Eliminat Cervical Cancer, Focusing on Primary Prevention / 肿瘤防治研究

As one of the most severe malignant tumors, cervical cancer poses a significant threat to women. In 2020, the World Health Organization (WHO) introduced the "Global Strategy to Accelerate the Elimination of Cervical Cancer" in response to well-established tertiary prevention measures. Primary prevention measures prioritize health education and the administration of prophylactic human papillomavirus (HPV) vaccines. China currently offers five HPV vaccines supported by extensive research data specific to the Chinese population. This paper discusses the application of HPV vaccines in China and related issues that need to be paid attention to.

Screening for cervical cancer and diversion of abnormal screening results / 中国医师杂志

Cervical cancer is still a serious threat to the health of women in China. The current strategy is a three-level prevention strategy, among which the diversion of screening and screening abnormalities in the secondary prevention is an important link in preventing cervical cancer. For more than 20 years, China has implemented diversified screening methods such as cytological examination, high-risk human papillomavirus (HPV) testing, and naked eye screening. With the discovery that high-risk HPV infection is closely related to the occurrence of cervical cancer, the screening method for cervical cancer has shifted from cytological examination to HPV testing as the preferred screening method. This article introduces the advantages and disadvantages of high-risk HPV testing and cytological examination as screening methods, and proposes the issues that need to be paid attention to in screening; The principle of diverting screening abnormalities was proposed, and it was proposed that in the process of diverting, individualized and refined management principles should be implemented for screening abnormality projects based on the patient′s age and fertility requirements.

Effectiveness of the Five Elements Music Therapy in Relieving Stress with Different Cultural Backgrounds / 世界科学技术-中医药现代化

Objective To explore the effectiveness of the Five Elements Music Therapy(FEMT)in relieving stress in participants with different cultural backgrounds,and to compare the differences between the FEMT and the Western Art Music Therapy(WAMT)in stress relief.Methods This was a comparative pilot randomized pre-post repeated measures study,37 subjects were allocated with 2 dropped out,with an inclusion-ended sample of 35 subjects,23 from Canada and 12 from China.After informed consent,all subjects were randomly assigned to listening to either Five Elements Music or Western Art Music at home for 30 minutes,twice a week for four weeks.Participants were asked to use headphones,measure their pulse rate before and after each session,and fill out five questionnaires,including a background and demographic survey(reporting age,gender,education,cultural background,listening experience).Self-assessment of stress(pre-post after each session),General Hospital Anxiety/Depression Scale(HADS,weekly after 2nd session),Perceived Stress Survey(PSS,weekly after 2nd session),the Music Therapy Intervention Survey(MTIS,pre-post each session).Results ①There was a significant decrease in self-assessed stress scores after the second session in the FEMT compared with the WAMT group(t=-2.057,P=0.046).②In both groups,there was a significant decrease in stress scores pre-post treatment in each group(WAMT t=5.026;FEMT T=7.645,P=0.000).③There was no significant difference between the two groups in post-intervention HADS scores(P>0.05);In the Chinese sample,there was a significant difference in HADS scores after the eighth session in both FEMT and WAMT groups(t=-3.862,P=0.003),and a statistically significant difference in HADS pre-post intervention in the FEMT((t=5.117,P=0.004).There was a significant difference in MTIS pre-post treatment in the WAMT(t=-2.572,P=0.023),but in not the FEMT group(t= 1.331,P=0.207).Conclusion This pilot trial explores a safe and feasible self-administered music therapy approach for stress in two distinct cultural groups,and for the first time provides preliminary comparison and evidence of effectiveness of FEMT and WAMT in alleviating stress and anxiety.Further investigation with bigger randomized samples is needed to elucidate the effects of different kinds of music and cultural groups on stress and anxiety levels.

Effect of ultrasound-guided intervention with methotrexate combined with lauromacrogol on uterine wall thickness and menstrual recovery time in patients with uterine scar pregnancy / 中国基层医药

Objective:To investigate the effects of ultrasound-guided intervention with methotrexate combined with lauromacrogol on uterine wall thickness and menstrual recovery time in patients with uterine scar pregnancy.Methods:Sixty patients with uterine scar pregnancy who received treatment in Jinhua Wenrong Hospital, Jinhua Central Hospital, and Yiwu Maternity and Children Hospital from February 2019 to February 2020 were included in this study. They were randomly assigned to receive either uterine artery embolization treatment ( n = 30, control group) or ultrasound-guided interventions with methotrexate combined with lauromacrogol ( n = 30, study group). The success rate of treatment, uterine wall thickness at the scar, menstrual recovery time, hospitalization time, hospitalization expenses, incidence of adverse reactions, serum levels of beta-human chorionic gonadotropin (β-HCG) and high sensitivity C-reactive protein (hs-CRP) after 7 days of treatment and uterine wall thickness before and after treatment were compared between the study and control groups. Results:After treatment, the success rate of treatment in the study group was significantly higher than that in the control group [96.67% (29/30) vs. 70.00% (21/30), χ 2 = 7.680, P < 0.05]. Before treatment, there were no significant differences in β-HCG and hs-CRP levels between the control and study groups ( t = -0.197, 0.197, both P > 0.05). After treatment, serum level of β-HCG in the control and study groups was significantly decreased ( t = 22.803, 10.233, both P < 0.01), and serum level of hs-CRP in the control and study groups was significantly increased ( t = -16.357, 7.854, both P < 0.001) compared with before treatment. After treatment, there were no significant differences in serum β-HCG and hs-CRP levels between the control and study groups ( t = 20.413, -20.306, both P < 0.05). After treatment, the incidence of adverse reactions in the study group was significantly lower than that in the control group [6.67% (2/30) vs. 30.00% (9/30), χ 2 = 5.455, P < 0.05). After treatment, menstrual recovery time, hospitalization time and hospitalization expenses in the study group were shorter or less than those in the control group ( t = 5.080, 5.398, 7.599, all P < 0.05). There was no significant difference in the thickness of uterine wall at the scar site between the two groups ( t = -1.045, P > 0.05). Conclusion:Ultrasound-guided intervention with methotrexate combined with lauromacrogol for treatment of uterine scar pregnancy can effectively increase the success rate of treatment, promote the restoration of menstruation, shorten the length of hospital stay, and is highly safe.

Pythium rishiriense sp. nov. from water and P. alternatum sp. nov. from soil, two new species from Japan.

In an investigation of Pythium species in natural ecosystems of Rishiri Island in Northern Japan, two new species, Pythium rishiriense and P. alternatum, were identified based on morphological and molecular analyses. Pythium rishiriense differed morphologically from other Pythium species by its characteristic oogonial formation which occasionally arranged in chains. Pythium alternatum differed morphologically from other Pythium species by its distinguishing sexual organs where oogonia occasionally arranged alternately with antheridia in chains. Pythium rishiriense is a fast growing, high-temperature loving species, while P. alternatum is a slow growing species. Phylogenetic analyses based on the internal transcribed spacer region and cytochrome c oxidase 1 gene sequences showed that these two species are clearly separate from morphologically similar species.

Survey of the acceptance status of HPV self-sampling screening in female population for cervical cancer / 中华妇产科杂志

Objective To investigate the acceptance of HPV self-sampling mode in cervical cancer screening population and explore its feasibility. Methods From March 5 to 15, 2018, researchers investigated women who participated in cervical cancer screening organized by Beijing Shunyi Women＇s and Children＇s Hospital in the form of questionnaires. Questionnaires were conducted on their acceptance status and the factors that affect the self-sampling experience. The specific contents of the questionnaires were as follows: (1) the experience of using self-sampling included operability, comfortable, sample time-consuming, bleeding or not after sampling; (2) psychological changes after self-sampling, including the willingness to accept self-sampling again, the worrying problems during self-sampling process. According to whether or not have operating video guidance, the self-sampling experience and psychological changes after self-sampling were compared. Results (1) There were 1 375 women participated in the questionnaire survey, and 86.55% (1 190/1 375) of them thought the self-sampling was convenient, 78.40% (1 078/1 375) thought it was not uncomfortable, 88.58% (1 218/1 375) thought the sampling time was fast (less than 5 minutes), 94.04% (1 293/1 375) self-sampling without bleeding; and 83.27% (1 145/1 375) were willing to self-sampling for cervical cancer screening again, 85.82% (1 180/1 375) were afraid of inaccurate sampling. (2) Among the 1 375 women, 1 202 were in the video guidance group and 173 were in the non-guidance group. The self-sampling experience of women in video guidance group was better than those of non-guidance group in operability, comfortable, sampling time-consuming and bleeding after sampling. The proportion of women who willing to self-sampling again was higher than that of non-guidance group (86.69% vs 59.54%, respectively). The proportion of women who worried operating incorrectly was lower than that of non-guidance group (11.23% vs 32.37%, respectively). The differences were significant (all P<0.05). Conclusions Self-sampling for HPV testing in cervical cancer screening is easy to operate and has little discomfort complaint. It is feasible in cervical cancer screening. Operational video guidance during the screening process could effectively improve the women＇s experience and willingness to self-sampling again in the future.

Study on clinical management of HPV+/Pap-during cervical cancer screening / 中华妇产科杂志

Objective To study the clinical management way for HPV+/papanicolaou (Pap)-during cervical cancer screening.Methods To analyze retrospectively the data from the patients who had loop electrical excision procedure (LEEP) for biopsy confirmed cervical intraepithelial neoplasia (CIN)Ⅱ in Peking University People's Hospital from Jan.2010 to Dec.2014.Results (1) For biopsy confirmed CINⅡ,HPV positive rate was 98.5％ (135/137),Pap test positive [≥atypical squamous cell of undetermined significance (ASCUS)] rate was 69.3％ (95/137),there was significant difference between them (x5=43.32,P＜0.01).(2) For the 42 patients with HPV+/Pap-,whose cytology slides were reviewed again.Among them,the interpretations of there were 16 cases confirmed as the same before,while 26 cases were changed to abnormal (≥ASCUS).Cytology be misdiagnosed was 19.0％ (26/137) at the first review.Among the 26 cases,13 (50.0％) cases were missed for the little amount of abnormal cells,8 (30.8％) cases for mild atypical morphology changed;the other 5 (19.2％) cases missed for stain problems.(3) For the cervical LEEP samples,37 cases of the pathology diagnosis were upgrade to CIN Ⅲ+,among them,2 cases of microinvasive cervical carcinoma,1 case of invasive cancer,34 cases of CIN Ⅲ;37 cases were CINⅠ or no lesion found;63 cases were still CIN Ⅱ.Four to six months later after LEEP,the cytology abnormal rate was 11.7％ (16/137),and the HR-HPV positive rate was 34.3％ (47/137).Conclusions Compared with cytology alone,cytology combined with HPV testing increase the sensitivity of cervical high grade lesion.For the cases of HPV+/Pap-cases,the cytology slides should be reviewed.The quality control of cervical exfoliate sample collection and interpretation should be strengthened.LEEP procedure is not only a treatment method,but also it could provide samples to confirm the diagnosis.

Objective To investigate the effect of Tegafur, Gimeracil and Oteracil Potassium Capsules ( TS-1 ) on peripheral blood tissue polypeptide antigen (TPS), soluble MHC class I chain-related molecules A (sMICA), hypoxia-inducible factor-1 (HIF-1α) and human epidermal growth factor receptor 2 ( Her-2 ) in the treatment of patients with advanced cervical cancer.Methods 80 cases with advanced cervical cancer were selected and divided into two groups, 40 cases in the control group were treated with routine clinical therapy, 40 cases in the experimental group were treated with TS-1.Tumor markers, TPS,sMICA,HIF-1αand Her-2 were compared before and after the treatment.Results Compared with the control group, the levels of tumor antigen TA-4,carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCCA) in the experimental group were lower (P<0.05); the TPS, HIF-1, sMICA and Her-2 were lower (P<0.05), and the total effective rate in the treatment group was higher (P<0.05).Conclusion TS-1 has a obvious clinical efficacy in the treatment of advanced cervical cancer.It is speculated that the possible mechanism may reduce the serum tumor marker levels via reducing the TPS and SMICA, HIF-1 alpha, HER-2 levels.

Effect of neonatal resuscitation training in both Mandarin and Uygur in Uygur area in Xinjiang,China / 中华围产医学杂志

ObjectiveTo explore an appropriate way and its effect on neonatal resuscitation training in Uygur area of Xinjiang, China.MethodsFrom October 2014 to February 2015, obstetricians, neonatologists (pediatricians), midwives and anesthetists from Turpan Region Central Hospital, Turpan City People's Hospital,Aksu Region First People's Hospital and other five hospitals at county level were chosen to attend the training course of neonatal resuscitation. The textbook for the course was Guidelines for Resuscitation which had been translated to Uygur language from English and the class was lead by less than ten Uygur trainees with Mandarin and Uygur when necessary in addressing some difficult or important points. The duration of theoretic courses took 6 h and the operational course took 8 h. Theorectical exam was taken before, immediately after and three months after (before re-training) the training. The accuracy rate was applied to assess the effect of training through evaluation for each resuscitation techniques. Repeated measures analysis of variance andChi-square test were used for statistical analysis.ResultsA total of 220 health care staff were included in the study. The average score of theoretical examination after the training was higher than that before (85.68±8.52 vs 65.37±12.08,t=18.532,P=0.000), and that before re-training was lower than that after training (80.08±12.70 vs 85.68±8.52,t=-4.943,P=0.000). After the training, the proportions of Done in each item, including rapid assessment, preliminary resuscitation, correct positive pressure artificial ventilation, external cardiac massage together with artificial ventilation, proper endotracheal intubation and proper administration of resuscitation drugs, were all higher that those before [72.7%(160/220) vs 1.4%(3/220), 40.0%(88/220) vs 0%(0/220), 15.9%(35/220) vs 0%(0/220), 37.7%(83/220) vs 8.2%(18/220), 51.8%(114/220) vs 5.9%(13/220) and 48.2%(106/220) vs 10.5%(23/220), allP<0.01]. But at the time before re-training, only one proportion ofDone which was higher than those immediately after initial training was proper administration of resuscitation drugs [49.6%(109/220) vs 48.2%(106/220),χ2=9.129,P<0.05].ConclusionBilingual (Mandarin and Uygur) neonatal resuscitation training in Xinjiang minority areas might enhance the recovery skills for local medical personnel.

Clinical implications and prognostic value of single and combined biomarkers in endometrial carcinoma / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Endometrial carcinoma is one of the most common gynecological cancers and the incidence has been increasing. This study was to identify the relationship of estrogen receptor (ER), progestrone receptor (PR), P53 protein, Ki-67 and phosphatase and tensin homolog deleted on chromosome ten (PTEN) with endometrial carcinoma, the assessment of these biomarkers and their association with clinicopathological parameters was performed.</p><p><b>METHODS</b>A total of 198 cases of primary endometrial carcinoma were investigated for ER, PR, Ki-67, P53, and PTEN antigens by immunohistochemical methods. The association of these markers with age, menopause status, histological type, FIGO stage, grading, depth of invasion, lymph node involvement and serum tumor marker was examined.</p><p><b>RESULTS</b>The percentages of Ki-67- and P53-negative endometrial tumors were significantly higher in ER-positive compared with ER-negative tumors (both P = 0.000). The same trend was evident with PR status. The percentage of PTEN-positive tumors was significantly higher in PR-positive compared with PR-negative tumors (P = 0.021), but was no difference in tumors with different ER status. There was no clear association between PTEN positivity and clinicopathological parameters except more relevance with endometrioid histotype (P = 0.013). There was a statistically significant difference in the distribution of the different combined biological factors examined in disease-free survival.</p><p><b>CONCLUSIONS</b>ER and PR status were significant predictors with staging, grading and recurrence. P53 and Ki-67 expression were inversely correlated with both ER and PR expression and have more aggressive clinicopathological features. PTEN expression was inversely correlated with PR expression but not with ER expression. The combined type of ER+PR+P53-PTEN+ was in the majority in endometrial cancer and seemed to be related to better clinical outcome. The combination of ER-PR-P53+PTEN- represented the worst disease-free survival and was strongly associated with poorest survival rate.</p>

Predictors of recurrence and prognosis in patients with stage Ⅰ and Ⅱ endometrial carcinoma / 中华妇产科杂志

Objective To explore the high-risk clinicopathological features for the recurrence and prognosis of endometrial carcinoma diagnosed as International Federation of Gynecology and Obstetrics (FIGO) stages Ⅰ and Ⅱ.Methods Three hundreds ninety-eight consecutive patients with clinical stage I,Ⅱ endometrial adenocarcinoma underwent primary surgical therapy between Oct.1990 to Oct.2010 were studied retrospectively to analyze the correlation between clinicopathological risk factors and the disease recurrence or prognosis.Results Thirty-six patients (9.0％,36/398) developed recurrence,21 of them (58.3％,21/36) relapsed within 5 years of treatment.The results shown that the disease recurrence were significantly associated with clinicopathological factors including:age [≤50 years versus ＞ 50 years,1.9％ (2/103) versus 11.5％ (34/295) ; P =0.004] ; histologic types [adenocarcinoma versus serous papillary adenocarcinoma,8.0％ (27/338) versus 6/14; P =0.000] ; tumor grade [grade 1,2 (7.4％,25/338) versus grade 3 (17.9％,10/56) ;P =0.022] ; depth of myometrial invasion [none (3.4％,2/59) versus ＜ 1/2 (7.5 ％,18/240) versus ≥ 1/2 (16.2％,16/99) ; P =0.011] ; tumor size [≤ 2 cm (5.9％,17/287) versus ＞ 2 cm (17.1％,19/111) ; P =0.000].peritoneal cytology [negative (6.9％,22/317) versus positive (23.8％,5/21) ;P =0.019] ;ER status[negative (20.8％,11/53) versus positive (5.5％,16/293) ; P =0.000] ; PR status [negative (30.0％,15/50) versus positive (4.1％,12/295) ; P =0.031].But lympho vascular space invasion (LVSI),p53 or PTEN status were not significant effect on recurrence and prognosis.Univariate analysis of survival indicated that age,histology,tumor grade,depth of myometrial invasion,tumor size,peritoneal cytology and PR status were correlated with overall survival(OS) and disease free survival (DFS ; all P ＜ 0.05),while ER status only impact on DFS (P ＜ 0.05).Conclusions The results showed that age,histologic type of carcinoma,myometrial invasion,tumor grade,peritoneal cytology,tumor size,ER and PR status are significant predictors for recurrence and prognosis of FIGO Ⅰ,Ⅱ stage endometrial carcinoma.Regular follow-up after treatment is essential for patients within 5 years.

Effect of a pilot intervention on setting up hospital-based neonatal resuscitation leading group in 12 hospitals in China / 中华围产医学杂志

Objective To evaluate the effect of a pilot intervention on setting up a hospital-based neonatal resuscitation leading group in 12 hospitals. Methods One provincial-level, two prefecturelevel and one county-level hospitals in Jiangxi, Liaoning and Hunan province were selected to participate in the intervention. A neonatal resuscitation leading group was set up in each hospital to investigate the mode of resuscitation practice training and re-training, improve and carry on the cooperation between obstetricians and pediatricians, record the steps of neonatal resuscitation of asphyxia cases and lead the exploration of the problems occurred during the process in their own hospital. The changes of asphyxia incidence and neonatal resuscitation process were analyzed to evaluate the effect of the intervention. Results (1) Incidence of neonatal asphyxia during intervention period: 315 neonatal asphyxia cases were recorded, among which 89.5 % (n = 282) were mild and 10. 5% (n=33) cases were severe asphyxia. The mean one-minute Apgar score was the lowest in county-level hospitals (5. 40±1.56), followed by provincial-level hospitals (5.63 ±1.67)and prefecture-level hospitals (6.03 ± 1.41). (2) Resuscitation was not performed according to the guidelines in 47. 9% (151/315) of asphyxia cases. Bag and mask ventilation was not performed according to guideline in 36. 5% (115/315) of cases. (3) Changes of asphyxia incidence after the intervention: the incidence of asphyxia in provincial-level (4.23 % vs 2.66 %, χ2 = 5. 021, P＜0.05)and prefecture-level (2.83% vs 1.67%, χ2 = 4. 948, P＜0.05) hospitals decreased significantly after the intervention. The incidence of severe asphyxia in both provincial-level (χ2 =3. 001, P＞0.05) and prefecture-level (χ2= 0. 966, P＞ 0. 05) hospitals decreased with no statistical significance. The asphyxia incidence in county-level hospitals decreased from 2. 48% to 1. 22% (χ2 = 2. 989, P =0. 084). The incidence of severe asphyxia in county-level hospitals decreased from 0.39% to 0. 00%(χ2=2. 567, P= 0. 035). Conclusions Setting up a hospital-based neonatal resuscitation leading group is an effective method to strengthen resuscitation practice training, promote the cooperation between departments, improve the level of neonatal resuscitation practice and therefore decrease the incidence of neonatal asphyxia in the hospital.
