Objective To investigate the effect of Urinarykallid for different ages patients with acute cerebral infarction cases.Methods Ninety-five cases with acute cerebral infarction were divided into high age group(n=48) and middle age group(n=47).Patients in the two groups were both given the Urinarykallid therapy combined with routine treatment.After 1 courses of treatment(3 weeks),American National Institutes of Health Stroke Scale(NIHSS) were performed before and after the treatment.The adverse reactions occurred in the process of scoring were compared.Results The total effective rate in the high age group was 83.33％,lower than the middle age group(89.36％),but the difference was not statistically significant(P=0.391).The NIHSS scores of patients in the two group after treatment were both significantly reduced compared with that in before treatment (high age grou:(9.81±2.37) vs.(6.79± 0.82),middle age group:(9.75 ± 2.46) vs.(3.04±0.58;P=0.004,P=0.001).Meanwhile,the NIHSS in the middle age group decrease significantly than the high age group(P=0.000).No obvious adverse reactions occurred in both two groups,the treatment was proved with safe and reliable.Conclusion Urinarykallid treatment is showed with better therapy effect on acute cerebral infarction patients with different age,and it is safety with improving patients NIHSS score level.Meanwhile,the better efficacy is showed in patients with lower age.

MicroRNAs(miRNAs) are endogenous non-coding RNAs,about 20 nucleotides in length.They play a pivotal role in the regulation of genes involved in diverse biology processes such as cell development,proliferation,differentiation and apoptosis by the translation repression or mRNA degradation.Recent evidence has suggested that miRNA alterations are involved in the initiation and progression of various human cancer including hepatocellular carcinoma(HCC),and miRNA-expression profiling of HCC has identified signatures associated with diagnosis,staging,progression and prognosis.As a novel molecular target,miRNAs holds great promise in diagnosis and biotherapy of HCC.

Circulating nucleic acids (CNAs) are extracellular nucleic acids found in cell-free serum,plasma and other body fluids from healthy subjects as well as in patients. The ability to detect and quantitate specific DNA and RNA sequences has opened up the possibility of diagnosis and monitoring of diseases,especially in the field of cancer. Furthermore,in some recent studies it has been suggested a kind of non-coding RNA-microRNA (miRNA),also exist in cell-free serum and plasma,highlighting the field of using CNAs to diagnose cancer. As a novel tumor marker,tumor-specific circulating miRNAs holds great promise in early diagnosis of cancer.

Addition of oxygen-vectors(n-dodecane,n-hexane,hydrogen peroxide) to fermentation medium was recognized as a method of enhancing oxygen transfer and promoting lycopene yield by Blakeslea trispora fermentation.Higher lycopene production was observed in shake flask containing 1%(v/v) n-hexane,n-dodecane and 150 L/100mL hydrogen peroxide as compared to shake flasks without oxygen-vectors.The result of assays indicated that when oxygen-vectors (n-dodecane,n-hexane,1%,v/v) and hydrogen peroxide(50 L/100mL) were added to the 0-day and 1-day old culture of Blakeslea trispora the production of lycopene were 25.32%,72.84% and 40.35% higher than those without oxygen-vectors addition respectively.The production of lycopene increased 114.83% when n-dodecane and surface active agents were used at the same time.

Lycopene—a kind of important active compound of caroteinoids, is greatly beneficial to human health with its diverse biological functions. With the elucidation of lycopene biosynthetic pathway and cloning genes of relative enzymes from microorganisms, it is possible to regulate lycopene biosynthesis via genetic engineering. The biosynthesis pathways of lycopene and gene cloning of lycopene biosynthetic enzymes in microorganisms were reviewed, and gene engineering strains documented in previous works including: E.coli and yeast constructed by genetic recombination, mold strains enhanced the ability of producing lycopene by gene manipulation were summarized. At last, compared with the present methods, the problems existed in the process of construction were pointed out.

Objective:To investigate the clinical value of indocyanine green(ICG) fluorescence imaging in complex laparoscopic cholecystectomy.Methods:The data of 96 patients with complicated gallbladder stones with cholecystitis and cholecystitis who underwent laparoscopic cholecystectomy(LC) from July 2018 to August 2020 in Hepatobiliary and Pancreatic Surgery of Huangshi Central Hospital of Edong Healthcare Group were retrospectively analyzed. Before operation, the patients were divided into experimental group( n=44) and control group( n=52) according to whether indocyanine green was injected intravenously. Seven hours before operation, the experimental group was injected with 2.5 mg indocyanine green, the experimental group underwent LC under guidance of ICG fluorescence imaging technology. The control group underwent conventional LC. The recognition rate of common bile duct and cystic duct, complete anatomy time of gallbladder triangle, operation time, intraoperative blood loss, bile duct injury and residual stone rat were compared. The measurement data obeying normal distribution was expressed by ( Mean± SD), and the t test was used comparison between groups, and the chi-square test or Fisher exact probability was used comparison between enumeration data. Results:The operation was successfully performed in both groups, In the control group, 1 case was converted to laparotomy, There was no perioperative death. Before the incision of the serosa of the triangle of the gallbladder, In the experimental group, the common bile duct recognition rate was 84.1%(37/44), the recognition rate of cystic duct was 72.7%(32/44). In the control group, the common bile duct recognition rate was 26.9%(14/52), the recognition rate of cystic duct was 28.8% (15/52). There were statistically significant differences in the recognition rate of common bile duct and cystic duct between the two groups ( P< 0.05). In experimental group, the time of complete dissection of gallbladder triangle, the operation time, the intraoperative blood loss were (30.2±8.6) min, (48.2±9.8) min, (16.3±5.2) mL, and (46.7±13.9) min, (65.2±15.4) min, (26.1±11.3) mL in the control group, there were statistically significant difference in the above indicators between experimental group and control group( P<0.05). There was no extrahepatic bile duct injury and residual stones in the experimental group. In the control group, there was 1 case of right posterior hepatic duct injury, 2 cases of common bile duct injury and 1 case of residual gallstone. There was no significant difference in extrahepatic bile duct injury and postoperative stone residual rate between the two groups ( χ2=3.532, P=0.081). Conclusion:ICG fluorescence navigation is helpful for early identification of common bile duct and cystic duct in laparoscopic complex cholecystectomy, which can avoid iatrogenic bile duct injury and has good clinical value.
