The subject of this study is to improve the ability of Ralstonia metallidurans CH34, a phenol-degrading strain with anti-heavy metal feature by immobilization.The optimal conditions for immobilizing bacterial cells were obtained with cross act experiment. The phenol-degrading efficiency of immobilized Ralstonia metallidurans CH34 was investigated. Results show that phenol-degrading efficiency of immobilized cells is obviously superior to that of the free cells; The ability of its resistance to heavy metal have been greatly improved; When additional carbon sources were added in the simulated waste water, the immobilized R. metallidurans CH34 were affected less than the free cells.

Objective To design a pressure detection and control system in the medical compartment for bio-agent casualty emergency evacuation and en route treatment during responses to biological warfare or terrorist attack.Methods An instrument and a pressure transmitter were used for detection,display and alarm of positive and negative pressures in the medical compartment,and pulse width modulation was involved in to regulate fan speed and then to control the pressure inthe compartment.Results The system proved its ability to evacuate bio-agent casualty and fulminating infectious patient with no pollution to the environment.Conclusion The system realizes on-line monitoring of the filter absorber in the medical compartment,enhances the efficiency and reliability of casualty care and thus gains high military benefits.

Objective To investigate the efficacy of rehabilitation in treatment of patients with hypertensive cerebral hemorrhage. Methods 64 patients with hypertensive intracerebral hemorrhage according to whether the implementation of the rehabilitation treatment of patients were randomly divided into two groups, the observation group and the control group,and each group(32 cases) was observed at two of the limb motor function,activities of daily living and quality of life scores. Results There were high blood pressure in patients with cerebral hemorrhage FuglMeyer score, Barthel index score, QQL quality of life score after 4 weeks after treatment, scores were significantiy improved by the test showed significant difference( all P ＜0. 05). Conclusion Active rehabilitation in patients with hypertensive intracerebral hemorrhage could improve the patients' limb motor function and daily life, improve quality of life of patients.

Plateau environment has a wide range of diurnal temperatures and thin air. The surgical shelter needs to resist the huge temperature shock and work in harsh environments, placing higher noise immunity requirements on the microenvironment temperature control system. The traditional microenvironment control of surgical treatment shelters mostly use instrument display and switch control, with a high failure rate and functional dispersion. We have designed a plateau microenvironment temperature control system with PLC as the control center and the touch screen as the Human Machine Interface so that real-time monitoring and control of temperature is achieved and the plateau temperature shock is resisted while the heater fuel ratio can be adjusted properly to adapt to plateau environment. This paper describes the control system hardware, software and algorithm design in detail.

Objective: The main objective of the present study is to develop the risk-adjusted capitation pay-ment standards to compensate health service providers. Methods:Descriptive statistical analysis was conducted to an-alyze the insured's enrollment and visit conditions, and the two-part model was conducted to obtain the appropriate compensation standard using data retrieved from information system of social health insurance for the period of 2014 to 2015 in Shenzhen City. Results:The estimated value of total expenditure per insured person per month is 6. 17 yuan. Age,sex,insurance level and with or without chronic disease or catastrophic disease were elicited as risk adjustors. The whole number insured people were divided into 52 groups by this four risk-adjustment factors whereby the rele-vant payment standards for each group was calculated. Conclusions:By adjusting capitation fee on the grounds of risk of disease and expected expense of medical services of the insured, the capitation payment standards can be calculat-ed virtually. This method will promote the process of capitation payment system reform and also lay a solid foundation for further research.

OBJECTIVE:To gain a clear idea about the situation of marking the period of validity on the wrapper and specifications of patent Chinese materia medica(PCMM) in China METHODS:To investigate the period of validity marking on wrapper and internal packing of 369 commonly-used PCMM in our hospital RESULTS:The PCMM with period of validity marking accounted for 65 9% of total PCMM(usually 1 5～3 years) and those without period of validity accounted for 34 1% CONCLUSION: The absence of period of validity marking is very common,we should pay attention to it

Objective To study the theraputic effect of cyclophosphamide,glucocorticoid combined with sildenafil on pulmonary hypertension in systemic lupus erythematosus(SLE?PAH) patients,and to analyze the prognosis adverse factors. Methods Forty?six cases patients with SLE?PAH from Tangshan Gongren Hospital from January 2009 to January 2015 were selected as research subjects. All patients were treated with prednisone, cyclophosphamide and sildenafil,and the course of treatment was 24 weeks. The treatment effect was observed, the systemic lupus erythematosus disease activity score(SLEDAI),6 minutes walk distance and heart function before and after the treatment were compared. The effective and uneffective patients'clinical and test information were compared,and the prognosis adverse factors were analyzed. Results After 24 weeks treatment,the total ef?fective rate was 78. 3%(36/46). Pulmonary artery systolic pressure(PASP) dropped from (59±16) mmHg be?fore treatment to (45±15) mmHg after treatment,there was significant statistical difference(t=-4. 539,P<0. 01). SLEDAI dropped from (6. 6±2. 3) points to (2. 4±0. 8) points,,there was significant statistical differ?ence(t =11. 680,P<0. 01). The 6 minutes walk distance rose form (402±96) minutes to (465±97) minutes, there was significant statistical difference( t=-3. 137,P<0. 01) . Cardiac function improved significantly,there was significant statistical difference( P<0. 01) . There were 10 cases uneffective and deterirated patients,with the age of (42±6) years,36 cases effective patients with the age of (33±4) years,the difference was statistically significant( t=-5. 423, P<0. 01 ) . Uneffective and deterirated patients' anti?RNP antibody positive rate was 90. 9%( 9/10 ) , significantly higher than the effective patients ( 52. 8%( 19/36 ) ,χ2 = 4. 552, P<0. 01 ) . Conclusion Cyclophosphamide, glucocorticoid combined with sildenafil has obvious effect on patients with SLE?PAH. PASP,heart function and 6 minutes walk distance are the important indicators of prognosis. Anti?RNP antibody and age are the adverse prognostic factors.

Objective To study the value of the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in gene diagnosis on spinal muscular atrophy (SMA).Methods PCR-RFLP method was used to detect the homozygous deletion of the exon 7 or exon 8 of SMN gene in 20 SMA patients of Type Ⅰ,Ⅱ,Ⅲ and 15 normal individuals.Results Homozygous deletion of exon 7 and exon 8 of the SMN gene were all identified 7/7 in SMA TypeⅠpatients, and 5/5 and 4/5 respectively in SMA Type Ⅱ patients, but only 1/8 of SMA Type Ⅲ patients, and no homozygous deletion was found in the normal controls.Conclusions PCR-RFLP might be recommended as an effective diagnosis for spinal muscular atrophy Type Ⅰand Ⅱ patients, whereas the method might not be as useful in Type Ⅲ as in Type Ⅰand Ⅱ for the gene diagnosis.
