Objective To study the production of ?-lactamase in multidrug-resistant Pseudomonas aeruginosa and to guide the proper use of antibiotics in clinical practice. Methods The modified three-dimensional extract test was employed to detect ?-lactamase in 30 multidrug-resistant Pseudomonas aeruginosa strains screened from antimicrobial susceptibility test in our hospital,and isoelectric focusing electrophoresis was performed on the enzyme-producing strains. Results No metalloenzyme was detected in all the 30 strains.Twenty-six strains produced ?-lactamase,among which 25 continuously yielded large amount of AmpC enzyme and the other one both AmpC enzyme and extended-spectrum ?-lactamases(ESBLs).86.7% of multidrug-resistant Pseudomonas aeruginosa produced enzyme. ConclusionThe majority of the multidrug-resistant Pseudomonas aeruginosa in our hospital yielded large amount of AmpC enzyme in a continuous way.The modified three-dimensional extract test can eliminate some interference such as the decrease of outer membrane permeability and overexpression of efflux pump,facilitating the effective and accurate detection of ESBLs in Pseudomonas aeruginosa.

Objective To observe the clinical efficacy of ginger-partitioned moxibustion in treating myelo- suppression induced by chemotherapy for multiple myeloma (MM), and to discuss the effect of ginger-partitioned moxibustion in preventing and treating the adverse reactions of chemotherapy.Method Forty-four MM patients with myelosuppression induced by chemotherapy were randomized into a treatment group and a control group, 22 cases each. The treatment group was intervened by ginger-partitioned moxibustion, while the control group was intervened by oral administration of Leukogen tablets, both for 14 d. The white blood cell (WBC) count was observed before the treatment, on treatment day 7 and 14, and 1 week after the intervention; the incidence of nausea and vomit and clinical efficacies were compared between the two groups.Result The total effective rate was 81.8% in the treatment group versus 63.6% in the control group, and the difference was statistically significant (P<0.05). The WBC count on the 7th treatment day was significantly different from that before the treatment in both groups (P<0.05); the WBC count in the treatment group was significantly different from that in the control group on the 7th treatment day (P<0.05). The WBC count on the 14th treatment day was significantly different from that on the 7th day in both groups(P<0.05); the WBC count in the treatment group was significantly different from that in the control group on the 14th treatment day (P<0.05). The WBC count 1 week after the treatment was insignificantly different from that on the 14th treatment day in both groups (P>0.05); there was no significant difference in comparing the WBC count 1 week after the treatment between the two groups (P>0.05). The incidence of nausea and vomit in the treatment group was significantly lower than that in the control group after the treatment (P<0.05).Conclusion Ginger-partitioned moxi- bustion can effectively treat myelosuppression due to chemotherapy for MM, and it can significantly increase the WBC count.

Objective To find out prevelence of thyroid goiter on school-aged children in excessive iodine region of Shandong Province.Methods By employing B-ultrasonography and palpation method,the thyroid volume were investigated and the thyroid goiter rate were calculated among 6415 children aged 8～10 years old in execssire iodine region.Results By employing B-ultrasonography method.The volumes of thyroid in goiter children aged 8,9,10 years were(5.67±1.49),(6.07±1.24),(7.30±2.01)ml,respectively.The goiter rates were 28.84%(683/2368),20.89%(448/2144),11.82%(225/1903).The volumes of thyroid in non-goiter children aged 8,9,10 years were(3.36±0.67),(3.64±0.77),(4.02±0.94)ml.When the normal value of thyroid volume in 8 and 9 year-groups lowered 0.5 ml,the goiter rate would be changed to 18.20%(430/2368)and 12.92%(277/2144) respectively.The thyroid volumes of boys and girls were(4.20±1.38),(4.18±1.73)ml,respectively.The goiter rates of boys and girls were 21.92%(732/3340)and 20.29%(624/3075)respectively.The rates of goiter detected by palpation in 8,9 and 10 year-groups were 10.05%(238/2368),10.31%(221/2144)and 14.45%(275/1903) respectively.Conclusions Along with the increasing age,the volume of thyroid in children aged 8～10 is increasing in excessive iodine region of Shandong Province.But the goiter rate is decreasing ahmg the increasing age.This phenomena may be caused by improper normal value of thyroid volume.Therefore,the normal value of thyroid volume should be revised urgently.

Objective To systematically assess the relation between angiotensin-I converting enzyme(ACE) gene insertion/deletion (I/D) variation and type 2 diabetic nephropathy (T2DN) onset risk among Chinese population.Methods The related literatures were retrieved from the China National Knowledge Infrastructure (CNKI) and Wanfang Data until June 1st,2016.The RevMan 5.0 was used to conduct the statistical analysis.The merge OR value and corresponding 95% confidence interval(95%CI) were used to assess ACE gene I/D polymorphism and T2DN onset risk.Results Totally 29 papers with 4 357 subjects were included according to the inclusion and exclusion standard,including 2 208 cases of DN and 2 149 cases of T2DM without DN.Meta analysis showed that compared with ACE gene I/D polymorphism I allele,D allele could significantly increase the risk of T2DM patients suffering from DN,the OR value and corresponding 95%CI were 1.44(1.25,1.66);the gene analysis showed that ACE gene I/D polymorphism loci were significantly correlated with DN onset risk in the Asian population.The corresponding relative onset risk OR and 95%CI were 1.42(1.15,1.76) and 1.75(1.46,2.10) in the dominant and recessive genetic model.The Begg′s test showed that the included data had no obvious publication bias existence.Conclusion ACE gene I/D polymorphism is closely correlated with the onset risk of T2DN,and D allele might be a risk genetic factor for DN occurrence in the patients with T2DM.

BACKGROUND: Total hip replacement in middle-aged patients is challenging regarding restoration and survival,because these patients are more active than old patients.OBJECTIVE: To retrospectively investigate whether a cementless prosthesis could restore hip function,decrease osteolysis,wear,and enhance prosthesis survival in middle-aged patients.METHODS: Clinical and radiological evaluations of patients undergoing single-side total hip replacement with cement and cementless prosthesis were analyzed preoperatively as well as at 6 months,1,4 and 7 years postoperatively.The outcomes of total hip replacement were assessed using Harris hip scores and survival rate.End point was loosening or revision of the femoral component for any reason.RESULTS AND CONCLUSION: Cementless prosthesis had gained better Harris hip scores than that of cement prosthesis group at 6 months,1,4 and 7 years postoperatively(P < 0.05).The survival rate was greater in cementless prosthesis compared with cement prosthesis during 7-year follow-up(P < 0.05).Results have suggested that cementless prosthesis achieves high rate of functional restoration and a low rate of complications in middle-aged patients following total hip replacement.

In order to explore the scientific connotation of "Fangzhengduiying (formula corresponding to pattern types)", "Qiyinliangxuzheng (Qi and Yin deficiency pattern)" of myocardial ischemia rat model and GC-TOF/MS based metabonomic method were used for comparing the effects of Sheng-mai injection, Salvia injection and propranolol in the present study. After data processing and pattern recognition, Sheng-mai injection showed better efficacy than the other two drugs in accordance with not only visual observation from PLS-DA scores plots but also the number of abnormal endogenous compounds restored to the normal level. Further studies showed that Sheng-mai injection could normalize the level of plasma endothelin-1, the index related to cardiovascular diseases and sleep disorders, which verified the results of metabonomics. Finally, the regulated metabolites and related metabolic pathways were analyzed, and it was supposed that the effects of Sheng-mai injection involved in the alternation of energy metabolism, lipid metabolism, amino acids metabolism, and so on. These findings provided scientific evidence to Shengmai "Fang" used for "Qi and Yin deficiency pattern" correspondingly, indicating that metabonomics has great potential in traditional Chinese medical research, which provides a novel approach and way to modernization of traditional Chinese medicine.
