Serum concentrations of sialic acid, fucose, prealbumin(PA ), ?1-antitrypsin (?1-AT), ?1-acid glycoproteins(?1-AGP), haptoglobin (HP) and transferrin (TF) were measured in 94 nasopharyngeal carcinoma and 65 cancer of larynx. Statistical evalution was made with stepwise discriminant analysis, and the discriminant functions were obtained. The effectiveness of allocation were examined on every one of all patients in the original data, Our results suggested, with the discriminant function equation consisting of serum PA, ?1-AT, ?1-AGP, HP and TF concentrations we could best separate the patients sufferng from nasopharyngeal or laryngeal carcinoma from the normal; the effective rate of discriminant was 87.36% and 88% for nasopharyngeal carcinoma from normal and laryngeal carcin-oma from normal respectively. However using discriminant function equation,composed of serum sialic acid, PA and ?1-AT, we could also discriminate nasopharyngeal or laryngeal carcinoma with recurrence from the one with non-recurrence, the effective rate of discriminant was 93.1% and 80% for nasopharyngeal carcinoma and cancer of larynx respectively

In this paper, we reported the radiographic characteristics of arterio-portal shunt in 59 cases with hepatocellular carcinoma. All eases were arbitrarily divided into three types, the peripheral, central, and mixed. The angiographic manifestations of all types were described in detail with emphases on discusion of the mechanism of the pormation of arterio-portal shun, and the orientation of interventional approach. We suggested that active and solemn attitude should be taken but with different ways be considered rather than ignoring it, for obtaining the positive results.

In this paper EEGs spectral analysis and computer recognition method have been applied to 20 children from the Zashue County of Shaanxi Provence, who are suffering from mental retardation of endemic etiology unknown. The results of the experiment show that the energy ratio of DELTA and THETA bands increases and that of ALPHA band dicreases. The total energy of all bands becomes smaller than the contro group. The patterns of EEG suggest that some particular pathological damage should occur in these children. The obvious advantages of using computer analysis may be the indexes to diagnosis this kind of disease.

The relation between improved water supply and entro-infectious diseases was studied with cross-section and self-control study methods'the results showed an significantly decreased mobidity of entro infectious diseases in areas with improved water supply compared with with those with scaltering water supply,so did the coliform counts in waters,Which showed that improved water supply if of great significance for decreasing entro-infectious diseases morbidity.

Studies of the scalps from 42 patients with alopecia areala are given,using direct immunofluorescence ( DIP).Langerhans cells (LC)and T-lyrn hocytc subsets are observed.There is no significant difference between the number of OKT6 cells and Ia+ cells in the epidermis of all groups and the control.LC is seen in hair-bulb in many patients and most frequently in active stage.The main change of LC in hair follicle is increasing of T6+Ia- cells,not significant of T6+Ia+ cells.Most of the infiltrates around the hair follicles are T( OKT3+) cells.T4+cells number and T4/T8 ratio in active arc larger than in resting and recovering stages.DIF shows 88% of the patients having deposits of C3,IgG,and IgM.This suggests that alopecia areata may be the disorder of immnue associated with cellular and humoral immunity.

The aims of this study are to obtain a suilablc condition for the cardioplasty with the fundoplication and an observation of the effect of the antircflux function following the operations. The results show that a suppcrting dcvicc of a round tube with 1 - 1.2 ctn diamcter is used as a guide to establish a good lovver esophageal sphinctcr(LES). The experimental ani-mais may survive very long. The pressure in the sphimcter is cvenly the same as that after the operation immediately. The gastroesophageal reflux is never occurred except intragastric pres-sure is the same as or higher than LES. The lower csophagcal high pressure zone formed is similar to the smooth muscle in the lower part of csophagus at the sile of opcralions . The new formed cardia plays an excellent role of anturc flux function . This report suggists that the cardioplasty with fundoplication is useful for the treatment of esophageal achalasia and somc other abdpminal disorders.

Three crystals (Ⅰ, ⅡandⅢ) were isolated from Galeola shweliensis W.W. Sm. and identified by means of physical nd chemical properties, and spectral data. It shows that crystal I was a novel com-pound, named galeolate (CH3-(CH2)12-C-O-CH2 -(CH2)12-C-O-C-CH3). Crystal ⅡandⅢwere confirmed as steanc acid and ?-sitosterol, respectively. These three constituents were found inthis plant for the first time.

Objective:To explore the relationship between genetic polymorphism of ALDH2 and CYP2E1 and alcoholic liver disease(ALD) in Han people. Methods:PCR-RFLP was used to detect the frequencies of gene types and allele of ALDH and CYP2E1 in health control group(45 cases),ALD group(48 cases),alcohol dependent group(38 cases) and non-ALD(NALD) group(42 cases),and the frequencies were compared. Results:The difference of the frequencies of ALDH2*1 and ALDH2*2 had statistic significance between health control group and ALD group,and between in ALD group and NALD group(P

This article presents an advanced dental diagnostic instrument-the pre-pain sensation electric pulp tester with current indication. The tester adopts an alternating current signal generator with a specific frequency as the stim- ulating source which can induce a pre—pain sensation similar to a cool-sour feeling or tingling without causing any pain when the current flows through the patient's dental pulp.The dentist can judge the vitality of the dental pulp by the data displ.ayed on the tester.The tester is superior to other similar instruments both at home and abroad with its better accuracy and repeatability. This instrument adopts the integrated circuit and some other new techniques such as automatic boost,automatic switching on and off of the power and automatic data-holding. Compact,light and easy to operate it has high reliability,safety and low power consumption. At present,it is a more advanced dental electric pulp tester.

Objective: design knee prostheses infection modal for rabbits. Methods:The knee implants were designed with 3mm To Kirschner wire for the length of 15mm.Implanted the stem to the distal femoral through intercondylar fossa.forty eight rabbits were divided into 4 groups randomly,12 in each group and finished above-mentioned surgery. Immediately after the surgery,0.5 ml 1?107 CFU of Staphylococcus aureus ATCC 25923 was injected into the joints of group A,0.5 ml 1?106 CFU in group B and 0.5 ml 1?105 CFU in group C, group D were not injected.the animals were sacrificed 2 weeks after injections, wounds were observed and X-ray films were and taken. levels of serum CRP and ESR determined,pathological changes were observed and bacteria cultures were performed. Results: After staphylococcus aureus was injected into the joints right after the surgery.100% knee joint infection in group A and 100%in group B, 83.3% in group C,none knee joint infection in group D. A large amount of inflammatory cells were found in the infected samples, theand levels of serum CRP and ESR were elevated in the infected samples. Conclusion:An animal model of TKA infection can be established successfully at 2 weeks by 0.5 ml 1?106 CFU staphylococcus aureus ATCC25923 injecting into the joints immediately after the surgery.
