In recent years, the incidence of early colon cancer (ECC) in China showed a rising trend. Accurate definition of ECC is of great significance for disease assessment, treatment decision-making and prognosis judgment. Although endoscopic resection has become an option in the treatment of ECC, surgical intervention is still needed for tumor residue and high risk pT1 tumors in order to prevent recurrence and metastasis. There is no consensus on indication, timing, radical resection range and tumor location of ECC surgery. The innovation of laparoscopic surgical techniques strongly promoted the progress of ECC minimally invasive surgery. Postoperative follow-up should be systematic, standardized and individualized, based on the stratification of ECC recurrence risk factors.

The purification of parasite-infected erythrocytes from whole blood containing leucocytes is crucial for many downstream genetic and molecular assays in parasitology. Current methodologies to achieve this are often costly and time consuming. Here, we demonstrate the successful application of a cheap and simple Non-Woven Fabric (NWF) filter for the purification of parasitized red blood cells from whole blood. NWF filtration was applied to the malaria-parasitized blood of three strains of mice, and one strain of rat, and to Babesia gibsoni parasitized dog blood. Before and after filtration, the white blood cell (WBC) removal rates and red blood cell (RBC) recovery rates were measured. After NWF filter treatment of rodent malaria-infected blood, the WBC removal rates and RBC recovery rates were, for Kunming mice: 99.51%±0.30% and 86.12%±8.37%; for BALB/C mice: 99.61%±0.15% and 80.74%±7.11%; for C57 mice: 99.71%±0.12% and 84.87%±3.83%; for Sprague-Dawley rats: 99.93%±0.03% and 83.30%±2.96%. Microscopy showed WBCs were efficiently removed from infected dog blood samples, and there was no obvious morphological change of B. gibsoni parasites. NWF filters efficiently remove leukocytes from malaria parasite-infected mouse and rat blood, and are also suitable for filtration of B. gibsoni-infected dog blood.

The cochlea of children with congenital sensorineural hearing loss with normal inner ear structure was measured and analyzed by high-resolution temporal bone CT(HRCT) imaging technique,its application value before cochlear implantation was evaluated and the appropriate electrode was selected.We collected temporal bone HRCT images of 120 patients with congenital sensorineural hearing loss,according to gender divided into two groups,including 60 males and 60 females.We used the PACS software to measure the distance A(the largest distance from the round window to the lateral wall) and the distance H(height of the cochlea) and calculate the cochlear duct length. Reproducibility of these data were evaluated and the results between the different groups were compared.Measurement of parameter values between the intraobserver and interobserver showed great reproducibility. In the male children group,the measured values are shown as distance A［(8.55±0.31)mm］,distance H［(4.57±0.28)mm］and the cochlear duct length(CDL)［(27.59±1.23)mm］; and in the female children group, the measured values are shown as distance A［(8.45±0.32)mm］,distance H［(4.42±0.34)mm］and the cochlear duct length(CDL)［(27.20±1.17)mm.The A,H,and CDL of the male cochlea were greater than those of the female, the difference was statistically significant(<0.05).Measuring the distance A and distance H of the cochlea and calculating the cochlear duct length CDL can be used to select a suitable length of electrode or to customize a personalized electrode. This is a simple and effective assessment method before cochlear implantation..

Objective: To understand the prevalence of major human parasitic diseases and related factors in Henan province. Methods: This stratified sampling survey was carried out according to the requirement of national survey protocol of major human parasitic diseases, 2014-2015. The prevalence of soil-transmitted helminths infection, taeniasis and intestinal protozoiasis were surveyed in 104 sites selected from 35 counties (districts) and the prevalence of clonorchiasis was surveyed in 62 sites selected from 37 townships. In each survey spot, 250 persons were surveyed. A total of 26 866 persons and 15 893 persons were surveyed. Modified Kato-Katz thick smear was used to detect the eggs of intestinal helminthes. Tube fecal culture was used to identify the species of hookworm. The Enterobius eggs were detected in children aged 3 to 6 years by using adhesive tape. The cyst and trophozoite of intestinal protozoa were examined with physiological saline direct smear method and iodine stain method. Results: The overall infestation rate of intestinal parasites was2.02% in Henan, and the worm infection rate was higher than protozoa infection rate. Fourteen kinds of intestinal parasites were found, including nematode (5 species), trematode (2 species), and protozoan (7 species). The infection rate of Enterobius vermicularis was highest, and Qinba Mountain ecological area had the highest infestation rate of intestinal parasites in 4 ecological areas of Henan. There was no significant difference in intestinal parasite infection rate between males and females (χ(2)=3.630, P=0.057), and the differences in intestinal parasite infection rate among different age groups had significance (χ(2)=124.783, P=0.000 1). The infection rate reached the peak in age group ≤9 years and the major parasite was Enterobius vermicularis. Furthermore the overall human infection rate of parasite showed a downward trend with the increase of educational level of the people (χ(2)=70.969, P=0.000 1), the differences had significance (χ(2)=120.118, P=0.000 1). For different populations, the infection rate of intestinal parasites was highest among preschool children. The infection of intestinal helminth was mainly mild, only 2 severe cases were detected. The infection rate of Clonorchis sinensis in urban residents was only 0.006%. Logistic regression analysis showed that being preschool children (χ(2)=15.765, P=0.000 1) and drinking well water (χ(2)=45.589, P=0.000 1) were the risk factors for intestinal parasite infection, and annual income per capita of farmers was the protective factor against intestinal parasite infection. The infection rates of protozoa and intestinal parasites decreased sharply compared with the results of previous two surveys, and the rate of intestinal helminth infection also dropped sharply compared with the second survey. The numbers of protozoa, helminth and intestinal parasites detected in this survey were all less than the numbers found in the previous two surveys. Conclusions: Compared the results of three surveys in Henan, the infection rate of protozoa and intestinal parasites showed a downward trend. The prevention and treatment of Enterobius vermicularis infection in children should be the key point of parasitic disease control in the future.

Objective: To evaluate the effect of health literacy and exercise-focused interventions on glycemic control in patients with type 2 diabetes (T2DM) in China. Methods: In this cluster randomized controlled trial, a total of 799 T2DM patients with most recent hemoglobin A1c (HbA1c) ≥ 7.5% (or fasting plasma glucose level ≥10 mmol/L) were recruited from 8 communities in Minhang and Changning districts of Shanghai, and randomized into a health literacy intervention group, an exercise intervention group, a comprehensive intervention group and a control group. After baseline survey and examination, a one-year intervention and 3 times (at 3(rd), 6(th), and 12(th) month) follow-up surveys were conducted. Results: The follow-up rates for all the subjects were 99.4%, 98.4% and 95.2%, respectively, at 3(rd), 6(th) and 12(th) month. Patients in intervention groups were more likely to achieve a goal HbA1c level (HbA1c <7.0%) than those in control group, with the highest glycemic control rate (25.3%) observed in comprehensive intervention group at 3(rd) month and then in exercise intervention group (25.3% and 34.6%) respectively, at 6(th) month and 12(th) month. The average levels of HbA1c in three intervention groups were lower at each follow-up time point than those at baseline survey. However, the decreases in HbA1c were obvious only at 6(th) month (P<0.001), with ls-mean (95%CI) of -0.48% (-0.71%, -0.25%), -0.33% (-0.55%, -0.11%) and -0.70% (-0.92%, -0.48%), respectively, in comprehensive, health literacy and exercise intervention groups, but it increased slightly by 0.03% (-0.19%, 0.25%) in control group. Compared with control group, the interventions were significantly associated with the decrease of HbA1c level, with the most improvement observed in comprehensive group (β=-0.47, 95% CI: -0.73, -0.20) at 3(rd) month, and in exercise intervention group at 6(th) month (β=-0.73, 95%CI: -0.98, -0.47) and at 12(th) month (β=-0.75, 95%CI: -1.05, -0.45) of follow-up. Stratified analyses showed that patients with lower health literacy level could benefit from any intervention, while those with higher numeracy skill benefited more from exercise intervention. Conclusion: Both health literacy and exercise-focused interventions may decrease HbA1c level in patients with T2DM, which would be helpful in reducing the risks of complications and deaths in diabetes patients.

Objective: To explore the survival factors and construct a prognostic index (PI) for oral squamous cell carcinoma (OSCC). Methods: From January 2004 to June 2016, a total of 634 patients with pathologically confirmed OSCC were recruited in a hospital of Fujian. The clinical and follow-up data of all the patients with pathologically confirmed OSCC were collected to identify the factors influencing the prognosis of OSCC. All the patients were randomly divided into two groups: modeling group (modeling dataset, n=318) and validation group (validation dataset, n=316). Randomization was carried out by using computer-generated random numbers. In the modeling dataset, survival rates were calculated using Kaplan-Meier method and compared using the log-rank test. Cox regression model was used to estimate the hazard ratio (HRs) and 95% confidence intervals (CIs) of prognosis factors. An PI for OSCC patients prognostic prediction model was developed based on β value of each significant variable obtained from the multivariate Cox regression model. Using the tertile analysis, patients were divided into high-risk group, moderate-risk group, and low-risk group according to the PI, the Akaike information criterion (AIC) and Harrell's c-statistic (C index) were used to evaluated the model's predictability. Results: Results from the multivariate Cox regression model indicated that aged ≥55 years (HR=2.22, 95%CI: 1.45-3.39), poor oral hygiene (HR=2.12, 95%CI: 1.27-3.54), first diagnosis of lymph node metastasis (HR=5.78, 95%CI: 3.60-9.27), TNM stage Ⅲ-Ⅳ (stage Ⅰ as reference) (HR=2.43, 95%CI: 1.10-5.37) and poor differentiation (well differentiation as reference) (HR=2.53, 95%CI: 1.60-4.01) were the risk factors influencing the prognosis of OSCC. The PI model had a high predictability in modeling group and validation group (AIC and C index were 1 205.80, 0.700 2 and 1 150.47, 0.737 3). Conclusion: Age, poor oral hygiene, first diagnosis of lymph node metastasis, TNM stage and histological grade were factors associated with the prognosis of OSCC, and the PI model has a certain significance in the clinical treatment of OSCC.

Objective: To explore the association between maternal respiratory infection in early pregnancy and gestational age of single live birth. Methods: A face to face questionnaire survey was conducted among child bearing aged women in 30 counties (district) of Shaanxi province selected through stratified multistage sampling. Propensity score (PS) matched (1∶1) analysis was used to match participants with respiratory infections to those without respiratory infections. A multilevel linear model was used to investigate the association between respiratory infections and gestational age. Through the control of the confounders step by step, three models were established in this study: model 1 for the variable of respiratory infections before PS matching, model 2 was adjusted for variables in model 1 plus some other individual differences of mother and baby, and model 3 for the variable of respiratory infections after PS matching. Results: Of 28 848 child bearing aged women surveyed, 3 676 (12.74%) had respiratory infections in early pregnancy. After PS matching, 2 762 pairs were matched. Analysis with model 1 indicated that a decrease of 0.111 week (P<0.001) in gestational age was associated with a respiratory infection during the first trimester. Analysis with model 2 and model 3 indicated that a decrease of 0.058 week (P=0.025) and a decrease of 0.076 week (P=0.036) were associated with respiratory infection during the first trimester, respectively. Conclusion: The respiratory infection during the first trimester was associated with the decrease of the gestational age of newborn.
