Objective: To compare the effects and safety of dydrogesterone (DG) and medroxyprogesterone acetate (MPA) on the treatment in patients with endometrial hyperplasia without atypia (EH). Methods: This was a single-center, open-label, prospective non-inferior randomized controlled phase Ⅲ trial. From February 2019 to November 2021, patients with EH admitted to the Obstetrics and Gynecology Hospital of Fudan University were recruited. Enrolled patients were stratified according to the pathological types of simple hyperplasia (SH) or complex hyperplasia (CH), and were randomised to receive MPA or DG. Untill May 14, 2022, the median follow-up time after complete response (CR) was 9.3 months (1.1-17.2 months). The primary endpoint was the 6-month CR rate (6m-CR rate). The secondary endpoints included the 3-month CR rate (3m-CR rate), adverse events rate, recurrence rate, and pregnancy rate in one year after CR. Results: (1) A total of 292 patients with EH were enrolled in the study with the median age of 39 years (31-45 years). A total of 135 SH patients were randomly assigned to MPA group (n=67) and DG group (n=68), and 157 CH patients were randomly assigned to MPA group (n=79) and DG group (n=78). (2) Among 292 patients, 205 patients enrolled into the primary endpoint analysis, including 92 SH patients and 113 CH patients, with 100 patients in MPA group and 105 in DG group, respectively. The 6m-CR rate of MPA group and DG group were 90.0% (90/100) and 88.6% (93/105) respectively, and there were no statistical significance (χ²=0.11, P=0.741), with the rate difference (RD) was -1.4% (95%CI:-9.9%-7.0%). Stratified by the pathology types, the 6m-CR rate of SH patients was 93.5% (86/92), and MPA group and DG group were respectively 91.1% (41/45) and 95.7% (45/47); and the 6m-CR rate of CH patients was 85.8% (97/113), and MPA group and DG group were 89.1% (49/55) and 82.8% (48/58) respectively. The 6m-CR rates of the two treatments had no statistical significance either (all P>0.05). A total of 194 EH patients enrolled into the secondary endpoint analysis, including 88 SH patients and 106 CH patients, and 96 patients in MPA group and 98 in DG group, respectively. The 3m-CR rate of SH patients were 87.5% (77/88), while the 3m-CR rates of MPA group and DG group were 90.7% (39/43) and 84.4% (38/45), respectively; the 3m-CR rate of CH patients was 66.0% (70/106), and MPA group and DG group had the same 3m-CR rate of 66.0% (35/53). No statistical significance was found between the two treatments both in SH and CH patients (all P>0.05). (3) The incidence of adverse events between MPA group and DG group had no statistical significance (P>0.05). (4) A total of 93 SH patients achieved CR, and the cumulative recurrence rate in one year after CR were 5.9% and 0 in MPA group and DG group, respectively. While 112 CH patients achieved CR, and the cumulative recurrence rate in one year after CR were 8.8% and 6.5% in MPA group and DG group, respectively. There were no statistical significance between two treatment groups (all P>0.05). Among the 93 SH patients, 10 patients had family planning but no pregnancy happened during the follow-up period. Among the 112 CH patients, 21 were actively preparing for pregnancy, and the pregnancy rate and live-birth rate in one year after CR in MPA group were 7/9 and 2/7, while in DG group were respectively 4/12 and 2/4, and there were no statistical significance in pregnancy rate and live-birth rate between the two treatment groups (all P>0.05). Conclusions: Compared with MPA, DG is of good efficacy and safety in treating EH. DG is a favorable alternative treatment for EH patients.

Objective: To analyze the follow-up and clinical effect of multidisciplinary treatment on the children with spinal muscular atrophy (SMA). Methods: The clinical data including nutritional status, respiratory function, bone health and motor function of 45 children with SMA who received multidisciplinary management 1-year follow-up in the Children's Hospital, Zhejiang University School of Medicine from July 2019 to October 2021 were retrospectively collected. Comparisons before and after management were performed using paired-samples t-test or Wilcoxon rank-sum test, etc. Results: The age of 45 patients (25 boys and 20 girls) was 50.4 (33.6, 84.0) months at the enrollment, with 6 cases of type 1, 22 cases of type 2, and 17 cases of type 3 respectively. After the multidisciplinary management, the cases of SMA patients with malnutrition decreased from 22 to 12 (P=0.030), the level of vitamin D were significantly increased ((45±17) vs. (48±14) nmol/L, t=-4.13, P<0.001). There was no significant difference in the forced vital capacity %pred, the forced expiratory volume at 1 second %pred, and the peak expiratory flow %pred ((76±19)% and (76±21)%, (81±18)% and (79±18)%, (81±21)% and (78±17)%; t=-0.24, 1.36, 1.21; all P>0.05). The Cobbs angle of scoliosis also improved significantly (8.0°(0°, 13.0°) vs. 10.0°(0°, 18.5°), Z=-3.01, P=0.003). The Hammersmith functional motor scale expanded scores of children with SMA type 2 and type 3 both showed significant elevation (11.0 (8.0, 18.0) vs. 11.0 (5.0, 18.5) scores, 44.0 (36.5, 53.0) vs. 44.0 (34.0, 51.5) scores, Z=2.44, 3.11, P=0.015, 0.002). Conclusion: Multidisciplinary management is beneficial for delaying the progression of the multi-system impairments of SMA patients, such as malnutrition, restrictive ventilation dysfunction and scoliosis.

Objective: To understand the consciousness of the cancer early treatment and its demographic and socioeconomic factors. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The questionnaire collected personal information, the consciousness of the cancer early treatment and relevant factors. The Chi square test was used to compare the difference between the consciousness of the cancer early treatment and relevant factors among the four groups. The logistic regression model was used to analyze the influencing factors related to the consciousness of the cancer early treatment. Results: With the assumption of being diagnosed as precancer or cancer, 89.97% of community residents, 91.84% of cancer risk assessment/screening population, 93.00% of cancer patients and 91.52% of occupational population would accept active treatments (P<0.001). If the immediate family members were diagnosed as precancer or cancer, people who would encourage their family members to receive early treatment in the four groups accounted for 91.96%, 91.94%, 92.44% and 91.55%, respectively (P<0.001). The company employees, annual household income with 40 000 yuan and more and other three groups had a relatively better consciousness of the cancer early treatment (P<0.05). Male, widowed, unemployed and from the central and western regions had a relatively worse consciousness of the cancer early treatment (P<0.05). Conclusion Residents in urban China participants had a good consciousness of the cancer early treatment. The marital status, occupation, annual household income and residential regions were major factors related to the consciousness of the cancer early treatment.

OBJECTIVE: To explore the role of bone marrow niche in the chemotherapy resistance of patient with acute myeloid leukemia (AML), and to investigate the effects of the MSCs on the apoptosis of HL-60 cell and its underlying mechanisms. METHODS: MSCs were derived from the bone marrow of newly diagnosed AML patients (AML-MSCs) and health donors(MSCs) were co-cultured with HL-60 cells respectively. The apoptosis of HL-60 cells in the presence/absence of MSCs and/or Daunorubicin were determined by flow cytometry with Annexin V/PI double staining. In addition, the morphological features of HL-60 cells were observed by Wright-Giemsa staining, and the ratio of blasts and differentiated cells were counted. Furthermore, the expressions of apoptosis-related factors including Caspase-3, Caspase-8,Caspase-9 and Survivin were detected by Western blot. RESULTS: The flow cytometry showed that there was no significant change in apoptosis of HL-60 cells co-cultured with MSC derived from healthy donors or AML patients. After adding Daunorubicin into different cultural systems, the apoptotic rates of HL-60, HL-60 co-cultured with normal MSCs and HL-60 co-cultured with AML-MSCs were (49.57±7.44)%, (30.72±4.05)% and (22.99±4.08)%, respectively, which showed that normal MSCs and AML-MSCs could remarkably supress Daunorubicin-induced HL-60 apoptosis, however, there was no statistically significant difference of apoptosis between HL-60 co-cultured with normal MSCs and HL-60 co-cultured with AML-MSCs. Wright-Giemsa staining showed that most of the HL-60 cells co-cultured with AML-MSCs were primitive, and cell differentiation was unusual. In AML-MSCs co-cultured group, the cell apoptosis and differentiation caused by DNR was significant decreased, and most of HL-60 cells were initial. Western blot showed that the cleavage activity of Caspase-3 of HL-60 in AML-MSCs and normal MSCs co-cultured group was decreased, compared with HL-60 in single cultured group, moreover, the decrease was significantly in AML-MSC group. Additionally, the expression of survivin in AML-MSCs and normal MSCs co-cultured group was increased, compared with that in single cultured group, and increase was significant in AML-MSCs group. CONCLUSION MSCs can suppress Daunorubicin-induced HL-60 apoptosis via inhibiting Caspase-3 and maintaining survivin level.

OBJECTIVE: To study the influence of acute myeloid leukemia (AML) microenvironment on mesenchymal stem cells (MSCs). METHODS: MSCs were isolated from the bone marrow of newly diagnosed AML patients (AML-MSCs) and were cultured. The morphology of MSC was observed by inverted microscopy, the immunophenotypes of MSC were detected by flow cytometry, the proliferation ability of MSC was detected by using MTT method, the multi-differentation ability of MSC was assayed by osteogenic, lipogenic and chrondrogenic induction. The morphologic features, immunophenotypic characteristics, cell proliferation, and multipotential differentiation capability were compared between the MSC derived from normal healthy donors and AML patients. RESULTS: AML-MSCs presented the morphological features similar to the normal MSCs. In addition, AML-MSCs highly expressed CD29, CD44, CD73, CD105 and HLA-ABC. Meanwhile, they were homogenously negative for CD14，CD31, CD34, CD45, CD80, CD86 and HLA-DR. Further-more, AML-MSCs showed cell proliferation ability similar to normal MSCs. Notably, AML-MSCs exerted increased osteogenic-differentiation capacity as compared with normal MSCs. CONCLUSION AML-MSCs possess typical MSC phenotypes but displayed enhanced osteogenic-differentiation capacity.

OBJECTIVE: To explore the role of bone marrow microenvironment(niche) in the development of acute myeloid leukemia (AML) and the effect of AML patients-derived MSC on the proliferation, cell cycle and immuno-phenotypes of HL-60 cells. METHODS: The MSC derived from bone marrow of patients with newly diagnosed AML were isolated and co-cultured with HL-60 cells. The effect of MSC on proliferation of HL-60 cells was detected by using 3H-TdR incorporation method, the cell cycle and immunophenotypes of HL-60 cells were detected by flow cytometry. RESULTS: The results of 3H-TdR incorporation assay showed that both AML-MSCs and normal MSCs remarkably suppressed the HL-60 cell proliferation in a time- and dose-dependent manner. The results of cell cycle analysis demonstrated that AML MSCs and normal MSCs induced arrest of the HL-60 cells in G/G phase. The results of immunophenotyping revealed that MSCs suppressed the expression of CD11a and CD154 on the surface of HL-60 cells. Moreover, AML MSCs exhibited increased inhibitory effects than that of normal MSCs. However, no remarkable effect of MSCs on CD54 expressions of HL-60 cells was observed in the current study. CONCLUSION AML-MSCs possess effects on HL-60 cell proliferation, cell cycle and immunophenotypes similiar to normal MSCs, but exhibited increased suppressive capacity on the expression of CD11a and CD154.

Objective To investigate the expression of neural-nitric oxide synthase (nNOS) in renal clear cell carcinoma and its clinical significance.Methods The expression of nNOS mRNA in 533 samples of TCGA database was analyzed with Student t test,and statistical analysis was performed to assess the relationship between nNOS expression and clinical prognosis with Kapla-Meier test.Western blot analysis of nNOS protein expression in 10 cases of clear cell renal cell carcinoma(ccRCC) from department of urology of Wuhan union hospital with student t test.Results The mRNA levels of nNOS in 72 cases of ccRCC in tumor tissues and adjacent tissues and were 2.99 ± 0.28 and-1.57 ± 0.17,it is significantly lower than those in adjacent tissues (P ＜ 0.01).The mRNA levels of nNOS in 533 cases of ccRCC,in tumor tissues and adjacent tissues and were 2.99 ± 0.28 and-1.76 ± 0.05,it is significantly lower than those in adjacent tissues (P ＜ 0.01).A total of 533 sample studies showed a low correlation between nNOS expression and clinical T stage,T1-1.59 ±0.08,T2-1.96 ±0.13,T3-1.90 ±0.09,T4-2.38 ±0.28 (P =0.0029) and -1.63 ±0.06 and-2.16 ± 0.13 between non-metastasis and no-metastasis (P =0.0009),and-1.57 ± 0.08 and-2.03 ± 0.11 between non-recurrence and recurrence (P =0.008).Survival analysis showed that the overall survival time were (40.3 ± 5.6) months and (48.3 ± 5.7) months in lower and higher nNOS expression,and disease free survival time were (37.1 ± 2.1) months and (40.3 ± 5.6) months in lower and higher nNOS expression,both with shorter time in low expression of nNOS (P ＜ 0.01).nNOS proteins were 1.02 ± 0.16 and 0.61 ± 0.1 1 in tumor tissues and adjacent tissues with significantly lower expression(P＜0.05).Conclusions The mRNA and protein of nNOS are lower in ccRCC with a poor prognosis of ccRCC.

OBJECTIVETo investigate the efficacy of allogeneic hematopoietic stem cell transplantation（allo-HSCT）in the treatment of patients with Ⅲ,Ⅳ non-Hodgkin lymphoma（NHL）, and compared the efficacy between Cy- fractionated to talbody irradiation（fTBI）based conditioning regimen and Maryland, horse flange and mitoxantrone（BMM）.

METHODSThe clinical data of 47 patients with Ⅲ, Ⅳ NHL after allo- HSCT from November 1998 to May 2014 were collected and retrospectively analyzed. To observe the hematopoietic reconstruction recovery after transplantation, cumulative incidence of acute graft- versus- host- disease （aGVHD） and chronic graft- versus- host- disease （cGVHD）, transplantation related mortality （TRM）, recurrence rate （RR）, disease- free survival （DFS）, overall survival（OS）. Compare the efficacy of fTBI and BMM conditioning regimen at the same time.

RESULTSNeutrophils achieving 0.5×10⁹/L and platelets achieving 50×10⁹/L on day 17 （range, 10- 72） post transplantation. Acute GVHD occurred in 53.19%, among them, grade Ⅰ-Ⅱ occurred in 42.55%, grade Ⅲ-Ⅳ occurred in 10.65%, and cGVHD occurred in 21.28%. 21 patients were alive with a median follow up of 9.7 months（0.2-149.1 months）. Overall survival（OS）was 73.5%, 49.3%, 40.1% respectively in the first, third and fifth year in Cy-fTBI group; in BMM group it was 67.8%, 32.9% and 31.4% respectively, and disease-free survival（DFS）was 65.3%, 45.6%, 30.2% respectively in the first, third and fifth year. In Cy-fTBI group, the recurrence rate（RR）and transplantation related mortality（TRM）in the first year were 18.9%, 23.0% respectively, the third year were 19.5%, 38.3% and the fifth year were 35.2%, 39.2%. In BMM group, RR and TRM in the first year were 27.4%, 24.5% respectively, the third year were 38.9%, 46.4% and the fifth year were 39.2%, 48.2%. However, there was no significant difference in the indicator of OS, DFS, RR, TRM in the two groups.

CONCLUSIONAllo-HSCT could make some Ⅲ,Ⅳ NHL patients achieve long-term disease- free survival, but the TRM was still high relatively. Moreover, compared with the program of BMM conditioning regimen, Cy-fTBI might reduce the TRM and RR, meanwhile, increase the DFS and OS. However, due to the small number cases of two groups, there was no statistical significant difference.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.
