Objective: To observe the efficacy of mild moxibustion combined with arthroscopic meniscal repair in the treatment of meniscal injury and to explore its action mechanism. Methods: Ninety-eight patients with meniscal injury were divided into a surgery group and a moxibustion plus surgery group by the random number table method, with 49 cases in each group. Both groups received arthroscopic meniscal repair, and the moxibustion plus surgery group was treated with add-on mild moxibustion. The Lysholm score, visual analog scale (VAS) score, and mobility of the affected knee were measured before and after treatment, and transforming growth factor (TGF)-β1 and platelet-derived growth factor (PDGF) levels were measured in the fluid of the affected knee joint. The healing of the meniscus was recorded at a follow-up visit 3 months after the surgery. Results: After treatment, the Lysholm score increased, the VAS score decreased in both groups, and the intra-group differences in both groups were statistically significant (P<0.05). The Lysholm score was higher in the moxibustion plus surgery group than in the surgery group, and the VAS score was lower in the moxibustion plus surgery group than in the surgery group. The differences between groups in both scores were statistically significant (P<0.05). The mobility of the affected knee joint increased in both groups (P<0.05), and it was greater in the moxibustion plus surgery group than in the surgery group (P<0.05). When compared with pretreatment, the levels of TGF-β1 and PDGF in the fluid of the knee joint increased in both groups (P<0.05), and the levels of TGF-β1 and PDGF in the fluid of the affected knee joint were higher in the moxibustion plus surgery group than in the surgery group (P<0.05). The healing of the meniscus in the moxibustion plus surgery group was significantly better than that in the surgery group at the follow-up visit 3 months after the surgery (P<0.05). Conclusion: The effect of mild moxibustion combined with arthroscopic meniscal repair is better than the surgery alone in improving knee function, relieving pain, increasing mobility of the affected knee, and promoting meniscal healing, which may be related to the up-regulation of TGF-β1 and PDGF levels in the fluid of knee joint.

Objective To explore the value of contrast-enhanced ultrasound (CEUS) in the differential diagnosis of subserous myoma (SM) and ovarian fibroma.Methods CEUS was performed on 58 patients with SM and 26 patients with ovarian fibroma.The enhancement pattern was observed.The diagnostic performance was evaluated by using diagnostic test.Results SM exhibited homogeneous isoenhancement synchronously with the myometrium in early phase.In the late phase,the pseudocapsule remained hyper-enhancement with obvious membraniform sign.Some myomas showed the feeding artery from uterus.Ovarian fibroma demonstrated hyper-enhancement at the periphery portion and hypoenhancement inside.Conclusions The SM and ovarian myomas showed different enhancement patterns,which may provide us some exact information in the differential diagnosis between the two diseases.

ObjectiveTo assess the diagnostic performance of contrast-enhanced ultrasound(CEUS)in characterization of adnexal masses in comparison with baseline ultrasound.MethodsOne hundred and thirty-seven masses were examined by CEUS and baseline ultrasound.Two independent investigators reviewed the images before and after contrast agent administration.The diagnostic performances were evaluated using receiver operating characteristic (ROC) analysis and the interobserver agreement was analyzed.ResultsAfter review of CEUS,ROC analysis revealed significant improvement in differentiating between malignant and benign pelvic masses that the areas under the ROC curve were 0.731 and 0.738 at baseline ultrasound versus 0.891 and 0.903 at CEUS ( P ＜0.01 ).The accuracy for both investigators also improved significantly after reviewing CEUS.A better interobserver agreement was achieved after reviewing of CEUS (g =0.681 at baseline ultrasound versus κ =0.893 at CEUS) and a better result of specific diagnosis was obtained (73.2％ and 74.2％ at baseline ultrasound versus 90.7％ and 91.2％ at CEUS)(all P ＜ 0.01 ).Conclusions Real-time CEUS improves the diagnostic performance in adnexal masses for discrimination between malignancy and benignity and improves the capability in specific diagnosis compared with baseline ultrasound.

Objective To assess the diagnostic performance of contrast-enhanced ultrasound in characterization of pelvic masses.Methods Contrast-enhanced ultrasound was performed on 137 patients with pelvic masses.The results were compared to pathological diagnostic criteria.The diagnostic performance was evaluated by using diagnostic test.Results Sensitivity,specificity,positive predictive value,negative predictive value,accuracy and area under ROC curve in diagnosing complex pelvic masses by using contrast-enhanced ultrasound were as follows:85.3％ (29/34),93.2％ (96/103),80.6％ (29/36),95.0％ ( 99/101 ),91.2％ ( 125/137 ),0.892,respectively.Conclusions Contrast-enhanced ultrasound provides a simple and curate method for characterization of pelvic masses.

Objective To explore the value of contrast-enhanced ultrasound(CEUS)in the differential diagnosis of endometrial carcinoma and endometrial hyperplasia.Methods Forty-five patients with endometrial carcinoma and 21 patients with hyperplasia were studied by CEUS.Twenty-four normal women were enrolled as contrast group.Results In normal uterus, myometrium exhibited earlier enhancement later washout than the endometrium.Similar phenomenon was observed in patients with hyperplasia.In patients with endometrial carcinoma,the lesion showed wash-in and washout earlier, at least not later than the myometrium.Conclusions Endometrial carcinoma and hyperplasia showed different enhancement patterns,which may be helpful for the diagnosis of the two diseases.

Objective To explore the effect of general intervention in improving the psychological condition of healthy pregnant women. Methods Totally 96 pregnant women who made prenatal visits in our obstetrics and outpatient department were divided into the control and the intervention group stochasti-cally. The intervention group started from first prenatal visit. The general intervention measures included cognitive intervention, the behavioral intervention, family coping intervention and psychological intervention with self-designed relaxation exercises. While conventional prenatal visit, propaganda and nursing were im-plemented to the control group.Self-made general questionnaire and symptom checklist 90 (SCL-90)were used to survey and analyze the results. Results Post-natal depression and anxiety of the control group was obviously higher than that of the prenatal. The Post-natal obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility, terror and bigotry in the intervention group were greatly alleviated. Com-pared with the control group, obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility and terror of the intervention group were significantly different (P<0.05). The depression improved while the difference was not evidently differenL Conclusions Delivery had great influence on the psychological status of women,especially anxiety and depression. General intervention measures like psychological relax-ation exercises can improve the psychological condition of healthy pregnant women obviously,especially de-pression.

Vibrios are universal conditioned-pathogenic bacteria in marine culture environment, and the outbreak of vibrio disease resulted in a serious damage to aquaculture. Considering that vibrio disease in aquatic species, especially fishes, usually originated from mixed infection of different species (serotypes or subspecies) of vibrios, it is important to select the potential cross-protective protein antigens as candidates of polyvalent or combined vaccines. In present research, several strains of vibrios were isolated from infected large yellow croaker (Pseudosciaena crocea) and subsequently identified as six strains of V. harveyi, one V. parahaemolyticus and one V. alginolyticus by physiological, biochemical and molecular biological methods. Their outer membrane proteins (OMPs) were extracted and the SDS-PAGE and Western blotting results show that three immuno-blots with common molecular weight presented at approximate 45 kDa, 35 kDa and 22 kDa on their OMP electrophoretogram, indicating the existence of antigens with cross-protection in their OMPs. With the aids of combination of two-dimensional electrophoresis (2-D) and Western blotting and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS), a deduced porin (GenBank Accession No. ZP_01260407) from V. alginolyticus and a maltoporin precursor (GenBank Accession No. NP_801154) from V. parahaemolyticus were able to react with polyclonal antibody to whole V. harveyi, suggesting these two proteins could act as the cross-protective antigens and the vaccines prepared with these porins would be probable to bring cross protection to three different vibrios.
