RESUMO
A meta-analysis based on published literature was undertaken to evaluate the efficacy of anticoagulant drugs for the treatment of venous thromboembolism during pregnancy. PubMed, Cochrane and Embase databases were searched from inception to September 2018 for relevant studies using indexed words, including qualified case-control and cohort studies. The meta-analysis used odds ratios (OR) and 95% confidence intervals (95% CI) to analyse the primary results. Nine studies were included in this meta-analysis, with a total of 834 cases and 3424 controls. There were no significant differences in the incidence of prenatal haemorrhage (OR 1.08, 95% CI 0.84-1.40), venous thromboembolism (OR 1.30, 95% CI 0.72-2.33) or caesarean section (OR 1.16, 95% CI 0.69-1.98) between the case group and the control group. The incidence of pulmonary embolism was significantly higher in the case group than in the control group (OR 3.90, 95% CI 1.23-12.34). However, there were a few limitations that may have influenced the results, so more randomized double-blind controlled studies of high quality are warranted to confirm the efficacy of anticoagulant therapy for venous thromboembolism in pregnancy.

OBJECTIVE: To investigate the medical cost of diabetic patients with foot problems and peripheral artery disease. METHODS: Type 2 diabetic patients with foot problems admitted into the endocrinology departments of 14 teaching hospitals from Jan. 1 to Dec. 31, 2004 were surveyed for their type and phase of foot ulcers, diabetic complications, medical cost and general personal characteristics. RESULTS: The average medical cost of the hospitalization of these patients was RMB yen 14,906 +/- 7072 (about US $ 1640 +/- 873); medication and examination cost was separately 56% and 19% of the total cost. There was obviously higher medical cost for these patients with longer diabetes duration of over 20 years and with the occupation of laborer and retired worker. Patients with kidney disease had significantly higher medical cost than those without (RMB yen 11 690.7 vs yen 9493.0; P = 0.0013), even if the hospital stay was nearly the same (21 days vs 20 days). The medical cost increase with the severity of diabetic foot problems based on the classification of Wagner System or Texas System. Patients with infection, ischemic foot and gangrene foot stayed in the hospitals longer and had much higher medical cost. CONCLUSION: The medical cost is higher for diabetic patients with foot problems and is related with the presence of complicating kidney disease, infection and ischemia as well as the severity of foot ulcers.

OBJECTIVE: To investigate the differences on the diabetic foot problems and its risk factors in south and north of China. METHODS: Patients with foot problems were surveyed from January 1 to December 31, 2004 in 14 teaching hospitals located in different cities in China, including demographic data, present and past history of the foot problems and peripheral artery disease (PAD), the classification of the foot ulcers based on the Wagner' system, control of the hyperglycemia and lipids disorder, medical cost in hospital and the diabetic complications. All the patients were divided into two groups due to their geographical data, south and north. RESULTS: There were 285 and 349 patients for the group south and group north. No significant differences were found for duration of diabetes or foot problems, fasting or post-meal glucose, total cholesterol, triglycerides, HDL-C, and the numbers of patients with smoke, hypertension, nephropathy or neuropathy between the two groups. There were significant differences for the age (70 yrs vs 66 yrs), percentage of the patients with average person income with over RMB 1000 per month (57.7% vs 45.6%), coronary heart disease (42.6% vs 61.0%) and retinopathy (35.7% vs 49.5%), HbA1c (7.90% vs 8.80 %), LDL-C (2.75 mmol/L vs 2.98 mmol/L), WBC (6.70 x 10(9) vs 7.40 x 10(9)/L), HCT (0.37 vs 0.38), creatinine (87 micromol/L vs 76 micromol/L) and uric acid (333 mmol/L vs 271 mmol/L), and amputation rate (2.6% vs 9.7%) between south and north groups. Logistic analysis showed that severity of the foot problems was associated with ABI and WBC in south group, and with ABI, PLT and HCT in north group. CONCLUSION: Diabetic foot problems were more severe, with more risk factors and with more medical cost in north patients.

OBJECTIVE: To investigate the characteristics of diabetic foot with neuropathy and its related factors. METHODS: 530 out- and in-patients in 14 grade A class 3 comprehensive hospitals in China with foot problems were surveyed. 337 of the 500 patients (63.58%) suffered from neuropathy, 172 (32.45%) with diabetic foot with simple neuropathy and 165 (31.13%) with simple neuropathy combined with peripheral artery disease (PAD). 193 of the 500 patients (36.42%) suffered from peripheral artery disease (PAD). 77.7% of ulcer were caused by physical factors. Questionnaire survey was conducted to collect the demographic data, present and past history, history of the hyperglycemia and lipid disorders, classification and phases of the foot ulcers based on Wagner' system and Texas system, characteristics of neuropathy and other diabetic complications, and relative risk factors. Detailed physical examination was performed, including 10 g nylon filament sensation examination. RESULTS: The duration of diabetic foot of the patients with simple neuropathy was 3 (1, 60) months, significantly shorter than that of the diabetic foot patients with PAD [5 (1, 96) months, P < 0.001]. The Wagner degree of ulcer was related to the duration of diabetes, economic income, foot deformity, nerve reflection, diapason vibration sensation of foot, sensation point of 10 g nylon filament, ankle/brachial index (ABI), foot artery pulse, fasting blood sugar (FBS) and glycated hemoglobin (HbA1c). Stepwise regression analysis revealed that ABI of left posterior tibial artery, vibration detection threshold and economic income were the most significant influencing factors of the degree of ulcer. CONCLUSION: Neuropathy ulcer is common in diabetic foot patients. The prognosis of healing in diabetic foot with neuropathy is prior to that of diabetic foot with PAD. The neuropathy and PAD of foot influence each other and aggravate the condition of diabetic foot. The examinations of diapason vibration sensation of foot, sensation point of 10 g nylon filament, and Achilles tendon reflex are simple and practical, and are worth recommending.

OBJECTIVE: To evaluate the value of 640-slice 3D CT angiography (3D-CTA) plus 3D printing for improving the outcomes of surgeries for intracranial aneurysms. METHODS: Sixty patients with intracranial aneurysm were randomly divided into trial group (n=30) and control group (n=30). The control group received routine surgery, and the simulation models of the intracranial aneurysm in trial group was printed using a 3D printer using the imaging data from 3D-CTA. Using the simulation model, the surgery was designed and planned before operation (including surgical approaches and placement of clips) and simulation surgery was also conducted. The coincidence rates between preoperative and intraoperative findings of the intracranial aneurysms on 3D-CTA were compared. CT scan was performed at 1 and 3 days after the operation to detect potential cerebral infarction or bleeding associated with the operation; CTA was performed both at the same time and at 3-6 months after the operation to detect stenosis, occlusion and aneurysm clipping. The patients were followed up for 3-6 months to assess the outcomes using Glasgow Outcome Scale (GOS). RESULTS: The preoperative 3D-CTA findings were basically consistent with the intraoperative findings in all the 60 patients. Nine patients in the control group and 2 patients in the trial group had short-term adverse operation events; 11 patients in control group and 4 patients in trial group had long-term adverse events; 18 patients in control group and 25 patients in trial group had good neurologic function. The incidences of short-term and long-term adverse events associated with the operation was significantly lower in the trial group than in the control group (χ2=5.364, P=0.021; χ2=4.841, P=0.028), and the outcomes were significantly better in the trial group than in the control group (χ2=4.633, P=0.031). CONCLUSION: The simulation model of intracranial aneurysm is helpful to improve the quality of surgery and patients outcomes.
RESUMO
The present study aimed to investigate the role of JWA gene in the proliferation, apoptosis, invasion and migration of PANC-1 pancreatic cancer cells and the effect on the MAPK signaling pathway. Human PANC-1 pancreatic cancer cells were cultured in vitro, and small interfering RNA (siRNA) was designed for the JWA gene. The siRNA was transfected into PANC-1 cells. Subsequently, the cell proliferation was measured by MTT assay; cell apoptosis was detected by analyzing BAX and Bcl-2 protein expression; cell migration and invasion were measured using Transwell® chambers; and the protein expression of JWA and ERK1/2, JNK and p38 and their phosphorylated forms were measured by western blotting. By utilizing the MTT assay, the results showed that when JWA protein expression was inhibited, the proliferation of PANC-1 cells was enhanced. In addition, the expression of apoptosis-associated protein (AAP) BAX was substantially decreased, while the expression of the apoptosis inhibitor gene, Bcl-2, was significantly enhanced. Using Transwell chambers, it was found that the number of penetrating PANC-1 cells was significantly increased after transfection with JWA siRNA, suggesting that the migration and invasion of the cells was substantially increased. By studying the association between JWA and the MAPK pathway in PANC-1 cells, it was found that the expression of p-ERK1/2 of the MAPK pathway was significantly downregulated following JWA siRNA transfection. However, the expression levels of ERK1/2, JNK, p38, p-JNK and p-p38 showed no significant differences. In conclusion, it was shown that JWA affects the proliferation, apoptosis, invasion and migration of PANC-1 pancreatic cancer cells which could be attributed to effects on the expression of ERK1/2 in the MAPK pathway.
