BACKGROUND:Previous research has shown that stem cells at different age stages had various proliferation and differentiation in vitro.Therefore,biological characteristics of bone marrow-derived mesenchymal stem cells at different age stages play a key role in evaluating differentiation into myocardial cells and determining proliferation and differentiation parameters in vitro.OBJECTIVE:To compare in vitro proliferation,surface marking,and differentiation into myocardial cells of bone marrow-derived mesenchymal stem cells from different aged rats.DESIGN,TIME AND SETTING:An in vitro contrast cytological observation was performed at the Laboratory of Biochemistry and Molecular Biology,Shanxi Medical University from May 2008 to May 2009.MATERIALS:A total of 15 healthy male Wistar rats were divided into three groups:1-month-old,3-month-old,and 12-month-old groups,with 5 rats in each group.METHODS:Bone marrow-derived mesenchymal stem cells were cultured using adherence screening method.At the third passage,cells differentiated into myocardium-like cells by the induction of 5-azacytidine.MAIN OUTCOME MEASURES:Cell proliferation was observed using MTT;cell surface marking was detected using flow cytometry;cardiac-specific myosin heavy chain mRNA expression was measured using RT-PCR.RESULTS:Bone marrow-derived mesenchymal stem cells were adherent in each group,and the proliferation curve was similar to each other.Under the same culture condition,the proliferation in the 1-month-old and 3-month-old groups was faster than 12-month-old group (F=28.71,P ＜ 0.05).The third-passage cells strongly expressed CD44 and CD71 but weakly expressed CD34 and CD45.At 2 weeks after 5-azacytidine induction,cardiac-specific myosin heavy chain mRNA was observed in all groups;however,the cardiac-specific myosin heavy chain mRNA expression in both 1-month-old and 3-month-old groups was significantly greater than 12-month-old group (t=5.140,2.827,P ＜ 0.05).CONCLUSION:With the age increasing of rats,proliferation,survival time,and differentiation of bone marrow-derived mesenchymal stem cells were weakened.

Objective To analyze prophylactic chemotherapy outcome and clinical characteristics in patients of high-risk hydatidiform mole. Methods Twenty-three patients who were diagnosed as high-risk hydatidiform mole and undergone prophylactic chemotherapy in our hospital were retrospectively analyzed.After prophylactic chemotherapy, 11 patients didn't develop to gestational trophoblastic neoplasia (GTN),while the other 12 patients developed to GTN and needed a regimen change to combination chemotherapy.The clinical characteristics of these patients and outcome of prophylactic chemotherapy were compared between two groups. Results There was no significant difference between the two groups on patients' age,weeks of delayed menses, enlarged uterine size excessive for gestational age, and incidence of theca-lutein cysts of ovaries. However,the median levels of pre-evacuation serum β-hCG in two groups were 469 144 U/L and 768 044 U/L respectively, and median days needed for β-hCG declining to normal(≤2U/L) at the first time were 71 and 120 days respectively, which were both significantly different between two groups.Analyzed with receiver operating charactristic(ROC), the level of serum β-hCG could be a predictor for prognosis. Choosing 750 000 U/L as the cut-off value, we could expect the serum β-hCG to have a specificity of 91% and a sensitivity of 58% to predict whether prophylactic chemotherapy will be successful.Conclusions For those patients who have to receive prophylactic chemotherapy because of risk factors and unavailable hCG assessments for follow-up, it's better to use double-agent or combination chemotherapy if the level of serum β-hCG reached 750 000 U/L so as to reduce therapy duration and prevent relevant chemoresistance.

Objective To analyze and compare the clinical characteristics and the treatment outcome of the patients with chemo-resistant and relapsed gestational trophoblastic neoplasia (GTN).Methods The clinical records of the patients with refractory GTN treated at the Peking Union Medical College Hospital (PUMCH) from Jan 2005 to Dec 2007 were retrospectively reviewed.According to the reasons for referral, all cases were classified as chemo-resistant GTN group who had never a normal serum human chorionic gonadotropin-beta subunit (β-hCG) level during their previous treatment, relapsed GTN group who had elevated serum β-hCG levels in the absence of the pregnancy after finished treatment 3 months or more, and undetermined GTN group who had elevated serum β-hCG levels in the absence of the pregnancy less than 3 months after completed treatment.The clinical features and treatment outcomes were compared between undetermined GTN group and chemo-resistant GTN group and also between undetermined GTN group and relapsed GTN group, respectively.Results Of 81 patients with refractory GTN, 32 cases were defined as undetermined GTN, 38 cases as chemo-resistant GTN and 11 cases as relapsed GTN.The median number of previous chemotherapy regimens, the rate of serologic complete remission ( SCR), the patients who needed to change regimens due to resistance, and the patients who needed to change regimens in the undetermined GTN group and the chemo-resistant GTN group were 2.3 versus 3.1 ( P = 0.010),100% (32/32) versus 66% (25/38, P ＜ 0.01 ), 22% (7/32) versus 58% (22/38, P = 0.002) and 28% (9/32) versus 63% (24/38, P = 0.003 ), respectively.No significant difference were observed between undetermined GTN group and relapsed GTN group in clinical features, previous and current treatment or treatment outcome ( all P ＞0.05 ).Conclusions In order to evaluate accurately the treatment outcome of refractory GTN, it seems more appropriate for the patients who had reached the normal value of serum β-hCG when completed treatment to be defined as patients with relapsed GTN, while whose serum β-hCG levels elevated in the absence of the pregnancy after the completion of treatment, irrespectively of duration of stopping treatment.Comparing with the patients with chemo-resistant GTN, the outcome of patients with relapsed GTN is better.

Objective To investigate the correlation between the types of constitution in TCM and the sleep status in the PLA Navy divers. Methods Eighty-nine PLA Navy divers who performed 10m diving professional training were selected. Constitution in TCM was classified and determined by the standardized standard Constitution in Chinese Medicine Questionnaire, sleep status was evaluated by the Pittsburgh Sleep Quality Index. Results 62.9% of Navy divers were the mild constitution in TCM. The eight kinds of the biased constitution in TCM are ranked with yang deficiency, phlegm-dampness, dampness-heat, qi deficiency, yin deficiency, blood stasis, qi stagnation and special intrinsic quality. Among 78 Navy divers with good sleep quality, there were 49 divers (72.1%) with the mild constitution in TCM and 19 (27.9%) with the biased constitution in TCM. Among 21 Navy divers with poor sleep quality, there were 7 divers (33.3%) with the mild constitution in TCM (accounting for) and 14 (66.7%) with the biased constitution in TCM. For Navy divers with poor sleep quality, the sleep quality scores were positive correlated with the blood stasis constitution in TCM (r=0.481,P<0.05). Conclusion Sleep status is correlated with the types of the constitution in TCM, and regulating constitution in TCM can improve sleep quality in PLA Navy divers.

Objective:To explore the effect of combining motor imagery therapy (MIT) with kinesio taping in rehabilitating the upper limb motor function of stroke survivors.Methods:Ninety-two stroke survivors were randomized into a control group ( n=31), an MIT group ( n=31), and a combination group ( n=30). All were given 40 minutes of basic rehabilitation therapy daily, while the MIT group received additional MIT therapy, and the combination group received kinesio taping with the MIT therapy. The taping was applied according to a patient′s condition and changed every other day. The MIT was conducted twice a day. The experiment lasted 8 weeks, six days a week. Before and after the 8 weeks, the upper limb functioning, ability in the activities of daily living and muscle tension of each subject were assessed using the Fugl-Meyer assessment for the upper extremities (FMA-UE), the Hong Kong version of the functional test for a hemiplegic upper extremity (FTHUE-HK), the modified Barthel index (MBI) and the modified Ashworth scale (MAS). Results:The average post-treatment FMA-UE and MBI scores of the combination group were significantly higher than those of the MIT group, and both were significantly higher than the control group′s averages. The average FTHUE-HK grading of the combination group and MIT group after the treatment was significantly higher than in the control group, with that of the combination group significantly superior to the MIT group′s average. After the intervention the average MAS rating of the combination group was significantly lower than that of the control group.Conclusion:MIT combined with Kinesio taping can significantly improve the upper limb motor functioning of stroke survivors, and significantly reduce their abnormal muscle tone compared to traditional treatments.

Objective:To introduce the technical essentials of cytoreduction surgery (CRS) with extensive peritonectomy （“rolling carpet” surgery） in stage Ⅲc epithelial ovarian cancer (EOC) and evaluate the feasibility and safety of the operation by analyzing the incidence of surgical complications and perioperative mortality.Methods:From December 2017 to December 2019, 30 patients with stage IIIc EOC who underwent “rolled carpet” CRS and 30 patients who underwent traditional CRS at the same period in Sichuan Cancer Hospital were collected. To summarize the key points of “rolled carpet” CRS operation technology, i.e. the extraperitoneal space was the cut path of ovarian cancer operation, and the tumor in the pelvic cavity was dissociated from the extraperitoneal space of the pelvic cavity. The tumor in the pelvic cavity and all the implants or potential metastases on the parietal peritoneum were removed completely. The clinical and pathological characteristics between the two groups were analyzed retrospectively, and the feasibility and safety of “rolling carpet” CRS were evaluated by comparing the operation related indexes and the occurrence of surgical complications between the two groups.Results:(1) Clinicopathological features: the age of patients in “rolling carpet” CRS group and traditional CRS group were respectively (55.4±9.6) and (54.6±9.5) years, and the median peritoneal cancer index (PCI) was 12 (range, 4-24) and 10 (range, 5-18), respectively. There were no statistical significance between the two groups (all P>0.05). (2) Operation related indexes: in the “rolled carpet” CRS group, all patients （100%, 30/30） were performed optimal CRS, reaching completeness of cytoreduction score （CC score）, named CC-0 score, and there was no visible residual lesion after operation. While, in the traditional CRS group, 23 patients （77%, 23/30） reached CC-0 score, 5 cases （17%, 6/30） reached CC-1 score, 2 cases （7%, 2/30） reached CC-2 score, and there were statistical significance between the two groups ( P=0.011). The median surgical time was 315 minutes (range, 252-446 minutes) vs 268 minutes (range, 215-372 minutes), the median intraoperative blood loss was 589 ml (range, 300-900 ml) vs 450 ml (range, 250-800 ml), the median ICU hospital stay time was 2 days (range, 1-7 days) vs 1 day (range, 0-5 days), the median total hospital stay time was 14 days (range, 9-17 days) vs 12 days (range, 7-15 days). There were no statistical significance between the two groups (all P>0.05). (3) Surgical complications: there were respectively 5 cases (17%, 5/30) and 3 cases (10%, 3/30) complications with Clavien-Dindo grading Ⅰ-Ⅱ, which was significant no difference between the “rolled carpet” CRS group and the traditional CRS groups ( P>0.05). No re-operations were needed and the operative mortality was 0. Conclusion:It is safe and feasible to perform “rolled carpet” CRS in patients with advanced stage Ⅲc EOC with peritoneum implantation and metastasis, which could achieve optimal CRS, and has an acceptable incidence of perioperative complications, no perioperative death.

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.
