BACKGROUND: Mesenchymal stem cells (MSCs) have the abilities of self-renewal, multidirectional differentiation and immunomodulation, and have become the focus of current research. OBJECTIVE: To summarize the immunomodulation of MSCs to different immune cells and the clinical applications of MSCs in the treatment of immune-related diseases. METHODS: The first author searched the PubMed and the CKNI databases for relative articles from January 1974 to December 2016. The key words were mesenchymal stem cells, immunomodulation, MSC1 and MSC2, autoimmune diseases in English and Chinese, respectively. Finally, 52 representative articles were included. RESULTS AND CONCLUSION: MSCs can inhibit the function of T lymphocytes, reduce the activation, proliferation and antibody secretion of B lymphocytes, affect the polarization of macrophages, inhibit the maturation of dendritic cells, inhibit the proliferation and toxicity of NK cells, so MSCs have the great potential in the treatment of immune-related diseases. However, MSCs exhibit the opposite immunomodulatory abilities under different inflammatory microenvironments, and moreover the definite and controllable mechanism of this phenomenon is still unclear, Therefore, future investigations may focus on the specific mechanism of MSCs in the clinical treatment of immune-related diseases.

Objective · To explore ways to improve screening conditions for thyroid disorders during pre-pregnancy period and the first trimester.Methods · 1212 cases of hospitalized expectant mothers from Jan 2016 to Dec 2016 in the First People's Hospital of Lianyungang were studied. As required, these subjects were filled in the questionnaires, including the pregnant women's basic situation, the way of obtaining the information, their understanding level of thyroid disorders, and their experience of thyroid function screening and screening time. The clinical data was analyzed after collected. Results · Among 1212 subjects, merely 214 (17.66%) subjects knew the thyroid disorders and considered it harmful to themselves during their pregnancy, and 659 (54.37%) subjects knew less about thyroid disorders, and 339 (27.97%) knew nothing about the two situations mentioned above.Among all the pregnant women in this study, 29 (2.39%) underwent thyroid function screening before pregnancy, 185 (15.26%) in the first-trimester, 635 (52.39%) during the second and third trimesters, and 363 (29.95%) didn't get thyroid function screening at all. The level of knowing thyroid disorders has a positive correlation to screening ratio in total and the pre-pregnant and first-trimester screening ratio (r=0.57, r=0.15, P=0.000). Conclusion · Raising childbearing-aged women's awareness of thyroid disorders and their harms to pregnancy will be helpful for improving thyroid function screening ratio in pregnancy.

OBJECTIVETo introduce the application of pedicled anterolateral thigh (ALT) flap for total penile reconstruction and to investigate its feasibility and effect.
METHODSFrom May 2011 to May 2015, 12 male patients presented with absence of the penis or congenital malformation received phalloplasty with the pedicled ALT flap. Of them, the median age was 35 years old (range, 20-57 years). The size of the flaps ranged from 11 cm x 11 cm to 12 cm x 15 cm. 8 patients underwent urethra reconstruction with tube-in-tube flaps and other 4 patients with scrotal septal flaps. In this series, we performed one-stage urethral anastomosis in 4 cases and second-stage urethral anastomosis 6 months after the phalloplasty in 8 cases.
RESULTSAn acceptable reconstructed phallus was achieved in 10 patients. These flaps were primarily healed with satisfactory functional and cosmetic results. The reconstructed penis was completely necrosis because of the flap failure in one case. The distal half of the phallus was lost due to infection in one case. Both of them were treated with pedicled ALT flap from the other side. Reliable results were achieved. At a median follow-up of 1.5 year (range 1 to 4 years), 9 patients (90%) were fully satisfied with phallic cosmesis and size, and 4 patients who was married had successful sexual intercourse. 8 patients had normal urinate function. Fistula was developed in 2 patients (20%) which was treated with delayed repair at 6-12 months with local scrotal flaps.
CONCLUSIONSThe pedicled ALT flap can be simply used to reconstruct an entire penis as well as a urethra. It has several advantages including a less conspicuous donor site, greater bulk, better color match and no necessary for microsurgery.

Objective To investigate the values of three-dimensional visualization technology in the diagnosis and surgical treatment of hepatic hemangioma. Methods Thirty two patients with hepatic hemangioma who had been hospitalized during the period from July 2010 to January 2014 in our hospital were scanned by 64-slice spiral computerized tomography (CT) before surgical treatment. Three-dimensional (3D) reconstruction based on the CT data was carried out to achieve dignosis and surgical planning. Assisted with the 3D model , we chose the best surgical procedure for liver resection, protecting the major blood vessels near hemangioma and retaining normal liver tissue as far as possible. Results The location, size and shape of hepatic hemangioma, vascular variation, and spatial relationship with intrahepatic vessel were shown factually by three-dimensional reconstruction. All the hemangiomas were preoperatively assessed to be resectable. The compliance rate for preoperative surgical planning to actual surgery was 100%. Under assistance of the 3D model during surgery , 14 patients received laparoscopic hepatectomy and 18 underwent hepatectomy. Pringle′s maneuver was applied in 18 patients , with blocking time of (15.32 ± 7.12) min and blood loss of (188.63 ± 66.37) mL. The postoperative complications included pleural effusion in 5 patients and incision infection in one patients. Conclusions Three-dimensional visualization technology for the individualized diagnosis and treatment of hepatic hemangioma helps reduce surgical trauma and incidence of postoperative complications.
