Objectives To study the impact of initial age of treatment on testicular morphology and function in male pa-tients with multiple pituitary hormone deficiency using human chorionic gonadotropin (hCG) and human menopausal gonadotro-pin (hMG). Methods Patients with multiple pituitary hormone deficiency were treated with hCG and hMG while keeping other hormone levels normal. Correlations among their testicular volume, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and height, bone age were analyzed. Results After 6-month hCG and hMG treatment, the penis length of 54 male patients was significantly increased from (2.58 ± 0.69) cm to (4.19 ± 0.77) cm , and penis circumference was also increased from (3.71 ± 1.36) cm to (5.95 ± 1.26) cm;the testicular volume was increased from (1.76 ± 1.49) ml to (5.20±2.30) ml;height was increased from (147.01 ± 12.29) cm to (151.98 ± 11.52) cm and bone age was increased from (11.22 ± 2.71) years to (11.64 ± 2.72) years;the differences before and after treatment were statistically significant (all P<0.01). As the patients' age increased, their testicular volume and testosterone level increased slowly, and significant differences amongst each age group were found (P<0.05). The in-creased value of testicular volume, serum FSH and LH levels, and height growth tended to be negatively correlated to the initial age of therapy (r=-0.517~-0.334, P<0.05). Conclusions Early and proper treatment in male patients with multiple pituitary hormone deficiency using hCG and hMG improves testicular function and secondary sex characteristics.

OBJECTIVE:To compare the differences in the contents of water-soluble total protein,total phenolic acid and total polysaccharides among the water decoctions of crude Cibotium barometz and processed products and to illuminate the effect of pro-cessing on 3 kinds of components of C. barometz. METHODS:UV-visible spectrophotometry was adopted to determine the con-tents of water-soluble total protein,total phenolic acid and total polysaccharides in the water decoction of crude C. barometz and 4 processed products,namely sand-scorch C. barometz,yellow wine C. barometz,salt C. barometz and steamed C. barometz,at wavelengths of 590,760 and 489 nm respectively. RESULTS:The contents of water-soluble total protein in 5 samples were 4.03%,3.32%,3.13%,3.33% and 3.49%,those of total phenolic acid therein were 0.25%,1.34%,1.38%,2.34% and 1.41%,and those of total polysaccharides therein were 28.56%,36.06%,45.21%,49.60% and 49.01%,respectively. CONCLU-SIONS:All above processing methods have an effect to some degree on the contents of the 3 kinds of components of C. barometz, where the contents of water-soluble total protein are lower after processing,while those of total phenolic acid and total polysaccha-rides are higher thereafter.

Objective To investigate the expression and distribution of plasmacytoid dendritic cells(pDC) in peripheral blood and renal tissues in children with Henoch-SchSnlein purpura(HSP),and explore the role of pDCs in the pathogenesis of Henoch-Schtnlein purpura nephritis(HSPN).Methods Among the 40 children with HSP,28 cases were in the active phase(renal biopsy performed in 8 cases of them) and the other 12 in remission phase.Peripheral blood mononuclear cells were isolated,and the expression of pDC was detected by flow cytometry.The normal control group was established (n =15).Total RNA of peripheral blood was extracted and transcripted into cDNA.Sybr green dye based real-time quantitative PCR method was used to compare the expression(indicated as 2-△Ct value) of CXC motif chemokine 10 (CXCL10),CC chemokine ligand 5 (CCL5),chemokine CXC subfamily receptor 3 (CXCR3),CC chemokine receptor 5 (CCR5) in children with HSP and those in the controls.Immunohistochemistry labeling technique was used to detect the distribution of pDC in renal tissues from renal biopsy,and the normal controls were established (n =3).Results The expression percentage of pDC in peripheral blood in active phase was 0.051 ± 0.039,significantly lower than those in remission phase (0.181 ± 0.082) and the normal controls (0.166 ± 0.079) (P ＜ 0.000 1).Chemokines genes CXCL10 and CCL5 were overexpressed in peripheral blood ceils of acute phase HSP children,but chemokine receptors CXCR3,CCR5 were lowly expressed compared with normal controls.There was almost no expression of pDC in the normal control renal tissues,while pDC was infiltrated in glomeruli of HSPN children.Conclusions The number of pDC and chemokines' expression in peripheral blood is abnormal,and the pathogenesis of nephritis may be involved with the pDC in peripheral blood to migrate to the renal tissues.

APOBEC(apolipoprotein B mRNA-editing enzyme catalytic-polypeptide) family members were reported as innate immune molecules with anti-viral activity for many viruses, such as HIV and HBV.In order to understand the function of APOBEC, the APOBEC-3F and-3G were cloned, expressed, and the sub-cellular localization of them was detected.The genes of APBEC-3F and-3G were cloned from PHA-stimulated PMBC and expressed in the MDCK cell by transfection.The sub-cellular localization of APOBEC-3F and-3G were detected by immunofluorescence.APOBEC-3F and-3G were cloned by RT-PCR and confirmed by DNA sequencing.The immunofluorescence indicated APOBEC-3F and-3G were located in the cytosal.APOBEC-3F and-3G could inhibit HBV replication effectively in HepG2.2.15 cell.APOBEC-3F and-3G could not be trans-located into nuclear by nuclear location signal(NLS) or bi-NLS(B-NLS).These results will help the future research on the function of APOBEC.

Objective To explore the role of chemokines and ehemokine receptors in the etiopathog-enesis of diffuse proliferative lupus nephritis (LN). Methods ① Total RNA from the kidney tissues and peripheral blood cells of 12 patients with diffuse proliferative LN and 10 normal controls were prepared simultaneously and reverse transcribed into complementary DNA. Sybr green dye based real-time quantitative PCR method was used to compare the expression levels (indicated as-AACt value) of MCP-1, CCL19,CXCLg, CXCL10 and CCR2, CCR7, CXCR3. ② Immunofluoresceee labeling and immunohistochemical staining technique were used to observe the distribution of chemokines MCP-1, CCL19, CXCL9 and CXCL10 in normal and patients kidney tissues. Results The 4 chemokines genes (MCP-1, CCL19, CXCL9 and CXCL10) were consistently highly expressed in kidney tissues and peripheral blood ceils of diffuse proliferative LN patients compared with normal controls. The 2 chemokine receptors, CCR2 and CXCR3 were also overexpressed in peripheral blood cells of diffuse proliferative LN patients. There was nearly no expression of these 4 chemokine proteins in normal kidneys. But they were found in glomeruli of diffuse proliferative LN patients. Conclusion The expression of chemokines in the peripheral blood cells may be used as biomarkers for LN. Further study maybe lead to the development of specific drugs targeting at them for the treatment of systemic lupus erythematosus (SLE).

Background and purpose:Alpha fetoprotein (AFP)-producing gastric cancer (AFPGC) is considered to be a special type of gastric cancer. Currently, the effect on AFPGC is not as good as the common AFP-
negative gastric cancer. Therefore, it is very important to explore clinicopathological features of AFPGC cancer, to improve diagnosis and individualized treatment. This study is to investigate the expressions of hepatocyte growth factor receptor c (c-Met), vascular endothelial growth factor (VEGF), epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER-2) in the AFPGC.Methods:A total number of 44 cases of AFPGC (serum AFP≥10 μg/L) tissues were selected as a test group. There were 30 cases of serum AFP≥200 μg/L. This study collected 30 cases of gastric cancer with normal AFP and 30 cases of hepatocellular carcinoma with increased AFP (serum AFP≥200 μg/L) as 2 control groups. The cases of the 3 groups had the same clinical stage basically. The expressions of c-Met, VEGF, EGFR and HER-2, CD34 were detected by immunohistochemistry (EnVision staining method). Tumor microvessel density (MVD) was calculated by marking CD34, and the results were analyzed. The clinicopathologic parameters were recorded accurately: gender, age, highest level of serum AFP, tumor differentiation, tumor stage, tumor location, lymph node metastasis, liver metastasis, Lauren classiifcation, etc. These patients were followed up regularly. The clinical pathological features of AFPGC patients were investigated.Results:AFPGC clinical characteristics showed that, among 44 cases of AFPGC group, 86.36% (38/44) had lymph node metastasis, 54.55% (24/44) had hepatic metastasis, intestinal type was 36.36% (16/44), diffuse type was 56.82% (25/44), mixed type was 6.82% (3/44). The positive expression rates of c-Met protein in AFPGC, gastric cancer with normal AFP, hepatocellular carcinoma with increased AFP were 73.33% (22/30), 70.00% (21/30) and 53.33% (16/30), respectively. The positive expression rates of VEGF protein were 76.67% (23/30), 56.67% (17/30) and 66.67% (20/30), respectively. The positive expression rates of EGFR protein were 53.33% (16/30), 40.00% (12/30) and 73.33% (22/30), respectively. The “++ and +++” expression rates of HER-2 in AFPGC, gastric cancer with normal AFP and hepatocellular carcinoma with increased AFP were 38.64% (17/44), 23.33% (7/30) and 26.67% (7/30), respectively. The MVD values in AFPGC, gastric cancer with normal AFP and hepatocellular carcinoma with increased AFP were 23.03±10.24, 21.92±11.45 and 19.43±7.83, respectively. Compared with gastric cancer with normal AFP, expression of VEGF protein was signiifcantly higher in the AFPGC (P<0.05). Compared with hepatocellular carcinoma with increased AFP, the expression of c-Met protein was significantly higher in AFPGC (P<0.05).Conclusion:AFPGC is prone to lymph node metastasis and hepatic metastasis. The major part is the diffuse type in Lauren classiifcation. The positive expression rates of VEGF protein in AFPGC were signiifcantly higher than the gastric cancer with normal AFP. The positive expression rates of c-Met protein in AFPGC were signiifcantly higher than the hepatocellular carcinoma with AFP increased.

To study the influence of recombinant endostatin on angiogenesis and tumor growth of mice H22 hepatoma, tumor models were constructed by injecting H22 hepatoma cells into the leg muscle of mice. Recombinant endostatin was produced by gene engineering in E. coli. The recombinant protein was injected subcutaneously to treat transplanted hepatoma faraway. The weight of tumors was measured, and the changes of necrosis of tumor cells and vessel density were observed by immunohistochemistry. The results suggested that the growth of hepatoma models transplanted in the muscle of legs was suppressed by recombinant endostatin. The density of vascularity was decreased, but the necrosis of tumor cells increased. The inhibitory effect of recombinant endostatin on angiogenesis and tumor growth of hepatoma was not affected after chemotherapy.

CiteSpace 5.6.R5 was used for visual analysis of authors, countries, institutions, research hotspots and frontiers.Results:A total of 163 Chinese and 1,809 English publications were included. The number of literatures published at home and abroad shows an overall trend of growth. The United States has the largest number of publications, with China in seventh place. Domestic publishing institutions are mainly hospitals, led by Nanjing Children's Hospital affiliated to Nanjing Medical University. Foreign publications are mainly by university institutions, with Harvard University in the United States ranking first. Research teams led by authors including Gu Ying and Ravishankar C. are at the core in this field. The most discussed issues in China are mainly nutritional risk, nutritional support and nutrient research. The main target populations are ICU patients, premature infants, infants and children, etc. The forefront of research includes early enteral nutrition, prognosis and feeding intolerance. In foreign countries, studies mainly focus on epidemiology, nutritional support, malnutrition, risk factors, nutritional treatment, energy metabolism, obesity, clinical outcomes, etc. Main target population is special population, such as neonates with CHD, infants, children, patients after heart transplantation, etc. cohort studies and researches on overweight are at the frontier.Conclusions:The research on nutrition in CHD has attracted more and more attention. There are some differences in research content and hot topics between domestic and foreign studies. Therefore, we should strengthen the cooperation and exchanges among institutions, combine the advantages of CHD nutrition research in China, and strengthen the epidemiological study of CHD nutrition and the nutrition management of CHD key population, so as to further promote research development in this field.
