Objective : To analyze the clinical characteristics of patients with adenomyosis (AM) and endometrial cancer (EC) and their role in preoperative diagnosis. Methods : A total of 142 patients with AM complicated with EC or endometrial atypical hyperplasia (EAH) and AM with abnormal uterine bleeding ( AUB) during the same period were collected from this hospital. They were divided into AM with EC or EAH group (71 cases) and control group (71 cases) according to whether they were complicated with EC or EAH. The clinical data of the patients were retrospectively analyzed , and the clinical characteristics and treatment strategies of the patients with adenomyosis complicated with endometrial cancer were discussed. Results : Univariate analysis showed that age , increased proportion of CA125 and CA125 , uterine volume , proportion of hypertension and abnormal endometrial ultrasonography in patients with AM with EC or EAH were significantly higher than those in the control group , and the proportion of dysmenorrhea was significantly lower than that in the control group , and the difference was statistically significant (P < 0. 05) . Multivariate Logistic regression analysis showed that endometrial thickening , endometrial echogenicity , and endometrial thickening combined with echogenicity were independent risk factors for AM with EC or EAH. Conclusion In clinical practice , the patients with AM with endometrial thickening or uneven echo - echo of ultrasound should be treated by hysteroscopy and curettage before further operation plan is formulated , so as to achieve the purpose of early diagnosis and treatment of EC.

Objective To investigate the value of using gonadotropin-releasing hormone agonist (GnRH-a) pretreatment in adenomyosis patients before adenomyomectomy. Methods From May 2012 to September 2015, 87 patients with adenomyosis who were non-effective to conservative therapy in Renmin Hospital of Wuhan University were enrolled in this study. According to the principle of randomized control, 41 patients were in the treatment group who were treated with GnRH-a 2-3 cycles before adenomyomectomy, while 46 patients in the control group. The control group paients were operated without any pretreatments. The blood loss, the number of penetrating into uterine cavity, duration of operation, duation of peritoneal drainage and the amount of drainage fluid, the difference of hemoglobin value before and after operation, total white blood cell count, duration of hospitalization, the maximum diameter of uterus and other indicators between the two groups were compared. Results In the treatment group, before and after treatment with GnRH-a, the uterus size, blood hemoglobinand CA125 value were statistically different (all P<0.05);between the treatment group of GnRH-a treated for 2 cycles and for 3 cycles, there were statistical differences of blood hemoglobin value [(108 ± 20) versus (118 ± 24) g/L], CA125 value [(26 ± 11) versus(19 ± 4) kU/L; all P<0.05]. There were statistical differences of blood loss in operation [(113 ± 32) versus (194 ± 42) ml], ratio of penetrating into uterine cavity [12%(5/41) versus 12%(8/46)], duration of operation[(79±23) versus (91±25) minutes], duration of peritoneal drainage after operation [(2.1±0.9) versus (3.0±1.2) days] and the amount of drainage fluid [(152±43) versus (232±32) ml], the difference of hemoglobin value before and after surgery [(-15.6±2.9) versus (-23.7±3.5) g/L], white blood cell count after 2-3 days of operation [(11.4±4.2)×109/L versus (13.5 ± 3.2) × 109/L], ratio of peri-operative blood transfusion [5% (2/41) versus 20% (9/46)] and duration of hospitalization [(11.2±1.9) versus (13.6±3.1) days] between the treatment group and the control group (all P<0.05). Conclusion The pretreatment of using GnRH-a before adenomyomectomy in adenomyosis patients has benefits for implementation of surgery and reducing peri-operative and postoperative complications.

A total of 296 patients were randomly divided into short message group (n =153) and non short message group (n =143).The former group received short message service (SMS) for follow-ups while the latter group had routine oral follow-ups.The return visit rate,recall rate of glycosylated hemoglobin (HbA1c),HbAlc level and glucose control rate for diabetics were assessed after one-year follow-up.The return visit rate (96％) and recall rate of HbAlc (78％) in the short message group were significantly higher than those in the non-short message group (59％,25％,P ＜0.01 for both).The HbAlc level after one-year follow-up (6.51 ± 0.74) ％ was lower than that one year before (6.85 ± 1.26) ％ in the short message group.The glucose control rate after one year (82％) were significantly higher than that one year before in the short message group (65％) and that after one year in the non-short message group(59％,P ＜ 0.01).Use of SMS platform system for follow-ups and health education can effectively improve the return visit rate and glucose control rate,lower the HbA1c level.in diabetics.

Objective To compare the influence of postoperative pelvic floor function after different surgical procedures of hysterectomy. Methods A total of 260 patients who underwent hysterectomy in Renmin hospital of Wuhan University from January 2012 to January 2014 were enrolled in the study, and divided into 5 groups by different surgical procedures, which were total abdominal hysterectomy (A-TH;46 cases), total laparoscopic hysterectomy (L-TH;59 cases), total vaginal hysterectomy (V-TH;42 cases), abdominal intrafascial hysterectomy (A-CISH;78 cases), laparoscopic intrafascial hysterectomy (L-CISH;35 cases). Pelvic examination, pelvic organ prolapse quantitation (POP-Q), test of pelvic muscle strength, pelvic floor distress inventory-short form 20 (PFDI-20) and the female sexual function index (FSFI) questionnaire were measured after 6 months and 12 months. Results The differences of pelvic organ prolapse incidence after 6 months, A-TH and A-CISH [7%(3/46) versus 3%(2/78)], A-TH and L-CISH [7%(3/46) versus 3% (1/35)] were statistically significance (all P＜0.05).POP-Q grade after 6 months between A-TH and A-CISH was statistically different in degree (P＜0.05). The differences of incidence of abnormal pelvic floor muscle fatigue after 6 months of A-TH and A-CISH [59% (27/46) versus 29% (23/78)], A-TH and L-CISH [59%(27/46) versus 26%(9/35)] were statistically significant (all P＜0.05), after 12 months the difference of L-TH and A-CISH [61% (36/59) versus 29%(23/78)] was statistically different (P＜0.05). The differences of incidence of abnormal pelvic floor muscle strength after 6 months of L-TH and A-CISH [53%(31/59) verus 24%(19/78)], V-TH and A-CISH [60%(25/42) verus 24%(19/78)], V-TH and L-CISH [60%(25/42) verus 23%(8/35)] were statistically significant (all P＜0.05);after 12 months the difference of V-TH and A-CISH [57% (24/42) versus 26% (20/78)] was statistically significant (P＜0.05). Stress urinary incontinence, abnormal bowel movements after 6 months and 12 months were no significant difference between groups (all P＞0.05), PFDI-20 total score was not statistically significant (P＞0.05). FSFI total score after 6 months and 12 months in A-TH and A-CISH, L-TH and A-CISH, A-CISH and L-CISH were statistically significant (all P＜0.05). Conclusion The influences of different surgical procedures to pelvic floor function are no statistical difference; as to the surgical resection of hysterectomy, intrafascia hysterectomy compared with extrafascia hysterectomy, the former is more helpful to the protection of the structure and function of the pelvic floor.

Objective: The main ingredients and the inhibitory effects of essential oil of a compound Chinese herbal medicine Weiqi Decoction (WQD) on AGS cell proliferation were to be investigated. Methods: Chemical compounds of WQD essential oil were detected by gas chromatography and mass spectrometry analysis. Cell viability was measured by methyl thiazolyl tetrazolium method. Cell cycle distribution was detected by flow cytometry. Apoptosis and necrosis of AGS cells were determined by Hoechst 33342/propidium iodine staining. Results: Chemical analysis showed that the main ingredients of WQD essential oil were bornylene and 3-n-butylphthalide. Ligustilide, which is the effective compound of Danggui (Radix Angelicae Sinensis), was not detected in WQD essential oil. The essential oil inhibited cell proliferation in a dose- and time-dependent manner, and blocked cell cycle progression at G(2)/M stage. At the concentrations that resulted in significant inhibition of cell proliferation and cell cycle arrest, essential oil induced both apoptosis and necrosis. Conclusion: The results suggest that WQD essential oil contains some effective ingredients for treating chronic atrophic gastritis and functional dyspepsia, and also has an antiproliferative effect on AGS cells through cell cycle arrest and apoptosis promotion in vitro. Therefore, essential oil should be retained as much as possible during stewing this decoction.

Objective The objective of this study was to investigate the clinical value of serum microRNA in predicting chemotherapy efficacy in patients with nasopharyngeal carcinoma. Methods A total of 187 patients with nasopharyngeal carcinoma who received cisplatin combined chemotherapy were enrolled in our hospital from January 2010 to December 2016,including 123 pa-tients with chemotherapy sensitivity and 64 patients with chemotherapy resistance. The serum levels of miRNA before the initial chem-otherapy were measured,the efficacy and predictive value of serum miRNA in nasopharyngeal carcinoma patients were evaluated using healthy subjects as controls. Results Serum level of miR-127 in nasopharyngeal carcinoma patients was significantly higher than that in healthy controls(4. 3 ± 1. 6 vs. 1. 4 ± 0. 5,P<0. 001). Serum level of miR-127 was significantly higher in chemotherapy-resistant patients than that in chemotherapy-sensitive patients(4. 5 ± 1. 3 vs. 3. 8 ± 1. 7,P<0. 001). The ROC curve showed that the predictive value of serum miR-127 for chemotherapy resistance in nasopharyngeal carcinoma patients was 0. 702(P<0. 001), with the optimal cut-off value of 4. 2,sensitivity of 82. 3% and specificity of 76. 3% . Compared with the chemotherapy-sensitive group,the proportion of patients with T3-4 ,N3 and TNM Ⅲ~Ⅳ in the chemotherapy-resistant group was significantly increased(P<0. 01),and the proportion of miR-127≥4. 2 was also increased(P<0. 001). Multivariate logistic regression analysis showed that TNM staging(OR=1. 655,95% CI:1. 142~2. 584,P=0. 016)and serum miR-127≥4. 2(OR=2. 231,95% CI:1. 762~4. 503,P=0. 001)were independent risk factors affecting chemotherapy resistance in nasopharyngeal carcinoma patients. Conclusion The el-evated serum level of miR-127 is an important risk factor for predicting chemotherapy resistance in patients with nasopharyngeal car-cinoma.

Objective : To explore the spatial distribution of occupational diseases in Guangdong Province and to provide evidence for the policy development of occupational disease prevention and control. Methods : A database of occupational disease incidence from 2009 to 2016 in Guangdong Province was built. The distribution of occupational diseases in Guangdong Province was displayed based on the geographic information system（GIS）, then spatial autocorrelation analysis and trend-surface analysis were carried out to explore the clustering areas and spatial epidemic characteristics of occupational diseases in Guangdong Province. Results : The number of cases with occupational diseases was 5 231 and was increasing year by year from 2009 to 2016 in Guangdong Province. The high-incidence areas were located in Guangzhou,Shenzhen,Foshan and Dongguan. Through global spatial autocorrelation analysis,it was found that there were spatial clustering of occupational diseases in Guangdong Province in each year（P<0.05）,and the cumulative incidence was also clustered（Moran's I=0.492,P<0.05）. The number of cases in Guangzhou,Shenzhen,Foshan and Dongguan had local spatial autocorrelation,and the local Moran's I values were 10.329,8.614,3.725 and 9.811,respectively（P<0.05）. The results of trend surface analysis showed that the overall incidence of occupational disease had a slight increase from west to east,and the Pearl River Delta region was a high-incidence area. Conclusion The incidence of occupational diseases in Guangdong Province had an obvious spatial clustering,the Pearl River Delta region was a high-incidence area.

Objective:To apply CBL combined with PBL based on SMART (specific, measurable, attainable, relevant and time-based) principle in nursing practice teaching in radiotherapy.Methods:A total of 100 nurses who performed nursing practice in the Department of Radiotherapy in Guangdong Provincial Hospital of Traditional Chinese Medicine from May 2016 to May 2020 were selected as the research objects. They were divided into a control group and a study group according to their admissions, with 50 people in each group. The study group used CBL combined with PBL teaching based on SMART principle, and the control group used traditional practice teaching. After the clinical practice, the two groups were assessed on theoretical and clinical practice skills, and the two groups' teaching satisfaction and teaching effects were evaluated through seminars and questionnaire surveys. SPSS 22.0 was used for t test and chi-square test. Results:The theoretical and clinical practice performance assessment scores of the practical nurses in the study group were higher than those in the control group, with statistically significant differences ( P<0.001). The teaching satisfaction rate of the practice nurses in the control group was 62.00% (31/50), and that of the practice nurses in the study group was 96.00% (48/50), with significant differences ( P<0.001). In terms of improving independent learning ability, information acquisition and problem analysis ability, improving clinical thinking ability, mobilizing learning enthusiasm, enhancing teamwork ability, nurse-patient communication ability, and recognition of innovation ability, the teaching satisfaction of the research group was higher than that of the control group.
