Supplementary concept records ( SCB ) can effectively supplement and expand MeSH by forming the mapping between SCB and MeSH. Chinese herbal medicine terms indentified by MeSH Browser in SCB were analyzed in aspects of their distribution,single medicine,abstracted compositions,compound prescription,classical prescription, slef-made prescription, and use frequency,which showed the supplementary concepts in relation with Chinese herbal medicine and the existed problems. Suggestions were put forward for the use of Chinese herbal medicine terms in MeSH SCB, such as promoting their standardization, and use of standard terms when scientists publish their papers and retrieve papers from databases.

Objective To investigate the expression of peroxisome proliferator-activated receptor-γ(PPAR-γ) and angiotensin receptor (AT2R) in chronic pancreatitis tissue. Methods Between April 2006 and February 2009, 24 patients were pathologically diagnosed as chronic pancreatitis were enrolled and 12 samples of normal pancreatic tissues were treated as controls. Immunohistochemical staining was used to detect PPAR-γ and AT1R, AT2R expression in pancreatic tissues. Results PPAR-γ and AT1R were mostly negatively expressed in normal pancreatic tissues, the positive scores were 0.33±0.49 and 0.42 ± 0. 51, respectively, while AT2R were weakly positively or negatively expressed in acinus and islet cell, and it was weakly positively expressed in ductal epithelial cells, the positive score was 2. 33 ± 1. 37. In chronic pancreatitis tissue, PPAR-γ, AT1R and AT2R were positively expressed in acinus, ductal epithelial cells, and islet cell, the positive scores were 3.28 ± 2.46, 4.36 ± 2.80 and 4.61 ± 2.89, which were significantly higher than those in the normal group (P<0.01, P <0.01, P<0.05). Conclusions PPAR-γ, AT1R and AT2R were positively expressed in chronic pancreatitis tissue, and they may be the treatment target of chronic pancreatitis.

Objective To investigate the impact of pelvic muscle training (PFMT) on the quality of life (QOL) and incidence of postoperative complications in stress urinary incontinence (SUI) patients after tension-free vaginal tape surgery (TVT). In order to provide evidence for clinical nurses taking measures to promote rehabilitation of postoperative patients. Methods A total of 101 female SUI patients who underwent TVT surgery were included in this study. 50 patients in the trial group received pelvic muscle training guidance by one-to-one for 3months while 51 patients in the control group were instructed to the routine discharge guidance. All patients were asked to finish the Incontinence-specific Quality of Life questionnaire (I-QOL) at the day before surgery and 3 months after the surgery, respectively. And incidence of postoperative complications were evaluated at 3 months after the surgery. Results A total of 94 participants completed all questionnaires, including 48 patients of the trial group and 46 patients of the control group. The postoperative score of I-QOL in the trial group were higher than that of control group (94.32 vs. 90.34, Z=3.863, P<0.01). Further analysis found that avoidance and limiting behaviors domain score (90.63 vs.87.50, Z=3.227, P<0.01) and psychosocial impacts domain score (97.22 vs. 90.28, Z=4.186, P<0.01) in the trial group were higher than that of control group. The incidence of postoperative urgency urinary incontinence was significantly difference between the two groups (χ2=4.953,P=0.026), the proportion were 16.67% (8/48) in the trial group and 36.96% (17/46) in the control group, respectively. According to the results, the patients′overall quality of life of the trial group was better than that of control group after surgery. Conclusions Postoperative SUI patients′implementation of pelvic muscle training can significantly increase their quality of life and can decrease the incidence of urgency urinary incontinence.

Herpesviruses is one of the most common human infectious diseases, which can be divided into different types based on clinical infection degree.Herpes simplex virus usually results in buccal and genital mucocutaneous infections, while cytomegalovirus is the most common opportunistic pathogen associated with significant morbidity and mortality in immunocompromised hosts, especially in transplant and cancer patients.Although nucleoside analogues are effective antiviral drugs, the emergence of drug-resistant viruses has created a barrier for the treatment of herpesviruses infections, especially in immunocompromised patients.Therefore, novel therapeutic agents are needed to avoid the limitations of drug resistance.In this article, research progress in the therapeutic agents for drug-resistant herpesviruses was reviewed from the aspects of non-nucleoside analogues, novel antiviral targets and newly antiviral mechanisms.

Objective To investigate the impact of paced QRS duration (pQRSd) on heart function in patients with right ventricular apical pacing. Methods Seventy-six patients with Ⅲ° atrioventricular block received pacemaker treatment were enrolled and randomized into group A (pQRSd < 190 ms, n = 52) and group B(pQRSd≥ 190 ms, n = 24). The concentration of brain natriuretic peptide (BNP),parameters of left atrial diameter (LAD), left ventricular ejection fracetion (LVEF), left ventricular end diastolic diameter (LVEDD), left ventricular end systolic dimension (LVEDD) were measured before operation, at 12 months and 24 months after implanting, respectively. The parameters of echocardiography assay, the concentration of BNP and the incidence of heart failure event after implantation were compared between two groups. Results At 12 months after implanting, LVEF of the patients in the group B decreased significantly compared with that of group A (P < 0.05). However, the echocardiography paramenters and the concentration of BNP were not significantly different between the two groups (P > 0.05). At 24 months after implanting, LAD、LVEDD、LVESD of group B increased significantly compared with those of group A [LAD,( 44.5 ± 6.2) mm vs (41.6 ± 5.1) mm, LVEDD, (52.7 ± 9.3) mm vs (48.2 ± 7.5) mm, LVESD, (37.5 ± 5.6) mm vs (33.8 ± 4.9)mm, each P < 0.05, respectively]. The concentration of BNP of group B increased significantly [(408.2 ± 102.1)ng / L vs (243.7 ± 92.8)ng / L, P < 0.001], and LVEF of the patients in group B decreased significantly compared with those of group A [(46.3 ± 6.8)% vs (51.6 ± 5.2)%, P < 0.001], respectively. No significant difference in the incidence of heart failure event (41.7% vs 26.9%, P > 0.05)between two groups during 24-month follow-up. Conclusion The prolonged paced QRS duration has a detrimental effect on long-term cardiac function during RVA pacing in patients with Ⅲ°atrioventricular block.
