Objective To assess true vocal fold (TVF) length and cricothyroid distance(CTD) with ultrasonography in male-to-female (MtF)transsexual voice surgery.Methods Five MtF transsexuals were divided into two groups according to their voice change surgery methods.High-frequency ultrasonography was used to measure the length of true vocal folds and cricothyroid distance.Measurements were compared pre-and post-surgery, and correlations with fundamental frequency (F0) were analyzed.Results The ultrasonography measurements clearly showed the laryngeal structure and TVF measurement marks.After vocal fold shortening and retrodisplacement of anterior commissure(VFSRAC) surgery, the ultrasonographic measurements showed that the shortening length of TVF were 0.37 cm(21%),0.69 cm(37%) and 0.40 cm(25%), respectively.The CTD in ultrasonographicimages were 1.0 cm pre-surgery of cricothyroid approximation (CTA) and-0.33 post-surgery of CTA.The displacement of cricoid cartilage was 1.33 cm, which was consistent with the laryngeal CT image.Conclusion Both TVF length and CTD can be shown by high-frequency ultrasonography, which can be used to quantitatively assessment and follow-up MtF transsexual voice surgery.

The true meanings of the terms of traditional Chinese medicine (TCM) need to be analyzed on a logical basis. It is not suitable to use a new term to interpret an old term of TCM, or arbitrarily specify the special term of TCM corresponding to some substances of modern medicine. In philosophy of language, language has a logical structure, which reflects the structure of the world, that is to say, language is the picture of the world in a logical sense. Using this idea, the authors collected the ancient literature on "kidney essence", and extracted each necessary condition for "kidney essence". All necessary conditions formed a sufficient condition to define the term "kidney essence". It is expected that this example can show the effectiveness of philosophy of language in analysis of the terms of TCM.

Objective To investigate the prevalence and influencing factors of sub-health status of the migrant workers in Dongguan City,in order to provide scientific preferences for preventing sub-health status.Methods Using the stratified random sampling method,740 migrant workers from ten towns(disetricts) in Dongguan city from August 2015 to August 2016 were recruited in this study.The sub-health measurement scale version 1.0 (SHMS V1.0) was applied to evaluate the sub-health status of migrant workers.The SHMS V1.0 scores were compared among migrant workers with different demographic characteristics,and the multivariate linear regression analysis was utilized to explore the influencing factors.Results A total of 718 valid questionnaires were collected,and the effective recovery rate was 97.03％.The sub-health status was detected in 483 migrant workers,and the prevalence rate of sub-health status was 81.6％.The migrant workers' subscale scores of physical sub-health (PS),mental subhealth (MS),social sub-health (SS) and total scale (TS) were (70.25-4-12.25),(64.21± 13.83),(62.21-4-13.87) and (66.114-11.15),respectively.The PS scale scores among migrant workers with different monthly household incomes per capita,and different inhabit situations;the MS scale scores among migrant workers with different ages,educations,marital status,monthly household incomes per capita,and inhabit situations;the SS scale scores among migrant workers with different genders,educations,and inhabit situations;and TS scores mong migrant workers with different educations,monthly household incomes per capita,and inhabit situations were statistically significant different (P＜0.05).The multivariate linear regression analysis showed that educations and inhabit situations were the influencing factors for TS score (P＜0.05).Conclusion The sub-health status of migrant workers in Dongguan City is serious,and the influencing factors are educations and inhabit situations.

Objective To investigate the pathological features of ovarian tumors in elderly women.Methods We retrospectively analyzed clinical data of 124 elderly patients with ovarian cancer who were admitted to our hospital from January 2015 to December 2017.Results Among the 124 elderly patients with ovarian tumors,there were 6 borderline tumors,19 malignant tumors,and 99 benign tumors.Postmenopausal vaginal bleeding and lower abdominal pain were the main symptoms of ovarian cancer in elderly patients.The incidence of abdominal pain in patients with benign ovarian tumors was significantly higher than in patients with malignant tumors (x2 =5.813,P ＜0.05);the incidence of postmenopausal vaginal bleeding in malignant tumors was significantly higher than in benign tumors(x2=8.123,P ＜0.05);the major pathological type of benign ovarian tumors was mucinous cystadenoma,while serous cystadenoma was the most common type of malignant tumors.Analysis of related factors showed that menopausal age was positively correlated with,and menarche age and number of pregnancies were negatively correlated with ovarian tumors;and there was no correlation with number of abortions.Conclusions Malignant ovarian tumors are common in elderly women.Clinically,attention to risk factors,early detection and diagnosis will help further reduce the malignant transformation rate and improve the quality of life for patients.

Objective To explore the effect of tea polyphenols on the growth of human papillomavirus 16 (HPV16) subgenes-immortalized human cervical epithelial cells (H8 cells).Methods Cultured H8 cells were divided into 5 groups to be treated with 0 (control group),6.25,12.5,25 and 50 mg/L tea polyphenols respectively for 24,36,and 48 hours,and then cell counting kit-8 (CCK8)assay was performed to detect cell proliferation.After 24 hours of incubation,flow cytometry was conducted to detect cell apoptosis and cell cycle,and fluorescence microscopy to observe the morphology of apoptotic cells.Results After incubation with tea polyphenols at different concentrations for 24,36 and 48 hours,the proliferation of H8 cells was inhibited,and 12.5 mg/L tea polyphenols could inhibit the relative growth rate of H8 cells in a time-dependent manner.Flow cytometry showed that there was a significant difference in cell apoptosis rate among the 6.25-,12.5-,25-,50-mg/L tea polyphenols groups and the control group (52.62％ ± 0.62％,52.22％ ± 0.72％,42.52％ ± 0.90％,45.96％ ± 2.11％,29.96％ ± 0.70％ respectively,F =272.0,P ＜ 0.05).Moreover,all the tea polyphenol groups showed significantly increased cell apoptosis rate compared with the control group (all P ＜ 0.05).Fluorescence microscopy showed karyopyknosis,nuclear fragmentation and other typical apoptotic morphological changes in H8 cells in tea polyphenols groups.There were significant differences in the percentage of cells in G1,G2 phase and cell proliferation index among the 5 groups (all P ＜ 0.05).Compared with the control group,the 6.25-,12.5-,25-mg/L tea polyphenols groups showed significantly increased percentage of cells in G1 phase (55.96％ ± 0.72％,54.12％ ± 3.20％,65.30％ ± 1.51％ respectively,all P ＜ 0.05),but significantly decreased percentage of cells in G2 phase (3.17 ± 1.82％,4.94 ± 1.46％,4.65 ± 4.26％ respectively,all P ＜ 0.05) and lower cell proliferation index(0.44 ± 0.01,0.46 ± 0.02,0.36 ± 0.01 respectively,all P ＜ 0.05).Conclusion Tea polyphenols can inhibit the proliferation of H8 cells,induce cell apoptosis,and block cell cycle progression.

Objective:To establish an air-pouch bladder cancer (APBCa) model and investigate whether it could be a new animal model to evaluate the efficacy of intravesical therapy through chemotherapeutics and BCG instillation.Methods:Filtered sterile air was injected subcutaneously into the backs of BALB/c Nude mice to create a 2.5 cm×3.5 cm air pouch. After 24 hours, human bladder cancer cells EJ were seeded on the inner face of the pouch wall to establish APBCa of human cancer (H-APBCa). Gemcitabine instillation was used to investigate whether chemotherapy could inhibit tumor growth in the H-APBCa model, and Tunel staining was used to verify the apoptosis of tumor cells 20-day treatment. Filtered sterile air was injected subcutaneously into the backs of C57BL/6 mice to create a 2.5 cm×3.5 cm air pouch. After 24 hours, mice bladder cancer cells MB49 were seeded on the inner face of the pouch wall to establish APBCa with intact immunity (I-APBCa). BCG instillation was used to investigate whether BCG could inhibit tumor growth in the APBCa model. Immunofluorescence was used to verify the infiltration of immune cells after 20-day treatment.Results:H-APBCa and I-APBCa mice models could be established by immune deficiency and intact mice. At day 20, chemotherapeutic instillation therapy could inhibit tumor growth (781.02±241.02 vs. 1213.88±214.02 mm 3, P<0.05) by inducing tumor cell apoptosis with statistically significant differences (77.33±4.63 vs. 14.67±2.60, P<0.05). BCG instillation was able to inhibit tumor growth (645.02±156.63 vs. 948.84±221.76, P<0.05) by increasing CD80 + macrophage (49.67±7.57 vs. 16.33±5.69, P<0.05) and T cells in the tumor with statistically significant differences (18.00±3.46 vs. 4.67±1.45, P<0.05). Conclusions:APBCa model could evaluate the efficacy of drug instillation and was expected to be a new animal model for studying drug for intravesical therapy.

Objective The aim of this study was to investigate the dosimetric advantages of Gating in the treatment of prima-ry hepatic cancer with large segmentation. Methods A retrospective analysis of 10 patients with primary liver cancer from August 2017 to November 2018 after interventional therapy was performed using three consecutive phases of end-tidal phase to achieve pa-tient-controlled large-segment radiotherapy. Ten patients underwent 4DCT localization scan,and 10 respiratory phase sequences were reconstructed by respiratory wave-form,and the images were transmitted to the MIM6. 7. 6 workstation. In the MIM workstation, full-time phase maximum density projection(MIP-10),full-time phase average density projection(Mean-10),end-expiration 3 phase maximum density projection(MIP-3) and end-expiration 3 phase average density projection( Mean-3) were generated re-spectively,where MIP was used for target delineation and Mean for dose calculation. The radiotherapy doctor delineated IGTV-10 and IGTV-3 on the MIM workstation,and released CTV-10,CTV-3,PTV-10 and PTV-3 to compare the volume differences of the target area. After the target area was drawn,the image was transmitted from the MIM workstation to the Eclipse treatment planning sys-tem,and the full-time phase plan(Plan-10)with the same conditions and three consecutive phase-phase gating plans(Plan-3) were prepared. The prescriptive dosage was given at 50 Gy/10 f/2weeks. Comparing the HI and CI of the target area,the comparison of organs at risk included: the average dose of liver Dmean,the irradiation volume of liver less than 15Gy,the Dmax of small intestine, the Dmax of colon, the Dmax of stomach, the average dose of the kidney Dmean, the heart Dmax, and the spinal cord Dmax. Results The volume of the target area delineated at the end of expiratory phase was less than that of the target area outlined by the full-time phase in IGTV,CTV and PTV,and the difference was statistically significant(P<0. 05). In the two groups of seven field coplanar lage-segment radiotherapy plans,the 3-phase respiratory gating plan significantly reduced the dose of the organs at risk, and the difference was statistically significant(P<0. 05). At the same time,there was no statistically difference in the HI and CI be-tween of the two groups(P>0. 05). Conclusion The gated target area delineation and planning design of the three consecutive pha-ses of end-tidal phase reduce the volume of IGTV,CTV and PTV target regions compared with the selection of full-time phase,and have obvious advantages in the planned dosimetry. The irradiation dose that threatens the organs is worthy of being promoted and ap-plied in the large-scale radiotherapy of liver cancer.

Objective:To evaluate the efficacy and safety of lactulose combined with polyethylene glycol for bowel preparation before colonoscopy in patients of different risks.Methods:A total of 208 patients undergoing colonoscopy were enrolled, including 108 high-risk and 100 low-risk patients. The high-risk patients were divided into group A (54 taking lactulose + polyethylene glycol) and group B (54 taking polyethylene glycol), and the low-risk patients were divided into group C (49 taking lactulose + polyethylene glycol) and group D (51 taking polyethylene glycol). The Boston bowel preparation score, cecal intubation time, withdrawal time, the detection rate of colonic polyps and adenoma, and the incidence of adverse reactions were observed.Results:Among the high-risk patients, the Boston bowel preparation score and adenoma detection rate in group A [(6.35±1.15) scores, 46.3%] were significantly higher than those in group B [(5.76±0.89) scores, 22.2%, both P<0.05], and the first defecation interval in group A was significantly shorter than that in group B [(1.20±0.85) h VS (3.29 ± 2.93) h, P<0.05]. There was no significant difference in adequate bowel preparation rate, polyp detection rate, frequency of defecation or incidence of adverse reactions between group A and B. In the low-risk patients, the first defecation interval in group C was significantly shorter than that in group D [(1.65 ± 1.35) h VS (3.42 ± 2.64) h, P<0.05], and the incidence of adverse reactions was significantly lower than that in group D (44.9% VS 64.7%, P<0.05). There was no significant difference in adequate bowel preparation rate, Boston bowel preparation score, adenoma detection rate, polyp detection rate or frequency of defecation between group C and D. Conclusion:For the high-risk patients, the effect of lactulose combined with polyethylene glycol for bowel cleansing is better than that of traditional polyethylene glycol in the improvement of the Boston bowel preparation score, adenoma detection rate, and the first defecation interval. For low-risk patients, lactulose combined with polyethylene glycol regimen has few advantages over traditional polyethylene glycol regimen.

GB7 acetate is a galbulimima alkaloid obtained from Galbulimima belgraveana.However,information regarding its structure,biological activities,and related mechanisms is not entirely available.A series of spectroscopic analyses,structural degradation,interconversion,and crystallography were performed to identify the structure of GB7 acetate.The MTT assay was applied to measure cell proliferation on human colorectal cancer HCT 116 cells.The expressions of the related proteins were measured by Western blotting.Transmission electron microscopy(TEM),acridine orange(AO)and monodansylcadaverine(MDC)staining were used to detect the presence of autophagic vesicles and autolysosomes.A transwell assay was performed to demonstrate metastatic capabilities.Oxygen consumption rate(OCR)and extracellular acidification rate(ECAR)assays were performed to determine the mitochondrial oxidative phosphorylation(OXPHOS)and glycolysis activity of HCT 116 cells.The data showed that GB7 acetate suppressed the proliferation and colony-forming ability of HCT 116 cells.Pretreatment with GB7 acetate significantly induced the formation of autophagic vesicles and autolysosomes.GB7 acetate upregulated the expressions of LC3 and Thr172 phosphorylated adenosine 5'-monophosphate(AMP)-activated pro-tein kinase α(p-AMPKα),which are key elements of autophagy.In addition,GB7 acetate suppressed the metastatic capabilities of HCT 116 cells.Additionally,the production of matrix metallo-proteinase-2(MMP-2)and MMP-9 was reduced,whereas the expression of E-cadherin(E-cad)was upregulated.Furthermore,GB7 acetate significantly reduced mitochondrial OXPHOS and glycolysis.In conclusion,the structure of the novel Galbulimima alkaloid GB7 acetate was identified.GB7 acetate was shown to have anti-proliferative,pro-autophagic,anti-metastatic,and anti-metabolite capabilities in HCT 116 cells.This study might provide new insights into cancer treatment efficacy and cancer chemoprevention.
