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.

Selective COX-2 inhibitors can promote the apoptosis of tumor cells and block the growth of new blood vessels through the inhibition of ring oxidase,vascular endothelial growth factor,microvessel and so on. Research shows that COX-2 is overexpressed in vascular and endothelial cells of lung cancer,select COX-2 inhibitors to adjuvant chemotherapy,not only can directly inhibit the tumor proliferation,but also can reduce the adverse reaction of chemotherapy drugs,and enhance the curative effect. To investigate the effects of selec-tive COX-2 inhibitors and cisplatin in lung cancer angiogenesis and its mechanism,will be a hope for the clini-cal treatment of tumor.

COX-2 is the inducible form of cyclooxygenase,which is overexpressed in non-small cell lung cancer,especially in the adenocarcinoma,and is involved in the production of lung cancer drug resistance, reducing the sensitivities of tumor cells to chemotherapy drugs. COX-2 inhibitors have the effects of antitumor and prevention of tumor formation. Therefore,in order to reverse the drug resistance of tumor cells,improve the sur-vival rate and the prognosis of patients with tumor,the application of COX-2 inhibitors as adjuvant chemotherapy and combined with chemotherapy drugs has become a new direction in the treatment of lung cancer.

Objective To evaluate the clinical value of dual-energy subtraction digital radiography in diagnosing the pulmonary nodulesand calification in nodules.Methods Using American GE Revolutln DR-XR systems,All 80 patients were examined by dual-energy.Tissus images、bone images and the original digital radiographic images were obtained.Dual-energy digital subtraction images were compared with the original digital radiographic images.Results Of 186 pulmonary nodules proved by CT,126(94 uncalified and 32 calified)were detected by tissues images and bone images and 109(83 uncalified and 26 calified)were detected by the original digital radiographic images.Conclusion Dual-energy subtraction imaging is superior to the original digital radiographic images in detection of pulmonary nodules and calification in a nodule.Dual-energy subtraction images can act as a complement for the original digital radiographic images.

The monosialic acid ganglioside GM1 is rich in brain, which participates in the development process of the nerve system and plays wide neuroprotective roles. This article reviews recent reports about six neuroprotective mechanisms including: activating tyrosine kinase receptor——Trk receptor, modulating Ca 2+ homeostasis in cells, reducing the deposition of A? and its toxic roles in brain, inhibiting the production of reactive oxygen species, enhancing the activity of Na+,K+-ATPase.

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.

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.

Objective To analyze the demand for home care service and its influential factors among elderly in Tianjin city.Methods A total of 254 residents aged 60 and above from Tianjin city were investigated with a self-designed questionnaireDemand for Home Care Service,Katz index of independence in Activities of Daily Living(ADL) and Lawton Instrumental Activities of Daily Living (IADL) scale.Results The mean score for home care service has been revealed (2.40±0.67),as the ranking demonstrated:public welfare (3.61±1.04),social participation (2.69±1.32),medical service (2.56±0.90),rights safeguard by law (2.37±1.54),mental need (2.26±0.99),and need for daily life care (1.73±0.69).Multiple linear regression analysis showed that income,education level,activity of daily living and the convenience degree of seeking treatment were major factors affecting demand for home care service among elderly,which explained 16.3％ of the variance.Conclusions Oriented by demand,further progress shall be achieved multidimensionally,under which circumstances,individualized service ought to be de-livered.Simultaneously,the vulnerable elderly groups require more attention.

OBJECTIVE: To investigate the pathogenic factors of severe acute pancreatitis (SAP) complicated by hepatic insufficiency, the prognosis and the effective preventive and therapeutic interventions. METHODS: One hundred and fifty-two patients with SAP (from January 2003 to June 2004) were divided into 2 groups, SAP with hepatic insufficiency group and SAP without hepatic insufficiency group. The related factors such as causes of disease, serum biochemical criteria, complications, mortality and course of disease were observed. RESULTS: The concentrations of serum amylase, creatinine and lactate dehydrogenase were all much higher in the SAP with hepatic insufficiency group than those in the SAP without hepatic insufficiency group (P<0.05). The incidences of complications such as acute renal failure, heart failure, gastrointestinal hemorrhage and infection were also higher in the SAP with hepatic insufficiency group than those in the SAP without hepatic insufficiency group (P<0.05). There was no significant difference in mortality between these two groups, but the course of disease in SAP with hepatic insufficiency group was longer than that in the other group (P<0.05). CONCLUSION: The causes of SAP complicated by hepatic insufficiency are related to the imbalance of internal environment and the characteristics of the liver function. To control the biliary tract diseases, intervene with traditional Chinese medicine, recover the intestinal function in time, reduce the damage of pancreatic enzyme, maintain the stability of internal environment and avoid using drugs that can induce liver injury are all important aspects of reducing the incidence of hepatic insufficiency.
