Objective:To get the basic situation of the list of low-price medicines and their sales in Tianjin to pro-vide future policy reference. Methods:The low-price medicine list was analyzed through different principles of classifica-tion including the National Essential medicine List ( NEML) , National Reimbursement medicine List ( NRML) and exclu-sive production. The study analyzed the sales status of the low-price medicines in the Tianjin from 2008 to 2011 using the Tianjin Urban Employee Basic Medical Insurance (UEBMI) database. Results:19 classes of chemical medicines and eight classes of traditional Chinese Medicine are included in the low-price medicine list. All of the medicines in the low-price list come from the NRML, and the replication ratio between the NEML and the low-price medicine list is 54. 1%. There are 41 exclusive productions and 149 exclusive formulation productions. From 2008 to 2011, the average ratio of the chemi-cal low-price medicines and traditional Chinese Medicine sales to total medicines sales are 4. 7% and 11. 0%, respective-ly. Both national essential medicines and exclusive formulation production sales ratios are increasing, however the sales ra-tio of exclusive production decreased from 2008 to 2011. Conclusion:The government should pay greater attention to the supply and production of the list’s exclusive production. The sales ratio of low-price medicines to total medicines sales is much lower in the retail pharmacies and tertiary medical institutions than other medical institutions. Suggestions:The gov-ernment should practice the shortage report system of common low-price medicine as soon as possible, with efforts made to implement the global budgeting policy and encourage sales enthusiasm for low-price medicines in retail pharmacies.

Objective To estimate direct economic burden of patients with moderate to severe psoriasis in China,and to assess its influencing factors.Methods A questionnaire survey was carried out in 150 patients with moderate to severe psoriasis from 29 third-grade class-A hospitals in 7 cities.Data on demographic characteristics,clinical features and direct economic burden were collected.Descriptive statistics were performed to analyze the direct economic burden of moderate to severe psoriasis,and multiple regression analysis was carried out to determine predictors of cost of illness.Results The patients were aged (43.87 ± 13.42) years,with an average clinical course of 3 years(range,2-6 years).Of them,82 had moderate psoriasis,and 68 had severe psoriasis.The average direct cost was (6 452 ± 6 391)RMB per patient-year,with significant difference between the patients with moderate psoriasis and those with severe psoriasis ((4 163 ± 4 605) vs.(9 212 ± 7 146) RMB,z =5.70,P ＜ 0.001).Regression analysis indicated that disease severity,clinical type,hospitalization,complications,and inhabited cities were factors influencing the direct economic burden of patients with moderate to severe psoriasis.Conclusions The direct eonomic burden of severe psoriasis seems to be twice that of moderate psoriasis in China.Physicians should strengthen the control of complications and disease severity,and pay more attention to other types of psoriasis than psoriasis vulgaris,during the treatment of psoriasis.

Objective To evaluate the effects of celecoxib on tumor growth,COX-2 and survivin expressions and angiogenesis in nude mice. Methods Xenograft animal model was established by injecting human colon cancer HT-29 cells into the BALB/c nude mice subcutaneously. Fifty mice were randomly divided into 4 groups 16 d after injection:control group,celecoxib group(receiving 25,50,75,100 mg?kg-1?d-1 for 35 d). Tumor volumes were measured every week. The expression level of COX-2,survivin and the microvessel density (MVD) of the xenograft tumor tissues were measured by immunohistochemistry,and mRNA level of VEGF by RT-PCR. Results Celecoxib at dose of 25,50,75 and 100 mg?kg-1?d-1 inhibited the tumor volume by 34.94%,39.20%,53.50%,59.20% respectively,and showed more effective in suppressing the tumor growth than the control group(P

This study is to investigate the effect of Euphorbia humifusa effective fraction (EHEF) on the CYP51 enzyme activity, the lanosterol content and the MEP, SUB gene expression of Trichophyton rubrum. Trichophyton rubrum was treated by EHEF for 7 days at 26 degrees C. The activity of CYP51 enzyme of Trichophyton rubrum in the cell membrane was determined by using ELISA kit, and the lanosterol content was investigated by using high performance liquid chromatography (HPLC), and the MEP, SUB gene expression of Trichophyton rubrum was detected with the reverse transcription polymerase chain reaction (RT-PCR) method. Results showed that EHEF can decrease the membrane CYP51 enzyme activity, and it also can accumulate the fungal lanosterol in a dose-dependent manner, and it also can decrease the gene expression of MEP and SUB. The antifungal mechanism of EHEF may be related to the inhibition on CYP51 enzyme activity, and to the effects on fungal cell membrane ergosterol biosynthesis. It may also play an antifungal effect by inhibiting the MEP, SUB gene expression of fungal proteases.

Objective:To evaluate the rehabilitation efficacy of early mobilization based on collaboration care model for patients with laparoscopic colorectal surgery.Methods:Cluster sampling method was used in the department to recruit colorectal cancer patients with laparoscopic surgery. The control group (49 cases) received routine perioperative care and exercise, and the intervention group (47 cases) received the coordinated early mobilization combined with routine perioperative care and exercise, from January to March 2019. Primary outcome were health status and the proportion of patients returning to preoperative functional walking capacity (6-min walk test) at 4 weeks after surgery. The in-hospital mobilization (time out-of-bed), time to achieve discharge criteria, time to recover gastrointestinal function and complication rate were explored.Results:In intervention group,89.4%(42/47) of patients achieved mobilization target on 4 days after surgery compared with 42.6%(20/47) on the day of surgery. Time out of bed were greater in the intervention group compared with the control group, and there were differences between the two groups( Z values were -8.437--7.381, P<0.01). Time to recover gastrointestinal function and the recovery of energy on 3 days after surgery were (58.74±17.41) h, (59.02±9.46) points in the observation group, and (71.82±21.53) h, (62.61±7.68) points in the control group, and there were significant differences between the two groups ( t values were -3.263, -2.046, P<0.05). But other outcome measures were not different between the two groups ( P>0.05). Conclusions:For colorectal laparoscopic surgery patients, the coordinated early mobilization improved the adherence to ambulation, in-hospital mobilization, time to recover gastrointestinal function and recovery of energy to promote rehabilitation.

Objective:To explore the related factors of postoperative adjuvant therapy for cervical cancer stagedⅠB1-ⅡA2 [according to 2018 International Federation of Gynecology and Obstetrics (FIGO) staging standard], and to establish a nomogram model to predict the risk of postoperative adjuvant therapy for locally advanced cervical cancer.Methods:A total of 714 patients with cervical squamous cell cancer staged FIGO ⅠB1-ⅡA2 treated by surgery in Anhui Provincial Hospital were selected as the research objects from January 2009 to December 2019, and their clinicopathological data were analyzed. Multiple logistic regression analysis was used to determine the influencing factors, and a nomogram model was established to predict the risk of postoperative adjuvant treatment of cervical cancer. The predictive performance of the model was evaluated with the consistency index (C-index), and the compliance of the model was evaluated with the calibration curve.Results:Univariate analysis suggested that postoperative adjuvant therapy for cervical cancer was associated with gravidity ( χ2=11.506, P=0.001), underlying disease (hypertension or diabetes) ( χ2=7.668, P=0.006), squamous cell cancer antigen (SCC-AG) level ( χ2=19.392, P<0.001), imaging risk factors ( χ2=16.392, P<0.001), FIGO stage ( χ2=25.686, P<0.001), tumor size ( χ2=9.392, P=0.025) and surgical path ( χ2=16.590, P<0.001). Multivariate logistic regression analysis suggested that the number of pregnancy >2 times ( OR=1.951, 95% CI: 1.355-2.808, P<0.001), SCC-Ag ≥1.5 μg/L ( OR=2.021, 95% CI: 1.444-2.829, P<0.001), FIGO stage ⅠB3-ⅡA2 [ⅠB3 ( OR=1.933, 95% CI: 1.139-3.282, P=0.015); ⅡA1 ( OR=2.723, 95% CI: 1.556-4.765, P<0.001); ⅡA2 ( OR=3.159, 95% CI: 1.502-6.646, P=0.002)], with underlying disease (hypertension or diabetes) ( OR=1.867, 95% CI: 1.051-3.318, P=0.033), imaging risk factors ( OR=1.997, 95% CI: 1.127-3.537, P=0.018), without neoadjuvant therapy [preoperative neoadjuvant therapy for 1 cycle ( OR=0.402, 95% CI: 0.207-0.783, P=0.007)] and laparoscopic surgery ( OR=2.177, 95% CI: 1.524-3.112, P<0.001) were independent influencing factors for postoperative adjuvant treatment of cervical cancer. Based on the screened variables, the nomogram model to predict the risk of postoperative adjuvant treatment for cervical cancer has good predictive performance (C-index was 0.702) and compliance. Conclusion:The number of pregnancy >2 times, SCC-Ag ≥1.5 μg/L, FIGO stage ⅠB3-ⅡA2, with underlying disease (hypertension or diabetes), imaging risk factors, without neoadjuvant therapy, and laparoscopic surgery are independent influencing factors for postoperative adjuvant treatment of cervical cancer. A nomogram model has been constructed to predict the risk of postoperative adjuvant therapy for locally advanced cerrical cancer, and it can provide evidence for clinical treatment selection.

The aim of this study was to observe whether necroptosis is involved in the process of cardiac hypertrophy induced by pressure overload. SD rats underwent transverse abdominal aortic constriction (TAC) operation for establishing cardiac hypertrophy model. The structure and function of the left ventricle of rats were evaluated via echocardiography, left ventricular mass index, the expression of markers of cardiac hypertrophy and histological detection. Real-time PCR and Western blot were used to measure the gene and protein expression of receptor interacting protein kinase 1 and 3 (RIPK1 and RIPK3, the necroptosis markers) respectively. Four weeks after TAC operation, rat model for cardiac hypertrophy was established. The experimental data showed that the gene and protein expressions of RIPK1 and RIPK3 in the rat heart hypertrophic tissues after TAC for 4 weeks were increased significantly compared with those in the sham group. HE staining showed cardiomyocytes injury and hypertrophy in the hearts of TAC rat models. By transmission electron microscope, we observed that mitochondria of cardiomyocytes were damaged seriously in the TAC models. Treatment with losartan used, the selective antagonist of angiotensin II type I receptor could improve the cardiac function of TAC rats. Moreover, losartan treatment decreased the expression of RIPK1 and RIPK3 in heart tissues of TAC rats. The results suggest that necroptosis occurrs in the process of cardiac hypertrophy with pressure overload, and losartan could alleviate the cardiac hypertrophy and inhibit necroptosis.

The aim of this study is to construct specific shRNA expressing plasmids, and to observe their effects on H9c2 cardiomyocytes injury induced by hypoxia/reoxygenation (H/R). RIPK1 and RIPK3 are the key kinases mediating the process of necroptosis. Using recombinant DNA technology, we inserted the synthetic shRNA into pSUPER vector to construct RIPK1-shRNA or RIPK3-shRNA plasmid respectively. We transfected H9c2 cardiomyocytes with the two shRNA plasmids respectively, before we treated them with H/R stimulation. Then, we measured the relevant genes and proteins by real-time PCR and Western blot. Meanwhile,we detected the markers of necroptosis and cardiomyocytes injury. The results showed that inhibition of ripk1 or ripk3 gene expression by its specific shRNA might protect the cardiomyocytes injury induced by H/R stimulation.
