OBJECTIVEthe aim of this study was to determine the clinicopathological characteristics of colorectal cancer (CRC) patients complicated with type 2 diabetes mellitus (T2DM ).
METHODSA total of 3, 202 patients with CRC confirmed pathologically in Tianjin Union Medicine Center from January 2005 to December 2009 were included in this study. We analyzed the differences in clinicopathological features between T2DM patients and non-diabetic patients according to age of diagnosis, gender, tumor site, stage, gross type, histological type, and differentiation.
RESULTSFrom 2005 to 2009, the number of CRC patients increased yearly. The high incidence age of all CRC patients was 51 to 80 years old. The male to female ratio was 1.18:1, showing that the number of female patients with CRC was increased significantly compared with males. The CRC distribution of T2DM patients and non-diabetic patients showed a predominance of rectal cancer (64.4%, 68.7%), followed by sigmoid colon cancer (12.5%, 13.0%), and moderately differentiated ulcer-type adenocarcinoma. Compared with non-diabetic patients, T2DM patients were older (66.2 years versus 62.7 years, P < 0.001) and had more multiple CRCs (3.5% versus 1.6%, P < 0.001). Moreover, the proportion of lymph node or organ metastasis in T2DM patients was higher than that in non-diabetic patients (52.6% versus 45.6%, P < 0.05). No significant differences were observed between both groups in terms of gender, gross type, histological type, and differentiation(P > 0.05 for all).
CONCLUSIONSCRC incidence shows an increasing trend with age. CRC patients with T2DM have an older age of onset, higher proportion of lymph node and distant organ metastasis than in non-diabetic patients.

ObjectiveTo investigate the protective effect of modified Huangqi Guizhi Wuwutang (MHGW) on endoplasmic reticulum stress in the sciatic nerve of diabetes rats based on the pathways of inositol-requiring enzyme 1α (IRE1α) and CCAAT/enhancer-binding protein homologous protein (CHOP). MethodSixty rats were fed on a high-sugar and high-fat diet for six weeks, followed by intraperitoneal injection of streptozotocin at a dose of 35 mg·kg-1. Random blood glucose levels were measured three days later and rats with a sustained blood glucose level ≥ 16.7 mmol·L-1 were included in study (n=48). The rats were randomly divided into a model group, an α-lipoic acid group (0.026 8 g·kg-1·d-1), a high-dose MHGW group (2.5 g·kg-1·d-1), and a low-dose MHGW group (1.25 g·kg-1·d-1). Another 10 rats were assigned to the normal group. The intervention lasted for 16 weeks. After 16 weeks, the sciatic nerve structure of the rats in each group was observed under light microscopy using Luxol fast blue (LFB) staining. Transmission electron microscopy was used to observe the ultrastructure of the sciatic nerve. Chemiluminescence method was employed to measure the serum reactive oxygen species (ROS) levels. Western blot and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) were used to evaluate the expression of p-IRE1α protein, IRE1α mRNA, CHOP protein, and CHOP mRNA in the sciatic nerve of the rats. ResultCompared with the normal group, the model group showed elevated serum ROS levels (P<0.01). In contrast, the serum ROS levels were significantly reduced in the treatment groups compared with those in the model group (P<0.01). The sciatic nerve of the model group showed pathological changes compared with that in the normal group, while the treatment groups exhibited improvement in sciatic nerve pathology compared with the model group. The protein expression of p-IRE1α and CHOP in the sciatic nerve significantly increased in the model group as compared with that in the normal group (P<0.01). However, the treatment groups showed a significant decrease in the protein expression of p-IRE1α and CHOP in the sciatic nerve compared with the model group (P<0.05, P<0.01). Furthermore, compared with the normal group, the model group showed upregulated mRNA expression of IRE1α and CHOP in the sciatic nerve (P<0.01), while the treatment groups exhibited a significant decrease in the mRNA expression of IRE1α and CHOP compared with the model group (P<0.01). ConclusionMHGW can alleviate endoplasmic reticulum stress-induced cell apoptosis and improve the structure and function of the sciatic nerve in diabetes rats by inhibiting the expression of IRE1α/CHOP pathway-related proteins and mRNA, thereby preventing and treating peripheral neuropathy in diabetes.

Background:
In China, secondary cytoreductive surgery (SCR) has been widely used in ovarian cancer (OC) over the past two decades. Although Gynecologic Oncology Group-0213 trial did not show its overall survival benefit in first relapsed patients, the questions on patient selection and effect of subsequent targeting therapy are still open. The preliminary data from our pre-SOC1 phase II study showed that selected patients with second relapse who never received SCR at recurrence may still benefit from surgery. Moreover, poly(ADP-ribose) polymerase inhibitors (PARPi) maintenance now has been a standard care for platinum sensitive relapsed OC. To our knowledge, no published or ongoing trial is trying to answer the question if patient can benefit from a potentially complete resection combined with PARPi maintenance in OC patients with secondary recurrence.
Methods
SOC-3 is a multi-center, open, randomized, controlled, phase II trial of SCR followed by chemotherapy and niraparib maintenance vs chemotherapy and niraparib maintenance in patients with platinum-sensitive second relapsed OC who never received SCR at recurrence. To guarantee surgical quality, if the sites had no experience of participating in any OC-related surgical trials, the number of recurrent lesions evaluated by central-reviewed positron emission tomography–computed tomography image shouldn't be more than 3. Eligible patients are randomly assigned in a 1:1 ratio to receive either SCR followed by 6 cyclesof platinum-based chemotherapy and niraparib maintenance or 6 cycles of platinum-based chemotherapy and niraparib maintenance alone. Patients who undergo at least 4 cycles of chemotherapy and must be, in the opinion of the investigator, without disease progression, will be assigned niraparib maintenance. Major inclusion criteria are secondary relapsed OC with a platinum-free interval of no less than 6 months and a possibly complete resection. Major exclusion criteria are borderline tumors and non-epithelial ovarian malignancies, received debulking surgery at recurrence and impossible to complete resection. The sample size is 96 patients. Primary endpoint is 12-month non-progression rate.

ObjectiveTo investigate the effect of modified Huangqi Guizhi Wuwutang (MHGW) on the protein and mRNA expression of B-cell lymphoma-2-associated X protein (Bax) and cysteinyl aspartate specific proteinase-12 (Caspase-12) related to the apoptosis of sciatic nerve cells in diabetes rats to explore the mechanism of MHGW in the treatment of peripheral neuropathy in diabetes. MethodAnimal experiments were conducted. A diabetes model was induced in sixty male sprague-dawley (SD) rats by feeding on a high-sugar and high-fat diet combined with streptozotocin (STZ) intraperitoneal injection. Rats with random blood glucose levels ≥ 16.7 mmol·L-1 for three consecutive days were considered to have successfully developed diabetes. Forty-eight rats that successfully developed diabetes were randomly divided into a model group, an α-lipoic acid group (0.026 8 g·kg-1·d-1), a high-dose MHGW group (2.5 g·kg-1·d-1), and a low-dose MHGW group (1.25 g·kg-1·d-1), with 12 rats in each group. Another 10 rats were assigned to the normal group. Body weight and random blood glucose levels of the rats were monitored. At the end of a 16-week intervention period, the sciatic nerve conduction velocity of the rats was measured using the Key point electromyography collection system. The protein and mRNA expression of Bax and Caspase-12 in the sciatic nerve cells was detected by Western blot analysis and real-time quantitative polymerase chain reaction (Real-time PCR), respectively. ResultCompared with the normal group, the model group showed a significant decrease in body weight (P<0.01) and a significant increase in random blood glucose levels (P<0.01). After a 16-week intervention, compared with the model group, the high-dose MHGW group exhibited a significant increase in body weight (P<0.05), while there were no statistically significant differences in body weight changes among the other treatment groups. Random blood glucose levels significantly decreased in all treatment groups (P<0.01). After 16 weeks of intervention, compared with the normal group, the model group had significantly reduced motor and sensory nerve conduction velocities (P<0.01). Compared with the model group, all treatment groups showed significant increases in motor and sensory nerve conduction velocities (P<0.05, P<0.01). The expression of Bax and Caspase-12 proteins in the sciatic nerve cells was significantly elevated in the model group compared with that in the normal group (P<0.01). In contrast, all treatment groups showed significant reductions in the expression of Bax and Caspase-12 proteins in the sciatic nerve cells as compared with that in the model group (P<0.01). The expression of Bax and Caspase-12 mRNA in the sciatic nerve cells significantly increased in the model group compared with that in the normal group (P<0.01). Compared with the model group, the α-lipoic acid group and the high-dose MHGW group showed significant reductions in the expression of Bax mRNA in the sciatic nerve cells (P<0.05, P<0.01), while the low-dose MHGW group showed a decreasing trend in the expression of Bax mRNA. The expression of Caspase-12 mRNA in the sciatic nerve cells significantly decreased in all treatment groups (P<0.01). ConclusionMHGW may improve and repair sciatic nerve damage in diabetes rats by inhibiting sciatic nerve cell apoptosis.
