Objective To explore the changes of estrogen receptor (ER) and progesterone receptor (PR) in the endometria of pro-liferative phase in polycystic ovary syndrome (PCOS) patients. Methods Thirty-two patients who suffered PCOS combined with infertilitas feminis were enrolled in this study, and 20 cases of tubal infertilitas feminis having the corresponding time period were selected as controls. The expressions of estrogen receptor (ER) and progesterone receptor (PR) in the endometria were observed by pathological examination and immunohistochemical staining. Results The expressions of ER and PR in the PCOS group in the glands and interstitium of endometrial a-mong three different periods were not significantly different. The expressions of ER and PR in the glands and interstitium of endometrial a-mong three different periods in the control group were significantly different. There was no statistical difference in the expressions of ER, PR in the glands and interstitium of the early endometria between PCOS group and control group. The expressions of ER in the glands and inter-stitium of the middle endometrial in PCOS group was significantly lower than that of control group. The expressions of ER and PR in the glands and interstitium of the late proliferative endometrial in PCOS group was significantly lower than that of control group. Conclusion ER and PR of endometrial in the PCOS patients decreased. The cyclical of ER and PR in the PCOS patient were irregular.

Objective To investigate the characteristics of clinical manifestations,treatment and prognosis of patients with systemic lupus erythematosus (SLE) complicated with central nervous system (CNS) infoction.Methods The medical records of 30 patients with SLE complicated with CNS infeetion were retrospectively reviewed.Results In the cohort of 3039 SLE patients admitted during last 20-year8,30 patients (1%) were identified with CNS infection.The mean age of patients with CNS infection was (34±11) years.Twenty-seven (90%) out of the 30 patients were fomale.Patients could be divided into 3 groups based on the offending microorganisms:mycobacterium tuberculosis (TB),non-TB bacterial and fungal infection groups respectively.TB infection was identified in 11 patients (37%),non-TB bacterial infections could be confirmed in 11 (37%),and fungal infection in 8 (26%).The most common presentations of CNS infeetion were fever,headache,and conscious level changes.There was no difierence among the three groups in morta-lity rate.Conclusion The clinical presentations of SLE patients complicated with CNS are generally atypical.Tubereulosis meningitis is the most prevalent CNS infection in patients with SLE.CSF analysis should be done as soon as possible for establishing early diagnosis.A lOW sernm albumin level,low C3 level and a low intracranial pressure predicts for unfavorable outcomes.

Objective To analyze the feasibility of the recombinant cholera toxin B subunit (rCTB) as a carrier protein candidate for the preparing of polysaccharide-protein conjugate, and to discuss the immune effects of tetanus toxoid (TT) as the carrier protein in mucosal delivery vaccine. Methods The refolded pentrumer protein, rCTB was obtained by genetic engineering methods. Then conjugated the refold-ed protein with group A meningococcal polysaccharide (GAMP) using the chemical method(ADH) ,the pol-ysaccharide-protein conjugates(GAMP-rCTB) were prepared. BALB/c mice were immunized either intraper-itoneally ( i. p. ) or intranasally ( i. n. ) with GAMP-rCTB. Moreover, GAMP-TT vaccine that TT as carrier proteins was i.n. immunized to the mice. The evaluation of immunology is performed. Results The conju-gates of polysaccharide-potein with the rCTB and TT as protein carrier both are able to elicit high level of GAMP specific IgG antibody in serum after i.n. immunization, and the conjugates can also elicit specific IgA antibody in lung lavage and intestinal mucosa. Conclusion rCTB and TT can both as the protein carri-er for polysaccharide-protein conjugate as mucosal vaccine. The route of intranasal may be more ways for im-mune function than i.p. immunization when rCTB is used as the carrier of the polysaccharide-protein conju-gates.

Objective To explore the distinction between measles vaccine strain Shanghai-191 (S- 191) and wild-type strains in China at molecular level. Methods After having been amplified by RT-PCR, the nucleotides of S-191 was sequenced and analyzed with reference to the sequences obtained from Gen- Bank, which includes 24 whole genome sequences, 211 sequences of wild-type strains isolated from China and WHO reference strains. Results The sequence of S-191 strain had been submitted to GenBank. Phylo- genetic analysis of the COOH terminal 456 nucleotides coding for the nucleoprotein (N) indicated that most of the measles virus strains from China were members of clade H1. The genetic distances between the virus strains detected in a number of provinces and S-191 strain were 6.7% -8.2%. It is noteworthy that the muta- tion rate of non-coding regions was considerably higher than that of coding regions. The mutation rate of N gene was the highest among all of the coding regions. Conclusion This report shows that genotype H1 is widely distributed throughout the country. The circulation has no apparent geographic and temporal restric- tion. The evolution of measles virus should be closely followed.

Objective: To investigate the optimal gene transfer protocols of hematopoietic cells mediated by retrovirus. Methods: Murine bone marrow cells were infected by co-culture with murine bone marrow stromal cell line TC-1 or retro-virus packaging cells or retrovirus supernatant. Human mdr-1 and enhanced green fluorescent protein (EGFP) were used as report genes. Results: Stromal cells could greatly increase the gene transfer efficiency when compared with that of supernatant transfection. Transduction efficiency was highest when infected BM cells were co-cultured with virus producer cells. Conculsion: It may be clinically feasible in gene therapy to perform retroviral transduction by co-culture of target cells with stromal cells or cell lines.

Methods Among the 24 cases of Laparoscopic adrenalectomy tumors, there were 8 cases of adrenal adenoma, 7 cases of pheochromoeytoma and 9 eases primary aldosteronism. Results One ease was transit to open operation, the other 23 were successful,each surgerical time was 40～130 min with an average of 98 rain. Hemorrhage was 50～300 mL, 140 ml average, no blood transfusion. It was 1～2 d after sur- gery to remove drainage tubes, and could take some activities and have fresh flow in the second day. The pa- tients didn't appear complications and discharged after 5～7 d. Follow-up of 6～24 months, there was no recurrence and long-term complications. Conclusion Laparoscopic adrenalectomy has the advantages of minor trauma surgery, less bleeding, good demonstrating, convenient operation, fewer complications and quick recovery.

Objective To establish the reference intervals of serum osteocalcin (OCN), C-terminal cross-linking telopeptide of type Ⅰ collagen (β-CTx) and total type Ⅰ procollagen N-terminal peptide (P1NP) by electrochemiluminescence assay. Methods According to the Clinical and Laboratory Standards Institute (CLSI) "CA8-A" document the appropriately healthy people, who were divided into three groups (men, premenopausal women, and postmenopausal women) by sex and pre- or postmenopausal status were screened. The levels of fasting serum of OCN,β-CTx, tPINP were detected by Roche Modular E170 electrochemical immunoassay. Results 393 appropriately healthy people consists of 112 men between the ages of 29 and 69 years, 148 premenopausal women between the ages of 29 and 69 years, 133 postmenopausal women between the ages of 29 and 69 years. The levels of serum OCN, β-CTx, tP1NP in men group were (15.33±4.76) μg/L, (413±189) ng/L, (42.15±17.14) μg/L, respectively. The levels of serum OCN, β-CTx, tP1NP in premenopausal women group were (12.99±4.53) μg/L, 265(30-820) ng/L, (36.43±14.23) μg/L, respectively. The levels of serum OCN, β-CTx, tP1NP in postmenopausal women group were (18.96±5.15) μg/L, (513±195) ng/L, 51.40 (8.98 -118.6)μg/L, respectively. Logarithmic transformation produced normal distributions for all markers but serum β-CTx of premenopausal women group and serum tPINP of postmenopausal women group. The 95% of the distribution intervals for serum OCN, β-CTx, tP1NP in men group was 6.00-24.66 μg/L, 43-783 ng/L, 9.06-76.24 μg/L, respectively. The 95% of the distribution intervals for serum OCN, β-CTx, tP1NP in premenopausal women group was 4.11-21.87 μg/L, 68-680 ng/L, 8.53-64.32 μg/L respectively. The 95% of the distribution intervals for serum OCN, β-CTx, tPl NP in postmenopausal women group were 8.87-29.05 βg/L, 131-900 ng/L, 21.32-112. 80 μg/L, respectively. Conclusions Compared with the reference intervals provided by manufacture, the reference intervals of three serum bone turnover markers established by our laboratory have great difference. Laboratory should pay attention to the reference intervals was cited.

Objective To explore the effects of deoxynivalenol (DON) on apoptosis of human gastric carcinoma cell line SNU in vitro. Methods SNU cells were treated with DON at different concentrations (50, 100, 1000, 2000 μg/L) for 12 hours, and then cells were harvested for cell apoptosis by flow cytometric (FCM) DNA analysis and the expression of Bax, Bcl-2 and Caspase-3 at protein level with FCM and Western blotting. Results FCM results showed that the apoptosis rates of SNU cells in DON treatment groups were all higher than that in control, especially in DON 1000 μg/L and 2000 μg/L groups (P<0.05). In the concentration range from 50 to 2000 μg/L, a significant concentration-depended response correlation could be found between apoptosis rate and DON concentration (r =0.940, P <0.01). FCM and Western blotting showed Bax and Caspase-3 expression in often SNU cells DON treatment for 12 hours were up-regulated while that of Bcl-2 was down-regulated. Conclusion DON can induce apoptosis of SNU cells in vitro in dose-dependent manner, and possible mechanisms of apoptosis induction effects may be up-regulation of the expression of Bax and down-regulation of that of Bcl-2 and activation of the key enzyme of apoptosis Caspase-3.
