Objective To explore the factors related to the prognosis and survival duration of primary liver cancer patients after hepatectomy.Methods The data of primary liver cancer patientswho were treated by surgical resection were analyzed retrospectively.Kaplain-Meier method was used to evaluate survival rates.Log-rank test and Cox regression analysis were used to screen out related clinical phathology factors.Results The median survival time was eighteen months.Univarivate analysis showed that liver function Child-Pugh classification,cirrhosis,tumor size,HBV infection,AFP,portal vein tumor thrombus significantly correlated with survival rates (P ＜ 0.05).Multivariate analysis showed that liver function Child-Pugh classification,tumor size,AFP and portal vein tumor thrombus were the independent prognostic factors of primary liver cancer (P ＜ 0.05).Conclusion Many factors are related to the prognosis of primary liver cancer after operation.Liver function Child-Pugh classification,tumor size,AFP and portal vein tumor thrombus affect prognostic independently.

Objective To explore the feasibility of thoracic sympathectomy under video mediastinoscopy (VM) for palmar hyperhidrosis. Methods Operations on 55 patients with palmar hyperhidrosis were performed under general anesthesia with double lumen endotracheal tube placement. The patients were maintained in the 30?～45? semi-sitting position, with abduction of both arms to 90?. The VM entered the thoracic cavity via the third intercostal space on the anterior axillary line. The T 2～T 4 sympathetic ganglions were resected by electrocautery. Results Hyperhidrosis disappeared postoperatively in all the cases. The temperature of patients' both hands increased by 1.5～3 ℃,with their both hands becoming dry and warm. The operation time was 20～40 min (mean, 30 min) and the hospital stay was 3～7 d (mean, 4 d). No severe complications occurred. Mild subcutaneous emphysema along with pneumothorax was found in 3 cases and compensatory hyperhidrosis in the trunk happened in 5 cases. Conclusions Thoracic sympathectomy under VM is less invasive and simpler than that under video-assisted thoracoscopic surgery (VATS) in the treatment of palmar hyperhidrosis, being a feasible alternative.

Vasculogenic mimicry (VM) can promote tumor growth, invasion, and metastasis. The formation of VM is regulated by various proteins including epithelial cell kinase, phosphoinositide-3 kinase, and hypoxia-inducible factor 1. Local microenvironment also plays an important role in regulating VM formation.

Hepatitis C virus (HCV) accounts for the majority of cases of transfusion acquired hepatitis and may cause chronic hepatitis, cirrhosis and hepatocellular carcinoma. Currently, there is no vaccine against HCV and treatment is expensive and not always effective.The adaptive host immune response in viral clearance of HCV infection was described and the recent progress in vaccine development of HCV, focusing on the fields of DNA vaccine candidates, recombinant viral vectored vaccine candidates and combined (prime-boost) vaccine candidates were summarized. Some challenges and limitations of developing a HCV vaccine were also analysed. In summary, a promising approach of developing an experimental HCV vaccine to induce extremely potent and broad T-cell responses based on prime-boost strategy was presented.

Objective To investigate the effect of nano-?-linolenic acid on the expression of cathepsin B(CB) in mice with viral myocarditis(VM).Methods Eighty male Balb/c mice were randomly divided into 4 groups:control group,myocarditis group,low-dose intervention group and high-dose intervention group,each group had 20 mice.Mice in control group were inoculated introperitoneally with eagle′s solution,every mouse in the last 3 groups was treated with 0.1 mL Coxsackie B3 virus(CVB3) intraperitoneally.Then,mice in low-dose intervention group and high-dose intervention group were treated with 60 mg?kg-1and 180 mg?kg-1 nano-?-linolenic acid solution for 7 days,respectively.Mice in control group and myocarditis group were treated with 9 g?L-1 saline for 7 days.All mice were killed on the 15th day,and the specimens of hearts and serum were conserved.Myocardial histopathology was determined with hematoxylin and eosin stain.The expression levels of myocardial CB mRNA were detected by reverse transcription polymerase chain reaction.Serum CB concentration was examined by enzyme-linked immunosorbent assay.Results The mortality rate was 0,45%,30% and 20% in control group,myocarditis group,low-dose intervention group and high-dose intervention group,respectively;the mortality rate was significantly lower in high-dose intervention group compared with myocarditis group(P0.05).The expression level of CB mRNA and serum CB concentration were markedly higher in myocarditis group than those in control group(Pa

Deproteinized calf blood injection is composed of small protein-free molecules extracted from fresh calf blood. The pre-vious studies showed that it can improve metabolic balance by increasing glucose and oxygen uptake to enhance energy metabolism. In recent years, due to the expanding clinical applications of deproteinized calf blood injection, new observation results and ideas contin-ued to emerge. However, the reports of adverse reactions and excessive applications were also gradually increased. In order to provide reference for the promotion of reasonable clinical application, the paper reviewed the latest development in the studies on the clinical application of deproteinized calf blood injection.

Whole mount in situ hybridization with BHC80 RNA probe showed that BHC80 was expressed in zebrafish central nervous system. Morpholino-modified antisense oligonucleotide was injected into zebrafish zygotes to knock down BHC80 expression. BHC80 knockdown resulted in striking decrease of erythrocytes and accumulation of erythrocytes at PBI. Further investigation of embryonic erythrocytes marker βe3 globin and hematopoiesis transcription factors gata1, c-myb and lmo2 by in situ hybridization showed that the erythroid progenitors marked with gata1 in BHC80 knockdown embryos were high proliferation and their differentiation were delayed, which led to decrease of erythrocytes and accumulation of erythrocytes at PBI. Both in situ hybridization and microangiography indicated that vasculature pattern of BHC80 knockdown embryos were almost normal.

Objective To explore the effects of adriamycin-loaded immuno-nanoparticles on multidrug resistance (MDR) of hepatoma cell line SMMC-7721/ADM. Methods The cytotoxicity of the adriamycin-loaded immuno-nanoparticles on the bepatoma cell line SMMC-7721/ADM in vitro and the tumor cell-binding ability of adriamycin-loaded immuno-nanoparticles were detected. Results The effect of the cytotoxicity of adriamycin-loaded immuno-nanoparticles on the hepatoma cell line SMMC-7721/ADM was significantly better than that of adriamycin-loaded nanoparticles. Adriamycin-loaded immuno-nanoparticles had the specific binding ability with the hepatoma cell line SMMC-7721/ADM. Conclusions Adriamycin-loaded immuno-nanoparticles can overcome the MDR of the tumor in vitro. The mechanism may be that immuno-nanoparticles could adhere to the tumor cell membrane, and the release of the loaded adriamycin creates a high local concentration in the extracellular medium. The increased concentration gradient improves the diffusion of adriamycin from the extracellular medium to the intracellular medium.

Objective: To make out the optimal drug treatment regimen through the participation of clinical pharmacists in the treatment of one case of child with renal abscess complicated with iron deficiency anemia.Methods: Clinical pharmacists participated in the design of treatment program for the child, including the choices of drugs, dosage and route, and the treatment of adverse reactions, in order to make out the individualized medication.Results: By selecting the sensitive antibiotics, the renal abscess caused by Escherichia coli was cured successfully.Conclusion: Clinical pharmacists participating in clinical consultation can further optimize the treatment plan, and play an active role in the treatment of infected patients.
