35 patients with malignant lymphoma and 18 patients with multiple mycloma were investigated for expression of OKT10in pherpheral blood. A significant incresing of OKT 10 positive cells was found in most of patients (26/30, 16/18 cases respectively) with Non-Hodgekin's Lymphoma(NIIL) and Multiple myeloma(MM). The inereasing of OKT10 positive cells is related to the degrce of malignaency of patients with NIIL from low-grade to high-wade. No relationship between serum beta-2-microglobulin and OKT10 positive cells in patients with NIIL and MM was also found.

Objective To observe the changes in inflammatory mediators in plasma in respiratory distress syndrome(RDS) of neonates received lung protective ventilation treatment. Methods Sixty newborn infants,diagnosed as RDS of neonatal and needed ventilator support, were recruited from the intensive care unit from May 2003 to May 2006. Infant with RDS were randomly divided into two groups. Both had 30 newborn infants. The infants in the experimental groups received lung protective ventilation treatment tidal volume:5-8 ml/kg,positive end-expiratory pressure (PEEP):0.51~0.98 kPa, and the control groups received large tidal volume ventilation (tidal volume:10-15 ml/kg,PEEP:0-0.29 kPa). The contents of TNF-?, interleukin-6 in plasma were measured. Results After those two therapies, the contents of tumor necrosis factor-?(TNF-?), interleukin-6 in plasma decreased obviously, especially after receiving lung protective ventilation treatment. Conclusions There are statistical differences in the amount of inflammatory mediators released between the experimental group under lung protective ventilation treatment and the control group received large tidal volume ventilation,and better effects are seen in RDS infants under lung protective ventilation treatment .

Objective To analyze the influential factors of the prognosis of neonatal cholestasis. Methods The data on 106 newborns with neonatal cholestasis collected from January 1, 2009 to June 30, 2016 was collected and analyzed retrospectively. All cases were divided into cure group (99 patients) and improvement group (7 patients) according to the effect of oral ursodeoxycholic acid therapy and comprehensive medical treatment. There was no cure for invalid case. The clinical features, course of disease and curative effect were observed. The levels of total bilirubin (TB), direct bilirubin (DB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma glutamyl transpeptidase (γ-GT), total bile acid (TBA) were compared between two groups. The ratio of neonatal bacterial infection, cytomegalovirus (CMV) infection, sex, total intravenous nutrition (more than 7 d), perinatal hypoxia, premature birth, maternal complicated intrahepatic cholestasis of pregnancy (ICP) were compared between two groups. Multiple Logistic regression analysis was used to analyze the prognosis factors of neonatal cholestasis. Results The levels of serum ALT, AST, γ-GT, TB, DB and TBA in improvement group were significantly higher than those in cure group, the course of disease in improvement group was significantly longer than that in cure group, there were significant differences (P<0.05). A strong linear correlation was showed between course of disease and the levels of serum ALT, AST, TB, DB and TBA (tALT=13.050, tAST=14.696, tTB=12.771, tDB=13.776, tTBA=12.019, P < 0.05). Multiple Logistic regression analysis showed that the prognosis of neonatal cholestasis was associated with bacterial infection, CMV infection, total intravenous nutrition (more than 7 d) and premature ( OR=9.375, 7.909, 11.333, 11.333, P < 0.05). Conclusions The higher the level of serum TB, DB, TBA, ALT and AST, the longer the course of the disease. Bacterial infection, CMV infection, total venous nutrition( ≥ 7 d) and premature are the risk factors of the prognosis of neonatal cholestasis. Therefore, prevention of neonatal bacterial and CMV infection, reduction of the occurrence of preterm delivery and reduction of the total parenteral nutrition time are very important to improve the prognosis of neonatal cholestasis.

OBJECTIVE To investigate the transfer and diffusion of berberine hydrochloride(BBH), the main active component of Coptis and Phellodenticum in the system of carboxymethyl chitosan(CMCS)-sodium alginate(SA). METHODS CMCS and SA were stirred in a certain proportion, and D-gluconolactone(GDL) was added to form polyelectrolyte hydrogel. Rheometer was used to study the rheological properties of CMCS-SA hydrogel, including the elastic modulus G′ and the viscous modulus G′′. A BBH diffusion model for CMCS-SA hydrogel was designed, and the relevant rules of BBH permeation through CMCS-SA polyelectrolyte hydrogel were observed by UV-VIS. RESULTS The elastic modulus G′ of the hydrogel was measured when the ratio of CMCS to SA was 3∶1, 2∶1, 1∶1, 1∶2, and 1∶3. When the ratio of CMCS to SA was 1∶1, G′ was the highest, and the crosslinking strength of the hydrogel was the highest. The cumulative amount of BBH transfer was measured by the BBH transfer model, and the diffusion of BBH in CMCS-SA hydrogel was fitted as the skeleton dissolution by Peppas equation, indicating that BBH dissociation and the transfer efficiency increased as the amino group of CMCS decreased or the carboxyl group of SA increased. The elastic modulus G′ of CMCS-SA hydrogel increased with the increase of GDL content. The reason was that the binding force between CMCS and SA molecules gradually increased with the decrease of pH, and the crosslinking degree of the hydrogel was enhanced. When ratio of fixed CMCS to SA was 1∶1 and the GDL content was 0.15 g·mL−1, the formability of CMCS-SA hydrogel was good. In addition, when BBH was transferred in hydrogel with different concentrations of GDL, the transfer efficiency increased with the increase of GDL content. When BBH was delivered in different thickness hydrogel, the delivery efficiency of CMCS-SA hydrogel increased with the decrease of thickness. CONCLUSION The CMCS-SA hydrogel system, as a potential drug carrier for traditional Chinese medicine extracts such as BBH, is expected to serve as a gel carrier for transdermal drug delivery.

Gel materials have advantages such as comfortable touch, good air permeability, high viscoelasticity, etc., so they are widely used in modern transdermal drug delivery preparations such as patches, gel agents and film agents. With the innovative development of medical materials, many new gel materials with excellent functions have emerged, which has expanded the application scope of transdermal drug delivery preparations and optimized their properties. The classification, properties and application of gel materials in transdermal drug delivery system were reviewed, and the latest research progress was summarized, so as to provide reference for the innovative application of gel materials in transdermal drug delivery system.m.

Objective To investigate the protective effect of herba artemisiae scopariae extract on multidrug resistance protein 3(MDR3)gene mutation-induced neonatal parenteral nutrition-associated cholestasis(PNAC)and its possible mechanism.Methods ①Human primary hepatocytes were treated with cell culture in vitro,CRISPR/Cas9 lentivirus infection and MDR3 mutant gene lead-in.The levels of hepatic and biliary biochemical indexes[alanine transaminase(ALT),aspartate transaminase(AST),total bilirubin(TBil),direct bilirubin(DBil),indirect bilirubin(IBil),total bile acid(TBA)]in the supernatant of hepatocytes before and after 16,32,48 hours were compared to determine the time required for fatty acid induction of PNAC hepatocyte model with MDR3 gene mutation.② Human primary hepatocytes were divided into blank control group,MDR3 gene wild type group,MDR3 gene mutation group,and herba artemisiae scopariae extract intervention group according to random number table method.The blank control group was treated with culture medium only,the MDR3 gene wild type group was infected with lentivirus and mixed with wild type MDR3 gene and culture medium,the MDR3 gene mutation group was infected with lentivirus and cultured in culture medium with the mutant genes lead-in of LV-MDR3KI(c.485T>A,c.2793insA,c.1031G>A,c.3347G>A)mutation,while the MDR3 mutant gene was lead-in by lentivirus infection and cultured in culture medium,and then pretreated with 100 g/L herba artemisiae scopariae extract in the herba artemisiae scopariae extract intervention group,then the four groups of hepatocytes were induced with 1%fat emulsion,and the treatment time was the time needed to construct the PNAC hepatocytes model with MDR3 gene mutation.The levels of ALT,AST,TBil,DBil,IBil and TBA in the supernatant of hepatocytes were measured by enzyme-linked immunosorbent assay(ELISA).The mRNA expression abundance of adenosine triphosphate binding cassette proteins(ABCB4,ABCB11,ABCC2,ABCC3,ABCC4)encoding MDR3,bile salt export pump(BSEP),multidrug resistance associated protein(MRP)2-4,and tumor necrosis factor-α(TNF-α)genes were detected by real-time fluorescence quantitative polymerase chain reaction(RT-qPCR).Results Compared to the blank control group and MDR3 gene wild type group,there was no significant difference in the levels of ALT,AST,TBil,DBil,IBil,TBA in the supernatant of MDR3 gene mutant group before and 16 hours after induction with 1%fat emulsion,however after treated with 1%fat emulsion for 32 hours and 48 hours,the levels of ALT,AST,TBil,DBil,IBil,TBA in the supernatant of MDR3 mutant hepatocytes were significantly increased(P<0.05),consequently the time required for fatty acid induction of PNAC hepatocyte model was 32 hours.At 32 hours after treatment with fat emulsion,the levels of ALT,AST,TBil,DBil,TBA in the supernatant of hepatocytes in the herba artemisiae scopariae extract intervention group were significantly decreased[ALT(ng/L):148.3±2.3 vs.164.9±7.0,AST(ng/L):2767.4±78.8 vs.3239.4±107.1,TBil(μmol/L):7.6±0.2 vs.13.6±0.3,DBil(μmol/L):1.8±0.1 vs.5.7±0.2,TBA(μmol/L):3.4±0.2 vs.6.7±0.1,all P<0.05].The ABCB4,ABCC2,ABCC3,ABCC4 mRNA expression of MDR3,MRP2,MRP3,MRP4 in the blank control group,MDR3 wild type group,MDR3 gene mutation group and the herba artemisiae scopariae extract intervention group had no significant difference.The expression of TNF gene mRNA was highly expressed in MDR3 gene mutation group(2-??Ct:1.258±0.200 vs.1.001±0.052),and was low expressed in the herba artemisiae scopariae extract intervention group(2-??Ct:0.387±0.247 vs.1.258±0.200),and there was a significant difference between the two groups(both P<0.05).Compared to the MDR3 gene mutation group,the ABCB11 gene encoding BSEP mRNA expression in the herba artemisiae scopariae extract intervention group was significantly increased(2-??Ct:2.955±0.479 vs.1.333±0.529,P<0.05).Conclusion The herba artemisiae scopariae extract has a protective effect on PNAC induced by MDR3 gene mutation,which may be related to antagonizing inflammatory reaction,decreasing the expression of TNF mRNA and improving the expression of ABCB11 gene encoding BSEP.
