[Clinical outcomes analysis of fertility-preserving therapy for atypical endometrial hyperplasia and early endometrial carcinoma].

Objective: To analyze the clinical efficacy of fertility-preserving therapy in patients with atypical endometrial hyperplasia (AEH) and early endometrial carcinoma (EC). Methods: The general condition, pathological type, treatment plan, tumor outcomes and pregnancy outcomes of 110 patients with AEH and EC treated with fertility-preserving therapy in Peking University People's Hospital from December 2005 to September 2019 were retrospectively analyzed. Kaplan-Meier and Log rank tests were used for survival analysis. Results: The response rate of 110 cases of AEH (62 cases) and EC (48 cases) was 94.5% (104/110) after fertility-preserving therapy. There were 93 cases (84.5%) achieved complete response and 11 cases (10.0%) achieved partial response, and the recurrence rate was 29.0% (27/93). The complete response rates of AEH and EC were 90.3% (56/62) and 77.1% (37/48), respectively, without significant difference (P=0.057). The recurrence rates of EC were significantly higher than that of AEH (40.5% vs 21.4%; P=0.022). Forty-one patients with complete response had pregnancy intention, the pregnancy rate was 70.7% (29/41), and the live birth rate was 56.1% (23/41). The live birth rate of AEH was 68.2% (15/22) and that of EC was 42.1% (8/19), the difference was statistically significant (P=0.032). The pathological type was related with the recurrence (P=0.044). Conclusions: Patients with AEH and EC can obtain high complete response rate and pregnancy rate after fertility-preserving therapy. The recurrence rate of EC is higher than that of AEH, while the live birth rate of AEH is higher than that of EC.

[Preliminary study on the expression of MIF in HCC tissues and its relationship with ERK1/2 signaling pathway].

Objective: To investigate the expression of Macrophage migration-inhibitory factors (MIF) in hepatocellular carcinoma (HCC) tissues and its interaction with ERK1/2 signaling pathway, so as to establish a theoretical basis for further studying the molecular mechanism of MIF promoting HCC. Methods: From February 2020 to August 2021, 52 cases of hepatocellular carcinoma (HCC) tissues based on hepatitis B cirrhosis (HBV-LC) and 52 cases of adjacent tissues in Tianjin Medical University Cancer Hospital and 940th Hospital of Joint Logistic Support Force of PLA were collected as the experimental group, including 39 males and 13 females, aged 35-65 years. And 20 cases of normal liver tissue were selected as the control group. Immunohistochemistry was used to detect the expression of MIF, ERK1/2 and p-ERK1/2 proteins in liver tissues of the two groups, and in situ hybridization was used to detect the expression of ERK1/2 nucleic acid in liver tissues of the two groups.HepG2 HCC cells and L-02 normal hepatocytes were co-cultured with different concentrations of rMIF, the expression and phosphorylation levels of ERK1/2 and JNK1 proteins in the two kinds of liver cells were detected by Western-blot, and the expression levels of ERK1/2 nucleic acids in the two kinds of liver cells were detected by RT-PCR. One-way ANOVA was used for measurement data and χ2 test was used for counting data. Results: The expressions of MIF, ERK1/2, p-ERK1/2 and ERK1/2 mRNA were significantly increased in HCC and para-cancer tissues (the expression of MIF in HCC group was 78.8%, and that in adjacent group was 75.0%; ERK1/2 80.8% in HCC group and ERK1/2 71.8% in paracancerous group. The expression of p-ERK1/2 75.0 % in HCC group and 46.2% in paracancerous group were respectively detected. ERK1/2 mRNA was expressed in HCC group 76.9%, ERK1/2 mRNA expression in paracancerous group 78.8%), and the differences were statistically significant compared with normal liver tissues (P<0.05), but there was no significant difference between HCC and para-cancer tissues (P>0.05). The expressions of ERK1/2, p-ERK1/2 and ERK1/2 mRNA in HepG2 HCC cells were significantly increased with the increase of rMIF concentration, and the increase was most obvious when rMIF concentration was 200 ng/ml, and the difference was statistically significant compared with L-02 normal hepatocytes (P<0.05). Conclusion: MIF, ERK1/2 and p-ERK1/2 are highly expressed in HCC tissues and HepG2 HCC cells, suggesting that MIF promotes the occurrence and development of hepatocellular carcinoma through ERK1/2 signaling pathway.

[Occurrence and recovery of adverse drug reactions of preventive treatment in elderly population with latent tuberculosis infection].

Objective: To evaluate the occurrence and recovery of adverse drug reactions (ADRs) of preventive treatment in the elderly population with latent tuberculosis infection (LTBI). Methods: A total of 2 583 elderly patients with LTBI were recruited in Zhongmu, Henan Province from July 1 to October 17, 2015. Face-to-face surveys and physical examinations were used to obtain the basic information of the participants, and the body mass index (BMI) was calculated. Fasting venous blood was collected from the participants for blood biochemical and routine blood tests. The random numbers were generated by Excel 2010, and the participants were divided into group A (1 284 cases) and group B (1 299 cases) by simple randomization. Both group A and group B received combination treatment of isoniazid and rifapentine. Group A was treated for 8 weeks with weekly doses of isoniazid at 15 mg/kg and 900 mg for those with body weight ≤50 and>50 kg, respectively, and the doses of rifapentin were 750 and 900 mg, respectively. Group B was treated twice a week for 6 weeks, the doses of isoniazid in patients with body weight ≤50 and>50 kg were [600-(50-body weight)×15] (rounded up) and 600 mg, respectively, and the doses of rifapentin were 600 and 450 mg, respectively. During the treatment period, doctors observed, inquired about and recorded symptoms related to ADRs, and blood biochemical and routine blood tests were performed at 4 weeks after taking the drug, the end of the treatment, and 3 months after the end of the treatment. The patients with ADRs were treated accordingly by severity. The ADRs and graded treatment outcomes of LTBI patients in group A and group B were compared. Results: The ageï¼»M（Q1，Q3）］of the participants was 60 (55,65) years old, and 54.7% (1 412/2 583) were males. There were no statistical differences in age, gender, BMI and baseline biochemical indexes between groups A and B (all P values>0.05). The incidence of ADRs in group A and group B were 18.5% (237/1 279) and 16.3% (209/1 279), respectively, and those with alanine aminotransferase (ALT)≥5 ULN accounted for 0.8% (7/931) and 1.1% (11/987), aspartate aminotransferase (AST)≥5 ULN accounted for 0.3% (3/931) and 0.3% (3/987), respectively, and there were no statistically significant differences (all P values>0.05). There were 7 and 11 patients with ALT≥5 ULN in group A and group B, respectively, and 3 patients with AST≥5 ULN for each group, respectively. After treatment, except for 2 patients with ALT≥5 ULN in group B, ALT and AST levels in all the other patients returned to normal. There were 15 and 10 patients with abnormal white blood cell count in group A and group B, respectively, and 10 and 9 patients returned to normal after treatment. Conclusion: LTBI preventive treatment has a high incidence of adverse drug reactions, but it can be effectively controlled through active monitoring and graded management.

[Analysis of the epidemiological characteristics and genetic characteristics of influenza in the surveillance-year of 2021 to 2022 in Shandong Province, China].

Objective: To analyze the epidemiological characteristics, etiology and hemagglutinin (HA) gene characteristics of prevalent strains in Shandong Province from 2021 to 2022. Methods: The sentinel surveillance data of influenza-like illness (ILI) were collected in Shandong Province from 2021 to 2022. ILI specimens were detected with Real-Time PCR and virus isolation to explore the distribution of influenza viruses in different months. Three virus strains of each city were selected for gene sequencing, and the HA phylogenetic analysis was carried out. Results: In the surveillance-year from 2021 to 2022, 528 263 ILI cases were totally reported in 54 sentinel hospitals for influenza surveillance in Shandong Province. ILI visiting ratio (ILI%) was 4.07%, with the largest number in 0-4 age group (45.86%). The highly frequent season for ILI was in winter and spring, with a peak in the 52nd week, 2021 (6.62%). Totally, nucleic acid was detected in 26 754 specimens, with a positive rate of 27.10%, all of which were type B Victoria influenza. The positive rate reached a peak in the 49th week, 2021 (63.78%). A total of 295 outbreaks of ILI had been reported, in which 269 were positive for influenza virus. Most of outbreaks occurred in the primary school, with a peak in December. Gene evolution analysis showed that the HA gene in Shandong possessed high homology, 98.6% to 99.5%, with the recommended vaccine strains in 2020-2023, which was divided into two branches, V1A.3a.1 and V1A.3a.2. Conclusion: In the surveillance-year of 2021-2022, influenza is prevalent in December in Shandong Province, with a single circulating strain type. The positive rate of influenza virus and outbreak are higher than those in the previous surveillance-year. The circulating strain possesses high HA gene homology with those of the WHO vaccine recommended strains. However, the overall immune barrier of influenza virus is weak.

[Research progress on the relationship between liver cirrhosis and thyroid hormones].

There exists a complex relationship between liver and thyroid hormones. Liver plays an important role in the activation, inactivation, transportation, and metabolism of thyroid hormones. At the same time, thyroid hormones also affect hepatocytes activity and liver metabolism, such as lipid and bilirubin metabolism. Importantly, thyroid hormone levels often change abnormally in patients with liver cirrhosis. Therefore, studying the change of thyroid hormone levels in patients with liver cirrhosis has a certain clinical value for assessing the severity, prognosis, diagnosis and treatment. This paper reviews the research progress on the relationship between liver cirrhosis and thyroid hormone.

[Primary orbital leiomyosarcoma: a case report].

A 20-year-old girl came to the Tianjin Medical University Eye Hospital because of progressive herniation of her right eye for 3 months. Examination revealed a huge mass behind the right eyeball, which was clinically diagnosed as a space-occupying lesion of the right orbit. Because the tumor was close to the nerve, most of the tumor was resected and pathologically diagnosed as a poorly differentiated leiomyosarcoma. Orbital evisceration was performed later. There was no recurrence during the 10-year follow-up.

[Screening of differently expressed miRNAs and the mechanism of miR-3907 in meibomian gland carcinoma].

Objective: To screen the differently expressed microRNAs (miRNAs) and to explore the effect and mechanism of microRNA-3907 (miR-3907) in meibomian gland carcinoma (MGC). Methods: Experimental research. MGC tissues and para-carcinoma tissues of patients diagnosed with MGC by histopathology were collected from July 2011 to January 2019 in Tianjin Medical University Eye Hospital. The miRNA microarray analysis of MGC and para-carcinoma tissue samples from 5 patients was performed. miR-3907 with a significant up-regulation was selected as a research object. Bioinformatics predicted and dual-luciferase gene reporter assay verified miR-3907 target genes. The protein expression levels of target genes in 18 MGC tissues and 6 para-carcinoma tissue samples were determined by immunohistochemical staining. miR-3907 over-expression, miR-3907 knock-down, target gene knock-down and miR-3907 knock-down with target gene knock-down were respectively performed in MGC cell. The mRNA and protein expressions were validated by real-time PCR and Western blotting after transfection. The cell proliferation and migration ability was detected by cell counting kit-8 and scratch experiment after transfection. The main statistical methods were Fisher's exact test, independent sample t test, two-factor repeated measure analysis of variance. Results: There were 22 differently up-regulated miRNAs and 5 differently down-regulated miRNAs in MGC tissues, of which miR-3907 was significantly up-regulated. Thrombospondin-1 (THBS1) was a target gene of miR-3907 according to bioinformatics and dual-luciferase gene reporter assay. The positive expression rate of THBS1 protein in para-carcinoma tissues (6/6) was significantly higher than that in MGC tissues (5/18), and the difference was statistically significant (P=0.003). Compared with the negative control group, the proliferation ability of the miR-3907 over-expression group was increased at 48 h and 72 h (F=3.70, 2.65; both P<0.01), and the migration rate at 24 h was significantly higher (54.6%±3.4% vs. 34.2%±0.6%; t=8.34, P<0.01). Compared with the negative control group, the proliferation ability of the miR-3907 knock-down group was decreased at 24 h, 48 h and 72 h (F=3.10, 2.17, 3.09; all P<0.05), and the migration rate at 24 h was significantly lower (40.8%±2.8% vs. 69.7%±2.7%; t=10.42, P<0.01). Compared with the negative control group, the THBS1 knock-down group promoted cell proliferation at 24 h, 48 h and 72 h (F=3.84, 3.79, 2.24; all P<0.05), and the migration rate at 24 h was significantly increased (82.5%±1.9% vs. 37.6%±5.1%; t=11.74, P<0.01). Compared with the control group, the miR-3907 knock-down with THBS1 knock-down group increased proliferation at 24 h and 48 h (F=3.97, 3.31; both P<0.05), and the migration healing rate at 24 h was significantly increased (56.9%±2.2% vs. 41.9%±4.3%; t=3.53, P<0.05). Conclusions: There are differently expressed miRNAs between MGC and para-carcinoma tissues, which may be related to the occurrence and development of MGC. miR-3907 in MGC tissues has a significant difference from that in para-carcinoma tissues. Moreover, miR-3907 can play a role in promoting proliferation and migration of MGC by inhibiting the expression of THBS1.

[Clinical and imaging characteristics of patients with different types of infectious sacroiliitis].

To investigate the clinical manifestations and imaging characteristics of patients with different types of infectious sacroiliitis. Clinical data of 40 patients diagnosed with infectious sacroiliitis were retrospectively analyzed. Among the 40 patients, 16 patients were diagnosed as non-brucellar and non-tuberculous infectious sacroiliitis (ISI), 13 with tuberculous infectious sacroiliitis (TSI), and 11 with brucellar sacroiliitis (BSI). In the ISI and TSI group, female patients accounted for 11/16, 12/13, while the proportion of unilateral involvement was 15/16 and 12/13, respectively. Compared with ISI and TSI group, BSI patients were mainly male (8/11) and presented more bilateral involvement (6/11) (P<0.05). Bone erosion was more common in ISI and TSI groups than in BSI group (6/15, 7/11 and 2/10), as well as abscess formation (3/15, 4/11 and 1/10, respectively). Symptoms in all patients relieved 1-2 weeks after administration of antibiotics or anti-tuberculosis treatment, but the resolution of the magnetic resonance imaging findings delayed about 6 (3-9) months. ISI and TSI patients with infectious sacroiliitis should be differentiated from spondyloarthritis, with a characteristic of more female patients, unilateral sacroiliitis, bone erosion, soft tissue involvement and abscess formation. However, BSI patients are mainly male, more bilateral involvement and less bone destruction and abscess formation. Antibiotic therapy demonstrates significant therapeutic effects, but resolution of the magnetic resonance imaging findings responses late.

[Effect of axillary lymph node status on prognosis of different types of invasive breast cancer].

Objective: To investigate the effect of axillary lymph node status on the prognosis of different types of invasive breast cancer. Methods: Patients with invasive breast cancer of different molecular subtypes diagnosed in the breast cancer prevention and treatment center of Beijing Cancer Hospital from January 2000 to July 2011 were collected as a historical cohort, and the influence of lymph node status on the prognosis of different types of breast cancer was analyzed. Results: A total of 4 269 female breast cancer patients with molecular subtypes [aged (50.8±11.2) years] information and 3 824 female breast cancer patients with complete axillary lymph node status information [aged (50.5±10.9) years] were included in the study, including 3 135 cases with both molecular subtypes and lymph node status information. The 10-year event free survival (EFS) rates of hormone receptor (HR)+/human epidermal growth factor receptor-2(HER2)-, HR-/HER2-and HER2+were 82.2%, 79.0% and 76.8%, respectively; the 10-year overall survival (OS) rates were 88.1%, 83.1% and 84.4%, respectively, and the differences of 3 molecular subtypes in EFS and OS were statistically significant (both P<0.001). The 10-year EFS rate of lymph node positive and negative patients was 68.8% and 88.2%, respectively; the 10-year OS rate was 76.7% and 92.5%, respectively, and the differences of lymph node status in EFS and OS were statistically significant (both P<0.001). In lymph node negative subgroup, 3 subtypes showed similar EFS and OS rate (both P>0.05); In lymph node positive subgroup, 3 subtypes showed significantly different EFS and OS (both P<0.05). No modification effect was detected of lymph node status on the correlation of molecular subtypes and EFS, DDFS and OS(all Pinteractive>0.1). Conclusions: Different molecular subtypes of breast cancer have different prognosis. Compared with molecular subtype, lymph node status may be a more important prognostic factor.

[Clinical observation of combined oral contraceptives drospirenone and ethinylestradiol tablets (â ¡) in the treatment of dysmenorrhea in Chinese women].

Objective: To evaluate the efficacy and safety of drospirenone and ethinylestradiol tablets (Ⅱ) in Chinese women with dysmenorrhea. Methods: This was a single-arm, open-label, interventional, multicenter, post-authorization safety/effectiveness study of drospirenone and ethinylestradiol tablets (Ⅱ) across 6 treatment cycles, a total of 526 patients were included in the dysmenorrhea subgroup. Visual analog scale (VAS) was used to assess the severity of menstrual pain. Secondary outcomes included unintended pregnancies, bleeding pattern, cycle control and safety. Results: After treated with drospirenone and ethinylestradiol tablets (Ⅱ), VAS of pain had decreased significantly compared with baselines [(49.5±23.7) vs (32.3±24.9) vs (20.7±19.4) vs (18.4±18.7) mm, P<0.01]. From the second cycle to the fifth cycle, the incidence of scheduled bleeding increased from 93.9% (450/479) to 96.4% (431/447). The duration of scheduled bleeding decreased from (5.7±2.7) to (5.4±1.8) days. The incidence of intermenstrual bleeding decreased from 9.0% (43/479) to 5.6% (25/447). 17.5% (92/526) patients reported adverse drug reactions, most frequently reported adverse events were breast pain, nausea, breast swelling, headache, and uterine bleeding. No death occurred during the study. Conclusion: Drospirenone and ethinylestradiol tablets (Ⅱ) is effective for the treatment of dysmenorrhea and has good safety.

[Long-term recurrence rate and survival in different aged patients with breast cancer undergoing breast conserving therapy].

Objective: To examine the difference of long-term recurrence rate and survivals between the young patients and the old patients undergoing breast conserving therapy (BCT). Methods: Women with primary invasive breast cancer receiving BCT between December 1999 and December 2014 were selected retrospectively from the database of Breast Cancer Center, Peking University Cancer Hospital & Institute. The median age of all patients was 47 years (range: 21 to 91 years). The cases were categorized according to age at diagnosis into two subgroups: the ≤40 years group and the>40 years group. A total of 2 778 patients were included: 677 patients in the ≤40 years group and 2 101 patients in the >40 years group. Clinicopathological characteristics between two groups were compared. The recurrence rate and survival were calculated using the Kaplan-Meier method. The differences of outcomes were compared in different aged groups using the Log-rank test. Factors affecting local recurrence, distant disease-free survival (DDFS), disease-free survival (DFS), and breast cancer-specific survival (BCSS) were assessed by multivariable Cox proportional hazard models. Results: Proportions of T1 (301/677 vs. 1 160/2 101, χ²=37.660, P<0.01), involved lymph node (314/677 vs. 713/2 101, χ²=34.966, P<0.01) hormone receptor-negative (490/677 vs. 1 581/2 101, χ²=6.981, P=0.030) and neoadjuvant chemotherapy (413/677 vs. 1 010/2 101, χ²=34.272,P<0.01)in the ≤40 years group were higher than that in the>40 years group. Median follow-up duration was 102 months. No significant difference in 10-year local recurrence was found between the two groups (2.5% vs. 1.6%, P=0.147). Ten-year DDFS rate in the ≤40 years group and in the>40 years group was 90.6% and 95.3%, respectively (P<0.01). Ten-year DFS rate in the ≤40 years group and in the>40 years group was 86.5% and 91.1%, respectively (P=0.001). Ten-year BCSS rate in the ≤40 years group and in the >40 years group was 91.0% and 93.7%, respectively (P=0.105). Age was not the prognosis factor of local recurrence. Lymph node status (positive vs. negative: HR=2.73, 95%CI: 1.94 to 3.84, P<0.01), age (≤40 years vs.>40 years: HR=1.73, 95%CI: 1.24 to 2.42, P=0.001) and T stage (>2 cm vs. ≤2 cm: HR=1.61, 95%CI: 1.14 to 2.28, P=0.001) were the prognosis factors of DDFS, and also for DFS. Hormone receptor status (positive vs. negative: HR=0.54, 95%CI: 0.39 to 0.74, P<0.01), lymph node status (positive vs. negative: HR=2.94, 95%CI: 2.12 to 4.07, P<0.01) and T stage (>2 cm vs. ≤2 cm: HR=1.45, 95%CI: 1.05 to 2.01, P=0.025) were the prognosis factors of BCSS. Conclusions: The risk of local recurrence was similar between ≤40 years patient and >40 years patients receiving breast conserving therapy. Worse survivals in the ≤40 years group were found comparing to those in the >40 years group.

[Proteomic analysis of lacrimal gland adenoid cystic carcinoma with high-grade transformation].

Objective: To analyze the protein expression differences of lacrimal gland adenoid cystic carcinoma (LACC) with high-grade transformation (HGT). Methods: Experimental study. A total of 8 paraffin tissue samples were collected in Tianjin Medical University Eye Hospital from December 2012 to January 2019. According to pathological examination, the samples were divided into the LACC group and the LACC-HGT group, with 4 cases in each group. The LACC group included 2 male samples and 2 female samples, with an average age of 53 years. The LACC-HGT group included 2 male samples and 2 female samples, with an average age of 44 years. Primary cells were cultured from fresh tumor tissue. Isobaric tags for relative and absolute quantification techniques were used to screen the differentially expressed proteins between the two groups, and bioinformatics analysis was conducted for the differentially expressed proteins. Microarray was used to screen differentially expressed mRNAs between LACC and LACC-HGT primary cells. The mass spectrum data were intersected with mRNA microarray data, and quantitative real-time (qRT) PCR was performed to verify the results. Proteomics and microarray data were compared using the independent sample t test. The qRT-PCR data were compared pairwise by one-way analysis of variance. Results: A total of 105 HGT-related differential proteins were detected in this study, including 50 up-regulated proteins and 55 down-regulated proteins. The significantly up-regulated proteins included hemoglobin subunit beta, hemoglobin subunit alpha 1, and collagen type Ⅵ alpha 2 chain; the significantly down-regulated proteins included Cereblon, adenosylhomocysteinase like 2, and ribosomal protein L39 pseudogene 5. Gene ontology analysis results showed that the LACC-HGT differential proteins were mainly located in the cytoplasm, vesicle cavity, and extracellular matrix, had organic acid binding and molecular carrier activity, and participated in the regulation of extracellular matrix composition, immunity, inflammation, apoptosis, and other biological processes. Pathway analysis showed that the LACC-HGT differential proteins were mainly involved in signal pathways such as mitogen-activated protein kinase signal pathway and extracellular matrix proteoglycans and glycan metabolism signal pathway. Protein complex prediction analysis screened out 4 up-regulated protein complexes and 1 down-regulated protein complex. There were 15 LACC-HGT differential proteins that overlapped with mRNA chip differential genes, of which 6 were tumor-related proteins including collagen type XIV alpha 1 chain (COL14A1), EMAP like 4 (EML4), inter-alpha-trypsin inhibitor heavy chain 4 (ITIH4), NDRG family member 2 (NDRG2), osteoglycin (OGN) an Ras homolog family member C (RhoC). The main function was the movement and migration of tumor cells. The qRT-PCR results showed that the relative expression levels of COL14A1, EML4, ITIH4, NDRG2, OGN, and RhoC in primary LACC-1, LACC-2, LACC-HGT-1, and LACC-HGT-2 cells were significantly different (F=1 675.98, 38.53, 27.37, 16.47, 13.38, 25.22, all P<0.01). For example, the relative expression of COL14A1 in primary LACC-HGT-1 (16.09±0.51) and LACC-HGT-2 (9.96±0.34) cells was significantly higher than that in primary LACC-1 (1.00±0.13) and LACC-2 (0.67±0.08) cells (all P<0.05). Conclusion: There are differentially expressed proteins between LACC-HGT and LACC, among which COL14A1, EML4, ITIH4, NDRG2, OGN, and RhoC may play an important role in LACC-HGT and can be used as potential targets of LACC-HGT in further study.

[Safety and short-term efficacy analysis of breast-conserving surgery combined with intraoperative radiotherapy for early-stage breast cancer].

Objective: To analyze the safety and short-term efficacy of breast-conserving surgery combined with intraoperative radiotherapy for early-stage breast cancer. Methods: A total of 101 consecutive patients who received breast-conserving surgery plus intraoperative radiotherapy were recruited to summarize the recent follow-up results and clinicopathological data. Univariate analysis and Logistic regression model were used to evaluate the factors affecting the postoperative adverse reactions and cosmetic effects. Results: Among 101 patients, 4 patients had recurrence or metastasis. The 3-years disease free survival rate was 94.9%, and the 3-years cumulative recurrence rate was 5.1%. Univariate analysis showed that the menstrual status and postoperative whole breast radiotherapy were associated with the postoperative adverse reactions (P<0.05). The T stage and applicator diameter were associated with the cosmetic effect (P<0.05). Multivariate analysis indicated that the diameter of the applicator (OR=3.701, P=0.026) and postoperative whole breast radiotherapy (OR=5.962, P=0.005) were independent factors for the postoperative adverse reactions, and the diameter of the applicator (OR=2.522, P=0.037) was an independent factor for the cosmetic effect. Conclusion: Breast-conserving surgery combined with intraoperative radiotherapy shows safety and good short-term efficacy in low-risk early-stage breast cancer.

[Clinical efficacy and pregnancy outcomes of fertility-preserving re-treatment after recurrence of the patient with atypical endometrial hyperplasia and early stage endometrial carcinoma].

Objective: To analyze the clinical efficacy and pregnancy outcomes of fertility- preserving re-treatment in patients with recurrent atypical endometrial hyperplasia (AEH) and early stage endometrial carcinoma (EEC) after achieved complete remission (CR) of primary fertility-preserving therapy. Methods: There were 104 cases of AEH and EEC collected from 9 hospitals in the multi-center research network platform of fertility-preserving therapy of endometrial carcinoma in China from January 2005 to May 2019. Thirth-one cases of them relapsed from four hospitals mentioned above,who achieved CR after primary fertility-preserving therapy,was analyzed retrospectively. Of the 31 cases, 27 cases chose fertility-preserving re-treatment. The demographic characteristics, re-treatment effect, clinical factors and pregnancy outcomes were observed. Results: (1) There were 16 AEH cases and 11 ECC cases among 27 recurrent patients who chose fertility-preserving therapy again. After re-treatment, CR was found in 13 out of 16 cases of AEH and 9 out of 11 cases of EEC. The overall CR rate was 81% (22/27). (2) After CR of recurrence, 5 cases (23%, 5/22) of re-recurrence were found after with a median time of 33 months (range 21-80 months). There were 4 cases underwent comprehensive surgical staging, and 1 patient chose the third round of fertility preservation therapy with fully informed consent, and CR was reached after 15 months. (3) There were 16 cases with pregnancy intention, with a total of 12 pregnancies, including 5 cases were natural pregnancy and 7 cases were assisted reproductive technology pregnancy. There were 5 live births. The follow-up time was up to May 2019, and the median follow-up time was 73 months (range 0-123 months). All 27 patients had disease free survival. Conclusions: Recurrent patients with AEH and EEC after achieving successful fertility-preserving therapy could choose fertility-preserving therapy again with comprehensive assessment and fully informed consent. After re-treatment, there is a certain tumor CR rate and pregnancy rate, while the close follow-up is required during treatment.

[Clinical analysis of adult onset orbital xanthogranuloma].

Objective: To investigate the clinical, imaging and pathological features of adult onset xanthogranuloma. Methods: Retrospective case series study.The clinical data of 4 adult patients with adult onset xanthogranuloma treated in the Tianjin Medical University Eye Hospital from 2015 to 2017 were analyzed. Results: There were 1 male and 3 females, aged 46-73 years, with an average age of 55 years. The duration of eyelid swelling was from 6 months to 6 years. One case was binocular and 3 cases were monocular. There were progressive enlargement of eyelid swelling and subcutaneous cord nodules with poor mobility and no tenderness in all 5 eyes. The eyelid skin in 2 patients (2 eyes) was bulging and yellow. CT examination showed swelling of the eyelids and soft tissue thickening in 5 eyes. There were lacrimal gland enlargement in 3 eyes, upper rectus muscle involvement in 3 eyes, external rectus muscle involvement in 1 eye, lower rectus muscle involvement in 1 eye, superior oblique muscle involvement in 1 eye, and involvement of both the superior and inferior rectus muscles in 1 eye. In 1 patient (1 eye), the lesion showed low and medium signals on T(1) weighted images and T(2) weighted images. Three patients (4 eyes) underwent color Doppler ultrasonography, showing the echo zone in the irregularly shaped eyelid was strong, the internal echo was uneven, the local echo was low, and the boundary was not clear. One of the eyes showed a blood flow signal. All patients underwent surgical resection. The pathological results showed infiltration of foamy tissue cells, Touton cells, lymphocytes and plasma cells. Immunohistochemistry demonstrated 3 patients (4 eyes) expressed CD68, and 1 patient (1 eye) expressed S-100. After 6 months to 2 years of follow-up, 3 patients had no recurrence. One patient developed eye discomfort at 6 months after surgery, and the symptoms were relieved after treatment with triamcinolone. Conclusions: Adult onset xanthogranuloma mainly manifest as eyelid swelling, periorbital mass and skin color changes, generally with no systemic involvement. Imaging examination mainly shows the involvement of soft tissues, lacrimal glands and muscles around the eyelids. The main features of the pathology are infiltration of foamy tissue cells, Touton giant cells, lymphocytes and plasma cells. (Chin J Ophthalmol, 2019, 55: 381-386).

[Analysis of sleep quality of a prison police].

Objective: To investigate the sleep quality of prison policemen and explore its influencing factors, so as to provide reference for improving the sleep quality of prison policemen. Methods: In August 2013, 177 policemen in a prison were selected by cluster sampling. The sleep quality of 177 prison policemen was investigated by Pittsburgh Sleep Quality Index Scale and General Situation Questionnaire, and the influencing factors were analyzed. Results: The PSQI scores of 177 prison policemen were (7.47+3.80). There were significant differences between the PSQI scores of prison policemen and the normal adult norm (P<0.05). According to the standard of poor sleep quality, 84 prison policemen (47.46%) had poor sleep quality, and the prison policemen scored higher on daytime dysfunction, subjective sleep quality, sleeping time and sleeping time components. Single factor t test and single factor variance analysis showed that there were significant differences in sleep quality among prison policemen in gender, age, educational level and job classification (P <0.05). The results of multiple stepwise regression analysis showed that gender, age and job classification entered the regression equation with PSQI total score as dependent variable (ß=0.167, 0.270, 0.222) . Conclusion: The sleep quality of prison policemen is worse than that of normal adults, and is affected by gender, age, job classification and other factors, which should be paid attention to by prison administrators.

Effects of different degrees of depression on inflammatory response and immune function in patients with ovarian cancer.

The aim of this study was to explore the effect of depression of different degrees on inflammatory response and immune function in patients with ovarian cancer. One hundred and eight cases of ovarian cancer according to the Federation Internationale of Gynecologie and Obstetrigue (FIGO) stage II~III who visited the Gynecology Department of Affiliated HongQi Hospital of MuDanJiang Medical University between September 2015 and May 2017 were enrolled in the study. After being hospitalized, they were divided into two groups according to their Beck Depression Inventory (BDI) scores. The total score of BDI is 63, with 0~4 for the normal group (25 cases), 5~13 for the mild depression group (24 cases), 14~20 for the moderate depression group (28 cases), and 21~63 for the severe depression group (31 cases). The immune function, inflammatory reaction, tumor markers [CA125, human epididymis protein-4 (HE4), insulin-like growth factor-I (IGF-I)], platelet technology and D-dimer index were compared between the four groups. The results showed that there were different levels of depression in patients with ovarian cancer in II~III stage, and the degree of depression could stimulate the level of serum-6, and TNF -α in serum increased. The proportion of CD3+, CD4+ and NK cells in patients with severe depression decreased, and their immunity also decreased. Depression increased the levels of CA125, HE4 and IGF-I in serum and ascites of ovarian cancer patients, and increased the risk of tumor progression and recurrence. Hypercoagulability existed in patients with ovarian cancer, and tumor associated depression could increase platelet count in plasma and increase D-dimer level. To sum up, depression can affect the level of micro inflammation in patients with ovarian cancer. In particular, depression can reduce cellular immune responses, affect the progression free survival of ovarian cancer patients, and reduce their overall survival rate.

[Application of decision curve on evaluation of MRI predictive model for early assessing pathological complete response to neoadjuvant therapy in breast cancer].

Objective: To construct a dynamic enhanced MR based predictive model for early assessing pathological complete response (pCR) to neoadjuvant therapy in breast cancer, and to evaluate the clinical benefit of the model by using decision curve. Methods: From December 2005 to December 2007, 170 patients with breast cancer treated with neoadjuvant therapy were identified and their MR images before neoadjuvant therapy and at the end of the first cycle of neoadjuvant therapy were collected. Logistic regression model was used to detect independent factors for predicting pCR and construct the predictive model accordingly, then receiver operating characteristic (ROC) curve and decision curve were used to evaluate the predictive model. Results: ΔArea(max) and Δslope(max) were independent predictive factors for pCR, OR=0.942 (95%CI: 0.918-0.967) and 0.961 (95%CI: 0.940-0.987), respectively. The area under ROC curve (AUC) for the constructed model was 0.886 (95%CI: 0.820-0.951). Decision curve showed that in the range of the threshold probability above 0.4, the predictive model presented increased net benefit as the threshold probability increased. Conclusions: The constructed predictive model for pCR is of potential clinical value, with an AUC>0.85. Meanwhile, decision curve analysis indicates the constructed predictive model has net benefit from 3 to 8 percent in the likely range of probability threshold from 80% to 90%.

[Clinical characteristics and risk factors in pregnancy with severe community-acquired pneumonia].

Objective: To analyze clinical characteristics of severe community-acquired pneumonia during pregnancy and its outcomes, and to explore the relevant risk factors. Methods: From September 2012 to September 2017, 324 398 pregnancies admitted in 7 tertiary hospitals were included. Clinical data of 33 cases of pregnancies with severe community-acquired pneumonia (severe pneumonia group) and 214 cases of pregnancies with common community-acquired pneumonia (control group) were reviewed retrospectively, including the clinical information, manifestations, laboratory examinations and pregnancy outcomes. Relevant risk factors were analyzed by multivariate logistic regression analysis. Results: (1) General data: pregnancies with severe community-acquired pneumonia accounted for 0.010% (33/324 398) of hospitalized pregnancies, the gestational age of two groups were (28±8) and (23±8) weeks, body mass index were (21.7±2.1) and (25.5±3.4) kg/m(2), rate of low income were 54.5% (18/33) and 31.8% (68/214) , respectively. The differences between two groups were all statistically significant (all P<0.05). No significant differences were found in age, pregnancy and parity times, rate of main pregnant complications such as diabetes and hypertension, educational level, asthma and onset seasons between two groups (all P>0.05). (2) Clinical data: the severe pneumonia group had significantly higher incidence of fever [100.0% (33/33) vs 75.2% (161/214) ], shortness of breath (90.9% vs 16.8%) compared with the control group (all P<0.05) .The median peripheral leukocytes counts were 12.3×10(9)/L and 10.2×10(9)/L, the hemoglobin level were (84±18) and (107±14) g/L,the albumin level were (26±4) and (37±3) g/L, the median serum urea nitrogen level were 3.7 and 2.4 mmol/L, the serum creatinine level were (72±25) and (45±11) µmol/L, respectively in two groups. The differences were all statistically significant (all P<0.05). No significantly statistical differences were found in coagulation indicator and cardiac function between two groups (all P>0.05). (3) Treatments: in severe pneumonia group, 12 patients (36.4%,12/33) needed invasive mechanical ventilation, 9 patients (27.3%,9/33) needed non-invasive mechanical ventilation, average time of mechanical ventilation was (7±4) days;8 patients (24.2%,8/33) with septic shock needed vasoactive drugs. However, there was no patient in control group needing mechanical ventilation and vasoactive drugs. (4) Pregnant outcomes: one patient (3.0%,1/33) died in the severe pneumonia group, while no death occurred in the control group. The hospital stay between two groups were (15.1±4.1) and (7.0±1.9) days, the rates of abortion and stillbirth between two groups were 42.4% (14/33) and 3.3% (7/214) , the rates of premature were 10/19 and 6.3% (13/207) , the rates of cesarean were 15/19 and 43.0% (89/207) , the rates of low birth weight newborn were 17/19 and 14.0% (29/207) , the rates of infected newborn were 15/19 and 10.1% (21/207) , the birth weights were (2 165±681) and (3 102±400) g, respectively. The differences between two groups were all statistically significant (all P<0.05). (5) Multivariate logistic regression analysis demonstrated that anemia, low body mass index, hypoproteinemia were risk factors for severe pneumonia in pregnancy (all P<0.05) . Conclusions: Pregnancy with severe community-acquired pneumonia may be complicated by multiple organ dysfunctions, lead to adverse outcomes. Anemia, malnutrition are risk factors for pregnancy with severe pneumonia. Active and effective treatment may improve its prognosis.
