OBJECTIVETo observe the clinical efficacy difference between segmentation scraping and conventional acupuncture for cervical spondylosis (CS) so as to provide effective treatment method.

METHODSEighty-five cases of cervical type of CS were randomly divided into a scraping group (44 cases) and an acupuncture group (41 cases). The segmentation scraping therapy was used in the scraping group. The scraping group was treated with focusing on scraping the head and joint part of neck and occiput in the upper cervical spine injury, and focusing on scraping the lower section of cervical and shoulder in the lower cervical spine injury, once every seven days, totally for 3 times. In the acupuncture group, Fengchi (GB 20),Wangu (TE 5), Tianzhu (BL 10),Neck-Jiaji (EX-B 2), etc. were selected,once daily,for 15 days. The visual analogue scale (VAS) was used to evaluate the immediate analgesic effect after the first treatment and the clinical efficacy was observed after the end of treatment.

RESULTSAfter the first treatment, the score of VAS was decreased significantly in the scaping group (P < 0.01), but there was no significant difference in the acupuncture group compared with those before treatment (P > 0.05); the score of VAS in the scaping group after the first treatment was lower than that in the acupuncture group (3.66 +/- 0.74 vs 5.43 +/- 0.35, P < 0.01). Compared with before treatment, the scores of VAS were decreased significantly after treatment in two groups (both P < 0.01), but without significant difference between two groups (P > 0.05); the effective rate was 95.5% (42/44) in the scaping group and 87.8% (36/41) in the acupuncture group, the curative effects were similar (P > 0.05).

CONCLUSIONBoth of scraping and acupuncture therapies have good analgesic effect for cervical spondylosis, and overall effects are similar, but the immediate analgesic effect of scraping thrapy is better than that of conventional acupuncture.

Objectivc To investigate the protective effect of simvastatin on retinal ganglion cells (RGC) after optic nerve crush (ONC).Methods Together 50 Kunming mice were randomly divided into normal group,sham group,ONC group and simvastatin protection group.The mice in the normal group were untreated,the sham group was treated with the exposure of the optic nerve without injury,the ONC group mice underwent ONC operation on the left eyes,followed by intravitreal administration of equilibrium solvent [50 mg · mL-1 ethanol plus 1 mol · L-1 NaOH,which were activated by 1 mol · L-1 HC1 (pH 7.2)],and the simvastatin protection group was intravitreally injected different concentrations of simvastatin (0.5 g · L-1,1.0 g · L-1,1.5 g · L-1) after ONC operation.Brn3a immunofluorescence staining,HE staining and toluidine blue staining were used to detect the apoptosis of RGC and pathological changes of optic nerve.Results On day 7 after operation,in the ONC group,the apoptosis of RGC was observed obviously,with the survival rate dropping to (35.1 ± 3.9) ％,and the thickness from the retinal ganglion cell layer to outer nuclear layer was decreased from (123.13 ± 1.04) μm to (97.48 ± 2.33) μm,which was significantly thinner than that in the control group (P ＜ 0.01);moreover,the fibrous bundle of optic nerve disappeared,and the neuroglial cells were clustered into groups,as well as the axons showed swelling and serious degeneration,but after intravitreal injection of 1.0 g · L-1 simvastatin,the survival rate of retinal ganglion cells increased to (76.3 ± 3.7) ％ (P ＜ 0.05),and the aforementioned thickness was increased to (111.39 ± 4.06) μm,which was statistically significant when compared with the ONC group (P ＜ 0.01).The degeneration of optic nerve was improved,and the structure of neuroglial cell axons and the nerve fibers became normal.Conclusion Simvastatin can reduce the optic nerve degeneration and improve the survival rote of retinal ganglion cells.

OBJECTIVETo investigate the safety and medication cycles of intermittent androgen deprivation (IAD) in the treatment of aggressive prostate cancer.

METHODSBased on prostate cancer clinical staging, we divided 178 patients with aggressive prostate cancer into groups A (T3-4N0M0), B (TXN1M0) and C (TXNXM1) to receive maximum androgen blockage for at least 6 months till the PSA level remained at < or = 0.2 microg/L for 3 months, followed by an off-period (without medication). The on-period was initiated when the PSA level was > 4 microg/L, and then stopped again when it was < or = 0.2 microg/L. We recorded and compared the patients' age, baseline PSA levels, Gleason scores, duration of on- and off-period, and time to tumor progression.

RESULTSThe baseline PSA levels of the 3 groups were (27.5 +/- 14.6), (43.4 +/- 21.8) and (62.8 +/- 44.6) microg/L, P < 0.01; the follow-ups averaged (38.4 +/- 9.6), (33.1 +/-14.0) and (28.3 +/- 14.3) months; and the times from medication initiation to tumor progression were (37.4 +/- 6.6), (27.4 +/- 10.2) and (16.6 +/- 4.4) months, respectively. Group A showed a longer off-period and more medication cycles than B and C (P < 0.01). Nineteen patients completed 5 cycles and 2 died of cardiovascular events in group A. PSA elevation and cancer progression occurred after 3 cycles at most in group C. Six died in group B, 1 of metastatic prostate cancer, and 36 died in group C, 21 of metastasis.

CONCLUSIONFor local aggressive prostate cancer, IAD can effectively slow down tumor progression, reduce adverse events and improve patients' quality of life.

OBJECTIVETo compare the detection rates of prostate cancer (PCa) and complications of the transrectal ultrasonography (TRUS)-guided 24-core saturation scheme versus 14-core scheme for transperineal prostate biopsy in patients with total PSA < 20 microg/L.

METHODSWe performed TRUS-guided 24-core saturation transperineal biopsy for 136 patients suspected of PCa (24-core group) and 14-core biopsy for another 116 (14-core group). We compared the PCa detection rates and post-biopsy complications, such as gross hematuria, urinary system infection, and acute urinary retention between the two groups.

RESULTSThe baseline characteristics of the two groups were comparable with regard to the mean age, prostate volume and PSA level (P>0.05). The positive rates of PCa detection were 48.53% (66/136) in the 24-core group and 17.24% (20/116) in the 14-core group (P<0.001), and the positive rates of samples were 8.09% and 2.83%, respectively (P=0.012). The detection rate of PCa in the apex zone was significantly higher in the former (11.76%) than in the latter (1.72%) (P<0.05). There were no statistically significant differences in such post-biopsy complications as gross hematuria, urinary system infection, and acute urinary retention between the two groups (P>0.05).

CONCLUSIONTRUS-guided 24-core saturation transperineal biopsy of the prostate is superior to the 14-core scheme for its higher detection rate of PCa, particularly PCa in the apex zone, and lower incidence of complications in patients with PSA < 20 microg/L.

In order to improve the yield of bacterial cellulose (BC), the fermentation medium of BC-producing strain J2 (Gluconobacter) was optimized, and BC ultra-micro-structure was observed. Initially, Plackett-Burman design was employed to evaluate eight variables which were relevant to BC production. Three statistically significant parameters including yeast extract, ZnSO4, ethanol were selected and other 5 variables were not significant (P > 0.05). The optimized levels of three variables were defined by Box-Behnken design and response surface methodology (RSM). BC ultra-micro-structure was observed by scanning electron microscope (SEM) with cotton cellulose as comparison. The results indicated that the BC yield under the optimum fermentation medium was 11.52 g/100 mL, which was as 1.35 times as that under the original fermentation medium. The SEM photos manifested that bacterial cellulose ribbon, with a diameter less than 0.1 microm, was less than cotton cellulose ribbon. The bacteria inside the cellulose net were eliminated after the NaOH treatment.
