Chinese Journal of Primary Medicine and Pharmacy 2013;20(21):3251-3253
Objective To discuss the application value of cancer gene c-erbB-2 and its protein products P185 in evaluation of the diagnosis and prognosis of breast cancer with lymph node metastasis,and to explore the relationship between c-erbB-2 expression and tumor pathology classification,relapse.Methods 112 cases with mammary disease were selected as the research subjects.According to different clinical diagnosis,they were divided into breast cancer lymph node metastasis group,breast cancer without metastasis group and mammary gland benign pathological change group.The c-erbB-2 gene and carcinoembryonic antigen(CEA) were detected by immunohistochemical method,enzyme-linked immunosorbent(ELISA) and electrochemical luminescence method.The c-erbB-2 protein(P185)and CEA of the three groups were compared,the sensitivity and specificity of c-erbB-2 expression and CEA in the diagnosis of breast cancer with lymph node metastasis were analyzed.At the same time,the relationship between cerbB-2 expression and tumor pathology classification,relapse was analyzed.Results P185 and CEA index of breast cancer lymph node metastasis group and breast cancer without metastasis group were significantly higher than those of mammary gland benign pathological change group(t =7.093,6.443,9.232,8.508,all P < 0.0 1),and P185 index of breast cancer lymph node metastasis group was significantly higher than without metastasis group (t =2.281,P <0.05),and there was no significant difference of CEA between the two breast cancer groups (t =0.406,P > 0.05).The sensitivity of c-erbB-2 expression in dignosis of breast cancer lymph node metastasis had no difference with CEA (x2 =0.632,P > 0.05),but the specificity was significantly higher than CEA(x2 =11.900,P < 0.01).The positive expression rate of c-erbB-2 and tumor pathology classification had no obvious relation:Postoperative recurrence rate of c-erbB-2 positive expression patients was significantly higher than the negative expression patients(x2 =5.141,P <0.05).Conclusion c-erbB-2 gene and its protein product has good sensitivity and specificity in the diagnosis of breast cancer lymph node metastasis,and has obvious correlation with postoperative breast cancer recurrence,has important reference value in evaluation of the diagnosis and prognosis of breast cancer.

6.Muscular expression of myogenin in V-pattern exotropia with inferior oblique overaction patients
International Eye Science 2015;(1):162-164
Abstract?AlM: To study the number of myogenin - positive activated satellite cells in the inferior oblique muscles and the medial muscles of V- pattern exotropia with inferior oblique overaction, to further explore the possible etiological factors of V-pattern exotropia with inferior oblique overaction.? METHODS: The inferior oblique muscles and the medial muscles were cut from V - pattern exotropia patients with inferior oblique overaction during strabismus operation treated as the strabismus group. Cross sections were stained immunohistochemically for the presence of activated satellite cells, as identified by myogenin immunoreactivity. The inferior oblique muscles and the medial muscles were obtained from the corneal transplant donors ( six eyes of six cases) , which treated as the control group.? RESULTS: The frequency of myogenin - positive satellite cells of the inferior oblique muscles was (22. 7± 7.03)% and (4. 2±0. 75)% in the strabismus group and the control group. Significant differences existed in the expression of myogenin in two groups (P<0. 05). Again, the frequency of myogenin-positive satellite cells of the medial muscles was (2. 2±0. 75)% and (4. 5±1. 05)% in the strabismus group and the control group. Significant differences also existed in the expression of myogenin in two groups (P<0. 05).?CONCLUSlON: lt is first report that myogenin-positive satellite cells presents in extraocular muscles of V -pattern exotropia with inferior oblique overaction. The current results suggest that myogenin is one of possible etiological factors of V-pattern exotropia with inferior oblique overaction.

Clinical Medicine of China 2016;32(4):312-315
Objective To explore the relationship between the times of abortion and congenital and acquired uterine anomalies.Methods One hundred and eighty-five patients underwent diagnostic hysteroscopy following abortion were selected and diagnosed by hysteroscopy,then divided into congenital and acquired uterine abnormalities according to the morphology and the formation of uterine cavity lesions.The relationship of 1 times,2 times,equal or more than 3 times of different number of abortion and uterine congenital and acquired abnormalities were compared respectively.Results Diagnostic hysteroscopy revealed anomalies uterine cavity was 79.9% (148/185),of them congenital uterine anomalies was 52.4% (97/185),and acquired uterine pathologies was the most of 21.1% (39/185),acquired uterine abnormalities was 21.1% (39/185),and intrauterine adhesion was the most common of 11.9% (22/185).Incidence of intrauterine adhesions of natural abortion with 1 times,2 times and 3 times or more were 7.4% (5/68),14.1% (11/78) and 15.4% (6/39).Hysteroscopy showed that the detection rates of normal uterine cavity,congenital abnormalities,acquired uterine and congenital and acquired pathologies in 3 groups were 27.9% (19/68),51.5% (35/68),17.6% (12/68)and 2.9%(2/68);17.9%(14/78),51.3%(40/78),24.3%(19/78) and 6.4%(5/78);10.3%(4/39),56.4% (22/39),20.5% (8/39) and 12.8% (5/39),respectively,the differences were not significant (x2 =8.823,P=0.184).Conclusion Hysteroscopy is a simple and efficient tool in the early diagnosis of congenital and acquired uterine anomalies.Diagnostic hysteroscopy can be performed after the first miscarriage in order to early diagnose and treat congenital and acquired uterine pathologies.
8.Content Determination of Fe in Iron Dextran Preparations by UV-VIS
China Pharmacy 2001;0(10):-
OBJECTIVE:To establish the ultraviolet visible spectrophotometry(UV-VIS)for the determination of Fe content in iron dextran preparations.METHODS:Under the acidic condition,Fe~(3+)was dissociated from iron dextran solution by heating,then Fe~(3+)was deoxidized into Fe~(2+)by hydroxylamine hydrochloride,and red Fe~(2+)-orthophenanthroline complex was formed through combination with o-phenanthroline.The content of the Fe~(2+)-orthophenanthroline complex was determined by UV-VIS at a wavelength of 510 nm.RESULTS:The linear range of Fe~(2+)was 0.5~4.0?g?mL~(-1)(r=0.999 9). The average recoveries of two preparations(tablets and injection)of iron dextran were 99.8%(RSD=0.52%)and 99.7% (RSD=0.44%),respectively.CONCLUSION:The UV-VIS method is simple,accurate in results and applicable for the determination of iron dextran preparations.

10.Clinical Analysis of 12 Cases of Intrauterine Re-adhesions Treated with Transcervical Resection of Adhesion
Chinese Journal of Minimally Invasive Surgery 2016;16(10):911-912,916
Objective To study the clinical characteristics of intrauterine re-adhesions treated by transcervical resection of adhesion (TCRA). Methods Between January 2012 and January 2015, 12 patients with intrauterine re-adhesions after TCRA in other hospitals had fertility requirements , including 10 cases of severe intrauterine adhesions and 2 cases of moderate intrauterine adhesions .In our hospital , the 12 patients underwent laparoscopic exploration and TCRA .After operation the patients were treated with artificial cycle therapy for 3 months and then underwent hysteroscopic examination . Results In the operation, the remaining of 50%endometrium was found in 1 case, the remaining of 30%endometrium was found in 1 case, and the remaining of 20%endometrium in 9 cases.Only petechial and patchy residual endometrial islands were found in 1 case.Uterine dysplasia was found in 3 cases.Re-examinations of hysteroscopy 3 months after surgery showed 4 cases of uterine cavity normal recovery , 6 cases of moderate intrauterine adhesions, and 2 cases of mild intrauterine adhesions .Follow-up for 18-42 months (mean, 28.5 months) in the 12 cases showed 2 cases of term pregnancy and 1 case of spontaneous abortion .The other 9 patients had no pregnancy , 3 of which withdrew the treatment and 6 of which underwent further treatment . Conclusions Patients with intrauterine re-adhesions usually have seriously damaged endometrium and poor recovery .We suggest that TCRA should be completed by experienced professionals to reduce the residual endometrial destruction , so as to improve the treatment outcomes of intrauterine adhesions .
