ObjectiveTo explore the clinical effect and safety evaluation of marvelon on dysfunctional uterine bleeding in adolescent patients.Methods120 adolescent patients with dysfunctional uterine bleeding were randomly divided into control group and experience group with 60 patients in each group.Control group was given oral administration of premarin and experience group received marvelon oral treatment.Clinical effect,the time of control bleeding and completely stop bleeding and incidence of adverse reaction were compared between two groups.ResultsThe total effective rate in experience group was much higher than that in control group (100.0％ vs 90.0％,x2 =6.316,P ＜ 0.01 ) ;The time of control bleeding and completely stop bleeding in experience group were much lower than that in control group( t =6.638,8.542,all P ＜ 0.01 );The incidence of adverse reaction in experience group and control group were 11.7％ and 65.0％ respectively with significant difference( x2 =36.099,all P ＜0.01 ).ConclusionMarvelon on dysfunctional uterine bleeding in adolescent patients is beneficial to rapid and effective hemostasis with less adverse reaction rate and better tolerance.

Objective To investigate the cost-effectiveness of four drugs in treatment of bacterial vaginitis and improve clinic rational drug use.Methods 361 bacterial vaginitis out-patients were treated with lactobacillus vaginal effervescent tablets(92 cases),lacidophilin vaginal capsules(88 cases),shuangzuotai vaginal effervescent tablets(90 cases),metronidazole vaginal effervescent tablets(91 cases).The therapeutic effect,drug cost and therapeutic effect were evaluated by cost effectiveness analysis 7d after treatment.Results The overall response rate of lactobacillus vaginal effervescent tablets,lacidophilin vaginal capsules,shuangzuotai vaginal effervescent tablets,metronidazole vaginal effervescent tablets were 78.26％,76.14％,83.33％ and 78.02％,respectively.The overall response rate was no significant difference between four groups (0.06),and metronidazole vaginal effervescent tablets had the lowest cost effectiveness rate (C/E,0.26).Conclusion The metronidazole vaginal effervescent tablets is better schedule in treatment of bacterial vaginitis.

As more attention is given to people's life and health,China continues to increase investment in scientific research to improve the level of medical research. However,the efficiency of the investment is unknown.In this study,we used the method of data envelopment analysis (DEA) to investigate the input-output relative efficiency of the projects funded by National Natural Science Foundation of China and completed in 2009 at 17 research institutes.We found 11 institutes to be DEA efficient,and 6 to be inefficient.It also showed that adjustment of research structure and setting performance objectives may improve the level of research management and increase the efficency of the investment.

Objective: To investigate the effect of GLP1 on the blood glucose in type 2 diabetic rats,and its protective effects on the islet B cells.Methods: Thirty rats were divided into three groups: spontaneous type 2 diabetes animal model OLETF rats,GLP-1 [from the twelfth week 56 ?g/(kg?d),sc] therapy group and LETO rats as control.In the 14th and 20th weeks,standard OGTT including fast and 2 h-plasma glucose were measured respectively.In the 14th weeks,3 rats from each group were killed randomly,and the rest of the rats were killed until the 20th week.Immunostaining with the marker of PCNA,TUNEL,and insulin assessed metabolic changes in the islet. Ultrastructure of the B cell was observed with the electronic microscope.Results: In the 14th and 20th week,AUC for insulin were higher in treated animals(10.86?1.56 vs.9.07?1.28,P

Objective To probe into the methods of postoperative nursing care for the patient undergoing domino liver transplantation.Methods The key of postoperative care included:monitoring of vital signs,the condition of cruor and the state of drainage rigorously; keeping the balance of intake and output; taking the immunosuppressive drugs correctly; proper diet; prevention of complication;giving psychological nursing.Results The patients passed the perioperative period successfully and were all cured.Conclusions To aim at the characteristic of this operation,implement holistic nursing care,is an important link to assure the patients of domino liver transplantation to recover smoothly after the operation.

Objective To explore the effect of docosahexaenoic acid(DHA)on the neuro-logical outcome as well as the expression of interleukin-1β,interleukin-6 and interleukin-10 after acute spinal cord injury(SCI).Methods One hundred and eight Sprague-Dawley rats were randomly divided into a spinal cord injury group(group A),a DHA treatment group(group B)and a sham operation group(group C),each with 36 rats.SCI models were established in the rats of groups A and B using a version of Allen's weight drop method(T10 level).Group C had removal of the lamina only.Ten minutes later,group A was injected with 5% ethanol in saline(the MT solvent)and group B with 500 mg/kg of DHA preparation.Basso beattie bresnahan locomotor rating scale(BBB)was used to detect locomotors function at 10,24,48 and 72 hours after operation.Rats were sacrificed at 72 h after operation,IL-1β,IL-6 and IL-10 levels in serum were detected in 6 rats of each group.Results BBB locomotor rating scale indicated that hindlimb motor function in Groups B was higher than that in Group A at 10,24,48 and 72 hours after operation.There was a significant difference in locomotor rating score between DHA injection group and control group(P<0.05).The specimens of group A showed inflammatory reaction and ulceration at 72 h:Group C showed the highest levels of IL-10 in serum ,while Group A showed the lowest level.The differences were statistically significant.Group A had the highest levels of IL-1β and IL-6 while group C had the lowest.The difference between group B and groups A and C was significant.Conclusion DHA could play protective role by balancing the reconstruction of the anti-inflammatory response and inflammation in rats with acute spinal cord injury.

Gastric cancer is a kind of disease with high incidence and mortality rate,most gastric cancer cases are diagnosed in an advanced,and chemotherapy is the main treatment.Drug resistance is one of the most important causes of therapy failure in gastric cancer patients.It has revealed that the mechanism of tumor resistance mainly involves alterations in cell cycle and proliferation,enhanced DNA repair capacity,defective apoptosis,damaged host immune,altered metabolism of drugs and so on.In recent years,an important molecule-microRNA(miRNA)that regulates the biological behavior of cell has attracted more and more attention.Studies have confirmed that numerous miRNAs can regulate the drug resistance of gastric cancer cells via BCL-2 signaling pathway,PTEN/PI3K/AKT pathway,ABCB1(MDR1/P-gp),autophagy,cell cycle and so on.

The diagnostic criteria of diabetes has been changed several times in the latest thirty years.The diagnostic criteria is based on plenty of epidemic studies,especially the relationship between the glucose level and the microvascular complications.However,there are many problems in the clinical practice of using the recent diagnostic criteria(1999 WHO criteria).Glycosylated hemoglobin(HbA1c) has been recommended as a diagnostic criteria in the 69th ADA.

Analysis of metabolic activities of cytochrome P450 isoenzyme is a crucial index to study drug/toxicant metabolism, drug-drug interaction, polymorphism and et al. Due to this practice, it is important to use the proper probe substrate and to conduct the experiment under optimal conditions. The validation information in literatures on the most common and newest in vitro probe substrates have been reviewed.

Immunohistological methods were used to investigate the presence of s-100 protein in 16 cases of malignant mesothelioma (MM) and 20 metastatic gastrointestinal adenocarcinoma of peritoneum. Positive staining for s-100 protein was observed in 14 of 16 MM, while it was negative in all metastatic gastrointestinal adenocarcinoma of peritoneum. Since antibodies to s-100 protein are readily available as standardised commercial products, the combined immunolocalisalion of s-100 protein should prove to be an efficient routine means of differentiating MM from difficult cases of metastatic gastrointestinal adenocarcinoma of peritoneum, in both necropsy and surgical cases.
