Objective To study how polyclonal antibodies against ciliary neurotrophic factor (CNTF) reduce botulinum toxin-in- duced axonal sprouting and affect paralytic muscle.Design Experimental study.Participants 20 New Zealand rabbits.Methods In 10 rabbits randomly selected,left superior rectus were as control (Group 1),right superior rectus were injected with botulinum toxin A (BTXA) 2.5U (Group 3).At 14th day,bilateral superior recti were taken out under general anaesthesia.In the other 10 rabbits,left su- perior recti were injected equivalent physical saline (NS) as control (Group 2);right superior recti were injected with BTXA 2.5U,after 4 days,injected with 50?l polyclonal antibodies against CNTF at same site (Group 4).And at 14th day,bilateral superior recti were taken out for electron microscopy,dyed with acetylcholinesterase,argentums (Ag) to show nerve axonal sprout,and accounted and mea- sured with Leica microsystems.Main Outcome Measures The mean number of sprouts and the mean total length of sprouts,and the uhrastructure change of muscle by electron microscopy.Results In Group 1,the mean number of sprouts and the mean total length of sprouts were 5.75% and 10.53?m respectively;Group 2 were 6.11% and 11.16?m;Group 3 were 84.04% and 170.71?m;and Group 4 were 54.77% and 68.12?m.The differences were statistically significant (all P=0.000).Electron microscopy showed that after admin- istration BTXA alone (Group 3),muscle atrophied obviously,nerve myelin sheath increased,while the structure of nerve and muscle re- main invariable.The Group 4 showed that local myofilament disrupted and dissolved,degenerative myocytes necrotized and disintegrat- ed into fragments,which led to partial unreversible destroy.Conclusion Polyclonal anti-CNTF can reduce BTXA-induced axonal sprout- ing,lead to partial unreversible destroy of muscle,which may prolong the time of paralytic muscle resuming.It suggests that polyclonal anti-CNTF could prolong the duration of muscle paralyses induced by botulinum toxin.

National Journal of Andrology 2015;21(11):1010-1013
OBJECTIVETo observe the clinical effect of Shugan Yiyang Capsules combined with sertraline in the treatment of premature ejaculation (PE).
METHODSWe randomly assigned 192 PE patients to receive sertraline hydrochloride 50 mg qd (control group, n = 96) or sertraline hydrochloride 50 mg qd plus Shugan Yiyang Capsules at the dose of 4 capsules tid ( combination therapy group, n = 96) , both for 6 weeks. We compared the intravaginal ejaculatory latency time (IELT) and Chinese Index of Premature Ejaculation ( CIPE) scores between the two groups of patients before and after medication and at 6 weeks after drug withdrawal.
RESULTSCompared with the baseline, the IELT was significantly increased after 6 weeks of medication in the combination therapy group ([1.41 ± 0.53] vs [6.69 ± 3.56] min, P < 0.05) and the control group ([1.43 ± 0.48] vs [5.37 ± 2.91] min, P < 0.05), and so was the CIPE score in the former (9. 80 ± 2.06 vs 21.62 ± 4.76, P < 0.05) and the latter group ([9.41 ± 1.97] vs [20.85 ± 4.83] , P < 0.05). In comparison with the pre-medication indexes, the IELT ([3.77 ± 1.63] min) and CIPE score (16.92 ± 3.37) of the combined therapy group were remarkably improved at 6 weeks after drug withdrawal (P < 0.05), but not those of the control ([1.19 ± 1.34] min and 10.59 ± 2.38, P > 0.05).
CONCLUSIONShugan Yiyang Capsules combined with sertraline have a definite and lasting effect on premature ejaculation.

4. Determination of salidroside and crenulatin in Rhodiolae Sacrae Herbra by HPLC-ELSD
Chinese Traditional and Herbal Drugs 2014;45(8):1157-1159
Objective: To establish a determination method for the contents of salidroside and crenulatin in Rhodiolae Sacrae Herbra, and to compare the content differences of the two compounds in Rhodiolae Sacrae Herbra from different batches. Methods: Using HPLC-ELSD method and Kromasil C18 column (250 mm × 4.6 mm, 5 μm), with acetonitrile and water as mobile phase, gradient elution at flow rate of 1.0 mL/min, column temperature of 30°C, nitrogen flow rate of 2.0 L/min, drift tube temperature of 45°C, and gain of 2. Results: The linear of salidroside was 0.806-8.06 μg (r = 0.9996, n = 6), and the average recovery rate was 100.56%. The linear of crenulatin was 2.142-21.42 μg (r = 0.9999, n = 6), and the average recovery rate was 100.40%. Conclusion: This method is simple, and accurate, and has better reproducibility for the determination of the two compounds in Rhodiolae Sacrae Herbra. It could be used as a quantitative determination method for salidroside and crenulatin in Rhodiolae Sacrae Herbra.

Objective To explore the change of hippocampal neurons cholinergic receptor in rats with vascular dementia(VD).Methods VD rat models were established by employing improved method of Pulsinelli's four-vessel occlusion.1 month later,the abilities of learning and memory of VD models were tested by Morris water maze.The activities of acetylcholinesterase (AChE) in plasma and hippocampus were detected by the improved Ellman's colorimetric methods.The expressions of hippocampal nicotinic acetylcholine receptor (nAChR) subunits ?3,?4 and ?7 proteins and mRNA were detected respectinely by Western Blotting and RT-PCR,respectively.The results were compared with sham operation group.Results Compared to the sham operation group,the escape latency of Morris water maze test and the first time crossing platform in VD group were significantly prolonged,the number of crossing platform was decreased (all P
