Cirrhosis with portal hypertension is a common disease which has a significant impact on the quality of patients' life. Esophagogastric devascularization (EGDV) has been demonstrated to be an effective method to treat portal hypertension, however certain complications are associated with it. The purpose of this study was to evaluate the effectiveness and clinical outcome of the selective EGDV (sEGDV) for the treatment of portal hypertension. The study was conducted prospectively from Jan. 1 2011 to Dec. 31, 2012, and 180 patients were randomized to the sEGDV group (n=90) or the non-sEGDV (n-sEGDV) group (n=90). Patients' demographics, preoperative lab test results and operative details were comparable between the two groups. Postoperative and short-term complications were analyzed in two groups. There was statistically significant difference (P<0.01) in the PVF reduction between the two groups. Post-operative complications showed no statistically significant difference between the two groups in the incidence of bleeding, ascites, acute portal vein thrombosis, fever and hepatic encephalopathy. Mortality between two groups was comparable. The incidence of splenic fossa effusion after the surgery was lower in sEGDV group than in n-sEGDV group. There were no significant differences in the short-term follow-up data such as esophageal varices and portal hypertensive gastropathy (P>0.05). It is suggested that sEGDV is a safe, simple and effective surgical procedure. It has both the advantages of the shunt and devascularization because it preserves body's voluntary diversion. With the advantage of low incidence of postoperative complications, it is an ideal surgical approach for the treatment of portal hypertension.

There are 250 species of Zanthoxylum (Rutaceae) in the world. This genus distributed in tropical and subtropical regions. Alkaloids are the major and representative ingredients in these plants including quinolines, isoquinolines, and amide alkaloids, with such biological activities as anti-tumor, anti-inflammatory, analgesic, anti-virus, anti-platelet aggregation, anti-bacteria and anti- oxidant. These species have been used for a long time to treat toothache, urinary and venereal diseases, lumbago and rheumatism. This review summarizes the chemical constituents and pharmacological activities from the Z. sppplants, in an effort to the systematic research and application of the alkaloids of this genus.

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 investigate the expression status of 11 different cancer/testis (CT) antigen genes in esophageal carcinoma.

METHODSEsophageal carcinoma tissue and adjacent normal esophageal mucosa taken from 35 esophageal carcinoma patients were assayed for the expression of 11 different CT antigen genes by RT-PCR techniques.

RESULTSOf the 11 CT antigen genes analyzed, none of them was expressed in normal esophageal mucosa. MAGE-3 was found to be the most frequently expressed in esophageal carcinoma tissues (62.9%), followed, in the order of expression frequency, by MAGE4 (31.4%), LAGE-1 (28.6%), MAGE-1 (25.7%), CT10 (20.0%), NY-ESO-1 (20.0%), CT7 (5.7%) and SCP1 (2.9%). No expression of SSX-1, SSX-2 and SSX-4 was found. Among the 35 cases, 28 (80.0%) expressed at least one CT antigen gene, 21 (60.0%) expressed more than 2 CT antigen genes, and 4 of the 21 (19.0%) expressed more than 4 CT antigens, which accounted for 11.4% of total number of patients (4/35). No CT antigen expression was found in the tumor tissue in 7 cases, including 5 cases in stage II and 1 case each in stage I and IV, respectively. Of the 11 CT genes examined, expression of 5 genes (NY-ESO-1, LAGE-1, MAGE-1, MAGE-3 and MAGE-4) was correlated with tumor progression. SCP-1 and CT10 expression was found more frequently in early stage patients. With progression of the disease, the frequency of co-expression of multiple CT antigen genes was significantly increased reaching 28.6% in stage III patients.

CONCLUSIONOf the 11 different CT antigen genes examined by RT-PCR in esophageal carcinoma, 8 genes were detected in various frequencies in 28 of the 35 esophageal cancer patients studied. They are candidate tumor-associated antigens in the preparation of tumor vaccines for immunotherapy in esophageal cancer patients.

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.

OBJECTIVETo analyze the full intronic sequences of human leukocyte antigen (HLA)-A alleles in Han Chinese.

METHODSThe full-length HLA-A alleles, including 8 exons and 7 introns, were amplified with a long-template PCR system from 165 donors from the Chinese Marrow Donor Program (CMDP). The products were cloned into a PGEM-T Vector System and sequenced from both directions. Genetic analysis was performed using a MEGA4.0 software. All sequences were aligned with a ClustalW algorithm. Phylogenetic trees were constructed with a neighbor-joining method. Genetic distances were estimated based on p-distance, and a bootstrap analysis was applied for assessing the confidence limits of the trees.

RESULTSA total of thirty-three full-length sequences of HLA-A alleles, containing 2902-2918 nucleotides, were derived. A total of 138 point mutations and 9 insertions or deletions were found among the 7 introns, which showed remarkable group specificity. Intron 1 appeared to be most polymorphic with the highest average GC content and evolutionary distances. Eight phylogenetic trees were constructed respectively with the derived full-length sequences as well as each of the 7 introns sequences. Based on full-length sequences, sequences of the HLA-A locus were classified into five groups: group I consisted of A*01/03/11/30; group II consisted of A*23/24(A9); group III consisted of A*02/68/69(A2/28); group IV consisted of A*26/34(A10); and group V consisted of A*29/31/32/33/74(A19). The five groups were derived from two ancient lineages, one including groups I and II, and another including groups III, IV and V. No substantial difference was detected between the trees constructed with the 7 intronic sequences, except that group II belonged to different lineages based on introns 2-5 and introns 1 and 7. The A*30 variant cluster was close to group I (A*01/03/11/30) and differed from group V (A19).

CONCLUSIONThe full-length sequences of 18 alleles have been submitted to GenBank and accepted by the international ImMunoGeneTics database (IMGT). Polymorphisms identified within the introns of HLA-A alleles showed remarkable group specificity. Such sequences seem to have substantially contributed to the recombination of the HLA-A alleles. The A*30 may represent an atypical group in which the rates of gene conversion and mutation have been unusually high.

Objective: To observe the improving effect of muscle regions of meridians needling method on the upper limb function in children with cerebral palsy of spastic hemiplegic type. Methods: A total of 100 children with cerebral palsy of spastic hemiplegia type were divided into a treatment group and a control group according to the visiting sequence, with 50 cases in each group. The control group was treated with conventional rehabilitation plus conventional acupuncture treatment. The treatment group was treated with conventional rehabilitation plus muscle regions of meridians needling method. The electromyography (EMG) signal values of triceps brachii and pronator teres were detected before treatment, and 3 months and 6 months after treatment. The clinical efficacy was evaluated by Peabody developmental motor scale-fine motor (PDMS-FM) and fine motor function measure (FMFM). Results: Three and six months after treatment, the EMG signal values of triceps brachii and pronator teres, grasping scores and visual-motor integrated scores of PDMS-FM and the FMFM scores in both groups increased to varying degrees compared with the same group before treatment, and the intra-group differences were all statistically significant (all P<0.05). Six months after treatment, the results of the above three items in the treatment group were all better than those in the control group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Muscle regions of meridians needling method added on the basis of conventional rehabilitation can effectively reduce the muscle tone of upper limb and enhance the muscle strength, and improve the upper limb function in children with cerebral palsy of spastic hemiplegia type. The efficacy is superior to that of the conventional rehabilitation plus conventional acupuncture treatment.
