Objective To investigate the types of ultrasonographic appearance of post-hepatectomy in operative position. Methods The data about operative manner,operative position, type of plugger in residul cavitity of 176 cases who underwent hepatic operation,were collected. Their ultrasonographic findings of post-operative liver in operative position in different phrases after operation were analyzed retrospectively. Results The main appearance was: ① Absence of partial hepatic lobe or hepatic segment; ② anechoic area with thin wall or mixed mass in operative position; ③ conformation of irregular high-echo conglomeration in operative position, irregular wall thickeness and inhomogenous internal echoes appeared in anechoic area and mixed mass in operative position, color Doppler twinking artifact appeared around some plugger and residual cavity which made by curettage and aspiration technique with time passing by. Conclusions Ultrasonographic appearance of post-hepatectomy in operative position varies with different operative manner, operative position, resected area, and Absence or existence of plugger in residual cavity, different type of plugger in residual cavity.

Hypoglycemia is a common metabolic problem in newborn infants,which might lead to brain injury even brain death when it keeps extremely low for a long time.Therefore,it is of great importance to monitor blood glucose in neonates,especially in groups of infants who are at risk of hypoglycemia,in order to identify and treat this condition and prevent adverse neurological outcomes promptly.It is given that infant of a diabetic mother,preterm neonate,low birth weight and asphyxia are its risk factors.Relative to blood glucose monitoring methods in clinical,continuous glucose monitoring system is comprehensive,continuous and with low pain.Continuous glucose monitoring system has been applied in high-risk neonates of hypoglycemia in recent years.It is of great help to understand the complete picture and change trend of blood glucose,optimize blood glucose management,study newborn glucose metabolic characteristics and the relationship between hypoglycemia and brain damage,so as to define and manage neonatal hypoglycemia.

BACKGROUND:To optimize the oral implant design in the abutment angle has an important effect on bone resorption, and meanwhile, the high bite force from patients is also crucial to rebuild bone absorption.
OBJECTIVE:To optimize the model design of the maxilary anterior teeth using Ansys Workbench 13.0 software and to investigate the stress size on the cortical and cancelous bone from different angled abutments and different loads of the central incisor.
METHODS:A three-dimensional finite element model of the V-shaped cylindrical threaded implants in the maxilary bone. Abutment angle was set as 0°, 5°, 10°, 15°, 20°, 25°, 30°, and the load stress was set as 90, 105, 120, 135, 150, 165, 180, 195, 210 N. Occlusion of the central incisor was simulated on the implants, and then, buccolingual mechanical loads were loaded on the center of prostheses to observe the effects of different abutment angles and loads on the Von Mises peak stress of the maxila and mandible.
RESULTS AND CONCLUSION:Under the influence of a single factor, when the abutment angles acted as variables, the Von Mises peak stress of the cortical and cancelous bone was respectively increased by 60.60% and 69.30% under labial or palatal loads; when the loading stress acted as variables, the Von Mises peak stress of the cortical and cancelous bone was increased by 68.74% and 69.30% under buccolingual loads. When the loading stress was less than 150 N and the abutment angle was less than 25°, the slop of tangent for the mandible Von Mises stress response curve was-1 to 0. It seems from the mechanical analysis that the stress of cancelous bone is more susceptible to abutment angle and load stress; the optimal abutment of screwed implant should be designed to an angle less than 25° and an bite force less than 150 N.

[Summary] 2015 AACE/ACE Clinical Practice Guidelines for Integrated Management of Diabetes are updated and revised on the basis of 2011 edition. The guidelines highlight the comprehensive consideration of micro- and macro-vascular risks rather than merely focusing on the strategies and approaches of glycemic control. The guidelines also emphasize individualized targets for weight loss and the management of hyperglycemia ,dyslipidemia and hypertension and that more attention should be paid to safety of individualized treatment other than efficacy.

Objective:To evaluate the impact and predictive value of neutrophil-to-lymphocyte ratio( NLR) ,derived neutrophil-to-lymphocyte ratio( d-NLR) ,platelet-to-lymphocyte ratio( PLR) and lymphocyte-to-monocyte ratio( LMR) on the prognosis of patients with colorectal cancer with curative resection.Methods: Retrospective analysis of 205 cases of clinical data and returning data after patients with colorectal cancer surgery,ROC curve was applied to determine thresholds for four biomarkers and their prognostic values were assessed using Kaplan-Meier curve,univariate and multivariate COX regression models of patients with NLR,D-NLR,PLR and LMR and other clinicopathological factors and the relationship between the 5-year recurrent-free survival( RFS).Results:According to the ROC curve,LMR could not be used as a potential diagnostic biomarker for subsequently analysis,for its AUC was less than 0.50, The optimal cut-off values were 3.12 with the highest specificity and sensitivity ( 75% and 73.1%) for NLR, while in the univariate analysis show,NLR,D-NLR and PLR were all risk factors of poor recurrence-free survival ( P<0.05 ) , the multivariate regression analysis,NLR≥3.12 and colorectal cancer staging were independent risk factors of prognosis of colorectal cancer.Conclusion:NLR≥3.12 can provide improved accuracy for predicting clinical outcomes in surgical CRC patients under surgery resection.

Objective To study the effect of expansion ex vivo on the hematopoietic reconstitution of umbilical cord blood (UCB) hematopoietic cells, and to find a probable way of UCB transplantation (UCBT) to be used on adults. Method Three groups of UCB hematopoietic cells were transplanted to lethally irradiated BALB/C mice: fresh cells, a half part of fresh cells and a half part of cells expanded for a week, cells expanded for a week. Results All the three groups of cells could reconstitute hematopoiesis. The cells in the latter two groups could more rapidly accelerate the recovery of early-period hematopoiesis. The death rate of the mice in second group was the lowest among three groups. Conclusion The way transplanted with a half part of fresh UCB hematopoietic cells and a half part of UCB hematopoietic cells ex vivo expanded for a week may be a probable one for adult UBCT.

[Objective]To evaluate the efficacy of nerve transfer for reconstructing the sensory function of the sole.[Method](1)Select saphenous nerve as donor nerve for the patients with the sensory loss beneath ankle level:dissect and cut off the saphenous nerve at the medialposterior aspect at upper-middle 1/3 of the leg and divide the gastrocnemius to expose the tibial nerve at the medialposterior aspect of the tibia, cut off partly nerve fibre of the tibial nerve and then end-to-end anastomose to the proximal end of the saphenous nerve. (2) Select sural nerve as donor nerve for the patients with sensory loss of sole only:dissect and cut off the sural nerve at the posterior aspect of the lateral malleolus, expose the tibial nerve at the posterior aspect of the medial malleolus and then cut off partly nerve fibre of the tibial nerve. The sural nerve was comdicted from the subcutaneous tunel at the anterior aspect of the Achilles's tendon to the posterior aspect of the medial malleolus and end-to-end anastomose to the partial nerve fibre of the tibial nerve. [Result]All the 9 cases were followed up from 1.5 to 2 years(mean 2 l months). The SCV(sensory conduction velocity) of the tibial nerve was ranged from 36.1 to 41.2 m/s, mean 38.3 m/s and the amplitude of wave (peak-to-peak amplitude) was a range from 7 to 15.3?V, mean 11.2 ?V by orthodromic electrophysiologic techniques. All 9 cases regained the sense of pain and touch of the sole.Three cases restored their sense of two point discrimination. All the patients expressed their satisfaction with their ability of walk and no muscles atrophy of the foot. The sensory loss in donor region was oberserved only lateral part of the foot beneath the lateral malleolus (sural nerve as donor nerve) and a small part of the anterior aspect of the ankle(saphenous nerve as donor nerve).[Conclusion]Nerve transfer can reconstruct the sensory function of the sole effectively.
