Objective To explore the value of automatic photography in the observation of results of Schistosoma japoni?cum miracidium hatching experiments. Methods Some fresh S. japonicum eggs were added into cow feces,and the samples of feces were divided into a low infested experimental group and a high infested group(40 samples each group). In addition,there was a negative control group with 40 samples of cow feces without S. japonicum eggs. The conventional nylon bag S. japonicum miracidium hatching experiments were performed. The process was observed with the method of flashlight and magnifying glass combined with automatic video(automatic photography method),and,at the same time,with the naked eye observation meth?od. The results were compared. Results In the low infested group,the miracidium positive detection rates were 57.5% and 85.0%by the naked eye observation method and automatic photography method,respectively(χ2=11.723,P<0.05). In the high infested group,the positive detection rates were 97.5%and 100%by the naked eye observation method and automatic pho?tography method,respectively(χ2= 1.253,P > 0.05). In the two infested groups,the average positive detection rates were 77.5% and 92.5% by the naked eye observation method and automatic photography method,respectively(χ2 = 6.894,P <0.05). Conclusion The automatic photography can effectively improve the positive detection rate in the S. japonicum miracidi?um hatching experiments.

Objective To investigate the effective administration model for gestational diabetes mellitus (GDM) in the community. Methods In a prospective study, the 75 g oral glucose tolerance test (OGTT) was performed in 4 713 resident pregnant women over 20 years old who received antenatal care in a general hospital or a special hospital from Sep. 2011 to Aug. 2012. Five hundred and thirty-three pregnant women were diagnosed as GDM, 198 patients who labored in a general hospital were enrolled in thegroup A , and the rest who labored in a special hospital were enrolled in the group B. 198 cases with non-GDM were enrolled in the group C. Results The incidence of GDM during this study period was 11.3%. The maternal age , gestationl weeks and OGTT results of patients in the three groups were significantly different (P < 0.05). With the increase of maternal age of pregnant women, the blood glucose increased while the gestationl weeks descreased. No significant differencees were shown in prevalence of polyhydramnios, hypertensive disorder complicating pregnancy, premature labor, macrosomia , fetal growth restriction and neonatal asphyxia among the three groups (P > 0.05). However, significant differences were found in the incidence of postpartum hemorrhage and cesarean section. The incidence of postpartum hemorrhage increased significantly in the patients of group B (χ2= 7.156, v = 2, P = 0.028). The incidence of cesarean section increased significantly in the patients of group A (χ2= 63.592, v = 2, P = 0.000). Conclusion Establishing an effective administration model for gestational diabetes mellitus in the community could control the incidence of GDM associated complications.

Results The scores of all the assessments improved in both groups after treatment (P<0.001),and improved more in the electromyography-triggered stimulation group than in the neuromuscular electric stimulation group (P<0.05).Conclusion Compared with neuromuscular electrical stimulation, electromyography-triggered stimulation may further improve the hand function post stroke

Objective:To explore the association of tumor associated macrophages (TAM) with tumor invasiveness, metastasis and prognosis in cardia carcinoma tissues.Methods:The cancer tissues and pericarcinomatous tissues of 100 patients with cardia carcinoma who underwent D2 radical operation in the First Hospital of Putian City from January 2014 to January 2015 were collected. M2-type TAM was marked with CD163. The tissue microarray was made and the expression of CD163 in microarray tissues was detected by using immunohistochemistry. The median number of CD163 positive cells in all cancer tissues was taken as the cut-off value. The patients with the mean number of CD163 positive cells ≥ the cut-off value were those with high TAM infiltration, and vice versa. The association of TAM infiltration with clinicopathological features and prognosis was analyzed, and Cox proportional hazards model was used for multivariate analysis of survival.Results:The positive cell median number of CD163 in cardia carcinoma tissues was higher than that in adjacent tissues [the median number ( P25, P75): 32/high power field (HP) (16/HP, 46/HP) vs. 6/HP (4/HP, 11/HP)], and the difference was statistically significant ( Z = -35.044, P < 0.01). There were 48 cases in low invasive group (< 32/HP) and 52 cases in high invasive group (≥32/HP). The proportion of patients with high TAM infiltration in serosa and extraserosa was higher than that in mucosa and muscle [60.9% (39/64) vs. 36.1% (13/36)], and the proportion of patients with high TAM infiltration for patients with lymph node metastasis was higher than that for patients without lymph node metastasis [61.8% (42/68) vs. 31.3% (10/32)], and the proportion of patients with high TAM infiltration for those with TNM stage Ⅲ-Ⅳ was higher than that for those with TNM stage Ⅰ-Ⅱ [64.4% (38/59) vs. 34.1% (14/41)], and the differences were statistically significant (all P < 0.05). The median overall survival time of high TAM group was shorter than that of low TAM group [24.00 months (95% CI 17.25-43.50 months) vs. 62.00 months (95% CI 34.00-68.00)], and the difference in overall survival was statistically significant (χ 2 = 18.137, P < 0.01). Lymph node metastasis ( HR = 0.301, 95% CI 0.105-0.862, P = 0.025), TNM staging ( HR = 8.404, 95% CI 2.810-25.133, P < 0.01) and TAM infiltration level in cancer tissues ( HR = 4.277, 95% CI 2.372-7.712, P < 0.01) were independent influencing factors for overall survival of patients. Conclusions:TAM plays an important role in the invasion and metastasis of cardia carcinoma and can be used as an independent predictor of biological behavior and prognosis in cardia carcinoma.

Deproteinized calf blood injection is composed of small protein-free molecules extracted from fresh calf blood. The pre-vious studies showed that it can improve metabolic balance by increasing glucose and oxygen uptake to enhance energy metabolism. In recent years, due to the expanding clinical applications of deproteinized calf blood injection, new observation results and ideas contin-ued to emerge. However, the reports of adverse reactions and excessive applications were also gradually increased. In order to provide reference for the promotion of reasonable clinical application, the paper reviewed the latest development in the studies on the clinical application of deproteinized calf blood injection.

To evaluate the different anesthesia in elderly patients with gastric cancer surgery influence blood con-centrations of melatonin and its correlation with postoperative agitation. The agitation scroes were evaluated and re-corded,and the blood samples were taken twice:before induction as well as just at the end of surgery,then making correlation analysis. The agitation scroes were significantly lower in group ET than in group T(P<0.01);the level of postoperative blood concentrations of melatonin was higher in group ET than that in group T(P<0.01);the agi-tation scroes and the level of postoperative blood concentrations of melatonin were negatively correlated ( r =-0.429,P<0.05).

Objective To evaluate the feasibility and safety of laparoscopic right hemihepatectomy under selective hemihepatic inflow occlusion.Methods In performing this procedure,first dissect the right hepatic portal,and under selective hemihepatic inflow occlusion,laparoscopie Peng's multifunctional operative dissector (LPMOD) was used to transect the hepatic parenchyma by stepwise curettage and aspiration.Results Procedures were successful in all six patients of benign liver diseases,though a small subcostal auxiliary incision was needed in one case to control the middle hepatic vein branch hemorrhage.Operation time was 300-540 min[mean,( 399 ± 75 ) min].The time of hepatic portal dissect was 30-75 min[mean,(51 ± 16) min].The time of liver parenchyma transection was 60-160 min[mean,( 116 ± 32) min].Intraoperative blood loss was 600-3000 ml[mean,( 1486 ± 809 ) ml].The level of ALT increased to (302-557) U/L[mean,(386 ± 85 ) U/L]after the operation,and back to normal level in 5-11 d[mean,( 7.1 ± 2.0) d].The postoperative hospital stay was 10-18 d[mean,( 12.4 ± 2.6 ) d].No severe complication occurred after the operation.Conclusions Laparoscopic right hemihepatectomy under selective hemihepatic inflow occlusion is safe and feasible.

Objective To explore the clinicopathological features of IgA nephrolpathy associated with malignant hypertension (IgAN-MHT) and to analyze their correlation with renal vascular lesions. Methods Twenty-nine patients of IgAN-MHT were screened from 2000 biopsy-proven eases with primary IgA nephropathy (IgAN) in our department from April 1997 to May 2007. Data of clinicopathology and follow-up of these 29 patients were collected. Semi- quantitative analysis was performed to evaluate the pathological changes. Inner lumen, outer lumen, intimal thickness, tunica media-to-internal lumen ratio of 436 arterioles, 124 interlobular arteries and 5 arcuate arteries were measured. The primary endpeint was the composite of a doubling of serum creatinine level and ESRD. Correlations of renal vascular lesions with clinical manifestation, pathological change and prognosis were examined by Spearman and Cox methods. Results 1.5% of all the IgAN patients presented malignant hypertension. The common clinical features were renal failure (100%), hyperurieacidemia (62.7%) and hypertriglyceridemia (51.7%). The average amount of urine protein excretion was 2.8 g/d. The common pathological changes were moderate mesangial proliferation, severe global sclerosis, severe interstitial inflammation and severe interstitial- tubular fibrosis. The small arteries (arcuate arteries and interlobular arteries) and arterioles (afferent arterioles) were both involved in IgAN-MHT. The characteristic lesions of intrarenal arteries included vascular occlusion, media thickening, proliferative endarteritis (onionskin lesion, musculomucoid intimal hyperplasia), hyaline arteriosclerosis, but mainly vascular occlusion (86.2%). The arteriole lesion was negatively correlated with age and total protein level; vascular occlusion was positively correlated with uric acid level. The average foUow-up period was 21.1 months. Forteen patients reached the endpoint. The arteriole lesion was the main independent risk factor for the progression of IgAN-MHT (RR=10.21, 95%CI=1.16～89.67). Conclusions The main clinical feature of IgAN-MHT is renal failure. The main histological feature of intrarenal vascular lesions is occludes arterioles. Arteriole lesion is the main independent risk factor for the progression of IgAN-MHT.
