OBJECTIVETo observe the clinical effects of needle-pricking therapy, a newly medical and minimally invasive technique, for functional retrograde ejaculation and to explore its mechanism. Methods Thirty-six patients with functional retrograde ejaculation were randomly divided into an observation group(19 cases) and a control group(17 cases) In the observation group,needle-pricking therapy was used at Guanyuan(CV 4) and bilateral sacral plexus nerve,lumbar 1 nerve and greater occipital nerve stimulating points,once a week. In the control group, midodrine tablets were prescribed orally,three times a day. All the treatment was given for 9 weeks. The clinical effects of the two groups were observed, and the levels of luteinizing hormone(LH), testosterone(Tes) and estra4 diol(E2) were compared between the two groups.

RESULTSThe total effective rate of the observation group was, 89. 47%(17/19), which was better than 47.06% (8/17) of the control group(P<0. 05). The LH and Tes were obviously increased and E2 was decreased compared with those before treatment in the observation group(all P< 0. 01). Tes was raised(P<0. 05) and E2 was apparently declined in the control group(P<0. 01). After treatment, the differences of serum LH and Tes were statistically significant between the two groups(both P<0. 01).

CONCLUSIONNeedle-pricking therapy has advantages for functional retrograde ejaculation probably in that stimulating lumbosacral nerves can strengthen the function of pelvic floor muscles and urethral expansion muscle and regulate sexual gland axis.

Objective To determine the variation of bone mineral density(BMD)and bone mineral content (BMC)in cadaveric lumbar vertebrae and investigate their significance in determining fracture modes and biomecha- nical properties.Methods The lumbar motion segments of the spines of 19 cadavers(mean age:56 years)were compressed to failure.The BMD and BMC of the cranial and caudal endplates were determined,along with the BMD and BMC of the upper and lower 1/3 transverse sub-endplate layers and the middle 1/3 transverse layer.The anteri- or,middle and posterior 1/3 vertical parts,anterior and posterior 1/2 vertical parts and the whole BMD and BMC were measured by using dual energy X-ray absorptiometry as well.All the data were analyzed statistically.Results Among the 19 segments,macrography after dissection revealed that 16 had been fractured,about 84.2%.The frac- ture always occurred in the centre or in the anterior part of the endplate.Within a vertebral body,the BMD and BMC of the cranial endplate were less than those of the caudal endplate,and the cranial 1/3 transverse layer and middle layer had lower BMD and BMC readings than the caudal layer.For the vertical region,from the anterior 1/3 to the posterior 1/3,or from the anterior 1/2 to the posterior 1/2,the BMD and BMC increased.For the endplate around the disc,the BMD of upper endplate was higher than that of the lower one,but the BMCs were equal.In one motion segment,the failure load correlated positively with BMD,and with the BMC of the endplate and the sub-endplate bone.Conclusion The variations in BMD and BMC within a vertebra and around a disc can explain why vertebral fractures are concentrated on the upper endplate,and why compressive fractures are always wedge-shaped.This un- derstanding can assist in the placement of inter-vertebral spacers.

OBJECTIVETo find the optimal dosage of Salvia injection in treating chronic hepatitis B caused liver fibrosis.

METHODSSixty-four patients, whose diagnosis was confirmed as chronic hepatitis B caused liver fibrosis and differentiated by TCM typing as blood stasis blocking Collaterals type, were selected and randomly divided by lottery method into the large, middle and small dose of SI treated groups and the control group. All the patients were treated with modified Gexia Zhuyu Decoction, to the patients in the SI groups, 24 ml, 16 ml and 8 ml of SI were additionally administered by intravenous dripping respectively. The therapeutic course was 45 days. The clinical symptoms and signs; liver functional indexes as alanine transaminase (ALT), aspartate aminotransferase (AST) and albumin (ALB); and liver fibrosis indexes as procollagen type III (PC-III), collagen type IV (C-IV) and hyaluronic acid (HA), were measured before and after treatment.

RESULTSDifferent dosages of SI all could improve the clinical symptoms, and lower levels of ALT, AST, HA, PC-III and C-IV. Treatment of large dosage SI showed the best efficacy, superior to that of middle and small dosage SI, but no significant difference was found between the efficacy of the latter two.

CONCLUSIONAnti-liver fibrosis effect of large dosage SI is better than that of middle or small dosage SI.

OBJECTIVETo observe the effects of thermal stress on proliferation of human vascular endothelial cells (VECs) and explore its significance.

METHODSChanges of VECs proliferation were investigated with (3)H-TdR incorporation method after ECV304 was treated at 43 degrees for 2 hours, while expressions of intercellular adhesion molecule-1 (ICAM-1), inhibitor of differentiation-1 (ID1), and P16 and P21 proteins were determined by Western Blotting.

RESULTSThe effect of inhibition of VECs growth after thermal stress was detected by (3)H-TdR incorporation experiment. Western blotting showed ICAM-1, a marker of activated endothelial cells, was increased markedly after thermal stress. Expression of ID1 protein declined gradually with increasing expressions of its downstream genes, P16 and P21 following the thermal stress.

CONCLUSIONSThermal stress could strongly activate VECs and inhibit proliferation of VECs through ID1, thus down regulating cyclin-dependent kinase inhibitors, P16 and P21, which might be an essential pathway for recovery of VECs after thermal stress.

To silence the expression of K-RASAsn12 in human pancreatic cancer cell line by vector-based RNAi(RNA interference) technique,two single-strand DNA sequences encoding mutant-specific shRNA (short haipin RNA) for K-RASAsn12 were synthesized and then inserted into pSilenCircle. The recombinant plasmid was called pSC-K-RASAsn12. According to the same method, pSC-GFP encoding shRNA for GFP was gained. Both recombinant plasmids were transfected into human pacreatic cancer cell line AsPC-1 and BxPC-3. The expression level of K-RASAsn12 was detected by semi-quantitative RT-PCR and Western blot. The result indicated that the recombinant plasmid edcoding mutant-specific shRNA for K-RASAsn12 can inhibit significantly the expression of K-RASAsn12 without affection of wild-type K-RAS(K-RASWT)in Human Pancreatic Cancer Cell Line.

Objective To explore the correlation between MSCT perfusion parameters and biologic characters in nasopharyngeal carcinoma(NPC),and to investigate the clinical utility of MSCT perfusion for NPC.Methods Nasopharynx in 49 cases was studied using MSCT perfusion imaging,including 30 NPC cases before radiotherapy,14 post-radiotherapy NPC cases,and 5 cases of normal nasopharynx as controls. The perfusion data of tumors and nasopharyngeal wall such as blood flow(BF),peak enhancement index (PEI),time to peak (TTP),and blood volume (BV)were calculated.MVD defined by CD34 stain was counted in 16 cases of NPC.The correlation of MSCT perfusion parameters,MVD,and clinical stage was analyzed.Results 1 case of NPC failed in CT perfusion exam.In NPC group (n=29),BF,PEI,TTP, and BV were (48.6?16.9)ml?100 g~(-1)?min~(-1),(32.3?7.9)HU,(17.5?4.9)s,and (12.8? 4.4)ml?100 g~(-1),respectively.BF,PEI,TTP,and BV in control group (5 cases)were (15.9? 5.9)ml?100g~(-1)?min~(-1),(12.6?1.3)HU,(22.6?6.9)s,and (3.5?0.5)ml?100 g~(-1), respectively,and those in post-radiotherapy group (14 cases)were (25.2?7.0)ml?100 g~(-1)?min~(-1), (19.8 ?5.9)HU,(22.6?4.3 )s,and (6.1?2.4)ml?100 g~(-1),respectively.The perfusion values in NPC group had significant difference compared with those in the other two groups (P
