Objective Leucine -rich repeat (LRR) -containing G protein -coupled receptor 6 (Lgr6) is glycoprotein hormone receptor and a part of G protein -coupled receptors (GPCRs).Lgr6 is composed of 977 amino acid residues of a polypeptide chain.Having 17 leucine -rich repeats and seven transmembrane domain.In the N -and C -termini are connected with cysteine -rich sequences.It is highest homologous to Lgr4 and Lgr5,but less relationship with thyroid stimulating hormone receptor,progesterone receptor,and follicle -stimulating hormone recep-tor.Research found out that Lgr6 marks in the hair follicles of stem cells can differentiate into all cells in the skin and Lgr6 expression in tumor also has important biological significance.

Objective To find a indicator in urine to assist diagnosis of cerebral infarction,we investigated the changes of urine ferritin in patients with cerebral infarction.Methods Collected serum from 30 healthy volunteers and 53 patients with cerebral infarction(CI),with ratio of males to females 19∶11 vs.30∶ 23,and average age was (56 ± 11) vs.(63 ± 11) respectively.Collected urine from 39 heathy volunteers and 33 patients with CI,with ratio of males to females 25∶14 vs.20∶ 13,and average age was (57 ± 10) vs.(64 ± 11) respectively.Ferritin concentration in all samples was detected with the chemical luminescence method,and the urine ferritin/urine cretinin (uFer/uCr) ratio was calculated.Differences of serum ferritin and uFer/uCr between healthy volunteers and CI patients were analyzed with the statistical software under Wilcoxon test.Urinary proteins were extracted with absolute ethanol.The extracted ferritin was displayed with Western blot for light chains and heavy chains to investigate the difference between healthy volunteers and CI patients.Results uFer/uCr was higher than that from healthy volunteers (U =292.00,P ＜0.05),and the median was (14.86 vs.6.22) μg/g.Moreover,after extraction of urinary proteins with alcohol,both light chains and heavy chains of ferritin in urine from CI patients were much more obvious than that from healthy volunteers.Conclusion The uFer/uCr ratio could provide a new proof to assist the diagnosis of cerebral infarction.

Objective To study the expression of human giant larvae-1 (Hugl-1) in ovarian carcinoma and its clinical significance.Methods Hugl-1 mRNA expression in 31 ovarian cancer and the corresponding adjacent tissues was examined by real time fluorescence quantitative RT-PCR and in situ hybridization.Moreover,analysis was done while taking into consideration of the clinicopathologic parameters of ovarian cancer.Results The expression of Hugl-1 mRNA in ovarian cancer tissue was significantly higher than that in the corresponding adjacent tissues ([0.051 ? 0.029]vs [0.026 ? 0.043],P

AIM:To explore the inhibitive effects of cervical lymphadenectomy on kerstoplasy after alkaline burns.METHODS:The Wistar rats' corneas were transplanted into Sprague-Dawley(SD)rats' eyes which were randomly divided into 4 groups:group A(control group);group B,the cervicallymphadenectomy group;group C,corneal transplantation after the alkali burn injury;group D,cervical lymphadenectomy following group C.Out of 6 rats in each group,the cornea of one rat Was used for mawophage immunohistochemistry at day 14 after the transplantstion,and the remaining 5 rats were used for studying corneal immune rejection with a slit lamp.The time when allograft rejection occurred was recorded and mean survival times(MST)were compared among the groups.RESULTS:Compared with the MST of group A(10.40±1.14 days),the MST of group B(46.30±9.46 days)Was significantly longer(P＜0.05).MST of grafts between group C(7.00± 1.58 days)and group D(15.00±3.39 days)was also significant (P＜0.05).At 14th day after the transplantation,there was no CD68 immunoreactivity in the graft of group B,and CD68 proteins were expressed to some extent in the grafts of group A and D.However,in the graft of group C,the expression of proteins Was dramatically up-regulated.CONCLUSION:Cervical lymphadenectomy therapy has a significant effect in preventing corneal allograft rejection in normal and alkali burned oorneai beds.

In order to find an easy and rapid quantitative analytical method to detect rhamnolipid produced by Pseudomonas aeruginosa, three methods, H_ 2 SO_ 4 -anthrone analysis method, L-cysteine-H_ 2 SO_ 4 method and phenol-H_ 2 SO_ 4 method, were compared in the present paper, and the influence factors were also considered.The results showed that H_ 2 SO_ 4 -Anthrone analysis method was better than the others and its optimal reaction condition was obtained.The influence to the quantitative analysis of rhamnolipid from the residual glucose and the top clean liquid layer in the ferment solution could be ignored.But the influence from the bacterial body and the middle layer of the ferment solution reached a certain degree.Thus, the bacterial body should be removed before measuring.However, the influence from the middle layer of the ferment solution could be avoided by making a standard curve which was made by using a rhamnose mixed with the middle layer ferment solution.

Objective To further research the urinary monitoring of the maternal thyroid functional status ,the levels of urine thyroid hormones were analyzed during pregnancy .Methods This study recruited 30 cases of healthy pregnant women at 9-12 ges-tational weeks .Their random urine specimens were collected every four weeks until delivery .The concentrations of urine thyrotro-pin(uTSH) ,urine free triiodothyronine(uFT3) and urine free tetraiodothyronine(uFT4) were detected by electrochemical lumines-cence immunoassay(ECLIA) .The urine retinol binding protein(uRBP) was detected by enzyme immunoassay (EIA) .After correc-ted by uRBP ,the statistical analysis was done to analyze the variation of the ratio of uTSH and uRBP (uTSH/uRBP) ,the ratio of uFT3 and uRBP(uFT3/uRBP)and the ratio of uFT4 and uRBP(uFT4/uRBP)during pregnancy .Results The median levels of u-rine thyroid hormone parameters were obtained from the healthy pregnant women every four weeks and were compared among dif-ferent stages .The difference of uFT3/uRBP and uFT4/uRBP was statistically significant (F= 6 .222 ,P< 0 .05 ;F= 5 .078 ,P<0 .05) ,and the levels of them varied linearity during pregnancy (F=27 .480 ,P<0 .05 ;F=23 .959 ,P<0 .05) .The difference of uT-SH/uRBP had no statistical significance(F=2 .731 ,P=0 .054) .Conclusion After corrected by uRBP ,the levels of uFT3 and uFT4 of healthy pregnant women decreased linearity among different gestational stages ,and the levels of uTSH had no noticeable change .

Objective To investigate the relationship between the expression of β-catenin and drug-resistance mechanism of choriocarcinoma according to the expression of β-catenin in JEG-3 cells (human choriocarcinoma cell line) and drug resistant JEG-3/VP16 cells.Methods The mRNA and protein expressions of β-catenin were analyzed with reverse transcription-polymerase chain reaction(RT-PCR) and Western blotting.Flow cytometry was used to determine the percentages of β-catenin-positive cells in the two choriocarcinoma cell lines.Results Both drug resistant choriocarcinoma cells and drag sensitive cells were found to express β-catenin; but the expression of β-catenin mRNA (1.43 ±0.24) and protein(1.49 ±0.17)in drug resistant choriocarcinoma cells was found much higher than that in drug sensitive cells(0.65 ±0.14,0.66 ±0.16,P ＜0.01).And according to detect by flow cytometry,we found the number of β-catenin-positive cells in JEG-3/VP16 cells [(40.13 ±5.17) ％] was much more than that in JEG-3 cells [(13.15 ± 1.48) ％,P ＜ 0.01].Conclusions β-catenin was highly expressed in the drug resistant choriocarcinoma cell line (JEG-3/VP16).It indicates β-catenin might be involved in the drug resistance mechanism of choriocareinoma.

By summarizing and analyzing the clinical diagnosis and treatment experience of 17 cases of adrenal lymphangioma, the imaging characteristics and pathological types of the disease were discussed. The results showed that the imaging of adrenal lymphangioma was non-specific, and the appearance was similar to that of general cysts.Howerer, the density of the cyst was slightly higher than that of simple cysts. Some cases showed calcification on the cyst wall, and a few showed adenoma-like appearance. The diagnosis mainly depends on pathological examination. For those patients with tumors ≥4.0 cm, endocrine function, suspected malignancy, or obvious clinical symptoms, surgery is recommended.
