Myositis ossificans circumscripta (MOC) is a kind of self-localized, benign and tumor-like lesions often seen in adults, with approximately 75% of cases caused by trauma. We reported a case of non-traumatic MOC occurred at the elbow joint in a 9-year old child and it has been excised by surgery. After 18 months follow-up, a favorable outcome has been achieved with the Broberg-Morrey score of 100. We suggest that surgical resection should be done as soon as the diagnosis is confirmed.

Background Acute renal failure (ARF) after liver transplantation is associated with high mortality and morbidity. Early therapeutic or preventive intervention is hampered by the lack of early effective prognostic factors. Recent studies indicated that serum levels of cystatin C and β2-microglobulin (132 MG) as well as urinary β2 MG and N-acetyl-β-D- glucosaminidase (NAG) would increase in patients with early and mild renal impairment. In this study, these factors were detected during the different stages in patients who accepted orthotopic liver transplantation (OLT), and their feasibilities to predict early ARF after OLT were also analyzed.Methods Sixty patients with normal blood urea nitrogen (BUN) and serum creatinine (SCr) who received modified piggyback liver transplantation without veno-venous bypass were prospectively studied. Blood samples were drawn from patients for the determination of serum β2 MG(n=60), SCr (n=60) and serum Cystatin C (n=39) at following 5 intervals: before operation (TO), 20 minutes before anhepatic phase (T1), 25 minutes in anhepatic (T2), 60 minutes after repeffusion (T3) and at the end of operation(T4). Urinary β2 MG (n=-60) and NAG (n=60) were also examined at following 3 intervals: before operation (TO), 60 minutes after reperfusion (T3) and at the end of operation (T4). According to the Rimola A criteria of ARF in 24 hours after operation, all the patients were divided into two groups: ARF group and non-ARF group. The data were statistically analyzed to evaluate the feasibiliy of regarding these factors as prognostic factors for early ARF after liver transplantation in patients with normal SCr and BUN before operation.Results Ten of sixty cases showed ARF(16.7%). The Logistic regression analysis showed that the levels of serum and urinary β2 MG as well as serum cystatin C before operation were correlated with early ARF after liver transplantation (P <0.05), while only serum levels of cystatin C and Cr at the end of operation correlated with early ARF (P <0.05, P <0.01) after liver transplantation. The serum β2 MG, Cystatin C, SCr and urinary β2 MG levels in ARF group were much more higher than that in non-ARF group(P<0.05, P<0.01). There were significant differences between the correct and false predictive positive ratios of serum cystatin C, serum and urinary β2 MG levels before operation (P <0.05, P <0.01), while only SCr showed significant difference between these groups at the end of operation (P<0.01).Conclusions The results revealed that there was potential renal damage among those patients who demonstrated normal SCr and BUN before operation, and that liver transplantation could aggravate this damage and causing ARF. Here we provided the prognostic values of serum Cystatin C, β2 MG, urinary β2 MG and NAG in patients with early acute renal failure after liver transplantation.

PURPOSETo investigate the potential correlation between two different types of hip fractures and serum calcium levels.

METHODSWe consecutively studied 101 cases of femoral neck fracture and 95 cases of femoral inter- trochanteric fracture between January 2011 and December 2013. Fasting blood samples were taken and serum calcium measurements were performed respectively in three periods: the time of admission, postoperation, and discharge. Creatinine, alkaline phosphatase and albumin were also analyzed.

RESULTSConsidering the levels of serum calcium between two groups at the time of admission, post- operation and discharge, there was significant difference at admission and discharge (p <0.05), while there was no significant difference at the time of postoperation (p > 0.05). The magnitude of serum calcium fluctuation was larger in femoral neck group than femoral intertrochanteric group. Concerning alkaline phosphatase and albumin levels at admission, there was no significant difference between two groups (p > 0.05).

CONCLUSIONThe capability of reservation and restoration of serum calcium in patients with femoral neck fracture is better than that in patients with femoral intertrochanteric fracture. A low serum calcium level may be susceptible to femoral intertrochanteric fracture.

Objective:To investigate the expression level of NME3 in gastric cancer and its correlation with clinicopathological characteristics and prognosis.Methods:A retrospective case series study was conducted. The clinicopathological data of 156 patients with gastric cancer who received radical gastrectomy in Zhejiang Cancer Hospital between January 2013 and December 2017 were collected. The samples of cancer tissues and paracancerous tissues were taken and partial paracancerous tissues were not meet the standard. Finally, immunohistochemical staining was conducted on both cancer tissues (156 cases) and paracancerous tissues (139 cases) to detect the expression of NME3 protein; H scoring system was used to score the expression of NME3 protein and the patients were divided into NME3 high expression group (H score ≥ 6 points) and NME3 low expression group (H score < 6 points). The clinicopathological characteristics of the 2 groups were analyzed. Kaplan-Meier method was used for overall survival (OS) analysis of the 2 groups, and log-rank test was used for comparison. Univariate and multivariate Cox proportional risk models were used to determine the poor independent factors affecting the poor OS in patients with gastric cancer.Results:The median age of the 156 patients was 61 years (53 years, 68 years), including 110 males (70.5%) and 46 females (29.5%). The proportion of patients with NME3 high expression in cancer tissues was lower than that in paracancerous tissues [51.9% (81/156) vs. 75.5% (105/139)], and the difference was statistically significant ( χ2 = 17.60, P < 0.001). The proportion of patients with NME3 high expression in moderate-low differentiation and moderate differentiation group was lower than that of those in low-differentiation group [63.3% (50/79) vs. 39.4% (28/71)], the proportion of patients with NME3 high expression in pTNM staging group Ⅲ-Ⅳ was higher than that of those in pTNM staging group Ⅰ-Ⅱ [55.5% (76/137) vs. 26.3% (5/19)], and the difference was statistically significant (both P < 0.05). The proportion of patients with NME3 high expression was 62.2% (46/74), 52.0% (13/25), 39.3% (22/56), respectively in patients with Lauran intestinal type, mixed type and diffused type, and the differences were statistically significant ( χ2 = 6.69, P = 0.035). In addition, OS of patients with the NME3 high expression group was better than that of those with the NME3 low expression group, and the difference was statistically significant ( P < 0.001). The further analysis of gender subgroup showed that OS of male patients with the NME3 high expression group was better than that of those with the NME3 low expression group, and OS of female patients with the NME3 high expression group was better than that of those with the NME3 low expression group, and the differences was statistically significant (all P < 0.05). Univariate and multivariate Cox regression analysis showed that the expression of NME3 in cancer tissues (high expression vs. low expression: HR = 0.342, 95% CI: 0.207-0.564, P < 0.001), family history (yes vs. no: HR = 2.240, 95% CI: 1.285-3.907, P = 0.004), pN staging (N 2-3vs. N 0-1: HR = 2.133, 95% CI: 1.114-4.083, P = 0.022), pM staging (M 1vs. M 0: HR = 2.761, 95% CI: 1.386-5.500, P = 0.004), carcinoma embryonic antigen (CEA) level (CEA > 5 ng/ml vs. CEA ≤ 5 ng/ml: HR = 1.688, 95% CI: 1.018-2.798, P = 0.042), carbohydrate antigen 125 (CA125) level (CA125 > 35 U/ml vs. CA125 ≤ 35 U/ml: HR = 2.913, 95% CI: 1.403-6.047, P = 0.004) were independent factors influencing OS in patients with gastric cancer. Conclusions:NME3 is lowly expressed in gastric cancer tissues, and it is highly expressed in higher-differentially, late staged and intestinal type gastric cancer. NME3 low expression is an independent risk factor for the poor prognosis of gastric cancer. It is speculated that NME3 may play a inhibitory role in gastric cancer.

BACKGROUNDAcute renal failure (ARF) after liver transplantation is associated with high mortality and morbidity. Early therapeutic or preventive intervention is hampered by the lack of early effective prognostic factors. Recent studies indicated that serum levels of cystatin C and beta2-microglobulin (beta2 MG) as well as urinary beta2 MG and N-acetyl-beta-D-glucosaminidase (NAG) would increase in patients with early and mild renal impairment. In this study, these factors were detected during the different stages in patients who accepted orthotopic liver transplantation (OLT), and their feasibilities to predict early ARF after OLT were also analyzed.

METHODSSixty patients with normal blood urea nitrogen (BUN) and serum creatinine (SCr) who received modified piggyback liver transplantation without veno-venous bypass were prospectively studied. Blood samples were drawn from patients for the determination of serum beta2 MG (n = 60), SCr (n = 60) and serum Cystatin C (n = 39) at following 5 intervals: before operation (T0), 20 minutes before anhepatic phase (T1), 25 minutes in anhepatic (T2), 60 minutes after reperfusion (T3) and at the end of operation (T4). Urinary beta2 MG (n = 60) and NAG (n = 60) were also examined at following 3 intervals: before operation (T0), 60 minutes after reperfusion (T3) and at the end of operation (T4). According to the Rimola A criteria of ARF in 24 hours after operation, all the patients were divided into two groups: ARF group and non-ARF group. The data were statistically analyzed to evaluate the feasibiliy of regarding these factors as prognostic factors for early ARF after liver transplantation in patients with normal SCr and BUN before operation.

RESULTSTen of sixty cases showed ARF (16.7%). The Logistic regression analysis showed that the levels of serum and urinary beta2 MG as well as serum cystatin C before operation were correlated with early ARF after liver transplantation (P < 0.05), while only serum levels of cystatin C and Cr at the end of operation correlated with early ARF (P < 0.05, P < 0.01) after liver transplantation. The serum beta2 MG, Cystatin C, SCr and urinary beta2 MG levels in ARF group were much more higher than that in non-ARF group (P < 0.05, P < 0.01). There were significant differences between the correct and false predictive positive ratios of serum cystatin C, serum and urinary beta2 MG levels before operation (P < 0.05, P < 0.01), while only SCr showed significant difference between these groups at the end of operation (P < 0.01).

CONCLUSIONSThe results revealed that there was potential renal damage among those patients who demonstrated normal SCr and BUN before operation, and that liver transplantation could aggravate this damage and causing ARF. Here we provided the prognostic values of serum Cystatin C, beta2 MG, urinary beta2 MG and NAG in patients with early acute renal failure after liver transplantation.

OBJECTIVETo evaluate the safety and effectiveness of endourological techniques in the treatment of benign prostate hyperplasia (BPH) in aged high-risk patients.

METHODSWe used endourological techniques in the treatment of 283 BPH patients aged over 70 years and complicated with hydronephrosis, renal failure, heart failure, cerebral infarction, respiratory dysfunction, anemia, diabetes, bladder tumor, or prostate weight over 80 g, TURP (transurethral resection of the prostate) for 112 cases and PKRP (transurethral plasmakinetic resection of the prostate) for the other 171. All the patients were followed up for 1-30 months.

RESULTSIn the TURP group, the scores on IPSS and QOL were decreased from 27.5 +/- 2.8, 5.5 +/- 1.0 to 5.8 +/- 1.2, 1.0 +/- 0.5, and the residual urine volume (RUV) from (75.0 +/- 20.0) ml to (8.0 +/- 3.0) ml, but the maximal flow rate (Qmax) increased from (6.5 +/- 2.0) ml/s to (18.5 +/- 1.5) ml/s (P < 0.05), while in the PKRP group, the scores on IPSS and QOL were decreased from 28.2 +/- 2.2, 5.5 +/- 1.0 to 5.4 +/- 1.6, 1.0 +/- 0.5, and RUV from (80.0 +/- 20.0) ml to (7.0 +/- 3.0) ml, and Qmax increased from (6.8 +/- 2.1) ml/s to (20.0 +/- 1.5) ml/s (P < 0.05). There were no statistically significant differences in IPSS, QOL, Qmax and RUV after treatment between the two groups (P > 0.05), but significantly less complications were found in the PKRP than in the TURP group (P < 0.05).

CONCLUSIONEndourological treatment, especially PKRP, with comprehensive perioperative preparations, unerring operative skills, well-controlled operation time, and intensive postoperative monitoring and nursing, has the advantages of high safety, less bleeding, fewer complications and definite effectiveness for aged high-risk BPH patients.

OBJECTIVE: To assess the performance of a high-definition CT (HDCT) for imaging small caliber coronary stents (< or = 3 mm) by comparing different scan modes of a conventional 64-row standard-definition CT (SDCT). MATERIALS AND METHODS: A cardiac phantom with twelve stents (2.5 mm and 3.0 mm in diameter) was scanned by HDCT and SDCT. The scan modes were retrospective electrocardiography (ECG)-gated helical and prospective ECG-triggered axial with tube voltages of 120 kVp and 100 kVp, respectively. The inner stent diameters (ISD) and the in-stent attenuation value (AVin-stent) and the in-vessel extra-stent attenuation value (AVin-vessel) were measured by two observers. The artificial lumen narrowing (ALN = [ISD - ISDmeasured]/ISD) and artificial attenuation increase between in-stent and in-vessel (AAI = AVin-stent - AVin-vessel) were calculated. All data was analyzed by intraclass correlation and ANOVA-test. RESULTS: The correlation coefficient of ISD, AVin-vessel and AVin-stent between the two observers was good. The ALNs of HDCT were statistically lower than that of SDCT (30 +/- 5.7% versus 35 +/- 5.4%, p < 0.05). HDCT had statistically lower AAI values than SDCT (15.7 +/- 81.4 HU versus 71.4 +/- 90.5 HU, p < 0.05). The prospective axial dataset demonstrated smaller ALN than the retrospective helical dataset on both HDCT and SDCT (p < 0.05). Additionally, there were no differences in ALN between the 120 kVp and 100 kVp tube voltages on HDCT (p = 0.05). CONCLUSION: High-definition CT helps improve measurement accuracy for imaging coronary stents compared to SDCT. HDCT with 100 kVp and the prospective ECG-triggered axial technique, with a lower radiation dose than 120 kVp application, may be advantageous in evaluating coronary stents with smaller calibers (< or = 3 mm).
