Objective To search for the changes of T cells subpopulations and immunoglobulin and their relation-ship in children patients with simple nephrotic syndrome. Design Case-control research. Patients aud Participants 39 patients with simple nephrotic syndrome were divided into two groups:the incipient group and relapse group (6 cases were determined at the incipient and relapse time) .Thereare 28 patients in incipient group, 19 males and 9 females, at the age of 2 to 10 years old. There are20 patients in relapse group, 12 males and 8 females, at the age of 3 to 13 years old. There are 35health children in control group, 21 males and 14 females, 2～13 years old. Interventions T cells subpopulations were determined by indirect immunofluorescence of OKT linesmonoclonal antibodies. The serum IgG was determined by routine simple agar immunodiffusion tests. Results and Conclusions The CD_3~+ and CD_4~+ cells are of no change in the children patients withsimple nephrotic syndrome, and the CD_8~+ and CD_(10)~+ cells are obviously increased, the Values of CD_4~+/CD_8~+ are obviously lower than those in the control qroup, there are no difference between the incipientand relapse groups. The levels of serum IgG were decreased in the 85.3% children patients, IgM were inc-reased in 29.4% of that. The values of CD_4~+/CD_8~+ have positive correlation and negative correlationwith the levels of serum IgG and IgM respectively.

The modern literatures on the diseases treated with acupuncture at Shenmen (HT 7) were collected. Using literature statistical analysis in bibliometrics, the common compatibility of Shenmen (HT 7) and the disease spectrum were analyzed so as to provide the references of the diseases that can be treated with acupuncture at Shenmen (HT 7). It was found that 39 kinds of diseases and symptoms, mainly nerve system disedses, could be treated with acupuncture at Shenmen (HT 7), including insomnia, depression, anxiety and dementia. Shenmen (HT 7) was seldom used alone. Instead, it was commonly used along with Baihui (GV 20), Sanyinjiao (SP 6), Neiguan (PC 6), Sishencong (EX-HN 1) and Taicong (LR 3).

OBJECTIVETo study the edentulous patients facio-maxillary characters, and discuss the base of recording jaw relation by swallowing action.

METHODSForty-three edentulous patients were included in this study, age ranged from 57 to 70 yr, with new comfortable full dentures. Two lateral cephalograms for one patient were taken by SIRONA digital X-ray dental system, one of which was centric occlusion with full denture, another was the end position of swallowing action without denture.

RESULTSThe vertical facial dimensions of male were a little more than that of female. The ratio of lower front facial height/upper front facial height was about 6/5, angle S-N-Po was about 78 approximately 80 degrees. These data may be useful for dentists to make diagnoses if the jaw relation is right or not. Both in vertical or anterior-posterior (horizontal) dimension, the differences between two groups (two actions in one patient) were not significant. It showed that two positions of two actions were the same.

CONCLUSIONSThe SIRONA digital X-ray dental system for cephalometry was swift, and had its own characters. The way of swallowing and occluding is one of efficient methods to record the jaw relation of edentulous patients veraciously and naturally.

OBJECTIVETo establish a new and efficient method(IEDA) for detection of hemorrhagic fever with renal syndrome virus (HFRSV) antigen.

METHODSAn immune enzyme dot assay (IEDA) with mixture of three sorts anti-HFRSV-IgG, which was obtained from rabbit vaccinated with EHFV R22, Chen and Hubei strain was employed to detect HFRSV antigen in serum and urine from epidemic hemorrhagic fever (EHF) patients, and compared with indirect immune fluorescence assay (I-IFA), 76 serum samples and 40 urine samples were detected in this study.

RESULTSThe results showed that the total positive rate of HFRSV antigen detected by IEDA was 73.68% in serum and 65.00% in urine, while that detected by I-IFA was 75.00% and 70.00%, respectively. The positive rate in primary phase (within 5 days) of HFRSV antigen detected by IEDA was 94.34% in serum and 83.33% in urine, while that detected by I-IFA was 64.42% and 55.56%, respectively, there was significant difference in both serum and urine detections. Correlation study showed a high correlation in the result of IEDA and I-IFA.

CONCLUSIONThe results of this study suggested that the IEDA, as compared with I-IFA, was a more specific, sensitive, rapid and simple method with higher positive rate in primary phase. IEDA could be widely used for early diagnosis of HFRS in hospital at grassroots level.

AIMTo investigate the relation between Glu-R and the protective effect of hypothermia on oxygen and glucose deprivation (OGD) injury in hippocampal slices of rat.

METHODS(1) We had established OGD injury model in rat hippocampal slices. The changes of orthodromic population spike(OPS) during OGD and after administration of hypothermia (32 degrees C, 25 degrees C) were observed. (2) We had established Glu excitatory toxicity injury model in rat hippocampal slices. The changes of OPS after exposure to Glu and the effect of hypothermia (32 degrees C, 25 degrees C) against the Glu excitatory toxicity injury were observed. The non-NMDA receptor-mediated excitatory postsynaptic potentials (EPSP) in the CA1 area were recorded via adding the GABA-R specific agonists bicuculline (BMI) and NMDAR agonists D-(-)-2-Amino-5-phosphonopentanoic Acid (AP5) in normal artificial cerebrospinal fluid (nACSF), the NMDA receptor-mediated EPSP were recorded via adding the BMI and non-NMDA-R agonists 6,7-Dinitroquinoxaline-2, 3(1H,4H)-dione(CNQX) in nACSF. The variety of the changes of OPS during OGD14min in nACSF groups and added BMI compounded AP5 or BMI compounded CNQX ACSF groups were observed after administration of 25 degrees C hypothermia 28 min. (3) The changes of ultrastructure of CA1 area after OGD 1 h and the effect of hypothermia (25 degrees C) on it were observed.

RESULTS(1) OPS reduced and abolished quickly during OGD14min, and the recovery amplitude of OPS was very low after reoxygenation/glucose 1 h. While the time of OPS abolishing significantly elongated and the recovery of OPS was higher in hypothermia (32 degrees, 25 degrees C) groups. The effect in groups 25 degrees C was more significant than those in groups 32 degrees C. (2) In control groups, Glu (2 mmol/L, 14 min) decreased the amplitude of OPS, after the end of Glu exposure the recovery amplitude of OPS was very low. After administration of hypothermia (32 degrees C, 25 degrees C), the recovery amplitude and rate of OPS were significantly higher than those in the control groups, while the antagonism on Glu excitatory toxicity injury in H 25 degrees C was more significant than those in H 32 degrees C. The changes of OPS during OGD 14 min were no distinct difference in nACSF groups and added BMI (50 micromol/L) compounded AP5(20 micromol/L) or BMI (50 micromol/L) compounded CNQX (100 micromol/L) ACSF groups. The protection of hypothermia (25 degrees C) could not be cancelled by added AP5 compounded BMI or BMI compounded CNQX in nACSF. (3) After OGD (14 min) 1 h, the nuclear membrane of pyramidal cells in CA1 area was irregular, nucleus were homogenized, the organelle in the cytoplasm was degenerate, even more to necrosis or loss, mitochondrion swelled, ridge was vacuoles. In H 25 degrees C the nuclear membrane was regular, mitochondrion swelled only lightly. Small chromatin gathered to edge.

CONCLUSIONHypothermia shows the protective effects of against OGD injury in hippocampal slices. The mechanism is related to the antagonism of Glu excitor toxicity and maintenance the ATP level in cells, and the antagonism perhaps is mediated by NMDA-R and non-NMDA-R.

OBJECTIVETo investigate the management and prognosis of thyroid well-differentiated carcinoma invading the upper aerodigestive tract.

METHODSA retrospective analysis of the management was performed done 62 patients with thyroid well-differentiated carcinoma invading the upper aerodigestive tract. The main method of surgery was shaving excision, and the other means including partial thyrochondrectomy, total laryngectomy, sleeve tracheal resection, sternocleidomastoid myoperiosteal flap and myodermal flap reconstruction, or simply palliative excision. Some patients received postoperative radioactive isotope therapy and radiotherapy. All patients were followed-up for 2 to 15 years with an average of 6.5 years.

RESULTSThe best curative effect was proved in the patients with local invasion, with the lumen uninvolved and their locoregional control rate was 100.0% (17/17). And the second choice was in patients with more extensive involvement of the upper aerodigestive tract structures. For them, extensive surgical management was done attempting to remove all gross disease followed by reconstruction, their locoregional control rate was 87.5% (7/8). And the third place was designated to patients with local invasion for which shaving excision was performed even though minor residual disease was left, their locoregional control rate was 55.6% (5/9). The poorest result went to simple palliative excision. For 17 patients with minor residual tumor, the locoregional control rate of those who were given postoperative radioactive isotope therapy was significantly higher than those without.

CONCLUSIONAccording to the limits and degree of invasion in the upper aerodigestive tract by thyroid well-differentiated carcinoma, different ways of surgery is indicated. For patients with residual disease, radioactive isotope therapy should be used to improve the result and life quality. Advanced lesions should be given postoperative radio therapy.
