Objective To study the correlations between bone fracture types and healing time in patients with osteofluorosis. Methods Thirty-seven patients with osteefluorosis and long tubular bone fracture were diagnosed in accordance with radiogram retrospectively. The fractures were divided into two groups: sclerotic and osteoporotic. Twenty four fractured patients with non osteofluorosis were included in the study as controls. All of the patients had operation(open reduction and nickelclad internal fixation). Fracture healing in patients with sclerotic and osteoporotic groups was compared with the control group after operation. Results There were notable differenees(F=4.30,P< 0.05) in term of fracture healing time among the three groups [sclerotic group:(18.4±5.3)weeks; osteoporotic group: (24.5±5.1)weeks; control group: (17.6±3.8)weeks]. Notably, there were significant differences between the osteoporotic and control groups(q=2.34,P<0.05), and between sclerotic and osteoporotic gronps(q=2.51, P<0.05). The healing time of the osteoporotic group was longer than that of sclerotic group. The constituent ratios of fracture healing in sclerotic, osteoporotic and control groups were 73.1% (19/26) ,54.5% (6/11),75.0% (18/24) respectively, and the differences among the three groups were statistically significant(X2=3.67,P<0.05). The healing rate of the osteoporotic group was lower than that of sclerotic and control groups(X2=3.12, 3.36, all P< 0.05). The constituent ratios of healing in the sclerotic, osteoporotic and control groups were 26.9% (7/26),45.5% (5/11),25.0%(6/24), respectively, and there differences among the three groups were statistically significant (X2=4.07 ,P<0.05). The delayed healing rate of the osteoperotic group was higher than those of the sclerotic and control groups(X2= 3.87,3.95, all P<0.05). Conclusions Fracture healing time of osteoporotic osteofluorosis after fracture is longer than normal, and the cause might be the loss of bone mass.

Objective:To explore the related factors of postoperative adjuvant therapy for cervical cancer stagedⅠB1-ⅡA2 [according to 2018 International Federation of Gynecology and Obstetrics (FIGO) staging standard], and to establish a nomogram model to predict the risk of postoperative adjuvant therapy for locally advanced cervical cancer.Methods:A total of 714 patients with cervical squamous cell cancer staged FIGO ⅠB1-ⅡA2 treated by surgery in Anhui Provincial Hospital were selected as the research objects from January 2009 to December 2019, and their clinicopathological data were analyzed. Multiple logistic regression analysis was used to determine the influencing factors, and a nomogram model was established to predict the risk of postoperative adjuvant treatment of cervical cancer. The predictive performance of the model was evaluated with the consistency index (C-index), and the compliance of the model was evaluated with the calibration curve.Results:Univariate analysis suggested that postoperative adjuvant therapy for cervical cancer was associated with gravidity ( χ2=11.506, P=0.001), underlying disease (hypertension or diabetes) ( χ2=7.668, P=0.006), squamous cell cancer antigen (SCC-AG) level ( χ2=19.392, P<0.001), imaging risk factors ( χ2=16.392, P<0.001), FIGO stage ( χ2=25.686, P<0.001), tumor size ( χ2=9.392, P=0.025) and surgical path ( χ2=16.590, P<0.001). Multivariate logistic regression analysis suggested that the number of pregnancy >2 times ( OR=1.951, 95% CI: 1.355-2.808, P<0.001), SCC-Ag &ge;1.5 μg/L ( OR=2.021, 95% CI: 1.444-2.829, P<0.001), FIGO stage ⅠB3-ⅡA2 [ⅠB3 ( OR=1.933, 95% CI: 1.139-3.282, P=0.015); ⅡA1 ( OR=2.723, 95% CI: 1.556-4.765, P<0.001); ⅡA2 ( OR=3.159, 95% CI: 1.502-6.646, P=0.002)], with underlying disease (hypertension or diabetes) ( OR=1.867, 95% CI: 1.051-3.318, P=0.033), imaging risk factors ( OR=1.997, 95% CI: 1.127-3.537, P=0.018), without neoadjuvant therapy [preoperative neoadjuvant therapy for 1 cycle ( OR=0.402, 95% CI: 0.207-0.783, P=0.007)] and laparoscopic surgery ( OR=2.177, 95% CI: 1.524-3.112, P<0.001) were independent influencing factors for postoperative adjuvant treatment of cervical cancer. Based on the screened variables, the nomogram model to predict the risk of postoperative adjuvant treatment for cervical cancer has good predictive performance (C-index was 0.702) and compliance. Conclusion:The number of pregnancy >2 times, SCC-Ag &ge;1.5 μg/L, FIGO stage ⅠB3-ⅡA2, with underlying disease (hypertension or diabetes), imaging risk factors, without neoadjuvant therapy, and laparoscopic surgery are independent influencing factors for postoperative adjuvant treatment of cervical cancer. A nomogram model has been constructed to predict the risk of postoperative adjuvant therapy for locally advanced cerrical cancer, and it can provide evidence for clinical treatment selection.

Objective To investigate the relationship between the expression of eonnexin 43 (Cx43) and clinicopathologieal characteristics of gastric cancer, and to study the role of Cx43 in peritoneal metastasis of gastric cancer. Methods Thirty-two patients who had gastric cancer and with peritoneal metastasis had been admitted to Southwest Hospital from January 2000 to December 2008. Gastric cancer tissues, adjacent tissues and metastatic peritoneal tissues were obtained postoperatively, and the expression of Cx43 was detected by immunohistochemistry. The relationship between Cx43 expression and clinicopathological characteristics of gastric cancer was analyzed. All data were analyzed via Spearman rank correlation coefficient, Fisher exact probability and chi-square test. Results The expression of Cx43 was mainly detected in the cell membrane and cytoplasm. The positive expres-sion rates of Cx43 in gastric cancer tissues, adjacent tissues and metastatic peritoneal tissues were 34% (11/32), 100% (32/32) and 94% (30/32), respectively. There were significant differences in the Cx43 expression between gastric cancer tissues and adjacent tissues (X~2=28.350, P < 0.01), and between gastric cancer tissues and metastatic peritoneal tissues (X~2 = 21.989, P < 0.01). The expression of Cx43 did not correlate with age and sex of patients (r = -0.030, - 0.169, P > 0.05), but with tumor differentiation, histological type and lymph node metastasis (r = 0.750, 0.642, - 0.357, P < 0.05). Conclusions There is a decreased expression of Cx43 in gastric cancer tissues and a up-regulated expression of Cx43 in metastatic peritoneal tissues. Cx43 may play a positive role in the peritoneal metastasis.

Objective To investigate clinical characteristics and emergency managements of postrenal acute renal failure(ARV)induced by melamine in infant.Method Fluid therapy for urine alkalization and hydration,cistoscope drainage and peritoneal dialysis step by step were exerted in those who had both a history of certain milk intake and ARF according to the definition of pediatric ARF which developed by Pediatric Nephrology Assembly of Chinese Pediatric Association in 1994.Results Thirty-four postrenal ARF cases with anuria due to melamine in Nanjing Children's Hospital of Nanjing Medical University were involved in the study.Seventy cases(50%)re-ceived fluid therapy only.Nine cases(26.5%)received fluid thempy and eistoscope drainagemand 4 cases (11.8%)received fluid therapy and cistoscope drainage and peritoneal dialysis.Four cases(11.8%)received ur-gent peritoneal dialysis due to severe hyperkalemia.All cases(100%)survived.The urine pH at the first day.the second day,and after the second day in those who just pass away urine were 6.1±1.0、6.5±0.7.5.3±0.4,respectively(F=4.563,P=0.026).Conclusions Fluid therapy for urine alkalization and hydration and stop sequential thempy are effective in infant with postrenal ARF induced by melamine.

Objective To investigate the expression of miR-30d in breast cancer tissues and demonstrate the regula-tive effects of miR-30d ASO on the invasion and migration of breast cancer cells in vitro. Methods The expression levels of miR-30d in 108 breast cancer tissues and their adjacent tissues were detected by real-time quantitative PCR method. Af-ter transfection with miR-30d ASO, the biological effects of miR-30d on in breast cancer cells was measured by transwell as-say and wound healing assay. The expressions of matrix metalloproteinase (MMP)-2 and MMP-9 were analyzed by Western blot assay. Results The expression level of miR-30d was found to be over-expressed in breast cancer tissues(P<0.05). Compared with control group and nonsense interference group, the miR-30d expression was significantly decreased in breast cancer cells(transfection with miR-30d ASO). Results of transwell and wound healing assay showed that the invasion and mi-gration ability decreased significantly after transfection with miR-30d ASO, and expressions of MMP-2 and MMP-9 were down-regulated (P<0.05). Conclusion miR-30d was over-expressed in human breast cancer. The invasion and migration of breast cancer cells can be effectively inhibited by decreasing the expression of miR-30d. miR-30d may become a new tar-get for the regulation of invasion and migration in breast cancer.

Objective To evaluate the effectiveness of intravenous immunoglobulin (IVIG) in critical hand-foot-mouth disease (HFMD).Methods The data from PubMed, MEDLINE, EMBASE, EBSChost, Cochrane Library, Cochrane Central Register of Controlled Trials, Ovid, China Biology Medicine disc, Wanfang Data, China National Knowledge Infrastructure, Chinese Citation Database, and other references and grey literatures were retrieved, screening out all those related to clinical trials on treating critical HFMD by IVIG.Standard methods of the Cochrane Collaboration were employed to evaluate the methodological quality of the trials.Meta analysis was performed with Rev man 5.3 software.Results Eleven trials including 967 cases were investigated.The meta analysis showed that IVIG had significantly clinical efficacy (OR =6.84,95％ CI:3.74-12.52 ,P ＜ 0.05).IVIG could significantly decrease duration of fever (MD =-1.94,95％ CI:-3.07--0.81 ,P ＜0.05) ,hospitalization time (MD =-4.56,95％ CI:-8.95--0.17,P ＜0.05).There was no significant difference in duration of fever (MD =-0.28,95 ％ CI:-0.59-0.03, P ＞ 0.05), duration of herpes (MD =0.18,95％ CI:-0.22-0.59, P ＞ 0.05), hospitalization time (MD =-0.12,95％ CI:-0.47-0.23, P ＞ 0.05) when the dosage of injection was adjusted.Conclusions IVIG is recommended for treating critical HFMD because it is effective in decreasing the duration of fever and hospitalization.Well designed studies with more sample in multi-center are required in further study to explore the efficacy and safety of IVIG on critical HFMD.
