Objective To explore the influence of prenatal diagnosis,active follow up and immediate surgery intervention on the prognosis of congenital hydronephrosis in children.Methods The clinical data in 85 cases were analyzed retrospectively.They were divided into prenatal diagnosed group and postnatal diagnosed group.Prognostic parameters such as preoperative statuse,pathology during surgery,operation process,status before discharging and complications were collected and statistically analyzed.Results The numbers of grade 4 hydronephrosis,secondary renal calculus,opposite kidney hydronephrosis,preoperative infectioin,perinephric adhesion and postoperative complication in prenatal diagnosed group were significantly lower than those in postnatal diagnosed group(Pa0.05).Conclusions 1.Ultrasonagraphy examination and follow-up are indispensable both before and after delivery which will help doctors to diagnose the disease at early stage.2.Surgical operation on congenital hydronephrosis at early stage is reliable and will achieve the same effect with the children undergo surgical operation at older age.3.Immediate surgical operation is of great clinical significance on preventing serious complication and irreversible kidney damage.

The progression of liver fibrosis directly affects treatment options and prognosis.Early diagnosis and classification of liver fibrosis and dynamic monitoring are clinically needed.Noninvasive diagnostic techniques can avoid or reduce liver biopsy to enable early identifica-tion of liver fibrosis and to dynamically monitor the progression of fibrosis.But various limitations have restricted its application.Noninvasive diagnostic techniques,such as liver transient elastography using the different probe mode,controlled attenuation parameter,spleen stiffness measurement,ultrasound-based transient elastography for the early prediction of hepatic fibrosis,and risk assessment of hepatitis B virus-related hepatocellular carcinoma,have been applied in clinical studies.In order to better understand and apply these diagnostic models,the progress in clinical studies of noninvasive diagnosis of liver fibrosis,as well as the limitations,is reviewed.

Objective To prepare a 10-hydroxycamptothecin (10-HCPT) loaded folate-receptor targeted phase-change contrast agent (FR-HCPT-PNPCA),and to study the general characteristics including drug loading,phase changing and targeting capability in vitro.Methods Using a method of two-step emulsification,the phase-change nanoparticles loading anticancer drug (10-HCPT) with lipids shell and liquid pefluorocarbon core were prepared.The entrapment efficiency and the drug-loading amounts were studied by high performance liquid chromatography,and the phase transition of the nanoparticles after heating was observed.The targeting ability was evaluated on liver cancer cell line 7721 in vitro.Results The FR-HCPT-PNPCA,with a drug encapsulation rate of about 70.42 ％ and drug loading amounts of about 20.05 ％,was prepared successfully.When being heated to 70℃,obvious phase changing and microbubbles generating could be observed under microscope.In addition,a large amount of FR-HCPT-PNPCA particles could adhere specifically around the 7721 cells.Conclusion The prepared FR-HCPT-PNPCA,which has a stable characteristic and high performance of drug loading and tumor targeting,is expected to become a promising multifunctional molecular ultrasound probe for diagnosis and treatment of tumor.

Objective: To investigate the efficacy of gemcitabine in chemotherapy of cervical carcinoma. Methods:10 untreated cervical carcinoma patients had been divided into two groups,5 cases were treated with neoadjuvant chemotherapy and radiotherapy,others were treated only with radiotherapy. All patients were operated and compared the pathologic changes of cancers. Moreover 3 cases with recurrent tumors had been treated with gemcitabine and other agents . Results: The rate of complete response(CR) was 60% in group of neoadjuvant chemotherapy and 20% in patients with only radiotherapy. Only one case achieved partial response (PR) in patients with recurrence. Conclusion: The neoadjuvant chemotherapy in cervical carcinoma with gemcitabine is helpful for achieving good response .As radiation sensitizer or radio-potentiator,gemcitabine can promote efficacy of neoadjuvant chemotherapy in cervical carcinoma.

Objective: To study the factors relating the prognosis of ovarian granulosa cell tumor and the characteristics of its clinical presentations. Methods: The clinical records and pathological sections of 24 cases with granulosa cell tumor of ovary were reviewed retrospectively. The clinical characteristics, the clinical stage, and the therapeutic programs and the results were summarized respectively. Results:The 5-years survival rate showed that the clinical stage influenced the prognosis of ovarian granulosa cell tumor obviously. Conclusion: The early dection is the major factor which influences the patients' survival rate.

[Objective]To appraise the clinical effect of acupoint application on cough-asthma.[Method] Choose clinic 144 cases,measure FEV1,PEF and FEV1% after treatment,make statistical analysis,compare the difference of the appraisal indexes between before and after treatment,study the relation among age,sex and TCM syndromes.[Conclusion] After treatment,the symptoms score and lung function were markedly improved.[Conclusion] After treated with Dog-days Paste,the patients’ clinical symptoms were obviously relieved,and the lung functional indexes improved too.

[Objective]To filter and optimize extractive technology of Qianliening granules.[Methods]The optimization extractive technology of Qianliening granules was investigated using orthogonal design with the availability component extracting from the drug as the index.[Results]The optimal condition for the extraction of Radix Astragali group was 10 folds amount of water,3 times,1.5 hours each time.The optimal condition for the extraction of Rheum officinal Baill.group was 6 folds amount of 60% alcohol,2 times,two hours and 1.5 hours each time.[Conclusion]The optimized extractive technology is scientific and efficient.
