ObjectiveTo investigate the immunological characteristics of the patients with aplastic anemia (AA) and elevated hemogram parameters treated with Yiqi Yangxue prescription combined with Western medicine and the predictive effects of immunological indexes on elevated hemogram parameters, thus providing a reference for the prediction of the treatment efficacy and the adjustment of the treatment regimen. MethodA retrospective study was conducted, involving 77 AA patients treated with Yiqi Yangxue prescription combined with Western medicine for 6 months in 19 medical institutions including Xiyuan Hospital, China Academy of Chinese Medical Sciences from September 2018 to March 2021. The patients were assigned into two groups according to the elevations in hemogram parameters [including hemoglobin (HGB), white blood cell count (WBC), platelet (PLT), and absolute neutrophil count (ANC)] after 6 months of treatment. One group had the elevation <50%, and the other group had the elevation ≥50% compared with the baseline. The clinical and immunological characteristics were compared between the two groups. Result① Compared with the group with HGB elevation<50%, the group with HGB elevation≥50% showed elevated level of CD3+ human leukocyte antigen-DR (HLA-DR)+ and increased proportion of patients with T-helper cell type 2 (Th2)<5%, CD8+≥50%, and CD3+HLA-DR+≥9% before treatment (P<0.05, P<0.01). The multivariate Logistic regression analysis showed that CD8+≥50% before treatment was the independent influencing factor for HGB elevation ≥50% [odds ratio (OR)=12.000, 95% confidence interval (CI) 2.218, 64.928, P<0.01]. ② Compared with the group with WBC elevation<50%, the group with WBC elevation≥50% showed increased proportion of patients with CD3+HLA-DR+<6% and T-box transcription factor (T-bet)≥200% before treatment (P<0.05). The multivariate Logistic regression analysis showed that CD3+HLA-DR+<6% (OR=2.998, 95%CI 1.036, 8.680, P<0.05) and T-bet≥200% (OR=3.634, 95%CI 1.076, 12.273, P<0.05) before treatment were independent influencing factors for WBC elevation≥50%. ③ Compared with the group with PLT elevation<50%, the group with PLT elevation≥50% presented lowered Th1 and CD3+HLA-DR+ levels and increased proportion of patients with Th1<12%, CD4+≥6%, and CD3+HLA-DR+<5% before treatment (P<0.05, P<0.01). The multivariate Logistic regression analysis showed that CD3+HLA-DR+<5% before treatment was the independent influencing factor for PLT elevation≥50% (OR=16.190, 95%CI of 3.430 to 76.434, P<0.01). ④ Compared with the group with ANC elevation<50%, the group with ANC elevation≥50% showed no significant changes in the hemogram parameters before treatment. ConclusionAs for the AA patients with rapid elevation in HGB, Yiqi Yangxue prescription combined with Western medicine demonstrate significant effects in the patients with Th2<5% and CD3+HLA-DR+≥9%, especially those with CD8+≥50%. As for the AA patients with rapid elevation in WBC, the therapy was particularly effective in the patients with CD3+HLA-DR+<6% and T-bet≥200%. As for the AA patients with rapid growth in PLT, the therapy was particularly effective in the patients with Th1<12% and CD4+≥6%, especially those with CD3+HLA-DR+<5%.

ObjectiveTo explore the predictive factors for the efficacy of Yiqi Yangxue prescription combined with western medicine in treating aplastic anemia (AA) in non-elderly adults, so as to provide a reference for predicting the prognosis of this therapy. MethodA retrospective study was conducted with the clinical data of non-elderly adult AA patients who visited 19 hospitals including Xiyuan Hospital of the China Academy of Chinese Medical Sciences from September 2018 to March 2021 and were treated with Yiqi Yangxue Prescription combined with western medicine. According to the efficacy evaluation results at the 6th month of treatment, the patients were assigned into effective and ineffective groups. The two groups were compared in terms of the gender, age, disease classification [non-severe aplastic anemia (NSAA)/severe aplastic anemia (SAA)], course of disease, family history, complications, history of drug allergy, baseline blood routine examination [hemoglobin (HGB), white blood cell (WBC), neutrophil (ANC), platelet (PLT), and reticulocyte (Ret)], T lymphocyte subsets, degree of proliferation of nucleated cells in bone marrow, and expression of T-bet and GATA-3. ResultA total of 101 non-elderly adult AA patients were enrolled in this study, including 81 in the effective group and 20 in the ineffective group. The effective group had a higher proportion of the patients without a history of drug allergy than the ineffective group (P<0.05). The body height, body weight, gender, age, disease classification, course of disease, family history, and complications showed no significant differences between two groups. The effective group had higher levels of ANC and PLT before treatment (P<0.05) and higher proportion of patients with ANC≥1.6×109/L and PLT≥25×109/L (P<0.05, P<0.01) than the ineffective group. The baseline levels of WBC, HGB, and Ret showed no significant statistical differences between two groups. The levels of CD3+HLA-DR+T cells in the effective group before treatment was higher than that in the ineffective group (P<0.05). The levels of CD3+CD19-T cells, CD4+T cells, CD8+T cells, Th1 cells, Th2 cells, and CD3+CD25+T cells showed no significant statistical differences between two groups before treatment. The proportion of patients with active bone marrow nucleated cells proliferation in the effective group before treatment were significantly higher than that in the ineffective group, while the proportion of patients with reduced or extremely reduced proliferation were significantly lower than that in the ineffective group (P<0.05). The expression levels of T-bet and GATA-3 genes had no significant differences between two groups before treatment. The multivariate binary logistic regression analysis showed that the ANC level before treatment and history of drug allergy were independent influencing factors for efficacy (P<0.05, P<0.01), while other indicators were not influencing factors for efficacy. The receiver operating characteristic (ROC) curve was applied to analyze the predictive value of the ANC level before treatment in the treatment of AA in non-elderly adults with Yiqi Yangxue prescription combined with western medicine. The area under the curve was 0.679 (P<0.05), with the critical value of 1.595×109/L, the sensitivity of 0.42, and the specificity of 0.95. ConclusionThe history of drug allergy, pre-treatment ANC, PLT, CD3+HLA-DR+ T cell levels, and proliferation of nucleated cells in bone marrow before treatment are predictive factors for the efficacy of Yiqi Yangxue prescription combined with western medicine in treating AA in non-elderly adults. This therapy tends to be more effective for the patients with no history of drug allergy, higher ANC and PLT levels before treatment, especially those with ANC≥1.6×109/L, PLT≥25×109/L, and higher CD3+ HLA-DR+T cell levels and the more active proliferation of nucleated cells in bone marrow before treatment.

BACKGROUND:
LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.
METHODS:
We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.
RESULTS:
On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).
CONCLUSION:
LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.

At present, the incidence of Parkinson's disease (PD) is gradually increasing. This seriously affects the quality of life of patients, and the burden of diagnosis and treatment is increasing. However, the disease is difficult to intervene in early stage as early monitoring means are limited. Aiming to find an effective biomarker of PD, this work extracted correlation between each pair of electroencephalogram (EEG) channels for each frequency band using weighted symbolic mutual information and k-means clustering. The results showed that State1 of Beta frequency band ( P = 0.034) and State5 of Gamma frequency band ( P = 0.010) could be used to differentiate health controls and off-medication Parkinson's disease patients. These findings indicated that there were significant differences in the resting channel-wise correlation states between PD patients and healthy subjects. However, no significant differences were found between PD-on and PD-off patients, and between PD-on patients and healthy controls. This may provide a clinical diagnosis reference for Parkinson's disease.

ObjectiveTo explore the effects of Bushen Jianpi prescription on the autophagy and phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway in the patients with aplastic anemia (AA). MethodA total of 30 AA patients admitted to Xiyuan Hospital and 6 healthy donors who were prepared to undergo peripheral blood hematopoietic stem cell transplantation in 304 Hospital from September 2020 to August 2021 were enrolled and assigned into an AA group and a control group. The AA group was treated with Bushen Jianpi prescription combined with cyclosporin A (CsA) and androgen for 3 months. The mononuclear cells from bone marrow in the AA group before and after treatment and the peripheral blood of the control group were collected. Transmission electron microscopy was then employed to detect autophagosomes. Western blotting was employed to determine the protein levels of microtuble-associated protein 1 light chain 3 (LC3)Ⅰ, LC3Ⅱ, mTOR, phosphorylated (p)-mTOR, Akt, p-Akt, PI3K, and p-PI3K, and real-time polymerase chain reaction (PCR) to determine the mRNA levels of LC3, mTOR, Akt, and PI3K. ResultIn the AA group, the treatment was completed in 29 patients, and the total response rate was 51.72% (15/29). ① The AA group showed lower levels of white blood cell (WBC), hemoglobin (HGB), platelet (PLT), and absolute neutrophil count (ANC) in the peripheral blood (P<0.01) and lower number of intracellular autophagosomes than the control group before treatment. Moreover, the AA group showed lower mRNA level of LC3 (P<0.01) and protein levels of LC3Ⅰ and LC3Ⅱ (P<0.01) and higher mRNA levels of mTOR, Akt, and PI3Kα (P<0.01) and protein levels of Akt, p-Akt, PI3K, p-PI3K, mTOR, and p-mTOR (P<0.01) than the control group. ② In AA group, the levels of HGB and PLT elevated (P<0.05) and the number of intracellular autophagosomes increased after treatment compared with those before treatment. Moreover, the mRNA level of LC3 and the protein levels of LC3Ⅰ and LC3Ⅱ were up-regulated (P<0.01), the mRNA levels of mTOR, Akt, and PI3Kα (P<0.01) and the protein levels of Akt, p-PI3K (P<0.01), p-Akt, PI3K, mTOR, p-mTOR (P<0.05) were down-regulated after treatment. ConclusionAA patients show lower autophagy levels, while Bushen Jianpi prescription can effectively improve the autophagy level and down-regulated the expression of PI3K/Akt/mTOR signaling pathway in AA patients.

Objective:To discuss the feasibility and safety of modified side overlap with fundoplication by Yamashita (mSOFY) in laparoscopic proximal gastrectomy.Methods:Using the method of descriptive case series study, the clinical data of 9 patients with upper gastric cancer who successfully performed mSOFY anastomosis from March 2022 to October 2022 in the Affiliated Huaian No.1 People's Hospital of Nanjing Medical University were retrospectively analyzed.The reconstruction steps of mSOFY anastomosis are as follows: (1) Make a small incision on the right side of the esophageal stump and in front of the anterior wall of the gastric stump; (2) The 45mm linear cutting stapler is placed into the preset anastomosis of the esophagus and the remnant stomach, and the esophagus is rotated 90° counterclockwise along the axis, so that the right wall of the esophagus is anastomosed with the remnant stomach, and the stomach wall is sutured to the left side of the esophagus; (3) The common opening of esophagus and remnant stomach was sutured with inverted suture; (4)Suture the left and lower sides of the esophagus with the remnant stomach to make the esophagus flat against the stomach wall; (5) Open the sutured common opening: due to the pressure of the false dome, the posterior wall of the lower esophageal segment was compressed into a valve-like structure. We mainly observing the postoperative reflux and nutritional improvement of the patients, and recording the intraoperative situation and postoperative complications.Results:Nine patients with upper gastric cancer who completed laparoscopic proximal gastrectomy (mSOFY anastomosis) did not have conversion to laparotomy or intraoperative / postoperative complications. The operation time was (169.4±10.4) minutes, the anastomotic reconstruction time was (51.7±7.1) minutes, the intraoperative bleeding volume was (98.9±43.4) ml, and the number of lymph nodes dissected was (27.2±6.7). The patient recovered well after operation, without any complaints related to reflux esophagitis. Postoperative gastrointestinal radiography showed that the anastomosis was smooth, without stenosis and leakage. The serum albumin [(41.6±3.4) L vs. (39.9±2.6) L], prealbumin [(211.3±38.6) mg/L vs. (205.3±36.0) mg/L], and hemoglobin levels [(126.7±13.2) g/L vs. (121.0±9.7) g/L] of patients before and one month after surgery have no statistically significant differences (all P>0.05). Conclusion:mSOFY anastomosis can be used as one of the safe and feasible reconstruction methods in laparoscopic proximal gastrectomy.
