Objective To investigate the clinical features of hidden horizontal tears of the posterior horn of the medial meniscus and clinical efficacy of arthroscopic partical meniscectomy. Methods A total of 14 cases of hidden horizontal tears of posterior horn of the medial meniscus from May 2011 to May 2013 were enrolled.The knee arthroscopy was carried out through anteromedial and anterolateral approaches.The lesion of tears was exposed after the inner edge of posterior horn of the meniscus was bitten away.The bottom of the posterior horn of meniscus was found instable during the operation, which was then removed to conduct a partial meniscectomy.Afterwards the arthroscopic meniscus plasty of the posterior horn was performed. Results Arthroscopic photographs showed normal appearance in 6 cases and tears underside meniscus in 8 cases, all of which were confirmed to be horizontal medial meniscus posterior horn tear during operation.The mean time of operation was 32 min (range, 26-40 min), and the mean hospitalization time was 6 days ( range, 3-8 d) .There was no complications, such as infections or stiffnesses.All the patients were followed up for 2 -3 years.Subjective symptoms improved significantly after arthroscopic partial meniscectomy.According to the Lysholm knee scoring scale, the scores were (71.1 ±6.6) points preoperatively and (92.0 ±3.4) points postoperatively, with significant difference (t=10.530, P=0.000). Conclusion Diagnosis of hidden horizontal tears of the medial meniscus posterior horn is often difficult, because most patients have osteoarthritic knees.Careful physical examination and MRI are critical for making a correct diagnosis.Arthroscopic partial meniscectomy can help patients obtain better results.

Objective To observe the effects of low frequency electromagnetic fields (LFEMFs) on the proliferation of human epidermal stem cells (hESCs) cultured in a three dimensional environment so as to provide an experimental basis for applying LFEMF in skin tissue engineering.Methods hESCs from human prepuces were isolated and purified by the method of rapid adherence to collagen type ⅣV. They were grafted into a type-I collagen sponge or chitosan scaffold in vitro, and then stimulated with different frequencies of LFEMF ( 1 Hz, 10 Hz or 50 Hz) at a magnetic field intensity of 5 mT for 30 min/d. The cells' growth and proliferation were tracked using hematoxylin and eosin (HE) and diamine pheny1 indole (DAPI) staining and observed under the scanning electron microscope at different time points ( on 2nd, 7th, 10th and 14th days of LFEMF intervention). The amounts of cell proliferation at every time point were analyzed and compared.Results LFEMFs of different frequencies showed significantly different efficacy in promoting hESC proliferation. The two scaffolds also showed significantly different effects.By the 10th day, hESCs had grown significantly better on collagen sponge scaffolds than on the chitosan ones. All LFEMF frequencies could promote proliferation of hESCs, but the differences in their effects were statistically significant.Conclusion Collagen sponge may be a preferable scaffold for hESCs cultured in vitro. Rapid proliferation of ESCs in three-dimensional settings can be promoted by LFEMF intervention. LFEMF has relatively great potential in skin tissue engineering.

Objective To investigate the prognosis and prognostic risk factors of hepatic artery complications after orthotopic liver transplantation (OLT) treated with the interventional techniques.Methods The clinical data of 21 patients with hepatic artery complication after liver transplantation receiving thrombolysis, PTA, and stent placement in our institute from November 2003 to April 2007 were retrospectively analyzed. Based on the prognosis of grafts, 21 patients were divided into poor-prognosis group and non-poor-prognosis group. Fifteen variables (including biliary complication, hepatic artery restenosis,early or late artery complication, and so on) were analyzed in both groups with binary logistic regression analysis to screen out the risk factors related to prognosis of percutaneous interventional treatment for hepatic artery complications after OLT. Results Twenty-one patients were followed for mean 436 days, median 464 days (3-1037 days). The poor-prognosis group included 11 patients (5 cases received retransplantation, and 6 died). The mean survival time of grafts in poor-prognosis group was 191 days, and median survival time was 73 days (3-616 days). The mean survival time of grafts in non-poor-prognosis group which included 10 patients was 706 days, and median survival time was 692 days (245-1037 days).Univariate analysis showed there were significant difference in biliary complication, total bilirubin and indirect bilirubin between the two groups. The binary logistic regression analysis showed the risk factor related to prognosis was with biliary complication before the interventional management (P = 0.027, OR =22.818). Conclusion Biliary complication before interventional management is the risk factor related to poor prognosis of patients with hepatic artery stenosis or thrombisis receiving interventional treatment.

Objective To summarize the experience of reconstruction of Ⅴ and Ⅷ hepatic veins in right lobe (without middle hepatic vein) living donor liver transplantation. Methods The clinical data of 55 cases of living donor liver transplantation of right lobe without middle hepatic vein were analyzed, and Ⅴ and Ⅷ hepatic veins were reconstructed. All donors underwent evaluation on the basis of vascular anatomy, GRWR and graft volume/ESLV. Fifty-one grafts underwent reconstruction of Ⅴ and Ⅷ hepatic veins with cold-storage cadaveric iliac veins. Great saphenous vein, varicose umbilical veins, recipient intrahepatic portal veins and recipient intrahepatic veins were used respectively in the remaining 4 cases. Results One recipient died of obstruction of out-flow on the postoperative day 43. One recipient was converted to cadaver donor liver transplantation at the 7th day after operation, because of acute liver function failure. The remaining 53 cases recovered successfully. Conclusion Reconstruction of Ⅴ and Ⅷ hepatic veins with proper materials in right lobe (without middle hepatic vein) living donor liver transplantation is feasible, and the effect is satisfactory.

Objective To evaluate the therapeutic effect of transarterial chemoembolization (TACE) combined with CT-guided 125I seed implantation in treating hepatocellular carcinoma (HCC) complicated by portal vein tumor thrombus(PVTT), and to discuss the technical points. Methods A total of 48 HCC patients with PVTT were enrolled in this study. TACE combined with CT-guided 125I seed implantation was carried out in all 48 patients. Based on the sites of PVTT, the lesions were classified into type A (PVTT within main portal vein), type B(PVTT within level-1 portal branch) and type C(PVTT within level-2 or more distal portal branch). According to whether the 125I seeds were directly implanted into the PVTT or not, the patients were divided into direct in-tumor thrombus implantation group (group A) and around tumor thrombus implantation group (group B; the 125I seeds were implanted in the liver parenchyma or in tumor tissue around the tumor thrombus within 1.7 cm region). The tumor thrombus control rate(TTCR), the disease control rate(DCR), the time to progress(TTP) and the overall survival rate of patients(OS) were determined, and the results were compared among different types and groups. Results TACE combined with CT-guided 125I seed implantation was successfully accomplished in all 48 patients. The median OS of type A, B and C was 8, 11.5 and 15 months respectively(P=0.003);the TTCR of type A, B and C was 61.5%, 70.8%and 72.7%respectively(P=0.548); the DCR of type A, B and C was 69.2%, 75%and 81.8% respectively (P=0.483); the median TTP of type A, B and C was 4.5, 8 and 11 months respectively(P=0.030);the median TTP of intra-hepatic tumor of type A, B and C was 5, 9 and 9.5 months respectively(P=0.012). The median OS in group A and group B was 10 and 11.5 months respectively (P=0.239); the TTCR in group A and group B was 69.2% and 68.2%respectively(P=0.591); the DCR of intra-hepatic tumor in group A and group B was 73.1% and 77.3%respectively(P=0.502); the median TTP of tumor thrombus in group A and group B was 7 and 10 months respectively(P=0.276); and the median TTP of intra-hepatic tumor in group A and group B was 8 and 9.5 months respectively(P=0.089). Conclusion For the treatment of hepatocellular carcinoma complicated by portal vein tumor thrombus, TACE combined with CT-guided 125I seed implantation can effectively control the progress of both the tumor thrombus and the intra- hepatic tumor and prolong patient’s survival time. Implantation of 125I seeds into the portal vein tumor thrombus and implantation of 125I seeds into the liver parenchyma around the tumor thrombus have the same therapeutic results.

Objective To observe the effects of low intensity electromagnetic fields (LIEMFs) in promoting the reconstruction of full skin loss wounds grafted with human epidermal stem cells (ESCs). Methods Fifty nude mice aged 7 to 8 weeks with full skin loss wounds were equally divided into 3 experimental subgroups ( 1 Hz, 10Hz and 50Hz) and two control groups (a cell suspension control group and a blank control group) , with ten mice each. In the 3 experimental subgroups and the cell suspension control group, ESCs separated from human foreskin and cultured in vitro were grafted to the wounds using collagen sponge scaffolds. The experimental subgroups were then stimulated with an LIEMF (magnetic field intensity 5mT) at the appropriate frequency for 30min/day for 15 days. The blank control group was put under the same conditions without the cell suspension and LIEMF. The healing rates of the wounds were observed, and tissue slices were stained and observed under a light microscope. The inner structure of the regenerating skin was observed using transmission electron microscopy. Results The ESCs were successfully grafted. A few human integrin β1 positive stained cells appeared in the regenerating skin. The average healing rates in the experimental subgroups were significantly superior to those of the control groups. Well differentiated epidermis and dermis could be seen in the regenerating skin in all of the experimental groups. The epidermis had more cell layers and was thicker than in the control groups. More desmosome, hemidesmosome and keratin filaments were seen among the epidemic cells of the experimental groups. Conclusions LIEMF promotes the healing of full skin loss wounds grafted with ESCs in nude mice, and can promote complete repair of skin defects and the regeneration of skin function.
