Obesity-related diabetes and the metabolic syndrome are significantly related to increased adipose tissue mass.Understanding of the effect of adipose tissue on the metabolic regulation will play a key role in therapeutic strategies aimed to reduce obesity-induced insulin resistance and alleviate symptoms of the metabolic syndrome.Visfatin is a novel adipokine that appears to be preferentially produced by visceral adipose tissue and has insulin-mimetic actions.We discusse the relationship between visfatin and metabolic syndrome as well as future therapeutic strategies to these diseases.

Bioelectrical impedance analysis(BIA)measures the body composition and its change by the electric feature of the extracellular fluid and intracellular fluid.It has been widely used for its noninvasiveness, convenience and accuracy, especially in population epidemiology and clinical monitoring.We aim to review the advantages and shortcomings,and try to discuss about the application of this technique and its potential.

Objective To study the clinical and pathological features in the elderly patients with chronic inflammatory demyelinating polyneuropathy (CIDP). Methods The features of the clinical manifestation, cerebrospinal fluid, electromyogram(EMG) and the biopsy results of sural nerve were presented and analyzed in 11 elderly patients with CIDP. Results Two cases had history of upper respiratory tract infection before the onset. As the initial symptoms , there were three cases with distal limb numbness, five cases with both distal lower extremities numbness, two cases with both distal upper extremities numbness and one case with difficulties to raise his head. Motor disorder was common to all the patients. There were eight patients with sensory dysfunction, three with limb muscle atrophy, one with muscle tenderness, eight with tendon reflexes weakened or disappeared, five with cranial nerve damaged, three with the autonomic nerve lesion, one with respiratory muscle involved, three with relapse. The score of the peak incidence as Modified Rankin was 3.02 points on average. Five cases had obvious albuminocytolgoic dissociation by the examination of cerebrospinal fluid, ten cases had neurogenic damage and one case had a combined myogenic and neurogenic damage by the EMG. The biopsy showed that six cases were with amyelination,six cases with inflammatory cell infiltrated, two cases with obvious remyelination, two cases with auxiliary fibers degeneration.And the methylprednisolone therapy was effective for eight cases. Conclusions The numbness of the distal limb is the initial symptom of the elderly patients with CIDP,most of whom are with sensory dysfunction ,and some with cranial nerves and autonomic nerve damage. The sural nerve biopsy has an important value for the diagnosis of the elderly with CIDP. The methylprednisolone therapy is proved to be effective for most patients.

Objective To study the effect of Rho-kinase inhibitor on experimental allergic neuritis. Methods 54 female Lewis rats were divided into three groups; EAN group, EAN + Rho-kinase inhibitor group, and CFA group. The rats were sacrificed on the 9th day, 17th day, and 26th day after immunized. The changes of weight, EAN incidence, and mean day of onset, mean maximum clinical score, and histopa-thology were observed. Results The clinical course in EAN group reached peak on the 17th day. Compared with EAN group, the weights of Rho - kinase inhibitor group were increased, while EAN incidence, mean day of onset delay, and the clinical scores in Rho-kinase inhibitor group were significantly decreased, ( P < 0.01) , and the demyelization and inflammation cells infiltrating was ameliorated in spinal nerve. CFA group didnt show any clinical manifestation. Conclusions Rho - kinase inhibitor may ameliorate the development of EAN through inhabiting the Rho/ROK signal pathway.

Objective To investigate the correlation factors of neonatal lenticulostriate vasculopathy. Method Four hundred and forty-seven newborns from Guangdong Women and Children Hospital were enrolled in this study. Clinical data of the newborns were obtained . Brain ultrasound studies of lenticulostriate artery were performed on the newborns. The logistic regression was performed for screening the correlation factors of neonatal lenticulostriate vasculopathy (P < 0.05). Results Results of the univariate logistic regression reveal the correlation factors tcontributing to LSV include congenital cytomegalovirus infection、neonatal asphyxia、congenital heart disease (CHD),hypertensive disorder in pregnancy (P < 0.05, respectively). Multivariate logistic regression analysis was performed on these factors. The congenital cytomegalovirus infection, neonatal asphyxia, CHD,hypertensive disorder in pregnancy were significantly associated with LSV (P < 0.05). Conclusion The congenital cytomegalovirus infection,neonatal asphyxia,CHD,hypertensive disorder in pregnancy are the correlation factors of neonatal lenticulostriate vasculopathy. LSV could be a predictive marker for the future development of neuropsychiatric disorders. The brain ultrasound studies of lenticulostriate artery is suggested to be performed on all infants with the correlation factors.

OBJECTIVETo investigate the therapeutical effects of KANGFUXINYE on the upper gastrointestinal injury induced by paraquat in rats, and to explore the proper mechanism.

METHODSA total of 120 adult Wistar male rats were randomly divided into three groups, control group (CG), model group (MG) and treatment group (TG), 40 rats each group. The MG and TG were given 20% paraquat 50 mg/kg by oral administration, after 2 h the TG was given KANGFUXINYE solution 1.5 ml by oral administration, 3 times a day. The CG was given normal saline. On the 3rd, 6th, 9th, 12th and 15th days after exposure, 8 rats of each group were killed respectively, and the tissues from esophagus and stomach were collected and examined by HE staining for observing the mucosa injury. The superoxide dismutase (SOD) and malondialdehyde (MDA) of serum were detected.

RESULTSOn the 3rd, 6th, 9th, 12th and 15th days after exposure, the results of pathological examination showed that the mucosa injury in TG was significantly relieved as compared with MG, the activity of serum SOD reduced obviously and the MDA levels increased significantly in MG, as compared with CG (P<0.05). The activity of serum SOD increased obviously and the MDA levels decreased significantly in TG, as compared with MG (P<0.05).

CONCLUSIONThe results of present indicate that KANGFUXINYE has the therapeutical effects on the upper gastrointestinal injury caused by paraquat in rats. The mechanism of therapeutical effects may be due to the increasing SOD activity, eliminating free radicles and inhibiting the lipid peroxidation.

BACKGROUNDHelical tomotherapy (HT) is a new image-guided intensity-modulated radiation therapy (IMRT). The aim of this study was to evaluate the changes in the target volume and organs at risk (OARs) of patients with nasopharyngeal carcinoma (NPC) during helical tomotherapy.

METHODSForty-three patients with NPC and treated via HT from March 2008 to January 2010 were reviewed retrospectively. Repeated CT scanning and plan adaptation were conducted at the 20th fraction during radiotherapy. The volumetric differences between the two scans were evaluated for nasopharyngeal tumor and retro-pharyngeal lymph nodes (GTVnx), neck lymph nodes (GTVnd), and parotid glands, as well as the axial diameter of the head.

RESULTSThe median interval between the two scans was 25 days (23 - 28 days). The volumetric decrease in GTVnx was 30.1% (median, 29.8%) and in GTVnd 41.6% (median, 45.9%). The variation in the GTVnd volume was correlated with the weight loss of the patient. The volume of the left parotid gland decreased by 35.5% (median, 33.4%) and of the right parotid glands decreased by 36.8% (median, 33.5%). The axial diameter of the head decreased by 9.39% (median, 9.1%).

CONCLUSIONSThe target volume and OARs of patients with NPC varied considerably during HT. These changes may have potential dosimetric effects on the target volume and/or OARs and influence the clinical outcome. Repeated CT scanning and replanning during the HT for NPC patients with a large target volume or an obvious weight loss are recommended.
