Objective To determine the correlation between aquaporin-4 antibody (AQP4-Ab) and optic neuropathy in patients with neuromyelitis optica spectrum disorder (NMOSD).Methods The clinical and biochemical data of 53 patients with NMOSD diagnosis based on AQP4-Ab level in Changhai Hospital between January 2010 and October 2015 were retrospectively analyzed.According to optic neuropathy occurrence,the NMOSD patients were divided into optic neuropathy and non-optic neuropathy groups.Clinical and biochemical characteristics were compared between the two groups.According to the serum AQP4-Ab levels,the NMOSD patients were divided into AQP4-Ab seropositive and seronegative groups.The incidence of optic neuropathy was compared between the two groups.The correlation between optic neuropathy and AQP4-Ab levels was analyzed.Results Between the optic neuropathy and non-optic neuropathy groups,no significant differences in sex,age at onset,disease course,serum alanine aminotransferase levels,protein levels in cerebral spinal fluid,IgG index,and oligoclonal band were observed (P > 0.05).However,statistically significant differences were found in frequency,superficial sensory impairment,serum creatinine level,and serum AQP4-Ab level (P < 0.05).Between the AQP4-Ab sempositive and semnegative groups,a statistically significant difference in the incidence of optic neuropathy was observed (F =4.93,P < 0.05).The incidence of optic neuropathy positively correlated with AQP4-Ab levels (r =0.297,P < 0.05).Conclusion NMOSD patients with AQP4-Ab seropositivity could be prone to optic neuropathy,and the correlation may be beneficial to early diagnosis,therapy,and monitoring of NMOSD.

Objectives To explore the correlation between the cerebrospinal fluid protein and facial paralysis in pa?tients with Guillain-Barre syndrome (GBS). Methods Clinical and biochemical data of 111 patients with GBS in depart?ment of neurology from January 2005 to September 2015 were retrospectively analyzed. According to facial paralysis, GBS patients were divided into the facial normal and paralysis groups. Their clinical and biochemical characteristics were compared between the two groups. According to level of cerebrospinal fluid protein, GBS patients were divided into cerebrospinal fluid protein normal, mild high and severe high groups. Incidences of facial paralysis were compared among these three groups. The correlation between the cerebrospinal fluid protein and facial paralysis was analyzed. Results There was no significant difference in gender, age, respiratory infection and other clinical symptoms (P>0.05), whereas there were statistically significant differences in cerebrospinal fluid protein, immunoglobulin G, and cerebrospinal fluid albumin/serum albumin ratio between the facial normal and paralysis groups (P<0.05). Among the three groups by differ?ent levels of cerebrospinal fluid protein, there were statistically significant differences in the incidence of facial paralysis (F=3.48,P=0.03). Cerebrospinal fluid protein was positively correlated with facial paralysis (r=0.288,P<0.01). Conclu? sions The incidence of facial paralysis is associated with the levels of cerebrospinal fluid protein. Thus, cerebrospinal flu?id protein may be helpful in monitoring of GBS patients with facial paralysis.

Non-invasive blood glucose monitoring will be the development direction for detecting the blood glucose concentration of body in time. In this way, the concentration of the blood glucose can be controlled effectively, then the complicating diseases of diabetes can be reduced, so it is of great significance for diagnosis and treatment of diabetes. The recent developments of non-invasive blood glucose concentration monitoring technologies, including basic principles, results of verification test and instruments, are discussed, especially three methods with instruments facing market. The existing problems of these methods are also discussed. Finally, some difficult points of current non-invasive blood glucose monitoring methods are further discussed and the future trend of the technologies has been pointed out according to the above analysis.

OBJECTIVETo assess the value of abdominal three-dimensional medical image visualization system (MI-3DVS) in assisting complicated hepatectomy.
METHODSTwenty-four patients undergoing complicated hepatectomy for hepatic carcinoma or hepatic focal nodular hyperplasia were enrolled in this study. Three-dimensional models of the organs, vessels and tumors were reconstructed with MI-3DVS, and virtual operations were carried out to assess the feasibility of hepatectomy. The diameter of the liver tumors, intraoperative blood loss and transfusion, complications, in-hospital mortality rate, and one-year survival rate were analyzed in these cases.
RESULTSThe operations were safely completed in all the cases without perioperative deaths. The mean diameter of liver tumor was 9.8∓4.3 cm, and the median volumes of intraoperative blood loss and transfusion were 800 ml and 600 ml, respectively, with a blood transfusion rate of 91.7% (22/24). The incidence of complications was 29.2% (7/24), and the one-year survival rate was 37.5%.
CONCLUSIONThree-dimensional techniques such as volumetric analysis and risk evaluation of residual liver blood supply and drainage can increase the accuracy of surgical planning and improve the safety of complicated hepatectomy.

Objective:To study and screen the differential expression of inflammatory proteins in diabetes skin ulcers and common skin ulcers, so as to provide experimental basis for further research on anti-inflammatory and healing drug targets of diabetes skin ulcers.Methods:The tissues of 11 patients with diabetes skin ulcer, 12 patients with common skin ulcer and 11 patients with normal skin were collected from the First Hospital of Hunan University of Chinese Medicine. The levels of inflammatory protein Toll like receptor 4 (TLR4), nuclear factor κB (NF-κB), pro-inflammatory factor interferon -γ (IFN -γ), tumor necrosis factor - α (TNF -α), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-1β (IL-1β), macrophage chemotactic protein-1 (MCP-1), anti-inflammatory factors epidermal growth factor (EGF), interleukin-4 (IL-4), and interleukin-10 (IL-10) were detected in three groups of tissues using enzyme-linked immunosorbent assay (ELISA).Results:Compared with normal tissues, the concentrations of TLR4, NF-κB, IFN -γ, TNF -α, IL-1β, IL-6, IL-8, MCP-1 and EGF in common ulcer skin tissues and diabetes ulcer tissues were higher, and the concentrations of IL-10 were lower, with statistically significant differences (all P<0.05); Compared with the normal tissue, the concentration of IL-4 in diabetes ulcer tissue was lower, the difference was statistically significant ( P<0.05); Compared with ordinary ulcer skin tissue, the concentrations of TLR4, NF-κB and MCP-1 in diabetes ulcer tissue were higher, and the concentrations of IL-4 were lower, with statistically significant differences (all P<0.05). Conclusions:The skin ulcer in diabetes patients will have inflammatory reaction, and high glucose promotes the inflammatory reaction of skin ulcer, which may be related to the abnormal expression of TLR4, NF-κB, MCP-1 and IL-4. TLR4/NF-κB signal pathway and inflammatory factors MCP-1 and IL-4 may be the target of the inflammation regulation of diabetes skin ulcer.
