OBJECTIVETo investigate diagnostic efficacy of transvaginal three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy) in assessing tubal patency with chromolaporoscopy.

METHODSA total of 157 infertile women underwent 3D-HyCoSy to evaluate tubal patency. Among these patients, 39 patients were also examined by chromolaporoscopy. The concordance of the two clinical assessment methods was analyzed by the Kappa coefficient test.

RESULTSAmong the 306 oviducts examined by 3D-HyCoSy, 99 (32.4%) were patent, 126 (41.2%) partially obstructed, and 81 (26.5%) completely obstructed. Diagnostic results with 3D-HyCoSy were not statistically different from those obtained in the 39 women (78 oviducts) who also underwent chromolaporoscopy, and the two methods showed a high concordance (k=0.747, P=0.000). The 3D-HyCoSy procedure had a sensitivity of 84.8% (28/33), a specificity of 96.2% (25/26), and positive and negative predictive values of 93.3% (28/30) and 86.2% (25/29) respectively.

CONCLUSIONTransvaginal 3D-HyCoSy can accurately reveal the spatial path and morphology of the oviduct and is a safe and effective method to evaluate tubal patency.

BACKGROUND:Lithium chloridecan promote the proliferation and osteogenic capacity of bone marrow mesenchymal stem cels in the necrotic region after avascular necrosis of the femoral head, which has become an issue of concern. OBJECTIVE:To compare the advantages and disadvantages of bone marrow stem cel transplantation combined with lithium chloride in the treatment of rabbit femoral head necrosis. METHODS: Passage 2 bone marrow mesenchymal stem cels from 1-week-old New Zealand rabbits were cultured in 0, 5, 10, 20, 40 mmol/L lithium chloride. Forty-eight healthy adult New Zealand rabbits were selected to make femoral head necrosis models in the right femoral head using liquid nitrogen freezing method and then randomized into four groups: model group with no implantation; lithium chloride group given lithium chloride treatment at 3 days after modeling; cel transplantation group given gelatin sponge implantation and bone marrow mesenchymal stem cel suspension injection into the femoral head after modeling; combined group given bone marrow mesenchymal stem cel suspension injection and lithium chloride treatment. Intraperitoneal injection of lithium chloride (45.2 mg/kg) was given daily beginning at the postoperative 3rdday, and the treatment duration was 4 weeks. RESULTS AND CONCLUSION:Lithium chloride at 10 mmol/L had the maximum effect on the proliferation of rabbit bone marrow mesenchymal stem cels, and if the concentration of lithium chloride was > 10 mmol/L, the promotion role of lithium chloride began to decline. After combined treatment, the morphology of the femoral head was restored a little, with increased bone density and thickened trabecular bone; the level of β-catenin in the femoral head was significantly increased in the combined group compared with the cel transplantation group or the lithium chloride group. These findings show that bone marrow stem cel transplantation combined with lithium chloride treatment can promote the recovery from femoral head necrosis by increasing bone mass of the trabecular bone and bone density of the femoral head in the necrotic region.

Objective To investigate the clinical efficacy of nephrotic syndrome in children adjunctively treated by underatured lactalbumin.Methods Thirty-six cases of nephrotic syndrome were studied for about 1 year.The changes in red blood cells of reduced glutathione(GSH) were analyzed in 18 cases of underatured lactalbumin treatment group and 18 cases of control group.The clinical presentations were observed in both groups.Results GSH levels increased in underatured lactalbumin treatment group when compared with control group.The frequency of relapse and upper respiratory tract infection in underatured lactalbumin treatment group were significantly reduced compared with control group.Conclusion Underatured lactalbumin can provide support for the potential use of an antioxidant therapy in these patients.

Objective To study the efficiency of the first time platelet transfusion in patients with blood diseases.Methods Investigate the effect of platelet transfusion in 87 patients with blood diseases.All the patients were transfused 10U platelet (platelet≥2.5×1011 ).Observe CCI after platelet transfusion and analyse the influence factors to the efficiency of the first time platelet transfusion such as the kind of diseases,splenomegaly,fever,age and sex.Results After platelet transfusion,66 patients (75.9 ％) were effective.The efficancy rates were 80.0 ％,78.1％,65.2 ％,82.3 ％ in AA,ITP,AL,MDS (x2=2.88,P＞0.05).In 31 patients with a fever and infaction the efficancy rate was 58.1％,but it was 85.7％ in 56 patients without a fever and infaction (x2=8.3308,P＜0.01).The efficancy rate in 59 patients with non-splenomegaly was 86.4 ％.It was higher than that in 28 patients with splenomegaly which was 53.6％(x2=11.2033,P＜0.01).The efficancy rate was 76.0％ in male patients and it was 75.7 ％ in female patients (x2=- 0.0012,P＞0.05).The efficancy rate was 74.5 ％ in young group (＜60 years old)and 77.8 ％ in old group (≥60 years old)(x2=0.1231,P＞0.05).Conclusion Fever and splenomegaly are the influence factors to the efficiency of the first time platelet transfusion.

OBJECTIVETo compare p27 interfering effect on the proliferation and hematopoietic potential of hematopoietic progenitor cells (HPC) derived from human bone marrow (BM) and umbilical cord blood (UCB), and investigate the related mechanism.

METHODSCD34(+) cells sorted from human BM by flow cytometry and isolated from UCB by a magnetic isolation system were infected with retrovirus-p27 antisense cDNA (p27AS) and cultured with cocktail-cytokines. The cell proliferation capacities were detected by cell growth curve and DNA content analysis, and the hematopoietic potential by colony formation assay. The protein expression of p27 and CDK2 were measured with Western blot. CD34(+) cells infected with retrovirus-p27 sense cDNA (p27SE) and virus-green fluorescence protein (GFP) were used as the control.

RESULTSComparing with groups of GFP and p27SE, p27AS showed to accelerate the expansion of UCB HPC significantly (P < 0.01), the cell number of p27AS, p27SE and GFP increased by 197.3 +/- 47.7-, 12.7 +/- 8.1- and 41.8 +/- 30.6- fold respectively by the end of the 9-day culture, the BM HPC increased by 36.0 +/- 22.3-, 8.7 +/- 6.8- and 14.1 +/- 10.4-fold respectively in the same time as UCB HPC. Cell cycle analysis showed p27AS mainly promoted S phase of BM and UCB HPC. S phase cell percentages of UCB HPC infected with p27AS, p27SE and GFP were (17.0 +/- 4.8)%, (2.0 +/- 0.8)% and (4.1 +/- 1.8)% and that of BM HPC were (8.4 +/- 4.4)%, (1.0 +/- 0.7)% and (3.8 +/- 1.4)% respectively. The yields of colony formation of p27AS for BM and UCB was higher than that for GFP (P < 0.05). Western blot demonstrated the expression of p27 reduced in the p27AS group, while CDK2 increased in the group. The virus infection rate, cell growth rate and colony forming yields of BM HPC was inferior to that of UCB HPC.

CONCLUSIONSp27 gene interfering could promote HPC proliferation, hematopoietic potential and the response to stimulations of UCB HPC is higher than that of BM HPC ex vivo. It seems that cell cycle controlled by p27 was related to CDK2.

Objective To study the relation of matrix metalloproteinase-9 in serum and tumor necrosis fac- tor-?in serum and amniotic fluid in predicting ehorioamnhionitis in patients with premature rupture of membranes (PROM).Methods The levels of MMP-9 in serum and TNF-?in serum and amniotie fluid were measured by ra- dioimmunoassay and ELISA in 67 cases with premature rupture of membranes as study group and 40 cases normal full-termed pregnant women as controls group.Results(1)The levels of TNF-?in amniotie fluid and MMP-9 in serum in study group were significantly higher than those in controls group(P0.05).(2)In study group,the levels of MMP-9 of serum in0.05).Conclusions The levels of TNF-?in amniotic fluid and MMP-9 in serum were valuable clinical indices for identification of chorioamnionitis in patients with PROM.The levels of MMP-9 in serum also could assess the time of rupture of membranes and the degree of ehorioamnionitis.
