Objective To explore the composition and distribution law of TCM syndromes in gastric cancer. Methods Based on the multicenter and large-sample clinical epidemiological investigation, the four methods of diagnosis of and clinical materials of 767 cases of gastric cancer were collected, and the database of TCM syndromes in gastric cancer was establish. Factor analysis and clustering analysis were used to explore composition and distribution law of TCM syndromes in gastric cancer. Results Gastric cancer symptoms mainly included fatigue, weight loss, dizziness and other non-specific systemic manifestation, and epigastria discomfort, belching, fullness or eating just a little swelling, pain, acid regurgitation, loss of appetite and other local manifestations. At the same time, the red tongue, moss greasy, pulse fine or string and other traditional Chinese medicine signs were also included. Eliminating 92 cases with too little symptoms, 675 cases were under multivariate analyzed. 25 syndrome variables were selected after initial factor analysis, again through factor analysis 10 factors with eigenvalues more than 1.0 were obtained and the cumulative contribution rate was 60.5%. Through further K-means clustering analysis on 10 common factor integrals, it was found that when all the cases were clustered into 7 classes consistent with clinical practice most. The numbers of patients with the 1-7 type were 165, 82, 90, 79, 88, 95 and 76, respectively. Analysis on the main factors in the combination of professional knowledge, the 7 types were named as the syndrome of spleen and stomach qi stagnation (24.44%), the syndrome of qi and blood deficiency (12.15%), the syndrome of spleen deficiency (13.33%), the syndrome of blood stasis (11.70%), the syndrome of phlegm dampness (13.04%), the syndrome of deficiency cold of spleen and stomach (14.07%), the syndrome of incoordination between liver/gallbladder and stomach (11.41%) respectively. Conclusion The results of multivariate analysis suggests that the location of gastric cancer is in the stomach, and closely related to spleen, liver and gallbladder. The general pathogenesis is asthenia in origin and asthenia in superficiality. The deficiency lies in qi, blood and yang qi, while asthenia superficiality owes to stagnation of qi, phlegm and blood stasis.

It is an important task to lab of clinical microbiology to surveille multi-drag or pan-drug resistant strains,such as penicillin-or macrolide-resistant Streptococcus pneumoniae,methicillin-resistant Staphylococcus aureus(MRSA),3rd generation cephalosporin-or quinolone-resistant Enterobacteriaceae, carbapenem-resistant Pseudomonas aeruginosa or Acinetobacter baumannii,and so on.We must understand characteristics of these resistant strains to guide doctors' empirical therapy of infective diseases.

OBJECTIVETo study the influecnce of gentian leaf blight on the output and quality of rough gentian.

METHODThe same grade seedlings were transplanted, disease of every plant was investigated in autumn and the output of gentian was determined. HPLC was applied to determine the content of gentiopicroside and swertiamarin.

RESULTThe output decreased with the aggravation of the disease, and the decrease was obvious when the index of disease was above 60. The content of gentiopicroside and swertiamarin began to drop when the index of disease was above 70.

CONCLUSIONThe loss of output and the drop of quality are relatively heavy when the disease is serious. The loss of income is not obvious when the index of disease is under 60.

Objective To investigate the in vitro antimicrobial activity of ampicillin-sulbactam,clindamycin and cefoperazone a- gainst common clinical isolates.Methods MICs of these three antibiotics were determined by E test.Results Ampicillin-sulbae- tam showed inhibition rate of 100% for methicillin susceptible S.aureus (MSSA),E.faecalis,Group A Streptococcus,H. influenzae,penicillin-susceptible S.pneumoniae (PSSP),M.catarrhalis and anaerobes (including 10 strains of Bacteroid spp.,2 strains of P.aches,1 strain of E.lentum,1 strain of Fusobacterium innocuum,and 2 strains of Peptostreptococcus spp.).Ampicillin-sulbactam was active against 86.7% of extended-spectrum?-lactamase non-producing K.pneumoniae (NES- BL-KPN) and 53.3% of non ESBL-producing E.coli (NESBL-ECO).Ampicillin-sulbactam only inhibited 23.3% of A.bau- mannii isolates and 25.0% of E.faecium isolates.For MSSA,anaerobes,PSSP and group A Streptococcus,about 60.0%, 31.2%,30.0% and 10.0% of the isolates were susceptible to clindamycin,respectively.For MSSA,NESBL-ECO and NES- BL-KPN,96.7% to 100% of the isolates were susceptible to cefoperazone.About 40.0% of P.aeruginosa isolates were sus- ceptible to cefoperazone.No A.baumannii isolate was susceptible to cefoperazone.Conclusions The ampicillin-sulbactam has good antimicrobial activity against MSSA,E.faecalis,Group A Streptococcus,NESBL-KPN,H.influenzae,PSSP,M.ca- tarrhalis and anaerobes.In this study,clindamycin is active against 60% of MSSA isolates.Most of other species are relatively resistant to clindamycin.Cefoperazone shows good activity against MSSA,NESBL-ECO,and NESBL-KPN.These three anti- microbial agents can be used as empirical treatment for community-acquired infections.

Endoplasmic reticulum stress (ERS) is an adaptive process in response to circumstantial changes, but excessive and/or prolonged ERS can induce cell apoptosis. C/EBP homologous protein (CHOP) is a very important marker participating in ERS-associated cell apoptosis, while the role of the myocyte apoptosis induced by CHOP remains unclear in the development of hypertrophy. The present study aimed to investigate the effect of CHOP-mediated ERS-associated apoptosis on myocardial hypertrophy induced by abdominal aortic constriction in rats. Healthy male Wistar rats were randomly divided into model group (n=45) and control group (n=40). The rats in model group received abdominal aortic constriction. Hemodynamic changes, whole heart weight/body weight (HW/BW) and left ventricular weight/body weight (LVW/BW) were measured on 1 d, 3 d, 7 d, 14 d and 28 d after surgery, respectively. The mRNA expression of glucose-regulated protein 78 (GRP78), calreticulin (CRT) and CHOP, which are important markers of ERS, were detected by RT-PCR, and Western blot was used to assess the protein level of GRP78, CRT, CHOP, and apoptosis-associated proteins, Bax and Bcl-2. The results obtained were as follows. Compared with control group, the blood pressure, LVW/BW, and HW/BW of rats in model group increased significantly and cardiac function enhanced compensatively on 7 d after surgery, and increased progressively during the experiment. As early as 1 d after surgery, the mRNA level of CRT in model group increased by 136% (P< 0.01) compared with control, while the protein expression increased by 69.2% on 7 d after surgery (P<0.01). Both mRNA and protein expression of GRP78 increased by 20% and 186% (P<0.01) respectively on 7 d after surgery, and the expression sustained high level during the experiment afterwards. Correlation analysis indicated a positive correlation between +dp/dt(max) and CRT protein expression (r=0.780, P<0.01) as well as GRP78 protein expression (r=0.694, P<0.01). Prolonged ERS triggered myocyte apoptosis, as both the mRNA and protein level of CHOP in model group increased by 22.2% (P<0.01) and 76.0% (P<0.01) respectively compared with control on 7 d after hypertrophy (14 d after surgery), and meanwhile, the protein expression of pro-apoptotic Bax increased by 41.1% (P<0.01) and anti-apoptotic Bcl-2 protein expression decreased by 25.5% (P<0.01). Correlation analysis indicated a positive correlation between CHOP and Bax expression (r=0.654, P<0.01), and a negative correlation between CHOP and Bcl-2 expression (r=-0.671, P<0.01). These results suggest that abdominal aortic constriction induces a significant up-regulation in ER molecular chaperones at early stage of post-surgery, indicating that ERS response is activated in the rat heart; while prolonged ERS could lead to myocyte apoptosis, and CHOP-mediated ERS-associated apoptosis may contribute to myocardial hypertrophy. We speculate that cell apoptosis may take part in the regulation of myocardial hypertrophy and heart failure, and determine the progression of decompensated hypertrophy.
