ABSTRACT
Background: No effective medication is available for symptomatic bradyarrhythmia, particularly in low socioeconomic status (SES) population. Objective: To explore the safety and efficacy of Yuanjiang decoction, a traditional Chinese medicinal prescription, for symptomatic bradyarrhythmia on a compassionate-use basis. Methods: This compassionate-use study was conducted in Beijing, China between January 2019 and January 2020. Eligible participants were recruited and treated with Yuanjiang decoction (composed of 6 Chinese herbal medicines), 200 ml twice daily for 16 weeks. Analyses were done with the intention-to-treat (ITT) approach. The primary outcome measure was the proportion of participants who achieved a favorable treatment outcome at 16 weeks. Results: As of January 2020, 184 patients were included. After 16-weeks treatment, 12 participants were lost to contact while 21 participants were terminated from this study, with a drop-out rate of 17.93%. The most common treatment-related adverse events were xerostomia (6.52%), constipation (6.45%) and sleepiness (3.26%). The proportion of participants with favorable treatment outcome was 65.22% at 4 weeks, 59.78% at 8 weeks (OR: 1.11, 95% CI: 0.71-1.73), 61.41% at 12 weeks (OR: 1.16, 95% CI: 0.92-1.45) and 60.87% at 16 weeks (OR: 1.15, 95% CI: 0.98-1.35). In the multifactor regression analysis, the favorable treatment outcome at 16 weeks was significantly associated with completing at least 8 weeks treatment (OR: 2.053, 95% CI: 1.064-3.560), while unfavorable treatment outcome was significantly associated with an atrioventricular block (OR: 0.255, 95% CI: 0.083-0.784), current smoking (OR: 0.343, 95% CI: 0.027-0.487), and syncope in the month before treatment (OR: 0.321, 95%CI: 0.114-0.904). Conclusion: This compassionate-use study showed encouraging outcomes of treatment with Yuanjiang decoction, without serious adverse events. This study identified several key factors that may affect outcomes. These findings helped inform the design and assess the feasibility of a large-scale randomized clinical trial.
ABSTRACT
This study examined the prevalence of primary open-angle glaucoma (POAG) among residents aged ≥50 years living in Yongchuan district of Chongqing. Stratified cluster sampling was employed in random selection to estimate the prevalence of glaucoma from April to June, 2005. Twenty-nine villages or neighborhood communities were randomly selected in urban area (Zhongshan Road), suburban area (Shanjiao Town) and exurban area (Zhutuo Town) of this district. All the respondents underwent detailed ophthalmic examinations. The examinations included questionnaire investigation, visual acuity test, naked-eye examination, measurement of peripheral anterior chamber depth (Van Herrick's technique), detection of intraocluar pressure (IOP) with a Perkins hand-held applanation tonometer (HA-2) and examination of the optic disc by using a 78 diopters (D) lens (including the cup-disc ratio, cup/disc ratio asymmetries, horizontal and vertical diameter, notching and optic disc hemorrhages). A total of 5938 residents were actually examined, and the response rate was 85.19%. The crude prevalence of POAG was 0.86% (n=51/5938, 95% CI 0.64%-1.11%). There were 24 males and 27 females in the glaucoma group. The glaucoma prevalence was not significant different in case number between the male and female subjects (P=0.4900). Furthermore, no association between age or schooling and POAG was noted (P=0.8030, 0.0734). Out of 51 subjects with POAG, unilateral glaucoma-related blindness occurred in 38 subjects (74.5%) and bilateral glaucoma-related blindness was found in 7 subjects (13.7%). This study exhibited that the prevalence of POAG was 0.86% among residents aged ≥50 years living in Yongchuan District of Chongqing. The vision loss caused by POAG in this population was obviously higher than that previously reported in other studies. Glaucoma management, detection of affected persons and handling of the burden of glaucoma should be the priorities of the agenda of local health authorities of Western China.

<p><b>OBJECTIVE</b>To compare the effects and pharmacoeconomics of single-dose of ceftriaxone versus 3-day cefuroxime prophylaxis in patients undergoing gastric or colorectal resection.</p><p><b>METHODS</b>Three hundred and five consecutive patients with gastric or colorectal cancer from 5 medical centers were randomly divided into ceftriaxone group (n = 153, receiving intravenously 1 g ceftriaxone 0.5 - 1 h prior to operation only) and cefuroxime group (n = 152, receiving 0.75 g cefuroxime preoperatively and the same dose q8h for 3 d). The patients' intra- and postoperative status, adverse responses and infectious complications were observed and documented, and pharmacoeconomic parameters were analyzed.</p><p><b>RESULTS</b>The disease distribution, operative procedures and patients' conditions in the 2 groups were comparable. No adverse responses to the test antibiotics were observed. Postoperative infectious complications occurred in 7 cases in the ceftriaxone group (4.58%) and 14 cases in the cefuroxime group (9.21%), respectively (P = 0.992), among which, 12 cases were surgical site infections (incisional, intra-abdominal): 2 cases in the ceftriaxone group (1.31%), and 10 cases in the cefuroxime group (6.58%), (chi(2) = 5.607, P = 0.018). The direct cost related to prevention and treatment of surgical site infections was 283.5 RMB in the ceftriaxone group and 811.1 RMB in the cefuroxime group (Z = 14.51, P = 0.000).</p><p><b>CONCLUSION</b>Both ceftriaxone and cefuroxime are safe and effective for prevention of surgical site infections. Single-dose ceftriaxone prophylaxis is sufficient for gastric and colorectal operations, with a better cost-effectiveness ratio.</p>
