Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by the degeneration of upper and lower motor neurons selectively. Although the motor system lesion is the most predominant clinical manifestation of ALS, with the progression of the understanding of the pathogenesis and clinical detection of the disease, more and more patients are found to have extra-motor features of ALS, such as somatosensory involvement, etc. The research results demonstrated that ALS might be a kind of disorder combined with sensory disturbance according to the electrophysiology, neuropathology, neuroimaging, animal model simulation, genetic evidence, and other methods detected. We, herein, review the prevalence and detection methods especially the aspect of genetic associations implicated in the sensory nerve disturbance of ALS.

Objective To investigate the levels of the mRNA expression of TIM-3 and Galectin-9 in peripheral blood mono-cytes (PBMCs)of acute exacerbation asthma patients and their clinical significances.Methods 60 patients with acute exac-erbation asthma (eliminating 15 cases of non-conform to the regulations)and 30 cases of healthy subjects were collected from January to October of 2014.Used fluorescence quantitative real-time reverse transcription-polymerase chain reaction to measure the mRNA expression of TIM-3 and Galectin-9 in PBMCs of patients with asthma and healthy controls.Results The expression of TIM-3,Galectin-9 and IFN-γmRNA in the PBMCs from acute exacerbation asthma patients were all ab-normally higher than healthy controls (U =458.5,P =0.019;U =437.5,P =0.010;U =260,P <0.001).There were statis-tically significant differences between them.Conclusion TIM-3/Galectin-9 pathway may participate in the occurrence,devel-opment of asthma.TIM-3 or (and)Galectin-9 may prove to be an important target for treatments to asthma.

AIM:To investigate the effects of glucagon-like peptide-1 (GLP-1) on mRNA expression of SOCS-3 and SREBP-1c in the rats with nonalcoholic fatty liver disease.METHODS:Male SD rats were randomly divided into normal control ( NC) group, high fat ( HF) group and HF+liraglutide ( Lira) group.The rats in HF group and HF+Lira group were given high-fat diet for 16 weeks.After 12 weeks of high-fat diet feeding in HF+Lira group, Lira (600μg? kg-1? d-1 ) was intraperitoneally injected for 4 weeks.At the end of the 16th week, the rats were killed.The pathologi-cal changes of the liver were observed under optical microscope.The serum levels of alanine aminotransferase ( ALT) , as-partate aminotransferase ( AST) , triglyceride ( TG) and total cholesterol ( TC) were detected by automatic biochemical an-alyzer.TG contents of liver were measured by GPO-PAP method.The fasting insulin ( FINS) was determined by ELISA, and insulin resistance index was assessed by homeostasis mode assessment ( HOMA-IR) .The mRNA expression of SOCS-3 and SREBP-1c in the liver tissues was detected by RT-qPCR.RESULTS:Compared with NC group, HOMA-IR, TG of liver, and the serum levels of ALT, AST, TG, TC and FINS in HF group were obviously increased (P<0.01).Compared with HF group, HOMA-IR, TG of liver, and the serum levels of ALT, AST, TG, TC and FINS in HF+Lira group were all obviously decreased (P<0.05 or P<0.01).The mRNA expression of SOCS-3 and SREBP-1c in HF group was signifi-cantly higher than that in NC group (P<0.01).The mRNA expression of SOCSV3 and SREBP-1c in HF+Lira group was significantly decreased as compared with HF group (P<0.05).CONCLUSION:Liraglutide may improve the IR and re-
duce TG of liver through decreasing the mRNA expression of SOCS-3 and SREBP-1c, so as to play a therapeutic role in nonalcoholic fatty liver disease.

AIM To determine the contents of polymethoxylated flavones in Citri Reticulatae Pericarpium from eleven cultivar origins.METHODS HPLC was applied to screening extraction solvents (methanol,anhydrous ethanol,95％ ethanol,ethyl acetate and petroleum ether).Ultraviolet-visible spectrophotometry was adopted in the content determination of polymethoxylated flavones in eighteen batches of samples,nobiletin was taken as a reference substance,and the detection wavelength was set at 330 nm.RESULTS Ethyl acetate exhibited the best extraction effect,so it was selected as extraction solvent.Nobiletin showed a good linear relationship within the range of 3.024-13.104 μg/mL (R2 =0.999 8),whose average recovery was 101.37％ with the RSD of 1.34％.The contents of polymethoxylated flavones had obvious differences among samples from different cultivar origins,which were relatively high from Citrus reticulata ‘ Chachi’,Citrus reticulata ‘ Dahongpao’,Citrus reticulata ‘ Tangerina’,Citrus reticulata ‘ Ponkan’,Citrus reticulata ‘ Kinokuni’and Citrus reticulata ‘ Shiyueju’(more than 0.4％).CONCLUSION This simple and accurate method can effectively eliminate the interference of another flavonoids,which is suitable for the content determination of polymethoxylated flavones in Citri Reticulatae Pericarpium.

Objective To analyze the clinical profile and short-term postoperative prognosis of mixed hepatocellular carcinoma and cholangiocarcinoma (mHCC-CC). Methods Clinical data of 17 mHCC-CC cases undergoing hepatectomy were retrospectively analyzed. Results Patients average age was 53 years (27～76 years).There were 11 males (64.7％) and 6 females.Ten patients (58.8％) were asymptomatic,twelve patients(70.6％ ) had positive serology for hepatitis B infection,serum AFP levels ＞25 ng/ml in 12 cases. Serum CA199 levels ≥ 37 U/ml in 4 cases. All patients underwent radical hepatectomy,including ＞ 1.5 cm safe margin and lymphadenectomy.The 6-,12-,and 18-months overall survival rate was 93.8％,86.5％ and 57.7％,respectively.The 100- and 200-day disease-free survival was 65.3％ and 43.5％.The median disease-free survival was 161 days. Conclusions mHCC-CC is difficult to diagnose preoperatively.The diagnosis depends on pathological examination.The main treatment was surgical resection.The prognosis of mixed primary liver cancer is poor and tends to recur early after hepatectomy.

Objective To observe the effect of modified SanJia-Fumai decoction with hormone replacement therapy on the endocrine and immune function of patients with climacteric syndrome. Methods A total of 84 patients with climacteric syndrome were divided into two groups according to the random number table, 42 cases in each group. The control group was treated with hormone replacement therapy. While the observation group was treated with modified Sanjia-Fumai decoction on the basis of the control grop. Both groups were treated for 4 weeks. The efficacy by scoring the changes of the patients clinical symptoms and signs was evaluated, and the serum hormones (LH, FSH, E2) levels were detected by radioimmunoassay, and the immune function index (CD3+, CD4+, CD8+) levels by immunofluorescence method, and the IL-2 by ELLSA. Results After treatment, the total efficiency of observation group was 92.8％ (39/42), while the control group was 73.8％ (31/42), and the difference was statistically significant (Z=-2.736, P=0.003). After treatment, the scores of hot flashes, menstrual disorders, insomnia and dreaminess, hot sweating, restlessness and dry mouth constipation in the observation group were significantly lower than those in the control group (t were 7.745, 10.364, 11.201, 16.765, 18.442, 18.625 respectively, P<0.001); the Serum LH and FSH levels in observation group were significantly lower than those in control group (t were 4.837, 5.016 respectively, P<0.01); the E2 level was significantly higher than that of control group (t=7.309, P<0.01). The levels of CD3+, CD4+, CD4+/CD8+, IL-2 in the observation group were significantly higher than those in the control group (t were 5.139, 6.083, 6.158, 5.932 respectively, P<0.01); The level of CD8+ was significantly lower than that of the control group (t=5.994, P<0.01). Conclusions The modified SanJia-Fumai decoction with hormone replacement therapy can regulate the endocrine function, improve the body's immunity and improve clinical symptoms of climacteric syndrome patients.
