Objective To investigate the cavernous nerves innervation from prostate apex to glans penis and the relation between cavernous nerves and surrounding tissues and organs. Methods The urethra and penises of three formalin preserved adult cadavers were removed from prostate apex to glans penis.The sections underwent hematoxylin-eosin staining and Bielschowsky nerve staining.The course and distribution of cavernous nerves and relationship between the cavernous nerves and surrounding tissues and organs was observed microscopically and photographed from prostate apex to glans penis. Results From serial sections we found when nerve fibres run along prostate apex,while surrounding the lateral and dorsal aspects of prostate apex and urethra.from 30'clock to 9 0'clock.Most fibres went through smooth muscle and some of them went through the periphery striated muscle and urogenital diaphragm.The distance to urethra lumen was only 3-5 mm.After the nerve fibres went distally and anteriorly,they accompanied closely with cavernous vein plexus and then went into corpora cavernosa.At the distal end of corpora cavernosa,there were"windows"through which the neurovascular bundles communicated between corpora cavernosa and glans penis just like doors to glans penis. Conclusions When nerve fibres run from prostate apex to urogenital diaphragm,along dorsal lateral aspect of prostate and urethra,there are only 3-5 mm to the urethra lumen,so it is very easy to be injured in traumas or operations.In the urethral bulb fragment,the nerves run anteriorly and laterally.out of the periphary muscle,so the cavernous nerves will not be i~ured when dissect urethra bulb from surrounding muscles.Dissect glans penis from distal end of penis in operation would be avoided in order to protect the cavernous nerves between corpora cavernosa and glans penis.

Fura—2 was used as a Ca~(2+) indicator to determine the intracellular calcium ion concentra-tion(〔Ca~(2+)〕i)of rat peritoneal macrophages(RPM?s),and APAAP enzyme immnoassay was ap-plied to detect the expression of Ia antigens on RPM?s.The results showed that norepinephrine(NE,10~(-9)mol/L)could markedly increase the〔Ca~(2+)〕i of the RPM?s(p

BACKGROUND:Because of osteoporosis, short-segment transpedicular fixation or screw-rod system fixation is prone to screw loosening depending on its poor anti-pul-out strength in patients with thoracolumbar fracture with ankylosing spondylitis.
OBJECTIVE:To probe the clinic outcomes of multi-segment transpedicle spinal fixation for thoracolumbar fractures with ankylosing spondylitis.
METHODS:Eleven patients with ankylosing spondylitis combined with thoracolumbar fracture in the Fourth Department of Orthopedics, Meizhou Hospital, Sun Yat-sen University, China from January 2009 to December 2012 were selected. Al the patients underwent posterior reduction and multi-segment transpedicle spinal fixation, among whom, six cases were subjected to internal fixation through the pedicle of fractured vertebra.
RESULTS AND CONCLUSION:Al of the 11 patients were fol owed up for 13 to 36 months. Solid bone healing was achieved in al of the patients, and there were no complications related to the internal fixation systems such as loosening or breakage. Three cases of spinal cord injury achieved Frankel’s class E from class C recovery. Lumbodorsal pain rate achieved 100%according to the Japanese Orthopaedic Association scoring. Results confirmed that it is effective to treat thoracolumbar fractures with ankylosing spondylitis by posterior reduction and multi-segment transpedicle spinal fixation. Strong internal fixation and fracture union can be achieved by operation.

Objective To evaluate the efficacy of combination therapy with finasteride and doxazosin in benign prostatic hyperplasia/ lower urinary tract symptoms (BPH/LUTS) patients with intravesical prostatic profusion (IPP).Methods A total of 322 BPH/LUTS patients who accepted combination therapy with finasteride and doxazosin were enrolled in this study.Patients were divided into 4 groups according to the degree of IPP:group Ⅰ(IPP＞10 mm),group 2 (IPP between 5 mm and 10 mm),group 3 (IPP＜5 mm),control group (without IPP).All patients were received inasteride 5 mg once per day and doxazosin 4 mg once per day for 6 months.International prostate symptom score (IPSS),prostatic specific antigen(PSA),ultrasonographic and urcdynamic evaluation were compared before and after treatment.The correlations between the above factors and IPP were estimated by Logistic regression analysis.Results After 6 month of treament,the changes of IPP degree and the maximal urinary flow rate (Qmax) had no significant differences in group 1,group 2 and group 3 as compared with before treatment (all P＞0.05).The IPSS in group 1 was not significantly different before and after treatment (P＞0.05).There were significant differences in the PSA level,IPSS,total prostate volume (TPV),transition zone volume (TZV),residual urine volume (PVR) in the 4 groups before and after treatment (all P＜0.05).Logistic regression analysis showed that PVR and Qmax had positive and negative correlations with IPP (P＜0.001 and P=0.024),respectively.Conclusions Combination therapy with finasteride and doxazosin can significantly improve the symptoms of LUST and reduce the total prostate volume in patients with BPH/LUTS,but for BPH patients with IPP,the combination therapy can not effectively alleviate the degree of IPP.The increase of residual urine volume and decrease of Qmax may enhance the risk of bladder outlet obstruction in BPH patients with IPP.

[ Objective ] To investigate the therapeutic effect of Chinese herbal medicines, which have the actions of dispersing stagnated liver-Qi and promoting bile secretion, clearing heat and removing damp, activating blood and removing blood-stasis, in the treatment of the third-level or above intrahepatic biliary duct stone. [Methods] After the routine surgical treatment including cholecystectomy, choledochotomy with T-tube drainage and choledochoscope lithotomy, 42 cases of third-level or above intrahepatic biliary duct stone received Dandao Paishi Mixture (DPM, mainly composed of Herba Lysimachiae, Radix Clematidis, Herba Artemisiae Scopariae, Radix Aucklandiae, Rhizoma Curcumae Longae, Radix Curcumae, etc.) for oral use. The effects of DPM on the intrahepatic biliary duct stone were evaluated after treatment. [Results] Before the treatment of DPM, the stones in third-level or above intrahepatic biliary ducts cannot be taken out; after the treatment of DPM, T-tube reverse biliary contrast examination showed that stones were removed in 39 (92.9%) cases, stones still existed in the common bile duct in 3 cases and then were removed by lithotomy through T-tube sinus of the common bile duct with Olympus fiber choledochoscope 8 weeks later. [Conclusion] DPM has good lytholytic and lithagogue effects for the treatment of third-level or above intrahepatic biliary duct stone and for intrahepatic biliary duct incarcerated stone. It can also reduce the postoperative residue of stone and recurrence rate.

Objective To determine whether LTB4 could indirectly stimulate human osteoclast differentiation in RA through increasing RANKL expression of RAFLs. Methods We utilize the coculture model of RAFLs and monocyte which were stimulated in the presence of 2.5 ng/ml M-CSF in the control group, 2.5 ng/ml M-CSF +10-8 mol/L LTB4 in the experimental group A, 2.5 ng/ml M-CSF+10-8 mol/L LTB4+100 ng/ml OPG in the experimental group B. After culture for 3 weeks, through TRAP staining we counted the number of multinucleated TRAP staining positive osteoclast-like cells stained with TRAP to evaluate the differentiation effect in each group. Results There was almost no osteoclast-like cell in the control group and the experimental group B. Whereas there were many osteoclast-like cells in the experimental group A. Conclusion LTB4 can indirectly stimulate human osteoclast differentiation in RA through increasing RANKL expression of RAFLs.

Aim To investigate the activation of prote-ase-activated receptor 2 ( PAR2 ) in regulation of the expression of epidermal growth factor receptor ( EGFR) and apoptosis of lung cancer ( LC) cells. Methods LC cells A549 and its EGFR-silenced counterpart were incubated in the medium added with tryptase. Quanti-tative RT-PCR and Western blotting were used to de-tect the expression of EGFR in A 5 4 9 cells . The apop-tosis and Bax/Bcl-xL of cells were also recorded. Re-sults Treating A549 cells with tryptase in the culture for 48 hrs resulted in a marked increase in the expres-sion of EGFR in A549 cells. Marked decreases in a tryptase dose-dependent manner in apoptotic A549 cells were detected in the presence of tryptase. Expo-sure to tryptase markedly decreased the levels of Bax and increased the levels of Bcl-xL in A549 cells, which were not shown in EGFR-deficient A549 cells. Conclusion Tryptase can increase the expression of EGFR in LC cell line, A549 cells, which protects A549 cells from apoptosis, increases Bcl-xL, and sup-presses Bax in A549 cells.
