OBJECTIVETo explore the therapeutic efficacy of unilateral multiple channels approach in percutaneous vertebroplasty (PVP) for osteoporotic vertebral fractures.

METHODSA retrospective review (from March 2003 to October 2012) was conducted on 685 consecutive patients, a total of 885 vertebrae were involved. Eighty-two cases (99 vertebrae) with bone cement leakage when less than 0.3 ml bone cement was injected to fill the fracture were given PVP procedure by unilateral multiple channels approach. 38 cases were male (45 vertebrae) and 44 cases were female (54 vertebrae). The average age was 75.4 years old (from 69 to 92). The operation time, amount of injected bone cement and complications were recorded. Rate of excellent and good outcomes was studied by measuring the cement distribution on the X-ray film. The visual analogue scale (VAS) score and Oswestry disability index (ODI) system were used to evaluate the pain relief and improvement of daily activity function respectively at preoperation and 1 hour, 1 month, 3 months and 6 months after operation.

RESULTSAll these ninety-nine vertebrae were treated in 82 cases with PVP of unilateral multiple channels approach. The average operation time was 33 minutes. The rate of excellent and good outcomes of cement distribution was 98.8%. The VAS score was (8.40 +/- 0.73) before surgery,and (2.50 +/- 0.43), (2.00 +/- 0.33), (1.80 +/- 0.28), (2.10 +/- 0.17) at 1 hour, 1 month,3 months and 6 months respectively after operation. ODI was (40.94 +/- 2.72) before surgery, (9.64 +/- 2.60) at 1 month after surgery, (8.52 +/- 2.30) at 3 months after surgery and (7.77 +/- 2.15) at the final follow-up. The differences of the VAS and ODI between pre-operation and post-operation had statistical significance (P<0.01). No spine or nerve injuries occurred intraoperatively.

CONCLUSIONThe unilateral multiple channels approach in percutaneous vertebroplasty can obviously relieve the pain and effectively improve the functional activity, provide a satisfied cement distribution in vertebral body with cement leakage after a small amount infusion.

OBJECTIVETo investigate the clinical value of Paroxetine combined with mid-frequency electrical pulse acupoint stimulation (EPAS) in the treatment of premature ejaculation (PE).

METHODSTotally 69 PE patients were equally assigned to receive oral Paroxetine 20 mg/d, mid-frequency EPAS, or oral Paroxetine 10 mg/d combined with mid-frequency EPAS (P + EPAS) , all for 8 weeks. We obtained the intravaginal ejaculation latency time (IELT) and Chinese Index of Premature Ejaculation (CIPE-5) scores of the patients before and after treatment, and compared adverse reactions among the three groups of patients.

RESULTSOne patient of the Paroxetine group gave up treatment because of abdominal pain and nausea. Compared with the baseline, the patients in the Paroxetine, EPAS, and P + EPAS groups all showed markedly increased IELT ([0.92 ± 0.11] vs [4.07 ± 0.11] min, P < 0.01; [0.92 ± 0.12] VS [2.78 ± 0.17] min P < 0.05; [0.91 ± 0.09] vs [5.31 ± 0.13], P < 0.01) and decreased CIPE-5 scores (12.5 ± 3.0 vs 22.0 ± 2.1, P < 0.01; 12.8 ± 2.9 vs 19.5 ± 1.9, P > 0.05; 13.1 ± 2.8 vs 25.2 ± 2.1, P 0.01), with statistically significant differences between the P + EPAS group and the other two (P < 0.05). The total effectiveness rate was 95.7% in the P + EPAS group, remarkably higher than in the Paroxetine (72.7%, P < 0.05) and the EPAS group (47.8, P < 0.01).

CONCLUSIONOral Paroxetine combined with mid-frequency EPAS has a higher safety and efficacy than either Paroxetine or EPAS alone in the treatment of PE.

OBJECTIVE: To explore the therapeutic efficacy of manual reduction combined with percutaneous vertebroplasty in treating osteoporotic vertebral compression fractures(OVCFs) with intravertebral clefts. METHODS: The clinical data of 94 patients with osteoporotic vertebral compression fractures with intravertebral clefts treated from January 2014 to January 2017 were retrospectively analyzed. The patients were divided into group A and group B according to different operative methods. In group A, 45 patients were treated with unilateral approach PVP, including 17 males and 28 females, aged (75.35±11.82) years old, with a bone density T-value of (-4.28±0.65) g/cm³; in group B, 49 patients treated with manual reduction combined with unilateral approach PVP, including 19 males and 30 females, aged (76.79±9.64) years old, with a bone density T-value of (-4.33±0.72) g/cm³. The operation time, bone cement injection volume and postoperative complications of two groups were recorded. The VAS and ODI scores of two groups were analyzed respectively at 1, 12, 18 months after operation. Vertebral height and kyphosis Cobb angle of two groups were compared immediately after surgery and 12, 18 months after operation. The distribution of bone cement in the vertebral body was observed and its distribution excellent rate was calculated. RESULTS: There was no significant difference in operation time between two groups. The amount of bone cement injection was(8.42±1.24) ml in group A and(9.19±1.09) ml in group B, and the difference between two groups was statistically significant(<0.05). No spinal nerve root injury during operation and no complications including pulmonary embolism, bone cement toxicity and infection were found in two groups. There were 5 cases of bone cement leakage in group A and 4 cases in group B, which did not cause corresponding clinical symptoms and were not treated additionally. The distribution of bone cement in group A was excellent in 25 cases, good in 19 cases, poor in 1 case and in group B was excellent in 45 cases, good in 4 cases. The distribution excellent rate of bone cement was higher in group B than in group A (<0.05). The VAS and ODI scores before operation and 1, 12, 18 months after operation were 8.29±0.74, 2.59±0.14, 3.75±0.38, 3.84±0.88 and 40.04±3.16, 9.24±2.82, 12.27±2.64, 15.83±2.58 in group A, 8.22±0.82, 2.54±0.19, 2.81±0.23, 2.82±0.45 and 39.98±2.05, 9.16±2.10, 9.46±2.41, 9.76±2.46 in group B. There was no significant difference in VAS and ODI scores at 1 month after operation between two groups (>0.05), but group A was higher than group B at 12 and 18 months after operation (<0.05). The vertebral height and Cobb angle before surgery, immediately after surgery, and 12, 18 months after surgery in group A were(59.17±1.42)%, (85.95±2.19)%, (75.27±3.45)%, (68.34±2.24)% and(23.83±3.37)°, (15.26±2.61)°, (17.63±2.16)°, (19.46±2.54)°, and in group B were(59.31±1.87)%, (89.19±2.53)%, (88.62±2.51)%, (88.59±2.62)% and(24.72±3.78)°, (14.91±2.28)°, (15.48±2.55)°, (15.86±2.81)°. Vertebral height Immediately after surgery was greater in group B than in group A and Cobb angle in group B was smaller than in group A (<0.05). During follow-up, there was no significant change in vertebral height in group B, while vertebral body recollapse in group A(<0.05). CONCLUSIONS In the treatment of osteoporotic vertebral compression fractures with intravertebral clefts, the manual reduction combined with PVP is more effective than single PVP, which can effectively prevent vertebral body recollapse and improve the long-term efficacy of patients.

OBJECTIVESince 2011 EB-APS conference, we hypotheses that phase switching of inspiration-expiration is dominantly initiated by oscillatory information PaO2, PaCO2 and [H+] via fast peripheral chemical receptors. However, the evidence of the waveform of ABG is lack.

METHODSSix surgery patients with normal heart function and negative Allen test, had been placed the arterial catheterization directly connected to 3 x 1 000 mm pre-heparin plastic pipe for continuous collecting arterial blood. We counted the number of heart beat for the blood collecting time, and separated the blood pipe into the heart beat numbers' short pieces using haemostatic forceps, then put pipe into iced water at once fir analyzing PaO2, PaCO2, pH and SaO2 as soon as possible. We selected two breaths cycles of waveform from each patient for data calculations of magnitudes and time interval.

RESULTSThe heart beat numbers for filling blood into pipe were 16 ± 2, and all covered more than 2 breathing cycles. Each breathing cycle is cover 5 ± 0.6 heart beat. There were significant changes of PaO2, PaCO2, [H+] a and SaO2 (i.e. the highest high values compare to the next lowest values, P < 0.05). The time interval of changing PaO2, PaCO2, [H+]a and SaO2 magnitudes were 11.28 ± 1.13 mmHg, 1.77 ± 0.89 mmHg, 1.14 ± 0.35 nmol/L and 0.52% ± 0.44% respectively.

CONCLUSIONThis simple continuous beat-by-beat arterial blood sampling and ABG analyzing method is new and practicable. We obtain a clear evidence of periodic parameters ABG waveform, which following breathing cycle.

OBJECTIVETo study the effects of a small interfering RNA targeting CXCR-4 (shRNA-CXCR4) on angiogenesis of human breast cancer cells.

METHODSThe expression of CXCR4 mRNA and protein in 3 breast cancer cell lines with CXCR-4 silencing mediated by shRNA-CXCR4 was detected by RT-PCR and Western blotting, respectively. The morphological changes of human umbilical vein endothelial cells (HUVECs) were observed in co-culture with human breast cancer cells after CXCR4 gene silencing.

RESULTSCXCR4 mRNA and protein expressions decreased significantly in MCF-7, MDA-MB-231 and MDA-MB-435s breast cancer cells after the gene silencing (P<0.05). Gene silencing with shRNA-CXCR4 in human breast cancer cells significantly inhibited the ability of HUVECs to form tubular structures in the co-culture (P<0.05).

CONCLUSIONGene silencing by shRNA-CXCR4 can obviously lower the angiogenesis-inducing ability of human breast cancer cells.
