AIM: To discuss the establishment of immediate diabetic keratopathy animal model of C57BL/6 mouse induced by ahigh-fat and high-glucose diet.
METHODS: Diabetes mellitus was induced by a high-fat and high-glucose diet in C57BL/6 mouse. 1% rose bengal was stained on the cornea to examine the integrality of the corneal epithelium at 2 ~ 12mo after completion of the model. Corneal epithelial wound healing was observed using a vivo epithelial debridement model which was dyed by sodium fluorescein. Corneal morphology histology was examined by pathological methods.
RESULTS: The high-fat and high-glucose diet C57BL/6 mouse in 2mo had showed general symptoms of diabetes: polydipsia, polyphagia, polyuria, weight loss etc. The model had a steady-state high glucose (≥18mmol/L), also the weight was lower compared with normal control mouse. 1% rose bengal corneal staining had dot coloring at 2mo after completion of the model, the stained area and extent were gradually increased with the extension of the duration of diabetes, almost all the cornea was stained at 12mo after completion of the
model. With the passage of time into a mold, the cornea epithelial healing time become longer: 2mo was about 40h;3mo was about 120h; 4, 6, 12mo was about 144h;the coloboma were gradually increased at 12mo after completion of the model, then the area was reduced gradually until complete healing, the time was 96~120h, showed repeating phenomenon.
CONCLUSION: The mouse were induced by high-fat and high-glucose diet can be used as animal models of diabetic keratopathy: the damage of epithelium for corneal and delay healing on epithelium and other symptoms.

Objective To analyze behavior of having multiple sexual partners among outside school adolescents and the impact factors in one county.Method Participatory method was adopted in the survey,trainees of an occupational training center were trained to investigate their peers with anonymous questionnaires.Results The subjects who had more than 3 sexual partners accounted for 38.3%,and the factors related to multiple sexual partners were complicated.The most im- portant protective factor was to raise level of HIV/AIDS related knowledge (OR=0.85);the key risk factors were: promiscuous behaviors (OR=4.91) and prostitution(OR=3.37) among their friends.Conclusion For reducing behav- ior of having multiple sexual partners among outside school adolescents,it is essential to promote HIV/AIDS related health education and to enhance their ability to respond to pressures from their bad peers.

Objective To study the short-term outcome of the uterine fibroids treated with ultrasound-guided percutaneous microwave ablation therapy (PMAT) by magnetic resonance imaging (MRI). Methods PMAT was performed in 46 symptomatic patients with a total of 49 uterine fibroids. Pre-and post-contrast MRI was scanned at 3 days before treatment and 3 days after treatment to assess image changes of both fibroids and surrounding tissues. The fibroids were divided into group A (low signal), B (iso-signal), C (high signal) by the signal intensity on T2WI. According to the volume changes of fibroids and uterine, ablation rate and the reduction rate of the fibroids after treatment were calculated. Results There were 28, 17 and 4 fibroids in the group A, B and C respectively. Before the treatment the volume of the fibroids showed no statistical difference between the group A, B and C (P>0.05). Fibroids and uterine showed shrinkage after the treatment in the group A and B (t=5.644, 5.998, 6.725 and 4.678, all P<0.001). The fibroids ablation rate showed no statistical difference between the groups (F=0.852, P>0.05). Fibroids and uterine showed shrinkage after the treatment in the group C, but there was no obvious statistical difference. Conclusion The outcome of PAMT is good for the fibroids with different signal intensity on T2WI. But the fibroids with high signal intensity are not as sensitive as those with low or iso intensity to achieve the same ablation level.

OBJECTIVE: To assess the effect of CPAP therapy on sleep quality and quality of life in patients with moderate or severe OSAHS. METHOD: Seventy-two patients diagnosed as OSAHS by polysomnography (PSG) were assigned to receive CPAP therapy for 3 months. At baseline and three months after treatment patients underwent polysomnography (PSG). Analyze the results of PSG, sleep quality, excessive daytime sleepiness, quality of life and the general well-being. RESULT: The lowest average oxygen saturation and the average blood oxygen saturation improved significantly after CPAP therapy, and the longest sleep apnea time and AHI decreased obviously (P < 0.01). Except body pain, the other seven dimensions of SF-36 improved obviously (P < 0.01); ESS, PSQI and GWB also improved (P < 0.05). CONCLUSION For patients with moderate or severe OSAHS, CPAP therapy can obviously improve the sleep quality, excessive daytime sleepiness, improve patients' life quality and the general well-being.

Objective To explore the therapeutic effect of combining continuous venovenous hemofiltration (CVVH) with hemoperfusion (HP) on patients with septic shock.Methods A prospective study was conducted. Thirty-two patients with septic shock admitted to Changshu No.1 People's Hospital were enrolled, and they were divided into two groups according to random digits table. The observation group (17 cases) was given HP before CVVH, in the control group (15 cases), only CVVH treatment was carried out, and lasting for 5 days in both groups. The changes of pulse oxygen saturation (SpO2), central venous pressure (CVP), systemic vascular resistance index (SVRI), cardiac index (CI), extra-vascular lung water index (EVLWI) were observed before treatment and 5 days after treatment.Results Compared with those before treatment, the levels of SpO2, CVP, SVRI, CI were obviously elevated, and EVLWI was markedly decreased after treatment in two groups. Compared with those of control group, the degrees of improvement of above indicators in observation group were more prominent [SpO2: 0.966±0.035 vs. 0.939±0.036, CVP (mmHg, 1 mmHg = 0.133 kPa): 8.5±3.2 vs. 8.1±4.2, SVRI (kPa·s·L-1·m-2): 1 497.35±157.08 vs. 1 343.60±144.48, CI (mL·s-1·m-2): 120.36±15.34 vs. 106.69±12.33, EVLWI (mL/kg): 6.84±0.73 vs. 7.65±0.70, allP < 0.05].Conclusion Combing HP with CVVH for treatment of patients with septic shock can improve their prognosis more obviously than using CVVH alone.

Objective:To explore the clinical efficacy of sinew-regulating and bone-setting manipulation combined with functional exercise to treat mild to moderate rotator cuff injury (RCI).Methods:Forty patients with mild to moderate RCI were randomly divided into a treatment group and a control group,with 20 cases in each group.The treatment group was given sinew-regulating and bone-setting manipulation combined with functional exercise,and the control group was given the same manipulation as the treatment group.The therapeutic effect on the functional improvement was assessed after treatment according to pain threshold,shoulder range of motion (ROM) including flexion,abduction,internal rotation and external rotation,and the University of California at Los Angeles (UCLA) shoulder rating score.Results:Compared with the same group before treatment,the pain threshold,shoulder flexion,abduction,internal and external rotations increased after the treatment in the two groups (all P＜0.05).The UCLA shoulder rating score increased (both P＜0.05).The improvement in the treatment group is significantly better than that in the control group with a statistical significance (P＜0.05).The total effective rate was 95.0％ in the treatment group,was higher than 65.0％ in the control group (P＜0.05).Conclusion:The sinew-regulating and bone-setting manipulation combined with functional exercise relieve the pain of patients with mild to moderate RCI,increase the motion of shoulder joints,and improve the quality of life of patients.The curative effect is better than the treatment of simple sinew-regulating and bone-setting manipulation.

OBJECTIVETo investigate the effects of advanced glycosylation end products (AGEs) modified bovine serum albumin (AGE-BSA) on the expression of reactive oxygen species (ROS) and monocyte chemoattractant protein-1 (MCP-1) in human renal mesangial cells (HRMCs).

METHODSHRMCs were cultured in vitro with medium containing different doses of AGE-BSA or BSA (50,100, 200, 400 mg/L) for 48 hours, or with AGE-BSA (200 mg/L) for different times (12, 24, 48, 72 h). Immunocytochemistry assay was used to estimate the protein level of RAGE. The ROS in cells were measured by flow cytometry and the mRNA expression of MCP-1 were analyzed by semi-quantiative reverse transcription-polymerase chain reaction (RT-PCR) after treatment with AGE-BSA or BSA.

RESULTSThe protein level of RAGE was upregulated in the HRMCs with AGE-BSA. The expression of ROS and MCP-1 significantly enhanced by incubation of AGE-BSA in a time- and dose-dependent manner. The effects of AGE-BSA-induced up-regulation of ROS and MCP-1 level was significantly blocked by neutralizing antibodies to RAGE, while the expression of ROS and MCP-1 stood nearly unchanged after cultured with huamn IgG.

CONCLUSIONThe expression of ROS and MCP-1 in HRMCs is induced by AGE-BSA through RAGE, which may have potential effects in the pathgenic mechanism of diabetic nephropathy.
