OBJECTIVESTo investigate the clinical effect of sequential therapeutic intervention Yupei Qisun [compensating for weakness by invigorating Kidney (Shen) and Spleen (Pi) in advance] in Chinese medicine (CM) and hysteroscopic endometrial mechanical stimulation on the treatment of infertile patients with repeated implantation failure (RIF); and to study the differences in patients' endometrial thickness and type on the day of embryo transfer, serum hormone levels on embryo transfer day and clinical pregnancy outcomes.

METHODSIn the clinical study, 168 frozen-thawed embryo transfer (FET) cycles for couples with RIF conforming to the research protocol were randomly divided into three groups: a CM group with 56 cycles (CM combined with FET), a hysteroscopy group with 55 cycles (hysteroscopic endometrial mechanical stimulation), and a control group with 57 cycles (conventional FET). Differences in endometrial thickness on the embryo transfer day, levels of serum estradiol (E2) and progesterone (P) on the embryo transfer day, the E2/P ratio on the embryo transfer day, biochemical and clinical pregnancy rates, implantation rate, abnormal pregnancy rate and other indices were compared among the three groups.

RESULTSEndometrial thickness, E2 and P levels, and the E2/P ratio on embryo transfer day and other factors had no significant differences among groups. The biochemical pregnancy, clinical pregnancy, and implantation rates of the CM and hysteroscopy groups were significantly higher than the control group (P<0.05), and there were no significant differences between these two groups. The abnormal pregnancy rate had no significant difference among the three groups.

CONCLUSIONSSequential therapy of Yupei Qisun could significantly improve the clinical outcomes of rif-fet cycles, being equivalent to hysteroscopic endometrial mechanical stimulation, and provided a reliable method to treat such infertile couples.

OBJECTIVEFunctional defects in NK cells have been proposed to be responsible for the impairment of anti-tumor immune responses. However, it remained unclear whether the function of NK cells were impaired in patients with hepatocellular carcinoma. To address this issue, we analyzed the frequency and function of peripheral NK cell subsets in hepatocellular carcinoma (HCC) patients.

METHODS35 HCC patients and 24 healthy controls (HC) were enrolled in the study. Peripheral NK frequency was analyzed using flow cytometry. In addition, the capacity of NK cells to produce IFN gamma and to lyse K562 cells was evaluated.

RESULTSIn contrast with the healthy controls, the frequency of peripheral NK cells in hepatocellular carcinoma patients was decreased (12.19%+/-10.85% vs 24.01%+/-8.78%, u = 4.01, probability value less than 0.01), while the frequency of CD56(bright)CD16(neg) NK cells was increased (0.62%+/-0.39% vs 0.48%+/-0.28%, u = 1.96, probability value less than 0.05), and the frequency of CD56(dim)CD16(pos) NK cells was significantly decreased (11.59%+/-7.49% vs 22.66%+/-8.84%, u = 3.92, probability value less than 0.01). In addition, peripheral NK cells from HCC patients exhibited decreased capacity to produce IFN gamma (effective cells 13.31%) and to lyse K562 cells (mixed ratio 30:1, 10:1, 1:1, effective cells 16.72%+/-7.33% vs 26.29%+/-12.36%, u = 2.52, P less than 0.05, 8.01%+/-4.40% vs 13.09%+/-5.03%, u = 3.32, probability value less than 0.05, 3.51%+/-2.82% vs 3.42%+/-1.64%, u = 1.56, probability value more than 0.05, respectively) as compared with healthy subjects.

CONCLUSIONAnti-tumor activity of NK cells in HCC patients was impaired.

BACKGROUNDIt remains a challenge to inhibit the local recurrence or distant metastasis of localized or locally advanced renal cell carcinoma (RCC) after surgical resection. We investigated the feasibility, safety and efficacy of immunotherapy using autologous tumor lysate (TL)-pulsed dendritic cells (DCs) and cytokine-induced killer (CIK) cells in patients with localized or locally advanced RCC.

METHODSFrom January 2001 to July 2009, we collected 137 patients that met the selection criteria and randomly divided them into three groups. After surgery, immunotherapy with TL-pulsed DCs-CIK cells (DC-CIK group) and interferon (IFN)-α (IFN-α group) was performed in 46 patients, respectively. The other 45 patients received no postoperative adjuvant therapy (the control group). The changes in the numbers of T lymphocyte subsets, including CD4(+)CD25(high) regulatory T cells (Treg), were determined before the operation and after immunotherapy. The overall survival was compared among the three groups.

RESULTSAn increase of the CD4(+)/CD8(+) ratio and a decrease of CD4(+)CD25(high) cells were observed after TL-pulsed DC-CIK cells or IFN-a immunotherapy. All patients tolerated the TL-pulsed DC-CIK cells immunotherapy very well, and side effects in the DC-CIK group were less than in the IFN-α group. The metastasis and recurrence rates were significantly decreased after TL-pulsed DC-CIK cells or IFN-α immunotherapy compared with the control group (P < 0.01). The Log-rank test showed that the overall survival rates were significantly higher in the DC-CIK group and IFN-α group than that in the control group (P < 0.01), but there was no difference between the DC-CIK group and IFN-α group (P > 0.05).

CONCLUSIONPostoperative immunotherapy with TL-pulsed DC-CIK cells may prevent recurrence/metastasis and increase the overall survival rate after surgery in localized or locally advanced RCC.

OBJECTIVETo evaluate the efficacy and safety of Magnesium isoglycyrrhizinate in treatment of chronic liver diseases.

METHODSIt is a randomized, double-blind, multi-doses, active drug controlled, multi-center study. 480 proper patients were randomly divided into group A (180 patients), group B (180 patients) or group C (120 patients). Patients in group A received magnesium isoglycyrrhizinate 100 mg once daily. Patients in group B received magnesium isoglycyrrhizinate 150 mg once daily. Patients in group C received compound glycyrrhizin 120 mg once daily. The treatment course was 4 weeks. Patients were followed up 2 weeks after the treatment. Patients visited once every 2 weeks. Clinical symptoms, ALT, AST were evaluated in all the patients before treatment, at week 2, at week 4 and at 2 weeks later after treatment. The other liver function test was done before treatment and at week 4.

RESULTS412 patients completed the study according to the protocol,152 in group A, 160 in group B and 100 in group C. ALT and AST level were significantly decreased in all groups at week 2 and week 4 (P < 0.05). The degree of ALT decrease is greater in group B than in group C at week 2 (P < 0.01). The degree of ALT decrease was not significant different among three groups at week 4 (P > 0.05). The rates of ALT improvement at week 4 in group A, B, C were 92.59%, 91.76%, 88.29%, respectively (P > 0.05). The rates of symptoms improvement at week 4 in group A, B, C were 90.41%, 89.86%, 86.46% and 72.22%, 73.53%, 68.47%, respectively (P > 0.05). No relapse were found in all three groups after treatment. The rate of adverse event in three groups was similar (P > 0.05).

CONCLUSIONMagnesium isoglycyrrhizinate is an effective and safe treatment for chronic liver diseases.

OBJECTIVETo investigate the effect of lamivudine, interferon alpha and oxymatrine treatment for surviving hepatic failure patients with hepatitis B.

METHODS200 hepatitis B patients, including 100 subacute or acute-on-chronic hepatic failure survivals (group A), and 100 chronic (group B, n=100) hepatic failure survivals, were enrolled in this study. Patients in group A received interferon alpha (n=35), lamivudine (n=33) , or combinational lamivudine and oxymatrine (n=32) therapy for six months; Patients in group B received lamivudine (n=49), or combinational lamivudine and oxymatrine (n=51) therapy for six months, respectively. After the treatment, all patients were followed-up for six months.

RESULTSAt the end of follow-up, all patients in group A survived, while in group B three patients (6.1%) receiving lamivudine, and four (7.8%, P>0.05) receiving combinational therapy died; more than 90% of all survivals had their HBV DNA loss. The HBeAg/anti-HBe seroconversion rate in patients of group A treated with interferon alpha (9/17, 52.9%) was higher than that in patients treated with combinational lamivudine and matrine (5/16, 31.3%, P<0.05), which was higher than that in the patients treated with lamivudine alone (1/17, 5.9%, P<0.01), and the Knodell histological activity index score in patients treated with lamivudine (7.2+/-0.8, P<0.05) was lower than that in patients treated with interferon alpha (8.2+/-1.3, P<0.05), and the best efficacy was found in receiving combinational therapy (6.9+/-0.7, P<0.01); Lamivudine or lamivudine in combination with matrine significantly inhibited the intrahepatic inflammatory activities, but had no effect on the existing fibrosis in group B patients.

CONCLUSIONLong term nucleotide analogues treatment may delay the progress of fibrosis in hepatitis B-induced hepatic failure survivals, and the administration of matrine in time may further enhance the anti-fibrotic effect of nucleotide analogues.

BACKGROUNDCoronary intervention therapy is the main treatment for uremic patients with coronary heart disease. The studies on whether dialysis reduces the efficacy of dual antiplatelet drugs are limited. The aim of this study was to examine the effect of dialysis on antiplatelet drugs in uremic patients with coronary heart disease.

METHODSThis study included 26 uremic patients who had undergone percutaneous coronary intervention in China-Japan Friendship Hospital from November 2015 to May 2017. We examined their thromboelastography results before and after hemodialysis. Self-paired t-tests were employed to analyze changes in the inhibition rate of platelet aggregation.

RESULTSThe mean inhibition rates of arachidonic acid-induced platelet aggregation before and after hemodialysis were 82.56 ± 2.79% and 86.42 ± 3.32%, respectively (t= -1.278, P= 0.213). The mean inhibition rates of adenosine diphosphate-induced platelet aggregation before and after hemodialysis were 67.87 ± 5.10% and 61.94 ± 5.90%, respectively (t = 1.425, P= 0.167). There was no significant difference in the inhibition rates of platelet aggregation before or after hemodialysis. These results also applied to patients with different sensitivity to aspirin and clopidogrel.

CONCLUSIONDialysis did not affect the antiplatelet effects of aspirin and clopidogrel in uremic patients with coronary heart disease.

Objective: To evaluate the short-and mid-term efficacy of pediatric kidney transplantation and the risk factors for kidney graft and recipient. Methods: The baseline data and postoperative complications of pediatric donors and recipients of 284 kidney transplants were retrospectively analyzed in the Department of Kidney Transplantation in the First Affiliated Hospital of Zhengzhou University from August 2010 to May 2021 and all subjects were followed up until December 31, 2021. According to the survival status of donors and recipients, they were divided into the graft-loss group and the graft-survival group, and the recipient death group and survival group, respectively. Univariate comparison between groups was performed by Log-rank test, and Cox proportional risk model was used to explore the independent risk factors for the graft and recipient survival. Results: Among the 284 children recipients, 184 cases (64.8%) were male and 100 cases(35.2%) were female, and 19 cases (6.7%) were living relative donor renal transplantation, 19 cases (6.7%) were preemptive transplantation, and 8 cases were secondary transplantation. The age of 284 recipients at the time of transplantation was 13.0 (9.0, 15.0) years, among whom 29 cases aged 0-6 years, 96 cases aged 7-11 years old, and 159 cases aged 12-18 years. The 1, 3, and 5 year survival rates were 92.3%, 88.9% and 84.8% for the kidney grafts, and were 97.1%, 95.6% and 94.4% for the recipients, respectively. Multivariate analysis showed postoperative acute rejection (HR=3.14, 95%CI 1.38-7.15, P=0.006) and perioperative vascular complications (HR=4.73, 95%CI 2.03-11.06, P<0.001) were independent risk factors for the survival of kidney graft. Postoperative infection (HR=14.23, 95%CI 3.45-58.72, P<0.001) was an independent risk factor for the postoperative mortality of recipients. Conclusions: Pediatric kidney transplantation shows a good short-and mid-term prognosis. Postoperative acute rejection and perioperative vascular complications are the risk factors for the survival of kidney graft, and postoperative infection is the risk factor affecting the survival of recipient.

OBJECTIVE: Psoriasis is a common chronic inflammatory skin disease that is prone to recurrence, and the proinflammatory factor, cysteine-rich protein 61 (Cyr61), is important in its pathophysiology. Long-term clinical practice has shown that Sancao Formula (SC), a Chinese herbal compound, is effective in the treatment of psoriasis, but the precise mechanism remains unknown. In this study, we investigate the mechanism by which SC extract alleviates imiquimod (IMQ)-induced psoriasis. METHODS: The expression of Cyr61 in psoriatic lesions and normal healthy skin was detected using immunohistochemical analysis to investigate the biological role of Cyr61 in models of psoriatic inflammation. A psoriatic mouse model was established by topical application of IMQ, and the effect of topical application of SC extract was evaluated using the psoriasis area and severity index (PASI) score, hematoxylin-eosin staining, and histopathological features of the skin. Next, a HaCaT cell inflammation model was established using interferon-γ (IFN-γ), and the effect of SC extract on the mRNA and protein levels of Cyr61 and intercellular cell adhesion molecule-1 (ICAM-1) was confirmed using Western blot and quantitative real-time polymerase chain reaction analyses. RESULTS: Immunohistochemical staining showed that the expression of Cyr61 in psoriatic lesions was higher than that in normal skin samples (78.26% vs 41.18%, P < 0.05), and the number of Cyr61-positive cells in psoriatic lesions was also significantly higher than in normal skin (18.66 ± 2.51 vs 4.33 ± 1.52, P < 0.05). Treatment in mice with IMQ-induced psoriasis showed that SC extract could significantly improve the inflammatory phenotype, PASI score (10.875 ± 0.744 vs 3.875 ± 0.582, P < 0.05), and pathological features compared with those in IMQ model group; SC treatment was also associated with decreased levels of Cyr61 and ICAM-1. In the IFN-γ-induced inflammatory cell model, the mRNA and protein levels of Cyr61 and ICAM-1 were upregulated, while the SC extract downregulated the levels of Cyr61 and ICAM-1. CONCLUSION The results provide a theoretical basis for the involvement of Cyr61 in the pathogenesis of psoriasis, and suggest that SC should be used to target Cyr61 for the prevention of psoriasis recurrence.

BACKGROUND: Albuvirtide is a once-weekly injectable human immunodeficiency virus (HIV)-1 fusion inhibitor. We present interim data for a phase 3 trial assessing the safety and efficacy of albuvirtide plus lopinavir-ritonavir in HIV-1-infected adults already treated with antiretroviral drugs. METHODS: We carried out a 48-week, randomized, controlled, open-label non-inferiority trial at 12 sites in China. Adults on the World Health Organization (WHO)-recommended first-line treatment for >6 months with a plasma viral load >1000 copies/mL were enrolled and randomly assigned (1:1) to receive albuvirtide (once weekly) plus ritonavir-boosted lopinavir (ABT group) or the WHO-recommended second-line treatment (NRTI group). The primary endpoint was the proportion of patients with a plasma viral load below 50 copies/mL at 48 weeks. Non-inferiority was prespecified with a margin of 12%. RESULTS: At the time of analysis, week 24 data were available for 83 and 92 patients, and week 48 data were available for 46 and 50 patients in the albuvirtide and NRTI groups, respectively. At 48 weeks, 80.4% of patients in the ABT group and 66.0% of those in the NRTI group had HIV-1 RNA levels below 50 copies/mL, meeting the criteria for non-inferiority. For the per-protocol population, the superiority of albuvirtide over NRTI was demonstrated. The frequency of grade 3 to 4 adverse events was similar in the two groups; the most common adverse events were diarrhea, upper respiratory tract infections, and grade 3 to 4 increases in triglyceride concentration. Renal function was significantly more impaired at 12 weeks in the patients of the NRTI group who received tenofovir disoproxil fumarate than in those of the ABT group. CONCLUSIONS: The TALENT study is the first phase 3 trial of an injectable long-acting HIV drug. This interim analysis indicates that once-weekly albuvirtide in combination with ritonavir-boosted lopinavir is well tolerated and non-inferior to the WHO-recommended second-line regimen in patients with first-line treatment failure.
