Objective To investigate the diagnostic value and clinical implications of low hemoglobin density(LHD%)in the pa-tients with cervical carcinoma complicating iron deficiency anemia(IDA).Methods The iron metabolism indexes and whole blood cell parameters were detected in 148 patients with cervical carcinomas.LHD% was calculated.The results were compared with that in the healthy group and the hysteromyoma complicating IDA group.Results LHD% was(63 ±30)% in the cervical carcinoma complicating IDA group and(32±15)% in the cervical carcinoma complicating iron deficient erythropoiesis(IDE)group,which were higher than(7±6)% in the healthy group,(22 ±21)% in the cervical carcinoma non-iron deficiency group and(16 ±10)% in the cervical carcinoma non-anemia group(P <0.05 ).And which had no statistical difference between the hysteromyoma complicating IDA group and the cervical carcinoma complicating IDA group(P >0.05 ).Conclusion The new RBC parameter LHD% has the reference value in the diagnosis of cervical carcinoma complicating IDA.The LHD% increase may prompt cervical carcinoma com-plicating IDA.

A 35-year-old woman patient,complained of intermittent pain in the left flank for a week.Abdominal ultrasound and computed tomography scan revealed a left renal mass.Nephrectomy was performed,and a final diagnosis of adult Wilms' tumor was made based on histopathology and immunohistology.Chemotherapy was conducted for 4 times with dactinomycin D,vincristine and doxorubicin after surgery.At the time of the last recheck,the patient was alive with no evidence of disease.Adult Wilms' tumor is the exceptional malignant renal tumor.Only 1%-2% of Wilms' tumor is diagnosed in adult patients.Because of unspecific tumor symptoms in adults,the diagnosis is frequently made by histology.The diagnosis of adult Wilms' tumor is difficult to make preoperatively because diagnostic imaging only confirms the presence of a renal mass.Stage and histology are the clinical factors guiding the selection of postsurgical treatment and prognosis.Having retrospected 6 cases of adult Wilms' tumor between 1950 and 2007 and reviewed related reports,we conclude that the proper strategies of adjuvant treatment as applied to childhood Wilms' tumor patients after surgery can conspicuously improve the outcome in adult patients.

Objective To analyze the characteristics of military training injury caused by distal femoral fractures that used reverse interlocking intramedullary nail(retrograte nails) and condylar plate to fix,and then compare the clinical treatment effects.Methods Retrospective analysis of clinical information of 30 cases,14 cases were treated with reverse interlocking intramedullary nail(reverse nail group) and 16 cases with condyle plate fixation(condyle plate group),all the cases were followed up for 12～20 months to compare the treatment effect and complications.Results According to Merchan criteria with clinical evaluation of knee function,the rate of good and excellent was 85.7% in the reverse interlocking in-tramedullary nail group,68.7%(P

The latest progress of modern radiotherapy techniques in the management of breast cancer after breast-conserving surgery was introduced first.Then the clinical effect and the adverse effect of these advanced techniques were analyzed.Finally,in order to provide an up-to-date evidence based data on the role of modern radiotherapy techniques in the management of breast cancer,the importance of how to choose appropriate patients for these advanced techniques was discussed.

Objective To investigate the effects of peroral catheter balloon dilatation on patients with dysphagia caused by cricopharyngeal achalasia after stroke.Methods Thirty-two stroke survivors with cricopharyngeal achalasia were randomly divided into a control group and a treatment group,each of 16.Both groups were given routine dysphagia rehabilitation training,but the treatment group was additionally given peroral balloon dilatation therapy six times a week for 2 weeks.Both groups were given swallowing function evaluations and videofluoroscopic swallowing examinations (VFSS) before and after the treatment.Results After the treatment,14 of the 16 patients in the treatment group demonstrated improved swallowing,significantly better than the control group,where only 9 patients had improved.The VFSS showed dysphagia to have been relieved in both groups,but significantly more in the treatment group.Transit duration in the pharnx was significantly shortened from 0.28 s to 0.16 s in the treatment group,but no significant difference was tound in the control group.Conclusion Peroral catheter balloon dilatation is effective for relieving cricopharyngeal achalasia after stroke.

Objective:To coat sirolimus ( SRL) dropping pills with a membrane to enhance the ability of moisture proof. Meth-ods:Opadry was chosen as the coating material. The solvent, concentration and weight gain of the coating membrane were defined, and the coating parameters were screened. The critical relative humidity ( CRH%) of membrane-coating SRL dropping pills was detec-ted and compared with that of SRL dropping pills without coating. Results: The formula and coating parameters of membrane-coating SRL dropping pills were as follows:95% ethanol was used as the solvent, Opadry concentration was 6. 5%, the weigh gain was 4%, the inlet air temperature was (35 ± 2)℃, the inlet fluid rate was 12 ml·min-1 and the spraying pressure was 3. 0 MPa. The CRH%of memebrane-coating SRLs dropping pills was 63. 1%, which was much higher than that of uncoated SRL dropping pills (36. 1%). Conclusion:The membrane-coating can enhance the moisture proof of SRL dropping pills, which is beneficial to the stability.

Objective:To prepare sirolimus ( SRL) dropping pills to improve SRL solubility and dissolution. Methods:The base of SRL dropping pills was screened. The optimal formula and preparation process were also optimized by orthogonal design. The equi-librium solubility, hygroscopicity and drug release in vitro of SRL dropping pills were studied. Results: PEG6000 was chosen as the base. The optimal preparation conditions of SRL dropping pills were as follows: the ratio of SRL and base was 1∶10, the dropping speed was 65 drops/min, the dropping temperature was 95℃ and the temperature of cooling solvent was 5℃. The equilibrium solubili-ty of SRL dropping pills in different solvents was increased significantly compared with that of SRL. The hygroscopicity of the dropping pills was notable. The drug release in vitro of SRL dropping pills was similar to that of the marketed tablets with quick and complete re-lease. Conclusion:SRL dropping pills exhibit increased solubility and improved dissolution, which are valuable to be studied further.

OBJECTIVE: To investigate the effect of trichostatin A (TSA),a specific inhibitor of histone acetyltransferase,on apoptosis of human hepotoma cell line HepG2,the expression of fragile histidine triad (FHIT) and apoptosis-related proteins in order to study apoptosis mechanisms.METHODS: Human hepatoma cell lines HepG2 were cultured and treated with different concentrations of TSA(125,250,500,1 000,2 000 nmol?L-1) for 24 and 48 hours.Human hepatoma cell lines HepG2 survival and apoptosis were determined by MTT assay with absorbance vale and inhibitory rate as index.Apoptotic percentage of HepG2 treated with 250 and 1 000 nmol?L-1 TSA were determined using TUNEL assay.The expressions of FHIT and caspase-3,bax,bcl-2 were analyzed by immunocytochemistry with solvent as control.RESULTS: As compared with control group,absorbance vale of human hepatoma cell lines HepG2 were decreased after treated with different concentration of TSA in dose-dependent and time-dependent manners.Positive cell rate in TUNEL was increased (P0.05).CONCLUSION: TSA may inhibit proliferation and promote apoptosis of hepatoma HepG2 cell by up-regulating the protein expression of FHIT,caspase-3 and bax.

Objective To evaluate the relationship between the expression of cyclooxygenase-2(Cox-2) and inducible nitric oxide synthase (iNOS) and the angiogenesis in gastric carcinoma. Methods Immunohistochemical stain was used to detect the expression of Cox-2, iNOS and MVD in 45 resected specimens of gastric carcinoma. The monoclonal antibody against CD34 was used for displaying vascular endothelial cells, and MVD was detected by counting the CD34-positive vascular endothelia cells. Paracancerous tissues were examined as the control. Results The expression rates of Cox-2, iNOS and MVD in gastric cancer were significantly increased, compared with those in the paracancerous tissues (77.78% vs. 33.33%, 68.89% vs. 17.78%, 58.13?19.99 vs. 24.02?10.28, P
