Objective:To observe the clinical efficacy of Yishen Tongluofang in treating oligosperm type male infertility with kidney deficiency and blood stasis syndrome and explore its effect on serum sex hormones and seminal plasma microenviro. Method:One hundred and four patients were randomly divided into observation group and control group with 52 cases each. Patients in control group took compound Xuanju capsules orally， 3 capsules/time， 3 times/day. Patients in observation group took Yishen Tongluofang， 1 dose/day. Treatment courses continued three months and followed up for three months in both groups. The pregnancy situations of spouses within six months were recorded. Examination of semen parameters before and after treatment and score of kidney deficiency and blood stasis syndrome were conducted. The levels of seminal plasma zinc， fructose， elastase， acid phosphatase and <italic>α</italic>-glucosidase， serum follicle stimulating hormone （FSH）， luteinizing hormone （LH）， prolactin （PRT） and testosterone （T） were detected before and after treatment. Result:During the observation period of six months， the pregnancy rate of spouses in the observation group was 22.00%， higher than 10.00% in the control group， but the difference was not statistically significant （<italic>χ</italic>²=2.678，<italic>P</italic>>0.05）. The clinical efficacy in the observation group was better than that of the control group （<italic>Z</italic>=2.326，<italic>P</italic><0.01）. Sperm concentration， sperm motility， sperm motility， normal morphological sperm and linear movement speed of the observation group were all superior to those of the control group<italic> </italic>（<italic>P</italic><0.01）. The levels of zinc and fructose in seminal plasma of the observation group were higher than those of the control group （<italic>P</italic><0.01）， and the score of kidney deficiency and blood stasis syndrome was lower than that of the control group （<italic>P</italic><0.01）. Serum FSH， LH and PRT levels in the observation group were lower than those in the control group （<italic>P</italic><0.01）， and the T level was higher than that in the control group （<italic>P</italic><0.01）. The seminal plasma elastase of the observation group was lower than that of the control group， while the levels of acid phosphatase and <italic>α</italic>-glucosidase were higher than those of the control group （<italic>P</italic><0.01）. Conclusion:Yishen Tongluofang can significantly improve sperm parameters， regulate the level of sex hormones and seminal plasma environment in patients with oligosperm type male infertility， and improve the tendency of spouse pregnancy.

Effects of clonal integration on the proximal and distal ramets of Cynodon dactylon under shade stress

ABSTRACT In a pot experiment, clonal ramets of Cynodon dactylon, a stolon herbaceous plant, were treated with heterogeneous lighting. Proximal ramets (elder ramets) were subjected to shade stress at three different degrees, and stolons between proximal and distal ramets of each pair were treated in a connected or severed manner. Results showed that in moderate shade stress, the number of ramets and leaves, biomass, net photosynthetic rate (Pn), maximum quantum yield (Fv/Fm), effective quantum yield of PSII (ФPSII), and soil and plant analysis development values (SPAD) of proximal ramets were significantly reduced, regardless of whether stolons were kept intact or severed. However, the growth of distal ramets was not significantly influenced, and keeping the stolons intact also did not bring apparent benefits for the whole clonal fragments. These results show that clonal integration does not help alleviate the shade stress suffered by proximal ramets and the costs of distal ramets and does not significantly influence the whole clonal fragments. The possible reasons are that distal ramets may be at the cost of metabolism for resource transportation when the proximal ramets suffer from shade stress; thus, clonal integration is not favorable.

Risk factor analysis andmanagement of massive perihepatic blood accumulation after liver transplantation / 第二军医大学学报

Objective To explore the risk factors and to develop the management methods of massive perihepatic blood accumulation after liver transplantation. MethocSs Clinical data of 117 patients, who received performed ortho topic liver transplantation in the Department of Biliary Tract Surgery (I) of Eastern Hepatobiliary Surgery Hospital of Second Military Medical University from Mar. 2004 to Apr. 2007, were retrospectively studied to analyze the mdependent risk factors associated with the occurrence of massive perihepatic blood accumulation by univariate analysis andmultivariate analysis, and to summarize the corresponding treatment methods. Results Twelve of 117 cases died ln the perioperative period, and 105 caseswere lncluded in this study. Among 105 cases, 9 (8. 57%) had postoperative massive perihepatic blood accumulation accompanied by aggravated yellowing of the skin and sclera, elevated whole blood leukocyte count and neutrophil proportion in a short period of time, and impaired liver function. Univariate analysis showed the massive perihepatic blood accumulation was associated with a history of upper abdominal surgery (P=0. 001), pre-operative hemoglobin (P= 0. 031), pre-operative leukocyte count (P= 0. 001), pre-operative platelet count (P<0. 001) and post-operative bile leakage (P=0.001); Multivariate analysis showed a history of upper abdominal surgery (P=0. 008, 0R=15. 000) and post-operative bile leakage (P=0. 034, OR=20. 770) were independent risk factors for massive perihepatic blood accumulation. Conclusion The main methods to prevent massive perihepatic blood accumulation include knowing the history of upper abdominal surgery m patients, strictly protecting the blood supply of bile duct, accurate anastomosis and preventing bile leakage. Puncture or removal of hematocele timely is effective for massive perihepatic blood accumulation.

Chemokine CCL20 and malignant tumors / 肿瘤

Chemokine is a kind of cytokine that induces cell transport to inflammation sites. It plays an important role in controlling the differentiation, development and directed migration of immunocytes. CCL20 is one of the important members of chemokine family, and it belongs to CC subfamily. Its receptor is CCR6. CCL20 can be expressed in activated monocytes, T lymphocytes, dendritic cells and endothelial cells, and CCR6 can be expressed in liver, lung, and lymphoid tissues. The expression of CCL20 can be induced by tumor necrosis factor α (TNFα), interleukin 1β (IL-1β), IL-17, CD40 ligand and interferon γ (IFN-gamma;). In summary, CCL20 plays an important role in tumor growth, invasion and metastasis (mainly refers to intrahepatic metastasis). Copyright© 2011 by TUMOR.

Study on the determinants of 'signing agreements' to establish smoke-free homes among 2019 parents of the secondary school students / 中华流行病学杂志

<p><b>OBJECTIVE</b>To explore the determinants of 'signing a agreement for establishing smoke-free homes' among the parents of secondary school students.</p><p><b>METHODS</b>2019 parents were surveyed with self-administered questionnaires on their socio-demographic characteristics, smoking behaviors, attitude toward tobacco control at home and related data of their children. At the same time, parents were asked to sign an agreement for making the 'home as smoking-free'. 'Parents signing the agreement' was defined as dependent variable (0=no, 1=yes), and parent's age, gender, educational level, etc. were defined as independent ones. Multi-variant logistic regression analysis was conducted for identifying the determinants of the parents to sign an agreement for establishing 'smoking-free homes'.</p><p><b>RESULTS</b>Of the 2019 surveyed parents, 1047 (51.86%) had signed the agreement including 49.25% of the fathers and 55.73% of the mothers. The results from multi-variant logistic regression analysis indicated that father's 'signing action' was significantly associated with (a) their intention of carrying out the agreements (OR = 3.37), (b) to teach their children about the consequence between smoking and health (OR = 2.10), (c) knowing tobacco control program at school (OR = 1.38), (d) reading tobacco control material provided by school (OR = 1.38), (e) being current smoker (OR = 0.53) compare to that the mother's 'signing action' was significantly associated to (a) intention to carrying out agreements (OR = 2.36), (b) teaching children not to smoke (OR = 2.22), (c) reading tobacco control material provided by school (OR = 1.57).</p><p><b>CONCLUSION</b>Changing parental cognition and attitude toward smoking was beneficial to promote parental participation in tobacco control campaign and to establish 'smoking-free homes'.</p>
