In recent years, drug resistance of Candida albicans is on a rise in clinical practice. Gene chip technique is the most commonly used means to map gene expression profile in drug resistant Candida albicans. Gene chip can be used to analyze the differentially expressed genes in drug resistant Candida albicans strains induced by various procedures. The drug resistant genes can be identified and their functions can be further studies. The results of gene chip study can also play a role in studying the mechanism of synergism of multiple drug resistance genes.

Using colon adenocarcinoma cell line HT-29 as testing material, adhesion test was carried out for 24 strains of Bifidobacteria isolated from dejecta of longevous people aged one hundred years. The results showed that all strains could adhere to colon adenocarcinoma cells HT-29, among which the strains of TTF, Z2, TZ5 and (J-1) showed higher adhesive capability. Thus these four strains of Bifidobacteria were further tested for their endurance to stomach acid and bile acid. The production of vitamin B by these bacterial were also tested. All these tests indicated that the strain of TTF has high ability to produce Vitamin B_(1), B_(2), B_(6), B_(12), The survival rate after the treatment under pH 3.0 for 120 min was 93.11%, at the same time, the strain TTF can survive after being treated with 2% bile acid for 24h.

OBJECTIVETo observe the effect of Guilingji Capsule (GC) on the fertility, liver functions, and serum lactate dehydrogenase (LDH) of adult male SD rats exposed by 900 MHz cell phone.

METHODSTotally 18 adult male SD rats and 36 adult female rats in child-bearing period were selected and randomly divided into three groups according to weight equilibrium principle, i.e., the normal group, the radiated group, and the GC group, 6 males and 12 females in each group. Male rats in the normal group and all female rats were not radiated. Male rats in the radiated group and the GC group received radiation for 4 h per day, lasting for 18 successive days. Rats in the GC group received GC suspension at the daily dose of 0. 15 g/kg by gastrogavage at the same time. Equal volume of normal saline was administrated to other male rats. Then male rats were mated with corresponding female rats from the 14th radiation night to the 18th radiation night in the ratio of 1:2. Male rats were killed following on the next morning of ending the radiation. Female rats were normally fed and then killed before delivery. The pregnant outcomes of female rats in responding groups (the rates of pregnancy and the number of death fetus, birth weight, body length, and tail length) were observed and compared. Serum alanine aminotransferase (ALT), aspartate transferase (AST), AST/ALT, and LDH levels of the male rats were detected by colorimetry. Histological and morphological changes of liver were observed by HE staining.

RESULTSCompared with the normal group, the pregnancy rates of female rats decreased and the number of death fetus increased, the serum LDH level obviously increased in the radiated group (P < 0.05). Serum levels of ALT, AST, and AST/ALT were no significantly changed in the radiated group. The hepatocyte nuclear atrophy and cytoplasm vacuolar degeneration appeared. Compared with the radiated group, the pregnancy rates increased, the number of death fetus dropped, and the serum level of LDH decreased in the GC group (P < 0.05). There was no obvious change in serum levels of ALT, AST, or AST/ALT. The hepatocyte nuclear atrophy and cytoplasm vacuolar degeneration were significantly attenuated. The histomorphological structures recovered to normal basically in the GC group.

CONCLUSIONSThe pregnancy rates could be decreased, the number of death fetus increased, histomorphological structures abnormal, and serum LDH level increased by exposure toy GSM 900 MHz cell phone. GC could prevent and treat the aforesaid lesion. But there was no statistical difference in serum ALT or AST levels.

Objective To analyze the results of the Objective Structured Clinical Examination(OSCE) of medical interns in Department of Gynecology and Obstetrics,and to assess the role of OSCE in clinical teaching and practice. MethodsAtolal of 104 medical interns of five-year education program in 2002 and seven-year education program in 2003 in School of Medicine had taken part in OSCE of gynecology and obstetrics.The OSCE consisted of six stations: gynecologic examination,obstetric examination,oral test,interrogation of standardized-patients(SP),drawing partogram,and non-stress test(NST) explanation.After gathering the data of each station,the software of SPSS 11.0 was used to make statistical analysis. Results The median scores were as follows: 92.0 for gynecologic examination,91.0 for obstetric examination,83.5 for oral test,80.0 for interrogation of SP,80.0 for drawing partogram,and 70.0 for NST explanation.There was no significant impact of familiarity to OSCE on the results of the test.The results showed that medical interns did good job in basic performance,but lack of clinical practice skills in some complicated practice of gynecology and obstetrics.Conclusion The grading system and stations setup of OSCE in Department of Gynecology and Obstetrics in Shanghai Sixth People's Hospital show objectivity and equity.The OSCE can be widely applied in the after-department examination and even graduation examination.

AlM: To explore a formula between the diopter , cornea diopter ( CD ) , anteriou chamber depth ( ACD ) , lens thickness ( LENS ) , vitreous depth ( VlTR ) , and ocular axis longitude ( AL ) of high school students in certain middle school, and to predict the diopter with the biometry data of refractive factors on the students. METHODS: The related ocular examinations were performed to 364 eyes of 182 high school students in certain middle school by cluster sampling method. Optometry was for diopter and A-ultrasonic biometry was for ACD, LENS, VlTR, and AL.

OBJECTIVETo investigate the change of JNK and c-Jun in lung injury associated with paraquat poisoning of rats.

METHODS46 Rats were randomly divided into four groups: PQ group (n = 12), control group (n = 10), PQ + ZnPP group (n = 12) and PQ + Hm group (n = 12). The rats were injected with 2% PQ (25 mg/kg, ip) in PQ group. ZnPP and Hemin (10 mg/kg, 10 mg/ml) were injected through inguinal vein before intraperitoneal administration of 2% paraquat in PQ + ZnPP group and PQ + Hm group respectively. The rats were injected NS (1 ml/kg, ip) in control group. HE dyeing of lung tissue and MDA content of plasma were used for estimating the injury of lung tissue. The content of CO in the lung tissue was determined. The expression of HO-1 mRNA of the lung tissue was detected by the reverse transcription-polymerase chain reaction. The phosphorylation of JNK and c-Jun was evaluated by Western blot analysis.

RESULTSThe degree of lung injury in PQ group and PQ + ZnPP group was higher than that in control group and PQ + Hm group. But in PQ + Hm group the degree of lung injury was lower. The content of MDA in PQ group and PQ + ZnPP group was higher than that in control group and PQ + Hm group (P < 0.01). The content of MDA in PQ + Hm group was higher than that in control group (P < 0.05). The content of CO in lung tissue in PQ group, PQ + ZnPP group and PQ + Hm group was and (1.08 +/- 0.15 mg/L) respectively, and higher than that in control group (P < 0.01). The content of CO in lung tissue in PQ + Hm group was significantly higher than that in PQ + ZnPP group (P < 0.01). The expression of HO-1 and the phosphorylation of JNK (55.24 +/- 9.34, 38.15 +/- 10.71, 128.55 +/- 19.43) and c-Jun (23.16 +/- 4.85, 15.49 +/- 3.13, 44.89 +/- 10.37) were increased remarkably in PQ group, PQ + ZnPP group and PQ + Hm group. Those in PQ + Hm group were higher significantly than PQ group and PQ + ZnPP group (P < 0.01). Those in PQ + ZnPP group were lower than PQ group (P < 0.05).

CONCLUSIONThe increase of CO of lung tissue in rats at the lung injury associated with paraquat poisoning reduces the acute lung injury of rats. The level of JNK and c-Jun phosphorylation increases obviously, especially after Hemin is utilized.
