我国灾难性卫生支出标准的界定：基于医疗支出对家庭基本生活消费的影响

目的：基于医疗支出对家庭基本生活消费的影响,对适合我国国情的灾难性卫生支出标准进行界定。方法：利用中国家庭追踪调查（CFPS）2012年、2014年、2016年和2018年四期的非平衡面板数据,运用双向固定效应模型和倾向得分匹配方法进行分析。结果：医疗支出强度与家庭基本生活消费并不是简单的线性关系,而是存在拐点的“倒U型”关系;异质性分析表明,医疗支出强度与家庭基本生活消费之间的“倒U形”关系主要表现在农村居民家庭和中等收入家庭,城市居民家庭和低收入家庭、高收入家庭不明显;适合我国实际情况的灾难性卫生支出标准与WHO提出的标准有所差异。建议：针对重点救助对象的医疗救助政策应该继续实施,且覆盖范围需不断扩大;以灾难性卫生支出为指标识别医疗支出型贫困,并根据我国国情制定其标准。     

A proposal for classification of oropharyngeal squamous cell carcinoma: Morphology and status of HPV by immunohistochemistry and molecular biology

The current three-tier grading system (well, moderate and poorly differentiated) used to morphologically classify head and neck squamous cell carcinoma (HNSCC) is inadequate for categorisation of oropharyngeal squamous cell carcinoma (OPSCC) owing to the lack of prognostic value. The aim of this study was to assess the validity of a classification system for OPSCC based on morphology and human papilloma virus (HPV) infection status. Haematoxylin and eosin slides of 121 patients (100 M, 21 F, age range 40-89 years) with OPSCC were reviewed and categorised as histological types I, II and III. The presence of HPV was assessed by immunohistochemistry with p16 and RNAscope In situ hybridization (ISH). The follow-up period was 36 months. Ninety-six patients were p16+ and clinical stage I. Patient survival with types I, II and III was 93%, 50% and 96%, respectively. Twenty-five patients were p16−: 10 clinical stage I and 15 stage III. Amongst this group, no type I morphology was identified. At follow-up, 65% of type II and 75% of type III patients were alive. All p16+ cases were also positive for E6/E7 mRNA high-risk HPV by ISH, while 23 p16− cases were negative and two were positive. Cox regression identified three predictors of mortality: older age (HR = 1.14, 95% CI = 1.06-1.23, P = .001); female gender (HR = 0.22.95% CI 0.05-0.88, P = .033); and type II morphology (HR = 13.1, 95% CI = 1.09-157.0, P = .043). OPSCC morphological classification in three sub-types, along with HPV infection status, seems to reflect the outcome of patients with OPSCC.     

The possible association between the presence of an MPO −463 G > A (rs2333227) polymorphism and cervical cancer risk

Purpose

The association between myeloperoxidase (MPO) polymorphism and the risk of cervical cancer is inconclusive. We performed a meta-analysis to clarify if a correlation exists between MPO polymorphism and the risk for developing cervical cancer.

Inverted variant of urothelial carcinoma of the urinary bladder: a report of three cases and a proposal for a new clinicopathologic entity

Inverted urothelial carcinoma (UC) without papillary areas is very rare; only 31 cases of three papers have been reported. The author herein reports three additional cases, and proposes the term “inverted variant” (IV) of UC. The materials were 3 cases of IV of UC, 5 cases of inverted papilloma (IP), and two cases of nested variant (NV) of UC. The three cases of IV of UC consisted of 56-year-old woman, 63-year-old man, and 78-year-old man. Presenting symptoms were hematuria in all cases. The cystoscopic findings were elevated tumors without papillary proliferations in all cases. The treatment was transurethral tumor resection (TUR-BT) in all cases. The sizes was 0.6 cm, 0.5 cm, and 3 cm. Microscopically, IV of UC showed inverted growth of atypical cells without papillary proliferations. Compared to IP, the inverted growth pattern was similar, but cytological atypia and thick trabeculae were noted in IV of UP while they were absent in IP. Compared to NV of UC, the growth pattern is different; NV of UC showed nested and vague tubular pattern. The cellular atypia is more pronounced in IV of UC than NV of UC. Immunohistochemically, p53 expression was seen in all the cases of IV of UC and in all the cases of NV of UC, while p53 expression was negative in all the cases of IP. Ki-67 labeling index was 25, 30 and 40% in IV of UC, 15 and 30% in NV of UC, and 3, 5, 6, 7, 9% in IP. Invasive features were seen in 1 case of IV of UC and 2 cases of NV of UC. In all cases of IV of UC, IP, and NV of UC, the TUR-BT, but one case of IV of UC, showed no recurrence after TUR-BT, while one case of IV of UC showed a recurrence. In conclusion, the IV and UC were structurally and cytologically very different from the NV of UC. The IV of UC was structurally similar to IP, but cellular atypia and thickened trabeculae were seen in IV and UC. p53 expression and Ki-67 labeling status were entirely different between in IV of UC and IP. The author proposes the term of IV of UC as a new clinicopathological entity.     

Human papilloma virus (HPV) status, p16INK4a, and p53 overexpression in epithelial malignant and borderline ovarian neoplasms

This investigation is the first to evaluate simultaneously human papilloma virus (HPV) status, p16(INK4a), and p53 immunoreactivity in epithelial ovarian neoplasms. The results were analyzed and correlated with histological type, histological grade, and survival of patients. Subtypes considered are papillary serous and mucinous. Polymerase chain reaction (PCR) analysis, performed in our previous study, had already demonstrated a small number of HPV-positive epithelial ovarian neoplasms. No significant correlation was found between the presence of HPV DNA and subtypes of ovarian neoplasms; thus, HPV cannot be considered responsible for epithelial ovarian neoplasm. Since p16 immunoreactivity was present in many other HPV-negative cases of epithelial ovarian neoplasms, this study suggests that p16 overexpression in some neoplasms of the female genital tract is not related to HPV carcinogenesis. A higher p53 expression rate observed between borderline and malignant serous tumors and between serous and mucinous neoplasms can confirm a recent dualistic model of ovarian carcinogenesis. According to this theory, low-grade serous carcinomas (serous intraepithelial carcinomas, serous borderline neoplasm, and ovarian mucinous neoplasms) (type I tumors) develop from mutations of KAS and BRAF, while high-grade serous carcinomas (type II tumors) develop from mutation of p53. In malignant neoplasms, for univariate analysis, patient survival seems to be related to p53, strong and diffuse p16 overexpression, and the stage of development of neoplasms at the diagnosis. In multinomial logistic regression, used to evaluate the role of staging, grading, p16 and p53 immunopositivity as predictor variables of unfavorable outcome of the disease, only p16 positivity was significantly related to the poor prognosis of the cancer.

沙眼衣原体感染与生殖道人乳头瘤病毒感染的关系及其与宫颈病变发生的相关性研究

目的研究女性生殖道人乳头瘤病毒(human papilloma virus,HPV)感染与沙眼衣原体(Chlamydia trachomatis,CT)感染的关系,及其与宫颈癌前病变和宫颈癌发生的相关性。方法以妇产科门诊患者540例为研究对象,所有患者均行HPV、CT和宫颈细胞学检查。对疑似宫颈病变的患者进一步行宫颈活检。根据HPV检测结果,将HPV检测阳性的患者140例设为观察组,HPV检测阴性的患者400例设为对照组,分析生殖道HPV感染与CT感染的相关性,以及其与宫颈病变发生的相关性。结果观察组宫颈病变发生率(21.4%)显著高于对照组(1.3%,P0.000 1)。按照HPV感染分型,进一步将观察组分为高危组(78例)、低危组(32例)和混合感染组(30例)。高危组(25.6%)和混合感染组(26.7%)宫颈病变发生率均显著高于低危组(6.3%,P=0.009;P=0.019)。同时,观察组CT感染率(27.1%)显著高于对照组(3.3%,P0.000 1)。HPV感染患者中,高危组(33.3%)和混合感染组(36.7%)的CT感染率均显著高于低危组(3.1%,P=0.021;P=0.019)。依据是否存在C T感染将观察组患者分为H P V单纯感染组和C T混合感染组。结果显示后者宫颈病变率(57.8%)显著高于前者(25.5%,P=0.046)。且CT混合感染组,高危HPV和混合HPV感染患者宫颈病变的发生率分别为39.3%和50.0%,均明显高于HPV单纯感染组中高危HPV和混合HPV感染患者,其发生率分别为16.0%和15.4%,差异均具有统计学意义(P=0.026和P=0.017)。Logistic回归分析显示高危型HPV感染(OR=2.180,P=0.018)、HPV和CT混合感染(OR=6.690,P=0.012)是宫颈病变发生的风险因素。结论女性生殖道CT感染与HPV感染密切相关,HPV和CT混合感染是宫颈癌前病变和癌变的独立风险因素。通过早期筛查女性生殖道HPV感染和CT感染,及时有效地治疗微生物混合感染,对进一步降低宫颈癌前病变和宫颈癌的发病率,提高临床治疗效果具有重要意义。     

Literature Review of Benign Müllerian Papilloma Contrasted With Vaginal Rhabdomyosarcoma

Study ObjectivesBenign müllerian papillomas of the genital tract are rare and, hence, can be mistaken for vaginal rhabdomyosarcoma on initial clinical review. This review of the literature will consolidate the previous cases of müllerian papilloma reported and looks for clues to differentiate the 2 entities.Design and SettingWe provide a case report and literature review, with patients from a pediatric adolescent gynecology clinic in a tertiary center.MethodsWe conducted a search of English-language publications from 1951 (the first case report) until January 2014 by using the search words “Müllerian papilloma” and “prepubertal bleeding.” References from previous published reports were also obtained for completeness.Main OutcomeLiterature review of benign müllerian papilloma.ResultsSince 1951, 56 cases of müllerian papilloma were reported, including 4 cases at our institution. Comorbid conditions were found in 31.5% of cases (with 3 cases associated with mesenchymal tumors). The average length of time from onset of symptoms (primarily vaginal bleeding) to diagnosis was 6.7 months (range, 1 day to 3 years), with only 1 case diagnosed incidentally. Median age of presentation was 5 years (range, 1 day to 52 years). Most cases were localized and resected with ease. Histology reveals complex papillary lesions without cytologic atypia.ConclusionBenign müllerian papilloma is distinguished from the more significant diagnosis of vaginal rhabdomyosarcoma by initial length of vaginal bleeding at presentation, lack of vaginal wall extension, ease of resection, and histopathology. This is compared with vaginal rhabdomyosarcoma which commonly exhibits both localized and distant spread.     

Preservation and redirection of HPV16E7-specific T cell receptors for immunotherapy of cervical cancer

Human papilloma virus (HPV) type 16 infections of the genital tract are associated with the development of cervical cancer (CxCa) in women. HPV16-derived oncoproteins E6 and E7 are expressed constitutively in these lesions and might therefore be attractive candidates for T-cell-mediated adoptive immunotherapy. However, the low precursor frequency of HPV16E7-specific T cells in patients and healthy donors hampers routine isolation of these cells for adoptive transfer. To overcome this problem, we have isolated T cell receptor (TCR) genes from four different HPV16E7-specific healthy donor and patient-derived human cytotoxic T lymphocyte (CTL) clones. We examined whether genetic engineering of peripheral blood-derived CD8+ T cells in order to express HPV16E711-20-specific TCRs is feasible for adoptive transfer purposes. Reporter cells (Jurkat/MA) carrying a transgenic TCR were shown to bind relevant but not irrelevant tetramers. Moreover, these TCR-transgenic Jurkat/MA cells showed reactivity towards relevant target cells, indicating proper functional activity of the TCRs isolated from already available T cell clones. We next introduced an HPV16E711-20-specific TCR into blood-derived, CD8+ recipient T cells. Transgenic CTL clones stained positive for tetramers presenting the relevant HPV16E711-20 epitope and biological activity of the TCR in transduced CTL was confirmed by lytic activity and by interferon (IFN)-gamma secretion upon antigen-specific stimulation. Importantly, we show recognition of the endogenously processed and HLA-A2 presented HPV16E711-20 CTL epitope by A9-TCR-transgenic T cells. Collectively, our data indicate that HPV16E7 TCR gene transfer is feasible as an alternative strategy to generate human HPV16E7-specific T cells for the treatment of patients suffering from cervical cancer and other HPV16-induced malignancies.
