The invention relates to a treatment method of wastewater produced by cephalo synthetic drug manufacturing, which mainly comprises three parts, namely, aerobe catalytic oxidation, anoxia hydrolytic acidification and a membrane biological reactor; firstly, organic matters having better biodegradability in the wastewater are removed in a biological contact oxidation pond, then biological hydrolytic acidification is carried out in an anoxic pond, and then the wastewater flows into the membrane biological reactor to carry out final aerobic Bioremediation; the wastewater after the treatment passes through an ultrafiltration membrane in the membrane biological reactor and is pumped out by a pump and then discharged to an effluent pipe after reaching standards or recycled to the production technology; the membrane biological reactor consists of an aeration zone and a membrane filtering zone, wherein, the aeration zone carries out aeration by adopting a disc-shaped millipore aeration head, the ultrafiltration membrane is positioned in the membrane filtering zone, the organic matters in the wastewater after being treated with aerobe contact oxidation and anoxia hydrolytic acidification are basically biodegraded, the wastewater is pumped out through the ultrafiltration membrane, and microbes in the reactor are blocked in the reactor. The method has the advantages of simple technique, good effect of treating wastewater, small occupation area, and low treatment cost, and is especially suitable for the wastewater produced by the cephalo synthetic drug manufacturing.

A novel method of treating and preventing diseases is provided. In particular, compositions and methods of blocking diseases associated with aberrant levels of nitric oxide and facilitated by a serine proteolytic (SP) activity are disclosed, which consist of administering to a subject a therapeutically effective amount of a compound having a serine protease inhibitory activity. Among effective compounds are alpha1-antitrypsin and synthetic drugs mimicking some or all of the actions of alpha1-antitrypsin.

The invention discloses a method for directly oxidizing a benzyl-position C-H bond into ketone, wherein aryl ethyl compounds are catalyzed and oxidized by nitrite ester; a synergistic catalytic system of free radical initiator and nitrite ester is adopted, and a catalytic system of non-metallic catalyst and oxygen is adopted, the oxidization of the C-H bond of a free radical-activated aryl side chain is simple in operation; after completing the reaction, petroleum ether / ethyl acetate at a volume ratio of (50-1):1 is used as an eluent; column chromatography separation is performed to obtain a target product. The catalytic system in the invention uses oxygen as an oxygen source and has high atomic economy; the invention is a non-metallic catalytic system and provides a novel method for avoid metal residues in synthetic drugs; for diethyl aromatic hydrocarbon, the method provided by the invention can be adopted to selectively oxidize diethyl aromatic hydrocarbon into monoketone and diketone; the method of the invention can be adopted to efficiently synthesize tranquillizer lenperone, so that a novel method for synthesizing lenperone is provided.

This invention is drawn to compounds which are more easily metabolized by the metabolic drug detoxification systems. Particularly, warfarin analogs which have been designed to include esters within the structure of the compounds are taught. The invention teaches methods of reducing the toxicity of drugs comprising the introduction of ester groups into drugs during the synthesis of the drug. This invention is also drawn to methods of treating coagulation disorders comprising the administration of compounds which have been designed to be metabolized by serum or intracellular hydrolases and esterases. Pharmaceutical compositions of the ester containing warfarin, analogs are also taught.

The invention discloses a soil bactericide pesticide composite. The active ingredients of the pesticide composite comprise the following substances in percentage by weight: 5-30% of carbendazim, 5-20% of hymexazol, 5-20% of garlic oil and the balance of additive and filler. Through the combination of the carbendazim, the hymexazol and the garlic oil, the bactericidal effect of the soil bactericide pesticide composite is improved, the efficiency is increased, the drug resistance is delayed, the dosage of chemical synthetic drugs is reduced, and the efficiency is significantly increased because the garlic oil has high bactericidal power and strong fumigating and sterilizing function on soil. By adopting the pesticide composite capable of preventing and curing wilt of vegetables such as cucumber, the preventing and curing effect of wilt can be improved, the drug resistance of pathogenic bacteria can be delayed, and the preventing and curing cost can be reduced.

Disclosed is a method for producing exosomes having effects of skin regeneration and wound healing, comprising the steps of: providing ultrasonic stimulation directly or indirectly to cells; culturinga mixture of the cells and a medium for a predetermined amount of time; and separating exosomes from the mixture, wherein direct provision of stimulation is the application of ultrasonic stimulationto a medium comprising cells, and indirect provision of stimulation is the application of ultrasonic stimulation to a medium that does not comprise cells and then mixing the medium with the cells. Theexosome production method enables exosomes, having effects of skin regeneration and wound healing, to be obtained in a high yield and short amount of time by means of a simple process called sonication from stem cells, which are difficult to be handled, and also from somatic cells, which can be easily obtained and maintained. The exosomes obtained thereby also have a high amount and number of various included factors, the exosomes and compositions comprising same have increased various factors, which can induce skin regeneration and wound healing, and the exosomes have a phospholipid-based membrane structure so as to facilitate skin penetration and allow high efficiency of substance delivery, thereby enabling skin regeneration and wound healing to be effectively induced, and are safe andhave no side effects caused by the use of synthetic drugs.

The invention relates to a manufacturing method of a bamboo fence. The manufacturing method includes the following steps that (a) raw bamboos are subject to straightening cutting to obtain bamboo wood; (b) drying is carried out at the temperature ranging from 180 DEG C to 250 DEG C for 2 h to 3 h, and mould proof and insect prevention liquid is sprayed; cooling is carried out to 150 DEG C to 180 DEG C for 6 h to 10 h; and then mould proof and insect prevention liquid is sprayed, and cooling is carried out to 50 DEG C to 150 DEG C for 3 h to 6 h; (c) the fence is manufactured; (d) heat treatment is carried out for 3 h to 5 h under the conditions that the temperature is 120 DEG C to 200 DEG C and the pressure is 0.2 MPa; (e) water spray cooling is carried out; and (f) drying is carried out at 45 DEG C to 60 DEG C until the water content is 10% to 18%. According to the manufacturing method, the special mould proof and insect prevention liquid is adopted, and therefore the mould proof and insect prevention effect of the bamboo fence can be at least two years; and the mould proof and insect prevention liquid does not contain illegal synthetic drugs, and therefore bad effects on the environment and biology can be avoided. According to the manufacturing method, after bamboo wood heat treatment, nutrient substances in the bamboos are dissolved, and fungi inactivation is achieved. The color of the bamboos is changed from natural green to carbon black, and the colors of the bamboos with different ages and at different parts can trend to be the same.
