Minimal hepatic encephalopathy (MHE)is defined as early hepatic encephalopathy without grossly evident neurologic abnormali-ties,but with cognitive deficits that can be revealed by psychometric testing.However,numerous studies have shown a lack of obvious clini-cal manifestations in MHE patients,and there is no international unified diagnostic gold standard for this disease.Affected patients′quality of life and ability to work are markedly impaired,and some even gradually progress to symptomatic hepatic encephalopathy.The treatment methods for MHE mainly include eliminating the precipitating factors for this disease and medication.This review presents the options for treatment of MHE and gives an objective evaluation of the efficacy of each treatment scheme.Currently,several treatment methods are used together,but no studies have demonstrated that combined use of treatment methods can improve the treatment outcome.

Objective To compare the clinical curative effect between transjugular intrahepatic portosystemic stent-shunt (TIPS) and TIPS together with gastric coronary vein embolization (GCVE) in treating cirrhosis portal hypertension (PHT) associated with upper gastrointestinal hemorrhage (UGH),and to discuss the necessity,feasibility and clinical curative effect of TIPS plus GCVE.Methods The clinical data of 38 PHT patients with UGH,who were admitted to authors' hospital during the period from April 2010 to May 2012,were retrospectively analyzed.Only TIPS was employed in 15 patients (group A),and TIPS plus GCVE was adopted in 23 patients (group B).Before and after operation,the indexes,hemodynamics of portal vein and spleen,the morphology of spleen,and the degree of gastrointestinal varices were determined and analyzed.The patients were followed up to observe the occurrence of postoperative complications.Results In both groups,the postoperative portal vein pressure showed an obvious reduction with accelerated velocity of flow,and the splenic venous congestion index was decreased,these changes were statistically significant when compared with the preoperative ones (P＜0.05),and which was more obvious in group B than in group A (P＜0.05).After the treatment,the esophagogastric varices (EGV) was obviously improved,the improvement rates of group B and group A were 94.7％ and 66.6％ respectively,the emergency hemostasis rates of group B and group A were 100％ and 75.0％ respectively,The rates of re-bleeding were 4.3％ and 28.5％ respectively;the above results of group B were statistically better than those of group A (P＜0.05).No statistically significant differences in liver function indexes existed between preoperative values and postoperative ones in the same group as well as in group comparison (P＞0.05).The differences in the postoperative hepatic encephalopathy (HE) occurrence and in primary patency rate of stent between the two groups were not statistically significant (P＞0.05).In both groups,the re-intervention patency rate was 100％.The incidence rate of HE in patients in whom the distal end of stent was located in the left branch of portal vein was strikingly lower than that in patients in whom the distal end of stent was located in the right branch of portal vein (P＜0.05).Conclusion For the treatment of PHT associated with UGH,TIPS combined with GCVE carries reliable curative effect,this therapy is superior to simple use of TIPS.

BACKGROUND: In the early stage following spinal cord injury, a series of changes in metabolism and secretion take place, such as accelerated bone resorption and decreased bone formation. Determination of the biochemical markers of bone metabolism early after spinal cord injury may help understand the metabolic changes and facilitate risk evaluation for osteoporosis on such occasion.OBJECTIVE: To study the earlychanges of bone mass and bone metabolism indices in guinea pigs with spinal cord injury and evaluate the impact of spinal cord injury on bone metabolism.DESIGN: Randomly controlled animal experiment. SETTING: Department of Rehabilitation Medicine, Zhongshan Hospital of Fudan UniversityMATERIALS: The experiment was conducted in the Institute of Rehabilitation Medicine, Zhongshan Hospital of Fudan University in March 2004. Twenty-three male guinea pigs with body weight of 427-710 g (averaging 570 g) were provided by the Experimental Animal Center,Zhongshan Hospital of Fudan University and divided into experimental group (n=10) and normal control group (n=13). All the guinea pigs were kept under the same environment and fed with standard food for two weeks.METHODS: Small microsurgery scissors was used to induce a 1.5-mm transverse incision of the spinal cord, with the bleeding carefully managed and the wound closed. Thirty minutes after surgery, the guinea pigs recovered consciousness with bilateral lower limb paralysis (hypertonic paraplegia) and loss of superficial and deep sensations, but without urinary and fecal incontinence. The animals in the control group had sham operation. After housing in the same environment with standard food for 2 weeks, urine,serum and shinbone samples were collected from the animals for measurement of serum bone alkaline phosphatase (BALP), urinary pyridinoline (Pyd)/creatinine (Cr) and Ca/Cr. t test and H test were used for comparison of the samples between the two groups.parison of biochemical markers for bone formation between the two groups.RESULTS: Ten animals were analyzed in each group. No significant difference was observed in the BMD and bone dry weight between the two groups (P ＞ 0.05), but the bone ash weight of experimental group was remarkably lower than that of the control group [(0.284±0.050) vs (0.361±0.064) mg, t=3.254, P ＜ 0.05). The experimental group had significantly lower serum BALP than the control group [(0.640±0.240)vs (1.328±0.606) U/L, H=9.499, P ＜ 0.05), but higher urinary Pyd/Cr [(0.206±0.080) vs (0.117±0.037), P ＜ 0.01) and Ca/Cr [(0.003±0.003)vs (0.002±0.002), P ＜ 0.05] than the control group (H=9.676, 4.124,P ＜ 0.05).CONCLUSION: After the spinal cord injury, bone resorption remarkably increases and the function of the osteoblasts is inhibited. Bone metabolic abnormalities can occur in the early stage of spinal cord injury, and the biochemical indices for bone metabolism are sensitive in evaluating the risks for osteoporosis after spinal cord injury.
