Objective: To objectively evaluate the short-term and long-term efficacies of arthrolysis under brachial plexus anesthesia in treating adhesive capsulitis of the shoulder (ACS). Methods: One hundred patients diagnosed with ACS were divided into two groups using the random number method. The two groups both received same active rehabilitation exercises. Besides, 55 cases in the treatment group were given one session of arthrolysis under brachial plexus anesthesia, and 45 cases in the control group were given tuina treatment. Changes in the visual analog scale (VAS) score, Melle score and pressure pain index were observed 1 month and 3 months after treatment. The therapeutic efficacies were also compared. Results: The total effective rate was 96.4％ at the 1-month follow-up and 96.4％ at the 3-month follow-up in the treatment group. The total effective rate was 33.3％ at the 1-month follow-up and 28.9％ at the 3-month follow-up in the control group. There were significant differences between the two groups comparing the total effective rate at the two time points (both P<0.05). The scores of VAS, Melle and pressure pain were significantly different at the 1-month and 3-month follow-ups from those before treatment in the treatment group (all P<0.05); the three scores did not show significant differences at the 1-month and 3-month follow-ups compared with those before treatment in the control group (all P>0.05). Conclusion: Based on the active rehabilitation exercises, one session of arthrolysis under brachial plexus anesthesia can release the adhesion and restore the range of motion and function of shoulder joint in ACS patients. It is superior to rehabilitation exercises plus tuina treatment comparing both short-term and long-term efficacies.

Tripterygium glycosides preparation which extracted from the traditional Chinese herb Tripterygium wilfordii (TWHY), was widely used to treat the autoimmune diseases. Previous works demonstrated that TWHF had potent anti-inflammatory and immunosuppressive properties. But the different quality and high incident rate of side effects of different manufactures inhibited its clinical application. Since TWHF had been generally known to play a therapeutical effect by synergism of multiple constituents, it was necessary to build the relationship between the HPLC fingerprint and bioactivity so as to ensure the quality safety and efficacy. The HPLC fingerprint showed that description and content of peaks from different manufactures were diverse. Only 11 common peaks were found. In this study, mice spleen cells stimulated by Con A were used to test the proliferation inhibition bioactivity of TWHF preparations, which were incubated with 30, 15, 7.5, 3.75, 1.88 and 0.94 mg x L(-1) TWHF preparations for 48 h. The results showed that mice spleen cells proliferation was inhibited by all TWHF preparations significantly compared with the control group, which suggested the TWHF preparations showed immune suppress activity. The TWHF preparations from 7 manufacture showed different IC50 value, which might belong to different contents which showed in the HPLC fingerprint. Moreover, a relationship between the HPLC fingerprint and the bioactivity were established to identify important constituents by grey relational analysis (GRA). The result showed that all the contents were relative with the IC50, especially No. 5 and 10 peaks, but No. 1 peak, which was proved to be triptolide, had few contribute to the inhibition of mice spleen cells proliferation. The study of relationship between the HPLC fingerprint and the IC50 by GRA could help to investigate mechanism of bioactive and provide an evidence for the quantification of multi-constituents.

OBJECTIVETo study the genetic diversity of HIV-1 nef genes from a patient with AIDS dementia complex(ADC) , so as to research the amino acid variability and the pathogenesis of ADC.

METHODSThe nef gene was amplified with PCR from genomic DNA which was extracted from spleen and different brain tissues(basal ganglia, frontal gray matter, meninges, temporal lobe)of a patient who died of ADC. PCR products were cloned into the pMD19-T vector, after transformation and selection by ampicillin and blue/white spotting. Five of positive clones were sequenced and confirmed with BLAST. HIV-1 nef sequences were processed with BioEdit and MEGA4 to do Neighbor-Joining tree, p-Distances, and values of ds/dn.

RESULTSThe samples were all identified as HIV-1 B and genetic variation exists in HIV-1 nef gene isolated from different tissues compared with HXB2. In addition,part of the changes were different between periphery and brain.

CONCLUSIONVariations exist in the HIV-1 nef gene extracted from the ADC patient and the variations from peripheral and central nerve tissues were different,these variations may change the function of Nef,and it needs more research.

OBJECTIVESTo identify serum biomarkers associated with early gastric cancer.

METHODSSerum proteins or peptides were purified with weak cation exchange magnetic beads in 433 patients with gastric cancer and 120 healthy subjects. Distinct peaks were selected using Biomarker Wizard software. The area under receiver operating characteristic curve(AUC) was generated to analyze discrimination capability of peaks between gastric cancers and health people.

RESULTSThirteen distinct peaks were identified between 42 gastric cancer and 42 health people matched by age and gender(P<0.001). There were 5 peaks (2745, 2768, 6629, 3402, and 6436 m/z) with AUC greater than 0.8. Peak of 6629 m/z was identified to be transthyretin. The sensitivity and specificity of 6629 m/z were 65.5% and 92.0%. The sensitivity of 6629 m/z was 59.4% in I(A gastric cancer.

CONCLUSIONTransthyretin precursor may be of value in the early diagnosis of gastric cancer.

OBJECTIVETo screen the carcinogenesis associated genes in gastric carcinoma by gene chip.

METHODSU133A (Affymetrix Santa Clara, CA) gene chip was used to detect differentially expressed genes in tumor tissues, paratumor mucosa and normal mucosa. Bioinformatics was used to analyze the screened results.

RESULTSA total of 150 genes were detected with a difference of expression levels more than 3 times in paratumor mucosa compared with normal gastric mucosa, 130 of which were up-regulated and 20 down-regulated. According to the function classifications of the differentially expressed genes, the most common ones were enzyme and enzyme regulon activity associated genes(28, 18.7% ). The frequencies of nuclei acid binding activity associated genes,signal transduction associated genes and protein binding associated genes were 11.3%, 10%, and 8.7% respectively. Seventy-one differentially expressed genes were detected both in tumor tissues and paratumor mucosa compared with normal mucosa, 61 of which were up-regulated and 10 down-regulated. Among these 71 genes,e leven genes were localized on chromosome 19, 6 on chromosome 1, 2, 16, 17 respectively. No abnormal differentially expressed gene were detected on chromosome 5, 14, 22 and Y.

CONCLUSIONSThese 71 genes differentially expressed both in tumor tissues and paratumor mucosa may be associated with carcinogenesis of gastric carcinoma. The four kinds of genes associated with enzyme and enzyme regulon activity, nuclei acid binding activity, signal transduction, and protein binding should be the main genes for the study of carcinogenesis in gastric carcinoma.
