Objective To investigate the relationship between gene polymorphism of factor VII R353Q (FVII R353Q) and cerebral palsy for Han Chinese children. Methods Polymerase chain reaction-restricted fragment length polymorphism were used to determine genotype and allele of R353Q gene in 160 children with cerebral palsy and 137 normal children. Results The genotype of FVII R353Q is close to Hardy-Weinberg equilibrium in both CP group and control group (P>0.05). There was not significant difference in the distribution of the allelic frequency and genotype of FVII R353Q between the both groups (P=0.436, P=0.182, respectively). Conclusion The gene polymorphism of FVII R353Q is not significantly related with cerebral palsy for Han Chinese children.

Objective To explore the relationship between postoperative cancer-related fatigue and nutritional risk in patients with colorectal cancer. Method Using convenience sampling method, 159 postoperative colorectal cancer patients were interviewed with cancer-related fatigue scale and PG-SGA 7 days after operation. Results The average score of CRF was (21.28 ± 6.06). The score by PG-SGA was (15.18 ± 5.55). About 94.34%patients were in need of nutritional intervention. The postoperative cancer-related fatigue was positively related to PG-SGA scores(all P<0.05). Conclusions The postoperative colorectal cancer patients are at a high risk of malnutrition, with nutrition risk positively related with somatic cancer-related fatigue. The clinical nursing staff should pay attention to the nutritional status of patients and correct their malnutrition so as to reduce the symptoms of cancer-related fatigue.

Objective:To investigate the effect of single-port laparoscopy and conventional laparoscopic surgery in ovarian cystectomy.Methods:The clinical data of 139 patients with laparoscopic surgery for ovarian cyst admitted to the same department of gynecology from December 2016 to December 2019 in Suzhou Hospital Affiliated of Anhui Medical University were retrospectively analyzed, and they were divided into single-port laparoscopic surgery group (62 cases) and conventional laparoscopic surgery group (77 cases) according to different surgical methods. The clinical indictors, the levels of estrogen, T lymphocyte subgroups, the complications rate and incision satisfaction rate between two groups were compared.Results:The operation in both groups was smooth and there was no conversion to open surgery. Compared with the conventional laparoscopic surgery group, the surgery time, intraoperative blood loss in single-port laparoscopic surgery group were higher, the hospital stays in single-port laparoscopic surgery group was shorter, but there were no significant differences ( P>0.05). The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E 2) in two groups before operation had no significant differences ( P>0.05). At 30 d after operation, the levels of FSH, LH and E 2 in single-port laparoscopic surgery group were higher than those in conventional laparoscopic surgery group, but the differences were no statistically significant ( P>0.05). Before operation, the levels of CD 4+, CD 8+ and CD 4+/CD 8+ in two groups has no significant differences ( P>0.05). At 3 d after operation, the levels of CD 4+, CD 8+ and CD 4+/CD 8+ in single-port laparoscopic surgery group were higher than those in conventional laparoscopic surgery group: 0.51 ± 0.03 vs. 0.47 ± 0.02, 0.41 ± 0.23 vs. 0.39 ± 0.05, 1.36 ± 0.02 vs. 1.24 ± 0.02, and the differences were statistically significant ( P<0.05). The rate of complication in two groups had no significant difference ( P>0.05). At 3 d after operation, the scores of visual analogue scale (VAS) of pain in single-port laparoscopic surgery group were lower than that in conventional laparoscopic surgery group: (1.12 ± 0.21) scores vs. (3.56 ± 0.65) scores, and the difference was statistically significant ( P<0.05). The incision satisfaction rate in single-port laparoscopic surgery group was significantly higher than that in conventional laparoscopic surgery group: 90.32%(56/62) vs. 72.73%(56/77), and the difference was statistically significant ( P<0.05). Conclusions:Single-port laparoscopy can be safely and smoothly implemented in ovarian cystectomy, and can reduce postoperative pain, improve cell immunity, and have better cosmetic result.

Rate of cell apoptosis was detected by flow cytometry; mitochondrial membrane potential was measured by laser scanning confocal microscopy; the protein expressions of cleaved Caspase-3, Bax and Bcl-2 were detected by Western blot.Results Compared with the model group, rates of cell apoptosis in the different dosage groups decreased significantly; membrane potential of mitochondria increased; the protein expressions of cleaved Caspase-3 and Bax decreased; the expression of Bcl-2 increased; the ratio of Bcl-2 and Bax increased (P<0.05).Conclusion The ultra-filtration extracted from Angelica Sinensis Radix and Hedysari Radix can inhibit PC12 cell apoptosis induced by H2O2.

Objective To predict and identify T cell epitopes of major group 3 allergen derived from Dermatophagoides fari-na(Der f 3). Methods The T cell epitopes of Der f 3 were analyzed through the sequence analysis by using the bioinformatics online tools. The five predicted peptides of T-cell epitopes were artificially synthesized. The spleen lymphocytes were co-cultured with the five T cell epitopes by using the modified MTT method and the levels of IL-2,IFN-γ,IL-4 and IL-5 in the supernatant of the cultures were detected by ELISA. Results Five T cell epitopes of Der f 3 were predicted and three of which could pro-mote the proliferation of the mouse spleen lymphocytes. The secretions of IL-2 and IFN-γwere significantly induced and the se-cretions of IL-4 and IL-5 were significantly decreased by three of five prediction epitopes of Der f 3:37GDCPYQISLQSSSHFC-GG54,98IYQHENYDSMTIDNDVALIKLKTPMT123 and 164SELQRVDIDVVSREQCDQLYS184. Conclusion Three T cell epitopes of Der f 3 have been initially identified,which lays the foundation of the diagnosis and treatment of asthma.

Aim To investigate the effects of baicalin on cognitive function in global cerebral ischemia reper-fusion rats, and the probable mechanism involved. Methods Sixty male Sprague-Dawley(SD) rats were randomly divided into Sham operation group ( S group) , global cerebral ischemia reperfusion group ( I/R group) , global cerebral ischemia reperfusion + ba-icalin treatment group ( I/RB group) , twenty in each. Model was induced via the bilateral occlusion of the
common carotid arteries plus hemorrhagic hypotension. 12 h after reperfusion, rats in I/RB group were given baicalin (100 mg·kg-1 ) saline solution by intragas-tric administration twice per day for 7 days. Rats in S group and I/R group were given the corresponding dose of saline infusion at the same time. Morris water maze test was employed to detect spatial learning and memo-ry. BrdU immunohistochemistry was used to detect the proliferation of neural precursor cells ( NPCs ) in the
brain. Expression of COX-2 in the brain tissue was measured by Western blot. Results Compared to I/R group, baicalin improved spatial learning and memory damage ( P <0. 05 ) , increased the number of BrdU-positive cells in the DG and SVZ ( P<0. 01 ) , and re-duced the expression of COX-2 in the brain ( P <0. 01 ) . Conclusions Baicalin could ameliorate cog-
nitive function in the rats with global cerebral ischemia reperfusion, which might be associated with its inhibi-tory effects on the expression of COX-2 , thereby in-creasing the proliferation of NPCs in the brain.

Objective To explore the correlation between adiponectin/leptin(A/L) ratio and metabolic syndrome diagnosis in elderly men. Methods A total of 256 elderly men (≥60 years) were enrolled and divided into metabolic syndrome group(n= 109) and non metabolic syndrome group (n= 147). Serum levels of adiponectin and leptin were measured by radioimmunoassay (RIA) and the A/L ratio was calculated. Metabolic syndrome diagnosis is based on the definition provided by China Diabetes Society (CDS) in 2004. Results (1) In metabolic syndrome group versus non metabolic syndrome group, the serum levels of leptin and adiponectin were (10. 3±7.0) vs (6.8±4.9)μg/L and(7.8±5.6)g/L vs (9.5±5.9)g/L, and A/L ratio was 0. 94±0. 78 vs 2.15±2.13 respectively. (2) A/L ratio was positively correlated with high density lipoprotein cholesterol (HDL-C) and negatively correlated with body mass index (BMI), triacylglycerol (TG) and serum uric acid(P< 0. 001). (3) The higher value of A/L ratio, the lower possibility of metabolic syndrome. When the A/L ratio was more than 5, the incidence of metabolic syndrome was decreased to O(X2 =34. 891 ,P< 0.001). (4) The more components of metabolic abnormality, the lower value of A/L ratio(F= 10. 876,P<0. 001). Conclusions The A/L ratio may be useful in evaluating the extent of metabolic disorder and diagnosing metabolic syndrome in elderly men.
