Objective To evaluate the feasibility of application of video-laparoscopy to the treatment of acute severe inflammatory pelvic pain in women. Methods Forty-two women patients with severe acute inflammatory pelvic pain were divided randomly into two groups with 21 patients in each group. Conservative therapies were carried out in Group A while laparoscopic operations in Group B. Results Eighteen cases (85.7%) in Group A returned to health, and in the remaining 3 (14.3%), conservative measures failed and thus exploratory operations were performed. Meanwhile all the patients in Group B were treated successfully, with the operative time (42.5?20.6) min, the average blood loss 20ml and the mean hospital stay 7 days. Body temperatures returned to normal on the day of operation and no complications occurred. Conclusions Laparoscopy may be feasibly applied to the treatment of women with severe acute inflammatory pelvic pain, producing results superior to conservative therapies.

Objective·To investigate the correlation between the serum haptoglobin (Hp) level and the metabolic parameters in patients with polycystic ovarian syndrome (PCOS), and explore the distribution of Hp genotype and allele frequency in PCOS patients and their correlations with PCOS. Methods·A total of 106 patients with PCOS and 86 cases of patients with non-hyperandrogenic and regular menstruation (control group) were enrolled. Serum Hp level was measured by enzyme-linked immunosorbent assay (ELISA); Hp genotype and allele frequency were determined by polymerase chain reaction (PCR), respectively. Results·The serum Hp level in PCOS group was significant higher than that in the control group (P=0.000). Correlation analysis reveals that serum Hp level was positively related to body mass index (BMI) (P=0.000) and homeostatic model assessment insulin resistance (HOMA-IR) (P=0.000). Compared with control group, proportion of Hp2-2 genotype (Hp2/Hp2) increased significantly in PCOS group (P=0.006), and the frequency of Hp2 allele was also higher (P=0.002). Conclusion·Serum Hp level was positively related to BMI and HOMA-IR, which maybe associated with the occurrence and development of obesity and insulin resistance. Patients with Hp2-2 genotype might have genetic predisposition to PCOS, and high frequency Hp2 allele was found in them.

Objective To study the effect of expansion ex vivo on the hematopoietic reconstitution of umbilical cord blood (UCB) hematopoietic cells, and to find a probable way of UCB transplantation (UCBT) to be used on adults. Method Three groups of UCB hematopoietic cells were transplanted to lethally irradiated BALB/C mice: fresh cells, a half part of fresh cells and a half part of cells expanded for a week, cells expanded for a week. Results All the three groups of cells could reconstitute hematopoiesis. The cells in the latter two groups could more rapidly accelerate the recovery of early-period hematopoiesis. The death rate of the mice in second group was the lowest among three groups. Conclusion The way transplanted with a half part of fresh UCB hematopoietic cells and a half part of UCB hematopoietic cells ex vivo expanded for a week may be a probable one for adult UBCT.

Objectives To analyze SLC37A4 gene mutations in glycogen storage disease type Ⅰb patients and to investigate the correlation between genotype and phenotype. Methods The clinical data and SLC37A4 gene detection results of 3 cases of glycogen storage disease type Ⅰb were analyzed retrospectively. Results Two males and one female aged 6 years, 9 years, and 16 years respectively were presented with hepatomegaly, fasting hypoglycemia, slactic academia, hyperlipidemia, and granulocytopenia. The analysis of 6 alleles in SLC37A4 gene by direct sequencing of peripheral blood DNA found 4 mutations, including 2 missense mutation (p. Leu23Arg and p.Pro191Leu), one shear mutation (c.870+5G>A), and one deletion mutation (c.1042_1043 del CT). The genotypes of these 3 cases were p.Pro191Leu, p.Pro191Leu;p. Leu23Arg, c.870+5G>A;p.Pro191Leu, p.Leu347ValfsX53 respectively. Conclusions There were 4 mutations detected among these 3 cases of glycogen storage disease type Ⅰb. All of those were known mutations. The most common mutation was p.Pro191Leu. It can not be excluded that P.Gly149Glu homozygous mutation is associated with repeated infections.

Objective:To investigate the effect of NS-398,a selective cyclooxygenase-2(COX-2) inhibitor,on the proliferation and invasion of human colon carcinoma cells in vitro,so as to determine the possibility of COX-2 as a new target for treatment of colon carcinoma.Methods: The expression of COX-2 in colorectal cancer cells(CW-2,COLO-320) was detected by RT-PCR and Western blotting.COLO-320 cell proliferation was measured by MTT after treatment with NS-398.Cell invasion ability was measured using migration and invasion chamber systems.Western blotting assay was used to examine the influence of NS-398 on MMP-2 expression.Results: Our results showed that CW-2,COLO-320 cells expressed COX-2 mRNA and protein.NS-398 inhibited the proliferation of COLO-320 cells in a time-and concentration-dependent manner.Invasion test showed that NS-398 inhibited the migration and invasion of COLO-320 cells.Western blotting revealed that NS-398 inhibited the expression of MMP-2 in COLO-320 cells.Conclusion: The selective COX-2 inhibitor NS-398 can inhibit COLO-320 cell proliferation and invasion,indicating COX-2 may serve as a new target for colon carcinoma treatment.

Objective To construct an eukaryotic expression plasmid PeDNA3.1 (+)/Lpp20 and to detect its expression in HeLa cells, and to observe the humoral and cellular immune responses in C57BL/6 mice induced by the Helicobacter pylori Lpp20 DNA vaccine injected intramuscularly. Methods The Lpp20 gene was amplified by PCR. PCR product was subcloned into the eukaryotic expression vector pcDNA3.1 (+)/ Lpp20, and the recombinant plasmid was transfected into HeLa cells using Liposome. After verifying that the Lpp20 antigen gene could be expressed in HeLa cells. Six weeks old C57BL/6 mice were immunized with pcDNA3.1 (+)/Lpp20 or pcDNA3.1 (+) or PBS buffer intramuscularly at 2-week interval for four times. ELISA was used for the quantitative detection of the specific IgG antibody in the sera of C57BL/6 mice and the cytokine IFN-γ in mice spleen lymphocyte culture medium after stimulating by Lpp20. The proliferation response of spleen cells was detected by MTT assay. The Lpp20 gene in muscle was identified by PCR. Results The significant specific antibody titers were detected by ELISA in DNA vaccine groups and the highest titer was 1:1024 after 6 weeks. The cytnkine IFN-γ in mice inoculated with pcDNA3.1 (+)/Lpp20 was increased and reached (410.36±56.23) pg/ml. A significant difference was tested between the experiment group and the control group[(25.26±10.85)pg/ml] ,P <0.01. The proliferation response of spleen cells of DNA vaccine group(SI: 2.37±0.22) was significantly higher than those of mice injected with pcDNA3.1 (+) (SI:1.53+0.47) ,P<0.01. Lpp20 gene could exist constantly in musculature cells of mice. Conclusion The eukaryotic expression recombinant pcDNA3.1 (+)/Lpp20 was successfully constructed. Strong humoral and cellular im-munity can be induced by DNA vaccine of pcDNA3.1(+)/Lpp20 in C57BL/6 mice, which might be helpful for further investigation concerning the immunoprotection of DNA vaccine.

OBJECTIVETo determine the role of phosphatidylinositol 3-kinase--protein kinase B (PI3K-Akt) signaling pathway in the pro- tective effect of aerobic endurance training on the skeletal muscular mitochondria.

METHODSThirty-six rats were randomly divided into three groups( n = 12): control group, aerobic endurance training group and one-time exhaustive group. After the intervention, the quadriceps femoris muscle sample was obtained to detect the mitochondrial membrane potential( MMP), the activities of succinate dehydrogenase (SDH) and cy- tochrome coxidase (COX), and the protein levels of p-PI3K and p-Akt.

RESULTSCompared with the control group, the levels of mitochondrial membrane potential, the activities of succinate dehydrogenase and cytochrome coxidase, and the protein levels of p-PI3K and p-Akt were all significantly decreased in the one-time exhaustive group (P < 0.05). However, all the above was partially reversed in the endurance training group (P < 0.05), and there was no obvious difference with the control group (P > 0.05).

CONCLUSIONAerobic endurance training plays an important role in the protective effect on the skeletal muscular mitochondria, the mechanism may be related to activation PI3K-Akt signaling pathway.
