OBJECTIVETo observe the effects of Stragalus membranaceus injection on nitric oxide and endothelin levels of intestinal mucosa in reperfusion injury after hemorrhage shock.

METHOD32 SD rats were randomly divided into four groups: normal group, model group, low dosage group, (treated with Astragalus membranaceus 10 g x kg(-1)); high dosage group (treated with Astragalus membranaceus 20 g x kg(-1)). Models of hemorrhagic shock for 60 minutes and reperfusion for 90 minutes were created. The animals were administrated 3 mL therapeutic solution before reperfusion. At the end of study, intestinal pathology was observed, and the concentration of lactic acid (LD), nitric oxide (NO), endothelin (ET) of intestinal mucosa were detected.

RESULTThe intestinal pathology showed that intestinal mucosa epithelial cells damage in model group was severe, in low dosage group was medium, in high dosage group was slight, and no obvious damage was found in normal group. The concentration of LD and NO of small intestine mucous membrane in model group and low dosage group were significantly higher than those in high dosage group and normal group (P < 0.05), but there were no significant differences between high dosage group and normal group (P > 0.05). The concentration of ET of small intestine mucous membrane in model group was the highest of the four groups (P < 0.05). The concentration of ET in low dosage group was significantly higher than that in high dosage group and normal group (P < 0.05), but there were no significant differences between high dosage group and normal group (P > 0.05).

CONCLUSIONStragalus membranaceus injection can reduce small intestine mucous damage by protecting endothelium function in injury after hemorrhage shock-reperfusion.

Objective To explore the relation between the positive rates of autoantibodies against β1 adrenergic receptor(β1-receptor) and (M2-receptor) with urinary albumin excretion rate (UAER) in type 2 diabetes patients with refractory hypertension.Methods Autoantibodies against β1-and M2-receptor as well as autoantibodies were determined in type 2 diabetes patients with(n=136)or without(n=11 1) refractory hypertension,hypertensive patients without renal failure (n=60) and healthy contrel snbjects (n=40.control) by ELISA.Resuits The positive rates of the autoantibodies against β1.receptors (44.9%) and M2-receptor(37.5%)in patients with type 2 diabetes with refractory hypertension were significantly higher than those in patients with type 2 diabetes without refractory hypertension (27.9% and 24.3%,respectively.all P<0.05),in patients with hypertension without renal failure(11.7%and 15.0%.all P<0.01) and in healthy controls(8.3%and 7.5%,all P<0.01).In type 2 diabetes patients with refractory hypertension and renal failure (UAER≥200 μg/min),the positive rates of the autoantibodies against β1-receptor(87.1%,27/31)and against M2-receptor (67.7%,21/31) were significantly higher than those in type 2 diabetes patients with refractory hypertension but without renal failure (UAER 20-199 μg/min,46.7%,28/60 and 41.7%,25/60.respectively.all P<0.05).Conclusion The serum β1-and M2-receptor autoantibodies are positively associated with the UAER level and suggest that these autoantibodies against β1 and M2-receptor may play important roles in the pathogenesis of the type 2 diabetes with refractory hypertension.

Objective To observe effects of Heyutai Fuzhu Jiangtang Tablets combined with metformin in insulin resistance (IR); To discuss its mechanism of action. Methods 6–7 week old male ZDF (fa/fa) rats were randomly divided into model group,metformin group,Heyutai Fuzhu Jiangtang Tablets group(Jiangtang Tablets group),and metformin combined with Heyutai Fuzhu Jiangtang Tablets group.ZDF(fa/+)rats were chosen as normal group.Each medication group was given relevant medicine for gavage for 6 weeks. Body weight, FBG, TG, TC, FFA, FINS, HOMA-IR, OGTT and HE staining were tested. HE staining was used to observe the pathological changes of skeletal muscle. RT-PCR and Western blot were used to detect skeletal muscle corresponding gene and protein expression. Results Compared with Jiangtang Tablets group and metformin group, TC, FFA, FBG, and HOMA-IR in metformin combined with Heyutai Fuzhu Jiangtang Tablets group decreased significantly (P<0.05, P<0.01). Blood glucose level and AUC significantly decreased at each time point in OGTT. HE staining of skeletal muscle fibers arranged in order; nucleus increased and internal movement was not significant, without obvious infiltration of inflammatory cells. Expressions of skeletal muscle InsR, Akt, and Glut4 mRNA expression increased (P<0.05, P<0.01). Expressions of skeletal muscle p-InsR, p-Akt, and Glut4 protein expression increased (P<0.05, P<0.01). Conclusion Heyutai Fuzhu Jiangtang Tablets combined with metformin can improve IR in type 2 diabetic rats, and the effect is better than single-application.

OBJECTIVE: To explore the feasibility of improving the sensitivity of DNA detection by increasing the PCR cycle index and decreasing the volume of amplifying system. METHODS: The DNA of semen were collected from 10 healthy irrelevant volunteers, and were quantified to 50, 40, 30, 25, 20, 15, 10 pg/microL, separately. All samples were then amplified in 10, 5, 3 microL volume and at 28, 30, 32, 34, 36 cycles, respectively. 3130 genetic analyzer was used to detect 15 autosomal STR loci. RESULTS: Under the situation of 28 cycles and 3 microL volume, samples which achieved > 40 pg/microL could be correctly typed. Under the situation of 10, 5, 3 microL volume, samples which achieved > 20 pg/microL could be correctly typed at 34 cycles. When increasing the index to 36 cycles, they could not be correctly typed because of the non-specific band. CONCLUSION DNA detecting sensitivity can be improved to a certain extent by increasing the cycle index and decreasing the volume of amplifying system.

The aim was to verify the effectiveness of slide platelet aggregation test (SPAT) to monitor the inhibition effect of anti-platelet drugs. A group of eight healthy volunteers was examined for SPAT value and T(50) (time necessary for reaching 50% of total aggregation) induced by ADP, arachidonic acid (AA) and cationic propyl gallate (c-PG) respectively before and after administration of ASA in dose of 100 mg/day for 3 days. The group of 41 inpatients at the Department of Cardiovascular Disease treated with anti-platelet drugs and the group of 327 healthy blood donors were also examined for SPAT. The SPAT value of healthy volunteer samples stored at room temperature were measured hourly for four hours. The results showed that: (1) no significant difference was detected between the T(50) before and after ASA administration in health volunteer group when ADP was used as inducer, but a significant difference was detected in this group when AA or c-PG was used as inducer. There was significant linear correlation between SPAT value and T(50) induced by c-PG in health volunteer group before and after administration of ASA (r = 0.998, P = 0.000); (2) there was no significant difference between the SPAT value of health volunteer group before administration of ASA and the SPAT value of health blood donors group (P = 0.853), but there was a significant difference between the SPAT values before and after administration of ASA in health volunteer group (P = 0.000). There was significant difference when the SPAT value of the inpatients treated with anti-platelet drugs was compared with that of healthy blood donor group and with that of health volunteer group before and after administration of ASA (P = 0.000). The cut-off value of SPAT in health blood donor group was 44.6 +/- 11.7 seconds, reference value was from 21.1 seconds to 68.0 seconds; (3) there was no significant difference between SPAT values when platelets samples stored at room temperature for 1, 2, 3, 4 hours (P = 0.815). In conclusion, SPAT can rapidly monitor the inhibition effect of anti-platelet drugs and SPAT may have the similar clinic value with T(50) induced by c-PG.

OBJECTIVETo explore clinical and chest X-ray features of SARS in children to facilitate correct diagnosis.

METHODSClinical manifestations and chest X-ray findings in five children suffering from SARS admitted for treatment in the hospital between February and May, 2003 in Shenzhen area were analyzed. The diagnosis was confirmed by epidemiological, clinical, laboratory and radiological examinations. Among the 5 cases, 1 was a boy and the others were girls at the age of 4 to 13 years.

RESULTSOf the 5 SARS children, 3 presented a history of close contact with SARS patients. Fever was the initiative symptom, 4 had a body temperature of over 38 degrees C with the highest being 40 degrees C; fever sustained from 4 to 7 days with an average of 5.6 days. All the 5 cases developed nonproductive cough; on auscultation, both moist and dry rales could be heard in 3 out of the 5 cases. Mean total white count of peripheral blood was (2.96 - 6.9) x 10(9)/L, and was < 5.0 x 10(9)/L in 4 cases. SARS associated coronavirus specific RNA fragment was found positive by RT-PCR in 1 case; 1 case was positive for both IgM and IgG antibodies to the virus; 1 case was positive for only IgM antibody and another 2 cases were positive for only IgG antibody. IgG and IgM antibodies to Mycoplasma pneumoniae and Chlamydia pneumoniae as well as blood culture for bacteria were all negative. Findings on chest X-ray examination: 4 cases showed presence of patchy or macular opacities with cord-like shadows in unilateral lung plates while 1 case each showed ground-glass-like opacity and migratory changes; 1 case showed interstitial changes in the lungs in the form of irregular reticular lattice and cord-like shadows. Two cases received CT scanning and macular-patchy or spotty shadows were seen all over the lung. The shortest time for absorption of foci in the lungs was 7 days while the longest was 33 days with a mean of 15 +/- 6 days. None of the cases had any signs of fibrosis in the lungs. All the 5 cases were completely cured and discharged 7 to 40 days (mean 18 +/- 11 days) after admission.

CONCLUSIONCompared with adult cases with SARS, children with SARS had milder symptoms and signs. Presence of unilateral patchy shadow in lungs represented the main chest X-ray findings.

Objective: To investigate the effects of glucose-6-phosphatase catalytic subunit (G6PC) recombinant adenovirus on proliferation and cell cycle regulation of liver cancer cells. Methods: Recombinant adenovirus AdG6PC was constructed. Huh7 cells and SK-Hep1 cells were set as Mock, AdGFP and AdG6PC group. Cell proliferation and clone formation assay were used to observe the proliferation of liver cancer cells. Transwell and scratch assay were used to observe the invasion and migration of liver cancer cells. Cell cycle flow cytometry assay was used to analyze the effect of G6PC overexpression on the proliferation cycle of liver cancer cells. Western blot was used to detect the effect of G6PC overexpression on the cell-cycle protein expression in liver cancer cells. Results: The recombinant adenovirus AdG6PC was successfully constructed. Huh7 and SK-Hep1 cells proliferation assay showed that the number of proliferating cells in the AdG6PC group was significantly lower than the other two groups (P < 0.05). Clone formation assay showed that the number of clones was significantly lower in AdG6PC than the other two groups (P < 0.05), suggesting that G6PC overexpression could significantly inhibit the proliferation of liver cancer cells. Transwell assay showed that the number of cell migration was significantly lower in AdG6PC than the other two groups (P < 0.05). Scratch repair rate was significantly lower in AdG6PC than the other two groups (P < 0.05), suggesting that G6PC overexpression can significantly inhibit the invasion and migration of liver cancer cells. Cell cycle flow cytometry showed that G6PC overexpression had significantly inhibited the Huh7 cells G(1)/S phase transition. Western blot result showed that G6PC overexpression had down-regulated the proliferation in cell-cycle related proteins expression. Conclusion: G6PC inhibits the proliferation, cell-cycle related expression, and migration of liver cancer cells by inhibiting the G(1)/S phase transition.

Background/Aims: Depression and anxiety are associated with poorer outcomes in patients with hepatocellular carcinoma (HCC). However, the prevalence of depression and anxiety in HCC are unclear. We aimed to establish the prevalence of depression and anxiety in patients with HCC. Methods: MEDLINE and Embase were searched and original articles reporting prevalence of anxiety or depression in patients with HCC were included. A generalized linear mixed model with Clopper-Pearson intervals was used to obtain the pooled prevalence of depression and anxiety in patients with HCC. Risk factors were analyzed via a fractional-logistic regression model. Results: Seventeen articles involving 64,247 patients with HCC were included. The pooled prevalence of depression and anxiety in patients with HCC was 24.04% (95% confidence interval [CI], 13.99–38.11%) and 22.20% (95% CI, 10.07–42.09%) respectively. Subgroup analysis determined that the prevalence of depression was lowest in studies where depression was diagnosed via clinician-administered scales (16.07%;95% CI, 4.42–44.20%) and highest in self-reported scales (30.03%; 95% CI, 17.19–47.01%). Depression in patients with HCC was lowest in the Americas (16.44%; 95% CI, 6.37–36.27%) and highest in South-East Asia (66.67%; 95% CI, 56.68–75.35%). Alcohol consumption, cirrhosis, and college education significantly increased risk of depression in patients with HCC. Conclusions One in four patients with HCC have depression, while one in five have anxiety. Further studies are required to validate these findings, as seen from the wide CIs in certain subgroup analyses. Screening strategies for depression and anxiety should also be developed for patients with HCC.

Objective To investigate the relationship between single nucleotide polymorphisms(SNPs)in the eNOS gene and genetic susceptibility to systemic lupus erythematosus(SLE)in Hainan.Methods Blood samples were collected from SLE patients(SLE group,n=214)and healthy controls(control group,n=214)from January 2020 to December 2022 at the First Affiliated Hospital of Hainan Medical College and Hainan Provincial People's Hospital.The bases of eNOS gene rs3918188,rs1799983 and rs1007311 loci in each group were detected by SNaPshot sequencing technology.Logistic regression was used to analyze the correlation between genotypes,alleles and gene models(dominant model,recessive model,and overdominant model)of the above 3 target loci of the eNOS gene and genetic susceptibility to SLE.Haplotype analysis was conducted using HaploView 4.2 software to investigate the relationship between haploid and genetic susceptibility to SLE at each site.Results The results of logistic regression analysis revealed that the CC genotype and the C allele at rs3918188 locus were risk factors for genetic susceptibility to SLE(CC vs.AA:OR=2.449,P<0.05;C vs.A:OR=2.133,P<0.001).In recessive model at rs3918188 locus,CC genotype carriers had an increased risk of SLE development compared with AA+AC genotype carriers(OR=2.774,P<0.001).In contrast,in overdominant model at this locus,AC genotype carriers had a decreased risk of SLE occurrence compared with AA+CC genotype carriers(OR=0.385,P<0.001).In addition,polymorphisms of rs1799983 and rs1007311 were not associated with susceptibility to SLE in genotype,allele type and the 3 genetic models(P>0.05).Haplotype analysis revealed a strong linkage disequilibrium between the rs1007311 and rs1799983 loci of the eNOS gene,but no significant correlation was found between haplotype and genetic susceptibility to SLE(P>0.05).Conclusion The CC genotype and C allele at rs3918188 locus of eNOS gene may be risk factors for SLE in Hainan,while the risk of SLE occurrence is reduced in carriers of AC genotype under the overdominant model.
