Postoperative acute urinary retention in anorectal diseases treated with acupuncture combined with grain-moxibustion: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the efficacy differences between acupuncture combined with grain-moxibustion and acupuncture on acute urinary retention after epidural anaesthesia for anorectal diseases.@*METHODS@#A total of 60 patients were randomized into an acupuncture combined with grain-moxibustion group and an acupuncture group, 31 cases in each one. In the acupuncture group, acupuncture was applied at Zhongji (CV 3), Guanyuan (CV 4), Qihai (CV 6), Shuidao (ST 28), Pangguangshu (BL 28), Sanyinjiao (SP 6) and Yinlingquan (SP 9). In the acupuncture combined with grain-moxibustion group, grain-moxibustion was given at Zhongji (CV 3), Guanyuan (CV 4), Qihai (CV 6) and Shuidao (ST 28) on the basis of acupuncture. Those who failed to urinate 60 min after the first treatment received the second treatment. 30 min after the second treatment, the lower abdominal symptom scores before and after treatment as well as the bladder residual urine volume after the first urination after treatment were compared between the two groups. In addition, the clinical efficacy and security were evaluated.@*RESULTS@#Compared before treatment, the symptom scores after treatment were reduced in the two groups (<0.05), and the score in the acupuncture combined with grain-moxibustion group was lower than that in the acupuncture group after treatment (<0.05). The bladder residual urine volume in the acupuncture combined with grain-moxibustion group was (26.71±17.01) mL, which was lower than (35.32±20.76) mL in the acupuncture group (<0.05). The total effective rate was 93.5% (29/31) in the acupuncture combined with grain-moxibustion group, which was superior to 71.0% (22/31) in the acupuncture group (<0.05).@*CONCLUSION@#The efficacy of acupuncture combined with grain-moxibustion is superior to simple acupuncture on acute urinary retention after epidural anaesthesia for anorectal diseases, which is safe and reliable.

Yiqi zhuyu decoction combined with FOLFOX-4 as first-line therapy in metastatic colorectal cancer / 中国结合医学杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of yiqi zhuyu decoction (YZD) combined with oxaliplatin plus 5-flurouracil/leucovorin (FOLFOX-4) in the patients with metastatic colorectal cancer (MCRC).</p><p><b>METHODS</b>A total of 120 patients with MCRC were randomly divided into the experimental group (FOLFOX-4 plus YZD, 60 cases) and the control group (FOLFOX-4 plus placebo, 60 cases), according to the sequence of hospitalization from January 2005 to December 2007. The treatment was supposed to be continued until disease progression (PD) or for 48 weeks (i.e., up to 24 cycles of FOLFOX-4). Response rate (RR), progression-free survival (PFS), overall survival (OS) and adverse events (AEs) were observed.</p><p><b>RESULTS</b>RR was 41.5% in the experimental group and 34.0% in the control group [odds ratio (OR): 1.18, 95% CI: 0.77 to 1.82, P=0.432]. Median PFS were 9.0 months and 8.0 months, respectively [hazard ratio (HR): 0.78, 95% CI: 0.53 to 1.15, P=0.215]. Median OS were 21.0 months and 18.0 months (HR: 0.65, 95% CI: 0.43 to 0.99, P=0.043) and grade 3/4 AEs were 56.6% and 76.7% (OR: 0.61, 95% CI: 0.18 to 0.87, P=0.020), respectively.</p><p><b>CONCLUSIONS</b>YZD combined with FOLFOX-4 chemotherapy significantly improved OS in this first-line trial in the patients with MCRC and significantly decreased grade 3/4 AEs. However, RR was not improved, and PFS did not reach statistical significance by the addition of YZD. The treatment of YZD combined with FOLFOX-4 may be necessary in order to optimize efficacy and safety.</p>

Clinical study of external application of Qiyu oil gauze for promoting post-operational healing in patients with anal fistula / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the effects of the external application of Qiyu oil gauze (QYOG) for promoting post-operational healing in patients with anal fistula and to explore its mechanism of action so as to provide a beneficial scientific basis for its wide use.</p><p><b>METHODS</b>Sixty patients with anal fistula scheduled to receive simple low anal fistulectomy were equally assigned, according to the sequence of hospitalization, to the tested group and the control group, and their wounds were classified according to longitudinal diameter into three grades (Grade I with a diameter below 2 cm; Grade II, 2-5 cm; and Grade III, over 5 cm). After the operation was completed and the operational wound was sterilized with benzalkonium bromide, the wound substratum was packed with QYOG in the test group and with vaseline gauze in the control group. The packing gauze was changed every day till the wound was healed. The healing time of the patients was observed, and the number of capillaries and positive cell percentages of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and epidermal growth factor (EGF) in wound granulation tissues were counted on the 5th day after the operation.</p><p><b>RESULTS</b>The wound healing time was 17.80+/-5.46 days in the test group, which was significantly shorter than that in the control group (21.90+/-6.32 days, P<0.01). The number of capillaries and positive cell percentages of VEGF and bFGF in wound granulation tissues on the 5th day in the tested group were higher than those in the control group (P<0.01), though the difference in EGF between the two groups was insignificant (P>0.05).</p><p><b>CONCLUSION</b>QYOG could shorten the wound healing time after anal fistulectomy, which suggests that it participates in the stimulation of wound granulation tissues to produce VEGF and bFGF, and thus promotes capillary genesis and improves blood circulation in wounds so as to promote wound healing.</p>
