Abstract
Objective: To compare the cerebral perfusion differences between the symptomatic patients and the asymptomatic patients with unilateral middle cerebral artery (MCA) severe stenosis or occlusion by using three post labeling delays (PLD) of the three-dimensional pseudo-continuous arterial spin labeling (pCASL) technique. Methods: The clinical characteristics and ASL data of the 27 patients with severe stenosis or occlusion of unilateral MCA (18 symptomatic, 9 asymptomatic) were prospectively enrolled from April 2018 to November 2019 in the Department of Radiology of China-Japan Friendship Hospital. There were 16 males and 11 females, age range from 29 to 85 (55±13) years. According to the symptoms, they were divided into symptomatic group (18 cases) and asymptomatic group (9 cases). The parameters of cerebral blood flow (CBF), mean cerebral blood flow (mCBF), arterial transit time (ATT) and arterial cerebral blood volume (aCBV) were obtained using the Cereflow software. One-way multivariate analysis of variance (one-way MANOVA) was used to compare the differences of cerebral perfusion parameters between symptomatic group and asymptomatic group, and between the affected side and the control side in the two groups. Two-way ANOVA was used to evaluate the effects of symptoms, hemisphere (affected and control side), PLD times (1.5, 2.0 and 2.5 s) and the interaction between the two factors. Results: The CBF of the affected leptomeningeal branch and perforating branch of MCA in symptomatic group was lower than that in asymptomatic group [(36.8±10.2) ml·100 g-1·min-1 versus (46.6±13.9) ml·100 g-1·min-1, F(1, 75)=13.279, P=0.000 49; (32.3±8.3) ml·100 g-1·min-1 versus (36.2±7.5) ml·100 g-1·min-1, F (1, 75)=4.065, P=0.047], and there was no interaction between the symptom and PLD [F(2, 75) =0.061, P=0.940]. In the symptomatic group, the CBF of the leptomeningeal branch and perforating branch of MCA in affected side was lower than that in control side [(36.8±10.2) ml·100 g-1·min-1 versus (43.7±10.0) ml·100 g-1·min-1, F(1, 102)=12.559, P=0.000 59; (32.3±8.3) ml·100 g-1·min-1 versus (36.4±8.0) ml·100 g-1·min-1, F(1, 102)=6.493, P=0.012]. In the symptomatic group, the CBF of leptomeningeal branch of MCA when PLD was 2.5 s was 7.34 ml·100 g-1·min-1, which were higher than that when PLD of 1.5 s (95%CI: 0.72-13.9, P=0.03). There was no interaction between PLD and hemisphere [F(2, 102) =0.307, P=0.736]. Conclusions: The collateral circulation in the blood supply area of MCA in asymptomatic patients with severe unilateral MCA stenosis or occlusion is more abundant than that in symptomatic patients. ASL can be an effective technique for evaluating the cerebral perfusion of collateral circulation in patients with severe stenosis or occlusion of MCA.

Abstract
BACKGROUND Due to the phenotypic and molecular diversity of hepatocellular carcinomas (HCC), it is still a challenge to determine patients' prognosis. We aim to identify new prognostic markers for resected HCC patients. METHODS 274 patients were retrospectively identified and samples collected from Zhongshan hospital, Fudan University. We analyzed the gene expression patterns of tumors and compared expression patterns with patient survival times. We identified a "9-gene signature" associated with survival by using the coefficient and regression formula of multivariate Cox model. This molecular signature was then validated in three patients cohorts from internal cohort (n = 69), TCGA (n = 369) and GEO dataset (n = 80). RESULTS We identified 9-gene signature consisting of ZC2HC1A, MARCKSL1, PTGS1, CDKN2B, CLEC10A, PRDX3, PRKCH, MPEG1 and LMO2. The 9-gene signature was used, combined with clinical parameters, to fit a multivariable Cox model to the training cohort (concordance index, ci = 0.85), which was successfully validated (ci = 0.86 for internal cohort; ci = 0.78 for in silico cohort). The signature showed improved performance compared with clinical parameters alone (ci = 0.70). Furthermore, the signature predicted patient prognosis than previous gene signatures more accurately. It was also used to stratify early-stage, HBV or HCV-infected patients into low and high-risk groups, leading to significant differences in survival in training and validation (P < 0.001). CONCLUSIONS The 9-gene signature, in which four were upregulated (ZC2HC1A, MARCKSL1, PTGS1, CDKN2B) and five (CLEC10A, PRDX3, PRKCH, MPEG1, LMO2) were downregulated in HCC with poor prognosis, stratified HCC patients into low and high risk group significantly in different clinical settings, including receiving adjuvant transarterial chemoembolization and especially in early stage disease. This new signature should be validated in prospective studies to stratify patients in clinical decisions.

Abstract
Inflammation has a critical role in the development and progression of cancers. We developed a novel systemic inflammation score (SIS) based on lymphocyte, monocyte, and CA19-9 and explored its prognostic value in intrahepatic cholangiocarcinoma (ICC). From January 2005 to December 2011, 322 consecutive ICC patients who underwent curative resection in our center were included in this study, and validated in a retrospective study of 126 patients enrolled from 2012 to 2014. Clinicopathological variables including preoperative serum CA19-9 and LMR were analyzed. The cutoff values of CA19-9 and LMR were determined based on receiver operating characteristics curve analysis in the primary cohort. Kaplan-Meier curves and multivariate Cox-regression analyses were calculated for time to recurrence (TTR) and overall survival (OS). In univariate analysis of all patients, all three inflammatory and tumor marker including NLR ≥ 2.49 (P<0.001), LMR ≤ 4.45 (P=0.002), and CA19-9≥89 (P<0.001) were associated with poor prognoses. When omitting SIS in multivariate analysis, preoperative LMR (P =0.006) and serum CA19-9 (P<0.001) were independent predictors of OS. In addition, elevated CA19-9 (P=0.001), multiple tumors (P<0.001), and lymph node metastasis (P<0.001) were significant predictors of worse recurrence free survival. Moreover, high SIS was significantly associated with aggressive tumor behaviours including large tumor size (P<0.001), multiple tumors (P=0.033), lymphonodus node metastasis (P=0.001), and high TNM stage (P<0.0001). Finally, univariate and multivariate analyses revealed the SIS was an independent predictor for TTR (HR=2.077, 95% CI, 1.365-3.162, P=0.001) and OS (HR=3.133 95% CI, 2.058-4.769, P<0.001). These results were further confirmed in the validation cohort. In conclusions, our findings demonstrate that the SIS as a potentially powerful prognostic biomarker in ICC that predicts poor clinical outcomes and is a promising tool for ICC treatment strategy decisions.

Abstract
Objective: To analyze the clinical features and imaging characteristics of Meniere's disease (MD)verified by intravenous gadolinium contrast-enhanced magnetic resonance imaging(MRI). Methods: A total of 174 patients with Meniere's disease were involved in this study between March 2016 and October 2017. All of them underwent 3D-fluid attenuated inversion recovery (FLAIR) MRI and presented endolymphatic hydrops and clinical characteristics of suspected Meniere's disease. The clinical characteristics, the grades of endolymphatic hydrops (EH) using Nakashima grading standard were analyzed, and the correlation between grade and clinical features was evaluated. Results: There were totally 174 patients (88 males, 86 females), with the age of 7-83 years [mean age of (51.0±15.0)] years. Age of onset and disease course was 7-83 years [mean age of (44.6±16.6) years], 36.0 (12.0, 111.0) months (from 2 days to 70 years), respectively. EH was found in all the patients, and 169 cases (97.1%) manifested as modest or severe hydrops. Among the 174 patients, 139 cases (79.9%) presented unilateral EH, and 35 cases (20.1%) presented bilateral EH. The degree of EH in the latter was more serious than the former. For 174 patients, clinical characteristics were inconsistent, which was not in accord with the existing diagnostic criteria. Furthermore, there was a correlation between degree of hydrops and degree of hearing loss (P<0.05). Conclusions: EH in Meniere's disease can be measured objectively by intravenous gadolinium contrast-enhanced MRI. Clinical characteristics in MD verified by EH are not accordant with the existing criteria, which means the significance of EH in diagnosis of MD. Moreover, there's a correlation between degree and distribution of hydrops and degree of hearing loss.

Abstract
PURPOSE While abdominal compression (AC) can be used to reduce respiratory liver motion in patients receiving helical tomotherapy for hepatocellular carcinoma, the nature and extent of this effect is not well described. The purpose of this study was to evaluate the changes in magnitude of three-dimensional liver motion with abdominal compression using four-dimensional (4D) computed tomography (CT) images of several plate positions. METHODS From January 2012 to October 2015, 72 patients with intrahepatic carcinoma and divided into four groups underwent 4D-CT scans to assess respiratory liver motion. Of the 72 patients, 19 underwent abdominal compression of the cephalic area between the subxiphoid and umbilicus (group A), 16 underwent abdominal compression of the caudal region between the subxiphoid area and the umbilicus (group B), 11 patients underwent abdominal compression of the caudal umbilicus (group C), and 26 patients remained free breathing (group D). 4D-CT images were sorted into ten-image series, according to the respiratory phase from the end inspiration to the end expiration, and then transferred to treatment planning software. All liver contours were drawn by a single physician and confirmed by a second physician. Liver relative coordinates were automatically generated to calculate the liver respiratory motion in different axial directions to compile the 10 ten contours into a single composite image. Differences in respiratory liver motion were assessed with a one-way analysis of variance test of significance. RESULTS The average respiratory liver motion in the Y axial direction was 4.53 ± 1.16, 7.56 ± 1.30, 9.95 ± 2.32, and 9.53 ± 2.62 mm in groups A, B, C, and D, respectively, with a significant change among the four groups (p < 0.001). Abdominal compression was most effective in group A (compression plate on the subxiphoid area), with liver displacement being 2.53 ± 0.93, 4.53 ± 1.16, and 2.14 ± 0.92 mm on the X-, Y-, and Z-axes, respectively. There was no significant difference in respiratory liver motion between group C (displacement: 3.23 ± 1.47, 9.95 ± 2.32, and 2.92 ± 1.10 mm on the X-, Y-, and Z-axes, respectively) and group D (displacement: 3.35 ± 1.55, 9.53 ± 2.62, and 3.35 ± 1.73 mm on the X-, Y-, and Z-axes, respectively). Abdominal compression was least effective in group C (compression on caudal umbilicus), with liver motion in this group similar to that of free-breathing patients (group D). CONCLUSIONS 4D-CT scans revealed significant liver motion control via abdominal compression of the subxiphoid area; however, this control of liver motion was not observed with compression of the caudal umbilicus. The authors, therefore, recommend compression of the subxiphoid area in patients undergoing external radiotherapy for intrahepatic carcinoma.

Abstract
Organophosphorus exposure affects different organs such as the lung, gastrointestinal tract, liver, and brain. The present experiment aimed to evaluate the effect of ginsenoside Rg3 on lung injury induced by acute omethoate poisoning. Rats were administered with omethoate subcutaneously at a single dose of 60 mg/kg, followed by ginsenoside Rg3 (5, 10, or 20 mg/kg) treatment. Histopathological examination of the lung was performed at 24 h after the omethoate exposure. The antioxidative parameters in the lung were also assayed. Moreover, the activities of acetylcholinesterase, myeloperoxidase, and the content of tumor necrosis factor α (TNF-α) in the lung were determined. The results showed that ginsenoside Rg3 attenuated omethoate-induced lung injury. Ginsenoside Rg3 increased the level of glutathione in the lung ( p < 0.05 or p < 0.01). The altered activities of superoxide dismutase and catalase in the lung were also ameliorated by ginsenoside Rg3 treatment ( p < 0.05 or p < 0.01). Ginsenoside Rg3 caused significant reductions in the contents of malondialdehyde, TNF-α, and the activity of myeloperoxidase ( p < 0.05 or p < 0.01). The present study demonstrated that ginsenoside Rg3 had a protective effect against omethoate-induced lung injury in rats, and the mechanisms were related to its antioxidant potential and anti-inflammatory effect.

Abstract
A high preoperative peripheral blood neutrophil-to-lymphocyte ratio (NLR) has been reported to be a predictor of poor survival in patients with various cancers. The aim of this study was to evaluate the predictive significance of the NLR in patients undergoing hepatectomy for intrahepatic cholangiocarcinoma (ICC). From 2005 to 2011, 322 patients who underwent hepatectomy for ICC were enrolled in this retrospective study. Clinicopathological parameters, including NLR, were evaluated to identify predictors of overall and recurrence-free survival after hepatectomy. The best cutoff for NLR was 2.49, and 177 of 322 patients (54.9 %) had an NLR ≥ 2.49. The 5-year survival rate after hepatectomy was 51.1 % in patients with NLR < 2.49 and 24.8 % in those with NLR ≥ 2.49 (P = 0.0001). Univariate analyses revealed that NLR was significantly associated with recurrence-free survival (RFS) and overall survival (OS; both P < 0.05). Multivariable analyses revealed that elevated NLR independently predicted poorer OS (P = 0.003, hazard ratio [HR] = 1.600). In summary, our results indicate that elevated NLR is a promising independent predictor of poor survival after hepatectomy in patients with ICC.

AIM: To investigate the clinical features and prognoses of elderly patients with esophageal carcinoma and to compare the effects of radiotherapy and rates of treatment-related pneumonitis (TRP) between elderly and non-elderly patients.
METHODS: A total of 236 patients with esophageal carcinoma who received radiotherapy between 2002 and 2012 were enrolled. The patients were divided into two groups: an elderly group (age ≥ 65 years) and a non-elderly group (age < 65 years). The tumor position and stage, lymph node and distant metastases, and incidence and severity of TRP were compared. Multivariate analysis was applied to identify independent prognostic factors.
RESULTS: The median overall survival times after radiotherapy in the elderly and non-elderly groups were 18.5 and 20.5 mo, respectively. Cox regression analysis showed that TRP grade and tumor-node-metastasis (TNM) stage were independent prognostic factors in the elderly group. High-dose radiotherapy (> 60 Gy) was associated with a high incidence of TRP. Tumor TNM staging was significantly different between the two groups in which TRP occurred. Multivariate analysis showed that TNM stage was an independent prognostic factor. Esophageal carcinoma in elderly patients was relatively less malignant compared with that in non-elderly patients.
CONCLUSION: An appropriate dose should be used to decrease the incidence of TRP in radiotherapy, and intensity modulated radiation therapy should be selected if possible.

Abstract
Microsurgical procedures for coverage of foot and ankle defects now are undertaken with a better understanding of biomechanical requirements, and concern for durability, aesthetics, donor site morbidity, and shoe fit. Well-contoured muscle flaps including the latissimus dorsi, rectus abdominis, and gracilis muscles frequently are used along with thin cutaneous flaps, especially from the lateral arm. When good local options are absent and exposed nerves, tendons, and bone, and surgical hardware are present, acute free flaps and delayed primary procedures are done frequently with excellent success rates (> 90%). Surgical adjuncts and pedorthic devices are used readily to enhance functional outcomes and to resolve shoe fitting and tissue breakdown problems. Free tissue transfers for foot and ankle coverage defects have reached state-of-the-art status, having been refined significantly to resolve many earlier problems.

Abstract
18 cases of myopic anisometropia were treated by radial keratotomy (RK). The preoperative myopia in eyes with higher degrees of refractive error ranged from -3.25 to -11.00D (mean = -6.53D), the anisometropia ranged from -2.50 to -11.00D (mean = 4.95D) and the visual acuities of the naked eyes were 0.02 to 0.15 (mean = 0.08). A half year after the operation, on the average, there was a 0.46 increase in visual acuity, -4.57 D decrease in myopia and -3.60D decrease in anisometropia. Postoperatively, 14 cases had regained the binocular single vision and 6 cases had 60" stereoscopic vision which is in the normal range. Therefore, it is considered that RK operation not only can decrease myopic degree and increase visual acuity, but also can decrease or even eliminate anisometropia to facilitate the recovery of binocular single vision. In monocular or anisometropic myopia, if the corrected visual acuity of the myopic eye or the eye with higher degree of myopia in a case is not below 0.6, RK operation is indicated and if the anisometropia is lower than -9.00D, postoperatively, binocular single vision may be recovered. The preoperative examination of myopic anisometropia, the method of predicting prognosis and some attention points in the treatment are also mentioned in the paper.

Abstract
This paper describes the successful reconstruction of badly injured thumbs in nineteen patients with transposition of a neurovascular pedicle island flap from the dorsum of the index finger. The flap has a consistent arterial supply (the first metacarpal artery), good sized veins, and terminal branches of the superficial radial nerve. Five patients had either palmar, dorsal, or circumferential loss of soft tissue from the thumb. Twelve patients had acute traumatic amputations requiring distal thumb reconstruction, and two patients had distal amputations with late reconstruction. In both immediate and late reconstruction, we maintained length and skin coverage with good circulation and sensation. This one-stage operation requires less postoperative care than many other procedures currently in use and may be employed in a wider variety of cases.

Abstract
Press-fit titanium grommets were developed to shield flexible hinged silicone implants used for arthroplasty of the radiocarpal, metacarpophalangeal, and metatarsophalangeal joints. Since 1985, 179 titanium circumferential grommets were used in 90 first metatarsophalangeal joints with excellent, pain-free, functional results and favorable bone response around the implant stems and at the bone-grommet interface. There were no complications due to particulate reactivity, implant fracture, or grommet fracture. The use of circumferential titanium grommets appears to be a safe and effective method to improve the long-term durability of flexible hinge implant arthroplasty of the first metatarsophalangeal joint.

Abstract
The authors report a case of successful replantation of all fingers in a ten-finger complete amputation. Among the factors responsible for the successful outcome were an adequate number of microsurgically-trained resident surgeons and staff, good organization and supervision by senior staff, emphasis on precision and perseverance in the operative procedures, and postoperative management. Follow-up is 15 months, and the patient now has a pair of functionally and cosmetically good hands.
