Objective:To evaluate the reporting quality of clinical guidelines on skin diseases published in journals in China.Methods:The CNKI, VIP, Wanfang and SinoMed databases were searched from January 2009 to October 2019 for clinical guidelines on skin diseases published in journals in China. Two reviewers independently screened the literature, and extracted and cross-checked data. The reporting quality of these clinical guidelines was evaluated by using the Reporting Items for Practice Guidelines in Healthcare (RIGHT) , and statistical analysis was carried out with Excel 2017 software.Results:A total of 17 clinical guidelines on skin diseases were included, including 13 Western medicine guidelines and 4 Chinese medicine guidelines. Among the 13 Western medicine guidelines, the number of guidelines reporting the following areas in the RIGHT statement, namely basic information, background, evidence, recommendations, review and quality assurance, funding and declaration and management of interests, and other information, was 9, 6, 0, 4, 0, 1 and 1 respectively; among the 4 Chinese medicine guidelines, the number of guidelines reporting the above 7 areas in the RIGHT statement was 4, 3, 3, 3, 3, 2 and 2 respectively.Conclusion:There is still considerable room for improvement in the overall reporting quality of clinical guidelines on skin diseases published in journals in China during the past 10 years, and the RIGHT statement is recommended for improving the reporting quality in guideline development.

ObjectiveTo explore the release of exogenous growth factors from small intestinal submucosa (SIS) in bladder regeneration. MethodsThe release of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) from SIS in vitro were evaluated by ELISA and MTT method. The defected bladder walls of rats in experimental group were repaired with porcine small intestinal submuscosa. Partial bladder mucosa and smooth muscle of the rats in control groups were destroyed. At regular intervals, the VEGF and bFGF expression were observed by histological and immunohistochemical methods. ResultsThe concentration of bFGF and VEGF released in vitro from SIS in PBS solution were (121.8±2.683) ng/L and (93.8±3.033) ng/L respectively, and showed proliferation of vascular endothelial cell. In the SIS framework, the capillary and smooth muscle were observed followed histological evaluation. The weak expression of VEGF and bFGF in both experimental and control groups were found in the first week. Since the second week the VEGF and bFGF expression in experimental group began to increase with a peak in the 6th week, and began to decrease after 8 weeks. In the control group, the weak VEGF and bFGF expression were shown during the observation. ConclusionSIS functions as a carrier for exogenous growth factors release in rat bladder regeneration.

BACKGROUNDPrevious researches about necrotic pancreatic tissue infections are numerous, but the study on systemic infection related to the severe acute pancreatitis (SAP) treatment period is limited. This study aimed to investigate the distribution and drug resistance of pathogenic bacteria in patients who had hepatobiliary surgery for SAP during the past three years.

METHODSA retrospective study was conducted on the distribution, category and drug resistance of pathogenic bacteria in patients who had hepatobiliary surgery for SAP from 2008 to 2011.

RESULTSA total of 594 pathogenic bacteria samples were isolated. Among them 418 isolates (70.4%) were Gram bacteria negative, 142 isolates (23.9%) were Gram bacteria positive, and 34 isolates (5.7%) were found fungi. The most common Gram negative bacteria were Escherichia coli (19.8%), and the dominant Gram positive pathogenic bacteria were Enterococcus faecium. The distribution of SAP-related infectious pathogens was mainly in peritoneal drainage fluid, sputum, bile, and wound secretions. Almost all the Gram negative pathogenic bacteria were sensitive to carbapenum. Extended-spectrum β-lactamases (ESBLs) producing strains were more resistant to penicillins and cephalosprins than the ESBLs non-producing strains. Staphylococcus was sensitive to vancomycin and linezolid. The drug resistance of meticillin-resistant staphylococcus (MRS) to commonly used antibiotics was higher than meticillin-sensitive streptococcus (MSS). Enterococcus sp. exhibited lower drug-resistance rates to vancomycin and linezolid.

CONCLUSIONSGram negative bacteria were the dominant SAP-related infection after hepatobiliary surgery. A high number of fungal infections were reported. Drug resistant rates were high. Rational use of antibiotics according to the site of infection, bacterial species and drug sensitivity, correctly executing the course of treatment and enhancing hand washing will contribute to therapy and prevention of SAP-related infection and decrease its mortality.

METHODSTotally 40 SD rats were randomly divided into the normal control group (Control), the propylthiouracil (PTU) group, the adriamycin (ADR), and the ADR + PTU group. Normal saline was used as equivalent solvent of each group. Rats in the Control group were intragastrically and intraperitoneally injected with normal saline. Rats in the PTU group were intragastrically injected with PTU suspension and intraperitoneally injected with normal saline. Rats in the ADR group were intragastrically injected with ADR solution and intraperitoneally injected with normal saline. And rats in the ADR + PTU group were intragastrically injected with PTU suspension and intraperitoneally injected with ADR solution. The dose of PTU was 0.2% of daily forage weight, once daily. The dose of ADR was 3.5 mg/kg, once per week. The modeling lasted for 6 weeks. Left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), brain natriuretic peptide (BNP), heart rate (HR), respiratory rate (RR), urine output, ear temperature, exhaustive swimming test (EST), Tri-iodothyronine (T3), tetra-iodothyronine(T4), thyroid stimulating hormone (TSH) as well as heart, lung, liver weight indices and their pathological sections were integrated and compared.

RESULTSCompared with the Control group, LVEF, LVFS, BNP, HR, RR, heart, lung, liver weight indices, urine output, ear temperature, EST, and T3, T4, and TSH changed significantly in the ADR group, the PTU group, and the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure occurred in pathological sections of heart, lung, and liver. Compared with the ADR group, LVEF, LVFS, BNP, and lung, liver weight indices, urine output, ear temperature, T3, T4, and TSH changed significantly in the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure were more serious in pathological sections of heart, lung, and liver. Compared with the PTU group, LVEF, LVFS, BNP, HR, RR, urine output, EST, T4, heart and lung weight indices changed significantly in the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure were quite serious in pathological sections of heart, lung, and liver.

CONCLUSIONADR + PTU was an appropriate method to establish CHF rat model of XQD-BSES.

OBJECTIVETo study and evaluate the curative effect and mechanism of Qiangxin Granule (QXG) in intervening chronic heart failure (CHF) rats with Xin-qi deficiency complicated blood stasis and edema syndrome (XQD-BS-ES).

METHODSTotally 72 SD rats of clean grade were randomly divided to the normal control group (n =10) and the model group (n = 62). The XQD-BS-ES rat model was established by adriamycin plus propylthiouracil method. Survived modeled rats were then randomly divided to 5 groups i.e., the model group (n = 11, administered with normal saline by gastrogavage), the Western medicine (WM) group (n =11 , administered with perindopril and hydrochlorothiazide by gastrogavage), the low dose QXG (QXG(L)) group (n = 11, administered with 9.26 g/kg QXG by gastrogavage), the middle dose QXG (QXG(M)) group (n = 11, administered with 18.52 g/kg QXG by gastrogavage), the high dose QXG (QXG(H)) group (n = 11, administered with 37.04 g/kg QXG by gastrogavage). After 4 weeks of treatment, left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), brain natriuretic peptide (BNP), heart rate (HR), respiratory rate (RR), urine output, ear temperature, exhaustive swimming test (EST), tri-iodothyronine (T3), tetra-iodothyronine (T4), thyroid stimulating hormone (TSH), as well as heart, lung, liver weight index and their pathological sections, and high sensitivity C-reactive protein (HS-CRP), angiotensin II (Ang II), carbohydrate antigen 125 (CA125) were detected and compared.

RESULTSCompared with the normal control group, LVEF, LVFS, BNP, HR, RR, urine output, ear temperature, EST, T3, T4, TSH, HS-CRP, Ang II, and CA125 changed significantly in the model group (P < 0.01). Compared with the model group after treatment, LVEF, LVFS, BNP, urine output, EST, T4, heart and liver weight index, HS-CRP, Ang II, CA125 were significantly improved in each QXG group (P < 0.05, P < 0.01). Moreover, TSH was improved in the QXGL and QXG(M) groups (P < 0.05); ear temperature and T3 in the QXG(M) were also improved (P < 0.05); the lung weight index decreased in the QXG(M) and QXG(H) groups (P < 0.01). Compared with the WM group, T4 and CA125 were obviously improved in all QXG groups (P < 0.01); BNP and ear temperature were obviously improved in QXG(L) and QXG(M) groups (P < 0.05, P < 0.01); LVEF, LVFS and TSH were obviously improved in the QXG(M) group (P < 0.05, P < 0.01). And as far as each treatment group, LVEF, LVFS, urine output increased significantly after treatment (P < 0.01); EST obviously increased in QXG(M) and QXG(H) groups (P < 0.01); ear temperature increased in all QXG groups (P < 0.05, P < 0.01). Moreover, compared with the model group, pathological changes of heart, lung, and liver were improved to some degree in each treatment group, especially in the QXG(M) group.

CONCLUSIONSGood curative effect was shown in each QXG group. QXG could improve LVEF, LVFS and BNP of CHF rats of XQD-BS-ES, as well as T3, T4, TSH, EST, urine output, and ear temperature. Moreover, QXG showed superiority than WM group in this respect.

Single-docking robot-assisted laparoscopic radical nephroureterectomy is difficult to deal with the distal ureter and bladder. Thirty-two patients with ureter carcinoma underwent single-docking robot-assisted nephroureterectomy in rectus rectilinear cannula placement in our hospital. The advantages include lower surgical difficulty, shorter operation time, less surgical bleeding and damage. This surgical method is a safe and effective minimally invasive treatment for ureter carcinoma.

Aim To investigate the protective role of salvianolic acid B ( Sal B ) on cardiac hypertrophy in type 2 diabetes mice , and to explore its influence on peroxisome proliferator activated receptors-α( PPARα) .Methods The type 2 diabetes melitus ( T2DM) mouse model was established by 4 weeks ' high fat diets feeding and one time STZ intraperitoneal injection .The animals were randomly divided into:control, T2DM, T2DM+SalB(100 mg· kg -1 · d-1 ) and Sal B(100 mg· kg -1 · d-1 ) groups.Eight weeks later, heart weight, tibial length, cross section area of cardiomyocytes , protein expression of PPARαin heart tissue were recorded .In vitro, high glucose and high insulin ( HGI ) were used to induce hypertrophic growth in cultured neonatal rat cardiomyocytes ( NRC-Ms) .And cell surface area , 3 H-leucine incorporation , 3 H-D-glucose uptake and PPARαprotein level were measured to observe the effect of Sal B and MK 886, a PPARαinhibitor.Results In T2DM model mice, Sal B could lower heart weight/tibial length and cross sec-tion area of cardiomyocytes , while PPARαprotein level in hearts were improved .In cultured cardiomyocytes , Sal B ( 10 ～100 μmol · L-1 ) ameliorated the in-creased levels of cell surface area ,3 H-leucine incorpo-ration and improved the decreased 3 H-D-glucose up-take and PPARαexpression induced by HGI . But those function could be abolished by MK 886.Conclu-sion Sal B ameliorates cardiac hypertrophy in T 2DM mice, which may be related to its function on PPARαactivation .

OBJECTIVETo observe the metabolin difference between hypertension patients of Gan-yang hyperactivity syndrome (GYHS) and those of yin-yang deficiency syndrome (YYDS).

METHODSTotally 26 hypertension patients at the Base for Chinese Medicine Clinical Research of Hypertension from June 2009 to May 2010 were assigned to two groups, the GYHS group (12 cases) and the YYDS group (14 cases). Besides, 14 healthy volunteers from the affiliated community were recruited as the control group. Their blood plasmas and principle component analysis (PCA) were analyzed by high performance liquid chromatography-time of flight mass spectrometry (HPLC-TOFMS) technology. The correlated metabolin and their metabolic pathways were identified using Metlin Database.

RESULTSThe PCA chart showed that the dispersion was larger in the control group than in the other two groups. The data of the GYHS group and the YYDS group showed gathering tendency. Further PCA results showed good spatial separation between the two groups, with significant difference between them. Totally 6 metabolins were detected. Of them, estrodiol, leucotriene, ceramide, and glucose-ceramide increased more in the GYHS group, while triglyceride and diacylglycerol increased more significantly in the YYDS group.

CONCLUSIONSHPLC-TOFMS is capable of primarily identifying and clarifying different metabolic modes of the GYHS and the YYDS. Different contents of estrodiol, leucotriene, ceramide, glucose-ceramide, triglyceride, and diacylglycerol might probably become the differential points for identifying the two syndrome types.
