Autoimmune encephalitis is a kind of inflammatory disease of central nervous system caused by abnormal immune response of body immune system to neuronal antigen,and is generally considered to be reversible encephalitis caused by noninfectious factors.Its characteristic manifestations include acute and subacute onset of cognitive dysfunction,epilepsy and mental disorder.With the discovery of related antibodies,summaries of clinical syndrome and application of new functional imaging instruments,the diagnosis of autoimmune encephalitis is increasingly standardized.The priority treatment of autoimmune encephalitis is immunomodulatory therapy,including glucocorticoid,immunoglobulin,plasma exchange and immunosuppressant.The other treatments could be the related tumor resection,electroshock therapy,etc.The symptoms in most patients can get substantial relief with active treatment.The present paper would focus on the research progress in treatment of autoimmune encephalitis.

Objective:To investigate the influence of unilateral periacetabular osteotomy (PAO) on the bony birth canal (BBC) in female patients with developmental dysplasia of the hip (DDH) by using pelvic 3D-CT maximum-inscribed-sphere (MIS) method.Methods:A total of 62 female DDH patients of childbearing age were included in the present study. The DICOM data of their pre- and post-operative pelvic CT was collected. The diameters of the MIS in 25 layers of the BBC were measured on the Medical Imaging Interaction Toolkit (MITK) platform. Lateral center edge angle (LCE), T?nnis angle and the distance between the medial margin of the femoral head and Kohler's line were measured on standing anteroposterior pelvic radiographs before and after unilateral PAO. Patients were divided into severe (LCE≤0°) and non-severe group (0°0.05). The anterior margin of acetabular fragment (1-13th layer) narrowed significantly (4.23-5.95 mm) after unilateral PAO with the narrowest part (5.62-5.95 mm) locating at the inferior margin of pubic ramus and the region superior to the lateral margin of obturator foramen (5-10th layer). The narrowest part of BBC before and after the surgery occurred at the level of bilateral sciatic spines (20th layer). The diameter of MIS changed significantly from 105.34±7.16 mm pre-operatively to 104.47±7.06 mm post-operatively ( t=2.198, P=0.032). There was a positive correlation between the inward displacement of the hip center and the narrowing of the 1-20th layer of the BBC. The decrease of T?nnis angle was positively correlated with the narrowing of the 1-10th layer of the BBC. The increase of LCE was negatively correlated with the narrowing of 2-5th layer of the BBC ( P<0.05). The standardized coefficients were with statistical significance when comparing the distance between the Kohler's line and the medial margin of the femoral head to the size of the 1-20th layer of the BBC ( β=0.27-0.50, P<0.05). The height was positively correlated with the size of the narrowest part of the BBC before and after the surgery ( r=0.565, r=0.586, P<0.001). There was no difference between severe group and non-severe group in their extent of BBC narrowing before and after surgery ( t=-0.685-0.655, P>0.05). Conclusion:Unilateral PAO results in mild narrowing of the BBC superior to the sciatic spine. The narrowest part of the BBC is located at the sciatic spine. Unilateral PAO has slight effects on the narrowest position of the BBC. Normal delivery of a healthy fetus in female patients with DDH of childbearing age could not be affected by unilateral PAO in normal BBC settings.

OBJECTIVETo investigate the feasibility of using percutaneous K-wires fixation after manipulative reduction combining with gypsum or splint fixation for treatment of the Barton fracture of aged people.

METHODSFrom June 2011 to May 2013, 91 patients with closed and fresh Barton fracture were analyzed retrospectively which information was complete. According to different methods these patients were divided into three groups: 33 patients in group A were treated by simplex fixation of gypsum or splint after manipulative reduction, including 20 males and 13 females with an average age of (63.27 ± 5.83) years old; 35 patients in group B were treated by percutaneous K-wires fixation after manipulative reduction combining with gypsum or splint fixation, including 23 males and 12 females with an average age of (64.25 ± 4.53) years old; 23 patients in group C were treated by open reduction and internal fixation including 15 males and 8 females with an average age of (64.04 ± 4.83) years old.

RESULTSAll the patients were followed up for 10 to 16 months with an average of 12 months by the method of recheckging in outpatient clinic. According Dienst scoring system: in group A, the result was excellent in 15 cases, good in 7 cases, fair in 11 cases; in group B, excellent in 25 cases, good in 6 cases, fair in 4 cases; in group C, excellent in 16 cases, good in 5 cases, fair in 2 cases. The excellent and good rate of group C was better than that of group B and A, further more group B is better than group A. According to X- ray standard, in group A, 26 patients were acceptable, 7 patients were unacceptable; in group B,28 patients were acceptable, 7 patients were uacceptable; in group C, 19 patients were acceptable,4 patients were unacceptable; there were no statistical significant difference (P > 0.05). There were 18 patients with emerging recrispation in group A, 10 patients in group B, 6 patients in group C, the result of group B and C was better than that of group A, and there was no statistically significant between group B and C (P > 0.05).

CONCLUSIONUsing percutaneous K-wires fixation after manipulative reduction combining with gypsum or splint fixation for treatment of the Barton fracture of aged people is an effective method, it has advantages of micro-invasived, reliable fixation, less complication, not need to fix wrist joint and early functional exercise.

Objective To analyze the sensitivity of auxiliary examinations in different periods of sporadic Creutzfeldt-Jakob disease (sCJD).Methods The clinical data of 53 sCJD patients were retrospectively analyzed including the different stages of skull diffusion-weighted magnetic resonance imaging (DWI),24-hour ambulatory electroencephalogram (EEG),18F-FDG PET/CT (PET-CT)and cerebrospinal fluid 14-3-3 protein.When calculating the sensitivity of an auxiliary examination,the diagnostic criteria were defined by combining the specific clinical manifestations with two or more positive results of other auxiliary examinations.Results There were 24,53 and 22 sCJD patients,respectively,met the criterion of early (E),middle (M) and later (L) stage of disease (some patients fit 2 or 3 stages).The sensitivity ofDWl (E:58.3％ M:85.4％,L:94.7％),EEG (E:45.8％,M:62.7％,L:77.8％),14-3-3 protein in cerebrospinal fluid (E:11.1％,M:52.9％) and PET-CT (E:80％,M:100％) increased gradually with disease progression,The sensitivity of PET-CT was higher than the other auxiliary examinations for E and M stages;no PET-CT was conducted in L stage.High signal regions mainly distributed in the cortex in E and M stages,but in L stage,no significant difference was found on the distribution of high signal regions between cortex and basal ganglia.Conclusions The sensitivities of the auxiliary examinations were different for sCJD patients in different stages.Reexaminations in different periods may improve the sensitivity for sCJD diagnosis.The sensitivity of PET-CT was high,and the combination of PET-CT and other auxiliary examinations may play a key role in the diagnosis of sCJD.

The mechanism of chromium accumulation and microstructure transformation of the fused yeast were studied in this paper.The result showed that the process of Cr6+ reduction and adsorption was accom-panied by the H+ consumption.The main adsorptive groups on the strain surface included amino,hydroxyl,phosphate group and amide,among which phosphate group played vital role in the chromium accumulation.The removal rate of chromium and reduction rate of hexavalent chromium declined 70% and 46%,respec-tively,when phosphate group was masked.During the adsorption process the chromium ions complexed on the surface of fused yeast was transported into the cell wall and combined with inclusion to form steady spe-cies and this took 90 min to reach the equilibrium.The biosorption and reduction of Cr on the cell surface would alter microstructure of cell surface,reduce cell membrane potential and increase cell membrane per-meability.

Objective To study the clinical characteristics of hepatitis B virus-related acute-on-chronic liver failure patients with familial aggregation.Methods 275 patients with hepatitis B virus - related acute-on-chronic liver failure were investigated.The patients were divided into familial aggregation and nonfamilial aggregation group basis on their epidemiological features.Clinical data and biochemical indicators between the two groups were analyzed statistically.Results 93 of 275 patients( 33.82％ ) case were family aggregation.There was no significant difference compared with chronic hepatitis B patients( 38.3％ ).The mean age of the two groups was 45.98 and 43.61 years old,respectively (P ＞ 0.05 ).The rates of liver cirrhosis in family aggregation group were significant higher than non - familial aggregation group( 73.91％ vs 58.24％,p ＜ 0.05 ).Serum total (TBil) and prothrombin activities ( PTA ) were no significant difference between the two groups,but ALT level in familial aggregation group was much higher (407.80U/L vs 256.45 U/L,P0.05 ).Conclusion Familial aggregation were not related to acute-on-chronic liver failure in chronic HBV hepatitis patients. But the rate of liver cirrhosis were higher in patients with familial aggregation.

We revisited the "Xiao Chaihu Decoction event (XCHDE)" occurred in late 1980s in Japan and the Bupleuri Radix related adverse drug reaction (ADR) reports in China After careful review, comparison, analysis and evaluation, we think the interstitial pneumonitis, drug induced Liver injury (DILI) and other severe adverse drug envents (ADEs) including death happened in Japan is probably results from multiple factors, including combinatory use of XCHDE with interferon, Kampo usage under modern medicine theory guidance, and use of XCHD on the basis of disease diagnosis instead of traditional Chinese syndrome complex differentiation. There are less ADE case reports related to XCHD preparation in China compared to Japan, mostly manifest with hypersensitivity responses of skin and perfuse perspiration. The symptoms of Radix Bupleuri injection related ADEs mainly manifest hypersensitivity-like response, 2 cases of intravenous infusion instead of intramuscular injection developed hypokalemia and renal failure. One case died from severe hypersensitivity shock. In Chinese literatures, there is no report of the interstitial pneumonitis and DILI associated with XCHDG in Japan. So far, there is no voluntary monitoring data and large sample clinical research data available. The author elaborated the classification of "reevaluation" and clarified "re-evaluation upon events" included the reaction to the suspected safety and efficacy events. Based on the current status of the clinical research on the Radix Bupleuri preparations, the author points out that post-marketing "re-evaluation upon suspected event" is not only a necessity of continuous evaluation of the safety, efficacy of drugs, it is also a necessity for providing objective clinical research data to share with the international and domestic drug administrations in the risk-benefit evaluation. It is also the unavoidable pathway to culture and push the excellent species and famous brands of TCM to the international market, in that it enhances the pharmaceutical manufactures the ability to control enterprise risk and eliminate the negative impact on traditional Chinese medicine. With the widely used and ADR report concentrated Radix Bupleuri injection as an example, the author provide a new approach to post-marketing clinical research.
