Up to now, advantages and disadvantages in the treatment of hypertensive middle_ and large_amount cerebral hemorrhage (HMLCH) by western medicine or traditional Chinese medicine,or by medical treatment or surgical treatment still exist. Mortality and disablement rate remain high. Western medicine combined with Chinese herbal medicine shows better effect in treating HMLCH, but the related research is preliminary. Therefore, thoughts of establishing comprehensive therapeutic protocols for HMLCH are presented as follows. Western medicine combined with Chinese herbal medicine is the fundamental therapeutic principle. Proper surgical operation should be employed promptly to clear away hemotoma and relieve the symptoms first according to the situation of the patient, hospital and the surgeon. Clearing heat and calming the liver, removing blood stasis and phlegm, relaxing the bowels and restoring consciousness are the fundamental therapeutic methods for HMLCH with yang_excess syndrome, and reinforcing Qi and activating blood circulation, removing phlegm and dredging channels, relaxing the bowels and restoring consciousness for yin_excess syndrome. Routine treatment and symptomatic treatment also should be taken into account.

OBJECTIVE: To explore the composition characteristics of traditional Chinese medicine (TCM) syndromes in patients with acute ischemic stroke of yin or yang syndrome by investigating the characteristics of TCM syndromes at different periods after onset. METHODS: One thousand two hundred and forty-six patients with acute ischemic stroke were admitted in twenty hospitals. According to the "diagnostic criteria of syndrome differentiation of stroke", the characteristics of syndromes in the patients were investigated at the periods of 1-3 days, 4-10 days and 11-30 days after they had ischemic stroke. General distribution of six basic syndromes was compared between the patients with yin syndrome and the patients with yang syndrome at the three periods. The six basic syndromes were wind syndrome, pathogenic fire syndrome, phlegm syndrome, blood stasis syndrome, qi deficiency syndrome, and syndrome of yin deficiency and yang hyperactivity. RESULTS: The percentages of wind, pathogenic fire, and phlegm syndromes in the patients were decreased at the period of 11-30 days as compared with the period of 1-3 days (87.1% vs 79.3%, 52.1% vs 38.7% and 67.1% vs 57.4% respectively, P<0.01). However, the percentages of the syndromes of blood stasis, qi deficiency, and yin deficiency and yang hyperactivity were similar at the three periods (P>0.05). There were no differences in the distribution of yin and yang syndromes among the three periods (P>0.05). The percentages of syndromes of wind, pathogenic fire, phlegm, and yin deficiency and yang hyperactivity were higher (P<0.01), and the percentages of syndromes of blood stasis and qi deficiency were lower (P<0.05, P<0.01) in patients with yang syndrome than in patients with yin syndrome. The complex of three syndromes was the most frequent composition pattern in the patients at the three periods. The percentages of complex syndromes of four or five syndromes were higher, and the percentages of single-syndromes and complex syndromes of two syndromes were lower in patients with yang syndrome than in patients with yin syndrome (P<0.05, P<0.01). The most frequent complex syndromes in patients with yin syndrome were complex syndrome of wind, phlegm, blood stasis and qi deficiency, and complex syndrome of wind, phlegm and qi deficiency; while the most frequent complex syndromes in patients with yang syndrome were complex syndrome of wind, pathogenic fire, phlegm and qi deficiency, and complex syndrome of wind, pathogenic fire and phlegm. CONCLUSION: The main discrimination between the yin and yang syndromes is that the yang syndrome is characterized by pathogenic fire. The syndromes of phlegm, qi deficiency, and blood stasis are not associated with the diagnosis of yin or yang syndrome.

0bjective To investigate the relationships between the peripheral lung cancer and pulmonary vessels or bronchi by 16-row muhislice computed tomography(MSCT)and analyze the related factors.Methods Fifty-four patients with peripheral lung cancer confirmed pathologically underwent contrast-erdaanced MSC TI Multiplanar reformation(MPR)and maximum intensity projection(MIP)in all patients were used to demonstrate the relationships between the peripheral lung cancer and pulmonary vessels,bronchi.The relationships were categorized five types:Type 1,erupted at the edge of nodule. Type 2,erupted at the center of nodule.Type 3,penetrated through the nodule.Type 4,contacting the nodule but stretched or encased.Type 5,contacting the nodule but smoothly compressed.The pathology type,stage,size,density and location of the peripheral lung cancer were recorded and the relationships with five types were evaluated by using Chi-square test and correlation analysis.Results (1)Tumor-bronchi relationship:type 1(33,61.1%)was more often seen in≥2.0 cm and solid lesions with stage Ⅱ-Ⅳ.while Type 2(14,25.9%)was often seen in<2.0 am and part-solid or non-solid lesions with stage Ⅰ.(2)Tumor-PA relationship:Type 1 was more often seen in≥2.0 am and solid lesions with stage Ⅱ-Ⅳ.while Type 2 was often seen in part-solid or non-solid lesions with stage Ⅰ.(3)Tumor-PV relationship:type 4 was the most common type(29,53.7%).Type 2(13,24.1%)was more often seen in part-solid or non-solid lesions.(4)Tumor-bronchi relationship and tumor-PA relationship had a positive correlation(r=0.5265,P<0.01).Conclusions MSCT can demonstrate the relations between the peripheral lung cancer and bronchi.PA and PV.It is useful for the differential diagnosis and prognosis evaluation of the lung csncer.

Over the past 30 years, Yarrowia lipolytica, Kluyveromyces, Pichia, Candida, Hansenula and other non-conventional yeasts have attracted wide attention because of their desirable phenotypes, such as rapid growth, capability of utilizing multiple substrates, and stress tolerance. A variety of synthetic biology tools are being developed for exploitation of their unique phenotypes, making them potential cell factories for the production of recombinant proteins and renewable bio-based chemicals. This review summarizes the gene editing tools and the metabolic engineering strategies recently developed for non-conventional yeasts. Moreover, the challenges and future perspectives for developing non-conventional yeasts into efficient cell factories for the production of useful products through metabolic engineering are discussed.
