Objective To investigate the effect of telephone call follow-up on compliance with opening-mouth exercises among nasopharyngeal carcinoma(NPC)patients with radiotherapy-induced difficulty in opening mouth.Methods Sixty four nasopharyngeal carcinoma patients undergoing radiotherapy were randomized into control group(n=31)and observation group(n=31).The former group was given health education and instructions for functional exercises of opening mouth at discharge and regular return visits after discharge,and the observation group received regular telephone call follow-ups by an appointed nurse besides the same treatment as in the control group.The two groups were compared in regard to the compliance with the exercises of opening mouth and the incidences of difficulties in opening mouth at the first and second years after discharge. Results The compliance of the observation group was significantly higher that in the control group(P<0.01).The incidences of difficulties in opening mouth in the observation group were significantly smaller than that in those of the control at the first and second years after discharge(P<0.01). Conclusion Telephone call follow-ups are effective in the improvement of compliance of functional exercises in NPC patients with radiotherapy-induced difficulty in opening mouth,the reduction of the incidence of mouth-opening problems and the improvement of their quality of life.

Objective To compare the efficacies between interventional embolization and surgical clipping in treatment of ruptured intracranial aneurysms to provide an evidence‐based basis for selecting the clinical treatment scheme .Methods The related randomized controlled trail(RCT) literatures on the effects of interventional embolization and surgical clipping were retrieved from the databases of Pubmed ,Cochrane ,Medline and Embase .The screening was independently performed by two researchers according to the including and excluding criterion .The occurrence rate of adverse reactions ,postoperative 1‐year mortality rate ,re‐bleeding rate ,occurrence rate of vasospasm and ischemic cerebral infarction served as the measurement indicators .The data were extracted and performed the meta analysis by the RevMan5 .3 software .Results Sixteen RCT literatures were included for conducting analy‐sis ,involving 7 373 patients ,in which 3 092 cases adopted interventional embolization and 4 281 cases adopted surgical clipping .The occurrence rate of adverse events(OR=1 .25 ,95% CI ,1 .12-1 .40 ;P<0 .000 1) and re‐bleeding rate(OR=0 .43 ,95% CI ,0 .28 -0 .66 ;P=0 .000 1) in the interventional embolization group were lower than those in the surgical clipping group ;however ,there were no statistical differences between the interventional embolization group and surgical clipping group in the postoperative 1‐year mortality rate(OR=1 .13 ,95% CI ,0 .92-1 .39 ;P=0 .23) ,incidence rate of vasospasm (OR=1 .41 ,95% CI ,0 .99-2 .02 ;P=0 .06) and incidence rate of ischemic cerebral infarction(OR=0 .66 ,95% CI ,0 .42 -1 .05 ;P=0 .08) .Conclusion The current clinical re‐search evidences indicate that using the interventional embolization in treating ruptured intracranial aneurysms can obviously reduce the occurrence rate of adverse events than the surgical clipping ,but increases the re‐bleeding rate .The postoperative 1‐year mortali‐ty rate ,incidence rate of vasospasm and incidence rate of ischemic cerebral infarction have no obvious difference between these two kinds of operation .

OBJECTIVETo investigate the dynamic changes of type I collagen, and the activity of metalloproteinases-1 (MMP-1) and tissue inhibitor of metalloproteinases-1 (TIMP-1) after angioplasty.

METHODSThe restenotic model of iliac arteries of domestic microswine was established with hypercholesterol feed plus two angioplasties. Angioplastied vessels were harvested at the end of 1, 2, 3 and 6 months after the second angioplasty. Immunohistochemistry, transmission electronic microscopy and image quantitative analysis techniques were employed to study neointimal proliferation, the phenotype of vascular smooth muscle cells (VSMC) and the expression of type I collagen, MMP-1 and TIMP-1.

RESULTSThe peak of vascular neointimal proliferation was at 3 months after angioplasty. The expression of type I collagen gradually increased from 1 to 6 months after angioplasty. For MMP-1, expression was lower in the early stage after angioplasty but increase to normal levels of control vessels at 6 months after angioplasty. Expression of TIMP-1 rapidly increased in the early phase after angioplasty, reached peak at 3 months and maintained the high level till 6 months after angioplasty. Meanwhile, the VSMC was predominantly the synthetic phenotype at the early stage and was transformed to the contractive phenotype at the late stage after angioplasty. The ratio of TIMP-1 and MMP-1 was positively related to the area of the neointima and the expression of type I collagen respectively (P < 0.01).

CONCLUSIONType I collagen increased gradually after angioplasty, which might be determined by the ratio of TIMP-1/MMP-1 and also related to the phenotype of VSMC.

Background/Aims: The incidence and prevalence of inflammatory bowel disease (IBD) is rising in Asia recently. The study aimed to obtain a comprehensive understanding of the current status of drug therapy and monitoring for IBD in Asia. Methods: A questionnaire investigation on drug therapy and monitoring for IBD was conducted right before the 6th Annual Meeting of Asian Organization for Crohn’s & Colitis. Questionnaires were provided to Asian physicians to fill out via emails between March and May 2018. Results: In total, responses of 166 physicians from 129 medical centers were included for analysis. Among the surveyed regions, the most average number of IBD specialist gastroenterologists and nurses was 4.8 per center in Taiwan and 2.5 per center in Mainland China, respectively. 5-Aminosalicylic acid/sulfasalazine (99.4%) was the most preferred first-line choice for mild-moderate ulcerative colitis (UC), meanwhile corticosteroid (83.7%) was widely applied for severe UC. The first-line medication for Crohn’s disease (CD) markedly varied as corticosteroid (68.1%) was the most favored in Mainland China, Japan, and South Korea, followed by infliximab (52.4%) and azathioprine (47.0%). Step-up strategy was preferred in mild-moderate UC (96.4%), while 51.8% of the physicians selected top-down treatment for CD. Only 25.9% and 17.5% of the physicians could test blood concentration of infliximab and antibody to infliximab in their hospitals, respectively. Conclusions The current status of drug therapy and monitoring for IBD in Asia possesses commonalities as well as differences. Asian recommendations, IBD specialist teams and practice of therapeutic drug monitoring are required to improve IBD management in Asia.

Objective To establish and evaluate a talent training system for hospital information pharmacists based on a competency model,thereby enhancing refined management of pharmaceutical affairs in hospitals and promoting high-quality development of pharmacy services.Methods The current development status of hospital information pharmacists at home and abroad was examined.A competency model for hospital information pharmacist positions was established using methods such as behavioral event interviews.In conjunction with this model,training course outlines addressing knowledge and capability requirements were developed.National skill training classes for hospital information pharmacists were conducted using innovative teaching methods like scenario simulation and case discussion.Training effectiveness was evaluated by tracking participants'work performance and scientific research achievements in the field of pharmaceutical information through questionnaire surveys before and after the training.Results The hospital information pharmacist positions competency model was constructed in four parts:knowledge,experience,skills,and personal traits.Based on this model,a training system for hospital information pharmacists was established,which included setting job responsibilities and performance indicators,establishing a pharmacy information department system,designing a series of training courses and publishing textbooks,founding national training classes,creating a specialized question bank,and developing a digital pharmacy network platform.The project team tracked the work performance and scientific research achievements of participants before and after training,using the national hospital information pharmacist training class hosted by the Guangdong Pharmaceutical Association as an example.From 2018 to 2024,a total of 465 information pharmacists from 298 hospitals across 28 provinces and cities were trained over seven sessions.Questionnaires were sent to participants who had completed at least one year since graduation,and 236 valid responses were received.Of these,169(71.6% )participants reported playing a major role in pharmacy informatization projects after the training,and 65(27.5% )participants published papers,applied for projects,or filed for patents after the training,with the majority related to pharmacy automation and informatization.Conclusion A competency model for hospital information pharmacist positions was constructed and applied nationwide,achieving favorable results.

To investigate the bioelectrochemical enhanced anaerobic ammonia oxidation (anammox) nitrogen removal process, a bioelectrochemical system with coupled anammox cathode was constructed using a dual-chamber microbial electrolysis cell (MEC). Specifically, a dark incubation batch experiment was conducted at 30 ℃ with different influent total nitrogen concentrations under an applied voltage of 0.2 V, and the enhanced denitrification mechanism was investigated by combining various characterization methods such as cyclic voltammetry, electrochemical impedance spectroscopy and high-throughput sequencing methods. The results showed that the total nitrogen removal rates of 96.9%±0.3%, 97.3%±0.4% and 99.0%±0.3% were obtained when the initial total nitrogen concentration was 200, 300 and 400 mg/L, respectively. In addition, the cathode electrode biofilm showed good electrochemical activity. High-throughput sequencing results showed that the applied voltage enriched other denitrifying functional groups, including Denitratisoma, Limnobacter, and ammonia oxidizing bacteria SM1A02 and Anaerolineaceae, Nitrosomonas europaea and Nitrospira, besides the anammox bacteria. These electrochemically active microorganisms comprised of ammonium oxidizing exoelectrogens (AOE) and denitrifying electrotrophs (DNE). Together with anammox bacteria Candidatus Brocadia, they constituted the microbial community structure of denitrification system. Enhanced direct interspecies electron transfer between AOE and DNE was the fundamental reason for the further improvement of the total nitrogen removal rate of the system.

The lack of clear definition and classification for “moderate ulcerative colitis (UC)” creates ambiguity regarding the suitability of step-up versus top-down treatment approaches. In this paper, experts address crucial gaps in assessing and managing moderate UC. The Asia-Pacific, Middle East, and Africa Inflammatory Bowel Disease Coalition comprised 24 experts who convened to share, discuss and vote electronically on management recommendations for moderate UC. Experts emphasized that the goal of treating UC is to attain clinical, biomarker, and endoscopic remission using cost-effective strategies such as 5-aminosalicylates (5-ASAs), well-tolerated therapy that can be optimized to improve outcomes. Experts agreed that 5-ASA therapy could be optimized by maximizing dosage (4 g/day for induction of remission), combining oral and topical administration, extending treatment duration beyond 8 weeks, and enhancing patient adherence through personalized counselling and reduced pill burden. Treatment escalation should ideally be reserved for patients with predictors of aggressive disease or those who do not respond to 5-ASA optimization. Premature treatment escalation to advanced therapies (including biologics and oral small molecules) may have long-term health and financial consequences. This paper provides consensus-based expert recommendations and a treatment algorithm, based on current evidence and practices, to assist decision-making in real-world settings.
