Background and purpose:Endometrial carcinoma is a common malignant tumour in women and expresses COX-2,CDK4;the expressions are associated with the development of the tumour. Mifepristone can inhibit the growth of the tumours, but its mechanisms are not very clear, We investigated the inhibitory effect of antiprogestins mifepristone n the growth of human endometrial carcinoma cell line HHUA xenografted in nude mice of and the expressions of COX-2,CDK4,the purpose was to find out whether or not mifepristone could influence the expressions of COX-2,CDK4. Methods:Human endometrial carcinoma HHUA cells were cultured in vitro.The models of xenografted tumor were established by the transplantation of human endometrial carcinoma HHUA cell on nude mice. The nude mice were randomly divided into two groups to receive either refined peanut oil (control group), or daily mifepristone for six weeks, respectively . The sizes of xenograft were measured in the pre-and post-treatment. The changes of morphology were observed by glass microscopy. The positive immunostaining for COX-2 and CDK4 were evaluated semiquantitatively by using an immunohistochemical scoring system (HSCORE) that it incorporated both the intensity and the distribution of specific staining.Results:After 6 weeks of treatment , the size of the xenografts in MIF group were 115.25?10.97 mm 3 ,compared with 313.25?43.92 mm 3 in the control group (P

Objective To investigate the clinical characteristics and treatment efficacy in newly diagnosed multiple myeloma (MM). Methods The clinical data and treatment methods of 176 patients with newly diagnosed MM were retrospectively analyzed. Results The most common chief complaint in the patients with MM was bone pain. 26.1 % (46/176) patients once experienced misdiagnosis. The overall response rate (ORR) was 65.9 % (116/176), the ORR of bortezomib group (81.0 %, 34/42) was significantly higher than that of M2 regimen group (61.8 %, 34/55) and VAD regimen group (60.8 %, 48/79) (P<0.05). Between normal renal function subgroup and renal insufficiency subgroup in bortezomib group, the efficacy was no significant difference (P>0.05). The most common adverse reactions included hematologic toxicity, infection and peripheral neurotoxicity. Multiple organ failure was the main cause of death (47.1 %, 16/34). Conclusions The clinical manifestations of MM are complex and diverse, which is easy to be misdiagnosed. Molecular genetic abnormalities are closely related to prognosis. Proteasome inhibitor bortezomib can improve the curative effect and not be affected by renal function. To prolong the survival time of the patients needs to prevent and control the infection and renal insufficiency actively.

Objective To investigate the efficacy and safety of a schedule of 2 cycles' high-dose dexamethasone (HD-DXM) as an initial therapy in adults immune thrombocytopenia (ITP), and compare with conventional dose prednisone therapy. Method A total of 59 newly diagnosed ITP patients were divided into 2 groups randomly. In 30 patients ( Dexamethasone group), oral HD-DXM was administered at 40 mg/d for 4 consecutive days, repeated one week later, and then failed to maintain. In the remaining 29and then gradually tapered. Results For short-term efficacy, after 1 and 2 weeks of treatment, the response rate in Dexamethasone group was significantly higher than that in Prednisone group (50. 0% vs 24. 1%, P <0. 01; 73.3% vs 55.2%, P <0. 05 ), while 3 weeks later, there was no remarkable difference between the two groups(83.3% vs 68.9%, P > 0. 05 ), though the response rate in Dexamethasone group remained higher. For long-term effect, at the end of the 2nd and 3rd months of follow-up, the relapse rate in Dexamethasone group was significantly lower than that in Prednisone group(24. 0% vs 40. 0%, P < 0. 05;32.0% vs 65. 0%, P < 0. 01 ), while at the end of the 1st month of follow-up, there was no significant difference( 16. 0% vs 20. 0%, P >0.05 ). In addition, it's well tolerated and no complications such as severe infection or Cushing syndrome were complained in Dexamethasone group. Conclusion HD-DXM possesses an advantage over conventional dose prednisone therapy in efficacy and safety.

Objective:To investigate the clinical characteristics and prognosis of Philadelphia (Ph) chromosome-positive chronic myeloid leukemia (CML) patients with additional chromosomal abnormalities.Methods:The data of 351 CML patients with Ph-positive in the Affiliated Hospital of Qingdao University from January 2009 to January 2019 were retrospectively analyzed. The bone marrow chromosomal karyotype analysis of all patients was performed by using R-banding technique. The clinical characteristics and karyotype of Ph-positive CML patients with additional chromosomal abnormalities at initial diagnosis were summarized, and Kaplan-Meier was used to analyze the differences in overall survival (OS) of patients with different karyotypes.Results:Among 351 patients with Ph-positive CML, 32 (9.1%) cases had variant translocation. At initial diagnosis, 47 cases had additional chromosomal abnormalities including 29 cases in chronic phase accounting for 9.15% (29/317) of all patients in chronic phase, 3 cases in accelerated phase accounting for 25.00% (3/12) of all patients in accelerated phase, 15 cases in blast crisis accounting for 68.18% (15/22) of all patients in blast crisis; there was a statistically significant difference in the chromosomal abnormalities rate of all different phases ( χ2=50.799, P<0.05). Among 47 Ph-positive CML patients with additional chromosomal abnormalities, 13 patients had complex karyotypes with more than 3 additional chromosomal abnormalities, the proportion of complex karyotypes in chronic phase, accelerated phase and blast crisis was 13.79% (4/29), 33.33% (1/3) and 53.33% (8/15), respectively, and the difference was statistically significant ( χ2=9.26, P<0.05). The study showed that the most common additional chromosomal abnormalities in chronic phase were double Ph (48.28%, 14/29) and -Y (10.34%, 3/29), while the most common chromosomal abnormalities in the blast crisis were +8 (26.67%, 4/15) and double Ph (26.67%, 4/15). Kaplan-Meier survival analysis showed that at initial diagnosis the OS time of patients with additional chromosomal abnormalities was worse than that of those with the non-additional chromosomal abnormalities group ( χ2 = 61.138, P<0.05). The OS of patients with complex karyotypes for Ph - positive CML patients with additional chromosomal abnormalities at initial diagnosis was worse than that of patients with non-complex karyotypes, and the difference was significant ( χ2 = 4.945, P < 0.05). Conclusions:The additional chromosomal abnormalities is closely related to the progression of CML, and the prognosis of CML patients with additional chromosomal abnormalities is poorer than that of patients with only Ph translocation. Moreover, the more complex the additional chromosomes are, the more likely blastic changes are, and the poorer prognosis. And additional chromosomeal abnormalities during the treatment of CML patients may also lead to the progression of blastic changes.

Objective:
To evaluate the effect of Tai Chi and Qigong on patients with lumbar disc herniation (LDH).
Methods:
Relevant data were retrieved from nine English and Chinese databases, including Cochrane Library, PubMed, and Wanfang Data, etc. from inception to June 2024. All published randomized controlled trials assessing the effect of Tai Chi and Qigong on visual analog scale (VAS), Japanese Orthopedic Association (JOA) score, and other health indicators in participants with LDH compared to usual medical care or other treatments were included. Grey literature, trials involving the pushing of hands (Tui Shou) or Tai Chi with weapons, and trials with co-interventions (Tai Chi/Qigong plus another treatment) were excluded. Methodological quality was analyzed using the Cochrane risk of bias tool, and evidence quality was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool.
Results:
Fourteen trials (954 patients) were included in this study. Tai Chi and Qigong were associated with lower VAS pain scores (standardized mean difference −0.55, 95% confidence interval [CI] −0.95 to −0.15, P = .01), higher JOA scores (mean difference [MD] 4.40, 95% CI 2.62 to 6.18, P < .001) and straight leg raise test results (MD 9.40°, 95% CI 7.64 to 11.15, P < .001) in patients with LDH. Furthermore, compared with usual care, Tai Chi and Qigong showed enhanced effects on pain and JOA scores. When compared to other exercises or massage, the effect on pain scores was similar but that on JOA scores was significant.
Conclusions
Tai Chi and Qigong may have favorable effects on VAS pain and JOA scores compared with usual care, and on JOA scores compared with other exercises or massage in patients with LDH. Given the overall poor quality of the evidence, the results of current study should be interpreted cautiously.

OBJECTIVETo study the relationship between the expression of soluble drug resistance-related calcium-binding protein (sorcin) gene and the clinical multidrug resistance in acute leukemia (AL).
METHODSA semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) was used to investigate the transcription levels of the human sorcin gene in 95 AL patients and 27 controls.
RESULTSSorcin gene expression was significantly higher in AL patients than in normal contrls (P < 0.001), and higher in relapsed/refractory acute myeloid leukemia (AML) patients than in those newly diagnosed or in complete remission. Sorcin gene overexpression was significantly lower in non-resistant patients than in resistant ones (P < 0.001). CR rates of these two groups were 20.0% and 80.0%, respectively. Sorcin gene expression was higher in AML-M(5) patients than M(2), M(3), M(4) patients.
CONCLUSIONSorcin gene overexpression is significantly associated with clinical multidrug resistance and prognosis, it is one of the indicators for predicting prognosis of AL patients.
