Clinical Study on Acupoint Iontophoresis with Sinomenine Hydrochloride in Treating Knee Osteoarthritis / 上海针灸杂志

Objective To observe the clinical efficacy of acupoint iontophoresis with Sinomenine hydrochloride in treating knee osteoarthritis (KOA).Method Sixty KOA patients were randomized into a treatment group and a control group, 30 cases each. The treatment group was intervened by iontophoresis with Sinomenine hydrochloride into specific acupoints via a direct current iontophoresis appliance; the control group was intervened by oral administration of Meloxicam tablets. The Lequesne index, Visual Analogue Scale (VAS) and knee joint space were observed before and after the intervention.Result The Lequesne and VAS scores were significantly changed after the treatment in the two groups (P<0.01,P<0.05). After the intervention, there was a significant difference in the Lequesne score between the two groups (P<0.01). After the treatment, the knee joint space didn't show significant intra-group or between- group differences (P>0.05).Conclusion Acupoint iontophoresis with Sinomenine hydrochloride is an effecttive method in treating KOA.

In vitro and in vivo evaluation of the developed PLGA/HAp/Zein scaffolds for bone-cartilage interface regeneration / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To investigate the effect of electronspun PLGA/HAp/Zein scaffolds on the repair of cartilage defects.</p><p><b>METHODS</b>The PLGA/HAp/Zein composite scaffolds were fabricated by electrospinning method. The physiochemical properties and biocompatibility of the scaffolds were separately characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), and fourier transform infrared spectroscopy (FTIR), human umbilical cord mesenchymal stem cells (hUC-MSCs) culture and animal experiments.</p><p><b>RESULTS</b>The prepared PLGA/HAp/Zein scaffolds showed fibrous structure with homogenous distribution. hUC-MSCs could attach to and grow well on PLGA/HAp/Zein scaffolds, and there was no significant difference between cell proliferation on scaffolds and that without scaffolds (P>0.05). The PLGA/HAp/Zein scaffolds possessed excellent ability to promote in vivo cartilage formation. Moreover, there was a large amount of immature chondrocytes and matrix with cartilage lacuna on PLGA/HAp/Zein scaffolds.</p><p><b>CONCLUSION</b>The data suggest that the PLGA/HAp/Zein scaffolds possess good biocompatibility, which are anticipated to be potentially applied in cartilage tissue engineering and reconstruction.</p>

Prevalence of allergic rhinitis and survey analysis of health service needs and utilization in Qingdao area / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the need and utilization for health services in patients with allergic rhinitis in Qingdao area.</p><p><b>METHODS</b>An investigation was conducted by the method of combining multi-stage sampling and cluster sampling. SPSS 13.0 software was used to analyse the data.</p><p><b>RESULTS</b>Among Two thousand and four hundred questionnaires, two thousand and fifty-two questionnaires were available. The effective rate was 85.5%. The total two-week prevalence in male was 6.5%, while that in female was 6.2%. There was no significant difference between male and female (χ(2) = 0.103, P > 0.05). The total ratio of those who visited doctors was 1.7%. The ratio of those who visited doctors in the first two weeks was 26.7% (35/131). 49.0% of non-users of health service thought it was unnecessary to consult a doctor because of mild symptoms. In the investigation about the allergic rhinitis, 60.2% patients (1235/2052) confessed that they heard of allergic rhinitis, 30.0% patients (616/2052) thought of allergic rhinitis was common cold.</p><p><b>CONCLUSIONS</b>The number of patients treated for allergic rhinitis was less than its prevalence. The primary reason for low attendance was that the majority of patients with mild symptoms thought it was no need to see a doctor. In order to improve the residents' health services utilization, medical education for allergic rhinitis is necessary.</p>

Diagnostic value of combined modified Alvarado scores and computed tomography imaging in the pathological types of acute appendicitis in adults / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To explore the diagnostic value of combined modified Alvarado scores (MAS) and computed tomography imaging in the pathological types of acute appendicitis in adults.</p><p><b>METHODS</b>Clinical data of a total of 396 adult patients with acute appendicitis confirmed by surgery and pathology were analyzed retrospectively from June 2007 to July 2010. Case-control study was used to investigate the MAS. CT signs were studied in 115 patients who underwent preoperative CT scan. Univariable analysis was performed using each indicator among different pathological types. Discriminant classification was formed by applying significant variables identified from univariable analysis and a Fisher discriminant function was created.</p><p><b>RESULTS</b>Twenty three variables were statistically significant among different pathological types after univariable analysis(P<0.05) and were selected for discriminant analysis. Six variables including temperature(X1), leucocyte count(X2), the proportion of neutrophil(X3), MAS points(X4), periappendiceal fat stranding(X5), and extraluminal air(X6) were enrolled. The discriminant function equation was Y1=0.012X1+0.041X2+0.069X3-0.039X4+2.653X5+1.418X6, Y2=0.327X1+0.041X2-0.034X3-0.140X4-1.114X5+2.982X6. The accuracy was 76.5%(88/115) in retrospective assessment and 77.8%(21/27) in prospective assessment.</p><p><b>CONCLUSION</b>The combined use of MAS and CT imaging signs is useful in identifying the pathological types of acute appendicitis in adults, so it is helpful in choosing reasonable therapeutic option for surgeons.</p>

An improved risk of malignancy index in diagnosis of adnexal mass / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>With the advent of color Doppler flow imaging (CDFI) and technological development of detection of serum tumor markers, new opportunities are presented to the improved risk of malignancy index (RMI) based on Jacobs' research for predicting ovarian malignancy in patients with adnexal masses.</p><p><b>METHODS</b>One hundred and eighty women with an adnexal mass admitted for primary laparotomy were studied. Tumor specific growth factor (TSGF) adjusted ultrasound scores and the results of Doppler blood flow analysis were obtained before the operation. Based on the parameters which had been studied in Jacobs' research, TSGF levels and the findings of color Doppler flow imaging, the risk of malignancy model was redesigned using a binary Logistic regression model. The diagnostic efficacy of the improved risk of malignancy index (improved RMI) was compared with the Jacobs' model RMI by receiver operator characteristic (ROC) curve.</p><p><b>RESULTS</b>The ROC curve showed a higher sensitivity (Mcnamer's test, P < 0.05) in the discrimination between benign and malignant adnexal masses for the improved RMI than the RMI. Compared with the RMI, the improved RMI had an advantage in prediction of ovarian germ cell tumors and granular cell tumor (28.57% vs.71.43%, P < 0.05) and the early stage tumors and borderline tumors (33.33% vs. 66.67%, P < 0.05).</p><p><b>CONCLUSION</b>The predictability of the improved RMI is better than the classic Jacobs' model, especially in diagnosis of the ovarian germ cell tumors and granular cell tumor and other early stage adnexal tumors.</p>
