OBJECTIVE: To study the efficacy and prognosis of patients with myelodysplastic/myeloproliferative neoplasms (MDS/MPN) treated with hypomethylating agents (HMA), and to analyze the factors that may affect their efficacy and prognosis, in order to provide a clinical basis for the choice of treatment options for patients with MDS/MPN. METHODS: 35 patients with newly diagnosed MDS/MPN who received hypomethylating therapy from January 2018 to April 2024 in the Department of Hematology of Affiliated Hospital of Xuzhou Medical University were included. The patients were divided into decitabine group (15 cases) and azacitidine group (20 cases) according to the treatment regimen. The efficacy, median overall survival (OS), and median progression-free survival (PFS) of the patients after HMA treatment were evaluated. The differences in efficacy and survival between the two groups were compared, and factors affecting efficacy and prognosis of MDS/MPN patients were analyzed. RESULTS: The overall response rate (ORR) of the 35 MDS/MPN patients treated with HMA was 51.4%. The ORR was 73.3% in decitabine group and 35.0% in azacitidine group, with a statistically significant difference (P =0.041). Survival analysis showed that the median OS was 12 months and the median PFS was 10 months in the entire cohort of the patients. There was no difference in median OS between decitabine group and azacitidine group. The median PFS in decitabine group was 12 months, higher than that in azacitidine group (7 months), but the difference was not statistically significant (P =0.505). Multivariate analysis showed that the treatment regimen and platelet count were independent influencing factors for the efficacy of HAM treatment; The course and therapeutic efficacy of HMA treatment were independent influencing factors for OS in MDS/MPN patients. The main adverse reactions of HMA treatment were myelosuppression and pulmonary infection. Gastrointestinal reactions were more likely to occur in the azacitidine group than in the decitabine group, and the difference was statistically significant (P =0.027). CONCLUSION HMA treatment is effective and well-tolerated in some MDS/MPN patients. Decitabine shows superior efficacy compared with azacitidine and is less likely to cause gastrointestinal reactions. Patients who received ≥4 courses of HMAs and responded to hypomethylating therapy had longer OS.

Objective To explore clinical outcomes and bone resection of interlaminar fenestration decompression and u-nilateral biportal endoscopic(UBE)technique in treating lumbar disc herniation(LDH).Methods A retrospective study was performed on 105 patients with single-level LDH treated from December 2019 to December 2021.Fifty-four patients in UBE group,including 32 males and 22 females,aged from 18 to 50 years old with an average of(38.7±9.3)years old,were treated with UBE,29 patients withL4.5and 25 patients with L5S1.There were 51 patients in small fenestration group,including 27 males and 24 females,aged from 18 to 50 years old with an average of(39.9±10.0)years old,were treated with small fenestra-tion,25 patients with L4.5 and 26 patients with L5S1.Perioperative indexes,such as operation time,postoperative time of getting out of bed and hospital stay were observed and compared between two groups.Visual analogue scale(VAS)and Oswestry dis-ability index(ODI)were compared between two groups before operation and 1,3,6 and 12 months after operation,respective-ly;and modified MacNab evaluation criteria was used to evaluate clinical efficacy.Amount of bone resection and retention rate of inferior articular process laminoid complex were compared between two groups.Results All 105 patients were successfully completed operation.Both of two groups were followed up from 6 to 12 months with an average of(10.69±2.49)months.Oper-ation time,postoperative time of getting out of bed and hospital stay were(58.20±5.54)min,(2.40±0.57)dand(3.80±0.61)d in UBE group,and(62.90±7.14)min,(4.40±0.64)d and(4.40±0.64)d in small fenestrum group,respectively;and had sta-tistically difference between two groups(P＜0.05).Postoperative VAS of low back and leg pain and ODI in both groups were significantly lower than those before surgery(P＜0.05).VAS of lumbar pain in UBE group(1.37±0.49)score was lower than that of small fenestration group(2.45±0.64)score,and had statistically difference(t=9.745,P＜0.05).Postoperative ODI in UBE group at 1 and 3 months were(28.54±3.31)％and(22.87±3.23)％,respectively,which were lower than those in small fenestra group(36.31±9.08)％and(29.90±8.36)％,and the difference was statistically significant(P＜0.05).There were no significant difference in VAS and ODI between two groups at other time points(P＞0.05).According to the modified MacNab evaluation criteria at the latest follow-up,49 patients got excellent result,3 good,and 2 fair in UBE group.In small fenestration group,35 patients got excellent,12 good,and 4 fair.In UBE group,amount of bone resection on L4,5 segment was(0.45±0.08)cm3 and(0.31±0.08)cm3 on the segment of L5S1.In small fenestration group,amount of bone resection on L4.5 segment was(0.57±0.07)cm3 and(0.49±0.04)cm3 on the segment of L5S1,and amount of bone resection of lower articular process laminar complex on the same segment in UBE group was less than that in small fenestration group(P＜0.05).In UBE group,retention rate of laminoid complex on L4,5 segment was(0.73±0.04)and L5S1 segment was(0.83±0.03),whileL4,5segment was(0.68± 0.06)and L5S1 segment was(0.74±0.04)in small fenestration group,the lower articular process laminar complex retention rate in UBE group was higher than that in small fenestration group(P＜0.05).Conclusion Both unilateral double-channel endoscopy and small fenestration of laminae could achieve good clinical results in treating LDH,but UBE has advantages of less trauma,higher eficiency,faster postoperative recovery and less damage to bone structure.

ObjectiveTo further study the pathogenic role of different types of Chlamydia trachomatis （CT） proteins in tubal factor infertility， evaluate the clinical detection value of Chlamydia trachomatis protein antibody in predicting tubal factor infertility. MethodsA total of 58 cases of tubal factor infertility （TFI）， 41 cases of fertile controls （FC） and 18 cases of infertile controls （IFC） were included. For serum detection， first， CT-IgG ELISA kit was used to detect the expression of CT-IgG in serum of three groups of people； then， 6 kinds of Chlamydia trachomatis proteins were expressed and purified in the early stage to establish the antibody test for these proteins， and ELISA detection method was used to detect the expression of their antibodies in the serum of TFI group， FC group and IFC group， respectively； and finally， the antibody OD value of the 6 kinds of Chlamydia trachomatis proteins in the three groups of subjects were statistically described， and CT-IgG was used as the reference standard to draw the receiver operating characteristic curve （ROC curve） of each CT antibody. The Youden Index determines the cutoff value for each antibody. Taking TFI as the reference class， two disordered multiple classification logistic regression models were established with the FC and IFC groups， respectively； and the reference class was used to explore the value of various antibodies and age in predicting TFI， FC and IFC of Chlamydia trachomatis. The back-off method was used to screen the variables. ResultsThe OD value of CT376 antibody in the TFI group was higher than that in the FC group （0.86 vs. 0.60， P=0.026）. The CT376 antibody OD value in the TFI group was higher than that in the IFC group （0.86 vs. 0.64， P=0.026）. The CT443 antibody OD value in the IFC group was higher than that in the TFI group （0.59 vs. 0.34， P=0.036） and higher than that in the FC group （0.59 vs. 0.30， P=0.02）. The multiple classification logistic regression analysis established between TFI and FC showed that CT-IgG ［P<0.001， OR=0.084， 95%CI （0.025， 0.284）］， CT376 antibody ［P=0.068， OR=0.359， 95%CI （0.120， 1.078）］. CT-IgG is an independent risk factor for tubal infertility， and CT376 antibody cannot be an independent risk factor for tubal infertility. The multiple classification logistic regression analysis established between TFI and IFC showed that among infertile patients， CT-IgG ［P<0.05， OR=0.194， 95%CI （0.046， 0.817）］， CT376 antibody ［P<0.05， OR=0.176， 95%CI （0.038， 0.818）］ and CT381 antibody ［P<0.05， OR=0.112， 95%CI （ 0.016， 0.796）］ were independent risk factors for tubal infertility. ConclusionThe expression of CT376 antibody in tubal infertility patients is higher than that in fertile and infertile controls， suggesting that CT-induced tubal factor infertility may be related to CT376. CT-IgG， and CT376 antibodies are meaningful in predicting CT-induced tubal factor infertility.

Astragali Radix-Curcumae Rhizoma(AR-CR) is a combination commonly used in the clinical treatment of tumors. Based on the T helper 17(Th17)/regulatory T cell(Treg) balance, the present study explored the possible mechanism of AR-CR combined with 5-fluorouracil(5-FU) on the tumor growth of orthotopic xenograft model mice of colorectal carcinoma. Ninety male BALB/c mice were randomly divided into nine groups, i.e., a blank group, a model group, a 5-FU group, high-, medium-, and low-dose AR-CR(2∶1) groups, and high-, medium-, and low-dose AR-CR+5-FU groups, with 10 mice in each group. The orthotopic xenograft model of CT26.WT colorectal carcinoma was induced in mice except those in the blank group. Twenty-four hours after the ope-ration, mice in the blank group and the model group received normal saline by gavage(10 mL·kg~(-1), once per day), and those in the 5-FU group received 5-FU by intraperitoneal injection(25 mg·kg~(-1), once every other day). Mice in the AR-CR groups received AR and CR decoctions by gavage(12, 6, and 3 g·kg~(-1), once a day) and those in the combination groups received AR and CR decoctions and 5-FU(doses and administration methods were the same as above). After intervention for three weeks, all mice were sacrificed and tumor tissues were collected. The tumor mass was weighed and the average tumor weight was calculated. The changing trend of Th17/Treg(%) in the CD4~+T lymphocytes of the spleen tissues of the mice in each group was detected. The mRNA expression in the blood and protein expression in the tumor tissues of transforming growth factor-β(TGF-β), tumor necrosis factor-α(TNF-α), interferon-γ(IFN-γ), Smad4, N-cadherin, matrix metalloproteinase-7(MMP-7) were detected. The experimental results revealed that compared with the model group, the groups with drug intervention showed reduced tumor mass(P<0.01), decreased CD4~+IL-17~+ in the spleen tissues to varying degrees(P<0.001), and increased proportion of CD4~+Foxp3~+(P<0.001 or P<0.05), indicating that Th17/Treg maintained dynamic balance, and the effect of the combination groups was predominant. Additionally, the mRNA expression in the blood and protein expression in the tumor tissues of TGF-β, TNF-α, IFN-γ, Smad4, N-cadherin, and MMP-7 declined to varying degrees in a dose-dependent manner(P<0.01 or P<0.001). The AR-CR combined with 5-FU can inhibit the tumor growth of orthotopic xenograft model mice of CT26.WT colorectal carcinoma. The mechanism may be related to maintenance of Th17/Treg dynamic balance in the body and down-regulation of TGF-β, TNF-α, IFN-γ, Smad4, N-cadherin, and MMP-7 expression.

OBJECTIVE: To investigate the correlation between pretransplant serum ferritin (SF) level and prolonged or prolonged isolated thrombocytopenia (PT) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: The clinical data of 35 patients with PT after allo-HSCT were retrospectively analyzed, and 35 patients were matched according to age and sex as a controls from 424 allo-HSCT patients with normal platelet count. The serum ferritin level before the transplantation was analyzed. The potential risk factors were analyzed by chi-square test and Fisher's exact test as well as univariate and multivariate logistic regression. The survival curve was estimated by the Kaplan-Meier model to explore its clinical significance. In addition, ROC curve was used to verify the predictive power of SF. RESULTS: Compared with control group, the SF level in the PT group before transplantation significantly increased (P=0.001). Multivariate analysis results showed that SF level before transplantation was a risk factor for prolonged thrombocytopenia after HSCT, and patients with SF≥1000 ng / ml showed a higher risk of death (P=0.014). ROC curve showed that SF level could be used as a predictor of prolonged thrombocytopenia after allo-HSCT. CONCLUSION The SF level before allo-HSCT relates with occurrence and prognosis of PT in patients after allo-HSCT. Detection of SF level can provide guidance for the intervention of prolonged thrombocytopenia after HSCT.

OBJECTIVE: To compare the efficacy of haploidentical hematopoietic stem cell transplantation (hi-HSCT) HLA-matched sibling donor hematopoietic stem cell transplantation (MSD-HSCT) and post-remission chemotherapy (PR-CT) in treatment of intermediate risk acute myeloid leukemia with negative for FLT3-ITD, NPM1 or biallelic CEBPA mutation. METHODS: The clinical data of patients with intermediate risk NPM1/non-CEBPA/FLT3-ITD AML from October 2009 to May 2016 were retrospectively analyzed. RESULTS: The overall survival rate of the patients treated with PR-CT, MSD-HSCT or hi-HSCT was 63.7%, 71.7%, 75.5%, respectively (P＜0.05); the disease-free survival (DFS) rate was 52.8%, 67.1%, 71.3% respectively (P＜0.001); the cumulative incidence of relapse was 24.7%, 16.9%, 14.4% respectively (P＜0.05); the non-relapse mortality was 26.2%, 17.3%, 14.4% reapectively (P＞0.05). The analysis of transplantation, related adverse events showed that II-IV grade of aGVHD in the MSD-HSCT group and hi-HSCT group was 48.9% and 45.6% respectively (P＞0.05); the extensive cGVHD event was 21.6% and 8.8% (P＜0.05) respectively. CONCLUSION The efficiency of hi-HSCT and MSD-HSCT is superior to that of PR-CT for treatment of patients with intermediate risk NPM1/non-CEBPA/FLT3-ITD AML after CR1, there is no statistically significant difference in the efficiency of consolidatorg treatment and the transplantation-related mortality between hi-HSCT and MSD-HSCT.

Phytochemical investigation of the leaves and twigs of Callicarpa cathayana led to the isolation of six new clerodane diterpenoids, cathayanalactones A-F (1-6), together with seven analogues (7-13). Their structures were established by extensive NMR analyses together with experimental and calculated ECD spectra analyses. Compounds 1, 2, 3, 7 and 11 showed inhibitory activities on lipopolysaccharide-induced nitric oxide production in RAW264.7 cells.

ObjectiveTo investigate the protective effect of human urine-derived stem cells (USCs) on erectile function and cavernous structure in rats with cavernous nerve injury (CNI).

METHODSSixty adult male SD rats with normal sexual function were randomly divided into four groups of equal number: sham operation, bilateral CNI (BCNI) model control, phosphate buffered saline (PBS), and USC. The BCNI model was established in the latter three groups of rats by clamping the bilateral cavernous nerves. After modeling, the rats in the PBS and USC groups were treated by intracavernous injection of PBS at 200 μl and USCs at 1×106/200 μl PBS respectively for 28 days. Then, the maximum intracavernous pressure (mICP) and the ratio of mICP to mean arterial pressure (mICP/MAP) of the rats were calculated by electrical stimulation of the major pelvic ganglions, the proportion of nNOS- or NF200-positive nerve fibers in the total area of penile dorsal nerves determined by immunohistochemical staining, the levels of endothelial cell marker eNOS, smooth muscle marker α-SMA and collagen I detected by Western blot, and the smooth muscle to collagen ratio and the cell apoptosis rate in the corpus cavernosum measured by Masson staining and TUNEL, respectively.

RESULTSAfter 28 days of treatment, the rats in the USC group, as compared with those in the PBS and BCNI model control groups, showed significant increases in the mICP (［81 ± 9.9］ vs ［31 ± 8.3］ and ［33 ± 4.2］ mmHg, P <0.05), mICP/MAP ratio (0.72 ± 0.05 vs 0.36 ± 0.03 and 0.35 ± 0.04, P <0.05), the proportions of nNOS-positive nerve fibers (［11.31 ± 4.22］% vs ［6.86 ± 3.08］% and ［7.29 ± 4.84］% , P <0.05) and NF200-positive nerve fibers in the total area of penile dorsal nerves (［27.31 ± 3.12］% vs ［17.38 ± 2.87］% and ［19.49 ± 4.92］%, P <0.05), the eNOS/GAPDH ratio (0.52 ± 0.08 vs 0.31 ± 0.06 and 0.33 ± 0.07, P <0.05), and the α-SMA/GAPDH ratio (1.01 ± 0.09 vs 0.36 ± 0.05 and 0.38 ± 0.04, P <0.05), but a remarkable decrease in the collagen I/GAPDH ratio (0.28 ± 0.06 vs 0.68 ± 0.04 and 0.70 ± 0.10, P <0.05). The ratio of smooth muscle to collagen in the corpus cavernosum was significantly higher in the USC than in the PBS and BCNI model control groups (17.91 ± 2.86 vs 7.70 ± 3.12 and 8.21 ± 3.83, P <0.05) while the rate of cell apoptosis markedly lower in the former than in the latter two (3.31 ± 0.83 vs 9.82 ± 0.76, P <0.01; 3.31 ± 0.83 vs 9.75 ± 0.91, P <0.05).

CONCLUSIONSIntracavernous injection of USCs can protect the erectile function of the rat with cavernous nerve injury by protecting the nerves, improving the endothelial function, alleviating fibrosis and inhibiting cell apoptosis in the cavernous tissue.

To clarify the clinical application of the group standard (T/CACM 1035-2017) of the Chinese Society of Traditional Chinese Medicine (TCM), the clinical practice guideline on traditional chinese medicine therapy alone or combined with community acquired pneumonia, and to understand the clinical applicability of the Guideline. The clinical workers trained in terms of the Guideline in hospitals at all levels in China were selected as the research objects. A total of 494 questionnaires on application evaluation and 511 questionnaires on applicability evaluation were collected to construct the database of the post-effect evaluation of the Guideline. Excel software was used for statistical analysis. The overall evaluation of the Guideline was 92.31%, 91.06%, 87.45% respectively in efficacy, safety and economy. The Guideline was well used in clinical application, and 99.41% of the patients were willing to follow the recommended scheme. The agreed ratio in rationality evaluation was 97.98%, 92.37%, 94.53% and 92.71% in treatment rules, syndrome differentiation and classification, prevention of complications, and rehabilitation method. The effective rate of the prescriptions recommended in the Guideline was all above 65%. More than 80% of the prescriptions were Tanreqing Injection, Yinqiao Powder, Qingjin Huatan Decoction, Maxing Shigan Decoction, Shengmai San and Shashen Maidong Decoction. Adverse reactions, unknown active components and economy of Chinese patent medicines were the important factors affecting drug use and efficacy, providing a clinical basis for updating and revising the standard.
