Objective To study the influence of survivin mutant-T34A ( survivinT34A) and survivin deletant-N-terminal 8 amino acids residues ( survivinN-8AA ) on the cell cycle distribution and chemosensitivity in human ovarian cancer HO-8910 cells for explorating the roles of modified survivin-mediated apoptosis induced by chemotherapeutic agents and possible signaling pathways involved. Methods pcDNA3.1 plasmid contained wild-type, survivinT34A and survivinN-8AA genes were transfected into HO-8910 cells,respectively, the control groups were HO-8910 cells transfected with pcDNA3. 1 plasmids. The expression of mRNA was examined by reverse transcription(RT) PCR and identified by DNA sequencing; the cell cycles were determined by flow cytometer analysis ( FCM ); the growth inhibitions rate of cisplatin ( DDP),paclitaxel (PTX) and LY294002 on the transfected cells were determined using methyl thiazolyl tetrazolium (MTT) assay. Results (1) The RT-PCR procedures and genome sequences showed that the survivin mRNA were expressed stable in the transfected HO-8910 cells. (2) There was lower percent of G0/G1 phase cells in SN-HO-8910 cells than that in PC-HO-8910 cells (44. 72% vs. 49.64%, P <0. 05) ;while higher percentage of G2/M phase and S phase cells( 1.06% and 54. 22% vs. 0. 56% and 49. 80%, P < 0. 05 ).There was lower the G2/M phase and S phase cells in M-HO-8910 cells 0. 16% and 36. 33%, than that in PC-HO-8910 cells( P < 0. 05 ); while higher percentage of G0/G1 phase cells(63. 51% ,P < 0. 05 ). G0/G1 ,G2/M and S phase cells in Sur-HO-8910 cells were 54. 46%, 0. 62% and 44. 92%, and there were not significantly difference ( P > 0. 05 ), compared to those in PC-HO-8910 cells. ( 3 ) The inhibitory concentration ( IC50 ) of DDP and PTX were higher in Sur-HO-8910 cells than those in control cells [(20. 4 ±6. 1)vs. (14.4 ±3.9)μmol/L,(36.7 ±4.0) vs. (28.6 ±3.6) μmol/L;all P<0.05]. The IC50 of DDP and LY294002 in SN-HO-8910 cells were lower than those in control cells[(7. 6 ± 1.0) vs. ( 14. 4 ± 3.9)μmol/L, ( 13.2 ± 4. 0) vs. (41.0 ± 7. 9 ) μmol/L; all P < 0. 01]. The IC50 of PTX [( 37. 9 ± 4. 8 ) μmol/L]in SN-HO-8910 cells were higher than that in control cells(P <0. 05). The IC50 of DDP in M-HO-8910 cells [(9.9 ± 1.2) μmol/L] were lower than that in control cells(P <0. 05) ,and the IC50 of LY294002 in M-HO-8910 cells [(66. 9 ± 4. 8) μ mol/L] higher than that in control cells ( P < 0. 01 ). Conclusions The changes of cells cycle distribution caused by survivinT34A or survivinN-8AA enhanced the G2/M cell cycle-dependent chemosensitivity of PTX. Compared to survivinT34A, survivinN-8AA preferentially to mediate the cytotoxicity of DDP and LY294002, suggesting that it may be related to the cell cycle-dependence of survivin function and to blockage of the formation of its active dimer.

Objective To evaluate the incidence and significance of perineural invasion (PNI) in cervical cancer. Methods Retrospective chart review of patients with cervical cancer (stages Ⅰa2-Ⅱb) who underwent radical hysterectomy and pelvic lymphadenectomy from 2007 to 2012. To evaluate the incidence and significance of PNI in cervical and uterine tissues by microscopic examination. Results A total of 238 patients were included, 9.2% (22/238) patients with PNI in the cervical stroma. Patients with PNI were more likely to have adverse histopathologic features, including lymphoma vascular space invasion, parametrical invasion, depth of invasion, tomor size and lymph nodes metastases (all P<0.05). PNI were independent of age, international federation of gynecology and obstetrics (FIGO) stage, histopathology type and grade, and positive vaginal margin (all P>0.05). Patients with PNI had shorter disease-free and overall survival (P=0.002 and P=0.008, respectively). On multivariate analysis, risk factors for recurrence and death included parametrical invasion and depth of invasion (P<0.05). Similarly, risk factors for recurrence included lymph nodes metastases (P=0.024). However, PNI was not identified as an independent risk factor for either recurrence or death (P>0.05). Conclusions PNI exists in early cervical cancer. PNI is associated with tumor size, depth of invasion, parametrical invasion, lymphoma vascular space invasion and lymph nodes metastases. PNI represente a decreasing disease-free and overall survival in patients with early-stage cervical cancer, and is independently associated with multiple high-risk factors, which be informed management decisions regarding adjuvant therapy.

Objective: To observe the relationship between the dynamic changes of plasma levels of urotensin II (UII) and the stability of coronary atherosclerotic plaque in patients with acute coronary syndrome (ACS).
Methods: Our research included 2 groups: ACS group,n=135 consecutive patients treated in our hospital from 2013-03 to 2013-08 that including unstable angina pectoris (UAP) sub-group,n=7, non-ST segment elevation myocardial infarction (NSTEMI) sub-group,n=22 and STEMI sub-group,n=106. In addition, there was a Control group,n=48 healthy subjects. Plasma levels of UII, hs-CRP and NT-proBNP were examined and compared among different groups at different time points.
Results: Compared with Control group at immediate admission, ACS group had increased plasma level of UII (39.82 ± 22.28) pg/ml vs (26.88 ± 6.09) pg/ml,P<0.001; UII level in STEMI sub-group was lower than NSTEMI sub-group (37.41 ± 22.74) pg/ml vs (48.07 ± 15.82) pg/ml,t=2.092,P <0.05. In ACS patients, UII had no correlation to hs-CRP (r=0.041, P=0.639) and NT-proBNP (r=0.112,P=0.261) at immediate admission. There were 58 ACS patients finished the 3 months follow-up study and their UII level was increased than immediate admission as (56.52 ± 20.70) pg/ml vs (51.58 ± 18.70) pg/ml,t=-2.366,P<0.05.
Conclusion: Plasma levels of UII have been changing in different type of ACS patients at immediate admission, UII presented decreasing trend from UAP to NSTEMI to STEMI, while it had increasing trend upon stabilized condition; the admission level of UII had no correlation to inflammatory marker hs-CRP and ventricular overload marker NT-proBNP. UII is not only related to the extent of atherosclerosis, but also related to the nature of atherosclerosis or the stability of plaques.

Objective To make comparison of duration of subarachnoid block with intrathecal ropivacaine between gravidas with diabetes mellitus and non-diabetic pregnancy, to evaluate the sensitivity of parturient with diabetes to ropivacaine. Methods 75 parturients who were presenting for elective cesarean section were randomly divided into pregestational diabetes mellitus group (group P, n=15) , gestational diabetes mellitus group (group G, n=30) and non-diabetic parturients group (group N, n=30). After entering the operating room, parturients were given spinal anesthesia spinal at the L3~4 interspace with 0.5% hyperbaric ropivacaine 3 ml with left lateral decubitus position. To determine the level of sensory block by 10 g monofilament and evaluate the motor block with modified Bromage score. To record the time T6 sensory level was obtained, the onset time of sensory block, motor block, the duration of the motor block and sensory block. Results The time T6 sensory level was obtained of Group P were significantly shortened (P < 0.001). Compared with Group N and Group G, the duration of sensory (P < 0.001) and motor (P < 0.001) block were significantly prolonged. Conclusion Parturients with pregestational diabetes mellitus are more sensitive to 0.5% hyperbaric ropivacaine compared to non-diabetic parturients. Compared with non-diabetic parturients, there are no difference in the sensitivity of parturient with gestational diabetes mellitus to 0.5%hyperbaric ropivacaine.

Background:
The impact of para-aortic lymphadenectomy (PALD) on prognosis and quality of life (QoL) for IB2-IIA2 cervical cancer patients remain controversial. And whether intraoperative frozen pathology exam on common iliac lymph nodes could help predict para-aortic lymph node (PALN) metastasis was unanswered with high-level evidence.
Methods
A multi-center, randomized controlled study is intended to investigate the effect of PALD on the prognosis and QoL in cervical cancer patients and to assess the value of intraoperative frozen pathological evaluation of common iliac nodes metastasis for the prediction of PALN metastasis. After choosing whether to receive intraoperative frozen pathological examination of bilateral common iliac lymph nodes, eligible patients will be randomly assigned (1:1) to receive PALD or not. The primary end point is 2-year progression-free survival (PFS). The secondary end points include 5-year PFS, 2-year overall survival (OS), 5-year OS, adverse events (AEs) caused by PALD, AEs caused by radiotherapy and QoL. A total of 728 patients will be enrolled from 8 hospitals in China within 3-year period and followed up for 5 years.

Objective:The real-world clinical data of patients with newly diagnosed ovarian cancer (including fallopian tube cancer and primary peritoneal cancer) who received first-line maintenance therapy with poly adenosine diphosphate ribose polymerase inhibitor (PARPi) were retrospectively analyzed, and the prognostic factors were preliminarily explored.Methods:(1) The clinicopathological data and follow-up data of ovarian cancer patients treated with PARPi first-line maintenance therapy from August 2018 (PARPi was launched in China) to December 31, 2021 in Sichuan Cancer Hospital were collected (real-world clinical data). (2) According to the different types of PARPi, real-world clinical data were divided into olaparib group and niraparib group, which were respectively compared with the inclusion and exclusion criteria of representative domestic and foreign phase Ⅲ randomized controlled trials (RCT), including olaparib as first-line maintenance therapy for advanced ovarian cancer patients with BRCA1/2 gene mutation (SOLO-1 study), niraparib as first-line maintenance therapy (PRIMA study), and niraparib as first-line maintenance therapy for Chinese advanced ovarian cancer patients (PRIME study). (3) The prognosis of the two groups and the prognostic factors were analyzed.Results:(1) A total of 83 patients were included in this study, with a median age of 51 years (47-57 years), including 75 cases of ovarian cancer, 5 cases of fallopian tube cancer, and 3 cases of primary peritoneal cancer; 5 cases of stage Ⅰ, 9 cases of stage Ⅱ, 55 cases of stage Ⅲ, 12 cases of stage Ⅳ, and 2 cases of unknown stage; neoadjuvant chemotherapy (NACT) was performed in 40 cases and non-NACT in 43 cases; 62 cases had no visible residual lesion after surgery (R0), 9 cases had residual disease lesions <1 cm (R1), 8 cases had residual disease lesions ≥1 cm (R2), and 4 cases with unknown postoperative residual disease. Thirty-two cases had PARPi treatment interruption, 40 cases had PARPi reduction, and 1 case terminated treatment due to acute leukemia. Of the 83 patients, 35 were in the olaparib group and 48 were in the niraparib group. The proportion of patients with high-grade serous carcinoma (100% and 75%, respectively) and the proportion of BRCA mutant patients (91% and 10%, respectively) in the olaparib group were higher than those in the niraparib group (all P<0.01). (2) Compared with the inclusion and exclusion criteria of the SOLO-1 study, the olaparib group had only 60% (21/35) coincidence rate; compared with the inclusion and exclusion criteria of PRIMA and PRIME studies, the coincidence rates of niraparib group were only 31% (15/48) and 69% (33/48). The most common reasons for non-compliance were number of chemotherapy courses, histopathological type, and surgical pathological stage. (3) Of the 83 cases received first-line maintenance therapy with PARPi, the median follow-up was 15.9 months (11.3-22.9 months), the median progression-free survival (PFS) was 29.7 months (95% CI: 25.9-33.6 months), and the median overall survival was 49.8 months (95% CI: 47.4-52.2 months). Univariate analysis showed that unilateral or bilateral ovarian cancer, efficacy after platinum-containing chemotherapy, presence or absence of measurable lesions at the end of chemotherapy, and total number of chemotherapy courses were significantly associated with PFS (all P<0.05). Multivariate analysis showed that unilateral or bilateral ovarian cancer, total number of chemotherapy courses, and efficacy after platinum-containing chemotherapy were independent factors affecting PFS in stage Ⅱ-Ⅳ patients with PARPi first-line maintenance therapy (all P<0.05). Conclusions:Unilateral ovarian cancer, the total number of chemotherapy courses no more than 9, and achieving complete response after platinum-containing chemotherapy before maintenance therapy are independent influencing factors of PFS benefit in patients with PARPi first-line maintenance therapy. Due to the large differences between the patients in real clinical practice and the research subjects of phase Ⅲ RCT, the results of representative retrospective studies still have important clinical reference significance.
