Abstract
Objective: Serum anti Müllerian hormone (AMH) was used to evaluate the effect of cyclophosphamide (CTX) on ovarian function in female patients with systemic lupus erythematosus (SLE). Methods: A total of 121 female patients who were 18-50 years old with normal menstruation were selected. Among them, 54 patients were treated with CTX as the study group and the remaining 67 cases as the control group. Before and after treatment for 6 months, the clinical characteristics, menstruation and AMH level of all patients were recorded and detected. At the same time, the method of using CTX and the cumulative measurement are recorded. Results: (1) Before treatment, there was no significant difference in AMH and mean age, duration of disease and SLEDAI score between the CTX treatment group and the control group. The renal injury in the CTX treatment group (44.4%) was higher than that of the control group (34.3%), and the difference was statistically significant (P<0.05). (2) After 6 months of treatment, the AMH of group CTX decreased from (2.39±1.58) μg/L to (1.56±1.42) μg/L, and the difference was statistically significant (P<0.01). But there was no significant change in the control group. In 54 cases of CTX treatment group, 23 cases (42.6%) had different degree of menstrual abnormalities, while 67 cases had only 8 cases (11.9%) in the control group. Moreover, the AMH level of 31 cases with abnormal menstruation was (0.95±0.59) μg/L, which was significantly lower than that of the other 90 normal cases (2.36±1.58) μg/L. (3) In 54 cases of CTX treatment group, the cumulative dose of CTX was less than 3 g in 14 cases, 33 cases of 3-6 g, 7 cases greater than 6 g. AMH was all were lower than those before treatment. But there was a statistical difference between the 3 g group and 3-6 g group before treatment, and there were statistical differences between the groups. Conclusion: CTX can damage ovarian function in women of childbearing age SLE. Low dose intravenous CTX may have less damage. Serum AMH can be used to monitor ovarian function in patients with SLE and to guide individualized treatment.

Abstract
Ganglioside-like structures in CAMPYLOBACTER JEJUNI ( C. JEJUNI) lipooligosaccharide (LOS) can induce antiganglioside antibodies, which might cause nerve damage. In this study, we injected the following three antisera directly into the sciatic nerve of guinea pigs, to investigate the role of anti-glycolipids antibody in inducing neural injury: (i) the wild strain antiserum, a mixture of the sera obtained from the guinea pigs immunized with C. JEJUNI wild-type strain (HS:19) that had a high titer anti-GM1 IgG antibody (range: 800-6,400; median: 2,400) and a high titer anti-LOS IgG antibody; (ii) the GALE mutant antiserum, a mixture of the sera obtained from the guinea pigs immunized with the GALE mutant strain that had only a high titer anti-LOS IgG antibody but no anti-GM1 antibody; and (iii) the control antiserum, a mixture of the sera obtained from the guinea pigs immunized with Freund's complete adjuvant alone which had no anti-GM1 or anti-LOS IgG antibody. Pathological examinations showed that the wild strain C. JEJUNI antiserum produced axonal degeneration in sciatic nerves. Demyelination was rare, and no inflammatory cells were present. The pathological features are consistent with those seen in human patients with axonal GBS. No such changes were observed in nerves injected with the GALE mutant antiserum. The experiment showed that passive transfer of serum containing high titer GM1 antibody caused axonal degeneration of peripheral nerves. The result, which reproduced our previous findings in an active immunization study, therefore further confirmed the critical role of the anti-glycolipid antibody in the induction of neuropathy.

Abstract
Epidemiological studies suggest that bladder cancer may be caused by carcinogens in tobacco and certain occupational exposures. Molecular studies have shown that chromosome 9 alterations and TP53 mutations are the most frequent events in bladder cancer. To date, the relationships between epidemiological risk factors and genetic alterations have not been fully explored in bladder cancer. The purpose of this study was to explore the association between smoking and chromosome 9 aberrations in bladder cancer cases. Seventy-three patients with bladder cancer at Memorial Sloan-Kettering Cancer Center were evaluated for smoking history, occupational history, and chromosome 9 alterations. The epidemiological data were abstracted from medical charts. Patients' tumor tissues were analyzed using RFLP and microsatellite polymorphism assays for detection of chromosome 9 alterations. Elevated odds ratios (ORs) were found for chromosome 9 alterations in smokers compared to those in nonsmokers (OR = 4.2; 95% confidence interval, 1.02-17.0) after controlling for age, sex, race, occupational history, and stage of disease. The ORs were 3.6 for those smoking < or = 20 cigarettes per day and 5.8 for those smoking > 20 cigarettes per day. No association was found between occupational history and chromosome 9 alterations. This study supplies evidence suggestive of the link between smoking and chromosome 9 alterations in the etiology of bladder cancer and indicates that potential tumor suppressor genes on chromosome 9 may be involved in smoking-related bladder carcinogenesis.
