The smoke of anti-infrared smoke agent in a self-made miniature smoke chamber was determined by using Forier transform infrared spectrometer. The smoke changing and settling regulation with time were obtained by measuring the IR spectra of smoke at different time dynamically. Through testing the smoke of different quantity of the same smoke agent, it was found that the relationship between the concentration of the main smoke products and the absorbance obeyed Lambert-Beer′s Law. Finally, the relationship between the smoke screening ability and reactant agent amounts was obtained by calculating the screening ability of different amounts of reactant agent in three “atmosphere windows”.

Objective To establish an HPLC method to simultaneously determine the contents of shikonin andβ,β'-dimethylacrylshikonin inZizhu Ointment.Methods The contents of shikonin andβ,β'-dimethylacrylshikonin inZizhu Ointment were determined by HPLC. The chromatographic conditions were Welch Materials XB-C18 Column (4.6 mm × 250 mm, 18.5μm), with mobile phase of acetonitrile-water-formic acid (75:25:0.05), detection wavelength of 516 nm, temperature of 30℃, flow rate of 1.0 mL/min and the load of 20μL.Results Shikonin showed a good linearity in the range of 0.025 6-0.256μg (r2=0.999 5), and the average recovery rate was 98.12% (RSD=1.92%).β,β'-dimethylacrylshikonin showed a good linearity in the range of 0.174 4-2.616μg (r2=0.999 2), and the average recovery rate was 100.46% (RSD=1.17%).Conclusion This method is simple and accurate, which can be used for the quality control and evaluation of Zizhu Ointment.

Through the doctor group, the questionnaire survey to understand what the doctor online habits situ-ation of network communication, doctors and patients, the effect of the real network environment for medical diag-nosis and treatment, news media under the network environment on the influence of the doctor and the doctor group about web development comprehensive view of the impact of the doctor-patient relationship.Points out that the current network environment brings to the doctor-patient relationship: the influence of the Internet become some doctors information update and the accumulated knowledge source, network has become an important platform inter-action some doctors and patients, doctors need to deal with an increasing number of network patients, the doctor-shave reactive shifts to the media negative reports.

BACKGROUND:Osteoporosis and its complications severely threaten the elder’s health. Simvastatin, widely accepted as a lipid-lowering drug, is reported to potentialy promote bone formation, but it is in debate when oraly administered, and there is no evidence to support whether this is due to the region difference.
OBJECTIVE:To investigate the effect of oraly administered simvastatin on bone mass and biomechanical properties of the femur and vertebrae in osteopenia rats induced by ovariectomy (OVX).
METHODS: Twenty-four 6-month-old female Sprague-Dawley rats were subjected to OVX+oraly administered saline vehicle (OVX group,n=8), OVX+oraly administered simvastatin (5 mg/kg/d; intervention group,n=8) or sham surgery (sham group,n=8). After 8 weeks of treatment, al rats were sacrificed and the level of procolagen type I N-terminal propeptide in blood serum was assessed by ELISA. Bone mineral density was determined in the L5 vertebra and left femur using dual-energy X-rays. Furthermore, the biomechanical properties of the L4 vertebra and right femur, including maximum load and elastic modulus, were detected by compression testing and three-point bending test, respectively.
RESULTS AND CONCLUSION: The serum level of procolagen type I N-terminal propeptide in the sham group was significantly lower than that in the other two groups. OVX rats showed significantly lower bone mineral density in both the L5 vertebra and left femur than sham rats (P < 0.05). Rats in the intervention group showed higher bone mineral density than those in the OVX group, with statisticaly significant difference in the L5 vertebra (P < 0.05), but insignificant difference in the femur. Maximum load and elastic modulus of the L4 vertebra in the OVX group were significantly lower than those in the sham and intervention group. Markedly lower elastic modulus of the femur was found in the OVX group than the sham and intervention groups. These findings demonstrate that simvastatin treatment can partialy prevent bone loss in OVX rats with more notable effect on the vertebrae than the femur, and for this model, the vertebra is superior to the femur used in biomechanical test.

Acute kidney injury ( AKI) is a clinical syndrome associated with increased morbidity and mortality, and early recognition is critical .In an attempt to engage laypeople and non-experts,the term kidney attack has been introduced to refer to acute kidney injury (AKI),and AKI with functional loss and tubular damage can be diagnosed both with functional criteria ( CRIAKI, creatinine increase AKI ) and damage criteria ( NCRIAKI, non-creatinine increase AKI ) according to the most recent ADQI consensus .This comprehensive definition of Acute Kidney Syndromes may be a major advancement in terms of early referral , prevention of progression and therapeutic strategies for AKI .

Objective To establish the quality standards of Zizhu ointment. Methods The TLC was applied to identify Radix arnebiae and borneol of Zizhu ointment, and the content of borneol was determined by gas chromatography. Results The TLC spots were clear, well-separated and easy to identify. The good linear range of borneol reference substance on calibration curve was 0.048 4-1.210 0 μg, and the recovery was 90%-110%, the relative standard deviation was less than 5%. Conclusion The method is simple and feasible, can be used as the quality control method of Zizhu ointment.

Objective To study the effect of psychological intervention combined with the analysis of Budesonide and Formoterol Fumarate Powder for Inhalation in treatment of chronic obstructive pulmonary disease. Methods 100 patients with chronic obstructive pulmonary disease treated in our hospital from February 2015 to March 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The control group was treated with the Budesonide and Formoterol Fumarate Powder for Inhalation treatment,the experimental group on the basis of psychological intervention on the mental status of patients and patients,strengthen communication and exchanges, increase confidence in the treatment and the treatment compliance of patients. Results After treatment, the SGRQ score of the experimental group was (57.33±16.81), and the score of the control group was (43.86±12.68) points, with statistical difference (P<0.05). The scores of depression and anxiety in the experimental group were significantly better than those in the control group,with statistical difference(P<0.05). Conclusion Budesonide and Formoterol Fumarate Powder for Inhalation combined with mental intervention in the treatment of chronic obstructive pulmonary disease can significantly improve the patients, improve the quality of life, help patients recover as soon as possible, has clinical significance.

Objective: This study aimed to analyze the high medical expenses of hospitalized medical insurance patients for the first ten systemic diseases.Methods: We investigated the medical expenses for the first ten systemic diseases among 10 900 hospitalized medical insurance patients of a hospital,calculated the average expenses and total payment for the treatment of each of the systemic diseases that involved 5% of the total patients,computed their percentage in the total expenses,and compared them with those of all the other hospitalized cases.Results: The medical cost of the 5% of the first 10 hospitalized systemic diseases accounted for 21%-29.9% of the total expenses of all the hospitalized patients,4.3-6.0 times that of the average expenses,and 30.8%-54.9% paid by the patients themselves.In addition,the hospital stay of these patients was 1.5-4.7 times that of the average.Conclusion: The high medical expenses involving 5% of the hospitalized patients with the first 10 systemic diseases amounted to a quarter of those paid by all the hospitalized patients.Effective measures have to be taken to keep high hospitalization expenses at a reasonable level.
