Objective To observe the therapeutic effect of electroacupuncture combined with rehabilitation exercises on swallowing function and cerebral perfusion in dysphagic stroke patients.Methods Sixty-two stroke pa- tients with dysphagia were randomly divided into a treatment group(n=32)and a control group(n=30).The treat- ment group received electroacupunture,rehabilitation exercise and conventional medical treatment,while the control group received only rehabilitation exercise and conventional medical treatment.They were treated once a day,6 times a week for 4 weeks.Water drinking test,stethocatharsis scores and swallowing fluorography were used to assess the swallowing function before and after treatment.Single photon emission computed tomography(SPECT)was also em- ployed to observe the status of cerebral perfusion before and after treatment.Results It was shown that the swallo- wing function and cerebral perfusion in the treatment group were significantly better than the control group after treat- ment.The effective rate in the treatment group was 96.88% while that of the control group was 66.67%.Conclu- sion Electroacupuncture combined with rehabilitation exercises is effective in treating the dysphagic stroke patients, and can significantly improve the brain perfusion of these patients.

OBJECTIVETo explore the risk factors of neural tube defects (NTDs) in Shanxi province where the incidence of NTDs had been the highest in China.

METHODS1:1 matched case-control study was used. All the objects collected from hospitals were investigated in standardized questionnaires about susceptible risk factors for NTDs and were genotyped for methylenetetrahydrofolate reductase (MTHFR) C667T polymorphism by PCR-RFLP method. The risk factors of NTDs were analyzed by conditional logistic regression and by SPSS 11.5 statistical software. We also analyzed the univariable and multi-variables in order to independently investigate the MTHFR genotype and maternal periconceptional adverse factors influencing on NTDs.

RESULTSComparing MTHFR gene frequency between case group and control group, our results showed that three genotypes were found in MTHFR C677T. There was significant difference between two groups at 0.01 level (chi2 = 14.61, P = 0.001) about the three genotypes. The MTHFR T allele frequency of mother with NTDs (60.6%) was higher than that of the control (41.4%), and there was significant difference between them (chi2 = 14.59, P < 0.001). By univariate conditional logistic regression analysis, it was indicated that 15 factors were correlated with NTDs (P < 0.05) in the level alpha = 0.05. By multi-variables conditional logistic regression analysis, four factors were connected to NTDs: frequency of pregnancy (OR = 2.87, 95%CI: 1.28 - 6.44), contacting chemical combination in early pregnancy (OR = 16.18, 95%CI: 1.18 - 221.59), frequent taking of germinated potato (OR = 4.66, 95%CI: 1.78 - 12.17) and MTHFR C677T mutation (OR = 2.13, 95%CI: 1.08 - 4.21).

CONCLUSIONFactors as 'frequency of pregnancy', 'history of contacting chemicals', 'taking germinated potatoes in early pregnancy', as well as 'MTHFR C677T mutation' in mothers were important risk factors affecting the occurrence of NTDs in Shanxi province.

Abstract: Objective　To explore the spatial epidemiological characteristics of severe cases hand, foot and mouth disease (HFMD) in Guangxi, China, from 2014 to 2018, and to provide a basis for identifying the high-risk regions as well as the prevention and control of severe cases of HFMD in Guangxi. Methods　Spatial-temporal scanning analysis, global and local spatial autocorrelation analysis were used to analyze the spatial clustering of HFMD. The trend surface analysis was used to evaluate the spatial distribution trend of HFMD. Results　From 2014 to 2018, the incidence and severe case fatality rates of HFMD were 3.89/100 000 and 4.23%, respectively. Monte Carlo scanning analysis showed that the first cluster region was Cenxi City, the second cluster was mainly concentrated in northwest of Guangxi, and the aggregation time was mainly concentrated in April to May and August to October. The global spatial autocorrelation analysis showed that the severe HFMD was significant clustering distribution, and the Moran's I coefficients of the sever cases, severe morbidity and severe case fatality rate were 0.088, 0.118, 0.197, respectively (P<0.05). Local spatial autocorrelation analysis showed that hotspots of severe HFMD cases were concentrated in the southern Guangxi, mainly in Lingshan County. Anselin local Moran's I clustering and outlier analysis indicated that 5 high-high (H-H) clustering regions for fatality were Lingshan, Pubei, Zhongshan, Zhaoping and Pinggui County. There were 6 high-high (H-H) clustering regions for severe incidence rate, namely Lingshan, Qinnan, Lingyun, Youjiang, Bama Yao Autonomous and Pinggui County, and 1 high-low (H-L) clustering region, Cenxi County. The trend surface analysis showed that the overall number of severe cases of death decreased from east or west to the middle, and increased from north to middle, and then decreased to south. Conclusions　Severe HFMD cases in Guangxi have obvious spatial-temporal clustering, and the hop spots are mainly concentrated in southern Guangxi. The prevention and control of HFMD in areas with high incidence of severe cases should be strengthened to reduce the burden of HFMD cases.

OBJECTIVETo analyze the relationship between hepatitis B virus (HBV) precore (PC) and basal core promoter (BCP) mutations and HBV-related acute-on-chronic liver failure (HB-ACLF).

METHODSForty-four patients with HB-ACLF and 28 patients with chronic hepatitis B (CHB; used as controls) were enrolled and venous blood samples were collected from all individuals. The PC and BCP gene fragments were amplified by nested PCR. HBV genotype and BCP/PC mutations were determined by direct sequencing and analysis by BioEdit (version 7.0.9.0). Ten of the HB-ACLF patients were selected for follow-up (range: 2-8 weeks), which included once weekly sera collection to determine the relation of mutations and treatment response. Serum levels of HBV DNA were measured by real-time PCR assay, and alanine aminotransferase, total bilirubin, creatinine and albumin were measured by standard biochemical assay and used to determine the MELD score.

RESULTSAll 44 HB-ACLF patients were infected with HBV genotype C. In the CHB group, 26 patients were infected with genotype C and two with genotype B. Single mutations (A1762T, G1764A, T1753V, G1896A, and G1899A) and combined mutations (A1762T + G1764A, G1896A + G1899A, T1753V+ A1762T + G1764A, G1896A + G1899A + A1762T + G1764A, and A1762T + G1764A + G1896A) were more frequently detected in HB-ACLF patients than in CHB patients (P less than 0.05). A significantly higher proportion of PC/BCP wild-type sequences was found in patients with CHB than in patients with HB-ACLF (17.9% vs. 2.3%; x² = 5.440, P = 0.020). The proportion of patients carrying both PC and BCP mutations was significantly higher in HB-ACLF patients than in CHB patients (79.6% vs. 39.3%; x² = 12.021, P = 0.001). The proportion of patients carrying only BCP mutation was 42.9% in the CHB group and 20.5% in the HB-ACLF group (x² = 4.157, P = 0.041). No occurrences of only PC mutation were detected in either the CHB or HB-ACLF group. The combined mutations were present in all 10 of the HB-ACLF follow-up patients. Mutations G1899A, T1753V, and A1846T were correlated with disease recovery. Significant decreases in the MELD score were accompanied by decreases in the A1846T mutation.

CONCLUSIONSignificantly more HB-ACLF patients carried HBV with mutations in the PC and BCP than CHB patients. Moreover, more HB-ACLF patients carried HBV with PC + BCP combined mutations and PC mutation only. The G1899A, T1753C, and A1846T mutations were associated with HB-ACLF response to treatment and improvement in liver function.

Objective To explore the effects of lamotrigine on the cognitive function and the quality of life in epilepsy patients.Methods This was a prospective study and 91 newly diagnosed epilepsy patients were enrolled.The neuropsychological tests score and the quality of life in epilepsy inventory(QOLIE-31) were obtained before and after the treatment with lamotrigine.A battery of neuropsychological tests comprised the auditory verbal learning test(AVLT), the logical memory test(LMT), the digital symbol test(DST), the stroop color word test(SCWT), the trail making test(TMT), the verbal fluency test(VFT), the WAIS block design test(WBDT), the WAIS digital span test(WDST)and the Boston naming test(BNT). Results The repeated assessments in the patients taking lamotrigine were associated with significant improvements in many domains.The greatest changes were observed in the immediate and delayed recall of AVLT, DST, the time consuming of SCWT card C and TMT test A and B, the immediate and delayed recall of LMT, VFT, WBDT and BNT.For the quality of life, significant improvements were recorded in the fields of the seizure worry(38.81?16.06 vs 45.68?15.18), the overall quality of life(59.12?13.50 vs 64.99?13.33), the social function(64.59?25.14 vs 69.41?22.70)and the self-health evaluation (71.18?13.73 vs 76.75?11.30).Conclusion Improvements of the cognitive function and the quality of life can be observed in the initial period of medication with lamotrigine in epilepsy patients.

OBJECTIVETo study the expression of phosphatase and tensin homology deleted on chromosometen ten (PTEN) protein, a tumor suppressor gene in breast cancer and its correlation with p27(kip1) and cyclin D1 expression.

METHODSPTEN protein expression, p27(kip1) and cyclin D1 protein expression were detected by immunohistochemical method in paraffin sections from 61 women with primary breast cancer. PTEN protein expression was compared with clinico-pathologic parameters as related to p27(kip1) and cyclin D1.

RESULTSPTEN, being shown in the cytoplasm, was negative in 6.6% (4/61), reduced in 41.0% (25/61) and positive in 52.5% (32/61) samples. PTEN expression level was correlated with axillary lymph node status, loss of estrogen receptor stain, recurrence and metastasis. On univariate analysis, the disease-free survival rate of patients with higher PTEN expression (> 50% cells stained) was better than those with lower expression (P = 0.0101). However, there was no correlation between p27(kip1), cyclin D1 expression or PTEN expression.

CONCLUSIONPTEN, its lower expression being correlated with poor outcome of breast cancer patients, plays a prominent role in breast cancer. p27(kip1) or cyclin D1 may not be the primary downstream genes of PTEN in breast cancer.

OBJECTIVETo explore the effect of berberine on lipid metabolism disorder and lipid deposition in liver cells of non-alcoholic fatty liver disease (NAFLD) rats induced by high fat diet.

METHODSAfter one week adaptable feeding, 45 SPF level male SD rats were randomly divided into 3 groups, the normal control group, the model group, and the berberine group, 15 in each group. Except those in the normal control group, all rats were fed with high fat diet to prepare NAFLD model. As for rats in the berberine group, Berberine Hydrochloride was administered by gastrogavage. HE staining and oil red O staining were performed to identify the model after 8 weeks. Hepatocytes were isolated, and their activities and purities were tested by Typan blue staining and flow cytometry (FCM). Serum levels of TC, TG, HDL-C, and LDL-C were detected using automatic biochemical analyzer. mRNA expression levels of LXRα and FAS in liver cells were analyzed by Real-time quantitative polymerase chain reaction (PCR). Protein levels of LXRα and FAS in liver cells were examined by Western blot.

RESULTSThe NAFLD rat model was successfully established by high fat diet. The yields of purified liver cells in each rat were (6.0-7.5) x 10(8). The viability of isolated liver cells with purity over 90% (tested by FCM analysis) was higher than 95%. Compared with the normal control group,the expression of LXRα and FAS at mRNA and protein levels was higher in the model group (P < 0.01). Compared with the model group, the expression of LXRα and FAS at mRNA and protein levels was obviously down-regulated in the berberine group (P < 0.01).

CONCLUSIONSLXRα/FAS signaling pathway was one of important signaling pathways of NAFLD lipid metabolism disorders. Berberine could recover hepatocyte fatty deposits in NAFLD rats by adjusting the LXR/FAS signaling pathway of hepatocytes, which might be one of important mechanisms for fighting against NAFLD.

OBJECTIVETo explore the effects of soothing liver and invigorating spleen recipes on lipopolysaccharide(LPS) induced hepatocyte inflammation of rats and TLR4/p38MAPK signal pathway.

METHODThe hepatocytes of SD rats were cultured and identified in vitro. The medicated serum of soothing liver and invigorating spleen recipes was prepared. The hepatocytes were treated with soothing liver and invigorating spleen recipes. Then Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) expression in cultural supernatants were assayed by ELISA. The expressions of Toll-Like 4 (TLR4), p38 mitogen activated protein kinases (p38MAPK) and p-p38 mitogen-activated protein kinase (p-p38MAPK) were detected by Western blot.

RESULTThe rat medicated serum of soothing liver and invigorating spleen recipes was extracted for 2-3 mL. The purified rat hepatocytes were 1.5 x 10(8)-2.0 x 10(8). The cell viability was above 95% detected by Typan blue staining. The hepatocytes were identified by immumofluorescence assay. The detection of hepatocyte cultural supernatants: compared with that of the control group, IL-6 and TNF-α expression were increased in the LPS group (P < 0.01). While compared with that of the LPS group, the expressions of IL-6 and TNF-α were decreased after soothing liver and invigorating spleen recipes intervention (P < 0.01). The detection of hepatocyte proteins: compared with that of the control group, the protein expressions of p38MAPK, p-p38MAPK and TLR4 were all increased significantly in the LPS group (P < 0.01). Compared with that of the LPS group, the protein expressions of p38MAPK was decreased significantly in SB239063 group and it was also decreased in the soothing liver and invigorating spleen recipes group, but with no significant difference. Compared with that of the LPS group, p38MAPK expression was reduced significantly in the soothing liver and invigorating spleen recipes group and the SB239063 (p38MAPK pathway inhibitor) group (P < 0.01). TLR4 protein expression was decreased markedly in the soothing liver and invigorating spleen recipes group (P < 0.01) but had no difference between the SB239063 group and the LPS group.

CONCLUSIONThe soothing liver and invigorating spleen recipes may regulate hepatocyte inflammatory injury of rats through TLR4/p38MAPK signaling pathway.
