Objective To analyze the distribution rule of TCM syndromes and syndrome elements in chronic atrophic gastritis with osteoporosis by retrospective study method, and provide evidence for TCM treatment. Methods TCM symptoms, syndromes and syndrome elements of 127 cases of chronic atrophic gastritis with osteoporosis were retrospectively investigated and statistically analyzed. Results The distribution of TCM syndromes in chronic atrophic gastritis with osteoporosis was as follows:there were 51 cases of asthenia syndrome of both qi and yin, accounted for 40.16%;28 cases of yang deficiency syndrome of spleen and kidney, accounted for 22.05%;21 cases of syndrome of qi deficiency and blood stasis, accounted for 16.54%. The distribution of syndrome elements was:there were 82 cases of qi deficiency, accounted for 64.57%;61 cases of yin deficiency, accounted for 48.03%;28 cases of yang deficiency, accounted for 22.05%;21 cases of blood stasis, accounted for 16.54%;12 cases of qi stagnation, accounted for 9.54%;6 cases of dampness-heat, accounted for 4.72%. Conclusion The basic pathogenesis of chronic atrophic gastritis with osteoporosis is deficiency of both spleen and kidney. Deficiency of kidney is mainly qi deficiency, yin deficiency, yang deficiency, or even deficiency of both yin and yang. Reinforcing spleen and kidney is the important principle of treatment.

Objective To explore the effects of Yishen-Jianpi decoction on bone mineral density (BMD) and serum sclerostin level in chronic atrophic gastritis in rats. Methods Wistar rats were randomly divided into normal control group, model group, Weimeisu group, low-, medium-and high-dose Yishen-Jianpi Decoction groups. Chronic atrophic gastritis was induced via depriving of water by replacement with 0.1%ammonia water for 180 days. After modeling, the rats in the Yishen-Jianpi decoction groups of low-, medium-and high-dose received intragastric administration of Yishen-Jianpi decoction of 7.5, 15, 30 g/(kg?d), respectively;the Weimeisu group received intragastric administration of Weimeisu suspension 0.28 g/(kg?d);the normal control group and the model group received intragastric administration of equivalent volume of normal saline. After 90 d continuous administration the specimens were drawn. The femur BMD and BMC were detected with dual energy X-ray absorptiometry. The serum sclerostin level was measured with enzyme-linked immunosorbent assay. The serum levels of parathyroid hormone (PTH) and human calcitonin (CT) were detected with radioimmunoassay. Results Compared with the normal control group (n=10), the femur BMD (0.168 ± 0.007 g/cm2 vs. 0.235 ± 0.029 g/cm2), BMC (0.383 ± 0.022 g vs. 0.637 ± 0.085 g), and the serum CT level (26.76 ± 11.54 pg/m vs. 33.85 ± 13.12 pg/ml) in the model group (n=9) were significantly decreased (all P<0.05), while the serum level of sclerostin (105.78 ± 34.43 pg/ml vs. 71.51 ± 23.21 pg/ml) and PTH (11.52 ± 4.34 ng/dl vs. 8.46 ± 2.39 ng/dl) were significantly increased (all P<0.05). Compared with the model group, the femur BMD (0.197 ± 0.011 g/cm2, 0.201 ± 0.017 g/cm2, 0.206 ± 0.021 g/cm2 vs. 0.168 ± 0.007 g/cm2), BMC (0.538 ± 0.036 g, 0.546 ± 0.039 g, 0.569 ± 0.048 g vs. 0.383 ± 0.022 g), serum CT level (30.42 ± 12.61 pg/ml, 31.35 ± 12.75 pg/ml, 30.83 ± 13.10 pg/ml vs. 26.76 ± 11.54 pg/ml) in the Yishen-Jianpi decoction groups of low-(n=10), medium-(n=10) and high-dose (n=9) were significantly increased (all P<0.05), while serum levels of sclerostin (86.32 ± 24.28 pg/ml, 87.65 ± 24.75 pg/ml, 86.82 ± 25.56 pg/ml vs. 105.78 ± 34.43 pg/ml) and PTH (9.36 ± 2.76 ng/dl, 9.76 ± 2.85 ng/dl, 9.84 ± 2.97 ng/dl vs. 11.52 ± 4.34 ng/dl) were significantly decreased (all P<0.05). Conclusions Yishen-Jianpi decoction can reduce serum sclerostin level, and has protective effects against osteoporosis in chronic atrophic gastritis in rats.

Objective To observe the effects of Qutantongluo decoction on the expression of TGF-β1 in renal tissue of diabetic nephropathy(DN) rats,which can help to understand the mechanism of action.Methods The rats models of diabetic nephropathy were established by injecting with streptozotocin intraperi-toneally.All Wistar rats were randomly divided into 6 groups:the normal control group,the model control group,Benazepril Hydrochloridec group ( 1 mg/kg ·d-1 ),Qutantongluo decoction low dose group (3 g/kg ·d-1 ),Qutantongluo decoction median dose group (4.5 g/kg · d-1 ),and Qutantongluo decoction high dose group (6 g/kg · d-1 ).Rats in the normal control group and the model control group were given celiac perfusion of distilled water once at the same time and dose.All the rats were gavaged once daily for 8 weeks.The expression of TGF-β1 at the level of gene and protein in renal tissue were tested by immunohistochemistry and RT-PCR methods.Results Compared with the model control group(2.79±0.22),the expression of TGF-β1 at the level of protein in renal tissue of Benazepril Hydrochloridec group (1.55 ±0.12)and the Qutantongluo decoction low dose group ( 1.54± 0.16),Qutantongluo decoction median dose group (1.49 ± 0.17),Qutantongluo decoction high dose group(l.39±0.25) decreased significantly (P＜0.05).Compared with the model control group (0.35±0.07),the expression of TGF-β1 mRNA in renal tissue of Benazepril Hydrochloridec group(0.35± 0.07)and the Qutantongluo decoction low dose group(0.39±0.03),Qutantongluo decoction median dose group (0.35± 0.06),Qutantongluo decoction high dose group (0.32± 0.07) decreased significantly (P＜0.05).Conclusion Qutantongluo decoction can down regulate the expression of TGF-β1 in kidney,which may be one of the mechanisms of Qutantongluo decoction effectiveness in clinical treatment of diabetic nephropathies.

Objective To investigate the mechanism and epidemiological characteristics of carbap-enem-resistant Proteus mirabilis ( PM) strains deficient in swarming motility. Methods PM strains were isolated from Hangzhou General Hospital of CAPF ( Chinese People′s Armed Police Forces) during January 2013 to December 2014. Bacterial motility and flagella of the PM strains were observed through semi-solid agar culture and flagella staining. Pulsed-field gel electrophoresis ( PFGE) was performed for homology anal-ysis. Antimicrobial susceptibility test and phenotypic confirmatory test were also carried out. PCR analysis and DNA sequencing were performed to confirm the genotype of resistant genes. Plasmid electroporation and S1-PFGE in combination with Southern blot hybridization were used to determine the location of the carbap-enem-resistant genes. Genetic structure of the blaKPC-2 gene was obtained by PCR mapping. Results A total of 42 PM isolates deficient in swarming motility were screened out and the resistance rates to imipenem and meropenem were 57. 1% and 52. 4%, respectively. PCR analysis and DNA sequencing confirmed that 24 carbapenem-resistant PM isolates deficient in swarming motility carried blaKPC-2 gene and belonged to three clones as indicated by the results of PFGE. Southern blot hybridization indicated that the blaKPC-2 gene was located on plasmids varying in size (26 kb, 55 kb and 139 kb). In addition, some of the strains harbored several resistant genes, such as blaTEM-1 , blaCTX-M-65 and rmtB. The genetic structures of strains carrying blaKPC-2 gene were ISKpn8, blaKPC-2 and ISKpn6-like from upstream to downstream. Conclusion Compared with the PM strains with swarming motility, the carbapenem-resistance rate was significantly higher in these PM strains deficient in swarming motility. Carbapenemases KPC-2 played an important role in the carbapen-em-resistant PM strains deficient in swarming motility. There was a cloning spread trend for carbapenem-re-sistant PM strains in our hospital. Clinicians should pay more attention to the risk of spreading.

Objective To investigate antimicrobial resistance among gram-positive cocci in China in 2009. Methods From June to December 2009, 1169 consecutive and non-repetitive gram-positive cocci were collected from 12 teaching hospitals at 9 cities. The minimal inhibitory concentration (MIC) of antibacterial agents was determined by agar dilution method. Results The prevalences of methicillinresistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococci (MRCoNS) were 45.3% (211/466) and 89. 5% (214/239), respectively. The isolation rate of MRSA was 33. 3%-68. 1% from different samples. All Staphylococci isolates were susceptible to vacomycin, teicoplanin and linezolid. Five point five percent (7/128) E. faecium strains were resistant to vacomycin. All E.faecalis strains were susceptible to vacomycin. About 99. 1% (108/109) of E. faecalis and E. faecium were susceptible to linezoild. The prevalence of penicillin-intermediate Streptococcus pneumoniae (PISP) was 21.6% (48/222). Only 1 (0. 5%, 1/222) Streptococcus pneumoniae strain was resistant to penicillin.Teicoplanin, vancomycin, linezolid and tigecycline were the most active agents against Streptococcus pneumoniae (susceptible rate 100% ). Conclusions The high prevalence of methicillin-resistance is among Staphylococcus strains. Different samples show a different MRSA prevalence. Teicoplanin, vancomycin and linezolid show very high activity to Staphylococci,E. faecalis, E. faecium and Streptococcus pneumoniae.
