Objective To evaluate the efficacy and safety of lamivudine combined with thymosin α1 therapy for patients with chronic hepatitis B.Methods Sixty-eight eligible patients with chronic hepatitis B were enrolled in this multi-center randomized controlled rlinical trial.Patients were randomized into the trial group and the control group(n=34 for each).Patients in trial group received thymosin α1 for 6 months and lamivudine for 12 menths:patients in control group received lamivudine for 12 months only.The rates of serum HBV DNA clearance.HBeAg loss,HBeAg seroconversion,ALT normalization and the safety of thymosin α1 were observed at 3rd.6th,12th and 18th month during and after the treatment.Results At 12th month of the treatment,there were significant differences in the rates of serum HBV DNA clearance,HBeAg loss and ALT normalization between two groups(χ2=31.17,7.17 and 5.92,P＜0.05);at 6th month after the treatment.there were significant differences in the rates of sernm HBV DNA clearance and HBeAg loss between two groups(χ2=4.53 and 7.17,P＜0.05).HBV DNA was not detected in 2 patients during 6-month follow-up study and no sever side effect was observed throughout the study.Conclusion The conlbination of lamivudine and thymosin α1 is safe and has better effect than the monotherapy of lamivudine in patients with chronic hepatitis B.

AIM: To determine whether the eukaryotic initiation factor-4E (eIF-4E) inhibition facilitates the degradation of heparanase mRNA and alters heparanase protein expression in human colon adenocarcinoma cell line, LS-174T. METHODS: A 20-mer antisense s-oligodeoxynucleotide (asODN) targeted against the translation start site of eIF-4E mRNA were introduced into LS-174T cells by lipid-mediated DNA-transfection. eIF-4E protein and mRNA levels were detected by Western blot and RT-PCR, respectively. The mRNA levels of heparanase were determined by Northern blot. The alterations of heparanase expression were confirmed by Western blot analysis. RESULTS: The 20-mer asODN against eIF-4E specifically and significantly inhibited eIF-4E protein expression. Following eIF-4E inhibition, a significant reduction of heparanase mRNA was observed on Northern blot, and at the same time, heparanase protein expression significantly decreased as well. CONCLUSIONS: The results indicate that the inhibition of eIF-4E strongly reduces the stability of heparanase mRNA in colon adenocarcinoma cell line, LS-174T and resultes in an apparent reduction in the expression of heparanase protein.

ObjectiveTo investigate the potential of human amnion-derived mesenchymal stem cells to differentiate into insulin secreting cells in vitro.MethodsThe hAD-MSCs were isolated from human amnion by trypsin-collagenase digestion.The phenotype of the isolated cells was identified by flow cytometry and immunocytochemical staining.The 3rd generation cells were inoculated at density of 2.5 × 106 unit/ml or 5 × 105 unit/ml in 6 well plates or preset coverslip 24 well plates.Induced groups were treated in serum-free HG-DMEM with 10 mmol/L nicotinamide and N2 supplement.The cells in the non-induced groups were incubated in LG-DMEM supplemented with 10％ fetal bovine serum.At days 7,14 and 21 after induction,insulin and β2 microglobulin was determined by immunocytochemical stain,the content of insulin in the culture supernatant was assayed by radioimmunoassay,and insulin mRNA and PDX-1 mRNA were detected by reverse transcriptase-polymerase chain reaction.Results( 1 ) The hAD-MSCs highly expressed CD29,CD44,CD73,CD166,and vimentin.( 2 ) At 7,14,and 21 days,the percentages of insulin-positive cells in hAD-MSCs induced groups were 74.67％ ± 1.53％,75.00％:1.00％,and 74.33％ ±1.53％,respectively.Contents of insulin in the supematant of hAD-MSCs induced groups were ( 331.62 ± 1.76 ),( 330.50 ± 1.22 ),and ( 331.65 ± 0.48 ) μIU/ml,respectively,but non-induced groups were negative.(3) PDX-1 mRNA and PDX-1 protein were expressed before and after the induction of hADMSCs,but insulin mRNA was expressed only in the induced groups.( 4 ) Both hAD-MSCs induced groups and non-induced groups expressed β2 microglobulin ( all P ＞ 0.05 ).ConclusionThe hAD-MSCs have a potential of differentiating into ISCs and thus may become a new cell source of therapy for type 1 diabetes.

OBJECTIVETo investigate the development of xenografted primitive human germ cells by using fetal testicular tissues as donor tissues and an immunodeficient mouse as the recipient.

METHODSTesticular tissue fragments of a 26-week fetus were grafted under the back skin of a castrated immunodeficient mouse. Grafts were taken out after 135 days and processed for morphological and histological analyses.

RESULTSThe mass of grafts grew from about 1 mm in diameter and 5 mg in wet weight to about 3 mm and more than 20 mg 135 days after grafting. Histological observations showed a significant expansion of seminiferous tubules after grafting (80 +/- 25 microm in diameter) in comparison with seminiferous cords at the time of grafting (60 +/- 15 microm in diameter). The seminiferous cords developed into seminiferous tubules with the epithelial border and lumen. After 135 days of grafting, most of the dispersedly distributed primitive Sertoli cells and germ cells migrated to the basal part of seminiferous epithelium, located on the basement membrane and few of germ cells differentiated into spermatogonia.

CONCLUSIONHuman fetal testicular tissues could survive and continuously develop after being xenograft into castrated immunodeficient mice.

The American Association of Hip and Knee Surgeons, the American Academy of Orthopaedic Surgeons, and the American Society of Regional Anesthesia and Pain Medicine collaborated to develop an evidence-based study about the safe and effective use of Ketamine in total joint arthroplasty(TJA). Based on the systematic review and Meta-analysis of several studies, the following conclusions are drawn: Ketamine can effectively relieve the postoperative pain of patients; Ketamine can effectively reduce the occurrence of postoperative nausea and vomiting; Ketamine can reduce the use of postoperative opioids; intraoperative use of Ketamine does not increase the incidence of postoperative adverse reactions. The above conclusions are graded according to the strength of evidence support. This article interprets the guidelines to provide reference for addressing the effectiveness and safety of Ketamine use in TJA.

Objective:To investigate the feasibility and technical points of single posterior total spine resection for L 5 vertebrae tumors, evaluate the effectiveness and safety of the technique, and propose a comprehensive treatment model for L 5 tumors on this basis. Methods:A retrospective analysis was performed on the data of 13 patients with L 5 vertebrae tumor who were treated by total en bloc spondylectomy (TES) through single-stage posterior approach from January 2014 to September 2021, including 4 males and 9 females. The age range was 21-65 years, with an average age of 33.85±14.24 years. Imaging examination showed isolated tumors of L 5 vertebrae without other metastases. All patients were treated with a single posterior L 5 vertebrae tumor TES by adjusting the curvature of lumbar lordosis, and the lumbar nerve root was fully dissociated. The vertebra with tumor was removed entirely and lumbar stability reconstruction via a pedicle screw system. Various parameters, including operative time, blood loss, complications, preoperative and postoperative spine sagittal parameters, Japanese Orthopaedic Association scores (JOAs), tumor control and outcome, were listed and analyzed. Results:Preoperative pathological diagnosis of 13 patients was mainly primary bone tumor including giant cell tumor in 7 cases, and invasive hemangioma, epithelioid hemangioma, aneurysmal bone cyst, chordoma, plasma cell myeloma and bone metastasis of breast cancer in 1 case. The mean operative time was 333.23±99.48 min (range 175-480 min), and the mean intraoperative blood loss was 1 407.69±676.49 ml (range 300-2 800 ml). There were no serious perioperative complications during the perioperative period. The mean follow-up was 54.92±19.29 months (range 28-84 months). JOAs improved from 13.85±3.86 points before operation to 24.31±2.16 points at 6 months after operation, and the difference was statistically significant ( t=8.19, P<0.001). Postoperative delayed wound healing occurred in 2 case. 2 patients showed numbness of the left lower limb, and 1 patient had slightly reduced plantar flexion movement. Conclusion:Single posterior TES is a good surgical method for the treatment of isolated L 5 vertebrae tumors. Although this technique is difficult, it can reduce surgical wounds and postoperative complications and good functional and oncology prognosis can be achieved.
