Succinic acid is widely used in the field of chemistry and food proces s. Compared to the traditional chemical synthesis, succinic acid production by fermentation has some benefits. The new process with competitive cost uses rene wable agricultural resources including green house gas CO 2 instead of fossil f uels and reduces pollution from chemical synthesis. In this article, research progr e ss in production of succinic acid by fermentation such as microorganisms, metabo lic pathways and its regulation, fermentation and isolation are briefly reviewed .

ObjectiveTo compare the effects of normal saline (NS), 10% hydroxyethyl starch (HES) and hypertonic-hyperoncotic solution (HHS,7.5% NaCl/10% HES) on regional cerebral blood flow (rCBF), brain edema and blood-brain barrier (BBB) in a rat model of traumatic head injury (THI) complicate with hemorrhagic shock. Methods60 SD rats were randomized into 5 groups: sham group (n=12), model group (n=12), NS group (n=12), HES group (n=12) and HHS group (n=12). rCBF and mean arterial pressure (MAP) were determined before and after THI, hemorrhagic shock and resuscitation. Cerebral water content and Evans Blue (EB) content were assessed 3 h after resuscitation.ResultsMAP and rCBF were restored to baseline values immediately after resuscitation in all resuscitated group and began to decrease 15 min, 30 min or 45 min later, respectively(P<0.05). 3 h after resuscitation, the brain water content was higher in NS group than those in sham or HHS group(P<0.05). EB contents of injured hemispheres were higher in model and NS group than those in HES or HHS group(P<0.05). ConclusionSmall-volume resuscitation with HHS can restore MAP and rCBF, decrease brain edema and improve BBB in a rat model of THI complicate with hemorrhagic shock.

Methods　According to the requirements of the Final Evaluation Plan of the National Plan for the Prevention and Control of Hydatid Disease and Other Major Parasitic Diseases (2016-2020), a retrospective survey method was adopted to collect relevant data on the implementation and safeguard measures of the prevention and control of major parasitic diseases, and population infection status in Hubei Province in 2016-2019. Results From 2016 to 2019, We carried out 2 920 992 person times of publicity and education, 209 times of prevention and control technology training, 7 680 person times of business training, with an average of 52 sessions and 1 920 person times per year. We have allocated 3.445 2 million yuan for the prevention and control of parasitic diseases, including 1.722 2 million Yuan froom provincial government, to achieved full coverage of safe drinking water in rural areas under the current national standards, and 7.687 9 million harmless toilets have been built in rural areas. From 2016 to 2019, we carried out 39 658 person times of monitoring and disease investigation, the infection rate of human liver fluke was 0, and the infection rate of soil transmitted nematode was 0.42%. While the annual infection rates varied, there was no statistically significant difference in infection rate between years (χ2＝2.276, P>0.05), but there were statistically significant differences in the infection rates between various soil nematodes (χ2=112.807, P<0.01). From 2016 to 2019, a total of 5 393 people were detected at 17 monitoring points, with the serum positive rate of 3.93% for paragonimiasis, there was a statistically significant difference in serological positive rate between years (χ2=146.011, P<0.01); a total of 738 stream crabs were collected, and the infection rate of intermediate host was 16.26%, wtih a statistically significant difference in the infection rate of stream crabs between years (χ2=49.731, P<0.01). Conclusions　From 2016 to 2019, we adhered to the prevention and control strategy of "prevention first, prevention and control combined", implemented comprehensively various prevention and control measures, and achieved remarkable results in Hubei Province. The key parasitic diseases have been in a low epidemic situation, meeting the requirements of the prevention and control objectives. But the transmission risk still exists, the next step is to continue to strengthen security and monitoring and consolidate the achievements of prevention and control.

Objective To study the changes and management of systemic and pulmonary hemodynamics during anhepatic period in patients undergoing orthotopic liver transplantation without veno-venous bypass.Methods Sixty-eight patients with end-stage liver disease undergoing orthotopic liver transplantation were enrolled in this research. Monitoring and recoding CVP, MAP, CI, HR, MPAP, PAWP PVR, SVR at different time points: preincision, before anhepatic, 5, 30 min of anhepatic, 5, 30, 60 min of neohepatic,ending of operation, 12 h and 24 h after operation. All the patients were divided into three groups according CVP during anhepatic period: group A(CVP <4 mmHg) ,group B(4 mm Hg≤CVP≤6 mmHg) ,group C (CVP>6 mmHg). Besides, calculating the concentration of dopamine, norepinephrine ,epinephrine and the volume of urine during of operation. Results There were different changes during different operation periods. During anhepatic period, HR, PVR and SVR increased, while CVP, CI, MAP, PAP, PAWP decreased(P<0.05). At early neohepatic period, HR decreased and CVP,PAWP, MPAP,CI,PVR SVR increased ,At the beginning of neohepatic period, MAP dacreased or increased quickly, and became steadily after 5 min. Among the three groups, the changes of hemodynamics in group B was slightest,and the concentration of dopamine, norepinephrine and epinephrine was smallest (P< 0.05 ). Conclusions The systemic and pulmonary emodynamics fluctuated sharply during anhepatic and early neohepatic period. It is important and useful to manage CVP 4 -6 mmHg, MABP ≥ 60 mmHg by infusing liquid and vasoconstrictors,such as dopamine, norepinephrine or epinephrine during anhepatic period.

Based on the character of the molecular structure, the prodrugs of phosphates and phosphonates were divided into two categories. The first is the drug which contained the phosphate group, introducing protected groups to increase lipophilicity and improve bioavailability. The other one is the drug which had no phosphate group, introducing the phosphate group into molecules to enhance the solubility, regulate the distribution coefficient and enhance the drug-like property. This review focuses on the application of phosphates and phosphonates in drug research and development based on improvement of physico-chemical property, drug safety and the pharmacokinetics.
