To improve the antibiotics production of Streptomyces qinlingensis sp. nov.,protoplast regeneration combined with physical and chemical mutagenesis was used to selected high-yielding strains. The results showed that the antibacterial activities of strain R-72 from protoplast regeneration and NTG-1,H30-7 from protoplast mutagenesis against Bacillus subtilis were more than 20% higher than that of the original strain,and the heredity characters of those strains were stable in successive ten generations. The further bioassay experiments exhibited that the fungicidal and antibacterial activities of the fermentation broth from R-72,NTG-1 and H30-7 were remarkable increased comparing with that of the starting strain.

Objective To understand clinical distribution and antimicrobial resistance of clinically isolated Serratia marcescens(S .marcescens ),and provide basis for rational use of antimicrobial agents,as well as prevention and control of infection.Methods 427 S .marcescens strains isolated between January 1 ,2012 and December 31 ,2015 were analyzed,antimicrobial susceptibility testing were performed by disk diffusion method.Results 427 S . marcescens strains were mainly from respiratory tract (70.26%),among which the majority were from sputum (64.87%).S .marcescens were primarily from intensive care unit(ICU,19.44%),department of integrated tradi-tional Chinese and Western medicine(15.46%)as well as rehabilitation department (13.58%).The resistance rates of S .marcescens to cefoperazone/sulbactam,ertapenem,cefepime,ceftazidime,amikacin,imipenem,levofloxacin, and piperacillin/tazobactam were all<10%;resistance rates to ciprofloxacin,gentamicin,tobramycin,ceftriaxone, sulfamethoxazole/trimethoprim (SMZ/TMP),and aztreonam were 10%-30%.Difference in the resistance rates of S .marcescens to cefoperazone/sulbactam,ciprofloxacin,ceftriaxone,amikacin,aztreonam,and SMZ/TMP dur-ing 4 years were statistically significant (P <0.05).In 2012-2013,resistance rates of S .marcescens to cefopera-zone/sulbactam,ciprofloxacin,ceftriaxone,aztreonam,and SMZ/TMP increased obviously,then resistance rates tend to be stable,while resistance rates to cefoperazone/sulbactam decreased.Conclusion Susceptibility of S.marcescens to most antimicrobial agents are high,but resistance had increasing tendency;susceptible rates of S .marcescens to ertapenem,ceftazidime,levofloxacin,and piperacillin/tazobactam are all high,and can be used as the empirical medication for the treatment of related infection.

OBJECTIVE: To investigate the immunoregulation and short-term therapeutic effects of super-selective intra-arterial chemotherapy combined with Fuzheng Kang'ai Granules, a compound Chinese herbal medicine, on patients with late gastric cancer. METHODS: Forty patients with late gastric antrum cancer were randomly divided into study group and control group. Patients in the study group were orally administered Fuzheng Kang'ai Granules 48 hours after the first super-selective left gastric artery chemotherapy with high-dose drugs (EAP regime: VP(16) 100 mg/m(2) + epirubicin 60 mg/m(2) + carboplatin 200 mg/m(2)), while patients in the control group were only administered the same local artery chemotherapy as in the study group. RESULTS: The short-term therapeutic efficacy in the study group and control group were 82.5% and 57.5% respectively (P<0.01). The occurrence rates of side effects in the study group were significantly lower than those in the control group (P<0.01). The Karnofsky score of life quality of the study group was obviously higher than that of the control group after treatment (P<0.05). The half survival time and one year survival rate in the study group and control group were (24.9 +/- 1.36) month, 70% (28/40) and (13.7 +/- 0.72) month, 35% (14/40) respectively. They were significantly improved in the study group compared with the control group (P<0.01). The levels of cytokines interleukin 2 (IL-2), tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma) after treatment in the study group were significantly higher than those before treatment (P<0.05 or P<0.01), as well as than those after treatment in the control group (P<0.01). On the other hand, the level of immune inhibitory factor soluble interleukin-2 receptor (sIL-2R) after treatment in the study group was lower than that before treatment, as well as than that after treatment in the control group (P<0.01). CONCLUSIONS: The super-selective intra-arterial chemotherapy combined with Fuzheng Kang'ai Granules has good short-term therapeutic efficiency and few side effects for patients with late gastric antrum cancer. It can significantly improve the life quality, extend the survival period, and improve the survival rate in patients with late gastric antrum cancer, which may be due to the up-regulation of the immune regulating factors such as IL-2, TNF-alpha, IFN-gamma and down-regulation of the immune inhibitory factor sIL-2R.

Objective To evaluate the clinical efficacy of acupuncture at Baihui (GV 20) and Shenting (GV 24) in treating post-stroke cognitive impairment (PSCI) by using the systematic review method.Method Via computer, Chinese Journal Full-text Database (CJFD), Wanfang, China Biology Medicine disc (CBMdisc), Chinese Science and Technology Periodical Database, PubMed, Foreign Evidence-Based Medicine (FEMB), the Cochrane Library were retrieved.Chinese Acupuncture and Moxibustion andShanghai Journal of Acupuncture-moxibustion were manually retrieved. Randomized controlled trials published before Jan 31st of 2013 on acupuncture at Baihui (GV 20) and Shenting (GV 24) in treating PSCI, both in Chinese and English, were collected. The required data were extracted, then were evaluated according to the criteria of Cochrane systematic review and underwent meta-analysis by using RevMan 5.0.Result Twenty-two clinical trials were finally recruited, including 1637 subjects. The meta-analysis showed that acupuncture at acupoints including Baihui (GV 20) and Shenting (GV 24) produced a more significant rehabilitation result compared to single rehabilitation training or medication. The comparison of Mini-Mental State Examination (MMSE) score showed: [WMD=3.37, 95％CI (1.70, 5.05),P<0.00001]; the comparison of P300 latency: [WMD=1.22, 95％CI (0.84, 1.59),P<0.00001]. Severe adverse reactions were not discovered. Conclusion Acupuncture at Baihui (GV 20) and Shenting (GV 24) can effectively improve the cognitive function of PSCI patients. However, the diagnostic criteria and evaluation indexes are expected to be unified and standardized, and the clinical trials on acupuncture intervening PSCI are required to be further improved methodologically.

Field studies were conducted for a season to determine potential for alterations in the rhizosphere fungi quantity dynamics and dominant populations of 4 wild sugarcane clones(S.spontaneum L.) with different UV-B sensitivity under an enhanced ultraviolet-B(UV-B,280 nm～310 nm) radiation.The quantity of rhizosphere fungi was most in tillering stage,second in seedling stage and lest in elongating stage and maturing stage,the sequence wasn’t alternated by UV-B radiation.The rhizosphere fungi quantity of tolerant clone was obviously increased and greater than the sensitive clone under the enhanced UV-B radiation,however,the number of dominant populations decreased and Penicillium was the dominant population during the periods of 4 wild sugarcane clones.

Objective To study the clinical significance of the serum angiopoietin-2(Ang-2) in the diagnosis,recurrence,invasion and metastasis of gastric cancer.Methods The serum Ang-2 and carcino-embryonic antigen (CEA) levels in 158 patients with gastric cancer (gastric cancer group) and 30 normal controls(control group) were measured by enzyme linked immunosorbent assay(ELISA) technique respectively.The serum Ang-2 and CEA levels were also measured 2 weeks after operation in gastric cancer group and reexamined in the recurred gastric cancer patients in 2 years after operation (recurred and metastasis group).The correlation between the serum Ang-2 level and pathologic c haracterization of gastric cancer was evaluated.Results The serum Ang-2 and CEA levels in gastric cancer group [ (331.8 ±64.3),(42.6 ±37.3)μg/L] and recurred and metastasis group [(318.7 ±72.9),(40.5 ±36.7)μg/L] were significantly higher than those in control group [ (187.4 ± 32.7),(4.2 ± 3.1 )μ g/L] (P ＜ 0.01 ),and the serum Ang-2 level 2 weeks after operation [ (211.6 ± 75.1 ) μ g/L ] was significantly decreased to the control group (P ＞ 0.05 ),while the serum CEA level [ (33.4 ± 30.6) μ g/L ] was still significantly higher than the control group (P ＜ 0.01 ).The sensitivity of the serum Ang-2 for diagnosis of gastric cancer was markedly higher than that of the serum CEA (P ＜ 0.01 ).There was correlation between serum Ang-2 and degree of tumor differentiation,TNM pathological staging,lymphatic metastasis,invasion depth and tumor size (p ＜0.01 ),but there was no correlation between serum Ang-2 and tissue classification and location of gastric cancer (P＞ 0.05).Conclusion The serum Ang-2 level is suggested to be a valuable gastric cancer marker and conduce to the diagnosis of gastric cancer,the monitoring of recurrence after operation and evaluation of prognosis.
