Objective To observe the effect of ligustrazine injection combined with chemotherapy on common immunological parameters in patients with advanced hepatocellular carcinoma.Methods Eighty cases diagnosed with advanced hepatocellular carcinoma from January 2013 to January 2015 in the hospital were randomly divided into observation group and control group, 40 patients in each group.The control group received only conventional treatment of chemotherapy and observation group received ligustrazine injection on the basis of control group.The levels of interleukin-1 (IL-1), IL-4 and transforming growth factor beta ( TGF-β) wwere compared based on the record between two groups pre-and post-treatment.Results There were no significant differences between two groups in IL-1,IL-4 and TGF-βlevels pre-treatment.After treatment, the IL-1, IL-4 and TGF-βlevels in observation group were lower than those in control group [(41.4 ±11.8)vs (76.0 ±12.2)ng/L,(118.5 ±39.9)vs(223.0 ±47.3)ng/L,(6.7 ±3.2)vs(11.7 ± 2.6)ng/mL, respectively, all P<0.05].Conclusion Ligustrazine injection combined with chemotherapy has an exact effect on improving the immunological parameters associated with advanced hepatocellular carcinoma without significantly increasing side effects, it is worthy of further research and application.

Objective:To investigate the effect of actin related protein 2/3 complex subunit 2 (ARPC2) gene silencing on the biological characteristics of papillary thyroid carcinoma (PTC) TPC-1 cells through lentivirus-mediated RNA interference.Methods:TPC-1 cells infected with nonsense short hairpin RNA (shRNA) sequence lentivirus (shCtrl) was used as the control group. TPC-1 cells infected with ARPC2 shRNA interference sequence lentivirus (shARPC2) was used as the experimental group, in which the expression of ARPC2 gene was specifically interfered. The effects of silencing the expression of ARPC2 gene on the proliferation of TPC-1 cells were detected by using methyl thiazolyl tetrazolium (MTT) assay, flow cytometry, Western blot and colony formation test. Flow cytometry and Western blot were conducted to detect the effect of silencing ARPC2 gene on TPC-1 cells apoptosis and related proteins.Results:shARPC2 could efficiently infect TPC-1 cells, and the expression efficiency of green fluorescent protein was over 85%. Compared with the control group, TPC-1 proliferation was inhibited in the experimental group. The ratio of S-phase cells in the experimental group was reduced compared with that in the control group [(14.79±0.21)% vs. (21.13±0.33)%, t = 27.77, P < 0.05]. The ratio of G 1 and G 2/M-phase cells in the experimental group was increased compared with that in the control group [G 1 phase: (67.57±0.08)% vs. (62.06±0.36)%, t=25.56, P < 0.05; G 2/M phase: (17.64±0.12)% vs. (16.91±0.17)%, t=6.154, P < 0.05]. Meanwhile, the expressions of cell cycle-related proteins CDK2, CyclinE and CyclinD were reduced in the experimental group. The number of clone formation in the experimental group was less than that in the control group, the difference was statistically significant [(10±2) vs. (161±6), t=9.011, P < 0.05]. In addition, the apoptotic ratio of cells in the experimental group was higher than that in the control group [(8.60±0.77)% vs. (4.08±0.40)%, t=9.011, P < 0.05]. Western blot showed that the expressions of anti-apoptotic factors p21 and bcl-2 were reduced in the experimental group, while the expression of pro-apoptotic factor bax was increased. Conclusion:The interference with the expression of ARPC2 regulated by shRNA can inhibit the proliferation, and promote the apoptosis of PTC TPC-1 cells, indicating that ARPC2 may be a possible biological new target for the treatment of PTC.

Background: Obesity is an independent risk factor for gastroesophageal reflux disease (GERD), but the mechanism remains unclear. There are few studies focusing on the effectiveness of standard dose proton pump inhibitor (PPI) in treating obese GERD patients. Aims: To investigate the effect of obesity on esophageal motility and acid reflux in GERD patients and the efficacy of standard dose PPI in treating obese GERD patients. Methods: Patients who were initially diagnosed as GERD and met the inclusion criteria from January 2017 to October 2021 at Anhui Provincial Hospital were included in this study. The results of esophageal high-resolution manometry and 24 h esophageal pH-impedance monitoring before PPI treatment in patients with normal body mass index (BMI) and obesity (BMI≥28.0 kg/m

Agarwood is a traditional and precious medicinal material and natural spice in China and other southeast Asian countries.As the head of all spices,agarwood has many pharmacological activities such as analgesia,antidiarrheal,anti-inflammatory and antibacterial effects. Due to its high price and scarce resources,there were just a few previous studies on it,mainly focusing on the chemical compositions of the agarwood essential oil and solvent extract mixture. The components of agarwood oils obtained by supercritical extraction and steam distillation were analyzed by using Gas Chromatography-Mass Spectrometer( GC-MS),and then the agarwood oils compositions and contents were compared between the traditional extraction method and the recently emerging supercritical extraction method. Antioxidant experiments of scavenging DPPH,ABTS,hydroxyl radical,total reducing power and MIC experiments of five kinds of tester strains such as staphylococcus aureus were combined to illustrate the differences between these two kinds of agarwood oils in terms of antioxidant and bacteriostatic activities. The results showed that the main components of agarwood oil were sesquiterpenoids( 68. 68%) in steam distillation extraction method,but sesquiterpenoids( 23. 78%) and chromones( 29. 42%) in supercritical extraction method. Fourteen common components included benzyl acetone,α-santalol,γ-eudesmol,agarospirol and guaiol etc. The antioxidant activity and inhibitory MIC of agarwood oils in supercritical extraction method were better than those in steam distillation method,and the inhibitory effect of agarwood oil on the growth of bacillus subtilis was found for the first time.
