OBJECTIVETo observe the clinical effect of Guilu Erxian Glue Cataplasm (GEGC) on carcinoma of the large intestine patients with myelosuppression after chemotherapy, and further to confirm its efficiency and safety.

METHODSTotally 60 patients with carcinoma of the large intestine were randomly assigned to two groups. Meanwhile, they all accepted FOLFIRI chemotherapy. Patients in the treatment group were additionally applied at Shenque (RN8), exchanging once per every other day, for 14 successive days. Patients in the control group took placebos with the same dose and dosage as the treatment group. The blood cell counts (WBC, NE, and PLT) were detected before chemotherapy, at day 7, 10, and 14. The TCM symptoms integrals, Karnofsky performance score (KPS), liver and kidney functions were observed before chemotherapy, at day 7 and day 14. Adverse skin reactions were observed each day. And the usage of hematopoietic growth factors was recorded.

RESULTS(1) The KPS score at day 7 was more stable in the treatment group than in the control group; the WBC and NE counts in the peripheral blood at day 14 were higher in the treatment group than in the control group; and TCM symptoms integrals at day 14 was lower in the treatment group than in the control group, all with statistical difference (P < 0.05). (2) Compared with the control group, the PLT count was higher in the treatment group than in the control group, the usage of rhG-CSF and antibiotics was less in the treatment group than in the control group, all with no statistical difference (P > 0.05). (3) No obvious adverse reactions such as liver injury, renal injury, or skin allergy were observed.

CONCLUSIONSAdjuvant treatment of GEGC could improve carcinoma of the large intestine patients with myelosuppression to some extent. No relevant adverse reactions were found.

This study aimed to investigate the synergistic effect of lidamycin (LDM) and rituximab on human B cell lymphoma Ramos cells. Cell proliferation was measured using MTS assay, cell apoptosis was analyzed by Annexin V-FITC/PI assay, the expression of apoptosis related proteins was analyzed by Western blotting, and the in vivo lymphoma inhibition was verified using BALB/c mice inoculated via tail vein using Ramos cells which stably expressed pEGFP-N1 plasmid. The results showed that, after the pretreatment with rituximab for 48 h, rituximab and LDM showed significantly synergistic effects on cell proliferation. Cells in combined treatment group had a higher apoptosis rate than that in LDM treatment group. Compared with the LDM treatment group, the expression of apoptosis-related proteins such as Cleaved caspase-3, Cleaved caspase-7, Cleaved caspase-9 and Cleaved PARP in combined treatment groups increased, and expression of cIAP-2 and Bcl-2 decreased. The result of in vivo experiment showed that, in the combined treatment group, the survival time of BALB/c mice was significantly longer than the mice in control group and LDM treatment group, and the degree of tumor accumulation and metastasis to lymph nodes and spleen was lower.

OBJECTIVETo explore the repair of Xiangsha Liujunzi Decoction (XSLJZD) on interstitial cells of Cajal (ICC) and gap junction (GJ) in the gastric muscular layer of rats of Pi-qi deficiency syn- drome (PQDS).

METHODSPQDS was established using purgative method with bitter and cold drugs in 30 healthy Wistar rats. After successful modeling they were randomly divided into the treatment group and the model group, 15 in each group. Another 15 healthy Wistar rats were recruited as the healthy control group. Rats in the treatment group were gastric administered with XSLJZD at 2 mL/100 g body weight, once daily for 14 successive days. Equal volume of normal saline was gastrically administered to those in the healthy control group and the model group. The gastric muscle tissues were taken out before modeling, before intervention, and after intervention, respectively. Ultrastructural changes of ICC and GJ were observed using transmission electron microscope (TEM). The number and distribution of Connexin43 (Cx43) were detected using immunohistochemistry.

RESULTSResults of TEM indicated that compared with the healthy control group, both ICC and GJ in the model group showed obvious injury. ICC and GJ were apparently repaired after intervention in the treatment group. Compared with the same group before modeling, the integrated optical density (IOD) of the Cx43 expression significantly decreased in the model group before and after intervention (P <0.05). Compared with before intervention, the IOD of the Cx43 expression significantly increased in the treatment group (P <0.05). Compared with the healthy control group, the IOD of the Cx43 expression significantly decreased in the model group before and after intervention (P <0.05). Compared with the model group, the IOD of the Cx43 expression significantly increased in the treatment group (P <0.05).

CONCLUSIONSUltrastructures of ICC and GJ in the gastric muscular layer of rats of PQDS were obviously damaged. XSLJZD could repair the structural damage of ICC and GJ in the gastric muscle tissues of rats of PQDS.

It is extremely necessary and important for colleges or universities to transform the education concepts that barricade students' initiative and creativity, especially the one that takes fi-nal examinations as sole standard to evaluate teaching and learning effects. In order to display and cultivate students' study ability more comprehensively, we manage to establish a set of formative eval-uation system for regional anatomy course , which involves tests and examinations and evaluations throughout the whole teaching and learning process. It solves the long-lasting problem that examina-tions are final purposes of teaching and learning, and thus, teaching values not only results but also learning process, which directs students' attention to conventional studies and helps develop good study habits, greatly reducing the randomness of final academic performances. The diverse assessment methods, along with accumulated assessment results, can improve students' learning effects through-out the whole semester. The fundamental purpose of this system is to inspire students' passion for study and creativity and monitor the teaching process.

Objective To investigate the antimicrobial resistance of clinical isolates in Tongling People′s Hospital during 2013. Methods A total of 2 281 nonduplicate clinical isolates were collected.Kirby-Bauer disc diffusion method was employed to study the antimicrobial susceptibility.The data were analyzed with WHONET 5.6 software according to CLSI 2012 breakpoints. Results The top 5 most frequently isolated microorganisms were E.coli (479,21.0%),K.pneumoniae (360,15.8%),A. baumannii (271,11.9%),P .aeruginosa (240,10.5%),S.aureus (171,7.5%).Gram negative and gram positive microorganisms accounted for 76.5% and 23.5%,respectively.The prevalence of methicillin-resistant strains in S.aureus (MRSA)and coagulase negative Staphylococcus (MRCNS)was 38.6% and 73.1%,respectively.The resistance rates of MR strains to beta-lactams and other antimicrobial agents were much higher than those of MS strains.No staphylococcal strain was found resistant to vancomycin or teicoplanin.E.faecalis showed relatively lower resistance to penicillin,ampicillin and nitrofurantoin.E.faecium strains were more resistant than E.faecalis to most of the antibiotics tested.Approximately 50.5% of E.coli and 44.5% of Klebsiella isolates produced extended-spectrum beta-lactamases (ESBLs).The ESBLs-respectively.And 29.8% and 23.4% of the P .aeruginosa strains were resistant to imipenem and meropenem.Nearly all (94.0%)P .aeruginosa isolates were susceptible to amikacin.Conclusions There appears a trend of increasing resistance in the clinical bacterial isolates in this hospital,especially the carbapenem-resistant Enterobacteriaceae,which is of great concern.It is mandatory to take effective antibiotic policy and infection control measures.

AIM: To construct E. coli expression plasmid of recombinant human NDPK-A with a 6?His tag, optimize the expression condition and identify the activity of the product. METHODS: nm23-H1 was subcloned from plasmid pBVNMH1 to pQE40 which contain 6?His purification tag. The expression condition was modulated in grades to get the optimal expression. We purified protein with the Ni+-NTA affinity chromatography column, identified the immunogenicity of the product with Western blot, and measured the kinases activity with HPLC. In addition, angiogenesis inhibition activity of rhNDPK was identified by CAM. RESULTS: The sequence of nm23-H1 subclone in pQE40 was exactly correct. The expression rate of rhNDPK-A was 49 6%. Purified rhNDPK-A specially recognized the antiserum of NDPK-A. It also inhibited angiogenesis. CONCLUSION: PQE-nm23H1 containing 6?His can express target protein at high level. This purification method is simple than other methods, and the product has the same activity as natural human NDPK-A.
