Objective To investigate the effect of goal-directed fluid treatment (GDT) on prognosis during emergency operation for craniocerebral trauma patients.Methods Thirty craniocerebral trauma patients treated with emergency craniotomy from January 2015 to October 2015 were divided into control group (n =15) and GDT group (n =15),according to the random number table.In control group,the patients [ten males and five females,age of (40.3 ± 12.1) years and weighting (62.1 ± 9.1) kg] were given conventional fluid therapy based on the intraoperative mean arterial pressure,heart rate,central venous pressure,etc.In GDT group,the patients [eleven males and four females,age of (44.5 ± 9.6) years and weighting (64.0 ± 6.9) kg] received GDT based on the stroke volume variation (SVV) under Vigileo monitor.Serum levels of neuronspecific enolase (NSE) and S100-β were respectively detected by electrochemical luminescence and ELISA method before anesthesia induction (T1),1 h after dura incision(T2),immediately after surgery (T3),6 h after operation(T4),24 h after operation(T5) and 48 h after operation (T6).Intracranial pressure and cerebral perfusion pressure (CPP) were detected at all time points,and Glasgow Coma Score (GCS) at T1,T5 and T6.Postoperative infection,brain edema,hospital stay in ICU,total hospital stay and death rate were recorded.Results Compared with control group,levels of NSE in GDT group were decreased at T4,T5 and T6 and levels of S100-β in GDT group were decreased at T3,T4,T5 and T6 (all P ＜ 0.05).Intracranial pressure in GDT group was not significantly different from that in control group (P ＞ 0.05).GCS at T6 was higher in GDT group than that in control group (P ＜ 0.05).Length of ICU stay and length of total hospital stay in GDI group were (4.5 ± 2.1) d and (14.3 ± 3.6) d respectively,shorter than (6.3 ± 1.9) d and (18.3 ± 4.0) d in control group (P ＜ 0.05).None experienced infection,brain edema and death after operation.Conclusion Compared with conventional fluid therapy,GDT is beneficial to the prognosis of craniocerebral trauma patients undergoing emergency craniotomy without increasing intracranial pressure and brain edema,and GDT can reduce hospital stay.

Based on vector auto-regression (VAR) model, this paper takes advantage of Granger causality test, variance decomposition and impulse response analysis techniques to carry out a comprehensive study of the factors influencing the price of Chinese herbal, including herbal cultivation costs, acreage, natural disasters, the residents' needs and inflation. The study found that there is Granger causality relationship between inflation and herbal prices, cultivation costs and herbal prices. And in the total variance analysis of Chinese herbal and medicine price index, the largest contribution to it is from its own fluctuations, followed by the cultivation costs and inflation.

Traditional Chinese medicine market is a typical market with information asymmetry, which may lead to "lemons" problem. Third-Party Certification is efficient path to solve the problem of information asymmetry. For this reason geo-authentic and commodity classes certification seems to be very important. But as we know, information asymmetry happen in the stages of traditional Chinese patent medicines market. So a signaling transfer mechanism, which can deliver the quality signal, is badly needed in TCM market. This paper analysis and design of signaling transfer mechanism based on Third-Party Certification, which called quality prestige index of TCM enterprises (QPITCM). QPITCM can display quality information as a signal run through the TCM market.

Wound healing is a complex and highly regulated process to maintaining the skin barrier function. Wounds of diabetic patients are hard or even not healing. Non-healing diabetic foot ulcers can lead to lower-extremity amputations. Diabetic wound healing problem is the main complication that leads to high disability rate of diabetes and can threaten the lives in severe cases. The healing of skin wounds requires the synergy of multiple factors to restore the injured skin to its barrier function. The mechanisms that cause it difficult to heal diabetic wounds are complex, including oxidative stress, chronic inflammation, decreased neovascularization, peripheral neuropathy, and imbalance of extracellular matrix accumulation and remodeling. This review classifies mechanisms of diabetic wound healing and provides a reference for its further research.

To analyze the mortality risk of stroke in China by literature search.The mortality rate of stroke (age standardized) in China has declined in recent years.The mortality rate of stroke which increases with age is higher in rural areas than in urban areas,and is higher in men than in women in China.There are obvious regional differences and seasonal differences in the mortality of stroke in China.Different subtypes of stroke have different death characteristics.Low or high temperatures can increase the risk of mortality of stroke.With the change of epidemiological characteristics,the risk factors of mortality of stroke in China are also changing.Through the epidemiological study of stroke death,the mortality risk of stroke can be researched effectively,the epidemiological characteristics of stroke can be mastered,and the direction of prevention and treatment of stroke can be understood.Individualized and multi factor intervention for unhealthy lifestyle,unhealthy behavior and metabolic cardiovascular risk factors can promote the establishment of stroke prevention and control strategy in China.

Objective To study the effect of potassium chloride (KCl) before CPR on successful resuscitation of rats with ventricular fibrillation (VF).Methods Sprague-Dawley (SD) rats with VF induced by alternating electricity current were randomly (ramdam runmber) divided into KCl group and normal saline (NS) group.Rats of two groups were prepared with 0.8 mL/kg of 2.5％ KCl in KCI group and equivalent volume of NS in NS group instead before CPR.The resuscitation was considered to be failure if ROSC was absent for 10 min.The comparisons of time required for ROSC,the average attempt of defibrillation,the average joule used for defibrillation,ROSC rate and 72 h survival rate were carried out between the two groups.Results The length of time required for ROSC in the KCl group (n =10) was shorter than that in NS group (n=10) [(283.89±152.44) svs.(404.38±164.27) s] (t=1.369,P =0.196).The average attempt of defibrillation in KCl group were fewer compared to the NS group [(1.50 ± 0.75) times vs.(2.66 ± 0.57) times,(t =2.701,P =0.022)],the average joule used for defibrillation in KCl group were less compared to NS group [(3.75 ± 2.86) J vs.(8.33 ± 2.88) J,(t =2.78,P =0.019)].The ROSC rate in the KCl group was higher than that in NS group (P =0.011).The 72 h survival rate in KCl group was higher than that in NS group (P =0.001).Conclusions Increasing plasma potassium level before CPR could increase the ROSC rate and survival rate in rats with VF.
