Abstract
ABSTRACT Gastric adenocarcinoma is a common malignant tumor of the digestive system. Primary diffuse large B-cell lymphoma (DLBCL) of the stomach is a common lymphoma originating from gastric submucosal lymphoid tissue, and the coexistence of DLBCL and adenocarcinoma is exceedingly rare. A 58-year-old woman came to our hospital for treatment because of a choking feeling after eating. During endoscopy, it was confirmed that multiple irregular ulcers were seen in the fundus and body of the stomach, and the surrounding mucosa was raised. The biopsy pathology showed poorly differentiated cancer, and the patient did not undergo immunohistochemical detection. A distal gastrectomy was performed. Pathological evaluation of resected specimens is as follows: gastric tubular adenocarcinoma and germinal center-type (GC)-DLBCL. No migration was found at the junction of the two tumors, forming a collision tumor. The patient received two cycles of Rituximab - Cyclophosphamide, doxorubicin, vincristine, prednisone (R-CHOP) chemotherapy, and there is no recurrence at present. We report a case of primary gastric adenocarcinoma colliding with the GC-DLBCL. Clinicians and pathologists should pay attention to it to avoid missed diagnosis.

Abstract
One-pot means was performed for the rapid preparation of copper nanoclusters (Cu NCs), which were employed as a fluorescence system for the sensitive apigenin measurement in pharmaceutical samples. Herein, CuCl2 aqueous solution was reduced to Cu NCs through ascorbic acid and the Cu NCs were protected through trypsin under 65 ℃ for 4 h. The entire preparation process was rapid, facile and environmentally friendly. The trypsin-capped Cu NCs were demonstrated through ultraviolet-visible spectroscopy, fluorescence spectroscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy and fluorescence lifetime, respectively. The Cu NCs revealed blue fluorescence with emission wavelength around 465 nm under the excitation wavelength of 380 nm. The fluorescence weakening feature of Cu NCs with apigenin was observed. On this basis, a facile and sensitive turn-off fluorescent nanoprobe for the sensing of apigenin in real samples was developed. The logarithm of relative fluorescence intensity revealed a good linear relationship with apigenin contents from 0.5 μM to 300 μM with the detection limit of 0.079 μM. The Cu NCs-based fluorescent nanosensor have been employed to measure the apigenin amounts in real samples such as medical saline, bovine and human serum. The results revealed excellent potential of this Cu NCs-based fluorescent nanoprobe for the convention computation of apigenin amounts in real samples.

Abstract
A 53-year-old female patient with pulmonary nodules for more than 3 years was admitted to Beijing Chao-Yang Hospital because of cough and sputum with shortness of breath after exercise for 4 months. In the first two and a half years, her pulmonary nodules remained stable, after that the nodules increased obviously with interstitial changes. After admission, a venous thromboembolic (VTE) event was quickly detected with a marked increase in D-dimer. Then, based on the clues of VTE examination, bronchoscopy, gastroscope, positron emission tomography-CT, head magnetic resonance and other examinations were performed. The final pathological diagnosis was lung adenocarcinoma, mainly solid with mucus secretion, with mediastinal hilar lymph node metastasis, intrapulmonary metastasis and gastric metastasis. Gene detection of lung and stomach histopathological tissues showed positive EML4-ALK fusion gene. The patient received therapies with crizotinib, alectinib in sequence and anticoagulation. After 20-month treatment, a telephone follow-up showed that there was no significant limitation in her daily activities.

Abstract
The Simple View of Reading (SVR) designates that reading comprehension is the product of decoding and listening comprehension and this conclusion has been supported by studies on school-aged native and nonnative speakers. However, it remains unknown whether SVR can be applied to adult second language (L2) learners. The current study addressed this issue by testing adult learners of Chinese as a second language with various proficiency levels and further extended the model by including word segmentation and word-meaning access, both of which are particularly crucial in reading Chinese. The results showed that listening comprehension only contributed to reading comprehension for the advanced learners, while decoding accuracy predicted reading comprehension regardless of Chinese proficiency. However, the total proportion of variance accounted for was relatively low, especially for the lower proficiency groups. Interestingly, word segmentation and word-meaning access explained a large proportion of the total variance and concomitantly decreased the apparent influence of word decoding. Taken together, these findings highlight that the individual characteristics of a given language can modulate the contributions of decoding and listening comprehension to predicting reading comprehension.

Abstract
OBJECTIVES Arterial stiffness is a common issue that may represent an indicator of vascular ageing. We aimed to investigate the association of arterial stiffness with the risk of functional disability and mobility limitation in older adults. DESIGN Prospective cohort study. SETTING AND PARTICIPANTS A total of 1699 older adults from the Rugao Longitudinal Ageing Study were included and analysed. MEASUREMENTS Arterial stiffness was assessed by brachial-ankle pulse wave velocity (baPWV). Functional disability and mobility limitation were evaluated by the activities of daily living and the Timed Up and Go test, respectively. The associations of baPWV and risk of functional disability and mobility limitation were analysed using logistic regression models. Restricted cubic spline regressions were applied to estimate the possible nonlinear relationships between them. RESULTS During the 3.5-year follow-up, 97 (10.00%) and 285 (31.11%) individuals were defined as new-onset functional disability and mobility limitation, respectively. After adjusting for confounding factors, elevated baPWV was significantly associated with a higher risk of incident functional disability (odds ratio [OR] 1.18, 95% confidence interval [CI] 1.06-1.31) and mobility limitation (OR 1.08, 95% CI 1.01-1.16). Additionally, consistent results were obtained from the stratified analyses of the different subgroups. Multivariable restricted cubic spline regression analysis further demonstrated that a near-linear association occurred between baPWV and the risk of incident functional disability and mobility limitation (P-overall < 0.01, P-nonlinear >0.05). CONCLUSION Arterial stiffness, as assessed by baPWV, was associated with the risk of functional disability and mobility limitation in this community-based cohort, and these associations were nearly linear.

Abstract
Objective: To investigate the effect of red blood cell folate on the prognosis of high-risk human papillomavirus (HR-HPV) infection. Methods: A total of 564 participants with low-grade cervical intraepithelial neoplasias (CINⅠ) were selected from the community-based married women cohort established in 2014. The general baseline information and factors related to HPV infection were collected. Meanwhile, HPV genotyping and levels of folate were measured. The subjects were divided into different levels of exposure group according to the folate levels and followed up for 24 months to observe the changes of HR-HPV infection status. There were four changes, including persistent infection, infection turned negative, from negative to positive and constant negative by comparing HR-HPV infection status at baseline and follow-up to 24 months. Results: 483 participators completed 24 months of follow-up observation, with a follow-up rate of 85.64% (483/564). The rates of persistent infection, infection turned negative, from negative to positive, and the constant negative were 52.45% (75/143), 47.55% (68/143), 19.71% (67/340), 80.29% (273/340), respectively. Our results demonstrated that the risk of persistent infection (aRR=2.50, 95%CI: 1.55-4.02) and from negative to positive (aRR=4.55, 95%CI: 2.52-8.23) in the low level of folate were significantly higher than that in the high level of folate, especially the risk of homotype persistent infection (aRR=2.72, 95%CI: 1.51-4.90). The risk of persistent infection (trend χ2=20.62, P<0.001), from negative to positive (trend χ2=31.76, P<0.001), persistent homotypic infection (trend χ2=20.09, P<0.001) increased with the decrease of red blood cell folate level. On the contrary, no similar results were found in persistent heterotypic infection. Conclusions: A low level of red blood cell folate could increase the risk of HR-HPV persistent infection and from negative to positive. In women with HR-HPV infection, the risk of persistent homotypic infection is higher.

Abstract
We have performed sound velocity and unit cell volume measurements of three synthetic, ultrafine micro/nanocrystalline grossular samples up to 50 GPa using Brillouin spectroscopy and synchrotron X-ray diffraction. The samples are characterized by average grain sizes of 90 nm, 93 nm and 179 nm (hereinafter referred to as samples Gr90, Gr93, and Gr179, respectively). The experimentally determined sound velocities and elastic properties of Gr179 sample are comparable with previous measurements, but slightly higher than those of Gr90 and Gr93 under ambient conditions. However, the differences diminish with increasing pressure, and the velocity crossover eventually takes place at approximately 20-30 GPa. The X-ray diffraction peaks of the ultrafine micro/nanocrystalline grossular samples significantly broaden between 15-40 GPa, especially for Gr179. The velocity or elasticity crossover observed at pressures over 30 GPa might be explained by different grain size reduction and/or inhomogeneous strain within the individual grains for the three grossular samples, which is supported by both the pressure-induced peak broadening observed in the X-ray diffraction experiments and transmission electron microscopy observations. The elastic behavior of ultrafine micro/nanocrystalline silicates, in this case, grossular, is both grain size and pressure dependent.

Abstract
Objective: To investigate the effects of polycyclic aromatic hydrocarbons (PAHs) exposure on the prognosis of high risk human papillomavirus (HR-HPV) infection. Methods: In this prospective study, 564 patients with low-grade cervical intraepithelial neoplasia confirmed by pathology were selected from the natural cohort population established by our research group in Shanxi province in 2014. Based on the baseline data of demographic characteristics and factors related to HPV infection, the concentrations of 1-hydroxypyrene in urine samples of the patients were determined by high performance liquid chromatography to define the exposure level of PAHs. At baseline survey and follow-up after 24 months, flow-through hybridization was used to detect HPV infection types, and to evaluate the prognosis of HR-HPV (persistent infection, negative conversion, positive conversion and persistent negative status). Results: Of the 564 subjects, 483 completed the follow-up, with a follow-up rate of 85.6% (483/564). Among them, the persistent infection rate was 52.4% (75/143), the persistent homotype infection rate was 35.7% (51/143), the negative conversion rate was 47.6% (68/143), the positive conversion rate was 19.7% (67/340), and the persistent negative rate was 80.3% (273/340). The follow-up results showed that the persistent infection rate (aRR=3.22, 95%CI: 1.85-5.62) and positive conversion rate (aRR=2.84, 95%CI: 1.64-4.94) of HR-HPV in high PAHs exposure group were higher than those in low PAHs exposure group, while the persistent negative rate (aRR=0.55, 95% CI: 0.43-0.70) of HR-HPV in high PAHs exposure group were lower than those in low PAHs exposure group. Based on restrictive cubic spline analysis, the results showed that the effects of PAHs exposure on persistent HR-HPV infection and persistent homotype infection showed an ascending linear dose-response relationship, while on HR-HPV positive conversion and persistent negative status showed an ascending and declining nonlinear dose-response relationship respectively (P<0.01). Conclusions: High PAHs exposure could promote persistent HR-HPV infection and persistent homotypic infection. Reducing PAHs exposure might conducive to HR-HPV continuous negative maintenance. Active prevention and control of PAHs exposure is of great significance to prevent HR-HPV infection and persistent infection.

Abstract
Objective: To evaluate the relationship between serum folate and the prognosis of cervical intraepithelial neoplasia grade I (CIN1) and the interaction between folate and high risk human papillomavirus (HR-HPV) infection. Methods: From a community-based married women cohort established in Jiexiu and Yangqu County of Shanxi Province from June to December 2014, a total of 564 eligible women with CIN1 by pathologically diagnosed were recruited. The pathological examination was performed again 12 months later. According to the prognosis of CIN1, participants were divided into CIN1 regression group, persistence and progression group, respectively. Nested case-control study was used to explore the relationship between serum folate and CIN1 prognosis, and additive model was used to analyze the interaction between serum folate and HR-HPV infection. Results: Among 564 CIN1 patients, 479 cases underwent pathological examination again, 331 were divided in CIN1 regression group and other 148 in persistence and progression group. The levels of serum folate in CIN1 regression group and persistence and progression group were (18.890±8.360) and (15.640±5.550) nmol/L, respectively, and the difference was statistically significant (Z=-6.937, P<0.001). HPV infection was detected in 154 patients, including 148 cases of HR-HPV infection and 6 cases of low risk human papillomavirus (LR-HPV) infection. Univariate analysis showed that there were significant differences in the age, passive smoking, frequency of pudendal cleaning, frequency of cleaning after sex, frequency of changing underwear, serum folate and HR-HPV infection between regression group and persistence and progression group (P<0.05). Multivariate logistic regression analysis showed that the frequency of pudendal cleaning (OR=0.422, 95%CI: 0.238-0.750), frequency of changing underwear (OR=0.574, 95%CI: 0.355-0.928), serum folate (13.06-16.78nmol/L: OR=4.806, 95%CI: 2.355-9.810; ≤13.05nmol/L: OR=8.378, 95%CI: 4.024-17.445), HR-HPV infection (OR=1.852, 95%CI: 1.170-2.933) were the independent influencing factors of CIN1 prognosis. Interaction analysis showed that the relative excess risk of low serum folate level and HR-HPV infection for the CIN1 persistence and progression was 4.992 (95%CI: 0.189-9.796), attributable proportion due to interaction was 0.552 (95%CI: 0.279-0.824), synergy index was 2.632 (95%CI: 1.239-5.588), aOR of serum folate≤16.78 nmol/L and HR-HPV infection positive was 9.055 (95%CI: 4.878-16.807). Conclusion: Low serum folate level could increase the risk of CIN1 persistence and progression, and might enhance the risk when combined with HR-HPV infection.

Abstract
This study is aimed at investigating the biological function of kinesin family member 3 C (KIF3C) in non-small cell lung cancer (NSCLC) progression and its upstream regulatory mechanism. Quantitative real-time PCR, Western blot and immunohistochemistry were adopted to examine microRNA-150-5p (miR-150-5p), microRNA-186-3p (miR-186-3p) and kinesin family member 3 C (KIF3C) expression levels. NSCLC cell proliferation, migration, and invasion were detected through cell counting kit-8 (CCK-8) assay, EdU assay, and Transwell assay. The metastasis of NSCLC cells was evaluated utilizing a pulmonary metastasis model in nude mice in vivo. The targeted relationship among KIF3C 3ʹUTR, miR-186-3p, and miR-150-5p were verified by dual-luciferase reporter gene assays. It was confirmed that in NSCLC tissues and cells, KIF3C expression level was increased and KIF3C overexpression promoted NSCLC cell proliferation and metastasis. Additionally, miR-150-5p and miR-186-3p directly targeted KIF3C to repress its expression. Our data suggest that KIF3C, which is negatively regulated by miR-150-5p and miR-186-3p, is an oncogenic factor in NSCLC progression.

Abstract
The characterization of observables, expressed via Hermitian operators, is a crucial task in quantum mechanics. For this reason, an eigensolver is a fundamental algorithm for any quantum technology. In this work, we implement a semi-autonomous algorithm to obtain an approximation of the eigenvectors of an arbitrary Hermitian operator using the IBM quantum computer. To this end, we only use single-shot measurements and pseudo-random changes handled by a feedback loop, reducing the number of measures in the system. Due to the classical feedback loop, this algorithm can be cast into the reinforcement learning paradigm. Using this algorithm, for a single-qubit observable, we obtain both eigenvectors with fidelities over 0.97 with around 200 single-shot measurements. For two-qubits observables, we get fidelities over 0.91 with around 1500 single-shot measurements for the four eigenvectors, which is a comparatively low resource demand, suitable for current devices. This work is useful to the development of quantum devices able to decide with partial information, which helps to implement future technologies in quantum artificial intelligence.

Abstract
Objective: To explore the effect of dietary water-soluble vitamins on the poor prognosis of low-grade cervical intraepithelial neoplasia (CINⅠ). Methods: A total of 564 participants with CINⅠ were selected from a community-based married women cohort established in 2014. The general baseline information was collected, and HPV genotyping was detected. A food frequency questionnaire was used to investigate dietary water-soluble vitamins' consumption and determine their exposure levels. The follow-up program was carried out for 12 months, and the regression, persistence, and progression of CINⅠ was determined according to histopathological results at 12-month. Results: The low-levels of dietary water-soluble vitamins could promote CINⅠ's persistence and progression, showing the increasing tendency of CINⅠ poor prognosis with the decrease of water-soluble vitamin levels. Especially folate, VB1, VB2, VB6, niacin, biotin, and VC (RR values were 15.22, 1.86, 1.92, 2.11, 2.98, 2.14, 2.19, respectively) played an important role. Considering the status of high-risk human papillomavirus (HR-HPV) infection, our results showed that the low levels of folate, niacin, biotin could promote the poor prognosis of CINⅠ. Conclusions: The low-level of dietary water-soluble vitamins could facilitate the poor prognosis of CINⅠ. In addition, folate, niacin, biotin were more effective on HR-HPV positive women.

Abstract
Objective: To investigate the diagnostic value of different vaginal micro-environmental factors in low-grade cervical intraepithelial neoplasia (CIN Ⅰ) and determine the optimal model in high-risk human papillomavirus (HR-HPV) infection. Methods: A total of 926 women, including 623 with normal cervical (NC) condition and 303 CINⅠ patients, had undergone pathological examinations, and were enrolled in the study. All the women were from a community previously established cohort. Vaginal cleanliness, pH, H2O2, β-glucuronidase, coagulase, sialidase, and leukocyte esterase (LE) were detected by the combined detection method aerobic vaginitis/bacterial vaginosis in vaginal secretions. HPV genotyping was performed by using the flow-through hybridization technology. The data were analyzed by SAS 9.2 and SPSS 23.0. Results: The vaginal cleanliness, pH, sialidase, and LE were determined as the representative vaginal micro-environment factors by principal component analysis. Based on logistic regression theory to analyze the ROC curve, the results showed that the highest sensitivity was with pH value (76.2%), and the highest specificity was with sialidase (90.9%). The area under ROC curve were higher in combination detection modes of sialidase+LE (0.714), pH+sialidase+LE (0.719), vaginal cleanness+sialidase+LE (0.713) and pH+vaginal cleanness+sialidase+LE (0.709). According to HR-HPV infection status, the TOPSIS method was used to analyze the combined detection optimal model. Specifically, we found that the best diagnostic model was pH+sialidase +LE (Ci=0.585) in the HR-HPV positive group and vaginal cleanness+sialidase+LE (Ci=0.641) in the negative group. Conclusions: The combined detection of vaginal microenvironment factors could be used for auxiliary diagnosis for CINⅠ. It would be more effective when detecting pH, sialidase, and LE in HR-HPV positive women while vaginal cleanness, sialidase, and LE in HR-HPV negative women at the same time.

Abstract
Objective: To describe the characteristics of high-risk human papillomavirus (HR-HPV) infection and its influences by vaginal micro-environmental factors. Methods: A total of 421 women with HR-HPV infection and normal cervix diagnosed by pathology were selected from a community cohort established earlier by our research group for a 24-month follow-up. The baseline data were collected at enrollment. The vaginal micro-environmental factors were detected by using the combined detection kit of aerobic vaginitis and bacterial vaginosis. And the HPV was detected by using the flow-through hybridization technology. According to the HR-HPV infection status in baseline and 24 months of follow-up, with the prognosis characteristics of HR-HPV infection described, the impact of vaginal micro-environmental factors on the prognosis of HR-HPV infection was explored as well. Results: Among 390 HR-HPV infected women who completed 24 months of follow-up, the top five types of persistent HR-HPV infection rate appeared as HPV16 (24.1%), HPV58 (22.2%), HPV53 (21.7%), HPV52 (20.0%), and HPV39 (11.8%), respectively. The results showed that women with abnormal vaginal pH (aOR=1.74, 95%CI: 1.08-2.80), abnormal neuraminidase (aOR=2.70, 95%CI: 1.52-4.83), or abnormal leucocyte esterase (aOR=3.41, 95%CI: 2.13-5.44), the risk of HR-HPV persistent infection increased. The abnormalities of neuraminidase and leukocyte esterase could increase the risk of persistent infection of homotype and heterotypic HR-HPV. Conclusions: HPV16 was prone to persistent infection. Abnormalities of vaginal pH, neuraminidase, and leukocyte esterase might increase the risk of HR-HPV persistent infection. Both the abnormalities of neuraminidase and leukocyte esterase play an essential role in the HR-HPV persistent infection.

Abstract
Objective: To study the relations of human papillomavirus (HPV) infection, vaginal micro-environmental disorder with cervical lesion. Methods: A total of 1 019 women including 623 with normal cervical (NC), 303 with low-grade cervical lesion (CIN Ⅰ) and 93 with high-grade cervical lesion (CIN Ⅱ/Ⅲ) were enrolled in this study from the communities in Shanxi province, China. Case-control method was adopted, with NC as the control group and CIN as the case group. Related information was collected including demographic characteristics and relevant factors related to cervical lesions. HPV genotypes were detected by flow-through hybridization technology. Vaginal pH was detected by the pH test paper. Vaginal H(2)O(2) was detected by the combined detection kit of aerobic vaginitis and bacterial vaginosis. Vaginal cleanliness was detected by smear method. Results: Data from the unconditional logistic regression analysis showed that HPV infection (CINⅠ: aOR=1.39, 95%CI: 1.01-1.90; CINⅡ/Ⅲ: aOR=11.74, 95%CI: 6.96-19.80), H(2)O(2) (CINⅠ: aOR=2.09, 95%CI: 1.47-2.98; CINⅡ/Ⅲ: aOR=4.12, 95%CI: 2.01-8.43), cleanliness (CIN Ⅱ/Ⅲ: aOR=2.62, 95%CI: 1.65-4.14), and composite indicators (CINⅠ: aOR=1.67, 95%CI: 1.24-2.25; CINⅡ/Ⅲ: aOR=4.24, 95%CI: 2.30-7.81) all had increased the risk of cervical lesion and the trend on the severity (P<0.001) of cervical lesions. Additionally, we observed a synergic effect between HPV infection and vaginal micro-environmental composite indicator in CINⅡ/Ⅲ. With or without HPV infection, the ORs value of CINⅠ caused by vaginal micro-environment disorder remained close. Conclusions: Results from our study revealed that vaginal micro-environmental composite indicator could increase the risk for cervical lesion, in particular with the high-grade ones which all posed stronger risks when combined with HPV infection. However, the role of vaginal micro-environment disorder in the occurrence of CIN Ⅰ should not be ignored.

Abstract
Objective: To compare the long-term oncological outcomes between laparoscopic and abdominal surgery in stage Ⅰa1 (lymph-vascular space invasion-positive, LVSI+)- Ⅰb1 cervical cancer patients with different tumor sizes. Methods: Based on the Big Database of Clinical Diagnosis and Treatment of Cervical Cancer in China (1538 project database), patients with stage Ⅰa1 (LVSI+)-Ⅰb1 cervical cancer who treated by laparoscopic or abdominal surgery were included. The 5-year overall survival (OS) and 5-year disease-free survival (DFS) between the two surgical approaches were compared under 1∶1 propensity score matching (PSM) in different tumor diameter stratification. Results: (1) A total of 4 891 patients with stage Ⅰa1 (LVSI+)-Ⅰb1 cervical cancer who underwent laparoscopy or laparotomy from January 1, 2009 to December 31, 2016 were included in the 1538 project database. Among them, 1 926 cases in the laparoscopic group and 2 965 cases in the abdominal group. There were no difference in 5-year OS and 5-year DFS between the two groups before matching. Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS (HR=1.367, 95%CI: 1.105-1.690, P=0.004). After 1∶1 PSM matching, 1 864 patients were included in each group, and there was no difference in 5-year OS between the two groups (94.1% vs 95.4%, P=0.151). While, the inferior 5-year DFS was observed in the laparoscopic group (89.0% vs 92.3%, P=0.004). And the laparoscopic surgery was associated with lower 5-year DFS (HR=1.420, 95%CI: 1.109-1.818, P=0.006). (2) In stratification analysis of different tumor sizes, and there were no difference in 5-year OS and 5-year DFS between the laparoscopic group and abdominal group in tumor size ≤1 cm, >1-2 cm and >2-3 cm stratification (all P>0.05). Cox multivariate analysis showed that laparoscopic surgery were not related to 5-year OS and 5-year DFS (P>0.05). In the stratification of tumor size >3-4 cm, there was no difference in 5-year OS between the two groups (P>0.05). The 5-year DFS in the laparoscopic group was worse than that in the abdominal group (75.7% vs 85.8%, P=0.025). Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS (HR=1.705, 95%CI: 1.088-2.674, P=0.020). Conclusions: For patients with stage Ⅰa1 (LVSI+)-Ⅰb1 cervical cancer, laparoscopic surgery is associated with lower 5-year DFS, and the adverse effect of laparoscopic surgery on oncology prognosis is mainly reflected in patients with tumor size >3-4 cm. For patients with tumor sizes ≤1 cm, >1-2 cm and >2-3 cm, there are no difference in oncological prognosis between the two surgical approaches.

Abstract
The X-linked genetic association is overlooked in most of the genetic studies because of the complexity of X-chromosome inactivation process. In fact, the biological process of the gene at the same locus can vary across different subjects. Besides, the skewness of X-chromosome inactivation is inherently subject-specific (even tissue-specific within subjects) and cannot be accurately represented by a population-level parameter. To tackle this issue, a new model is proposed to incorporate the X-linked genetic association into right-censored survival data. The novel model can present that the X-linked genes on different subjects may go through different biological processes via a mixed distribution. Further, a random effect is employed to describe the uncertainty of the biological process for every subject. The proposed method can derive the probability for the escape of X-chromosome inactivation and derive the unbiased estimates of the model parameters. The Legendre-Gauss Quadrature method is used to approximate the integration over the random effect. Finite sample performance of this method is examined via extensive simulation studies. An application is illustrated with the implementation on a cancer genetic study with right-censored survival data.

Abstract
Objective: To analyze the 13 years trend in proportion, risks factors and clinicopathological characteristics of young women with stage Ⅰa2 to Ⅱa2 cervical cancer by using multi-center data of cervical cancer in China. Methods: The clinicopathological data of 46 313 patients with cervical cancer treated from 37 hospitals in China were obtained from January 2004 to December 2016. Using clinical and pathologic data, each patient's stage was reclassified by the 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system. A total of 19 041 patients were selected according to the following criteria: FIGO stage Ⅰa2 to Ⅱa2, underwent type B or C radical hysterectomy and pelvic lymphadenectomy. All the patients were divided into two groups: the study group of 1 888 patients aged 35 years or younger and the control group of 17 153 patients aged over 35 years. The 13 years trend in proportion of young women with stage Ⅰa2 to Ⅱa2 cervical cancer, risks factors and clinicopathological characteristics of two groups were retrospectively analyzed. Results: (1) The total number of hospitalized patients with stage Ⅰa2 to Ⅱa2 cervical cancer increased annually. However, a downward trend of patients aged 35 years or younger was observed (P<0.01) . The constituent ratio of patients aged 35 years or younger was significantly greater during 2004-2010 than that during 2011-2016 [12.6% (820/6 484) and 8.5% (1 068/12 557) , respectively; χ(2)=82.101, P<0.01]. (2) Compared with patients aged over 35 years, patients aged 35 years or younger had an earlier age at menarche, a later age at marriage, lesser gravida and parity (all P<0.01). The positive rate of high-risk HPV infection was not statistically different between two groups (all P>0.05). (3) The proportions of stage Ⅰ, exophytic type and non-squamous histological type in patients aged 35 years or younger were clearly higher than those in patients aged over 35 years (83.4% vs 68.5%, P<0.01; 63.2% vs 56.2%, P<0.01; 13.9% vs 12.0%, P<0.05, respectively). Whereas the poor differentiation ratios of the two groups had no statistical significance (P>0.05). (4) As for the postoperative pathological risk factors, the rate of surgical margin involvement in patients aged 35 years or younger was lower than that aged over 35 years (1.1% vs 1.8%, P<0.05), and the rate of depth of stromal invasion >1/2 in patients aged 35 years or younger was lower than that in patients aged over 35 years (40.1% vs 50.9%, P<0.01). In addition, there were no significant difference in parametrial margin involvement, tumor size and lymph vascular space invasion between two groups (all P>0.05). Conclusions: The trend in proportion among hospitalized patients for stage Ⅰa2 to Ⅱa2 cervical cancer in young women is decreasing yearly. Compared with cervical cancer in middle-aged and elderly women, cervical cancer in young women have an earlier age at menarche, a higher proportion of stage Ⅰ patients and non-squamous histological type. In terms of the postoperative pathological risk factors, the rate of surgical margin involvement and depth of stromal invasion >1/2 in young women with cervical cancer are lower than in middle-aged and elderly women.

Abstract
Objective: To observe the changes of sex hormone and sex hormone-binding globulin (SHBG) levels in young male patients with hyperthyroidism before and after antithyroid drug (ATD) treatment. Methods: Between January 2015 and July 2016, forty male patients with hyperthyroidism aged 19-52 years (with an median age of 33.1 years) were enrolled in the Department of Endocrinology of Peking Union Medical College Hospital. Blood samples were taken before treatment and at 1 month, 2 months, 3 months and 5 months after treatment to evaluate thyroid function, follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone(T), free testosterone(FT), estradiol(E2), prolactin and SHBG. Results: A total of 40 patients were enrolled but only 35 patients completed the follow-up. The patients had high levels of thyroid function, SHBG and sex hormones before treatment. Before treatment, free thyroxine (FT(4)), free triiodothyronine (FT(3)), SHBG, LH, estradiol, testosterone and free testosterone was (0.30±0.12) pmol/L, (9.68±4.73) pmol/L, (146±111) nmol/L, (8.41±3.61) U/L, (19.9±7.7) pmol/L, (29.9±9.5) nmol/L and (0.24±0.08) nmol/L, respectively. After treatment, the level of triiodothyronine, thyroxine, FT(3) and FT(4) gradually decreased to normal (all P<0.001). Thyroid stimulating hormone (TSH) gradually increased to normal (P<0.001). LH and estradiol levels gradually decreased (all P<0.001). FSH decreased but the difference was not statistically significant. Prolactin did not change significantly. Testosterone and SHBG levels decreased significantly while the levels of free testosterone, free testosterone percentage (FT%), bio-available testosterone (BAT), bio-available testosterone percentage (BAT%), free androgen index (FAI) gradually increased and stabilized (all P<0.001). The difference was not statistically significant between T/LH and E2/LH before and after treatment (all P>0.05). However FT/LH gradually increased and its difference was statistically significant (P<0.001). Conclusion: The levels of LH, estradiol, testosterone and SHBG in male patients with hyperthyroidism significantly increased, while the free testosterone level decreased, but they all gradually returned to normal with the lowering of thyroid hormone levels during ATD treatment.

Abstract
目的 探讨成人急性淋巴细胞白血病(ALL)患者首疗程诱导治疗结束时微小残留病(MRD1)检测对自体造血干细胞移植(auto-HSCT)预后的意义。 方法 回顾性分析2006年2月1日至2017年4月30日行auto-HSCT的87例有流式细胞术MRD1检测结果的ALL患者临床资料,分析MRD1与ALL患者auto-HSCT后复发、生存的关系。 结果 26例(29.9%)ALL患者MRD1阳性。高危免疫表型比例在MRD1阳性组显著高于MRD1阴性组(34.6%对14.5%,P=0.038),初诊时年龄、性别、谱系(T/B)、免疫表型(标危/高危)、高白细胞计数(B-ALL>30×109/L或T-ALL>100×109/L)比例、伴高危染色体/基因比例、第1次完全缓解到移植的时间、预处理方案在MRD1阴性组和阳性组中差异均无统计学意义(P值均>0.05)。MRD1阴性患者、MRD1阳性患者的5年无白血病生存(LFS)率分别为75.7%、29.6%(P<0.001),总生存(OS)率分别为72.7%、47.3%(P=0.004)。多因素分析结果显示MRD1阳性是影响患者OS的独立危险因素(HR=3.007,95% CI 1.256~7.200,P=0.013),MRD1阳性和高危免疫表型是影响患者LFS的危险因素(HR=3.986,95% CI 1.813~8.764,P=0.001;HR=2.981,95% CI 1.373~6.473,P=0.006)。 结论 auto-HSCT不能逆转MRD1阳性患者的不良预后。MRD1阴性且在强化治疗中持续保持阴性患者可选择auto-HSCT治疗。

Abstract
OBJECTIVE Delirium Tremens (DT) is the most severe complication of alcohol withdrawal syndrome (AWS), and has a mortality rate of 1-5%. Baclofen is recommended for spasticity treatment, but it has recently been used for alcohol withdrawal symptoms reduction and alcohol abstinence. CASE REPORT A cervical spinal cord injury patient was treated for two years with oral baclofen 80 mg/day for spasticity. He is alcohol-dependent and a cannabis user and required an intrathecal baclofen (ITB) pump implant. A week after the implant, he stopped drinking, as "he didn't felt the urge anymore". The AWS appeared five days after the last alcohol intake and DT at 7 days. Diazepam 20 mg was used up to three times per day, but didn't seem to improve or reduce the anxiety, agitation, visual or auditory hallucinations. Two years later the patient remains alcohol abstinent and still on intrathecal baclofen. CONCLUSIONS Alcohol-dependent patients can abruptly stop their alcohol intake, while in continuous infusion of intrathecal baclofen. Baclofen can be useful in the acute treatment of AWS as it seems to reduce diazepam requirements and in long-term alcohol abstinence. In the presence of AWS, while on chronic baclofen, no dose reduction should be attempted, as it can worsen the AWS or trigger baclofen withdrawal.

Abstract
OBJECTIVE To report a case series of in vitro fertilization patients with premature ovarian insufficiency, who were treated with oral contraceptives to reduce follicle stimulating hormone levels. METHOD This was a consecutive case series in a tertiary teaching hospital in China. Twenty-two women with refractory and idiopathic premature ovarian insufficiency were administered a drospirenone/ethinylestradiol oral contraceptive orally. The main outcome measures were the number of oocytes retrieved and the number of embryos frozen. RESULTS There were total 106 oral contraceptive treatment cycles and 53 oocyte retrieval cycles in 20 patients (91%, 20/22; 2.4 cycles per woman, 53/22). The total number of oocytes retrieved was 48 in 17 patients (77%, 17/22; 2.2 oocytes per woman, 48/22), and the total number of embryos frozen was 33 in 16 patients (73%, 16/22; 1.5 embryos per woman, 33/22). CONCLUSION Oral contraception may be an effective method to induce ovulation for some patients with premature ovarian insufficiency.

Abstract
BACKGROUND Although tremendous efforts have been made to reduce rubella incidence, there are still 300 new cases of congenital rubella syndrome daily; thus, rubella infections remain one of the leading causes of preventable congenital birth defects. An effective surveillance system, which could be achieved and maintained by using an external quality assessment program, is critical for prevention and control of this disease. METHODS Armored RNAs, which are noninfectious and RNase-resistant, were used for encapsulation of the E1 gene of rubella virus and for preparation of a 10-specimen panel for external quality assessment. Thirty-two laboratories across mainland China that used nucleic acid tests for rubella virus RNA detection were included in the external quality assessment program organized by the National Center for Clinical Laboratories of China. RESULTS Different kinds of commercial kits were used by the laboratories for nucleic acid extraction and TaqMan real-time reverse-transcription PCR for rubella virus RNA detection; 99.2% sensitivity and 100% specificity were achieved in this external quality assessment program. CONCLUSIONS Most of the participating laboratories obtained accurate results for rubella nucleic acid tests, thereby achieving the quality required for regional rubella and congenital rubella syndrome elimination.

Abstract
Multiple myeloma (MM) is the second most prevalent hematologic malignancy. Aberrant microRNAs (miRNAs) expression has been shown to be involved in the pathogenesis of MM. In this study, we further demonstrated that miR-137 was significantly downregulated in MM and negatively correlated with clinical prognosis. Moreover, we described the epigenetic regulation of miR-137 and its association with progression-free survival in MM patients. Furthermore, overexpression of miR-137 in MM cell line (miR-137 OE) increased its sensitivity to bortezomib and eprirubicin in vitro. Also, some high-risk genetic abnormalities in MM, including deletion of chromosome 1p22.2, 14q or 17p13, and gain of chromosome 1p22.2 were detected in NCI-H929 empty vector (NCI-H929 EV) treated cells but not in the NCI-H929 miR-137 overexpression (NCI-H929 miR-137 OE) cells. Luciferase reporter assays demonstrated that miR-137 targeted AURKA. Ectopic expression of miR-137 strongly reduced the expression of AURKA and p-ATM/Chk2 in MM cells, and increased the expression of p53, and p21. Importantly, miR-137 overexpression together with bortezomib treatment significantly inhibited tumor growth in MM xenograft model. Taken together, this study demonstrates that miR-137 is epigenetically silenced in MM, and overexpression of miR-137 could reduce drug resistance and overcome chromosomal instability of the MM cells via affecting the apoptosis and DNA damage pathways.

Abstract
As a result of its spatial confinement in cardiomyocytes, neuronal nitric oxide synthase (nNOS) is thought to regulate mitochondrial and sarcoplasmic reticulum (SR) function by maintaining nitroso-redox balance and Ca2+ cycling. Thus, we hypothesize that ischemic postconditioning (IPostC) protects hearts against ischemic/reperfusion (I/R) injury through an nNOS-mediated pathway. Isolated mouse hearts were subjected to I/R injury in a Langendorff apparatus, H9C2 cells and primary neonatal rat cardiomyocytes were subjected to hypoxia/reoxygenation (H/R) in vitro. IPostC, compared with I/R, decreased infarct size and improved cardiac function, and the selective nNOS inhibitors abolished these effects. IPostC recovered nNOS activity and arginase expression. IPostC also increased AMP kinase (AMPK) phosphorylation and alleviated oxidative stress, and nNOS and AMPK inhibition abolished these effects. IPostC increased nitrotyrosine production in the cytosol but decreased it in mitochondria. Enhanced phospholamban (PLB) phosphorylation, normalized SR function and decreased Ca2+ overload were observed following the recovery of nNOS activity, and nNOS inhibition abolished these effects. Similar effects of IPostC were demonstrated in cardiomyocytes in vitro. IPostC decreased oxidative stress partially by regulating uncoupled nNOS and the nNOS/AMPK/peroxisome proliferator-activated receptor gamma coactivator 1 alpha/superoxide dismutase axis, and improved SR function through increasing SR Ca2+ load. These results suggest that IPostC protected hearts against I/R injury via an nNOS-mediated pathway.

Abstract
Background/Objectives: To investigate the effect of folate status on cervical intraepithelial neoplasia (CIN) progression and its relationship with high-risk human papillomavirus (hrHPV). Subjects/Methods: We evaluated 20 000 sexually active women aged <65 years in Yangqu County by using a questionnaire; the subjects were also screened using the ThinPrep cytologic test (TCT). Patients with abnormal TCT results (other than glandular cell abnormalities) who were willing to provide informed consent were further diagnosed using colposcopy and histopathological examination. We investigated 247 cases of low-grade cervical squamous intraepithelial lesions (LSIL), 125 cases of high-grade cervical squamous intraepithelial lesions (HSIL) and 877 controls. A 24-item food frequency questionnaire was filled out by the investigator to estimate the consumption of dietary folate. Positivity for hrHPV from residual exfoliated cervical cells was tested; serum folate was also measured. Results: The hrHPV infection rate in HSIL patients (77.6%) was higher than that in LSIL (33.2%) and control (32.0%) patients. Dietary folate intakes in controls, LSIL and HSIL were 306.9±176.6, 321.8±168.0 and 314.7±193.8 μg/kcal, respectively. The levels of serum folate in controls, LSIL and HSIL were 18.2±7.9, 15.9±7.1 and 14.3±7.5 nmol/l, respectively. Increased CIN correlated with higher rates of hrHPV infection and lower levels of serum folate. Conclusions: Low levels of serum folate may increase the risk of CIN progression. Furthermore, potential synergy may exist between low serum folate levels and hrHPV infection to promote CIN development.

Abstract
OBJECTIVE To investigate the incidence, influencing factors and intervention of gestrinone-related abnormal uterine bleeding at different dosage of gestrinone in the clinical treatment. METHODS This was a multicenter, randomized, control study of 195 Chinese women with endometriosis or adenomyosis from June 2011 to November 2013. The subjects were randomized into three groups with oral administration of gestrinone, 2.5 mg dose at one time; twice a week group: 67 cases with oral administration twice a week last three months; double dose first month group: 67 cases with oral administration triple times a week at first month, then twice a week for two months; three times a week group: 61 cases with oral administration three times a week last three months. The improvement of the abnormal uterine bleeding, the changes in estrogen, liver function and blood coagulation were evaluated. At the same time, B-ultrasound examination evaluation were performed. RESULTS (1) Three months later, the incidence of abnormal uterine bleeding in twice a week group was 30% (20/67), in double dose first month group and three times a week group were 7%(5/67) and 16% (10/61) respectively, there were significant difference between three groups (P<0.05). The incidence in double dose first month group was the most lower. (2) Univariate analysis showed that the dosage and ovarian size were the significant factors for abnormal uterine bleeding (OR=0.461,P= 0.003;OR=0.303,P=0.016); logistic regression analysis demonstrated that the risk of abnormal uterine bleeding in double dose first month group was the lowest when compared with twice a week group and three times a week group, the risk in twice a week group was 5-fold higher than that in double dose first month group (OR=0.211,P=0.011). The incidence of abnormal uterine bleeding in participants with abnormal ovarian volume results from ovarian cyst or ovarian surgery was significantly lower than those with normal ovarian volume (OR=0.304,P=0.018). (3) After the treatment of three months, there were no significant difference in alanine transaminase level between the groups (P>0.05). The body mass index significantly increased in three group (P<0.05), but there were no significant differences between the groups (P>0.05). As for blood coagulation, there were also no significant differences between the groups (P>0.05). CONCLUSIONS Double dose of gestrinone in the first month could significantly decrease the incidence of gestrinone-related abnormal uterine bleeding. It is a more optimied dosage of gestrinone and without severe side effects. CLINICAL TRIAL REGISTRATION Chinese Clinical Trial Registry, registration number: ChiCTR-TRC-12002327.

Abstract
Background and Objectives: Microtubules, the main components of spindles in the mitotic phase, can provide the suitable conditions for unlimited proliferation of tumor cells. Cytoskeleton microtubule-associated-Tau accelerates the progress of malignant tumor through microtubules. Currently, the expression of Cytoskeleton microtubule-associated-Tau in gastric cancer and the relationship between clinical pathological factors research has not yet been reported, so the report aims to elucidate the features of Cytoskeleton microtubule-associated-Tau expression in normal gastric tissue and gastric carcinoma tissue.Materials and Methods: The expressions of Cytoskeleton microtubule-associated protein-Tau protein and Cytoskeleton microtubule-associated protein-Tau mRNA were investigated in 60 cases of gastric carcinoma (cases) and 10 cases of normal gastric tissues (controls). Immunohistochemistry and RT-PCR were respectively used to detect the expression of Cytoskeleton microtubule-associated protein-Tau protein and Tau mRNA in the normal and carcinomatous gastric tissues.Results: The expressions of both cytoskeleton microtubule-associated protein-Tau protein and Tau mRNA in the carcinomatous gastric tissue were higher than in the normal gastric tissue (P<0.05). Likewise, both biomarkers were expressed significantly lower in the well-differentiated and moderately-differentiated gastric carcinoma was than in the poorly-differentiated one (P<0.05). Moreover, their expressions in the gastric carcinoma without lymph node metastasis was lower than in the gastric carcinoma with lymph node metastasis (P<0.05).Conclusion: The expressions of Cytoskeleton microtubule-associated-protein, Tau-protein and Cytoskeleton microtubule-associated-protein, Tau-mRNA were significantly different between the normal gastric tissue and the gastric carcinoma tissue, and were correlated with the degree differentiation and lymph node status.JCMS Nepal. 2015;11(3):6-11.

Abstract
In this paper we report a large-scale developmental study of early productive vocabulary acquisition by 928 Chinese-speaking children aged between 1;0 and 2;6, using the Early Vocabulary Inventory for Mandarin Chinese (Hao, Shu, Xing & Li, 2008). The results show that: (i) social words, especially words for people, are the predominant type of words in Chinese-speaking children's earliest productive vocabulary; (ii) overall, Chinese-speaking children's vocabulary contains greater proportions of nouns than other word categories, especially at the earliest vocabulary stage; and (iii) verbs tend to appear earlier for Chinese-speaking children as compared with English-speaking children at the same levels of vocabulary development. In addition, our study has identified the underlying variables that influence the age of acquisition of words, specifically, the interplay between the conceptual (imageability) and linguistic properties (word frequency, word length, and grammatical category) that jointly shape the development of Mandarin-speaking children's early vocabulary.

Abstract
Cancer-associated fibroblasts (CAFs) have been implicated in the development of resistance to anticancer drugs; however, the role and mechanism underlying CAFs in luminal breast cancer (BrCA) tamoxifen resistance are unclear. We found that stromal fibroblasts isolated from the central or peripheral area of BrCA have similar CAF phenotype and activity. In vitro and in vivo experiments showed that CAFs derived from clinical-luminal BrCAs induce tamoxifen resistance through decreasing estrogen receptor-α (ER-α) level when cultured with luminal BrCA cell lines MCF7 and T47D. CAFs promoted tamoxifen resistance through interleukin-6 (IL-6) secretion, which activates Janus kinase/signal transducers and activators of transcription (JAK/STAT3) and phosphatidylinositol 3-kinase (PI3K)/AKT pathways in tumor cells, followed by induction of epithelial-mesenchymal transition and upregulation of E3 ubiquitin ligase anaphase-promoting complex 10 activity, which targeted ER-α degradation through the ubiquitin-proteasome pathway. Inhibition of proteasome activity, IL-6 activity or either the JAK/STAT3 or PI3K/AKT pathways markedly reduced CAF-induced tamoxifen resistance. In xenograft experiments of CAFs mixed with MCF7 cells, CAF-specific IL-6 knockdown inhibited tumorigenesis and restored tamoxifen sensitivity. These findings indicate that CAFs mediate tamoxifen resistance through IL-6-induced degradation of ER-α in luminal BrCAs.Oncogene advance online publication, 9 June 2014; doi:10.1038/onc.2014.158.

Abstract
Benign prostatic hyperplasia (BPH) is a prevalent disease globally, and accumulating evidence has indicated an association between BPH, insulin resistance (IR) and diabetes. Exendin-4 is widely used in clinics, which could enhance the proliferation of pancreatic β cells. The ability of exendin-4 to promote tumorigenesis has been of concern, and whether exendin-4 would enhance the propagation of BPH is not fully understood. We aimed to determine whether glucagon-like peptide-1 receptors (GLP-1Rs) were expressed in rat prostate and to determine the effect of exendin-4 on prostate of BPH. Male Wistar rats were used and assigned to six groups: normal diet (ND), high-fat diet (HFD), HFD + exendin-4, HFD + BPH, HFD + BPH + exendin-4 and HFD + BPH + rosiglitazone group. After castration, steroids were injected subcutaneously for 4 weeks to induce BPH. Rats were kept on high-fat diet to induce IR. Treatment groups were treated with exendin-4 and rosiglitazone. Prostatic index and HOMA-IR index were used to evaluate the prostatic hyperplasia status and the degree of IR respectively. The expression of GLP-1R was indicated not only by immunohistochemistry, but also by Western blot analysis. The expression of GLP-1R was significantly higher, and HOMA-IR index and body weight significantly decreased after administration of exendin-4. However, no significant differences in the prostatic index were observed between exendin-4 treatment groups and non-exendin-4 treatment groups. Prostatic index was not influenced by exendin-4 maybe by improving IR and weight loss.
