Objective To study the promotive effect of chitosan liquid on wound healing.Methods Wound model was established on the back of 60 rats,which were classified into 3 groups to be treated with topical chitosan liquid (group A),basic fibroblast growth factor (group B),and sodium chloride physiological solution (group C),respectively.The time required for the healing of wound was recorded.Regenerated tissues were resected from the rats on day 3,7 and 14 after the establishment of wound model,and observed with light microscopy.Results The time required for the healing of wound was 17.3 ± 1.35 days in group A,18.2 ± 1.15 days in group B,and 24.0 ± 1.37 days in group C.For the time required for the healing of wound,no significant difference was observed between the group A and B (P ＞ 0.05),but group C significantly differed from group A and B (both P ＜ 0.05).Chitosan liquid accelerated the generation of capillary sprouts and vascular endothelial cells at the early stage of wound healing,promoted the production of fibroblasts and collagen fibers at the middle stage,and improved the organization of collagen fibers at the late stage.Conclusion Chitosan liquid exerts a promising promotive effect on wound healing.

BACKGROUND:The relationship between the occurrence time and clinical symptoms of bone marrow edema in nontraumatic femoral head necrosis is stil controversial. OBJECTIVE:To evaluate the relationship of bone marrow edema in nontraumatic femoral head necrosis with Association Research Circulation Osseous (ARCO) staging and pain grading. METHODS: Forty-eight patients with nontraumatic femoral head necrosis (58 hips) were confirmed to have bone marrow edema on MRI T1 weighted images and T2 fat suppression images. Then, the patients were graded according to the MRI Classification Method reported by Zhao Pei-rong, the ARCO Staging System and Harris hip score for pain grading. We analyzed the correlation of bone marrow edema with ARCO staging and pain grading. RESULTS AND CONCLUSION:The incidence rate of bone marrow edema in ARCO I-III was increased in sequence, and the difference was statisticaly significant (χ2=27.69,P=0.001); the average rank of bone marrow edema in ARCO I-III was increased significantly (χ2=19.947,P=0.000). The incidence rate of bone marrow edema also increased among different pain grading, and the difference was statisticaly significant (χ2=57.0, P=0.000); the average rank of bone marrow edema among different pain grading was increased significantly (χ2=174.0,P=0.000). The presence and aggravation of bone marrow edema indicate the enlargement of necrosis area and the aggravation of symptoms in patients with nontraumatic femoral head necrosis, which can be used as an auxiliary index for the appraisal of disease progression.

Objective To study the expression of fascin, an actin bundling protein associated with cell motility, and the relationship with ER negative breast carcinoma.Methods Comparasion of the expression of fascin, estrogen receptor (ER) and proliferative cell nuclear antigen (PCNA) determined by immunohistological method was made on 84 specimens of primary breast carcinomas. Results The diffuse staining of fascin in cancerous cell cytoplasm was noted. Only 3 of 53 breast carcinomas with ER positive showed fascin positive expression (5.67%); in contrast, 21 of 31 carcinomas with ER-negative showed positive expression(67.7 %) (P

Objective　To understand the trends of serum lipid concentration and the prevalence of dyslipidemia in adults aged 35 years and older, and to compare the regional differences in lipids. Methods　Based on the data of Anhui Province in the Early Screening and Comprehensive Intervention Project for High-risk Groups of Cardiovascular Disease in China from 2017 to 2021, the change trend of blood lipid level and the prevalence rate of each region were plotted according to the year and different regions in the province, and the influencing factors of dyslipidemia were analyzed by multivariate regression model. Results　The overall average levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and non-high-density lipoprotein cholesterol (non-HDL-C) demonstrated an increase followed by a slight decrease with age annually, while the levels of high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG) fluctuated minimally. From 2017 to 2020, TC levels improved annually but increased again in 2021. Similar to TG and non-HDL-C, the average LDL-C level decreased annually from 2017 to 2019, while rebounded in 2020 and 2021 compared with the previous three years. In contrast, the HDL-C level continued to decline. With the exception of HDL-C, the overall blood lipid levels in the northern Anhui (n=31 716) were higher than those in the southern Anhui (n=50 681), and the lowest levels were found in the central Anhui (n=38 246). The prevalence of hypercholesterolemia (7.400%, 2 347/31 716), high LDL-C (5.228%, 1 658/31 716), low HDL-C (9.935%, 3 151/31 716), hypertriglyceridemia (18.212%, 5 776/31 716), and high non-HDL-C (5.789%, 1 836/31 716) were highest in the northern Anhui. Age, region, senior high school or above, smoking, drinking, systolic blood pressure, blood glucose, and body mass index were independent factors for dyslipidemia (P<0.05). Conclusion　The blood lipid level and prevalence of dyslipidemia in adults aged ≥35 years in Anhui Province have not yet reached an ideal control level, especially in the northern part of Anhui Province where there is a need for enhanced awareness and timely intervention measures for lipid-related diseases to effectively extend the life expectancy of residents.

BACKGROUND: Tumor recurrence in liver transplant recipients greatly affects prognosis of liver transplantation with hepatocellular carcinoma (HCC). How to prevent tumor recurrence has aroused increasing attention. Arsenious acid chemotherapy is considered effective on treating moderate or advanced liver cancer, but its utilization following liver transplantation remains few. OBJECTIVE: To explore the role of arsenious acid on tumor recurrence in liver transplant patients with primary HCC extending Milan criteria. RESULTS AND CONCLUSION: All patients were routinely followed up for 3-32 months. Thirty recipients were presented with tumor recurrence, 16 in the chemotherapy group and 14 in the non-chemotherapy group. Tumor recurred in lung, liver graft and bones in most cases. The total recurrence rate was similar in these two groups, but chemotherapy could delay recurrence after transplantation (P=0.026). There was no significance in 6-month, 1-year survival rate between two groups, but the 2-year survival in the chemotherapy group was higher (P=0.037); 6-month tumor-free survival rates in the two groups had no significance, 1-year and 2-year tumor-free in the chemotherapy group were significantly higher than those in the non-chemotherapy group (P=0.030, 0.023). Intravenous arsenious acid chemotherapy can delay tumor recurrence and prolong survival in liver transplant patients with HCC extending Milan criteria.

0.05).The accuracy of Borrmann type classification in 14 cases of advanced gastric carcinoma undergone gastrectomy was 92.8%.Conclusion The gastric carcinoma detection rate with NHSCT is similar to that with fibro-gastroscopic or double-contrast barium examination.The direct and indirect signs of gastric carcinoma can be found and the Borrmann type classification can be made by NHSCT.However,the non-contrast enhancement scanning is limited for the early gastric carcinoma detection,and can be improved by contrast enhancement scanning.

Objective Sirolimus is a new, potent immunosuppreasant considered to be nonnephrotoxic. There is limited experience with the use of sirolimus in liver transplant recipients. This study was to investigate the clinical experience of conversion from tacrolimus-based to sirolimus-based immunosuppression in liver transplant recipients. Patients switched to cyclosporine-based immunosuppression during the same period were also enrolled as controls. Methods This retrospective study examined liver transplant recipients who had been switched from tacrelimus-based to sirolimus-based or cyelosporine-based immunosuppressive therapy between January 2004 and January 2008 in the First Affiliated Hospital of Sun Yat-sen University. Patients were divided into 2 groups: those switched to sirolimus-based immunosuppression (group A; n=32); and those switched to cyclosporine-based immunosuppression (group B; n=15). Results The rate of successful conversion was 34.5% in group A (10/32) compared with 45.5% in group B (7/15); this difference was not statistically significant (P>0.05). After conversion, renal function in patients in group A remained normal, while the renal function in patients in group B become abnormal 4 months after conversion (P<0.05). In group A, some simlimus-associated adverse effects occurred but were mild and easy to control. Conclusion Sirolimus can be used safely in place of tacrolimus in liver transplant recipients.

Objective To explore the diagnostic value of MSCT in tumors of intra-abdominal cryptorchidism in children.Methods MSCT findings of 8 children with tumors of intra-abdominal cryptorchidism confirmed by surgery and pathology were analyzed retrospectively.Results Six tumors located in the right,2 (1 tumor of left cryptorchidism turned to the right abdominal) in the left.Eight children showed ovoid soft tissue tumor in abdomen.Three children displayed the long axis of the tumors consistent with regular descending course of embryonic testes.Six teratomas manifested as the cystic and solid mass with fat,calcification (ossification) insidey.Two yolk sac tumors manifested as the large cystic and solid mass with irregular necrosis and abundant tumor vessels.Conclusion The pathologic types of tumors for intra-abdominal cryptorchidism in children are different from adult.Most of them are teratomas or yolk sac tumors,and have some characteristics in MSCT.MSCT is helpful in diagnosis of tumor for intra-abdominal cryptorchidism with medical history.

Objective To evaluate the impact of steatotic hepatic grafts on postoperative early liver function and prognosis.Methods Clinical data of 35 cases receiving steatotic liver grafts in our hospital were retrospectively analyzed.The donor liver grafts were divided into 3 groups based on the degree of fatty infiltration(＜20%group,20%～40%group,≥40%group).Results were compared with that from control normal grafts(41 cases).Liver function parameters including AST,ALT,TB,PT on the day of surgery and 1,2,3,7 days later were monitored among the 4 groups,as well as the incidence of delayed nonfunction (DNF),and 3 and 6 months patient survival rate.Analysis of the correlation between degree of donor steatosis and liver function after operation was carried out.Resuits There was significant difference in postoperative ALT、AST、TB、PT level between≥40%group and 20%～40%group,and between 20%～40%and group＜20%group.There was no significant difference among the groups in DNF occurrence rate and 3 month.6 month patient survival rate.Correlation analysis suggested that the degree of donor steatosis was positively correlated with the damage of liver function.Conclusions Grafts with≤20% steatosis was safe,whereas≥20% especially ≥40% steatosis carries a high risk of posttransplant liver dysfunction even delayed nonfunction.
