases were due to cerebrovascular disorders. Four patients died within 10 years. Clinically, all five cases showed characteristic features of wakefulness without cognitive function and movement of the extremities. The brain stem reflexes, such as light reflexes of the pupils and corneal reflexes, were present. The electroencephalograms showed ample low amplitude and nonspecific slow waves. None revealed an isoelectric pattern. Brain stem auditory evoked potential (BAEP) studies were normal or slightly abnormal. Median nerve somatosensory evoked potential (SSEP) studies showed absence of a cortical response. These features suggest that the damage in PVS patients is mainly located in the cerebral cortex. Although electrophysiologic examinations are useful diagnostic procedures for PVS, clinical observation remains the basis of the diagnosis.

Abstract
Muscarinic receptor density increased by approximately 36% after differentiation induced by retinoic acid (Bmax, control = 126 +/- 13 fmol/mg protein; Bmax, retinoic acid-treated = 170 +/- 17 fmol/mg protein; P < 0.05), corresponding to a 170% increase in receptor content per cell. The affinity of [3H]NMS for the receptors was somewhat lower in the retinoic acid-treated cells (Kd, control = 0.14 +/- 0.04 nM; Kd, retinoic acid-treated = 0.25 +/- 0.04 nM; P < 0.05). Reverse transcriptase/polymerase chain reaction analysis using subtype-specific primers revealed that undifferentiated Sk-N-SH cells transcribed mRNA for all 5 receptor subtypes; this pattern was not affected by retinoic acid treatment. [3H]NMS displacement curves with subtype selective receptor ligands (pirenzepine, m1; AFDX-116, m2; 4-DAMP, m3) indicated the predominant expression of m3 and m1 receptor subtypes, and differentiation did not affect the pharmacological profile of the expressed receptor populations. The present results indicate that differentiation induces selective changes in the expression and activity of muscarinic receptors in a neuronal cell line.

Abstract
Moderate to severe functional tricuspid regurgitation was found in 26% of cardiac surgical patients with mitral or aortic valvular disease at Tri-Service General Hospital in Taiwan. Almost all patients were able to receive de Vega's annuloplasties. After a mean follow-up period of 20 months, none of the 63 patients had moderate or severe tricuspid regurgitation. There was no heart block or right atrial thrombosis; the single late death was not related to the heart disease. De Vega's tricuspid annuloplasty is considered to be a safe, effective, and durable procedure in the treatment of functional tricuspid regurgitation. Compared with tricuspid valve replacement and other types of annuloplasty, the de Vega is the first choice here.

Abstract
The serum noradrenaline (NA), homovanillic acid (HVA) and dopamine beta-hydroxylase (DBH) have been examined in neuroleptic-free and -treated patients, healthy first-degree relatives of the patients and normal subjects. Analysis of variance (ANOVA) revealed significant differences in the concentrations of serum NA(F = 2.91, p < 0.05) and HVA (F = 3.58, p < 0.05), and in the activity of serum DBH (F = 2.77, p < 0.05) among the four groups. The serum NA was significantly higher in neuroleptic-free patients (475 +/- 220 pg/ml, n = 18), than in healthy first-degree relatives (343 +/- 189 pg/ml, n = 37, p < 0.05) or in normal subjects (354 +/- 111 pg/ml, n = 17, p < 0.05), and it also was significantly higher in neuroleptic-treated patients (442 +/- 223 pg/ml, n = 58) than in healthy first-degree relatives (p < 0.05) or in normal subjects (p < 0.05). There was a trend towards high serum HVA in neuroleptic-free patients (11.3 +/- 6.3 ng/ml, n = 17) compared with the other three groups. The serum DBH activity was high in neuroleptic-free patients (31.2 +/- 15.6 nmol/min/ml, n = 17), and significantly in comparison with those treated with neuroleptic drugs (21.6 +/- 10.9 nmol/min/ml, n = 56, p < 0.05). There was a significant negative correlation between HVA concentration and DBH activity in the serum from neuroleptic-free patients (r = -0.64, n = 16, p < 0.01), and there appeared to be three subgroups with alterations of serum DBH activity and HVA concentration.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To determine the value of transesophageal echocardiography in the assessment of prosthetic cardiac valves, 11 patients with clinically suspected cardiac prosthetic valve dysfunction were studied by transesophageal two-dimensional imaging, as well as by color Doppler flow mapping. Among these 11 patients, there were 10 with biological tissue valves and 3 with metallic valves (1 Bjork-Shiley, 2 St. Jude). Nine patients had replacement of mitral valves alone. The remaining two had received both mitral and aortic prostheses. The degree of mitral regurgitation was graded by transesophageal color Doppler according to the area of the regurgitant jet visualized. The degree of aortic regurgitation was graded by the jet height/left ventricular outflow height ratio method. All transesophageal studies were performed without complication and all were well tolerated. The pathological morphology of the cardiac prosthesis was clearly visualized by transesophageal two-dimensional imaging and subsequently proven at surgery. Of those tested, one patient was found to have a torn leaflet, one had a dislodged leaflet, one patient had paravalvular leakage, four had cusp vegetations, and five patients had prosthetic degeneration for other reasons. Mitral regurgitation was graded as absent in one patient, mild in two patients, moderate in two patients, and severe in six patients. Aortic regurgitation was graded as severe in both patients with aortic prostheses. We conclude that in patients with clinically suspected cardiac prosthetic dysfunction, transesophageal two-dimensional imaging combined with color Doppler can provide reliable information that corresponds to surgical findings.

Abstract
For management of obstruction of the extrahepatic portal trunk in patients with healthy livers, we designed an end-to-side anastomosis between the proximal splenic vein and the umbilical portion of the left intrahepatic portal vein and performed a splenectomy to relieve portal hypertension, treat hypersplenism, and restore hepatic portal flow. To our knowledge, no other procedure more adeptly restores original hepatic blood flow. Creation of an anastomosis between the coronary vein and umbilical portion of the left intrahepatic portal vein is an alternative method.

Abstract
The P-20 intragenic marker was used to test for restriction fragment length polymorphisms in unrelated Chinese patients with Duchenne or Becker muscular dystrophy or X-linked mental retardation. In addition to polymorphism at the 6.0/3.5 kb MspI allelic site, we found an independent and high frequency of polymorphism at the 2.2/1.8 kb site. This differs from results found with other populations.

Abstract
For ten years (1979-1989), 150 cases of infantile nephrotic syndrome were treated by integrated TCM and Western medicine (WM). The WM group (50 cases) was treated by conventional WM drugs (prednisone, CLB, etc) and the TCM-WM group (100 cases) was treated by the above-mentioned WM plus treatment according to Syndrome Differentiation with decoction of Chinese medicinal herbs. Wulin San, Zhenwu Tang and Zhibai Dihuang Tang were selected in treating Spleen-Qi Deficiency distressed by Dampness, both Spleen-Kidney Yang Deficiency and both Liver-Kidney Yin Deficiency Syndrome respectively. The total effective rate was 100%, and the efficacy of TCM-WM group was higher than that of WM group (P < 0.005). The efficacy of TCM-WM treatment of nephritic nephropathy was far better than that of simple nephropathy (P < 0.05). Also the efficacy of TCM-WM was superior in raising plasma albumin and reducing blood cholesterol than that of WM (P < 0.001). The cellular immunity function and plasma cortisol of TCM-WM group were significantly improved than that of WM, P < 0.01 and 0.001 respectively. The result showed that the curative effect of the TCM-WM group in treating nephrotic syndrome was much better than that of WM alone.

Abstract
The characteristics change of brain response was studied during 15 degrees head-down tilt (HDT) comparing with 45 degrees head-up tilt (HUT). The brain responses evaluated included the EEG power spectra change at rest and during mental arithmetic, and the event-related potentials (ERPs) of somatosensory, selective attention and mental arithmetic activities. The prominent feature of brain response change during HDT revealed that the brain function was inhibited to some extent. Such inhibition included that the significant increment of "40Hz" activity during HUT arithmetic almost disappeared during HDT arithmetic, and that the positive-potential effect induced by HDT presented in all kinds of ERPs measured, but the slow negative wave reflecting mental arithmetic and memory process was elongated. These data suggest that the brain function be affected profoundly by the simulated weightlessness, therefore, the brain function change during space flight should be studied systematically.

Abstract
This paper describes isolation and identification of a virus (termed strain 87A) which has the cytopathic effect and haemagglutination properties of hepatitis E virus (HEV). This virus was isolated by tissue culture from the faeces of a patient with acute non-A, non-B enteric hepatitis in Xinjiang, China. The isolated virus was neutralized by acute phase sera obtained from other patients with acute non-A, non-B enteric hepatitis. The virus particles also could be specifically aggregated with acute phase sera from patients with known HEV hepatitis in China, Burma, India and the U.S.S.R., and with acute and convalescent sera from an HEV-infected chimpanzee. Crystalline arrangements of virus particles in the cytoplasm were observed by electron microscopy in ultrathin sections of infected cells. The sedimentation coefficient of the strain 87A virus particles in sucrose gradients was 176S. Purified virus particles revealed a protein band of about 76K on SDS-PAGE and Western blotting. The evidence indicates that the strain 87A virus is an HEV. Our ability to propagate HEV in cell culture should facilitate research on this hepatotropic virus.

Abstract
From the amide I bands of their deconvolved FTIR spectra, the S-thiomethyl derivatives of the insulin A, B, despentapeptide(26-30) B and desoctapeptide(23-30) B chains all contain significant amounts of ordered secondary structure. The intact B chain is considerably more ordered than either the A or the truncated B chains. Comparison of the spectra of the separated and mixed intact chains of insulin suggests further folding upon mixing of the chains leading to significant increases in ordered secondary structures, presumably because of stabilization by interaction of the chains. The interactions of the A chain with the DPI B chain appear to be weaker as compared to that with the intact B chain. The above results suggest that only the intact A and B chains contain sufficient structural information to recognize each other and interact to form a native-like structure which make the correct formation of the disulfide linkages possible.

Abstract
The present study demonstrated that plasma IL-6 concentration was higher in older subjects than in younger ones and significantly in the male group (P = 0.02); Spearman rank correlation showed that plasma IL-6 concentration was positively correlated with age (r = 0.28, N = 55, P < 0.05); there was a highly significant correlation between the concentrations in plasma IL-6 and IL-1 alpha (r = 0.51, N = 52, P < 0.001). These findings suggest the possibility that age-related changes of plasma IL-6 and IL-1 alpha may provide a pathological basis for the susceptibility to such illness as commonly occurs in elderly people, especially Alzheimer's disease as the two interleukins can induce the production of alpha 1-antichymotrypsin and beta-amyloid protein precursor.

Two rare cases of nonpenetrating trauma-induced fistula from the right sinus of Valsalva to the right heart chambers are reported. Both were diagnosed preoperatively and operated on successfully. A transverse tear was found in the right sinus of Valsalva, just below the right coronary ostium, in both patients. The ragged inlet and a rough fistula tract were noted during operation. The tears were closed with direct sutures or with a Dacron patch. Coronary artery bypass grafting was needed in 1 patient. The results of operation were excellent.
