Objective To established a diagnostic methods to idenfity Niemann-Pick disease type C (NPC) in China. Methods Two patients aged 5 and 20 years respectively who presented progressive neurologic regression and splenomegaly were subjected to filipin staining of cultured skin fibroblasts and genetic analyses of NPC1 gene. Results Although there were differences in onset ages and clinical presentations, filipin staining of the cultured skin fibroblasts confirmed the clinical diagnosis of NPC, showing an intense punctate pattern of fluorescence concentrating around the nuclei, consistent with the accumulation of unesterified cholesterol in NPC cells. Genetic sequence analysis further verified the results of filipin staining. The case 1 was compound heterozygous for M1142T(3425T>C),R1186H(3557T>C)and case 2 for Q88H(264G>T),469_470insGT.The latter 2 mutations were novel, and the possibility of polymorphisms was not supposed by analyzing 134 DNA samples obtained form normal controls. Conclusions Filipin stainning of the cultured skin fibroblasts is a reliable method to clinically diagnose NPC with a sensitivity. Genetic diagnose should be performed where genetic analysis is allowed.

OBJECTIVE: To compare the efficacy of metformin plus megestrol acetate (MA) with that of MA alone for treating endometrial atypical hyperplasia (EAH). METHODS: This pilot study included 16 EAH patients who met at least one metabolic syndrome (MS) criterion and received either adjunctive metformin plus MA (MET group) or MA monotherapy (MA group). Each patient in the MA group received 160 mg of MA daily, whereas patients in the MET group received the same dose of MA plus 0.5 g of metformin thrice daily. Treatment response was assessed by histological examination of dilation and curettage specimens obtained after 12 weeks of therapy. RESULTS: Each group had eight patients, and half of the patients in each group were diagnosed with MS. The complete response (CR) rate was 75% (6/8) in the MET group and 25% (2/8) in the MA group (p=0.105). Complications of MS did not affect the response rates in either group. In the MET group, 75% (3/4) of the patients had CR in the presence or absence of MS. In the MA group, 50% (2/4) of the patients with MS had CR, whereas no patient without MS had CR. No irreversible toxicities were observed. CONCLUSION: Metformin plus MA may be a potential alternative therapy for treating EAH, and the MS status of patients may have no effect on the efficacy of metformin plus MA therapy.

OBJECTIVE: Our previous study showed that insulin resistance (IR) was related to endometrial hyperplasia as well as endometrial cancer. But the exact impact of IR on fertility-sparing treatment in endometrial hyperplasic disease is unclear. This study investigated how IR affects fertility-sparing treatment in endometrial atypical hyperplasia (EAH) patients. METHODS: The 151 EAH patients received fertility-sparing treatment were retrospectively investigated. All patients received high-dose progestin combined with hysteroscopy. Therapeutic effects were evaluated by hysteroscopy every 3 months during the treatment. RESULTS: The median age was 33.0 years old (range, 21–54 years old). Sixty-one patients (40.4%) were insulin resistant. Three patients were excluded from the analysis because they chose hysterectomy within 3 months after initiation of progestin treatment. The 141 out of 148 (95.3%) patients achieved complete response (CR). No difference was found in cumulative CR rate between those with or without IR (90.2% vs. 95.6%, p=0.320). IR significantly affected therapeutic duration to achieve CR (8.1±0.5 months with IR vs. 6.1±0.4 months without IR, p=0.004). Overweight (body mass index [BMI]≥25 kg/m2) was associated with higher risk of treatment failure (odds ratio=5.61; 95% confidence interval=1.11–28.35; p=0.040) and longer therapeutic duration to achieve CR (7.6±0.5 months vs. 6.3±0.4 months, p=0.019). EAH patients with both IR and overweight (IR+BMI+) had the longest therapeutic time compared with other patients (8.8±0.6 months vs. 5.6±0.7, 6.3±0.4, and 6.4±0.8 months for IR−BMI+, IR−BMI−, and IR+BMI−, respectively, p=0.006). CONCLUSION: IR and overweight were associated with longer therapeutic duration in EAH patients receiving progestin-based fertility-sparing treatment.

Objective:
This study aimed to investigate the impact of polycystic ovary syndrome (PCOS) on fertility-sparing treatment in young patients with atypical endometrial hyperplasia (AEH) or endometrioid endometrial cancer (EEC).
Methods:
A total of 285 patients with EEC (n=76, FIGO stage IA, without myometrium invasion) or AEH (n=209) who received progestin-based fertility-sparing treatment were evaluated retrospectively. Among the 285 patients, 103 (36.1%), including 70 AEH cases and 33 EEC cases, were diagnosed with PCOS. General characteristics, cumulative 16- and 32-week complete response (CR) rate, pregnancy outcome and recurrence were compared between patients with or without PCOS.
Results:
The cumulative 16-week CR rate was lower in the PCOS group than in the non-PCOS group (18.4% vs. 33.8%, p=0.006). Patients with PCOS took longer treatment duration to achieve CR (7.0 months vs. 5.4 months, p=0.006) and shorter time to relapse after CR (9.6 months vs. 17.6 months, p=0.040) compared with non-PCOS group. After adjusting for patient age, body mass index, PCOS, homeostasis model assessment-insulin resistance index, and serum testosterone levels, we found that body mass index ≥25 kg/m2 (HR=0.583; 95% CI=0.365–0.932; p=0.024) and PCOS (HR=0.545; 95% CI=0.324–0.917; p=0.022) were significantly correlated with lower 16-week CR rate.
Conclusion
PCOS was associated with lower 16-week CR rate, longer treatment duration and shorter recurrence interval in patients with AEH or EEC receiving fertility-preserving treatment.

OBJECTIVES: Although patients with grade I and II endometrioid endometrial adenocarcinoma (EEA) are considered with good prognosis, among them 15%–25% died in 5 years. It is still unknown whether integrating estrogen receptor (ER) and progesterone receptor (PR) into clinical risk stratification can help select high-risk patients with grade I–II EEA. This study was to investigate the prognostic value of ER and PR double negativity (ER/PR loss) in grade I–II EEA, and the association between ER/PR loss and The Cancer Genome Atlas (TCGA) classification. METHODS: ER and PR were assessed by immunohistochemistry on hysterectomy specimens of 903 patients with grade I–II EEA. ER and PR negativity were determined when < 1% tumor nuclei were stained. Gene expression data were obtained from the TCGA research network. RESULTS: Compared with ER or PR positive patients (n=868), patients with ER/PR loss (n=35) had deeper myometrial infiltration (p=0.012), severer FIGO stage (p=0.004), and higher rate of pelvic lymph node metastasis (p=0.020). In univariate analysis, ER/PR loss correlated with a shorter progression-free survival (PFS; hazard ratio [HR]=5.25; 95% confidence interval [CI]=2.21–12.52) and overall survival (OS; HR=7.59; 95% CI=2.55–22.60). In multivariate analysis, ER/PR loss independently predicted poor PFS (HR=3.77; 95% CI=1.60–10.14) and OS (HR=5.56; 95% CI=1.37–22.55) for all patients, and poor PFS for patients in stage IA (n=695; HR=5.54; 95% CI=1.28–23.89) and stage II–IV (n=129; HR=5.77; 95% CI=1.57–21.27). No association was found between ER/PR loss and TCGA classification. CONCLUSION: Integrating ER/PR evaluation into clinical risk stratification may improve prognosis for grade I–II EEA patients.

Apolipoprotein A-Ⅰ (ApoA-Ⅰ), the predominant protein in plasma HDL, regulates cholesterol metabolism and exhibits anti-in-flammatory and antioxidant functions. Multiple clinical studies suggest that serum ApoA-Ⅰ levels are associated with the occurrence, development, and prognosis of malignant tumors. Laboratory research also shows that ApoA-Ⅰ and ApoA-Ⅰ mimetics exert antitumor ef-fects through antioxidation, immunoregulation, cholesterol metabolism, lysophosphatidic acid binding, and anti-angiogenesis. This pa-per reviews the role of ApoA-Ⅰ and ApoA-Ⅰ peptides in tumorigenesis and their potential value in diagnosis, treatment, and prognosis.
