Background
The failure to preserve parathyroid function in patients who have undergone total thyroidectomy is of major concern, because hypocalcemia is difficult to prevent and remains a common postoperative complication. Here, we describe procedures designed to preserve the vasculature supplying the parathyroid glands and examine both recent outcomes and retrospective reports of results obtained prior to the application of these preservation techniques.Methods
Our technique for preserving parathyroid function during thyroidectomy was adopted in 2009 and involves separating a relatively long segment of a vessel distally from the thyroid gland. We reviewed the medical records of 1,411 patients who underwent total thyroidectomy, with or without lateral neck dissection, at the Samsung Medical Center from January 2006 through June 2014 to determine outcomes. Patients were divided into three groups according to the time period during which the surgery took place: Group A, 2006–2008 (before the vasculature-preserving technique was applied); Group B, 2009–2011 (the time when the technique was first adopted); and Group C, 2012–2014 (more recent results of the technique). We analyzed the incidence of hypoparathyroidism in the three groups, as well as risk factors that influenced its development.Results
The rates of transient and permanent hypoparathyroidism in Group A were 25.4 and 4.3 %, respectively. However, the incidence of hypoparathyroidism decreased significantly over time after the vasculature-preserving procedure was adopted. Transient hypoparathyroidism developed in 4.8 % of Group C patients, and only four (0.7 %) of the 565 patients in this group required calcium supplementation, despite the fact that a greater number of patients were included who underwent total thyroidectomy combined with lateral neck dissection. Although female sex and lateral neck dissection tended to increase the rate of transient hypoparathyroidism, multivariate analysis showed that the vasculature-preserving procedure was the only significant risk factor related to postoperative hypoparathyroidism.Conclusion
The blood flow of the final branch to the parathyroid gland is mostly in the lateral-to-medial direction; therefore, mobilization and preservation of the vessels lateral to the gland is essential to prevent devascularization of the parathyroid gland.2.

Long non‐coding RNAs (lncRNAs) have been reported to play important roles in cellular metabolism and development. Various diseases have been associated with aberrant expression of lncRNAs and the related dysregulation of mRNAs. An lncRNA profiling assay was carried out to identify the key lncRNA in osteoarthritic human synoviocytes; the results revealed that prostate cancer gene expression marker 1 (PCGEM1) was significantly overexpressed in osteoarthritic synoviocytes. Exogenous overexpression of PCGEM1 inhibited apoptosis, induced autophagy, and stimulated the proliferation of human synoviocytes. The increased expression of PCGEM1 in human synoviocytes also suppressed the expression of miR‐770. Transfection of the miR‐770 precursor resulted in reduced proliferation, and induced apoptosis of human synoviocytes. This effect of miR‐770 expression was reversed by co‐introduction of PCGEM1. Target validation showed a direct binding between PCGEM1 and miR‐770. We demonstrate that PCGEM1 act as sponge lncRNA for miR‐770 that regulates proliferation/apoptosis and autophagy, and suggest PCGEM1 as possible target for OA therapy. © 2015 Orthopaedic Research Society.

Toxicity and target organ distribution of cerium oxide nanoparticles (CeNPs) were investigated via single intravenous injection and single oral administration, respectively. Rats were sacrificed at 24 h after treatment with doses of 30 and 300 mg/kg, and cerium concentrations were measured in liver, kidney, spleen, lung, blood, urine and feces. Results revealed cerium levels in blood and tissues were considerably low in oral treated groups and most cerium was detected in feces, meaning CeNPs would not be absorbed in the gastro-intestinal system. Conversely, high concentrations of cerium were detected in all tissues of rats after intravenous injection. Liver and spleen were main target organs. Cerium levels in liver were 594.9?±?95.3 μg/g tissue in 30 mg/kg treat group and 3741.7?±?932.7 μg/g tissue in 300 mg/kg treat group. Cerium levels in spleen reached almost levels of liver. Cerium was also detected, that is relatively low compared to oral administration, in feces of rats treated via intravenous injection, that supports biliary excretion of CeNPs. Urine excretion of CeNPs was not detected in oral treatment and intravenous injection. In accordance with level of cerium distribution, toxicities based on hematology, serum biochemistry and histopathology were observed in rats treated by intravenous injection while no significance was revealed in orally treated groups. 相似文献

Growth Arrest‐Specific 5 (GAS5) is known to negatively regulate cell survival and is aberrantly expressed in several cancers. The influence of GAS5 on osteoarthritis (OA) has not been determined. To address this, articular chondrocytes were isolated from relatively normal (Non‐OA) and clear OA regions (OA) of cartilage in total knee replacement (TKR) patients and biopsied normal cartilage. We found that GAS5 was up‐regulated in OA chondrocytes compared with Non‐OA and normal chondrocytes. The over‐expression of GAS5 increased the expression levels of several MMPs, such as MMP‐2, MMP‐3, MMP‐9, MMP‐13, and ADAMTS‐4; stimulated apoptosis; and suppressed autophagic responses. Furthermore, we subsequently identified miR‐21 as a regulator of GAS5 during OA pathogenesis. The expression level of miR‐21 was significantly reduced in OA patients, and the ectopic expression of GAS5 is capable of suppressing miR‐21 induction. Consistent with GAS5 experiments, the introduction of miR‐21 stimulated the apoptosis of chondrocytes and inhibited the expression levels of autophagic complexes, including LC‐3B. In vivo, we found that the introduction of miR‐21 into the cartilage of OA mice significantly stimulated cartilage destruction. Together, these results show that GAS5 contributes to the pathogenesis of OA by acting as a negative regulator of miR‐21 and thereby regulating cell survival. © 2014 Orthopaedic Research Society.

BACKGROUND Splenic peliosis is a disease characterized by widespread blood-filled cystic cavities within the parenchyma. Patients with this disease are usually asymptomatic;therefore, spontaneous or trauma-related rupture of the hemorrhagic cysts can occasionally cause life-threatening hemorrhagic shock.CASE SUMMARY A 51-year-old male patient with abdominal pain visited our emergency medical center two times with an interval of 2 mo. The patient was discharged from the hospital without treatment at his first visit;however, at the time of second admission, the hemoperitoneum with multiple cystic lesions of the spleen was found incidentally on the abdomen computed tomography scan. Since the patient was stable hemodynamically, a scheduled surgery was performed. The operative findings were consistent with splenic peliosis, and laparoscopic splenectomy was performed to prevent recurrent rupture of the hemorrhagic cysts.CONCLUSION Splenic peliosis is extremely rare, and we suggest splenectomy is necessarily required as a definite treatment for ruptured splenic peliosis to rescue patients with hemodynamic instability and to prevent recurrent rupture of hemorrhagic cysts in patients with stable hemodynamics. 相似文献

Introduction and hypothesis
The purpose of this study was to evaluate the intra- and postoperative urologic complications and management in patients with cervical or endometrial cancer treated with laparoscopic radical hysterectomy and lymphadenectomy.Methods
We retrospectively reviewed the medical records of 146 patients with cervical or endometrial cancer who underwent total laparoscopic radical hysterectomy with lymphadenectomy between August 2002 and April 2011. The intra- and postoperative urologic complications were analyzed.Results
Double ureteral stents were inserted prophylactically in 13 patients (8.9?%), 2 of whom had postoperative urologic complications. Nine patients (6.2?%) had postoperative urologic complications. Of four patients with ureterovaginal fistulas, two were treated conservatively with cystoscopic placement of ureteral stents and two underwent ureteroneocystostomies. Vesicovaginal fistulas occurred in two patients, both of whom underwent vesicovaginal fistula repairs. One patient noted to have a bladder injury intraoperatively had a laparoscopic repair, and one patient noted to have a ureteral injury postoperatively was treated conservatively with cystoscopic placement of ureteral stents.Conclusions
Iatrogenic lower urinary tract injuries during laparoscopic radical hysterectomy are relatively common complications. Intraoperative prophylactic ureteral stent insertion and the early detection of urologic complications postoperatively is advised for patients who undergo laparoscopic radical hysterectomies. 相似文献8.

HL7 (Health Level 7) is a standard developed for exchanging incompatible healthcare information generated from programs or
devices among heterogenous medical information systems. At present, HL7 is growing as a global standard. However, the HL7
standard does not support effective methods for treating data from various medical sensors, especially from mobile sensors.
As ubiquitous systems are growing, HL7 must communicate with various medical transducers. In the area of sensor fields, IEEE
1451 is a group of standards for controlling transducers and for communicating data from/to various transducers. In this paper,
we present the possibility of interoperability between the two standards, i.e., HL7 and IEEE 1451. After we present a method
to integrate them and show the preliminary results of this approach. 相似文献
