The fermentation conditions of lipase production by Geotrichum candidum Y162 were optimized. Initially, the most suitable carbon olive oil, nitrogen source soybean flour and NH4Cl, salt BaCl2 and MgCl2 were selected according to single factorial experiments respectively. Based on the result, screening methodology Plackett-Burman design was used to evaluate the effects of twelve factors related to lipase production and three statistically significant factors olive oil, BaCl2 and NH4Cl were selected. The path of steepest ascent was used to approach the optimal region of lipase production subsequently. Then, the optimal combined concentration for maximum enzyme activity were further optimized by response surface methodology and determined as follows: olive oil 2.35%, BaCl2 0.36%,and NH4Cl 4.69%.The optimization of culture conditions of G.candidum Y162 led to a 2.25-fold increase in lipase production relative to initial result 14.16 U/ml, which indicate that single factor in combination with response surface methodology is an effective method for optimization of lipase production conditions by G.candidum Y162.

OBJECTIVEMedicinal properties are the basic attribute of traditional Chinese medicines (TCM), while the medicinal property theory is the core theoretical foundation of TCM formula combination. In this particle, authors studied the characteristics of pharmacological effects of property combination of traditional Chinese medicines distributing along meridians, with the aim to introduce the medicinal property combination regularity into the design and optimization process of compound TCMs, and bring the medicinal property theory into full play in guiding the formula combination.
METHODIn this paper, TCMs distributing along "the lung meridian" was taken for example. The medicinal property combinations of TCMs distributing along "the lung meridian" recorded in Pharmacopeia (2010) was collected and processed. Besides, Chinese journal full-text database (CNKI) was used to collect all of pharmacological study literatures concerning the above TCMs that have been published since 1980. The pharmacological information was also supplemented by reference to Science of Chinese Materia Medica and Clinical Science of Chinese Materia Medica.
RESULTTCMs distributing along the lung meridian with different properties and tastes showed significant differences in pharmacological effects. For example, mild-sweet-lung medicines could lower blood sugar levels, decrease anoxia and enhance immunity; Mild-bitter-lung medicines showed anti-bacterial, anti-hypertension, anti-oxidation effects; Hot-sweet-lung medicines showed antibechic and anti-bacterial effects. And Hot-bitter-lung medicines showed phlegm eliminating and anti-inflammatory effects. Meanwhile, TCMs distributing along the lung meridian had similar pharmacological characteristics, such as anti-bacterial and anti-inflammatory effects, which is consistent with lung's feature in susceptibility to exogenous pathogenic factors.
CONCLUSIONIn this study, authors discovered pharmacological characteristics of different TCMs distributing along the lung meridian, which links TCM theory with modern study achievements and lays a foundation for establishing a TCM property formula combination system.

Studies on the prescription combination regularity based on medicinal tastes focus on the internal relations between the structure and hierarchy of the prescription combination system. In this paper, with the systematic and scientific self-similarity theory as the core ideology, authors systematically interpreted the self-similarity theory of medicinal properties, defined the self-similarity of prescriptions with identical or similar medicinal properties, and built the systematic view of medicinal property theory based on the prescription combination based on the entity grammar system. As a result, the system was conducive to integrating traditional Chinese medicinal knowledge of syndromes, therapeutic principles, efficacies, medicinal properties and tastes and achieving the automatic design and optimization process from symptoms to prescriptions, and providing scientific and feasible methods and technical systems for the application of the medicinal property theory, with a guiding significance to the technology, methodology and theory of decoction pieces compatibility, component compatibility and compound medicine design.

Objective To investigate the effects of hypertension on left atrial myocardial properties by strain and strain rate(SR)imaging.Methods A total of 56 consecutive patients with hypertension were divided into 2 groups:33 with normal LVMI and 23 with left ventricular hypertrophy.These patients and 20 controls underwent transthoracic echocardiography,strain and SR imaging examination.Atrial strain and SR values of hypertensive patients were compared with those of controls.Results When compared with the controls,early diastolic SR(ESR)was significantly decreased in hypertensive patients(P<0.01-0.001),with time to peak late diastolic SR corrected for heart rate(TASRe)significantly increased in normal LVMI subgroup(P<0.05).Moreover,late diastolic SR(ASR)were significantly decreased(P<0.05)in hypertensive patients with left ventricular hypertrophy as compared with normal LVMI.Conclusions Enlargement of left atrium leads to increased reservoir function in hypertensive patients,which compensates for the deterioration of conduit function.The duration of atrial systole may be prolonged to meet the need of ventricular filling in consequence of lower left atrial booster pump function.Noninvasive quantification of left atrial function by SR imaging enables evaluation of left atrial dysfunction due to hypertension.
