Objective To investigate the association of endometrial thickness(EMT)with obstetric and neonatal outcomes of monoparous pregnancy in fresh cleavage embryos transfer.Methods A total of 1 845 patients of monoparous pregnancy after fresh cleavage embryos transfer cycles from Jan 2016 to Mar 2022 at Shanghai First Maternity and Infant Hospital,Tongji Universtiy were analyzed retrospectively.Patients were categorized into three groups by EMT on transferation day:≤8 mm(group A),8-14 mm(group B)and≥14 mm(group C).The primary outcomes were preterm birth(PTB),birth weight and birth weight z-score,small-for-gestation age,large-for-gestation age,very low birth weight,low birth weight and macrosomia.The second outcomes were pregnancy and perinatal complications.The relationship between EMT and adverse neonatal outcomes was estimated by Logistic regression analysis.Results The rate of ectopic pregnancy was increased significantly in group A.No significant differences were found among the three groups in gestation age,birth weight,birth weight z-score,PTB,small for gestation age,large for gestation age,low birth weight,very low birth weight and macrosomia.Compared with group B,the odds of adverse neonatal outcomes did not show significant differences before and after adjustment in both group A and group C by Logistic regression analysis.Conclusion Thinner EMT in fresh cleavage embryos transfer is associated with higher rate of ectopic pregnancy,while it is not independently associated with adverse perinatal outcomes.

OBJECTIVE: To investigate the clinical characteristics and prognosis of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). METHODS: Clinical data of 10 patients with PTCL-NOS in Gansu Provincial Hospital from May 2016 to June 2023 were collected. The treatment outcomes were evaluated, and the factors affecting prognosis were analyzed. RESULTS: The median age of onset for the 10 patients was 60.7 (47-75) years, with 7 males and 3 females. Nine cases received chemotherapy, while one case died suddenly after diagnosis, and the median course of chemotherapy was 6.9 (1-13) courses. Assessing the efficacy, 3 patients achieved complete remission (CR) while 7 patients showed progression. Age, sex, lactate dehydrogenase (LDH) level, Ki-67 and the presence of hemophagocytic lymphohistocytosis (HLH) were not statistically correlated with CR rate ( P >0.05). Patients with IPI score 3-5, and Ann Arbor stage III-IV had statistically lower CR rates (both P <0.05). Age, B symptoms, LDH level ,hemoglobin, Ki-67 index and PLR value were not statistically correlated with overall survival (OS) time ( P >0.05). Male, platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, presence of HLH, NLR≥4.05, and LMR <2.81 were statistically correlated with shorter OS (all P <0.05). Among the 10 patients, 3 cases have survived and are still in CR status, while 7 cases have died, with a median survival time of 7.5 (1-85) months. CONCLUSIONS Patients with IPI score 3-5 and Ann Arbor stage III-IV have low CR rate and poor prognosis. The OS of patients who are male, with platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, complication of HLH, NLR≥4.05, and LMR <2.81 is short, and prognosis is poor.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Objective:To investigate the clinical characteristics and prognosis of patients with hemophagocytic lymphohistiocytosis(HLH).Methods:Clinical data of 78 patients with HLH admitted to Gansu Provincial People's Hospital from January 2014 to May 2023 were collected,and the correlation between relevant indicators and patient prognosis was analyzed.Results:Among the 78 HLH patients,there were 48 males and 30 females,with a median age of onset of 48(1-84)years old;26 patients were treated with chemotherapy,44 patients were treated with glucocorticoids,immunoglobulin or cyclosporine,5 patients received symptomatic treatment,1 patient received plasma exchange,and 2 patients refused treatment.By the end of the follow-up,there were 39 survivors,35 deaths,and 4 patients lost to follow-up.There was no significant correlation between sex,ferritin,triglycerides,hemophagocytosis,bone marrow cellularity,Epstein-Barr virus(EBV)infection,SUV value of PET-CT,alanine aminotransferase(ALT),interleukin-6(IL-6),platelet-to-lymphocyte ratio(PLR)and overall survival(OS)of the patients(P＞0.05).Patients with age ≥ 60 years,neutrophil-to-lymphocyte ratio(NLR)＞0.59,red cell distribution width-to-platelet ratio(RPR)＞0.30,lymphocyte-to-monocyte ratio(LMR)≤ 2.74,red blood cell distribution width(RDW)＞16.45％,tumor-associated HLH,aspartate aminotransferase(AST)≥ 148 U/L,procalcitonin(PCT)≥ 0.66 ng/ml,neutrophils(NEU)＜2 × 109/L,fibrinogen(FIB)＜1.85 g/L,lactate dehydrogenase(LDH)≥ 1 740 U/L,hemoglobin(Hb)＜85 g/L,platelet(PLT)＜57 × 109/L had significantly shorter OS,with statistical significance(P＜0.05).Multivariate analysis showed that LMR ≤ 2.74,RDW＞16.45％,LDH ≥ 1 740 U/L,and NEU＜2 × 109/L were independent risk factors affecting OS in HLH patients(P＜0.05).Conclusion:Some blood-based inflammatory markers are significantly associated with OS in patients with HLH.NLR,RPR,LMR,RDW and PCT can be used to assess the prognosis of HLH patients,and RDW and LMR are independent factors affecting OS of HLH patients,which provide greater predictive value for prognosis.Hypercellular bone marrow in HLH patients may indicate a poor prognosis.

AIM:To investigate the effect of a disintegrin and metalloproteinase(ADAM)domain-like decy-sin 1(ADAMDEC1)knockdown on the proliferation,migration and invasion of pancreatic carcinoma cells.METHODS:Expression levels of ADAMDEC1 in pancreatic carcinoma tissues were analyzed using the GEPIA and UALCAN online da-tabases.Western blot analysis was employed to detect the protein expression levels of ADAMDEC1 in pancreatic carcino-ma cell lines(MIA PaCa-2 and PANC-1)and pancreatic ductal cell line(hTERT-HPNE).The effects of ADAMDEC1 knockdown on cell proliferation,migration and invasion were evaluated using CCK-8,colony formation,wound-healing and Transwell assays.Additionally,Western blot analysis was used to detect the effects of ADAMDEC1 knockdown on the expression levels of migration and invasion markers,as well as Wnt/β-catenin signaling pathway-related proteins in pancre-atic carcinoma cells.Furthermore,a recovery experiment was conducted to assess the role of Wnt/β-catenin signaling path-way agonist CHIR-99021 in ADAMDEC1 knockdown-induced inhibition of pancreatic carcinoma cell growth and migra-tion.RESULTS:(1)ADAMDEC1 was highly expressed in pancreatic carcinoma cells.(2)Knockdown of ADAMDEC1 led to a significant reduction in the proliferation,migration and invasion of pancreatic carcinoma cells.(3)Knockdown of ADAMDEC1 resulted in increased E-cadherin protein expression and decreased levels of matrix metalloproteinase 9,N-cadherin and vimentin proteins,alongside a reduction in the expression of Wnt/β-catenin signaling pathway-related pro-teins.(4)Co-treatment of pancreatic carcinoma cells with CHIR-99021 and ADAMDEC1 small interfering RNA reversed the inhibitory effects of ADAMDEC1 knockdown on cell proliferation,migration,and invasion.CONCLUSION:ADAMDEC1 is highly expressed in pancreatic carcinoma.Targeted silencing of ADAMDEC1 has the potential to inhibit the prolifera-tion,migration and invasion of pancreatic carcinoma cells by regulating the Wnt/β-catenin signaling pathway.

Objective To investigate the effect of amygdalin(AD)on fracture healing in osteoporotic(OP)rats and its possible mechanism.Methods SD rats were randomly divided into sham group,model group,inhibitor group and low,medium,high dose experimental groups,12 rats in each group.The OP rat model was established by bilateral ovariectomy.After the model was successfully established,rats in low,medium and high dose experimental groups were intraperitoneally injected with 0.1,0.5 and 1.0 mg·kg-1 AD;the inhibitor group was intraperitoneally injected with 5.0 mg·kg-1 H-89[cyclic adenosine monophosphate/protein kinase A/cyclic adenosine monophosphate response element binding protein(cAMP/PKA/CREB)pathway inhibitor]+1.0 mg·kg-1 AD;sham group and model group were intraperitoneally injected with the same amount of 0.9％NaCl,once a day for 90 days.Micro-computer tomography was applied to observe the microstructure of the epiphysis in rats;the biomechanical status of femur was evaluated by orthopedic biomechanical test;the contents of serum osteocalcin(OC),C-terminal telopeptides of type Ⅰ collagen(CTX-Ⅰ),bone morphogenetic protein 2(BMP-2)and cAMP were detected by enzyme-linked immunosorbent assay(ELISA);the level of oxidative stress products in rat serum was detected by kit;Western blot was used to detect the expression of alkaline phosphatase(ALP)and cAMP/PKA/CREB signaling pathway protein(p-PKA/PKA,p-CREB/CREB)in rat bone tissue.Results The bone mineral density of sham group,model group and low,medium,high dose experimental groups,inhibitor group were(251.54±15.41),(135.82±10.92),(173.57±12.65),(204.31±14.48),(235.62±11.37)and(187.83±13.64)mg·cm-3;the contents of cAMP were(0.85±0.06),(0.20±0.03),(0.34±0.07),(0.48±0.09),(0.81±0.12)and(0.57±0.06)μmol·L-1;the expression of p-PKA/PKA were 0.96±0.08,0.06±0.02,0.35±0.04,0.67±0.07,0.94±0.09 and 0.37±0.05;p-CREB/CREB protein were 0.92±0.12,0.04±0.01,0.28±0.03,0.59±0.06,0.91±0.10 and 0.29±0.04,respectively.There were significant differences in the above indexes between sham group and model group,between low,medium,high dose experimental groups and model group,between inhibitor group and high dose experimental group(all P＜0.05).Conclusion AD can reduce oxidative stress,promote fracture healing and alleviate OP symptoms in rats.The mechanism may be related to the activation of cAMP/PKA/CREB signaling pathway.

Based on the literature study,the thoughts and possible therapeutic mechanism in treating male infertility from the perspective of spleen and kidney by regulating intestinal flora were explored.Disturbance of intestinal flora is one of the important factors leading to the development of male infertility,and the spleen and kidney have certain similarities to intestinal flora in the physiological function and pathological changes.Moreover,tonifying the kidney and strengthening the spleen can regulate the intestinal flora by fostering the growth of beneficial bacteria,inhibiting the reproduction of pathogenic bacteria,and protecting the barrier of the intestinal mucosa.Therefore,the possible therapeutic mechanisms in treating male infertility with the prescriptions for tonifying the kidney and strengthening the spleen to regulate intestinal flora are as follows:inhibiting the expression of inflammatory factors to reduce the inflammatory reaction of testicular tissues;improving the antioxidant capacity to alleviate the damage of spermatozoa caused by oxidative stress,and improving the bad mood to alleviate the impact of psychological stress on the reproductive system.The exploration of the thoughts for treating male infertility from the perspective of spleen and kidney by regulating intestinal flora may provide a new entry point for modern Chinese medicine clinical treatment of male infertility.

Objective To investigate the short-term efficacy and safety of chemotherapy induced by nimotuzumab(NTZ)combined with TP regimen and sequential concurrent chemoradiotherapy in patients with epidermal growth factor receptor positive(EGFR-positive)locally advanced nasopharyngeal carcinoma.Methods A total of 48 patients with stage Ⅲ to Ⅳ A nasopharyngeal carcinoma in Guizhou Provincial People's Hospital from January 2020 to December 2022 were prospectively enrolled,and were randomized into two groups:NTP(NTZ+docetaxel/albumin-paclitaxel+cisplatin)group and TP(Docetaxel/albumin-paclitaxel+cisplatin)group(24 cases per group)by random number table method.After 2 or 3 cycles of induction chemotherapy in NTP group,NTZ was sequentially used in combination with cisplatin for concurrent chemoradiotherapy.Immunohistochemistry was used to detect the EGFR expression level,exploring EGFR expression intensity and the therapeutic effect of NTZ in NTP group patients.Meanwhile,short-term efficacy,withdrawal rate and toxic side effects were compared between the two groups after induction chemotherapy.Results In NTP group,the positive expression rate of EGFR was 100％,and EGFR expression intensity significantly correlated with the efficacy of NTZ-combined induction therapy(P<0.05).After induction chemotherapy,the objective response rate(ORR)of cervical lymph nodes in NTP group was significantly higher than that in TP group(75％vs.45.8％,P=0.039).The primary lesion ORR and overall(primary lesion and cervical lymph node)ORR showed no significant difference between the two groups(P>0.05).Comparison of adverse reactions between the two groups during induction therapy:leukopenia and gastrointestinal reaction in NTP group were lower than those in TP group(P<0.05),but rash was higher than those in TP group(P<0.05).There was no significant difference in liver function,hemoglobin and thrombocytopenia between two groups(P>0.05).Conclusions EGFR expression intensity varies in nasopharyngeal carcinoma tissues,with higher levels indicating greater clinical benefit of combined induction therapy with NTZ.NTZ combined with TP induction regimen demonstrates good short-term efficacy and safety for cervical lymph nodes in patients with locally advanced nasopharyngeal carcinoma.

Objective:To analyze the clinical characteristics and prognosis of patients with CD5+diffuse large B-cell lymphoma(DLBCL).Methods:The clinical data of 161 newly treated DLBCL patients in Gansu Provincial Hospital from January 2013 to January 2020 were retrospectively analyzed.According to CD5 expression,the patients were divided into CD5+group and CD5-group.The clinical characteristics and prognosis of the two groups were statistically analyzed.Results:The median age of patients in CD5+group was 62 years,which was higher than 56 years in CD5-group(P=0.048).The proportion of women in CD5+group was 62.96％,which was significantly higher than 41.79％in CD5-group(P=0.043).The proportion of patients with IPI score＞2 in CD5+group was 62.96％,which was higher than 40.30％in CD5-group(P=0.031).Survival analysis showed that the median overall survival and progression-free survival time of patients in CD5+group were 27(3-77)and 31(3-76)months,respectively,which were both shorter than 30(5-84)and 32.5(4-83)months in CD5-group(P=0.047,P=0.026).Univariate analysis showed that advanced age,positive CD5 expression,triple or double hit at initial diagnosis,high IPI score and no use of rituximab during chemotherapy were risk factors for the prognosis of DLBCL patients.Further Cox multivariate regression analysis showed that these factors were also independent risk factors except for advanced age.Conclusion:CD5+DLBCL patients have a worse prognosis than CD5-DLBCL patients.Such patients are more common in females,with advanced age and high IPI score,which is a special subtype of DLBCL.
