Objective: To present a modified option to surgical crown lengthening for repair of biologic width loss. Methods: The alternative to the traditional method involves reshaping the fractured root surface in combination with conservative removal of the supporting alveolar bone to rebuild the biological width. Although these teeth were considered as not suitable for the traditional methods, 7 teeth from 7 patients with fracture surface located lower than alveolar bone crest were treated by this modified method of surgical crown lengthening. Restoration was accomplished on these teeth two month later. Periodontal index such as tooth mobility, plaque index, probing depth and bleeding index were recorded and followed up. Results: The mean follow-up period was 17 months (ranged from 10 to 31 months). Result of surgery and restoration of these 7 teeth was satisfactory. The gingival tissue remained healthy and esthetic with good function. Conclusion: This modified surgical crown lengthening can be used as an alternative to the traditional method to save more fractured teeth.

Objective To evaluate the analgesic effect of parecoxib in total knee arthroplasty (TKA) and total hip arthroplasty (THA).Methods The study was a prospective,randomized and double-blind trial and was operated by the same group of surgeons in 101 patients with TKA and 105 patients with THA.According to analgesic protocol,the patients were divided into three groups:Group One ( intravenous injection with parecoxib),Group Two ( periarticular injection with parecoxib) and Group Three ( the control group).The postoperative visual analog scores (VAS),range of motion ( ROM),the ability of straight leg raising and the incidence of nausea and vomiting complications were examined and compared between the three groups.Results There were no significant differences in VAS (6,12,24,36,48,72 hours after operation),ROM ( 24 hours after operation) and the ability of straight leg raising between Group One and Group Two ( P ＞ 0.05 ),but all of them were significantly higher than those in Group Three ( P ＜ 0.05 ).Nausea,vomiting and other adverse effects did not significandy increase with the use of parecoxib.Conclusions Both intraoperative intravenous injection and periarticular injection with parecoxib have a good analgesia effect on TKA and THA,which are beneficial to the rapid recovery of joint function in patients.The simple and practical method provides an effective adjunct to a multimodal analgetic approach in improving the postoperative course of TKA and THA.

Objective To evaluate the efficacy of a new pelvic muscle gymnastic exercise in the treatment of stress urinary incontinence (SUI).Methods Prospectively,we randomly recruited 60 cases with mild and moderate SUI.We use ICI-Q-SF,pad Test and urodynamics to assess the degree of incontinence,volume of leakage,maximum urethral pressure and functional urethral length before and after intervention.Results The ICI-Q-SF score,volume of leakage,maximum urethral closure pressure and functional urethral length in study group before treatment were 11.6 ±4.2,(5.9 ±2.2) ml,(39.4 ± 12.5) cm H2O and (2.5 ±1.2) cm.The indicators in control group were 10.3 ±2.2,(5.8 ±1.3) ml,(41.3 ±8.9) cm H2O and (2.1 ± 0.5) cm respectively.There was no significant difference between the 2 groups (P ＞ 0.05).The ICI-Q-SF score,volune of leakage and maximum urethral closure pressure in study group after treatment were 7.7 ± 2.7,(1.8 ± 1.2) ml and (65.9 ± 8.9) cm H2O,which were significantly improved than the values of10.1 ±2.1,(5.7 ± 1.1) ml and (44.6 ±9.5) cm H2O in control group (P ＜0.05).Conclusions The new pelvic muscle exercise may play an important role in the treatment of mild and moderate SUI.Therefore,it could be recommended to the patients with mild and moderate SUI.

Objective To assess the long-term outcome of transurethral resection of the prostate (TURP) in men with different maximum detrusor pressure (Pdet.max).Methods 113 neurologically intact men diagnosed with BPH and undergone surgical intervention in our department were enrolled between Feb.2009 and May 2012.All patients had completed the International Prostate Symptom Score (IPSS) and quality-of-life (QOL) questionnaires and had undergone a full urodynamic analysis before surgery.The outcomes were assessed at 24 months postoperatively using the IPSS score,QOL score,and maximum urinary flow rate (Qmax).Results After 24 months follow-up,3 cases in the poor symptom improvement group could not void.The average Pdet.max of these three patients was (15.7±5.1) cmH2O,which was statistically significantly lower than that of the other three groups [(102.7±39.3),(95.9±42.8),(77.0±27.4) cmH2O] (P＜0.05).Nine cases in the poor functional improvement group whose average Pdet.was (32.5± 16.6) cmH2O,which was statistically significantly lower than that of the other three groups [(115.2±36.3),(87.5±28.7),(75.5±46.9) cmH2O] (P＜0.05).Conclusions Urodynamic analysis plays an important role in judging the efficacy of TURP.Patients with a Pdet.max less than 32.5 cmH2O may not have an objectively successful result from surgery treatment.

Objective To compare the biomechanical pull-out strength (POS) of three different fixations in upper thoracic vertebras using translaminar screws (TLS), translaminar facet screws (TLFS), and transpedicle screws (TPS), respectively. Methods Nine fresh human cadaveric cervicothoracic junction spines specimens which including T1-T3 vertebras were harvested. The vertebras specimens were scanned using dual-energy radiograph absorptiometry for bone mineral density. Both of screw insertion techniques at each vertebrae was randomized. All the screw insertions were based on direct observation and the CT scan on the pedicles. The peak of insertional torque (IT) was recorded and axial pull-out testing was performed to simulate intraoperative failure of fixation. Results The mean peak IT of the TFLS, TPS and TLS were (0.43±0.01), (0.40±0.01), (0.35±).01) N·m, respectively. There was no statistically significant difference between the TFLS and TPS, and between the TPS and TLS was same. But the TFLS generated statistically greater peak 1T in comparison with the TLS(t=-13.86, P＜0.05). The mean POS of TLFS was (771±106) N,which had no statistically significant difference in comparison with the TPS(733±65) N. And the TLS (663±86) N was same. But the TFLS generated statistically greater POS in comparison with the TLS (t=9.907, P＜0.05). The peak IT showed a strong positive correlation with POS in three screw techniques. Bone mineral density correlation with POS in all methods of fixation. Conclusion It was not a significant difference to compare POS of TLS and TLFS to that of TPS respectively. TLS and TLFS appear to be a biomechanically sound alternative in the upper thoracic spine, and appear to be a safe and effective technique for instrumenting the upper thoracic spine.

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.
