Objective To explore the effectiveness and safety of vaginal paravaginal repair(VPVR) plus vaginal bridge repair in the treatment of female pelvic organ prolapse (POP). Methods Sixty-five patients with different defects of pelvic floor underwent VPVR or plus vaginal bridge repair for posterior vaginal wall. Patients were followed up after operation. The cure rate was estimated subjectively and objectively. The patients' quality of life was evaluated by the pelvic floor distress inventory short form 20 (PFDI-20). Results All 65 cases were treated by vaginal hysterectomy and anterior vaginal repair, in which there were 33 cases underwent VPVR while 32 cases underwent VPVR plus middle area repair. Forty concomitant procedures for vaginal bridge repair were also performed. The average operative time was (110.00±20.12) min and blood loss was (119.52±45.33) ml. The symptom of stress urinary incontinence of 25 cases significantly released after operation. Four incision recovery delayed and there were no other complicatious occurred. Patients were followed up for 6-29 months,the objective cure rate was 100.00% (65/65) and subjective cure rate was 92.31%(60/65), and 58 cases (89.23%)improved significantly with the quality of life comparing with that of pre-operation by completing PFDI-20 (P<0.01). Conclusions It is an effective and safe procedure for VPVR plus vaginal bridge repair to correct median to severe anterior vaginal prolapse and posterior vaginal wall prolapse. More clinical trials are needed to evaluate their long-term outcome.

Objective To investigate the endurance or resistance of different bacteriophages to bubbling stress in different sampling solutions,to select the optimum sampling solution from three different ones and to select relatively stress-resistant bacteriophages from five different ones.Methods AGI-10(all glass impinger)was used as the representative for all the impingers that would bubble during operation to fulfill the bubbling experiment.Three different sampling solutions used,such as distilled water(DW),phosphatic buffer solution(PBS),and suspension medium(SM),were divided into two groups by adding olive oil(50 μl) or otherwise(0 μl).The impingers were operated 30 min at a flow rate of 7.0 L/min.The titers of bacteriophages and the volume of final sampling solutions were determined before the corrected survival probability was used to evaluate the stress resistance of several different bacteriophages.Results It was found that the survival probability of the same bacteriophage bubbling with different sampling solutions was different except for bacteriophage F2.The use of SM as the collection fluid was related to a high survival probability which remained unchanged between 50 μl and 0 μl olive oil.The corrected survival probability was 79%,77%,86%,50% and 71% for phage SM701,SM702,PhiX174,EcP1 and F2 respectively after 60 minutes of impingement at a flow rate of 7.0 L/min.Conclusion The endurance or resistance of different kinds of bacteriophages in the same sampling solution is different.SM might be an optimum sampling solution for phages.Bacteriophage SM701,SM702 and PhiX174 are more resistant to bubbling stress than EcP1 and F2.

OBJECTIVETo show the space structures of Mingmen (GV 4) area and its adjacent tissues.
METHODSA frozen female corpse was cut into about 0.5 mm thick sections with a high-speed steel plane machine and photographed with digital and optical camera. Two 2-D transverse phase picture data sets were obtained and then were sequenced, matched, modified and divided. The 3-D reconstruction software was used to reconstruct the outline form of the lumbar part containing Mingmen (GV 4) to attain transverse phase picture data sets (3 022 sheets, 0.57 mm in thickness). The sagittal, coronal and different oblique plane were cut and the tissue structures in these pictures were analyzed. Thus, the reconstruction data sets were obtained.
CONCLUSIONAfter the structures of Mingmen (GV 4) were reconstructed with computer, the form of Mingmen (GV 4) can be dynamically observed from any angle and the space construction law of gross form of Mingmen (GV 4) can be proved.

To optimize the culture environment and protocol of hematopoietic cells' expansion, avoiding the fluctuation caused by medium changing in stirred culture and concentration gradient in static culture, the hematopoietic cells from cord blood (CB) were cultured in a stirred bioreactor connected with a cell retention system, which is a gravity sedimentation settler designed for hematopoietic cell. Total cells expanded 11.5 and 18.6 fold respectively in the twice perfusion stirred cultures, in which CFU-Mix was expanded 23.2 and 20.4 fold, CFU-GM 13.9 fold and 21.5 fold, BFU-E 8.0 fold and 6.9 fold, CD34+ cells 17.1 fold and 15.4 fold. After 12-day culture, it was obtained that 1082 x 10(6) total cells, 6.31 x 10(6) CFU-GM, 6.2 x 10(6) CFU-Mix and 23 x 10(6) CD34+ cells from 267 x 10(6) CB mononuclear cells (MNC) in the first culture, and 1080 x 10(6) total cells, 4.65 x 10(6) CFU-GM, 11.0 x 10(6) CFU-Mix, and 25.0 x 10(6) CD34+ cells from 180 x 10(6) CB MNC. These two cultures met to the clinical scale. Due to the optimized dissolved oxygen (DO) and stable culture environment, the rate of stem/progenitor cells to total cells in the perfusion culture was higher than that in T-flask cell-retention feeding culture. But the cell growth was inhibited in the later phase of perfusion culture, when the cell density is high. The inhibition should be attribute to the high cell density itself. The perfusion culture environment in bioreactor with optimal DO and pH controlling is more favorable for stem/progenitor cells' maintenance and expansion, and the expanded cells' number has reached a clinical scale. But the high cell density in the later phase of perfusion culture caused inhibition to mature hematopoietic cell's growth.

OBJECTIVETo explore the changes of substance P in cornu dorsal medullae spinalis effected by activation of astrocytes in rats with pain from chronic prostatitis.
METHODSSixty SD rats were randomized into three groups: the control group (n=20), the chronic prostatitis pain model group (n=20) and the interference group (n=20). The model was induced by injection of complete Freund adjuvant and 3% carrageenan into the prostate. Propentofylline was given with PE-10 in the spinal cord of the rat models. The activation of astrocytes and the distribution of substance P in the spinal cord were detected with immunofluorescence and the changes of substance P observed by radioimmunoassay.
RESULTSThe activation of astrocytes was significantly increased in the models compared with controls, but significantly reduced in interfered group in comparison with the pain model group (P < 0.01), and such was the case with substance P (P <0.01).
CONCLUSIONThe activation of astrocytes was one important reason for the changes of substance P excreted from cornu dorsal medullae spinalis in the chronic prostatitis rats.

The prenatal ethanol exposure induced the alterations of dendritic spine and synapse in visual cortex and their long-term effect would be investigated in mice from P0 to P30. Pregnant mice were intubated ethanol daily from E5 through the pup's birth to establish mode of prenatal alcohol abuse. The dendritic spines of pyramidal cells in visual cortex of pups were labeled with DiI diolistic assay, and the synaptic ultrastructure was observed under transmission electron microscope. Prenatal alcohol exposure was associated with a significant decrease in the number of dendritic spines of pyramidal neurons in the visual cortex and an increase in their mean length; ultrastructural changes were also observed, with decreased numbers of synaptic vesicles, narrowing of the synaptic cleft and thickening of the postsynaptic density compared to controls. Prenatal alcohol exposure is associated with long-term changes in dendritic spines and synaptic ultrastructure. The changes were dose-dependent with long term effect even at postnatal 30.

OBJECTIVETo explore the relationship between expression thange of P-selectin after brain injury and secondary brain damage.
METHODSSixty SD rats were randomized into 3 equal groups, namely the control group, mild injury group and severe injury group and animal models of brain injury were established in SD rats according to the method of Feeney. P-selectin expression in the brain tissues were determined at 6 h and l, 3, and 7 days following brain injury (n=5 for each time point). Imaging analysis was performed using computerized imaging technique.
RESULTSP-selectin expression and neutrophil infiltration in the brain tissues increased significantly 6 h after brain injury (P<0.05), reaching the peak level at postoperative 24 h and then gradually decreased.
CONCLUSIONP-selectin expression and neutrophil infiltration increase significantly following brain injury, and the time course and distribution of P-selectin expression are consistent with the secondary damage of the brain, strongly suggesting the involvement of P-selectin upregulation in the secondary insult after brain injury.

We report the clinical characteristics, treatments and outcomes of 4 rare cases of mixed amanita fuliginea and amanita rimosa poisoning with rhabdomyolysis, and review the research progress in the intoxication mechanism and treatment. The latent time of amanita poisoning, defined as the period from the ingestion of poisonous mushroom to the onset of gastrointestinal symptoms, was about 8 days, and the severity of poisoning was associated with the amount of mushroom ingested. All the 4 patients developed multiple organ dysfunctions within 3 to 4 days after mushroom ingestion, predominantly in the liver, kidney and central nervous system accompanied with acute gastrointestinal injury and rhabdomyolysis. The treatment measures included persistent hemofiltration and intermittent hemoperfusion once daily for 5-7 days, and plasma exchange was administered in 2 cases for 1 or 2 times. High-dose vitamin C, glucose and corticosteroid were also given to the patients. After the treatments, two patients were cured and the other two died due to an excess intake of poisonous mushroom and lack of early preemptive therapies. Early emetic, gastric lavage, catharsis, fluid infusion and diuresis are critical to interrupt the enterohepatic circulation of amanita phalloides toxins and prevent the development of multiple organ dysfunction. Enhanced hemofiltration and sequential plasma therapy might effectively eliminate toxin from the blood to protect against further organ damages.
