Objective; To investigate the health condition of breast and gynaecology in one university female staff. Method; The breast condition was estimated by mammary gland surgery and mammary gland ultra - red ray , and gynae condition was estimated by gynaeco-logic routine examination, and cervical smear in 586 female staffs of a university. Results; 396 of 586 (68. 72% ) female staffs suffered gynaecologic and breast disease to different degrees. The first four leading disease were chronic cervicitis (32.22% ), colpitis (30.81% ) , hysteromyoma (5. 81% ) and breast hyperplasia (4.75% ). The occurrence of cervicitis in young females was higher than that in the middle aged and aged ( P

Objective To study the relationship between the gene mutations of DNA gyrase subunit A(gyrA)and quinolone resistance in Salmonella typhi. Methods The genes of gyrA DNA of Salmonella typhi S275(a clinically isolated quinolone susceptible strain)and its spontaneous quinolone-re-sistant mutant RGl were examined in this study with polymerase chain reaction(PCR),restrictive frag-ments length polymorphism(RFLP),single strand conformational polymorphism(SSCP)and nucleotide sequencing. Results Nudeotide sequencing of gyrA in Salmonella typhi S275 revealed that the bases of 128～426 kept highly conservative as compared with those of Escherichia coli KL-16,with only 7.49%difference in the gyrA nucleotides 128～426 between the two strains.Most of the mutations were silent mutations,which contributed to 3 amino acid substitutions in gyrase(including Thr-45→His,Arg-49→Leu and Val-56→Gly),and all these substitutions were located outside the quinolone resistance determining re-gion(amino acids 67-106 of subunit A of gyrase).In comparison with Salmonella typhi S275,a single mutation was found at base 247 of gyrA of Salmonella typhi RG1,with change transferred from T to G and led to a substitution of Ser-83→Ala.The mutation might be responsible for the increase of MICs of nalidixic acid,ofloxacin and ciprofloxacin against Salmonella typhi from 2,0.06 and<0.03 to 512,2,and 1 mg/L respectively.Ser-83→A1a was also a newly discovered substitution in gyrA of Salmonella spp.The results of PCR-RFLP and SSCP were in concordance with results of nucleotide sequencing. Conclu.sions The mutation of gyrase at the 83rd amino acid maybe play a principal role in the resistance of Salmonella typhi to quinolone.

There are obvious advantages of the integrated traditional Chinese and western medicine on the treatment of severe acute respiratory syndrome (SARS). Combining the ancient and present literature with the special epidemic patterns, pathological changes and clinical symptoms of SARS, the paper discussed the methods of application of the integrated traditional Chinese and western medicine on the treatment of SARS, and some matters needing attention in clinic.

Airway remodeling is one of the main pathological changes of bronchial asthma. It has shown that a variety of cytokines, including chemokines, growth factors, matrix proteins, participate in and even strengthen airway remodeling through building complex signal transduction pathways. Many traditional Chinese medicines,such as shegan mahuang decoction,have a regulatory role in airway remodeling.

Objective To discuss the relationship between IL-10 genes and susceptibility of H.pylori-associated gastric cancer of Han population in Chongqing district.Methods 100 H.pylori-positive patients with gastric cancer(gastric cancer group)and 140 H.pylori-positive healthy people (control group)were chose in the study,PCR-RFLP method was used to detect the IL-10-592 lo-cus polymorphisms of Han population in Chongqing district.Results Comparing with control group,IL-10-592 genotype frequency distribution of gastric cancer group has statistically significance (χ2=16.36,P<0.05).Logistic regression analysis showed that gastric cancer incidence risk of people carrying with IL-10-592 A/A genotype was OR=4.37(95%CI:2.04-9.38),comparing with the subjects carrying with IL-10-592 C/C.Conclusion Polymorphism of IL-10 gene has close correlated with H.pylori-asso-ciated gastric cancer,IL-10-592 C/C might be the susceptibility gene of H.pylori-associated gastric cancer.

Objective To investigate expression change of Ku70 protein before and after radiotherapy in patients with cervical cancer, as well as its relationship with clinical characteristics. Methods Seventy cervical cancer patients who received three dimensional conformal radiotherapy combined with chemotherapy were registered. Specimens tissues were obtained from cervical tumors of irradiation dose of ≤10 Gy and ≥20 Gy group. Immunohistochemistry was used to detect the expression of Ku70 in 70 cases, and its relative expression was analyzed by image software. Results The relative expression levels of Ku70 in cervical cancer patients treated with radiation doses of ≥20 Gy group (1.31 ± 0.83) and ≤10 Gy group (0.71 ± 0.60) were significantly higher than that before radiotherapy (0.50 ± 0.19), and there was a significant difference (t=7.143, P< 0.01; t= 2.655, P< 0.05). The expression of Ku70 was related with clinical stage, differential degree and tumor diameter (all P< 0.05), but not with age and tumor type (both P> 0.05). The expression of Ku70 in radiotherapy resistant group was significantly higher than that in radiotherapy sensitive group (0.55 ± 0.24 vs. 0.25 ± 0.17, t= 2.979, P< 0.01). Conclusions The expression of Ku70 protein in cervical cancer tissues is increased with the rise of radiotherapy dose. The expression of Ku70 in radiotherapy resistant group is significantly higher than that in radiotherapy sensitive group, indicating that Ku70 protein is correlated with the radiosensitivity, clinical stage, differential degree and tumor diameter.

The initiation of puberty is associated with the hypothalamus-pituitary-gonadal( HPG) axis. The activation of gonadotropin-releasing hormone( GnRH) is the key factor in the initiation of puberty. The initi-ation of puberty is a complicated process,GnRH is under the influence of many associated neuropeptides. Re-cently,the studies have found that GnIH and Kisspeptin can respectively inhibit and promote the hypothalamus GnRH secretion of mammals,indicating that GnIH and Kisspeptin on regulation of reproductive endocrine axis play very important roles. Therefore,GnIH/GPR147 and Kisspeptin/GPR54 pathways may be closely associated with the initiation of puberty.
