Objective To discuss the value of laparoscopic total extraperitoneal repair(TEP) for inguinal hernia.MethodsBetween 2005 and 2007,82 consecutive patients with inguinal hernia at 97 sides underwent TEP by laparoscopy in our hospital.Among the cases [76 men and 6 women with a mean age of 52 years(21 to 88)],9 had unilateral direct inguinal hernia,50 showed unilateral indirect inguinal hernia,and 9 suffered from bilateral indirect inguinal hernia,6 cases were found having bilateral indirect inguinal hernia complicated with direct hernia,and 8 were recurrent cases of indirect inguinal hernia.Results In the patients,5 showed massive postoperative abdominal adhesion;one of them was converted to open surgery because of severe injury to the peritoneum,the other 4 were treated by continuous suture using 5-0 absorbable thread.The operation time for laparoscopic surgery ranged from 30 to 180 minutes(58 minutes for unilateral operation,and 97 minutes for bilateral operation on average).No patient needed analgesics after the procedure.The mean hospital stay for this series was 7 days(range: 4 to 12).Nine patients developed seromas of the scrotum,and was then cured by local drainage and physical therapy.The 82 patients were followed up for 13 to 38 months with a mean of 26 months,during which no one had recurrence.Conclusion As a safe and minimally invasive procedure,which leads to less trauma and pain,as well as quick recovery,TEP is especially suitable for patients with recurrent or bilateral hernias.

[Objective] To investigate the relation among the polymorphism of interleukin-8 (IL-8) gene A-251T and apolipoprotein E (ApoE) gene with late-onset Alzheimer's disease (LOAD). [Methods] Polymerase chain reaction and restrietive fragment length polymorphism (PCR-RFLP) were used to detect the polymorphism distribution of IL-8 gene A-251T and ApoE gene of 185 people in Han ethnicity of Guangdong province (study group: 88 LOAD patients, eontrolled group: 97 people). The correlation of these genes was analyzed. [Results] (1) The differences of genotypes and alleles of IL-8 gene A-251T between study group and controlled group had no statistical significance. (2) The frequency of ApoE 64 allele in study group was significantly higher than that in controlled group, as risk factor of LOAD (OR=2.272, P=0.003). (3) Study group and controlled group were both divided into two groups by carrying ApoE ε4 allele or not. The differenees of IL-8 genotypes were no significant whether in carrying ApoE ε4 allele group or not (carrying ε4 group: P=0.965; no carrying ε4 group: P=0.523). [Conclusion] It is suggested that lL-8 gene A-251T polymorphism perhaps has no relation with LOAD and has no interaction with ApoE ε4 allele.

Objective To investigate the relationship between C1773T polymorphism of LDL receptor gene (LDLR) and cerebral hemorrhage and the impact of C1773T polymorphism of LDLR on the levels of serum lipids in Chinese Han in Changsha, Hunan province. Methods Two hundred seventy-three cerebral hemorrhage patients and 140 normal controls were recruited in the present study. The C1773T polymorphism of LDLR was analyzed by SNaPshot and direct DNA sequencing. The triglyceride (TG), total cholesterol (TC), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C) levels were examined using oxidase method. Results The CC, CT and TT genotype frequencies of LDLR polymorphism were 0.703/0.278/0.019、0.707/0.250/0.043 and the allele C and T frequencies of LDLR polymorphism in the cerebral hemorrhage group and the control group were 0.842/0.158,0.832/0.168 respectively. The differences in genotype and allele frequencies of LDLR polymorphism were no significant between cerebral hemorrhage group and the control group (P>0.05). There were no significant differences in the levels of lipids among the CC, CT and TT genotype in either cerebral hemorrhage group or the control group (P＞0.05). Conclusions The LDLR-C1773T polymorphism may not be associated with cerebral hemorrhage nor be related to hyperlipemia in Chinese Han in Changsha.

OBJECTIVE: To explore the association between apolipoprotein AI (ApoAI) gene rs12721026 polymorphism and cerebral hemorrhage (CH) in Changsha Han population, and to evaluate the effect of rs12721026 polymorphism on plasma lipid levels. METHODS: A total of 273 patients with CH and 140 healthy controls were collected. The rs12721026 polymorphism of ApoAI was analyzed by SNaPshot genotyping analysis and DNA sequencing. The total cholesterol (TG), triglyceride (TC), HDL-C and LDL-C were examined by oxidase method. RESULTS: There was no significant difference in the genotype and allele frequencies of rs12721026 polymorphism between the CH group and the control group (P>0.05). Both in the CH group and in the control group, the level of HDL-C of the TT gene type of rs12721026 was significantly higher than that of the GT/GG gene type (P<0.05). There was no significant difference in the levels of TG, TC and LDL-C among different subgroups of gene types. CONCLUSION There may be no association between apoAI gene rs12721026 polymorphism with CH in Changsha Han population, which may still influence the HDL-C levels.

Objective To analyze the clinical efficacy and safety of compound Qinghuang powder (compound QHP) for treatment of myelodysplastic syndromes (MDS) and its association with blood arsenic concentration (BAC). Methods 40 patients with MDS were treated with compound QHP, and the clinical efficacy, safety, and its association with BAC were evaluated after treatment for 6, 9 months, respectively. Results After treatment for 6 months, the rate of hematology improvement was 32.5 % (13/40), and the effective rate was 87.5%(35/40). 21 cases depended on the blood transfusion before treatment, after treatment 6 cases completely got rid of blood transfusion and the blood transfusion of another 6 cases was decreased by more than 50 %. The absolute neutrophil count was increased from (0.50±0.13)×109/L to (0.93±0.33)×109/L (t= 4.130, P= 0.0008). The hemoglobin content was increased from (71.06±14.82) g/L to (80.41±27.35) g/L (t= 2.233, P= 0.0321). After treatment for 9 months, 76.2 % (16/40) of the patients got rid of blood transfusion or blood transfusion reduction was more than 50%. The platelet count was increased from (45.04 ± 24.38)×109/L to (60.65±29.46)×109/L (t= 2.241, P= 0.0335). The incidence of abdominal pain and diarrhea after treatment for 1, 3 and 6 months were 12.5 % (5/40), 10.0 % (4/40) and 5.0 % (2/40), respectively, all belonging to mild level . Before treatment , there were 12 patients with abnormal liver function , including 6 cases back to normal after treatment, and 6 cases of significantly relieved, without new case with abnormal liver function. Before treatment, there were 10 cases with abnormal myocardial enzymes, including 1 cases back to normal after treatment and 9 cases significantly relieved, without new case with abnormal myocardial enzymes. No patient with abnormal renal function was observed before and after treatment. The BAC was (7.71±5.65) μg/L before treatment, which was significantly lower than that of 1, 3 and 6 months [(29.27±9.07)μg/L, (27.79 ±10.18) μg/L and (31.98 ±12.55) μg/L respectively, all P< 0.0001]. There was no significant change of BAC among the patients after treatment for 1, 3 and 6 months (P> 0.05). The BAC in efficacy group [(33.48 ±12.56) μg/L] was significantly higher than that in non-efficacy group [(21.46 ±6.00) μg/L] (t=2.089, P=0.035). 12.5% (5/40) of the patients had mild gastrointestinal side effects after treatment for 1 month, while the BAC of them [(16.93 ±1.80) μg/L] was significantly lower than that in patients without gastrointestinal side effects [(31.78±1.39 ) μg/L, P<0.0001]. The occurrence rate of abdominal pain and diarrhea was decreased after treatment for 3 and 6 months, while the BAC was increased gradually. Conclusions Compound QHP is effective in the treatment of MDS with mild adverse reactions. There is no damage to the heart, liver, and renal function. Besides, it shows that reducing the gastrointestinal adverse reactions and maintaining the effective concentration of BAC play a significant role in the effect of compound QHP in the treatment of MDS.

Objective To search for application ways for the safe and effective clinical methods of arsenic-containing Compound Qinghuang Powder (Compound QHP) for the treatment of myelodysplastic syndrome (MDS). Methods Totally 200 patients with MDS were included in the study and treated with Compound QHP. After one-month treatment, the 60 patients with the blood arsenic concentrations <20 μg/L were randomly divided into control group and treatment group, with 30 cases in each group. Control group was given stable treatment, while the treatment group was given increased dose of realgar; blood arsenic concentration was detected monthly; realgar 0.1 g was increased each time until blood arsenic concentrations ≥20 μg/L and realgar ≤0.3 g/d. The blood arsenic concentration, clinical efficacy and safety in the two groups were observed. Results Totally 24 cases in each group were included for evaluation finally. The average blood arsenic concentration of treatment group was significantly higher than those of control group (P<0.05). The rate of hematologic improvement was significantly higher in treatment group (54.2％, 13/24) than that in control group (29.2％, 7/24) , with significant difference (P<0.05). The Hb, ANC, and PLT significantly increased in treatment group after treatment (P<0.05). There was no significant difference of incidence rate of adverse reaction observed between treatment group and control group (P>0.05). Conclusion In application of Compound QHP, the blood arsenic concentration can be monitored to adjust the daily dose of realgar, thus to increase the effective blood arsenic concentration, and then improving efficacy without increasing the clinical toxicity.

Objective To investigate the effect of nucleotide-binding oligomerization domaincontaining protein 1 (NOD1) on pyroptosis in hepatic ischemia-reperfusion injury.Methods An animal model of ischemia-reperfusion injury was established.Thirty healthy,male,and clean C57 BL mice were randomly divided into sham operation group (sham group) and ischemia-reperfusion group (IR,including 2 h,6 h,12 h,24 h subgroups),6 per group.Serum ALT and AST levels in each group were measured by blood biochemistry.HE staining and TUNEL were used to observe the pathological changes of liver and hepatocyte apoptosis.Immunohistochemistry was used to detect the expression and distribution of NOD1 in each group.Western blotting was used to detect NOD1,MM2,pro-Caspase-1 and active-Caspase-1 expression.NOD1 siRNA and empty control siRNA were transfected into AML12 cells,then the hypoxia/reoxygenation model was established and cells were collected to detect the expression of NOD1,AIM2 and active-Caspase-1.Results The ALT and AST levels in IR group were significantly higher than those in sham group,and peaked at IR 12-h subgroup (P＜0.05).HE staining showed that hepatic injury was the most severe at 12 h after reperfusion.TUNEL results showed that the number of apoptotic cells was the greated at 12 h after reperfusion.Western blotting showed that NOD1 protein expression was highest at 12 h after reperfusion.With the prolongation of reperfusion time,the expression of AIM2 and active-Caspase-1 gradually increased,and that of pro-Caspase-1 gradually decreased.The expression of NOD1,AIM2 and activeCaspase-1 decreased after transfection of NOD1 siRNA into AML12 cells.Conclusions NOD1 promotes liver ischemia-reperfusion injury,which may be related to NOD1 promoting liver injury by activating pyroptosis.

Objective To explore the role of miR-137 in the proliferation and migration of hepatocellular carcinoma (HCC) cells by regulating Notch1 and mediating autophagy.Methods The human SMMC7721 hepatoma cell line was transfected with miR-137 mimics,miR-137 inhibitor and Notch1 interfering RNA (siRNA),and divided into normal control group (NC group),miR-137 mimics group,miR-137 inhibitor group,Notch1 siRNA group.The expression levels of miR-137 and Notch1 mRNA after the transfection were detected by RT-PCR in SMMC7721 cells.Transwell experiments were performed to analyze the effect of miR-137 and Notch1 on the migration and invasion of SMMC7721 cells.The expression levels of β-catenin and vimentin in SMMC7721 cells were detected by immunohistochemistry.The number of autophagosomes was detected by double labeled adenovirus.Western blot was utilized to detect the expression of Notch1,E-Cadherin,N-Cadherin,vimentin,P62,and LC3.Results The results of RT-PCR showed that the relative expression level of Notch1 in miR-137 inhibitor group (5.71 ± 0.45) was significantly higher than that in miR-137 mimics group (0.21 ± 0.06) with statistical significance (P ＜ 0.05).The Transwell experiments showed that there were fewer invasive metastatic hepatoma cells in miR-137 mimics group (66.00 ± 4.55) and Notch1 siRNA group (88.00 ± 6.78) than that in the miR-137 inhibitor group (515.00 ±35.12) (P ＜0.05).The expression levels of β-catenin in miR-137 mimics group and Notch1 siRNA group were significantly increased and the expression level of vimentin was decreased (P ＜ 0.05).The results of autophagy double labeled adenovirus test showed that the number of autophagosomes in miR-137 mimics group (5.50 ± 3.70) was significantly fewer than that in miR-137 inhibitor group (32.75 ± 4.11),and the difference was statistically significant (P ＜ 0.05).The expression levels of Notch1,N-cadherin,vimentin,and LC3 protein in miR-137 mimics group were much lower than that in miR-137 inhibitor group and NC group,and the expression levels of E-Cadherin and P62 protein were greatly increased.The expression level of Notch1,N-cadherin,and LC3 protein in Notch1 siRNA group were significantly lower than that in NC group,and the expression levels of E-cadherin and P62 protein were much higher than that in NC group.Conclusion MiR-137 can inhibit the proliferation,migration and invasion of HCC cells by inhibiting the expression of Notch1 and autophagy,which may become a new target for the treatment of HCC.

MAIN OUTCOME MEASURES: The 6 common diseases were observed among the elderly: Hyperplasia of prostate, abnormal audition, cartaract ,osteoarthritis, fracture and constipation.RESULTS:Totally 1434 elderly entered the stage of result analysis.①The incidence of hyperplasia of prostate in the males from the urban areas was lower than that in the rural areas (61.4％,65.7％, P ＜ 0.01 ). ② The incidence of abnormal audition among the elderly from the urban areas was lower than that in the rural areas (53.9％,64.7％,P ＜ 0.01).③ The incidence of cataract of the two eyes in the elderly from the urban areas was higher than that in the rural areas(46.4％,44.4％, P ＜ 0.01). ④ The incidence of osteoarthropathy in the elderly from the urban areas was higher than that in the rural areas (24.4％,14.9, P ＜ 0.01). ⑤ The incidence of fracture in the elderly from the urban areas was higher than that in the rural areas (14.2％,9.1％, P ＜ 0.05). ⑥ The incidence of constipation of the elderly in urban areas was lower than that in the rural areas(18.2％,23.0％,P ＜ 0.05).CONCLUSION:There is a difference between the elderly from the urban areas and the rural areas in hyperplasis of prostate,abnormal audition, cataract, osteoarthropathy, fracture and constipation, and this is related with the economy, nutrition, medical conditions and cultural traits.Therefore, attention should be attached to nutrition and health knowledge of the elderly and prevention and treatment of common diseases among the elderly people.

OBJECTIVE: To explore the association between single nucleotide polymorphism (SNPs) of KLK1 gene and cerebral hemorrhage in Changsha Han population. METHODS: We enrolled 273 patients with cerebral hemorrhage and 140 normal people. The SNPs (including rs3212855 and rs5515) of KLK1 gene were analyzed by Snapshot method and direct sequencing. RESULTS: We found rs5515 was not a polymorphic site in Changsha Han population. Genotype and allele frequency in rs3212855 were not different between patients with cerebral hemorrhage and the controls (P>0.05). The blood pressure level was not different between the genotype subgroups. CONCLUSION Neither rs5515 nor rs3212855 is associated with cerebral hemorrhage.
