Objective To discuss the treatment of cervical cancer in different stages.Methods The treat- ment of 42 cases of cervical cancer in this hospital from January 2000 to December 2005 was analysed,and clinical treatment modalities were analysed too.Results(1)A total of 6 cases of uterine carcinoma in situ received hysterec- tomy plus bilateral salpingo-oophorectomy.(2)A total of 26 cases was inⅠb-Ⅱa stage,of which 15 cases with cer- vical cancer were treated with a simple radical hysterectomy;6 cases of cervical cancer were radiotherapied after radi- cal hysterectomy;7 cases of cervical cancer received radical hysterectomy plus radiotherapy.(3)A total of 10ⅡbⅣstage eases selected radiotherapy and chemotherapy.Conclusion Different treatment should be applied in differ- ent stages of cervical cancer,and the choice for treatment is important for patients' quality of life after treatment. Comprehensive treatment can improve the survival of patients with cervical carcinoma.

Objective To propose a new classification scheme of otitis media (OM). Methods By reviewing current internat ional classification systems of OM, we analyzed their disadvantages and the prog ress made in histopathologic studies of OM, then worked out a new classification scheme to apply it to clinic. Results In current internati onal classification systems of OM, those apparent clinical signs are regarded as main standards of classification. Their main disadvantage is that these signs c annot very well indicate the condition of pathologic and functional changes of i mportant hearing structure areas. We proposed a “Three-stage Scheme” of OM cl assification and applied in 1 160 cases of OM. The accuracy rate of diagnosis w as 82.4% in 348 cases of early-stage OM, 98.4% in 696 cases of chronic OM, and 95.2% in 116 cases of OM sequela. Conclusion The “Three-s tage Scheme” system is scientific, simple and practical. Its accuracy rate of d iagnosis is very high. It plays a guiding role in diagnosis and treatment of OM.

Cystatin C (Cys C) is used to evaluate the glomerular filtration rate (GFR), renal function and thus reflects changes in endogenous marker. Cys C is not affected by gender, muscle mass, malignancy and its production rate is usually constant, making it one of ideal markes of GFR. This article focuses on clinical application and research of Cys C in a variety of renal diseases, especially in renal dysfunction at an early stage of clinical significance.

ObjectiveTo evaluate the effects of selective cyclooxygenase-2 inhibitor nimesulide lone and combined with cisplatin on tumor growth,and Ki67 and Caspase-3 expression in lung cancer xenografts in nude mice. Methods The mice were randomly divided into 4 groups:the control group,the nimesulide group,the cisplatin group and the nimesulide combined with cisplatin group. A549 cells were injected into BALB/c nude mice subcutaneously.On the 21st day after treatment tumor tissues were collected,and the xenografts growth were observed. The expression of Ki67 and Caspase-3 were detected by immunohistochemical method.ResultsNimesulide combined with cisplatin could significantly inhibited the xenografts growth compared with nimesulide or cisplatin.The tumor inhibition rate was 44.33％ in the nimesulide group,53.61％ in the cisplatin group and 80.41％ in the nimesulide combined with cisplatin group (P ＜ 0.05).Immunohistochemical analysis showed that the expression rates of Caspase-3 was significantly increased in the nimesulide combined with cisplatin group (67.43 ± 23.57 ) ％,the cisplatin group (48.40 ± 20.37 ) ％,and the nimesulide group (38.65 ± 15.37)％,compared with the control group (27.63 ± 13.03)％ (P ＜ 0.05).The expression rate of Caspase-3 was significantly increased in the nimesulide combined with cisplatin group compared with the nimesulide group or the cisplatin group (P ＜ 0.05 ).The expression rate of Ki67 was significantly decreased in the nimesulide group combined with cisplatin group (24.34 ± 15.90)％,the cisplatin group (40.85 ± 22.47)％ and the nimesulide group (53.33 ± 19.67)％ compared with the control group ( 80.43 ± 16.88 ) ％ ( P ＜ 0.05 ).The expression of Ki67 was significantly decreased in the nimesulide combined with cisplatin group compared with the nimesulide group or the cisplatin group ( P ＜ 0.05 ).Conclusion Nimesulide can inhibit human lung cancer A549 cells xenografts in nude mice growth,Nimesulide enhanced the inhibitory effects of cisplatin.The mechanism may be related to inhibition of tumor cell Ki-67 expression,increased expression of Caspase-3,inhibition of tumor cell proliferation,and inducing tumor cell apoptosis.

Objective To explore the change of 25 hydroxyvitamin D level and its correlation with glucose metabolism and bone mineral density in elderly men with type 2 diabetes mellitus(T2DM).Methods Hospitalized 53 elderly male patients with T2DM (T2DM group) and 51 patients without T2DM (NDM group) were chosen.Blood.biochemical indexes and 25 hydroxyvitamin D level were measured.Bone mineral density of lumbar (L2_4),left proximal femur was measured by dual energy X-ray.Results The serum 25 hydroxyvitamin D level in T2DM group was lower than that in NDM group [(12.38 ±5.12)μg/L vs.(17.35 ± 5.52) μ g/L],and there was significant difference(P＜ 0.05).The serum 25 hydroxyvitamin D level was negatively associated with fasting blood glucose level and glycosylated hemoglobin (r =-0.225,-0.499,P ＜ 0.05).The serum 25 hydroxyvitamin D level was not associated with fasting insulin and homeostasis model insulin resistance index (r =-0.050,-0.082,P ＞ 0.05).The incidence of osteoporosis in T2DM group was higher than that in NDM group [30.19％(16/53) vs.11.76％(6/51)],and there was significant difference (P ＜0.05).The serum 25 hydroxyvitamin D level was positively associated with bone mineral density of femur neck,greater trochanter of femur and Ward triangle(r =0.773,0.762,0.812,P ＜ 0.05).The serum 25 hydroxyvitamin D level was not associated with bone mineral density of lumbar (L2_4)(r =0.116,P ＞ 0.05).Conclusions The prevalence of vitamin D deficiency is found in elderly men with T2DM.Vitamin D level can affect blood glucose control and increase the risk of the occurrence of osteoporosis.Therefore,T2DM patients,especially elderly patients,should be routine vitamin D testing.Vitamin D supplementation to the patients of vitamin D insufficiency in time may be beneficial to glucose metabohsm and the prevention and treatment of osteoporosis.

Objective To explore the posibility of removing the jugular tubercle precisely and design a new far-lateral supraeondylar keyhole approach based on keyhole idea.Methods Eight cadaveric heads fixed by 10% formalin and perfused intracranial vessels with colored silicone were used in this study.Before the operation,navigation data of these cadaveric heads were established and circumscriptions of jugular tuber- cle were outlined in the navigation system in order to aid drilling it in operation.A 7cm longitudinal“S”shaped skin incision as we reported was performed.After inverting suboccipital muscles and exposing the far lateral of the occipital bone,occipital condyle,jugular tubercle,hemilamina of C_1,vertebral artery and pos- terolateral portion of foramen magnum,a 3cm retro-condylar bone window was made.Under the microscope, anatomic structures were observed and important structures were measured after jugular tubercle removal assis- ted by neuro-navigation.Results The 7cm longitudinal“S”shaped skin incision with its superior border 2cm behind the middle point of mastoid and inferior margin at the level of C_2 can fully meet the needs of the far-lateral supracondylar keyhole approach;jugular tubercle can be drilled satisfactorily with the help of neuro- navigation;inferior segment of basilar artery[long(15.65?1.34)mm]and anterior inferior cerebellar artery [long(20.36?4.18)mm] can be exposed.Conchlsion Owing to the area of middle clivus is increasingly exposed after removal of jugular tubercle,it is feasible to perform the far-lateral supracondylar keyhole ap- proach on the operations of vertebral-basilar artery aneurysm,anterior inferior cerebellar artery aneurysm and tumor located inferior and middle clivi or jugular foramen.

AIM: To study the clinical effects of using sodium hyaluronate in the glaucoma trabeculectomy. ·METHODS: Totally 46 patients were included in our research and they were divided into two groups. In the study group (23 cases 23 eyes), we used slice with MMC of 0. 4mg/mL in trabeculectomy. Before the conjunctiva flap was sewed, a small amount of sodium hyaluronate was injected into the space under scleral flap and the anterior chamber. In control group ( 23 cases 23 eyes ) , we only used MMC. After trabeculetomy, shallow anterior chambe formation, intraocular pressure, corneal endothelial injury and the formation of filter-bubble were observed in long term. ·RESULTS:IOP of study group at 1d after operation was higher than that of control group ( P<0. 05 ), but not significant different at 3d, 1 and 6mo after operation(P>0. 05). At 3d after operation, visual acuity decreased in 2 eyes (9%) of study group, 8 eyes (35%) in control group with significant different ( P = 0. 035 ). At 6mo after operation, visual acuity decreased in 0 of study group, 5 eyes (22%) in control group with significant different (P=0. 025 ). The differences on the occurrence of shallow anterior chamber at 7d after operation, formation of filter-bubble at 6mo after operation and corneal endothelial count were significant (P<0. 05). There were less postoperative complications in study group than in control group. ·CONCLUSION: Using sodium hyaluronate combined with MMC in trabeculectomy can greatly prevent the formation of shallow anterior chamber, filter-bubble scarring, and corneal endothelium dropout, make it possible to a safer surgery and a better outcome.

Objective To explore the bio-effects of high single-dose irradiation on MDA-MB-231 xenografts under the same radiation dose.Method Female BALB/c-nu mice bearing 8-9 mm MDA-MB-231 xenografts were randomized into 5 groups:0Gy group (blank control group),high single-dose 8Gy group (8Gy/one fraction/day),high single-dose 10Gy group (10Gy/one fraction/ day),conventional radiation 2Gy × 4 group (8Gy/4 fraction/4d),conventional radiation 2Gy × 5 group (10Gy/5 fraction/5d).The volumes of gross tumors on nude mice were observed every three days.The tumor growth curve of transplanted tumor were also drawn.The 18F -FDG PET/CT imaging of mice bearing MDA-MB-231 xenografts from all radiation groups were performed with detecting the Ki-67 expressions of tumor ceils by immunohistochemistry at 7days and 14days after final irradiation.Results Compared to control group,the tumor growth of all radiation groups were delayed after radiation,especially single high-dose 10Gy groups (P ＜ 0.05).At 7days and 14days after final radiation,the SUVmax (the maximal standardized uptake value) of xenografts in high single-dose groups was lower than that in conventional fractional groups (P ＜ 0.05) under the same radiation dose.And the percent of Ki-67 positive cells after high single-dose irradiation were less than fractioned irradiation at 7,14days after final radiation (P ＜ 0.05).Conclusion At the same dose,high single-dose irradiation inhibits the growth of MDA-MB-231 xenografts more than conventional fraction irradiation.PET/CT also could evaluated the early changes of proliferation activities of MDA-MB-231 breast cancer cells after irradiation.

Angiogenesis is vital in the process of primary tumor growth,proliferation and metastasis.In many cancers,including non-small cell lung cancer (NSCLC),inhibition of tumor angiogenesis has been identified as an important therapy.The most common drugs include bevacizumab,ramucirumab,tyrosine kinase inhibitor such as sorafenib tosylate,and nintedanib.We will summarize the research about some inhibition of tumor angiogenesis.

Aim To explore the expression of CD1a＋ DC in fair follicle of normal human skin and psoriasis patients. Methods Expressions of CD1a＋ DC in 10 fair follicles of psoriasis patients and skins of 8 normal human were detected by SABC immunohistochemical staining. Results The numbers of CD1a＋ DC in upper limb skin and scalps's fair follicle were 13 and 15 respectively. The number of CD1a＋ DC in fair follicle of psoriasis patients was 16,slightly more than that in skins. There was obviously higher density of CD1a＋ DC in psoriasis fair follicle and its number was 46± 15/mm2. Conclusion The area of fair follicle is connected with the start and redistribution of CD1a＋ DC,and the fair follicle may have important effect on development of vulgaris psoriasis.
