Objective To systematically evaluate the ICD coding data on the front page of inpatient medical records filed out by clinicians,and to analyze the quality of ICD codes reasonably,objectively and comprehensively by employing the 3×3 Da-ta Quality Assessment(3×3 DQA)model.Methods A total of 1 410 medical records from a tertiary women and children's hospital between June 2021 to July 2024 were randomly selected.Based on the 3×3 DQA model,the data quality of ICD codes for diagnosis and surgical procedures on the front pages filed out by clinicians was assessed.Results Among 1,410 medical re-cords reviewed,778 had defects,resulting in a total defect rate of 55.18％,including a completeness defect rate of 32.98％and an accuracy defect rate of 30.57％.Totally,a total of 9 302 ICD codes were reviewed,among which 1 254 had defects,with a total defect rate of 13.48％.The defect rates for the principal diagnosis,other diagnosis,principal operation,and other operation were 22.20％,17.72％,4.53％and 4.92％,respectively.For diagnostic ICD codes,the completeness defect rate was relative-ly high,while for surgical ICD codes,the accuracy defect rate was higher.In terms of specialties,there were statistically signifi-cant differences in the overall defect rates among gynecology,obstetrics,and pediatrics,with pediatrics and gynecology having defect rates higher than the overall average.Conclusion The quality of ICD code data on the front page of medical records filed out by clinicians is suboptimal,and there are differences in data quality across different specialties and ICD categories.There-fore,it is still necessary to conduct research on the supervision and improvement measures for ICD data quality in hospital medical record management.

OBJECTIVE：To systematically evaluate therapeutic efficacy of Gongliuqing capsules combined with mifepristone in the treatment of uterine leiomyoma ，in order to provide evidence-based reference for clinical medication. METHODS ：Retrieved from Cochrane Library ，PubMed，Embase，CJFD，VIP，CBM and Wanfang database ，randomized controlled trials （RCTs）about Gongliuqing capsules combined with mifepristone （trial group ）versus mifepristone alone （control group ）in the treatment of uterine leiomyoma were collected. After literature screening and data extraction ，the quality of included literatures was evaluated with modified Jadad scale. Meta-analysis was conducted by using Stata 14.0 software，and trial sequential analysis （TSA）was performed by using TSA 0.9 software. RESULTS ：A total of 12 RCTs were included ，involving 1 210 patients. The results of Meta- analysis showed that the total response rate of trial group [RR ＝1.12，95％CI（1.00，1.26），P＜0.05] was significantly higher than that of control group ；maximum uterine leiomyoma volume after treatment [SMD ＝－1.08，95％CI（－1.21，－0.95），P＜0.05]，uterine volume after treatment [SMD ＝－0.80，95％CI（－1.14，－0.45）， P＜0.05]，follicle stimulating hormone （FSH）level [SMD ＝ － 0.28，95％ CI（－ 0.45，－ 0.19），P＜0.05]，luteinizing hormone（LH）level [SMD ＝－0.44，95％CI（－0.52，－0.12）， 020-38076311。E-mail：867203217@qq.com P＜0.05]，E2 level [SMD ＝－2.69，95％CI（－3.08，－1.49）， P＜0.05] and progesterone （P）level [SMD ＝－1.27，95％CI（－1.69，－0.71），P＜0.05] of trial group were significantly lower or better than those of control group. Results of subgroup analysis showed that except for the level of FSH in 5 and 10 mg mifepristone groups （P＞0.05），maximum uterine leiomyoma volume after treatment ，uterine volume after treatment ，the levels of FSH，LH，E2 and P in trial group were significantly lower than control group. The results of TSA showed that there were definite evidences for total response rate of Gongliuqing capsules combined with mifepristone being better in the treatment of hysteromyoma. CONCLUSIONS ：Total response rate of Gongliuqing capsules combined with mifepristone in the treatment of hysteromyoma is better than mifepristone alone ，which can effectively decrease the volume of maximum uterine leiomyoma volume and uterine vilume ，and reduce the level of serum hormone.

Objective To explore the expression of anaplastic lymphoma kinase(ALK) in human ovarian serous adenocarcinoma cell line SKOV3 and to further investigate the effect of crizotinib on SKOV3 cells.Methods The expression of ALK in SKOV3 cells were examined by Western blotting and immunocytochemical methods,and the effect of ALK inhibitor crizotinib on proliferation of SKOV3 cells were evaluated by cell proliferation assay.Results Both Western blotting and immunocytochemical methods showed the expression of ALK in SKOV3 cells.The results of cell proliferation assay suggested that the cell viability of SKOV3 cells was close to 1 when the drug concentration was less than 106 nmol·L-1,and close to 64% when the drug concentration was up to 107nmol·L-1.Conclusion ALK is overexpressed in human ovarian serous adenocarcinoma cell line SKOV3,but SKOV3 cells were insensitive to the therapy of ALK inhibitor crizotinib.

The aim of this study is to investigate the growth and proliferation of bone marrow mesenchymal stem cells (BMSCs) three-dimensionally cultured in Pluronic F-127 gel, in order to explore the cellular compatibility of gel and to investigate the feasibility of BMSCs differentiating into adipocytes in gel. Rat BMSCs were isolated from adult bone marrow, and then cultured and amplified in vitro. The BMSCs derived from the 4th passage were seeded on the scaffolds and incubated in adipogenic stimuli culture to differentiate into adipocytes. BMSCs were dispersed into gel and cultured in vitro for two weeks then the status of adhesion, growth and proliferation of the cells were observed. The edipogenic differentiation of the BMSCs was assessed by cellular morphology and further confirmed by Oil Red O staining. BMSCs were able to attach, grow and proliferate well in Pluronic F-127 gel. The BMSCs differentiated into adipocytes in gel in the presence of adipogenic stimuli over a period of 2 weeks. After only 4 days of adipogenic induction, small lipid droplets were observed within BMSCs in gel wells treated with differentiation media. At the end of 14 days, in the presence of differentiation media in gel, the size of the lipid droplets increased to occupy most of the cytoplasm, consistent with differentiation of BMSCs into adipocytes. Lipid droplets in differentiating BMSCs were positively stained with Oil Red O in the presence of differentiation media in the Pluronic F-127 treatment. We demostrated BMSCs incubated in the 3D Pluronic F-127 gel scaffolds could be induced and differentiated into adipocytes. The system for inducing differentiation of BMSCs into adipocytes is promising to apply in the construction of tissue engineering adipose tissue and the repair of fat injury, and Pluronic F-127 gel may be a suitable scaffold for cellular therapy of BMSCs.
