OBJECTIVETo compare the efficacy between elongated needle therapy and regular needle therapy at Tiantu (CV 22) on the basis of xingnao kaiqiao (activiting brain and regaining consciousness) acupuncture therapy so as to explore the effective therapeutic method in treatment of dysphagia induced by bulbar palsy.

METHODSSeventy one cases of dysphagia induced by bulbar palsy were randomized into two groups. The xingnao kaiqiao acupuncture therapy was applied at Shuigou (GV 26), Neiguan (PC 6), Sanyinjiao (SP 6) and the others in the two groups. In the elongated needle therapy group, on the basis of xingnao kaiqiao acupuncture therapy, the elongated needle was used to puncture Tiantu (CV 22). In the regular needle therapy, the regular acupuncture technique was used at Tiantu (CV 22). In both groups, the treatment was given once a day in a week except Sunday and lasted for 4 weeks totally. Before and after treatment, the swallowing condition and the standardized swallowing assessment (SSA) were observed in the patients and the efficacy was compared between the two groups.

RESULTSThe total effective rate was 97.2% (35/36) in the elongated needle therapy group, which was better than 77.1% (27/35) in the regular needle therapy group (P<0.05). After treatment, SSA score was reduced significantly as compared with that before treatment in the two groups (both P<0.05). SSA score in the elongated needle therapy group was reduced much more apparently as compared with that in the regular needle therapy group after treatment (P<0.05).

CONCLUSIONOn the basis of the xingnao kaiqiao acupuncture therapy, the elongated needle therapy at Tiantu (CV 22) achieves the superior effect on bulbar palsy-induced dysphagia as compared with the regular acu- puncture at Tiantu (CV 22).

Objective To investigate the effect of indomethacin on prevention of heterotopic ossification (HO)after operative treatment of acetabular fractures.Methods Fifty patients with acetabular fractures received in our department operative treatment through Kocher-langenbeck(K-L)approach and oral administration of in- domethacin afer operation from February 2001 to August 2003.Forty-eight of them were successfully followed up for incidence of HO and their clinical functions were assessed.The results were compared with those of 40 patients who had been treated with the same operative procedures but without oral administration of indomethacin in our depart- ment from March 1993 to May 1998.The patients who could not tolerate the drug were not included.Results The follow-ups averaged 22.8 months(range,6 to 39 months).HO occurred in eight cases.The incidence of HO was 16.7%(8/48).According to Brooker evaluation of HO,five cases were rated as degreeⅠ,three as degreeⅡ, and none as degreeⅢorⅣ.The incidence of severe HO was 0.In the control group,the incidence of HO was 35.0%(14/40)and the incidence of severe HO was 10.0%(4/40).The differences were statistically significant (P＜0.05).Conclusion Oral administration of indomethacin after operative treatment of acetabular fractures can inhibit HO.

Objective To evaluate the efficiency of our self-designed enriched filtrator of stem cells in screening and collecting enriched human bone marrow stem cells (BMSCs) for rapid construction of bioactive materials.Methods Bone marrow blood from 32 patients was circulated in our self-designed enriched filtratorand filtered through beta-tricalcium phosphate(β-TCP).The numbers of BMSCs were counted pre-and post-filtration to assess the enrichment efficiency.The numbers of nucleated cells,red blood cells and platelets were compared pre-and post-filtration to assess the effects of the enriched filtrator of stem cells on blood cells.Bacteriological examinations were performed to test the safety of the device.Scanning electron microscopy was carried out to observe the adhesion of BMSCs on β-TCP.Results There was a significant difference between the pre-fihration colony number of BMSCs cultured (232.8 ± 128.6/mL) and the post-filtration one (37.8 ± 34.9/mL) (t =10.743,P ＜ 0.001).The efficiency of BMSCs enrichment of the device was 85.6％ ±8.4％ (from 63.8％ to 97.1％).There were no significant differences between pre-filtration and post-filtration in the numbers of nucleated cells [(16.8 ± 5.4) × 109/mL versus (16.3 ±5.0) ×l09/mL],red blood cells [(3.9±0.6) ×1012/mL versus (3.8±0.6) ×1012/mL] and platelets [(120.4 ± 54.6) × 109/mL versus (123.0 ± 51.8) × 109/mL] (P ＞ 0.05).All the bacteriological examinations of the bone marrow samples were negative.After in vitro osteogenic induction culture,formation of numerous BMSCs colonies was observed on the β-TCP by scanning electron microscopy.Conclusion Since our self-designed enriched filtrator can efficiently collect enriched BMSCs and combine them with β-TCP simultaneously,the device is capable of rapid and safe construction of bioactive materials.

Objective Streptococcus pneumoniae can form biofilms .The aim of this study was to investigate the biofilm forma-tion of Streptococcus pneumoniae and the relationship with antibiotic resistance of penicillin etc . Methods A total of 147 clinical iso-lates of Streptococcus pneumoniae were collected from 7 teaching hospitals in Nanjing from 2010 to 2012.Minimal inhibitory concentration (MIC) of penicillin, erythromycin, cefuroxime and ceftriaxone were determined by agar dilution method .Streptococcus pneumoniae with various penicillin MIC was selected randomly as follow:MIC≤0.065μg/mL, 0.5μg/mL, 2μg/mL and≥4μg/mL, which was incuba-ted to form biofilms in 96-well plates and 24-well plates for 24 hours.The A values at 570 nm was measured and the biofilm was observed through confocal laser scanning microscope ( CLSM) . Results The biofilm semi-quantitative detection and CLSM both displayed that all strains formed biofilms.The A value of the group which penicillin MIC was ≤0.065μg/mL (0.228 ±0.063) was higher than the 0.5μg/mL group (0.200 ±0.061) and the≥4μg/mL group (0.186 ±0.050) (P<0.05) , and there was no difference among the groups which penicillin MIC were 0.5μg/mL, 2μg/mL and≥4μg/mL, respectively (P>0.05).The A value of the group which erythromycin MIC was ≤0.5μg/mL (0.211 ±0.068) was higher than the ≥4μg/mL group (0.201 ±0.052) (P>0.05).The A value of the group sensitive to cefuroxime (0.216 ±0.062) was higher than the group resistant to cefuroxime (0.196 ±0.054) (P<0.05). Conclusion Streptococcus pneumoniae can form biofilms .Streptococcus pneumoniae with high antibiotics MIC has a trend of weakened biofilm formation .

Objective To analyze the features of the latency and interval in somatosensory evoked potentials (SEP) of the upper limbs in subacute combined degeneration(SCD),and evaluate the SEP of the upper limbs in the diagnosis of SCD.Methods Thirty-four defined SCD patients and 22 healthy controls were included in this study.The patients underwent the SEP test and the magnetic resonance imaging(MRI)of spinal cord.The SEP results of the patients were compared with those of the controls.The results of the SEP,which were divided into the peripheral part and central part to be evaluated,were also compared with the related results of the SEP and MRI.Results Compared with the controls,the N9 ((10.80 ± 1.07) ms vs (10.23 ± 0.64) ms,t =3.223),P14 ((17.28 ± 2.56) ms vs (14.62 ± 0.84) ms,t =6.643),N9-P14 ((6.48±2.27) ms vs(4.40-0.58) ms,t =5.951) in the upper limbs and N9((12.11 ±0.83) ms vs (10.93±0.56) ms,t=5.690),P30((36.96±5.56) ms vs(30.37±2.20) ms,t=7.217),P38 ((46.94 ±5.83) ms vs(39.80 ±2.54) ms,t =7.353) in the lower limbs of SCD patients were prolonged (all P ＜0.01),however,the P14-N20 was prolonged without statistical significance.The abnormality of SEP was 80.9％ (110/136),in which the abnormality of the upper limbs was 85.3％ (58/68)while that of the lower limbs was 76.5％ (52/68).N9-P14 had the highest abnormality rate which was 72.1％ (49/68).The patients with SCD with normal N9 had prolonged N9-P14 ((5.98 ± 1.90) ms vs(4.40 ± 0.58) ms,t =5.267,P ＜ 0.01).Conclusions Subacute combined degeneration can involve not only the peripheral part of the somatosensory pathway but also the central part including the brainstem and brain.In the SEP of upper limbs,N9-P14 has the highest abnormality rate which suggests that the part from cervical spinal cord to the brainstem may be the most vulnerable in SCD.The test of SEP in the upper limbs may provide evidence for the damage in the central part in SCD.
