Ultrasonic is efficacious in curing bone injury.A suit of ultrasonic generator is developed for bone injury,which has a simple structure with good reliability.Besides the design principle and system scheme,the mechanism and application of ultrasonic therapy together with the key techniques such as wave-form producing,power adjusting and load coupling are analyzed.

There is still no agreed standard of care for CD30+ T-cell lymphomas which are dominant in peripheral T-cell lymphoma.The combination of multidrug or dose-intensified chemotherapy regimen and consolidation of hematopoietic stem cell transplantation are widely used at present.In recent years,several clinical trails included certain new agents,such as etoposide,alemtuzumab,denileukin diftitox,bortezomib,romidepsin,lenalidomide,brentuximab vedotin,and so on,have demonstrated the promising outcome.Referring targeted therapies for relapsed/refractory CD30 + T-cell lymphomas,certain agents have been approved,such as pralatrexate,romidepsin,brentuximab vedotin (ALCL),belinostat,and the most encouraging agent is brentuximab vedotin.

OBJECTIVE： To discuss the severe liver function damage induced by antituberculostics.METHODS： The severe liver function damage induced by antituberculotis was analyzed in 50 patients admitted into this hospital from January 1995 to January 2000.RESULTS： Sever liver function damage was related to the following factors:(1)history of liver diseases;(2)aged patient and malnutritional patient;(3)chronic alcoholism;(4)combined use of isoniazid,rifampin with other drugs;(5)hepatic dysfunction before treatment.CONCLUSION： The abovementioned factors should be under consideration in choice of antituberculotics.

Pancreatic cancer is one of the most lethal human malignant tumors, and its incidence is rising. Now, its treatment includes surgical resection,chemo - radiotherapy and supplementary treatment. The prognosis of pan-creatic cancer is still dismal. And its one-year survival is low. This article talks about the effect of clinical treatment on quality of life in patients with pancreatic cancer.

Pre-implantation Genetic Diagnosis(PGD) is an advanced technology based on in-vitro fertility-embryo transfer,which binds multiple-discipline arts,specially the research on DNA analysis assay of single cell,to reach the aim of aristogenesis and wash out abnormal embryo before transfer.With the development of this technique and the ever wider applications,ethical issues also arise.This paper focuses on these ethical issues related to PGD,expecting an actual benefit for human.

The paper tells how the authors' hospital managed under the circumstances of fierce competition in the medical market to integrate the idea of a marketing chain with medical service, construct a quality and efficient marketing chain for medical service, constantly readjust each part and element of the “chain management” of technical items and service manner, and realize multi layer and multi dimensional network management. The hospital also established a “chain management” framework characterized by “compliance with market laws, customers highest and delivery of quality service”. Setting on itself such high demands as “highest speed, best quality, lowest cost and optimal service”, the hospital did its best to create a strong marketing chain for medical service products, thus providing theoretical basis and practical reform experience for the marketing of medical service products.

Objective To find out the hygienic status of rural drinking water in Jianhe County of Guizhou Province.Methods Forty-eight source water and tap water samples from small centralized water supply stations in 12 townships of Jianhe County in dry season and wet period were tested from 2009-2011.The water samples were examined in accordance with the relevant provision of Standard Examination Methods for Drinking Water (B/T5750-2006).The contents included:①sensory indicators:standard color,turbidity,smell and taste and visible objects; ②general chemical indicators:pH,iron,manganese,chloride,sulfate,total dissolved solids,total hardness,oxygen consumption and ammonia; ③toxicological indicators:fluoride,arsenic and nitrate; ④microbial indicators:total number of colonies,with a total population of Escherichia coli and heat-resistant Escherichia coli Outcome evaluation was carried out in accordance with the Drinking Water Health Standards (B/T 5.749-2006).Results A total of 192 rural water samples were collected in 2009-2011,and 18 samples were qualified,accounting for 9.38％.The differences of water passing rate between groups of years were statistically significant (x2 =14.74,P＜ 0.01).Rural drinking water quality in dry season (18.75％,18/96) was better than that in wet season (0.00％,0/96; x2 =19.76,P ＜ 0.01).Passing rate of source water quality (16.67％,16/96) was higher than that of tap water(2.08％,2/96; x2 =11.95,P ＜ 0.01).Sensory indicators and toxicological indicators of 192 water samples were qualified.General chemical indicators:in addition to four water samples with pH exceeded the standard(two copies in 2009 and two copies in 2010),other test indicators were qualified.Microbiological indicators:passing rates of the total number of colonies,Escherichia coli group and heat-resistant Escherichia coli group were 77.08％ (148/192),9.90％ (19/192) and 20.31％ (39/192),respectively.Passing rate of microbes was 18.75％ (18/96) in dry season and 0.00％ (0/96) in wet period,and microbes passing rate was significantly higher in dry season than that of the wet period(x2 =19.76,P ＜ 0.01).Passing rate of microbes was 16.67％(16/96) in source water and 2.08％(2/96) in tap water,and passing rate of the source water was significantly higher than that of the tap water(x2 =11.95,P ＜ 0.01).Conclusions The hygienic status of rural drinking water in rural areas of Jianhe County of Guizhou Province is poor.Microbial pollution is the main reason.

砄bjective: To study the rule of the degradation of HA artificial bone(HAB). Methods: The samples of HAB were immersed in PBS or distilled water (DW),the changes of the shape, weight, compressive strength of the samples and pH value of the immersion solutions were measred at the intervals of 2 or 4 weeks until 28 weeks. Results: At 4 weeks, HAB began to be degraded, 8 weeks later, the speed of the degradation slowed down. From 4 to 12 weeks, the compressive strength decreased rapidly. The pH value of the immersion solutions decreased from 2 to 12 weeks,but increased from 12 to 28 weeks when it was close to the neutral value. Conclusion: HA artificial bone can be degraded in PBS solution, and the degradation can cause noticeable changes of the compressive strength of the material and pH value of the immersion solution.

Objective To investigate the relationship between genetic polymorphism of methylenetetrahydrofolate reductase (MTHFR) and the risk of childhood acute lymphocytic leukemia (ALL).Methods 45 patients with ALL and a cohort of 45 matched healthy children were included,and DNA was extracted from their peripheral blood.PCR-RFLP was used to determine the genotypes of MTHFR C677T and A1298C.The adjusted odds tatio (OR) and 95 ％ confidence interwal (CI) were calculated using unconditional logistic regression model.Results The frequency of MTHFR 677 CC,CT and TT genetypes were 31.1％ (14/45),51.1％ (23/45) and 17.7 ％ (8/45) in controls and 51.1％ (23/45),40.0 ％ (18/45) and 8.9 ％ (4/45)in ALL,respectively (x2 =7.48,P =0.04).The frequency of MTHFR 677 T allele were 69.9 ％ (31/45) in controls and 48.8 ％ (22/45) in ALL.The MTHFR 677 T allele had an decreased risk in ALL compared with CC genetype (OR =0.4,95 ％ CI 0.21-0.83).The frequency of MTHFR 1298 AA,AC and CC genetypes were 57.8 ％,40.0 ％ and 2.2 ％ in controls and 18.8 ％,44.4 ％ and 6.8 ％ in ALL,respectively (x2 =11.23,P=0.23).The frequency of MTHFR 1298 C allele were 51.1％ (23/45) in controls and 42.2 ％ (19/45) in ALL.No significant association between the MTHFR 1298 polymorphism and the risk of ALL (OR =1.3,95 ％ CI 0.21-0.83).Conclusion MTHFR 677 polymorphism could significantly decrease the risk of developing childhood ALL,whereas MTHFR 1298 don' t significantly affect the risk of ALL.
