Objective To investigate the feasibility of laparoscopic splenectomy(LS).Methods Laparoscopic splenectomy was performed in 32 cases from June 1999 to December 2005 in this hospital.The splenic ligaments were disconnected using a harmonic scalpel and the pedicle of spleen was cut using the Endo-GIA system.After the spleen was mobilized,it was placed into an extraction bag,broken into small pieces,and removed from the extraction incision.Results The operation was successfully completed in 29 cases.The operation time was 60~270 min(mean,100 min),the amount of intraoperative blood loss was 30~1 000 ml(mean,230 ml),and the length of postoperative hospital stay,3~7 d(mean,5 d).No postoperative complications occurred.Conversions to open surgery were needed in 3 cases because of hemorrhage of the splenic pedicle,hemorrhage of the short gastric vessels,and extensive adhesion,respectively.Of the 22 cases of idiopathic thrombocytopenic purpura(ITP),the platelet count recovered to normal levels in 18 cases and kept unchanged in 4 cases.Of the 2 cases of hemolytic anemia,the hemoglobin levels were elevated after operation.Of the 4 cases of hypersplenism accompanying posthepatitic cirrhosis,the platelet count recovered to normal levels.Conclusions Laparoscopic splenectomy is a safe and feasible,especially for patients with hematologic diseases.

ABSTRACT:Objective To validate that relaxin can resist hepatic fibrosis at the cellular level and explore its molecular mechanism in order to provide experimental basis for the treatment of liver cirrhosis.Methods Cultured HSC-T6s were treated with different concentrations (20,50 and 100 ng/mL)of recombinant human relaxin-2 (RLX-2).The proliferation of HSC-T6 was measured by MTT colorimetric assay.The content of type Ⅰcollagen in the cell culture supernatant of each group was detected by ELISA at 48 h of drug intervention;RT-PCR was used to detect the mRNA expressions of CTGF and TGF-β1 in HSC-T6 at 48 h of drug intervention.Results RLX-2 inhibited the proliferation of HSC and reduced type Ⅰ collagen content of HSC cells.It also inhibited the CTGF mRNA expression of HSC,but did not have a significant effect on the expression of TGF-β1 mRNA. Conclusion In the experiment of culturing HSC-T6 in vitro,RLX-2 may play a role in rat liver fibrosis by inhibiting cell proliferation and type Ⅰ collagen and CTGF mRNA expressions.

Objective To construct a database for the genetic polymorphism of 19 STR loci in Han population from Hainan province. To investigate the application of 19 STR loci in the paternity testing. Methods The genotypes of 462 unrelated individuals in Hainan were detected with GoldeneyeTM 20A PCR Amplification Kit. 19-STR database was acquired, analyzed and evaluated in 283 paternity testing cases. Results No deviations of allele frequency from Hardy-Weinberg equilibrium expectations were found for Chi-square test (P>0.05). Observed heterozygosity (Hobs) varied between 0.603 and 0.914, total discrimination power (TDP) of 19 STR loci was more than 0.999999999999999, cumulative probability of exclusion (CPE) for triplet cases was 0.999999994. In all 283 paternity testing cases, triplets and duos were 170 and 113 respectively; there were 36 (12.7%) excluded cases comparing to 247 confirmed cases (87.3%). 14 mutation events were observed, and all were one-step mutation. Conclusion 14 out of 19 loci showed highly polymorphic in Han population from Hainan, and 19 STR system has high cumulative probability of exclusion and can meet the needs of paternity test of the local region. But mutation should be paid special attention to.

Objective To explore the variations of regeneration hormones after hepatectomy for liver cancer,and evaluate the relationship between the liver regeneration hormones and cancer recurrence.Methods The clinical data of 129 patients with primary hepatic carcinoma in our hospital from Dec 2004 to Dec 2005 were collected.The patients were divided into three groups according to their recurrent times,which were one-month recurrence group,6 months recurrence group and one-year recurrence group.And at the same time,40 cases of liver cancer that received TAE treatment were as contrast group.Serum HGF value was detected before operation and 1,3,7,10 and 14 days after operation.c-met,which is the receptor of HGF,was also detected as c-met mRNA and protein expression in cancer tissue and near-carcinoma liver tissue by semi-quantitative RT-PCR and Western Blot.The differences between the level of expression and the time of recurrence were compared,and the results were also compared with pathological indexes.Results Serum HGF value elevated after hepatectomy,the crest time appeared at about 10 days after the operation,and decreased after 14 days.The elevated values of HGF in large HCC tumors were markedly higher than those in small HCC tumors.The change of c-met mRNA and protein levels,revealed that the earlier the recurrence in both large and small HCC,the higher the c-met levels,and the higher the rate of vascular cancer emboli.Conclusions There is marked elevation of HGF level after hepatectomy in patients with liver carcinoma,and the over expression of c-met of the tumor may be related to its early postoperative recurrence.

Objective To evaluate the effect of laparoscopic herniorrhaphy(LHR)for inguinal hernia. Methods From December,1998 to December,2001, 176 patients with inguinal hernia were treated by LHR using laparoscopic purse string to ligate the neck of hernia sac and to place the intraperitoneal mesh.There were 160 patients with indirect inguinal hernia, 15 patients with direct inguinal hernia and 1 with indirect and direct hernia in this series. Results In this series,the mean operation time was 30 minutes, and was no intraoperative or postoperative complications; the hospital stay was 2～3 days. All the patients were followed-up for 10～36 months, only 2 recurrences(1.2%) were found. Conclusions LHR is a new herniorrhaphy which is safe and effective.The advantages of LHR are simple procedure, low complication rate, faster postoperative recovery, low recurrence rate.This operation should be widely adopted.

Terminology of persistent inflammation immunosuppression and catabolism syndrome (PICS) is developed based on the concept of multiple organ failure (MOF), which reflect that the preponderance is gradually reversed from pro-inflammation to anti-inflammation, and eventually the state of simultaneously persistent inflammation and severe immunosuppression appeared. Although the improvement of rescue technology and management increase the early survival rates of patient with critical illnesses, the long-term outcomes of most patients are not optimistic. The patients with PICS are difficult to treat or prevent, and are likely to indolent death and have a rising incidence, which is an important challenge to the intensive care unit (ICU). The paper review the understanding of PICS, summarize the specific changes of immune system in PICS, and explore the immunological markers for early recognition of PICS and judgment of immune state in order to provide new thinking for prevention and control of PICS.

Objective To investigate the association between interleukin-23 receptor (IL-23R) gene rs1343151 single nucleotide polymorphism and ankylosing spondylitis (AS) in Chinese Han patients. Methods The genotypes of IL-23R SNP was detected in 104 Chinese AS patients and 95 ethnically matched blood donors by TaqMan probe assays. The allele and genotype frequencies and risk factors of AS were analyzed by Chi-square test in both groups. Results The rs 1343151 genotypes in AS patients consisted of homozygote C/C (90.4%),C/T (9.6%), while The rs1343151 genotypes in the controls were. composed of C/C (91.6%), C/T (8.4%). No significant difference was found in the distribution of rs1343151 genotypes between these two groups (x2=0.086, P>0.05). The frequency of rs1343151 allele in AS patients was also not significantly increased when compared with the control group (x2 =0.082,P>0.05). Conclusion There may be no association between the IL-23R gene rs1343151 SNP and ankylosing spondylitis in Chinese Hart population.

Panax notoginseng (PN) is one of the commonly used clinical medicines for cardiovascular diseases and possesses a variety of pharmacological effects. P. notoginseng saponins (PNS) are the most important bioactive components in PN. The purpose of this study was to explain the mechanism of PNS on molecular network level. 18 targets of the main medicinal ingredients of PNS were gained by virtual screening based on pharmacophores and data mining. A protein interaction network of PNS was constructed with 189 nodes and 721 interactions. By a graph theoretic clustering algorithm Molecular Complex Detection (MCODE), 14 modules were detected. Gene ontology (GO) enrichment analysis of the modules demonstrated that the roles of PNS played in cardiovascular disease related to multiple biological processes, which could represent the characteristics of traditional Chinese medicine (TCM) as a whole to regulate the disease. The results showed that the blood circulation and hemostasis efficacy of PN related with the biological processes such as positive regulation of cAMP metabolic and biosynthetic process, platelet activation and regulation of blood vessel size, regulation of T cell proliferation and differentiation and so on. Therefore, the module-based network analysis will be an effective method for better understanding TCM.
