Acute pancreatitis is a rare complication in postoperative colorectal cancer patients after FOLFOX6 (oxaliplatin + calcium folinate +5-FU [5-fluorouracil]) chemotherapy. In this paper, a total of 62 patients with gastrointestinal cancer were observed after the burst of acute pancreatitis. Surgery of the 62 cases of colorectal cancer patients was completed successfully. But when they underwent FOLFOX6 chemotherapy, five patients got acute pancreatitis (8.06%), four (6.45%) had mild acute pancreatitis, and one (1.61%) had severe acute pancreatitis, of which two were males (3.23%) and three females (4.84%). No patients (0.00%) had acute pancreatitis on the 1st day after chemotherapy; one patient (1.61%) got it in the first 2 and 3 days after chemotherapy; and three others (4.83%) got it in the first 4 days after chemotherapy. In the 62 patients with malignant tumors, the body mass index (BMI) was less than 18 (underweight) in six of them, with two cases of acute pancreatitis (33.33%); the BMI was 18–25 (normal weight) in 34 cases, with one case (2.94%) of acute pancreatitis; the BMI was 25–30 (overweight) in 13 cases, with 0 cases (0.00%) of acute pancreatitis; and the BMI was ≥30 (obese) in nine patients, with two cases of acute pancreatitis (22.22%). After symptomatic treatment, four patients were cured and one died; the mortality rate was 1.61%. Most of them appeared in the first 4 days after chemotherapy; the probability of this complication is significantly higher in slim and obese patients than in normal weight patients. Postoperative colorectal cancer patients after FOLFOX6 chemotherapy have a sudden onset of acute pancreatitis occult, especially in patients with severe acute pancreatitis; the symptoms are difficult to control, there is high mortality and it is worthy of clinician’s attention. © 2015 Ji et al.

Kinesin family member 14 (KIF14) is a member of kinesin family proteins which have been found to be dysregulated in various cancer types. However, the expression of KIF14 and its potential prognostic significance have not been investigated in cervical cancer. Real-time PCR was performed to assess the expression levels of KIF14in 47 pairs of cervical cancer tissues and their matched normal tissues from patients who had not been exposed to chemotherapy as well as tissue samples from 57 cervical cancer patients who are sensitive to paclitaxel treatment and 53 patients who are resistant. The association between KIF14 expression levels in tissue and clinicopathological features or chemosensitivity was examined. Kaplan-Meier analysis and Cox proportional hazards model were applied to assess the correlation between KIF14 expression levels and overall survival (OS) of cervical cancer patients. KIF14 expression levels were significantly increased in cervical cancer tissues compared with matched non-cancerous tissues and it was higher in tissues of patients who are chemoresistant compared with those who are chemosensitive. KIF14 expression was positively associated with high tumour stage (P=0.0044), lymph node metastasis (P=0.0034) and chemoresistance (P<0.0001). Kaplan-Meier analysis showed that high KIF14 expression levels predicted poor survival in patients with (P=0.0024) or without (P=0.0028) paclitaxel treatment. Multivariate analysis revealed that KIF14 was an independent prognostic factor for OS. Our study suggests that KIF14 may serve as a predictor of poor survival and a novel prognostic biomarker of chemoresistance to paclitaxel treatment in cervical cancer.

To investigate the morphological changes of meibomian glands in patients with type 2 diabetes mellitus (DM).Of 118 eyes (118 patients) with type 2 DM (DM group) and 100 eyes of 100 control subjects (control group) were enrolled. After completing an ocular surface disease index (OSDI) questionnaire, the non-invasive tear film break-up time (NI-BUT) and the structure of the meibomian glands (MGs, meibography) were assessed by the Keratograph 5M system. Partial or complete loss of MG was scored for each eyelid from grade 0 (no loss) to grade 3 (lost area was >2/3 of the total MG area), which were also examined by laser scanning confocal microscopy (LSCM). The primary outcomes were meibomian gland acinar unit density (MGAUD), meibomian gland acinar longest diameter (MGALD) and meibomian gland acinar shortest diameter (MGASD).Compared with control group, the OSDI was significantly higher in DM group (Compared with the normal control participants, the patients with type 2 DM had more unstable tear films and severe symptoms of dry eye. Using Keratograph 5M system and LSCM, we found that the patients with type 2 DM had more significant morphological and cytological changes and dysfunction in MGs.

Purpose: We performed a retrospective study to evaluate the surgical efficacy and timing of 23-G vitrectomy for acute endophthalmitis following cataract surgery, and to determine when silicone oil tamponade and intraocular lens (IOL) removal are indicated during vitrectomy for endophthalmitis. Methods: We enrolled 21 patients (21 eyes) diagnosed with acute endophthalmitis following cataract surgery who underwent endoscope-assisted 23-G vitrectomy using a wide-angle noncontact lens. Silicone oil tamponade was performed when retinal tear or detachment occurred. The IOL was not removed during primary vitrectomy. Postoperative systemic broad-spectrum antibiotics were used. Results: All infections were controlled by treatment. Best-corrected visual acuity was >0.05 in 14 patients (66.7%) after treatment, which was significantly higher than that before treatment (2/21, 9.5%). Two patients experienced retinal detachment at 10 and 14 days after primary vitrectomy; the IOL was removed during secondary surgery, and silicone oil tamponade was performed. One patient experienced endophthalmitis recurrence 2 months after vitrectomy; secondary surgery was performed to remove the peripheral vitreous body, the pars plana of the ciliary body, and the IOL and capsule. Conclusions: Vitrectomy should be performed when acute endophthalmitis is diagnosed following cataract surgery. Silicone oil tamponade should be performed only when retinal break or detachment occurs. The IOL does not necessarily require removal. © 2015 Wichtig Publishing.

Objectives: To observe sex determining region Y-box 11 (SOX11) gene expression in cutaneous malignant melanoma and its effect on tumour cell proliferation. Methods: Clinicopathological data and tissue samples from patients with cutaneous malignant melanoma, together with tissue samples from healthy volunteers (controls), were retrospectively reviewed. Protein levels of SOX11 and the antigen identified by monoclonal antibody Ki-67 (Ki-67) in skin lesions were analysed using immunohistochemistry. The correlation between protein levels and clinipathological parameters was investigated. Results: Out of 40 patient samples, 25 (62.5%) were positive for SOX11 protein in malignant melanoma tissue. This was significantly higher than in 40 control tissue samples, in which no SOX11 protein was detected. Presence of SOX11 protein was positively related to the proliferation index of cutaneous malignant melanoma tumour cells. Presence of SOX11 protein in cutaneous malignant melanoma was related to tumour type, tumour location, lymph nodemetastasis and 5-year survival rate. Conclusion: Human cutaneous malignant melanoma tissues expressed high levels of SOX11 compared with healthy controls, suggesting that SOX11 may be a new prognostic marker for malignant melanoma. © The Author(s) 2013.

Two new stigmastane-type steroids, stigmasta-5,22E-diene-3β,11α- diol (1) and stigmasta-5,22E-diene-3β,7α,11α-triol (2), together with eight known compounds, were isolated from the resinous exudates of Commiphora mukul. Their structures were established by extensive analysis of their HR-MS, 1D- and 2D-NMR (COSY, HMQC, HMBC and NOESY) spectra. The isolates were evaluated for their antiproliferative activities against four human cancer cell lines. Compound 2 demonstrated inhibitory effects with IC50 values of 5.21, 9.04, 10.94 and 16.56 μM, respectively, against K562, MCF-7, PC3 and DU145 human cancer cell lines. Further study showed that 2 was able to enforce the PC3 cell cycle arrest in the G2/M phase, and induce the apoptosis of PC3 cells by activation of Bax, caspases 3 and 9, and by inhibition of Bcl-2. It was also found that 1 inhibited proliferation of PC3 cells via G0/G1 phase arrest of the cell cycle. © 2012 Elsevier Ltd. All rights reserved.

Estrogen has been closely associated with breast cancer. Several studies reported that Ca2+ signal and Ca2+ channels act in estrogen-modulated non-genomic pathway of breast cancer, however little was revealed on the function of L-type Ca2+ channels. The L-type Ca2+ channel subunit1D, named Cav1.3 was found in breast cancer cells. We aimed to investigate the expression and activity of Cav1.3 in human breast cancer, and reveal the effect of estrogen in regulating the expression of Cav1.3. The qRT-PCR and western blotting were employed to show that Cav1.3 was highly expressed in breast cancer tissues. E2 exposure rapidly upregulated the expression of Cav1.3 in dosage-and time-dependent manner, and promoted Ca2+ influx. The silencing of Gprotein-coupled estrogen receptor30 (GPER1/GPR30) using siRNA transfection inhibited the upregulation of Cav1.3 and Ca2+ influx induced by E2. Moreover, the inhibition of Cav1.3 by siRNA transfection suppressed E2-induced second peak of Ca2+ signal, the expression of p-ERK1/2, and the cell proliferation. Ultrasound-targeted microbubble destruction (UTMD) of Cav1.3 siRNA was used in MCF-7 cells invitro and in the tumor xenografts mice invivo. The application of UTMD significantly suppressed the tumor growth and promoted the survival rate. In conclusion, E2 upregulated the expression of Cav1.3 for Ca2+ influx to promote the expression of p-ERK1/2 for cell proliferation. The study confirmed that the mechanism of E2 inducing the expression of Cav1.3 through a non-genomic pathway, and highlighted that UTMD of Cav1.3 siRNA is a powerful promising technology for breast cancer gene therapy.

Colon cancer remains the second most common cause of cancer-related death, indicating that a proportion of cancer cells are not eradicated by current therapies. Investigation of the molecular mechanisms involved in the development and progression of the disease will aid in the further understanding of the pathogenesis and progression and offer new targets for effective therapies. In the present study, we initially confirmed that ABCA1 was aberrantly expressed in colon cancer tissues and colon cancer cells. Its overexpression inhibited the proliferation of colon cancer HCT116 cells while silencing of ABCA1 promoted the proliferation and inhibited the apoptosis of colon cancer LDL1 cells. Upregulation of specific miRNAs can contribute to the downregulation of tumor-suppressive genes. Thus, we aimed to ascertain whether ABCA1 is downregulated by overexpression of a specific miRNA in colon cancer. We screened microRNAs that may target ABCA1 by miRanda which is a commonly used prediction algorithm. We found that miR-183 targets the 3UTR of ABCA1 mRNA. Subsequent experiments confirmed that miR-183 degraded ABCA1 mRNA in the colon cancer cells. Finally, we demonstrated that miR-183 promoted the proliferation and inhibited the apoptosis of colon cancer cells. Thus, we conclude that miR-183 promotes proliferation and inhibits apoptosis by degrading ABCA1 in colon cancer.

The present study aimed to investigate whether grape seed proanthocyanidin extract (GSPE) has a protective effect on diabetic retinal function. A total of 30 Wistar rats were randomly divided into three equal groups, including the control, diabetic and GSPE-treated diabetic groups. Retinal tissue was harvested and subsequently stained with hematoxylin and eosin. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and methane dicarboxylic aldehyde (MDA) levels were evaluated using respective assay kits; whereas nuclear erythroid 2-related factor 2 (Nrf2) and heme oxygenase (HO)-1 expression levels were assessed by immunohistochemical and western blot analysis. Cell apoptosis in the retina was determined using the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling method. The results showed that the structure of the retina was damaged in diabetic rats, as compared with the control rats. Notably, the structure of the retina improved in the GSPE-treated diabetic group, as compared with the diabetic group. SOD and GSH-Px activities were significantly increased in the retina of rats in the GSPE-treated diabetic group, as compared with the diabetic group (P=0.011 and P=0.001, respectively). Furthermore, a significant reduction in MDA was detected (P=0.013) and the expression levels of Nrf2 and HO-1 in the bladders of rats in the GSPE-treated diabetic group were significantly increased, as compared with the diabetic group (P=0.038 and P=0.043, respectively). Apoptosis of retinal cells was significantly increased in the diabetic group, as compared with the control group (P<0.001); a significant reduction was also detected in the GSPE-treated diabetic group, as compared with the diabetic group (P=0.014). These results demonstrate that GSPE administration may protect the retina against hyperglycemic damage, possibly by ameliorating oxidative stress-mediated injury via the activation of the Nrf2 pathway.
