Objective To report the clinical effects of microsurgery in treatment of infected extremities after blood vessel prosthesis were transplanted.Methods From Jan.1998 to Dec.2008,8 cases of major vascular injuries in extremities were blood-supplied by cross bridge vascular anastomosis from uninjured extremities,including 4 cases of femoral artery and vein,2 cases of popliteal artery and vein,and 2 cases of brachial artery and vein. Results After 3 years of follow-up,blood circulation of infected extremities were reestablished in each of 8 cases,as well as function and appearance recovered.Conclusion The procedure of cross bridge vascular anastomosis from uninjured extremities may efficiently restitute the blood supply of the infected extremities after blood vessel prosthesis were transplanted,and decrease the rate of amputation.

Objective:To determine the prevalence of sarcopenia and explore related influencing factors of sarcopenia in maintenance hemodialysis (MHD) patients.Methods:MHD patients aged ≥18 years old and receiving therapies of ≥3 months from March 2019 to December 2019 in Blood Purification Centre of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were retrospectively enrolled in this study. General data of the patients were collected. Grip strength was measured by the Jamar dynamometer and the chair stand was measured by a chair of standard height to assess skeletal muscle strength and appendicular skeletal muscle mass was measured by dual energy X-ray absorptiometry. Baseline data between MHD patients with and without myasthenia were compared. Logistic regression analysis method was used to analyze the influencing factors for sarcopenia in MHD patients.Results:A total of 125 MHD patients were enrolled, with 68 males (54.4%), age of (59.4±14.9) years and median dialysis age of 51.0(23.5, 101.0) months. Sarcopenia was diagnosed in 39 cases (31.2%). Compared with MHD patients without sarcopenia, age, tumor necrosis factor-α, von Willebrand factor (vWF) and proportion of using α ketones were higher, and serum carbondioxide combining power (CO 2CP), prealbumin, albumin and proportion of regular exercise were lower in MHD patients with sarcopenia (all P<0.05). Multivariable logistic regression analysis results showed that low CO 2CP ( OR=0.717, 95% CI 0.576-0.892, P=0.003), high vWF ( OR=1.037, 95% CI 1.016-1.058, P<0.001) and no regular exercise ( OR=0.309, 95% CI 0.118-0.810, P=0.017) were independent influencing factors of sarcopenia in MHD patients. Conclusions:The prevalence of sarcopenia in MHD patients is high. Low CO 2CP, high vWF and no regular exercise are independent influencing factors for sarcopenia in MHD patients.

Post-marketing evaluation is a process which evaluate the risks and benefits of drug clinical application comprehensively and systematically, scientific and systematic results of post-marketing evaluation not only can provide data support for clinical application of traditional Chinese medicine, but also can be a reliable basis for the supervision department to develop risk control measures. With the increasing demands for treatment and prevention of disease, traditional Chinese medicine has been widely used, and security issues are also exposed. How to find risk signal of traditional Chinese medicine in the early stages, carry out targeted evaluation work and control risk timely have become challenges in the development of traditional Chinese medicine industry.

This study was aimed to observe effect of pomegranate leaf tannin and ellagic acid on primary rat adipocyte differentiation and lipid metabolism-related factor expression. Primary rat preadipocyte was in vitro cultured to observe the effect of pomegranate leaf tannin and ellagic acid on lipid fat cells as well as mRNA expression of its related factor. The results showed that pomegranate leaf tannin and ellagic acid had obvious inhibition effect on fat formation in fat cells. It had certain inhibition effect on activities of lipoprotein lipase (LPL) and glucose-3-phosphate dehydrogenase (GPDH). It promoted fat decomposition and reduced intracellular lipid content. It upregulated PPARγ and fatty acid-binding protein (aP2). It downregulated obese (ob) gene level. It was concluded that pomegranate leaf tannin can inhibit fat generation of fat cells and promote fat metabolism. Ellagic acid was its main active ingredient, which had the same effect as pomegranate leaf tannin.

Traditional Chinese medicine Polygoni Multiflori Radix is dried roots of Polygonaceae Polygortum multiflorum Thunb. Its clinical application records were first discovered in literatures of the Tang dynasty. The origins, efficacy, toxicity, processing and taboos of Polygoni Multiflori Radix have been discussed in many ancient herb literatures. In recent years, with the increase in the public awareness in health, Polygoni Multiflori Radix admits preparations have been more widely applied in the treatment and prevention of diseases. However, there have been more and more reports about Polygoni Multiflori Radix induced liver injury, the safety of Polygoni Multiflori Radix has increasingly attracted attention of the society. In this paper, the authors summarized and analyzed the toxicity and medication risk factors of Polygoni Multiflori Radix recorded in ancient herb literatures, and proposed that more attention shall be given to the effect of the planting and processing methods on the components and toxicity of Polygoni Multiflori Radix in safety studies, which provides clues for the further studies.

BACKGROUND: Pancreatic damage in critically ill patients is associated with the progressive failure of multiple organs, but little is known about its clinical characteristics. At present, no guidelines are available for the diagnosis and management of pancreatic damage. This study was undertaken to analyze the clinical and pathologic characteristics of pancreatic necrosis in critically ill children, and to find some biological markers of pancreatic damage or pancreatic necrosis. METHODS: We retrospectively reviewed the clinical data, laboratory results, and autopsy findings of 25 children, who were admitted to Hunan Children's Hospital, China from 2003 to 2009, and died of multiple organ failure. The autopsy revealed pancreatic necrosis in 5 children, in whom sectional or gross autopsy was performed. RESULTS: The 5 children had acute onset and a fever. Two children had abdominal pain and 2 had abdominal bulging, flatulence and gastrointestinal bleeding. Four children had abnormal liver function, characterized by decreased albumin and 3 children had elevated level of C-reactive protein (CRP). B-ultrasonography revealed abnormal acoustic image of the pancreas in all children, and autopsy confirmed pancreatic necrosis, which may be associated with the damage of the adrenal gland, liver, lung, heart, spleen, kidney, intestine, thymus, mediastinal and mesenteric lymph nodes and other organs. Children 1 and 2 died of acute hemorrhagic necrotizing pancreatitis (AHNP);children 3-5 died of multiple organ dysfunction syndrome (MODS) due to pancreatic necrosis. CONCLUSION: Pancreatic damage or pancreatic necrosis in critically ill children is characterized by acute onset, severity, short course, multiple organ damage or failure. It may be asymptomatic in early stage, and easy to be ignored.

Objective To explore the correlation between MSCT perfusion parameters and biologic characters in nasopharyngeal carcinoma(NPC),and to investigate the clinical utility of MSCT perfusion for NPC.Methods Nasopharynx in 49 cases was studied using MSCT perfusion imaging,including 30 NPC cases before radiotherapy,14 post-radiotherapy NPC cases,and 5 cases of normal nasopharynx as controls. The perfusion data of tumors and nasopharyngeal wall such as blood flow(BF),peak enhancement index (PEI),time to peak (TTP),and blood volume (BV)were calculated.MVD defined by CD34 stain was counted in 16 cases of NPC.The correlation of MSCT perfusion parameters,MVD,and clinical stage was analyzed.Results 1 case of NPC failed in CT perfusion exam.In NPC group (n=29),BF,PEI,TTP, and BV were (48.6?16.9)ml?100 g~(-1)?min~(-1),(32.3?7.9)HU,(17.5?4.9)s,and (12.8? 4.4)ml?100 g~(-1),respectively.BF,PEI,TTP,and BV in control group (5 cases)were (15.9? 5.9)ml?100g~(-1)?min~(-1),(12.6?1.3)HU,(22.6?6.9)s,and (3.5?0.5)ml?100 g~(-1), respectively,and those in post-radiotherapy group (14 cases)were (25.2?7.0)ml?100 g~(-1)?min~(-1), (19.8 ?5.9)HU,(22.6?4.3 )s,and (6.1?2.4)ml?100 g~(-1),respectively.The perfusion values in NPC group had significant difference compared with those in the other two groups (P

ObjectiveTo investigate the effect of magnesium sulfate combined with monosialoganglioside on the recovery of motor function after spinal cord injury in rats.Methods48 healthy adult rats were randomly divided into groups A, B, C and D, and SCI was made by Allen's mode(10 g×25 mm) on spinal cord T9 extradually, 12 rats in each group. On the 1st d, 3rd d and 7th d after SCI, the recovery of motor function after spinal cord injury in rats was assessed with Basso-Beattie-Bresnahan(BBB)scale and slanting board test. Thiobarbituric acid was used to detect the concentration of malondialdehyde, and was observed the change of free radicals.ResultsAfter spinal cord injury in rats, BBB scores and slanting board test of groups A, B and C were better than group D. BBB scores and slanting board test of group C was better than groups A and B, which had significant difference on the 3rd d and 7th d after injury(P<0.05). After spinal cord injury in rats, concentration of malondialdehyde of groups A, B and C were lower than group D(P<0.05). Concentration of malondialdehyde of group C was lower than groups A and B, which had significant difference after injury(P<0.05).ConclusionMagnesium sulfate combined with GM1 can promote the recovery of motor function early after spinal cord injury in rats, and is superior to magnesium sulfate or GM1.
