Objective To observe the effects of Shenfu injection on intestinal mucosal barrier of rats with hepatic ischemia-reperfusion.Method Ninety SD male rats and weight from 230 to 270g were randomly divided into three groups( 30 rats in each),and 30 rats in each group divided again into 6h and 12h group( 15 rats in each):(1)SO group received sham operation(SO);(2) IR + NS group received so and 0.9 normal saline intravenously imediately before the ischemia reperfusion injury;(3) IR + SF group received Shenfu injection intravenously imediately before the ischemia reperfusion injury,IR + NS group and IR + SF group occlusion of the hepatoduodenal ligament,and endotoxin,ALT and MDA were detected.Results The levels of ALT,MDA in IR + NS group were higher than those in IR + SF group,and the rate of bacterial translocation( BT)group.

Objective To study the clinical characteristics of bulbar myasthenia gravis (MG). Methods Retrospective review was performed on 166 patients with bulbar type of myasthenia gravis, diagnosed at Tongji Hospital in the period of May 1983 through October 2005.Results Bulbar MG was a relatively rare type of MG,accounting for 5.7% (166/2888) of MG classifications.Females were more often affected than males (the ratio of male:female was 1:1.35).The peak of onset age was at 20—40 years.The incidence of myasthenia crisis in the group was 26.5% (44/166).Myasthenic crisis occurred in 10.8% (18/166) of the bulbar MG patients within 6 months after onset,resulting in a mortality rate of 6.0% (10/166) in the group.Out of the group,30 cases experienced puhnonary infections (18.1%). Thirty cases were initially misdiagnosed as other diseases such as nasopharyngeal disorders (33/166, 19.9%).The routine therapy was not very satisfactory.Median dose cyclophosphamide therapy appeared to be effective for ameliorating refractory MG.Thymectomy was performed in 25 patients,with optimistic efficacy rate up to 80.0% (20/25) in a 3-year follow-up.Conclusions The clinical analysis in the current study suggested that the bulbar MG had its own characteristics in such aspects as progression of the disease, complications,treatment and prognosis.The information of the clinical manifestations presented in this study may be useful in diagnosing and treating bulbar MG.

ObjectiveTo investigate the relationship between the serum concentration of IL-6,S100β,NT-3 and the cognitive functions in first-episode schizophrenia characterized by positive or negative symptoms.Methods44 first-episode schizophrenic patients characterized by positive symptoms (positive group),36 first-episode schizophrenic patients characterized by negative symptoms (negative group) and 50 healthy controls (controls) were collected.The serum levels of IL-6,S100β and NT-3 were measured by enzyme-linked immunosorbent assay (ELISA).The systematic evaluation tool-MCCB was applied to assess cognitive function in patients and controls.ResultsNT-3 serum levels in positive or negative groups were lower than those in controls and the differences were significant((118.39±37.50) ng/L,(112.55±32.29) ng/L vs (141.18±29.67) ng/L) (P<0.01).IL-6 and S100β serum levels in positive or negative groups were higher than those in controls and the differences were statistically significant((5.74±1.00)ng/L,(5.07±1.17)ng/L vs (4.23±0.91)ng/L),((132.98±46.71)ng/L,(124.99±43.14)ng/L vs (103.63±31.57)ng/L)(P<0.01).IL-6 serum levels in the positive group ((5.07±1.17)ng/L) were lower than those in the negative group ((5.74±0.99)ng/L) and the difference was statistically significant (P<0.05).In MCCB test,the TMT scores in patients characterize by positive symptoms or patients characterize by negative symptoms were higher than those in healthy control group (P<0.01).BACS SC,HVLT-R WMS-Ⅲ,SS,NAB,BVMT-R,CF in patients characterize by positive symptoms or by negative symptoms were lower than those in healthy control group(P<0.01).There were no statistical difference in the MCCB scores between the patients with positive symptoms and negative symptoms.In positive group,there was a positive correlation between the IL-6 serum concentration and the general symptom scores in PANSS (P<0.05).In positive group,NT-3 serum concentration was positively correlated with the general symptom scores or total scores of PANSS (P<0.05).BVMT-R scores in MCCB were also positively correlated with IL-6 or NT-3 serum concentration in positive group (P<0.05).ConclusionThe impairment of part of cognitive functions for schizophrenic patients may be related to the serum protein factors.There may be different in pathophysiology between the first-episode schizophrenic patients characterized by positive symptoms and those characterized by negative symptoms.

OBJECTIVETo study the expression of gastrin(GAS) and gastrin releasing peptide(GRP) in patients with gastric cancer and investigate the clinical significance.

METHODSThe expression of GAS and GRP in sixty patients with gastric cancer was detected by using tissue chip technique and immunohistochemical methods.

RESULTSThe positive rates of GAS and GRP were 30.0% and 11.7% respectively in 60 cases with gastric cancer. The positive rates of GAS and GRP were higher in moderately and poorly differentiated cancers than those in well differentiated cancer (P< 0.05). The positive rates of GAS and GRP were significantly higher in mucinous adenocarcinoma and signet-ring cell carcinoma than those in other types of gastric cancer (P< 0.05). The positive expression of GAS and GRP in gastric cancer was correlated with lymph node metastasis (P< 0.05).

CONCLUSIONTissue chip technique is a feasible,rapid,economic and accurate approach for screening clinical tissue specimens on a large scale.

PURPOSE: The purpose of the present study was to investigate the aberrance of histone H3 lysine 4 trimethylation (H3K4me3) in patients with IgA Nephropathy (IgAN). MATERIALS AND METHODS: In this study, H3K4me3 variations in peripheral blood mononuclear cells (PBMCs) from 15 IgAN patients and 15 healthy subjects were analyzed using chromatin immunoprecipitation linked to microarrays analysis (ChIP-chip). ChIP real-time PCR was used to validate the microarray results. Expression analysis by quantitative real-time PCR (qRT-PCR) revealed correlations between mRNA and H3K4me3 levels. DNA methylation status was analyzed by quantitative methylation-specific PCR. RESULTS: We found that 321 probes displayed significant H3K4me3 differences in IgAN patients compared with healthy controls. Among these probes, 154 probes displayed increased H3K4me3 and 167 probes demonstrated decreased H3K4me3. For further validation, we selected 4 key relevant genes (FCRL4, GALK2, PTPRN2 and IL1RAPL1) to study. The results of ChIP real-time PCR coincided well with the microarray data. Quantitative RT-PCR revealed the correlations between the mRNA expression and the methylation levels of H3K4me3. Different degrees of DNA methylation alterations appeared on the selected positive genes. CONCLUSION: Our studies indicated that there were significant alterations in H3K4me3 in IgAN patients. These findings may help to explain the disturbed immunity and abnormal glycosylation involved in IgAN patients.

OBJECTIVE: To observe the effect of anti-osteoporosis drugs on the curative effect of femoral head replacement in the elderly patients with proximal humerus fracture. METHODS: From November 2012 to June 2016, 38 patients with proximal humeral fractures received humeral head replacement were divided into the treatment group and the control group according to whether the anti-osteoporosis drugs were used after the operation. The treatment group included 19 cases, of which 11 cases were three part fractures, 18 cases were four part fractures, and bone density was(0.58±0.14) g/cm²; the control group involved 19 cases, of which 10 cases were the three part fractures, 9 cases were four part fractures, and bone density was(0.58±0.11) g/cm². Periprosthetic bone mineral density(BMD) was measured at 4, 8, 12, 24 and 48 weeks after operation, and visual analogue scale(VAS) was used to evaluate the pain and Neer score was used to evaluate the function of the shoulder joint. RESULTS: The incisions of all patients were healed with grade A and no complications occurred. Thirty-five patients were followed up for 1 year. The bone density around the prosthesis of treatment group was higher than that of control group, the difference was statistically significant(<0.05);VAS in two groups had no statistical significance(>0.05). The total score and functional score of Neer in the treatment group were better than those in the control group, the difference was statistically significant(<0.05), and there was no significant difference in pain and activity score between the two groups(>0.05). According to the Neer score, the results of treatment group was excellent in 10 cases, good in 5 cases, fair in 3 cases;in the control group, 3 cases were excellent, 9 cases were good, and 5 cases were fair;the difference between the two groups was statistically significant(<0.05). CONCLUSIONS Artificial humeral head replacement combined with anti-osteoporosis drugs in the treatment of proximal humeral fractures in elderly patients can effectively improve the bone density around the prosthesis and restore shoulder function. The early clinical effect is satisfactory.
