??OBJECTIVE To evaluate the effects of hormone replacement therapy(HRT) on the quality of life in climacteric women.METHODS The 202 patients were collected and divided into three groups according to whether or not they were treated with HRT: group 1 (not HRT), group 2 (HRT for the first time), group 3 (HRT for more than one year). All patients received follow-up visiting once per three months for one year. They were evaluated by the professionals through Kupperman index(KI), menopause-specific quality of life questionnaire(MENQOL), self-rating anxiety scale(SAS), self-rating depression scale(SDS). All patients were guided to improve the way of life.RESULTS After a year, KI, MENQOL and SAS in the three groups were improved significantly (P=0.003, 0.007, 0.014). KI and MENQOL were improved earlier than SAS. SDS was improved but not significantly(P=0.109). KI, MENQOL, SAS and SDS of patients in group 1 were improved significantly, but improved more weakly than those in group 2 and group 3. There is negative correlation between HRT and the values of every scale, and there is positive correlation between culture degree and SAS, SDS score values. CONCLUSION HRT canim prove the quality of life in climacteric women. The improvement in physical symptoms is earlier than that in mental symptoms. Anxiety and depression are more likely to occur in menopausal patients with high degree of education. Traditional Chinese medicine, exercise therapy and physical rehabilitation can be used as an auxiliary treatment for patients who are unable or unwilling to accept the HRT. 相似文献

??OBJECTIVE To analyze the regularity, clinical reactions and outcomes of the adverse reaction of sorafenib to provide reference for safe medication in clinical practice. METHODS The case reports of sorafenib ADR which were published at international medical academic periodicals during 2006-2016 were collected and analyzed statistically in respect of gender, age, disease informations, clinical manifestation and RESULTS of treatment. RESULTS A total of 93 adverse reactions were identified and included in the analysis, 22 cases were unexpected ADR. The ADR happened in male was more than in female, and the age of 61-80 was the most common population (45.16%). The ADR was mostly happened in 1 month (71.11%) after therapy. Lesions of skin and its appendants were the most commonly reported ADRs (51.52%), followed by the lesions of digestive system (22.73%) ,which reported the most of the death cases (n=19 , 6 death). The ADR correlation rate was high in these case reports. CONCLUSION Multiple organ systems are involved in the ADRs of sorafenib, amd careful clinical observation and symptomatic treatment in time are necessary. 相似文献

??OBJECTIVE To prepare the total alkaloids of Strychni Semen(TASS)-total glucosides of Paeony(TGP) gel and study its in vitro transdermal absorption of two alkaloids(strychnine and brucine) after the combination of TASS and TGP. METHODS The excised abdominal skin of mice was used as the permeation model. Utilizing the modified Franz diffusion cell, the suitable receiving solution was elected to test the content of two alkaloids by HPLC, and thus the percutaneous rates and permeability coefficients were obtained. RESULTS 20% Ethanol-normal saline was taken as receiving solution. With combination use of TASS and TGP, the penetration quantities of strychnine and brucine in different (1:1,1:3,1:6) gels were felled by 22.7%,48.4%,69.1% and 5.93%,23.8%,80.7% after 24 h. And with the increase of compatibility proportion, infiltration rate and skin retention rate also gradually reduced. CONCLUSION The compatibility of TASS and TGP drug delivery can reduce the toxic ingredients through capacity, there is a “attenuated” effect, the best ratio is 1:6. 相似文献

??OBJECTIVE To examine the in vitro release profile and in vivo retention of estradiol vaginal thermosensitive gel (E2-VTG).METHODS E2-VTISG was prepared by cold dissolving method.The dynamic membrane dialysis method and HPLC-fluorometric method were used to determine the in vitro release characteristic of the estradiol vaginal thermosensitive gel.CRi Maestro was applied to evaluate the retention of E2-VTG in ICR mice with IR820 as the fluorescent marker. RESULTS Estradiol could be released slowly from the thermosensitive gel and the release profile was fitted with Higuchi equation. It was speculated that estradiol was mainly released through diffusion.NIR imaging and fluorescence quantitative analysis showed that thermosensitive gel could reside in vagina for at least 8 h. CONCLUSION Estradiol thermosensitive gel can prolong the drug residence time in vagina and sustain the drug release rate. 相似文献

??OBJECTIVE To establish dose-related lung inflammatory injury in rats model with intratracheal atomization of lipopolysaccharide (lipopolysaccharides, LPS). METHODS Four groups of 4 rats were subjected to solvent or a single dose of LPS by intratracheal route using a IA-1B-2 inches-microsprayer. The male rats received 200 ??L solvent (control), LPS solutions (15, 5, 0.5 mg??kg-1). All rats were sacrificed 24 h after dose administration, biochemical analysis and cell counts on bronchoalveolar lavage fluid (BALF) were performed on each rat. Lung, trachea and kidney were examined histologically. Serum chemistry profiles of creatinine, ALB, Na, K, Cl- were detected. RESULTS Cell counts in BALF showed LPS groups had different degrees of inflammatory reaction. The alkaline phosphatase and total protein concentration were higher in LPS high dose group compared with other groups. In addition, the concentration of TNF-?? increased consistently with LPS dose and has statistical significance compared with the control group. Histopathology findings demonstrated that LPS produced an accumulation of foamy macrophages in the lungs and high degree of inflammation. CONCLUSION The results recommends intratracheally atomizing doses of LPS in rats model produced ranks of lung inflammatory injury. 相似文献

??To improve the in vitro dissolution and in vivo absorption as well as the bioavailability after oral administration by increasing the solubility with the formation of solid dispersion remains a great challenge for the oral dosage form design of poorly water-soluble drugs. Compared with the other pharmaceutical techniques in improving the solubility for poorly water-soluble drugs, priorities are usually given to solid dispersion for its manufacturing convenience. Following the characteristics introduction, we were focused this review on the novel carriers and advanced techniques used for preparing solid dispersions. Amphiphilic polymers used as novel solid dispersion carriers are Solutol HS 15, Soluplus and poly [MPC-co-BMA]. Inorganic materials like magnesium aluminum metasilicat, mesoporous silica microparticle and mesoporous magnesium carbonate are introduced together with the advanced solid dispersing techniques such as supercritical fluid technology, high speed electro-spinning and microenvironmental pH modified technology. 相似文献

??OBJECTIVE To develop a rapid DNA detection kit for DNA extraction and PCR identification of Panax ginseng C.A. Mey. METHODS The classical DNA extraction and PCR identification METHODS for Panax ginseng C.A. Mey were modified, and the compositions and reaction conditions of the kit were determined. In addition, the specificity, stability, sensitivity, and repeatability of the kit were evaluated. The genomic DNAs of genuine and counterfeit ginseng goods were extracted by the kit and PCR was performed to identify the authenticity. The purity of the extracted DNA was detected by UV spectrophotometry. Finally, commercially available ginseng samples were verified. RESULTS The purity of the genomic DNA extracted by the kit was (1.73??0.13)(OD260/ OD280), and a fragment between 150 and 200 bp could be amplified only from authentic Panax ginseng C.A. Mey. The specificity of the kit was 100%. The repetitive experiments showed that the average intra-assay CV% and inter-assay CV% of the kit were 2.38% and 2.62%, respectively. The DNA in solutions diluted by 200 times could still be detected. Stability experiment proved that repeated freeze-thawing for 20 times had no significant effect on the activity of this kit and the test sample could be stored at -20 ?? for one year. The specificity test confirmed that 8 samples among the 10 commercial products were genuine, and 2 were counterfeit. CONCLUSION The nucleic acid extraction and purity of the DNA detection kit can meet the requirement for identification of Panax ginseng C.A. Mey.The kit has good specificity, high sensitivity, and good stability, so it is suitable for the rapid detection of Panax ginseng C.A. Mey. 相似文献
