Effect of Changji'an Prescription on Intestinal Permeability of IBS-D Rats / 中国实验方剂学杂志

Objective:To observe the effect of Changji'an prescription on intestinal permeability in diarrhea-predominant irritable bowel syndrome (IBS-D) rats and explore its mechanism for treatment of IBS-D. Method:Male SD neonatal rats were randomly divided into five groups:normal group, model group, pinaverium bromide group(0.018 g·kg-1), high-dose(33.48 g·kg-1) and low-dose (16.74 g·kg-1)Changji'an prescription groups. Except for the normal group, the IBS-D model was established by the combination of maternal and infant separation+acetic acid stimulation+restraint stress. After drug treatment, the ultrastructure of rat intestinal mucosa was observed by using transmission electron microscopy and the plasma D-lactate level was detected by enzyme-linked immunosorbent assay (ELISA). The expression levels of tight junction proteins Occludin and Claudin-1 were detected by Western blot. The mRNA expression levels of Occludin,Claudin-1 and zonula occluden(ZO)-1 were detected by real time polymerase chain reaction (Real-time PCR). Result:As compared with the normal group, the intestinal mucosal epithelial cells were damaged in IBS-D model group, and the microvilli arrangement was sparse and tight junction was widened, and some were not obvious,and the plasma D-lactate level in IBS-D rats was increased significantly (PPD-lactate level in pinaverium bromide group and high-dose Changji'an prescription group was significantly decreased (PD-lactate level in the low-dose group Changji'an prescription group had a tendency to decrease with no statistical difference. The mRNA and protein expression levels of Occludin and Claudin-1 and the mRNA expression of ZO-1 in the colon of rats in each administration group were higher than those in the model group (PConclusion:The therapeutic effect of Changji'an prescription on IBS-D may be achieved by improving the intestinal permeability.

Impact of Smoking on Anal Abscess and Anal Fistula Diseases / 中华医学杂志(英文版)

<p><b>Background</b>Several studies have investigated the association between smoking and anal abscess and anal fistula (AA/F) diseases. However, the relationship between cigarette smoking and AA/F remains unclear. This study sought to assess the role of smoking in anorectal male patients in a Chinese population.</p><p><b>Methods</b>In this retrospective study, a questionnaire, including smoking history, was completed over a 3-month period by male inpatients in the Proctology Department of China-Japan Friendship Hospital. "Cases" were patients who had AA/F, and "controls" were patients with other anorectal complaints. Mann-Whitney U-test and Chi-square test were carried out to examine differences in baseline characteristics between groups. Subsequently, multivariate logistic regression was used to explore any related factors.</p><p><b>Results</b>A total of 977 patients aged from 18 to 80 years were included, excluding those diagnosed with inflammatory bowel disease or diabetes mellitus. Out of this total, 805 patients (82.4%) completed the entire questionnaire. Among the 805 patients, 334 (41.5%) were cases and 471 (58.5%) were controls. Results showed significant differences between cases and controls (χ = 205.2, P < 0.001), with smoking found to be associated with the development of AA/F diseases (odds ratio: 12.331, 95% confidence interval: 8.364-18.179, P < 0.001).</p><p><b>Conclusions</b>This study suggested smoking to be a potential risk factor for the development of AA/F diseases in a Chinese population. Consequently, current smoking patients should be informed of this relationship, and further research should be conducted to explore and investigate this further.</p>

Comparing the effect of An's Shaobei Injection (symbols; see text) with Xiaozhiling Injection (symbols; see text) in patients with internal hemorrhoids of grade I-III: a prospective cohort study / 中国结合医学杂志

<p><b>OBJECTIVE</b>To compare the effect of An's Shaobei Injection ([symbols; see text]) with Xiaozhiling Injection ([symbols; see text]) in patients with internal hemorrhoids of grade I-III.</p><p><b>METHODS</b>This cohort study included 1,520 internal hemorrhoids patients with grade I-III who were scheduled for liquid injection treatment from July 2003 to July 2009. The cohort included patients who underwent either An's Shaobei Injection treatment (the treatment group, 760 cases) or Xiaozhiling Injection treatment (the control group, 760 cases). All patients were followed up regularly for 3 years; the observing indices included anal function recovery and clinical response after operation.</p><p><b>RESULTS</b>Among the 1,520 patients, 1,508 (99.2%) completed the 3-year follow-up. The efficacy rate was 97.5% in the treatment group, significantly higher than the control group (91.8%, P<0.01). The recurrence rate in the treatment group was 0.5%, significantly lower than that of the control group (1.3%, P<0.01). In addition, perianal callosity occurred in 8 cases (1.1%) and anorectal stricture in 26 cases (3.5%) after operation in the control group. There was no perianal callosity and anorectal stricture in the treatment group.</p><p><b>CONCLUSION</b>The treatment with An's Shaobei Injection demonstrated superior clinical effect to Xiaozhiling Injection with fewer adverse effects.</p>

Multiple organ dysfunction syndrome due to massive wasp stings: an autopsy case report / 中华医学杂志(英文版)

We reported a case of multiple organ dysfunction syndrome (MODS) following about 300 wasp stings. The diagnosis was based on autopsy findings of acute pulmonary edema, acute kidney injury, hepatic and cardiac dysfunction, and cerebral edema. MODS is a life-threatening complication, and should be considered a possibility after multiple wasp stings. Our autopsy helped to establish the cause of unexpected death due to wasp stings and to elucidate a possible mechanism of MODS.

Clinical result of phacoemulsification after implantation of an apodized diffractive multifocal IOL(Acrysof ReSTOR) / 眼科

Objective To evaluate the visual outcomes,depth of focus and safety after implantation of the Acrysof ReSTOR and the Acrysof Natural.Design Nonrandomized clinical trial.Participant 53 patients with age-related cataract(61 eyes)were divided into two groups:Acrysof ReSTOR group(MIOL)included 28 patients(31 eyes),and reference group-Acrysof Natural group(SIOL)included 25 patients(30 eyes).Method All patients underwent phacoemulsification and IOL implantation.At 1 week,1 month and 3 months postoperatively,distant and near visual acuities were observed,and depth of focus was measured 3 months postoperatively.Main Outcome Measure Uncorrected distant visual acuity(UCDVA),uncorrected near visual acuity(UCNVA),best corrected distant visual acuity(BCDVA),best corrected near visual acuity(BCNVA),distant corrected near visual acuity(DCNVA),depth of focus.Result At 3 months postoperatively,in MIOL group:UCDVA was 0.90?0.15,UCNVA was 0.70?0.19,DCNVA was 0.73?0.21 and depth of focus was 5.5D(+1.5～-4.0D),while in SIOL group:UCDVA was 0.84?0.14,UCNVA was 0.36?0.10,DCNVA was 0.26?0.08 and depth of focus was 2.5D(+1.0～-1.5D).In MIOL group,UCDVA and UCNVA at 1 month were markedly better than those at 1 week. Conclusion Acrysof ReSTOR can provide excellent outcomes both in distants and near visions and it may reduce the dependence on spectacles in near vision.(Ophthalmol CHN,2006,15:344-347)
